[0030] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0031] See also Figures 1 to 5The embodiment of the present application provides a cleaning device 100, which includes a cleaning member 10, an auxiliary member 20 and a power-assisting member 30. The cleaning member 10 includes a cleaning end 10a for contacting with a surface to be cleaned 200 and for cleaning the surface to be cleaned 200. The auxiliary member 20 is disposed on one side of the cleaning member 10, and the auxiliary member 20 is used to assist the cleaning member 10 in cleaning the surface to be cleaned 200. The cleaning member 10 is configured to be able to move relative to the auxiliary member 20 to adjust the gap between the cleaning member 10 and the auxiliary member 20 and / or the surface to be cleaned 200.

[0032] The power-assisting member 30 can provide driving force and has a power-assisting state and an unlocking state. In the power-assisting state, the power-assisting member 30 is used to apply a force to the cleaning member 10 to increase the force of the cleaning end 10a on the surface to be cleaned 200, while limiting the cleaning member 10 from adjusting the gap between the auxiliary member 20 and / or the surface to be cleaned 200. In the unlocking state, the power-assisting member 30 is used to release the force applied to the cleaning member 10, so that the cleaning member 10 can adjust the gap between the auxiliary member 20 and / or the surface to be cleaned 200.

[0033] The cleaning device 100 proposed in the embodiment of the present application includes a cleaning component 10, an auxiliary component 20 and a power-assisting component 30. Among them, the cleaning component 10 includes a cleaning end 10a for contacting with the surface to be cleaned 200 and for cleaning the surface to be cleaned 200. In the power-assisting state, the power-assisting component 30 can provide a driving force and apply a force to the cleaning component 10 to increase the force of the cleaning end 10a on the surface to be cleaned 200, thereby, the friction force generated by the cleaning end 10a when rubbing the surface to be cleaned 200 is greater, and the stubborn stains on the surface to be cleaned 200 can be cleaned more fully, and the cleaning effect is better.

[0034] Optionally, the assisting member 30 may adopt a motor or other power source capable of providing driving force. The driving force provided by the assisting member 30 may directly act on the cleaning member 10 through its output shaft 311, or may indirectly act on the cleaning member 10 through intermediate elements such as a connector 32, so that the cleaning member 10 is pressed downward or a downward torque is applied to the cleaning member 10, thereby increasing the force of the cleaning end 10a on the surface 200 to be cleaned.

[0035] For example, when the cleaning device 100 is in use, whether the power-assisting member 30 is in the power-assisting state or the unlocked state, the cleaning end 10a can contact the surface to be cleaned 200, and the surface to be cleaned 200 is rubbed by the cleaning end 10a to clean the stains on the surface to be cleaned 200. It can be understood that when the surface to be cleaned 200 is a horizontal surface such as the ground, most of the pressure of the cleaning member 10 on the surface to be cleaned 200 comes from its own gravity. If the power-assisting member 30 is not used for power-assisting, the cleaning force is insufficient, and it is difficult to fully clean the surface to be cleaned 200, which affects the cleaning effect. When the power-assisting member 30 is in the power-assisting state, it can provide driving force and apply force to the cleaning member 10 to increase the force of the cleaning end 10a on the surface to be cleaned 200, so that the surface to be cleaned 200 can be cleaned more fully and stubborn stains can be better removed. In actual application, when there is no need to mop stubborn stains, the assisting member 30 can be operated to the unlocked state, thereby releasing the force applied to the cleaning member 10. At this time, without the force of the assisting member 30, the cleaning member 10 can adjust the gap between the auxiliary member 20 and / or the surface to be cleaned 200, thereby achieving the effect that the cleaning member 10 can automatically adjust the gap between the auxiliary member 20 and / or the surface to be cleaned 200 according to the size of the garbage, so that the cleaning device 100 can remove garbage of different sizes.

[0036] In some usage scenarios, the surface to be cleaned 200 may also be an inclined slope, or may be a vertical wall or other surface to be cleaned. At this time, the pressure of the cleaning component 10 on the surface to be cleaned is not equal to its own gravity, but through the setting of the power-assisting component 30, the force of the cleaning end 10a on the surface to be cleaned 200 may also be increased. For example, when the surface to be cleaned 200 is a vertical wall, the cleaning component 10 will also apply pressure to the wall with the help of the power-assisting component 30 so that the cleaning end 10a can drag the stains on the wall. The power-assisting component 30 provides a driving force and applies a force to the cleaning component 10, thereby increasing the force of the cleaning end 10a on the wall, that is, increasing the friction when the cleaning end 10a drags the wall.

