Description

Cleaning device

[0001] The present application claims priority to the Chinese patent application No. 2024215270820 filed on July 1, 2024, and entitled "A cleaning device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of cleaning equipment, and more particularly, to a cleaning device. BACKGROUND

[0003] A scrubber is a cleaning device suitable for household use, mainly used for cleaning and washing the surface of the household floor. The scrubber usually has the functions of water spraying and water absorption. The scrubber can automatically spray water and wash the floor, and then absorb the sewage and residual dirt into the sewage tank of the machine. The scrubber is convenient to use and can provide thorough cleaning effect.

[0004] After the scrubber cleans the floor, there are many water stains left on the floor, especially when the user pulls the scrubber backward to clean the floor. The scrubber on the market currently sets a lifting type scraping strip device at the front end of the cleaning device. The lifting type scraping strip device includes a power member and a scraping strip assembly. When the scrubber retreats, the power member drives the scraping strip assembly to make a downward movement, so that the scraping strip assembly is attached to the floor to scrape off the residual water and residual debris on the floor. However, since the power member and the scraping strip assembly are arranged at the front end of the cleaning device, the volume of the front part of the cleaning device is large, which is not conducive to the cleaning device to enter the low area under the bed, under the sofa, under the table and chair, etc. for cleaning, and has an adverse effect on the product appearance of the cleaning device.

[0005] Therefore, it is urgent to solve the above technical problems of the scrubber on the market.

[0006] CONTENT OF THE UTILITY MODEL

[0007] The present application aims to provide a cleaning device that can ensure the cleaning performance of the cleaning device and reduce the influence of the driving assembly of the cleaning device on the product appearance.

[0008] The application provides a cleaning device, comprising: a device body capable of moving on a to-be-cleaned surface in a preset moving direction; a cover body arranged at the front end of the device body in the preset moving direction; a cleaning piece close to the to-be-cleaned surface relative to at least part of the cover body; the cleaning piece has a central axis and a central section, the central axis is located on the central section, and the central section is perpendicular to the preset moving direction; a scraping strip is arranged on the cover body and located at the front side of the cleaning piece in the preset moving direction; a driving assembly comprises a power piece and a driving piece, at least part of the power piece is located at the rear side of the central section in the preset moving direction, and the driving piece is arranged on the cover body; the power piece drives the driving piece to move around the central axis, so that the driving piece drives the scraping strip to move in a direction intersecting the to-be-cleaned surface.

[0009] In some embodiments, the power piece is located at the rear side of the cleaning piece in the preset moving direction.

[0010] In this way, the power piece is arranged at the rear in the cleaning device, which can reduce the influence of the power piece on the volume of the front part of the cleaning device, and is conducive to ensuring the cleaning performance of the cleaning device, such as facilitating the cleaning device to enter low areas such as under a bed, under a sofa, under a table and chair, etc. In addition, the power piece is arranged at the rear in the cleaning device in this embodiment, and the power piece is not arranged at the front of the cleaning device, so that the influence of the driving assembly on the appearance of the cleaning device product can be reduced.

[0011] In addition, during the movement of the cleaning device in the preset moving direction, the cleaning piece can brush the to-be-cleaned surface in the preset moving direction. During the forward pushing of the cleaning device, the scraping strip is raised, which not only prevents the scraping strip from hindering the dirt on the to-be-cleaned surface in front from being sucked away, but also prevents the scraping strip from being deflected towards the direction close to the cleaning piece under the action of the backward friction force, thereby avoiding the deflected and deformed scraping strip from blocking the dirt suction gap between the cleaning piece and the cover body, and also avoiding the deflected and deformed scraping strip from being rolled into the dirt suction gap between the cleaning piece and the cover body. During the backward pulling of the cleaning device, the scraping strip moves towards the to-be-cleaned surface and adheres to the to-be-cleaned surface. During the backward pulling of the cleaning device, the scraping strip scrapes the dirt on the to-be-cleaned surface, thereby facilitating the reduction of the residual dirt on the to-be-cleaned surface and improving the cleaning effect of the cleaning device; at the same time, although the scraping strip is in continuous contact with the to-be-cleaned surface during the backward pulling of the cleaning device, the scraping strip will be slightly deflected away from the cleaning piece under the action of the forward friction force, thereby avoiding the deflected scraping strip from blocking the dirt suction gap between the cleaning piece and the cover body, and also equivalent to that the device body pulls the deflected scraping strip to move backward together, so that the user can save energy when performing the backward pulling action.

[0012] In addition, the existing front wiper strip structure is usually swing type or rotary type. During cleaning, since the wiper strip needs a certain angle to swing or rotate, when cleaning the dirt in the corner in front, a triangular dirt area is still formed among the wiper strip, the wall surface and the ground. The wiper strip in the technical solution is up-down movement type. Compared with the swing type or rotary type, when encountering the "edge dirt" in front of the device main body, the wiper strip can directly adhere to the wall and descend for cleaning, so that the cleaning is more clean and complete.

[0013] In some embodiments, the power member is arranged in the device main body.

[0014] In the above manner, the power member is arranged at the rear of the cleaning device, which can reduce the influence of the power member on the volume of the front part of the cleaning device, and is beneficial to ensure the cleaning performance of the cleaning device, for example, is beneficial to the cleaning device to enter the low area under the bed, under the sofa, under the table and chair, and the like. In addition, the power member is arranged at the rear of the cleaning device in the embodiment, and the power member is not arranged at the front of the cleaning device, so that the influence of the driving assembly on the appearance of the cleaning device product can be reduced.

[0015] In some embodiments, the driving assembly further comprises: an elastic driving member arranged in the cover body and in transmission cooperation with the wiper strip; one of the driving member and the elastic driving member is configured to drive the wiper strip to move towards the surface to be cleaned, and the other is configured to drive the wiper strip to move away from the surface to be cleaned; and the power member is configured to stop outputting driving force to the wiper strip when the elastic driving member drives the wiper strip.

[0016] In the above manner, when the elastic driving member drives the wiper strip to move, the power member does not output driving force to the wiper strip, which can reduce the working burden of the power member, thereby prolonging the service life of the power member. The power member can be a rudder, a motor or the like. The power member works in response to a corresponding control signal. Since there is a certain delay in the transmission of the signal, and the driving transmission mechanism of the power member also has a certain hysteresis, in the embodiment, when the elastic driving member drives the wiper strip to move, the power member does not output driving force to the wiper strip, and the elastic driving member can immediately drive the wiper strip to move, that is, the driving mode of the elastic driving member to drive the wiper strip has a faster response speed, which is beneficial to improve the response speed of the wiper strip action. In addition, by reasonably selecting the elastic coefficient of the elastic driving member, the elastic driving member can provide appropriate driving force to the wiper strip, which further enables the wiper strip to quickly respond to the driving force provided by the elastic driving member to move, and further improves the response speed of the wiper strip action.

