Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a roller brush assembly and a cleaning device. Background Technology

[0002] Cleaning equipment typically has cleaning functions such as washing, sweeping, and mopping, and can replace users in cleaning tasks such as washing floors, bringing many conveniences to users and thus being widely used.

[0003] Cleaning equipment typically uses roller brushes for cleaning. During the cleaning process, roller brushes easily become entangled with a large amount of hair, reducing their cleaning effectiveness and often requiring manual intervention to remove the hair. In particular, manual hair removal can be difficult in certain areas, necessitating the use of specialized cleaning tools, which is extremely inconvenient for manual cleaning.

[0004] Existing anti-tangling designs for cleaning equipment suffer from problems such as complex structure, high manufacturing cost, difficulty in maintenance, and significant safety hazards. Summary of the Invention

[0005] The main objective of this application is to provide a roller brush assembly and cleaning device that are simple in structure, low in manufacturing cost, easy to maintain, and highly safe.

[0006] In a first aspect, embodiments of this application provide a roller brush assembly for cleaning equipment, comprising:

[0007] A roller brush includes a roller brush shaft and a cleaning strip connected to the roller brush shaft. The cleaning strip has cleaning edges distributed in the axial direction of the roller brush shaft, and the distance between the cleaning edges and the roller brush shaft is a first distance.

[0008] A roller brush cover, wherein the roller brush cover is provided with a suction port facing the roller brush;

[0009] A cutting element is protruding from the inner edge of the suction port of the roller brush cover. The cutting edge of the cutting element faces the opposite direction to the rotation direction of the roller brush, and the distance between the cutting edge of the cutting element and the roller brush axis is a second distance, wherein the second distance is less than the first distance.

[0010] Furthermore, the roller brush cover has a top guide rib and a bottom guide rib on the inner side of the suction port. The top guide rib interferes with the cleaning strip of the roller brush. The bottom guide rib is located below the top guide rib. The direction of the notch formed by the bottom guide rib and the top guide rib is opposite to the rotation direction of the roller brush. The cutting element is located on the bottom guide rib and within the notch formed by the top guide rib and the bottom guide rib, for cutting the entanglement wrapped around the cleaning strip.

[0011] Furthermore, there are multiple top guide ribs, bottom guide ribs, and cutting components. Each top guide rib, bottom guide rib, and cutting component forms a cutting assembly. Multiple cutting assemblies are spaced apart and arranged inside the suction port of the roller brush cover.

[0012] Furthermore, the cutting edge of the cutting element is set at an obtuse angle to the bottom guide rib, and both the top guide rib and the bottom guide rib extend along the tangential direction of the roller brush axis.

[0013] Furthermore, a gap is provided between the bottom guide rib and the roller brush shaft, and the width of the gap is 0.3 to 0.5 mm.

[0014] Furthermore, the top guide rib includes a connecting portion and a guiding portion, the guiding portion being connected to the end of the connecting portion, the guiding portion being V-shaped in the rotation direction of the roller brush shaft, and the bottom guide rib being located below the guiding portion of the top guide rib.

[0015] Furthermore, the roller brush cover includes a first horizontal edge, a second horizontal edge, and a side edge. The first horizontal edge and the second horizontal edge are arranged opposite to each other and connected by the side edge to enclose and form the suction port. The top guide rib is disposed between the first horizontal edge and the second horizontal edge. One end of the connecting portion of the top guide rib is connected to the first horizontal edge, one end of the guiding portion of the top guide rib is connected to the second horizontal edge, and the end of the bottom guide rib is connected to the second horizontal edge.

[0016] Furthermore, the cutting element is triangular in shape, and the cutting element also includes a short side and a long side. The short side and the long side are connected to the cutting edge of the cutting element in pairs. The long side is disposed on the bottom guide rib, and the short side is disposed on the second horizontal side.

[0017] Furthermore, the guide portion of the top guide rib forms a triangular through hole with the second transverse side, and the size of the through hole in any direction is less than or equal to 10 mm.

[0018] Secondly, this application provides a cleaning device including a roller brush assembly as described in any of the above.

