Description

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

Technical background of the invention and its problems Conventionally, as a method for exterminating pests and microorganisms on tatami,
Commonly used methods include drying the tatami, especially the back side of the tatami, in sunlight, and spraying or applying insecticides to the tatami, but in both cases, the outer surface of the tatami is simply treated. However, the inner layer remains untreated, and a satisfactory control effect cannot be expected.

Purpose of the invention The present invention enables the treatment of tatami mats to be carried out with a high degree of pest control effect and with an extremely simple operation. It can be used for spraying in narrow spaces such as between a chest of drawers and a wall, between a chest of drawers and a chest of drawers, or under the floor.It is also safe when not in use, and there is no risk of losing powder to parts. The purpose of this invention is to provide an injection device for treating tatami mats that can be stored.

Structure of the invention The present invention provides an aerosol injector for spraying treated tatami mats, which is equipped with a protective cap on the head, and a tatami mat that is appropriately connected to the injection part of the injector at the connection part at the base end to receive aerosol supply. A tatami treatment characterized in that the protective cap is provided with an injection needle for insertion, and a holder portion for holding the injection needle is formed in the protective cap so that the main body of the injection needle is stored in the cap. related to the injection device.

Embodiment of the invention An embodiment of the invention will be described below based on the accompanying drawings.

In the figure, 1 is an aerosol injector of a tatami treatment injector equipped with a protective cap 5 on the head, and a valve lever 3 is pushed via a push button 2 against a restoring spring (not shown). By lowering it, a discharge valve (not shown) is opened and the aerosol can be sprayed. The structure of such an injector itself is virtually no different from a normal aerosol injector used to exterminate flies, cockroaches, etc.
Not only a continuous injection type but also a continuous injection type as seen in metered injection may be used. Further, the structure may be such that the injection operation can be performed with the protective cap 5 provided.

Reference numeral 4 denotes an injection needle for inserting tatami mats, which is connected to the injection part of the injector 1 at the base end connecting part 4a, and its material and shape may be particularly selected as long as it can be inserted into the tatami mats. There is no particular limitation, and usually a metal tubular body with a thickness that does not leave marks on the tatami mat is used. The effective length is also arbitrary; for example, when applied to standard tatami mats (5 cm thick), around 4 cm is appropriate. The injection needle 4 may be extendable or bendable. The formation position, number, shape, and opening area of the injection holes 4b provided in the injection needle 4 are also not particularly limited. It is formed in multiple stages vertically, with the phase being shifted by 120° in each stage. Although the illustrated one is of a side injection type, a vertical injection type may be used instead, and in this case, the injection hole is formed at the upper end 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 4b may be a horizontally long or vertically long slit-like cross shape in order to obtain wide diffusion. In addition, as the connection part 4a provided at the base end of the injection needle 4, the injector 1
The figure shows a case where the insertion port _4a1 is formed with an inner diameter corresponding to the outer diameter of the valve rod 3, and in this case, the valve rod 3 is connected to the push button 2. After removing it, it is inserted into the insertion port _4a1 and connected. Instead of such a connection means, the push button 2 may be directly inserted into the connecting part 4a so that the injection hole 2a of the push button 2 and the inside of the injection needle 4 are connected without removing the push button 2. Alternatively, if the push button 2 has a nozzle (not shown) as seen in conventionally known externally operated devices, the nozzle may be connected by being inserted into the connecting portion 4a. Further, the connecting portion 4a and the injection portion of the injector 1 may be connected using a flexible tube (not shown).

A holder portion 7 for holding the injection needle 4 is formed in the protective cap 5 so that the main body portion of the injection needle 4 is housed within the cap 4 as shown in FIG. The holder part 7 shown in the figure is composed of a recessed step 7a formed in a part of the outer periphery of the top plate part 5a of the protective cap 5, and an insertion hole 7b formed in the bottom surface of the recessed step 7a. By inserting the main body of the injection needle 4 into the protective cap 5 through the insertion hole 7b, the injection needle 4 can be held in the holder 7.

The injection needle 4 can be formed in the top plate part 5a of the protective cap 5, preferably in the center thereof, and an insertion part 6 into which the injection needle 4 can be removably inserted at the connecting part 4a at the base end thereof. The insertion part 6 may have a structure in which an insertion hole is formed on the upper surface of the top plate part 5a and the connection part 4a is inserted into the insertion hole as shown in the figure, or it can be constructed in the opposite manner. Although not shown in the figure, a protrusion is formed on the upper surface of the top plate portion 5a,
It may have a structure in which the connecting portion 4a is inserted into the insertion hole _4a1 , or may have a structure other than the above. Such an attachment may be a loose fit so that the attachment can be easily uncoupled when necessary. If such an insertion portion 6 is formed in the protective cap 5, it is convenient because the protective cap 5 can also be used as a member for inserting the injection needle 4 into the tatami mat a. This state of use is shown in FIG.

In the device of the present invention having the above-described structure, when not in use, the injection needle 4 is held in the holder portion 7 of the protective cap 5, as shown in FIG.
In this holding state, the main body of the injection needle 4, that is, the part that may pierce the human body, is stored in the protective cap 5.

In the state shown in FIG. 1, the injection needle 4 is removed from the injection part of the injector 1, and the injection part is completely free from the injection needle 4. 1 can be used as a normal injector for aerial injection.

On the other hand, when performing pest extermination or other treatment on tatami mats using the device of the present invention, the injection needle 4 is removed from the holder part 7 of the protective cap 5 and inserted into the surface of the tatami mat a, and the base end of the injection needle 4 is connection part 4a
The injection part of the injector 4, for example, the valve rod 3, is connected to the injector 4, and the tatami treatment agent is injected into the layer of tatami a through the injector 1 and the injection needle 4. The situation during this injection operation is shown in FIG. The tatami treatment agent injected into the tatami layer in this manner diffuses (permeates) within the layer and exhibits a predetermined medicinal effect, thereby achieving the purpose of the tatami treatment.

After completing the injection operation, disconnect the injector 1 and the injection needle 4, then remove the injection needle 4 from the tatami mat a, and then hold it in the holder part 7 of the protective cap 5 to perform the next operation. be prepared for operations.

Effects of the invention As described above, the device of the present invention can be used not only for tatami treatment but also for ordinary aerial spraying and spraying into narrow spaces. The injected treatment agent permeates and diffuses over a wide range of the inner layer of the tatami, so by performing this injection operation on one or several tatami areas, the entire inner layer of the tatami can be completely covered. It can be treated uniformly and has extremely high pest control effects. Moreover, it has the advantage that such a treatment can not only be carried out while the tatami is being laid, but also by extremely simple operations such as inserting an injection needle into the tatami and spraying a treatment agent. Furthermore, since the injection needle 4 can be held in the holder part 7 of the protective cap 5 when not in use, there is no risk of the injection needle 4 being lost as a part during storage, and this In the held state, the injection needle main body, which is at risk of piercing the human body, is stored in the protective cap 5, so it has the advantage of being able to be stored safely.
