Meanwhile, the first motor 41 works to drive the transmission rod 50 to rotate in the forward direction, the first pushing piece 62 can push the corresponding end of the sleeve body 11 to enable the transmission part 16 to be meshed with the threaded section 51, in the meshed state, the sleeve body 11 can extend outwards along with the rotation of the transmission rod 50, and in the extending process of the sleeve body 11, the boss 15 slides along the sliding groove 71, which is shown in fig. 10; after the sleeve body 11 is stretched in place, the boss 15 can be separated from the chute 71 to enter the annular groove 74 and extrude the second elastic member 81, the transmission part 16 and the transmission rod 50 are still in a meshed state, the transmission rod 50 can drive the sleeve body 11 to rotate, and the bathing part 12 also synchronously rotates, so that the bathing action of moving up and down and rotating a user is realized, which is shown in fig. 11.

When the user closes the bath, the second motor is controlled to be closed, the screw rod 31 stops rotating, and the sliding seat 20 stops moving. Meanwhile, the first motor 41 is controlled to operate to drive the transmission rod 50 to rotate reversely, the second pushing piece 82 can push the boss 15 to enter the chute 71, the sleeve body 11 stops rotating, the sleeve body 11 can move inwards and retract along with the rotation of the transmission rod 50 until the transmission part 16 is positioned on the smooth section 52 of the transmission rod 50 and extrudes the first elastic member 61, the transmission part 16 is disengaged from the transmission rod 50, and the first motor 41 is controlled to be turned off, which is shown in fig. 8, 9 and 12.

According to the rubbing device, the rubbing mechanism 10 is arranged to be telescopic, when the rubbing device works, the rubbing mechanism 10 is controlled to move up and down and extend out, when the rubbing device extends out in place, the rubbing mechanism 10 is rotated to achieve rubbing, when the rubbing device does not work, the rubbing mechanism 10 is controlled to retract so as to reduce the size, and the user experience is improved.

The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using this concept shall fall within the scope of the present invention.