[0019] In the roller brush assembly provided in this application embodiment, a cutting element protrudes from the inner edge of the suction port of the roller brush cover. The cutting edge of the cutting element faces the opposite direction to the rotation direction of the roller brush. When the roller brush moves the wrapped material, the cutting edge of the cutting element cuts the wrapped material, which is then sucked away by the fan. This prevents the roller brush from getting tangled and stuck or from the wrapped material entering the gearbox. Furthermore, the cleaning strip of the roller brush has cleaning edges distributed in the axial direction of the roller brush shaft. The distance between the cleaning edge and the roller brush shaft is a first distance, and the distance between the cutting edge of the cutting element and the roller brush shaft is a second distance. The second distance is smaller than the first distance, thereby ensuring that the wrapped material on the roller brush can be cut. Compared with existing anti-tangling solutions, the roller brush assembly provided in this application embodiment has a simple structure, low manufacturing cost, is easy to maintain, and has high safety.

Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0034] This application provides a roller brush assembly and a cleaning device, which are described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0035] In existing technologies, cleaning equipment typically uses roller brushes for cleaning. However, roller brushes are prone to getting tangled with a large amount of hair during the cleaning process, leading to a decrease in their cleaning effectiveness. Excessive hair tangling at both ends of the roller brush will trigger an alarm, often requiring manual intervention to remove the hair. In particular, manual hair removal can be difficult in certain areas, requiring specialized cleaning tools, which is extremely inconvenient for manual cleaning.

[0036] It should be noted that the cleaning equipment provided in this application embodiment can be a cleaning robot with cleaning functions such as washing, sweeping, and mopping. The cleaning equipment can automatically move on the surface to be cleaned to perform cleaning work. Of course, the cleaning equipment can also be a handheld floor scrubber with cleaning functions such as washing, sweeping, and mopping. The user holds the cleaning equipment and pushes it to move on the surface to be cleaned to perform cleaning work, which is not limited here. The following description uses a cleaning robot as an example for the purpose of discussion only and does not constitute a limitation. The surface to be cleaned can be the ground or the surface of an object to be cleaned.

[0037] Therefore, refer to Figures 1 to 3 This application provides a roller brush assembly 100 for a cleaning device 10. The roller brush assembly 100 includes a roller brush 101, a roller brush cover 102, and a cutting member 103. The roller brush 101 includes a roller brush shaft 111 and a cleaning strip 112 connected to the roller brush shaft 111. The cleaning strip 112 has cleaning edges distributed in the axial direction of the roller brush shaft 111, and the distance between the cleaning edges and the roller brush shaft 111 is a first distance. The roller brush cover 102 has a suction port 121 facing the roller brush 101. The cutting member 103 protrudes from the inner edge of the suction port 121 of the roller brush cover 102. The cutting edge 131 of the cutting member 103 faces the opposite direction to the rotation direction of the roller brush 101, and the distance between the cutting edge 131 of the cutting member 103 and the roller brush shaft 111 is a second distance, wherein the second distance is less than the first distance.

[0038] Specifically, when the roller brush assembly 100 provided in this application embodiment is working, the roller brush shaft 111 of the roller brush 101 will drive the cleaning strip 112 to rotate, thereby cleaning the surface to be cleaned. When there are hair or other tangled objects on the surface to be cleaned, some of the tangled objects will be sucked in through the suction port 121 of the roller brush cover 102 and wrapped around the roller brush 101. Since the air pressure of the fan is strongest in the middle of the roller brush 101 and gradually decreases towards both ends, and the V-shaped structure of the roller brush 101 will gather the debris from both ends to the middle, most of the hair and other tangled objects will start to wrap around in the middle. When the tangled objects wrap around in the middle to a certain extent, they will move towards both ends. As more and more tangled objects accumulate, it will cause the roller brush 101 to become stuck at both ends or even cause the gearbox to fail. Because the cutting element 103 protrudes from the inner edge of the suction port 121 of the roller brush cover 102, and the cutting edge 131 of the cutting element 103 faces the opposite direction to the rotation direction of the roller brush 101, when the roller brush 101 moves the wrapped material, the cutting edge 131 of the cutting element 103 will cut the wrapped material. The cut material will be sucked into the dust box by the fan, thus preventing the roller brush 101 from being entangled and jammed or the wrapped material from entering the gearbox. Furthermore, the cleaning strips 112 of the roller brush 101 have cleaning edges distributed in the axial direction of the roller brush shaft 111. The distance between the cleaning edge and the roller brush shaft 111 is a first distance, and the distance between the cutting edge 131 of the cutting element 103 and the roller brush shaft 111 is a second distance, wherein the second distance is smaller than the first distance, thereby ensuring that the wrapped material on the roller brush 101 can be cut. Compared with existing anti-entanglement solutions, the roller brush assembly provided in this embodiment has a simple structure, low manufacturing cost, is easy to maintain, and has high safety.

