Description

Technical Field

[0001] This utility model relates to an electric kettle, and more particularly to a water supply device for a spring-flow type electric kettle. Background Technology

[0002] In daily life, electric kettles are essential household appliances in modern kitchens and living rooms due to their speed and convenience in boiling water, suitable for brewing tea, coffee, beverages, and more. Automatic kettles, with their unique water dispensing mechanism, are particularly popular. The thermostat is a crucial component of automatic kettles; however, current thermostats used in automatic kettles often have poor sealing between the inlet and outlet pipes, leading to leaks. While current thermostats commonly use steel balls to achieve a seal, this sealing mechanism suffers from issues like rolling misalignment and jamming. Furthermore, the complex sealing components can cause delays in the water dispensing process and the potential for residual water. Summary of the Invention

[0003] This utility model provides a water supply device for a fountain kettle that features good sealing performance, simplified structure, and rapid response.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a water supply device for a spring-flowing kettle, comprising a lower water inlet assembly installed in the central channel of the lower electrical connector and connected to a water pumping device, and an upper water inlet assembly installed in the central channel of the upper electrical connector, wherein the upper water inlet assembly comprises:

[0005] The water outlet inner pipe has a hollow cavity, and the inner wall of the middle section of the hollow cavity has a downward-contracting inclined annular surface.

[0006] The water guide is fixedly installed at the top of the hollow chamber in the inner water outlet pipe. The water guide has a central guide hole and an axial water inlet hole that communicates with the inner cavity of the kettle.

[0007] The hollow rubber sealing sleeve is fixed at the lower end of the water outlet inner pipe and receives the water outlet inner pipe and the lower water inlet pipe of the lower water inlet assembly, respectively.

[0008] The valve body is housed in a hollow cavity. The top of the valve body is limited to move up and down within the central guide hole. The lower part of the valve body has a sealing part that mates with the inclined ring surface for sealing.

[0009] A spring is fitted onto the valve body, with its two ends respectively abutting against the bottom of the water guide and the lower part of the valve body or the sealing part.

[0010] The outer diameter of the sealing part contracts from top to bottom, meaning the maximum outer diameter of the sealing part is greater than the minimum diameter of the inclined ring surface, and the minimum outer diameter of the sealing part is less than the minimum diameter of the inclined ring surface. This allows the valve body, along with the sealing part, to seal under the action of the spring when water filling stops. When water is filled, the liquid overcomes the spring force through the lower water inlet pipe of the lower water inlet assembly, and the valve body moves upward along the central guide hole. The seal between the sealing part and the inclined ring surface is released, and the liquid is injected into the inner cavity of the pot through the hollow cavity and the axial water inlet hole.

[0011] As an improvement: the rubber sealing sleeve includes an outer wall that seals with the inner wall of the outlet pipe, and an inner ring wall that extends upward from the bottom of the outer wall. The outer wall of the inner ring wall and the inner wall of the outer wall have a gap in the free state. The lower part of the inner ring wall forms a lower socket channel that is adapted to the lower water inlet pipe and allows the lower water inlet pipe to be inserted.

[0012] As an improvement: the lower end of the valve body is a spherical arc surface that can be sealed with a hollow rubber sealing sleeve. Under the action of the spring, the spherical arc surface and the hollow rubber sealing sleeve have a sealed state and an open state. In the sealed state, the spherical arc surface forms a sealed barrier with the upper part of the inner ring wall through the spring. In the open state, that is, when water is injected, the valve body moves upward and the spherical arc surface separates from the upper part of the inner ring wall to form a water outlet gap for liquid to pass through.

[0013] As an improvement, an upper inlet cover is also provided on the top of the inner outlet pipe, which is fixed by a sealing pressure ring.

[0014] As an improvement, the sealing part is a silicone body integrally molded on the lower part of the valve body.

