Personal breathing apparatus with negative and positive pressure adjustable structure

摘要

The present invention relates to a personal breathing apparatus, and specifically, external air or purified, sterilized, heated/cooled air is supplied through a suction hole to maintain the facial space in a positive pressure state, or a facial space through a discharge hole in the positive pressure state. It relates to a personal breathing apparatus having a structure that can control negative and positive pressures, in which the space part is created in a negative pressure state to promote air circulation to protect it from viruses and bacteria, The specific solution of the present invention is, "A pad 100 is formed on the inside of the front side to be in close contact with the forehead in a rounded shape so that it can be closely attached to the forehead of the wearer's head, and the suction hole 110 and the discharge hole 120 are vertically formed on the upper surface of the pad 100, respectively. It is provided through and on the outside is formed a shape maintenance fixing board 130 of a round shape so as to maintain the shape of the pad 100 and fix it on the forehead, and is coupled with both ends of the shape maintenance fixing board 130 on the back side to the wearer It is fixedly coupled between the body 10 provided with an elastic band 140 for elastically fixed to the head of the body 10 and the pad 100 and the shape-maintaining fixing board 130 so as to extend downwardly and elongate to the wearer's head. A personal breathing apparatus having a structure capable of adjusting negative and positive pressures including a see-through shield portion 20 while being rounded on both sides to cover the entire face and forming a facial space 200 between the face and, The shield unit 20 is a personal breathing apparatus having a structure capable of adjusting negative and positive pressures, including those in the form of being rounded inward from the periphery of the wearer in the downward direction to surround the chin of the wearer; The facial space 200 includes a personal breathing apparatus having a structure capable of adjusting negative pressure and positive pressure, including receiving external air supplied from the suction hole 110 and maintaining a positive pressure state; The facial space 200 includes a personal breathing apparatus having a structure capable of controlling negative and positive pressures, including discharging air to the discharge hole 120 to maintain a negative pressure state; The facial space 200 discharges air to the discharge hole 120 to maintain a negative pressure state, and includes an antibacterial filter 210 at the end of the shield 20 to remove indoor air from the facial space 200 . ) and a personal breathing apparatus having a structure that can control negative and positive pressure, The facial space 200 receives external air from the suction hole 110 and maintains the positive pressure state, and through the discharge hole 120, the facial space 200 is circulated in a negative pressure state. A personal breathing apparatus having a structure capable of adjusting negative and positive pressures, including to facilitate palpation; A personal breathing apparatus having a structure in which negative and positive pressures can be adjusted, including an antibacterial filter unit 210 comprising a cover unit 211 and a filter unit 212 at the end of the shield unit 20; The cover part 211 is formed of any one material of polypropylene (POLYPROPYLENE), polyethylene terephthalate, polyethylene terephthalate glycol, polycarbonate, elastomer (ELASTOMER) and silicone (SILICONE) negative pressure and positive pressure controllable structure A personal breathing apparatus having a The filter unit 212 is A manganese-based catalyst is used to decompose ozone, and a manganese-based nanofiber prepared by electrospinning a solution in which a polymer and a manganese-based catalyst is dissolved is coated on a panel network, and the solution is 3 to 20 wt% of a polymer, manganese-based Consists of 25 to 15% by weight of catalyst and 65 to 945% by weight of solvent, the diameter of the manganese-based nanofiber is formed to be 5nm to 150μm, and when the manganese-based nanofiber is coated, silver nanoparticles or titanium dioxide particles are added. As a constitutive feature of "a personal breathing apparatus having a structure that can control negative and positive pressures, including those The present invention has the effect of blocking viruses or bacteria floating and circulating in the air as well as the basic effect of blocking droplets that are directly scattered, and enables stable living indoors without any obstacles to communication or breathing.
