Description

Technical Field

[0001] This invention relates to the field of floor scrubbing machine technology, specifically to a dry-wet separation floor brush structure with an integrated wastewater tank. Background Technology

[0002] In the cleaning industry, floor scrubbers, as a highly efficient cleaning device, are widely used in various places, such as commercial spaces, office areas, and home environments, providing people with convenient cleaning solutions.

[0003] For example, patent number CN115227155B discloses a floor scrubbing machine, which includes a floor scrubbing device, a scraper device, a base, a blower device, a column, a wastewater tank, a clean water tank, and a battery device; the floor scrubbing device and the scraper device are both located at the bottom of the base; the scraper device is located on the rear side of the floor scrubbing device and is connected to the wastewater tank through a wastewater pipe, and the wastewater tank and the clean water tank are detachably connected to the front and rear sides of the column, respectively.

[0004] In the above structure, the floor scrubbing device and the wastewater tank are positioned far apart. The wastewater tank needs to be connected to the scraper device via a wastewater pipe. Due to the long length of the wastewater pipe, it cannot be guaranteed that all wastewater will be completely discharged after each cleaning operation. Wastewater easily accumulates inside the wastewater pipe, and over time, this stagnant wastewater will gradually breed a large number of bacteria, leading to odor problems. In addition, the above-mentioned floor scrubbing machine cannot achieve dry and wet separation of garbage. Moist air can easily enter the motor, and the fan may spray wastewater during machine operation, which will shorten the product's lifespan. Summary of the Invention

[0047] Combination Figures 1-16 As shown, this invention provides a dry-wet separation floor brush structure with an integrated sewage tank, including a floor brush body 1 and a roller brush 2 rotatably mounted on the front end of the floor brush body 1. A sewage tank 3 is installed on the floor brush body 1, and the sewage tank 3 is divided into a sewage area 301 and a dry waste area 302. The sewage area 301 is used to store sewage, and the dry waste area 302 is used to store dry waste. A negative pressure device 4 connected to the sewage area 301 and an exhaust device 5 connected to the dry waste area 302 are installed inside the floor brush body 1. A filter element 31 is installed inside the dry waste area 302 to filter the dry and wet waste, thereby separating the sewage and dry waste. The sewage area 301 is connected to the dry waste area 302 through a guide channel 303, and the sewage in the dry waste area 302 can flow into the sewage area 301 through the guide channel 303. A waste suction port 304 is provided on the side of the sewage tank 3 facing the roller brush 2, and the waste suction port 304 is connected to the dry waste area 302.

[0048] During floor cleaning, the dry and wet waste is drawn into the dry waste area 302 by the coordinated operation of the negative pressure device 4 and the exhaust device 5 through the garbage suction port 304. The filter element 31 in the dry waste area 302 filters the waste, separating the dry waste and the sewage. The dry waste produced after filtration is left in the dry waste area 302, and the sewage produced after filtration flows into the sewage area 301 through the guide channel 303.

[0049] This integrated wastewater tank features a dry-wet separation design for the floor brush, innovatively integrating the wastewater tank onto the main body of the floor brush. This eliminates the need for the long wastewater pipe connecting the cleaning device and the wastewater tank found in traditional floor scrubbers. This optimized layout prevents wastewater from accumulating in the pipe at the source. Traditional floor scrubbers suffer from wastewater residue due to long pipes, leading to bacterial growth and odor. This design effectively solves this long-standing problem for users, creating a fresh and healthy cleaning environment and improving the hygiene performance of the floor scrubber.

[0050] The wastewater tank features a dry-wet separation design, a major highlight of this product. During the cleaning process, this design automatically and effectively separates moisture from the waste, storing dry waste and wastewater in different areas. On one hand, it prevents humid air from entering the blower, preventing blower malfunctions due to moisture and extending its lifespan. On the other hand, it eliminates the phenomenon of wastewater being sprayed out by the blower during machine operation, protecting critical components such as the motor, thus significantly extending the overall lifespan of the equipment. Furthermore, the automatic separation of dry and wet waste facilitates subsequent waste sorting and processing, aligns with environmental protection principles, and enhances the product's social value.

[0051] In some embodiments, such as Figure 4 as well as Figures 6 to 8 As shown, a dry waste box 32 is detachably installed in the dry waste area 302. The dry waste box 32 has a square box-like structure and is used to receive dry and wet waste entering the dry waste area 302. Filter elements 31 are installed at the bottom and / or sides of the dry waste box 32. The dry waste produced after filtration remains inside the dry waste box 32. The dry waste box 32 can be pulled out to the outside of the sewage tank 3 for easy cleaning of the dry waste inside the dry waste box 32. In this embodiment, to improve the filtration effect and efficiency, filter elements 31 are installed at the bottom and on the three sides of the dry waste box 32.

