Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a cleaning device. BACKGROUND

[0002] With the improvement of people's living standards, cleaning devices have been widely used in people's lives. Specifically, the cleaning device usually includes a machine body and a floor brush assembly pivotally connected to the machine body, the floor brush assembly includes a cleaning piece and a dirt suction port, the cleaning piece is used for cleaning the surface to be cleaned, the machine body includes a fan, a dirt suction channel and a sewage tank communicated with the dirt suction channel, and the dirt suction port is communicated with the dirt suction channel. When the cleaning device works, the cleaning piece cleans the surface to be cleaned, and at the same time the fan cooperates with the cleaning piece to suck the sewage formed after cleaning into the sewage tank through the dirt suction port and the dirt suction channel. The above process is continued until the cleaning device completes the cleaning work.

[0003] In the prior art, when the cleaning device receives a shutdown instruction, the cleaning piece will immediately stop rotating, and then the fan will be closed after a certain delay. The purpose of delaying the closing of the fan is to enable the fan to suck the sewage in the dirt suction channel into the sewage tank, thereby avoiding the residual sewage in the dirt suction channel flowing to the surface to be cleaned under the action of gravity when the cleaning device stops working, and causing secondary pollution to the surface that has been cleaned.

[0004] However, in the above-mentioned manner, since the cleaning piece will immediately stop rotating when the shutdown instruction is received, the cleaning piece will be in close contact with the surface to be cleaned to form an almost airtight end face. In this case, there is no air flow in the dirt suction channel, which causes that even if the fan is turned to the maximum gear, the residual sewage in the dirt suction channel cannot be completely sucked into the sewage tank. Eventually, even if the fan is delayed to be closed after the cleaning device stops, the residual sewage in the dirt suction channel cannot be completely collected, and part of the sewage will still flow to the surface that has been cleaned under the action of gravity, causing secondary pollution. SUMMARY

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

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

[0017] It is judged whether the machine body is in an upright state;

[0018] If the machine body is not in the upright state, the running state of the floor brush is controlled to move the floor brush backward, so that the machine body changes from the non-upright state to the upright state; wherein the floor brush is subjected to the first traction force for moving backward.

[0019] If the machine body is in the upright state, the running state of the floor brush is controlled to make the floor brush not displace.

[0020] In an embodiment, the floor brush is further provided with a power assisting unit, and the running state of the floor brush is controlled to make the floor brush not displace, which comprises:

[0021] The cleaning member and the power assisting unit are controlled to rotate in opposite directions;

[0022] Wherein the cleaning member rotation generates a second traction force, the power assisting unit rotation generates a third traction force, the second traction force and the third traction force are equal in size and opposite in direction.

[0023] In an embodiment, the floor brush is further provided with a power assisting unit, and the running state of the floor brush is controlled to move the floor brush backward, which comprises:

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

[0025] Or,

[0026] The control device controls the cleaning member to rotate in a second direction and controls the power-assisted unit to rotate in a third direction; the second direction is the same as or opposite to the third direction, the cleaning member rotation generates a fourth traction force, the power-assisted unit rotation generates a fifth traction force, and the first traction force is formed by superposition of the fourth traction force and the fifth traction force.

[0027] In an embodiment, the control method of the cleaning device further comprises:

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

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

[0033] When the machine 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 cleaning operation before receiving the shutdown instruction.

[0034] The present application provides a control method of a cleaning device, which is applied to a cleaning device. The cleaning device comprises a machine body and a floor brush. The machine body and the floor brush are pivotally connected. The floor brush is provided with a cleaning member.

