[0002] This application claims priority to Chinese patent application filed on January 27, 2025, with application number 202520175192 3, entitled "Sewage Tank and Cleaning Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of clean technology, and in particular to a wastewater tank and cleaning equipment. Background Technology

[0004] With the development of science and technology and the improvement of living standards, household cleaning equipment has become increasingly popular, reducing the burden of housework.

[0005] In related technologies, taking floor scrubbers as an example, floor scrubbers perform wet cleaning of the surface to be cleaned. The dirt generated during cleaning is collected in a wastewater tank. Dirt can easily breed bacteria and cause the wastewater tank to smell, affecting the user experience. Currently, there are methods to remove odors by placing deodorizing devices inside the wastewater tank. However, these deodorizing devices are either fixed inside the wastewater tank and cannot be removed, or they are inconvenient to remove, resulting in a poor user experience. Summary of the Invention

[0006] In view of this, the present application provides a sewage tank and cleaning device to solve at least one problem existing in the background art, which can at least facilitate the disassembly of the deodorization module, facilitate the cleaning of the deodorization module, reduce or even avoid dirty hands, and improve the user experience.

[0007] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0008] A first aspect of this application provides a sewage tank, the sewage tank comprising:

[0009] The container has a sewage chamber, and a sewage inlet and a sewage dumping outlet respectively connected to the sewage chamber;

[0010] A lid is detachably attached to the box body to open or close the dirty dumping port;

[0011] A solid-liquid separator is located inside the tank and connected to the tank cover. The solid-liquid separator can be disassembled and installed together with the tank cover. The outlet of the sewage inlet channel is located above the solid-liquid separator. The sewage output from the outlet of the sewage inlet channel flows to the bottom of the sewage chamber after being separated by the solid-liquid separator under the action of gravity. The solid-liquid separator is used to filter out some of the solid waste in the sewage.

[0012] The deodorization module is located inside the sewage chamber and has a hollow shell for storing deodorizing agent. The deodorization module is connected to the solid-liquid separator and the hollow shell is located below the solid-liquid separator and extends toward the bottom of the sewage chamber.

[0013] The deodorization module is located inside the sewage chamber. Sewage can come into contact with the deodorizing agent inside the deodorization module through the perforations of the hollow shell. The deodorizing agent can destroy the cell structure of bacteria, kill bacteria, and achieve the deodorization effect. It can also deodorize through odor adsorption.

[0014] Disinfectants can be silver ion bactericides or activated carbon deodorizers, such as silver ion slow-release granules or activated carbon granules, but are not limited to these.

[0015] Since the deodorization module is connected to the solid-liquid separator, which in turn is connected to the tank cover, the operator can operate the tank cover to remove the deodorization module from the sewage chamber, achieving simultaneous disassembly of the deodorization module and the tank cover. The disassembly method is simple and convenient, eliminating the need to reach into the tank to disassemble the deodorization module and avoiding the situation of getting hands dirty over a large area.

[0016] After the dirt is separated by the solid-liquid separator, some solid waste (including hair and other easily tangled waste) is trapped above the separator, while the wastewater mixed with some solid waste flows through the separator to the bottom of the wastewater chamber. Because the deodorization module is located below the solid-liquid separator, hair and other easily tangled waste are trapped above it, thus greatly reducing the possibility of the deodorization module becoming entangled and clogged by waste.

[0017] In some applications, such as when the sewage tank reaches its maximum water level, or when sewage needs to be emptied after each self-cleaning cycle, the sewage tank can be removed from the cleaning equipment first. Then, the tank cover can be removed to open the waste disposal port, allowing sewage and solid waste to be emptied and the inside of the sewage chamber to be cleaned. With the deodorization module removed along with the tank cover, almost all of the parts of the deodorization module that come into contact with the sewage are exposed, allowing for cleaning of the dirtier areas of the deodorization module and the tank cover.

[0018] Optionally, the solid-liquid separator is provided with a water inlet, which is used to guide the flow direction of the liquid on the solid-liquid separator. The deodorization module is located in the guiding direction of the water inlet, so that the liquid inlet is drawn by the water inlet and flows to the bottom of the sewage chamber after passing through the deodorization module.

