Abstract
The utility model discloses a waterproof circuit, comprising a humidity sensor and a triggering shutdown unit. The humidity sensor is connected with the triggering shutdown unit which is connected with an external connection circuit, and the humidity sensor outputs the voltage or the frequency to the triggering shutdown unit. When the voltage or the frequency is higher than the preset value of the triggering shutdown unit, the triggering shutdown unit makes the electric apparatus automatically cut power. The utility model discloses a handset, comprising a humidity sensor and a triggering shutdown unit. The humidity sensor is connected with the triggering shutdown unit which is connected with an external connection circuit, and the humidity sensor outputs the voltage or the frequency to the triggering shutdown unit. When the voltage or the frequency is higher than the preset value of the triggering shutdown unit, the triggering shutdown unit sends out a trigger signal to a power supply circuit which makes the handset cut power, so the circuit of the handset can be protected.

Technique effect of the present utility model is:
(1) when humidity sensor output voltage or frequency are higher than the preset value of circuits for triggering, trigger the shutdown unit and send triggering signal electrical equipment is cut off the power supply automatically, thereby play the purpose of protection appliance circuit.
(2) when humidity sensor output voltage or frequency are higher than the preset value of circuits for triggering, trigger the shutdown unit and send triggering signal mobile phone is cut off the power supply automatically, thereby play the purpose of protection mobile phone circuit.
(3) set up control unit, when selecting non-watertight function, input unit sends a signal and gives control unit, control unit sends control signal to triggering the shutdown unit, trigger the shutdown unit and be in off position, even the mobile phone water inlet can not be played the purpose of waterproof, when selecting water-proof function, input unit sends a signal and gives control unit, control unit sends control signal to triggering the shutdown unit, it is in running order to trigger the shutdown unit, and this mobile phone just can play the purpose of waterproof, thereby freely selects to open or shut water-proof function.The cheap requirement to technology of used electronic component is also lower, thus cost low and be easy to processing.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 the utility model waterproof electrical block diagram;
Fig. 2 the utility model handset structure schematic diagram;
Humidity sensor installation site schematic diagram in Fig. 3 the utility model mobile phone;
Humidity sensor is installed in keyboard bottom surface schematic diagram in Fig. 4 the utility model mobile phone.
Embodiment
Fig. 1 is the utility model waterproof electrical block diagram, and this anti-water circuit comprises humidity sensor 1 and triggering shutdown unit 2, and the output of humidity sensor 1 links to each other with the input that triggers shutdown unit 2, and the output that triggers the unit 2 that shuts down links to each other with appliance circuit.Its operation principle is as follows: humidity sensor 1 output voltage or frequency are to triggering shutdown unit 2; when voltage or frequency are higher than the preset value that triggers the shutdown unit; the output output that triggers shutdown unit 2 triggers off signal cuts off the power supply electrical equipment automatically, thereby plays the purpose of protection appliance circuit.
Fig. 2 is a specific embodiment handset structure of a utility model schematic diagram, comprise power circuit 3, humidity sensor 1 and trigger shutdown unit 2, the output of humidity sensor 1 links to each other with the first input end that triggers shutdown unit 2, the output that triggers shutdown unit 2 links to each other with power circuit 3, also be provided with control unit 4 and input unit 5, the output of this control unit 4 is electrically connected with second input that triggers shutdown unit 2, and the output of input unit 5 links to each other with the input of control unit 4.Wherein, control unit 4 adopts the fundamental frequency processor of mobile phone, and these control unit 4 controls trigger the operating state of shutdown unit 2, and input unit 5 is controlled the operating state that triggers shutdown unit 2 by control unit 4.Wherein, when humidity sensor 1 is voltage output type integrated humidity transducer and employing linear voltage output type integrated humidity transducer, usually be built-in with amplifying circuit at humidity sensor, output and relative humidity are the voltage of proportionate relationship, can adopt the humidity sensor of HIH-4605 of Honeywell company or HIH-4610 type, trigger shutdown unit 2 and send the triggering off signal to power circuit 3, and cause mobile phone outage action immediately according to different voltage; In some cases, humidity sensor may damage, and from then can sending wrong off signal, and under some special situations, the user does not need water-proof function, so can be by input unit 5 free selector switch water-proof functions.Its specific operation process is as follows: the user can select water-proof function or not select water-proof function by the menu on the mobile phone, when the user selects water-proof function by input unit 5, input unit 5 sends a signal and gives control unit 4, control unit 4 sends the operating state that control signal control triggers shutdown unit 2, controls by this control signal and selects water-proof function still not select water-proof function.Input unit 5 can be realized by application layer software by the operating state that control unit 4 controls trigger shutdown unit 2, its course of work is as follows: when the user selects waterproof, input unit 5 sends connection signal and gives control unit 4, and control unit 4 sends control signal and starts water-proof functions for triggering shutdown unit 2.Wherein triggering shutdown unit 2 can realize with a programmable logic device.