[0052] During the cleaning process, through the coordinated operation of the negative pressure device 4 and the exhaust device 5, dry and wet waste are initially drawn in through the waste inlet 304 and collected in the dry waste box 32. The dry and wet waste are first initially separated in the dry waste box 32, and the wastewater is filtered to the bottom of the box using the filter element 31 (filter screen). At the same time, the negative pressure device 4 (vacuum pump) creates a vacuum negative pressure in the wastewater area 301. With the help of the siphon effect generated by this negative pressure, the wastewater in the dry waste area 302 is automatically drawn into the wastewater area 301 through the guide channel 303. After the separation is completed, the negative pressure device 4 (vacuum pump) and the exhaust device 5 (fan) work through their respective air intake channels to establish a pressure difference in the system, thereby efficiently expelling the air from the two independent areas.

[0053] In some embodiments, such as Figure 4 , Figure 7 and Figure 9As shown, a wastewater tank 3 has an inlet 305 on one side that communicates with the dry waste area 302. The dry waste container 32 can be inserted into or removed from the dry waste area 302 through the inlet 305. At least one first locking head 321 is retractably mounted on the dry waste container 32. In this embodiment, retractable first locking heads 321 are symmetrically mounted on both sides of the dry waste container 32, and locking slots 306 that engage with the first locking heads 321 are symmetrically provided at the inlet 305. At least one toggle button 322 is slidably mounted on the dry waste container 32. The toggle button 322 is connected to the first locking head 321. In this embodiment, there are two toggle buttons 322, each corresponding to one of the two first locking heads 321. The first locking heads 321 and the toggle buttons 322 are an integral structure. A spring is installed between the toggle button 322 and the dry waste container 32, and the spring always tends to make the first locking head 321 move outward. When disassembling the dry waste container 32, bring the two knobs 322 together towards the center. The knobs 322 will cause the first locking head 321 to retract, disengaging the first locking head 321 from the first locking slot 306. At this point, the dry waste container 32 can be pulled out directly.

[0054] This design features a removable dry waste bin in the dry waste area, with a filter installed on the bin. This greatly simplifies the cleaning of dry waste. During the cleaning process, the filter filters the incoming waste, leaving the dry waste inside the bin. When cleaning is needed, users can easily remove the dry waste bin by simply sliding a knob on it, eliminating complicated procedures, reducing the difficulty of cleaning dry waste, and improving cleaning efficiency.

[0055] In some embodiments, such as Figure 12 and Figure 13 As shown, a guide pipe 307 is installed at the connection between the sewage area 301 and the dry waste area 302, and a guide channel 303 is installed inside the guide pipe 307. The lower end of the guide pipe 307 is connected to the bottom of the dry waste area 302, and the upper end of the guide pipe 307 is connected to the sewage area 301. During operation, sewage from the bottom of the dry waste area 302 enters the guide pipe 307 from the lower end and flows along the guide channel 303, eventually flowing into the sewage area 301 from the upper end of the guide pipe 307.

[0056] In some embodiments, such as Figure 6 , Figure 10 and Figure 11 As shown, a transfer channel 33 is fixed in the sewage area 301. The transfer channel 33 is used to connect the garbage suction port 304 and the dry garbage area 302. A connecting port 308 is provided at the connection between the sewage area 301 and the dry garbage area 302. The dry garbage box 32 corresponds to the connecting port 308 and can receive dry and wet garbage at the connecting port 308. One end of the transfer channel 33 is connected to the garbage suction port 304, and the other end of the transfer channel 33 is connected to the connecting port 308.

[0057] In this structure, the sewage zone and the dry waste zone are connected by a guide pipe and an internal guide channel. A transfer channel is set in the sewage zone to connect the garbage suction port and the dry waste zone. This design optimizes the flow path of sewage and garbage, ensures a smooth and efficient dry and wet separation process, and improves the overall cleaning effect.

[0058] In some embodiments, such as Figures 1 to 4 As shown, to facilitate the cleaning of sewage and dry waste in the sewage tank 3, the sewage tank 3 is detachably installed inside the brush body 1. The inner side of the roller brush 2 forms a receiving groove 101 for accommodating the sewage tank 3, and the sewage tank 3 is detachably installed inside the receiving groove 101. An exhaust port 102 and a suction port 103 are respectively provided on both sides of the receiving groove 101. An exhaust port 309, which can communicate with the exhaust port 102, is provided at the sewage area 301, and a suction port 310, which can communicate with the suction port 103, is provided at the dry waste area 302. When the sewage tank 3 is installed inside the receiving groove 101, the exhaust port 309 is connected to the exhaust port 102, and the suction port 310 is connected to the suction port 103. (See reference...) Figure 10 To ensure structural feasibility, the connecting pipe of the exhaust port 309 inside the sewage area 301 is relatively high to prevent sewage from being directly sucked away by the connecting pipe and to ensure the storage capacity of sewage in the sewage area 301; the step of the suction port 310 inside the dry waste area 302 is relatively high to prevent the sewage generated after filtration from being directly sucked away through the suction port 310, thus ensuring structural feasibility.

