Description

Technical Field

[0001] This application relates to the field of valve core technology, and in particular to a faucet valve core. Background Technology

[0002] Faucets have become an indispensable part of daily life, mostly serving as control devices for manually controlling the flow of water at the outlet of a water channel. Their development is inseparable from human wisdom and technological progress. With the development of faucets, their structure has become increasingly complex, with more and more components. Among these, the valve core occupies a crucial "heart" position, and the quality and performance of a faucet are largely characterized by the valve core. In existing technology, the valve core includes a valve stem, a linkage bracket, a moving valve plate, a stationary valve plate, a housing, and a valve seat. The valve stem is rotatably connected to the upper end of the housing, and one end of the valve stem is inserted into... The valve core is inserted into the linkage bracket and drives the linkage bracket to move. The moving valve plate is installed on the linkage bracket, and the stationary valve plate is installed on the valve seat. The moving valve plate and the stationary valve plate move relative to each other. The housing and the valve seat are installed and fixed by snaps or bolts and nuts. When the faucet is operated for a long time, the water in the faucet will contain particulate impurities such as mud and sand. Subsequently, the impurities in the water will become embedded in the gaps inside the valve core. These impurities will affect the sensitivity of the internal parts of the valve core, so the valve core needs to be disassembled and cleaned. However, the housing and the valve seat are installed and fixed by snaps or bolts and nuts, which makes the disassembly of the valve core inefficient. Utility Model Content

[0003] The purpose of this utility model is to provide a faucet valve core that addresses the defects and shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The device includes a housing and a valve seat, which are installed in contact with each other. The valve seat is provided with at least two fixing members evenly distributed around its circumference. Each fixing member includes a rotating plate and a fixing plate. One end of the fixing plate is located at one end of the fixing plate, and the other end of the fixing plate is rotatably connected to the valve seat. The fixing plate is fastened and fixed to the housing.

[0005] Preferably, the side wall of the rotating plate is provided with a locking plate, which is inserted into the side wall of the housing.

[0006] Preferably, the upper end face of the housing is provided with a fixing groove for the fixing plate to be inserted and fixed.

[0007] Preferably, the side wall of the housing is provided with a connecting groove for the rotating plate to be embedded, and the connecting groove is in communication with the fixing groove.

[0008] Preferably, the side wall of the fixing plate is provided with a snap-fit ​​block, and the housing is provided with a snap-fit ​​groove on the inner side wall of the fixing groove for snap-fit ​​block to snap-fit ​​and fix.

[0009] Preferably, a toggle plate is rotatably connected to the fixed plate.

[0010] Preferably, a torsion spring is fitted on the rotating shaft of the actuating plate, and the torsion spring drives the actuating plate to approach the fixed plate.

[0011] Preferably, one end of the actuating plate is provided with a pull strap.

[0012] In summary, this application includes at least one of the following beneficial technical effects: 1. When the valve core needs to be disassembled, simply rotate the rotating plate to detach the fixing plate from the housing. Then the housing can be removed from the valve seat. After that, the parts inside the housing can be taken out and cleaned to remove mud, sand and other particulate impurities. Then the valve core can be assembled in sequence. After that, rotate the rotating plate in the opposite direction to make the fixing plate snap onto the housing, thereby fixing the housing and the valve seat. According to the above disassembly process, the work efficiency of disassembling the valve core is improved. 2. When the rotating plate needs to be rotated, simply hold the pull strap, then drive the actuating plate to rotate, and then rotate the fixing component through the actuating plate, which improves the convenience of driving the fixing component.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] This application discloses a faucet valve core.

[0017] Reference Figure 1 and Figure 2It includes a housing 1, a valve seat 2, a valve stem 3, a linkage bracket 4, a moving valve plate 5, and a stationary valve plate 6. The linkage bracket 4 is installed inside the housing 1. The valve stem 3 is rotatably connected to the linkage bracket 4. The upper end face of the moving valve plate 5 has a drive hole. One end of the valve stem 3 is inserted into the drive hole. The stationary valve plate 6 is fixed on the valve seat 2. When the valve stem 3 rotates, the lower end of the valve stem 3 can drive the moving valve plate 5 to move.

[0018] The upper end face of the valve seat 2 is uniformly and integrally provided with three insert blocks 7. The outer peripheral side wall of the lower end of the housing 1 is uniformly provided with three slots 8. The insert blocks 7 are inserted into the slots 8. The insert blocks 7 are provided with fixing members 9. The fixing members 9 include a rotating plate 11 and a fixing plate 10. One end of the rotating plate 11 is rotatably connected to the upper end face of the insert block 7. One end of the fixing plate 10 is integrally provided on the side wall of the upper end of the rotating plate 11. The longitudinal section of the fixing member 9 is "L" shaped.

[0019] Reference Figure 2 and Figure 3 The outer peripheral sidewall of the housing 1 is provided with three connecting grooves 12 evenly distributed around the periphery, and the upper end face of the housing 1 is provided with three fixing grooves 13 evenly distributed around the periphery. The fixing grooves 13 are connected to the connecting grooves 12. The rotating plate 11 is located in the connecting groove 12, and the fixing plate 10 is located in the fixing groove 13.
