It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] 1. Please refer to Figure 1-3 The present invention provides an air oxygenation type individual respirator, characterized in that it comprises a mask (1), an oxygen cylinder (4), and an oxygenation structure (3) component;

[0018] The air source of the air oxygenation type individual breathing apparatus is a mixture of ordinary air from the atmosphere and oxygen provided by the oxygenation structure (3) for breathing, so as to increase the oxygen content of the inhaled air in the oxygen-deficient area;

[0019] The oxygen-enhancing individual respirator comprises: a mask (1), a one-way valve (2), an oxygen-enhancing structure (3) assembly, an oxygen cylinder (4), a fixing buckle (5), a medium-pressure pipe (6), an integrated oxygen pressure reducer (7), a pipe joint (9A-9C), a shoulder strap (8), an adjusting nut (9), a valve plate (290), a pressure rod (301), a T-shaped piece (302), a sealing ring (303A-303F), a spring (304A-304C), an air storage chamber (305), a fixing pin (306), a pressure gauge (307), an underpressure alarm (308), a plug (309), and a switch (401).

The user puts on the mask and starts breathing. As the pressure of the inhaled air increases during breathing, the valve sheet will tilt inward. At this time, the contact on the valve sheet will push the pressure rod. When the pressure rod moves, it drives the T-piece. At this time, the seal between the gas storage chamber and the T-piece is destroyed, and the oxygen in the gas storage chamber flows out. The outflowing oxygen is inhaled The air is mixed together for the user to breathe, thereby achieving the purpose of increasing oxygen. The more air inhaled, the greater the suction force, the greater the suction force, the greater the inclination of the valve plate, the more the contact pushes the pressure rod, the more oxygen flows out, and the higher the oxygen content of the air inhaled into the mask. The valve plate is designed with a reset spring. When the user stops inhaling, the reset spring will force the valve plate to reset. During reset, the valve plate contact leaves the pressure rod, and then the T-shaped piece resets and seals, and oxygen stops flowing out.

The air storage chamber (305) is hollow in design. One end of the pressure rod (301) is installed with an adjusting nut (9) and the other end is connected to the T-shaped piece (302) by threaded connection. After the spring (304A-304C) and the T-shaped piece (302) are installed, the other end of the air storage chamber (305) is sealed with a plug (309) by threading. One end of the return spring (304A-304C) contacts the T-shaped piece (302) and the other end contacts the plug (309). A sealing ring (303A-303F) is provided between the threaded connection of the T-shaped piece (302) and the pressure rod (301). When the pressure rod (301) is pressed by the contact external force, the T-shaped piece (302) will move up and down together.

[0024] Furthermore, the entire oxygen enrichment device comprises a mask (1), an oxygen cylinder (4), 5-fixing buckle, 6-medium-pressure pipe, 7-integrated oxygen pressure reducer, a pipe joint (9A-9C), a valve plate (290), a pressure rod (301), a T-shaped piece (302), a sealing ring (303A-303F), a spring (304A-304C), an air storage chamber (305), a fixing pin (306), a pressure gauge (307), an underpressure alarm (308), a plug (309), and a switch (401). The device can be used to supplement oxygen when people in high-altitude hypoxic areas inhale air. The air inlet end of the mask (1) is provided with a position for installing the fixing buckle (5). After the fixing buckle (5) is installed, the air storage chamber (305) will not be loosened from the mask (1). The pressure gauge (307) and the underpressure alarm (308) are installed on the integrated oxygen pressure reducer (7).

[0025] Working principle and use process of the present invention: In the present embodiment of the present invention, a 3-oxygenation structure is installed, which includes a mask (1), an oxygen cylinder (4), a fixing buckle (5), a medium-pressure pipe (6), a pipe joint (9A-9C), an integrated oxygen pressure reducer (7), a valve plate (290), an air storage chamber (305), a shoulder strap (8), an adjusting nut (9), a pressure gauge (307), an underpressure alarm (308), and a switch (401), wherein the 305-air storage chamber includes; a valve plate, a pressure rod, a T-shaped piece, a sealing ring, a spring, a fixing pin, an air inlet hole, and a plug to form a whole.The installed valve sheet is connected by a fixing pin, and the sealing ring is installed on the external groove of the air storage chamber, and then the augmented structure component is installed on the air inlet of the mask through a fixing buckle thread connection. After the fixing buckle is installed, the valve sheet will move inward with the inhalation during inhalation. When the valve sheet tilts inward, the contact on the valve sheet contacts the pressure rod, thereby pushing the pressure rod and the T-shaped piece. At this time, the sealing surface between the T-shaped piece and the air storage chamber is destroyed. At this time, the oxygen in the air storage chamber will flow out from the broken sealed gap. The T-shaped piece installed in the air storage chamber is provided with a spring, and the spring serves as the reset force of the T-shaped piece. When the valve sheet contact leaves the pressure rod, the pressure rod and the T-shaped piece quickly reset the seal under the action of the pulling force of the reset spring. The t-shaped piece is installed in the gas storage chamber, wherein one end of the pressure rod passes through the transition hole of the gas storage chamber and is connected to the t-shaped piece by a threaded manner. Before the pressure rod and the t-shaped piece are connected, a sealing ring needs to be placed between them, and a part of the pressure rod is exposed outside the gas storage chamber to cooperate with the valve plate contact. When installing the valve plate, first align the valve plate with the installation hole, then put on the reset spring, and then insert the fixing pin to make the valve plate and the spring not easy to fall off. After the connection is installed, the valve plate needs to be kept flexible in opening and closing. The t-shaped piece reset spring is installed in the gas storage chamber, with one end against the t-shaped piece and the other end against the plug. After installation, the air pipe is connected. When using it, the user first wears the mask and turns on the gas cylinder switch. The air reducer will automatically reduce the pressure. When the user inhales air, the air will enter the mask from the air inlet of the mask, and the valve plate will open and tilt inward. At this time, the valve plate contact is forced to contact the adjusting nut on the pressure rod. The greater the suction force, the more the valve plate tilts, and the valve plate contact pushes the adjusting nut more. At this time, the pressure rod drives the T-piece and the sealing surface of the air storage chamber to increase. The more oxygen flows out, the higher the oxygen content of the air inhaled into the mask. When the user stops inhaling, the return spring on the valve plate will force the valve plate to reset. At this time, the valve plate contact will separate from the adjusting nut on the pressure rod, and the return spring in the air storage chamber will pull the pressure rod and the T-piece back and reset under the action of force, so that the sealing ring on the T-piece is just in line with the air storage chamber. The sealing surfaces are in contact to form a seal, and the oxygen in the air storage chamber stops escaping. One end of the pressure rod is threadedly connected to the T-piece. During installation, the pressure rod passes through the air storage chamber and is threadedly connected to the T-piece installed inside the air storage chamber. One end of the air storage chamber is also designed with an oxygen inlet, and the oxygen inlet is equipped with a trachea connected to an integrated pressure reducer. Through the coordinated work between the various components of the oxygen enrichment device, automatic oxygen enrichment of the air can be achieved when people breathe air in an oxygen-deficient environment. When the pressure in the gas cylinder is reduced, the underpressure alarm sounds an alarm to remind the user to replace the gas cylinder. When in use, first connect the entire component, put on the mask, turn on the gas cylinder switch, and then you can start using it. The respirator is designed to be portable.
