Description

Technical Field

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

[0002] With the development of science and technology and the improvement of living standards, household cleaning equipment has become more and more popular, reducing the burden of human housework.

[0003] In the related technology, a floor scrubber is an example of a cleaning device. The floor scrubber performs wet cleaning on the surface to be cleaned, and the dirt generated by the cleaning is collected in a sewage tank. The dirt is easy to breed bacteria and cause the sewage tank to stink, affecting the user experience. Currently, there is a method of removing the odor by placing a deodorizing device in the sewage tank, but the deodorizing device is either fixed in the sewage tank and cannot be disassembled, or it is inconvenient to disassemble, resulting in a poor user experience. Utility Model Content

[0004] In view of the above problems, the embodiments of the present application provide a sewage tank and a cleaning device, 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.

[0005] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:

[0006] A first aspect of the present application provides a sewage tank, the sewage tank comprising:

[0007] The box body has a sewage cavity, and a sewage inlet channel and a sewage dumping port respectively connected to the sewage cavity;

[0008] A box cover, detachably connected to the box body to open or close the dirt dumping opening;

[0009] A solid-liquid separator is located in the box body and connected to the box cover. The solid-liquid separator can be disassembled and assembled together with the box cover. The outlet of the sewage inlet channel is located above the solid-liquid separator. The dirt 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 some solid garbage in the dirt.

[0010] The deodorizing module is located in the sewage cavity and is provided with a hollow shell for storing deodorant. The deodorizing module is connected to the solid-liquid separator. The hollow shell is located below the solid-liquid separator and extends toward the bottom of the sewage cavity.

[0011] The deodorizing module is located in the sewage cavity. The sewage can come into contact with the deodorant in the deodorizing module through the hollowing of the hollow shell. The deodorant can destroy the cell structure of bacteria, kill bacteria, and achieve a deodorizing effect. It can also deodorize by odor absorption.

[0012] The bactericide may be a silver ion bactericide or an activated carbon deodorant, such as silver ion slow-release particles or activated carbon particles, but is not limited thereto.

[0013] Since the deodorizing module is connected to the solid-liquid separator, which is in turn connected to the box cover, the operator can operate the box cover to take the deodorizing module out of the sewage chamber, thereby achieving simultaneous disassembly of the deodorizing module and the box cover. The disassembly method is simple and convenient, and there is no need to reach into the box to disassemble and assemble the deodorizing module, thus avoiding the situation where a large area of ​​hands are soiled.

[0014] After the dirt is separated by the solid-liquid separator, some solid garbage (including hair and other garbage that are easy to get tangled) is intercepted on the top of the solid-liquid separator, and the sewage mixed with some solid garbage passes through the solid-liquid separator and flows to the bottom of the sewage chamber. Since the deodorization module is located below the solid-liquid separator, hair and other garbage that are easy to get tangled are intercepted on the top by the solid-liquid separator, and the possibility of the deodorization module being entangled and blocked by garbage is greatly reduced.

[0015] In some application scenarios, for example, when the sewage in the sewage tank reaches the maximum water level, or when the sewage needs to be dumped after each self-cleaning, the sewage tank can be removed from the cleaning device first, and then the tank cover can be removed to open the dirty dumping port, and the sewage and solid garbage can be dumped through the dirty dumping port and the inside of the sewage cavity can be cleaned. After the deodorization module is removed with the tank cover, the part of the deodorization module that contacts the sewage can be almost completely exposed, and the dirtier parts of the deodorization module and the tank cover can also be cleaned.

[0016] Optionally, the solid-liquid separator is provided with a water diversion part, 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 diversion part, so that the liquid drained by the water diversion part flows to the bottom of the sewage chamber after passing through the deodorization module.

[0017] Optionally, a first through hole is provided on the top surface of the hollow shell to receive the liquid drained by the water diversion part.

[0024] Optionally, the hollow shell is columnar; the cross section of the hollow shell gradually shrinks from bottom to top, or the cross section of the bottom of the hollow shell is larger than the cross section of the top.

[0025] Optionally, the deodorizing module is detachably connected to the solid-liquid separator, and the detachable connection method of the deodorizing module includes a snap connection, a magnetic connection, a threaded connection or a plug-in connection.

