Embodiment

[0034] Example: such as figure 1 , figure 2 and image 3 As shown, the foam spray gun in this embodiment includes a gun body 1, a spray head 2, a wrench 3, a one-way liquid inlet mechanism 4, a piston rod 8, a piston 9, a reset member 91, a one-way valve 6, a first screen 51, The second screen 52 and the liner 7 .

[0035] The gun body 1 has a foam generating channel, and the foam generating channel includes a horizontal channel 11 and a vertical channel 12 . The nozzle 2 is arranged on the head of the gun body 1 and is connected to the injection port of the horizontal passage 11, and the wrench 3 is arranged on the gun body 1 in a rotatable manner.

[0036] The one-way liquid inlet mechanism 4 includes a pump body 42, balls 41 and a large cover 43. The pump body 42 is located at the liquid inlet port of the gun body 1, and the upper end has a V-shaped liquid outlet, and the lower end is connected with a water inlet pipe 44. Spheroid 41 is positioned on the V-shaped liqui...

Abstract

The invention provides a foam spray gun. The foam spray gun comprises a gun body, a spray head, a trigger, a one-way liquid feeding mechanism, a piston rod, a piston, a resetting piece, a check valve, and a screen, wherein the gun body is provided with a foam generation channel; the piston rod is arranged on the inner side of the trigger, can move inwards under the drive of the trigger, and is assembled with the gun body in a matched way; the piston is arranged in the inner chamber of the piston rod, can move together with the piston rod, and is matched with the gun body to form a first chamber and a second chamber; and the check valve and the screen are arranged in the foam generation channel of the gun body. Compared with the conventional technology, the foam spray gun has the advantages that: a foam generation mechanism which consists of the check valve and a check valve sheet, is organically combined with the first chamber and the second chamber, so air and liquid are converged at a liquid outlet of the check valve to generate foam and then enter the screen for the secondary foaming; and foam generation is rich and due to a trigger type design, handfeel of repetitive operation is good.

Description

technical field [0001] The invention relates to a liquid spray gun, in particular to a spray gun capable of generating foam, which can be applied to car washing, glass washing and other occasions. Background technique [0002] At present, the spraying device used for detergent, cleaning liquid and cosmetics is mainly spraying, but when it is used as a local spraying, the traditional spraying method is used, and the amount of spraying is not well controlled, which often leads to waste of spraying liquid. phenomenon, and the use of foam injection will be more reasonable. In addition, foam injection provides users with a new injection method and provides a new market for the injection device market. [0003] Existing foam injection is installed on the spray gun by a foam nozzle basically to realize the foam injection function, as the Chinese invention patent of ZL95117596.3 "foaming nozzle assembly for trigger injector" (authorized announcement number: CN2632010C), comprising ...
