Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] See also Figure 1-3 A fire-fighting dual-purpose life jacket in this embodiment includes a life jacket 1, on which an air bag 2 for floating and a reflective strip 3 for warning are installed, and the life jacket 1 also has a whistle for the wearer to call for help;

[0022] The life jacket 1 also includes a filter device installed on the surface of the life jacket 1. A connecting belt 4 is sewn on the outside of the life jacket 1. A bag tube 5 is integrally extended outside the connecting belt 4. The filter device is installed on the surface of the life jacket 1 through the bag tube 5.

[0023] In this embodiment, the filtering device includes a mounting tube 6 slidably connected to the bag tube 5 and a filter bag 15 built into the mounting tube 6, wherein the mounting tube 6 is a plastic tube that can block the infiltration of external water, one end of the mounting tube 6 is open, and a sealing piece is installed at the opening of the mounting tube 6 for closing the mounting tube 6.

[0024] It should be noted that the sealing member includes a threaded ring 9 fixedly mounted on the end of the mounting tube 6 and a plunger 10 threadedly connected to the threaded ring 9 . A pull ring 11 is also fixedly mounted on the outside of the plunger 10 to facilitate the rotation of the plunger 10 and the pulling of the plunger 10 .

[0025] In a specific implementation, by rotating the pull ring 11 , the pull ring 11 can drive the fixedly connected plunger 10 to rotate, so that the plunger 10 is removed from the end of the mounting tube 6 .

[0026] In this embodiment, an extension column 12 is fixedly mounted on one end of the plunger 10, a connecting pipe 13 is rotatably mounted on one end of the extension column 12, one end of the filter bag 15 is connected to the connecting pipe 13, and the other end is fixed to the inner wall of the mounting pipe 6 by a flange;

[0027] Furthermore, a mouthpiece 14 is integrally protruded on the connecting tube 13 , and the mouthpiece 14 is connected to one end of the connecting tube 13 , so that air can be sucked toward the inside of the filter bag 15 through the mouthpiece 14 .

[0028] In a specific implementation, by sucking air from the mouthpiece 14 , the filter bag 15 immersed in the water body can filter the water body to a certain extent. At this time, the filtered impurities adhere to the outside of the filter bag 15 , and the filtered water is sucked out from the mouthpiece 14 through the connecting pipe 13 .
