Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, and in particular to a cutting assembly, a cutting module, a cleaning base station, cleaning equipment and a cleaning system. Background Art

[0002] Cleaning equipment typically includes a roller brush, which is used to clean the surface to be cleaned. When the cleaning device is cleaning the surface to be cleaned, hair or thread-like objects on the surface to be cleaned can easily be caught on the roller brush, affecting the cleaning effect of the roller brush and the normal use of the cleaning device. It may even cause the roller brush to become stuck while cleaning the surface to be cleaned, causing excessive deformation or even breakage, which in turn requires repair or replacement of the roller brush, resulting in increased use and maintenance costs. However, in related art, the entanglement wrapped around the roller brush is usually cut manually, which has low cleaning efficiency, affects the convenience of using the cleaning robot, and reduces the user experience. Alternatively, some related art has a solution that uses a cutting knife to automatically cut the entanglement wrapped around the roller brush, but the effect is not good, the entanglement on the roller brush is not cleaned thoroughly, and the user experience is also poor.

[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0058] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like, indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0059] It should also be understood that the terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in this specification and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0060] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0061] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0062] See also Figure 1 and Figure 2 The embodiment of the present invention provides a cutting assembly 100, which is applied to a cleaning device 2000, wherein the cleaning device 2000 includes a roller brush 2001. The cutting assembly 100 is used to cut at least part of the entanglement on the roller brush 2001.

[0063] Illustratively, the cleaning device 2000 may include at least one of the following:

[0064] Cleaning device 2000 may be an active cleaning device, which is a cleaning device that can autonomously move forward, backward, and turn to reach the surface to be cleaned. This type of active cleaning device has intelligent functions and can automatically adjust its cleaning path based on environmental changes. The appropriateness of the cleaning path depends on the device's intelligence level. Active cleaning devices use built-in sensors, algorithms, and control systems to achieve automatic navigation, obstacle identification, and cleaning path planning, thereby completing cleaning tasks. For example, a sweeping robot uses built-in sensors to perceive the environment and uses a navigation system to plan the optimal cleaning path. It then cleans the floor through functions such as vacuuming, sweeping, and / or mopping. This type of active cleaning device can automatically avoid obstacles and avoid re-cleaning areas that have already been cleaned, thereby improving cleaning efficiency and quality. Active cleaning devices include but are not limited to sweeping robots, vacuuming robots, sweeping and mopping robots, and window cleaning robots. Accordingly, the surface to be cleaned may be the floor, wall, window surface, bed surface, etc.

[0065] Cleaning device 2000 may also be a passive cleaning device, which requires user control to move it to the surface to be cleaned. This type of device typically has a handheld portion, which the user needs to hold and push the roller brush of the cleaning device to move across the surface to be cleaned. Passive cleaning devices include, but are not limited to, handheld floor scrubbers, handheld vacuum cleaners, or handheld mite removers. Accordingly, the surface to be cleaned may be the floor, a wall, a window surface, a bed, or the like.

[0066] The entanglement includes at least one of hair, silk thread, flocculent matter and the like.

[0067] In some embodiments, the cutting assembly 100 can be located on the cleaning base station 1000; when the cleaning device 2000 is placed on the cleaning base station 1000, the cutting assembly 100 can operate and cut at least a portion of the entanglements on the roller brush 2001. When the cleaning device 2000 leaves the cleaning base station 1000, the cutting assembly 100 stops operating. In other embodiments, the cutting assembly 100 can be located on the cleaning device 2000; the cutting assembly 100 can cut at least a portion of the entanglements on the roller brush 2001 during the operation of the cleaning device 2000, thereby preventing the cutting assembly 100 from affecting the normal operation of the cleaning device 2000.

[0068] The following explanation is given by taking the example of the cutting assembly 100 being arranged on the cleaning base station 1000, but the present application is not limited thereto.

[0069] See also Figure 1 and Figure 3 In some embodiments, the cutting assembly 100 includes a base 10 and a cutting member 20, at least a portion of which is connected to the base 10; the cutting member 20 includes a fixed blade 21 and a movable blade 22. The cutting assembly 100 can move in a direction parallel to the axis of the roller brush 2001 under the action of a first external force; at least when the cutting assembly 100 moves within the length of the roller brush 2001, the fixed blade 21 abuts against the roller brush 2001. At least when the cutting assembly 100 moves within the length of the roller brush 2001, the fixed blade 21 can peel at least a portion of the entangled material on the roller brush 2001 from the roller brush 2001, and the movable blade 22 moves relative to the fixed blade 21 so that the movable blade 22 cooperates with the fixed blade 21 to shear the entangled material.

[0070] The cutting assembly 100 of the above embodiment, since the fixed blade 21 abuts against the roller brush 2001 at least during the process of the cutting assembly 100 moving within the length range of the roller brush 2001, the fixed blade 21 can peel off at least part of the entanglements on the roller brush 2001 from the roller brush 2001, and the movable blade 22 moves relative to the fixed blade 21 so that the movable blade 22 cooperates with the fixed blade 21 to shear the entanglements. The fixed blade 21 and the movable blade 22 cooperate to act on the entanglements together, preventing excessive entanglements on the fixed blade 21 from causing jamming, and at the same time improving the cutting efficiency of the cutting assembly 100 in cutting entanglements, which can improve the cleaning efficiency or cleaning effect of the entanglements on the roller brush 2001, and improve the user experience. In addition, under the action of a first external force, the cutting assembly 100 can move in a direction parallel to the axis of the roller brush 2001. At least when the cutting assembly 100 moves to within the length range of the roller brush 2001, the fixed blade 21 abuts against the roller brush 2001. In this way, the cutting assembly 100 can cut the entanglements at different positions in the axial direction of the roller brush 2001, and can ensure the cutting of the entanglements within the entire length direction of the roller brush 2001, which is conducive to more comprehensive cleaning of the entanglements on the roller brush 2001, and can improve the cleaning efficiency or cleaning effect of the entanglements on the roller brush 2001, thereby improving the user experience. Furthermore, at least when the cutting assembly 100 moves within the length of the roller brush 2001, the fixed blade 21 abuts against the roller brush 2001, enabling the fixed blade 21 to both peel at least a portion of the entangled material on the roller brush 2001 from the roller brush 2001 and cooperate with the movable blade 22 to shear the entangled material. This expands the functionality of the fixed blade 21, eliminates the need for two separate structural components to perform these two functions, and reduces the number of components required. This improves the assembly efficiency of the cutting assembly 100, reduces the weight of the cutting assembly 100, and reduces the size of the cutting assembly 100. During the movement of the cutting assembly 100 within the length of the roller brush 2001, the movable blade 22 and the fixed blade 21 perform at least one shearing action or at least two shearing actions.

[0071] For example, after the cutting assembly 100 cuts off the windings, even if the cut windings still remain on the roller brush 2001, the cut windings on the roller brush 2001 can be self-cleaned by the cleaning device 2000. Therefore, by cutting the windings on the roller brush 2001 by the cutting assembly 100, and cooperating with the cleaning device 2000 to clean the cut windings on the roller brush 2001 (such as ordinary dirt), the windings on the roller brush 2001 are automatically cleaned, without the need for manual operation by the user, thereby improving the user experience. The self-cleaning of the cleaning device 2000 means that when the cleaning device 2000 is placed on the cleaning base station 1000, the roller brush 2001 or the cleaning tank where the roller brush 2001 is placed is supplied with water, and the self-cleaning of the roller brush 2001 is achieved by cooperating with the rotation of the roller brush 2001. After the self-cleaning is completed, the dirt in the cleaning tank can be recovered by the recovery device, and the roller brush 2001 can then be dried.

[0072] For example, the axis of the roller brush 2001 is as follows Figure 3 The axis direction of the roller brush 2001 is parallel to Figure 3 The length range of the roller brush 2001 is as follows: Figure 3 As shown in n.

