Embodiment one:
The present embodiment provides a kind of air pump, which be can be applied in all kinds of inflation/deflation structures, such as in electronic sphygmomanometer.
Please refer to Fig. 1-4, in a kind of embodiment, which includes the first component 110, second component 120 and driving dress
Set 130.Wherein, which is only a kind of signal, does not show specific structure.
In the present embodiment, 130 outputting reciprocating linear movement of driving device.Driving device 130 and second component 120 connect
It connects, for driving 120 relative thereto 110 of second component close and separate.In addition to this, in other embodiments, drive
Device 130 can be used for the driving first component 110 or driving device 130 while drive the first component 110 and second component
120, the first component 110 and second component 120 are relatively distant from and relatively close movement to realize.When driving device 130 is same
When the driving first component 110 and when second component 120, can be driven with the same power source, such as pass through different biographies
Motivation structure drives the first component 110 and second component 120 respectively；Different dynamic source can also be used, the first component is respectively driven
110 and second component 120.
As shown in Figures 2 and 3, the two can be made to be formed when being located remotely from each other when the first component 110 and second component 120 have
The connection structure of seal cavity A.The cavity wall of seal cavity A be provided with the first air flue 111 for being connected to exterior space and
The second air flue 112 for being connected to gas storage chamber 140.
First air flue 111 penetrates through the first component 110, can be and is positioned only on the first component 110, is also possible to first
Part 110 is collectively constituted with other structures.First air flue 111 is the first opening towards the open at one end of second component 120, this first
The open at one end of 111 facing external space (such as atmospheric pressure) of air flue is the second opening.
In order to make second component 120 when being rapidly directed away from the first component 110, one is capable of forming close to vacuum state
The area of seal cavity A, one side b of the second component 120 towards the first opening are greater than the opening area of the first opening, make first
It is open and is fallen on the one side b towards the first opening in the orthographic projection on second component 120.That is, as illustrated in fig. 1 and 2, this second
The area of one side b horizontal direction of the part 120 towards the first opening is greater than the opening area of the first opening, and first opening is just
Projection is entirely fallen in the range of this one side of second component 120 b.
120 relative thereto 110 of second component far from when, second component 120 can be temporary by the gas of the first opening
It takes away, to form an of short duration vacuum space.Since the air pressure of seal cavity A is subatmospheric, it is assumed that close close to vacuum
Positive differential pressure is formed between exterior space (such as atmospheric pressure) and seal cavity A except envelope cavity A, external gas is under this pressure difference
Enter seal cavity A by the first air flue 111.Although gas storage chamber 140 may also when seal cavity A is preliminarily formed
It can be entered in seal cavity A by the second air flue 112, but the gas in gas storage chamber 140 will not be full of seal chamber moment
Body A, therefore seal cavity A always sucks gas from exterior space.
As shown in figure 4, when driving device 130 drive second component 120 to the first component 110 close to when, at this moment seal chamber
Gas in body A is compressed by second component 120, respectively from the first air flue 111 and the second air flue 112 flow out to exterior space and
In gas storage chamber 140.But pressure difference when air inlet is much smaller than due to the pressure difference of seal cavity A and free surrounding space at this time, this
When from the flow that the first air flue 111 is vented much smaller than from the first 111 air inlet of air flue when flow, more gases are from the second air flue
112 enter gas storage chamber 140.It is repeated, is can be completed to charge operation in gas storage chamber 140 with this.
By taking exterior space is atmospheric pressure as an example, when seal cavity A is initially formed, between exterior space and seal cavity A
Pressure difference reached 760mmHg i.e. 101.3kPa, the gas of exterior space is entered under this pressure difference in seal cavity A at this time.
When second component 120 and the first component 110 close to when, at this time generally required for the sphygmomanometer for maximum pressure (pressure),
Assuming that air pressure has reached maximum pressure generally required for sphygmomanometer (pressure) in seal cavity A and gas storage chamber 140 at this time,
I.e. 300mmHg, that is, 40kPa higher than atmospheric pressure, seal cavity A and the interior pressure difference with external pressure of gas storage chamber 140 are at this time
300mmHg, that is, 40kPa.Under same time and environment, since flow velocity of the gas in the first air flue 111 and flow are and pressure difference
Directly proportional, it follows that being greater than the flow of exhaust from the flow of 111 air inlet of the first air flue.The first component 110 and second component
120 are formerly located remotely from each other, then it is close to each other during, finally from the first air flue 111 flow into seal cavity A gas be more than from
The gas of first air flue 111 discharge, it is repeated multiple times, it can be completed and carry out pneumatic compression to gas storage chamber 140.This air pump is complete
It can be realized the inflation requirement of electronic sphygmomanometer entirely.
This air pump suction and discharge rely on the high speed and small relative motions of the first component 110 and second component 120, are not necessarily to
Excessively complicated structure.By taking Fig. 2 as an example, it is assumed that 150 gabarit size of cavity body structure is φ 5*3, the first component 110 is cavity body structure
150 a part, and second component 120 is φ 4, the first air flue 111 are the hole of φ 0.5, and driving device 130 is one to provide the
Air pump can then be accomplished that φ 5*3 is big to the device of 110 amount of relative motion 0.1mm of the first component (even more small) by two components 120
It is small.This air pump is smaller than the prior art, is more conducive to be applied on the electronic sphygmomanometer of wearable type.
Further, in one embodiment, the first component 110 and second component 120 be located remotely from each other movement and mutually
Close to movement between switching be seal cavity A air pressure be less than or equal to 140 air pressure of gas storage chamber when progress, i.e., second
Part 120 is also not up to the air pressure or just of gas storage chamber 140 after far from the first component 110, in seal cavity A air pressure
It is just reversely moved to the first component 110 when reaching the air pressure of gas storage chamber 140.This can reduce the gas in seal cavity A
The amount flowed out from the first air flue 111, it is as much as possible that gas is discharged in gas storage chamber 140.
Further, in some embodiments, the first component 110 and second component 120 are located remotely from each other movement and mutually lean on
Switching between nearly movement, which can also be, is less than or reaches the moment progress of exterior space air pressure in seal cavity A air pressure, i.e., and the
Two components 120 are also not up to the air pressure or just of exterior space after far from the first component 110, in seal cavity A air pressure
It is just reversely moved to the first component 110 when reaching the air pressure of exterior space.In this way, before 120 counter motion of second component, sealing
Cavity A will not be further reduced gas in seal cavity A from because of the pressure difference with exterior space and to external aperture vents
The amount of one air flue 111 outflow, it is as much as possible that gas is discharged in gas storage chamber 140.
Referring to FIG. 4, second component 120 can be made to keep position shown in Fig. 4, i.e. second component when needing to be vented
120 keep discrete state for a period of time with the first component 110, since the air pressure in seal cavity A and gas storage chamber 140 is final
It is above atmospheric pressure, therefore its interior gas can flow out to outside atmospheric pressure from the first air flue 111 automatically.
In some embodiments, have between the first component 110 and second component 120 for making 110 He of the first component
Second component 120 keeps isolated elastic component.In this way, the elastic component can pass through itself when driving device 130 stops working
Elasticity makes the first component 110 and second component 120 keep discrete state, to be vented, to save energy, without passing through driving
Device 130 separates the first component 110 and second component 120.
In some embodiments, elastic component can form integral structure with the first component 110 or second component 120.
Further, Fig. 1 and 2 is please referred to, in a kind of embodiment, the first component 110 and second component 120 are mutually to paste
