[0034] The utility model provides a water valve.

[0035] In the embodiment of the present utility model, please refer to Figures 1 to 3 , the water valve includes:

[0036] A water valve base 100, wherein the water valve base 100 is provided with a water outlet 110; and

[0037] The water outlet body 200 is arranged at the lower end of the water valve base 100. The water outlet body 200 is nested in the water valve base 100. The water outlet body 200 includes a valve core 220 and a hollow sealing portion 210. The upper peripheral edge of the sealing portion 210 is connected to the water valve base 100, and the upper part of the sealing portion 210 is connected to the water outlet 110, and the lower part is connected to the water outlet 234 of the water outlet body 200. The valve core 220 is penetrated by the sealing portion 210, and the lower end of the valve core 220 is connected to the sealing portion 210 through the pushing portion 230, and the upper end is provided with a blocking portion 222. The sealing portion 210, the pushing portion 230 and the water valve base 100 are integrally formed, and the sealing portion 210 is deformable;

[0038] The water outlet 200 can reciprocate axially relative to the water valve base 100. In the initial position of the valve core 220, the blocking portion 222 blocks the water outlet 110. In the operating position of the valve core 220, the water outlet 110 is opened.

[0039] The technical solution of the present utility model is to integrally form the sealing part 210, the pushing part 230 and the water valve base 100 to ensure the sealing of the connection between the sealing part 210 and the pushing part 230, and the connection between the sealing part 210 and the pushing part 230. In this way, when the user needs to take water, the pushing part 230 is firstly resisted and pushed to move upward, thereby pushing the valve core 220 to move upward, so that the valve core 220 is switched from the initial position to the action position, that is, the water outlet 110 is switched from being blocked by the blocking part 222 to being opened without being blocked, and water flows from the water valve base 100 through the water outlet 110 into the sealing part 210, and then flows out of the water valve from the water outlet 234 to achieve water taking. During this process, the sealing part 210 is deformed under the pushing action of the pushing part 230. The deformation direction of the sealing part 210 can be parallel to the reciprocating motion direction of the valve core 220 or at an angle to the reciprocating motion direction of the valve core 220, thereby ensuring that the deformation of the sealing part 210 will not affect the sealing of the connection between the sealing part 210 and the pushing part 230 or the water valve base 100. That is, in the process of water flowing from the water outlet 110 to the water outlet 234, the water is restricted to flow in the sealing part 210, thereby avoiding water valve leakage and ensuring the user experience.

[0040] Among them, the blocking part 222 can block the water outlet 110 on the side of the water valve base 100 away from the pushing part 230. In the initial position, the blocking part 222 covers the surface of the water outlet 110. In the operating position, the blocking part 222 protrudes from the water outlet 110 so that the water outlet 110 is exposed. The blocking part 222 can also be interference fit in the water outlet 110. In the initial position, the blocking part 222 is interference inserted in the water outlet 110. In the operating position, the blocking part 222 protrudes from the water outlet 110 so that the water outlet 110 is exposed. Without loss of generality, a water passage is provided at the upper end of the water valve base 100, the radial area of ​​the water passage is larger than the area of ​​the water outlet 110, and the valve core 220 and the sealing portion 222 can freely reciprocate in the axial direction, so that water from the external water tank can flow from the water passage to the water outlet 110, and when the sealing portion 222 is in the initial position, the water in the water passage cannot pass through the water outlet 110, and when the sealing portion 222 is in the operating position, the water in the water passage can only flow through the water outlet 110 to the sealing portion 210.

[0041] It should be noted that the upper and lower parts mentioned in this embodiment are all based on the use status of the water valve. Figure 4 and Figure 5 In addition, the deformation direction of the sealing part 210 is consistent with the deformation direction of the valve core 220 as much as possible to improve the durability of the water valve, and the sealing part 210 can be made of elastic material, or an elastic structure is embedded in the sealing part 210, and the elasticity of the sealing part 210 is used to cause the water outlet 200 to automatically switch back to the initial position, or a separate elastic member 300 is provided, and the elastic member 300 is sandwiched between the water valve base 100 and the pushing part 230, and the sealing part 210 only has the ability to deform but not elastic, and the elastic ability of the elastic member 300 is used to enable the water outlet to automatically switch back to the initial position.

