Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples.

Referring to fig. 1 and 2, an embodiment of the respiratory mask of the present invention mainly includes a support unit 10 and a soft mask unit 20. In addition, the support unit 10 can further cooperate with an air duct 30 and a pair of connecting members 40 for air transportation connection and convenient wearing and positioning, respectively, the air duct and the connecting members are not related to the features of the present invention, so that the detailed structure of the air duct and the connecting members will not be described in more detail below.

The supporting unit 10 is made of a hard plastic material, and includes a base 11 and a pair of wing frames 12 opposite to and fixedly connected to the base 11. The base 11 has a hollow ring-shaped disc portion 111 surrounding an axis L, and a sleeve portion 112 protruding from an inner circumferential edge of the disc portion 111. The wing frames 12 are respectively in an inverted L shape, and each of the wing frames has a connecting section 121 connected to the outer circumferential edge of the disc portion 111, a supporting section 122 connected to the connecting section 121 in an intersecting manner, and the supporting section 122 has a top edge 123 and a positioning portion 124 recessed in a concave hole shape due to the top edge 123. The top edge 123 is shaped like an arc, each of the top edges 123 has a connecting end 125 corresponding to the positioning portion 124 and a terminal end 126 opposite to the connecting end 125, and the connecting end 125 is gradually biased toward the base 11 when extending toward the terminal end 126.

The soft cover unit 20 is made of a flexible and deformable silicone material and is installed in the supporting unit 10, and includes a bottom wall 21 surrounding the axis L and having a hollow ring shape and abutting against the disc portion 111, a ring cover portion 22 connected to an inner circumferential edge of the bottom wall 21 and hermetically sleeved outside the sleeved portion 112, a circumferential wall 23 surrounding the axis L and connected to an outer circumferential edge of the bottom wall 21, a capsule cover portion 24 opposite to the bottom wall 21 and connected to the circumferential wall 23, and an abutting portion 25 engaged between the circumferential wall 23 and the capsule cover portion 24, wherein the bottom wall 21 has a bottom surface 211 hermetically abutting against the disc portion 111, and the circumferential wall 23 has an outer circumferential surface 231 and a pair of engaging portions 232 protruding from the outer circumferential surface 231 and having a tenon shape and being capable of being engaged with the positioning portion 124. The thickness of the cover portion 24 is smaller than that of the peripheral wall 23, the abutting portion 25 gradually decreases in thickness as it extends from the peripheral wall 23 toward the cover portion 24, the abutting portion 25 is also curved in an arc shape in cooperation with the top edge 123 of the supporting section 122, and has a pair of outer side surfaces 251 respectively corresponding to the top edges 123, the outer side surfaces 251 gradually incline outward as they extend from the peripheral wall 23 toward the cover portion 24, and the outer side surfaces 251 each have a first end 252 corresponding to the locking portion 232, a second end 253 circumferentially opposite to the first end 252 and corresponding to the terminal 126, and a bottom edge 254 engaged with the outer peripheral surface 231, a first included angle θ 1 (see fig. 5) is generated between the first end 252 and the axis L, a second included angle θ 2 (see fig. 6) is generated between the second end 253 and the axis L, and the outer side surfaces 251 extend from the first end 252 toward the second end 253, the included angle between the axis L and the shaft line is gradually increased. And the soft cover unit 20 can be converted from an original state (see fig. 5 and 6) to an inflatable closed state (see fig. 7 and 8), when the soft cover unit 20 is in the original state, the outer side surface 251 of the abutting portion 25 is not in contact with the top edge 123, and a gap of not less than 2 mm is formed between the bottom edge 254 and the top edge 123.

As shown in fig. 3 to 6, when the breathing mask of the present invention is assembled, the mask portion 24 of the soft mask unit 20 can be placed on the outside of the nose of the human body, and before the pressurized gas is supplied from the gas duct 30, the mask portion 24 is not expanded and deformed, and the outer side 251 of the abutting portion 25 is not in contact with the top edge 123.

As shown in fig. 3, 7 and 8, when the pressurized gas is input from the gas tube 30 and the inside of the flexible cover unit 20 is in an inflated and sealed state, the gas pressure inside the flexible cover unit 20 is greater than the atmospheric pressure, the bottom wall 21 is acted by the gas pressure, so that the bottom surface 211 is hermetically attached to the disk portion 111 (see fig. 3 in a matching manner), and the annular sleeve portion 22 is hermetically sleeved outside the sleeve portion 112, so that the air does not leak from between the bottom of the flexible cover unit 20 and the base 11. At the same time, the peripheral wall 23, the cover portion 24 and the abutting portion 25 are inflated by the pressurized gas (see arrows in fig. 7), and especially the outer side surface 251 of the abutting portion 25 abuts against the top edge 123 respectively due to the inflation deformation.

At this time, the soft cover unit 20 abuts against the top edge 123 of the wing frame 12 by using the abutting portion 25, so that not only stable positioning can be achieved, but also the soft cover unit 20 can generate a buffering balance effect without deformation caused by the action of gas pressure, and gas can not leak from between the bag cover portion 24 and the nose of the human body, so as to achieve a better gas supply effect. And by utilizing the effect of the gap not less than 2 mm generated between the bottom edge 254 and the top edge 123, a space capable of allowing the abutting portion 25 to generate elastic deformation can be generated, and by utilizing the effect of the first included angle θ 1 generated between the first end 252 and the axis L and the second included angle θ 2 generated between the second end 253 and the axis L, the deformation capability corresponding to the abutting portion 25 at the second end 253 is better than the deformation capability corresponding to the first end 252, so that better adhesion between the two sides of the bridge of the nose and the bag cover portion 24 can be ensured.

In conclusion, the breathing mask of the invention has simple integral structure, can generate better leakage-proof effect when being worn, and can really achieve the aim of the invention.
