Description

Technical Field

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

[0002] With the improvement of people's living standards, cleaning equipment has been widely used in people's lives. Specifically, the cleaning equipment usually includes a body and a floor brush assembly pivotally connected to the body, the floor brush assembly includes a cleaning part and a sewage suction port, the cleaning part is used to clean the ground surface to be cleaned, the body includes a fan, a sewage suction channel and a sewage bucket connected to the sewage suction channel, and the sewage suction port is connected to the sewage suction channel. When the cleaning equipment is working, the cleaning part cleans the surface to be cleaned, and at the same time, the fan and the cleaning part cooperate to suck the sewage formed after cleaning into the sewage bucket through the sewage suction port and the sewage suction channel, and the above process continues until the cleaning equipment completes the cleaning work.

[0003] In the prior art, when the cleaning device receives a shutdown command, the cleaning part will stop rotating immediately, and then the fan will be turned off after a certain delay. The purpose of delaying the fan shutdown is to allow the fan to suck the sewage in the sewage suction channel into the sewage bucket, thereby avoiding the presence of sewage residue in the sewage suction channel when the cleaning device stops working. The residual sewage flows along the sewage suction channel to the ground under the action of gravity and finally flows out of the cleaning device to cause secondary pollution to the cleaned surface.

[0004] However, in the above method, since the cleaning part will stop rotating immediately upon receiving the shutdown command, the cleaning part will fit the surface to be cleaned to form a nearly closed end face. In this case, there is no air circulation in the sewage suction channel, which means that even if the fan is turned on to the maximum gear, it is impossible to suck all the sewage remaining in the sewage suction channel into the sewage bucket. Ultimately, even if the fan is turned off after the cleaning equipment is shut down, it cannot effectively collect all the sewage remaining in the sewage suction channel. Some sewage will still flow to the cleaned surface under the action of gravity, causing secondary pollution. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a control method for a cleaning device, which effectively avoids the problem of residual sewage in the sewage suction channel flowing onto the surface to be cleaned and causing secondary contamination after the cleaning device is shut down, thereby fully improving the user experience.

[0006] The present application provides a control method for a cleaning device, the cleaning device comprising a body and a floor brush pivotally connected to the body, a cleaning member disposed on the floor brush, a dirt suction component disposed in the body for absorbing dirt, and a controller for identifying the operating state of the cleaning device and controlling the cleaning member and the dirt suction component;

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

[0015] The running state of the floor brush is controlled so that the floor brush does not move.

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

[0017] Determine whether the fuselage is in an upright position;

[0018] If the body is in a non-upright state, controlling the running state of the floor brush to move the floor brush backward, thereby changing the body 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 machine body is in an upright state, the running state of the floor brush is controlled so that the floor brush does not move.

[0020] In one embodiment, a power-assisting unit is further provided on the floor brush to control the running state of the floor brush so that the floor brush does not move, including:

[0021] Controlling the cleaning element and the power-assisting unit to rotate in opposite directions;

[0022] The cleaning member rotates to generate a second traction force, and the power assist unit rotates to generate a third traction force. The second traction force is equal to the third traction force in magnitude but opposite in direction.

[0023] In one embodiment, a power-assisting unit is further provided on the floor brush to control the running state of the floor brush so that the floor brush moves backward, including:

[0024] Controlling the cleaning member to rotate in a first direction; wherein the first traction force is generated by the rotation of the cleaning member;

[0025] or,

[0026] The cleaning member is controlled to rotate in a second direction, and the power assist unit is controlled to rotate in a third direction; wherein the second direction is the same as or opposite to the third direction, the cleaning member rotates to generate a fourth traction force, the power assist unit rotates to generate 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 machine body is in an upright state, controlling the dirt suction component to operate at a first power;

[0029] If the body is in a non-upright state, the dirt suction assembly is controlled 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 time of the cleaning member reaches a first preset time, the cleaning member and the power-assisting unit are simultaneously controlled to stop rotating.

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

[0033] When the body 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 shutdown instruction.

