Description

The present invention relates to a drug diffuser that diffuses various drugs into the air.

Conventionally, this type of chemical diffuser is known to include a chemical holder that holds a chemical that is volatile at room temperature and a container that contains the chemical holder (see, for example, Patent Documents 1 to 3).

The container in Patent Document 1 is plate-shaped and has a front cover part and a rear cover part on the front side and rear side, respectively. The front cover part and the rear cover part are made of many flower-shaped motifs connected vertically and horizontally, and have many openings for dispersing the drug. The drug holder is made of nonwoven fabric or the like molded into a shape that corresponds to the shape of the container.

The container in Patent Document 2 has a front portion and a rear portion. A number of bars extending laterally are provided on the front portion and rear portion of the container at intervals in the vertical direction. The spaces between the bars arranged in the vertical direction form openings for dispersing the drug. The cross-sectional shape of each bar is such that the width of the portion located on the outside of the container is narrower than the width of the portion located on the inside of the container, and the cross-sectional shape is generally trapezoidal, triangular, or mountain-shaped.

An opening is formed in the front part of the container in Patent Document 3. The front part is provided with an air passage amount adjustment part consisting of a number of angle-adjustable louvers. By adjusting the angle of the louvers, the opening area of the opening can be changed, and the amount of air passing through the opening can be adjusted accordingly.

However, in order to obtain the effects of a drug, it is necessary to direct air containing the drug toward the area where the effect is desired.

However, in the case of Patent Document 1, the front cover section and the rear cover section are composed of numerous flower-shaped motifs connected vertically and horizontally, so it is not possible to control the direction of the flow of air containing the medicine after it has passed through the medicine holder.

In addition, in Patent Document 2, the spaces between the bars on the front side of the container and the spaces between the bars on the rear side of the container are located at the same height, so for example, air that flows between the bars on the front side of the container tends to flow straight through the bars on the rear side of the container, and the direction of the flow of air containing the drug after passing through the drug holder cannot be controlled.

In addition, in Patent Document 3, louvers are provided on the front part, but these louvers are air passage volume adjustment parts for adjusting the amount of air passing through the opening, and are not capable of controlling the direction of the flow of air containing the medicine. In other words, the direction of the air flow is completely different when the amount of air is reduced and when it is increased, and it is not possible to flow air in a targeted manner to a certain area.

The present invention was made in consideration of these points, and its purpose is to control the flow direction so that the air containing the medicine flows toward the desired area.

To achieve the above objective, the present invention provides the container with a wind direction control plate that controls the direction of the airflow blown from outside the container.

The first invention is a chemical diffuser comprising a chemical holder that holds a chemical that is volatile at room temperature, and a container that houses the chemical holder and has air circulation holes, characterized in that a wind direction control plate section that extends in a direction that intersects with the flow of air blown from outside the container is provided in a fixed state to the container.

According to this configuration, air blown from outside the container flows into the container through the air circulation hole and is supplied to the drug holder. In addition, the air that has flowed into the container can be discharged to the outside of the container through another air circulation hole after passing through the drug holder. At this time, when at least a portion of the air blown from outside the container hits the wind direction control plate section, since the wind direction control plate section extends in a direction intersecting the flow of the air blown from outside the container, it becomes possible to control the direction of the air flow by the wind direction control plate section. The air circulation hole can include an air circulation hole for allowing air to flow into the container and an air circulation hole for allowing the air in the container to flow out to the outside.

In addition, because the airflow control plate is fixed to the container, it does not become an airflow control unit that changes angle as in Patent Document 3, but rather allows the airflow direction to be oriented in the desired direction by the airflow control plate.

The second invention is characterized in that multiple airflow control plate sections extending in the same direction are spaced apart from one another.

According to this configuration, air blown from outside the container flows into the container between the multiple air direction control plate sections. In addition, after passing through the drug holder, the air that has flowed into the container can be made to flow out from between the multiple air direction control plate sections when it flows out of the container through another air flow hole. When air passes between adjacent air direction control plate sections, the adjacent air direction control plate sections extend in the same direction, so that the direction of the air flow is along the air direction control plate sections, and the direction of the air flow can be reliably controlled.

The third invention is characterized in that the air flow hole is an inflow air flow hole that allows air to flow into the container from outside the container, and the air direction control plate is provided inside the inflow air flow hole.

With this configuration, when air blown from outside the container flows into the container, the flow can be controlled by the air direction control plate.

The fourth invention is characterized in that the air circulation hole is an outlet air circulation hole that allows air inside the container to flow out to the outside of the container, and the air direction control plate portion is provided inside the outlet air circulation hole.

With this configuration, when the air inside the container flows out to the outside of the container, the flow can be controlled by the air direction control plate.

The fifth invention is characterized in that the airflow control plate includes a first airflow control plate inclined toward the flow of air blown from outside the container, and a second airflow control plate inclined in the opposite direction to the first airflow control plate.

With this configuration, the first airflow direction control plate section and the second airflow direction control plate section are inclined in opposite directions, so that the air containing the medicine can be made to flow in at least two directions, and the effects of the medicine can be obtained over a wide area.

The sixth invention is characterized in that the air flow hole is open in a horizontal direction, the first air flow direction control plate portion is inclined so as to be positioned higher toward the downstream side in the flow direction of the air blown from outside the container, and is disposed on the upper side inside the air flow hole, and the second air flow direction control plate portion is inclined so as to be positioned lower toward the downstream side in the flow direction of the air blown from outside the container, and is disposed on the lower side inside the air flow hole.

