Abstract
Description
Technical Field
[0001] This application relates to the field of cleaning technology, and more specifically, to a cleaning organization and cleaning equipment. Background Technology
[0002] Cleaning equipment includes robotic vacuum cleaners, vacuum cleaners, and multi-functional cleaning base stations. Most cleaning equipment is equipped with a cleaning mechanism, which is used to clean up external garbage and collect it into the cleaning equipment.
[0003] Cleaning devices typically consist of a housing and cleaning components, including a roller brush or a drum, which are rotatably mounted on the housing. However, during cleaning, dirt may accumulate on the housing at the end of the cleaning component, reducing the cleaning effectiveness of the device. Utility Model Content
[0004] The main objective of this application is to provide a cleaning mechanism and cleaning equipment to at least solve the problem of decreased cleaning effectiveness of existing cleaning equipment.
[0005] According to one aspect of this application, a cleaning facility is provided, comprising:
[0006] The housing has an installation cavity and a dust suction port communicating with the installation cavity;
[0007] A cleaning component is rotatably disposed in the mounting cavity along its own axis. The cleaning component has a fixed end and a free end disposed opposite to each other along its own axis. The fixed end is used to connect with the housing. The free end includes a first end face. A strip-shaped protrusion is provided on the first end face. The strip-shaped protrusion extends along the direction from the geometric center of the first end face to the edge of the first end face, and the strip-shaped protrusion passes through the geometric center of the first end face. The axis of the cleaning component passes through the geometric center of the first end face.
[0008] Furthermore, the strip-shaped protrusion has a first end and a second end that are disposed opposite to each other along its own extending direction;
[0009] Wherein, along the extension direction of the strip-shaped protrusion itself, the minimum distance L1 between the first end and the outer edge of the first end face is greater than the minimum distance L2 between the second end and the outer edge of the first end face.
[0010] Furthermore, the strip-shaped protrusion has a first end and a second end that are disposed opposite to each other along its own extending direction;
[0011] Along the direction from the first end to the second end, the height of the strip-shaped protrusion protruding from the first end face gradually increases.
[0012] Furthermore, the strip-shaped protrusion has a first end and a second end that are disposed opposite to each other along its own extending direction;
[0013] Wherein, along the extending direction of the strip-shaped protrusion, the minimum distance L1 between the first end and the outer edge of the first end face and the minimum distance L2 between the second end and the outer edge of the first end face satisfy the following relationship: 0.075 ≤ L2 / L1 ≤ 0.385; and / or,
[0014] Along the extending direction of the strip-shaped protrusion, the minimum distance L1 between the first end and the outer edge of the first end face satisfies the following relationship: 2.6mm ≤ L1 ≤ 4.0mm; and / or,
[0015] Along the extending direction of the strip-shaped protrusion, the minimum distance L2 between the second end and the outer edge of the first end face satisfies the following relationship: 0.3mm ≤ L2 ≤ 1.0mm; and / or,
[0016] Along the extending direction of the strip-shaped protrusion, the maximum length L4 of the first end face and the maximum length L3 of the strip-shaped protrusion satisfy the following relationship: 0.538 ≤ L3 / L4 ≤ 0.818; and / or,
[0017] Along the extending direction of the strip-shaped protrusion, the maximum length L4 of the first end face satisfies the relationship: 11mm ≤ L4 ≤ 13mm; and / or,
[0018] Along the extending direction of the strip-shaped protrusion, the maximum length L3 of the strip-shaped protrusion satisfies the relationship: 7mm≤L3≤9mm.
[0019] Furthermore, the strip-shaped protrusion has a first end and a second end that are disposed opposite to each other along its own extending direction;
[0020] Wherein, the minimum height H1 of the first end protruding from the first end face and the maximum height H2 of the second end protruding from the first end face satisfy the relationship: 0.167≤H1 / H2≤0.333; and / or,
[0021] The minimum height H1 of the first end protruding from the first end face satisfies the relationship: 0.5mm ≤ H1 ≤ 1.0mm; and / or,
[0022] The maximum height H2 of the second end protruding from the first end face satisfies the relationship: 2.5mm≤H2≤3.0mm.
