Description

[0001] This application is a divisional application of Chinese patent application number 202111512775.3 and invention name “A water and dust circulation cleaning head and cleaning tool”, the contents of which are incorporated herein by reference. Technical Field

[0002] The invention relates to the technical field of cleaning equipment, and in particular to a water-dust circulation cleaning head and a cleaning tool. Background Art

[0003] With the development of modern technology, there are many kinds of floor cleaning tools, including brooms, mops, floor wipes and vacuum cleaners. Vacuum cleaners are very common floor cleaning tools, but they make a lot of noise, which makes people very uncomfortable. And the way they clean garbage is just to suck the garbage into the garbage box.

[0004] Brooms, mops, and floor wipes are sweeping cleaning tools, which generally have a fixed cleaning part. Their cleaning ability is determined by the dirt removal and dirt absorption ability of the cleaning part. Since the cleaning part is contaminated once it comes into contact with the dirty ground, the cleaning ability is gradually weakened in the subsequent cleaning process, especially when cleaning a large area continuously, it is impossible to clean thoroughly. Therefore, these cleaning products must be rinsed frequently, which is very troublesome.

[0005] For Chinese consumers, sweeping and mopping are both necessary when cleaning the floor. Sweeping or mopping alone cannot achieve a thorough cleaning of the floor. However, these existing sweeping and mopping machines either require constant washing or have a complex structure and are very expensive, which makes ordinary consumers shy away from them. Moreover, existing floor cleaning tools can only clean dry garbage (brooms or vacuum cleaners, etc.) or can only be used to clean liquid garbage (mops, floor wipes, etc.). The cleaning effect of mixed dry and wet garbage, especially sticky garbage (such as syrup, ketchup, etc.) is either particularly poor or particularly laborious (for example, using a rag, which requires multiple washings), which can be said to be helpless. Summary of the invention

[0057] The solution of the present application will be described in detail below with reference to the accompanying drawings.

[0058] Figure 1-Figure 3 Shown is a schematic structural diagram of an embodiment of a cleaning head.

[0059] The cleaning head includes a shell and a cleaning roller arranged on the shell and partially in contact with the cleaning surface to clean garbage. The cleaning head also includes a cleaning roller arranged parallel to the cleaning roller for cleaning the surface of the cleaning roller. A cleaning tank is provided along the length direction of the cleaning roller, which is sealed by a pressure strip and a water sealing strip. The pressure strip and the water sealing strip are in contact with the surface of the cleaning roller to form a seal. The cleaning tank is provided with a clean water inlet connected to the clean water tank and a sewage outlet connected to the sewage tank. A pressure relief transfer filter tank is provided between the sewage tank and the cleaning tank. The cleaning tank, the transfer filter tank and the sewage tank form a water washing flow path for washing the surface of the cleaning roller. Since the transfer filter tank 160 can utilize its large space and the space is relatively large relative to the water washing flow path, it can also be combined with one or more measures such as a non-completely sealed structure, so that the air that may appear in the water washing flow path can be relieved and released, so as to avoid the phenomenon that the air in the water washing flow path causes uneven and discontinuous water volume in the cleaning tank, thereby improving the cleaning effect.

[0060] Specifically, the cleaning head 100 includes a cleaning roller 110, a cleaning roller 140, a garbage box 152, a transfer filter bin 160, a group of front wheels 181, a group of rear wheels 182 and a shell 190. Among them, the cleaning roller 110 can be a sponge roller, which is arranged in the shell 190 and is used to clean various dry and wet garbage on the bottom surface. The cleaning roller can be a brush roller, which is used to clean the cleaning roller 110 so that the cleaning roller 110 always keeps a clean state. The garbage box 152 is used to collect various garbage entering the cleaning tool. The transfer filter bin 160 is arranged on the shell 190, and the sewage generated by the cleaning roller 110 after self-cleaning is transferred and filtered through the water tank arranged on the shell 190, and it is convenient for the user to clean and maintain. A group of front wheels 181 and a group of rear wheels 182 are used to provide support for the cleaning head 100. The shell 190 is used to accommodate various components.

[0061] like Figure 3 As shown, the shell 190 specifically includes an upper shell 191, a cover plate 192, a rear shell 193 and a lower shell 194. The upper shell 191 constitutes the upper surface of the cleaning head 100 and can be opened in the direction from the front wheel 181 to the rear wheel 182. The rear shell 193 constitutes the rear surface of the cleaning head 100. The lower shell 194 constitutes the lower surface of the cleaning head 100. The cover plate 192 is arranged above the cleaning roller 110 and can be integrally formed with the upper shell 191. The openable upper shell 191 can seal and wrap the cleaning roller 110 and the cleaning roller 140 to ensure the humidity of the rollers. The cleaning roller 110 is detachably fixed to the shell 190. During operation, the cleaning roller 110 rotates under the drive of the driving device. The cleaning roller 140 is disposed behind the cleaning roller 110 in the rotation direction, and rotates counterclockwise with the cleaning roller 110 to clean the cleaning roller 110 and sweep the garbage on the cleaning roller 110 into the first garbage box 150 for centralized treatment.