[0085] Please refer to FIGS. 5 to 8 together. FIG. 5 is a structural schematic view of a region of the cleaning device B shown in FIG. 3, FIG. 6 is a structural schematic view of a region of the cleaning device C shown in FIG. 4, FIG. 7 is a structural schematic view of an embodiment of the cover and the scraping strip, and FIG. 8 is an exploded structural schematic view of the cover and the scraping strip shown in FIG. 7.

[0086] In some embodiments, the floor brush comprises the device main body 20 capable of moving on the cleaning surface 10a in the preset moving direction X. For example, the device main body 20 can be provided with a driving wheel, a track wheel, or the like, so that the device main body 20 is capable of moving on the cleaning surface 10a. The cleaning member 40 is arranged on the device main body 20. The floor brush further comprises the cover 30 arranged on the front end of the device main body 20 in the preset moving direction X, and the cleaning member 40 is close to the cleaning surface 10a relative to at least part of the cover 30. The floor brush further comprises the scraping strip 50 arranged on the cover 30, and the scraping strip 50 is located on the front side of the cleaning member 40 in the preset moving direction X. The scraping strip 50 is used to scrape off dirt on the cleaning surface 10a. The floor brush further comprises the driving assembly 60 used to drive the scraping strip 50 to move in a preset moving direction Z. The preset moving direction Z intersects with the cleaning surface 10a.

[0087] By the above manner, the driving assembly 60 of the cleaning device 10 is used to drive the scraping strip 50 to move along the preset movement direction Z to scrape the dirt on the to-be-cleaned surface 10a by the scraping strip 50, so that the dirt remaining on the to-be-cleaned surface 10a can be reduced. Especially, the scraping strip 50 is located at the front side of the cleaning piece 40, so that when the user pulls back the cleaning device 10 to clean, the scraping strip 50 can scrape the dirt on the to-be-cleaned surface 10a, and the dirt remaining on the to-be-cleaned surface 10a when the user pulls back the cleaning device 10 to clean can be reduced.

[0088] It should be noted that the movement of the cleaning device 10 along the preset movement direction X includes forward movement and backward movement of the cleaning device 10 along the preset movement direction X. The forward movement of the cleaning device 10 along the preset movement direction X means that the cleaning device 10 moves towards the front side thereof in the preset movement direction X, and the backward movement of the cleaning device 10 along the preset movement direction X means that the cleaning device 10 moves towards the rear side thereof in the preset movement direction X. The cleaning piece 40 is arranged close to the front side of the cleaning device 10 in the preset movement direction X.

[0089] The preset movement direction Z is substantially perpendicular to the to-be-cleaned surface 10a, specifically, the included angle between the preset movement direction Z and the normal direction of the to-be-cleaned surface 10a is θ, which satisfies: 0°≤θ≤10°, for example, 0°, 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, etc.

[0090] In some embodiments, in order to solve the problem that the dirt remaining on the to-be-cleaned surface 10a is serious when the user pulls back the cleaning device 10 to clean, when the user pulls back the cleaning device 10, that is, when the user pulls the cleaning device 10 to move backward along the preset movement direction X, the driving assembly 60 drives the scraping strip 50 to move towards the to-be-cleaned surface 10a, so that the scraping strip 50 moves to contact the to-be-cleaned surface 10a, so that the scraping strip 50 can scrape the dirt on the to-be-cleaned surface 10a with the action of the user pulling back the cleaning device 10, and the dirt remaining on the to-be-cleaned surface 10a can be reduced; when the user pushes the cleaning device 10, that is, when the user pushes the cleaning device 10 to move forward along the preset movement direction X, the driving assembly 60 drives the scraping strip 50 to move away from the to-be-cleaned surface 10a, so that the scraping strip 50 moves to have a gap with the to-be-cleaned surface 10a, so that the scraping strip 50 can avoid blocking the dirt in front of the cleaning device 10, and the cleaning device 10 can efficiently clean the dirt in front. It should be noted that the lower end of the cleaning device 10 is provided with a sensor or a movement direction sensing assembly for sensing the forward and backward movement directions of the cleaning device 10.

[0091] For the cleaning scene of the edge area such as the wall edge and the edge of furniture, taking the wall edge as an example, the cleaning element 40 in the form of a roller brush has a whole in the shape of a cylinder, which causes the cleaning element 40 to form a triangular dead angle area with the right-angled wall edge after the cleaning element 40 is close to the wall. In view of this, in the process of the user pushing the cleaning device 10 to be close to the wall, the driving assembly 60 keeps the state that there is a gap between the scraping strip 50 and the to-be-cleaned surface 10a; after the cleaning device 10 is close to the wall, the user pulls the cleaning device 10 backward, at this time, the driving assembly 60 drives the scraping strip 50 to move towards the to-be-cleaned surface 10a, the scraping strip 50 can extend into the triangular dead angle area, and the scraping strip 50 scrapes the dirt on the wall edge, greatly improving the cleaning effect of the edge area.

[0092] In addition, during the movement of the cleaning device along the preset advancing direction, the cleaning element can clean the to-be-cleaned surface along the preset advancing direction. During the pushing of the cleaning device, the scraping strip is raised, which not only prevents the scraping strip from hindering the dirt on the to-be-cleaned surface in front from being sucked away, but also prevents the scraping strip from being deflected towards the direction close to the cleaning element under the action of the backward friction force, thereby avoiding the deflected and deformed scraping strip from blocking the dirt suction gap between the cleaning element and the cover body, and also avoiding the deflected and deformed scraping strip from being wound into the dirt suction gap between the cleaning element and the cover body. When the cleaning device is pulled backward, the scraping strip moves towards and adheres to the to-be-cleaned surface. During the pulling of the cleaning device, the scraping strip scrapes the dirt on the to-be-cleaned surface, thereby facilitating the reduction of the dirt remaining on the to-be-cleaned surface and improving the cleaning effect of the cleaning device; at the same time, although the scraping strip is in continuous contact with the to-be-cleaned surface during the pulling of the cleaning device, the scraping strip will be slightly deflected away from the cleaning element under the action of the forward friction force, thereby avoiding the deflected scraping strip from blocking the dirt suction gap between the cleaning element and the cover body, and also equivalent to the device body pulling the deflected scraping strip to move backward together, which is more labor-saving for the user when performing the pulling action.

