[0026] Referring to Figures 1 to 6, a floor scrubber with a blowing 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 brush 22 that is rollingly installed at the front end of the floor brush 2. A suction channel 23 is provided inside the floor brush housing 21 to connect to the main unit 1, and a suction port 24 to connect to the suction channel 23 is arranged behind the floor scrubbing roller brush 22. A suction motor 7 and a sewage bucket are provided on the main unit 1. The suction motor 7 is connected to the suction port 24 through the sewage bucket, and water is supplied to the floor scrubbing roller brush 22 and the ground through the water spray port. The floor scrubbing roller brush 22 rolls to wipe the dirt on the ground and at the same time rolls up the garbage on the ground and connects to the sewage formed by wiping the floor, which is sucked into the sewage bucket by the suction port 24 for temporary storage. The bottom of the floor brush housing 21 is provided with an air outlet 25, which is arranged behind the floor scrubbing roller brush 22 along the forward direction of the floor brush 2. The air outlet 25 is connected to the fan 3 arranged on the main unit 1 or the floor brush 2, and the fan 3 blows air through the air outlet 25 and blows it to the ground. The water stains on the ground after being cleaned can be further quickly dried after blowing, and the air outlet 25 blows air close to the ground, which has a higher drying efficiency, so as to avoid the situation where the ground with water stains after cleaning is repeatedly stepped on and becomes dirty again or causes users to slip. Preferably, the fan 3 is a blower with a volute wind casing and a centrifugal fan, which can bring stronger wind pressure and stronger wind force. The fan 3 is set separately for blowing, and the power or gear can be adjusted to change the wind force of the fan 3, so as to debug the best air outlet effect to achieve the purpose of quickly drying the ground.

[0027] As a preferred embodiment of the present invention, the air outlet 25 is a strip-shaped air outlet and is arranged across the bottom of the floor brush shell 21 from left to right and parallel to the mopping roller brush 22. Fan-shaped air discharge is achieved through the strip-shaped air outlet 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 groove 26 on the bottom surface of the floor brush shell 21. The end of the strip groove 26 is provided with an air inlet connected to the fan 3, so that the fan 3 is connected to the end of the air outlet 25. The wind blown by the fan 3 first enters the strip groove 26 and fills the entire strip groove 26 under the guidance of the wall of the strip groove 26, and then the air is discharged as a whole from the air outlet 25. Furthermore, the top wall of the strip groove 26 is inclined and toward the rear of the floor brush 2, so that the air outlet 25 can be directed toward the rear of the floor brush 2 to avoid directly blowing the floor-wiping roller brush 22 to affect the floor-wiping effect, and can continuously blow air to the ground behind, resulting in a better drying effect.

[0028] The above-mentioned fan 3 can be arranged in the main unit 1 or in the floor brush 2. When the fan 3 is arranged in the main unit 1, a connecting pipe is arranged in the main unit 1 and the floor brush 2, so that the fan 3 is connected to the blowing port 25 through the connecting pipe. However, laying the connecting pipe will make the internal structure of the floor scrubber more complicated. Therefore, as a preferred solution, the fan 3 is directly arranged in the floor brush housing 21, and a fan mounting seat 27 is provided in the floor brush housing 21, and the fan mounting seat 27 is connected to the blowing port 25. More directly, the fan mounting seat 27 is arranged above the blowing port 25, and the fan 3 blows air directly above the blowing port 25, reducing the setting of the ventilation channel, and can maximize the wind pressure of the fan 3, so that the wind strength is guaranteed. Preferably, the floor brush housing 21 is also provided with a driving motor 5 for driving the mopping roller brush 22 and a water pump 6 for water supply. Since the driving motor 5 is heavy and the space in the floor brush housing 21 is limited, placing the driving motor 5 on the side of the floor brush housing 21 will affect the balance of the floor brush 2, resulting in uneven cleaning effect. For this reason, the floor brush 2 is able to be counterweighted and balanced through a reasonable structural distribution, wherein the suction channel 23 is arranged in the middle of the inner cavity of the floor brush housing 21, the driving motor 5 is arranged on the right side of the inner cavity of the floor brush housing 21, and the water pump 6 and the fan 3 are arranged on the left side of the inner cavity of the floor brush housing 21. Through the above component distribution, the weight of the left and right sides of the floor brush 2 can be balanced, and the mopping roller brush 22 can be evenly pressed on the ground, which has a better wiping and cleaning effect.

[0029] 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.

[0030] As a preferred solution, a heating element is also arranged at the air outlet of the fan 3, so that the fan 3 can blow out hot air. The hot air can complete the drying work more quickly, and the hot air also has a certain disinfection effect.
