The fully automatic back scrubbing machine in the present application is equipped with a back scrubbing module having multiple adaptive back scrubbing units. The brush head of each adaptive back scrubbing unit can automatically extend and retract according to the force exerted by the human body's back on the brush head while rotating. In this way, the brush on each brush head can fully contact the human body's back, and the end of each brush head can form an arc surface adapted to the shape of the human body's back according to the force exerted by the human body's back on the brush head, thereby being able to perform comprehensive and automatic cleaning of the human body's back.

[0031] In the above embodiment, if Figure 1 As shown, two vertical guide rods 201 are respectively provided on both sides of the box body 101, and a guide block 103 with a guide hole that cooperates with the guide rod 201 is provided on the box body 101. A driving block 104 with a threaded hole is also provided on the side wall of the box body 101, and a screw 202 is strung in the threaded hole of the driving block 104. A driving motor 204 connected to the screw 202 to drive the screw 202 to rotate is also installed on the bottom support plate 203. The driving motor 204 drives the screw 202 to rotate so that the box body 101 can move up and down along the guide rod 201, thereby making the box body 101 height adjustable as needed; of course, in the above embodiment, other driving devices such as racks, cams or linear motors can also be used to achieve height adjustment of the box body, which will not be repeated here.

[0032] In one embodiment of the present application, preferably, a driving wheel support seat 21 is fixed to the inner side of the front side plate 102, and a cylindrical cavity is provided in the middle of the driving wheel support seat 21; the cross section of the connecting rod 12 is a regular polygon, such as a triangular tetragon, a regular tetragon, a regular pentagon, a regular hexagon, etc., and a regular hexagon is preferably provided in this embodiment; a first connecting sleeve 22 is also provided between the driving wheel 20 and the connecting rod 12, and the middle part of the first connecting sleeve 22 is provided with a through hole whose cross section is adapted to the connecting rod 12, the driving wheel 20 is fixed on the first connecting sleeve 22 and is located at the end away from the front side plate 102, the first connecting sleeve 22 is installed in the driving wheel support seat 21 and can rotate relative to the driving wheel support seat 21; specifically, the driving wheel 20 is fixed to the front side plate 102 of the box body 101 through the driving wheel support seat 21 and the first connecting sleeve 22, and the driving wheel 20 can rotate relative to the first connecting sleeve 22 The front side plate 102 of the box body 101 rotates, and the distance between the driving wheel 20 and the front side plate 102 remains unchanged; the cross-section of the connecting rod 12 is a regular polygon and is inserted into the first connecting sleeve 22, so that when the driving wheel rotates 20, the connecting rod 12 can be driven to rotate through the first connecting sleeve 22, and the connecting rod 12 can slide axially in the first connecting sleeve 22; in this embodiment, by setting the connecting rod to have a regular polygonal cross-section and providing a through hole with a cross-section adapted to the connecting rod 12 in the middle of the first connecting sleeve 22, the connecting rod 12 can slide back and forth axially in the connecting sleeve 22, the structure is simple and the processing is convenient; of course, those skilled in the art can also adopt other similar structures, such as providing a slide groove in the inner cavity of the first connecting sleeve and providing a corresponding axial protrusion on the connecting rod, so that the connecting rod can slide axially in the first connecting sleeve and cannot rotate relative to the first connecting sleeve.

[0033] In one embodiment of the present application, preferably, a bearing 23 is further provided between the driving wheel support seat 21 and the first connecting sleeve 22 to reduce the rotational resistance of the connecting rod 12. Preferably, two bearings 23 are further provided between the driving wheel support seat 21 and the first connecting sleeve 22, thereby enabling the first connecting sleeve to rotate reliably in the driving wheel support seat 21 and ensuring that the central axis of the first connecting sleeve is perpendicular to the front side plate 102 of the box body 101.

[0034] In one embodiment of the present application, preferably, the driving wheel 20 is a pulley, and the pulley on the connecting rod 12 of each adaptive back-rubbing unit 10 is connected to the driving motor in the box through a belt. When the driving motor rotates, the pulley on the connecting rod 12 of each adaptive back-rubbing unit 10 can be driven to rotate through the belt, and the connecting rod 12 is driven by the pulley to drive the brush head 11 to rotate.

[0035] In another embodiment of the present application, preferably, the driving wheel 20 is a gear, and the gears on adjacent connecting rods 12 are meshed with each other. A driving motor for driving the gears to rotate is also provided in the housing 101. When the driving motor rotates, the gears on the connecting rods 12 of each adaptive back scrubbing unit 10 can be driven to rotate by the gears, and the connecting rods 12 are driven by the gears to drive the brush head 11 to rotate. Specifically, the gears on adjacent connecting rods 12 can be directly meshed or indirectly meshed through an intermediate transmission gear. When the gears on adjacent connecting rods 12 are directly meshed, the rotation directions of the adjacent connecting rods 12 are opposite. When the gears on adjacent connecting rods 12 are meshed through one or two intermediate gears, the rotation directions of the two adjacent connecting rods 12 are the same or opposite. The use of direct meshing or indirect meshing can be designed and selected according to parameters such as the size of the brush head, the diameter of the connecting rod, and the distance between adjacent connecting rods, which will not be repeated here. In one embodiment of the present application, Figure 5 、 Figure 6 As shown, the spacing between each connecting rod 12 in the vertical and horizontal directions is equal, the gears on adjacent connecting rods 12 are directly meshed, the gear on the connecting rod 12 located in the middle is meshed with the gears on the four adjacent connecting rods 12 above, below, left and right, and the rotation directions of adjacent connecting rods are opposite, thereby making the transmission between the connecting rods more reliable.