[0093] In addition, the existing front scraping strip structure is usually in the form of swinging or rotating. During the cleaning process, since the scraping strip needs to swing or rotate by a certain angle, a triangular dirt area will still be formed between the scraping strip, the wall surface and the ground when cleaning the dirt at the right-angled corner in front. The scraping strip in the technical solution is in the form of up-and-down movement, and compared with the swinging or rotating scraping strip, the scraping strip can directly adhere to the wall and descend to clean when encountering the "edge dirt" in front of the device body, and the cleaning is more clean and thorough.

[0094] In some embodiments, as shown in FIG. 3, the cleaning element 40 has a central axis O and a central section a. The cleaning element 40 extends along the central axis O. The central axis O of the cleaning element 40 is the section of the cleaning element 40, the central axis O is located on the central section a, and the central section a is perpendicular to the preset advancing direction X.

[0095] Please refer to FIG. 9 and FIG. 10. The driving assembly 60 comprises a power member 61 and a transmission mechanism 62. At least part of the power member 61 is located at the rear side of the central section a in the preset advancing direction X, and the transmission mechanism 62 is arranged on the cover 30. The power member 61 is in transmission cooperation with the scraping strip 50 through the transmission mechanism 62, so as to drive the scraping strip 50 to move in the preset movement direction Z.

[0096] In the above manner, at least part of the power member 61 is located at the rear side of the central section a of the cleaning member 40, i.e. the power member 61 is arranged rearward in the cleaning device 10, so as to reduce the influence of the power member 61 on the volume of the front part of the cleaning device 10, and facilitate to ensure the cleaning performance of the cleaning device 10, such as facilitating the cleaning device 10 to enter the low area below the bed, below the sofa, below the table and chair, etc. for cleaning. In addition, the power member 61 is arranged rearward in the cleaning device 10 in the embodiment, and the power member 61 is not arranged at the front part of the cleaning device 10, so as to reduce the influence of the driving assembly 60 on the product appearance of the cleaning device 10.

[0097] If the power member 61 is arranged at the front part of the cleaning device 10, which is close to the front side of the cleaning member 40 in the preset advancing direction X of the cleaning device 10, the power member 61 will cause the volume of the front part of the cleaning device 10 to be large, which is not conducive to the cleaning device 10 to enter the low area below the bed, below the sofa, below the table and chair, etc. for cleaning. In addition, the power member 61 will also cause the local position of the front part of the cleaning device 10 to protrude outward, which will adversely affect the product appearance of the cleaning device 10.

[0098] In some embodiments, the power member 61 is located at the rear side of the cleaning member 40 in the preset advancing direction X, i.e. the orthogonal projection of the power member 61 on the to-be-cleaned surface 10a does not overlap with the orthogonal projection of the cleaning member 40 on the to-be-cleaned surface 10a. Optionally, the power member 61 can be arranged on the device main body 20, as shown in FIG. 3. Of course, the power member 61 can also be arranged on the cover 30, etc., which is not limited herein.

[0099] Of course, in other embodiments of the present application, part of the orthogonal projection of the power member 61 on the to-be-cleaned surface 10a can overlap with the orthogonal projection of the cleaning member 40 on the to-be-cleaned surface 10a, and the remaining part of the power member 61 is located at the rear side of the cleaning member 40; or the orthogonal projection of the power member 61 on the to-be-cleaned surface 10a is in the orthogonal projection of the cleaning member 40 on the to-be-cleaned surface 10a, which is not limited herein.

[0100] In some embodiments, the driving assembly 60 further comprises an elastic driving member 63. The elastic driving member 63 is arranged on the cover 30, and the elastic driving member 63 is in transmission cooperation with the scraping strip 50. One of the transmission mechanism 62 and the elastic driving member 63 is configured to drive the scraping strip 50 to move towards the surface to be cleaned 10a, and the other is configured to drive the scraping strip 50 to move away from the surface to be cleaned 10a. When the user pulls the cleaning device 10 backward, the scraping strip 50 is driven to move towards the surface to be cleaned 10a, so that the scraping strip 50 moves to be in contact with the surface to be cleaned 10a, and thus the scraping strip 50 can scrape off dirt on the surface to be cleaned 10a with the action of the user pulling the cleaning device 10 backward, and the residual dirt on the surface to be cleaned 10a can be reduced, as shown in FIGS. 3 and 5; when the user pushes the cleaning device 10 forward, the scraping strip 50 is driven to move away from the surface to be cleaned 10a, so that the scraping strip 50 moves to be spaced apart from the surface to be cleaned 10a, and thus the scraping strip 50 can avoid blocking dirt in front of the cleaning device 10, so that the cleaning device 10 can efficiently clean the dirt in front, as shown in FIGS. 4 and 6.

[0101] The power member 61 is configured to stop outputting driving force to the scraping strip 50 when the elastic driving member 63 drives the scraping strip 50. When the elastic driving member 63 drives the scraping strip 50 to move, the power member 61 does not output driving force to the scraping strip 50, which can reduce the working burden of the power member 61, thereby prolonging the service life of the power member 61. The power member 61 can be a rudder, a motor or other power element. The power member 61 works in response to a corresponding control signal. Since there is a certain delay in the transmission of the signal, and there is also a certain hysteresis in the driving of the transmission mechanism 62 by the power member 61, in the present embodiment, when the elastic driving member 63 drives the scraping strip 50 to move, the power member 61 does not output driving force to the scraping strip 50, and the elastic driving member 63 can immediately drive the scraping strip 50 to move, that is, the way in which the elastic driving member 63 drives the scraping strip 50 to move has a faster response speed, which is beneficial to improving the response speed of the action of the scraping strip 50. Moreover, in the present embodiment, the elastic coefficient of the elastic driving member 63 is reasonably selected, so that the elastic driving member 63 can provide appropriate driving force to the scraping strip 50, and further enable the scraping strip 50 to quickly respond to the driving force provided by the elastic driving member 63 to move, which is further beneficial to improving the response speed of the action of the scraping strip 50.

[0102] Of course, in other embodiments of the present application, the driving assembly 60 is not limited to driving the scraping strip 50 to move towards the surface to be cleaned 10a and away from the surface to be cleaned 10a by the cooperation of the elastic driving member 63 and the transmission mechanism 62, for example, the driving assembly 60 can also drive the scraping strip 50 to move towards the surface to be cleaned 10a and away from the surface to be cleaned 10a by the cooperation of a connecting rod structure, a gear structure or the like and the transmission mechanism 62, which is not limited herein.

