[0002] With the development of smart homes, cleaning equipment such as floor scrubbers has become widely used. Furthermore, more and more users are focusing on the user experience of these cleaning devices.

[0003] However, in related technologies, the wastewater tank in cleaning equipment is prone to bacterial growth and odor, resulting in a poor user experience. Summary of the Invention

[0004] In view of this, this application provides a sewage tank component, a cleaning device, and a method for controlling the cleaning device, which can at least partially prevent the sewage tank from easily breeding bacteria and producing odors.

[0005] In a first aspect, this application provides a cleaning device. The cleaning device includes: a floor brush, a wastewater tank, a liquid pump, and a control module. The floor brush has a wastewater inlet channel. The wastewater tank is mounted on the floor brush. The wastewater tank includes a first cavity and a second cavity. The first cavity has a wastewater inlet connected to the wastewater inlet channel, and a first water level detection device is installed within the first cavity. The liquid pump is located in the wastewater tank and is used to pump the wastewater from the first cavity to the second cavity. The control module is electrically connected to the first water level detection device and the liquid pump. The control module is triggered when the first water level detection device detects that the water level in the first cavity has reached a first preset water level, and controls the liquid pump to adjust its current first rotation speed to a second rotation speed, where the second rotation speed is greater than the first rotation speed.

[0006] According to the cleaning device of this application embodiment, a first chamber and a second chamber are provided within a wastewater tank. An inlet is provided in the first chamber, and a pump is installed to transfer wastewater from the first chamber to the second chamber. A control module controls the pump. In this way, when wastewater and solid waste enter the first chamber through the inlet, the control module can control the pump to transfer the wastewater to the second chamber, while the solid waste is stored in the first chamber. This allows for the separation of solid waste and wastewater within a single wastewater tank, facilitating cleaning and maintenance, and at least to some extent reducing the risk of bacterial growth and unpleasant odors in the wastewater tank.

[0007] Furthermore, a first water level detection device is installed in the first chamber to detect the water level height within it. When the water level in the first chamber reaches a first preset level, it indicates that there is a significant amount of waste liquid in the first chamber. The control module, triggered by the first water level detection device reaching the first preset level, increases the speed of the pump, effectively ensuring that the waste liquid in the first chamber is promptly pumped to the second chamber. This effectively separates solid waste from the waste liquid, facilitating the cleaning and maintenance of the wastewater tank. It also reduces the risk of bacterial growth and odor in the wastewater tank and prevents backflow of waste liquid from the inlet in the first chamber.

[0083] The roller brush 22 is rotatably mounted on the brush body 21. The rotation center line of the roller brush 22 extends in the left-right direction, which facilitates the roller brush 22 to roll in the front-back direction to clean the surface to be cleaned (e.g., the floor). For ease of description, the following description uses the floor as an example.

[0084] The fan 4 is installed inside the housing 11. The connection between the fan 4 and the housing 11 includes, but is not limited to, adhesive bonding, welding, snap-fitting, or screw connection.

For example, the floor brush body 21 has an installation space, and the wastewater tank component 3A can be mounted within the installation space.

[0087] Wastewater tank component 3A includes wastewater tank 3 and a pump ( Figure 1 and Figure 2 (Not shown in the image).

[0088] The wastewater tank 3 is mounted on the brush body 21. For example, the wastewater tank 3 is detachably mounted on the brush body 21. This facilitates the removal of the wastewater tank 3 for the discharge of wastewater and cleaning of the tank. The detachable connection between the wastewater tank 3 and the brush body 21 includes, but is not limited to, screw connections and snap-fit ​​connections.

[0089] Of course, it is understood that in other embodiments, the wastewater tank 3 may also be mounted on the housing 11.

[0090] For easier cleaning of wastewater tank 3, please refer to [link / reference]. Figure 3 and Figure 4 , Figure 3 According to Figure 1 A three-dimensional view of the sewage tank 3 shown; Figure 4 According to Figure 3 The wastewater tank 3 shown is a perspective sectional view at line AA. Exemplarily, the wastewater tank 3 includes a tank body 31 and a cover 32. The top of the tank body 31 is open, and the cover 32 is placed on the tank body 31.

[0091] For example, the cover 32 is rotatably mounted on top of the tank 31 to switch between an open and closed position. This allows the tank 31 to be opened by flipping the cover 32 for easy cleaning of the wastewater tank 3. Flipping the cover 32 also allows the tank 31 to be closed, creating a relatively enclosed space for storing wastewater.

[0092] For example, to prevent leakage from the sewage tank 3, a seal (not shown) may be provided between the cover 32 and the tank body 31.

[0093] Please continue reading. Figure 4 and combined Figure 5, Figure 5 According to Figure 3 The diagram shows an exploded view of the sewage tank 3. The sewage tank 3 has an inlet 341 and an outlet 346. The shape of the inlet 341 is, but is not limited to, circular, rectangular, elliptical, or irregular.

[0094] The sewage inlet 341 is connected to the sewage inlet channel of the floor brush 2. The blower 4 is used to drive the airflow through the sewage inlet channel and the sewage inlet 341 into the sewage tank 3 and out of the sewage tank 3 from the exhaust port 346.

