Referring to fig. 11 and 12, specifically, the water sealing valve 3b includes a valve body 31b, a fixed valve core seat 32b, a counterweight magnetic float 33b, a water sealing ball head 34b, a water sealing rubber sleeve 35b, a valve ring 36b, a gasket 37b, a one-way valve plate 38b, a valve plate seat 381b, and a pipe interface 39b. The water sealing rubber sleeve 35b, the valve ring 36b, the gasket 37b, the valve plate seat 381b and the one-way valve plate 38b are sequentially arranged in the pipe interface 39b, and the other end of the pipe interface 39b is communicated with one of the first air inlet 33a, the second air inlet 34a and the third air inlet 35a of the five-way air chamber 3 a. The water sealing ball head 34b is mounted at the upper end of the counterweight magnetic float 33b, the counterweight magnetic float 33b is accommodated in the valve body 31b, the fixed valve core seat 32b is mounted at the bottom end of the valve body 31b and forms mutual repulsion with the counterweight magnetic float 33b, and the top end of the valve body 31b is fixedly connected with the pipeline interface 39b. The valve body 31b has a hollow structure, and is used for air intake and water intake.

Referring to fig. 9-12, the water sealing valve 3b works according to the following principle: when the device is on water, the water sealing valve 3b is in a vertical upward state, wherein the counterweight magnetic floater 33b is in a suspension state under the self gravity and the repulsive force of the fixed valve core seat 32b in the valve body 31b, and at the moment, air can enter the five-way air chamber 3a through the valve body 31b and the pipeline interface 39b for ventilation of a user. As the user sinks under the water, when the water sealing valve 3b enters under the water, buoyancy is generated in the water sealing valve 3b, the counterweight magnetic floater 33b receives upward buoyancy and the repulsive force of the fixed valve core seat 32b is larger than self gravity, and moves upwards, and drives the air inlet hole which is propped against the water sealing rubber sleeve 35b by the water sealing ball head 34b to block air and water flow into the five-way air chamber 3a, so that the situation that the user chokes water is prevented, when the user enters the water briefly, the helmet body 1 can be pulled out of the water rapidly through the buoyancy of the user, and then the counterweight magnetic floater 33b of the water sealing valve 3b only receives self gravity and the repulsive force of the fixed valve core seat 32b to move downwards after losing the buoyancy of the water, so that the air inlet is opened. Wherein, the axis of the other water sealing valve 3b is in a horizontal state, at this time, the gravity or buoyancy of the counterweight magnetic floater 33b is balanced by the inner wall of the valve body 31b, and the repulsive force from the fixed valve core seat 32b directly pushes the counterweight magnetic floater 33b and the water sealing ball head 34b to seal the air inlet; the axis of the other water sealing valve 3b is vertically downward, the self gravity of the counterweight magnetic float 33b and the repulsive force of the fixed valve core seat 32b are larger than the buoyancy, and the counterweight magnetic float 33b and the water sealing ball head 34b are pushed to seal the air inlet. In summary, the invention adopts 3 water sealing valves 3b arranged in different directions to ensure that swimming beginners can not be influenced by choking water when in basic moving states of head top up, face up and face down in water, wherein one water sealing valve 3b is vertically upwards in the axial direction in any direction, the closing and opening of an air inlet can be controlled, and the closing states of the other two water sealing valves 3b are controlled.

When a beginner moves in water, once the head is sunk due to a certain action, the water sealing valve 3b arranged at the top of the helmet body 1 can be closed when meeting water, so that breath-holding and choking prevention are realized; then, because the water surface is higher than the normal 'waterline', the volume of the body and the water inlet part of the equipment is increased, the buoyancy generated by the water drainage exceeds the gravity of the human body, and the action of the buoyancy can quickly offset the sinking energy of the body, so that the body returns to a naturally floating position; then the water sealing valve 3b is automatically opened again, so that the air exchange between the human body and the outside is ensured. Due to the protection of the respiratory tract, a beginner can submerge the head in water in a large amount; and because the water line is naturally aligned to the horizontal plane, the brain bag in the drilling water naturally floats out of the water surface under the action of the floating force. Therefore, beginners can release the free movement of limbs without worry, so that the beginners can quickly find out the movement of the human body in water, and once the movement method for keeping the head and even the chest exposed out of the water is mastered, the beginners can take off the helmet for free exercise.

In this embodiment, the water sealing valves 3b respectively connected to the first air inlet 33a, the second air inlet 34a, and the third air inlet 35a are respectively disposed in the upward, forward, and backward directions, so as to ensure that the user can breathe freely in the supine, prone, and suspended in the water and prevent choking.

Further, safety belts 4 are riveted on two sides of the lower end of the helmet body 1 respectively, and the safety belts 4 on two sides can be connected and the tightness degree can be adjusted.

Furthermore, the opening of the installation cavity 1b at the upper end of the helmet body 1 is connected with a top cover 1d in a buckling manner, and a vent hole 1e is formed in the top cover 1d, so that the water sealing valve 3b and the waterproof air outlet 3c can exchange with the outside air.

Referring to fig. 5, further, a chignon hole is formed at the rear end of the helmet body 1 and is communicated with the wearing cavity 1a, and a chignon cover 1f is connected to the chignon hole in a snap-fit manner.

Variations and modifications to the above would be obvious to persons skilled in the art to which the invention pertains from the foregoing description and teachings. Therefore, the invention is not limited to the specific embodiments disclosed and described above, but some modifications and changes of the invention should be also included in the scope of the claims of the invention.
