Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a solid garbage box, a sewage tank and cleaning equipment. Background Art

[0002] With the development of smart homes, various smart cleaning devices have been widely used in households and have become little helpers for household cleaning. Common smart cleaning devices include cleaning robots, floor scrubbers, vacuum cleaners, etc. Among them, the cleaning equipment uses negative pressure to suck the solid-liquid mixture on the ground into the sewage tank. The sewage tank is divided into a solid waste bin and a liquid storage bin by a filtering device in the sewage tank. The solid waste is filtered out of the solid-liquid mixture sucked into the sewage tank by the filtering device in the sewage tank, and the filtered liquid is stored in the liquid storage bin of the sewage tank.

[0003] However, existing cleaning equipment all uses a filter device for filtering. When the solid waste filtered by the filter device reaches a certain amount, the device must be stopped to clean the waste filtered by the filter device and clean the filter device. The cleaning equipment cannot be quickly restored to use. When used in large-area cleaning task scenarios, users need to clean the waste and clean the filter device multiple times during the cleaning process, which consumes a lot of time and affects the user's ability to quickly complete the cleaning task.

[0055] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0056] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0057] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0058] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0059] The utility model provides a solid waste box, which is mainly used in a sewage tank of a cleaning device to separate the solid-liquid mixture (i.e., a mixture of solid waste and sewage) entering the sewage tank, thereby collecting the separated solid waste. The cleaning device may be a floor scrubber, a cleaning robot, or other equipment for cleaning the surface of an object.

[0060] Reference Figure 1In this embodiment, the solid waste box includes a box body 10, a first filter device 20 and a second filter device 30. The box body 10 is provided with a sewage inlet 11 and a sewage outlet 12. When the solid waste box is used in a sewage tank, the solid-liquid mixture enters the box body 10 from the sewage inlet 11 of the box body 10. After being filtered by the filter device in the box body 10, the solid waste remains in the box body 10, and the sewage flows out of the box body 10 from the sewage outlet 12 (flowing into the liquid storage tank of the sewage tank). Among them, the first filter device 20 is arranged in the box body 10, and the first filter device 20 is located between the sewage inlet 11 and the sewage outlet 12; the second filter device 30 is detachably arranged in the box body 10, and the second filter device 30 is located between the sewage inlet 11 and the first filter device 20; that is, the positions of the sewage inlet 11, the second filter device 30, the first filter device 20, and the sewage outlet 12 are distributed in sequence.

[0061] Since the second filter device 30 and the box body 10 are detachably assembled, the solid waste box of this embodiment has two usage modes, the first mode is to set the second filter device 30 in the box body 10 for use, and the second mode is to remove the second filter device 30 from the box body 10 and take it out for use. When the second filter device 30 is set in the box body 10, the dirt (solid-liquid mixture) entering from the sewage inlet 11 is first filtered by the second filter device 30, and then flows to the sewage outlet 12 through the first filter device 20; when the solid waste box takes the second filter device 30 out of the box body 10, the dirt entering from the sewage inlet 11 is directly filtered by the first filter device 20, and the filtered sewage flows to the sewage outlet 12 to flow out of the box body 10. Since the solid waste box of this embodiment has two usage modes, users have more choices of usage modes, which is more flexible in actual use.

[0062] For example, when the second filter device 30 is full of solid waste during operation, the user can choose to remove the second filter device 30 first, let the cleaning device continue to work, and then clean the first filter device 20 and the removed second filter device 30 together after the cleaning task is completed. For another example, the second filter device 30 can be a low-cost disposable filter device (such as a paper filter device with good water resistance). When the second filter device 30 is full of solid waste, the second filter device 30 can be directly removed and thrown away, and replaced with a new second filter device 30 to resume use immediately.