[0019] Optionally, the top surface of the hollow shell is provided with a first through hole to receive the liquid drained by the water inlet.

[0020] Optionally, the water inlet is located at the lowest point of the solid-liquid separator.

[0021] Optionally, the water intake section is provided in the form of a groove, the groove is provided with filter holes, and the filter holes face the deodorization module.

[0022] Optionally, the distance between the bottom surface of the hollow shell and the bottom surface of the sewage chamber is less than 1 cm.

[0023] Optionally, the hollow shell has a second through hole at least at the bottom.

[0024] Optionally, the hollow shell is cylindrical or composed of multiple cylinders of different radii stacked together. The maximum diameter of the hollow shell is 20-32mm, the minimum diameter is 12-19mm, and the height is 80-134mm.

[0025] Optionally, the solid-liquid separator is inclinedly disposed inside the housing, and the deodorization module is located below the lowest position of the solid-liquid separator.

[0026] Optionally, the hollow shell is columnar; the cross-section of the hollow shell gradually tapers from bottom to top, or the cross-section at the bottom of the hollow shell is larger than the cross-section at the top.

[0027] Optionally, the deodorization module can be detachably connected to the solid-liquid separation component, and the detachable connection method of the deodorization module includes snap-fit ​​connection, magnetic connection, threaded connection or plug-in connection.

[0028] Optionally, the wastewater tank further includes an in-situ detection module, which is used to detect whether the deodorization module is installed in place.

[0029] A second aspect of this application provides a sewage tank, the sewage tank comprising:

[0030] The container has a sewage chamber, and a sewage inlet and a sewage dumping outlet respectively connected to the sewage chamber;

[0031] A lid is detachably attached to the box body to open or close the dirty dumping port;

[0032] The deodorization module is located inside the sewage chamber. The deodorization module is columnar and has a hollow shell for storing deodorizing agent. Its top extends to the sewage discharge port and its bottom extends to the bottom of the sewage chamber. The deodorization module is detachably connected to the bottom surface of the sewage chamber, the inner wall of the box, or the outer wall of the sewage inlet channel.

[0033] If the sewage tank is not equipped with a solid-liquid separation device, the deodorization module can be detachably connected to the bottom surface of the sewage chamber, the inner side wall of the tank, or the outer side wall of the sewage inlet channel.

[0034] The maximum water level in the sewage chamber is below the dirty waste outlet. The top of the deodorizing module extends to the dirty waste outlet, ensuring that at least a portion of the top of the deodorizing module is not submerged in sewage. This reduces the likelihood of the top of the deodorizing module being contaminated by sewage, thus minimizing the possibility of dirty hands when disassembling the module. Optionally, the top of the deodorizing module is flush with the dirty waste outlet, or the top of the deodorizing module extends beyond the dirty waste outlet.

[0035] A third aspect of this application provides a sewage tank, the sewage tank comprising:

[0036] The container has a sewage chamber, and a sewage inlet and a sewage dumping outlet respectively connected to the sewage chamber;

[0037] A lid is detachably attached to the box body to open or close the dirty dumping port;

[0038] The deodorization module, located within the sewage chamber, has a perforated shell. This perforated shell is annular in shape and is used to store the deodorizing agent. The perforated shell is fitted over the sewage inlet channel. The annular shape of the perforated shell increases the contact area with the sewage, thus improving the deodorization effect.

[0039] The annular perforated housing can be fitted tightly against the outer wall of the sewage inlet channel. For example, the annular perforated housing can be sleeved on the outside of the sewage inlet channel, and the perforated housing can be fixedly connected by the friction between it and the outer wall of the sewage inlet channel. This sleeved connection method facilitates the disassembly of the deodorization module.

