Embodiment 1

[0034] A breathable mask, such as Figure 1-Figure 3 As shown, the mask body 10 and the ear straps 20 symmetrically arranged on both sides of the mask body 10 are included. The mask body 10 is provided with some evenly spaced ventilating parts 30, and each ventilating part 30 is equipped with a detachable air-permeable filter. Structure 40, the detachable air-permeable filter structure 40 includes a plug-in joint 41 that is plugged and fitted with the air-permeable part 30, and one end of the plug-in joint 41 is coaxially connected with a limit seat 42, and a coaxial spacer is provided on the plug joint 41 and the limit seat 42. Vent hole 44, the end of plug joint 41 away from limit seat 42 is plugged with pressing device 43, and pressing device 43 comprises the pressing head 432 that inserts with vent hole 44, and one end of pressing head 432 is equipped with seal ring 431, presses The head 432 and the sealing ring 431 are provided with a coaxial air vent 433, and an end of t...

Embodiment 2

[0045] As a second embodiment of the present invention, the air-permeable filter element 435 is made of antibacterial filter material.

[0046] Further, the antibacterial filter material is a composite film of polymer nanofiber and support body non-woven fabric, wherein, the thickness of the polymer nanofiber film layer containing antibacterial agent is 5-15um, and the diameter of the polymer nanofiber in the film layer 500-700nm.

[0047] Specifically, the antibacterial filter material is made of antibacterial agent, polymer nanofiber and support body non-woven fabric, and the weight ratio of antibacterial agent, polymer nanofiber and support body non-woven fabric is 2-10:15-25:80- 90.

[0048] It is worth noting that the polymer nanofiber is one of polyethersulfone or polyvinylidene fluoride.

[0049] In the air-permeable mask of the present embodiment, the air-permeable filter core 435 is made of antibacterial filter material, which not only has excellent air permeability...

Abstract

The invention belongs to the technical field of masks and relates a breathable mask and a manufacturing method thereof. The breathable mask comprises a mask body and ear hanging belts symmetrically arranged on the two sides of the mask body; the mask body is provided with a plurality of breathable parts which are evenly arranged at equal intervals; each breathable part is provided with a detachable breathable filtering structure; each detachable breathable filtering structure comprises a connecting plug matched with the corresponding breathable part in an inserted mode; and one end of each connecting plug is coaxially connected with a limiting base, and coaxial breathable holes are formed in the connecting plug and the limiting base. According to the mask, the breathable parts are installed on the mask body; the detachable breathable filtering structures are installed on the breathable parts; when the mask is replaced, the detachable breathable filtering structures can be detached, an inner breathable filtering element can be replaced; since different kinds of breathable filtering elements can be replaced, the mask is suitable for being used in different environments; replacement is safe and sanitary; resources can be saved; and the breathable filtering element has excellent breathability, so that harmful substances in the air can be filtered out.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to a breathable mask and a manufacturing method thereof. Background technique [0002] Today's world economy is developing rapidly, and people's living standards have improved significantly. However, economic development has also brought serious environmental problems. The residues discharged from combustion during industrial production, daily power generation, and vehicle exhaust emissions have a huge impact on human respiratory health. Especially the very fine particles (PM 2.5) with a diameter of less than 2.5um in the air, they are the biggest culprits that cause atmospheric haze and human lung cancer. In addition to dust particles in the air, bacteria and viruses also exist, and they usually attach to suspended particles in the air and spread with the air flow. With the improvement of residents' living standards, consumers' demand for masks will also maintain rapid growth. Th...
