Self-conversion type multipurpose mask and conversion using method thereof

Abstract

The invention belongs to a self-conversion type multipurpose mask and a conversion using method thereof. The self-conversion type multipurpose mask is composed of a left butt joint barrel, a right butt joint barrel, a compression spring, a valve block, an adjusting screw ring, an air outlet filter box, an air inlet filter box and a filter material. And the filter material is a fiber sheet, an activated carbon mixed adsorbing material or a sterilization mixed adsorbing material. According to the method, the structure of the mask is changed according to the purposes of a user, and the purposes comprise a single-port dustproof structure, a double-port dustproof structure, a one-way dustproof and anti-virus structure, a double-port dustproof and anti-virus structure and a two-way dustproof andanti-virus structure. According to the purposes of the mask, the structure of the mask can be changed rapidly in a self-service mode, the mask can be changed rapidly in a self-service mode and has the two-way anti-virus and dustproof effects, and the mask has the advantages of being simple in structure, multipurpose, convenient to use and disinfect and good in effect.

Description

technical field [0001] The invention belongs to a self-conversion multipurpose mask and a conversion and use method thereof. Background technique [0002] Various well-known or unknown viruses have greatly endangered human health, especially some viruses such as "new coronavirus" are highly contagious, and the transmission channels are mainly droplet infection and contact infection. Patients transmit droplets to others through breathing, so An ideal anti-virus mask should have a two-way anti-virus effect, which can prevent the wearer from invading external viruses and prevent the exhaled virus carried by the wearer from leaking out. But such products are currently lacking. Chinese patent announcement number CN2606607Y discloses a kind of " anti-virus dust-proof anti-smoke protective cover " though has two-way anti-virus effect, but its structure is complicated, uses single, split property is poor, wears numerous cables, practicality is poor, is difficult to popularize. [...

AI Technical Summary

Problems solved by technology

Chinese Patent Notification No. CN2606607Y discloses a "anti-virus, dust-proof, and smoke-proof protective cover", although it has a two-way anti-virus effect, but its structure is complex, single use, poor separation, wearing complicated cables, poor practicability, and difficult to popularize

[0003] An ideal mask should be structured according to its purpose. For example, if it is only used as a dust-proof and anti-fog mask, it only needs to filter out the tiny dust in the inhaled air, and it does not need to filter the wearer's exhalation, otherwise it will be too much. Functional design will increase the use of materials and increase the cost

[0004] The production of protective equipment such as masks is relatively complicated, the cost of materials is high, and labor-intensive. During the plague period, the supply is in short supply, and most of them are disposable items, which cause serious waste and environmental pollution.

However, there is currently a lack of multi-purpose designs that can self-help and quickly change the structure of the mask according to the use of the mask
