It should be explained that, except that the core 112 is used as a support, the driving structure 120 may be installed, a main board and a charging interface may be further disposed on the core 112, the main board integrates a control circuit and is connected to the driving structure 120, the charging interface is connected to the main board and may be exposed from the body 111 to the installation cavity 101, so that a user may charge a power supply disposed on the core 112 through the charging interface exposed from the installation cavity 101.

The cutter head assembly 200 comprises a housing 210 and a blade structure 220 disposed in the housing 210, the blade structure 220 can be understood as the blade set, the blade structure 220 is connected to the driving structure 120, specifically, a motor in the driving structure 120 is connected to the blade structure 220, and the motor can drive the blade structure 220 to rotate, so that the hair entering the housing 210 is cut by the rotation of the blade structure 220.

A driving switch 300 is disposed between the housing 210 and the main body 110, and the driving switch 300 can close a control circuit where the blade structure 220 is located, so as to trigger the driving structure 120 to drive the blade structure 220 to rotate. The driving switch 300 can be turned off to be electrically disconnected from the control circuit, and the driving structure 120 cannot drive the blade structure 220 to rotate, so that the operation of the hair shaving apparatus 10 is stopped.

The housing 210 can rotate in a circumferential direction relative to the body 110 to switch between an open position and a closed position. Specifically, the housing 210 and the cover 113 are axially limited, and the housing 210 and the cover 113 can rotate circumferentially relative to each other, and at this time, the driving switch 300 is disposed between the housing 210 and the cover 113. Further, referring to fig. 4, one of the housing 210 and the cover 113 is provided with a first hook 410, the other is provided with a second hook 420, and the first hook 410 and the second hook 420 are in a clamping fit, i.e. the first hook 410 and the second hook 420 hook each other to complete the limit, so as to realize the axial limit and the circumferential rotation of the housing 210 and the cover 113.

The number of the opening positions and the closing positions is multiple, and the opening positions and the closing positions are alternately arranged along the circumferential direction. In the on position, the driving switch 300 turns on the control circuit to trigger the driving mechanism 120 to rotate the blade structure 220, and in the off position, the driving switch 300 turns off the control circuit.

To describe in more detail, referring to fig. 2 and 4, the driving switch 300 includes a pressing elastic arm 310 and an electronic switch 320, the pressing elastic arm 310 has a fixed end 311 and a pressing end 312, the fixed end 311 is disposed on one of the cover 113 and the housing 210, fig. 4 illustrates that the fixed end 311 is disposed on the cover 113, the housing 210 and the cover 113 can rotate relatively, so that the pressing end 312 can overcome the elastic resistance of the pressing elastic arm 310 to press the electronic switch 320, and further the electronic switch 320 is turned on and conducts the control circuit, and when the electronic switch 320 is conducted on the control circuit, the blade structure 220 can complete the cutting of the hair under the driving of the driving structure 120. When the housing 210 and the cover 113 rotate to the circumferential closed position, the pressing end 312 can be separated from the electronic switch 320 by the elastic force of the pressing elastic arm 310. It can be understood that when the latch arm 310 is pressed to release the electronic switch 320 again by rotating one gear, the control circuit is opened.

When the housing 210 rotates relative to the cover 113, the first protrusion 510 can press the second protrusion 520 toward the side of the electronic switch 320 and the pressing end 312 presses the electronic switch 320, and at this time, the relative position of the housing 210 and the cover 113 can be understood as the open position. The second protrusion 520 can be located between two adjacent first protrusions 510 after the rotation of one shift position is completed, so that the pressing end 312 is separated from the electronic switch 320 by the elastic restoring force of the pressing elastic arm 310 to complete a key pressing action, and the relative position of the housing 210 and the cover 113 can be understood as a closed position. When the housing 210 rotates relative to the cover 113, in order to switch between the open position and the closed position, two sides of the first protrusion 510 moving along the circumferential direction may be set as a curved surface or an inclined surface, and similarly, two sides of the second protrusion 520 moving along the circumferential direction may also be set as a curved surface or an inclined surface, so that the housing 210 and the cover 113 may not only rotate along the clockwise direction, but also rotate along the counterclockwise direction. If only one-way rotation of the housing 210 relative to the cover 113 is desired, the first protrusion 510 and the second protrusion 520 only need to be provided with a curved surface or an inclined surface along the same side of the circumferential movement.

