Embodiment 1

[0029] Embodiment 1 The sealing device of multi-finger pressure grid formula self-adaptive individualized mouth mask

[0030] refer to Figure 1-5 , Figure 19 , the device of the present invention consists of a pressing finger assembly 1, a middle warp 2, an oblique warp A3, a weft warp 4, an oblique warp B5, a tie elastic assembly 6, a right tie 7, a left tie 8, a round frame 9 and a bridge column 10 constitute. The whole device is approximately a semi-spherical three-dimensional frame. see Figure 19 , the circular frame 9 of three-quarters of the arc (that is, the arc corresponding to the 270-degree angle) is the arc skeleton, and the remaining one-quarter of the arc (that is, the arc corresponding to the 90-degree angle) is the pressing finger component 1 Group, the pressure finger assembly 1 group is formed by 34 pressure finger assembly 1 sides sticking to each other, and the quarter arc forms an angle of 60 degrees with the circular frame 9, and the circular frame ...

Embodiment 2

[0035] Embodiment 2 The sealing device of multi-finger pressure grid type self-adaptive individualized mask

[0036] First wear a disposable mask normally, and then cover the device outside the mask.

[0037] Wearing process: Hold the device with one hand and place it on the outside of the disposable mask. The arc ring formed by the pressure finger assembly 1 corresponds to the position of the bridge of the nose, ensuring that the frame of the device and each pressure ball 37 do not exceed the edge of the disposable mask. The other hand hangs the right frenulum 7 and the left frenulum 8 to the rear edge of the outer auricle, and then operates the frenulum elastic assembly 6 .

[0038] refer to Figure 9-18 , operate the strap elastic assembly 6 . For one-handed operation, the thumb focuses on the handle 22, the index finger or other fingers focus on the outside of the D ring 11, and the two fingers perform a closing action. The handle 22 is pushed, because the stop block 23...

Abstract

The invention provides a sealing device of a multi-finger pressing grid type self-adaptive individualized mask, which consists of pressing finger assemblies, a middle warp, an oblique warp A, a weft warp, an oblique warp B, a lacing elastic assembly, a right lacing, a left lacing, a segmental frame and a bridge column. The side surfaces of the pressing finger assemblies 1 are mutually adhered to form a pressing finger assembly group, and the segmental frame pressing finger assembly group forms a semi-spherical three-dimensional frame. An arc-shaped pressure belt is formed by a plurality of point pressure springs and is similar to a barrier, pressurizing sealing of the whole line of the special-shaped structure of the nose bridge part can be achieved, the spring pressure grids can be attached to the face gully skin of the nose bridge and the nose wings of any person, and tightness adjustment of the lacing can be achieved by operating the lacing with one hand through the lacing elastic assembly. The one-way locking of a ratchet wheel realizes that the lacing is always kept in a tight state in a natural state; and the device is reasonable in design, easy to manufacture, low in cost, capable of being repeatedly used and sterilized and disinfected through gas (or irradiation) and particularly suitable for supplementing and perfecting disposable masks.

Description

technical field [0001] The invention belongs to accessories of protective equipment, and relates to a multi-finger pressure grid type self-adaptive individualized mask sealing device, which is used for wearing masks such as masks, and especially solves the sealing of special-shaped structures on the face such as the bridge of the nose and the wings of the nose. Background technique [0002] Disposable masks are made of more than three layers of 28 grams of non-woven fabrics; the bridge of the nose is made of environmentally friendly full plastic strips. According to the protection level and material classification, it can be divided into ordinary disposable masks, medical disposable masks and medical surgical masks, etc., size 17.5 About cmx9.5cm, the straps are elastic and strappy. It has anti-virus, deodorant, bacteria-filtering, and dust-blocking effects, and is easy to wear, comfortable, and low in cost. It is widely used in daily life and medical use. However, the foll...
