The rotation direction of the second output member 42 is opposite to that of the first output member 41. The brush head 2 comprises a first brush holder 21 connected to the first output member 41, and a second brush holder 22 connected to the second output member 42. Both the first brush holder 21 and the second brush holder 22 have bristles 23. Since the facial cleansing brush is constantly moving during use, the staggered reverse rotation of the double brush heads during use can make the facial skin subject to tension in different directions, thereby improving the cleaning intensity while taking into account comfort.

[0031] As a further improvement of the present invention, the second brush holder 22 is annularly arranged around the outer peripheral surface of the first brush holder 21; the second brush holder 22 is arranged in a surrounding manner, so that the two brush holders rotating in opposite directions can fit closely together, and can contact the facial skin over a larger area, thereby improving the cleaning effect; forming a massage effect, the alternating pressure and relaxation exerted on the skin by the bristles 23 under reverse rotation can not only effectively remove dirt, but also promote blood circulation.

[0032] As a further improvement of the present utility model, the outer peripheral surface of the first brush holder 21 is provided with a mating groove 211 connected end to end, and the second brush holder 22 is provided with a mating protrusion 221 inserted into the mating groove 211 and capable of sliding along the mating groove 211, so that the first brush holder 21 can rotate relative to the second brush holder 22; the design of the mating groove 211 and the mating protrusion 221 ensures a reliable connection between the two brush holders and allows relative rotation.

[0033] As a further improvement of the present invention, a first boss 222 is provided on the rear surface of the second brush holder 22, and a second boss 421 abutting against the first boss 222 is provided on the front surface of the second output member 42 to drive the second brush holder 22 to rotate; the stability and reliability of the rotation of the brush holder are ensured through direct contact between the first boss 222 and the second boss 421.

[0034] As a further improvement of the utility model, the transmission device 4 includes a first gear 43 connected to the output shaft of the driving device 3, a second gear 44 meshing with the first gear, a third gear 45 arranged on the second gear 44 and rotating synchronously with the second gear 44, a fourth gear 46 meshing with the third gear 45, a fifth gear 47 arranged on the fourth gear 46 and rotating synchronously with the fourth gear 46, and a sixth gear 48 meshing with the fifth gear 47. The first output member 41 is arranged on the sixth gear 48 and rotates synchronously with the sixth gear 48. The second output member 42 is annular, and the inner side of the annular shape of the second output member 42 is provided with an inner tooth 422 meshing with the fifth gear 47.

[0035] It should be noted that the structure of the transmission device 4 can be various. For example, the fifth gear 47 may not mesh with the sixth gear 48, but may be set on the second gear 44 and rotate synchronously with the second gear 44. The utility model adopts multi-gear step-by-step transmission to adjust the output speed and torque, thereby realizing effective rotation of the brush holder and avoiding the bristles 23 from being unable to rotate when encountering resistance.

[0036] Embodiment 2:

[0037] Reference Figure 4-10 In order to solve the technical problem, the utility model also provides a rotary facial cleansing brush, including a body 1 and a brush head 2. A driving device 3, a first output member 41 and a second output member 42 are arranged in the body 1. A transmission device 4 is connected between the first output member 41 and the second output member 42 and the driving device 3 to drive the first output member 41 and the second output member 42 to rotate around their own axes. The rotation direction of the second output member 42 is opposite to that of the first output member 41. The brush head 2 includes a first brush holder 21 connected to the first output member 41, and a second brush holder 22 connected to the second output member 42. The first brush holder 21 is provided with a plurality of bristle members 212 and a brush holder transmission assembly 213 that can drive all the bristle members 212 to rotate around their own axes. The second brush holder 22 has bristles 23.

[0038] By providing a brush holder transmission assembly 213 on the first brush holder 21, the rotation speed or direction of the bristle member 212 can be adjusted, and the combination of the bristles 23 and a plurality of bristle members 212 can rotate alternately, so that the facial skin is subjected to pulling forces in different directions, thereby improving the cleaning intensity while taking into account comfort.

[0039] As a further improvement of the present invention, the second brush holder 22 is provided with a plurality of bristle through holes 223 corresponding one-to-one to the bristle members 212, and the brush holder transmission assembly 213 includes a seventh gear 2131 arranged on the first brush holder 21 and a plurality of eighth gears 2132 corresponding one-to-one to the bottom of the bristle members 212 and meshing with the seventh gear 2131.
