[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on December 12, 2023, with application number 202311711012.0 and entitled “Cleaning Equipment and Control Method for Cleaning Equipment,” the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present disclosure relates to the technical field of cleaning equipment, and in particular to a cleaning equipment and a control method for the cleaning equipment. Background Art

[0004] With technological advancements and social progress, more and more households are using mopping machines instead of traditional mops. Unlike traditional sweeping and vacuuming, mopping machines require water or other liquid detergents to clean the floor. Therefore, mopping machines typically include a water tank to store clean water or cleaning liquid. Since wastewater must be collected along with the wastewater, most mopping machines also have a wastewater tank to store wastewater and garbage. This tank is usually mounted on the mopping machine.

[0005] In the related art, when some mopping machines clean the areas under beds and sofas, the machine body needs to lie down at a large angle or even lie flat. At this time, the sewage in the sewage tank is easy to splash, and the splashed sewage will be carried up by the air and sprayed out of the mopping machine.

DETAILED DESCRIPTION

[0039] Embodiments of the present disclosure are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0040] The cleaning device 100 according to an embodiment of the present disclosure is described below with reference to FIG. 1 to FIG. 9 . The present disclosure also provides a control method for the cleaning device 100 .

[0041] As shown in Figures 1 to 9, the cleaning device 100 of the disclosed embodiment includes: a floor brush 201, a body 202, a sewage tank 10, a micro switch, and a controller. The body 202 is rotatably mounted on the floor brush 201. The body 202 has a normal working position and a flat working position relative to the floor brush 201. The inclination angle of the flat working position is lower than the inclination angle of the normal working position. It can be understood that the floor brush 201 can clean the dirt by moving on the cleaning surface to pick up dirt attached during the movement. The body 202 is rotatably mounted on the floor brush 201, which makes it convenient for users to clean low areas. The sewage tank 10 can store the dirty liquid after the floor brush 201 cleans the dirt.

[0042] In addition, according to the change of the working environment of the cleaning device 100, the body 202 has a normal working position and a lying flat working position relative to the brush 201. The normal working position is the position of the body 202 shown in Figure 2. At this time, the inclination angle of the body 202 relative to the horizontal plane is at least 30°, such as 30°, 45°, 60° and 90°, etc. The user can clean the regular floor normally, and the user's body is generally in an upright or slightly bent state; the lying flat working position is the position of the body 202 shown in Figure 1. At this time, the inclination angle of the body 202 relative to the horizontal plane can be less than 15°, such as 0°, 3° and 5°, etc. The user can clean low areas (such as under the bed, the bottom of the cabinet and the bottom of the coffee table, etc.), and the user's body can be in a state of bending at a large angle. The body 202 can lower the overall height of the cleaning device 100 by lying flat, thereby adapting to the working environment when cleaning low areas, thereby improving the adaptability of the cleaning device 100 to different working environments.

[0043] 5 , the sewage tank 10 is provided on the fuselage 202 and includes a first chamber 11 and a second chamber 12. The first chamber 11 and the second chamber 12 are interconnected. The sewage tank 10 can protect and support its internal structure.

[0044] The cleaning device 100 further includes a suction device, which is disposed above the sewage tank and is connected to the first chamber 11 through a connecting channel and to the second chamber 12 through a suction channel 172 .

[0045] As shown in Figures 1 and 2, the microswitch is arranged between the body 202 and the floor brush 201 or on one of them. When the body 202 is in the lying flat working position, the microswitch is triggered, and the controller is electrically connected to the microswitch. The microswitch is used to detect whether the body 202 reaches the lying flat working position, and the controller is used to adjust the pressure of the first chamber 11 and / or the second chamber 12 when the body 202 is in the lying flat working position.

[0046] As shown in Figure 5 , when the main body 202 is nearly flat and the sewage tank 10 is tilted significantly, the distance between the sewage level and the first suction port is short. If the main body 202 is operated at the pressure in the first chamber 11 or the second chamber 12 of the main body 202 during normal cleaning, sewage may enter the suction device along with the airflow. Therefore, when the main body 202 is tilted, the pressure in the first chamber 11 or the second chamber 12 must be adjusted to ensure that the sucked sewage or waste is drawn into the sewage tank 10 without excessive suction force or splashing of liquid into the suction device through the first suction port and the HEPA.

[0047] Specifically, by adjusting the pressure in the second chamber 12 to be greater than the pressure in the first chamber 11, even if the sewage cannot flow into the second chamber 12 under the action of gravity due to the fuselage 202 lying down, the sewage in the first chamber 11 can flow into the second chamber 12 through the pressure, so that the fuselage 202 can lie flat.

[0048] Therefore, when the body 202 is tilted, the micro switch is triggered, and the controller can adjust the pressure of the first chamber 11 or the second chamber 12 to ensure that the sucked dirty liquid or dirt can be sucked into the sewage tank 10, without the suction force being too strong or the liquid splashing into the suction device through the first suction port and HEPA.

