A first sealing member 7 communicated with the air inlet channel 41 is connected below the air inlet channel 41 through threads, meanwhile, an air outlet cavity 44 communicated with the first air outlet channel 42 and the second air outlet channel 43 is arranged in the air inlet base 4, and a second sealing member 8 connected with the air inlet base 4 is arranged at the air outlet cavity 44. The first seal 7 and the second seal 8 are preferably made of a flexible material such as silicone rubber, which is slightly elastic.

Below the intake base 4, there are detachably connected a water bottle connection seat 9, a radially protruding intake seal ring 91 provided in a central area on the water bottle connection seat 9, and an exhaust seal ring 92 provided on an outer ring of the intake seal ring 91 and also radially protruding. When the water bottle connecting seat 9 is connected to the air inlet base 4, the outer edge of the first sealing member 7 is pressed against the inner edge of the air inlet sealing ring 91, and the outer edge of the second sealing member 8 is pressed against the inner edge of the air outlet sealing ring 92, so that the air inlet and air outlet channels are not communicated with each other.

The lower part of the air inlet base 4 is detachably connected with a nozzle connecting seat 10 through threads, the middle part of the nozzle connecting seat 10 is communicated, a detachable air inlet pipe 11 is arranged below the nozzle connecting seat, the upper end of the air inlet pipe 11 is provided with external threads, and the air inlet pipe is screwed with the internal threads at the lower end of the nozzle connecting seat 10. The outer contour of the nozzle connecting seat 10 gradually reduces from top to bottom and forms at least one section of curved surface transition; a sealing ring 16 is arranged at the joint of the air inlet pipe 11 and the nozzle connecting seat 10; the lower end of the connected air inlet pipe 11 is positioned below the horizontal center line 15 of the water bottle 3.

Meanwhile, the nozzle connecting seat 10 is provided with a containing groove 101, and a containing cavity 12 is formed between the containing groove 101 and the water bottle connecting seat 9; the outer wall of the nozzle connecting seat 10 and the inner wall of the water bottle 3 form an exhaust gap 13; the water bottle connecting seat 9 is provided with a pressure limiting valve structure 9, and the pressure limiting valve structure 9 is arranged in the accommodating cavity 12. The pressure limiting valve structure 9 includes a cylindrical body 931 with a hole formed in the upper and lower sides, a spring 932 and a plug 933 are disposed in the cylindrical body 931, and the spring 932 drives the plug 933 downward to seal the exhaust hole 934 at the lower end in a normal state.

An air inlet hole 911 is formed in the bottom of the air inlet sealing ring 91, a float valve 14 capable of moving up and down is arranged on the air inlet hole 911, a counter bore 141 and a radial small hole 142 communicated with the counter bore 141 are arranged in the float valve 14, an upper stop block 143 and a lower stop block 144 are respectively arranged at the upper end and the lower end of the float valve 14, the distance between the upper stop block 143 and the lower stop block 144 is the range that the float valve 14 can move up and down, when air is inlet, the air is downwards pushed by the float valve 14 from top to bottom, the radial small hole 142 of the float valve 14 is positioned in a cavity between the water bottle connecting seat 9 and the nozzle connecting seat 10, so that the air can enter the water bottle 3 through the air inlet pipe 11 and is fully released in liquid in the water bottle 3; when the air intake is completed, the air pressure inside the water bottle 3 pushes the float valve 14 upwards, so that the radial small holes 142 of the float valve are positioned in the cavity between the water bottle connecting seat 9 and the first sealing piece 7, namely, the air intake sealing ring 91, and at the moment, the air in the water bottle 3 cannot flow back from the float valve 14.