With this configuration, the first airflow control plate can guide the air upwards, and the second airflow control plate can guide the air downwards. This allows the air containing the medicine to be diffused both above and below the medicine diffuser, making it possible to obtain the effects of the medicine over a wide area.

The seventh invention is characterized in that the air flow hole opens in a horizontal direction, the first air flow direction control plate portion is inclined so as to be positioned further left in the downstream direction of the flow of air blown from outside the container when viewed from the front of the drug diffuser, and is disposed on the left side inside the air flow hole, and the second air flow direction control plate portion is inclined so as to be positioned further right in the downstream direction of the flow of air blown from outside the container when viewed from the front of the drug diffuser, and is disposed on the right side inside the air flow hole.

With this configuration, the first airflow control plate can guide the air to the left side of the drug diffuser, and the second airflow control plate can guide the air to the right side. This allows the air containing the drug to be diffused to both the left and right sides of the drug diffuser, making it possible to obtain the effects of the drug over a wide area.

The eighth invention is characterized in that the air flow hole opens horizontally, and the air direction control plate portion is inclined so as to be positioned further to the left or right as it approaches the downstream side of the flow direction of the air blown from outside the container when viewed from the front of the drug diffuser.

For example, if the chemical diffuser is hung from a doorknob, the doorknob is located on the right or left side of the door, so the chemical diffuser is installed offset to one side of the door in the left-right direction. On the other hand, the opening that is opened and closed by the door has a width in the left-right direction corresponding to the shape of the door, so if the chemical diffuser is offset to the right, for example, it may be difficult for the chemical to reach the left side of the opening. In the present invention, the airflow control plate is inclined to the left or right, so if the chemical diffuser is offset to the right, for example, by using an airflow control plate inclined to the left, the chemical will reach the left side of the opening. This makes it possible to expand the effective range of the chemical to cover the entire opening.

The ninth invention is characterized in that the drug diffuser is provided with a hanging member for hanging on a door handle.

According to the present invention, a wind direction control plate is provided that extends in a direction that intersects with the flow of air blown from outside the container, so that the flow direction of the air containing the medicine can be controlled so that it flows toward the desired area.

The following describes in detail an embodiment of the present invention with reference to the drawings. Note that the following description of the preferred embodiment is essentially merely an example and is not intended to limit the present invention, its applications, or its uses.

(Embodiment 1)
1 shows a drug diffuser 1 according to a first embodiment of the present invention. The drug diffuser 1 includes a drug holder A, a container 10 for accommodating the drug holder A, and a hanging member 100 for hanging the container 10. The hanging member 100 may be omitted, and in the case where the hanging member 100 is omitted, the container 10 can be used by placing it on a table or desk (not shown).

In the description of this embodiment, the front side of the drug diffuser 1 in use is referred to as the front side, the back side as the back side, the left side when the drug diffuser 1 in use is viewed from the front as the left side of the drug diffuser 1, and the right side as the right side of the drug diffuser 1. Therefore, the width direction of the drug diffuser 1 is the left-right direction. This definition of direction is provided only for convenience of description, and either side may be the right when actually used.

The chemical diffuser 1 is preferably used in windy locations, but can also be used in almost windless locations. When used in windy locations, it is preferable to position the chemical diffuser 1 so that the wind hits the front side of the chemical diffuser 1; in this embodiment, the front side of the chemical diffuser 1 is the upstream side in the air flow direction, and the rear side of the chemical diffuser 1 is the downstream side in the air flow direction. Under natural conditions, the wind direction is not always constant, so the wind may hit the front side of the chemical diffuser 1, or it may hit the rear side, left or right side.

(Configuration of drug carrier A)
The drug support A is made of, for example, a cloth material such as a nonwoven fabric, a net-like material, a sponge-like material, etc., and has breathability in the thickness direction (front-back direction). The drug support A may be, for example, flat, or may be folded to form a pleated shape. The outer shape of the drug support A may be a polygonal shape such as a rectangular or triangular shape, or may be a circular or elliptical shape. A plurality of drug support bodies A can be stored in one container 10. In this case, a plurality of drug support bodies A may be stored stacked in the thickness direction, or may be stored side by side.

The drug support A holds a drug that is volatile at room temperature. The term "volatile at room temperature" refers to the property of volatilizing into the air at room temperature (e.g., 25°C), and examples of such drugs include drugs with a vapor pressure of 0.001 Pa to 0.1 Pa at 25°C. The type of drug is not particularly limited, and examples include insect repellents, insecticides, deodorants, disinfectants, and fragrances, and one or more of these may be used in combination. Specifically, examples of insecticides made of pyrethroid compounds include transfluthrin and metofluthrin, and various optical isomers or geometric isomers exist for these pyrethroid compounds, but any of these isomers can be used, and they can be used alone or in combination of two or more. The drug may also be an ester compound, etc. The above-mentioned drug may be, for example, DEET (N,N-diethyl-3-methylbenzamide), Icaridin (2-(2-hydroxyethyl)-1-piperidine carboxylate 1-methylpropyl), etc. A mixture of the above-mentioned drugs may also be used.

