Embodiment Construction

[0016] The structure of the present invention will be explained and described in detail below in conjunction with the accompanying drawings.

[0017] Such as Figure 1-2 As shown, the liquid spray gun of the present invention includes a spray head housing 1, a spray cap 2, a nozzle 3, a liquid passage 4, and a gas passage 5. The nozzle 2 is detachably mounted on the front end side of the spray head housing 1, and the outside of the nozzle 2 is connected to the spray nozzle by a thread 101. The cap 2 and the front end of the spray cap 2 are provided with an opening 20 communicating with the nozzle 3, and the nozzle 3 communicates with the liquid channel 4 and the gas channel 5 respectively.

[0018] The spray cap 2 of the liquid spray gun of the present invention can be adjusted to connect the nozzle 3 through the screw thread 101, and the spray cap 2 is screwed in and out, so that the distance between the front opening of the spray cap 2 and the nozzle 3 nozzle can be adjusted...

Abstract

The invention discloses a liquid spray gun. The liquid spray gun comprises a spray head shell, a spray cap, a nozzle, a liquid channel and a gas channel; one side of the front end of the spray head shell is detachably provided with the nozzle; the outer side of the nozzle is connected with the spray cap through a screw thread; an opening communicating with a nozzle orifice of the nozzle is formed in the front end of the spray cap; and the nozzle respectively communicates with the liquid channel and the gas channel. According to the liquid spray gun disclosed by the invention, the distance between the opening in the front end of the spray cap and the nozzle orifice of the nozzle is regulated through the screw thread, so that the pressure of a liquid sprayed by the nozzle and the volume of the sprayed liquid are changed, and the sprayed liquid is good in atomized quality and uniform in spray, and no liquid drops flow out; both the spray cap and the nozzle can be dismounted, so that the spray cap and the nozzle are conveniently replaced, and the inside liquid channel is conveniently cleaned; a liquid cup is replaceably connected so that the liquid spray gun disclosed by the invention can be suitable for spraying for different purposes; and an air pump shell is detachably connected with the spray head shell, so that the liquid spray gun is conveniently carried, and the inside channels are conveniently cleaned.

Description

technical field [0001] The invention relates to a spray gun, in particular to a liquid spray gun which is convenient for assembly and disassembly. Background technique [0002] A spray gun is a device that uses liquid or compressed air to release quickly as power, and is usually used for spraying and cleaning. Usually, the spray gun includes a casing, an air passage, and a liquid nozzle assembly, and the liquid nozzle assembly is fixedly installed at the front end of the casing and cannot be disassembled. However, in long-term spraying applications, the liquid medium will accumulate in the liquid passage of the spray gun and other structures, which will adversely affect the spraying effect and may contaminate subsequent applications. In addition, the air pump assembly, the liquid pipe assembly and the casing are integrated, which has the disadvantages of being inconvenient to carry and difficult to clean the internal passages. Contents of the invention [0003] In order ...
