[0025] Further, the cleaning strip component has a first segment and a second segment, the first segment extending from a first end of the roller component to a second end of the roller component opposite to the first end and in a direction inclined to the axis of the roller component, the second segment extending from the second end of the roller component to the first end of the roller component and in a direction inclined to the axis of the roller component, the second segment connecting to the first segment to form a first V-shaped structure of the cleaning strip component; and / or,

[0031] On the other hand, this application also provides a cleaning device, which includes the cleaning components described above.

[0032] Compared to existing technologies, the cleaning assembly of this application features a flexible support sleeve around the outer periphery of the roller component. A cleaning strip component and a cleaning tufting component are disposed on the outer surface of the flexible support sleeve, with the cleaning tufting component exhibiting greater flexibility than both the cleaning strip component and the flexible support sleeve. When the cleaning assembly cleans a flexible surface, the cleaning strip component, being less flexible than the cleaning tufting component, can penetrate deeply into the flexible surface for thorough cleaning. However, when cleaning a hard surface, the greater flexibility of the cleaning tufting component allows it to adhere better to the hard surface upon contact, increasing the contact area between the hard surface and the cleaning assembly and thus improving the cleaning effect. On the other hand, thanks to the design of the flexible support sleeve, when the flexible support sleeve comes into contact with a hard or flexible surface, the flexible support sleeve will undergo a certain deformation, which allows the cleaning strip component and the cleaning bristle component set on the flexible support sleeve to better contact the flexible or hard surface, thereby increasing the contact area between the cleaning component and the surface to be cleaned and improving the cleaning effect of the cleaning component.

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.

[0048] In related technologies, cleaning equipment includes at least a cleaning component 1 and a dust box 3. The bottom of the cleaning equipment has an installation cavity 2. The cleaning component 1 is rotatably installed in the installation cavity 2. The dust box 3 is placed in the cleaning equipment and adsorbs the installation cavity 2 so that the garbage or stains cleaned by the cleaning component 1 are adsorbed into the dust box 3.

[0049] In related technologies, a cleaning assembly 1 typically includes a roller component 10 and a cleaning strip component 30, with the cleaning strip component 30 disposed on the roller component 10. In these technologies, when the cleaning assembly 1 cleans a surface to be cleaned, if the surface is a flexible surface, such as a blanket, the cleaning strip component 30 has low flexibility (the "flexibility" of the cleaning strip component 30 refers to the degree of deformation of the cleaning strip component 30 after being subjected to external force; the greater the deformation, the greater the flexibility of the cleaning strip component 30, and vice versa). This allows the cleaning strip component 30 to penetrate deep into the flexible surface, thus cleaning it effectively. However, when the surface to be cleaned is a hard surface, due to the low flexibility of the cleaning strip component 30, the contact between the cleaning strip component 30 and the hard surface is close to rigid contact. This results in a small effective contact area between the cleaning strip component 30 and the hard surface, making it difficult for the cleaning strip component 30 to remove debris or stains from the hard surface, thus causing poor cleaning performance of the cleaning assembly 1.

[0050] To address the aforementioned problems, according to one aspect of this application, see Appendix Figures 1 to 8 This application provides a cleaning component 1, which includes a roller component 10, a flexible support sleeve 20, a cleaning strip component 30, and a cleaning tufting component 40.

[0051] The flexible support sleeve 20 is fitted around the outer periphery of the roller component 10. The cleaning strip component 30 is disposed on the outer surface of the flexible support sleeve 20 and protrudes from the outer surface of the flexible support sleeve 20. The cleaning tufting component 40 is disposed on the outer surface of the flexible support sleeve 20, protrudes from the outer surface of the flexible support sleeve 20, and the flexibility of the cleaning tufting component 40 is greater than that of the cleaning strip component 30 and the flexible support sleeve 20.

