Abstract

A smog or dustproofing 3D mask wearable device, comprising a wearable device fitting surface (1), wherein a circular supporting cavity (3) is formed in the inner wall of the wearable device fitting surface (1); the opening direction of the supporting cavity (1) faces the inner side of the circle of the wearable device fitting surface (1); a nose wing groove (2) is formed in the wearable device fitting surface (1). The present smog mask wearable device may allow the filtering efficiency of all disposable 3D masks on the market to completely reach standard when used. The smog mask wearable device has a low price, is economically suitable and convenient to use, and original 3D masks do not need to be done away with and improved. The device is reusable, low in carbon, environmentally-friendly, and low in price, and is thus affordable to low-income workers. The present smog mask wearable device is suitable for public consumption and practical.

Description

Haze or dust-proof 3D mask wearer

Cross-reference to related applications

This application claims priority from a Chinese patent application filed with the Chinese Patent Office on September 12, 2018 under the application number CN2018214862515 and entitled "A Haze or Dust 3D Mask Wearer", the entire contents of which are incorporated herein by reference. In this application.

Technical field

The present application relates to the technical field of daily necessities, and in particular to a haze or dust-proof 3D mask wearer.

Background technique

At present, the filtration efficiency of disposable 3D masks produced by most regular manufacturers on the market can reach the standard (more than 90% filtration efficiency), but most of the masks on the market because of their special materials, so masks and The tightness of the face is particularly poor, especially at the bridge of the nose. Although the bridge of the nose is used, the shape of the mask at the bridge of the nose can be adjusted when wearing, but that is because the air leakage in that place is the worst, especially for those wearing glasses. So now most of the masks on the market can meet the filtering efficiency, but the filtering efficiency is greatly reduced when people use it. The main reason is that the tightness between the mask and the face is poor. Therefore, we propose a haze or dust-proof 3D mask. Wearer.

Summary of the Invention

The purpose of this application is to provide a haze or dust-proof 3D mask wearer to solve the problems raised in the background art described above.

In order to achieve the above object, the present application provides the following technical solution: A haze or dust-proof 3D mask wearer includes a wearer fitting surface and a sticking surface, and an inner wall of the wearer fitting surface is provided with a circle of supporting cavity. In addition, the opening direction of the support cavity faces the inside of the circle of the wearing surface of the wearer, the sticking surface is located on the side of the wearing surface of the wearing surface, and a nose groove is formed on the wearing surface of the wearing surface.

Further, the fitting surface, the sticking surface and the nose groove of the wearer are integrally formed, and the material is made of silicone.

Further, the width of the pasting surface is 1 cm.

Further, the surface of the pasting surface is coated with an adhesive layer.

Further, the shape of the attachment surface and the attachment surface of the wearer is circular or semicircular.

Compared with the prior art, the beneficial effects of this application are:

1. The haze mask wearer can be used with all disposable 3D masks in the market, so that all disposable 3D masks in the market can meet the filtering efficiency standards when used, and the price is cheap and economical, convenient to use, and does not need to damage the original mask. And improved, can be reused, low-carbon and environmentally friendly, and at the same time wear the device on the nose and mouth, which has the effect of airtightness;

2. The haze mask wearer is cheaper than high port masks with filters or fans on the market, and can be used by low-income and working-class workers. The haze mask wearer is suitable for mass consumption and has practicality.

detailed description

In the following, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

Please refer to FIG. 1. This application provides a technical solution. Embodiment 1: A haze or dust-proof 3D mask wearer includes a wearer fitting surface 1, and an inner wall of the wearer fitting surface 1 is opened in a circle for support. The cavity 3, and the opening direction of the supporting cavity 3 faces the inside of the circle of the wearing surface 1 of the wearer. A nose groove 2 is opened on the wearing surface 1 of the wearer. The mask wearer is an integrated silicone wearer. , Haze or dust-proof 3D masks are most likely to cause air leakage during use. The place where the effect is poor is that the combination of the mask on the nose and the face is quite poor. The joint between the mask and the face chin is still quite tight, so The wearer can also be made into an upper half-section type, that is, Embodiment 2, as shown in FIG. 2.

Among them, the lower surface of the wearing surface 1 is provided with an adhesive surface 4 and the width of the adhesive surface is 1 cm. By applying adhesive on the adhesive surface, the mask is adhered to the adhesive surface 4. After repeated use, the mask needs When discarding, just tear off the mask from the adhesive surface 4 and replace it with a new one. If the adhesive surface 4 is not too sticky, put the adhesive surface 4 into the water and rinse it repeatedly. Paste and use again.

Working principle: Apply adhesive on the adhesive surface 4 of the wearer to make the mask fit the adhesive surface 4, and then adjust the shape of the wearer's adhesive surface 1 to the face so that the face is tightly combined. When the mask can no longer filter the haze, just tear the mask from the adhesive surface 4 and replace it with a new one.

Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, and replacements can be made to these embodiments without departing from the principle and spirit of the present application. And variations, the scope of the application is defined by the appended claims and their equivalents.
