DETAILED DESCRIPTION

[0055] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0056] In recent years, with the rapid development of cleaning appliance technology, cleaning devices such as floor scrubbers have gradually become indispensable household appliances in people's daily lives. Floor scrubbers have been widely used in places such as residences, offices, and hotels due to their ease of use and mobility and good cleaning effects. For light or heavy dirt, it is necessary to adjust the light cleaning or deep cleaning mode accordingly when cleaning with the cleaning device to control the cleaning strength of the cleaning device.

[0057] In the related art, infrared is usually used to identify the degree of dirtiness, and the sensor sends a control signal to automatically adjust the rotation speed of the cleaning structure to control the cleaning strength of the cleaning device. However, in the cleaning device using the related art, infrared recognition is difficult to respond quickly, the recognition error is large and the frequency of recognition failure is high. The user cannot actively control the rotation speed of the cleaning structure to control the cleaning strength of the cleaning device, and the cleaning effect and user experience are poor. In addition, the setting of infrared equipment and sensors makes the internal structure of the cleaning device complicated and the manufacturing cost is high.

[0058] Based on this, the exemplary embodiment of the present disclosure provides a cleaning device, wherein the cleaning liquid is supplied to the rotating cleaning structure through the cleaning liquid supply part, and the cleaning operation of the surface to be cleaned can be realized by rotating the rotating cleaning structure around a preset axis, and the handheld part can drive the cleaning part to move the position to adjust the cleaning area or repeatedly clean the cleaning area. The rotation speed and rotation direction of the rotating cleaning structure are controlled by the operating part, so that the user can actively control the cleaning force of the cleaning device when operating the operating part, the adjustment response speed is fast, the cleaning effect is improved, and the user experience is enhanced.

[0059] In an exemplary embodiment, reference Figure 1 As shown, a cleaning device is provided, the cleaning device includes a cleaning part 10, a cleaning liquid supply part, a handheld part 20 and an operating part 30, the cleaning part 10 includes a rotating cleaning structure 11, and the rotating cleaning structure 11 can rotate around a preset axis to perform a cleaning operation on the surface to be cleaned. The cleaning liquid supply part is used to supply cleaning liquid to the rotating cleaning structure 11. The handheld part 20 is connected to the cleaning part 10, and the handheld part 20 is used to drive the cleaning part 10 to move. The operating part 30 is arranged on the handheld part 20, and the operating part 30 is used to control the rotation speed of the rotating cleaning structure 11, or the operating part 30 is used to control the rotation direction of the rotating cleaning structure 11, or the operating part 30 is used to control the rotation speed and rotation direction of the rotating cleaning structure 11.

[0060] The cleaning part 10 may include, for example, a housing 12 and a rotating cleaning structure 11, wherein the rotating cleaning structure 11 is disposed in the housing 12 and partially exposed outside the housing 12. The rotating cleaning structure 11 may be, for example, cylindrical, and when the cleaning device is used, the surface of the rotating cleaning structure 11 may contact the surface to be cleaned, so that the rotating cleaning structure 11 may perform a cleaning operation on the surface to be cleaned when rotating around a preset axis.

[0061] The cleaning liquid supply part may, for example, include a clean water tank and a delivery pipe. The cleaning liquid in the clean water tank can be delivered to the rotating cleaning structure 11 through the delivery pipe, so that when the rotating cleaning structure 11 contacts the surface to be cleaned and rotates around a preset axis, it carries the cleaning liquid to enhance the cleaning effect. The cleaning liquid may, for example, be water, detergent, etc.

