[0002] With the development of science and technology and the improvement of living standards, household cleaning equipment such as sweepers, floor scrubbers, mops, and sweeper-mop combos have become increasingly popular, reducing the burden of housework.

[0003] In the prior art, the cleaning equipment has a suction port and a first scraping condition. When the cleaning equipment pushes the surface to be cleaned forward, the first scraping condition pushes the dirt toward the side where the suction port is located, and the suction port absorbs the dirt on the surface to be cleaned.

In the case of sewage, it can also wipe away water stains on the surface to be cleaned, achieving a cleaning effect with zero water stain residue. Attached Figure Description

[0044] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0045] With the development of science and technology and the improvement of living standards, household cleaning equipment such as sweepers, floor scrubbers, mops, and sweeper-mop combos have become increasingly popular, reducing the burden of housework. In existing technologies, cleaning equipment has a suction port and a first scraping condition. When the cleaning equipment pushes forward to clean the surface, the first scraping condition pushes the dirt towards the side where the suction port is located, and the suction port absorbs the dirt from the surface. However, in the forward-pushing state of the cleaning equipment, the degree of contact between the first scraping condition and the surface to be cleaned in existing technologies is unstable, easily leading to incomplete absorption of dirt from the surface. For example, when the cleaning equipment is a sweeper, the dirt consists of solid materials such as dust, particles, debris, and hair; when the cleaning equipment is a floor scrubber, mop, or sweeper-mop combo, the dirt is in a liquid state (e.g., water) or a solid-liquid mixture (solid materials mixed with water).

[0046] However, existing cleaning equipment suffers from incomplete absorption of dirt from the surface to be cleaned. It should be noted that during the cleaning process, the cleaning equipment needs to move relative to the surface. As the equipment moves, the dirt on the surface also moves relative to the equipment, leading to incomplete absorption of dirt.

[0047] In view of this, this application provides a cleaning device and a cleaning system. In the initial state, the working part is pressed against the surface to be cleaned by the interference between the working part and the surface to be cleaned. When the cleaning device changes from the initial state to the forward-pushing state, the working part tilts backward under the action of the surface to be cleaned. In the forward-pushing state, the cleaning device scrapes away dirt from the surface to be cleaned by the working part with the first scraping condition, causing the dirt to move along with the forward-pushing cleaning device, so that the dirt is maintained near the suction port and can be absorbed by the suction port. At the same time, the working part is supported by the abutment between the first support structure and the working part, so that the backward-tilting working part is tightly pressed against the surface to be cleaned, increasing the tightness of the fit between the working part and the surface to be cleaned, preventing dirt from being missed, and solving the problem that the cleaning device is prone to incomplete absorption of dirt on the surface to be cleaned in the forward-pushing state. In addition, the cleaning device provided by this application can also wipe away water stains on the surface to be cleaned when the dirt is sewage, achieving a cleaning effect with zero water stain residue.

[0048] Reference Figures 1-11 In the description of this application, a coordinate system is established using three mutually perpendicular coordinate axes in space: the X-axis, Y-axis, and Z-axis. In the description of this application, "front" corresponds to the negative direction of the X-axis; "back" corresponds to the positive direction of the X-axis; "left" corresponds to the negative direction of the Y-axis; "right" corresponds to the positive direction of the Y-axis; "up" corresponds to the positive direction of the Z-axis; and "down" corresponds to the negative direction of the Z-axis.

[0049] Reference Figure 1 It should be noted that the cleaning equipment 1000 provided in this application can be a sweeper, floor scrubber, mop, sweeper-mop combo, or window cleaner. The cleaning equipment 1000 provided in this application can be handheld or self-propelled. It is understood that when the cleaning equipment 1000 is a sweeper, floor scrubber, mop, or sweeper-mop combo, the corresponding surface 10 to be cleaned is the ground; when the cleaning equipment 1000 is a window cleaner, the corresponding surface 10 to be cleaned is the glass surface.

[0050] Reference Figure 1 and Figure 2 The cleaning equipment 1000 includes: a floor brush device 100, cleaning components 200 and 300.

