The chemical oxygen respirator 21 can be arranged on the life-saving floating bag 11; the working principle of the chemical oxygen respirator 21 is a carbon-oxygen exchange type respirator, namely, oxygen is generated by the chemical reaction of an oxygen generating agent mainly composed of potassium superoxide with carbon dioxide and water vapor in the exhaled air of a human body, isolated internal circulation respiratory protection is provided for a user, and the chemical oxygen respirator 21 can provide normal underwater breathing for at least 30 minutes. Obviously, the length of time of supply is related to the amount of oxygen generating agent used.

As shown in fig. 2 and 3, the adaptor 23 may include an adaptor housing 231, a rotating body 232, and a knob 233; a cylindrical installation space is arranged in the adapter shell 231, and a first breathing port 2311 and a second breathing port 2312 which are communicated with the installation space are respectively arranged at two sides of the adapter shell 231; the first breathing port 2311 is communicated with the action end of the chemical oxygen respirator 21; the second breathing port 2312 is communicated with the mouthpiece 22; the rotating body 232 is cylindrical, one end of the rotating body 232 is sleeved in the installation space, and the other end of the rotating body 232 extends out of the adapter shell 231 and is fixedly connected with the knob 233; the knob 233 is used to rotate the rotating body 232. A through hole is formed in the middle of the rotating body 23, and when the rotating body 23 rotates to the first position, the first breathing port 2311 and the second breathing port 2312 can be communicated through the through hole; when the rotating body 23 rotates to the second position, the through hole is no longer communicated with the first breathing port 2311 and the second breathing port 2312, so that the closing is realized; the mouthpiece 22 is mounted at the second breathing opening 2312. The mouthpiece 22 is primarily used to provide a breathing port to the user.

The specific structure of the rotating body 232 is as follows: one end of the rotating body 232 is sequentially divided into a first side, a second side, a third side and a fourth side along the circumferential direction, the first side of the rotating body 232 is provided with a third breathing port 2321 corresponding to the first breathing port 2311, and the third side of the rotating body 232 is provided with a second breathing port 2312 corresponding to the second breathing port. That is, the third breathing port 2321 and the fourth breathing port 2322 together form a through hole provided in the middle of the rotation body 23.

When the user does not need to start the respiratory protection function or finish the floating and diving activities, the knob 233 can be rotated to the closed state, and then the respiratory channel is closed, so that the moisture can be effectively prevented from flowing into the chemical oxygen respirator 21, and further the severe reaction between the inflowing moisture and the oxygen generating agent can be avoided. The operation is very simple, and the training operation does not need to take time.

It is understood that the lifesaving floating bag 11 is a separate structure, that is, the lifesaving floating bag 11 is not communicated with the chemical oxygen respirator 21, and only the chemical oxygen respirator 21 is installed outside the lifesaving floating bag 11. Therefore, if a user encounters an accident that the ship turns over and sinks and is trapped in the space of the ship body, the snorkel can not only provide buoyancy support for the user in water, but also provide breathing protection for the user for a certain time, so that the user has a larger chance to escape from the ship body to a safe area during self rescue. Alternatively, the time to wait for rescue can be increased for the user. Simultaneously, this float and dive respirator has less volume for air respirator under water, also is convenient for professional diver to carry for subsequent use when rescuing to the trapped personnel who finds in the search and rescue are provided for, make search and rescue personnel need not to sacrifice the diving equipment of oneself and give the trapped personnel, thereby avoid leading to search and rescue personnel not breathing protection and drowned in the dive.
