[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] See also Figure 1 、 Figure 5 、 Figure 6 and Figure 7A cleaning and disinfection device for a bed wheelchair includes a water tank 1, a flushing water pump 3, a limit assembly 4 and a cleaning assembly 7. The outer wall of the water tank 1 is installed with a flushing water pump 3, and the outer walls on both sides of the water tank 1 are installed with limit assemblies 4. The top of the water tank 1 is installed with a cleaning assembly 7, and the cleaning assembly 7 includes a fixed box 70 installed above the outlet of the water tank 1. A plurality of fans 71 are installed on the top of the fixed box 70. The air outlet of the fan 71 is installed with a plurality of jet pipes 72. The inner wall of the fixed box 70 is installed with The first motor 73, the output end of the first motor 73 is installed with a rotating shaft 75, the outer wall of the rotating shaft 75 is installed with a collision rod 74, the bottom wall of the fixed box 70 is penetrated by a lifting rod 8, the top of the lifting rod 8 is installed with a collision plate 81, the bottom of the lifting rod 8 is installed with an electromagnetic heating coil 82, the inner wall of the electromagnetic heating coil 82 is installed with a support rod 83, the outer wall of the lifting rod 8 is installed with an extrusion rod 84, the outer wall of the lifting rod 8 is installed with a limit plate 85, and the bottom of the limit plate 85 is installed with a second spring 86.

[0036] Specifically, when the backrest and armrests of the bed wheelchair are cleaned, the wheels and frame of the bed wheelchair move to the outlet of the water tank 1. At this time, the first motor 73 rotates to drive the rotating shaft 75 to rotate, and the rotation of the rotating shaft 75 drives the impact rod 74 to rotate. The rotation of the impact rod 74 squeezes the impact plate 81. The impact plate 81 drops after being squeezed, and the lifting rod 8 drops accordingly. The lifting rod 8 drops and drives the electromagnetic heating coil 82 to drop. At this time, the electromagnetic heating coil 82 drops. At this time, the electromagnetic heating coil 82 covers the wheel axle part. The electromagnetic heating coil 82 is energized to dissipate heat, which quickly increases the temperature of the wheel axle part, so that the temperature of the wheel axle part quickly reaches hundreds of degrees Celsius, thereby heating the hair wrapped around the wheel axle, so that the hair can be ignited, thereby achieving the hair cleaning function;

[0037] It should be noted that when the lifting rod 8 descends, the limit plate 85 is driven to descend, and the descent of the limit plate 85 drives the second spring 86 to contract. When the impact rod 74 no longer presses the impact plate 81, the second spring 86 can drive the lifting rod 8 back to its original position.

[0038] It should be noted that the temperature of the electromagnetic heating coil 82 can be raised to thousands of degrees. In this device, it is only necessary to raise the temperature to between 300-400 degrees. The metal used in the frame of the bed wheelchair is mostly aluminum alloy or steel. The melting point of aluminum alloy is between 482-660°C, and the melting point of steel is 1515°C. The ignition point of hair is 70-90°C, and the ignition point of fabric is mostly below 200°C. Therefore, when the electromagnetic heating coil 82 heats the wheel axle part, hair and fabric threads can be ignited by the high temperature, thereby cleaning the wheel axle. The above heating method will not damage the support frame of the bed wheelchair, and it is more convenient to clean than traditional handheld knives. Traditional cleaning of hair entanglement also requires the use of tape, which sticks to the hair and removes the hair. However, the tape removal method may cause tangled hair to be unable to be stuck off, making cleaning complicated. This device cleans by burning the hair and fabric threads, which can speed up the cleaning speed.

