Problems solved by technology

[0002] When brushing your teeth manually, brushing your teeth along the gap between the teeth, 1. It does not conform to the habit of arm movement
2. It is difficult to control the intensity and magnitude
The cleaning effect is not good, and it is prone to damage to teeth and gums
The existing electric toothbrush uses a rotating brush head to brush teeth, which is easy to wear teeth and damage the gums, and it is not easy to clean the gaps between the teeth. The size of the brush head cannot be adjusted and cannot adapt to different sizes of teeth.
When the electric toothbrush is used for a long time, the motor will generate heat if it runs for too long, and the service life of the electric toothbrush will be greatly shortened if the single use time is too long

Embodiment Construction

[0021] The invention patent will be described in detail below in conjunction with the accompanying drawings.

[0022] Such as Figure 1 to Figure 6 As shown, the brush handle 1 and the brush head 2 are connected as one, and the brush handle 1 is provided with a battery slot 3, and a battery is installed in the battery slot 3, which can be replaced at any time, which is convenient and convenient. The battery is electrically connected through the battery slot 3 and the motor 4 that is also arranged in the brush handle 1 . The brush handle 1 is also provided with a speed regulating switch 13, which can adjust the rotating speed of the motor 4 by setting different gear positions. The motor 4 is connected with a transmission shaft, the transmission shaft is composed of a straight shaft 5 and a crankshaft 6, and the straight shaft 5 and the crankshaft 6 are connected as one, the straight shaft 5 extends from the motor 4 to the inside of the brush head 2, and the crankshaft 6 is arr...

Abstract

The invention discloses an electric toothbrush.A battery is installed in a battery groove.A speed regulating switch is switched on, a motor rotates to drive a straight shaft to rotate, and thus a crankshaft is driven to rotate.A concave-convex path part carries out circular motion with the straight shaft as a circle center point and carries out vertical movement in a crankshaft sliding groove of driving sliding blocks, and the driving sliding blocks carry out horizontal reciprocating motion on the concave-convex path part.The adjacent driving sliding blocks carry out relative horizontal motion to keep the relative balance of a brush head.Through simple circular motion, brush bristles move in the direction of gaps between teeth, a scientific tooth brushing method is achieved, the cleaning effect is better, teeth and gingiva are not likely to be hurt, and meanwhile the amplitude of reciprocating motion can be regulated; in addition, the speed can be regulated, tooth brushing is more comfortable, and efficiency is higher.

Description

technical field [0001] The patent of the present invention relates to a toothbrush, in particular to an electric toothbrush that is easy to clean and prolongs the service life, and can also change the size of the brush head according to the size of the tooth cavity. Background technique [0002] When brushing teeth manually, brushing teeth along the teeth, 1. It does not conform to the habit of arm movement. Second, the intensity and range are difficult to control. The cleaning effect is not good, and it is prone to damage to teeth and gums. The existing electric toothbrush adopts a rotating brush head for brushing teeth, which is easy to wear teeth and damage gums, and is not easy to clean between the teeth. When the electric toothbrush is used for a long time, the motor will generate heat if it runs for too long, and the service life of the electric toothbrush will be greatly shortened if the single use time is too long. Contents of the invention [0003] In order to ...