[0062] The handheld portion 20 is connected to the cleaning portion 10. The user can move the cleaning portion 10 by holding the handheld portion 20 to change the surface to be cleaned or repeatedly clean the surface to be cleaned. The operating portion 30 is arranged on the handheld portion 20. The operating portion 30 can control the rotation speed and rotation direction of the rotating cleaning structure 11. The user can operate the operating portion 30. For example, when there is heavy dirt on the surface to be cleaned, the user can control the rotating cleaning structure 11 to rotate at a higher rotation speed through the operating portion 30 for deep cleaning. When there is light dirt on the surface to be cleaned, the user can control the rotating cleaning structure 11 to rotate at a lower rotation speed through the operating portion 30 for light cleaning. When the rotating cleaning structure 11 rotates at a higher rotation speed and the dirt on the surface to be cleaned is still difficult to remove, the user can also control the rotating cleaning structure 11 to rotate in different rotation directions through the operating portion 30 to clean from different directions.

[0063] In this embodiment, the cleaning liquid is supplied to the rotating cleaning structure 11 through the cleaning liquid supply part, and the cleaning operation of the surface to be cleaned can be realized by rotating the rotating cleaning structure 11 around the preset axis, and the handheld part 20 can drive the cleaning part 10 to move the position to adjust the cleaning area or repeatedly clean the cleaning area. The rotation speed and rotation direction of the rotating cleaning structure 11 are controlled by the operating part 30, so that the user can actively control the cleaning force of the cleaning device when operating the operating part 30, and the adjustment response speed is fast, which improves the cleaning effect and enhances the user experience. In addition, the overall structure of the cleaning device is simple, which reduces the manufacturing cost of the cleaning device.

[0064] In some embodiments, the operating part 30 may include, for example, a knob and a knob base, and the knob can be rotated relative to the knob base to control the rotation speed of the rotating cleaning structure 11, or to control the rotation direction of the rotating cleaning structure 11, or to control the rotation speed and rotation direction of the rotating cleaning structure 11.

[0065] In other embodiments, reference Figure 2 As shown, the operating part 30 includes a slide rail 40 and a slide key 50. The slide rail 40 is arranged on the hand-held part 20, and the slide key 50 is arranged in the slide rail 40. The slide key 50 can slide relative to the slide rail 40 to control the rotation speed of the rotating cleaning structure 11, or control the rotation direction of the rotating cleaning structure 11, or control the rotation speed and rotation direction of the rotating cleaning structure 11.

[0066] The slide rail 40 is arranged at the top of the hand-held part 20 and extends in a straight line. A slide key 50 that can slide relative to the slide rail 40 is arranged in the slide rail 40. When the user holds the hand-held part 20, the slide key 50 can be pushed to slide by fingers. When the slide key 50 slides on the slide rail 40, the rotation speed and rotation direction of the rotating cleaning structure 11 can be controlled as the position of the slide key 50 changes. Exemplarily, the initial position of the slide key 50 can be, for example, in the middle position of the slide rail 40. When the slide key 50 is pushed to slide toward the two ends of the slide rail 40, the rotation speed of the rotating cleaning structure 11 gradually increases. When the slide key 50 is located between the initial position and one end of the slide rail 40, the rotation direction of the rotating cleaning structure 11 is opposite to the rotation direction of the rotating cleaning structure 11 when the slide key 50 is located between the initial position and the other end of the slide rail 40.

[0067] In this embodiment, a slide rail 40 is provided on the hand-held part 20, and a slide key 50 that can slide relative to the slide rail 40 is provided in the slide rail 40, so that the rotation speed and rotation direction of the rotating cleaning structure 11 can be controlled by sliding the slide key 50, thereby realizing that the operating part 30 controls the rotation speed and rotation direction of the rotating cleaning structure 11, so that the user can actively control the cleaning force of the cleaning device when operating the operating part 30, the adjustment response speed is fast, and the cleaning effect is improved. In addition, the operating part 30 composed of the slide rail 40 and the slide key 50 has a simple structure and is easy to operate, thereby improving the user experience.

[0068] In some embodiments, the cleaning device also includes a control unit, which is used to control the rotation speed of the rotating cleaning structure 11 according to the position of the sliding key 50, or control the rotation direction of the rotating cleaning structure 11, or control the rotation speed and rotation direction of the rotating cleaning structure 11.

