Description

Technical Field

[0001] This invention relates to the field of vacuum cleaner technology, specifically to a rotating metal blade comb structure for a vacuum cleaner floor brush. Background Technology

[0002] A vacuum cleaner is a cleaning appliance that uses a motor to drive blades to rotate at high speed, creating negative air pressure inside a sealed housing, thereby sucking dust and debris into a dust collection device, and expelling the filtered air at extremely high speed. Vacuum cleaners are classified according to their function into dry vacuum cleaners and wet / dry vacuum cleaners. Dry vacuum cleaners generally include dust bag type and dust cup type.

[0003] Current vacuum cleaners are often plagued by hair entanglement during operation, and there is no effective solution. During use, the brush assembly on the roller brush picks up dust and hair from the floor and cleaning surface. However, under the influence of airflow and other factors, the hair gradually extends and tangles within the brush assembly, making subsequent roller brush cleaning extremely difficult. Some vacuum cleaners incorporate hair cutting and brush assembly combing mechanisms to improve the hair entanglement problem, typically using cutters or scrapers. However, this design cannot effectively and stably capture and grip the hair; insufficient tension at the hair ends causes the hair to slide on the cutters or scrapers, failing to achieve adequate cutting and combing. Commonly, cutters or scrapers cut directly into the brush assembly, damaging it and affecting the roller brush's suction and cleaning efficiency. Due to the complexity of the entangled hair, some of the cut, fine hair fragments become embedded within the brush assembly, unable to be sucked, scraped, or removed by airflow or the combing mechanism, making subsequent roller brush cleaning even more difficult. Summary of the Invention

[0004] The purpose of this invention is to solve the common problems of difficult hair removal from floor brushes, where some combing and cutting mechanisms cannot guarantee the efficiency and extent of hair removal, and may also damage the brush assembly and affect the use of the roller brush. Therefore, this invention provides a rotating metal blade comb structure for a vacuum cleaner floor brush.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rotating metal blade comb structure for a vacuum cleaner floor brush, comprising:

[0006] A hair cutting mechanism, which is located inside the main body of the floor brush and on the side of the roller assembly, includes a metal blade link and a plurality of metal blade comb teeth spaced apart on the metal blade link;

[0007] Among them, the metal blade comb teeth are centrally symmetrically distributed along the surface of the metal blade connecting rod, and the extension direction of the metal blade comb teeth is the same as the rotation direction of the metal blade connecting rod;

[0008] The metal blade link is associated with the drive mechanism of the rolling assembly, and the metal blade comb teeth are driven to rotate in the opposite direction to the rolling assembly;

[0009] The metal blade comb cleans the hair on the brush assembly of the roller assembly;

[0010] A hair grasping mechanism, which is located upstream of the rotation direction of the roller assembly relative to the hair cutting mechanism, includes a first comb plate and a gripper assembly, a guide assembly, and a linkage assembly arranged sequentially along the surface of the first comb plate and toward the roller assembly.

[0011] The gripper assembly is slidably disposed on the first comb plate;

[0012] A pressing block is provided on the linkage component facing the guide component, and the pressing block is associated with the gripper component;

[0013] A hair adsorption mechanism, which is disposed within the body of the floor brush and extends radially along the roller assembly, includes a second comb plate and an adsorption element disposed on the second comb plate;

[0014] Among them, the hair adsorption mechanism can be arranged in multiple ways along the inner wall of the roller brush cavity of the main body of the floor brush and the circumference of the roller assembly.

[0015] The aforementioned hair-grabbing mechanism and hair-cutting mechanism are both located above the air outlet of the roller brush cavity of the main body of the floor brush.

[0016] As a further description of the above technical solution:

[0017] The drive mechanism includes two gears that connect the rotating shaft of the drive device and the rolling assembly, and the two gears are meshed together.

[0018] A drive gear extends coaxially from the gear on the drive device, and a driven gear extends coaxially from the metal blade connecting rod. The drive gear and the driven gear are driven together by a conveyor belt.

[0019] Of course, the drive mechanism can also adopt a multi-gear set structure. In this case, the drive gear should be set on a gear that is an even number of gears away from the gear connecting the rolling element assembly (the even number of gears mesh with the gear connecting the rolling element assembly one by one).

