[0030] With the advancement of technology, cleaning equipment has become increasingly popular, gradually replacing floor cleaning tasks in homes and offices. Most cleaning equipment uses a cleaning roller brush to clean the floor. During the cleaning process, hair and other linear objects on the floor can easily become entangled in the outer circumference of the cleaning roller brush. If there are too many entangled objects, this can affect the cleaning function at best, or even cause the cleaning roller brush to clog and damage the machine.

[0031] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present application and are not to be construed as limiting the present application.

[0032] Based on the above considerations, the present application proposes a cleaning roller brush, a cleaning device and a cleaning system to cut and clean entanglements, reduce operating resistance, ensure cutting effect, and improve the durability of the device.

[0033] The cleaning roller brush provided in the embodiments of the present application is installed on a cleaning device and is primarily used to clean objects to be cleaned. The cleaning roller brush provided in the embodiments of the present application can automatically remove objects entangled in the cleaning roller brush during the cleaning process, reducing the impact of these objects on the cleaning roller brush and its operation, thereby improving the cleaning performance and service life of the cleaning roller brush. The following describes various embodiments of the cleaning roller brush described in the present application with reference to various figures.

[0034] Figure 1 This is a schematic diagram of the structure of the cleaning roller brush 100 provided in one embodiment of the present application. Figure 1 The cleaning roller brush 100 includes a housing 110, a cleaning unit, at least two first cutting members 120, and a second cutting member 130. The cleaning unit is mounted on the housing 110; the at least two first cutting members 120 are fixedly mounted at different positions on the housing 110; and the second cutting member 130 is movably mounted on the housing 110. The second cutting member 130 moves back and forth between the at least two first cutting members 120 and cooperates with the corresponding first cutting member 120 to cut when it moves to a corresponding position.

[0035] The roughly cylindrical housing 110 provides a mounting base for the cleaning unit, first cutting element 120, and second cutting element 130. Housing 110 is connected to a drive mechanism for the cleaning device, allowing it to rotate relative to the main body of the cleaning device. The cleaning unit is mounted on the outer periphery of housing 110 and is primarily designed to contact and clean the floor during the rotation of the roller brush 100.

[0036] For ease of explanation, the extension direction of the housing 110, i.e., the axial direction of the housing 110, is referred to as the X-direction, and the radial direction of the housing 110 is referred to as the Y-direction. The cleaning portion may be in the form of an elongated strip and arranged along the X-direction. For example, the cleaning portion may be arranged in a straight line in the X-direction, or in an arc in the X-direction, or may be arranged in a spiral shape in the extension direction of the housing 110. The specific arrangement is not limited thereto. Furthermore, there may be multiple cleaning portions, with the multiple cleaning portions spaced apart around the outer circumference of the housing 110, and the shapes of any two cleaning portions may be the same or different.

[0037] As the cleaning device drives the cleaning roller brush 100 to rotate, hair and other linear entanglements may become entangled around the outer circumference of the housing 110 as the housing 110 rotates. Providing at least two first cutting members 120 at different locations on the housing 110 allows for processing entanglements at different locations on the housing 110, resulting in a better effect in cutting the entanglements. The number of first cutting members 120 is not specifically limited and may be two or more.

[0038] The second cutting member 130 is movably mounted on the housing 110. The second cutting member 130 reciprocates between at least two first cutting members 120 and, when moved to a corresponding position, cooperates with the corresponding first cutting member 120 for cutting. Specifically, the first cutting member 120 is relatively fixed relative to the housing 110. By arranging the second cutting member 130 to reciprocate between at least two first cutting members 120, the second cutting member 130 cooperates with one of the first cutting members 120 for cutting, or cooperates with another second cutting member for cutting. The reciprocating motion arrangement allows for multiple cuts, ensuring efficient cutting of the windings, and allowing cutting of windings at different positions.

[0039] Specifically, see Figure 2 and Figure 3 , Figure 2 yes Figure 1 The cross-sectional view at AA in the middle, Figure 3 This is a cross-sectional view of another state of the cleaning roller brush 100 provided in one embodiment of the present application. Figure 2 and Figure 3 The Y direction is the up-down direction. For example, the first cutting member 120 is provided with two pieces distributed along the up-down direction. Figure 3 In the embodiment, the second cutting member 130 moves to the position of the first cutting member 120 located at the lower side and cooperates with the first cutting member 120 located at the lower side; or the second cutting member 130 moves to the position of the first cutting member 120 located at the upper side and cooperates with the first cutting member 120 located at the upper side (according to Figure 3 (As can be imagined, additional drawings are not provided.) Compared with the second cutting member 130 cooperating with both upper and lower first cutting members 120 simultaneously, the second cutting member 130 cooperating with a single first cutting member 120 cuts fewer entanglements and has lower operating resistance, thus requiring less driving force. Furthermore, with the same driving force, the second cutting member 130 cooperates better with a single first cutting member 120, resulting in a better cutting effect.

