Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and particularly relates to a control method for a cleaning device. Background Art

[0002] With the improvement of people's living standards, cleaning devices have been widely used in people's lives. Specifically, a cleaning device generally includes a body and a floor brush assembly pivotally connected to the body. The floor brush assembly includes a cleaning member and a dirt suction port. The cleaning member is used to clean a surface to be cleaned such as the ground. The body includes a fan, a dirt suction channel, and a sewage bucket communicated with the dirt suction channel. The dirt suction port is communicated with the dirt suction channel. When the cleaning device is working, the cleaning member cleans the surface to be cleaned, and at the same time, the fan cooperates with the cleaning member to suck the sewage formed after cleaning into the sewage bucket through the dirt suction port and the dirt suction channel. The above process is continuously carried out until the cleaning device completes the cleaning work.

[0003] In the prior art, when the cleaning device receives a shutdown instruction, the cleaning member will immediately stop rotating, and then the fan will be turned off after a certain delay. Among them, the purpose of delaying the shutdown of the fan is to enable the fan to suck the sewage in the dirt suction channel into the sewage bucket, so as to avoid the presence of sewage residues in the dirt suction channel when the cleaning device stops working. The remaining sewage flows along the dirt suction channel to the ground under the action of gravity and finally flows out of the cleaning device to cause secondary pollution to the already cleaned surface.

[0004] However, in the above method, since the cleaning member will immediately stop rotating when receiving the shutdown instruction, this causes the cleaning member to fit with the surface to be cleaned to form an almost airtight end face. In this case, there is no air circulation in the dirt suction channel, which results in that even if the fan is turned to the maximum gear, all the remaining sewage in the dirt suction channel cannot be sucked into the sewage bucket. Eventually, even if the fan is delayed in turning off after the cleaning device stops, it cannot effectively collect all the remaining sewage in the dirt suction channel, and some sewage will still flow onto the already cleaned surface under the action of gravity, causing secondary pollution. Summary of the Invention

[0005] The purpose of the embodiment of the present application is to provide a control method for a cleaning device, which effectively avoids the problem that the residual sewage in the dirt suction channel flows onto the surface to be cleaned after the cleaning device is shut down, causing secondary pollution, and fully improves the user experience.

[0006] The present application provides a control method for a cleaning device.

[0014] In one embodiment, after the controller receives the stop instruction, the control method of the cleaning device includes:

[0015] It controls the running state of the floor brush to prevent the floor brush from displacing.

[0016] In one embodiment, after the controller receives the stop instruction, the control method of the cleaning device further includes:

[0017] It judges whether the body of the cleaning device is in an upright state;

[0018] If the body of the cleaning device is in a non-upright state, it controls the running state of the floor brush to move the floor brush backward, so that the body of the cleaning device changes from the non-upright state to the upright state; wherein, the floor brush is subjected to a first traction force moving backward;

[0019] If the body of the cleaning device is in an upright state, it controls the running state of the floor brush to prevent the floor brush from displacing.

[0020] In one embodiment, a boosting unit is further provided on the floor brush. Controlling the running state of the floor brush to prevent the floor brush from displacing includes:

[0021] It controls the cleaning component and the boosting unit to rotate in opposite directions;

[0022] Wherein, the rotation of the cleaning component generates a second traction force, and the rotation of the boosting unit generates a third traction force. The magnitudes of the second traction force and the third traction force are equal, and the directions are opposite.

[0023] In one embodiment, a boosting unit is further provided on the floor brush. Controlling the running state of the floor brush to move the floor brush backward includes:

[0024] It controls the cleaning component to rotate in a first direction; wherein, the first traction force is generated by the rotation of the cleaning component;

[0025] Alternatively,

[0026] control the cleaning member to rotate in a second direction and control the assisting unit to rotate in a third direction; wherein, the second direction and the third direction are the same or opposite, the rotation of the cleaning member generates a fourth traction force, the rotation of the assisting unit generates a fifth traction force, and the first traction force is formed by the superposition of the fourth traction force and the fifth traction force.

[0027] In one embodiment, the control method of the cleaning device further includes:

[0028] If the fuselage is in an upright state, control the dirt suction assembly to operate at a first power;

[0029] If the fuselage is in a non-upright state, control the dirt suction assembly to operate at a second power; wherein, the second power is less than or equal to the first power.

[0030] In one embodiment, the control method of the cleaning device further includes:

[0031] If the rotation duration of the cleaning member reaches a first preset duration, control the cleaning member and the assisting unit to stop rotating simultaneously.

[0032] In one embodiment, the control method of the cleaning device further includes:

[0033] When the fuselage is in an upright state, the rotation speed of the cleaning member is less than or equal to the rotation speed of the cleaning member when the cleaning device performs a cleaning operation before receiving a stop instruction.

