[0002] The present invention relates to the technical field of cleaning mechanical structures, and in particular to a mopping and sweeping integrated cleaning device. Background Art

[0003] With the development of modern technology, there are many kinds of cleaning equipment, including brooms, mops, floor wipes and vacuum cleaners. For consumers, the scenarios in which cleaning equipment is used are diverse, and relying solely on a single sweeping or mopping method is usually not enough to achieve a thorough cleaning of the floor. In order to better adapt to the cleaning effects in different scenarios, cleaning equipment is usually equipped with two common cleaning methods, so sweeping and mopping cleaning methods have gradually become standard equipment. However, existing sweeping and mopping cleaning equipment requires constant washing during use, which not only brings inconvenience to use, but also affects cleaning efficiency.

[0051] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0052] The present invention relates to a cleaning device that can be used to clean floors, especially small, smooth and flat floors, such as home and kitchen floors. The cleaning device of the present invention is particularly suitable for cleaning mixed garbage containing dry garbage, wet garbage, and viscous materials such as noodles, porridge, and tomato sauce.

[0053] The dry garbage mentioned in the present invention specifically refers to granular garbage, such as fruit peels, melon seed shells, rice grains, paper scraps, etc.

[0054] Wet garbage refers to liquid garbage, such as water, beverages, etc.

[0055] Sticky garbage (or sticky garbage) includes soup, stew, porridge, ketchup, chocolate sauce and other garbage with a certain viscosity.

[0056] Other garbage also has such as dust, ground imprint etc., also is the cleaning object of the present invention.

[0057] Figure 1 Figure 17 shows a mop-and-sweep cleaning device 100 according to the present invention. The mop-and-sweep cleaning device comprises a cleaning component and a sewage collection component for collecting sewage after cleaning. The sewage collection component comprises a sewage collection mechanism for collecting sewage after cleaning the cleaning component and a sewage collection mechanism for centralizing the collected sewage. The sewage collection mechanism comprises a scraping bar that contacts the surface of the cleaning component. The contact area between the scraping bar and the cleaning component surface is a curved surface or arc.

[0058] Specifically, the sewage collection mechanism includes a scraper bar that contacts the surface of the cleaning component, and the contact area between the scraper bar and the surface of the cleaning component is a curved surface or arc. The sewage collection mechanism includes a water pressure rod that squeezes water out of the cleaning component and a scraper bar that contacts the surface of the cleaning component. The scraper bar includes a friction portion and a drainage portion that directs the water squeezed out by the water pressure rod to the sewage collection mechanism. The sewage collection mechanism includes a sewage pump whose water inlet is connected to the drainage portion pipeline, and the water outlet of the sewage pump is connected to the sewage tank. A filtering mechanism is provided at the front end of the sewage pump inlet. The cleaning component includes a drum and a shovel bar with a gap between the drum surface and the cleaning surface to flatten the cleaning surface, and a garbage bin that can collect garbage cleaned by the shovel bar. The cleaning component also includes a pressure bar for fixing the shovel bar. The front end of the shovel bar is provided with a curved working surface, and the shovel bar with this curved working surface forms a garbage channel between the shovel bar and the outer circumferential surface of the drum. The cleaned garbage enters the garbage bin through the garbage channel. The cleaning assembly also includes a clean water pump connected to the clean water tank and a nozzle connected to the clean water pump and formed at an angle with the drum. The clean water pump sprays clean water onto the drum surface through the nozzle, and the angle formed by the water discharge direction of the nozzle and the drum is preferably 5-30 degrees. Because the water discharge direction of the nozzle forms a certain angle with the drum, the clean water discharged from the nozzle can reach a larger area, increasing the area of dirt on the drum to be cleaned. At the same time, the angle can separate dirt on the drum surface from the drum, provide power for the dirt to move, and quickly leave the drum, achieving a better cleaning effect on the drum surface, preventing dirt on the drum from contacting the cleaning surface again, and also improving cleaning efficiency.

[0059] The cleaning device can also rotate and open a movable guard plate as needed, and the movable guard plate is partially covered on the surface of the drum. When the movable guard plate is opened, the minimum distance between the movable guard plate and the front edge of the shovel blade is greater than the diameter of the drum. The drum is a sponge drum, and can also be made of an elastic material that also has a water-absorbing function.

[0060] During use, the scraper bar can form an arc or line of contact with the surface of the cleaning component, which can better concentrate the wastewater after cleaning the cleaning component, making it easier to remove it from the sponge roller, improving wastewater cleaning efficiency and thus improving cleaning efficiency. At the same time, the contact arc or line disperses the force, which can also reduce the resistance of the cleaning component when cleaning wastewater, reducing energy loss during cleaning.