[0035] It can be seen that, in the present application, when the shutdown instruction is received, the controller controls the cleaning piece and the sewage suction assembly to operate for a period of time. On the one hand, the cleaning piece is closed for a period of time, and the sewage suction assembly is used to suck the sewage, so that an air flow channel is formed between the sewage suction channel and the external environment, and the sewage remaining in the sewage suction channel is collected into the sewage tank. On the other hand, when the shutdown instruction is received, the cleaning piece may still have sewage thereon, and the cleaning piece is closed for a period of time, so that the cleaning piece rotates continuously, the sewage on the cleaning piece is stripped off, and the sewage is sucked into the sewage tank by the sewage suction assembly after being stripped off, the cleaning piece is cleaned, and secondary pollution caused by the sewage on the cleaning piece remaining on the ground is avoided. In addition, the cleaning piece closed for a period of time causes the sewage not sucked into the sewage tank by the sewage suction assembly to be adsorbed by the rotating cleaning piece in the process of flowing to the sewage suction opening under the action of gravity, so that the sewage does not fall to the ground and pollute the ground. The sewage suction assembly is closed for a period of time, and the sewage remaining in the sewage suction channel is sucked in cooperation with the rotation of the cleaning piece, so that the sewage is prevented from overflowing and polluting the ground. Therefore, the present application effectively prevents the residual sewage in the sewage suction channel from flowing to the surface to be cleaned after the cleaning equipment is shut down, and fully improves the use experience of the user.

DETAILED DESCRIPTION

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

[0051] Similar reference signs and letters represent similar items in the following drawings, thus, once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings. Meanwhile, in the description of the present application, the terms "first", "second", etc. are only used to distinguish description, and cannot be understood as indicating or implying relative importance.

[0052] Please refer to Figure 1 which is a structural schematic diagram of the cleaning device 1 provided by an embodiment of the present application. Please refer to Figure 2 which is a connection schematic diagram of the controller 40 provided by an embodiment of the present application. As shown in Figure 1As shown, the cleaning device 1 in this application includes a body 10 and a floor brush 20 pivotally connected to the body 10. The floor brush 20 is equipped with a cleaning component 230 and an assist unit 210. The cleaning component 230 is rotatably mounted on the floor brush 20 and is used to clean the surface to be cleaned. The assist unit 210 is rotatably mounted on the floor brush 20, reducing the friction between the floor brush 20 and the ground, making it easier for the user to clean the surface by hand. For example, the assist unit 210 can be a track or a support wheel. Further, the assist unit 210 can be a support wheel with a drive motor. According to the direction of movement of the floor brush 20, the drive motor drives the assist unit 210 to rotate to provide assistance to the floor brush 20 in the same direction of movement, thus saving the user effort and making operation convenient. The assist unit 210 can also be a support wheel with a diameter greater than or equal to the diameter of the cleaning component 230, providing support for the floor brush 20. The cleaning component 230 can be a tracked cleaning component 230 or a roller brush cleaning component 230; when the cleaning component 230 is a roller brush cleaning component 230, the floor brush 20 can have one or more roller brushes, forming a single-roller cleaning method or a multi-roller cleaning method depending on the number of roller brushes. The machine body 10 is equipped with a suction component 110 and a controller 40; the suction component 110 is used to absorb dirt from the surface to be cleaned; such as... Figure 2 As shown, the controller 40 is connected to the cleaning component 230, the assist unit 210, and the suction assembly 110. The controller 40 is used to identify the operating status of the cleaning equipment 1 and control the operating status of the cleaning component 230, the assist unit 210, and the suction assembly 110. An exemplary suction assembly 110 can be a blower.

[0053] like Figure 1 As shown, a handle assembly 120 is formed on the body 10, allowing the user to operate the cleaning device 1 by holding the handle assembly 120. The handle assembly 120 has a selection button 121 for operating the cleaning device 1. A trigger switch 30 is provided on the floor brush 20, which can be used to detect the posture of the body 10. The body 10 has a wastewater tank, and the floor brush 20 has a suction port near the cleaning component 230 on its bottom surface. The floor brush 20 has a suction channel 220 communicating with the suction port, and the suction channel 220 extends into the body 10 and communicates with the wastewater tank. Additionally, the body 10 has a clean water tank for supplying water to the cleaning component 230.

[0054] When the cleaning operation is performed, the main body 10 is in an inclined state, under the control of the controller 40, the suction assembly 110 and the cleaning element 230 are operated, and the controller 40 controls the clean water box to supply liquid to the cleaning element 230; the cleaning element 230 in a wet state will produce physical friction with the surface to be cleaned in the process of rotation, so as to remove the stains on the surface to be cleaned. Further, the suction assembly 110 is operated to generate a suction force, and the dirt adhered to the cleaning element 230 or the surface to be cleaned is sucked into the suction channel 220 through the sewage port under the action of the suction force of the suction assembly 110, and 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 structural schematic diagram of the controller 40 provided by an embodiment of the present application. As shown in Figure 3 , the controller 40 comprises at least one processor 43 and a memory 41, Figure 3 , taking a processor 43 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, and the instructions are executed by the processor 43 to enable the controller 40 to execute all or part of the processes of the method in the following embodiments.

