The venthole 19 be equipped with it is multiple, be uniformly distributed centered on the axle center of through-hole 13.
The top for importing head 14 is spherical cambered surface, and the maximum gauge for importing head 14 is greater than the internal diameter of through-hole 13.
The top surface of the end plate is equipped with bulge loop B18, the internal diameter of the bulge loop B18 and the maximum gauge for importing head 14
Match.
To having and the matched pipe sleeve 7 of standpipe 8, the side of the pipe sleeve 7 in the cup lid 2, positioned at 2 roof center of cup lid
Wall is equipped with multiple holes 24 positioned at the junction of pipe sleeve 7 and cup lid 2, and described hole 24 is uniformly divided centered on the axle center of pipe sleeve 7
Cloth, in described hole 24, the lower edge of described hole 24 be equipped with elastic slice 10, the inner sidewall of the elastic slice 10, positioned at top sides along setting
There is horizontal raised line 12, the horizontal raised line 12 is matched with the clamping of annular groove 11 set by 8 lateral wall of standpipe.
8 lateral wall of standpipe is successively arranged bulge loop C17 and bulge loop D20, the sealing ring positioned at bottom position upwards
4 inner sidewall and bulge loop C17 is clamped, and the top surface of sealing ring 4 is contacted with the limit of the bottom surface of bulge loop D20.
The edge of the bulge loop D20 be equipped with notch 23, the notch 23 be equipped with it is multiple, centered on the axle center of standpipe 8
Even distribution.
Bulge loop E6 is provided inwardly on the inside of the rim of a cup of the cup body 1, the sealing ring 4 and bulge loop E6 cooperation seals.
Glass mouth 5 is fixed on the inside of the rim of a cup of the cup body 1, positioned at the top of bulge loop E6.
It is equipped with external screw thread 21 on the outside of the rim of a cup of the cup body 1, the inner sidewall of the cup lid 2 corresponds to external screw thread 21 and is equipped with
The internal screw thread 22 matched.
The valve block 9, the material for importing head 14, boss and valve block 15 are silica gel or rubber.
When the utility model uses, since cup lid 2 and cup body 1 are only consolidated by internal screw thread 22 and external screw thread 21
It is fixed, so extraneous atmosphere can be by being connected to, but due to cup in gap between external screw thread 21 and internal screw thread 22 and cup lid 2
The bulge loop E26 of sealing ring 4 set by lid 2 and cup body 1, which is sealed, to be cooperated, thus the air in the cup lid 2 being connected to ambient atmosphere without
Method passes through sealing ring 4 and contacts with the water in the cup body 1 for being located at 4 lower section of sealing ring, makees to play heat preservation to the water in cup body 1
With；After the vapor in cup body 1, in the air of ullage is condensed into liquid water, the pressure in cup body 1 will lead to
Less than external atmosphere pressure, when draught head is sufficiently large, valve block 15 can be made to be inhaled downwards, overcome the elastic force of valve block 9, drive
Valve block 9 moves down, so that boss be made to separate from groove, and then enters the air in cup lid 2 by venthole 19 and is located at
In the cup body 1 of 4 lower section of sealing ring, so that the air pressure subtractive of air pressure and ambient atmosphere in the cup body 1 of 4 lower section of sealing ring
It is small, when the air pressure in the cup body 1 of 4 lower section of sealing ring is equal with external atmosphere pressure, acted in the elastic-restoring force of valve block 9
Under, so that valve block 9 is returned back to initial state: i.e. boss is bonded with groove, is caused big close with the external world in the cup body 1 of 4 lower section of sealing ring
It is exhausted to seal air bound；It is seldom into the air capacity in the cup body 1 of 4 lower section of sealing ring since venthole 19 is smaller, so will not be to cup
The temperature of water in body 1 plays cooling effect.
In addition, cup lid 2 for cup body 1 with respect to moving up, so leading when needing to drink water, open cup lid 2
The volume in the space in fine and close 4 lower section of seal and cup body 1 between liquid level increases, and since the sealing of sealing ring 4 and cup body 1 is made
With, and the gas flow in 4 lower section of sealing ring and cup body 1 between liquid level does not increase, and then leads to 4 lower section of sealing ring and cup body 1
Air pressure between interior liquid level reduces, is lower than external atmosphere pressure；When draught head is sufficiently large, valve block 15 can be made downward
It inhales, overcomes the elastic force of valve block 9, band movable valve block 9 to move down, so that boss be made to separate from groove, and then make the sky in cup lid 2
Gas is entered in the cup body 1 of 4 lower section of sealing ring by venthole 19, so that the gas in the cup body 1 of 4 lower section of sealing ring
The draught head of pressure and ambient atmosphere reduces, when the air pressure in the cup body 1 of 4 lower section of sealing ring is equal with external atmosphere pressure,
Under the elastic-restoring force effect of valve block 9, valve block 9 is made to return back to initial state: therefore during open cup cover, valve block 9
This above process is constantly repeated, so that the air pressure in the cup body 1 of 4 lower section of sealing ring is constantly balanced with external atmosphere pressure,
So that opening will not cause the opening of cup lid 2 hard, difficult because of suction function when being changed, reduces cup lid and beat
The resistance opened, the convenience for improving cup lid opening.
In addition, due to being limited between standpipe 8 and pipe sleeve 7 there is no circumferential, so being between standpipe 8 and pipe sleeve 7 can be around
The axis rotation of standpipe 8；Therefore when cup lid 2 is unscrewed or screwed by rotating cup lid 2, due to being sheathed on
Under the action of stiction, sealing ring 4 between the sealing ring 4 and cup body 1 of standpipe 8 and the stiction between standpipe 8, work as cup
Lid 2 rotates with respect to cup body 1, and the standpipe 8 for being arranged with sealing ring 4 is then circumferentially keeping relatively fixed with cup body 1, and then makes to stand
It is relatively rotated between pipe 8 and the pipe sleeve 7 of cup lid 2；That is cup lid 2 is placed on the sealing of standpipe 8 when being unscrewed or being screwed
Only has the opposite force of sliding friction of up and down direction between circle 4 and cup body 1, without the circumferential sliding friction of previous existing rotation
Power, therefore the convenience that further reduced the resistance of cup lid opening, improve cup lid opening.
When the utility model carries out unpicking and washing replacement, first cup lid 2 is separated with cup body 1, then by sealing ring 4 from standpipe
It is removed on 8；Standpipe is downwardly drawn out using finger by pipe sleeve 7 by notch 23 again, then again pulls out valve block 9 downwards from through-hole 13
Out；When installation, successively installed according to above-mentioned reverse order.
