[0039] Specifically, Figure 1 , Figure 4 As shown, when in use, by pulling a sealing piece 19, the sealing piece 19 is moved away from the life jacket body 1 under the action of the Velcro 20, so that the staff can take out the floating block 16 inside the life jacket body 1 for cleaning, maintenance or replacement, and the removal of the floating block 16 does not affect the use of the life jacket body 1.

[0040] Working principle: When the utility model is used, first, when the user enters the water area for rescue, the filter paper roll 1301 contacts the water and softens, thereby contacting the limit of the pull rope 1303, so that the tension on the reset spring 1306 disappears and resets, and the reset spring 1306 resets while pushing the piston 1307 to move horizontally inside the cylinder 1305, thereby squeezing the air inside the cylinder 1305, so that the air inside the cylinder 1305 is introduced into the inside of the connecting pipe 4 through the air outlet 1308, so that the air inside the connecting pipe 4 enters the inside of the airbag 15, and the airbag 15 is inflated through the above operation, so that the airbag 15 expands to increase the buoyancy of the life jacket body 1, and with the cooperation of the floating block 16, it can ensure that the drowning person can float to the surface safely, so as to facilitate rescue by rescue personnel;

[0041] Then, the sealing piece 19 is pulled to separate the Velcro 20 on the sealing piece 19 from the Velcro 20 on the life jacket body 1. In the process of continuously pulling the sealing piece 19, the sealing piece 19 is kept away from the life jacket body 1. The above operation makes it easy for the staff to take out the floating blocks 16 inside the front and back surfaces of the life jacket body 1 so as to clean, repair or replace it. After the floating blocks 16 are taken out, the life jacket body 1 can be used as a safety harness, so that the rescue personnel can quickly and safely rescue the person who falls into the water through the equipment of the sling or helicopter, thereby improving their rescue efficiency.
