Gas filter element

The present invention relates to a filter element, and more particularly to a gas filter element comprising a nanocomposite metal material.

Recently, due to factors such as industrial development and developed transportation, the environment is filled with dust, exhaust gas, bacteria, mold, viruses, and other particles that may cause harm to the human body, and therefore people with symptoms such as chronic respiratory allergies and chronic nasal allergies The more you come. As modern people's awareness of maintaining good health gradually rises, related devices that can be used for air filtration are gradually being taken seriously, and are widely used in daily life, such as air filters for vehicles, air cleaners, and the like. Among them, filter elements that provide filtration play a key and indispensable role in such devices.

In general, gas filter elements generally physically collect dust and other large particles to achieve a filtering effect, that is, the small pores in the filter material allow dust and other large particles to pass through to filter. Therefore, the porosity of the filter material itself is the difference between the filtering effect. When the porosity of the filter material is large, the gas permeability is better, and the gas flow rate is less affected (for example, for a vehicle air filter or air conditioner). When the filter screen has a low influence on the air flow rate, but the small size particles cannot be captured, the filtering effect is poor; relatively, when the porosity of the filter material is small, the gas permeability is poor, and the gas flow rate is affected. Large (for example, applied to When the vehicle air filter or the air conditioner filter has a large influence on the air flow rate, it can capture fine particles of a small size and has a better filtering effect.

As for the extremely small harmful substances such as bacteria and viruses, it is difficult to capture by physical means. If the cover is to be physically collected, the porosity of the filter material must become quite small to have a chance to filter. However, such pores A relatively small filter material is not suitable for use in devices with high gas flow requirements, such as automotive air filters or air conditioning filters. Therefore, there is a need for a filter element that has excellent filtration ability for particulates, bacteria, viruses, and the like, and has a good gas flow rate.

In the following, some embodiments according to the present invention will be described in more detail with reference to the accompanying drawings; however, the present invention can be practiced in various different forms without departing from the spirit of the present invention, and should not be construed It is limited to the embodiment illustrated in the specification. In addition, in the drawings, the dimensions of the various items and regions may be exaggerated for clarity, and are not shown in actual scale. In the meantime, the terms "a", "an" and "the"

The essence of the gas filter element of the present invention is that a nano composite metal particle capable of providing an antibacterial (viral) effect is successfully attached to the filter material, wherein the composite metal particle is embedded in the flexible filter material because of its nanometer size. Therefore, the influence on the porosity of the flexible filter material is relatively low, and the antibacterial (viral) effect and the good filtering effect can be provided without significantly affecting the gas flow rate. Without being bound by theory, the anti-bacterial and viral effects of Xianxin are derived from nano-silver particles. The anti-fungal effect is mainly from nano-copper particles, while the nano-titanium particles provide excellent antioxidant properties.

The flexible filter material 113 is configured such that the nano composite metal particles 111 are firmly adhered to the inside of the flexible filter medium 113. The nano composite metal particles can be formed by any conventional method, such as a precipitation method, a hydrolysis method, a spray method, a redox method, a sol-gel method, a thermal evaporation method, a vacuum sputtering method, etc., wherein a vacuum sputtering method is used. good. In the case of vacuum sputtering, not only the formed particles are relatively uniform in size (average particle size is from about 3 to about 60 nm), and the formed nano metal particles can be deeper into the interior of the flexible filter material, which is more robust. Adhesion allows the gas filter element to have a long service life. In addition, in the case of using the vacuum sputtering method, it is more necessary to adjust the content of the nano composite metal particles, so that the overall application flexibility of the gas filter element is higher. For example, in a gas filter element in which the flow rate is heavy, the nano composite metal particles may be plated at a lower content, so that the nano composite metal particles are formed substantially only on the surface of the flexible filter material portion, so that the nano composite metal particles are The presence of substantially no effect on the flow performance or the impact is extremely slight; and in the gas filter element where the antibacterial (viral) effect is heavy, the nano composite metal particles can be plated at a higher content, so that the nano composite metal particles substantially cover the flexible filter material.
