[0044] The technical solution of the present disclosure will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described implementation is a part of the implementation of the present disclosure, rather than all the implementations. Based on the implementation in the present disclosure, all other implementations obtained by ordinary technicians in the field without creative work are within the scope of protection of the present disclosure. In addition, the technical features involved in the different implementations of the present disclosure described below can be combined with each other as long as they do not conflict with each other.

[0045] With the continuous development of smart home technology, smart cleaning equipment is increasingly entering people's lives, such as sweeping robots, sweeping and mopping robots, floor scrubbers, etc. Among them, hand-held wireless floor scrubbers have gradually become popular in households due to their convenience and water-saving advantages.

[0046] During the use of a floor scrubber, the user is required to push the machine back and forth to complete the washing and mopping of the floor. Since the floor scrubber itself has a large weight and the water tank needs to be filled with water during use, which further increases the weight, the user will feel more strenuous during the long cleaning process. In order to improve the convenience of the floor scrubber, power wheels are often added to the floor brush of the floor scrubber.

[0047] For example Figure 1 The schematic diagram of the structure of a floor scrubber is shown. When the user pushes the floor scrubber forward and backward to clean the floor, the power-assisted wheel can convert the sliding friction between the floor brush and the floor into rolling friction, thereby making the floor scrubber relatively easier to use.

[0048] In the related art, the power-assisted wheels of floor scrubbers are divided into two types: non-driven and motor-driven. The non-driven method means that the power-assisted wheels are not driven by a motor and can only passively rotate when the user pushes the floor scrubber. This method has limited power-assisted effect on the user when using the floor scrubber, and the user still feels more laborious during a long cleaning process.

[0049] The motor drive mode means that the power-assisted wheel has a driving motor, and the output power of the motor is used to drive the power-assisted wheel to rotate actively. Since the power-assisted wheel can autonomously generate traction in the forward and backward directions, it is easier for users to use. However, the autonomous control of the power-assisted wheel of the floor scrubber requires a complex algorithm. On the one hand, it is necessary to identify the user's movement trend of pushing forward or pulling backward, and on the other hand, the speed of the power-assisted wheel needs to adapt to the user's movement rhythm of pushing forward or pulling backward, resulting in poor power-assisted effect of the electric power-assisted wheel. For example, the floor scrubber cannot promptly identify the user's movement changes of pushing forward or pulling backward. During the user's pulling backward, the power-assisted wheel still outputs traction force to push forward, making it more difficult for the user to use.

[0050] Based on the defects of the above-mentioned related technologies, the embodiments of the present disclosure provide a cleaning device and a control method thereof, aiming to provide an efficient control method for the power-assisting wheel of a floor scrubber, accurately control the power-assisting device, make the user use the floor scrubber more labor-saving, and improve the user experience.

[0051] It should be noted that the cleaning equipment in the embodiments of the present disclosure may include any equipment suitable for providing an assisting device, such as a hand-held floor scrubber, a sweeper, a vacuum cleaner, etc. In the following embodiments of the present disclosure, the cleaning equipment will be described using a floor scrubber as an example, but those skilled in the art will understand that the cleaning equipment provided by the present disclosure is not limited to this.

[0052] In some embodiments, the cleaning device provided by the present disclosure includes a body, a power assist device, and a control device.

[0053] The body refers to the main structure of the cleaning device, including the shell structure and the corresponding electrical structure. For example, in some embodiments of the present disclosure, the cleaning device is a floor scrubber, and the body of the floor scrubber may include hardware structures such as a floor brush assembly, a handle, and a water tank, and may also include electrical structures such as a motor, a water pump, and a circuit board. Those skilled in the art can understand this, and the present disclosure will not elaborate on it.

[0054] The power-assisting device refers to a structural component that assists the movement of the cleaning device. For example, in some embodiments, the power-assisting device is disposed on the main body of the cleaning device, and includes a power-assisting wheel and a driving component that drives the power-assisting wheel to move.

