Description

[0001] Priority information

[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 head and a cleaning device. Background Technology

[0004] As people's living standards continue to improve, more and more families are adopting cleaning equipment to automate daily environmental hygiene maintenance, such as robotic vacuum cleaners or multi-functional cleaning robots that combine sweeping and mopping. These devices typically have a cleaning component at the suction port to enhance the cleaning effect on dust and debris. However, in actual use, because the cleaning component is in direct contact with the ground, it is easily entangled by long, soft materials such as hair. When hair accumulates in large quantities on the cleaning component, it not only reduces the device's suction efficiency but may also hinder the normal rotation of the cleaning component, and in severe cases, even cause the motor to overload and stop, affecting the stable operation of the device and potentially shortening its lifespan. Currently, users mainly rely on manually removing the entangled material from the cleaning component periodically. This method is cumbersome, increases the user's burden, and affects the convenience and user experience of using the device. Utility Model Content

[0058] This utility model provides a cleaning head suitable for cleaning floors, tabletops, and beds. The cleaning head can be applied to household cleaning equipment such as vacuum cleaners, sweepers, floor scrubbers, mite removers, fabric cleaners, carpet cleaners, pet hair 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.

[0059] Please see Figure 1 , Figure 2 , Figure 8 and Figure 9 In the first embodiment of this utility model, the cleaning head 100 includes a housing 1 and two cleaning components. The housing 1 has a cavity 1a, and an inlet 1b and an outlet 1c communicating with the cavity 1a. The inlet 1b and the outlet 1c are arranged at an upward interval in front of and behind the housing 1. The two cleaning components are arranged side by side, and at least one of the cleaning components is rotatably mounted on the cavity 1a about its axis. The two cleaning components are at least partially in contact with each other, and at the position where the two cleaning components are in contact with each other, the two cleaning components are arranged in relative motion. One cleaning component is used to clean the hair on the other cleaning component during its rotation stroke. The two cleaning components include a first cleaning component 2 and a second cleaning component 3. The first cleaning component 2 is arranged corresponding to the inlet 1b, and the second cleaning component 3 is located behind the first cleaning component 2 and above the axis of the outlet 1c.

[0060] Specifically, the cleaning head 100 includes an inlet 1b for allowing dust, hair, and other debris to enter, and an outlet 1c for discharging these debris into a dust collection box or a vacuum system. These two openings are typically located at the bottom (near the surface being cleaned) and the rear (near the connection between the cleaning head 100 and the dust collection device main unit) of the housing 1.

[0061] It should be noted that inlet 1b is used to receive dust, hair and other debris from surfaces such as the ground, bed or table; outlet 1c uses the suction airflow to transport the collected debris to the dust collection device, thus achieving a closed loop of cleaning function.

[0062] Two cleaning components, designated as the first cleaning component 2 and the second cleaning component 3, are installed side-by-side inside the housing 1. The first cleaning component 2 is typically a rotatable roller brush structure, mounted along the internal cavity 1a of the housing 1 and driven to rotate around its own axis by a drive device. This roller brush has bristles on its surface for sweeping dust, hair, and other debris from the floor and guiding the impurities to the inlet 1b into the cavity 1a. Because it is in direct contact with the floor, it is easily entangled by hair during operation, affecting cleaning efficiency and increasing the motor load.

[0063] 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.

[0064] To enable one cleaning component to remove hair from the other during its rotational stroke, in some embodiments, the first cleaning component 2 and the second cleaning component 3 are at least partially in contact with each other. When the cleaning head 100 is operating, the two cleaning components rotate synchronously, generating relative motion in the contact area. For example, when the first cleaning component 2 rotates, its surface may become entangled with hair or other thin, flexible materials due to contact with the ground. At this time, because the second cleaning component 3 is in partial contact with it and rotates in the opposite direction or at a different speed, a shearing force can be generated at the contact point, thereby scraping off the hair on the first cleaning component 2 and preventing its accumulation from affecting cleaning performance. Conversely, the second cleaning component 3 can also achieve a self-cleaning function with the help of the first cleaning component 2.

[0065] The "relative motion" here can be achieved in various ways, such as the two rotating in opposite directions, at different speeds, or through sliding friction between the contact surfaces. For example, the second cleaning component 3 can be fixed, rotate in the same direction as the first cleaning component 2 but at a different speed, or 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 component 2 can be effectively scraped off.

