[0002] Generally, water sports have always been popular among a large number of sports enthusiasts, as well as some other activities near the water surface, on the shore, or on the bridge. While doing sports or living, safety must be ensured and awareness of prevention should be possessed. Especially for preventing drowning, one needs to be vigilant against accidents at all times.

[0003] Under the existing technology, life jackets have a simple structure and mostly can only provide barely sufficient buoyancy, unable to achieve effective rescue. There are existing relatively complex rescue devices, but due to inconvenient carrying, it is also difficult to meet the requirements during use; and they may not be assembled and put into use in advance before an accident occurs.

[0012] The battery pack is electrically connected to the controller and the water immersion sensor respectively;

[0013] The power switch is electrically connected to the controller;

[0014] The controller is configured to be connected to the solenoid valve. The gas flow input end of the solenoid valve is configured with a quick connector for a gas cylinder, and the quick connector for the gas cylinder is connected to a high-pressure CO2 gas cylinder. A gas flow check valve is fixedly connected to the gas flow output end of the solenoid valve, and the gas flow output end of the solenoid valve is communicated with the front chest airbag and / or the rear chest airbag;

[0015] The electric control inflation pack is fixedly connected to the front body and / or the rear body.

[0016] Furthermore: The front chest airbag is provided with a front chest airbag inflation connecting pipe communicated therewith, and a front chest inflation check valve is arranged in the front chest airbag inflation connecting pipe; the front chest airbag inflation connecting pipe is cooperatively connected to the gas flow output end of the solenoid valve;

[0018] Furthermore: The external interface of the front chest airbag inflation connecting pipe is set as a front-mounted high-pressure gas cylinder emergency quick connector;

[0019] The external interface of the rear chest airbag inflation connecting pipe is set as a rear-mounted high-pressure gas cylinder emergency quick connector.

[0020] Furthermore: The electric control inflation pack is fixedly connected to the outer surface of the front body below the front chest airbag, and the fixed connection is adopted by bonding, sewing, or in-layer embedding.

[0021] Furthermore: The electric control inflation pack is fixedly connected to the outer surface of the rear body below the rear chest airbag, and the fixed connection is adopted by bonding, sewing, or in-layer embedding.

[0022] Furthermore: The front chest airbag is configured with an overpressure protection pressure relief valve;

[0023] The rear chest airbag is configured with an overpressure protection pressure relief valve.

[0024] Furthermore: The water immersion sensor is arranged at the lower edge of the front chest airbag and the rear chest airbag.

[0025] Furthermore: The automatic life jacket is provided with a cut-resistant surface layer at least on the outer layer surface of the body where the front chest airbag and the rear chest airbag are located, and the cut-resistant surface layer is composed of high-strength high-modulus polyethylene fiber coated with glass fiber, spandex, or steel wire.

[0026] Furthermore: The overall body of the automatic life jacket adopts a T-shirt or a vest.

[0027] Furthermore: The front body of the automatic life jacket with a vest body is provided with a front opening from top to bottom, and laces are arranged at both sides of the front opening;

[0028] The front opening divides the front body airbag into two parts, one part is the left chest airbag, and the other part is the right chest airbag;

[0029] The left chest airbag and the right chest airbag are respectively connected to the rear shoulder and back airbag.

[0030] The beneficial effects of the present utility model compared with the prior art are as follows:

[0031] The automatic life jacket of the present utility model is quick and convenient to wear and connect, safe and reliable. When the power is turned on, as long as the water immersion sensor encounters water, the airbag can be automatically and quickly inflated, realizing an effective rescue for accidental falling into water and automatic opening.

[0032] It can also be worn into the water with the power off. In case of danger, the power can be manually turned on emergently to quickly inflate, realizing a temporary and active self-rescue.

[0033] The water immersion sensor of the present utility model is a sensor for detecting whether the measured range encounters water. Once water immersion occurs, a sensing signal is immediately sent to the controller. When the controller receives the connection signal of the water immersion sensor, it directly starts the solenoid valve to open, enabling the high-pressure CO2 gas cylinder to quickly inflate the front chest airbag or the rear chest airbag.

[0034] When overpressure occurs during inflation, the configured overpressure protection pressure relief valve can automatically open and close, effectively maintaining the normal pressure in the front chest airbag or the rear chest airbag.

[0035] The water immersion sensor is based on the principle of liquid conductivity, uses electrodes to detect the presence of water, and then converts it into a dry contact output by the sensor. It has two output states: normally open and normally closed.

[0036] The water immersion sensor uses the principle of liquid conductivity for detection. Normally, the two probe electrodes are insulated by air; in the immersed state, the probes conduct, and the sensor outputs a dry contact signal. When water touches the sensor probe, the main control chip accurately determines the state by calculating the magnetic field change and makes a processing. Detection objects: tap water, pure water, surface fresh water, seawater, etc.

[0037] When the front chest airbag and the rear chest airbag are connected to form a communicating vessel configuration, if a single electronically controlled inflation package is used to inflate the front and rear airbags, due to the tension of the airbag and the material, it is possible that one airbag expands greatly while the other inflates very little. Although the pressure balance can be achieved, the life-saving effect in this case is not good. Therefore, it is more preferable to separately configure electronically controlled inflation packages for the front and rear unilateral airbags respectively.

[0038] The water immersion sensor is placed below the airbag, which can open the solenoid valve and inflate the airbag at the first time when the wearing user enters the water, avoiding the head of the wearing user from being submerged in water, winning more time than before, and avoiding accidents.

[0039] The body of the utility model is made into a top form, which can be configured with daily clothing patterns, is light and beautiful, and users are happy to wear it. The previous life jackets are bulky, clumsy and cumbersome to wear. When used, they are worn like ordinary clothes, which increases the extensiveness of protection, prevents accidents in a larger range and to a greater extent, and protects people's lives.

[0040] The high-pressure CO2 gas cylinder can be configured outside the electronically controlled inflation bag, and the high-pressure CO2 gas cylinder can be directly removed for use when needed.

[0041] The front chest airbag and rear chest airbag are also equipped with an inflation pipe with a one-way valve. If the electronically controlled inflation bag fails or malfunctions in an emergency, a high-pressure CO2 cylinder can be directly connected to the front chest airbag or rear chest airbag for emergency inflation.

[0042] The outer anti-cut surface layer of the front chest airbag and the rear chest airbag of the utility model has super anti-cut performance, wear resistance and stab resistance; to a certain extent, it can effectively protect the life jacket body from being cut by sharp objects, such as stones, steel bars, sharp blades, etc., to ensure lifesaving and survival safety.

[0043] High-pressure CO2 cylinders are easy to obtain and can be kept in large quantities for backup. They are small in size, have a high gas compression rate, are easy to carry, and are safer.

[0044] The automatic life jacket of the utility model has reasonable design, simple structure, safety and reliability, convenient use and easy maintenance, and has good promotion and use value. BRIEF DESCRIPTION OF THE DRAWINGS
