Description

TECHNICAL AREA

[0001] The present utility model relates to the technical field of cleaning, in particular to a wastewater tank and a cleaning device. STATE OF THE ART

[0002] With the development of science and technology and the improvement of living standards, household cleaning appliances have become increasingly popular, thereby reducing the burden of human housework.

[0003] In the prior art, a floor cleaning machine is used as an example of a cleaning device. The surface to be cleaned is wet-cleaned using a floor cleaning machine, so that the dirt generated during cleaning is collected in the wastewater tank. Dirt can easily breed bacteria and also cause the wastewater tank to smell, which negatively impacts the user experience. Currently, there is a way to remove odors by placing a deodorizing device in the wastewater tank. However, the deodorizing device is either fixed inside the wastewater tank, making it impossible to remove, or it is inconvenient to remove, which negatively impacts the user experience. CONTENTS OF THE PRESENT USE SAMPLE

[0004] With regard to the problems described above, a wastewater tank and a cleaning device are provided according to the embodiments of the present application, which makes it possible to at least facilitate the disassembly of the deodorization module, which makes cleaning the deodorization module easier, reduces or even avoids contamination of the hands and improves the user experience.

[0005] To achieve the above-mentioned purposes, the following technical solutions are provided in accordance with the embodiments shown in the present application: According to an embodiment of the first aspect of the present application, a wastewater tank is provided, wherein the wastewater tank comprises the following components: a tank body with a wastewater cavity and a wastewater inlet channel and a dirt drain opening, each of which is connected to the wastewater cavity; a tank cap that is detachably connected to the tank body in order to open or close the dirt drain opening; a solid-liquid separator located in the tank body and connected to the tank lid, wherein the solid-liquid separator can be assembled and disassembled together with the tank lid, wherein the outlet of the wastewater inlet channel is located above the solid-liquid separator, wherein the dirt exiting through the outlet of the wastewater inlet channel is separated by the solid-liquid separator under the influence of gravity and then flows to the bottom of the wastewater cavity, wherein the solid-liquid separator is configured to filter out some of the solid waste in the dirt; a deodorization module located in the wastewater cavity and provided with a hollowed-out housing, wherein the hollowed-out housing is configured to store deodorant, wherein the deodorization module is connected to the solid-liquid separator, wherein the hollowed-out housing is arranged below the solid-liquid separator and extends to the bottom of the wastewater cavity.

[0006] The deodorization module is positioned within the wastewater cavity, allowing the wastewater to come into contact with the deodorant inside the module through the hollowed-out housing. The deodorant can destroy the cell structure of bacteria, killing them and thus achieving a deodorizing effect; deodorization can also be achieved through odor adsorption.

[0007] The sterilizing agent may be a silver ion fungicide or an activated carbon deodorant, such as delayed-release silver ion particles and activated carbon particles, but is not limited to these.

[0008] Since the deodorization module is connected to the solid-liquid separator, and the solid-liquid separator is connected to the tank lid, the operator can open the tank lid to remove the deodorization module from the wastewater cavity, thus allowing simultaneous disassembly of both the deodorization module and the tank lid. The disassembly method is simple and convenient, and there is no need to reach inside the tank to install or remove the deodorization module, thereby preventing extensive hand contamination.

[0009] After the solids have been separated by the solid-liquid separator, some of the solid waste (including hair and other easily tangled debris) is trapped above the separator. The wastewater, mixed with some of the 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 debris are trapped above it, greatly reducing the possibility of the deodorization module becoming clogged with debris.

[0010] In some application scenarios, such as when the wastewater in the wastewater tank reaches the maximum water level line or when the wastewater needs to be drained after each self-cleaning cycle, the wastewater tank can first be removed from the cleaning unit. Then, the tank lid can be removed and the dirt drain opening opened, allowing wastewater and solid waste to be drained through the dirt drain and the interior of the wastewater chamber to be cleaned. Once the deodorization module and tank lid have been removed, almost all parts of the deodorization module that come into contact with the wastewater can be exposed, allowing even the dirty areas of the deodorization module and the tank lid to be cleaned.

[0011] Alternatively, it is provided that the solid-liquid separator is provided with a water diversion section, wherein the water diversion section is configured to redirect the flow direction of the liquid on the solid-liquid separator, wherein the deodorization module is arranged in the guidance direction of the water diversion section, so that the liquid diverted by the water diversion section flows to the bottom of the wastewater cavity after passing the deodorization module.

[0012] Alternatively, a first through-hole is provided for on the top of the hollowed-out housing to receive the fluid diverted from the water diversion section.

