Description

Technical Field

[0001] This utility model relates to the field of bathroom products, specifically to a spray gun. Background Technology

[0002] Spray guns are very common in bathroom products. Currently, spray guns can be divided into sand casting, stamping, pressure casting, and injection molding according to their materials and manufacturing processes. Sand casting and stamping are suitable for brass materials, pressure casting is suitable for zinc alloy materials, and injection molding is suitable for plastic materials. Different materials determine different processes, which are also closely related to their structure.

[0003] Currently, spray guns with strip-shaped shapes produced by injection molding, especially the dual-outlet type, have two valve chambers. Due to the influence of the water channel layout, it is difficult to achieve one-piece demolding (i.e., for single-outlet type spray guns, the inlet channel can be demolded from the inlet side, and the outlet channel can be demolded from the outlet side). For dual-outlet type spray guns, since the two valve chambers are arranged one in front of the other along their overall length, the mold core must be able to smoothly communicate with the two valve chambers when the inlet channel is demolded from the inlet side, and the mold core used to construct the two outlet channels and communicate with the two valve chambers must also be able to be demolded from the outlet side. This places extremely high demands on the overall structure and water channel layout.

[0004] To address the aforementioned issues, Chinese patent CN202320262362.2 discloses a spray gun bracket, comprising a bracket body with first and second water control sections. Each of the first and second water control sections includes a sliding hole and a valve chamber, with the sliding hole connecting to the valve chamber. A valve seat is provided within the valve chamber, dividing it into an inlet chamber facing the sliding hole and an outlet chamber facing away from it. A plug mounting position is provided on the side of the outlet chamber away from the valve seat. A water inlet channel is provided on the rear end face of the bracket body. A branch channel is provided within the bracket body, with one end connected to the inlet channel and the other end extending towards the front end of the bracket body, passing through the inlet chamber of the first water control section, and reaching the inlet chamber of the second water control section. A central water outlet channel and peripheral water outlet channels surrounding the central water outlet channel are provided on the front end face of the bracket body. The central water outlet channel communicates with the outlet chamber of the second water control section, and the peripheral water outlet channels communicate with the outlet chamber of the first water control section.

[0005] Although the aforementioned patents have solved the dual-outlet and production problems, their outlet directions are all forward. Therefore, during use, only the outlet type can be changed, but the outlet direction cannot be adjusted. Utility Model Content