[0069] Exemplarily, the control unit may include a circuit board, for example, which may obtain the position information of the sliding key 50 on the slide rail 40, and control the rotation speed and rotation direction of the rotating cleaning structure 11 according to the position information. The control unit may be connected to the driving device of the rotating cleaning structure 11, and control the rotating cleaning structure 11 to rotate at a rotation speed and rotation direction corresponding to the position according to the position of the sliding key 50.

[0070] In this embodiment, the control unit can control the rotation speed and rotation direction of the rotating cleaning structure 11 according to the position of the sliding key 50, so as to control the rotation speed and rotation direction of the rotating cleaning structure 11 by sliding the sliding key 50 relative to the slide rail 40, so that the user can actively control the cleaning force of the cleaning device when operating the operating unit 30, the adjustment response speed is fast, the cleaning effect is improved, and the user experience is enhanced.

[0071] In some embodiments, the operating unit also includes a position sensor, which can monitor the position of the slide key 50 in real time to obtain the position information of the slide key 50. The control unit is used to control the rotation speed of the rotating cleaning structure 11 according to the position information obtained by the position sensor, or control the rotation direction of the rotating cleaning structure 11, or control the rotation speed and rotation direction of the rotating cleaning structure 11.

[0072] In other embodiments, the operating unit 30 also includes a variable resistor, the variable end of the variable resistor is connected to the slide key 50, and the control unit is used to control the rotation speed of the rotating cleaning structure 11 according to the resistance between the variable end and the fixed end of the variable resistor, or control the rotation direction of the rotating cleaning structure 11, or control the rotation speed and rotation direction of the rotating cleaning structure 11.

[0073] The variable resistor includes a variable end and a fixed end. For example, the resistance between the variable end and the fixed end of the variable resistor can be connected to the detection circuit. When the position of the sliding key 50 changes, the resistance between the variable end and the fixed end of the variable resistor, that is, the resistance connected to the detection circuit, changes accordingly. Therefore, the resistance between the variable end and the fixed end of the variable resistor can represent the position of the sliding key 50, and the rotation speed and rotation direction of the rotating cleaning structure 11 can be controlled according to the resistance between the variable end and the fixed end of the variable resistor detected by the detection circuit.

[0074] In this embodiment, by setting a variable resistor and connecting the variable end of the variable resistor to the slide key 50, different positions of the slide key 50 can correspond to different resistances between the variable end and the fixed end of the variable resistor, and the rotation speed and rotation direction of the rotating cleaning structure 11 can be controlled according to the resistance between the variable end and the fixed end of the variable resistor, so that the user can actively control the cleaning force of the cleaning device when operating the operating part 30, the adjustment response speed is fast, the cleaning effect is improved, and the user experience is improved. The setting of the variable resistor can quickly and accurately obtain the position information of the slide key 50, which is convenient for the control part to control the rotation speed and rotation direction of the rotating cleaning structure 11, and improves the control accuracy of the cleaning force of the cleaning device.

[0075] In some embodiments, reference Figure 2 and Figure 3 As shown, a groove 21 is provided on the hand-held part 20, and the slide rail 40 includes tracks 41 provided on the first side wall and the second side wall of the groove 21, and the first side wall and the second side wall are arranged opposite to each other; a slide groove 51 cooperating with each track 41 is provided on the slide key 50.

[0076] A groove 21 is provided at the top of the hand-held part 20. The cross-sectional shape of the groove 21 may be, for example, a rectangle. The groove 21 includes a first side wall and a second side wall that are arranged opposite to each other. Two tracks 41 are arranged opposite to each other on the first side wall and the second side wall. The extension direction of the track 41 is the same as the extension direction of the groove 21. The cross-sectional shape of the track 41 may be, for example, a rectangle. The two tracks 41 constitute the slide rail 40. A slide groove 51 that cooperates with each track 41 is provided on the slide key 50. The slide groove 51 may be, for example, provided in the middle of the slide key 50 along the height direction of the slide key 50. For example, when the cross-sectional shape of the track 41 is a rectangle, the cross-sectional shape of the slide groove 51 is also a rectangle. When the slide key 50 cooperates with the slide rail 40, the track 41 can be embedded in the slide groove 51, so that the slide key 50 can slide relative to the slide rail 40.

