[0001] The utility model relates to the technical field of skin cleaners, in particular to a rotating skin cleaning head with a brush head adaptive telescopic structure. Background Art

[0002] A rotating skin cleaning head is a beauty tool for cleaning the skin. The skin cleaning head has an efficient cleaning effect. Through the rotating motion, it can more effectively remove dirt, grease and aged keratin on the skin surface, which is more thorough than the traditional manual cleaning method; gentle and skin-friendly: it will not cause excessive stimulation and damage to the skin while cleaning; massage effect: the rotating motion can play a certain massage role, promote blood circulation of the skin, and enhance the metabolism of the skin; multifunctional design: some rotating skin cleaning heads are also equipped with different brush heads or functional modes to meet different skin types and cleaning needs, such as deep cleaning, blackhead removal, soothing massage, etc. Generally, a rotating skin cleaning head is usually driven by a motor to drive the brush head or the cleaning surface to rotate. When the cleaning head contacts the skin, the rotating motion generates friction to loosen and remove dirt and impurities on the skin surface. However, the existing device has a uniform contact force between the brush head and the skin, and the face is not particularly flat, so the contact between the brush head and the face is not sufficient. Therefore, the present application proposes a rotating skin cleaning head in which the brush head adapts to the flatness of the face and then adjusts the brush head by telescopic adjustment. Utility Model Content

[0033] AsFigures 1 - 5 As shown, the rotary skin cleaning head with a brush head adaptive telescopic structure proposed by the utility model comprises a brush head housing 1, a housing cavity 11 is provided in the brush head housing 1, and a rotary cleaning mechanism 2 is installed in the housing cavity 11. Specifically, the rotary cleaning mechanism 2 comprises a driving motor 21 installed in the housing cavity 11, the output end of the driving motor 21 is rotatably connected to the top inner wall of the housing cavity 11, a large gear 22 is sleeved and installed on the outer ring of the output end of the driving motor 21, and a plurality of small gears 23 are provided on the outer periphery of the large gear 22 in meshing transmission, and a rotating shaft 24 is fixedly installed through the inner ring of the small gear 23, and the rotating shaft 24 is installed on the bottom inner wall of the housing cavity 11 through a bearing.

[0034] like Figure 2 As shown, a sleeve rod 27 is provided on the top of the pinion gear 23 , a micro cylinder 28 is fixedly connected to the bottom of the sleeve rod 27 , and a base of the micro cylinder 28 is fixedly connected to the top of the pinion gear 23 .

[0035] For further information, please refer to Figure 3 A guide rod 25 is fixedly connected to the top of the rotating shaft 24, and a rectangular hole is provided on the inner wall of the sleeve rod 27 to match the outer part of the guide rod 25. The arrangement of the guide rod 25 and the rectangular hole can make the rise of the sleeve rod 27 more stable. A buffer spring 26 is fixedly connected to the top of the guide rod 25, and the top end of the buffer spring 26 is connected to the top of the rectangular hole of the sleeve rod 27. A rotating plate 29 protruding from the brush head housing 1 is fixedly connected to the top of the sleeve rod 27. A plurality of lifting holes 12 are provided on the top of the brush head housing 1. The sleeve rod 27 passes through the lifting holes 12 and the outer diameter of the rotating plate 29 is larger than the maximum inner diameter of the lifting holes 12. A brush head cover 4 is installed on the top of the rotating plate 29, and the brush head cover 4 is a silicone soft cover.

[0036] Among them, Figure 4 , Figure 5 As shown, the bottom of the brush head cover 4 is also provided with a pressure sensor 3 located on the top of the rotating plate 29 , and each group of pressure sensors 3 is connected to the micro cylinder 28 via a radio signal.

[0037] The working principle in this embodiment is as follows: The large gear 22 is rotated by the drive of the drive motor 21. The large gear 22 meshes with the small gear 23, causing the small gear 23 to synchronously rotate the top rotating shaft 24, guide rod 25, sleeve rod 27, and rotating plate 29, thereby achieving the purpose of rotating the brush head sleeve 4. Thus, the brush head sleeve 4 will clean the face. During the process of the brush head sleeve 4 rotating for cleaning, the pressure sensor 3 continuously monitors the pressure of the contact between the brush head sleeve 4 and the face. When the contact pressure between the brush head sleeve 4 and the face is insufficient, the pressure sensor 3 sends a signal to the control end of the corresponding micro cylinder 28, and starts to push through the output end of the micro cylinder 28, achieving the purpose of pushing the sleeve rod 27 along the lifting hole 12. During the process of the sleeve rod 27 being pushed upward along the guide rod 25, the buffer spring 26 is stretched, making the pushing of the sleeve rod 27 more stable. Thus, the contact pressure of the brush head sleeve 4 on the face becomes larger under the same pressing state, enabling the brush head sleeve 4 to fully contact and clean the sunken facial features, and the cleaning is more thorough.

[0038] The above specific embodiments are merely several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