[0042] In one embodiment, please refer to Figure 2 and Figure 5 , the sealing part 210 can be elastically deformed. Specifically, the material of the sealing part 210 can be configured as an elastic material, or an elastic body with elastic deformation ability can be embedded in the sealing part 210, so that the sealing part 210 has elastic deformation ability. Among them, the elastic deformation direction of the sealing part 210 is parallel to the reciprocating motion direction of the valve core 220, so as to avoid the sealing part 210 from shearing deformation and damage, resulting in water valve leakage, thereby improving the reliability and stability of the sealing part 210.

[0043] In one embodiment, please refer to Figure 2 and Figure 5The water valve further includes an elastic member 300, which is sleeved on the outer periphery of the sealing portion 210 and elastically clamped between the water valve base 100 and the pushing portion 230. It can be understood that in this embodiment, the sealing portion 210 may have only deformation capability, or may have both deformation capability and elastic capability. In the initial position, the elastic body is in an elastically compressed state so that the blocking portion 222 can tightly seal the water outlet 110. In the action position, the water valve base 100 and the pushing portion 230 are close to each other, and the elastic member 300 is still in an elastically compressed state. However, the elastic potential energy of the elastic member 300 at this time is greater than the elastic potential energy of the elastic member 300 in the initial position. After the user releases the pressing action, the elastic member 300 releases the elastic potential energy, and the water valve base 100 and the pushing portion 230 move away from each other, thereby switching the water outlet 200 from the action position back to the initial position, so that the blocking portion 222 re-blocks the water outlet 110. That is, the elastic expansion and contraction direction of the elastic member 300 is parallel to the distribution direction of the water valve base 100 and the pushing portion 230, and is also parallel to the reciprocating motion direction of the valve core 220. In this way, the elastic reset ability of the water outlet 200 can be changed by replacing the elastic part 300 to adapt to various drinking water equipment, or, after the elastic reset ability of the water valve is weakened, only the elastic part 300 needs to be replaced, thereby improving the adaptability of the water valve and reducing the maintenance cost of the water valve.

[0044] Without loss of generality, in this embodiment, please refer to Figure 2 and Figure 5 , the material of the sealing part 210 is configured as a silicone material. In particular, when applied to a water dispenser, the material of the sealing part 210 is a food-grade silicone material. Similarly, the elastic member 300 is configured as a compression spring. During the use of the water valve, the compression spring is always in an elastic compression state, wherein the two ends of the compression spring can be respectively limitedly connected to the water valve base 100 and the pushing part 230. Of course, in other embodiments, the material of the sealing part 210 can also be configured as a deformable food-grade plastic, and the elastic member 300 can also be configured as a spring that is elastically deformed in the axial direction.

[0045] Further, in this embodiment, please refer to Figure 2 , Figure 5 and Figure 6, the push part 230, the sealing part 210 and the water valve base 100 are integrally formed by insert injection molding or two-color injection molding. It can be understood that the material of the water valve base 100 and the push part 230 is configured as a plastic material. During the integral molding process of the water valve base 100, the push part 230 and the sealing part 210, the silicone and the plastic can be well connected into a whole, thereby effectively preventing the water valve from leaking due to gaps and cracks, and also improving the molding rate and production efficiency. Of course, in other embodiments, the material of the water valve base 100 and the push part 230 can also be a metal material, and the water outlet 200 and the water valve base 100 are integrally formed with the sealing part 210 by insert injection molding, or the water valve base 100, the push part 230 and the sealing part 210 are all made of plastic or metal materials, and the three are integrally formed by casting, wherein the sealing part 210 has the ability to deform.

[0046] In one embodiment, please refer to Figure 2 and Figure 3 The sealing part 210 has a plurality of folding parts 211 distributed along the axial direction, and the folding parts 211 form an angle with the axial direction of the sealing part 210, and two adjacent folding parts 211 are also arranged at an angle so that they can be folded with each other. It can be understood that the folding parts 211 are arranged in an annular structure, and in the axial direction of the sealing part 210, the cross-sectional area of ​​the folding parts 211 gradually increases or decreases. For example, in the direction from the driving part 230 to the water valve base 100, the cross-sectional area of ​​the folding part 211 gradually increases, and the cross-sectional area of ​​the next folding part 211 gradually decreases. In this way, when the water outlet body 200 switches between the initial position and the action position, the adjacent folding parts 211 can fold closer to and away from each other in the axial direction to guide the sealing part 210 to deform in the axial direction, adapt to the spatial changes between the pushing part 230 and the water valve base 100, and ensure that the deformation direction of the sealing part 210 is parallel to the reciprocating motion direction of the water outlet body 200, thereby avoiding gaps and water leakage at the connection between the sealing part 210 and the water valve base 100 and the pushing part 230. Specifically, some adjacent two folding parts 211 can be directly connected at an angle, or can be connected at intervals. Of course, in other embodiments, the sealing part 210 can also be configured to be in a shape similar to a hose, and its deformation direction is not guided.