The inner wall of the water tank 1 is equipped with multiple transmission shafts 21, the outer wall of the transmission shaft 21 is equipped with a chain 22, the outer wall of the chain 22 is equipped with multiple load-bearing plates 23, and the top of the load-bearing plate 23 is equipped with multiple cleaning brushes 24. The outer wall of the support frame 11 is equipped with a second water pump 31, and the outer wall of the water tank 1 is equipped with a storage box 32. The input ends of the flushing water pump 3 and the second water pump 31 are both equipped with water inlet pipes, and one end of the water inlet pipes extends into the interior of the storage box 32. Multiple connecting pipes 33 are installed on the top of the water tank 1, and the connecting pipes 33 are connected to the output ends of the flushing water pump 3 and the second water pump 31, and the outer wall of the connecting pipe 33 is equipped with multiple flushing nozzles 34.

[0040] Specifically, first adjust the bed wheelchair to the bed posture so that the backrest and seat cushion are in the same plane, then place one side of the backrest and seat cushion on the load-bearing plate 23, then start the drive motor 2, the drive motor 2 rotates to drive the transmission shaft 21 to rotate, the transmission shaft 21 drives the chain 22 and multiple load-bearing plates 23 to rotate, thereby driving the bed wheelchair to move toward the inside of the water tank 1, and at the same time the flushing water pump 3 and the second water pump 31 work to draw out the disinfectant in the storage tank 32, and flush it downward through the flushing nozzle 34 to clean and disinfect the back of the bed wheelchair and the axle frame.

[0041] See also Figure 2 、 Figure 3 and Figure 4The limit assembly 4 includes an adjustment box 40 installed on the outer walls of both sides of the water tank 1. A fixed shaft 41 is installed on the inner wall of the adjustment box 40. A lever 42 is installed on the outer wall of the fixed shaft 41. A movable shaft 43 is installed at both ends of the lever 42. A pad 44 is installed at one end of the movable shaft 43 at the upper end of the lever 42. A fixing hole 45 is opened on the inner wall of the water tank 1, and the pad 44 is located inside the fixing hole 45. The cross-section of the pad 44 is triangular. An electric telescopic rod 5 is installed on the inner wall of the adjustment box 40, and one end of the electric telescopic rod 5 is fixedly connected to the outer wall of the lever 42. A return spring 5 is installed on the inner wall of the adjustment box 40. 1, and one end of the return spring 51 is fixedly connected to the outer wall of the lever 42, the outer wall of the movable shaft 43 at the lower end of the lever 42 is installed with a connecting rod 52, one end of the connecting rod 52 is installed with a movable plate 53, the inner wall of the movable plate 53 is installed with multiple ultrasonic transducers 54, and one end of the connecting rod 52 is installed with a conductive rod 55. The inner bottom wall of the adjusting box 40 is installed with an adjusting shaft 6, the outer wall of the adjusting shaft 6 is installed with a buffer plate 61, the outer wall of the buffer plate 61 is installed with a conductive plate 62, the outer wall of the buffer plate 61 is installed with a first spring 63, and one end of the first spring 63 is fixedly connected to the inner bottom wall of the adjusting box 40.

[0042] Specifically, when the bed wheelchair moves to the middle position of the water tank 1, the electric telescopic rod 5 extends and drives the lever 42 to rotate, so that the upper end of the lever 42 rotates toward the water tank 1. At this time, the lever 42 pushes the pad 44 out of the fixing hole 45. The pad 44 extends, and one end of the bed wheelchair moves onto the pad 44 and blocks the bed wheelchair. At this time, since the bearing plate 23 continues to rotate, the cleaning brush 24 on the bearing plate 23 brushes the backrest and seat cushion of the bed wheelchair during the movement process, and cleans the backrest and seat cushion.

[0043] It should be noted that, during the above-mentioned scrubbing process, the lower end portion of the lever 42 moves toward the outside of the adjustment box 40. At this time, the conductive rod 55 moves and contacts the conductive plate 62, and the conductive plate 62 is tightly attached to the conductive rod 55. At this time, the first spring 63 drives the buffer plate 61 and the conductive plate 62 to be tightly attached to the conductive rod 55, thereby ensuring the connectivity of the circuit. After the circuit is connected, the ultrasonic transducer 54 works. At this time, the cleaning brush 24 after scrubbing rotates to the bottom of the sink 1. The ultrasonic transducer 54 works to shake off the dirt attached to the cleaning brush 24, so that the cleaning brush 24 remains clean when scrubbing the backrest and seat cushion of the bed wheelchair again, thereby preventing the cleaning brush 24 from being dirty and causing incomplete scrubbing.