[0073] In some embodiments, at least while the cutting assembly 100 is moving within the length of the roller brush 2001, the movable blade 22 rotates relative to the fixed blade 21 to form a shearing action that shears the entanglement. That is, while the cutting assembly 100 is moving outside the length of the roller brush 2001, the movable blade 22 may rotate relative to the fixed blade 21, or the movable blade 22 may not rotate relative to the fixed blade 21. In other embodiments, at least while the cutting assembly 100 is moving within the length of the roller brush 2001, the movable blade 22 moves linearly relative to the fixed blade 21 to form a shearing action that shears the entanglement.

[0074] See also Figure 4 and Figure 5 In some embodiments, the relative state between the fixed blade 21 and the movable blade 22 has at least an open state (such as Figure 4 as shown) and closed state (as shown Figure 5As shown); the movable blade 22 can reciprocate relative to the fixed blade 21 so that the fixed blade 21 and the movable blade 22 switch between an open state and a closed state to form a shearing action to shear the entanglement. Since the movable blade 22 reciprocates relative to the fixed blade 21 to form a shearing action, it is beneficial to reduce the maximum rotation range of the movable blade 22 while achieving the same cutting effect, thereby reducing the additional work done by the movable blade 22 during movement, which is beneficial to saving power consumption; the reduction in the maximum rotation range of the movable blade 22 can also make the structure of the cutting assembly 100 more compact and the structure of the cutting assembly 100 simple. In other embodiments, the relative state between the fixed blade 21 and the movable blade 22 has at least an open state and a closed state; the movable blade 22 rotates circumferentially relative to the fixed blade 21 so that the fixed blade 21 and the movable blade 22 switch between an open state and a closed state to form a shearing action to shear the entanglement; in this way, the movement mode of the movable blade 22 is simple and easy to control.

[0075] For example, when the relative state between the fixed blade 21 and the movable blade 22 is in the open state, as shown in FIG. Figure 4 When the relative state between the fixed blade 21 and the movable blade 22 is in the closed state, as shown in FIG. Figure 5 shown.

[0076] In some embodiments, see Figure 6 For example, the movable blade 22 is rotatably connected to the fixed blade 21. In this way, while ensuring that the movable blade 22 and the fixed blade 21 can form a shearing action to shear the entangled material, the structure of the cutting assembly 100 can be made more compact. For example, the cutting assembly 100 further includes a connecting shaft 50, which passes through the movable blade 22 and the fixed blade 21. The movable blade 22 is rotatably connected to the fixed blade 21 via the connecting shaft 50.

[0077] In some embodiments, the reciprocating angle of the movable blade 22 relative to the fixed blade 21 is less than 90°. In this way, while ensuring that the cutting assembly 100 can effectively cut the wound material, the maximum rotation range of the movable blade 22 is small, which is conducive to improving cutting efficiency, saving power consumption, and making the structure of the cutting assembly 100 more compact. For example, the reciprocating angle of the movable blade 22 relative to the fixed blade 21 refers to the angle between the movable blade 22 and the fixed blade 21 during the reciprocating rotation of the movable blade 22 relative to the fixed blade 21. Figure 6In some embodiments, the fixed blade 21 includes a hooking end 211; at least when the cutting assembly 100 moves within the length of the roller brush 2001, the hooking end 211 contacts the roller brush 2001, thereby peeling at least a portion of the windings on the roller brush 2001 to the fixed blade 21. When the cutting assembly 100 moves axially along the roller brush 2001, the hooking end 211 can hook the windings on the roller brush 2001 to the fixed blade 21, peeling at least a portion of the windings on the roller brush 2001 to the fixed blade 21. The fixed blade 21 can both peel the windings wrapped around the roller brush 2001 and cooperate with the movable blade 22 to cut the windings. This eliminates the need to provide two separate structures to achieve two functions. The fixed blade 21 has diversified functions, while the cutting assembly 100 has a simple structure.

[0078] See also Figure 3 In some embodiments, the direction parallel to the axis of the roller brush 2001 includes a first direction and a second direction, and the second direction is opposite to the first direction; the hooked end 211 is located in the first direction relative to the fixed blade 21; when the cutting assembly 100 moves only in the first direction, the fixed blade 21 peels off at least part of the windings on the roller brush 2001 from the roller brush 2001. The cutting assembly 100 can only peel off at least part of the windings on the roller brush 2001 from the roller brush 2001 when it moves in one direction, which is conducive to simplifying the structure of the cutting assembly 100, and the structure of the cutting assembly 100 is simple. In other embodiments, when the cutting assembly 100 moves in the first direction, the fixed blade 21 can peel off at least part of the windings on the roller brush 2001 from the roller brush 2001. Exemplarily, the first direction and Figure 3 The positive direction of the X direction is opposite, and the second direction is as follows Figure 3 The positive direction of the X direction (i.e. the direction indicated by the arrow) is shown.

[0079] See also Figure 7 In some embodiments, the fixed blade 21 includes a first guide edge 212, which is connected to the hooked end 211, and the first guide edge 212 faces the roller brush 2001; in the second direction, the distance between the first guide edge 212 and the axis of the roller brush 2001 becomes larger, so that when the cutting assembly 100 moves along the first direction, it is possible to ensure that only the hooked end 211 is in contact with the roller brush 2001, so that the hooked end 211 can effectively peel off the entanglement wrapped around the roller brush 2001, and enable the cutting assembly 100 to cut the entanglement, thereby providing a guarantee for the cutting assembly 100 to effectively clean the entanglement on the roller brush 2001; at the same time, the first guide edge 212 can also play a certain role in avoiding obstacles.

[0080] In some embodiments, when the cutting assembly 10 moves along the roller brush 2001 in both the first and second directions within the length of the roller brush 2001, the cutting assembly 10 can peel off and shear entangled material from the roller brush 2001. Specifically, the cutting assembly 10 may include two axially symmetrically arranged cutting members 20, with the hooking ends 211 of the fixed blades 21 of the two cutting members 20 positioned in the first and second directions relative to the cutting members 20, respectively, so that entangled material from the roller brush can be hooked during the reciprocating motion of the cutting assembly 10 along the roller brush 2001.

[0081] See also Figure 6 and Figure 8 In some embodiments, the cutting assembly 100 further includes an adjusting member 30 , which is respectively connected to the base 10 and the fixed blade 21 , so that the fixed blade 21 moves relative to the base 10 in a preset direction to abut against the roller brush 2001 . The cutting assembly 100 of this embodiment can make the fixed blade 21 abut against the roller brush 2001 even if there is a deviation in the assembly position of the roller brush 2001 when the cleaning device 2000 is assembled, or there is a deviation in the placement position of the roller brush 2001 relative to the base 10, or the diameter of the roller brush 2001 becomes smaller due to aging, or the cutting assembly 100 is used to shear roller brushes 2001 of different specifications, so that the cutting assembly 100 can replace and cut the entangled material; and it is beneficial to reduce or even eliminate the assembly deviation requirements for the roller brush 2001 when assembling the cleaning device 2000, reduce or even eliminate the placement position deviation requirements for the roller brush 2001, extend the service life of the roller brush 2001, and be able to clean roller brushes 2001 of different specifications, thereby expanding the application range of the cutting assembly 100. In addition, when the cutting assembly 100 cleans the entangled objects on the roller brush 2001, since the adjusting member 30 can adjust the position of the fixed blade 21 along the preset direction so that the fixed blade 21 abuts against the roller brush 2001, it can prevent the cutting assembly 100 from rigidly colliding with the roller brush 2001, ensuring that the cutting assembly 100 does not damage the roller brush 2001 during the process of cleaning the entangled objects on the roller brush 2001, thereby improving the user experience.

[0082] Exemplarily, the preset direction is perpendicular to the axis direction of the roller brush 2001. Such a setting can make the force used to move the fixed blade 21 along the preset direction smaller, which is more labor-saving.

[0083] For example, the preset direction is as follows Figure 3 As shown in the Y direction.

[0084] Exemplarily, the adjusting member 30 is an elastic member. When at least part of the cutting member 20 (such as the fixed blade 21) abuts against the roller brush 2001 using the elastic member, the setting of the elastic member can enable at least part of the cutting member 20 (such as the fixed blade 21) to float relative to the roller brush 2001, thereby preventing the abutment force between at least part of the cutting member 20 (such as the fixed blade 21) and the roller brush 2001 from being too large, causing damage to the roller brush 2001 or the cutting assembly 100.

