In a preferred embodiment, the first and second roll brushes 2 and 3 are positioned at both sides of the air path 22, and the soil tank 5 is positioned above the air path 22, so that the distance between the soil tank 5 and the suck-back port 21 is minimized, the volume of the scrubber main body 1 is reduced,

the first rolling brush 2 and the second rolling brush 3 are contacted with the ground, a scraping strip 23 and a spray head 24 are arranged above or on the side of the first rolling brush 2, the spray head 24 is connected with the purified water tank 4 through a water pipe to spray purified water to the first rolling brush 2,

the length of the scraping strip 23 is the same as that of the first rolling brush 2, the scraping strip 23 is abutted to the first rolling brush 2, and dirt and dirty water in the sweeping process of the first rolling brush 2 through the scraping strip 23 are scraped off, so that the first rolling brush 2 can be continuously swept.

In the utility model, the first rolling brush 2 is kept wet and clean by continuously spraying water and scraping and pressing the first rolling brush 2, so that the ground is continuously swept and mopped, furthermore, after the first rolling brush 2 sweeps and mops, water stains on the ground are remained, and the second rolling brush 3 wipes and dries the water stains.

In a preferred embodiment, a scraping strip 23 is also disposed above or beside the second rolling brush 3 to scrape and squeeze the dirt and water adhered to the second rolling brush 3 to keep the second rolling brush 3 clean and dry.

In a preferred embodiment, the spray head 24 has a bar shape, and has a length similar to that of the first rolling brush 2, and a plurality of spray holes 241 are provided on the spray head 24, as shown in fig. 3, in cooperation with the rotation of the first rolling brush 2, so that the water can wet the entire surface of the first rolling brush 2.

Preferably, the spray holes 241 are uniformly arranged on the spray head 24 in one or more rows, as shown in fig. 4, so that the wetting degree of different positions on the surface of the first rolling brush 2 is uniform, and mopping can be better performed to avoid the problem of uneven mopping effect.

In a preferred embodiment, the diameter of the nozzle 241 is 0.3 to 5mm, which not only ensures the uniformity of the sprayed water flow, but also prevents the nozzle from being blocked by water scale, micro impurities in water, and the like.

In a more preferred embodiment, in order to ensure that the water is uniformly sprayed, a water chopping head 242 is provided at the center of the spraying hole 241 to break up the sprayed water, so that the water sprayed from the spray head 24 can uniformly wet the first roller brush 2 as the first roller brush 2 rolls, as shown in fig. 5.

In a more preferred embodiment, the nozzle hole has a limiting wall 243, and the water splitting head 242 and the limiting wall 243 cooperate to divide one nozzle hole into at least two water outlets, as shown in fig. 4 and 5, the water outlets of the plurality of nozzle holes 241 are aligned in a row and parallel to the axis of the first rolling brush 2, so that the water split by the water splitting head 242 is axially sprayed out along the first rolling brush 2.

Further, a water pump is provided in the clean water tank 4 to adjust the water spraying speed of the spray head 24, so that the floor washing machine can adapt to different working environments.

Specifically, the water pumping speed is fast when the ground is dirty and needs to be strongly cleaned, and the water pumping speed is slow when the first roll brush 2 and the ground are clean.

The inventors have found that when the pumping speed is high, since the water pressure is high, the scattering range of the water sprayed after the spray holes 241 are scattered by the water chopping head 242 is increased, and a phenomenon in which the water is sprayed to the region outside the first roll brush 2 may occur.

Preferably, the outer side of the nozzle 241 has an inclined flow guide wall 244, and the flow guide wall 244 blocks the water flow with an excessive scattering range, so that the water flow is splashed back onto the first rolling brush 2.

In a preferred embodiment, the scraping strip 23 is pressed into the surface of the first rolling brush 2 and/or the second rolling brush 3, so that the scraping strip 23 can be in sufficient contact with the rolling brush to scrape the surface of the rolling brush and hang dirt and dirty water, and preferably, the scraping strip is pressed into the surface of the rolling brush by 0.1-8 mm.

More preferably, the scraping strip 23 is pressed into the position 1-2.5 mm below the surface of the rolling brush, and the inventor finds that when the pressing depth of the scraping strip 23 into the rolling brush is large, large resistance is generated on the rolling brush, so that the output power of the motor assembly is obviously increased, the power consumption of a battery is accelerated, the abrasion degree of the rolling brush is increased, when the pressing depth of the scraping strip 23 into the rolling brush is small, the scraping amount of adsorbed sewage in the rolling brush is small, and the cleaning effect of the rolling brush is poor.

According to the present invention, the outer surface of the first rolling brush 2 and/or the second rolling brush 3 may be made of a material having a cotton material, a polyester material, or a mixture of cotton and polyester.

The inventor finds that cotton and polyester materials have the characteristics of being easy to adhere to dirt and dust, water absorption not changing along with the service time, being capable of being repeatedly scraped and the like, and compared with materials such as sponge and the like, the water-saving brush has the advantages of being moderate in water storage amount, wear-resistant, not easy to damage and the like, so that the service life of the brush is obviously prolonged.

In a preferred embodiment, the dirt and dirty water scraped by the first rolling brush and/or the second rolling brush is collected by the baffle plate so as to avoid secondary pollution to the ground.

In a preferred embodiment, the filtration is performed in the waste water tank to prevent dirt and dirty water from entering the fan and causing damage to the fan.

In a preferred embodiment, the dirt value of the sucked dirt water is detected, and when the detected dirt value is lower than a threshold value, the water spraying amount of the spray head is kept to be an initial value; when the detected dirt value is higher than the threshold value, the water spraying amount of the spray head is increased, the cleaning effect on the first rolling brush is improved, and therefore the sweeping and mopping effect on the ground is enhanced.

More preferably, when the amount of water sprayed by the spray head is increased, the rotating speed of the fan is increased, so that the suction force of the air duct is increased, dirty water is prevented from falling onto the ground, and when the amount of water sprayed is decreased, the rotating speed of the fan is decreased, so that electric energy is saved, and the running noise of the floor washing machine is reduced.

In a preferred embodiment, when the detected dirt value is higher than the threshold value, the spray heads above or at the side of the second rolling brush are opened, clean water is sprayed to the second rolling brush, and the first rolling brush and the second rolling brush perform sweeping simultaneously, so that the heavy dirt can be swept clean at one time.

In a preferred embodiment, when the ground is heavily polluted, the first rolling brush is replaced by a scrubbing brush ground rolling brush, and meanwhile, a spray head above or on the side of the second rolling brush is opened, so that the functions of strongly sweeping and sucking the ground by the first rolling brush and spraying water to mop the ground by the second rolling brush are realized.

In a preferred embodiment, when the floor surface is a carpet, the carpet can be cleaned by replacing the first and second rolling brushes with bristle brush rolling brushes.

The present invention has been described above in connection with preferred embodiments, but these embodiments are merely exemplary and merely illustrative. On the basis of the above, the utility model can be subjected to various substitutions and modifications, and the substitutions and the modifications are all within the protection scope of the utility model.
