[0002] As people pay increasing attention to indoor air quality, air conditioning systems not only need to regulate temperature but also need to have air purification functions. Existing air purification equipment for air conditioners usually adopts a simple filtration structure, which can only filter large particulate pollutants in the air, but cannot effectively remove fine particles, bacteria, viruses, odors and other harmful substances. The purification efficiency is low, and the filter material is inconvenient to replace, resulting in high maintenance costs. Utility Model Content

[0005] The primary filtration chamber is located on the right side of the equipment box, the secondary filtration chamber is located on the left side of the primary filtration chamber, and the negative ion purification chamber is located on the left side of the secondary filtration chamber. The turbulence-disrupting component is installed on the left wall of the equipment box and is connected to the negative ion purification chamber. The air outlet is installed on the turbulence-disrupting component. The air inlet pipe is embedded on the right wall of the equipment box and extends into the primary filtration chamber. Non-woven filter cotton is filled in the combination frame, which is movably installed in the primary filtration chamber. The composite activated carbon filter packing is placed inside the secondary filtration chamber. A pair of sealing caps are movably inserted into the top openings of the primary and secondary filtration chambers. The negative ion generator is installed on the front wall of the equipment box, and its output end extends into the negative ion purification chamber.

[0006] Preferably, the primary filter chamber and the secondary filter chamber are provided with a combination slot at the top.

[0007] Preferably, a pair of sealing caps are mounted on the equipment housing by fixing bolts.

[0008] Preferably, the combination frame is equipped with a pair of lifting rods.

[0011] The connecting pipe is installed between the equipment box and the connecting air outlet hopper. The mounting cavity is opened inside the connecting pipe, and several straight baffles are vertically installed inside the mounting cavity.

[0012] Beneficial effects

[0013] This utility model provides an air purification device inside an air conditioner, which has the following beneficial effects: This solution uses a multi-stage turbulence purification structure. Through a three-stage design of a primary filtration chamber (non-woven fabric filter cotton), a secondary filtration chamber (composite activated carbon filter packing), and a negative ion purification chamber, it filters particulate matter, odors, and harmful gases in the air step by step, and uses negative ions for sterilization and disinfection, significantly improving the purification effect. The straight-line turbulence plate in the turbulence component can guide the airflow to form turbulence, reduce wind resistance, and reduce energy consumption. The combination frame adopts a detachable structure and is equipped with a lifting rod for easy and quick replacement of the non-woven fabric filter cotton. The sealing cover is fixed with bolts, ensuring the sealing of the cavity while also making it easy to open for cleaning or replacement of the purification packing, facilitating maintenance and cleaning. This solves the problem that existing air purification devices for air conditioners usually use simple filtration structures, which can only filter large particulate pollutants in the air, but cannot effectively remove fine particles, bacteria, viruses, odors, and other harmful substances, resulting in low purification efficiency, inconvenient filter replacement, and high maintenance costs.

The combination frame 7, installed within the primary filter chamber 2, facilitates complete replacement. The air after preliminary filtration then enters... The air then enters the secondary filtration chamber 3, where the microporous structure of the composite activated carbon filter media 9 adsorbs and purifies tiny particles and odor molecules in the air, further achieving purification. The air then enters the negative ion purification chamber 4, where the negative ion generator 11 releases negative ions to remove harmful substances such as bacteria and viruses, enhancing air freshness. After purification, the air enters the connecting pipe 16, where a straight-line baffle 18 ensures straight airflow, reducing turbulence and ensuring rapid, straight discharge through the connecting outlet hopper 5, thus reducing equipment power consumption.
