Specific embodiment
The invention patent has 3 kinds of more representational specific embodiments, and embodiment of the present invention is not limited to 3 kinds,
Many different specific embodiments can be generated by its similar structure and principle.It can by following 3 kinds typical embodiments
With find out they nuclear structure and principle be it is completely the same, meet every technical characteristic in claim, variation only
It is some format surfaces.The invention patent can also apply to anti-overflow lock, will be seen that its relevant technologies by anti-overflow lock introduction.
Embodiment 1:
1 pair of embodiment 1 carries out general explanation with reference to the accompanying drawing.
Pen etc. is seated on coupling sleeve 1 (coupling sleeve is made by the elastic softwood such as rubber or TPU), on air pump piston
During drawing, negative pressure of vacuum will form in air pump operating room 11, pumping check valve mouth 10 of holding one's breath can be opened, the air in pen gallbladder
It can be pumped into air pump operating room by pumping check valve bleeding point 12；Exhaust check valve holds one's breath mouth 13 can reason air pump operating room
Negative pressure close；Current limiting tube or metering hole 5 enter connection because the negative pressure of air pump operating room can suck the ink of lowest part and struggle against, take out
Inside gas check valve, air pump operating room, exhaust check valve, coupling sleeve etc., these inks can significantly improve their air-tightness.
During air pump piston pushes, air pump operating room can generate positive pressure because of the partial air of entrance, be evacuated check valve
Mouth 10 of holding one's breath can close；The mouth 13 of holding one's breath of exhaust check valve can be opened；Air and a small amount of ink can be arranged by exhaust check valve
Port 14 enters in bottle body 7.
At this moment, it has been pumped into vacuum in pen gallbladder, the pumping check valve being attached thereto is in close state, and simultaneously therewith
Connected current limiting tube or metering hole be it is always on, it can sucking ink function enters pen gallbladder due to the negative pressure of vacuum in pen gallbladder
In.
It is moved back and forth by multiple (pen of low capacity have secondary can) of air pump piston, the air meeting in pen gallbladder
It is pumped more thoroughly, upper water will more sufficiently.
In air pump pumping process, negative pressure distribution is had always in current limiting tube or metering hole, current limiting tube or metering hole are
When in bottle body use state lowest part (if had not in lowest part ink inhale less than), just there is ink to exist always
It is distributed in whole system, and the flow resistance of ink is much larger than the flow resistance of air, ensure that the gas-tight property of whole system.Limit
The internal diameter of flow tube or metering hole requires the internal diameter being made than all components and channel in vacuum in water bottle small (will actually answer small
3 times or more even tens times or more, the difference more big upper water of ratio is more abundant, but time-consuming also more long), flow resistance here is most
Big, therefore negative pressure of vacuum not will cause decompression influence herein, would not influence the air extracted in barrel.
The present embodiment does not set up aerating system, and the gas that air pump is pumped into cannot be discharged to outside bottle body, can only remain in bottle
Compressed air is formed in vivo.When stopping pumping starting upper water, the ink in bottle body can be entered the pen of vacuum state by throttle orifice
In gallbladder, the output of ink can vacate an additional space in bottle, and compressed air just now can just fill up this space.If
The capacity of barrel is big, and the air and the compressed air that is formed in bottle that air pump is pumped into also increase, and the ink that exports and in bottle
The space vacateed also accordingly is increased, this final compressed air increased just offsets with the space increased in bottle balance.Conversely,
If barrel amount appearance is small, the air of extraction and the compressed air of formation are just few, and the ink of output and the space vacateed in bottle are just
Few, finally few compressed air and few space reach air water balance.Circulating vacuum watering machine is in fact namely in as can be seen that
Ink in air and bottle body in barrel is replaced, space may eventually reach high balance.But compressed air
It generates and will increase the load of air pump work done, use harder, and performances such as sealing that will affect system.Therefore by this
The pressure release of compressed air, can be solved there are three discharge technical solution altogether: first is that water bottle fills ink on interior circulating vacuum
Shi Buke is full up will to reserve certain gas storage space, this can obviously reduce pressure；Second is that on interior circulating vacuum water bottle bottle body or lid
The slightly increased deformation of meeting, pressure are restored after disappearing after son is pressurized by the flexible material production (such as PET) with certain extensibility
Original shape；Third is that the discharge capsule 20 for specially adding a soft elasticity material production on water bottle on interior circulating vacuum (is located at bottle body
Or on bottle cap), it can be expanded after being pressurized and expand volume to realize discharge.Three kinds of technical solution alternatives use, can also be simultaneously
Using.The discharge scheme that the present embodiment uses is the first or second.