[0047] Further, in this embodiment, please continue to refer to Figure 2 and Figure 3, the thickness of the connection between two adjacent folding parts 211 is less than the thickness of the folding parts 211. It can be understood that each folding part 211 is characterized by: in the axial direction of the sealing part 210, the thickness of the two ends of the folding part 211 is less than the thickness of the middle part. In this way, in the process of deformation of the sealing part 210, the part with a smaller thickness is first deformed by force, thereby limiting the position where the sealing part 210 is preferentially deformed to the connection of the folding parts 211, so as to improve the deformation smoothness of the sealing part 210, facilitate the switching of the water outlet 200 between the initial position and the action position, and improve the user's convenience. Of course, in other embodiments, the thickness of each part of the sealing part 210 can be set to be uniform.

[0048] In one embodiment, please refer to Figure 2 and Figure 3 The sealing portion 210 further includes connecting ends 212 disposed at both ends. The connecting ends 212 extend along the axial direction of the sealing portion 210 . The two connecting ends 212 are respectively connected to the water valve base 100 and the pushing portion 230 . It should be noted that the folding portion 211 and the connecting end 212 are connected at an angle. Compared with the angle between two adjacent folding portions 211, the angle between the connecting end 212 and the folding portion 211 is smaller, so that the degree of deformation between the connecting end 212 and the folding portion 211 is lower than the degree of deformation between the multiple folding portions 211. In this way, during the deformation of the sealing portion 210, the folding portions 211 are preferentially folded with each other and deformed, and the degree of deformation of the connecting end 212 is lower, so as to cause the deformation of the sealing portion 210 to be mainly concentrated in the middle position where the multiple folding portions 211 are located, thereby avoiding deformation of the connection between the sealing portion 210 and the water valve base 100 and the pushing portion 230, thereby avoiding gaps and water leakage at the connection between the sealing portion 210 and the water valve base 100 and the pushing portion 230. Of course, in other embodiments, the material of the connecting end 212 may be configured as a stronger material, and the material of the folding portion 211 may be configured as a softer material, so that the deformation of the sealing portion 210 is concentrated at the axial middle position thereof.

[0049] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 5The inner peripheral wall of the water valve base 100 is convexly provided with a connecting ring protrusion 120, the upper peripheral edge of the sealing part 210 is connected to the connecting ring protrusion 120, the upper end of the elastic member 300 abuts against the connecting ring protrusion 120, the pushing part 230 is connected to the lower end of the sealing part 210, and has an abutting ring protrusion 231 protruding from the outer periphery of the sealing part 210, and the lower end of the elastic member 300 abuts against the abutting ring protrusion 231. It can be understood that the cross-sectional area of ​​the elastic member 300 in the axial direction is equal, the connecting ring protrusion 120 and the abutting ring protrusion 231 are opposite in the axial direction of the sealing part 210, or the cross-sectional area of ​​the elastic member 300 in the axial direction changes gradually, the connecting ring protrusion 120 and the abutting ring protrusion 231 are distributed in the axial direction, and are offset and opposite in the radial direction. In this way, during the reciprocating motion of the water outlet body 200 , the relative motion between the abutting annular protrusion 231 and the connecting annular protrusion 120 can better guide the elastic member 300 to undergo elastic deformation, thereby improving the smoothness of the reciprocating motion of the water outlet body 200 and the ease of operation.

