Embodiment 1

[0027] The disposable high-protection mouth and nose mask provided by the invention comprises:

[0028] The fixing part 1, the part of the fixing part 1 corresponding to the oral cavity is provided with a first gap;

[0029] The mouth covering part 2 is arranged at the first gap of the fixing part 1, and is detachably connected with the fixing part 1. The mouth covering part 2 is also provided with a first fold part 3 with upward folds on the outside;

[0030] The nasal cavity covering part 4 is provided with a second fold part 5 with the outer folds facing downward;

[0031] Two easy-to-deform parts 6 are located in the receiving chambers provided on the fixing part 1 corresponding to one of them. The two receiving cavities are arranged along the length direction of the fixing part, and one of the receiving cavities is located between the mouth covering part 2 and the nasal cavity. Between the covering parts 4, another accommodating cavity is located above the nasal cavity c...

Embodiment 2

[0037] On the basis of Embodiment 1, a second notch corresponding to the nasal cavity is also provided on the fixing part 1 of this example, and the nasal cavity covering part 4 is disposed at the second notch and is detachably connected with the fixing part 1 .

[0038] In this embodiment, the nasal cavity covering part 4 and the oral cavity covering part 2 are detachably connected by the same method, which meets the needs of inspecting the nasal cavity or other situations where the nasal cavity needs to be exposed but the oral cavity does not need to be exposed.

[0039] In the above embodiment, the mouth covering part 2 and the nasal cavity covering part 4 are detachably connected to the fixed part 1 through non-woven double-sided adhesive tape;

[0040] The ear-hanging parts 7 are made of rubber bands or elastic ropes covered with water-absorbing non-woven fabrics.

[0041] The easily deformable part 6 is an aluminum-plastic strip or an aluminum-plastic sheet.

Embodiment 3

[0043] In order to further reduce the gas circulation in the oral cavity and nasal cavity, on the basis of the above embodiments, the easily deformable part 6 of this embodiment is an aluminum-plastic strip or a deformable plastic strip, and the aluminum-plastic strip or deformable plastic strip is close to the side of the human body There is also non-woven double-sided tape on the top. The purpose is to make the aluminum-plastic strip or the deformable plastic strip better fit the face.

Abstract

The invention discloses a disposable high-protection mouth-nose mask, and belongs to the technical field of safety protection articles. The mouth-nose mask comprises a fixing part, and a notch is formed in the portion, corresponding to an oral cavity, of the fixing part. An oral cavity covering part is arranged at the notch, corresponding to the oral cavity, of the fixing part, is detachably connected with the fixing part and is further provided with a first wrinkle part with an upward external wrinkle; a second wrinkle part with a downward external wrinkle is arranged on a nasal cavity covering part; two easily-deformed parts are located in containing cavities, corresponding to the easily-deformed parts one to one, of the fixing part, the two containing cavities are formed in the length direction of the fixing part, one containing cavity is located between the oral cavity covering part and the nasal cavity covering part, and the other containing cavity is located above the nasal cavity covering part. According to the mouth-nose mask, air circulation parts of the oral cavity and the nasal cavity are separated, air circulation between the oral cavity and the nasal cavity is reduced,and due to the appearance of the novel high-protection mouth-nose mask, the spreading of novel coronavirus can be effectively blocked, and the personal feeling of wearing the mask in daily life is improved.

Description

technical field [0001] The invention relates to the technical field of safety protection products, in particular to a disposable high-protection mouth and nose mask. Background technique [0002] The novel coronavirus pneumonia (COVID-19) epidemic has seriously endangered the lives and health of people all over the world, and the global economy has suffered huge losses. In the "war epidemic" against the new crown epidemic, wearing a mask is the most important weapon in our daily life, and it is also one of the important ways to cut off the droplets and air transmission of the virus. Since the new crown virus can exist for a long time, people wearing masks will become the norm. Coughing is a protective reflex movement of the human body. Mild and infrequent coughing helps to remove sputum or foreign objects in the airway, which is conducive to the control of respiratory infections. Inhaling the virus that you eliminate yourself is not conducive to physical recovery. [0003...
