Description
Technical Field
The invention relates to the field of protective devices, in particular to a breathing device.
Background
Breathing apparatus comprising a mask body has become a highly practical device, both on the nose and mouth of a user. In use, contaminated ambient air is separated from the interior of the mask by the filter structure, and further, objects containing particles, germs, etc. are blocked on the mask body for protecting individuals from inhaling contaminants present in the surrounding environment.
Among the breathing apparatuses, a foldable breathing apparatus is a type that is excellent in performance, and a mask body provides convenience in carrying by being foldable. In order to form a certain air space between the inner layer of the mask body and the mouth and the nose of a user and facilitate folding of the mask, a suture line is arranged on the center line of the mask to enable the mask body to deform outwards. With the development of technology, the suture thread achieves a suture effect by forming a welding section by laser welding, ultrasonic welding, or the like.
However, the prior art has drawbacks, for example, the foldable breathing apparatus on the market has only one clamping strip, which limits the orientation of the breathing apparatus, and this limitation is obvious for users with different facial shapes of different sexes and ages, and the different facial shapes and different use habits make users have certain requirements for wearing diversity of the mask, and the mask with a single specification is difficult to be applied to users with different facial shapes, resulting in some people (especially children), and because the height of the nose is low and the facial shape of the nose area is small, the layering of the nose cannot well press the mask body on the face, and only breathing apparatus with a specific model can be purchased, and in some cases, because of the limitation of the source of goods, even some people have difficulty in purchasing a proper breathing apparatus. In addition, the foldable breathing device is provided with only one clamping strip which is arranged above the mask body, so that for users with different facial shapes, the mask has the defect of tightness, particularly the mandible of some facial shapes retracts, or the mandible of a thin facial shape is not round, the defect of poor mandible sealing exists, and the protection effect of the breathing device is seriously reduced. In addition, the foldable breathing device lower jaw on the market only provides mask body shape support by the non-woven fabric layer and the filter layer of the mask body, and the flexibility of the fabric layer is not enough to maintain the three-dimensional structure of the breathing device at the mouth and nose, so that a user feels pressure on the mouth and nose.
In some prior art, the suture lines are not reasonable in up-and-down arrangement and angle design, so that the comfort experience of the user and the sealing protection performance of the mask are poor.
In some prior art, the clamping piece of face guard adopts built-in design, and when tensioning the face guard area, built-in clamping piece can be along with the face guard area is dragged and is out of shape, can't effectively seal nasal part, and the protective effect is relatively poor. Adopt external holder design among the prior art of some, nevertheless with the holder complete fixation in the outer non-woven fabrics outside, also have similar defect.
Furthermore, nowadays, the number of people wearing glasses is increasing, and for many users wearing glasses, one problem faced when using masks is that the glasses easily slip off.

A first deformable gripping strip 7 is adjacent the first edge and a second deformable gripping strip 11 is adjacent the second edge. A first deformable gripping strip 7 extends from the first portion 101 across the first segment centre line 2 and to the second portion 102 and a second deformable gripping strip 11 extends from the first portion 101 across the third segment centre line 4 and to the second portion 102. Wherein the first welding section 5 extends to the first edge of the mask body 1, the first welding section 5 being 6.3-6.9cm, for example 6.6cm, in length. The second welding section 6 has a length of 6.2-6.8cm, for example 6.5 cm. The second welding section 6 is at a distance of 5.5-6.1cm, for example 5.8cm, from the second edge of the mask body 1. Wherein, the first edge and the second edge are the edges at two opposite sides.
Therefore, the breathing device can be respectively suitable for wearing in different facial shapes, and the selection of users with different facial shapes is increased.
