The working process and principle are as follows: in the use process of the invention, firstly, an operator stands on the ground and controls the lifting power source 2 to start through a control lever, the air flow lifting action drives the robot to rise to a lighting ceiling to be cleaned, under the action of negative pressure, the sponge cleaning layer 518 is tightly attached to the surface of the ceiling, then the heating exhaust pipe 408 is opened to enable the robot to be in a high-temperature state, the micro water pump 405, the throttle valve 407 and the steering engine 501 are simultaneously opened, so that water stored in the water storage tank 401 is driven by the micro water pump 405 to enter the steam heating tank 421 along the water outlet pipe 406, moisture flowing onto the bottom plate of the steam heating tank 421 is quickly vaporized to form high-temperature steam, the high-temperature steam passes through the high-temperature resistant flexible connecting pipe 422, the steam blowing part 402 and the obliquely arranged air hole two 418 to generate a certain amount of steam and then the throttle valve 407 is closed, the heating exhaust pipe 408 further heats the steam, and the whole temperature of the steam blowing part 402 is quickly raised after the steam is guided through the flexible connecting pipe 422, after flowing through the second air hole 418, the airflow is blown to the roller 404 to continuously rotate, the airflow enters the roller 404 through the first air hole 417, meanwhile, because no opening is formed in the groove 416, high-temperature airflow flows into the tee cavity 514 on the roller 404 in an intermittent supply mode, and is cooled through the air inlet pipe 513 to be supplied into the uppermost brush head 503, the temperature of the airflow is relatively weakened at the moment, the surface to be cleaned is prevented from being damaged by high temperature, the cleaning agent is in an active state after the temperature is mixed with the cleaning agent in the liquid storage box 504, the maximum cleaning capability is exerted, meanwhile, the output end of the steering engine 501 drives the swing rod 510 to swing around a hinge point at the lower end through the rocker 508 and the slider 509, and the connecting rod 506 drives the sponge cleaning layer 518 on the brush head 503 to perform reciprocating cleaning on the surface of a lighting ceiling;

in the process, sewage generated after cleaning flows into the dust exhaust cover 409 through the lower port of the sewage discharge pipe 512 and falls onto the rotating frame 403, heat on the steam blowing part 402 is transferred onto the rotating frame 403 through the heat conduction shaft 411, the rotating frame 403 with higher temperature enables the sewage deposited thereon to be rapidly evaporated, high-temperature steam circularly enters the three-way cavity 514 to realize the reuse of the sewage, then along with the continuous increase of deposition amount, the lower end of the rotating frame 403 can push the top ball 414 to slide rightwards, so that the spring I415 is in a compression state, when the deposition amount reaches a certain amount, the lower end of the rotating frame 403 is separated from the top ball 414 and rotates, the volatilized dust falls into the dust collection groove 519 along the inclined plane of the fixed seat 410, the effective collection of dry dust is completed, the phenomenon that dirty liquid generated after high-altitude cleaning splashes on the side wall of the environment is avoided, along with the circular rotation of the rotating frame 403, the connecting rod 413 drives the piston 412 to slide back and forth in the steam blowing part 402, under the sealing action of the sealing plate 419, the internal air flow of the steam blowing part 402 is intermittently discharged, so that the intermittent air flow is synchronously formed at the cleaning end of the sponge cleaning layer 518, the effect of effectively removing stubborn stains on the ceiling is realized, and after the one-way cleaning process is finished, the propelling power source 3 at the other side is started to control the advancing direction of the robot, so that the comprehensive cleaning of the ceiling is finished;

when the size of the surface to be cleaned of the ceiling is changed, the swing angle of the sponge cleaning layer 518 can be changed by only adjusting the mounting positions of the steering engine 501 on the different bearing seat holes 507 of the fixing frame 502, so that the ceiling of any size can be cleaned, the liquid storage box 504 can be lifted at will within the adjustable range of the second spring 511, and meanwhile, the extensible recovery capability of the sponge cleaning layer 518 is combined, so that the ceiling of any radian within a certain range can be effectively cleaned;

when meetting ceiling girder steel joint, the sponge cleaning layer 518 of brush head 503 upper end can carry out the cladding to the both sides of joint department girder steel, drives both sides simultaneously and bonds in the rotation of the side brush piece 517 under the sponge cleaning layer 518, and then effectively cleans the both sides of joint department girder steel.

Based on the above, the steam supply mechanism 4 and the cleaning mechanism 5 are arranged in the main body 1, the sponge cleaning layer 518 is tightly attached to the surface of the ceiling under the action of the jacking negative pressure of the lifting power source 2, meanwhile, high-temperature steam is intermittently supplied into the rotating roller 404 from the steam blowing part 402, the temperature is controlled in a relatively weakened appropriate range in the process of prior vaporization and re-liquefaction of water, and the sponge cleaning layer 518 on the brush head 503 is combined with active detergent to automatically and efficiently clean the surface of the ceiling in a reciprocating manner;

through the quantitative screening of the high-temperature rotating frame 403, the sewage deposited on the high-temperature rotating frame 403 is rapidly evaporated, high-temperature steam circularly enters the three-way cavity 514, the water in the sewage can be reused, and finally only dry dust can be collected, so that the phenomenon that dirty liquid generated after high-altitude cleaning is splashed on the side wall of the environment is avoided, meanwhile, the rotating frame 403 circularly rotates and drives the piston 412 to slide in the steam blowing part 402 in a reciprocating manner through the connecting rod 413, under the sealing action of the sealing plate 419, the internal airflow of the steam blowing part 402 is intermittently discharged, and further, the cleaning end of the sponge cleaning layer 518 synchronously forms intermittent airflow, and the effect of effectively removing stubborn stains on a ceiling is realized;

the swing angle of the sponge cleaning layer 518 can be changed by adjusting the mounting positions of the steering engine 501 on the fixing frame 502 on different bearing seat holes 507, so that the ceiling of any size can be cleaned, the liquid storage box 504 can be lifted at will within the adjustable range of the second spring 511, and simultaneously, in combination with the extensible recovery capability of the sponge cleaning layer 518,

and further, the ceiling with any radian in a certain range can be effectively cleaned.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
