[0029] Embodiment 1:

[0030] like Figures 1 to 7 As shown, a pumping electric kettle includes a base 1 and a kettle 2, wherein the base 1 is provided with a lower coupler 3, and the kettle 2 is provided with an upper coupler 4, and the upper coupler 4 and the lower coupler 3 are provided with a circuit part and a water channel part, and after the upper coupler 4 is coupled with the lower coupler 3, the water channel parts and the circuit parts of the two couplers are connected, and a pump body 5 is provided in the base 1, and a water outlet column 6 is provided on one side of the base 1, and a water outlet pipe 61 is provided in the water outlet column 6, and the pump body 5 is used to pump the kettle 2 The inner water is pumped out and outputted through the water outlet pipe 61. The kettle 2 includes a kettle body 21 and a kettle cover 22. The kettle body 21 is provided with a handle 23, and the kettle 2 is provided with a pouring spout 24. This electric kettle provides users with dual usage methods. First, users can place a water receiving container under the water outlet column to utilize its pumping function to take water; secondly, users can also choose to hold the kettle to pour out water through the pouring spout. The dual-mode design greatly improves the applicability and convenience of the kettle, enabling it to meet the needs of most usage occasions.

[0031] Furthermore, a control main board 7 is arranged in the base 1, and the pump body 5 and the lower coupler 3 are connected to the control main board. At the same time, a control panel connected to the control main board 7 is arranged on the top of the water outlet column 6, and the control panel 8 can use physical buttons or touch buttons to control the electric kettle.

[0032] There can be multiple directions for pumping water from the kettle 2. In the present embodiment, a lower pumping structure is provided. Specifically, the upper coupler 4 comprises an upper pipe 41, a sealing ball 42, a sealing member 43 and a first elastic member 44. The upper pipe 41 is connected to the kettle body 21. The sealing member 43 is arranged at the lower end of the upper pipe 41. The sealing member 43 is axially penetrated with a channel 431. At least one sealing convex ring 432 is arranged in the channel 431. Under the action of the first elastic member 44, the sealing ball 42 abuts against the upper end of the sealing member 43 to form a seal, which is used to close the upper pipe 41 to prevent water from flowing out of the upper pipe 41. The lower coupler 3 It includes a lower pipe 31, one end of which is connected to the pump body 5, and the other end is coaxially arranged with the upper pipe 41. A protrusion 311 is arranged at the top of the lower pipe 31, and a water inlet 312 is arranged on the outer edge of the protrusion 311. When the upper coupler 4 is coupled with the lower coupler 3, the lower pipe 31 is inserted into the channel 431 to form a seal with the sealing convex ring 432 and the sealing ball 42 is separated from the sealing member 43, so that the water inlet 312 connects the upper pipe 41 and the lower pipe 31, thereby conducting the water path part of the upper coupler 4 and the lower coupler 3, allowing the pump body 5 to pump out the water in the kettle 2 along the path of the upper pipe 41, the water inlet 312 and the lower pipe 31.

[0033] Secondly, the width or length of the protrusion 311 is smaller than the corresponding size of the lower pipe 31, and the sealing ball 42 can be lifted up by the protrusion 311 so that a sufficient flow channel is formed between the sealing ball 42 and the sealing member 43 for water to pass through.

[0034] The seal 43 is made of a flexible material, and is provided with a first step portion 433 and a second step portion 434 on the outside. The outer diameter of the first step portion 433 is smaller than the outer diameter of the second step portion 434. The first step portion 433 and the second step portion 434 are both horizontally arranged sealing planes. The horizontally arranged sealing planes are abutted to form a seal, which ensures the precise positioning of the seal in the axial direction, thereby improving the sealing performance, especially when the upper coupler and the lower coupler are plugged in or the seal 43 is displaced in the axial direction under the impact of water flow. In addition, since the seal 43 is made of a flexible material, when the seal 43 is squeezed, its side wall can be deformed to a certain extent, and abut with the corresponding inner wall to form an additional sealing structure, further improving the sealing performance of the overall structure.

