Description

Technical Field

[0001] The present disclosure belongs to the technical field of cleaning equipment, and in particular, relates to a cleaning device. Background Art

[0002] With the development of modern technology, there are many kinds of cleaning tools, including brooms, mops, floor wipes and vacuum cleaners, etc. For Chinese consumers, sweeping and mopping are necessary when cleaning the floor, and sweeping or mopping alone cannot achieve a thorough cleaning of the floor.

[0003] Existing integrated mop-and-sweep machines either need to be washed constantly or have a complicated structure and are very expensive, which makes ordinary consumers reluctant to buy them. In addition, during the mopping and sweeping process, garbage is particularly easy to clog the channels of existing integrated mop-and-sweep machines, which seriously affects the efficiency of mopping and sweeping, and requires users to frequently clean the sewage channels, which is quite troublesome. In addition, the drum, water tank, garbage box and other parts are particularly prone to mold and stink, and are difficult to clean.

[0004] In addition, most of the current sweepers with sewage tanks are equipped with sewage pumps. First, they require a high-speed rotating motor, which requires a lot of electricity. At the same time, they need to be waterproofed to prevent water from entering the motor and damaging the motor. At the same time, the weight of the machine will become heavier, making it difficult to operate and maintain. Moreover, particles may enter, increasing the risk of pump blockage.

[0105] The preferred embodiments of the present invention are described below in conjunction with 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.

[0106] The present invention relates to a cleaning tool, which can be used for cleaning the floor, in particular a small smooth and flat floor, such as a home and kitchen floor. The cleaning tool of the present invention is particularly suitable for cleaning mixed garbage containing dry garbage, wet garbage and viscous materials such as noodles, porridge, ketchup and the like.

[0107] The dry garbage mentioned in the present invention specifically refers to granular garbage, such as fruit peels, melon seed shells, rice grains, paper pieces, etc.

[0108] Wet garbage refers to liquid garbage, such as water, beverages, etc.

[0109] Sticky garbage (or sticky garbage) includes soup, stew, porridge, ketchup, chocolate sauce and other garbage with a certain viscosity.

[0110] Other garbage also includes dust, ground marks, etc., which are also cleaning objects of the present invention.

[0111] Figure 1 The figure shows a cleaning device according to the present invention, which comprises a handheld part 100 and a cleaning head 200 .

[0112] The handheld part 100 includes a connecting rod 110, a handle 120, and a clean water tank 130. The clean water tank 130 includes a clean water tank body 131 and a clean water tank body 132. The clean water tank body 131 is detachably mounted on the clean water tank body 132 (see FIG. Figure 2 ). The connecting rod 110 is used to connect the handle 120 and the clean water tank body 132. The connecting rod 110 can be an aluminum rod.

[0113] Figure 3 FIG. 2 is a cross-sectional view of a cleaning head 200 of a cleaning device of the present invention. Figure 3In the illustrated embodiment, the cleaning head 200 includes a housing 210, a drum 220, a garbage box 230, a sewage tank 240, and an ultraviolet lamp assembly 250. The housing 210 is provided with a shovel bar 211, which has an arc-shaped working surface, one end of which contacts the ground during operation, and the other end is connected to the garbage box 230. A gap (garbage channel) with a uniform distance is formed between the arc-shaped working surface and the outer circumference of the drum 220.

[0114] The roller 220 includes an inner layer of hard rubber and a sponge layer wrapped outside the hard rubber. The end of the hard rubber can be fixed to the housing 210 through a connecting piece such as a bearing. The roller driving mechanism drives the hard rubber to rotate around its axis through the roller transmission mechanism, driving the roller to rotate, so that the surface of the roller makes a circular motion.

