In the present invention, in specific implementation, the first capillary channel network 3 and the second capillary channel network 4 wrap respectively
The more horizontal pipelines 9 and Duo Gen pipe tunnel 10 of cross-distribution are included, to form one for uniformly flowing through and being distributed liquid
The nerve of a covering of metal ensure that effective performance of the radiation-proof effect and effectiveness of liquid metal, avoid blind area.
In specific implementation, it is located at the first capillary channel network 3 and the outermost transverse pipe of the second capillary channel network 4
Road 9 and pipe tunnel 10, caliber are greater than the horizontal pipeline 9 of 4 inside of the first capillary channel network 3 and the second capillary channel network
With pipe tunnel 10.
In the present invention, in specific implementation, it is 15.5 degrees Celsius that fusing point, which can be used, in the liquid metal in the reservoir 1
Gallium-indium-tin alloy.
In the present invention, in specific implementation, the first pipe 5 is identical with the caliber of second pipe 12, is default pipe
The capillary channel of diameter;
The caliber of the first pipe 5 and second pipe 12 is less than the caliber of major flow pipeline 11.
Therefore, the capillary force that can make full use of first pipe 5 and second pipe 12, is drawn into liquid metal
In first pipe 5 and second pipe 12.
In the present invention, in specific implementation, the caliber of major flow pipeline 11 is greater than the pipe of horizontal pipeline 9 and pipe tunnel 10
Diameter, and the caliber of horizontal pipeline 9 is greater than the caliber of pipe tunnel 10.
In the present invention, in specific implementation, the first main connecting pipe 81, the second main connecting pipe 82 and the main connecting tube of third
The caliber in road 83 is identical, and the caliber of major flow pipeline 11 is greater than their caliber;
The caliber of first main connecting pipe 81, the second main connecting pipe 82 and the main connecting pipe 83 of third is greater than horizontal pipeline
9 caliber.
For the present invention, it should be noted that reservoir 1: in not enabled radiation protection and the effect of electromagnetic shielding, playing
The effect of temporary storing liquid metal, passes through the first main connecting pipe 81, the second main connecting pipe 82 and the main connecting pipe of third
83 and second pipe 12 be connected with the pipeline in external the first capillary channel network 3 and the second capillary channel network 4,
And accordingly setting switchs in connecting pipe.
Intelligent switch 2, when detecting that mobile phone receives starting call instruction for microcontroller, triggering starts the switch,
First main connecting pipe 81 where the switch is located at bottom, for connecting reservoir.
First capillary channel network 3 and the second capillary channel network 4, are made of rigid non-metallic material respectively, are hollow
Piping network.Wherein, the first capillary channel network 3 is placed in after mobile phone screen.When flow of liquid metal is fashionable, electricity can be played
The effect of magnetic screen.Second capillary channel network 4, is placed in front of mobile phone battery cover, when flow of liquid metal is fashionable, can play electromagnetism
The effect of shielding.
More first pipes 5 are the superfine capillary channel of caliber, when liquid metal is located at 3 He of the first capillary channel network
When preparing to flow back to reservoir 1 in the second capillary channel network 4, its biggish capillary force will be utilized, liquid metal will be sucked.
Second pipe 12 is the superfine capillary channel of caliber, when liquid metal in major flow pipeline 11 by gravity
And when flowing down, it will be inhaled into, finally be flowed back in reservoir 1 by its biggish capillary force.
Major flow pipeline 11 utilizes the capillary of first pipe 5 when liquid metal flows back to reservoir 1 for thicker pipeline
Force flow enters wherein, then, makes liquid toward flowing down first with gravity, secondly utilizes the capillary force of second pipe 12, so that
Liquid metal flows back to reservoir 1.
First switch 6, opening when receiving stopping electromagnetic shielding instruction for microcontroller.When the end of conversation of mobile phone,
Also this switch is triggered to open.
Second switch 7 and third switch 13, when being used to microcontroller and receiving starting electromagnetic shielding instruction, two switches are same
When open.The second main connecting pipe 82 and the main connecting pipe 83 of third are located at bottom where two switches, for connecting reservoir.
In order to which the present invention is more clearly understood, illustrate two kinds of working conditions of the invention below.
One, mobile phone communication radiation protection working condition.
Liquid metal is originally located in reservoir, and each switch is in close state, when the user of mobile phone triggers call
When, while triggering and opening intelligent switch 2.The capillary force having using the first main connecting pipe 81 as capillary, liquid metal
In the first capillary channel network 3 after being inhaled into mobile phone screen, thus to the high-strength magnetic spoke generated in mobile phone communication process
Largely shielding action is penetrated.
When user terminates call, first switch 6 is opened, and intelligent switch 2 is closed.The capillary of superfine first pipe 5
Power is bigger, then liquid metal is driven to flow into thick major flow pipeline 11, the liquid gold flowed into using gravity
Category flows downward.There is a superfine second pipe 12 in the bottom of major flow pipeline 11, both ends are respectively used to connection major flow
Pipeline 11 and reservoir 1.The biggish capillary force for utilizing this pipeline again, flows back to liquid metal in reservoir, turns off the switch.
Two, shielding mobile phone electromagnetism working condition.
When the demand of triggering electromagnetic shielding, second switch 7 and third switch 13 are opened, using compared with thin pipe (i.e. second
Main connecting pipe 82 and the main connecting pipe 83 of third) capillary force, liquid metal be inhaled into front and back (i.e. first mao of reticular structure
Thin pipe network 3 and the second capillary channel network 4) in, second switch 7 and third switch 13 are opened.
When mobile phone receives the instruction for terminating electromagnetic shielding, all first switches 6 are opened, and second switch 7 and third are opened
13 are closed to close.The capillary force of superfine first pipe 5 is bigger, then flow of liquid metal is driven to become owner of in conduction pipe 11, benefit
With gravity, the liquid metal flowed into flows downward.There is a second superfine pipe in the bottom of major flow pipeline 11
Road 12, both ends are respectively used to connection major flow pipeline 11 and reservoir 1.The biggish capillary force for utilizing this pipeline again, makes liquid
State metal flows back in reservoir, turns off the switch.
Compared with prior art, the present invention is due to taking above technical scheme, with advantageous effects below:
1, can guarantee mobile phone can normal talking under the premise of, to the spoke of human body when being greatly reduced mobile phone communication
It penetrates, continuous escort, feels at ease to converse.
2, object user is this huge group of the owner of mobile phone.
3, the potential radiation to human body of cellular phone signal shielding device is improved:
4, the object of shielding, the time of shielding and duration has accurately been determined, other people communication will not be upset.
In conclusion compared with prior art, a kind of mobile phone safe protection based on liquid metal provided by the invention
Device, scientific structure design is reasonable, by cooperating with mobile phone, using the mobility and electromagnetic shielding characteristic of liquid metal, both
Can the radiation protection when user holds mobile phone communication, and can satisfy user to the electromagnetic shielding demand of mobile phone, can significantly increase
User is added to be conducive to be widely applied, be of great practical significance the product use feeling of mobile phone.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