[0077] In this embodiment, a track 41 is provided on the first side wall and the second side wall of the groove 21 on the hand-held part 20, and a slide groove 51 cooperating with the track 41 is provided on the slide key 50, so that the slide key 50 can slide relative to the slide rail 40 formed by the track 41, and then the rotation speed and rotation direction of the rotating cleaning structure 11 can be controlled as the position of the slide key 50 changes, so that the user can actively control the cleaning force of the cleaning device when operating the operating part 30, the adjustment response speed is fast, the cleaning effect is improved, and the operating part 30 formed by the slide rail 40 and the slide key 50 has a simple structure and is easy to operate, thereby improving the user experience.

[0078] In some embodiments, reference Figure 2 As shown, the operating part 30 also includes a first return spring 60, which extends along the sliding direction of the sliding key 50, one end of the first return spring 60 abuts against the third side wall of the groove 21, and the other end of the first return spring 60 abuts against the sliding key 50. The first return spring 60 is used to abut against the fourth side wall of the groove 21 when the sliding key 50 is not subjected to external force.

[0079] The operating portion 30 further includes a first return spring 60 extending in the sliding direction of the slide key 50, and the two ends of the first return spring 60 respectively abut against the third side wall of the groove 21 and the slide key 50. The abutment position of the first return spring 60 and the slide key 50 can be, for example, below the slide groove 51 along the height direction of the slide key 50. The third side wall is arranged opposite to the fourth side wall. When the slide key 50 is not subjected to external force, that is, the slide key 50 is in the initial position, the slide key 50 abuts against the fourth side wall. When the user pushes the slide key 50 to move in the direction away from the fourth side wall, the length of the first return spring 60 becomes shorter and is in a compressed state, so that the first return spring 60 applies an elastic force to the slide key 50 in the direction close to the fourth side wall. When the user no longer pushes the slide key 50, the slide key 50 returns to the initial position and abuts against the fourth side wall, thereby realizing the reset of the slide key 50.

[0080] In this embodiment, a first return spring 60 extending along the sliding direction of the slide key 50 is provided in the groove 21, and the two ends of the first return spring 60 are respectively abutted against the third side wall and the slide key 50, so that an elastic force in the direction close to the fourth side wall can be provided to the slide key 50, so that the slide key 50 is abutted against the fourth side wall when not subject to external force, thereby realizing automatic resetting of the slide key 50 after the external force is removed, thereby improving the user experience.

[0081] In other embodiments, the operating part 30 also includes a second return spring and a third return spring, and the second return spring and the third return spring both extend along the sliding direction of the slide key 50, one end of the second return spring abuts against the third side wall of the groove 21, and the other end of the second return spring abuts against the slide key 50, one end of the third return spring abuts against the fourth side wall of the groove 21, and the other end of the third return spring abuts against the slide key 50, and the second return spring and the third return spring are used to be located in the middle of the slide rail 40 when the slide key 50 is not subjected to external force.

[0082] The operating part 30 also includes a second return spring and a third return spring, both extending along the sliding direction of the sliding key 50. The two ends of the second return spring are respectively abutted against the third side wall and one side of the sliding key 50, and the two ends of the third return spring are respectively abutted against the fourth side wall and the other side of the sliding key 50. The abutment position of the second return spring and the third return spring and the sliding key 50 can be, for example, below the sliding groove 51 along the height direction of the sliding key 50.

[0083] The third side wall is arranged opposite to the fourth side wall. When the slide key 50 is not subjected to external force, that is, the slide key 50 is in the initial position, the slide key 50 is located in the middle of the slide rail 40. When the user pushes the slide key 50 to move toward the third side wall, the length of the second return spring becomes shorter and is in a compressed state, and the length of the third return spring becomes longer and is in a tensile state, so that the second return spring and the third return spring simultaneously apply elastic force to the slide key 50 in the direction away from the third side wall, so that when the user no longer pushes the slide key 50, the slide key 50 returns to the initial position, thereby realizing the reset of the slide key 50.

