Example 1

The present embodiment provides a floor scrubber, please refer to fig. 1 and 2. The floor scrubber includes a housing 10, a roller brush 20, a water spray assembly 30, a water pump (not shown), and a motor (not shown).

The housing 10 is formed with an open cavity in which the roller brush 20 is disposed. The motor is connected with the round brush 20 transmission for drive round brush 20 rotates, and the water pump sets up in casing 10, including water inlet end and play water end, water inlet end and water source intercommunication, when the water pump during operation, can suck the water source in order to spray to round brush 20.

The water spray assembly 30 is disposed in the housing 10 immediately adjacent to the roller brush 20 and includes a water spray surface 32 and water jets 320 disposed on the water spray surface. The water jet assembly 30 further includes a water inlet 35 in communication with the water jet 320, the water inlet 35 being in communication with the water outlet of the pump via a conduit. In other words, the water outlet end of the water pump, the water inlet 35 of the water spraying assembly 30, and the water spraying port 320 are sequentially connected, and when the water pump operates to suck the water source, the water pressurized by the water pump enters the water spraying assembly 30 through the water inlet 35 and then is sprayed to the roller brush 20 through the water spraying port 320.

The floor washing machine also comprises a controller which is connected with the water pump and the motor and used for controlling the operation of the water pump and the motor. The floor washing machine is also provided with an operation key which is used for man-machine interaction to receive an operation instruction, the operation key is in communication connection with the controller, an operation signal of the operation key can be sent to the controller, and the controller controls the working state of the floor washing machine.

The floor scrubber also comprises a sewage tank, a sewage return pipeline for the cleaned sewage to flow to the sewage tank and a liquid supply pipeline for conveying clean water to the rolling brush. One end of the sewage return pipeline is communicated with a cavity for accommodating the rolling brush 20, and the other end of the sewage return pipeline is communicated with a sewage tank. The floor scrubber further comprises a connection pipe 50 connected above the working head, which connection pipe 50 is used for the return dirt channel and the feed liquid channel to pass through. An operating part is also provided above the connection pipe 50 for a user to operate to control the floor scrubber. In general, the operation keys are provided on the operation unit.

The floor scrubber further includes a wringer 60, the wringer 60 being in abutting contact with the surface of the roller brush 20. During the rotation of the roller brush 20, the surface of the roller brush 20 is sequentially extruded by the water squeezing member 60 to flow out of the surface of the roller brush, and the attached dirt flows out along with the extruded water flow and is finally collected by the sewage tank. Specifically, the wringing component 60 further includes comb teeth, and the tips of the comb teeth can be inserted into the nap of the roller brush 20 to a certain extent, so as to peel off the dirt in the nap of the roller brush, thereby being convenient for recycling along with sewage.

In a specific embodiment, the water squeezing member 60 is disposed below the water spraying assembly 30, the water squeezing member 60 is fixedly connected to the water spraying assembly 30, and after the water squeezing member 60 squeezes water, the water spraying assembly 30 sprays water to wet the surface of the rolling brush 20 immediately after squeezing water, so as to wet the surface of the rolling brush 20.

For convenience of explanation, the upper part of the drawing sheet shown in fig. 1 is defined as upper, one side where the rolling brush is provided is the front, and the opposite direction is the rear. In the state shown in fig. 1, the working head of the floor washing machine is supported on the cleaning surface, and the control operation part controls the working head of the floor washing machine to move on the cleaning surface so as to realize the mopping of the cleaning surface. The lower part of the rolling brush 20 is exposed and contacts with the cleaning surface, so that the rolling brush rolls on the cleaning surface and can scrape the cleaning surface. When the floor scrubber performs a cleaning operation for a certain time, the roller brush 20 adheres a lot of dust and garbage, and the cleaning ability is lowered, even causing secondary pollution to the cleaning surface.

In this embodiment, the floor scrubber further includes a self-cleaning mode. In the self-cleaning mode, the floor cleaning machine can clean self stains, is convenient for recovering the cleaning degree and keeps the cleaning effect of the next work. In a specific implementation scenario, after the floor cleaning machine performs cleaning work for a certain time, the floor cleaning machine can be placed on the base, and a self-cleaning mode of the floor cleaning machine is started.

In the self-cleaning mode, the controller controls the rolling brush 20 to alternately rotate forward and backward, and simultaneously controls the water pump to spray water to the rolling brush 20. In the course of the alternate forward and reverse rotation of the roll brush 20, the fluff of the roll brush is alternately set up and fallen down due to the squeezing in the different directions of the wringing member. In the case where the nap is erected, the nap can be brought into contact with the inner wall of the cavity and the water spraying surface to clean the inner wall of the cavity and the water spraying surface.

Specifically, the forward rotation angle and the reverse rotation angle of the rolling brush are not more than 360 degrees. That is, the roller brush alternately rotates forward and reverse within a single revolution, and rotates forward for no more than one revolution and then rotates backward for no more than one revolution. Thus, the fluff of the roll brush is alternately set up and laid down during the alternating forward and reverse rotations. When the floor cleaning machine is in a standing state, the fluff can contact the inner wall of the cavity containing the rolling brush and the water spraying surface of the water spraying component, so that the inner wall of the cavity and the water spraying component are cleaned, the floor cleaning machine is more comprehensive in self-cleaning, and the cleaning effect of the floor cleaning machine is further guaranteed.

Because the rolling brush alternately rotates forward and rotates backward, the water pump of the floor washing machine sprays water to the rolling brush at the same time, and in the state that the fluff of the rolling brush is erected, the sprayed water flow is easier to wash away dust adhered on the rolling brush and scrapes away sewage under the action of the scraping strip. Because the rolling brush alternately rotates forward and backward within the range of 360 degrees, the frequency of fluff lodging and rising is faster, and the rolling brush cleaning efficiency is higher.
