The filter membrane 32 can be used in two different embodiments.
As shown in fig. 4, scheme one: the filter membrane 32 comprises a first filter layer 321, a second filter layer 322, a third filter layer 323, a fourth filter layer 324 and a fifth filter layer 325 which are sequentially attached from outside to inside, the first filter layer 321 and the fifth filter layer 325 are respectively composed of non-woven fabrics, the second filter layer 322 and the third filter layer 323 are both composed of melt-blown fabrics, and the fourth filter layer 324 is composed of electrostatic cotton.
In the technical scheme, the first filter layer 321 of the filter membrane 32 is 45g/m2The fifth filter layer 325 is 20g/m2The non-woven fabric with the specification, the second filter layer 322 and the third filter layer 323 adopt 25g/m2The fourth filter layer 324 is 95g/m2Static cotton of the specification. In the medical environment, particles with virus usually float in the air, but the particles can not exist independently, and the particles are usually attached to dust in the air to form aerosol, the filtering membrane 32 in the technical scheme blocks pollutants through multilayer interception and electrostatic effect, and meanwhile, the number and the thickness of the filtering layers are proper, so that the respiratory airflow resistance of a user can not be excessively increased, the human health is facilitated, through testing, by adopting the combination, the NaCl filtering efficiency is 98.8%, the airflow resistance is 11.50mmH2O, and both the filtering efficiency and the airflow resistance can meet the medical protection requirements.
As shown in fig. 5, scheme two: the filter membrane 32 comprises a first filter layer 321, a second filter layer 322, a third filter layer 323, a fourth filter layer 324 and a fifth filter layer 325 which are sequentially attached from outside to inside, the first filter layer 321 and the fifth filter layer 325 are respectively composed of non-woven fabrics, the second filter layer 322 and the fourth filter layer 324 are both composed of electrostatic cotton, and the third filter layer 323 is composed of melt-blown fabrics.
In the present technical solution, the first filter layer 321 is 45g/m2The fifth filter layer 325 is 20g/m2The nonwoven fabric, the second filter layer 322 and the fourth filter layer 324 are 95g/m2The third filter layer 323 is 25g/m of static cotton2Melt-blown cloth of the specification. Tests prove that the filtering membrane 32 in the technical scheme adopts the combination, the NaCl filtering efficiency is 96.55 percent, the airflow resistance is 6.23mmH2O, and both the filtering efficiency and the airflow resistance can meet the medical protection requirements.
There are at least three kinds of connected modes between sealed gasbag 4 and face guard shell 2, sealed gasbag 4 can adopt forms such as inflatable, double-colored shaping or silica gel fastener, one of them: the sealing air bag 4 is an inflatable air bag, and the sealing air bag 4 is adhered to the bottom periphery of the mask shell 2; the second step is as follows: one side of the periphery of the sealed air bag 4 facing the mask shell 2 is fixedly connected with an arc-shaped clamping groove, a bonding surface is arranged in the arc-shaped clamping groove, and the arc-shaped clamping groove and the edge of the mask shell 2 are matched and bonded into a whole; and thirdly: sealed gasbag 4 and face mask shell 2 are as an organic whole through double-colored injection molding technology integrated into one piece or through the buckle joint, avoid bonding the quality problem that insecure arouses between sealed gasbag 4 and the face mask shell 2.
As an alternative embodiment, as shown in FIG. 3, the present invention further comprises a head cover 6 capable of enclosing the head of the user, the head cover 6 is fixed to the bottom periphery of the mask shell 2, and the air bag 4 is enclosed in the head cover 6. The utility model discloses a hood 6 uses with current protective clothing cooperation, and hood 6 bottom can be packed into in the protective clothing.
As an optional embodiment, the utility model discloses still include with user's back brain radian matched with fixed string bag, the fixed band 5 that the 2 both sides of face guard shell set up is the elastic webbing, the elastic webbing is provided with four at least, the one end of elastic webbing is sewed up or is connected on face guard shell 2 through the buckle, the other end of elastic webbing is sewed up or is connected on fixed string bag through the buckle. When the mask is used, the fixed net bag is firstly covered on the hindbrain, the mask shell 2 is covered on the face, the elastic band can tightly fix the mask shell 2, the sealing air bag 4 can ensure that the mask shell 2 is attached to the face of a user, and the sealing performance of the attachment part is ensured. By adopting the design of the rear fixing net bag, the untight sealing caused by the displacement of the elastic band can be avoided, and the discomfort caused by the long-term fixing through the elastic band can be relieved.
Use the utility model discloses when protecting, earlier wear user's face with mask shell 2 through the fixed band 5 of 2 both sides of mask shell, sealed gasbag 4 under the extrusion, can realize with the inseparable laminating of user's face, guarantee the seal between mask shell 2 and the user face, filtering action can be realized to the filtration membrane 32 of 2 gas exchange openings departments of mask shell, avoids the user to call in the particulate matter of taking the virus.