[0095] The airflow generated when the blower 4 rotates can provide suction for the cleaning equipment 100, so that the liquid and solid dirt generated by the roller brush 22 when cleaning the floor are sucked into the sewage tank 3 through the sewage inlet 341 of the sewage tank 3 and stored in the sewage tank 3.

[0096] Please continue reading. Figure 4 The sewage tank 3 has a first cavity 34 and a second cavity 35.

[0097] The second cavity 35 and the first cavity 34 can be arranged in a horizontal direction. In other embodiments, the second cavity 35 and the first cavity 34 can also be arranged in a vertical direction.

[0098] For example, please refer to Figure 4 As shown, the second cavity 35 and the first cavity 34 are distributed along the left-right direction. Specifically, in order to increase the cleaning area, the length direction of the roller brush 22 is generally in the left-right direction. Based on this, by distributing the second cavity 35 and the first cavity 34 along the left-right direction, it is beneficial to make full use of the space on the brush body 21 and improve the rationality of the structural layout of the cleaning device 100. As another example, the second cavity 35 and the first cavity 34 can also be distributed in the front-back direction.

[0099] The sewage inlet 341 is located in the first cavity 34, that is, the first cavity 34 has the aforementioned sewage inlet 341.

The liquid pump 7 can be, but is not limited to, an active pump or a passive pump. The liquid pump 7 is used to pump the wastewater in the first chamber 34 to the second chamber 35.

[0101] The connection methods between the liquid pump 7 and the sewage tank 3 include, but are not limited to, snap-fit, screw connection or adhesive.

[0102] Specifically, when the blower 4 rotates, the liquid and solid waste generated by the roller brush 22 during floor cleaning are first drawn into the first chamber 34 through the inlet 341 of the wastewater tank 3. Then, the liquid in the first chamber 34 is pumped to the second chamber 35 by the liquid pump 7 and stored there, while the solid waste that entered the first chamber 34 is stored there. In this way, the solid waste and liquid waste can be separated using a single wastewater tank 3, making it easier to clean and maintain the wastewater tank 3, thereby reducing the risk of bacteria growth and odor generation in the wastewater tank 3 to some extent.

[0103] Please continue reading. Figure 4 The first cavity 34 is equipped with a first water level detection device 5. The first water level detection device 5 is used to detect whether the water level in the first cavity 34 has reached a first preset water level.

[0104] The control module 12 is electrically connected to the first water level detection device 5 and the pump 7. The control module 12 can adjust the speed of the pump 7 according to the water level detection result of the first water level detection device 5.

[0105] Specifically, when the water level in the first chamber 34 is lower than the first preset water level, it indicates that there is relatively little sewage in the first chamber 34. The current speed of the pump 7 can promptly remove the sewage from the first chamber 34, and the pump 7 can maintain its current speed. When the water level in the first chamber 34 reaches the first preset water level, it indicates that there is relatively much sewage in the first chamber 34. The control module 12, triggered by the first water level detection device 5 detecting that the water level in the first chamber 34 has reached the first preset water level, can control the pump 7 to adjust its current first speed to a second speed, which is greater than the first speed. This effectively ensures that the sewage in the first chamber 34 is promptly pumped into the second chamber 35, effectively separating solid waste from sewage, facilitating the cleaning and maintenance of the sewage tank 3, reducing the risk of bacteria growth and odor in the sewage tank 3 to a certain extent, and preventing the sewage in the first chamber 34 from flowing back from the inlet 341.

[0106] It is worth noting that when the cleaning equipment 100 is turned on, the water level in the sewage tank 3 has already reached the first preset water level. At this time, the control module 12 is triggered by the first water level detection device 5 detecting that the water level in the first cavity 34 has reached the first preset water level, and can control the liquid pump 7 to run directly at the second speed when it is turned on.

[0107] For example, please continue reading Figure 4 The first part 321 of the cover 32 fits with the box 31 to enclose the first cavity 34. The second part 322 of the cover 32 fits with the box 31 to enclose the second cavity 35.

[0108] For example, to facilitate the formation of the first cavity 34 and the second cavity 35 described above, the sewage tank 3 includes a partition 33. The first cavity 34 and the second cavity 35 are separated by the partition 33 in the horizontal direction.

[0109] Please continue reading. Figure 4 The first part 321 of the cover 32, the box 31, and the partition 33 cooperate to form a first cavity 34. The second part 322 of the cover 32, the box 31, and the partition 33 cooperate to form a second cavity 35.

[0110] For example, please continue reading Figure 4 To facilitate the discharge of air carrying liquid and solid waste from the wastewater tank 3, a duct 351 is formed on the top wall of the second part 322, i.e., the second cavity 35. One end of the duct 351 is connected to the first cavity 34, and the other end is connected to an exhaust port 346 located on the wall panel of the second cavity 35. In this way, airflow can be directly discharged from the exhaust port 346 through the duct 351 without passing through the second cavity 35.

[0111] In some embodiments of this application, please refer to Figure 5 The first water level detection device 5 includes a first electrode 51 and a second electrode 52.

