Description

Technical Field

[0001] This application relates to the field of valve cores, and more particularly to a valve core and a water distribution valve. Background Technology

[0002] In existing technologies, diverter valve cores, as key components for water flow distribution and control, are widely used in various water systems, such as shower equipment, washing machines, and household water supply and drainage systems. However, traditional diverter valve cores typically switch water flow paths by directly blocking the original water flow channel and opening a new one. This process inevitably leads to a sudden and complete interruption of water flow, creating a noticeable interruption. This design not only affects the continuity and comfort of the user experience, especially in scenarios requiring a smooth water flow transition, such as adjusting water temperature and volume while showering, where abrupt changes in water flow can cause discomfort; furthermore, frequent water flow interruptions can cause unnecessary stress on the piping system, potentially damaging the lifespan of pipes and connecting components in the long run.

[0048] This application provides a valve core, which includes a housing 100, a switching component 200, a stationary component 300, and a drive assembly 400.

[0049] The housing 100 forms a receiving cavity, and a water inlet groove 500 is provided on the outer wall of the housing 100. The water inlet groove 500 communicates with the receiving cavity. The switching member 200 is located in the receiving cavity and has a switching hole 210 that passes through it. The stationary member 300 is located in the receiving cavity and has multiple water outlet holes 310 that pass through it. The water outlet holes 310 communicate with the outside of the housing 100. The driving assembly 400 is rotatably mounted on the housing 100 and is drively connected to the switching member 200. The driving assembly 400 is used to drive the switching member 200 to rotate. When the switching hole 210 is located in the middle position of two adjacent water outlet holes 310, the switching hole 210 is at least partially connected to the two adjacent water outlet holes 310.

[0050] See Figure 1 , Figure 2 as well as Figure 3 As shown, this application drives the switching member 200 to rotate relative to the stationary member 300 through the driving component 400, thereby changing the position between the switching hole 210 and each water outlet 310. During the rotation of the switching member 200, the switching hole 210 can be made to coincide with different water outlets 310 to achieve communication, thereby allowing water entering the switching hole 210 to flow out from the water outlet 310 that is connected to it.

[0051] Please continue reading. Figure 1 and Figure 2 As shown, water enters the switching hole 210 from the inlet tank 500. The water flows outward through the channel formed by the switching hole 210 and the outlet hole 310, thereby realizing the switching of water delivery to different positions of the switching hole 210.

[0052] Please see Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown, in the initial state, the switching hole 210 is only connected to one of the water outlet holes 310. Figure 6 As shown, the surface of the stationary component 300 facing the switching component 200 is provided with multiple blocking portions 320. Each blocking portion 320 is located between two adjacent water outlets 310. When the switching component 200 rotates, the switching hole 210 gradually moves towards one of the blocking portions 320. When the switching hole 210 rotates to the position between two adjacent water outlets 310, that is, when it coincides with the position of the blocking portion 320, the switching hole 210 partially connects with the two adjacent water outlets 310. Figure 7 As shown in the figure, the water flow remains continuous during the switching process, achieving a smooth switching and thus improving the user experience.

[0053] Please see Figure 2 , Figure 5As shown, there is a gap between the switching member 200 and the inner wall of the accommodating cavity. The shielding part 320 is a groove that communicates with the circumferential surface of the stationary member 300. The groove communicates with the gap between the switching member 200 and the inner wall of the accommodating cavity. When the switching hole 210 coincides with the shielding part 320, the shielding part 320 will not suddenly block the water from the switching hole 210. A small part of the water will be transported out through the channel that connects the switching hole 210 and the two water outlet holes 310. The other part will achieve pressure balance through the channel formed by the groove and the gap, preventing the shielding part 320 from being impacted.

[0054] For example, there are three water outlets 310 and three shielding parts 320, and they are evenly distributed about the center of the stationary part 300. The size and shape of the water outlets 310 and the shielding parts 320 are not limited here. In this embodiment, the shape of the water outlets 310 and the shielding parts 320 is approximately fan-shaped.

