Description

[0001] This application is a divisional application of Chinese patent application number 202010627499.4, with the invention name “A Cleaning Device”, the contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure belongs to the technical field of cleaning equipment, and in particular, relates to a cleaning head and a cleaning device. Background Art

[0003] With the development of modern technology, there are many kinds of cleaning tools, including brooms, mops, floor wipes and vacuum cleaners, etc. Vacuum cleaners are very common floor cleaning tools, but they are very noisy and very uncomfortable, and their way of cleaning garbage is just to suck the garbage into a garbage box.

[0004] Brooms, mops, and floor scrubbers are sweeping cleaning tools. They typically have a fixed cleaning part, and their cleaning performance depends on its ability to remove and absorb dirt. Since this cleaning part becomes contaminated upon contact with the dirty floor, its cleaning power gradually diminishes during subsequent cleaning. This makes it difficult to achieve a thorough clean, especially when sweeping large areas continuously. Consequently, these cleaning tools require frequent rinsing, which is quite cumbersome.

[0005] For Chinese consumers, sweeping and mopping are both essential for floor cleaning. Sweeping or mopping alone cannot achieve a thorough clean. However, existing sweeping and mopping machines either require constant washing or are complex and expensive, making them prohibitive for ordinary consumers.

[0006] Furthermore, existing floor cleaning tools can only clean dry waste (brooms or vacuum cleaners, etc.) or liquid waste (mops, floor scrubbers, etc.). They are either extremely ineffective at cleaning mixed dry and wet waste, especially sticky waste (such as syrup, ketchup, etc.), or extremely laborious (for example, using a rag requires multiple rinses), effectively rendering them useless. Summary of the Invention

[0031] The clean water in the clean water tank is transported to the water tank through the clean water pipe, and the sewage tank collects sewage in the water tank through the sewage pipe.

[0032] In some embodiments of the present invention, an ozone generator is installed at the lower end of the clean water tank body, and a clean water outlet and an ozone inlet are provided at the bottom end of the clean water tank body. When the clean water tank body is installed on the clean water tank body, the ozone prepared by the ozone generator enters the clean water in the clean water tank body through the ozone inlet.

[0033] In some embodiments of the present invention, a water tank cover is further provided on the clean water tank body.

[0034] In some embodiments of the present invention, the cleaning device further comprises:

[0035] The water pump is arranged between the clean water tank and the clean water inlet to adjust the speed of spraying water onto the drum.

[0036] The beneficial effects of the present invention are as follows:

[0037] The cleaning head of the present invention is provided with at least one water pressure plate. Through the water trough and at least one squeezing operation, when the cleaning device cleans sticky garbage, the sticky garbage adheres to the sponge layer of the drum and partially penetrates the sponge layer of the drum. As the drum continues to rotate and reaches the water trough, clean water flushes the sticky garbage, and the water pressure plate can scrape off the sticky garbage adhered to the drum surface. Under the combined action of the water flow and the water pressure plate, the sticky garbage is removed from the drum surface, and the sticky garbage that has penetrated the sponge layer is released and enters the sewage tank along with the sewage. The drum can be cleaned very cleanly during the mopping and sweeping process, and the frequent use of special cleaning procedures is no longer required. Since the drum is cleaned very cleanly, the floor cleaning efficiency is improved.

[0038] In addition, the cleaning head is provided with an inclined sewage channel through the side wall of the shell. The sewage in the sink flows into the sewage tank from the sewage channel through its own weight and water pressure. The sewage channel can be provided with a sewage channel cover to facilitate users to clean the sewage channel.

[0039] The cleaning head of the present invention is provided with two water pressure plates. Through the two-stage water trough and two-time squeezing setting, when the cleaning device cleans the sticky garbage, the sticky garbage adheres to the sponge layer of the drum and partially penetrates into the sponge layer of the drum. When the drum continues to rotate and reaches the first water trough, the clean water flushes the sticky garbage. The first water pressure plate can scrape off the sticky garbage adhered to the surface of the drum. Under the joint action of the water flow and the first water pressure plate, the sticky garbage is removed from the surface of the drum, and the sticky garbage penetrated into the sponge layer is released. It enters the sewage tank with the sewage. If there is still some that has not been scraped off, the clean water sprayed at the clean water inlet will form a flushing force on the drum surface, and the second water pressure plate can also further scrape off the sticky garbage adhered to the surface of the drum. Under the joint action of the water flow and the second water pressure plate, the sticky garbage penetrated into the sponge layer is released, and the sticky garbage adhered to the sponge layer is also removed and enters the sewage tank with the water flow. The roller is double squeezed and scraped to remove dirt during the mopping and sweeping process, and then flushed by two-stage water tanks, so it can be cleaned very cleanly, eliminating the need for frequent special cleaning procedures. Since the roller is cleaned very cleanly, the floor cleaning efficiency is better.

