Anti-fogging mask

Abstract

The anti-fogging mask comprises a mask body and a flow guide device, and the flow guide device comprises a breather pipe, an air outlet pipe and an air inlet pipe which are communicated with one another; the air outlet pipe and the air inlet pipe are arranged in parallel up and down, the air inlet end of the air outlet pipe is connected to the air outlet end of the breather pipe, and the air outlet end of the air inlet pipe is connected to the air inlet end of the breather pipe; the air outlet pipe is provided with an air outlet hole which is provided with a downward opening and is used for discharging air, and the air inlet pipe is provided with an air inlet hole which is provided with an upward opening and is used for feeding air; the breather pipe is arranged outside the mask body, and the air outlet pipe and the air inlet pipe are arranged inside the mask body. The anti-fogging mask comprises a mask body and a flow guide device. The anti-fogging mask provided by the invention is beneficial to preventing glasses from fogging and is beneficial to avoiding leakage of pollutants.

Description

technical field [0001] The invention relates to the field of masks, in particular to an anti-fogging mask. Background technique [0002] The existing mask structure is not friendly to users who wear glasses. It is mainly reflected in the fact that when such users exhale while wearing a mask, the glasses lenses are prone to fogging, which affects vision, especially when the outdoor temperature is low. In order to solve the problem of glasses fogging, currently there are probably the following methods: First, the mask is provided with elastic shaping strips or sponge pads, which are generally set at the position corresponding to the mask and the bridge of the nose of the human body. However, its airtightness is low and air leakage is serious. No anti-fogging effect can be achieved; secondly, a one-way breathing valve is set on the mask, and the gas exhaled by the user can be directly discharged out of the mask through the breathing valve, but this structure is not suitable for...

[0002] The existing mask structure is not friendly to users who wear glasses. It is mainly reflected in the fact that when such users exhale while wearing a mask, the glasses lenses are prone to fogging, which affects the field of vision, especially when the outdoor temperature is low.

In order to solve the problem of glasses fogging, currently there are probably the following methods: First, the mask is provided with elastic shaping strips or sponge pads, which are generally set at the position corresponding to the mask and the bridge of the nose of the human body. However, its airtightness is low and air leakage is serious. No anti-fogging effect can be achieved; secondly, a one-way breathing valve is set on the mask, and the gas exhaled by the user can be directly discharged out of the mask through the breathing valve, but this structure is not suitable for infecting patients, especially During the new crown epidemic, the gas exhaled by the user is discharged without being filtered by the mask, which may easily cause the leakage of gas pollutants, so it is prohibited in formal occasions; The gas is forced to be exported from the side or bottom of the mask, and this structure also has the risk of contamination