[0020] As a further description of the above technical solution:

[0021] The first comb plate includes a first base plate mounted on the brush body and a first mounting plate spaced on the first base plate and extending toward the roller assembly;

[0022] The first clearance groove between the first mounting plates corresponds to the metal blade comb teeth;

[0023] The gripper assembly, guide assembly, and linkage assembly are mounted on the first mounting plate.

[0024] As a further description of the above technical solution:

[0025] The gripper assembly includes a hinge seat and a gripper block hinged to the hinge seat via a hinge shaft;

[0026] A torsion spring is provided on the hinge shaft, and the torsion spring is elastically pre-tightened to connect the hinge seat and the clamping block;

[0027] The torsion spring generates a preload force on the clamping block to rotate toward the hinge seat. The torsion spring can also be replaced by a tension spring, with the end of the tension spring connecting the hinge seat and the clamping block.

[0028] As a further description of the above technical solution:

[0029] The guide component extends an arc-shaped guide slope toward the linkage component, and the guide component forms a limiting block toward the clamping block.

[0030] The bottom of the clamping block is provided with a positioning groove corresponding to the limiting block.

[0031] As a further description of the above technical solution:

[0032] The linkage component includes a housing and an electrical component disposed within the housing;

[0033] The electrical components and the housing are equipped with touch switches corresponding to the pressing blocks;

[0034] The pressing block is elastically slidably disposed at the opening of the box body;

[0035] The pressing block has a stepped structure, and a retaining ring is provided on the outside of the opening of the box. The outside of the pressing block abuts against the inside of the retaining ring. A ring-shaped elastic element is provided between the retaining ring, the inner wall of the box and the pressing block, thereby ensuring one-dimensional sliding of the pressing block.

[0036] As a further description of the above technical solution:

[0037] The gripper assembly has a slide block at its bottom, which is slidably connected to the guide groove of the first comb plate. A reset elastic element is provided between the slide block and the guide groove.

[0038] The reset elastic element generates an elastic preload force on the slide block that is opposite to the linkage assembly.

[0039] As a further description of the above technical solution:

[0040] An electromagnet electrically associated with the electrical component is disposed in the guide groove of the first comb plate;

[0041] The slide is provided with a magnet corresponding to the electromagnet.

[0042] As a further description of the above technical solution:

[0043] The second comb plate includes a second base plate mounted on the brush body and a second mounting plate spaced on the second base plate and extending toward the roller assembly;

[0044] The second clearance groove between the second mounting plates corresponds to the metal blade comb teeth;

[0045] The adsorption element is disposed at the end of the second mounting plate.

[0046] As a further description of the above technical solution:

[0047] A discharge module is installed inside the second comb plate;

[0048] The discharge module is electrically connected to a time relay;

[0049] The discharge module passes through the second comb plate via a conductive medium and connects to the adsorption element.

[0050] The discharge module emits positively or negatively charged particles to the adsorption element according to a set time interval.

[0051] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0052] 1. This invention uses a hair-grabbing mechanism to grasp hair on the brush assembly in a coordinated manner, ensuring sufficient and stable tension at the ends. Then, a hair-cutting mechanism rotates in opposite directions relative to the roller brush assembly, and metal blades cut the hair grasped by the hair-grabbing mechanism. This reduces the length and complexity of hair within the brush assembly, and the resulting difficulty in hair pulling and detachment from the brush assembly. Subsequently, the hair adsorption mechanism within the roller brush cavity of the main body of the floor brush performs reciprocating detachment treatment on the brush assembly by adsorption components. This improves the cleaning efficiency of the hair on the roller brush and avoids the problem of subsequent cleaning difficulties caused by densely entangled hair on the brush assembly during use. By pulling out the hair from the brush assembly through the hair-grabbing mechanism and then cutting it, compared to the common structure and method of blades and scrapers directly contacting the brush to cut the hair, damage to the brush assembly is reduced, ensuring its adsorption efficiency for dust and hair on the ground.