[0055] The power-assisting wheel can be arranged on the main body, and its function is to convert the sliding friction between the cleaning device and the ground into rolling friction when the cleaning device moves relative to the ground, thereby reducing the friction between the cleaning device and the ground, making the force applied by the user smaller and more labor-saving.

[0056] The driving assembly is connected to the power-assisted wheel, and its function is to drive the power-assisted wheel to rotate. In some embodiments, the driving assembly may include a motor and a transmission mechanism, and the transmission mechanism is connected to the output shaft of the motor, so that the rotation of the output shaft of the motor can be applied to the power-assisted wheel through the transmission mechanism, thereby driving the power-assisted wheel to rotate.

[0057] In some embodiments of the present disclosure, the drive assembly can drive the power-assisted wheel to rotate forward or reverse, thereby providing forward or backward traction for the cleaning device. This is explained below in the present disclosure and will not be described in detail here.

[0058] The control device refers to the relevant structure and functional modules used to control the movement of the power-assisting device. In the embodiment of the present disclosure, the control device includes a touch screen and a controller arranged on the handle of the cleaning device. The touch screen can provide touch signals for interacting with the user, so that the controller can control the operation of the driving component according to the touch signal, and the driving component can drive the power-assisting wheel to move.

[0059] Figure 2 The structural block diagram of the cleaning device in some embodiments of the present disclosure is shown below. Figure 2 Provide explanation.

[0060] like Figure 2 As shown, in the embodiment of the present disclosure, the control device includes a touch screen 603 and a controller, and the controller includes a processor 601 and a memory 602 , wherein the processor 601 , the memory 602 and the touch screen 603 establish a communicative connection between any two of them through a bus 604 .

[0061] The processor 601 may be any type of processor having one or more processing cores, and may perform single-thread or multi-thread operations, and may be used to parse instructions to perform operations such as acquiring data, performing logical operations, and issuing operation processing results.

[0062] The memory 602 may include volatile and / or non-volatile computer-readable storage media, such as at least one disk storage device, flash memory device, etc. The memory 602 may have a program storage area for storing non-volatile software programs, non-volatile computer executable programs, and modules for the processor 601 to call so that the processor 601 executes corresponding method steps to implement the relevant functions described below in the present disclosure. The memory 602 may also include a volatile random storage medium, or a storage part such as a hard disk, as a data storage area, for storing the operation processing results and data output by the processor 601.

[0063] The touch screen 603 can be arranged on the handle of the cleaning device, and the touch screen 603 can output and display the corresponding touch operation interface, and the user can perform the corresponding touch operation on the touch operation interface, so that the touch screen 603 generates a corresponding touch signal by detecting the user's touch operation. The touch signal can be sent to the processor 601 through the bus 604, so that the processor 601 controls the driving component 605 to work according to the received touch signal. It can be understood that when the driving component 605 is working, it can drive the power wheel 606 to move, so as to provide traction for the cleaning device to move forward or backward.

[0064] In some embodiments, a virtual button may be output and displayed on the touch screen 603, so that the user can trigger a corresponding touch signal by clicking the virtual button. In other embodiments, a virtual wheel may be output and displayed on the touch screen 603, so that the user can trigger a corresponding touch signal by manipulating the virtual wheel. This is described in the following embodiments of the present disclosure.

[0065] Combination Figure 1 It can be seen from the application scenarios of floor scrubbers that when users use floor scrubbers to clean the floor, they often need to push and pull the floor scrubber repeatedly, that is, the floor scrubber needs to move forward and backward repeatedly. Relying on sensors to autonomously identify movement trends often has obvious lags, so the self-driven power-assisted wheel control algorithm is very complex and has poor accuracy. For example, when the user uses the floor scrubber to switch from the forward state to the backward state, the control algorithm is relatively lagging and often cannot switch the power-assisted wheel from the forward motion to the backward motion in time, resulting in the continued output of traction in the forward direction. The user needs to provide greater pulling force to pull the floor scrubber, making the cleaning process more laborious.

