[0024] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0025] like Figure 1 and 2 As shown, a skin grinding head in an embodiment of the utility model comprises a rotating head 1 and a plurality of convex teeth 2 arranged at intervals on the outer surface of the rotating head 1 .

[0026] It can be understood that by arranging a plurality of convex teeth 2 on the outer surface of the rotating head 1, the convex teeth 2 can grind the skin when following the rotation of the rotating head 1, thereby reducing the size of the wound caused by the skin grinding head, thereby reducing the patient's pain, facilitating the subsequent healing of the wound and making the patient's skin as scar-free as possible.

[0027] like Figure 1 and 2 As shown, in this embodiment, the rotating head 1 is cylindrical, and a plurality of protruding teeth 2 are arranged on the outer peripheral surface of the rotating head 1. In other embodiments, the rotating head 1 may be spherical, ellipsoidal, dumbbell-shaped, etc.

[0028] In a specific embodiment, the rotating head 1 is a rotating head 1 made of silicon, and the protruding teeth 2 are protruding teeth 2 made of silicon. Preferably, the rotating head 1 and the protruding teeth 2 are both made of silicon.

[0029] Preferably, the rotating head 1 and the convex teeth 2 are integrally formed. Such a design can improve the connection strength and stability of the rotating head 1 and the convex teeth 2, and facilitate the processing and manufacturing of the skin grinding head.

[0030] Specifically, along the axial direction of the rotating head 1, a plurality of convex teeth 2 are spaced apart on the outer peripheral surface of the rotating head 1; along the circumferential direction of the rotating head 1, a plurality of convex teeth 2 are spaced apart on the outer peripheral surface of the rotating head 1. Such an arrangement can make the convex teeth 2 more evenly distributed, thereby ensuring uniformity in grinding the skin.

[0031] Preferably, in Figure 1 In the embodiment shown, a plurality of protruding teeth 2 are spaced apart along the axial direction and the circumferential direction of the rotary head 1. Along the axial direction of the rotary head 1, the spacing between adjacent protruding teeth 2 is equal; along the circumferential direction of the rotary head 1, the spacing between adjacent protruding teeth 2 is equal.

[0032] like Figure 1 and Figure 2As shown, in this embodiment, the outer surface of the convex tooth 2 includes a first surface 23 and a second surface 24, and a grinding line 25 is formed at the connection between the first surface 23 and the second surface 24. That is, the connection between the first surface 23 and the second surface 24 is the grinding line 25. The first surface 23 and the second surface 24 are curved surfaces extending in different directions. That is, during the skin grinding process, when the rotation direction of the rotating head 1 is Figure 2 In the clockwise direction, the grinding line 25 plays the role of grinding the skin.

[0033] Compared with the existing metal film head that is in surface contact with the skin, the utility model has the grinding line 25 in contact with the skin, that is, line contact, thereby reducing the contact area between the skin grinding head and the skin, reducing the size of the wound caused by the skin grinding head on the skin, thereby reducing the patient's pain, facilitating the later healing of the wound and making the patient's skin as scar-free as possible.

[0034] like Figure 4 In another embodiment shown, the protruding tooth 2 includes a connecting portion 21 connected to the outer surface of the rotating head 1, and a tip 22 extending outward from the connecting portion. When the skin grinding head is working, that is, when the rotating head 1 drives the protruding tooth 2 to rotate, the tip 22 contacts the skin. The rotating direction of the rotating head 1 is Figure 4 The tip 22 can be rotated in a clockwise or counterclockwise direction, and the tip 22 has the grinding effect of a skin grinding head.

[0035] Compared with the existing metal film head that is in surface contact with the skin, the tip 22 of the utility model is in contact with the skin, thereby reducing the contact area between the skin grinding head and the skin, reducing the size of the wound caused by the skin grinding head on the skin, thereby reducing the patient's pain, facilitating the healing of the wound in the later stage, and making the patient's skin as scar-free as possible.

[0036] Furthermore, Figure 1 and Figure 2 In the embodiment shown, the convex tooth 2 includes a connecting portion 21 connected to the outer surface of the rotating head 1, and a tip 22 extending outward from the connecting portion. The tip 22 bends and extends outward from the connecting portion. When the skin grinding head is working, that is, when the rotating head 1 drives the convex tooth 2 to rotate, the tip 22 contacts the skin. Figure 2 In the counterclockwise direction, the tip 22 plays the role of a skin grinding head to grind the skin.

[0037] Preferably, Figures 1 to 3 As shown, the protruding tooth 2 includes a connecting portion 21 connected to the outer surface of the rotating head 1, and a tip portion 22 extending outward from the connecting portion 21, and the tip portion 22 is provided with a first receiving hole 26; the rotating direction of the rotating head 1 is Figure 2 The counterclockwise direction in the figure, and the bending direction of the tip 22 is also Figure 2 In the counterclockwise direction, the first receiving hole 26 plays the role of taking the skin, and the rotating head 1 drives the convex teeth 2 along the Figure 2 When the skin grinding head rotates counterclockwise, the skin grinding head can grind the skin and collect some skin fragments into the first receiving hole 26, which plays the role of removing skin. At this time, the skin wound is smaller, which is convenient for the healing of the skin wound. Figure 2 When the tooth 2 is rotated clockwise, the grinding lines on the convex teeth 2 play a role in grinding the skin, for example, grinding the tissue to be removed from the skin.

[0038] In a specific embodiment, the first receiving hole 26 can also be used to accommodate medicine for skin treatment or care; for example, hyaluronic acid or the like can be placed in the first receiving hole 26 for daily facial massage and care.

[0039] Furthermore, the outer surface of the protruding tooth 2 is provided with a second receiving hole 27, and the aperture of the second receiving hole 27 is smaller than the aperture of the first receiving hole 26. The outer surface of the protruding tooth 2 may be provided with a plurality of second receiving holes 27, and the second receiving holes 27 may also be used to receive drugs, thereby increasing the amount of drugs received on the protruding tooth 2.

[0040] It is understandable that the first receiving hole 26 and the second receiving hole 27 can be formed on the protruding tooth 2 by laser drilling. As the rotating head 1 rotates, the medicine in the first receiving hole 26 and the second receiving hole 27 can flow out of the first receiving hole 26 and the second receiving hole 27 to the skin surface under the action of centrifugal force.

[0041] Preferably, the height of the protruding teeth 2 is 0.4-1 mm. The size of the protruding teeth is 0.2-0.3 mm.

[0042] like Figure 2 As shown, in this embodiment, the axial end face of the rotating head 1 is provided with a connecting hole 11, and the connecting hole 11 is used to connect with the driving mechanism. Specifically, the output end of the driving mechanism can be plugged into the connecting hole 11, and the output end of the driving mechanism and the connecting hole 11 are interference fit, snap-fit ​​or other fixed connection methods. The driving mechanism can be an electric rotary machine sold on the market. In this embodiment, the driving mechanism is not a part of the skin grinding head.

[0043] A specific embodiment of the utility model further provides a skin grinding device, including a driving mechanism (not shown in the figure) and a skin grinding head as described above, wherein the driving mechanism includes a rotatable output end, and the skin grinding head is connected to the output end.

[0044] Preferably, the axial end face of the rotating head 1 is provided with a connecting hole 11, and the connecting hole 11 is used to connect with the driving mechanism.
