[0053] The body structure 2 can be detachably connected to the handle structure 1 and the floor brush structure 3, and the battery pack assembly 104 is located in the handle structure 1, and the clean water tank 202 and the sewage tank 306 are respectively located in the body structure 2 and the floor brush structure 3; through the above structural layout, the occupied space of the floor washer in transportation packaging can be reduced, which is convenient for product transportation and improves the efficiency of packaging and transportation.

[0054] Electrical control principle: The control panel assembly provided on the whole machine mainly consists of a switch button, a mode button, a self-cleaning button and a display panel. The switch button controls the power on and off of the whole machine; the mode button realizes the switching of various working modes (dry suction mode, wet mopping mode, etc.); the self-cleaning button controls the whole machine to enter / exit the self-cleaning mode, and the display panel mainly displays: power, abnormal alarm prompts (such as brush blockage, full sewage tank 306, working mode, etc.). The battery pack assembly 104 is assembled by power supply battery cells and PCBA, and serves as the power supply and control unit of the whole machine.

[0055] The working modes of the floor washer are basically divided into three types: dry suction mode, wet mopping mode, and self-cleaning mode.

[0056] (1) Working mechanism of the dry suction mode: The user presses the switch button, and the battery pack supplies power. Press the mode button to switch to the dry suction mode. The vacuum motor assembly 307 and the brush driving motor work, and the water pump does not work. The whole machine starts to work normally. Press the switch button again, and the above functional components are powered off and stop working.

[0057] (2) Working mechanism of the wet mopping mode: The user presses the switch button, and the battery pack supplies power. Press the mode button to switch to the wet mopping mode. The vacuum motor assembly 307 and the brush driving motor work, and the water pump works. The whole machine starts to work normally. Press the switch button again, and the above functional components are powered off and stop working.

[0058] (3) Self-cleaning mode working mechanism: The user presses the switch button, and the battery pack supplies power. Press the mode button to switch to the self-cleaning mode, then press the self-cleaning button. The vacuum motor assembly 307 and the roller brush drive motor work, and the water pump works. The whole machine starts self-cleaning. Press the self-cleaning button to end the self-cleaning. Press the switch button to cut off the power supply of the above functional components and stop working.

[0059] Among them, in the self-cleaning mode, the battery pack assembly 104 controls the rotation direction of the roller brush, the water pump flow rate and the operation time of each component according to a certain logic to achieve the cleaning purpose, which is different from the logic settings of other working modes.

[0060] Water spraying principle: The inlet end of the water pump is connected to the clean water tank 202 through a pipeline and a structural member. The outlet end of the water pump is connected to the nozzle 41 through a pipeline. The nozzle 41 is provided with a water passage and a water outlet. Press the switch button and the mode switching button, and the whole machine enters the wet mopping or self-cleaning mode. The water pump works. A negative pressure is generated at the inlet end of the water pump to extract the water in the clean water tank 202 through the pipeline and the pump body, and the water is pumped out from the outlet of the pump (a positive pressure is generated at the outlet end of the water pump) and sprayed onto the roller brush assembly 304 through the outlet pipeline from the outlet of the nozzle 41 to achieve the purpose of wetting or cleaning the roller brush.

[0061] As Figure 5 shown, the dust removal / dirt removal working principle: The user presses the switch button, and the whole machine is powered on and works. The drive assembly 303 drives the roller brush assembly 304 to rotate counterclockwise towards the ground brush inlet air duct 7, dragging (sweeping) the solid / liquid garbage on the cleaning surface towards the ground brush inlet air duct 7. At the same time, the vacuum motor assembly 307 rotates at a high speed to generate a negative pressure and a certain flow rate of air flow in the air duct (the so-called air duct includes: the motor air duct, the box body outlet 9, the sewage tank 306, the box body inlet 8 and the ground brush inlet air duct 7, and all pipeline connections need to ensure good sealing). The air flow direction is from the side of the ground brush inlet air duct 7 to the vacuum motor assembly 307. The solid / liquid garbage dragged and swept towards the ground brush inlet air duct 7 by the roller brush enters the sewage tank 306 from the box body inlet 8. After the solid-liquid separation and gas-water separation processes are completed in the sewage tank 306, the air filtered by the sewage tank 306 is discharged from the box body outlet 9, passes through the motor air duct, the vacuum motor body, and the motor chamber, and finally is discharged into the atmosphere from the air outlet grilles on both sides of the machine body. The cleaning cycle is real-time and continuous during the whole working process of the machine.

[0062] Embodiment 2

[0063] As Figure 4 - Figure 9 shown, on the basis of Embodiment 1, the present invention also proposes a water scraping assembly 4 provided behind the roller brush assembly 304.

[0064] The wiper assembly 4 includes a nozzle 41 communicated with the clean water tank 202, and the nozzle 41 is installed on the front side of the floor brush main body 301; a wiper blade 42 or / and a comb plate 43 is installed on the nozzle 41, and the front end of the wiper blade 42 or / and the comb plate 43 is embedded in the flannelette layer 3042.

[0065] The wiper blade 42 and the comb plate 43 can cooperate with each other up and down and exist simultaneously, or can be set separately; when they exist simultaneously, the comb plate 43 and the wiper blade 42 overlap each other, the comb plate 43 is located below the wiper blade 42, and both are installed at the bottom of the nozzle 41.