[0040] According to the cleaning roller brush 100 provided in the embodiment of the present application, the second cutting piece 130 cooperates with different first cutting pieces 120 to cut entanglements at different positions on the shell 110, ensuring a single cutting effect while also ensuring an overall cleaning effect. The frequency of use of a single first cutting piece 120 is reduced, the wear rate is reduced, the durability of the device is improved, and the durability of the entire cleaning roller brush 100 is improved.

[0041] See also Figure 3 and Figure 4 , Figure 4 This is a schematic diagram of the partial structure of the cleaning roller brush 100 provided in an embodiment of the present application. The first cutting piece 120 can be provided with a first cutting portion 121, and at least part of the first cutting portion 121 extends out of the shell 110. The second cutting piece 130 is provided with multiple second cutting portions 131. The first cutting portion 121 and the second cutting portion 131 can be arranged along the extension direction of the shell 110. When the second cutting piece 130 moves to the corresponding position, at least one second cutting portion 131 can extend out of the shell 110 and cooperate with the corresponding first cutting portion 121 for cutting.

[0042] By arranging the first cutting portion 121 and the second cutting portion 131 along the X-direction, the wound material wound radially around the housing 110 can be effectively cut. At least a portion of the first cutting portion 121 is fixedly disposed outside the housing 110. When the second cutting member 130 moves to a position corresponding to the first cutting member 120, the second cutting portion 131 of the second cutting member 130 extends out of the housing 110 and cooperates with the corresponding first cutting portion 121 for cutting. The housing 110 can be provided with an escape opening 111 extending along the X-direction to allow the first cutting portion 121 and the second cutting portion 131 to extend.

[0043] Specifically, if Figure 3 and Figure 4 As shown, taking the Y direction in the figure as the up and down direction, the first cutting piece 120 is provided with two distributed along the up and down directions as an example, and the second cutting piece 130 can be provided with second cutting parts 131 distributed on both sides. Figure 3 When the second cutting member 130 moves to the lower side, the lower second cutting portion 131 of the second cutting member 130 extends out of the housing 110 and cooperates with the first cutting portion 121 of the first cutting member 120 located at the lower side to cut the winding material located at the lower side, and the upper second cutting portion 131 of the second cutting member 130 is separated from the first cutting portion 121 of the first cutting member 120 located at the upper side; when the second cutting member 130 moves to the upper side (according to Figure 3It can be imagined that no additional drawings are provided), the upper second cutting portion 131 of the second cutting piece 130 extends out of the shell 110 and cooperates with the first cutting portion 121 of the first cutting piece 120 located on the upper side to cut the winding located on the upper side, and the lower second cutting portion 131 of the second cutting piece 130 is separated from the first cutting portion 121 of the first cutting piece 120 located on the lower side.

[0044] It can be understood that the windings are generally wound along the radial direction of the shell 110. There are cases where the length of some windings is less than the circumference of the shell 110, and some windings will still be wound on the surface of the shell 110 after shearing. In order to ensure the shearing and cleaning effect of the windings at various positions on the cleaning roller brush 100, at least two first cutting members 120 can be distributed along the circumference of the shell 110 to improve the cutting effect of the windings.

[0045] See also Figure 4 and Figure 5 , Figure 5 This is another partial structural schematic diagram of the cleaning roller brush 100 provided in an embodiment of the present application. According to some embodiments of the present application, a driving structure 150 that is dynamically coupled to the second cutting member 130 may be provided in the shell 110. One of the second cutting member 130 and the shell 110 may be provided with a first guide member 140a, and the other may be provided with a second guide member 140b that is guided and matched with the first guide member 140a. The second cutting member 130 is configured to move back and forth between at least two first cutting members 120 along the first guide member 140a under the drive of the driving structure 150.

[0046] The driving structure 150 can be installed in the shell 110, and the driving structure 150 can apply a driving force to the second cutting member 130 to drive the second cutting member 130 to move relative to the shell 110, wherein the driving force applied by the driving structure 150 can be a driving force in a fixed direction, such as a driving force reciprocating along the X direction, to simplify the complexity of the driving structure 150.

[0047] One of the second cutting member 130 and the housing 110 may be provided with a first guide member 140a, and the other may be provided with a second guide member 140b that cooperates with the first guide member 140a. The first guide member 140a may define a fixed guide path, and the second guide member 140b cooperates with the first guide member 140a so that the second guide member 140b can move along the guide path defined by the first guide member 140a. Because the first guide member 140a and the second guide member 140b are respectively provided on the second cutting member 130 and the housing 110, the first guide member 140a defines the movement path of the second cutting member 130 relative to the housing 110. Therefore, the second cutting member 130 can move back and forth between the at least two first cutting members 120 along the guide path defined by the first guide member 140a under the action of a driving force in a fixed direction, so that the second cutting member 130 can cooperate with the at least two first cutting members 120 to cut, thereby ensuring the stability of the device operation.

