  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. 1 shows an air purification filter of this example, FIG. 2 shows an air purification filter of another example, FIG. 3 shows how the air purification filter of this example is attached to an automobile, and FIG. A) is a cross-sectional view of the air purification filter of this example, and FIG. 4B is a cross-sectional view of a common type air purification filter according to another example of the embodiment of the present invention. FIG. 5 shows a common type air purification filter according to an example of another embodiment of the present invention.

  The common type air purification filter 1 of this example is of the form as shown in FIG. 1 (A), and houses the filtration part 2a in the frame 3 in the same manner as the conventional air purification filter. It has the formed filter body 2.

The air purification filter 1 of this example is for an automobile and is used by being attached to an air purification apparatus mounted on the automobile. As shown in FIG. 3 (B), for example, it is attached to the filter mounting portion X in the dashboard, and as shown in FIG. 3 (A), the outside air taken into the vehicle and the air circulating in the vehicle are allowed to pass through. Can do.
The air purification filter 1 according to the present invention is not limited to the automobile as in this example, but can be used for various applications including general air conditioning.

The filter part 2a of the filter body 2 is a sheet-like body made of paper or non-woven fabric, and can collect and purify dust contained in the air by allowing air to pass through. In the frame 3, it is coordinated in a wavy shape as shown in FIG.
The filter part 2a can use the material conventionally used for the air purification filter as it is. Moreover, it is good also as what gave the deodorizing function by mix | blending activated carbon etc.

  The frame 3 of the filter body 2 has a substantially rectangular outer peripheral shape provided around the filtration portion 2a, and is made of a thin plate such as cardboard, a plastic plate, or a hard nonwoven fabric, or around the filtration portion 2a. Is a portion hardened by resin. In this example, the planar view is rectangular, and the filtration part 2a is arranged inside, but the outer peripheral shape is a trapezoid or rhombus, for example, the front side has a dimension in the front and back direction rather than the back side. Implementation in various forms, such as increasing the size, is possible.

  The formation of the frame body 3 is not essential. For example, the frame body 3 may be omitted when the shape of the filter body 2 can be maintained by the rigidity of the filtration part 2a itself. Further, as shown in FIG. 1 (B), the elasticity of the filtration part 2a in the direction folded in a wave shape is used to attach the air purification filter 1 to the filter attachment part X. The frame body 3 may be omitted for use with the adjustment member 4 or in place of the adjustment member 4.

  Here, in what is shown in FIG. 1 (A), a tongue-like handle 31 is provided so as to protrude from the outer surface of the frame 3, and the air purification filter 1 can be replaced by pinching this handle 31. Although the work can be easily performed, the formation of the handle 31 is not essential. Moreover, it is good also as what provided the hole which can hook a finger | toe on the frame 3. FIG.

  An adjustment member 4 is attached around the filter body 2, that is, outside the side wall of the frame body 3. In the present example, the filter body 2 is a sponge-like body in which the adjustment member 4 is attached to the outside of the three side walls on the back side and the both sides on the three sides of the filter body 2. The adjusting member 4 has a thickness t of 8 mm to 50 mm in the inner and outer directions in an uncompressed state. In this example, 18 mm is used. In addition, said thickness means the state in the state which was filled with air, and is in an uncompressed state, when using an air tube thing as mentioned later.

The adjustment member 4 may be provided as a set that is not attached to the filter body 2 at the time of sale, and that the user attaches to the filter body 2 at the time of use. Specifically, it sells in the state which stuck easy-release tapes, such as a double-sided tape, on the surface of the adjustment member 4. FIG. The adjustment member 4 at this time has a thickness in the inner and outer directions according to the gap between the filter attachment portion X and the filter body 2 when attached to the filter body 2.
On the contrary, the adjustment member 4 may be attached to the filter body 2 at the time of sale, and the user may be able to remove it from the filter body 2 at the time of use. In addition, when the adjustment member 4 is completely removed from the filter body 2, there is a possibility that the adhesion to the filter mounting portion X becomes poor and air leakage may occur. It is desirable that the material is made of a stretchable material and can maintain close contact. By selling and using the air purification filter 1 in such a form, it is possible to cover the various filter attachment portions X more flexibly.

  Moreover, as shown in FIG. 2, it is good also as that to which the adjustment member 4 was attached to all the outer sides of the side wall of the frame 3. By doing so, the filtration part 2a can always be positioned at the center of the air purification filter 1 regardless of the compression degree of the adjustment member 4.

  When the air purification filter 1 is attached to the filter attachment portion X, the adjustment member 4 is formed between the filter attachment portion X and the frame body 3 of the filter body 2 as indicated by an arrow in FIG. It is compressed and deformed according to the gap. It is desirable that the adjusting member 4 is such that the filtering portion 2a is not deformed even in a compressed state. Thereby, even if the size of the filter mounting portion X is different, the gap between the filter mounting portion X and the filter body 2 is filled by the adjusting member 4, so that the air purification filter 1 is attached to the filter mounting portion X. It can be held securely. In other words, the air purification filter 1 can be attached to the filter mounting portion X whose size is between the outer dimensions of the filter body 2 and the outer dimensions including the adjustment member 4. Various filter attachment portions X can be covered by the compression allowance of the member 4. The adjusting member 4 has functions such as a sealing function (preventing air leakage) and the prevention of abnormal noise caused by contact with the filter mounting portion X.