[0034] The present application provides a control method for a cleaning device, which is applied to the cleaning device, wherein the cleaning device includes a body and a floor brush, wherein the body is pivotally connected to the floor brush, a cleaning member is provided on the floor brush, and a dirt suction component for absorbing dirt and a controller for controlling the cleaning member and the dirt suction component are provided in the body. The specific control method is that during the cleaning operation of the cleaning device, if the controller receives a stop command, the cleaning member is controlled to delay operation for a first preset time, and the dirt suction component is controlled to delay operation for a second preset time.

[0035] It can be seen from this that in this application, when a shutdown command is received, the controller will control the cleaning part and the dirt suction component to delay operation for a period of time. On the one hand, the cleaning part is closed with a delay, and the dirt suction component is assisted to suck the dirt, which promotes the formation of a circulated air flow channel between the dirt suction channel and the external environment, so that the dirt remaining in the dirt suction channel is collected in the sewage bucket. On the other hand, when the shutdown command is received, there may still be dirt on the cleaning part. By delaying the closing of the cleaning part, the cleaning part is continuously rotated to peel off the dirt on the cleaning part. At the same time, after peeling, the dirt is sucked into the sewage bucket by the dirt suction component to clean the cleaning part, and at the same time, the dirt on the cleaning part is prevented from being left on the ground to cause secondary pollution. Secondly, the cleaning part that is closed with a delay makes the dirt that is not sucked into the sewage bucket by the dirt suction component be adsorbed by the rotating cleaning part during the process of flowing toward the sewage suction port under the action of gravity, and will not fall on the ground and pollute the ground. The dirt suction component is closed with a delay, and the dirt remaining in the sewage suction channel is sucked in coordination with the rotation of the cleaning part to prevent the dirt from overflowing and polluting the ground. Therefore, the present application effectively prevents residual sewage in the sewage suction channel from flowing onto the surface to be cleaned after the cleaning device is shut down, thereby fully improving the user experience.

At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0052] Please refer to Figure 1 , which is a schematic diagram of the structure of a cleaning device 1 provided in an embodiment of the present application. Figure 2 , which is a connection diagram of the controller 40 provided in one embodiment of the present application. Figure 1As shown, the cleaning device 1 in the present application includes a body 10 and a floor brush 20 pivotally connected to the body 10. A cleaning member 230 and a power-assisting unit 210 are provided on the floor brush 20; the cleaning member 230 is rotatably arranged on the floor brush 20, and the cleaning member 230 is used to clean the surface to be cleaned on the ground; the power-assisting unit 210 is rotatably arranged on the floor brush 20, reducing the friction between the floor brush 20 and the ground, so that the user can save more effort when holding the cleaning device 1 to clean the surface to be cleaned. Exemplarily, the power-assisting unit 210 can be a track or a support wheel. Further, the power-assisting unit 210 can be a support wheel with a driving motor. According to the movement direction of the floor brush 20, the driving motor drives the power-assisting unit 210 to rotate to provide the floor brush 20 with the same power as its movement direction, so that the user saves effort and the operation is convenient. The power-assisting unit 210 can also be a supporting wheel, the diameter of which is greater than or equal to the diameter of the cleaning member 230, providing support force for the floor brush 20. The cleaning member 230 may be a crawler-type cleaning member 230 or a roller-brush-type cleaning member 230;

[0053] When the cleaning member 230 is a roller brush type cleaning member 230, the floor brush 20 may be provided with one roller brush or at most five roller brushes, and a single roller cleaning method or a multi-roller cleaning method may be formed according to the number of roller brushes.

[0054] The body 10 is provided with a dirt suction component 110 and a controller 40; the dirt suction component 110 is used to absorb dirt on the surface to be cleaned; Figure 2 As shown, the controller 40 is connected to the cleaning member 230, the booster unit 210 and the dirt suction assembly 110. The controller 40 is used to identify the operating state of the cleaning device 1 and to

[0055] The operating states of the component 230, the booster unit 210 and the sewage suction component 110 are controlled. The exemplary sewage suction component 110 may be a fan.

[0056] like Figure 1 As shown, a handle assembly 120 is formed on the body 10, and the user can control the cleaning device 1 by holding the handle assembly 120. A selection button 121 for controlling the cleaning device 1 is provided on the handle assembly 120. A trigger switch 30 is provided on the floor brush 20.