Here pumping check valve 3 and exhaust check valve 4 is by the materials processing and fabricating such as glass or stainless steel.
Embodiment 2:
2,3,4,5,6 pairs of embodiments 2 carry out general explanation with reference to the accompanying drawing.

In air pump operating room；Exhaust check valve hold one's breath mouth 13 can reason air pump operating room negative pressure close；Metering hole or metering hole 5 can be because
The negative pressure of air pump operating room can suck the ink of lowest part unidirectional into connection bucket, pumping check valve, air pump operating room, exhaust
Inside valve, coupling sleeve etc., these inks can significantly improve their air-tightness.
During air pump film uplink, air pump operating room can generate positive pressure because of the partial air of entrance, be evacuated check valve
Mouth of holding one's breath can close；The mouth 13 of holding one's breath of exhaust check valve can be opened；Air and a small amount of ink can pass through exhaust check valve exhaust outlet
14 enter in bottle body 7.
At this moment, it has been pumped into vacuum in pen gallbladder, the pumping check valve being attached thereto is in close state, and simultaneously therewith
Connected metering hole or current limiting tube be it is always on, it can sucking ink function enters barrel due to the negative pressure of vacuum in pen gallbladder
In.
It is repeatedly moved back and forth by air pump film, the air in barrel can be pumped more thoroughly, and upper water will more sufficiently.
The discharge scheme of the present embodiment is specially to add the discharge capsule 20 of a soft elasticity material production to realize.Discharge
Capsule is highly elastic material (such as rubber) production.Prototype can be restored at once with easy expansion, pressure disappearance by encountering pressure.
Here pumping check valve 3 and exhaust check valve 4 is by the elastic softwood production such as rubber.
The air pump of this embodiment is driven by motor 15 and battery 16 or external power supply.After penholder is got well, dub
Trigger switch 18, time delay module 17 will according to set time (this time be in module it is adjustable, be suitble to difference
The pen of capacity) complete air pump movement and voluntarily phase down.
There are two types of control circuits, can choose any one kind of them: first is that time delay module circuit (Fig. 3)；Second is that switching circuit (Fig. 5).It opens
Powered-down road eliminates time delay module, and cost is lower, but the annoying work of labor is needed to go to close circuit switch 19 when in use.
Embodiment 3:
7,8 pairs of embodiments 3 carry out general explanation with reference to the accompanying drawing.
Pen etc. is seated on coupling sleeve 1, during drawing outside air pump piston, will form vacuum in air pump operating room 11
Negative pressure, pumping check valve mouth 10 of holding one's breath can be opened, and the air in pen gallbladder can be pumped into gas by pumping check valve bleeding point 12
In pump working chamber；Exhaust check valve hold one's breath mouth 13 can reason air pump operating room negative pressure close；Current limiting tube or metering hole 5 are because of air pump
The negative pressure of operating room can suck the ink of the ink of lowest part into connection bucket, pumping check valve, air pump operating room, exhaust list
Inside to valve, coupling sleeve etc., these inks can significantly improve their air-tightness.(piston rod for air pump of the present embodiment is place
In the lower section recess of bottle body, so can bottle body be laid flat or is inverted in order to facilitate the operation when in use, therefore current limiting tube is usually located
It above, is when in use to be below).
In air pump piston push-on process, air pump operating room can generate positive pressure because of the partial air of entrance, be evacuated check valve
Mouth 10 of holding one's breath can close；The mouth 13 of holding one's breath of exhaust check valve can be opened；Air and a small amount of ink can be arranged by exhaust check valve
Port 14 enters in bottle body 7.