[0085] See also Figure 9 In some embodiments, the fixed blade 21 has an extended position (left) and a retracted position (right) in a predetermined direction; the adjustment member 30 adjusts the movement of the fixed blade 21 between the extended position and the retracted position so that the fixed blade 21 abuts the roller brush 2001. The extended position and the retracted position are the extreme positions of at least a portion of the cutting element 20 in the predetermined direction, and the adjustment member 30 adjusts the movement of at least a portion of the cutting element 20 between the extended position and the retracted position.

[0086] Specifically, the adjustment member 30 may be actively adjusted or passively adjusted:

[0087] The active adjustment method is specifically as follows: the adjusting member 30 can actively adjust the fixed blade 21 to a suitable position corresponding to the demand according to the demand. For example, in some embodiments, when it is necessary to cut the entangled material on the roller brush 2001, if there is still a gap between the fixed blade 21 that needs to abut the roller brush 2001 and the roller brush 2001, the adjusting member 30 can be used to actively adjust the fixed blade 21 to move in a preset direction from the retracted position to the extended position, so that the fixed blade 21 abuts the roller brush 2001, so that the fixed blade 21 can peel off at least part of the entangled material on the roller brush 2001, and the fixed blade 21 and the movable blade 22 can cut the entangled material peeled off to the fixed blade 21, so that the cutting assembly 100 can effectively clean the entangled material on the roller brush 2001. For example, in some embodiments, when there is no need to cut the entangled material on the roller brush 2001 or the fixed blade 21 is in excessive contact with the roller brush 2001, the adjustment member 30 can actively adjust the fixed blade 21 to move in the direction from the extended position to the retracted position to release the contact between the fixed blade 21 and the roller brush 2001, prevent the fixed blade 21 in the extended position or near the extended position from easily injuring the user or prevent excessive contact from causing damage to the roller brush 2001 or the cutting assembly 100, thereby improving the safety of the cutting assembly 100 and facilitating the storage of the cutting assembly 100.

[0088] In the above embodiment, whether the position of the adjusting member 30 needs to be adjusted can be determined by detecting the distance between the fixed blade 21 and the roller brush 2001 or detecting the pressure between the fixed blade 21 and the roller brush 2001; this can be achieved by using distance sensors and / or pressure sensors, etc. These sensors are connected to the controller of the cleaning equipment and / or the cleaning base station and / or the cleaning system, and the adjusting member 30 is controlled by the controller.

[0089] The specific method of passive adjustment is: the adjustment member 30 is floatingly set. If there is no external force, the fixed blade 21 is in the extended position. When there is an external force in the direction from the extended position to the retracted position, the fixed blade 21 moves to the retracted position. For example, in some embodiments, the external force can be provided by the roller brush 2001; when the position of the roller brush 2001 relative to the cutting assembly 100 is between the extended position and the retracted position, the roller brush 2001 will push the fixed blade 21 to move toward the retracted position and make the fixed blade 21 stay in the position abutting the roller brush 2001; and when the position of the roller brush 2001 relative to the cutting assembly 100 becomes larger, the adjusting member 30 will push the fixed blade 21 to move toward the extended position to ensure that the fixed blade 21 abuts the roller brush 2001; when the position of the roller brush 2001 relative to the cutting assembly 100 becomes smaller, the roller brush 2001 will push the fixed blade 21 to continue to move toward the retracted position to avoid excessive abutment between the roller brush 2001 and the fixed blade 21, causing damage to the roller brush 2001 or the cutting assembly 100.

[0090] See also Figure 6 、 8 Exemplarily, the base 10 includes a limiting portion 11, one of the limiting portion 11 and the fixed blade 21 is provided with a long hole 20a, and the other of the limiting portion 11 and the fixed blade 21 is provided with a limiting post 111. The limiting post 111 is provided in the long hole 20a, and the two are slidably arranged along a preset direction; the length direction of the long hole 20a is the same as the preset direction, and the long hole 20a and the limiting post 111 cooperate to limit the fixed blade 21 from moving between the extended position and the retracted position. For example, the limiting portion 11 is provided with the long hole 20a, and the fixed blade 21 is provided with the limiting post 111; or the limiting portion 11 is provided with the limiting post 111, and the fixed blade 21 is provided with the long hole 20a. Through the cooperation between the limiting post 111 and the long hole 20a, the fixed blade 21 can be limited to move along the preset direction, so that the movement of at least part of the cutting member 20 between the extended position and the retracted position is smoother.

[0091] See also Figure 7 and Figure 10In some embodiments, the cleaning device 2000 is placed on the cleaning base station 1000; in the axial direction of the roller brush 2001, there is a first distance d1 between the end of the roller brush 2001 and the cleaning base station 1000, and the length of the first guide edge 212 in the axial direction of the roller brush 2001 is greater than the first distance d1. It should be noted that the roller brush 2001 is usually installed on the cleaning device 2000. In order to achieve the installation of the roller brush 2001, the shell of the cleaning device 2000 needs to provide support for both ends of the roller brush 2001. Therefore, when the cleaning device 2000 is placed on the cleaning base station 1000, the end of the roller brush 2001 must not be close to the cleaning base station 1000. At the same time, in order to facilitate the user to take the cleaning device 2000, there will be a certain gap between the cleaning device 2000 and the cleaning base station 1000. Therefore, there is a first distance d1 between the end of the roller brush and the cleaning base station 1000. The middle of the first distance d1 can be the shell of the cleaning device 2000, the support arm of the roller brush 2001, or the gap between the cleaning device 2000 and the base station 1000. However, when the cutting assembly 100 moves from outside the range of the roller brush to within the range of the roller brush, it needs to cross the first distance d1. If the length of the first guide edge 212 in the axial direction of the roller brush 2001 is set to be less than the first distance 2001, the fixed blade 21 may get stuck in the first distance d1. Therefore, this configuration of the present application also improves the smoothness of the movement of the cutting assembly 100.

[0092] See also Figure 7 In some embodiments, the first guide edge 212 includes a first guide segment 2121 and a second guide segment 2122, wherein the first guide segment 2121 is connected to the second guide segment 2122, the first guide segment 2121 is connected to the hook end 211, and the second guide segment 2122 is away from the hook end 211. Figure 11 In some embodiments, the first guide segment 2121 forms a first acute angle with the second direction. Specifically, the angle α between the first guide segment 2121 and the second direction is an acute angle. This ensures that the fixed blade 21 can effectively remove entanglements from the roller brush 2001 during movement of the cutting assembly 100 in the first direction, thereby simultaneously collecting and cutting the entanglements. Exemplarily, the first acute angle is greater than 0° and less than or equal to 80°. For example, the first acute angle is 10°, 30°, 50°, 60°, 80°, or any suitable value between 0° and 80°. For example, the first acute angle is greater than 0° and less than or equal to 30°.

[0093] See also Figure 11In some embodiments, the second guide segment 2122 forms a first obtuse angle with the first guide segment 2121. That is, the included angle β between the second guide segment 2122 and the first guide segment 2121 is an obtuse angle. This allows the second guide segment 2122 to provide a better guide when encountering an obstacle without causing a jam. This also allows for ample space between the first guide segment 2121 and the second guide segment 2122 to accommodate other structures of the fixed blade 21, such as a structure that cooperates with the adjustment member 30. In some embodiments, the junction between the first guide segment 2121 and the second guide segment 2122 is a first smooth surface or a first curved surface, allowing the cutting assembly 100 to move more smoothly in the second direction.

[0094] See also Figure 7 In some embodiments, the fixed blade 21 includes a first cutting edge 213. The first cutting edge 213 is located on the side of the fixed blade 21 facing away from the roller brush 2001 and is connected to the hook end 211. The first cutting edge 213 includes a first cutting edge 2131 and a first tangent edge 2312. The first cutting edge 2131 is connected to the first tangent edge 2312, which is connected to the hook end 211. The first cutting edge 2131 is located on the side away from the hook end 211. The provision of the first tangent edge 2312 can prevent the area of the first cutting edge 213 near the hook end 211 from injuring the user, thereby improving the safety of the cutting assembly 100. Furthermore, because the first tangent edge 2312 is located at the front end of the first cutting edge 2131 near the hooked end 211, when the fixed blade 21 abuts the roller brush 2001, the first tangent edge 2312 is closer to the roller brush 2001 than the first cutting edge 2131. Therefore, when the movable blade 22 and the fixed blade 21 form a shearing action, the first tangent edge 2312, i.e., the front end of the first cutting edge 2131, does not form a shearing action with the movable blade 22, thereby preventing the cutting assembly 100 from cutting the bristles of the roller brush 2001. It can be understood that the tangent edge has a tangent feel, and the user's fingers will not be cut when touching the tangent edge.

