In order to make the technical scheme of the present utility model better understood by those skilled in the art, the space ventilation type mask of the present utility model will be described in detail with reference to the accompanying drawings and the specific embodiments.

Referring to fig. 1 to 8, the present utility model provides a space ventilation mask, which comprises a veneering fixing layer 1, an inner filter layer 2, an intermediate filter layer 3, an outer filter layer 4, and the like, and is in an unfolded state (shown in fig. 9 and 12) when worn and in a folded state (shown in fig. 7 and 8) when initially stored.

The inner filter layer 2 and the middle filter layer 3 are provided with a section of connecting seam so as to form a folding part, the inner filter layer 2 and the middle filter layer 3 are of a two-layer structure, and the inner filter layer 2 and the middle filter layer 3 are contacted with each other in a folding state; it should be noted that, the inner layer filter layer 2 and the middle filter layer 3 may be formed by folding a piece of complete fabric to form a crease structure, or may be formed by fixing two pieces of mutually independent fabric through linear connection seams. In the drawings shown in the present utility model, the outer contour shape of the inner filter layer 2 and the outer contour shape of the intermediate filter layer 3 are identical, but the present utility model is not limited to this case, and the outer contour shape of the inner filter layer 2 and the outer contour shape of the intermediate filter layer 3 are identical only as a preferred embodiment, and different structural designs of the two contours can be adopted, and all specific structural forms shall be included in the protection scope of the present utility model.

It should be noted that the inner layer filter layer 2 and the middle filter layer 3 may be formed by folding the same piece of material, and at this time, the connection seam between the inner layer filter layer 2 and the middle filter layer 3 is formed by folding in half; the inner filter layer 2 and the middle filter layer 3 can also be respectively formed by processing two mutually independent material sheets, and are mutually connected in a sealing way at the connecting joint of the two, and the connecting joint can be linear or curved.

The two folding portions are disposed opposite to each other, and in this embodiment, the two folding portions are disposed axially symmetrically with respect to a vertical symmetry axis, and it should be noted that a structure in which the two folding portions are disposed symmetrically is only a preferred embodiment, and the scope of the present utility model is not limited thereto, and other layout forms may be adopted, such as a structure in which the two folding portions are disposed symmetrically with respect to a horizontal symmetry axis. In addition, in general, the two folded portions are ensured to be symmetrically distributed, but not necessarily, a structure in which the two folded portions are not completely symmetrical should be included, for example, for a structure in which an upper-lower layout is adopted, the shapes of the head portions at different positions are different, and the two folded portions can adopt different shapes. It is required that a connecting seam exists between the inner filter layer 2 and the middle filter layer 3 which form the symmetrical part to form a mutual doubling structure.

Because the connecting seam is arranged between the inner filter layer 2 and the middle filter layer 3 to form a mutual doubling-up area, a channel for gas circulation is arranged between the bending positions of the two doubling-up parts; when the inner filter layer 2 and the middle filter layer 3 are in folding contact with each other, the gap between the inner filter layer 2 and the middle filter layer 3 is small; when the mask is worn and unfolded, the gap between the inner layer filter layer 2 and the middle filter layer 3 is increased, the inner layer filter layer 2 and the middle filter layer 3 are provided with surfaces (outer surfaces) contacted with outside air, the other opposite surfaces face the face (inner surfaces), and the outside air enters the space between the mask and the face through the folded part formed by the inner layer filter layer 2 and the middle filter layer 3 for breathing by people.

At least part of the edges of the inner filter layer 2 and the veneering fixed layer 1 are relatively fixedly connected, and at least part of the edges of the middle filter layer 3 and the outer filter layer 4 are relatively fixedly connected; there is mutual fixed connection's relation between inlayer filter layer 2 and wainscot fixed layer 1, exists mutual fixed connection's relation between middle filter layer 3 and the outer filter layer 4, and the fifty percent discount portion that inlayer filter layer 2 and middle filter layer 3 formed is located wainscot fixed layer 1 and outer filter layer 4, is served as transitional coupling structure by the fifty percent discount portion. The inner filter layer 2 and the intermediate filter layer 3 are respectively connected to different structures among the facing fixing layer 1 and the outer filter layer 4.

Referring to fig. 3, the assembly mode of the space ventilation mask of the present utility model is shown, and two arrows are combined to show that the folded portion is folded in half from the plane unfolded state to form a folded state, and the inner filter layer 2 is fixedly connected with the veneering fixing layer 1 in the folded state, and the middle filter layer 3 is fixedly connected with the outer filter layer 4. In connection with fig. 3, dark edges are connected to each other, light edges are connected to each other, and the double-dashed arrows in the figure indicate the corresponding positions where the upper side edges are fixed in contact with each other, and the lower side edges are similar to this. Other connection points than the crease between the inner filter layer 2 and the intermediate filter layer 3 may not be provided, but a partially connected structure may be adopted, which will be described later.