[0066] In the disclosed embodiment, by setting a touch screen on the handle of the cleaning device, the user can manually control the power-assisting device through the touch screen, and the response speed of the power-assisting wheel motion state switching is faster, and there is no lag delay, which can be well adapted to the user's cleaning rhythm and is more labor-saving to use. Moreover, since the touch screen is set on the handle, the interactive operation of the touch screen is completely in line with the use habits of the floor scrubber. The user can achieve precise control of the power-assisting device without additional operation, thereby improving the control effect. In addition, the movement speed and steering of the power-assisting device can also be adjusted through touch control, further enriching the control method for the power-assisting device and improving the power-assisting effect of the cleaning equipment.

[0067] From the above, it can be seen that in the embodiment of the present disclosure, the touch screen is used to interact with the user to realize the control of the power-assisting device, reduce the response delay of the power-assisting device when the motion state of the equipment is switched, and improve the control effect of the power-assisting device. Moreover, the touch screen is set on the handle, and the user can realize precise control of the power-assisting device without additional operation, and can also accurately adjust the movement speed and steering of the power-assisting device, thereby improving the power-assisting effect and cleaning efficiency of the cleaning equipment.

[0068] Figures 3 to 7 The schematic diagram of the structure of the cleaning device in some embodiments of the present disclosure is shown below. Figures 3 to 7 A cleaning device according to an embodiment of the present disclosure will be described.

[0069] like Figure 3 As shown, in this example, the cleaning device takes a floor scrubber as an example. The main body of the cleaning device includes a handle 1 and a floor brush assembly 2. The handle 1 is movably connected to the floor brush assembly 2. The movable connection can be, for example, hinged. When the user pushes and pulls the floor scrubber, the user only needs to provide forward or forward and backward force to easily push or pull back the floor brush through the hinge between the handle 1 and the floor brush assembly 2.

[0070] like Figure 4 As shown, the active connection position between the floor brush assembly 2 and the handle 1 is provided with a booster wheel 606, which is provided on the left and right sides of the floor brush assembly 2. It is worth noting that Figure 4 In the example, a power-assisting wheel 606 is provided on each of the left and right sides of the floor brush assembly 2. In other embodiments, a power-assisting wheel group may be provided on each of the left and right sides of the floor brush assembly 2, and each power-assisting wheel group includes one or more power-assisting wheels 606.

[0071] For example, in one example, two power-assisting wheels 606 may be provided on the left and right sides of the floor brush assembly 2, that is, the floor brush assembly 2 includes a total of four power-assisting wheels. Of course, those skilled in the art can understand that the power-assisting wheel set may also include a larger number of power-assisting wheels, which will not be described in detail in this disclosure.

[0072] In the disclosed embodiment, the power-assisted wheel group on one side of the floor brush assembly 2 is defined as the first wheel group, and the power-assisted wheel group on the other side is defined as the second wheel group. The first wheel group and the second wheel group are independently controlled by the driving assembly, that is, the rotation speed and direction of the first wheel group can be different from those of the second wheel group.

[0073] Of course, it can be understood that the floor brush assembly 2 is also provided with other corresponding hardware structures or functional modules, for example, see Figure 2 As shown, the front end of the floor brush assembly 2 is also provided with a roller brush assembly 609. After the floor scrubber is turned on, the roller brush assembly 609 continuously rotates and rubs against the ground to remove the stains attached to the ground. A negative pressure assembly 608 is also provided at the bottom of the floor brush assembly 2. The negative pressure assembly 608 may include a negative pressure fan to provide negative pressure suction to suck the stains removed by the roller brush assembly 609 into the garbage bin inside the floor brush assembly 2. A water pump assembly 607 is also provided inside the floor brush assembly 2. The water pump assembly 607 can absorb water from the water tank on the handle 1 to achieve mopping of the floor through the roller brush assembly 609.

