[0001] This utility model belongs to the field of household appliance technology, and in particular relates to a coupler water supply mechanism. Background Technology

[0002] In daily life, small household appliances such as electric kettles and health pots are widely used by consumers due to their quick and convenient boiling of water. Automatic water-filling appliances are even more popular due to their unique water dispensing method. The water filling device, a conduit passing through the middle of the appliance coupler, is a crucial component for guiding liquid flow into the kettle. Chinese utility model patent CN222466674U discloses a coupler water filling mechanism, including an upper connector, an outlet pipe mounted on the upper connector seat, and an inlet pipe mounted on the lower connector seat. A sealing sleeve is provided between the inlet and outlet pipes. The sealing sleeve, through the cooperation of a spring and a sealing element, has both a sealed and an open state. However, the inlet pipe in this structure is prone to leakage when inserted or removed from the sealing sleeve, resulting in poor sealing performance. Utility Model Content

[0003] The purpose of this utility model is to provide a coupler water supply mechanism to address the aforementioned technical problems, thereby solving the issues raised in the background art.

[0004] In view of this, the present invention provides a coupler water supply mechanism, including an upper connecting seat and a lower connecting seat, wherein a water inlet pipe is installed on the lower connecting seat and a water outlet pipe that cooperates with the water inlet pipe is installed on the upper connecting seat;

[0005] A sealing assembly, comprising a hollow sealing sleeve installed at the lower port of the outlet pipe and a sealing element installed inside the outlet pipe and sealingly fitted with the sealing sleeve;

[0006] Leak-proof component: A leak-proof component is provided between the sealing sleeve and the sealing element.

[0007] In the above technical solution, the leak-proof component further includes:

[0008] An opening groove is formed on the inner wall of the sealing sleeve at one end near the lower connecting seat;

[0009] A sealing ring is fixedly connected to the end of the open groove;

[0010] A reducer is fixedly connected to the top of the inlet pipe. The opening groove is used for inserting the reducer, and the side wall of the reducer matches the sealing ring.

[0011] In the above technical solution, the lower surface of the seal is a spherical arc surface, the top of the seal is provided with an installation groove, a spring is provided in the water outlet pipe, one end of the spring is fixedly connected to the seal, and the other end is fixedly set in the installation groove.

[0012] In the above technical solution, further, the bottom of the seal is integrally formed with a protrusion, and the protrusion extends to the hollow part of the sealing sleeve.

[0013] In the above technical solution, the sealing sleeve further includes:

[0014] The exterior wall is sealed to the inner wall of the water outlet pipe.

[0015] The inner ring wall extends upward from the bottom of the outer wall, and an opening slot is provided at the bottom of the inner ring wall.

[0016] A gap is provided between the outer wall of the inner ring wall and the inner wall of the outer ring wall;

[0017] Under the action of the spring, the seal has a sealed state and an open state. In the sealed state, the seal forms a sealed barrier with the upper part of the inner ring wall through the spring. In the open state, the seal separates from the upper part of the inner ring wall to form a water outlet gap.

[0018] In the above technical solution, further, the upper part of the inner ring wall is a bowl-shaped lifting ring, and the upper free inner surface of the lifting ring is a spherical arc surface that matches the lower surface of the seal.

[0022] Furthermore, in the above technical solution, the outer wall of the water inlet pipe is provided with a lug.

[0023] The beneficial effects of this utility model are as follows:

[0024] 1. A leak-proof component is provided between the sealing sleeve and the sealing element to prevent water leakage when the upper connector is inserted and removed from the lower connector.

[0025] 2. During the coupling process of the upper and lower connecting seats, the water inlet pipe is first sealed and connected with the sealing sleeve, and then the protrusion is pushed open. The protrusion drives the sealing element to move upward, and the sealing element separates from the sealing sleeve, effectively opening the water injection channel. During the separation process of the upper and lower connecting seats, the combined force of the spring enables the sealing element to form a sealing barrier with the sealing sleeve to seal the water. After that, the water inlet pipe is separated, with no residual water. The design of the protrusion does not need to consider the water pressure, has low requirements for the water pump, and has a wide range of applications.

[0026] 3. The lifting ring is set higher than the outer wall, which helps to increase the area of ​​the lifting ring, i.e. the mating area with the seal, effectively ensuring the sealing performance and preventing the seal from falling excessively. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0037] Example 1:

[0038] This embodiment provides a coupler water supply mechanism, including an upper connecting seat 1 and a lower connecting seat 2. A water inlet pipe 3 is installed on the lower connecting seat 2, and a water outlet pipe 4 that cooperates with the water inlet pipe 3 is installed on the upper connecting seat 1.

