[0033] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0034] Please also read Figures 1 to 5 The present embodiment discloses a self-expanding facial cleaning assembly, which is assembled on the driving shaft of the facial cleaning instrument, and includes a facial cleaning brush assembly seat 10, a first brush body 20, and a second brush body 30. A card slot 14 is provided in the middle of the facial cleaning brush assembly seat 10, and the structure of the card slot 14 is adapted to the driving shaft of the facial cleaning instrument. The facial cleaning brush assembly seat 10 is connected to the driving shaft of the facial cleaning instrument through the card slot 14, so that the facial cleaning brush assembly seat 10 rotates along the rotating shaft, and three steering shafts 11 are provided on the surface of the facial cleaning brush assembly seat 10 around the center. The first brush body 20 includes a first base 21 and a first brush head. The first base 21 is provided with a steering shaft fixing hole 22 and a friction extension part 23. The first base 21 is sleeved on the steering shaft 11 through the steering shaft fixing hole 22. The length of the friction extension part 23 is greater than the radius of the facial brush assembly seat 10. The first base 21 is eccentrically arranged on one side of the steering shaft fixing hole 22. The first brush head is assembled on the friction extension part 23. The second brush body 30 includes a second base 31 and a second brush head. The steering shaft 11 is a hollow shaft. The second base 31 is provided with an assembly column adapted to the hollow structure of the hollow shaft, and is plugged into the steering shaft through the assembly column. The area where the second brush head of the second base 31 is located covers the steering shaft 11 of the facial brush assembly seat 10 and the area where the steering shaft fixing hole 22 of the first brush body 20 is located.

[0035] According to the above structure, during the use of the self-expanding facial cleansing assembly, the facial cleansing brush assembly seat is plugged into the driving shaft of the facial cleansing instrument through the card slot, fixed by friction, or fixed by the mutually matching protrusions and grooves on the facial cleansing instrument driving shaft and the card slot. Then, the power supply of the facial cleansing instrument is started, the facial cleansing instrument driving shaft rotates, and the facial cleansing instrument assembly seat is driven to rotate through the card slot. The facial cleansing instrument assembly seat in the rotating state drives the first brush body and the second brush body to rotate through the steering shaft. The first brush body provided on the friction extension portion of the first brush body contacts the face, and the friction force is the torque generated by the steering shaft fixing hole of the first brush body. The torque causes the first brush body to expand along the center of the steering shaft fixing hole in the opposite direction of the rotation direction of the facial cleansing brush assembly seat. The length of the friction extension portion is greater than the radius of the facial cleansing brush assembly seat, so that the friction extension portion can expand the cleaning area of ​​the friction extension portion after expansion. The second brush body plugged into the end of the hollow shaft is a cleaning area formed by the protrusion of the friction extension of the first brush body. When a smaller area of ​​the face needs to be cleaned, it can be cleaned through the protruding second brush body. When the face is cleaned, the power of the facial cleanser is turned off, the drive shaft stops rotating, and then the first brush bodies are closed. After cleaning, the face cleaning process is completed. By setting a facial cleansing brush assembly seat, a first brush body and a second brush body, the first brush body is eccentrically assembled on the steering shaft, and the steering shaft is arranged around the center of the facial cleansing brush assembly seat, so that when the first brush body contacts the face during the rotation of the facial cleansing brush, the friction force acts on the first brush body, and the first brush body rotates along the steering shaft through the eccentrically arranged steering shaft fixing hole, so that the first base uses the friction force of the eccentrically arranged friction extension part, and then the torque generated on the steering shaft is unfolded in the opposite direction of the rotation direction of the facial cleansing brush assembly seat, so that the first brush body is unfolded by friction force, the structure is simple, stable and labor-saving, and the cleaning area of ​​the brush body is increased, and the assembly improves the cleaning efficiency of the user's face. In the storage state, the folded first brush body is matched with the size of the face-cleansing assembly seat, thus avoiding space occupation and facilitating storage of the device.

[0036] Please also read Figure 1 as well as Figure 2 In some preferred embodiments, a positioning protrusion 24 and a positioning groove 25 with mutually matching sizes are provided on the first base 21 of the first brush body 20. The positioning groove 25 is provided on the side of the friction extension portion 23. When the first brush body is in the closed state, the positioning groove of one of the first brush bodies matches with the positioning protrusion of another first brush body provided in the rotation direction of the facial brush assembly base. By providing the positioning protrusion and the positioning groove, the first brush body in the closed state can be fixed by the positioning protrusion and the positioning groove in the storage state.

[0037] Please also read Figure 2 as well as Figure 3In some preferred embodiments, the facial cleansing brush assembly 10 further includes a damping member 12, and the damping member 12 corresponds to the first brush body 20 one by one. The first brush body 20 is provided with a damping groove 26, and the end of the damping member 12 faces the first brush body 20 and contacts the damping groove 26 or the positioning groove 25. In actual use, when the first brush body is in a closed state, the damping member contacts the damping groove, so that the first brush body can be stabilized in the closed state. When the first brush body is in an expanded state during operation, the end of the damping member can support the positioning groove to limit the first brush body. The state stability of the first brush body when it is in an expanded state is improved.

[0038] Please also read Figure 2 , Figure 3 as well as Figure 4 In some preferred embodiments, a clearance groove 27 is further included, and the clearance groove 27 is assembled on the first base 21. The size of the clearance groove 27 is adapted to the size of the area of ​​the first brush body 20 where the steering shaft fixing hole 22 is provided. By providing the clearance groove, when the first brush body is in the closed state, a clearance operation is performed for the area provided at the steering shaft and the steering shaft fixing hole, so that the friction extension parts of the first brush body can be close to each other in the closed state, avoiding interference between the occupied space of the steering shaft and the area of ​​the first brush body where the steering shaft fixing hole is provided, and affecting the space that can be contracted by the first base in the closed state.

[0039] See also Figure 1 In the above embodiment, the number of the first brush bodies 20 is 3. In other embodiments, the number of the first brush bodies 20 may be 2, or the number of the first brush bodies may be 4 or more.

[0040] See also Figure 2 as well as Figure 3 In some preferred embodiments, the facial brush assembly 10 further includes a limit block 13, which is disposed on the facial brush assembly 10. The number of the limit blocks 13 corresponds to the number of the first brush bodies and is in contact with the first brush bodies. By providing the limit blocks 13, the angle of the first brush body in the unfolded state can be limited by the limit blocks.

[0041] In the above embodiment, the first brush head and the second brush head are selected from bristle brush heads, plastic brush heads or silicone brush heads. The bristle brush heads and plastic brush heads can be assembled through assembly holes arranged on the friction extension part of the first brush body and the second base of the second brush body. The silicone head can be fixed to the friction extension part of the first brush body and the second base of the second brush body by plugging, gluing or coating.

[0042] See also Figure 1In the above embodiment, the friction extension portion 23 and the second base 31 are arc-shaped structures. By setting the arc-shaped structure, they can adapt to the depression of the face when contacting the human face, thereby improving the cleaning efficiency.

[0043] In some preferred embodiments, the second brush body can pass through the gaps between the first brush bodies via positioning columns or protrusions and grooves to achieve interconnection with the face cleaning assembly seat, thereby avoiding deformation of the steering shaft caused by long-term use of the connection to the steering shaft.

[0044] In some preferred embodiments, the steering shaft may be preset with a bearing, and the steering shaft fixing hole of the first brush body is assembled on the bearing to reduce the resistance when the first brush body rotates, expands and closes.

[0045] It should be noted that, although the above embodiments have been described in this article, the patent protection scope of the present invention is not limited thereby.
