[0043] like Figure 3 As shown, the vertical tube 1 includes a base 101, a vertical tube cover 102, and a support tube 103. The base 101 is mounted on the bottom end of the support tube 103, and the vertical tube cover 102 is mounted on the top end of the support tube 103. The trapezoidal screw 202 of the longitudinal movable structure 2 is located in the inner cavity of the support tube 103. The upper end of the trapezoidal screw 202 is fixed to the vertical tube cover 102, and the lower end of the trapezoidal screw 202 is fixed to the base 101. The base 101 is used to fix the automatic bath scrubbing device; the vertical tube cover 102 is used to fix the trapezoidal screw 202; and the support tube 103 covers and protects the trapezoidal screw 202 and provides support.

[0044] like Figure 3 and 4As shown, the longitudinal moving structure 2 includes a longitudinal motor 201, a trapezoidal screw 202, a longitudinal screw nut 206, a screw bearing seat 203, a driven bevel gear 204 and a driving bevel gear 205. The longitudinal motor 201 is mounted on the top of the workbench base 7 and is located on the left side of the vertical tube 1. The workbench base 7 is mounted on the screw bearing seat 203, and the screw bearing seat 203 is sleeved on the longitudinal screw nut 206, and the longitudinal screw nut 206 is connected to the trapezoidal screw 202 through a thread.

The controller 6 controls the rotation of the dual-axis motor 502.

[0048] The motor waterproof frame 501 serves to fix the dual-axis motor 502 and provide waterproof protection for the dual-axis motor 502; the dual-axis motor 502 provides power for the bath towel transmission structure 3, and further provides lateral movement power for the bath towel 4; the second left transmission rod 503 allows the left shaft sleeve 505 to achieve circular motion; the second right transmission rod 504 allows the right shaft sleeve 506 to achieve circular motion; the left shaft sleeve 505 allows the left transmission rope 301 to be pulled forward and backward, and prevents the left transmission rope 301 from being entangled in the second left transmission rod 503; the right shaft sleeve 506 allows the right transmission rope 302 to be pulled forward and backward, and prevents the right transmission rope 302 from being entangled in the second right transmission rod 504.

[0049] like Figure 6 and 9 As shown, the bath towel transmission structure 3 includes a left transmission rope 301, a right transmission rope 302, a left swing arm 303, a right swing arm 304, a swing arm locking structure, a swing arm mounting base 305, a left bath towel holder 308, and a right bath towel holder 309. The swing arm locking structure includes a left locking button 306 and a right locking button 307. The swing arm mounting base 305 is mounted on the bottom of the workbench base 7. The left swing arm 303 is adjustably mounted on the swing arm mounting base 305 via the left locking button 306, and the right swing arm 304 is adjustably mounted on the swing arm mounting base 305 via the right locking button 307. The left and right swing arms 303 and 304 are arranged outwardly in a "V" shape. Both the left and right swing arms 303 and 304 are hollow structures, with universal fulcrums at both ends to reduce friction experienced by the left and right transmission ropes 301 and 302 during transmission. One end of the left transmission rope 301 is connected to the left sleeve 505 of the pull-rope power structure 5, while one end of the right transmission rope 302 is connected to the right sleeve 506 of the pull-rope power structure 5. The other end of the left transmission rope 301 passes through the left swing arm 303 and is connected to the left towel holder 308.

Both the left and right towel holders 308 and 309 are equipped with a wire groove 3082 and a locking ring 3081, which respectively secure the ends of the bath towel 4.

[0050] The left transmission rope 301 and the right transmission rope 302 play a transmission role; the angle between the left swing arm 303 and the right swing arm 304 can be adjusted, which is used to open the bath towel 4 and guide the left transmission rope 301 and the right transmission rope 302; the swing arm locking structure is used to adjust and lock the opening width of the left swing arm 303 and the right swing arm 304; the swing arm mounting seat 305 is used to install the left swing arm 303 and the right swing arm 304; the left bath towel fixing frame 308 and the right bath towel fixing frame 309 are used to clamp and straighten the two ends of the bath towel 4, and facilitate the replacement of the bath towel 4.

[0051] The working principle of the pull rope power structure 5 and the bath towel transmission structure 3 is as follows: the second left transmission rod 503 and the second right transmission rod 504 are driven by the double-shaft motor 502 to move in a circle, thereby driving the left shaft sleeve 505 to pull the left transmission rope 301 to reciprocating swing, and the right shaft sleeve 506 to pull the right transmission rope 302 to reciprocating swing; the left transmission rope 301 and the right transmission rope 302 are connected to the two ends of the bath towel to form a closed loop, so that the bath towel can swing left and right.

