[0053] 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.

[0054] For the convenience of description, a floor scrubber is used as an example for explanation below.

[0055] 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.

[0056] 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.

[0057] The sewage tank 130 is used to collect dirt from the cleaning process, and the dirt is generally a mixture of solid and liquid.

[0058] 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 .

[0059] 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.

[0060] See also Figure 2 and Figure 3 As shown, 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.

[0061] 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.

[0062] 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

[0063] This embodiment introduces a sewage tank 130 with a solid-liquid separation function based on the above.

[0064] See also Figure 2 and Figure 3 As 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 deodorization 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 sewage inlet channel outlet 1332 is located in the solid-liquid Above the separator 1321, the dirt output from the sewage inlet channel outlet 1332 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.

[0065] For example, see Figure 4 The box body 131 is cylindrical and includes a substantially annular side wall 1312, which encloses a sewage chamber 1311. The top opening of the sewage chamber 1311 is a dirty dumping port 1314. Figure 3 As shown, the inlet 1331 of the sewage inlet channel can be located at the bottom of the box body 131, and the sewage inlet channel 133 can be located approximately in the middle of the sewage chamber 1311, but it is not limited thereto.

[0066] 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 the sterilization and deodorization effect on the sewage.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] In some optional embodiments, a through hole is provided on the top surface of the hollow shell to receive the liquid drained by the water diversion part.

[0074] The through holes on the top surface of the hollow shell can increase the hollow area of ​​the hollow shell, increase the contact probability between sewage and deodorant, and because the sewage flows from top to bottom, it can easily be directly poured into the hollow shell through the through holes 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 through holes 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.

[0075] 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.

[0076] 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.

[0077] The through hole on the top surface of the hollow shell can be a directly larger hole, or can be a plurality of directly smaller holes. The through hole and the hollow 1341 are both communicated with the inner cavity storing the deodorant inside the hollow shell.

[0078] In some optional embodiments, the water guide portion is located at the lowest point of the solid-liquid separation element 1321 .

[0079] 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.

[0080] 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.

[0081] The solid-liquid separator 1321 has a through hole 1323 connected to the outlet 1332 of the sewage inlet channel, 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 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.

[0082] 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.

[0083] In some optional embodiments, the hollow shell is provided with a through hole 1342 at least at the bottom.

[0084] The through hole 1342 at the bottom of the hollow shell can increase the hollow area of ​​the hollow shell, increase the contact probability between sewage and 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 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.

[0085] The number of the 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 through holes with small diameters.

[0086] 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.

[0087] For example, Figure 5The 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.

[0088] 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 .

[0089] 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.

[0090] 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).

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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 .

[0100] In some optional embodiments, the sewage tank 130 further includes: an in-situ detection module, which is used to detect whether the deodorization module 134 is installed in place.

[0101] The in-situ detection module includes but is not limited to a pressure sensor, a photoelectric sensor or a visual sensor.

[0102] 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

[0103] This embodiment introduces a sewage tank 130 without a 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 that of the embodiment 1.

[0104] 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.

[0105] 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.

[0106] In some optional embodiments, the deodorization module 134 may also be detachably connected to the box cover 132 .

[0107] 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.

[0108] like Figure 4 As shown, the inner wall of the box body 131 refers to the side wall 1312 enclosing and forming the sewage chamber 1311. Figure 7 As shown, the deodorizing module 134 is detachably connected to the side wall 1312. 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 allows the inner 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 wall of the box body 131, so that solid garbage in the dirt is not easily entangled on the deodorizing module 134.

[0109] like Fig. 9As 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 .

[0110] 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.

[0111] 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).

[0112] 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.

[0113] 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.

[0114] 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 .

[0115] 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.

[0116] 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.

[0117] 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

[0118] This embodiment provides a cleaning device including: a floor brush structure 120, a body assembly 110 and a sewage tank 130 of any of the aforementioned embodiments; the body assembly 110 is rotatably connected to the floor brush structure 120, and the sewage tank 130 is installed on the floor brush structure 120 or the body assembly 110.

[0119] 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.

[0120] 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 . Example 4

[0121] In combination with any of the above embodiments, an embodiment of the present disclosure provides a method for determining failure of a deodorization module, which can be applied to, but is not limited to, the cleaning device described in any of the above embodiments, wherein the cleaning device includes a sewage tank, and the cleaning device discharges sewage generated by the cleaning into the sewage tank during cleaning, and the sewage tank includes a deodorization module for deodorizing the sewage discharged into the sewage tank; like Fig.10 As shown, the method includes: Step 1001: determining the accumulated amount of sewage entering the sewage tank based on the first cleaning time of the cleaning device, and then obtaining the accumulated amount of sewage deodorized by the deodorization module; Step 1002: Determine whether the deodorization module is invalid based on the total amount of sewage.

[0122] Here, the steps of the deodorizing module failure determination method may be performed by a controller of the cleaning device.

[0123] In a possible implementation, the cleaning performed by the cleaning device includes the cleaning device performing environmental cleaning (such as floor cleaning) and / or the cleaning device performing self-cleaning.

[0124] During the cleaning process, the cleaning device will draw clean water from the clean water tank and spray it onto the cleaning components such as the roller brush. The cleaning components will clean the surface to be cleaned, and the sewage contaminated by stains can be scraped off by the scraper bar that abuts the roller brush, and sucked into the sewage tank through the sewage suction port of the cleaning device. Therefore, during the cleaning process, the amount of sewage discharged into the sewage tank by the cleaning device is related to the first cleaning time of the cleaning device. The deodorization module can deodorize the sewage by means of deodorizing particles contained in the deodorization module to adsorb odor molecules. The deodorization module can also sterilize the sewage by means of bactericidal materials (such as silver ion materials) contained in the deodorization module. In the following embodiments, the deodorization function of the deodorization module is taken as an example to illustrate the method for determining the failure of the deodorization module.

[0125] In a possible implementation, the first cleaning duration may include the cleaning duration of each cleaning operation of the cleaning device.

[0126] In a possible implementation, the accumulated sewage volume may be the accumulated sewage volume during the first cleaning time. The total sewage volume may be the sum of the accumulated sewage volume determined for each cleaning. In a possible implementation, the first cleaning time may also be the accumulated cleaning time of the cleaning device after the deodorizing module is first installed in the sewage tank.

[0127] In a possible implementation, the total amount of sewage discharged into the sewage tank can be determined based on the first cleaning time and the amount of sewage discharged into the sewage tank per unit time. The sewage discharged into the sewage tank can flow through the deodorization module, or the deodorization module can be immersed in the sewage in the sewage tank, so that the total amount of sewage deodorized by the deodorization module is related to the total amount of sewage discharged into the sewage tank.

[0128] In a possible implementation, the total amount of sewage deodorized by the deodorization module is equal to the total amount of sewage discharged into the sewage tank.

[0129] The deodorization module uses deodorization particles set inside the module to deodorize the sewage. The deodorization module has a failure mechanism. The failure of the deodorization module is related to the amount of sewage filtered by the deodorization module. For example, in the process of filtering sewage, the deodorization particles in the deodorization module adsorb odor molecules to play a deodorizing role. As the amount of sewage filtered by the deodorization module increases, when the adsorption capacity of the deodorization particles is less than or equal to the predetermined adsorption value, the deodorization module cannot effectively deodorize, and then fails.

