In practical application, the housing 10 is provided with two track sets, which are distributed left and right, the two first pushing assemblies 40a and the two second pushing assemblies 40b can be distributed up and down, the rollers 42 thereof are in sliding fit with the tracks 12 of the track sets, and the baffle 17 can be located below the track sets.

Further, in the invention, the hydraulic driving mechanism 20 and the transmission mechanism 30 cooperate to drive the movable plate 40 to move and return to achieve the bath scrubbing. When the driving gear 21 and the transmission gear 33 are switched from the transmission state to the non-transmission state, the driving gear 33 can be driven to rotate reversely by a certain angle, so that the driven member 32 drives the movable plate 40 to move reversely to realize vibration, thereby increasing the bathing frequency.

Specifically, the transmission gear set 31 further includes a ratchet wheel 35, a movable member 36 and a second elastic member 37. The ratchet wheel 35 is sleeved outside the transmission shaft 34 and fixed with the housing 10, and a plurality of circumferentially distributed one-way teeth 38 are disposed on the ratchet wheel 35. The movable member 36 is axially slidably sleeved on the transmission shaft 34 and fixed circumferentially therewith, that is, the movable member 36 can axially move along the transmission shaft 34, and the movable member 36 and the transmission shaft 34 can coaxially rotate. The movable member 36 is provided with a top tooth 36a on a side opposite to the one-way tooth 38, the top tooth 36a is in transmission contact with the one-way tooth 38, and the top tooth 36a is arranged to ensure that the movable member 36 and the transmission shaft 34 can only rotate in the positive direction when the driving gear 21 and the transmission gear 33 are in transmission matching. The second elastic element 37 is stretched between the transmission gear 33 and the movable element 36, and can drive the movable element 36 to move axially along the transmission shaft 34, ensuring that the top tooth 36a abuts against the one-way tooth 38.

Further, each one-way tooth 38 is provided with a slope 38a and a pushing face 38 b. The bevel 38a is located at one end of the pushing surface 38b, and the pushing surface 38b is angled with respect to the bevel 38 a. When the first tooth portion 21a is engaged with the second tooth portion 33a, that is, the driving gear 21 is in driving engagement with the transmission gear 33, the transmission gear 33 drives the movable element 36 and the follower 32 to rotate in the forward direction, so that the top tooth 36a slides in the forward direction along the inclined surface 38a, and further drives the movable plate 40 to move. When the smooth portion 21b is opposite to the second tooth portion 33a, that is, the driving gear 21 and the transmission gear 33 are in a non-transmission state, the second elastic element 37 drives the movable element 36 to move axially to drive the top tooth 36a to slide reversely along the inclined surface 38a to the pushing surface 38b, and simultaneously drives the transmission gear 33 and the driven element 32 to rotate reversely, and the driven element 32 pushes the pushing element to make the movable plate 40 move reversely and vibrate. The inclined surface 38a is inclined along the circumferential direction of the ratchet 35, and the vibration amplitude of the movable plate 40 is related to the length of the inclined surface 38a, so that the length of the inclined surface 38a can be set as required.

The movable plate 40 of the present invention includes a plate body 45 and a scrubbing sleeve 43a, the plate body 45 is provided with a limiting portion 46, the housing 10 is correspondingly provided with a limiting hole 13, the limiting portion 46 is inserted into the limiting hole 13, the limiting portion 46 and the limiting hole 13 cooperate to limit the moving distance of the movable plate 40, so as to prevent the movable plate 40 from moving too far. The bathing cover 43a is sleeved outside the plate body 45, the bathing cover 43a is used as a bathing surface 43, soft hair or soft strips which are uniformly distributed are arranged on the bathing cover 43a, and the bathing cover 43a can be made of soft rubber materials or other common materials for bathing. The housing 10 of the present invention is configured to be fixed or movable, and can be selected according to the requirement.

For example: referring to fig. 12 and 13, at least one strap 47, preferably two straps 47, is further connected to the main body 14 on a side opposite to the movable plate 40, so as to facilitate carrying the housing 10 on the back. The main body 14 is further provided with a plurality of suckers 48 on one side relative to the movable plate 40, and the shell 10 is sucked on the back through the suckers 48, so that the shell 10 is prevented from moving relative to the back and the rubbing effect is prevented from being influenced. The number and position of the suction cups 48 may be set according to the size and shape of the main body 14, and are not limited herein, and are preferably four, and are distributed around four corners.

Based on the above, the invention also provides a rubbing device, which comprises a circulating water supply device and at least one rubbing device, wherein the hydraulic driving mechanism 20 is communicated with the circulating water supply device, and water flow with certain water pressure is provided for the hydraulic driving mechanism 20 through the circulating water supply device.

Specifically, the circulating water supply device may include a circulating water path, a water tank, and a pump body, wherein a water inlet end and a water outlet end of the circulating water path are communicated with the water tank, the pump body is connected with the circulating water path to pump water from the water tank to the circulating water path and then return the water to the water tank, and the two water path assemblies 22 of each portable bathing device are detachably connected and communicated with the circulating water path, respectively.

The bath rubbing device and the equipment of the invention can also be provided with a control valve on the waterway component 22 to control the on-off of the communicated waterway, and the bath rubbing working principle is as follows:

after entering the hydraulic driving mechanism 20 from the circulating water supply device, the water flow drives the impeller 23 to rotate, the impeller 23 drives the rotating part 24 and the driving gear 21 to rotate, and the water flow flows back to the circulating water supply device; in the rotation process of the driving gear 21, when the first tooth portion 21a is engaged with the second tooth portion 33a, that is, the driving gear 21 is in transmission fit with the transmission gear 33, the driving gear 21 can drive the transmission gear 33 to rotate in the forward direction, the movable member 36 also rotates in the forward direction, the top tooth 36a thereof slides in the forward direction along the inclined surface 38a of the one-way tooth 38, the driven member 32 also rotates in the forward direction, and the driven member can push the pushing portion 41 of the pushing assembly to move downward along the guide hole 11, so as to drive the movable plate 40 to move in the forward direction (that is, move downward), the roller 42 rolls along the track 12, and at this time, the first elastic member 50 is compressed.

When the driving gear 21 rotates to a position where the smooth portion 21b is opposite to the second tooth portion 33a, the transmission gear 33 is not driven to rotate by the driving gear 21, the top tooth 36a can stop at a certain position on the inclined surface 38a, at this time, the compressed second elastic member 37 can drive the movable member 36 to axially move to drive the top tooth 36a to reversely slide along the inclined surface 38a, and due to the inclined surface, the movable member 36 drives the transmission gear 33 and the driven member 32 to reversely rotate, so that the movable plate 40 reversely moves (i.e., moves upward) to realize vibration until the top tooth 36a abuts against the pushing surface 38b, and the movable member 36 and the transmission gear 33 stop rotating. Then, the first elastic member 50 acts to push the pushing portion 41 of the second pushing assembly 40b to move upward, so that the movable plate 40 returns, which is a movement cycle of the movable plate 40, and thus the bath rubbing is repeatedly performed.

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 the design concept should fall within the scope of infringing the present invention.