[0050] Without loss of generality, in this embodiment, please continue to refer to Figure 2 and Figure 5 The push part 230 is in the form of a cap structure, the abutting annular protrusion 231 is configured as a cap brim, the water outlet 234 is arranged at the top of the cap body of the push part 230, the periphery of the cap body of the push part 230 is connected to the lower periphery of the sealing part 210 at the periphery of its opening, and the side of the abutting annular protrusion 231 away from the sealing part 210 is configured as an action position pressed by the user, and the user realizes the switching of the water outlet 200 between the initial position and the action position by pushing this position. Among them, the cap body of the push part 230 is connected to the lower end of the valve core 220, and its connection structure can ensure the connection stability between the valve core 220 and the push part 230, and at the same time, it can also keep the water outlet 234 connected with the inside of the sealing part 210, so as to smoothly push the water outlet 200 to switch between the initial position and the action position, and also ensure the water intake reliability of the water valve. Specifically, the upper peripheral edge of the sealing portion 210 is connected to the inner peripheral edge of the connecting annular protrusion 120, and the water outlet 110 is formed in the inner ring of the connecting annular protrusion 120, wherein the connecting end 212 of the sealing portion 210 is connected to the connecting annular protrusion 120 in an axial direction in a manner close to vertical, so as to avoid deformation of the connection between the upper connecting end 212 and the connecting annular protrusion 120 and the lower connecting end 212 and the pushing portion 230 during the movement of the water outlet part as much as possible, thereby effectively avoiding water leakage at this location.

[0051] Further, in this embodiment, please refer to Figure 2 and Figure 6The pushing part 230 includes a limiting sleeve 232 disposed on the abutting annular protrusion 231. The limiting sleeve 232 is sleeved on the outer periphery of the sealing part 210 at intervals to enclose a limiting annular groove 233. The elastic member 300 is disposed in the limiting annular groove 233. In this way, in the process of pushing out the water body 200, the limiting annular groove 233 enclosed by the limiting sleeve 232 and the sealing part 210 forms a guiding effect of elastic deformation on the elastic member 300, so as to limit the deformation direction of the elastic member 300 and avoid the elastic failure caused by the misalignment of the elastic deformation direction and the movement direction of the water body 200. There is a certain movable gap between the limiting sleeve 232 and the connecting annular protrusion 120, and the movable gap meets the space requirement for the reciprocating motion of the water body 200.

[0052] In one embodiment, please refer to Figure 3 and Figure 6 , the upper end of the valve core 220 extends out of the sealing part 210, and the blocking part 222 covers the water outlet 110. It can be understood that the blocking part 222 is arranged above the water outlet 110 in a cap shape. In the initial position, the blocking part 222 covers the water outlet 110 to block the water outlet 110. In the action position, the upper end of the valve core 220 extends out of the upper end of the sealing part 210, pushing the blocking part 222 to open the water outlet 110 and make it above the water outlet 110. In this way, when the water outlet 200 switches between the initial position and the action position, the blocking part 222 can smoothly open and close the water outlet 110, ensuring the control reliability and stability of the water valve. Specifically, the valve core 220 includes a valve stem 221 and a sealing part 222, and the upper end of the valve stem 221 is detachably connected to the sealing part 222 by snap-fitting, wherein the sealing part 222 is made of silicone material, and the valve core 220 is made of plastic material, thereby improving the assembly and production convenience of the water outlet 200.

[0053] Further, in this embodiment, please refer to Figure 3 and Figure 6 , a guide portion 130 is provided at the upper end of the connecting annular protrusion 120 relative to the sealing portion 210, a guide hole 131 is opened in the guide portion 130, the valve core 220 can be movably penetrated in the guide hole 131, and the water outlet 110 is provided in the guide portion 130. It should be noted that the guide portion 130 is provided on the inner periphery of the connecting annular protrusion 120, and the strength of the guide portion 130 is greater than the strength of the sealing portion 210, and is equivalent to the strength of the connecting annular protrusion 120. In this way, during the movement of the water outlet 200, the guide portion 130 and the water valve base 100 remain stable, and the valve core 220 reciprocates in a directional manner under the limiting action of the guide hole 131, thereby ensuring the stability and reliability of the blocking portion 222 in opening and closing the water outlet 110.

[0054] The utility model also proposes a water dispenser, which includes a water valve. The specific structure of the water valve refers to the above embodiment. Since the water dispenser adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0055] The utility model also provides a refrigerator, which includes a water dispenser. The water dispenser includes the water valve in the above-mentioned embodiments.