[0095] See also Figure 5 In some embodiments, the movable blade 22 includes a second cutting edge 221; the relative positions of the fixed blade 21 and the movable blade 22 include at least an open state and a closed state. When the fixed blade 21 and the movable blade 22 are in the closed state, the intersection of the first cutting edge 2131 and the second cutting edge 221 is P, and the distance between the intersection P and the first tangent edge 2312 is greater than or equal to 0, thereby providing space for accommodating entanglements peeled from the roller brush 2001. This allows the fixed blade 21 to smoothly peel at least a portion of the entanglements from the roller brush 2001 onto the fixed blade 21 in the closed state.

[0096] See also Figure 5In some embodiments, the fixed blade 21 includes a first cutting edge 2131; the movable blade 22 includes a second cutting edge 221; the relative state of the fixed blade 21 and the movable blade 22 includes at least an open state and a closed state; when the relative state of the fixed blade 21 and the movable blade 22 is in the closed state, the intersection of the first cutting edge 2131 and the second cutting edge 221 is P, and the distance between the intersection P and the hooked end 211 is greater than 0, thereby providing space for accommodating the entanglement peeled off from the roller brush 2001, so that the fixed blade 21 can more smoothly peel off at least part of the entanglement on the roller brush 2001 in the closed state.

[0097] See also Figure 7 In some embodiments, the fixed blade 21 includes a first guide edge 212 and a first cutting edge 213, and the first guide edge 212 and the first cutting edge 213 intersect to form a hooked end 211; the surface of the hooked end 211 is a second smooth surface or a second curved surface, and the second smooth surface or the second curved surface contacts the roller brush 2001, so as to prevent the fixed blade 21 from easily cutting the user and also prevent the fixed blade 21 from easily damaging the roller brush 2001.

[0098] See also Figure 5 , combined with Figure 3 In some embodiments, the fixed blade 21 includes a first cutting edge 2131, and the movable blade 22 includes a second cutting edge 221; the relative state between the fixed blade 21 and the movable blade 22 includes at least an open state and a closed state. During the process of the relative state between the fixed blade 21 and the movable blade 22 changing from the open state to the closed state, the distance between the intersection of the first cutting edge 2131 and the second cutting edge 221 and the axis of the roller brush 2001 is greater than the distance between the hooked end 211 and the axis of the roller brush 2001. This ensures that during the process of the relative state between the fixed blade 21 and the movable blade 22 changing from the open state to the closed state, the hooked end 211 of the fixed blade 21 can abut against the roller brush 2001 to peel at least part of the entangled material on the roller brush 2001. This also prevents the movable blade 22 from contacting the roller brush 2001, which would make it difficult for the fixed blade 21 to peel the entangled material from the roller brush 2001.

[0099] See also Figure 3 、 Figure 4 and Figure 12In some embodiments, the relative state of the fixed blade 21 and the movable blade 22 includes at least an open state and a closed state. When the movable blade 22 and the fixed blade 21 are in the open state, a cutting opening 23 is formed between the fixed blade 21 and the movable blade 22, and the opening 404 of the cutting opening 23 is parallel to the axis of the roller brush 2001. The movable blade 22 includes a protrusion 222, which is used to reduce the opening 404 of the cutting opening 23 to reduce the probability of a user's finger entering the cutting opening and causing a safety accident. The protrusion 222 can have a detent feeling; the protrusion 222 is disposed on the side of the second cutting edge 221 of the movable blade 22 close to the hook end 211; or the protrusion 222 is disposed on the side of the second cutting edge 221 of the movable blade 22 away from the connecting shaft 50. When the fixed blade 21 and the movable blade 22 are in an open state relative to each other, a gap exists between the protrusion 211 and the hook end 211 , so that the winding object can easily enter the cutting opening 23 through the gap. The gap is the opening 404 .

[0100] See also Figure 12 For example, the fixed blade 21 includes a first cutting edge 2131; the movable blade 22 includes a second cutting edge 221; and the relative positions of the fixed blade 21 and the movable blade 22 include at least an open state and a closed state. When the relative positions of the fixed blade 21 and the movable blade 22 are in the open state and / or the closed state, the distance between the intersection of the first cutting edge 2131 and the second cutting edge 221 and the protrusion 222 is greater than or equal to zero. Along the axis of the roller brush 2001, the protrusion 222 and the hook end 211 are located on the same side of the intersection of the first cutting edge 2131 and the second cutting edge 221. With this arrangement, when the movable blade 22 and the fixed blade 21 form a shearing action to shear the entangled material at the cutting opening 23, the protrusion 222 can confine the entangled material within the cutting opening 23 to a certain extent, preventing the entangled material at the cutting opening 23 from escaping from the opening 404 of the cutting opening 23, thereby improving the cutting effect of the entangled material.

[0101] Exemplarily, the movable blade 22 is rotatably connected to the fixed blade 21 via a connecting shaft 50; when the relative state of the fixed blade 21 and the movable blade 22 is a closed state, the intersection of the first cutting edge 2131 and the second cutting edge 221 is located between the protrusion 222 and the connecting shaft 50.

[0102] See also Figure 5 、 Figure 6 and Figure 8In some embodiments, the cutting assembly 100 further includes a transmission member 24 movably connected to the movable blade 22; the transmission member 24 drives the movable blade 22 to move relative to the fixed blade 21 under the action of the second external force. The provision of the transmission member 24 can reduce the size of the movable blade 22 while ensuring that the second external force can drive the movable blade 22 to move relative to the fixed blade 21, thereby increasing flexibility in the design position of the movable blade 22 and making the cutting assembly 100 more compact.

[0103] In some embodiments, the relative states of the fixed blade 21 and the movable blade 22 include at least an open state and a closed state; the position of the transmission member 24 relative to the base 10 includes a first position and a second position. Figure 4 When the movable blade 22 and the fixed blade 21 are in an open state relative to each other, the transmission member 24 is located at a first position relative to the base 10; Figure 5 When the movable blade 22 and the fixed blade 21 are in a closed position relative to each other, the transmission member 24 is located in a second position relative to the base 10. Under the action of a second external force, the transmission member 24 can move between the first position and the second position, thereby switching the state between the fixed blade 21 and the movable blade 22 between the open state and the closed state. For example, the second external force can be applied to the transmission member 24 by the second drive assembly 101 to enable the transmission member 24 to move between the first position and the second position.

[0104] See also Figure 4-6 and Figure 8 In some embodiments, the movable blade 22 is rotationally connected to the fixed blade 21; a first slot 223 is provided on the movable blade 22, and the transmission member 24 is slidably connected to the first slot 223; a second slot 12 is provided on the base 10, and the transmission member 24 is disposed in the second slot 12 and slidably connected relative to the second slot 12. When the transmission member 24 switches between the first position and the second position in the second slot 12, the transmission member 24 slides relative to the first slot 223, and the transmission member 24 slides in the second slot 12 to drive the movable blade 22 to switch between an open state and a closed state relative to the fixed blade 21. The first slot 223 of the movable blade 22 and the transmission member 24 slidably cooperate, and can convert the linear sliding movement of the transmission member 24 into the rotational movement of the movable blade 22. The transmission member 24 slides in cooperation with the second slide groove 12 of the base 10. The second slide groove 12 can limit the movement of the transmission member 24, thereby ensuring that the transmission member 24 can stably drive the movable blade 22 to move, so that the movable blade 22 and the fixed blade 21 form a shearing action.