[0049] Specifically, as shown in Figures 3, 5 and 9, the sewage tank 10 includes: a sewage tank body 15 and a partition 16, the partition 16 is arranged in the sewage tank body 15, and the sewage tank 10 is divided into a first chamber 11 and a second chamber 12 by the partition 16, and a gap 164 is provided on the partition 16; a sewage suction channel 13 is also provided in the sewage tank 10, and the outlet of the sewage suction channel 13 is located in the first chamber 11. The sewage sucked in by the sewage suction channel 13 is filtered and the solid waste is stored in the first chamber 11, and the sewage flows into the second chamber 12 through the gap 164.

[0050] Specifically, the sewage suction channel 13 passes through the first chamber 11 and the second chamber 12 , and a sewage outlet 131 is formed in the first chamber 11 . A first suction port is provided at the upper end of the sewage tank 10 , and a connecting channel is defined between the first suction port and the sewage outlet 131 . Among them, the first suction port and the sewage outlet 131 are connected to each other through a connecting channel. When the cleaning device 100 starts cleaning, the interior of the first chamber 11 is drawn into a high-pressure environment under the action of suction. Under the high-pressure state in the first chamber 11, the sewage suction channel 13 draws the dirt on the floor brush 201 into the first chamber 11 through the sewage outlet 131 of the sewage suction channel 13, so that the dirt collection work of the cleaning device 100 can be completed in advance, and the first suction port and the sewage outlet 131 of the sewage suction channel 13 are in different directions, so that the sewage or dirt discharged from the sewage outlet 131 of the sewage suction channel 13 in the first chamber 11 can be effectively away from the first suction port, which is conducive to achieving the water-gas separation effect in the first chamber 11, thereby reducing the risk of sewage being sucked into the first suction port, reducing the equipment failure rate, and improving the sewage extraction capacity of the cleaning device 100.

[0051] As shown in FIG5 , a suction channel 172 is further provided within the wastewater tank 10. One end of the suction channel 172 communicates with the first suction port, and the lower end of the suction channel 172 communicates with the second chamber 12. Specifically, the connection between the suction channel 172 and the second chamber 12 allows the pressure within the second chamber 12 to be greater than the pressure within the first chamber 11. Even if the wastewater cannot flow into the second chamber 12 due to gravity if the fuselage 202 is lying flat, the pressure can still force the wastewater in the first chamber 11 into the second chamber 12, allowing the fuselage 202 to lie flat.

[0052] 5, 6 and 9, the first chamber 11 plays an auxiliary role in separating solid dirt and liquid sewage from the dirt, and the second chamber 12 plays the role of accommodating the liquid sewage. The first chamber 11 and the second chamber 12 are connected to each other through the notch 164 on the partition 16, so that the sewage in the first chamber 11 can be guided into the second chamber 12. The dirt on the floor brush 201 is sucked into the first chamber 11 through the sewage outlet 131 under the suction effect transmitted along the sewage suction channel 13. The dirt entering the first chamber 11 is sucked again from the first chamber 11 through the filter element 19 and the partition 16 into the second chamber 12.

[0053] Furthermore, the controller is electrically connected to the suction device, and after the micro switch is triggered, the controller adjusts the power of the suction device. That is, by adjusting the power of the suction device, the pressure of the first chamber 11 or the second chamber 12 can be adjusted.

[0054] Specifically, the duty cycle of the suction device can be increased first and then decreased. That is, when the housing 202 tilts to a certain degree, the microswitch on the rotating shaft closes. After receiving the signal indicating the microswitch is closed, the controller adjusts the power of the suction device. The power of the suction device first increases and then decreases. The power of the suction device after adjustment is less than the power before adjustment. This ensures that after the housing 202 tilts to a certain degree, sewage will not enter the first suction port of the sewage tank 10 along with the airflow.

[0055] Alternatively, the duty cycle of the suction device can be first decreased and then increased. That is, when the housing 202 tilts to a certain degree, the microswitch on the rotating shaft closes. Upon receiving the signal indicating the microswitch is closed, the controller adjusts the power of the suction device. The power of the suction device first decreases and then increases. The power of the suction device after adjustment is less than the power before adjustment. This ensures that after the housing 202 tilts to a certain degree, sewage will not enter the first suction port of the sewage tank 10 along with the airflow.

[0056] The cleaning device 100 further includes a first adjustment component, which is disposed at the connecting channel. The first adjustment component is used to adjust the cross-sectional area of ​​the connecting channel to adjust the pressure in the first chamber 11 and the second chamber 12. Specifically, the pressure in the second chamber 12 and the first chamber 11 can be adjusted by adjusting the size of the caliber of the connecting channel. If the power of the suction device is not changed, the rotation speed of the suction device is fixed. If the cross-sectional area of ​​the connecting channel between the suction device and the first chamber 11 is reduced, the pressure in the second chamber 12 will increase (the vacuum degree will increase), and the pressure in the first chamber 11 will decrease (the vacuum degree will decrease).

