Detailed Description

The present invention will be further explained with reference to the accompanying drawings and embodiments:

referring to fig. 1-8, the present invention discloses a mask, which comprises a frame and a transparent mask 10, wherein the frame has an arch structure enclosed to the inner side, the arch structure has an inner cavity for shielding the face of a human body, the arch structure is composed of a boss 11 located at the upper end of the frame, a horizontal platform 12 located at the lower end of the frame, an outer connecting frame 13 and an inner connecting frame 14 for connecting the boss 11 and the horizontal platform 12, the transparent mask 10 is hinged to the outer connecting frame 13 through a mounting frame 15, and an air bag 16 is arranged at the inner side of the inner connecting frame 14.

The outer connecting frame 13 is symmetrically arranged on the same side of the boss 11 and the horizontal table 12, the top end of the mounting frame 15 is hinged on the boss 11, magnets are arranged in the two vertical frame strips 17 of the mounting frame 15, and the two vertical frame strips 17 are attracted with the outer connecting frame 13. The installation frame 15 of the transparent mask 10 is installed in a hinged mode, so that the use is convenient, the transparent mask 10 is opened and closed in a magnet attraction mode, and the sealing performance is convenient, quick and good.

As shown in figure 4, the tail end of the inner connecting frame 14 is obliquely arranged between the boss 11 and the horizontal platform 12 towards the direction of the outer connecting frame 13, so that the mask is in a structural shape with a large top and a small bottom, namely, one end of the boss 11 close to the air bag 16 is protruded relative to the horizontal platform 12, therefore, when the mask is used, the boss 11 can be mostly pressed on the head of a human body, and the mask is not easy to fall off.

The end of the horizontal platform 12 connected with the inner sleeve connecting frame 14 is provided with an arc 18 arched towards one side of the transparent face mask 10, and the arc 18 is used for supporting the chin of a human body, so that the face mask is attached to the head of the human body and is more comfortable to wear.

The inner side of the outer side of the air bag 16 is provided with a non-stretchable flexible material layer 19 in a sticking mode, the material of the flexible material layer 19 is polymer material such as resin, fiber or rubber, an inflation inlet and a deflation inlet are arranged on the front side surface of the air bag 16, the flexible material layer 19 only increases the thickness of the air bag 16 when the air bag 16 is inflated and does not stretch in length, so that the shape of the air bag 16 is matched with the inner wall of the inner sleeve connecting frame 14 and is kept. When the air bag is used, the air bag 16 is inflated by connecting the air source with the inflation port, and when the pressure in the air bag 16 does not exceed the pressure before the air bag reaches rigidity, the power supply of the air source is turned off, so that the air bag 16 keeps flexibility; to prevent the balloon 16 from bursting when the pressure within the balloon 16 exceeds a preset limit, deflation is performed through a deflation port. The air pressure of the air bag 16 is adjusted by personnel, so that the air bag 16 is fully attached to the inner wall of the inner sleeve connecting frame 14, the air bag can adapt to different human head types while the sealing performance is ensured, and the wearing comfort degree is ensured.

The boss 11 is provided with a through hole 20, a miniature electric fan 21 is arranged in the through hole 20, the top end of the through hole 20 is covered with a top filter layer 22, and a protective shell 23 is arranged above the top filter layer 22. The middle part of the horizontal platform 12 is a cavity, and a bottom exhaust filter layer 24 is arranged in the cavity. The top filter layer 22 and the bottom exhaust filter layer 24 are used for filtering dust droplets and ensuring the health of the respiratory tract of a human body.

A transparent side cover 25 is arranged between the outer connecting frame 13 and the inner connecting frame 14.

Of course, the above illustration is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, so all equivalent changes made in the principle of the present invention should be included in the protection scope of the present invention.