[0037] In an optional embodiment, the body of the cleaning device 100 may be provided with a button, which is used to control the working state of the power-assisting member 30, so that the power-assisting member 30 switches between the power-assisting state and the unlocked state. When the cleaning device 100 is a handheld cleaning device, the button may be provided at the handle of the upper part of the handheld rod 60 thereof, so as to facilitate the user's use.

[0038] See also Figure 5In an optional embodiment, the auxiliary component 20 is arranged behind the cleaning component 10 along the forward direction of the cleaning device 100. Exemplarily, the forward direction of the cleaning device 100 is the main moving direction of the cleaning device 100 when working. If the cleaning device 100 is a handheld cleaning device 100 and the surface 200 to be cleaned is the ground, the user needs to hold the cleaning device 100 and push the cleaning device 100 in the direction of the user's forward movement, then the direction is the forward direction of the cleaning device 100. In other embodiments, if the cleaning device 100 is a cleaning robot, then its forward direction is the main moving direction of the cleaning robot.

[0039] See also Figures 6 to 9 In an optional embodiment, the cleaning member 10 includes an endless belt 11, a first roller 12 and a second roller 13, wherein the first roller 12 and the second roller 13 are arranged at intervals and the second roller 13 is arranged obliquely above the first roller 12, and the endless belt 11 is rotatably surrounded by the first roller 12 and the second roller 13; wherein the first roller 12 is used to press a local portion of the endless belt 11 against the surface to be cleaned 200 to form a cleaning end 10a, and the second roller 13 forms a rotating shaft 14 of the cleaning member 10. wherein the first roller 12 and the second roller 13 tighten the endless belt 11 to form an inclined conveying side 111, and the conveying side 111 is at least partially arranged opposite to the auxiliary member 20, so as to cooperate with the auxiliary member 20 to convey garbage. The endless belt 11 is rotatably encircled outside the first roller 12 and the second roller 13, which means that the endless belt 11 is rotatable relative to the first roller 12 and the second roller 13 as a whole. It can be understood that when the cleaning device 100 is working, the endless belt 11 is cyclically rotated around the first roller 12 and the second roller 13, and the direction of rotation of the endless belt 11 enables the garbage to be brought from the cleaning end 10a to the conveying side 111. During the operation of the cleaning device 100, since the cleaning component 10 is rotatably arranged on the auxiliary component 20 through the rotating member 40, when the power-assisting component 30 is in the unlocked state, the cleaning component 10 can adjust the gap between the surface to be cleaned 200 and the auxiliary component 20. Specifically, when the endless belt 11 rotates, it can carry the garbage on the surface to be cleaned 200 under the action of friction. If it encounters larger garbage, the cleaning end 10a will abut against the garbage, and the larger garbage will cause the cleaning component 10 to be lifted up by the garbage (at this time, the cleaning component 10 may temporarily leave the surface to be cleaned 200, but under the action of its gravity, it will contact the surface to be cleaned 200 again), thereby adjusting the gap between the cleaning end 10a of the cleaning component 10 and the surface to be cleaned 200, so that the garbage can have enough space to pass through between the cleaning end 10a and the surface to be cleaned 200, and be transmitted to between the transmission side 111 and the auxiliary component 20. At this time, due to the rotation setting of the cleaning component 10 and the auxiliary component 20, the gap between the transmission side 111 and the auxiliary component 20 can also be adjusted according to the size of the garbage, thereby facilitating the transmission of the garbage.

[0040] In an optional embodiment, the cleaning device 100 further includes a rotating member 40, and the cleaning member 10 is rotatably disposed on the auxiliary member 20 through the rotating member 40, so that the cleaning member 10 can adjust the gap with the auxiliary member 20 and / or the surface to be cleaned 200. Exemplarily, the cleaning member 10 can adjust the gap with the auxiliary member 20, or the gap with the surface to be cleaned 200, or the gap between the auxiliary member 20 and the surface to be cleaned 200. Thus, the cleaning member 10 can automatically adjust the gap with the auxiliary member 20 and / or the surface to be cleaned 200 according to the size of the garbage, so that the cleaning device 100 can remove garbage of different sizes.

[0041] That is, in an optional embodiment, the assisting member 30 can be an active assisting structure through a power source, etc., which can apply a force to the cleaning member 10 through the power source in an assisting state (assisting state), and the force can be a torsional force or linear pressure applied directly or indirectly, etc.