The agent may contain a solvent that dissolves the insecticidal component or the insect repellent component. The agent may also contain a synergist. The agent may also contain an antibacterial agent such as hinokitiol, tetrahydrolinalool, eugenol, citronellal, or allyl isothiocyanate. The agent may also contain a fungicide such as isopropylmethylphenol or orthophenylphenol. The agent may also contain a fragrance or deodorant such as citronella oil, orange oil, lemon oil, lime oil, yuzu oil, lavender oil, peppermint oil, eucalyptus oil, jasmine oil, Japanese cypress oil, cypress oil, bamboo extract, mugwort extract, tung oil, green tea essential oil, or limonene.

The drug can be impregnated into the drug holder A. The amount of drug that volatilizes can be set to about 0.01 to 0.6 mg per hour when the air temperature is 25°C and the flow rate of air blown onto the drug holder A is 0.1 to 1.5 m/sec, but this is just one example and it may be outside this range. The amount of drug that volatilizes can be changed by the type of solvent, the structure of the drug holder A, the material that makes up the drug holder A, the basis weight, etc.

The drug can also be attached to the drug holder A by coating or spraying it, which also allows the drug to be held in the drug holder A. The drug can also be held in the drug holder A by kneading the drug into the material that constitutes the drug holder A. Any method can be used to hold the drug in the drug holder A.

(Configuration of container 10)
The container 10 has a main body 11, a front frame 12, and a rear frame 22. The main body 11, the front frame 12, and the rear frame 22 are molded, for example, from a resin material or the like, and may be molded integrally or may be formed by combining a plurality of members. In this embodiment, the container 10 is configured to be separable into a front portion and a rear portion, but may also be configured to be separable, for example, in the vertical or horizontal direction.

The main body 11 has a rectangular frame shape that is long in the vertical direction. The drug holder A is housed in the main body 11 in a position that extends in the vertical direction. The external shape of the drug holder A and the internal shape of the main body 11 are substantially the same or substantially similar. The drug holder A is present in most of the internal part of the main body 11. The thickness (front-rear dimension) of the main body 11 is substantially equal to the thickness of the drug holder A, or the main body 11 is thicker. If the drug holder A is pleated, the thickness of the drug holder A will be thicker, and the thickness of the main body 11 can be made thicker accordingly. The drug holder A can also be held by the main body 11.

As shown in FIG. 2, the front frame 12 is integrated with the front portion of the main body 11 and has a front upper edge 12a, a front lower edge 12b, a front left side edge 12c, and a front right side edge 12d. The front upper edge 12a extends in the left-right direction along the upper portion of the main body 11. The front lower edge 12b extends in the left-right direction along the lower portion of the main body 11, and the front upper edge 12a and the front lower edge 12b face each other. The front left side edge 12c extends in the up-down direction along the left portion of the main body 11, and the upper end of the front left side edge 12c is connected to the left end of the front upper edge 12a, and the lower end of the front left side edge 12c is connected to the left end of the front lower edge 12b. The front right side edge 12d extends vertically along the right portion of the main body 11, with the upper end of the front right side edge 12d connected to the right end of the front upper side edge 12a and the lower end of the front right side edge 12d connected to the right end of the front lower side edge 12b. This gives the front frame 12 a vertically long rectangular shape like the main body 11, and the front air circulation hole 13 that allows air to circulate inside is formed to open horizontally. The front air circulation hole 13 is an inlet air circulation hole that allows air to flow into the container 10 and is connected to the inside of the main body 11.

As shown in FIG. 3, the rear frame 22 is integrated with the rear portion of the main body 11 and has a rear upper edge 22a, a rear lower edge 22b, a rear left side edge 22c, and a rear right side edge 22d. The rear upper edge 22a extends in the left-right direction along the upper portion of the main body 11. The rear lower edge 22b extends in the left-right direction along the lower portion of the main body 11, and the rear upper edge 22a and the rear lower edge 22b face each other. The rear left side edge 22c extends in the up-down direction along the left portion of the main body 11, and the upper end of the rear left side edge 22c is connected to the left end of the rear upper edge 22a, and the lower end of the rear left side edge 22c is connected to the left end of the rear lower edge 22b. The rear right side edge 22d extends vertically along the right portion of the main body 11, with the upper end of the rear right side edge 22d connected to the right end of the rear upper side edge 22a, and the lower end of the rear right side edge 22d connected to the right end of the rear lower side edge 22b. As a result, the rear frame 12 has a rectangular shape that is long in the vertical direction, similar to the main body 11, and the rear air circulation hole 23 that allows air to circulate inside is formed so as to open in the horizontal direction. The rear air circulation hole 23 communicates with the inside of the main body 11 and is connected to the front air circulation hole 13 through the inside of the main body 11. The rear air circulation hole 23 is an outlet air circulation hole that allows air inside the container 10 to flow out of the container 10. Depending on the wind direction, the outlet air circulation hole may become an inlet air circulation hole, and the inlet air circulation hole may become an outlet air circulation hole.

(Configuration of the rebound suppression plate portion)
As shown in FIG. 1, an upper bounce suppression plate 14 is provided on the upper part of the front frame 12 of the container 10. The upper bounce suppression plate 14 extends toward the inside of the front air circulation hole 13 and is formed so as to approach the upper edge of the front air circulation hole 13 as it moves downstream in the air flow direction. That is, the upper bounce suppression plate 14 extends in the left-right direction along the upper edge of the front air circulation hole 13, and the left end of the upper bounce suppression plate 14 is connected to the upper part of the front left side edge 12c, and the right end of the upper bounce suppression plate 14 is connected to the upper part of the front right side edge 12d. As a result, the upper bounce suppression plate 14 connects the upper part of the front left side edge 12c and the upper part of the front right side edge 12d, which are parts of the front frame 12 that face each other.

