Problems solved by technology
[0003] However, whether it is a rotating motor or a vibrating motor, it has a certain service life and a high cost, so that the price of a traditional electric toothbrush remains high, which has brought a great impact on the promotion and use of electric toothbrushes. At the same time, because people often turn off and start the rotating motor or vibration motor frequently when turning or changing sides, the service life of the core drive of the electric toothbrush is greatly reduced, which brings additional costs to the use cost of the electric toothbrush. increase

The invention discloses a driving mechanism of a torsional electronic toothbrush, relates to the field of electronic toothbrush structures, and in particular relates to improvement of a toothbrush head driving mechanism. The invention discloses a driving mechanism which is precise in structure, good in stability, good in tooth cleaning effect, low in manufacturing cost and low in use cost for a torsional electronic toothbrush. The driving mechanism comprises an electromagnet, a sliding block, a rotating base, a limiting component and two elastic pieces, wherein the electromagnet is fixedly connected inside a brush stem of an electronic toothbrush and is connected with a battery of the electronic toothbrush; the sliding block is connected in the brush stem in a sliding manner; a gap is formed between the sliding block and the electromagnet; the rotating base is moveably connected with one end of the brush stem and is connected the head of the electronic toothbrush; an included angle between the two elastic pieces is an acute angle. The driving mechanism has the advantages of being precise in overall structure, good in stability, good in tooth cleaning effect, low in manufacturing cost and low in use cost.
Description
technical field [0001] The invention relates to the structural field of electric toothbrushes, in particular to the improvement of the driving mechanism of the brush head. Background technique [0002] At present, most electric toothbrushes are divided into two categories: rotary type and vibrating type. Among them, the rotary type electric toothbrush is driven by a motor to rotate the round brush head, so as to enhance the friction effect while performing ordinary toothbrush actions; while the vibrating type electric toothbrush is The brush head is driven by the vibration motor to oscillate at high frequency, so as to effectively clean the dirt between the teeth. [0003] However, whether it is a rotating motor or a vibrating motor, it has a certain service life and a high cost, so that the price of a traditional electric toothbrush remains high, which has brought a great impact on the promotion and use of electric toothbrushes. At the same time, because people often turn ...