[0013] Alternatively, it is planned that the water diversion section is located at the lowest point of the solid-liquid separator.

[0014] Alternatively, it is provided that the water diversion section is designed in the form of a recess, the recess being provided with filter holes, the filter holes facing the deodorization module.

[0015] Alternatively, it is provided that the distance between the bottom surface of the hollowed-out housing and the bottom surface of the wastewater cavity is less than 1 cm.

[0016] Alternatively, it is proposed that the hollowed-out housing be provided with at least a second through-hole on the underside.

[0017] Alternatively, the hollowed-out housing is designed to be cylindrical or as several superimposed cylinders with different radii, wherein the maximum diameter of the hollowed-out housing is 20-32 mm, the minimum diameter of the hollowed-out housing is 12-19 mm, and the height of the hollowed-out housing is 80-134 mm.

[0018] Alternatively, it is provided that the solid-liquid separator is arranged at an angle in the tank body, with the deodorization module being arranged below the lowest position of the solid-liquid separator.

[0019] Alternatively, the hollowed-out housing is designed in a columnar shape, with the cross-section of the hollowed-out housing gradually tapering from bottom to top, or with the cross-section of the lower part of the hollowed-out housing being larger than the cross-section of the upper part.

[0020] Alternatively, it is provided that the deodorizing module is detachably connected to the solid-liquid separating element, the detachable connection method of the deodorizing module comprising a snap-in connection, a magnetic suction connection, a screw connection or a plug connection.

[0021] Alternatively, the wastewater tank may also include an in-position detection module, the in-position detection module being configured to detect whether the deodorization module is installed in position.

[0022] According to an embodiment of the second aspect of the present application, a wastewater tank is provided, wherein the wastewater tank comprises the following components: a tank body with a wastewater cavity and a wastewater inlet channel and a dirt drain opening, each of which is connected to the wastewater cavity; a tank cap that is detachably connected to the tank body in order to open or close the dirt drain opening; a deodorization module located in the wastewater cavity, wherein the deodorization module is column-shaped and provided with a hollowed-out housing, the hollowed-out housing being configured for storing deodorant, the upper part of which extends to the dirt drain opening and the lower part of which extends to the bottom of the wastewater cavity, wherein the deodorization module is detachably connected to the bottom surface of the wastewater cavity, the inner wall of the tank body or the outer wall of the wastewater inlet channel.

[0023] If no solid-liquid separator is installed in the wastewater tank, the deodorization module can be detachably connected to the bottom surface of the wastewater cavity, the inner wall of the tank body, or the outer wall of the wastewater inlet channel.

[0024] The maximum water level of the wastewater cavity is always below the dirt drain opening. The top of the deodorization module extends to the dirt drain opening, so that at least some of its surface is not immersed in wastewater. This reduces the likelihood of the top of the deodorization module being contaminated with wastewater, thus reducing the chance of getting hands dirty when disassembling the deodorization module. Alternatively, the top of the deodorization module is designed to be flush with the level of the dirt drain opening, or to protrude from the dirt drain opening to a certain height.

[0025] According to an embodiment of the third aspect of the present application, a wastewater tank is provided, wherein the wastewater tank comprises the following components: a tank body with a wastewater cavity and a wastewater inlet channel and a dirt drain opening, each of which is connected to the wastewater cavity; a tank cap that is detachably connected to the tank body in order to open or close the dirt drain opening; A deodorizing module located in the wastewater cavity and equipped with a hollowed-out housing, wherein the hollowed-out housing is annular and configured to store deodorant, and wherein the hollowed-out housing is encased outside the wastewater inlet channel. The contact area with the wastewater can be increased by the annular, columnar-shaped hollowed-out housing to improve the deodorizing effect.

[0026] The annular, hollow housing can be positioned close to the outer wall of the wastewater inlet channel. Outside the wastewater inlet channel, for example, an annular, hollow housing is encased, so that a firm connection between the hollow housing and the outer wall of the wastewater inlet channel is achieved through frictional forces. This encasement method facilitates the removal of the deodorization module.

[0027] Alternatively, the wastewater tank is further provided to include the following components: a solid-liquid separator located in the tank body and connected to the tank lid, wherein the outlet of the wastewater inlet channel is arranged above the solid-liquid separator, wherein the dirt exiting through the outlet of the wastewater inlet channel is separated by the solid-liquid separator under the influence of gravity and then flows to the bottom of the wastewater cavity, wherein the solid-liquid separator is configured to filter some of the solid waste in the dirt, wherein the hollowed-out housing is located below the solid-liquid separator and extends along the axial direction of the wastewater inlet channel to the bottom surface of the wastewater cavity.