[0057] It can be used to detect the posture of the machine body 10. The machine body 10 is provided with a sewage bucket, and the bottom surface of the floor brush 20 is provided with a sewage suction port near the cleaning 5 piece 230, and the floor brush 20 is provided with a sewage suction channel 220 connected with the above-mentioned sewage suction port.

[0058] The sewage suction channel 220 extends into the body 10 and is communicated with the sewage bucket. In addition, a clean water box is provided on the body 10, and the clean water box is used to supply water to the cleaning member 230.

[0059] When performing the cleaning operation, the body 10 is in a tilted state. Under the control of the controller 40,

[0060] The dirt suction assembly 110 and the cleaning member 230 are in operation, and the controller 40 controls the clean water box to supply liquid to the cleaning member 230; the cleaning member 230 in a wet state will remove the stains on the surface to be cleaned by physical friction with the surface to be cleaned during the rotation process. Furthermore, the dirt suction assembly 110 is in operation, generating suction force, and the dirt adhering to the cleaning member 230 or the surface to be cleaned is drawn into the dirt suction channel 220 through the sewage outlet under the action of the suction force of the dirt suction assembly 110, and finally stored in the sewage bucket. The above process continues until the cleaning work of the surface to be cleaned is completed.

[0061] Please refer to Figure 3 , which is a schematic diagram of the structure of the controller 40 provided in one embodiment of the present application. Figure 3 As shown, the controller 40 includes: at least one processor 43 and a memory 41, Figure 3 A processor 43 is taken as an example. The processor 43 and the memory 41 are connected via a bus 42. The memory 41 stores instructions that can be executed by the processor 43. The instructions are executed by the processor 43 so that the controller 40 can execute all or part of the process of the method in the following embodiment.

[0062] 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 red-only memory (PROM), read-only memory (ROM), magnetic storage, flash memory, disk or optical disk.

[0063] The present application also provides a computer-readable storage medium, which stores a computer program. The computer program can be executed by the processor 43 to complete the control method of the cleaning device 1 provided in the following embodiment of the present application.

[0064] Please refer to Figure 4 , which is a flow chart of a control method of a cleaning device 1 provided in an embodiment of the present application. The method can be Figure 3The controller 40 shown in FIG. 1 is executed, and the method includes the following steps S210 to S220 .

[0065] Step S210: During the cleaning operation of the cleaning device 1, if the controller 40 receives a stop command, the cleaning element 230 is controlled to delay operation for a first preset time period.

[0066] In this step, when the cleaning device 1 receives the cleaning instruction, it can perform a cleaning operation on the surface to be cleaned. Specifically, a selection button 121 may be provided on the body 10, and the user can trigger the selection button 121 to make the cleaning device 1 operate in a corresponding mode to clean the surface to be cleaned. Exemplarily, the selection button 121 may be a hardware button, or the body 10 may be provided with a touch screen, and the selection button 121 may be a touch button provided on the touch screen.

[0067] During the cleaning operation of the cleaning device 1, the controller 40 monitors in real time whether a shutdown command is received. Specifically, the user can send a shutdown command to the controller 40 by triggering the selection button 121. Alternatively, the state of the body 10 can be monitored. When the state of the body 10 is detected as follows: Figure 1 40, the controller 40 considers that the shutdown command has been received. Figure 1 In the upright state shown, the trigger switch 30 can send a monitoring signal to the controller 40. When the controller 40 receives the monitoring signal, it is assumed that it has received a shutdown instruction.

[0068] It is worth noting that Figure 5 As shown, when the cleaning device 1 performs cleaning work, 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 that the floor brush 20 cleans the surface to be cleaned that it passes through. Figure 1 The upright position shown becomes Figure 5The cleaning device 1 is automatically turned on in the non-upright state shown. Alternatively, a selection button 121 is set on the handle assembly 120 of the body 10, and the selection button 121 includes a power button. The power button can be a mechanical button or a touch screen button or any other trigger button. When the user presses the power button and the body 10 is in the upright state, the cleaning device 1 is turned on and can perform cleaning operations. After the cleaning device 1 is turned on, it moves under the control of the user, and the cleaning member 230 rotates and cleans the surface to be cleaned. Further, during the cleaning process, the power unit 210 can provide the floor brush 20 with a power in the same direction as the movement trend of the floor brush 20 according to the movement direction of the floor brush 20, so that the user saves 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 shut down. The user can shut down the cleaning device 1 by restoring the body 10 from the non-upright state to the upright state or by operating the power button on the body 10. Therefore, when it is detected that the body 10 is in the upright state or the power button is triggered, the controller 40 can be considered that it has received a shutdown instruction.

