Detailed Description
The invention is further described with reference to the following figures and specific examples:
in examples, the invention discloses particulate matter filtering protective masks with spiral structures;
the mask includes: a helical structure, an adhesive medium, and a mask body;
the spiral structure is embedded on the outer surface of the mask body and used for filtering particles in the inhaled gas and releasing hot water vapor, carbon dioxide and other waste gases generated by breathing;
the spiral structure comprises a spiral pipe wall and spiral ribs arranged inside the pipe wall;
the inner wall of the spiral pipe wall and the spiral ribs are coated with adhesive media;
the spiral structure is used for inducing the gas flowing through to generate vortex, and promoting the particles, allergens, dust or other harmful substances in the air to move towards the inner wall of the spiral pipe wall and the spiral ribs, so that the particles, the allergens, the dust or other harmful substances are adhered to the adhesion medium.
In this embodiment, the mask body is a carrier installed in a spiral structure, so that the breathing resistance of the mask is lower in function, and the internal space is drier and cleaner.
The spiral structure is used for inducing gas flowing through to generate vortex, and promoting particles, allergens, dust or other harmful substances in the air to move towards the inner wall of the spiral pipe wall and the spiral ribs, so that the inhalable particles are adhered to the adhesion medium. Due to the openness of the structure, hot air, moisture, carbon dioxide and other waste gases generated by breathing can be promoted to be rapidly discharged out of the mask.
The spiral structure is arranged in the mask or on two sides of the mask, and plays a role in filtering particles, reducing breathing resistance and releasing hot air, moisture and waste gas generated by breathing. The spiral structure is placed between the base and the cover to play a role in protection. The size and filtering effect of the spiral structure can be adjusted according to the use environment.
The mask of the embodiment can prevent PM2.5, PM10 particles, allergens, pollen and the like from entering the respiratory system of a human. Can be used as reusable personal medical protective equipment for purifying inhaled gas and inhibiting or relieving the influence of harmful particulate matters.
The mask of the embodiment can effectively release hot air, moisture, waste gas and the like generated by breathing. Provides a comfortable breathing space for the user.
In embodiments, the lobed spiral wall is a four lobed spiral wall.
The four-lobe helical tube part is obtained by improving and deforming 'product with helical groove'; the university of nottingham owns the intellectual property rights of the prototype, under patent protection (patent No. WO 03/091578).
In embodiments, the spiral rib has a spiral configuration capable of mating with the wall of a four-lobed spiral tube.
In this embodiment, the spiral fins are used to increase the swirl, increase the contact area, prevent the particles from directly passing through, and promote the adsorption of the particles.
The number of the spiral ribs is related to the wave number of the lobe spiral pipe wall, the lobe spiral pipe wall with wave numbers can only correspond to spiral ribs at most, and the spiral ribs can be determined according to practical conditions, such as local air quality, practical economic conditions and the like.
In order to increase the contact area and improve the vortex, the lobe spiral pipe wall is a four-lobe spiral pipe wall, and the number of spiral ribs is equal to the wave number of the lobe spiral pipe wall.
In examples, the adhesion medium is a biodegradable biogel including or more of alkyl esters (alkyl ester), α -n-butyl cyanoacrylate (alpha cyano n-butyl acrylate), waterborne polyurethane (water borne polyurethane), urethane prepolymers (urea alkyl prepolymers), fluorinated aromatic isocyanates (fluorinated aromatic isocyanate), toluene diisocyanate (toluene diisocyanate), polypropylene glycols (PPG) and gelatin (gelatin).
The present example selects an existing degradable bio-gel as an adhesion medium, which has the characteristics of non-toxicity, no harm to human health, good biodegradability, and easy cleaning and removal, so that when the bio-gel loses efficacy, the gel can be removed and replaced with a new one in time.