[0051] Reference Figure 1The floor brush device 100 includes a suction port 110 and is adapted to move along the surface 10 to be cleaned. It should be noted that the cleaning device 1000 performs cleaning operations on various locations of the surface 10 by moving the floor brush device 100 along the surface 10. During the cleaning operation, dirt is absorbed through the suction port 110. For example, the suction port 110 is connected to a negative pressure device to create a negative pressure at the suction port 110, thereby absorbing dirt. For example, in some embodiments, the cleaning device 1000 and the negative pressure device are designed separately, with the cleaning device 1000 and the corresponding negative pressure device connected via a flexible hose to create negative pressure at the suction port 110. In this separate design, the cleaning device 1000 can be equipped with a handle for easy handheld use by cleaning personnel. In some other embodiments (e.g., self-propelled sweepers, self-propelled mops, or self-propelled sweeper-mop combos), the cleaning device 1000 and the negative pressure device are integrated into a single unit. This integrated design facilitates the overall movement of the cleaning device 1000 and is suitable for self-propelled cleaning devices 1000. For example, when the cleaning device 1000 is self-propelled, drive wheels are provided on the floor brush device 100 to drive the floor brush device 100 to move on the surface 10 to be cleaned.

[0052] Reference Figure 1 and Figure 2 The cleaning component 200 is movably disposed at the suction port 110 to clean the surface 10 to be cleaned. It should be noted that "movably disposed at" here means that the cleaning component 200 has the ability to move. The cleaning component 200 can be flexibly configured according to the specific needs of the cleaning device 1000. For example, when the cleaning device 100 is a sweeper, the cleaning component 200 can be a roller brush with bristles, which rolls relative to the suction port 110 to clean the surface 10 to be cleaned. For example, when the cleaning device 100 is a mop, the cleaning component 200 can be a plush roller brush or a sponge roller brush, which rolls relative to the suction port 110 to clean the surface 10 to be cleaned. Furthermore, in some embodiments, the cleaning component 200 can also clean the surface 10 to be cleaned through vibration.

[0053] Reference Figure 1 and Figure 2The first scraping condition 300 is provided on the floor brush device 100 and located on one side of the cleaning component 200 in the front-to-back direction. The first scraping condition 300 includes: a working part 310 and a first support structure 320. The working part 310 is used to scrape away dirt on the surface 10 to be cleaned. It should be noted that the working part 310 extends in the left-to-right direction. For example, the portion of the working part 310 that contacts the surface 10 to be cleaned can have a certain degree of elasticity, so that when the working part 310 abuts against the surface 10 to be cleaned, the working part 310 can better conform to the ground, and this conformity is used to reduce the gap between the working part 310 and the ground. In specific implementation, the working part can be made of rubber, silicone, or some plastics that combine flexibility and elasticity.

[0054] Reference Figure 2 The first support structure 320 is disposed on the first scraping condition 300 and located on the side of the working part 310 facing away from the cleaning component 200. For example, the first support structure 320 may be a protrusion extending out of the first scraping condition 300 and integrally formed with the first scraping condition 300; the first support structure 320 may also be a block-shaped or bracket-shaped structure with a supporting function detachably connected to the first scraping condition 300. For example, the number of first support structures 320 may be one, and when the number of first support structures 320 is one, the first support structure 320 extends in the left-right direction; the number of first support structures 320 may also be multiple, with multiple first support structures 320 arranged sequentially at intervals in the left-right direction.

[0055] Reference Figures 1 to 3 The cleaning equipment 1000 has an initial state and a forward state.

[0056] Reference Figure 1 and Figure 2 In the initial state, the working part 310 is perpendicular to the surface 10 to be cleaned, and the working part 310 interferes with the surface 10 to be cleaned. It should be noted that the initial state refers to a virtual state, in which the surface 10 to be cleaned is regarded as a reference surface that does not exert a force on the working part 310. It can be understood that by setting the amount of interference between the working part 310 and the surface 10 to be cleaned, the cleaning equipment 1000 can ensure that the working part 310 can rest against the corresponding physical surface 10 to be cleaned during actual cleaning operations.

[0057] Reference Figure 3 In the forward-pushing state, the working part 310 tilts backward relative to the vertical direction and partially abuts against the first support structure 320. Under the support of the first support structure 320, the working part 310 scrapes away the dirt on the surface to be cleaned 10. Under this support, the fit between the working part 310 and the surface to be cleaned 10 is more stable, and the working part 310 can avoid leaving dirt behind.