[0040] Optionally, the wastewater tank further includes a solid-liquid separator located within the tank body. The outlet of the wastewater inlet channel is located above the solid-liquid separator. The wastewater discharged from the outlet of the wastewater inlet channel flows to the bottom of the wastewater chamber after being separated by the solid-liquid separator under gravity. The solid-liquid separator is used to filter some of the solid waste in the wastewater. The perforated shell is located below the solid-liquid separator and extends along the axis of the wastewater inlet channel to the bottom surface of the wastewater chamber. A fourth aspect of this application provides a cleaning device comprising: a floor brush structure, a body assembly, and the wastewater tank described in any of the first aspects of the embodiment. The body assembly is rotatably connected to the floor brush structure, and the wastewater tank is mounted on the floor brush structure or the body assembly. The technical effects of this embodiment can be found in the foregoing embodiments and will not be repeated here.

Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. When used herein, the singular forms “a,” “an,” and “the” may also be intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “comprising,” when used in this specification, identifies the presence of the stated features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups. When used herein, the term “and / or” includes any and all combinations of the associated listed items.

[0055] It should be understood that when a structure is referred to as "connected to" or "coupled to" other structures, it may be directly connected to or coupled to other structures, or there may be intervening structures. Conversely, when a structure is referred to as "directly connected to" or "directly coupled to" other structures, there are no intervening structures. It should be understood that although the terms first, second, third, etc., may be used to describe various elements, components, areas, layers, and / or portions, these elements, components, areas, layers, and / or portions should not be limited by these terms. These terms are merely used to distinguish one from another. Therefore, without departing from the teachings of this application, the first element, component, area, layer, or portion discussed below may be referred to as a second element, component, area, layer, or portion. And the discussion of a second element, component, area, layer, or portion does not imply that the first element, component, area, layer, or portion necessarily exists in this application.

[0056] The cleaning equipment in this application embodiment can be a floor scrubber, a sweeper and mop combo, etc., but is not limited to these.

[0057] For ease of description, we will use a floor scrubbing machine as an example below.

[0058] Referring to Figure 1, the floor scrubber includes a brush structure 120, a body assembly 110, and a wastewater tank 130. During cleaning, the user can hold the machine on the body assembly 110 and swing it to move the brush structure 120 forward, causing it to rub against the surface to be cleaned. Surfaces to be cleaned include floors, carpets, walls, tabletops, etc.

[0059] Optionally, the floor scrubber may also include a clean water tank 140, which can provide cleaning liquid to the roller brush to wet the roller brush so that the roller brush can wet the stains on the surface to be cleaned during the cleaning process, reduce the adhesion of the stains and improve the cleaning effect.

[0060] Wastewater tank 130 is used to collect dirt from the cleaning process, which is generally a mixture of solids and liquids.

[0061] The cleaning equipment may also include a suction device that provides negative pressure, under which dirt on the surface to be cleaned is sucked into the wastewater tank 130.

[0062] The wastewater tank 130 in this application embodiment can be a wastewater tank 130 with solid-liquid separation function or a wastewater tank 130 without solid-liquid separation function.

[0063] A wastewater tank 130 without solid-liquid separation function includes: a tank body 131, a tank cover 132, and a deodorization module 134. The tank body 131 has a wastewater chamber 1311, and a wastewater inlet 133 and a wastewater discharge port 1314 respectively communicating with the wastewater chamber 1311. The tank cover 132 is detachably connected to the tank body 131 to open or close the wastewater discharge port 1314. The deodorization module 134 is located inside the wastewater chamber 1311 and has a perforated shell containing a deodorizing agent. The deodorizing agent can destroy the cell structure of bacteria, kill bacteria, and achieve a deodorizing effect. Alternatively, the deodorizing agent can deodorize by adsorbing odors.

[0064] Since it lacks a solid-liquid separation function, solid waste such as hair and fibrous fabrics in the sewage can easily become entangled on the outer wall of the sewage inlet channel 133 or the deodorization module 134. To reduce or even avoid entanglement on the outer wall of the sewage inlet channel 133 or the deodorization module 134, a solid-liquid separation component 1321 can be added to the aforementioned sewage tank 130 structure. The solid-liquid separation component 1321 is used to achieve the solid-liquid separation function. Therefore, the sewage tank 130 in this embodiment can also be a sewage tank 130 with a solid-liquid separation function.

[0065] The following sections describe the wastewater tank 130 with solid-liquid separation function and the wastewater tank 130 without solid-liquid separation function.

