Description

Technical Field

[0001] The invention relates to a mask, in particular to a close-fitting mask. Background Art

[0002] Existing masks generally have the following three problems:

[0003] 1. When wearing an ordinary mask, the amount of air retained in the mask is large. Each time you inhale air, you must first inhale a part of the waste gas exhaled last time and retained in the mask. Assuming that each person breathes 20 times per minute and the amount of air retained in the mask is 20 ml, each person inhales a total of 576 liters of waste gas in 24 hours.

[0004] 2. When ordinary masks are worn, although there is a nose clip for shaping, as people move their faces such as talking and yawning, the shaping strip will be deformed and the fit will deteriorate, thereby reducing the air filtering ability of the mask. In addition, many people forget to use the shaping function of the nose clip, which makes the actual sealing effect of the mask worse and the mask loses its air filtering function.

[0005] 3. When wearing an ordinary mask, if the person's head is in an upright position, the hot air exhaled by the person will drift upwards during the rising process after passing through the mask. Some of the hot air will make the eyes feel hot and suffocating. If wearing glasses, when the ambient temperature is low (below about 20℃), the water mist in the hot air will condense on the lenses. It is difficult for ordinary masks to solve the above-mentioned problems of hot air causing hot eyes and water mist in the hot air condensing on the lenses of glasses, causing blurred vision and other safety hazards, such as affecting vehicle driving or surgical operations. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a close-fitting mask in view of the deficiencies in the prior art.

[0007] The technical solution adopted by the present invention to solve its technical problems is: a close-fitting mask, characterized in that it includes a first mask body, a support layer and a first mask layer, the support layer is located between the first mask body and the first mask layer, the support layer includes a π-type inverted support frame and a fitting frame, the π-type inverted support frame is close to the inner side of the first mask layer, and the fitting frame is close to the outer side of the first mask body.

[0008] The sides A, B and C of the first mask body are respectively connected to the sides a, b and c of the first mask layer by bonding or sewing, and the first mask layer is provided with first transverse folds.

[0009] The π-type inverted support frame is an inverted π-type frame, and the bonding frame is two vertical bars connected to the two feet of the π-type inverted support frame. The two feet of the π-type inverted support frame and the two vertical bars of the bonding frame can be connected by integral manufacturing, pasting or sewing.

[0010] The support layer is an elastic sheet, and the π-type inverted support frame and the fitting frame have a certain opening angle, and the opening angle is 30 to 70 degrees. The π-type inverted support frame is used to open the first mask layer, and the fitting frame is used to press the outer side of the first mask body so that the inner side of the first mask body fits on the face on both sides of the nose.

[0011] The length of the side e of the π-type flip-chip support frame is less than or equal to the side d of the first mask layer, and the height f of the support layer is less than or equal to the side a of the first mask layer.

[0012] The π-shaped inverted support frame is fixed to the inner side of the first mask layer by gluing or sewing.

[0013] A close-fitting mask, characterized in that it comprises a second mask body and a second mask layer, a plurality of shaping strips are sequentially arranged on the bridge of the nose outside the second mask body, edges D, E and F of the second mask body are respectively fixed to edges g, h and i of the mask layer, a second transverse fold is arranged on the outer side of the second mask layer, and an elastic sheet is arranged on the bottom of the second mask layer.

[0014] The elastic support strip is a straight elastic sheet, and the length of the elastic support strip is less than or equal to the side h.

[0015] The beneficial effects of the present invention are:

[0016] (1) By setting up a support layer or increasing the number of molding strips, the amount of waste gas retained in the mask can be reduced, and the amount of waste gas inhaled can be reduced;

[0017] (2) By setting a support layer or increasing the number of shaping strips, the fit between the mask and the face is improved and the sealing effect is enhanced;

DETAILED DESCRIPTION

[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention application are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0026] Embodiment 1

[0027] like Figure 1 , 2 As shown, a close-fitting mask is characterized in that it includes a first mask body (1), a support layer (2) and a first mask layer (3), wherein the support layer (2) is located between the first mask body (1) and the first mask layer (3), and the support layer (2) includes a π-type inverted support frame (14) and a fitting frame (7), wherein the π-type inverted support frame (14) is close to the inner side of the first mask layer (3), and the fitting frame (7) is close to the outer side of the first mask body (1).

[0028] The side A (4), side B (5) and side C (6) of the first mask body (1) are respectively bonded or sewn to the side a (13), side b (9) and side c (11) of the first mask layer (3), and the first mask layer (3) is provided with a first transverse fold (10).

[0029] The length of the side e (15) of the π-type flip-chip support frame (14) is less than or equal to the side d (12) of the first mask layer (3), and the height f (8) of the support layer (2) is less than or equal to the side a (13) of the first mask layer (3).

[0030] The π-shaped inverted support frame (14) is fixed to the inner side of the first mask layer (3) by gluing or sewing.