[0115] The housing 210 is also provided with a water pressing plate 212 and a scraper assembly 213 . Figure 4 , Figure 5 The present invention shows a water pressing plate 212 and a scraper assembly 213. The water pressing plate 212 interferes with the drum 220. The water pressing plate 212 includes a straight section 212a and arc sections 212b arranged at both ends of the straight section. During the operation of the cleaning tool, the drum rotates continuously, and the water pressing plate 212 squeezes out the sewage in the drum. The straight section 212a and the arc sections 212b at both ends can maintain continuous squeezing of the drum. Such an arrangement can gather the sewage squeezed out from both ends of the drum and drain it into the primary water tank.

[0116] Figure 5 The scraper bar assembly 213 shown includes a friction portion 213a, a drainage portion 213b and a fixing portion 213c. Among them, the drainage portion 213b includes a water squeezing bar 213b-1 and a water receiving bar 213b-2. The friction portion 213a and the water squeezing bar 213b-1 interfere with the drum respectively (i.e., squeeze the drum). The water pressure plate 212, the water squeezing bar 213b-1, the water receiving bar 213b-2, and the drum 220 form a primary water tank, and the water receiving bar 213b-2 and the shell 210 form a secondary water tank. The friction portion 213a is in the shape of a "Y". The tip of the "Y" shape interferes with the drum of the drum cleaning tool, which helps to peel off the garbage adhering to the drum during the operation of the cleaning tool.

[0117] The shape of the drainage portion 213b is similar to a "Y" shape. The water receiving strip 213b-2 and the water squeezing strip 213b-1 are respectively two forks of the "Y" shape. The water squeezing strip 213b-1 interferes with the drum 220, and during the operation of the cleaning tool, cooperates with the arc-shaped working strip 111 of the water pressure plate 212 to squeeze out the water in the drum 220. As the drum 220 rotates, the water squeezed out of the drum 220 flows to the water storage space formed by the drainage portion 213b of the water pressure plate 212 and the drum 220. A set of drainage plates 213b-3 are arranged at both ends of the water squeezing strip 213b-1. Through the cooperation of the drainage plates 213b-3 and the arc-shaped segments 212b, the sewage squeezed out of the drum 220 is gathered and drained into the sink. This design can keep the portion of the drum 220 squeezed by the arc segment 212 b in an unsaturated state (ie, not fully absorbed with water), thereby preventing the water in the water tank from flowing out from both ends of the drum 220 .

[0118] According to an example embodiment of the present application, the material of the friction part 213a and the drainage part 213b can be soft glue. Soft glue is not only resistant to high temperatures, but also resistant to low temperatures, and can be used in a wide temperature range. Both chemical properties and physical and mechanical properties change very little with temperature. In addition, soft glue is not easily decomposed by ultraviolet light and ozone, so ultraviolet light disinfection of the cleaning tool will not affect its performance. Soft glue has good electrical insulation properties and can ensure the safety of cleaning tools under wet working conditions.

[0119] According to the example embodiment of the present application, the material of the fixing portion 213c can be hard glue. Hard glue has good thermal stability and will not cause decomposition at the molding temperature and a certain residence time. Hard glue has good fluidity and can smoothly fill a complex mold cavity under certain problem conditions. In addition, hard glue also has the characteristics of good shrinkage, easy demoulding, and good corrosion resistance. Therefore, hard glue is suitable for cleaning tools with complex shapes and harsh working environments.

[0120] The housing 210 and the clean water tank 130 may be connected via a hinge, or alternatively, may be connected via other means, which is not limited in the present invention.

[0121] The housing 210 is provided with a water tank inlet (not shown in the figure) and a water tank outlet (not shown in the figure). The water tank inlet is connected to the clean water tank 130, and the water tank outlet is connected to the sewage tank 240. The water tank inlet is preferably arranged above the primary water tank. The water pump of the present invention can adopt a water pump with adjustable water speed. When the clean water flow rate is relatively small, the primary water tank is in a saturated state, and a water flow with strong fluidity can be formed to wash the garbage and the garbage adhered to the surface of the drum 220 into the sewage tank 240. When the clean water flow rate is relatively large or there is water in the cleaned object (such as the ground), part of the sewage will enter the secondary water tank. The secondary water tank diverts part of the sewage, which can avoid leakage caused by excessive water volume and can quickly clean the sewage on the ground. The setting of the two-stage water tank of the present invention, on the one hand, expands the sewage channel, and the speed of the drum can be adjusted to be very fast, which can greatly improve the cleaning efficiency of the cleaning device; on the other hand, since some garbage (such as hair or small particles of dry garbage) will reach the water tank part with the drum, due to the setting of the water receiving strip 213b-2, the garbage cannot enter the secondary water tank and can only stay in the primary water tank. Even if the primary water tank is blocked by garbage, the secondary water tank can still remain unobstructed.

