Description

Method for manufacturing customized mask for individual or animal

Technical Field

The invention relates to the technical field of wearable filtering equipment, in particular to a manufacturing method for customizing a mask for an individual or an animal.

Background

In recent years, personal protective articles such as masks and the like gradually become one of daily necessities of people along with the remarkable appearance of environmental problems such as haze, dust and the like and the outbreak of novel epidemic diseases. Meanwhile, people put higher demands on the protection grade, wearing comfort, customization and the like of personal protection articles.

The safety and the sealing performance of protective articles such as masks are derived from the protection grade of raw materials and the matching degree of the protective articles with human or animal related organs. However, due to natural individual differences in the size of the head and face of a human or animal, product wearing mismatches may result. Meanwhile, due to the limitation of the mask industrial production mode, the mask can only classify and merge the data required by the wearer, and the product is divided into a plurality of general size specifications. So that many wearers can't obtain good matching degree of wearing in the in-service use process of this kind of product, and the product does not laminate with relevant organ of people or animal, and the product is easy not hard up, is shifted in the motion, and then influences leakproofness, the travelling comfort of product, reduces the whole barrier propterty of product.

However, in the prior art, a customized mask scheme also exists, and overall 3D printing, CNC or injection molding is mostly adopted, so that data acquisition needs to be performed on a scanning wearer to acquire modeling data, a professional scanner needs to be used for acquisition or 360-degree shooting needs to be performed around the wearer, a general consumer lacks necessary equipment or environmental conditions, and modeling data acquisition needs to be performed under the guidance of technicians in the field, so that the data acquisition efficiency is poor. For example, the Chinese patent (application No. 201910708483.3) discloses a method for manufacturing a customized mask support, wherein 6-15 photos or a video is required for collecting face modeling data, and the collection steps are complicated; in some schemes, a scanner is used as a collection end to collect data, and a scanner needs to be added every time a collection terminal is added, so that the hardware cost is high, and meanwhile, a collector needs to go to a specific position to collect data. In summary, the current collection method is difficult to be applied to general consumers, and the collection efficiency is poor, so that the current collection method is difficult to be applied to large-scale commercial application.

Meanwhile, in the prior art, in order to match with facial features of a wearer, customized parts are more, consumables are increased, manufacturing cost is high, and comfort is difficult to guarantee. Chinese patent (application number: 201710224123.7) discloses a customized mask and a preparation method thereof, the preparation method is a 3D printing integrated structure, although the mask can be matched with the face of a wearer, the integrated structure causes higher printing cost, and meanwhile, the comfort degree of the 3D printing part is difficult to ensure because the 3D printing part is directly attached to the skin.

In conclusion, how to improve the modeling data acquisition efficiency of the wearer of the customized mask, realize low-cost manufacture, improve the sealing performance of the mask and improve the comfort of the wearer is an important technical problem to be solved by technical personnel in the field at present.