[0069] Further, when the controller 40 detects that it has received a shutdown instruction, it controls the cleaning member 230 to continue to operate. After detecting that the operation time of the cleaning member 230 reaches a first preset time, the cleaning member 230 is controlled to stop operating. Exemplarily, the first preset time may be 20 to 60 seconds.

[0070] Step S220: controlling the sewage suction assembly 110 to delay operation for a second preset time period.

[0071] In this step, after receiving the shutdown instruction, the controller 40 can control the sewage suction assembly 110 to continue to operate. After monitoring that the operation time of the sewage suction assembly 110 reaches the second preset time, the sewage suction assembly 110 is controlled to stop operating. Exemplarily, the second preset time can be 20 to 80 seconds.

[0072] It can be seen from this that in this application, upon receiving a shutdown command, the controller 40 will control the cleaning member 230 and the dirt suction assembly 110 to delay operation for a period of time, thereby ensuring that an air circulation channel can be formed between the atmosphere and the dirt suction channel 220 during the operation of the cleaning member 230. After that, on the basis of ensuring the formation of the above-mentioned circulation channel, the dirt suction resistance of the dirt suction assembly 110 is reduced to ensure that the dirt suction assembly 110 can absorb the residual sewage in the dirt suction channel 220 into the sewage bucket. This effectively prevents the residual sewage in the dirt suction channel 220 from flowing onto the surface to be cleaned after the cleaning device 1 is shut down, fully improving the user experience.

[0073] Furthermore, when a shutdown command is received, there may still be stains remaining where the cleaning member 230 contacts the surface to be cleaned. In the above embodiment, the cleaning member 230 is turned off with a delay, so that the cleaning member 230 continues to rotate to clean the above residual stains, thereby fully improving the cleaning effect. For example, for a crawler-type cleaning member 230, its width is relatively long. When a cleaning command is received, there may still be stains remaining where the cleaning member 230 contacts the surface to be cleaned. In the above embodiment, the cleaning member 230 is turned off with a delay, which can effectively solve this problem.

[0074] Furthermore, when the shutdown command is received, there may still be dirt on the cleaning member 230. By delaying the shutdown of the cleaning member 230, the cleaning member 230 continues to rotate, and then the scraper provided on the floor brush 20 is used to peel off the dirt on the cleaning member 230. After peeling, the dirt is sucked into the sewage bucket by the dirt suction component 110. In this way, the dirt on the cleaning member 230 is cleaned and the cleanliness of the cleaning member 230 is improved.

[0075] In one embodiment, when receiving a stop command, the controller 40 can control the cleaning member 230 and the dirt suction assembly 110 to delay operation by the following scheme:

[0076] Solution 1: When receiving a shutdown command, the controller 40 can control the cleaning member 230 and the dirt suction assembly 110 to operate simultaneously.

[0077] Solution 2: When receiving a shutdown command, the controller 40 may first control the cleaning member 230 to operate, and then control the cleaning member 230 and the dirt suction assembly 110 to operate simultaneously after a certain period of time.

[0078] In this way, the cleaning member 230 is delayed in operation, and a scraper bar that is arranged in an interference fit with the cleaning member 230 can be provided on the floor brush. The cleaning member 230 rotates, and the scraper bar is used to peel off 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 residual stains on the surface to be cleaned. After a period of time, the dirt suction component 110 is turned on to efficiently absorb the above 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 drops. Delaying the opening of the sewage suction component 110 can make the residual sewage in the shape of water drops gather, so that the sewage suction component 110 can better suck out the sewage in the sewage suction channel 220, further improving the water absorption effect of the sewage in the sewage suction channel 220, and effectively avoiding the phenomenon of sewage residue.