[0112] The first electrode 51 and the second electrode 52 are fixed to the inner wall of the first cavity 34 at a distance from each other. The fixing methods between the first electrode 51 and the second electrode 52 and the first cavity 34 include, but are not limited to, adhesive bonding, welding, snap-fitting, or screw connection. In other examples, a portion of the first electrode 51 may be embedded in the wall panel of the sewage tank 3. A portion of the second electrode 52 may also be embedded in the wall panel of the sewage tank. This application does not impose specific limitations in this regard.

[0113] Both the first electrode 51 and the second electrode 52 are electrically connected to the control module 12.

[0114] Specifically, when the water level of the waste liquid in the first cavity 34 is relatively low and it is not in contact with the first electrode 51 or the second electrode 52, or is only in contact with one of the first electrode 51 and the second electrode 52, the first electrode 51 and the second electrode 52 are in an insulated state. At this time, the water level in the first cavity 34 is lower than the first preset water level.

[0115] When the water level of the waste liquid in the first chamber 34 is relatively high, and the waste liquid simultaneously contacts the first electrode 51 and the second electrode 52, the first electrode 51 and the second electrode 52 achieve electrical conductivity under the action of the waste liquid in the first chamber 34. At this time, the water level in the first chamber 34 reaches the first preset water level. Triggered by the electrical conductivity of the first electrode 51 and the second electrode 52, the control module 12 controls the pump 7 to adjust its current first rotation speed to a second rotation speed. In this way, the method of using the first electrode 51 and the second electrode 52 in conjunction to detect the water level in the first chamber 34 has a simple structure and low cost.

[0116] For example, in order to ensure that the pump 7 can pump the waste liquid in the first chamber 34 to the second chamber 35 in a timely manner, the horizontal height of the first electrode 51 and the horizontal height of the second electrode 52 are both lower than the horizontal height of the middle part of the first chamber 34 in the vertical direction.

[0117] It can be understood that the middle part of the first cavity 34 in the vertical direction refers to the location of the central plane formed by the set of points equidistant from the bottom wall and the top wall of the first cavity 34. Similar descriptions in the following text should be understood in the same way and will not be repeated.

[0118] For example, in order to ensure that the pump 7 can pump the sewage in the first chamber 34 to the second chamber 35 in a timely manner, the pump 7 is located in the first chamber 34, and the horizontal height of the inlet of the pump 7 is lower than the horizontal height of the first electrode 51 and the second electrode 52.

[0119] For example, please continue reading Figure 5 The bottom wall of the first cavity 34 has a groove 315. The inlet of the liquid pump 7 is located in the groove 315. This allows the inlet of the liquid pump 7 to be positioned at a lower position on the bottom wall of the first cavity 34, facilitating smooth liquid pumping by the liquid pump 7.

[0120] For example, please refer to Figure 6 , Figure 6 According to Figure 1 The diagram shows the electrical connection between the control module 12 and the first water level detection device 5 and the second water level detection device 6. The control module 12 has a first port 121 and a second port 122. The first port 121 is electrically connected to the first electrode 51. The second port 122 is electrically connected to the second electrode 52. When the waste liquid in the first cavity 34 simultaneously contacts the first electrode 51 and the second electrode 52, a closed loop is formed between the first electrode 51, the second electrode 52, and the control module 12. The first electrode 51 and the second electrode 52 are electrically connected under the influence of the waste liquid in the first cavity 34. Therefore, the circuit design between the first electrode 51, the second electrode 52, and the control module 12 is relatively simple and low-cost.

[0121] It is understood that the implementation of the first water level detection device 5 is not limited to this. In other embodiments, the first water level detection device 5 may also be a water level sensor.

[0122] Please refer to some embodiments of this application. Figure 6 and combined Figure 7 , Figure 7 This is a schematic diagram of the cover of the sewage tank shown in Figure 5. A second water level detection device 6 is installed inside the second cavity 35. The horizontal height of the second water level detection device 6 is higher than the horizontal height of the middle of the second cavity 35 in the vertical direction. The second water level detection device 6 is used to detect whether the water level in the second cavity 35 has reached a second preset water level. The control module 12 is electrically connected to the second water level detection device 6. When the second water level detection device 6 detects that the water level in the second cavity 35 has reached the second preset water level, the control module 12 is triggered by the second water level detection device 6 detecting that the water level in the second cavity 35 has reached the second preset water level, and controls the cleaning equipment 100 to stop.

[0123] In this way, when the control module 12 stops the cleaning equipment 100, it can remind the user that the sewage tank 3 is full, so that the user can clean the sewage tank 3 in a timely manner and prevent the sewage tank 3 from overflowing, making the cleaning equipment 100 more intelligent. Furthermore, setting the horizontal height of the second water level detection device 6 to be higher than the midpoint of the second cavity 35 in the vertical direction ensures that the cleaning equipment 100 is only stopped after a certain amount of sewage has been stored in the second cavity 35, avoiding frequent shutdowns caused by the control module 12 and improving the user experience.

[0124] For example, please continue reading Figure 6 and Figure 7 The second water level detection device 6 includes a third electrode 61 and a fourth electrode 62. The third electrode 61 and the fourth electrode 62 are fixed to the inner wall of the second cavity 35 at a distance from each other. For example, the third electrode 61 and the fourth electrode 62 are disposed at a distance from each other on the top wall of the second cavity 35. The fixing methods between the third electrode 61 and the fourth electrode 62 and the second cavity 35 include, but are not limited to, adhesive bonding, welding, snap-fitting, or screw connection. In other examples, a portion of the third electrode 61 may be embedded in the wall panel of the sewage tank 3. A portion of the fourth electrode 62 may also be embedded in the wall panel of the sewage tank 3. This application does not impose specific limitations in this regard.

