Description

[Detailed description of the invention] [Field of industrial application] The present invention is a brush device for exterminating pests, which is mainly used to exterminate pests that live on animal hair, etc. while brushing dogs, cats, and other pet animals. It is related to.

[Conventional technology]

To exterminate pests such as fleas and lice that are parasitic on the animal hair or skin of pets, generally, after spraying the insecticide from a sprayer filled with insecticide toward the animal's fur, This was done by brushing.

However, in conventional pest control work, a sprayer filled with insecticide and a brush are configured separately, so the sprayer and brush must be replaced alternately, which requires a lot of work. There were problems in that it required time and effort, and the replacement work itself was extremely troublesome.

Therefore, for example, in the brush device for exterminating pests described in Japanese Utility Model Publication No. 40-33003, the grip part that is held by hand is hollow and a chemical solution is stored inside.
By implanting flexible needles, that is, brushes, each having a penetrating pore into the lower surface of the gripping portion, the brush and the drug solution storage container are integrated. In this case, by pressing the upper surface of the gripping part with the palm of the hand, the liquid medicine is discharged through the pores of the brush.

[The problem that the idea aims to solve]

However, in the brush device for pest control described above, the discharge path for the chemical solution is formed by the pores of the brush, so for example, this can easily become clogged and the discharge path becomes obstructed. It is difficult for the chemical solution to come out through the pores of the brush that is in contact with the animal's skin, and it is easier for the drug solution to come out from areas that are not in contact with the animal's skin, making the discharge condition of the drug solution unstable, and as a result, uneven treatment is likely to occur. This is causing problems.

[Means to solve the problem]

In order to solve the above-mentioned problems, the pest extermination brush device of the present invention has a brush part consisting of numerous flexible needles formed on a molded head body connected to a brush handle part shaped like a hollow sealed container. A chemical liquid passage opening is provided in a part of the brush planting surface of the brush portion, and a chemical liquid discharge port of a discharge pipe capable of discharging the chemical liquid from the brush handle is located close to this opening. It is characterized by what it does.

[Effect]

According to the above configuration, the chemical liquid from the brush handle is guided through the discharge pipe to the chemical liquid discharge port of the discharge pipe, and the chemical liquid passage opening on the brush installation surface is located close to the chemical liquid discharge port. The liquid is sprayed between flexible needles (hereinafter referred to as brushes) installed on the brush installation surface. in this case,
For example, even when the brush tip is in close contact with the animal's skin surface during brushing, a space is secured between the brush implantation surface and the animal's skin, and the medicinal solution discharge path is not blocked, resulting in stable delivery. The discharge state is maintained.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

As shown in FIGS. 2 and 3, the brush device for pest control in this embodiment is roughly divided into a brush handle part A for holding the brush and a brush part B for rubbing animal hair. It is configured.

As shown in FIG. 1, the brush handle A has the structure of a hollow airtight container 1 having a closed space cross section. Inside this container 1, there is a chemical solution (insecticide) for exterminating pests that parasitize pets, etc.
2 and a pressure gas 3 such as LPG, chlorofluorocarbon gas, or carbon dioxide gas.

A housing 4 serving as a valve mechanism is provided at the center of the upper end of the container 1, and a deep tube 5 with one end of the liquid suction port facing the inner bottom of the container 1 is provided at the lower end opening of the housing 4. The ends are connected. The housing 4 is further provided with an orifice-shaped vapor tap 6 for sucking pressure gas on its lower wall, while a gasket 7 is airtightly provided on its upper opening to close the inside of the housing 4 and close the valve seat. It is configured to function as

The stem 8 provided inside the housing 4 is
An orifice-shaped suction hole 10 supported in an upwardly biased state by a spring 9 and provided in the peripheral wall of the stem 8 is connected to an outlet passage 11 inside the stem 8.
The suction hole 10 of the stem 8, which is normally located in the upper limit region due to the bias of the spring 9, is closed by the inward end of the gasket 7. The upper end of the stem 8 projects further upwards than the gasket 7, and a discharge pipe 12 is connected to the open end thereof. A discharge passage 13 that communicates with the discharge passage 11 of the stem 8 is formed through the inside of the discharge pipe 12, and an operation button for an operation button passive is formed on the outer periphery of the discharge pipe 12. A portion 14 is formed.