[0039] It should be noted that the cleaning strip 12 provided in this application embodiment can be at least one of leather strips and brush strips. The roller brush cover 102 of the roller brush assembly 100 provided in this application embodiment is preferably made of plastic and is manufactured by injection molding. The cutting element 103 used in the roller brush assembly 100 of this application embodiment is usually a blade, which is made of metal or plastic, while the cleaning strip 112 of the roller brush 101 is usually made of flexible material, such as plastic.

[0040] Optionally, the cutting element 103 used in the roller brush assembly 100 of this application embodiment can be detachably installed into the notch formed by the bottom guide rib 123 and the top guide rib 122, so that the user can remove the cutting element 103 for cleaning or replace it with a new cutting element 103.

[0041] Furthermore, referring to Figures 3 to 7In some embodiments of this application, the roller brush cover 102 is provided with a top guide rib 122 and a bottom guide rib 123 inside the suction port 121. The top guide rib 122 is interfering with the cleaning strip 112 of the roller brush 101. The bottom guide rib 123 is located below the top guide rib 122. The direction of the notch formed by the bottom guide rib 123 and the top guide rib 122 is opposite to the rotation direction of the roller brush 101. The cutting element 103 is provided on the bottom guide rib 123 and located in the notch formed by the top guide rib 122 and the bottom guide rib 123, for cutting the entanglement wrapped around the cleaning strip 112.

[0042] Specifically, such as Figure 1 and Figure 2 As shown, when the roller brush shaft 111 of the roller brush 101 drives the cleaning strip 112 to rotate, it will also drive the entangled material to rotate. The cleaning strip 112 of the roller brush 101 will move towards the bottom guide rib 123. The cleaning strip 112 of the roller brush 101 will be blocked by the top guide rib 122 and the bottom guide rib 123. Since the direction of the notch formed by the bottom guide rib 123 and the top guide rib 122 is opposite to the rotation direction of the roller brush 101, the cutting element 103 is set on the bottom guide rib 123 and located in the notch formed by the top guide rib 122 and the bottom guide rib 123. The hair and other entangled material wrapped on the roller brush 101 will be cut by the cutting element 103 and then sucked away by the fan. Therefore, it can prevent the roller brush 101 from being entangled and jammed or the entangled material from entering the gearbox. Meanwhile, due to the obstruction of the bottom guide rib 123, the cleaning strip 112 on the roller brush 101 will not enter the gap formed by the top guide rib 122 and the bottom guide rib 123, thereby preventing the cleaning strip 112 from being cut off and thus not affecting the cleaning effect of the roller brush 101. The roller brush assembly provided in this application embodiment has a simple structure, low manufacturing cost, is easy to maintain, and has high safety.

[0043] In addition, refer to Figures 1 to 7 In some embodiments of this application, there are multiple top guide ribs 122, bottom guide ribs 123, and cutting elements 103. Each top guide rib 122, bottom guide rib 123, and cutting element 103 forms a cutting assembly. Multiple cutting assemblies are spaced apart and arranged inside the suction port of the roller brush cover 102. Figures 1 to 7 As shown, in the roller brush assembly 100 provided in this application embodiment, there are two top guide ribs 122, two bottom guide ribs 123 and two cutting pieces 103. Each top guide rib 122, one bottom guide rib 123 and one cutting piece 103 constitutes a cutting assembly. The two sets of cutting assemblies are respectively arranged on both sides of the center line of the roller brush cover 102.

[0044] Therefore, when the roller brush assembly 100 provided in this application embodiment is working, the roller brush shaft 111 of the roller brush 101 will drive the cleaning strip 112 to rotate, thereby cleaning the surface to be cleaned. When there are hair or other tangled objects on the surface to be cleaned, some of the tangled objects will be sucked in through the suction port 121 of the roller brush cover 102 and wrapped around the roller brush 101. Since the air pressure of the fan is strongest in the middle of the roller brush 101 and gradually decreases towards both ends, and the V-shaped structure of the roller brush 101 will gather the debris from both ends to the middle, most of the hair and other tangled objects will start to wrap around in the middle. When the tangled objects wrap around to a certain extent in the middle, they will move towards both ends. As more and more tangled objects accumulate, it will cause the roller brush 101 to become stuck at both ends or even cause the gearbox to fail. Since both ends of the roller brush cover 102 are equipped with cutting components, and the cutting element 103 protrudes from the inner edge of the suction port 121 of the roller brush cover 102, the cutting edge 131 of the cutting element 103 faces the opposite direction to the rotation direction of the roller brush 101. When the roller brush 101 drives the wrapped material to move, the cutting edge 131 of the cutting element 103 will cut the wrapped material at both ends. The cut wrapped material will be sucked into the dust box by the fan, thus preventing the roller brush 101 from being entangled and jammed or the wrapped material from entering the gearbox. In addition, the cleaning strip 112 of the roller brush 101 has cleaning edges distributed in the axial direction of the roller brush shaft 111. The distance between the cleaning edge and the roller brush shaft 111 is a first distance, and the distance between the cutting edge 131 of the cutting element 103 and the roller brush shaft 111 is a second distance. The second distance is smaller than the first distance, thereby ensuring that the wrapped material on the roller brush 101 can be cut. Compared with existing anti-tangling solutions, the roller brush assembly provided in this application embodiment has a simple structure, low manufacturing cost, easy maintenance and high safety.

