Problems solved by technology
[0004] Based on this, in order to solve the problem that after the rice cooker cooks the rice, the thermal insulation sheet and the contact on the lever of the rice cooker will be sintered and stuck together, and the inner spring in the magnetic steel temperature limiter cannot drive the thermal insulation sheet to separate from the lever contact through the pull rod, and then To solve the problem of burning the magnetic steel temperature limiter or even causing a fire, the invention provides an external clamping device for the magnetic steel temperature limiter used in an electric rice cooker. The specific technical scheme is as follows:

Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with its embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0024] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

The invention provides a magnetic steel temperature limiter outer clamping device for an electric cooker, the electric cooker comprises a magnetic steel temperature limiter and a pull rod, the outer clamping device comprises a supporting frame, a bottom plate, a temperature sensing deformation part, a piston and a first telescopic assembly, a first inner cavity is formed in the bottom plate, the piston is in sliding connection with the side wall of the first inner cavity, and one end of the temperature sensing deformation part is fixedly connected with the piston. The first telescopic assembly comprises a first push rod, a first elastic component and first hydraulic cylinder sleeves, one end of the first push rod is arranged in the first hydraulic cylinder sleeve on the innermost layer in a sleeved mode, the first hydraulic cylinder sleeve on the outermost layer communicates with the first inner cavity, and a sealing cavity is formed among the piston, the first inner cavity and the first hydraulic cylinder sleeves. And the sealing cavity is filled with liquid. According to the invention, the problem that the magnetic steel temperature limiter is burnt due to the fact that a heat preservation sheet and the contact on a lever of the electric cooker are sintered and adhered together and the inner spring in the magnetic steel temperature limiter cannot drive the heat preservation sheet to be separated from the contact of the lever through the pull rod after the rice is cooked by the electric cooker can be solved.
Description
technical field [0001] The invention relates to the technical field of electric rice cookers, in particular to an external clamping device for a magnetic steel temperature limiter used in electric rice cookers. Background technique [0002] Rice cookers generally include a magnetic steel temperature limiter and a thermal insulation sheet. The magnetic steel temperature limiter is a temperature controller with hard and soft magnets. It belongs to a mechanical device that can realize automatic power-off of rice cookers. It is mainly composed of soft magnets without magnetism and hard magnets with permanent magnetism. When the hard magnet is close to the soft magnet at room temperature, the magnetic field of the hard magnet will magnetize the soft magnet, and then the two will be adsorbed. When the temperature rises to the Curie temperature point of the soft magnet, the magnetism of the soft magnet will decrease or even disappear, thus The two are separated under the elastic f...
