When drinking water is needed, the suction nozzle 23 on the bottle cap 2 needs to be held by a mouth for sucking air, at the moment, air in the suction nozzle 23 and the connecting pipe 22 of the bottle cap 2 is sucked out, at the moment, the through hole 21 is in a vacuum state, at the moment, the atmospheric pressure outside the bottle body 1 presses the air vent plug 28 through the first air inlet hole 25 of the bottle cap 2, so that the air vent plug 28 moves towards the vent hole 26, after the air vent plug 28 moves for a certain distance, the second air inlet hole 27 on the bottle cap 2 is opened, at the moment, the inside and the outside of the water bottle are communicated, and the air outside the water bottle enters the water bottle. At this time, because the through hole 21 is vacuum and the air pressure in the water bottle is equal to the atmospheric pressure outside the water bottle, at this time, the valve core 42 in the check valve assembly 4 is forced to move towards the suction nozzle 23 due to the pressure difference, at this time, the second return spring 46 in the check valve assembly 4 is forced to deform and contract, and when the valve core 42 drives the second sealing ring 45 to move to be not in contact with the sealing part 412, the check valve assembly 4 is opened, at this time, the water in the bottle flows through the check valve assembly 4 from the suction pipe 3, and then enters the mouth of the user through the suction nozzle 23 on the bottle cap 2.
When the user drinks water, the suction nozzle pipe 23 on the bottle cap 2 is released, atmospheric pressure enters the suction nozzle pipe 23 and the through hole 21 of the bottle cap 2, the air pressure at both ends of the air hole plug 28 is the same, the air hole plug 28 returns to the original position under the elastic force of the first return spring 29, the second air hole 27 is closed, the air pressure at both sides of the check valve assembly 4 is balanced, and the second return spring 46 in the check valve assembly 4 pushes the valve core 42 to enable the second sealing ring 45 to be contacted with the sealing part 412 again and generate extrusion, so that the check valve assembly 4 returns to the closed state. At this time, the water bottle returns to the sealed state before drinking water.
