Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a rotary metal blade comb structure of a vacuum cleaner floor brush. Background Art

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

[0003] Existing vacuum cleaners are always troubled by hair entanglement during operation, and there is no effective way to deal with it. When in use, the brush assembly on the roller brush absorbs dust and hair on the ground and the cleaning surface, and the hair will gradually extend and entangle in the brush assembly under the influence of factors such as airflow, making subsequent roller brush cleaning very difficult. Some vacuum cleaners will have hair cutting and brush assembly combing mechanisms to improve the problem of hair entanglement. They generally use cutters and scrapers, but this design cannot effectively and stably capture and grab the hair. The tension at the end of the hair is insufficient, causing the hair to slide on the cutter and scraper, and it is impossible to complete sufficient cutting and combing; common scrapers and cutters directly cut into the brush assembly to cut the hair, which will also damage the brush assembly and affect the roller brush adsorption and cleaning efficiency; due to the complexity of hair entanglement, some of the fine hair after cutting will be embedded in the brush assembly, and cannot be adsorbed, scraped, or guided out of the brush assembly by airflow or combing mechanisms, making subsequent roller brush cleaning more difficult.

[0051] In summary, due to the adoption of the above technical solution, the utility model has the following advantages compared with the prior art:

[0052] Beneficial effects:

[0053] 1. The utility model uses a hair grabbing mechanism to grab the hair on the brush assembly in a linked manner to ensure that the tension at its end is sufficient and stable. Then, the hair cutting mechanism and the roller brush assembly rotate in opposite directions relative to each other, and the metal blade comb teeth cut the hair grabbed by the hair grabbing mechanism, thereby reducing the extension length and complexity of the hair in the brush assembly and the difficulty of pulling the hair and desorption on the brush assembly caused by the hair grabbing mechanism. Then, the adsorption part of the hair adsorption mechanism in the roller brush cavity of the floor brush main body is used to reciprocate and desorb the fine hair rolling with the roller assembly on the brush assembly, thereby improving the cleaning efficiency of the hair on the roller brush and avoiding the problem of subsequent cleaning difficulties caused by dense entanglement of the hair on the brush assembly during use. The hair on the brush assembly is pulled out by the hair grabbing mechanism and then cut. Compared with the common structure and method in which a blade or a scraper directly contacts the brush to cut the hair therein, the damage to the brush assembly can be reduced, and the adsorption efficiency of the dust and hair on the ground can be ensured.

[0054] 2. When in use, as the roller assembly rotates, the first comb plate combs the brush assembly, the hair abuts the guide assembly, and is guided by it to move to the linkage assembly, the hair presses on the pressing block, causing it to move inward and trigger the switch, so that the electrical assembly supplies power to the electromagnet, a magnetic field is formed around the electromagnet, and a magnetic attraction is formed on the magnet, the magnetic attraction drives the slide to move along the guide groove toward the electromagnet, the magnet and the electromagnet are docked, and the slide is positioned; during this period, the hinged seat moves synchronously with the slide, the clamping block moves along the surface of the guide assembly, and the elastic pre-tightening force formed by the torsion spring or the tension spring on the clamping block toward the guide assembly is used to clamp the hair in cooperation with the guide assembly and the linkage assembly; the metal blade comb teeth rotate to comb the hair After cutting, the pulling force formed at the end of the hair is removed, so that the hair is separated from the pressing block by the centrifugal force formed by the airflow and the rotation of the parts, the pressing block is reset, the trigger switch is switched to the off state, the electromagnet loses its magnetism, and the reset elastic part drives the clamping claw assembly to reset, thus completing the operation of grabbing and cutting the hair; the fine and broken hair after cutting is either directly guided out of the air outlet of the floor brush main body by the airflow after cutting, or remains on the brush assembly and continues to roll through the roller assembly, the adsorption part of the hair adsorption mechanism adsorbs the fine and broken hair on the brush assembly to make it separate from the brush assembly, and then the fine and broken hair on the adsorption part is desorbed again under the action of the external airflow, and guided out of the air outlet of the floor brush main body to collect the hair and dust uniformly.