[0066] Specifically, assembly holes 433 are formed in both the comb plate 43 and the wiper blade 42, and the two can be fixed on the nozzle 41 by screwing through the assembly holes 433.

[0067] As described above, the comb plate 43 includes a plate body 431 connected to the nozzle 41. The plate body 431 has a bent structure, and a plurality of comb teeth 432 are arranged at equal intervals at its end. A notch is provided on one side of the root of the comb teeth 432 to form an inverted buckle, and preferably, the plurality of comb teeth 432 are symmetrically distributed with respect to the center line of the plate body 431.

[0068] Such as Figure 8 - Figure 10 shown, the design values of several key dimensions of the comb teeth 432 are respectively:

[0069] Angle α: 0° ≤ α ≤ 90°, b value: 0.5 mm ≤ b ≤ 20 mm, c value: 0.1 mm ≤ b ≤ 10 mm, angle β: 0° ≤ β ≤ 100°.

[0070] The angle range of the cooperation between the wiper blade 42 and the rotating central axis of the roller brush assembly 304 is: 0° - 360°. The interference amount X value between it and the flannelette layer 3042 is: 0 mm ≤ X ≤ 10 mm; the bending angle B value of the plate body 431 is: 0° ≤ B ≤ 180°, and it is tangent to the circumferential direction of the roller brush assembly 304; the interference amount Y value between it and the flannelette layer 3042 is: 0 mm ≤ Y ≤ 10 mm; the wiper blade 42 and the comb plate 43 can be made of hard materials (such as metal, plastic, etc.) or soft materials (such as LDPE, rubber, silicone, etc.). The processing process of the comb plate 43 is completed by chemical etching, wire cutting processing, laser cutting and other processes.

[0071] Principle of hair anti - entanglement of the roller brush assembly 304: The roller brush assembly 304 is composed of a roller brush body 3041 and fluff / flannel (i.e., flannel layer 3042) attached to the roller brush body 3041. During the cleaning process, the fluff / flannel will absorb a certain amount of moisture when contacting liquid waste, and the nozzle 41 will spray water on the fluff / flannel during the wet mopping process, resulting in water stains remaining when the fluff / flannel contacts the cleaning surface; and during the whole - machine cleaning process, when encountering hair, long - fiber - like waste, it will be wound around the roller brush assembly 304, causing the hair, long fibers and flocculent dirt not to be cleaned thoroughly and remaining on the roller brush assembly 304, and even causing the hair, long fibers and flocculent dirt to be wound around the driving motor end, resulting in abnormal product functions and damage. To better solve the problem of water stain residue on the ground and the winding problem, a wiper blade 42 or a comb - tooth plate 43 is arranged at the upper end of the floor brush inlet air duct 7 at the rear side of the roller brush assembly 304.

[0072] There are two implementation methods in the prior art:

[0073] Technical solution layout of the prior art one: The wiper blade 42 is arranged in a direction perpendicular to the axis of the roller brush body 3041, and there is a certain interference amount between the wiper blade 42 and the roller brush body 3041. This layout has a certain improvement effect on the water stain residue on the ground, but the cleaning effect on hair, long fibers and flocculent dirt is not ideal. Hair or fibers, flocculent dirt will be wound around the roller brush body 3041, causing difficulties for users to clean or abnormal operation of the whole machine.

[0074] The structural layout of the prior art two is basically the same as that of the prior art one. The difference is that: the wiper blade 42 is provided with a comb - tooth structure and the wiper blade 42 is bent at a certain angle to form a certain included angle with the circumference of the roller brush body 3041, and there is a certain interference amount between the wiper blade 42 and the roller brush body 3041. This layout has a significant improvement in the cleaning effect on hair or fibers, flocculent dirt, but cannot completely avoid the winding of hair or fibers, flocculent dirt around the roller brush body 3041. Due to the comb - tooth structure of the wiper blade 42, it cannot be completely attached to the roller brush body 3041, resulting in poor drying effect of the roller brush body 3041, water stain residue on the ground or the need to repeat the cleaning action multiple times to collect it cleanly, and the user experience is not very ideal.

[0075] To better solve the problems of water stain residue on the ground and hair winding, the layout of the utility model patent is: at the rear side of the roller brush assembly 304, a wiper assembly 4 is arranged at the upper end of the floor brush inlet air duct 7. The wiper assembly 4 is composed of a nozzle 41, a wiper blade 42 and a comb - tooth plate 43. The three are fixed to form a component through processes such as screws, buckles or bonding. The wiper blade 42 and the comb - tooth plate 43 are respectively designed with interference with the roller brush assembly 304. The special feature of the utility model patent is:

[0076] (1) The wiper blade 42 and the comb - tooth plate 43 exist in an up - and - down cooperation.

[0077] (2)Differences in the shape and arrangement of the comb teeth 432 on the comb plate 43.

[0078] The comb tooth structure layout on the comb plate 43 can effectively prevent hair from easily escaping to both sides under the action of the rotational force of the roller brush, and the comb tooth structure layout can also effectively cut the hair, ultimately achieving the effect of preventing the roller brush from being entangled.