[0052] Compared to existing technologies, the cleaning assembly 1 of this application has a flexible support sleeve 20 fitted around the outer periphery of the roller component 10, and a cleaning strip component 30 and a cleaning bristle-planting component 40 are provided on the outer surface of the flexible support sleeve 20. The cleaning bristle-planting component 40 is more flexible than the cleaning strip component 30 and the flexible support sleeve 20. When the cleaning assembly 1 cleans a flexible surface, the cleaning strip component 30 is less flexible than the cleaning bristle-planting component 40, allowing the cleaning strip component 30 to penetrate deep into the flexible surface for cleaning. However, when the cleaning assembly 1 cleans a hard surface, because the cleaning bristle-planting component 40 is more flexible than the cleaning strip component 30, it adheres better to the hard surface after contact, thereby increasing the contact area between the hard surface and the cleaning assembly 1 and improving the cleaning effect of the cleaning assembly 1. On the other hand, thanks to the design of the flexible support sleeve 20, when the flexible support sleeve 20 comes into contact with a hard or flexible surface, the flexible support sleeve 20 will undergo a certain deformation, thereby enabling the cleaning strip component 30 and the cleaning bristle component 40 set on the flexible support sleeve 20 to better contact the flexible or hard surface, thereby increasing the contact area between the cleaning component 1 and the surface to be cleaned and improving the cleaning effect of the cleaning component 1.

[0053] It is understood that, due to the high flexibility of the cleaning and tufting component 40, it may detach from the flexible support sleeve 20 after contacting the surface to be cleaned, due to the force exerted by the surface. Therefore, in this embodiment, a limiting mounting portion 21 is provided on the outer surface of the flexible support sleeve 20, and the cleaning and tufting component 40 is mounted on the limiting mounting portion 21, which is used to limit the cleaning and tufting component 40.

[0054] Furthermore, the limiting installation part 21 includes a limiting groove 212, and the cleaning and tufting component 40 is installed in the limiting groove 212, with the cleaning and tufting component 40 protruding from the opening of the limiting groove 212. Thanks to the design of the limiting groove 212, when the cleaning and tufting component 40 contacts the surface to be cleaned, only the portion of the cleaning and tufting component 40 protruding from the opening of the limiting groove 212 contacts the surface to be cleaned, while the cleaning and tufting component 40 located within the limiting groove 212 does not directly contact the surface to be cleaned. Therefore, the cleaning and tufting component 40 is not easily subjected to the force of the surface to be cleaned, preventing the cleaning and tufting component 40 from detaching from the limiting groove 212.

[0055] In some embodiments, the limiting mounting portion 21 further includes two limiting protrusions 211, which are spaced apart circumferentially along the flexible support sleeve 20 and extend from the first end to the second end of the flexible support sleeve 20. The gap between the two limiting protrusions 211 forms a limiting groove 212.

[0056] Specifically, when the cleaning component 1 comes into contact with the surface to be cleaned, because the limiting protrusion 211 protrudes from the outer surface of the flexible support sleeve 20, the cleaning tufting component 40 located in the limiting groove 212 between the two limiting protrusions 211 will not directly contact the surface to be cleaned after the surface to be cleaned comes into contact with the limiting protrusion 211. In other words, by providing the limiting groove 212 between the two limiting protrusions 211, the portion of the cleaning tufting component 40 located in the limiting groove 212 can be protected, preventing the surface to be cleaned from directly contacting the component and causing the cleaning tufting component 40 to detach from the flexible support sleeve 20.

[0057] In some embodiments, the height of the cleaning tufting component 40 protruding from the flexible support sleeve 20 is greater than the height of the cleaning strip component 30 protruding from the flexible support sleeve 20. The height of the cleaning strip component 30 protruding from the flexible support sleeve 20 is greater than the height of the limiting protrusion 211 protruding from the flexible support sleeve 20.

[0058] It is known that, because the flexibility of the cleaning tufting component 40 is greater than that of the cleaning strip component 30, when the cleaning assembly 1 cleans the surface to be cleaned, the cleaning tufting component 40 deforms more significantly. After deformation, it is easier for it to contact the surface to be cleaned, thus increasing the contact area between the cleaning assembly 1 and the surface to be cleaned, thereby improving the cleaning effect. In this embodiment, the height of the cleaning tufting component 40 protruding from the flexible support sleeve 20 is greater than the height of the cleaning strip component 30 protruding from the flexible support sleeve 20. This allows more of the cleaning tufting component 40 to deform and contact the surface to be cleaned, further improving the cleaning effect of the cleaning assembly 1. On the other hand, when hair is wrapped around the cleaning assembly 1, because the height of the cleaning strip component 30 protruding from the flexible support sleeve 20 is greater than the height of the limiting protrusion 211 protruding from the flexible support sleeve 20, this can, to a certain extent, prevent the hair from getting stuck at the root of the cleaning tufting component 40, allowing the adsorption force applied by the dust box 3 to the hair to be adsorbed into the dust box 3. In other words, when hair gets stuck at the base of the cleaning and hair-planting component 40, the contact area between the hair and the component increases. Each contact area exerts an external force on the hair, resulting in greater friction and making it less likely to be sucked away by the dust box 3. Furthermore, the increased distance between the hair and the dust box 3 also reduces the suction power of the dust box 3 at the base of the cleaning and hair-planting component 40.

