It can be understood that an insulating layer is arranged between the supporting block 32 and the heating plate 33, and the insulating layer is made of high-temperature-resistant insulating material, so that the temperature of the supporting block 32 and the temperature of the heating plate 33 are prevented from being synchronously increased, and the service life of the supporting block 32 is shortened. The scraper 233 is fixedly disposed in the protective case 232 through a bracket, and one side of the scraper 233 presses the rolling brush 231, when the floor washing machine 2 cleans the floor, the sewage adsorbed by the rolling brush 231 is scraped off through the scraper 233, and meanwhile, the sewage on the floor is collected through the push plate 234, so that the scraper 233, the push plate 234 and the rolling brush 231 surround to form a sewage collecting area, and the sewage in the sewage collecting area is sucked into the sewage tank 223 through the negative pressure generated by the air pump 221, and meanwhile, the purified water in the purified water tank 222 is sprayed to the rolling brush 231 through the purified water pipe. By spraying purified water after continuously scraping off the sewage on the rolling brush 231, the rolling brush 231 can clean the ground and simultaneously perform self-cleaning, so that a large amount of dirt is prevented from remaining in the rolling brush 231.
Specifically, the water tank 22 is provided with a water purifying tank 222 and a sewage tank 223, the bottom of the water purifying tank 222 is connected with one end of a water purifying pipe, the other end of the water purifying pipe is provided with a spray head 235, the spray head 235 is fixed on the top of a scraper 233 of a 2362, the spray head 235 is provided with more than 2 nozzles 2351, the water purifying pipe is provided with a water pump 237, and the purified water pressurized by the water pump 237 is uniformly sprayed to the roller brush 231 from the nozzles 2351; the bottom of the sewage tank 223 is connected with the outlet end of the sewage pipe 239, the inlet end of the sewage pipe 239 corresponds to the push plate 234, the protective shell 232 and the rolling brush 231 surround a sewage collecting area, and the sewage tank 223 pushes the push plate 234 to scrape sewage collected on the ground through negative pressure generated by the air pump 221 arranged in the inner cavity of the sewage tank 223 and then sucks the sewage into the sewage tank 223 through the inlet end.
It will be appreciated that the separate arrangement of the clean water tank 222 and the foul water tank 223 in the tank 22 allows the roll brush 231 to clean the floor with clean water while operating, and allows the foul water tank 223 and the foul water pipe 239 to generate negative pressure by the operation of the air pump 221 to suck the foul water on the floor into the foul water tank 223. Avoid the clean ground of used repeatedly sewage, reduce the efficiency of clean ground.
It can be understood that water purification pipe interlude is equipped with water pump 237, sets up through water pump 237 pressurization, can more efficient wash round brush 231, avoids causing the waste of water purification.
Further, the size of the spray head 235 corresponds to the size of the rolling brush 231, and the spray head 235 is provided with a plurality of nozzles 2351, so that purified water can be uniformly sprayed onto the rolling brush 231, and the problem that the purified water cannot be uniformly sprayed onto the rolling brush 231 when a single practical nozzle 2351 is used for spraying is avoided.
Specifically, tooth case subassembly 236 includes motor 2361, gear train 2363 and fixing base 2362, and gear train 2363 arranges fixing base 2362 inner chamber in, and gear train 2363 is equipped with more than 2 gears, and the rotor of motor 2361 is connected with the gear meshing of gear train 2363 one end, and the gear and the round brush 231 meshing of the gear train 2363 other end are connected.
It can be understood that the motor 2361 is transmitted to the rolling brush 231 through the gear train 2363, and the gear meshed with the rotor of the motor 2361 is smaller than the gear meshed with the rolling brush 231, so that the ground cleaning frequency of the rolling brush 231 is increased by the arrangement.
Further, when the floor washing machine 2 cleans the ground, the rotating speed range of the rolling brush 231 is 500r/min-600r/min, and when the floor washing machine 2 cleans the floor, the rotating speed range of the rolling brush 231 is 30r/min-50r/min.