As shown in FIG. 5, the upper bounce suppression plate 14 is disposed inside the front frame 12. In each figure, the upstream side of the upper bounce suppression plate 14 in the air flow direction is disposed so as not to protrude outward from the upstream side of the front frame 12 in the air flow direction, but the upstream side of the upper bounce suppression plate 14 in the air flow direction may protrude outward from the upstream side of the front frame 12 in the air flow direction. Also, the downstream side of the upper bounce suppression plate 14 in the air flow direction may or may not protrude into the inside of the main body 11.

As shown in FIG. 1, a lower bounce suppression plate 15 is provided on the lower part of the front frame 12 of the container 10. The lower bounce suppression plate 15 extends toward the inside of the front air circulation hole 13 and is formed so as to approach the lower edge of the front air circulation hole 13 as it moves downstream in the air flow direction. That is, the lower bounce suppression plate 15 extends in the left-right direction along the lower edge of the front air circulation hole 13, and the left end of the lower bounce suppression plate 15 is connected to the lower part of the front left side edge 12c, and the right end of the lower bounce suppression plate 15 is connected to the lower part of the front right side edge 12d. As a result, the lower bounce suppression plate 15 connects the lower part of the front left side edge 12c and the lower part of the front right side edge 12d, which are parts of the front frame 12 that face each other. In this embodiment, the upper bounce suppression plate 14 and the lower bounce suppression plate 15 are provided on the opposing upper edge (one edge) and lower edge (the other edge) of the front air flow hole 13, respectively, but it is also possible to provide only one of them. The lower bounce suppression plate 15 can be vertically symmetrical with the upper bounce suppression plate 14. The inclination angle of the upper bounce suppression plate 14 and the lower bounce suppression plate 15 can be set arbitrarily, but can be set, for example, in the range of 30° to 70° with respect to the vertical plane.

(Configuration of wind direction control plate section)
A plurality of front upper air direction control plate parts (first air direction control plate parts) 16 are provided on the upper side of the front frame part 12 of the container 10. The plurality of front upper air direction control plate parts 16 are provided inside the front air circulation hole 13. The front upper air direction control plate part 16 extends in the left-right direction, which is the direction intersecting with the flow of air blown from the outside of the container 10 (shown by arrow B in FIG. 5). The front upper air direction control plate part 16 is disposed in an area above the vertical center part of the front frame part 12 and below the upper bounce suppression plate part 14. The left end part of the front upper air direction control plate part 16 is integrated with the front left side edge part 12c of the front frame part 12, and the right end part of the front upper air direction control plate part 16 is integrated with the front right side edge part 12d. As a result, the front upper airflow control plate portion 16 is provided continuously from the left end to the right end of the front frame portion 12 and is fixed so as not to move relative to the container 10.

The multiple front upper airflow control plate sections 16 extend in the same direction and are spaced apart from each other in the vertical direction. This allows air to flow between the multiple front upper airflow control plate sections 16. The multiple front upper airflow control plate sections 16 are also inclined so that they are positioned higher the further downstream they are in the airflow direction, and therefore inclined with respect to the flow of air blown from outside the container 10.

The multiple front upper airflow control plate sections 16 face in the same direction as the upper bounce suppression plate section 14. The uppermost front upper airflow control plate section 16 and the upper bounce suppression plate section 14 are arranged with a gap between them in the vertical direction. This allows air to flow between the uppermost front upper airflow control plate section 16 and the upper bounce suppression plate section 14.

A plurality of front lower wind direction control plates (second wind direction control plates) 17 are provided on the lower side of the front frame 12 of the container 10. The plurality of front lower wind direction control plates 17 are provided inside the front air flow holes 13, similar to the front upper wind direction control plate 16, and extend in the left-right direction. The front lower wind direction control plate 17 is disposed in an area below the vertical center of the front frame 12 and above the lower bounce suppression plate 15. The left end of the front lower wind direction control plate 17 is integrated with the front left side edge 12c of the front frame 12, and the right end of the front lower wind direction control plate 17 is integrated with the front right side edge 12d. As a result, the front lower wind direction control plate 17 is provided continuously from the left end to the right end of the front frame 12, and is fixed so as not to move relative to the container 10.

The multiple front lower air direction control plate sections 17 extend in the same direction and are spaced apart from each other in the vertical direction. This allows air to flow between the multiple front lower air direction control plate sections 17. The multiple front lower air direction control plate sections 17 are also inclined so that they are positioned lower the further downstream in the air flow direction, so that the front upper air direction control plate section 16 and the front lower air direction control plate section 17 are inclined in opposite directions.

The multiple front lower air direction control plate sections 17 face in the same direction as the lower bounce suppression plate section 15. The lowest front lower air direction control plate section 17 and the lower bounce suppression plate section 15 are arranged with a gap between them in the vertical direction. This allows air to flow between the lowest front lower air direction control plate section 17 and the lower bounce suppression plate section 15.

The number of front upper air direction control plate sections 16 and the number of front lower air direction control plate sections 17 may be the same or different. Furthermore, the spacing between the multiple front upper air direction control plate sections 16 and the spacing between the multiple front lower air direction control plate sections 17 may be the same or different.

