Description

Novel mask

Technical Field

The utility model relates to the technical field of masks, in particular to a novel mask.

Background

The mask is a protective article worn on the mouth and nose to filter air entering the nose, and particularly, the mask becomes a necessary article for daily wearing of people since the global outbreak of novel coronavirus.

The existing mask is mostly made by laminating fabrics such as gauze, non-woven fabrics, melt-blown fabrics and the like. The air is filtered by the fabric layer and then inhaled into the human body, but simultaneously, the gas and the water vapor exhaled by the human body are blocked at the inner side of the mask, the air permeability of the fabric layer is reduced in the long term, and the respiratory resistance is increased; and the mask is easy to breed bacteria and is inhaled again by users, so that the protection function of the mask is weakened. In addition, the edge of the mask is difficult to continuously keep tightly attached to the face of a user, and the gaps around the mask greatly reduce the protection effect; the mask fabric has a large area, almost covers the whole face of a user, and also influences the visual aesthetic feeling of people; moreover, most of the existing masks are disposable, so that the consumption is extremely high, resources are wasted, and the environment is polluted.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a novel mask, which effectively solves the technical problems that the exhaled air and the water vapor of the existing mask are blocked at the inner side of the mask, and solves the technical problems that gaps exist around the existing mask, the fabric area of the mask is large, and the like.

In order to achieve the purpose, the specific scheme is as follows:

a novel mask comprises a mask main body, a mask surface body, a valve and an air purifying substance; the mask main body comprises an air valve part, an inspiration pipeline and an expiration pipeline; the air valve part comprises a one-way inhalation valve and a one-way exhalation valve; the mask surface body comprises a mask body and a surface cover; when the user breathes, the one-way inhalation valve and the one-way exhalation valve are both in a closed state, when the user breathes, the one-way inhalation valve is opened, the one-way exhalation valve is closed, and when the user breathes, the one-way exhalation valve is opened, and the one-way inhalation valve is closed.

Furthermore, the valve is a plastic sheet or an elastic steel sheet.

Further, the air purifier is filled in the air suction pipeline.

Further, the mask body is a mask covering the nose and the mouth.

Further, the mask body is a nose mask which only covers the nose.

Furthermore, convex edges are arranged around the inner side of the cover body.

Furthermore, the mask surface body and/or the mask main body are made of transparent plastic materials or transparent silica gel materials.

Furthermore, the user inhales the filtered fresh air through the inhalation pipeline, and exhales the exhaled air and water vapor directly out of the mask through the exhalation pipeline without obstruction.

The utility model has the beneficial effects that: through the setting of two one-way pneumatic valve of door, the user inhales filterable fresh air through the pipeline of breathing in on one side, directly discharges the breathing out gas and vapor outside the gauze mask without the separation through exhaling the pipeline on one side. Furthermore, the protection effect and the visual aesthetic feeling of the mask are improved; the reuse rate of the mask is improved, and the mask is more energy-saving and environment-friendly.

Detailed Description

As shown in fig. 1 and 2, the novel mask comprises a mask body 1, a mask body 2, a valve 3 and an air purifying material 4.

The mask body 1 is provided with a gas valve portion 11, an inhalation duct 12 and an exhalation duct 13.

The air valve part 11 is of an inverted T-shaped three-way structure, and the middle upper part is a breathing airway directly communicated with the breathing part of a user; the two sides are respectively an inspiration pipeline 12 and an expiration pipeline 13 which are communicated with the outside through the valve 3; the one-way inhalation valve 112 is arranged at the side of the inhalation pipeline 12, and the one-way exhalation valve 113 is arranged at the side of the exhalation pipeline 13. The one-way air valve is normally closed and can be opened by the respiratory airflow of a user. When the user does not breathe, the one-way inhalation valve 112 and the one-way exhalation valve 113 are both in a closed state; when a user inhales, the one-way inhalation valve 112 is opened, the one-way exhalation valve 113 is closed, and purified fresh air is inhaled through the inhalation pipeline 12; when a user exhales, the one-way exhalation valve 113 is opened and the one-way inhalation valve 112 is closed, and exhaled gas and water vapor are directly exhausted out of the mask through the exhalation pipeline 13 without being blocked.

The two valves 3 of the embodiment adopt U-shaped plastic sheets with two doors integrated, and thin U-shaped elastic steel sheets can be selected; the structure is simple and practical. In addition, the valve 3 also includes a combination structure (not shown in detail) using a rotary hinge and a torsion spring.

The air purifying material 4 is filled in the air intake duct 12. The air purifying material 4 can be any combination of a melt-blown non-woven fabric layer, a alginate fiber filtering layer, a nano silver antibacterial layer, a graphene oxide functional filtering layer, an activated carbon layer and the like; or herba Menthae sachet, negative oxygen ion gas permeable substance, etc. In addition, the end of the suction pipe 12 may be provided with an interface to additionally receive a small air cleaner.

The mask body 2 includes a mask body 21 and face covers 22 on both sides of the mask body 21. The mask body 21 is used for covering the breathing parts of the nose, mouth and the like of a user to isolate the breathing parts from the outside; the face cover 22 is used to sew the opening faces of the inhalation tube 12 and the exhalation tube 13 on both sides of the mask body 1.

As shown in fig. 3, the inner side of the cover 21 is also provided with a convex edge 211 of silica gel or foam that fits the contour of a human face, so as to continuously keep close contact with the face of a user and eliminate the gaps around.

Because people usually breathe through the nose and mouth only under special conditions, the mask can be divided into two mask bodies 21 according to the human face of the user, one mask 21b only covering the nose and the other mask 21m simultaneously covering the nose and the mouth. The face mask 21m may be an integral one, or may be a combination of a mouth mask 21k which covers only the mouth and is fitted under the nose mask 21 b. The embedding combination mode can adopt a pin-column structure in interference fit for pressing. As shown in fig. 4.

In this embodiment, the ear hook 18 for wearing the mask is integrally formed with the breathing/inhaling pipe of the mask body 1. In addition, a magic tape can be welded outside the breathing/inhaling pipeline and is butted with the head (back neck) through the magic tape; an ear hook or a rope for wearing can be additionally arranged (a specific drawing is not shown) like the existing mask.

Mask face body 2 and mask main part 1 be equipped with tip post 14 and tip hole 24 respectively, carry out the pressfitting with mask face body 2 and mask main part 1 through filling up complex tip post structure, or adopt the magic subsides to bond. The movable combination of pressing or bonding is convenient for replacing the air purifying object 4 and the valve 3 and cleaning, and is more beneficial to the reuse of the novel mask.

The mask body 2 and the mask body 1 can be fixedly combined by adopting a welding mode.

As shown in fig. 5, a nose bridge clip 23 is used instead of the ear clip 18 in a novel mask of a mask body 21b of a nose mask type, and the nose bridge clip 23 is a metal sheet which can be bent arbitrarily.

The mask body 1 and the mask body 2 can be made of transparent silica gel materials or transparent plastic materials, and can be customized according to the complexion of the face of a user, so that the visual aesthetic feeling is improved.

The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the above embodiments; the protection scope of the present invention should be determined by the following claims as long as they achieve the technical effects of the present invention by any means.
