The sheet 22 is positioned outside the exit aperture 14, with the exit aperture 14 opposite the sheet 22.
The specific implementation process is as follows: when the bed sheet 22 is laid on the bed body 8, the motor 4 is started when the part of the bed sheet 22 laid on the top of the bed body 8 needs to be replaced, the motor 4 drives the winding roller 7 and the release roller 6 to rotate anticlockwise through the two belts 5, the release roller 6 releases the clean part of the bed sheet 22, the winding roller 7 winds the used part of the bed sheet 22, and therefore the bed sheet 22 moves from the release roller 6 to the winding roller 7, the bed sheet 22 on the top of the bed body 8 moves rightwards, the clean part of the bed sheet 22 is laid on the bed body 8, and the used part of the bed sheet 22 which is dirty is wound by the winding roller 7.
Meanwhile, the motor 4 drives the cam 3 to rotate, and in the rotating process of the cam 3, the cam 3 intermittently abuts against the bottom end of the piston rod. When the cam 3 abuts against the bottom end of the piston rod, the piston rod drives the piston 25 to move upwards, the piston 25 extrudes the pressure spring 24, the piston 25 compresses gas in the piston cylinder 23, and the gas in the piston cylinder 23 enters the second sliding groove and the first sliding groove through the first gas outlet pipe 9 and the second gas outlet pipe 15 respectively. Gas enters the first sliding groove, air pressure in the first sliding groove is increased, the first sliding rod 19 slides upwards in the first sliding groove under the action of the air pressure, the first tension spring 21 is pulled by the first sliding rod 19, the first sliding rod 19 drives the first rotating roller 20 to move out of the roller groove, the bed sheet 22 on the top of the bed body 8 is upwards pushed up by the first rotating roller 20, and therefore a gap is formed between the bed sheet 22 and the top of the bed body 8, when the bed sheet 22 moves on the bed body 8, friction between the bed sheet 22 and the top of the bed body 8 can be reduced or avoided, and the bed sheet 22 can move on the bed body 8 conveniently. Similarly, get into gas in the second sliding tray, atmospheric pressure grow in the second sliding tray, second slide bar 16 transversely slides in the second sliding tray under the effect of atmospheric pressure, second slide bar 16 stimulates second extension spring 17, second slide bar 16 drives second live-rollers 18 and protrudes from the 8 tip of the bed body, second live-rollers 18 is with the outside jack-up of the 22 of the 8 tip of the bed body, thereby make and have the clearance between the tip of bed sheet 22 and the bed body 8, bed sheet 22 when removing like this, can reduce or avoid the friction between the tip of bed sheet 22 and bed body 8, be favorable to the smooth removal of bed sheet 22. Meanwhile, the air in the piston cylinder 23 also enters the third air outlet pipe 13 and is blown out from the air outlet hole 14, and the blown air blows the bed sheet 22 to shake, so that dirt such as dust adhered to the bed sheet 22 can be shaken off to the ground, the dirt such as dust cannot be adhered to the bed sheet 22 rolled by the rolling roller 7, and the subsequent cleaning work of the bed sheet 22 is facilitated.

Thereby, the gas is supplied to the first sliding groove, the second sliding groove, and the gas outlet hole 14 by the reciprocating movement of the piston 25. In the process of inputting gas, because the first sliding groove and the second sliding groove are both provided with gas leakage holes, the gas in the first sliding groove and the second sliding groove can correspondingly leak, but because the inflation speeds of the first sliding groove and the second sliding groove are both greater than the gas leakage speed, the gas in the first sliding groove and the second sliding groove is continuously increased, so that the gas pressure in the first sliding groove and the second sliding groove is increased, and the first sliding rod 19 and the second sliding rod 16 can be ejected out of the corresponding first sliding groove and the second sliding groove.
After the bed sheet 22 on the top of the bed body 8 is replaced, the motor 4 is turned off, the motor 4 stops rotating, the cam 3 does not intermittently abut against the piston rod any more, the piston cylinder 23 stops filling air into the first sliding groove and the second sliding groove, the air in the first sliding groove and the second sliding groove gradually leaks, the air pressure in the first sliding groove and the second sliding groove is reduced, and the first sliding rod 19 and the second sliding rod 16 reversely move under the action of the first tension spring 21 and the second tension spring 17 respectively to reset. Thus, the first sliding rod 19 drives the first rotating roller 20 into the roller groove, and the second sliding rod 16 drives the second rotating roller 18 to move below the end of the bed body 8.
Example 2