[0045] Of course, in some embodiments of this application, the number of top guide ribs 122, bottom guide ribs 123, and cutting components 103 can be three or more, that is, the number of cutting components can be three or more sets. Multiple sets of cutting components form a comb-like structure, which can comb and cut the hair and other tangled objects wrapped on the roller brush 101, thus ensuring that the tangled objects wrapped on the roller brush 101 can be cut, and the roller brush 101 can rotate smoothly to achieve cleaning of the surface to be cleaned.

[0046] In addition, to enhance the strength of the bottom guide rib 123, the roller brush assembly 100 provided in this application embodiment also includes a reinforcing rib, which is disposed below or inside the bottom guide rib 123, thereby ensuring that the base guide rib 123 can be stably formed into the cutting element 103, thereby ensuring that the wrapped material can be cut by the cutting element 103.

[0047] Furthermore, referring to Figure 3 and Figure 7In some embodiments of this application, the cutting edge 131 of the cutting member 103 is set at an obtuse angle to the bottom guide rib 123, thereby increasing the cutting stroke of the cutting edge 131, ensuring that hair and other entangled objects can be cut off, and will not get stuck between the cutting edge 131 and the bottom guide rib 123. This can prevent the roller brush 101 from being entangled and stuck or the entangled objects from entering the gearbox.

[0048] Therefore, when the roller brush assembly 100 provided in this application embodiment is working, the roller brush shaft 111 of the roller brush 101 will drive the cleaning strip 112 to rotate, thereby cleaning the surface to be cleaned. When there are hair or other tangled objects on the surface to be cleaned, some of the tangled objects will be sucked in through the suction port 121 of the roller brush cover 102 and wrapped around the roller brush 101. Since the air pressure of the fan is strongest in the middle of the roller brush 101 and gradually decreases towards both ends, and the V-shaped structure of the roller brush 101 will gather the debris from both ends to the middle, most of the hair and other tangled objects will start to wrap around in the middle. When the tangled objects wrap around to a certain extent in the middle, they will move towards both ends. As more and more tangled objects accumulate, it will cause the roller brush 101 to become stuck at both ends or even cause the gearbox to fail. Because the cutting element 103 protrudes from the inner edge of the suction port 121 of the roller brush cover 102, and the cutting edge 131 of the cutting element 103 faces the opposite direction to the rotation direction of the roller brush 101, and the cutting edge 131 of the cutting element 103 is set at an obtuse angle with the bottom guide rib 123, when the roller brush 101 moves the wrapped material, the cutting stroke of the cutting edge 131 of the cutting element 103 is long enough to ensure that the wrapped material is cut. The cut wrapped material is sucked into the dust box by the fan, thus preventing the roller brush 101 from being entangled and jammed or the wrapped material from entering the gearbox. Furthermore, the cleaning strip 112 of the roller brush 101 has cleaning edges distributed in the axial direction of the roller brush shaft 111. The distance between the cleaning edge and the roller brush shaft 111 is a first distance, and the distance between the cutting edge 131 of the cutting element 103 and the roller brush shaft 111 is a second distance, wherein the second distance is smaller than the first distance, thereby ensuring that the wrapped material on the roller brush 101 can be cut. Compared with existing anti-tangling solutions, the roller brush assembly provided in this application embodiment has a simple structure, low manufacturing cost, easy maintenance and high safety.