As shown in FIG. 3, an upper end wind direction control plate 24 is provided on the upper part of the rear frame 22 of the container 10. The upper end wind direction control plate 24 extends in the left-right direction and is inclined so that it is located higher as it goes downstream in the air flow direction as shown in FIG. 5. As shown in FIG. 3, the left end of the upper end wind direction control plate 24 is integrated with the rear left side edge 22c of the rear frame 22, and the right end of the upper end wind direction control plate 24 is integrated with the rear right side edge 22d. The upper end wind direction control plate 24 and the upper bounce suppression plate 14 extend in the same direction. The downstream end of the air flow direction of the upper end wind direction control plate 24 is connected to the rear upper edge 22a, and air cannot flow between the upper end wind direction control plate 24 and the rear upper edge 22a.

A lower end wind direction control plate 25 is provided at the bottom of the rear frame 22 of the container 10. The lower end wind direction control plate 25 extends in the left-right direction and is inclined so that it is located lower as it approaches the downstream side in the air flow direction as shown in FIG. 5. As shown in FIG. 3, the left end of the lower end wind direction control plate 25 is integrated with the rear left side edge 22c of the rear frame 22, and the right end of the lower end wind direction control plate 25 is integrated with the rear right side edge 22d. The lower end wind direction control plate 25 and the lower bounce suppression plate 15 extend in the same direction. The downstream end of the air flow direction of the lower end wind direction control plate 25 is connected to the rear lower edge 22b, and air cannot flow between the lower end wind direction control plate 25 and the rear lower edge 22b.

A plurality of rear upper air direction control plates 26 are provided on the upper side of the rear frame 22 of the container 10. The plurality of rear upper air direction control plates 26 are provided inside the rear air circulation holes 23. The rear upper air direction control plates 26 extend in the left-right direction, which is the direction intersecting with the flow of air blown from the outside of the container 10 (indicated by arrow B in FIG. 5). The rear upper air direction control plates 26 are disposed in an area above the vertical center of the rear frame 22 and below the upper end air direction control plate 24. The left end of the rear upper air direction control plate 26 is integrated with the rear left side edge 22c of the rear frame 22, and the right end of the rear upper air direction control plate 26 is integrated with the rear right side edge 22d. As a result, the rear upper air direction control plate 26 is continuously provided from the left end to the right end of the rear frame 22 and is fixed so that it cannot move relative to the container 10.

The multiple rear upper airflow control plate sections 26 extend in the same direction and are spaced apart from each other in the vertical direction. This allows air to flow between the multiple rear upper airflow control plate sections 26. The multiple rear upper airflow control plate sections 26 are also inclined so that they are positioned higher the further downstream they are in the airflow direction, and therefore inclined with respect to the flow of air blown from outside the container 10.

The multiple rear upper air direction control plate sections 26 face in the same direction as the upper end air direction control plate section 24. The uppermost rear upper air direction control plate section 26 and the upper end air direction control plate section 24 are arranged with a gap between them in the vertical direction. This allows air to flow between the uppermost rear upper air direction control plate section 26 and the upper end air direction control plate section 24.

A plurality of rear lower air direction control plates 27 are provided on the lower side of the rear frame 12 of the container 10. The plurality of rear lower air direction control plates 27 are provided inside the rear air circulation holes 23, similar to the rear upper air direction control plate 26, and extend in the left-right direction. The rear lower air direction control plate 27 is disposed in an area below the vertical center of the rear frame 22 and above the lower end air direction control plate 25. The left end of the rear lower air direction control plate 27 is integrated with the rear left side edge 22c of the rear frame 22, and the right end of the rear lower air direction control plate 27 is integrated with the rear right side edge 22d. As a result, the rear lower air direction control plate 27 is provided continuously from the left end to the right end of the rear frame 22, and is fixed so as not to move relative to the container 10.

The multiple rear lower air direction control plate sections 27 extend in the same direction and are spaced apart from each other in the vertical direction. This allows air to flow between the multiple rear lower air direction control plate sections 27. The multiple rear lower air direction control plate sections 27 are also inclined so that they are positioned lower the further downstream in the air flow direction, so that the rear upper air direction control plate section 26 and the rear lower air direction control plate section 27 are inclined in opposite directions.

The multiple rear lower air direction control plate sections 27 face in the same direction as the lower end air direction control plate section 25. The lowest rear lower air direction control plate section 27 and the lower end air direction control plate section 25 are spaced apart in the vertical direction. This allows air to flow between the lowest rear lower air direction control plate section 27 and the lower end air direction control plate section 25.

The number of rear upper airflow control plate sections 26 and the number of rear lower airflow control plate sections 27 may be the same or different. Furthermore, the spacing between the multiple rear upper airflow control plate sections 26 and the spacing between the multiple rear lower airflow control plate sections 27 may be the same or different.

(Configuration of hanging member 100)
The hanging member 100 is composed of, for example, a long member made of a flexible resin material, a string-like member, or the like. The hanging member 100 allows the container 10 to be hung from a door handle, a handrail, or the like. The length of the hanging member 100 can be set as desired, and the length can also be made adjustable. The hanging member 100 may be a member such as a thread or a wire. As shown in FIG. 1 etc., the container 10 may be hung so that its longitudinal direction is in the vertical direction, or, although not shown, the hanging member 100 may be replaced and the container 10 may be hung so that its longitudinal direction is in the horizontal direction.

