Background

The air filter is an air cleaning and purifying device, can effectively remove pollutants in indoor air, and is required to be provided with a corresponding air purifier for filtering particles and microorganisms in the air in some important places according to national requirements.

The central air conditioning system is usually provided with a combination arrangement mode of fresh air and a fan coil unit, and the main means of indoor air treatment is carried out by adopting a fan coil, wherein an air return filter is mainly adopted for treating air particles and microorganisms. The filter installed in the fan coil return air belongs to the consumable, and the structure of the return air purifier is easy to install, and the air purifying core body is easy to install, convenient to detach and replace regularly.

At present, in the air cleaner installation, install the framework structure earlier, put into the core again, adopt fixed subassembly to fix the core filter again, open fixed subassembly when changing, take out the core and realize filter replacement, but at actual operation in-process, air cleaner installs at furred ceiling dragon skeleton and often has following problem:

1. the frame body frame needs to be locked to the keel by the screws, and the problems that the frame body is deformed by transverse pulling, so that the core body is unstable to fix and easy to fall off exist.

2. The return air passes through this type of air filter, and there are two airtight leak points: the connection surface of the core body and the fixing component and the connection surface of the fixing component and the frame body, especially when the length of the filter is longer, the two airtight leakage points often have the phenomenon of air leakage, if the filter is transversely pulled in installation, the airtight leakage points are more likely to occur to cause air to escape from the leakage points, and the filtering effect cannot be achieved

3. The filter element periphery, the frame body periphery and the fixed components are assembled with each other: there are margin pauses and package pauses. When there is a limit in the installation space, the effective use width and the use section of the filter element are reduced due to the intermittence, so that the section wind speed tends to be increased, and the problem of the increased air flow passing resistance is caused under the condition of the same filter element body materials and structures. In particular, a strip-type air purifier, such as: the width of the frame body is 250mm, the width of the two frame bodies, the width of the two side filter elements, the width of the two side fixing assemblies, the two side allowance intermittence and the two side packaging intermittence are greater than or equal to 40mm, the effective width is less than or equal to 210mm, the effective width is reduced by at least 16%, and the air flow passing speed is increased by 19% under the condition that the filter lengths are the same, so that the problem of increasing the initial resistance of the whole system is caused.

4. The air filter comprises: the filter element, the frame body and the fixing component are produced in batches and transported in batches, and the filter element and the frame body are required to be packaged independently, so that the cost and the transportation cost are increased synchronously, and the large-area popularization is not facilitated.

5. The air purifier has a plurality of components, and is installed in complex installation steps on site: the frame body, the core body and the fixing component consume man-hour; after the filter is installed, the return air port is installed, so that the working procedure is time-consuming and the installation cost is high. When the air return port is replaced, the air return port is required to be taken down, and then the filter is replaced, so that the air return port is relatively complex and is not beneficial to frequent replacement of consumable materials.