[0026] Optionally, the sewage tank further comprises: an in-situ detection module, and the in-situ detection module is used to detect whether the deodorization module is installed in place.

[0027] A second aspect of the present application provides a sewage tank, the sewage tank comprising:

[0028] The box body has a sewage cavity, and a sewage inlet channel and a sewage dumping port respectively connected to the sewage cavity;

[0029] A box cover, detachably connected to the box body to open or close the dirt dumping opening;

[0030] A deodorizing module is located in the sewage cavity. The deodorizing module is columnar and is provided with a hollow shell. The hollow shell is used to store deodorant. The top of the hollow shell extends to the dirty dumping port, and the bottom of the hollow shell extends to the bottom of the sewage cavity. The deodorizing module is detachably connected to the bottom surface of the sewage cavity, the inner wall of the box body, or the outer wall of the sewage inlet channel.

[0031] When the sewage tank is not provided with a solid-liquid separation component, the deodorization module can be detachably connected to the bottom surface of the sewage cavity, the inner wall of the box body or the outer wall of the sewage inlet channel.

[0032] The maximum water level of the sewage chamber is below the dirty dumping port, and the top of the deodorizing module extends to the dirty dumping port so that at least a portion of the top of the deodorizing module will not be immersed in the sewage, that is, the possibility of at least a portion of the top of the deodorizing module being contaminated by sewage is reduced, which can reduce the possibility of dirty hands when removing the deodorizing module.

[0052] In order to make the technical solutions and beneficial effects of the utility model more obvious and easy to understand, the following is a detailed description by listing specific embodiments. The drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application belongs.

They are only for the convenience of simplifying the description of the present invention, and do not indicate that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and should not be understood as a limitation on the present invention.

[0054] In the present invention, the terms "first" and "second" are used only for the purpose of clarity of description and cannot be understood as the relative importance of the indicated features or the number of the indicated technical features. Therefore, the features defined as "first" and "second" can expressly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc.

[0055] In the present invention, unless otherwise clearly defined, the terms "install", "connect", "connect", "fix", "set", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] The cleaning device in the embodiment of the present application may be a floor scrubber, a sweeper and mop machine, etc., but is not limited thereto.

[0057] For the convenience of description, a floor scrubber is used as an example for explanation below.

[0058] refer to Figure 1 As shown, the floor scrubber includes a floor brush structure 120, a body assembly 110 and a sewage tank 130. During the cleaning process, the user can hold the body assembly 110 and swing the body assembly 110 to drive the floor brush structure 120 to move forward, so that the floor brush structure 120 is in friction contact with the surface to be cleaned, so as to clean the surface to be cleaned. The surface to be cleaned includes the floor, carpet, wall, desktop, etc.

[0059] Optionally, the floor scrubber may further include a clean water tank 140, which may provide cleaning liquid to the roller brush to soak the roller brush, so that the roller brush may soak the stains on the surface to be cleaned during the cleaning process, thereby reducing the adhesion of the stains and improving the cleaning effect.

[0060] The sewage tank 130 is used to collect dirt from the cleaning process, and the dirt is generally a mixture of solid and liquid.

[0061] The cleaning device may further include a suction device, which provides negative pressure. Under the effect of the negative pressure, dirt on the surface to be cleaned is sucked into the sewage tank 130 .

[0062] The sewage tank 130 in the embodiment of the present application may be a sewage tank 130 with a solid-liquid separation function, or may be a sewage tank 130 without a solid-liquid separation function.

[0063] The sewage tank 130 without solid-liquid separation function includes: a box body 131, a box cover 132 and a deodorization module 134. The box body 131 has a sewage cavity 1311, and a sewage inlet channel 133 and a dirty dumping port 1314 respectively connected to the sewage cavity 1311; the box cover 132 is detachably connected to the box body 131 to open or close the dirty dumping port 1314; the deodorization module 134 is located in the sewage cavity 1311, and is provided with a hollow shell, and a deodorant is contained in the hollow shell. The deodorant can destroy the cell structure of bacteria, kill bacteria, and have a deodorizing effect. Alternatively, the deodorant deodorizes by odor absorption.