[0053] 2. During use, as the roller assembly rotates, the first comb plate combs the brush assembly. The hair comes into contact with the guide assembly and is guided to the linkage assembly. The hair is pressed onto the pressing block, causing it to move inward and triggering the switch. This causes the electrical component to supply power to the electromagnet, creating a magnetic field around the electromagnet and generating a magnetic attraction force on the magnet. The magnetic attraction force drives the slide to move along the guide groove toward the electromagnet, where the magnet and electromagnet align, and the slide is positioned. During this process, the hinge seat moves synchronously with the slide, and the clamping block moves along the surface of the guide assembly. The elastic preload formed by the torsion spring or tension spring on the clamping block as it rotates toward the guide assembly, working in conjunction with the guide assembly and linkage assembly to clamp the hair. The rotating metal blade comb teeth comb through the hair... After cutting, the tension at the hair tip is released, causing the hair to detach from the pressing block due to the centrifugal force generated by the airflow and the rotation of the component. The pressing block resets, the touch switch switches to the off state, the electromagnet loses its magnetism, and the reset elastic element drives the gripper assembly to reset, thus completing the hair grabbing and cutting operation. After cutting, the fine hair fragments are either directly discharged from the air outlet of the brush body by the airflow after cutting, or remain on the brush assembly and continue to roll through the roller assembly. The hair adsorption mechanism adsorbs the fine hair fragments on the brush assembly, causing them to detach from the brush assembly. Then, the fine hair fragments on the adsorption element are detached again under the action of the external airflow and discharged from the air outlet of the brush body for unified collection of hair and dust.

[0054] 3. The mechanism by which the adsorption element works on fine hair lies in the fact that the discharge module periodically transfers charged particles to the adsorption element through a conductive medium, making it charged and thus adsorbing the hair. During this process, charged particles with opposite charges are alternately transferred to neutralize the charge, making the adsorption element electrically neutral. This design achieves hair adsorption when the adsorption element is charged, hair desorption from the brush assembly, and hair desorption through airflow guidance when electrically neutral, with the hair exiting through the air outlet of the brush body for unified collection.

[0072] Example 1:

[0073] Please see Figure 1 —7. This invention provides a technical solution: a rotating metal blade comb structure for a vacuum cleaner floor brush, comprising:

[0074] A hair cutting mechanism, which is disposed inside the brush body 100 and located on the side of the roller assembly 200, includes a metal blade connecting rod 11 and a plurality of metal blade comb teeth 1 spaced apart on the metal blade connecting rod 11.

[0075] The metal blade comb teeth 1 are centrally symmetrically distributed along the surface of the metal blade connecting rod 11, and the extension direction of the metal blade comb teeth 1 is the same as the rotation direction of the metal blade connecting rod 11. This ensures that the metal blade comb teeth 1 efficiently cuts and shreds the hair extracted from the roller assembly 200, so that the subsequent comb tooth structure can scrape off the hair fragments. This avoids the problem of hair being difficult to pull out due to excessive extension within the brush assembly 210. In addition, the internal negative pressure fully collects the hair, improves the cleanliness of the brush assembly 210, and reduces the cleaning frequency.

[0076] The metal blade connecting rod 11 is associated with the drive mechanism of the roller assembly 200, and the metal blade comb teeth 1 and the roller assembly 200 are driven to rotate in opposite directions. This design increases the contact frequency between the metal blade comb teeth 1 and the hair, as well as the cutting force during cutting, while reducing the use of drive equipment, reducing costs and energy consumption, and reducing space occupation. This makes the vacuum cleaner floor brush design more compact and fully functional, and easier to transport, store, and use.

[0077] The metal blade comb 1 cleans the hair on the brush assembly 210 of the roller assembly 200;

[0078] The hair grasping mechanism is located upstream of the rotation direction of the roller assembly 200 relative to the hair cutting mechanism, and includes a first comb plate 2 and a gripper assembly 3, a guide assembly 4, and a linkage assembly 5 arranged sequentially along the surface of the first comb plate 2 and toward the roller assembly 200.

[0079] This design allows for stable gripping of the hair before the metal blade comb 1 cuts it, preventing the hair from slipping on the metal blade comb 1 due to insufficient tension at both ends.