[0034] The present application provides a control method for a cleaning device, which is applied to a cleaning device. The cleaning device includes a fuselage and a floor brush. The fuselage is pivotally connected to the floor brush. A cleaning member is provided on the floor brush. A dirt suction assembly for adsorbing dirt and a controller for controlling the cleaning member and the dirt suction assembly are provided inside the fuselage. The specific control method is that during the cleaning operation of the cleaning device, if the controller receives a stop instruction, control the cleaning member to delay operation for a first preset duration, and control the dirt suction assembly to delay operation for a second preset duration.

[0035] It can be seen from this that in the present application, when a shutdown instruction is received, the controller will control the cleaning member and the sewage suction assembly to operate with a time delay for a period of time. On the one hand, the cleaning member is turned off with a time delay to assist the sewage suction assembly in sucking sewage, promoting the formation of a flowable air passage between the sewage suction passage and the external environment, so that the sewage remaining in the sewage suction passage is collected into the sewage bucket. On the other hand, when a shutdown instruction is received, there may still be sewage remaining on the cleaning member. By turning off the cleaning member with a time delay, the cleaning member continues to rotate, separating the sewage on the cleaning member. At the same time, after separation, the sewage suction assembly is used to suck the sewage into the sewage bucket, cleaning the cleaning member and avoiding the sewage on the cleaning member being left on the ground to cause secondary pollution. Secondly, the cleaning member that is turned off with a time delay causes the sewage that has not been sucked into the sewage bucket by the sewage suction assembly to be adsorbed by the rotating cleaning member during the process of flowing towards the sewage suction port under the action of gravity, and will not fall to the ground to pollute the ground. The sewage suction assembly is turned off with a time delay and cooperates with the rotation of the cleaning member to suck the sewage remaining in the sewage suction passage, avoiding sewage overflow and polluting the ground. Therefore, the present application effectively avoids the residual sewage in the sewage suction passage flowing onto the surface to be cleaned after the cleaning device is shut down, and fully improves the user experience.

Detailed implementation manners

[0050] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0051] Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0052] Please refer to Figure 1 which is a schematic structural diagram of the cleaning device 1 provided by an embodiment of the present application. Please refer to Figure 2 which is a schematic connection diagram of the controller 40 provided by an embodiment of the present application. As Figure 1As shown in the figure, the cleaning device 1 in the present application includes a body 10 and a floor brush 20 pivotally connected to the body 10. The floor brush 20 is provided with a cleaning member 230 and an assisting unit 210; the cleaning member 230 is rotatably arranged on the floor brush 20 and is used for cleaning the surface to be cleaned on the ground; the assisting unit 210 is rotatably arranged on the floor brush 20 to reduce the friction between the floor brush 20 and the ground, so that when the user holds the cleaning device 1 to clean the surface to be cleaned, it is more labor-saving. Exemplarily, the assisting unit 210 can be a crawler or a supporting wheel, etc. Further, the assisting unit 210 can be a supporting wheel with a driving motor. According to the moving direction of the floor brush 20, the driving motor drives the assisting unit 210 to rotate to provide the floor brush 20 with an assisting force in the same direction as its moving direction, thereby saving labor for the user and making the operation convenient. The assisting unit 210 can also be a supporting wheel, and the diameter of the supporting wheel is greater than or equal to the diameter of the cleaning member 230 to provide a supporting force for the floor brush 20. The cleaning member 230 can be a crawler-type cleaning member 230 or a roller brush-type cleaning member 230; when the cleaning member 230 is a roller brush-type cleaning member 230, one roller brush or multiple roller brushes can be arranged on the floor brush 20, and according to the number of roller brushes, a single-roller cleaning mode or a multi-roller cleaning mode is formed. The body 10 is provided with a dirt suction assembly 110 and a controller 40; the dirt suction assembly 110 is used for adsorbing the dirt on the surface to be cleaned; as Figure 2 shown in the figure, the controller 40 is connected to the cleaning member 230, the assisting unit 210 and the dirt suction assembly 110. The controller 40 is used for identifying the operating state of the cleaning device 1 and controlling the operating states of the cleaning member 230, the assisting unit 210 and the dirt suction assembly 110. Exemplarily, the dirt suction assembly 110 can be a blower.

[0053] As Figure 1 shown in the figure, a handle assembly 120 is formed on the body 10, and the user can operate the cleaning device 1 by holding the above handle assembly 120. The handle assembly 120 is provided with a selection button 121 for operating the cleaning device 1. A trigger switch 30 is arranged on the floor brush 20, and the trigger switch 30 can be used to detect the posture of the body 10. A sewage bucket is arranged on the body 10. A dirt suction port is arranged at the bottom surface of the floor brush 20 near the cleaning member 230. A dirt suction channel 220 communicating with the above dirt suction port is arranged in the floor brush 20, and the dirt suction channel 220 extends all the way to the inside of the body 10 and communicates with the sewage bucket. In addition, a water tank is arranged on the body 10, and the water tank is used for supplying water to the cleaning member 230.