[0061] In order to better illustrate the structure, working principle and technical effects of the present invention, specific embodiments are given to further illustrate.

[0062] The cleaning device 100 includes a handle assembly 110, a sewage tank assembly 120 and a cleaning assembly 130. The sewage tank assembly 120 is connected to the handle assembly 110 and the cleaning assembly 130 respectively.

[0063] like Figure 2As shown in FIG. 4 , the cleaning assembly 130 includes a cleaning head body 131 and a roller 132 mounted on the cleaning head body 131 , a clean water tank 133 , a filter device 134 , a trash bin 135 , a shovel bar 136 , a scraper bar 137 and a water pressure rod 138 . The roller 132 is usually made of sponge material, but other water-absorbing and bendable materials can also be used.

[0064] The roller 132 comprises an inner layer of hard rubber and a sponge layer surrounding the hard rubber. The end of the hard rubber is secured to the cleaning head body 131 via a bearing or other connector. The roller drive mechanism drives the hard rubber to rotate about its axis through the roller transmission mechanism, which in turn drives the roller to rotate, causing the roller surface to move in a circular motion.

[0065] The trash bin 135 is located between the drum 132 and the clean water tank 133. Optionally, the trash bin 135 can be detachably mounted on the cleaning head body 131. The shovel bar 136 has a curved working surface that forms a trash channel with the outer circumference of the drum 132, through which trash enters the trash bin 135. Optionally, the scraper bar 137 may include a friction portion and a drainage portion (not shown), wherein the friction portion and the drainage portion respectively interfere with (i.e., squeeze) the drum 132. The friction portion scrapes off trash adhering to the drum, and the scraped trash enters the trash bin 135 under its own weight. The drainage portion prevents water squeezed out by the water pressure rod 138 from flowing along the drum 132 to the ground. The drainage portion, the drum 132, the water pressure rod 138, and the cleaning head body 131 together form a water tank A. The cleaning head body 131 is provided with a water tank inlet and a water tank outlet (not shown). The water tank inlet is connected to the clean water tank 133, and the water tank outlet is connected to the dirty water tank body 122. Clean water from the clean water tank 133 enters the water tank A through the water tank inlet and is used to clean the roller 132. The dirty water squeezed by the water pressure rod 138 enters the filter device 134 through the water tank outlet. The filtered dirty water enters the dirty water tank body 122.

[0066] In this embodiment, the filter device 134 is a filter box, such as Figure 2 As shown, it is located on one side of the clean water tank 133. In this embodiment, the sewage flowing out of the water tank outlet can flow into the filter box 134 by gravity. To facilitate cleaning of the sewage channel, in this embodiment, the sealing cover 131a of the sewage channel is removable. Optionally, the filter box 134 can be removably mounted on the cleaning head body 131.

[0067] The clean water in the clean water tank 133 is used to clean the drum 132. A water pump can be used to pump the clean water from the clean water tank 133 into the water tank A. The clean water tank 133 is fixed to the cleaning head body 131. This avoids the need for a water check mechanism, reduces structural complexity, and reduces the risk of water leakage at the tank interface. Optionally, the clean water tank 133 and the cleaning head body 131 are integrally formed. In this embodiment, the cleaning tank 133 is provided with a clean water tank lid 133a. Opening the lid allows the addition of clean water to the clean water tank 133.

[0068] The sewage tank assembly 120 includes a sewage tank body 121 and a sewage tank casing 122. The sewage tank casing 122 is used to hold sewage. Optionally, the sewage tank casing 122 can be detachably mounted on the sewage tank body 121 to facilitate pouring out the sewage.

[0069] In this embodiment, the front end of the cleaning head body is equipped with a curved, movable guard plate 131b. To remove the roller 132, simply rotate the guard plate 131b clockwise. After installing the roller 132, rotate the guard plate 131b counterclockwise to close it. This function keeps the roller 132 moisturized, extending its moisture retention time. It also provides some protection against collisions.

[0070] like Figure 11 and Figure 12 As shown, the sewage tank body 122 is equipped with a lid 122a, a sealing ring 122b, a locking tongue 122c, a button 122d, a handle 122e, a water extraction port 122f, and an air extraction port 122g. In this embodiment, the sewage can be discharged from the sewage tank body 122 by opening the lid 122a. The sewage enters the sewage tank body 122 through the water extraction port 122f. The sewage pipe (not shown) is directly connected to the filter box 134. An air pump is used to pump the filtered sewage from the filter box 134 through the sewage pipe and into the sewage tank body 122.