[0125] The third electrode 61, the fourth electrode 62, and the control module 12 are all electrically connected.

[0126] Specifically, when the water level of the sewage in the second cavity 35 is low and it is not in contact with the third electrode 61 or the fourth electrode 62, or is only in contact with one of the third electrode 61 or the fourth electrode 62, the third electrode 61 and the fourth electrode 62 are in an insulated state. At this time, the water level in the second cavity 35 is lower than the second preset water level.

[0127] When the water level in the second chamber 35 is high, and the water in the second chamber 35 simultaneously contacts both the third electrode 61 and the fourth electrode 62, the third electrode 61 and the fourth electrode 62 achieve electrical conductivity under the influence of the water in the second chamber 35. This indicates that the water level in the second chamber 35 has reached the second preset water level. The control module 12, triggered at least by the electrical conductivity of the third electrode 61 and the fourth electrode 62, controls the cleaning equipment 100 to stop. In this way, the method of using the third electrode 61 and the fourth electrode 62 to detect the water level in the second chamber 35 is simple in structure and low in cost.

[0128] For example, please continue reading Figure 6 The control module 12 has a third port 123 and a fourth port 124. The third port 123 is electrically connected to the third electrode 61. The fourth port 124 is electrically connected to the fourth electrode 62. When the contaminated liquid in the second cavity 35 simultaneously contacts the third electrode 61 and the fourth electrode 62, a closed loop is formed between the third electrode 61, the fourth electrode 62, and the control module 12. The third electrode 61 and the fourth electrode 62 are electrically connected under the influence of the contaminated liquid in the second cavity 35. Therefore, the circuit design between the third electrode 61, the fourth electrode 62, and the control module 12 is relatively simple and low in cost.

[0129] Specifically, the level signals of the third electrode 61 and the second electrode 52 are the same, and the level signals of the first electrode 51 and the fourth electrode 62 are the same. For example, if both the first port 121 and the fourth port 124 output a high level, then the level signals of the first electrode 51 and the fourth electrode 62 are both high-level signals. Similarly, if both the second port 122 and the third port 123 output a high level, then the level signals of the third electrode 61 and the second electrode 52 are both high-level signals. This helps ensure the reliability of the operation of the first water level detection device and the second water level detection device 6.

[0130] It is understood that the implementation of the second water level detection device 6 is not limited to this. In other embodiments, the second water level detection device 6 may also be a water level sensor.

[0131] For example, the control module 12 is triggered by the electrical conduction of the third electrode 61 and the fourth electrode 62, and the electrical conduction between them reaches a first preset duration, thereby controlling the cleaning device 100 to stop. For details, please refer to... Figure 8 , Figure 8This diagram illustrates the sloshing of waste liquid within the second cavity 35 during the movement of the cleaning device 100. The second cavity 35 has a first wall 342 and a second wall 343 facing each other in the front-to-back direction. During the back-and-forth movement of the cleaning device 100 while cleaning the floor, the waste liquid within the second cavity 35 impacts the first wall 342 and the second wall 343 in the front-to-back direction, generating surges. This can easily lead to accidental contact between the surges and the third electrode 61 and the fourth electrode 62, causing a brief electrical conduction between them, resulting in erroneous shutdown control of the cleaning device 100 by the control module 12. Based on this, in this embodiment, the control module 12 is triggered by the electrical conduction of the third electrode 61 and the fourth electrode 62, and the electrical conduction of the two electrodes reaches the first preset duration, thereby controlling the cleaning equipment 100 to stop. This can avoid the problem of the cleaning equipment 100 stopping due to the short-term electrical conduction of the third electrode 61 and the fourth electrode 62 caused by the surge in the second cavity 35, which is beneficial to improving the reliability of the cleaning equipment 100.

[0132] As mentioned above, during the back-and-forth movement of the cleaning device 100, the contaminant in the second chamber 35 will impact the first wall surface 342 and the second wall surface 343 in the back-and-forth direction within the second chamber 35, generating surges. Please continue reading. Figure 8 When the sewage hits the first wall surface 342, the sewage will generally follow... Figure 10 The dashed arrow F1 in the diagram reverses upwards, creating a surge. At this point, the water level is highest near the first wall surface 342 and lowest in the area near the middle of the second cavity 35 in the front-to-back direction. Similarly, when the sewage impacts the second wall surface 343, the sewage will generally flow along... Figure 10 The solid arrow F2 in the middle reverses upward to form a surge. At this time, the water level of the sewage is the highest at the second wall surface 343, and the water level is the lowest in the middle area of ​​the second cavity 35 in the front-back direction.