[0054] When performing a cleaning operation, the body 10 is in an inclined state. Under the control of the controller 40, the sewage suction assembly 110 and the cleaning member 230 operate, and the controller 40 controls the water tank to supply liquid to the cleaning member 230. During the rotation of the wet cleaning member 230, stains on the surface to be cleaned are removed by physical friction with the surface to be cleaned. Further, the sewage suction assembly 110 operates to generate a suction force. Dirt adhering to the cleaning member 230 or the surface to be cleaned is drawn into the sewage suction channel 220 through the sewage port under the action of the suction force of the sewage suction assembly 110 and is finally stored in the sewage bucket. The above process is continued until the cleaning of the surface to be cleaned is completed.

[0055] Please refer to Figure 3 , which is a schematic structural diagram of the controller 40 provided by an embodiment of the present application. As Figure 3 shown, the controller 40 includes at least one processor 43 and a memory 41. Figure 3 Here, one processor 43 is taken as an example. The processor 43 and the memory 41 are connected through a bus 42. The memory 41 stores instructions executable by the processor 43. When the instructions are executed by the processor 43, the controller 40 can execute all or part of the processes of the methods in the following embodiments.

[0056] The memory 41 can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic memory, flash memory, magnetic disk or optical disk.

[0057] The present application also provides a computer-readable storage medium storing a computer program executable by the processor 43 to complete the control method of the cleaning device 1 provided in the following embodiments of the present application.

[0058] Please refer to Figure 4 , which is a schematic flow diagram of the control method of the cleaning device 1 provided by an embodiment of the present application. This method can be executed by the controller 40 shown in Figure 3 . This method includes the following steps S210 - step S220.

[0059] Step S210: During the cleaning operation of the cleaning device 1, if the controller 40 receives a shutdown instruction, it controls the cleaning member 230 to run for a first preset duration with a time delay.

[0060] In this step, when the cleaning device 1 receives a cleaning instruction, it can perform a cleaning operation on the surface to be cleaned. Specifically, a selection button 121 can be provided on the body 10. The user can make the cleaning device 1 operate in a corresponding mode by triggering the selection button 121, so as to clean the surface to be cleaned. Exemplarily, the selection button 121 can be a hardware button, or a touch screen is provided on the body 10, and the selection button 121 is a touch button provided on the touch screen.

[0061] During the cleaning operation of the cleaning device 1, the controller 40 monitors in real time whether a shutdown instruction is received. Specifically, the user can send a shutdown instruction to the controller 40 by triggering the selection button 121. Or, the state of the body 10 can be monitored. When it is detected that the state of the body 10 is the upright state as shown in Figure 1 When the controller 40 considers that a shutdown instruction has been received. Exemplarily, the trigger switch 30 can monitor the state of the body 10 and feed it back to the controller 40. When it is detected that the body 10 is in the upright state as shown in Figure 1 When the trigger switch 30 can send a monitoring signal to the controller 40. When the controller 40 receives this monitoring signal, it is considered that a shutdown instruction has been received by default.

[0062] It should be noted that as shown in Figure 5 When the cleaning device 1 performs a cleaning operation, the user needs to hold the cleaning device 1. Specifically, the user holds the handle assembly 120 on the cleaning device 1 and pushes the floor brush 20 to move by manipulating the handle assembly 120, so as to realize the cleaning of the surface to be cleaned passed by the floor brush 20. When the controller 40 detects that the body 10 changes from the upright state as shown in Figure 1 To the upright state as shown in Figure 5Automatically power on when in the non-erect state as shown. Alternatively, a selection button 121 is provided on the handle assembly 120 of the body 10. The selection button 121 includes a power-on / off button, and the power-on / off button can be a mechanical button or a touch screen button or any other form of trigger button. When the user presses the power-on / off button and the body 10 is in the erect state, the cleaning device 1 powers on and can perform cleaning operations. After the cleaning device 1 powers on, it moves under the user's manipulation, and the cleaning member 230 rotates to clean the surface to be cleaned. Further, during the cleaning process, the assisting unit 210 can provide assistance in the same direction as the movement trend of the floor brush 20 for the floor brush 20 according to the movement direction of the floor brush 20, saving the user's effort. During the cleaning operation of the cleaning device 1, the user can operate the cleaning device 1 at any time to stop the cleaning operation and power off. The user can power off the cleaning device 1 by restoring the body 10 from the non-erect state to the erect state or by operating the power-on / off button on the body 10. Therefore, when it is detected that the body 10 is in the erect state or the power-on / off button is triggered, the controller 40 can consider that it has received a shutdown instruction.

[0063] Further, when the controller 40 monitors that it has received a shutdown instruction, it controls the cleaning member 230 to continue operating. After monitoring that the operating duration of the cleaning member 230 reaches a first preset duration, it controls the cleaning member 230 to stop operating. Exemplarily, the first preset duration can be 20 - 60 s.