[0052] As shown in Figure 18 the two ends of the scrubbing bath towel 4 are provided with horizontal tension lines 402, and the upper and lower ends of the horizontal tension lines 402 are provided with lock buckles 401. The left bath towel fixing frame 308 and the right bath towel fixing frame 309 are provided with wire grooves 3082, and the upper and lower ends of the wire grooves 3082 are provided with lock rings 3081. The horizontal tension lines 402 are buckled in the wire grooves 3082, so that the two ends of the scrubbing bath towel 4 are connected with the left transmission rope 301 and the right transmission rope 302 respectively. The lock buckles 401 are connected with the lock rings 3081, which can further prevent the horizontal tension lines 402 from falling off the left bath towel fixing frame 308 and the right bath towel fixing frame 309.

[0053] The working process of the automatic scrubbing device is as follows:

[0054] Firstly, the user powers on the automatic scrubbing device, and adjusts the height of the horizontal swing arm workbench (different height parts of the body for scrubbing) and the scrubbing speed of the bath towel through the remote control or voice according to the user's body condition.

The right end of the rocker arm 523 slides laterally through the right rocker rail 515 and is connected to one end of the right transmission rope 302. The rope-pull motor 511 is controlled by a controller 6.

[0070] The pull-rod motor 511 provides power for the reciprocating lateral movement of the bath towel 4. The motor waterproof frame 501 protects the pull-rod motor 511 and provides waterproofing. The swing assembly primarily converts the rotational motion of the pull-rod motor 511 into lateral motion. The left and right swing member rails 514 and 515 guide the slide swing member 513. The first connecting rod 521 converts the rotational motion of the pull-rod motor 511 into circular motion at one end of the first connecting rod 521. The second connecting rod 522 converts its circular motion into lateral motion of the swing rod 523. The swing rod 523 pulls the left and right transmission ropes 301 and 302 through its own lateral motion.

[0074] 2. If Figure 13-17 As shown, the swing arm locking structure in this embodiment uses a swing arm adjustment motor 310, a left swing arm connecting rod 311, a right swing arm connecting rod 312, a first left transmission rod 313, a first right transmission rod 314, a swing arm screw 315 and a swing arm screw nut 316 to replace the left locking button 306 and the right locking button 307. The swing arm adjustment motor 310 is installed in the motor waterproof frame 501 of the pull rope power structure 5, directly below the dual-axis motor 502. The swing arm adjustment motor 310 is controlled by the controller 6. The swing arm screw 315 is connected to the rotating shaft of the swing arm adjustment motor 310, and the swing arm screw nut 316 is threadedly mounted on the swing arm screw 315. The left end of the swing arm screw nut 316 is connected to one end of the first left transmission rod 313, and the other end of the first left transmission rod 313 is connected to the left swing arm 303. The right end of the swing arm screw nut 316 is connected to one end of the first right transmission rod 314, the other end of which is connected to the right swing arm 304. A protruding shaft is provided at the top of the left swing arm 303 and connected to one end of the left swing arm connecting rod 311. The other end of the left swing arm connecting rod 311 is hinged to the swing arm mounting base 305. A protruding shaft is provided at the top of the right swing arm 304 and connected to one end of the left swing arm connecting rod 312. The other end of the right swing arm connecting rod 312 is hinged to the swing arm mounting base 305. This swing arm locking structure allows for automated adjustment of the angle between the left and right swing arms 303, 304.

[0075] The swing arm adjustment motor 310 provides power for adjusting the angle between the left swing arm 303 and the right swing arm 304; the left swing arm connecting rod 311 limits the opening angle of the left swing arm 303; the right swing arm connecting rod 312 limits the opening angle of the right swing arm 304; the first left transmission rod 313 changes the angle of the left swing arm 303 by its own tilt angle; the first right transmission rod 314 changes the angle of the right swing arm 304 by its own tilt angle; the cooperation of the swing arm screw 315 and the swing arm screw nut 316 realizes the conversion of the rotational motion of the swing arm adjustment motor 310 into linear motion.

[0076] The working principle of the swing arm locking structure is explained as follows: as the swing arm screw nut 316 moves, the first left transmission rod 313 and the first right transmission rod 314 respectively pull the left swing arm 303 and the right swing arm 304 to unfold to the outside, and the left swing arm connecting rod 311 and the right swing arm connecting rod 312 are mainly used to limit the unfolding of the left swing arm 303 and the right swing arm 304 to the outside.

[0077] The above specific implementation manner is a preferred embodiment of the present invention and does not limit the present invention. Any other changes or other equivalent replacement methods that do not deviate from the technical solution of the present invention are included in the protection scope of the present invention.