[0057] The first adjustment assembly includes a first driving member and a first adjusting member. The first adjusting member is disposed in the connecting channel and is a rotatable baffle. The first driving member drives the first adjusting member to rotate, thereby changing the cross-sectional area of ​​the connecting channel. Of course, the first adjusting member can also be other structures that can adjust the cross-sectional area of ​​the connecting channel.

[0058] The cleaning device 100 further includes a second adjustment component, which is disposed at the suction channel 172. The second adjustment component is used to adjust the cross-sectional area of ​​the suction channel 172 to adjust the pressure in the first chamber 11 and the second chamber 12. Specifically, the pressure in the second chamber 12 and the first chamber 11 can be adjusted by adjusting the size of the diameter of the suction channel 172. If the power of the suction device is not changed, the rotation speed of the suction device is fixed. Increasing the cross-sectional area of ​​the suction channel 172 between the suction device and the second chamber 12 will increase the pressure in the second chamber 12 (increase the vacuum degree) and reduce the pressure in the first chamber 11 (decrease the vacuum degree).

[0059] The second adjustment assembly includes a second driving member and a second adjusting member. The second adjusting member is disposed in the suction channel 172 and is a rotatable baffle. The second driving member drives the second adjusting member to rotate, thereby changing the cross-sectional area of ​​the suction channel 172. Of course, the second adjusting member can also be other structures that can adjust the cross-sectional area of ​​the suction channel 172.

[0060] Specifically, as shown in Figures 4, 6, and 8, the sewage tank 10 also includes a first water level detection assembly 20 and a second water level detection assembly 30. The sewage tank body 15 has a first chamber 11 and a second chamber 12, which are interconnected. The first water level detection assembly 20 is at least used to detect whether the second chamber 12 has reached a first full water position when the body 202 is in the normal operating position. The second water level detection assembly 30 is at least partially located in the first chamber 11 and is at least used to detect whether the first chamber 11 has reached a second full water position when the body 202 is in the flat operating position. When the water level reaches the first full water position, the first water level detection assembly 20 issues a stop suction signal; when the water level reaches the second full water position, the second water level detection assembly 30 issues a stop suction signal.

[0061] Furthermore, when the body 202 is in the normal working position, the first water level detection assembly 20 can detect whether the dirty liquid in the second chamber 12 has reached the first full water position. When the first full water position is reached, the first water level detection assembly 20 sends a suction stop signal to the cleaning device 100. This avoids the risk of failure caused by the dirty liquid being sucked into the suction channel 172 provided in the second chamber 12 and entering undesirable structures within the cleaning device 100.

[0062] When the body 202 is in the lying working position, the second water level detection component 30 can detect whether the dirty liquid in the first chamber 11 in this state has reached the second water-full position. When the second water-full position is reached, it sends a stop suction signal to the cleaning device 100. In this way, the risk of failure caused by the dirty liquid being sucked into the suction channel 172 provided in the solid-liquid holding chamber and causing the dirty liquid to enter the unexpected structure inside the cleaning device 100 can be avoided. Therefore, through the coordinated work of the first water level detection component 20 and the second water level detection component 30, it can be ensured that the dirty liquid in the second chamber 12 and the first chamber 11 will not be sucked into the unexpected structure, thereby improving the safety of the electronic components and the comprehensive practicality of the cleaning device 100 under different working conditions.

[0063] Therefore, by providing the sewage tank 10, the water level information when the body 202 is in the lying working position can be detected, thereby avoiding the problem of the cleaning device 100 failing when the sewage is sucked into its internal unwanted structure when in the lying working state.

[0064] According to some optional embodiments of the present disclosure, in combination with Figures 6 and 8, the first water level detection assembly 20 includes a first liquid level detection member 21 and a second liquid level detection member 22, and the first liquid level detection member 21 and the second liquid level detection member 22 are both arranged in the second chamber 12. The first liquid level detection member 21 and the second liquid level detection member 22 are selectively electrically connected to detect whether the second chamber 12 reaches the first water full position.

[0065] The second water level detection assembly 30 includes a third liquid level detection component 31 and a fourth liquid level detection component. The third liquid level detection component 31 is arranged in the first chamber 11, and the fourth liquid level detection component is arranged in the first chamber 11 or the second chamber 12. The third liquid level detection component 31 and the fourth liquid level detection component are selectively electrically connected to detect whether the first chamber 11 reaches the second water full position.

[0066] The first liquid level detector 21 and the second liquid level detector 22 are located at different heights within the second chamber 12. When the body 202 is in the normal working position, the dirty liquid gradually increases primarily along the axial direction of the sewage tank body 15. When the dirty liquid in the second chamber 12 gradually increases until it submerges both the first liquid level detector 21 and the second liquid level detector 22, the dirty liquid acts as a conductor, electrically connecting the first liquid level detector 21 and the second liquid level detector 22, and connecting the electrical circuit between the first liquid level detector 21 and the second liquid level detector 22. At this point, it can be determined that the dirty liquid in the second chamber 12 has reached the first full water position, thereby sending a signal to the cleaning device 100 to control the start and stop of the suction device or change the power of the suction device, thereby preventing the dirty liquid from being sucked into the suction channel 172 provided in the second chamber 12, causing the dirty liquid to enter the undesirable structure inside the cleaning device 100 and causing failure risk.

