[0041] With the development of science and technology, cleaning equipment has become increasingly popular. Most cleaning equipment uses a cleaning roller brush to achieve the cleaning function of the floor. During the cleaning process, hair and other linear objects on the floor can easily be entangled on the outer circumference of the cleaning roller brush. If there are many entangled objects, the cleaning function will be affected at best, and the cleaning roller brush may be blocked and damaged at worst. Therefore, the embodiments of the present application provide a cleaning roller brush, a cleaning device, and a cleaning system. The cleaning roller brush, cleaning device, and cleaning system provided by the embodiments of the present application can automatically clear the entangled objects entangled on the cleaning roller brush during the cleaning process, reduce the impact of the entangled objects on the cleaning roller brush, improve the working effect of the cleaning roller brush, and increase the service life of the cleaning roller brush.

[0046] See also Figure 1 , Figure 1 An embodiment of a cleaning device 20 is shown. The cleaning device 20 includes a main body 22, a drive mechanism 21, and a cleaning roller brush 100. One end of the cleaning roller brush 100 is connected to the drive mechanism 21. Driven by the drive mechanism 21, the cleaning roller brush 100 rotates relative to the main body 22 of the cleaning device 20 to clean the surface to be cleaned. During the cleaning process, the cleaning device 20 can automatically remove entangled objects wrapped around the cleaning roller brush 100, reducing the impact of entangled objects on the cleaning roller brush 100 and the cleaning process, thereby improving the service life of the cleaning roller brush 100 and its working performance. The cleaning device 20 can be a sweeping robot, a floor scrubber, a vacuum cleaner, etc.

[0047] like Figure 2 and Figure 3 As shown, Figure 2 and Figure 3 An embodiment of a cleaning roller brush 100 is shown, which includes a shell 110, a cleaning strip 120 and a first cutting piece 130a and a second cutting piece 130b installed on the shell 110, wherein the cleaning strip 120 is wound around the outer surface of the shell 110, and the first cutting piece 130a and the second cutting piece 130b extend from the outer surface of the shell 110.

[0048] The shell 110 can provide an installation base for structures such as the cleaning strip 120 and the cutting piece 130. The shell 110 is roughly cylindrical, and one end of the shell 110 is connected to the driving mechanism 21 of the cleaning device 20, so that the cleaning strip 120 can rotate relative to the surface to be cleaned under the drive of the driving mechanism 21, thereby cleaning the surface to be cleaned. It should be noted that the extension direction of the roughly cylindrical shell 110 refers to the axial direction of the shell 110. As for the structure of the shell 110, the shell 110 may include a detachably connected upper shell 117 and a lower shell 118. If the internal cutting piece 130 needs to be repaired, the upper shell 117 and the lower shell 118 can be separated to expose the first cutting piece 130a and the second cutting piece 130b, so that the first cutting piece 130a and the second cutting piece 130b can be repaired or replaced.

[0049] Among them, the first cutting piece 130a and the second cutting piece 130b extending on the outer surface of the shell 100 means that at least part of the first cutting piece 130a and the second cutting piece 130b can protrude from the outer surface of the shell 110, so that the first cutting piece 130a and the second cutting piece 130b can cut the windings wrapped around the shell 110.

[0050] The cleaning strip 130 is disposed in the gap between the first cutting member 130a and the second cutting member 130b, indicating that the first cutting member 130a and the second cutting member 130b are spaced apart. Since both the first cutting member 130a and the second cutting member 130b have relatively sharp blades, in order to avoid interference between the first cutting member 130a and the second cutting member 130b, the first cutting member 130a and the second cutting member 130b can be spaced apart.

[0051] The cleaning strip 130 is arranged in the gap between the first cutting piece 130a and the second cutting piece 130b, so that the cutting pieces 130 are provided on both sides of the cleaning strip 120. The cleaning strip 130 can be a sheet structure, and the two sides of the cleaning strip 130 refer to the two sides of the thickness direction of the cleaning strip 130.

[0052] As the cleaning device 20 rotates the cleaning roller brush 100, hair and other linear objects may become entangled around the outer circumference of the housing 110 as the housing 110 rotates. Since the cleaning strip 120 protrudes from the outer circumference of the housing 110, the objects become entangled around the portion of the housing 110 where the cleaning strip 120 is located. In essence, the objects become entangled around the outer circumference of the cleaning strip 120 (the portion of the cleaning strip 120 that is away from the top surface of the housing 110). If the cleaning strip 120 is elastic, the objects may become entangled around the cleaning strip 120, thereby affecting the cleaning of the surface to be cleaned by the cleaning strip 120. The cleaning strip 120 is arranged in the gap between the first cutting piece 130a and the second cutting piece 130b, so that cutting structures are provided on both sides of the cleaning strip 120 in the thickness direction. When linear windings such as hair are wound around the cleaning strip 120, the first cutting piece 130a and the second cutting piece 130b arranged on both sides of the cleaning strip 120 can work at the same time and can both cut the windings, thereby increasing the cutting force on the windings wound around the cleaning strip 120, cutting off the windings, avoiding the windings around the housing 110 as much as possible, reducing the influence of the windings on the cleaning roller brush 100, improving the working effect of the cleaning roller brush 100, and increasing the service life of the cleaning roller brush 100.

