[0022] In order to better understand the purpose, structure and function of the present invention, an electric kettle and its base of the present invention are further described in detail below with reference to the accompanying drawings.
[0023] like Figure 1 As shown, the base of the electric kettle of the present invention includes an upper cover 1 and a bottom shell 7. The upper cover 1 covers the opening at the top of the bottom shell 7. A coupler 2 is arranged at the center of the upper cover 1. A heating device is arranged in the base. One end of the heating device is electrically connected to the coupler 2 through a wire, and the other end of the heating device is electrically connected to a power source. A waterproof structure is arranged on the top of the coupler 2 to isolate water droplets from entering the coupler 2 and causing damage to the circuit elements in the base.
[0024] The coupler 2 comprises a bottom plate, on the top surface of which three annular support plates are coaxially arranged, and contacts 3 are symmetrically arranged on the support plate in the middle, and each pair of contacts 3 is respectively arranged on the inner and outer side walls of the support plate.
[0025] One of the contacts 3 is electrically connected to the heating device, and the other contact 3 is electrically connected to the wire. The heating device and the wire are respectively connected to the positive and negative electrodes of the power supply, thereby forming a heating circuit.
[0026] The waterproof structure is a waterproof sealing ring, which includes three sealing rings, namely a first sealing ring 4, a second sealing ring 5 and a third sealing ring 6. The three sealing rings are coaxially arranged and respectively sleeved on the top ends of the three annular support plates.
[0027] The cross section of the sealing ring is inverted L-shape. The sealing ring includes side walls and transverse walls. The top of the side wall is fixedly connected to the outer edge of the transverse wall. The side wall of the sealing ring is tightly sleeved on the outer wall of the support plate, and the transverse wall of the sealing ring abuts against the top surface of the support plate.
[0028] In order to ensure that the sealing ring has a good sealing effect, the width of the transverse wall is consistent with the width between adjacent support plates.
[0029] At the same time, in order to firmly fix the sealing ring on the support plate, an anti-slip structure is provided on the inner wall of the sealing ring in contact with the support plate.
[0030] The anti-skid structure may be an anti-skid protrusion arranged on the inner wall of the sealing ring, and the anti-skid protrusion may include a plurality of anti-skid protrusions evenly distributed on the inner wall of the sealing ring.
[0031] Alternatively, the anti-skid structure may also be an annular anti-skid rib, which may include a plurality of anti-skid ribs, and the plurality of anti-skid ribs may be evenly arranged on the inner wall of the sealing ring.
[0032] In addition, the sealing ring is fixed to the support plate by glue, so as to further enhance the connection strength between the sealing ring and the support plate.
[0033] After the kettle is removed, the sealing ring needs to be automatically reset. The sealing ring is made of elastic materials such as silicone, rubber, and resin.
[0034] The present invention also provides an electric kettle, comprising a kettle body and the above-mentioned base of the electric kettle, a thermal cut-off device matched with the coupler 2 is arranged on the bottom surface of the kettle body, and a copper ring is arranged on the thermal cut-off device. When the kettle body is placed on the base, the thermal cut-off device of the kettle body passes through the sealing ring and enters into the coupler 2, and the copper rings respectively contact with the relative contacts 3, so that the heating circuit is turned on, and the electric kettle is powered by the power supply. By arranging a sealing ring on the coupler 2 of the base, water droplets are effectively prevented from entering into the coupler 2, and a short circuit is avoided, thereby achieving a sealing effect and solving the problem of potential safety hazards caused by water ingress into the coupler 2 of the electric kettle.
[0035] The base of the electric kettle has a sealing ring added to the upper end of the coupler 2, and a seal is formed between adjacent sealing rings, which can effectively isolate water droplets from entering the coupler 2, avoid short circuits, achieve a sealing effect, and solve the problem of safety hazards caused by water entering the coupler 2 of the electric kettle.
[0036] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
