A fixing block passes through the through hole, and its two ends are respectively fixed into the two opposite mounting slots. A space is provided between the fixing block and the through hole for the brush head holder to rotate left and right. In the space, the lower end of the round pin passes through the first pin hole at the top of the through hole and the second pin hole on the fixing block and is inserted into the connecting hole of the brush head seat. The upper end of the round pin is limited to the limiting shaft hole at the bottom of the brush seat groove. A transmission rod is slidably provided in the extension direction inside the transmission bracket. A flange is provided in the middle of the transmission rod. A secondary spring and a main spring are respectively sleeved on the transmission rod on both sides of the flange. One end of the secondary spring is fixedly pressed on the flange, and the other end is fixedly pressed on the transmission bracket. One end of the main spring is fixedly pressed on the flange, and the other end is pressed against the transmission bracket. A transmission pin is fixed on the rear side of the brush head seat, and the transmission hole at the inner end of the transmission rod is sleeved on the transmission pin.

[0006] A buffer is connected to the outer end of the transmission rod.

[0007] The inner section of the transmission rod is bent to one side at an angle.

[0008] The brush head body has several mounting slots on its side wall for mounting connectors and transmission brackets. The connectors and transmission brackets are provided with mounting protrusions that mate with the mounting slots for installation.

[0009] The advantages of this invention are: practicality, novel structure, low noise, comfortable vibration, and good cleaning effect. Attached Figure Description

[0017] A novel rotary electric toothbrush head includes a brush head body 1 and a brush head base 9. A connector 2 for detachable connection to an electric toothbrush is fixed inside the brush head body 1 near its rear end. Brush bristles 11 for cleaning teeth are fixed to the front side of the brush head base 9 via a brush blade 10. A transmission bracket 13 is fixed to the middle section inside the brush head body 1. Two mounting slots 102 are oppositely formed on the wall of the brush seat groove 101 at the front end of the brush head body 1. A through hole 901 is provided on the rear side of the brush head base 9. A fixing block 12 passes through the through hole 901, and its two ends are respectively fixed into the two opposite mounting slots 102. A space is provided between the fixing block 12 and the through hole 901 for the brush head base 9 to rotate left and right. A round pin 7 is lowered... The first pin hole 902 at the top of the through hole 901 and the second pin hole 1201 on the fixing block 12 are inserted into the connecting hole 903 of the brush head seat 9. The upper end of the round pin 7 is limited to the limiting shaft hole 103 at the bottom of the brush seat groove 101. A transmission rod 6 is slidably provided in the extension direction inside the transmission bracket 13. A flange 601 is provided in the middle of the transmission rod 6. A secondary spring 4 and a main spring 5 are respectively sleeved on the transmission rod 6 on both sides of the flange 601. One end of the secondary spring 4 is fixedly pressed on the flange 601, and the other end is fixedly pressed on the transmission bracket 13. One end of the main spring 5 is fixedly pressed on the flange 601, and the other end is pressed against the transmission bracket 13. A transmission pin 8 is fixed on the rear side of the brush head seat 9. The transmission hole 602 at the inner end of the transmission rod 6 is sleeved on the transmission pin 8.

[0018] In use, this invention allows for a detachable plug-in connection between the connector 2 and the main body of the electric toothbrush, similar to existing technologies. After the invention is attached to the main body of the electric toothbrush, the buffer 3 is tightly attached to the main unit inside the main body. When the main unit is turned on, it vibrates, which moves the buffer 3 to the transmission rod 6, causing the transmission rod 6 to swing back and forth. The transmission rod 6 then drives the brush head seat 9, brush blade 10, and bristles 11 to swing through the transmission pin 8. The fixing block 12 holds the brush head seat 9 and bristles 10 in place, preventing them from falling off. Under the action of the main spring 5, the transmission rod 6 has a force that allows it to return to its original position. The secondary spring 4 provides assistance, support, and buffering. As the transmission rod 6 moves back and forth, it drives the brush head seat 9 to rotate back and forth through the transmission pin 8 connected to its front end, allowing the bristles 11 on the brush head seat 9 to clean the teeth.

[0019] The outer end of the transmission rod 6 is connected to a buffer 3, which has a good buffering effect and can effectively reduce the noise generated by the impact.

[0020] The inner section of the transmission rod 6 is bent to one side at an angle, making the transmission smoother.

[0021] The brush head body 1 has several mounting slots 104 for mounting connectors 2 and transmission brackets 13 on its side wall. Both the connectors 2 and the transmission brackets 13 are provided with mounting protrusions 213 for mounting in conjunction with the mounting slots 104.
