Description

[Detailed description of the invention] This invention relates to an aerosol sprayer that sprays the required medicine, etc., and the injection tube attached to the injection port is placed in a narrow space with the nozzle for normal spraying. Each of the tubes has a bending tube made of a hard thin tube that can be inserted into the spray tube to spray, and the spray can be switched at any time.

In an aerosol sprayer, when the injection button protruding from the top of the container is pressed down against a spring, the injection is performed from the injection port provided in the front of the injection button, and the injection port has a nozzle that sprays a normal fixed range.
Alternatively, depending on the situation, a needle tube of a required length is selectively replaced on a part of the surface to be sprayed.

By attaching the injection pipe to the above-mentioned injection port, the injection pipe of this invention can be used to perform normal spraying and spraying to a specific area at any time without having to switch between them.

An embodiment of this invention will be described with reference to FIG. 1. Reference numeral 1 denotes an injection tube, which is used by inserting its base end into the injection port of an injection button 2 of a sprayer. This injection pipe 1 has a normal nozzle 3 at its tip, and an inclined hole 4 in the middle with a diameter slightly larger than the inner diameter of the injection pipe.
A short rod-shaped rotating rod 5 is irremovably fitted into the rotating rod 5, and a bending tube 6 of a required length is connected to the rotating rod 5.

Each of the rotating rods 5 has a through hole 7 located inside the injection tube 1 and extending along the axis of the injection tube, and a hook-shaped hole whose one end communicates with the bending tube 6 and whose other end opens perpendicularly to the through hole 7. 8, and in the state shown in FIG. 1, the through hole 7 opens into the injection tube 1 with both ends facing forward and backward, but one end of the hook-shaped hole 8 connected to the bending tube 6 is located inside the inclined hole 4. It is closed in contact with the circumferential surface.

This device has the above-described structure, and as described above, when the spray button 2 is pressed down in the state shown in FIG. 1, the spray liquid is sprayed from the nozzle 3 through the through hole 7.
In this case, the bending tube 6 hangs downward along the container of the sprayer, so that it does not interfere with the above-mentioned spraying operation.

Next, if you want to spray by partially inserting deeply into a part of the surface to be sprayed, hold the bending tube 6 and rotate the rotating rod 5 by 90 degrees to get the state shown in Fig. 2.
The through hole 7 is oriented horizontally, and both ends thereof are closed in contact with the inner circumferential surface of the inclined hole 4, and one end of the hook-shaped hole 8 is opened into the injection pipe 1. Therefore, the spray liquid enters the bending tube 6 from one end of the hook-shaped hole 8, and the required local spray can be performed.

This invention allows the spray to be switched simply by rotating the refraction tube 6 as described above, and the nozzle 3
In this case, the bending tube 6 faces downward, which is convenient for work, but the outer diameter of the rotating rod 5, that is, the inner diameter of the inclined hole 4, is made slightly larger than the inner diameter of the injection tube 1, so that the rotating rod 5 is inclined. Since the slotted surface of the hole 4 is inserted into the wall thickness of the injection tube 1, the opening to be closed by the inner peripheral surface of the inclined hole 4, that is, one end of the hook-shaped hole 8 in FIG. In FIG. 2, both ends of the through hole 7 are always closed outward from the inner circumferential surface of the injection pipe 1, so that airtightness can be increased. Hole 8
The inner diameter of can also be made larger accordingly.

As described above, this invention has a simple structure and is efficient, and is particularly suitable for use in spraying insecticides onto houses.