On the other hand, a base cylinder 15 is fitted to the upper end wall of the container 1 described above so as to surround the outer periphery of the protruding portion of the stem 8, and a metal ring 16 is fitted from the inside thereof and is fastened and fixed. A hollow head molded body 17 is further screwed onto the outer periphery of the upper half of the base cylinder 15 so as to cover the head of the container 1.

The front surface of the tip of the head molded body 17 is formed as a brush planting surface inclined at an angle that facilitates brushing when the brush handle A is gripped,
A brush portion B is constituted by a countless number of flexible needles (brushes) 18... being planted on this brush planting surface. In addition, a chemical liquid passage opening 19 is formed in a part of the brush planting surface, in this embodiment, in an approximately central area, and the above-mentioned discharge pipe 12 is connected to this chemical liquid passage opening 19. The chemical liquid discharge ports 13a are configured to be close to each other and face each other.

An operation button opening 20 is formed at the rear of the head molded body 17, and the rear part of the operation button 21 fitted into the operation button opening 20 projects slightly outward. This operation button 21 is made of a flexible material, and a pair of left and right bifurcated legs 22 formed at the bottom thereof are inserted into the holes of the head molded body 17.
The operation button 21 is attached to the head molded body 17 by being locked with the lower end claw part 23 of the leg part 22. Further, the operating protrusion 24 formed extending in front of the operation button 21 has a bifurcated shape extending to both sides of the discharge pipe 12. The operation driven part 14
can be pushed downward.

In the pest extermination brush with the above configuration, first grasp the brush handle A and direct the brush surface toward the fur of the pet animal, then press the operation button 21 to discharge the medicinal solution from the tip of the discharge tube 12. Brush part B
The chemical solution passage opening 1 on the brush planting surface in
Brush 18 while spraying through 9 in a spray form.
By scraping the group hair with ..., pests infesting animal hair, skin, etc. are exterminated.

The principle of ejecting the above-mentioned chemical liquid will be explained as follows. When the operation button 21 is pressed with a finger, the base of the leg section 22 of the operation button 21 is elastically bent, so that the operating protrusion 24 pushes down the operation driven section 14 of the discharge pipe 12.

The discharge pipe 12 is integrated with the stem 8 and has a spring 9.
When the stem 8 moves downward against the accumulated force, the suction hole 10 of the stem 8 is displaced and released from the gasket 7, and the suction hole 10 becomes open (the state shown in FIG. 1).

As a result, the chemical liquid whose liquid surface is pressurized by the pressure gas filled in the container 1 is sucked into the housing 4 through the deep tube 5, and at the same time, the pressure gas is sucked through the vapor tap 6 of the housing 4. The chemical solution and the pressure gas are diffused and mixed inside the housing 4 to form fine particles. These particles are guided to the outlet passage 11 through the suction hole 10 of the stem 8 in the open state, and are further discharged in the form of a spray from the medical solution outlet 13a at the tip of the discharge passage 13 of the discharge pipe 12 that communicates with the outlet passage 11. be done.

The atomized chemical liquid fine particles ejected from the discharge pipe 12 are ejected from the chemical liquid passage opening 19 on the brush-installed surface of the head molded body 17 through between the brushes 18 .

As explained above, in the above embodiment,
A chemical liquid passage opening 19 is provided in a part of the brush installation surface of the brush part B, and between the brushes 18, that is,
Since the medicinal solution is sprayed through the opening 19 into the space secured between the animal's skin and the brush installation surface, for example, when brushing, the brush 1
8... Even when the tip is in close contact with the animal's skin surface, unlike the conventional pest extermination brush described above, the medicinal liquid discharge path is not blocked, and a stable discharge condition is maintained, Processing unevenness that has occurred is reduced.