[0074] As for the structure and related principles of each functional module of the floor scrubber, those skilled in the art can undoubtedly understand and fully implement them by referring to the relevant technologies, and the present disclosure will not elaborate on them.

[0075] In the embodiments of the present disclosure, see Figure 3 , Figure 5 As shown, the lower end of the handle 1 is movably connected to the floor brush assembly 2, and the upper end of the handle 1 is bent to form a gripping portion 110, and the gripping portion 110 serves to facilitate user gripping.

[0076] See also Figure 5 As shown, combined with the actual scenario of users using the floor scrubber, it can be known that when the user holds the gripping portion 110 of the handle 1, the user often holds the gripping portion 110 with the palm. At this time, the thumb can be naturally placed on the area A outside the gripping portion 110, which is most in line with the user's natural force state.

[0077] Therefore, in the embodiment of the present disclosure, when the user naturally holds the gripping portion 110 of the handle 1, the area A that the thumb contacts can be defined as the first area A. The position of the first area A can be as follows: Figure 5 The positions indicated in are used as reference.

[0078] In the example disclosed herein, the touch screen 603 is disposed on the first area A, that is, the touch screen 603 is disposed in the area where the grip portion 110 contacts the user's thumb. In the embodiment disclosed herein, the touch screen 603 is disposed in the first area A, which can perfectly fit the operation scenario when the user uses the floor scrubber, and combined with the control method, the precise control of the power assist device can be achieved, which is described in detail below.

[0079] In some embodiments, the touch operation interface displayed and output by the touch screen 603 may be an operation interface including virtual buttons, that is, the touch screen 603 is configured to output and display virtual buttons, and the user can control the power assist device by clicking the virtual buttons.

[0080] exist Figure 6 In the exemplary implementation, the operation interface of the touch screen 603 may be as shown in the figure, and virtual buttons are output and displayed on the touch screen 603, and the virtual buttons include a first button for controlling the power assist device and a second button for controlling functions related to the cleaning device. Figure 6 The direction keys shown may include direction keys for four directions: up, down, left, and right. The second key is Figure 6 The "On / Off" and "Function" buttons shown.

[0081] Taking the second button as an example, when the user clicks the "on / off" button on the touch screen 603, the touch screen 603 can detect the corresponding touch signal, so that the controller controls the cleaning device to turn on / off according to the touch signal. When the user clicks the "function" button on the touch screen 603, the touch screen 603 can detect the corresponding touch signal, so that the controller controls the cleaning device to switch functions according to the touch signal, and the function switching can include, for example, switching of cleaning modes.

[0082] As for the first button, when the user clicks the "↑" button on the touch screen 603, the touch screen 603 can detect the corresponding touch signal, so that the controller determines that the direction of movement of the power-assisting device is forward according to the touch signal, and the controller can control the driving component to drive the power-assisting wheel to move forward, and the power-assisting wheel can drive the cleaning device forward. When the user clicks the "↓" button on the touch screen 603, the touch screen 603 can detect the corresponding touch signal, so that the controller determines that the direction of movement of the power-assisting device is backward according to the touch signal, and the controller can control the driving component to drive the power-assisting wheel to move backward, and the power-assisting wheel can drive the cleaning device backward.

[0083] Through the above process, the user can use the touch screen 603 to control the power-assisting device, so that the power-assisting wheel provides traction in the forward or backward direction, thereby helping the user to use the cleaning device. Figure 6 In the implementation manner, the touch screen 603 can also be used to control the steering of the power-assisted wheel.

[0084] It is understandable that in actual floor washing operations, in addition to operating the floor washing machine forward and backward, after cleaning a certain floor, the user also needs to operate the floor washing machine to switch to another floor to continue cleaning, thus requiring the floor washing machine to complete the reversing operation. Figure 6In the implementation manner, the user can realize the steering of the power-assisted wheels through the virtual buttons on the touch screen 603, thereby realizing automatic steering of the floor scrubber.