[0023] Furthermore, the strip-shaped protrusion includes an interconnected side peripheral surface and a top surface, at least one of the side peripheral surface and the top surface including a smooth arcuate surface.
[0024] Furthermore, at least one of the two sides of the strip-shaped protrusion in the width direction is provided with a concave surface, and the concave surface is recessed in the direction close to the interior of the strip-shaped protrusion.
[0025] Furthermore, a first concave surface and a second concave surface are respectively provided on both sides of the strip-shaped protrusion in the width direction. The first concave surface is recessed in the direction close to the second concave surface, and the second concave surface is recessed in the direction close to the first concave surface.
[0026] The strip-shaped protrusion has a first convex surface and a second convex surface on both sides of its extension direction. The first convex surface is connected to the first side of the first concave surface and the first side of the second concave surface, respectively. The second convex surface is connected to the second side of the first concave surface and the second side of the second concave surface, respectively. The first convex surface protrudes in a direction away from the second convex surface, and the second convex surface protrudes in a direction away from the first convex surface.
[0027] Furthermore, the cleaning mechanism also includes a drive component;
[0028] The fixed end includes a second end face, the suction port is located on the side of the housing near the first end face, and the drive assembly is drivenly connected to the cleaning component and is located on the side of the housing near the second end face.
[0029] This application also provides a cleaning device, which includes the cleaning mechanism described above.
[0030] Compared to existing technologies, the cleaning component of this application has a strip-shaped protrusion on its first end face. When the cleaning component rotates, the strip-shaped protrusion agitates the debris and stains in the mounting cavity corresponding to the end of the cleaning component. Some solid debris or stains adhering to the inner wall of the mounting cavity are loosened by the agitation and then sucked away by the suction port. Furthermore, stains such as hair are agitated and clump together by the strip-shaped protrusion. Because the hair clumps together, the suction area of the suction port for the clumps increases, making it easier to suck away the clumps. In addition, the strip-shaped protrusion extends from the geometric center of the first end face to its edge, and passes through the center of the first end face. The axial direction of the cleaning component also passes through the center of the first end face. This means that the strip-shaped protrusion forms a spiral motion trajectory when rotating, allowing it to handle debris of different particle sizes simultaneously. It is worth noting that existing protrusions are typically cylindrical, and these cylindrical protrusions do not extend to the center of the first end face. This means that the cylindrical protrusions have a limited range for agitating debris or stains, and the cylindrical protrusions cannot effectively agitate debris within the housing relative to the center of the face. Consequently, debris or stains still accumulate in the mounting cavity corresponding to the end of the cleaning component during operation. In other words, with the design of this embodiment, the strip-shaped protrusion provides a higher agitation coverage compared to existing technologies. The strip-shaped protrusion can agitate debris located at different positions in the suction port, thereby improving the cleaning effect of the cleaning component to a certain extent.

Detailed Implementation
[0044] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0045] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0047] It is understood that during the operation of the cleaning equipment, the cleaning mechanism is used to clean the surface to be cleaned. When the cleaning component 20 cleans the surface, some stains or debris may move to the end of the cleaning component 20 and accumulate in the housing 10 corresponding to the end of the cleaning component 20. When the suction port 102 on the housing 10 has a low adsorption force on these stains or debris, the stains or debris will not be sucked away by the suction port 102. When a large amount of stains or debris accumulates on the housing 10, it will affect the rotation speed of the cleaning component 20, thereby affecting the cleaning efficiency of the cleaning equipment on the surface to be cleaned. In severe cases, the stains or debris may jam the cleaning component 20, making the cleaning equipment unable to operate normally.
