[0023] As Figures 1 to 6 shown, a front-suction and rear-mopping cleaning system of a floor washer includes a housing assembly 1, a roller 2, a wiper blade 3, a filter chamber 4, a filter screen 5, a suction port 6, a sewage channel 7, a sewage tank 8, and a blower 9. The roller 2, the wiper blade 3, and the filter chamber 4 are installed at the bottom of the housing assembly 1. The wiper blade 3 is close to the roller 2, and the wiper blade 3 scrapes off the sewage on the roller 2. The sewage enters the filter chamber 4. The filter screen 5 is installed inside the filter chamber 4. The filter screen 5 is provided with mesh holes for intercepting large-particle contaminants. The suction port 6 is arranged at the bottom of the housing assembly 1, with the suction port 6 in the front and the roller 2 in the rear. A dust suction air duct 10 is arranged inside the housing assembly 1. The dust suction air duct 10 is connected to the filter chamber 4. The filter chamber 4 is communicated with the sewage tank 8 through the sewage channel 7. The blower 9 generates suction in the sewage channel 7 to suck dry garbage and sewage.

[0024] As Figure 6 shown, a transition channel 11 is arranged between the dust suction air duct 10 and the filter chamber 4. A water inlet 12 is arranged on one side of the transition channel 11 close to the roller. A water receiving piece 13 is installed at the water inlet 12. When the internal machine operates, a negative pressure is formed above the roller 2 at the position of the water inlet 12, sucking the garbage and sewage on the roller into the filter screen box, with strong sewage collection ability. The sewage filtered by the filter screen 5 is collected in the sewage tank.

[0025] As Figures 5 to 7 shown, the housing assembly 1 includes an upper shell 14, a middle plate 15, and a bottom shell 16. The middle plate 15 is installed at the bottom of the upper shell 14. The dust suction air duct 10 is formed between the upper shell 14 and the middle plate 15. The bottom shell 16 is covered below the upper shell 14. The roller 2 is installed on the bottom shell 16. A dust suction nozzle 17 is installed inside the bottom shell 16. The dust suction nozzle 17 is located in front of the roller 2. The suction port 6 is arranged at the dust suction nozzle 17. The dust suction nozzle 17 is connected to the dust suction air duct 10. Dry garbage enters the dust suction nozzle 17 from the suction port 6, and then reaches the filter chamber 4 through the dust suction air duct 10 and the transition channel 11.

[0026] Specifically, a roller accessory mounting plate 18 is installed below the middle plate 15. A water blocking strip 19, a wiper blade 3, a water spraying port 20, and a tooth comb 21 are installed in the roller accessory mounting plate 18 in sequence from front to back. These are all common part designs in the floor washer roller system.

[0027] Specifically, the filtration chamber 4 is arranged in the bottom shell 16. The filtration chamber 4 is located behind the drum 2. An outlet is provided on the side of the filtration chamber 4, and the outlet is connected to the sewage channel 7 through a pipe joint so that the filtered water can pass through.

[0028] Specifically, a central pipe 22 is arranged in the sewage tank 8. The central pipe 22 is connected to the sewage channel 7. The upper opening of the central pipe 22 is higher than the bottom surface of the sewage tank 8. A blower 9 is installed above the sewage tank 8. A filter cotton 23 is arranged between the blower 9 and the sewage tank 8. An exhaust duct 24 is installed behind the blower 9. Floor garbage is sucked in from the suction port, passes through the dust suction air duct, large particles fall into the filter screen box, small particles enter the sewage tank through the sewage channel and are intercepted by the filter cotton 23 upward and will not fall to the bottom.

[0029] The advantages of the present utility model are as follows;

[0030] (1) The front-suction and rear-drag cleaning system of the present utility model adopts a structure with the suction port in the front and the drum in the rear, so that dry garbage is sucked into the filter screen box through the suction port before contacting the drum, avoiding the influence of dry garbage on the rear drum mopping. The drum mopping can clean the ground more deeply, realizing the separation of dry and wet and improving the cleaning performance of the cleaning system;

[0031] (2) The drum rotates forward and rubs against the ground, bringing the ground garbage and sewage to the water receiving piece. The particulate matter is combed down by the tooth comb and sucked into the filter screen box by the negative pressure generated by the air duct. At the same time, clean water is sprayed out from the water spraying port to clean the drum, and the water scraping piece scrapes off the dirty water, which flows down through the water receiving piece, ensuring the cleanliness and dryness of the drum. The dirty water is sucked into the sewage tank through the pipeline, and the cleaning ability of the drum is strong;

[0032] (3) Floor garbage is sucked in from the suction port, passes through the dust suction air duct, large particles fall into the filter screen box, small particles enter the sewage tank through the sewage channel, and the front-suction ability is strong;

[0033] (4) When the blower operates, a negative pressure will be formed above the drum at the opening position, sucking the garbage and sewage on the drum into the filter screen box to effectively clean the drum.

[0034] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope of the present utility model.
