Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an air purification device. Background Art

[0002] People spend a considerable part of their time indoors, so the quality of indoor air directly affects people's health. Indoor air pollutants affect indoor air quality. Indoor air pollutants can be roughly divided into two categories: gaseous pollutants and particulate pollutants, such as formaldehyde released by buildings, furniture, and decorations, and bacteria in the air.

[0003] The patent with application number CN208458142U proposes an "air purification device" and uses it as a comparative document. Under the irradiation of ultraviolet light emitted by a first ultraviolet lamp, the oxygen in the air can be converted into ozone. Ozone reacts with formaldehyde molecules in the air to generate harmless carbon dioxide and water, which purifies the air. At the same time, ozone can also kill harmful microorganisms such as bacteria and viruses in the air. Excess ozone can decompose ozone molecules under the irradiation of ultraviolet light emitted by a second ultraviolet lamp, and the ozone molecules are reduced to oxygen and discharged.

[0004] The disadvantage of the comparison document is that two ultraviolet lamps are mainly used to purify bacteria and viruses in the air, but the air may contain fine particle impurities such as dust, and the two ultraviolet lamps cannot filter the dust in the air. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of its embodiments based on the overall structure of the present utility model.

[0021] An air purification device comprises: a shell 7, wherein the shell 7 comprises an air inlet 1, an air outlet 2, a first ultraviolet lamp 3, a second ultraviolet lamp 4, an ozone sensor 5, and a formaldehyde sensor 6. A filter area 8 is arranged inside the shell 7, a hollow cylinder 9 is fixedly arranged inside the top of the shell 7, and the bottom of the hollow cylinder 9 is located inside the filter area 8, a filter screen 10 is fixedly arranged on the inner wall of the filter area 8, and the filter screen 10 is a HEPA filter screen and has elasticity, a horizontal plate 11 for collecting dust is fixedly arranged at the bottom of the filter area 8, a knocking rod 12 is vertically slidably connected to the inner wall of the filter area 8, a vertical rod 13 is fixedly arranged at the center of the bottom of the filter screen 10, and the bottom of the vertical rod 13 is fixedly connected to the knocking rod 12.

[0022] Furthermore, a limiting opening 14 is provided at the top of the hollow cylinder 9 , a circular opening 15 is provided at the bottom of the hollow cylinder 9 , two sliding blocks 16 are vertically slidably connected to the inner wall of the hollow cylinder 9 , and a placement plate 17 is fixedly provided on the inner side of the two sliding blocks 16 .

[0023] Furthermore, the front side of the placement plate 17 is rotatably connected to two clamping rods 18, a spring 19 is fixedly provided on the front side of the placement plate 17, a vacuum cleaner 20 is fixedly provided on the outer wall of the shell 7, and the suction nozzle of the vacuum cleaner 20 is located between the filter screen 10 and the horizontal plate 11, and there are two springs 19, and one spring 19 is fixedly connected to one clamping rod 18.

[0024] Next, a knocking block 21 is vertically slidably connected inside the circular mouth 15. The highest point or the lowest point of the knocking block 21 is always located inside the circular mouth 15 regardless of whether it is raised or lowered, so as to prevent the knocking block 21 from leaving the hollow tube 9. A rod 22 is fixedly provided on the top of the placement plate 17, and the rod 22 passes through the limit opening 14.

[0025] Working principle: When the air purification device of the utility model is used, indoor air enters the shell 7 from the air inlet 1 through the air intake fan, the formaldehyde sensor 6 detects the formaldehyde content in the incoming air, and transmits the detected formaldehyde concentration data to the main control board, and the main control board controls the luminous power of the first ultraviolet lamp 3 according to the data, and the indoor air entering the shell 7 can convert oxygen in the air into ozone under the irradiation of the ultraviolet light emitted by the first ultraviolet lamp 3, and the ozone reacts with the formaldehyde molecules in the air to generate harmless carbon dioxide and water, which plays a role in purifying the air. At the same time, ozone can also kill harmful microorganisms such as bacteria and viruses in the air; the excess ozone is irradiated by the ultraviolet light emitted by the second ultraviolet lamp 4, and the ozone molecules are reduced to oxygen, and then the sterilized air passes through the filter area 8, and the filter 10 filters the dust and other particulate impurities in the air, and then the air that has been sterilized and the particulate impurities are filtered out is discharged through the air outlet 2,

[0026] After the filter 10 has been used for a period of time, it needs to be cleaned regularly as follows: after the filter 10 filters out dust and other impurities, the filtered matter will remain on the filter 10. At this time, the rod 22 is pressed to drive the two sliding blocks 16 to descend vertically and then the placement plate 17 descends. When the placement plate 17 descends, the bottom of the clamping rod 18 will contact and pass through the cap head on the top of the knocking block 21. At this time, the two clamping rods 18 can clamp the knocking block 21, and then pull the rod 22 to raise it. Then the tops of the two clamping rods 18 will enter the limit opening 14. As the clamping rod 18 rises and under the action of the limit opening 14, the two clamping rods 18 rotate in the opposite direction to knock the knocking block 21 is released, and then the knocking block 21 drops vertically in the circular mouth 15 and falls to the top of the filter 10. The knocking block 21 always moves in the circular mouth 15. Since the filter 10 is elastic, when the knocking block 21 falls to the top of the filter 10, the filter 10 will shake up and down to shake out the dust, which is beneficial to cleaning the filter 10. The shaken dust falls to the top of the horizontal plate 11. At the same time, the vacuum cleaner 20 is started. When the filter 10 elastically drops, the knocking rod 12 is driven to drop through the vertical rod 13, and then the knocking rod 12 knocks on the top of the placement plate 17 to lift the dust so that it is easy to be sucked in by the vacuum cleaner 20 to complete the collection of the dust.

[0027] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
