Swing type motor capable of feeding back output swing and used in cooperation with electric toothbrush

Abstract

The invention discloses a swing type motor matched with an electric toothbrush for use and capable of feeding back output swing amplitude, which comprises a shell, an output shaft is rotatably arranged in the shell, a rotor iron core is arranged on the output shaft, a permanent magnet is arranged in the rotor iron core, stator iron cores are respectively arranged on two sides of the rotor iron core of the shell, and a permanent magnet is arranged in the stator iron core. The stator core is wound with a coil, the generator further comprises a power generation winding and a magnetic part, the power generation winding is connected with an external operation module, the operation module is arranged outside the shell and connected with the shell, the magnetic part is arranged close to the power generation winding, and the power generation winding and the magnetic part are arranged in a relative movement mode. The structure is simple, the rotation amplitude of the output shaft can be effectively fed back, and the using effect of the overall structure is effectively improved.

Description

technical field [0001] The invention relates to the technical field of electric toothbrush components, in particular to an oscillating motor with feedback output swing used in conjunction with an electric toothbrush. Background technique [0002] Electric toothbrush is a new product that has become popular in recent years, and has set off a revolution in the field of oral health care abroad. With the widespread popularity of electric toothbrushes in our country, and with the improvement of people's awareness of it, electric toothbrushes will also become an important member of public health care products. The survey shows that compared with ordinary toothbrushes, electric toothbrushes are more scientific and effective, and can more thoroughly remove plaque, reduce gingivitis and gingival bleeding. Electric toothbrushes use the rapid reciprocating rotation of the motor output shaft to generate high-frequency vibration of the brush head. , so that the toothpaste is decomposed ...

Problems solved by technology

The survey shows that compared with ordinary toothbrushes, electric toothbrushes are more scientific and effective, and can more thoroughly remove dental plaque, reduce gingivitis and gum bleeding. Electric toothbrushes use the rapid reciprocating rotation of the motor output shaft to generate high-frequency vibrations on the brush head , so that the toothpaste is decomposed into fine foam in an instant, and the gap between the teeth is deeply cleaned; at present, the motor in the electric toothbrush usually uses an AC motor, so that the left and right swing of the electric toothbrush head is realized, and the purpose of cleaning the teeth is realized. Among the existing electric toothbrush motors , usually includes a stator assembly, a housing, and a rotor assembly. The rotor assembly includes a rotating shaft and a rotor core. The rotor core is fixedly connected to the rotating shaft. A bearing is provided on the rotating shaft. The rotating shaft is combined with the housing through the bearing to realize the reciprocating rotation of the rotating shaft. However, the existing motor lacks an output feedback mechanism, and the rotation angle of the motor output shaft cannot be well determined, which makes it difficult to adjust the gear output of the current electric toothbrush and reduces the use effect. At the same time, due to the lack of feedback mechanism, it affects the development and use of subsequent toothbrushes. Reduce user experience
