[0063] When performing window wiping and mopping operations, the initial state of the present invention is that the air purification module 6 is connected to the assistant module 5 through an electromagnet, and the assistant module 5 is connected to the sweeping and window wiping module 4 through an electromagnet, and the combination of the three is stored in a highly automated base station, and the first loading platform 9 is located at a slot 50 reserved between the sweeping and window wiping module 4 and the assistant module 5; first, the electromagnets that attract each other between the sweeping and window wiping module 4 and the assistant module 5 are powered off, so that the two are in an active connection state, and then the module loading and unloading motor in the highly automated base station is operated to drive the module loading and unloading ball screw to rotate, thereby driving the module loading and unloading slider coaxially connected to the module loading and unloading ball screw, and since the module loading and unloading slider is movably connected to the first shell 1, The former can only move along the axial direction of the module loading and unloading ball screw. The module loading and unloading slider moves to the left along the axial direction of the module loading and unloading ball screw, driving the first scissor rod lifting assembly 8 to move upward, driving the first loading platform 9 and the assisting module 5 and the air purification module 6 loaded thereon to move upward. After separating from the sweeping and window wiping module 4, the module loading and unloading motor stops working, and then the self-cleaning motor 94 works, and drives the self-cleaning scrapers coaxially connected thereto to work, and perform fan-shaped reciprocating motion inside the first shell 1 to perform the self-cleaning work of the rag 31. After completing the self-cleaning work, the self-cleaning motor 94 stops working, and the rag disassembly motor 71 works, driving the two sets of front disassembly ball screws coaxially connected thereto to rotate, and then driving the two sets of rags The second loading platform 38 coaxially connected to the ball screw 72 for rag removal moves. Since the second loading platform 38 is movably connected to the first shell 1 through a slot, the second loading platform 38 can move up and down along the axis of the ball screw 72 for rag removal. After the second loading platform 38 reaches a height flush with the horizontal plane where the sweeping and window wiping module 4 is stored, the motor 71 for rag removal stops working. At this time, the two sets of doors 2 coaxially connected to the upper door 201 and the lower door 202 are started with micro motors to drive the upper door 201 and the lower door 202 to expand outwards respectively. When the two are expanded to the target angle, the micro motor for door 2 stops working; the crawler lifting motor starts working to drive the crawler lifting ball screw coaxially connected thereto to rotate, and the crawler lifting motor starts working. The crawler lifting slider drives the second scissor rod lifting assembly 27 to produce an upward displacement, drives the components above the first chassis 29 to lift, and realizes the lifting of the chassis height. After lifting to the target height, the crawler lifting motor stops working; the first motor 57 starts to work, and drives the small pulley 44 coaxially connected thereto to rotate, and the latter drives the left and right groups of large pulleys 42 coaxially connected to the reserved shaft of the first chassis 29 through the transmission belt 43, and the two groups of large pulleys 42 drive the driving wheel 41 coaxially connected thereto, and the driving wheel 41 drives the crawler 24 meshed with the plate hole therewith to realize the traveling function, and the sweeping and window wiping module 4 uses the lower hatch 202 in contact with the ground as the road to leave the highly automated base station. After reaching the target location, the first motor 57 stops working;The crawler lifting motor starts to work, and the working principle is opposite to the above chassis height lifting, so that the chassis height is lowered. After the rag 31 touches the ground, the crawler lifting motor stops working, and the first motor 57 starts working to perform the cleaning task; Before sweeping the floor, the sweeping and window wiping module 4 in the mopping function state needs to return to the highly automated base station. The principle is the same as that of the sweeping and window wiping module 4 leaving the cabin. After returning, the rag removal motor 71 is started, driving the two sets of rag removal ball screws 72 coaxially connected thereto, and then driving the second loading platform 38 coaxially connected to the latter, which produces axial movement under the constraint of the reserved card slot of the first shell 1. When the second loading platform 38 reaches a height flush with the horizontal plane where the sweeping and window wiping module 4 is stored, the rag removal motor 71 stops working. At this time, in the sweeping and window wiping module 4, the connection between the rag 31 and the dust cabin 30 is The electromagnet is powered off, loses its magnetism, and falls off to the second loading platform 38 received below. At this time, the dust compartment 30 is exposed, and the rag removal motor 71 works again. After the second loading platform 38 lifts the front rag 31 to a height flush with the horizontal surface of the sweeping and window wiping module 4, the