[0058] Reference Figures 1 to 3 The cleaning equipment 1000 is adapted to move along the surface 10 to be cleaned via a floor brush device 100 to perform cleaning operations on the surface 10. The floor brush device 100 absorbs dirt from the surface 10 through a suction port 110. In its initial state, the cleaning equipment 1000's working part 310 is pressed against the surface 10 by the interference between the working part 310 and the surface 10. When the cleaning equipment 1000 changes from the initial state to the forward-pushing state, the working part 310 is pulled backward and tilted by the surface 10 to increase the contact area between the working part 310 and the surface 10, thereby enhancing the scraping ability of the working part 310 on the dirt. In the forward-pushing state, the cleaning device 1000 scrapes away dirt from the surface 10 to be cleaned by the working part 310 of the first scraping condition 300, so that the dirt moves along with the forward-pushing cleaning device 1000 and is kept near the suction port 110 so that the dirt can be absorbed by the suction port 110. At the same time, the working part 310 is supported by the abutment between the first support structure 320 and the working part 310, so that the backward-inclined working part 310 is tightly pressed against the surface 10 to be cleaned, stabilizing the degree of contact between the working part 310 and the surface 10 to be cleaned, preventing dirt from being missed, and also solving the problem that the cleaning device 1000 is prone to incomplete absorption of dirt on the surface 10 to be cleaned in the forward-pushing state.

[0059] Understandably, the cleaning equipment 1000 provided in this application can also wipe away water stains on the surface 10 to be cleaned, even when the dirt is sewage, achieving a cleaning effect with zero water stain residue.

[0060] Reference Figure 1 and Figure 2 In some embodiments, the first scraping condition 300 further includes a fixing part 330, which is fixedly connected to the floor brush device 100. For example, the fixing part 330 can be glued to the floor brush device 100, the fixing part 330 can be fixed to the floor brush device 100 by fasteners, or the fixing part 330 can be fixed by some structure that can form a snap connection with the floor brush device 100.

[0061] Reference Figure 2 , Figure 5 , Figure 6 and Figure 7For example, in a specific implementation, a protrusion 330a can be provided on the fixing part 330. The protrusion 330a is located near the top of the fixing part 330 and protrudes rearward. A corresponding protrusion opening is provided on the floor brush device 100 or a component fixedly connected to the floor brush device 100. The fixing part 330 is positioned and limited on the floor brush device 100 by the cooperation of the protrusion 330a and the corresponding protrusion opening. Alternatively, a socket 330b can be provided on the fixing part 330. The socket 330b is located below the protrusion 330a and is located adjacent to the protrusion 330a. The socket 330b extends in the front-to-back direction and its opening faces rearward. A plug that mates with the socket 330b is provided at a corresponding position on the floor brush device 100 or a component fixedly connected to the floor brush device 100, so that positioning is achieved by the cooperation of the socket 330b and the corresponding plug. A step surface 330c can also be provided on the rear side of the fixing part 330, and a buckle head 330d is provided on the step surface 330c facing upward. A buckle opening that cooperates with the buckle head 330d is provided at the corresponding position on the floor brush device 100 or the component fixedly connected to the floor brush device 100.

[0062] Two pressure strips 331 can also be provided on the fixing part 330. The bottom of the floor brush device 100 is provided with a pressure plate 400. The pressure plate 400 has multiple screw through holes 410. The pressure plate 400 is fastened to the bottom of the floor brush device 100 by screws that pass through the screw through holes 410. The two pressure strips 331 are pressed and fixed to the bottom of the floor brush device 100 by the pressure plate 400, so as to further fix the fixing part 330.

[0063] Furthermore, the protruding opening that mates with the protruding strip 330a, the plug that mates with the socket 330b, and the snap-fit ​​opening that mates with the snap-fit ​​head 330d can all be provided on the pressure plate 400. It is understood that the pressure plate 400 can have a portion that extends in the vertical direction.

[0064] Furthermore, an insert 331a can be provided on the pressure strip 331. The insert 331a extends downward from the pressure strip 331, and a stop 331b is connected to the lower end of the insert 331a. The pressure plate 400 has a hole that mates with the insert 331a. The insert 331a is inserted into the hole, and the stop 331b is located at the lower end of the hole to prevent the insert 331a from falling out of the hole. It can be understood that the cooperation of the insert 331a, the stop 331b, and the pressure plate 400 can further enhance the firmness of the connection between the fixing part 330 and the floor brush device 100.