[0048] See also Figure 4 In some embodiments, the first guide members 140a and the second guide members 140b can be provided in multiple pairs, and the multiple pairs of the first guide members 140a and the second guide members 140b can be arranged at intervals along the X direction. By providing multiple pairs of the first guide members 140a and the second guide members 140b, multiple positions of the second cutting member 130 are constrained to improve the stability of the movement of the second cutting member 130. The first guide members 140a and the second guide members 140b can be provided in two or more pairs, and the specific number is not limited here. For example, Figure 4 In the embodiment, two pairs of the first guide members 140a and the second guide members 140b may be provided.

[0049] According to some embodiments of the present application, the first guide member 140a may be an annular structure, and the second cutting member 130 may move back and forth between at least two first cutting members 120 along an annular trajectory.

[0050] By setting the first guide member 140a as a ring structure, the guide track of the first guide member 140a is ring-shaped. When the second cutting member 130 moves along the first guide member 140a, the running track of the second cutting member 130 is also ring-shaped, thereby facilitating the second cutting member 130 to perform a circular motion, and when it moves to different positions, it can cooperate with different first cutting members 120.

[0051] See also Figures 6 to 9 , Figures 6 to 9 They are schematic diagrams of the partial structures of the cleaning roller brush 100 when the second cutting member 130 moves to different positions.

[0052] In some embodiments, the first cutting portion 121 and the second cutting portion 131 can be arranged in a sawtooth shape along the X direction. The tooth blade portion of the first cutting portion 121 is arranged outside the shell 110. When the winding is wound around the peripheral side of the shell 110, it will also fall between the tooth blades of the first cutting portion 121. The tooth blades of the first cutting portion 121 and the second cutting portion 131 are staggered to cut off the winding trapped in the first cutting portion 121. The shape of the tooth blades of the first cutting portion 121 and the second cutting portion 131 is not limited here. For example, Figures 6 to 9 In the embodiment, the tooth edges of the first cutting portion 121 and the second cutting portion 131 are straight tooth edges; in another example, the tooth edges of the first cutting portion 121 and the second cutting portion 131 can also be arc-shaped to reduce the probability of the winding being separated from the tooth edge interval of the first cutting portion 121.

[0053] Among them, Figures 6 to 9 A state diagram of the second cutting member 130 at different positions during a movement cycle in one embodiment of the present application is shown, which will be described in detail below.

[0054] by Figure 6 The position of the second cutting member 130 is in the initial state. At this time, the second guide member 140b is located on the right side of the first guide member 140a, and the second cutting member 130 is located between the two first cutting members 120. When the driving mechanism 150 drives the second cutting member 130 to move, the second guide member 140b moves along the first guide member a.

[0055] like Figure 7 As shown, when the second guide member 140b moves to the lower side of the first guide member 140a along the guide track of the first guide member 140a, the first guide member 140a also moves to the lower side and cooperates with the first cutting member 120 located at the lower side to cut. Figure 6 Change to Figure 7 During the cutting process, the second cutting member 130 moves along the Y direction close to the first cutting member 130 located at the lower side, and generates relative displacement in the X direction so that the lower second cutting portion 131 cooperates with the first cutting portion 121 of the upper first cutting member 120 for cutting.

[0056] like Figure 8 As shown, the second guide member 140b continues to move to the left side of the first guide member 140a, and the second cutting member 130 returns to the neutral position between the two first cutting members 120. It can be understood that Figure 7 Change to Figure 8 During the cutting process, there is still relative displacement between the second cutting portion 131 and the first cutting portion 121 in the X direction to facilitate cutting.

[0057] like Figure 9As shown, when the second guide member 140b continues to move along the guide track of the first guide member 140a to the upper side of the first guide member 140a, the first guide member 140a also moves to the upper side and cooperates with the first cutting member 120 located on the upper side to cut. Figure 8 Change to Figure 9 During the cutting process, the second cutting member 130 moves along the Y direction close to the first cutting member 130 on the upper side, and generates relative displacement in the X direction so that the upper second cutting portion 131 cooperates with the first cutting portion 121 of the upper first cutting member 120 for cutting.

[0058] Then by Figure 9 Back to Figure 6 The state completes a motion cycle.

[0059] According to some embodiments of the present application, a stop structure for limiting the movement of the second guide member 140b in one direction may be provided on the first guide member 140a.

[0060] The second cutting member 130 moves to different positions along the annular trajectory to achieve cooperation with different first cutting members 120. If the second cutting member 130 is unable to perform a complete annular motion, it may not be able to cooperate with some of the first cutting members 120 for cutting. Therefore, when the drive structure applies a simple reciprocating driving force, it is necessary to prevent the second guide member 140b from reciprocating along a single side of the annular structure. By providing a stop structure, the second guide member 140b is limited to a complete annular motion along the first guide member 140a in a fixed direction. This ensures that the second cutting member 130 can pass through multiple first cutting members 120 in sequence when moving along the annular trajectory, thereby improving the stability of the device operation.

