Two-in-one spray gun

Abstract

The invention relates to a two-in-one spray gun. The two-in-one spray gun comprises a gun body, a trigger and a conveying pipe connected to the rear portion of the gun body, wherein the front portionof the gun body is detachably connected with a nozzle mechanism. In order to facilitate replacement of the nozzle mechanism, a lock catch mechanism for locking the nozzle mechanism and the gun body isarranged between the nozzle mechanism and the gun body. The nozzle mechanism comprises a cylindrical and hollow shell. A connecting cover is arranged at the end, close to the gun body, of the shell.A conical funnel-shaped nozzle is arranged at the end, away from the gun body, of the shell. Compared with the prior art, the two-in-one spray gun has the advantages that raw materials and the gun body are separated, the structural size of the two-in-one spray gun is reduced, and operation is more flexible; an unlocking device at the trigger prevents misoperation; a nozzle consumable part is rapidly replaced through one key, and the efficiency is improved during continuous operation; and the whole components are simple and easy to machine, assemble, disassemble and clean.

Description

technical field [0001] The invention belongs to the technical field of spraying equipment, and in particular relates to a two-in-one spray gun, which is suitable for two-component raw materials, foaming agent mixing, two-component beautification and the like. Background technique [0002] Coatings and adhesives are widely used in industrial manufacturing and building decoration as production auxiliary materials. The existing construction methods are generally two-pipe manual propulsion and double-pipe pneumatic propulsion, both of which are to install the two-component raw materials on the gun body separately. The two-component raw material is extruded by pushing the slide bar on the gun body forward, so that the raw material flows out to the construction surface after being mixed through the nozzle and the internal spiral blade to complete the work. This operation method has certain disadvantages: [0003] 1. Since the raw material is installed in the gun body, the volume o...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the raw material is installed in the gun body, the volume of the gun body increases and the weight is heavy, which limits the flexibility during operation;

[0004] 2. Frequent replacement of raw materials is required during continuous operation;

[0005] 3. There will be overflow after stopping the gun during the operation;

[0006] 4. Manual labor is intensive, time-consuming and labor-intensive
