Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, in particular to cleaning equipment. Background Art

[0002] The cleaning power of a floor scrubber is mainly reflected in the friction between the roller brush and the ground, and the friction is composed of two factors: one is the friction between the roller brush and the ground, and the other is the roughness of the roller brush. The roller brushes used in related technologies all use a uniform material, polymer fluff roller brushes, which results in a certain degree of roughness of the roller brush. However, due to the weight limitation of the floor scrubber itself, coupled with the trend of existing floor scrubbers becoming increasingly lightweight, the weight of the floor scrubber has been further reduced. The combination of these two reasons makes it more difficult for floor scrubbers to clean stubborn stains on the ground. Therefore, when users use floor scrubbers, they often need to clean back and forth multiple times in the face of stubborn stains. Sometimes, the solidified stains on the ground cannot be removed and other tools need to be used to remove them.

[0003] To increase the positive pressure exerted by a floor scrubber on the ground, related technologies typically place the clean water tank on the floor brush to increase friction. However, since placing the clean water tank on the floor brush only adds limited weight and simply lowers the center of gravity of the entire machine, the pressure exerted on the ground is limited, making it incapable of completely removing stubborn stains. Summary of the Invention

[0004] In view of this, the present invention provides a cleaning device to solve the problem of removing stubborn stains on the ground.

[0005] In a first aspect, the present invention provides a cleaning device comprising:

[0006] Floor brush, including bottom shell and roller brush;

[0007] A boosting structure is provided on the bottom shell, and the boosting structure includes a driving component and a supporting component connected to the bottom shell. The driving component can drive the supporting component to move and enable the supporting component to have a first position and a second position. In the second position, the force applied to the bottom shell by the supporting component is greater than the force applied to the bottom shell by the supporting component in the first position.

[0008] Beneficial effect: By arranging a boosting structure on the bottom shell, the boosting structure includes a driving component and a supporting component. The driving component can drive the supporting component to move and make the supporting component have a first position and a second position. In the second position, the force applied by the supporting component to the bottom shell is greater than the force applied by the supporting component to the bottom shell in the first position. Therefore, in the second position, the overall pressure applied to the ground by the floor brush is greater. When it is necessary to clean stubborn stains on the ground, the driving component is operated to drive the supporting component to the second position. The overall pressure applied to the ground by the floor brush is greater, thereby increasing the friction between the roller brush and the ground, which can effectively remove stubborn stains.

[0009] In an optional embodiment, the boosting structure further includes a connecting rod, a sleeve rod and a spring, the connecting rod being capable of rotating under the drive of the driving component, one end of the connecting rod being hinged to the supporting component, and the other end slidingly engaged with the sleeve rod, the end of the sleeve rod away from the connecting rod being arranged on the adapter of the floor brush, the spring being arranged between the sleeve rod and the connecting rod, and when in the second position, the angle between the connecting rod and the supporting component is an obtuse angle, the spring is compressed, and the compression force of the spring is transmitted to the supporting component through the connecting rod.

[0010] Beneficial effect: The connecting rod can rotate under the drive of the driving component. One end of the connecting rod is hinged to the supporting component, and the other end is slidingly matched with the sleeve rod. Therefore, when the connecting rod rotates under the drive of the driving component, the supporting component is driven to rotate. The connecting rod moves relative to the sleeve rod when rotating. Since the sleeve rod is arranged on the adapter of the floor brush at one end away from the connecting rod, the position of the sleeve rod remains stationary or the movement amplitude is very small, so that the connecting rod compresses the spring. The angle between the connecting rod and the supporting component is an obtuse angle. The compression force of the spring is transmitted to the supporting component through the connecting rod, increasing the pressure on the bottom shell, thereby increasing the friction between the roller brush and the ground, which can effectively remove stubborn stains.

[0011] In an optional embodiment, the driving component includes a driving motor and a cam, one side of the cam is connected to the output shaft of the driving motor, and the other side of the cam is connected to the connecting rod.

[0012] Beneficial effects: The driving component includes a driving motor and a cam. One side of the cam is connected to the output shaft of the driving motor, and the other side of the cam is connected to the connecting rod. The connecting rod is driven to rotate by the cam. Since one end of the connecting rod is constrained by the supporting component, the setting of the cam can ensure that the connecting rod can rotate.

