[0002] As people's living standards are getting higher and higher, most people have habitually stepped into the ranks of health preservation. At home, they generally drink boiled water heated by an electric kettle or use boiled water to make tea, etc. Therefore, the electric kettle is an indispensable small household appliance in the family.

[0003] At present, electric kettles on the market generally include an electric kettle base, a lower coupler arranged at the center of the base, the kettle body itself, and an upper coupler arranged on the lower end surface of the kettle body itself and plugged into the lower coupler. A conductive ring is provided in the upper coupler, and a conductive spring is provided in the lower coupler. The conductive spring is provided in a through groove opened on the circumferential side wall of the lower coupler and protrudes radially inward / outward from the through groove. When boiling water, the conductive spring of the lower coupler contacts the conductive ring on the upper coupler to realize electrical conduction and boil the water.

[0004] As the existing electric kettle is used for a long time and boils water too many times, the conductive ring in the upper coupler will be covered with scale and oxidized to form an oxide film. However, the part of the existing conductive reed protruding from the through slot is set as an arc-shaped contact point. The arc-shaped contact point can easily lead to poor contact between the conductive reed on the lower coupler and the conductive ring on the upper coupler, making it impossible to achieve electrical connection, which in turn causes damage to the electric kettle. Utility Model Content

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a conductive reed and a lower coupler of an electric kettle, which solves the technical problem that the existing arc-shaped contact point easily leads to poor contact between the conductive reed on the lower coupler and the conductive ring on the upper coupler, making it impossible to achieve electrical connection.

DETAILED DESCRIPTION

[0031] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below with reference to the accompanying drawings and through specific implementation methods. Figure 1 The direction where the central axis of the middle and lower coupler 200 is located is defined as "inward". Figure 3 The center line segment cc is defined as the longitudinal direction of the conductive spring 100 .

[0032] Example 1:

[0033] See also Figure 1-Figure 5 As shown, the lower coupler 200 of the electric kettle proposed in the embodiment of the present invention includes a conductive reed 100. A through slot 201 is provided on the outer or inner wall of the outermost circle of the lower coupler 200. In this embodiment, the through slot 201 is provided on the inner wall of the outermost circle.

[0034] Specific combination Figure 2-Figure 5 As shown, the conductive spring 100 includes a fixing portion 1 connected to the lower coupler 200 , a connecting portion 2 connected to the fixing portion 1 , and an abutting structure 3 provided on the connecting portion 2 .

[0035] Furthermore, the fixing portion 1 is an L-shaped mounting bracket, and a mounting hole 11 is provided at a lateral end of the fixing portion 1. The L-shaped mounting bracket is a double-layer structure, which makes the connection between the conductive spring 100 and the lower coupling piece 200 more stable.

[0036] In this embodiment, the connecting portion 2 is along the lower coupler 200 Figure 1 The connecting portion 2 is arranged axially along the central axis of the lower coupler 200, and is located at the through-slot 201 of the lower coupler 200. The abutment structure 3 is provided on a side wall (inner sidewall) of the connecting portion 2. The abutment structure 3 protrudes outward (closer to the central axis of the lower coupling plate 200) relative to the through-slot 201 in the radial direction of the lower coupler 200 so as to abut against the conductive ring of the upper coupler. The abutment structure 3 has a sharp portion capable of damaging the conductive ring.

[0037] This embodiment of a conductive spring and lower coupler for an electric kettle employs a sharp abutment structure 3 disposed on a connecting portion 2. The sharp edge of the abutment structure 3 can damage the oxide film formed on the surface of the conductive ring of the upper coupler 200, thereby preventing oxidation from affecting the heating effect of the kettle. This solves the technical problem of existing arc-shaped contact points that easily lead to poor contact between the conductive spring on the lower coupler and the conductive ring on the upper coupler, resulting in an inability to achieve electrical connection.

[0038] Furthermore, the connecting portion 2 has a first end 21 connected to the fixing portion 1 and a second end 22 disposed opposite the first end 21. A "U"-shaped groove 23 is provided on the side of the second end 22 of the connecting portion 2 facing the fixing portion 1, so that the connecting portion 2 forms a first mounting piece 24 and a second mounting piece 25. It should be noted that the purpose of the "U"-shaped groove 23 is to prevent the sharp portion from excessively damaging the conductive ring when it mates with the upper conductive ring, acting as a transition buffer, thereby enhancing the elasticity of the first mounting piece 24 and the second mounting piece 25. Moreover, the provision of the "U"-shaped groove 23 divides the connecting portion 2 into two parts that contact the mounting piece 25, that is, there are two contact points with the conductive ring. Compared with the conventional single contact point, the two contact points have better reliability.

[0039] Furthermore, the sharp portion includes four tooth-shaped abutment pieces 31, and the four tooth-shaped abutment pieces 31 are arranged in pairs at the second ends 22 of the two mounting pieces. The two tooth-shaped abutment pieces 31 on each mounting piece are symmetrically arranged, and the two tooth-shaped abutment pieces 31 are both located in the longitudinal direction of the mounting piece where they are located. Figure 3 The line segment cc is at the edge of the longitudinal axis. This position facilitates molding and simplifies the process. Moreover, the four tooth-like structures abut the pieces 31 to achieve a better destructive effect, further ensuring the conductive effect.

[0040] In addition, it should be noted that in this embodiment, when the electric kettle is used to boil water, the conductive ring of the upper coupler and the sharp part of the lower coupler of the kettle base can be cleaned autonomously to ensure the use of the electric kettle.

[0041] Furthermore, the tooth-shaped contact piece 31 is perpendicularly arranged to the first mounting piece 24 / the second mounting piece 25, and a plurality of serrations 311 are provided on the edge of the tooth-shaped contact piece 31. The serration structure has more sharp parts, thereby achieving a better contact effect.

[0042] Furthermore, the guide structure 4 includes two guide pieces 41, which are respectively connected to the transverse edges of the second ends 22 of the first mounting piece 24 and the second mounting piece 25. The guide pieces 41 are arc-shaped guide pieces 41 that are curved inward (actually radially outward) relative to the through slot 201. They can scrape off the oxide film on the conductive copper ring from multiple directions, thereby improving the conductive effect.

[0043] Example 2:

[0044] See also Figure 6As shown, the sharp portion includes two tooth-like abutment pieces 31, which are disposed on the first mounting piece 24 and the second mounting piece 25, respectively. The tooth-like abutment pieces 31 are located at the longitudinal edges of the first mounting piece 24 / the second mounting piece 25. Compared to Example 1, this embodiment differs in the number and distribution of the tooth-like abutment pieces 31. This embodiment has fewer tooth-like abutment pieces 31, reducing costs and simplifying the process.

[0045] Example 3:

[0046] See also Figure 7 As shown, the sharp portion includes two groove structures 31', one located on the first mounting piece 24 and the other on the second mounting piece 25. Furthermore, the groove structures 31' are formed at the longitudinal edges of the first mounting piece 24 / second mounting piece 25, forming semicircular arc-shaped sharp edges 311' on the first mounting piece 24 / second connecting piece 25. Compared to the two previous embodiments, which differ in manufacturing and molding methods, this embodiment has a simpler molding process and a sharper edge than the previous two embodiments, resulting in a more effective descaling effect.
