[0026] Referring to Figures 1 to 6 , a floor scrubber with a floor drying function includes a main unit 1 and a floor brush 2 pivotally connected to the bottom of the main unit 1. The floor brush 2 includes a floor brush housing 21 and a floor scrubbing roller 22 that is rotatably mounted at the front end of the floor brush 2. The floor brush housing 21 is provided with a suction port 24 behind the floor scrubbing roller 22. The main unit 1 is provided with a suction motor 3 having an air intake 31 and an air outlet 32. A suction channel 5 is provided between the floor brush 2 and the main unit 1, connecting the suction port 24 with the air intake 31 of the suction motor 3. The floor brush is also provided with a water spray port to supply water to moisten the floor scrubbing roller 22 and the floor. The floor scrubbing roller 22 rolls to wipe dirt from the floor and simultaneously picks up floor debris, which is then sucked into the main unit through the suction port 24 for temporary storage along with the wastewater generated by floor scrubbing. A blowing port 25 is provided at the bottom of the floor brush housing 21. The blowing port 25 is arranged behind the floor scrubbing roller brush 22 along the forward direction of the floor brush 2. A blowing channel 6 is also arranged between the floor brush 2 and the main unit 1. The blowing channel 6 connects the blowing port 25 and the air outlet 32 ​​of the suction motor 3. The wind blown out from the air outlet 32 ​​of the suction motor 3 is guided by the blowing channel 6 to the blowing port 25 at the bottom of the floor brush 2 and blown toward the ground. The blowing port 25 blows air close to the ground, and the air drying efficiency is higher. The water stains on the cleaned ground can be further dried quickly after blowing, so as to avoid the situation where the ground with water stains after cleaning is repeatedly stepped on and becomes dirty again or the user slips; and the blowing port 25 reasonably utilizes the air outlet of the suction motor 3 as the air source, and guides the air outlet of the suction motor 3 to the blowing port 25 at the bottom of the floor brush through the arrangement of the blowing duct 9. There is no need to set up a separate fan for blowing, which effectively saves costs.

[0027] As shown, in this embodiment, the main unit 1 includes a housing 11, a dirt tank 7, and a suction motor 3. The housing 11 is formed with a mounting compartment 12 for mounting the dirt tank 7 and a housing 13 for housing the suction motor 3. Specifically, the housing 11 includes a front housing 111 and a rear housing 112. The mounting compartment 12 and housing 13 are formed on the front housing 111. The rear housing 112 is positioned behind the front housing 111 and houses the mounting compartment 12 and housing 13. The air duct 6 is formed by the air duct 9 and is disposed between the front and rear housings 111 and 112.

[0028] The accommodating chamber 13 and the mounting chamber 12 are spaced apart from each other, and a docking port 14 is provided on the wall separating them. After the suction motor 3 is installed in the accommodating chamber 13, its air intake 31 is sealedly engaged with the docking port 14. A suction port 15 is provided on the bottom wall of the mounting chamber 12, and a suction duct 8 is provided to the suction port 15 to communicate with the suction port 24 on the floor brush housing 21. The dirt box 7 is provided with a dirt inlet 71 and a ventilation outlet 72. The body shell 11 is provided with an installation opening 121 for the dirt box 7 to be installed in the installation chamber 12. After the dirt box 7 is installed in the installation chamber 12 through the installation hatch 12, the ventilation outlet 72 is docked with the docking port 14 and is sealed and connected with the suction port 31 of the suction motor 3 through the docking port 14. The dirt inlet 71 is docked with the suction port 15, so that the dirt box 7 is connected with the suction pipe 8 to form the suction channel 5. The garbage and sewage sucked into the suction port enter the dirt box 7 through the suction pipe 8. A filtering structure is provided at the ventilation outlet 72 of the dirt box 7 to temporarily store the sewage and garbage in the dirt box 7.

[0029] An exhaust port 16 is also provided on the wall of the accommodating chamber 13. The accommodating chamber 13 is formed by a sealing cover provided on the back of the front shell 111 of the mounting chamber 12. A docking port 14 is formed on the top wall of the mounting chamber 12. After the suction motor 3 is installed in the accommodating chamber 13, its air outlet 32 ​​is connected to the exhaust port 16, and the blowing channel 6 is docked and connected to the exhaust port 16. Specifically, the blowing duct 9 includes a vertical pipe portion 91 extending downward from the exhaust port 16 of the accommodating chamber 13, and a curved pipe portion 92 connected to the bottom end of the vertical pipe portion 91 and winding through the floor brush housing 21 to communicate with the blowing port 25. The curved pipe portion 92 is made of a flexible material or partially made of a flexible material, so that the curved pipe portion 92 can be bent and extended from the main unit into the floor brush housing 21 to communicate with the blowing port 25, and can also cooperate with the pivotal movement between the main unit 1 and the floor brush 2.

[0030] As a preferred embodiment of the present invention, the air outlet 25 is a strip-shaped air outlet and is arranged from left to right across the bottom of the floor brush housing 21 and parallel to the mopping roller brush 22. The strip-shaped air outlet realizes fan-shaped air discharge to quickly dry the floor wiped by the mopping roller brush 22 to the greatest extent possible. Specifically, the air outlet 25 is formed by a strip-shaped trough 26 on the bottom surface of the floor brush housing 21. A vent is provided in the middle of the strip-shaped trough 26 that interfaces with the air blowing channel 6, so that the fan 3 is connected to the middle of the air outlet 25. The air blown by the fan 3 first enters the strip-shaped trough 26 and fills the entire strip-shaped trough 26 under the guidance of the wall surface of the strip-shaped trough 26, and then is discharged as a whole from the air outlet 25.

[0031] As a preferred embodiment, a floor scraping strip 4 is further installed at the bottom of the floor brush housing 21. The floor scraping strip 4 is arranged across the bottom of the floor brush housing 21 and is arranged parallel to the floor scrubbing roller brush 22, and is arranged between the air outlet 25 and the floor scrubbing roller brush 22. When the floor scrubbing roller brush 22 finishes wiping the floor, the floor scraping strip 4 first scrapes the cleaned floor, scraping up some water stains and sucking them away through the suction port 24. The remaining water stains on the floor are then blown out of the air outlet 25 at the rear to quickly dry the floor, achieving a better drying effect. On the other hand, the floor scraping strip 4 can block the air from the air outlet 25 from blowing onto the floor scrubbing roller brush 22, preventing the air flow from affecting the floor scrubbing effect of the floor scrubbing roller brush 22. Specifically, the floor scraper 4 includes a mounting plate 41 and a silicone scraper 42. The bottom surface of the floor brush housing 21 is provided with a mounting groove for the mounting plate 41 to be embedded. The silicone scraper 42 is arranged behind the floor scrubbing roller brush 22 and is smoothly connected to the bottom surface of the suction port 24 of the floor brush 2 toward the surface of the floor scrubbing roller brush 22, so that the scraped water stains can enter the suction port 24 more conveniently along the surface of the silicone scraper 42. The silicone scraper 42 can fit tightly to the ground to form a sealing effect, which can further enhance the suction effect of the suction port 24.

[0032] As a preferred solution, a heating element can be arranged on the blowing duct 9 so that the blowing port 25 can blow out hot air. The hot air can complete the drying work more quickly, and the hot air also has a certain disinfecting effect.
