Technical Field

[0001] This utility model relates to the field of concealed valve bodies in shower systems, specifically to a splicable concealed valve body assembly and a concealed shower device. Background Technology

[0002] In shower systems, concealed valve bodies typically control the water flow from different outlets such as faucets and showerheads. Currently, the water circuit components in concealed valve bodies are usually a single, integrated structure, making it difficult to flexibly assemble to accommodate varying numbers of outlets and thus challenging complex installation scenarios. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned defects or problems in the background technology, and to provide a splicable concealed valve body assembly and a concealed shower device. The splicing scheme expands the functions, enriches the usage scenarios, and solves the technical problems.

Corresponding to the third valve connection and valve core of the third water outlet, the third water inlet is provided with a third water inlet channel, the third water outlet is provided with a third water outlet channel, and the third connecting part is provided with a third water passage channel. The third water passage channel connects the third water inlet channel, the third water outlet channel, and the third water passage channel. The third valve connection is connected to the valve core to control the flow of water in the corresponding third water outlet channel. When there is no third water passage component, the second connecting part is inserted into the plug to block the second water passage channel. When a third water passage component is assembled, the third water inlet is inserted into the second connecting part. The plug is inserted into the third connecting part to block the third water passage channel. When multiple third water passage components are assembled, the third water passage component is inserted into the third water inlet of another third water passage component through the third connecting part. The plug blocks the third connecting part of the third water passage component furthest from the first water passage component.

[0006] The second technical solution is based on the first technical solution. The first water-passing component is further provided with a first water inlet, a first valve connection, and a valve core. The first water inlet is provided with two first water inlets. One of the two first water inlets and the first water outlet are respectively located at both ends of the first water-passing component along the first direction and open outwards at both ends. The first valve connection is used to connect a valve core suitable for switching the communication between the two first water inlets and the first water outlet. The second water inlet and the second water passage are respectively located at both ends of the second water-passing component along the first direction and open outwards at both ends. The second water outlet is arranged side by side along the first direction. The second water outlet opens along a second direction perpendicular to the first direction.

[0007] The third technical solution is based on the first and second technical solutions. The second water-passing component further includes a fourth valve connection part near the second water inlet. The fourth valve connection part is adapted to connect with the valve core to adjust the flow rate of the second water passage.

[0008] The fourth technical solution is based on the first technical solution. The first water outlet, the second connecting part and the third connecting part are constructed into a first shape, and the second water inlet and the third water inlet are constructed into a second shape. The diameter of the first shape is larger than the diameter of the second shape, and the second shape is adapted to be inserted into the first shape and heat-fused together.

[0009] The fifth technical solution is based on the first to fourth technical solutions, wherein the first water inlet component, the second water inlet component, and the third water inlet component are integrally injection molded by PPR.

[0010] The sixth technical solution is based on the first to third technical solutions, and it also includes a metal sleeve, which is sleeved at the connection between the first valve connection, the second valve connection, the third valve connection, the fourth valve connection and the valve core.

[0011] The seventh technical solution is based on the first technical solution and further includes a housing and a dust cover. The housing surrounds the first water-passing component and the second water-passing component, and the housing has a first through hole corresponding to the first water inlet and the second water outlet. When the third water-passing component is assembled, the housing surrounds the first water-passing component, the second water-passing component, and the third water-passing component, and the housing has a first through hole corresponding to the first water inlet, the second water outlet, and the third water outlet for connecting hot and cold water pipes and water outlet terminal pipes. The dust cover is independently sleeved on the outside of the operating end of each valve core, and the bottom of the dust cover is snapped into the housing to protect the valve core.

[0012] The eighth technical solution relates to a concealed shower device, which includes a decorative panel. The decorative panel has valve core through holes and operating parts that are the same number as the number of valve cores. The valve core through holes correspond to the valve cores so that the valve cores can pass through. The operating parts correspond to the operating end of a valve core and are used by the user to operate the valve cores.

[0013] As can be seen from the above description of the various embodiments of the present utility model, compared with the prior art, the various embodiments of the present utility model have the following beneficial effects:

[0014] 1. In the first technical solution, the splicing scheme of the concealed valve body assembly can be a combination of a first water passage component, a second water passage component, and a plug; it can be a combination of a first water passage component, a second water passage component, a third water passage component, and a plug; or it can be a combination of a first water passage component, a second water passage component, multiple third water passage components, and a plug. This solution divides the traditional single-structure water circuit assembly into small, splicable modules. Through a plug-in design, multiple water passage components can be spliced ​​together to adapt to the needs of controlling different numbers of water outlet terminals. The plug seals the water passage of the last water passage component, thus perfecting the concealed valve body assembly.

[0015] 2. In the second technical solution, the existing hot and cold water pipes are connected to the first water-passing component, and the hot and cold water are mixed through the first water-passing component to achieve the flow of warm water out of the shower valve system; one inlet channel of the second water-passing component is arranged in a straight line with the water passage to form a main channel without bends, reducing water flow resistance and pressure loss; the water outlet is opened perpendicular to the first direction to avoid direct collision with the main water flow, reducing pressure fluctuations caused by cross interference; the valve connection part is located in a position suitable for valve body installation, perpendicular to the overall water circuit, and convenient for users to press the switch to open and close the water circuit when in use.

[0016] 3. In the third technical solution, the flow control valve is installed near the second water inlet to control the water flow through the water channel. It is close to the water inlet position to reduce the water flow lag effect and is decoupled from the on / off valve to avoid mutual interference.

[0017] 4. In the fourth technical solution, the two-shaped structure facilitates insertion, reduces installation difficulty, improves construction efficiency, and the hot-melt connection avoids the risk of aging of the sealing ring.

[0018] 5. In the fifth technical solution, PPR material can avoid problems such as pipe aging and corrosion, while PPR one-piece injection molding enhances the anti-seepage and anti-leakage functions.

[0019] 6. In the sixth technical solution, compared with metal parts, PPR material is not as strong as metal parts in terms of pressure resistance. Therefore, a reinforcement structure is designed to reinforce the valve connection through a metal sleeve to prevent PPR from cracking.

[0020] 7. In the seventh technical solution, the dust cover can prevent dust, cement and other substances from entering the valve core and causing damage to the valve core. At the same time, the independent cover can avoid affecting other valve bodies.

[0021] 8. In the eighth technical solution, the panel can hide the complex valve body structure, making the overall appearance more beautiful and the operation part easier for users to operate; after the panel is removed, the valve core can be directly exposed without breaking through the wall for maintenance.