[0064] Step S220: Control the sewage suction assembly 110 to operate with a time delay for a second preset duration.

[0065] In this step, after the controller 40 receives a shutdown instruction, it can control the sewage suction assembly 110 to continue operating. After monitoring that the operating duration of the sewage suction assembly 110 reaches a second preset duration, it controls the sewage suction assembly 110 to stop operating. Exemplarily, the second preset duration can be 20 - 80 s.

[0066] It can be seen from this that in this application, when receiving a shutdown instruction, the controller 40 will control the cleaning member 230 and the sewage suction assembly 110 to operate with a time delay for a period of time, so as to ensure that an air-circulating channel can be formed between the atmosphere and the sewage suction channel 220 during the operation of the cleaning member 230. Then, on the basis of ensuring the formation of the above-mentioned circulation channel, the sewage suction resistance of the sewage suction assembly 110 is reduced to ensure that the sewage suction assembly 110 can absorb the residual sewage in the sewage suction channel 220 into the sewage bucket. Effectively avoid the residual sewage in the sewage suction channel 220 flowing onto the surface to be cleaned after the cleaning device 1 shuts down, and fully improve the user's experience.

[0067] Further, when a shutdown instruction is received, there may still be stains remaining at the place where the cleaning member 230 contacts the surface to be cleaned. In the above embodiments, by delaying the shutdown of the cleaning member 230, the cleaning member 230 continues to rotate to clean up the remaining stains, thus fully improving the cleaning effect. Exemplarily, for the crawler-type cleaning member 230, its width is relatively long, and when a cleaning instruction is received, there is likely to be a situation where stains remain at the place where the cleaning member 230 contacts the surface to be cleaned. In the above embodiments, by delaying the shutdown of the cleaning member 230, this problem can be effectively solved.

[0068] Furthermore, when a shutdown instruction is received, there may still be dirt remaining on the cleaning member 230. By delaying the shutdown of the cleaning member 230, the cleaning member 230 continues to rotate, and then the scraping strip provided on the floor brush 20 is used to strip the dirt on the cleaning member 230. At the same time, after the stripping, the dirt is sucked into the sewage bucket by the sewage suction assembly 110. In this way, the dirt on the cleaning member 230 is cleaned, improving the cleanliness of the cleaning member 230.

[0069] In one embodiment, when a shutdown instruction is received, the controller 40 can control the cleaning member 230 and the sewage suction assembly 110 to operate with a time delay through the following scheme:

[0070] Scheme 1: When a shutdown instruction is received, the controller 40 can control the cleaning member 230 and the sewage suction assembly 110 to operate simultaneously.

[0071] Scheme 2: When a shutdown instruction is received, the controller 40 can first control the cleaning member 230 to operate, and then after a period of time, control the cleaning member 230 and the sewage suction assembly 110 to operate simultaneously.

[0072] In this way, the cleaning member 230 operates with a time delay first. A scraping strip that is interference-fitted with the cleaning member 230 can also be provided on the floor brush. As the cleaning member 230 rotates, the scraping strip is used to strip the dirt on the cleaning member 230 from the cleaning member 230. At the same time, the rotation of the cleaning member 230 is used to remove the remaining stains on the surface to be cleaned. After a period of time, the sewage suction assembly 110 is turned on to efficiently concentrate and absorb the above-mentioned dirt into the sewage bucket, further ensuring the cleaning effect. In addition, the residual sewage in the sewage suction channel 220 may be in the shape of water droplets. Delaying the activation of the sewage suction assembly 110 can cause the water droplet-shaped residual sewage to gather, enabling the sewage suction assembly 110 to better suck out the sewage in the sewage suction channel 220, further improving the water absorption effect on the sewage in the sewage suction channel 220 and effectively avoiding the phenomenon of sewage residue.

[0073] Scheme 3: When a shutdown instruction is received and it is monitored that the cleaning member 230 and the sewage suction assembly 110 have run for a period of time, the cleaning member 230 and the sewage suction assembly 110 are turned off simultaneously.

[0074] Specifically, combining Solution 1 and Solution 3 can obtain a solution where when a shutdown instruction is received, the cleaning component 230 and the sewage suction assembly 110 are simultaneously turned on and off. At this time, the running duration of the cleaning component 230, i.e., the first preset duration, is equal to the total running duration of the sewage suction assembly 110, i.e., the second preset duration.

[0075] Combining Solution 2 and Solution 3 can obtain a solution where when a shutdown instruction is received, the controller 40 controls the cleaning component 230 to turn on first, and after a period of time, the sewage suction assembly 110 is turned on. Then, after a period of time, the cleaning component 230 and the sewage suction assembly 110 are simultaneously turned off. At this time, the total running duration of the cleaning component 230, i.e., the first preset duration, is greater than the total running duration of the sewage suction assembly 110, i.e., the second preset duration.