[0059] Furthermore, both the cleaning strip component 30 and the cleaning tufting component 40 include multiple components, and the multiple cleaning strip components 30 and the multiple cleaning tufting components 40 are arranged alternately at intervals along the circumference of the flexible support sleeve 20.

[0060] Specifically, "multiple cleaning strip components 30 and multiple cleaning tufting components 40 are alternately arranged along the circumference of the flexible support sleeve 20" means that the cleaning strip components 30 and cleaning tufting components 40 are alternately arranged in sequence along the circumferential direction of the flexible support sleeve 20. That is, along the circumferential direction of the flexible support sleeve 20, there is a cleaning tufting component 40 between two cleaning strip components 30, or a cleaning strip component 30 between two cleaning tufting components 40. In addition, since the cleaning assembly 1 is rotatably disposed in the mounting cavity 2, the alternating arrangement of multiple cleaning strip components 30 and multiple cleaning tufting components 40 along the circumferential direction of the flexible support sleeve 20 can increase the contact area between the cleaning assembly 1 and the surface to be cleaned per unit time, thereby improving the cleaning efficiency of the cleaning assembly 1.

[0061] In some embodiments, the cleaning strip component 30 and the flexible support sleeve 20 are integrally formed to improve the connection stability between the cleaning strip component 30 and the flexible support sleeve 20, and to reduce the assembly steps of the cleaning strip component 30 and the flexible support sleeve 20. Of course, the cleaning strip component 30 can also be connected by adhesive or welding. Any other modifications within the scope of this application are within the protection scope of this application.

[0062] In some embodiments, the cleaning and tufting component 40 is bonded to the limiting mounting portion 21, that is, the cleaning and tufting component 40 is bonded to the limiting groove 212, so that an adhesive layer is formed between the cleaning and tufting component 40 located in the limiting groove 212 and the limiting groove 212, which improves the connection stability of this part and prevents external force from being transmitted to this part, causing this part to separate from the limiting groove 212.

[0063] In actual operation of the cleaning equipment, when there is large debris on the surface to be cleaned, the cleaning component 1 may be jammed by the large debris, causing the cleaning component 1 to malfunction. To solve the problem of the cleaning component 1 being jammed by large debris, in this embodiment, the roller component 10 includes a rotating shaft 11 and a flexible support part 12. The flexible support part 12 is fixedly sleeved on the outer periphery of the rotating shaft 11, and the flexible support sleeve 20 is fixedly sleeved on the outer periphery of the flexible support part 12.

[0064] Specifically, the flexible support portion 12 increases the deformability of the cleaning component 1. That is, when the cleaning component 1 encounters large debris, the flexible support portion 12 allows the cleaning component 1 at the contact point with the large debris to deform along the direction close to the rotating shaft 11, ultimately allowing the cleaning component 1 to pass over the large debris and preventing it from jamming. It is worth mentioning that although the flexible support sleeve 20 can also deform to a certain extent when in contact with debris, thus avoiding it, when the debris is large, the deformation of the flexible support sleeve 20 cannot guarantee that the cleaning component 1 can pass over the large debris. Therefore, the flexible support portion 12 is necessary. In some embodiments, a guide plate 4 is provided on the cleaning device. The guide plate 4 is disposed within the mounting cavity 2 and extends from the opening of the mounting cavity 2 to the connection port between the dust box 3 and the mounting cavity 2. There is a gap between the guide plate 4 and the flexible support sleeve 20. When the dust box 3 applies suction to the mounting cavity 2, external gas can enter the dust box 3 through the gap between the guide plate 4 and the flexible support sleeve 20. In this embodiment, since the flexible bearing portion 12 is disposed between the rotating shaft 11 and the flexible support sleeve 20, and the flexible bearing portion 12 plays a filling role, the overall outer diameter of the flexible support sleeve 20 will increase to a certain extent. This, in turn, reduces the gap between the flexible support sleeve 20 and the guide plate 4. When the suction force provided by the dust box 3 remains constant, the reduced gap between the flexible support sleeve 20 and the guide plate 4 increases the velocity of the gas entering the gap, thereby facilitating the gas to carry the debris attached to the flexible support sleeve 20, the cleaning tufting component 40, and the cleaning strip component 30 into the dust box 3.

