Preferably, the shower arm main body 111 can move within the range of 0° to 180° of the angle between its length direction and the ground vertical direction. When the shower arm main body 111 is substantially parallel to the ground, its water spraying range can cover the whole body of the user; when the shower arm main body 111 is substantially perpendicular to the ground, it can reduce the occupancy of the bathroom space.

[0031] Preferably, as Figure 5 , Figure 7As shown in the figure, the cleaning unit 200 includes a multi-functional shower head 210 that can be suspended on the bathing chair 500, which has the functions of water spraying, foaming, and scrubbing. Specifically, the multi-functional shower head 210 includes a shower head housing 211, a shower head waterproof housing 212, and a shower head front cover 213. The shower head housing 211 is the main structure of the multi-functional shower head 210, which is a boxed structure with an open top and bottom. Among them, the top of the shower head housing 211 is blocked by the shower head front cover 213, and the bottom of the shower head housing 211 is blocked by the shower head waterproof housing 212. A number of shower nozzles 214 are provided in the area near the edge of the shower head front cover 213, and the shower water entering from the side wall of the shower head housing 211 can be sprayed out from the shower nozzles 214. At least two scrubbing discs 215 are arranged in the middle area of the shower head front cover 213. A turntable with grooves is equipped below the scrubbing discs 215. By using the grooves, users can replace the scrubbing discs 215 with different surface unevenness according to actual needs, so as to change the friction force during scrubbing. The turntable can be connected to the output shaft of a stepping motor arranged in the shower head housing 211, so that the scrubbing discs 215 can rotate driven by the stepping motor. An independent water isolation space is designed inside the shower head housing 211 to separate it from the shower water, effectively ensuring the safety of the stepping motor and its related circuits. Users can hold the multi-functional shower head 210 and use the rotating scrubbing discs 215 to automatically scrub different body parts, solving the problem of incomplete scrubbing caused by insufficient strength. The scrubbing discs 215 can be made of soft rubber or sponge, which can well fit the user's skin while ensuring the safety of the use process, making the cleaning more efficient and thorough.

[0032] Preferably, as Figure 5 shown, the shower head waterproof housing 212 can be selected as an airtight box body with the same top surface area as the bottom surface area of the shower head housing 211. The inside of the shower head waterproof housing 212 is hollow and can be used to install a battery box for supplying power to the stepping motor and a control board for controlling the start, stop, and rotation speed of the stepping motor. An air outlet is provided at the center of the shower head front cover 213 for releasing foam. Three switches are arranged on the side wall of the shower head waterproof housing 212 or the shower head housing 211, which are respectively used to realize the water spraying, foaming, and scrubbing functions of the multi-functional shower head 210. According to an optional implementation manner, the switch for realizing the scrubbing function of the multi-functional shower head 210 can be electrically connected to the control board arranged in the shower head waterproof housing 212, so that the pressing or not of the switch can be associated with the on-off of the circuit of the control board, thereby realizing the start and stop of the scrubbing discs 215. The design of the switches for realizing the water spraying and foaming functions of the multi-functional shower head 210 and their related components can refer to the prior art, such as the related structure in the patent document with the publication number of CN214160088U, which will not be elaborated here.

[0033] Preferably, as Figure 1As shown in the figure, the cleaning unit 200 includes a back scrubbing unit 220, which is located at the position of the chair back 510. Specifically, the area of the chair back 510 corresponding to the back scrubbing unit 220 is hollowed out to facilitate the installation of the back scrubbing unit 220. The hollowed-out area can be covered with a towel, and the towel is fixed at the boundary of the hollowed-out area by a clamp. The angle of the back scrubbing unit 220 with respect to the vertical direction of the ground can be freely adjusted along with the angle of the chair back 510 to ensure the comfort of the user during bathing. In addition, during back scrubbing, since the center of gravity of the upper body of the human body moves backward, the back is closely attached to the chair back 510, and the design of using a towel instead of part of the chair back 510 can greatly improve the comfort of the chair back 510 and increase the friction and comfort during back scrubbing.

