Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spray gun for cleaning, and more particularly to a spray gun having an air gun having a jet nozzle dedicated to air.

[0002]

2. Description of the Related Art As a spray gun, a type equipped with a piston pump is used, but a cleaning liquid ejected by reciprocating pistons is intermittently ejected from the tip and applied to textiles and equipment. Used to remove dirt. FIG. 3 shows a conventional cleaning spray gun, which has a spray nozzle (b) at the tip of a piston pump (a) and a supply hose (d) by a piston (c) reciprocating the piston pump (a). )), And injects the cleaning liquid from the injection nozzle (b).

[0003] Here, the piston (c) is reciprocated by a motor (e), and the shaft (f) of the motor (e) is connected to a cam ring (g), and the cam ring (g) is connected to the cam ring (g). Is the eccentric shaft
(H) is provided. This eccentric shaft (h) is loosely fitted in the loose fitting groove (nu) of the slider (g), and if the cam ring (g) rotates, the slider (g) becomes the eccentric amount of the eccentric shaft (g). Reciprocate within the range. Above piston
(C) is connected to the slider (G), so the piston
(C) also reciprocates.

With the reciprocating movement of the piston (c), the cleaning liquid sucked up from the supply hose (d) is intermittently jetted from the jet nozzle (b) so that the dirt adhering to the cloth is washed away. However, depending on the properties of the fabric and the degree of dirt, the cleaning solution sprayed from the spray nozzle (b) may be inappropriate. For example, if a washing liquid is sprayed at high speed on a thin cloth such as silk, the cloth may be damaged or sometimes torn. Therefore, ultrasonic waves are sometimes used to remove dirt attached to the fabric. That is, the cleaning liquid is dropped on the cloth, and a horn is applied to vibrate the cloth to remove dirt by a synergistic effect of the cavitation and the cleaning liquid.

As described above, there are various types of cleaning spray guns. Basically, a cleaning liquid can be sprayed from a tip nozzle to remove dirt. However, the cleaning liquid containing the dirt only spreads to the surroundings, and even if dried as it is, stains remain on the cloth. Therefore, after the cleaning liquid has been sprayed to remove the dirt, the air must be sprayed to blow off the cleaning liquid adhering to the fabric, but for this purpose, a conventional cleaning spray gun is used. In some cases, an air gun that ejects air separately is used.

[0006]

As described above, the conventional cleaning spray gun has the above-mentioned problems.
The problem to be solved by the present invention is this problem,
Provided is a cleaning spray gun provided with an air gun and a spray gun without using an air gun separately.

[0007]

SUMMARY OF THE INVENTION A cleaning spray gun according to the present invention has a structure including a spray gun for spraying a cleaning liquid and an air gun for spraying air. The spray gun includes a piston pump, and the cleaning liquid is intermittently ejected from the tip nozzle by the piston pump.
Here, the configuration of the piston pump is not limited, and the piston pump may be reciprocated using a linear motor, or the piston may be slid by a cam mechanism rotated by the motor. That is, the reciprocating mechanism of the piston is not limited.

One of the air guns has a nozzle for jetting air, and can be used alternately with the spray gun. That is, dirt adhering to the cloth is washed away with the cleaning liquid sprayed from the spray gun, and the cleaning liquid remaining on the cloth is removed by the air sprayed from the air gun. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0009]

FIG. 1 shows an embodiment of a cleaning spray gun according to the present invention. In the figure, reference numeral 1 denotes a spray gun, and 2 denotes an air gun. The cleaning spray gun of the present invention has a structure in which the spray gun 1 and the air gun 2 are provided side by side, and can be selectively used as required. The spray gun 1 is mounted on the upper part of the handle 3, and one of the air guns 2 is adjacent to the spray gun 1 via the coupling 4. The handle 3 has a built-in motor, and can reciprocate the piston of the spray gun 1 to eject the cleaning liquid from the tip nozzle 5. Then, the air gun 2 jets air from the tip nozzle 6.

