Fig. 2 is the structural representation when using the present invention to clean central incisors;

Fig. 3 is a schematic structural view of the first brush head in the present invention.

Detailed ways:

As shown in Figures 1-3, a new type of toothbrush includes a first brush head 1, a second brush head 2 that is fitted with a sliding fit on the first brush head 1, and is also hinged on the first brush head 1. brush handle3.

The first brush head 1 includes a first substrate 1a in the shape of a circular truncated or elliptical truncated platform, and a connecting rod 1b perpendicular to the substrate is provided at the center of the end surface of the first substrate 1a, and at the end of the connecting rod 1b A through hole 1f is provided. A group of first bristles 1c perpendicular to the first substrate are evenly distributed on the end surface of the first substrate 1a on the side of the connecting rod 1b. A group of bumps 1d are evenly distributed on the other end surface of the substrate 1a. Between the two side surfaces of the substrate 1a and the outer circular surface, a circle of rounded transition section 1e is provided.

A group of bristles 1g are evenly distributed on the outer wall of the connecting rod 1b on the side of the first bristles 1c, the axis of the bristles 1g is perpendicular to the axis of the connecting rod 1b, and there is a certain distance between the bristles 1g and the first bristles 1c.

The second brush head 2 includes a second base plate 2a corresponding to the first base plate 1a, and a mounting hole 2b corresponding to the connecting rod 1b is provided at the center of the second base plate 2a. A group of second bristles 2c perpendicular to the second substrate are evenly distributed on the opposite end surface of a bristle 1c. Through the mounting hole 2b, the second brush head 2 can be sleeved on the connecting rod 1b so that the second brush head 2 forms a sliding fit on the rod body of the connecting rod 1b.

A through groove 3 a is provided at one end of the brush handle 3 , and the bottom surface of the through groove 3 a is perpendicular to the axis of the brush handle 3 . The top 3c of the groove wall of the through groove 3a is arc-shaped, and the groove wall of the through groove 3a is also provided with a hinged hole 3b correspondingly matched with the through hole 1f, and the connecting rod 1b is connected with the connecting rod 1b by setting a pin in the hinged hole 3b.