[0042] In other embodiments, the assisting component 30 may also have a locking mechanism, which can lock the cleaning component 10 and the auxiliary component 20 (assisting state) so that the assisting component 30 and the auxiliary component 20 cannot rotate relative to each other. Specifically, the assisting component 30 and the rotating part 40 can be locked and / or the rotating part 40 and the auxiliary component 20 can be locked, so that the gravity or pressure of the auxiliary component 20 or the non-cleaning component part of the cleaning device 100 can be applied to the cleaning component 10 through the assisting component 30, thereby increasing the force of the cleaning end 10a on the cleaning surface 200, that is, passively applying force to the cleaning component 10, which is not limited here.

[0043] Optionally, since the cleaning component 10 is arranged on the auxiliary component 20 through the rotating part 40, neither the gravity on the auxiliary component 20 nor the gravity of other non-cleaning component parts of the cleaning device 100 can be transmitted to the cleaning component 10 due to the rotating part 40, and even if pressure is applied to other non-cleaning component parts of the cleaning device 100, it cannot be transmitted to the cleaning component 10. Therefore, most of the pressure of the cleaning component 10 on the surface to be cleaned comes from its own gravity. When the surface to be cleaned is relatively dirty, the cleaning force is insufficient, and it is difficult to fully clean the surface to be cleaned, which affects the cleaning effect.

[0044] Therefore, by providing the assisting member 30, in the assisting state, the assisting member 30 can provide driving force and apply force to the cleaning member 10 to increase the force of the cleaning end 10a on the surface to be cleaned 200, or the assisting member 30 can also lock the cleaning member 10 and the auxiliary member 20 (assisting state) so that the assisting member 30 and the auxiliary member 20 cannot rotate relative to each other, so that the gravity or pressure of the auxiliary member 20 or the non-cleaning member part of the cleaning device 100 can be applied to the cleaning member 10 through the assisting member 30, thereby increasing the force of the cleaning end 10a on the surface to be cleaned 200. As a result, the friction force generated by the cleaning end 10a when rubbing the surface to be cleaned 200 is greater, and the stubborn stains on the surface to be cleaned 200 can be cleaned more fully, and the cleaning effect is better.

[0045] It should be noted that the cleaning component 10 can be rotated by the rotating member 40 to adjust the gap between the auxiliary component 20 and / or the surface to be cleaned 200, and the gap can be increased or decreased, so that the gap can be adapted to garbage of different sizes. Thus, the cleaning component 10 can not only transfer small-volume garbage to between the endless belt 11 and the auxiliary component 20, but also transfer large-volume garbage to between the endless belt 11 and the auxiliary component 20, effectively ensuring the cleaning effect of the cleaning device 100 in cleaning the garbage on the surface to be cleaned 200.

[0046] In an optional embodiment, the rotating member 40 is located at both ends of the second roller 13 along the axial direction. The rotating member 40 can be a convex shaft 41 arranged at both ends of the second roller 13, and the auxiliary component 20 is provided with a rotating groove 21 that rotates with the convex shaft 41, thereby enabling relative rotation between the cleaning component 10 and the auxiliary component 20.

[0047] See also Figure 2In an optional embodiment, the power-assisting member 30 includes a driving member 31, and an output shaft 311 of the driving member 31 is connected to the rotating member 40. In the power-assisting state, the output shaft 311 of the driving member 31 outputs torque to the rotating member 40, and applies a force to the cleaning member 10 through the rotating member 40, or the output shaft 311 of the driving member 31 is locked with the rotating member 40 to limit the rotation of the cleaning member 10. In the unlocked state, the output shaft 311 of the driving member 31 stops outputting torque and allows the rotating member 40 to rotate freely to release the force applied to the cleaning member 10. Exemplarily, the rotating member 40 can be fixedly connected to the rotating shaft 14 of the cleaning component 10, and the output shaft 311 of the driving member 31 is connected to the rotating member 40, so that when the output shaft 311 of the driving member 31 outputs torque, the downward torque can be transmitted to the cleaning component 10 through the rotating member 40. At this time, the cleaning component 10 can have a downward rotation to increase the friction with the surface 200 to be cleaned. It is also possible that when the cleaning component 10 is already in contact with the surface 200 to be cleaned, the downward torque is added to the cleaning component 10, so that the cleaning component 10 has no actual rotation and the friction with the surface 200 to be cleaned is increased, so that stubborn stains can be cleaned. When the stubborn stains are cleaned, the driving member 31 can be in an unlocked state. At this time, the output shaft 311 stops outputting torque and allows the rotating member 40 to rotate freely, that is, the cleaning component 10 can rotate freely, so that the cleaning component 10 can adjust the gap between the auxiliary component 20 and / or the surface 200 to be cleaned.