[0063] The technical solution of the solid waste box of this embodiment is that a first filter device 20 and a second filter device 30 are installed in the box body 10 of the solid waste box, and the second filter device 30 and the first filter device 20 are sequentially arranged between the sewage inlet 11 and the sewage outlet 12. The sewage entering the sewage inlet 11 is first filtered by the second filter device 30, and then flows to the sewage outlet 12 through the first filter device 20, that is, the solid waste in the box body 10 is accumulated in the second filter device 30. The cleaning device using the solid waste box of the present embodiment can be used. During use, when the solid waste in the box body 10 of the solid waste box reaches a certain amount (such as the second filter device 30 is full of solid waste), the user can directly take out the second filter device 30 to take out the solid waste in the box body 10, and the solid waste box can continue to filter normally through the first filter device 20 in the box body 10, so that the cleaning device can be immediately restored to normal use; or, the second filter device 30 can be a disposable filter device, so that when the second filter device 30 is full of solid waste, the second filter device 30 can be directly taken out and thrown away, and replaced with a new second filter device 30, so that the cleaning device can be immediately restored to normal use; in this way, the solution of the solid waste box of the present embodiment can effectively reduce the time for the user to clean the filter device during the cleaning process, so that the cleaning device can resume normal operation faster, and the user can use the cleaning device to complete the cleaning task faster.

[0064] Combined with reference Figure 6 In some embodiments, the box body 10 is further provided with an opening K for the filter device to dump garbage or take in and out the filter device. In the figure, an entire side of the box body 10 is opened to form the opening K as an example. In this embodiment, the opening K is provided to facilitate the user to clean solid garbage and take in and out the second filter device 30. For example, when the second filter device 30 or the first filter device 20 is full of solid garbage, the user can dump the garbage on the second filter device 30 or the first filter device 20 through the opening K of the box body 10 after taking out the solid garbage box; or, when the second filter device 30 is full of solid garbage, the second filter device 30 is taken out from the box body 10 through the opening K to clean the garbage in the second filter device 30, and after cleaning, the second filter device 30 is reinstalled into the box body 10 from the opening K, or a new second filter device 30 is replaced into the box body 10 through the opening K.

[0065] In some embodiments, the first filter device 20 includes a plurality of first filter holes, the second filter device 30 includes a plurality of second filter holes, and at least some of the plurality of first filter holes and the plurality of second filter holes are aligned, thereby ensuring that the sewage can smoothly pass through the second filter device 30 and the first filter device 20 in sequence and flow out of the box body 10 through the sewage outlet 12.

[0066] In some embodiments, the second filter device 30 is made of a different material from the first filter device 20; for example, the second filter device 30 and the first filter device 20 can be made of different materials among the following materials, respectively, and the various materials may include plastic, water-resistant paper, polymer materials, alloys, etc.; among them, the first filter device 20 that needs to be recycled can be made of durable materials (such as plastic, polymer materials, alloys, etc.), and if the second filter device 30 is designed as a disposable filter device, low-cost paper materials or other low-cost materials can be used.

[0067] In some embodiments, the second filter device 30 is installed differently from the first filter device 20; for example, the first filter device 20 is connected to the box body 10 by means of hinge or clamping, and the second filter device 30 is clamped in the box body 10 by interference fit with the inner wall of the box body 10, or the second filter device 30 is clamped with the first filter device 20. Among them, the second filter device 30 can be installed in a quick disassembly and assembly manner, which makes it more convenient for users to take, place or replace the second filter device 30.

[0068] In some embodiments, the second filter device 30 is disposed above the first filter device 20; since water flows downward, the second filter device 30 and the first filter device 20 are disposed in an up-and-down manner, which can facilitate the sewage to pass through the second filter device 30 and the first filter device 20 in sequence and quickly, and the filtering efficiency is higher. Of course, in some other embodiments, the second filter device 30 and the first filter device 20 can also be disposed side by side or in other distribution methods.

[0069] In some embodiments, the second filter device 30 is spaced apart from the first filter device 20 , so that even if the water holes of the second filter device 30 are not aligned with the water holes of the first filter device 20 , it will not affect the normal filtering process of the two filter devices.

