Technical Field

[0001] This utility model relates to the field of air purification equipment technology, and in particular to an integrated air purification and formaldehyde removal machine. Background Technology

[0002] As people's living standards improve, their requirements for indoor air quality are also increasing. Formaldehyde, as one of the main components of indoor air pollution, poses a serious threat to human health, such as irritating the respiratory tract, causing allergic reactions, and even potentially causing cancer. In response to this, indoor air purifiers mainly need two functions: eliminating dust in the air and eliminating volatile organic compounds such as formaldehyde.

[0003] In existing technologies, activated carbon fiber felt with nano-titanium dioxide is usually used as a composite formaldehyde removal material. Activated carbon fiber felt has a huge specific surface area and can adsorb formaldehyde molecules in the air. After long-term use, the adsorbed formaldehyde molecules will affect the adsorption effect of activated carbon fiber felt, resulting in poor formaldehyde removal effect. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: after long-term use, the adsorbed formaldehyde molecules will affect the adsorption effect of activated carbon fiber felt, resulting in poor formaldehyde removal effect. Therefore, this invention proposes an integrated air purification and formaldehyde removal machine.

[0009] Preferably, a rectangular inlet is provided on the side of the housing, a water collection box is inserted into the rectangular inlet, and a sealing plate is fixedly installed on one side of the water collection box, with the side of the sealing plate in sealing contact with the side of the housing.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-3 An integrated air purification and formaldehyde removal machine includes a housing 1, with an air inlet at the lower end and an air outlet at the upper end. A filter assembly for filtering air is installed inside the housing 1. An mounting plate 2 is installed inside the housing 1, and a fan 3 is installed in the center of the mounting plate 2. The fan 3 can provide sufficient power for the air to flow inside the device, drawing in outside air through the air inlet and then expelling it from the air outlet.

[0016] An installation frame 4 is installed inside the housing 1 by bolt fasteners. The installation frame 4 is filled with activated carbon fiber felt 5 loaded with nano titanium dioxide. Ultraviolet lamps 6 are fixedly installed on both inner walls of the housing 1. Both ultraviolet lamps 6 are located above the activated carbon fiber felt 5. A rectangular box 7 is horizontally slidably installed inside the housing 1 by a moving component. A water-absorbing cotton block 8 is installed inside the rectangular box 7. The upper surface of the water-absorbing cotton block 8 is in contact with the lower surface of the activated carbon fiber felt 5.

[0017] Activated carbon fiber felt 5 is a novel composite formaldehyde removal material. It has a large specific surface area, enabling it to adsorb formaldehyde molecules in the air. When air passes through the felt, formaldehyde molecules are adsorbed onto it. Simultaneously, ultraviolet light emitted by the UV lamp 6 irradiates the felt, causing nano-titanium dioxide to decompose formaldehyde into carbon dioxide and water. The core process is based on photocatalytic oxidation. A movable component allows a rectangular box 7 to move horizontally back and forth within the housing 1. Absorbent cotton blocks 8 inside the rectangular box 7 absorb the generated water, effectively removing formaldehyde molecules adsorbed on the activated carbon fiber felt 5 and significantly improving formaldehyde removal efficiency.

[0018] Reference Figure 5The moving component includes a reciprocating screw 9 horizontally rotatably mounted inside the housing 1, a drive motor 10 fixedly mounted on the outside of the housing 1, a moving block 11 threaded onto the reciprocating screw 9, and a bracket 12 fixedly mounted on the upper end of the moving block 11. One end of the reciprocating screw 9 extends out of the housing 1 and is fixedly connected to the output end of the drive motor 10. The rectangular box 7 is fixedly mounted on the bracket 12. When the drive motor 10 is started, it can drive the reciprocating screw 9 to rotate. Under the action of the reciprocating screw 9, it can drive the moving block 11 to move horizontally back and forth, and then drive the rectangular box 7 to move horizontally back and forth through the bracket 12.

[0019] The movable block 11 has symmetrical limit holes on its side. Limit rods 13 are horizontally slidably inserted into each of the two limit holes. Both limit rods 13 are horizontally fixed inside the housing 1. The limit rods 13 limit the movable block 11. When the reciprocating screw 9 rotates, it can restrict the movable block 11 from rotating with the reciprocating screw 9, ensuring that the movable block 11 can move horizontally stably.

[0020] Reference Figure 4 and Figure 6 The rectangular box 7 has multiple water outlet holes on its side and symmetrical movable holes on its side. A top rod 14 is horizontally slidably installed in each of the two movable holes. A pressure plate 15 is fixedly installed at one end of each of the two top rods 14. The pressure plate 15 is located inside the rectangular box 7. Multiple blocking blocks 16 are fixedly installed on the side of the pressure plate 15. The multiple blocking blocks 16 are respectively inserted into the multiple water outlet holes. A rectangular socket is opened on the side of the housing 1. A water collection box 17 is inserted into the rectangular socket. A sealing plate 18 is fixedly installed on one side of the water collection box 17. The side of the sealing plate 18 is in sealing contact with the side of the housing 1.

[0021] The absorbent cotton block 8 can undergo elastic expansion and contraction deformation. In the initial state, multiple plugs 16 are inserted into multiple water outlets to prevent water from flowing out of the rectangular box 7. The water absorbed by the absorbent cotton block 8 will enter the rectangular box 7. When the rectangular box 7 moves to one side, it moves directly above the water collection box 17. One end of each of the two push rods 14 will simultaneously contact the inner wall of the housing 1, thereby driving the pressure plate 15 to move towards the absorbent cotton block 8, squeezing the absorbent cotton block 8 and squeezing out the water absorbed by it. At the same time, the plugs 16 are removed from the water outlets, and the water in the rectangular box 7 will flow out from the water outlets and into the water collection box 17, which collects the water. The water collection box 17 can also be pulled out from the rectangular inlet to treat the collected water.

[0022] Reference Figure 2The housing 1 has two slotted openings on its side. The filter assembly includes two mounting brackets 19 inserted into the housing 1, two strip plates 20 respectively fixedly mounted on the two mounting brackets 19, and two filter screens 21 respectively mounted on the two mounting brackets 19. The two strip plates 20 are respectively sealed and inserted into the two slots. The activated carbon fiber felt 5 is located between the two filter screens 21. The two filter screens 21 are arranged vertically inside the housing 1. The lower filter screen 21 is the pre-filter layer, which adopts a metal mesh structure and is used to filter larger particles of dust, hair and other impurities in the air to prevent these impurities from entering the subsequent modules and affecting the normal operation of the equipment. The upper filter screen 21 is the high-efficiency filter layer, which adopts a HEPA filter and can filter small particles of air such as PM2.5, pollen and bacteria, further improving the air purification quality.

[0023] In this invention, when air passes through the activated carbon fiber felt 5, formaldehyde molecules in the air are adsorbed onto the activated carbon fiber felt 5. At the same time, ultraviolet light emitted by the ultraviolet lamp 6 irradiates the activated carbon fiber felt 5. Under the irradiation of the ultraviolet lamp 6, nano titanium dioxide decomposes formaldehyde into carbon dioxide and water. The core is based on photocatalytic oxidation reaction. Meanwhile, the moving component can drive the rectangular box 7 to move horizontally back and forth within the shell 1. The water-absorbing cotton block 8 inside the rectangular box 7 can absorb the generated water, which can effectively remove the formaldehyde molecules adsorbed on the activated carbon fiber felt 5, effectively improving the formaldehyde removal effect.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