[0055] 3. The mechanism of action of the adsorbent on fine hair is that the discharge module will transfer charged particles to the adsorbent through the conductive medium at regular intervals to make it charged and adsorb the hair. During this period, charged particles with opposite charges are transferred alternately to neutralize the charge, making the adsorbent electrically neutral. This design enables the adsorption of hair in the charged state of the adsorbent, the desorption of hair on the brush assembly, and the desorption of hair under the neutral state under the guidance of airflow. The hair is guided out of the air outlet of the brush body to complete unified collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] Embodiment 1:

[0074] Please refer to Figure 1-7 , the present utility model provides a technical solution: a rotating metal blade comb tooth structure for a vacuum cleaner floor brush, including:

[0075] A hair cutting mechanism, which is disposed inside the floor brush main body 100 and 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;

[0076] Among them, the metal blade teeth 1 are symmetrically distributed along the surface of the metal blade connecting rod 11, and the extending direction of the metal blade teeth 1 is the same as the rotation direction of the metal blade connecting rod 11. This ensures that the metal blade teeth 1 efficiently cut and shred the hair pulled out from the roller assembly 200, so that the subsequent comb structure can scrape off the broken hair, avoiding the problem that the hair is inconvenient to pull out due to the excessive extension of the hair in the brush assembly 210, and cooperating with the internal negative pressure to fully collect the hair, improving the cleanliness of the brush assembly 210 and reducing the cleaning frequency.

[0077] The metal blade connecting rod 11 is associated with the driving mechanism of the roller assembly 200, and the metal blade teeth 1 are driven to rotate in the opposite direction to the roller assembly 200. With this design, the contact frequency between the metal blade teeth 1 and the hair and the cutting force during cutting are increased, the use of driving equipment is reduced, the cost and energy consumption are reduced, and the space occupation is reduced, making the design of the vacuum cleaner floor brush more compact and functional, and facilitating transportation, storage and use.

[0078] The metal blade teeth 1 clean the hair on the brush assembly 210 of the roller assembly 200.

[0079] The hair grasping mechanism is located upstream of the hair cutting mechanism in the rotation direction of the roller assembly 200, and includes a first comb plate 2 and a jaw assembly 3, a guiding assembly 4, and a linkage assembly 5 arranged in sequence along the surface of the first comb plate 2 and facing the roller assembly 200.

[0080] Through this design, the hair can be stably grasped before the metal blade teeth 1 cut the hair, avoiding the problem that the hair slips on the metal blade teeth 1 due to insufficient pulling force at both ends.

[0081] The jaw assembly 3 is slidably arranged on the first comb plate 2. With this design, it is convenient to adjust the position of the jaw assembly 3 at the guiding assembly 4 and the linkage assembly 5 to realize the efficient switching between the clamping state and the releasing state of the comb structure.

[0082] A pressing block 52 is arranged on the linkage assembly 5 facing the guiding assembly 4, and the pressing block 52 is associated with the jaw assembly 3.

[0083] Among them, the guiding assembly 4 is used to pull and guide the hair on the brush assembly 210 when the brush assembly 210 passes through the first comb plate 2, so that the hair moves to the linkage assembly 5. The hair presses the pressing block 52, thereby linking the jaw assembly 3 to cooperate with the guiding assembly 4 and the linkage assembly 5 to clamp the hair, ensuring the stable pulling force at the end of the hair and making the cutting of the metal blade teeth 1 more sufficient.

[0084] In order to improve the desorption efficiency of fine hair cut by the metal blade comb teeth 1 on the brush assembly 210, a component for hair adsorption is also provided in the floor brush of the vacuum cleaner, which is specifically designed as: a hair adsorption mechanism, which is arranged in the floor brush body 100 and extends radially along the roller assembly 200, including a second comb tooth plate 6 and an adsorption member 7 arranged on the second comb tooth plate 6.

[0085] Among them, the hair adsorption mechanism can be arranged in multiple directions 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 the hair on the brush assembly 210, improve the cleanliness of the floor brush body 100, and improve the user's convenience and experience.

[0086] The above-mentioned hair grabbing mechanism and hair cutting mechanism are both arranged above the air outlet of the roller brush cavity of the floor brush body 100, so that the hair detached from the brush assembly 210 here is guided by gravity and the airflow at the air outlet, and is guided out from the air outlet for collection, thereby preventing the broken hair from falling back onto the ground or the inner wall of the roller brush cavity of the floor brush body 100 and causing problems such as dirt collection, low cleaning efficiency, and low cleanliness of the vacuum cleaner floor brush due to contamination, thereby improving the use efficiency.

