[0002] This application claims priority to Chinese invention patent application No. 202510703216.2, filed on May 28, 2025, entitled "Cleaning Head and Cleaning Equipment"; Chinese utility model patent application No. 202521077219.1, entitled "Cleaning Head and Cleaning Equipment"; and Chinese utility model patent application No. 202521077208.3, entitled "Cleaning Head and Cleaning Equipment," the entire contents of which are incorporated herein by reference. Technical Field

[0003] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning component, a cleaning head, and a cleaning device. Background Technology

[0004] As people's living standards continue to improve, more and more families are adopting cleaning equipment (such as robotic vacuum cleaners or robot vacuum and mop combos) for daily cleaning. These devices typically have cleaning components at the suction port to enhance the cleaning effect on the floor. However, in actual use, because the cleaning components are in direct contact with the floor, they are prone to getting tangled with filamentous objects such as debris. When a large amount of debris gets tangled on the cleaning components, it not only reduces the suction efficiency of the cleaning device but may also obstruct the rotation of the cleaning components, leading to motor stalling, affecting the normal operation of the device and shortening its lifespan. Currently, users mainly rely on manually removing the debris from the cleaning components, which is not only time-consuming and laborious but also brings many inconveniences to users.

[0024] The first transmission mechanism includes a slider that is movably disposed relative to the base along the axial direction and / or radial direction of the base, and another cutting portion is fixedly mounted to the slider and at least partially protrudes outward from the surface of the base.

[0025] Optionally, one of the slider and the base is provided with a guide groove, and the other is provided with a guide portion that cooperates with the guide groove. The base rotates so that the guide portion and the guide groove drive the slider to move relative to the base.

[0037] By placing the cutting structure between two adjacent cleaning sections and setting the central angle A within the range of 70° to 160°, when tangled material (such as hair) wraps around the cleaning component, it is tensioned and stretched taut by the two adjacent cleaning sections. The tangled material adheres to the surface of the cutting structure located between the two cleaning sections. The cutting structure is fully exposed in the movement path of the tangled material and forms a good contact with it, thereby improving cutting efficiency and reliability. At the same time, without affecting the coverage of the cleaning section on the roller brush surface, this angle range can also maximize the effective area of ​​the cutting structure, ensuring that it can efficiently remove tangled material without affecting the cleaning component's ability to guide and collect dirt on the roller brush.

[0057] This utility model provides a cleaning component 100, which is disposed within a cleaning head. This cleaning head is suitable for cleaning floors, tabletops, and beds, etc. The cleaning head can be applied to household cleaning equipment such as vacuum cleaners, sweepers, floor scrubbers, mite removers, fabric cleaners, carpet cleaners, pet debris removers, and handheld multi-functional cleaners. For ease of explanation, the specific structure of the cleaning head will be described below using its application in cleaning equipment as an example; other equipment can be adapted accordingly.

[0058] Please see Figures 1 to 3 In some embodiments of this utility model, the cleaning component 100 includes a base 10, at least two cleaning portions 20, and a cutting structure 30. The base 10 is rotatably configured about its axis. The cleaning portions 20 protrude radially outward from the outer peripheral surface of the base 10, and at least two cleaning portions 20 extend axially along the base 10 and are spaced apart circumferentially along the base 10. The cutting structure 30 is mounted on the base 10 and extends radially outward from the outer peripheral surface of the base 10. The cutting structure 30 is disposed between two adjacent cleaning portions 20 and is used to cut the entanglement wrapped around the two cleaning portions 20 and extending between the two cleaning portions 20. In the cross-section of the cleaning component 100, the central angle between the cutting structure 30 and the cleaning portion 20 located on the side corresponding to the base 10 is set to A, where 70°≤A≤160°.

[0059] Understandably, the base 10 has a columnar structure and is rotatably disposed inside the cleaning device around its own axis. The outer peripheral surface of the base 10 is cylindrical, and a plurality of cleaning parts 20 are evenly distributed around its axis. Each cleaning part 20 protrudes radially outward from the outer peripheral surface of the base 10 and extends a certain length axially from the base 10. The cleaning parts 20 are not integrally laid on the outer peripheral surface of the base 10, but are spaced apart in the circumferential direction of the base 10.

[0060] It should be noted that the cleaning unit 20 can be made of materials such as brush bristles or soft rubber strips, depending on the object being cleaned and the environment in which it is used. Brush bristles have a certain degree of rigidity and can effectively scrape away dust particles on the floor; while soft rubber strips are suitable for smoother floor surfaces.