[0070] In some embodiments, the first filter device 20 is made of plastic, which has the advantages of being durable, lightweight, low cost and easy to shape. Therefore, using a first filter device 20 made of plastic can make the production and processing of the first filter device easier, more durable, and can make the overall weight of the solid waste box smaller.

[0071] In some embodiments, the second filter device 30 is made of waterproof hard cardboard. The waterproof hard cardboard is low in cost, has good load-bearing capacity, and has good structural strength. Therefore, the second filter device 30 made of waterproof hard cardboard is very suitable as a disposable filter device with low consumption cost. In addition, since the hard cardboard is recyclable and degradable, it is more environmentally friendly.

[0072] In some embodiments, the second filter device 30 has at least partially different functions from the first filter device 20. For example, the first filter device 20 may be a filter device with maximized capacity, a filter device that can gather solid waste, or a filter device that prevents waste from entering the air suction channel, and the second filter device 30 may be a disposable filter device, a filter device that can gather solid waste, or a filter device that prevents waste from entering the air suction channel. In this embodiment, the second filter device 30 and the first filter device 20 are designed to have different functions, so that users can choose whether to use the second filter device 30 according to actual needs.

[0073] Taking the first filter device 20 as a filter device with maximized capacity, the second filter device 30 as a disposable filter device, a filter device that can gather solid waste, and a filter device that prevents waste from entering the air suction channel as an example, the following lists some possible usage scenarios of a cleaning device (taking a floor scrubber) using a solid waste box of this embodiment:

[0074] 1. When the user only needs to clean a small area, the user can choose to assemble the second filter device 30 with the function of gathering solid waste into the box body 10 for use, so as to prevent the waste in the solid waste box from spreading everywhere, making it more convenient for the user to clean the box body 10 and the filter device after the cleaning task is completed;

[0075] 2. When the user needs to clean a large area, the user can choose to remove the second filter device 30 and let the first filter device 20 with the largest capacity perform filtering. This can make the solid waste box collect a larger amount of solid waste, avoiding the situation where the floor scrubber is full after a short time of use due to the small capacity of the filter device, thereby reducing the number of times the user pauses to clean the filter device during the entire cleaning process, allowing the user to complete the cleaning task faster and improve cleaning efficiency;

[0076] 3. When the user needs to clean an area where there is easily floating garbage, the user can select a second filter device 30 that can prevent garbage from entering the air suction channel and assemble it into the box body 10 for use, so as to prevent easily floating garbage in the solid garbage box from being sucked into the air suction channel and prevent the negative pressure device (such as the fan) from being damaged by the garbage;

[0077] 4. If the user does not want to clean the solid waste box or the filter device after using the floor scrubber (for example, in the cold winter), the user can choose to assemble the disposable second filter device 30 into the box body 10 for use. In this way, after using the floor scrubber, the user only needs to take out the disposable filter device containing solid waste in the box body 10 and throw it away directly, which can save the user the trouble of cleaning the solid waste box, making it more convenient for the user to use; and, only a new disposable filter device or other filter device needs to be replaced for the user to continue using next time.

[0078] Reference Figure 1 In some embodiments, the first filter device 20 is connected to the box body 10 via a hinge structure 13, so that the first filter device 20 can rotate relative to the box body 10. The first filter device 20 can be hinged to the box body 10 at a position close to the opening K of the box body 10. In this way, when the solid waste box only uses the first filter device 20 for filtering, the user can clean the solid waste collected on the first filter device 20 by flipping the first filter device 20 toward the opening K of the box body 10, thereby dumping the solid waste collected on the first filter device 20. In this way, the user does not need to remove the first filter device 20 for cleaning, and the operation is more convenient.

[0079] Of course, in other embodiments, the first filter device 20 or the second filter device 30 may be connected to the box body 10 via a snap-fit ​​structure; or, the first filter device 20 or the second filter device 30 may be interference fit with the inner wall of the box body 10 .