[0066] It should also be noted that, in the specific implementation of the cleaning head protection, besides the direct contact method for the second cleaning component 3 to clean or collect hair from the surface of the first cleaning component 2, in other implementations, similar functions can be achieved in a non-contact state through the rational design of airflow, electrostatic adsorption, mechanical scraping auxiliary structures, etc.

[0067] Specifically, in one embodiment, the first cleaning component 2 is a rotating cleaning component 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.

[0068] In another embodiment, the first cleaning component 2 is still a rotating cleaning component 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.

[0069] The first cleaning component 2 is positioned near the inlet 1b and is primarily used to directly contact and sweep hair and dust from the floor. The second cleaning component 3 is located behind the first cleaning component 2, closer to the outlet 1c, and positioned above the axis of the outlet 1c. Hair that falls during the cleaning process will not fall back onto the uncleaned floor, avoiding secondary pollution caused by the cleaning action of the cleaning components and further improving the overall cleaning effect.

[0070] This layout places the contact area between the two cleaning components closer to the outlet 1c, rather than near the inlet 1b. When the first cleaning component 2 rotates, the hair attached to its surface is scraped off at the contact point with the second cleaning component 3 and falls off. Since this contact point is close to the outlet 1c, the hair can be quickly absorbed and carried away by the airflow at the outlet 1c, preventing it from accumulating or getting tangled again.

[0071] By enabling one cleaning component to effectively remove hair from the surface of another during rotation, this system avoids the problems of reduced suction efficiency, increased rotational resistance, and even motor stalling caused by hair entanglement in traditional cleaning equipment. Furthermore, the self-cleaning mechanism between the cleaning components eliminates the need for frequent manual cleaning, reducing maintenance costs and enhancing the ease of use and intelligence of the equipment. Simultaneously, the second cleaning component 3, located above the axis of outlet 1c, helps optimize airflow distribution, further improving the efficiency of dust and debris suction during the cleaning process.

[0072] Specifically, in this embodiment, the cleaning head 100 includes a first drive motor 8 that drives the second cleaning component 3 to rotate and a second drive motor 10 that drives the first cleaning component 2 to rotate. The first drive motor 8 is located above the second cleaning component 3 or behind the first cleaning component 2, and the second drive motor 10 is located inside the first cleaning component 2 or behind the first cleaning component 2.

[0073] Specifically, the cleaning head 100 is equipped with a first drive motor 8 and a second drive motor 10. The first drive motor 8 drives the second cleaning component 3 to rotate, and is preferably positioned above the second cleaning component 3 or behind the first cleaning component 2 to facilitate a compact spatial layout and overall structural balance. The second drive motor 10 drives the first cleaning component 2 to rotate; it can be embedded inside the first cleaning component 2 to form a built-in drive structure, or positioned on the rear exterior of the first cleaning component 2, using an external drive method.

[0074] By setting two independent motors to drive the two cleaning components respectively, the speed and direction of each cleaning component can be adjusted according to actual needs, thereby achieving a more flexible and efficient self-cleaning function. Since the first cleaning component 2 is usually more likely to come into contact with foreign objects such as hair on the ground, setting its motor to be built-in or close to the rear helps to reduce the external space occupation and improve the stability of the cleaning component's rotation; while placing the first drive motor 8 that drives the second cleaning component 3 above it or behind the first cleaning component 2 helps to maintain a balanced distribution of the power system within the housing 1, avoid local weight concentration, and facilitate heat dissipation and maintenance.

[0075] Furthermore, in this embodiment, the angular velocity of the second cleaning component 3 is set to be less than the angular velocity of the first cleaning component 2.

[0076] It should be noted that "angular velocity" refers to the speed at which the cleaning component rotates around its own axis.

[0077] To improve hair removal efficiency, the two cleaning components can rotate in the same direction, but their rotation speeds are different. Specifically, the first cleaning component 2, as the core component mainly responsible for cleaning surfaces such as floors and beds, rotates at a higher speed to quickly collect dust and hair; the second cleaning component 3 rotates at a lower angular velocity, so that there is a difference in tangential velocity between the two components during contact with the first cleaning component 2, thereby creating a relative sliding effect in the contact area.

[0078] For example, when the first cleaning component 2 rotates clockwise at high speed, the second cleaning component 3 also rotates clockwise. However, due to its smaller angular velocity, a certain relative motion rate will still be formed at the contact point between the two. This allows the hair attached to the surface of the first cleaning component 2 to be transferred more effectively to the second cleaning component 3, and further processed by the cutting structure 4 to prevent the hair from becoming entangled for a long time and affecting the cleaning performance.

