Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum cleaners, and particularly relates to a cyclone cone structure of a vacuum cleaner capable of cutting off hair. Background Art

[0002] Vacuum cleaners, as powerful assistants for modern household cleaning, are deeply loved by numerous families for their high efficiency and convenience. Driven by a powerful motor, they use the suction principle to capture all kinds of tiny particles such as dust, hair, and debris on the ground, furniture surfaces, and hard-to-reach gaps, quickly restoring the home environment to freshness and cleanliness.

[0003] In terms of design, vacuum cleaners pursue humanization and versatility. Handheld vacuum cleaners are lightweight and flexible, facilitating the cleaning of high or narrow spaces such as sofa gaps and the tops of bookshelves; upright vacuum cleaners are equipped with various suction heads, easily meeting the cleaning needs of different material surfaces such as carpets, hardwood floors, and tiles. At the same time, many high-end models have incorporated intelligent sensing technology to automatically adjust the suction power, which is both energy-saving and efficient.

[0004] In addition, the filtration system of vacuum cleaners is also crucial for their performance. High-quality HEPA filters can effectively filter fine dust, allergens, and even some bacteria, ensuring that the discharged air is purer and protecting the respiratory health of family members. Some products are also equipped with a one-key dust emptying design, eliminating the need to directly contact the dust when cleaning the dust box, which is both hygienic and convenient.

[0005] Currently, when vacuum cleaners are cleaning, some hair will wind around the roller brush, affecting the cleaning efficiency of the roller brush. At the same time, some long hair enters the dust cup along the air flow without being cut, easily clogging the filter or air duct of the dust cup, resulting in a decrease in the suction power of the vacuum cleaner, and even damaging the device. Moreover, the presence of long hair increases the cleaning difficulty of the dust cup, requiring more time and effort to thoroughly remove.

[0006] At present, the Chinese patent vacuum cleaner for hair cleaning (CN202310087297.9) includes a vacuum cleaner main body and a hair collection expansion head. A first dust suction channel is provided inside the vacuum cleaner main body, and a first motor is installed in the first dust suction channel. The hair collection expansion head is detachably connected to the front end of the vacuum cleaner main body. The hair collection expansion head includes a housing and a brush disk. An intermediate seat is fixed inside the housing. The brush disk is located below the intermediate seat and is rotatably connected to the intermediate seat. A driver is provided inside the housing. A suction port is provided on the brush disk. A second dust suction channel is provided inside the intermediate seat. The second dust suction channel is located outside the rotational connection part of the intermediate seat for connecting to the brush disk. The suction port is communicated with the second dust suction channel and is used as an inlet. A third dust suction channel communicated with the first dust suction channel is provided inside the housing. The inlet of the third dust suction channel is provided on the side of the intermediate seat and is communicated with the second dust suction channel. A brush bundle is provided at the bottom of the brush disk, and a brush comb is fixed on the housing. The advantages of the present utility model are that the brush disk is rotatably connected to the intermediate seat. A second dust suction channel is provided inside the intermediate seat. The second dust suction channel is located outside the rotational connection part of the intermediate seat for connecting to the brush disk. A third dust suction channel communicated with the first dust suction channel is provided inside the housing. The inlet of the third dust suction channel is provided on the side of the intermediate seat and is communicated with the second dust suction channel. By setting the rotational connection part at the center of the intermediate seat and the second dust suction channel outside the rotational connection part, the third dust suction channel can be directly connected to the side of the second dust suction channel without lengthening the second dust suction channel, thereby making the hair collection expansion head flatter and the structure more compact; when the brush disk rotates and brushes away the hair on the bedsheet and sofa, the brush comb can scrape off the hair on the brush bundle and guide it to the suction port, so that the suction port sucks the hair into the collection expansion head, facilitating the cleaning of the hair on the brush bundle.

