Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Fig. 1, the present invention provides a portable nursing device, including a lifting frame 100, a cleaning control mechanism 200 and a pin mechanism 300. The lifting frame 100 includes a movable base 110, a foldable column 120 and a pulley mechanism 130, wherein the movable base 110 and the foldable column 120 are rotatably connected, so that the movable base 110 and the foldable column 120 can be switched between a state parallel to each other or a state perpendicular to each other, and furthermore, the pulley mechanism 130 is connected to the foldable column 120, and when the foldable column 120 is in an open state, the disabled person can be displaced by the pulley mechanism 130, for example, he can be moved away from the bed to facilitate cleaning.

The cleaning control mechanism 200 includes a control box 21 that cooperates with the lifting frame 100 and a cleaning unit 22 that can be received in the control box 21 .

For the purpose of convenient carrying, the foldable column 120 is folded when not in use to reduce its volume. Specifically, the foldable column 120 includes a first column 121, a second column 122, and a connecting column 123 disposed between the first column 121 and the second column 122, and the number of the connecting column 123 is at least one.

This article takes the number of the connecting column 123 as one for illustration. The base 110, the first column 121, the connecting column 123 and the second column 122 can be switched between a rotatable state and a fixed state through the pin mechanism 300. The pin mechanism 300 may include the first pin 310, the second pin 320, the third pin 330, the fourth pin 340, the fifth pin 350 and the sixth pin 360 described below, or other pins for realizing rotation.

The first end of the first column 121 (e.g., the lower end shown in FIG. 1 ) is rotatably connected to the base 110. Specifically, the first end of the first column 121 is connected to the base 110 through the first pin 310 and the second pin 320. The first column 121 is configured such that when the second pin 320 is connected to the first end of the first column 121 and the base 110, respectively, the first end of the first column 121 and the base 110 cannot rotate. As shown in FIG. 2 , the first column 121 and the base 110 are perpendicular to each other, and two first ears 1211 are respectively provided at both sides of the lower end of the first column 121. The base 110 is configured as an L-shaped component. The two first ears 1211 of the first column 121 are rotatably connected to the horizontally extending surface and the vertically extending surface of the base 110 through the first pin 310 and the second pin 320, respectively.

When the first pin 310 and the second pin 320 respectively penetrate the two first ears 1211 at both sides of the lower end of the first column 121, the first column 121 can be fixed to the base 110 in a manner perpendicular to the base 110. When the second pin 320 is separated from the first end of the first column 121 and the base 110, the first column 121 can rotate with the first pin 310 as the rotation axis. As shown in FIG. 4, the second pin 320 is 320 is removed from the first ear 1211 of the first column 121, the first column 121 can be rotated counterclockwise with the first pin 310 as the rotation axis to be parallel to the base 110, so that the first column 121 and the base 110 are folded. In addition, due to the blocking effect of the vertically extending surface of the base 110, when the first column 121 is rotated clockwise with the first pin 310 as the rotation axis to be unfolded, the first column 121 can be rotated to be perpendicular to the base 110 at most.

The second end of the first column 121 (for example, the upper end shown in Figure 1) is rotatably connected to the connecting column 123, and the second end of the first column 121 is connected to the connecting column 123 through the third pin shaft 330 and the fourth pin shaft 340, and the connecting column 123 is connected to the second column 122 through the fifth pin shaft 350 and the sixth pin shaft 360.

Among them, the connecting column 123 is constructed so that when the fourth pin shaft 340 is respectively connected to the second end of the connecting column 123 and the first column 121, the second end of the connecting column 123 and the first column 121 cannot rotate; when the fourth pin shaft 340 is detached from the second end of the connecting column 123 and the first column 121, the connecting column 123 can rotate with the third pin shaft 330 as the rotation axis.