[0013] In an optional embodiment, the sleeve rod is a hollow structure, the connecting rod includes a first connecting section and a second connecting section, the second connecting section extends into the sleeve rod, one end of the spring is against the sleeve rod, and the other end is against the first connecting section.

[0014] Beneficial effect: The connecting rod includes a first connecting section and a second connecting section, the second connecting section extends into the sleeve rod, one end of the spring is against the sleeve rod, and the other end is against the first connecting section, which facilitates the assembly of the spring, and the compression force of the spring can be transmitted to the supporting component through the first connecting section.

[0015] In an optional embodiment, the cleaning device includes a body, the floor brush is connected to the body via a corner assembly, the corner assembly is connected to the floor brush via a bearing, the adapter includes the bearing, and the end of the sleeve rod away from the connecting rod is provided with an arc portion adapted to the outer surface of the bearing, and the elastic force of the spring can keep the arc portion in contact with the bearing.

[0016] Beneficial Effects: The angle between the body and the floor brush can be adjusted, making it easier for users to use. The angle assembly is connected to the floor brush via a bearing. The adapter includes a bearing. The end of the sleeve rod away from the connecting rod is provided with an arc portion that matches the outer surface of the bearing. The elastic force of the spring can keep the arc portion in contact with the bearing. The bearing is used to position the sleeve rod without adding additional components. In addition, when the spring is compressed, the bearing exerts a reaction force on the spring, causing it to tilt downward. This force is then transmitted to the support component through the connecting rod, thereby increasing the pressure applied by the support component to the bottom shell.

[0017] In an optional embodiment, the cleaning device includes a controller and an angle detection component, the angle detection component can detect the angle between the body and the floor brush, the controller is communicatively connected with the angle detection component and the driving component, and can control the driving component to rotate a corresponding angle according to the angle detected by the angle detection component.

[0018] Beneficial effect: Due to the different torsion angles of the fuselage relative to the floor brush, the pressure on the bottom shell of the floor brush is different. When the fuselage is upright, its positive pressure is the largest. By setting an angle detection component, the angle detection component can detect the angle between the fuselage and the floor brush. The controller controls the driving component to rotate the corresponding angle according to the angle detected by the angle detection component, so that the pressure of the floor brush on the ground can be constant.

[0019] In an optional embodiment, the bottom shell is provided with a limiting structure, and the limiting structure is used to enable the supporting component to rotate between the first position and the second position.

[0020] Beneficial effect: By setting the limiting structure, the support component can only rotate between the first position and the second position, which makes it easier to control the rotation direction.

[0021] In an optional embodiment, the cleaning device has a normal mode and a strong mode. In the normal mode, the supporting component is in the first position. In the strong mode, the supporting component is in the second position.

[0022] Beneficial Effects: In Powerful Mode, the overall pressure exerted by the floor brush on the ground increases, resulting in increased friction between the roller brush and the ground, effectively removing stubborn stains. If the brush remains in Powerful Mode, the support component remains in the second position, and the floor brush is pressurized, increasing friction between the roller brush, scraper, and the ground, leading to accelerated wear. Worn roller brushes can lead to increased water stains, decreased cleaning effectiveness, and other issues, while replacing new roller brushes can increase user costs. The scraper strips exert increased friction on the ground over time. Although scrapers are generally made of soft rubber, the high pressure can cause scratches and partial marks. This can also lead to increased aging and wear of the scraper strips, resulting in an uneven contact surface. This can result in streaks of water after the entire machine is in operation, impacting the user experience. Therefore, a Normal Mode setting is selected. Once stubborn stains have been removed, the drive component can be activated, switching to Normal Mode and driving the support component to the first position. At this point, the overall pressure exerted by the floor brush on the ground is relatively reduced, reducing wear on the roller brush.

[0023] In an optional embodiment, the cleaning device includes a handle, and the handle is provided with a button, and the button can switch between the normal mode and the strong mode when pressed.

[0024] Beneficial effect: Users can switch between normal mode and strong mode by operating buttons, which is convenient for user operation.

[0025] In an optional embodiment, the floor brush is provided with a dirt detection module, and the cleaning device includes a controller, which is communicatively connected with the dirt detection module and the driving component, and can control the driving component to drive the supporting component to move to the second position when the dirt detection module detects a preset degree of dirt.