[0056] The memory 41 can be realized 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, the storage medium stores a computer program, the computer program can be executed by the processor 43 to complete the control method of the cleaning equipment 1 provided by the following embodiments of the present application.

[0058] Please refer to Figure 4 , which is a flowchart of the control method of the cleaning equipment 1 provided by an embodiment of the present application. The method can be executed by Figure 3 the controller 40 shown in the figure, and the method comprises the following steps S210-S220.

[0059] Step S210: When the controller 40 receives a stop command during the cleaning operation of the cleaning device 1, the controller 40 controls the cleaning member 230 to run for a first preset time length.

[0060] In this step, the cleaning device 1 can perform the cleaning operation on the surface to be cleaned when receiving a cleaning command. Specifically, the body 10 can be provided with a selection button 121, and the user can trigger the selection button 121 to make the cleaning device 1 run in the corresponding mode to clean the surface to be cleaned. For example, the selection button 121 can be a hardware button, or the body 10 can be provided with a touch screen, and the selection button 121 can be a touch button provided on the touch screen.

[0061] During the cleaning operation of the cleaning device 1, the controller 40 can monitor whether a stop command is received in real time. Specifically, the user can trigger the selection button 121 to send a stop command to the controller 40. Alternatively, the state of the body 10 can be monitored, and when the body 10 is in an upright state as shown in Figure 1 , the controller 40 can be considered to have received a stop command. For example, the trigger switch 30 can monitor the state of the body 10 and feed back to the controller 40, and when the trigger switch 30 detects that the body 10 is in an upright state as shown in Figure 1 , the trigger switch 30 can send a monitoring signal to the controller 40, and when the controller 40 receives the monitoring signal, it is considered to have received a stop command.

[0062] It is worth noting that, as shown in Figure 5 , when the cleaning device 1 performs the 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 brush 20 to move by operating the handle assembly 120, so as to realize the cleaning of the surface to be cleaned by the brush 20. When the controller 40 detects that the body 10 changes from the upright state as shown in Figure 1 to the state as shown in Figure 5The non-erect state is automatically powered on. Alternatively, a selection button 121 is arranged on the handle assembly 120 of the machine body 10, and the selection button 121 comprises a power-on button, which can be a mechanical button or a touch screen button or any other form of trigger button. When the user presses the power-on button and the machine body 10 is in an erect state, the cleaning device 1 is powered on and can perform cleaning operations. After the cleaning device 1 is powered on, it moves under the user's control, the cleaning element 230 rotates and cleans the surface to be cleaned. Further, the power-assisted unit 210 can provide power assistance to the floor brush 20 in the same direction as the movement trend of the floor brush 20 during the cleaning process, so as to save the user's effort. The user can operate the cleaning device 1 at any time to stop the cleaning operation and power off the cleaning device 1 during the cleaning operation of the cleaning device 1. The user can power off the cleaning device 1 by restoring the machine body 10 from a non-erect state to an erect state or by operating the power-on button on the machine body 10. Therefore, when it is monitored that the machine body 10 is in an erect state or the power-on button is triggered, the controller 40 can consider that it has received a stop command.

[0063] Further, when the controller 40 monitors that it has received a stop command, the cleaning element 230 is controlled to continue to operate. After it is monitored that the operating time of the cleaning element 230 reaches a first preset time, the cleaning element 230 is controlled to stop operating. Exemplarily, the first preset time can be 20-60s.

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

[0065] In this step, after the controller 40 receives a stop command, it can control the suction assembly 110 to continue to operate. After it is monitored that the operating time of the suction assembly 110 reaches a second preset time, the suction assembly 110 is controlled to stop operating. Exemplarily, the second preset time can be 20-80s.

[0066] As can be seen, in the present application, when a stop command is received, the controller 40 controls the cleaning element 230 and the suction assembly 110 to operate for a period of time, so as to ensure that an air flow channel is formed between the atmosphere and the suction channel 220 during the operation of the cleaning element 230. After ensuring that the above-mentioned flow channel is formed, the suction resistance of the suction assembly 110 is reduced, so as to ensure that the suction assembly 110 can suck the residual sewage in the suction channel 220 into the sewage tank. This effectively avoids that the residual sewage in the suction channel 220 flows onto the surface to be cleaned after the cleaning device 1 is powered off, and fully improves the user's experience.