[0066] Example 1

[0067] This application embodiment describes a wastewater tank 130 with solid-liquid separation function based on the foregoing.

[0068] Referring to Figures 2 and 3, the wastewater tank 130 of this application includes: a tank body 131, a tank cover 132, a solid-liquid separator 1321, and a deodorization module 134. The tank body 131 has a wastewater chamber 1311, and a wastewater inlet 133 and a wastewater discharge port 1314 respectively connected to the wastewater chamber 1311. The tank cover 132 is detachably connected to the tank body 131 to open or close the wastewater discharge port 1314. The solid-liquid separator 1321 is located inside the tank body 131 and connected to the tank cover 132. The outlet 1332 of the wastewater inlet 133 is located... Above the solid-liquid separator 1321, the dirt output from the outlet 1332 of the sewage inlet channel 133 flows to the bottom of the sewage chamber 1311 after being separated by the solid-liquid separator 1321 under the action of gravity. The solid-liquid separator 1321 is used to filter out some of the solid waste in the dirt. The deodorization module 134 is located in the sewage chamber 1311. It has a hollow shell for storing deodorizing agent. The deodorization module 134 is connected to the solid-liquid separator 1321. The hollow shell is located below the solid-liquid separator 1321 and extends towards the bottom of the sewage chamber 1311.

[0069] For example, referring to Figure 4, the housing 131 is cylindrical, including a generally annular sidewall 1312 that encloses a sewage chamber 1311. The top opening of the sewage chamber 1311 is a wastewater dumping port 1314. As shown in Figure 3, the inlet 1331 of the sewage inlet channel 133 may be located at the bottom of the housing 131, and the sewage inlet channel 133 may be located approximately in the middle of the sewage chamber 1311, but is not limited thereto.

[0070] The deodorization module 134 is located inside the sewage chamber 1311. Sewage can come into contact with the deodorizing agent inside the deodorization module 134 through the perforation 1341 of the hollow shell to achieve the sterilization and deodorization of sewage.

[0071] Disinfectants can be silver ion bactericides or activated carbon deodorizers, such as silver ion slow-release granules or activated carbon granules, but are not limited to these.

[0072] Since the deodorization module 134 is connected to the solid-liquid separator 1321, and the solid-liquid separator 1321 is connected to the cover 132, the operator can operate the cover 132 to remove the deodorization module 134 from the sewage chamber 1311, achieving simultaneous disassembly of the deodorization module 134 and the cover 132. The disassembly method is simple and convenient. There is no need to reach into the chamber 131 to disassemble or install the deodorization module 134, avoiding the situation of getting large areas of hands dirty.

[0073] After the dirt is separated by the solid-liquid separator 1321, some solid waste (including easily tangled waste such as hair) is trapped above the solid-liquid separator 1321, while the wastewater mixed with some solid waste flows through the solid-liquid separator 1321 to the bottom of the wastewater chamber 1311. Since the deodorization module 134 is located below the solid-liquid separator 1321, easily tangled waste such as hair is trapped above it by the solid-liquid separator 1321, thus greatly reducing the possibility of the deodorization module 134 being entangled by waste.

[0074] In some application scenarios, such as when the sewage in the sewage tank 130 reaches the maximum water level, or when sewage needs to be emptied after each self-cleaning cycle, the sewage tank 130 can be removed from the cleaning equipment first, and then the tank cover 132 can be removed to open the dirty waste disposal port 1314. Sewage and solid waste can be emptied through the dirty waste disposal port 1314, and the inside of the sewage chamber 1311 can be cleaned. After the deodorization module 134 is removed along with the tank cover 132, almost all of the part of the deodorization module 134 that comes into contact with sewage can be exposed, and the dirtier parts of the deodorization module 134 and the tank cover 132 can also be cleaned.

[0075] In some alternative embodiments, the solid-liquid separator 1321 is provided with a water inlet, which is used to guide the flow direction of the liquid on the solid-liquid separator 1321. The deodorization module 134 is located in the guiding direction of the water inlet, so that the liquid inlet is drawn by the water inlet and flows to the bottom of the sewage chamber 1311 after passing through the deodorization module 134.

