Nasal mask

Abstract

The invention discloses a nasal mask. The nasal mask comprises a mask body, a sealing part, a filter part and an ear-hook unit, wherein the mask body defines a covering space and comprises a first assembly edge defining a covering opening and a second assembly edge defining a vent hole; the covering opening and the vent hole communicate with the covering space; the sealing part is arranged on the first assembly edge and extends along the covering opening in a surrounding mode; the filter part is combined to the second assembly edge detachably and covers the vent hole; and the ear-hook unit comprises two hanging frames combined with the mask body, and the two hanging frames are located on the two sides of the position, close to the covering opening, of the mask body. The nasal mask is used for being worn on the face of a wearer and covering the nasal part so as to filter air inhaled during breathing.

Description

technical field [0001] The present invention relates to a nasal mask for wearing on the face and covering the nose to filter the air inhaled during breathing. Background technique [0002] In order to prevent dust, suspended particles or virus bacteria in the air from entering the lungs and cardiovascular system through breathing and causing harm to health, people wear masks to filter the air they inhale. [0003] The covering area of ​​existing masks covers the mouth and nose, covering almost two-thirds of the face area. However, when breathing, most of the inhaled air is filtered by the filter material adjacent to the nose. The usage rate of the filter material in the area is extremely low, and there is a risk of waste. In addition, the filter material of the existing mask is easy to adhere to saliva so that its service life is reduced. Therefore, the existing masks require a large area of ​​filter material, and most of them are disposable consumables, which have the dis...

AI Technical Summary

Problems solved by technology

[0003] The covering area of ​​existing masks covers the mouth and nose, covering almost two-thirds of the face area. However, when breathing, most of the inhaled air is filtered by the filter material adjacent to the nose. The utilization rate of filter media in the area is extremely low, and there is a risk of waste

In addition, the filter material of the existing mask is easy to adhere to saliva and reduce its service life.

Therefore, the existing masks require a large area of ​​filter material, and most of them are disposable consumables, which have the disadvantages of poor utilization rate and environmental protection.

[0004] Furthermore, the existing mouth mask cannot form a seal so that the air only passes through the filter material, that is, the air is easily inhaled through the gap between the existing mouth mask and the face, resulting in the inability to reliably filter out harmful substances in the air.

[0005] In addition, when the existing masks are worn, the wearer's mouth is covered, which hinders eating and drinking, and also adversely affects the volume and clarity of the wearer's speech
