Preferably, the guide mechanism is an elastic inverted U-shaped guide strip with the transverse width larger than the width of the nose of the human body, and two sides of the elastic inverted U-shaped guide strip are connected through a soft connecting ring positioned on the degerming adsorption layer; the gas inlet and outlet structure comprises: the front end or the rear end of the bottom of the soft closed ring body is integrally connected with a light connecting sheet, and the light connecting sheet has the size as follows: when no external air flow exists, the light connecting sheet is positioned at the opposite end of the connecting end of the closed flexible ring body and just closes the bottom of the flexible closed ring body; and the bottom of the elastic inverted U-shaped guide strip is provided with a supporting hook capable of supporting the soft closed annular body.

As an improvement of the utility model, the upper clamping cover of the soft closed ring body is provided with a filtering cover body which can filter impurities and bacteria in the air.

As a further improvement of the present invention, the rear portions of the first annular connecting band and the second annular connecting band are integrally connected with two curved isolating bars, so that the rear portions of the first annular connecting band and the second annular connecting band are in an aerial ladder-shaped structure; meanwhile, the rear end of the first annular connecting belt is provided with a sticky buckle strip, and the rear end of the second annular connecting belt is provided with a sticky buckle strip which can form sticky buckle connection with the sticky buckle strip.

After the structure is adopted, the utility model has the advantages of as follows:

1. the utility model adopts a structure that the air can be discharged downwards when breathing out and can be automatically closed when breathing in, which can well prevent the exhaled turbid air from gathering in the mask and avoid discomfort for the wearer;

2. the utility model discloses can comparatively conveniently adjust the connection in the connection structure of ear according to everyone's facial size, can not connect in the ear but directly form with the brain rear portion and connect simultaneously, greatly improved the travelling comfort that the gauze mask was dressed.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As can be known from fig. 1 and fig. 2, a direction exhaust type mask comprises a mask body 1, a degerming adsorption layer 2 (such as adhesive connection) which is positioned in the mask body 1 and is detachably connected with the mask body 1, and a first annular connecting belt 3 and a second annular connecting belt 4 which are positioned on two sides of the mask body 1, a guide mechanism which can guide gas to the lower part when the nose part is discharged is detachably connected on the inner layer of the degerming adsorption layer 2, and a gas inlet and outlet structure which is opened when the nose part is discharged and closed when the nose part is sucked is arranged at the bottom of the guide mechanism.

The utility model discloses in, preferred guiding mechanism does: an elastic inverted U-shaped guide strip 5 with the transverse width larger than the width of the nose of a human body, wherein the two sides of the elastic inverted U-shaped guide strip 5 are connected through a soft connecting ring 6 positioned on the degerming adsorption layer.

In the present invention, the preferred gas inlet and outlet structure comprises: a soft closed ring body 7, the front end or the rear end integral type of the bottom of this soft closed ring body 7 is connected with light connection piece 8, in the utility model discloses in, the quantity of light connection piece 8 is two. The size of the light connecting sheet 8 is as follows: when no external air flow exists, the light connecting sheet 8 is positioned at the opposite end of the connecting end of the soft closed annular body 7 and just seals the bottom of the soft closed annular body 7; and a supporting hook 9 capable of supporting the soft closed annular body 7 is arranged at the bottom of the elastic inverted U-shaped guide strip 5. Meanwhile, a filter cover body 10 capable of filtering impurities and bacteria in the air is arranged on the upper end of the soft closed annular body 7 in a clamping manner.

When the nose exhales, gas can downwards reach the soft closed annular body 7 through the elastic inverted U-shaped guide strip 5, a filtering effect can be achieved when the gas passes through the filtering cover body 10, the gas continues downwards, the light connecting piece 8 is enabled to be impacted by the gas flow and opened, when the gas is inhaled, the light connecting piece 8 is closed, the inhaled gas is filtered once again through the filtering cover body 10, and the cleanness degree of the gas entering the mouth mask and the nasal cavity is guaranteed.
