Description

Modular mask convenient to combine

Technical Field

The invention belongs to the technical field of masks, and particularly relates to a modular mask convenient to combine.

Background

Along with the development of the Chinese industry, the pollution emission is increased, and the air quality is deteriorated in recent years. As more and more people become sick from air pollution, the public is also increasingly concerned about air quality. Meanwhile, the mask has a certain protection effect on air pollution, and the use requirement is higher and higher, so that the mask cannot be ignored. However, the existing masks still have some problems.

First, although current gauze mask has certain safeguard effect, the user experience when wearing is extremely not good, and current gauze mask will make cloth gas permeability not good because of will playing the guard action. At present, when most of masks on the market are used for breathing, gas escapes from the upper part of the mask, which can seriously affect the sight, and particularly, the glasses of people wearing glasses can be fogged and are severe

Heavy time can cause safety issues.

Secondly, the gas discharged by a person during breathing does not contain gases such as carbon dioxide, and also contains water vapor and bacteria, which do not escape like the gases such as carbon dioxide and remain on the mask. The moisture response of the inner side of the mask is improved after the mask is worn for a long time, and discomfort and even allergy are brought to people. Moreover, water vapor remains in the mask, which is more likely to breed bacteria and cause health problems. The filter replaceable masks on the market still do not effectively solve these problems.

Finally, most of the existing masks are disposable masks which are thrown away when used, and resources are wasted disadvantageously

In view of the sustainable development, it is necessary to improve the breathing smoothness of the mask, so that the mask breathes more smoothly, safely and environmentally.

Detailed Description

The invention is described in further detail below with reference to the accompanying drawings, and specific embodiments are given.

As shown in fig. 1 to 4, the mask of the present invention is a modular mask that is convenient to assemble, and changes the integral structure of the conventional mask, and the modular connection is realized by the upper piece, the middle piece, the lower piece and the base with the shape of wide upper part and narrow lower part. In order to realize the fit between the mask and the face when the mask is worn, an aluminum strip is bonded on the upper piece, the upper edge of the upper piece is positioned on the upper side of the bridge of the nose of a human body, the aluminum strip is positioned at the position of the upper piece corresponding to the bridge of the nose, and the aluminum strip can be bent at will and can be adjusted according to the shape of the bridge of the nose of a wearer; the middle piece is provided with a filter opening in a bonding mode, the filter opening is opposite to the nose of a human body, filter materials are arranged in the filter opening, the structure of the filter opening in the intelligent mask in the prior art can be adopted as the structure of the filter opening, the specific structure of the filter opening is not described in detail, the filter materials in the filter opening can block harmful substances in the air, the protection performance is improved, the upper end and the lower end of the middle piece respectively extend to the inner side of the lower edge of the upper piece and the inner side of the upper edge of the lower piece, and the base is provided with lugs.

Preferably, the upper piece, the middle piece, the lower piece and the base are detachably connected through a snap fastener assembly, the snap fastener assembly comprises a first female fastener, a second female fastener, a third female fastener, a fourth female fastener, a first male fastener, a second male fastener, a third male fastener and a fourth male fastener, the first female fastener and the second female fastener are respectively connected with the first female fastener, the second female fastener, the third female fastener and the fourth female fastener, the first male fastener and the second male fastener are arranged on the upper piece, the first male fastener is correspondingly arranged on the base, and the second male fastener is correspondingly arranged at the upper end of the lower piece; the third box sets up on the well piece, and base correspondence position department sets up the third pin thread, and the fourth box setting is on lower piece, and the fourth box is located the outside of second pin thread, and the fourth pin thread corresponds the setting on the base.

The invention realizes the opening and closing of the mask by the principle of the difference between the internal air pressure and the external air pressure. When a user inhales air, the air pressure on the inner side of the mask is reduced, the cloth is attached to the face more tightly, and air can only enter the inner side through the filter opening; when a user exhales, the air pressure on the inner side of the mask is increased, the gap between the middle piece and the upper piece and the gap between the middle piece and the lower piece are opened, and air rapidly escapes from the gap instead of the upper side of the mask. Thereby the problem that the breathing is inconvenient after the common mask is worn, and moisture is remained in the mask to easily generate bacteria is solved.

When using the gauze mask, at first the user can select the cloth that corresponds colour and material according to the demand of oneself, then carries out fast assembly through snap-fastener subassembly, wears after the equipment is accomplished, because most gas includes that vapor and bacterium all follow the gap between the gauze mask and escape, the user wears for a long time still can not feel uncomfortable, and bacterial growing is few, and breathes very naturally, and differs few when not wearing the gauze mask, and is very comfortable.
