Preferably, when the duty that said infrared module detects said empty mouse main functional modules was dormant state, controlling said switch module was off-state, cuts off the power supply of said power supply to said empty mouse main functional modules.
Preferably, comprise that also being used for input wakes instruction up, wakes up to said empty mouse main functional modules the key-press module of duty from dormant state.
Preferably, the instruction that wakes up that said infrared module is imported said key-press module detects, and when detecting said when instruction of waking up, controlling said switch module is closure state, connects being connected of power supply and said empty mouse main functional modules.
Preferably, the power consumption of said infrared module is a microwatt level power consumption.
Preferably, said power supply is a battery.
The utility model also proposes a kind of empty mouse; This sky mouse comprises electric power management circuit; Power supply, switch module and infrared module that said electric power management circuit comprises sky mouse main functional modules, said empty mouse main functional modules is supplied power; Said switch module is connected between said power supply and the said empty mouse main functional modules, and said infrared module is connected with the control end and the said empty mouse main functional modules of said switch module; Said infrared module detects the duty of said empty mouse main functional modules, and controls the closure or the off-state of said switch module according to the duty of detected said empty mouse main functional modules.
The electric power management circuit that the utility model proposes; Through in existing empty mouse electric power management circuit, setting up a switch module and an infrared module; Wherein, Infrared module is used for the duty of empty mouse main functional modules is detected, and according to the closure or the off-state of detected duty CS module, thereby the control power supply is to the power supply of empty mouse main functional modules.When the duty that detects sky mouse main functional modules when the infrared ray module is dormant state; Infrared module will be exported control signal corresponding and give switch module; With the CS module is off-state, thereby cuts off the power supply of power supply to empty mouse main functional modules.The utility model can greatly reduce the power consumption of empty mouse when being in dormant state, thereby improves the flying power of its power supply.
Description of drawings
Fig. 1 is the circuit structure block diagram of the utility model electric power management circuit preferred embodiment.
The realization of the utility model purpose, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.
Embodiment
Further specify the technical scheme of the utility model below in conjunction with Figure of description and specific embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 is the circuit structure block diagram of the utility model electric power management circuit preferred embodiment.
With reference to Fig. 1, the utility model electric power management circuit comprises power supply 1, empty mouse main functional modules 2, switch module 3, infrared module 4 and key-press module 5.The utility model electric power management circuit is used for the power management of sky mouse, and certainly, this electric power management circuit also can be used for the power management of other electronic handheld device.
Wherein, One end of switch module 3 is connected with power supply 1; The other end of switch module 3 is connected with empty mouse main functional modules 2, and the detection input end of infrared module 4 is connected with empty mouse main functional modules 2, and the control output end of infrared module 4 is connected with the control end of switch module 3.
Concrete, power supply 1 is used to sky mouse main functional modules 2 WV is provided.Power supply 1 among the utility model embodiment is a battery;
Key-press module 5 is used for input and wakes instruction up, so that empty mouse main functional modules 2 is waken up to duty from dormant state.Wherein, The above-mentioned input that wakes instruction up; The mode that the user both can adopt button to trigger is imported (mode of promptly pressing above-mentioned key-press module 5 is imported); Also can adopt other modes of thinking except that present embodiment to wake the input of instruction up, if guarantee to be imported wake instruction up and can be detected by infrared module 4.
The principle of work of the utility model electric power management circuit specifically describes as follows:
When empty mouse main functional modules 2 is in dormant state; Empty mouse main functional modules 2 will be exported sleep signal; And infrared module 4 can detect the sleep signal of empty mouse main functional modules 2 outputs; When infrared ray module 4 detects the sleep signal of sky mouse main functional modules 2 (duty of empty mouse main functional modules 2 is a dormant state); Infrared module 4 will be exported control signal corresponding and give switch module 3, be off-state with CS module 3, thereby cut off the power supply of 1 pair of empty mouse main functional modules 2 of power supply;