As shown in Fig. 1, Fig. 2 and Fig. 3, Fig. 1 shows the unfolded state in which the connecting column 123 and the first column 121 are in the same line, and Fig. 3 shows the state in which the connecting column 123 is rotated to be parallel to the first column 121. As shown in Fig. 1 and Fig. 3, a limit block 1212 is provided at the second end of the first column 121, and a stop block 1231 and a third ear portion 1232 are provided at both sides of the connecting column 123. The third ear portion 1232 is rotatably connected to the first column 121 through the third pin shaft 330, so when the connecting column 123 rotates counterclockwise with the third pin shaft 330 as the rotation axis to be in the same line with the first column 121, the stop block 1231 cooperates with the limit block 1212, and the fourth pin shaft 340 penetrates the stop block 1231 and the limit block 1212, so that the connecting column 123 and the first column 121 can be fixed, that is, the connecting column 123 and the first column 121 are in the open state shown in Fig. 1.

When the fourth pin 340 is removed, there is no constraint between the stopper 1231 and the limit block 1212, so the connecting column 123 can rotate clockwise with the third pin 330 as the rotation axis to a folded state parallel to the first column 121, as shown in FIGS. 2 and 3.

The above description only illustrates an embodiment in which there is one connecting column 123, but it can be understood that there can be multiple connecting columns 123, and multiple connecting columns 123 are connected end to end in sequence. Through the connecting action of the pin mechanism 300, each connecting column 123 can be unfolded or folded.

The connecting column 123 is also rotatably connected to the second column 122 (when there are multiple connecting columns 123, the connecting column 123 located on the outermost side after folding is rotatably connected to the second column 122), so that the first column 121, the connecting column 123 and the second column 122 are all rotated to a folded state parallel to the base 110 (as shown in FIG. 4), or the first column 121 and the connecting column 123 are all rotated to an open state perpendicular to the base 110 and the second column 122 is parallel to the base 110 (as shown in FIG. 1).

Among them, the second column 122 is constructed so that when the sixth pin shaft 360 is respectively connected to the second column 122 and the connecting column 123, the second column 122 and the connecting column 123 cannot rotate; when the sixth pin shaft 360 is detached from the second column 122 and the connecting column 123, the second column 122 can rotate with the fifth pin shaft 350 as the rotation axis.

As shown in FIG3 , a trapezoidal stopper 1233 is provided at the end of the connecting column 123, and the second ear 1221 of the second column 122 is connected to the trapezoidal stopper 1233 via the fifth pin 350. The sixth pin 360 penetrates the end of the second column 122 and the trapezoidal stopper 1233, so that the second column 122 and the connecting column 123 are in an open state perpendicular to each other (at this time, the second column 122 is parallel to the base 110). When the sixth pin 360 is removed, the second column 122 rotates counterclockwise with the fifth pin 350 as the rotation axis until the connecting columns 123 are in a folded state parallel to each other.

As shown in FIG1 , when the foldable column 120 is fully opened, the first column 121 is perpendicular to the base 110, the connecting column 123 is colinear with the first column 121, and the second column 122 is perpendicular to the connecting column 123. As shown in FIG4 , when the foldable column 120 is fully folded, the first column 121, the connecting column 123, and the second column 122 are sequentially stacked in parallel on the base 110. In addition, when the foldable column 120 is folded, the first column 121 and the connecting column 123 can be folded first, that is, folded from the fully opened state shown in FIG1 to the partially folded state shown in FIG3; then the second column 122 and the connecting column 123 are folded, and finally the first column 121 and the base 110 are folded. It can be understood that the above folding order is not necessary, and the second column 122 and the connecting column 123 can be folded first, or the first column 121 and the base 110 can be folded first, etc.

Therefore, when the foldable column 120 is not in use, it can be completely folded, thereby reducing its occupied space and facilitating transportation and carrying.

