More and more automated devices have entered our lives, making our lives more convenient and comfortable. At the same time, our pace of life is getting faster and faster, and our fatigue level is getting higher and higher. In order to relieve fatigue, many massage equipment has become people’s daily needs, and more and more massage equipment has appeared in people’s lives.

[0003] At present, bath scrubbing machines are widely used in the fields of bathroom and massage. Traditional bath scrubbing machines on the market still have many shortcomings. Existing bath scrubbing machines generally adopt a small handheld structure design. Since the small handheld bath scrubbing machine has a certain weight, it not only needs to be pushed manually to roll the bath scrubbing roller when in use, but also needs to be manually controlled in direction and strength. This bath scrubbing method is not only inefficient but also time-consuming and labor-intensive, and cannot meet the needs of users.

[0004] There are also some bath scrubbing machines on the market that use a wall-mounted fixed structure design. The bath scrubbing roller can only be rolled by the up and down movement of the human body to achieve the purpose of scrubbing, and the bath scrubbing efficiency is low. Once the position of this type of bath scrubbing machine is fixed, it cannot be adjusted. At the same time, the human body needs to move to achieve the scrubbing function. It cannot meet the needs of users of various body shapes, affects user pleasure, and has poor practicality.

[0005] Therefore, a back-worn automatic bath scrubbing machine has emerged, which may include a strap, a housing, a switch, a bath scrubbing head, a vertical screw motor, a horizontal screw motor, and a Z-axis screw motor. The bath scrubbing head is connected to the end of the Z-axis screw motor, the vertical screw motor drives the bath scrubbing head seat to move up and down, the horizontal screw motor drives the bath scrubbing head to move left and right, and the Z-axis screw motor drives the bath scrubbing head to move forward and backward. This structure is easy to carry and can be used to move back and forth on the concave and convex shapes of the back of the human body, and scrub well. However, this structure needs to be driven by multiple screw motor structures, which is complex in structure, high in cost, and heavy in overall weight, causing a heavy load on the shoulders and affecting comfort.

That is, the hydraulic drive mechanism 20 is used to convert hydraulic power into mechanical energy output. Specifically, the hydraulic drive mechanism 20 includes two waterway components 22, an impeller 23 and a rotating member 24. The two waterway components 22 are arranged at intervals, one as a water inlet waterway and the other as a water outlet waterway. The rotating member 24 is rotatably connected between the two waterway components 22. The rotating member 24 is a hollow structure, which can connect the two waterway components 22 to form a connecting waterway therewith, that is, water can enter from one of the waterway components 22, enter the other waterway component 22 through the rotating member 24, and then flow out.

The driving gear 21 is fixed outside the rotating member 24, that is, when the impeller 23 rotates, it can drive the rotating member 24 and the driving gear 21 to rotate synchronously.

[0049] Furthermore, the water circuit assembly 22 includes a tube body 25 and a joint 26, one end of the tube body 25 is fixedly connected to the joint 26, and the other end of the tube body 25 can be fixedly connected to the housing 10, and the housing 10 is correspondingly provided with an interface 16, and the interface 16 is connected to the other end of the tube body 25.

[0050] Preferably, a cavity is provided in the joint 26, and the impeller 23 is rotatably disposed in the joint 26 of one of the waterway components 22. The impeller 23 is provided with a plurality of blades 23b, and an angle is formed between the blades 23b and the water inlet hole 26a of the joint 26, that is, the water inlet hole 26a can be an inclined hole, and the water flow of the pipe body 25 is projected from the water inlet hole 26a to the blades 23b at a certain angle, driving the impeller 23 to rotate. The rotation direction of the impeller 23 can be determined by the angle of the water inlet hole 26a.

[0051] The transmission mechanism 30 is provided with a transmission gear set 31 and a driven member 32, and the driven member 32 is fixed coaxially with the transmission gear set 31. The transmission gear set 31 and the driving gear 21 are in transmission cooperation to intermittently drive the driven member 32 to rotate, that is, when the driving gear 21 rotates, there are two states between it and the transmission gear set 31, namely, transmission or non-transmission, wherein non-transmission means that there is no transmission between the two.

[0052] Specifically, the outer periphery of the driving gear 21 is provided with a first tooth portion 21a and a smooth portion 21b, the first tooth portion 21a is at least two teeth, and the outer periphery of the driving gear 21 except the first tooth portion 21a is not provided with a tooth portion, that is, the smooth portion 21b. The driving gear 21 is provided with fewer teeth to play the role of gap transmission, and can also reduce the rotation speed of the transmission gear set 31. The transmission gear set 31 includes a transmission gear 33 and a transmission shaft 34. The transmission gear 33 is fixedly sleeved outside the transmission shaft 34, and the transmission gear 33 is fixed to the transmission shaft 34 by a pin. The outer periphery of the transmission gear 33 is provided with a second tooth portion 33a, that is, the outer periphery of the transmission gear 33 is entirely provided with the second tooth portion 33a. When the driving gear 21 rotates until the first tooth portion 21a is meshed with the second tooth portion 33a, that is, the driving gear 21 and the transmission gear 33 are in transmission cooperation, the transmission gear 33 can be driven to rotate in the positive direction. When the driving gear 21 rotates until the smooth portion 21b is opposite to the second tooth portion 33a, that is, there is no transmission between the driving gear 21 and the transmission gear 33, and the transmission gear 33 is not driven to rotate by the driving gear 21.