[0076] The solid-liquid separator 1321 forms a dominant flow channel for downward flow of sewage through the water inlet section; in other words, the water inlet section is the main flow channel for downward flow of sewage. For example, if sewage flows downward from multiple locations on the solid-liquid separator 1321, the location with the largest flow rate is the water inlet section. By placing the deodorization module 134 in the guiding direction of the water inlet section, more sewage can flow through the deodorization module 134, allowing the sewage to fully contact the deodorization module 134. The sewage can undergo preliminary sterilization and deodorization before falling to the bottom of the sewage chamber 1311. Thus, even if the sewage volume is small and only a portion of the bottom area of ​​the deodorization module 134 contacts the sewage, the sterilization and deodorization effect can be improved by utilizing the contact between the sewage and the deodorization module 134 during the downward flow.

[0077] In some alternative embodiments, the top surface of the hollow shell is provided with a first through hole to receive the liquid drained by the water inlet.

[0078] The first through hole on the top surface of the perforated shell increases the perforated area of ​​the shell, increasing the chance of contact between sewage and deodorizer. Furthermore, since the sewage flows from top to bottom, it can easily flow directly into the perforated shell through the first through hole and then out, further improving the deodorization effect. Specifically, the sewage diverted by the water inlet can at least partially enter the deodorization module 134 through the first through hole, contacting the deodorizer inside the module 134. After being sterilized by the deodorizer, the sewage can flow from the perforation 1341 of the perforated shell to the bottom of the sewage chamber 1311.

[0079] Figure 5 illustrates, exemplarily, that the perforations 1341 are multiple small holes distributed around the periphery of the perforated shell. These perforations 1341, formed as circular holes, can have equal or varying diameters. The multiple perforations 1341 can be evenly distributed on the sidewalls of the perforated shell or non-uniformly distributed. Referring to Figure 5, there can be more perforations 1341 below the deodorizing module 134, while there can be relatively fewer perforations above the deodorizing module 134.

[0080] It is understandable that the cutout 1341 is not limited to the circle shown in the picture; it can also be a rectangle, triangle, pentagon, irregular shape, etc.

[0081] The first through hole on the top surface of the perforated shell can be a single hole with a large diameter or multiple holes with smaller diameters. Both the first through hole and the perforation 1341 are connected to the inner cavity of the perforated shell where the deodorant is stored.

[0082] In some alternative embodiments, the water inlet is located at the lowest point of the solid-liquid separator 1321.

[0083] Referring to Figure 3, the solid-liquid separator 1321 is an inclined separation plate with multiple filter holes on its surface to allow filtered wastewater to pass through. The lowest point of the solid-liquid separator 1321 is the dominant flow channel for wastewater, which is the water inlet. The deodorization module 134 is located below the lowest point of the solid-liquid separator 1321. Most of the filtered wastewater can flow downwards through the lowest point of the solid-liquid separator 1321 into the deodorization module 134, which helps to improve the deodorization effect.

[0084] In some alternative implementations, the water inlet is provided in the form of a groove with filter holes facing the deodorization module 134.

[0085] The solid-liquid separator 1321 has a through hole 1323 that aligns with the outlet 1332 of the inlet channel 133. A groove can be arranged around the through hole 1323. Dirt flows out sequentially through the outlet 1332 of the inlet channel 133 and the through hole 1323, and then spreads around the through hole 1323 above the solid-liquid separator 1321. Some solid waste is larger than the filter hole and is retained, while solid waste and sewage smaller than the filter hole flow through the filter hole to the bottom of the sewage chamber 1311. The groove is called the water inlet section because it is located low and close to the outlet 1332 of the inlet channel 133.

[0086] In some alternative embodiments, the distance between the bottom surface of the perforated housing and the bottom surface of the sewage chamber 1311 is less than 1 cm. Since sewage rises from the bottom of the sewage chamber 1311, the sewage generated in a single cleaning operation may not reach the maximum water level of the sewage chamber 1311, and may only amount to a small quantity. Furthermore, some solid dirt (such as sludge) flowing down with the sewage will accumulate at the bottom of the sewage chamber 1311, resulting in a relatively higher bacterial content in the sewage near its bottom. Maintaining a distance of less than 1 cm between the bottom surface of the perforated housing and the bottom surface of the sewage chamber 1311 allows the bottom of the deodorizing module 134 to contact the bottom of the sewage chamber 1311 as closely as possible, ensuring contact even with small amounts of sewage and guaranteeing effective sterilization and deodorization.