[0053] The cleaning strip 120 protrudes from the outer surface of the housing 110 and can be wound around the outer circumferential surface of the housing 110. Specifically, the cleaning strip 120 can be arranged along the axial direction of the housing 110 and wound around the circumference of the housing 110. Because the cleaning strip 120 is wound around the outer surface of the housing 110, and the outer surface of the housing 110 is generally cylindrical, at least a portion of the cleaning strip 120 is arc-shaped or spiral-shaped (arc-shaped when the number of windings is less than one, spiral-shaped when the number of windings is multiple). The arc-shaped or spiral-shaped cleaning strip 120 has a certain guiding effect on the wound object, allowing the wound object to move along the extension direction (axial direction) of the housing 110.

[0054] The arc-shaped or spiral-shaped cleaning strip 120 has a certain guiding effect on the entangled objects. The cleaning strip 120 is arranged between the first cutting piece 130a and the second cutting piece 130b, so that under the guidance of the cleaning strip 120, the first cutting piece 130a and the second cutting piece 130b can cut the entangled objects as much as possible, thereby avoiding the situation where the first cutting piece 130a or the second cutting piece 130b concentrates on cutting entangled objects such as hair, reducing the situation where a single first cutting piece 130a or a single second cutting piece 130b is severely worn due to long-term cutting, thereby improving the service life of the first cutting piece 130a or the second cutting piece 130b.

[0055] It should be noted that the first cutting member 130a and the second cutting member 130b extend on the outer surface of the housing 110. The first cutting member 130a and the second cutting member 130b may be arranged along the axial direction of the housing 110. In some embodiments, the first cutting member 130a and the second cutting member 130b may be on the same axis of the housing 110 (e.g., Figure 1 and Figure 2 shown).

[0056] In these embodiments, the cleaning strip 120 may be spiral-shaped. The cleaning strip 120 may be partially or entirely spirally arranged, and during the synchronous rotation of the cleaning strip 120 and the housing 110, the winding object may move along with the spirally arranged cleaning strip 120.

[0057] As the cleaning device 20 rotates the cleaning roller brush 100, hair and other linear entanglements may become entangled on the outer circumference of the cleaning strip 120 as the housing 110 rotates. Since the housing 110 is long and narrow, the entanglements may become entangled at different locations on the housing 110. However, after the first cutting member 130a and the second cutting member 130b are installed on the housing 110, their positions on the housing 110 are fixed, so the first cutting member 130a and the second cutting member 130b can only cut entanglements within their respective cutting areas.

[0058] Since the cleaning strip 120 is spirally arranged along the extension direction of the shell 110 (the axial direction of the shell 110), the winding can move in the extension direction of the shell 110 (the axial direction of the shell 110), and then the winding can move into the cutting area of ​​the first cutting piece 130a or the second cutting piece 130b, so that the first cutting piece 130a or the second cutting piece 130b can cut off the winding, avoiding the winding of the winding on the shell 110 as much as possible, reducing the influence of the winding on the cleaning roller brush 100, improving the working effect of the cleaning roller brush 100, and also improving the service life of the cleaning roller brush 100.

[0059] Among them, since the cleaning strip 120 is arranged in the gap between the first cutting piece 130a and the second cutting piece 130b, and the first cutting piece 130a and the second cutting piece 130b are spaced apart on the same axis of the shell 110, the winding material may be cut twice by the first cutting piece 130a and the second cutting piece 130b during the movement of the spirally arranged shell 110, which can increase the possibility of the winding material being cut off, and thus can avoid the winding of the winding material on the shell 110 and the cleaning strip 120 as much as possible, reduce the impact of the winding material on the cleaning roller brush 100, improve the working effect of the cleaning roller brush 100, and increase the service life of the cleaning roller brush 100.

[0060] In these embodiments, the cleaning bar 120 can be provided in plurality, and the first cutting member 130a and the second cutting member 130b can be provided in multiple groups. Specifically, the cleaning bar 120 can be provided in three, and the first cutting member 130a and the second cutting member 130b can be provided in two groups, and the two groups of first cutting members 130a and second cutting members 130b are respectively provided on different axes of the housing 110.

[0061] Since the number of cleaning bars 120 is different from the number of groups of the first cutting element 130a and the second cutting element 130b, there is a possibility that one of the cleaning bars 120 will not be arranged in the gap between the first cutting element 130a and the second cutting element 130b. However, a cleaning bar 120 must be arranged in the gap between the first cutting element 130a and the second cutting element 130b of the same group.