[0028] According to an embodiment of the fourth aspect of the present application, a cleaning device is provided, wherein the cleaning device comprises a floor brush structure, a body assembly, and a wastewater tank according to one of the embodiments of the first aspect, wherein the body assembly is pivotably connected to the floor brush structure, and wherein the wastewater tank is mounted on the floor brush structure or the body assembly. The technical implications of the embodiments can be found in the preceding embodiments and are not described again here.

The specific meaning of the aforementioned terms in this utility model can be understood by a person skilled in the art according to the specific circumstances.

[0036] The cleaning device according to the embodiments of the present application can be a floor cleaning machine, a sweeping and mopping machine or the like, but is not limited to such.

[0037] To facilitate the description, a floor cleaning machine is illustrated below as an example.

[0038] The floor cleaning machine comprises a floor brush structure 120, a body assembly 110 and a wastewater tank 130, with reference to Fig. 1. During the cleaning process, the user can hold the body assembly 110 in their hand. Swiveling the body assembly 110 drives the movement of the floor brush structure 120, causing the floor brush structure 120 to be in frictional contact with the surface to be cleaned. Surfaces to be cleaned include floors, carpets, walls, tabletops, etc.

[0039] Alternatively, the floor cleaning machine may also have a fresh water tank 140, wherein a cleaning fluid can be supplied to the roller brush through the fresh water tank 140 to infiltrate the roller brush, so that the stain on the surface to be cleaned can be infiltrated by the roller brush during the cleaning process in order to reduce the adhesion of the stain and improve the cleaning effect.

[0040] The wastewater tank 130 serves to collect dirt during the cleaning process, the dirt being generally a solid-liquid mixture.

[0041] The cleaning device may further include a suction device, the suction device serving to provide a vacuum. Under vacuum, the dirt from the surface to be cleaned is sucked into the wastewater tank 130.

[0042] The wastewater tank 130 according to the embodiments of the present application can be a wastewater tank 130 with solid-liquid separation function or a wastewater tank 130 without solid-liquid separation function.

[0043] The wastewater tank 130 without solid-liquid separation comprises a tank body 131, a tank lid 132, and a deodorization module 134. The tank body 131 has a wastewater cavity 1311, a wastewater inlet channel 133, and a dirt drain opening 1314, each of which is connected to the wastewater cavity 1311. The tank lid 132 is detachably connected to the tank body 131 to open or close the dirt drain opening 1314. The deodorization module 134 is located in the wastewater cavity 1311 and is provided with a hollowed-out housing, the hollowed-out housing being used to store deodorant. The cell structure of bacteria can be destroyed by the deodorant, thus killing the bacteria and achieving a deodorizing effect. Deodorization can also be carried out by odor adsorption.

[0044] Since it lacks a solid-liquid separation function, solid waste such as hair and fibrous fabric easily becomes entangled in the dirt on the outer wall of the wastewater inlet channel 133 or the deodorization module 134. To reduce or even prevent entanglement of the outer wall of the wastewater inlet channel 133 or the deodorization module 134, a solid-liquid separation element 1321, based on the structure of the wastewater tank 130 described above, can be added, thus realizing the solid-liquid separation function using the solid-liquid separation element 1321. Therefore, according to the embodiments of the present application, the wastewater tank 130 can also be a wastewater tank 130 with a solid-liquid separation function.

[0045] The following describes the wastewater tank 130 with solid-liquid separation function and the wastewater tank 130 without solid-liquid separation function. Example 1

[0046] In the present embodiment, the wastewater tank 130 with solid-liquid separation function is presented based on the above.

[0047] The wastewater tank 130 according to the present application comprises a tank body 131, a tank lid 132, a solid-liquid separator 1321, and a deodorization module 134, wherein the tank body 131 has a wastewater cavity 1311, a wastewater inlet channel 133, and a dirt drain opening 1314, each of which is connected to the wastewater cavity 1311, wherein the tank lid 132 is detachably connected to the tank body 131 to open or close the dirt drain opening 1314, wherein the solid-liquid separator 1321 is located in the tank body 131 and is connected to the tank lid 132, wherein the outlet 1332 of the wastewater inlet channel 133 is arranged above the solid-liquid separator 1321, and wherein the discharge through the outlet 1332 of the wastewater inlet channel 133 The escaping dirt is separated by the solid-liquid separating element 1321 under the influence of gravity and then flows to the bottom of the wastewater cavity 1311,wherein the solid-liquid separator 1321 is configured to filter a portion of the solid waste in the dirt, wherein the deodorizing module 134 is located in the wastewater cavity 1311 and is provided with a hollowed-out housing, wherein the hollowed-out housing is configured to store deodorant, wherein the deodorizing module 134 is connected to the solid-liquid separator 1321, wherein the hollowed-out housing is arranged below the solid-liquid separator 1321 and extends to the bottom of the wastewater cavity 1311, with reference to , Fig. 2 and Fig. 3.