[0039] The sealing assembly includes a hollow sealing sleeve 5 installed at the lower port of the water outlet pipe 4 and a sealing element 6 installed inside the water outlet pipe 4 and sealingly fitted with the sealing sleeve 5.

[0040] A leak-proof component is provided between the sealing sleeve 5 and the sealing element 6.

[0041] As can be seen in this embodiment, a water inlet pipe 3 is installed on the lower connecting seat 2, and a water outlet pipe 4 is installed on the upper connecting seat 1. The water inlet pipe 3 and the water outlet pipe 4 are compatible. The sealing assembly includes a hollow sealing sleeve 5 installed at the lower end of the water outlet pipe 4 and a sealing element 6 installed inside the water outlet pipe 4 and sealingly fitted with the sealing sleeve 5. The sealing sleeve 5 can be made of elastic materials such as rubber. A leak-proof component is provided between the sealing sleeve 5 and the sealing element 6 to prevent water leakage when the upper connecting seat 1 is inserted and removed from the lower connecting seat 2.

[0042] Example 2:

[0043] This embodiment provides a coupler water supply mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0044] Leak-proof components include:

[0045] Opening groove 19 is formed on the inner wall of the sealing sleeve 5 near the lower connecting seat 2;

[0046] A sealing ring 20 is fixedly connected to the end of the opening groove 19;

[0047] The reducer 21 is fixedly connected to the top of the water inlet pipe 3. The opening groove 19 is used for the insertion of the reducer 21. The side wall of the reducer 21 cooperates with the sealing ring 20.

[0048] As can be seen in this embodiment, a frustum-shaped opening groove 19 is provided on the inner wall of the sealing sleeve 5 near the lower connecting seat 2. A sealing ring 20 is fixedly connected to the end of the opening groove 19. The sealing ring 20 can be made of elastic material such as rubber. The sealing sleeve 5 and the sealing ring 20 are integrally formed. A reducer 21 is fixedly connected to the top of the water inlet pipe 3. The water inlet pipe 3 and the reducer 21 are internally connected. The opening groove 19 is used for the reducer 21 to be inserted. The side wall of the reducer 21 cooperates with the sealing ring 20. The water outlet end of the reducer 21 is inserted into the inner wall of the sealing sleeve 5 to achieve the effect of sealing and preventing water leakage. At this time, the outer wall of the reducing end of the reducer 21 abuts against the sealing ring 20 to achieve the effect of double sealing and preventing water leakage.

[0049] Example 3:

[0050] This embodiment provides a coupler water supply mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0051] The lower surface of the seal 6 is a spherical arc surface, and the top of the seal 6 is provided with an installation groove 7. A spring 8 is provided inside the water outlet pipe 4, and one end of the spring 8 is fixedly connected to the seal 6, while the other end is fixedly installed in the installation groove 7.

[0052] As can be seen from this embodiment, the lower surface of the seal 6 is a spherical arc surface. This shape helps to better match with the sealing sleeve 5 and improve the sealing effect. The sealing sleeve 5 cooperates with the seal 6 through the spring 8 and has a sealed state and an open state. In the open state, water can enter. In the closed state, the sealing effect is excellent.

[0053] Example 4:

[0054] This embodiment provides a coupler water supply mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0055] The bottom of the seal 6 is integrally formed with a protrusion 15, and the protrusion 15 extends to the hollow part of the sealing sleeve 5.

[0056] As can be seen from this embodiment, the bottom of the sealing element 6 is integrally formed with a protrusion 15. The integrally formed structure has high strength and long service life. The protrusion 15 extends to the hollow part of the sealing sleeve 5. During the coupling process of the upper connecting seat 1 and the lower connecting seat 2, the water inlet pipe 3 first seals and connects with the sealing sleeve 5, and then pushes open the protrusion 15. The protrusion 15 drives the sealing element 6 to move upward, and the sealing element 6 separates from the sealing sleeve 5, effectively opening the water injection channel. During the process of the upper connecting seat 1 and the lower connecting seat 2 separating, that is, the water inlet pipe 3 moves downward in the hollow part of the sealing sleeve 5, at this time, the combined force of the spring 8 enables the sealing element 6 to form a sealing barrier with the sealing sleeve 5 to seal the water. Then the water inlet pipe 3 separates. Compared with the water supply mechanism of the coupler that uses water pressure to push open the steel ball, water is easy to accumulate between the steel ball and the sealing sleeve, which has adsorption properties and affects the water supply efficiency. This structure has no residual water retention. The design of the protrusion 15 does not need to consider the water pressure, has low requirements for the water pump, and has a wide range of applications.

