Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a control method for a cleaning device. Background Technology

[0002] With the improvement of people's living standards, cleaning equipment has been widely used in people's lives. Specifically, cleaning equipment typically includes a main body and a floor brush assembly pivotally connected to the main body. The floor brush assembly includes a cleaning component and a suction port. The cleaning component is used to clean the surface to be cleaned. The main body includes a fan, a suction channel, and a wastewater tank connected to the suction channel. The suction port is connected to the suction channel. When the cleaning equipment is working, the cleaning component cleans the surface to be cleaned, while the fan, in conjunction with the cleaning component, sucks the wastewater generated after cleaning into the wastewater tank through the suction port and suction channel. This process continues until the cleaning equipment has completed the cleaning work.

[0003] In existing technology, when the cleaning equipment receives a shutdown command, the cleaning components immediately stop rotating, and then the fan is turned off after a certain delay. The purpose of delaying the fan shutdown is to allow the fan to suck the wastewater in the suction channel into the wastewater tank, thereby preventing wastewater residue from remaining in the suction channel when the cleaning equipment stops working. Residual wastewater would flow along the suction channel to the ground under gravity and eventually flow out of the cleaning equipment, causing secondary pollution to the cleaned surface.

[0004] However, in the above method, the cleaning component immediately stops rotating upon receiving the shutdown command. This causes the cleaning component to adhere to the surface to be cleaned, forming a near-sealed end face. In this situation, there is no airflow within the suction channel, meaning that even with the fan at its maximum setting, not all the residual wastewater in the suction channel can be sucked into the wastewater tank. Ultimately, even if the fan shuts down after a delay after the cleaning equipment stops, it cannot effectively collect all the residual wastewater in the suction channel. Some wastewater will still flow onto the already cleaned surface under gravity, causing secondary pollution. Summary of the Invention

[0005] The purpose of this application is to provide a control method for cleaning equipment, which effectively avoids the problem of residual sewage in the suction channel flowing onto the surface to be cleaned after the cleaning equipment is turned off, thus greatly improving the user experience.

[0006] This application provides a control method for a cleaning device, which includes a body and a floor brush pivotally connected to the body, a cleaning component disposed on the floor brush, a suction component disposed inside the body for adsorbing dirt, and a controller for identifying the operating status of the cleaning device and controlling the cleaning component and the suction component.

[0007] Control methods for cleaning equipment include:

[0008] If the controller receives a stop command during the cleaning operation, the cleaning components will be delayed for a first preset time.

[0009] The second preset duration for delaying the operation of the suction component is controlled.

[0010] In one embodiment, the floor brush is further provided with an assist unit. After the controller receives a stop command, the control method of the cleaning equipment includes:

[0011] Control the rotation of the assist unit.

[0012] In one embodiment, after the controller receives a shutdown command, the control method for the cleaning equipment includes:

[0013] The operation of the floor brush is controlled to move the floor brush backward; wherein the floor brush is subjected to a first traction force that moves backward.

[0014] In one embodiment, after the controller receives a shutdown command, the control method for the cleaning equipment includes:

[0015] The operating state of the floor brush is controlled to prevent the floor brush from shifting.

[0016] In one embodiment, after the controller receives a shutdown command, the control method for the cleaning equipment further includes:

[0017] Determine if the aircraft is in an upright position;

[0018] If the machine body is not in an upright position, the operation of the floor brush is controlled to move the floor brush backward, thereby changing the machine body from an upright position to an upright position; wherein, the floor brush is subjected to a first traction force that moves backward.

[0019] If the machine body is in an upright position, control the operation of the floor brush to prevent the floor brush from shifting.

[0020] In one embodiment, the floor brush is further provided with an assist unit to control the operating state of the floor brush so that the floor brush does not shift, including:

[0021] Control the cleaning component and the assist unit to rotate in opposite directions;

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

[0023] In one embodiment, the floor brush is further provided with an assist unit to control the operating state of the floor brush so that the floor brush moves backward, including:

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

[0025] or,

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

[0027] In one embodiment, the control method for the cleaning equipment further includes:

[0028] If the machine is in an upright position, control the suction component to operate at the highest power.

