In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0040] like Figures 1 to 10 As shown, this application embodiment provides a cleaning device, including a housing 1, multiple cleaning brush assemblies 2, and a drive assembly 3; the cleaning brush assembly 2 includes a brush head 20 rotatably connected to the housing 1 and a phototherapy mechanism disposed on the brush head 20, the multiple brush heads 20 are arranged at intervals, the brush head 20 is used to clean the skin, the brush head 20 is provided with a light-transmitting part 28, the light-transmitting part 28 is disposed on the same side as the brush bristles 29 of the brush head 20, and the phototherapy mechanism projects light through the light-transmitting part 28; the drive assembly 3 is installed on the housing 1 and is drivenly connected to the brush head 20.

[0041] In related technologies, conventional cleaning devices include a housing 1 and a brush head 20 rotatably connected to the end of the housing 1, and the brush head 20 can only perform rotational cleaning.

[0042] In this embodiment, the housing 1 is provided with a plurality of brush heads 20 spaced apart from each other. Each brush head 20 is used to clean a certain area. These brush heads 20 are rotatably connected to the housing 1. The housing 1 is provided with a drive assembly 3, which drives and connects to these brush heads 20 to control the movement of the brush heads 20. When cleaning the skin, the multiple brush heads 20 work together to perform phototherapy on the skin. When the brush heads 20 move, they can rub a large area of ​​skin to clean it. They can also be used with skin cleansing agents, which are rubbed and foamed on the skin surface. Due to the combined action of the multiple brush heads 20, the user can quickly clean the skin, and even hard-to-reach areas can be covered. This setting optimizes the structure of the cleaning device, increases the cleaning range of the cleaning device, and improves the cleaning efficiency of the cleaning device.

[0043] In some embodiments, the cleaning brush assembly 2 further includes a rotating shaft 21, one end of which is fixed to the brush head 20. The drive assembly 3 includes a drive motor 30 and a plurality of eccentric mechanisms drivenly connected to the output end of the drive motor 30, each eccentric mechanism being drivenly connected to a rotating column.

[0044] Specifically, the width of the lower end of the rotating shaft 21 is greater than the width of the upper end of the rotating shaft 21. The lower end of the rotating shaft 21 is inserted into the brush head 20, which is made of flexible material. The lower end of the rotating shaft 21 and the brush head 20 are interference-fitted. The brush head 20 and the rotating shaft 21 are detachable from each other. The output end of the drive assembly 3 is connected to the upper end of the rotating shaft 21. The movement of the rotating shaft 21 drives the movement of the brush head 20. With this configuration, the brush head 20 can be removed from the rotating shaft 21, which is convenient for cleaning and maintenance of the brush head 20. If it is damaged, the brush head 20 can be replaced in time.

[0045] Furthermore, an eccentric mechanism is installed inside the housing 1. This eccentric mechanism connects the drive motor 30 and the rotating shaft 21. When the drive motor 30 outputs power, the rotating shaft 21, driven by the eccentric mechanism, can perform a reciprocating eccentric motion, causing the brush head 20 to move within a circular range. This configuration, compared to an embodiment where the brush head 20 rotates along the axis of the rotating shaft 21, further increases the cleaning range of the brush head 20, allowing for faster skin cleaning and thus improving the cleaning effect of the cleaning device. In other embodiments, the drive assembly 3 includes a reciprocating mechanism and a drive motor 30. The reciprocating mechanism connects the drive motor 30 and the rotating shaft 21, and the drive motor 30 can drive the rotating shaft 21 to perform reciprocating motion.

[0046] In some embodiments, the eccentric mechanism includes a driven gear 33, which has an eccentric hole 331. One end of the rotating shaft 21 is inserted into the eccentric hole 331. The drive assembly 3 includes a drive gear 31. The output end of the drive motor 30 is driven and connected to the drive gear 31. The driven gear 33 meshes with the drive gear 31. When the driven gear 33 rotates, it can drive the rotating shaft 21 to perform horizontal circular motion.

