DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas-pressure spray device for paints, pesticides, pesticides or detergents.

[0002]

2. Description of the Related Art FIG. 5 shows paints, pesticides,
A spray can 1 for insecticide or detergent, 2 is a spout, and 3 is a protective cap provided around it.
Here, the height of the protective cap 3 is set slightly higher than that of the spout 2, so that the spout does not touch the other objects alone and inadvertently actuates. The protective cap 3 is engaged with a ring-shaped projection 4 formed around the nozzle body 2 to press the nozzle body 2 from its upper opening.

[0003]

Various spray cans using the above-mentioned high-pressure gas can be used for paints, pesticides and pesticides by the action of gas pressure sealed in the can through a nozzle hole only by pressing the spout with a finger. Alternatively, they can be easily and frequently used because they can quickly spray a detergent or the like. By the way, in the above, when the gas pressure in the can is high for the initial use and after a certain period of use, the gas pressure in the can is changed, the jetting action is weakened, and this causes a cause of uneven coating. ing. The present invention has been made to solve the above problems.

[0004]

SUMMARY OF THE INVENTION According to the present invention, one end of an elbow pipe is attached to a spout of a conventional gas-pressure spray can with a certain clearance from the spout. An opening is formed on the spray discharge side of the canister, and a trumpet-shaped opening and expanding inclined wall is formed at the opening, and a discharge hole corresponding to the nozzle hole of the nozzle is formed in the center. In addition, the trumpet-shaped inclined wall is fitted with a piece that surrounds the discharge hole and has several air blowing holes,
The elbow pipe is provided with an operation lever capable of pressing the upper part of the in-tube spout, and the other end of the elbow pipe having the above configuration is connected to the outlet of the power blower. At this time, an air hole formed in the inclined wall surface of the bridge body is formed so as to have an inclination angle of 1 ° to 15 ° with respect to the jetting direction of the jet liquid from the center hole.

FIG. 1 shows an auxiliary body 5 used in the present invention.
FIG. 2 is a longitudinal sectional view of FIG. The auxiliary body 5 is formed of an elbow tube made of a synthetic resin or the like, and the inner diameter of the tube is engaged with the ring-shaped projection 4 of the spray can 1. Thus, an opening 6 is formed at a predetermined height position of the vertical portion 5a of the auxiliary body 5, and a frame 7 described below is attached.

Here, the bridge body 7 is a trumpet-shaped inclined opening wall 7.
a, and a discharge hole 7b of a spout body is formed inside the center. Thus, a plurality (eight in the illustrated example) of air blowing holes 7c are formed in the trumpet-shaped inclined opening wall 7a so as to surround the central discharge hole 7b.
Here, the air outlet 7c is usually formed so as to be in the same direction parallel to the center line of the central discharge hole 7b. = 1 to 15 °.

Reference numeral 8 denotes an operation lever provided at a slightly upper position where the frame 7 is located. The pressing lever 8a is attached to the shaft 8b into the vertical portion 5a of the elbow tube 5, and both ends of the shaft 8b are outside the tube. To connect to the levers 8c, 8c.
Here, the pressing rod 8a is mounted eccentrically with respect to the shaft 8b, and when the lever 8c is turned downward, the rod end p of the pressing rod 8a is attached to the spray can 1 of an elbow pipe described later.
It comes into contact with the head of the spout and pushes it down.

FIG. 3 shows the auxiliary body 5 having the above-described structure and the spray can 1.
FIG. 4 is a view showing a state of use, in which the protective cap 3 of the spray can 1 is removed, and the vertical portion 5a is brought into contact with the ring-shaped projection 4 from above. The engagement is stopped so that the inner diameter of the portion 5a matches. Thus, the piece 7 of the vertical portion 5a is positioned at the front side of the spout 2 of the spray can 1. Specifically, the spout 2 is operated by operating the lever 8c. When p pushes down the upper part of the nozzle body 2 a little, and the jetting liquid 9 is ejected from the nozzle hole m, the nozzle hole m is made to correspond to the discharge hole 7b of the piece 7.

Reference numeral 10 denotes an outlet of a blower (not shown) provided at the end of the horizontal portion 5b on the other side of the elbow pipe 5, and when the spray can 1 is used, the wind of the blower blows the vertical portion 5a.
It is made to be ejected from the discharge hole 7b and the air blowout hole 7c of the piece 7 of FIG. That is, in the apparatus of the present invention having the above structure, when the liquid is sprayed from the spray can 1, the lever 8 c is swung so that the pressing rod 8 a presses the head of the spout 2 at the end thereof. The liquid is ejected from the nozzle hole m, and this is ejected forward from the ejection hole 7b of the frame body 7. In this case, the outer periphery of the ejected liquid 9 is surrounded by the wind sent from the blower. So that it can be blown forward. A dryer or the like is used as the blower.

Specifically, the air from the blower which flows out from the discharge hole 7b and the air outlet 7c of the piece 7 forms a cylindrical curtain 11 surrounding the jet liquid 9 from the outer periphery.
The surroundings are not unexpectedly diffused by the influence of the outside air, and the jetting liquid 9 is accelerated to increase the jetting efficiency. That is, this becomes more remarkable as the gas pressure in the spray can 1 decreases. In particular, when spraying a coating liquid, etc., it will be possible to effectively discharge the spray in the can in the end, and the paint will not spread to the surroundings during spraying and create an environment .

In the above embodiment, the air outlet 7c is set at 1 ° to 15 °.
The inclination angle θ of ° means that the cylindrical curtain 11 positively forms a swirling flow accompanying the rotation of the earth. Specifically, the energy due to the swirling flow is outside the jet liquid. The mist can travel while effectively involving the expanding mist and applying thrust. At this time, the swirl flow can be formed as either a right swirl flow or a left swirl flow.However, a swirl flow that is formed as a left swirl flow when viewed from the outlet side of the jet is used at north latitudes due to the rotation of the earth. More effectiveness is obtained from the experimental results of the present invention.

[0012]

The present invention is constructed as described above, and the specially constructed protective body is attached to the spout of a disposable spray can using gas pressure, so that from the first use. A uniform injection effect can be obtained regardless of the change in the gas pressure in the can. In the present invention, the outer air curtain prevents the spray mist from being affected by the cross wind, etc., and also suppresses a decrease in the injection efficiency from the beginning to the end by accelerating the speed of the spray mist. It will be. When wind blows in insecticide spraying or painting work, etc. (even when there is no wind, a cross wind is generated by the hand movement operation), in this state, the scattering of spray mist causes environmental pollution, but the present invention Does not cause such a problem. In addition, the particle velocity and adhesion distribution of the spray liquid are made uniform, which contributes not only to improvement in workability but also to improvement in economy.