[0080] Reference Figure 1In some embodiments, the first filter device 20 includes a first filter plate 21, the first filter plate 21 is provided with a water hole, the first filter plate 21 is arranged at the bottom of the box body 10, and a first spacing space S1 is formed between the first filter plate 21 and the bottom wall 14 of the box body 10, and the sewage outlet 12 is connected to the first spacing space S1. The first spacing space S1 flows out between the first filter plate 21 and the bottom wall 14 of the box body 10, so that the sewage entering the solid waste box can smoothly pass through the first filter plate 21, and then flow out of the box body 10 from the sewage outlet 12 (flow into the liquid storage tank of the sewage tank). In the present embodiment, the first filter device 20 is designed as a first filter plate 21 of a plate-like structure, and the first filter plate 21 is located at the bottom of the box body 10 when assembled in the box body 10. When the solid waste box only uses the first filter device 20 for filtering, all the solid waste is filtered and retained on the first filter plate 21. The space between the first filter plate 21 and the inner wall of the box body 10 and located above the first filter plate 21 and the sewage inlet 11 is all solid waste storage space. Therefore, the first filter device 20 of the present embodiment can maximize the solid waste capacity of the solid waste box, so that the user can have a longer period of cleaning the solid waste in the solid waste box, which effectively improves the situation where the user needs to clean the solid waste box frequently.

[0081] Reference Figure 5 In some embodiments, the first filter device 20 and / or the second filter device 30 is provided with at least one air permeable baffle 22 ( Figure 5 In the example, the first filter device 20 is provided with two air-permeable baffles 22, and the air-permeable baffles 22 are provided to block the air suction port 15 facing the box body 10. In this embodiment, the air-permeable baffles 22 are further provided to block the air suction port 15, thereby effectively preventing the solid waste in the box body 10 from being sucked into the air suction port 15 and causing damage to the negative pressure device. Among them, the air-permeable baffles 22 can be grille plates, mesh plates, etc. In this embodiment, Figure 5 The first filter device 20 shown in the figure is a solution in which a breathable baffle plate 22 is added to the first filter plate 21, so that the first filter device 20 can prevent solid waste from entering the air suction channel. The breathable baffle plate 22 and the filter plate can be connected by a vertically extending connecting plate or connecting strip; of course, the first filter device 20 can be used for structures of other shapes. Figure 5 The air baffle 22 of the structure shape shown, or other shapes of air baffle 22 are used. It should be noted that the air baffle 22 of this embodiment can also be set on the second filter device 30, and the setting method can be the same or similar to the setting method of the air baffle 22 in the first filter device 20.

[0082] Reference Figure 1 and Figure 2In some embodiments, the second filter device 30 includes a filter box arranged above the first filter device 20, the top side of the filter box is open, the bottom and / or side wall of the filter box are provided with water holes, and the water holes of the filter box are at least partially aligned with the water holes of the first filter device 20.

[0083] In this embodiment, the second filter device 30 is designed as a filter box with a box-like structure. When the solid waste box is equipped with the second filter device 30 for in-and-out filtration, the solid-liquid mixture entering from the sewage inlet 11 falls into the filter box. After the filtering action of the filter box, all the solid waste remains in the filter box, and the sewage flows out from the water holes at the bottom and / or side wall of the filter box. The sewage flows out through the first filter device 20 and finally flows out of the box body 10 from the sewage outlet 12. The second filter device 30 adopts the filter box solution, so that after filtration, all the solid waste is collected in the filter box and will not remain on the inner wall of the box body 10. In this way, after using the cleaning device, the user only needs to clean the filter box, which reduces the trouble of cleaning the inner wall of the box body 1010. Furthermore, the second filter device 30 can be a disposable filter box made of a low-cost material (such as a water-resistant paper material), so that when the user cleans the solid waste in the solid waste box, the user can directly take out the filter box and throw it away, and replace it with a new filter box for continued use, so that the user does not need to clean the filter box or the box body 10, which is more convenient to use. At the same time, since the side wall of the filter box extends upward from the bottom of the filter box, the filtered solid waste can be stably retained in the filter box, and due to the presence of the opening K, the design of the filter box can prevent the solid waste from falling from the opening K when the user takes the solid waste box out of the sewage tank.

