Example Embodiment

[0021] Example one

[0022] The basic structure of the antivirus filter of this embodiment is as follows figure 1 , 2 As shown, it includes a filter body 4 and its supporting frame 2. The filter body 4 is a multilayer filter material structure. The multilayer filter material structure of this embodiment includes two layers of electrostatic electret filter material; the support frame 2 Taking the air inlet direction as the reference, there are three sets of supporting vertical pieces 2-2 extending inward from the air inlet plane 2-1, which are perpendicular to the air inlet plane. The distance between adjacent supporting vertical pieces in this embodiment is 10mm~ 50mm; the inner side wall of the support frame is connected to the periphery of the filter body in a sealed manner, and the outer periphery is connected to the external structure 1 through a fixing member 3. The thickness of the supporting sheet 2-2 itself is very small, so it occupies a small air inlet area, and the air...

Abstract

The invention provides an antivirus filter. The antivirus filter comprises an outer structure located at an air outlet and further comprises a support frame and a multilayer filter material structure. The support frame is in seal connection with the outer structure through a seal structure. The multilayer filter material structure is arranged in the support frame in parallel. The multilayer filter material structure comprises a first filter layer and a second filter layer. The support frame comprises an air inlet support. At least one set of multilayer filter material support sheets are arranged in the air inlet support and are perpendicular to the inner surface of the air inlet support. The antivirus filter has the effects of better efficiency and better gas permeability in the aspect of filtering of viruses. The antivirus filter can reach the penetration rate lower than one thousandth for viruses, and the purpose of protection of human health is met effectively. If the technical standards of the two layers of filter materials are improved to 5% and 1% correspondingly, the penetration rate which cannot be detected can be achieved, and the antivirus filter can be used for very strict protective occasions. Due to the fact that the windage resistance of the combined filter materials of the technology belongs to the low windage resistance range, after combination, the windage resistance is still lower than that of filter materials of which one single layer is used and has a very high filtering effect on particulate matter.

Description

technical field [0001] The invention relates to an antivirus filter, which belongs to the field of air cleaning appliances. Background technique [0002] In places such as hospitals and scientific research laboratories, there may be a danger of pathogenic viruses and their attachments suspended in the air. For some people with poor physique or patients, a small amount of virus may also pose a greater threat when exposed to polluted air. Viruses are only about one-hundredth the size of bacteria and have no cellular structure. Some viruses are about 100 nanometers (0.1 microns) in size, but there are also very small common viruses, such as coronaviruses that are 30 nanometers (0.03 microns), and foot-and-mouth disease viruses that are as small as 7-8 nanometers. The existing air purification filter has a better filtering effect on larger particles, such as 2.5 micron and 0.3 micron particles, and also has a certain effect on bacteria, but for viruses, it can easily pass thro...