[0049] Furthermore, refer to again Figure 3 and Figure 7In some embodiments of this application, the top guide rib 122 and the bottom guide rib 123 both extend along the tangential direction of the roller brush shaft 111 of the roller brush 101. Therefore, when the roller brush shaft 111 of the roller brush 101 drives the cleaning strip 112 to rotate, the cleaning strip 112 will not be affected by the resistance of the top guide rib 122 and the bottom guide rib 123, thereby ensuring the stable operation of the roller brush 101. At the same time, hair and other entangled materials wrapped on the roller brush shaft 111 and the cleaning strip 112 of the roller brush 101 can smoothly enter the gaps of the top guide rib 122 and the bottom guide rib 123 and be cut off by the cutter 103, thus further preventing the roller brush 101 from being entangled and jammed or the entangled materials from entering the gearbox.

[0050] Therefore, when the roller brush assembly 100 provided in this application embodiment is working, the roller brush shaft 111 of the roller brush 101 will drive the cleaning strip 112 to rotate, thereby cleaning the surface to be cleaned. When there are hair or other tangled objects on the surface to be cleaned, some of the tangled objects will be sucked in through the suction port 121 of the roller brush cover 102 and wrapped around the roller brush 101. Since the air pressure of the fan is strongest in the middle of the roller brush 101 and gradually decreases towards both ends, and the V-shaped structure of the roller brush 101 will gather the debris from both ends to the middle, most of the hair and other tangled objects will start to wrap around in the middle. When the tangled objects wrap around to a certain extent in the middle, they will move towards both ends. As more and more tangled objects accumulate, it will cause the roller brush 101 to become stuck at both ends or even cause the gearbox to fail. Since the cutting element 103 protrudes from the inner edge of the suction port 121 of the roller brush cover 102, the cutting edge 131 of the cutting element 103 faces the opposite direction to the rotation direction of the roller brush 101, the cutting edge 131 of the cutting element 103 is set at an obtuse angle with the bottom guide rib 123, and both the top guide rib 122 and the bottom guide rib 123 extend along the tangential direction of the roller brush axis 111 of the roller brush 101. Therefore, when the roller brush shaft 111 of the roller brush 101 drives the cleaning strip 112 to rotate, the cleaning strip 112 will not be affected by the resistance of the top guide rib 122 and the bottom guide rib 123, thus ensuring the stable operation of the roller brush 101. When the roller brush 101 drives the entangled material to move, the hair and other entangled materials entangled on the roller brush shaft 111 and the cleaning strip 112 of the roller brush 101 can smoothly enter the gap of the top guide rib 122 and the bottom guide rib 123. The cutting edge 131 of the cutting member 103 will cut the entangled material. The cut entangled material will be sucked into the dust box by the fan, thus preventing the roller brush 101 from being entangled and jammed or the entangled material from entering the gearbox. Furthermore, the cleaning strips 112 of the roller brush 101 have cleaning edges distributed in the axial direction of the roller brush shaft 111. The distance between the cleaning edges and the roller brush shaft 111 is a first distance, and the distance between the cutting edge 131 of the cutting member 103 and the roller brush shaft 111 is a second distance, wherein the second distance is less than the first distance, thereby ensuring that the entangled material wrapped around the roller brush 101 can be cut. Compared with existing anti-entanglement solutions, the roller brush assembly provided in this application embodiment has a simple structure, low manufacturing cost, easy maintenance, and high safety.

[0051] Furthermore, referring to Figure 3 In some embodiments of this application, a gap is provided between the bottom guide rib 123 and the roller brush shaft 111 of the roller brush 101, and the width of the gap is 0.3 to 0.5 mm. Therefore, the roller brush assembly 100 provided in this application embodiment, through the above-mentioned arrangement, can ensure that tangled objects such as hair can smoothly enter the gap between the top guide rib 122 and the bottom guide rib 123 and be cut off by the cutter 103, while preventing the cleaning strip 112 from rubbing against the bottom guide rib 123 and producing abnormal noise when rotating.