[0065] Optionally, the flexible support part 12 can be a silicone gel sleeve, a sponge sleeve, or a rubber sleeve. Specifically, the silicone gel sleeve, sponge sleeve, and rubber sleeve all have a certain degree of elasticity and deformation capability. When the cleaning component 1 comes into contact with large-sized debris, the silicone gel sleeve, sponge sleeve, or rubber sleeve has a certain degree of deformation capability, allowing the cleaning component 1 to easily pass over the large-sized debris and sweep it into the dust box 3. This prevents large-sized debris from getting stuck between the bottom of the cleaning component 1 and the surface to be cleaned during the cleaning process, thus avoiding scratching the cleaning component 1 or the surface to be cleaned. In addition, because the silicone gel sleeve, sponge sleeve, and rubber sleeve have a certain degree of elasticity, after the cleaning component 1 sweeps the large-sized debris into the dust box 3, the cleaning component 1 will return to its state before contacting the large-sized debris and clean the surface to be cleaned.

[0066] Furthermore, the flexible support sleeve 20 includes a rubber sleeve 201, the cleaning strip component 30 includes a rubber strip 301, and the cleaning tufting component 40 includes a tuft 401. Specifically, the rubber sleeve 201, rubber strip 301, and tuft 401 provide the flexible support sleeve 20, cleaning strip component 30, and cleaning tufting component 40 with good flexibility, allowing them to deform to a certain extent after contacting the surface to be cleaned, thereby increasing the contact area between the cleaning component 1 and the surface to be cleaned.

[0067] Furthermore, the maximum distance L1 from the top of the cleaning and tufting component 40 protruding from the flexible support sleeve 20 to the axis of the roller component 10 and the maximum distance L2 from the end of the flexible support sleeve 20 away from the axis of the roller component 10 to the axis of the roller component 10 satisfy the following relationship: 0.67≤L2 / L1≤0.87.

[0068] It can be seen that, since the cleaning component 1 is set inside the mounting cavity 2 of the cleaning equipment, when the size of L2 relative to L1 is moderate, i.e., 0.67≤L2 / L1≤0.87, the gap between the flexible support sleeve 20 and the guide plate 4 is relatively small. When the power of the fan used to draw negative pressure from the dust box 3 on the cleaning equipment is constant, the smaller gap makes the wind speed passing through the gap relatively fast, thus facilitating the dust box 3 to absorb the garbage or stains on the cleaning component 1 into the dust box 3, avoiding the accumulation of garbage on the cleaning component 1 and the resulting decrease in the cleaning effect of the cleaning component 1. At this time, the length of the protrusion of the cleaning tufted component 40 from the flexible support sleeve 20 is moderate, and the cleaning component 1 has a good cleaning effect. However, if the size of L2 is too small relative to L1, for example, L2 / L1 is less than 0.67, since the restrictive effect of the cleaning tufted component 40 on the airflow is small, the gap between the cleaning component 1 and the guide plate 4 is relatively large, resulting in a relatively low airflow velocity passing through the gap, making it difficult for the dust box 3 to suck up the garbage on the cleaning component 1. If the size of L2 is too large relative to L1, i.e., L2 / L1 is greater than 0.87, this will result in the size of the cleaning tufting component 40 being relatively small, thus affecting the cleaning efficiency of the cleaning component 1. The value of L2 / L1 can be 0.67, 0.7, 0.72, 0.74, 0.76, 0.78, 0.80, 0.82, 0.84, and 0.87.

[0069] In some embodiments, the maximum distance L1 from the top of the cleaning tufting component 40 protruding from the top of the flexible support sleeve 20 to the axis of the roller component 10 satisfies the relationship: 19mm≤L1≤21mm.