[0065] Reference Figure 2 , Figure 3 and Figure 7A first support structure 320 is provided on the fixed portion 330. The fixed portion 330 provides certain support for the first support structure 320. The working portion 310 is connected to the fixed portion 330. For example, the first support structure 320 can be a rigid member or an elastic member. When the first support structure 320 is a rigid member, the entire first support structure 320 is fixed relative to the fixed portion 330. When the first support structure 320 is an elastic member, the first support structure 320 can undergo elastic deformation; when the first support structure 320 undergoes elastic deformation, at least part of the first support structure 320 can move relative to the fixed portion 330. It can be understood that when the first support structure 320 is an elastic member, the first support structure 320 can provide elastic support for the rearward tilting working portion 310, preventing damage to the working portion 310.

[0066] Reference Figure 2 and Figure 3 In some embodiments, the rear sidewall of the working part 310 is provided with an abutment structure 310a. For example, in a cross-section perpendicular to the left and right directions, the cross-sectional shape of the abutment structure 310a can be approximately trapezoidal, semi-circular, or rectangular. Furthermore, rounded corners can be provided on the portion of the abutment structure 310a used to abut against the working part 310.

[0067] Reference Figure 3 In the forward-pushing state, the abutting structure 310a abuts against the first support structure 320. It is understandable that the abutting structure 310a abuts against the first support structure 320 to ensure contact between the working part 310 and the first support structure 320. By providing the abutting structure 310a, the thickness (approximately in the front-back direction) of the portion of the working part 310 that needs to abut against the first support structure 320 is increased, facilitating timely contact between the working part 310 and the first support structure 320. Simultaneously, it helps maintain a relatively small thickness at the lower end of the working part 310, allowing for better adhesion between the lower end of the working part 310 and the surface 10 to be cleaned.

[0068] Reference Figure 2In some embodiments, in the initial state, the abutment structure 310a extends in the front-to-back direction, and at least a portion of the first support structure 320 extends backward at an angle relative to the vertical direction. This design allows the first support structure 320 to initially face the abutment structure 310a, facilitating timely contact between the abutment structure 310a and the first support structure 320 as the working part 310 transitions from a vertical to a backward-tilting position. The abutment structure 310a is spaced apart from the first support structure 320 to provide space for the working part 310 to tilt backward. For example, the portion of the working part 310 above the abutment structure 310a and below the first support structure 320 is elastic. After the working part 310 tilts backward, this elastic force allows the lower end of the working part 310 to press firmly against the surface 10 to be cleaned. In addition, the sealing effect between the lower end of the working section 310 and the surface 10 to be cleaned can be improved by increasing the weight of the lower end of the working section 310. Specifically, a counterweight can be wrapped around the end portion of the working section 310 to increase its weight.

[0069] Reference Figure 4 In some embodiments, in the forward-pushing state, the angle between the working part 310 and the vertical direction is 30° to 40°. It is understood that in the forward-pushing state, the force exerted by the working part 310 on the surface to be cleaned 10 can be decomposed into a downward pressure on the surface to be cleaned 10 and a forward thrust (for pushing away dirt). This range of angles between the working part 310 and the vertical direction helps maintain the pressure between the working part 310 and the surface to be cleaned 10, ensuring the degree of contact between the lower end of the working part 310 and the surface to be cleaned 10, and also maintaining the forward thrust of the working part 310 on the dirt.

[0070] Reference Figure 3 and Figure 5 The first support structure 320 is formed as a support strip extending along the length direction (i.e., the left-right direction) of the first scraping condition 300. Understandably, in the forward-pushing state, this support strip can provide continuous support to the working part 310 in the left-right direction, ensuring that there is no gap between the bottom of the working part 310 and the surface 10 to be cleaned.

[0071] Reference Figure 2 As illustrated, in the initial state, the interference amount between the working part 310 and the surface 10 to be cleaned (i.e., the vertical dimension of the portion of the working part 310 below the surface 10 to be cleaned) is 0.5mm-0.8mm, for example, 0.5mm, 0.6mm, 0.7mm, or 0.8mm. In the initial state, this interference amount ensures that the lower end of the working part 310 makes sufficient contact with the ground without excessively supporting the floor brush device 100 on the surface 10 to be cleaned. Figure 2This is only to illustrate the amount of interference between the working part 310 and the surface 10 to be cleaned, and does not mean that the working part 310 extends into the surface 10 to be cleaned.