[0085] For example, see Figure 6 As shown, when the user clicks the "←" button on the touch screen 603, the touch screen 603 can detect the corresponding touch signal, so that the controller determines that the movement direction of the power-assisting device is a left turn according to the touch signal, and the controller can control the drive component to achieve a left turn. When the user clicks the "→" button on the touch screen 603, the touch screen 603 can detect the corresponding touch signal, so that the controller determines that the movement direction of the power-assisting device is a right turn according to the touch signal, and the controller can control the drive component to achieve a right turn.

[0086] In some embodiments, the process of the controller controlling the steering of the power-assisted wheel includes: determining the movement direction of the power-assisted device based on the touch signal of the touch screen, determining the differential parameters of the first wheel group and the second wheel group according to the movement direction, and controlling the driving component to drive the first wheel group and the second wheel group to move respectively according to the differential parameters.

[0087] Combined with the above Figure 4 As shown, a first wheel group and a second wheel group are respectively provided on the left and right sides of the floor brush assembly. To complete the steering of the floor brush assembly, the rotation speed difference between the first wheel group and the second wheel group can be utilized.

[0088] For example, in the aforementioned example, after determining that the direction of movement of the power-assisting device is a left turn, the controller can determine the speed difference between the first wheel group and the second wheel group according to the direction of movement, and the speed difference is the differential parameter. After determining the differential parameter between the first wheel group and the second wheel group, the motor of the drive assembly can output the corresponding power according to the differential parameter, and respectively control the differential movement of the first wheel group and the second wheel group to achieve a left turn. For example, in one example, the speed of the power-assisting wheel on the right side of the floor brush assembly can be controlled to be greater than the speed of the power-assisting wheel on the left side, so that the floor brush assembly turns left; for example, in another example, the power-assisting wheel on the right side of the floor brush assembly can be controlled to rotate forward, and the power-assisting wheel on the left side of the floor brush assembly can be controlled to rotate backward, so that the floor brush assembly turns left. The principle of turning right is similar to that of turning left, and those skilled in the art can understand it by referring to the above description, and the present disclosure will not repeat it.

[0089] Through the above process, we can know that using Figure 6 The virtual buttons of the touch screen 603 shown can not only realize the forward and backward control of the power-assisting device, but also realize the steering control of the power-assisting device, which greatly improves the convenience of users when using the floor scrubber for a long time.

[0090] like Figure 7As shown, in some other embodiments, the touch screen 603 can also be configured to display a virtual wheel 4, which is equivalent to a virtual joystick. The user can control the direction of the virtual wheel 4 by sliding and touching, and the touch screen 603 can detect the user's touch signal on the virtual wheel 4.

[0091] It is worth noting that, since the virtual wheel 4 can slide arbitrarily within a circular range, the touch signal for the virtual wheel 4 detected by the touch screen 603 may include a sliding distance signal and a sliding direction signal. The sliding direction signal refers to the direction in which the user slides the virtual wheel 4, for example Figure 7 In the example, it includes 8 directions, including up, down, left, right, upper left, upper right, lower left, and lower right. The sliding distance signal refers to the distance that the user slides the virtual wheel 4 in a certain direction. For example, the sliding distance signal generated by the user sliding the wheel upward with a small amplitude is smaller than the sliding distance signal generated by the user sliding the wheel upward with a large amplitude.

[0092] Therefore, in the embodiment of the present disclosure, the control of the power assisting device also includes two aspects: one is to control the movement direction of the power assisting device according to the sliding direction signal; the other is to control the movement speed of the power assisting device according to the sliding distance signal.

[0093] For example, in one example, the user operates the virtual wheel 4 to slide in a certain direction, and the touch screen 603 can detect the corresponding touch signal, and the controller determines the sliding direction signal and the sliding distance signal according to the touch signal.