(Action and Effect)
As described above, according to this embodiment, as shown by the arrow B in Fig. 5, air blown from outside the container 10 flows into the container 10 through the front air flow hole 13 and is supplied to the drug holder A. It is assumed that when a portion of the air blown from outside the container 10 reaches the surface of the drug holder A, it flows so as to bounce off the surface of the drug holder A. The air bouncing off the surface of the drug holder A flows toward the upper edge or lower edge of the front air flow hole 13, and then flows against the flow of the air toward the direction from which the air came in, forming a large vortex.

In contrast, in this embodiment, an upper bounce suppression plate 14 is provided near the edge of the front air flow hole 13, and this upper bounce suppression plate 14 extends toward the inside of the front air flow hole 13 and is formed so that the closer it is to the edge of the front air flow hole 13 the further downstream in the air flow direction it is, the less likely it is to flow in the direction from which the air is flowing in as the air flows toward the upper edge of the front air flow hole 13 hits the upper bounce suppression plate 14. Similarly, the lower bounce suppression plate 15 can suppress the bounce of air flowing toward the lower edge of the front air flow hole 13. This makes it less likely that an airflow will be created that goes against the air flow from the outside of the container 10 toward the front air flow hole 13, so the amount of air passing through the drug holder A can be increased, and the effect of the drug held in the drug holder A can be enhanced.

In addition, when air blown from outside the container 10 hits the front upper airflow control plate 16, the front upper airflow control plate 16 extends so that it is positioned higher the further downstream it is, so the air flows diagonally upwards as shown by arrow C due to the front upper airflow control plate 16. This air flow also flows diagonally upwards because the rear upper airflow control plate 26 extends so that it is positioned higher the further downstream it is.

On the other hand, when air blown from outside the container 10 hits the front lower air direction control plate 17, the front lower air direction control plate 17 extends so that it is positioned lower the further downstream it is, so the air flows diagonally downward as shown by arrow D by the front lower air direction control plate 17. This air flow also flows diagonally downward because the rear lower air direction control plate 27 extends so that it is positioned lower the further downstream it is. By providing the air direction control plates 16, 17, 26, and 27, it is possible to control the flow direction so that the air containing the medicine flows toward the desired area, and it is also possible to widen the range of volatilization of the medicine.

Here, the case where the container 10 of this embodiment is hung from a door handle will be particularly described. In this case, the container 10 is hung from the handle so that the back side of the drug diffuser 1 faces the door. In this way, the wind does not blow on the container 10 from the back side. In other words, the wind can be blown on the container 10 from approximately the front side. The wind blown from the front side is controlled by the wind direction control plate parts 16, 17, 26, and 27, and flows out diagonally upward or downward from the back side of the container 10. This allows the air containing the drug to flow so as to spread in the vertical direction along the surface of the door on which the container 10 is hung. Thus, according to this embodiment, the drug can be diffused over a wide area along the surface of the door, especially when it is hung from a door handle.

In this embodiment, the air direction control plate sections 16, 17, 26, and 27 are provided, but only one of these may be provided. For example, by providing the air direction control plate section 16, the air flow can be directed diagonally upward. All of the air direction control plate sections 16, 17, 26, and 27 may be inclined in the same direction. For example, if all of the air direction control plate sections 16, 17, 26, and 27 are inclined so that they are positioned lower toward the downstream side, the air can be directed diagonally downward. Also, if all of the air direction control plate sections 16, 17, 26, and 27 are inclined so that they are positioned higher toward the downstream side, the air can be directed diagonally upward.

(Embodiment 2)
6 to 12 show a medicine diffuser 1 according to a second embodiment of the present invention. In the second embodiment, the structure of the container 10 and the shape of the airflow direction control plate are different from those in the first embodiment, and other parts are the same as those in the first embodiment. Therefore, the same parts as those in the first embodiment are denoted by the same reference numerals and the description is omitted, and the different parts are described in detail.

In the second embodiment, the container 10 does not include the front frame portion and the rear frame portion of the first embodiment, but the container 10 may include a front frame portion and a rear frame portion. An upper bounce suppression plate portion 14 is provided on the front side of the container 10. Furthermore, a plurality of front air direction control plate portions 30 are provided on the front side of the container 10 below the upper bounce suppression plate portion 14.

The front airflow control plate 30 extends in the left-right direction, which is a direction that intersects with the flow of air blown from outside the container 10. The left end of the front airflow control plate 30 is integrated with the left side of the main body 11, and the right end of the front airflow control plate 30 is integrated with the right side of the main body 11. As a result, the front airflow control plate 30 is provided continuously from the left end to the right end of the main body 11, and is fixed so as not to move relative to the container 10.

The left side portion 30a of each front airflow control plate portion 30 is inclined so that it is positioned higher as it approaches the downstream side of the airflow direction, while the right side portion 30b of each front airflow control plate portion 30 is inclined so that it is positioned lower as it approaches the downstream side of the airflow direction. Therefore, the space between the left side portion 30a and the right side portion 30b of the front airflow control plate portion 30 is twisted.

As shown in FIG. 7, an upper end wind direction control plate portion 24 is provided on the rear side of the container 10. Furthermore, a plurality of rear wind direction control plate portions 31 are provided on the rear side of the container 10 below the upper end wind direction control plate portion 24.