[0047] Specifically, the upper end of the rotating shaft 21 is inserted into the eccentric hole 331. The driving gear 31 and the driven gear 33 are rotatably mounted inside the housing 1. The drive assembly 3 also includes a reduction gear 32, which is sleeved on the output shaft of the drive motor 30. The reduction gear 32 meshes with the driving gear 31, and the driven gear 33 meshes with the driving gear 31. When the drive motor 30 outputs power, it drives the rotating shaft 21 to perform horizontal circular motion through the gear set. In this embodiment, the rotating shaft 21 performs a circular pendulum motion. This configuration achieves the eccentric motion of the rotating shaft 21, resulting in high gear transmission stability and reducing the likelihood of slippage, thereby ensuring the stable movement of the brush head 20. In other embodiments, the eccentric mechanism includes a cam block. The output shaft of the drive motor 30 is inserted into the cam block, which has an eccentric hole 331. The rotating shaft 21 is inserted into the eccentric hole 331.

[0048] In some embodiments, the cleaning brush assembly 2 and the eccentric mechanism are provided in two corresponding positions. The two driven gears 33 are respectively located on opposite sides of the driving gear 31. When the two driven gears 33 rotate, the distance between the two eccentric holes 331 first decreases and then increases.

[0049] Specifically, in this embodiment, there are two cleaning brush assemblies 2, and correspondingly two eccentric mechanisms, namely, two driven gears 33, two brush heads 20, and two rotating shafts 21. One driving gear 31 meshes with two driven gears 33, so that the two driven gears 33 rotate in the same direction. In the stationary state, the two eccentric holes 331 are located at the farthest ends. In the moving state, the distance between the two eccentric holes 331 first decreases and then increases, repeating this cycle. This allows the two rotating shafts 21 to move in opposite directions, meaning the two brush heads 20 will first approach each other and then move away, simulating the rubbing motion of a human hand cleaning the face. This design allows for efficient cleaning of the area when the two brush heads 20 approach each other, thereby improving the cleaning effect of the cleaning device and enhancing user experience and comfort. In other embodiments, the distance between the two eccentric holes 331 remains unchanged when the two driven gears 33 rotate.

[0050] In some embodiments, the cleaning brush assembly 2 further includes a fixed disk 23 and a movable member 22 fixed on the rotating shaft 21. The fixed disk 23 is installed in the housing 1 and has a rotating cavity 233 inside. The rotating cavity 233 is adapted to the shape of the movable member 22. The movable member 22 is movably installed in the rotating cavity 233, and both ends of the rotating shaft 21 pass through the rotating cavity 233.

[0051] Specifically, through holes are provided at both the upper and lower ends of the rotating cavity 233. The width of the through holes is smaller than the diameter of the movable part 22. Before assembling the fixed plate 23, the movable part 22 is installed in the rotating cavity 233. In this way, when the rotating shaft 21 moves, the movable part 22 will not disengage from the rotating cavity 233. Driven by the driven gear 33 and limited by the rotating cavity 233, the rotating shaft 21 can move stably and smoothly. This arrangement realizes the horizontal circular motion of the rotating shaft 21 and can increase the motion stability of the rotating shaft 21. In some other embodiments, the cleaning brush assembly 2 includes a fixed plate 23. A protruding post is provided at the center of the fixed plate 23. An hourglass-shaped movable hole is provided in the protruding post. The rotating shaft 21 is inserted into the movable hole. The inner wall of the movable hole can limit the rotation shaft 21 to realize the horizontal conical motion of the rotating shaft 21.

[0052] Furthermore, the movable part 22 is spherical, and the axis of the rotating shaft 21 intersects the center line of the movable part 22, with the angle of intersection being less than 1 degree.

[0053] Specifically, the angle between the axis of the rotating shaft 21 and the center line of the movable member 22 is angle α, which is an acute angle. The movable member 22 is configured as a sphere, and a rotating cavity 233 is provided in the fixed disk 23. The rotating cavity 233 is configured as a spherical cavity. The movable member 22 can rotate in the rotating cavity 233. While the movable member 22 rotates, it drives the rotating shaft 21 to swing. Because the rotating shaft 21 is inclined relative to the movable member 22, the trajectory of the rotating shaft 21 when swinging is circular. That is, with the movable member 22 as the reference point, the upper and lower parts of the rotating shaft 21 both make circular motion in the horizontal plane. In this embodiment, the motion of the rotating shaft 21 is similar to that of a conical pendulum model.

