Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to electronic cigarettes, charging panels, and solar charging control circuits. Background Technology

[0002] In related technologies, e-cigarettes typically use polymer lithium batteries as their power source. When fully charged, polymer lithium batteries can provide users with several minutes of continuous vaping. The battery life of traditional polymer lithium batteries is insufficient to meet the needs of users for multiple vaping sessions. When the battery is depleted, it requires a power source (such as AC power or a USB power bank) to recharge. When users are outdoors or do not have a portable charger, they will be unable to recharge their e-cigarettes, causing significant inconvenience to their vaping experience.

[0003] Currently, no effective solution has been proposed to address the problem of inconvenient charging and poor user experience when electronic cigarettes are used outdoors and run out of power. Utility Model Content

[0007] The push-button switch is used to control the connection and disconnection between the control terminal of the switch circuit and the first power supply.

[0008] The switching circuit is used to generate a preset low-level first switching signal when the control terminal of the switching circuit is connected to the first power supply, and to generate a preset high-level first switching signal when the control terminal of the switching circuit is disconnected from the first power supply.

[0009] When the level of the first switch signal is a preset low level, the solar boost module is turned off to stop charging the lithium battery. When the level of the first switch signal is a preset high level, the solar boost module is turned on to convert the photovoltaic voltage into a charging voltage for charging the lithium battery.

[0026] Figure 1 This is a structural block diagram of the solar charging control circuit according to an embodiment of this application. Figure 2 This is a structural block diagram of the solar charging control circuit according to a preferred embodiment of this application. Figure 3 This is a topology diagram of the solar charging control circuit according to an embodiment of this application. The solar charging control circuit is used for the charging plate of the electronic cigarette. Through the solar charging control circuit, the corresponding charging voltage is provided to the lithium battery that drives the electronic cigarette, realizing the charging of the electronic cigarette by solar energy. This changes the charging method that previously required a charging cable, improving the user experience when using it outdoors.

[0027] Please see Figures 1 to 3 The solar charging control circuit of this application embodiment is used for a charging plate of an electronic cigarette, including a perovskite thin film 100, a switching module 200, a solar boost module 300, a main control unit 400, and a lithium battery 500. The output terminal of the perovskite thin film (100) is coupled and electrically connected to the input terminal 301 of the solar boost module 300. The control terminal 302 of the solar boost module 300 is coupled and electrically connected to the output terminals of the main control unit 400 and the switching module 200, respectively. The output terminal 303 of the solar boost module 300 is electrically connected to the lithium battery 500.

[0028] Perovskite thin film 100 is used to generate the corresponding photovoltaic voltage.

[0029] In this embodiment, the perovskite thin film 100 serves as the corresponding solar cell, converting solar energy into corresponding energy, which is then boosted by the solar boost module 300 to a voltage used to charge the lithium battery 500.

[0030] The switching module 200 is used to generate and send a first switching signal to the solar boost module 300.

[0031] In this embodiment, the switch module 200 generates a corresponding switch signal (corresponding to the first switch signal) based on the user's switch selection to control the start or stop of the solar boost module 300. In this embodiment, when the user turns on charging via the switch, the switch module 200 generates the first switch signal to control the start of the solar boost module 300. At this time, the perovskite frame film 100, in conjunction with the solar boost module 300, provides the corresponding charging voltage to the lithium battery 500. When the user turns off charging via the switch, the switch module 200 generates the first switch signal to control the shutdown of the solar boost module 300. At this time, the solar boost module 300 stops outputting the corresponding charging voltage.

[0032] The main control unit 400 is used to output a second switching signal to the solar boost module 300.

[0033] In this embodiment, the main control unit 400 can be a microcontroller (MCU), a digital signal processor (DSP), or a programmable logic device (FPGA). In some optional embodiments, the main control unit 500 is preferably an MCU of one of the following: R7F0C908B2 microprocessor, STC15F204 microcontroller, AT89S52 microcontroller, or EN8F677E microprocessor.

[0034] In this embodiment, the main control unit 400 detects the working status of the solar boost module 300, and when it detects that the solar boost module 300 is in a preset abnormal state (e.g., overvoltage, overcurrent, overtemperature), it generates a corresponding second switch signal to control the solar boost module 300 to shut down. After that, after a preset shutdown time, the main control unit 400 outputs a second switch signal to drive the solar boost module 300 to start working.

[0035] The solar boost module 300 is used to start and stop according to the corresponding first and second switch signals, so as to convert the photovoltaic voltage into the charging voltage for charging the lithium battery 500.