[0061] In some embodiments, the first guide member 140a may be a protrusion, and the second guide member 140b may be a slider that cooperates with the first guide member 140a.

[0062] See also Figure 10 According to some embodiments of the present application, the first guide member 140a may be a guide groove 141 , and the second guide member 140b may be a guide rod 142 movably disposed in the guide groove 141 .

[0063] The guide rod 142 can be extended into the guide groove 141 and cooperate with the guide groove 141, so that the guide rod 142 can move in the guide groove 141 along the shape trajectory of the guide groove 141, so that the shape trajectory of the guide groove 141 defines the guide trajectory of the first guide member 140a, and by arranging the guide groove 141 and the guide rod 142 on the second cutting member 130 and the shell 110 respectively, the second cutting member 130 can move along the guide trajectory defined by the guide groove 141.

[0064] In one example, see Figure 10 The guide groove 141 can be set on the shell 110, the guide rod 142 can be set on the second cutting piece 130, the guide rod 142 is fixed on the second cutting piece 130 along its radial direction, the guide groove 141 is fixed relative to the shell 110, and the second cutting piece 130 can move according to the shape trajectory of the guide groove 141 under the drive of the guide rod 142.

[0065] In another example, the guide groove 141 can be set on the second cutting member 130, and the guide rod 142 can be set on the shell 110. The guide rod 142 is fixed relative to the shell 110. When the second cutting member 130 is subjected to driving force, it moves along the guide track under the constraints of the guide groove 141 and the guide rod 142.

[0066] See also Figure 10 According to some embodiments of the present application, the cleaning roller brush 100 may further include an elastic member 144 , which can provide an elastic force to press the second cutting member 130 toward the first cutting member 120 .

[0067] It can be understood that when the first cutting piece 120 and the second cutting piece 130 cooperate to cut, it is necessary to keep the first cutting piece 120 and the second cutting piece 130 close to each other to improve the cutting effect and prevent the entanglement from entering the gap between the first cutting piece 120 and the second cutting piece 130. By setting the elastic piece 144, the second cutting piece 130 and the first cutting piece 120 are kept close to each other to improve the cutting effect.

[0068] The elastic member 144 can be mounted on the second cutting member 130 or on the housing 110. In one example, taking the elastic member 144 being mounted on the housing 110 as an example, the elastic member 144 is disposed on the housing 110 on the side of the second cutting member 130 facing away from the first cutting member 120. One end of the elastic member 144 is fixedly mounted on the housing 110, and the other end is slidably connected to the second cutting member 130, so that the elastic member 144 can continuously apply an elastic force to the second cutting member 130 toward the first cutting member 120.

[0069] See also Figure 10 According to some embodiments of the present application, one of the second cutting member 130 and the shell 110 is provided with a guide rod 142, and the other is provided with a guide groove 141, and the guide rod 142 is movably arranged in the guide groove 141; the elastic member 144 can be connected to the guide rod 142, and the guide groove 141 is provided on the side of the second cutting member 130 away from the first cutting member 120, and the guide rod 142 abuts against the bottom of the guide groove 141 to apply an elastic force to the second cutting member 130 toward the first cutting member 120.

[0070] The elastic member 144 can be connected to the guide rod 142 to apply an elastic force to the guide rod 142. By setting the guide groove 141 on the side of the second cutting member 130 away from the first cutting member 120, the elastic member 144 can apply an elastic force toward the bottom of the guide groove 141 on the end of the guide rod 142. While the guide rod 142 slides in the guide groove 141, the guide rod 142 and the bottom of the guide groove 141 interact with each other to apply an elastic force to the second cutting member 130 toward the first cutting member 120, so that the second cutting member 130 and the first cutting member 120 are kept tightly against each other.

[0071] In addition, in combination with the aforementioned technical solution, at least part of the bottom of the groove section 141a is inclined, and along the head to the tail of the groove section 141a, there is at least a section with a gradually decreasing depth. When the guide rod 142 passes through the inclined portion, the second cutting member 130 just cooperates with the first cutting member 120. Under the action of the inclined surface, the guide rod 142 compresses the elastic member 144, the elastic potential energy increases and the elastic force increases, so that the second cutting member 130 is further pressed against the first cutting member 120, thereby improving the pressing and cutting effects.

[0072] In some embodiments, the guide groove 141 can be set on the second cutting piece 130, and the guide rod 142 is installed on the shell 110 through the elastic piece 144. The elastic piece 144 applies an elastic force toward the guide groove 141 to the guide rod 142, so that the second cutting piece 130 remains tightly against the first cutting piece 120.

