Three-dimensional dustproof filtering mask

Abstract

The invention relates to the technical field of masks, in particular to a three-dimensional dustproof filtering mask. The three-dimensional dustproof filtering mask comprises a mask body used for covering the mouth and the nose, the mask body is symmetrically divided into a first covering part and a second covering part by a longitudinal folding line in the middle of the mask body. One end of the first covering part and one end of the second covering part are respectively connected with an ear fastening belt. The ear fastening belts are elastic belts with a certain stretched length. The upper end of the longitudinal folding line, located at the joint of the first covering part and the second covering part, extends upwards to form a nose protection part having a certain camber and being capable of being attached to the nose. The nose protection part is designed based on the camber of the nose with the outside protruding outwards and an attaching groove capable of being attached to the nose formed inside. The lower end of the longitudinal folding line, located at the joint of the first covering part and the second covering part, extends downwards to form an attaching part having a certain camber and being capable of being attached to the lower jaw. A three-dimensional area allowing people to breathe freely is formed between the nose protection part and the attaching part. When a user wears the three-dimensional dustproof filtering mask, a three-dimensional effect is achieved on the face, and the mask is closely attached to the face. In addition, free breathing is guaranteed and the user feels comfortable.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to a three-dimensional dustproof filter mask. Background technique [0002] Masks can generally be divided into air filter masks and air supply masks. It is designed for people's health, and is used to prevent some visible or invisible substances that are harmful to the human body from filtering, so as not to have a bad influence on the human body. Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. From the perspective of human physiological structure, because the blood circulation of the nasal mucosa is very strong and the passages in the nasal cavity are very tortuous, the nasal hairs form a "barrier" for filtering. When air is sucked into the nostrils, the airflow forms a vortex in the tortuous channel, which warms the ai...

AI Technical Summary

Problems solved by technology

If you wear a mask for a long time, the nasal mucosa will become fragile and lose the original physiological function of the nasal cavity, so you cannot wear a mask for a long time