[0029] If the machine body is not in an upright position, the suction component 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 for the cleaning equipment further includes:

[0031] If the cleaning component rotates for a period of time that reaches the first preset duration, both the cleaning component and the assist unit will stop rotating.

[0032] In one embodiment, the control method for the cleaning equipment further includes:

[0033] When the machine body is in an upright position, the rotational speed of the cleaning components is less than or equal to the rotational speed of the cleaning components when the cleaning equipment performs the cleaning operation before receiving the stop command.

[0034] This application provides a control method for a cleaning device. The cleaning device includes a body and a floor brush, with the body pivotally connected to the floor brush. The floor brush has cleaning components, and the body contains a suction component for adsorbing dirt, as well as a controller for controlling the cleaning components and the suction component. Specifically, during the cleaning operation, if the controller receives a stop command, it controls the cleaning components to operate for a first preset time, and controls the suction component to operate for a second preset time.

[0035] Therefore, in this application, upon receiving a shutdown command, the controller will delay the operation of the cleaning component and the suction assembly for a period of time. On one hand, the delayed shutdown of the cleaning component assists the suction assembly in drawing out waste, promoting the formation of a flowable air channel between the suction channel and the external environment, allowing waste remaining in the suction channel to be collected into the wastewater tank. On the other hand, when the shutdown command is received, there may still be waste remaining on the cleaning component. By delaying the shutdown of the cleaning component, it continues to rotate, peeling off the waste. Simultaneously, the suction assembly draws the waste into the wastewater tank after peeling, cleaning the cleaning component and preventing waste from remaining on the ground and causing secondary pollution. Furthermore, the delayed shutdown of the cleaning component ensures that waste not drawn into the wastewater tank by the suction assembly is absorbed by the rotating cleaning component as it flows towards the suction port under gravity, preventing it from falling to the ground and polluting it. The delayed shutdown of the suction assembly, in conjunction with the rotation of the cleaning component, draws out the waste remaining in the suction channel, preventing waste from overflowing and polluting the ground. Therefore, this application effectively prevents residual sewage in the suction channel from flowing onto the surface to be cleaned after the cleaning equipment is turned off, thus greatly improving the user experience.

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

[0051] Similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0052] Please refer to Figure 1 This is a schematic diagram of the structure of a cleaning device 1 provided in an embodiment of this application. Please refer to... Figure 2 This is a connection diagram of the controller 40 provided in one embodiment of this application. 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] During the cleaning operation, the machine body 10 is tilted. Under the control of the controller 40, the suction assembly 110 and the cleaning component 230 operate. The controller 40 controls the water tank to supply liquid to the cleaning component 230. The wet cleaning component 230, during rotation, removes dirt from the surface to be cleaned through physical friction. Furthermore, the suction assembly 110 operates, generating suction force. Dirt adhering to the cleaning component 230 or the surface to be cleaned is drawn into the suction channel 220 through the wastewater outlet under the suction force of the suction assembly 110 and ultimately stored in the wastewater tank. This process continues until the cleaning of the surface is complete.

[0055] Please refer to Figure 3 This is a schematic diagram of the controller 40 provided in one embodiment of this application. Figure 3 As shown, the controller 40 includes: 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 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 to enable the controller 40 to perform all or part of the process of the method in the following embodiments.

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

[0057] This application also provides a computer-readable storage medium storing a computer program that can be executed by a processor 43 to perform the control method of the cleaning device 1 provided in the following embodiments of this application.

[0058] Please refer to Figure 4 This is a flowchart illustrating the control method of a cleaning device 1 provided in an embodiment of this application. The method can be... Figure 3 The controller 40 shown executes the method, which includes the following steps S210-S220.

[0059] Step S210: During the cleaning operation of the cleaning equipment 1, if the controller 40 receives a stop command, it controls the cleaning component 230 to run for a first preset time.

