Description

Technical Field

[0001] This utility model relates to the field of valve core technology, and more specifically, to a multifunctional valve core. Background Technology

[0002] Currently, valve cores typically control water output through the cooperation of a stationary valve plate assembly, a moving valve plate, and a valve stem. Sufficient space is provided within the valve body for the movement of the valve stem and moving valve plate. For example, patent CN217951302U discloses a swing-type temperature-regulating valve core, in which a valve plate, a moving valve plate assembly, and a valve stem are housed within the valve housing. The lower end of the valve stem is constrained to the moving valve plate assembly, and water output control is achieved by swinging the valve stem to move the moving valve plate assembly left and right. However, during long-term use, under alternating hot and cold conditions, gaps can easily appear between the valve stem and the valve housing due to temperature fluctuations, affecting the valve core's sealing performance and causing end leakage.

[0003] In view of this, the applicant hereby submits this application after studying the existing technology. Utility Model Content

[0004] This invention provides a multifunctional valve core, which aims to improve at least one of the above-mentioned technical problems.

The valve body has a cavity with an opening at the upper end. A stationary valve plate assembly and a moving valve plate assembly are disposed within the cavity. The valve stem has a ball head, which is rotatably connected to the cavity. The upper end of the valve stem extends out of the opening, and the lower end is connected to the moving valve plate assembly, so that when the valve stem rotates, it can drive the moving valve plate assembly to move to control water output. A sealing assembly is provided between the moving valve plate assembly and the opening. The sealing assembly has a through hole with an arc surface. The ball head is at least partially placed in the through hole. The sealing assembly can tightly fit the inner wall of the cavity and the arc surface of the ball head to seal the upper end of the cavity.

[0006] As a further optimization, the sealing assembly includes a sealing ring and a clamping member, the sealing ring being located on the side near the opening and being clamped by the clamping member.

[0007] As a further optimization, the sealing ring is made of soft rubber material.

[0008] As a further optimization, the movable valve plate assembly includes a mating movable plate and a movable plate cover, with the valve stem connected to the movable plate cover.

[0009] As a further optimization, the moving piece is provided with slots on both sides, and the moving piece cover is provided with buckles on both sides. The moving piece and the moving piece cover are connected by the slots and the buckles.

[0010] As a further optimization, the valve body sidewall is provided with several water inlets and the bottom is provided with several water outlets. The stationary valve plate assembly is provided with several water distribution holes for connecting the water inlets and the water outlets respectively. The valve stem drives the moving valve plate assembly to move and selectively block the water distribution holes, thereby realizing water output control.

[0011] As a further optimization, a bottom cover is connected to the bottom of the valve body, the water outlet is located on the bottom cover, and the static valve plate assembly is fixedly connected to the bottom cover.

[0012] As a further optimization, two limiting parts are provided opposite to each other on the top surface of the opening, and a channel is formed between the two limiting parts to allow the valve stem to swing along the length direction of the channel.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example

[0024] Depend on Figures 1 to 4 As shown, this utility model embodiment provides a multifunctional valve core, including a valve body 1 and a valve stem 2. The valve body 1 has a cavity 11 with an opening 12 at the upper end. A stationary valve plate assembly 3 and a moving valve plate assembly 4 are provided in the cavity. The valve stem 2 has a ball head 21, which is rotatably connected to the cavity 11. The upper end of the valve stem 2 extends out of the opening 12, and the lower end is connected to the moving valve plate assembly 4, so that when the valve stem 2 rotates, it can drive the moving valve plate assembly 4 to move to control the water output. A sealing assembly 5 is provided between the moving valve plate assembly 4 and the opening 12. The sealing assembly 5 has a through hole with an arc surface. The ball head 21 is partially or completely placed in the through hole. The sealing assembly 5 can tightly fit the inner wall of the cavity 11 and the arc surface of the ball head 21 to seal the upper end of the cavity.

[0025] In this embodiment, a sealing component 5 is provided between the moving valve plate assembly 4 and the opening 12. The outer surface of the sealing component 5 is tightly fitted to the inner wall of the cavity 11, and the arc surface of the through hole is tightly fitted to the arc surface of the ball head 21, thereby sealing the upper end of the valve body. This prevents water leakage caused by gaps between the valve stem and the valve body housing due to temperature changes, thus improving the sealing performance of the valve body. At the same time, it can also prevent water leakage caused by wear between the valve stem and the valve body housing, extending the service life of the valve core.

[0026] Specifically, the sealing assembly includes a sealing ring 51 and a clamping member 52. The sealing ring 51 is located on the side near the opening 12. The top of the cavity 11 has an annular support surface, and the sealing ring 51 abuts against the annular support surface. The inner wall of the cavity 11 near the moving valve plate assembly 4 has a stepped structure, and the clamping member 52 is fitted into the stepped structure, thereby pressing the sealing ring 51 tightly against the support surface. At the same time, the clamping member 52 restricts the moving valve plate assembly 4 between itself and the stationary valve plate assembly 3, so that the moving valve plate assembly 4 always adheres to the stationary valve plate assembly 3 when it moves. The sealing ring 51 is made of a soft rubber material with good temperature resistance and wear resistance, such as rubber or silicone.

[0027] Reference Figure 4 As shown, the movable valve plate assembly 4 includes a movable plate 41 and a movable plate cover 42 that engage with each other. The movable plate 41 has slots 43 on both sides, and the movable plate cover 42 has buckles 44 on both sides. The movable plate 41 and the movable plate cover 42 are connected by the slots 43 and the buckles 44. The movable plate cover 42 has a mounting groove, and the bottom end of the valve stem 21 is connected to the mounting groove.

[0028] The valve body 1 has several inlets 13 on its side wall and several outlets 14 at its bottom. The stationary valve plate assembly 3 has several water distribution holes 31 for connecting the inlets 13 and outlets 14 respectively. The valve stem 2 drives the moving valve plate assembly 4 to selectively block the water distribution holes 31, thereby achieving water output control. A bottom cover 15 is connected to the bottom of the valve body 1, and the outlets 14 are located on the bottom cover 15. The stationary valve plate assembly 3 is fixedly connected to the bottom cover 15.

[0029] In another preferred embodiment, two limiting portions 16 are disposed opposite each other on the top surface of the opening 12, forming a channel between the two limiting portions 16 to allow the valve stem 2 to swing along the length of the channel. This embodiment restricts the rotation direction of the valve stem 2 by using the two limiting portions 16, ensuring that the valve stem 2 can only swing left and right.

[0030] Furthermore, one of the limiting parts 16 has two limiting grooves 17 on its inner side. The valve stem 2 has a mounting hole 22 on the side near the limiting part 16. A spring 23 and a ball bearing 24 are installed in the mounting hole. When the valve stem 2 swings to the position of either limiting groove 17, the ball bearing 24 can be ejected by the spring 23 and strike the side wall of the limiting groove 17 to make a sound, thus reminding the user. Preferably, the two limiting grooves 17 are located at the maximum angle of the valve stem 2 swinging to the left and right, respectively. The sound produced by the ball bearing 24 striking the side wall of the limiting groove 17 reminds the user that the valve core is completely closed or the water flow is at its maximum, or that cold water is flowing out completely or the water temperature is at its highest.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