[0076] Solution 4: When a shutdown instruction is received and it is monitored that the running duration of the cleaning component 230 reaches the first preset duration, the cleaning component 230 is turned off. After a delay for a period of time, the sewage suction assembly 110 is turned off.

[0077] By the above measures, the cleaning component 230 is turned off first, and then the sewage suction assembly 110 is turned off after a delay, enabling the sewage suction assembly 110 to suck the residual sewage in the sewage suction channel 220 into the sewage bucket as much as possible, fully avoiding the situation of sewage residue in the sewage suction channel 220.

[0078] Combining Solution 4 and Solution 1 can obtain a solution where when a shutdown instruction is received, the cleaning component 230 and the sewage suction assembly 110 are simultaneously turned on. Then, when the running duration of the cleaning component 230 reaches the first preset duration, the cleaning component 230 is turned off. When it is monitored that the running duration of the sewage suction assembly 110 reaches the second preset duration, the sewage suction assembly 110 is turned off. At this time, the total running duration of the cleaning component 230, i.e., the first preset duration, is less than the total running duration of the sewage suction assembly 110, i.e., the second preset duration.

[0079] Combining Solution 4 and Solution 2 can obtain a solution where when a shutdown instruction is received, the controller 40 controls the cleaning component 230 to turn on first, and after a period of time, the sewage suction assembly 110 is turned on. Then, after a period of time, the cleaning component 230 is turned off first, and then the sewage suction assembly 110 is turned off after a delay. At this time, the total running duration of the cleaning component 230, i.e., the first preset duration, can be less than, greater than, or equal to the total running duration of the sewage suction assembly 110, i.e., the second preset duration.

[0080] Solution 5: When a shutdown instruction is received and it is monitored that the running duration of the sewage suction assembly 110 reaches the second preset duration, the sewage suction assembly 110 is turned off. After a delay for a period of time, the cleaning component 230 is turned off.

[0081] In order to facilitate the pivotal connection between the body 10 and the floor brush 20, the sewage suction channel 220 located at the pivotal connection is usually designed as a specific structure such as a threaded structure. Further, the sewage suction channel 220 at the pivotal connection between the body 10 and the floor brush 20 is a threaded hose. The threaded hose is provided with folds at many places, which is easy to hide dirt. Due to the insufficient power of the sewage suction component 110 or the structural limitation of the above-mentioned sewage suction channel 220, the sewage near the sewage suction port in the sewage suction channel 220 cannot be sucked into the sewage bucket, and finally flows out to the ground along the sewage suction port. To this end, in order to solve the above-mentioned problem, in this embodiment, the cleaning member 230 is closed with a delay, so that the dirt in the sewage suction channel 220 can be absorbed by the rotating cleaning member 230 when it escapes from the sewage suction port through the sewage suction channel 220. Alternatively, when the dirt flows from the sewage suction channel 220 to the ground, the rotating cleaning member 230 can absorb the dirt flowing to the ground, thereby avoiding the dirt being retained on the surface that has been cleaned to cause secondary pollution.

[0082] The fifth solution is combined with the first solution to obtain a solution in which, when receiving the shutdown command, the controller 40 turns on the cleaning member 230 and the dirt suction assembly 110 at the same time, and then turns off the dirt suction assembly 110 when it is detected that the running time of the dirt suction assembly 110 reaches the second preset time, and then turns off the cleaning member 230 after a delay. At this time, the total running time of the cleaning member 230, i.e., the first preset time, is greater than the total running time of the dirt suction assembly 110, i.e., the second preset time.

[0083] The fifth scheme is combined with the second scheme to obtain a scheme in which, when a shutdown command is received, the controller 40 controls the cleaning member 230 to start first, and then starts the dirt suction assembly 110 after a period of time, and then monitors that the running time of the dirt suction assembly 110 reaches the second preset time, and then turns off the dirt suction assembly 110, and then turns off the cleaning member 230 after a delay. At this time, the total running time of the cleaning member 230, that is, the first preset time, is greater than the total running time of the dirt suction assembly 110, that is, the second preset time.

[0084] It can be seen that in the above embodiments, the delayed operation of the cleaning member 230 and the dirt suction assembly 110 is controlled by different control methods, which achieves different cleaning effects. The methods are flexible and changeable, but they are all easy to control.

[0085] In one embodiment, when the controller 40 executes the above step S210 and receives a stop instruction, it also controls the power assist unit 210 to rotate.

[0086] In this embodiment, after receiving the shutdown instruction, the cleaning member 230 shuts down with a delay. During the rotation of the cleaning member 230, the floor brush 20 is subjected to the traction force generated by the rotation of the cleaning member 230. In order to control the movement state of the floor brush 20 so that the floor brush 20 moves backward to clean the dirt that may remain on the ground, which is convenient for the user to store, or the floor brush 20 is relatively stationary on the ground without displacement to reduce the force required for the user to hold the cleaning device. A boosting unit 210 is provided on the floor brush 20, and the controller 40 will control the boosting unit 210 and the cleaning member 230 to rotate simultaneously, so that the boosting unit 210 and the cleaning member 230 form a rotational cooperation to control the running state of the floor brush 20. Specifically, the principle of controlling the running state of the floor brush 20 is as follows: The boosting unit 210 and the cleaning member 230 will apply corresponding traction forces to the floor brush 20 during the rotation process, and based on the magnitude of the above traction forces, the running state of the floor brush 20 is controlled.

