Description

Technical Field

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

[0002] As the core control component of a faucet, the performance of the ceramic valve core directly affects the faucet's lifespan and user experience. Traditional ceramic valve cores often suffer from leaks and seepage due to inadequate sealing design during long-term use, wasting water resources and making disassembly and reassembly cumbersome.

[0003] A ceramic valve core has been disclosed in the prior art (application announcement number: CN112253795A). The structure of this ceramic valve core mainly includes an outer cylinder with an upward-opening cavity, and also includes key components such as a stationary ceramic disc, a moving ceramic disc, a support cover, and a valve stem. In the actual assembly process, the stationary and moving ceramic discs are first installed into the outer cylinder sequentially, and then the valve stem is installed. To secure these components, the design employs a mating mechanism between the support cover and the outer cylinder, ensuring that the stationary and moving ceramic discs, as well as the valve stem, are firmly positioned within the outer cylinder.

[0004] However, the aforementioned existing technology still has shortcomings. On the one hand, although this assembly method can achieve a certain degree of component fixation, its overall structural robustness remains significantly insufficient. Especially during actual use, external forces or long-term operation may cause components to loosen or shift position. On the other hand, impurities in tap water can adhere to the inner wall of the ceramic valve core, leading to damage. Therefore, to overcome these shortcomings and improve product stability and lifespan, improvements to the existing technology are necessary. Utility Model Content

[0005] The purpose of this utility model is to address the above problems. This utility model provides a ceramic valve core for faucets, which has the advantages of strong component fit and water flow that can wash away impurities from the inner wall of the ceramic.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ceramic valve core for a faucet, comprising an outer cylinder, the outer cylinder having a through connecting cavity, the connecting cavity having a first end and a second end, a bottom cover being installed at the first end of the connecting cavity, a stationary ceramic plate, a moving ceramic plate and a valve stem being sequentially arranged from the first end to the second end of the connecting cavity, the valve stem passing through the second end of the connecting cavity, the bottom cover having at least two hooks, the outer cylinder having corresponding locking holes, the outer cylinder and the bottom cover being detachably fixed together by the locking engagement between the hooks and the locking holes, the bottom cover having two oblique holes, the inner wall of the oblique holes having several oblique plates, a guide groove being formed between adjacent oblique plates, the stationary ceramic plate having two through holes corresponding to the oblique holes, and the moving ceramic plate having a water passage cavity communicating with the through holes.

[0007] Preferably, the ceramic tile is provided with mating grooves that correspond one-to-one with the hooks.

[0008] Preferably, the valve stem includes a rotating seat and a rotating column. The rotating column passes through the second end of the outer cylinder to the outside of the connecting cavity. The rotating seat is rotatably disposed in the connecting cavity. The moving ceramic plate is provided with a connecting groove, and the rotating seat is provided with a connecting block that mates with the connecting groove.

[0009] Preferably, a magnet is fixedly provided on the rotating base, the rotating base is provided with a mounting groove for installing the magnet, and the moving ceramic piece is provided with a clearance groove that corresponds to and cooperates with the mounting groove.

[0010] Preferably, the bottom cover is further provided with a positioning block, and the outer cylinder is provided with a positioning groove that cooperates with the positioning block.

[0011] Preferably, a limiting structure is provided between the rotating seat and the outer cylinder. The limiting structure includes a first limiting block disposed on the inner wall of the outer cylinder and a second limiting block disposed on the rotating seat. The first limiting block and the second limiting block are mutually limiting.

[0012] Preferably, a third limiting block is also provided on the inner wall of the outer cylinder, wherein a limiting step is provided on one of the second limiting blocks, and the third limiting block cooperates with the limiting step for limiting.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a ceramic valve core for a faucet. The combination of a hook and a locking hole makes the connection between the outer cylinder and the bottom cover more convenient and secure, and allows for easier replacement when the stationary ceramic disc, moving ceramic disc, or valve stem is damaged. Furthermore, when water enters through the inclined hole serving as the inlet, the flow channel creates micro-vortices. As the water flows through the gap between the inclined plates (i.e., the flow channel), it experiences drastic changes in direction and magnitude, forming localized turbulence and shear force. This unstable water flow effectively "stirs" and washes away tiny particles that may attempt to remain at the edge of the sealing surface. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-5As shown, a ceramic valve core for a faucet includes an outer cylinder 1 with a through connecting cavity 10. The connecting cavity 10 has a first end and a second end. A bottom cover 2 is installed at the first end of the connecting cavity 10. A stationary ceramic plate 4, a moving ceramic plate 5, and a valve stem 3 are sequentially arranged from the first end to the second end within the connecting cavity 10. The valve stem 3 passes through the second end of the connecting cavity 10. The bottom cover 2 has at least two hooks 21. The outer cylinder 1 has corresponding locking holes 11 that engage with the hooks 21. The bottom cover 2 also has a positioning block 22. The outer cylinder 1 has a positioning groove 12 that engages with the positioning block 22. A detachable fixed connection between the bottom cover 2 and the outer cylinder 1 is achieved through the engagement of the hooks 21 and the locking holes 11. The outer cylinder 1 and the bottom cover 2 are detachably fixed together through the engagement of the hooks 21 and the locking holes 11. The engagement of the positioning slot 12 and the positioning block 22 enables the positioning and installation of the outer cylinder 1 and the bottom cover 2. The engagement of the hook 21 and the locking hole 11 makes the connection between the outer cylinder 1 and the bottom cover 2 more convenient and secure. It also makes it easier to replace the static ceramic plate 4, the moving ceramic plate 5, or the valve stem 3 when they are damaged. The bottom cover 2 is provided with two inclined holes 20, one of which is a water inlet and the other is a water outlet. Several inclined plates 201 are provided on the inner wall of the inclined hole 20. A guide groove is formed between adjacent inclined plates 201. When the water flows in through the inclined hole 20, which serves as the water inlet, the water flow can generate a micro vortex under the action of the guide groove. When the water flows through the gap between the inclined plates 201 (i.e., the guide groove), it will generate a drastic change in direction and size, forming local turbulence and shear force. This unstable water flow can effectively "stir" and wash away tiny particles that may try to stay on the edge of the sealing surface.

