[0046] The preparation method of the water chestnut bark extract is as follows: the water chestnut bark is dried at 50° C. for 24 hours, and then soaked in deionized water at a mass volume ratio of 1:4 (g / mL), and the temperature of the deionized water is 8 ℃, soaked for 2 hours, extracted at 70 ℃ for 3 hours, filtered through a 100-mesh filter cloth to obtain filtrate A and water chestnut skin filter residue; deionized water with 6 times the mass of the water chestnut skin filter residue was added to the obtained water chestnut skin filter residue, and the temperature was continued at 80 ℃. Extracted for 2 hours, and then filtered through a 100-mesh filter screen to obtain extract B; combined extract A and extract B, placed in a rotary evaporator with a temperature of 60 ° C and an absolute pressure of 0.05 MPa, and concentrated until the remaining volume was the original Up to 5% of the volume, a water chestnut bark extract was obtained.

Embodiment 1
[0054] An air purifier prepared from the following raw materials by mass percentage: 0.5% sodium perchlorate, 0.1% tartaric acid, 0.05% sodium laureth sulfate, 0.2% polyacrylamide, 1 glycerol %, citral 0.1%, alumina 0.5%, titanium dioxide 0.5%, modified diatomaceous earth 0.5%, modified attapulgite 0.5%, melamine 0.5%, plant extract 1.5%, the balance is deionized water.
[0055] The plant extract is prepared by mixing water chestnut bark extract, Agaricus extract, and Dendrobium extract in a mass ratio of 1:1:1.
[0056] The preparation method of the modified diatomite is as follows: adding diatomite to 0.1mol / L Fe(NO) 3 ) 3 Impregnated in aqueous solution, the diatomite, Fe(NO 3 ) 3 The mass-volume ratio of the aqueous solution was 1:3 (g / mL), stirred for 40 min at 30 °C and 600 r / min, then microwaved at 40 °C and microwave power of 560 W for 5 min, and finally at 50 °C After drying for 8h, modified diatomaceous earth was obtained.
[0057] The preparation method of the ...
Embodiment 2
[0067] It is basically the same as Example 1, the only difference is that: the plant extract is prepared by mixing water chestnut bark extract and Agaricus radix extract in a mass ratio of 1:1.
