Detailed Description

The invention is described in further detail below with reference to figures 1-11.

A one-way respirator capable of being used in a protective mask comprises a front piece 1 abutted to the inner side face of the mask and a rear piece 2 contacted with the skin of the face of a wearer, wherein the front piece 1 and the rear piece 2 are injection-molded parts, an air flow cavity is formed in a respirator main body formed after the front piece 1 and the rear piece 2 are installed, an installation opening 001 is formed in the top end of the respirator main body, exhaust ports 003 are formed in two ends, close to the cheeks of the wearer, of the respirator main body respectively, the exhaust ports 003 are duckbill flat ports, a film strip A101 is arranged on the front piece 1, a film strip B201 is arranged on the rear piece 2, close to the exhaust ports 003, adjacent film strips A101 and film strip B201 are mutually abutted and closed, an air suction port 002 is formed in the middle of the front end of the front piece 1, a one-way membrane 3 which is opened inwards when air is sucked is arranged on the air suction port 002, and the installation opening 001, the air suction port 002 and the exhaust ports 003 are respectively communicated with the air flow cavity. In this embodiment, the soft membrane strip a 101 and the soft membrane strip B201 are respectively formed by integrally molding the front sheet 1 and the back sheet 2, the widths of the soft membrane strip a 101 and the soft membrane strip B201 are respectively 2-3mm, and the soft membrane strip a 101 and the soft membrane strip B201 can also be fixed by adopting other existing installation methods. Because the existing mask is universal, the mask has quite different face shape adaptability to different people, and the contraction strips on the two sides of the mask are easy to bulge due to the material problem, the air suction port 002 of the respirator is arranged in the middle of the front end of the mask, so that the sucked air can be effectively filtered by the interlayer of the mask, and the potential hazard caused by the fact that the mask is not tightly closed is well solved.

Specifically, as shown in fig. 4, 6 and 7, in this embodiment, the inner side surface of the front panel 1 is provided with a clamping protrusion 102, the inner side surface of the back panel 2 is provided with a clamping groove 202, and each clamping protrusion 102 is clamped with a corresponding clamping groove 202, so that the front panel 1 and the back panel 2 are joined to form the respirator body. The matched arrangement of the clamping protrusions 102 and the clamping grooves 202 facilitates the front sheet 1 and the back sheet 2 to be jointed to form the respirator body, and the assembly and disassembly are easy.

Specifically, as shown in fig. 2, the mounting opening 001 in this embodiment is a circular opening formed by correspondingly closing a semicircular groove a formed in the front sheet 1 and a semicircular groove B formed in the rear sheet 2; installing port 001 has two, and equal joint has one to touch nose hose 4 on every installing port, touches nose hose 4 and adopts the silica gel material to make. As shown in fig. 8 and 9, the upper end opening of each nose-touching hose 4 is eccentric, and the two nose-touching hoses 4 are symmetrically arranged, and can be adjusted by twisting according to the needs of a user so as to be suitable for most people to wear; every lower part of touching nose hose 4 is equipped with the ring groove 401 that sets up with the cooperation of the installing port 001 that corresponds, will touch nose hose 4 card on the installing port 001 that corresponds through this ring groove 401.

Specifically, in the present embodiment, the air inlet 002 is a square opening, and the width of the air inlet 002 in the left-right direction is larger than the height in the up-down direction.

In one specific embodiment, as shown in fig. 10, each air inlet 002 is provided with a unidirectional diaphragm 3 therein, the top of the inner side surface of each air inlet 002 is provided with a unidirectional diaphragm clamping groove a, the upper end of the unidirectional diaphragm 3 is inserted into the corresponding unidirectional diaphragm clamping groove a for fixing, and the lower end is a free end.

In another specific embodiment, as shown in fig. 11, two unidirectional diaphragms 3 are respectively disposed in each air inlet 002, a unidirectional diaphragm slot B is respectively disposed at the top and the bottom of the inner side of each air inlet 002, one end of each unidirectional diaphragm 3 is respectively inserted into a corresponding unidirectional diaphragm slot B for fixing, the other end is a free end, and the free end of the unidirectional diaphragm 3 located on the upper side is covered on the front side of the free end of the unidirectional diaphragm 3 located on the lower side.

The working principle is as follows:

when in use, the assembled mask is arranged on the inner side of the mask and pressed on the inner side by the mask, the front side surface of the front piece 1 abuts against the inner side surface of the mask, and the back piece 2 is contacted with the face skin of a wearer. When air is sucked, air enters from the air suction port 002 through the mask, and the one-way membrane 3 is opened inwards; the inhaled air is inhaled by a wearer through the air flowing cavity and the nose touching hose 4 arranged from the mounting opening 001, and the inhalation amount of the air in the inhalation state is naturally adjusted by the breathing speed or the inhalation force; after inspiration is finished, the one-way diaphragm 3 automatically falls and closes, and is further closed tightly in the expiration state. The exhaled air enters the air flowing cavity from the nose touching hose 4, the soft membrane strips A101 and the soft membrane strips B201 on the two sides of the respirator body are naturally opened, the exhaled air naturally escapes to the exhaust ports 003 close to the two sides of the cheek, and the front end of the mask is not wet due to the fact that the exhaled wet air escapes from the exhaust ports 003 on the two sides, so that the situation that the inhaled amount of fresh air is blocked is avoided, and the time effect of protection is prolonged.