The number of the foldable columns 120 is at least two. Optionally, the number of the bases 110 corresponds to the number of the foldable columns 120 one by one. As shown in FIG8 , the two foldable columns 120 are respectively arranged on the corresponding sides of the two bases 110. In order to improve the support strength of the lifting frame 100, a plurality of detachable third columns 140 are also arranged between the two foldable columns 120. The plurality of third columns 140 are arranged at intervals along the Z-axis direction shown in FIG8 , so that the third column 140 is detachably connected to the first column 121, the second column 122 and the connecting column 123, respectively. In addition, a detachable third column 140 may also be arranged between the two bases 110 to enhance strength (as shown in FIG8 and FIG9 ). The appropriate position and number of the third column 140 may be selected according to actual needs.

As shown in FIG8 , the two first columns 121, the two second columns 122, and the two connecting columns 123 are all connected via a third column 140, so that the two foldable columns 120 can be connected into a whole to improve their bearing capacity. The column 140 extends in the longitudinal direction (the Y-axis direction shown in FIG. 8 ) of the lifting frame 100. The base 110 extends in the horizontal direction (the X-axis direction shown in FIG. 1 ) of the lifting frame 100.

Optionally, the base 110 may also be provided as an integral structure, so that two foldable columns 120 may be provided on both sides thereof respectively.

The lifting frame 100 supports a pulley mechanism 130 , which is used to transfer the disabled person 400 , for example, to transfer the disabled person 400 from the bed to a location convenient for cleaning, or to transfer the disabled person to another supporting device.

As shown in Figures 5 to 8, the pulley mechanism 130 includes a first fixed pulley 131, a second fixed pulley 132, a movable pulley 134 and a rope tightener 135. In order to better explain the pulley mechanism 130, please refer to Figure 1 and illustrate the state in which the foldable column 120 is fully opened.

The first fixed pulley 131 and the second fixed pulley 132 are both arranged on the second column 122. As shown in Fig. 1, when the foldable column 120 is unfolded, the second fixed pulley 132 and the first fixed pulley 131 are staggered with each other in the extension direction of the second column 122 (i.e., the X-axis direction shown in Fig. 1), and the first traction rope 136 and the second traction rope 137 passing through the first fixed pulley 131 and the second fixed pulley 132 are staggered with each other in the X-axis direction shown in Fig. 1, so that when the disabled person 400 is transferred, the first traction rope 136 and the second traction rope 137 can respectively apply force from both sides of the disabled person 400.

As shown in Fig. 7, two pulley mechanisms 130 are shown, and the two pulley mechanisms 130 correspond to the two foldable columns 120 on the left and right sides shown in Fig. 8, so the two pulley mechanisms 130 can also be arranged to be symmetrical to each other. The following description takes the pulley mechanism 130 located at the bottom as an example.

As shown in FIG7 , the number of the first fixed pulley 131 is one, the number of the second fixed pulley 132 is two, and the two second fixed pulleys 132 are arranged at intervals along the X-axis. As shown in FIG7 , one of the second fixed pulleys 132 is staggered with the first fixed pulley 131 in the X-axis direction, and the other second fixed pulley 132 is arranged side by side with the first fixed pulley 131. Such an arrangement allows the first traction rope 136 to pass through the first fixed pulley 131, and the second traction rope 137 to pass through the two second fixed pulleys 132 in sequence, so that the first traction rope 136 and the second traction rope 137 can be staggered in the X-axis direction, thereby the first traction rope 136 and the second traction rope 137 can respectively carry the weight of both sides of the body of the disabled person 400.

Furthermore, in order to simultaneously drive the first traction rope 136 and the second traction rope 137, the pulley mechanism 130 further includes a guide wheel 133, and the guide wheel 133 is connected to one end of the connecting column 123 close to the second column 122. As shown in FIG1 , the guide wheel 133 is located at the transition between the connecting column 123 and the second column 122. Therefore, when the foldable column 120 is unfolded, the guide wheel 133 is located at the same height as the first fixed pulley 131 and the second fixed pulley 132.

