[0041] 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 this 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.

[0042] The utility model provides a solid waste box, which is mainly used in a sewage tank of a cleaning device to separate solid and liquid from the garbage entering the sewage tank, so as to collect and store 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.

[0043] Reference Figure 1In this embodiment, the solid waste box includes a box body 10, the box body 10 is provided with a sewage inlet 11 and a sewage outlet 12, and the solid waste box also includes a plurality of different filter devices, one of the plurality of filter devices is detachably installed in the box body 10, and the filter device in the box body 10 is located between the sewage inlet 11 and the sewage outlet 12. Among them, different filter devices have different functions. For example, the plurality of filter devices may include a filter device with maximum capacity, a filter device that can gather solid waste, a filter device that can prevent waste from entering the air suction channel, and a filter device that is convenient for users to clean the box body 10, or a disposable filter device, etc. Each filter device can be detachably installed in the box body 10, and the installation method of each filter device and the box body 10 can be the same or different.

[0044] In some embodiments, each filter device is detachably mounted with the box body 10 in the same manner, so that the structural design of the box body 10 for mounting and matching the filter device can be reduced and simplified. It is only necessary to set a set of connection structures on the box body 10, and to set a structure adapted to the connection structure on each filter device. Among them, the detachable assembly method of the filter device and the box body 10 can be selected from some assembly methods with fast disassembly and good stability. In this way, under the premise of ensuring the stable function of the solid waste box, it is more convenient for users to disassemble and replace the filter device by themselves, thereby improving the convenience of use.

[0045] When the solid waste box of this embodiment is used in a cleaning device, the working process of the solid waste box is as follows: the cleaning device allows the solid-liquid mixture to flow in from the sewage inlet 11 of the box body 10, and then passes through the filter device in the box body 10 for filtering, leaving the solid waste on the filter device, and the sewage flows through the filter device and flows out from the sewage outlet 12 of the box body 10 to the liquid storage bin of the sewage tank of the cleaning device.

[0046] The following lists some possible usage scenarios of the cleaning device (taking a floor scrubber as an example) using the solid waste box of this embodiment in actual use:

[0047] 1. When the user only needs to clean a small area, the user can choose to assemble a filter device that can gather 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;

[0048] 2. When the user needs to clean a large area, the user can choose to install the largest capacity filter device into the box body 10 for use. This allows the solid waste box to collect a larger amount of solid waste, avoiding the situation where the filter device has a small capacity and causes the floor scrubber to be full in a short time of use, 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.

[0049] 3. When the user needs to clean an area where there is easily floating garbage, the user can choose to assemble a filtering device that can prevent garbage from entering the suction channel into the box body 10 for use. This can prevent easily floating garbage in the solid garbage box from being sucked into the suction channel and prevent the negative pressure device (such as the fan) from being damaged by the garbage.

[0050] 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 a cold winter), the user can choose to assemble a disposable filter device 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, 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.

[0051] The technical solution of the solid waste box of this embodiment is to equip the solid waste box with a plurality of different filtering devices, and select a filtering device from them to be installed in the box body 10 of the solid waste box, and the filtering device can be disassembled and removed from the box body 10; when the user uses the cleaning equipment (such as a floor scrubber) using the solid waste box of the utility model, the user can switch and select the corresponding filtering device to be installed in the box body 10 for use according to the current filtering needs, so that the sewage tank of the cleaning equipment can achieve the required filtering function, that is, the cleaning equipment can achieve a variety of filtering effects, thus meeting the user's more different filtering function needs.

[0052] Combined with reference Figure 5 In some embodiments, the box body 10 is further provided with an opening K for the filter device to dump garbage or take out the filter device. In this embodiment, the opening K is provided to facilitate the user to clean solid garbage and replace the filter device. For example, when the filter device is full of solid garbage, after taking out the solid garbage box, the user can dump the garbage in the filter device through the opening K of the box body 10, or disassemble the filter device from the box body 10 and take it out from the opening K to clean the garbage in the filter device, and after cleaning, reinstall the filter device into the box body 10 through the opening K, or disassemble and replace the filter device through the opening K.

[0053] In some embodiments, at least one of the plurality of filtering devices is connected to the box body 10 via a hinge structure 13; Figures 1 to 4 , all the filter devices may be detachably connected to the box body 10 through the hinge structure 13, so that all the filter devices can share the same hinge structure 13 in the box body 10, thereby simplifying the structural design in the box body 10. Of course, only some (for example, one or two) of the filter devices may be detachably connected to the box body 10 through the hinge structure 13, and the remaining filter devices may be detachably connected to the box body 10 through other structural solutions.

[0054] In some embodiments, at least one of the plurality of filter devices is connected to the box body 10 through a snap-fit ​​structure; or, one of the plurality of filter devices is interference fit with the inner wall of the box body 10. All filter devices may be detachably connected to the box body 10 through a snap-fit ​​structure; all filter devices may be detachably assembled with the box body 10 through an interference fit with the inner wall of the box body 10; some of the filter devices may be detachably connected to the box body 10 through a snap-fit ​​structure, and the other filter devices may be detachably assembled with the box body 10 through an interference fit with the inner wall of the box body 10; some of the filter devices may be detachably connected to the box body 10 through a hinge structure 13, some of the filter devices may be detachably connected to the box body 10 through a snap-fit ​​structure, and the remaining filter devices may be detachably assembled with the box body 10 through an interference fit with the inner wall of the box body 10.