[0034] Preferably, as Figure 1 , Figure 4 shown, the back scrubbing unit 220 includes a first lead screw slide table kit 221, a main housing 222, and a sub-housing 223. Among them, the main housing 222 and the sub-housing 223 are movably connected by an optical axis so that the distance between the two can be adjusted; the first lead screw slide table kit 221 is connected to the main housing 222 to control the movement of the main housing 222 (or the sub-housing 223) in different directions. The main housing 222 is configured with two stepper motors for generating driving force, and the first lead screw slide table kit 221 is configured with mechanical transmission elements (such as lead screw slide tables, flange plates, optical axes, bearings, etc.) for conducting and converting the driving force. At least two sponge strips 224 are detachably arranged on the side of the sub-housing 223 away from the main housing 222, which are used to perform the function of automatic back scrubbing.

[0035] Preferably, as Figure 1 , Figure 3 , Figure 4 shown, the sponge strips 224 can move in three degrees of freedom of the X, Y, and Z axes under the transmission and support of the first lead screw slide table kit 221. Exemplarily, in the front-back direction (X-axis), the stepper motor installed in the main housing 222 is connected to a spur gear and respectively cooperates with two racks perpendicular to the chair back 510 to realize the function of the sponge strips 224 on the sub-housing 223 moving back and forth. In the horizontal direction (Y-axis), guide rails with parallel ends are installed on the rear side of the chair back 510 and connected to the main housing 222 to control the movement of the sub-housing 223 in the horizontal direction. In the vertical direction (Z-axis), the movement of the sub-housing 223 is controlled by a lead screw, and two optical rods are installed on both sides to fix the sub-housing 223 to the rear side of the chair back 510.

[0036] Preferably, when the back scrubbing unit 220 is operating, the screw slide drives the main housing 222 to move along a predetermined path to the highest point of the back cleaning area. After the sponge strip 224 reaches the target position and stops moving, the relevant structures for telescoping in the first screw slide kit 221 are activated to drive the secondary housing 223 to move to the farthest position in a direction perpendicular to the backrest 510. During this process, the sponge strip 224 on the secondary housing 223 pushes the towel into close contact with the user's back and provides a pressure perpendicular to the human back direction to increase the friction force, thereby achieving more efficient scrubbing. After that, the screw slide drives the sponge strip 224 to move up and down within a certain range to complete the back scrubbing work for this part. After the scrubbing is completed, the secondary housing 223 moves backward under the drive of the telescoping structure and moves downward under the drive of the screw slide to the next scrubbing area, repeating the above process. When the scrubbing of the entire back scrubbing area is completed, the back scrubbing unit 220 stops operating and returns to its original position.

[0037] Preferably, as Figure 1 , Figure 2 shown, the cleaning section 200 includes a hip rinsing unit 230 located behind the bottom of the bathing chair 500, which includes a rinsing nozzle 231. The spraying direction of the rinsing nozzle 231 is from bottom to top and points to the seat surface 520 of the bathing chair 500. To achieve the function of cleaning the user's hips, the middle part of the seat surface 520 is hollowed out and is equipped with a rotating cover plate (not shown in the figure). When the user is not taking a bath, the rotating cover plate is closed to block the hollow; while when the user is taking a bath, the rotating cover plate rotates to expose the hollow. The rinsing nozzle 231 can spray water directly at the hollow part of the seat surface 520 to achieve the cleaning work of the user's hips.

[0038] Preferably, as Figure 1 , Figure 2 shown, the cleaning section 200 includes a leg cleaning unit 240 located at the bottom of the bathing chair 500, which is used to solve the problem that it is difficult for the user to clean the legs and feet in a sitting position due to the decline of physical strength and joint flexibility. Specifically, the leg cleaning unit 240 includes a rotating shaft 242 and a folding platform 241 located at the bottom of the seat surface 520. When in use, the folding platform 241 can rotate around the rotating shaft 242 and move out from the bottom of the seat surface 520 of the bathing chair 500, and can be rotated to be basically level with the height of the seat surface 520, facilitating the user to easily lift the legs in a state of relaxed waist, thereby facilitating the leg cleaning operation. The rotatable design enables the folding platform 241 to be stored under the seat surface 520, which not only significantly reduces the occupied space but also improves the overall portability and practicality of the device.

