[0041] The working principle and use process of the present invention are as follows: when in use, the circulating air is injected into the interior of the collecting box 15, and the airflow enters the shell 1 through the filtration of the filter plate 14. The dust contained in the airflow is blocked by the filter plate 14 and falls into the interior of the collecting box 15 for collection. When the airflow is evenly distributed to the interior of the shell 1 through the flow hole 11, the airflow contacts the biological filter material 9, the nano coil 8 and the activated carbon ring 7 in sequence. The harmful substances contained in the airflow are adsorbed by the microporous structure inside the above materials, thereby reducing the flow of harmful substances. At the same time, the airflow is continuously guided into between the sleeve 12 and the guide tube 2, and the ultraviolet lamp tube 3 emits ultraviolet light. Under the irradiation of ultraviolet light, the photocatalyst material 4 coated on the inner wall of the guide tube 2 undergoes a photocatalytic reaction to produce active substances such as holes, hydroxyls and superoxide free radicals with strong oxidizing ability, which can oxidize and decompose formaldehyde. At the same time, the airflow directly in contact with the ultraviolet light can reduce the transmission of harmful bacteria inside under ultraviolet irradiation, thereby further improving the filtering and protection effect. The sterilized airflow is discharged through the top of the shell 1 and used.

[0042] To sum up: the air conditioning filter element with high efficiency in degrading formaldehyde reduces the flow of harmful substances through the microporous structure inside the adsorption material 5 containing harmful substances in the air flow, and at the same time the ultraviolet lamp tube 3 emits ultraviolet light. Under the irradiation of ultraviolet light, the photocatalyst material 4 coated on the inner wall of the guide tube 2 undergoes a photocatalytic reaction to produce active substances such as holes, hydroxyl groups and superoxide free radicals with strong oxidizing ability, which can oxidize and decompose formaldehyde, reduce the formaldehyde content and have a sterilizing effect on bacteria. The present invention can improve the structural functionality of the existing air conditioning filter element, assist in filtering dust, and when the formaldehyde inside the new car is not completely volatilized, it can avoid the closed environment formed after the air conditioning causing harm to the driver's health safety.