[0067] Further, when the stop command is received, there can be residual dirt on the part of the cleaning member 230 that is in contact with the surface to be cleaned. In the above embodiment, the cleaning member 230 is kept rotating by the delayed closing of the cleaning member 230, so that the residual dirt is cleaned, thereby improving the cleaning effect. For example, for the track-type cleaning member 230, the width is relatively long, and when the cleaning command is received, the cleaning member 230 can have residual dirt on the part that is in contact with the surface to be cleaned. In the above embodiment, the cleaning member 230 is kept rotating by the delayed closing of the cleaning member 230, so that the residual dirt is cleaned, thereby effectively solving the problem.

[0068] Further, when the stop command is received, there can be residual dirt on the part of the cleaning member 230 that is in contact with the surface to be cleaned. In the above embodiment, the cleaning member 230 is kept rotating by the delayed closing of the cleaning member 230, so that the residual dirt is cleaned, thereby improving the cleaning effect. For example, for the track-type cleaning member 230, the width is relatively long, and when the cleaning command is received, the cleaning member 230 can have residual dirt on the part that is in contact with the surface to be cleaned. In the above embodiment, the cleaning member 230 is kept rotating by the delayed closing of the cleaning member 230, so that the residual dirt is cleaned, thereby effectively solving the problem.

[0069] In an embodiment, when the stop command is received, the controller 40 can control the cleaning member 230 and the dirt suction assembly 110 to operate in a delayed manner by the following schemes:

[0070] Scheme 1: When the stop command is received, the controller 40 can simultaneously control the cleaning member 230 and the dirt suction assembly 110 to operate.

[0071] Scheme 2: When the stop command is received, the controller 40 can 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 period of time.

[0072] In this way, the cleaning member 230 is first kept operating in a delayed manner, and the floor brush can further be provided with a scraping strip that is in interference fit with the cleaning member 230. When the cleaning member 230 rotates, the dirt on the cleaning member 230 is stripped off from the cleaning member 230 by the scraping strip, and the residual dirt on the surface to be cleaned is removed by the rotation of the cleaning member 230. Then, after a period of time, the dirt suction assembly 110 is turned on to efficiently and centrally suck the dirt into the dirt tank, thereby further improving the cleaning effect. In addition, the residual dirt in the dirt suction channel 220 can be in the form of water droplets. The delayed turning on of the dirt suction assembly 110 can make the residual dirt in the form of water droplets converge, so that the dirt suction assembly 110 can better suck the dirt in the dirt suction channel 220, thereby further improving the dirt suction effect and effectively avoiding the residual dirt phenomenon.

[0073] Scheme 3: When the stop command is received, and after the cleaning member 230 and the dirt suction assembly 110 operate for a period of time, the cleaning member 230 and the dirt suction assembly 110 are simultaneously turned off.

[0074] Specifically, the combination of the first scheme and the third scheme can obtain a scheme that the cleaning member 230 and the sewage suction assembly 110 are simultaneously started and simultaneously stopped when the shutdown instruction is received, and the running time of the cleaning member 230, i.e., the first preset time, is equal to the total running time of the sewage suction assembly 110, i.e., the second preset time.

[0075] The combination of the second scheme and the third scheme can obtain a scheme that the controller 40 controls the cleaning member 230 to be started first, the sewage suction assembly 110 is started after a time interval, and then the cleaning member 230 and the sewage suction assembly 110 are simultaneously stopped after a time interval when the shutdown instruction is received, and the total running time of the cleaning member 230, i.e., the first preset time, is greater than the total running time of the sewage suction assembly 110, i.e., the second preset time.

[0076] The fourth scheme is that when the shutdown instruction is received and the running time of the cleaning member 230 reaches the first preset time, the cleaning member 230 is stopped. Then, the sewage suction assembly 110 is stopped after a time interval.