[0059] In some embodiments, such as Figure 4 , Figure 5 , Figure 10 and Figure 11 As shown, the sewage tank 3 is provided with a sewage outlet 312 communicating with the sewage area 301. The sewage outlet 312 is used to discharge the sewage stored in the sewage area 301. The sewage tank 3 is equipped with an openable sewage cover 36, which is used to block the sewage outlet 312. When working, the sewage cover 36 is closed to block the sewage outlet 312. When cleaning the sewage, the sewage cover 36 can be opened. One end of the sewage cover 36 is hinged to the sewage tank 3, and the other end of the sewage cover 36 is locked to the sewage tank 3 via a snap-fit ​​member 37. The middle part of the snap-fit ​​member 37 is hinged to the sewage tank 3. One end of the snap-fit ​​member 37 is provided with a snap-fit ​​part for locking the sewage cover 36, and the other end of the snap-fit ​​member 37 is provided with a pressing part. By pressing the pressing part, the snap-fit ​​member 37 can be rotated, thereby disengaging the snap-fit ​​part from the sewage cover 36. At this time, the sewage cover 36 can be rotated open. This structure features a drain outlet on the wastewater tank, equipped with an openable drain cover that can be opened and closed via a snap-fit ​​mechanism, facilitating the discharge of wastewater from the tank and further enhancing the ease of cleaning and maintenance.

[0060] In some embodiments, such as Figure 6 and Figure 11 As shown, the sewage tank 3 includes a sewage tank body 34 and a sewage tank cover 35 that covers the sewage tank body 34. The sewage tank cover 35 is fixed to the sewage tank body 34 by multiple screws. The sewage area 301, the dry waste area 302, and the waste suction inlet 304 are all arranged on the sewage tank body 34. The negative pressure device 4 is a vacuum pump, the exhaust device 5 is a fan, and the filter element 31 is a filter screen.

[0061] In some embodiments, such as Figure 2 , Figure 4 , Figure 6 and Figure 11 As shown, the sewage tank 3 is equipped with at least one retractable second buckle 311, and the receiving groove 101 is provided with a retaining seat 104 that can engage with the second buckle 311; wherein, there are four second buckles 311 respectively located at the four corners of the sewage tank 3, and four retaining seats 104 are also respectively located at the four corners of the receiving groove 101. The sewage tank 3 is equipped with a handle 6, which is used to lift the sewage tank 3 out of the receiving groove 101. The second buckle 311 is driven to the handle 6; when the sewage tank 3 is lifted out using the handle 6, the handle 6 drives the second buckle 311 to disengage from the retaining seat 104.

[0062] This structure features a detachable wastewater tank design, securely fixed to the floor brush body via a second latch that tightly engages with the mounting bracket. During floor scrubber operation, this stable connection effectively reduces tank movement and noise, ensuring stable and quiet brush operation and enhancing the user experience. When cleaning the wastewater tank, the handle and second latch mechanism simplify and expedite operation. Lifting the handle causes the four second latches at the four corners of the tank to retract, quickly unlocking and separating the tank from the brush body. This significantly improves tank disassembly and assembly efficiency, allowing users to easily complete cleaning and maintenance tasks.

[0063] In some embodiments, such as Figure 6 , Figure 10 and Figure 11As shown, a first telescopic rod 71, a first drive rod 72, a second drive rod 73, and a second telescopic rod 74 are slidably installed in a U-shape inside the sewage tank 3. The first telescopic rod 71 and the second telescopic rod 74 are parallel and spaced apart. The first drive rod 72 is driven to the first telescopic rod 71, and the second drive rod 73 is driven to the second telescopic rod 74. A handle 6 is installed between the first drive rod 72 and the second drive rod 73. The handle 6 is used to drive the first drive rod 72 and the second drive rod 73 to slide. The first drive rod 72 is used to drive the first telescopic rod 71 to extend and retract, and the second drive rod 73 is used to drive the second telescopic rod 74 to extend and retract. Four second buckles 311 are respectively arranged on the first telescopic rod 71, the second drive rod 73, and the second telescopic rod 74. The first telescopic rod 71 has a second buckle 311 at both ends, the second drive rod 73 has a second buckle 311 at the end connected to the second telescopic rod 74, and the second telescopic rod 74 has a second buckle 311 at the end away from the second drive rod 73.

[0064] In some embodiments, such as Figures 14 to 16 As shown, two pressure blocks 601 are symmetrically and spaced apart on the handle 6. The ends of the first drive rod 72 and the second drive rod 73 are provided with first inclined baffles 721 corresponding to the pressure blocks 601. When the handle 6 rotates, the pressure blocks 601 press down on the first inclined baffles 721, the first drive rod 72 and the second drive rod 73 move closer to the middle, the first telescopic rod 71 and the second telescopic rod 74 retract, and at this time the four second latches 311 retract and disengage from the latch seat.

[0065] like Figure 15 As shown, the end of the first telescopic rod 71 is provided with a first driving block 711, and a second inclined baffle 712 is provided on one side of the first driving block 711; the end of the first driving rod 72 is provided with a first driving groove 722 for accommodating the first driving block 711, and a first inclined push wall 723 adapted to the second inclined baffle 712 is provided in the first driving groove 722. Figure 16 As shown, the way the second drive rod 73 drives the second telescopic rod 74 to move is the same as the way the first drive rod 72 drives the first telescopic rod 71 to move, and will not be described again in this embodiment.