[0071] When using the cleaning device of this embodiment to clean dry garbage from the floor, as drum 132 rolls over the floor, the dry garbage particles on the floor compress and deform the sponge layer of drum 132. The deformation of the sponge layer wraps around the dry garbage particles, separating them from the floor and allowing them to rotate with drum 132. When the drum reaches the position of scooping bars 136, the dry garbage particles leave the floor and, squeezed by scooping bars 136, continue to rotate with drum 132. When the drum passes scooping bars 136 and reaches the entrance of trash bin 135, the compression of scooping bars 136 is removed, and the sponge layer recovers its deformation, releasing the dry garbage particles it had wrapped around it. The garbage then enters trash bin 135 under its own weight and elastic force.

[0072] Some small particles of dry garbage may not be able to bounce into the trash bin 135 due to the elastic deformation of the sponge layer. They can also be scraped off by the friction part of the scraper 137 and fall into the trash bin 135. If they have not been removed from the drum 132, they will be transferred to the water tank A as the drum 132 rotates. The water flows in the water tank A, forming a flushing force, which can also remove the garbage from the surface of the drum 132. In addition, the water pressure rod 138 also interferes with the drum 132, and the garbage can also be scraped off here. The garbage removed from the water tank A and the water pressure rod 138 flows into the filter box 134 with the water flow. After filtration, the sewage is sucked into the sewage tank body 122, and the garbage remains in the filter box 134 waiting to be cleaned. Through the above settings, dry garbage can be removed from the ground very cleanly without clogging the device.

[0073] When using the cleaning device of this embodiment to clean wet garbage, the sponge layer of the drum 132 absorbs the wet garbage. The wet garbage is then transported along the drum 132 to the water tank A. Water flows through the water tank A, and the water pressure rod 138 squeezes the sponge layer of the drum 132. The wet garbage is released from the sponge layer and flows into the filter box 134. It is then sucked into the sewage tank 122.

[0074] When using the cleaning device of this embodiment to clean sticky garbage, the sticky garbage adheres to the sponge layer of drum 132 and partially penetrates the sponge layer of drum 132. As drum 132 continues to rotate, the friction portion of scraper bar 137 picks up some of the sticky garbage adhering to the surface of drum 132. The scraped garbage then flows into trash bin 135 under its own weight. The sticky garbage that cannot be scraped off reaches water tank A. Water flowing in water tank A washes away the sticky garbage adhering to the surface of drum 132. Furthermore, water pressure rod 138 also scrapes away sticky garbage adhering to the surface of drum 132. The combined action of the water flow and water pressure rod 138 releases the sticky garbage that has penetrated the sponge layer, while the sticky garbage adhering to the sponge layer is also removed and carried along by the water flow into filter box 134. Some of the garbage is retained by filter box 134, and the filtered wastewater is then pumped into the wastewater tank body 122.

[0075] Figure 13 Figure 16 shows another cleaning device 200 of the present invention. It includes a handle assembly 210, a sewage tank assembly 220, and a cleaning assembly 230. The sewage tank assembly 220 is connected to the handle assembly 210 and the cleaning assembly 230, respectively.

[0076] The cleaning assembly 230 includes a cleaning head body 231 and a roller 232 mounted on the cleaning head body 231 , a clean water tank 233 , a filter device 234 , a water storage tank 235 , a shovel bar 236 , a scraper bar 237 , a water pressure rod 238 and a nozzle.

[0077] The roller 232 is the same as the roller 132 and will not be described again here.

[0078] and Figure 1 Unlike the embodiment shown in Figure 12, this embodiment lacks a trash can. Instead, a water tank 235 is located between the drum 132 and the clean water tank 133. A scraper 237 and a water pressure rod 238 are located at either end of the opening of the water tank 235. In other words, the water tank 235, scraper 237, and water pressure rod 238 form a closed water storage space. During use, the cleaning device moves back and forth, causing the water in the water tank 235 to slosh back and forth, creating a turbulent state. This swirling water not only flushes the drum 232 but also maintains a certain humidity within the drum 232, thereby enhancing the cleaning effect.

[0079] In this embodiment, the filter device 234 is a filter screen. Figure 14 As shown, filter screen 234 is located within water tank 235. A handle 235a is provided at the top of water tank 235, and filter screen 234 is connected to handle 235a. Pulling handle 235a allows filter screen 234 to be removed, thereby clearing out the garbage. Scooping bar 236 has a curved working surface, which forms a garbage channel with the outer circumference of drum 232. Garbage enters water tank 235 through the garbage channel and scraping bar 237.

[0080] The scraper 237 includes a friction portion 237a and a drainage portion 237b. Figure 9 The friction portion 237a interferes with the roller 232. The surface of the drainage portion 237b is inclined, and can drain the water squeezed out by the water pressure rod 238 into the water storage tank 235.