[0064] Since there is no solid-liquid separation function, solid waste such as hair and fiber fabrics in the dirt is easily entangled on the outer wall of the sewage inlet channel 133 or the deodorization module 134. In order to reduce or even avoid the outer wall of the sewage inlet channel 133 or the deodorization module 134 from being entangled, a solid-liquid separation member 1321 can be added on the basis of the aforementioned sewage tank 130 structure, and the solid-liquid separation function is realized by using the solid-liquid separation member 1321. Therefore, the sewage tank 130 of the embodiment of the present application can also be a sewage tank 130 with a solid-liquid separation function.

[0065] The sewage tank 130 with a solid-liquid separation function and the sewage tank 130 without a solid-liquid separation function are respectively introduced below. Example 1

[0066] This embodiment introduces a sewage tank 130 with a solid-liquid separation function based on the above.

[0067] See also Figure 2 and Figure 3As shown, the sewage tank 130 of the present application includes: a box body 131, a box cover 132, a solid-liquid separator 1321 and a deodorizing module 134, wherein the box body 131 has a sewage cavity 1311, and a sewage inlet channel 133 and a dirty dumping port 1314 respectively connected to the sewage cavity 1311; the box cover 132 is detachably connected to the box body 131 to open or close the dirty dumping port 1314; the solid-liquid separator 1321 is located in the box body 131 and is connected to the box cover 132, and the outlet 1332 of the sewage inlet channel 133 is located at the solid-liquid separator 1321. Above the 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 then flows to the bottom of the sewage chamber 1311. The solid-liquid separator 1321 is used to filter some solid garbage in the dirt; the deodorization module 134 is located in the sewage chamber 1311, which is provided with a hollow shell, and the hollow shell is used to store deodorant. The deodorization module 134 is connected to the solid-liquid separator 1321, and the hollow shell is located below the solid-liquid separator 1321 and extends toward the bottom of the sewage chamber 1311.

[0068] For example, see Figure 4 The box body 131 is cylindrical and includes a substantially annular box body side wall 1312. The box body side wall 1312 encloses a sewage cavity 1311. The top opening of the sewage cavity 1311 is a dirty dumping port 1314. Figure 3 As shown, the inlet 1331 of the sewage inlet channel 133 may be located at the bottom of the box body 131, and the sewage inlet channel 133 may be located approximately in the middle of the sewage chamber 1311, but is not limited thereto.

[0069] The deodorizing module 134 is located in the sewage cavity 1311 , and the sewage can come into contact with the deodorant in the deodorizing module 134 through the hollow 1341 of the hollow shell, so as to achieve a sterilizing and deodorizing effect on the sewage.

[0070] The bactericide may be a silver ion bactericide or an activated carbon deodorant, such as silver ion slow-release particles or activated carbon particles, but is not limited thereto.

[0071] Since the deodorizing module 134 is connected to the solid-liquid separator 1321, and the solid-liquid separator 1321 is connected to the box cover 132, the operator can operate the box cover 132 to take out the deodorizing module 134 from the sewage chamber 1311, so as to realize the synchronous disassembly of the deodorizing module 134 and the box cover 132, and the disassembly method is simple and convenient. There is no need to reach into the box body 131 to disassemble the deodorizing module 134, thus avoiding the situation of dirtying a large area of ​​hands.

[0072] After the dirt is separated by the solid-liquid separator 1321, some solid garbage (including hair and other garbage that are easy to get entangled) is intercepted above the solid-liquid separator 1321, and the sewage mixed with some solid garbage passes through the solid-liquid separator 1321 and flows to the bottom of the sewage chamber 1311. Since the deodorization module 134 is located below the solid-liquid separator 1321, hair and other garbage that are easy to get entangled are intercepted above by the solid-liquid separator 1321, and the possibility of the deodorization module 134 being entangled by garbage is greatly reduced.

[0073] In some application scenarios, for example, when the sewage in the sewage tank 130 reaches the maximum water level, or when the sewage needs to be dumped after each self-cleaning, the sewage tank 130 can be removed from the cleaning device first, and then the box cover 132 can be removed to open the dirty dumping port 1314, and the sewage and solid garbage can be dumped through the dirty dumping port 1314 to clean the inside of the sewage cavity 1311. After the deodorization module 134 is removed along with the box cover 132, the part of the deodorization module 134 that contacts the sewage can be almost completely exposed, and the dirtier parts of the deodorization module 134 and the box cover 132 can also be cleaned.

