Description
- This application claims priority to Chinese Patent Application 202221265593.0, filed on May 24, 2022, which is incorporated herein by reference.
- The present invention relates to the field of shower faucets, in particular to a valve element cover plate and shower faucet made thereof.
- Shower faucets are widely used in bathrooms. A concealed shower faucet is entirely installed in the wall, so a detachable cover plate is separately arranged for the sake of easy installation, and valve elements as well as other components are installed together on the cover plate body. It mainly comprises a cover plate body for installing valve elements and setting water channels between the valve elements, and a water distribution box embedded in the wall. When fixing, directly press the cover plate body to the bottom of the inner cavity of the concealed water distribution box, and install a sealing ring between the contact surfaces of the two components to achieve sealing effect. However, the cover plate body is prone to deformation under the action of water pressure, and slight deformation would weaken the sealing effect between the two, resulting in water leakage.
- In order to solve the above problems, the present invention provides a valve element cover plate and shower faucet made thereof which has good sealing effect, and can maintain good sealing performance even when the cover plate body is deformed, and also has good filtering effect, easy to maintain, and can effectively reduce the wear of downstream switching valve elements, improve the service life of the valve elements and avoid blockage at the water outlets.
- To solve the above problems, the present invention adopts the following technical scheme: a valve element cover plate, comprising a cover plate body. The cover plate body is provided with a water mixing valve mounting position and at least one switching valve mounting position. A cold water inlet and a hot water inlet connected to the water mixing valve mounting position, and water outlets corresponding to the switching valve mounting positions are arranged on the back of the cover plate body. The cold water inlet, the hot water inlet and the water outlets protrude outwards away from the front side of the cover plate body. The cold water inlet, the hot water inlet and the outer cylindrical wall of the water outlets are provided with sealing rings; a water diverting channel connected in series with each switching valve mounting position is arranged in the cover plate body. A mixed water channel connected to the water diverting channel is arranged in the water mixing valve mounting position; fixing parts are arranged on the side of the cover plate body.
- The above structure shows that the sealing is achieved by changing traditional end-face sealing structure into protruding structure, that is, allow the cold water inlet, the hot water inlet and the water outlets to protrude outwards, and then arrange sealing rings on their outer cylindrical walls. When finally connecting to the concealed water distribution box, insert them into the corresponding connectors of the concealed water distribution box to improve the sealing effect. Even when the cover plate body is deformed, a sufficient axial allowance from connecting and inserting can ensure the sealing effect, so it can still maintain a good sealing performance in a high-pressure water environment; the cold water inlet and the hot water inlet are used to supply cold water and hot water respectively. After being mixed by the water mixing valve element in the water mixing valve mounting position, the water is discharged through the mixed water channel to the downstream. When the water enters the diverting channel, the switching valve elements in each switching valve mounting position control the on-off of their respective water outlets; fixing parts are arranged on the side of the cover plate body for connecting the concealed water distribution box during installation.
- Further, the present invention proposes that the cover plate body is provided with a filter mounting position, and the mixed water channel is connected to the water diverting channel through the filter mounting position.
- The above structure shows that the mixed water is filtered by the filter and debris such as scale will not enter the switching valve elements to avoid wear and blockage at the downstream water outlets; since the filter is installed at the downstream of the water mixing valve element, and the user only needs to close the water mixing valve element when replacing or cleaning the filter without turning off the indoor water main, which effectively improves the convenience of cleaning or replacing the filter.
- Further, the present invention proposes that a mixed water outlet connected to the filter mounting position and a mixed water inlet connected to the upstream of the water diverting channel are arranged on the back of the cover plate body; the filter mounting position is connected to the mixed water inlet through the mixed water outlet and the external pipeline and then connected to the water diverting channel; the mixed water outlet and the mixed water inlet protrude outwards away from the front side of the cover plate body; sealing rings are arranged in the mixed water outlet and on the outer cylindrical wall of the mixed water inlet.
- The above structure shows that the mixed water channel is connected to the inner cylindrical wall of the filter mounting position, and the mixed water outlet is connected to the bottom of the filter mounting position. The filter is a cylindrical filter screen (where the mixed water is filtered after flowing through the mixed water channel, from the outer cylindrical wall of the filter towards the center of the filter, then discharged from the mixed water outlet) and the mixed water outlet is connected to the mixed water inlet through the external pipeline; the above structure is designed for easily demolding the cover plate body when it is produced by injection molding, and arranging the filter; the mixed water outlet and the mixed water inlet also protrude outwards to ensure the sealing effect.
- Further, the present invention proposes that the cover plate body is provided with a hydroelectric generator mounting position, and the mixed water inlet is connected to the water diverting channel through the hydroelectric generator mounting position.
- The above structure shows that the mixed water enters the hydroelectric generator mounting position through the mixed water inlet and then flows to the water diverting channel.
- Further, the present invention proposes that a hydroelectric generator is arranged in the hydroelectric generator mounting position.
- The above structure shows that the water flows from the rear end face of the hydroelectric generator to the side wall of its middle section during operation, so the mixed water inlet is arranged at the bottom of the hydroelectric generator mounting position to enable the water to effectively wash the impellers of the hydroelectric generator and flow to the downstream through the water diverting channel connected to the inner cylindrical wall of the hydroelectric generator mounting position.
- Further, the present invention proposes that a display module is arranged outside the hydroelectric generator in the hydroelectric generator mounting position.
- The above structure shows that the display module is electrically connected to the hydroelectric generator for displaying information such as water temperature and flow rate, and the hydroelectric generator is provided with a temperature sensor.
