Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a high-efficiency filtering device based on a carbon nanotube array. Background Art

[0002] The high-efficiency filter device based on carbon nanotube array is an innovative device that uses the excellent performance of carbon nanotube array to enhance the filtering effect. The carbon nanotube array has an extremely high specific surface area and can effectively adsorb and intercept particles in the air, including tiny particles and bacteria, which enables the high-efficiency filter device based on carbon nanotube array to achieve extremely high filtering efficiency. The carbon nanotube array has good chemical stability and is not easily affected by environmental factors. The pore size of the carbon nanotube array is small and evenly distributed, so that the air encounters less resistance when passing through the filter device, which can ensure good air circulation performance.

[0003] An air purification device disclosed in the patent application with reference publication number CN208525491U includes a shell, an air purification device, a fan and a power module. The shell has an air outlet; the air purification structure is arranged in the shell and adjacent to the air outlet; the fan is arranged in the shell, and an air outlet side of the fan corresponds to the position of the air purification structure; and the power module is electrically connected to the air purification structure and the fan respectively. In this way, the new air purification device uses the air purification structure adjacent to the air outlet of the shell, and the air outlet side of the fan corresponds to the position of the air purification structure to spread the air containing negative ions, thereby purifying the surrounding air and circulating and purifying the air inside.

[0004] As shown in the above-mentioned prior art, the existing air filtering device uses a fan to suck air into the device through the filter, and then uses an induction electrode and a discharge electrode to filter the air and then discharge it. During the long-term use of the device, the filter will accumulate a large amount of dust particles. If it is not manually observed and cleaned in time, it will lead to low air filtration efficiency and even poor filtration effect.

[0005] Therefore, it is necessary to provide a high-efficiency filtering device based on a carbon nanotube array to solve the above technical problems. Utility Model Content

[0036] The utility model provides two technical solutions:

[0039] The mounting shell 4 is fixed to the top of the box body 1;

[0040] The air filter assembly is fixed inside the box 1 and the top is fixed to the mounting shell 4. The air filter assembly is installed from the outside to the inside with a coarse filter 5 for filtering large particles of impurities, a high-efficiency filter 6 made of a carbon nanotube array, an activated carbon layer 7 and an ultraviolet disinfection lamp 8;

[0041] The dust removal component is installed inside the box 1 and is used to clean large particles of dust, hair and other substances adsorbed on the coarse filter 5. The cleaned impurities eventually fall into the dust box 3;

[0042] The air pump 9 is fixed on the mounting shell 4, and the air inlet is connected to the ultraviolet disinfection lamp 8 inside the air filter assembly;

[0043] The placement frame 10 is fixed to the side wall of the installation shell 4 and is communicated with the air outlet of the air pump 9. The fragrance sheet 22 is clamped in the placement frame 10 through a buckle assembly.

[0044] The dust removal assembly includes a slide groove 11 symmetrically opened on the inner wall of the box body 1, and a dust scraper ring 12 is slidably connected to the inner wall of the two slide grooves 11. The inner wall of the dust scraper ring 12 is slidably connected to the outer wall of the coarse filter 5. A screw 13 is rotatably connected under the mounting shell 4, and the lower end of the screw 13 is rotatably connected to the inner wall of the box body 1. The dust scraper ring 12 is threadedly connected to the screw 13, and a motor 14 is fixed inside the mounting shell 4, and the output end of the motor 14 is fixed to the upper end of the screw 13.

[0045] This application sets up a dust removal component so that large particles of dust and hair filtered out by the coarse filter 5 can be removed electrically, without the need to manually disassemble the filter element for cleaning, thus saving manpower and being practical, and preventing large particles of dust from accumulating on the filter screen, resulting in poor air filtration effect.

[0046] Figures 7 and 8 A second embodiment is shown, which mainly differs from the first embodiment in that: the buckle assembly includes a card shell 15 fixed on the fragrance sheet 22, a lifting handle 21 is fixed on the top of the card shell 15, a card slot 16 is provided on the side wall of the card shell 15, a card block 17 is slidably connected to the inner wall of the placement frame 10, the card block 17 is trapezoidal, the card block 17 is snapped onto the inner wall of the card slot 16, a slide bar 18 is fixed to the side of the card block 17 away from the card slot 16, the slide bar 18 is slidably connected to the inner wall of the placement frame 10, a spring 19 is fixed to the side of the card block 17 close to the slide bar 18, the end of the spring 19 away from the card block 17 is fixed to the inner wall of the placement frame 10, a pull block 20 is fixed to the end of the slide bar 18 away from the card block 17, and an anti-slip pattern is provided on the outer wall of the pull block 20.

[0047] This application sets a snap assembly so that the fragrance sheet 22 can be stably snapped into the placement frame 10. When the filtered air is discharged from the air pump 9, the air passes through the placement frame 10 and carries the fragrance of the fragrance sheet 22, making the air smell fresh and improving the user experience.

[0048] Working principle:

[0049] When air filtration is required, the air pump 9 is turned on to suck air into the box body 1 through the air suction hole 2 on the box body 1, and passes through the coarse filter 5 to filter out large particles of dust, hair, etc., and then the air passes through the high-efficiency filter 6 made of a carbon nanotube array to filter out micron particles, smoke particles, etc. in the air that are invisible to the naked eye, and then the air passes through the activated carbon layer 7 to remove odor, and then the ultraviolet disinfection lamp 8 kills bacteria in the air, and then the air is drawn in from the air inlet by the air pump 9, and then passes through the placement frame 10, and then the air carries the odor of the fragrance sheet 22 in the placement frame 10 and is discharged.

[0050] The motor 14 is started regularly to rotate the screw 13, so that the scraper ring 12 cleans the outer wall of the coarse filter 5 from top to bottom along the slide groove 11, and scrapes off the dust and hair accumulated on the coarse filter 5. The scraped dust and hair fall into the dust collecting box 3 through the connecting part between the bottom of the box body 1 and the dust collecting box 3. After the scraper ring 12 is used, the scraper ring 12 stays on the upper end of the coarse filter 5 to prepare for the next use. The garbage in the dust collecting box 3 can be cleaned regularly.

[0051] When the smell of the fragrance sheet 22 dissipates, it needs to be replaced regularly to maintain the fragrance carried in the air when the filter device is used; move the pull block 20 in the direction away from the placement frame 10, the slide bar 18 moves accordingly, the spring 19 is compressed, and the block 17 leaves the slot 16, then the pull handle 21 is lifted to pull out the fragrance sheet 22 to release the pull block 20; align the end of the card shell 15 with the slot 16 of the new fragrance sheet 22 with one side of the card block 17 of the placement frame 10 and put it in, the bottom of the fragrance sheet 22 squeezes the inclined surface of the card block 17 to compress the spring 19, and the card block 17 enters the inner wall of the placement frame 10, until the slot 16 on the side wall of the card shell 15 is aligned with the card block 17, the spring 19 rebounds to clamp the card block 17 into the slot 16, and the fragrance sheet 22 is fixed in the placement frame 10.