[0079] Solution 3: When a shutdown command is received and it is detected that the cleaning member 230 and the dirt suction assembly 110 have been running for a period of time, the cleaning member 230 and the dirt suction assembly 110 are shut down simultaneously.

[0080] Specifically, a combination of Scheme 1 and Scheme 3 can result in a scheme in which, when a shutdown command is received, the cleaning component 230 and the dirt suction component 110 are turned on and off at the same time. At this time, the operating time of the cleaning component 230, i.e., the first preset time, and the total operating time of the dirt suction component 110, i.e., the second preset time, are equal.

[0081] Combining Scheme 2 with Scheme 3, it can be obtained that when a shutdown command is received, the controller 40 controls the cleaning component 230 to turn on first, and then turns on the dirt suction component 110 after a period of time, and then turns off the cleaning component 230 and the dirt suction component 110 at the same time after a period of time. At this time, the total operating time of the cleaning component 230, that is, the first preset time, is greater than the total operating time of the dirt suction component 110, that is, the second preset time.

[0082] Solution 4: When a shutdown command is received and it is detected that the operation time of the cleaning member 230 reaches the first preset time, the cleaning member 230 is turned off, and then the dirt suction assembly 110 is turned off after a delay.

[0083] Through the above measures, the cleaning member 230 is first closed, and then the sewage suction component 110 is closed with a delay, so that the sewage suction component 110 can suck the residual sewage in the sewage suction channel 220 into the sewage bucket as much as possible, and fully avoid the residual sewage in the sewage suction channel 220.

[0084] Combining Scheme 4 with Scheme 1, it can be obtained that when a shutdown command is received, the cleaning component 230 and the dirt suction component 110 are turned on at the same time, and then the cleaning component 230 is turned off when the running time of the cleaning component 230 reaches the first preset time, and the dirt suction component 110 is turned off when it is monitored that the running time of the dirt suction component 110 reaches the second preset time. At this time, the total running time of the cleaning component 230, i.e. the first preset time, is less than the total running time of the dirt suction component 110, i.e. the second preset time.

[0085] The fourth solution is combined with the second solution to obtain a solution 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 certain interval, and then first turns off the cleaning member 230 after a certain interval, and then delays the closing of the dirt suction assembly 110. At this time, the total operating time of the cleaning member 230, i.e., the first preset time, can be less than, greater than, or equal to the total operating time of the dirt suction assembly 110, i.e., the second preset time.

[0086] Solution 5: When a shutdown command is received and it is monitored that the operation time of the dirt suction component 110 reaches a second preset time, the dirt suction component 110 is turned off, and then the cleaning member 230 is turned off after a delay.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] In this embodiment, after receiving the shutdown command, the cleaning member 230 delays shutdown. 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 motion state of the floor brush 20, the floor brush 20 is moved 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 statically set on the ground without displacement to reduce the ground force required for the user to hold the cleaning device. A power-assisting unit 210 is set on the floor brush 20, and the controller 40 controls the power-assisting unit 210 and the cleaning member 230 to rotate at the same time, so that the power-assisting unit 210 and the cleaning member 230 form a rotational match, and control the running state of the floor brush 20. Specifically, the principle of controlling the running state of the floor brush 20 is: the power-assisting unit 210 and the cleaning member 230 will apply corresponding traction to the floor brush 20 during the rotation process, and the running state of the floor brush 20 is controlled based on the magnitude of the above traction force.

[0093] The working principle of controlling the motion state of the floor brush 20 is explained in detail below:

[0094] (1) The cleaning member 230 and the power-assisting unit 210 rotate simultaneously, and the running state of the floor brush 20 is controlled so that the floor brush 20 does not move.

[0095] In this embodiment, the cleaning member 230 and the power-assisting unit 210 generate a traction force F during the rotation process. 11 and F 12 , F 11 and F 12 are applied to the floor brush 20, and F 11 and F 12 The size of the brush 20 is equal and the direction is opposite. 11 and F 12 No displacement will occur under the superposition effect.