[0079] Furthermore, by reasonably controlling the angular velocity difference between the two cleaning components, the adaptability of the cleaning head 100 to different types of hair (such as long hair, short hair, pet hair, etc.) can be adjusted, thereby improving the overall practicality and stability of the cleaning head 100.

[0080] Specifically, in one embodiment, the outer diameter of the cross-section of the second cleaning member 3 is set to be smaller than the outer diameter of the cross-section of the first cleaning member 2.

[0081] It should be noted that since the first cleaning component 2 is mainly used to directly contact the surfaces to be cleaned, such as the ground, bed, or table, and undertakes the main cleaning task, it needs a larger outer diameter to ensure good ground contact and cleaning efficiency. The main function of the second cleaning component 3 is to assist in removing hair from the first cleaning component 2 and to work with the cutting structure 4 to complete the hair removal work; therefore, it does not need to have the same size as the first cleaning component 2.

[0082] By designing the outer diameter of the second cleaning component 3 to be smaller, more space can be reserved for the layout of its surrounding components and housing 1 without reducing cleaning performance. This facilitates a compact design of the overall structure of the cleaning head 100, which is especially suitable for household cleaning equipment with high space requirements, such as robot vacuum cleaners and handheld vacuum cleaners.

[0083] In addition, the smaller size of the second cleaning component 3 results in a smaller moment of inertia, making it easier to respond to the actions of the drive components and improving the efficiency of collaborative work with the first cleaning component 2.

[0084] Specifically, in this embodiment, the hardness of the material on the surface of the second cleaning component 3 is set to be greater than the hardness of the material on the surface of the first cleaning component 2.

[0085] Here, "hardness" refers to a material's ability to resist external forces penetrating its surface, and is usually measured using Shore hardness or other common hardness standards. In the field of cleaning equipment, soft materials (such as rubber or elastic polymers) are commonly used on the surface of cleaning parts to improve adhesion and cleaning effect on surfaces such as floors and beds; however, if used for shaving hair, a material with a certain degree of hardness is required to effectively peel hair attached to another cleaning part.

[0086] Therefore, in this utility model, the first cleaning component 2 is mainly responsible for directly contacting the surfaces to be cleaned, such as the ground, bed, and table. To improve its adhesion and cleaning efficiency, its surface is usually made of a softer material, such as soft rubber or a brush structure with a certain degree of elasticity. The second cleaning component 3 is mainly used to scrape the hair off the first cleaning component 2. To enhance its scraping ability, its surface material is made of a harder material, such as hard rubber, plastic, or a structure with rigid brush strips.

[0087] When the first cleaning component 2 rotates and comes into contact with the second cleaning component 3, the second cleaning component 3, being made of a harder material, can effectively peel off the hair attached to the surface of the first cleaning component 2 during the relative movement of the two components, thereby preventing hair accumulation from affecting the cleaning effect.

[0088] More specifically, the second cleaning component 3 includes at least a portion of a hard-bristled brush, a soft rubber component, or soft bristles, while the first cleaning component 2 is a soft-bristled brush with soft bristles.

[0089] Considering the different functional roles of the first cleaning component 2 and the second cleaning component 3 in the cleaning head 100, the first cleaning component 2 utilizes a soft material to enhance its adaptability and cleaning effect on various floor or fabric surfaces, and is especially suitable for handling complex surfaces such as carpets and beds; while the second cleaning component 3 includes at least a hard brush, soft rubber parts or soft fluff, and has a high degree of hardness, which can effectively scrape off the hair tangled on the surface of the first cleaning component 2 during contact, preventing hair accumulation from causing blockage or increased motor load.

[0090] Specifically, in this embodiment, the first cleaning component 2 and the second cleaning component 3 have the same turning direction.

[0091] In other words, when the cleaning head 100 is working, both cleaning components rotate in the same direction, such as simultaneously rotating clockwise or simultaneously rotating counterclockwise. In the contact area, the linear velocity of the first cleaning component 2 at the contact point is downward, while the linear velocity of the second cleaning component 3 at the same position is upward. The two form a significant relative sliding speed, which can enhance the transfer effect of hair from the first cleaning component 2 to the second cleaning component 3, and achieve more efficient hair removal.