[0053] The main body 14 of the housing 10 is provided with a guide hole 11, and the movable plate 40 is movably arranged on one side of the main body 14, that is, the extension direction of the guide hole 11 is the same as the movement direction of the movable plate 40. In actual application, the guide hole 11 can be arranged to extend along the length direction of the main body 14, but is not limited thereto. The movable plate 40 is located outside the main body 14, and its outer side, i.e., the side facing away from the main body 14, serves as a bathing surface 43, and its inner side, i.e., the side opposite to the main body 14, is provided with a pushing component. The pushing component passes through the guide hole 11 and abuts against or is connected to the follower 32.

[0054] Further, the follower 32 is a cam or is provided with a protrusion, and the cam or protrusion is in contact with or connected to the pusher, preferably in contact with each other, so that when the follower 32 rotates, it can push the movable plate 40 to move. The first elastic member 50 is arranged between the housing 10 and the movable plate 40 to drive the movable plate 40 to return to its original position. In actual application, the first elastic member 50 can also be arranged between the pushing component and the housing 10.

[0055] Specifically, there may be multiple pushing components on the movable plate 40 , which are divided into a first pushing component 40 a and a second pushing component 40 b . The first pushing component 40 a is used to cooperate with the follower 32 , and the second pushing component 40 b can be used to cooperate with the first elastic component 50 .

[0056] The movable plate 40 may be provided with at least one first push assembly 40a, preferably two first push assemblies 40a and distributed on the left and right sides, and the transmission mechanism 30 is correspondingly provided with at least one follower 32, preferably two followers 32, respectively located near the two ends of the transmission shaft 34. The first push assembly 40a includes a push portion 41 and two rollers 42, the push portion 41 is fixed to the movable plate 40 and is in contact with or connected to the corresponding follower 32, and the two rollers 42 are rotatably arranged on both sides of the push portion 41. The housing 10 is also correspondingly provided with at least one track group, which should be selected as two track groups distributed on the left and right sides, each track group is provided with two tracks 12 to slide with the corresponding rollers 42, and the two tracks 12 are arranged in parallel on both sides of the guide hole 11. When the follower 32 rotates forward, its convex part can push the push portion 41, so that the roller 42 rolls along the track 12, and the movable plate 40 moves forward along the guide hole 11. When the follower 32 stops, the movable plate also stops, and the first elastic member 50 is compressed at this time.

[0057] The movable plate 40 is also provided with at least one second pushing assembly 40b, preferably two second pushing assemblies 40b and distributed on the left and right. The second pushing assembly 40b includes a pushing portion 41 and two rollers 42, the pushing portion 41 is fixed to the movable plate 40, and the two rollers 42 are rotatably arranged on both sides of the pushing portion 41. The housing 10 is correspondingly provided with a baffle 17 and at least one track group, the track group is provided with two tracks 12 to slide with the corresponding rollers 42, and the two tracks 12 are arranged in parallel on both sides of the guide hole 11. The baffle 17 can be one, including two first elastic members 50, which are respectively arranged between the corresponding pushing portion 41 and the baffle 17. When the driving gear 21 and the transmission gear 33 are non-transmitting, that is, when the transmission gear 33 and the driven member 32 are not driven to rotate by the driving gear 21, the first elastic member 50 returns to its position, driving the movable plate 40 to return to its position along the guide hole 11.

[0058] In practical applications, two track groups can be set on the shell 10, distributed left and right, and the two first pushing components 40a and the two second pushing components 40b can be distributed up and down, and their rollers 42 can be slidably matched with the track 12 of the track group, and the baffle 17 can be located below the track group.

[0059] Furthermore, in the present invention, the movable plate 40 is driven to move and return to its original position by the cooperation of the hydraulic driving mechanism 20 and the transmission mechanism 30 to realize the scrubbing. When the driving gear 21 and the transmission gear 33 are converted from the transmission state to the non-transmission state, it can also be configured to drive the transmission gear 33 to rotate in the opposite direction by a certain angle, so that the driven member 32 pushes the movable plate 40 to move in the opposite direction to realize vibration, thereby increasing the frequency of scrubbing.

[0060] Specifically, the transmission gear set 31 further includes a ratchet 35, a movable member 36 and a second elastic member 37. The ratchet 35 is sleeved outside the transmission shaft 34 and fixed to the housing 10. The ratchet 35 is provided with a plurality of circumferentially distributed one-way teeth 38. The movable member 36 can be axially slidably sleeved on the transmission shaft 34 and is circumferentially fixed thereto, that is, the movable member 36 can move axially along the transmission shaft 34, and the movable member 36 and the transmission shaft 34 can rotate coaxially. The movable member 36 is provided with a top tooth 36a on the side opposite to the one-way tooth 38, and the top tooth 36a is in transmission contact with the one-way tooth 38. The provision of the top tooth 36a can also ensure that when the driving gear 21 and the transmission gear 33 are in transmission cooperation, the movable member 36 and the transmission shaft 34 can only rotate in the positive direction. The second elastic member 37 is stretched between the transmission gear 33 and the movable member 36, which can drive the movable member 36 to move axially along the transmission shaft 34, ensuring that the top tooth 36a abuts against the one-way tooth 38.