[0084] In some embodiments, when the filter box is installed in the box body 10, the periphery of the filter box opening fits against the inner wall of the box body 10 to prevent solid waste from falling into the gap between the filter box and the inner wall of the box body 10, causing cleaning trouble.

[0085] In some embodiments, a second spacing space is formed between the bottom of the filter box and the first filter device 20. By designing the second spacing space, there is a reserved space between the bottom of the filter box and the first filter device 20 for sewage to flow out smoothly from the water hole at the bottom of the filter box, and the situation that the bottom of the filter box and the first filter device 20 are too close to each other and are easily blocked by solid waste is avoided, thereby ensuring the stable filtering work of the solid waste box.

[0086] Combination Figure 1 And refer to Figure 2 In some embodiments, the filter box is connected to the first filter device 20 through a positioning structure, the positioning structure includes a plurality of positioning posts 31 and a plurality of positioning holes, each positioning post 31 is respectively inserted into each positioning hole; one of the positioning posts 31 and the positioning holes is arranged on the outer bottom surface of the filter box, and the other one is arranged on the side of the first filter device 20 opposite to the outer bottom surface of the filter box, Figure 2 In the example, the positioning column 31 is set on the outer bottom surface of the filter box, and the corresponding positioning hole is set on the side of the first filter device 20 that is opposite to the outer bottom surface of the filter box. In this embodiment, the filter box is positioned and placed on the first filter device 20 by the positioning column 31. The assembly is simple and the disassembly is convenient, which is convenient for users to disassemble or replace the filter box. Specifically, the figure shows a structural schematic diagram of the first filter plate 21 and the filter box positioning cooperation. In the scheme shown in the figure, the water holes on the bottom of the filter box and the water holes on the first filter plate 21 are aligned to ensure that the sewage can pass smoothly. Of course, when the first filter device 20 is other structural schemes, the second filter device 30 and the first filter device 20 can also be assembled by the positioning column 31 cooperating with the positioning hole.

[0087] Reference Figure 3 and Figure 4 In some embodiments, the second filter device 30 includes a filter frame 221 with a water hole, and the filter frame 221 divides the internal space of the box body 10 into a first chamber V1 and a second chamber V2. The sewage inlet 11 is connected to the first chamber V1, and the sewage outlet 12 and the air suction port 15 of the box body 10 are both connected to the second chamber V2. It should be noted that Figure 4 It is only for illustrating the enclosing cooperation mode between the filter frame 221 and the inner wall structure of the box body 10. Figure 4 The schematic diagram of the first filter device 20 is omitted in the figure. In the actual scheme, the bottom of the filter frame 221 and the bottom wall 14 of the box body 10 are also provided with the first filter device 20. The solid-liquid mixture entering from the sewage inlet 11 first reaches the first cavity V1, and then is filtered by the filter frame 221. The solid waste in the solid-liquid mixture remains in the first cavity V1 (i.e., remains in the filter frame 221), and the sewage in the solid-liquid mixture flows into the second cavity V2 through the filter frame 221, and then flows into the first filter device 20 below the filter frame 221, and finally flows out of the box body 10 from the sewage outlet 12. In this embodiment, the second filter device 30 is a filter frame 221 with a frame-like structure, and the filter frame 221 divides the internal space of the box body 10 into the first cavity V1 and the second cavity V2, so that after being filtered by the filter frame 221, all the solid waste is concentrated in the first cavity V1, so that the solid waste in the box body 10 is more gathered, and the solid waste is prevented from spreading everywhere, so that it is more convenient for the user to clean the solid waste box after using the cleaning device.

