Virus isolation type mask

Abstract

The invention belongs to the technical field of masks, and particularly relates to a virus isolation type mask. At present, various masks, including medical masks, N95 masks and various electric masks, cannot completely and effectively isolate virus infection. The invention aims to provide a mask capable of effectively isolating viruses. According to the mask, a functional structure for killing viruses through ultraviolet rays is additionally arranged in an air filtering system of the mask, so that viruses including novel coronavirus can be instantly inactivated, a wearer can normally work and freely move without virus infection, and the mask is suitable for preventing virus infection when public plague occurs. The mask can filter particles and harmful gas in air, and a user can use the mask to prevent air pollution.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to a virus-isolated mask. Background technique [0002] New coronaviruses, influenza viruses, etc. can spread in the air in the form of droplets and aerosols. To prevent virus infection, people mainly wear medical disposable masks and N95 masks. According to data, considering that the mask is not tightly sealed, when inhaling, a negative pressure is formed inside the mask, and part of the polluted gas can enter from the edge of the mask. According to comprehensive evaluation, medical disposable masks can block about 50% of viruses, and N95 masks can block 50% of viruses. Blocking 70% of the virus, this situation does not effectively isolate the infection of the virus. [0003] In addition, people feel suffocated when wearing medical masks for a long time. Wearing N95 masks for more than 4 hours may be detrimental to lung health and is not suitable for long-term wearing. [0004] Bot...

Problems solved by technology

According to data, considering that the mask is not tightly sealed, when inhaling, a negative pressure is formed inside the mask, and part of the polluted gas can enter from the edge of the mask. According to comprehensive evaluation, medical disposable masks can block about 50% of viruses, and N95 masks can block 50% of viruses. Blocking 70% of the virus, this situation does not effectively isolate the infection of the virus

[0003] In addition, people feel suffocated when wearing medical masks for a long time. Wearing N95 masks for more than 4 hours may be detrimental to lung health and is not suitable for long-term wearing.

[0004] Both medical masks and N95 masks are disposable items and are not suitable for repeated use. Like many disposable plastic products, they will cause waste of resources and environmental pollution, and the cumulative cost of long-term use is high

[0005] In order to overcome the shortcomings of disposable masks, reusable electric masks have entered the market, such as an electric mask (Chinese patent application number: 201820141818.9), which uses an electric fan to assist air supply, which reduces the feeling of breathlessness, but the filter, battery , The motor and the fan are all integrated on the mask, which is restricted by weight, volume, power and noise factors. There are low air filtration accuracy, heavy weight, short continuous working time of the battery, high noise and large vibration, and it cannot effectively isolate viruses. Customers The wearing experience is poor, and it is inconvenient to clean after use

[0006] Another respirator (Chinese patent authorization number: CN102781520B) integrates the filter screen, battery, motor and fan into one, utilizes the neck space, and improves the load-bearing aspect compared with the mask all-in-one machine. Filtration accuracy, but because the mask and neck parts are integrated, it interferes with the rotation of the human head

In addition, because the smallest particle size of the virus is only 0.01 microns, the filter alone cannot effectively filter out the virus. The machine also has the disadvantage of a complex structure, which increases the burden on the neck

[0007] Another split-type wet type electric anti-virus and anti-haze mask (Chinese patent application number: 201620099670.8) uses filter cotton as the main filter layer, which has low filtration accuracy and can only block saliva droplets. Activated carbon can only filter harmful The role of the gas, the mask can not effectively filter out the virus

[0008] To sum up, at present, all kinds of masks, including medical masks, N95 masks and various electric masks, cannot effectively isolate the infection of the virus. This is a major technical problem that needs to be solved urgently. The spread of the new coronavirus, or future use to isolate other virulent viruses, is of great significance in the world