[0062] The above describes a specific embodiment of the arrangement of the cleaning strip 120 in which the first cutting member 130a and the second cutting member 130b are located on the same axis of the housing 110. The following describes a shape and arrangement of the cleaning strip 120 in which the first cutting member 130a and the second cutting member 130b are located on different axes of the housing 110. Figure 4 and Figure 5 shown.

[0063] In these embodiments, the first cutting member 130a and the second cutting member 130b are located on different axes of the housing 110. This arrangement does not limit the shape of the cleaning strip 120. The cleaning strip 120 can be linear and arranged along the axis of the housing 110. The cleaning strip 120 can also be arc-shaped and arranged between the first cutting member 130a and the second cutting member 130b. In these embodiments, the cleaning strip 120 can also have a multi-segment structure. The first cutting member 130a and the second cutting member 130b can be arranged in multiple groups, and a section of the cleaning strip 120 can be arranged between each group of the first cutting member 130a and the second cutting member 130b.

[0064] Specifically, in these embodiments, the cleaning strip 120 includes a first cleaning section 122 and a second cleaning section 123. The first cleaning section 122 and the second cleaning section 123 are arranged in sequence along the axial direction of the shell 110. The first cleaning section 122 is arranged between the corresponding first cutting piece 130a and the second cutting piece 130b, and the second cleaning section 123 is arranged between the corresponding first cutting piece 130a and the second cutting piece 130b.

[0065] The first cleaning section 122 and the second cleaning section 123 are arranged in sequence along the axial direction of the shell 110, which means that the first cleaning section 122 and the second cleaning section 123 are arranged along the extension direction of the shell 110, and the first cleaning section 122 and the second cleaning section 123 are located at different positions of the shell 110 in the extension direction of the shell 110, and the first cleaning section 122 and the second cleaning section 123 are staggered in the axial direction of the shell 110.

[0066] The first cleaning section 122 and the second cleaning section 123 may extend in different directions, that is, the first cleaning section 122 and the second cleaning section 123 may be arranged in different directions. That is, if the first cleaning section 122 and the second cleaning section 123 are both spiral-shaped, the first cleaning section 122 and the second cleaning section 123 may have opposite directions of rotation. This allows the first cleaning section 122 and the second cleaning section 123 to guide the windings in different directions, thereby minimizing the accumulation of windings in one direction, which would result in a larger cutting amount for the corresponding first cutting member 130a and the second cutting member 130b, and lead to faster wear of the first cutting member 130a and the second cutting member 130b.

[0067] In these embodiments, the two first cutting members 130a in different groups may be disposed on the same axis of the housing 110 or on different axes of the housing 110. Similarly, the two second cutting members 130b in different groups may be disposed on the same axis of the housing 110 or on different axes of the housing 110.

[0068] In these embodiments, along the extension direction of the housing 110 , the cutting areas of the first cutting member 130 a and the second cutting member 130 b of the same group at least partially overlap.

[0069] The cutting area of ​​the first cutting member 130a refers to the cutting length of the first cutting member 130a in the axial direction of the housing 110. The cutting area of ​​the second cutting member 130b refers to the cutting length of the second cutting member 130b in the axial direction of the housing 110.

[0070] The cutting areas of the first cutting piece 130a and the second cutting piece 130b at least partially overlap, indicating that the cutting ranges of the first cutting piece 130a and the second cutting piece 130b in the extension direction of the shell 110 have overlapping parts. In the axial direction of the shell 110, the first cutting piece 130a and the second cutting piece 130b are avoided as much as possible to avoid the occurrence of a cutting blind area, thereby improving the cleaning effect of the entangled objects, and further improving the cleaning effect of the cleaning roller brush 100.

[0071] In addition, when the first cutting piece 130a and the second cutting piece 130b are cutting the windings, the ends are mostly the first to contact and cut the windings. As the cutting process continues, the cutting force of the edges of the first cutting piece 130a and the second cutting piece 130b is weakened compared to the cutting force of the middle part. Since the cutting areas of the first cutting piece 130a and the second cutting piece 130b overlap, the edge areas with slightly weaker cutting force can be cut by the first cutting piece 130a and the second cutting piece 130b at the same time, which can also improve the cleaning effect of the windings.

[0072] The above describes the positional relationship between the first cutting member 130a, the second cutting member 130b, and the cleaning bar 120. The following describes in detail the specific structures of the first cutting member 130a and the second cutting member 130b and how they are installed within the housing 110. The first cutting member 130a and the second cutting member 130b have the same structure. For ease of description, the first cutting member 130a and the second cutting member 130b are collectively referred to as cutting members 130.

[0073] It should be noted that, whether Figure 2 and Figure 3 The cleaning roller brush 100 provided in Figure 4 and Figure 5 The cleaning roller brush 100 provided in the embodiment, its internal structure and the arrangement of the cutting element 130 can be set according to the following conditions.