[0061] The cutting structure 30 is preferably blade-shaped or serrated to enhance its ability to cut entangled materials. When the cleaning part 100 rotates, if the entangled material is wrapped between the two cleaning parts 20 and extends across the space between them, the entangled material will come into contact with the cutting structure 30 and be cut off by it, thereby avoiding the problem of the entangled material continuing to wrap around, which would lead to a decrease in cleaning efficiency or jamming of the parts.

[0062] On the cross-section of the cleaning part 100, that is, on the plane perpendicular to the axis of the base 10, the central angle between the cutting structure 30 and any cleaning part 20 located beside it and the base 10 is defined as A, and the range of this angle is limited to 70°≤A≤160°.

[0063] It should be noted that when the central angle A is less than 70°, the circumferential distance between the two cleaning sections 20 is too small. This results in the cutting structure 30's radial dimension at the base 10 not being sufficiently exposed in areas where the entangled material may become entangled. This is especially true when the cleaning section 20 uses a soft rubber strip. Due to the strip's elasticity, the entangled material tends to wrap around its end furthest from the base 10 (i.e., the free end), which is far from the cutting structure 30 and difficult to cut effectively. In this case, even with the cutting structure 30 present, the intended cutting function is difficult to achieve, reducing the overall anti-entanglement capability of the cleaning component 100.

[0064] When the central angle A is greater than 160°, although the exposed area of ​​the cutting structure 30 is large, the gap between the two cleaning sections 20 is too large. This will cause some hair to fail to be guided to the vicinity of the cutting structure 30 in time during the cleaning process, thereby reducing the cutting efficiency. It may also affect the coverage density of the cleaning section 20 on the roller brush surface, weakening its ability to collect the tangled material on the roller brush surface.

[0065] Therefore, setting the central angle A between 70° and 160° can ensure good coverage of the cleaning section 20 on the roller brush surface, while allowing the hair to press against the cutting structure 30 as much as possible during the winding process, thereby improving cutting efficiency and reducing the frequency of manual cleaning.

[0066] By positioning the cutting structure 30 between two adjacent cleaning sections 20 and setting the central angle A within a range of 70° to 160°, when tangled material (such as hair) wraps around the cleaning component 100, it is stretched and taut by the two adjacent cleaning sections 20. The tangled material adheres to the surface of the cutting structure 30 located between the two cleaning sections 20. The cutting structure 30 is fully exposed in the movement path of the tangled material and forms a good contact with it, thereby improving cutting efficiency and reliability. At the same time, without affecting the coverage of the cleaning section 20 on the roller brush surface, this angle range can also maximize the effective area of ​​the cutting structure 30, ensuring that it can efficiently remove tangled material without affecting the cleaning component 100's ability to guide and collect dirt on the roller brush.

[0067] Preferably, the central angle A of the base 10 between the cutting structure 30 and the two adjacent cleaning sections 20 in the cleaning component 100 satisfies 80°≤A≤140°. Within this angle range, the cutting structure 30 can be fully exposed in the path that hair may pass through, and a high cutting success rate can be achieved regardless of whether the cleaning section 20 uses rigid bristles or flexible rubber strips. Especially for the soft rubber strip, since its free end is more likely to gather hair, setting the angle value within this range allows the cutting structure 30 to better cover the area, thereby effectively avoiding the problem of hair continuing to entangle without being cut. At the same time, this angle range also ensures the distribution density of the cleaning section 20 in the circumferential direction of the base 10, so that it can still form a relatively continuous scraping action on the surface of the other cleaning component 100 (roller brush), improving the capture rate of entangled objects.

[0068] More preferably, the central angle A is further limited to 90°≤A≤130°. Within this range, the circumferential spacing between the cleaning sections 20 is more moderate, providing sufficient exposure space for the cutting structure 30 without reducing the coverage of the cleaning section 20 due to excessive spacing. At this angle, hair is more easily blocked by the cutting structure 30 during the rotation of the cleaning component 100, generating a certain tension, thereby increasing the likelihood of it being cut.

[0069] Most preferably, the central angle A is set to 100°≤A≤120°, which is the optimal range determined after extensive experimental verification. At this angle, the cutting structure 30 is located in the geometric center region between the two cleaning parts 20, and the angle between it and the cleaning parts 20 is neither too large nor too small, ensuring that the hair is naturally guided onto the cutting structure 30 during the rotation of the cleaning component 100 and is efficiently cut under appropriate tension.

