[0017] Please see Figures 1 to 5This utility model provides a shampoo chair, including a height-adjustable seat 1, on which a movable seat 2 is provided. A backrest 3 and a seat 4 are hinged to the movable seat 2. A first push-pull part 5 and a second push-pull part 6 are provided within the movable seat 2. The output end of the first push-pull part 5 is hinged to the backrest 3, and the output end of the second push-pull part 6 is hinged to the seat 4. The first push-pull part 5 and the second push-pull part 6 respectively drive the angle adjustment of the backrest 3 and the seat 4. The output end of the first push-pull part 5, hinged to the backrest 3, achieves tilt adjustment of the backrest 3 through telescopic movement. The output end of the second push-pull part 6, hinged to the seat 4, achieves pitch adjustment of the seat 4 through telescopic movement. The height-adjustable seat 1 drives the entire shampoo chair to rise and fall vertically to adjust the working height of the shampoo chair, facilitating sitting or reclining use. This structure allows the shampoo chair to flexibly adjust its posture according to the user's needs, improving user comfort.

[0018] Specifically, the seat part 4 is provided with a seat cushion 7, and the seat part 4 is provided with a groove 41 that matches the shape of the seat cushion 7. The seat cushion 7 is at least partially located in the groove 41. The top of the backrest 3 is provided with a pillow connecting plate 31, and a pillow pad 8 is provided on the pillow connecting plate 31. The pillow pad 8 is provided with a clamp part 81 that surrounds the pillow connecting plate 31, and a fastener 82 is provided on the clamp part 81. The seat cushion 7 is at least partially embedded in the groove 41 on the seat part 4 that matches its shape, forming a detachable positioning structure. When it is necessary to clean up the water, the operator can directly remove the seat cushion 7 from the groove 41 without the need for tools, which is simple to operate. After cleaning, the dried or replaced seat cushion 7 is re-embedded into the groove 41 to achieve quick reset and positioning. The backrest cushion 8 is initially positioned by its backrest connecting plate 31, which is secured by a clamp 81 on its back. The clamp 81 has a fastener 82, which allows adjustment of the clamp's opening and closing position. When water needs to be cleaned from the backrest cushion 8, the operator simply releases the fastener 82 to quickly remove the backrest cushion 8 from the backrest connecting plate 31. After cleaning or replacement, the backrest cushion 8 is reattached to the backrest connecting plate 31 and re-secured to the clamp 82 via the clamp 81, completing the installation. This method significantly improves the user experience, allowing water to be removed from the shampoo chair promptly.

[0019] like Figures 1 to 5As shown, the pillow connecting plate 31 is further provided with at least two positioning grooves 32, and the bottom of the pillow pad 8 is provided with a positioning protrusion 83 that cooperates with the positioning grooves 32. When installing the pillow pad 8, the operator aligns the positioning protrusion 83 at the bottom of the pillow pad 8 with the positioning groove 32 on the pillow connecting plate 31, and presses it slightly to make the positioning protrusion 83 embed into the positioning groove 32, thereby positioning the pillow pad 8 in the horizontal direction; then, the clamp part 81 surrounds the pillow connecting plate 31 and cooperates with the buckle 82 to complete the final fixation, forming a multi-point stable connection structure.

[0020] It should be noted that the buckle 82 is an existing buckle assembly such as a straight-insertion buckle, a press-type buckle, or a rotary buckle. The specific structure and working principle are existing technologies and will not be described in detail here.

[0021] like Figures 1 to 5 As shown, the bottom of the seat cushion 7 is further provided with a stop block 71, and the seat part 4 is provided with a stop groove 42 that matches the shape of the stop block 71. During installation, the seat cushion 7 is placed into the groove 41 of the seat part 4 from top to bottom, so that the stop block 71 on the bottom surface of the seat cushion 7 naturally falls into the corresponding stop groove 42, forming a "concave-convex" fit; the outer contour of the stop block 71 and the inner contour of the stop groove 42 form a surface-to-surface or line-to-surface fit in the X and Y horizontal directions, achieving instant positioning; when the user sits down and moves, the buttocks generate front-to-back and left-to-right horizontal shear forces on the seat cushion 7; this shear force is first transmitted to the stop block 71, and the stop block 71 and the side wall of the stop groove 42 form a direct force-bearing surface, converting part of the horizontal load into groove wall compressive stress, preventing the seat cushion 7 from slipping, and achieving the stopping effect.