[0105] See also Figure 8In some embodiments, the base 10 includes a top wall 13 and a bottom wall 14; the cutting assembly 100 also includes a first elastic member 40, one end of the first elastic member 40 is connected to the transmission member 24, and the other end is connected to the top wall 13; when the transmission member 24 is in the first position in the second slide groove 12, the first elastic member 40 is in the first state; when the transmission member 24 is in the second position in the second slide groove 12, the first elastic member 40 is in the second state; the compression degree of the first elastic member 40 in the first state is less than the compression degree in the second state. When the transmission member 24 moves from the first position to the second position under the action of the second external force, it compresses the first elastic member 40, so that the first elastic member 40 changes from the first state to the second state. At this time, the relative state between the fixed blade 21 and the movable blade 22 changes from the open state to the closed state; when the second external force applied to the transmission member 24 is less than the elastic force of the first elastic member 40, for example, when the second external force is removed, the compression degree of the first elastic member 40 is reduced, so that the transmission member 24 can move from the second position toward the first position under the action of the first elastic member 40, thereby switching the relative state between the fixed blade 21 and the movable blade 22 from the closed state to the open state.

[0106] For example, the second drive assembly 101 can drive the transmission member 24 to move from the first position to the second position, thereby changing the relative state between the fixed blade 21 and the movable blade 22 from the open state to the closed state. During the process of the transmission member 24 moving from the first position to the second position, the second drive assembly 101 can compress the first elastic member 40. When the second external force applied by the second drive assembly 101 is removed, the transmission member 24 can move from the second position to the first position under the action of the first elastic member 40, thereby switching the relative state between the fixed blade 21 and the movable blade 22 from the closed state to the open state.

[0107] Exemplarily, the bottom wall of the second sliding groove 12 is a portion of the bottom wall 14 of the base 10 .

[0108] In some embodiments, the first state of the first elastic member 40 is a compressed state. Because elastic members (springs) may differ in length and elastic force, if the elastic member is not pre-compressed in the first state, the first position of the transmission member 24 assembled using different elastic members (springs) may be inconsistent, thereby causing problems with the coordination between the cutting assembly 100 and the remaining structures. Therefore, the first position is set to a compressed state, and the effective travel of the elastic member (spring) is utilized to set the first and second positions of the transmission member 24 within a controllable range to ensure that the movement of the movable blade 22 is within a controllable range. In some embodiments, a second external force acts on the transmission member 24, and the magnitude of the second external force applied to the transmission member 24 in the first position is zero.

[0109] See also Figure 3 and Figure 8 In some embodiments, the direction parallel to the axis of the roller brush 2001 includes a first direction and a second direction, and the second direction is opposite to the first direction. The transmission member 24 includes a contact portion 241, and the contact portion 241 contacts the second external force. In some embodiments, the contact portion 241 includes an arcuate wall 2411, and the second external force contacts the arcuate wall 2411 to drive the transmission member 24 to move; or, the contact portion 241 includes a ball, and the ball rotates relative to the transmission member 24, and the second external force contacts the ball. The contact portion 241 includes an arcuate wall 2411 or a ball, which enables the transmission member 24 to match the structure providing the second external force more smoothly when the cutting assembly 100 moves in a direction parallel to the axis of the roller brush 2001.

[0110] See also Figure 13 and Figure 14In some embodiments, the relative state between the fixed blade 21 and the movable blade 22 includes at least an open state and a closed state; the fixed blade 21 includes a first fixed blade 21a and a second fixed blade 21b; the first fixed blade 21a and the second fixed blade 21b are spaced apart in the circumferential direction of the roller brush 2001. At least during the process of the cutting assembly 100 moving within the length of the roller brush 2001, the first fixed blade 21a and the second fixed blade 21b both contact the roller brush 2001, so that at least a portion of the entangled material on the roller brush 2001 is placed on the first fixed blade 21a and the second fixed blade 21b, so that at least a portion of the entangled material on the roller brush 2001 is peeled off from the roller brush 2001 and transferred to the first fixed blade 21a and / or the second fixed blade 21b, so that the fixed blade 21 and the movable blade 22 cooperate to shear the entangled material. The movable blade 22 includes a rotating blade, at least part of which can rotate between the first fixed blade 21a and the second fixed blade 21b, so that the fixed blade 21 and the movable blade 22 can switch between an open state and a closed state to form a shearing action to shear the winding; when shearing the winding, the first fixed blade 21a and the second fixed blade 21b can play a certain supporting role on the winding, which is conducive to cutting the winding more easily and improving the shearing effect of the cutting assembly 100 in shearing the winding; it can also avoid as much as possible the problem of the winding being stretched or deformed when shearing the winding, thereby affecting the shearing efficiency, thereby improving the cleaning efficiency or cleaning effect of the winding. It can be understood that during the movement of the cutting assembly 100 within the length range of the roller brush 2001, the first fixed blade 21a and the second fixed blade 21b are in contact with the roller brush 2001, and the movable blade 22 can be rotated to between the first fixed blade 21a and the second fixed blade 21b. In this way, the first fixed blade 21a and the second fixed blade 21b can both hook up or peel off the entanglements on the roller brush 2001, which is beneficial to improve the shearing effect of the cutting assembly 100 in shearing the entanglements on the roller brush 2001. The movable blade 22 includes a rotating blade, which can rotate back and forth or rotate in a circle relative to the first fixed blade 21a and the second fixed blade 21b, so that the fixed blade 21 and the movable blade 22 can switch between an open state and a closed state to form a shearing action to shear the entanglements. Exemplarily, the rotation axis of the rotating blade is as shown in FIG. Figure 14 As shown by the dotted line h in .

[0111] See also Figure 15 The embodiment of the present application also provides a cutting module 100a, including a cutting assembly 100, a first drive assembly 200 and a second drive assembly 101, the cutting assembly 100 including the cutting assembly 100 of any one embodiment of the present application; the first drive assembly 200 is used to provide a first external force to make the cutting assembly 100 reciprocate along a direction parallel to the axis of the roller brush 2001; the second drive assembly 101 is used to provide a second external force to make the movable blade 22 move relative to the fixed blade 21.

[0112] The cutting module 100a of the above embodiment, since the fixed blade 21 abuts against the roller brush 2001 at least during the process of the cutting component 100 moving within the length range of the roller brush 2001, the fixed blade 21 can peel off at least part of the entanglements on the roller brush 2001 from the roller brush 2001, and the movable blade 22 moves relative to the fixed blade 21 so that the movable blade 22 cooperates with the fixed blade 21 to shear the entanglements. The movable blade 22 and the fixed blade 21 cooperate to act on the entanglements together, preventing the fixed blade 21 from getting stuck due to excessive entanglements, and at the same time improving the cutting efficiency of the cutting component 100 in cutting the entanglements, which can improve the cleaning efficiency or cleaning effect of the entanglements on the roller brush 2001, and improve the user experience. In addition, under the action of a first external force, the cutting assembly 100 can move in a direction parallel to the axis of the roller brush 2001. At least when the cutting assembly 100 moves to within the length range of the roller brush 2001, the fixed blade 21 abuts against the roller brush 2001. In this way, the cutting assembly 100 can cut the entanglements at different positions in the axial direction of the roller brush 2001, and can ensure the cutting of the entanglements within the entire length direction of the roller brush 2001, which is conducive to more comprehensive cleaning of the entanglements on the roller brush 2001, and can improve the cleaning efficiency or cleaning effect of the entanglements on the roller brush 2001, thereby improving the user experience. Furthermore, at least when the cutting assembly 100 moves within the length of the roller brush 2001, the fixed blade 21 abuts against the roller brush 2001, enabling the fixed blade 21 to both peel at least a portion of the entangled material on the roller brush 2001 from the roller brush 2001 and cooperate with the movable blade 22 to shear the entangled material. This expands the functionality of the fixed blade 21, eliminates the need for two separate structural components to perform these two functions, and reduces the number of components required. This improves the assembly efficiency of the cutting assembly 100, reduces the weight of the cutting assembly 100, and reduces the size of the cutting assembly 100. During the movement of the cutting assembly 100 within the length of the roller brush 2001, the movable blade 22 and the fixed blade 21 perform at least one shearing action or at least two shearing actions.

