As shown in Figure 1, Figure 2, Figure 3 shows, the arrow in figure indicates the flow direction of air, and the utility model provides one kind and is used for
The vacuum cover of container, including cap body 1, cap body 1 are equipped with normally closed switch 2, normal open switch 3, vacuum evacuation device, wraping plate
Formula button 4 and feedback gas cabin 5 for detection container inner cavity vacuum degree, normally closed switch 2, normal open switch 3 and vacuum evacuation device
It is connected into a closed circuit；Press-fit is pressed in the first end 4a of moving seesaw-type button and the formation of normally closed switch 2, and the of moving seesaw-type button
The air pressure balance mouth 6a of two end 4b and a tee pipe fitting 6, which is formed, presses press-fit, and vacuum evacuation device is true with above-mentioned tee pipe fitting 6
Empty pump port 6b connection, feedback gas cabin 5 and normal open switch 3, which are formed, presses press-fit；
When cap body 1 is connected with the sealing of the open end of container 7, the reservoir mouth 6c and appearance of above-mentioned tee pipe fitting 6
The inner cavity 7a of device is connected to.Said vesse 7 can be blender, be also possible to other container for storing.
In the present invention, the first end 4a of moving seesaw-type button is for controlling being switched on or switched off for normally closed switch 2, wraping plate
The second end 4b of formula button is used to control the dredging or closing of the air pressure balance mouth 6a of tee pipe fitting 6；Feeding back gas cabin 5 can be with container
Inner cavity vacuum degree variation and collapse (when the inner cavity vacuum degree of container is got higher, feedback gas cabin 5 volume can gradually taper up；
When the inner cavity vacuum degree of container becomes smaller, the volume in feedback gas cabin 5 can gradually expand) so that connecing for normally closed switch 2 can be controlled
On-off is opened；When the vacuum cover by the utility model is to a container vacuum-pumping, normally closed switch 2 and normal open switch 3 are controlled jointly
The operation or stopping of vacuum evacuation device processed, and the inner cavity vacuum degree of container can be made to reach setting value, can not only it extend in this way
The holding time of food in container, it is also ensured that the fresh taste after food preservation.
The use principle of the utility model is as follows:
When pressing the second end 4b of moving seesaw-type button: the first end 4a of moving seesaw-type button is separated with normally closed switch 2, normally closed
Switch 2 is connected；Since the inner cavity 7a of container is not also vacuum, feedback gas cabin 5 is in swelling state, and the pressing of feedback gas cabin 5 is normal
On switch 3, normal open switch 3 is in an ON state；The air pressure in tee pipe fitting 6 is pressed due to the second end 4b of moving seesaw-type button
On balance port 6a, close the air pressure balance mouth 6a of tee pipe fitting 6；Normally closed switch 2 and normal open switch 3 are also turned on, and are vacuumized
Device brings into operation, and continues to be evacuated outward to the inner cavity 7a of container, and at the same time, the volume in feedback gas cabin 5 gradually tapers up；Work as appearance
When the inner cavity vacuum degree of device reaches setting value, feedback gas cabin 5 is separated with normal open switch 3, so that normal open switch 3 be made to disconnect, is taken out true
Empty device stops pumping.
When pressing the first end 4a of moving seesaw-type button: the first end 4a of moving seesaw-type button is pressed on normally closed switch 2, often
Make and break is closed 2 and is disconnected；The second end 4b of moving seesaw-type button is separated with the air pressure balance mouth 6a of tee pipe fitting 6, makes the gas of tee pipe fitting 6
Balance port 6a dredging is pressed, external air flows into tee pipe fitting 6 through the air pressure balance mouth 6a of tee pipe fitting 6, and through tee tube
The reservoir mouth 6c of part 6 flows into the inner cavity 7a of container, keeps the inner cavity air pressure of container identical as atmospheric pressure；It is fast to feed back gas cabin 5
Speed expansion, until pressing on normal open switch 3, connects normal open switch 3；At this point, normally closed switch 2 disconnects, normal open switch 3 is connect
Logical, vacuum evacuation device is still in halted state, and user can remove vacuum cover from container, pour out the food in container
(such as fruit juice).
Above-mentioned vacuum evacuation device includes vacuum pump 8, exhaust tube 9 and exhaust pipe 10, one end of exhaust tube 9 and tee pipe fitting
6 vacuum pumping opening 6b connection, and the other end of exhaust tube 9 is connected to the air inlet of vacuum pump 8, one end of exhaust pipe 10 and
The gas outlet of vacuum pump 8 is connected to.When vacuum pump 8 is run, container of the interior intracavitary air of container first through tee pipe fitting 6 connects
Port 6c enters tee pipe fitting 6, and then the vacuum pumping opening 6b through tee pipe fitting 6 flows into exhaust tube 9, finally followed by pumping
It pipe 9, vacuum pump 8, exhaust pipe 10 and is discharged into outside container.
In order to make above-mentioned feedback gas cabin 5 be able to detect that the inner cavity vacuum degree of container, inner cavity and the exhaust tube in gas cabin 5 are fed back
9 connections.At this point, gas cabin 5 passes sequentially through exhaust tube 9 to feedback, tee pipe fitting 6 is communicated with the inner cavity of container.
For the ease of pressing above-mentioned normally closed switch 2, the switch cover that can be moved up and down is additionally provided in above-mentioned cap body 1
11, switch cover 11 is located between the first end 4a and normally closed switch 2 of moving seesaw-type button.
In order to guarantee after pressing the second end 4b of moving seesaw-type button, the second end 4b of moving seesaw-type button is not tilted, on
It states and is additionally provided with cage knob pin in cap body 1, moving seesaw-type button 4 is equipped with pin hole；As the second end 4b for pressing moving seesaw-type button
When, cage knob pin heads into pin hole.When needing to press the first end 4a of moving seesaw-type button, cage knob pin is extracted out of pin hole
?.
In conclusion the utility model can make the inner cavity vacuum degree of container reach setting value, the preservation of food is extended
Time ensure that the fresh taste after food saves.So the utility model effectively overcomes various shortcoming in the prior art
And has high industrial utilization value.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the revealed essence of the utility model
All equivalent modifications or change completed under mind and technical idea, should be covered by the claim of the utility model.