[0060] In this step, when the cleaning device 1 receives a cleaning command, it can perform a cleaning operation on the surface to be cleaned. Specifically, the device body 10 may be equipped with a selection button 121, which the user can trigger to operate the cleaning device 1 in the corresponding mode and clean the surface to be cleaned. For example, the selection button 121 may be a hardware button, or the device body 10 may be equipped with a touch screen, and the selection button 121 may be a touch button set on the touch screen.

[0061] During the cleaning operation of the cleaning equipment 1, the controller 40 monitors in real time whether a stop command has been received. Specifically, the user can send a stop command to the controller 40 by triggering the selection button 121. Alternatively, the controller can monitor the status of the machine body 10, and when the status of the machine body 10 is detected as follows... Figure 1 When the machine is in the upright position shown, the controller 40 considers it to have received a stop command. For example, the trigger switch 30 can monitor the state of the machine body 10 and feed it back to the controller 40. When it detects that the machine body 10 is in the upright position... Figure 1 When the device is in the upright position as shown, the trigger switch 30 can send a monitoring signal to the controller 40. When the controller 40 receives this monitoring signal, it assumes that it has received a stop command.

[0062] It is worth noting that, such as 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 by manipulating the handle assembly 120, thereby enabling the floor brush 20 to clean the surface to be cleaned. When the controller 40 detects that the body 10 is moved by the floor brush 20, the user can proceed to clean the surface to be cleaned. Figure 1 The upright state shown changes to as follows Figure 5The device automatically powers on when not in an upright position. Alternatively, a selection button 121 can be provided on the handle assembly 120 of the body 10. The selection button 121 includes a power button, which can be a mechanical button, a touch screen button, or any other trigger button. When the user presses the power button and the body 10 is in an upright position, the cleaning device 1 powers on and can perform cleaning operations. After the cleaning device 1 is powered on, it moves under the user's control, and the cleaning component 230 rotates to clean the surface to be cleaned. Furthermore, during the cleaning process, the assist unit 210 can provide assistance to the floor brush 20 in the same direction as the direction of the floor brush 20's movement, making it easier for the user. During the cleaning operation, the user can operate the cleaning device 1 at any time to stop the cleaning operation and turn it off. The user can turn off the cleaning device 1 by restoring the body 10 from an upright position to an upright position or by operating the power button on the body 10. Therefore, when the controller 40 detects that the body 10 is in an upright position or that the power button has been triggered, it can assume that it has received a stop command.

[0063] Furthermore, when the controller 40 detects that it has received a stop command, it controls the cleaning component 230 to continue operating. After detecting that the operating time of the cleaning component 230 has reached a first preset time, it controls the cleaning component 230 to stop operating. For example, the first preset time can be 20 to 60 seconds.

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

[0065] In this step, after receiving a stop command, the controller 40 can control the suction assembly 110 to continue operating. Then, after detecting that the operating time of the suction assembly 110 has reached a second preset duration, it controls the suction assembly 110 to stop operating. For example, the second preset duration can be 20–80 seconds.

[0066] Therefore, in this application, upon receiving a shutdown command, the controller 40 will delay the operation of the cleaning component 230 and the suction assembly 110 for a period of time. This ensures that an airflow channel can be formed between the atmosphere and the suction channel 220 during the operation of the cleaning component 230. After ensuring the formation of this airflow channel, the suction resistance of the suction assembly 110 is reduced, ensuring that the suction assembly 110 can absorb the residual wastewater in the suction channel 220 into the wastewater tank. This effectively prevents residual wastewater in the suction channel 220 from flowing onto the surface to be cleaned after the cleaning equipment 1 is shut down, significantly improving the user experience.

[0067] Furthermore, when a stop command is received, there may still be stains remaining where the cleaning component 230 contacts the surface to be cleaned. In the above embodiment, by delaying the shutdown of the cleaning component 230, the cleaning component 230 continues to rotate to clean away the remaining stains, thus significantly improving the cleaning effect. For example, for the tracked cleaning component 230, its width is relatively long, and when a cleaning command is received, there is a tendency for stains to remain where the cleaning component 230 contacts the surface to be cleaned. The above embodiment effectively solves this problem by delaying the shutdown of the cleaning component 230.