[0074] See also Figure 6 and Figure 7 , Figure 6 A schematic diagram showing the internal structure of the cleaning roller brush 100 is shown. Figure 7 Shown Figure 6 A partial enlarged view of point B in the figure. The cleaning roller brush 100 further includes a transmission member 140, which can drive the cutting member 130 to reciprocate relative to the housing 110, thereby cutting the entangled material. The cutting member 130 can include a first cutting blade 132 and a second cutting blade 134. The first cutting blade 132 is movable relative to the housing 110, and the second cutting blade 134 is fixedly connected to the housing 110.

[0075] The second cutting knife 134 is fixedly connected to the shell 110, and the second cutting knife 134 can be considered as a fixed knife. The first cutting knife 132 can move relative to the shell 110, and the first cutting knife 132 can be considered as a movable knife. As for the movement mode of the first cutting knife 132 relative to the shell 110, it can be rotation or movement. The first cutting knife 132 can move relative to the second cutting knife 134, so that the winding material can be cut with the cooperation of the first cutting knife 132 and the second cutting knife 134.

[0076] The first cutting knife 132 and the second cutting knife 134 move toward each other, and the cutting principle of the two is the same as the working principle of scissors, so that the entanglement is subjected to force from two different directions, which can increase the force applied to the entanglement, so that the entanglement can be cut quickly, thereby improving the cutting effect of the entanglement.

[0077] In order to improve the cutting effect of the first cutting blade 132 and the second cutting blade 134, the first cutting blade 132 and the second cutting blade 134 need to fit tightly together, wherein the cutting member 130 further includes an elastic member 135, which is disposed between the housing 110 and the first cutting blade 132. Under the restoring force of the elastic member 135, the first cutting blade 132 can always be pressed against the second cutting blade 134.

[0078] In some embodiments, the first cutting blade 132 has a plurality of first grooves 132 a , and the second cutting blade 134 has a plurality of second grooves 134 a . The corresponding first grooves 132 a and second grooves 134 a are at least partially overlapped.

[0079] The first cutting blade 132 includes a first body 132b and a plurality of first cutting portions 132c. The first body 132b is elongated and arranged along the axial direction of the housing 110. The plurality of first cutting portions 132c are sequentially spaced apart from the first body 132b, with a first groove 132a formed between adjacent first cutting portions 132c. Similarly, the second cutting blade 134 includes a second body 134b and a plurality of second cutting portions 134c. The second body 134b is elongated and arranged along the axial direction of the housing 110. The plurality of second cutting portions 134c are sequentially spaced apart from the second body 134b, with a second groove 134a formed between adjacent second cutting portions 134c.

[0080] The at least partial overlapping arrangement of the first groove 132a and the second groove 134a indicates that the first groove 132a and the second groove 134a can be completely connected or partially connected. During the cutting process, the winding material can fall into the overlapping area between the first groove 132a and the second groove 134a. The overlapping area can play a certain role in fixing the winding material, thereby enabling the winding material to be cut off with the cooperation of the first cutting portion 132c and the second cutting portion 134c.

[0081] Furthermore, because the first cutting blade 132 has multiple first cutting portions 132c and the second cutting blade 134 has multiple second cutting portions 134c, any one of the first cutting portions 132c and any one of the second cutting portions 134c can cooperate to cut the wound material. With each movement of the first cutting blade 132, the cooperation of the multiple first cutting portions 132c and the multiple second cutting portions 134c allows for multiple cuts of the wound material, thereby improving cutting efficiency.

[0082] It should be noted that the first cutting portion 132c is protruded from the first body 132b. It can be considered that the first cutting portion 132c has two side walls and a top wall. The two side walls respectively form a first groove 132a with the side walls of the two adjacent first cutting portions 132c. The blade can be set on both side walls and the top wall of the first cutting portion 132c, or on only two side walls, or on only one side wall.

[0083] Similarly, the second cutting portion 134c is protruded from the second body 134b. It can be considered that the second cutting portion 134c has two side walls and a top wall. The two side walls respectively form a second groove 134a with the side walls of the two adjacent second cutting portions 134c. The blade can be set on both side walls and the top wall of the second cutting portion 134c, or on only two side walls, or on only one side wall.

[0084] In some embodiments, the width of the first groove 132a is different from the width of the second groove 134a.

[0085] The width of the first groove 132a and the width of the second groove 134a are different. The width of the first groove 132a can be greater than the width of the second groove 134a, or the width of the second groove 134a can be greater than the width of the first groove 132a. The difference in width between the first groove 132a and the second groove 134a allows the first cutting blade 132 to move relative to the second cutting blade 134 in different spaces when cooperating with different second cutting blades 134. This, in turn, results in different amounts of entangled material being cut between the same first cutting portion 132c and different second cutting portions 134c. The greater the amount of entangled material, the greater the reaction force acting on the first cutting portion 132c and the second cutting portion 134c. The amount of winding material cut between the same first cutting portion 132c and different second cutting portions 134c is different, so that the same first cutting portion 132c is subjected to different reaction forces when cooperating with different second cutting portions 134c, thereby avoiding the same first cutting portion 132c or the same second cutting portion 134c always being subjected to a larger reaction force, reducing the risk of damage to the first cutting portion 132c and the second cutting portion 134c, and improving the service life of the first cutting knife 132 and the second cutting knife 134.

