Rechargeable handheld electric spray gun

Abstract

The invention belongs to the technical field of spray guns and particularly relates to a rechargeable handheld electric spray gun. A gun body and a base are integrated; the front end of the gun body is provided with a gas nozzle; a plug is disposed in a plug mounting cavity inside the gun body; the front end of the plug mounting cavity is provided with a paint nozzle; the upper portion of a housing is provided with a gas chamber; the lower portion of the housing is provided with a handle; the gas chamber is in communicated connection with the gun body; a motor is disposed in the gas chamber; fan blades are disposed on a motor shaft of the motor; the motor and the plug are driven to act by a trigger; a liquid pipeline is arranged on the base and respectively communicated with a suction pipe and the plug mounting cavity; the base is provided with an intake pipeline communicated with the gun body; a one-way valve is disposed on the intake pipeline; the housing is provided with a power source for powering the motor. The rechargeable handheld electric spray gun has the advantages that a silencer and a grille are not required, noise is low, the one-way valve has the function of reflow preventing, and the material in a paint tank is prevented from overflowing due to pressure after spraying stops; a rechargeable battery is used as the power source, so that the rechargeable handheld electric spray gun is suitable for uses anywhere and convenient to use.

Description

Technical field [0001] The invention belongs to the technical field of spray guns, and particularly refers to a rechargeable hand-held electric spray gun. Background technique [0002] At present, the spray gun is a spraying equipment that atomizes the paint, and then sprays the surface of the painted workpiece to obtain a beautiful and uniform coating layer. The atomization effect of the spray gun has a very important effect on the surface of the sprayed workpiece. [0003] Patent No.: 200510076514.6 discloses a spray gun, and its structure is: the spray gun can be driven by a rod mounted on a sleeve in a pivoting configuration, the sleeve contains the atomizing nozzle, and the airflow can be generated by an air turbine corresponding to the spray gun, The air turbine and its motor are coaxially or almost coaxially arranged on the spray gun atomizing nozzle on the side of the handle opposite to the sleeve carrying the atomizing nozzle, so that the air flow from the air turbine is ...

AI Technical Summary

Problems solved by technology

The motor adopts a new type of motor structure, and the stator and rotor assembly (stator and rotor) are arranged on the air inlet side of the fan blade, that is, the stator and rotor assembly is arranged at the air inlet, and the stator and rotor assembly are forced to cool with cold air to improve the heat dissipation effect , this kind of heat dissipation structure is more complicated, and the noise is larger

At the same time, neither of the above two patents is equipped with a one-way valve. After the spraying is stopped, the material in the watering can will flow back, which seriously affects the quality of the product.

The power supply of traditional spray guns is powered by plugs inserted into sockets, so the scope of use has great limitations, especially in some cases where the scope of use is relatively large, it is necessary to realize electrical connection through an adapter socket, which is not easy to use. convenient