[0068] Furthermore, when a stop command is received, there may still be dirt remaining on the cleaning component 230. By delaying the shutdown of the cleaning component 230, it continues to rotate, allowing the scraper on the floor brush 20 to peel off the dirt. Simultaneously, the suction assembly 110 sucks the dirt into the wastewater tank. In this way, the dirt on the cleaning component 230 is cleaned, improving its cleanliness.

[0069] In one embodiment, when a stop command is received, the controller 40 can control the cleaning component 230 and the suction assembly 110 to operate for a delayed period of time through the following scheme:

[0070] Option 1: When a stop command is received, the controller 40 can simultaneously control the operation of the cleaning component 230 and the suction component 110.

[0071] Option 2: When a shutdown command is received, the controller 40 can first control the cleaning component 230 to operate, and then control the cleaning component 230 and the vacuuming component 110 to operate simultaneously after a period of time.

[0072] In this way, the cleaning component 230 operates with a delayed start. The floor brush can also be equipped with scrapers that are interference-fitted with the cleaning component 230. As the cleaning component 230 rotates, the scrapers peel away dirt from it. Simultaneously, the rotation of the cleaning component 230 removes residual stains from the surface to be cleaned. After a period of time, the suction assembly 110 is activated to efficiently collect the aforementioned dirt into the wastewater tank, further ensuring the cleaning effect. Furthermore, residual wastewater in the suction channel 220 may be in the form of droplets. Delaying the activation of the suction assembly 110 allows these droplets to collect, enabling the suction assembly 110 to better remove the wastewater from the suction channel 220, further improving the water absorption effect and effectively preventing wastewater residue.

[0073] Option 3: When a shutdown command is received and the cleaning component 230 and the vacuuming component 110 have been running for a period of time, the cleaning component 230 and the vacuuming component 110 shall be shut down simultaneously.

[0074] Specifically, combining Scheme 1 and Scheme 3 yields a scheme that simultaneously turns on and off the cleaning component 230 and the suction component 110 when a shutdown command is received. At this time, the running time of the cleaning component 230, i.e. the first preset time, and the total running time of the suction component 110, i.e. the second preset time, are equal.

[0075] Combining Scheme 2 and Scheme 3, we can obtain a scheme in which, when a shutdown command is received, the controller 40 controls the cleaning component 230 to turn on first, and after a certain period of time, the suction component 110 is turned on. After a certain period of time, the cleaning component 230 and the suction component 110 are turned off simultaneously. At this time, the total running time of the cleaning component 230, i.e. the first preset time, is greater than the total running time of the suction component 110, i.e. the second preset time.

[0076] Option 4: Upon receiving a shutdown command and detecting that the cleaning component 230 has been running for a first preset duration, shut down the cleaning component 230. After a delay, shut down the suction assembly 110.

[0077] By taking the above measures, the cleaning component 230 is turned off first, and then the suction component 110 is turned off after a delay, so that the suction component 110 can suck the residual sewage in the suction channel 220 into the sewage tank as much as possible, thus fully avoiding the occurrence of sewage residue in the suction channel 220.

[0078] Combining Scheme 4 with Scheme 1, we can obtain a scheme in which, when a shutdown command is received, both the cleaning component 230 and the suction component 110 are turned on simultaneously. Then, when the running time of the cleaning component 230 reaches the first preset time, the cleaning component 230 is turned off. When the running time of the suction component 110 is detected to reach the second preset time, the suction component 110 is turned off. 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 suction component 110, i.e. the second preset time.

[0079] Combining Scheme 4 and Scheme 2, we obtain a scheme where, upon receiving a stop command, controller 40 first activates cleaning component 230, then activates suction component 110 after a certain interval, followed by a further interval before shutting down cleaning component 230, and finally shutting down suction component 110 after a delay. In this case, the total runtime of cleaning component 230, i.e., the first preset runtime, can be less than, greater than, or equal to the total runtime of suction component 110, i.e., the second preset runtime.

[0080] Option 5: When a shutdown command is received and the running time of the suction component 110 is detected to have reached the second preset time, the suction component 110 is turned off, and then the cleaning component 230 is turned off after a certain delay.

