[0025] The top of the cutter head part 2 is provided with a cutting plane 5, and the top of the cutter net cover 1 is provided with a contact plane 61. The top of the cutting plane 5 abuts against the inner wall of the contact plane 61. The top of the cutter net cover 1 is obliquely provided with a contact side surface 62. The contact plane 61 and the contact side surface 62 are connected to form a circular truncated cone-shaped contact surface 6. A plurality of strip-shaped grooves 7 are uniformly arranged on the circular truncated cone-shaped contact surface 6. Each strip-shaped groove 7 is in communication with the lifting cavity. The groove width of the strip-shaped groove 7 is not less than one ninth of the radius of the contact plane 61.

[0026] When the driving mechanism drives the support assembly 4 to rotate, the cutting plane 5 at the top of the cutter head part 2 is rotated to cut the hair entering from each strip-shaped groove 7.

[0027] Working principle of the embodiment 1:

[0028] When the composite shaving razor is used, first, the driving mechanism starts the motor to drive the support assembly 4 to rotate. The rotation of the support assembly 4 drives the cutting plane 5 at the top of the cutter head part 2 to rotate. The cutting plane 5 abuts against the contact plane 61, so that accurate shaving is performed in the process of hair contact. The strip-shaped grooves 7 on the cutter net cover 1 provide a channel for the hair to smoothly enter the cutting area, and the groove width design ensures that each hair can be fully cut.

[0029] The cooperation of the limiting assembly 3 and the lifting cavity enables the cutter head part 2 to be lifted and lowered to adapt to the curves of different skin parts, ensuring the comfort and safety during shaving. In addition, the circular truncated cone-shaped contact surface 6 design of the contact plane 61 and the contact side surface 62 enables the shaving razor to better adapt to the contour of the skin, reducing irritation and damage to the skin. At the same time, when the cutter net cover 1 contacts the user's skin, both the contact plane 61 and the inclined contact side surface 62 can be used, so it can be applied to various shaving scenarios, improving the functional applicability and use range of the shaving razor.

[0030] In addition, through the cooperation design of the lifting cavity, the limiting assembly 3 and the support assembly 4 in the embodiment, the position and rotation of the cutter head part 2 can be accurately controlled, so as to realize the optimal contact angle between the cutter head and the skin. This not only improves the shaving precision, but also ensures the uniformity and thoroughness of the shaving process, avoiding the situation that the traditional shaving razor may not be clean or residual hair.

[0031] Preferably, the included angle between the contact side surface 62 and the vertical plane is in the range of 10°-30°.

[0032] Specifically, in the embodiment, the included angle between the contact side surface 62 and the vertical plane is 17°.

[0033] Preferably, as Figure 1As shown, the center of the contact plane 61 is provided with a center surface 8, and the center of the cutting plane 5 is provided with a center groove 9, which is located below the center surface 8, and the width of the center groove 9 is matched with the diameter of the center surface 8.

[0034] Specifically, in the embodiment, the center groove 9 is arranged in the center of the cutting plane 5, so that the area of the cutting plane 5 is reduced, and the manufacturing cost of the cutting plane 5 is reduced.

[0035] Preferably, referring to Figure 3 The limiting assembly 3 comprises a limiting sleeve 31, a first limiting piece 32 and a second limiting piece 33, the limiting sleeve 31 is fixedly sleeved at the bottom of the cutter head part 2, the first limiting piece 32 and the second limiting piece 33 are fixedly sleeved on the limiting sleeve 31 from top to bottom, and the first limiting piece 32 and the second limiting piece 33 are in sliding connection with the lifting cavity.

[0036] Specifically, in the embodiment, the first limiting piece 32 and the second limiting piece 33 are arranged in an up-down distribution structure, so that the uniformity of the sliding connection between the limiting assembly 3 and the lifting cavity is realized.

[0037] Embodiment 2, which is the second embodiment of the application, is different from the previous embodiment in that the first embodiment provides a first chip groove 34 and a second chip groove 35, which can improve the cleaning ability of the hair debris and avoid the accumulation of the hair debris, wherein a plurality of first chip grooves 34 and a plurality of second chip grooves 35 are arranged on the first limiting piece 32 and the second limiting piece 33 respectively, and each second chip groove 35 is located below the corresponding first chip groove 34.