[0130] In a possible implementation, the total amount of sewage deodorized by the deodorization module can be compared with the total amount of sewage threshold of the deodorization module. If the total amount of sewage deodorized by the deodorization module is less than the total amount of sewage threshold, then the deodorization module is determined to be effective, otherwise, it can be determined that the deodorization module is ineffective. Here, the total amount of sewage threshold can be determined based on the maximum amount of sewage that the deodorization module can process. For example, the total amount of sewage threshold is equal to the maximum amount of sewage that the deodorization module can process.

[0131] In this way, on the one hand, the total amount of sewage deodorized by the deodorization module is used to determine whether the deodorization module has failed, thereby reducing the situation where the deodorization module fails and the deodorization effect is poor due to uncertainty of the deodorization module, thereby improving the user experience. On the other hand, the method of this embodiment uses existing components of the cleaning equipment (such as a controller, a sewage tank full water detection component, etc.) to realize the failure detection of the deodorization module, without adding new components, reducing the corresponding design changes, and saving the corresponding costs.

[0132] In some embodiments, the method further comprises at least one of the following: Determining that the deodorization module fails, and sending failure indication information, wherein the failure indication information is used to indicate to a user that the deodorization module fails; Determine that the deodorizing module is reinstalled based on the sensing information of the first in-place sensor, record the update information of the deodorizing module, send update indication information for user confirmation, and determine whether the deodorizing module is updated based on at least one of the following: If no indication information of a predetermined operation is received within a predetermined time after the update indication information is sent, it is determined that the deodorization module is updated; if indication information of a predetermined operation is received within a predetermined time after the update indication information is sent, it is determined that the deodorization module is not updated, and the update information is removed.

[0133] In a possible implementation, the method for determining the failure of the deodorization module further includes determining that the deodorization module fails and sending failure indication information. Here, the failure indication information may include sound indication information, display indication information, etc. The failure indication information may also include indication information sent to a user terminal, and the failure indication information may include sound indication information, display indication information, etc. to indicate to the user.

[0134] The failure indication information can remind the user to replace the deodorizing module in time, so as to reduce the situation where the deodorizing module fails to be replaced in time and cannot be deodorized and sterilized.

[0135] Here, the first in-situ sensor is used to detect whether the deodorization module is in place. The first in-situ sensor can be arranged in the sewage tank to detect whether the deodorization module is in place.

[0136] In a possible implementation, the first presence sensor may include at least one of the following: a pressure sensor, a photoelectric sensor.

[0137] Here, the first in-position sensor can determine whether the deodorizing module is removed and / or in-position. Furthermore, the first in-position sensor can determine whether the deodorizing module is reinstalled.

[0138] If it is determined that the deodorizing module is reinstalled, the controller may record update information. The update information may record information associated with the reinstalled deodorizing module, such as the start time for indicating the reinstallation of the deodorizing module, the cleaning time of the deodorizing module in the last cleaning device, the total amount of sewage, etc., which are not listed here one by one.

[0139] After the first in-place sensor determines that the deodorizing module is reinstalled, the controller needs to determine whether the user has replaced a brand new deodorizing module or the deodorizing module has not been replaced. Therefore, the controller can send an update indication message for the user to confirm whether the user has replaced a brand new deodorizing module or the deodorizing module has not been replaced.

[0140] In a possible implementation, the update indication information may include voice information, display information, etc.

[0141] If the instruction information of the predetermined operation is not received within the predetermined time after the update instruction information is sent, the controller may default to the user confirming that a new deodorizing module has been replaced. Then, the controller may use the update information of the deodorizing module to re-accumulate the cleaning time, the total amount of sewage, etc.

[0142] If the instruction information of the predetermined operation is received within the predetermined time after the update instruction information is sent, the controller can determine that the user has not replaced the deodorizing module. Then, the controller can remove the update information of the deodorizing module and maintain the accumulation of the existing cleaning time, total amount of sewage and other information.

[0143] In a possible implementation, the predetermined operation may include resetting the deodorizing module, or operating a predetermined button, or operating through a user terminal (such as a mobile phone).

[0144] By sending the update indication information, it is possible to confirm whether the deodorization module has been replaced, thereby reducing misjudgment of the cleaning device and improving the accuracy of determining whether the deodorization module has failed.

[0145] In some embodiments, the cleaning device includes N different cleaning modes, and the sewage discharge per unit time corresponding to each cleaning mode is not exactly the same; The determining, based on the first cleaning time of the cleaning device, the total amount of sewage deodorized by the deodorization module comprises the following: Determine the total amount of sewage based on the second cleaning durations corresponding to the N different cleaning modes during cleaning by the cleaning device and the first predetermined unit time sewage discharge volume corresponding to each cleaning mode; Based on the second cleaning time corresponding to the N different cleaning modes and the second predetermined sewage discharge volume per unit time, the first sewage volumes corresponding to the N different cleaning modes are determined, and the weighted sum of the first sewage volumes corresponding to the N different cleaning modes is determined as the total sewage volume, wherein the weights corresponding to different cleaning modes are not exactly the same.

[0146] Here, the sewage discharge per unit time corresponding to different cleaning modes is not exactly the same.

[0147] Exemplarily, the cleaning mode includes at least one of the following: normal cleaning mode, strong cleaning mode, and self-cleaning mode.

[0148] In a possible implementation, the second cleaning durations corresponding to different cleaning modes include the accumulated cleaning durations corresponding to different cleaning modes in at least one cleaning. Here, the starting time of the accumulated cleaning duration may include the time when the deodorizing module is first installed in the sewage tank.

[0149] The controller in the cleaning device can accumulate the cleaning time of different cleaning modes in each cleaning, and then determine the second cleaning time corresponding to the different cleaning modes.

[0150] In one possible implementation, the sewage discharge volume per first predetermined unit time in each cleaning mode can be predetermined, and based on the second cleaning time corresponding to different cleaning modes, the amount of sewage discharged into the sewage tank in each cleaning mode can be determined, and then the total amount of sewage can be obtained by adding the amount of sewage discharged into the sewage tank in each cleaning mode.

[0151] In a possible implementation, the sewage discharge volume per unit time in each cleaning mode may not be distinguished, and the sewage volume discharged into the sewage tank in each cleaning mode may be determined uniformly with the same second predetermined sewage discharge volume per unit time and the second cleaning duration corresponding to different cleaning modes, and the total amount of sewage may be obtained by weighting. Here, the difference in sewage discharge volume in different cleaning modes is adjusted by weight.

[0152] In this way, by distinguishing the difference in sewage volume under different cleaning modes and refining the calculation method of the total sewage volume, the accuracy of the determined total sewage volume can be improved, thereby improving the accuracy of judging whether the deodorization module has failed.

[0153] In some embodiments, determining whether the deodorization module is invalid according to the total amount of sewage includes: If the total amount of sewage is less than the total amount threshold of sewage, and the product of the number of full water alarms of the sewage tank and the full amount of sewage in the sewage tank is greater than the total amount threshold of sewage removal, it is determined that the deodorization module has failed.