[0087] The utility model uses the hair grabbing mechanism to grab the hair on the brush assembly 210 in a linked manner to ensure that the tension at its end is sufficient and stable. Then the hair cutting mechanism and the roller brush assembly 200 rotate in opposite directions relative to each other, and the metal blade comb teeth 1 cut the hair grabbed by the hair grabbing mechanism, thereby reducing the extension length and complexity of the hair in the brush assembly 210 and the difficulty of pulling the hair and desorption on the brush assembly 210 caused by the hair grabbing mechanism. Then, the hair adsorption mechanism in the roller brush cavity of the floor brush body 100 is used to absorb the hair along with the roller brush. The fine hair rolled by the body component 200 is subjected to a reciprocating desorption process on the brush component 210, thereby improving the cleaning efficiency of the hair on the roller brush and avoiding the problem of subsequent cleaning difficulties caused by the dense entanglement of the hair on the brush component 210 during use. The hair on the brush component 210 is pulled out by the hair grabbing mechanism and then cut. Compared with the common structure and method of directly contacting the brush with a blade or scraper to cut the hair therein, the damage to the brush component 210 can be reduced, thereby ensuring its efficiency in adsorbing dust and hair on the ground.

[0088] The driving mechanism includes two gears connected to the rotating shaft of the driving device and the roller assembly 200, and the two gears are meshed and connected;

[0089] A driving gear coaxially extends on the gear of the driving device, and a driven gear 12 coaxially extends on the metal blade connecting rod 11. The driving gear and the driven gear 12 are associated and driven by a conveyor belt 13. Of course, the driving mechanism can also adopt a multi-gear set structure to ensure the transmission stability. Among them, the driving gear should be correspondingly arranged on the gear that is separated from the gear of the connecting roller assembly 200 by an even number of gears (the even number of gears are meshed and connected with the gear of the connecting roller assembly 200 one by one), thereby ensuring the design of the reverse rotation drive of the metal blade comb teeth 1 and the roller assembly 200.

[0090] The clamping jaw assembly 3 includes a hinge seat 31 and a clamping block 33 hinged to the hinge seat 31 through a hinge shaft 32. A torsion spring is arranged on the hinge shaft 32, and the torsion spring is elastically pre-tightened to connect the hinge seat 31 and the clamping block 33. Among them, the torsion spring forms a pre-tightening force for the clamping block 33 to rotate towards the hinge seat 31. The torsion spring can also be replaced by a tension spring, and the end of the tension spring is connected to the hinge seat 31 and the clamping block 33, thereby ensuring the clamping force of the clamping block 33 and the guiding assembly 4 on the hair.

[0091] The linkage assembly 5 includes a box body 51 and an electrical component 53 arranged in the box body 51. A touch switch 54 corresponding to the pressing block 52 is arranged on the electrical component 53 and inside the box body 51. The pressing block 52 is elastically slidably arranged at the opening of the box body 51.

[0092] Among them, the pressing block 52 has a stepped structure, a retaining ring is arranged outside the opening of the box body 51, the outside of the pressing block 52 abuts against the inside of the retaining ring, and an annular elastic member is arranged between the retaining ring, the inner wall of the box body 51 and the pressing block 52, thereby ensuring the one-dimensional sliding of the pressing block 52, reducing the disturbance in other directions, and making the pressing of the hair on the pressing block 52 and the linkage of the pressing block 52 to the touch switch 54 more stable and efficient.

[0093] A sliding seat 34 is arranged at the bottom of the clamping jaw assembly 3. The sliding seat 34 is slidably connected in the guide groove 221 of the first comb plate 2. A return elastic member 35 is arranged between the sliding seat 34 and the guide groove 221, and the return elastic member 35 forms an elastic pre-tightening force on the sliding seat 34 away from the linkage assembly 5. The above design makes the sliding of the clamping jaw assembly 3 at the guiding assembly 4 and the linkage assembly 5 more flexible, and the switching between the hair grasping state and the releasing state more convenient and stable.