[0061] Furthermore, each one-way tooth 38 is provided with an inclined surface 38a and a pushing surface 38b. The inclined surface 38a is located at one end of the pushing surface 38b, and the pushing surface 38b and the inclined surface 38a have an angle. Then, when the first tooth portion 21a is meshed with the second tooth portion 33a, that is, the driving gear 21 is in transmission cooperation with the transmission gear 33, the transmission gear 33 drives the movable member 36 and the driven member 32 to rotate forwardly so that the top tooth 36a slides forwardly 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 member 37 drives the movable member 36 to move axially and drives the top tooth 36a to slide reversely along the inclined surface 38a to the pushing surface 38b, and at the same time drives the transmission gear 33 and the driven member 32 to rotate in the opposite direction, and the driven member 32 pushes the pushing member so that the movable plate 40 moves and vibrates in the opposite direction. The inclined surface 38 a is inclined along the circumferential direction of the ratchet wheel 35 , and the vibration amplitude of the movable plate 40 is related to the length of the inclined surface 38 a . Therefore, the length of the inclined surface 38 a can be set as required.

[0062] The movable board 40 of the present invention includes a board body 45 and a bath scrubbing cover 43a. The board 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 penetrated through the limiting hole 13. The limiting portion 46 cooperates with the limiting hole 13 to limit the moving distance of the movable board 40, thereby preventing the movable board 40 from moving too far. The bath scrubbing cover 43a is sleeved outside the board body 45. The bath scrubbing cover 43a serves as a bath scrubbing surface 43. The bath scrubbing cover 43a is provided with evenly distributed soft hair or soft strips. The bath scrubbing cover 43a can be made of soft rubber material or other common materials used for bath scrubbing. The housing 10 of the present invention is configured as a fixed structure or a movable structure, which can be selected according to needs.

[0063] For example: See Fig.12 , Fig.13 At least one shoulder strap 47, preferably two shoulder straps 47, is connected to the side of the main body 14 opposite to the movable plate 40, so as to facilitate carrying the housing 10 on the back. A plurality of suction cups 48 are also provided on the side of the main body 14 opposite to the movable plate 40, through which the housing 10 is adsorbed on the back to prevent the housing 10 from moving relative to the back and affecting the scrubbing effect. The number and position of the suction cups 48 can be set according to the size and shape of the main body 14, and are not limited here. Preferably, there are four suction cups distributed near the four corners.

[0064] Based on this, the present invention can also propose a bath scrubbing device, including a circulating water supply device and at least one of the above-mentioned bath scrubbing devices, the hydraulic drive mechanism 20 is connected to the circulating water supply device, and the circulating water supply device provides the hydraulic drive mechanism 20 with a water flow with a certain water pressure.

[0065] Specifically, the circulating water supply device may include a circulating water circuit, a water tank and a pump body. The water inlet and outlet ends of the circulating water circuit are connected to the water tank. The pump body is connected to the circulating water circuit to pump the tank water into the circulating water circuit and then return it to the water tank. The two water circuit components 22 of each portable bathing device are respectively detachably connected and connected to the circulating water circuit.

[0066] The bath scrubbing device and equipment of the present invention can also be provided with a control valve on the water channel assembly 22 to control the on-off of the connecting water channel. The bath scrubbing working principle is as follows:

[0067] After the water flows into the hydraulic drive mechanism 20 from the circulating water supply device, the impeller 23 is driven to rotate, and the impeller 23 drives the rotating member 24 and the driving gear 21 to rotate, and the water flows back to the circulating water supply device; during the rotation of the driving gear 21, when the first tooth portion 21a is meshed with the second tooth portion 33a, that is, the driving gear 21 and the transmission gear 33 are in transmission cooperation, the driving gear 21 can drive the transmission gear 33 to rotate in the positive direction, and the movable member 36 also rotates in the positive direction, and its top tooth 36a slides in the positive direction along the inclined surface 38a of the one-way tooth 38, then the driven member 32 also rotates in the positive direction, which can push the pushing portion 41 of the pushing assembly to move downward along the guide hole 11, drive the movable plate 40 to move in the positive direction (that is, move downward), and the roller 42 rolls along the track 12, and the first elastic member 50 is compressed at this time.

[0068] When the driving gear 21 rotates to the point 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, and 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 move axially and drive the top tooth 36a to slide in the opposite direction along the inclined surface 38a. Due to the action of the inclined surface, the movable member 36 drives the transmission gear 33 and the driven member 32 to rotate in the opposite direction, so that the movable plate 40 moves in the opposite direction (i.e., moves upward) to achieve 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 component 40b to move upward, so that the movable plate 40 returns to its original position. This is a movement cycle of the movable plate 40, and this is repeated to achieve scrubbing.

[0069] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