[0072] Reference Figure 2 and Figure 4 The first scraping condition 300 also includes a second support structure 340. The second support structure 340 is located at the bottom end of the rear side wall of the working part 310. The cleaning device 1000 also includes a pulled-back state. In the initial state, the second support structure 340 is separated from the surface to be cleaned 10. It should be noted that this separation prevents the second support structure 340 from separating the lower end of the working part 310 from the surface to be cleaned 10 in the initial state, ensuring that the lower end of the working part 310 is fully in contact with the surface to be cleaned 10 in the initial state.

[0073] Reference Figure 4 In the pulled-back state, the working part 310 tilts forward relative to the vertical direction, and the second support structure 340 abuts against the surface 10 to be cleaned, thus separating the working part 310 from the surface 10. It should be noted that in the pulled-back state, the suction port 110 is located in front of the working part 310. In this state, dirt on the surface 10 to be cleaned located in front of the working part 310 enters the front of the working part 310 through the gap formed after the working part 310 is separated from the surface 10, allowing the dirt to be absorbed by the suction port 110, thus enabling the cleaning equipment to have a certain ability to clean dirt in the pulled-back state. For example, the second support structure 340 can be a cuboid block, a hemispherical block, or a semi-cylindrical block. When the second support structure 340 is a cuboid block, transition arcs can be provided at the corners of the cuboid. The second support structure 340 can also be an elastic element.

[0074] Reference Figure 2 , Figure 4 and Figure 7 In some embodiments, the second support structure 340 is formed as a support block, and there are multiple second support structures 340 spaced apart along the length direction of the first scraping condition 300. A water passage gap is defined between two adjacent support blocks. It is understood that the water passage gap facilitates the smooth passage of dirt.

[0075] Reference Figure 1 , Figure 4 , Figure 6 , Figure 9 , Figure 10 and Figure 11 In some embodiments, the cleaning device 1000 further includes a second scraping condition 500. The second scraping condition 500 is movably disposed on the floor brush device 100. It should be noted that "movably disposed" here means having the ability to move. The second scraping condition 500 abuts against or releases from the surface to be cleaned 10 by moving relative to the floor brush device 100.

[0076] For example, the movement of the second scraping condition 500 relative to the floor brush device 100 can be relative oscillation, relative movement, or a combination of relative oscillation and relative movement; it can also be relative oscillation and relative movement performed in sequence.

[0077] The second scraping condition 500 is located on the side of the cleaning component 200 opposite to the first scraping condition 300. In the pulled-back state, the second scraping condition 500 abuts against the surface 10 to be cleaned, thereby scraping away water stains on the surface 10. For example, the material of the part of the second scraping condition 500 that abuts against the surface 10 to be cleaned can be plastic, silicone, or rubber. It should be noted that in the pulled-back state, on the one hand, the second scraping condition 500 abutting against the surface 10 to be cleaned forms a seal on the side of the cleaning component 200 opposite to the first scraping condition 300, which helps maintain the vacuum level to maintain the suction capacity of the suction port 110; on the other hand, the second scraping condition 500 abutting against the surface 10 to be cleaned can scrape away water stains that have passed through the water passage and remained on the surface to be cleaned, ensuring a cleaning effect.

[0078] Reference Figure 9 , Figure 10 and Figure 11 In addition, some embodiments of the cleaning device also include a drive mechanism 600 and a resilient reset member 700. The drive mechanism 600 is disposed on the floor brush device 100 and is in transmission cooperation with the second scraping condition 500. The drive mechanism 600 drives the second scraping condition 500 to move toward the surface 10 to be cleaned, so that the second scraping condition 500 abuts against the surface 10 to be cleaned. For example, the drive mechanism 600 may be a servo electric cylinder, which slidably connects the second scraping condition 500 to the floor brush device 100 via a guide member, and drives the movement of the second scraping condition 500 by means of the servo electric cylinder. For example, the drive mechanism 600 can also be a mechanism based on the gear and rack transmission principle. Specifically, the second scraping condition 500 is slidably connected to the floor brush device 100 through a guide member. A rack is provided on the second scraping condition 500 and extends along the sliding direction of the second scraping condition 500. The gear meshes with the rack. A motor drives the gear to rotate, so that the rotating gear drives the rack to move, so that the moving rack drives the second scraping condition 500 to move.