[0094] An electromagnet 55 electrically associated with the electrical component 53 is arranged in the guide groove 221 of the first comb plate 2, and a magnet 36 corresponding to the electromagnet 55 is arranged on the sliding seat 34, thereby realizing the efficient and stable response between the pressing block 52 and the clamping jaw assembly 3 and realizing the stable grasping of the hair.

[0095] The above driving device adopts a motor, a cylinder or a hydraulic cylinder.

[0096] The working principle of the rotating metal blade comb structure of the floor brush of a vacuum cleaner of the present 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 driving device drives the gear to rotate, drives the roller assembly 200 to rotate, and drives the metal blade connecting rod 11 to rotate in the opposite direction to the roller assembly 200 through the driving gear, the conveyor belt 13, and the driven gear 12, so that the two are fully in contact;

[0097] The floor brush body 100 is pushed, so that the roller assembly 200 cleans the floor and the cleaning surface, and the brush assembly 210 absorbs the dust and hair on the floor and the cleaning surface as the roller assembly 200 rotates, and rotates to drive it to move above the brush grabbing mechanism, such as Figure 2 As shown, the roller assembly 200 rotates clockwise, and the metal blade comb teeth 1 rotates counterclockwise;

[0098] 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 by it to move to the linkage assembly 5, the hair presses on the pressing block 52, causing it to move inward and link the trigger switch 54, so that the electrical assembly 53 supplies power to the electromagnet 55, a magnetic field is formed around the electromagnet, and a magnetic attraction force is formed 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 period, the articulated seat 31 moves synchronously with the slide 34, the clamping block 33 moves along the surface of the guide assembly 4, and the elastic pre-tightening force formed by the torsion spring or the tension spring on the clamping block 33 to rotate toward the guide assembly 4, cooperates with the guide assembly 4 and the linkage assembly 5 to clamp the hair;

[0099] The metal blade comb teeth 1 rotate to cut the hair. After cutting, the pulling force formed by the hair ends is removed, so that the hair is separated from the pressing block 52 by the airflow and the centrifugal effect formed by the rotation of the parts. The pressing block 52 is reset, the trigger switch 54 is switched to the off state, the electromagnet 55 loses its magnetism, and the reset elastic member 35 drives the clamping claw assembly 3 to reset, thus completing the operation of grabbing and cutting the hair.

[0100] After being cut, the fine and broken hair is either driven by the airflow to be directly guided out of the air outlet of the floor brush body 100 after being cut, or remains on the brush assembly 210 and continues to roll through the roller assembly 200. The adsorption component 7 of the hair adsorption mechanism adsorbs the fine and broken hair on the brush assembly 210 to separate it from the brush assembly 210. After that, the fine and broken hair on the adsorption component 7 is desorbed again under the action of the external airflow and guided out of the air outlet of the floor brush body 100 to collect the hair and dust in a unified manner.

[0101] Embodiment 2:

[0102] See also Figure 3 ,6 , on the basis of the first embodiment above, preferably, the first comb plate 2 includes a first substrate 21 assembled on the floor brush body 100, and first mounting plates 22 spaced apart on the first substrate 21 and extending toward the roller assembly 200;

[0103] The first avoidance tooth grooves 23 between the first mounting plates 22 correspond to the metal blade teeth 1;

[0104] The jaw assembly 3, the guiding assembly 4, and the linkage assembly 5 are arranged on the first mounting plates 22.

[0105] The second comb plate 6 includes a second substrate 61 assembled on the floor brush body 100, and second mounting plates 62 spaced apart on the second substrate 61 and extending toward the roller assembly 200;

[0106] The second avoidance tooth grooves 63 between the second mounting plates 62 correspond to the metal blade teeth 1;

[0107] The adsorbent 7 is arranged at the end of the second mounting plate 62.

[0108] By arranging the above-mentioned comb structures on the hair grasping mechanism and the hair adsorption mechanism, the hair on the brush assembly 210 can be combed, so that the guiding assembly 4 captures the hair, the hair is linked with the linkage assembly 5, the jaw assembly 3 grasps the hair more fully, stably and efficiently, and the adsorbent 7 adsorbs the hair more completely; while ensuring the hair grasping, the comb structure can also avoid the metal blade teeth 1 to ensure that there is no interference in the structure.