[0122] Optionally, in order not to use a sewage pump, the present invention sets the position of the primary water tank and the secondary water tank as high as possible. Optionally, the vertical distance between the primary water tank and the secondary water tank and the surface of the cleaned object (such as the ground) is greater than 25 mm, and at this time, the diameter of the drum is preferably greater than 40 mm.

[0123] Figure 3 In the illustrated embodiment, the cleaning head 200 is further provided with an ultraviolet lamp assembly 250. The ultraviolet lamp assembly 250 includes a lampshade 251 mounted on the housing 210 and an ultraviolet lamp 252 mounted in the lampshade 251. The ultraviolet lamp 252 can be mounted on the housing 210 via a lamp base 253. The ultraviolet lamp assembly 250 is located between the sewage tank 240 and the garbage box 230. The walls of the garbage box 230 and the sewage tank 240 close to the ultraviolet lamp assembly 250 are transparent. The ultraviolet light emitted by the ultraviolet lamp 252 can penetrate the transparent wall, thereby disinfecting and sterilizing the garbage box 230 and the sewage tank 240, and preventing the garbage box 230 and the sewage tank 240 from becoming moldy and smelly.

[0124] The garbage box 230 and the sewage tank 240 may be made detachable, that is, the garbage box 230 and the sewage tank 240 may be detachably mounted on the housing 210. In addition, the drum 220 may also be detachably arranged.

[0125] During the use of the cleaning device, the sewage tank 240 is in a sealed device. When the sewage enters the sewage tank 240, it is affected by the internal air resistance and flows slowly. In order to allow the sewage to flow smoothly into the sewage tank 240, a through hole may be provided on the top of the sewage tank 240, and the through hole may be one or more groups. After the through hole is provided, after the sewage enters the sewage tank 240, the air inside can be discharged from the sewage tank 240 through the through hole, so that the sewage can enter the sewage tank 240 more smoothly.

[0126] Since the cleaning device is in continuous reciprocating motion during use, the sewage stored in the sewage tank 240 may experience turbulent flow. The turbulent sewage inside may overflow from the through hole. In order to avoid such a situation, a retaining ring may be provided inside the sewage tank 240, usually around the through hole on the inner wall of the top plate. The retaining ring may be in the form of a circular ring or a cap with a vent. According to some embodiments of the present invention, the retaining ring may be a rubber ring.

[0127] The cleaning device of the present invention may further include an ozone generator. Figure 6 to Figure 8 In the illustrated embodiment, the ozone generator is installed at the lower end of the clean water tank body 132, and when the clean water tank body 131 is installed to the clean water tank body 132, the ozone generator 133 is connected to the clean water tank body 131. The clean water flowing out of the clean water tank 130 contains ozone, which can disinfect and sterilize the drum 220 to prevent the drum from getting moldy and smelly. In addition, since the water contains ozone, the floor can also be disinfected and sterilized after the floor is mopped with the roller 220.