[0057] like Figure 4 As shown, in the longitudinal water outlet coupling water supply mechanism, four reinforcing ribs are fixedly installed on the upper side wall of the seal 6, and several limiting strips for limiting the reinforcing ribs are fixedly installed on the inner wall of the water outlet pipe 4.

[0058] like Figure 8 As shown, in the water supply mechanism of the coupler with horizontal water outlet, three reinforcing ribs are fixedly provided on the upper side wall of the seal 6, and the diameter of the seal 6 gradually decreases from bottom to top. Compared with the water supply mechanism of the coupler with vertical water outlet, it can increase the water flow of the horizontal water outlet.

[0059] Example 5:

[0060] This embodiment provides a coupler water supply mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0061] Sealing sleeve 5 includes:

[0062] The outer wall 9 is sealed to the inner wall of the water outlet pipe 4;

[0063] An inner ring wall 10 is formed inside the outer wall 9, extending upward from the bottom of the outer wall 9. An opening groove 19 is provided at the lower part of the inner ring wall 10.

[0064] A gap 11 is provided between the outer wall of the inner ring wall 10 and the inner wall of the outer wall 9;

[0065] Under the action of spring 8, the sealing element 6 has a sealed state and an open state. In the sealed state, the sealing element 6 forms a sealed partition with the upper part of the inner ring wall 10 through spring 8. In the open state, the sealing element 6 separates from the upper part of the inner ring wall 10 to form a water outlet gap.

[0066] As can be seen in this embodiment, the opening groove 19 is opened on one side of the inner ring wall 10, and the sealing ring 20 is integrally formed with the inner ring wall 10. Since the outer wall 9 and the inner ring wall 10 are designed with a gap 11, the insertion resistance of the reducer 21 is small and smoother, resulting in an outstanding and reliable sealing effect. Furthermore, the sealing sleeve 5 made of elastic materials such as rubber has high processing precision, simple structure, no need for secondary processing and demolding, convenient processing, and cost savings. At the same time, it improves the insertion stability of the water inlet pipe 3 and the smoothness of the fit between the upper connecting seat 1 and the lower connecting seat 2, avoiding jamming.

[0067] Example 6:

[0068] This embodiment provides a coupler water supply mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0069] The upper part of the inner ring wall 10 is a bowl-shaped lifting ring 12, and the upper free inner surface of the lifting ring 12 is a spherical arc surface that matches the lower surface of the seal 6.

[0070] As can be seen from this embodiment, the spherical arc surface design of the lifting ring 12 can make the sealing more stable and can be achieved without secondary processing, making the processing simple.

[0071] Example 7:

[0072] This embodiment provides a coupler water supply mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0073] The lifting ring 12 is partially or entirely higher than the outer wall 9.

[0074] As can be seen from this embodiment, the lifting ring 12 is set higher than the outer wall 9, which helps to increase the area of ​​the lifting ring 12, that is, the mating area with the sealing element 6, effectively ensuring the sealing performance and preventing the sealing element 6 from falling excessively.

[0075] Example 8:

[0076] This embodiment provides a coupler water supply mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0077] The outer perimeter of the outer wall 9 is also provided with an upturned ring wall 13 that rises outward from the bottom of the outer wall 9, and the lower end of the water outlet pipe 4 has a limiting step 14 that is compatible with the upturned ring wall 13.

[0078] As can be seen from this embodiment, by setting the upturned annular wall 13 and the limiting step 14, the sealing sleeve 5 can be accurately limited, which facilitates assembly and effectively improves the compatibility with the water outlet pipe 4.

[0079] Example 9:

[0080] This embodiment provides a coupler water supply mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0081] The top of the water outlet pipe 4 is provided with an outlet 16, and a limit ring 17 is detachably connected to the outlet 16. The top of the spring 8 is fixedly connected to the limit ring 17.

[0082] As can be seen from this embodiment, when the seal 6 or spring 8 is damaged and cannot work properly, the limiting ring 17 installed on the outlet 16 can be removed to replace the seal 6 or spring 8 inside the outlet pipe 4, thereby replacing part of the parts and avoiding replacing the entire upper connecting seat 1, saving costs and making the operation simple.

[0083] Example 10:

[0084] This embodiment provides a coupler water supply mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0085] The outer wall of the water inlet pipe 3 is provided with a lug 18.

[0086] As can be seen from this embodiment, the lug 18 provided on the outer wall of the water inlet pipe 3 limits the water inlet pipe 3 to the lower connecting seat 2.