[0103] Exemplarily, the elastic driving member 63 is configured to drive the wiper strip 50 to move towards the surface 10a to be cleaned, and the transmission mechanism 62 is configured to drive the wiper strip 50 to move away from the surface 10a to be cleaned. When the user pulls the cleaning device 10 backwards, the power member 61 stops outputting driving force to the wiper strip 50, and the elastic driving member 63 drives the wiper strip 50 to move towards the surface 10a to be cleaned, so that the wiper strip 50 moves to contact the surface 10a to be cleaned, and thus the wiper strip 50 can scrape off dirt on the surface 10a to be cleaned along with the action of the user pulling the cleaning device 10 backwards; when the user pushes the cleaning device 10 forwards, the power member 61 overcomes the elastic restoring force of the elastic driving member 63 and drives the wiper strip 50 to move away from the surface 10a to be cleaned through the transmission mechanism 62, so that the wiper strip 50 moves to have a gap with the surface 10a to be cleaned, thereby avoiding the wiper strip 50 from blocking dirt in front of the cleaning device 10.

[0104] In some embodiments, the elastic driving member 63 can be a spring, an elastic rubber, an elastic rope or the like. When the user pulls the cleaning device 10 backwards, the power member 61 stops outputting driving force to the wiper strip 50, and the elastic restoring force provided by the elastic driving member 63 drives the wiper strip 50 to move towards the surface 10a to be cleaned, so that the wiper strip 50 moves to contact the surface 10a to be cleaned, and thus the wiper strip 50 can scrape off dirt on the surface 10a to be cleaned along with the action of the user pulling the cleaning device 10 backwards, and can reduce the dirt remaining on the surface 10a to be cleaned; when the user pushes the cleaning device 10 forwards, the power member 61 overcomes the elastic restoring force of the elastic driving member 63 and drives the wiper strip 50 to move away from the surface 10a to be cleaned through the transmission mechanism 62, so that the wiper strip 50 moves to have a gap with the surface 10a to be cleaned, thereby avoiding the wiper strip 50 from blocking dirt in front of the cleaning device 10, and enabling the cleaning device 10 to efficiently clean the dirt in front.

[0105] Specifically, the elastic driving member 63 can be a compression spring, one end of the elastic driving member 63 is connected to the cover 30, and the other end is connected to the wiper strip 50. When the user pushes the cleaning device 10 forwards, the power member 61 drives the wiper strip 50 to move away from the surface 10a to be cleaned through the transmission mechanism 62, so that the wiper strip 50 moves to have a gap with the surface 10a to be cleaned, and the wiper strip 50 is compressed synchronously with the elastic driving member 63 under the driving of the transmission mechanism 62; when the user pulls the cleaning device 10 backwards, the elastic restoring force provided by the elastic driving member 63 drives the wiper strip 50 to move towards the surface 10a to be cleaned, so that the wiper strip 50 moves to contact the surface 10a to be cleaned.

[0106] The number of the elastic driving members 63 can be one or two or more, and each elastic driving member 63 is distributed along the central axis O of the cleaning member 40. FIG. 8 exemplarily shows the case where the number of the elastic driving members 63 is three, and each elastic driving member 63 cooperates with each other to smoothly drive the wiper strip 50 to move.

[0107] Of course, in other embodiments of the present application, the elastic driving member 63 can also be in the form of a tension spring, etc., and by adaptively adjusting the setting position of the elastic driving member 63, the squeegee 50 can be synchronously stretched during the process that the power member 61 drives the squeegee 50 to move away from the to-be-cleaned surface 10a through the transmission mechanism 62, which is not limited herein.

[0108] In some embodiments, the transmission mechanism 62 comprises a driving member 621 arranged on the cover 30. The power member 61 drives the driving member 621 to move around the central axis O, so that the driving member 621 drives the squeegee 50 to move along the preset movement direction Z. One of the driving member 621 and the elastic driving member 63 is configured to drive the squeegee 50 to move towards the to-be-cleaned surface 10a, and the other is configured to drive the squeegee 50 to move away from the to-be-cleaned surface 10a.

[0109] Based on the above example that the elastic driving member 63 is configured to drive the squeegee 50 to move towards the to-be-cleaned surface 10a, and the transmission mechanism 62 is configured to drive the squeegee 50 to move away from the to-be-cleaned surface 10a, the driving member 621 is configured to drive the squeegee 50 to move away from the to-be-cleaned surface 10a. When the user pulls the cleaning device 10 backward, the power member 61 stops outputting driving force to the squeegee 50, the elastic driving member 63 drives the squeegee 50 to move towards the to-be-cleaned surface 10a, and the driving member 621 follows the driving of the elastic driving member 63, so that the squeegee 50 moves to contact the to-be-cleaned surface 10a, and thus the squeegee 50 can scrape off dirt on the to-be-cleaned surface 10a with the action of the user pulling the cleaning device 10 backward; when the user pushes the cleaning device 10 forward, the power member 61 overcomes the elastic restoring force of the elastic driving member 63 and drives the squeegee 50 to move away from the to-be-cleaned surface 10a through the driving member 621, so that the squeegee 50 moves to have a gap with the to-be-cleaned surface 10a, avoiding that the squeegee 50 blocks dirt in front of the cleaning device 10.

[0110] Optionally, the driving member 621 can be a pull rope, etc., and the driving member 621 is configured to pull the squeegee 50 to move away from the to-be-cleaned surface 10a. The driving member 621 has flexibility, and can move around the central axis O and adaptively bend under the driving of the power member 61. The driving member 621 can be a steel wire rope, etc., that is, the driving member 621 has good wear resistance, which is beneficial to prolong the service life of the transmission mechanism 62.

[0111] Of course, in other embodiments of the present application, the driving member 621 can be configured to drive the scraping strip 50 to move towards the surface 10a to be cleaned, the driving member 621 can have certain rigidity in the length direction thereof, for example, the driving member 621 can be a steel wire, a rigid sheet or the like, so that the driving member 621 can apply a force to the scraping strip 50 to drive the scraping strip 50 to move towards the surface 10a to be cleaned, which is not limited herein. In addition, the transmission mechanism 62 is not limited to driving the scraping strip 50 to move by driving the driving member 621 to move around the central axis O, for example, the transmission mechanism 62 can also drive the scraping strip 50 to move by a linkage structure, a gear structure or the like, which is not limited herein.

[0112] In some embodiments, the transmission mechanism 62 further comprises a first transmission member 622. The first transmission member 622 is arranged on the cover 30, and the first transmission member 622 is in transmission connection with the driving member 621. The first transmission member 622 is configured to be in transmission connection with the power member 61, and the power member 61 drives the driving member 621 through the first transmission member 622.

