[0023] In the description of the present invention, it should be noted that certain words indicating orientation or positional relationships are only for the purpose of facilitating the description of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0024] Please refer to Figure 1 and Figure 2 The present invention provides a manual bathing and back-scrubbing chair, which consists of an outer frame 1, a box body 5, a tilt adjustment mechanism, a bathing tray movement mechanism, a seat 16 and a seat connector 17. The outer frame 1 is provided with a plurality of suction cups 4 and is fixedly mounted on the wall by adsorption of the suction cups 4. The tilt adjustment mechanism consists of two sets of mutually cooperating slide rails 2 and sliders 3. The two sliders 3 are respectively mounted on both sides of the box body 5 through hinges, and the two slide rails 2 are fixedly mounted on both sides of the surface of the outer frame 1. By moving the slider 3 on the slide rail 2, the box body 5 installed between the two sliders 3 can be tilted at different angles. A plurality of limiting holes are provided on the slide rail 2. By setting pins in the limiting holes at different positions, the slider 3 can be limited, thereby achieving the maintenance of the angle of the box body 5. As Figure 1 The figure is a schematic diagram of the structure of the embodiment of the present invention when the box is perpendicular to the ground. Figure 2The figure shows a schematic diagram of the structure of the embodiment of the present invention after the inclination angle of the box is adjusted to a certain angle. The seat 16 is installed under the box 5 through the seat connector 17. The seat 16 can be folded through the seat connector 17, and the legs of the seat 16 can be folded to achieve the effect of storage and unfolding. When needed, the user unfolds the seat 16 and flattens it, and supports the folded legs on the ground, and sits on the seat 16 to take a bath. When not in use, the user folds the legs of the seat 16 and turns the seat 16 to a position close to the box 5 through the seat connector 17 to achieve the storage of the seat 16. At this time, the box 5 automatically moves around the hinge on the slider 3 to a position close to the outer frame 1, and at the same time pulls the rocker 7 back upward to a position perpendicular to the ground, so as to achieve the purpose of saving space.

[0025] Please refer to Figure 4 and Figure 5 , the bathing tray motion mechanism has two sets, which are symmetrically arranged on the box body 5, and each set of bathing tray motion mechanism consists of a rocker 7, a bevel gear 8, a large pulley 9, a belt 10, a small pulley 11, a telescopic rod 12, a gear 13, a bathing tray mounting plate 14, a rack 15, and a bathing tray 6. In this embodiment, there are three bathing trays 6 in each set of bathing tray motion mechanism and they are installed on the bathing tray mounting plate 14 at intervals. The number of the gears 13 is the same as the number of the bathing trays 6 and they are coaxially fixed on the corresponding bathing trays 6. The gears 13 mesh with the racks 15, and the racks 15 are installed on the box body 5. The rocker 7 is connected to the bevel gear 8, and the bevel gear 8 is connected to the large pulley 9. The large pulley 9 and the small pulley 11 are driven by the belt 10. The small pulley 11 is connected to the telescopic rod 12, and the telescopic rod 12 is connected to the bathing tray mounting plate 14. The bevel gear 8, the large pulley 9 and the small pulley 11 are driven in sequence by shaking the rocker 7 up and down, and the telescopic rod 12 is driven to swing back and forth through the small pulley 11, thereby driving the bath scrubbing tray mounting plate 14 to make reciprocating linear motion. At the same time, the gear 13 and the rack 15 mesh with each other to cooperate in rotational motion and drive the bath scrubbing tray 6 connected to the gear 13 to make rotational motion to realize the bath scrubbing function.

[0026] See also Figure 5 The telescopic rod 12 is provided with a slide bar 18, a spring 19, a linear bearing 20 and a sleeve 21. The slide bar 18 and the sleeve 21 slide relative to each other through the linear bearing 20 to achieve the purpose of telescopic movement. The spring 19 is always in a compressed state to ensure that the telescopic rod 12 always outputs thrust outward. When the telescopic rod 12 swings back and forth, the thrust generated by the spring 19 can be used to press the gear 13 against the rack 15 to form a reliable meshing. At the same time, the telescopic movement of the telescopic rod 12 can compensate for the change in length of the telescopic rod 12 during the reciprocating swing.

[0027] Please refer to Figures 1 to 4 When in use, the user adjusts the angle of the box 5, unfolds the seat 16, and then sits on the seat 16 with his back against the box 5, and holds the rockers 7 on both sides of the box 5 with both hands to move up and down. The reciprocating swing of the rockers 7 drives the bevel gear 8 to make a reciprocating rotational motion, and the bevel gear 8 drives the large pulley 9 connected thereto and drives the small pulley 11 to synchronously make a reciprocating rotational motion through the belt 10. The small pulley 11 drives the telescopic rod 12 connected thereto to make a reciprocating swing, and the bath scrubbing tray mounting plate 14 connected to the other end of the telescopic rod 12 reciprocates up and down in a straight line with the reciprocating swing of the telescopic rod 12. At the same time, the gear 13 meshes with the rack 15 to rotate and drive the bath scrubbing tray 6 connected to the gear 13 to rotate, so as to realize the bath scrubbing function.

[0028] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