[0074] In some optional embodiments, the solid-liquid separator 1321 is provided with a water diversion portion, 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 diversion portion, so that the liquid drained by the water diversion portion flows to the bottom of the sewage chamber 1311 after passing through the deodorization module 134.

[0075] The solid-liquid separator 1321 forms a dominant flow channel for the sewage to flow downward through the water diversion part. In other words, the water diversion part is the main flow channel for the sewage to flow downward. For example: if the sewage flows downward from multiple positions of the solid-liquid separator 1321, the position with the largest flow is the water diversion part. Placing the deodorization module 134 in the guiding direction of the water diversion part can allow more sewage to flow through the deodorization module 134, and the sewage can fully contact the deodorization module 134. The sewage can undergo preliminary sterilization and deodorization before falling to the bottom of the sewage chamber 1311. In this way, even if the amount of sewage is small, and only part of the bottom area of ​​the deodorization module 134 contacts the sewage, the contact between the sewage and the deodorization module 134 during the process of sewage flowing down can be used to improve the sterilization and deodorization effect.

[0076] In some optional embodiments, a first through hole is provided on the top surface of the hollow shell to receive the liquid drained by the water diversion part.

[0077] The first through hole on the top surface of the hollow shell can increase the hollow area of ​​the hollow shell, increase the contact probability between the sewage and the deodorant, and because the sewage flows from top to bottom, it can easily be directly poured into the hollow shell through the first through hole on the top and then flow out, further improving the deodorization effect. Specifically, the sewage drained by the water diversion part can at least partially enter the deodorization module 134 through the first through hole and contact the deodorant in the deodorization module 134. The sewage sterilized by the deodorant can flow from the hollow 1341 of the hollow shell to the bottom of the sewage cavity 1311.

[0078] Figure 5 As shown in the figure, the hollowing 1341 is a plurality of small holes distributed around the hollow shell. The diameters of the hollowing 1341 formed as circular holes can be equal or can be large or small. The plurality of hollowing holes 1341 can be evenly distributed on the side wall of the hollow shell or can be unevenly distributed. Figure 5 As shown, the number of small holes in the hollow 1341 below the deodorizing module 134 may be more, while the number of small holes above the deodorizing module 134 may be relatively less.

[0079] It is understandable that the hollowing 1341 is not limited to the circle shown in the figure, but can also be a rectangle, a triangle, a pentagon, an irregular shape, etc.

[0080] The first through hole on the top surface of the hollow shell can be a hole with a larger diameter or multiple holes with smaller diameters. The first through hole and the hollow 1341 are both connected to the inner cavity of the hollow shell for storing the deodorant.

[0081] In some optional embodiments, the water guide portion is located at the lowest point of the solid-liquid separation element 1321 .

[0082] See also Figure 3 The solid-liquid separator 1321 is an inclined separator plate, and a plurality of filter holes are provided on the surface of the separator plate to allow the filtered sewage to pass through. The lowest position of the solid-liquid separator 1321 is the dominant flow channel of the sewage, which is the water diversion part. The deodorization module 134 is located below the lowest position of the solid-liquid separator 1321. Most of the filtered sewage can flow downward through the deodorization module 134 through the lowest point of the solid-liquid separator 1321, which is conducive to improving the deodorization effect.

[0083] In some other optional implementations, the water guide portion is provided in the form of a groove, and the groove is provided with a filter hole, and the filter hole faces the deodorization module 134.

[0084] The solid-liquid separator 1321 has a through hole 1323 that docks with the outlet 1332 of the sewage inlet channel 133, and the groove can be arranged around the through hole 1323. After the dirt flows out through the outlet 1332 of the sewage inlet channel 133 and the through hole 1323 in turn, it spreads around the through hole 1323 above the solid-liquid separator 1321. Some solid waste is intercepted because its size is larger than the filter hole, while solid waste and sewage with a size smaller than the filter hole pass through the filter hole and flow to the bottom of the sewage chamber 1311. The groove is called a water guide part because it is located at a lower position and is closer to the outlet 1332 of the sewage inlet channel 133.

