Problems solved by technology

However, in actual use, consumers still have the problem of poor experience
For example, if the water-filling arm encounters an obstacle (such as a person holding the water-filling arm) during use, the motor will be stuck and the water-filling arm cannot continue to rotate, which will shorten the service life of the motor or even burn the motor

Abstract

The invention discloses an over-torque protection transmission mechanism, a driving mechanism and an electric kettle, and belongs to the field of household appliances. The over-torque protection transmission mechanism comprises a first rotating part and a second rotating part, wherein the first rotating part has a circular groove coaxial with the first rotating part, and the inner circumferentialsurface of the circular groove is provided with a plurality of embedding grooves; the second rotating part comprises an embedded convex part, an elastic reset part, and a rotating main body; the embedded convex part is provided with protruding parts which can be embedded into the embedding grooves; one side of the rotating main body is provided with a sliding way for fitting and sliding of the embedded convex part; the elastic resetting part is located in the sliding way and abuts against the embedded convex part; after the protruding parts are embedded into the corresponding embedding grooves, when the torsion force between the first rotating part and the second rotating part is larger than the embedding force between the protruding parts and the corresponding embedding grooves, the embedded convex part compresses the elastic resetting part so that the protruding parts are separated from the corresponding embedding grooves. The first rotating part and the second rotating part are connected with a driving device and a driven part for transmission, so that transfer of over-high torsion force from the driven part to the driving device can be avoided, and damage to the driving devicecan be prevented.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an over-torque protection transmission mechanism, a drive mechanism and an electric kettle. Background technique [0002] With the improvement of people's living standards and the acceleration of the pace of life, more and more household appliances have entered consumers' homes to meet people's various needs, and the functions and application scenarios of such home appliances are becoming more and more refined. , to enhance the consumer experience. For example, an electric kettle is provided with a water-filling rotary arm, and the rotation of the motor drives the water-filling rotary arm to add water to the kettle. However, in actual use, consumers still have the problem of poor experience. For example, during use, when the water-filling arm rotates, it encounters an obstacle (for example, a person holds the water-filling arm with a hand), and the motor is stuck a...
