Description

TECHNICAL FIELD

The invention relates to a mask, in particular to a bionic intelligent mask device which can prevent the invasion of viruses and poisonous gases, and also guarantees the user's smooth breathing. Background technique

Recently, infectious atypical pneumonia has erupted globally. In order to prevent the spread of coronavirus, masks have become daily items in the epidemic area. In other non-epidemic areas, people often wear masks to prevent accidents. There are two types of existing masks. One is made of textile fibers and is provided with a multi-layer filter to adhere viruses and other air inhaled by the user to the filter to prevent it from invading the human body. The cost of this mask is Low, after reaching a certain technical index, it can filter some viruses and other harmful substances from entering 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 infiltrate into the use through the gap between the mask and the face. In addition, the mouth and nose of the user may be difficult to breathe. In addition, after the humidity of the textile fibers in the mask increases, its protective effect is greatly reduced and it can no longer be used. The other is used for military and High-pollution industrial gas masks, which contain a casing, which has an intake valve and an exhaust valve on the casing. The intake valve and the exhaust valve are externally connected to a filter box. The filter box contains filtering materials such as activated carbon. The user can breathe smoothly during use, which can better isolate the respiratory tract from the outside air, but its filter products will be in contact with the air for a long time, which will reduce its filtering efficiency Poor, inspiratory and expiratory door door with a mechanical structure, open, closed inflexible, Respiration, and poor anti-virus effect. Summary of the Invention

The purpose of the present invention is to provide a bionic smart mask device, which allows the user to breathe smoothly during use, and the filter article is not in contact with the air when not in use, and further aims to better fit the user's face, Prevent viruses and poisonous gas 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 according to the present invention comprises a shell, and the contact surface between the shell and the human face is adapted to the shape of the human face. An suction valve is opened on the shell at a position corresponding to the user's inhalation and exhalation directions. And air outlet valve, one or more diaphragms made of elastic material are installed on the air inlet valve and the air outlet valve. Incision. The incision is a divergent incision

An outer shell is installed outside the shell, and the contact surface between the outer shell and the human face is adapted to the shape of the human face, and holes are formed in the outer shell and corresponding positions of the intake valve and the exhaust valve.

Due to the bionic intelligent mask device of the present invention, one or more diaphragms made of elastic material are installed on the intake valve and the exhaust valve, and a cut is made in the diaphragm, especially when the user inhales or Exhale, the air pressure inside the casing creates a pressure difference with the air pressure outside the casing, so that the divergent incision on the diaphragm is opened to allow outside air to enter the casing cavity, or to exhaust the air in the casing cavity out of the casing. The diaphragm is closed under the action of its internal tension, and the user can breathe smoothly when in use, and the filter articles do not contact the air when not in use; an outer shell is installed outside the shell, the outer shell contacts the human face, and the outer shell contacts the face The contact position is sealed with a soft item such as silicone. The outer body and the face are sealed to better fit the user's face, adding a barrier to prevent viruses and poisonous gas from entering the human body from the gap between the mask and the face. BRIEF DESCRIPTION OF THE DRAWINGS

The present invention is further described in detail below with reference to the drawings and embodiments:

FIG. 1 is a schematic structural diagram of a casing of the present invention;

2 is a schematic structural diagram of an outer casing of the present invention;

FIG. 3 is an assembly schematic diagram of the present invention;

5 is a sectional view of an intake valve and a diaphragm thereof according to the present invention;

6 is a cross-sectional view of an outlet valve and a diaphragm thereof according to the present invention;

7 is a schematic view of a diaphragm structure of the present invention;

The bionic intelligent mask device according to the present invention, as shown in FIG. 1, includes a housing 1, and the contact surface between the housing 1 and the human face is adapted to the shape of the human face, and a breathing chamber 2 is formed between the housing 1 and the face, and the housing 1 Soft and elastic items such as rubber and silicone are mounted on the contact with the face, so that the contact position between the case and the face is sealed as much as possible, and an inhalation valve is opened on the case 1 at a position corresponding to the direction in which the user inhales and exhales. 3 and the exhaust valve 4, the intake valve 3, the exhaust valve 4 is equipped with one or more diaphragms 5 made of elastic material, the diaphragm 5 has two or more than three cuts 6, the cuts 6 are The divergent incision is limited by the elasticity of the material This cut cannot be made too large, and multiple diaphragms 5 can be installed on the suction valve 3 and the outlet valve 4. As shown in FIG. 1, the casing 1 is equipped with six diaphragms 5, and the diaphragm 5 of the suction valve It protrudes toward the inside of the housing, and the diaphragm of the outlet valve protrudes outward from the housing, and the cutout 6 or divergent cutout is on the protrusion, as shown in Figs. Not only the elastic force, but also the tension of the diaphragm 5 makes the opening and closing more smooth and labor-saving. The suction valve 3 is located near the face and nose, and the outlet valve 4 is located below the suction valve. The outlet valve 4 has an inclination toward the nose to ensure smoother breathing. When using the bionic smart mask device of the present invention, the user only needs to place a filtering item in the casing according to the purpose of use, which can be used as a mask, which is convenient for the user to use in different occasions. When the filtering item is polluted, it is also convenient to clean And replaced.