[0077] Through the above measures, the cleaning member 230 is stopped first, and then the sewage suction assembly 110 is stopped after a time interval, so that the sewage suction assembly 110 can suck as much residual sewage in the sewage suction channel 220 as possible into the sewage bucket, and the residual sewage in the sewage suction channel 220 is sufficiently avoided.

[0078] The combination of the fourth scheme and the first scheme can obtain a scheme that the cleaning member 230 and the sewage suction assembly 110 are simultaneously started when the shutdown instruction is received, and then the cleaning member 230 is stopped when the running time of the cleaning member 230 reaches the first preset time, and the sewage suction assembly 110 is stopped when the running time of the sewage suction assembly 110 reaches the second preset time, and the total running time of the cleaning member 230, i.e., the first preset time, is less than the total running time of the sewage suction assembly 110, i.e., the second preset time.

[0079] The combination of the fourth scheme and the second scheme can obtain a scheme that the controller 40 controls the cleaning member 230 to be started first, the sewage suction assembly 110 is started after a time interval, and then the cleaning member 230 is stopped after a time interval, and then the sewage suction assembly 110 is stopped after a time interval when the shutdown instruction is received. At this time, the total running time of the cleaning member 230, i.e., the first preset time, can be less than, greater than, or equal to the total running time of the sewage suction assembly 110, i.e., the second preset time.

[0080] The fifth scheme is that when the shutdown instruction is received and the running time of the sewage suction assembly 110 reaches the second preset time, the sewage suction assembly 110 is stopped, and then the cleaning member 230 is stopped after a time interval.

[0081] In order to facilitate the pivoting connection between the main body 10 and the brush 20, the suction passage 220 at the pivoting connection is usually designed as a special structure such as a threaded structure. Further, the suction passage 220 at the pivoting connection between the main body 10 and the brush 20 is a threaded hose. The threaded hose is provided with multiple folds therein, which is easy to store dirt. Due to insufficient power of the suction assembly 110 or the structure limitation of the suction passage 220, the sewage near the suction port in the suction passage 220 cannot be sucked into the sewage tank, and finally flows out to the ground along the suction port. Therefore, in order to solve the above problems, in the embodiment, the cleaning member 230 is closed in delay, so that the dirt in the suction passage 220 can be adsorbed by the rotating cleaning member 230 when the dirt is discharged from the suction port in the suction passage 220. Alternatively, when the dirt flows to the ground in the suction passage 220, the rotating cleaning member 230 can adsorb the dirt flowing to the ground, thereby avoiding the secondary pollution caused by the dirt remaining on the surface that has been cleaned.

[0082] The combination of scheme five and scheme one can obtain the scheme that when the shutdown instruction is received, the controller 40 simultaneously starts the cleaning member 230 and the suction assembly 110, and then monitors the running time of the suction assembly 110 to reach the second preset time, and then closes the suction assembly 110, and then delays for a period of time to close the cleaning member 230. 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 suction assembly 110, i.e. the second preset time.

[0083] The combination of scheme five and scheme two can obtain the scheme that when the shutdown instruction is received, the controller 40 controls the cleaning member 230 to be started first, and then the suction assembly 110 is started after a period of time, and then monitors the running time of the suction assembly 110 to reach the second preset time, and then closes the suction assembly 110, and then delays for a period of time to close the cleaning member 230. 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 suction assembly 110, i.e. the second preset time.

[0084] It can be seen that in the above embodiments, the cleaning member 230 and the suction assembly 110 are controlled to run in delay by different control modes, which have different cleaning effects, and the modes are flexible and variable, but are easy to control.

[0085] In an embodiment, when the controller 40 receives the shutdown instruction in the execution of the above step S210, the controller 40 also controls the power-assisted unit 210 to rotate.

[0086] In this embodiment, after receiving the shutdown instruction, the cleaning member 230 is delayed to shut down, and 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, the floor brush 20 is moved backward to clean the dirt possibly remaining on the ground, is convenient for the user to store, or is relatively stationary to be arranged on the ground without displacement, thereby reducing the force required by the user to hold the cleaning equipment. The power assisting unit 210 is arranged on the floor brush 20, the controller 40 controls the power assisting unit 210 and the cleaning member 230 to rotate at the same time, the power assisting unit 210 and the cleaning member 230 form rotation cooperation, and the running state of the floor brush 20 is controlled. Specifically, the principle of controlling the running state of the floor brush 20 is that the power assisting unit 210 and the cleaning member 230 exert corresponding traction forces on the floor brush 20 in the rotation process, and the running state of the floor brush 20 is controlled based on the size of the traction force.

