[0023] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.
[0024] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0025] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.
[0026] An embodiment of this utility model provides a power supply circuit powered by a hydroelectric generator, such as... Figure 1 As shown, the system includes a hydroelectric generator 100, a voltage regulator module 200, a charging module 300, a battery 400, and a protection module 500. The hydroelectric generator 100 is placed in the water circuit of the water heater. When water flows in the circuit, the hydroelectric generator 100 generates electricity, producing a voltage signal. The hydroelectric generator 100 is connected to the input terminal of the voltage regulator module 200, and the voltage signal generated by the hydroelectric generator 100 is transmitted to the voltage regulator module 200. The voltage regulator module 200 stabilizes the voltage, and its output terminal outputs a relatively stable voltage signal. The output terminal of the voltage regulator module 200 is connected to the charging module 300, thereby transmitting the stable voltage signal to the charging module 300. The charging module 300 is connected to the positive terminal of the battery 400 to charge the battery 400. The charging module 300 also manages the charging of the battery 400. Therefore, the hydroelectric generator can generate electricity and charge the battery 400, which can extend the battery 400's range and eliminate the need for users to frequently replace the battery 400, thus improving the user experience.
[0027] The protection module 500 is connected with the positive electrode and the negative electrode of the battery 400, and is used for overcharge protection and / or overdischarge protection of the battery 400, so as to avoid damage of the battery 400 or a load connected with the battery 400 due to overvoltage, and improve the safety of use.
[0028] In the embodiment, the battery 400 can be a dry battery according to actual needs.
[0029] In some embodiments, as shown in Figure 2 The voltage stabilizing module includes a chip TPS60370, the 12th pin and the 13th pin of the chip TPS60370 are input ends of the voltage stabilizing module and are connected with the hydraulic generator. The 1st pin, the 4th pin, the 6th pin and the 10th pin of the chip TPS60370 are grounded; the 12th pin of the chip TPS60370, the third resistor R3 and the 14th pin of the chip TPS60370 are connected, and the 14th pin and the 15th pin of the chip TPS60370 are connected; the 3rd pin of the chip TPS60370 is grounded through the fifth capacitor C5; the 11th pin of the chip TPS60370, the first inductor L1 and the 9th pin of the chip TPS60370 are sequentially connected; the 5th pin, the 7th pin and the 8th pin of the chip TPS60370 are connected with the anode of the first diode D1, and the cathode of the first diode is an output end of the voltage stabilizing module; the 2nd pin of the chip TPS60370, the second resistor R2 and the anode of the first diode are sequentially connected.
[0030] The voltage stabilizing module of the embodiment can stabilize the input voltage of 3-16V to 5V output to meet the needs of the subsequent circuit.
[0031] In order to filter out impurity waves, the 12th pin of the chip TPS60370 can be connected with a filter capacitor C3. The 8th pin of the chip TPS60370 can also be connected with filter capacitors C1 and C2.
[0032] In some embodiments, as shown in Figure 3 The charging module includes a chip TP4056; the 1st pin and the 3rd pin of the chip TP4056 are grounded; the 2nd pin of the chip TP4056 is grounded through the fifth resistor R5; the 4th pin and the 8th pin of the chip TP4056 are connected with the output end of the voltage stabilizing module; and the 5th pin of the chip TP4056 is connected with the positive electrode of the battery BT1.
[0033] The charging current of the chip TP4056 is relatively high, which is better for the battery. The 4th pin of the chip TP4056 is an enable pin, when the 4th pin is high, the whole chip works, and when the 4th pin is low, the whole chip stops working. The 1st pin of the chip TP4056 can detect the temperature of the chip TP4056, and when the temperature of the chip is abnormal, the chip TP4056 will stop charging.
[0034] Furthermore, the charging module also includes a first resistor R1, a fourth resistor R2, a first indicator light, and a second indicator light; the output terminal Vin of the voltage regulator module, the first indicator light, the first resistor, and pin 7 of the TP4056 chip are connected in sequence; the output terminal Vin of the voltage regulator module, the second indicator light, the fourth resistor, and pin 6 of the TP4056 chip are connected in sequence.
[0035] The first and second indicator lights can be used to indicate the battery's charging status. When the first indicator light is on and the second indicator light is off, it means the battery is being charged; when the first indicator light is off and the second indicator light is on, it means charging is complete; when both the first and second indicator lights are off, it indicates an abnormality such as low voltage, excessively high battery temperature, excessively low battery temperature, or no connection to the battery. This allows users to understand the battery's charging status and make timely adjustments.
[0036] In some embodiments, such as Figure 1 As shown, the charging module 300 is also connected to a backup charging interface 600. When the voltage generated by the hydroelectric generator 100 is too low and the power of the battery 400 is too low, the electrical energy provided by the hydroelectric generator 100 and the battery 400 cannot power the load. In this case, the backup charging interface 600 can be connected to an external power source to power the load and charge the battery 400, thus ensuring the normal operation of the load.
[0037] The backup charging port 600 can be a USB port, a Lightning port, a DC round port, or another type of port.
[0038] In some embodiments, such as Figure 3 As shown, the protection module includes chip DW01-A, third MOSFET Q3, and fourth MOSFET Q4. The positive terminal of the battery, the eighth resistor R8, and pin 5 of chip DW01-A are connected sequentially. Pin 5 of chip DW01-A, the sixth capacitor C6, and pin 6 of chip DW01-A are connected sequentially. Pin 1 of chip DW01-A is connected to the gate of the third MOSFET, pin 3 of chip DW01-A is connected to the gate of the fourth MOSFET, and pin 2 of chip DW01-A is grounded through the twelfth resistor R12. The negative terminal of the battery is connected to the source of the third MOSFET, the drain of the third MOSFET is connected to the drain of the fourth MOSFET, and the source of the fourth MOSFET is grounded. Both the third and fourth MOSFETs can be N-type MOSFETs.
