Abstract

The invention discloses a mask produced through the 3D printing technology. The mask is composed of a mask body (1) and a fixing device (2). The fixing device (2) of the mask is connected with the mask body (1) to form an integral mask. The mask is characterized in that the shape of the mask body (1) and/or the fixing device (2) is matched with the facial contour based on the facial outline characteristics and is printed through a 3D printer. A digital model of the mask can be designed in an individualized mode under the condition that the requirements for the facial outline adaptability, comfort and functional performance are met.

Description

The mouth mask that 3D technology is produced

Technical field

The present invention relates to a kind of mouth mask of printing by 3D technology, especially a kind ofly adapt with face contour face, the mouth mask of comfortable and satisfying personalized, multi-functional demand.

Background technology

Along with China's economic development, environmental disruption, the environment events such as sandstorm, haze are day by day frequent.According to environmental administration's recent statistics, at present, some metropolitan gray haze number of days of China, have reached annual more than 30%, and what have even reaches annual half left and right.On April 2nd, 2013, New York Times is said in report, according to the report of portion " global disease burden in 2010 assessment " by name, " environment particle contamination " become the fourth-largest lethal factor after diet risk, hypertension and smoking, and within 2010, China approximately has 1,200,000 people dead too early because open-air pollutes.Wearing mouth mask is that protection is the most effective means of environment particle contamination such as haze, sand and dust, vehicle exhaust.Meanwhile, prevent virus propagation, warming etc., also need to wear mouth mask.Mouth mask has become the necessity of people's life.

The data that provide according to China Textile commercial guild, within 2012, dust reduction capability mouth mask is 4.2 hundred million in the sales volume of industrial circle, and gas defence function mouth mask is 1,100 ten thousand in the sales volume of medical field.Because demand, the crowd of mouth mask are huge, various to the demand of mouth mask kind and function, also wear the day-to-day of mouth mask due to people, produce personalization, aesthetic requirement to mouth mask.

But the mouth mask of selling in the market can not meet people's demand.On August 6th, 2013, Shanghai City labour protection articles for use quality monitoring testing station, the critical index such as filter efficiency to sell on market 17 mouth masks, (always) slip, inspiratory resistance, expiratory resistance is tested.

Filter efficiency, is also that performance is killed in filterability, mouth mask filtration and the inhibition to the microorganism such as bacterium, virus of mouth mask to dust and particulate, refers to that, under the testing conditions of regulation, the percentage that mouth mask can filtering particle, is the basic index of mouth mask performance.Selective examination discovery, has the filter efficiency of 7 samples to be greater than 90%, and filter effect is better; 8 samples are lower than 50%, and minimum is only 6.5%.

The filter efficiency of mouth mask is high again, but wears closely sealed badly, and effective protection also cannot be provided, and therefore (always) slip of mouth mask, is also the closely sealed performance of mouth mask and people face, is a crucial technical indicator equally.Except 2 samples are because of undersized, cannot do outside this project testing, all the other 15 samples after testing, have 5 samples (always) slip to be less than 10%, and barrier propterty is better; 6 samples are greater than 50%.

The inspiratory resistance of mouth mask and expiratory resistance, can have influence on consumer's use impression.In 17 samples of this check, except 2 samples cannot do this project testing because of undersized, after testing, inspiratory resistance numerical value is not from 26 handkerchiefs to 274 handkerchiefs etc. for all the other 15 samples, from 21 handkerchiefs to 119 handkerchiefs not etc., the difference of various product is huge for expiratory resistance numerical value.

It is the one that increases material manufacturing technology that 3D prints, and it is a kind ofly to use powdery metal take mathematical model file as basis, and plastics, mineral, fiber etc. can jointing materials, carrys out the technology of constructed object by the mode of successively printing.3D printing technique have can to product carry out personalized customization, model modification cost little, not because article complexity increases cost, material is various, material can infinitely combine, can seamlessly print the advantage such as linkage function is more powerful.Compared with traditional mouth mask, 3D prints that mouth mask has mouth mask and face contour adaptation is better, and mouth mask slip is low, wears the features such as more comfortable.

Summary of the invention

The invention provides a kind of mouth mask, this mask main body (1) is printed printer by 3D and is printed, and can improve mouth mask and facial adaptation, greatly reduces mouth mask slip; Can improve user and wear impression, improve comfortable wearing; Can meet user individual and aesthetic requirement simultaneously.

In order to improve mouth mask and user face adaptability, the technical solution adopted for the present invention to solve the technical problems is: by the processing to user's one or more photo, user's face 3-D scanning, shooting or other approach are obtained to user's face three-dimensional feature; By 3 d modeling software, set up user's face three-dimensional digital model; By 3 d modeling software, user face threedimensional model and user's design or selected mouth mask model are compared, adjust mouth mask and design a model, until coincide with mask.

Wear impression in order to improve user, the technical solution adopted for the present invention to solve the technical problems is:

1. adjust mouth mask and design a model, until mouth mask profile and face contour adapt;

2. in mouth mask modelling, mask main body (1) designs the hole (hole) of certain area, reduce to improve mouth mask air-breathing and exhale;

3. the mouth mask facial part of fitting, can increase the comfortable precoat of face impression at mouth mask nexine.

In order to meet the demand of user to mouth mask functional diversities, the technical solution adopted for the present invention to solve the technical problems is: in the design of mouth mask threedimensional model, threedimensional model comprises the structure that can inlay, hang, paste or bind removable functional sheet (body).Functional sheet (body) can be activated-carbon filter sheet, nonwoven filter disc or other function filter discs.

In order to meet user individual and aesthetic requirement, the technical solution adopted for the present invention to solve the technical problems is:

1. guides user is used 3 d modeling software, sets up personalized mouth mask threedimensional model;

2. mouth mask basis three-dimensional digital model is provided, and guides user is carried out personalization creation on this basis.

Fixture (2) described in this patent refers to: extend out from the side of mask main body (1) portion, for mask main body (1) is fixed on to facial constructional device the mode such as to block, be.The technical scheme that this constructional device adopts is:

1. design: extend mask main body (1) both sides the cast that forms crotch shape or adapt with auricle based on auricle, suitable being hung on auricle by 3 d modeling software.And generate by 3D printer and common printing of mask main body (1);

2. can be directly by frenulum being, the mode such as stitching, hot rolling or stickup, be connected in mask main body (1) both sides, be to hang over after ear.Wherein tether material can be selected various bungees, nylon rope and other fabrics.

The invention has the beneficial effects as follows, can make mouth mask adapt with face contour better, comfortable wearing, diverse in function, and meet user individual needs.
