Fig. 1 is a schematic diagram for explaining the principle of the cleaning assembly, and takes a cleaning roller 1 with cleaning fins 2 as an example (in the figure, a large cleaning roller 1a is positioned in front of a small cleaning roller 1b), two cleaning rollers 1 are connected side by side and installed at the front side of a machine shell 4, the plane needing cleaning such as the ground is a working surface, the dirt inlet end of the cleaning assembly, namely the side where the two cleaning rollers 1 enter the garbage, is generally the side contacting with the ground, the dirt outlet area is the side where the garbage is discharged, namely the side where the two cleaning rollers 1 are separated from the contact with each other, and a triangular-like area formed between the two cleaning rollers 1 and the working surface is a dirt inlet area 43. The floor sweeping machine mainly achieves a floor sweeping function, meanwhile has a certain floor mopping and water collecting capacity, improves the sweeping experience, and the property is particularly emphasized here. The two cleaning rollers 1 rotate in opposite directions, and at the position where the cleaning rollers contact each other at the middle, the movement direction is upward, and a butt clamp moving upward is formed. When sweeping the rubbish, after touching the rubbish on the ground, the cleaning fins 2 can be bent or compressed, scrape the ground for cleaning, and finally carry the rubbish, the rubbish is mainly fed from the cleaning roller 1 on the front side when moving to the front side, the front side is a main rubbish inlet, because the bottom end of the machine shell 4 is at a certain height above the ground, the small rubbish smaller than the height can pass through the bottom end of the machine shell 4, and the small rubbish can enter the cleaning assembly from the cleaning roller 1 on the rear side when moving to the rear side; simultaneously, the mop has the function of mopping and collecting water, when water exists on the ground, in the circumferential rotating process, on the pointed side of the mopping advancing direction, the cleaning fins 2 firstly form an acute angle with the ground when beginning to touch the ground, so that the mopping effect is better, at the moment, the problems of jumping, blocking and the like are not easy to occur, therefore, the cleaning roller 1 rotating anticlockwise moves backwards, the mopping effect is better, and the cleaning roller 1 rotating clockwise moves forwards, the mopping effect is better. And between the single cleaning fin 2 from the ground contact to the rotation away from the ground, effective scraping distances (different hardness, different shapes and different lengths of the cleaning fins 2 or other types of cleaning rollers 1 are formed, the formed effective scraping distances are different and can be measured through experiments and the like to determine the density or angle intervals of the cleaning fins 2, and the like) exist, the effective scraping distances are intervals with good ground scraping effects (the ground is scraped cleanly), the ground scraping effects are good, continuous and effective ground scraping is required to be guaranteed, namely continuity (overlapping) exists among the effective scraping distances of the cleaning fins 2 of the cleaning roller 1, the clean continuity of the ground scraping is guaranteed, and the situation that strip-shaped water marks are left without being scraped cleanly or scraped is avoided.

The first embodiment, fig. 2, includes a cleaning assembly, and the cleaning assembly is installed in the front of the housing 4, the garbage bin 3 is located at the rear, the cleaning assembly includes two cleaning rollers 1, and the diameter of the front cleaning roller 1 is larger than that of the rear cleaning roller 1, and the two cleaning rollers 1 are used for picking up garbage and dirty water.

As shown in fig. 3, the power and transmission unit includes a transmission device, a driving motor 9, and a battery, the transmission device includes a main chain wheel 11 connected to an output end of the driving motor 9, a first chain wheel 13 connected to an end of the large cleaning roller 1a in a matching manner, and a second chain wheel 14 connected to an end of the small cleaning roller 1b in a matching manner, the main chain wheel 11 is driven by the first chain wheel 13 and the second chain wheel 14 through a chain 12, and the large cleaning roller 1a and the small cleaning roller 1b rotate in opposite directions. The left side of the machine shell 4 can be provided with a transmission cavity 15 and is matched with a mounting cavity cover 16, the transmission device is arranged in the transmission cavity 15, and the transmission cavity 15 is matched with the mounting cavity cover 16 (the transmission device can be an independent component and is matched and mounted on the machine shell 4). The transmission device can be double-sided belt wheel transmission, pure gear transmission, belt wheel and belt transmission matched gear transmission, chain 12 and chain wheel matched gear transmission, worm and gear transmission and the like besides the chain 12 and chain wheel transmission. In this embodiment, the driving motor 9 may be installed in the power compartment 8, and the power compartment 8 may be located at the upper end of the rear portion of the garbage bin 3 (the position of the power compartment 8 is not limited to the upper end of the rear portion of the garbage bin 3, and may be set at a suitable position in the garbage bin 3 or the housing 4, such as the position of the upper end of the front portion of the garbage bin 3 near the cleaning assembly, or the lower end of the front portion of the garbage bin 3). In the attached figure 4, the driving motor 9 can also be arranged at the left side or the right side of the machine shell 4, the output end of the driving motor 9 is directly connected with a single cleaning roller 1 for transmission, and the other cleaning roller 1 in the same group is driven to rotate reversely by conventional power transmission equipment; driving motor 9 still can install in the inside left side of casing 4, driving motor 9 cup joints the cooperation and sets up the axle center position at cleaning roller 1, be located cleaning roller 1 inside, driving motor 9's output is connected with cleaning roller 1, save the occupation of left and right sides direction space, when needs outside output power, for example, drive another cleaning roller 1 and rotate, can set up biax driving motor 9, the one end of driving motor 9 output is connected with the cleaning roller 1 that cup joints the setting, the other end can be connected with transmission and drive another cleaning roller 1 and rotate, other embodiments also are suitable for this kind of driving motor 9 mounting means. The power and transmission unit can also be realized without electric energy, for example, when a user pushes the machine shell 4 to move, the rotation of the wheels 20 forms power, then the transmission device drives the cleaning assembly to rotate, and the two cleaning rollers 1 rotate reversely.

