Description
Technical field
The utility model provides a kind of human body sensing Rouser of wireless optical mouse, be to utilize the oscillator coil device that is placed in the wireless optical mouse inner control circuit to produce magnetic field, convert changes of magnetic field to change in voltage in order to the detection line device, form the trigger signals of wireless optical mouse central processing unit, trigger signals is waken the wireless optical mouse of complete dormant state up thus; Otherwise if there is not this trigger signals, its wireless optical mouse then is a dormant state, with reach start really, power saving and serviceable life long effect.
Background technology
The power source of wireless optical mouse is to come from battery supplied now, and in order to allow moving of wireless optical mouse can push up very much smooth and not have the reacting to host computer of error, then must come of the optical inductor energy correct induction of driven for emitting lights diode with big electric current by wireless optical mouse, can make that thus the power supply of wireless optical mouse exhausts very soon, for improving the problems referred to above and can the wireless optical mouse of idle state being waken up, the general countermeasure that solves is to use is interrupted detecting, but the method still can power consumption and wireless optical mouse can't really enter dormant state, because of light-emittingdiode is still glimmering, the central processing unit of its wireless optical mouse is also in work.
And general wireless optical mouse mostly there is no other electricity saver and reaches the effect of saving power wastage, it just wastes electric power after putting after a while, and cause sensitivity to reduce, even completely lose function, can operate if will continue to use this wireless mouse then must upgrade electric power again, and the wireless optical mouse that sells on the market only some has electricity saver, see also shown in Figure 4, be that a kind of slide-mouse of commonly using is interrupted the electricity saver of detecting, and this commonly uses main control circuit by a detecting and timing signal, one sleep pattern control circuit, one discontinuous wakes up and the control circuit and a light-emittingdiode driver of timing constitute, wherein discontinuous wakes up and the control circuit of timing is connected to this sleep pattern control circuit, to receive the calling signal of its output, and export a detection signal to the detecting and the control circuit of timing signal, whether move and promptly detect slide-mouse at set intervals, if slide-mouse attonity, its discontinuous wakes up and the control circuit of timing is exported the control circuit of a signal to detecting and timing signal, make the output of sleep pattern control circuit call out signal, in order to cut off the power supply of light-emittingdiode, reach the purpose of saving electric power whereby, but aforesaid way still has following disappearance:
1, its discontinuous wakes up and whether the control circuit of timing need be detected slide-mouse at set intervals and move, still can loss electric power when detecting.
2, the electronic component of its each control circuit uses in long-time discontinuity, causes internal electronic element to damage easily.
Summary of the invention
