Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to FIGS. 1-3 , the present invention provides a technical solution: a fire-fighting first aid breathing mask, comprising a breathing mask main body 1 , an oxygen port 7 is connected inside the breathing mask main body 1 , and the oxygen port 7 is internally connected with oxygen Tank 9, both sides of the front end of the main body 1 of the breathing mask are connected to the limit belts 6, and the limiter soft plate 10 is installed between the limit belts 6. This structure enables the limit belts 6 to pass through the limit belts 6 on both sides and the breathing mask. The main body 1 is connected, the limit belt 6 and the head cloth belt 11 are made of elastic belts, and the width of the head cloth belt 11 is not less than 2CM. This structure allows the user to easily stretch the limit belt 6 and the head cloth belt. 11. Make the limit belt 6 and the headband 11 at a suitable length, and the headband 11 is wider, which can have a larger contact area with the wearer's head, making the wearer more comfortable, and the limit is soft. The oxygen tank 9 is connected above the board 10, and the axis of the oxygen tank 9 is coincident with the vertical bisector of the limiting soft board 10. This structure enables the bottom of the oxygen tank 9 to be received by the limiting soft board 10, so that the oxygen tank 9 will not easily The oxygen port 7 is internally connected with a sealing ring 8, and the sealing ring 8 is made of elastic rubber, and the sealing ring 8 is internally connected with an oxygen tank 9. This structure enables the top of the oxygen tank 9 to be sealed by the elastic rubber sealing ring 8. It is stuck and will not fall easily. An air port 2 is connected to the front side of the main body 1 of the respirator, and a filter element 4 is installed inside the air port 2. A sealing end cover 3 is fitted on the outside of the air port 2, and the bottom of the sealing end cover 3 is connected with a The connecting rope 5 is installed with the main body 1 of the respirator outside the connecting rope 5.