[0094] In the embodiment of the present disclosure, the correspondence between the sliding distance signal and the movement speed of the power-assisting device can be pre-set, so that after determining the sliding distance signal, the movement speed corresponding to the power-assisting device can be determined according to the correspondence, and the drive component is controlled to output the corresponding power according to the movement speed, so that the power-assisting wheel rotates according to the movement speed.

[0095] In the embodiment of the present disclosure, the process of the controller controlling the movement direction of the power-assisted wheel includes: determining the movement direction of the power-assisted device based on the sliding direction signal of the virtual wheel, determining the differential parameters of the first wheel group and the second wheel group according to the movement direction, and controlling the driving component to drive the first wheel group and the second wheel group to move respectively according to the differential parameters.

[0096] The process of controlling the steering of the power-assisted wheel based on the sliding direction signal of the virtual wheel 4 is similar to the above Figure 6 The implementation modes are similar, and those skilled in the art may refer to the foregoing, and the present disclosure will not elaborate on them.

[0097] Through the above process, we can know that using Figure 7The virtual wheel 4 of the touch screen 603 shown can not only realize the forward and backward control of the power-assisting device, but also realize the steering control of the power-assisting device, which greatly improves the convenience of users when using the floor scrubber for a long time.

[0098] In some embodiments, it is also possible to further Figure 7 The "on / off" and "function" buttons are integrated into the virtual wheel 4, thereby eliminating the virtual buttons for "on / off" and "function". For example, in one example, the touch screen 603 can detect a click signal for the virtual wheel 4. When the user clicks the virtual wheel 4 in the off state, the cleaning device can be turned on and run according to the click signal; when the user clicks the virtual wheel 4 in the on state, the corresponding cleaning function can be switched according to each click signal; when the user double-clicks the virtual wheel 4 in the on state, the cleaning device can be turned off, etc.

[0099] In some embodiments, see Figure 3 and Figure 4 As shown, in the floor scrubber of the example disclosed in the present invention, the main body also includes a water tank, which can be arranged on the handle 1, and the floor brush assembly includes a shell, a roller brush is arranged at the front end of the shell, and a negative pressure assembly is arranged at the bottom of the shell, etc. Those skilled in the art can realize it by referring to the relevant technology, and the present disclosure will not elaborate on this.

[0100] From the above, it can be seen that in the disclosed embodiment, the touch screen is used to interact with the user to realize the control of the power-assisting device, reduce the response delay of the power-assisting device when the equipment moves in different states, and improve the control effect of the power-assisting device. Moreover, the touch screen is set on the handle, and the user can realize accurate control of the power-assisting device without additional operation, and can also accurately adjust the movement speed and steering of the power-assisting device, thereby improving the power-assisting effect and cleaning efficiency of the cleaning equipment. In addition, not only can the forward and backward control of the power-assisting device be realized, but also the steering control of the power-assisting device can be realized, which greatly improves the convenience of users when using the floor scrubber for a long time.

[0101] On the basis of the above-mentioned embodiments, the present disclosure provides a control method for a cleaning device. The method can be applied to the cleaning device of any of the above-mentioned embodiments, and the processing is executed by the processor of the cleaning device to realize the control of the power assisting device of the cleaning device.

[0102] like Figure 8 As shown, in some embodiments, the control method of the cleaning device of the present disclosure example includes:

[0103] S810: In response to detecting a touch signal generated by a touch screen provided on the cleaning device, generate a control signal for a power assisting device of the cleaning device based on the touch signal.

[0104] S820: Control the power assist device to operate based on the control signal to provide power assist to the cleaning device.

[0105] In combination with the above, it can be known that during the operation of the user using the cleaning device, when the user does not perform any operation on the touch screen 603, the controller controls the driving component not to work, so that the power-assisted wheel does not rotate.

[0106] Combination Figure 7 As shown, when the user controls the virtual wheel 4 on the touch screen 603 to slide, the controller can detect and obtain the corresponding touch signal.

