Abstract

The invention discloses a bionic intelligent mask, which mainly solves the problems of unsmooth breathing and contact of a filter product and air when not used in the prior art. The bionic intelligent mask device comprises a shell, wherein an air suction valve and an air outlet valve are arranged on the shell, one or more diaphragms made of elastic materials are arranged on the air suction valve and the air outlet valve, and notches are formed in the diaphragms. The incision is a divergent incision. Because the invention is equipped with one or more diaphragms made of elastic material on the air intake gate, air outlet gate, open the cut on the diaphragm, especially when dispersing the cut, when users breathe in or exhale, the air pressure in the body and air pressure outside the body produce the pressure difference, make the opening of dispersing on the diaphragm, make the outside air enter the body cavity of the body, or make the air in the body cavity of the body discharge outside the body, when users do not breathe, the diaphragm is closed under the effect of its internal tension, users breathe smoothly while using, and its filtered article does not contact with air when not using.

Description

Bionic Smart Mask Device

technical field

The invention relates to a mask, in particular to a bionic intelligent mask device which can prevent the intrusion of viruses, poisonous gases, etc., and ensure smooth breathing of users.

Background technique

In the recent outbreak of infectious atypical pneumonia in the world, in order to block the spread of the coronavirus, masks have become a daily carry item for people in the affected areas. In the remaining non-infested areas, people often wear masks to prevent accidents. There are two kinds of existing masks, one is made of textile fibers, and is provided with a multi-layer filter screen, which adheres to the filter screen to prevent viruses in the air sucked by the user from invading the human body. Low, after reaching a certain technical index, it can filter some viruses and other harmful substances from invading the human body from the mouth or respiratory tract, but it is difficult to fit naturally with the human face, and the virus can still penetrate into the mask through the gap between the mask and the face. In addition, when using it, the user will find it difficult to breathe, and after the humidity of the textile fibers in this mask increases, its protective efficiency will be greatly reduced and it cannot be used anymore; the other is used for military and military use. The anti-virus mask of high-pollution industry contains a shell with an inhalation valve and an air outlet valve on the shell. The inhalation valve and the air outlet valve are externally connected to a filter box, and the filter box is equipped with filter items such as activated carbon. The mask with this structure is suitable for use. The user can breathe smoothly when using it, and can better isolate the respiratory tract from the outside air, but the filter product will be in contact with the air for a long time, which will reduce its filtration efficiency, and the sealing performance is poor. The opening and closing are inflexible, which affects breathing, and the anti-virus effect is poor.

Contents of the invention

The purpose of the present invention is to provide a bionic intelligent mask device, the user breathes smoothly when using it, and its filter items do not contact with the air when not in use, and its further purpose is to fit the user's face better, Prevent viruses, poisonous gas, etc. from entering the mouth or respiratory tract of the human body from the gap between the mask and the user's face.

The bionic intelligent mask device of the present invention contains a shell, and the contact surface between the shell and the face of the human body is adapted to the shape of the face of the human body, and an inhalation door is opened on the shell at a position corresponding to the user's inhalation and exhalation direction And the outlet valve, one or more diaphragms made of elastic material are installed on the suction valve and the outlet valve, and a cut is arranged on the diaphragm. The incisions are divergent incisions.

An outer casing is arranged outside the casing, and the contact surface between the outer casing and the face of the human body is adapted to the shape of the human face, and holes are arranged on the outer casing at corresponding positions with the suction valve and the air outlet valve.

Due to the bionic intelligent mask device of the present invention, one or more diaphragms made of elastic material are housed on the suction valve and the gas outlet valve, and an incision is provided on the diaphragm, especially when the divergent incision is made, when the user inhales or Exhale, the pressure difference between the air pressure inside the shell and the air pressure outside the shell makes the divergent cut on the diaphragm open, allowing the outside air to enter the shell chamber, or the air in the shell chamber to be discharged out of the shell, when the user is not breathing , the diaphragm is closed under the action of its internal tension, and the user can breathe smoothly when using it, and the filter item does not contact the air when it is not in use; The contact point is sealed with soft materials such as silica gel. Through the sealing between the outer shell and the face, it can better fit the user's face and add a barrier to prevent viruses and poisonous gases from entering the human body from the gap between the mask and the face.

Detailed ways

The bionic intelligent mask device of the present invention, as Fig. 1, contains housing 1, and the contact surface of housing 1 and human body face is adapted to the shape of human body face, and breathing chamber 2 is formed between housing 1 and the face, and housing 1 The contact position with the face is equipped with soft and elastic items such as rubber and silica gel, so that the contact position between the shell and the face is sealed as much as possible. There is an inhalation door on the shell 1 corresponding to the user's inhalation and exhalation directions. 3 and the outlet valve 4, one or more diaphragms 5 made of elastic material are installed on the suction valve 3 and the outlet valve 4, and two or more than three cutouts 6 are opened on the diaphragm 5, and the cutouts 6 are Due to the limitation of the elastic size of the material, the divergent slit cannot be opened too large, and a plurality of diaphragms 5 can be installed on the suction valve 3 and the outlet valve 4. The housing 1 shown in Figure 1 is equipped with six diaphragms 5, The diaphragm 5 of the suction valve protrudes toward the inside of the housing, the diaphragm of the outlet valve protrudes outward of the housing, and the incision 6 or divergent incision is on the protrusion, as shown in Figures 5 and 6, In this way, the opening and closing of the cutout on the diaphragm 5 is not only effected by elastic force, but also the effect of the tension of the diaphragm 5 itself, so that the opening and closing is smoother and labor-saving. The inhalation valve 3 is near the nose of the face, and the air outlet valve 4 is located below the inhalation valve. The air outlet valve 4 has an inclination towards the nose direction to ensure smoother breathing. When using the bionic intelligent mask device of the present invention, the user only needs to place filter items in the casing according to the purpose of use to use as a mask, which is convenient for users to use in different occasions, and it is also very convenient to clean when the filter items are contaminated and replace.

Described diaphragm 5 is contained on a bottom plate 16 that is made of harder material, or a reinforced bottom plate 16 is housed around each diaphragm 5, as shown in Figure 7, when using thinner diaphragm like this, can guarantee the intensity of structure .

Outer casing 7 is housed, as Fig. 2,3,4, and the contact surface of outer casing 7 and human body face is adapted to the shape of human body face, on the outer casing 7 and the corresponding position of suction valve 3 and outlet valve 4 Have hole 8 on it. There are screw holes 9 at the corresponding positions between the outer casing and the casing, and the outer casing and the casing are connected by screws; wing-shaped plates 10 protrude from both sides of the outer casing, and there are holes on the wing-shaped plates 10 for assembling rubber ropes, etc. Groove 11.