[0070] Specifically, when the cleaning section 20 is a soft rubber strip, its oscillation path during rotation coincides perfectly with the working area of ​​the cutting structure 30, thereby improving the ability to handle hair entangled in the end area of ​​the soft rubber strip. Furthermore, the cleaning section 20 is more evenly distributed within this angle range, increasing the coverage density on the roller brush surface and reducing localized pressure concentration caused by uneven arrangement.

[0071] Understandably, the relative height between the cutting structure 30 and the cleaning section 20 can be reasonably set as needed to facilitate the cutting of tangled objects by the cutting structure 30. For example, the height of the cutting structure 30 may be slightly higher than the outer end of the cleaning section 20 to ensure that even if hair is tangled near the free end of the cleaning section 20, it can still contact the cutting structure 30 and be cut off.

[0072] It should be noted that, since the cleaning part 100 is designed for cleaning the part to be cleaned 100, if the height of the cutting structure 30 is slightly higher than the outer end of the cleaning part 20, it will extend excessively and come into direct contact with the part to be cleaned 100, which may cause the cleaning part 20 (such as bristles or soft rubber strips) of the part to be cleaned 100 to be accidentally cut, resulting in damage to the roller brush or a reduction in its service life.

[0073] To resolve the above issues, please refer to Figure 3 In this embodiment, the cutting structure 30 is located on the inner side of the outer circumference of the cleaning component 100 and does not protrude outward from the outer contour.

[0074] Specifically, the cutting structure 30 is disposed in the outer peripheral area of ​​the cleaning component 100, but does not exceed the overall outer circumferential contour of the cleaning component 100. That is, the cutting structure 30 is located on the inner side of the outer circumference of the cleaning component 100 and does not protrude outward from the outer contour formed by the cleaning part 20.

[0075] It should be noted that although the cutting structure 30 does not protrude beyond the outer contour of the cleaning component 100, it can still effectively cover the gap area between the cleaning parts 20, so that the hair is naturally guided to the vicinity of the cutting structure 30 during the rotation of the cleaning component 100, and the cutting action is completed under its tension.

[0076] Furthermore, considering that the cleaning component 100 and the cleaned component 100 usually rotate in opposite directions in the contact area during the cleaning process to enhance the peeling effect, if the height of the cutting structure 30 is too large, it will not only affect the integrity of the roller brush cleaning section 20, but also cause the friction between the cleaning component 100 and the cleaned component 100 to increase, resulting in additional noise or energy consumption.

[0077] This design avoids the possibility of the cutting structure 30 directly acting on the surface of the roller brush of the part being cleaned 100. Especially when the roller brush material is a soft rubber strip or fine bristles, it can effectively prevent accidental cutting caused by the excessive height of the cutting structure 30, thereby protecting the integrity of the cleaning part 20 of the part being cleaned 100.

[0078] Furthermore, since the dynamic balance performance of the cleaning section 20 has a significant impact on its operational stability when the cleaning component 100 rotates at high speed, please refer to [further details needed]. Figure 3 In this embodiment, the number of cleaning parts 20 is set to an even number, and they are evenly distributed in the circumferential direction of the base 10.

[0079] In this embodiment, the number of cleaning sections 20 is set to an even number, such as 2, 4, 6, or 8, preferably 2 or 4. The specific number can be matched and set according to the overall size of the cleaning component 100, the roller brush structure, and the cleaning efficiency requirements. The cleaning sections 20 are distributed at equal intervals in the circumferential direction of the base 10, that is, the included angle between any two adjacent cleaning sections 20 is equal, thereby forming a symmetrical mass distribution during the rotation of the cleaning component 100.

[0080] By setting the number of cleaning units 20 to an even number and arranging them at equal intervals, the overall dynamic balance performance of the cleaning unit 100 can be improved, reducing vibration, noise and bearing wear problems caused by uneven mass distribution.

[0081] Furthermore, an even number of the cleaning sections 20 are arranged symmetrically with respect to the cutting structure 30.

[0082] Specifically, on the cross-section of the cleaning component 100, the cleaning portions 20 corresponding to both sides of any cutting structure 30 maintain a mirror symmetry relationship in terms of structural shape, extension direction, and relative position. For example, in a configuration with 4 cleaning portions 20 and 2 cutting structures 30, 2 cleaning portions 20 are distributed on each side of each cutting structure 30, forming a symmetrical structure centered on the cutting structure 30.