[0054] Furthermore, the fixed plate 23 includes a bottom shell 232 and a cover 231. The cover 231 covers the bottom shell 232 to form a rotating cavity 233. Opening the cover 231 allows the movable part 22 to be placed into the rotating cavity 233. Closing the cover 231 again can limit the movable part 22 within the rotating cavity 233. The cleaning brush assembly 2 also includes a sealing sleeve 27. The sealing sleeve 27 is fitted onto the fixed plate 23, and the lower end of the rotating shaft 21 is inserted into the protrusion at the bottom of the sealing sleeve 27 before being inserted into the brush head 20. The protrusion at the lower end of the sealing sleeve 27 can deform. When the rotating shaft 21 makes a conical pendulum motion, the protrusion can bend and move accordingly. The sealing sleeve 27 can isolate the brush head 20 from the rotating shaft 21, the fixed plate 23, and the internal structure of the housing 1. This arrangement can ensure that water stains, dirt, and other impurities do not enter the housing 1, thereby protecting other structures inside the housing 1.

[0055] In some embodiments, the cleaning device further includes a mounting base 4, which is installed inside the housing 1. The drive motor 30 is fixed to the mounting base 4, and both the drive gear 31 and the driven gear 33 are rotatably mounted on the mounting base 4.

[0056] Specifically, the output shaft of the drive motor 30 passes through the reduction gear 32 and is inserted into the mounting base 4. Both the driving gear 31 and the driven gear 33 are rotatably mounted on the mounting base 4. This arrangement allows for the assembly of multiple gears by first mounting them on the mounting base 4 and then installing them into the housing 1, facilitating assembly. In other embodiments, the housing 1 is provided with multiple ribs, with the driving gear 31 and the driven gear 33 each mounted on one rib, and the drive motor 30 mounted on another rib.

[0057] In some embodiments, the cleaning brush assembly 2 includes a phototherapy mechanism mounted on the brush head 20. The brush head 20 has a light-transmitting portion 28, which is disposed on the same side as the bristles 29 of the brush head 20 and is disposed away from the bristles 29. The phototherapy mechanism transmits light through the light-transmitting portion 28.

[0058] Specifically, the brush head 20 has bristles 29 and a light-transmitting part 28 on the side away from the housing 1. A phototherapy mechanism is located inside the brush head 20. The light emitted by the phototherapy mechanism can be projected onto the outside of the brush head 20 through the light-transmitting part 28, and the light-transmitting part 28 is not blocked by the bristles 29. Thus, during the cleaning process, phototherapy can be applied to the skin simultaneously. Phototherapy assists the brush head 20 in deeply cleaning the skin and repairing damaged areas. This design enhances the functionality of the cleaning device and improves the user experience. In other embodiments, the cleaning device includes a phototherapy mechanism located inside the housing 1, with a light-transmitting hole at the bottom of the housing 1 for the light from the phototherapy mechanism to pass through.

[0059] In some embodiments, the light-transmitting portion 28 is arranged in a ring shape, and in the radial direction, brush bristles 29 are provided on both the inner and outer sides of the light-transmitting portion 28. The outer brush bristles 29 are distributed in a ring shape, and the inner brush bristles 29 are distributed in a polygon shape.

[0060] Specifically, the bristles 29 on the inner side of the light-transmitting portion 28 can be distributed in a circular, triangular, rectangular, rhomboid, or polygonal shape. In this embodiment, clusters of bristles 29 are provided on the inner side of the light-transmitting portion 28, with multiple bristles 29 distributed in a circular pattern. A ring of bristles 29 is distributed on the outer side of the light-transmitting portion 28. This arrangement allows for a greater distribution of bristles 29 within the circular area, increasing the cleaning effect. The phototherapy structure can concentrate light emission in one area, thus enhancing targeted phototherapy for a specific area. In other embodiments, the bristles 29 are disposed on the light-transmitting portion 28.