[0092] In actual operation, although the second cleaning component 3 serves to clean the first cleaning component 2, it also rotates and comes into direct contact with hair. Therefore, hair or other filaments that were originally scraped off from the first cleaning component 2 may 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 100, and may even cause problems such as the cleaning component jamming or the motor overload.

[0093] Furthermore, for better cleaning of hair on the second cleaning component 3, please refer to... Figures 3 to 6 In this embodiment, the cleaning head 100 further includes a cutting structure 4 disposed in the cavity 1a, the cutting structure 4 being used to cut hair wrapped around the second cleaning member 3. The cutting structure 4 is used to cut off hair that may be wrapped around the second cleaning member 3, preventing tangling, shortening its length, and facilitating its discharge from the outlet 1c and into the dust collection box or other collection device.

[0094] Understandably, during the cleaning process, the first cleaning component 2 is primarily responsible for contacting the surfaces being cleaned, such as floors, beds, and tabletops, to remove dust, hair, and other debris. It is the core component of the cleaning head 100, enabling it to perform basic cleaning functions. Therefore, the structural design of the first cleaning component 2 should be as simple and lightweight as possible to ensure good rotational performance and good adhesion to the floor. Integrating the cutting structure 4 into the first cleaning component 2 would not only increase its weight and structural complexity but may also affect its cleaning efficiency and operational stability.

[0095] It would be more reasonable to place the cutting structure 4 inside the second cleaning component 3. When the first cleaning component 2 rotates, the relative movement between it and the adjacent second cleaning component 3 can scrape off the hair on the first cleaning component 2 and transfer it to the surface of the second cleaning component 3. At this time, since the cutting structure 4 is embedded in the second cleaning component 3, it can cut the hair wrapped around its surface in time, preventing hair accumulation. The cut hair is shorter and easier to fall off, and is discharged into the dust collection box or other collection device through the outlet 1c.

[0096] Thus, the design of integrating the cutting structure 4 into the second cleaning component 3 not only saves space inside the housing 1, but also helps to achieve a more compact overall structural design, facilitating the miniaturization and weight reduction of the cleaning head 100.

[0097] It should be noted that the cutting structure 4 can be composed of micro blades, cutting teeth or other components with shearing capabilities, arranged near the root of the bristles 31, and its reasonable arrangement ensures that it can still perform a good cutting effect during rotation.

[0098] More specifically, the cutting structure 4 is installed inside the second cleaning component 3. The cutting structure 4 includes two cooperating cutting portions 41, each of which extends along the axial direction of the second cleaning component 3. The two cutting portions 41 are movably arranged relative to each other in the axial direction and / or radial direction of the second cleaning component 3 to cut hair wrapped around the second cleaning component 3.

[0099] Specifically, the cutting structure 4 includes two cutting portions 41 that can cooperate to perform a cutting action. These two cutting portions 41 extend along the axial direction of the second cleaning component 3, and at least one cutting portion 41 can be movably positioned relative to the other cutting portion 41 in the axial or radial direction. This allows relative movement between the two cutting portions 41, thereby creating a "cutting" effect similar to scissors, cutting off the hair wrapped around the surface of the second cleaning component 3, and preventing it from continuing to accumulate and affecting the normal operation of the cleaning component.

[0100] The two cutting sections 41 can be fixed at different positions on the second cleaning member 3, for example, one can be fixed while the other can slide within a certain range; or both can be movable, moving closer or further apart via an elastic element or drive mechanism. When the second cleaning member 3 is configured to rotate, the hair wrapped around its surface is guided to the area between the two cutting sections 41. At this time, due to the relative movement between the two cutting sections 41, they apply a shearing force to the hair at the contact point, cutting the hair.

[0101] It should be noted that the relative range of motion between the two cutting sections 41 can be adjusted according to actual needs to adapt to hair entanglement of different thicknesses or densities, thereby improving the applicability and stability of the cleaning head 100.

[0102] To achieve the aforementioned shearing function, the cleaning head 100 also includes a first transmission mechanism 5, which is disposed between the second cleaning member 3 and the two cutting sections 41. Its function is to convert the rotational motion of the second cleaning member 3 into the relative motion stroke between the two cutting sections 41. For example, when the second cleaning member 3 rotates, the transmission mechanism can drive one of the cutting sections 41 to slide or swing relative to the other cutting section 41, thereby generating a shearing force.

