Description
Technical field
The present invention relates to a kind of detection technique, specifically a kind of super low-power consumption nebulizer plug state inspection。
Background technology
Traditional method is the plug state utilizing electric resistance partial pressure method to detect nebulizer。Cause that power consumption is excessive as selected little resistance can produce higher electric current。As selected bigger resistance, it is possible to reducing power consumption and electric current, electric current is too small, adc or io of mcu cannot detect。
Summary of the invention
It is an object of the invention to provide a kind of high input impedance utilizing comparator or operational amplifier, low current detection characteristic realizes the detection technique of super low-power consumption nebulizer plug state。
For achieving the above object, the present invention provides following technical scheme:
A kind of super low-power consumption nebulizer plug state inspection, including resistance R51, resistance R51, resistance R56, comparator U6 and button SW3, one end of described resistance R51 connects power supply BAT+, resistance R54 and resistance R56, the other end of resistance R54 connects resistance R53 and button SW3, the other end of resistance R51 connects resistance R52 and resistance R54, the other end of button SW3 connects the other end of resistance R52, the earth terminal of comparator U6 and ground, the other end of resistance R53 connects the positive input of comparator U6, the other end of resistance R55 connects the reverse input end of comparator U6, the other end of resistance R56 connects the power end of electric capacity C35 and comparator U6。
Preferred version as the present invention: the resistance of described resistance R51 and resistance R54 is 10M Ω, the resistance of resistance R52 is 50K Ω。
Compared with prior art, the invention has the beneficial effects as follows: the Data Detection that super low-power consumption nebulizer plug state inspection of the present invention is applied in electronic cigarette, there is advantage low in energy consumption, accurate testing。
Accompanying drawing explanation
Fig. 1 is the circuit diagram of super low-power consumption nebulizer plug state inspection。
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments。Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention。
Refer to Fig. 1, in the embodiment of the present invention, a kind of super low-power consumption nebulizer plug state inspection, including resistance R51, resistance R51, resistance R56, comparator U6 and button SW3, one end of described resistance R51 connects power supply BAT+, resistance R54 and resistance R56, the other end of resistance R54 connects resistance R53 and button SW3, the other end of resistance R51 connects resistance R52 and resistance R54, the other end of button SW3 connects the other end of resistance R52, the earth terminal of comparator U6 and ground, the other end of resistance R53 connects the positive input of comparator U6, the other end of resistance R55 connects the reverse input end of comparator U6, the other end of resistance R56 connects the power end of electric capacity C35 and comparator U6。
The resistance of resistance R51 and resistance R54 is 10M Ω, and the resistance of resistance R52 is 50K Ω。
The operation principle of the present invention is: as shown in Figure 1: SW3 regards nebulizer itself as。Comparator or operational amplifier are U6。When nebulizer is plugged, be equivalent to the conducting of SW3 button, U6 the 4th foot output low level。When under nebulizer is dialled, SW3 disconnects, U6 the 4th foot output high level。By the detection of U6 the 4th foot can effectively be judged the plug state of nebulizer, and only need the electric current of nA level。
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when without departing substantially from the spirit of the present invention or basic feature, it is possible to realize the present invention in other specific forms。Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the invention rather than described above limits, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in the present invention。Any accompanying drawing labelling in claim should be considered as the claim that restriction is involved。
In addition, it is to be understood that, although this specification is been described by according to embodiment, but not each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should be made as a whole by those skilled in the art, and the technical scheme in each embodiment through appropriately combined, can also form other embodiments that it will be appreciated by those skilled in the art that。