[0084] When the user pushes the slide key 50 to move toward the fourth side wall, the length of the second return spring becomes longer and is in a tensile state, and the length of the third return spring becomes shorter and is in a compressive state, so that the second return spring and the third return spring simultaneously apply an elastic force to the slide key 50 in a direction away from the fourth side wall, so that when the user no longer pushes the slide key 50, the slide key 50 returns to its initial position, thereby achieving the reset of the slide key 50.

[0085] In this embodiment, a first return spring 60 and a second return spring extending along the sliding direction of the slide key 50 are arranged in the groove 21, and the two ends of the second return spring are respectively abutted against the third side wall and one side of the slide key 50, and the two ends of the third return spring are respectively abutted against the fourth side wall and the other side of the slide key 50, thereby providing elastic force to the slide key 50, so that the slide key 50 is located in the middle of the slide rail 40 when not subject to external force, thereby realizing automatic resetting of the slide key 50 after the external force is removed, thereby improving the user experience.

[0086] In some embodiments, reference Figure 3 As shown, an anti-slip structure 52 is provided on the top of the sliding key 50 .

[0087] The top of the sliding key 50 is provided with an anti-slip structure 52. For example, the anti-slip structure 52 may be Figure 3 The anti-skid grooves shown are arranged at intervals and the extending direction of each anti-skid groove is perpendicular to the sliding direction of the sliding key 50. The anti-skid structure 52 can also be a plurality of anti-skid protrusions, which are arranged at intervals and the extending direction of each anti-skid protrusion is perpendicular to the sliding direction of the sliding key 50.

[0088] In this embodiment, an anti-slip structure 52 is provided on the top of the sliding key 50, so that the user can contact the anti-slip structure 52 when pushing the sliding key 50. The anti-slip structure 52 increases the contact area and friction force with the user's fingers, thereby preventing the sliding key 50 from detaching due to relative sliding between the user's fingers and the sliding key 50 when the user wants to push the sliding key 50. This ensures the stability of the user's control over the movement of the sliding key 50 and improves the user experience.

The connecting part 70 can be, for example, a cavity structure, and a containing space is provided in the connecting part 70, and the cleaning liquid supply part is provided in the containing space in the connecting part 70.

[0096] In this embodiment, the connection between the handheld part 20 and the cleaning part 10 is realized by providing the connecting part 70, so that the handheld part 20 can drive the cleaning part 10 to move the position to change the surface to be cleaned or repeatedly clean the surface to be cleaned, and the overall height of the cleaning device is increased, so that the height of the handheld part 20 and the operating part 30 is roughly the same as the height of the user's hand in the natural state, which is convenient for the user to hold the handheld part 20 and operate the operating part 30. In addition, the setting of the connecting part 70 also provides a storage space for the cleaning liquid supply part and other components that need to be built in.

The connection angle of the connecting part 70 and the cleaning part 10 can be adjusted accordingly according to the different heights of the users or the different cleaning scenes, thereby adjusting the hand-held part 20 and the operating part 30 to a suitable height, making it easier for the user to hold the hand-held part 20 and operate the operating part 30, thereby improving the user experience.

[0099] In some embodiments, reference Figure 1As shown, a roller 80 is provided on a side of the cleaning portion 10 away from the rotating cleaning structure 11 , and the axis of the roller 80 is parallel to the preset axis.

[0100] A roller 80 is provided on one side of the cleaning portion 10 away from the rotating cleaning structure 11. For example, two rollers 80 are provided. The two rollers 80 can be respectively provided on both sides of the connection position between the cleaning portion 10 and the connecting portion 70. The two rollers 80 are coaxially arranged, and the axes of the two rollers 80 are parallel to the preset axis. When the cleaning device is used, the rotating cleaning structure 11 contacts the surface to be cleaned, and the roller 80 can also contact the ground where the surface to be cleaned is located. When the user holds the handheld portion 20 to move, the roller 80 can roll relative to the ground, thereby driving the cleaning portion 10 to move.