It should be noted that, in the closed position, two opposite sides of the second protrusion 520 along the circumferential direction respectively contact and abut against two adjacent first protrusions 510, so that, unless the force for driving the housing 210 and the cover 113 to rotate relatively is large enough, the relative positions of the housing 210 and the cover 113 cannot be easily dislocated, and the stability of the device in the closed position can be ensured. Similarly, in order to ensure the stability of the device when being in the open position, the shaving apparatus 10 of the present invention may further include a limiting groove 313 on the pressing elastic arm 310, and fig. 4 shows that the limiting groove 313 is located between the fixed end 311 and the pressing end 312, and of course, the specific position of the limiting groove 313 should not be limited to the above position, and may be set at any other position. When one of the first bumps 510 presses the second bump 520 to the push electronic switch 320, the other different first bump 510 is engaged in the retaining groove 313 to maintain the current open position. The first protrusion 510 located in the limiting groove 313 can also be separated from the limiting groove 313 along the groove wall of the limiting groove 313, and the relative rotation force between the driving shell 210 and the cover 113 can drive the first protrusion 510 to move along the groove wall of the limiting groove 313, which can be realized by setting the side wall of the limiting groove 313 along the circumferential direction as an inclined surface or a curved surface.

Referring to fig. 5, in the shaving apparatus 10 according to the embodiment of the present invention, the housing 210 is rotatable in the circumferential direction with respect to the main body 110, and the housing 210 is switchable between a plurality of open positions and a plurality of closed positions in the circumferential direction during the rotation with respect to the main body 110. In the on position, the driving switch 300 is connected to the control circuit to trigger the driving structure 120 to rotate the blade structure 220. In the closed position, the driving switch 300 is turned off from the control circuit, thereby stopping the process of driving the blade structure 220 by the driving structure 120. It can be seen that the present invention provides a shaving apparatus 10 that facilitates the opening and closing of the shaving apparatus 10 for operational use by a user, particularly in situations requiring multiple switch uses, and that can be continuously rotated in one direction to effect alternate switching between opening and closing, while maintaining overall appearance integrity.

When the cover 113 covers the movement 112 on the body 111, a sealing ring 114 is arranged on the side circumference of the cover 113, and the sealing ring 114 shown in fig. 5 is positioned between the body 113 and the cover 113, so that external water vapor can be ensured to enter the body 113, and the use safety of elements on the movement 112 is ensured.

It will be appreciated that the drive block 213 may also be disposed on the outside wall of the knife housing 211. The screw cover 212 is axially limited with the cover 113 and can rotate relative to the cover 113 in the circumferential direction, and a plurality of tooth grooves 214 are formed in the side wall of the screw cover 212 at intervals in the circumferential direction. The knife shell 211 can drive the driving block 213 to selectively cooperate with different tooth slots 214 along the axial direction, so that the knife shell 211 can drive the screw cap 212 to synchronously rotate. Based on the above structure, when the user needs to use a different razor head, or needs to replace the razor head due to the service life of the razor head, the user can use the cutter housing 211 away from the rotary cap 212 very conveniently. It should be noted that, since the number of the tooth slots 214 is plural, the blade housing 211 to which the blade structure 220 is attached can be fitted to the screw cap 212 along the direction of the tooth slot 214 at plural different angles in the circumferential direction.

In order to increase the convenience of the positioning installation of the knife shell 211 and the screw cap 212 and increase the stability of the matching of the two. A magnetic assembly may be disposed between the knife case 211 and the screw cap 212, and the magnetic assembly includes a first magnetic component and a second magnetic component, the first magnetic component and the second magnetic component are respectively disposed on the knife case 211 and the screw cap 212, and the first magnetic component and the second magnetic component are capable of attracting magnetically, so that the knife case 211 and the screw cap 212 are aligned and close to each other under the action of magnetic force to complete the matching. It should be noted that, at least one of the first magnetic member and the second magnetic member is a magnet, and the other may be a magnetically attractable metal or a magnet.
