In order for the igniter to operate, power is necessary. Gas water heaters rely heavily on the operating voltage required to supply an igniter to a No. 1 battery. Since the battery is a consumable item, it will be replaced after a period of use. However, because the battery itself does not actively send a warning signal, the gas water heater generally has a weak electric warning device, which can issue a visual warning letter when the battery voltage drops to a preset value, to remind the user to replace the battery in time. If there is no hot water warning device, the user cannot confirm when the battery should be replaced. Generally, when the water heater cannot be started, it is shocked that the battery is dead.

The driving circuit 16 includes a driving unit UC U2 for generating a periodic signal, and its input terminals (VSS and VDD) are respectively connected to the pin 2 of the voltage detecting |C U3 and the output terminal (V0) of the boosting circuit 12, and the output end (LEd) The negative electrode of the light-emitting diode D2 is connected via a resistor R4. In the preferred embodiment, the driver circuit 16 also includes a filter capacitor C3 for connecting the output terminal (V0) of the booster circuit 12 and the pin 2 of the voltage detection 丨C U 3 . Accordingly, when the battery voltage of the input voltage detection 丨C U3 is higher than its preset value (for example, 1_15-1.25V), the pin 2 of the voltage detecting IC U3 will output a high potential of M364900 to the driving IC. U2 keeps the driving IC U2 in a stationary state, and thus cannot drive the light-emitting diode D2 to emit light. At this time, it indicates that the battery power is normal, and the voltage required for the operation of the gas appliance can be supplied. On the contrary, when the battery voltage of the input voltage detecting IC U3 is lower than the preset value, the pin 2 of the voltage detecting IC U3 will output a low (Low) potential to the driving IC U2, so that the driving IC U2 can be operated, thus Outputting a periodic signal to the light-emitting diode D2, so that the light-emitting diode D2 continues to blink, thereby giving the user a visual warning signal, prompting the user to replace the battery in time, avoiding the sudden failure of the gas appliance due to the battery being dead during use. The trouble caused by the flameout. The second figure is the circuit of the second embodiment of the creation. The weak current warning device 1A disclosed in this embodiment comprises a light emitting diode D2, a boosting circuit 12, a voltage detecting circuit 14a and a driving circuit 16a. The light-emitting diode D2 and the boosting circuit 12 are the same as those in the first embodiment, and will not be described again. Here, only the voltage detecting circuit 14a and the driving circuit 16a different from the first embodiment are described as follows: Voltage detecting circuit 14a, comprising two series connected resistors RI and R2 and one transistor Q1, the other end of the resistor R丨 is connected to the positive pole P1 of the battery, the other end of the resistor R2 is grounded; the B pole of the transistor Q1 is connected to the resistors RI and R2 , E pole is grounded. The driving circuit 16a includes a transistor Q2, the B pole of which is connected to the C pole of the transistor Q1, and is connected to the output terminal (V〇) of the boosting circuit 12 via a resistor R3, the E pole is grounded, and the C pole is connected to another resistor. The device R4 is connected to the negative electrode of the light-emitting diode D2. 7 M364900 When the battery voltage is divided by the resistors R1 and R2, if the voltage is higher than the above preset value, the transistor Q1 will be turned on, and the transistor Q2 will be turned off, so that the interrupt driving circuit 16a is connected to the light emitting diode. The circuit of D2 makes the light-emitting diode D2 not emit light. Conversely, if the battery voltage is lower than the preset value, the transistor Q1 will be turned off and the transistor Q2 will be turned on, thereby causing the driving circuit 16a to drive the light-emitting diode D2 to emit the required visual warning signal. In the second embodiment, the driving circuit 16a is connected to the light-emitting diode D2 via the resistor R4 using the C-pole of the transistor Q2, and drives the light-emitting diode D2 to emit light when the transistor Q2 is turned on. However, the second embodiment can also be modified so that the light-emitting diode D2 emits a blinking visual signal as in the first embodiment. The third figure is a circuit of the third embodiment which is changed in accordance with the above. The weak current warning device 1b disclosed in the embodiment, wherein the driving circuit 16b includes a driving IC U2 capable of generating a periodic signal, and the input terminals (VSS and VDD) are respectively connected to the C pole of the transistor Q2 and the boosting circuit 12 The output (VO) and the output (LED) are connected to the negative terminal of the LED D2 through a resistor R4. In this way, when the transistor Q2 is turned on, the driving IC U2 can be operated, and then the driving IC U2 drives the light-emitting diode D2 to generate a periodically blinking visual warning signal. Since the third embodiment only has one more driver IC U2 and one filter capacitor C3 than the second embodiment, the rest are identical, so the same parts of the two embodiments are denoted by the same symbols, and previously for the second implementation. The description of the examples also applies to the third embodiment and will not be described again. The capacitor C3 of this embodiment is connected to the C pole of the transistor Q2 and the output M364900 terminal (vo) of the booster circuit 12. As described above, the gas appliance weakening warning device according to the present invention is suitable for being installed in a gas appliance that supplies a working voltage from a battery, including but not limited to a water heater, to emit a visual warning signal when the voltage of the battery drops to a preset value. Remind the user to replace the battery in time to avoid the gas appliance in the process of use, which is caused by the total fire caused by the battery being dead.