[0055] The housing 100 includes a base 110 and an outer shell 120. The base 110 and the outer shell 120 are detachably connected. The base 110 has a through hole 111 that passes through it. The position of the through hole 111 is the same as and communicates with the water outlet 310. The base 110 and the outer shell 120 define a receiving cavity. The water inlet groove 500 is formed on the outer wall of the outer shell 120.

[0056] Please see Figure 1 , Figure 2 as well as Figure 8 As shown, in order to facilitate the outflow of water entering the outlet hole 310, through holes 111 are made through the bottom surface of the base 110. The number and position of through holes 111 are the same as those of the outlet hole 310. The outlet hole 310 is connected to the outside through through holes 111. The shape of through holes 111 can be the same as or different from that of the outlet hole 310, as long as water from the outlet hole 310 can flow out.

[0057] For example, there are three through holes 111, and the through holes 111 are circular in shape.

[0058] Furthermore, in order to prevent water leakage at the connection between the water outlet 310 and the base 110, a sealing ring can be installed at the connection between the water outlet 310 and the base 110 to achieve a seal.

[0059] The shell 100 further includes a connecting structure 130, which includes a plurality of first positioning grooves 131 formed on the outer peripheral surface of the stationary part 300, a locking block 132 and a second positioning block 134 provided on the outer peripheral surface of the base 110, a locking groove 135 formed on the outer wall of the outer shell 120, a first positioning block 133 provided on the side of the second positioning block 134 near the center direction of the outer shell 120, a second positioning groove 136 formed on the end face of the outer shell 120 facing the base 110, the locking block 132 passing through the first positioning groove 131 to engage with the locking groove 135, and the first positioning block 133 passing through the first positioning groove 131.

[0060] See Figure 3 As shown, the first positioning groove 131 is formed on the outer peripheral surface of the stationary part 300. There can be multiple first positioning grooves 131, which are not limited here and can be designed according to actual needs. For example, there are three first positioning grooves 131 and two locking blocks 132, which are evenly arranged about the center of the base 110. During assembly, the locking blocks 132 will pass through the first positioning grooves 131. The positioning of the stationary part 300 is achieved by the locking action of the locking blocks 132 and the first positioning grooves 131. The locking blocks 132 will pass through the first positioning grooves 131 to the locking slot 135. The locking blocks 132 and the locking slot 135 will engage to achieve the connection between the base 110 and the outer shell 120. That is to say, the locking blocks 132 can not only achieve the positioning of the stationary part 300, but also achieve the connection between the base 110 and the outer shell 120.

[0061] In one embodiment, in order to make the connection between the base 110 and the outer shell 120 more stable, the second positioning block 134 on the circumferential surface of the base 110 will extend into the second positioning groove 136, thereby fixing the position between the base 110 and the outer shell 120.

[0062] In one embodiment, a first positioning block 133 is provided on the inner side of one or all of the second positioning blocks 134. When the locking block 132 is inserted into the first positioning groove 131, the first positioning block 133 will also be inserted into the first positioning groove 131 at other locations, thereby further realizing the positioning of the stationary part 300.

[0063] The area of ​​the switching hole 210 is greater than or equal to the area of ​​the water outlet hole 310. The switching hole 210 includes a water inlet 211, a first connecting part 212 and a second connecting part 213. The water inlet 211 is opened through the switching member 200 along a first direction. The first connecting part 212 is opened on the side of the water inlet 211 near the center of the switching member 200. The second connecting part 213 is opened on the side of the water inlet 211 away from the center of the switching member 200.

[0064] Please see Figure 4 As shown, the area of ​​the switching hole 210 should be larger than the area of ​​the outlet hole 310, so that it can surround the entire outlet hole 310 and allow enough water to enter the outlet hole 310 through the switching hole 210.

[0065] See Figure 4 as well as Figure 13 As shown, in one embodiment, the three water outlets 310 can be labeled as position a, position b, and position c. In the initial state, the switching hole 210 coincides with the water outlet 310 at position a. The switching hole 210 consists of three parts: a water inlet 211, a first connecting part 212, and a second connecting part 213. During rotation, in order to allow enough water to enter the water outlet 310 at position a, a second connecting part 213 is provided on the side of the water inlet 211 away from the center of the switching member 200. The second connecting part 213 is recessed along the rotation direction.