[0022] like Figures 1 to 5As shown, further, the lifting seat 1 includes a support base 11 and a first cylinder 12. A first guide cylinder 13 is provided on the support base 11, and the first cylinder 12 is disposed inside the first guide cylinder 13. The fixed end of the first cylinder 12 is hinged to the support base 11, and the output end of the first cylinder 12 is hinged to the movable seat 2. A second guide cylinder 21 is provided around the movable seat 2. The second guide cylinder 21 is slidably connected to the first guide cylinder 13, and the first guide cylinder 13 is at least partially located inside the second guide cylinder 21. During operation, the first cylinder 12 is placed inside the first guide cylinder 13, and its fixed end... The cylinder is hinged to the support base 11, and the output end is hinged to the movable seat 2. The piston rod of the cylinder extends and retracts axially, directly pushing the movable seat 2 to move up and down in the Z direction. Since both ends of the cylinder are hinged, it can automatically compensate for the angular deviation caused by manufacturing errors or slight off-center loads, avoiding interference problems. A second guide cylinder 21 is coaxially arranged on the periphery of the movable seat 2. The second guide cylinder 21 is sleeved on the outside of the first guide cylinder 13, forming an "inner-outer" sliding pair, so that the shampoo chair can still maintain vertical up and down when subjected to horizontal thrust or eccentric load. In addition, after the two guide cylinders are sleeved together, the internal cylinder and hinge point are completely wrapped to prevent hair, water droplets, and shampoo from entering, improving the overall waterproof performance.

[0023] like Figures 1 to 5 As shown, the first push-pull part 5 further includes a second cylinder 51. The fixed end of the second cylinder 51 is hinged to the movable seat 2. The output end of the second cylinder 51 is provided with a first hinge arm 52. One end of the first hinge arm 52 is hinged to the output end of the second cylinder 51. The backrest 3 is provided with a hinge rod 33. The other end of the first hinge arm 52 is hinged to the hinge rod 33. The fixed end of the second cylinder 51 is hinged to the movable seat 2, and the output end is hinged to the first hinge arm 52, forming a first-level lever. The other end of the first hinge arm 52 is hinged to the hinge rod 33 on the backrest 3, forming a second-level lever. The piston rod of the second cylinder 51 extends and retracts, causing the first hinge arm 52 to swing, so that the hinge rod 33 causes the backrest 3 to rotate around its own axis 23 with the movable seat 2, thereby realizing the posture adjustment of the backrest 3.

[0024] like Figures 1 to 5As shown, further, the movable seat 2 is provided with a rotating seat 22, and the rotating seat 22 is provided with a rotating shaft 23; the back of the backrest 3 is rotatably connected to both sides of the rotating seat 22, and the bottom of the seat part 4 is hinged with two opposing second hinge arms 24, one end of the two second hinge arms 24 is connected to the rotating shaft 23, and the output end of the second push-pull part 6 is connected to the rotating shaft 23; in use, when the second cylinder 51 pushes or pulls the backrest 3, the backrest 3 rotates around the axis of the rotating seat 22 to adjust the posture of the backrest 3; when the third cylinder 61 pushes or pulls the seat part 4, the seat part 4 rotates around the rotating shaft 23 to adjust the posture of the seat part 4; in the above manner, the backrest 3 and the seat part 4 can be adjusted in a fan shape, and the angle between the backrest 3 and the seat part 4 can be adjusted according to the user's sitting posture, reclining posture, or other different postures.

[0025] like Figures 1 to 5 As shown, the second push-pull part 6 further includes a third cylinder 61. The fixed end of the third cylinder 61 is hinged to the movable seat 2. The output end of the third cylinder 61 is provided with a third hinge arm 62.

In use, the fixed end of the third cylinder 61 is hinged to the movable seat 2, and the output end is hinged to the first end of the third hinge arm 62, forming a first-stage swing guide rod mechanism. The tail end of the third hinge arm 62 is connected to the rotating shaft 23, converting the swing of the third hinge arm 62 into the rotational motion of the rotating shaft 23. The two ends of the rotating shaft 23 then drive the seat part 4 through the second hinge arm 24 to complete the seat tilt adjustment.

[0026] like Figures 1 to 5 As shown, the edge of the support base 11 is provided with multiple extension legs 14; by providing multiple extension legs 14, the contact area between the support base 11 and the ground is increased, thereby making the support base 11 more stable and preventing the shampoo chair from tipping over during use.

[0027] In summary, the seat cushion 7 is at least partially embedded in the fitting groove 41 of the seat part 4, forming a detachable positioning structure. When cleaning accumulated water, the operator can directly remove the seat cushion 7 from the groove 41 without tools, making the operation simple. After cleaning, the dried or replaced seat cushion 7 is re-embedded into the groove 41 to reset its position. The backrest cushion 8 is initially positioned by the backrest clamp part 81 surrounding the backrest connecting plate 31, and the clamp part 81 is equipped with a fastener 82 for adjustment. When cleaning accumulated water, the fastener 82 is released to quickly remove the backrest cushion 8. After cleaning or replacement, the backrest cushion 8 is put back on and fixed to the clamp part 81 and the fastener 82 to complete the installation. This method improves the user experience and allows water to be removed from the shampoo chair in a timely manner.