[0039] In the normal state, the voltage of the 5th pin of the chip DW01-A is between the overvoltage charging protection threshold (VOC) and the overvoltage discharging protection threshold (VOD), and the voltage of the VM detection end is between the charging detection voltage (VCHG) and the overcurrent discharging protection threshold (VEDI). At this time, the 1st pin and the 3rd pin of the chip DW01-A both output high level, so that the two external MOS tubes are turned on. This means that the battery can be charged and discharged through the load.
[0040] The chip DW01-A performs overcharge / discharge protection by detecting the voltage of VDD or VM. When the overcharge / discharge protection condition occurs, the 1st pin and the 3rd pin of the chip DW01-A change from high level to low level, so that the two MOS tubes change from conduction to cut-off, and the charging / discharging process stops.
[0041] In some embodiments, as shown in Figure 4 The power supply circuit powered by the hydraulic generator further includes an enabling module 700, a switch module 800 and a power consumption module 900. The positive electrode of the battery 400, the switch module 800 and the power consumption module 900 are connected in sequence, and the enabling module 700 is connected with the hydraulic generator 100 and the switch module 800 respectively. The enabling module 700 can control the switch module 800 to be turned on or turned off according to the voltage generated by the hydraulic generator 100. When the voltage generated by the hydraulic generator 100 is lower than the preset voltage, the enabling module 700 is used to control the switch module 800 to be turned off, so that the battery 400 cannot supply power to the power consumption module 900, and the power consumption module 900 stops working. When the voltage generated by the hydraulic generator 100 is greater than or equal to the preset voltage, the enabling module 700 is used to control the switch module 800 to be turned on, so that the battery 400 supplies power to the power consumption module 900, and the power consumption module 900 starts working.
[0042] Since the voltage generated by the hydraulic generator 100 is related to the flow rate of water, the faster the flow rate of water, the greater the voltage generated by the hydraulic generator 100, and vice versa. Therefore, the voltage generated by the hydraulic generator 100 is positively correlated with the flow rate of water, so that the hydraulic generator 100 can replace the water flow sensing switch.
[0043] In the embodiment, the power consumption module 900 can include an igniter control module. When the voltage generated by the hydraulic generator 100 is lower than the preset voltage (for example, 4.7V), the igniter control module controls the gas valve of the water heater to be closed, so that the water heater stops boiling water. When the voltage generated by the hydraulic generator 100 is greater than or equal to the preset voltage, the igniter control module controls the gas valve of the water heater to be opened.
[0044] Further, as shown in Figure 5As shown, the switch module comprises a chip XC6204, the 1 pin of the chip XC6204 is connected with the positive pole of the battery, the 2 pin of the chip XC6204 is grounded, the 3 pin of the chip XC6204 is connected with the enable module, and the 5 pin of the chip XC6204 is connected with the power consumption module.
[0045] The 3 pin of the chip XC6204 is used as an enable end, when the 3 pin receives a low level signal, the 5 pin of the chip XC6204 outputs a voltage, when the 3 pin receives a high level signal, the 5 pin of the chip XC6204 does not output a voltage, thereby playing a role of a switch.
[0046] Further, as shown, Figure 5 The enable module comprises a voltage stabilizing diode D4, a first triode Q1 and a second triode Q2, the voltage stabilizing diode D4, the first triode Q1 and the second triode Q2 form a threshold detection circuit, which is used for detecting whether the voltage generated by the hydraulic generator is lower than a preset voltage (for example, 4.7V).
[0047] The negative pole of the voltage stabilizing diode is connected with the hydraulic generator, the positive pole of the voltage stabilizing diode, the tenth resistor R10 and the base of the second triode are sequentially connected, the positive pole of the voltage stabilizing diode, the eleventh resistor R11 and the emitter of the second triode are sequentially connected, and the emitter of the second triode is grounded; the output end of the voltage stabilizing module, the sixth resistor R6 and the collector of the second triode are sequentially connected; the collector of the second triode, the seventh resistor R7 and the base of the first triode are sequentially connected, the output end of the voltage stabilizing module is connected with the emitter of the first triode, the collector of the first triode is connected with the 3 pin of the chip XC6204, and the collector of the first triode is grounded through the ninth resistor R9. The first triode can be a PNP diode, and the second triode can be an NPN diode.
[0048] When the voltage generated by the hydraulic generator is lower than the preset voltage, the voltage stabilizing diode is not conductive, the collector of the first triode outputs a high level signal, and the 5 pin of the chip XC6204 does not output a voltage to the power consumption module. When the voltage generated by the hydraulic generator is greater than or equal to the preset voltage, the voltage stabilizing diode is conductive, the collector of the first triode outputs a low level signal, and the 5 pin of the chip XC6204 outputs a voltage to the power consumption module.
[0049] The embodiment of the utility model provides a water heater, including any one of the above-mentioned embodiment through the power supply circuit of hydraulic generator power supply, the specific description of the power supply circuit of hydraulic generator power supply can refer to the above-mentioned embodiment, and here is not repeated.

Accordingly, it should be apparent to those skilled in the art that the above description of various embodiments of the present application is provided only to explain the present application and it would not be construed as limiting the present application as defined by the appended claims and their equivalents.