[0048] To solve the above problems, see Figures 1 to 10 As shown, according to an embodiment of this application, a cleaning device is provided, which includes a cleaning mechanism, the cleaning mechanism including a housing 10 and a cleaning component 20.
[0049] The housing 10 has a mounting cavity 101 and a suction port 102 communicating with the mounting cavity 101. A cleaning component 20 is rotatably disposed in the mounting cavity 101 along its own axis. The cleaning component 20 has a fixed end 22 and a free end 21 disposed opposite to each other along its own axis. The fixed end 22 is used to connect to the housing 10. The free end 21 includes a first end face 211 with a strip-shaped protrusion 30 extending from the geometric center of the first end face 211 to its edge, passing through the geometric center of the first end face 211. The axis of the cleaning component 20 passes through the geometric center of the first end face 211. Specifically, in this embodiment, the cleaning component 20 is a single cantilever cleaning component, meaning the fixed end 22 is used to connect to the housing 10, while the free end 21 is not connected to the housing 10. This arrangement makes it easier for hair or debris on the free end 21 to be ejected from the mounting cavity. Because the first end face 211 of the cleaning component 20 in this embodiment is provided with a strip-shaped protrusion 30, when the cleaning component 20 rotates, the strip-shaped protrusion 30 can agitate the garbage and stains in the mounting cavity 101 corresponding to the end of the cleaning component 20. Some of the solid garbage or stains adhering to the inner wall of the mounting cavity 101 are agitated and loosened, and then sucked away by the suction port 102. For example, stains such as hair are agitated and clump together under the action of the strip-shaped protrusion 30. Since the hair clumps together, the adsorption area of the suction port 102 for the clumps of hair increases, making it easier for the suction port 102 to suck away the clumps of hair. Furthermore, the strip-shaped protrusion 30 extends along the direction from the geometric center of the first end face 211 to the edge of the first end face 211, and the strip-shaped protrusion 30 passes through the center of the first end face 211. The axial direction of the cleaning component 20 also passes through the center of the first end face 211. This means that the strip-shaped protrusion 30 forms a spiral motion trajectory when rotating, allowing it to process waste of different particle sizes simultaneously. It is worth noting that existing protrusions are typically cylindrical, and these cylindrical protrusions do not extend to the center of the first end face 211. This means that the cylindrical protrusions have a small range of agitation for waste or dirt, and the cylindrical protrusions within the housing relative to the center of the surface cannot function effectively. Consequently, waste or dirt still accumulates in the mounting cavity 101 corresponding to the end of the cleaning component 20 during operation. In other words, through the configuration of this embodiment, the strip protrusion 30 has a higher agitation coverage compared to the prior art. The strip protrusion 30 can agitate the garbage located at different positions of the suction port 102, thereby preventing the garbage or stains from jamming the cleaning component 20 to a certain extent.
[0050] Furthermore, the strip-shaped protrusion 30 has a first end 31 and a second end 32 disposed opposite to each other along its own extending direction. Wherein, along the own extending direction of the strip-shaped protrusion 30, the minimum distance L1 between the first end 31 and the outer edge of the first end face 211 is greater than the minimum distance L2 between the second end 32 and the outer edge of the first end face 211.
[0051] Specifically, when L1 is greater than L2 and the cleaning component 20 rotates, the radius of rotation of the first end 31 around the center of the first end face 211 is smaller than the radius of rotation of the second end 32 around the center of the first end face 211. In other words, the agitation range of the first end 31 is smaller, reducing the amount of debris or stains in contact with it. This is to prevent excessive debris or stains from adhering to the first end 31 after agitation. Understandably, because the first end 31 is farther from the suction port 102 than the second end 32, and its radius of rotation is smaller, the torque on the debris or stains adhering to the first end 31 is smaller, making it less likely for debris and stains to fall off. However, after the second end 32 rotates, because it is closer to the suction port 102, the suction port 102 exerts a greater force on the second end 32; simultaneously, the torque on the debris or stains on the second end 32 is greater, making it more difficult for debris or stains to adhere to the second end 32. On the other hand, by asymmetrically setting L1 and L2, the mass distribution at both ends of the strip protrusion 30 passing through the center of the first end face 211 is uneven. That is, when the cleaning part 20 rotates, an eccentric force is generated on the strip protrusion 30, so as to throw the stirred garbage or stains out of the strip protrusion 30. On the one hand, it makes it easier for the suction port 102 to absorb garbage or stains, and on the other hand, it prevents garbage or stains from adhering to the strip protrusion 30.