[0113] When the user pushes the cleaning device 10 forward, the power member 61 drives the first transmission member 622 to move along the preset moving direction X against the elastic restoring force of the elastic driving member 63, and the first transmission member 622 drives the driving member 621 to move around the central axis O, so that the driving member 621 drives the scraping strip 50 to move away from the surface 10a to be cleaned, and then the scraping strip 50 moves to have a gap with the surface 10a to be cleaned, so as to avoid that the scraping strip 50 blocks the dirt in front of the cleaning device 10, as shown in FIG. 10. When the user pulls the cleaning device 10 backward, the power member 61 stops outputting the driving force to the scraping strip 50, and the elastic driving member 63 drives the scraping strip 50 to move towards the surface 10a to be cleaned, and the driving member 621 and the first transmission member 622 move in the opposite direction under the driving of the elastic driving member 63, and the scraping strip 50 moves to contact the surface 10a to be cleaned, so that the scraping strip 50 can scrape the dirt on the surface 10a to be cleaned along with the action of the user pulling the cleaning device 10 backward, as shown in FIG. 9.

[0114] In some embodiments, the transmission mechanism 62 further comprises a second transmission member 623. The second transmission member 623 is arranged on the device main body 20, and the second transmission member 623 is in transmission connection with the power member 61. The second transmission member 623 is configured to be in transmission connection with the first transmission member 622, and the power member 61 drives the first transmission member 622 and the second transmission member 623 to move synchronously along the preset moving direction X to drive the driving member 621 to move around the central axis O.

[0115] When the user pushes the cleaning device 10 forward, the power member 61 overcomes the elastic restoring force of the elastic driving member 63, and drives the first transmission member 622 and the second transmission member 623 to move synchronously in the preset direction of travel X, the first transmission member 622 drives the driving member 621 to move around the central axis O, so that the driving member 621 drives the scraper 50 to move away from the surface to be cleaned 10a, and then the scraper 50 moves to have a gap with the surface to be cleaned 10a, so as to avoid the scraper 50 from blocking the dirt in front of the cleaning device 10, as shown in FIG. 10. When the user pulls the cleaning device 10 backward, the power member 61 stops outputting driving force to the scraper 50, the elastic driving member 63 drives the scraper 50 to move towards the surface to be cleaned 10a, the driving member 621, the first transmission member 622 and the second transmission member 623 move in the opposite direction under the driving of the elastic driving member 63, the scraper 50 moves to contact the surface to be cleaned 10a, so that the scraper 50 can scrape the dirt on the surface to be cleaned 10a with the action of the user pulling the cleaning device 10 backward, as shown in FIG. 9.

[0116] In some embodiments, the power member 61 can be a rudder, a motor or other power element, and the transmission mechanism 62 further includes a third transmission member 626. The third transmission member 626 is arranged on the device main body 20, and the third transmission member 626 is in transmission connection with the power member 61, and the third transmission member 626 is further in transmission connection with the second transmission member 623. The power member 61 is configured to drive the third transmission member 626 to rotate, and the third transmission member 626 drives the first transmission member 622 to move in the preset direction of travel X through the second transmission member 623, that is, the first transmission member 622 and the second transmission member 623 move synchronously in the preset direction of travel X.

[0117] When the user pushes the cleaning device 10 forward, the power member 61 drives the third transmission member 626 to rotate against the elastic restoring force of the elastic driving member 63, the third transmission member 626 drives the first transmission member 622 and the second transmission member 623 to move synchronously in the preset advancing direction X, the first transmission member 622 drives the driving member 621 to move around the central axis O, so that the driving member 621 drives the scraping strip 50 to move away from the surface 10a to be cleaned, and then the scraping strip 50 moves to a position where a gap exists between the scraping strip 50 and the surface 10a to be cleaned, so as to avoid the scraping strip 50 from blocking dirt in front of the cleaning device 10, as shown in FIG. 10; after the scraping strip 50 is moved to the position, the power member 61 is self-locked to limit the third transmission member 626 from continuing to rotate, so as to keep the gap between the scraping strip 50 and the surface 10a to be cleaned; when the user pulls the cleaning device 10 backward, the power member 61 stops outputting driving force to the scraping strip 50, the elastic driving member 63 drives the scraping strip 50 to move toward the surface 10a to be cleaned, the power member 61 is unlocked to allow the third transmission member 626 to rotate in the reverse direction, the driving member 621, the first transmission member 622 and the second transmission member 623 move in the reverse direction under the driving of the elastic driving member 63, and the scraping strip 50 moves to contact the surface 10a to be cleaned, so that the scraping strip 50 can scrape dirt on the surface 10a to be cleaned along with the action of the user pulling the cleaning device 10 backward, as shown in FIG. 9.

[0118] Optionally, referring to FIG. 11, the third transmission member 626 is provided with a waist-shaped hole 6261, and the second transmission member 623 is provided with a transmission column 6231, which is movably embedded in the waist-shaped hole 6261. When the power member 61 drives the third transmission member 626 to rotate, the transmission column 6231 can move along the waist-shaped hole 6261, and the third transmission member 626 drives the second transmission member 623 to move in the preset advancing direction X through the transmission column 6231. It can be understood that the transmission connection between the second transmission member 623 and the third transmission member 626 is not limited to the waist-shaped hole 6261 and the transmission column 6231, for example, the transmission connection between the second transmission member 623 and the third transmission member 626 can also be achieved by a slider and a slide rail, which is not limited herein.

[0119] Please continue to refer to FIG. 11. In some embodiments, the cover 30 and the device body 20 are detachably connected. When the user needs to maintain the cleaning device 10 or replace the cleaning member 40, the cover 30 can be detached from the device body 20, so as to facilitate the user to maintain the cleaning device 10 or replace the cleaning member 40.

[0120] To adapt the detachable connection design of the cover 30 and the device main body 20, the first transmission member 622 is configured to be detachably in transmission connection with the power member 61, specifically, the first transmission member 622 is detachably in transmission connection with the second transmission member 623. When the cover 30 is installed on the device main body 20, the first transmission member 622 can be in transmission connection with the second transmission member 623, so that the driving force provided by the power member 61 can act on the first transmission member 622 through the second transmission member 623, so that the first transmission member 622 can drive the driving member 621 to drive the scraping strip 50 to move. When the user detaches the cover 30 from the device main body 20, the first transmission member 622 and the second transmission member 623 can be disconnected, avoiding the transmission connection between the first transmission member 622 and the second transmission member 623 limiting the detachable design between the cover 30 and the device main body 20.

