The present disclosure relates to the field of air purification, and in particular to an air filter that is easy to replace and install.
Air filters can filter particulate contaminants, germs, etc., to help improve air quality and reduce the spread of germs. As people's requirements for air quality increase, the air filters are increasingly used in malls, hospitals, laboratories, factories, etc. After a period of use, the air filters will adsorb a large amount of particulate contaminants, etc., which not only will result in a reduction in the rate of air exchange, but more importantly, will result in a significant reduction in the air purification effect. In order to ensure the air purification effect, the air filters need to be replaced or purified.
A conventional air filter includes a frame, inside which a filter element is fixed. The frame and the filter element are fixed in one piece, and are replaced as a whole during replacement. Such an integrated air filter is expensive to manufacture and occupies a large space, resulting in a corresponding increase in the cost of transportation. The frame of the air filter is generally made of an alloy material or an alloy-containing composite material, whereas the filter element is generally made of a polymer material such as non-woven fabric. The frame and the filter element use different materials, and thus need to be recycled separately, making recycling difficult and the recycling cost relatively high.
As China pays more and more attention to environmental protection and the requirements for the recycling of waste are getting higher and higher, people have to consider the costs associated with the disposal of waste materials when using air filters. These costs include, but are not limited to, the cost of transporting the waste to landfills or incinerators, the cost of treating the waste prior to disposal, and the cost of disposing of the waste in landfills or incinerators. It is foreseeable that the cost of conventional integrated air filters will increase further as environmental regulations become stricter due to the difficulty in recycling. Outdated air filters do not conform to the concept of sustainable development and are not environmentally friendly. Therefore, it is necessary to develop a new type of air filter.
An objective of the present disclosure is to provide an air filter that is easy to replace and install, in order to overcome at least one of the deficiencies of the prior art.
A technical solution adopted by the present disclosure is:
In some examples of the air filter, the edge strip is provided with slots at two ends thereof, and the corner connector is provided with corresponding joints.

In some examples of the air filter, a surface of the filter element is provided with two or more flexible cords.
In some examples of the air filter, the pleats are provided with side leakage protection filter layers at two ends thereof, and a surface of the filter element is provided with two or more flexible cords.

The present disclosure has the following beneficial effects.
The air filter of some examples of the present disclosure can be conveniently disassembled in situ, and can be disassembled into components during storage and transportation, thereby reducing the space occupied during the storage and transportation, and facilitating the reduction of the cost of storage and transportation.
In some examples of the air filter of the present disclosure, the frame can be reused, thereby producing less waste and being more environmentally friendly. It is also possible to replace only damaged components when the frame is damaged, so that the cost of maintenance is low.
In some examples of the air filter of the present disclosure, it is possible to replace only the filter element, so that the cost of use is also significantly reduced.
In some examples of the air filter of the present disclosure, by providing the flexible cord between the pleats, the reduction of the local effective filtering area caused by too large or too small pleat spacing is avoided, and the air purification effect is effectively guaranteed.

With reference to
The edge strips 1 and the corner connectors 2 are connected to each other via mortise and tenon structures. The edge strips 1 and the corner connectors 2 are connected to each other to form a frame 4.

The frame can be simply assembled on site, and can be disassembled and packaged separately during storage and transportation, occupying little space, and facilitating the reduction of the cost of storage and transportation. When the filter element needs to be replaced, it just needs to directly remove the filter element and fix a new filter element within the frame by means of a connection member. It is also possible to replace only damaged components when the frame is damaged, so that the cost of maintenance is low. The flexible cord is easy to fold, and the pleats can have and maintain the designed maximum spacing after unfolding the flexible cord.
