[0036] The present invention will be further described below by way of examples, but the present invention is not limited to the scope of the described examples.

[0037] As Figure 1-10 shown, an air purifier that humidifies by means of nano formaldehyde removal includes a body 1. A front panel 101 is provided on the front of the body 1. The front panel 101 is used to install an air inlet 2 and an air outlet 3. Side panels 102 are installed on both sides of the body 1 by screws. By using screws for installation, the side panels 102 can be disassembled and opened, facilitating the maintenance of the internal components of the body 1 from the side.

[0038] The back position of the body 1 is used to install the control box, which provides electrical control for the whole machine. The specific control can adopt a single-chip microcomputer controller. At the same time, a control panel is set on the control box for manual operation.

[0039] As Figure 10 shown, grilles or mesh screens are installed at the positions of the air inlet 2 and the air outlet 3, which play a role in blocking dust from entering. An intake fan 201 is installed inside the air inlet 2 to drive the air flow and make the external air enter the air inlet 2; while an exhaust fan 301 is installed inside the air outlet 3 to assist in exhausting, facilitating the discharge of the purified air.

[0040] It also includes: an inner box body 4, and the inner box body 4 is installed inside the body 1. Specifically, the outer wall of the inner box body 4 can be fixedly connected to the front and back inner walls of the body 1 through connecting pieces. For example, through angle steels, the angle steels are welded to the outer wall of the inner box body 4, and the angle steels are installed on the wall of the body 1 through screws; an air intake cavity communicating with the air inlet 2 is formed between the top surface of the inner box body 4 and the inner shell wall of the body 1. A sealing ring 401 is added to the top edge of the inner box body 4. The sealing ring 401 is made of rubber or silica gel to fill the gap between the top edge of the inner box body 4 and the inner walls around the body 1 to form a seal.

[0041] As Figure 2-3 shown, a nano formaldehyde removal component 5, the number of the nano formaldehyde removal components 5 is several, and several nano formaldehyde removal components 5 are distributed in a rectangular array in the inner box body 4. The air inlet end of the nano formaldehyde removal component 5 is communicated with the air intake cavity; several nano formaldehyde removal components 5 are adopted to shunt the air entering the air intake cavity. The air to be purified externally enters the air intake cavity and is shunted into several nano formaldehyde removal components 5, dispersing the air, increasing the purification contact surface, and removing formaldehyde.

[0042] As Figure 3 shown, a condensation component 9, a three-way pipe 8 is installed between the air inlet end of the condensation component 9 and the air outlet end of the nano formaldehyde removal component 5; the air inlet end of the condensation component 9 is the lower end of the vertical pipe 901, and the air outlet end of the nano formaldehyde removal component 5 is the lower end of the decomposition coil pipe 502. The two are connected through the three-way pipe 8. After the air decomposes and removes formaldehyde, the formaldehyde is decomposed into water and carbon dioxide, and at the same time, a certain amount of heat is generated, increasing the air temperature. The air enters the condensation component 9 through the three-way pipe 8 for condensation treatment, liquefying the water in it and flowing along the vertical pipe 901 into the three-way pipe 8.

[0043] A humidifying mechanism, the humidifying mechanism is located below the three-way pipe 8. The humidifying mechanism has a water storage part. The lower port of the three-way pipe 8 is connected to the water storage part. The condensed water flows downward through the three-way pipe 8 into the water storage part and is recycled when air humidification is not required, avoiding waste.

[0044] The air guiding square pipe 7, one port of the air guiding square pipe 7 is fixedly connected to the front surface of the inner box body 4, and the air guiding square pipe 7 is communicated with the inner box body 4. The other end of the air guiding square pipe 7 is communicated with the air outlet 3. After the nano formaldehyde removal component 5 removes formaldehyde in the air, it is directly discharged into the inner box body 4 through the condensation component 9, and is guided by the air guiding square pipe 7 to communicate the inner box body 4 with the air outlet 3. The air outlet 3 discharges the air in the inner box body 4, and discharges the purified air outside the machine body 1.