[0113] See also Figure 15 In some embodiments, the first drive assembly 200 includes a drive motor 201, which can drive the cutting assembly 100 to reciprocate in a direction parallel to the axis of the roller brush 2001. The drive motor 201 can automatically control the reciprocating movement of the cutting assembly 100 in a direction parallel to the axis of the roller brush 2001 without manual operation by the user, thereby improving user convenience and user experience.

[0114] Exemplarily, the drive motor 201 can drive the cutting assembly 100 to reciprocate between a starting position and an ending position along a direction parallel to the axis of the roller brush 2001. For example, the drive motor 201 can drive the cutting assembly 100 to move from the starting position to the ending position along a first direction; when the cutting assembly 100 moves to the ending position, the cutting assembly 100 triggers a limit switch or the cutting module 100a detects that the current of the drive motor 201 is greater than or equal to a first preset threshold value, at which point the cutting module 100a controls the drive motor 201 to reverse, and the movement direction of the cutting assembly 100 changes from the first direction to the second direction; when the cutting assembly 100 moves from the ending position to the starting position along the second direction, the cutting assembly 100 triggers another limit switch or the cutting module 100a detects that the current of the drive motor 201 is greater than or equal to a second preset threshold value, at which point the cutting module 100a controls the drive motor 201 to stop working. The first preset threshold value and the second preset threshold value may be the same or different.

[0115] See also Figure 15 In some embodiments, the first drive assembly 200 includes a drive motor 201 and a transmission structure 202. The drive motor 201 is in transmission connection with the cutting assembly 100 via the transmission structure 202. Exemplarily, the transmission structure 202 includes at least one of the following: a screw structure, a pull rope mechanism, a synchronous belt structure, etc. Exemplarily, the transmission structure 202 includes a screw 2021, with the drive motor 201 in transmission connection with the screw 2021, and the base 10 of the cutting assembly 100 is in sliding connection with the screw 2021.

[0116] See also Figure 16 and Figure 17 In some embodiments, the second drive assembly 101 includes a guide member 1011, which is arranged parallel to the axis of the roller brush 2001. During the reciprocating motion of the cutting assembly 100 parallel to the axis of the roller brush 2001, the guide member 1011 is used to drive the movable blade 22 to rotate back and forth relative to the fixed blade 21. This configuration simplifies the structure of the second drive assembly 101. For example, during the reciprocating motion of the cutting assembly 100 parallel to the axis of the roller brush 2001, the guide member 1011 and the first elastic member 40 jointly drive the movable blade 22 to rotate back and forth relative to the fixed blade 21.

[0117] See also Figure 16 and Figure 17In some embodiments, the guide member 1011 includes at least one peak section 10111 and at least one trough section 10112, with the peak sections 10111 and trough sections 10112 alternately connected; the peak sections 10111 are closer to the roller brush 2001 than the trough sections 10112. When the cutting assembly 100 moves to the peak section 10111, the movable blade 22 is in a closed state relative to the fixed blade 21; when the cutting assembly 100 moves to the trough section 10112, the movable blade 22 is in an open state relative to the fixed blade 21. This structure of the second drive assembly 101 eliminates the need for the user to manually operate the movable blade 22 to reciprocate relative to the fixed blade 21, freeing the user's hands and facilitating automatic cutting of entangled materials, thereby improving ease of use and user experience. It also eliminates the need for a motor drive, saving power consumption and simplifying the structure of the second drive assembly 101.

[0118] In other embodiments, the second driving assembly 101 may also include a motor, but the present application is not limited thereto.

[0119] See also Figure 4 、 Figure 5 and Figure 17 In some embodiments, the cutting assembly 100 further includes a transmission member 24, which is movably connected to the movable blade 22. The position of the transmission member 24 relative to the base 10 includes a first position and a second position. The relative states of the fixed blade 21 and the movable blade 22 include at least an open state and a closed state. When the cutting assembly 100 moves to the peak section 10111, the peak section 10111 abuts the transmission member 24, causing the transmission member 24 to be in the second position and the movable blade 22 to be in a closed state relative to the fixed blade 21. When the cutting assembly 100 moves to the trough section 10112, the trough section 10112 abuts or does not contact the transmission member 24, causing the transmission member 24 to be in the first position and the movable blade 22 to be in an open state relative to the fixed blade 21. In this way, the transmission member 24 cooperates with the guide member 1011 to switch the relative state between the fixed blade 21 and the movable blade 22 between an open state and a closed state, thereby forming a shear winding. The cutting module 100a has a simple structure.

[0120] See also Figure 17 In some embodiments, the trough section 10112 is a plane. When the cutting assembly 100 moves to the trough section 10112, the planar trough section 10112 can make the cooperation between the transmission member 24 and the guide member 1011 smoother, and can make the cutting assembly 100 move more smoothly in a direction parallel to the axis of the roller brush 2001.

[0121] See also Figure 16 and Figure 17In some embodiments, in the axial direction of the roller brush 2001, the length of the trough section 10112 is greater than the length of the peak section 10111. This allows the transmission member 24 to be in the first position for a longer period than the second position, and the movable blade 22 to move longer when in an open position relative to the fixed blade 21 than when in a closed position. Consequently, when the cutting assembly 100 moves to the trough section 10112, the fixed blade 21 has more time to peel more entangled material from the roller brush 2001 to the cutting opening 23. Furthermore, when the cutting assembly 100 moves to the peak section 10111, the cutting assembly 100 can efficiently and quickly cut off the entangled material, thereby ensuring that the cutting assembly 100 can pick up as much entangled material as possible within the length of the roller brush 2001.

[0122] See also Figure 3 and Figure 16 In some embodiments, the direction parallel to the axis of the roller brush 2001 includes a first direction and a second direction, the second direction being opposite to the first direction. When the cutting assembly 100 moves only in the first direction, the fixed blade 21 peels at least a portion of the entangled material on the roller brush 2001 from the roller brush 2001. The roller brush 2001 has a starting end and an ending end in the first direction. The trough section 10112 is disposed corresponding to the starting end, and / or the peak section 10111 is disposed corresponding to the ending end.

[0123] See also Figure 17 and Figure 18 In some embodiments, the cutting module 100a includes an upper cover 102, which is disposed above the cutting assembly 100. A guide member 1011 is disposed on the upper cover 102 and below the upper cover 102. This arrangement ensures that the guide member 1011 can drive the transmission member 24 to move while preventing dirt from accumulating on the guide member 1011 and affecting the shearing movement of the cutting assembly 100.

[0124] See also Figure 18 In some embodiments, the cutting module 100a includes a display assembly 103, which is disposed above the upper cover 102. The upper cover 102 is disposed above the cutting assembly 100, and the display assembly 103 is disposed above the upper cover 102. The upper cover 102 can separate the display assembly 103 and the cutting assembly 100, preventing the movement of at least part of the cutting assembly 100 from interfering with the display assembly 103. In addition, the guide member 1011 is located below the upper cover 102, and the display assembly 103 is disposed above the upper cover 102, which can fully utilize the space. The display assembly 103 is used to display at least one of the following: the operating parameters of the cleaning base station 1000, the operating parameters of the cutting module 100a, or the cleaning mode of the cleaning base station or the cleaning device.

[0125] See also Figure 19 The embodiment of the present application also provides a cleaning base station 1000, which is at least used to cut at least part of the entanglement of the roller brush 2001 of the cleaning device 2000. The cleaning base station 1000 includes the cutting component 100 of any one of the above embodiments or the cutting module 100a of any one of the above embodiments.