[0081] In this embodiment, there are two nozzles: a first nozzle 239a and a second nozzle 239b. The first nozzle 239a is aligned with the drum 232, while the second nozzle 239b is aligned with the drainage portion 237b. Specifically, the first nozzle 239a can spray clean water from the clean water tank 233 onto the drum 232, thereby flushing the drum 232. The second nozzle 239b can spray clean water from the clean water tank 233 onto the drainage portion 237b, facilitating the flushing of trash attached to the drainage portion 237b into the water tank 235. In other embodiments of the present invention, the nozzles can also be aligned with the water tank 235, flushing trash attached to the walls of the water tank 235 onto the filter 234. The nozzle alignment position can be set according to actual conditions.

[0082] The clean water in the clean water tank 233 is used to clean the drum 232. A water pump can be used to pump clean water from the clean water tank 133 to the first nozzle 239a and the second nozzle 239b. Optionally, the clean water tank 233 and the cleaning head body 131 are integrally fixed (e.g., integrally molded). This avoids the need for a water check mechanism, reduces structural complexity, and reduces the risk of water leakage at the tank interface. In this embodiment, the cleaning tank 133 is provided with a clean water tank lid 133a. Opening the lid allows fresh water to be poured into the clean water tank 133.

[0083] Similarly, in this embodiment, an arc-shaped movable guard plate can also be provided to facilitate the disassembly and moisturizing of the roller 232 and to provide anti-collision protection.

[0084] The sewage tank assembly 220 includes a sewage tank body 221, a sewage tank casing 222, a clean water pump 223, an air pump 224 and required water pipes. The sewage tank casing 222 is used to hold sewage. Figure 1 - Figure 12 In the illustrated embodiment, the sewage tank housing 222 is removably mounted on the sewage tank body 221 to facilitate wastewater removal. The detailed structure of the sewage tank housing 222 is identical to that of the sewage tank housing 122 and will not be further described here. It should be noted that the water storage tank 235 of this embodiment has a water storage function, so the water within it does not need to be pumped into the sewage tank assembly 220 in real time, without affecting the cleaning effect. In other words, the water change cycle can be adjusted according to actual conditions, thereby conserving water.

[0085] like Figure 16 and Figure 17 As shown, clean water in clean water tank 233 is pumped out of clean water inlet pipe 223a by clean water pump 223 and delivered to first nozzle 239a and second nozzle 239b through clean water outlet pipe 223b. When sewage tank body 222 is mounted to sewage tank body 221, water storage tank 235 is connected to sewage tank body 222. Sewage filtered by filter 234 is then pumped from sewage pipe 222a into sewage tank body 222 by air pump 224.

[0086] When using the cleaning device of this embodiment to clean dry garbage from the floor, as drum 232 rolls over the floor, the dry garbage particles on the floor compress and deform the sponge layer of drum 232. The deformation of the sponge layer wraps around the dry garbage particles, separating the dry garbage particles from the floor and allowing them to rotate with drum 232. When the dry garbage particles reach the position of scooping bars 236, they leave the floor and, squeezed by scooping bars 236, continue to rotate with drum 232. When they pass scooping bars 236 and reach scraping bars 237, the compression of scooping bars 236 is removed, and the sponge layer recovers its deformation, releasing the dry garbage particles that it had wrapped around it. These particles are then driven into water tank 235 by scraping bars 237.

[0087] Some small particles of dry garbage may not be able to remain attached to the sponge layer, and the scouring force of the agitated water or the scouring force of the nozzle water and the water pressure rod 238 can remove the garbage from the surface of the drum 232 and enter the water storage tank 235. The filtered sewage is sucked into the sewage tank body 222.

[0088] When using the cleaning device of this embodiment to clean wet garbage, the sponge layer of drum 232 absorbs the wet garbage. The wet garbage then travels along drum 232 to water pressure rod 238, which squeezes the sponge layer of drum 232. The wet garbage is released from the sponge layer and flows into water storage tank 235. The filtered wastewater is then pumped into wastewater tank 222.

[0089] When using the cleaning device of this embodiment to clean sticky waste, the sticky waste adheres to the sponge layer of drum 232 and partially penetrates the sponge layer of drum 232. As drum 232 continues to rotate, the friction of scraper bar 237 scrapes off some of the sticky waste adhering to the surface of drum 232. The scraped waste is removed from the surface of drum 232 by the combined action of agitated water or water sprayed from the nozzle and water pressure rod 238 and enters water storage tank 235. The filtered wastewater is then pumped into wastewater tank body 222.

[0090] The present invention utilizes the "water-dust circulation" cleaning technology to achieve self-cleaning of the drum, and combines sweeping, mopping, washing and twisting together, which greatly facilitates users and can achieve very good cleaning effects.

Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