[0052] Specifically, when the roller brush assembly 100 provided in this application embodiment is working, the roller brush shaft 111 of the roller brush 101 will drive the cleaning strip 112 to rotate, thereby cleaning the surface to be cleaned. When there are hair or other tangled objects on the surface to be cleaned, some of the tangled objects will be sucked in through the suction port 121 of the roller brush cover 102 and wrapped around the roller brush 101. Since the air pressure of the fan is strongest in the middle of the roller brush 101 and gradually decreases towards both ends, and the V-shaped structure of the roller brush 101 will gather the debris from both ends to the middle, most of the hair and other tangled objects will start to wrap around in the middle. When the tangled objects wrap around in the middle to a certain extent, they will move towards both ends. As more and more tangled objects accumulate, it will cause the roller brush 101 to become stuck at both ends or even cause the gearbox to fail. Because the cutting element 103 protrudes from the inner edge of the suction port 121 of the roller brush cover 102, and the cutting edge 131 of the cutting element 103 faces the opposite direction to the rotation direction of the roller brush 101, when the roller brush 101 moves the wrapped material, the cutting edge 131 of the cutting element 103 will cut the wrapped material. The cut material will be sucked into the dust box by the fan, thus preventing the roller brush 101 from being entangled and jammed or the wrapped material from entering the gearbox. In addition, there is a gap between the bottom guide rib 123 and the roller brush shaft 111 of the roller brush 101. The width of the gap is 0.3 to 0.5 mm. This gap is not too wide to prevent hair wrapped on the roller brush shaft 111 and the cleaning strip 112 of the roller brush 101 from not being able to enter the gap between the top guide rib 122 and the bottom guide rib 123. At the same time, the gap is not so narrow as to produce abnormal noise, thereby causing noise pollution and affecting the user experience. Compared with existing anti-tangling solutions, the roller brush assembly provided in this application embodiment has a simple structure, low manufacturing cost, easy maintenance and high safety.

[0053] Furthermore, referring to Figure 4 , Figure 4 This is a schematic diagram of the bottom structure of the brush cover of the brush assembly provided in Embodiment 1 of this application. In some embodiments of this application, the top guide rib 122 includes a connecting portion 124 and a guide portion 125. The guide portion 125 is connected to the end of the connecting portion 124. The guide portion 125 is V-shaped in the rotation direction of the brush shaft 111 of the brush 101. The bottom guide rib 123 is located below the guide portion 125 of the top guide rib 122.

[0054] Specifically, the connecting portion 124 of the top guide rib 122 forms an interference arrangement with the cleaning strip 112 on the roller brush 101. When the roller brush shaft 111 of the roller brush 101 drives the cleaning strip 112 to rotate, the cleaning strip 112 in contact with the connecting portion 124 will rotate along the connecting portion 124. The guide portion 125 is V-shaped in the rotation direction of the roller brush shaft 111 of the roller brush 101, which can ensure that the cleaning strip 112 rotates smoothly without being affected by the resistance of the guide portion 125. The bottom guide rib 123 is located below the guide portion 125 of the top guide rib 122. The guide portion 125 can cover the cutting piece 103 provided on the bottom guide rib 123, thereby preventing the user's fingers from being cut by the cutting piece 103.

[0055] Therefore, when the roller brush assembly 100 provided in this application embodiment is working, the roller brush shaft 111 of the roller brush 101 will drive the cleaning strip 112 to rotate, thereby cleaning the surface to be cleaned. When there are hair or other tangled objects on the surface to be cleaned, some of the tangled objects will be sucked in through the suction port 121 of the roller brush cover 102 and wrapped around the roller brush 101. Since the air pressure of the fan is strongest in the middle of the roller brush 101 and gradually decreases towards both ends, and the V-shaped structure of the roller brush 101 will gather the debris from both ends to the middle, most of the hair and other tangled objects will start to wrap around in the middle. When the tangled objects wrap around to a certain extent in the middle, they will move towards both ends. As more and more tangled objects accumulate, it will cause the roller brush 101 to become stuck at both ends or even cause the gearbox to fail. Since the cutting member 103 is protruding on the inner edge of the suction port 121 of the roller brush cover 102, the cutting edge 131 of the cutting member 103 faces the opposite direction of rotation of the roller brush 101. Therefore, when the roller brush shaft 111 of the roller brush 101 rotates, the cleaning strip 112, which contacts the connecting part 124, will rotate along the connecting part 124. The guide part 125 is V-shaped in the rotation direction of the roller brush shaft 111 of the roller brush 101, so the cleaning strip 112 is not affected by the resistance of the guide part 125, thus ensuring the stable operation of the roller brush 101. When the roller brush 101 moves the wrapped material, the hair and other wrapped material on the roller brush shaft 111 and the cleaning strip 112 can smoothly enter the notches of the top guide rib 122 and the bottom guide rib 123. The cutting edge 131 of the cutting member 103 will cut the wrapped material, and the cut material will be sucked into the dust box by the fan, thus preventing the roller brush 101 from being jammed by the wrapped material or the wrapped material from entering the gearbox. Compared with existing anti-winding solutions, the roller brush assembly provided in this application embodiment has a simple structure, low manufacturing cost, is easy to maintain, and has high safety.