[0101] In this embodiment, by arranging a roller 80 on the side of the cleaning part 10 away from the rotating cleaning structure 11, the roller 80 can be in contact with the ground and roll relative to the ground when the user holds the handheld part 20 to move, thereby realizing the movement of the position of the cleaning part 10, making it convenient to change the surface to be cleaned or repeatedly clean the surface to be cleaned.

[0102] In an exemplary embodiment, reference Figure 4 As shown, a control method for a cleaning device is provided, the control method comprising:

[0103] S100 : In response to an operation of an operating part of a cleaning device, determining a target rotation direction and / or a target rotation speed of a rotating cleaning structure of the cleaning device.

[0104] In step S100, when the user performs an operation on the operating part 30, such as pushing the sliding key 50 to slide, the target rotation direction of the rotating cleaning structure 11 is determined in response to the user's operation on the operating part 30, or the target rotation speed of the rotating cleaning structure 11 is determined. Alternatively, the target rotation direction and target rotation speed of the rotating cleaning structure 11 are determined.

[0105] S200: Control the rotating cleaning structure to operate in a target rotation direction and / or a target rotation speed.

[0106] In step S200, for example, the control unit may control the rotating cleaning structure 11 to run in a target rotation direction, or control the rotating cleaning structure 11 to run at a target rotation speed, or control the rotating cleaning structure 11 to run in a target rotation direction and a target rotation speed.

[0107] In this embodiment, in response to the operation of the operating part 30 of the cleaning device, the target rotation direction and target rotation speed corresponding to the rotating cleaning structure 11 are determined, and the rotating cleaning structure 11 is controlled to operate at the target rotation direction and target rotation speed, thereby realizing the control of the operation of the rotating cleaning structure 11. The user can perform different operations on the operating part 30 of the cleaning device according to different requirements of the target rotation direction and target rotation speed to realize active control of the cleaning force of the cleaning device, with fast adjustment response speed, improved cleaning effect, and enhanced user experience.

[0108] In some embodiments, reference Figure 5 As shown, in response to the operation of the operating part 30 of the cleaning device, determining the target rotation direction and / or target rotation speed of the rotating cleaning structure 11 of the cleaning device includes:

[0109] S110, determining the position information of the sliding key of the operating part.

[0110] In step S110, the position information of the slide key 50 of the operating part 30 is determined, and the position information can represent the position of the slide key 50 in the slide rail 40. The determination of the position information can be achieved, for example, by a variable resistor, so that different positions of the slide key 50 correspond to different resistances between the variable end and the fixed end of the variable resistor, and the position information can be determined based on the resistance between the variable end and the fixed end of the variable resistor.

[0111] S120: Determine a target rotation direction and / or a target rotation speed of the rotating cleaning structure according to the position information.

[0112] In step S120 , the target rotation direction of the rotating cleaning structure 11 is determined according to the determined position information, or the target rotation speed of the rotating cleaning structure 11 is determined, or the target rotation direction and the target rotation speed of the rotating cleaning structure 11 are determined.

[0113] In this embodiment, by determining the position information of the sliding key 50 of the operating part 30, the target rotation direction and target rotation speed of the rotating cleaning structure 11 can be determined according to the position information, thereby providing a basis for subsequent control of the operation of the rotating cleaning structure 11, so that the user can actively control the cleaning force of the cleaning device when operating the operating part 30, the adjustment response speed is fast, the cleaning effect is improved, and the user experience is enhanced.

[0114] In some embodiments, reference Figure 6 As shown, according to the position information of the sliding key 50 of the operating part 30, the target rotation direction and / or the target rotation speed of the rotating cleaning structure 11 is determined, including:

[0115] S121. When the position information indicates that the sliding key is located between the initial position and the first end of the slide rail, determine that the target rotation direction of the rotating cleaning structure is a first direction.

