Bright embodiment also provides a kind of vacuum cup, including cup lid as above and cup body 12.
Illustrate the application method of cup lid and vacuum cup of the invention below with reference to Fig. 1 to Figure 11.
After assembling cup lid, cup lid is covered on cup body 12, and screw cup lid, cup lid is made to be sealed in the opening of cup body 12
End.Rotation pressing knob 5 makes it be changed into unlocked state by lock state, and the clamping block 41 on lock circle 4 leaves air pump at this time
The limited step 312 of outer cylinder 31 is moved to 313 position of sliding slot, and air pump inner cylinder 33, air pump outer cylinder 31 and the first sealing ring 32 are in bullet
It is moved up under the elastic force effect of spring 34.The inner wall of third cylinder 102 of first sealing ring 32 in upper cover 1 downward rubs to its
Wipe the first convex edge 331 for being close to the bottom of air pump inner cylinder 33 under the action of power, the first sealing ring 32 is by the first convex edge 331 and the
Clearance seal between three cylinders 102, the gas in pumping chamber 100 not can enter between the first convex edge 331 and the second convex edge 315
Groove.During air pump inner cylinder 33 moves up, the volume of pumping chamber 100 increases, since the gas in pumping chamber 100 is close
Envelope, therefore the pressure in pumping chamber 100 reduces, the pressure in cup body 12 is greater than the pressure of pumping chamber 100, the notch of waterproof valve 9
92 are opened, and the air in cup body 12 enters the second cylinder 26 and applies upward thrust to check valve 7, so that 7 He of check valve
Generate gap between second through-hole 24, gas, by the second through-hole 24, then passes through check valve fixing piece 6 and the by the gap
Gas passage between one through-hole 107 enters pumping chamber 100, until the pressure equilibrium in cup body 12 and pumping chamber 100.
When spring 34 is restored to nature, air pump inner cylinder 33, air pump outer cylinder 31 and the first sealing ring 32 are no longer to moving up
It is dynamic, pressing knob 5 is pushed down on, air pump inner cylinder 33, air pump outer cylinder 31 and the first sealing ring 32 is driven to move down, the first sealing
It is close to 31 bottom of air pump outer cylinder under the action of the inner wall of 32 third cylinder 102 in upper cover 1 of the circle frictional force upward to its
The second convex edge 315, gas in pumping chamber 100 passes through gap between the first convex edge 331 and third cylinder 102 and gas vent
It is connected to the external world, during air pump inner cylinder 33, air pump outer cylinder 31 and the first sealing ring 32 move down, the body of pumping chamber 100
Product reduces, and the pressure in pumping chamber 100 increases, and check valve 7 is logical with blocking second under the action of atmospheric pressure and self gravity
Hole 24 prevents air from entering cup body 12, and the gas in pumping chamber 100 passes through the gap between the first convex edge 331 and third cylinder 102
And row of exhausting-gas hole, to outside, until that can not push down on vacuum elements 3, spring 34 is in compressive state.Pressing is decontroled again
Knob 5, air pump inner cylinder 33, air pump outer cylinder 31 and the first sealing ring 32 move up under the elastic force effect of spring 34, in repetition
One step extracts the air in cup body 122 out, so recycles, the air in cup body is gradually emptied.
The present invention is equipped with vacuum elements 3,2 bottom of lower cover by the way that dismountable upper cover 1 and lower cover 2, the upper end of upper cover 1 is arranged
Equipped with waterproof valve 9, cup lid waterproof performance is good, check valve 7 is equipped between upper cover 1 and lower cover 2, cup lid is easily disassembled, easy to clean
Cup lid internal component, and structure is simple, compact layout, is easy to minimize.
The above, only better embodiment of the invention, but the present invention is not limited to above-described embodiments, as long as
The technical effect of the present invention is achieved by any identical or similar means for it, all should belong to protection scope of the present invention.