[0038] Working principle of embodiment 2:

[0039] When the cutting plane 5 is attached to the contact plane 61, the hair enters the cutting plane 5 from each strip groove 7 and is cut into debris in the process of contacting the cutting plane 5, and part of the debris enters the lifting cavity and accumulates, and after the support assembly 4 stops rotating, the hair debris falls downward from the first chip groove 34 and the second chip groove 35, thereby avoiding the accumulation of the hair debris and improving the self-cleaning ability of the hair debris.

[0040] Embodiment 3, referring to Figure 4For the third embodiment of the application, unlike the previous embodiment, this embodiment provides a support base 41, an elastic connecting piece 42 and a driving connecting piece 43, which can improve the fitting degree of the cutting plane 5 and the contact plane 61 and improve the cutting effect on the hair. The support assembly 4 comprises the support base 41, the elastic connecting piece 42 and the driving connecting piece 43. The support base 41 is fixedly connected to the lower end of the limiting sleeve 31. The driving connecting piece 43 is located below the support base 41. The two ends of the elastic connecting piece 42 are fixedly connected to the support base 41 and the driving connecting piece 43, respectively. The bottom of the driving connecting piece 43 is provided with a plurality of driving connecting grooves. Each driving connecting groove is used to connect the driving mechanism.

[0041] Working principle of embodiment 3:

[0042] When the driving connecting piece 43 is driven to be pressed towards the support base 41, the gap between the cutting plane 5 and the contact plane 61 is compressed to be smaller, the elastic connecting piece 42 is compressed to accumulate elastic potential energy, at this time, the fitting degree of the cutting plane 5 and the contact plane 61 is higher, and the cutting effect on the hair is improved. When the pressing force between the driving connecting piece 43 and the support base 41 decreases, the elastic connecting piece 42 rebounds to release the elastic potential energy, and the gap between the cutting plane 5 and the contact plane 61 becomes larger. By setting this structure, the gap between the cutting plane 5 and the contact plane 61 is conveniently and quickly adjusted.

[0043] Preferably, a plurality of limiting grooves 44 are formed on the support base 41, and a plurality of limiting blocks 45 are arranged on the driving connecting piece 43. The limiting blocks 45 are located below the limiting grooves 44. When the driving connecting piece 43 is driven to move towards the support base 41, each limiting block 45 extends into the corresponding limiting groove 44.

[0044] Specifically, in this embodiment, the cooperation of the limiting blocks 45 and the limiting grooves 44 effectively limits the movement range of the driving connecting piece 43, ensures the accurate positioning and stability of the driving piece, and thus avoids the deviation or instability that may occur during the movement. At the same time, the cooperation of the limiting blocks 45 and the limiting grooves 44 also enhances the reliability of the overall structure. When the driving connecting piece 43 moves towards the support base 41, the extension of the limiting blocks 45 can effectively prevent the components from colliding or being damaged due to excessive movement, thereby prolonging the service life of the equipment and reducing the frequency of maintenance and repair.

[0045] Preferably, the tool bit part 2 is also provided with a reinforcing inclined surface 10, which is located below the cutting plane 5 and is used to support the cutting plane 5.

[0046] Specifically, in this embodiment, the reinforcing slope 10 is located below the cutting plane 5, which can effectively support the cutting plane 5 and enhance the overall structural stability of the cutter head 2. During shaving or cutting, the cutting plane 5 bears a large force, and through the support of the reinforcing slope 10, the deformation or loosening of the cutter head 2 caused by external force can be reduced, thereby ensuring the long-term stable operation of the shaving razor.

[0047] At the same time, the design of the reinforcing slope 10 can effectively improve the overall rigidity of the cutter head 2, ensuring that the cutting plane 5 maintains the correct angle and position. This support structure can ensure that the cutter head always maintains the ideal cutting state during use, improving cutting efficiency and reducing the situation of incomplete shaving caused by changes in the position of the cutter head during use.

[0048] Finally, the arrangement of the reinforcing slope 10 helps to evenly distribute the stress of the cutter head 2, avoiding the problem of excessive or insufficient local stress that may exist in traditional designs. This not only prolongs the service life of the cutter head 2, but also improves the reliability and durability of the shaving razor.