[0067] In addition, the third liquid level detection member 31 and the fourth liquid level detection member are disposed at different locations within the sewage tank body 15. The third liquid level detection member 31 is disposed within the first chamber 11, and the fourth liquid level detection member can be disposed within either the first chamber 11 or the second chamber 12. When the body 202 is in the flat working position, the sewage tank body 15 tilts, and the sewage gradually increases primarily along the radial direction of the sewage tank body 15. The sewage in the first chamber 11 gradually increases until it submerges both the third liquid level detection member 31 and the fourth liquid level detection member. At this point, the sewage acts as a conductor, electrically connecting the third and fourth liquid level detection members 31 and 31, thereby establishing an electrical circuit between the third and fourth liquid level detection members. At this time, it can be known that the dirty liquid in the second chamber 12 has reached the second water full position, thereby sending a stop suction signal to the cleaning device 100, thereby avoiding the risk of failure caused by the dirty liquid being sucked into the suction channel 172 provided in the first chamber 11 and causing the dirty liquid to enter the unexpected structure inside the cleaning device 100.

[0068] Specifically, the fourth liquid level detection member and the first liquid level detection member 21 are constructed as an integrated liquid level detection member. This facilitates the reasonable regularization of the distribution position of the fourth liquid level detection member and the first liquid level detection member 21. Moreover, on the basis of being able to simultaneously form two water full position detection circuits, since the fourth liquid level detection member and the first liquid level detection member 21 are constructed as an integrated liquid level detection member, the fourth liquid level detection member and the first liquid level detection member 21 can also be used interchangeably to perform water full position detection, thereby ensuring the stability of the water full position detection operation.

[0069] Furthermore, in combination with Figures 5, 6 and 8, the first liquid level detection member 21 is arranged at the bottom of the second chamber 12; the second liquid level detection member 22 is arranged on the side wall or top of the second chamber 12; and the third liquid level detection member 31 is arranged on the side wall or top of the first chamber 11.

[0070] Among them, the first liquid level detection member 21 is arranged at the bottom of the second chamber 12, so that the first liquid level detection member 21 can be easily submerged by the dirty liquid, thereby forming the basis for the electrical conduction between the first water level detection component 20 and the second water level detection component 30; the second liquid level detection member 22 is arranged on the side wall or top of the second chamber 12, so that the dirty liquid in the second chamber 12 can be prevented from passing through the suction channel 172 provided in the second chamber 12 and entering the undesirable structure inside the cleaning device 100, while also increasing the capacity of the dirty liquid that the first water level detection component 20 can store in the second chamber 12 before issuing a stop suction signal; the third liquid level detection member 31 is arranged on the side wall or top of the first chamber 11, so that the dirty liquid in the first chamber 11 can not pass through the suction channel 172 provided in the first chamber 11 and enter the undesirable structure inside the cleaning device 100, while also increasing the capacity of the dirty liquid that the second water level detection component 30 can store in the first chamber 11 before issuing a stop suction signal.

[0071] 5-8 , a first conductive contact 181, a second conductive contact 182, and a third conductive contact 183 are provided on a side wall of the sewage tank body 15 facing the body 202. The first conductive contact 181 is connected to the first liquid level detecting member 21, the second conductive contact 182 is connected to the second liquid level detecting member 22, and the third conductive contact 183 is connected to the third liquid level detecting member 31.

[0072] Among them, the first conductive contact 181, the second conductive contact 182 and the third conductive contact 183 on the side wall of the sewage tank body 15 facing the fuselage 202 are electrically connected to the first liquid level detection component 21, the second liquid level detection component 22 and the third liquid level detection component 31, respectively. This can provide an electrical signal transmission channel for the first liquid level detection component 21, the second liquid level detection component 22 and the third liquid level detection component 31 to transmit liquid full information, thereby improving the scientificity and systematicity of the first water level detection component 20 and the second water level detection component 30 in detecting the liquid full signal.

[0073] Specifically, the micro switch is arranged at the rotating shaft between the body 202 and the floor brush 201 .

[0074] As shown in Figures 5 and 9, the sewage tank 10 further includes a suction grille disposed above the partition 16. The suction grille is provided with a first suction port and a second suction port spaced apart from each other. The second suction port is connected to the suction channel 172. In other words, the provision of both the first and second suction ports on the suction grille facilitates their arrangement and facilitates communication between the suction device and the first and second suction ports.

[0075] Furthermore, the suction grille is also connected to the suction device, that is, when the suction device is working, the suction device can extract air from the first suction port and the second suction port at the same time.

[0076] In addition, a filter sponge is also provided on the side of the suction grille towards the dividing plate 16. Specifically, the downside of the suction grille is provided with a mounting rib, and the filter sponge is installed on the mounting rib.

[0077] Furthermore, a connecting channel is provided on the partition 16, one end of the connecting channel is communicated with the second suction port, and the other end of the connecting channel is communicated with the suction channel 172. That is, the suction channel 172 is communicated with the second suction port through the connecting channel on the partition 16.

