Description

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

Conventionally, methods for exterminating pests and microorganisms on tatami mats include drying the tatami mats by exposing them to sunlight and drying them, and spraying or coating insecticides on the tatami mats. In either case, the outer surface of the tatami mat is simply treated, but the inner layer remains untreated, and a satisfactory pest control effect cannot be expected.

The present invention allows housewives and others to dispose of tatami mats in each household safely and efficiently with a high degree of pest control effect, and also allows them to be stored safely and in a compact structure when not in use. The purpose of this invention is to provide an injection device for treating tatami mats. An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is an aerosol injector for injecting a tatami treatment agent, and a release valve (not shown) is opened by pressing down a valve lever 3 via a push button 2 against a restoring spring (not shown). is opened, and the aerosol can be injected from the spout 2a of the push button 2 via the valve lever 3 and the passage inside the push button 2. The structure of the injector 1 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 an intermittent injection type as seen in metered injections. It may be an injection type.

Reference numeral 4 denotes a double-tube type protective cap fixed to the head of the injector 1, and the protective cap 4 has an opening 4a on the top surface for operating the push button 2 and an injector in the inner cylindrical part. It has an opening 4b for inserting the cylinder 2b, and the opening 4b is vertically elongated to allow vertical movement of the injection cylinder 2b as the push button 2 is pressed down.

Reference numeral 5 denotes a connecting member that connects the injection tube 2b of the push button (2) and the injection needle for tatami insertion described in detail below. Opening 4 of the outer cylinder that is connected and fixed and has a protective cap 4 at the tip.
A fixed cylinder 5a protruding outward from c, a rotating cylinder 5b pivotally connected to the tip of the fixed cylinder 5a so as to be rotatable from a horizontally extending state to a drooping bent state, and the rotating cylinder 5b. It consists of a flexible conduit 5c connected to the tip of 5b. The pivot connecting portion 5d of the fixed cylinder 5a and the rotating cylinder 5b constitutes a switching valve, and this switching valve is
The passages 5a' and 5b' of a and 5b are communicated when in the horizontally extended state, and are blocked when in the drooping and bent state. With such a configuration, even if the push button 2 is pressed down by mistake, the aerosol will not be sprayed unless the rotary cylinder 5a is horizontally extended.
It can prevent accidental injection. As shown in the enlarged view of FIG. 4, the passage 5a' of the fixed cylinder 5a is directly connected to the nozzle 5b1 on the front side of the rotary cylinder 5b at the base end of the rotary cylinder 5b when it is in the hanging and bent _state . short circuit passage 5b ₂
If this short circuit path _5b2 and the nozzle 5 are formed,
This is convenient because normal injection can be performed through _b1 .
The opening 4c of the outer cylinder of the protective cap 4 is connected to the push button 2.
The opening is vertically long to allow vertical movement of the rotary cylinder 5a as the rotary cylinder 5a is pressed down. 4d is a canopy-like wall formed along the periphery of the opening 4c to prevent dust from adhering during storage; 5c' is a coiled portion formed in the middle of the flexible conduit 5c;
c can expand and contract in the coiled portion 5c'.

Reference numeral 6 denotes an injection needle for inserting the tatami mat attached to the tip of the flexible conduit 5c of the connecting member 5, and the material of the injection needle 6;
The shape is not particularly limited as long as it can be inserted into the tatami, but
Usually, a metal tubular body with a thickness that does not leave marks on the tatami mat is used, and the tip is blind and one or more injection holes 6a are installed on the side, preferably at different levels. It is formed. The diameter of the nozzle hole 6a is usually in the range of about 0.25 to 1.0 mm. The injection needle 6 has
A protection tube 6b can be provided as shown in the figure,
This protection tube 6b has a length that can accommodate the injection needle 6 over its entire length, and when inserted into the tatami mat, it is pushed up from the tatami surface and the notches 6b' and 6b' on both sides open. , has a structure that allows its length to be reduced. 6c is a knob that also serves as a holder for the injection needle 6.

7 is a housing portion for the injection needle 6;
is provided either on the body of the injector 1 or on its protective cap 4. The figure shows a case where the storage section 7 is provided in the protective cap 4, and the storage section 7 is
The protection cap 4 has a hole 7b for inserting the injection needle 6 formed on the bottom of the recessed step 7a on the top surface, and protrusions 7c, 7c on both sides of the hole 7b. When inserted, the knob 6 attached to the injection needle 6
The structure is such that holes 6c', 6c' on the lower surface of c are fitted into protrusions 7c, 7c. It is convenient for packaging if the top surface of the knob 6c and the top surface of the protective cap 4 are substantially flush with each other in this fitted state. In addition, the storage section 7 is provided with a cross section at the bottom of the protective cap 4, as schematically shown in FIG.
A mold flange 4e is provided, and a hole 4 in the upper surface of the flange 4e is provided.
The injection needle 6 may be inserted and fixed to f. In the figure, 4g is an engagement step.

Figure 1 shows the situation when the device of the present invention is not in use.
In this state when not in use, the injection needle 6 is housed in the protective cap 4 and is completely isolated from the outside, so there is no danger of accidentally touching the injection needle 6 with your fingers. In addition, since the rotating cylinder 5b is bent in the hanging direction, it is not bulky, and the device can be stored safely and with a compact structure.

When performing pest control or other treatment on tatami mats, the injection needle 6 is pulled out from the protective cap 4 as shown in FIG. 2 from the state shown in FIG.
As shown in FIG. 6, after inserting the aerosol into the tatami mat a, the push button 2 is operated to inject the aerosol into the tatami mat a through the injection needles 6, thereby allowing the tatami mat a to be subjected to a predetermined treatment.

In this way, in the device of the present invention, the aerosol for tatami treatment can be directly injected into the tatami mat a through the injection needle 6 provided in the injector 1, and this injected treatment agent can be applied to the wide inner layer of the tatami mat. Since it permeates and diffuses over a wide area, by performing this type of injection operation over one or several areas of the tatami, the entire inner layer of the tatami can be treated uniformly, resulting in an extremely high pest control effect. . Furthermore, since the injection needle 6 is pre-equipped on the injector 1, there is no need to attach the injection needle 6 to the injector 1, and after inserting the injection needle 6 into the tatami mat a, press the push button The tatami process can be carried out with extremely simple operations, and this type of tatami process can be carried out easily at home. Furthermore, when not in use, the flexibility of the conduit 6c is used to
Since the injection needle 6 can be stored in the storage part 7 of the protective cap 4, even though the injection needle 1 is equipped with the injection needle 6, it can be stored safely and with a compact structure. , convenient for storage and transportation.

In the present invention, the tip of the flexible conduit 5c can be branched into a plurality of branches as shown in FIG. 7, and each of the branched pipes _5c1 ... may be provided with an injection needle 6. .

Further, as shown in FIG. 8, the push button 2 is provided with a plurality of, for example, three, injection cylinders (not shown), and an injection needle 6 is connected to each of the injection cylinders via a connecting member 5. In this way, the treatment agent can be injected from three places on the tatami at once, improving work efficiency.

Furthermore, the tip of the injection needle 6 may be branched into a plurality of parts as shown in FIGS. 9 and 10.