[0154] Here, a water full alarm sensor may be provided in the sewage tank to detect the height of the sewage level. When the sewage level reaches a predetermined level (that is, the sewage in the sewage tank reaches a predetermined alarm total amount), the water full alarm sensor sends a water full alarm to the controller.

[0155] Due to the water absorption capacity of the cleaned surface (such as the ground) and the form of the stains on the cleaned surface (solid, liquid), the actual sewage discharge per unit time of the sewage actually discharged into the sewage tank is not necessarily the same as the sewage discharge per unit time (including the first predetermined sewage discharge per unit time and / or the first predetermined sewage discharge per unit time). Therefore, the determined total amount of sewage is not necessarily the same as the actual total amount of sewage discharged.

[0156] When the water absorption capacity of the cleaning surface is weak, or there is a lot of liquid on the cleaning surface, the total amount of sewage determined by the controller is less than the total amount of sewage actually discharged. That is, when the controller determines that the total amount of sewage is less than the total amount of sewage threshold, the actual total amount of sewage discharged may be greater than the total amount of sewage threshold.

[0157] The amount of sewage discharged into the sewage tank can be determined relatively accurately based on the number of water full alarms in the sewage tank.

[0158] In a possible implementation, the product of the number of sewage tank full alarm times multiplied by the sewage tank full water volume is less than or equal to the total amount of sewage actually discharged into the sewage tank (for example, the user may dump sewage before the full alarm). Therefore, when the product of the number of sewage tank full alarm times multiplied by the sewage tank full water volume is greater than the sewage total volume threshold, the actual total amount of sewage discharged into the sewage tank must be greater than the sewage total volume threshold, and therefore, it can be determined that the deodorization module has failed.

[0159] The minimum total amount of sewage actually discharged into the sewage tank can be determined by the number of times the sewage tank is full. The minimum value is compared with the total amount of sewage threshold to determine whether the deodorization module has failed. This can reduce the judgment error caused by the large error in the total amount of sewage determined by the cleaning time, thereby improving the accuracy of determining whether the deodorization module has failed.

[0160] In some embodiments, the method further includes: determining a theoretical amount of sewage in the sewage tank at the moment when the sewage tank is full of water and an alarm; if the difference between the theoretical amount of sewage in the sewage tank and the full-water alarm sewage amount in the sewage tank exceeds a predetermined error range, correcting the total amount of sewage.

[0161] In a possible implementation, the theoretical sewage volume can be determined based on the sewage volume per unit time. For example, after the sewage tank is reinstalled on the cleaning device, the theoretical sewage volume in the sewage tank can be determined based on the first cleaning time and the sewage volume per unit time.

[0162] The sewage volume of the sewage tank full alarm can be the total amount of sewage in the sewage tank of the cleaning device when the sewage tank is full alarm. The cleaning device can sense the liquid level in the sewage tank through a full water sensor and issue a full water alarm when the full water level is reached. It can be understood that the sewage volume of the full water alarm can be a fixed value.

[0163] Due to the water absorption capacity of the cleaned surface (such as the ground) and the form of the stains on the cleaned surface (solid, liquid), the sewage volume of the sewage tank full alarm is not necessarily the same as the theoretical sewage volume. If the difference between the theoretical sewage volume in the sewage tank and the sewage volume of the sewage tank full alarm exceeds the predetermined error range, then the difference between the theoretical sewage volume and the sewage volume of the sewage tank full alarm is large, and correction is required to improve the accuracy of the total sewage volume.

[0164] In some embodiments, the correcting the total amount of sewage comprises: The absolute value of the difference between the theoretical sewage volume in the sewage tank and the full water alarm sewage volume of the sewage tank is used as the sewage compensation amount; when the total amount of sewage needs to be corrected, if the theoretical sewage volume in the sewage tank is greater than the full water alarm sewage volume of the sewage tank, the total amount of sewage is corrected by subtracting the sewage compensation amount; if the theoretical sewage volume in the sewage tank is less than the full water alarm sewage volume of the sewage tank, the total amount of sewage is corrected by adding the sewage compensation amount.

[0165] If the theoretical sewage volume is greater than the sewage volume set by the sewage tank's full water alarm, it means that the actual sewage discharge per unit time is small, and the controller has overcalculated the sewage flowing into the sewage tank, and the excess part (i.e., the absolute value) needs to be subtracted.

[0166] If the theoretical sewage volume is less than the sewage volume set by the sewage tank's full water alarm, it means that the actual sewage discharge per unit time is large, and the controller has underestimated the sewage flowing into the sewage tank. The uncalculated part of the sewage (i.e. the absolute value) needs to be added to the total amount of sewage.

[0167] In some embodiments, the method further includes: during the period of time when the sewage tank is continuously installed on the cleaning equipment, taking the product of the accumulated cleaning time of the cleaning equipment and the sewage discharge volume per unit time as the theoretical sewage volume in the current sewage tank.

[0168] Here, the time period during which the sewage tank is continuously installed on the cleaning device includes: the continuous time period between when the sewage tank is reinstalled on the cleaning device and when the sewage tank is full of water alarm. The sewage tank can be considered to be emptied when it is reinstalled on the cleaning device. Therefore, the sewage generated by cleaning during this time period is accumulated in the sewage tank. Therefore, by taking the product of the accumulated cleaning time and the sewage discharge per unit time as the theoretical sewage volume in the current sewage tank, the accuracy of determining the theoretical sewage volume can be improved. In some embodiments, the method further includes: It is determined that during the current cleaning process, a water full alarm of the sewage tank is received beyond the expected time, and the total amount of sewage is compensated with the sewage compensation amount.

[0169] Here, the current cleaning process may include the cleaning process between the sewage tank being reinstalled into the cleaning device and the sewage tank being full of water alarm. That is, the current cleaning process is the cleaning process between the sewage tank being empty and the sewage tank being full of water alarm. The controller may sense the in-situ state of the sewage tank through the second in-situ sensor to determine whether the sewage tank is reinstalled into the cleaning device.

[0170] During the current cleaning process, the controller can determine the amount of sewage flowing into the sewage tank based on the cleaning time, and predict the expected time of the full water alarm in combination with the maximum capacity of the sewage tank.

[0171] Due to the water absorption capacity of the cleaned surface (such as the ground) and the form of stains on the cleaned surface (solid, liquid), the actual sewage discharge per unit time of the sewage actually discharged into the sewage tank is not necessarily the same as the sewage discharge per unit time (including the first predetermined sewage discharge per unit time and / or the first predetermined sewage discharge per unit time).

[0172] For example, if there is liquid on the cleaning surface (such as spilled coffee), the actual sewage discharge per unit time is greater than the sewage discharge per unit time, and the water full alarm will be triggered earlier than expected. That is, the total amount of sewage determined based on the sewage discharge per unit time is different from the actual total amount of sewage.

[0173] Here, the sewage compensation amount can be used to compensate the total amount of sewage. For example, if the water full alarm is earlier than the expected time, the total amount of sewage can be updated by adding the sewage compensation amount to the total amount of sewage determined by the controller. This reduces the error of the determined total amount of sewage and improves the accuracy of failure judgment.

[0174] In a possible implementation, the sewage compensation amount may be a fixed value, and the total amount of sewage may be compensated with a specified value. Each time a sewage tank full water alarm is received outside the expected time, the fixed value is used for compensation.