[0121] Optionally, one of the first transmission member 622 and the second transmission member 623 is provided with a connecting column 624, and the other is provided with a connecting hole 625, and the connecting column 624 is detachably embedded in the connecting hole 625. FIG. 11 exemplarily shows that the first transmission member 622 is provided with the connecting column 624, and the second transmission member 623 is provided with the connecting hole 625. When the cover 30 is installed on the device main body 20, the connecting column 624 is embedded in the connecting hole 625, so that the transmission connection is established between the first transmission member 622 and the second transmission member 623; and when the user detaches the cover 30 from the device main body 20, the connecting column 624 is separated from the connecting hole 625 with the first transmission member 622, and the transmission connection between the first transmission member 622 and the second transmission member 623 is disconnected. The detachable transmission mode of the connecting column 624 and the connecting hole 625 in the embodiment has simple structure and good stability, which is conducive to prolonging the service life of the driving assembly 60 and reducing the cost.

[0122] Of course, in other embodiments of the application, the detachable transmission mode between the first transmission member 622 and the second transmission member 623 is not limited to the cooperation of the connecting column 624 and the connecting hole 625, for example, the detachable transmission between the first transmission member 622 and the second transmission member 623 can also be achieved by buckling, magnetic attraction and the like, which is not limited herein.

[0123] Please refer to FIG. 12, which is a structural schematic diagram of an embodiment of the base body of the application.

[0124] In some embodiments, at least part of the driving member 621 is embedded in the cover 30. In this way, the influence of the driving member 621 on the front volume of the cleaning device 10 can be reduced, which is conducive to ensuring the cleaning performance of the cleaning device 10, for example, being conducive to the cleaning device 10 entering the low area under the bed, under the sofa, under the table and chair, etc. for cleaning. In addition, the influence of the driving member 621 on the product appearance of the cleaning device 10 can also be reduced.

[0125] Specifically, the interior of the cover 30 is provided with a guide channel 311 extending around the central axis O, and the driving member 621 is movably arranged in the guide channel 311.

[0126] When the user pushes the cleaning device 10 forward, the power member 61 drives the driving member 621 to move along the guide channel 311, so that the driving member 621 moves around the central axis O, and the driving member 621 drives the scraping strip 50 to move away from the surface 10a to be cleaned, so that the scraping strip 50 moves to a gap from the surface 10a to be cleaned, avoiding the scraping strip 50 from blocking the dirt in front of the cleaning device 10; when the user pulls the cleaning device 10 backward, the power member 61 stops outputting driving force to the scraping strip 50, and the driving member 621 moves in the opposite direction along the guide channel 311 under the driving of the elastic driving member 63, and the scraping strip 50 moves toward the surface 10a to be cleaned, and the scraping strip 50 moves to contact the surface 10a to be cleaned, so that the scraping strip 50 can scrape the dirt on the surface 10a to be cleaned with the action of the user pulling the cleaning device 10 backward.

[0127] Of course, in other embodiments of the present application, the driving member 621 can also be arranged on the side of the cover 30 facing the cleaning member 40, and the driving member 621 is not exposed outside the cleaning device 10, which can also reduce the influence of the driving member 621 on the appearance of the cleaning device 10, which is not limited herein.

[0128] In some embodiments, as shown in FIG. 8, the driving assembly 60 further comprises a protective sleeve 64 arranged in the guide channel 311 and sleeved on the outer periphery of the driving member 621. The protective sleeve 64 of the present embodiment can reduce the wear of the driving member 621 and the cover 30 caused by the relative movement between the driving member 621 and the cover 30. Especially based on the above-mentioned example that the driving member 621 is a steel wire rope, the hardness of the driving member 621 is relatively high, and if the protective sleeve 64 is not arranged, the driving member 621 is easy to cause the wear of the cover 30.

[0129] In some embodiments, as shown in FIGS. 8 and 12, the cover 30 comprises a base body 31 provided with the guide channel 311. The base body 31 is further provided with a first operation opening 312 in communication with the guide channel 311, and the first operation opening 312 is located at the rear end of the guide channel 311 in the preset movement direction X. The user installs the driving member 621 through the first operation opening 312, which can facilitate the user to install the driving member 621 into the guide channel 311 on the base body 31.

[0130] The cover body 30 further comprises a first cover portion 32 detachably covered on the side of the base body 31 facing the cleaning member 40, and the first cover portion 32 is used for closing the first operation opening 312. When it is needed to install the driving member 621 into the guide channel 311, the user detaches the first cover portion 32 from the base body 31, and then installs the driving member 621 into the guide channel 311 on the base body 31. After the driving member 621 is installed in place, the user installs the first cover portion 32 on the base body 31 to close the first operation opening 312. The first cover portion 32 can block the external dirt from entering the guide channel 311, avoid the dirt from entering the guide channel 311 to affect the movement of the driving member 621 in the guide channel 311, and is conducive to ensuring the smoothness of the movement of the driving member 621 and further conducive to ensuring the response speed of the action of the scraping strip 50.

[0131] In some embodiments, as shown in FIG. 8, the base body 31 further has a second operation opening 313 in communication with the guide channel 311, and the second operation opening 313 is located at the front end of the guide channel 311 in the preset travel direction X. The user installs the driving member 621 through the second operation opening 313. The cover body 30 further comprises a second cover portion 33 detachably covered on the side of the base body 31 away from the cleaning member 40, and the second cover portion 33 is used for closing the second operation opening 313.

[0132] When the user needs to install the driving member 621, the user detaches the second cover portion 33 from the base body 31, and then installs the driving member 621 into the guide channel 311 on the base body 31. After the driving member 621 is installed in place, the user installs the second cover portion 33 on the base body 31 to close the second operation opening 313. The second cover portion 33 can block the external dirt from entering the guide channel 311, avoid the dirt from entering the guide channel 311 to affect the movement of the driving member 621 in the guide channel 311, and is conducive to ensuring the smoothness of the movement of the driving member 621 and further conducive to ensuring the response speed of the action of the scraping strip 50.

[0133] For example, the number of driving members 621 can be one or two or more, and each driving member 621 is distributed along the central axis O of the cleaning member 40. FIG. 8 exemplarily shows the case where the number of driving members 621 is three. Different guide channels 311 are respectively arranged on the cover 30 for each driving member 621, i.e., each driving member 621 is arranged in a different guide channel 311. By arranging multiple driving members 621, each driving member 621 cooperates with each other to drive the movement of the wiper strip 50, which is conducive to ensuring the stability of the movement of the wiper strip 50. The guide channel 311 corresponding to each driving member 621 is provided with a protective sleeve 64, and the guide channel 311 is provided with a protective sleeve 64 at both ends in the preset travel direction X. The plurality of driving members 621 are connected to the first transmission member 622, and the first transmission member 622 synchronously drives the movement of each driving member 621. Compared with the case where a transmission member is arranged for each driving member 621, the embodiment can simplify the structure of the transmission mechanism 62, which is conducive to the miniaturization design of the cleaning device 10 and reduces the cost of the cleaning device 10.

