Description
Technical field
The utility model relates to home furnace technical field, particularly relates to a kind of battery allowance alarm set for gas-cooker.
Background technology
At present, household gas range generally uses dry cell power supply, and user in use, when battery electric quantity is not enough, can cause kitchen range in family to light a fire.Because user can not prepare battery usually ahead of time, when cannot light a fire appears in gas-cooker, also cannot judge it is that priming supply undertension or whole gas kitchen ranges break down on earth.According to market survey, because gas kitchen ranges battery electric quantity is not enough, unexpected inoperable wrong report fault account for more than 30% of the repair a breakdown rate of producer, causes larger puzzlement to gas kitchen ranges manufacturer, dealer and user.
For this reason, in the industry someone one is proposed can at battery electric quantity close to before exhausting, send signal ignition controller early, if one section of publication number is the Chinese invention patent application of CN104006419A, disclose the ignition controller that a kind of battery powered gas-cooker is used, be provided with the single-chip microcomputer of battery, direct current power source voltage voltage boosting and stabilizing circuit and band A/D mouth, the A/D mouth of this direct current power source voltage voltage boosting and stabilizing circuit input and anode and single-chip microcomputer is electrically connected, and supply voltage voltage boosting and stabilizing circuit output is connected with microcontroller power supply input; When gas-cooker is in non-ignition state and/or magnetic valve is in non-action status, when single-chip microcomputer detects that cell voltage is 0.7 ~ 0.8 times of its rated value by A/D mouth, drive warning circuit work.Although this ignition controller has battery electric quantity measuring ability, it relies on the built-in program of single-chip microcomputer, and structure is more complicated, and manufacturing cost is higher, safeguards inconvenience.
Summary of the invention
For problems of the prior art, the purpose of this utility model is to provide the gas-cooker battery allowance alarm set that a kind of structure is simple, be with deixis.
For reaching above object, the utility model adopts following technical scheme.
For a battery allowance alarm set for gas-cooker, it is characterized in that, comprising: testing circuit, signal processing circuit, display unit; Described testing circuit detects cell voltage, and processes, this voltage margin signal feeding signal processing circuit when signal processing circuit judges battery electric quantity lower than required value, by output drive signal to display unit.
Further illustrating as such scheme, described display unit is indicator lamp.
Further illustrating as such scheme, described battery allowance alarm set comprises: four resistance, two triodes and a light emitting diode;
First resistance R1 and the second resistance R2 is connected between the both positive and negative polarity of battery, the base stage of the first triode Q1 is connected with the node of the first resistance R1 and the second resistance R2, the emitter stage of the first triode Q1 is connected with GND, and the colelctor electrode of the first triode is connected with anode by the 3rd resistance R3; The base stage of the second triode Q2 is connected with the colelctor electrode of the first triode Q1, and the emitter stage of the second triode Q2 is connected with GND, and the colelctor electrode of the second triode Q2 is connected with anode by diode D, the 4th resistance R4.
Further illustrating as such scheme, is connected with microswitch between testing circuit and battery.
Further illustrating as such scheme, the knob ignition switch of described microswitch gas-cooker replaces.
A kind of battery allowance alarm set for gas-cooker that the utility model provides, during real work, testing circuit detects cell voltage, and this voltage margin signal feeding signal processing circuit is processed.When signal processing circuit judges battery electric quantity lower than required value, by output drive signal, drive display unit lightening LED lamp.Like this, when kitchen range electricity is not enough, user can be clear that prompting, is convenient to user and changes battery use, practical.
Accompanying drawing explanation
Figure 1 shows that the battery allowance alarm set structured flowchart that the utility model provides;
Figure 2 shows that the battery allowance alarm set circuit diagram that the utility model provides.
Detailed description of the invention
For setting forth essence of the present utility model further, by reference to the accompanying drawings detailed description of the invention of the present utility model is described as follows.
As shown in Figure 1, a kind of battery allowance alarm set for gas-cooker, comprising: testing circuit 1, signal processing circuit 2, display unit 3.Described testing circuit 1 detects battery allowance and battery allowance signal is sent into signal processing circuit 2.When signal processing circuit 2 judges that battery allowance is not enough to use, drive the display unit 3 in display unit to carry out electricity deficiency and remind.
As shown in Figure 2, described testing circuit 1 and signal processing circuit 2 are made up of four resistance and two triodes, and described display unit 3 is light emitting diode.Particularly, the annexation of each electronic devices and components is: the first resistance R1 and the second resistance R2 is connected between the both positive and negative polarity of battery, the base stage of the first triode Q1 is connected with the node of the first resistance R1 and the second resistance R2, the emitter stage of the first triode Q1 is connected with GND, and the colelctor electrode of the first triode is connected with anode by the 3rd resistance R3; The base stage of the second triode Q2 is connected with the colelctor electrode of the first triode Q1, and the emitter stage of the second triode Q2 is connected with GND, and the colelctor electrode of the second triode Q2 is connected with anode by diode D, the 4th resistance R4.
Like this, in gas-cooker real work, when battery allowance is a lot, then the first triode Q1 conducting, the base earth of the second triode Q2, the second triode Q2 ends, and light emitting diode D is not lit; When battery allowance is not enough, the first triode Q1 ends, and at this moment the second triode Q2 is switched on, and light emitting diode D lights, and reaches the object of pilot cell surplus.
Especially, for avoiding the electricity of battery allowance alarm set loss battery always, between testing circuit and battery, microswitch K is connected with.In the present embodiment, preferred microswitch K is that the knob ignition switch of gas-cooker replaces.
Above detailed description of the invention has been described in detail essence of the present utility model, but can not limit protection domain of the present utility model with this.Apparently, under the enlightenment of the utility model essence, the art those of ordinary skill also can carry out many improvement and modification, it should be noted that these improve and modify and all drops within claims of the present utility model.