Here, the structure of the spray gun 1 is not particularly limited, and a cam, a link, or a linear motor can be used as a means for driving a piston pump for injecting a cleaning liquid from a nozzle. FIG. 2 shows a drive system using a cam, in which a piston pump 7 is composed of a cylinder 8 and a piston 9 reciprocating in the cylinder 8, and a supply hose 10 is connected to the cylinder 8 to supply a cleaning liquid. A supply port 11 is formed. The cleaning liquid that has entered the cylinder 8 from the supply port 11 is moved forward by the piston 9 so that
Erupts from However, a small amount of the cleaning liquid flows out as a drain without jetting. A drain hose 13 is connected below the casing 12, and the drain flows out from the outlet 14 to the drain hose 13.

By the way, a flange 15 is provided at the rear end of the piston 9.
The collar 15 is fitted into a screw hole of the slider 16 and screwed. Therefore, if the slider 16 slides along the guide groove or guide hole 17 of the casing 12, the piston 9 also slides. The sliding motion (reciprocating motion) of the slider 16 is performed by rotation of an eccentric shaft 19 formed on the cam ring 18.

The cam ring 18 is fixed to a shaft 21 of a motor 20 built in the handle 3, and if the shaft 21 rotates, the eccentric shaft 19 performs an eccentric movement to move the slider 1
No. 6 repeats reciprocation within a range of twice the eccentric distance a. When the slider 16 advances, the piston 9 also advances, and the cleaning liquid flowing from the supply hose 10 is jetted from the tip nozzle 5. Conversely, when the slider 16 moves backward, the piston 9 also moves backward to suck the cleaning liquid from the supply hose 10 and at the same time compress the air in the space 22 formed at the rear end of the casing 12.

That is, this spray gun has an air pump at the rear end of the casing 12, and the slider 16 functions as a piston of the air pump. The compressed air flows from a valve 24 provided at an outlet 23 through a hose 25 to a space 26 formed between the cylinder 8 and the slider 16, and forcibly drains the drain accumulated at the bottom of the space 26 to the drain hose 13. To be discharged. The drain hose 13 bends at the lower end of the outlet 14 and is guided upward. However, the drain flows through the drain hose 13 by being pushed by the compressed air sent from the air pump.

The casing of the motor 20 is a handle 3 of the spray gun. The handle 3 is provided with a switch (not shown), and the motor 20 is rotated by operating the switch. If the motor rotates, the piston pump 7 is driven, and the cleaning liquid is intermittently ejected from the tip nozzle 5. The dirt is washed away by applying the jet liquid to dirt adhering to the fabric.

The spray gun for cleaning according to the present invention includes an air gun 2 in addition to the spray gun 1 for spraying a cleaning liquid, and the air is jetted from a tip nozzle 6 of the air gun 2. By injecting the above-mentioned cleaning liquid to the dirty part of the fabric,
The dirt is washed off, but when the cloth is dried with the cleaning liquid remaining attached, the dirt may remain in the cleaning liquid, and the dried liquid appears as a stain. Therefore, the air sprayed from the air gun 2 is blown off over the attached cleaning liquid.

An air hose 27 is connected to the air gun 2 from an air compressor provided separately, and the air is jetted by pressing a switch provided on the handle 3. The spray gun 1 and the air gun 2 can be properly used. As described above, the cleaning spray gun of the present invention has a spray gun for spraying a cleaning liquid and an air gun for spraying air,
The following effects can be obtained.

[0017]

According to the cleaning spray gun of the present invention, the cleaning liquid can be sprayed from the spray gun to remove dirt adhering to the cloth. Then, the cleaning liquid adhering to the dough is blown off by the air sprayed from the air gun, and no stain remains on the dried dough. The spray gun and the air gun can be switched with a single switch, and can be used freely and easily.