[0066] like Figure 13 As shown, during the rotation of the switching hole 210 from position a to position b, the second connecting part 213 gradually connects with the water outlet 310 at position a, thereby ensuring that enough water enters the water outlet 310 at position a. Then, as the switching member 200 continues to rotate, as... Figure 7 as well as Figure 13 As shown, when the switching hole 210 reaches the blocking part 320, the first connecting part 212 is partially connected to the water outlet 310 at position a and partially connected to the water outlet 310 at position b. That is, water will enter the water outlet 310 at position a and the water outlet 310 at position b. That is, there will be no water interruption during the switching process. As the switching member 200 continues to rotate, the switching hole 210 will gradually move to the water outlet 310 at position b, thereby completing the switching. When the switching hole 210 needs to switch from position b to position c, the switching process is the same as above, and will not be described in detail here.

[0067] See Figure 13 As shown in this embodiment, when the switching hole 210 rotates from position a to position b, the area of ​​the water outlet 310 at position a connected with the switching hole 210 gradually decreases, while the area of ​​the water outlet 310 at position b connected with the switching hole 210 gradually increases. In other words, the switching from position a to position b is a gradual transition, and there will be no sudden disconnection of the water outlet 310 at position a and the switching hole 210 at position b, which would cause a sudden interruption of flow, nor will there be a sudden connection of the water outlet 310 at position b and the switching hole 210, which would cause a sudden outflow of water. The transition between disconnection and connection is smoother throughout the entire switching process.

[0068] The drive assembly 400 includes a drive member 410, a transmission member 420, and a transmission structure 430. The drive member 410 is rotatably mounted on the housing 100, and part of the drive member 410 extends into the receiving cavity. The transmission member 420 is disposed inside the receiving cavity and is connected to the switching member 200. The transmission structure 430 is used for power transmission between the drive member 410 and the transmission member 420.

[0069] See Figure 2 , Figure 3 As shown, in one embodiment, the driving member 410 is a shaft. By rotating the driving member 410, the transmission member 420 can be driven to rotate. Since the transmission member 420 and the switching member 200 are connected by a transmission structure 430, the rotational force from the driving member 410 can be applied to the switching member 200 through the transmission member 420, thereby driving the switching member 200 to rotate, and thus realizing the switching connection between the switching hole 210 and each water outlet hole 310.

[0070] The driving component 410 includes a driving rod 411. At least one mounting groove 412 is provided on the outer peripheral surface of the driving rod 411. A sealing element 413 is provided in the mounting groove 412. The driving rod 411 has a stepped surface, and a gasket 414 is provided on the surface of the stepped surface.

[0071] Please see Figure 2 , Figure 3 as well as Figure 12 As shown, the drive rod 411 is coaxial with the housing 120. The housing 120 has a shaft hole (not shown in the figure) that communicates with the accommodating cavity. The drive rod 411 is rotatably mounted on the shaft hole, with part extending into the accommodating cavity and part located outside the housing 120. To improve the sealing between the drive rod 411 and the shaft hole, at least one mounting groove 412 is formed on the outer circumferential surface of the drive rod 411. A seal 413 is installed in each mounting groove 412, and a gasket 414 is provided on the stepped surface of the drive rod 411. The gasket 414 is located between the stepped surface and the top wall of the accommodating cavity.

[0072] For example, there are two mounting slots 412 and two seals 413, and the gasket 414 can be made of an elastic material such as rubber.

[0073] The transmission component 420 includes a driven component 421. The end face of the driven component 421 facing the switching component 200 is provided with a plurality of abutting blocks 422. The edge of the abutting block 422 facing the switching component 200 is provided with a transmission block 423. The end face of the switching component 200 facing the driven component 421 is provided with a second transmission groove 700. The transmission block 423 extends into the second transmission groove 700.

