[0004] In order to realize the above-mentioned purpose, the following technical scheme is adopted:

[0005] A structure of wireless electric spray gun, including the gun body, the gun body includes the gun tube and the handle, the handle is provided with the control wrench, the bottom of the handle is provided with the lithium battery general joint, the micro booster pump is arranged in the gun tube, the micro booster pump has the water inlet joint and the water outlet joint, the control wrench controls the on-off of the micro booster pump and the lithium battery circuit, characterized by: the water inlet joint is communicated with the water inlet pipe of the micro booster pump through the connecting channel, one end of the connecting channel is communicated with the water inlet pipe, the water inlet control valve is arranged in the connecting channel, the water inlet control valve includes the piston rod, the sealing seat and the reset spring, the piston rod is provided with the sealing block head matched with the shape of the port of the connecting channel at the end corresponding to the water inlet pipe, the two ends of the reset spring are abutted on the sealing block head and the sealing seat respectively, the free end of the piston rod passes through the piston hole of the sealing seat, and the free end of the piston rod is connected with the control wrench of the gun body through the pull rod.

[0006] The connecting channel is provided with the pin hole vertical to the axis of the connecting channel at the position corresponding to the sealing seat, the sealing seat is provided with the clamping groove at the position corresponding to the pin hole, and the clamping pin is inserted into the pin hole to fix the sealing seat to the port of the connecting channel.

[0007] Two pin holes are formed in the connecting channel, and the clamping pin is a U-shaped clamping pin.

[0008] The water inlet control valve controls the on-off of the water inlet, thereby solving the liquid leakage problem of the existing electric spray gun connected with the tap, and has the characteristics of reasonable structure and convenient operation. BRIEF DESCRIPTION OF DRAWINGS
