Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jetting delay device, and particularly to a jetting operation of a container content (for example, an insecticide or a disinfectant) in a closed chamber after a predetermined time has passed from the jetting operation. The latter relates to a jet delay device that continuously holds the state.

Generally, in a container of a type in which insecticides, disinfectants, etc. are jetted in a sealed room or the like, a predetermined time difference is given from the time of the jetting operation of the user to the start of the actual jetting operation, during which the user I try to get out of the room.

When a function for delaying the ejection of contents is added, the convenience of the ejection operation by the user is ensured, the construction of the apparatus itself is simplified, and the delay time is expanded. It is desirable to increase the spray range, and the present invention meets this demand.

[0004]

9 and 10 are explanatory views showing a conventional ejection delay device (Japanese Patent Laid-Open No. 9-150874). FIG. 9 shows the jet delay device when it is stationary, and FIG. 10 shows the jet delay device when it is operating.

In these figures, 31 is a case body,
32 is a container installed in the case body 31, 33 is a container 32
Is a coil spring for urging the valve upward, 34 is a stem provided with a valve portion (not shown), 35 is a nozzle fitted to the stem 34, 35a is a plurality of ribs erected under the nozzle, and 36 is a case body. 31 is a lid, 36a is a water injection recess formed in the upper surface of the lid 36, 36b is a through hole formed in the water injection recess 36a, 36c is a nozzle insertion hole formed in the center of the upper surface of the lid 36, and 37 is A support frame fitted to the upper end side of the container 32, 38 is a water injection recess 36a and a support frame 3
7 shows a water-absorbing and softening tubular cylindrical body, respectively.

When the stem 34 is pushed down with respect to the container 32, its valve portion is switched from the closed state to the open state, and the contents of the container 32 are ejected from the tip portion of the nozzle 35 into the external space.

In the stationary state of FIG. 9, the container 32 is pushed down by the porous body 38 in a rigid state whose upper surface is suppressed by the lid 36. This is because the porous body 38 is a hard one having a shape-retaining property at all times, that is, in a state of not absorbing water.

At this time, the container 32 moves downward as shown in the figure against the urging force of the coil spring 33 in the state where the container 32 becomes a so-called one body, and the valve portion of the stem 32 remains closed. .

In order to obtain the operating state shown in FIG. 10, the user may pour water into the stationary water injection recess 36a shown in FIG.

Water that has been poured into the water-filling recess 36a is through-hole 36.
It moves downward from b and enters the porous body 38 to soften the porous body.

As the degree of softening progresses, the biasing force of the coil spring 33 becomes stronger than the shape retaining force of the porous body itself. Therefore, the container 32 moves upward by the biasing force while the porous body 38 is compressed toward the lid 36.

In this movement, from the start of movement to the time when the rib 35a of the nozzle 35 comes into contact with the back surface of the lid 36, the container 32 and the stem 34 are integrally lifted without changing their relative positions. Therefore, the valve portion of the stem 34 remains closed, and when the rib 35a of the nozzle 35 comes into contact with the back surface portion of the lid 36, the stem 34 stops, and thereafter, the container 32 and the support frame 37 are in the stopped state. Since it rises with respect to the stem 34, the valve portion of the stem 34 is opened, and the contents of the container 32 are ejected from the tip portion of the nozzle 35, and the operation state (ejection continuation state) of FIG. 9 is entered.

In the jet delay device of FIGS. 9 and 10, from the end of the jetting operation in which the user has poured water into the water injection recess 36a of FIG. 9, the softening action of the porous body 38 that has absorbed water causes the container 32 to And the stem 34 and the nozzle 35 rise to move the rib 35 of the nozzle.
The time is delayed until a comes into contact with the back surface of the lid 36 and immediately after that, the ejection operation is started.

[0014]

In the case of the conventional delayed jetting device, the user has to prepare water for pouring into the water injection concave portion, so that there is a problem in that the convenience of the delayed jetting operation is poor. It was

Further, as the mechanism for ejecting the contents, since a constituent element such as a porous body or a coil spring (for lifting the container itself accommodating the contents) which is not originally necessary is used, a delayed ejection device is constructed. There were problems that the number of parts increased and the cost increased, and the manufacturing and assembly process became complicated.

Therefore, in the present invention, due to the improvement of the components used as the ejection mechanism of the contents, the container itself is kept fixed, and the user does not have to prepare anything different from the ejection mechanism. An object of the present invention is to enable the jetting operation to be improved in convenience at the time of operation, and to suppress the increase in the number of parts of the delayed jetting device and the complication of the manufacturing / assembling process.