[0048] In an optional embodiment, the driving member 31 has a first state, a second state and a third state. In the first state, the output shaft 311 of the driving member 31 outputs torque to the rotating member 40. In the second state, the driving member 31 locks the output shaft 311 to limit the rotation of the rotating member 40, thereby limiting the rotation of the cleaning member 10, so that the cleaning member 10 cannot rotate relative to the auxiliary member 20 (i.e., the relative rotation of the cleaning member 10 and the auxiliary member 20 is locked), which is equivalent to locking the auxiliary member 20 with the cleaning member 10, so that some gravity or pressure of the auxiliary member 20 and other components of the cleaning device 100 can act on the cleaning member 10, so as to increase the pressure of the cleaning member 10 on the surface 200 to be cleaned, so as to improve the cleaning effect. In the third state, the driving member 31 unlocks the output shaft 311 so that the rotating member 40 can rotate freely. Exemplarily, when the driving member 31 is a motor, the above three states can be set. In the power-assisted state, the motor can be started in the first state, at which time its output shaft 311 gradually increases the output torque to the preset output torque and transmits it to the rotating member 40, so that the cleaning component 10 has sufficient downward pressure to clean stubborn stains. In the power-assisted state, the motor can also be in the second state, at which time the output shaft 311 is locked to limit the rotation of the rotating member 40, thereby limiting the rotation of the cleaning component 10, so as to lock the auxiliary component 20 with the cleaning component 10, and also apply a force to the cleaning component 10, thereby increasing the pressure of the cleaning component 10 on the surface 200 to be cleaned. When the stubborn stains are cleaned, the driving member 31 can be in the unlocked state, and the motor is converted to the third state. At this time, the motor unlocks the output shaft 311 so that the output shaft 311 can rotate freely, thereby allowing the rotating member 40 to rotate freely.

[0049] Optionally, the first state and the second state of the driving member 31 correspond to the assisting state, and the third state corresponds to the unlocking state.

[0050] See also Figure 3 In an optional embodiment, the two opposite ends of the rotating shaft 14 of the cleaning member 10 are provided with rotating members 40, the number of the driving members 31 is two, and the output shafts 311 of the two driving members 31 are respectively connected to the rotating members 40 at the two ends of the rotating shaft 14. In the power-assisted state, the two driving members 31 synchronously drive the output shafts 311 to jointly output torque to the rotating member 40, and apply a force to the cleaning member 10 through the rotating member 40. In the unlocked state, the two driving members 31 stop outputting torque and allow the two rotating members 40 to rotate freely to release the force applied to the cleaning member 10. Therefore, by setting the two driving members 31, the forces on both sides of the cleaning member 10 can be balanced, and at the same time, a force can be jointly provided to the cleaning member 10, so that the cleaning member 10 has sufficient downward pressure to clean stubborn stains.

[0051] It should be noted that the rotating shaft 14 of the cleaning member 10 and the output shaft 311 of the driving member 31 are not limited to being indirectly connected through an intermediate element. For example, in other embodiments, the output shaft 311 of the cleaning member 10 may also be directly connected to the output shaft 311 of the driving member 31. In this case, the output shaft 311 of the driving member 31 forms a rotating member 40. In the power-assisted state, the output shaft 311 of the driving member 31 directly outputs torque to the cleaning member 10. In the unlocked state, the output shaft 311 of the driving member 31 stops outputting torque and can rotate freely to release the force applied to the cleaning member 10. Thus, the output shaft 311 of the driving member 31 can directly transmit the downward torque to the cleaning member 10, so that the cleaning member 10 increases the friction with the surface 200 to be cleaned.