[0079] A resilient reset member 700 is disposed on the floor brush device 100. The resilient reset member 700 is in a driving engagement with the second scraping condition 500. The resilient reset member 700 is used to drive the second scraping condition 500 to move away from the surface to be cleaned 10. The resilient reset member 700 can drive the second scraping condition 500 away from the surface to be cleaned 10. When the resilient reset member 700 drives the second scraping condition 500 to move away from the surface to be cleaned 10, the drive mechanism 600 disengages from the second scraping condition 500. It should be noted that the disengagement here means that the drive mechanism 600 no longer drives the second scraping condition 500 towards the surface to be cleaned 10, and does not obstruct the second scraping condition 500 from moving away from the surface to be cleaned. For example, the resilient reset member 700 can be a tension spring, one end of which is fixed to the floor brush device 100, and the other end of which is fixed to the second scraping condition 500, so that the second scraping condition 500 is driven away from the surface to be cleaned 10 by the elastic force of the tension spring after it is stretched. The second scraping condition 500 may have a frame 510 for connecting the tension spring and the drive mechanism 600, and the frame 510 is for sliding connection with the floor brush device 100.

[0080] For example, when the drive mechanism 600 is a servo electric cylinder, the telescopic rod of the servo electric cylinder abuts against the frame 510. The telescopic rod of the servo electric cylinder drives the frame 510 to move so as to drive the second scraping condition 500 to move toward the surface to be cleaned 10. When the elastic reset member 700 drives the second scraping condition 500 to move away from the surface to be cleaned 10, the telescopic rod of the servo electric cylinder retracts to disengage from the second scraping condition.

[0081] For example, when the drive mechanism is based on the gear and rack transmission principle, the motor used to drive the gear has no self-locking configuration, meaning that the motor can rotate in the opposite direction under external force after power failure. When the elastic reset member 700 drives the second scraping condition 500 to move away from the surface to be cleaned 10, the motor is de-energized, so as to disengage the drive mechanism 600 from the second scraping condition 500 by de-energizing the motor; the second scraping condition 500 drives the rack to move in the opposite direction, the rack drives the gear to reverse, and the rack drives the motor to rotate in the opposite direction.

[0082] Reference Figures 9 to 10In some embodiments, the drive mechanism 600 includes a power member 610 and a transmission member 620. The power member 610 is disposed on the floor brush device 100. Exemplarily, the power member 610 may be a motor, and the floor brush device 100 has a connecting seat 120 for fixing the motor's base. The transmission member 620 is driveably connected to the power member 610, and the power member 610 drives the transmission member 620 to rotate to engage with the second scraping condition 500. The power member 610 and the transmission member 620 provide power for the second scraping condition 500 to contact the ground. When the power member 610 is a motor, the transmission member 620 may be a gear and rack; the transmission member 620 may also be a linkage; the transmission member 620 may also be a cam.

[0083] In the embodiments of this application, the transmission component 620 is described as a cam. The cam is connected to the motor. The frame 510 of the second scraping condition 500 is pressed against the cam by the elastic reset component 700. The rotation of the cam causes the drive mechanism 600 to form or disengage from the second scraping condition 500. When the drive mechanism 600 forms an engagement with the second scraping condition 500, the drive mechanism 600 drives the second scraping condition 500 to move toward the surface 10 to be cleaned.

[0084] Reference Figure 2 In a specific implementation, the first scraping condition 300 is an elastic element. Specifically, the working part 310 can be elastic, the abutment structure 310a can be elastic, and the first support structure 320 can be elastic. For example, the first scraping condition 300 can be made of elastic silicone, elastic rubber, or elastic plastic. Alternatively, an elastic support element made of elastic metal can be encased inside the first scraping condition 300 to achieve the corresponding elasticity.

[0085] Reference Figure 8 This application also provides a cleaning system including a cleaning base station 2000 and the aforementioned cleaning device 1000. The cleaning base station 2000 is configured to clean the cleaning component 200 of the cleaning device 1000. The specific functional structure of the cleaning base station 2000 can be flexibly selected according to the corresponding cleaning device 1000. For example, when the cleaning device 1000 is a sweeper, the cleaning base station 2000 can clean the sweeper by removing foreign objects entangled on the cleaning component 200; when the cleaning device 1000 is a mop, the cleaning base station 2000 can clean and disinfect the sweeper by washing and disinfecting the cleaning component 200. In addition, in some embodiments, the cleaning base station 2000 is also used to store and / or charge the corresponding cleaning device 1000.