[0078] Furthermore, as shown in Figure 9, the partition 16 includes a first partition 161, a second partition 162, and a connecting plate 163. The connecting plate 163 is connected between the first and second partitions 161, 162. The suction grille is fixed to the first partition 161. A suction channel 172 is formed between the connecting plate 163 and the sewage tank 10. The second partition 162 is provided with a notch 164 that connects the second chamber 12 with the first chamber 11. In other words, the partition 16 is composed of the first partition 161, the second partition 162, and the connecting plate 163. The first chamber 11 is formed between the first and second partitions 161, 162, and the second chamber 12 is formed between the lower portion of the second partition 162 and the sewage tank 10. Furthermore, the suction grille is fixed to the first partition 161 and is provided with a suction hole that connects to the first suction port on the suction grille.

[0079] Furthermore, a suction channel 172 is formed between the connecting plate 163 and the sewage tank 10 , so that the structure of the connecting plate 163 can be fully utilized, and there is no need to provide an additional channel on the partition plate 16 to form the suction channel 172 .

[0080] In addition, a plurality of reinforcing ribs spaced apart in the upper and lower directions are provided on the side of the connecting plate 163 facing the sewage tank 10. The reinforcing ribs can, on the one hand, strengthen the connecting plate 163, and on the other hand, can block water and prevent the water in the second chamber 12 from entering the first suction port along the suction channel 172.

[0081] In addition, the first chamber 11 and the second chamber 12 are connected to each other via the notch 164 on the partition 16 , so that the sewage in the first chamber 11 can be guided into the second chamber 12 .

[0082] As shown in Figures 6 and 7, the sewage tank 10 further includes a filter element 19. The filter element 19 is disposed on the side of the second partition 162 facing the first partition 161 and connected to the second partition 162. The filter element 19 is in communication with the notch 164. Specifically, the filter element 19 is disposed within the first chamber 11 and upstream of the second partition 162. This ensures that dirt is filtered by the filter element 19 before flowing from the first chamber 11 to the second chamber 12. This removes larger particles of waste before the dirt is drawn from the first chamber 11 into the second chamber 12, thereby preventing blockage at the notch 164 in the second partition 162 (the connection between the first chamber 11 and the second chamber 12). This ensures smooth solid-liquid separation within the sewage tank 10 and prevents waste liquid from entering undesirable structures within the cleaning apparatus 100 (such as the suction device), which could lead to failure.

[0083] According to the second embodiment of the present disclosure, the cleaning device 100 includes: a floor brush 201, a body 202, a sewage tank 10, a suction device, a micro switch, and a controller. The body 202 is rotatably mounted on the floor brush 201. The body 202 has a normal working position and a flat working position relative to the floor brush 201. The inclination angle of the flat working position is lower than the inclination angle of the normal working position. It is understood that the floor brush 201 can clean the dirt by moving on the cleaning surface to pick up dirt attached during the movement. The body 202 is rotatably mounted on the floor brush 201, which makes it convenient for the user to clean low areas. The sewage tank 10 can store the dirty liquid after the floor brush 201 cleans the dirt.

[0084] In addition, according to the changes in the working environment of the cleaning device 100, the body 202 has a normal working position and a lying flat working position relative to the brush 201. The normal working position is the position of the body 202 shown in Figure 2. At this time, the inclination angle of the body 202 relative to the horizontal plane is at least 30°, such as 30°, 45°, 60° and 90°, etc. The user can clean the regular floor normally, and the user's body is generally in an upright or slightly bent state. The lying flat working position is the position of the body 202 shown in Figure 1. At this time, the inclination angle of the body 202 relative to the horizontal plane can be less than 15°, such as 0°, 3° and 5°, etc. The user can clean low areas (such as under the bed, the bottom of the cabinet and the bottom of the coffee table, etc.), and the user's body can be in a state of bending at a large angle. The body 202 can lower the overall height of the cleaning device 100 by lying flat, thereby adapting to the working environment when cleaning low areas, thereby improving the adaptability of the cleaning device 100 facing different working environments.

[0085] As shown in Figure 5, the sewage tank 10 is mounted on the body 202 and includes a first chamber 11 and a second chamber 12, which are interconnected. The first chamber 11 is a solid-liquid separation chamber, and the second chamber 12 is a waste liquid storage chamber, which are interconnected.

[0086] After the dirt on the cleaning work surface attached to the floor brush 201 is sucked into the solid-liquid separation chamber, the liquid in the dirt in the solid-liquid separation chamber is subjected to negative pressure from the connection between the solid-liquid separation chamber and the liquid-sucking chamber, and thus flows from the solid-liquid separation chamber to the liquid-sucking chamber. In this way, a step-by-step treatment effect can be achieved, in which the dirt is pre-collected in the solid-liquid separation chamber and then the solid-liquid separation of the dirt in the solid-liquid separation chamber is carried out, thereby reducing the risk of liquid-sucking entering undesirable structures within the cleaning device 100 and causing its failure.