[0096] Through the above measures, when receiving the shutdown command, the cleaning member 230 and the power assist unit 210 are controlled.

[0097] The operating state makes the floor brush 20 not move, so that the cleaning device 1 no longer moves after being shut down, which greatly facilitates the user to manage the cleaning device 1.

[0098] (2) The cleaning member 230 and the power-assisting unit 210 rotate simultaneously, controlling the operating state of the floor brush 20 to move the floor brush 20 backward.

[0099] In this embodiment, the cleaning member 230 and the power-assisting unit 210 generate a traction force F during the rotation process. 21 and F 22 , traction force F 21 and F 22 are applied to the floor brush 20. Among them, the traction force F 21and F 22 0 superposition produces a first traction force F, the direction of the first traction force F is Figure 6 The direction indicated by the arrows is consistent.

[0100] Under the action of the first traction force F, the brush 20 moves to Figure 6 Move in the direction indicated by the arrow.

[0101] Some cleaning devices 1 do not have an upright shutdown function, that is, the cleaning device 1 does not shut down when the body 10 is restored from a non-upright state to an upright state. In this case, the user must

[0102] The cleaning device 1 can be turned off only by triggering the power button on the handle. Afterwards, since the cleaning device 1 is in a tilted state when performing the cleaning operation, the cleaning device 1 is placed in the tilted state for easy storage.

[0103] After shutting down, the user needs to manually change the body 10 from a non-upright state to an upright state. In the above embodiment, when receiving a shutdown command, the floor brush 20 is controlled to move backward by operating the floor brush 20, thereby reducing the resistance of the body 10 when it is turned to an upright state, thereby assisting the user and enabling the user to more conveniently restore the body 10 to an upright state.

[0104] In addition, the sewage suction channel 220 at the pivotal connection between the body 10 and the floor brush 20 is a threaded hose.

[0105] There are many wrinkles in the corrugated hose, which is easy to hide dirt. Due to insufficient power of the dirt suction component 110 or structural limitations of the dirt suction channel 220, the sewage near the dirt suction port in the dirt suction channel 220 cannot be sucked into the sewage bucket, and finally flows out to the ground through the dirt suction port. In this embodiment, by controlling the running state of the floor brush 20 to move backward, the cleaning member 230 can absorb the dirt flowing to the ground, effectively avoiding the dirt remaining on the cleaned surface to cause secondary pollution.

[0106] In one embodiment, when the controller 40 performs the above step S210 and receives the control instruction, it further performs the following steps:

[0107] It is determined whether the main body 10 is in the upright state, and different operations are performed based on the determination result.

[0108] In this embodiment, when the controller 40 receives the shutdown command, it determines whether the machine body 10 is in the following state: Figure 1 Specifically, the judgment method may be to trigger the switch 30 to detect the state of the body 10, and when it is detected that the body 10 is in the upright state as shown. Figure 1In the upright state shown, the trigger switch 30 can send a monitoring signal to the controller 40. When the controller 40 receives the monitoring signal, it can be determined that the body 10 is in the upright state. Further, when the controller 40 does not receive the monitoring signal, it can be determined that the body 10 is in the non-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.

[0109] After determining the state of the body 10, the controller 40 can perform different operations according to the determination result. The specific operation principle is explained in detail below:

[0110] ① If the controller 40 detects that the body 10 is in an upright state, the running state of the floor brush 20 can be controlled to prevent the floor brush 20 from being displaced.

[0111] 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:

[0112] The cleaning member 230 and the power-assisting unit 210 are controlled to rotate in two opposite directions; wherein the cleaning member 230 rotates to generate a second traction force, and the power-assisting unit 210 rotates to generate a third traction force, and the second traction force and the third traction force are equal in magnitude and opposite in direction. Specifically, when the cleaning member 230 rotates in a clockwise direction, the power-assisting unit 210 can rotate in a counterclockwise direction; or, when the cleaning member 230 rotates in a counterclockwise direction, the power-assisting unit 210 can rotate in a clockwise direction; or, the cleaning member 230 can rotate in a clockwise and counterclockwise alternating manner, and correspondingly, the power-assisting unit 210 also needs to rotate in a clockwise and counterclockwise alternating manner.