Another object of the present invention is to widen the ejection area of the contents by making the ejection surface of the output side hole a slant surface having a predetermined angle.

Another object is to secure a more sufficient delay time for the user by adding a component for extending the delay time from the end of the ejection operation to the start of the actual ejection operation.

[0019]

The present invention solves this problem as follows. (1) In a jet delay device that starts a jetting operation of the contents of a container after a lapse of a predetermined time from a jetting operation and continuously holds the state after the jetting operation, an output side hole portion for jetting is provided, and A valve member that moves downward due to a jetting operation and moves upward due to the pressure of the contents, an inner cylindrical portion for accommodating the contents, and an outer sheath provided with a hole for outside air.

The pressure of the contents flowing into the inner tubular portion through the valve member causes the valve member to move to the outside air hole.
When the outside air is sucked into the space portion of the outer sheath-shaped portion from the above portion and moved upward by a predetermined length with respect to the cover member at the predetermined position, it is opened from the closed state until then. The state is switched to a state in which the inside of the container and the output-side hole are communicated with each other. (2) In the above (1), the valve member is replaced by the valve mechanism.
And a space for inhaling the outside air.
The above-mentioned valve action part

An intake adjustment member is provided on the input side of the outside air hole for adjusting the degree of intake of outside air.

According to the present invention, first, the valve member, the cover member and the stem are moved downward by the ejection operation of the user, and the cover member is held at a predetermined position so that the stem and the inside of the container are separated from each other. The valve member is brought into the communicating state, and thereafter, the valve member moves upward with respect to the cover member in the stopped state, and the new valve mechanism is opened, so that the contents are ejected. Therefore, the delayed jetting operation can be simply performed by pressing, and the number of parts of the delayed jetting device can be reduced and the manufacturing / assembling process can be simplified.

Further, as described in (1) and (2) above, the valve portion

In the present specification, the "skirt portion" means that the lower side is wider in the radial direction than the upper side, and the "reverse skirt portion" is that the upper side is wider in the radial direction than the lower side. It shows the surrounding surface.

Further, the upstream side of the contents (the side of the container body 14) is "lower" and the downstream side of the contents (the side of the output side hole 2a of the valve member 1) is "upper".

Here, the cylindrical hanging portion 3 and the sheath-like response portion 4
Are tightly fitted to each other at the tapered step portion 3b,
The entire valve member 1 composed of and is integrated.

The inner cylindrical portion 6 and the stem 10 are tightly fitted to each other by the trumpet-shaped portion 6f, and the cover member 5 (inner cylindrical portion 6, outer sheath portion 7) and the entire stem 10 are also integrated.

In the valve member 1, the protruding portion 2b of the hat-shaped portion 2 abuts on the outer peripheral surface of the inner tubular portion 6 over, for example, one round thereof, and the skirt portion 2d and the inverted skirt portion 2e of the hat-shaped portion 2 are
Each end of the outer sheath 7 is in close contact with the inner peripheral surface of the outer sheath 7 over the entire circumference thereof (in the case of FIGS. 1 and 2), and the end of the skirt portion 3a of the cylindrical hanging portion 3 is the inner cylindrical portion 6
The large diameter portion 6a of the inner peripheral surface of the inner peripheral surface of the inner peripheral surface of the inner cylindrical portion 6a is closely contacted with the large diameter portion 6a of the inner cylindrical portion 6a.
It is in close contact with the small-diameter portion 6b of the inner peripheral surface over the entire circumference.

The cover member 5 includes the protruding portion 7 of the outer sheath portion 7.
b is in contact with the inner peripheral surface of the cylindrical portion 15a of the cover body 15.

Therefore, the cover member 5 (the inner tubular portion 6
The outer sheath-shaped portion 7) and the outer sheath-shaped portion 7) are movable as a unit while being guided by the cylindrical portion 15a of the cover body 15.

When the lateral hole portion 10b of the stem 10 is opened, the valve member 1 (the hat-shaped portion 2, the cylindrical hanging portion 3 and the sheath-like responsive portion 4) flows into the sheath-like responsive portion 4 by the contents. Under the pressure of, the cover member 5 is integrally guided and moves upward.

The order in which the contents contained in the container body 14 reach the output side hole 2a of the valve member 1 is roughly as follows: the input side hole 12a of the housing 12 and the inner peripheral surface of the housing 12 and the stem 10. Gap between outer peripheral surface Transverse hole 10b of stem 10 Passage 10a of stem 10 Hole 6e of inner tubular portion 6 Space 6g for storage of inner tubular portion 6 (internal space 4e of sheath-like response portion 4) Sheath The gap between the skirt portion 4c of the state-responsive portion 4 and the large-diameter portion 6a of the inner peripheral surface of the inner tubular portion 6 is the groove portion 4b of the sheath-like response portion 4 and the space portion 3c of the tubular hanging portion 3.

