Description

Technical Field

[0001] This application relates to the field of household goods technology, and in particular to a water dispenser switch structure and a water dispenser. Background Technology

[0002] Water dispensers are an indispensable household appliance in people's daily lives. Currently, some water dispensers use a lever-type water outlet switch. The water outlet switch consists of a housing, valve stem, handle, and outlet bolt. The valve stem is equipped with a silicone sleeve, and a return spring is installed inside the silicone sleeve. The return spring abuts the end of the valve stem against the outlet of the housing to achieve a seal. Pulling the handle moves the valve stem upward to open the water outlet.

[0003] However, as people pay more attention to the quality of drinking water, water dispensers are often used in conjunction with ultrafiltration devices. This not only filters the water entering the dispenser but also increases the water pressure. After long-term use, the silicone sleeve is prone to coming off the valve stem due to the water pressure, resulting in poor sealing and easy leakage. Utility Model Content

[0029] Reference Figures 1 to 3 This application provides a water dispenser switch structure, including a housing 100 and a valve core. The housing 100 is provided with a chamber 110, which is provided with an inlet 120 and an outlet 130. The inlet 120 is located at the upper part of the chamber 110, and the outlet 130 is located at the bottom of the chamber 110. A rubber ring 140 adapted to the outlet 130 is provided at the bottom of the chamber 110. An opening is provided at the top of the chamber 110, and a sealing cover 150 is provided at the opening. The valve core includes a valve stem 210 and a metal plate 220. The valve stem 210 slides through a sealing member 160 and extends into the chamber 110. The metal plate 220 is welded to the bottom end of the valve stem 210. The metal plate 220 cooperates with the rubber ring 140 to close or open the outlet 130.

[0030] By providing a rubber ring 140 at the bottom of the chamber 110 that matches the outlet 130, and welding a metal sheet 220 to the bottom of the valve stem 210, the problem of leakage caused by the silicone sleeve coming off the valve stem 210 in related technologies is solved, ensuring the sealing effect of the outlet 130, extending its service life, and improving stability and reliability.

[0031] The material of the rubber ring 140 can be silicone, rubber or polyurethane, etc. Since it is used in scenarios with food-grade requirements such as water dispensers, the rubber ring 140 is preferably made of silicone.

[0032] In this embodiment, the metal sheet 220 includes a water-sealing part 230 and a positioning part 240. The positioning part 240 is circumferentially disposed at the edge of the water-sealing part 230, and a rubber ring 140 is disposed at the protrusion. The positioning part 240 cooperates with the protrusion to close or open the water outlet 130. There is a gap between the edge of the positioning part 240 and the inner wall of the chamber 110. A groove is provided between the edge of the rubber ring 140 and the protrusion. When the valve stem 210 slides, the metal sheet 220 moves up and down within the chamber 110 along with the valve stem 210, allowing the positioning part 240 to guide the valve stem 210 in linear motion, thus improving the performance.

[0033] Reference Figures 1 to 3 In some embodiments of this application, the sealing cover 150 includes a sealing element 160 and a fixing element 170. The sealing element 160 is inserted into the cavity 110 through the opening, and the outer wall of the sealing element 160 abuts against the inner wall of the cavity 110. The fixing element 170 abuts against the top of the sealing element 160. The sealing element 160 is threadedly connected to the housing 100, so that the fixing element 170 can achieve axial and radial sealing when it is closed on the housing 100. The sealing element 160 is made of an elastic material, such as silicone, rubber, or polyurethane. Since it is used in scenarios with food-grade requirements, such as water dispensers, the sealing element 160 is preferably made of silicone. It is conceivable that the outer wall surface of the sealing element 160 has a certain taper, which helps the sealing element 160 to be nested within the housing 100 and to achieve positional alignment.

[0034] Furthermore, the valve core also includes a spring 250, which is sleeved on the valve stem 210. The two ends of the spring 250 abut against the seal 160 and the metal plate 220, respectively. By providing the spring 250, the seal 160 can be pressed towards the fixing member 170, thereby ensuring good axial sealing of the housing 100 and improving stability and reliability.

[0035] It is easy to understand that the sealing cap 150 also includes a gasket 260, which is disposed between the seal 160 and the spring 250. The gasket 260 separates the seal 160 and the spring 250, thereby preventing direct interaction between the spring 250 and the seal 160 from damaging the seal 160, thus ensuring good sealing performance over a long period. Specifically, the gasket 260 has a concave pressing portion 270 facing the spring 250. The pressing portion 270 has a conical structure, and the bottom of the seal 160 has a protrusion 180 that matches the pressing portion 270. The pressing portion 270 presses against the protrusion 180, causing the protrusion 180 to squeeze the outer wall of the valve stem 210, thereby achieving a seal at the valve stem 210 and improving the sealing effect.

[0036] It is conceivable that the top of the valve stem 210 is provided with a through hole, and the through hole is connected to a handle 290 through a shaft 280, allowing the handle 290 to swing on the valve stem 210. Specifically, moving the handle 290 causes the shaft 280 to lift the valve stem 210, thereby causing the metal plate 220 to separate from the rubber ring 140 to allow water to flow out; when it is necessary to turn off the water, moving the handle 290 back causes the valve stem 210 to automatically return to its original position under the action of the spring 250. At this time, the metal plate 220 and the rubber ring 140 cooperate to close the water outlet 130, thereby turning off the water.

[0037] A second aspect of this application provides a water dispenser, including the water dispenser switch structure described in the first aspect of this application.

[0038] Applying the water dispenser switch structure described in the first aspect of this application to a water dispenser can solve the problem of leakage caused by the silicone sleeve coming off the valve stem 210 in the related art, ensure the sealing effect of the water outlet 130, extend the service life, and improve stability and reliability.

[0039] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