[0113] For example, Figure 7 As shown, when the controller 40 detects that the body 10 is in an upright state, the cleaning member 230 can be controlled to move in accordance with Figure 7 The cleaning member 230 rotates clockwise as shown in FIG. Figure 7 At the same time, the controller 40 can control the power unit 210 to follow the second traction force F5 shown in FIG. Figure 7 , the power assist unit 210 generates the following counterclockwise rotation: Figure 7 The third traction force F4, the second traction force F4 and the third traction force F5 shown are equal in magnitude and opposite in direction and are all applied to the floor brush 20. At this time, the floor brush 20 does not move under the superposition of the above two traction forces.

[0114] In one embodiment, when it is monitored that the rotation time of the cleaning member 230 reaches a first preset time, the controller 40 can control the cleaning member 230 and the power-assisting unit 210 to stop rotating.

[0115] Through the above measures, when it is monitored that the body 10 is in an upright state, the controller 40 controls the operating state of the floor brush 20 to prevent the floor brush 20 from moving, so that the cleaning device 1 no longer moves after shutdown, which greatly facilitates the user to manage the cleaning device 1.

[0116] In one embodiment, when the body 10 is in an upright state, the rotation speed of the cleaning member 230 is less than or equal to the rotation speed of the cleaning member 230 when the cleaning device 1 performs a cleaning operation before shutdown. The rotation speed of the cleaning member 230 when the cleaning device 1 performs a cleaning operation before shutdown refers to the rotation speed of the cleaning member 230 when cleaning the surface to be cleaned before receiving the shutdown command.

[0117] Through the above measures, on the basis of ensuring that the floor brush 20 does not move, the rotation speed of the cleaning member 230 is adjusted so that when the body 10 is in an upright state after shutdown, the rotation speed of the cleaning member 230 is less than the rotation speed of the cleaning member 230 when performing the cleaning operation before shutdown, which is easy to control.

[0118] ② If the controller 40 detects that the body 10 is in a non-upright state, the operating state of the floor brush 20 can be controlled to change the body 10 from the non-upright state to the upright state.

[0119] In one embodiment, the controller 40 can control the running state of the floor brush 20 in the following manner, thereby changing the body 10 from the non-upright state to the upright state:

[0120] The floor brush 20 is controlled to move backward, and the body 10 is changed from a non-upright state to an upright state by controlling the movement of the floor brush 20. Afterwards, when the controller 40 detects that the body 10 is in an upright state, the floor brush 20 can still be controlled to prevent displacement by controlling the running state of the floor brush 20. When the floor brush 20 is controlled to move backward, the floor brush 20 is subjected to a first traction force F moving backward.

[0121] 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 toward Figure 6 The body 10 gradually returns to the upright state as the floor brush 20 moves. Figure 1 When the body 10 is at the target position shown, the body 10 returns to the upright state. Afterwards, when the body 10 is detected to be restored to the upright state, the controller 40 can control the running state of the floor brush 20 so that the floor brush 20 does not move. Specifically, the principle of controlling the floor brush 20 not to move is detailed in the above embodiment and will not be repeated here.

[0122] In one embodiment, the controller 40 may control the floor brush 20 to move backward in the following manner:

[0123] 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 .

[0124] For example, Figure 8 As shown, in this embodiment, the controller 40 can control the cleaning member 230 to follow the following steps: Figure 8 The cleaning member 230 rotates counterclockwise as indicated by the middle arrow. At this time, the first traction force F is generated by the rotation of the cleaning member 230. Figure 8 As shown, when the cleaning member 230 rotates to generate a traction force F1, the first traction force F is Figure 8 The traction in F1.

[0125] Method 2: Control the cleaning member 230 to rotate in the second direction, and control the power-assisting unit 210 to rotate in the third direction; wherein the second direction is the same as the third direction.

[0126] For example, Fig. 9 As shown, in this embodiment, the controller 40 can control the cleaning member 230 and the power unit 210 to simultaneously follow the following steps: Fig. 9 During the rotation, the cleaning member 230 rotates to generate a fourth traction force F2, and the power unit 210 rotates to generate a fifth traction force F3. At this time, the first traction force F is formed by the superposition of the fourth traction force F2 and the fifth traction force F3, that is, at this time F=F2+F3.