[0087] The following details the working principle of controlling the movement state of the floor brush 20:

[0088] (1) The cleaning member 230 and the boosting unit 210 rotate simultaneously to control the running state of the floor brush 20 so that the floor brush 20 does not move.

[0089] In this embodiment, during the rotation of the cleaning member 230 and the boosting unit 210, a traction force F 11 and F 12 are applied to the floor brush 20, and F 11 and F 12 are both applied to the floor brush 20, and the magnitudes of F 11 and F 12 are equal and the directions are opposite. The floor brush 20 can be non-displaced under the superposition of the above F 11 and F 12 .

[0090] By the above measures, when receiving the shutdown instruction, the running states of the cleaning member 230 and the boosting unit 210 are controlled so that the floor brush 20 does not move, and the cleaning device 1 no longer moves after shutdown, which greatly facilitates the user to manage the cleaning device 1.

[0091] (2) The cleaning member 230 and the boosting unit 210 rotate simultaneously to control the running state of the floor brush 20 so that the floor brush 20 moves backward.

[0092] In this embodiment, during the rotation of the cleaning member 230 and the boosting unit 210, a traction force F 21 and F 22 are generated, and the traction forces F 21 and F 22 are both applied to the floor brush 20. Among them, the traction forces F 21 and F 22Superposition generates a first traction force F, and the direction of the first traction force F is the same as that Figure 6 indicated by the arrow in, and under the action of the first traction force F, the floor brush 20 moves Figure 6 in the direction indicated by the arrow in.

[0093] For some cleaning devices 1, they do not have the function of standing upright and shutting down, that is, when the body 10 is restored from a non-standing upright state to a standing upright state, the cleaning device 1 does not shut down. In this case, the user must trigger the power on / off button on the handle to shut down the cleaning device 1. After that, since the body 10 is in an inclined state when the cleaning device 1 is performing the cleaning operation, for the convenience of storage, the user needs to manually change the body 10 from a non-standing upright state to a standing upright state after shutting down. In the above embodiment, when receiving the shutdown instruction, by controlling the running state of the floor brush 20, the floor brush 20 moves backward, reducing the resistance when the body 10 becomes a standing upright state, assisting the user, and enabling the user to more conveniently restore the body 10 to a standing upright state.

[0094] In addition, the sewage suction channel 220 at the pivot connection between the body 10 and the floor brush 20 is a threaded hose. There are many folds in the threaded hose, which are prone to dirt accumulation. Due to insufficient power of the sewage suction component 110 or the structural limitation of the above sewage suction channel 220, the sewage near the sewage suction port in the sewage suction channel 220 cannot be sucked into the sewage bucket and finally flows out to the ground along the sewage suction port. In this embodiment, by controlling the running state of the floor brush 20, the floor brush 20 moves backward, enabling the cleaning part 230 to adsorb the dirt flowing onto the ground, effectively avoiding secondary pollution caused by dirt remaining on the already cleaned surface.

[0095] In one embodiment, when the controller 40 executes the above step S210 and receives the control instruction, the following steps will also be executed:

[0096] Judge whether the body 10 is in a standing upright state, and thus perform different operations based on the judgment result.

[0097] In this embodiment, when the controller 40 receives the shutdown instruction, it will judge whether the body 10 is in a standing upright state as Figure 1 shown. Specifically, the judgment method can be that the trigger switch 30 detects the state of the body 10. When it detects that the body 10 is in a standing upright state as Figure 1 shown, the trigger switch 30 can send a monitoring signal to the controller 40. When the controller 40 receives the above monitoring signal, it can determine that the body 10 is in a standing upright state. Further, when the controller 40 does not receive the above monitoring signal, it can determine that the body 10 is in a non-standing upright state. Further, the trigger switch 30 can be a mechanical structure provided on the floor brush 20 or a micro switch provided on the body 10.

[0098] After determining the state of the fuselage 10, the controller 40 can perform different operations according to the judgment result. The specific operation principle is explained in detail below:

[0099] ① If the controller 40 monitors that the fuselage 10 is in an upright state, it can control the running state of the floor brush 20 so that the floor brush 20 does not move.