[0086] In some embodiments, the corresponding first grooves 132a and second grooves 134a are at least partially overlapped to form an overlapping area, and the widths of two adjacent overlapping areas are different.

[0087] The widths of two adjacent overlapping areas are different. Alternatively, the overlapping areas may gradually decrease along the moving direction of the first cutting blade 132 , or the overlapping areas may first decrease and then increase.

[0088] The different overlapping areas of the first slot 132a and the second slot 134a result in different spaces between adjacent overlapping areas for accommodating windings. This means that the adjacent overlapping areas can accommodate different amounts of windings, resulting in different amounts of windings cut between the same first cutting portion 132c and different second cutting portions 134c. Because the greater the amount of windings, the greater the reaction force experienced by the first cutting portion 132c and the second cutting portion 134c. The different amounts of windings cut between the same first cutting portion 132c and different second cutting portions 134c result in different reaction forces experienced by the same first cutting portion 132c when engaged with different second cutting portions 134c. This prevents the same first cutting portion 132c or the same second cutting portion 134c from being consistently subjected to a large reaction force, reduces the risk of damage to the first and second cutting portions 132c, 134c, and increases the service life of the first and second cutting blades 132, 134.

[0089] See also Figure 8 , Figure 8 A schematic diagram showing the internal structure of the cleaning roller brush 100 is shown. Figure 8 As shown, the housing 110 is provided with an accommodating cavity 113 and a cutting groove 114 communicating with the accommodating cavity 113 . The cutting member 130 is installed in the accommodating cavity 113 , and at least a portion of the cutting member 130 is exposed in the cutting groove 114 .

[0090] The cleaning strip 120 is arranged outside the shell 110, that is, outside the accommodating cavity 113, and the cutting piece 130 is installed inside the accommodating cavity 113, so that the shell 110 can play a certain protective role for the cutting piece 130 and can minimize the damage of the external structure to the cutting piece 130.

[0091] In addition, the cutting member 130 is installed inside the accommodating cavity 113, so that the space outside the shell 110 is not occupied, making the structure of the entire cleaning roller brush 100 more compact without increasing the diameter of the cleaning roller brush 100.

[0092] The fact that at least a portion of the cutting member 130 is exposed outside the cutting groove 114 means that at least a portion of the first cutting blade 132 and the second cutting blade 134 can be exposed outside the cutting groove 114. The first cutting blade 132 and the second cutting blade 134 can be entirely extended from the cutting groove 114 outside the accommodating cavity 113, or they can be partially extended from the cutting groove 114 outside the accommodating cavity 113. Since the winding material is wound around the outer circumference of the housing 110, the first cutting blade 132 and the second cutting blade 134 extending from the cutting groove 114 outside the accommodating cavity 113 facilitates cutting of the winding material on the outer circumference, thereby effectively cutting the winding material.

[0093] See also Figure 9 , Figure 9 Shown Figure 2 A partial enlarged view of the middle A. Figure 9 As shown, the same cutting groove 114 has multiple sub-grooves 114a arranged at intervals, that is, it can be considered that the same cutting groove 114 is divided into multiple sub-grooves 114a at intervals, and the width of each sub-groove 114a is smaller than the width of the cutting groove 114, that is, the width of a single sub-groove 114a is relatively small, which can prevent larger external impurities from entering the accommodating cavity 113 to a certain extent, and play a certain protective role.

[0094] In the extension direction of the housing 110 (i.e., in the length direction of the housing 110), the first cutting portion 132c and the second cutting portion 134c of each cutting member 130 are installed in the corresponding cutting groove 114 and cut the corresponding area of ​​the cutting groove 114. The partial sub-grooves 114a of the cutting grooves 114 of the two adjacent cutting members 130 are located on the same circumference (e.g., Figure 2 and Figure 3 In the cleaning roller brush 100 shown, two adjacent cutting pieces 130 are two first cutting pieces 130a of different groups, or two first cutting pieces 130a and second cutting pieces 130b of different groups, or two second cutting pieces 130b of different groups. Figure 4 and Figure 5 In the cleaning roller brush shown, the two adjacent cutting pieces 130 are the first cutting piece 130a of the same group or the two second cutting pieces 130b of the same group, or the first cutting piece 130a and the second cutting piece 130b of different groups), which means that the cutting areas of the two adjacent cutting pieces 130 partially overlap, that is, the multiple cutting pieces 130 can basically completely cover the entire shell 110, avoiding the occurrence of cutting blind spots as much as possible, thereby improving the cleaning effect of the entangled objects, and further improving the cleaning effect of the cleaning roller brush 100.