At this moment, it has been pumped into vacuum in pen gallbladder, the pumping check valve being attached thereto is in close state, and simultaneously therewith
Connected current limiting tube or metering hole be it is always on, it can sucking ink function enters pen gallbladder due to the negative pressure of vacuum in pen gallbladder
In.
By the multiple reciprocating motion of air pump piston, the air in pen gallbladder can be pumped more thoroughly, and upper water will more fill
Point.
The discharge scheme of the present embodiment is specially to add the discharge capsule 20 of a soft elasticity material production to realize.Discharge
Capsule is highly elastic material (such as rubber) production.Encountering pressure can easily shrink, and pressure disappearance restores prototype at once.
Here pumping check valve 3 and exhaust check valve 4 is by the materials processing and fabricating such as glass or stainless steel.
Anti-overflow lock introduction:
9,10,11,12,13,14,15,16 pairs of anti-overflow locks carry out general explanation with reference to the accompanying drawing.
The present invention eliminates aerating system by the way of interior circulation, then consequently also will appear corresponding problem.There is ventilation
Water bottle does not insert pen regardless of inserting on coupling sleeve in the vacuum of system, and air pump can arbitrarily be run.The present invention is then not all right, if connection
Without slotting pen in female connector, after air pump operation, the air being pumped into bottle body is not limited, and may be pumped into very big amount
(and pen has been inserted on coupling sleeve then by the limitation by barrel capacity, as soon as then how to take out and can also be limited in an amount, the amount of being extracted into
Do not have air to take out).Air pump be pumped into unrestricted air form a large amount of compressed airs in bottle body and can not be from blow vent or logical
Air valve discharge (water bottle is provided with blow vent or breather valve on non-interior circulating vacuum) is opened again without pen in one kind in coupling sleeve
State is put, the ink in a large amount of compressed airs meeting extrusion bottle in bottle body is endlessly gushed out along metering hole or current limiting tube,
A large amount of inks can be overflowed in coupling sleeve.
In order to avoid this bad situation, there are two types of solving, technical solution is optional: mentioning first is that making on product or packaging
It wakes up, warning forbids booster air pump on coupling sleeve without inserting pen etc.；Second is that specially installing an anti-overflow lock, anti-overflow lock additional
It is made of coupling sleeve matte 21, return spring 22, lock axis 23, lock convex 24 etc., wherein being installed in manual type on circulating vacuum
Anti-overflow lock lock on water bottle is convex for preventing air pump from working, the anti-overflow lock lock being installed in electronic mode on circulating vacuum on water bottle
It is convex to be used to be connected to air pump circuit.
In the state ofs in coupling sleeve without slotting pen or barrel etc., coupling sleeve matte 21 allows its Gai Lian by return spring 22
Fixation position in female connector, this time gating convex 24, which blocks piston rod for air pump top, enables air pump that cannot run or leave microswitch 25
Allow it not in closed state；Afters being inserted into pen etc. in coupling sleeve, coupling sleeve matte can be squeezed by pen and be removed, the lock being connected with lock axis
It is convex also to be moved with the rotation of lock axis, it then decontrols piston rod for air pump limitation or item lives microswitch by circuit communication, when
After one extraction of pen, return spring can send coupling sleeve matte back to original position at once, on the convex position for returning to beginning of lock.Therefore only exist
It is inserted in the case where pen etc. that lock is convex just finally to allow air pump that can run in coupling sleeve, is prevented from operation error in this way and occurs
The bad phenomenon of ink overflow.
Installing anti-overflow lock additional can be there are many structure and mode be planted, and specifically this will be according to water bottle on specific interior circulating vacuum with which kind of
Money shape determine, just do not repeat here.It may be said that corresponding anti-overflow lock can be all added in every kind of embodiment, only some
It installs parts additional mostly and span causes greatly cost too high (such as embodiment 3), not as good as by the way of warning and informing.
After embodiment 2 installs anti-overflow lock additional, the coupling sleeve matte of anti-overflow lock can hold a concurrent post connection upper shield again, instead of independent
Connection upper shield 9.