[0087] The working principle of controlling the movement state of the floor brush 20 is explained in detail as follows:

[0088] (1) The cleaning member 230 and the power assisting unit 210 rotate at the same time, and the running state of the floor brush 20 is controlled to make the floor brush 20 not move.

[0089] In this embodiment, the cleaning member 230 and the power assisting unit 210 generate traction forces F 11 and F 12 in the rotation process, F 11 and F 12 are exerted on the floor brush 20, and the sizes of F 11 and F 12 are equal and the directions are opposite. The floor brush 20 does not move under the superimposed action of F 11 and F 12 .

[0090] Through the above measures, when the shutdown instruction is received, the running state of the cleaning member 230 and the power assisting unit 210 is controlled to make the floor brush 20 not move, the cleaning equipment 1 does not move after shutdown, and the user is greatly facilitated to manage the cleaning equipment 1.

[0091] (2) The cleaning member 230 and the power assisting unit 210 rotate at the same time, and the running state of the floor brush 20 is controlled to make the floor brush 20 move backward.

[0092] In this embodiment, the cleaning member 230 and the power assisting unit 210 generate traction forces F 21 and F 22 in the rotation process, and the traction forces F 21 and F 22 are exerted on the floor brush 20. Among them, the traction forces F 21 and F 22The superposition generates a first traction force F, the direction of the first traction force F is consistent with the direction of the arrow, and the brush 20 moves in the direction of the arrow under the action of the first traction force F. Figure 6 The superposition generates a first traction force F, the direction of the first traction force F is consistent with the direction of the arrow, and the brush 20 moves in the direction of the arrow under the action of the first traction force F. Figure 6 The superposition generates a first traction force F, the direction of the first traction force F is consistent with the direction of the arrow, and the brush 20 moves in the direction of the arrow under the action of the first traction force F.

[0093] For some cleaning devices 1, they do not have a straight-up shutdown function, that is, the cleaning device 1 does not shut down when the machine body 10 is restored to a straight-up state from a non-straight-up state. In this case, the user must trigger the on-off button on the handle to shut down the cleaning device 1. After that, because the machine body 10 is in an inclined state when the cleaning device 1 is performing a cleaning operation, the user needs to manually change the machine body 10 from a non-straight-up state to a straight-up state for easy storage. In the above embodiment, when the shutdown instruction is received, the running state of the brush 20 is controlled to move the brush 20 backward, which reduces the resistance of the machine body 10 when it becomes a straight-up state, provides assistance to the user, and enables the user to more easily restore the machine body 10 to a straight-up state.

[0094] In addition, the suction channel 220 at the pivot connection between the machine body 10 and the brush 20 is a threaded hose. The threaded hose is provided with multiple folds inside, which is easy to accumulate dirt. Due to insufficient power of the suction assembly 110 or structural limitations of the above-mentioned suction channel 220, the sewage near the suction port in the suction channel 220 cannot be sucked into the sewage tank, and eventually flows out onto the ground along the suction port. In the embodiment, the running state of the brush 20 is controlled to move the brush 20 backward, so that the cleaning member 230 can adsorb the dirt flowing onto the ground, effectively preventing the dirt from remaining on the surface that has been cleaned to cause secondary pollution.

[0095] In an embodiment, when the controller 40 receives the control instruction in the execution of the above-mentioned step S210, it will also perform the following steps:

[0096] determine whether the machine body 10 is in a straight-up state, and perform different operations based on the determination result.

[0097] In the embodiment, when the controller 40 receives the shutdown instruction, it will determine whether the machine body 10 is in a straight-up state as shown in FIG. 8. Specifically, the determination method can be that the trigger switch 30 detects the state of the machine body 10, and when it detects that the machine body 10 is in a straight-up state as shown in FIG. 8, the trigger switch 30 can send a monitoring signal to the controller 40, and when the controller 40 receives the monitoring signal, it can determine that the machine body 10 is in a straight-up state. Further, when the controller 40 does not receive the monitoring signal, it can determine that the machine body 10 is in a non-straight-up state. Further, the trigger switch 30 can be a mechanical structure provided on the brush 20, or a micro switch provided on the machine body 10. Figure 1 Figure 1 ​​

[0098] When the state of the machine body 10 is determined, the controller 40 can perform different operations according to the judgment result, and the specific operation principle is explained in detail as follows:

[0099] If the controller 40 monitors that the machine body 10 is in an upright state, the running state of the ground brush 20 can be controlled to make the ground brush 20 not displace.

