Pneumatic cleaning gun

The present invention relates to a cleaning gun, and more particularly to a pneumatic cleaning gun.

With the improvement of the quality of life in clothing, food, shelter and entertainment, families generally have vehicles such as cars or recreational vehicles. When the vehicle is running on the road, it will inevitably be contaminated with dirt, dirt and other dirt. Therefore, after the vehicle has been running for a period of time, it must be cleaned and brushed to keep the vehicle clean. Therefore, many car owners will use the holiday to send the car to the car wash for cleaning. When cleaning the car body, the manufacturer first scrubs the car body with a foam-attached detergent, and then rinses the detergent foam with a water column through a water pipe. However, in the cleaning process, the water column of the water pipe is often insufficient, so that the dirt on the car body is not easily cleaned and the dirt and sand are still left.

Therefore, some manufacturers have developed a rotary air spray gun. The swirling air spray gun uses high-pressure air to pump the liquid in the liquid cylinder out of the liquid take-up tube, so that the liquid is mixed with the high-pressure air and then sprayed out from the nozzle, thereby improving the washing ability of the vehicle body.

In addition, more people have developed a swirling air spray gun with vacuuming capability. The swirling air spray gun with vacuuming capability has a suction port for vacuuming in addition to the air inlet for the jet and the liquid inlet for the spray. However, since the inlet port, the inlet port, and the suction port require an external pipe to be connected to the air supply or supply device, an increase in the number of assembly ports may result in inconvenient assembly of the external pipe. Therefore, how to improve the assembly convenience between the rotary air spray gun and the external pipeline will be one of the problems that the researcher should solve.

The present invention provides a pneumatic cleaning gun for improving the assembly convenience between the rotary air spray gun and the external piping.

The pneumatic cleaning gun disclosed in one embodiment of the present invention comprises a gun body, a nozzle cover body and a transfer tube body. The gun body includes a body portion, a grip portion and a fluid nozzle portion. The grip portion and the fluid nozzle portion are respectively connected to opposite sides of the gun body portion. The nozzle cover is mounted on the body of the gun body. The nozzle cover surrounds a cover space, and the fluid nozzle portion is located in the cover space of the nozzle cover. The transfer tube body is connected to the nozzle cover. The transfer tube body has a suction port. The suction port is connected to the covering space. The transfer tube body is rotatable relative to the gun body and has at least a first use position and a second use position.

According to the pneumatic cleaning gun of the above embodiment, the adapter tube body can be turned to the user's customary position to assemble the external pipeline through the relatively rotatable adapter tube body, thereby improving the space between the swirling air spray gun and the external pipeline. Assembly convenience.

The above description of the present invention and the following description of the embodiments are intended to illustrate and explain the principles of the present invention and to provide a further explanation of the scope of the present application.