[0175] In some embodiments, the sewage compensation amount is determined based on the length of an interval between the expected time and the time when the water full alarm is received.

[0176] In a possible implementation, the sewage compensation amount is positively correlated with the interval duration.

[0177] In a possible implementation, the product of the interval time and the sewage discharge volume per unit time is equal to the sewage compensation amount. Here, the sewage discharge volume per unit time corresponds to the current cleaning mode.

[0178] For example, when the cleaning equipment has been cleaning for 20 minutes, the controller expects that the water full alarm will be triggered after another 10 minutes of operation. However, the alarm is triggered after only 6 minutes. That is, the interval between the expected time and the time when the water full alarm is received is 4 minutes. Then the sewage compensation amount can be determined based on the sewage discharge volume in 4 minutes. If the expected time arrives before the full water alarm, the compensation for the total amount of sewage can be the total amount of sewage plus the sewage compensation amount. If the expected time arrives after the full water alarm, the compensation for the total amount of sewage can be the total amount of sewage minus the sewage compensation amount.

[0179] In this way, the sewage compensation amount is determined by the interval between the expected time and the time when the full water alarm is received, so that the difference between the sewage discharge volume determined by the current cleaning and the actual sewage discharge volume can be determined, so that the total sewage volume can be compensated more accurately, thereby improving the accuracy of deodorization module failure judgment.

[0180] In some embodiments, the method further includes: determining whether the deodorization module is in the sewage tank based on first sensing information of a first in-situ sensor for sensing whether the deodorization module is in the sewage tank; The determining the total amount of sewage deodorized by the deodorizing module based on the first cleaning time of the cleaning device comprises: The total amount of sewage deodorized by the deodorizing module is determined based on a first cleaning time duration for the cleaning device to perform the cleaning when the deodorizing module is in the sewage tank.

[0181] Here, the first in-situ sensor is used to detect whether the deodorization module is in place. The first in-situ sensor can be arranged in the sewage tank to detect whether the deodorization module is in place.

[0182] Since whether the deodorization module fails is related to the total amount of sewage actually deodorized by the deodorization module, the total amount of sewage deodorized when the deodorization module is in place can be determined by the first in-place sensor, thereby reducing the impact of sewage discharged when the deodorization module is not in place on the total amount of sewage statistics, reducing the error in the total amount of sewage statistics, and improving the accuracy of deodorization module failure judgment. Example 5

[0183] In combination with any of the above embodiments, an embodiment of the present disclosure provides a method for determining failure of a deodorization module, which is applied to a cleaning device, wherein the cleaning device includes a sewage tank, and the cleaning device discharges sewage generated by the cleaning into the sewage tank during cleaning, and the sewage tank includes a deodorization module for deodorizing the sewage discharged into the sewage tank; like Fig.11 As shown, the method includes: Step 1101: Determine whether the deodorization module is invalid based on at least one of the total time the deodorization module is in use in the sewage tank and the total time the deodorization module performs deodorization.

[0184] The cleaning process of the cleaning equipment and the method of discharging sewage into the sewage tank during the cleaning process are as described in any of the above embodiments and will not be repeated here.

[0185] The deodorization module uses deodorization particles disposed inside the module to deodorize the sewage. The deodorization module has a failure mechanism. The failure of the deodorization module is related to the time the deodorization module is exposed to the air and / or sewage. For example, the deodorization module may fail due to oxidation, adsorption of odor molecules, etc. as it is exposed to the sewage tank.

[0186] In a possible implementation, the total time of use may be the total duration of the deodorization module being installed in the sewage tank. For example, the total time of use may include the total time of the cleaning device performing cleaning and the total time of the cleaning device not performing cleaning.

[0187] In a possible implementation, the total deodorization time may be the total time that the deodorization module deodorizes the sewage. For example, the total deodorization time may include the total time that the deodorization module is in the sewage process and / or the total time that the deodorization module is immersed in the sewage.

[0188] In a possible implementation, the total time of use can be compared with a total time threshold of use. If the total time of use is less than the total time threshold of use, then it is determined that the deodorization module is effective, otherwise, it can be determined that the deodorization module is invalid. Here, the total time threshold of use can be determined based on the maximum time that the deodorization module always remains effective in the working environment.

[0189] In a possible implementation, the total deodorization time can be compared with a total deodorization time threshold. If the total deodorization time is less than the total deodorization time threshold, then it is determined that the deodorization module is effective, otherwise, it can be determined that the deodorization module is ineffective. Here, the total deodorization time threshold can be determined based on the maximum time that the deodorization module remains effective in sewage.

[0190] In one possible implementation, when the total usage time and the total deodorization time are used simultaneously to determine whether the deodorization module is effective, if the total usage time is greater than or equal to the total usage time threshold and the total deodorization time is greater than or equal to the total deodorization time threshold, it can be determined that the deodorization module is invalid; otherwise, it can be determined that the deodorization module is effective.

[0191] In this way, whether the deodorization module is invalid is determined by the total time the deodorization module is put into use and the total deodorization time, thereby reducing the situation where the deodorization module fails and the deodorization effect is poor due to the uncertainty of the deodorization module, and improving the user experience.

[0192] In some embodiments, the method further comprises at least one of the following: Based on the second sensing information of the first in-situ sensor for sensing whether the deodorizing module is located in the sewage tank, determining the starting time when the deodorizing module is located in the sewage tank, and determining the total time of use based on the starting time and the current time; The starting time is determined based on the user's indication information, and the total duration of use is determined based on the starting time and the current time.

[0193] Here, the first in-situ sensor is used to detect whether the deodorization module is in place. The first in-situ sensor can be arranged in the sewage tank to detect whether the deodorization module is in place.

[0194] In one possible implementation, the starting moment of the total duration of use can be determined based on the sensing information of the first in-situ sensor. When the first in-situ sensor senses that the deodorization module is installed in the sewage tank, this moment is determined as the starting moment when the deodorization module is in the sewage tank (that is, the starting moment of the total duration of use).

[0195] In a possible implementation, the starting time of the total time of use can be indicated by the user. The user can interact with the cleaning device through a user terminal (such as a mobile phone) associated with the cleaning device, and the user can send instruction information to the cleaning device through the user terminal to determine the starting time when the deodorizing module is in the sewage tank. The user can also set the starting time when the deodorizing module is in the sewage tank by directly communicating with the cleaning device, such as by pressing a button.

[0196] Thus, on the one hand, the first in-situ sensor and the user's indication information can be used to determine the starting time when the deodorizing module is in the sewage tank, thereby improving the accuracy of determining the total time of use, and further improving the accuracy of judging the failure of the deodorizing module. On the other hand, the method of this embodiment can realize the failure detection of the deodorizing module by using the existing components of the cleaning equipment (such as the controller, etc.), without adding new components, reducing the corresponding design changes, and saving the corresponding costs.

[0197] In some embodiments, the method further comprises: The total deodorization time is determined based on the first cleaning time of the cleaning equipment and the shutdown soaking time of the deodorization module in the sewage other than the first cleaning time; wherein the shutdown soaking time includes the interval between the end time of the previous cleaning and the start time of the next cleaning when the cleaning equipment is always in place in the sewage tank, and / or the interval between the time when the cleaning equipment finished cleaning for the last time and the time when the sewage tank is separated from the cleaning equipment.