[0100] In an embodiment, the controller 40 can control the running state of the ground brush 20 to make the ground brush 20 not displace in the following way:

[0101] The cleaning member 230 and the power-assisted unit 210 are controlled to rotate in two opposite directions; wherein the rotation of the cleaning member 230 generates a second traction force, and the rotation of the power-assisted unit 210 generates a third traction force, the second traction force and the third traction force are equal in size and opposite in direction. Specifically, when the cleaning member 230 rotates in a clockwise direction, the power-assisted unit 210 can rotate in a counterclockwise direction; or when the cleaning member 230 rotates in a counterclockwise direction, the power-assisted 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-assisted unit 210 also needs to rotate in a clockwise and counterclockwise alternating manner.

[0102] For example, as shown in Figure 7 When the controller 40 detects that the machine body 10 is in an upright state, the cleaning member 230 can be controlled to rotate in a clockwise direction as shown in Figure 7 , and at this time the cleaning member 230 generates a second traction force F5 as shown in Figure 7 ; at the same time, the controller 40 can control the power-assisted unit 210 to rotate in a counterclockwise direction as shown in Figure 7 , and at this time the power-assisted unit 210 generates a third traction force F4 as shown in Figure 7 , the second traction force F4 and the third traction force F5 are equal in size and opposite in direction, and are both applied to the ground brush 20, at this time the ground brush 20 does not displace under the superposition of the above two traction forces.

[0103] In an embodiment, when 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-assisted unit 210 to stop rotating.

[0104] Through the above measures, when the machine body 10 is in an upright state, the controller 40 controls the running state of the ground brush 20 to make the ground brush 20 not displace, so that the cleaning equipment 1 does not move after stopping, greatly facilitating the user to manage the cleaning equipment 1.

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

[0106] Through the above measures, on the basis of ensuring that the ground brush 20 does not displace, the rotating speed of the cleaning member 230 is adjusted, so that the rotating speed of the cleaning member 230 when the machine body 10 is in the upright state after shutdown is less than the rotating speed of the cleaning member 230 when the cleaning member 230 performs the cleaning operation before shutdown, which is convenient for control.

[0107] If the controller 40 monitors that the machine body 10 is in the non-upright state, the operating state of the ground brush 20 can be controlled to make the machine body 10 change from the non-upright state to the upright state.

[0108] In an embodiment, the controller 40 can control the operating state of the ground brush 20 to make the machine body 10 change from the non-upright state to the upright state in the following manner:

[0109] The ground brush 20 is controlled to move backward, and then the machine body 10 is made to change from the non-upright state to the upright state by controlling the movement of the ground brush 20. After that, when the controller 40 monitors that the machine body 10 is in the upright state, the ground brush 20 can still be controlled to not displace by controlling the operating state of the ground brush 20. Here, when the ground brush 20 is controlled to move backward, the ground brush 20 is subjected to the first traction force F moving backward.

[0110] In this embodiment, the first traction force F is applied to the ground brush 20, and the first traction force F makes the ground brush 20 move in the direction as shown by the arrow. Figure 6 With the movement of the ground brush 20, the machine body 10 gradually recovers to the upright state. When the ground brush 20 moves to the target position as shown by the arrow, Figure 1 the machine body 10 recovers to the upright state. After that, when it is monitored that the machine body 10 recovers to the upright state, the controller 40 can control the ground brush 20 to not displace by controlling the operating state of the ground brush 20. Specifically, the principle of controlling the ground brush 20 to not displace is described in the above embodiment, which will not be described here.

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

[0112] Manner one: the cleaning member 230 is controlled to rotate in the first direction; and the first traction force is generated by the rotation of the cleaning member 230.