[0048] By way of example, it is provided that the tank body 131 is cylindrical, it has a side wall 1312 of the substantially ring-shaped tank body, wherein the side walls 1312 of the tank body are enclosed to form a wastewater cavity 1311, wherein the upper opening of the wastewater cavity 1311 is designed as a dirt drain opening 1314, with reference to Fig. 4. The inlet 1331 of the wastewater inlet channel 133 may be located at the bottom of the tank body 131, and the wastewater inlet channel 133 may be located approximately in the middle of the wastewater cavity 1311, but is not limited to this, as shown in Fig. 3 shown.

[0049] The deodorization module 134 is arranged in the wastewater cavity 1311, so that the wastewater can come into contact with the deodorant in the deodorization module 134 through the cavity 1341 of the hollowed-out housing in order to achieve sterilization and deodorization of the wastewater.

[0050] The sterilizing agent may be a silver ion fungicide or an activated carbon deodorant, such as delayed-release silver ion particles and activated carbon particles, but is not limited to these.

[0051] Since the deodorization module 134 is connected to the solid-liquid separator 1321, and the solid-liquid separator 1321 is connected to the tank lid 132, the operator can operate the tank lid 132 to remove the deodorization module 134 from the wastewater cavity 1311, thus enabling the simultaneous disassembly of both the deodorization module 134 and the tank lid 132. The disassembly method is simple and convenient, and there is no need to reach inside the tank body 1311 to assemble and disassemble the deodorization module 134, thereby avoiding extensive hand contamination.

[0052] After the dirt has been separated by the solid-liquid separator 1321, some of the solid waste (including hair and other easily tangled debris) is trapped above the solid-liquid separator 1321. The wastewater, mixed with some of the solid waste, flows through the solid-liquid separator 1321 to the bottom of the wastewater cavity 1311. Because the deodorization module 134 is located below the solid-liquid separator 1321, hair and other easily tangled debris are trapped above the solid-liquid separator 1321, thus greatly reducing the possibility of the deodorization module 134 becoming tangled and clogged by debris.

[0053] In some application scenarios, e.g., when the wastewater in the wastewater tank 130 reaches the maximum water level line or when the wastewater needs to be drained after each self-cleaning cycle, the wastewater tank 130 can first be removed from the cleaning unit. Then the tank lid 132 can be disassembled and the dirt drain opening 1314 opened, allowing wastewater and solid waste to be drained through the dirt drain opening 1314 and the interior of the wastewater cavity 1311 to be cleaned. After the deodorization module 134 has been disassembled along with the tank lid 132, almost all parts of the deodorization module 134 that come into contact with the wastewater can be exposed, allowing even the dirty areas of the deodorization module 134 and the tank lid 132 to be cleaned.

[0054] In some alternative embodiments, the solid-liquid separator 1321 is provided with a water diversion section, wherein the water diversion section is configured to redirect the flow direction of the liquid on the solid-liquid separator 1321, wherein the deodorization module 134 is arranged in the guidance direction of the water diversion section, so that the liquid diverted from the water diversion section flows to the bottom of the wastewater cavity 1311 after passing the deodorization module 134.

[0055] The solid-liquid separator 1321 forms a dominant flow channel for the downward flow of wastewater through the water diversion section; that is, the water diversion section is the main flow channel for the downward flow of wastewater. For example, if wastewater flows downward from several points on the solid-liquid separator 1321, the point with the highest flow rate is the water diversion section. By placing the deodorization module 134 in the same direction of flow as the water diversion section, more wastewater can flow through the deodorization module 134, allowing sufficient contact between the wastewater and the module. The wastewater can thus be pre-sterilized and deodorized before reaching the bottom of the wastewater cavity 1311.In this way, even if the amount of wastewater is small, only part of the lower area of ​​the deodorizing module 134 is in contact with the wastewater, so that the contact with the deodorizing module 134 during wastewater drainage can be used to improve the sterilizing and deodorizing effect.