[0056] It should be noted that, Figure 4 The guide portion 125 on the left side shown is triangular, which is a preferred embodiment of this application, relative to... Figure 4 right side or Figure 5 , Figure 6The trapezoidal guide portion 125 and the triangular guide portion 125 provide less resistance to the cleaning strip 112 of the roller brush 101, thereby ensuring the stable operation of the roller brush 101. When the roller brush 101 moves the wrapped material, the hair and other wrapped material wrapped on the roller brush shaft 111 and the cleaning strip 112 can smoothly enter the gap between the top guide rib 122 and the bottom guide rib 123. The cutting edge 131 of the cutting member 103 will cut the wrapped material, and the cut material will be sucked into the dust box by the fan. Therefore, it can prevent the roller brush 101 from being jammed by the wrapped material or the wrapped material from entering the gearbox. Compared with the existing anti-winding solutions, the roller brush assembly provided in this application embodiment has a simple structure, low manufacturing cost, easy maintenance and high safety.

[0057] Furthermore, referring to Figures 4 to 6 In some embodiments of this application, the roller brush cover 102 includes a first horizontal edge 126, a second horizontal edge 127, and a side edge 128. The first horizontal edge 126 and the second horizontal edge 127 are arranged opposite to each other and connected by the side edge 128 to form a suction port 121. A top guide rib 122 is disposed between the first horizontal edge 126 and the second horizontal edge 127. One end of the connecting portion 124 of the top guide rib 122 is connected to the first horizontal edge 126, one end of the guiding portion 125 of the top guide rib 122 is connected to the second horizontal edge 127, and the end of the bottom guide rib 123 is connected to the second horizontal edge 127.

[0058] Specifically, the suction port 121 of the roller brush cover 102 is formed by a first horizontal side 126, a second horizontal side 127, and a side side 128. A top guide rib 122 is disposed between the first horizontal side 126 and the second horizontal side 127. One end of the connecting portion 124 of the top guide rib 122 is connected to the first horizontal side 126, one end of the guiding portion 125 of the top guide rib 122 is connected to the second horizontal side 127, and the end of the bottom guide rib 123 is connected to the second horizontal side 127. Compared to existing solutions, the roller brush assembly provided in this embodiment has a simple structure, low manufacturing cost, is easy to maintain, and has high safety.

[0059] Furthermore, referring to Figure 3 and Figure 7 In some embodiments of this application, the cutting element 103 is triangular and includes a short side 132 and a long side 133. The short side 132 and the long side 133 are connected to the cutting edge 131 of the cutting element 103 in pairs. The long side 133 is disposed on the bottom guide rib 123 and the short side 132 is disposed on the second horizontal side 127.

[0060] Specifically, the long side 133 of the cutting element 103 is embedded in the bottom guide rib 123, while the short side 132 is embedded in the second transverse side 127 of the roller brush cover 102. On the one hand, this ensures that the cutting element 103 is stably set on the bottom guide rib 123, and on the other hand, it ensures the cutting stroke of the blade edge 131, ensuring that hair and other tangled objects can be cut off and will not get stuck between the blade edge 131 and the bottom guide rib 123. Therefore, it can prevent the roller brush 101 from being tangled and stuck or the tangled objects from entering the gearbox.

[0061] Furthermore, referring to Figure 4 In some embodiments of this application, the guide portion 125 of the top guide rib 122 and the second transverse side 127 form a triangular through hole 129, and the size of the through hole 129 in any direction is less than or equal to 10 mm.

[0062] Specifically, since the cutting element 103 is usually quite sharp, the user's fingers may be cut by the cutting element 103 during use. The cutting element 103 is located below the guide portion 125. The guide portion 125 of the top guide rib 122 and the second horizontal side 127 form a triangular through hole 129. The size of the through hole 129 in any direction is less than or equal to 10 mm, thus ensuring that the user's fingers will not pass through the through hole 129, thereby preventing the user's fingers from being cut by the cutting element 103. In other words, the roller brush assembly 100 provided in this application embodiment can further improve the safety of use through the above-mentioned settings.

[0063] It should be noted that, Figure 4 The through hole 129 on the left side is triangular, which is a preferred embodiment of this application. Compared with the trapezoidal through hole 129 on the right side, the guide portion 125 on the left side provides less resistance to the cleaning strip 112 of the roller brush 101, thereby ensuring the stable operation of the roller brush 101. When the roller brush 101 moves the wrapped material, the hair and other wrapped material wrapped on the roller brush shaft 111 and the cleaning strip 112 of the roller brush 101 can smoothly enter the notch between the top guide rib 122 and the bottom guide rib 123. The cutting edge 131 of the cutting member 103 will cut the wrapped material, and the cut material will be sucked into the dust box by the fan. Therefore, it can prevent the roller brush 101 from being jammed by the wrapped material or the wrapped material from entering the gearbox. Compared with the existing anti-winding solutions, the roller brush assembly provided in this application embodiment has a simple structure, low manufacturing cost, easy maintenance and high safety.