[0126] In the cleaning base station 1000 of the above embodiment, since the fixed blade 21 abuts against the roller brush 2001 at least during the process of the cutting component 100 moving within the length range of the roller brush 2001, the fixed blade 21 can peel off at least part of the entanglements on the roller brush 2001 from the roller brush 2001, and the movable blade 22 moves relative to the fixed blade 21 so that the movable blade 22 cooperates with the fixed blade 21 to shear the entanglements. The fixed blade 21 and the movable blade 22 cooperate to act on the entanglements, preventing the fixed blade 21 from getting stuck due to excessive entanglements, and at the same time improving the cutting efficiency of the cutting component 100 in cutting the entanglements, which can improve the cleaning efficiency or cleaning effect of the entanglements on the roller brush 2001 and improve the user experience. In addition, under the action of a first external force, the cutting assembly 100 can move in a direction parallel to the axis of the roller brush 2001. At least when the cutting assembly 100 moves to within the length range of the roller brush 2001, the fixed blade 21 abuts against the roller brush 2001. In this way, the cutting assembly 100 can cut the entanglements at different positions in the axial direction of the roller brush 2001, and can ensure the cutting of the entanglements within the entire length direction of the roller brush 2001, which is conducive to more comprehensive cleaning of the entanglements on the roller brush 2001, and can improve the cleaning efficiency or cleaning effect of the entanglements on the roller brush 2001, thereby improving the user experience. Furthermore, at least when the cutting assembly 100 moves within the length of the roller brush 2001, the fixed blade 21 abuts against the roller brush 2001, enabling the fixed blade 21 to both peel at least a portion of the entangled material on the roller brush 2001 from the roller brush 2001 and cooperate with the movable blade 22 to shear the entangled material. This expands the functionality of the fixed blade 21, eliminates the need for two separate structural components to perform these two functions, and reduces the number of components required. This improves the assembly efficiency of the cutting assembly 100, reduces the weight of the cutting assembly 100, and reduces the size of the cutting assembly 100. During the movement of the cutting assembly 100 within the length of the roller brush 2001, the movable blade 22 and the fixed blade 21 perform at least one shearing action or at least two shearing actions.

[0127] See also Figures 18 to 20In some embodiments, the cleaning base station 1000 includes a housing 400, which defines an inner cavity 401 and an outer cleaning chamber 402. The cleaning chamber 402 is used to house the roller brush 2001 and has an opening for the roller brush 2001 to enter. A chute 403 is provided in the wall of the cleaning chamber 402, connecting the inner cavity 401 and the cleaning chamber 402. The chute 403 corresponds to the roller brush 2001. The cutting assembly 100 or a portion of the cutting module 100a is disposed in the inner cavity 401, and at least a portion of the cutting element 20 extends out of the inner cavity 401 through the chute 403 to cut at least a portion of the material wrapped around the roller brush 2001. This configuration provides a compact structure for the cleaning base station 1000.

[0128] It can be understood that the cleaning chamber 402 is the area within the cleaning base station 1000 for placing the roller brush 2001 of the cleaning device 2000. The roller brush 2001 can perform self-cleaning in this area. When the roller brush 2001 of the cleaning device 2000 is placed in the cleaning chamber 402, the cleaning base station 1000 can perform maintenance on the roller brush 2001. This maintenance includes but is not limited to at least one of the following: controlling the cutting assembly 100 or the cutting module 100a to cut at least a portion of the entangled material on the roller brush 2001; spraying water for cleaning, spraying cleaning fluid, etc.

[0129] It should be noted that the corresponding arrangement of the chute 403 and the roller brush 2001 means that the position of the chute 403 is set so that the cutting assembly 100 or the cutting module 100a can at least contact the roller brush 2001 after passing through the chute 403. In some embodiments, the chute 403 is located in front of the roller brush 2001. In this case, the cutting assembly 100 or the cutting module 100a passing through the chute 403 is also located in front of the roller brush 2001. In other embodiments, in the height direction, the slide groove 403 is located below the axis of the roller brush 2001 (not more than 1 cm) or roughly flush with the axis of the roller brush 2001; at this time, the cutting assembly 100 or the cutting module 100a is also located in the front and below the axis of the roller brush 2001 (not more than 1 cm), or the cutting assembly 100 or the cutting module 100a is also located at a position roughly flush with the axial direction of the roller brush 2001 to facilitate maintenance of the roller brush 2001. That is to say, the cutting assembly 100 or the cutting module 100a is located in front of the cleaning chamber 402, or the inner chamber 401 is located in front of the cleaning chamber 402, or the cutting assembly 100, the cutting module 100a, and the inner chamber 401 are all located in front of the cleaning chamber 402; so that after the cleaning equipment 2000 is placed in the cleaning chamber 402, the roller brush 2001 and the slide groove 403 are arranged correspondingly, and at the same time, the cutting assembly 100 or the cutting module 100a can maintain the roller brush 2001.

[0130] See also Figure 19 and Figure 20 In some embodiments, the cleaning base station 1000 includes a first seal 501 connected to the base 10. A first external force is used to drive the cutting assembly 100 and at least a portion of the first seal 501 to move along the slide groove 403. During the movement of the cutting assembly 100 and at least a portion of the first seal 501 along the slide groove 403, the first seal 501 at least partially closes the slide groove 403 to separate the cleaning cavity 402 from the inner cavity 401. When the cleaning device 2000 is placed into the cleaning base station 1000 through the base station entrance of the cleaning base station 1000, the roller brush 2001 of the cleaning device 2000 is located in the cleaning cavity 402, and the cleaning device 2000 can perform self-cleaning in the cleaning cavity 402. As the cutting assembly 100 moves along the chute 403, the first sealing member 501, driven by a first external force, moves along the chute 403 along with the cutting assembly 100, at least partially closing the chute 403 to separate the cleaning chamber 402 from the inner chamber 401, thereby dynamically separating the cleaning chamber 402 from the inner chamber 401. This isolates dirt from the roller brush 2001, or dirt generated during self-cleaning of the cleaning chamber 402, outside the housing 400 and within the cleaning chamber 402, thereby reducing the probability of dirt entering the inner chamber 401 through the chute 403 and thus preventing it from affecting the normal operation of the various mechanisms within the inner chamber 401. This ensures the operational stability of the cleaning base station 1000 and extends the service life of the cleaning base station 1000. When the cutting assembly 100 is stopped, the first sealing member 501 still maintains the separation between the cleaning chamber 402 and the inner chamber 401, thereby enabling the chute 403 to separate the cleaning chamber 402 from the inner chamber 401 in all states.

[0131] Exemplarily, the first seal 501 closes the slide groove 403 in two situations: First, it may refer to the first seal 501 completely sealing the slide groove 403. In this case, the dirt, especially the liquid, in the cleaning chamber 402 will not enter the inner chamber 401, thereby achieving a good sealing effect; Second, it may also refer to a very small gap between the first seal 501 and the slide groove 403, so as to facilitate the first seal 501 to slide on the slide groove 403, prevent excessive friction from being generated, and affect the sliding of the first seal 501 (which will also affect the performance of the first drive component 200 or cause the first seal 501 to deform in the long run). In this case, most of the dirt, especially the liquid, in the cleaning chamber 402 will be isolated outside the shell 400, and the probability of dirt entering the inner chamber 401 will be greatly reduced. Even if dirt (such as liquid) enters the inner chamber 401, the amount will not be too large and will not affect the normal operation of the components in the shell 400.

[0132] See also Figure 10 or Figure 20In some embodiments, the housing 400 further includes a first accommodating space 301, which is located outside the length range of the chute 403 and communicates with the inner cavity 401. The cutting assembly 100 moves along the chute 403 and enters the first accommodating space 301. The first accommodating space 301 is used to park the cutting assembly 100. In this way, it can ensure that at least part of the cutting assembly 100 can move into the first accommodating space 301, realizing the storage of the cutting assembly 100, facilitating the placement of the cleaning device 2000 into the cleaning base station 1000, preventing the cutting assembly 100 from accidentally injuring the cleaning device 2000 or the user, and improving the safety of the cutting assembly 100 when it is not necessary to cut windings. It can also ensure that the cutting assembly 100 can extend into the cleaning cavity 402, so that the cutting assembly 100 can peel off and cut windings on the roller brush 2001. The structure of the cleaning base station 1000 is simple.