[0007] A Chinese patent for a vacuum cleaner roller brush hair removal structure (CN202211645715.3) includes: a floor brush housing, a roller brush body, fixed comb teeth, a fixed comb tooth blade, shearing comb teeth and a shearing comb tooth blade. The fixed comb teeth are arranged on one side of the roller brush body. The end of the first comb tooth portion on the fixed comb teeth is interference fit with the cleaning member. The fixed comb tooth blade is fixedly mounted on the fixed comb teeth. The shearing comb teeth are correspondingly arranged above the fixed comb teeth. The driving device is used to drive the shearing comb teeth to reciprocate along the axis direction of the roller brush body. The length of the second comb tooth portion on the shearing comb teeth is less than the length of the first comb tooth portion. The shearing comb tooth blade is fixedly mounted at the bottom of the shearing comb teeth, and the shearing comb tooth blade contacts the fixed comb tooth blade. Compared with the prior art, the utility model effectively removes the hair rolled up on the roller brush, prevents the hair from being entangled on the roller brush, and ensures the use effect of the vacuum cleaner. When the floor brush is used, the roller brush body rotates to clean the ground, and the first comb tooth portion of the fixed comb teeth is interference fit with the cleaning member of the roller brush body. The hair on the roller brush body is introduced into the gap between the first comb teeth as the roller brush body rotates. At the same time, the shearing comb teeth drive the shearing comb teeth blade to reciprocate along the axis direction of the roller brush body. The fixed comb teeth blade cooperates with the shearing comb teeth blade to shear the hair introduced into the fixed comb teeth. The broken hair will not be entangled on the surface of the roller brush body, and will be sucked into the air intake of the floor brush, effectively removing the rolled hair on the roller brush, preventing the hair from being entangled on the roller brush, and ensuring the use effect of the vacuum cleaner. In the utility model, the angle of the teeth on the fixed comb teeth is inclined at a certain angle to the center line perpendicular to the axis of the roller brush body, and the second comb teeth are similar, so that after the hair is introduced into the inclined gap of the fixed comb teeth, it is not easy to separate from the fixed comb teeth, which is convenient for shearing.

[0008] Chinese Patent: A vacuum cleaner floor brush for preventing hair entanglement (CN202310814532.8). The vacuum cleaner floor brush for preventing hair entanglement includes: two mounting brackets fixedly connected to the positions on both sides of the bottom of the floor brush. A gear is arranged on the inner wall of the mounting bracket through a rotating shaft. A cleaning cylinder is arranged outside the rotating shaft. A protective cover is fixedly connected to the opposite sides of the mounting bracket. Cleaning heads are fixedly connected to the bottoms of the protective covers. Connection ports are fixedly connected to the outsides of the protective covers. One end of each connection port is fixedly connected to a connecting pipe; a mounting box is fixedly connected to the middle position on the front of the floor brush. The vacuum cleaner floor brush for preventing hair entanglement provided by the present utility model can clean the connection or corner between the wall and the ground that cannot be cleaned by the floor brush through the extended cleaning cylinder, and can avoid the cleaning dead angle caused by the distance between the floor brush and the wall, which requires manual cleaning, thereby reducing the workload of users and increasing the user experience. When using the household vacuum cleaner floor brush for preventing hair entanglement, first start the motor to drive two worm wheels to rotate through the first worm, and then drive the rotating shaft rotating groove through the belt pulleys on the two worm wheels through the belt, so as to drive the two rotating brushes to clean the ground. While the two worm wheels are rotating, two rotating rods will be driven to rotate inside the two rotating boxes through the two second worms respectively. The other ends of the two rotating rods drive the gears on the rotating shaft to rotate inside the mounting bracket through the gears. The two gears are meshed and connected to rotate synchronously to drive the rotating shaft. During the rotation of the rotating shaft, the cleaning cylinder will be driven to rotate. The cleaning personnel only need to bring the vacuum cleaner floor brush for preventing hair entanglement close to the connection between the wall and the ground, so that the cleaning cylinder can clean the places that the floor brush cannot clean. At the same time, the sundries cleaned out will be sucked into the inside of the connecting pipe through the connection port on the protective cover, and then the sundries or dust will be sucked into the inside of the vacuum cleaner through the three-way head. At the same time, in order to prevent the outside of the cleaning cylinder from being entangled with hair, a cleaning head is installed on the protective cover to clean the hair entangled on the cleaning cylinder. The device can clean the connection or corner between the wall and the ground that cannot be cleaned by the floor brush through the extended cleaning cylinder, and can avoid the cleaning dead angle caused by the distance between the floor brush and the wall, which requires manual cleaning, thereby reducing the workload of users and increasing the user experience.