In the stationary state of FIG. 1, the stem 10 is urged upward by the action of the coil spring 12b and stabilized at the position shown in the drawing. The stem rubber 11 is the opening portion of the stem 10 on the upstream side of the lateral hole portion 10b. The protruding portion 7b of the outer sheath 7 is located above the engaging protrusion 15b of the tubular portion 15a, and the valve member 1 has an opening-side end portion of the sheath response portion 4. 4d is in contact with the lower step portion 6d of the inner tubular portion 6 (the skirt portion 4c of the sheath-shaped response portion 4 is a small-diameter portion 6b of the inner peripheral surface of the inner tubular portion 6).
And the end portions of the skirt portion 2d and the reverse skirt portion 2e of the hat-shaped portion 2 are in close contact with the inner peripheral surface of the outer sheath-shaped portion 7), and the protruding portion 16a of the cap 16 and the cover body 15 It is in a state of being engaged with the protruding portion 15c.

At this time, since the above-mentioned and the above portions of the ejection path of the contents are not secured, it goes without saying that the contents in the container body 14 do not flow to the output side hole 2a of the valve member 1.

In order to eject the contents, the user may remove the cap 16 from the cover body 15 and press, for example, the upper surface portion of the valve member 1 (the peripheral portion of the output side hole 2a of the hat-shaped portion 2). . The cap 16 and the cover body 1
The reference numeral 5 is made of synthetic resin, and the removal work can be easily performed.

With this pressing operation, (1) valve member 1
(The hat-shaped portion 2, the cylindrical hanging portion 3 and the sheath-shaped response portion 4) and the cover member 5 (the inner cylindrical portion 6 and the outer sheath-shaped portion 7) integrally move downward, and (2) inside The stem 10 integrated with the tubular portion 6 also moves downward and the stem rubber 11 is deformed as shown in FIG. 2, whereby the upstream opening portion of the lateral hole portion 10b of the stem 10 is opened, and (3 ) The cover member 5 that has moved downward is provided with the protruding portion 7b of the outer sheath-shaped portion 7.
Is positioned below the protruding portion 15b of the cylindrical portion 15a and is in engagement with the protruding portion 15b. In addition, the outer sheath portion 7 and the tubular portion 1
5a is made of synthetic resin, and the protruding portion 7b is the cylindrical portion 1
It is ensured that the protrusion 5b of 5a moves downward and is held there.

As a result, the above-mentioned portion of the content jetting path is secured, and the content passes through the passage 10a of the stem 10 and the hole 6e of the inner cylindrical portion 6 into the internal space 4e of the sheath-like response portion 4. Inflow (see Figure 2).

Due to the pressure of the inflowing contents, the end portion of the skirt portion 4c of the sheath-like response portion 4 (the engagement between the protruding portion 7b of the outer sheath-shaped portion 7 and the protruding portion 15c of the tubular portion 15a). For the sake of matching, the inner cylindrical portion 6 does not move upward) but moves upward while keeping close contact with the small diameter portion 6b of the inner peripheral surface of the inner tubular portion 6.

In this movement, while the skirt portion 4c of the sheath-like response portion 4 and the small-diameter portion 6b of the inner tubular portion 6 continue to be in close contact with each other, the above portion of the content ejection path cannot be secured, so that the sheath-like response portion The contents that have flowed into the internal space 4e of the portion 4 or the storage space portion 6g (see FIG. 3) of the inner tubular portion 6 do not proceed to the groove portion 4b of the sheath-like response portion 4.

Time has elapsed from the pressing operation by the user,
After the time when the end of the skirt portion 4c of the sheath-shaped response portion 4 moves from the small diameter portion 6b of the inner tubular portion 6 to the slope portion 6c, the above portion is secured, that is, to the output side hole portion 2a. The entire content ejection path is formed (see FIG. 3).

The upward movement of the sheath-shaped response portion 4 with respect to the inner tubular portion 6 is caused by the protrusion 2b formed on the inner peripheral surface of the hat-shaped portion 2 which interlocks with the inner tubular portion 6. It continues until it engages with the protrusion 6h (see FIG. 3).

In this way, the ejection operation is delayed by the time from the start of the pressing operation until the above portion of the content ejection path is secured.