[0055] In some embodiments, the installation method between multiple filter devices and the box body 10 is the same; for example, two or more filter devices among all the filter devices are detachably connected to the box body 10 through a hinge structure 13 / clip structure, or two or more filter devices among all the filter devices are detachably assembled with the box body 10 through an interference fit with the inner wall of the box body 10.

[0056] In some embodiments, at least two of the multiple filter devices are made of different materials; for example, some filter devices are made of plastic, some filter devices are made of water-resistant paper, or some filter devices are made of polymer materials, etc.; among them, the filter device that needs to be recycled and reused can use a durable material, while the disposable filter device can use a low-cost paper material or other low-cost material.

[0057] In some embodiments, the plurality of filter devices have different shapes. For example, the plurality of filter devices may include plate-shaped filter devices, box-shaped filter devices, semi-frame-shaped filter devices, or filter devices of other specific shapes.

[0058] Reference Figure 1In some embodiments, the plurality of filtering devices include a first filtering device, the first filtering device includes a filter plate 211, and the filter plate 211 is provided with a water hole; when the first filtering device is installed in the box body 10, the filter plate 211 is arranged at the bottom of the box body 10, and a first interval space S1 is formed between the filter plate 211 and the bottom wall 14 of the box body 10, and the sewage outlet 12 is connected to the first interval space S1, and the first interval space S1 flows out between the filter plate 211 and the bottom wall 14 of the box body 10, so that the sewage in the solid-liquid mixture entering the solid waste box can smoothly pass through the filter plate 211, 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 this embodiment, the first filter device is a filter plate 211 with a plate-like structure, and the filter plate 211 is located at the bottom of the box body 10 when assembled in the box body 10. When the solid waste box is in operation as a cleaning device, all solid waste is filtered and retained on the filter plate 211. The space formed by the filter plate 211 and the inner wall of the box body 10 and located between the filter plate 211 and the sewage inlet 11 is a solid waste storage space. Therefore, the first filter device is a filter device that enables the solid waste box to have a large solid waste capacity, that is, the first filter device is a filter device that enables the solid waste box to achieve a large capacity function.

[0059] Reference Figure 3 In some embodiments, the plurality of filter devices include a second filter device, and the second filter device includes a filter frame 221 provided with a water hole; when the second filter device is installed in the box body 10, 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. The solid-liquid mixture entering from the sewage inlet 11 first reaches the first chamber V1, and then is filtered by the filter frame 221. The solid waste in the solid-liquid mixture remains in the first chamber V1, and the sewage in the solid-liquid mixture flows into the second chamber V2 through the filter frame 221, and then flows out of the box body 10 through the sewage outlet 12. In this embodiment, the second filter device is a filter frame 221 of a frame-like structure, and the filter frame 221 is used to divide the internal space of the box body 10 into a first cavity V1 and a second cavity V2, so that after being filtered by the filter frame 221, all 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 equipment. At the same time, since the air suction port 15 is connected to the second cavity V2, the material entering the second cavity V2 has filtered the large particles of garbage through the water hole. Therefore, the configuration of this application can also prevent the air suction port 15 from being blocked by large garbage.

[0060] In some embodiments, the filter frame 221 includes a bottom plate and two side plates arranged opposite to each other at intervals, and water holes are provided on the bottom plate and / or the side plates. That is, the filter frame 221 of this embodiment is a semi-frame structure 16 surrounded by two side plates and the bottom plate. When the filter frame 221 is filtering, the sewage flows out from the water holes on the bottom plate and / or the water holes on the side plates to the second chamber V2. It is preferred that water holes are provided on both the bottom plate and the side plates of the filter frame 221, 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 or the side plates 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.

[0061] In some embodiments, the bottom plate of the filter frame 221 is provided with a water hole, and the bottom plate of the filter frame 221 is spaced apart from the bottom wall 14 of the box body 10. By placing the bottom plate of the filter frame 221 close to the bottom wall 14 of the box body 10, 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 of the filter frame 221 is spaced apart from the bottom wall 14 of the box body 10 to ensure the smoothness of the sewage passing through the water hole on the bottom plate, so that the sewage can flow out of the first cavity V1 faster.

[0062] 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, which can reduce the height of the filter frame 221, better facilitate the disassembly and assembly of the filter frame 221, and effectively reduce the cost of the filter frame 221; 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.

[0063] Reference Figure 4 In some embodiments, the plurality of filtering devices include a third filtering device, the third filtering device includes a filter box 231 with an open top side, and the bottom and / or side walls of the filter box 231 are provided with water holes; when the third filtering device is installed in the box body 10, the filter box 231 is arranged at the bottom of the box body 10, the bottom of the filter box 231 covers the bottom wall 14 of the box body 10, and forms a second partition space S2 between the bottom wall 14 of the box body 10, and the sewage outlet 12 is connected to the second partition space S2.