[0128] like Figure 6 , Figure 7 As shown, an ozone generator 133, an air pump 134, a water pump 135, a pump shock absorber 136 and an interface kit 137 are installed at the lower end of the clean water tank body 132. Among them, the air pump 134 is connected to the ozone generator 133, the pump shock absorber 136 and the interface kit 137 respectively, the water pump 135 is connected to the pump shock absorber 136 and the interface kit 137 respectively, and the interface kit 137 is also connected to the clean water tank body 132. The ozone generator 133, the air pump 134, the water pump 135, the pump shock absorber 136 and the interface kit 137 are connected by a pipeline, and the pipeline is preferably a silicone tube. Figure 7 and Figure 8In the illustrated embodiment, the pipeline includes a first silicone tube 138a connecting the ozone generator 133 and the air pump 134, a second silicone tube 138b connecting the air pump 134 and the interface kit 137, and a third silicone tube 138c connecting the water pump 135 and the interface kit 137. The ozone generator 133 is provided with two ports, the first ozone port 133a is used to take in air to prepare ozone; the second ozone port 133b is used to connect the first silicone tube 138a to pass the prepared ozone into the clean water tank 130. The water pump 135 is also provided with two ports, the first water pump port 135a is connected to the fourth silicone tube 138d, and the clean water containing ozone flows from the first water pump port 135a through the fourth silicone tube 138d into the primary water tank and the secondary water tank.

[0129] like Figure 8 As shown, the bottom end of the clean water tank body 131 is provided with a sealing ring 131a, a bubble stone sleeve 131b, a filter cover 131c, a first return spring 131d, a second return spring 131e, a first one-way valve 131f, a second one-way valve 131g, and a connecting seat 131h. The first one-way valve 131f and the second one-way valve 131g can prevent water from flowing out of the clean water tank body 131 when the clean water tank body 131 is taken out from the clean water tank body 132. The bubble stone sleeve 131b is filled with bubble stone BS. The bubble stone has a porous structure, and when ozone is blown into the water, it is more conducive to the dissolution of ozone in the water. The filter cover 131c can prevent impurities in the water from clogging the pipeline and the pump body. The sealing ring 131a is respectively sleeved on the bubble stone sleeve 131b and the filter cover 131c. The first return spring 131d is connected to the bubble stone sleeve 131b and the first one-way valve 131f respectively, and the second return spring 131e is connected to the filter cover 131c and the second one-way valve 131g respectively. The first one-way valve 131f and the second one-way valve 131g are connected to the interface on the connecting seat 131h respectively. One end where the first one-way valve 131f and the second one-way valve 131g are connected to the connecting seat 131h is provided with a one-way valve sealing ring (not shown in the figure). When installed, the clean water tank body 131 is connected to the connecting seat 131h, and the sealing ring 131a, the bubble stone sleeve 131b, the filter cover 131c, the first return spring 131d, the second return spring 131e, the first one-way valve 131f, and the second one-way valve 131g are all accommodated in the accommodation space formed by the clean water tank body 131 and the connecting seat 131h. Figure 8 In the embodiment shown, screws 131i are used to fix the connection base 131h to the clean water tank body 131. Of course, other connection methods can also be used, which are not listed one by one here.

[0130] Figure 8The clean water tank 130 shown in the figure is provided with a visual window 131j on the clean water tank body 131, so as to observe the water level of the clean water in the clean water tank 130. Optionally, the visual window 131j can be arranged at the front and / or rear and / or side of the clean water tank body 131. The clean water tank body 131 is provided with a water inlet for convenient injection of clean water. The clean water tank 130 can be designed to be detachable for convenient cleaning. In addition, the clean water tank body 131 can also be provided with a small hole for equalizing air pressure to prevent the flow rate of the clean water from slowing down due to pressure.

[0131] Fig. 9 Another cleaning device of the present invention is shown, which is also provided with a base 300 (specifically as shown in FIG. Fig.10 The base 300 can be used alone. Fig.10 In the illustrated embodiment, the base 300 includes a charging port 310, a charging contact spring pin 320, a cleaning tank 330, and a storage tank 340. The charging port 310 is connected to the socket, and the charging contact spring pin 320 is used to charge the battery of the cleaning device. The battery is preferably installed in the handheld part 100, and can also be installed in the housing of the cleaning head 200. It can be a lithium battery or any other rechargeable battery, and the present invention does not make any limitation. When the cleaning head 200 is placed on the base 300, the base 300 charges the battery through the charging contact spring pin 320.