[0100] In one embodiment, the controller 40 can control the running state of the floor brush 20 so that the floor brush 20 does not move in the following manner:

[0101] Control the cleaning member 230 and the assisting unit 210 to rotate in two opposite directions; wherein, the rotation of the cleaning member 230 generates a second traction force, and the rotation of the assisting unit 210 generates a third traction force. The magnitudes of the second traction force and the third traction force are equal, and the directions are opposite. Specifically, when the cleaning member 230 rotates in the clockwise direction, the assisting unit 210 can rotate in the counterclockwise direction; or, when the cleaning member 230 rotates in the counterclockwise direction, the assisting unit 210 can rotate in the clockwise direction; or, the cleaning member 230 can rotate in an alternating manner of clockwise and counterclockwise. Correspondingly, at this time, the assisting unit 210 also needs to rotate in an alternating manner of clockwise and counterclockwise.

[0102] Exemplarily, as Figure 7 shown, when the controller 40 detects that the fuselage 10 is in an upright state, it can control the cleaning member 230 to rotate in the clockwise direction as shown in Figure 7 , at this time, the cleaning member 230 generates a second traction force F as shown in Figure 7 ; at the same time, the controller 40 can control the assisting unit 210 to rotate in the counterclockwise direction as shown in 5 ; at this time, the assisting unit 210 generates a third traction force F as shown in Figure 7 , at this time, the third traction force F as shown in Figure 7 is generated. The second traction force F 4 and the third traction force F 4 are equal in magnitude and opposite in direction, and both are applied to the floor brush 20. At this time, under the superposition of the above two traction forces, the floor brush 20 can not move. 5

[0103] In one embodiment, when it is monitored that the rotation duration of the cleaning member 230 reaches the first preset duration, the controller 40 can control the cleaning member 230 and the assisting unit 210 to stop rotating.

[0104] Through the above measures, when it is monitored that the fuselage 10 is in an upright state, the controller 40 controls the running state of the floor brush 20 so that the floor brush 20 does not move, realizing that the cleaning device 1 does not move any more after stopping, which greatly facilitates the user to manage the cleaning device 1. ​

[0105] In one embodiment, when the body 10 is in an upright state, the rotational speed of the cleaning member 230 is less than or equal to the rotational speed of the cleaning member 230 when the cleaning device 1 performs a cleaning operation before shutdown. Herein, the rotational speed of the cleaning member 230 when the cleaning device 1 performs a cleaning operation before shutdown refers to the rotational speed of the cleaning member 230 when cleaning the surface to be cleaned before receiving a shutdown instruction.

[0106] By the above measures, on the basis of ensuring that the floor brush 20 does not displace, the rotational speed of the cleaning member 230 is adjusted so that when the body 10 is in an upright state after shutdown, the rotational speed of the cleaning member 230 is less than the rotational speed of the cleaning member 230 when performing a cleaning operation before shutdown, which is convenient for control.

[0107] ② If the controller 40 monitors that the body 10 is in a non-upright state, it can control the operating state of the floor brush 20 to change the body 10 from the non-upright state to the upright state.

[0108] In one embodiment, the controller 40 can control the operating state of the floor brush 20 in the following manner, and then change the body 10 from the non-upright state to the upright state:

[0109] Control the floor brush 20 to move backward, and then change the body 10 from the non-upright state to the upright state by controlling the movement of the floor brush 20. After that, when the controller 40 monitors that the body 10 is in an upright state, it can still control the operating state of the floor brush 20 to prevent the floor brush 20 from displacing. Herein, when controlling the floor brush 20 to move backward, the floor brush 20 is subjected to a first traction force F moving backward.

[0110] In this embodiment, a first traction force F is applied to the floor brush 20, and the first traction force F causes the floor brush 20 to move in the direction as shown by the arrow. As the floor brush 20 moves, the body 10 gradually returns to the upright state. When the floor brush 20 moves to the target position as shown by Figure 6 the arrow, the body 10 returns to the upright state. After that, when it is monitored that the body 10 has returned to the upright state, the controller 40 can control the operating state of the floor brush 20 to prevent the floor brush 20 from displacing. Specifically, the principle of controlling the floor brush 20 not to displace is as described in the above embodiment and will not be elaborated herein. Figure 1 shown, the body 10 returns to the upright state. After that, when it is monitored that the body 10 has returned to the upright state, the controller 40 can control the operating state of the floor brush 20 to prevent the floor brush 20 from displacing. Specifically, the principle of controlling the floor brush 20 not to displace is as described in the above embodiment and will not be elaborated herein.

[0111] In one embodiment, the controller 40 can control the floor brush 20 to move backward in the following manner:

[0112] Method 1: Control the cleaning member 230 to rotate in a first direction; wherein, the first traction force is generated by the rotation of the cleaning member 230.

[0113] Exemplarily, as Figure 8 shown, in this embodiment, the controller 40 can control the cleaning member 230 to rotate as shown byFigure 8 If it rotates counterclockwise as indicated by the arrow, the first traction force F is generated by the rotation of the cleaning member 230 at this time. As Figure 8 shown, when the cleaning member 230 rotates to generate the traction force F 1 at this time, the first traction force F is Figure 8 the traction force F in 1 .

