Description

[Detailed explanation of the idea] The present invention relates to an injection device for treating tatami mats.

Conventionally, as a method to exterminate pests and microorganisms on tatami,
Commonly used methods include drying the tatami, especially the back side of the tatami, in the sunlight, and spraying or applying insecticides to the tatami, but in either case, in any case, the outer surface of the tatami is simply Even though it is treated, the inner layer remains untreated, and in this case, a completely satisfactory pest control effect cannot be expected.

The purpose of this invention is to provide an injection device that can perform the treatment of tatami mats with a high degree of pest control effect and with extremely simple operation. The embodiment will be described below based on the accompanying drawings.

In the figure, 1 is an aerosol injector for injecting a tatami treatment agent, and by pushing down the valve rod 3 against a restoring spring (not shown), a discharge valve (not shown) is opened and the aerosol is injected. I'm starting to be able to do it. The structure of such an injector itself is essentially the same as that of a normal aerosol injector used to exterminate flies, cockroaches, etc., and it is not only a continuous injection type but also a continuous injection type as seen in metered injection. It may be an injection type.

Reference numeral 3 denotes an actuating member provided at the upper end of the valve rod 2 of the injector 1, and wing portions 31, 3 protruding laterally at the lower end.
I have 1.

Reference numeral 4 denotes an injection needle for inserting tatami mats which is fixed upright at the upper end of the operating member 3, and the base end of the injection needle 4 is connected to an injection passage 3 provided in the operating member 3 and extending in the vertical direction.
It is connected to the upper end of the valve rod 2 through the valve rod 2, and receives aerosol supply from the valve rod 2. The material and shape of the injection needle 4 are not particularly limited as long as it can penetrate into the tatami mat, but usually a metal tubular body with a thickness that does not leave puncture marks on the tatami mat is used. The length is also arbitrary; for example, when applied to standard tatami mats (about 5 cm thick), the protrusion length is preferably around 4 cm. Further, the formation position, number and shape of the injection holes 41 formed in the injection needle 4 are also arbitrary. The case is shown in which they are formed at three locations on the side of the screen in multiple stages vertically, with a phase shift of 120° at each stage. Although the illustrated one is of a side injection type, a vertical injection type may be used instead, and in this case, a nozzle hole is formed at the tip of the injection needle 4. This type is advantageous when the treatment agent is injected from the side of the tatami mat. The shape of the nozzle hole 41 may be a horizontally or vertically long slit shape or a cross shape in order to obtain wide diffusivity.
It is preferable that the diameter of the injection hole 41 is approximately equal to or slightly smaller than the inner diameter of the injection needle 4.
Further, the main body portion of the injection needle 4 may be stretchable or bendable (including one having a rubber tube in the middle).

Reference numeral 5 denotes a spring 51 which is mounted on the upper part of the body part 11 of the injector 1 so as to cover the periphery of the injection needle 4, and is movable up and down and always maintains the upward movement position.
It is a protective cap that is biased and has a through hole 53 in the top surface 52 for the outward protrusion of the injection needle 4.

Reference numeral 6 denotes a stopper installed below the operating member, and the stopper 6 comes into contact with the operating member 3 and prevents it from being pushed down while the protective cap 5 is being pushed down and the injection needle 4 is being projected outward. However, after the outward protrusion operation is completed, it is removed from the actuating member 3, and
Make it possible to press down. Such a stopper 6 is removably provided below the actuating member 3, and normally prevents the actuating member 3 from being pressed down, but if it is removed, the actuating member 3
The structure may be such that it can be pushed down, or it may be fixedly provided below the actuating member 3, and when the actuating member 3 is at a predetermined rotational position, it can be pushed down. The structure may be such that it is prevented from being lowered and is allowed to be pushed down when it is in another rotational position; the latter case is shown in the figure.

The stopper 6 shown in the figure is annular and has a high point 61 and a low point 32, which prevents the actuating member 3 from being depressed when it coincides with the high point 61, while from this position the actuating member 3 is rotated so that it coincides with the low point 62, the structure is such that it can be pushed down.

In order to perform such a rotational operation of the actuating member 3 from outside the protective cap 5, the outer ends of the wing parts 31, 31 of the actuating member 3 are inserted into the longitudinal slit 55 of the body part 54 of the cap 5. The rotary operation part 33 is provided at the end of the protrusion. The vertical slit 55 is located on the top surface 52 of the protective cap.
It extends to the upper part of the body 54 of the protective cap so as not to prevent the injection needle 4 from fully protruding.

When the device of the present invention having the above-mentioned configuration is not in use, the protective cap 5 biased by the spring 51 maintains the upward movement position and functions as a protective cap for the injection needle 4, as shown in FIG. Therefore, even though the injection needle 4 is provided, the injection needle 4 can be safely transported and stored without the risk of injury to the human body.

On the other hand, when performing pest control or other treatment on tatami mats using the device of the present invention, the injector 1 is pushed down while the top surface 52 of the protective cap 5 is pressed against the tatami surface a, as shown in FIG. As this is pushed down, the injector 1 and thus the injection needle 4 move forward toward the tatami mat a, and the injection needle 4 passes through the through hole 53 in the top surface 52 of the protective cap and is inserted into the tatami mat a. During this operation of inserting the injection needle 4 into the tatami mat a, the actuating member 3 is positioned above the high point 61 of the stopper 6 and is prevented from being pushed down, as is clear from FIGS. 1 and 5. Therefore, the operation of inserting the injection needle 4 into the tatami mat a can be carried out without any trouble without involving the injection of aerosol.

Next, as shown in FIG. 5, after inserting the injection needle 4 into the tatami mat a, when the injector 1 is rotated 90 degrees, the stopper 6 fixed to the injector 1 also moves 90 degrees. degree rotational displacement, the lower part 62 of the actuating member 3 coincides with the actuating member 3 as shown by the imaginary line in FIG.
When the injector 1 is further pushed down from this state, the valve lever 2 is pushed down via the protective cap 4 and the actuating member 3, and the aerosol (tatami treatment agent) is released. is from injector 1 to injection needle 4
It is injected into the tatami mat a through the tatami mat. After a predetermined amount of aerosol has been injected into the tatami mat a, when the pressure on the injector 1 is released, the valve lever 2 is restored to its original position by the restoring spring, and the aerosol injection stops. Next, when the injector 1 is pulled up and the injection needle 4 is removed from the tatami mat a, the protective cap 5 is restored to its original position by the action of the spring 51. By turning and displacing the device, it becomes the state shown in FIG. 1, and is ready for the next operation.

As described above, according to the device of the present invention, the tatami treatment agent can be directly injected into the inner layer of the tatami, and the injected treatment agent permeates and diffuses over a wide range of the inner layer of the tatami. By carrying out the application at one or several locations on the tatami mat, the entire inner layer of the tatami mat can be uniformly treated and an extremely high pest control effect can be obtained.
What's more, this kind of treatment can not only be carried out with the tatami still on the floor, but also with extremely simple operations such as inserting an injection needle into the tatami and spraying the treatment agent, making it extremely easy to treat tatami at home. It has the advantage of being very easy to perform. Furthermore, although the device of the present invention is equipped with an injection needle, the injection needle is usually protected by a protective cap, so there is no risk of injury to the human body due to inadvertent contact with the injection needle, which improves safety. Are better.

In the present invention, the chemicals used for treating the tatami mats include at least one of the various chemicals normally used for this type of application, mixed appropriately.