[0103] Specifically, the first transmission mechanism 5 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 second cleaning component 3 into a periodic cutting action, so that the two cutting parts 41 continuously open and close during the rotation of the cleaning component, and continuously perform efficient cutting treatment on the hair wrapped around its surface.

[0104] Since the shearing action between the two cutting sections 41 is driven by the rotation of the second cleaning component 3 itself, no additional motor or drive device is required. The structure is simple, compact, and easy to integrate into the internal space of the cleaning head 100. Furthermore, this structure can automatically adjust the shearing frequency according to changes in the rotation speed of the cleaning component, adapting it to the hair cleaning needs of different usage scenarios.

[0105] For details, please continue reading Figures 3 to 6 In this embodiment, the second cleaning member 3 includes a base 32 and bristles 31 mounted on the periphery of the base 32. One of the cutting portions 41 is fixedly mounted on the base 32 and at least partially protrudes outward from the surface of the base 32. The first transmission mechanism 5 includes a sliding member 51, which is movably disposed relative to the base 32 along the axial direction and / or radial direction of the second cleaning member 3. Another cutting portion 41 is fixedly mounted on the sliding member 51 and at least partially protrudes outward from the surface of the base 32.

[0106] Two cutting parts 41 are respectively installed on the base 32 of the second cleaning part 3 and the sliding part 51, and the rotational motion of the cleaning part is converted into the reciprocating motion of the sliding part 51 through the first transmission mechanism 5, so as to realize the automatic cutting action between the two cutting parts 41.

[0107] This design not only fully utilizes the rotational power of the second cleaning component 3, avoiding the introduction of additional driving components, but also ensures good synchronization and stability of the cutting action. Through the flexible movement of the slider 51, an effective cutting angle can be formed between the two cutting sections 41, efficiently cutting hair entangled on the surface of the cleaning component and preventing hair accumulation from affecting the cleaning effect. Furthermore, the design of the cutting section 41 protruding from the surface of the base 32 ensures that the cutting section 41 can effectively target the hair without losing its cutting ability due to excessive depth.

[0108] In one specific embodiment, a guide structure is provided between the sliding member 51 and the second cleaning member 3 to guide the sliding member 51 to perform controllable reciprocating motion in the axial direction or radial direction of the second cleaning member 3.

[0109] Specifically, the base 32 of the second cleaning member 3 and the sliding member 51 are provided with a guide groove 51a, and the other is provided with a guide portion 61 that matches the guide groove 51a. The guide portion 61 can be a protrusion, a pin, or other adaptable structure, which can be inserted into the guide groove 51a and slide along it.

[0110] When the second cleaning component 3 rotates, the guide portion 61 rotates with the cleaning component and slides relative to it within the guide groove 51a. Due to the shape design of the guide groove 51a, such as an inclined groove, an arc groove, or a curved groove, the guide portion 61 generates a certain displacement component during its sliding process, pushing the slider 51 to move axially or radially, so as to convert the rotational motion of the second cleaning component 3 into the linear or oscillating motion of the slider 51.

[0111] A cutting part 41 is mounted on the slider 51, so when it moves, the cutting part 41 will move relative to another cutting part 41 fixed on the base 32, forming a shearing stroke similar to scissors. The shearing action can continue during the rotation of the second cleaning member 3, achieving efficient cutting of hair wrapped around its surface.

[0112] By providing a guide groove 51a and a guide portion 61 between the slider 51 and the second cleaning component 3, the slider 51 can automatically generate reciprocating motion during the rotation of the cleaning component, thereby driving the two cutting portions 41 to form a shearing action. This mechanical linkage method is not only simple in structure and stable in operation, but also relies entirely on the rotational power of the second cleaning component 3 itself, without the need to introduce an additional drive device, reducing energy consumption and manufacturing costs, and is suitable for the miniaturized spatial layout of the cleaning head 100.

[0113] Specifically, the extension direction of the guide groove 51a is inclined to intersect the axial direction of the second cleaning member 3, and the guide portion 61 extends radially along the second cleaning member 3 and passes through the guide groove 51a.

[0114] The guide groove 51a is configured to intersect the axis of the cleaning component at an angle, and the guide portion 61 extends radially along the cleaning component and passes through it. This allows the sliding of the guide portion 61 within the guide groove 51a during the rotation of the cleaning component to be naturally converted into axial displacement of the sliding member 51. This configuration, by utilizing the angular characteristics of the inclined guide groove 51a, converts rotational motion into linear motion, thereby driving the shearing action between the two cutting portions 41 and achieving continuous and efficient cutting of hair on the surface of the second cleaning component 3.

