Description

Technical fields:

[0001] This utility model belongs to the field of hardware manufacturing technology, specifically relating to a plastic shower switching valve. Background Technology

[0002] Shower rods are a common component of modern shower systems, typically integrating an overhead shower and a hand shower. The switching valve is the core component of the shower rod, used to switch the water flow between the overhead shower and the hand shower.

[0003] Traditional shower rod switching valves are mostly made of metals such as brass, which have the advantages of high structural strength and durability. However, they also have obvious disadvantages: First, metal materials are expensive and dense, resulting in a heavy overall product and inconvenient installation; second, the metal valve body needs to undergo surface treatments such as chrome plating for rust prevention and aesthetics, which is a complex and environmentally unfriendly manufacturing process; finally, after long-term use, the surface plating may wear or peel off, affecting the appearance and making it prone to rust. Utility model content:

[0004] The technical problem to be solved by this utility model is to provide a plastic shower switching valve, which has a simple structure, lower cost, lighter weight, corrosion resistance and more environmentally friendly production.

[0005] The technical solution of this utility model is to provide a plastic shower switching valve, including...

[0006] The valve body assembly consists of a plastic housing and a plastic water distribution core disposed within the housing;

[0007] The valve core, located inside the water distribution core, is used to control the opening and closing of the water circuit and its switching.

[0008] The control assembly includes a handle connected to the valve core to drive its rotation;

[0009] The water inlet channel includes a first connector disposed on the water distribution core for connecting the water inlet pipe;

[0010] The water outlet channel includes a water outlet connector disposed on the water distribution core for connecting the top spray water outlet pipe, and a second connector for connecting the handheld shower head water outlet pipe.

[0011] In use, the valve core actuates under the drive of the handle to switch the water flow from the inlet channel to the outlet channel via the outlet connector or the second connector.

[0012] Preferably, a wear-resistant ring is provided between the handle and the housing.

[0013] Preferably, the mounting assembly includes a mounting plate and an expansion tube for fixing the switching valve to the wall.

[0014] Preferably, a pressure cap is also included, wherein the valve core is fixedly encapsulated within the water distribution core by the pressure cap.

[0015] Preferably, O-rings are provided at the connection points of the water outlet connector, the first connector, and the water distribution core for sealing.

[0016] Preferably, the valve core is provided with a valve stem, and the handle is fixedly connected to the valve stem by an insert and a screw.

[0017] Preferably, the outer shell and the water distribution core are integrally molded from engineering plastics using an injection molding process.

[0018] Preferably, the mounting plate is fixed to the expansion tube pre-embedded in the wall by self-tapping screws, and the valve body assembly is fixed to the mounting plate by screws.

[0019] Furthermore, the handle is equipped with an indicator buckle to indicate its switching status.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] The valve body and water distribution core of this utility model are integrally injection molded from engineering plastics, which greatly reduces the cost of raw materials and machining. In particular, since the water distribution core is a plastic part, the electroplating process of the water outlet connector is eliminated. After machining, it can be directly installed on the water distribution core, which significantly improves production efficiency. Engineering plastics themselves do not rust and do not require surface treatment such as electroplating, avoiding the problem of coating peeling. They are more environmentally friendly and durable, especially suitable for the humid bathroom environment. Plastics are easy to mold, and more diverse and smooth appearance shapes and colors can be designed. The decorative cover further enhances the overall aesthetics and grade.