8 , the guide wheel 133 includes two side-by-side wheels, which correspond to the first fixed pulley 131 and one of the second fixed pulleys 132 , respectively, so that the guide wheel 133 can receive the first traction rope 136 and the second traction rope 137 , respectively.

As shown in FIG1 , the movable pulley 134 is disposed on the first column 121, and the movable pulley 134 is connected to the first fixed pulley 131 through the first traction rope 136, and the movable pulley 134 is connected to the second fixed pulley 132 through the second traction rope 137. Specifically, the first traction rope 136 and the second traction rope 137 respectively pass through the first fixed pulley 131 and the second fixed pulley 132, and then pass through the guide wheel 133 and the movable pulley 134 in sequence, and are fixed to the fixing portion 138 on the connecting column 123. That is, one end of the first traction rope 136 is used to be fixed to the sling 410 carrying the disabled person 400, and the other end passes through the first fixed pulley 131 located at the top of FIG7 in sequence, and then passes through a wheel in the guide wheel 133 and a wheel of the movable pulley 134, and the direction is changed after passing through the movable pulley 134, and then fixed to the fixing portion 138 on the connecting column 123. One end of the second traction rope 137 is used to be fixed to the sling 410 carrying the disabled person 400, and the other end passes through the two second fixed pulleys 132 in sequence, and then passes through the other wheel of the guide wheel 133 and the other wheel of the movable pulley 134. After passing through the movable pulley 134, the direction is changed and then fixed to the fixing part 138 on the connecting column 123.

The rope tightener 135 is disposed in the first column 121 and connected to the movable pulley 134. When the rope tightener 135 is in operation, it pushes the movable pulley 134 to move along the extension direction of the first column 121, thereby changing the height of the hanging end (i.e., the end connected to the sling 410) of the first traction rope 136 and/or the second traction rope 137, thereby changing the position of the sling 410, so that the disabled person 400 can be lifted.

In the illustrated embodiment, the number of pulley mechanisms 130 corresponds to the number of foldable columns 120 , that is, each foldable column 120 is provided with a pulley mechanism 130 . Please refer to Figures 1, 5 and 9. The pulley mechanism 130 on one of the foldable columns 120 can be connected to the position on the sling 410 corresponding to the shoulder of the disabled person 400, and the pulley mechanism 130 on the other foldable column 120 can be connected to the position on the sling 410 corresponding to the leg of the disabled person 400, so that when each pulley mechanism 130 is controlled to be lifted and lowered respectively, not only the position of the disabled person 400 but also his posture can be changed; for example, the lifting and lowering of each pulley mechanism 130 is controlled to be roughly synchronous, so that the disabled person 400 is in a lying posture in the sling 410 (the posture of the disabled person 400 as shown in Figure 8), so as to facilitate the transfer of the disabled person 400 to other supporting devices; or one of the pulley mechanisms 130 can be controlled to rise higher, so that the disabled person 400 is in a semi-lying posture (the posture of the disabled person 400 as shown in Figure 9) or a sitting posture (the posture of the disabled person 400 as shown in Figure 10) in the sling 410. The posture of the staff 400) can be used to clean the disabled staff after defecation.

In addition, since the bottom of the base 110 is provided with rollers 111 , when the disabled person 400 is lifted, the lifting frame 100 can be moved by the rollers 111 , so that the disabled person 400 can be transferred to a desired position.

As shown in Figures 8 to 12, the cleaning control mechanism 200 cooperates with the lifting frame 100. Specifically, the control box 21 of the cleaning control mechanism 200 can be arranged between two foldable columns 120, and when the lifting frame 100 moves the disabled person 400 to a suitable position, the cleaning unit 22 on the control box 21 can perform a cleaning operation on the disabled person 400.