[0115] For more specific details, please refer to Figures 4 to 6 In this embodiment, the first transmission mechanism 5 further includes a mounting shaft 6 extending along the axis of the second cleaning component 3. One end of the mounting shaft 6 is fixedly connected to the housing 1 of the cleaning head 100, and the other end extends into the interior of the second cleaning component 3, with a bearing 7 sleeved around it. The base 32 of the second cleaning component 3 is connected to the outer ring of the bearing 7, so that the entire cleaning component can rotate freely relative to the mounting shaft 6 under the action of the bearing 7.

[0116] A guide portion 61 extends outward from the side of the mounting shaft 6. This guide portion 61 can be a pin or a protrusion structure, and forms a sliding fit with the guide groove 51a provided on the sliding member 51. When the second cleaning member 3 rotates with the bearing 7, the sliding member 51 and its guide groove 51a also rotate. However, since the guide portion 61 is fixed on the mounting shaft 6, the guide portion 61 will slide relative to the guide groove 51a.

[0117] Because the guide groove 51a is inclined, the guide part 61 will generate a displacement component along the axis of the cleaning part during its sliding process, which will push the slider 51 to move axially. A cutting part 41 is installed on the slider 51, and another cutting part 41 is fixed on the base 32 of the cleaning part. Therefore, the movement of the slider 51 will cause the two cutting parts 41 to form a scissor-like opening and closing action.

[0118] By introducing a structural combination of mounting shaft 6 and bearing 7 into the first transmission mechanism 5, and using the guide part 61 on the mounting shaft 6 and the guide groove 51a on the sliding member 51 for driving cooperation, the second cleaning member 3 can automatically drive the sliding member 51 to generate axial displacement during its own rotation, thereby driving the two cutting parts 41 to form a shearing action.

[0119] Specifically, in the first embodiment, each of the cutting portions 41 includes a blade that extends continuously along the axial direction of the second cleaning member 3 and does not protrude from the axial end face of the second cleaning member 3.

[0120] Specifically, the blade is embedded entirely inside or near the surface of the second cleaning element 3, and its two ends do not extend beyond the axial end face of the cleaning element, i.e., they do not protrude outwards. This allows the blade to uniformly cut the hair wrapped around its surface along the entire length of the cleaning element.

[0121] In the second embodiment, each of the cutting portions 41 includes a plurality of blades spaced apart in the axial direction of the second cleaning member 3, so as to reduce the amount of material used while maintaining good shearing performance.

[0122] Further, in this embodiment, the second cleaning member 3 includes a base 32 and bristles 31 installed around the base 32. The cutting structure 4 is installed on the base 32 and protrudes outward from the base 32 along the radial direction of the second cleaning member 3. The maximum radial distance between the cutting structure 4 and the central axis of the base 32 is d1, and the maximum radial distance between the bristles 31 and the central axis of the base 32 is d2, where d2 > d1.

[0123] It should be noted that "maximum radial distance" refers to the maximum straight-line distance between the outermost point of a structure (such as bristle 31 or cutting structure 4) and its rotation center of the second cleaning component 3. This distance is measured from the geometric center of the cleaning component along a direction perpendicular to the axis of the cleaning component to the outermost position of the structure.

[0124] Specifically: d1 refers to the maximum radial distance between the cutting structure 4 and the central axis of the base 32 of the second cleaning element 3 to its outermost edge; d2 refers to the maximum radial distance between the bristles 31 and the central axis of the base 32 of the second cleaning element 3 to its outermost end.

[0125] Setting d2 to be greater than d1 means that although the cutting structure 4 protrudes outward, its position is always inside the bristles 31. During the process of the second cleaning component 3 and the first cleaning component 2 approaching and making contact, the bristles 31 always contact the first cleaning component 2 first, while the cutting structure 4 is "protected" inside by the bristles 31 and will not directly contact the surface of the first cleaning component 2 or the bristles 31. Even if, during actual operation, the bristles 31 undergo slight deformation due to the rotation of the cleaning component, pressure changes, or uneven ground, the cutting structure 4 will not accidentally contact the first cleaning component 2, thus effectively preventing accidental damage to the first cleaning component 2 due to the cutting structure 4.

[0126] Specifically, in this embodiment, 1mm ≤ d2 - d1 ≤ 3mm. Preferably, 1.5mm ≤ d2 - d1 ≤ 2mm.

