Description

Technical Field

[0001] The utility model belongs to the technical field of filter screen components, and in particular relates to an air-conditioning filter screen component. Background Art

[0002] In the early days, due to the complexity of the urban environment and the severity of industrial pollution, indoor air quality was seriously threatened. In order to improve the indoor environment, people began to seek various methods to filter pollutants in the air. With the advancement of science and technology, air conditioning filter technology came into being and gradually gained wide application.

[0003] The main function of air conditioning filters is to filter out harmful substances such as dust, bacteria, viruses, pollen, etc. in the air and improve the indoor air quality. Different types of air conditioning filters use different filter materials and filter technologies to achieve better filtering effects. For example, some high-end air conditioning products use negative ion filter technology, which combines negative ions with polluted particles in the air to achieve sedimentation and purification. In addition, some air conditioning filters use a multi-layer composite structure, which uses different levels of filter materials to effectively filter various pollutants in the air.

[0004] The disadvantages of air conditioning filters may vary depending on the type and quality. Here are some common disadvantages of air conditioning filters: 1. Limited filtration effect: Some types of air conditioning filters, especially those that rely on a single filter layer, may not be able to effectively filter out fine dust particles, germs, PM2.5 particles and harmful gases. This may lead to poor indoor air quality and pose a potential threat to the health of occupants. 2. Large wind resistance: Some high-efficiency air conditioning filters, such as high-efficiency particulate (HEPA) filter layers, may cause large wind resistance due to their tight structure, thereby affecting the ventilation volume of the air conditioner. This may reduce the effectiveness of the air conditioner and even increase energy consumption.

[0005] Therefore, the present application provides an air conditioning filter assembly, which can expand the built-in filter element of the filter through a built-in air expansion support frame structure, and assist in completing the fitting of the filter element and the support frame and unfolding it as much as possible to complete the filtering process. Since high-quality filter elements have a certain thickness, they cannot be fully unfolded due to space problems after being placed in the filter, resulting in a local high filtration density of the filter element, which affects the filtering effect. Therefore, compared with previous metal and other plastic structures, the built-in air expansion support frame can more effectively fit the filter element and complete the unfolding and filtering process. Its conical design reduces wind resistance and retains a certain amount of airflow space. Summary of the invention