[0080] The gripper assembly 3 is slidably mounted on the first comb plate 2; this design facilitates the adjustment of the position of the gripper assembly 3 at the guide assembly 4 and the linkage assembly 5, so as to achieve efficient switching between the gripping state and the releasing state of the comb structure.

[0081] A pressing block 52 is provided on the linkage component 5 facing the guide component 4, and the pressing block 52 is associated with the gripper component 3;

[0082] The guide component 4 is used to pull and guide the hair on the brush component 210 when it passes the first comb plate 2, so that it moves to the linkage component 5. The hair presses the pressing block 52, thereby linking the gripper component 3 to cooperate with the guide component 4 and the linkage component 5 to grip the hair, so as to ensure the stable tension at the hair end and make the metal blade comb teeth 1 cut more fully.

[0083] In order to improve the removal efficiency of fine hairs cut by the metal blade comb 1 on the brush assembly 210, the floor brush of this vacuum cleaner is also provided with a component for hair adsorption. Specifically, it is designed as a hair adsorption mechanism, which is disposed in the floor brush body 100 and extends radially along the roller assembly 200, including a second comb plate 6 and an adsorption element 7 disposed on the second comb plate 6.

[0084] The hair adsorption mechanism can be arranged in multiple ways along the inner wall of the roller brush cavity of the floor brush body 100 and the circumference of the roller assembly 200 to ensure sufficient adsorption of hair on the brush assembly 210, improve the cleanliness of the floor brush body 100, and enhance the user's convenience and experience.

[0085] The aforementioned hair-grabbing mechanism and hair-cutting mechanism are both located above the air outlet of the roller brush cavity of the floor brush body 100. This allows the hair detached from the brush assembly 210 at this location to be discharged from the air outlet and collected due to gravity and airflow at the outlet. This prevents hair fragments from falling back onto the ground or the inner wall of the roller brush cavity of the floor brush body 100, thus avoiding problems such as dirt collection, low cleaning efficiency, and low cleanliness of the vacuum cleaner floor brush due to contamination, thereby improving usage efficiency.

[0086] This invention uses a hair-grabbing mechanism to grasp hair on the brush assembly 210, ensuring sufficient and stable tension at the ends. Then, a hair-cutting mechanism rotates in opposite directions relative to the roller brush assembly 200, and the metal blade comb 1 cuts the hair grasped by the hair-grabbing mechanism. This reduces the length and complexity of hair within the brush assembly 210, and the resulting difficulty in hair pulling and detachment from the brush assembly 210. Finally, the hair is absorbed by the suction element 7 of the hair adsorption mechanism within the roller brush cavity of the floor brush body 100, which absorbs the hair as it rolls... The component 200 rolls fine hairs that are repeatedly removed from the brush component 210, thereby improving the cleaning efficiency of the hairs on the roller brush and avoiding the problem of subsequent cleaning difficulties caused by dense entanglement of hairs on the brush component 210 during use. The hair is pulled out of the brush component 210 by the hair grabbing mechanism and then cut. Compared with the common structure and method of cutting the hairs by direct contact between the blades and scrapers, this can reduce the damage to the brush component 210 and ensure its adsorption efficiency of dust and hair on the ground.

[0087] The drive mechanism includes two gears that connect the rotating shaft of the drive device and the rolling assembly 200, and the two gears are meshed together.

[0088] A drive gear extends coaxially from the gear on the drive device, and a driven gear 12 extends coaxially from the metal blade connecting rod 11. The drive gear and the driven gear 12 are driven together by a conveyor belt 13. Of course, the drive mechanism can also adopt a multi-gear set structure to ensure transmission stability; wherein, the drive gear should be correspondingly set on the gear that is an even number of gears away from the gear connecting the rolling assembly 200 (the even number of gears mesh with the gear connecting the rolling assembly 200 one by one), thereby ensuring the design of the metal blade comb 1 and the rolling assembly 200 rotating in opposite directions.

[0089] The gripper assembly 3 includes a hinge base 31 and a clamping block 33 hinged to the hinge base 31 via a hinge shaft 32. A torsion spring is provided on the hinge shaft 32, and the torsion spring elastically preloads the hinge base 31 and the clamping block 33. The torsion spring generates a preload force on the clamping block 33, causing it to rotate toward the hinge base 31. The torsion spring can also be replaced by a tension spring, with its end connected to the hinge base 31 and the clamping block 33, thereby ensuring the clamping force of the clamping block 33 and the guide assembly 4 on the hair.

