Embodiment 1

[0036] see Figure 1 to Figure 3 , the present invention provides a fuse-proof anti-dry kettle coupler, including a panel 1, a central rod 2, a first terminal ring 3, a second terminal ring 4, a connecting piece 5, a first terminal 6, and a second terminal 7 , bimetal disc 8, ceramic rod 9, fuse device and bracket body 10;

[0037] The central rod 2 stands at the center of the panel 1, the first terminal ring 3 and the second terminal ring 4 are ring-shaped and respectively surround the periphery of the central rod 2 inside and outside; the bracket body 10 is connected and fixed to the panel 1, and the first terminal 6 and the The second terminals 7 are respectively fixedly installed on the support body 10, and the ends of the first terminal 6 and the second terminal 7 are respectively fixedly provided with a fixed contact; The two terminal rings 4 are electrically connected, and the other end of the connecting piece 5 is fixedly provided with a moving contact, and the two mo...

Embodiment 2

[0046] The only difference between this embodiment and Embodiment 1 is that this embodiment adopts the design of two bimetallic discs 8, and the two electrodes composed of the first terminal ring 3 and the second terminal ring 4 are simultaneously applied with bimetallic discs. Chip 8 self-resetting anti-dry burning power-off protection.

[0047] see Figure 4 Specifically, as a preference, the bimetallic disc 8 is provided with two pieces, which are respectively arranged directly above the two connecting pieces 5, and the two connecting pieces 5 and the two bimetallic discs 8 are respectively provided with A ceramic rod 9; one of the connecting pieces 5 is also connected with the fuse device.

[0048] Two bimetallic discs 8 act on the two electrodes respectively, the principle of which is to make the ceramic rod 9 protrude from the connecting piece 5 when the heat jumps, so that the fixed contact is disconnected from the movable contact. The fuse device independently perfor...

Embodiment 3

[0053] see Figure 5 , The only difference between this embodiment and Embodiment 1 and Embodiment 2 is that a heat conduction extension 16 is added for direct heat conduction, which accelerates the reaction speed of the fuse rod 11 and improves the safety of the product.

[0054] Preferably, the top of the fuse rod 11 is provided with a heat conduction extension 16 extending upwards for connection with external heat conduction; the heat conduction extension 16 extends upwards and is exposed on the surface of the panel 1 . Then, when the present invention is installed on the bottom of the heating plate of the kettle, the heat conduction extension 16 can directly contact with the heating plate, and the heat of the heating plate will be directly transmitted to the fuse rod 11, so that the fuse rod 11 can be more rapid, sensitive, Respond directly, greatly improving security.

[0055] This structure is further added on the basis of the solution of Embodiment 1 or Embodiment 2, a...

Abstract

The invention provides a dry-burning preventing kettle coupler with fusing. The dry-burning preventing kettle coupler comprises a surface plate, a central rod, a first terminal ring, a second terminal ring, connecting pieces, a first terminal, a second terminal, double metal discs, a ceramic rod, a fusing device and a bracket body, wherein the first terminal and the second terminal are respectively fixedly mounted on the bracket body; fixed contacts are respectively fixed arranged at the terminal parts of the first terminal and the second terminal; one end of each connecting piece is electrically connected with the first terminal ring and the second terminal ring respectively; one moving contact is fixedly arranged at the other end of each connecting piece; two moving contacts are respectively propped against fixed contacts on two terminals movably; the centers of the double metal discs are fixedly connected with disc mounting parts; the ceramic rod is propped against the edges of the double metal discs so that the fixed contacts and the moving contacts are in normal closed power on / off connection; the fusing device is connected with one of the connecting pieces so that the fixed contacts and the moving contacts are in normal closed power on / off connection. By virtue of the fusing device, the security property can be further ensured.

Description

technical field [0001] The invention relates to the field of household electrical appliances, in particular to a dry-boiling-proof kettle coupler with fusing. Background technique [0002] As a commonly used household appliance, electric kettle has been widely used in household and catering occasions, which facilitates people's daily drinking water needs. In general use, add an appropriate amount of water into the electric kettle, and then place the electric kettle on the supporting base to heat the water with electricity. For safety reasons, the kettle coupler is an important part to ensure the safety of the electric kettle. [0003] Existing kettle couplers all rely on two bimetallic strips to implement anti-dry protection to prevent users from playing the role of anti-dry protection when using the electric kettle by misoperation or when the steam switch fails. When anhydrous dry burning occurs, the protection temperature of the bimetal strip is reached, and the bimetal ...
