Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a sprayer, and more particularly to a sprayer having an extremely simple structure and easy to operate.

[Conventional technology and its problems]

Conventionally, sprayers used for insecticides, cosmetics, etc. are made by simultaneously filling the main body of the sprayer with the liquid and gas to be sprayed, and spraying the liquid from the nozzle by the expansion pressure of the gas. You can Taking the case where the liquid is an insecticide as an example, an oil-based insecticide cannot be mixed well with a gas, so that the nebulizer loaded with the insecticide can be used in an upright state, that is, the nebulizer can be used horizontally. If it is turned on or vice versa, the pesticide cannot be sprayed from the nozzle, so that it is not practical. Incidentally, when the liquid is an aqueous insecticide, when using a sprayer, first, by shaking it to thoroughly mix the insecticide and the gas, regardless of the angle of use of the sprayer, the insecticide is smoothly added. Can be blown from the nozzle. But,
It is extremely inconvenient to be sure to shake before using, especially when the amount of the insecticide becomes small, the concentration of the sprayed insecticide may decrease significantly and should be improved. is there.

In addition, in the present nebulizer, since the liquid and the gas are contained in the same cylindrical main body, such a nebulizer cannot be used when the liquid does not come into contact with or mix with the gas. When the liquid and the gas are filled in the sprayer and used, if the liquid has high viscosity, the liquid may not be ejected smoothly.

In addition, in the present atomizer, the gas used is not necessarily a gas in the natural world, for example, when a gas of a compound of fluorine chlorine is adopted, the liquid can be sprayed with good volatility, but the environment It had a great impact on the environment, and there was a risk of environmental pollution.

On the other hand, in manufacturing the present sprayer, a means is used in which the liquid is first filled in the sprayer, and then high-pressure gas is filled in the sprayer to close the filling port. However, since it is necessary to continuously perform such a process of filling the gas and sealing the filling port, and further, it is necessary to prevent the gas from leaking before the filling port is sealed, an expensive facility is adopted. However, the cost of the atomizer could not be reduced because it is a heavy burden for the manufacturer.

The present invention has been made in view of the above facts, and has a very convenient manufacturing process, and a sprayer configured to be separately filled with a liquid and a gas, which can be used at any angle in use. Its purpose is to provide.

[Means for Solving the Problems]

In order to solve the above problems, according to the present invention, there is provided a sprayer having a cylindrical main body having a spray nozzle provided at an upper end and a bottom plate provided at a lower end, the spray device being provided in a mounting hole formed near a center of the bottom plate. And an upper half portion having an internal thread portion engraved on the inner peripheral surface is located inside the mounting hole, and a lower half portion having an external thread portion engraved on the outer peripheral surface is located outside the mounting hole, A cylindrical holder that cannot be detached from the bottom plate because the diameter of the ring-shaped protrusion formed on the outer peripheral surface of the upper half is larger than the diameter of the mounting hole, and is fitted onto the upper half of the holder. And an air bag having a wire mesh-like chamber wall, an air bag covered on the outer surface of the air chamber and held between the annular projection and the bottom plate at the periphery of the opening, and the inner circumference of the upper half of the holder.

And a high-pressure gas is filled from the air tap into the air bag, the high-pressure gas expands the air bag by operating the nozzle. It is characterized in that the liquid can be transferred to the nozzle via the porous liquid guiding tube and can be spattered from the nozzle.

[Action]

With the above configuration, when the nozzle is operated (for example, by pushing the nozzle) to spray the liquid,
The air bag can be naturally expanded by the high-pressure gas to transfer the liquid to the nozzle via the liquid guiding tube, and then be sprayed from the nozzle.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1 and 2, a sprayer according to the present invention comprises a cylindrical main body 1, a nozzle 10 provided above the top plate of the main body 1, a bottom plate 11 provided at the lower end of the main body 1, and the like. It has known members. The features of the atomizer are:
Provided in a mounting hole 12 opened near the center of the bottom plate 11,
The upper half part with the internal thread 22 engraved on the inner peripheral surface is the mounting hole
The lower half portion located inside 12 and having the external thread 23 engraved on the outer peripheral surface is located outside the mounting hole 12, and the diameter of the ring-shaped projection 21 formed on the outer peripheral surface of the upper half body is equal to the above mounting diameter. Hole 12
A cylindrical holder 2 that cannot be detached to the outside from the bottom plate 12 because the diameter is larger than that of The outer periphery of the air chamber 3 is covered with the peripheral edge 41 of the opening being the annular protrusion.
The air bag 4 held between the base plate 21 and the bottom plate 11, and the holder 2 described above.
Air tap 5 screwed into female thread 22 on the inner surface of the upper half
And the peripheral edge 41 of the opening of the air bag located between the ring-shaped projection 21 and the bottom plate 11 is firmly held by being screwed into the male screw portion 23 on the outer peripheral surface of the lower half of the holder 2. It is provided with a fixed ring 6 and a porous liquid guiding tube 7 connected to the nozzle 10 and arranged inside the tubular main body.

The air tap 5 is kept in a fixed screwed position by an abutting projection 51 provided around the lower end of the air tap 5. A washer 50 is provided between the contact protrusion 51 and the female screw portion 21.
Is intervening. This washer 50 has a function of preventing leakage of high-pressure gas.

Further, since the peripheral edge 41 of the opening of the air bag 4 is sandwiched between the ring-shaped protrusion 21 and the bottom plate 11, the function of a washer can be exerted. That is, after the high pressure gas is filled into the air chamber 3 from the air tap 50 to expand the air bag 4 outside the air chamber 3, the peripheral edge 41 of the opening can prevent the high pressure gas from leaking.

Before filling the high-pressure gas into the air bag 4, first, the liquid is filled into the cylindrical main body 1 from a filling hole near the nozzle 10. Since the mechanism such as the filling hole is publicly known, detailed description thereof will be omitted.

As shown in FIGS. 3 and 4, when the liquid in the tubular main body 1 is to be scattered, first, the nozzle 10 is pressed toward the tubular main body 1 so that the liquid guiding tube 7 is in communication with the outside world. Yes (Nozzle 10
Since the structure of is known, the description is omitted here). As a result, the air bag 4 is expanded by the high-pressure gas, and the liquid is compressed so as to be blown to the outside through the liquid guiding tube 7 and the nozzle 10. As a result, the liquid is smoothly sprayed from the nozzle 10 to the outside. By presetting the pressure of the high-pressure gas, the air bag 4 can be fully expanded into the tubular body 1 (see FIG. 4) so that the liquid disappears. There is no risk of remaining in the main body 1.

Since the length of the liquid guide pipe 7 reaches the vicinity of the bottom plate 11,
The liquid can be blown to the outside world until it runs out.

[Advantages of the Invention] As described above, according to the present invention, since the gas and the liquid are separated from each other, they do not affect each other, and the liquid and the gas are separately filled, which is extremely advantageous. is there.
Further, the manufacturing cost can be reduced due to its structural simplicity. In addition, when used, the liquid can be smoothly sprinkled even when the cylindrical main body is slanted or upside down, which is very convenient.
