Background technique

The floor washing machine is a cleaning machine suitable for cleaning hard floors, simultaneously sucking up sewage, and taking the sewage away from the site. The working principle of the floor washing machine is that during the cleaning process, the drum rotates and cleans, and at the same time, the sewage, dust, sundries, etc. are sucked into the sewage tank through the suction motor.

The clean water tank and the dirty water tank of the existing floor washing machine are independent and separated, and the two usually adopt a front-to-back/left-to-right layout or a stacked layout, but both have many defects. For the front-to-back/side-by-side layout, the center of gravity of the machine will change during the use of the water tank. Gradually offset to the side of the sewage tank, resulting in a decrease in the walking accuracy of the floor washing machine. In addition, this layout will make the horizontal cross-sectional area of the sewage tank smaller. In order to meet the capacity demand, the height of the sewage tank has to be increased, resulting in an increase in the height of the whole machine; For the layout of the upper and lower layers, the insufficient water vapor separation height will be sacrificed. In the case of the same total height, the water vapor separation will be more difficult. Due to the influence of the height of the machine shape, the water vapor separation height distance is not enough. The power of the sewage recovery fan is small, resulting in insufficient sewage recovery and easy residual water stains.

Rotate at a certain speed, and the drum 8 wetted by clear water can clean the ground, use the centrifugal force to throw out the sewage adsorbed on the material of the drum 8 or squeeze out the water adsorbed on the drum 8 by setting a water squeezing plate, and start the suction at the same time The air device 10 works synchronously, a negative pressure will be formed in the first water tank 1 and the channel 9, and a part of the sewage on the drum 8 and most of the sewage leaving the drum 8 will be sucked into the first water tank 1 to complete the cleaning. For the recovery of sewage, the water level in the second water tank 2 will gradually decrease with consumption, and the water level in the main body 102 of the first water tank 1 will gradually rise with the recovery of sewage. In the vertical direction, the center of gravity of the cleaning equipment is in the cleaning process. will gradually decrease, and because the raised portion 101 protrudes from the top surface of the main body portion 102, the main body portion 102 has a larger cross-sectional area relative to the raised portion 101, while ensuring a certain sewage capacity Simultaneously, along with the accumulation of sewage in the main body 102, the overall center of gravity of the water tank assembly will gradually move down to the main body 102 with a larger cross-sectional area, which can make the overall center of gravity of the water tank assembly relatively stable. When the structural design of the water tank assembly is symmetrical When the structure is used, the center of gravity of the water tank assembly during use can only have a small deviation or no deviation in the horizontal direction. It can be seen that, at different stages of the cleaning equipment, the overall center of gravity will continue to shift in the vertical direction along with the cleaning process, and the overall center of gravity will basically remain unchanged in the horizontal direction or only have a certain deviation within a preset range. shift, thus realizing the stability of the overall structure during use.