[0031] Preferably, Figure 3 As shown, the π-type inverted support frame (14) is an inverted π-type frame, and the bonding frame (7) is two vertical bars connected to the two legs of the π-type inverted support frame (14). The π-type inverted support frame (14) and the bonding frame (7) can be manufactured in one piece.

[0032] The support layer (2) is an elastic sheet, and the π-shaped inverted support frame (14) and the fitting frame (7) have a certain opening angle, and the opening angle is 30 to 70 degrees. The π-shaped inverted support frame (14) is used to open the first mask layer (3), and the fitting frame (7) is used to press the outer side of the first mask body (1) so that the inner side of the first mask body (1) fits the face on both sides of the nose.

[0033] Specifically, the inner side of the first mask body (1) is the side in contact with the human face, the outer side of the first mask body (1) is the side in contact with the fitting frame (7), the inner side of the first mask layer (3) is the side connected to the π-type inverted support frame (14), and the outer side of the first mask layer (3) is the side exposed to the air.

[0034] The opening angle of the π-shaped inverted support frame (14) and the fitting frame (7) folded under the π-shaped inverted support frame in a natural state is 30-70°, which is based on the fact that the nasal angle of the nose of the human face is generally 30-33°. The opening angle should be greater than or equal to the minimum angle of the nasal angle, so the opening angle is 30-70°. When in use, the appropriate opening angle can be manually adjusted to make wearing more comfortable.

[0035] When in use, because the support layer (2) has a large elastic effect, the fitting frame (7) of the support layer (2) is pressed so that the first mask body (1) below the fitting frame (7) fits tightly to the face on both sides of the nose. The existing masks are always convex in this part. After the fitting frame (7) of the present invention is close to the face, this part is concave inward, so that the air retention in the mask is greatly reduced. At the same time, the sealing performance of the mask is also enhanced. When breathing, the amount of waste gas inhaled from the last exhalation is greatly reduced. In addition, the effect of the molding strip on the upper part of the general mask becomes worse due to changes in facial movements. However, the unique structure of the support layer of the present invention can be adaptively adjusted during use, so that the fitting frame is always kept in close contact with the face, and the sealing performance of the mask is guaranteed. In addition, the π-type inverted support frame (14) supports the first mask layer (3), and the first mask layer (3) bulges outward to form a semi-enclosed space with an opening downward. If a person's head is in an upright position, the hot air passing through the first mask body (1) will be blocked by the first mask layer (3) during the rising process, and will be kept away from the eyes of the person, so that the person will not feel the heat in the eyes. If the person wears glasses, the phenomenon of water mist condensing on the glasses lenses caused by the hot air exhaled by the person will be greatly reduced.

[0036] Embodiment 2

[0037] like Figure 4 As shown, based on the first embodiment, the two legs of the π-shaped inverted support frame (14) are connected to the two vertical strips of the bonding frame (7) by sewing or gluing.

[0038] The support layer (2) is an elastic sheet, and the π-shaped inverted support frame (14) and the fitting frame (7) have a certain opening angle, and the opening angle is 30 to 70 degrees. The π-shaped inverted support frame (14) is used to open the first mask layer (3), and the fitting frame (7) is used to press the outer side of the first mask body (1) so that the inner side of the first mask body (1) fits the face on both sides of the nose.

[0039] Embodiment 3

[0040] like Figure 5 As shown, a close-fitting mask is characterized in that it includes a second mask body (16) and a second mask layer (17), a plurality of shaping strips (25) are sequentially arranged at the nose bridge position outside the second mask body (16), the side D (18), side E (19), and side F (20) of the second mask body (16) are respectively glued or sewn to the side g (21), side h (22), and side i (23) of the second mask layer (17), the second mask layer (17) is provided with a transverse second fold (26) on the outside, and an elastic sheet (24) is provided at the bottom of the second mask layer (17).

[0041] The elastic support strip (24) is a straight elastic thin sheet, and the length of the elastic support strip (24) is less than or equal to the side h (22).

[0042] The inner side of the second mask body (16) is the side in contact with the human face, the outer side of the second mask body (16) is close to the second mask layer (17), and the outer side of the second mask layer (17) is the side exposed to the air.

[0043] When in use, the plurality of shaping strips (25) on the second mask body (16) are pressed simultaneously to shape the main body of the mask according to the bridge of the nose and the sides of the nose, so that the amount of air retention in the mask is greatly reduced, and at the same time, the sealing performance of the mask is also enhanced. When breathing, the amount of waste gas inhaled from the last exhalation is greatly reduced; in addition, when worn, the elastic sheet (24) causes the lower edge of the second mask layer (17) to form an outwardly protruding profile, and at the same time, by adjusting the second folds (26), the second mask layer (17) is protruded outward to form a semi-enclosed space with an opening downward. If a person's head is in an upright state, the hot air exhaled by the person will be blocked by the mask layer during the rising process, away from the person's eyes, and will not give the person a feeling of hot smoke in the eyes. If glasses are worn, the phenomenon of water mist condensing on the glasses lenses caused by the hot air exhaled by the person will be greatly reduced.

[0044] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
