Air filtering device 3D printing method based on human face, and filtering device

Abstract

The invention discloses an air filtering device 3D printing method based on a human face, and the method comprises the steps: obtaining scanning data through various types of human face photographing and scanning technologies so as to obtain a digital model of the face of a user; importing the digital model into three-dimensional modeling software; generating a sealed part of a mask, a three-dimensional spatial structure of the mask and a cavity structure of the mask based on the human face digital model, carrying out the optimization and fine tuning of the sealed part and the structures, so as to guarantee the airtightness of the mask and the face and the optimal volume of a cavity; building a three-dimensional digital model of the mask through combining with the personalized design from a user and employing modeling software; determining a mask three-dimensional model, and transmitting the mask three-dimensional model to a 3D printer for printing; enabling an air filter to be embedded in the sealing part of the mask; and carrying out the binding of two side edges of a mask fixing part and the sealing part of the mask. The method can enable the mask to be matched with the facial profile of an individual, and reduces the leakage of air. The volume of the cavity in the mask is optimal, and the concentration of carbon dioxide is effectively reduced. The hardness of the sealing part can be adjusted to meet different demands of individuals.

Description

technical field [0001] The invention relates to the field of 3D printing, especially an air filter device made by using 3D printing technology and facial recognition technology, which is a mask made on the basis of a digital face model, adapted to the contour of the human face and tightly fastened and interface devices. Background technique [0002] At present, the number of smog days in some big cities in my country is increasing year by year, and air pollution has attracted more and more attention. Wearing a mask is the most effective means for people to protect against air pollution such as smog and car exhaust. The filtration efficiency of the mask, that is, the percentage of particles that the mask can filter out, is the basic indicator of the performance of the mask, and the leakage rate of the mask, that is, the degree of closeness between the mask and the face, is a key technical indicator that affects its filtration efficiency . At present, although the filter ma...

Problems solved by technology

[0004] At present, the masks on the market are all produced according to uniform size and specifications. Masks cannot be produced according to the face shape of a single user, and their shape cannot adapt to the different facial contours of many users, resulting in air leakage on the side and air leakage on the side. It is an important factor affecting the performance of the mask
