Abstract
The utility model relates to an automatic power off device of a wet cell phone. The automatic power off device comprises a protective circuit and a connecting line, wherein the connecting line is arranged in a gap of the cell phone and is connected on the protective circuit; the protective circuit is provided with a microwave electronic trigger; and the protective circuit is connected with a cell phone chip through the connecting line. With the adoption of the automatic power off device of the wet cell phone, an automatic power off protective method for circuits of the wet cell phone is safe.
Description
Technical field
The utility model relates to the mobile communication technology field, is specifically related to a kind of mobile phone water inlet auto-power-off device.
Background technology
The careless mobile phone of water inlet, internal circuit short circuit easily, thus cause chip for cell phone to be burnt out and can't use.After the mobile phone water inlet, even can automatic shutdown also can't avoid internal circuit to be burnt because of the water inlet short circuit.Patent: a kind of waterproof mobile phone battery 200920307108; This patent is equipped with humidity sensor on battery container; Output at battery is connected to a switch triode and a battery protection integrated circuit that is controlled by humidity sensor; After the mobile phone water inlet,, humidity sensor then can cut off the power supply automatically when detecting moisture.At present technology only with the phone housing sealing do better, but can't avoid mobile phone water inlet problem fully, the mobile phone waterproof technique only limits to provide the method for mobile phone waterproof bag and battery of mobile phone water-proofing treatment thereof, can't be from the inner root problem that solves the water inlet short circuit of mobile phone.
Summary of the invention
The utility model has overcome the deficiency of prior art; Proposed a kind of mobile phone water inlet auto-power-off device, said mobile phone water inlet auto-power-off device need not be provided with humidity sensor in mobile phone, only need a protective circuit; After the mobile phone water inlet; Protective circuit meeting short circuit, and then cut off subsequent conditioning circuit automatically, thus play the effect of protection subsequent conditioning circuit.Compared with prior art, this patent setting is simpler, and has avoided the sensor problem of sensitivity inadequately, thereby makes the circuit safety and reliability, and the mobile phone waterproof effect is better.
The technical scheme of the utility model is: a kind of mobile phone water inlet auto-power-off device; Comprise protective circuit and connection line; Place, slit at mobile phone arranges connection line; Said connection line is connected on the said protective circuit, on said protective circuit, is provided with the miniature electronic trigger, and said protective circuit is connected with chip for cell phone through connection line.
The miniature electronic trigger is an electric capacity, and the capacity of said electric capacity is between 100-300 μ F.
The miniature electronic trigger can be the miniature electronic switch.
Said connection line is connected with phone housing.
If the miniature electronic trigger is an electric capacity, said protective circuit is met the water short circuit, and electric capacity will puncture, thereby this circuit can cut off the power supply with the connection line of said chip for cell phone and with mobile phone automatically in automatic cut-out;
If the miniature electronic trigger is the miniature electronic switch, behind the chance water, power on circuitry, said miniature electronic switch opens circuit, thus this circuit can cut off the power supply with the connection line of said chip for cell phone and with mobile phone automatically in automatic cut-out;
Chip for cell phone can not burnt because of meeting the water short circuit like this, thereby has protected chip for cell phone.Behind the mobile phone shutdown, can mobile phone be dried the use of can starting shooting.
The utlity model has following beneficial effect:
1) the utility model need not rely on mobile phone peripheral hardware waterproof, and is more convenient.
2) method of the automatic power-off protection of the utility model mobile phone water inlet circuit is very safe.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Fig. 1 is mobile phone water inlet auto-power-off device structural representation.
1. mobile phone; 2. connection line; 3. protective circuit; 4. chip for cell phone.
Embodiment:
Referring to shown in Figure 1; The utility model is mounted in a kind of new-type circuit on the mobile phone; Comprise protective circuit 3 and connection line 2, arrange connection line 2 at the place, slit of mobile phone, said connection line 2 is connected on the said protective circuit 3; On said protective circuit 3, be provided with the miniature electronic trigger, said protective circuit logical 3 is crossed connection line 2 and is connected with chip for cell phone 3.The miniature electronic trigger can be electric capacity, and the capacity of said electric capacity is between 100-300 μ F.The miniature electronic trigger can be the miniature electronic switch.Said connection line 2 is connected with phone housing.If the miniature electronic trigger is an electric capacity, said protective circuit 3 is met the water short circuit, and electric capacity will puncture, thereby this circuit can cut off the power supply with the connection line 2 of said chip for cell phone and with mobile phone automatically in automatic cut-out; If the miniature electronic trigger is the miniature electronic switch, behind the chance water, power on circuitry, said miniature electronic switch opens circuit, thus this circuit can cut off the power supply with the connection line 2 of said chip for cell phone and with mobile phone automatically in automatic cut-out.Specifically be embodied as: connection line 2 on the place, slit of said mobile phone 1 cloth; Said connection line 2 is connected on the protective circuit 3 of a miniature electronic trigger; Said protective circuit 3 links to each other with chip for cell phone 4 through connection line 2. if said protective circuit 3 is met the water short circuit; Said miniature electronic trigger opens circuit, thereby this circuit can cut off the power supply with the connection line 2 of said chip for cell phone 4 and with mobile phone automatically in automatic cut-out.Said like this chip for cell phone 4 can not burnt because of meeting the water short circuit, thereby has protected chip for cell phone 4.Behind the mobile phone shutdown, can mobile phone be dried the use of can starting shooting.