[0026] Beneficial effect: By setting up the dirt detection module, the controller can control the driving component to drive the supporting component to move to the second position when the dirt detection module detects a preset degree of dirt, which is more intelligent.

[0027] In an optional embodiment, when the dirt detection module detects a preset degree of dirt, the controller controls the driving component to drive the supporting component to move to the second position, and drives the supporting component to move to the first position after maintaining the second position for a preset period of time.

[0028] Beneficial effect: When the dirt detection module detects a preset degree of dirt, the controller controls the driving component to drive the supporting component to move to the second position, and drives the supporting component to move to the first position after maintaining the second position for a preset period of time, thereby avoiding wear of the roller brush caused by the supporting component being in the second position for a long time.

[0043] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0046] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] The cleaning power of a floor scrubber is mainly reflected in the friction between the roller brush and the ground, and the friction is composed of two factors: one is the friction between the roller brush and the ground, and the other is the roughness of the roller brush. The roller brushes used in related technologies all use a uniform material, polymer fluff roller brushes, which results in a certain degree of roughness of the roller brush. However, due to the weight limitation of the floor scrubber itself, coupled with the trend of existing floor scrubbers becoming increasingly lightweight, the weight of the floor scrubber has been further reduced. The combination of these two reasons makes it more difficult for floor scrubbers to clean stubborn stains on the ground. Therefore, when users use floor scrubbers, they often need to clean back and forth multiple times in the face of stubborn stains. Sometimes, the solidified stains on the ground cannot be removed and other tools need to be used to remove them.

[0048] To increase the positive pressure exerted by a floor scrubber on the ground, related technologies typically place the clean water tank on the floor brush to increase friction. However, since placing the clean water tank on the floor brush only adds limited weight and simply lowers the center of gravity of the entire machine, the pressure exerted on the ground is limited, making it incapable of completely removing stubborn stains.

[0049] The following combination Figures 1 to 8 , describing embodiments of the present invention.

[0050] According to an embodiment of the present invention, on the one hand, a cleaning device is provided, including a floor brush 1 and a pressurizing structure.

[0051] Among them, the floor brush 1 includes a bottom shell 101 and a roller brush 103; the boosting structure is arranged on the bottom shell 101, and the boosting structure includes a driving component and a support component 403 connected to the bottom shell 101. The driving component can drive the support component 403 to move and make the support component 403 have a first position and a second position. When in the second position, the force applied by the support component 403 to the bottom shell 101 is greater than the force applied by the support component 403 to the bottom shell 101 when in the first position.

[0052] In this embodiment, a boosting structure is provided on the bottom shell 101, and the boosting structure includes a driving component and a support component 403. The driving component can drive the support component 403 to move and make the support component 403 have a first position and a second position. In the second position, the force applied by the support component 403 to the bottom shell 101 is greater than the force applied by the support component 403 to the bottom shell 101 in the first position. Therefore, in the second position, the pressure applied by the floor brush 1 to the ground as a whole is greater. When it is necessary to clean stubborn stains on the ground, the driving component is operated to drive the support component 403 to the second position. The pressure applied by the floor brush 1 to the ground as a whole is greater, thereby increasing the friction between the roller brush 103 and the ground, which can effectively remove stubborn stains.

[0053] In addition, if the support component 403 is always in the second position and the floor brush 1 is in a pressurized state, the friction between the roller brush 103, the scraper strip 104, and the ground will increase, resulting in accelerated wear. When the roller brush 103 is worn, it will cause many problems such as increased water stains and reduced cleaning effect. Replacing a new roller brush 103 will increase the user's usage costs. The scraper strip 104 will increase the friction on the ground over a long period of time. Although the scraper strip 104 is generally made of soft rubber material, the high pressure will have a certain probability of scratching the ground, causing partial scratches. It will also cause the scraper strip 104 to age more severely, wear more severely, and the contact surface to be uneven. After the whole machine is running, it will cause streaks of water marks, affecting the user experience. Therefore, the pressurized state cannot be used for a long time. After the stubborn stains are removed, the drive component can be activated to drive the support component 403 to the first position. At this time, the pressure applied to the ground by the floor brush 1 as a whole is relatively reduced, which can reduce the wear on the roller brush 103.