Specifically, as shown in Figures 13 to 18, the cleaning unit 22 includes a movable seat 223, a first arm 220, and a second arm 230. As shown in Figures 11 and 15, the movable seat 223 is slidably disposed on the control box 21. As shown in Figure 14, the rear end of the first arm 220 (i.e., the right end in the orientation shown in Figure 14) is rotatably connected to the movable seat 223, and the first arm 220 can rotate with the pivot point H between it and the movable seat 223 as the rotation point. For example, the first arm 220 and the second arm 230 can rotate from the initial state shown in Figure 14 to the intermediate open state shown in Figure 16, and the second arm 230 can further rotate to the fully open state shown in Figure 13.

The rear end of the second arm 230 (i.e. the left end in the orientation shown in FIG. 14 ) is hinged to the first arm 220 , and the front end of the second arm 230 (i.e. the right end in the orientation shown in FIG. 14 ) is provided with a rotatable cleaning head 260 .

As shown in Fig. 14, it is a schematic diagram of the folded state of the cleaning unit 22. The first arm 220 and the second arm 230 are parallel to each other, or it can be considered that the angle between the first arm 220 and the second arm 230 is close to 0° at this time.

Please continue to refer to Figure 14. The moving seat 223 is also provided with a first driving rod 240 and a second driving rod 250, wherein one end of the first driving rod 240 (i.e., the right end in the orientation shown in Figure 14) is rotatably connected to the moving seat 223. As shown in Figure 14, the first driving rod 240 can rotate with the pivot point G between it and the moving seat 223 as the rotation point. For example, the first driving rod 240 can rotate from the initial state shown in Figure 14 to the intermediate open state shown in Figure 16, and can also rotate to the fully open state shown in Figure 13. The other end of the first driving rod 240 (i.e., the left end in the orientation shown in Figure 14) is rotatably connected to the first arm 220.

Among them, in the initial state shown in Figure 14, the second arm 230 is parallel to the first arm 220, and both are parallel to the movable seat 223, so the cleaning unit 22 is in a folded state; in the intermediate open state shown in Figure 16, the first arm 220 is driven by the first driving rod 240 to rotate to a state approximately perpendicular to the movable seat 223, and the second arm 230 is also driven by the first arm 220 to rotate to a state approximately perpendicular to the movable seat 223, at which time the first arm 220 and the second arm 230 are still approximately parallel; in the fully open state shown in Figure 13, the first arm 220 and the first driving rod 240 are still in a state approximately perpendicular to the movable seat 223, and the second arm 230 is driven by the second driving rod 250 to rotate to have an angle with the first arm 220.

The end of the first driving rod 240 is rotatably connected to a transfer rod 241 , and the transfer rod 241 is formed integrally with the first arm 220 . Therefore, the first driving rod 240 and the first arm 220 can rotate around a pivot point A as a rotation point.

Further, one end of the second driving rod 250 (i.e., the left end in the orientation shown in FIG. 14 ) is rotatably connected to the first arm 220 and the second arm 230. Specifically, the front end of the first arm 220 is provided with a first curved rod 221, which is integrally formed with the transfer rod 241, and the two form a roughly V-shaped structure.

A second curved rod 222 is provided at the rear end of the second arm 230, and the first curved rod 221 and the second curved rod 222 are hinged. As shown in FIG. 14 , the first curved rod 221 and the second curved rod 222 are hinged at point C, and the two rotate around the hinge point C as the rotation point.

A Y-shaped connector 251 is provided at one end of the second driving rod 250, and the two ends of the Y-shaped connector 251 are respectively connected to the first arm 220 and the second arm 230 for rotation, so as to adjust the angle between the first arm 220 and the second arm 230. As shown in FIG14, the Y-shaped connector 251 has a main body 2513, a first branch 2511 and a second branch 2512. Among them, the first branch 2511 and the second branch 2512 are both connected to the main body 2513 for rotation, that is, the two can rotate with the pivot point E as the rotation point. The main body 2513 is fixedly connected to the front end of the second driving rod 250 (i.e., the left end in the orientation shown in FIG14), and its fixed point is L. In addition, the end of the first branch 2511 is connected to the first arm 220 for rotation, and the two rotate with the pivot point B as the rotation point; the end of the second branch 2512 is connected to the second arm 230 for rotation (specifically, connected to the second curved rod 222 of the second arm 230 for rotation), and the two rotate with the pivot point D as the rotation point.