[0114] Method 2: Control the cleaning member 230 to rotate in the second direction, and control the assisting unit 210 to rotate in the third direction; wherein, the second direction is the same as the third direction.

[0115] Exemplarily, as Figure 9 shown, in this embodiment, the controller 40 can control the cleaning member 230 and the assisting unit 210 to rotate counterclockwise as indicated by the arrow in Figure 9 at the same time. During the rotation process, the cleaning member 230 rotates to generate the fourth traction force F 2 , and the assisting unit 210 rotates to generate the fifth traction force Fx. At this time, the first traction force F is composed of the fourth traction force F 2 and the fifth traction force F 3 superimposed, that is, at this time F = F 2 + F 3 .

[0116] Method 3: Control the cleaning member 230 to rotate in the second direction, and control the assisting unit 210 to rotate in the third direction; wherein, the second direction is opposite to the third direction.

[0117] Exemplarily, as Figure 10 shown, in this embodiment, the controller 40 can control the cleaning member 230 to rotate clockwise as indicated by the arrow in Figure 10 , and at the same time, control the assisting unit 210 to rotate counterclockwise as indicated by the arrow in Figure 10 . During the rotation process, the cleaning member 230 rotates to generate the fourth traction force F 2 , and the fifth traction force F 3 is generated during the rotation of the assisting unit 210. At this time, the first traction force F is composed of the fourth traction force F 2 and the fifth traction force F 3 superimposed, and the fifth traction force F 3 is greater than the fourth traction force F 2 , that is, at this time F = F 3 - F 2 . Further, the rotation speed of the assisting unit 210 is greater than the rotation speed of the cleaning member 230.

[0118] Exemplarily, as Figure 11 shown, in this embodiment, the controller 40 can control the cleaning member 230 to rotate as indicated by the arrow in Figure 11Rotate counterclockwise as indicated by the arrow. Meanwhile, control the boosting unit 210 to rotate clockwise as indicated by the arrow in Figure 11 Rotate clockwise as indicated by the arrow. During the rotation, the cleaning part 230 rotates to generate a fourth traction force F 2 , and the boosting unit 210 generates a fifth traction force F during the rotation 3 . At this time, the first traction force F is composed of the superposition of the fourth traction force F 2 and the fifth traction force F 3 , that is, at this time F = F 2 - F 3 .

[0119] It should be noted that in this embodiment, the cleaning part 230 can rotate in an alternating manner of clockwise and counterclockwise. Correspondingly, at this time, the boosting unit 210 also needs to rotate in an alternating manner of clockwise and counterclockwise.

[0120] In an embodiment, when it is monitored that the rotation duration of the cleaning part 230 reaches the first preset duration, the controller 40 can control the cleaning part 230 and the boosting unit 210 to stop rotating.

[0121] By the above measures, when the body 10 is in a non-erect state when receiving the shutdown instruction, control the floor brush 20 to move backward, and thus restore the body 10 from the non-erect state to the erect state in this way. Because after the cleaning device 1 shuts down, for the convenience of management, the user will restore the body 10 to the erect state by himself. In the above method, moving the floor brush 20 backward reduces the resistance when the body 10 becomes erect, helps the user, and enables the user to more conveniently restore the body 10 to the erect state. At the same time, in the above method, when the body 10 becomes erect, the controller 40 can still make the floor brush 20 not displace by controlling the operating state of the floor brush 20, so that the cleaning device 1 does not move after shutdown, which greatly facilitates the user to manage the cleaning device 1.

[0122] In the above Embodiment ②, the body 10 will experience a process of changing from non-erect to erect state; among them, when the body 10 is in the erect state, the controller 40 can control the sewage suction assembly 110 to operate at the first power; when the body 10 is in the non-erect state, the controller 40 can control the sewage suction assembly 110 to operate at the second power; the second power is less than the first power.

[0123] Through the above measures, when the fuselage 10 is in a non-vertical state, the sewage in the sewage bucket is closer to the sewage suction assembly 110. When the sewage suction assembly 110 operates at a relatively low power, it can effectively prevent the water in the sewage bucket from entering the sewage suction assembly 110, thus effectively protecting the sewage suction assembly 110. In addition, when the fuselage 10 is in a non-vertical state, the operating resistance of the sewage suction assembly 110 is small, and a relatively low power can be used to suck the sewage into the sewage bucket, achieving an energy-saving effect.

[0124] In the above Embodiment ②, the fuselage 10 will experience a process of changing from a non-vertical state to a vertical state. Among them, when the fuselage 10 is in a non-vertical state, the rotation speed of the cleaning member 230 is less than the rotation speed of the cleaning member 230 when the fuselage 10 is in a vertical state.

[0125] Through the above measures, on the basis of ensuring that the floor brush 20 does not shift, the rotation speed of the cleaning member 230 is adjusted, and the rotation speed of the cleaning member 230 in the vertical state is reduced, which is convenient for control.