[0083] Thus, the symmetrical arrangement is reflected not only in the geometric structure but also in the mass distribution and stress characteristics. When the cleaning component 100 rotates at high speed, the symmetrically arranged cleaning sections 20 can balance the centrifugal forces acting on both sides of the cutting structure 30, thereby reducing vibration, deflection, or local wear caused by the asymmetrical structure and improving the overall operational stability of the cleaning component 100.

[0084] Furthermore, since the cleaning section 20 is symmetrically arranged on both sides of the cutting structure 30, after the hair is brought into the area of ​​the cleaning component 100, it can be guided and tensioned in a similar way, regardless of which side it enters the vicinity of the cutting structure 30, thus making it easier to fit the cutting structure 30 and be cut efficiently.

[0085] In addition, the equally spaced distribution of the cutting structures 30 is coordinated with the layout of their corresponding cleaning sections 20. Each cutting structure 30 is located in the gap area between two cleaning sections 20, covering as much as possible the path that may cause entanglement.

[0086] It should be noted that, since the cutting structure 30 has a certain mass and rigidity, its distribution pattern has a certain impact on the overall dynamic balance performance when the cleaning part 100 rotates at high speed.

[0087] By setting the cutting structure 30 to an even number and arranging them at equal intervals in the circumferential direction, the mass and position of the cleaning component 100 are symmetrically distributed during rotation. The centrifugal forces generated during rotation cancel each other out, avoiding problems such as local stress concentration, increased vibration, and uneven load on the bearing 6 caused by structural asymmetry.

[0088] Based on the aforementioned embodiments, in order to adapt to different usage scenarios and the requirements of the roller brush structure for cleaning efficiency, hair guiding ability and overall dynamic balance performance, the cleaning part 20 relative to the base 10 can have a variety of implementations.

[0089] In the first embodiment, the cleaning part 20 extends along the axial direction of the base 10, and its extension direction is parallel to the axial direction of the base 10.

[0090] This structural form is the most basic and common arrangement, suitable for most standard roller brush structures. The cleaning parts 20 are evenly distributed on the outer peripheral surface of the base 10 and protrude radially outward. During rotation, they remove tangled materials (such as hair) by directly contacting the roller brush surface. Because the cleaning parts 20 are arranged in a straight line along the axial direction, this arrangement is easy to manufacture, facilitates assembly and positioning, and provides good structural stability.

[0091] The second embodiment: the cleaning part 20 is arranged in a spiral shape around the circumference of the base 10. That is, while the cleaning part 20 extends radially outward from the outer peripheral surface of the base 10, it also gradually shifts along the axial direction of the base 10, forming a spiral-like structure.

[0092] As the cleaning unit 100 rotates, the tangled material on the roller brush is guided axially towards the vicinity of the cutting structure 30, thereby increasing the likelihood that the hair will be cut by the cutting structure 30. In addition, the spiral cleaning section 20 can also play a role in assisting in the transport of foreign objects to a certain extent, enhancing the cleaning unit 100's ability to centrally process dirt.

[0093] The third embodiment: The cleaning section 20 includes two cleaning segments arranged sequentially in the axial direction of the base 10, and the two cleaning segments extend obliquely to the same side in a direction that is far apart from each other.

[0094] Specifically, each cleaning section 20 consists of two segments located at different axial positions of the base 10, and both segments extend at an inclination in the same direction (e.g., clockwise or counterclockwise). This forms a structure similar to a "V"-shaped opening tilted to the same side, which can provide a certain guiding effect during the rotation of the cleaning component 100, making it easier for hair to be drawn into the gap area between adjacent cleaning sections 20 and finally come into contact with the cutting structure 30 and be cut off.

[0095] It should be noted that the above three structural forms of the cleaning section 20 can be used individually or in combination depending on the actual application scenario. For example, a vertical cleaning section 20 can be used in a part of the cleaning component 100 to enhance structural strength, while a spiral or double-segment inclined cleaning section 20 can be used in another part to improve hair guidance and cutting efficiency.

[0096] Specifically, in this embodiment, the cleaning unit 20 includes brush bristles or rubber strips.