The other end of the second driving rod 250 (i.e. the right end in the orientation shown in FIG. 14 ) is rotatably connected to the moving seat 223. As shown in FIG. 14 , the second driving rod 250 can rotate with the pivot point K between the second driving rod 250 and the moving seat 223 as the rotation point.

As shown in Figures 13 and 14, the second driving rod 250 drives the Y-shaped connecting member 251, and its main body 2513 and the first branch 2511 and the second branch 2512 rotate around the pivot point E, changing the angle between the two, thereby pushing the second arm 230 to rotate around the pivot point C, so that the angle between the second arm 230 and the first arm 220 changes, and the second arm 230 opens.

14 and 17, the second arm 230 includes a pivot arm 2301 and a fixed arm 2302. The pivot arm 2301 is connected to the fixed arm 2302. The pivot point F of 2302 is the rotation point for rotation. The pivot arm 2301 is connected to the cleaning head 260 , and a third driving rod 280 is arranged below the pivot arm 2301 .

As shown in FIG. 17 , the front end of the third driving rod 280 is provided with a first connecting rod 281, and the rear end thereof is provided with a second connecting rod 282, wherein the first connecting rod 281 is also connected to the pivot arm 2301, and the second connecting rod 282 is also connected to the fixed arm 2302. Driven by the third driving rod 280, the pivot arm 2301 can rotate with the pivot point F as the rotation point to have an angle with the fixed arm 2302, or be colinear with the fixed arm 2302, so that the second arm 230 can drive the cleaning head 260 thereon to be raised or lowered to change the angle between it and the fixed arm 2302. It can be understood that the first connecting rod 281 and the second connecting rod 282 are both rotatably connected to the third driving rod 280, and when the third driving rod 280 drives the pivot arm 2301 to rotate, the angle between the first connecting rod 281 and the third driving rod 280 and the angle between the second connecting rod 282 and the third driving rod 280 will change accordingly.

As shown in Figures 9, 11 and 12, a slide rail 211 and a first driver 212 are also provided on the control box 21. The slide rail 211 extends along the height direction of the control box 21 (i.e., the Z-axis direction shown in Figure 9); the movable seat 223 is arranged on the slide rail 211, and the first driver 212 is respectively connected to the inner wall of the control box 21 and the movable seat 223 to drive the movable seat 223 to slide on the slide rail 211, thereby changing the height of the cleaning head 260.

For example, the second driver 270 may be a motor, and the first driver 212 , the first driving rod 240 , the second driving rod 250 , and the third driving rod 280 may be electric push rods.

Please refer to Figures 10, 11 and 12, the control box 21 is roughly divided into three layers in its height direction (Z-axis direction), wherein the top layer is arranged with electrical components (not shown), which are electrically connected to the above-mentioned drivers and driving rods, so as to send instructions to the drivers and driving rods to make them move. The slide rail 211 is arranged on the second layer of the control box 21, and the cleaning unit 22 is also accommodated in the second layer of the control box 21, so under the action of the first driver 212, the range of movement of the movable seat 223 on the slide rail 211 is limited to the height range of the second layer of the control box 21. When in use, the cleaning head 260 in the cleaning unit 22 can be extended along the negative direction of the X-axis shown in Figure 10 under the action of each driver and each driving rod, so as to perform a cleaning operation. The bottom layer of the control box 21 is arranged with devices such as the water tank 215 and the water pump 214 described below.