[0095] In addition, since the second cutting knife 134 has multiple second grooves 134a, and the second cutting knife 134 is fixed inside the accommodating cavity 113, the second groove 134a can be connected to the sub-groove 114a and arranged accordingly, that is, the multiple second cutting parts 134c and the multiple sub-grooves 114a are staggered, so that the winding can fall into the second groove 134a through the sub-groove 114a. When cutting, the winding is cut as much as possible below the first cutting part 132c and the second cutting part 134c, which can increase the force applied to the winding and thereby improve the cutting effect.

[0096] In some embodiments, a mounting portion 116 is protruding from the housing 110, and a cutting slot 114 is provided on the mounting portion 116. Since the winding material is wound around the outer surface of the housing 110, the cutting slot 114 is provided on the mounting portion 116 protruding from the housing 110, so that the first cutting member 130 and the second cutting member 130 can extend from the outer surface of the housing 110, that is, the first cutting portion 132c and the second cutting portion 134c can protrude from the outer surface of the housing 110, that is, they can protrude from the winding position of the winding material, so that the first cutting portion 132c and the second cutting portion 134c can cut the winding material.

[0097] The mounting portion 116 is primarily used to accommodate the first cutting portion 132c and the second cutting portion 134c. The shape of the mounting portion 116 can be adapted to the shapes of the first cutting portion 132c and the second cutting portion 134c. Since the first cutting portion 132c and the second cutting portion 134c are generally elongated, the mounting portion 116 can be configured in an elongated shape to accommodate the cutting portions while minimizing the overall dimensions.

[0098] In some embodiments, the height of the mounting portion 116 protruding from the housing 110 is less than the height of the cleaning strip 120 protruding from the housing 110. The cleaning strip 120 is primarily used to clean the surface to be cleaned. If the height of the mounting portion 116 protruding from the housing 110 is greater than the height of the cleaning strip 120 protruding from the housing 110, the mounting portion 116 may contact the surface to be cleaned during the rotation of the housing 110, preventing the cleaning strip 120 from contacting and cleaning the surface to be cleaned.

[0099] The height of the mounting portion 116 protruding from the housing 110 is less than the height of the cleaning bar 120 protruding from the housing 110, which may prevent the cleaning bar 120 from interfering with the floor during cleaning, causing the cleaning bar 120 to fail to clean the floor normally.

[0100] The above describes the specific structure of the cutting member 130 and how the cutting member 130 is installed on the housing 110. The following describes how the cutting member 130 cuts entangled objects such as hair in conjunction with the structure of the transmission member 140.

[0101] See also Figure 10 , Figure 10 The figure shows a schematic diagram of the internal structure of the cleaning roller brush 100. In some embodiments, the cleaning roller brush 100 further includes a transmission member 140 and a connecting member 150. The transmission member 140 is connected to the cutting member 130 for driving the cutting member 130 to reciprocate relative to the housing 110. The connecting member 150 connects two adjacent cutting members 130. Since there are multiple cutting members 130, the connecting member 150 and the transmission member 140 can cooperate to enable one transmission member 140 to drive multiple cutting members 130 to reciprocate relative to the housing 110, thereby reducing the number of transmission members 140, saving the internal space of the housing 110, and miniaturizing the cleaning roller brush 100.

[0102] The transmission member 140 is in transmission connection with the first cutting blade 132 and is used to drive the first cutting blade 132 to reciprocate relative to the housing 110, so that the first cutting blade 132 cooperates with the second cutting blade 134 twice during one movement, which can improve the efficiency of cutting the winding material.

[0103] The transmission member 140 is mounted on the housing 110. The transmission member 140 and the housing 110 do not move, and the transmission member 140 and the housing 110 can be considered as a whole. During the rotation of the housing 110, the transmission member 140 rotates along with the housing 110. The rotation of the housing 110 can drive the rotation of the transmission member 140, without the need to set up a separate driving mechanism to drive the rotation of the transmission member 140. This reduces the number of parts of the cleaning roller brush 100 and can reduce the cost of the cleaning roller brush 100 to a certain extent. At the same time, since there is no need to set up a separate driving mechanism for the transmission member 140, there is no need to reserve a mounting position on the housing 110, which can also reduce the volume of the entire cleaning roller brush 100.

[0104] During the rotation of the housing 110, the transmission member 140 will rotate simultaneously with the housing 110. That is, when the housing 110 starts to rotate, the transmission member 140 will drive the cutting member 130 to rotate. That is, when the cleaning strip 120 on the housing 110 starts to clean the floor, the transmission member 140 will drive the cutting member 130 to rotate, thereby cutting the entangled objects. In other words, when the cleaning roller brush 100 starts cleaning, the cutting member 130 will rotate. If there are entangled objects wrapped around the housing at the same time, the cutting member 130 will be able to cut the entangled objects in time, and there will basically be no situation where a lot of entangled objects on the housing 110 affect the cleaning effect.