[0088] In some embodiments, the filter frame 221 includes a bottom plate 2211 and two side plates 2212 arranged opposite to each other at intervals, and water holes are provided on the bottom plate 2211 and / or the side plates 2212. That is, the filter frame 221 of this embodiment is a semi-frame structure surrounded by the two side plates 2212 and the bottom plate 2211. When the filter frame 221 is filtering, the sewage flows out from the water holes on the bottom plate 2211 and / or the water holes on the side plates 2212 to the second chamber V2. It is preferred that the bottom plate 2211 and the side plates 2212 of the filter frame 221 are both provided with water holes, so that the sewage passing speed of the filter frame 221 can be guaranteed, and at the same time, when the water holes of the bottom plate 2211 or the side plates 2212 are blocked by solid garbage, the situation that the sewage cannot flow out can be avoided, thereby ensuring the reliability of the filtering work of the filter frame 221.

[0089] In some embodiments, the bottom plate 2211 of the filter frame 221 is provided with a water hole, and the bottom plate 2211 of the filter frame 221 is spaced apart from the bottom of the first filter device 20. By placing the bottom plate 2211 of the filter frame 221 close to the bottom of the first filter device 20, the space of the first cavity V1 can be made larger, thereby increasing the capacity of the solid waste that can be collected, and the bottom plate 2211 of the filter frame 221 is spaced apart from the bottom of the first filter device 20 to ensure the smoothness of the sewage passing through the water hole of the bottom plate 2211, so that the sewage can flow out of the first cavity V1 faster.

[0090] In some embodiments, the inner wall of the box body 10 is provided with a semi-frame structure 16, the sewage inlet 11 is located on the inner side of the semi-frame structure 16, the air outlet 15 of the box body 10 is located on the outer side of the semi-frame structure 16, and the filter frame 221 and the semi-frame structure 16 enclose the first cavity V1. In this embodiment, the semi-frame structure 16 is arranged in the box body 10 to cooperate with the filter frame 221 to enclose the first cavity V1, so that the height of the filter frame 221 can be reduced, and the cost of the filter frame 221 can be effectively reduced; and the semi-frame structure 16 encloses the sewage inlet 11 on its inner side, and places the air outlet 15 of the box body 10 on its outer side, so as to block the sewage splashing generated when the sewage inlet 11 enters the solid-liquid mixture, prevent the sewage from splashing to the air outlet 15 and entering the negative pressure device, and ensure the safe operation of the negative pressure device.

[0091] In some embodiments, the second filter device 30 includes a second filter plate disposed above the first filter device 20, the second filter plate is spaced from the first filter device 20, or the water holes of the second filter plate are at least partially aligned with the water holes of the first filter device 20, so as to ensure that the sewage can smoothly pass through the second filter plate and the first filter device 20 in turn. The structure of the second filter plate is similar to that of the first filter plate 21, and the structure of the first filter plate 21 in the above embodiment can be referred to, but the material of the second filter plate can be different from that of the first filter plate 21. For example, when the second filter plate is used as a disposable component, a low-cost water-resistant paper material can be used. In this embodiment, the second filter device 30 reduces the cost of the second filter device 30 by adopting the second filter plate, and is convenient for disassembly and assembly, and can increase the capacity of solid waste that can be collected on the second filter device 30.