As shown in Fig. 17 and Fig. 18, the cleaning head 260 includes a cleaning brush head 261, a water spray head 262 and a warm air spray head 263 arranged on the second driver 270. Specifically, a connecting shaft 2611 is arranged at the rear end of the cleaning brush head 261, and two bearing seats 264 are arranged on the pivot arm 2301 of the second arm 230. The connecting shaft 2611 passes through the two bearing seats 264 in sequence and is connected to the coupling 265. The pivot arm 2301 is connected to the cleaning brush head 261 through the bearing seat 264.

Furthermore, a driver bracket 266 is also provided on the pivot arm 2301, and the driver bracket 266 is connected to the second driver 270. Therefore, the connecting shaft 2611 is connected to the output shaft of the second driver 270 through the coupling 265, so that the second driver 270 can drive the cleaning brush head 261 to rotate along its axial direction.

The angle of the clean water nozzle 262 is adjustable, and the angle of the warm air nozzle 263 is adjustable.

Optionally, as shown in FIG18 , the clean water nozzle 262 is connected to the water pipe 213 through a first hose 2621, and the warm air nozzle 263 is connected to the air pipe 218 through a second hose 2631. The water pipe 213 and the air pipe 218 can be fixed to the pivot arm 2301, so that the angle and/or posture of the clean water nozzle 262 can be adjusted by the first hose 2621, or the angle or posture of the warm air nozzle 263 can be adjusted by bending the second hose 2631. Therefore, the clean water nozzle 262 and the warm air nozzle 263 can adjust their angles in the up-down direction (Z-axis direction) and the left-right direction (Y-axis direction).

The first hose 2621 and the second hose 2631 may both be metal bellows, which have a certain strength and can support the clean water nozzle 262 and the warm air nozzle 263 .

Optionally, as shown in FIG. 19 , the clean water nozzle 262 is connected to the water pipe 213 via a first universal adapter 2622, and the warm air nozzle 263 is connected to the air pipe 218 via a second universal adapter 2632. The angle and/or posture of the first clean water nozzle 262 can be adjusted by the first universal adapter 2622, and the angle and/or posture of the warm air nozzle 263 can be adjusted by the second universal adapter 2632. By providing the first universal adapter 2622 and the second universal adapter 2632, the clean water nozzle 262 and the warm air nozzle 263 can adjust their angles in all directions.

Further optionally, as shown in FIG. 20 , the clean water nozzle 262 is connected to the water pipe 213 via a first hose 2621, and the warm air nozzle 263 is connected to the air pipe 218 via a second hose 2631. In addition, the clean water nozzle 262 is also connected to the pivot arm 2301 of the second arm 230 via a first universal joint 2622, and the warm air nozzle 263 is also connected to the pivot arm 2301 of the second arm 230 via a second universal joint 2632. Since the first universal joint 2622 and the second universal joint 2632 are respectively connected to the pivot arm 2301 of the second arm 230, The angles and/or postures of the first clean water nozzle 262 and the warm air nozzle 263 can be adjusted in a wider range through the first universal joint 2622 and the second universal joint 2632, and the first hose 2621 and the second hose 2631 can change the bending direction accordingly.

The water pipe 213 is connected to the water tank 215 at the bottom layer of the control box 21, and specifically, it is connected to the water pump 214 in the water tank 215, as shown in FIG9. The clean water in the water tank 215 can be pumped to the clean water nozzle 262 for flushing through the water pump 214. The air duct 218 is connected to the heater 219 at the bottom layer of the control box 21, and the heater 219 blows warm air to the warm air nozzle 263 to dry the washed parts of the disabled person 400 with hot air.

In addition, a water receiving tray 217 can be placed under the cleaning head 260, which is set on the waste water tank 216 and is connected to the waste water tank 216. The flushing water sprayed by the clean water nozzle 262 can be received in the water receiving tray 217 and flow into the waste water tank 216 for collection.