rag removal motor 71 stops working, and the first motor 57 starts working. The sweeping and window wiping module 4 drives away from the highly automated base station and starts vacuuming and sweeping. At this time, the air inlet and outlet grilles 14 are fully opened, and the multifunctional fan starts to work at a relatively low power when adsorbing windows, realizing the vacuuming and sweeping function. The working principles of the remaining components are the same as those when mopping the floor and wiping windows. Before air purification and assisting the elderly, it is necessary to install some components based on the mopping and window cleaning functions mentioned above to achieve the following: The sweeping and window wiping module 4 in the mopping function state needs to return to the highly automated base station. The principle is the same as that of the sweeping and window wiping module 4 leaving the cabin. When the sweeping and window wiping module 4 reaches the target location, the first motor 57 stops working, and the module loading and unloading motor starts, driving the module loading and unloading ball screw coaxially connected thereto to rotate, driving the first scissor-bar lifting assembly 8, so that the first loading platform 9 is displaced downward, and the first loading platform 9 and the supporting module 5 and the air purification module 6 loaded thereon descend. When the third chassis 45 is connected to the second shell 12 through the reserved slot, the module loading and unloading motor stops working, and at the same time, the electromagnet is energized. The reserved electromagnets inside the two are connected by opposite attraction, and the supporting module 5, the air purification module 6 and the sweeping and window wiping module 4 form a combination; the first motor 57 starts working, and the combination drives out of the highly automated base station; During the working of the hand-assisting device, the second motor 73 starts to work first, driving the hand-assisting device transmission shaft 77 coaxially connected thereto to rotate, and the power is transmitted from the hand-assisting device transmission shaft 77 to the first cylindrical gear 76 coaxially connected thereto, and the first cylindrical gear 76 and the second cylindrical gear 80 mesh to transfer the power to the first hand-assisting device ball screw 78 coaxially connected to the second cylindrical gear 80, and the first hand-assisting device ball screw 78 in turn drives the first bevel gear 79 coaxially connected thereto, and the first bevel gear 79 is driven by the first cylindrical gear 76. The gear 79 meshes with the second bevel gear 75, and the second bevel gear 75 meshes with the third bevel gear 74, which drives the third ball screw 96 for supporting people coaxially connected thereto to rotate, and the third ball screw 96 for supporting people drives the third slider 99 for supporting people to move axially along the third ball screw 96 for supporting people, driving the third scissor rod lifting assembly 47 to produce an upward displacement, so that the supporting platform 48 maintains a vertical upward displacement. When the target height is reached, the second motor 73 stops working to realize the supporting function; In the air purification work, the air inlet and outlet fans 90 start working first, passing the air from the lower air inlet through the first filter element 86, the second filter element 87, and the third filter element 88 in sequence, and then entering the air purification chamber 89. After purification, the air is discharged from the upper air outlet. In the humidification work, the humidification fan 83 starts working first, and the internal atomizer of the humidification water tank 84 discharges the water vapor through the humidification fan 83, thereby achieving the air purification and humidification functions. During the automatic exit of the dust chamber 30, the sweeping and window wiping module 4 needs to return to the highly automated base station. The principle is the same as that of the sweeping and window wiping module 4 exiting the chamber above. When the sweeping and window wiping module 4 reaches the destination, the rag disassembly motor 71 is started, driving two sets of rag disassembly ball screws 72 coaxially connected thereto, and then driving the second loading platform 38 coaxially connected thereto, which generates axial movement under the constraint of the reserved card slot in the first shell 1. When the rag 31 disassembly platform reaches a height flush with the horizontal plane where the sweeping and window wiping module 4 is stored, the rag disassembly motor 71 stops working. At this time, in the sweeping and window wiping module 4, the dust chamber 30 is unloaded. The electromagnet connected to the second shell 12 is powered off, loses its magnetism, and falls off to the front disassembly platform below. The rag disassembly motor 71 starts working again. After the second loading platform 38 lifts the dust bin 30 to a height flush with the horizontal plane of the slider 59 for exiting the bin, the rag disassembly motor 71 stops working, and the door 2 coaxially connected to the dust bin door 203 is started with a micro motor. After driving the dust bin door 203 to expand outward, the door 2 is closed with a micro motor, and the fifth screw motor module is actuated. At this time, the slider 59 for exiting the bin uses its upper push rod 56 to push the dust bin 30 out of the highly automated base station, thereby realizing the automatic exit function of the dust bin 30.