[0040] The cleaning head of the present invention can successfully flush away small garbage or hair on the surface of the drum without providing a brush by providing the clean water inlet and the purified water inlet.

[0041] The cleaning head of the present invention has a sewage pipe and a clean water pipe on the side wall of the shell. The sewage pipe is respectively connected to the sewage tank and the purified water inlet, and the clean water pipe is respectively connected to the clean water tank and the clean water inlet. The clean water inlet is arranged above the water tank, and the purified water inlet is arranged above the water tank. The sewage tank has a filtering function and can filter solid impurities (garbage, sand, etc.) in the sewage. The purified water obtained after filtration can be directly sucked into the water tank to rinse the drum. The water is recycled, which can greatly save the amount of clean water and avoid the trouble of users frequently adding clean water.

[0042] The cleaning device of the present invention includes a handheld portion, which includes a clean water tank. The clean water tank includes a clean water tank body and a clean water tank casing. The clean water tank casing is detachably mounted on the clean water tank body. An ozone generator is mounted at the lower end of the clean water tank body. The bottom end of the clean water tank casing is provided with a clean water outlet and an ozone inlet. When the clean water tank casing is mounted on the clean water tank body, ozone generated by the ozone generator enters the clean water in the clean water tank casing through the ozone inlet. The clean water flowing out of the clean water tank contains ozone, which can disinfect and sterilize the drum, preventing the drum from becoming moldy and odorous. Furthermore, because the water contains ozone, the floor can also be disinfected and sterilized after the drum is mopped and swept.

[0043] 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.

[0044] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] The present invention relates to a cleaning tool that can be used to clean floors, particularly small, smooth and flat floors such as home and kitchen floors. The cleaning tool is particularly suitable for cleaning mixed garbage containing dry garbage, wet garbage, and viscous materials such as noodles, porridge, and tomato sauce.

[0059] 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.

[0060] Wet garbage refers to liquid garbage, such as water, beverages, etc.

[0061] Sticky garbage (or sticky garbage) includes soup, stew, porridge, ketchup, chocolate sauce and other garbage with a certain viscosity.

[0062] Other garbage also has such as dust, ground imprint etc., also is the cleaning object of the present invention.

[0063] Figure 1 The figure shows a cleaning device provided by the present invention, which includes a cleaning head 100. The cleaning head 100 includes a housing 110, a roller 120, a garbage box 130, and a sewage tank 140. Optionally, the roller 120, the garbage box 130, and the sewage tank 140 are detachably mounted on the housing 110.

[0064] Figure 1 In the illustrated embodiment, the housing 110 is provided with a scooping bar 111 and a water sealing member 112. The scooping bar 111 has a curved working surface, one end of which contacts the ground during operation and the other end is connected to the trash bin 130. A trash channel is formed between the curved working surface and the outer circumference of the drum 120, through which trash removed by the drum 120 enters the trash bin 130.

[0065] Furthermore, the housing 110 is provided with a first water pressure plate 113 and a second water pressure plate 114. The water sealing member 112, the first water pressure plate 113, and the second water pressure plate 114 each interfere with (i.e., squeeze) the drum. The water sealing member 112, the first water pressure plate 113, and the drum 120 collectively form a first water trough A, while the first water pressure plate 113, the second water pressure plate 114, and the drum 120 collectively form a second water trough B.

[0066] Above the sink, the housing 110 is provided with a sink cover 115 , which is convenient for cleaning the sink. Figure 2 A water tank cover 115 of the present invention is shown. Figure 2 In the illustrated embodiment, the first water pressure plate 113 is integrally formed with the water tank cover 115. In other embodiments of the present invention, the first water pressure plate may also be a separate component, which is mounted on the water tank cover by snap-fitting or other means. The water tank cover 115 is also provided with a clean water inlet 115a, which is connected to the clean water tank. In this embodiment, the clean water inlet 115a is located above the second water tank B, and clean water enters the second water tank B from the clean water inlet 115a, thereby rinsing the drum 120. In other embodiments of the present invention, the clean water inlet 115a may also be provided above the first water tank A, and of course, it may also be provided above both the first water tank A and the second water tank B. Optionally, in other embodiments of the present invention, the water tank cover 115 may be made transparent, which makes it easier for the user to observe the condition of the water tank and thus clean the water tank in a timely manner.

[0067] In addition, the second water pressing plate 114 can also be designed to be integrally formed with the front side wall of the housing 110. Of course, the second water pressing plate 114 can also be a separate component, which is mounted on the front side wall of the housing 110 by snap connection or other means.