[0045] Furthermore, a formaldehyde sensor 701 and a humidity sensor 702 are arranged inside the connection position of the air guiding square pipe 7 and the air outlet 3. When the whole machine is running, real-time sensing is carried out to provide a feedback signal for the above control box. When it is judged that the formaldehyde concentration exceeds the preset value therein, it is judged that the formaldehyde concentration is high. At this time, it is necessary to further increase the formaldehyde degradation rate, and heat is carried out through the heating wire 5025 arranged therein to increase the formaldehyde degradation rate by heating and raising the temperature; when it is judged that the humidity exceeds the preset value, humidification is not carried out. When it is lower than the preset value, it is judged that the air is dry, and humidification is carried out through the humidification mechanism.

[0046] As Figure 3-4 shown, the nano formaldehyde removal component 5 includes an inlet cover 501 and a decomposition coil pipe 502. The decomposition coil pipe 502 is spiral, and the upper end of the decomposition coil pipe 502 is connected to the bottom end of the air inlet cover. The upper end of the air inlet cover is fixedly and fittingly connected to the hole body opened at the top of the inner box body 4. The decomposition coil pipe 502 includes an outer pipe body 5021, a nano catalytic layer 5022, an ultraviolet lamp strip 5023, a welding layer 5026 and nano catalytic sheets 5024; the ultraviolet lamp strip 5023 is arranged along the length direction inside the outer pipe body 5021, the nano catalytic layer 5022 is laid on the inner wall of the outer pipe body 5021, and a plurality of nano catalytic sheets 5024 are connected along the length direction around the ultraviolet lamp strip 5023 through the welding layer 5026. One side of the nano catalytic sheet 5024 away from the ultraviolet lamp strip 5023 is connected to the nano catalytic layer 5022 through the welding layer 5026.

[0047] The above welding layer 5026 is formed by welding. When welding, only the welding and fixing at the upper and lower ends of the decomposition coil pipe 502 are required.

[0048] The air intake fan 201 at the air inlet 2 position supplies air into the body 1. The air enters the air intake cavity, then enters the decomposition coil 502 through the air inlet cover 501, and circulates along the decomposition coil 502. During the circulation process, it is illuminated by the ultraviolet light strip 5023. At the same time, the incoming air comes into contact with the nano-catalytic layer 5022 and the nano-catalytic sheet 5024 to achieve formaldehyde decomposition. The spiral shape design of the decomposition coil 502 improves its circulation path. Further, the distribution design of the nano-catalytic layer 5022 and the nano-catalytic sheet 5024 as shown in Figure 4 increases the contact surface to ensure the decomposition of formaldehyde.

[0049] Furthermore, the ultraviolet light strip 5023 can be used for irradiation to sterilize the air and reduce the content of bacteria and germs in the air.

[0050] The nano-catalytic sheet 5024 and the nano-catalytic layer 5022 are both made of nano-material titanium dioxide. Under the illumination of the ultraviolet light strip 5023, the titanium dioxide can decompose formaldehyde.

[0051] like Figure 4 As shown, the nanocatalytic sheet 5024 has multiple pores along its length, each of which is filled with a heating wire 5025. By adding the heating wire 5025, if the formaldehyde concentration in the air is determined to be high, the heating wire 5025 provides heat, which is then conducted through the nanocatalytic sheet 5024, facilitating heat diffusion into the decomposition coil 502, thereby improving the formaldehyde degradation rate.

[0052] A temperature sensor is provided at one end of the tee pipe 8 close to the decomposition coil 502, and the sensing signal is transmitted to the control box in real time for judging the temperature of the exhaust gas from the decomposition coil 502 and providing temperature control for heating the heating wire 5025. The heating wire 5025 can be a carbon fiber heating wire 5025.

[0053] like Figure 3 、 Figure 5 as well as Figure 9As shown in the figure, the condensation assembly 9 includes a vertical pipe 901, an outer sleeve pipe 902, a return pipe 903, and a water inlet pipe 904. The lower port of the vertical pipe 901 is fixedly communicated with one side port of the tee pipe 8, and the other side port of the tee pipe 8 is fixedly communicated with the lower port of the decomposition coil pipe 502. The outer sleeve pipe 902 is fixedly sleeved on the outer wall of the vertical pipe 901, and a sandwich layer is formed between the inner wall of the outer sleeve pipe 902 and the outer wall of the vertical pipe 901. One end of the water inlet pipe 904 is fixedly connected to one side of the bottom of the outer sleeve pipe 902, and the water inlet pipe 904 is communicated with the lower part of the sandwich layer. The other end of the water inlet pipe 904 is connected with a water supply assembly 10. One end of the return pipe 903 is fixedly connected to one side of the top of the outer sleeve pipe 902, and the return pipe 903 is communicated with the upper part of the sandwich layer. The lower end of the return pipe 903 is connected to the water storage part. The water supply assembly 10 is located inside the water storage part, and the water supply assembly 10 includes a water pump 1001, a first pipe body 1002, and a second pipe body 1003. The water outlet of the water pump 1001 is communicated with the second pipe fitting through the first pipe fitting, and the second pipe fitting is communicated with the lower end of the water inlet pipe 904.

