Abstract

The invention relates to a 3D printing manufacturing method of a high-ventilation-capacity anti-virus and anti-smog sealing type mask. The 3D printing manufacturing method comprises the steps: scanning three-dimensional data of a human face in a three-dimensional mode; designing a mask body and an edge three-dimensional model of the mask by using three-dimensional reverse engineering software; carrying out soft and hard integrated 3D printing or die-casting molding by opening a die; providing the cover body with an air inlet channel and an air outlet channel; arranging three layers at the airinlet and outlet channels, setting the inner layer and the outer layer to be disposable filters, and arranging micro mute air supply and exhaust fans at the middle layer; and enabling entering air andexhausted air to arrive only through the air inlet channel and the air outlet channel. According to the invention, the personalized edge shape can be completely attached to the face skin of a wearer,and the mouth and the nose of the wearer are completely isolated from the outside; a fresh air system is formed in the inner space of the mask, so that effective ventilation of a wearer can be guaranteed on the premise that smog, viruses and the like are effectively and bidirectionally isolated, and problems that the edge of a mask body of a conventional mask is not sealed tightly or lung ventilation is affected are solved;and the mask can be repeatedly used by replacing disposable filter pieces of air inlet and outlet channels after surface sterilization.

Description

technical field

[0001] The invention relates to the field of sanitary protective products, in particular to a 3D printing manufacturing method of a high-ventilation anti-virus and anti-haze tight-fitting mask. Background technique

[0002] Although existing masks can basically solve the problem of respiratory isolation. However, the main problems include: 1. Masks made of uniform standards cannot effectively fit people with different face shapes. The skin is easily compressed and damaged; 2. The wearer cannot ventilate effectively and breathe normally; 3. The mask body is all made of disposable filter materials. When using filter materials below N100, some microscopic particles will leak out; and filter with N100 grade materials, can lead to excessive and even pathogenic ventilation resistance.

Embodiment Construction

[0019] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] A 3D printing manufacturing method of a high-ventilation anti-virus and anti-haze airtight mask of the present invention comprises the following steps:

[0021] 1) Three-dimensional scanning of the three-dimensional data of the human face;

[0022] 2) Design the mask body and edge three-dimensional model of the mask with three-dimensional reverse engineering software;

[0023] 3) Use the integrated 3D printing of soft and hard or die-casting molding, in which the cover body is made of airtight hard light-weight transparent material, and the edge area is made of soft transparent material;

[0024] 4) The two sides of the mask body corresponding to the mouth and nose are respectively provided with an air intake channel and an exhaust channel;

[0025] 5) There are three inner and outer layers at the inlet and exhaust channels, t...