[0081] To facilitate the pivotal connection between the body 10 and the floor brush 20, the suction channel 220 located at the pivot connection is typically designed with a specific structure such as a threaded structure. Furthermore, the suction channel 220 at the pivot connection between the body 10 and the floor brush 20 is a threaded flexible hose. The threaded flexible hose has numerous folds, making it prone to trapping dirt and grime. Due to insufficient power of the suction component 110 or the limitations of the aforementioned suction channel 220 structure, wastewater near the suction port in the suction channel 220 may not be sucked into the wastewater tank and will eventually flow out onto the ground. Therefore, to solve this problem, in this embodiment, the cleaning component 230 is delayed in closing, allowing the rotating cleaning component 230 to absorb the dirt in the suction channel 220 as it exits from the suction port. Alternatively, when dirt flows from the suction channel 220 onto the ground, the rotating cleaning component 230 can absorb the dirt that has flowed onto the ground, thereby preventing dirt from remaining on the already cleaned surface and causing secondary pollution.

[0082] Combining Scheme 5 with Scheme 1, when a shutdown command is received, the controller 40 simultaneously activates the cleaning component 230 and the suction component 110. Then, upon detecting that the suction component 110 has run for a second preset duration, it shuts down the suction component 110. After a delay, the cleaning component 230 is then shut down. In this case, the total running time of the cleaning component 230, i.e., the first preset duration, is greater than the total running time of the suction component 110, i.e., the second preset duration.

[0083] Combining Scheme 5 and Scheme 2, we obtain the following scheme: When a shutdown command is received, the controller 40 controls the cleaning component 230 to start first, then starts the suction component 110 after a certain interval. Afterwards, when the operating time of the suction component 110 reaches the second preset time, the suction component 110 is shut down, and then the cleaning component 230 is shut down after a delay. At this point, the total operating time of the cleaning component 230, i.e., the first preset time, is greater than the total operating time of the suction component 110, i.e., the second preset time.

[0084] As can be seen, the above embodiments achieve different cleaning effects by controlling the cleaning component 230 and the suction component 110 to operate for a delayed time through different control methods. The methods are flexible and varied, but all are easy to control.

[0085] In one embodiment, when the controller 40 receives a stop command while performing the above step S210, it will also control the assist unit 210 to rotate.

[0086] In this embodiment, after receiving a stop command, the cleaning component 230 shuts down after a delay. During the rotation of the cleaning component 230, the floor brush 20 is subjected to the traction force generated by the rotation of the cleaning component 230. To control the movement of the floor brush 20, it is necessary to move it backward to clean any dirt that may remain on the floor, making it easier for the user to store, or to keep the floor brush 20 relatively stationary on the floor to reduce the force required for the user to hold the cleaning device. An assist unit 210 is provided on the floor brush 20. The controller 40 controls the assist unit 210 and the cleaning component 230 to rotate simultaneously, so that the assist unit 210 and the cleaning component 230 form a rotational cooperation to control the operating state of the floor brush 20. Specifically, the principle of controlling the operating state of the floor brush 20 is as follows: the assist unit 210 and the cleaning component 230 apply a corresponding traction force to the floor brush 20 during rotation, and the operating state of the floor brush 20 is controlled based on the magnitude of the traction force.

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

[0088] (1) The cleaning component 230 and the assist unit 210 rotate simultaneously to control the operation of the floor brush 20 so that the floor brush 20 does not move.

[0089] In this embodiment, the cleaning component 230 and the assist unit 210 generate a traction force F during rotation. 11 and F 12 F 11 and F 12 All were applied to the floor brush 20, and F 11 and F 12 They are equal in size but opposite in direction. The floor brush 20 is located in the aforementioned F... 11 and F 12 Under the superposition of these effects, no displacement will occur.

[0090] Through the above measures, when a shutdown command is received, the operation of the cleaning component 230 and the assist unit 210 is controlled so that the floor brush 20 does not move, and the cleaning equipment 1 stops moving after shutdown, which greatly facilitates the user's management of the cleaning equipment 1.