[0132] The cleaning tank 330 is provided with a groove portion, which cooperates with the outer surface of the drum 220 to accommodate the drum 220. When water is filled in the cleaning tank 330, the drum 220 is started to rotate, and the drum 220 can absorb the water in the cleaning tank 330 when rotating, so as to clean the drum 220.

[0133] The storage slot 340 is used to store items such as detergents and brushes for convenient storage.

[0134] Fig.11 The figure shows a longitudinal cross-sectional view of another cleaning device of the present invention. The handheld part 100 includes a connecting rod 110, a handle 120, a clean water tank 130, a first connecting part 140 and a second connecting part 150. The handle 120 is provided with a handle cover 121, an operation interface patch 122, a PCBA board 123 and a battery 124. The first connecting part 140 is used to connect the connecting rod 110 and the handle 120, and includes a handle terminal male 141, a rod elastic buckle 142 and a first rod terminal female 143.

[0135] The lower end of the connecting rod 110 is provided with a clean water tank body 132, and the second connecting part 150 is used to connect the connecting rod 110 and the clean water tank body 132. The clean water tank body 131 is detachably installed in the clean water tank body 132. The second connecting part 150 includes a second rod terminal female seat 151 and a water tank terminal male head 152. The clean water tank body 131 of this embodiment is Figure 7 A water tank removal button 131k is added to the clean water tank body to facilitate user operation.

[0136] In this embodiment, the clean water tank body 132 and the cleaning head 200 are connected via a hinge.

[0137] The cleaning head 200 of this embodiment is Figure 3 The cleaning head shown is partially different. The front end of the shell 210 of this embodiment is provided with a headlight 214, which is installed in the lampshade. When mopping dark places such as under the bed, the headlight 214 allows the user to see the specific conditions of the mopping place so that the cleaning can be carried out better. The front end of the shell 210 is also provided with an anti-collision strip 215 to prevent the shell 210 from being damaged during the mopping process. In addition, in order to facilitate the observation of the water situation in the sink, an observation window 216 is also provided above the primary sink and the secondary sink. The observation window 216 is made of a transparent material, such as glass or transparent plastic. For aesthetics, a decorative cover 217 is also provided on the side. A sewage removal button 241 is provided at the upper end of the sewage tank 240 for user convenience.

[0138] The base 300 of this embodiment and Fig.10 The bases shown are the same and will not be described in detail.

[0139] The handheld part 100 of this embodiment is provided with a PCBA board 123, in which a control component is arranged. The control component can be used to control the switch of the ozone generator and / or the ultraviolet lamp. The control component can also be used to control the operation of the entire cleaning device, control the rotation of the drum, control the operation of the water pump and the air pump, control the charging of the battery, etc., and when a roller is provided at the bottom of the cleaning head, control the forward and backward movement of the roller.

[0140] The roller includes a front wheel and a rear wheel. Optionally, the front wheel, the rear wheel and the lowest end of the shovel bar (the end in contact with the ground) are in the same horizontal plane and can touch the ground at the same time to support the cleaning device. The roller can be set to be lower than the contact surface of the shovel bar, so that the sponge layer of the roller rubs against the ground to achieve the purpose of cleaning the ground. However, it cannot touch the ground too much, otherwise the load on the roller is too large, and if it touches the ground too little, the purpose of cleaning will not be achieved.