[0054] It should be noted that the cleaning device in this embodiment is a floor scrubber, which generally consists of three integral parts: a handle 3, a body 2, and a floor brush 1. The handle 3 has a display 302 and buttons 301, which primarily serve as controls and are the part held during operation. The body 2 houses a wastewater tank 201, a fresh water tank 202, a battery, a suction fan, a speaker, and other components.

[0055] The floor brush 1 is mainly composed of a roller brush 103, a roller brush motor 106, a water pump 109, a scraper 105, a scraper bar 104, a power-assisted wheel 107, a bottom shell 101 and an upper shell 102, a corner assembly 108 and other components.

[0056] Function of roller brush 103: The surface of roller brush 103 is covered with fluff, and roller brush 103 rotates to clean the ground and drags solid and liquid garbage into the air suction port.

[0057] Function of the roller brush motor 106: The roller brush 103 is sleeved on the outside of the roller brush motor 106. The motor drives the roller brush 103 to rotate and controls the speed of the roller brush 103.

[0058] The function of the water pump 109 is to pump clean water from the clean water tank 202 of the floor scrubber to the water outlet of the floor brush 1 to wet and clean the roller brush 103. The water pump 109 is specifically arranged on the floor brush 1.

[0059] Function of the scraper 105: fixed on the upper shell 102, in contact with the roller brush 103, and scraping off the solid garbage and sewage on the roller brush 103.

[0060] Function of the scraper 104: fixed on the lower shell of the base, it can scrape away dirt and water stains on the ground.

[0061] Function of power-assisted wheel 107: It has a built-in motor that can control the front and rear drive and provide front and rear power assistance according to user usage.

[0062] The bottom shell 101 and the upper shell 102 are mainly used to fix and protect the parts of the floor brush 1.

[0063] Function of the corner component 108: the upper part is connected to the fuselage 2, and the lower part is fixed to the upper and lower shells of the base and can rotate.

[0064] In one embodiment, the boosting structure also includes a connecting rod 404, a sleeve rod 405 and a spring 406. The connecting rod 404 can rotate under the drive of the driving component. One end of the connecting rod 404 is hinged to the support component 403, and the other end is slidingly matched with the sleeve rod 405. The end of the sleeve rod 405 away from the connecting rod 404 is arranged on the adapter of the floor brush 1, and the spring 406 is arranged between the sleeve rod 405 and the connecting rod 404. In the second position, the angle between the connecting rod 404 and the support component 403 is an obtuse angle, the spring 406 is compressed, and the compression force of the spring 406 is transmitted to the support component 403 through the connecting rod 404.

[0065] In this embodiment, the connecting rod 404 can rotate under the drive of the driving component. One end of the connecting rod 404 is hinged to the support component 403, and the other end is slidably matched with the sleeve rod 405. Therefore, when the connecting rod 404 rotates under the drive of the driving component, it drives the support component 403 to rotate. The connecting rod 404 moves relative to the sleeve rod 405 when rotating. Since the sleeve rod 405 is arranged on the adapter of the floor brush 1 at one end away from the connecting rod 404, the position of the sleeve rod 405 remains stationary or the movement amplitude is very small, so that the connecting rod 404 compresses the spring 406. The angle between the connecting rod 404 and the support component 403 is an obtuse angle. The compression force of the spring 406 is transmitted to the support component 403 through the connecting rod 404, increasing the pressure on the bottom shell 101, thereby increasing the friction between the roller brush 103 and the ground, which can effectively remove stubborn stains.

[0066] Specifically in one embodiment, when the support component 403 is in the first position, the angle between the support component 403 and the connecting rod 404 is an acute angle, and when the support component 403 is in the second position, the angle between the support component 403 and the connecting rod 404 is an obtuse angle. Therefore, the compression force of the spring 406 is transmitted obliquely downward to the connecting rod 404, and then transmitted obliquely downward to the support component 403 through the connecting rod 404, thereby increasing the pressure exerted by the support component 403 on the bottom shell 101.

[0067] Specifically in one embodiment, Figure 7 and Figure 8 The adapter is provided on the rear side of the support component 403, and the first end of the support component 403 is hinged to the bottom shell 101. When the support component 403 is in the first position, the second end of the support component 403 is tilted forward. When the support component 403 is in the second position, the second end of the support component 403 is tilted backward.

