Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

[0037] An embodiment of the present utility model provides a multi-brush head counter-rotating electric bathing machine. As shown in combination with Figure 1-11 the figure, it includes a housing 1, a rotating assembly 2 and a gear assembly 3. The rotating assembly 2 includes an inner brush head 21, an outer brush head 22 and a massage head 23. The gear assembly 3 includes a sun gear 31, a first planetary gear 32 and a second planetary gear 33. The inner brush head 21 is connected to the sun gear 31, the outer brush head 22 is connected to the first planetary gear 32, and the massage head 23 is connected to the second planetary gear 33. An internal gear ring 121 is provided on the housing 1. The first planetary gear 32 is simultaneously meshed and connected to the internal gear ring 121 and the sun gear 31, and the second planetary gear 33 is meshed and connected to the first planetary gear 32. When the sun gear 31 rotates forward, the sun gear 31 drives the first planetary gear 32 to rotate reversely, and the first planetary gear 32 drives the second planetary gear 33 to rotate forward, so that the inner brush head 21 and the massage head 23 rotate forward, and the outer brush head 22 rotates reversely.

[0038] As Figure 10 and 11 shown, the forward direction can be the clockwise direction or the counterclockwise direction, and the reverse direction is the direction opposite to the forward direction. As Figure 1Taking the direction shown as an example, in this embodiment, the sun gear 31 is placed at the central position of the internal gear ring 121. There is one sun gear 31, four first planetary gears 32 and four second planetary gears 33. The 4 first planetary gears 32 are evenly distributed in the up, down, left and right directions of the sun gear 31. The 4 second planetary gears 33 are evenly distributed among the 4 first planetary gears 32. One second planetary gear 33 is meshed and connected with two adjacent first planetary gears 32 at the same time, so as to make the transmission smoother, the structure more stable and compact, and increase the service life of the gears. In other embodiments, it can be set that among two adjacent first planetary gears 32, only one first planetary gear 32 is meshed and connected with the second planetary gear 33, and it can also drive the second planetary gear 33 to rotate.

[0039] A handle 16 is connected to the housing 1. The handle 16 is not only convenient to hold and use, but also facilitates the user to effectively clean the back that is not easy to reach.

[0040] As Figure 7 shown, in the multi-brush head rotating in opposite directions electric bathing machine of the present utility model, by arranging a plurality of brush heads distributed inside and outside and rotating in opposite directions, the force during the scrubbing process is uniform, it is not easy to deviate, and no external force intervention control is required, so as to improve the scrubbing efficiency, scrub cleanly without leaving dead corners, greatly improve the bathing experience, improve the bathing quality and efficiency, and at the same time, a rotatable massage head 23 is also arranged, which has a massage function.

[0041] A rotatable lower planetary carrier 6 is arranged inside the housing 1. The gear assembly 3 includes several axle shafts 34. The upper end of the axle shaft 34 is connected to the rotating assembly 2. Several mounting grooves 61 are arranged on the lower planetary carrier 6. The lower end of the axle shaft 34 is received in the mounting groove 61. The internal gear ring 121 is fixed. When the first planetary gear 32 rotates in the reverse direction, the lower planetary carrier 6 and the axle shaft 34 rotate in the forward direction together.

[0042] As Figure 3 shown, taking the direction shown as an example, in this embodiment, several axle shafts 34 are respectively connected to the sun gear 31, the first planetary gear 32 and the second planetary gear 33. The shape and position of the mounting groove 61 are adapted to the axle shaft 34. The mounting groove 61 located at the central position penetrates up and down, so that the axle shaft 34 connecting the sun gear 31 can be connected to the motor 42.

[0043] An upper planetary carrier 5 is arranged inside the housing 1. The upper planetary carrier 5 and the lower planetary carrier 6 are connected and rotate synchronously with the lower planetary carrier 6. Several through grooves 52 are arranged on the upper planetary carrier 5. The upper end of the axle shaft 34 passes through the through groove 52 and is connected to the rotating assembly 2.

[0044] As Figure 9As shown, in this embodiment, a connecting column 62 is provided on the lower planet carrier 6, and the upper planet carrier 5 and the connecting column 62 are connected by bolts. As Figure 3 shown, the sun gear 31, the first planet gear 32, and the second planet gear 33 are all limited between the upper planet carrier 5 and the lower planet carrier 6, so that the structure is more stable and not easy to move.

[0045] The multi-brush head rotating-in-opposite-directions electric bathing machine further includes a control assembly 4. The housing 1 includes an isolation part 12, a lower housing part 13, and a rotatable upper housing part 11. The isolation part 12 is provided between the upper housing part 11 and the lower housing part 13. The control assembly 4 is provided between the isolation part 12 and the lower housing part 13. The gear assembly 3 is provided between the upper housing part 11 and the isolation part 12. The rotating assembly 2 is provided above the upper housing part 11.