[0056] In some alternative embodiments, a first through-hole is provided on the top of the hollowed-out housing to receive the liquid diverted from the water diversion section.

[0057] The first through-hole at the top of the hollowed-out housing allows the cavity area of ​​the housing to be increased, thus increasing the likelihood of the wastewater coming into contact with the deodorant. Since the wastewater flows from top to bottom, it can easily be poured directly into the hollowed-out housing through the first through-hole at the top and then flow out, further enhancing the deodorizing effect. Specifically, the wastewater diverted from the water diversion section can at least partially pass through the first through-hole into the interior of the deodorizing module 134 to come into contact with the deodorant within the module. The wastewater, sterilized by the deodorant, can then flow from the cavity 1341 of the hollowed-out housing to the bottom of the wastewater cavity 1311.

[0058] In Fig. Figure 5 illustrates that the cavity 1341 is a multitude of small holes distributed around the circumference of the hollowed-out housing. These cavities 1341, which are circular, can have the same diameter or be large or small. The small holes of the multiple cavities 1341 can be evenly distributed around the side wall of the hollowed-out housing or unevenly distributed. The cavities 1341 located below the deodorizing module 134 may be more numerous, while those above the deodorizing module 134 may be relatively fewer, with reference to Fig. 5.

[0059] It is understood that the hollowing 1341 is not limited to the circular shape shown, but can also be rectangular, triangular, pentagonal, specially shaped or the like.

[0060] The first through-hole at the top of the hollowed-out casing can be a single hole with a larger diameter or several holes with smaller diameters. This first through-hole and the cavity 1341 each communicate with an internal cavity within the hollowed-out casing for storing deodorant.

[0061] In some alternative embodiments, the water diversion section is arranged at the lowest point of the solid-liquid separating element 1321.

[0062] The solid-liquid separator 1321 is designed as an inclined separator plate, wherein a plurality of filter holes are arranged on the surface of the separator plate to allow the filtered wastewater to pass through, with reference to Fig. 3. The lowest position of the solid-liquid separator 1321 is designed as the dominant flow channel for wastewater, specifically the water diversion section. The deodorization module 134 is located below the lowest position of the solid-liquid separator 1321. Most of the filtered wastewater can flow downwards through the deodorization module 134 from the lowest point of the solid-liquid separator 1321, which is advantageous for improving the deodorizing effect.

[0063] In other alternative embodiments, the water diversion section is designed in the form of a recess, wherein the recess is provided with filter holes, the filter holes facing the deodorization module 134.

[0064] The solid-liquid separator 1321 has a through-bore 1323 that is associated with the outlet 1332 of the wastewater inlet channel 133. The recess can be arranged around the through-bore 1323 so that the debris flows sequentially through the outlet 1332 of the wastewater inlet channel 133 and the through-bore 1323, spreading along the through-bore 1323 above the solid-liquid separator 1321. Some of the solid waste is captured because its size is larger than the filter holes, while the solid waste and wastewater, whose size is smaller than the filter holes, flow through the filter holes to the bottom of the wastewater cavity 1311. Due to its lower position and its proximity to the outlet 1332 of the wastewater inlet channel 133, the recess is referred to as a water diversion section.

[0065] In some alternative embodiments, the distance between the bottom surface of the hollowed-out housing and the bottom surface of the wastewater cavity 1311 is less than 1 cm. Since the wastewater rises from the bottom of the wastewater cavity 1311, the wastewater generated by a single cleaning operation may not necessarily reach the maximum water level of the wastewater cavity 1311, and there may be only a small amount of wastewater present. Some of the solid dirt (e.g., sludge) that flows down with the wastewater also accumulates at the bottom of the wastewater cavity 1311, so the bacterial content of the wastewater is relatively higher near the bottom of the wastewater cavity 1311.The distance between the bottom surface of the hollowed-out housing and the bottom surface of the wastewater cavity 1311 is less than 1 cm, so that the bottom of the deodorizing module 134 can come into contact with the bottom of the wastewater cavity 1311 as much as possible. Even if the amount of wastewater is small, it can be kept in contact with the deodorizing module 134 to ensure the sterilizing and deodorizing effect.

[0066] In some alternative embodiments, it is provided that the hollowed-out housing is provided with at least a second through-hole 1342 on the underside.