The rear airflow control plate 31 extends in the left-right direction, which is a direction that intersects with the flow of air blown from outside the container 10. The left end of the rear airflow control plate 31 is integrated with the left side of the main body 11, and the right end of the rear airflow control plate 31 is integrated with the right side of the main body 11. As a result, the rear airflow control plate 31 is provided continuously from the left end to the right end of the main body 11, and is fixed so as not to move relative to the container 10.

The right side portion 31a of each rear airflow control plate portion 31 is inclined so that it is positioned lower as it approaches the downstream side of the airflow direction, while the left side portion 31b of each rear airflow control plate portion 31 is inclined so that it is positioned higher as it approaches the downstream side of the airflow direction. Therefore, the space between the right side portion 30a and the left side portion 30b of the rear airflow control plate portion 31 is twisted.

According to this embodiment 2, an upper bounce suppression plate portion 14 is provided near the edge of the front air flow hole 13, so that the bounce of air can be suppressed in the same manner as in embodiment 1. This makes it difficult for an airflow to form against the airflow from the outside of the container 10 toward the front air flow hole 13, so that the amount of air passing through the drug holder A can be increased, and the effect of the drug held in the drug holder A can be improved.

As shown in FIG. 10, when air blown from outside the container 10 hits the left side portion 30a of the front airflow control plate 30, the left side portion 30a extends so that it is positioned higher as it moves downstream, so the air flows diagonally upward (indicated by arrow C) due to the left side portion 30a. This air flow also flows diagonally upward because the left side portion 31b of the rear airflow control plate 31 extends so that it is positioned higher as it moves downstream.

On the other hand, as shown in FIG. 11, when air blown from outside the container 10 hits the right side portion 30b of the front airflow control plate 30, the right side portion 30b extends downward as it moves downstream, causing the air to flow diagonally downward (indicated by arrow D). This air flow also flows diagonally downward because the right side portion 31a of the rear airflow control plate 31 extends downward as it moves downstream. By providing the airflow control plates 30 and 31, it is possible to control the flow direction so that the air containing the medicine flows toward the desired area, and to widen the range of volatilization of the medicine.

(Embodiment 3)
13 to 17 show a medicine diffuser 1 according to a third embodiment of the present invention. In the third embodiment, the structure of the container 10 and the shape of the airflow direction control plate are different from those in the first embodiment, and other parts are the same as those in the first embodiment. Therefore, the same parts as those in the first embodiment are denoted by the same reference numerals and the description is omitted, and the different parts are described in detail.

In the third embodiment, the container 10 is one in which the front frame portion and the rear frame portion of the first embodiment are omitted, but the container 10 may be one that includes a front frame portion and a rear frame portion. An upper bounce suppression plate portion 14 and a lower bounce suppression plate portion 15 are provided on the front side of the container 10. Furthermore, a plurality of front upper wind direction control plate portions 16 and front lower wind direction control plate portions 17 are provided on the front side of the container 10 between the upper bounce suppression plate portion 14 and the lower bounce suppression plate portion 15. Both or one of the front upper wind direction control plate portions 16 and the front lower wind direction control plate portions 17 may be omitted. The front upper wind direction control plate portion 16 and the front lower wind direction control plate portion 17 may be inclined in the same direction.

As shown in Figs. 14 and 16, a plurality of right-side wind direction control plate sections 32 and a plurality of left-side wind direction control plate sections 33 are provided on the rear side of the container 10. The right-side wind direction control plate section (second wind direction control plate section) 32 extends in the vertical direction, which is the direction intersecting the flow of air blown from the outside of the container 10. The upper end of the right-side wind direction control plate section 32 is integrated with the upper part of the main body section 11, and the lower end of the right-side wind direction control plate section 32 is integrated with the lower part of the main body section 11. As a result, the right-side wind direction control plate section 32 is continuously provided from the upper end to the lower end of the main body section 11, and is fixed so as not to move relative to the container 10. The right-side wind direction control plate section 32 is inclined so as to be located further to the right as it moves downstream in the air flow direction. The multiple right-side wind direction control plate sections 32 are provided at intervals from each other in the left-right direction.

The left side wind direction control plate portion (first wind direction control plate portion) 33 extends in the vertical direction, which is the direction intersecting with the flow of air blown from the outside of the container 10. The upper end of the left side wind direction control plate portion 33 is integrated with the upper part of the main body portion 11, and the lower end of the left side wind direction control plate portion 33 is integrated with the lower part of the main body portion 11. As a result, the left side wind direction control plate portion 33 is continuously provided from the upper end to the lower end of the main body portion 11, and is fixed so as not to move relative to the container 10. The left side wind direction control plate portion 33 is inclined so as to be located further left as it goes downstream in the air flow direction. The multiple left side wind direction control plate portions 33 are provided at intervals from each other in the horizontal direction. In this example, the number of left side wind direction control plate portions 33 is greater than the number of right side wind direction control plate portions 32, but they may be the same, or the number of right side wind direction control plate portions 32 may be greater. In addition, either the right side airflow direction control plate 32 or the left side airflow direction control plate 33 may be omitted.

The right-side airflow direction control plate 32A, located at the far left, and the left-side airflow direction control plate 33A, located at the far right, are connected to each other at their upstream ends in the air flow direction, so that air cannot flow between the right-side airflow direction control plate 32A and the left-side airflow direction control plate 33A.

