Abstract

The invention provides a closing frame for improving closing performance of a respirator and a face mask. The closing frame comprises a closing surface 2 which is designed according to the face characteristics of special individual; the closing frame can be matched with and fit to the face; the closing frame is printed and produced through a 3D printer. The closing frame be used when wearing the respirator or the face mask and is able to reduce air leaking from the respirator and the face mask, and therefore, the closing performance of the respirator and the face mask can be improved.

Description

The closely sealed frame of mouth mask, face shield

Technical field

the present invention relates to the device that a kind of auxiliary mouth mask, face shield are closely sealed, especially one can make mouth mask, face shield fits tightly face, ensures the closely sealed frame of mouth mask, face shield adaptation.Closely sealed frame is printed by 3D printer and produces.。

Background technology

when generally wearing mouth mask, face shield; people the height of obtainable degree of protection; except the impact of mouth mask, the filtration of material effect of face shield own, structural design, environment for use, mouth mask, adaptation between face shield and wearer's face are important decisive factors., even if some mouth masks, mask designs have nose clip or sponge strip, still there is the situation of closely sealed tight, the air leakage of mouth mask, face shield and wearer's face in the mouth mask of current commercial type, face shield.Mouth mask, face shield adaptation are not enough mainly because mouth mask, visor shapes and size can not adapt to that the face contour of the people varied causes completely.

Summary of the invention

in order to overcome existing mouth mask, face shield adaptation is not enough, air leakage problem, the invention provides a kind of closely sealed frame improving mouth mask, face shield adaptation, this closely sealed frame is according to the face contour characteristic Design of particular person, and print production by 3D printer, consistent with wearer's face contour feature, reach the effect matching, fit.

in order to make the closely sealed frame 1 of mouth mask, face shield fit tightly face, the technical scheme of the technical problem that the present invention faces and employing is:

1, obtain particular individual face contour data: by the process to particular individual face one or more photo, particular individual face three-dimensional feature is obtained to the facial 3-D scanning of individuality or other approach;

2, extract the closed surface of closely sealed frame: according to the facial three-dimensional feature of above-mentioned acquisition, by 3 d modeling software, set up particular individual face three-dimensional digital model; According to the closed surface of the closely sealed frame of face contour feature extraction on facial mathematical model.Closed surface and face contour feature match, fit;

3, set up closely sealed frame mathematical model: based on closed surface mathematical model, prolong face contour face normal direction and increase certain thickness, design closely sealed frame mathematical model by 3 d modeling software.Closely sealed frame mathematical model is comprising on closed surface basis, can carry out other functional design;

4, closely sealed frame mathematical model is printed production by 3D printer.

Detailed description of the invention

describe below in conjunction with accompanying drawing:

embodiment 1, as shown in Figure 1 and Figure 2, in figure, 1 is a closely sealed frame 1.Its frame is at the face of people, and the closed surface 2 of closely sealed frame 1 is consistent with the face of people, matches, fits.The foundry goods cast just as mould and its is the same.Closed surface 2 is by the process to user one or more photo, obtains particular individual face three-dimensional feature to user's face 3-D scanning or other approach, by 3 d modeling software, sets up user's face three-dimensional digital model; The bridge of the nose is prolonged according to the closed surface 2(of the closely sealed frame of face contour feature extraction 1 in facial mathematical model basis namely, airtight curved surface that the wing of nose, cheek, lower jaw are formed to lip bottom).Closed surface 2 is annular.Set up on basis at closed surface 2, based on face shape profile, set up closely sealed frame 1 mathematical model comprising closed surface 2 by 3 d modeling software.Closely sealed frame 1 is printed by 3D printer.

embodiment 2, as shown in Figure 3, Figure 4, in figure, 3 is nose-bridge frame.Because part mouth mask, face shield product are only more serious in facial privileged sites gas leakage, as special case of the present invention, can refer to the technical scheme in embodiment 1, only according to the mathematical model of the closely sealed frame 3 of the characteristic Design of facial privileged sites, as only included the nose-bridge frame 3 of the bridge of the nose, wing of nose part.Printed by 3D printer.Because mouth mask, face shield mainly nose areas easily leak gas, nose-bridge frame 3 makes mouth mask, face shield match with position near the bridge of the nose and the wing of nose thereof, consistent, fit, thus avoid gas leakage.

embodiment 3, as shown in Fig. 5, Fig. 6, closely sealed frame 6 pairs of mouth masks, face shields are played a supporting role, and can be designed as the three-dimensional shape of certain space.Wearer can be met like this and breathe smooth and easy and comfortable needs.Closely sealed frame 6 can be hemispherical, half elliptic or other three-dimensional shapes, as the oxygen mask that pilot wears, and the shape such as all kinds of gas defence, dust-proof, chemical defence mask.

closely sealed frame 6 can have hole 5 to design.Hole 5 place of closely sealed frame 6 can be threaded or the device such as block/connect, and is convenient to and oxygen hose, and the device such as dust-proof, gas defence, the overanxious box of chemical defence connects.

the hole 5 of closely sealed frame 6 can also with mouth mask, face shield filtering bodies by bonding, be hang, block, the mode such as to buckle is connected use.Mouth mask, face shield filtering bodies are the sheet body structures with overanxious functions such as dust-proof, gas defence, chemical defences.Material is generally cloth, filter cotton, non-woven fabrics etc.

closely sealed frame 6 hole 5 can be opened at any position of closely sealed frame 6, and hole number, shape, size are not limit.

in embodiment 1-6; closely sealed frame is in order to reach the object making mouth mask, face shield and face closely sealed; closely sealed frame can be placed in mouth mask, between face shield and face, closely sealed frame is by pasting, be the structure of extension, buckle mouth mask, face shield, and with mouth mask, face shield cover body is seamless is connected; Closely sealed frame also can be placed in outside mouth mask, face shield, by connecting the pulling force effect of the fixtures such as the bandage of closely sealed frame, making mouth mask, face shield more press close to face, reaching closely sealed effect; Mouth mask, face shield also can be designed with insertion groove, and closely sealed frame directly can insert mouth mask, face shield insertion groove, coordinate mouth mask, mask body and face more closely sealed.

embodiment 4, as shown in Figure 7, closely sealed frame can directly connect frenulum 7, elastic cord, the fixtures such as buckle.Frenulum 7 etc. can directly with the perforate of closely sealed frame, or closely sealed frame upper process be, hanging hang structure 8 is connected, bind mutually.

the closely sealed frame of this mouth mask, face shield is directed to specific individual face, adopts state-of-the-art 3D printing technique, is printed produce by 3D printer.Its material of closely sealed frame described in above embodiment is all material that can be suitable for 3D printing.Can be, but not limited to: plastics, resin, plastic cement, silica gel, rubber, paper material, non-woven fabrics, metal and other.The match width, size, the shape that fit of the closed surface of closely sealed frame and face is not limit.Closely sealed frame integral outer character shape, size are not limit.