[0073] See also Figure 10 According to some embodiments of the present application, a guide groove 141 may be provided in the housing 110 , and an end of the guide rod 142 away from the guide groove 141 may be connected to the second cutting member 130 via an elastic member 144 .

[0074] The guide groove 141 is fixedly mounted on the housing 110, and the end of the guide rod 142 close to the guide groove 141 extends into the guide groove 141 and abuts against the bottom of the guide groove 141. The end of the guide rod 142 away from the guide groove 141 is connected to the second cutting member 130 through an elastic member 144. The elastic member 144 is in a compressed state and can move together with the guide rod 142 to apply an elastic force toward the first cutting member 120 to the second cutting member 130 through the elastic member 144.

[0075] In some embodiments, the elastic member 144 can be disposed on a side of the second cutting member 130 away from the first cutting member 120 , and the end of the elastic member 144 connected to the guide rod 142 is spaced apart from the second cutting member 130 to provide space for the guide rod 142 to move elastically.

[0076] See also Figure 10 and Figure 11According to some embodiments of the present application, the elastic member 144 may include a fixed section 144a and a connecting section 144b, the fixed section 144a is fixedly connected to the second cutting member 130, the connecting section 144b is connected between the fixed section 144a and the guide rod 142, and the connecting section 144b and the guide rod 142 may be connected at an acute angle.

[0077] The elastic member 144 can be a rod-shaped setting that can be elastically deformed. The elastic member 144 can include a fixed section 144a fixedly connected to the second cutting member 130. The second cutting member 130 can be provided with a clamping structure protruding laterally. The fixed section 144a is fixedly connected to the second cutting member 130 by clamping the fixed section 144a in the clamping structure.

[0078] In one example, see Figure 10 and Figure 11 When the second cutting piece 130 is a metal piece, the clamping structure can be a stamped folding edge, and a plurality of spaced folding edges are formed by stamping, and the fixing section 144a is clamped between the plurality of folding edges to achieve fixation.

[0079] In another example, the fixing section 144a can also be fixedly connected to the second cutting member 130 by riveting, screw connection, sleeve connection, or other connection methods.

[0080] The elastic member 144 further includes a connecting section 144b connected between the fixed section 144a and the guide rod 142. To ensure the stability of the connection between the fixed section 144a and the second cutting member 130, the fixed section 144a is generally tightly connected to the second cutting member 130. By providing the connecting section 144b and connecting the connecting section 144b to the guide rod 142 at an acute angle, at least a portion of the connecting section 144b is spaced apart from the second cutting member 130, thereby facilitating elastic deformation of the connecting section 144b and applying an elastic force to the guide rod 142. The connecting section 144b and the fixed section 144a may be connected at an obtuse angle.

[0081] In some embodiments, the guide rod 142 and the elastic member 144 may be integrally formed. Both the guide rod 142 and the elastic member 144 are made of metal material and formed by bending.

[0082] See also Figure 10 and Figure 11 According to some embodiments of the present application, a connecting hole 132 may be provided on the second cutting member 130 , the guide rod 142 may pass through the connecting hole 132 , and the elastic member 144 may be provided on a side of the second cutting member 130 away from the guide groove 141 .

[0083] In this embodiment, the two first cutting members 120 are spaced apart from each other to avoid the elastic member 144 and the guide rod 142. A connecting hole 132 is provided in the second cutting member 130 along its thickness direction, and the guide rod 142 is passed through the connecting hole 132, so that the guide rod 142 is radially restrained relative to the second cutting member 130, facilitating the movement of the second cutting member 130 under the guidance of the guide rod 142. It will be understood that the guide rod 142 can be elastically moved axially within the connecting hole 132 under the action of the elastic member 144. By arranging the elastic member 144 on the side of the second cutting member 130 facing away from the guide groove 141, the installation space between the second cutting member 130 and the guide groove 141 is optimized, thereby improving space utilization.

[0084] See also Figure 11 According to some embodiments of the present application, the fixing section 144a may extend along the X direction.

[0085] Because the second cutting member 130 mainly achieves cutting by moving along the X direction and cooperating with the first cutting member 120, the fixing section 144a is arranged along the X direction to increase the connection length between the fixing section 144a and the second cutting member 130 in the X direction, thereby improving the stability of the connection between the fixing section 144a and the second cutting member 130.

[0086] See also Figure 11 According to some embodiments of the present application, the elastic member 144 may further include a bent extension segment 144c, where the extension segment 144c is connected between the connecting segment 144b and the fixing segment 144a.

[0087] The bent extension section 144c is configured to increase the elastically deformable length of the elastic member 144, thereby facilitating elastic deformation of the elastic member 144. Furthermore, the bent extension section 144c is configured to reduce the space occupied by the elastic member 144, thereby optimizing the spatial layout. In one example, the extended section 144c can be bent into a U-shape.