[0097] When the cleaning unit 20 uses bristles, the bristles are made of a fibrous material with a certain degree of rigidity, such as nylon, polyester, or composite materials, suitable for cleaning needs on hard roller brush surfaces or under high-friction conditions. The bristles have good abrasion resistance and elastic recovery ability, and can effectively scrape off dust, particles, and tangled hair adhering to the roller brush surface during the rotation of the cleaning component 100, guiding them to the vicinity of the cutting structure 30 for cutting. In addition, the bristles can be designed with different densities and lengths as needed to adapt to roller brushes of different diameters and structures.

[0098] When the cleaning unit 20 uses a rubber strip, the strip is made of flexible materials such as silicone rubber, thermoplastic elastomer (TPE), or polyurethane, suitable for roller brushes with relatively smooth or coated surfaces. The rubber strip has a certain degree of flexibility and resilience, allowing it to conform to the roller brush surface and gently peel away tangled debris during cleaning, preventing damage to the roller brush body due to excessive friction. Especially when dealing with long hair or multiple intertwined threads, the rubber strip's continuous structure makes it less susceptible to hair penetration than brush bristles, thus reducing the risk of tangling itself.

[0099] In one specific implementation, please refer to Figures 4 to 7 The cutting structure 30 includes two cutting portions 31, which extend along the axial direction of the base 10 and can move relative to each other in the axial direction (i.e., the length direction) or the radial direction. This allows the two cutting portions 31 to produce a scissor-like cutting action, thereby more effectively cutting the hair wrapped around the surface of the cleaning component 100.

[0100] To achieve the aforementioned shearing function, the cleaning head 200 also includes a first transmission mechanism 4, which is disposed between the base 10 and the two cutting sections 31. Its function is to convert the rotational motion of the base 10 into the relative motion stroke between the two cutting sections 31. For example, when the base 10 rotates, the transmission mechanism can drive one of the cutting sections 31 to slide or swing relative to the other cutting section 31, thereby generating a shearing force.

[0101] Specifically, the first transmission mechanism 4 can adopt a gear and rack structure, a cam and connecting rod structure, a screw transmission mechanism, or other similar mechanical transmission methods. These structures can convert the continuous rotational motion of the base 10 into a periodic cutting action, so that the two cutting parts 31 continuously open and close during the rotation of the cleaning part 100, and continuously perform efficient cutting treatment on the hair wrapped around its surface.

[0102] Since the cutting action between the two cutting sections 31 is driven by the rotation of the base 10 itself, no additional motor or drive device is required. The structure is simple and compact, making it easy to integrate into the internal space of the cleaning head 200. Furthermore, this structure can automatically adjust the cutting frequency according to changes in the rotation speed of the cleaning component 100, adapting it to the hair cleaning needs of different usage scenarios.

[0103] Specifically, please refer to Figure 5 In this embodiment, one of the cutting portions 31 is fixedly installed on the base 10 and at least partially protrudes outward from the surface of the base 10; the first transmission mechanism 4 includes a sliding member 41, which is movably arranged relative to the base 10 along the axial direction and / or radial direction of the base 10; another cutting portion 31 is fixedly installed on the sliding member 41 and at least partially protrudes outward from the surface of the base 10.

[0104] Two cutting parts 31 are respectively installed on the base 10 of the cleaning part 100 and the sliding part 41. The rotational motion of the base 10 is converted into the reciprocating motion of the sliding part 41 through the first transmission mechanism 4, so as to realize the automatic cutting action between the two cutting parts 31.

[0105] This design not only fully utilizes the rotational power of the cleaning component 100 itself, avoiding the introduction of additional drive components, but also ensures good synchronization and stability of the cutting action. Through the flexible movement of the slider 41, an effective cutting angle can be formed between the two cutting sections 31, efficiently cutting hair entangled on the surface of the cleaning component 100 and preventing hair accumulation from affecting the cleaning effect. Furthermore, the design of the cutting section 31 protruding from the surface of the base 10 ensures that the cutting section 31 can effectively target the hair without losing its cutting ability due to excessive depth.

[0106] In one specific implementation, please refer to Figure 5 The slider 41 and the base 10 are provided with a guide structure that cooperates with each other to guide the slider 41 to perform controllable reciprocating motion in the axial direction or radial direction of the base 10.

[0107] Specifically, one of the base 10 and the slider 41 is provided with a guide groove 41a, and the other is provided with a guide portion 51 that matches the guide groove 41a. The guide portion 51 can be a protrusion, a pin, or other adaptable structure, which can be inserted into the guide groove 41a and slide along it.