[0062] The cleaning head 100 according to the exemplary embodiment of the present application can perform self-cleaning, supply clean water to the cleaning drum 110 through the clean water channel, and collect the sewage generated after the cleaning drum 110 is cleaned into the sewage tank through the water tank (not shown in the figure) provided on the housing 190. Figure 3 As shown, the cleaning head 100 also includes a water pressure plate 120 and a water sealing strip 130. The water pressure plate 120 is disposed above the cleaning roller 110 and contacts the surface of the cleaning roller 110 to squeeze the cleaning roller 110. The water sealing strip 130 is disposed above the cleaning roller 110 and contacts the surface of the cleaning roller. The water pressure plate 120 is detachably connected to the water sealing strip 130, and forms a water storage space connected to the water tank with the surface of the cleaning roller 110, so that the sewage squeezed out of the cleaning roller 110 is gathered and drained to the water storage space, and then gathered to the transfer filter bin 160 through the water tank.

[0063] like Figure 3 As shown, the cleaning head 100 further includes a shovel bar 170, which is disposed on the housing 190 and is located at the side and rear of the cleaning roller 110, and cooperates with the cleaning roller 110 to form a garbage collection channel, collects the cleaned garbage into the cleaning roller 140, and further collects it into the first garbage box 150. According to the exemplary embodiment of the present application, the shovel bar 170 can be a silicone shovel bar. The first shell 191 that can be flipped over, on the one hand, forms a closed garbage channel with the cleaning roller 140; on the other hand, it is convenient to take out the cleaning roller for cleaning.

[0064] The trash box 152 can be a paper box or other blister box, and is arranged below the cleaning drum 140. The shape of the trash box 152 is similar to a U-shaped track, and can be taken out from the side of the cleaning head 101. Under normal use, the cleaning drum 140 normally needs to be taken out for cleaning once a month, and the trash box 152 needs to be taken out for cleaning once a week. The trash box 152 is arranged below the cleaning drum 140 and taken out from the side, so that the trash box 152 and the cleaning drum 140 can be taken out and cleaned separately without affecting each other.

[0065] Since the trash box 152 is arranged below the cleaning drum 140, it is the main body of the trash box and does not need a cover plate for sealing. In addition, the trash box is arranged below the drum, which reduces the size of the cleaning head 100 in the direction from the front wheel 181 to the rear wheel 182. Therefore, the cleaning head 100 is more compact. In the cleaning head 100, the upper shell 191 covers the cleaning drum 110 and the cleaning drum 140 as a whole and can be opened in the direction from the front wheel 181 to the rear wheel 182. A second locking device is arranged on the shell 190 of the cleaning head 100 for locking the trash box 152. The cleaning drum 140 adopts a brush drum structure. The cleaning drum 110 adopts a sponge drum.

[0066] like Figure 4As shown, an arc-shaped garbage channel A is formed between the shovel bar and the cleaning roller. The gap between the arc-shaped garbage channel A and the cleaning roller 10 gradually decreases from the outside to the inside, and the gap can also gradually increase. The side wall of the arc-shaped garbage channel A is provided with a plurality of stop bars A2 for stopping solid garbage, and the upper side of the stop bar A2 forms a solid garbage stopping area with the arc-shaped garbage channel A. The arc-shaped garbage channel located in the solid garbage stopping area is provided with a solid garbage grading channel A1 connected to a garbage collection device, that is, the solid garbage grading channel A1 is connected to the solid garbage stopping area, and one end of the solid garbage grading channel A1 is connected to the solid garbage stopping area, and the other end is connected to the garbage box 152. Due to the solid garbage stopping area formed by the stop bar A2 and the arc-shaped garbage channel A, the arc-shaped garbage channel A entering through the cleaning roller can be better collected, and the granular solids are prevented from being affected by their gravity and the force between the arc-shaped garbage channel A and the cleaning roller, and staying in the arc-shaped garbage channel A for a long time, affecting continuous cleaning.

[0067] Figure 5 A three-dimensional view of a brush roller according to an exemplary embodiment of the present application is shown. Figure 4 As shown, according to an exemplary embodiment of the present application, the cleaning roller 140 may be a brush roller. The surface of the brush roller is covered with V-shaped arranged hairs.

[0068] Fig. 6A A schematic diagram of assembling a brush roller according to an exemplary embodiment of the present application is shown.