[0088] See also Figure 12 According to some embodiments of the present application, the guide groove 141 may include two groove sections 141 a connected end to end, and a stop surface 143 may be provided at the connection between the two groove sections 141 a.

[0089] In this embodiment, the projections of the two groove segments 141a in the depth direction do not overlap, so that the two groove segments 141a connected end to end constitute a closed guide groove 141 connected end to end. It should be noted that the closed guide groove 141 can be in the form of a circular ring, an elliptical ring or other irregular shapes, and there is no specific limitation.

[0090] The stop surface 143 can be used to limit the guide rod 142 from moving in one direction, and the guide rod 142 can stop against the stop surface 143. By setting the stop surface 143 to limit the guide rod 142 to move only in the direction of the stop surface 143, when the guide rod 142 moves in the opposite direction, it will stop against the stop surface 143 to limit its position. Therefore, when the structure of the guide groove 141 is complex, the guide rod 142 can be limited to move along a fixed direction according to the designed trajectory in the guide groove 141, thereby ensuring the stability of the movement of the second cutting member 130.

[0091] By arranging the stop surface 143 at the connection between the two slot segments 141 a , the guide rod 142 can only cross the connection between the two slot segments 141 a along a fixed direction.

[0092] For example, the two ends of a slot segment 141a are respectively a head and a tail, the head of one slot segment 141a is connected to the tail of another slot segment 141a', and the tail of the other slot segment 141a' is connected to the head of the slot segment 141a. The stop surface 143 is set at the head of the slot segment 141a and is arranged in a direction from the head to the tail of the slot segment 141a. When the guide rod 142 moves in the guide slot 141, it can only cross from the tail of the slot segment 141a to the head of the other slot segment 141a, and cannot cross the stop surface 143 from the head of the slot segment 141a to the tail of the other slot segment 141a'. Therefore, during a complete movement cycle, the guide rod 142 is constrained to move between the two slot segments 141a and can only pass through the two slot segments 141a in a fixed direction.

[0093] Taking the guide groove 141 as an example, which is in the shape of an elliptical ring, the two groove segments 141a are distributed along the short axis direction of the ellipse, so that the head and tail of the two groove segments 141a are respectively located at the long axis ends of the ellipse. In a complete motion cycle, the guide rod 142 performs a reciprocating motion along an elliptical ring motion trajectory in the guide groove 141; in an incomplete motion cycle, the guide rod 142 can only reciprocate in a single groove segment 141a.

[0094] Because the second cutting member 130 needs to make a reciprocating motion, a closed guide groove 141 connected end to end is provided to facilitate the guide rod 142 to move back and forth between two determined positions. Under the condition of ensuring the effective motion stroke of the second cutting member 130 as much as possible, the closed guide groove 141 occupies the minimum space and has a high space utilization rate.

[0095] See also Figure 12 and Figure 13 According to some embodiments of the present application, at least a portion of the bottom of the groove segment 141 a can be tilted so that a stop surface 143 is formed at the position where the two groove segments 141 a are connected.

[0096] By setting at least a portion of the bottom of the groove segment 141a to be inclined, that is, the depth of the portion of the groove segment 141a at the bottom that is inclined is changed, so that a drop in the depth direction is formed at different positions of the groove bottom of the guide groove 141, and by setting the portion where the groove segment 141a is connected to another groove segment 141a to be inclined, so that a drop is formed at the position where the two groove segments 141a are connected, a stop surface 143 is formed.

[0097] Exemplarily, along the movement direction of the guide rod 142, the depth of the head of the groove segment 141a is greater than the depth of the tail, so that a depth difference is formed between the tail of the groove segment 141a and the head of the other groove segment 141a, so that the surface connecting the tail of the groove segment 141a and the head of the other groove segment 141a is the stop surface 143, and the stop surface 143 is set toward the movement direction of the guide rod 142.

[0098] It should be noted that the bottom of the groove section 141a can be completely inclined or partially inclined. For example, the bottom wall near the head of the groove section 141a is flat, that is, the depth of the groove bottom near the head of the groove section 141a remains unchanged, and the bottom wall near the tail of the groove section 141a is inclined.

[0099] See also Figure 12 and Figure 13 In some embodiments, the bottom wall of the slot segment 141a may include a first inclined surface 141b and a second inclined surface 141c, which are connected sequentially along the direction from the beginning to the end of the slot segment 141a. Along the direction from the beginning to the end of the slot segment 141a, the first inclined surface 141b is inclined toward the slot opening, while the second inclined surface 141c is inclined away from the slot opening. It is understood that the end of the second inclined surface 141c near the end of the slot segment 141a is spaced apart from the bottom of the slot at the beginning of the other slot segment 141a to form a stop surface 143. The end of the second inclined surface 141c near the end of the slot segment 141a is connected to the stop surface 143.

