[0026] like Figures 1 to 4 As shown, an embodiment provided by the utility model: a drowning prevention device is proposed, a first tensioning belt 101 and a second tensioning belt 102 are provided on both sides of the head cover 1, the breathing mask 3 and the eyepiece 9 are respectively installed on the head cover 1 to cover the wearer's mouth, nose and eyes, a top breathing channel 11 is installed above the head cover 1, and a water-absorbing resin 1101 is arranged inside the breathing mask 3. The top breathing channel 11 is connected to the first inhalation pipe 2 and the first exhalation pipe 8. In addition, the breathing mask 3 is connected to the swimming ring type airbag 5 below through the second inhalation pipe 4 and the second exhalation pipe 7. The first automatic oxygenation device 6 and the second automatic oxygenation device 10 are installed on the bottom side of the swimming ring type airbag 5, and a pair of shoulder straps 501 are symmetrically installed on the top. A water-sensitive alarm device 12 is installed on the top of the head cover 1.

[0027] In this embodiment, specifically: a breathing hole 301 is provided on the breathing mask 3, and the person who falls into the water can open the sealing cover to breathe air after surfacing.

[0028] In this embodiment, specifically, a breathing mask sealing rubber pad 302 and an eyepiece sealing rubber pad 901 for local sealing are installed on the breathing mask 3 and the eyepiece 9.

[0029] In this embodiment, specifically: a first one-way valve 201 is provided inside the first intake pipe 2, a second one-way valve 401 is provided inside the second intake pipe 4, and an air stop clamp 402 is provided on the second intake pipe 4, which is used to block the continued leakage of oxygen in the swimming ring-type airbag 5 after the person who falls into the water surfaces, so that the person can maintain buoyancy for a long time; a third one-way valve 801 is provided inside the first exhalation pipe 8, and a fourth one-way valve 701 is provided inside the second exhalation pipe 7.

[0030] In this embodiment, specifically: the first automatic oxygen filling device 6 and the second automatic oxygen filling device 10 are fixed to the bottom side of the swimming ring type airbag 5 by using the first fixing bag 601 and the second fixing bag 1001 respectively. After the wearer falls into the water, the first compressed oxygen cylinder 602 and the second compressed oxygen cylinder 1002 quickly inflate the swimming ring type airbag 5, which not only increases the buoyancy of the swimming ring type airbag 5 and quickly drives the drowning person to the surface, but also provides the drowning person with sufficient oxygen to maintain breathing through the second suction pipe 4. The first water-sensitive element trigger device 603 and the second water-sensitive element trigger device 1003 are used as the opening device of the compressed oxygen cylinders, which can ensure rapid response and reliable operation.

[0031] In this embodiment, specifically: to ensure the sealing effect, the internal cavity of the top breathing channel 11 is isolated from the internal cavity of the headgear 1, and the partition 1102 is used to separate the inhalation side and the exhalation side of the top breathing channel 11 to ensure smooth breathing. The water-absorbing resin 1101 provided inside the top breathing channel 11 is double-layered, which is used to keep the top breathing channel 11 open when the anti-drowning device is in the standby state, providing the wearer with air required for breathing. When the wearer falls into the water, water is quickly absorbed to seal the top breathing channel 11, and the wearer inhales oxygen from the swimming ring-type airbag 5 to maintain basic breathing for a period of time.

[0032] In this embodiment, specifically: the water-sensitive alarm device 12 integrates a water-sensitive element and a battery pack, and the main working components include an alarm light 1201 and a voice reminder module 1202, which are triggered to turn on after being immersed in water. The alarm light 1201 is installed on the water-sensitive alarm device 12, and is used to send a distress alarm light signal. The voice reminder module 1202 is installed on the side of the headgear 1 close to the wearer's ear, and is used to promptly remind the person who falls into the water to stay calm and provide guidance on self-rescue measures.

[0033] Working principle: When wearing the device, the first tensioning belt 101 and the second tensioning belt 102 need to be fastened to prevent the headgear from falling off. The sealing pads provided on the breathing mask 3 and the eyepiece 9 will fit tightly against the wearer's face to keep the local space sealed. At this time, the water-absorbing resin 1101 is in a dry state, the top breathing channel 11 above the headgear 1 is in an open state, the breathing hole 301 provided on the breathing mask 3 is in a closed state, the swimming ring-type airbag is in an airless state, and the wearer breathes through the breathing mask 3, the first inhalation tube 2, the first exhalation tube 8, and the top breathing channel 11; when the wearer accidentally falls into the water, the water-sensitive element triggering devices 603 and 1003 of the first automatic oxygen filling device 6 and the second automatic oxygen filling device 10 will be triggered, and the thimble in the device will puncture the first compressed oxygen cylinder 602 and the second compressed oxygen cylinder 10 The seal of 02 allows compressed oxygen to enter the swimming ring type airbag 5, increasing its buoyancy and driving the person who falls into the water to float up. At the same time, the water-absorbing resin 1101 will quickly absorb water to seal the top breathing channel 11. The person who falls into the water can inhale oxygen from the swimming ring type airbag 5 through the second inhalation tube 4 and the second exhalation tube 7 to maintain breathing, avoiding the risk of the person who falls into the water choking; when the wearer falls into the water, the submerged water-sensitive alarm device 12 will trigger the switch, causing the alarm light 1201 to emit a distress light signal and use the voice reminder module 1202 to remind the person who falls into the water to stay calm and provide them with key self-rescue measures in the water. In addition, it reminds the person who falls into the water to close the air stop clamp 402 in time after surfacing, and open the breathing hole 301 on the breathing mask 3 to breathe natural air, so that the swimming ring type airbag 5 maintains the oxygen content and buoyancy, and strives for a longer rescue time.