[0068] The housing 110 is also provided with a first water tank outlet (not shown) and a second water tank outlet (not shown), corresponding to the first water tank A and the second water tank B. The first and second water tank outlets are connected to the sewage tank 140. Optionally, the sidewalls of the housing 110 are provided with inclined sewage channels (not shown), through which sewage in the first and second water tanks flows into the sewage tank 140 through the sewage channels under the force of gravity and water pressure. The sewage channels can be provided with sewage channel covers to facilitate user cleaning.

[0069] Roller 120 comprises an inner layer of hard rubber and a sponge layer surrounding the hard rubber. The ends of the hard rubber are secured to housing 110 via bearings and other connectors. The roller drive mechanism drives the hard rubber to rotate about its axis through the roller transmission mechanism, which in turn drives the roller, causing the roller surface to undergo a circular motion.

[0070] The garbage box 130 and the dirty water tank 140 may be designed to be detachable, that is, the garbage box 130 and the dirty water tank 140 may be detachably mounted on the housing 110 .

[0071] The present invention employs a two-stage water trough. The drum 120 experiences significant interference at the first water pressure plate 113, squeezing out the dirty water within. As the drum 120 continues to rotate, fresh water is sprayed out from the clean water inlet 115a, cleaning the drum 120. The drum 120 then rotates to the second water pressure plate 114, where it again experiences significant interference, cleaning the drum 120 a second time. The dirty water in the first and second water troughs A and B flows into the dirty water tank 140. This two-stage water trough and double squeezing arrangement allows the drum of the present invention to be cleaned exceptionally well during the mopping and sweeping process, eliminating the need for frequent, specialized cleaning procedures.

[0072] Figure 3 Shown is another embodiment of the present invention, in which the cleaning device further includes a handheld portion 200. The handheld portion 200 includes a clean water tank, which includes a clean water tank body 211 and a clean water tank housing 212. The clean water tank housing 212 is detachably mounted on the clean water tank body 211. An ozone generator (not shown) is mounted at the lower end of the clean water tank body 211. The bottom end of the clean water tank housing 212 is provided with a clean water outlet 212b and an ozone inlet 212c. When the clean water tank housing 212 is mounted on the clean water tank body 211, ozone generated by the ozone generator enters the clean water in the clean water tank housing 212 through the ozone inlet 212c. The clean water flowing out of the clean water tank contains ozone, which can disinfect and sterilize the drum 120, preventing it from becoming moldy or smelly. Furthermore, since the water contains ozone, the floor can also be disinfected and sterilized after being mopped with the drum 120.

[0073] Figure 3 In the illustrated embodiment, the clean water tank body 212 is further provided with a water tank cover 212a, through which a user can add clean water into the clean water tank body 212.

[0074] The clean water tank is connected to the clean water inlet 115a. The water pump can be a water pump with adjustable water speed, so as to adjust the speed of spraying water onto the drum 120.

[0075] The housing 110 and the handheld part 200 may be connected via a hinge. Of course, they may also be connected via other means, which is not limited in the present invention.

[0076] Figure 4Another cleaning head of the present invention is shown, which has a sewage pipe 116a and a clean water pipe 116b on a side wall of the housing 110. The sewage pipe 116a is respectively connected to the sewage tank 140 and the purified water inlet, and the clean water pipe 116b is respectively connected to the clean water tank and the clean water inlet 115a. Optionally, the clean water inlet 115a is set above the second water tank B, and the purified water inlet is set above the first water tank A. The sewage tank 140 in this embodiment has a filtering function and can filter solid impurities (garbage, sand, etc.) in the sewage. The purified water obtained after filtration can be directly sucked into the first water tank A to rinse the drum 120. The recycling of water can greatly save the amount of clean water used and avoid the trouble of users frequently adding clean water.

[0077] The clean water inlet 115a is set above the second water tank B, and the purified water inlet is set above the first water tank A. At this time, the water in the first water tank A is filtered sewage, which can wash out hair debris and other stuck garbage, and squeeze out the sewage at the same time; the drum passing through the second water tank B is in an unsaturated state, and the clean water with ozone is absorbed into the inside, sterilizing and precipitating the internal garbage, which is carried away by the water flow, and the drum is deeply cleaned.

[0078] Figures 5 to 7 The figure shows a sewage tank 140 of the present invention that can be detachably mounted on a housing 110. The sewage tank 140 is provided with a filter screen 141, a filter box 142, a water inlet check valve 143, a water outlet check valve 144, a sewage tank lock tongue 145, a sewage tank button 146, and a sewage tank cover 147. The filter screen 141 can be a steel mesh, a nylon mesh, etc., preferably a steel mesh. In this embodiment, there are two filter boxes 142, wherein the filter box body 142a is equipped with filter cotton 142b (such as Figure 6 As shown in FIG. 1 , filter cartridge 142 may contain other filter materials, as long as they can effectively filter the sewage. Sewage from drum 120 undergoes three-stage filtration, using two filter cartridges 142 and a filter screen 141. This removes most of the waste and lightens the color of the sewage. The treated purified water is then pumped back into first tank A for recycling.