[0090] The linkage component 5 includes a housing 51 and an electrical component 53 disposed within the housing 51. A touch switch 54 corresponding to the pressing block 52 is disposed on the electrical component 53 and inside the housing 51. The pressing block 52 is elastically slidably disposed at the opening of the housing 51.

[0091] The pressing block 52 has a stepped structure. A retaining ring is provided on the outside of the opening of the box 51. The outer side of the pressing block 52 abuts against the inner side of the retaining ring. A ring-shaped elastic element is provided between the retaining ring, the inner wall of the box 51 and the pressing block 52, thereby ensuring one-dimensional sliding of the pressing block 52 and reducing disturbances in other directions. This makes the pressing of the pressing block 52 by the hair and the linkage of the pressing block 52 to the switch 54 more stable and efficient.

[0092] The gripper assembly 3 has a slide 34 at its bottom, which is slidably connected to the guide groove 221 of the first comb plate 2. A reset elastic element 35 is provided between the slide 34 and the guide groove 221, and the reset elastic element 35 forms an elastic preload force on the slide 34 opposite to the linkage assembly 5. This design makes the sliding of the gripper assembly 3 at the guide assembly 4 and the linkage assembly 5 more flexible, and the switching between the hair gripping state and the release state more convenient and stable.

[0093] An electromagnet 55 electrically associated with the electrical component 53 is provided in the guide groove 221 of the first comb plate 2, and a magnet 36 corresponding to the electromagnet 55 is provided on the slide 34, thereby realizing efficient and stable response of the pressing block 52 and the gripper component 3, and realizing stable hair gripping.

[0094] The aforementioned drive equipment uses an electric motor, a pneumatic cylinder, or a hydraulic cylinder.

[0095] The working principle of the rotating metal blade comb structure of a vacuum cleaner floor brush in this embodiment includes: the roller brush cavity of the floor brush body 100 forms a negative pressure environment through the negative pressure system of the vacuum cleaner host, the drive device drives the gear to rotate, drives the roller assembly 200 to rotate, and through the drive gear, the conveyor belt 13, and the driven gear 12, drives the metal blade connecting rod 11 to rotate in the opposite direction to the rotation direction of the roller assembly 200, so that the two are in full contact.

[0096] Pushing the floor brush body 100 causes the roller assembly 200 to clean the floor and cleaning surface. As the roller assembly 200 rotates, the brush assembly 210 picks up dust and hair from the floor and cleaning surface, and rotates to move them above the brush gripping mechanism. Figure 2 As shown, the rolling assembly 200 rotates clockwise, and the metal blade comb 1 rotates counterclockwise;

[0097] As the roller assembly 200 rotates, the first comb plate 2 combs the brush assembly 210. The hair abuts against the guide assembly 4 and is guided to move to the linkage assembly 5. The hair is pressed on the pressing block 52, causing it to move inward and triggering the switch 54. This causes the electrical component 53 to supply power to the electromagnet 55, forming a magnetic field around the electromagnet and creating a magnetic attraction force on the magnet 36. The magnetic attraction force drives the slide 34 to move along the guide groove 221 toward the electromagnet 55. The magnet 36 and the electromagnet 55 are connected, and the slide 34 is positioned. During this process, the hinge seat 31 moves synchronously with the slide 34, and the clamping block 33 moves along the surface of the guide assembly 4. The elastic preload formed by the torsion spring or tension spring on the clamping block 33 as it rotates toward the guide assembly 4, which, together with the guide assembly 4 and the linkage assembly 5, clamps the hair.

[0098] The metal blade comb 1 rotates to cut the hair. After cutting, the tension formed at the end of the hair is removed, causing the hair to detach from the pressing block 52 with the airflow and the centrifugal force generated by the rotation of the component. The pressing block 52 resets, the touch switch 54 switches to the off state, the electromagnet 55 loses its magnetism, and the reset elastic element 35 drives the gripper assembly 3 to reset, thus completing the hair grabbing and cutting operation.