[0091] (2) The cleaning component 230 and the assist unit 210 rotate simultaneously, controlling the operation of the floor brush 20 so that the floor brush 20 moves backward.

[0092] In this embodiment, the cleaning component 230 and the assist unit 210 generate a traction force F during rotation. 21 and F 22 traction force F 21 and F 22 All are applied to the floor brush 20. The traction force F... 21 and F 22The superposition generates a first traction force F, and the direction of the first traction force F is... Figure 6 The middle arrows point in the same direction, and under the action of the first traction force F, the ground brush moves in the 20 direction. Figure 6 Move in the direction indicated by the middle arrow.

[0093] 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 returns to an upright position from a non-upright state. In this case, the user must press the power button on the handle to shut down the cleaning device 1. Afterwards, because the cleaning device 1 is tilted during cleaning, the user needs to manually turn the body 10 from a non-upright state to an upright state for easier storage. In the above embodiment, upon receiving a shutdown command, the floor brush 20 is moved backward by controlling its operation, reducing the resistance when the body 10 returns to an upright position, thus assisting the user and making it easier for the user to return the body 10 to an upright position.

[0094] Furthermore, the suction channel 220 at the pivot connection between the body 10 and the floor brush 20 is a threaded hose. The threaded hose has numerous folds, making it prone to trapping dirt and grime. Due to insufficient power of the suction component 110 or limitations of the suction channel 220 structure, wastewater near the suction port in the suction channel 220 may not be sucked into the wastewater tank and will ultimately flow out onto the ground. In this embodiment, by controlling the operation of the floor brush 20 to move it backward, the cleaning component 230 can absorb the dirt flowing onto the ground, effectively preventing secondary pollution caused by dirt remaining on already cleaned surfaces.

[0095] In one embodiment, after the controller 40 receives a control command while performing the above step S210, it will also perform the following steps:

[0096] Determine whether the fuselage 10 is in an upright position, and then perform different operations based on the determination result.

[0097] In this embodiment, when the controller 40 receives a stop command, it will determine whether the machine body 10 is in such a state. Figure 1 The upright position shown. Specifically, the determination method can be that the trigger switch 30 detects the state of the body 10, and when the body 10 is detected to be in the upright position shown... Figure 1 In the upright position shown, the trigger switch 30 can send a monitoring signal to the controller 40. When the controller 40 receives the monitoring signal, it can determine that the body 10 is in an upright position. Furthermore, when the controller 40 does not receive the monitoring signal, it can determine that the body 10 is in a non-upright position. Furthermore, the trigger switch 30 can be a mechanical structure installed on the floor brush 20, or it can be a micro switch installed on the body 10.

[0098] Once the state of the fuselage 10 is determined, the controller 40 can perform different operations based on the determination result. The specific operating principle is explained in detail below:

[0099] ①If the controller 40 detects that the body 10 is in an upright state, it can control the operation of the ground brush 20 to prevent the ground brush 20 from shifting.

[0100] In one embodiment, the controller 40 can control the operating state of the ground brush 20 to prevent the ground brush 20 from shifting in the following manner:

[0101] The cleaning component 230 and the assist unit 210 are controlled to rotate in two opposite directions. The rotation of the cleaning component 230 generates a second traction force, and the rotation of the assist unit 210 generates a third traction force. The second and third traction forces are equal in magnitude but opposite in direction. Specifically, when the cleaning component 230 rotates clockwise, the assist unit 210 can rotate counterclockwise; or, when the cleaning component 230 rotates counterclockwise, the assist unit 210 can rotate clockwise; or, the cleaning component 230 can rotate alternately clockwise and counterclockwise, and correspondingly, the assist unit 210 also needs to rotate alternately clockwise and counterclockwise.

[0102] For example, such as Figure 7 As shown, when the controller 40 detects that the body 10 is in an upright position, it can control the cleaning component 230 to follow the instructions. Figure 7 As shown, rotating clockwise, the cleaning component 230 produces... Figure 7 The second traction force F5 shown; simultaneously, the controller 40 can control the assist unit 210 according to... Figure 7 As shown, it rotates counterclockwise, at which point the assist unit 210 generates the following: 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 will not be displaced under the superposition of the two traction forces.