[0052] Reference Figures 6 to 9 In an optional embodiment, the rotating member 40 includes a convex shaft 41 connected to the rotating shaft 14, and the auxiliary component 20 is provided with a rotating groove 21 adapted to the convex shaft 41, so that the convex shaft 41 can rotate in the rotating groove 21 to drive the cleaning component 10 to rotate; wherein the output shaft 311 of the driving member 31 is fixedly connected to the convex shaft 41, or the output shaft 311 of the driving member 31 forms the convex shaft 41. Exemplarily, the rotating shaft 14 is also the second roller 13. When the output shaft 311 of the driving member 31 is fixedly connected to the convex shaft 41, the convex shaft 41 can be provided at both ends of the second roller 13 along the axial direction, and the rotating grooves 21 that are rotatably matched with the convex shaft 41 can be provided at the corresponding positions on both sides of the auxiliary component 20 and the convex shaft 41, thereby enabling the relative rotation between the cleaning component 10 and the auxiliary component 20. When the output shaft 311 of the driving member 31 forms a convex shaft 41, the output shaft 311 of the driving member 31 is passed through the rotating groove 21 and is directly connected to the rotating shaft 14 of the cleaning component 10, that is, the second roller 13. At this time, the output shaft 311 and the auxiliary component 20 can rotate relative to each other, so that the cleaning component 10 and the auxiliary component 20 can rotate relative to each other.

[0053] It should be noted that when the output shaft 311 of the driving member 31 is connected to the rotating shaft 14 of the cleaning member 10 through the rotating member 40, or the output shaft 311 of the driving member 31 is directly connected to the rotating shaft 14 of the cleaning member 10, Figure 2 and Figure 3 The output shaft 311 needs to be coaxially arranged with the rotating shaft 14 of the cleaning member 10. Of course, the output shaft 311 is not limited to being coaxially arranged with the rotating shaft 14 of the cleaning member 10. Figure 4 and Figure 5 At this time, the driving force of the driving member 31 can be transmitted to the cleaning component 10 through the setting of the connecting member 32, so that the installation position of the driving member 31 can be more flexible.

[0054] Reference Figure 4 In an optional embodiment, the assisting member 30 includes a driving member 31 and a connecting member 32, the connecting member 32 is connected to the output shaft 311 of the driving member 31, and the connecting member 32 is connected to the cleaning member 10; in the assisting state, the driving member 31 is used to drive the connecting member 32 to output a downward torque to the cleaning member 10, so as to increase the force of the cleaning end 10a on the surface to be cleaned 200, or the driving member 31 locks the cleaning member 10 through the connecting member 32 to limit the relative rotation of the cleaning member 10 relative to the auxiliary member 20; in the unlocking state, the output shaft 311 of the driving member 31 stops outputting torque and allows the connecting member 32 to rotate freely, so as to release the force applied by the connecting member 32 to the cleaning member 10. Therefore, through the setting of the connecting member 32, the output torque of the output shaft 311 can be transmitted to the rotating member 40 of the cleaning component 10, so as to act on the cleaning component 10 through the rotating member 40. The connecting member 32 can be a transmission element such as a gear. At this time, the driving member 31 can be installed above or on one side of the cleaning component 10. The output shaft 311 can be parallel or perpendicular to the rotating shaft 14. The output torque can be transmitted to the rotating member 40 through the connecting member 32, so that the installation position of the driving member 31 can be flexibly set.

[0055] Optionally, the number of driving members 31 is not limited to one or two, and three or more driving members 31 may be provided. The output shaft 311 of one or more driving members 31 may output downward torque to the cleaning member 10 , and may also provide downward thrust to the cleaning member 10 .

[0056] Reference Figure 5 In an optional embodiment, the assisting member 30 includes a driving member 31 and a connecting member 32, the connecting member 32 is connected to the output shaft 311 of the driving member 31, and the connecting member 32 is connected to the cleaning member 10; in the assisting state, the driving member 31 is used to provide a downward thrust to the connecting member 32, so as to press down the cleaning member 10, thereby increasing the force of the cleaning end 10a on the surface to be cleaned 200, or the driving member 31 locks the relative rotation of the cleaning member 10 with respect to the auxiliary member 20 through the connecting member 32; in the unlocking state, the driving member 31 is used to release the thrust on the connecting member 32, so as to release the force applied by the connecting member 32 to the cleaning member 10. Thus, the driving member 31 can output a downward thrust to the connecting member 32 through the output shaft 311, so that the connecting member 32 presses down the cleaning member 10. For example, the driving member 31 can use a motor, and convert the driving force into a thrust for linear movement to the connecting member 32 through chain drive, belt drive, screw nut drive, etc. Of course, the driving member 31 can also use a power source such as a cylinder that can directly push the connecting member 32, thereby pressing down the cleaning member 10 to increase the force of the cleaning end 10a on the surface to be cleaned 200. When it is necessary to switch to the unlocked state, the driving member 31 only needs to release the thrust on the connecting member 32.