The delay time depends on the shape, size and weight of the valve member 1, the degree of close contact between the valve member 1 and the cover member 5, the vertical length of the small diameter portion 6b of the inner tubular portion 6, and the sheath shape. A desired value can be set by adjusting the shape and size of the response unit 4.

The outer peripheral surface of the inner tubular portion 6 and the outer sheath portion 7,
In the space portion 7d between the ceiling surface portion 2c of the hat-shaped portion 2,
The external air is inhaled in accordance with the upward movement of the sheath-shaped response portion 4 to increase the delay time.

That is, as an object to be lifted up by the pressure of the contents, the outer sheath-shaped part 7 is added in addition to the sheath-shaped responding part 4 and the inner cylindrical part 6 which are directly related to the formation of the above-mentioned contents ejection path. As a result, the resistance component when the inflow content (pressure), which is a so-called drive source for the delayed ejection operation, increases, and the movement speed of the sheath-like response portion 4 is reduced.

The intake path of the outside air is roughly the gap between the slit-shaped portion 7a of the outer sheath-shaped portion 7-the inner peripheral surface of the cylindrical portion 15a and the outer peripheral surface of the outer-sheath-shaped portion 7-the upstream side step of the bush 9. Part 9b-
Groove 9a of Bush 9-Downstream Step 9c of Bush 9-
The space portion 8e of the suction member 8 is the suction hole portion 8c of the suction member 8.

The suction member 8 is fitted into the tubular portion 7e of the outer sheath 7 in such a manner that it is pushed in from below.

The inhalation member 8 in the fitted state has the collar portion 8 thereof.
While a is in contact with the lower end of the tubular portion 7e, its ceiling portion 8b creates a gap space 7h between the ceiling portion 8b and the bottom surface (outside air hole portion 7c) of the outer sheath portion 7.

A bush 9 is fitted into the suction member 8 by being pushed in from below, and the upper surface of the bush 9 (following the downstream step 9c) is located on the rear edge side of the ceiling portion 8b of the suction member 8. Is in contact with the bench-shaped step portion 8d.

By providing the bush 9 in the suction member 8, dust and the like in the suctioned outside air are prevented from entering the space portion 7d for sucking outside air, and the degree of suction of outside air can be adjusted, for example, per unit time. The outside air intake is adjusted so that it is reduced.

That is, by decreasing the increase rate of the pressure in the space 7d, the end of the skirt portion 4c of the sheath-like response portion 4 set to the state of FIG. The delay time until the jetting operation start state of No. 3 is started is lengthened.

If this adjustment function is not taken into consideration, a filter may be provided in the suction member 8.

As shown in FIG. 3, the end portion of the skirt portion 4c of the sheath-shaped response portion 4 has a small diameter portion 6b on the inner peripheral surface of the inner tubular portion 6.
From the large-diameter portion 6a to about the same timing,
The end portion of the inverted skirt portion 2e of the hat-shaped portion 2 also moves from the small-diameter portion 7g of the inner peripheral surface of the outer sheath-shaped portion 7 to the large-diameter portion 7f, and the contact end portion and the contact inner peripheral surface do not contact with each other. It becomes a state.

This is because when the valve member 1 tries to start the ejection operation, the resistance of the valve member (to the upward movement) is reduced to some extent to secure the above-mentioned content ejection path. This is to shorten the transient time of and to sharpen the ejection start operation of the contents.

As described above, according to the present invention, first, the valve member, the cover member and the stem are moved downward by the jetting operation of the user, and the cover member is held at a predetermined position to keep the inside of the stem and the container. Since the valve member moves upward with respect to the cover member in the stopped state and the new valve mechanism is opened so that the contents are ejected, the delayed ejection operation is performed. By simply pressing, it is possible to reduce the number of parts of the delayed ejection device and to simplify the manufacturing / assembly process.

Further, since the ejection surface of the output side hole is an inclined surface, the content ejected from the output side hole is shaken at this angle, so that the content is straight above the output side hole. As compared with the case of injecting into, the extent to which the injecting performance is affected by the settling particles after injecting and the floor surface is wetted can be reduced.

Since the valve member and the cover member in the stopped state form a space for sucking the outside air in response to the subsequent upward movement of the valve member that has once moved downward due to the ejection operation, The delay time from the end of the jetting operation to the start of the jetting operation, that is, the time until the valve member moves upward to open the valve mechanism can be made longer.

Further, since the dust removing member is provided on the input side of the space portion for sucking the outside air, it is possible to prevent foreign matter from entering the outside space portion.

Further, since the suction adjusting member on the input side of the space portion for sucking the outside air is provided, a more optimal delay time can be secured.