[0108] When the base 10 rotates, the guide portion 51 rotates together with the cleaning component 100 and slides relative to it within the guide groove 41a. Due to the shape design of the guide groove 41a, such as an inclined groove, an arc groove, or a curved groove, the guide portion 51 generates a certain displacement component during its sliding process, pushing the slider 41 to move axially or radially, so as to convert the rotational motion of the base 10 into the linear or oscillating motion of the slider 41.

[0109] A cutting part 31 is mounted on the slider 41, so when it moves, the cutting part 31 will move relative to another cutting part 31 fixed on the base 10, forming a shearing stroke similar to scissors. The shearing action can continue during the rotation of the base 10, achieving efficient cutting of hair wrapped around its surface.

[0110] By providing a guide groove 41a and a guide portion 51 in a cooperating structure between the slider 41 and the base 10, the slider 41 can automatically generate reciprocating motion during the rotation of the cleaning part 100, thereby driving a shearing action between the two cutting portions 31. This mechanical linkage method is not only simple in structure and stable in operation, but also relies entirely on the rotational power of the base 10 itself, without the need to introduce an additional drive device, reducing energy consumption and manufacturing costs, and is suitable for a miniaturized spatial layout integrated into the cleaning head 200.

[0111] Specifically, the extension direction of the guide groove 41a is inclined to intersect the axial direction of the base 10, and the guide portion 51 extends radially along the base 10 and passes through the guide groove 41a.

[0112] The guide groove 41a is configured to intersect the axis of the cleaning component 100 at an angle, and the guide portion 51 extends radially along the cleaning component 100 and passes through it. This allows the sliding of the guide portion 51 within the guide groove 41a during the rotation of the cleaning component 100 to be naturally converted into axial displacement of the sliding member 41. This configuration, by utilizing the angular characteristics of the inclined guide groove 41a, converts rotational motion into linear motion, thereby driving the shearing action between the two cutting portions 31, achieving continuous and efficient cutting of hair on the surface of the cleaning component 100.

[0113] For more specific details, please refer to Figure 6 and Figure 7 In this embodiment, the first transmission mechanism 4 further includes a mounting shaft 5 extending along the axial direction of the base 10. One end of the mounting shaft 5 is fixedly connected to the housing 1 of the cleaning head 200, and the other end extends into the interior of the base 10, with a bearing 6 sleeved around it. The base 10 is connected to the outer ring of the bearing 6, so that the entire cleaning component 100 can rotate freely relative to the mounting shaft 5 under the action of the bearing 6.

[0114] A guide portion 51 extends outward from the side of the mounting shaft 5. This guide portion 51 can be a pin or a protrusion structure, and forms a sliding fit with the guide groove 41a provided on the sliding member 41. When the base 10 rotates with the bearing 6, the sliding member 41 and its guide groove 41a will also rotate. However, since the guide portion 51 is fixed on the mounting shaft 5, the guide portion 51 will slide relative to the guide groove 41a.

[0115] Because the guide groove 41a is inclined, the guide part 51 will generate a displacement component along the axis of the cleaning member 100 during its sliding process, which will push the sliding member 41 to move axially. A cutting part 31 is installed on the sliding member 41, and another cutting part 31 is fixed on the base 10 of the cleaning member 100. Therefore, the movement of the sliding member 41 will cause the two cutting parts 31 to form a scissor-like opening and closing action.

[0116] By introducing a structural combination of mounting shaft 5 and bearing 6 into the first transmission mechanism 4, and using the guide part 51 on the mounting shaft 5 and the guide groove 41a on the sliding member 41 for driving cooperation, the base 10 can automatically drive the sliding member 41 to generate axial displacement during its own rotation, thereby driving the two cutting parts 31 to form a shearing action.

[0117] This utility model also proposes a cleaning head 200, please refer to [link / reference]. Figures 8 to 11The cleaning head 200 includes a housing 1, a first cleaning component 2, and a second cleaning component 3. The specific structure of the second cleaning component 3 is as described in the above embodiments. Since this cleaning head 200 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, and will not be described in detail here. The housing 1 has a cavity 1a, and an inlet 1b and an outlet 1c communicating with the cavity 1a; the first cleaning component 2 is rotatably mounted on the cavity 1a; the second cleaning component 3 is used to clean or collect dirt on the first cleaning component 2.