[0044] See also Figure 5 、 Figure 7 and Figure 8A cleaning pipe 9 is installed at the bottom of the fixed box 70, and one end of the cleaning pipe 9 is connected to one end of the air injection pipe 72. A regulating valve 91 is installed on the outer wall of the cleaning pipe 9. An regulating rod 92 is installed through the outer wall of the regulating valve 91. A third spring 93 is installed around the outer wall of the regulating rod 92. An extrusion block 94 is installed at one end of the regulating rod 92. A sealing block 95 is installed at the bottom of the regulating rod 92. A sealing plate 96 is installed on the inner wall of the regulating valve 91, and a through hole 97 is opened in the middle position of the sealing plate 96.

[0045] Specifically, when the electromagnetic heating coil 82 heats the hair on the axle by heating, there will be ashes after the hair burns. At this time, the lifting rod 8 is in a descending state, and the extrusion rod 84 is in contact with the extrusion block 94. The movement of the extrusion block 94 drives the adjustment rod 92 to move, and the movement of the adjustment rod 92 drives the third spring 93 to extend and retract. The movement of the adjustment rod 92 drives the sealing block 95 to move, and the sealing block 95 moves and separates from the through hole 97, so that the air in the fan 71 is ejected through the jet pipe 72 and the cleaning pipe 9, so that the ashes after the hair burns are blown away, thereby realizing the cleaning function of the hair entangled on the axle.

[0046] Working principle: first adjust the bed wheelchair to the posture of the bed so that the backrest and seat cushion are in the same plane, then place one side of the backrest and seat cushion on the load-bearing plate 23, then start the drive motor 2, the drive motor 2 rotates to drive the transmission shaft 21 to rotate, the transmission shaft 21 drives the chain 22 and multiple load-bearing plates 23 to rotate, thereby driving the bed wheelchair to move toward the inside of the water tank 1, at the same time the flushing water pump 3 and the second water pump 31 work to extract the disinfectant in the storage tank 32, and flush it downward through the flushing nozzle 34 to clean and disinfect the back of the bed wheelchair and the axle frame, then when the bed wheelchair moves to the middle position of the water tank 1, the electric telescopic rod 5 extends to drive the lever 42 to rotate, so that the upper end of the lever 42 rotates toward the direction of the water tank 1, at this time the lever 42 pushes the pad 44 to extend from the fixing hole 45, the pad 44 extends, and at this time one end of the bed wheelchair moves onto the pad 44 and blocks the bed wheelchair, at this time by As the load-bearing plate 23 continues to rotate, the cleaning brush 24 on the load-bearing plate 23 brushes the backrest and seat cushion of the bed wheelchair during its movement, and cleans the backrest and seat cushion. Then, when the backrest and armrests of the bed wheelchair are cleaned, the wheels and frame of the bed wheelchair move to the outlet of the water tank 1. At this time, the first motor 73 rotates to drive the rotating shaft 75 to rotate, and the rotation of the rotating shaft 75 drives the impact rod 74 to rotate. The rotation of the impact rod 74 will squeeze the impact plate 81, and the impact plate 81 will drop after being squeezed, and the lifting rod 8 will drop accordingly. The lifting rod 8 drops and drives the electromagnetic heating coil 82 to drop. At this time, the electromagnetic heating coil 82 drops. At this time, the electromagnetic heating coil 82 covers the wheel axle part. The electromagnetic heating coil 82 is energized and dissipates heat, which quickly increases the temperature of the wheel axle part, so that the temperature of the wheel axle part quickly reaches hundreds of degrees Celsius, thereby heating the hair wrapped around the wheel axle so that the hair can be ignited, thereby achieving the hair cleaning function.