[0087] In some alternative embodiments, the hollow housing has at least a second through hole 1342 at the bottom.

[0088] The second through hole 1342 at the bottom of the perforated shell increases the perforated area of ​​the shell, increasing the chance of contact between sewage and deodorizing agent and improving the deodorization effect. Specifically, the sewage diverted by the water inlet can enter the inner cavity of the deodorization module 134 through the second through hole 1342 at the bottom of the perforated shell, come into contact with the deodorizing agent inside the deodorization module 134, and the sewage sterilized by the deodorizing agent can flow out through the perforation 1341 of the perforated shell.

[0089] The second through hole 1342 at the bottom of the hollow shell can be one, two, three or more. Figure 5 exemplarily shows a hollow shell with multiple small-diameter second through holes 1342 densely distributed at the bottom.

[0090] In some optional embodiments, the perforated shell is cylindrical or composed of multiple stacked cylinders of different radii. The maximum diameter of the perforated shell is 20-32 mm, the minimum diameter is 12-19 mm, and the height is 80-134 mm. This type of perforated shell can extend to the bottom of the sewage chamber 1311, better fitting the sewage chamber 1311 and ensuring deodorization effect.

[0091] For example, the deodorization module 134 shown in Figure 5 consists of two cylinders with different radii stacked together. The upper cylinder has a smaller radius, about 8 mm, while the lower cylinder has a larger radius, about 13 mm. The overall length of the hollow shell (which can be understood as the sum of the heights of the upper and lower cylinders) is 111 mm.

[0092] In some alternative embodiments, the solid-liquid separator 1321 is inclinedly disposed inside the housing 131, and the deodorization module 134 is located below the lowest position of the solid-liquid separator 1321.

[0093] Compared to other positions below the solid-liquid separator 1321, the wastewater flow is greatest below the lowest position of the solid-liquid separator 1321. The deodorization module 134 is located below the lowest position of the solid-liquid separator 1321, which allows more wastewater to come into contact with the deodorizing agent during its descent, thereby improving the deodorization effect.

[0094] In some alternative embodiments, the hollow shell is columnar; the cross-section of the hollow shell gradually tapers from bottom to top (as shown in Figure 6), or the cross-section at the bottom of the hollow shell is larger than the cross-section at the top (as shown in Figure 5).

[0095] Based on the foregoing description, sewage rises from the bottom of sewage chamber 1311, and the bottom of sewage chamber 1311 preferentially collects sewage, with a relatively higher bacterial content in the sewage near its bottom. The perforated shell's cross-section gradually narrows from bottom to top, or the cross-section at the bottom of the perforated shell is larger than the cross-section at the top, both of which provide a larger bottom space. This allows the bottom of the perforated shell to store more deodorizing agent, effectively improving the deodorization effect on the bottom of sewage chamber 1311.

[0096] For example, the deodorization module 134 is a deodorizing rod, or the deodorization module 134 includes a deodorizing box and a mounting part. The deodorizing box is connected to the bottom of the mounting part, which can be generally elongated to allow the deodorization module 134 to extend into the bottom of the sewage chamber 1311. A deodorizing agent is installed inside the deodorizing box, and the deodorization module 134 is mounted to the solid-liquid separator 1321 via the mounting part.

[0097] The deodorization module 134 does not need to have deodorizing agent at all heights because the sewage tank 130 has a maximum sewage capacity. Below the height corresponding to the maximum sewage capacity, there must be sterilization and deodorization particles. In other words, the sterilizing agent is distributed at least at the bottom of the deodorization module 134 near the sewage chamber 1311.

[0098] When configuring the proportion of sterilization and deodorization particles in the cavity of the deodorization module 134, the sterilization dose at the bottom of the deodorization module 134 can be greater than the sterilization dose above it.