[0068] In an embodiment not shown in the figures, when the adapter is arranged on the front side of the support component 403, when the support component 403 is in the first position, the second end of the support component 403 is tilted backward, and when the support component 403 is in the second position, the second end of the support component 403 is tilted forward.

[0069] In one embodiment, the driving component includes a driving motor 401 and a cam 402 . One side of the cam 402 is connected to the output shaft of the driving motor 401 , and the other side of the cam 402 is connected to the connecting rod 404 .

[0070] In this embodiment, the driving component includes a driving motor 401 and a cam 402. One side of the cam 402 is connected to the output shaft of the driving motor 401, and the other side of the cam 402 is connected to the connecting rod 404. The connecting rod 404 is driven to rotate by the cam 402. Since one end of the connecting rod 404 is constrained by the supporting component 403, the setting of the cam 402 can ensure that the connecting rod 404 can rotate.

[0071] Specifically in one embodiment, the drive motor 401 is fixed to the bottom shell 101 by two screws. Four ribs are provided on the bottom shell 101 to limit its position. The drive motor 401 can rotate forward and backward with a rotation angle of 90°. Of course, the rotation angle can also be changed according to the specific size.

[0072] In one embodiment, the sleeve rod 405 is a hollow structure, the connecting rod 404 includes a first connecting section 4041 and a second connecting section 4042, the second connecting section 4042 extends into the sleeve rod 405, one end of the spring 406 is against the sleeve rod 405, and the other end is against the first connecting section 4041.

[0073] In this embodiment, the connecting rod 404 includes a first connecting section 4041 and a second connecting section 4042. The second connecting section 4042 extends into the sleeve rod 405. One end of the spring 406 is against the sleeve rod 405, and the other end is against the first connecting section 4041, which facilitates the assembly of the spring 406, and the compression force of the spring 406 can be transmitted to the support component 403 through the first connecting section 4041.

[0074] Specifically in one embodiment, the outer diameter of the first connecting section 4041 is greater than the outer diameter of the second connecting section 4042 .

[0075] Specifically in one embodiment, the length of the first connecting segment 4041 is smaller than the length of the second connecting segment 4042 , so that the spring 406 is closer to the supporting component 403 .

[0076] In one embodiment, the cleaning device includes a body 2, the floor brush 1 is connected to the body 2 through a corner assembly 108, the corner assembly 108 is connected to the floor brush 1 through a bearing 111, the adapter includes a bearing 111, and the end of the sleeve rod 405 away from the connecting rod 404 is provided with an arc portion adapted to the outer surface of the bearing 111, and the elastic force of the spring 406 can keep the arc portion in contact with the bearing 111.

[0077] In this embodiment, the setting of the corner assembly 108 allows the angle between the body 2 and the floor brush 1 to be adjusted, which is convenient for users. The corner assembly 108 is connected to the floor brush 1 through a bearing 111. The adapter includes a bearing 111. The end of the sleeve rod 405 away from the connecting rod 404 is provided with an arc portion that adapts to the outer surface of the bearing 111. The elastic force of the spring 406 can keep the arc portion in contact with the bearing 111. The bearing 111 is used to locate the position of the sleeve rod 405 without adding additional parts. In addition, when the spring 406 is compressed, the bearing 111 acts on the spring 406 to tilt downward. The reaction force is then transmitted to the support component 403 through the connecting rod 404, thereby increasing the pressure applied by the support component 403 to the bottom shell 101.

[0078] In one embodiment, the cleaning device includes a controller 110 and an angle detection component. The angle detection component can detect the angle between the body 2 and the floor brush 1. The controller 110 is communicated with the angle detection component and the driving component, and can control the driving component to rotate to a corresponding angle according to the angle detected by the angle detection component.

[0079] In this embodiment, due to the different torsion angles of the body 2 relative to the floor brush 1, the pressure on the bottom shell 101 of the floor brush 1 is different. When the body 2 is upright, its positive pressure is the largest. By setting an angle detection component, the angle detection component can detect the angle between the body 2 and the floor brush 1. The controller 110 controls the driving component to rotate the corresponding angle according to the angle detected by the angle detection component, so that the pressure of the floor brush 1 on the ground can be kept constant.