[0057] In an optional embodiment, the connecting member 32 can press down the cleaning end 10a of the cleaning member 10, thereby directly increasing the friction between the cleaning end 10a and the surface to be cleaned 200. Of course, in other embodiments, the connecting member 32 can also press down the rotating member 40 or the surface of the endless belt 11 at a position corresponding to the rotating shaft 14 (the second roller 13 of the cleaning member 10) (see Figure 5 ) or other positions of the cleaning member 10, so that the cleaning member 10 rotates downward or has a tendency to rotate downward to increase the friction between the cleaning end 10a and the surface 200 to be cleaned.

[0058] In an optional embodiment, the starting position of the connecting member 32 can be in contact with the cleaning component 10 but without any force. When the driving member 31 applies a thrust to the connecting member 32, although the connecting member 32 does not move at this time, the force on the cleaning component 10 is increased, thereby pressing the cleaning component 10 downward, increasing the force of the cleaning end 10a on the surface to be cleaned 200. When the driving member 31 releases the thrust on the connecting member 32, the downward pressure of the connecting member 32 on the cleaning component 10 is also released.

[0059] Of course, in other embodiments, the starting position of the connecting member 32 may also have a gap with the cleaning member 10. When the driving member 31 applies a thrust to the connecting member 32, the connecting member 32 can be driven to move downward to press down the cleaning member 10, so as to increase the force of the cleaning end 10a on the surface to be cleaned 200. When it is necessary to switch to the unlocked state, the driving member 31 can pull the connecting member 32 upward to above the cleaning member 10 to reset to have a gap with the cleaning member 10, thereby releasing the force applied by the connecting member 32 to the cleaning member 10.

[0060] Reference Figures 7 to 11 In an optional embodiment, the auxiliary component 20 includes a conveying portion 22 and an introduction portion 23. The conveying portion 22 forms a conveying slope 221 on a side opposite to the conveying side 111. The conveying slope 221 is at least partially parallel to the conveying side 111. The conveying slope 221 is used to cooperate with the conveying side 111 to assist in conveying garbage. When the cleaning device 100 is working, the garbage conveyed from the cleaning end 10a is clamped between the conveying side 111 and the conveying slope 221, and the garbage is further conveyed to a preset position under the action of friction.

[0061] In an optional embodiment, the introduction part 23 is located on one side of the conveying inclined surface 221 extending toward the surface to be cleaned 200, and the introduction part 23 contacts the surface to be cleaned 200, so as to cooperate with the cleaning member 10 to convey the garbage to the conveying inclined surface 221. When the power-assisting member 30 is in the power-assisting state or the unlocked state, the surface to be cleaned 200 interferes with the introduction part 23. When the cleaning device 100 cleans the surface to be cleaned 200, the introduction part 23 can scrape the garbage on the surface to be cleaned 200 or gather the garbage together during the movement of the cleaning device 100. Since the endless belt 11 of the cleaning member 10 circulates, the cooperation between the endless belt 11 of the cleaning member 10 and the introduction part 23 picks up the garbage and conveys the garbage to between the conveying side 111 and the conveying inclined surface 221. In an optional embodiment, there can also be a small gap between the introduction part 23 and the surface to be cleaned 200, so that the garbage on the surface to be cleaned 200 can be scraped.

[0062] Reference Figures 7 to 9 In an optional embodiment, the cleaning device 100 further includes a recovery container 50, an opening 51 of the recovery container 50 is arranged behind the conveying slope 221 along the forward direction of the cleaning device 100, and the recovery container 50 is used to collect the garbage conveyed through the conveying side 111 and / or the conveying slope 221. Of course, in other embodiments, the cleaning device 100 may not be provided with a recovery container 50. For example, before the cleaning device 100 works, a disposable garbage bag may be fixed on the cleaning device 100, and when the cleaning device 100 works, the garbage conveyed by the cleaning component 10 and the auxiliary component 20 may be collected in the disposable garbage bag.

[0063] Reference Figure 1 In an optional embodiment, the cleaning device 100 further includes a hand-held rod 60 and a chassis 70 rotatably connected to the bottom end of the hand-held rod 60, and the cleaning component 10, the auxiliary component 20, the power-assisting component 30 and the recovery container 50 are all arranged on the chassis 70. Thus, the cleaning device 100 can be a hand-held cleaning device 100, and the power-assisting component 30 is provided to increase the force of the cleaning end 10a on the surface to be cleaned 200, so that the friction force generated by the cleaning end 10a when rubbing the surface to be cleaned 200 is greater, and the stubborn stains on the surface to be cleaned 200 can be cleaned more fully, and the cleaning effect is better.

Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application.