[0087] The cleaning device 100 further includes a suction device, which is disposed above the sewage tank and is used to provide negative pressure.

[0088] The micro switch is arranged between the body 202 and the floor brush 201 or on one of them. When the body 202 is in the lying working position, the micro switch is triggered, and the controller is electrically connected to the micro switch. The micro switch is used to detect whether the body 202 reaches the lying working position, and the controller is used to adjust the pressure of the solid-liquid separation chamber and / or the dirty liquid holding chamber when the body 202 is in the lying working position.

[0089] That is, when the body 202 is nearly flat and the sewage tank 10 is tilted to a large extent, the distance between the horizontal surface of the sewage and the first suction port is short. If the suction device is still operated at the negative pressure of the solid-liquid separation chamber or the sewage holding chamber when the body 202 is in the normal cleaning state, the sewage may enter the suction device along with the airflow. Therefore, when the body 202 is tilted, it is necessary to adjust the negative pressure of the solid-liquid separation chamber or the sewage holding chamber to ensure that the sucked sewage or waste can be sucked into the sewage tank 10, and does not enter the suction device through the first suction port and the HEPA due to excessive suction force or splashing of liquid.

[0090] Specifically, by adjusting the negative pressure in the waste liquid holding chamber to be greater than the negative pressure in the solid-liquid separation chamber, even if the waste water cannot flow into the waste liquid holding chamber under the action of gravity due to the body 202 lying down, the waste water in the solid-liquid separation chamber can be caused to flow into the waste liquid holding chamber through the negative pressure, so that the body 202 can lie flat.

[0091] Therefore, when the body 202 is tilted, the micro switch is triggered, and the controller can adjust the negative pressure of the solid-liquid separation chamber or the dirty liquid holding chamber to ensure that the sucked dirty liquid or dirt can be sucked into the sewage tank 10, and will not enter the suction device through the first suction port and HEPA due to excessive suction force or liquid splashing.

[0092] As shown in Figure 5, a sewage tank 10 is provided with a sewage suction channel 13, which passes through the solid-liquid separation chamber and the sewage liquid holding chamber. The sewage suction channel 13 forms a sewage outlet 131 in the solid-liquid separation chamber. The upper end of the sewage tank 10 is provided with a first suction port. The sewage suction channel 13 connects the floor brush 201, the solid-liquid separation chamber and the suction device. When the cleaning device 100 starts cleaning, the interior of the solid-liquid separation chamber is pumped into a strong negative pressure environment under the action of suction. Under the strong negative pressure in the solid-liquid separation chamber, the sewage suction channel 13 draws the dirt on the floor brush 201 into the solid-liquid separation chamber through the sewage outlet 131 of the sewage suction channel 13, thereby completing the dirt collection work of the cleaning device 100 in advance.

[0093] In addition, a suction channel 172 is provided within the sewage tank 10. The suction channel 172 connects the sewage holding chamber and the suction device. The suction device drives airflow to draw suction from the sewage holding chamber, thereby driving sewage in the solid-liquid separation chamber into the sewage holding chamber. A controller is electrically connected to the suction device. After the microswitch is triggered, the controller adjusts the power of the suction device, thereby adjusting the negative pressure in the solid-liquid separation chamber or the sewage holding chamber. That is, one end of the suction channel 172 is connected to the first suction port, and the lower end of the suction channel 172 is connected to the sewage holding chamber. The connection between the suction channel 172 and the sewage holding chamber allows the negative pressure in the sewage holding chamber to be greater than the negative pressure in the solid-liquid separation chamber. Even if the sewage cannot flow into the sewage holding chamber due to gravity due to the body 202 being tilted, the negative pressure can still cause the sewage in the solid-liquid separation chamber to flow into the sewage holding chamber, thereby allowing the body 202 to lie flat.

[0094] Furthermore, the controller is electrically connected to the suction device, and after the micro switch is triggered, the controller adjusts the power of the suction device. That is, by adjusting the power of the suction device, the negative pressure of the solid-liquid separation chamber or the dirty liquid holding chamber can be adjusted.

[0095] Specifically, the duty cycle of the suction device first increases and then decreases. That is, when the housing 202 tilts to a certain degree, the microswitch on the rotating shaft closes. After receiving the signal indicating the microswitch is closed, the controller adjusts the power of the suction device. The power of the suction device first increases and then decreases. The power of the suction device after adjustment is less than the power before adjustment. This ensures that after the housing 202 tilts to a certain degree, sewage will not enter the first suction port of the sewage tank 10 along with the airflow.

[0096] Alternatively, the duty cycle of the suction device first decreases and then increases. That is, when the housing 202 tilts to a certain degree, the microswitch on the rotating shaft closes. The controller adjusts the power of the suction device after receiving the signal of the microswitch closure on the rotating shaft. The power of the suction device first decreases and then increases. The power of the suction device after adjustment is less than the power before adjustment. This ensures that after the housing 202 tilts to a certain degree, sewage will not enter the first suction port of the sewage tank 10 along with the airflow.

