Problems solved by technology

[0003] 1. The matching between the mask and the human face is poor, and it is uncomfortable to wear. If worn for a long time, it is easy to form strangle marks locally;
[0004] 2. The matching between the mask and the human face is poor. When a person inhales, part of the air enters the inside of the mask from around the mask without being filtered, and then is inhaled into the human body;
[0005] 3. The matching between the mask and the human face is poor. When a person exhales, part of the gas is discharged from the mouth and nose through the upper side of the mask. At this time, if the person wearing the mask also wears glasses, it is easy to cause the glasses to be blurred;
[0006] 4. The exhalation and inhalation of the mask conflict, and the resistance is too large. Some people with poor cardiopulmonary function have difficulty using it

Embodiment 1

[0036] A kind of manufacturing method of the customized mask of the present embodiment comprises the following specific steps:

[0037] S10. Using a 3D scanner to perform three-dimensional scanning on the face of the human body to obtain scanning data;

[0038] S20, process the scan data obtained in step S10 and perform facial reverse modeling to obtain a facial model;

[0039] S30, according to the face model that obtains in the step S20, design the preliminary mask outline model;

[0040] S40. Add an interface matching the exhalation device and the inhalation device on the preliminary mask outline model obtained in step S30 to obtain the final mask outline model;

[0041] S50, by 3D printing the final mask outline model obtained in step S40 with a 3D printer, the mask outline model entity is obtained; the material of the mask outline model entity can be selected according to user needs, and is not specifically limited;

[0042] S60. Install an exhalation device, an inhalat...

Embodiment 2

[0046] This embodiment is a further improvement made on the basis of Embodiment 1. The specific differences between this embodiment and Embodiment 1 are:

[0047] What is further illustrated in this embodiment is that the specific operation steps of step S40 are as follows: add an interface that matches the exhalation device and the inhalation device on the preliminary mask outline model obtained in step S30, and then add the interface to the preliminary mask The contour model and the facial model obtained in step S20 are verified for matching degree. If the matching degree verification is up to standard, the final mask contour model is obtained. If the matching degree verification is not up to standard, then re-enter step S10. As for the degree of matching to meet the standard is a commercial secret, no specific explanation or limitation is made. For example, more than 90% is up to the standard, and less than 90% is up to the standard.

[0048] The exhalation device, inhalati...

Abstract

The invention belongs to a design method of a mask, and discloses a manufacturing method of a customized mask. The method comprises the following specific steps: S10, carrying out three-dimensional scanning on the face of a human body to obtain scanning data; S20, processing the scanning data and performing face reverse modeling to obtain a face model; S30, designing a preliminary mask contour model according to the face model; S40, adding interfaces matched with an expiration device and an inspiration device to the preliminary mask contour model to obtain a final mask contour model; S50, performing 3D printing on the final mask contour model to obtain a mask contour model entity; and S60, installing the expiration device, the inspiration device and a tightening belt at the interface of the mask contour model entity to obtain the final customized mask. The customized mask prepared by the preparation method is good in matching property with a human face and high in adaptation degree, and tightening marks are not easily formed locally after the mask is worn for a long time; and the breathing resistance and the inspiration resistance of the mask can be greatly reduced, and a wearer can breathe smoothly.

Description

technical field [0001] The invention belongs to a method for designing a mask, in particular to a method for making a customized mask. Background technique [0002] A mask is a protective device, mainly used to keep warm and / or filter the air to prevent cold air, dust, viruses, germs, etc. from being inhaled into the mouth and nose of the human body. The masks that people widely wear now have the following problems: [0003] 1. The matching between the mask and the human face is poor, and it is uncomfortable to wear. If worn for a long time, it is easy to form strangle marks locally; [0004] 2. The matching between the mask and the human face is poor. When a person inhales, part of the air enters the inside of the mask from around the mask without being filtered, and then is inhaled into the human body; [0005] 3. The matching between the mask and the human face is poor. When a person exhales, part of the gas is discharged from the mouth and nose through the upper side o...