[0052] Furthermore, along the direction from the first end 31 to the second end 32, the height of the strip-shaped protrusion 30 protruding from the first end face 211 gradually increases.
[0053] In this embodiment, since the height of the strip-shaped protrusion 30 protruding from the first end face 211 gradually increases along the direction from the first end 31 to the second end 32, the second end 32 is more likely to come into contact with the garbage or stains when the strip-shaped protrusion 30 is stirred, while the first end 31 has a smaller contact range with the garbage or stains. This avoids to some extent that the garbage or stains will stick to the first end 31 after it is stirred.
[0054] Furthermore, along the extending direction of the strip protrusion 30, the minimum distance L1 between the first end 31 and the outer edge of the first end face 211 and the minimum distance L2 between the second end 32 and the outer edge of the first end face 211 satisfy the following relationship: 0.075≤L2 / L1≤0.385.
[0055] When the ratio of L1 to L2 satisfies the above relationship, the second end 32 is farther from the center of the first end face 211 and closer to the suction port 102 than the first end 31. This means that when the second end 32 agitates the debris or dirt, it is more easily sucked away by the suction port 102. However, if L2 / L1 is less than 0.075, it means the first end 31 is too close to the center of the first end face 211, resulting in a small radius of rotation around the center of the first end face 211, making it difficult for the first end 31 to agitate the debris or dirt in the opposite mounting cavity 101. If L2 / L1 is greater than 0.385, it means the distance between the first end 31 and the center of the first end face 211 is similar to the distance between the second end 32 and the center of the first end face 211, potentially resulting in a smaller eccentric force on the strip-shaped protrusion 30, leading to a poorer agitation effect on the debris. The values of L2 / L1 can be 0.075, 0.100, 0.150, 0.200, 0.250, 0.300, 0.350 and 0.385.
[0056] Optionally, along the extending direction of the strip protrusion 30, the minimum distance L1 between the first end 31 and the outer edge of the first end face 211 satisfies the relationship: 2.6mm≤L1≤4.0mm.
[0057] Specifically, when the minimum distance L1 between the first end 31 and the outer edge of the first end face 211 is too small, for example, L1 is less than 2.6 mm, this will result in an excessively large radius of rotation of the first end 31 around the center of the first end face 211, increasing the contact area between the first end 31 and the garbage or stains. This may cause more garbage or stains to adhere to the first end 31 when it agitates the garbage or stains. Conversely, if the minimum distance L1 between the first end 31 and the outer edge of the first end face 211 is too large, for example, L1 is greater than 4 mm, this will result in an excessively small radius of rotation of the first end 31 around the center of the first end face 211, resulting in a lower agitation ability of the first end 31 on garbage or stains. The value of L1 can be 2.6 mm, 3.0 mm, 3.5 mm, or 4.0 mm.
[0058] Optionally, along the extending direction of the strip protrusion 30, the minimum distance L2 between the second end 32 and the outer edge of the first end face 211 satisfies the relationship: 0.3mm≤L2≤1.0mm.