[0097] The cleaning device 100 also includes a first adjustment component, which is disposed at the sewage suction channel 13. The first adjustment component is used to adjust the cross-sectional area of ​​the sewage suction channel 13 to adjust the negative pressure in the solid-liquid separation chamber and the sewage holding chamber. Specifically, the negative pressure in the sewage holding chamber and the solid-liquid separation chamber can be adjusted by adjusting the diameter of the sewage suction channel 13. If the power of the suction device is not changed, the speed of the suction device is fixed. Reducing the cross-sectional area of ​​the sewage suction channel 13 between the suction device and the solid-liquid separation chamber will increase the negative pressure in the sewage holding chamber (increase the vacuum degree), and reduce the negative pressure in the solid-liquid separation chamber (decrease the vacuum degree).

[0098] The first adjustment assembly includes a first driving member and a first adjusting member. The first adjusting member is disposed in the sewage suction channel 13 and is a rotatable baffle. The first driving member drives the first adjusting member to rotate, thereby changing the cross-sectional area of ​​the sewage suction channel 13. Of course, the first adjusting member can also be other structures that can adjust the cross-sectional area of ​​the sewage suction channel 13.

[0099] The cleaning device 100 also includes a second adjustment component, which is disposed in the suction channel 172. The second adjustment component is used to adjust the cross-sectional area of ​​the suction channel 172 to adjust the negative pressure in the solid-liquid separation chamber and the waste liquid holding chamber. Specifically, the negative pressure in the waste liquid holding chamber and the solid-liquid separation chamber can be adjusted by adjusting the diameter of the suction channel 172. If the power of the suction device is not changed, the speed of the suction device is fixed. Increasing the cross-sectional area of ​​the suction channel 172 between the suction device and the waste liquid holding chamber will increase the negative pressure in the waste liquid holding chamber (increase the vacuum level) and reduce the negative pressure in the solid-liquid separation chamber (decrease the vacuum level).

[0100] The second adjustment assembly includes a second driving member and a second adjusting member. The second adjusting member is disposed in the suction channel 172 and is a rotatable baffle. The second driving member drives the second adjusting member to rotate, thereby changing the cross-sectional area of ​​the suction channel 172. Of course, the second adjusting member can also be other structures that can adjust the cross-sectional area of ​​the suction channel 172.

[0101] Specifically, as shown in Figures 4, 6, and 8, the sewage tank 10 also includes a first water level detection assembly 20 and a second water level detection assembly 30. The first water level detection assembly 20 detects the water level information of the solid-liquid separation chamber, and the second water level detection assembly 30 detects the water level information of the waste liquid holding chamber. The first water level detection assembly 20 is at least used to detect whether the waste liquid holding chamber has reached a first water-full position when the body 202 is in a normal working position. The second water level detection assembly 30 is at least partially located in the solid-liquid separation chamber and is at least used to detect whether the solid-liquid separation chamber has reached a second water-full position when the body 202 is in a flat working position. When the water level reaches the first water-full position, the first water level detection assembly 20 sends a stop suction signal, and when the water level reaches the second water-full position, the second water level detection assembly 30 sends a stop suction signal.

[0102] Furthermore, when the body 202 is in the normal working position, the first water level detection assembly 20 can detect whether the dirty liquid in the dirty liquid holding chamber has reached the first full water position. When the first full water position is reached, it sends a suction stop signal to the cleaning device 100. This avoids the risk of failure caused by dirty liquid being sucked into the suction channel 172 provided in the dirty liquid holding chamber and entering undesirable structures within the cleaning device 100.

[0103] When the body 202 is in the lying working position, the second water level detection component 30 can detect whether the dirty liquid in the solid-liquid separation chamber in this state has reached the second full water position. When the second full water position is reached, it sends a stop suction signal to the cleaning device 100. In this way, it is possible to avoid the risk of failure caused by the dirty liquid being sucked into the suction channel 172 provided in the solid-liquid holding chamber, causing the dirty liquid to enter the unexpected structure inside the cleaning device 100. Therefore, through the coordinated work of the first water level detection component 20 and the second water level detection component 30, it can be ensured that the dirty liquid in the dirty liquid holding chamber and the solid-liquid separation chamber will not be sucked into the unexpected structure, thereby improving the safety of the electronic components and the comprehensive practicality of the cleaning device 100 under different working conditions.

[0104] Therefore, by setting up the sewage tank 10, the water full level information when the body 202 is in the lying working position can be detected, thereby avoiding the problem of the cleaning device 100 failing when the sewage is sucked into its internal unwanted structure when in the lying working state.

[0105] Furthermore, the first water level detection component 20 and / or the second water level detection component 30 are electrically connected to the controller, and the controller controls the start and stop of the suction device according to the water level information of the detected first chamber 11 and / or the second chamber 12. The controller is respectively connected to the first water full detection component 20, the second water full detection component 30, and the suction device in the form of electrical signals. When the controller receives the stop suction signal from the first water full detection component 20 and the second water full detection component 30, it controls the suction device to stop working. In this way, the cleaning device 100 can complete the action of stopping suction after receiving the stop suction signal, so that the first water full detection component 20, the second water full detection component 30, the controller, and the suction device form a functionally coherent overall system, thereby improving the scientificity and systematicity of the cleaning device 100 when performing cleaning work.