Two cleaning roller 1 all install at casing 4 anteriorly, and install in tandem, in the intermediate position of the two, the mutual extrusion of cleaning fin 2 of the two, form crisscross extrusion region, the two downside all contacts ground and extrudees with ground, big cleaning roller 1a anticlockwise rotation, little cleaning roller 1b clockwise rotation, provide power by power and drive unit and drive the rotation, rely on chain 12 to carry out the transmission simultaneously, first sprocket 13 is in the inboard of chain 12, second sprocket 14 is in the outside, respectively with the transmission of chain 12 meshing, then two cleaning roller 1 turn to oppositely. In the process of pushing forwards and pulling backwards, the sweeping and mopping functions can be realized simultaneously, the sweeping function is realized by clamping two cleaning rollers 1, the mopping and water collecting functions are realized by mainly depending on the cleaning roller 1 rotating clockwise at the rear side when the mopping device moves forwards, and the mopping device moves backwards by mainly depending on the cleaning roller 1 rotating anticlockwise at the front side, so that the floor attached garbage is removed from the floor by wetting the floor with water (the special emphasis is made here, the general attached garbage such as soil can be removed, the cleaning effect on the adhesive garbage is poor, and the cleaning effect of the mopping and sweeping function is not considered). For the picking function of the garbage and the water, the cleaning fins 2 of the cleaning rollers 1 can carry some garbage and dirty water on the surfaces by carrying and clamping the two cleaning rollers 1 in the rotating process, a triangular area (the size of the triangular area, such as the diameter and the center distance of the two cleaning rollers and the pressing contact degree of the dirt inlet ends of the two cleaning rollers and a working surface) exists at the lower part of the middle part (namely the staggered extrusion area) of the two cleaning rollers 1 (the cleaning assembly can be adjusted by adjusting and setting parameters of the cleaning rollers 1, the cleaning fins 2 can not touch the places circumferentially, for some smaller garbage, the smaller garbage can not be simultaneously extruded and clamped by the two cleaning rollers 1, the garbage and the water can be picked up mainly by two conditions, firstly, the rotating cleaning fins 2 have certain carrying force, the garbage and the water can be attached to the cleaning fins 2, secondly, the garbage and the water can be knocked off or warped under the stirring of the continuously rotating cleaning fins 2, make it can be got by the lifting clamp, especially clean fin 2 scrapes the back from subaerial, breaks away from the twinkling of an eye on ground, clean fin 2 end produces certain ejection acceleration effect, and the end of clean fin 2 is the one end of keeping away from the axle center, and in the same way, rubbish and water constantly hit between two cleaning rollers 1 and fly the transmission, and each other does not contact between two cleaning rollers 1, also can realize cleaning the function of picking up rubbish and water. Two cleaning roller 1 parameters can be set through adjustment in the cleaning assembly, the size of the dirt inlet area 43 is adjusted, for example, the diameter and the center distance of the two cleaning roller 1 parameters, the parameters such as the pressing contact degree of the dirt inlet end and the working surface of the two cleaning roller 1 parameters and the height of the rotating shaft distance, the size of the dirt inlet area 43 is adapted to the corresponding working environment, for example, when the volume of the mainly picked-up garbage or the waste is large (for example, the garbage is similar to table tennis type garbage picking), the size of the dirt inlet area 43 is adapted to the dirt inlet area 43, the clamping is better realized, the dirt inlet area 43 is prevented from being too small, the object to be picked up cannot enter, or the dirt inlet area 43 is too large, and the object to be picked up is not easy to be clamped or hit to fly to pick up. During fitting, the shapes are not required to be the same, and when the cleaning rollers 1 are rubber rollers, the cleaning fins 2 have the deformation capacity, the articles can be actually clamped slightly larger than the size of the dirt intake area 43 displayed in a static state, meanwhile, the center distance of the two cleaning rollers 1 is considered, and the selection of specific parameters and the fitting of the size of the dirt intake area 43 can be determined according to experiments.