[0103] In one embodiment, when the rotation duration of the cleaning component 230 is detected to reach a first preset duration, the controller 40 can control the cleaning component 230 and the assist unit 210 to stop rotating.

[0104] Through the above measures, when the machine body 10 is detected to be in an upright state, the controller 40 controls the operation of the floor brush 20 to prevent the floor brush 20 from shifting, so that the cleaning equipment 1 will no longer move after the machine is stopped, which greatly facilitates the user's management of the cleaning equipment 1.

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

[0106] By taking the above measures, while ensuring that the floor brush 20 does not shift, the rotation speed of the cleaning component 230 is adjusted so that when the machine body 10 is in an upright position after shutdown, the rotation speed of the cleaning component 230 is less than the rotation speed of the cleaning component 230 when performing cleaning operations before shutdown, which facilitates control.

[0107] ②If the controller 40 detects that the body 10 is not in an upright state, it can control the operation of the ground brush 20 to change the body 10 from an upright state to an upright state.

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

[0109] The control brush 20 moves backward, thereby changing the body 10 from a non-upright state to an upright state. Afterward, even when the controller 40 detects that the body 10 is in an upright state, the control brush 20's operation can still prevent it from shifting. Specifically, when the control brush 20 moves backward, it is subjected to a first traction force F that moves backward.

[0110] In this embodiment, a first traction force F is applied to the floor brush 20, and the first traction force F causes the floor brush 20 to move in the direction of... Figure 6 Moving in the direction indicated by the arrow, as the floor brush 20 moves, the body 10 gradually returns to an upright position. When the floor brush 20 moves to... Figure 1 When the target position is reached, the body 10 returns to an upright position. Afterwards, upon detecting that the body 10 has returned to an upright position, the controller 40 can control the operation of the ground brush 20 to prevent it from shifting. Specifically, the principle of preventing the ground brush 20 from shifting is detailed in the above embodiment and will not be repeated here.

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

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

[0113] For example, such as Figure 8 As shown, in this embodiment, the controller 40 can control the cleaning component 230 to perform the following actions: 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 component 230 can rotate in an alternating clockwise and counterclockwise manner, and correspondingly, the assist unit 210 also needs to rotate in an alternating clockwise and counterclockwise manner.

[0120] In one embodiment, when the rotation duration of the cleaning component 230 is detected to reach a first preset duration, the controller 40 can control the cleaning component 230 and the assist unit 210 to stop rotating.

[0121] Through the above measures, if the machine body 10 is not in an upright state when a shutdown command is received, the floor brush 20 is controlled to move backward, thereby restoring the machine body 10 from an upright state to an upright state. Since the user will restore the machine body 10 to an upright state after shutdown for ease of management, the backward movement of the floor brush 20 reduces the resistance when the machine body 10 returns to an upright state, assisting the user and making it easier to restore the machine body 10 to an upright state. Simultaneously, in the above method, when the machine body 10 is in an upright state, the controller 40 can still prevent the floor brush 20 from shifting by controlling its operating state, ensuring that the cleaning equipment 1 does not move after shutdown, greatly facilitating user management of the cleaning equipment 1.

[0122] In the above embodiment ②, the body 10 will undergo a process of changing from a non-upright state to an upright state; wherein, when the body 10 is in an upright state, the controller 40 can control the suction component 110 to operate at a first power; when the body 10 is in a non-upright state, the controller 40 can control the suction component 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 not in an upright position, the sewage in the sewage tank is closer to the suction component 110. When the suction component 110 operates at a lower power, water from the sewage tank can be effectively prevented from entering the suction component 110, thus effectively protecting the suction component 110. In addition, when the machine body 10 is not in an upright position, the operating resistance of the suction component 110 is lower, and sewage can be sucked into the sewage tank with lower power, achieving an energy-saving effect.

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

[0125] By taking the above measures, while ensuring that the floor brush 20 does not shift, the rotation speed of the cleaning component 230 is adjusted to reduce the rotation speed of the cleaning component 230 when it is upright, making it easier to control.
