AI Technical Summary

Problems solved by technology

The drive mechanism driven by the electric motor in the above-mentioned brush handle is well known and widely used. In the known art, there are various mechanical linkages including gears, which are used to convert the rotary motion of the electric motor into the rotation of the toothbrush head. Swing or other motion methods, but these machine devices are complex in structure, unreliable, expensive, and have a single purpose, especially a special toothbrush head with complex structure must be used, and the price of toothbrush heads on the market currently accounts for about 10% of the total price. 3096, the above reasons cause the electric toothbrush to be cost-effective and unable to be popularized

Abstract

The electric actuator includes casing, power source, motor connected to the power source, driving member connected to the rotating shaft of the motor, and magnet connected to a slender rod. The slender rod may be driven with the driving member to move back and forth. The multifunctional electric actuator may be connected with a toothbrush to constitute electric toothbrush or a massaging member to constitute massager. The electric toothbrush needs no special toothbrush head and has low cost.

Description

technical field [0001] The invention relates to the field of motors for electric toothbrushes and massagers. Background technique [0002] Existing massagers have various structures. Patent ZL96224551.8 discloses a massager. It sets an AC-DC transformer box and a DC motor in the massage stick, and sets an eccentric wheel on the DC motor shaft. The alternating current becomes direct current, and then the eccentric wheel is driven by the direct current motor to rotate at a high speed, and the undulating motion of the eccentric wheel is used to hit the affected part or acupoints to achieve the effect of massage and health care. The eccentric wheel of this structure directly acts on the rod shell, and the vertical vibration effect at the massage contact point is weak during use, the comfort is poor, and it is easy to damage. The invention of the application number 02246652.5 discloses two different massage modes with a structure of a massager to control the rotation or jumping ...
