Problems solved by technology

[0002] The way humans humidify the dry air they inhale is to use the sol or gel layer on the nasal mucosa and tracheobronchial mucosa, and the dry gas flows through the surface of this type of moisture source material to bring water vapor into the airflow, thereby humidifying the dry air However, the humidification effect depends heavily on the integrity of the respiratory mucosal humidification structure and the normal function; while environmental pollution, smoking, fatigue, mental stress, drugs, drinking too little water, various diseases and other factors can affect the respiratory mucosal humidification. The effect of dehumidification of dry gas, the continuous flow of poorly humidified dry gas from the respiratory tract into the alveoli will affect lung function and reduce the resistance of the respiratory system, and the reduction of resistance is an endogenous factor in the occurrence of various respiratory infections
[0003] Patent 891014977 provides a humidification mask, which allows the inhaled gas to pass through a breathable and water-absorbable humidification pad and then inhale into the body, which plays a certain role in humidifying and inhaling dry gas, but the resistance of the gas passing through the water-absorbing material is bound to increase , the smoothness of the airflow is difficult to guarantee, and it is not a physiological humidification method, and the gas passing through the water-containing material usually produces obvious noise and can excite the liquid into an aerosol, resulting in associated risks

Embodiment 1

[0028] Example 1: Such as figure 1 , 2 As shown, the wet face mask includes at least an inner shell (1) and an outer shell (3), which are made of medical plastic material, and the humidification component (2) is a water-containing non-woven fabric or hydrogel and is located in the inner shell (1). In the gap between the outer casing (3) and the outer casing (3), the outer casing (3) is provided with an outer casing air inlet (3-1), and there is a gap between the outer casing (3) and the humidifying component (2), which is The humidification chamber (4), the inner casing (1) is provided with an inner casing air inlet (1-1), and the humidification component (2) is provided with a humidification component air inlet (2-1).

[0029] The inner shell (1) can be provided with a through part (1-2) for blowing the exhaled humidified air to the surface of the humidifying component (2) for adsorption of water vapor, thereby achieving the effect of reusing the exhaled moisture.

[0030] In orde...

Embodiment 2

[0032] Example 2: Such as image 3 As shown, the difference from Embodiment 1 is that the humidification component (2) is provided with an air filter component (5), and the air flows through the air filter component (5) through the air inlet (3-2) of the outer casing facing the filter component ) And then enter the humidification chamber (4). The filtered air flows through the surface of the humidification component (2) for humidification. After humidification, it enters the humidification component (2-3) and the other inner casing. The stomata (1-4) enter the human respiratory tract.

Embodiment 3

[0033] Example 3: Such as Figure 4 As shown, the difference from Embodiments 1 and 2 is that a part (1-3) of the inner casing (1) conforms to the contour of the nose, and there is no air inlet on it, which is used to isolate the nasal cavity from the outside and avoid The irritation of the nasal cavity from hot and cold air and light from outside.

[0034] In the present invention, one-way valves can be arranged on the inner and outer shells to facilitate exhalation from the nose, mouth or nose and mouth; heating components, negative ion generating components or volatile inhalables generating components can also be arranged in any parts and gaps.

[0035] The present invention can be provided with parts such as straps which are convenient to fix the product with the face.

[0036] The solution of the present invention can also be used only for humidification and filtration of the mouth while exposing the nose.

Abstract

A humidifying mask includes an inner shell, an outer shell and a humidifying component positioned in a clearance between the inner shell and the outer shell. The humidifying mask adopts bionic noiseless unobstructed surface humidification, and can efficiently filter the air; when the nasal cavity is required to be protected, the humidifying mask can be converted to oral breath; and meanwhile, the humidifying mask can fully utilize heat energy in exhaled air to warm inhaled air.

Description

Technical field [0001] The invention relates to a humidifying mask, which belongs to the technical field of daily necessities or medical products production. Background technique [0002] The way humans humidify the inhaled dry air is to use the sol or gel layer on the nasal mucosa and tracheobronchial mucosa. The dry gas flows through the surface of such wet source substances to bring water vapor into the airflow, thereby humidifying the dry air. But the humidification effect depends heavily on the integrity of the respiratory tract mucosal humidification structure and the normal function; environmental pollution, smoking, fatigue, mental stress, drugs, drinking too little water, various diseases and other factors can affect the respiratory tract mucosal wetness The effect of dehumidifying dry gas. The continuous flow of poorly humidified dry gas from the respiratory tract into the alveoli will affect lung function and reduce the resistance of the respiratory system. The reducti...