[0100] By providing the first inclined surface 141b, in the portion provided with the first inclined surface 141b, the depth of the groove segment 141a gradually decreases from the head to the tail of the groove segment 141a, so that a step is formed between the tail of the groove segment 141a and the head of the other groove segment 141a; when the guide rod 142 moves in the guide groove 141, the end of the guide rod 142 can abut against the bottom of the guide groove 141, especially when the depth of the groove segment 141a becomes shallower, by providing the second inclined surface 141c, when the guide rod 142 moves to the tail of the groove segment 141a and is about to enter the head of the other groove segment 141a, a downward slope is formed, which facilitates the end of the guide rod 142 to slide into the other groove segment 141a along the second inclined surface 141c.

[0101] See also Figure 12 and Figure 13 In some embodiments, the stop surface 143 is tangent to the side wall of the slot segment 141a close to the other slot segment 141a, and is inclined from the head to the tail of the slot segment 141a in a direction away from the other slot segment 141a.

[0102] The stop surface 143 in one slot segment 141a is tangent to the side wall of the slot segment 141a close to the other slot segment 141a' at one end thereof, so that the stop surface 143 is connected to the side wall of the slot segment 141a more smoothly, thereby reducing the movement resistance of the guide rod 142. When the guide rod 142 is located at the head of the slot segment 141a and moves toward the tail, the guide rod 142 will abut against the side wall of the slot segment 141a close to the other slot segment 141a. By setting the end of the stop surface 143 connected to the side wall of the slot segment 141a close to the other slot segment 141a to be inclined in the direction from the head to the tail of the slot segment 141a toward the direction away from the other slot segment 141a, the reaction force applied to the guide rod 142 by the side wall and the stop surface 143 is directed toward the slot segment 141a where the guide rod 142 is located, thereby ensuring that the guide rod 142 can move more easily along the head to the tail of the slot segment 141a.

[0103] In other embodiments, the guide groove 141 may be arranged in an 8-shape, and the movement trajectory of the guide rod 142 in the guide groove 141 is in an 8-shape.

[0104] In some other embodiments, the guide groove 141 can be set in an open shape such as a broken line or a sine curve, and the guide rod 142 reciprocates at both ends of the guide groove 141. It should be noted that when the guide groove 141 is in an open shape, the stop surface 143 may not be set in the guide groove 141.

[0105] According to some embodiments of the present application, the two slot sections 141 a are respectively arranged close to the two first cutting members 120 . When the guide rod 142 slides in one of the slot sections 141 a , the second cutting member 130 can cooperate with the corresponding first cutting member 120 for cutting.

[0106] Taking the example of two first cutting members 120 being distributed along the Y direction, the two slot sections 141a are also distributed along the Y direction and extend along the extension direction of the housing 110, so that the two slot sections 141a are respectively disposed adjacent to the two first cutting members 120. Taking the example of a guide slot 141 disposed on the housing 110 and a guide rod 142 disposed on the second cutting member 130, when the guide rod 142 slides into one of the slot sections 141a, the second cutting member 130 can cooperate with the first cutting member 120 adjacent to the slot section 141a. As the guide rod 142 slides along the slot section 141a, the second cutting member 130 slides along the X direction to achieve coordinated cutting with the first cutting member 120.

[0107] See also Figure 14 According to some embodiments of the present application, the driving structure 150 may include a sliding member 151, a connecting member 152 and a reset member 153. The sliding member 151 can be slidably installed in the shell 110, the connecting member 152 can be rotatably connected between the sliding member 151 and the second cutting member 130, and the reset member 153 is connected between the shell 110 and the second cutting member 130.

[0108] The slider 151 is configured to slide under the action of an external driving force and to propel the second cutting member 130 to move. For example, if the first cutting portion 121 and the second cutting portion 131 are arranged along the X-direction, the second cutting member 130 primarily cuts along the X-direction. The slider 151 can be slidably mounted within the housing 110 along the X-direction to improve work efficiency. The slider 151 can be positioned at an end portion of the housing 110 in the direction in which the housing 110 extends, so that an external driving force can be applied to the slider 151.

[0109] One end of the connecting member 152 is rotatably connected to the sliding member 151, and the other end is rotatably connected to the second cutting member 130. During the movement, the second cutting member 130 not only needs to perform cutting, but also needs to move back and forth between the two first cutting members 120. Therefore, the second cutting member 130 not only moves in the X direction, but also needs to move upward in the Y direction. The connecting member 152 is provided to facilitate the dynamic coupling connection between the sliding member 151 and the second cutting member 130.

