Description

Technical Field

[0001] The utility model relates to the technical field of sanitary wares, and particularly relates to a dual-outlet spray gun. Background Art

[0002] Spray guns are very common in sanitary wares. At present, according to the material and production process, spray guns can be divided into sand casting, stamping, pressure casting and injection molding. Among them, 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 and are also closely related to their structures.

[0003] Most of the current dual-outlet spray guns use a T-shaped structure. Therefore, there is enough space at the head to accommodate two water valves to control the water outlet of two channels respectively. With the development of the market, the visual experience brought by the traditional T-shaped dual-outlet spray gun has become fatiguing. Therefore, changing its shape to a strip structure is more conducive to the shape design. However, due to the influence of the overall cross-sectional size of the strip-shaped dual-outlet spray gun, it is often difficult to normally install the traditional integrated water valve finished product into it. Therefore, to install the valve core on the basis of not changing the strip-shaped appearance, it is difficult in terms of design and later assembly due to the limitation of the cross-sectional space size, and factors such as the influence of the overall appearance, how to process the internal structure and waterway, and how to simply and conveniently install the valve core into the spray gun need to be considered.