The veneering fixing layer 1 is fixed on the inner layer filter layer 2, and the outer peripheral edge of the veneering fixing layer 1 and the outer peripheral edge of the inner layer filter layer 2 are generally mutually laminated and fixed; the veneering fixing layer 1 is in contact and lamination with the face, and is matched with the modeling of the face, and the veneering fixing layer 1 is used as a space between the face and the inner layer filtering layer 2.

As shown in fig. 9, 10 and 11, the space ventilation mask of the present utility model has a larger ventilation area, and the folded portion formed by the inner filter layer 2 and the middle filter layer 3 can allow air flow to pass through, and the outer filter layer 4 can allow air flow to pass through. The air passing through the outer layer filter layer 4 mainly flows along the front-back direction (along the direction of the face of the human body), and the air passing through the doubling-up part mainly flows along the lateral direction (up, down, left, right and oblique direction), compared with the traditional mask, the contact area between the inner layer filter layer 2 and the middle filter layer 3 and the outside air is further increased, the air flow is improved, and therefore the resistance of the air flow is reduced.

Based on the scheme, the utility model provides specific embodiments, and the folded parts formed by the inner layer filter layer 2 and the middle filter layer 3 are symmetrically distributed left and right and are folded inwards; inwardly folded means that, as seen from the front, neither the inner filter layer 2 nor the intermediate filter layer 3 exceeds the contour of the outer filter layer 4, and the folds of the two folded portions are close to each other.

As shown in fig. 7 and 8, the size of the mask in the left-right direction is larger than the size of the mask in the up-down direction, and the two folded portions in the present embodiment are symmetrically distributed in the left-right direction, so that the size of the inner filter layer 2 and the middle filter layer 3 in the left-right width direction are larger, and a larger ventilation area is formed for the air flow to pass through.

The inner filter layer 2 and/or the intermediate filter layer 3 are provided with organ-like fold areas. The organ-shaped folding area is not a plane structure and is provided with a plurality of folds formed by folding; the accordion fold has a greater surface area relative to the plane in an equal edge profile condition, thereby allowing more airflow to pass.

By defining the inner filter layer 2 and the intermediate filter layer 3 by providing spot-like joints, it is ensured that both the inner filter layer 2 and the intermediate filter layer 3 cannot be pulled apart substantially to form a mutually separated state. As shown in fig. 9, 10, and 11, the air flow can pass through the gaps between the inner filter layer 2 and the intermediate filter layer 3, which are not connected to each other. The veneering fixed layer 1, the inner filter layer 2 and the middle filter layer 3 are fixed together through the point-shaped joints, so that the integrity of the whole mask can be improved.

There is a gap between the two folded portions, via which the facing fixing layer 1 and the outer layer filter layer 4 are directly connected, i.e., there are some directly connected portions between the facing fixing layer 1 and the outer layer filter layer 4. As shown in fig. 3 and 4, the two folded parts formed by the inner filter layer 2 and the middle filter layer 3 are not tightly attached, and a channel is formed between the two folded parts, so that air flow passing through the outer filter layer 4 can pass through; the upper edge of the veneer fixing layer 1 and the upper edge of the outer layer filter layer 4 may be in direct contact through the passage between the two folded portions, and the lower edge of the veneer fixing layer 1 and the lower edge of the outer layer filter layer 4 may be in direct contact through the passage between the two folded portions, and there may be a portion where the upper and lower two sections of the veneer fixing layer 1 and the outer layer filter layer 4 are connected to each other. The veneering fixing layer 1 and the outer layer filtering layer 4 are directly connected at the passage between the two folding parts, which is helpful for improving the integrity of the mask.

The mask provided by the utility model further comprises the fixing band 5, the fixing band 5 is integrally fixed on the mask, and particularly, the fixing band 5 can be fixed at a point-shaped joint, and the fixing band 5, the fixing layer 1, the inner layer filtering layer 2 and the middle filtering layer 3 are relatively fixed during processing. The fixing strap 5 is used for fixing the mask on the head.

For the fixed band 5 adopting the hanging type, the fixed band 5 is used for hanging behind the ears, and the position of the fixed band 5 contacting with the ears is provided with a widening section, so that the pressure on the ears is reduced, and the wearing comfort is improved. Instead of a lug structure, the fixing strap 5 may also be fastened, i.e. behind the head.

With reference to fig. 3 and 4, the two veneering fixing layers 1 provided by the utility model are arranged in an up-down order, and the two veneering fixing layers 1 can respectively fix the two inner filter layers 2. The use of two separate facing layers 1 is a preferred embodiment to better match the facial contours, but the present utility model does not exclude the use of a one-piece integral annular structure of the facing layer 1.

In combination with fig. 5 and 6, the upper facing fixing layer 1 is provided with a nose bridge strip 6, and the nose bridge strip 6 can be plastically deformed, so that the nose bridge strip can be better attached to the nose.

The upper and lower veneering fixed layers 1 are in different shapes, the veneering fixed layer 1 positioned above is attached to the nose and the cheek, and the veneering fixed layer 1 positioned below is attached to the lower jaw.