[0059] In this embodiment, when L2 is less than 0.3 mm, the second end 32 is too close to the outer edge of the first end face 211. When the second end 32 agitates the hair, the hair may move from the second end 32 to the cleaning component 20, causing the hair to become entangled on the cleaning component 20. When L2 is greater than 1.0 mm, the distance between the second end 32 and the center of the first end face 211 is too close. On the one hand, this results in a smaller agitation range for the strip-shaped protrusion 30. On the other hand, it may also result in a smaller bias force generated on the second end 32 when the cleaning component 20 rotates, thus affecting the agitation effect of the second end 32. The value of L2 can be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, and 1.0 mm.
[0060] Optionally, along the extending direction of the strip protrusion 30, the maximum length L4 of the first end face 211 and the maximum length L3 of the strip protrusion 30 satisfy the following relationship: 0.538≤L3 / L4≤0.818.
[0061] When the ratio of L3 to L4 satisfies the above relationship, the strip protrusion 30 will not be too short relative to the first end face 211, meaning the area of the strip protrusion 30 that can agitate garbage or stains will not be too small; at the same time, the strip protrusion 30 will not be too long relative to the first end face 211, causing hair to potentially cross the strip protrusion 30 and become entangled on the cleaning component 20 when agitating garbage such as hair. The value of L3 / L4 can be 0.538, 0.550, 0.580, 0.600, 0.625, 0.650, 0.675, 0.700, 0.725, 0.750, 0.775, 0.800, and 0.818.
[0062] Optionally, along the extending direction of the strip protrusion 30, the maximum length L4 of the first end face 211 satisfies the relationship: 11mm≤L4≤13mm.
[0063] Understandably, when the maximum length L4 of the first end face 211 is too long, for example, L4 greater than 13mm, this may cause the cleaning component 20 to easily interfere with the inner wall of the mounting cavity 101 when it rotates within the mounting cavity 101. Conversely, when L4 is less than 11mm, it will affect the cleaning efficiency of the cleaning component 20. The value of L4 can be 11mm, 11.5mm, 12mm, 12.5mm, 13mm, 13.5mm, or 14mm.
[0064] Optionally, along the extending direction of the strip protrusion 30, the maximum length L3 of the strip protrusion 30 satisfies the relationship: 7mm≤L3≤9mm.
[0065] Specifically, if L3 is greater than 9mm, the strip-shaped protrusion 30 is too long, which may cause the second end 32 of the strip-shaped protrusion 30 to be too close to the outer edge of the first end face 211. When the second end 32 agitates the hair, the hair may easily cross the strip-shaped protrusion 30 and wrap around the outer peripheral surface of the cleaning component 20. When L3 is less than 7mm, the strip-shaped protrusion 30 is too short, and the range of agitation of debris or stains by the strip-shaped protrusion 30 is reduced, which may still cause a lot of debris to accumulate in the mounting cavity 101. The value of L3 can be 7mm, 7.5mm, 8mm, 8.5mm, and 9mm.
[0066] It is understandable that when the strip-shaped protrusion 30 agitates the garbage or stains, since the radius of rotation of the first end 31 around the center of the first end face 211 is smaller, and the first end 31 is farther from the suction port 102 than the second end 32, it is necessary to avoid agitating too much garbage with the first end 31 to prevent excessive accumulation of garbage on the first end 31. Therefore, in this embodiment, the minimum height H1 of the first end 31 protruding from the first end face 211 and the maximum height H2 of the second end 32 protruding from the first end face 211 satisfy the following relationship: 0.167≤H1 / H2≤0.333.
[0067] In other words, when H1 / H2 satisfies the above relationship, the first end 31 has a certain ability to agitate garbage or stains. However, because the height of the first end 31 protruding from the first end face 211 is lower than the height of the second end 32 protruding from the first end face 211, it will not come into excessive contact with garbage or stains, thus preventing excessive garbage or stains from adhering to the first end 31. When H1 / H2 is less than 0.167, the height of the first end 31 protruding from the first end face 211 is too low compared to the height of the second end 32 protruding from the first end face 211, which may result in the first end 31 being unable to clean the garbage or stains near the center of the first end face 211. When H1 / H2 is greater than 0.333, the amount of contact between the first end 31 and garbage or stains may increase, leading to excessive accumulation of garbage or stains on the first end 31. The value of H1 / H2 can be 0.167, 0.200, 0.230, 0.260, 0.300, and 0.333.