[0035] An upper mounting channel 401 for inserting the upper pipe 41 is provided in the middle of the upper coupler 4, a convex ring portion 402 is provided at the bottom end of the upper mounting channel 401, the second step portion 434 abuts between the upper pipe 41 and the convex ring portion 402, and a first sealing boss 403 parallel to the first step portion 433 is provided on the inner wall of the upper pipe 41, the first step portion 433 abuts against the first sealing boss 403 to ensure that the seal 43 does not undergo axial displacement and constitute a double sealing structure to prevent water leakage of the upper pipe 41.

[0036] A lower mounting channel 301 is provided in the middle of the lower coupler 3, and the lower pipe 31 is slidably arranged in the lower mounting channel 301, and a flange portion 302 is provided on the lower pipe 31. The lower mounting channel 301 is provided with a tapered portion 303 which is wider at the top and narrower at the bottom, and a second elastic member 304 is abutted between the flange portion 302 and the tapered portion 303. The second elastic member 304 can reduce the impact force generated on the lower coupler 3 when the kettle 2 is placed on the base 1, reduce damage to the coupler and its internal components, and improve the durability of the product.

[0037] The upper end of the upper pipe 41 is provided with an abutment plate 404, and the abutment plate 404 is provided with a through hole 405. There may be multiple through holes 405 for connecting the upper pipe 41 with the kettle 2. A push seat 406 is provided between the first elastic member 44 and the sealing ball 42. The first elastic member 44 adopts a tower-shaped compression spring. The push seat 406 and the tower-shaped compression spring ensure that the thrust from the spring to the sealing ball 42 is stable and uniform, reducing the lateral force, thereby protecting the sealing ball 42. Since the sealing ball 42 is generally a steel ball, the push seat 406 prevents the first elastic member 44 from directly contacting the sealing ball 42, thereby reducing damage to the sealing ball 42. The lower end of the first elastic member 44 is plugged into the push seat 406, and the push seat 406 is provided with an arc-shaped recess 407 adapted to the sealing ball 42 toward the sealing ball 42, ensuring that the sealing ball 42 is pushed to move along the axial direction of the first elastic member 44, thereby improving the sealing effect of the sealing ball 42 and the sealing member 43.

[0038] A gap 408 is provided between the outer wall of the first step portion 433 and the corresponding inner wall of the upper pipe 41 , so as to facilitate the assembly of the seal 43 and provide a space for the seal 43 to deform.

[0039] The channel 431 includes a first port 435 and a second port 436. The first port 435 is provided with an arc-shaped guide portion 437 toward the channel 431 to facilitate smooth insertion of the lower pipe 31 and improve the smoothness of the connection between the upper coupler and the lower coupler.

[0040] An arc-shaped sealing portion 438 is provided on the inner wall of the channel 431 close to the second port 436, and the arc-shaped sealing portion 438 is wide at the top and narrow at the bottom. The arc-shaped sealing portion 438 is matched with the sealing ball 42 in the upper coupler to form an effective seal. Compared with the conical design in the prior art, the arc-shaped sealing portion 438 has a better fit with the sealing ball 42, so the sealing performance is better.

[0041] The cross section of the sealing convex ring 432 is triangular, and the angular position is in a circular arc transition. Compared with the semicircular shape in the prior art, the sealing convex ring 432 with a triangular cross section generates less resistance when the lower pipe 31 is inserted. Especially when multiple sealing convex rings 432 are provided, the sealing performance can be ensured without affecting the insertion of the lower pipe 31, and the sealing convex rings 432 can be tilted toward the second port 436 and form a seal with the lower pipe 31, effectively preventing water on the upper side of this sealing position from flowing to the lower side.

[0042] A sealing clamp 439 is provided in the middle of the channel 431. The inner diameter of the sealing clamp 439 is smaller than the inner diameter of the sealing convex ring 432, which adds a sealing structure with a stronger sealing effect and plays a role in positioning the lower pipe 31, ensuring that the lower pipe 31 is axially aligned with the upper pipe 41, and the axial length of the sealing clamp 439 along the channel 431 is not less than 0.5 mm, ensuring the formation of an effective seal.

[0043] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