[0105] In addition, since the cutting piece 130 will continue to rotate during the rotation of the shell 110, if there is a winding material wrapped around the shell 110, the cutting piece 130 will cut the winding material, and the winding material will be cut as it is wrapped, that is, the winding material will be cut when the number is small. Since the number of winding materials is small, the cutting piece 130 will be easier to cut, and the wear on the cutting piece 130 can also be reduced, thereby increasing the service life of the cutting piece 130.

[0106] See also Figure 11 , Figure 11 Shown Figure 10 A partial enlarged view of point D in the middle. To improve the stability of the reciprocating motion of the first cutting member 130, one of the first cutting blade 132 and the housing 110 may be provided with a guide groove 132e, and the other may be provided with a guide member 119, with the guide member 119 extending through the guide groove 132e. Alternatively, the housing 110 may be provided with the guide groove 132e, and the first cutting blade 132 may be provided with the guide member 119. Alternatively, the housing 110 may be provided with the guide member 119, and the first cutting blade 132 may be provided with the guide groove 132e.

[0107] See also Figure 12 , Figure 12 Shown Figure 10 A partial enlarged view of point C in the middle. The connecting member 150 includes a connecting rod 152 and at least two engaging portions 154. The engaging portions 154 are provided on the connecting rod 152 and engage with the first cutting member 130. The connecting member 150 can connect two or three first cutting members 130. Similarly, the two ends of the same cutting member 130 can also engage with two connecting members 150, respectively.

[0108] Specifically, a clamping segment 132 d may be provided on the first cutting blade 132 , and a clamping slot 156 may be provided on the clamping portion 154 , so that the clamping portion 154 and the first cutting blade 132 are fixed together by the clamping segment 132 d and the clamping slot 156 .

[0109] In some embodiments, the transmission member 140 is disposed between two adjacent cutting members 130 along the extension direction of the housing 110. Since multiple cutting members 130 are driven by a single transmission member 140, the longer the transmission path, the greater the loss of driving force. Since there are multiple cutting members 130 on both sides of the housing 110, the transmission member 140 can be disposed between any two cutting members 130, so that the transmission member 140 is disposed as close as possible to the middle position of the housing 110. During the transmission process through the connecting member 150, the driving force of the cutting members 130 at both ends of the transmission member 140 can be roughly the same, thereby avoiding a large difference in the driving force of the cutting members 130 at the two axial ends of the housing 110, which may result in the cutting member 130 at one end being unable to cut the object to be cut.

[0110] See also Figure 13 , Figure 13 A schematic diagram showing the internal structure of the cleaning roller brush 100 is shown. Figure 13 As shown, the transmission member 140 may include a transmission shaft 142, a deceleration part 144 and a transmission part 147. The transmission shaft 142 is installed on the housing 110. The transmission shaft 142, the deceleration part 144 and the transmission part 147 are sequentially connected in transmission. The transmission part 147 is connected in transmission to the cutting member 130.

[0111] The transmission shaft 142 can be installed on the shell 110 and be connected to the deceleration part 144, the deceleration part 144 is connected to the transmission part 147, and the transmission part 147 is connected to the cutting piece 130. In the process of the transmission shaft 142 following the rotation of the shell 110, the transmission shaft 142 will drive the deceleration part 144 to rotate. After the deceleration part 144 decelerates, the first cutting knife 132 is driven to reciprocate relative to the shell 110 through the transmission part 147.

[0112] Since the overall rotation speed of the cleaning roller brush 100 is relatively high, the first cutting blade 132 also maintains a relatively high rotation speed, which causes the first cutting blade 132 and the second cutting blade 134 to cut the entangled material more frequently, resulting in the first cutting blade 132 and the second cutting blade 134 cutting the entangled material more frequently, causing the first cutting blade 132 and the second cutting blade 134 to wear easily. By providing the speed reduction unit 144, the speed reduction unit 144 cooperates with the transmission shaft 142 and the transmission unit 147 to reduce the rotation speed of the first cutting blade 132, thereby reducing the number of cuts made by the first cutting blade 132 and the second cutting blade 134, thereby reducing the wear of the first cutting blade 132 and the second cutting blade 134, thereby increasing the service life of the first cutting blade 132 and the second cutting blade 134.

[0113] Among them, since the connecting member 150 needs to connect multiple cutting members 130, the connecting member 150 may occupy a large space in the housing 110. The connecting member 150 can be sleeved on the transmission shaft 142 to reduce the overall occupied space.

[0114] See also Figure 14 , Figure 14 The schematic diagram of the structure of the transmission member 140 is shown. The transmission member 140 includes a mounting shell 148, a speed reduction unit 144 is disposed within the mounting shell 148, and a transmission unit 147 and a transmission shaft 142 are mounted outside the mounting shell 148. The speed reduction unit 144 may have various structures. The speed reduction unit 144 may be disposed within the mounting shell 148 so that the entire speed reduction unit 144 forms an integral unit. After assembly, the speed reduction unit 144 can be directly assembled with other components, thereby reducing the assembly process of the entire cleaning roller brush 100.