[0133] As described above, the highest point of the surge often occurs near the first wall 342 or the second wall 343. Furthermore, since the surge is formed by back-and-forth swaying, the highest water level of the surge will not simultaneously occur near both the first wall 342 and the second wall 343. Based on this, please refer to... Figure 9 , Figure 9 According to Figure 7The diagram shows a top-down front view of the cover 32. Exemplarily, in the horizontal plane, a first center line O1 exists between the vertical projections of the first wall surface 342 and the second wall surface 343. The vertical projection of the third electrode 61 is located between the first center line O1 and the vertical projection of the first wall surface 342, and the vertical projection of the fourth electrode 62 is located between the first center line O1 and the vertical projection of the second wall surface 343. This allows the third electrode 61 to be positioned relatively close to the first wall surface 342, and the fourth electrode 62 to be positioned relatively close to the second wall surface 343. Therefore, even if a surge occurs during the movement of the cleaning device 100 before the actual water level in the second cavity 35 reaches the second preset water level, the surge will not simultaneously contact the third electrode 61 and the fourth electrode 62 when their horizontal heights are the same. This avoids the problem of the cleaning device 100 shutting down due to a short-term electrical conduction between the third electrode 61 and the fourth electrode 62 caused by a surge within the second cavity 35, thus improving the reliability of the cleaning device 100's operation. Furthermore, when the sewage tank 3 includes an air duct 351 located on the top wall of the second cavity 35, it is advantageous to make full use of the space on the front and rear sides of the air duct 351 to arrange the third electrode 61 and the fourth electrode 62, avoiding interference between the third electrode 61, the fourth electrode 62 and the air duct 351, resulting in a more reasonable structural layout.

[0134] It is understood that in other embodiments, the horizontal height of the third electrode 61 may also be higher than the horizontal height of the fourth electrode 62.

[0135] Based on this, for example, in the horizontal plane, there is a first sub-centerline O11 between the vertical projection of the first wall surface 342 and the first centerline O1. There is a second sub-centerline O12 between the vertical projection of the second wall surface 343 and the first centerline O1. The vertical projection of the third electrode 61 is located between the first sub-centerline O11 and the vertical projection of the first wall surface 342, and the vertical projection of the fourth electrode 62 is located between the second sub-centerline O12 and the vertical projection of the second wall surface 343. In this way, the third electrode 61 can be positioned relatively close to the first wall surface 342, and the fourth electrode 62 can be positioned relatively close to the second wall surface 343. Therefore, when the actual water level in the second cavity 35 has not yet reached the second preset water level, even if a surge occurs during the movement of the cleaning equipment 100, the surge will not simultaneously contact the third electrode 61 and the fourth electrode 62. This avoids the problem of the cleaning equipment 100 stopping due to a short-term electrical conduction between the third electrode 61 and the fourth electrode 62 caused by a surge within the second cavity 35, thus improving the reliability of the cleaning equipment 100. Furthermore, when the wastewater tank 3 includes an air duct 351 located on the top wall of the second cavity 35, it is advantageous to fully utilize the space on both sides of the air duct 351 to arrange the third electrode 61 and the fourth electrode 62, avoiding interference between the third electrode 61, the fourth electrode 62, and the air duct 351, resulting in a more rational structural layout.

[0136] In other embodiments, for example, the vertical projection of the third electrode 61 is located between the first sub-center line O11 and the first center line O1. For example, the vertical projection of the fourth electrode 62 is located between the second sub-center line O12 and the first center line O1.

[0137] As mentioned earlier, during the forward and backward movement of the cleaning device 100, even if the sewage in the second cavity 35 impacts the first wall 342 and the second wall 343 in the forward and backward direction, causing surges, the water level is lowest in the area near the middle of the second cavity 35 in the forward and backward direction. Based on this, in some embodiments, the third electrode 61 and the fourth electrode 62 can be located at the same horizontal level and spaced apart in the left and right direction. Furthermore, the third electrode 61 and the fourth electrode 62 are positioned in the middle of the second cavity 35 in the forward and backward direction. Therefore, when the actual water level in the second cavity 35 has not yet reached the second preset water level, even if surges occur during the movement of the cleaning device 100, the surges will not simultaneously contact the third electrode 61 and the fourth electrode 62. This avoids the problem of the cleaning device 100 stopping due to short-term electrical conduction of the third electrode 61 and the fourth electrode 62 caused by surges in the second cavity 35, thus improving the reliability of the cleaning device 100.

[0138] In some embodiments of this application, please refer to Figure 10 , Figure 10 According to Figure 5The diagram shows the body 31 of the sewage tank 3. A drain hole 332 is provided on the partition 33.

[0139] The horizontal height of the drain hole 332 is higher than the horizontal height of the first water level detection device 5 (that is, the first electrode 51 and the second electrode 52), higher than the horizontal height of the third electrode 61, and higher than the horizontal height of the fourth electrode 62.

[0140] In this way, during the use of the cleaning equipment 100, on the one hand, it helps to ensure that the sewage in the first chamber 34 is pumped into the second chamber 35 by the pumping pump 7, rather than entering the second chamber 35 from the first chamber 34 through the drain hole 332; on the other hand, when the sewage in the second chamber 35 has simultaneously contacted the third electrode 61 and the fourth electrode 64, but due to a circuit failure between the third electrode 61 and the fourth electrode 62, the water level in the second chamber 35 cannot be effectively detected, or the third electrode 61 and the fourth electrode 62 are electrically connected. Before the first preset time period is reached, the control module 12 cannot control the cleaning equipment 100 to stop in time. In addition, the liquid pump 7 continuously pumps sewage into the second chamber 35, causing the water level in the second chamber 35 to reach the horizontal height of the drain hole 332. The drain hole 332 can be used to relieve pressure in the second chamber 35, so that the sewage in the second chamber 35 that has reached the horizontal height of the drain hole 332 can flow back into the first chamber 34 through the drain hole 332, which to a certain extent avoids the overflow problem of the second chamber 35 of the sewage tank 3.