[0198] It can be understood that the shutdown soaking time does not overlap with the cleaning time. The cleaning time not only includes the time the cleaning equipment takes to clean the floor, but also includes the time the cleaning equipment takes to perform a self-cleaning process.

[0199] In a possible implementation, the first cleaning duration may include the cleaning duration accumulated by the cleaning device during multiple cleaning operations. The controller in the cleaning device may accumulate the cleaning duration of each cleaning operation to determine the first cleaning duration.

[0200] In a possible implementation, the first cleaning duration may be the cumulative cleaning duration of the cleaning device after the deodorizing module is first installed in the sewage tank.

[0201] After the cleaning equipment finishes cleaning, the user may not necessarily clear the sewage in the sewage tank. At this time, the deodorization module is still deodorizing, so the downtime soaking time is still included in the total deodorization time.

[0202] The cleaning device may include a second on-site sensor, and the second on-site sensor is used to detect whether the sewage tank is located on the cleaning device. If the second on-site sensor determines that the sewage tank is detached from the cleaning device during cleaning, it can be considered that the user has cleared the sewage in the sewage tank. Then, the downtime soaking time is the interval between the cleaning end time when the cleaning device completes cleaning and the non-location start time of the sewage tank non-location time period.

[0203] The deodorization time of the deodorization module can be accurately determined by the first cleaning time and the shutdown soaking time, thereby improving the accuracy of the deodorization module failure judgment.

[0204] In some embodiments, the method further comprises: The total time of use is compensated by the duration of the time period during which the sewage tank is not in place; The determining whether the deodorization module is invalid based on the total time the deodorization module is in use in the sewage tank includes: Based on the total time of use to complete the compensation, it is determined whether the deodorization module is invalid.

[0205] Based on the user's usage habits, when the sewage tank is not in place, it can usually be understood that the user cleans the sewage because the deodorization module is not in a deodorizing state, and the failure loss is small. Therefore, the duration of the sewage tank not in place can be used to compensate the total time of use. For example, the total time of use can be updated by subtracting the duration of the sewage tank not in place from the total time of use.

[0206] By compensating the total time of use by the time length, the accuracy of determining the total time of use can be improved, thereby improving the accuracy of judging the failure of the deodorizing module.

[0207] In some embodiments, the method further comprises: Determining the total amount of sewage deodorized by the deodorization module based on a first cleaning time duration for the cleaning device to perform the cleaning; The determining whether the deodorization module is invalid based on at least one of the total time the deodorization module is in use in the sewage tank and the total time the deodorization module performs the deodorization comprises the following: If the total amount of sewage is greater than the total amount of sewage threshold, determining whether the deodorization module is invalid based on at least one of the total time of use and the total time of deodorization; If the total time of use is greater than the total time threshold of use and / or the total time of deodorization is greater than the total time threshold of use, and the total amount of sewage is greater than the total amount of sewage threshold, it is determined that the deodorization module is invalid; If the total time of use is greater than the total time threshold of use and / or the total time of deodorization is greater than the total time threshold of use, and the total amount of sewage is less than or equal to the total amount of sewage threshold, it is determined that the deodorization module is not failed.

[0208] Here, based on the first cleaning time, the implementation method of determining the total amount of sewage to be deodorized by the deodorization module can be as described in any of the above embodiments, which will not be repeated here.

[0209] In a possible implementation, the total amount of sewage can be used for pre-judgment. When the total amount of sewage is greater than the total amount of sewage threshold, it is determined whether the deodorization module has failed based on at least one of the total operating time and the total deodorization time.

[0210] In a possible implementation, after the failure of the deodorization module is determined based on the total time of use and / or the total time of deodorization, the failure status of the deodorization module can be reviewed based on the total amount of sewage. If the failure of the deodorization module is determined based on the total time of use and / or the total time of deodorization, and the failure of the deodorization module is also determined based on the total amount of sewage, then the failure of the deodorization module is finally determined. If the failure of the deodorization module is determined based on the total time of use and / or the total time of deodorization, and the failure of the deodorization module is determined based on the total amount of sewage, then the failure of the deodorization module is finally determined.

[0211] In this way, by combining multiple methods to judge whether the deodorization module has failed, the reliability of determining the failure of the deodorization module is improved and the situation of misjudgment is reduced.

[0212] In some embodiments, the cleaning includes N different cleaning modes, and the sewage discharge per unit time corresponding to each cleaning mode is not exactly the same; The determining the total amount of sewage deodorized by the deodorizing module based on the first cleaning time of the cleaning device comprises: Determine the total amount of sewage based on the second cleaning durations corresponding to the N different cleaning modes during cleaning by the cleaning device and the first predetermined unit time sewage discharge volume corresponding to each cleaning mode; Based on the second cleaning time corresponding to the N different cleaning modes and the second predetermined sewage discharge volume per unit time, the first sewage volumes corresponding to the N different cleaning modes are determined, and the weighted sum of the first sewage volumes corresponding to the N different cleaning modes is determined as the total sewage volume, wherein the weights corresponding to different cleaning modes are not exactly the same.

[0213] Here, the sewage discharge per unit time corresponding to different cleaning modes is not exactly the same.

[0214] Exemplarily, the cleaning mode includes at least one of the following: normal cleaning mode, strong cleaning mode, and self-cleaning mode.

[0215] In a possible implementation, the second cleaning durations corresponding to different cleaning modes include the accumulated cleaning durations corresponding to different cleaning modes in at least one cleaning. Here, the starting time of the accumulated cleaning duration may include the time when the deodorizing module is first installed in the sewage tank.

[0216] The controller in the cleaning device can accumulate the cleaning time of different cleaning modes in each cleaning, and then determine the second cleaning time corresponding to the different cleaning modes.

[0217] In one possible implementation, the sewage discharge volume per first predetermined unit time in each cleaning mode can be predetermined, and based on the second cleaning time corresponding to different cleaning modes, the amount of sewage discharged into the sewage tank in each cleaning mode can be determined, and then the total amount of sewage can be obtained by adding the amount of sewage discharged into the sewage tank in each cleaning mode.

[0218] In a possible implementation, the sewage discharge volume per unit time in each cleaning mode may not be distinguished, and the sewage volume discharged into the sewage tank in each cleaning mode may be determined uniformly with the same second predetermined sewage discharge volume per unit time and the second cleaning duration corresponding to different cleaning modes, and the total amount of sewage may be obtained by weighting. Here, the difference in sewage discharge volume in different cleaning modes is adjusted by weight.

[0219] In this way, by distinguishing the difference in sewage volume under different cleaning modes and refining the calculation method of the total sewage volume, the accuracy of the determined total sewage volume can be improved, thereby improving the accuracy of judging whether the deodorization module has failed.

[0220] In some embodiments, the method further comprises: If the total amount of sewage is less than the total amount threshold of sewage, and the product of the number of full water alarms of the sewage tank and the full amount of sewage in the sewage tank is greater than the total amount threshold of sewage removal, it is determined that the deodorization module has failed.