[0134] Please refer to FIGS. 13-15 together. FIG. 13 is a structural schematic diagram of an embodiment of the device main body of the application. FIG. 14 is a structural schematic diagram of the device main body of FIG. 13 without a transmission cover. FIG. 15 is a structural schematic diagram of an embodiment of the transmission cover of the application.

[0135] In some embodiments, the device main body 20 includes a base 21 provided with a receiving cavity 211 and a first opening 212 communicating with the receiving cavity 211. The power member 61 is arranged in the receiving cavity 211, and the first opening 212 exposes the second transmission member 623. FIG. 14 exemplarily shows the case where the first opening 212 exposes the second transmission member 623 and the third transmission member 626.

[0136] The device main body 20 further includes a transmission cover 22. The transmission cover 22 is arranged on the first opening 212. The transmission cover 22 is provided with a second opening 222 communicating with the first opening 212, and the first transmission member 622 and the second transmission member 623 are drivingly connected through the second opening 222. When the transmission cover 22 is arranged on the first opening 212, the second opening 222 exposes the part of the second transmission member 623 provided with the connecting hole 625. When the cover 30 is installed on the device main body 20, the connecting column 624 on the first transmission member 622 can be embedded in the connecting hole 625, so that the transmission connection between the first transmission member 622 and the second transmission member 623 is established.

[0137] In some embodiments, the inner portion of the transmission cover 22 is provided with a guide slot 221 extending along the preset travel direction X, and the second transmission member 623 is movably embedded in the guide slot 221. The guide slot 221 in this embodiment is configured to guide the second transmission member 623 to move along the preset travel direction X, so that the first transmission member 622 and the second transmission member 623 can stably move along the preset travel direction X, thereby stably driving the driving member 621 to drive the wiper strip 50 to move. Of course, a guide structure can also be provided between the first transmission member 622 and the cover body 30 to guide the first transmission member 622 to move along the preset travel direction X, further enabling the first transmission member 622 and the second transmission member 623 to stably move along the preset travel direction X, and further facilitating the stable driving of the driving member 621 to drive the wiper strip 50 to move.

[0138] In some embodiments, as shown in FIG. 5, the wiper strip 50 includes a hard portion 51 and a flexible cleaning portion 52. The hard portion 51 is in transmission cooperation with the driving member 621 and the elastic driving member 63. The flexible cleaning portion 52 is connected to the hard portion 51, and is used to contact the to-be-cleaned surface 10a to scrape off dirt on the to-be-cleaned surface 10a.

[0139] In this way, the hardness of the hard portion 51 is greater than that of the flexible cleaning portion 52. The hard portion 51 and the flexible cleaning portion 52 can be formed as a whole by injection molding or the like. The wiper strip 50 is in transmission cooperation with the driving member 621 and the elastic driving member 63 through the hard portion 51, so that the wiper strip 50 can quickly perform corresponding actions in response to the driving force provided by the driving member 621 and the elastic driving member 63, further facilitating the improvement of the response speed of the wiper strip 50 and the stability and reliability of the transmission cooperation process of the wiper strip 50 with the driving member 621 and the elastic driving member 63. The flexible cleaning portion 52, as its name implies, has a soft texture and is easy to deform under external force. The wiper strip 50 scrapes off dirt on the to-be-cleaned surface 10a through the flexible cleaning portion 52. The flexible cleaning portion 52 contacts the to-be-cleaned surface 10a and maintains a certain interference amount therebetween, so that the flexible cleaning portion 52 can efficiently scrape off dirt on the to-be-cleaned surface 10a, and at the same time, the soft texture of the flexible cleaning portion 52 can reduce the risk of wear of the flexible cleaning portion 52 and the to-be-cleaned surface 10a.

[0140] In some embodiments, the flexible cleaning portion 52 includes a connecting sub-portion 521 and a cleaning sub-portion 522. The connecting sub-portion 521 is connected to the hard portion 51. The cleaning sub-portion 522 is connected to the connecting sub-portion 521 and is closer to the to-be-cleaned surface 10a than the connecting sub-portion 521. The cleaning sub-portion 522 extends towards the front side of the cover body 30 (i.e. the front side of the cover body 30 in the preset travel direction X) and towards the to-be-cleaned surface 10a.

[0141] In this way, the cleaning sub-part 522 of the flexible cleaning part 52 extends forwardly and obliquely. For a cleaning scenario of an edge area such as a wall edge or a furniture edge, taking the wall edge as an example, after the cleaning device 10 is close to the wall, the driving member 621 drives the scraping strip 50 to move towards the cleaning surface 10a, the cleaning sub-part 522 is further close to the wall, and the dirt on the wall edge is scraped off by the cleaning sub-part 522, so that the cleaning effect of the edge area can be further improved.

[0142] In some embodiments, the cover 30 is provided with a guide groove 35 extending along the preset moving direction, and the hard part 51 is movably embedded in the guide groove 35. The guide groove 35 guides the scraping strip 50 to move along the preset moving direction through the hard part 51, so that the scraping strip 50 moves along the predetermined path, and the movement of the scraping strip 50 is more controllable and stable. Moreover, the hard part 51 is hard in texture, which is beneficial to ensure the stability and reliability of the movement of the scraping strip 50 guided by the guide groove 35.

[0143] The technical solutions provided by the embodiments of the present application will be described below in conjunction with specific embodiments.

[0144] Embodiment one:

[0145] The cleaning device 10 is a scrubber. The cleaning device 10 comprises a device main body 20, which can move on a cleaning surface 10a along a preset advancing direction X. The cleaning device 10 further comprises a cover 30, which is arranged at the front end of the device main body 20 in the preset advancing direction X. The cleaning device 10 further comprises a cleaning member 40, which is close to the cleaning surface 10a relative to at least part of the cover 30; the cleaning member 40 has a central axis O and a central cross section a, the central axis O is located on the central cross section a, and the central cross section a is perpendicular to the preset advancing direction X. The cleaning device 10 further comprises a scraping strip 50, which is arranged on the cover 30, and the scraping strip 50 is located on the front side of the cleaning member 40 in the preset advancing direction X. The cleaning device 10 further comprises a driving assembly 60, which comprises a power member 61 and a driving member 621, at least part of the power member 61 is located on the rear side of the central cross section a in the preset advancing direction X, and the driving member 621 is arranged on the cover 30; the power member 61 drives the driving member 621 to move around the central axis O, so that the driving member 621 drives the scraping strip 50 to move in a direction intersecting the cleaning surface 10a.