[0054] After the air is purified of formaldehyde by the nano formaldehyde removal assembly 5, it enters the condensation assembly 9 through the tee pipe 8 for condensing and collecting the water in the air. The water in the cold water tank 6 is pumped by the water pump 1001. The cold water sequentially passes through the first pipe body 1002 and the second pipe body 1003, then enters the water inlet pipe 904, and then enters the sandwich layer formed between the vertical pipe 901 and the outer sleeve pipe 902. Then it flows back to the cold water tank 6 through the return pipe 903, so that the outer wall of the vertical pipe 901 is wrapped by cold water. The air enters the vertical pipe 901 for condensation. The water vapor therein condenses into a liquid state, flows along the vertical pipe 901 into the tee pipe 8, and then enters the cold water tank 6 to achieve collection. The air after condensation treatment is discharged from the top end of the vertical pipe 901.

[0055] The nano formaldehyde removal assemblies 5 are distributed in a rectangular array. The first pipe body 1002 is a multi-way pipe, such as Figure 3 , Figure 5 and Figure 7 shown. As an embodiment, the nano formaldehyde removal assemblies 5 are arranged in a 3×3 rectangular array. The first pipe body 1002 is a four-way pipe. One pipe orifice is connected to the water pump 1001, and the other three pipe orifices are respectively connected to a second pipe body 1003. A single second pipe body 1003 is used to connect a single row of condensation assemblies 9, so as to realize the connection between all the condensation assemblies 9 and the water pump 1001.

[0056] Such as Figure 5 and Figure 6As shown, the water storage part includes a cold water tank 6 and a water filling port 602 provided on one side of the top of the cold water tank 6. A sealing cover 603 is installed on the water filling port 602 for opening and closing the water filling port 602. The cold water tank 6 is used to store water, and water is added through the water filling port 602. The humidifying mechanism further includes an atomizing assembly 11. The atomizing assembly 11 includes a pump body 1101, a water suction pipe 1102, a water outlet pipe 1103, and an atomizing nozzle 1104. The pump body 1101 is installed on the top plate 601 of the cold water tank 6. The water inlet of the pump body 1101 is connected to one end of the water suction pipe 1102, and the other end of the water suction pipe 1102 extends downward and is close to the bottom surface of the cold water tank 6. The water outlet of the pump body 1101 is connected to one end of the water outlet pipe 1103, and the other end of the water outlet pipe 1103 is connected to the atomizing nozzle 1104. The atomizing nozzle 1104 is located inside the lower port of the tee pipe 8.

[0057] When humidification is required in the case of dry air, the pump body 1101 sucks the water in the cold water tank 6 through the water suction pipe 1102, enters the atomizing nozzle 1104 through the water outlet pipe 1103 for spraying, enters the tee pipe 8, and is discharged together with the air flow to achieve humidification.

[0058] As Figure 6 and Figure 8 As shown, a diversion cap 12 is provided above the atomizing nozzle 1104. A plurality of connecting seats 1201 distributed in an annular array are fixedly connected to the periphery of the diversion cap 12, and the connecting seats 1201 are fixedly connected to the inner wall of the tee pipe 8. A connecting strip 1202 is fixedly connected to the lower part of the diversion cap 12, and the lower end of the connecting strip 1202 is fixedly connected to the atomizing nozzle 1104.

[0059] The diversion cap 12 is used to block the top of the atomizing nozzle 1104. The diversion cap 12 is designed in a conical shape. The condensed water generated by the condensation assembly 9 flows to the lower end through the tee pipe 8 and is diverted through the diversion cap 12 to avoid dripping onto the atomizing nozzle 1104. After diversion, it flows into the cold water tank 6.