[0067] The second through-hole 1342 on the underside of the hollowed-out housing allows the cavity area of ​​the housing to be increased, thereby increasing the probability of the wastewater coming into contact with the deodorant and thus improving the deodorizing effect. Specifically, the wastewater diverted from the water diversion section can at least partially pass through the second through-hole 1342 on the underside of the hollowed-out housing into the inner cavity of the deodorizing module 134, allowing it to come into contact with the deodorant within the module. The wastewater, now sterilized by the deodorant, can then flow out through the cavity 1341 of the hollowed-out housing.

[0068] The second through-holes 1342 on the underside of the hollowed-out case can be one or two, three or more. Fig. Figure 5 shows an example of a large number of small diameter second through-holes 1342, which are arranged close together on the underside of the hollowed-out housing.

[0069] In some alternative embodiments, the hollowed-out housing is cylindrical or formed as several stacked cylinders with different radii, wherein the maximum diameter of the hollowed-out housing is 20-32 mm, the minimum diameter is 12-19 mm, and the height of the hollowed-out housing is 80-134 mm. The hollowed-out housing designed in this way can extend to the bottom of the wastewater cavity 1311 to better conform to the wastewater cavity 1311, thereby ensuring the deodorizing effect.

[0070] The in Fig. The deodorizing module 134 shown in Figure 5 comprises, by way of example, two cylinders stacked one on top of the other with different radii. The cylinder in the upper part has a smaller radius of approximately 8 mm, and the cylinder in the lower part has a larger radius of approximately 13 mm. The total length of the hollowed-out housing (which can be understood as the sum of the heights of the upper and lower cylinders) is 111 mm.

[0071] In some alternative embodiments, the solid-liquid separator 1321 is arranged obliquely in the tank body 131, with the deodorization module 134 being arranged below the lowest position of the solid-liquid separator 1321.

[0072] The wastewater flow below the lowest position of the solid-liquid separator 1321 is the largest compared to the wastewater flow below the other positions of the solid-liquid separator 1321. The deodorizing module 134 is located below the lowest position of the solid-liquid separator 1321, allowing more wastewater to come into contact with the deodorant during flow, thus improving the deodorizing effect.

[0073] In some alternative embodiments, the hollowed-out housing is designed in a columnar shape, with the cross-section of the hollowed-out housing gradually tapering from bottom to top (as in Fig. 6 shown), or wherein the cross-section of the lower part of the hollowed-out casing is larger than the cross-section of the upper part (as in Fig. 5 shown).

[0074] In conjunction with the above description, the wastewater rises from the bottom of the wastewater cavity 1311, preferably collects in the bottom of the wastewater cavity 1311, and the bacterial content of the wastewater near the bottom of the wastewater cavity 1311 is relatively higher. Furthermore, it is provided that the cross-section of the hollowed-out housing gradually tapers from bottom to top, or that the cross-section of the lower part of the hollowed-out housing is larger than the cross-section of the upper part, so that the hollowed-out housing has a larger bottom space, allowing the bottom of the hollowed-out housing to be used to store more deodorant, which can effectively improve the deodorizing effect at the bottom of the wastewater cavity 1311.

[0075] For example, the deodorizing module 134 is a deodorizing rod, or the deodorizing module 134 comprises a deodorizing box and a mounting section. A deodorizing box is attached to the underside of the mounting section. The mounting section can generally be strip-shaped to accommodate the role of the deodorizing module 134, which extends to the bottom of the wastewater cavity 1311. A deodorant is mounted in the deodorizing box, and the deodorizing module 134 is mounted to the solid-liquid separator 1321 by a mounting section.

[0076] The deodorizing module 134 does not need to be coated with deodorant at all levels, as the wastewater tank 130 has a maximum wastewater capacity. Sterilizing and deodorizing particles must be present below the level corresponding to this maximum wastewater capacity. This means that the sterilizing agent is distributed at least at the bottom of the deodorizing module 134 near the wastewater cavity 1311.

[0077] If the sterilization and deodorization particles in the inner cavity of the deodorization module 134 are configured proportionally, the sterilization dose at the bottom of the deodorization module 134 can be greater than the sterilization dose above it.

[0078] In some alternative embodiments, the deodorizing module 134 is detachably connected to the solid-liquid separating element 1321, wherein the detachable connection method of the deodorizing module 134 comprises a snap-in connection, a magnetic suction connection, a screw connection or a plug connection.

[0079] The deodorizing module 134 is removable relative to the solid-liquid separator 1321, making it convenient to clean the deodorizing module 134 separately. Alternatively, the deodorizing module 134 can be replaced with a new one if its deodorizing performance no longer meets requirements.