  Further, for example, as in the invention described in Patent Document 2, when the filter body 2 itself is not deformed when being attached to the filter attachment portion X, air filtration in the filter body 2 is stably performed. It is also possible to have the effect of being made.

  Various materials can be used as the adjusting member 4 as long as the material can be easily deformed by compression. Specific examples include those having elasticity and compressible in the thickness direction, such as sponge, sponge rubber, urethane, urethane rubber, and urethane foam. Further, the adjustment member 4 may be an air tube-shaped member whose dimensions can be adjusted by adjusting the amount of air to be filled. Further, the adjustment member 4 may or may not have air permeability. However, in the case of using a material having air permeability, in order to sufficiently exert the filtration function of the filtration part 2a of the filter body 2, the adjustment member is made of a material having a larger ventilation resistance than the filtration part 2a. It is desirable from the viewpoint of the function of the filter that air should flow preferentially to the filtering part 2a rather than 4.

  Note that a hard material that does not deform may be used as the adjustment member 4. Specific examples include foamed resins (such as polystyrene foam and foam rubber), other synthetic resins, and paper. In this case, since the deformation due to the compression is not performed, the dimension adjustment is performed by cutting off a part of the adjustment member 4 or superposing a plurality of adjustment members 4. In the former case, specifically, a cut line is printed on the surface in advance, or a perforation or a concave groove is provided. This dimensional adjustment by cutting is applicable even when a material that is easily deformed by compression is used as described above.

  Here, the filter attachment portion X includes one for attaching an air purification filter whose front and back dimensions are 18 mm, and one for attaching an air purification filter having a size of 27 mm. The one shown in FIG. 4B can be used for any of them. This is such that the dimension of the filter body 2 in the front and back direction is 18 mm, and the same dimension of the adjustment member 4 is 27 mm, and the adjustment member 4 protrudes upward in the figure from the filter body 2. ing.

  Thereby, in the filter mounting part X for 18 mm, the portion of the adjustment member 4 that protrudes upward in the figure is deformed so as to fall down as indicated by the arrow in FIG. Coordinated. In addition, in the filter mounting portion X for 27 mm, the air purification filter 1 is arranged without the adjustment member 4 being deformed in the front and back direction. In either case, it is possible to hold the position of the filter body 2 in the filter attachment portion X.

  In the example shown in FIG. 4B, the lower ends of the filter body 2 and the adjustment member 4 are aligned, and the adjustment member 4 protrudes upward in the drawing from the frame body 3. However, the form when the same dimension of the adjustment member 4 is formed larger than the dimension of the front and back direction of the filter body 2 is not limited to this, and the adjustment member 4 is in the front and back direction of the filter body 2. It may be protruding in both.

  Next, other embodiments will be described. In FIG. 5, the planar view is rectangular, and the adjustment member 4 is L-shaped on the two adjacent outer sides of the side walls of the frame 3, which are the two adjacent sides of the filter body 2. It is attached so as to exhibit. In the case of this example, the adjusting member 4 having an inner and outer thickness t of 36 mm is used. In this case, each of the filter bodies 2 and the adjustment member 4 combined to form a unit filter member 1a, and a plurality of the unit filter members 1a are overlapped in the front and back direction to form a set of air. The purification filter 1 is used. Then, the unit filter member 1a on one side and the adjustment unit filter member 1a on the other side are overlapped with each other by 180 °.

  In this example, the size of the unit filter member 1a in the front and back direction is 9 mm, and the two unit filter members 1a can be overlapped as shown in the drawing to correspond to the filter mounting portion X for 18 mm. Although not shown, when the three unit filter members 1a are overlapped, the filter mounting portion X for 27 mm can be handled. As described above, the unit filter members 1a can be attached to the filter attachment portion X having various front and back dimensions by appropriately overlapping the unit filter members 1a.

  In addition, as described above, the adjustment members 4 arranged in an L shape are alternately arranged, so that the adjustment members 4 are arranged in four directions in a state where the unit filter members 1a are overlapped. Thus, as shown in FIG. 5 (B), a region through which air can pass is formed in the central portion of the unit filter member 1a in the plan view. Since air can be passed through the central portion in this way, uniform air filtration is possible.

  Further, as shown in FIG. 5B, only the adjustment member 4 overlaps with the two corners in the state where the unit filter member 1a is overlapped, so that it does not pass through the filtration part 2a at all. The amount of air that passes only through the adjustment member 4 can be minimized.

  By adopting each of the embodiments described above, the common type air purification filter 1 according to the present invention is applied to a filter mounting portion X for attaching 30 to 50 types of air purification filters for automobiles that currently exist. It was possible to cope with much fewer kinds.
