Specific embodiment
To keep the purpose of the present invention, feature, advantage more obvious and understandable, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is only
It is only a part of the embodiment of the present invention, and not all embodiments.Based on the embodiments of the present invention, those skilled in the art are not having
Every other embodiment obtained under the premise of creative work is made, shall fall within the protection scope of the present invention.
Fig. 1 is a kind of structural schematic diagram for tightness detector that one embodiment of the invention provides；
Fig. 2 is a kind of 100 cross-sectional view of sealing room for tightness detector that one embodiment of the invention provides.
As shown in Figs. 1-2, the embodiment of the present invention provides a kind of airtightness detecting element 300, comprising: sealing room 100, sealing
For placing object to be measured in room 100；Transformation element 200 is connected with sealing room 100, for adjusting the gas in sealing room 100
Press parameter；Detecting element 300 is connected, for detecting the deformation parameter of object to be measured with sealing room 100.
In the present embodiment, object 900 to be measured is placed in sealing room 100, due to the object to be measured 900 that is fully sealed
Air pressure inside parameter constant, the variable quantity of external pressure parameter are directly proportional to the surface deformation amount of object 900 to be measured.Therefore, if
900 airtightness of object to be measured is good, then can be obtained by one according to the pneumatic parameter variable quantity in sealing room 100 and meet the requirements
Object to be measured 900 deformation quantity, and object to be measured 900 when deformation parameter be unable to satisfy require when, it may be considered that be measured
There is certain leakage in object 900.When being detected, the air pressure that can be changed in sealing room 100 by transformation element 200 is joined
Number to change the internal and external pressure difference of object 900 to be measured, and then makes object 900 to be measured generate deformation, at this point, passing through detecting element
The deformation parameter of 300 objects to be measured 900 being able to detect that, later, as long as judging whether the deformation parameter of object 900 to be measured is full
Foot requires, that is, can determine whether determinand part 900 with the presence or absence of leakage.It whether there is leakage by detecting object 900 to be measured as a result,
It can find to detect airtightness problem present in object 900 to be measured in time, improve the reliability that object 900 to be measured uses.
As shown in Fig. 2, detecting element 300 is amesdial in device provided in this embodiment.Shape detected by amesdial
Variable element is the deformation quantity that object 900 to be measured is generated because internal and external pressure difference changes, therefore using amesdial as detecting element
300, can the more intuitive deformation quantitative response determinand part 900 according to object 900 to be measured airtightness, with improve deformation ginseng
The sensitivity of number detection.The pneumatic parameter in sealing room 100 can be changed by way of to sealing 100 pressure or decompression of room.
When changing the air pressure in sealing room 100 by the way of pressurizeing to sealing room 100, object 900 to be measured is recessed inwardly, and thousand
Divide table that will generate reverse deflection；When using to sealing room 100 using the pneumatic parameter changed by the way of negative pressure in sealing room 100
When, 900 outwardly convex of object to be measured, amesdial will generate positive deflection.Use amesdial as detecting element 300, can make
Tightness detector detects the deformation parameter for carrying out pressure alteration in different ways and changing, while increasing close
The popularity of closing property detection device measurement object.Wherein, detecting element 300 can also be the power being in contact with object 900 to be measured
Sensor, when transformation element 200 changes the pneumatic parameter in sealing room 100, object 900 to be measured can generate deformation, therefore can be right
Force snesor force, and force snesor can sense when the parameter of suffered power, deformation parameter can be according to force snesor institute
The parameter for the power being subject to is calculated.
In the present embodiment, amesdial includes test side and display end, and test side is located in sealing room 100, for it is to be measured
Object 900 is in contact and detects the deformation parameter of object 900 to be measured；Display end is located at outside sealing room 100, for showing that deformation is joined
Number.Need to read deformation parameter shown by detecting element 300 during detecting to object 900 to be measured, some are close
Closing property detection device uses the plate of glass material to make sealing room 100 to read the view number of detecting element 300, but glass material
Plate is burst when by internal and external pressure difference since hardness is not enough easy to produce, therefore, in order to ensure that the stability of detection work, leads to
Often confined chamber is made using the plate of steel material.Again because detecting element 300 is needed when being detected to object 900 to be measured and to
Survey object 900 directly contacted, therefore, when in order to guarantee to detect object 900 to be measured, detecting element 300 with it is to be measured
Object 900 can observe deformation parameter shown by detecting element 300 while being persistently kept in contact state, combine detection
Display end using the inside that the test side of amesdial is placed in sealing room 100 and can be placed in sealing room by the stability of work
100 outside, to accurately be carried out to the deformation parameter of object 900 to be measured on the basis of guaranteeing to seal 100 gas-tight property of room
Measurement and reading.
As shown in Figs. 1-2, in the present embodiment, transformation element 200 is vacuum generating device, and vacuum generating device is for extracting

When with the material for being easy to produce deformation, it is usually provided on the inside of such 900 closure of object to be measured and is used to support closing
Shell and/or support portion for guaranteeing 900 Inner structural shape of object to be measured, when to sealing room 100 to object 900 to be measured into
When row pressurization, the support portion inside object 900 to be measured may be caused to ruin when the closure of object 900 to be measured is recessed inwardly
Damage, and then biggish destruction is caused to object 900 to be measured.It is therefore possible to use vacuum generating device carries out object 900 to be measured
Negative pressure, and then object 900 to be measured is made to generate expansion with the detection of being sealed property.In addition, when object 900 to be measured is lithium battery
When Deng the object being sealed under vacuum conditions, need to seal using vacuum generating device the air pressure drop in room 100 down to
Atmospheric pressure value when less than vacuum, with guarantee object 900 to be measured can outwardly convex, so that it is guaranteed that airtightness detection it is accurate
Property.