[0080] Furthermore, in other alternative embodiments, a housing cover can also be arranged on the hollowed-out housing, the housing cover serving to open and close the inner cavity of the hollowed-out housing, so that deodorant is stored in the inner cavity. When the deodorizing performance of the deodorizing module 134 no longer meets the requirements, the housing cover is opened to replace the deodorant with new deodorant. In this way, the hollowed-out housing can be reused, thereby reducing operating costs.

[0081] The snap-fit ​​connection comprises, but is not limited to: Snap-fit ​​grooves and snap-fit ​​protrusions are each arranged on the solid-liquid separating element 1321 and the deodorizing module 134, wherein the snap-fit ​​protrusion is inserted into or removed from the snap-fit ​​groove to achieve a removable connection.

[0082] The plug connection includes, but is not limited to: A cannula 1322 is arranged below the solid-liquid separating element 1321, wherein a column-shaped deodorizing module 134 can be inserted into the cannula 1322, with reference to Fig. 3. To improve the reliability of the plug connection, a protrusion 1343 or a spring arm can be arranged at the connection point of the deodorization module 134 with the solid-liquid separator 1321.

[0083] In some alternative embodiments, the wastewater tank 130 further comprises an in-position detection module, wherein the in-position detection module is configured to detect whether the deodorization module 134 is installed in position.

[0084] In-position sensing modules include, but are not limited to, pressure sensors, optoelectronic sensors, visual sensors, or the like.

[0085] The in-position detection module can also be configured to remind the user whether the deodorization module 134 is currently installed and whether it is correctly positioned. It is also possible to estimate the remaining lifespan of the deodorization module 134 based on its duration in position as detected by the in-position detection module and to remind the user to replace it once it has reached the end of its service life. Therefore, the in-position detection module can work in conjunction with other control logic of the cleaning equipment to enhance the intelligence of the wastewater tank 130, thereby improving the user experience. Example 2

[0086] In the present embodiment, the wastewater tank 130 without a solid-liquid separation function is presented based on the foregoing. Embodiment 2 differs from embodiment 1 in that the wastewater tank 130 according to embodiment 2 does not have a solid-liquid separation element 1321, while the other structures can be identical to those in embodiment 1.

[0087] For example, the wastewater tank 130 comprises a tank body 131, a tank lid 132, and a deodorization module 134, wherein the tank body 131 has a wastewater cavity 1311, a wastewater inlet channel 133, and a dirt drain opening 1314, each of which is connected to the wastewater cavity 1311, wherein the tank lid 132 is detachably connected to the tank body 131 to open or close the dirt drain opening 1314, wherein the deodorization module 134 is located in the wastewater cavity 1311, wherein the deodorization module 134 is columnar in form and is provided with a hollowed-out housing, wherein the hollowed-out housing is configured to store deodorant, and wherein its upper part extends to the dirt drain opening 1314 and its lower part extends to the bottom of the wastewater cavity 1311.

[0088] In some embodiments, the deodorization module 134 is provided to be detachably connected to the bottom surface of the wastewater cavity 1311, the inner wall (as in Fig. 7 shown) of the tank body 131 or the outer wall of the wastewater inlet channel 133.

[0089] In some alternative embodiments, it is provided that the deodorizing module 134 can also be detachably connected to the tank lid 132.

[0090] The maximum water level of the wastewater cavity 1311 is always below the dirt drain opening 1314. The top of the deodorization module 134 extends to the dirt drain opening 1314, so that the top of the deodorization module 134 is not immersed in wastewater, at least in some areas. This means that the probability of the top of the deodorization module 134 being contaminated with wastewater, at least in some areas, is reduced, thus reducing the likelihood of getting your hands dirty when disassembling the deodorization module 134. The deodorization module 134 is detachably connected to the bottom surface of the wastewater cavity 1311, so that the deodorization module 134 can be positioned anywhere between the outer wall of the wastewater inlet channel 133 and the inner wall of the tank body 131.

[0091] The inner wall of tank body 131 refers to the one in Fig. 4 side wall 1312 of the tank body shown, wherein the side wall 1312 of the tank body is enclosed to form a wastewater cavity 1311, as in Fig. 4 shown. The deodorization module 134 is detachably connected to the side wall 1312 of the tank body, as shown in Fig. Figure 7 shows that the deodorization module 134 is detachably connected to the inner wall of the wastewater cavity 1311. This not only makes disassembly of the deodorization module 134 convenient, but also allows the inner wall of the tank body 131 to be used to provide support for the deodorization module 134, thus improving the reliability of its assembly within the wastewater cavity 1311. The deodorization module 134 is detachably connected to the inner wall of the wastewater cavity 1311, and one of its side walls fits almost flush against the inner wall of the tank body 131, preventing solid waste from easily becoming trapped on the deodorization module 134.