[0127] It should be noted that if the radial distance difference between the bristles 31 and the cutting structure 4 is too small, such as less than 1 mm, the cutting structure 4 may be accidentally exposed and come into contact with the first cleaning component 2 when the bristles 31 are deformed, causing accidental cutting of the surface of the first cleaning component 2, resulting in wear or even jamming; while if the distance difference is too large, such as more than 3 mm, the cutting structure 4 may be far from the outer surface of the cleaning component, affecting its cutting efficiency for tangled hair.

[0128] Therefore, by controlling the distance difference between 1 and 3 mm, and further optimizing it to between 1.5 and 2 mm, it is possible to ensure good shearing effect while effectively avoiding unnecessary interference between the cutting structure 4 and the first cleaning component 2, thus achieving the best balance between cleaning efficiency and safety.

[0129] In the second embodiment provided by this utility model, the cleaning head 100 includes a housing 1, two cleaning components and a drive assembly. The two cleaning components are at least partially in contact with each other. One of the cleaning components is used to clean hair on the other cleaning component during its rotation stroke. The drive assembly is disposed in the housing 1 and is used to drive at least one of the two cleaning components to rotate. The two cleaning components include a first cleaning component 2 located in front of the cleaning head 100 along the forward direction and a second cleaning component 3 located behind and above the first cleaning component 2. The second cleaning component 3 is provided with a cutting structure 4 for cutting hair wrapped around the second cleaning component 3.

[0130] By placing a second cleaning component 3 behind the first cleaning component 2 in the forward direction of the cleaning head 100, and enabling relative movement between the two in the contact area, hair entangled on the surface of the first cleaning component 2 is effectively removed. This achieves self-cleaning capability of the cleaning equipment during operation, reducing the frequency of manual cleaning by the user. Since the second cleaning component 3 is positioned behind the cleaning head 100 in the forward direction, hair that falls during cleaning will not fall back onto the uncleaned ground, avoiding secondary pollution caused by the cleaning action of the cleaning component and further improving the overall cleaning effect. Furthermore, the second cleaning component 3 promptly removes any entangled material from the first cleaning component 2, maintaining its normal rotation, reducing motor load, and preventing stalling.

[0131] In actual operation, although the second cleaning component 3 serves to clean the first cleaning component 2, it also rotates and comes into direct contact with hair. Therefore, hair or other filaments that were originally scraped off from the first cleaning component 2 may 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 100, and may even cause problems such as the cleaning component jamming or the motor overload.

[0132] The second cleaning component 3 is provided with a cutting structure 4 for cutting hair that is wrapped around it. The cutting structure 4 is used to cut the hair that may be wrapped around the second cleaning component 3, so as to avoid tangling and shorten its length, making it easier to be discharged from the outlet 1c and enter the dust collection box or other collection device.

[0133] Understandably, during the cleaning process, the first cleaning component 2 is primarily responsible for contacting the surfaces being cleaned, such as floors, beds, and tabletops, to remove dust, hair, and other debris. It is the core component of the cleaning head 100, enabling it to perform basic cleaning functions. Therefore, the structural design of the first cleaning component 2 should be as simple and lightweight as possible to ensure good rotational performance and good adhesion to the floor. Integrating the cutting structure 4 into the first cleaning component 2 would not only increase its weight and structural complexity but may also affect its cleaning efficiency and operational stability.

[0134] It would be more reasonable to place the cutting structure 4 inside the second cleaning component 3. When the first cleaning component 2 rotates, the relative movement between it and the adjacent second cleaning component 3 can scrape off the hair on the first cleaning component 2 and transfer it to the surface of the second cleaning component 3. At this time, since the cutting structure 4 is embedded in the second cleaning component 3, it can cut the hair wrapped around its surface in time, preventing hair accumulation. The cut hair is shorter and easier to fall off, and is discharged into the dust collection box or other collection device through the outlet 1c.

[0135] Thus, the design of integrating the cutting structure 4 into the second cleaning component 3 not only saves space inside the housing 1, but also helps to achieve a more compact overall structural design, facilitating the miniaturization and weight reduction of the cleaning head 100.

[0136] In this embodiment, the specific structure of the cleaning head 100 includes at least one or more specific embodiments of the first embodiment of the present invention, which will not be described in detail here.

[0137] This utility model also proposes a cleaning device. Specifically, the cleaning device 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 100. The specific structure of the cleaning head 100 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.

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.
