Description

Improved generation spray gun seat and spray gun subassembly

Technical Field

The utility model relates to a bathroom technical field, concretely relates to improved generation spray gun seat and spray gun subassembly.

Background

In the interior decoration process, people often install a toilet spray gun near a toilet for cleaning the toilet or cleaning a mop and the like for convenience. The wall body is provided with an angle valve with one dividing into two parts, some angle valves are also provided with clamping grooves for inserting spray guns, the closestool is connected with one water outlet of the angle valve, and the spray gun is connected with the other water outlet, as shown in CN216382670U which is a multifunctional tee. When the spray gun seat or the angle valve is connected to a wall body, the water inlet connector and the water supply connector in the wall body are exposed outside, so that the water supply connector is exposed, and the appearance is not attractive enough; and the spray gun seat and the angle valve need to be integrally rotated to be connected with the water supply joint through threads during installation, so that the installation is troublesome.