[0092] The deodorization module 134 is detachably connected to the outer wall of the wastewater inlet channel 133, so that the outer wall of the wastewater inlet channel 133 can also provide support for the deodorization module 134 to improve the reliability of the assembly of the deodorization module 134 within the wastewater cavity 1311, as shown in Fig. 9 shown.

[0093] Alternatively, the top of the deodorization module 134 is provided to be flush with the height of the dirt drain opening 1314, or that the top of the deodorization module 134 protrudes from the dirt drain opening 1314 to a height as shown in Fig. Figure 8 shows that this further reduces the possibility of the top of the deodorizing module 134 becoming contaminated with dirt, thus making disassembly of the deodorizing module 134 even easier. When the top of the deodorizing module 134 protrudes above the dirt drain opening 1314, the protruding part of the deodorizing module 134 can be grasped by hand to disassemble the module, making disassembly simple and convenient while further reducing the possibility of hand contamination.

[0094] The upper edge of the inner wall, where the wastewater cavity 1311 is formed, is enclosed to create a dirt drain opening 1314. The top of the deodorization module 134 is flush with the height of the dirt drain opening 1314, which means that the top of the deodorization module 134 is approximately flush with the upper edge 1313 of the side wall 1312 of the tank body (as shown in Fig. 4 shown).

[0095] In some embodiments, based on the foregoing embodiments, it is provided that the hollowed-out housing can further be designed in an annular column shape, wherein the annular column-shaped hollowed-out housing is configured for storing deodorant, wherein the hollowed-out housing is encased outside the wastewater inlet channel 133, as shown in Fig. 9 shown.

[0096] The annular, hollow housing can be positioned close to the outer wall of the wastewater inlet channel 133. Outside the wastewater inlet channel 133, for example, an annular, hollow housing is encased, so that a firm connection between the hollow housing and the outer wall of the wastewater inlet channel 133 is achieved through frictional forces, as shown in Fig. Figure 9 shows this encasing method. This method facilitates the disassembly of the deodorization module 134.

[0097] In further alternative embodiments, it is provided that a gap may exist between the ring-column-shaped hollowed-out housing and the outer wall of the wastewater inlet channel 133.

[0098] It is understood that some embodiments of embodiment 1 and embodiment 2 can be combined to form a new embodiment, provided there is no contradiction.

[0099] For example, based on embodiment 2, the wastewater tank 130 further comprises a solid-liquid separator 1321, wherein the solid-liquid separator 1321 is located in the tank body 131, wherein the outlet 1332 of the wastewater inlet channel 133 is arranged above the solid-liquid separator 1321, wherein the dirt exiting through the outlet 1332 of the wastewater inlet channel 133 is separated by the solid-liquid separator 1321 under the influence of gravity and then flows to the bottom of the wastewater cavity 1311, wherein the solid-liquid separator 1321 is configured to filter out a portion of the solid waste in the dirt, wherein the hollowed-out housing is arranged below the solid-liquid separator 1321 and extends along the axial direction of the wastewater inlet channel 133 extends to the floor surface of the wastewater cavity 1311.

[0100] As a further example, based on the above, the deodorization module 134 of the wastewater tank 130 with solid-liquid separation function can also be encased outside the wastewater inlet channel 133, whereby the deodorization module 134 can also be snapped into place on the bottom of the wastewater cavity 1311. Furthermore, the deodorization module 134 can also be designed in the form of an annular column. Example 3

[0101] The cleaning device according to the present embodiment comprises a floor brush structure 120, a body assembly 110 and a wastewater tank 130 according to one of the preceding embodiments, wherein the body assembly 110 is pivotably connected to the floor brush structure 120, and wherein the wastewater tank 130 is mounted on the floor brush structure 120 or the body assembly 110.

[0102] In some embodiments, the wastewater tank 130 is detachably mounted on the body assembly 110, with reference to Fig. 1. In this case, the body assembly 110 supports the weight of the wastewater tank 130, with the body assembly 110 being heavier. In other embodiments, the wastewater tank 130 is detachably mounted on the floor brush structure 120. The weight of the wastewater tank 130 is supported by the floor brush structure 120, thus making the cleaning process more labor-efficient.

[0103] The cleaning device may further include a suction device, the suction device serving to provide a vacuum. The dirt on the roller brush is sucked into the wastewater tank 130.