[0141] For example, the opening shape of the drain hole 332 includes, but is not limited to, a circle, a rectangle, a triangle, or an irregular shape.

[0142] For example, the vertical distance between the drain hole 332 and the inner top wall of the sewage tank 3 is greater than 0 and less than or equal to 5 mm. For instance, the distance between the drain hole 332 and the inner top wall of the sewage tank 3 is 1 mm, 2 mm, 3 mm, or 4 mm.

[0143] For example, the horizontal height of the third electrode 61 is higher than or the same as the horizontal height of the fourth electrode 62. The horizontal height of the first electrode 51 is lower than the horizontal height of the second electrode 52. The control module 12 is triggered by the electrical connection between the third electrode 61 and the first electrode 51 to control the cleaning equipment 100 to stop.

[0144] Specifically, as mentioned above, when the second chamber 35 is full of waste liquid, and the waste liquid flows back into the first chamber 34 through the drain hole 332, the backflow of waste liquid causes the water level in the first chamber 34 to rise. Since the horizontal height of the first electrode 51 is lower than that of the second electrode 52, the first electrode 51 contacts the waste liquid before the second electrode 52. Furthermore, since the horizontal height of the third electrode 61 is higher than or equal to that of the fourth electrode 62, and the horizontal height of the drain hole 332 is higher than that of the third electrode 61, the waste liquid in the second chamber 35 will also contact the third electrode 61. Moreover, during the use of the cleaning equipment 100, the pump 7 continuously draws waste liquid from the first chamber 34 into the second chamber 35. Therefore, the waste liquid in the first chamber 34 and the waste liquid in the second chamber 35 can form a conductive circuit through the pump 7, thereby enabling electrical conduction between the first electrode 51 and the third electrode 61. In this way, the electrical conductivity between the first electrode 51 and the third electrode 61 can be used to indicate that the sewage tank 3 is nearly full. This triggers the control module 12 to shut down the cleaning equipment 100, allowing the user to promptly empty the sewage tank 3 and clean it, preventing overflow. This makes the cleaning equipment 100 more intelligent. Furthermore, when the fourth electrode 62 is lower than the third electrode 61, it avoids the problem of the water level in the second cavity 35 being low and not yet full due to the electrical conductivity between the fourth electrode 62 and the first electrode 51, for example, when the water level has not reached the third electrode 61, thus preventing the cleaning equipment 100 from mistakenly triggering a shutdown signal.

[0145] For example, the vertical distance between the first electrode 51 and the inner bottom wall of the first cavity 34 is 3mm to 10mm. This helps to ensure that the horizontal height of the first electrode 51 is relatively low, which facilitates the timely detection of sewage flowing back into the first cavity 34 through the pressure relief hole, so that the control module 12 can control the cleaning equipment 100 to stop in a timely manner.

[0146] For example, the vertical distance between the first electrode 51 and the inner bottom wall of the first cavity 34 is 4mm, 5mm, 6mm, 7mm, 8mm or 9mm.

[0147] For example, the horizontal height of the first electrode 51 is lower than or level with the horizontal height of the sewage inlet 341. This helps to ensure that the horizontal height of the first electrode 51 is relatively low, which facilitates the timely detection of sewage flowing back into the first cavity 34 through the pressure relief hole, so that the control module 12 can control the cleaning equipment 100 to stop in a timely manner.

[0148] For example, when the vertical distance between the first electrode 51 and the inner bottom wall of the first cavity 34 is 3mm to 10mm, the vertical distance between the second electrode 52 and the inner bottom wall of the first cavity 34 is 8mm to 15mm. This helps to ensure that the first electrode 51 and the second electrode 52 have a certain height difference, which can avoid the problem of frequent gear shifting of the liquid pump 7.

[0149] Please refer to some embodiments of this application. Figure 10 The liquid pump 7 is located inside the first cavity 34. The partition 33 is provided with a liquid delivery port 331. The opening shape of the liquid delivery port 331 includes, but is not limited to, circular, rectangular or irregular shapes.

[0150] The outlet of the pump 7 is connected to the delivery port 331, and the horizontal height of the delivery port 331 is not lower than the horizontal height of the drain hole 332. This helps to prevent the delivery port 331 from being submerged by the sewage in the second chamber 35 when the water in the second chamber 35 is not depressurized by the drain hole 332, thus avoiding a decrease in the operational reliability of the pump 7 and ensuring that the sewage in the first chamber 34 can be reliably pumped into the second chamber 35.

[0151] For example, the vertical distance between the liquid inlet 331 and the inner top wall of the sewage tank 3 is greater than 0 and less than or equal to 5 mm. For instance, the distance between the liquid inlet 331 and the inner top wall of the sewage tank 3 is 1 mm, 2 mm, 3 mm, or 4 mm.