[0099] In some alternative embodiments, the deodorization module 134 is detachably connected to the solid-liquid separator 1321. The detachable connection method of the deodorization module 134 includes snap-fit ​​connection, magnetic connection, threaded connection or plug-in connection.

[0100] The deodorization module 134 is detachable from the solid-liquid separator 1321, which allows for easy cleaning of the deodorization module 134 separately, or replacement of the deodorization module 134 with a new one if the deodorization efficiency of the deodorization module 134 fails to meet the requirements.

[0101] In addition, in other alternative embodiments, an outer cover can be provided on the hollow housing. The outer cover can open or close the inner cavity of the hollow housing, where the deodorizer is stored. When the deodorization efficiency of the deodorization module 134 fails to meet the requirements, the outer cover can be opened and a new deodorizer can be replaced. In this way, the hollow housing can be reused, saving on usage costs.

[0102] The snap-fit ​​mechanism includes, but is not limited to: the solid-liquid separator 1321 and the deodorization module 134 are respectively provided with snap-fit ​​grooves and snap-fit ​​protrusions, and the snap-fit ​​protrusions are inserted into or removed from the snap-fit ​​grooves to achieve a detachable connection.

[0103] The plug-in connection includes, but is not limited to: as shown in Figure 3, a tube 1322 is provided below the solid-liquid separator 1321, and the columnar deodorizing module 134 can be inserted into the tube 1322. In order to improve the reliability of the plug-in connection, a protrusion 1343 or a spring arm can be provided at the connection position between the deodorizing module 134 and the solid-liquid separator 1321.

[0104] In some alternative embodiments, the wastewater tank 130 further includes an in-situ detection module for detecting whether the deodorization module 134 is installed in place.

[0105] In-situ detection modules include, but are not limited to, pressure sensors, photoelectric sensors, or vision sensors.

[0106] The presence detection module can alert users whether the deodorization module 134 is currently installed and whether it is installed correctly. It can also evaluate the lifespan of the deodorization module 134 based on the duration it is present, and remind users to replace it with a new one when the module reaches the end of its lifespan. Therefore, the presence detection module can work in conjunction with other control logic of the cleaning equipment to improve the intelligence level of the wastewater tank 130 and enhance the user experience.

[0107] Example 2

[0108] This application describes a wastewater tank 130 without solid-liquid separation function, based on the foregoing. The difference between Embodiment 2 and Embodiment 1 is that the wastewater tank 130 in Embodiment 2 does not have a solid-liquid separation component 1321, but the rest of the structure is the same as in Embodiment 1.

[0109] For example, the sewage tank 130 includes a tank body 131, a tank cover 132, and a deodorization module 134. The tank body 131 has a sewage chamber 1311, and a sewage inlet channel 133 and a dirty dumping port 1314 respectively connected to the sewage chamber 1311. The tank cover 132 is detachably connected to the tank body 131 to open or close the dirty dumping port 1314. The deodorization module 134 is located inside the sewage chamber 1311. The deodorization module 134 is columnar and has a hollow shell for storing deodorizing agent. Its top extends to the dirty dumping port 1314, and its bottom extends to the bottom of the sewage chamber 1311.

[0110] In some embodiments, the deodorization module 134 can be detachably connected to the bottom surface of the sewage chamber 1311, the inner side wall of the box 131 (as shown in Figure 7), or the outer side wall of the sewage inlet channel 133.

[0111] In some alternative embodiments, the deodorization module 134 may also be detachably connected to the lid 132.

[0112] The maximum water level in the sewage chamber 1311 is below the dirty discharge port 1314. The top of the deodorization module 134 extends to the dirty discharge port 1314, ensuring that at least a portion of the top of the deodorization module 134 is not submerged in sewage. This reduces the likelihood of the top portion of the deodorization module 134 being contaminated by sewage, thus minimizing the possibility of dirty hands when disassembling the deodorization module 134. When the deodorization module 134 is detachably connected to the bottom of the sewage chamber 1311, it can be located anywhere between the outer wall of the sewage inlet channel 133 and the inner wall of the housing 131.