[0099] After cutting, the fine hairs are either directly discharged from the air outlet of the brush body 100 by the airflow after cutting, or remain on the brush assembly 210 and continue to roll through the roller assembly 200. The suction element 7 of the hair suction mechanism adsorbs the fine hairs on the brush assembly 210, causing them to detach from the brush assembly 210. Then, the fine hairs on the suction element 7 are desorbed again under the action of external airflow and discharged from the air outlet of the brush body 100 for unified collection of hair and dust.

[0100] Example 2:

[0101] Please see Figure 3 ,6 Based on the above embodiment 1, preferably, the first comb plate 2 includes a first base plate 21 mounted on the floor brush body 100 and a first mounting plate 22 spaced on the first base plate 21 and extending toward the roller assembly 200.

[0102] The first clearance groove 23 between the first mounting plates 22 corresponds to the metal blade comb teeth 1;

[0103] The gripper assembly 3, guide assembly 4, and linkage assembly 5 are disposed on the first mounting plate 22.

[0104] The second comb plate 6 includes a second base plate 61 mounted on the floor brush body 100 and a second mounting plate 62 spaced on the second base plate 61 and extending toward the roller assembly 200;

[0105] The second clearance groove 63 between the second mounting plates 62 corresponds to the metal blade comb teeth 1;

[0106] The adsorption element 7 is disposed at the end of the second mounting plate 62.

[0107] By setting the comb structure on the hair grasping mechanism and hair adsorption mechanism, the hair on the brush assembly 210 can be combed, so that the guide assembly 4 captures the hair, the hair and linkage assembly 5 are linked, the gripper assembly 3 grasps the hair more fully, stably and efficiently, and the adsorption component 7 adsorbs the hair more completely; while ensuring hair grasping, the comb structure can also avoid the metal blade comb teeth 1, ensuring no interference between the structures.

[0108] Example 3:

[0109] Please see Figure 4 , 5 Based on the above embodiment 1, preferably, the guide component 4 extends an arc-shaped guide slope 42 toward the linkage component 5, and the guide component 4 forms a limiting block 41 toward the clamping block 33.

[0110] The bottom of the clamping block 33 is provided with a positioning groove 331 corresponding to the limiting block 41.

[0111] The above design allows the guide component 4 to be guided by the arc-shaped guide slope 42 when it comes into contact with the hair, and move to the recess between the arc-shaped guide slope 42 and the box 51 for initial hair positioning. The clamping block 33 moves toward the hair and rotates toward the guide component 4 through the setting of the positioning groove 331. The limiting block 41 engages with the positioning groove 331 to achieve structural locking and complete the stable gripping of the hair. A wedge-shaped surface should be set on the side of the positioning groove 331 facing the linkage component 5 to cooperate with the arc-shaped guide slope 42. After the hair is cut and the pressing block 52 is reset, it is easy for the clamping block 33 to disengage from the guide component 4 to complete the structural reset.

[0112] Example 4:

[0113] Please see Figure 7 Based on the above embodiment 1, preferably, a discharge module 8 is provided inside the second comb plate 6;

[0114] Specifically, the discharge module 8 is electrically connected to a time relay;

[0115] Furthermore, the discharge module 8 penetrates the second comb plate 6 through the conductive medium 81 and docks with the adsorption element 7;

[0116] The discharge module 8 emits positive or negative charged particles to the adsorption element 7 according to a set time interval.

[0117] The working principle of the rotating metal blade comb structure of a vacuum cleaner floor brush in this embodiment includes: the mechanism by which the adsorption element 7 acts on fine hairs is that the discharge module 8 periodically transfers charged particles to the adsorption element 7 through the conductive medium 81, making it charged and thus adsorbing the hairs. During this process, charged particles with opposite charges are alternately transferred to neutralize the charges, making the adsorption element 7 electrically neutral. This design achieves the adsorption of hairs by the adsorption element 7 when it is charged, the desorption of hairs from the brush assembly 210, and the desorption of hairs by airflow in the electrically neutral state. The hairs are then discharged from the air outlet of the floor brush body 100 for unified collection.