[0110] The reset member 153 is connected between the second cutting member 130 and the housing 110 to apply a reset force to the second cutting member 130, wherein the sliding member 151 only applies a force in one direction to the second cutting member 130 to push the second cutting member 130 to move in one direction. By setting the reset member 153 to apply a reset force opposite to the sliding member 151 to the second cutting member 130, it is easy to reset the second cutting member 130. It can be understood that the sliding member 151 applies a pushing force intermittently, and the pushing force is greater than the reset force of the reset member 153. For the sake of the intermittent pushing force, the reset member 153 drives the second cutting member 130 to return to its initial position. For example, the reset member 153 can be a spring, the first end of the spring is connected to the second cutting member 130, the second end of the spring is connected to the housing 110, and the second end of the spring is located on the side of the first end close to the sliding member 151.

[0111] In actual execution, the initial position of the guide rod 142 is located at the head of the groove section 141a, and the external driving force drives the sliding member 151 to slide along the X direction. The sliding member 151 pushes the connecting member 152 to drive the second cutting member 130 to move, and the second cutting member 130 drives the guide rod 142 to move along the head of the groove section 141a to the tail. During this process, the second cutting member 130 cooperates with one of the first cutting members 120 to cut until the guide rod 142 enters the head of another groove section 141a'. At this time, the external driving force disappears intermittently, and the reset member 153 drives the second cutting member 120 to move. The second cutting piece 130 moves to drive the guide rod 142 to slide along the head of another slot segment 141a' to the tail of another slot segment 141a'. During this process, the second cutting piece 130 cooperates with the other first cutting piece 120 to cut until the guide rod 142 enters the head of the initial slot segment 141a. The second cutting piece 130 pushes the connecting piece 152 and the sliding piece 151 in the opposite direction to return to the initial position. This is one cycle. The external driving force appears and pushes the sliding piece 151 to slide. This cycle can achieve repeated cutting of the winding material wrapped on the shell 110.

[0112] The driving structure 150 provided in the embodiment of the present application has a simple structure, low cost, high operational stability, and can achieve multi-directional movement of the second cutting member 130 with the cooperation of the guide structure 140 by applying a simple driving force.

[0113] See also Figure 14 and Figure 15 According to some embodiments of the present application, a driving portion 151a may be provided at the end of the sliding member 151 away from the connecting member 152, and a driving inclined surface 151b may be provided at the end surface of the driving portion 151a away from the connecting member 152. The driving inclined surface 151b is used to cooperate with the power mechanism 200 to make the sliding member 151 slide.

[0114] By providing a driving portion 151a and a driving bevel 151b, the sliding member 151 is driven to slide in cooperation with an external power mechanism 200. There are at least two driving bevels 151b. For example, the driving bevels 151b can be spirally arranged with the sliding direction of the sliding member 151 as the axis, and the two driving bevels 151b are spaced apart along the circumference of the driving portion 151a. The power mechanism 200 is used to apply an external driving force to the sliding member 151. The power mechanism 200 can be provided with a power surface that cooperates with the driving bevel 151b. When the driving portion 151a and the power mechanism 200 rotate relative to each other, the relative action of the power surface and the driving bevel 151b pushes the driving portion 151a to move in a direction away from the power mechanism 200, thereby pushing the second cutting member 130 to move. When the power surface and the driving bevel 151b are separated, the sliding member 151 can be reset.

[0115] Based on the same utility model concept, the present application also provides a cleaning device, which includes a main body and the above-mentioned cleaning roller brush 100, which is mounted on the main body. The main body is the main structure of the entire cleaning device, wherein the cleaning device can be a sweeping robot, a floor scrubber, a vacuum cleaner, etc.

[0116] See also Figure 14 and Figure 15 The cleaning device may further include a power mechanism 200, which may be fixedly mounted on the main body. When the cleaning roller brush 100 rotates for cleaning, because the drive structure 150 is disposed within the housing 110, the housing 110 drives the drive structure 150 to rotate together, thereby causing the slider 151 and the drive portion 151a at the end of the slider 151 to rotate relative to the main body, thereby causing the drive portion 151a to rotate relative to the power mechanism 200 mounted on the main body, thereby causing the drive portion 151a to move along the X-direction under the action of the power mechanism 200, thereby driving the slider 151, the connecting member 152, and the second cutting member 130 to move, thereby achieving cutting. This structure is simple in construction, low in cost, and stable in operation. During the operation of the cleaning roller brush 100, the cutting of entangled materials can be completed by utilizing the rotation of the cleaning roller brush 100 itself.

[0117] In some embodiments, the power mechanism 200 may include a drive motor, which may be connected to the power surface by power coupling. The drive motor applies torque to drive the power surface to actively rotate, so that the entangled material can be cut even when the cleaning roller brush 100 is not rotating, which has stronger functionality, better cutting effect and higher cutting efficiency.

[0118] Based on the same utility model concept, the embodiment of the present application also provides a cleaning system, which includes a cleaning base station and the above-mentioned cleaning device. The cleaning base station can have functions such as charging the cleaning device, cleaning the cleaning device, and collecting impurities from the cleaning device.