[0221] Due to the water absorption capacity of the cleaned surface (such as the ground) and the form of the stains on the cleaned surface (solid, liquid), the actual sewage discharge per unit time of the sewage actually discharged into the sewage tank is not necessarily the same as the sewage discharge per unit time (including the first predetermined sewage discharge per unit time and / or the first predetermined sewage discharge per unit time). Therefore, the determined total amount of sewage is not necessarily the same as the actual total amount of sewage discharged.

[0222] When the water absorption capacity of the cleaning surface is weak, or there is a lot of liquid on the cleaning surface, the total amount of sewage determined by the controller is less than the total amount of sewage actually discharged. That is, when the controller determines that the total amount of sewage is less than the total amount of sewage threshold, the actual total amount of sewage discharged may be greater than the total amount of sewage threshold.

[0223] The amount of sewage discharged into the sewage tank can be determined relatively accurately based on the number of water full alarms in the sewage tank.

[0224] In a possible implementation, the product of the number of sewage tank full alarm times multiplied by the sewage tank full water volume is less than or equal to the total amount of sewage actually discharged into the sewage tank (for example, the user may dump sewage before the full alarm). Therefore, when the product of the number of sewage tank full alarm times multiplied by the sewage tank full water volume is greater than the sewage total volume threshold, the actual total amount of sewage discharged into the sewage tank must be greater than the sewage total volume threshold, and therefore, it can be determined that the deodorization module has failed.

[0225] The minimum value of the total amount of sewage actually discharged into the sewage tank can be determined by the number of times the sewage tank is full. The minimum value is compared with the total amount of sewage threshold to determine whether the deodorization module has failed. This can reduce the judgment error caused by the large error in the total amount of sewage determined by the cleaning time, thereby improving the accuracy of determining whether the deodorization module has failed. At the same time, the failure detection of the deodorization module can be realized by using the existing components of the cleaning equipment (such as the controller, etc.), without adding new components, reducing the corresponding design changes, and saving the corresponding costs.

[0226] In some embodiments, the method further includes: determining a theoretical amount of sewage in the sewage tank at the moment when the sewage tank is full of water and an alarm; if the difference between the theoretical amount of sewage in the sewage tank and the full-water alarm sewage amount in the sewage tank exceeds a predetermined error range, correcting the total amount of sewage.

[0227] In a possible implementation, the theoretical sewage volume can be determined based on the sewage volume per unit time. For example, after the sewage tank is reinstalled on the cleaning device, the theoretical sewage volume in the sewage tank can be determined based on the first cleaning time and the sewage volume per unit time.

[0228] The sewage volume of the sewage tank full alarm can be the total amount of sewage in the sewage tank of the cleaning device when the sewage tank is full alarm. The cleaning device can sense the liquid level in the sewage tank through a full water sensor and issue a full water alarm when the full water level is reached. It can be understood that the sewage volume of the full water alarm can be a fixed value.

[0229] Due to the water absorption capacity of the cleaned surface (such as the ground) and the form of the stains on the cleaned surface (solid, liquid), the sewage volume of the sewage tank full alarm is not necessarily the same as the theoretical sewage volume. If the difference between the theoretical sewage volume in the sewage tank and the sewage volume of the sewage tank full alarm exceeds the predetermined error range, then the difference between the theoretical sewage volume and the sewage volume of the sewage tank full alarm is large, and correction is required to improve the accuracy of the total sewage volume.

[0230] In some embodiments, the correcting the total amount of sewage comprises: The absolute value of the difference between the theoretical sewage volume in the sewage tank and the full water alarm sewage volume of the sewage tank is used as the sewage compensation amount; when the total amount of sewage needs to be corrected, if the theoretical sewage volume in the sewage tank is greater than the full water alarm sewage volume of the sewage tank, the total amount of sewage is corrected by subtracting the sewage compensation amount; if the theoretical sewage volume in the sewage tank is less than the full water alarm sewage volume of the sewage tank, the total amount of sewage is corrected by adding the sewage compensation amount.

[0231] If the theoretical sewage volume is greater than the sewage volume set by the sewage tank's full water alarm, it means that the actual sewage discharge per unit time is small, and the controller has overcalculated the sewage flowing into the sewage tank, and the excess part (i.e., the absolute value) needs to be subtracted.

[0232] If the theoretical sewage volume is less than the sewage volume set by the sewage tank's full water alarm, it means that the actual sewage discharge per unit time is large, and the controller has underestimated the sewage flowing into the sewage tank. The uncalculated part of the sewage (i.e. the absolute value) needs to be added to the total amount of sewage.

[0233] In some embodiments, the method further includes: during the period of time when the sewage tank is continuously installed on the cleaning equipment, taking the product of the accumulated cleaning time of the cleaning equipment and the sewage discharge volume per unit time as the theoretical sewage volume in the current sewage tank.

[0234] Here, the time period during which the sewage tank is continuously installed on the cleaning device includes: the continuous time period between when the sewage tank is reinstalled on the cleaning device and when the sewage tank is full of water alarm. When the sewage tank is reinstalled on the cleaning device, it can be considered that the sewage tank is emptied. Therefore, the sewage generated by cleaning during this time period is accumulated in the sewage tank. Therefore, by taking the product of the accumulated cleaning time and the sewage discharge per unit time as the theoretical sewage volume in the current sewage tank, the accuracy of determining the theoretical sewage volume can be improved.

[0235] In some embodiments, the method further comprises: It is determined that during the current cleaning process, a water full alarm of the sewage tank is received beyond the expected time, and the total amount of sewage is compensated with the sewage compensation amount.

[0236] Here, the current cleaning process may include the cleaning process between the sewage tank being reinstalled into the cleaning device and the sewage tank being full of water alarm. That is, the current cleaning process is the cleaning process between the sewage tank being empty and the sewage tank being full of water alarm. The controller may sense the in-situ state of the sewage tank through the second in-situ sensor to determine whether the sewage tank is reinstalled into the cleaning device.

[0237] During the current cleaning process, the controller can determine the amount of sewage flowing into the sewage tank based on the cleaning time, and predict the expected time of the full water alarm in combination with the maximum capacity of the sewage tank.

[0238] Due to the water absorption capacity of the cleaned surface (such as the ground) and the form of stains on the cleaned surface (solid, liquid), the actual sewage discharge per unit time of the sewage actually discharged into the sewage tank is not necessarily the same as the sewage discharge per unit time (including the first predetermined sewage discharge per unit time and / or the first predetermined sewage discharge per unit time).

[0239] For example, if there is liquid on the cleaning surface (such as spilled coffee), the actual sewage discharge per unit time is greater than the sewage discharge per unit time, and the water full alarm will be triggered earlier than expected. That is, the total amount of sewage determined based on the sewage discharge per unit time is different from the actual total amount of sewage.

[0240] Here, the sewage compensation amount can be used to compensate the total amount of sewage. For example, if the water full alarm is earlier than the expected time, the total amount of sewage can be updated by adding the sewage compensation amount to the total amount of sewage determined by the controller. This reduces the error of the determined total amount of sewage and improves the accuracy of failure judgment.

[0241] In a possible implementation, the sewage compensation amount may be a fixed value, and the total amount of sewage may be compensated with a specified value. Each time a sewage tank full water alarm is received outside the expected time, the fixed value is used for compensation.