[0080] It should be noted that the pressure of the floor brush 1 on the floor can be kept constant by obtaining the relationship between the angle between the body 2 and the floor brush 1 and the rotation angle of the driving component based on multiple tests.

[0081] In one embodiment, the bottom shell 101 is provided with a limiting structure, and the limiting structure is used to enable the supporting component 403 to rotate between a first position and a second position.

[0082] In this embodiment, a limiting structure is provided so that the support component 403 can only rotate between the first position and the second position, which makes it easier to control the rotation direction.

[0083] Specifically in one embodiment, the angle between the first position and the second position is 90°, that is, the rotation angle of the support rod is 90°, and the limiting structure restricts the support component 403 to rotate only between the first position and the second position.

[0084] In one embodiment, the cleaning device has a normal mode and a strong mode. In the normal mode, the support component 403 is in the first position. In the strong mode, the support component 403 is in the second position.

[0085] In this embodiment, in the strong mode, the overall pressure exerted by the floor brush 1 on the ground is relatively large, thereby increasing the friction between the roller brush 103 and the ground, which can effectively remove stubborn stains. If it is always in the strong mode, the support component 403 is always in the second position, and the floor brush 1 is in the supercharged state, the friction between the roller brush 103, the scraper 104 and the ground will increase in this state, resulting in accelerated actual wear. After the roller brush 103 is worn, it will cause many problems such as increased water stains and reduced cleaning effect. Replacing the roller brush 103 with a new one will increase the user's usage costs. The scraper 104 increases the friction on the ground for a long time. Although the scraper 104 is generally made of soft rubber material, the large pressure has a certain probability of scratching the ground and causing partial scratches. It will also cause the scraper 104 to age more severely, wear more severely, and the contact surface to be uneven. After the whole machine is running, it will cause stripes of water marks, affecting the user experience. Therefore, the normal mode is set. When the stubborn stains are removed, the driving component can be operated and switched to the normal mode to drive the support component 403 to the first position. At this time, the overall pressure of the floor brush 1 on the ground is relatively reduced, which can reduce the wear on the roller brush 103.

[0086] In addition, in the strong mode, the amount of water sprayed by the water pump 109 to the roller brush 103 is greater than that in the normal mode, and the suction force of the fan is greater than that in the normal mode, which can further clean stubborn stains.

[0087] In one embodiment, the cleaning device includes a handle 3 , which is provided with a button 301 , which can switch between a normal mode and a strong mode when pressed.

[0088] In this embodiment, the user can switch between the normal mode and the strong mode by operating the button 301, which is convenient for user operation.

[0089] In one embodiment, the floor brush 1 is provided with a dirt detection module, and the cleaning device includes a controller 110, which is communicated with the dirt detection module and the driving component. When the dirt detection module detects a preset degree of dirt, the driving component can control the driving component to drive the supporting component 403 to move to the second position.

[0090] In this embodiment, by providing a dirt detection module, the controller 110 can control the driving component to drive the supporting component 403 to move to the second position when the dirt detection module detects a preset degree of dirt, which is more intelligent.

[0091] Specifically, dirt can be divided into light, medium and heavy. When it is heavy dirt, it is often accompanied by stubborn stains. When the dirt detection module detects heavy dirt, it controls the driving component to drive the supporting component 403 to move to the second position.

[0092] In one embodiment, when the dirt detection module detects a preset degree of dirt, the controller 110 controls the driving component to drive the supporting component 403 to move to the second position, and drives the supporting component 403 to move to the first position after maintaining the second position for a preset period of time.

[0093] In this embodiment, when the dirt detection module detects a preset degree of dirt, the controller 110 controls the driving component to drive the support component 403 to move to the second position, and drives the support component 403 to move to the first position after maintaining the second position for a preset period of time. This can avoid the support component 403 being in the second position for a long time, causing wear of the roller brush 103.

[0094] Specifically in one embodiment, the preset time length is 3 seconds. Since in general, when a user uses a floor scrubber to mop the floor, a reciprocating motion can be performed in 1.5 seconds, it is more reasonable to set the preset time length to the time of two reciprocating motions.

[0095] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by this application.
