Description

[Detailed description of the invention] (Purpose of the invention) This invention provides a compact and portable spraying means that is convenient for spraying environmental chemicals such as deodorants and air fresheners indoors and especially in passenger cars. It is in.

(Structure of the invention) This invention will be explained below with reference to an embodiment shown in the drawings. 1 is a pressure-resistant container such as a Lumi can,
A chemical solution is housed inside along with a liquefied gas propellant. An elastic gasket 2 is fitted into the mouth 11 of the closed container 1, and the elastic gasket 2 has a thick-walled cylindrical shape and has an axial hole 21 in which liquid can accumulate. That is, in the illustrated example, the upper end of the liquid suction pipe 5 is fitted into the lower end of the shaft hole 21 in order to supply liquid from the bottom of the pressure container 1 to the shaft hole 21. The liquid suction pipe 5 is not necessary.
3 is a hollow valve stem with a bottom, and its base 31 is fitted into the shaft hole of the elastic gasket 2. An annular groove 32 is bored in the circumferential surface of the base 31, and this annular groove 32 is connected to an axial hole 33 of the valve pedicle. In this way, the shaft hole surface of the elastic gasket 2 and the annular groove 32 constitute an injection valve. A weight body 4 is fitted to the tip of the valve stem 3. An injection port 42 is provided at the top end of the weight body 4, and the injection port 42 is connected to the shaft hole 33 of the valve stem through a guide hole 41 in the body 4 bored in the weight body 4. In this way, the pressure vessel 1 is moved forward and backward.
If you swing it in any direction, such as left or right or diagonally, the above-mentioned injection valve will open and the chemical will be sprayed.

This device is constructed as described above, and the base 31 of the valve stem 3 with the weight body 4 fitted at the tip is fitted into the shaft hole 21 of the thick-walled cylindrical elastic gasket 2, and the elastic gasket 2 has a pressure-resistant structure. Since it is fitted into the mouth 11 of the container 1, if you hold the pressure container 1 in your hand and shake it lightly, the weight body 4 will swing around the base 31 of the valve stem, and the pressure container 1 will move. The engagement position of the base portion 31 of the valve stem with respect to the shaft hole surface of the elastic gasket 2 changes slightly depending on the inclination of the valve stem 3 relative to the valve stem 3. This change in the engagement position creates a gap between the shaft hole surface and the circumferential surface of the base 31, and this gap forms the annular groove 3.
2, thus opening the above-mentioned injection valve. Since the axial hole 21 at the lower position of the valve stem 3 is filled with the chemical liquid under pressure, the medicinal liquid enters the annular groove 32 and the axial hole 33 of the valve stem connected to the annular groove 32 and the guide hole. 41 and is injected from the injection port 42. When holding the pressure container 1 in your hand and shaking it in any direction, the above-mentioned narrow area around the base 31 of the valve stem
Although the location of occurrence of the annular groove 32 is also uncertain, the annular groove 32
Since it extends around the entire circumference, no matter what direction you swing it, it will be sprayed from the injection port 42. Since the injection port 42 is provided at the top end of the weight body 4 fitted to the tip of the valve stem 3, the direction of injection is always approximately in the axial direction of the pressure vessel 1. Therefore, there is no need to determine the injection direction each time during use.
In addition, as a measure to prevent erroneous injection during transportation and other operations, it is preferable to attach a protective cap 6 as shown by the imaginary line.

(Effect of the invention) Thus, according to this invention, the purpose of distributing chemical solutions such as deodorants and air fresheners can be achieved by simply holding the container in one hand and shaking it freely without considering the direction of shaking. It can be used not only when spraying inside a room or an assembly room, but also because there is no need to consider the direction of spraying, and there is no need to rely on visual inspection to determine the direction of the spray, so it is especially suitable for use by drivers in passenger car cabins. It is convenient for applications such as making the environment inside a vehicle more comfortable.

[Brief explanation of drawings]

The drawing is a longitudinal sectional view of one embodiment of this device. 1 is a pressure container, 11 is a mouth part, 2 is an elastic gasket, 3 is a valve stem, 31 is a base part, 32 is an annular groove, 33 is a shaft hole, 4 is a weight body, 41 is a guide hole, 42 is an injection port, 5

Claims (1)

[Scope of utility model registration request] A thick-walled cylindrical elastic gasket 2 having a shaft hole 21 in which the liquid can accumulate is fitted into the mouth part 11 of the pressure container 1 which contains a chemical solution together with a liquefied gas propellant, and a ring is made on the circumferential surface of the base part 31. The base 31 of the bottomed hollow valve stem 3 with the groove 32 connected to the shaft hole 33 is inserted into the shaft hole 21 of the elastic gasket, and the shaft hole surface of the elastic gasket 2 and the ring groove 32 constitute an on-off valve, and the injection port is closed. 42 at the top end is fitted onto the tip of the valve stem 3, and the injection port 42 is connected to the shaft hole 33 of the valve stem through the guide hole 41 bored in the weight body 4. A device for dispensing deodorant, etc., which opens a valve and sprays the chemical solution by swinging it in any direction such as front and back, left and right, and diagonally.