[0141] Optionally, the control component is used to perform the following operations:

[0142] The control driving device drives the cleaning device to roll forward, drives the drum to rotate, and controls the clean water pump to pump clean water from the clean water tank to the primary water tank. In the process of rotation, the drum wraps the dry garbage on the surface of the cleaned object, absorbs the wet garbage on the surface of the cleaned object, and adheres to the sticky garbage on the surface of the cleaned object, so that the dry garbage, wet garbage and sticky garbage are removed from the surface of the cleaned object. When the dry garbage rotates to the top of the garbage box with the drum, the drum surface is deformed due to the loss of the pressure of the shovel bar, and the dry garbage is released, and the dry garbage enters the garbage box. Part of the dry garbage and sticky garbage is scraped off by the friction part of the scraper assembly and enters the garbage box. The wet garbage and the unremoved dry garbage and sticky garbage rotate with the drum to the first water tank. The clean water flows in the primary water tank, thereby flushing the wet garbage absorbed by the drum, the sticky garbage adhered to the drum surface, and the dry garbage not released from the drum surface into the sewage tank.

[0143] When a base is provided, the cleaning device of the present invention can have two self-cleaning modes. One is to increase the water outlet speed of the water pump and also increase the rotation speed of the drum. At this time, both the primary water tank and the secondary water tank are filled with water, which is equivalent to the drum being rinsed in water, and the drum is cleaned by cooperating with the extrusion plate. The second is to use the cleaning tank of the base for cleaning. The cleaning tank is filled with water, and the drum rotates to suck up the water in the water tank. Under the joint action of the water flow and the extrusion plate, the drum is cleaned.

[0144] Optionally, the control component is used to perform the following operations:

[0145] The control driving device drives the drum to rotate. The drum absorbs clean water in the cleaning tank, and the water pressure plate squeezes the drum that absorbs the clean water, thereby cleaning the drum, and the sewage flows into the sewage tank through the primary water tank and the secondary water tank.

[0146] Optionally, the control component is used to perform the following operations:

[0147] Adjust the rotation speed of the drum. The faster the drum rotates, the faster it cleans, but it cannot be too fast and needs to be adjusted according to the type and amount of garbage being cleaned. Optionally, the control component is used to perform the following operations:

[0148] The driving device is controlled to drive the drum to rotate; and the clean water pump is controlled to pump clean water from the clean water tank to the primary water tank.

[0149] Among them, clean water flows in the primary water tank to rinse the drum, and the water pressure plate squeezes the drum that absorbs the clean water to further clean the drum, and the sewage flows into the sewage tank through the primary water tank and the secondary water tank.

[0150] Optionally, the control component is used to perform the following operations:

[0151] The speed of pumping clean water from the clean water tank is adjusted according to the degree of dirtiness of the surface of the object to be cleaned and the type of garbage. When the speed is the first suction speed, the clean water flows in the primary water tank, thereby flushing the garbage adhering to the surface of the drum into the sewage tank. When the speed is the second suction speed, the clean water flows in the primary water tank, thereby flushing the garbage adhering to the surface of the drum into the sewage tank, and part of the sewage enters the secondary water tank and flows into the sewage tank. The second suction speed is greater than the first suction speed.

[0152] When the cleaning device of the present invention is used to clean dry garbage on the ground, when the drum 220 rolls over the ground, the dry garbage particles on the ground compress and deform the sponge layer of the drum 220, and the sponge layer wraps the dry garbage particles through deformation, so that the dry garbage particles are separated from the ground and rotate with the drum 220. When the drum 220 reaches the position of the shovel bar 211, the dry garbage particles leave the ground, are squeezed by the shovel bar 211, and continue to rotate with the drum 220. When the drum 220 passes the shovel bar 211 and reaches the entrance of the garbage box 230, the sponge layer recovers and deforms due to the loss of the pressure of the shovel bar 211, and the dry garbage particles wrapped by it are released, and the garbage enters the garbage box 230 under the action of its own weight and elastic force.