[0113] As shown in Figure 4, the inner wall of the housing 131 refers to the side wall 1312 of the housing shown in Figure 4, which encloses the sewage chamber 1311. As shown in Figure 7, the deodorization module 134 is detachably connected to the side wall 1312 of the housing. Detachably connecting the deodorization module 134 to the inner wall of the sewage chamber 1311 not only facilitates the disassembly of the deodorization module 134, but also allows the inner wall of the housing 131 to provide support for the deodorization module 134, improving the reliability of the deodorization module 134 installed in the sewage chamber 1311. Moreover, by detachably connecting the deodorization module 134 to the inner wall of the sewage chamber 1311, one side wall of the deodorization module 134 is almost in contact with the inner wall of the housing 131, making it less likely for solid waste in the sewage to become entangled on the deodorization module 134.

[0114] As shown in Figure 9, when the deodorization module 134 is detachably connected to the outer wall of the sewage inlet channel 133, the outer wall of the sewage inlet channel 133 can also provide support for the deodorization module 134, thereby improving the reliability of the deodorization module 134 installed in the sewage chamber 1311.

[0115] Optionally, the top of the deodorizing module 134 is flush with the height of the waste disposal port 1314, or, as shown in Figure 8, the top of the deodorizing module 134 protrudes beyond the waste disposal port 1314. This further reduces the possibility of the top of the deodorizing module 134 becoming contaminated, and further facilitates the disassembly of the deodorizing module 134. If the top of the deodorizing module 134 protrudes beyond the waste disposal port 1314, the deodorizing module 134 can be disassembled by holding the protruding part, making disassembly simple and convenient while further reducing the possibility of dirty hands.

[0116] The top edge of the inner wall of the sewage chamber 1311 forms a dirty dumping port 1314. Here, "the top of the deodorizing module 134 is flush with the dirty dumping port 1314" means that the top of the deodorizing module 134 is roughly flush with the top edge 1313 (as shown in Figure 4) of the side wall 1312 of the box.

[0117] In some embodiments, based on the foregoing embodiments, as shown in FIG9, the hollow shell can also be annular columnar, and the annular columnar hollow shell is used to store deodorant, and the hollow shell is sleeved on the outside of the sewage inlet channel 133.

[0118] As shown in Figure 9, the annular hollow shell can be tightly fitted to the outer wall of the sewage inlet channel 133. For example, the annular hollow shell can be sleeved on the outside of the sewage inlet channel 133, and the hollow shell can be fixedly connected by the friction between it and the outer wall of the sewage inlet channel 133. This sleeve connection method facilitates the disassembly of the deodorization module 134.

[0119] In some alternative embodiments, the annular perforated housing may be spaced apart from the outer wall of the sewage inlet channel 133.

[0120] It is understandable that, provided there are no contradictions, some implementations of Embodiment 1 and Embodiment 2 can be combined to form new embodiments.

[0121] For example, based on embodiment 2, the sewage tank 130 further includes a solid-liquid separator 1321, which is located inside the tank body 131. The outlet 1332 of the sewage inlet channel 133 is located above the solid-liquid separator 1321. The dirt output from the outlet 1332 of the sewage inlet channel 133 is separated by the solid-liquid separator 1321 under the action of gravity and flows to the bottom of the sewage chamber 1311. The solid-liquid separator 1321 is used to filter some of the solid waste in the dirt. The hollow shell is located below the solid-liquid separator 1321 and extends along the axial direction of the sewage inlet channel 133 to the bottom surface of the sewage chamber 1311.

[0122] For example, based on the above, the deodorization module 134 of the sewage tank 130 with solid-liquid separation function can also be sleeved on the outside of the sewage inlet channel 133, and the deodorization module 134 can also be snapped into the bottom of the sewage chamber 1311. In addition, the deodorization module 134 can also be in the shape of a ring column.

[0123] Example 3

[0125] Referring to Figure 1, in some implementations, the wastewater tank 130 is detachably mounted on the body assembly 110. In this case, the body assembly 110 bears the weight of the wastewater tank 130 and is relatively heavy. In other implementations, the wastewater tank 130 is detachably mounted on the floor brush structure 120, with the floor brush structure 120 bearing the weight of the wastewater tank 130, making the cleaning process more labor-saving.
