Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a multi-functional electric toothbrush.

Background Art

[0002] It is very difficult to remove dental plaque by using a traditional toothbrush. When using a traditional toothbrush in an improper way, the cleaning effect of the traditional toothbrush will be greatly reduced, and even serious damage to the gums and teeth may be caused. With the progress of technology, people's requirements for living standards are constantly improving. Electric toothbrushes have gradually been recognized by the market because they can avoid the harm of traditional toothbrushes and bring fun to people at the same time. However, when using the existing electric toothbrush to clean teeth, the brush head can only clean teeth in one direction, and the brush handle needs to be continuously rotated; moreover, when cleaning different parts of the teeth, the brush handle needs to be continuously pushed and pulled, resulting in a poor use experience.

The present utility model realizes the functions of the brush head assembly reciprocally moving clockwise or counterclockwise and axially telescoping through the cooperation of the drive motor, the synchronous motion mechanism and the telescopic mechanism, which is convenient for the user to clean teeth in multiple directions and at multiple angles, and has the characteristics of high practicability and multi-functionality. In addition, the present utility model only needs one drive motor to simultaneously realize the reciprocating swing and telescopic motion of the brush rod assembly, has the advantages of simple structure and low manufacturing cost, effectively reduces its overall weight, and improves the market competitiveness of the product.