[0039] Preferably, as Figure 1 , Figure 3As shown in the figure, the auxiliary part 300 includes a second lead screw slider kit 301, an axilla support 302, a sliding connecting piece 303, and an armrest 304. The axilla support 302 is installed on the sliding connecting piece 303 through a fixing device, and the sliding connecting piece 303 is arranged along the optical axis above the armrest 304, allowing the axilla support 302 to linearly slide on the optical axis along with the sliding connecting piece 303. The optical axis, as a guiding element, defines the sliding trajectory of the axilla support 302, enabling it to move in a direction away from or closer to the chair back 510. The top of the axilla support 302 is designed ergonomically to adapt to the axilla shape, ensuring that the user can effectively distribute their body weight on the axilla support 302 while avoiding excessive pressure on the axilla. The armrest 304 is designed in a U-shaped structure to facilitate the user's grasping when standing up or sitting down, so as to prevent the risk of falling. The second lead screw slider kit 301 includes a stepper motor, which provides power and realizes the transmission and conversion of power through a series of mechanical transmission components (such as lead screw sliders, flanges, optical axes, bearings, etc.). The second lead screw slider kit 301 is used to control the vertical movement of the optical axis, and thus adjust the heights of the U-shaped armrest 304 and the axilla support 302 connected to the optical axis to assist the user in completing the sitting and standing actions. Specifically, the armrest 304 is equipped with an up switch and a down switch electrically connected to the stepper motor. When the user is about to sit down, place the axilla support 302 under the axilla and long-press the down switch. The auxiliary part 300 will smoothly lower. At the same time, with the user's sitting-down movement, the axilla support 302 moves towards the chair back 510, guiding the user to the sitting position. After releasing the switch, the auxiliary part 300 stops operating. On the contrary, when the user needs to stand up, place the axilla under the axilla support 302 again and long-press the up switch. The auxiliary part 300 performs the reverse action until assisting the user to reach the standing posture. Release the switch, and the auxiliary part 300 stops operating, completing the auxiliary standing function.

The other two interfaces of the four-valve five-way joint 402 are respectively connected to the valve of the multifunctional shower head 210 through the shower head hose in a threaded connection manner and are connected to the flushing nozzle 231 of the hip flushing unit 230 through the flushing hose.

[0041] Preferably, the functions of the omnidirectional shower arm 110, hip washing unit 230, and back scrubbing unit 220 covered by the present utility model, including rotation, start / stop, and position adjustment, can all be operated through a remote control. These operations involve the angular position control of the servo 114, valve switch control, and linear motion control of the lead screw slide table, and complex control logics can all be achieved through a programmable logic controller (PLC) or other types of controllers widely cited in the prior art. The present utility model does not innovate in the control method but follows the provisions of the Patent Law regarding the protection object of the utility model. The control signal generally adopts wireless transmission technologies such as infrared, Wi-Fi, or Bluetooth to enable the user to remotely control the device. For the convenience of users with declining eyesight, the buttons on the operation panel of the remote control are distinguished by different colors and are printed with relatively large characters, which conforms to the design concept of products for the elderly.

[0042] Preferably, as Figure 4 shown, the present utility model is also equipped with an emergency call device. This device is located on the left side of the bathing chair 500 and includes an emergency alarm button and a waterproof housing, both of which are firmly installed on the structural frame of the bathing chair 500. Given the high privacy and frequency of bathing activities, the risk of encountering an emergency during this process is relatively high. Due to the enclosed nature of the bathing environment, it may be difficult for the user to quickly obtain assistance, and it is also not easy for family members to notice the emergency situation. The user can trigger the emergency alarm button to activate the call-for-help mechanism. Once the button is pressed, a high-volume buzzer built into the product will immediately emit an alarm sound to ensure that family members living with the user can quickly notice and respond to the emergency situation, thereby providing assistance in a timely manner.