[0079] The inlet check valve 143 and the outlet check valve 144 prevent sewage from flowing out of the sewage tank 140 when it is removed from the housing 110. The sewage tank lock 145 and the sewage tank button 146 allow the user to easily remove the sewage tank 140 from the housing 110. In this embodiment, the sewage tank 140 is also equipped with a sewage tank cover 147 to facilitate replacement of the filter cotton 142b and removal of waste from the sewage tank 140.

[0080] When using the cleaning device of the present invention to clean dry garbage from the floor, as the drum 120 rolls over the floor, the dry garbage particles on the floor compress and deform the sponge layer of the drum 120. 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 the drum 120. When the drum 120 reaches the position of the scooping bar 111, the dry garbage particles leave the floor and, squeezed by the scooping bar 111, continue to rotate with the drum 120. When the drum 120 passes the scooping bar 111 and reaches the entrance of the trash bin 230, the compression of the scooping bar 111 is removed, and the sponge layer recovers its deformation, releasing the dry garbage particles it had wrapped around it. The garbage then enters the trash bin 230 under the action of its own weight and elastic force.

[0081] Some small particles of dry waste may not be able to bounce into the waste bin 130 due to the elastic deformation of the sponge layer. As the drum 120 rotates, they are transferred to the first water tank A. The high flow rate of purified water in the first water tank A flushes these small particles away. Furthermore, the first water plate 113 interferes with the drum 120, allowing the waste to be scraped away there. The waste removed from the first water plate 113 flows into the sewage tank 140 along with the water flow.

[0082] When using the cleaning device of the present invention to clean wet garbage, the sponge layer of drum 120 absorbs the wet garbage. The wet garbage then flows along drum 120 to first water trough A, where purified water flushes drum 120 for the first time. Furthermore, first water pressure plate 113 squeezes the sponge layer of drum 120, releasing the wet garbage from the sponge layer and allowing it to flow into sewage tank 140. Drum 120 then continues rotating and enters second water trough B, where clean water inlet 115a sprays clean water, cleaning drum 120. Drum 120 then rotates to second water trough 114, where it is squeezed again, providing a second cleansing experience. The wet garbage then flows into sewage tank 140.

[0083] When using the cleaning device of the present invention to clean sticky waste, the sticky waste adheres to the sponge layer of drum 120 and partially penetrates the sponge layer. Drum 120 continues to rotate until it reaches the first water tank A. Purified water flushes the sticky waste, and the first water pressure plate 113 scrapes away sticky waste adhering to the surface of drum 120. The combined action of the water flow and the first water pressure plate 113 removes the sticky waste from the surface of drum 120, releasing any sticky waste that has penetrated the sponge layer and entering the sewage tank 140 along with the sewage. If any remaining sticky waste remains, fresh water sprayed from the fresh water inlet 115a creates a flushing force on the surface of drum 120. The second water pressure plate 114 further scrapes away any sticky waste adhering to the surface of drum 120. The combined action of the water flow and the second water pressure plate 114 releases any sticky waste that has penetrated the sponge layer and removes any sticky waste that adheres to the sponge layer, which then enters the sewage tank 140 along with the water flow.

[0084] The sewage entering the sewage tank 140 is filtered by the filter box and the filter net and returns to the first water tank A. The sewage is combined with the clean water sprayed from the clean water inlet 115 a to clean the drum 120 .

[0085] Because the cleaning device of the present invention has two water tanks and the sewage tank purifies the wastewater before recirculating it to the first water tank, it is very effective in cleaning hair and flocculent waste. During the cleaning process, hair and flocculent waste adhere to the sponge layer of drum 120. Drum 120 continues to rotate until it reaches first water tank A. Purified water filtered from sewage tank 140 flows into first water tank A. The flow rate of purified water can be set between 200 and 500 ml / min. This high flow rate can flush hair and flocculent waste from the surface of drum 120, and the first water pressure plate 113 can also scrape off any hair and flocculent waste adhering to the surface of drum 120. The combined effects of the high flow rate of sewage and the first water pressure plate 113 allow hair and flocculent waste to be removed from the surface of drum 120. The hair and flocculent waste then flow into sewage tank 140, which can then be removed for cleaning. The clean water inlet 115 a sprays clean water, and the second water pressing plate 114 presses the surface of the drum 120 . Under the combined action of the clean water and the second water pressing plate 114 , the drum 120 is cleaned, and the sewage enters the sewage tank 140 .

[0086] The sewage entering the sewage tank 140 is filtered by the filter box and the filter net and returns to the first water tank A.

[0087] 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.
