Description

Squirt gun

The invention discloses a spray-injecting dual-purpose gun, in particular to a housing for a spray-injecting dual-purpose gun having a recessed space for accommodating tools, and a nozzle for forming a large vacuum suction force for effectively sucking dust, And has an air outlet control to control the spray or suction spray gun.

According to the conventional cleaning machine such as a sewing machine, the oil or liquid in the mechanism is sucked into the collecting container by the flow of the gas in the passage; for example, the dust collecting gun device proposed by the Republic of China Patent No. M332098, the vacuuming device When the gun is used, the user presses the button portion 11 to open the gas valve 111 to make the gas from the intake line 2 through the first line 101 through the small port 121 and then enters the third line 132 to the second line in the barrel portion 13. 131 generates a suction force, so that the aforementioned oil and gas or liquid, waste, etc. can be sucked into the collecting gas. The vacuum gun of the prior art can only provide the action of vacuuming if the dust is dirty and accumulated in the barrel portion. In addition, the suction port must be manually wiped off. Moreover, the conventional dust suction gun has a large volume structure, the internal pipeline is too long, and only the pipe diameter changes to form a suction force, and the airflow is lost due to the passage of the pipe through too many corners. And the suction formed by the suction has the disadvantage of insufficient suction, and the absence of the above-mentioned vacuum cleaner is the direction that the inventors of the present invention are eager to study and improve. In view of the above needs, the inventors of the present invention have collected relevant materials, and have invented the dual-use guns through continuous trial and modification through various evaluations and considerations, and through years of experience in the industry.

The positioning structure 217 of the recessed space 216; in use, the pressing portion 244 can be pulled out to one side by a finger to disengage the cover 240 from the housing 21, thereby exposing the recessed space 216, and placing the object to be stored After entering the recessed space 216, the cover 240 is covered back.

The squirting gun combined with the above-mentioned structure forms a recessed space 216 on the casing 21, in addition to saving material, and the space inside the squirting gun is reused to make it concave. In addition to the functions of accommodating tools or spare parts, a recessed space 216 is formed in the casing 21, so that the injection molded casing 21 is less likely to be deformed, and the invention is excellent in innovation and practical convenience.

Please refer to the spray gun of the present invention shown in FIG. 7-9, wherein the air inlet 214 and the air outlet 215 of the casing 21 are respectively connected to the air outlet pipe 2151 by an air inlet pipe 2141, and the air inlet pipe 2151 is connected thereto. The control unit 22 has a pressing member 221, and a control member 222 is disposed at one end of the pressing member 221, and a valve body 224 is disposed at a tail end of the control member 222. The control member 222 is movably disposed in the air control duct 2142 and extends through the air inlet duct 2141. The pressing member 221 and the housing 21 have a returning member 223. The returning member 223 is a spring and the pressing member 221 is The nozzle 23 has a first through hole 231 and a second through hole 232. In this embodiment, the first through hole 231 communicates with the second through hole 232, and the first through hole 231 and the second through hole 232. The air inlet duct 2141 and the air outlet duct 2151 are respectively connected to each other, and the valve body 224 is respectively aligned with the first through hole 231 and the air inlet port 214, and the second through hole 232 is aligned. In the air outlet 215, an air outlet control member 26 is disposed on the air outlet pipe 2151 of the casing 21 adjacent to the air outlet 215. The air outlet control member 26 is a rotary control valve.

The spray-in dual-purpose gun combined by the above configuration, when the control mechanism 22 is pressed, the control member 222 placed in the gas control pipe 2142 is moved to make the gas control pipe 2142 and the valve body 224 at the end of the control member 222. A gap is generated, because the air inlet 214 communicates with the air outlet 215 and the spray pipe 212 via the valve body 224 and the nozzle 23, so that the gas flows from the air inlet port 214 through the gap between the gas pipe 2142 and the valve body 224 of the control member 222, and then passes through the nozzle 23. The second through hole 232 of the air outlet pipe 2151 ejects gas, and the spray pipe 212 adjacent to the nozzle 23 thus forms a vacuum suction force, and the dust on the member near the suction pipe 212 can be stored in the recovery container 25 (please refer to Figure 8).

In addition, as shown in FIG. 9 , an air outlet control member 26 may be disposed adjacent to the air outlet 215 mainly on the air outlet pipe 2151 of the casing 21 , and the air outlet control member 26 is a rotary control air valve 261 . A pressing ring 262 is disposed on the upper and lower sides of the rotary control valve 261, and a hollow screw 218 is disposed at the bottom end of the pressing ring 262. When the gas control member 26 is rotated to the closed position, the air outlet control member 26 is configured to block the flow of air from the nozzle 23 to the recovery container 25, so that the air flow is sprayed with high pressure gas by the spray pipe 212, and can be used to clear the outlet of the spray pipe 212. The dust on the member, the rotating hollow screw 218 is used to generate airtightness and adjust the rotation control valve 261 to be tight.