[0046] As Figure 5 shown, in this embodiment, the upper housing part 11 is provided with a downwardly protruding buckle 111, and the upper planet carrier 5 is provided with a card slot 51 adapted to the buckle 111. The upper housing part 11 and the upper planet carrier 5 are snap-fitted and positioned through the buckle 111 and the card slot 51. The upper housing part 11, the upper planet carrier 5, and the lower planet carrier 6 rotate synchronously. Since the position of the internal gear ring 121 is fixed, when the sun gear 31 rotates forward, the sun gear 31 drives the first planet gear 32 to rotate in the opposite direction. The first planet gear 32 moves circumferentially along the internal gear ring 121 and drives the upper housing part 11, the upper planet carrier 5, and the lower planet carrier 6 to rotate forward synchronously.

[0047] A plurality of bull's-eye bearings 7 are provided in the housing 1, and the balls on the bull's-eye bearings 7 are in contact connection with the lower end surface of the lower planet carrier 6.

[0048] As Figure 3 shown in the direction, in this embodiment, four bull's-eye bearings 7 are evenly distributed. The lower planet carrier 6 is provided with an upwardly protruding contact part 63. The contact part 63 is arc-shaped, and the balls on the bull's-eye bearings 7 are in contact with the contact part 63. As Figure 8 shown, the isolation part 12 is recessed with a fixing groove 124, and the lower part of the bull's-eye bearing 7 is installed in the fixing groove 124.

[0049] The bull's-eye bearings 7 are used to bear the pressure of the lower planet carrier 6. When taking a bath, the rotating assembly 2 contacts the skin and receives a pressing force. The rotating assembly 2 transmits the pressing force to the lower planet carrier 6 through the wheel shaft 34. The lower planet carrier 6 transmits the pressure to the bull's-eye bearings 7. The bull's-eye bearings 7 bear the pressure, thus avoiding the frictional collision between the lower planet carrier 6 and the isolation part 12, playing a shock-absorbing effect, and at the same time making the rotation of the gear assembly 3 easier, the gear assembly 3 will not be distorted, and is more durable.

[0050] A positioning ring 14 is provided inside the housing 1. A ring-shaped limiting portion 141 protrudes upward from the positioning ring 14. The limiting portion 141 is disposed above the lower planet carrier 6, and the edge of the lower planet carrier 6 is adapted to be in limiting contact with the limiting portion 141.

[0051] As Figure 3 shown in the direction, in this embodiment, the positioning ring 14 and the isolation portion 12 are connected by bolts. The limiting portion 141 cooperates with the bull's-eye bearing 7 to limit the lower planet carrier 6 from the upper and lower directions respectively, so as to make the structure more stable.

[0052] A plurality of massage balls 231 are distributed on the upper end surface of the massage head 23, and the massage balls 231 are adapted to be in contact with the human skin.

[0053] As Figure 1 shown, in this embodiment, three massage balls 231 are evenly distributed on one massage head 23. The massage balls 231 can be fixedly arranged on the massage head 23 or be rotatably connected to the massage head 23.

[0054] The control assembly 4 includes a control board 41, a motor 42, a battery 43 and a button 44. The motor 42 is connected to the sun gear 31, and the control board 41 is electrically connected to the motor 42, the battery 43 and the button 44 respectively.

[0055] As Figure 3 shown, in this embodiment, the motor 42 is a reduction motor 42. The control assembly 4 further includes an indicator light (not shown), and the indicator light is electrically connected to the control board 41. After the button 44 is pressed, the indicator light lights up to visually remind the customer that the bathing machine is running.

[0056] A positioning groove 122 is provided on the isolation portion 12, and a positioning post 131 is provided on the lower housing portion 13. The positioning groove 122 is adapted to be inserted and positioned with the positioning post 131.

[0057] As Figure 3 shown in the direction, in this embodiment, the positioning post 131 protrudes upward from the inner bottom wall of the lower housing portion 13, and the positioning groove 122 protrudes downward from the bottom wall of the isolation portion 12. The positioning groove 122 and the positioning post 131 are inserted and positioned to make the connection between the isolation portion 12 and the lower housing portion 13 more stable.

[0058] A first convex block 132 is provided at the upper end of the side wall of the lower housing portion 13, and a second convex block 123 adapted to abut and connect with the first convex block 132 is provided at the lower end of the edge of the isolation portion 12. When the first convex block 132 and the second convex block 123 abut against each other, the first convex block 132, the second convex block 123 and the side wall of the isolation portion 12 cooperate to form a mounting cavity, and a sealing ring 15 is mounted in the mounting cavity. The sealing ring 15 is used to seal the connection gap between the lower housing portion 13 and the isolation portion 12.

[0059] As Figure 4 shown, such a setting facilitates the installation between the lower housing portion 13 and the isolation portion 12. At the same time, the sealing ring 15 prevents water from entering and affecting the control component 4 provided between the lower housing portion 13 and the isolation portion 12.