[0115] In addition, the transmission part 147 is in transmission connection with the cutting member 130. The transmission part 147 can directly cooperate with one of the cutting members 130, and drive the other first cutting members 130 to move through the cooperation between the first cutting member 130 and the connecting member 150. Alternatively, the transmission part 147 can cooperate with the connecting member 150, and drive multiple cutting members 130 to cooperate through the connecting member 150.

[0116] See also Figure 15 , Figure 15 Shown Figure 10 A partial enlarged view of point E in the middle. Specifically, the connecting member 150 may be provided with a transmission groove 157 arranged along one radial direction of the housing 110, and a portion of the transmission portion 147 extends into the transmission groove 157. When the speed reduction portion 144 drives the transmission portion 147 to rotate, the transmission portion 147 cooperates with the transmission groove 157, allowing the connecting member 150 to reciprocate in the axial direction of the housing 110, thereby driving the first cutting blade 132 to reciprocate in the axial direction of the housing 110.

[0117] As for the specific structure of the speed reduction part 144, it can be varied. Two implementation methods are listed below. One is through the turbine 145a and the worm 145b. Figure 16 and Figure 17 As shown, the other is realized by planetary gears, such as Figure 18 and Figure 19 shown.

[0118] See also Figure 16 and Figure 17 , Figure 16 Schematic diagram showing the internal structure of the deceleration unit 144, Figure 17 Shown Figure 16 The deceleration unit 144 may include a turbine 145a and a worm 145b. The turbine 145a is connected to the transmission unit 147, and the worm 145b is in driving connection with the transmission shaft 142.

[0119] Each rotation of the worm 145b causes the turbine 145a to rotate one tooth. The number of teeth on the turbine 145a can be adjusted based on the actual reduction ratio. A greater number of teeth on the turbine 145a results in a greater reduction ratio, while a smaller number of teeth on the turbine 145a results in a smaller reduction ratio. Alternatively, an external gear 142c can be provided on the transmission shaft 142, and an internal gear 145c can be provided at one end of the worm 145b. The number of teeth on the internal gear 145c is greater than that on the external gear 142c, thereby also achieving a certain degree of reduction.

[0120] See also Figure 18 and Figure 19 , Figure 18 and Figure 19 FIG. 1 shows another structural diagram of the deceleration unit 144. Figure 18 and Figure 19 As shown, the reduction unit 144 may include a planetary gear reducer. A planetary gear reducer may be configured with one or more stages. The more stages, the greater the reduction ratio. The number of stages of the planetary gear reducer can be set according to the reduction requirements. For ease of description, the second-stage planetary gear 146e is used as an example. Other stages can be analogously applied.

[0121] The planetary gear reducer includes a primary sun gear 146a, a primary planet gear 146b, a secondary sun gear 146d, a secondary planet gear 146e, a primary planet carrier 146c, and a secondary planet carrier 146f. The primary sun gear 146a is engaged with the primary planet gear 146b, the secondary sun gear 146d is engaged with the secondary planet gear 146e, the primary sun gear 146a is matched with the transmission shaft 142, the primary planet carrier 146c is transmission-connected to the primary planet gear 146b and the secondary sun gear 146d, the secondary planet gear 146e is connected to the secondary planet carrier 146f, and the secondary planet carrier 146f is transmission-connected to the transmission part 147.

[0122] It should be noted that no matter how many stages of planetary gears are provided, the sun gears of the first stage are connected to the transmission shaft 142 , and the planetary gears of the last stage are connected to the transmission part 147 .

[0123] In addition, a first bevel gear 146g can be provided at one end of the secondary planetary carrier 146f away from the secondary planetary gear 146e, and the gear shaft of the first bevel gear 146g is fixedly connected to the secondary planetary carrier 146f. A second bevel gear 147a can also be provided on the transmission part 147, and the first bevel gear 146g is meshed with the second bevel gear 147a. The number of teeth of the first bevel gear 146g is less than the number of teeth of the second bevel gear 147a, and a certain degree of speed reduction can also be achieved.

[0124] See also Figure 20 , Figure 20 A cross-sectional view of the cleaning roller brush 20 is shown. The cleaning roller brush 100 further includes a fixed portion 160 and a movable portion 170. The fixed portion 160 and the movable portion 170 are respectively arranged at opposite ends of the shell. The fixed portion 160 is transmission-connected to the driving mechanism, and the movable portion 170 is rotationally connected to the main body.

[0125] See also Figure 21 , Figure 21 Shown Figure 20 The movable portion 170 includes a core shaft 172 and a bearing sleeve 174 . The core shaft 172 is fixedly connected to the main body. The bearing sleeve 174 is disposed between the core shaft 172 and the main body 22 , so that the housing 110 can rotate relative to the main body 22 .

[0126] Based on the same inventive concept, the present invention 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.
