Problems solved by technology

[0003] Existing conventional medical and civilian masks can only block conventional larger dust, and it is difficult to effectively filter and adsorb PM2.5 pollutants; although there are now masks that can absorb and filter PM2.5 on the market, However, because it is only a thickened ordinary mask, the filtering effect is poor and it is easy to cause poor breathing. When wearing a soft mask, it will fit on the nasal cavity, causing discomfort to the user.
[0004] The adsorption layer of PM2.5 exists as an existing technology, but due to its small pore size, fans are usually required to strengthen the air flow to make the air flow pass smoothly. If it is applied to masks or other human devices, It will cause poor breathing and completely fail to achieve the purpose of filtering the airflow.

Embodiment 1

[0029] Such as figure 1 The dust filtering, sterilizing and purifying component shown is a layered structure consisting of an outer layer, an inner layer and an intermediate layer, the intermediate layer includes a PM2.5 filter layer, and the PM2.5 filter The layer comprises the first honeycomb photocatalyst filter screen layer, the first solid-loaded nano-titanium dioxide filter screen layer positioned on one side of the honeycomb photocatalyst filter screen layer, and the second solid-loaded nano-titanium dioxide filter screen layer positioned on the other side of the first solid-loaded nano-titanium dioxide filter screen layer. Two honeycomb photocatalyst filter screen layers and the second solid-carrying nano-titanium dioxide filter screen layer positioned at the other side of the second honeycomb photocatalyst filter screen layer, the aperture of the first honeycomb photocatalyst filter screen layer is 0.4mm, thickness It is 0.32mm; The aperture of the second honeycomb ph...

Embodiment 2

[0031] Such as figure 1 The dust filtering, sterilizing and purifying components of the layered structure shown are respectively composed of an outer layer, an inner layer and an intermediate layer. The intermediate layer includes a PM2.5 filter layer, and the PM2.5 filter layer includes a first honeycomb Photocatalyst filter screen layer, the first solid-carrying nano-titanium dioxide filter screen layer positioned at one side of the honeycomb photocatalyst filter screen layer, the second honeycomb photocatalyst filter screen positioned at the other side of the first solid-carried nano-titanium dioxide filter screen layer layer and the second solid-loaded nano-titanium dioxide filter layer positioned at the other side of the second honeycomb photocatalyst filter layer, the aperture of the first honeycomb photocatalyst filter layer is 0.38mm, and the thickness is 0.45mm; The aperture of the honeycomb photocatalyst filter screen layer is 0.59mm, and the thickness is 0.29mm; the...

Embodiment 3

[0033] Such as figure 2As shown, the dust filtration, sterilization and purification mask includes the main body of the mask, the internal support, the replacement port of the main body of the mask, the gas replenishment ring and the lace, and the dust filtration, sterilization and purification components described above for the main body of the mask. The outer layer and the inner layer of the dust filtering, sterilizing and purifying component are both non-woven fabric layers; the inner supporting part is made of hard titanium alloy wire. The internal support part is a hemispherical shape adapted to the shape of the nasal cavity, which closely fits the face of the human body and has a small shape. The mask main body piece portion replacement opening with rubber band sealing as the elastic component is used to replace the mask main body piece portion, and the mask main body piece portion is wrapped in the mouth mask by the elastic component. The lace is a belt made of high-s...

Abstract

The invention discloses a dust filtering, sterilizing and purification unit which is in a layered structure. The dust filtering, sterilizing and purification unit comprises an outer layer, an inner layer and a middle layer. The middle layer includes a PM2.5-level strainer layer. The invention further discloses a dust filtering, sterilizing and purification mask comprising a mask main sheet, an inner support part, a mask main sheet replacement hole, a gas supplement ring, and a strap. Specifically, the PM2.5 can be filtered and sterilized, and a clean air environment is provided for human.

Description

technical field [0001] The invention relates to an air purification device, in particular to a PM2.5 dust filter, sterilization and purification layered component, and in particular to the application of a PM2.5 dust filter, sterilization and purification component in a mask. Background technique [0002] As common knowledge, PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere, also known as inhalable lung particulate matter. The diameter is less than 1 / 20 of a human hair. Due to its increasing harm to the human body, it has received more and more attention from people. According to the prediction of relevant agencies, this kind of pollution in China will continue, so various measures to prevent it from entering the human body need to be paid more and more attention. . [0003] Existing conventional medical and civilian masks can only block conventional larger dust, and it is difficult to effectively filter and adsorb PM2....
