The other ends of the first air guide pipe 56 and the second air guide pipe 59 are respectively connected to the left and right ends of the second sealed straight pipe 41. The other ends of the exhaust pipe 57 and the air inlet pipe 510 are respectively connected to the left and right ends of the first sealed straight pipe 31. The protective shell 51 is fixed to the support frame 6, and the support frame 6 is used to support the bed plate 1;

[0043] Air filters are installed at the outer ends of the first external connecting pipe 55 and the second external connecting pipe 58. When extracting external air, it is filtered through the air filters;

[0044] Both the first reversing valve 53 and the second reversing valve 54 adopt three-position three-way electromagnetic reversing valves. The first reversing valve 53 is used to switch the connection between the left port of the air pump 52 and the first external connecting pipe 55, the first air guide pipe 56 or the exhaust pipe 57. The second reversing valve 54 is used to switch the connection between the right port of the air pump 52 and the second external connecting pipe 58, the second air guide pipe 59 or the air inlet pipe 510, so as to control the movement of the active block 42 and the intake and exhaust of the air chamber 22 through the air pump 52;

[0045] Please refer to Figure 9, the bottom of the vertical pipe 23 of the air cushion assembly 2 is connected to a magnetic one-way valve 24, which includes a valve body 241, a valve block 242, a limiting rod 243, a support seat 244, a spring 245, a cavity 246, a magnetic block 247, a straight rod 248 and a connecting rod 249. A valve block 242 is provided at the bottom inner side of the valve body 241. The valve block 242 is used to seal the valve port at the bottom end of the valve body 241. The limiting rod 243 is vertically fixed to the top of the valve block 242. The limiting rod 243 vertically penetrates the support seat 244, and the support seat 244 is fixed to the inner top of the valve body 241. The top of the valve block 242 is connected to the inner top of the valve body 241 by a spring 245. It is elastically connected to the support seat 244, and the spring 245 is sleeved on the outside of the limiting rod 243. The valve body 241 is provided with cavities 246 on both the front and rear sides, and a fifth magnet 247 is provided in each of the two cavities 246. A straight rod 248 is fixed to the inner end of the fifth magnet 247. The other end of the straight rod 248 passes through the inner wall of the cavity 246 and is rotatably connected to the top of the connecting rod 249 via a rotating shaft. The bottom end of the connecting rod 249 is rotatably connected to the limiting rod 243 via a rotating shaft. The fifth magnet 247 and the fourth magnet 247 are attracted to each other. The top of the valve body 241 is connected to the vertical pipe 23, and the bottom end of the valve body 241 is connected to the connecting pipe 37.

[0046] The connecting rod 249 is arranged at an angle, and the distance between the two connecting rods 249 gradually decreases from top to bottom. When the fourth magnet 47 moves to align with the fifth magnet 247, the fourth magnet 47 attracts the fifth magnet 247, causing the fifth magnet 247 to move outward. The fifth magnet 247 drives the top of the connecting rod 249 to move outward through the straight rod 248, causing the connecting rod 249 to drive the limit rod 243 and the valve block 242 to move upward, thereby disconnecting the valve block 242 from blocking the valve port at the bottom of the valve body 241.

[0047] The outer diameter of the valve block 242 gradually decreases from top to bottom. The spring 245 presses against the top of the valve block 242 so that the valve block 242 can unidirectionally block the valve port at the bottom of the valve body 241 .

[0048] Magnetic block one 33, magnetic block two 43, magnetic block three 45, magnetic block four 47 and magnetic block five 247 are all made of neodymium iron boron, which has high magnetic energy storage and ensures the adsorption force in the air.

[0049] The present invention provides an improved cleaning nursing bed for patients, and its working principle is as follows:

[0050] First, inflate the air cushion assembly 2. Control the first reversing valve 53 and the second reversing valve 54 to connect the two ports of the air pump 52 to the first air duct 56 and the second air duct 59 respectively. Control the air pump 51 to work. Extract the air from the left side inside the second sealed straight pipe 41 through the first air duct 56, and inject the extracted air into the right side inside the second sealed straight pipe 41 through the second air duct 59, so that the active block 42 inside the second sealed straight pipe 41 moves to the leftmost end. The second magnet 43 inside the active block 42 adsorbs with the third magnet 45 inside the driven block 44, so that the active block 42 drives the driven block 44 to move synchronously to the left, and the third magnet 45 inside the driven block 44 adsorbs with the first magnet 33 at the bottom of the movable pipe 32, so that the movable pipe 32 moves synchronously to the left to the first sealed straight pipe 31. Then control the first reversing valve 53 and the second reversing valve 54 to connect the two ports of the air pump 52 to the first external connection pipe 55 and the air inlet pipe 510 respectively. Control the air pump 51 to work. Extract the external air through the first external connection pipe 55, and inflate the right side inside the first sealed straight pipe 31 through the air inlet pipe 510. When inflating, the air inside the first sealed straight pipe 31 pushes the valve block 242 upward, so that the air passes through the magnetic adsorption one-way valve 24 and the vertical pipe 23 and enters the air chamber 22 of the air cushion main body 21, and inflates each air chamber 22 at the same time, and ensures that the air pressure of each air chamber 22 is constant;

[0051] Second, after the air cushion assembly 2 is inflated, control the movable pipe 32 to move to the right end, so that the exhaust chamber 34 of the movable pipe 32 is connected to the air chamber 22 on the rightmost side of the air cushion main body 21. At this time, the fourth magnet 47 is aligned with the position of the magnetic adsorption one-way valve 24 at the bottom of the rightmost air chamber 22. Adsorb the fifth magnet 247 through the fourth magnet 47, so that the fifth magnet 247 moves outward. The fifth magnet 247 drives the top of the connecting rod 249 to move outward through the straight rod 248, so that the connecting rod 249 drives the limiting rod 243 and the valve block 242 to move upward, disconnecting the blockage of the valve block 242 to the valve orifice at the bottom of the valve body 241. Then control the air pump 51 to extract the air from the rightmost air chamber 22, so that a depression is formed in the air chamber 22. The depressed air chamber forms a cleaning operation space, and the skin at the bottom of the patient is cleaned through the depressed area;

[0052] Perform the exhaust operation on the air chambers 22 in sequence from right to left, and the air discharged from the air chambers 22 is transported to the right side of the first sealed straight pipe 31 to inflate the air chamber 22 on the right side of the depressed air chamber 22, ensuring that the air volume of the air chambers 22 except the depressed air chamber 22 is sufficient, and further ensuring the support effect on the patient. By sequentially depressing the air chambers 22 from right to left, the skin at the bottom of the patient is sequentially cleaned;

[0053] Moreover, a single air chamber 22 can be depressed, and the air chamber 22 corresponding to the skin to be cleaned at the bottom of the patient is separately exhausted, and the discharged air is discharged through the second external connection pipe 58, so that the skin to be cleaned at the bottom of the patient can be cleaned;

[0054] It ensures the effective dispersion of pressure on the weight-bearing parts of the patient's body, enables the cleaning tool to come into more sufficient contact with skin folds and hidden areas, improves the cleaning effect, and automatically restores comfortable support after cleaning is completed.