[0092] In conjunction with the accompanying drawings of the aforementioned embodiments, Figure 7 and Figure 8 The utility model further proposes a sewage tank, which includes a box body 100 and the above-mentioned solid waste box 200. The solid waste box 200 is installed on the top of the box body 100. The box body 100 has a liquid storage tank 101 located below the solid waste box 200. The liquid storage tank 101 is connected to the sewage outlet 12 of the solid waste box 200. The sewage filtered by the solid waste box 200 flows out from the sewage outlet 12 to the liquid storage tank 101 for storage. The specific structure of the solid waste box 200 refers to the above-mentioned embodiment. Since the sewage tank adopts all the technical solutions of all the embodiments of the solid waste box 200, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0093] The utility model also proposes a sewage tank, comprising a tank body, a first filter device and a second filter device, the tank body comprising a sewage inlet; the first filter device is arranged in the tank body, and divides the tank body into a solid waste bin and a liquid storage bin; the second filter device is detachably arranged in the tank body, and is located between the sewage inlet and the first filter device; that is, the positions of the sewage inlet, the second filter device, the first filter device, and the liquid storage bin are distributed in sequence. Since the second filter device and the tank body are detachably assembled, the sewage tank of this embodiment has two usage modes, the first mode is that the second filter device is arranged in the tank body for use, and the second mode is that the second filter device is removed from the tank body and taken out for use. When the second filter device is arranged in the tank body, the dirt (solid-liquid mixture) entering from the sewage inlet is first filtered by the second filter device, and then flows to the liquid storage bin through the first filter device; when the second filter device is taken out of the tank body, the dirt entering from the sewage inlet is directly filtered by the first filter device, and the filtered sewage directly flows into the liquid storage bin. Since the sewage tank of this embodiment has two usage modes, the user has more usage options and is more flexible in actual use.

[0094] For example, when the second filter device is full of solid waste during operation, the user can choose to remove the second filter device first, let the cleaning device continue to work, and then clean the first filter device and the removed second filter device together after the cleaning task is completed. For another example, the second filter device can be a low-cost disposable filter device (such as a paper filter device with good water resistance). When the second filter device is full of solid waste, the second filter device can be directly removed and thrown away, and replaced with a new second filter device to resume use immediately.

[0095] The technical solution of the sewage tank of this embodiment is that a first filter device and a second filter device are installed in the box body of the sewage tank, and the second filter device and the first filter device are sequentially arranged between the sewage inlet and the liquid storage tank. The sewage entering the sewage inlet is first filtered by the second filter device, and then flows into the liquid storage tank through the first filter device, that is, the solid waste in the box body is accumulated in the second filter device. In the cleaning device using the sewage tank of this embodiment, when the solid waste in the box body of the sewage tank reaches a certain amount (such as the second filter device is full of solid waste), the user can directly take out the second filter device to take out the solid waste in the box body, and the sewage tank can continue to filter normally through the first filter device in the box body, so that the cleaning device can be immediately restored to normal use; or, the second filter device can be a disposable filter device, so that when the second filter device is full of solid waste, the second filter device can be directly taken out and thrown away, and replaced with a new second filter device, so that the cleaning device can be immediately restored to normal use; in this way, the solution of the sewage tank of this embodiment can effectively reduce the time for users to clean the filter device during the cleaning process, so that the cleaning device can resume normal work faster, and the user can use the cleaning device to complete the cleaning task faster.

[0096] In some embodiments, the first filter device includes a plurality of first filter holes, the second filter device includes a plurality of second filter holes, and at least some of the plurality of first filter holes and the plurality of second filter holes are aligned, thereby ensuring that the sewage can smoothly pass through the second filter device and the first filter device in sequence and flow out of the box through the sewage outlet.

[0097] In some embodiments, the second filter device is made of a different material from the first filter device; for example, the second filter device and the first filter device can be made of different materials among the following materials, respectively, and the various materials may include plastic, water-resistant paper, polymer materials, alloys, etc.; among them, the first filter device that needs to be recycled can use a durable material (such as plastic, polymer materials, alloys, etc.), and if the second filter device is designed as a disposable filter device, low-cost paper material or other low-cost materials can be used.

[0098] In some embodiments, the second filter device is installed differently from the first filter device; for example, the first filter device is connected to the housing by hinges or snap connections, and the second filter device is snapped into the housing by interference fit with the inner wall of the housing, or the second filter device is snapped into the first filter device. The second filter device can be installed in a quick-disassembly manner, which makes it more convenient for users to take out or replace the second filter device.