[0009] Chinese Patent: A Vacuum Cleaner Floor Brush for Preventing Hair Tangling (CN202310861931.X), comprising a base, a top cover and an air duct. In this utility model, the front scraping strip and its arc surface are used to desorb dust and hair from the ground and continuously guide them to the annular brush body in batches, avoiding their accumulation, reducing the collection load of the annular brush body, ensuring the collection rate of dust and hair. The motor and multi-stage gear drive drive the brush on the annular brush body to rotate closely against the ground, loosen and adsorb the dust and hair on the ground, and under the action of centrifugal force, throw them to the center of the annular brush body. In the vacuum negative pressure environment inside the floor brush, they can be collected. The brush is inclined, making the implementation and effect of this operation more obvious. The side brush gears rotate in different directions according to the differences between the left and right ends of the rotating gear, ensuring that the side brush gears on both sides of the rotating gear can better sweep the hair and dust in front of the front scraping strip, so that the side brush can fully cover and clean the cleaning dead corners of a general floor brush. The front scraping strip and its arc surface are used to desorb dust and hair from the ground and continuously guide them to the annular brush body in batches, avoiding their accumulation, reducing the collection load of the annular brush body, ensuring the collection rate of dust and hair. The motor and multi-stage gear drive drive the brush on the annular brush body to rotate closely against the ground, loosen and adsorb the dust and hair on the ground (especially for dust and hair with a certain moisture content and sticking to each other), and under the action of centrifugal force, throw them to the center of the annular brush body. In the vacuum negative pressure environment inside the floor brush, they can be collected. The brush is inclined, making the implementation and effect of this operation more obvious. The rear scraping strip can block the hair and dust, preventing them from being thrown out of the adsorption range of the annular brush body under the rotation and cleaning of the brush. The side brush gears have differences in the number of gear transmission stages and rotation directions according to the differences between the left and right ends of the rotating gear, ensuring that the side brush gears on both sides of the rotating gear can better sweep the hair and dust in front of the front scraping strip, so that the side brush can fully cover and clean the cleaning dead corners of a general floor brush, avoiding the omission of dust and hair. This vacuum cleaner floor brush can effectively solve the problem that when a roller-type floor brush works, the roller adsorbs dust and hair, but it is difficult to desorb them because they are compacted and wound on the surface of the roller. Moreover, the above-mentioned dust and hair collection method of this utility model can effectively avoid the situation of the floor brush components being stuck due to hair tangling on the floor brush, and compared with the roller-type floor brush, it does not need to be frequently replaced and cleaned, and has a high user experience.

[0010] At present, most vacuum cleaners use blades or improve the air suction channel to cut a part of the hair or smooth and suck the hair in. However, it cannot completely change the situation that long hair enters the dust cup, easily clogs the filter screen or air duct of the dust cup, resulting in a decrease in the suction of the vacuum cleaner, and even damage to the equipment. Moreover, the presence of long hair increases the cleaning difficulty of the dust cup and requires more time and energy to thoroughly remove. Summary of the Utility Model

[0011] The object of the present utility model is to provide a cyclone cone structure for a vacuum cleaner capable of cutting hair, which is proposed to solve the current situation that most vacuum cleaners adopt blades or improve the air suction channel to cut a part of the hair or smooth the hair and suck it in, but it cannot completely prevent long hair from entering the dust cup, easily blocking the filter screen or air duct of the dust cup, resulting in a decrease in the suction of the vacuum cleaner and even damage to the equipment, and the presence of long hair increases the cleaning difficulty of the dust cup and requires more time and energy to completely remove it.
