Description

[Detailed Description of the Invention] The present invention relates to a foaming chemical spraying device that is effective for exterminating pests and removing bad odors from garbage dumps.

To exterminate pests, such as termites that eat away at the flooring and pillars of houses, it is best to spray the chemical evenly over the flooring and pillars, and to make the condition last as long as possible.

To exterminate pests such as cockroaches, it is also a good idea to spray chemicals in similar conditions on their spawning sites and passageways.

It is also best to treat plants in greenhouses in the same way, and the same can be said for spraying chemicals to remove bad odors from garbage dumps, etc.

Therefore, as a way to spread the drug in such a state, it is considered to spray the drug in the form of foam, and various spraying devices for this purpose have been devised.

However, with conventional spraying devices, the weight of the device itself is large, and the direction of spraying cannot be changed. However, the workers had to go under the floor to carry out the work, which resulted in poor work efficiency and therefore insufficient pest control effects, and at the same time, there were disadvantages in that the health and hygiene of the workers were also not good.

An object of the present invention is to provide a foaming chemical dispersing device that is lighter in weight than conventional devices and has a structure that allows the spraying direction to be freely changed.

That is, in the device of the present invention, a porous member is attached to the opening surface at the tip of a cylindrical body with a part formed as an elastic bellows, a blower is attached to the base of the body, and a porous member is attached to the opening surface of the body. The present invention is characterized by a spray nozzle attached to the tip of a pipe whose base end is connected to a chemical tank so as to be located an appropriate distance inward from the sex member.

An example of the device of the present invention will be explained using the drawings.

As shown in FIG. 1, a cylindrical body (hereinafter referred to as a cylindrical body) 1
consists of a foamed part 1a and a bellows part 1b following it; the opening surface at the tip of the cylindrical body 1 is covered with a porous member, for example, a mesh 2, and an electric blower 4 having a fan 5 is provided at the base of the cylindrical body 1. .

On the other hand, to attach the spray nozzle 6 to the tip, connect the hose 7 whose base end is connected to a tank 9 containing a chemical solution 10 containing an active ingredient drug and a foaming agent along the bellows part 1b of the cylinder 1. The tip of the hose 7 is inserted into the foamed portion 1a of the cylinder 1 so that the spray nozzle 6 is located inside the net 2.

A pump 8 is provided in the middle of the hose 7, and by operating the pump 8, the chemical solution is supplied to the spray nozzle 6, where it is sprayed toward the net 2.

At the same time, when the blower 4 installed at the base of the cylindrical body 1 is activated, wind is generated by the rotation of the fan 5, and the chemical liquid sprayed from the nozzle 6 is forcibly sent forward by this wind,
It collides with the object, turns into foam, and scatters further forward.

The scattering distance of the foam is determined by the amount of air blown by the fan 5.

In the device of the present invention, since the diameters of the bellows portion 1b and the foamed portion 1a through which the forced air generated by the fan 5 passes are narrow, the amount of air blown can be made considerably smaller compared to the conventional device when the foam scattering distance is the same. This allows the blower 4 to be made smaller.

The blower used in the present invention is not particularly limited to the electric type shown in the drawings, but may also be an engine type or one with a compressor set.

The drug solution used in the present invention consists of a diluent that dilutes the active ingredient drug to a practical concentration, a foaming agent, and, if desired, other additives.

The foamed portion 1a and the bellows portion 1b may be formed integrally, or may be made into separate pieces and may be of an insertable type.

The bellows part 1b is made of hard polyvinyl chloride, polyurethane, AB
It is preferable to use plastic such as S resin.

In addition to the above-mentioned resins, the foamed portion 1a may be made of a light metal in the case of a plug-in type to ensure the diameter of the portion.

On the other hand, the hose 7 for supplying the chemical solution is made of a soft plastic such as nylon, soft polyvinyl chloride, or polyethylene.

The porous member may be any material that allows the chemical solution to foam, and may include a mesh, a perforated plate, a sponge, a nonwoven fabric, a metal scrubber, or a combination of these, with fine pores arranged in a regular or irregular manner. If it has, it can be selected and used as appropriate.

The size of the device varies depending on the place of use, but for example, the diameter of the foamed part 1a is 10cII11, followed by the bellows part 1.
The length of b is approximately 87n.

In addition, FIG. 1, 3 is a hanging ring for fixing the foamed part 1a,
11 is a valve for releasing air when the air generated by the blower 4 is too strong.

FIG. 2 shows an example in which the above-mentioned device is used for spraying a chemical solution.

Fig. 2 is a schematic diagram showing an example of spraying a chemical solution while foaming it in a narrow area under the floor using the device of the present invention. is passed through the hanging ring 3 provided in the foamed part 1a,
When inserted into the ventilation hole 13 under the floor, for example, the stainless steel rod 1
The folded portion 12a of No. 2 serves as a fulcrum, and the foamed portion 1a is fixed at a desired position.

Since the bellows part 1b and the liquid feeding hose T are made of resin, they can freely expand and contract according to the operation of the stainless steel rod 12.

Since the device of the present invention has a structure in which the blower 4 and the foaming part 1a are separated, the foaming part 1a can be made small and lightweight, and it is easy to operate and can be taken in and out through the narrow ventilation opening 13.

In addition, when inserting the cylinder 1 or pipe 7 through the ventilation opening, if there is a risk that it will rub against the surrounding walls and damage the cylinder, etc.,
It is also a good idea to cover the surrounding walls with a vinyl sheet or the like beforehand and then peel it off.

In the device of the present invention, as shown in FIG. 3 atb, the foaming part 1a is of a plug-in type, and the opening surface of the foaming part 1a is wider than the base, or conversely, the opening surface of the foaming part 1a is wider than the base. It may also have a narrow shape.

In the former case, the amount of air blown needs to be slightly increased, but the amount of foaming of the agent increases, which is advantageous when applying to a large area, while in the latter case, the amount of air blown can be reduced.
゛It is also suitable for spraying chemicals in narrow areas.

The shape of the foamed portion 1a is not limited to what is shown in the figure, but may be box-shaped or triangular.

Furthermore, when applying in a large space, it is possible for the operator to hold the foamed portion 1a without using a support and spread it to a desired location.

In this case, - the hanging ring 3 on the foaming section 1a may be omitted.As is clear from the above description, since the device of the present invention separates the foaming section and the blower, the weight of the foaming section can be reduced, and the drug The spraying operation is easy, and since the air passage connecting the blower and the foaming part is made of a bellows-type cylinder, it is expandable and retractable, making it easy for workers to enter even if the application area is a narrow place, such as under the floor. It is now possible to operate it from the outside.

Since the housing and ventilation passage are cylindrical, the capacity of the blower can be reduced without reducing the foaming and scattering ability of the drug, making the entire device smaller and lighter, as well as reducing energy consumption. It is something.