[0107] In some embodiments, the touch signal may include a sliding direction signal and a sliding distance signal, wherein the sliding direction signal indicates the sliding direction of the virtual wheel 4 , such as “forward”, “left”, etc., and the sliding distance signal indicates the sliding distance of the virtual wheel 4 .

[0108] For example, in one example, the user operates the virtual wheel 4 to slide in a certain direction, and the touch screen 603 can detect the corresponding touch signal, and the controller determines the sliding direction signal and the sliding distance signal according to the touch signal.

[0109] In the disclosed embodiment, the controller can determine the movement direction of the power-assisting device according to the sliding direction signal. At the same time, the corresponding relationship between the sliding distance signal and the movement speed of the power-assisting device can be preset, so that after determining the sliding distance signal, the movement speed corresponding to the power-assisting device can be determined according to the corresponding relationship. Then, the controller can control the driving component according to the movement direction and movement speed, drive the power-assisting wheel 606 to rotate forward, and generate power to drive the scrubber to move.

[0110] In the embodiment of the present disclosure, the process of the controller controlling the movement direction of the power-assisted wheel includes: determining the movement direction of the power-assisted device based on the sliding direction signal of the virtual wheel, determining the differential parameters of the first wheel group and the second wheel group according to the movement direction, and controlling the driving component to drive the first wheel group and the second wheel group to move respectively according to the differential parameters.

[0111] The process of controlling the steering of the power-assisted wheel based on the sliding direction signal of the virtual wheel 4 is similar to the above Figure 6 The implementation modes are similar, and those skilled in the art may refer to the foregoing, and the present disclosure will not elaborate on them.

[0112] In some embodiments, the control method of the present disclosure further includes:

[0113] In response to detecting a first touch signal generated by double-clicking the touch screen, the power on / off state of the cleaning device is switched based on the first touch signal.

[0114] In one example, when the cleaning device is in the off state, the user can quickly double-click the touch screen 603, so that the controller can detect the first touch signal of the touch screen 603 being double-clicked, thereby controlling the cleaning device to turn on. Conversely, when the cleaning device is in the on state, the user can quickly double-click the touch screen 603, so that the controller can detect the first touch signal of the touch screen 603 being double-clicked, thereby controlling the cleaning device to turn off.

[0115] In some embodiments, the control method of the present disclosure further includes:

[0116] When the cleaning device is in a powered-on state, in response to detecting a second touch signal generated by a single click on the touch screen, the working gear of the cleaning device is switched based on the second touch signal.

[0117] Similar to the above, when the cleaning device is turned on, the user can click the touch screen 603, so that the controller can detect the second touch signal of the touch screen 603 being clicked, thereby switching the working gear of the cleaning device. For example, in one example, the cleaning device defaults to the "standard" cleaning gear when it is turned on. When the user clicks the touch screen 603, the controller detects the second touch signal, so that the controller can control the cleaning device to switch from the "standard" cleaning gear to the "strong" cleaning gear according to the second touch signal.

[0118] Of course, those skilled in the art will appreciate that the “on / off” and “gear switching” functions may also be implemented using, for example, Figure 6 and Figure 7 The virtual key implementation shown is not described in detail in this disclosure.

[0119] From the above, it can be seen that in the disclosed embodiment, the touch screen is used to interact with the user to realize the control of the power-assisting device, reduce the response delay of the power-assisting device when the equipment moves in different states, and improve the control effect of the power-assisting device. Moreover, the touch screen is set on the handle, and the user can realize accurate control of the power-assisting device without additional operation, and can also accurately adjust the movement speed and steering of the power-assisting device, thereby improving the power-assisting effect and cleaning efficiency of the cleaning equipment. In addition, not only can the forward and backward control of the power-assisting device be realized, but also the steering control of the power-assisting device can be realized, which greatly improves the convenience of users when using the floor scrubber for a long time.

[0120] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the embodiments. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