[0106] Furthermore, after receiving the information that the body 202 is in the flat working position, the detection information of the second water full detection component 30 is confirmed. When the controller receives the information that the body 202 is in the flat working position, it first confirms the detection information of the second water full detection component 30. This ensures that when the cleaning device 100 is in the flat working position, it can also ensure that no sewage enters the undesirable structure inside the cleaning device 100.

[0107] According to the third aspect of the present disclosure, a method for controlling a cleaning device 100 includes:

[0108] In response to a start instruction for the cleaning device, the liquid level information of the first chamber 11 and / or the second chamber 12 is acquired, and the operation of the suction device is controlled according to the liquid level information.

[0109] The liquid level information of the first chamber 11 and / or the second chamber 12 is obtained, that is, whether the first water level detection component 20 and the second water level detection component 30 are triggered is determined.

[0110] If the first water level detection assembly 20 and / or the second water level detection assembly 30 is triggered, the suction device is shut down. In other words, when either the second chamber 12 or the first chamber 11 detects that it is full of water, the suction device is shut down, thereby effectively preventing the sewage in the first chamber 11 from entering the suction device through the suction port along with the airflow when the device is turned on.

[0111] If neither the first water level detection assembly 20 nor the second water level detection assembly 30 is triggered, the suction device is activated. In other words, the suction device is activated only when neither the second chamber 12 nor the first chamber 11 detects that the water is full, thereby preventing sewage from entering the suction device along with the air flow when the device is turned on.

[0112] In addition, the control method further includes: in response to a start instruction for the cleaning device 100 to operate, obtaining the degree of inclination of the body 202 relative to the brush 201 .

[0113] Controlling the operation of the suction device according to the liquid level information includes: controlling the operation of the suction device according to the liquid level information and the degree of inclination.

[0114] That is, when the user turns on the cleaning device 100, the body 202 may be in a tilted state, and the controller determines whether the micro switch is triggered. That is, when the body 202 tilts to a certain extent, the micro switch at the shaft is closed, and the controller receives a signal indicating that the micro switch at the shaft is closed.

[0115] If the microswitch is triggered, the controller adjusts the negative pressure in the first chamber 11 or the second chamber 12. That is, upon receiving the signal from the microswitch at the shaft being closed, the controller adjusts the negative pressure in the second chamber 12 and the first chamber 11, increasing the vacuum level in the second chamber 12 and decreasing the vacuum level in the first chamber 11, without changing the power of the suction device.

[0116] Furthermore, increasing the negative pressure in the second chamber 12 will increase the tendency of sewage to flow from the first chamber 11 to the second chamber 12, which is conducive to the separation of sewage and solid waste. Sewage will not be accumulated in the first chamber 11, and the sewage in the first chamber 11 will not be dumped close to the first suction port due to the fuselage 202, causing the sewage to enter the suction device together with the suction airflow.

[0117] In this way, the operation of the suction device is controlled based on the liquid level information and the degree of tilt. That is, the operation of the suction device is controlled in combination with the liquid level information and the degree of tilt. For example, if the liquid level information indicates a low liquid level and the tilt of the body 202 is low, the suction device can be controlled to operate normally. If the liquid level information indicates a high liquid level and the tilt of the body 202 is high, the suction device can be controlled to stop operating or its duty cycle can be reduced.

[0118] According to the control method of the cleaning device 100 of the fourth embodiment of the present disclosure, the method includes: adjusting the power of the suction device in response to the micro switch or the detection member being triggered.

[0119] That is, when the user turns on the cleaning device 100, the body 202 may be in a tilted state, and the controller determines that the micro switch is triggered, and then adjusts the power of the suction device. In other words, by adjusting the power of the suction device, the negative pressure of the first chamber 11 or the second chamber 12 can be adjusted.

[0120] Specifically, the duty cycle of the suction device can be increased first and then decreased. That is, when the housing 202 tilts to a certain degree, the microswitch on the rotating shaft closes. The controller adjusts the power of the suction device after receiving the signal of the microswitch closure on the rotating shaft. The power of the suction device first increases and then decreases. The power of the suction device after adjustment is less than the power before adjustment. This ensures that after the housing 202 tilts to a certain degree, sewage will not enter the first suction port of the sewage tank 10 along with the airflow.

[0121] Alternatively, the duty cycle of the suction device can be first decreased and then increased. That is, when the housing 202 tilts to a certain degree, the microswitch on the rotating shaft closes. The controller adjusts the power of the suction device after receiving the signal of the microswitch closure on the rotating shaft. The power of the suction device first decreases and then increases. The power of the suction device after adjustment is less than the power before adjustment. This ensures that after the housing 202 tilts to a certain degree, sewage will not enter the first suction port of the sewage tank 10 along with the airflow.