[0152] In some embodiments of this application, please refer to Figure 11 , Figure 11 According to Figure 1 The diagram shows the electrical connections of the cleaning equipment 100. The floor brush 2, for example, has a first conductive contact 23 on its body 21. The first conductive contact 23 is electrically connected to the control module 12 and the power supply module 13. The wastewater tank 3 has a second conductive contact 36. The second conductive contact 36 is electrically connected to the pump 7, the first water level detection device 5, and the second water level detection device 6. When the wastewater tank 3 is installed on the floor brush 2, the second conductive contact 36 contacts and is electrically connected to the first conductive contact 23. In this way, by utilizing the cooperation of the first conductive contact 23 and the second conductive contact 36, not only can the first water level detection device 5 and the pump 7 be electrically connected to the control module 12 and the power supply module 13, but the wiring is also simple and easy to assemble.

[0153] Based on any of the above embodiments, the cleaning device 100 may further include an alarm module 15. When the third electrode 61 is electrically connected to the fourth electrode 62, or when the third electrode 61 is electrically connected to the first electrode 51, and the control module 12 controls the cleaning device 100 to stop, the control module 12 may control the alarm module 15 to issue an alarm prompt so that the user can clean the sewage tank 3 in a timely manner.

[0154] For example, the reminder module 15 can be a voice module. When the third electrode 61 and the fourth electrode 62 are electrically connected, or when the third electrode 61 and the first electrode 51 are electrically connected, and the control module 12 controls the cleaning equipment 100 to stop, the control module 12 can control the voice module to broadcast the fault code.

[0155] For example, the reminder module 15 can be a display module. When the third electrode 61 and the fourth electrode 62 are electrically connected, or when the third electrode 61 and the first electrode 51 are electrically connected, and the control module 12 controls the cleaning equipment 100 to stop, the control module 12 can control the display module to display the fault code.

[0156] This application also provides a control method for a cleaning device. The cleaning device is any of the cleaning devices described in the above-mentioned technical solutions.

[0157] Please see Figure 12 , Figure 12 A flowchart illustrating a control method for the cleaning equipment provided in this application. The control method for the cleaning equipment provided in this application includes the following steps:

[0158] S100: Receives power-on command.

[0159] Specifically, users can trigger the power button on the device to input a power-on command to the cleaning equipment, or they can use a mobile terminal, such as a mobile phone, to wirelessly interact with the cleaning equipment and input a power-on command to the cleaning equipment. There are no specific restrictions or requirements.

[0160] S200: Controls the liquid pump to operate at the first speed.

[0161] Specifically, after receiving the user's power-on command, the control module controls the liquid pump to operate at a first rotational speed. This first rotational speed can be a preset value within the control module's control logic. This preset value can be adjusted according to actual needs.

[0162] S310: Detects the water level in the first chamber.

[0163] Specifically, the water level in the first cavity is detected using a first water level detection device. For example, when the first water level detection device includes a first electrode and a second electrode, the water level in the first cavity is detected by utilizing the electrical conductivity between the first electrode and the second electrode.

[0164] S410: After the water level in the first chamber reaches the first preset water level, control the pump to run at a second speed; wherein the second speed is greater than the first speed.

[0165] Specifically, when the first and second electrodes are electrically connected, it indicates that the water level in the first cavity has reached the first preset water level. The control module can then control the pump to operate at a second rotation speed. When the first and second electrodes are not electrically connected, it indicates that the water level in the first cavity has not reached the first preset water level; in this case, the pump maintains its current first rotation speed.

[0166] According to the control method of the cleaning equipment in the embodiments of this application, after receiving the start command, the pump is controlled to run at a first speed. After detecting that the water level in the first chamber reaches a first preset water level, the pump is controlled to run at a second speed greater than the first speed. This can effectively ensure that the sewage in the first chamber is pumped to the second chamber in a timely manner, effectively achieving the separation of solid sewage and sewage, facilitating the cleaning and maintenance of the sewage tank, and reducing the risk of bacteria growing and odors being generated in the sewage tank to a certain extent.

[0167] For example, the first rotational speed ranges from 66 revolutions per second (r / s) to 134 r / s. This facilitates the timely pumping of wastewater from the first chamber to the second chamber, effectively separating solid waste from the liquid, making the wastewater tank easier to clean and maintain, and reducing the risk of bacteria growth and odor generation in the wastewater tank to some extent.

[0168] For example, the first rotational speed can be 70 r / s, 75 r / s, 80 r / s, 85 r / s, 90 r / s, 95 r / s, 100 r / s, 105 r / s, 110 r / s, 115 r / s, 120 r / s, 125 r / s, 130 r / s, 132 r / s, or 133 r / s.

[0169] For example, the ratio of the second rotational speed to the first rotational speed ranges from 1.2 to 2. This facilitates the timely pumping of wastewater from the first chamber to the second chamber, effectively separating solid waste from the liquid, making the wastewater tank easier to clean and maintain, and reducing the risk of bacteria growth and odor generation in the wastewater tank to some extent.

[0170] For example, the ratio of the second speed to the first speed is 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, or 1.95.

[0171] Please see Figure 13 , Figure 13A flowchart of another control method for the cleaning equipment provided in this application. After controlling the liquid pump to operate at a first speed, the control method for the cleaning equipment further includes:

[0172] S320: Detects the water level in the second chamber.