[0113] For example, as shown in the figure, Figure 8 in this embodiment, the controller 40 can control the cleaning member 230 to rotate in the direction as shown by the arrow, Figure 8If the rotation is counterclockwise as indicated by the middle arrow, then the first traction force F is generated by the rotation of the cleaning component 230. For example... Figure 8 As shown, when the cleaning component 230 rotates and generates a traction force F1, the first traction force F is... Figure 8 The traction force F1 in the middle.

[0114] Method 2: Control the cleaning component 230 to rotate in the second direction and control the assist unit 210 to rotate in the third direction; wherein, the second direction and the third direction are the same.

[0115] For example, such as Figure 9 As shown, in this embodiment, the controller 40 can control the cleaning component 230 and the assist unit 210 to simultaneously perform the following actions: Figure 9 The rotation is counterclockwise as indicated by the middle arrow. During the rotation, the cleaning component 230 rotates to generate a fourth traction force F2, and the assist 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, F = F2 + F3.

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

[0117] For example, such as Figure 10 As shown, in this embodiment, the controller 40 can control the cleaning component 230 to perform the following actions: Figure 10 Rotate clockwise as indicated by the middle arrow, while simultaneously controlling the assist unit 210 to follow the... Figure 10 The rotation is counterclockwise as indicated by the middle arrow. During rotation, the cleaning component 230 generates a fourth traction force F2, and the assist unit 210 generates a fifth traction force F3. At this time, the first traction force F is 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, F = F3 - F2. Furthermore, the rotational speed of the assist unit 210 is greater than the rotational speed of the cleaning component 230.

[0118] For example, such as Figure 11 As shown, in this embodiment, the controller 40 can control the cleaning component 230 to perform the following actions: Figure 11 Rotate counterclockwise as indicated by the middle arrow, while simultaneously controlling the assist unit 210 to follow the... Figure 11 The rotation is clockwise as indicated by the middle arrow. During the rotation, the cleaning component 230 generates a fourth traction force F2, and the assist unit 210 generates a fifth traction force F3 during its rotation. 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, F = F2 - F3.

[0119] It is worth noting that in this embodiment, the cleaning member 230 can rotate in an alternating manner of clockwise and counterclockwise, and accordingly, the power assisting 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 time of the cleaning member 230 reaches the first preset time, the controller 40 can control the cleaning member 230 and the power assisting unit 210 to stop rotating.

[0121] Through the above measures, when the machine body 10 is in a non-upright state after receiving the stop command, the floor brush 20 moves backward, thereby restoring the machine body 10 from the non-upright state to the upright state. Since the cleaning equipment 1 is stopped, the user will restore the machine body 10 to the upright state for management. In the above manner, the floor brush 20 moves backward, which reduces the resistance of the machine body 10 when it becomes upright, provides assistance to the user, and makes it easier for the user to restore the machine body 10 to the upright state. At the same time, in the above manner, when the machine body 10 becomes upright, the controller 40 can still control the floor brush 20 to not displace by controlling the running state of the floor brush 20, so that the cleaning equipment 1 does not move after stopping, which greatly facilitates the user to manage the cleaning equipment 1.

[0122] In the above embodiment ②, the machine body 10 will undergo a process of changing from a non-upright state to an upright state; wherein, when the machine body 10 is in the upright state, the controller 40 can control the sewage suction assembly 110 to operate at a first power; when the machine body 10 is in the non-upright state, the controller 40 can control the sewage suction assembly 110 to operate at a second power; the second power is less than the first power.

[0123] Through the above measures, when the machine body 10 is in a non-upright state, the sewage in the sewage tank is closer to the sewage suction assembly 110, and when the sewage suction assembly 110 operates at a smaller power, it can effectively prevent the water in the sewage tank from entering the sewage suction assembly 110, thereby effectively protecting the sewage suction assembly 110. In addition, when the machine body 10 is in a non-upright state, the operating resistance of the sewage suction assembly 110 is smaller, and a smaller power can be used to suck the sewage into the sewage tank, thereby achieving the effect of energy saving.

[0124] In the above embodiment ②, the machine body 10 will undergo a process of changing from a non-upright state to an upright state; wherein, when the machine body 10 is in the non-upright state, the rotation speed of the cleaning member 230 is less than the rotation speed of the cleaning member 230 when the machine body 10 is in the upright state.

[0125] Through the above measures, on the basis of ensuring that the floor brush 20 does not displace, 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, thereby facilitating control.