[0069] like Fig. 6A As shown, during the assembly process of the cleaning head 100, the upper housing 191 integrally covered by the cleaning roller 110 and the cleaning roller 140 can be opened in the direction from the front wheel to the rear wheel. The cleaning roller 110 can be separated from or loaded into the cleaning head 100 in the direction of the arrow in the figure. The cleaning roller 140 can be lifted up and removed or loaded downward into the cleaning head 100 by a handle 142 provided at one end of the cleaning roller 140. The garbage box 152 can be pulled out or loaded from the side of the cleaning head 100 in the direction of the arrow in the figure, so as to facilitate the removal of garbage from the garbage box 152.

[0070] Figure 6B A schematic diagram of assembling a brush roller according to an exemplary embodiment of the present application is shown.

[0071] like Figure 6BAs shown, the brush roller includes non-linearly arranged implanted hairs 142 arranged on the surface of the brush roller and a handle 142 arranged at one end of the brush roller and connected to the shell. The upper shell 191 covering the entirety can also be opened in the direction from the rear wheel to the front wheel. The cleaning roller 140 can be directly arranged on the openable upper shell 191 and connected to the upper shell 191, without the need to separately set up an openable first cover plate. When the upper shell 191 is opened, the cleaning roller 140 is removed from the cleaning head cavity, making it easier to clean and disassemble the cleaning roller 140. Figure 7 A schematic diagram of a cleaning head water path according to an exemplary embodiment of the present application is shown.

[0072] like Figure 7 As shown, the self-cleaning cleaning head housing provided by the present application is provided with a transfer filter bin 160 and a water tank (not shown in the figure). The water tank is a semi-enclosed frame-type water tank structure, which is arranged on the side of the cleaning drum. The open end of the water tank 196 is connected to the Figure 3 The water pressure rod 120 shown in the figure is connected to the water sealing bar 130. The water pressure plate, the water sealing bar and the surface of the cleaning roller 110 form a water storage space connected to the water tank, which gathers and drains the sewage squeezed out of the cleaning roller 110 to the water storage space, and then gathers to the transfer filter bin 160 through the water tank. A water tank cover 195 is provided on the cleaning head shell to seal the water tank. When clean water is injected into the cleaning head by a water pump, the cleaning roller 110 and the water tank can be flushed. The sewage enters the transfer filter bin 160 through the flow channel of the water tank. A filter box is provided in the transfer filter bin 160 to filter the garbage in the sewage. The filter box can be taken out from the transfer filter bin 160 to facilitate the cleaning of the garbage therein.

[0073] It should be further explained that the filter net for filtering sewage can be set in the water tank structure or in the transfer filter bin, and this application does not limit this. In order to prevent small garbage from clogging the sewage waterway, the filter net needs to be taken out and cleaned regularly. The method of setting the filter net in the transfer filter bin allows the user to easily take out the filter net from the cleaning head for cleaning, which greatly improves convenience.

[0074] like Figure 7 As shown, the cleaning head provided by the present application also includes a sewage outlet 161 and a clean water inlet 197. The clean water inlet 197 is arranged on the housing of the cleaning head, and clean water is transported to the cleaning drum through a clean water channel 198 arranged on the housing. The sewage outlet 161 is arranged on the housing and connected to the transfer filter bin 160, and can also be directly arranged on the transfer filter bin 160 to discharge the filtered sewage in the transfer filter bin 160 out of the cleaning head.

[0075] Figure 7 A perspective view of a cleaning tool according to an exemplary embodiment of the present application is shown.

[0076] According to the second aspect of the present application, a cleaning tool is also provided. Figure 7 As shown, the cleaning tool 200 includes a cleaning head 100, a water tank assembly 300 and a handle assembly 400. The water tank assembly 300 is connected to the cleaning head 100, and the handle assembly 400 is connected to the water tank assembly 300.

[0077] like Figure 8 and Fig. 9 As shown, the transfer filter chamber 160 includes a chamber body (not shown in the figure) and a filter plate 160A that divides the chamber body into two chambers, and a plurality of filter holes (not shown in the figure) are distributed on the filter plate 160. The garbage cleaned by water washing from the cleaning drum 110 is filtered through the filter holes to prevent it from entering the water washing flow path and causing magnetic blockage to the water washing flow path.

[0078] The water pressure plate (as shown in the figure) includes a first contact portion arranged above the cleaning roller and in contact with the surface of the cleaning roller and a second contact portion in contact with the surface of the roller. The second contact portion is provided with an extension portion and a water blocking portion in a direction different from the extension portion. Fig.10 A stereoscopic view of a cleaning tool according to an exemplary embodiment of the present application is shown. The cleaning tool is provided with a water tank assembly and a cleaning head connected to the cleaning tool, wherein the cleaning head adopts the structure of the above embodiment and is not described in detail.

[0079] like Fig.11 As shown, the water tank assembly 300 includes a water tank 310 and a connecting component 320. The water tank 310 is detachably mounted on the connecting component 320 through a locking tongue structure 301 and a key structure 302. A handle 303 may also be provided on the water tank 310 for easy installation and removal.