[0173] Specifically, a second water level detection device can be used to detect the water level in the second cavity. For example, when the second water level detection device includes a third electrode and a fourth electrode, the electrical conductivity between the third electrode and the fourth electrode can be used to detect the water level in the second cavity.

[0174] S420: Control the cleaning equipment to stop after the water level in the second chamber reaches the second preset water level.

[0175] Specifically, when the third and fourth electrodes are not conductive, it indicates that the water level in the second chamber has not reached the second preset water level. When the third and fourth electrodes are conductive, it indicates that the water level in the second chamber has reached the second preset water level. Reaching the second preset water level is a necessary condition for controlling the shutdown of the cleaning equipment.

[0176] In this way, the water level of the sewage in the second chamber can be detected by the second water level detection device, which makes it easier to control the cleaning equipment 100 to stop and remind the user that the sewage tank 3 is full, so that the user can clean the sewage tank 3 in time and prevent the sewage tank 3 from overflowing. The cleaning equipment 100 is more intelligent.

[0177] Please refer to some embodiments of this application. Figure 13 After the water level in the second chamber reaches the second preset water level, the specific steps for controlling the cleaning equipment to stop are as follows:

[0178] S420: After the water level in the second chamber reaches the second preset water level and remains there for the first preset duration, control the cleaning equipment to stop.

[0179] Specifically, as described above, the second cavity has a first wall and a second wall facing each other in the front-to-back direction. During the back-and-forth movement of the cleaning equipment while cleaning the floor, the liquid in the second cavity impacts the first and second walls in the front-to-back direction, generating surges. This can easily lead to the surges making accidental contact with the third and fourth electrodes, causing a short-term electrical conduction between the third and fourth electrodes, resulting in mis-control of the cleaning equipment's shutdown. Therefore, in this embodiment, after the water level in the second cavity reaches a second preset level and remains there for a first preset duration, the cleaning equipment is stopped. This avoids the problem of the cleaning equipment stopping due to short-term electrical conduction between the third and fourth electrodes caused by surges in the second cavity.

[0180] Understandably, this first preset duration can be set according to actual needs.

[0181] For example, the first preset duration ranges from 0.2 seconds (s) to 1 second. This avoids the problem of the cleaning equipment shutting down due to short-term electrical conduction of the third and fourth electrodes caused by surges in the second cavity.

[0182] For example, the first preset duration is 0.25s, 0.3s, 0.35s, 0.4s, 0.45s, 0.48s, 0.5s, 0.55s, 0.6s, 0.65s, 0.7s, 0.75s, 0.8s, 0.85s, 0.9s, or 0.95s.

[0183] In some embodiments of this application, please refer to Figure 14 , Figure 14 A flow chart of another control method for the cleaning equipment provided in this application. When the wastewater tank includes a drain hole, the horizontal height of the third electrode is higher than or equal to the horizontal height of the fourth electrode. When the horizontal height of the first electrode is lower than the horizontal height of the second electrode, after controlling the pump to operate at a first speed, the control method for the cleaning equipment includes:

[0184] S330: After the third electrode and the first electrode are electrically connected, control the cleaning equipment to stop.

[0185] Specifically, since the horizontal height of the third electrode is higher than or the same as that of the fourth electrode, the second chamber is considered full when the wastewater comes into contact with the third electrode, meeting the shutdown condition. However, if the circuit between the third and fourth electrodes malfunctions and cannot effectively detect the water level in the second chamber, or if the electrical conduction between the third and fourth electrodes has not reached the first preset duration, the control module cannot control the cleaning equipment to stop because it does not receive a shutdown command. In this embodiment, since the horizontal height of the first electrode is lower than that of the second electrode, the third electrode can be electrically connected to the first electrode in a timely manner under the action of the pump. After the third electrode and the first electrode are electrically connected, the cleaning equipment is controlled to stop. This facilitates timely reminders to the user to drain the wastewater from the tank, allowing the user to clean the tank promptly and preventing overflow. This makes the cleaning equipment more intelligent.

[0186] Based on any of the above embodiments, please refer to Figure 15 , Figure 15 A flowchart illustrating another control method for the cleaning equipment provided in this application. The specific steps for controlling the pump to operate at a second rotation speed after the water level in the first chamber reaches a first preset water level are as follows:

[0187] S410: After the water level in the first chamber reaches the first preset water level, control the pump to run at the second speed for the second preset time.

[0188] In this way, after the pump runs at the second speed for the second preset time, the pump speed can be controlled again based on the water level in the first chamber. At this time, when the water level in the first chamber still reaches the preset water level, the pump runs at the second speed for the second preset time again. When the water level in the first chamber is lower than the preset water level, the pump is controlled to run at the first speed.

[0189] This avoids the problem of frequent high and low speed switching of the pump, which helps to extend the service life of the pump.

[0190] For example, the second preset duration can be less than or equal to 10 seconds. For instance, the second preset duration can be 2 seconds, 3 seconds, 4 seconds, 5 seconds, 6 seconds, 7 seconds, 8 seconds, or 9 seconds.

[0191] In the description of this specification, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples without contradicting each other.

[0192] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
