Problems solved by technology

In terms of structure: the existing planar respiratory protective masks (masks or nasal masks) or relatively rigid cup-shaped, which fit poorly with the face, especially the gaps on both sides of the bridge of the nose, where dust particles and pathogens are easy to enter, affecting protection Effect
Due to the influence of filter material defects and structural defects, most respiratory protective masks (masks or nasal masks) often have the disadvantages of poor protection effect, poor air permeability, and feeling stuffy or suffocating.

Embodiment 1

[0018] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 As shown, a novel respiratory protection mask comprises a plastic cover body 1, ear hooks 12, an exhaust pipe 2 arranged in the middle of the plastic cover body 1, an air intake pipe 3 arranged below the exhaust pipe 2, an air intake pipe arranged under the exhaust pipe 2 the one-way exhaust valve 4 at the end, the air supply device 5 located at the intake end of the intake pipe 3, the liquid filter device located at the intake end of the air supply device 5, and the negative ion device 6 located at the intake end of the intake pipe 3, the The plastic cover body 1 is a mouth mask when it is designed to block and protect the mouth and nose simultaneously, and is a nasal mask when it is designed to only block and protect the nose.

[0019] The plastic cover body 1 can be a non-toxic plastic, such as silica gel, which is molded by injection molding and is a three-dimensional cover body conform...

Embodiment 2

[0021] The one-way exhaust valve 4 includes a conical exhaust hood 41 located at the outlet end of the exhaust pipe 2, a valve core 42 disposed in the conical exhaust hood 41, and the exhaust hood 41 is provided with exhaust An air hole 44, a compression spring 43 is provided between the end surface of the exhaust cover 41 and the valve core 42, the valve core 42 is a sphere, or a cone with a wide outside and a narrow inside. The spool 42 can be a sphere or other conical body with a large top and a small bottom, can be a hollow body, can also be a solid body, and can be made of metal, plastic or other materials that meet safety requirements and process requirements. Requirement is: when exhaust cover 41 upwards, the weight of spool 42+the elastic force of spring 43, be less than the air-flow pressure that nostril exhales and the air-flow pressure that air intake pipe shunts into exhaust pipe 2. When a person exhales, the gas is exhaled from the nostrils, and the airflow enters...

Embodiment 3

[0023]Described gas supply device 5 comprises the miniature fan 51 that is located at the inlet end of air intake pipe 3, and described miniature fan 51 is electrically connected governor 52, and described governor 52 is provided with speed regulating switch 53, and described miniature fan 51 DC power supply 54 supplies power. The liquid filtering device includes a container 71, a container air inlet pipe 72 pierced through the container 71, a container air outlet pipe 73 pierced through the container 71, a water repellent film 74 arranged at the inner port of the container air outlet pipe 73, used for fixing the repellent The detachable pressure ring 75 of water film 74, the intake cover 77 that is located at the inner end of air outlet pipe 73, the universal head 76 that is located at the outside of the intake cover 75, the suspension body 761 that is located at the universal head side, is located at the suspension The lower end of the body 761 is not close to the weight blo...

Abstract

The invention relates to daily hygienic products, in particular to a novel respiratory protection mask. The novel respiratory protection mask comprises a plastic mask body, ear hooks, an exhaust pipe arranged in the middle of the plastic mask body, an air inlet pipe arranged below the exhaust pipe, a one-way exhaust device arranged at the tail end of the exhaust pipe, an air supply device arranged at the air inlet end of the air inlet pipe, a liquid filter device arranged below the air supply device, and a negative ion device arranged at the air inlet end of the air inlet pipe. Due to the arrangement of the structure, the airtightness and the filter effect of the respiratory protection mask are good, air can enter and exit smoothly, negative ions can be generated, the air supply amount can be adjusted, and the air fresh feeling which cannot be achieved by other similar products can be brought to wearers.

Description

technical field [0001] The invention relates to the field of daily hygiene products, in particular to a novel respiratory protection mask. Background technique [0002] Respiratory protective masks (masks or nasal masks) have a certain filtering effect on the air entering the respiratory system. When respiratory infectious diseases are prevalent, when working in dusty and other polluted environments, wearing respiratory protective masks (masks or nasal masks) is very effective. Good protection. It can be worn in places with many people and poor air circulation. When exercising outdoors, in order to resist wind, sand and cold, or to be active in an environment with air pollution, wearing a respiratory protective mask (mask or nasal mask) has a protective effect. Wearing it in hospitals, construction sites, and dusty environments can prevent the inhalation of pathogens and dust particles. But existing respiratory protective mask (mask or nasal mask) all adopts filtering mat...