[0018] It needs to be explained, such as Figure 3 As shown, in the assembled state, the central axis of the inclined hole 20 forms an angle with the central axis of the outer cylinder 1. In addition, the inclined plate 201 and the guide groove also form an angle with the central axis of the outer cylinder 1, thus enabling the incoming water flow to form a micro vortex.

[0019] The stationary ceramic plate 4 has two through holes that correspond one-to-one with the inclined holes 20. The through holes are a first water passage hole 41 and a second water passage hole 42. The first water passage hole 41 and the second water passage hole 42 are connected to the corresponding inclined holes 20. The moving ceramic plate 5 has a water passage cavity 53 that is connected to the first water passage hole 41. The water passage cavity 53 is configured such that when the moving ceramic plate 5 is in its initial state, the water passage cavity 53 is blocked from the second water passage hole 42. When the moving ceramic plate 5 rotates, the water passage cavity 53 is connected to the second water passage hole 42, thereby realizing the connection and blockage between the first water passage hole 41 and the second water passage hole 42, ensuring that the water flow at the inlet can flow smoothly out of the outlet.

[0020] The static ceramic tile 4 is provided with a mating groove 43 that corresponds to the hook 21. Through the mating groove 43 and the hook 21, the static ceramic tile 4 can be positioned and installed, and the static ceramic tile 4 and the bottom cover 2 can be prevented from rotating relative to each other in the assembled state.

[0021] The valve stem 3 includes a rotating seat 31 and a rotating column 32. The rotating column 32 passes through the second end of the outer cylinder 1 to the outside of the connecting cavity 10. The rotating seat 31 is rotatably disposed in the connecting cavity 10. The moving ceramic plate 5 is provided with a connecting groove 51. The rotating seat 31 is provided with a connecting block 36 that cooperates with the connecting groove 51. The cooperation between the connecting groove 51 and the connecting block 36 ensures that the rotating seat 31 and the moving ceramic plate 5 will not rotate relative to each other in the assembled state.

[0022] A limiting structure is provided between the rotating seat 31 and the outer cylinder 1. The limiting structure includes a first limiting block 33 disposed on the inner wall of the outer cylinder 1 and a second limiting block 13 disposed on the rotating seat 31. The first limiting block 33 and the second limiting block 13 cooperate to limit the maximum rotation angle of the valve stem 3.

[0023] A third limiting block 14 is also provided on the inner wall of the outer cylinder 1. One of the second limiting blocks 13 is provided with a limiting step 34. The third limiting block 14 and the limiting step 34 are matched to limit the axial movement of the rotating seat 31 in the outer cylinder 1.

[0024] A magnet is fixedly mounted on the rotating base 31, and the rotating base 31 is provided with a mounting groove 35 for mounting the magnet. The moving ceramic plate 5 is provided with a clearance groove 52 that corresponds to and cooperates with the mounting groove 35. The magnet can magnetically cooperate with the detection element outside the water purification valve core and make the detection element generate an induction signal. The detection element is a Hall element, which is set on the faucet. The water purification valve core is set inside the faucet. The faucet is also provided with an indicator light that cooperates with the Hall element. Specifically, turning the faucet switch drives the rotating column 32 to rotate, which in turn drives the rotating base 31 to rotate. When the rotating base 31 rotates to a set angle, the Hall element can accurately detect the change in magnetic field and output an induction signal to trigger the control circuit, so that the indicator light is lit. During the process of water flowing from the faucet, the indicator light can effectively play a prompting role, so that the user can intuitively understand the use status of the faucet.