[0116] S122. When the position information indicates that the sliding key is located between the initial position and the second end of the slide rail, determine that the target rotation direction of the rotating cleaning structure is a second direction, which is opposite to the first direction.

[0117] In step S121 and step S122, the initial position of the sliding key 50 on the slide rail 40 may be, for example, located in the middle of the slide rail 40. When the position information indicates that the sliding key 50 is located between the initial position and the first end of the slide rail 40, the target rotation direction of the rotating cleaning structure 11 is determined to be the first direction, which may be, for example, the direction in which the rotating cleaning structure 11 rotates clockwise relative to the surface to be cleaned. When the position information indicates that the sliding key 50 is located between the initial position and the second end of the slide rail 40, the target rotation direction of the rotating cleaning structure 11 is determined to be the second direction, which may be, for example, the direction in which the rotating cleaning structure 11 rotates counterclockwise relative to the surface to be cleaned.

[0118] In this embodiment, the position information indicates that the sliding key 50 is located between the initial position and the first end of the slide rail 40 or between the initial position and the second end of the slide rail 40, and the target rotation direction corresponding to the rotating cleaning structure 11 can be determined to be the first direction or the second direction, thereby achieving the determination of the target rotation direction and providing a basis for the subsequent control of the operation of the rotating cleaning structure 11. The user can slide the sliding key 50 to different positions according to the requirements of different target rotation directions, so that the user can actively control the cleaning force of the cleaning device when operating the operating part 30, and the adjustment response speed is fast, which improves the cleaning effect and enhances the user experience.

[0119] In other embodiments, the position information includes distance information between the current position and the initial position of the sliding key 50, and the target rotation direction and / or target rotation speed of the rotating cleaning structure 11 are determined based on the position information, including: determining the target rotation speed of the rotating cleaning structure 11 based on the distance information, the greater the distance represented by the distance information, the greater the target rotation speed.

[0120] Among them, the distance information can represent the distance between the current slide key 50 and the initial position. According to the distance information, the target rotation speed of the rotating cleaning structure 11 can be determined. The distance information represents that the larger the distance between the current position and the initial position of the slide key 50, the greater the distance the user pushes the slide key 50, and the greater the determined target rotation speed.

[0121] Exemplarily, when the sliding key 50 is located at the initial position in the middle of the slide rail 40, the target rotation speed of the rotating cleaning structure 11 can be, for example, 0. When the sliding key 50 slides from the initial position to the first end or the second end of the slide rail 40, the target rotation speed of the rotating cleaning structure 11 gradually increases until the sliding key 50 slides to the first end or the second end, and the target rotation speed of the rotating cleaning structure 11 is the maximum. When the user needs to rotate the cleaning structure 11 to run at a higher rotation speed, the sliding key 50 can be slid in a direction away from the initial position. When the user needs to rotate the cleaning structure 11 to run at a lower rotation speed, the sliding key 50 can be slid in a direction close to the initial position. When the user needs to stop the rotating cleaning structure 11, the sliding key 50 can be no longer contacted to reset the sliding key 50 to the initial position through the reset spring.

[0122] In this embodiment, the target rotation speed of the rotating cleaning structure 11 is determined according to the distance information included in the position information, and the determination of the target rotation speed is realized, which provides a basis for the subsequent control of the operation of the rotating cleaning structure 11. The larger the distance represented by the distance information, the larger the determined target rotation speed. The user can slide the sliding key 50 to different positions according to the requirements of different target rotation speeds, so that the user can actively control the cleaning force of the cleaning device when operating the operating part 30, and the adjustment response speed is fast, which improves the cleaning effect and enhances the user experience.

[0123] In some other embodiments, when the slide key 50 is located at the initial position in the middle of the slide rail 40, the target rotation speed of the rotating cleaning structure 11 can be, for example, a preset initial speed. When the slide key 50 slides from the initial position to the first end of the slide rail 40, the target rotation speed of the rotating cleaning structure 11 gradually increases. When the slide key 50 slides from the initial position to the second end of the slide rail 40, the target rotation speed of the rotating cleaning structure 11 gradually decreases.