[0068] In some embodiments, the minimum height H1 of the first end 31 protruding from the first end face 211 satisfies the relationship: 0.5mm≤H1≤1.0mm.
[0069] When H1 is greater than 1.0 mm, more debris or stains will come into contact with the first end 31, which may lead to excessive accumulation of debris or stains on the first end 31. When H1 is less than 0.5 mm, the first end 31 may be unable to remove debris near the center of the first end face 211. The value of H1 can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, and 1.0 mm.
[0070] In some embodiments, the maximum height H2 of the second end 32 protruding from the first end face 211 satisfies the relationship: 2.5mm≤H2≤3.0mm.
[0071] When H2 is greater than 3.0 mm, the maximum height of the second end 32 protruding from the first end face 211 is too high, which may cause interference between the second end 32 and the inner wall of the mounting cavity 101 when the cleaning part 20 rotates. When H2 is less than 2.5 mm, the agitation range of the second end 32 for debris or stains will be reduced, which may prevent the debris accumulated in the mounting cavity 101 from being completely removed. The value of H2 can be 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, and 3.0 mm.
[0072] Furthermore, the strip-shaped protrusion 30 includes interconnected side peripheral surfaces and a top surface, at least one of which includes a smooth arcuate surface.
[0073] In one specific embodiment, both the side and top surfaces are smooth arc-shaped surfaces. One purpose of this design is to further prevent garbage or stains from adhering to the strip protrusion 30 when it is agitated. In this embodiment, a smooth arc-shaped surface refers to an arc-shaped surface with a coefficient of friction of less than 0.2. When the coefficient of friction of the arc-shaped surface is less than 0.2, it can effectively prevent, for example, hair or sludge from adhering to the arc-shaped surface.
[0074] In some embodiments, at least one of the two sides of the strip protrusion 30 in the width direction is provided with a concave surface 33, and the concave surface 33 is recessed in the direction close to the interior of the strip protrusion 30.
[0075] Specifically, the concave surface 33 causes the width of the strip-shaped protrusion 30 to first decrease and then increase along the direction from the first end 31 to the second end 32. Furthermore, the strip-shaped protrusion 30 creates redundant space at the position of the concave surface 33. Thanks to this redundant space, the solid waste is less likely to be compressed when the strip-shaped protrusion 30 agitates it, thus facilitating the dispersion of the solid waste under the action of the strip-shaped protrusion 30. On the other hand, the concave surface 33 also has a certain guiding effect, allowing the waste to move along the surface of the concave surface 33 to the end of the strip-shaped protrusion 30.
[0076] In some embodiments, a first concave surface 331 and a second concave surface 332 are respectively provided on both sides of the strip-shaped protrusion 30 in the width direction. The first concave surface 331 is recessed in the direction close to the second concave surface 332, and the second concave surface 332 is recessed in the direction close to the first concave surface 331. A first convex surface 34 and a second convex surface 35 are provided on both sides of the extension direction of the strip-shaped protrusion 30. The first convex surface 34 is connected to the first side of the first concave surface 331 and the first side of the second concave surface 332, respectively. The second convex surface 35 is connected to the second side of the first concave surface 331 and the second side of the second concave surface 332, respectively. The first convex surface 34 protrudes in the direction away from the second convex surface 35, and the second convex surface 35 protrudes in the direction away from the first convex surface 34.
