Problems solved by technology
For example, the patent that the notification number is CN2555802Y discloses a kind of electric toothbrush mechanism, and this patent drives the rotation of the toothbrush head by the cam mechanism installed inside the toothbrush handle; Internally, the vibration of the cam mechanism during the start-up operation of the electric toothbrush will be transmitted to the hand of the toothbrush user, causing discomfort to the user
In addition, during the actual operation of the drive mechanism and cam mechanism of this electric toothbrush, it is prone to the problem of relatively large vibration and noise due to the contact and friction between their internal parts, which makes the user use the electric toothbrush. poor experience

The invention discloses a rotary electric toothbrush which comprises a brush head, a handheld body, a transmission mechanism used for driving the brush head to rotate in a reciprocating mode and a driving mechanism arranged in the handheld body and connected with the transmission mechanism. One end of the brush head shell is arranged at the front end of the handheld body, and a mounting groove communicated with an inner cavity of the brush head shell is formed in the side face of the other end of the brush head shell. The brush head is rotatably arranged in the mounting groove; a groove is formed in the brush head, and the transmission mechanism is provided with an eccentric part; the transmission mechanism penetrates through the inner cavity of the brush head shell and enables the eccentric part to be matched with the groove so as to drive the brush head to rotate in a reciprocating mode. Through the structure, the noise caused by excessive vibration of the handheld main body part in the tooth brushing operation process of the rotary electric toothbrush can be reduced to a great extent, and the use experience effect of a user can be improved.
Description
technical field [0001] The present invention relates to the technical field of toothbrushes, in particular to a rotary electric toothbrush. Background technique [0002] The invention of the electric toothbrush has brought people a lot of convenience, but the large vibration and noise of the electric toothbrush has always been a common problem of the electric toothbrush. At present, in the electric toothbrush industry, most rotary electric toothbrushes are driven by adding a cam mechanism inside the hand-held body of the electric toothbrush, and the cam mechanism converts the output force of the motor into the rotation of the toothbrush head, thereby driving the brush head. The reciprocating rotation to achieve the brushing action. For example, the patent publication number CN2555802Y discloses an electric toothbrush mechanism, which drives the rotation of the toothbrush head through a cam mechanism installed inside the toothbrush handle; since the drive mechanism and cam m...