[0061] In some embodiments, the brush head 20 is provided with a fixing groove 24 for accommodating a phototherapy mechanism. The phototherapy mechanism includes a lamp plate 25 and lamp beads 26 disposed on the lamp plate 25. The lamp beads 26 are disposed corresponding to the opening of the fixing groove 24. The width of the opening of the fixing groove 24 is less than the maximum width of the fixing groove 24. The light-transmitting part 28 is a light-transmitting cover that covers the opening of the fixing groove 24. The light-transmitting part 28 includes a limiting part 281 and a mating part 282. The limiting part 281 is located inside the fixing groove 24 and abuts against the groove wall of the fixing groove 24 with the opening. The mating part 282 is adapted to fit into the opening.

[0062] Specifically, the fixing groove 24 on the brush head 20 is located at the bottom of the brush head 20, and the fixing groove 24 has a groove structure that is wide inside and narrow at the opening. The lamp plate 25 is installed in the fixing groove 24, and the lamp bead 26 is exposed through the opening of the fixing groove 24. The light-transmitting part 28 is configured as a light-transmitting cover structure. The light-transmitting cover is fixed to the opening of the fixing groove 24. The opening of the fixing groove 24 is smaller than the overall width of the light-transmitting cover. Since the brush head 20 is made of a material with a certain degree of elasticity, the opening of the fixing groove 24 can be pried open to insert the light-transmitting cover. The interior of the fixing groove 24 has enough space to accommodate the light-transmitting cover.

[0063] Furthermore, the light-transmitting cover is divided into a limiting part 281 and a mating part 282, which are two connected parts. The limiting part 281 extends into the fixing groove 24 and abuts against the groove wall of the fixing groove 24 to prevent the light-transmitting cover from moving vertically along the groove opening, thereby fixing the light-transmitting cover to the fixing groove 24. The mating part 282 is precisely inserted into the groove opening of the fixing groove 24, thereby completely sealing the groove opening of the fixing groove 24. During assembly, the lamp plate 25 can be installed in the light-transmitting cover first and then both can be installed into the fixing groove 24 together, or the lamp plate 25 can be fixed to the fixing groove 24 first and then the light-transmitting cover can be installed. This arrangement can increase the installation stability between the light-transmitting cover and the fixing groove 24 and prevent the light-transmitting cover from detaching from the brush head 20 during use. In some other embodiments, the light panel 25 is located inside the brush head 20, that is, the light panel 25 is fixed inside the brush head 20 by injection molding. The LED beads 26 are arranged on the same side as the brush bristles 29. The side of the brush head 20 with the brush bristles is made of a semi-transparent material, and the light from the LED beads 26 can be projected outward from the transparent part.

[0064] In some embodiments, the light-transmitting portion 28 is provided with a mounting groove 283, which is recessed in the mating portion 282, and the opening of the mounting groove 283 is disposed facing the lamp plate 25. The lamp bead 26 is located inside the mounting groove 283, and the lamp plate 25 is located outside the mounting groove 283 and is held by the limiting portion 281 and the wall of the fixing groove 24.

[0065] Specifically, the light-transmitting cover has a mounting groove 283, which is used to avoid the placement of the LED beads 26 on the light panel 25, preventing the LED beads 26 from being crushed by the light-transmitting cover. The edge of the light panel 25 is abutted by the limiting part 281 of the light-transmitting cover, and the limiting part 281 presses the light panel 25 against the bottom wall of the fixing groove 24. This arrangement can ensure the service life of the LED beads 26, prevent the LED beads 26 from being crushed, and allow the mating part 282 to be made into a structure with high transparency, thereby improving the light transmission effect.

[0066] Furthermore, the shape of the lamp panel 25 is adapted to the brush head 20 to be set as a ring, and multiple lamp beads 26 are evenly spaced on the ring-shaped lamp panel 25.

[0067] In some embodiments, the cleaning device further includes a button sleeve 5 fitted over the housing 1. The housing 1 contains a button module 11 and a charging module 10. A charging port is provided at the top of the housing 1, through which the charging module 10 is exposed. The housing 1 has multiple pressing parts corresponding to the button module 11. The button sleeve 5 has multiple button protrusions 52, which are arranged one-to-one with the pressing parts. The function and speed of the cleaning device can be changed by the button protrusions 52. The button sleeve 5 also has a flexible plug 51, which is inserted into the charging port to prevent water and dust from entering the charging port.