[0064] Furthermore, the roller brush assembly 100 provided in this application embodiment also includes a shielding member disposed within the through hole 129, thereby shielding the cutting member 103. This ensures that the user's fingers will not pass through the through hole 129, thus preventing the user's fingers from being cut by the cutting member 103. In other words, the roller brush assembly 100 provided in this application embodiment can further improve the safety of use through the above-mentioned design. Simultaneously, when cleaning the surface to be cleaned, due to the obstruction of the shielding member, carpets and other materials on the surface to be cleaned will not enter the gap between the top guide rib 122 and the bottom guide rib 123, preventing them from being cut. The shielding member can be made of nylon mesh or the like, and the nylon mesh can be disposed within the through hole 129 by die-cutting or secondary molding.

[0065] Reference Figures 1 to 3 This application provides a cleaning device 10, including the roller brush assembly 100 as described above. The specific structure of the roller brush assembly 100 is as described in the above embodiments. Since the roller brush assembly 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0066] like Figures 1 to 7 As shown in the figure, this application embodiment provides a roller brush assembly 100 for cleaning device 10. The roller brush assembly 100 includes a roller brush 101, a roller brush cover 102, and a cutting member 103. The roller brush 101 includes a roller brush shaft 111 and a cleaning strip 112 connected to the roller brush shaft 111. The cleaning strip 112 has cleaning edges distributed in the axial direction of the roller brush shaft 111, and the distance between the cleaning edges and the roller brush shaft 111 is a first distance. The roller brush cover 102 has a suction port 121 facing the roller brush 101. The cutting member 103 protrudes from the inner edge of the suction port 121 of the roller brush cover 102. The cutting edge 131 of the cutting member 103 faces the opposite direction to the rotation direction of the roller brush 101, and the distance between the cutting edge 131 of the cutting member 103 and the roller brush shaft 111 is a second distance, wherein the second distance is less than the first distance.

[0067] Specifically, when the roller brush assembly 100 is working, the roller brush shaft 111 of the roller brush 101 drives the cleaning strip 112 to rotate, thereby cleaning the surface to be cleaned. When there are hair or other tangled objects on the surface to be cleaned, some of the tangled objects will be sucked in through the suction port 121 of the roller brush cover 102 and wrapped around the roller brush 101. Since the air pressure of the fan is strongest in the middle of the roller brush 101 and gradually decreases towards both ends, and the V-shaped structure of the roller brush 101 will gather the debris from both ends to the middle, most of the hair and other tangled objects will start to wrap around in the middle. When the tangled objects wrap around to a certain extent in the middle, they will move towards both ends. As more and more tangled objects accumulate, it will cause the roller brush 101 to become stuck at both ends or even cause the gearbox to fail. Because the cutting element 103 protrudes from the inner edge of the suction port 121 of the roller brush cover 102, and the cutting edge 131 of the cutting element 103 faces in the opposite direction to the rotation direction of the roller brush 101, when the roller brush 101 moves the wrapped material, the cutting edge 131 of the cutting element 103 will cut the wrapped material, which will then be sucked away by the fan. This prevents the roller brush 101 from being entangled and jammed or from entering the gearbox. Furthermore, the cleaning strip 112 of the roller brush 101 has cleaning edges distributed in the axial direction of the roller brush shaft 111. The distance between the cleaning edge and the roller brush shaft 111 is a first distance, and the distance between the cutting edge 131 of the cutting element 103 and the roller brush shaft 111 is a second distance, wherein the second distance is smaller than the first distance, thereby ensuring that the wrapped material on the roller brush 101 can be cut. Compared with existing anti-entanglement solutions, the roller brush assembly provided in this embodiment has a simple structure, low manufacturing cost, is easy to maintain, and has high safety.

[0068] It should be noted that the cleaning equipment provided in this application embodiment can be a cleaning robot with cleaning functions such as washing, sweeping, and mopping. The cleaning equipment can automatically move on the surface to be cleaned to perform cleaning work. Of course, the cleaning equipment can also be a handheld floor scrubber with cleaning functions such as washing, sweeping, and mopping. The user holds the cleaning equipment and pushes it to move on the surface to be cleaned to perform cleaning work. There is no limitation on this.