[0036] In another embodiment of the present application, preferably, a buffer spring 13 is further provided between the brush head 11 and the connecting rod 12, so that the brush head has a certain flexibility when rotating and axially extending with the connecting rod, thereby improving the comfort of the brush head when cleaning the human back.

[0037] In another embodiment of the present application, preferably, the brush head 11 is rectangular or elliptical. The use of rectangular or elliptical brush heads can make the cleaning ranges of each brush head intersect with each other, avoiding the occurrence of cleaning dead corners between adjacent brush heads, resulting in incomplete cleaning; specifically, the specific size and layout of the rectangular or elliptical brush head 11 can be designed and selected according to the distance between the connecting rods, so that adjacent brush heads can rotate at the same time and avoid interference when adjacent brush heads rotate. In one embodiment of the present application, the spacing between each connecting rod 12 in the vertical and horizontal directions is equal, and the length of the brush head 11 is greater than the distance between two adjacent connecting rods 12. Specifically, the design of the length and width of the brush head 11 needs to meet two adjustments: the cleaning areas of adjacent brush heads when rotating intersect with each other so that there are no cleaning dead corners between each brush head and there is no mutual interference when adjacent brush heads rotate. The process of calculating and designing the length, width and layout of the brush head according to the distance between the connecting rods will not be repeated here. In this embodiment, the driving wheel 20 is preferably a gear, thereby ensuring that the speed of each connecting rod 12 is the same. After long-term use, there will be no different speeds of the connecting rods due to wear of the belts and pulleys, and there will be no interference in the rotation of each brush head due to speed difference in the connecting rods caused by wear of the driving wheel.

[0038] In another embodiment of the present application, the adaptive telescopic device 30 preferably includes a piston cylinder 31 and a piston rod 32. The piston rod 32 can reciprocate within the piston cylinder 31. The connecting rod 12 is connected to the piston rod 32, thereby allowing the connecting rod 12 to reciprocate relative to the adaptive telescopic device 30 along the axial direction of the connecting rod 12. The piston cylinder 31 can be filled with hydraulic oil or compressible gas; preferably, the piston cylinder 31 is filled with compressed air; preferably, the piston cylinders 31 of each adaptive back scrubbing unit 30 are interconnected by a connecting pipe. When the back of a person contacts the brush head, the brush head under force contracts into the housing along with the connecting rod and the piston rod. The hydraulic oil, compressed gas, or compressed air in the corresponding piston cylinder is squeezed and flows to the adjacent piston cylinder, causing the brush head that has not yet contacted the back of the person to extend out of the housing. This allows each brush head to automatically adjust the length of the brush head extending out of the housing according to the force applied by the back of the person, so that the end of each brush head can form a curved surface that adapts to the shape of the back of the person according to the force applied by the back of the person.

[0039] In another embodiment of the present application, preferably, the adaptive telescopic device 30 includes a piston cylinder 31 and a piston rod 32. The piston rod 32 can reciprocate in the piston cylinder 31. A return spring 33 is also installed in the piston cylinder 32, so that the connecting rod 12 can reciprocate and retract along the axial direction of the connecting rod 12 relative to the adaptive telescopic device 30, so that each brush head can automatically adjust the length of the brush head extending out of the box according to the force exerted by the human back on the brush head, so that the end of each brush head can form an arc surface adapted to the shape of the back of the human body according to the force exerted by the human back on the brush head.

[0040] In another embodiment of the present application, preferably, a rotating connecting member 40 is further provided between the connecting rod 12 and the adaptive telescopic device 30, and the rotating connecting member 40 includes a connecting bearing 41 and a second connecting sleeve 42. The inner ring of the connecting bearing 41 is fixed to the end of the connecting rod 12, and the outer ring of the connecting bearing 41 is fixed in the second connecting sleeve 42. The adaptive telescopic device 30 is connected to the second connecting sleeve 42. Specifically, the piston rod 32 of the adaptive telescopic device 30 is connected to the second connecting sleeve 42, so that the piston rod 32 does not rotate when the connecting rod 12 rotates, that is, the piston rod can move axially with the connecting rod but does not rotate with the connecting rod.

[0041] In another embodiment of the present application, preferably, a plurality of nozzles 105 for spraying bath liquid, bath salt, or bath milk are further provided on the front side panel 102. Specifically, a liquid supply pipe connected to the nozzle 105 is provided in the box body 101, and a liquid storage device is provided inside or outside the box body. Thus, the brush head rotates to clean the back of the human body and spray bath products onto the back of the human body according to needs or program settings, thereby improving the comfort of users when using the fully automatic bath scrubbing machine.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