[0133] See also Figure 10 For example, a first pre-pressing portion 302 is provided in the first accommodating space 301; when the cutting assembly 100 is located in the first accommodating space 301, the first pre-pressing portion 302 pre-presses the cutting assembly 100 (for example, pre-presses the fixed blade 21), so that the position of the cutting assembly 100 is outside the extension line of the surface of the roller brush 2001. At this time, the cutting assembly 100 is in a non-extended position, that is, the cutting assembly 100 can be pre-pressed to the retracted position or to a position between the retracted position and the extended position, and a second distance d2 is provided between the cutting assembly 100 and the extension line of the surface of the roller brush 2001. In this way, when the cutting assembly 100 moves from the starting position to the end position along the first direction, the hooked end 211 of the fixed blade 21 can be prevented from colliding with the end of the roller brush 2001, thereby ensuring that the cutting assembly 100 can move more smoothly from the starting position to the end position along the first direction. At the same time, in some embodiments, when the cleaning device 2000 is placed on the cleaning base station 1000, there is a first distance d1 between the end of the roller brush and the cleaning base station 1000 in the axial direction of the roller brush, and the length of the first guide edge 212 in the axial direction of the roller brush is greater than the first distance d1. Thus, the cutting assembly 100 can cross the first distance d1 in a pre-pressed state to prevent jamming when crossing the first distance d1. At this time, the distance between the support arm of the roller brush or the outer shell of the cleaning device 2000 and the axis of the roller brush is less than the distance between the cutting assembly 100 and the axis of the roller brush when it is in the pre-pressing portion 302.

[0134] See also Figure 20In some embodiments, the housing 400 includes an opening 404, which communicates with one end of the chute 403 and the first accommodating space 301 and the clean chamber 402. At least a portion of the cutting assembly 100 in the clean chamber 402 moves along the chute 403 and enters the first accommodating space 301 through the opening 404. The provision of the opening 404 ensures that at least a portion of the cutting assembly 100 can enter or exit the first accommodating space 301.

[0135] See also Figure 19 and Figure 20 In some embodiments, the cleaning base station 1000 further includes a second sealing member 502, which is used to seal the opening 404 to separate the cleaning chamber 402 from the first receiving space 301. As the cutting assembly 100 moves along the slide 403, the force of the cutting assembly 100 advancing can cause the position or state of the second sealing member 502 to change, thereby opening the opening 404, allowing the cutting assembly 100 to enter or exit the first receiving space 301 through the opening 404. When the cutting assembly 100 moves along the slide groove 403 to the opening 404, the second seal 502 provided at the opening 404 contacts the cutting assembly 100, so that the second seal 502 can clean at least part of the dirt of the cutting assembly 100 while facilitating the cutting assembly 100 to enter and exit the first accommodating space 301. The second seal 502 can not only realize the function of closing the opening 404 to prevent dirt (such as dust or cut-off windings, etc.) from easily entering the first accommodating space 301 during the self-cleaning process of the cleaning device 2000 and affecting the normal operation of the structural parts in the first accommodating space 301; the second seal 502 can also clean at least part of the cutting assembly 100 to prevent dirt (such as dust or cut-off windings, etc.) from easily remaining in the cutting assembly 100, thereby diversifying the functions of the second seal 502.

[0136] See also Figure 15 and Figure 18 Exemplarily, the cutting module 100a further includes a lower cover 104. The upper cover 102 and the lower cover 104 are disposed in the inner cavity 401 of the housing 400. The upper cover 102 is connected to the lower cover 104. The first drive assembly 200 is at least partially disposed in at least one of the upper cover 102 and the lower cover 104. Exemplarily, the upper cover 102 and the lower cover 104 are part of the housing 400.

[0137] See also Figure 1 and Figure 2 、 Figure 21, an embodiment of the present application further provides a cleaning device 2000, including a roller brush 2001; and, a cutting assembly 100 of any embodiment of the present application or a cutting module 100a of any embodiment of the present application.

[0138] The cleaning device 2000 of the above embodiment, since the fixed blade 21 abuts against the roller brush 2001 at least during the process of the cutting component 100 moving within the length range of the roller brush 2001, the fixed blade 21 can peel off at least part of the entanglements on the roller brush 2001 from the roller brush 2001, and the movable blade 22 moves relative to the fixed blade 21 so that the movable blade 22 cooperates with the fixed blade 21 to shear the entanglements. The fixed blade 21 and the movable blade 22 cooperate to act on the entanglements, preventing the fixed blade 21 from getting stuck due to excessive entanglements, and at the same time improving the cutting efficiency of the cutting component 100 in cutting the entanglements, which can improve the cleaning efficiency or cleaning effect of the entanglements on the roller brush 2001 and improve the user experience. In addition, under the action of a first external force, the cutting assembly 100 can move in a direction parallel to the axis of the roller brush 2001. At least when the cutting assembly 100 moves to within the length range of the roller brush 2001, the fixed blade 21 abuts against the roller brush 2001. In this way, the cutting assembly 100 can cut the entanglements at different positions in the axial direction of the roller brush 2001, and can ensure the cutting of the entanglements within the entire length direction of the roller brush 2001, which is conducive to more comprehensive cleaning of the entanglements on the roller brush 2001, and can improve the cleaning efficiency or cleaning effect of the entanglements on the roller brush 2001, thereby improving the user experience. In addition, at least when the cutting assembly 100 moves to within the length range of the roller brush 2001, the fixed blade 21 abuts against the roller brush 2001, so that the fixed blade 21 can both peel off at least part of the entangled material on the roller brush 2001 from the roller brush 2001, and cooperate with the movable blade 22 to shear the entangled material, thereby expanding the function of the fixed blade 21. There is no need to set up two independent structural components for the two functions separately, saving the number of components set up, which is beneficial to improving the assembly efficiency of the cutting assembly 100, reducing the weight of the cutting assembly 100, and reducing the volume of the cutting assembly 100.

[0139] Illustratively, the roller brush 2001 includes the roller brush 2001 of any one of the above embodiments.

[0140] See also Figure 2 The embodiment of the present application further provides a cleaning system, including a cleaning device 2000 and a cleaning base station 1000. The cleaning base station 1000 includes a docking position, and the cleaning device 2000 can be docked at the docking position.

[0141] In the cleaning system of the above embodiment, since the fixed blade 21 abuts against the roller brush 2001 at least during the process of the cutting assembly 100 moving within the length range of the roller brush 2001, the fixed blade 21 can peel off at least part of the entanglements on the roller brush 2001 from the roller brush 2001, and the movable blade 22 moves relative to the fixed blade 21 so that the movable blade 22 cooperates with the fixed blade 21 to shear the entanglements. The fixed blade 21 and the movable blade 22 cooperate to act on the entanglements, preventing the fixed blade 21 from getting stuck due to excessive entanglements, and at the same time improving the cutting efficiency of the cutting assembly 100 in cutting the entanglements, which can improve the cleaning efficiency or cleaning effect of the entanglements on the roller brush 2001 and improve the user experience. In addition, under the action of a first external force, the cutting assembly 100 can move in a direction parallel to the axis of the roller brush 2001. At least when the cutting assembly 100 moves to within the length range of the roller brush 2001, the fixed blade 21 abuts against the roller brush 2001. In this way, the cutting assembly 100 can cut the entanglements at different positions in the axial direction of the roller brush 2001, and can ensure the cutting of the entanglements within the entire length direction of the roller brush 2001, which is conducive to more comprehensive cleaning of the entanglements on the roller brush 2001, and can improve the cleaning efficiency or cleaning effect of the entanglements on the roller brush 2001, thereby improving the user experience. Furthermore, at least when the cutting assembly 100 moves within the length of the roller brush 2001, the fixed blade 21 abuts against the roller brush 2001, enabling the fixed blade 21 to both peel at least a portion of the entangled material on the roller brush 2001 from the roller brush 2001 and cooperate with the movable blade 22 to shear the entangled material. This expands the functionality of the fixed blade 21, eliminates the need for two separate structural components to perform these two functions, and reduces the number of components required. This improves the assembly efficiency of the cutting assembly 100, reduces the weight of the cutting assembly 100, and reduces the size of the cutting assembly 100. During the movement of the cutting assembly 100 within the length of the roller brush 2001, the movable blade 22 and the fixed blade 21 perform at least one shearing action or at least two shearing actions.

[0142] Illustratively, the cleaning device 2000 includes the cleaning device 2000 of any one of the above embodiments. Illustratively, the cleaning base station 1000 includes the cleaning base station 1000 of any one of the above embodiments.