[0146] The driving assembly 60 of the cleaning device 10 is used to drive the scraping strip 50 to move along the preset movement direction Z, so as to scrape off the dirt on the surface 10a to be cleaned by the scraping strip 50, thereby reducing the dirt residues on the surface 10a to be cleaned. In particular, the scraping strip 50 is located at the front side of the cleaning member 40, so that when the user pulls the cleaning device 10 backward to clean, the scraping strip 50 can scrape off the dirt on the surface 10a to be cleaned, thereby reducing the dirt residues on the surface 10a to be cleaned when the user pulls the cleaning device 10 backward to clean.

[0147] The at least part of the power member 61 is located at the rear side of the central section a of the cleaning member 40, i.e., the power member 61 is arranged rearward in the cleaning device 10, which can reduce the influence of the power member 61 on the front volume of the cleaning device 10, and is conducive to ensuring the cleaning performance of the cleaning device 10, such as facilitating the cleaning device 10 to enter the low area under the bed, under the sofa, under the table and chair, etc. In addition, the power member 61 is arranged rearward in the cleaning device 10, and the power member 61 is not arranged at the front of the cleaning device 10, so that the influence of the driving assembly 60 on the product appearance of the cleaning device 10 can be reduced.

[0148] Embodiment two:

[0149] The power member 61 is located at the rear side of the cleaning member 40 in the preset movement direction X. Specifically, the power member 61 is arranged on the device body 20. The power member 61 is arranged rearward in the cleaning device 10, which can reduce the influence of the power member 61 on the front volume of the cleaning device 10, and is conducive to ensuring the cleaning performance of the cleaning device 10 and reducing the influence of the driving assembly 60 on the product appearance of the cleaning device 10.

[0150] Embodiment three:

[0151] The driving assembly 60 further comprises an elastic reset member. The elastic reset member is arranged on the cover 30, and the elastic reset member is in transmission cooperation with the scraping strip 50. One of the driving member 621 and the elastic reset member is configured to drive the scraping strip 50 to move towards the surface 10a to be cleaned, and the other is configured to drive the scraping strip 50 to move away from the surface 10a to be cleaned.

[0152] The power member 61 is configured to stop outputting driving force to the wiper strip 50 when the elastic driving member 63 drives the wiper strip 50. When the elastic driving member 63 drives the wiper strip 50 to move, the power member 61 does not output driving force to the wiper strip 50, which can reduce the working load of the power member 61, thereby prolonging the service life of the power member 61. The power member 61 can be a steering engine, a motor or the like. The power member 61 works in response to a corresponding control signal. Since there is a certain delay in the transmission of the signal, and there is also a certain hysteresis in the driving of the transmission mechanism 62 by the power member 61, when the elastic driving member 63 drives the wiper strip 50 to move, the power member 61 does not output driving force to the wiper strip 50, and the elastic driving member 63 can immediately drive the wiper strip 50 to move, that is, the elastic driving member 63 drives the wiper strip 50 to move in a manner with a faster response speed, which is beneficial to improving the response speed of the action of the wiper strip 50. Moreover, by reasonably selecting the elastic coefficient of the elastic driving member 63, the elastic driving member 63 can provide appropriate driving force to the wiper strip 50, which further enables the wiper strip 50 to move in response to the driving force provided by the elastic driving member 63 quickly, thereby further improving the response speed of the action of the wiper strip 50.

[0154] The elastic driving member 63 is configured to drive the wiper strip 50 to move towards the surface to be cleaned 10a; the driving member 621 is a pull rope, and the driving member 621 is configured to pull the wiper strip 50 to move away from the surface to be cleaned 10a.

[0155] When the user pulls the cleaning device 10 backward, the power member 61 stops outputting driving force to the wiper strip 50, and the elastic driving member 63 drives the wiper strip 50 to move towards the surface to be cleaned 10a, so that the wiper strip 50 moves to contact the surface to be cleaned 10a, and thus the wiper strip 50 can scrape off dirt on the surface to be cleaned 10a along with the action of the user pulling the cleaning device 10 backward; when the user pushes the cleaning device 10 forward, the power member 61 overcomes the elastic restoring force of the elastic driving member 63 and drives the wiper strip 50 to move away from the surface to be cleaned 10a through the driving member 621, so that the wiper strip 50 moves to have a gap with the surface to be cleaned 10a, thereby avoiding that the wiper strip 50 blocks dirt in front of the cleaning device 10.

[0156] Embodiment five:

[0157] The cover 30 is detachably connected with the device main body 20, and the power member 61 is arranged on the device main body 20. When the user needs to maintain the cleaning device 10 or replace the cleaning member 40, the cover 30 can be detached from the device main body 20, so as to facilitate the user to maintain the cleaning device 10 or replace the cleaning member 40.

[0159] When the user pushes the cleaning device 10 forward, the power member 61 overcomes the elastic restoring force of the elastic driving member 63 and drives the first transmission member 622 to move along the preset moving direction X, the first transmission member 622 drives the driving member 621 to move around the central axis O, so that the driving member 621 drives the scraping strip 50 to move away from the surface to be cleaned 10a, and then the scraping strip 50 moves to have a gap with the surface to be cleaned 10a, so as to avoid the scraping strip 50 from blocking the dirt in front of the cleaning device 10; when the user pulls the cleaning device 10 backward, the power member 61 stops outputting driving force to the scraping strip 50, the elastic driving member 63 drives the scraping strip 50 to move towards the surface to be cleaned 10a, the driving member 621 and the first transmission member 622 move in the opposite direction under the driving of the elastic driving member 63, and the scraping strip 50 moves to contact the surface to be cleaned 10a, so that the scraping strip 50 can scrape the dirt on the surface to be cleaned 10a with the action of the user pulling the cleaning device 10 backward. In order to adapt to the detachable connection design of the cover body 30 and the device main body 20, the first transmission member 622 is configured to be detachably in transmission connection with the power member 61.

[0162] When the cover body 30 is installed on the device main body 20, the first transmission member 622 can be in transmission connection with the second transmission member 623, so that the driving force provided by the power member 61 can act on the first transmission member 622 through the second transmission member 623, and the first transmission member 622 can drive the driving member 621 to drive the scraping strip 50 to move. When the user detaches the cover body 30 from the device main body 20, the first transmission member 622 and the second transmission member 623 can be disconnected in transmission, so as to avoid that the transmission connection between the first transmission member 622 and the second transmission member 623 limits the detachable design between the cover body 30 and the device main body 20.

[0163] Embodiment seven:

[0164] The cleaning device 10 is a floor cleaning machine. The cleaning device 10 comprises a device body 20, which is movable on a to-be-cleaned surface 10a in a preset moving direction X.
