When the output shaft <NUM> of the servo motor <NUM> drives the connector on the eccentric shaft <NUM> to make a circular motion, the connector can synchronously drive the hair removal component <NUM> to move along a preset trajectory. In the embodiment, since the movement trajectory of the connector is circular, the movement trajectory of the hair removal component <NUM> is also circular; moreover, since the connector is clearance fitted in the connecting sleeve <NUM>, the hair removal component <NUM> itself will not rotate circumferentially along the center.

In order to avoid the loosening of the hair removal component <NUM> caused by the clearance fit of the connector inside the connecting sleeve <NUM>, in the embodiment, a limiting component is also connected between the second side of the hair removal component <NUM> and the shell <NUM>, and the limiting component is used to ensure that the hair removal component <NUM> moves along a preset trajectory when the servo motor <NUM> drives the hair removal component <NUM> to rotate. The limiting component comprises a limiting ring <NUM> connected to the second side of the hair removal component <NUM> and a limiting column <NUM> connected to the shell <NUM>. The diameter of the limiting ring <NUM> is the diameter of the movement trajectory of the connector, and the limiting column <NUM> is fitted to the inner wall of the limiting ring <NUM>. When the hair removal component <NUM> rotates synchronously with the connector, the limiting column <NUM> rotates along the inner wall of the limiting ring <NUM>, thus effectively limiting the shaking or loosening of the hair removal component <NUM>. Further, the number of limiting components can be two or more, preferably two in the embodiment. The limiting ring <NUM> can be arranged on the hair removal component <NUM> or the shell <NUM>, and the corresponding limiting column <NUM> can be arranged on the shell <NUM> or the hair removal component <NUM>, which is not limited here.

In order to avoid the loosening of the hair removal component <NUM> caused by the clearance fit of the connector inside the connecting sleeve <NUM>, in another specific embodiment, the second limiting part <NUM> is connected in the second connecting cavity 1041b through a bearing fit. In other embodiments, referring to <FIG>, the second side of the hair removal component <NUM> is provided with a hollow shaft sleeve <NUM>, and the connector and the connecting cavity <NUM> are of columnar structure instead of the above-mentioned T-shaped structure. The connector can be directly connected with the shaft sleeve <NUM> through a bearing fit, and when the connector drives the hair removal component to move along a preset trajectory, the hair removal component will not shake.

Further, in some embodiments, the shell <NUM> is provided with a holding groove for holding the hair removal component <NUM>. When the shape of the hair removal component <NUM> is irregular and it is difficult to rotate in the holding groove, it is necessary to push the hair removal component <NUM> out of the holding groove for rotation. In the embodiment, referring to <FIG>, a metal threaded rod <NUM> is connected to the second side of the hair removal component <NUM>, and the output shaft <NUM> of the servo motor <NUM> is fixedly connected with a metal threaded sleeve <NUM> adapted to the threaded rod <NUM>. The second side of the hair removal component <NUM> is also fixedly connected with an electromagnet <NUM>. The output shaft <NUM> of the servo motor <NUM> can drive the threaded sleeve <NUM> to rotate, and then the hair removal component <NUM> is pushed up and out through the threaded rod <NUM>. When the hair removal component <NUM> is pushed out, the electromagnet <NUM> is energized, and the electromagnet <NUM> attracts the threaded sleeve <NUM> and the threaded rod <NUM> into a whole. When the servo motor <NUM> drives the threaded sleeve <NUM> to rotate again, the hair removal component <NUM> can be driven to rotate synchronously. When it is necessary to store the hair removal component <NUM> in the holding groove, the electromagnet <NUM> is de-energized, and when the servo motor <NUM> drives the threaded sleeve <NUM> to rotate again, the hair removal component <NUM> is pushed down for storage through the threaded rod <NUM>.

Specifically, the circuit board is electrically connected with a speed gear adjustment component <NUM> for adjusting the driving component; the speed gear adjustment component <NUM> is connected with a speed gear adjustment button <NUM>, and different speeds can be switched by the speed gear adjustment button <NUM>, so that different speeds can apply to different hair removal situations, which greatly increases the application scenarios and improves the user experience. In a specific embodiment, three speed gears can be set, and the speed of the motor is controlled to gradually change from slow to fast through three different gears.

Specifically, a sealing component is connected between the output shaft <NUM> of the servo motor <NUM> and the shell <NUM>. The sealing component can prevent liquids such as water from entering the inside of the shell <NUM>, which avoids short circuit or corrosion of electronic elements and prolongs the service life of electronic elements. In a specific embodiment, the sealing component can be a silicone ring.

Further, referring to <FIG>, the outer side of the shell <NUM> is provided with a PV cell panel <NUM> electrically connected with the circuit board, and the PV cell panel <NUM> is used for absorbing solar energy and storing energy in the energy storage component <NUM>; the hair removal equipment of the product is designed with various charging modes, and charging with the PV cell panel <NUM> is beneficial to energy saving. It can be understood that the PV cell panel <NUM> absorbs energy in two ways: optical energy - thermal energy - electric energy conversion and direct optical energy - electric energy conversion.

Further, the circuit board is electrically connected with a charging component, and the charging component includes a charging port <NUM>. The charging port <NUM> runs through the shell <NUM>, and is provided with at least one of MiniUSB interface, MicroUSB interface, Type-c interface or Lightning interface; the charging port <NUM> can be provided with multiple interfaces, which are beneficial to application in various charging environments and improves the user experience. In the embodiment, the charging port <NUM> is provided with a silicone waterproof plug. The silicone waterproof plug can prevent liquids such as water from entering the inside of the shell <NUM>, which avoids short circuit or corrosion of electronic elements and prolongs the service life of electronic elements.

The hair removal device of the present disclosure comprises a shell <NUM> and a hair removal component <NUM> connected to at least one side of the shell <NUM>. The hair removal component <NUM> is provided with a hair removal surface <NUM> on the side facing away from the shell <NUM>. The hair removal surface <NUM> is provided with several pattern groups <NUM>, which are used for rubbing against the skin when the hair removal component <NUM> comes into contact with the skin so as to remove hair and dead skin on the skin surface. The hair removal device is ingenious in structural design and convenient to operate. When the hair removal surface <NUM> comes into contact with the skin, the main annular convex pattern touches the skin and rotates gently, and in the process of rotating and rubbing against the skin, the hair removal surface <NUM> grabs and pulls out or rubs off the hair on the skin surface and removes dead skin. Due to the annular structure of the main annular convex pattern, the adoption of the rotation and rubbing mode can reduce skin irritation, improve hair removal efficiency, remove hair from skin painlessly, and achieve the effect of smooth skin.