[0085] In some optional embodiments, the distance between the bottom surface of the hollow shell and the bottom surface of the sewage chamber 1311 is less than 1 cm. Since the sewage rises from the bottom of the sewage chamber 1311, the sewage generated by a single cleaning operation may not reach the maximum water level of the sewage chamber 1311, and there may be only a small amount of sewage. In addition, some solid dirt (such as sludge) that flows down with the sewage will also accumulate at the bottom of the sewage chamber 1311, so the sewage bacteria content near the bottom of the sewage chamber 1311 is relatively higher. The distance between the bottom surface of the hollow shell and the bottom surface of the sewage chamber 1311 is less than 1 cm, so that the bottom of the deodorization module 134 can be in contact with the bottom of the sewage chamber 1311 as much as possible, and even when the amount of sewage is small, the sewage can be kept in contact with the deodorization module 134 to ensure the sterilization and deodorization effect.

[0086] In some optional embodiments, the hollow shell is provided with a second through hole 1342 at least at the bottom.

[0087] The second through hole 1342 at the bottom of the hollow shell can increase the hollow area of ​​the hollow shell, increase the contact probability between the sewage and the deodorant, and improve the deodorization effect. Specifically, the sewage drained by the water diversion part can at least partially enter the inner cavity of the deodorization module 134 through the second through hole 1342 at the bottom of the hollow shell, and contact the deodorant in the deodorization module 134. The sewage sterilized by the deodorant can flow out from the hollow 1341 of the hollow shell.

[0088] The number of the second through hole 1342 at the bottom of the hollow shell can be one, two, three or more. Figure 5 It is exemplarily shown that the bottom of the hollow shell is densely covered with a plurality of second through holes 1342 with small diameters.

[0089] In some optional embodiments, the hollow shell is cylindrical or multiple cylinders with different radii are stacked, the maximum diameter of the hollow shell is 20-32 mm, the minimum diameter of the hollow shell is 12-19 mm, and the height of the hollow shell is 80-134 mm. This type of hollow shell can extend to the bottom of the sewage cavity 1311, better fit the sewage cavity 1311, and ensure the deodorization effect.

[0090] For example, Figure 5 The deodorizing module 134 shown is composed of two cylinders with different radii stacked together, wherein the upper cylinder has a smaller radius of about 8 mm, while the lower cylinder has a larger radius of 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.

[0091] In some optional embodiments, the solid-liquid separator 1321 is tiltedly disposed in the box body 131 , and the deodorization module 134 is located below the lowest position of the solid-liquid separator 1321 .

[0092] Compared with other positions below the solid-liquid separator 1321, the sewage flow rate below the lowest position of the solid-liquid separator 1321 is the largest. The deodorization module 134 is located below the lowest position of the solid-liquid separator 1321, which can allow more sewage to contact the deodorant during the falling process, thereby improving the deodorization effect.

[0093] In some optional embodiments, the hollow shell is columnar; the cross section of the hollow shell gradually shrinks from bottom to top (such as Figure 6 ), or, the cross-section of the bottom of the hollow shell is larger than the cross-section of the top thereof (as shown in Figure 5 as shown).

[0094] Combined with the above description, sewage rises from the bottom of the sewage chamber 1311, and the bottom of the sewage chamber 1311 preferentially collects sewage, and the sewage bacteria content near the bottom of the sewage chamber 1311 is relatively higher. The cross section of the hollow shell gradually shrinks from bottom to top, or the cross section of the bottom of the hollow shell is larger than the cross section of the top, which makes the hollow shell have a larger bottom space, and then the bottom of the hollow shell can store more deodorant, which can effectively improve the deodorization effect on the bottom of the sewage chamber 1311.

[0095] Exemplarily, the deodorizing module 134 is a deodorizing stick, or the deodorizing module 134 includes a deodorizing box and a mounting portion, the deodorizing box is connected to the bottom of the mounting portion, and the mounting portion can be roughly long and narrow to meet the function of extending the deodorizing module 134 to the bottom of the sewage chamber 1311. A deodorant is installed in the deodorizing box, and the deodorizing module 134 is installed on the solid-liquid separator 1321 through the mounting portion.