[0153] Some small particles of dry garbage may not be able to bounce into the garbage box 230 through the elastic deformation of the sponge layer, and they can also be scraped off by the friction part 213a of the scraper assembly 213 and fall into the garbage box 230. If they have not been removed from the drum 220, they will be transferred to the primary water tank as the drum 220 rotates. Water flows in the primary water tank, forming a flushing force, and can also remove garbage from the surface of the drum 220. In addition, the water pressure plate 212 also interferes with the drum 220, and garbage can also be scraped here. The garbage removed from the primary water tank and the water pressure plate 212 flows into the sewage tank 240 with the water flow. Since the scraper assembly 213 is provided with a water receiving strip 213b-2, the garbage cannot reach the secondary water tank and will not block the water tank. Through the above arrangement, the dry garbage can be removed from the ground very cleanly without blocking the device.

[0154] When the cleaning device of the present invention is used to clean wet garbage, the sponge layer of the drum 220 absorbs the wet garbage. The wet garbage moves with the drum 220 to the primary water tank, water flows in the primary water tank, and the water pressing plate 212 squeezes the sponge layer of the drum 220, and the wet garbage is released from the sponge layer and enters the sewage tank 240 along with the water flow.

[0155] When the cleaning device of the present invention is used to clean sticky garbage, the sticky garbage adheres to the sponge layer of the drum 220 and partially penetrates into the sponge layer of the drum 220. The drum 220 continues to rotate, and the friction portion 213a of the scraper assembly 213 can hang down a part of the sticky garbage adhered to the surface of the drum 220, and the scraped garbage enters the garbage box 230 by its own weight. The sticky garbage that cannot be scraped off reaches the primary water tank. The water flows in the primary water tank and can wash the sticky garbage adhered to the surface of the drum 220. In addition, the water pressure plate 212 can also scrape off the sticky garbage adhered to the surface of the drum 220. Under the combined action of the water flow and the water pressure plate 212, the sticky garbage that penetrates into the sponge layer is released, and the sticky garbage adhered to the sponge layer is also removed and enters the sewage tank 240 with the water flow.

[0156] In other embodiments of the present invention, a toothed stripping structure 218 may be provided at the connection between the garbage box 230 and the shovel bar 211 (see Fig.12 ), the toothed stripping structure also interferes with the roller 220. The toothed stripping structure 218 can be made of soft rubber, or a flexible sheet can be rolled into a strip. In this way, when the garbage comes out of the garbage channel, the toothed stripping structure can scrape part of the garbage off the surface of the roller 220, greatly improving the garbage cleaning capability.

[0157] In the present invention, clean water is poured into the clean water tank, and the clean water flows into the primary water tank from the clean water tank. After cleaning the drum, the clean water becomes sewage, and flows into the sewage tank from the primary water tank and the secondary water tank. Finally, the sewage tank is taken out and the sewage is poured out. The whole process is very convenient.

[0158] Alternatively, if Fig.13 As shown, an inclined sewage channel 219 is provided on the side of the housing 210, and the sewage in the primary water tank and the secondary water tank flows into the sewage tank 240 from the sewage channel 219 by self-weight. Optionally, the sewage channel forms an angle of 2° to 5° with the horizontal plane. The sewage channel 219 may also be provided with a wall cover 219a detachably mounted on the side wall of the sewage channel 219. Fig.12 The direction of the arrow is the direction of water flow.

[0159] Optionally, a control panel (such as Fig.14As shown), there are four control modes on it, namely, "Standard" button, "Wetland" button, "Dry Mop" button and "Self-cleaning" button. In the "Standard" button, the water outlet speed of clean water can be 40-60mL / min. When there is no wet garbage on the ground, use the "Standard" button. In the "Wetland" button, the water outlet speed of clean water can be 60-80mL / min. When there is wet garbage on the ground or there is a lot of sticky garbage, use the "Wetland" button. The "Dry Mop" button does not spray water and is only used to clean dry garbage that is easier to remove. In the "Self-cleaning" button, the water outlet speed of clean water can be 200-300mL / min. In this mode, the drum is cleaned. The above water speeds are only used as examples and can be set according to actual conditions. Optionally, a "Sterilization" button can also be set on the control panel to control the turning on and off of the ozone generator and / or ultraviolet lamp.

[0160] 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.

[0161] Obviously, the above embodiments are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
