Example Embodiment

[0019] In order to make it easy to understand the technical means, creative features, objectives and effects achieved by the present invention, the present invention will be further explained below in conjunction with specific drawings.

[0020] Such as figure 1 , figure 2 , Figure 4 As shown, a three-dimensional dust-proof filter cover includes a cover body 1 for covering the nose and mouth. The cover body 1 is symmetrically divided into a first cover part 101 and a second cover part by a longitudinal crease 2 located in the middle of the cover body. Part 102, one end of the first shielding part 101 and the second shielding part 102 are both connected with a buckle strap 3, which is an elastic band with a certain stretched length, and the upper end of the longitudinal crease 2 is located at the first shielding portion 101 The connection with the second shielding portion 102 extends upwards with a nose guard 103 that has a certain curvature and can fit on the human nose. The no...

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...