In addition, in the above-mentioned conventional brush device for exterminating pests, as described above, by pushing the top surface of the grip part held by hand with the palm of the hand, the chemical solution is discharged through the pores of the brush, In this case, it is difficult to perform accurate operations with the movement of the palm, it is difficult to discharge the medicinal liquid as desired during brushing, and spontaneous leakage is likely to occur even when you only want to brush. Requires extra work to drain the chemical solution; Discharge of the chemical solution can only be performed when the chemical solution is located below the air space within the container; orientation is restricted; etc. This resulted in additional problems.

However, in the above embodiment, the stem 8 provided at one end serves as the drug solution storage container.
A structure is used in which a medicinal liquid is injected through the stem 8 when an insertion operation is caused, and the operation driven part 14 is connected to the container to cause a push-in action of the stem 8. The opening 19 is configured to guide the medicinal liquid injected from the tip of the stem 8 to the medicinal liquid passage opening 19. In this case, the operation driven part 14 can be operated with a fingertip that can freely move, such as an index finger, in the hand that is gripping the container. Therefore, it is possible to accurately perform the ejection operation of the medicinal liquid as necessary while performing the brushing operation, with almost no effect on the gripping state of the entire container. As a result of this structure, which has excellent operability and controllability of chemical liquid injection, for example,
Brushing while spraying less frequently on the ventral side where there are fewer hairs than on the back side where there are more hairs, or brushing only without spraying the chemical solution, and then interrupting the work. It is possible to continuously perform this treatment over the entire body of the animal. Therefore, convenience in use and work efficiency are improved.

In the above embodiment, the discharge pipe 12 and the head molded body 17 are constructed separately, but the structure is not limited to this. For example, the discharge pipe 12 and the head molded body 17 may be formed integrally, or the stem 8 The operation driven part 14 for producing a pressing action is attached to the head molded body 17.
and is configured to be movable relative to the container 1 side, and configured to discharge the medicinal liquid by directly pushing down the operation driven part 14 with a finger through an opening in the side of the head molded body 17. You can also do that. Therefore, the presence or absence of the operation button 21 for operating the stem 8 does not specifically matter. Further, it is also possible to configure the discharge pipe 12 and the stem 8 by integrally molding them.

Further, the inside of the container 1 is filled with pressure gas, and the pressure gas and the chemical solution are diffused and mixed by the valve component including the housing 4, the stem 8, the gasket 7, and other members, and the mixture is made into fine particles and sprayed. Although the structure is shown in which the liquid medicine is discharged in a shape, the present invention is not limited to this structure. For example, by pushing down the stem 8, a fixed amount of the chemical liquid may be directly injected from the discharge pipe. Furthermore, although the chemical liquid spraying structure of the illustrated embodiment is used with the brush handle A in an upright position, this structure is just one embodiment and is compatible with the brush device of the present invention. Rather, in view of the fact that the brush handle A is often used with the brush handle A placed sideways or supported upside down, the chemical solution is maintained in the same manner as when it is supported upright in any situation. It is desirable to adopt a structure that can be injected from the discharge pipe 12.
For example, as shown in Japanese Unexamined Patent Publication No. 59-169561, by using a flexible tube as the deep tube 5 and adopting the structure of an aerosol spray can with a weight attached to the tip, the above-mentioned results can be achieved. It is possible to achieve the objective, and also by other conventional techniques. Therefore, the specific structure of the chemical liquid spray structure is not questioned at all.

The chemical solution passage opening 19 formed in the brush portion B may be formed at an arbitrary position on the periphery side of the brush planting surface, for example, in addition to the approximately central position of the brush planting surface in the above embodiment. It is possible to form.

[Effect of idea]

As described above, the brush device for exterminating pests of the present invention has a brush portion consisting of numerous flexible needles formed on the head molded body connected to the brush handle portion in the shape of a hollow hermetically sealed container. A chemical liquid passage opening is provided in a part of the brush planting surface, and a chemical liquid discharge port of a discharge pipe capable of discharging the chemical liquid from the brush handle is located close to this opening. be.

Therefore, the injection path is not blocked, which occurs in conventional pest control brush devices, and the chemical solution is stably ejected through the chemical solution passage opening on the brush installation surface. As a result, it is possible to eliminate processing unevenness that has conventionally occurred.