[0070] In some embodiments, the maximum distance L2 from the end of the flexible support sleeve 20 away from the axis of the roller component 10 to the axis of the roller component 10 satisfies the relationship: 14mm ≤ L2 ≤ 16mm. It is understood that the larger the maximum distance L2 from the end of the flexible support sleeve 20 away from the axis of the roller component 10 to the axis of the roller component 10, for example, L2 greater than 14mm, the smaller the gap between the flexible support sleeve 20 and the side wall of the mounting cavity 2, and the greater the airflow velocity through this gap. However, when L2 is too large, for example, L2 greater than 16mm, on the one hand, it requires a larger size for the flexible support sleeve 20 and the flexible support portion 12, increasing the manufacturing cost of the cleaning assembly 1; on the other hand, if the flexible support sleeve 20 is too large, the space reserved for the cleaning tufting component 40 is smaller, resulting in the cleaning tufting component 40 protruding too short from the flexible support sleeve 20, reducing the cleaning effect of the cleaning assembly 1. That is, the cleaning tufting component 40 is too short, resulting in less effective contact surface when the cleaning tufting component 40 contacts the surface to be cleaned. The value of L2 can be 14mm, 14.2mm, 14.4mm, 14.6mm, 14.8mm, 15mm, 15.2mm, 15.4mm, 15.6mm, 15.8mm and 16mm.

[0071] As attached Figure 3 As shown, the cleaning strip component 30 has a first segment 31 and a second segment 32. The first segment 31 extends from the first end of the roller component 10 to the second end of the roller component 10 opposite to the first end and in a direction inclined to the axis of the roller component 10. The second segment 32 extends from the second end of the roller component 10 to the first end of the roller component 10 and in a direction inclined to the axis of the roller component 10. The second segment 32 is connected to the first segment 31 so that the cleaning strip component 30 forms a first V-shaped structure.

[0072] Specifically, when the cleaning component 1 cleans the floor, the cleaning strip component 30 forms a first V-shaped structure, allowing the debris cleaned by the cleaning strip component 30 to move along both sides of the first V-shaped structure to the center, thus facilitating the dust box 3 to suck in the debris cleaned by the cleaning strip component 30. In one specific embodiment, the connection port between the dust box 3 and the mounting cavity 2 is directly opposite the center of the roller component 10 along its length. The first segment 31 is along a first inclined direction (for example, the first inclined direction could be...). Figure 3 The second segment 32 extends obliquely from the first end of the roller component 10 in the X1 direction and extends to the middle region of the length direction of the roller component 10. The second segment 32 extends along the second oblique direction (for example, the second oblique direction could be...). Figure 3The first V-shaped structure is formed by the first segment 31 and the second segment 32 of the different cleaning strip components 30 having different first and second tilting directions.

[0073] Furthermore, the cleaning and tufting component 40 has a third segment 41 and a fourth segment 42. The third segment 41 extends from the first end of the roller component 10 to the second end of the roller component 10 opposite to the first end and in a direction inclined to the axis of the roller component 10. The fourth segment 42 extends from the second end of the roller component 10 to the first end of the roller component 10 and in a direction inclined to the axis of the roller component 10. The fourth segment 42 is connected to the third segment 41 so that the cleaning and tufting component 40 forms a second V-shaped structure.

[0074] Similar to the cleaning strip component 30, when the cleaning tufting component 40 cleans the surface to be cleaned, the debris or stains cleaned by the cleaning tufting component 40 can move along both sides of the second V-shaped structure to the middle of the second V-shaped structure, thereby facilitating the dust box 3 to suck up the debris or stains. In a specific embodiment, the third segment 41 extends from the first end of the roller component 10 along a first inclined direction to the middle region of the length direction of the roller component 10, and the fourth segment 42 extends from the second end of the roller component 10 along a second inclined direction to the middle region of the length direction of the roller component 10.

[0075] Furthermore, the adhesive strip 301 protrudes from the outer surface of the flexible support sleeve 20, and the height H1 of the adhesive strip 301 protruding from the flexible support sleeve 20 and the height H2 of the bristle 401 protruding from the flexible support sleeve 20 satisfy the relationship 0.25≤H1 / H2≤0.4. When H1 / H2 satisfies the above relationship, H1 will not be too high relative to H2. After the cleaning component 1 contacts the surface to be cleaned, the bristle 401 can contact the surface to be cleaned, and under the action of the surface to be cleaned, a part of the bristle 401 can adhere to the surface to be cleaned, thereby increasing the effective cleaning surface area between the bristle 401 and the surface to be cleaned. At the same time, H1 will not be too low relative to H2. The adhesive strip 301 can support the bristle 401, that is, under the action of the adhesive strip 301, hair is not easy to get tangled at the root of the bristle 401, and the adsorption force of the dust box 3 on the hair at the root of the bristle 401 can make the hair enter the dust box 3. In this embodiment, the values ​​of H1 / H2 can be 0.25, 0.30, 0.35, and 0.40.

