The exhaust valve 16 has a function of allowing an air flow from the inside to the outside of the mask body 10 and blocking an air flow from the outside to the inside of the mask body 10. By employing the exhaust valve 16, the air discharged from the nose 51 and the mouth 5210 can be easily discharged from the mask body to the outside, and breathing is facilitated.

  Next, a method of using the face wearing mask 1 and its operation will be described.

  When starting use, first, the filter unit 20 is connected to the mask body 10. The filter 20 part is connected by engaging the engaging groove 23 of the connecting cylinder part 22 with the connecting pin 13 of the mask body 10. Here, the engaging pin portion 13a of the connecting pin 13 is inserted into the engaging groove 23, and the filter portion 20 is rotated about the axis E in the direction of arrow F as shown in FIG. The part 13a moves to the back side groove part 23c via the inclined groove part 23b. When the engaging pin portion 13 a forms the inclined groove portion 23 b, the tip end surface of the cylindrical portion 12 a of the mask main body 10 moves toward the packing 25. And when the engaging pin part 13a reaches | attains the back | inner side groove part 23c and is engaged with the lock groove part 23c, the front end surface of the cylinder part 12a of the mask main body 10 will be in the state which pressed the packing 25 fully. Thereby, in the state where the connection between the mask body 10 and the filter unit 20 is completed, the first air passage 14 on the mask body 10 side and the second air passage 28 on the filter unit 20 side are in communication with each other, The airtightness of the connecting portion between the mask body 10 and the filter unit 20 is maintained in a sufficiently high state.

  When the connection of the filter unit 20 to the mask body 10 is completed, the mask body 10 is attached to the face 50a.

Therefore, the mask body 10 has the face contact portion 11a on the face 50a. It will be in the state which contact | adhered completely, and a clearance gap will not arise in the contact part of the mask main body 10 and the face 50a. Here, since the mask main body 10 is composed of a thin elastic member, even when the mounting force to the face 50a of the mask main body 10 by the holding band 15 is increased, the entire mask main body 10 is easily elastically deformed, The face-contact part 11a does not bite into the face 50a strongly, and a feeling of pressure can be eliminated.

  Further, since the mask body 10 does not have air permeability, breathing through the nose 51 and the mouth 52 is always performed through the filter body 26. Since the filter unit 20 communicates with the inside of the mask body 10 via the filter body 26, the air flowing in from the filter body 26 is sent to the human body from the nose 51 and the mouth 52 via the filter body 26. Since the filter body 26 has a function of capturing the influenza virus floating in the air, the influenza virus is completely removed from the air sent to the nose 51 and the mouth 52, and the influenza virus enters the human body. Can be prevented.

  In recent years, there have been signs of epidemic of bird flu and new influenza with highly toxic viruses, and it is necessary to completely block the entry of these viruses into the human body 50. As in this embodiment, The mask body 10 has a structure that does not have air permeability, and the mask body 10 is completely brought into close contact with the face, so that breathing is performed only through the filter body 26, and the bird flu virus and the new influenza virus are contained in the human body 50. Can be surely prevented.

  The filter unit 20 is removed from the mask body 10 and discarded after being used for a certain period. Here, when removing the filter part 20 from the mask main body 10, first, the engagement of the connecting pin 13 with the engaging pin part 13a and the lock groove part 23c is released. Thereafter, the connecting pin 13 is withdrawn from the engaging groove 23 by rotating the filter portion 20 about the axis E shown in FIG. 11 in the direction opposite to the arrow F direction. And the new filter part 20 is attached to the mask main body 10 in the above-mentioned procedure.

  FIG. 14 shows the usage state of the face wearing mask 1. As shown in FIG. 14, since the mask main body 10 is in a state where the mask main body 10 and the holding case 21 are covered with a cup-shaped filter main body 26, only the cup-shaped filter main body 26 in the filter portion 20 is externally seen. Will be visible and the appearance will improve. Therefore, it is possible to use the face wearing mask 1 without hesitation in customer service or commuting, and it is possible to use in a wide range of fields.

  The embodiment of the present invention has been described in detail above, but the specific configuration is not limited to the above-described embodiment, and even if there is a design change or the like without departing from the gist of the present invention, It is included in this invention. For example, in this embodiment, the cover 11 of the mask body 10 is entirely made of an elastic member. However, at least the face contact portion 11a that is in close contact with the face is made of an elastic member, and other parts are not breathable. You may make it comprise from a member. Further, the elastic member of the mask main body 10 is not limited to silicone rubber, and may be configured using soft raw rubber that easily elastically deforms. And the connection structure of the connection port 12 and the filter part 20 is not limited to the structure using the connection pin 13, It is good also as a screwing structure using a screw | thread.

  Furthermore, in this embodiment, the filter main body 26 composed of a single sheet-like member blocks the entry of the avian influenza virus or the new influenza virus into the human body 50. It is good also as a structure which uses the main body 26 in piles. In addition, the filter body 26 is of a type that can capture droplets of a size of 0.08 μm or more, such as avian influenza virus or a new influenza virus.
