Abstract

This application provides an air purification component (100) and an air conditioning device (300). The air purification component (100) includes: an outer housing (1) that is cylindrical and rotatably arranged in an air duct (301); an opening (2) provided on a cylindrical surface of the outer housing (1); an inner housing (3) extending in an axial direction of the outer housing (1) and built into the outer housing (1); an opening (4) provided on a cylindrical surface of the inner housing (3); an ionizer fixing portion (5) disposed on an inner surface of the inner housing (3); and an ionizer (6) fixed to the ionizer fixing portion (5). During operation, the ionizer (6) adsorbs dust particles in the air. In a case where the outer housing (1) pivots around a central axis thereof under the drive of wind, a surface of a carbon fiber brush is periodically wiped when the ionizer (6) transitions from the outer housing opening (2) to the inner surface of the outer housing (1), thereby cleaning the dust particles accumulated on a surface of the ionizer (6). The device according to the embodiment of this application can be driven by wind to ensure a self-cleaning function with zero energy consumption of the ionizer (6).

Description

PRIORITY CLAIM This application claims benefit of Chinese Patent Application No. 202411611844.X, filed November 12, 2024, and all the benefits accruing therefrom under 35 U.S.C. §119, the contents of which in their entirety are herein incorporated by reference. BACKGROUND The present invention relates to the technical field of air purification devices, in particular to an air purification component and an air conditioning device having the air purification component. There are many problems with existing technologies and products in the field of treating chemical substances, particles, and biological contaminants in the air. The treatment cost is high, which brings about a great economic burden for practical applications. Meanwhile, the function and application range thereof are limited to some extent, and cannot fully meet the demands of different scenarios. In the aspect of a cleaning device of an air purification device, the products on the market generally need to be driven by a power device, which not only results in high energy consumption, but also results in a complex structure of the device and increases the difficulty of installation and maintenance. Moreover, the efficiency of traditional photocatalytic technologies tends to gradually decrease during use, making it difficult to maintain a stable treatment effect. In summary, current technologies and cleaning devices for treating contaminants are deficient in cost, function, efficiency, and structure. SUMMARY Aspects of the present invention aim to provide an air purification component to at least solve or alleviate some of the problems existing in the related art. It should be noted that working principles, features, advantages, and the like of the air purification component according to the present invention will be explained below by way of embodiments. However, it should be understood that all descriptions are only given for exemplification and therefore these embodiments should not be understood as forming any limitation on the present invention. Viewed from a first aspect, there is provided an air purification component including: an outer housing that is cylindrical and rotatably arranged in an air duct; an outer housing opening provided on a cylindrical surface of the outer housing; an inner housing extending in an axial direction of the outer housing and built into the outer housing; an inner housing opening provided on a cylindrical surface of the inner housing; an ionizer fixing portion disposed on an inner surface of the inner housing; and an ionizer fixed to the ionizer fixing portion such that an end of the ionizer faces the inner surface of the inner housing. Optionally, the ionizer is a carbon fiber brush, and the end of the ionizer extends to abut against the inner surface of the outer housing. A plurality of carbon fiber brushes may be arranged along the axial direction of the outer housing. The plurality of carbon fiber brushes may be additionally or alternatively uniformly arranged around the outer surface of the inner housing. Optionally, the outer housing opening is a grille bar arranged along the axial direction of the outer housing, and the inner housing opening is a honeycomb hole arranged on the cylindrical surface of the inner housing. An outer housing locking portion may be configured to lock and fix rotation of the outer housing such that the end of the ionizer faces the outer housing opening. The air purification component may further include a plurality of outer housing surface blades protruding from a surface of the outer housing at a predetermined angle relative to the surface of the outer housing. The outer housing surface blades may each be integrally formed by locally bending the outer housing. The air purification component may further include: an inner housing catalyst coating coated on the inner surface of the inner housing; and a light emitter disposed inside the inner housing. The light emitter may be an ultraviolet light emitter or a visible light emitter. Viewed from a second aspect, there is provided a control device for adjusting and controlling the air purification component according to the first aspect, the control device including: an outer housing locking portion action execution module configured to activate the outer housing locking portion to lock and fix rotation of the outer housing, and allow the outer housing opening to stop at a position corresponding to an end of the ionizer.