[0076] In some embodiments, the height H1 of the adhesive strip 301 protruding from the flexible support sleeve 20 satisfies the relationship: 3mm ≤ H1 ≤ 4mm. Specifically, if H1 is greater than 4mm, this will result in the adhesive strip 301 protruding too far from the flexible support sleeve 20, leading to a poor cleaning effect of the bristle strip 401 on the surface to be cleaned. If H1 is less than 3mm, this may cause the adhesive strip 301 to fail to restrict hair during cleaning, resulting in hair embedding into the root of the bristle strip 401, making it difficult for the suction of the dust box 3 to remove the hair, ultimately reducing the cleaning effect of the cleaning component 1. The value of H1 can be 3mm, 3.2mm, 3.4mm, 3.6mm, 3.8mm, and 4mm.

[0077] Furthermore, the bristle 401 protrudes from the outer surface of the flexible support sleeve 20. The height H2 of the bristle 401 protruding from the flexible support sleeve 20 satisfies the relationship: 10mm ≤ H2 ≤ 12mm. When H2 satisfies the above relationship, the height of the bristle 401 protruding from the flexible support sleeve 20 will not be too high. If the height of the bristle 401 is too high, it may cause the bristle 401 to deform upon contact with the surface to be cleaned and become entangled with other bristle 401s, ultimately affecting the cleaning efficiency of the cleaning component 1. At the same time, if the bristle 401 protrudes too high from the flexible support sleeve 20, the friction between the bristle 401 and the inner wall of the mounting cavity 2 will be too large when the cleaning component 1 rotates within the mounting cavity 2, thus affecting the rotation speed of the cleaning component 1. In addition, when H2 satisfies the above relationship, the height of the bristle 401 protruding from the flexible support sleeve 20 will not be too low. At this time, after the bristle 401 contacts the surface to be cleaned, the deformed bristle 401 has a large contact area with the surface to be cleaned. The value of H2 can be 10mm, 10.5mm, 11mm, 11.5mm and 12mm.

[0078] In some embodiments, the bristle strip 401 includes a plurality of fine bristles 4011, which are spaced apart along the length of the bristle strip 401. The diameter R1 of the fine bristles 4011 satisfies the relationship: 0.04mm ≤ R1 ≤ 0.06mm. It is understood that the smaller the diameter of the fine bristles 4011, the lower their rigidity, and therefore the higher their flexibility. After contacting the surface to be cleaned, the fine bristles 4011 deform more and have a larger contact area. When R1 satisfies the above relationship, the diameter of the fine bristles 4011 will not be too low, causing them to easily break under external force, nor will it be too large, thus affecting their flexibility. In this embodiment, the value of R1 can be 0.04mm, 0.045mm, 0.05mm, 0.055mm, or 0.06mm.

[0079] In some embodiments, the cleaning hair implantation component 40 includes a hair implantation part 402 and a connecting part 403 adapted to the limiting groove 212. The hair implantation part 402 is fixedly connected to the connecting part 403, and the connecting part 403 is bonded to the limiting groove 212.

[0080] Specifically, the connecting part 403 is a connecting block, and the bristle-planting part includes multiple fine bristles 4011, each fine bristle 4011 being fixedly connected to the connecting part 403. The connecting part 403 is bonded to the limiting groove 212, thereby improving the connection stability of the cleaning bristle-planting component 40. That is, when the cleaning component 1 is subjected to excessive force, and the connecting part 403 comes into contact with the surface to be cleaned, the presence of the connecting block prevents the roots of the bristle-planting part 402 from directly contacting the surface to be cleaned, thus preventing the bristle-planting part 402 from detaching from the connecting part 403. It is worth mentioning that the reason for adapting the connecting part 403 to the limiting groove 212 is to increase the connection area between the connecting part 403 and the limiting groove 212, thereby improving the connection stability of the connecting part 403. In some specific embodiments, the limiting groove 212 includes a rectangular groove, and the connecting part 403 includes a rectangular block adapted to the rectangular groove. Optionally, the hair-planting part 402 and the connecting part 403 are integrally formed, or one end of the hair-planting part 402 is inserted and fixed inside the connecting part 403.

