Novel mask

Abstract

The invention discloses a novel mask which comprises a mask body.A breather valve is installed on the mask body.The two ends of the mask body are connected with ear shields which can shield the ears respectively.The middle of the mask body is supported outwards to form a gas buffer area.An exhaust opening is formed in the lower portion of the mask body.An installation base comprises an inner clamping plate and an inner annular table.The inner annular table is arranged inside the exhaust opening in a sleeved mode from the inner side of the mask body and penetrates out.A guiding column is arranged in the center of an inner through hole.A plurality of connecting rods are arranged between the outer surface of the guiding column and the inner surface of the inner through hole and annularly distributed on the outer surface of the guiding column to support and fix the guiding column.An air outlet channel is formed between every two adjacent connecting rods.A through hole is formed in the middle of a membrane, the guiding column is sleeved with the membrane, and the membrane can slide along the guiding column so as to control on-off of the air outlet channel.A valve cover comprises an outer clamping plate and an outer annular table.A sealing plate is arranged on the top of the outer annular table.An air outlet is formed in the side portion of the outer annular table.The outer clamping plate is screwed to the inner annular table so that the outer clamping plate and the inner clamping plate clamp the mask body.

Description

technical field [0001] The invention relates to a mask, in particular to a novel mask. Background technique [0002] In winter, the temperature is low, the air is dry, and there are many dust and bacteria in the air. If you breathe this air for a long time, it is easy to cause the weak patients and patients with chronic bronchitis to be infected with respiratory diseases. Will wear a mask. Wearing a mask on the mouth and nose can filter the air entering the mouth and nose to prevent harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. Masks are mostly made of gauze. Currently there are special PM2.5 masks, but this Although masks can effectively filter dust and bacteria, they are generally disposable and need to be replaced after a period of use. Moreover, this type of mask is not suitable for people who need to wear glasses. The temperature of the air is relatively high. Due to wearing a mask, the exhaled gas cannot be discharged in ti...

Problems solved by technology

Wearing a mask on the mouth and nose can filter the air entering the mouth and nose to prevent harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. Masks are mostly made of gauze. Currently there are special PM2.5 masks, but this Although masks can effectively filter dust and bacteria, they are generally disposable and need to be replaced after a period of use. Moreover, this type of mask is not suitable for people who need to wear glasses. The temperature of the air is relatively high. Due to wearing a mask, the exhaled gas cannot be discharged in time, and part of the gas escapes from the upper part of the mask. The higher temperature gas liquefies when it encounters the lower temperature lens, causing a layer of mist to form on the surface of the lens. obstructed, affecting normal walking

The current masks are difficult to solve this problem, resulting in the inability of people wearing glasses to use masks, which eventually makes some people susceptible to respiratory diseases