[0242] In some embodiments, the sewage compensation amount is determined based on the length of an interval between the expected time and the time when the water full alarm is received.

[0243] In a possible implementation, the sewage compensation amount is positively correlated with the interval duration.

[0244] In a possible implementation, the product of the interval time and the sewage discharge volume per unit time is equal to the sewage compensation amount. Here, the sewage discharge volume per unit time corresponds to the current cleaning mode.

[0245] For example, when the cleaning equipment has been cleaning for 20 minutes, the controller expects that the water full alarm will be triggered after another 10 minutes of operation. However, the alarm is triggered after only 6 minutes. That is, the interval between the expected time and the time when the water full alarm is received is 4 minutes. Then the sewage compensation amount can be determined based on the sewage discharge volume in 4 minutes. If the expected time arrives before the full water alarm, the compensation for the total amount of sewage can be the total amount of sewage plus the sewage compensation amount. If the expected time arrives after the full water alarm, the compensation for the total amount of sewage can be the total amount of sewage minus the sewage compensation amount.

[0246] In this way, the sewage compensation amount is determined by the interval between the expected time and the time when the full water alarm is received, so that the difference between the sewage discharge volume determined by the current cleaning and the actual sewage discharge volume can be determined, so that the total sewage volume can be compensated more accurately, thereby improving the accuracy of deodorization module failure judgment. Example 6

[0247] In combination with any of the above embodiments, an embodiment of the present disclosure provides a method for determining failure of a deodorization module, which is applied to a cleaning device, wherein the cleaning device includes a sewage tank, and the cleaning device discharges sewage generated by the cleaning into the sewage tank during cleaning, and the sewage tank includes a deodorization module for deodorizing the sewage discharged into the sewage tank; like Fig.12 Said method comprises: Step 1201: Determine that the number of times the sewage tank is not in place is less than n times the number of times the water full alarm is triggered, where n is greater than or equal to 1 and less than or equal to a predetermined multiple. Step 1202: Determine whether the deodorization module is invalid based on the total amount of sewage deodorized by the deodorization module and the number of water full alarms.

[0248] The cleaning process of the cleaning equipment and the method of discharging sewage into the sewage tank during the cleaning process are as described in any of the above embodiments and will not be repeated here.

[0249] Here, the number of water full alarms can be considered as the number of times the user clears the sewage in the sewage tank, so the amount of sewage cleared by the user in the sewage tank can be determined.

[0250] Here, a method for determining whether the deodorization module is invalid can be selected based on the user's habit of clearing the sewage in the sewage tank. If the user is usually accustomed to clearing the sewage in the sewage tank after it is full, that is, the user is accustomed to clearing the sewage in the sewage tank after receiving a full water alarm, then it can be explained that the amount of sewage cleared by the user and the total amount of sewage actually deodorized have a corresponding relationship. For example, if the sewage in the sewage tank is cleared after receiving a full water alarm every time, then the amount of sewage cleared by the user is equal to the total amount of sewage actually deodorized. Therefore, whether the deodorization module is invalid can be determined by combining the total amount of sewage deodorized by the deodorization module and the amount of sewage cleared by the user.

[0251] Here, whether the user is accustomed to clearing the sewage in the sewage tank after the water full alarm is triggered can be determined based on the relationship between the number of times the sewage tank is not in place and the number of alarms. The closer the relationship between the number of times the sewage tank is not in place and the number of alarms, the higher the probability that the user is accustomed to clearing the sewage in the sewage tank after receiving the water full alarm.

[0252] Here, the range of the predetermined multiple may include greater than 1 and less than or equal to 2. When the number of times the sewage tank is not in place is less than n times the number of times the water full alarm is received, it can be determined that the user is accustomed to clearing the sewage in the sewage tank after receiving the water full alarm.

[0253] By combining the total amount of deodorized sewage and the number of water full alarms to determine whether the deodorization module has failed, it is possible to review whether the deodorization module has failed, thereby improving the reliability of failure determination.

[0254] In some embodiments, determining whether the deodorization module is invalid according to the total amount of sewage deodorized by the deodorization module and the number of water full alarms includes: The total amount of sewage is greater than the total amount of sewage threshold, and the product of the number of full water alarms of the sewage tank and the full amount of sewage in the sewage tank is greater than the total amount of sewage removal threshold, and it is determined that the deodorization module has failed.

[0255] In one possible implementation, the sewage total volume threshold is greater than or equal to the sewage removal total volume threshold.

[0256] By combining the total amount of deodorized sewage and the number of water full alarms to determine whether the deodorization module has failed, it is possible to review whether the deodorization module has failed, thereby improving the reliability of failure determination. Example 7

[0257] In combination with any of the above embodiments, an embodiment of the present disclosure provides a method for determining failure of a deodorization module, which is applied to a cleaning device, wherein the cleaning device includes a sewage tank, and the cleaning device discharges sewage generated by the cleaning into the sewage tank during cleaning, and the sewage tank includes a deodorization module for deodorizing the sewage discharged into the sewage tank; the sewage tank also includes a detection module for detecting water quality parameters of the sewage in the sewage tank; like Fig.13 Said method comprises: Step 1301: Determine whether the deodorization module is invalid based on the water quality parameters detected by the detection module under predetermined conditions.

[0258] Here, the detection module can be arranged in the sewage tank to detect the water quality parameters of the sewage.

[0259] When the deodorization module treats the sewage (deodorizes and / or sterilizes), the water quality parameters of the sewage will change. Therefore, it can be determined whether the deodorization module is invalid based on the water quality parameters of the sewage.

[0260] Here, the water quality parameters may include odor parameters of sewage, etc.

[0261] In one possible implementation, the current water quality parameter can be compared with the water quality parameter threshold value, and if the water quality condition reflected by the water quality parameter is worse than the water quality condition reflected by the water quality parameter threshold value, it can be determined that the deodorization module has failed. Here, the water quality parameter threshold value can be determined based on the ability of the deodorization module to improve water quality when it fails.

[0262] Here, the predetermined condition can be determined based on the need to accurately determine the water quality parameters. For example, during the cleaning process of the cleaning device, the sewage in the sewage tank is in motion, which will affect the accuracy of the water quality parameter detection result. Therefore, the water quality parameters can be detected when the sewage is in a static state.

[0263] The influence of the deodorization module on the water quality can be directly determined through water quality parameters, thereby improving the accuracy of the deodorization module failure judgment.

[0264] In some embodiments, the detection module includes at least one of the following: a resistance detection module, a photoelectric detection module; The water quality parameters include at least one of the following: The resistance value of the sewage detected by the resistance detection module; The photoelectric detection module detects the turbidity of the sewage.

[0265] In one possible implementation, the deodorization module performs deodorization by means of adsorption and the silver ion sterilization will cause changes in the turbidity of the sewage, which in turn will easily cause changes in the resistivity and turbidity (visibility) of the sewage.

[0266] In a possible implementation, the resistance detection module may be implemented by using a probe for water fullness detection. The resistance detection module may include two probes inserted into the sewage to measure the resistance between the two probes, thereby determining the sewage resistance value.

[0267] In a possible implementation, the photoelectric detection module may include a transmitting end for emitting light and a receiving end for receiving the light. The light emitted by the transmitting end is attenuated by the sewage and received by the receiving end. The turbidity of the sewage is determined by comparing the emitted light and the received light.