[0099] In some embodiments, the second filter device is arranged above the first filter device; because water flows to lower places, therefore, by distributing the second filter device and the first filter device in an up-and-down manner, it is more conducive for sewage to pass through the second filter device and the first filter device in sequence and quickly, and the filtering efficiency is higher. Of course, in some other embodiments, the second filter device and the first filter device can also be distributed side by side or in other distribution methods.

[0100] In some embodiments, the second filter device is spaced apart from the first filter device, so that even if the water holes of the second filter device are not aligned with the water holes of the first filter device, it will not affect the normal filtering process of the two filter devices.

[0101] In some embodiments, the first filter device is made of plastic, which has the advantages of being durable, lightweight, low cost and easy to shape. Therefore, using a first filter device made of plastic can make the production and processing of the first filter device easier, more durable, and can also make the overall weight of the sewage tank smaller.

[0102] In some embodiments, the material of the second filter device is waterproof hard cardboard. The waterproof hard cardboard is low in cost, has good load-bearing capacity, and has good structural strength. Therefore, the second filter device made of waterproof hard cardboard is very suitable as a disposable filter device with low consumption cost. In addition, since the hard cardboard is recyclable and degradable, it is more environmentally friendly.

[0103] In some embodiments, the second filter device has at least partially different functions from the first filter device. For example, the first filter device may be a filter device with maximized capacity, a filter device that can gather solid waste, or a filter device that prevents waste from entering the air suction channel, and the second filter device may be a disposable filter device, a filter device that can gather solid waste, or a filter device that prevents waste from entering the air suction channel. In this embodiment, the second filter device and the first filter device are designed to have different functions, so that users can choose whether to use the second filter device according to actual needs.

[0104] Taking the first filter device as a filter device with maximized capacity, the second filter device as a disposable filter device, a filter device that can gather solid waste, and a filter device that prevents waste from entering the air suction channel as an example, the following lists some possible usage scenarios of a cleaning device (taking a floor scrubber) using a sewage tank of this embodiment:

[0105] 1. When the user only needs to clean a small area, the user can choose to install the second filter device with the function of gathering solid garbage into the box for use, so as to prevent the garbage in the sewage tank from spreading everywhere, making it more convenient for the user to clean the box and the filter device after the cleaning task is completed;

[0106] 2. When the user needs to clean a large area, the user can choose to remove the second filter device and let the first filter device with the largest capacity filter. This will allow the sewage tank to collect a larger amount of solid waste, avoiding the situation where the filter device has a small capacity and the floor scrubber is full in a short time. This will reduce the number of times the user has to stop cleaning the filter device during the entire cleaning process, allowing the user to complete the cleaning task faster and improve cleaning efficiency.

[0107] 3. When the user needs to clean the area where there is easily floating garbage, the user can choose to install the second filter device that can prevent garbage from entering the air suction channel into the box for use. This can prevent the easily floating garbage in the sewage tank from being sucked into the air suction channel and prevent the negative pressure device (such as the fan) from being damaged by the garbage;

[0108] 4. If the user does not want to clean the sewage tank or filter device after using the floor scrubber (for example, in the cold winter), the user can choose to install a disposable second filter device in the box for use. In this way, after using the floor scrubber, the user only needs to take out the disposable filter device containing solid waste in the box and throw it away directly, which can save the user the trouble of cleaning the sewage tank and make it more convenient for the user to use; and, the user only needs to replace it with a new disposable filter device or other filter device for the user to continue using it next time.

[0109] In addition, the structural scheme of the multiple filtering devices included in the sewage tank of this embodiment can adopt the scheme of the filtering device in any embodiment of the above-mentioned solid waste box. For details, please refer to the embodiments of the above-mentioned solid waste box, which will not be repeated again.

[0110] The utility model also provides a cleaning device, comprising a cleaning main unit and any one of the above-mentioned sewage tanks, wherein the cleaning main unit has a sewage recovery pipeline, and the sewage recovery pipeline is connected to the sewage inlet 11. Since the cleaning device adopts all the technical solutions of all the above-mentioned sewage tank embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0111] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