[0118] During the cleaning process, the cleaning head 200 has an inlet 1b at its bottom, which is used to suck dust and debris from the floor, table, or bed into the internal cavity 1a. The first cleaning component 2 is installed in the cavity 1a inside the housing 1 and can rotate around its own axis to contact the surface being cleaned and perform cleaning. During the cleaning process, especially when cleaning carpets, beds, and other areas, hair or other fibrous materials can easily become entangled, affecting cleaning efficiency and even causing excessive motor load.

[0119] To address this issue, a second cleaning element 3 is provided on one side of the first cleaning element 2. In some embodiments, the first cleaning element 2 and the second cleaning element 3 are arranged side by side and at least partially in contact with each other. When the first cleaning element 2 rotates, the hair wrapped around its surface can be scraped off through the relative movement between it and the second cleaning element 3. This "relative movement" can be achieved in various ways: for example, the second cleaning element 3 can be fixed, it can rotate in the same direction as the first cleaning element 2 but at a different speed, or it can even rotate in opposite directions. As long as there is a certain speed difference or relative displacement between the two, the hair on the first cleaning element 2 can be effectively scraped off.

[0120] Besides direct contact, the second cleaning component 3 cleans or collects hair from the surface of the first cleaning component 2. In other embodiments, similar functions can be achieved in a non-contact state by rationally designing airflow, electrostatic adsorption, or mechanical scraping auxiliary structures.

[0121] Specifically, in one embodiment, the first cleaning component 2 is a rotating roller brush structure used to sweep the ground and collect dust and hair; the second cleaning component 3 is an airflow guiding structure or air duct assembly located behind it, which does not physically contact the first cleaning component 2. The second cleaning component 3 guides high-speed airflow past the vicinity of the first cleaning component 2 to form a local negative pressure or impact airflow, which blows away or sucks away the loosened hair and transports it to the dust collection system through the outlet 1c.

[0122] In another embodiment, the first cleaning component 2 is still a rotating roller brush structure, and its surface material has a certain electrostatic adsorption capacity, which is convenient for collecting light impurities such as hair; while the second cleaning component 3 is a non-contact electrostatic adsorption plate or electrode structure with opposite charge, located near the rotation path of the first cleaning component 2. The electrostatic field formed between the two causes hair to be adsorbed from the surface of the first cleaning component 2 and transferred to the second cleaning component 3, thereby achieving non-contact cleaning.

[0123] It should also be noted that in the cleaning head 200, the first cleaning element 2 and the second cleaning element 3 are structures that combine cleaning and self-cleaning functions.

[0124] The first cleaning component 2 is typically configured as a rotatable roller brush structure, which is installed along the internal cavity 1a of the housing 1 and driven by a drive device to rotate around its own axis. The surface of this roller brush is provided with bristles for sweeping dust, hair, and other debris from the ground and guiding the impurities to the inlet 1b into the cavity 1a. Because it is in direct contact with the ground, it is easily entangled by hair during operation, affecting cleaning efficiency and increasing the motor load.

[0125] The second cleaning element 3 can be a rotating element, a swinging element, or a reciprocating element, such as a small rotatable roller brush, an elastic scraper, or an eccentric swinging scraper. The second cleaning element 3 and the first cleaning element 2 form a shearing or scraping action, causing the hair wrapped around the first cleaning element 2 to be peeled off and discharged through the outlet 1c.

[0126] Understandably, during actual operation, although the second cleaning component 3 serves to clean the first cleaning component 2, because the second cleaning component 3 is in direct contact with hair, hair or other filaments originally scraped off from the first cleaning component 2 may also adhere to and gradually become entangled on the surface of the second cleaning component 3, which may itself become a new target for hair entanglement. If this is not effectively addressed, it will also affect the long-term operating efficiency of the cleaning head 200, and may even cause problems such as cleaning component jamming and motor overload.

[0127] By providing a cutting structure 30 on the second cleaning component 3, hair wrapped around its surface can be cut off in a timely manner, preventing hair accumulation. The cut hair is shorter and easier to detach, and is discharged into the dust collection box or other collection device through the outlet 1c, thereby avoiding blockage and motor overload.

[0128] This utility model also proposes a cleaning device, specifically, which can be a vacuum cleaner, sweeper, floor scrubber, mite remover, fabric cleaner, carpet cleaner, pet hair cleaner, handheld multi-functional cleaner, etc. The cleaning device includes a cleaning head 200, the specific structure of which is as described in the above embodiments. Since this cleaning device 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.

[0129] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