[0081] In some embodiments, felt 111 is fitted at both ends of the rotating shaft 11 near the end, and the felt 111 can be used to prevent hair or other debris from accumulating at the end of the rotating shaft 11.

[0082] Furthermore, according to the formula Q = V * A, where Q is the gas flow rate, V is the gas velocity, and A is the cross-sectional area of ​​the gas passage, it can be seen that when the gas flow rate is constant, the smaller the cross-sectional area, the faster the gas velocity. The faster the gas velocity through cleaning component 1, the easier it is for debris to be sucked into dust box 3, resulting in a better cleaning effect from cleaning component 1. Therefore, this application provides the following specific embodiments to illustrate that the cleaning effect of this application is superior to related technologies:

[0083] Example 1:

[0084] With L1 set to 20mm and L2 set to 14mm, the cross-sectional area of ​​the channel formed by the felt 401 for airflow is 0.0006408864m². 2 Ignoring other factors, the gas velocity at this time is V1 = Q / 0.0006408864.

[0085] Example 2:

[0086] Unlike Example 1, L2 is set to 15 mm, in which case the cross-sectional area of ​​the channel formed by the felt 401 through which airflow can pass is 0.00054978 m². 2At this point, the gas velocity is V1, which is Q / 0.00054978.

[0087] Example 3:

[0088] Unlike Example 1, L2 is set to 16 mm, in which case the cross-sectional area of ​​the channel formed by the felt 401 through which airflow can pass is 0.0004524 m². 2 At this point, the gas velocity is V1, which is Q / 0.0004524.

[0089] Comparative Example 1:

[0090] Comparative Example 1 uses data provided in related technologies. In the cleaning assembly 1 of the comparative example, the adhesive strip 301 protrudes from the rotating shaft 11, and the distance from the end of the adhesive strip 301 protruding from the rotating shaft 11 to the axis of the rotating shaft 11 is 20 mm. The radius of the rotating shaft 11 is 6 mm. At this time, the cross-sectional area of ​​the channel through which the airflow can pass formed by the bristle 401 is 0.0011435 m². 2 At this point, the gas velocity is V1, which is Q / 0.0011435.

[0091] As attached Figure 9 As shown, by comparing Examples 1, 2, and 3 with Comparative Example 1, it can be found that when the suction power of the dust box 3 remains unchanged, that is, when Q remains unchanged, the air force passing through the cleaning component 1 in Example 1 is 1.784 times that in Comparative Example 1, the air force passing through the cleaning component 1 in Example 2 is 2.08 times that in Comparative Example 1, and the air force passing through the cleaning component 1 in Example 3 is 2.528 times that in Comparative Example 1.

[0092] In summary, this application, through the arrangement of the flexible support sleeve 20, the cleaning strip component 30, and the cleaning bristle implantation component 40, increases the effective contact area between the cleaning component 1 and the surface to be cleaned during cleaning, thereby improving the cleaning effect of the cleaning component 1. Furthermore, a limiting groove 212 is provided on the flexible support sleeve 20 to prevent the surface to be cleaned from contacting the portion of the cleaning bristle implantation component 40 located within the limiting groove 212, thus preventing the cleaning bristle implantation component 40 from detaching from the flexible support sleeve 20 due to the action of the surface to be cleaned. In addition, this application provides a flexible bearing portion 12 between the rotating shaft 11 and the flexible support sleeve 20, giving the cleaning component 1 a higher degree of deformation. When the cleaning component 1 comes into contact with larger pieces of debris, it can avoid or pass over the larger debris through deformation, thereby preventing the larger debris from jamming the cleaning component 1. On the other hand, by limiting the size and proportion of L1, L2, H1, and H2, this application increases the wind speed acting on the cleaning component 1, thereby facilitating the suction of debris from the cleaning component 1 into the dust box 3 of the cleaning equipment, preventing debris from accumulating on the cleaning component 1 and affecting its cleaning effect. In this application, the cleaning strip component 30 forms a first V-shaped structure on the outer periphery of the flexible support sleeve 20, and the cleaning tufting component 40 forms a second V-shaped structure on the outer periphery of the flexible support sleeve 20. The first and second V-shaped structures have a guiding effect on debris and stains, facilitating the cleaning component 1 to guide debris or stains to a designated area so that the dust box 3 can suck them away.

[0093] 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.

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.