Figure 17 shows the state of use of the drug diffuser 1 according to the third embodiment. In this example, the drug diffuser 1 is hung from the door knob (handle) 202 of the door 200. Since the door knob 202 is provided on the right (or left) side of the door 200, the drug diffuser 1 is installed in a state of being offset to one side in the left-right direction of the door 200. On the other hand, the opening 201a of the frame 201 that is opened and closed by the door 200 has a width in the left-right direction corresponding to the shape of the door 200, so if the drug diffuser 1 is offset, for example, to the right, it may be difficult for the drug to reach the left side of the opening 201a. In this embodiment, since the left air direction control plate portion 33A is inclined to the left, even if the drug diffuser 1 is offset, for example, to the right, the drug can also reach the left side of the opening 201a (the direction in which the drug flows is indicated by arrow E). This allows the effective range of the drug to be expanded to cover the entire opening 201a.

(Embodiment 4)

At the upper left corner of the front side of the container 10, an upper left bounce suppression plate 46 is provided. The upper left bounce suppression plate 46 is inclined so that it is located more to the upper left as it moves downstream in the air flow direction. At the upper right corner of the front side of the container 10, an upper right bounce suppression plate 47 is provided. The upper right bounce suppression plate 47 is inclined so that it is located more to the upper right as it moves downstream in the air flow direction. At the lower left corner of the front side of the container 10, a lower left bounce suppression plate 48 is provided. The lower left bounce suppression plate 48 is inclined so that it is located more to the lower left as it moves downstream in the air flow direction.

In the upper right region of the front of the container 10, multiple upper right air direction control plate sections 43 are provided at intervals. The upper right air direction control plate section 43 is inclined so that it is located more to the upper right as it moves downstream in the air flow direction. In the lower left region of the front of the container 10, multiple lower left air direction control plate sections 44 are provided at intervals. The lower left air direction control plate section 44 is inclined so that it is located more to the lower left as it moves downstream in the air flow direction. In the lower right region of the front of the container 10, multiple lower right air direction control plate sections 45 are provided at intervals. The lower right air direction control plate section 45 is inclined so that it is located more to the lower right as it moves downstream in the air flow direction.

As shown in FIG. 19, the rear side of the container 10 is provided with a vertical plate portion 50 extending vertically in the center of the left-right direction, and a horizontal plate portion 51 extending horizontally in the center of the left-right direction. The vertical plate portion 50 and the horizontal plate portion 51 divide the inside of the rear air circulation hole 23 into four regions.

In the upper left area of the rear of the container 10, multiple upper left air direction control plate sections 52 are provided at intervals. The upper left air direction control plate section 52 is inclined so that it is located more to the upper left as it moves downstream in the air flow direction. In the upper right area of the rear of the container 10, multiple upper right air direction control plate sections 53 are provided at intervals.

According to the fourth embodiment, the rebound suppression plate portions 46 to 49 can suppress the rebound of air in the same manner as in the first embodiment. This makes it difficult for an airflow to form against the airflow from the outside of the container 10 toward the front air flow hole 13, so the amount of air passing through the drug holder A can be increased, and the effect of the drug held in the drug holder A can be improved.

In addition, the airflow control plates 42-45 and 52-55 allow the air containing the medicine to flow to the upper left, upper right, lower left, and lower right, expanding the range of effectiveness of the medicine.

(Embodiment 5)
20 to 22 show a medicine diffuser 1 according to a fifth embodiment of the present invention. In the fifth embodiment, the structure of the container 10 is different from that of the first embodiment, and other parts are the same as those of the first embodiment. Therefore, the same parts as those of the first embodiment are denoted by the same reference numerals and the description thereof is omitted, and the different parts are described in detail.

In the third embodiment, the container 10 is one in which the front frame portion and rear frame portion of the first embodiment are omitted, but the container 10 may be one that includes a front frame portion and a rear frame portion. An upper bounce suppression plate portion 14 and a lower bounce suppression plate portion 15 are provided on the front side of the container 10. Furthermore, a plurality of front upper wind direction control plate portions 16 and front lower wind direction control plate portions 17 are provided on the front side of the container 10 between the upper bounce suppression plate portion 14 and the lower bounce suppression plate portion 15. The front upper wind direction control plate portion 16 and the front lower wind direction control plate portion 17 may be inclined in the same direction.

A blocking plate 70 is provided on the rear side of the container 10. The blocking plate 70 prevents air from flowing out to the rear side of the container 10, but a small through hole may be formed in the blocking plate 70. On the other hand, as shown in FIG. 20, an air vent (air flow hole) 60 is provided in the upper wall of the container 10, and an air vent (air flow hole) 61 is provided in the right wall of the container 10. As shown in FIG. 22, an air vent (air flow hole) 61 is also provided in the left wall of the container 10, and an air vent (air flow hole) 62 is also provided in the lower wall of the container 10.

Therefore, in the case of embodiment 5, air that flows into the inside of container 10 from the front side of container 10 flows out upward, to the side, and downward from air vents 60, 61, and 62, respectively. This allows air containing the drug to flow over a wide area, thereby expanding the range of effectiveness of the drug.

In the fifth embodiment, only one of the front upper airflow control plate 16 and the front lower airflow control plate 17 may be provided, or the airflow control plate extending in the vertical direction may be provided with an inclination to one side in the left-right direction.