[0124] In some embodiments, the operating unit 30 further includes a variable resistor, and the variable end of the variable resistor is connected to the sliding key 50. Figure 7 As shown, determining the position information of the sliding key 50 of the operating portion 30 includes:

[0125] S111 , detecting resistance information between a variable end and a fixed end of a variable resistor.

[0126] In step S111, the variable resistor includes a variable end and a fixed end. The resistance information between the variable end and the fixed end of the variable resistor can be detected by a detection circuit. For example, the resistance between the variable end and the fixed end of the variable resistor can be connected to the detection circuit. When the position of the sliding key 50 changes, the resistance between the variable end and the fixed end of the variable resistor, that is, the resistance connected to the detection circuit, changes accordingly.

[0127] S112. Determine position information according to the resistance information.

[0128] In step S112, when the position of the sliding key 50 changes, the resistance between the variable end and the fixed end of the variable resistor, i.e., the resistance connected to the detection circuit, changes accordingly. Therefore, the resistance information between the variable end and the fixed end of the variable resistor can represent the position of the sliding key 50 in the slide rail 40, and the corresponding position information can be determined according to the resistance information.

[0129] In this embodiment, by setting a variable resistor and detecting the resistance information between the variable end and the fixed end of the variable resistor, the position can be determined according to the resistance information, and the position information is determined, which provides a basis for determining the subsequent target rotation direction and target rotation speed. When the user operates the operating part 30, the cleaning force of the cleaning device can be actively controlled, the adjustment response speed is fast, the cleaning effect is improved, and the user experience is enhanced. The setting of the variable resistor can quickly and accurately obtain the position information of the sliding key 50, and improve the control accuracy of the cleaning force of the cleaning device.

[0130] In other embodiments, after detecting the resistance information between the variable end and the fixed end of the variable resistor, the target rotation speed of the rotating cleaning structure 11 can also be directly determined based on the resistance information. Exemplarily, the resistance ratio of the resistance information to the total resistance information of the variable resistor can be determined, and the resistance ratio is the ratio of some variable resistors connected to the test circuit to all variable resistors, so that the sliding key has different resistance ratios when it is located at different positions. Then, the determined resistance ratio is multiplied by the maximum rotation speed of the rotating cleaning structure 11, and the product is used to determine the target rotation speed of the non-rotating cleaning structure, so that a larger resistance information can correspond to a larger target rotation speed, thereby realizing the determination of the target rotation speed and providing a basis for the subsequent control of the operation of the rotating cleaning structure 11.

[0131] In an exemplary embodiment, reference Figure 8 As shown, a control method for a cleaning device is provided, the control method comprising:

[0132] S10, detecting resistance information between a variable end and a fixed end of a variable resistor;

[0133] S20, determining position information according to the resistance information;

[0134] S30, when the position information indicates that the sliding key 50 is located between the initial position and the first end of the slide rail 40, determining that the target rotation direction of the rotating cleaning structure 11 is the first direction;

[0135] S40, when the position information indicates that the sliding key 50 is located between the initial position and the second end of the slide rail 40, determining that the target rotation direction of the rotating cleaning structure 11 is the second direction;

[0136] S50, determining a target rotation speed of the rotating cleaning structure 11 according to the distance information;

[0137] S60, controlling the rotating cleaning structure 11 to run in the target rotating direction and the target rotating speed.

[0138] In this embodiment, in response to the operation of the operating part 30 of the cleaning device, the target rotation direction and target rotation speed corresponding to the rotating cleaning structure 11 are determined, and the rotating cleaning structure 11 is controlled to operate at the target rotation direction and target rotation speed, thereby realizing the control of the operation of the rotating cleaning structure 11. The user can perform different operations on the operating part 30 of the cleaning device according to different requirements of the target rotation direction and target rotation speed to realize active control of the cleaning force of the cleaning device, with fast adjustment response speed, improved cleaning effect, and enhanced user experience.
