Increase or reduce the occurrence quantity of gas so that the equalization point that mobile terminal is in protection and does not protect.It can accurately examine in this way
Measure whether mobile terminal needs protection and its protection class.
Fig. 7 is a kind of application signal of gas barrier protective device for mobile terminal of fifth embodiment of the invention
Figure, as shown in fig. 7, the embodiment is different from being in place of fourth embodiment, which is protected against the effects of immersion mechanism；The protected against the effects of immersion
Mechanism in order to control caused by the gas flow velocity to generate the internal pressure in the mobile terminal, make the internal pressure and the shifting
The external pressure balance of dynamic terminal.The control unit 23 controls flow caused by the gas and is more than the gas from the mobile terminal
The discharge capacity of discharge.
The embodiment is mainly used for the decision-making mechanism run when danger of flooding occurs for mobile terminal.
The main operational principle of the embodiment is to be realized using gas pressure intensity, when being full of air inside mobile terminal, and
It is consistent with environmental stress, then when gas generator 2 generates the air of monoploid product again, according to Ideal Gas Pressure Expressions PV/T
=const, then pressure increasing is twice.Since gas can continue to leak, pressure can be more obtained than Ideal Gas Pressure Expressions
Pressure is low, therefore anti-water depth should be less than h=P/ (ρ g)=10 meters.But the occurrence quantity of the gas persistently generated is more than excretion
When, internal pressure can continue to increase until pressure equilibrium, and inside and outside pressure plays waterproof action when consistent.In above-mentioned two formula, P is big
Air pressure is strong, and V is gas volume, and T is environment temperature, and const is constant, and h is the depth of water, and ρ is water density, g=10.In this decision
Under mechanism, the big gas of compression ratio is preferred in generated gas, can guarantee that the air bag 21 of same memory space stores more
Gas.
Same fourth embodiment, the embodiment can also actively inspire the protected against the effects of immersion machine by the way that a protected against the effects of immersion button is arranged
System, the protected against the effects of immersion button can by being implanted into corresponding software in the terminal to generate corresponding control in control interface,
To realize control, a miniature keyboard can also be added so that a wherein physical button is arranged and inspire the protected against the effects of immersion mechanism.When with
When family finds that mobile terminal ambient humidity is larger, mobile terminal may detect because of sensor and cause to inspire not in time
Mechanism lags, then user can click the protected against the effects of immersion button to realize the protected against the effects of immersion mechanism of the mobile terminal.
The advantageous effect of the embodiment is, when danger of flooding occurs for mobile terminal, volume production will occur with maximum gas
Angry body quickly improves the pressure of terminal inner gas, to reduce the possibility that outside liquid enters terminal inner as possible.
Fig. 8 is a kind of application signal of gas barrier protective device for mobile terminal of sixth embodiment of the invention
Figure, as shown in figure 8, the embodiment is different from being in place of fourth embodiment, which is anti-dust mechanism；The anti-dust
Mechanism in order to control caused by the gas flow velocity, and the flow direction for controlling the gas is directed at following position：It listens on the inside of microphone, button
On the inside of inside, Mike hole.
The embodiment mainly actively inspires the anti-dust mechanism by the way that an anti-dust button is arranged, such as the 4th implementation
Example, the anti-dust button can by being implanted into corresponding software in the terminal to generate corresponding control in control interface,
To realize control, a miniature keyboard can also be added so that a wherein physical button is arranged and inspire the anti-dust mechanism.Pass through
Gas flow is directed at the arbitrary opening of mobile terminal, and adjusting gas flow rate can prevent mobile terminal external dust from entering movement eventually
End is internal.
The sensor module 1 of the embodiment can also include a dust sensor, and the dust sensor for detecting in real time
The Dust Capacity parameter is simultaneously back to the gas generator by the Dust Capacity parameter of the mobile terminal local environment in real time.The control list
After member 23 receives the Dust Capacity parameter, a protection class is generated in real time according to the Dust Capacity parameter, and according to the protection etc.
Grade runs preset anti-dust mechanism；The anti-dust mechanism in order to control caused by the gas flow velocity, and control the gas
Flow direction is directed at following position：It listens on the inside of microphone, on the inside of button, on the inside of Mike hole.Preferably, the protection class and anti-dust mechanism
Correspondence it is as shown in the table：
1 Dust Capacity of table and protection class relation table

| 1 | 0~35 μ g/m3 |
| 2 | 35~75 μ g/m3 |
| 3 | 75~115 μ g/m3 |
| 4 | 115~150 μ g/m3 |
| 5 | 150~250 μ g/m3 |
| 6 | More than 250 μ g/m3 |
As shown above, the more high corresponding Dust Capacity of protection class is higher, therefore control unit 21 not only needs control to be produced
The flow direction of the raw gas will also control the flow velocity of the generated gas, and the flow velocity of gas can also be by gas flow meter
Sign.Protection class is higher, and the flow for controlling the generated gas is bigger, it is preferred that the flow of the protection class and gas
Correspondence is as shown in the table：