[0096] The deodorizing module 134 does not need to have deodorant at all its heights, because the sewage tank 130 has a maximum sewage capacity, and there must be sterilizing and deodorizing particles below the height corresponding to the maximum sewage capacity. In other words, the deodorant is distributed at least at the bottom of the deodorizing module 134 close to the sewage chamber 1311.

[0097] When the sterilizing and deodorizing particles in the inner cavity of the deodorizing module 134 are configured in proportion, the sterilizing dosage at the bottom of the deodorizing module 134 may be greater than the sterilizing dosage above it.

[0098] In some optional embodiments, the deodorizing module 134 is detachably connected to the solid-liquid separator 1321 , and the detachable connection method of the deodorizing module 134 includes snap connection, magnetic connection, threaded connection or plug-in connection.

[0099] The deodorizing module 134 is detachable relative to the solid-liquid separator 1321 , so that the deodorizing module 134 can be easily cleaned separately, or replaced with a new deodorizing module 134 when the deodorizing efficiency of the deodorizing module 134 fails to meet the requirements.

[0100] In addition, in other optional embodiments, a shell cover can be provided on the hollow shell, and the shell cover can open or close the inner cavity of the hollow shell, and the deodorant is stored in the inner cavity. When the deodorizing efficiency of the deodorizing module 134 cannot meet the requirements, the shell cover is opened and a new deodorant is replaced, so that the hollow shell can be reused, saving the use cost.

[0101] The snap connection includes but is not limited to: a snap connection groove and a snap connection protrusion are respectively provided on the solid-liquid separator 1321 and the deodorization module 134, and the snap connection protrusion is inserted into the snap connection groove, or taken out from the snap connection groove to achieve a detachable connection.

[0102] Plug-in connections include but are not limited to: Figure 3 As shown, a plug 1322 is provided below the solid-liquid separator 1321 , and the columnar deodorizing module 134 can be inserted into the plug 1322 . To improve the reliability of the plug-in connection, a protrusion 1343 or an elastic arm can be provided at the connection position between the deodorizing module 134 and the solid-liquid separator 1321 .

[0103] In some optional embodiments, the sewage tank 130 further includes: an on-site detection module, which is used to detect whether the deodorization module 134 is installed in place.

[0104] The in-situ detection module includes but is not limited to a pressure sensor, a photoelectric sensor or a visual sensor.

[0105] The in-situ detection module can be used to remind the user whether the deodorization module 134 is currently installed and whether the deodorization module 134 is installed in place. The service life of the deodorization module 134 can also be evaluated according to the in-situ time of the deodorization module 134 detected by the in-situ detection module, and the user can be reminded to replace the deodorization module 134 with a new one after the deodorization module 134 reaches its service life. Therefore, the in-situ detection module can cooperate with other control logics of the cleaning equipment to improve the intelligence of the sewage tank 130 and improve the user experience. Example 2

[0106] This embodiment introduces a sewage tank 130 without solid-liquid separation function based on the above. The difference between the embodiment 2 and the embodiment 1 is that the sewage tank 130 of the embodiment 2 does not have a solid-liquid separation member 1321, and the rest of the structure is the same as the embodiment 1.

[0107] For example, the sewage tank 130 includes a tank body 131, a tank cover 132 and a deodorizing module 134. The tank body 131 has a sewage cavity 1311, and a sewage inlet channel 133 and a dirty dumping port 1314 respectively connected to the sewage cavity 1311; the tank cover 132 is detachably connected to the tank body 131 to open or close the dirty dumping port 1314; the deodorizing module 134 is located in the sewage cavity 1311, and the deodorizing module 134 is columnar and is provided with a hollow shell for storing deodorant, with its top extending to the dirty dumping port 1314 and its bottom extending to the bottom of the sewage cavity 1311.

[0108] In some embodiments, the deodorizing module 134 can be detachably connected to the bottom surface of the sewage chamber 1311 and the inner wall of the box body 131 (such as Figure 7 As shown) or the outer side wall of the sewage inlet channel 133.

[0109] In some optional embodiments, the deodorization module 134 may also be detachably connected to the box cover 132 .