[0268] The influence of the deodorization module on the water quality can be directly determined by the resistance value and / or turbidity, thereby improving the accuracy of the judgment of the failure of the deodorization module.

[0269] In some embodiments, the water quality parameter detected under predetermined conditions includes at least one of the following: The detection module detects water quality parameters when the sewage tank is in a predetermined posture; The detection module detects the water quality parameters after the sewage tank is in a static state for a predetermined static period of time.

[0270] Here, comparison can be made based on the water quality parameters obtained under the same conditions. On the one hand, this can improve the measurement accuracy. On the other hand, it can also reduce the impact of changes in water quality parameters under different conditions on the judgment, thereby improving the accuracy of the deodorization module's judgment.

[0271] In a possible implementation, the predetermined posture may include the state of the sewage tank when the cleaning device is located at the base station for charging. In this state, impurities in the sewage are in a precipitated state, which can reduce the impact of the part with more impurities at the bottom of the sewage tank on the water quality.

[0272] In a possible implementation, the detection may be performed after the sewage tank has been stationary for a predetermined period of time, so as to reduce fluctuations in the detected water quality parameters caused by sewage movement and thus reduce the impact on the detection results.

[0273] In some embodiments, the determining whether the deodorization module is invalid based on the water quality parameters detected by the detection module under predetermined conditions includes: The method determines whether the deodorization module is invalid based on the change value of the water quality parameter determined by the detection module within the detection time period.

[0274] In a possible implementation, the detection time period may only cover a single cleaning process, such as a time period after a predetermined static time after the cleaning device is static after a single cleaning, so as to detect the change in the deodorization capacity of the deodorization module in a relatively short time.

[0275] In a possible implementation, the detection time period may cover multiple cleaning processes. For example, the sewage may be detected after each cleaning is completed, so that the detection spans a longer period of time to detect changes in the deodorization capacity of the deodorization module.

[0276] By detecting the change in the water quality parameters during the time period, the change in the deodorization capacity of the deodorization module can be determined, thereby more intuitively determining whether the deodorization module has failed and improving the accuracy of failure judgment.

[0277] In some embodiments, the determining whether the deodorization module is invalid based on the water quality parameters detected by the detection module under predetermined conditions includes one of the following: The water quality parameter exceeds the water quality parameter threshold, and based on at least one of the total time the deodorization module is in use in the sewage tank, the total time the deodorization module performs the deodorization, and the total amount of sewage deodorized by the deodorization module, it is determined whether the deodorization module is invalid; It is determined that water quality parameters obtained by the detection module from M detections of the sewage each exceed a water quality parameter threshold, and the deodorization module is determined to be invalid, wherein M is greater than or equal to 2.

[0278] In one possible implementation, after determining that the deodorization module may have failed through water quality parameters, the failure status of the deodorization module can be reviewed in combination with the commissioning time, the total deodorization time and / or the total amount of sewage, thereby improving the accuracy of failure judgment.

[0279] Here, the implementation method of judging the failure status of the deodorization module by the operation time, the total deodorization time and / or the total amount of sewage is as described in any of the above embodiments and will not be repeated here.

[0280] The water quality parameters are reviewed through multiple tests, thereby improving the reliability of the determined water quality parameters and thus improving the reliability of failure judgment.

[0281] In one possible implementation, the sewage may be tested multiple times after a single cleaning.

[0282] In a possible implementation, failure judgment may be performed in combination with tests performed after multiple cleanings, and one or more tests may be performed after each cleaning. Example 8

[0283] In combination with any of the above embodiments, an embodiment of the present disclosure provides a method for determining failure of a deodorization module, which is applied to a cleaning device, wherein the cleaning device includes a sewage tank, and the cleaning device discharges sewage generated by the cleaning into the sewage tank during cleaning, and the sewage tank includes a deodorization module for deodorizing the sewage discharged into the sewage tank; like Fig.14 As shown, the method includes: Step 1401: Based on the usage parameters of the cleaning equipment after the deodorizing module is initially installed in the sewage tank, a prediction model is used to predict a first failure state of the deodorizing module; wherein the prediction model is trained using historical usage parameters and a second failure state of the deodorizing module under the historical usage parameters.

[0284] Among them, the prediction model can be autonomously learned, tested and adjusted according to the recently accumulated usage parameters and failure conditions through the artificial intelligence AI model.

[0285] In one possible implementation, the predictive model may include a machine learning model.

[0286] Here, the usage parameter is used to characterize the user's usage habits. The prediction model can predict the first failure state based on the user's usage habits.

[0287] In a possible implementation, predicting the first failure state of the deodorization module includes at least one of the following: Predicting the moment of failure of the deodorization module; Predict the remaining time of failure of the deodorization module.

[0288] The historical usage parameters and the second failure state may be obtained from different users. For example, the historical usage parameters may be big data of users using the cleaning device.

[0289] The second failure state may include the length of time required for the deodorization module to fail under different historical usage parameters.

[0290] In this way, the failure state of the deodorization module is predicted by the prediction model, which can reduce the failure of the deodorization module and poor deodorization effect caused by the uncertain deodorization module, thereby improving the user experience.

[0291] In some embodiments, the usage parameters include at least one of the following: a third cleaning time duration for the cleaning device to perform cleaning; The frequency with which the cleaning equipment performs cleaning; frequency of the sewage tank being out of place; The ambient temperature of the sewage tank; The dirtiness of the sewage in the sewage tank.

[0292] The above-mentioned usage parameters can have different effects or correlation effects on the service life of the deodorization module to a certain extent; generally speaking, the remaining service life of the deodorization module decreases with the increase of the third cleaning time, the frequency of cleaning, the frequency of the sewage tank being absent, the ambient temperature, or the degree of dirtiness of the sewage, wherein the ambient temperature of the sewage tank can be obtained through a temperature sensor or through the Internet, and the higher the ambient temperature of the sewage tank, the faster the bacteria will breed and the sewage will become smelly, thereby accelerating the consumption of the service life of the deodorization module; the degree of dirtiness of the sewage in the sewage tank can be collected through a dirtiness sensor in the sewage suction pipe in the cleaning equipment, and the greater the dirtiness of the sewage, the easier it will be to consume the service life of the deodorization module.

[0293] The third cleaning time, cleaning frequency, frequency of sewage tank absence, ambient temperature and degree of sewage dirtiness are interrelated and influence each other; for example, the frequency of sewage tank absence can reflect the situation of sewage tank emptying, and thus can certainly reflect the frequency and time of cleaning; the third cleaning time of cleaning reflects the user usage time within a certain period of time, and the frequency of cleaning can be roughly calculated based on the usage time of each time; other related relationships are not listed here one by one.

[0294] In one possible implementation, the third cleaning duration may include a total duration of a single cleaning.

[0295] In a possible implementation, the third cleaning duration may include the accumulated cleaning duration after the deodorization module is updated.

[0296] The presently disclosed embodiment also provides a cleaning device, which includes a sewage tank and a controller.

The sewage tank includes a deodorization module for deodorizing the sewage discharged into the sewage tank. The controller is used to execute the method described in any of the above embodiments.