[0064] In this embodiment, the third filter device adopts a filter box 231 of a box-shaped structure, and the solid-liquid mixture entering from the sewage inlet 11 all falls into the filter box 231. After the filtering action of the filter box 231, all the solid waste remains in the filter box 231, and the sewage flows out from the water holes on the bottom and / or side wall of the filter box 231 to the second interval space S2, and then flows out of the box body 10 from the sewage outlet 12. The third filter device adopts the filter box 231 solution, so that after filtering, all the solid waste is collected in the filter box 231 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 231, which reduces the trouble of cleaning the inner wall of the box body 10. In addition, the filter box 231 can be made of a low-cost material (such as a water-resistant paper material), so that the filter box 231 can be used once. After using the cleaning device, the user can directly take out the filter box 231 and throw it away, and then replace it with a new filter box 231 to continue using it. In this way, the user does not need to clean the filter box 231 or the box body 10, which is easier to use. At the same time, because the side wall of the filter box 231 extends upward from the bottom of the filter box 231, the filtered solid waste can be stably retained in the filter box 231, and because of the existence of the opening K, the design of the filter box 231 can prevent the solid waste from falling from the opening K when the user takes the solid waste box out of the sewage tank.

[0065] In some embodiments, when the filter box 231 is installed in the box body 10, the periphery of the box opening of the filter box 231 fits against the inner wall of the box body 10 to prevent solid waste from passing through the gap between the filter box 231 and the inner wall of the box body 10.

[0066] Reference Figure 2 In some embodiments, the filter device is provided with at least one air-permeable baffle 212, which is provided between the air suction port 15 and the sewage inlet 11. In this embodiment, the air-permeable baffle 212 is 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. The air-permeable baffle 212 can be a grille plate, a mesh plate, etc. In this embodiment, Figure 2 The filter device in the embodiment is a filter device that can prevent solid waste from entering the air suction channel by adding a breathable baffle 212 to the filter plate 211. The breathable baffle 212 is connected to the filter plate 211 by a vertically extending connecting plate or connecting strip. The filter plate 211 is described in detail in Figure 2 Description of the illustrated embodiment.

[0067] It should be noted that the air-permeable baffle 212 of this embodiment can also be combined with the structural solutions of the filter devices of other embodiments to form a new structural solution of the filter device. Figure 3 The filter frame 221 and Figure 4The structure of the air-permeable baffle 212 can be added to the structure of the filter box 231 shown.

[0068] In conjunction with the accompanying drawings of the aforementioned embodiments, Figure 6 and Figure 7 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. 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.

[0069] The utility model also proposes a sewage tank, including a tank body and a plurality of different filtering devices, the tank body including a sewage inlet; one of the plurality of filtering devices is detachably installed in the tank body, and the filtering device in the tank body divides the tank body into a solid waste bin and a liquid storage bin, and the sewage inlet is connected to the solid waste bin. Among them, different filtering devices have different functions. For example, the plurality of filtering devices may include a filtering device with maximized capacity, a filtering device that can gather solid waste, a filtering device that can prevent waste from entering the air suction channel, and a filtering device that is convenient for users to clean the tank body, or a disposable filtering device, etc. Each filtering device can be detachably installed in the tank body, and the installation method of each filtering device and the tank body can be the same or different.

[0070] In some embodiments, each filter device is detachably mounted with the housing in the same manner, so that the structural design of the housing and the filter device installation can be reduced and simplified. It is only necessary to set a set of connection structures on the housing, and set a structure that is compatible with the connection structure on each filter device. Among them, the detachable assembly method of the filter device and the housing can be selected from some assembly methods that are fast to disassemble and have good stability. In this way, under the premise of ensuring the stable function of the sewage tank, it is more convenient for users to disassemble and replace the filter device by themselves, thereby improving the convenience of use.

[0071] When the sewage tank of this embodiment is used in a cleaning device, a solid-liquid mixture flows into the tank from the sewage inlet and is filtered by a filter device in the tank, leaving solid waste on the filter device and sewage flowing through the filter device to be stored in a liquid storage tank.

[0072] The following lists some possible usage scenarios of the cleaning equipment (taking a floor scrubber as an example) using the sewage tank of this embodiment:

[0073] 1. When the user only needs to clean a small area, the user can choose to install a filter device that can gather solid waste into the box for use. This can prevent the waste 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;

[0074] 2. When the user needs to clean a large area, the user can choose to install the largest capacity filter device into the box for use. 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 causes the floor scrubber to be full in a short time. This will reduce 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.

[0075] 3. When the user needs to clean the area where there is easily floating garbage, the user can choose to install a filter device that can prevent the garbage from entering the suction channel into the box for use. This can prevent the easily floating garbage in the sewage tank from being sucked into the suction channel and prevent the negative pressure device (such as the fan) from being damaged by the garbage.

[0076] 4.
