Specific embodiment
Hereinafter, with reference to the accompanying drawings to describing embodiments of the invention in detail.However, it is possible to come real in many different forms
Apply the present invention, and the present invention should not be construed as limited to the specific embodiment that illustrates here.On the contrary, these enforcements are provided
Example is to explain the principle of the present invention and its practical application, so that others skilled in the art are it will be appreciated that the present invention
Various embodiments and be suitable for the various modifications of specific intended application.
In the present invention, need not any test equipment it is only necessary to a fritter adhesive tape can complete the IPX7 of water proof equipment
Can detect, whole test process is convenient and swift and testing result is accurate.
Refer to Fig. 1, Fig. 1 detects the method flow diagram of the method for IPX7 performance of water proof equipment, the present invention for the present invention
The method of the IPX7 performance of detection water proof equipment comprises the following steps：
Step one, the barometrical perforate on water proof equipment is instructed to.
Barometrical perforate is blocked completely by step 2 by adhesive tape；If also have on water proof equipment existed elsewhere
Perforate is it is also desirable to be blocked with adhesive tape.
Step 3, water proof equipment is started shooting, and LCDs are lit.
Step 4, enters air pressure count value display picture, and records barometrical initial value.
Step 5, detection time observes the change of air pressure count value after reaching, and records barometrical atmospheric pressure value, judges gas
Whether the difference between pressure value and initial value is more than detected value, if the difference between atmospheric pressure value and initial value is more than detected value,
Then testing result is judged to pass through, and otherwise, then testing result is judged to not pass through.
In the present invention, detection time is set as 1 minute, and detected value is set as 100pa, in other embodiments, inspection
Survey time and detected value can be other different values according to the different set of equipment to be tested.
Refer to Fig. 2, Fig. 2 detects the Cleaning Principle schematic diagram of the method for IPX7 performance of water proof equipment for the present invention.First
First it is assumed that the water proof equipment to be measured normal equipment that is sealing property, water proof equipment to be measured is regarded as an airtight sky
Between, its internal electronic device can generate heat when equipment works, thus leading to the air pressure of water proof equipment intracavity to rise.But, gas
Stream by barometrical perforate, and can carry out air pressure exchange through waterproof ventilated membrane, so intracavity air pressure is with extraneous air pressure also
It is to maintain consistent.Assume that in Fig. 2, water proof equipment to be measured is in off-mode, then intracavity pressure S is equal with pressure S ' outside chamber, this
When, record the initial value S=100915pa that barometer shows.
After blocking pressure hole with adhesive tape, the air outside intracavity can not be flowed mutually, and the air pressure of intracavity can be with temperature
Degree rising and constantly rise, now, the atmospheric pressure value that barometer shows rises to S=102928pa.
On the contrary, if water proof equipment to be measured has leakage, one minute afterwards atmospheric pressure value S will change less.Through actual verification,
In the present embodiment, the difference that standard detection passed through is set between atmospheric pressure value and initial value is more than 100pa, 100pa institute
Refer to atmospheric pressure value before detection after difference (difference=plug-hole S value after 1 minute-initial S value before and after S value).
Please refer to Fig. 3 to Fig. 6, Fig. 3 to Fig. 6 detects the detection of the method for IPX7 performance of water proof equipment for the present invention
Equipment schematic diagram.Can see, the present invention does not need any equipment it is only necessary to a fritter adhesive tape is as adjuvant.Whole process is not
Can accurately judge more than two minutes.First find the barometrical perforate on equipment, then sealed completely with a fritter adhesive tape
Block up barometrical perforate, if also having on equipment is being also required to same method closure of perforate elsewhere.Refer to figure
5, assume initially that tested product is sealing property OK.We can regard product as an airtight space, internal
Electronic device operationally heating can lead to the air pressure of intracavity to rise.But air-flow can carry out air pressure exchange by pressure hole,
So intracavity air pressure and extraneous air pressure or consistent.As figure to-be-detected machine is in off-mode, intracavity pressure S=chamber external pressure
Strong S ', at this moment we need to record the numerical value S=100915pa that barometer shows.Please continue to refer to Fig. 6, when being blocked with adhesive tape
After pressure hole, inside and outside air can not be flowed mutually, and the air pressure of intracavity constantly can rise with the upper high of temperature, this with
The principle of pressure cooker is similar.After 1 minute, we rise to S=102928pa seeing barometrical value.
Refer to Fig. 7, Fig. 7 detects the experimental data contrast chart of the method for IPX7 performance of water proof equipment for the present invention.
In order to more accurately judge, we have done the standard that 60 groups of data to define passs as the data tested.From test
The measuring accuracy that the data of checking can be seen that this invention is very consistent with traditional test equipment, then have passed through reality
What after IPX7 immersion test, we were very prudent is set to more than 100pa by the standard of pass, and 100pa referred to S value is before testing
The difference (difference=plug-hole S value after 1 minute-initial S value before and after S value) of shell.
The present invention detects the method for the IPX7 performance of water proof equipment compared with prior art, has advantages below：1st, this
Do not need any test equipment during bright detection, greatly facilitate the detection of end and customer side after sale；2nd, almost there is no cost, compare
Existing method of testing has greatly saved resource；3rd, the accuracy of test is very nearly the same with existing test result.
The present invention measures the air-tightness of whole machine using the electronic barometer that water proof equipment itself carries, and not only solves waterproof
The problem of equipment test and shorten the time of test moreover it is possible to test the waterproof wearing product of oneself or anti-anywhere or anytime
The IPX7 performance of sailor's machine.
Although illustrate and describing the present invention with reference to specific embodiment, it should be appreciated by those skilled in the art that：
In the case of without departing from the spirit and scope of the present invention being limited by claim and its equivalent, can here carry out form and
Various change in details.