[0015] The beneficial effects of this invention are as follows: The sealing part on the valve body cooperates with the inclined annular surface of the inner outlet pipe to achieve sealing. The guide valve body's movement is consistent with the liquid flow direction and its center is stable, ensuring sealing correspondence and effectively avoiding the problem of moving parts skewing or shifting. The upper inlet assembly integrates dynamic and static components, as well as hardware and software, improving response timeliness and sealing stability. Simultaneously, the upper inlet assembly has simplified components, is easy to assemble, has low cost, and is highly compatible with the lower inlet assembly, greatly reducing residual water retention and hygiene hazards.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0023] In the description of this utility model, it should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, it should be understood that the terms "connected," "joined," and "fixed," etc., used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or a welded connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction relationship between two components, unless otherwise explicitly defined. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the first embodiment of the water supply device for the spring-flowing kettle of this utility model includes a lower water inlet assembly installed in the central channel of the lower electrical connector and connected to the water pumping device, and an upper water inlet assembly installed in the central channel of the upper electrical connector. The upper water inlet assembly includes a water outlet inner pipe 1 with a hollow chamber, a water guide 2, a hollow rubber sealing sleeve 5, a valve body 3, a spring 4, and an upper water inlet cover 9 fixed on the top of the water outlet inner pipe 1 by a sealing pressure ring 8. The inner wall of the middle section of the hollow chamber has a downwardly contracting inclined annular surface 11. The water guide 2 is fixedly installed at the top position of the hollow chamber of the water outlet inner pipe 1, and the water guide 2 has a central guide hole 21 and an axial water inlet hole 22 communicating with the inner cavity of the kettle. The hollow rubber sealing sleeve 5 is fixed at the lower end of the water outlet inner pipe and receives the water outlet inner pipe 1 and the lower water inlet pipe of the lower water inlet assembly, respectively. The valve body 3 is housed within a hollow cavity. The top of the valve body is movable up and down within the central guide hole 21. The lower part of the valve body 3 has a sealing part 31 that mates with the inclined annular surface 11 for sealing. The sealing part is an integrally formed silicone body on the lower part of the valve body. A spring 4 is sleeved on the valve body 3, with its two ends abutting against the bottom of the water guide 2 and the lower part of the valve body or the sealing part 31, respectively. The outer diameter of the sealing part tapers from top to bottom, meaning that the maximum outer diameter of the sealing part is greater than the minimum diameter of the inclined annular surface 11, and the minimum outer diameter of the sealing part is less than the minimum diameter of the inclined annular surface 11. This allows the valve body, along with the sealing part, to seal with the inclined annular surface 11 under the action of the spring when water filling stops. When water is filled, the liquid overcomes the spring force through the lower water inlet pipe of the lower water inlet assembly, and the valve body 3 moves upward along the central guide hole 21. The seal between the sealing part and the inclined annular surface 11 is released, and the liquid is injected into the inner cavity of the kettle through the hollow cavity and the axial water inlet hole.

[0025] like Figure 5 , Figure 6As shown, in the second embodiment of the water supply device of this utility model, a second seal is added based on the first embodiment. Specifically, the lower end of the valve body 3 is a spherical arc surface 32 that can be sealed with a hollow rubber sealing sleeve. Under the action of the spring 4, the spherical arc surface 32 and the hollow rubber sealing sleeve have both a sealed state and an open state. In the sealed state, the spherical arc surface 32 forms a sealed barrier with the upper part of the inner ring wall 52 through the spring 4. In the open state, i.e., when water is injected, the valve body moves upward, and the spherical arc surface 32 disengages from the upper part of the inner ring wall 52, forming a water outlet gap for liquid to pass through. The rubber sealing sleeve includes an outer wall 51 that seals with the inner wall of the water outlet pipe 1, and an inner ring wall 52 extending upward from the bottom of the outer wall. The outer wall of the inner ring wall 52 and the inner wall of the outer wall 51 have a gap in the free state. The lower part of the inner ring wall 52 forms a lower socket channel adapted to the lower water inlet pipe (not shown in the figure) for insertion. The upper part of the inner ring wall 52 is a bowl-shaped supporting ring. The upper free inner surface of the supporting ring is a spherical arc shape that matches the surface of the spherical arc surface 32 at the lower end of the valve body. The supporting ring is partially or entirely set higher than the outer wall 51. The supporting part of the supporting ring can effectively ensure the sealing performance. The rubber sealing sleeve has high processing precision, simple structure, no need for secondary processing and demolding, convenient processing, and better sealing stability. In order to ensure that the sealing sleeve can be accurately limited and easy to assemble, and effectively improve the fit with the water outlet pipe, the outer periphery of the outer wall 51 is also provided with an upward-curving ring wall 54 that flips outward from the bottom of the outer wall 51. The lower end of the pipe wall of the inner water outlet pipe 1 has a limiting step that matches the upward-curving ring wall 54. Since the second seal and the first seal of the sealing part 31 are both driven by the valve body, the two are synchronized, react quickly, and there is no problem of residual water retention.

[0026] Although the present invention has been disclosed above with specific embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of the appended claims.