[0077] Specifically, the arrangement of the first concave surface 331 and the second concave surface 332 allows the debris or stains agitated by the strip-shaped protrusion 30 to move along the outer surfaces of the first concave surface 331 and the second concave surface 332 to the first convex surface 34 and the second convex surface 35. When the debris or stains move to the first convex surface 34 and the second convex surface 35, the supporting effect of the first convex surface 34 and the second convex surface 35 on the debris and stains is reduced, and the debris or stains are more likely to fall off the first convex surface 34 and the second convex surface 35. In other words, the arrangement of the first concave surface 331, the second concave surface 332, the first convex surface 34, and the second convex surface 35 in this embodiment allows the debris or stains to be guided to both ends of the strip-shaped protrusion 30, and to a certain extent avoids the accumulation of debris or stains on both ends of the strip-shaped protrusion 30.
[0078] In some embodiments, the cleaning mechanism further includes a drive assembly 40. The fixed end 22 includes a second end face 212, and the suction port 102 is located on the side of the housing 10 near the first end face 211. The drive assembly 40 is drivenly connected to the cleaning component 20 and is located on the side of the housing 10 near the second end face 212. Specifically, when the cleaning device cleans the surface to be cleaned, the debris or stains cleaned by the cleaning component 20 move along the direction from the first end face 211 to the second end face 212, and then some of the debris or stains are sucked away by the suction port 102. Some of the debris moves into the mounting cavity 101 opposite to the first end face 211. Then, this debris is agitated by the strip-shaped protrusion 30 and sucked away by the suction port 102, thereby preventing debris from accumulating in the mounting cavity 101 and jamming the cleaning component 20, ultimately leading to a decrease in the cleaning ability of the cleaning device. Of course, in some embodiments, both the first end face 211 and the second end face 212 may be provided with strip-shaped protrusions 30, and the suction port 102 may also be provided on the housing 10 corresponding to the middle of the cleaning component 20. In this embodiment, the drive assembly 40 includes a drive motor and a gearbox.
[0079] In some embodiments, a plurality of strip-shaped protrusions 30 may be provided on the first end face 211, the plurality of strip-shaped protrusions 30 being arranged circumferentially at intervals along the first end face 211, and the first end 31 of each strip-shaped protrusion 30 being integrally formed.
[0080] Specifically, the arrangement of multiple strip-shaped protrusions 30 is to improve the agitation ability of the strip-shaped protrusions 30. For example, when agitating solid waste, the multiple strip-shaped protrusions 30 can apply force to the solid waste multiple times, thereby enabling the solid waste to disperse quickly.
[0081] In summary, the cleaning mechanism and equipment of this application, by providing a strip-shaped protrusion 30 on the first end face 211 of the cleaning component 20, enable the strip-shaped protrusion 30 to clean up the garbage or stains accumulated in the mounting cavity 101 corresponding to the end of the cleaning component 20. This avoids the problem that garbage and stains affect the rotation speed of the cleaning component 20 after long-term operation of the cleaning equipment, ultimately leading to a decrease in the cleaning ability of the cleaning equipment. In this application, the distance L1 between the first end 31 of the strip-shaped protrusion 30 and the outer edge of the first end face 211 is greater than the distance L2 between the second end 32 and the outer edge of the first end face 211, to avoid the accumulation of more garbage and stains on the first end 31. At the same time, the strip-shaped protrusion 30 has a certain eccentric force, so that garbage and stains are not easily accumulated on the strip-shaped protrusion 30. On the other hand, the strip-shaped protrusion 30 of this application includes a peripheral side surface and a top surface, at least one of which is a smooth arc surface, further preventing garbage and stains from depositing on the strip-shaped protrusion 30. Finally, the strip-shaped protrusion 30 of this application has a concave arc surface on at least one side along the width direction. The concave arc surface has a certain guiding effect, which can guide garbage or stains to the first end 31 or the second end 32. The setting of the concave arc surface makes the strip-shaped protrusion 30 have redundant space, so as to avoid the solid garbage being compressed when the strip-shaped protrusion 30 agitates the solid garbage.
[0082] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0083] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.
[0084] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
