Detailed implementation manners

[0026] To make the objectives, technical solutions, and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] It should be noted that all expressions using "first" and "second" in the embodiments of the present utility model are used to distinguish two entities or parameters with the same name but different identities. It can be seen that "first" and "second" are only for the convenience of expression and should not be construed as a limitation on the embodiments of the present utility model. This will not be elaborated one by one in subsequent embodiments.

[0028] The terms of direction and position mentioned in the present utility model, such as "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "top", "bottom", "side", etc., are only with reference to the direction or position of the accompanying drawings. Therefore, the terms of direction and position used are for explaining and understanding the present utility model, rather than a limitation on the protection scope of the present utility model.

[0029] As Figures 1 to 10 shown, an embodiment of the present utility model is an inlet and outlet electric water kettle, which includes a kettle body 1 and a base. The kettle body 1 is inserted and cooperated with the base through a thermostat 2 to form an electrical connection. The thermostat 2 is provided with a water injection pipe 3 communicating with the inner cavity of the kettle body 1. The water injection pipe 3 is also communicated with a water inlet assembly located in the base. The water inlet assembly includes a two-way pump 4 and a three-way pipe 5. One end of the two-way pump 4 is communicated with the water injection pipe 3 and the other end is communicated with the three-way pipe 5. The three-way pipe 5 is also respectively communicated with a water inlet pipe 6 and a water outlet pipe 7. A first check member 8 for communicating or blocking is provided between the water inlet pipe 6 and the three-way pipe 5, and a second check member 9 for communicating or blocking is provided between the water outlet pipe 7 and the three-way pipe 5. When the first check member 8 is in a communicating state, the second check member 9 is in a blocking state, and when the second check member 9 is in a communicating state, the first check member 8 is in a blocking state.

[0030] The beneficial effects of such a setting are as follows. The present utility model has a water outlet structure, that is, the thermostat at the bottom of the kettle body is connected to a two-way pump through a water injection pipe. The two-way pump is also connected to a three-way pipe, and the three-way pipe is connected to the water inlet pipe and the water outlet pipe at the same time. The two-way pump can switch the direction of suction and drainage. The two-way pump sucks water through the water inlet pipe. After heating, the two-way pump switches the state and drains water through the water outlet pipe. And check members for preventing backflow are installed on both the water inlet pipe and the water outlet pipe. When sucking water through the water inlet pipe, the water outlet pipe is closed, and vice versa, when the water outlet pipe discharges water, the water inlet pipe is closed. Therefore, it is not necessary to lift the kettle to drain water after the water is heated, making it more convenient, easier, and safer to use.

[0031] Further setting: The first check member 8 and the second check member 9 have the same structure. The second check member 9 includes a first valve body 10, a second valve body 11, a valve core 12, and a first spring 13. The first valve body 10 and the second valve body 11 are threadedly connected to each other and form a valve cavity inside for installing the valve core 12 and the first spring 13. The first spring 13 presses the valve core 12 towards the first valve body 10. When the second check member 9 is in the blocking state, the valve core 12 is in sealing fit with the first valve body 10.

[0032] The beneficial effects of such a setting are as follows: The internal component structures of the first check member and the second check member both have the advantages of being delicate and simple, having good sealing performance, fast switching speed, and strong check ability.

[0033] Further setting: The first valve body 10 is inserted and connected to the three-way pipe 5. A first annular groove 14 is recessed on the inner wall of the first valve body 10, and a snap ring 15 that is in snap-fit connection with the first annular groove 14 protrudes from the inner wall of the three-way pipe 5.

[0034] The beneficial effects of such a setting are as follows: The first valve body forms an inserted connection with the three-way pipe through the snap-fit connection between the snap ring and the first annular groove, with better sealing performance and higher connection strength.

[0035] Further setting: A second annular groove 16 that can also be in snap-fit connection with the snap ring 15 is further recessed on the inner wall of the first valve body 10. An arc convex ring 17 is connected between the first annular groove 14 and the second annular groove 16, and the depth of the second annular groove 16 is less than that of the first annular groove 14.

[0036] The beneficial effects of such a setting are as follows: The second annular groove with a depth smaller than that of the first annular groove on the first valve body is also used for snap-fit connection with the snap ring. Pull the first valve body away from the three-way pipe to make the snap ring slide into the second annular groove. The snap-fit connection between the second annular groove and the snap ring is more firm, further reducing the gap and having a better sealing effect. The arc convex ring is used for the snap ring to slide into the second annular groove and is not prone to slipping.

[0037] Further setting: The base includes a bottom plate 18 and a housing 19. A shock-absorbing block 20 for installing the two-way pump 4 is provided inside the housing 19. A notch 21 for the two-way pump 4 to extend into is opened in the middle of the shock-absorbing block 20. A connecting plate 22 is provided on the two-way pump 4, and a card slot 23 for the connecting plate 22 to extend into is further provided on the side of the shock-absorbing block 20.

[0038] The beneficial effects of such a setting are as follows: The shock-absorbing block is installed on the inner top of the housing. The shock-absorbing block is used for installing the two-way pump and surrounds the outer wall of the two-way pump, which can effectively reduce the vibration of the two-way pump and make the overall structure operate more stably. The card slot on the side of the shock-absorbing block allows the connecting plate of the two-way pump to extend into it, improving the connection strength between the two-way pump and the shock-absorbing block.

[0039] Further setting: Inside the card slot 23, there are balls 24 and a second spring 25. There is also a protrusion 26 in the card slot 23 for limiting the balls 24 within the card slot 23. The second spring 25 presses the balls 24 towards the outside of the card slot 23. When the connecting plate 22 is snap-connected to the card slot 23, the balls 24 abut against the side surface of the connecting plate 22. There is also a mounting block 27 protruding from the side of the shock-absorbing block 20. The connecting plate 22 is fixedly connected to the mounting block 27 through a bolt member.

[0040] The beneficial effects of such a setting are as follows: The connecting plate is fixedly connected to the mounting block through a bolt member. In this embodiment, the bolt member is a screw. When the screw is unscrewed, the connecting plate is limited within the card slot by the balls and the second spring, and the two-way pump will not directly separate from the shock-absorbing block, avoiding damage to the two-way pump, facilitating disassembly and assembly, and further improving the connection strength.

[0041] Further setting: The axis of the end of the tee pipe 5 connected to the water outlet pipe 7 forms an angle of 10° to 30° with the horizontal plane.

[0042] The beneficial effects of such a setting are as follows: In this embodiment, the angle is 10°. The inclination angle of 10° has the best drainage effect and can help the water remaining in the tee pipe to drain along the water outlet pipe.

[0043] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
