Description
Technical field
The utility model relates to field of home appliance technology, specifically a kind of dormancy awakening device for candle lamp.
Background technique
Candle lamp is a kind of lampion, is called novel smokeless type candle lamp, the shape of candle lamp is in real candle phase
Seemingly, but smog or carcinogenic substance will not be generated, it is not only environmentally friendly but also beautiful.Control circuit is embedded in candle lamp,
In control circuit circuit, battery needs to carry out sufficient state-detection to it, to electricity as main supply unit
Pond will carry out charge protection, discharge prevention, and in order to guarantee enough after once charging to use the time.Candle lamp flame not
When work, entire circuit will enter low power consumpting state, battery power consumption be reduced, when extension battery uses after once charging
Between.And after entire circuit enters low power consumpting state, to be also transferred to just according to the variation of external requirement from low power consumpting state
Whether normal working condition, in this process, circuit system single-chip microcontroller need to detect battery status, switch state, have outside to fill
Electric plant-grid connection；Regardless of being to enter dormant state from working condition, or return to working condition from dormant state, require to lead to
The resetting pin RESET of single-chip microcontroller is crossed to realize, under traditional approach, needs to occupy multiple pins of single-chip microcontroller to realize respectively,
But for the single-chip microcontroller used in the candle lamp, since pin number is limited, to realize multiple external status suspend mode and
Wake-up is very difficult, but if is simply to replace single-chip microcontroller, and certainly will increase cost.
Utility model content
The purpose of this utility model is to provide a kind of dormancy awakening device for candle lamp, which can make candle
Lamp realizes the suspend mode and wake-up of two kinds of external status detection on the basis of original single-chip microcontroller, and structure is simple, at low cost.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of dormancy awakening device for candle lamp, including candle lamp single-chip microcontroller, dumping switch, triode Q1, capacitor
C1, C2 and resistance R1, R2, R3, R4；The candle lamp single-chip microcontroller uses TM57PA10A&SOP8, resistance R1 and R2 to be connected on
Between the PA4 foot and GND of candle lamp single-chip microcontroller, the connecting pin of resistance R1 and R2 be separately connected DC charging input anode and
One end of capacitor C2, the base stage of the other end connecting triode Q1 of capacitor C2, the emitter ground connection of triode Q1, triode Q1
Collector connects the RESET foot of candle lamp single-chip microcontroller, and the both ends of resistance R3 are separately connected the collector and emitter of triode Q1；
One end of dumping switch is grounded by resistance R4, and the other end connects the RESET foot of candle lamp single-chip microcontroller；Capacitor C1 connects
It connects between the RESET foot and GND of candle lamp single-chip microcontroller.
The utility model has the beneficial effects that the dumping switch of candle lamp and external dc charging input share a reset
Port makes candle lamp candle lamp can be made by waking up in dormant state when shaking and outside has DC charging input, nothing
Single-chip microcontroller need to be extended, and structure is simple, easy to use, it is at low cost.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is the circuit theory schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, the utility model provides a kind of dormancy awakening device for candle lamp, including candle lamp single-chip microcontroller
MCU1, dumping switch K1, triode Q1, capacitor C1, C2 and resistance R1, R2, R3, R4；The candle lamp single-chip microcontroller uses
TM57PA10A&SOP8, resistance R1 and R2 are connected between the PA4 foot of candle lamp single-chip microcontroller and GND, the connection of resistance R1 and R2
End is separately connected the anode of DC charging input DC and one end of capacitor C2, the base of the other end connecting triode Q1 of capacitor C2
Pole, the emitter ground connection of triode Q1, the collector of triode Q1 connect the RESET foot of candle lamp single-chip microprocessor MCU 1, resistance R3
Both ends be separately connected the collector and emitter of triode Q1；One end of dumping switch K1 is grounded by resistance R4, the other end
Connect the RESET foot of candle lamp single-chip microprocessor MCU 1；Between capacitor C1 connection and the RESET foot and GND of candle lamp single-chip microprocessor MCU 1.
In use process, when shaking candle lamp, dumping switch K1 can of short duration closure, candle lamp single-chip microprocessor MCU 1
RESET foot detects signal, to be waken up from dormant state, when shaking candle lamp again, dumping switch K1 is closed again,
The RESET foot of candle lamp single-chip microprocessor MCU 1 makes candle lamp single-chip microprocessor MCU 1 switch to suspend mode shape by working condition after detecting signal
State.
If external connection DC charging inputs DC, capacitor C2 captures the variation of level, leads triode Q1
It is logical, low level signal is generated to the RESET foot of candle lamp single-chip microprocessor MCU 1, and then calls out candle lamp single-chip microprocessor MCU 1 from suspend mode
It wakes up；After wake-up, the PA4 foot of candle lamp single-chip microprocessor MCU 1 can start to work, to detect the signal of DC charging input DC；When
External dc charge incoming level stablize when, electric current cannot pass through capacitor C2, can not turn-on transistor Q1, candle lamp single-chip microcontroller
MCU1 enters normal work, does not influence other work of RESET foot.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation；Anyone skilled in the art, it is all available in the case where not departing from technical solutions of the utility model ambit
The methods and technical content of the disclosure above makes many possible changes and modifications to technical solutions of the utility model, or is revised as
The equivalent embodiment of equivalent variations.Therefore, all contents without departing from technical solutions of the utility model, according to the utility model
Technical spirit any simple modification, equivalent replacement, equivalence changes and modification made to the above embodiment are still fallen within practical
In the range of the protection of new technique scheme.