After the cleaning rollers 1 carry garbage or water, separation is realized in the casing 4, self-cleaning of the cleaning rollers 1 is realized, the cleaning rollers can depend on the rotating centrifugal force and the elastic throwing action of the two cleaning fins 2 on an object finally when the two cleaning rollers 2 are extruded and rotated, the two cleaning rollers 1 are extruded in the middle, after the extrusion stage, the cleaning fins 2 can be elastically released and thrust resultant forces of the cleaning fins 2 on the front side and the rear side on the object are generated, the throwing of the object can be favorably realized, the two cleaning rollers 1 have different diameters and different center distances, the staggered extrusion areas are different, the final throwing angles are different, when the diameter of the cleaning roller 1 on the rear side is smaller than that of the cleaning roller 1 on the front side, the throwing angle points to the upper rear side, and the cleaning roller 1 on the rear side is also caused to bear and transport more garbage and water in the upper area (the position is one of the reasons for removing the structure of the upper scraper 25, the structure can be simplified and the resistance can be reduced). The garbage bin 3 can contain garbage and water, the front end of the garbage bin 3 can be close to or pressed into the rear side of the small cleaning roller 1b, and the garbage and water are reduced to continue rotating along with the cleaning roller 1.

Fig. 5, this embodiment can also increase the anti-drip plate 5, and the anti-drip plate 5 sets up in little cleaning roller 1b rear, and anti-drip plate 5 mainly connects the water droplet that little cleaning roller 1b rear side was thrown away and not connect the part of collecting by the garbage bin 3 flourishing greatly, or the water droplet that overflows from the garbage bin 3 front end, and the increase of anti-drip plate 5 can further improve little cleaning roller 1b rear side and not drip the not residual effect of water. As shown in FIG. 6, the anti-dripping plate 5 can be obliquely arranged, and the anti-dripping plate 5 can be installed on the machine shell 4 and also can be installed at the front part of the garbage bin 3. The lower end of the drip-proof plate 5 can be contacted with or not contacted with the end of the cleaning fin 2 of the small cleaning roller 1b, so that water drops can be carried away by the cleaning fin 2. When the anti-dripping plate 5 is contacted with the tail end of the cleaning fin 2, a small amount of water drops contained on the anti-dripping plate 5 can be carried by the tail end of the cleaning fin 2 again and can not drop, or can be swept and ejected into the effective scraping distance by the cleaning fin 2 again or onto the cleaning fin 2 on the front side of the effective scraping distance, and the anti-dripping plate 5 can also be horizontally arranged and contacted with the small cleaning roller 1b, as shown in fig. 6.

Fig. 7 shows that in this embodiment, the cleaning roller 1 separates the garbage and water, and the cleaning roller can further rely on a dirt scraping device, that is, a lower scraper 24 is added to contact or press the cleaning fins 2 of the small cleaning roller 1b in a tangent manner to perform rigid scraping, and meanwhile, the cleaning fins 2 impact on the dirt scraping end of the lower scraper 24, so that the shaking or ejection of the tail ends of the cleaning fins 2 can be triggered, the garbage and water can be separated from the cleaning fins 2, and finally the garbage and water fall into the garbage bin 3 from the falling end of the lower scraper 24, and the front end of the garbage bin 3 can contain water drops thrown out by the small cleaning roller 1b and dirt flowing down from the falling end of the lower scraper 24. Similarly, an upper scraper 25 may be additionally installed in the housing 4, the upper scraper 25 is used for cleaning the large cleaning roller 1a, and both the upper scraper 24 and the lower scraper 25 may be used as dirt scraping means.

The upper scraper 25 and the lower scraper 24 are respectively installed on the upper side and the lower side of the front part in the machine shell 4, the self-cleaning of the cleaning roller 1 is respectively realized for the large cleaning roller 1a and the small cleaning roller 1b, the upper scraper 25 and the lower scraper 24 can be selectively installed according to the actual self-cleaning effect, the relation between the upper scraper 25 or the lower scraper 24 and the cleaning fins 2 is selected to be matched spacing, or tangent position contact or pressing contact, the pressing contact degree is that in the rotating circumference of the cleaning roller 1, the maximum depth pressed in by the upper scraper 25 or the lower scraper 24 is selected (for example, in the use environment of cleaning large garbage, the scraping end of the lower scraper 24 can have a certain spacing with the tail end of the cleaning fins 2 of the small cleaning roller 1b, the impact and the friction between the lower scraper and the cleaning fins are reduced, and simultaneously the large garbage can be prevented from being separated, and the overall shape needs to be considered for the judgment of the size of the garbage).