[0110] The maximum water level of the sewage chamber 1311 is below the dirty dumping port 1314, and the top of the deodorizing module 134 extends to the dirty dumping port 1314 so that at least a portion of the top of the deodorizing module 134 will not be immersed in the sewage, that is, the possibility of at least a portion of the top of the deodorizing module 134 being contaminated by sewage is reduced, which can reduce the possibility of dirty hands when removing the deodorizing module 134. When the deodorizing module 134 is detachably connected to the bottom surface of the sewage chamber 1311, the deodorizing module 134 can be located at any position between the outer wall of the sewage inlet channel 133 and the inner wall of the box body 131.

[0111] like Figure 4 As shown, the inner wall of the box body 131 is Figure 4 The side walls 1312 of the box body are shown, and the side walls 1312 of the box body enclose a sewage chamber 1311. Figure 7 As shown, the deodorizing module 134 is detachably connected to the side wall 1312 of the box body. The deodorizing module 134 is detachably connected to the inner wall of the sewage chamber 1311, which not only facilitates the disassembly of the deodorizing module 134, but also can use the inner side wall of the box body 131 to provide support for the deodorizing module 134, thereby improving the reliability of the deodorizing module 134 installed in the sewage chamber 1311. Moreover, the deodorizing module 134 is detachably connected to the inner wall of the sewage chamber 1311, and one side wall of the deodorizing module 134 is almost in contact with the inner side wall of the box body 131, so that the solid garbage in the dirt is not easy to be entangled on the deodorizing module 134.

[0112] like Fig. 9 As shown, when the deodorizing 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 deodorizing module 134 , thereby improving the reliability of the deodorizing module 134 installed in the sewage chamber 1311 .

[0113] Optionally, the top of the deodorizing module 134 is flush with the height of the dirty dump port 1314, or Figure 8 As shown, the top of the deodorizing module 134 protrudes out of the dirt dumping port 1314. In this way, the possibility of the top of the deodorizing module 134 being contaminated by dirt can be further reduced, and the removal of the deodorizing module 134 is further facilitated. If the top of the deodorizing module 134 protrudes out of the dirt dumping port 1314, the deodorizing module 134 can be removed by holding the protruding part of the deodorizing module 134, which is simple and convenient to remove, and further reduces the possibility of dirty hands.

[0114] The top edge of the inner wall forming the sewage chamber 1311 encloses the 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 flush with the top edge 1313 ( Figure 4 as shown).

[0115] In some embodiments, based on the above embodiments, Fig. 9 As shown, the hollow shell can also be in the shape of a ring column, and the ring column-shaped hollow shell is used to store deodorant, and the hollow shell is sleeved outside the sewage inlet channel 133.

[0116] like Fig. 9 The hollow shell of the ring column shape can be set close to the outer wall of the sewage inlet channel 133, for example, the hollow shell of the ring column shape is sleeved outside the sewage inlet channel 133, and the hollow shell is fixedly connected with the outer wall of the sewage inlet channel 133 through the friction between the hollow shell and the outer wall of the sewage inlet channel 133. This sleeve connection method facilitates the disassembly of the deodorization module 134.

[0117] In some other optional embodiments, there may be a gap between the annular column-shaped hollow shell and the outer wall of the sewage inlet channel 133 .

[0118] It is understandable that, under the premise that there is no contradiction, some implementations of Embodiment 1 and Embodiment 2 can be combined to form a new embodiment.

[0119] For example: Based on Example 2, the sewage tank 130 also includes: a solid-liquid separator 1321, the solid-liquid separator 1321 is located in the box body 131, and 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 solid garbage 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.

[0120] For another example, based on the above, the deodorizing module 134 of the sewage tank 130 with solid-liquid separation function can also be sleeved outside the sewage inlet channel 133, and the deodorizing module 134 can also be clamped at the bottom of the sewage chamber 1311. In addition, the deodorizing module 134 can also be annular. Example 3

[0122] refer to Figure 1 As shown, in some implementations, the sewage tank 130 is detachably mounted on the body assembly 110. In this case, the body assembly 110 bears the weight of the sewage tank 130, and the body assembly 110 is heavy. In other implementations, the sewage tank 130 is detachably mounted on the floor brush structure 120, and the floor brush structure 120 bears the weight of the sewage tank 130, so that the cleaning process is more labor-saving.

[0123] The cleaning device may further include a suction device, which provides negative pressure to suck dirt on the roller brush into the sewage tank 130 .
