[0027] Reference Figures 1-7 A reciprocating electric toothbrush includes a main body housing 1, a brush head body 2, and a bristle-embedded round head 3. The bristle-embedded round head 3 is installed at one end of the brush head body 2. The brush head body 2 is a thin-walled, nearly 90-degree curved tube-shaped body with a first vertical mounting cavity and a second mounting cavity intersecting it at a nearly perpendicular angle. The first mounting cavity is used to install an inner shaft 13, and the second mounting cavity is used to install the bristle-embedded round head 3. The back of the main body housing 1 is provided with an anti-slip pad.

[0028] The main unit housing 1 houses a reciprocating rotating component, which includes a bottom cover 4, a bracket 8, a PCBA board 9, a motor 10, an output shaft 11, and an inner shaft 13. The bottom cover 4 is installed at one end of the main unit housing 1. The brush head body, the bristle-forming round head 3, the bottom cover 4, and the inner shaft 13 together form the rotating brush head. The main unit housing 1 is a tubular shell with two mounting cavities, one smaller at the front and one larger at the back. The bracket 8 is installed on the inner wall of the larger mounting cavity, and the smaller mounting cavity is used to install the output shaft 11. The PCBA board 9 is fixedly connected to the bracket 8. The motor 10 is installed at one end of the bracket 8, and a battery is located at the other end of the bracket 8. The output shaft 11 is installed on the battery. On the motor 10, the end of the output shaft 11 away from the motor 10 is fixedly connected to the inner shaft 13. One end of the inner shaft 13 is fixedly connected to the bristle-planting round head 3. The inner shaft 13 is installed in the first mounting cavity of the brush head body 2. Its head is connected to the bristle-planting round head 3, and the other end is connected to the output shaft 11. The bottom cover 4 is equipped with a charging terminal 16. The bottom cover 4 is provided with a charging port and a sealing device. The bracket 8, battery and PCBA board 9 together form the core. The main body shell 1, the core and the bottom cover 4 together form the main body of the electric toothbrush. The bristle-planting round head 3 is disc-shaped. Its disc surface is arranged with bristle-planting holes. The opposite back of its disc is provided with a device for installing and connecting the inner shaft 13.

[0029] The inner shaft 13 is rotatably connected to the brush head body 2. The bristle-planting round head 3 is round and has multiple bristle-planting holes. One end of the brush head body 2 is fixedly connected to a tail cap 14. The end of the tail cap 14 away from the brush head body 2 is fixedly connected to the main unit housing 1. The PCBA board 9 is a printed circuit board, which is the core component of various electronic products. It is responsible for connecting various electronic components together so that the entire electronic product can work normally. A switch button 6 and a mode button 7 are installed on the outer surface of the PCBA board 9. The outer surface of the main unit housing 1 is fixed. A decorative piece 5 is connected to the switch button 6, which is slidably connected to the decorative piece 5. A mode button 7 is slidably connected to the decorative piece 5. A waterproof bushing 12 is fitted between the output shaft 11 and the bracket 8. The waterproof bushing 12 is used to prevent water from entering the PCBA board 9 on the bracket 8 and causing damage. The output shaft 11 is slidably connected to the waterproof bushing 12. A waterproof cover 15 is installed on the lower surface of the bottom cover 4. The waterproof cover 15 can cover the charging port on the bottom cover 4 to prevent the charging terminal 16 inside the charging port from contacting the water outside.

[0030] In this invention, pressing the switch button 6 activates the PCBA board 9, which in turn controls the motor 10 to start working. The motor 10 controls the output shaft 11 to extend and retract. Since the other end of the output shaft 11 is connected to the inner shaft 13, the output shaft 11 drives the inner shaft 13 to reciprocate linearly, causing the bristle-filled round head 3 at the front end of the inner shaft 13 to rotate and swing left and right. The bristles on the bristle-filled round head 3 will act on the surface of the user's teeth, thereby cleaning the teeth comprehensively and increasing the cleaning area of ​​the electric toothbrush. The user does not need to frequently move the electric toothbrush body back and forth. While ensuring comprehensive cleaning of teeth, it is also convenient for the user and reduces physical exertion. Pressing the mode button 7 activates the PCBA board 9, which controls the motor 10 to adjust the extension and retraction speed of the output shaft 11, thereby allowing the rotation speed of the bristle-filled round head 3 to be adjusted for different users.

[0031] The main unit casing 1 can be sealed by the tail cap 14 and the waterproof cap 15. When the battery inside the main unit casing 1 is depleted, simply open the waterproof cap 15. After the waterproof cap 15 is opened, the charging terminal 16 inside the tail cap 14 is exposed to the external environment. At this time, simply contact the tail cap 14 on the main unit casing 1 with the charging base that comes with the electric toothbrush. The charging terminal 16 inside the tail cap 14 will then be inserted into the charging base, allowing the charging base to quickly charge the battery inside the main unit casing 1 through the charging terminal 16. The entire charging process does not require removing the battery from the main unit casing 1, which is convenient for charging the electric toothbrush and avoids water entering the electric toothbrush due to battery removal, thus reducing the failure rate of the electric toothbrush. At the same time, in daily use, the cooperation of the waterproof bushing 12, the sealing ring 17 on the tail cap 14, and the waterproof cap 15 ensures that the electric toothbrush is in a sealed state, preventing water from entering the main unit casing 1 during brushing and causing damage to the PCBA board 9, thereby improving the safety and service life of the electric toothbrush.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.