[0074] See Figure 2 , Figure 3 , Figure 9 as well as Figure 10 As shown, the abutting block 422 abuts against the upper surface of the switching member 200, and the space formed between two adjacent abutting blocks 422 is connected to the water inlet tank 500. In order to transmit the power from the driven member 421 to the switching member 200, the transmission block 423 extends into the second transmission groove 700 on the switching member 200. The transmission block 423 and the second transmission groove 700 cooperate to achieve a snap-fit ​​transmission. Each transmission block 423 has a protrusion 424 on both sides. After the transmission block 423 extends into the second transmission groove 700, the protrusion 424 abuts against the side wall of the second transmission groove 700, so that the power can be transmitted to the switching member 200 in the first time interval, preventing the gap between the transmission block 423 and the side wall of the second transmission groove 700.

[0075] In one embodiment, the bottom surface of the abutment block 422 is provided with a cavity 425. By reducing the amount of material used at the location of the cavity 425, the production cost can be reduced to a certain extent.

[0076] For example, there are three abutment blocks 422 and three second transmission grooves 700, and they are all evenly spaced.

[0077] The transmission structure 430 includes a protrusion 432 disposed on the end face of the driving member 410 facing the transmission member 420. The end face of the transmission member 420 facing the driving member 410 is provided with a first transmission groove 431, and the protrusion 432 extends partially or completely into the first transmission groove 431.

[0078] See Figure 2 , Figure 3 as well as Figure 10 As shown, this application achieves snap-fit ​​transmission by having a protrusion 432 on the bottom surface of the drive member 410 pass through the first transmission groove 431 on the upper surface of the transmission member 420.

[0079] For example, the number of the first transmission groove 431 and the protrusion 432 can be designed according to actual needs. For instance, when the shape of the protrusion 432 and the first transmission groove 431 is polygonal, such as a triangle, quadrilateral, or pentagon, the number of the first transmission groove 431 and the protrusion 432 can be only one or more. Specifically, when there is only one first transmission groove 431 and protrusion 432, the protrusion 432 can be set at the center of the driving member 410, and the first transmission groove 431 can be set at the center of the transmission member 420. In this embodiment, the number of the first transmission groove 431 and the protrusion 432 can be one, two, three, or other numbers.

[0080] The transmission component 420 is provided with a positioning structure 600, which includes a receiving hole 610 formed on the circumferential surface of the transmission component 420. An elastic element 620 is provided in the receiving hole 610, and a connecting shaft 630 is also provided inside the receiving hole 610. A positioning element 640 is fixedly provided at the end of the connecting shaft 630 away from the center of the transmission component 420. The positioning structure 600 also includes a limiting groove 650 provided on the inner wall of the receiving cavity.

[0081] See Figure 2 , Figure 9 , Figure 10 as well as Figure 11 As shown, in order to determine whether the switching hole 210 and the water outlet hole 310 coincide during the rotation, the positioning structure 600 needs to position the transmission component 420, thereby achieving the positioning of the switching component 200. In this embodiment, there are multiple limiting grooves 650, and the limiting grooves 650 are formed on the inner wall of the base 110.

[0082] For example, the elastic element 620 is a compression spring.

[0083] Specifically, a receiving hole 610 is formed on the outer peripheral surface of the driven member 421, and an elastic member 620 is placed in the receiving hole 610. Then, the connecting shaft 630 is sleeved in the elastic member 620. At this time, one end of the elastic member 620 abuts against the inner wall of the end of the receiving hole 610, and the other end of the elastic member 620 abuts against the outer wall of the positioning member 640. In the initial state, the positioning member 640 is engaged in one of the connecting shafts 630 to achieve position positioning. When the rotation drive member 410 is rotated, the transmission member 420 transmits the rotational force through the transmission member 420. When the switching component 200 is rotated, the driving component 410 rotates to overcome the elastic force of the elastic component 620, causing the positioning component 640 to disengage from the limiting groove 650. Specifically, the positioning component 640 is subjected to a squeezing force, causing the elastic component 620 to contract until the positioning component 640 disengages from the limiting groove 650. As the rotation continues, when the switching hole 210 coincides with one of the water outlet holes 310, the positioning component 640 re-enters the limiting groove 650 at the corresponding position under the elastic force of the elastic component 620, thus achieving position positioning.

[0084] This application also provides a water distribution valve, including any of the valve cores described above. It can be understood that the water distribution valve includes all the technical effects of the valve cores described above.