[0127] Method three: controlling the cleaning member 230 to rotate in the second direction, and controlling the power-assisting unit 210 to rotate in the third direction; wherein the second direction is opposite to the third direction.

[0128] For example, Fig.10 As shown, in this embodiment, the controller 40 can control the cleaning member 230 to follow the following steps: Fig.10 The power assist unit 210 rotates in the clockwise direction as shown by the arrow in the middle. Fig.10 The cleaning member 230 rotates counterclockwise as indicated by the middle arrow. During the rotation process, the cleaning member 230 rotates to generate the fourth traction force F2, and the power unit 210 rotates to generate the fifth traction force F3. At this time, the first traction force F is formed by the superposition of the fourth traction force F2 and the fifth traction force F3, and the fifth traction force F3 is greater than the fourth traction force F2, that is, at this time F = F3-F2. Further, the rotation speed of the power unit 210 is greater than the rotation speed of the cleaning member 230.

[0129] For example, Fig.11 As shown, in this embodiment, the controller 40 can control the cleaning member 230 to follow the following steps: Fig.11 The power assist unit 210 rotates in the counterclockwise direction as shown by the arrow in the middle. Fig.11During the rotation, the cleaning member 230 generates a fourth traction force F2, and the power assist unit 210 generates a fifth traction force F3. At this time, the first traction force F is formed by the superposition of the fourth traction force F2 and the fifth traction force F3, that is, at this time, F=F2-F3.

[0130] It should be noted that, in this embodiment, the cleaning member 230 can rotate in a clockwise and counterclockwise manner, and accordingly, the power assist unit 210 also needs to rotate in a clockwise and counterclockwise manner.

[0131] In one embodiment, when it is monitored that the rotation time of the cleaning member 230 reaches a first preset time, the controller 40 can control the cleaning member 230 and the power-assisting unit 210 to stop rotating.

[0132] Through the above measures, if the machine body 10 is in a non-upright state when receiving the shutdown command, the floor brush 20 is controlled to move backward, and the machine body 10 is restored from the non-upright state to the upright state in this way.

[0133] In the above method, the floor brush 20 is moved backwards, which reduces the resistance of the body 10 when it is in the upright state, and helps the user to restore the body 10 to the upright state more conveniently.

[0134] At the same time, in the above manner, when the body 10 becomes in the upright state, the controller 40 can still prevent the floor brush 20 from being displaced by controlling the running state of the floor brush 20, so that the cleaning device 1 does not move after being stopped, which greatly facilitates the user to manage the cleaning device 1.

[0135] In the above embodiment ②, the body 10 undergoes a process of changing from a non-upright state to an upright state; in the embodiment 5, when the body 10 is in the upright state, the controller 40 can control the dirt suction assembly 110 to first

[0136] when the body 10 is in a non-upright state, the controller 40 may control the dirt suction assembly 110 to operate at a second power; the second power is less than the first power.

[0137] Through the above measures, when the body 10 is in a non-upright state, the sewage in the sewage bucket is away from the sewage suction device.

[0138] The distance between the sewage suction component 110 and the sewage suction component 110 is closer. When the sewage suction component 110 is operated with a smaller power, the water in the sewage bucket can be effectively prevented from entering the sewage suction component 110, thereby effectively protecting the sewage suction component 110.

[0139] In addition, when the body 10 is in a non-upright state, the running resistance of the sewage suction component 110 is relatively small, and the sewage can be sucked into the sewage bucket with relatively small power, thus achieving an energy-saving effect.

[0140] In the above embodiment ②, the body 10 undergoes a process of changing from a non-upright state to an upright state; wherein, when the body 10 is in the non-upright state, the rotation speed of the cleaning member 230 is lower than the rotation speed of the cleaning member 230 when the body 10 is in the upright state.

[0141] Through the above measures, on the basis of ensuring that the floor brush 20 does not move, the rotation speed of the cleaning member 230 is adjusted, and the rotation speed of the cleaning member 230 in the upright state is reduced, so as to facilitate control.