[0060] A humidifying method, the humidifying method includes the following steps:

[0061] First, formaldehyde decomposition. The air outside the body 1 sequentially passes through the air inlet 2 and the air inlet chamber and enters the nano-formaldehyde removal component 5, and flows along the decomposition coil 502. During the flowing process, it is irradiated by the ultraviolet lamp strip 5023, and at the same time, the entering air contacts the nano-catalytic layer 5022 and the nano-catalytic sheet 5024 to achieve formaldehyde decomposition and removal.

[0062] Second, heating. During the process of the air flowing through the decomposition coil 502, the heating wire 5025 is heated, and the heat is conducted through the nano-catalytic sheet 5024 to spread the heat into the decomposition coil 502.

[0063] III. Condensation: After the air is de-formaldehyde-treated, it enters the vertical pipe 901 through the three-way pipe 8. The water pump 1001 pumps the water in the cold water tank 6. The cold water successively passes through the first pipe body 1002 and the second pipe body 1003, then enters the water inlet pipe 904, and then enters the interlayer formed between the vertical pipe 901 and the outer sleeve pipe 902. Then it flows back to the cold water tank 6 through the return pipe 903, so that the outer wall of the vertical pipe 901 is wrapped by cold water. The air enters the vertical pipe 901 for condensation. The water vapor therein condenses into a liquid state, flows along the vertical pipe 901 into the three-way pipe 8, and then enters the cold water tank 6 to achieve recovery;

[0064] IV. Humidification: The pump body 1101 pumps the water in the cold water tank 6 through the water suction pipe 1102, enters the atomizing nozzle 1104 through the water outlet pipe 1103, and sprays it out. The water mist enters the three-way pipe 8, circulates with the air flow, is discharged from the inner box body 4 through the vertical pipe 901, and then is guided by the air guiding square pipe 7 and discharged from the air outlet 3.

[0065] Working principle: The intake fan 201 at the air inlet 2 blows air into the machine body 1. The air enters the top of the inner box body 4, enters the decomposition coil 502 through the inlet cover 501, and circulates along the decomposition coil 502. During the circulation process, it is irradiated by the ultraviolet lamp strip 5023. At the same time, the entering air contacts the nano-catalytic layer 5022 and the nano-catalytic sheet 5024 to achieve formaldehyde decomposition. Through the design of the coiled shape of the coil, the flow path is increased. Through the Figure 4 distribution design of the nano-catalytic layer 5022 and the nano-catalytic sheet 5024 as shown, the contact surface is increased to ensure the decomposition of formaldehyde;

[0066] A heating wire 5025 is additionally provided in the nano-catalytic sheet 5024. When the formaldehyde concentration in the air is low, there is no need to heat through the heating wire 5025. When humidification is not required in the above situation, during the process of formaldehyde decomposition to produce carbon dioxide and water, heat is released, which increases the temperature of the flowing air. The air enters the condensation assembly 9 for condensation treatment. The water pump 1001 pumps the water in the cold water tank 6. The cold water sequentially passes through the first pipe body 1002 and the second pipe body 1003 and then enters the water inlet pipe 904, and then enters the interlayer formed between the vertical pipe 901 and the outer sleeve pipe 902, so that the outer wall of the vertical pipe 901 is wrapped by cold water. The air enters the vertical pipe 901 for condensation, and the water vapor therein condenses into a liquid state and flows along the vertical pipe 901 into the three-way pipe 8, and then enters the cold water tank 6 for collection. When humidification is required in the above situation, the humidity sensor 702 detects that the humidity of the discharged air is insufficient, and additional humidification is performed through the atomization assembly 11. The pump body 1101 pumps the water in the cold water tank 6 through the water suction pipe 1102, enters the atomizing nozzle 1104 through the water outlet pipe 1103 and is sprayed out, enters the three-way pipe 8, and flows out together with the air flow to achieve humidification.

[0067] When the formaldehyde concentration in the air is high, heating is performed through the provided heating wire 5025, and heat conduction is carried out through the nano-catalytic sheet 5024, which is convenient for the heat to diffuse to the decomposition coil 502 to provide uniform heating for the air therein. Through heating, the formaldehyde degradation rate is increased.