[0036] In this embodiment, the solar boost module 300 controls its start-up and stop operation based on one of the first and second switch signals received under different states. In this embodiment, after the solar boost module 300 is started for charging by outputting the first switch signal through the switch module 200, the solar boost module 300 is in the start-up state and does not need to be frequently operated. When the solar boost module 300 is in the start-up state, the corresponding first switch signal can be output through the switch module 200 to control the solar boost module 300 to be in the off state, or the corresponding second switch signal can be output through the main control unit 400 to control the solar boost module 300 to be in the off state. However, when the switch module 200 controls the solar boost module 300 to be in the off state, the main control unit 400 cannot control the solar boost module 300 to start by outputting the corresponding second switch signal.

[0037] In the aforementioned solar charging control circuit, a corresponding photovoltaic voltage is generated by the perovskite thin film 100. A first switching signal is generated by the switching module 200 and sent to the solar boost module 300. A second switching signal is output to the solar boost module 300 by the main control unit 400. The solar boost module 300 starts and stops according to the corresponding first and second switching signals to convert the photovoltaic voltage into a charging voltage for the lithium battery. This solves the problem of inconvenient charging and poor user experience when the battery of an electronic cigarette is depleted during outdoor use. By controlling the start and stop of the solar boost module 300 through the switching module 200, the solar boost module 300 works with the perovskite thin film 100 to charge the lithium battery 500, achieving the beneficial effect of controlling charging according to demand and facilitating outdoor charging of electronic cigarettes.

[0038] To control the start and stop operation of the solar charging control circuit, refer to... Figures 1 to 3 In some embodiments, the switch module 200 includes a push-button switch 21 and a switch circuit 22. One end of the push-button switch 21 is electrically connected to both a first power supply and the input terminal of the switch circuit 22. The other end of the push-button switch 21 is electrically connected to the control terminal of the switch circuit 22. The output terminal of the switch circuit 22 is connected to the output terminal of the switch module 200.

[0039] The push-button switch 21 is used to control the connection and disconnection between the control terminal of the switch circuit 22 and the first power supply.

[0040] In this embodiment, the push button switch 21 serves as the corresponding control switch to enable or disable the control switch circuit 22. That is, when the push button switch 21 is pressed (corresponding to selecting to turn on the charging function), the control terminal of the switch circuit 22 receives the corresponding start signal, and when the push button switch 21 is pressed to turn off the charging function, the control terminal of the switch circuit 22 receives the corresponding power off signal.

[0041] The switching circuit 22 is used to generate a preset low-level first switching signal when the control terminal of the switching circuit 22 is connected to the first power supply, and to generate a preset high-level first switching signal when the control terminal of the switching circuit 22 is disconnected from the first power supply.

[0042] In this embodiment, when the button switch 21 is pressed to turn on the charging function, the control terminal of the switch circuit 22 receives a corresponding high level. At this time, the switch circuit 22 generates a first switch signal with a corresponding preset low level. In this embodiment, when the button switch 21 is pressed to turn off the charging function, the control terminal of the switch circuit 22 receives a corresponding low level. At this time, the switch circuit 22 generates a first switch signal with a corresponding preset high level. In this embodiment, the first switch signal with a preset low level corresponds to the switch signal for turning off the charging function, and the first switch signal with a preset high level corresponds to the switch signal for turning on the charging function.

[0043] When the level of the first switch signal is at a preset low level, the solar boost module 300 is turned off to stop charging the lithium battery 500. When the level of the first switch signal is at a preset high level, the solar boost module 300 is turned on to convert the photovoltaic voltage into a charging voltage for charging the lithium battery 500.

[0044] In this embodiment, by pressing the button switch 21, the button switch 21 connects or disconnects the first power supply from the control terminal of the switch circuit 22, thereby controlling the switch circuit 22 to be turned on or off. And by turning the switch circuit 22 on or off, the solar boost module 300 is started or turned off.

[0045] To further control the solar charging control circuit, refer to Figure 3 The switching circuit 22 includes a switching transistor Q1, which includes a first control terminal, a first input terminal, and a first output terminal. The first control terminal is connected to the push-button switch 21 (reference) through a first resistor R6 in series. Figure 3 One end corresponding to K1 in the diagram is electrically connected. The first input terminal is electrically connected to the first power supply (corresponding to a +5V power supply, and this +5V output can be the output of a 500 lithium battery) through a series second resistor R7. The electrical connection point between the first input terminal and the second resistor R7 is electrically connected to the output terminal of the switch circuit 22 (see reference) through a series first coupling resistor R8. Figure 3The network label (XS) is used, and the first output terminal is connected to ground.

[0046] In this embodiment, the first coupling circuit R8 is electrically connected to a filter capacitor C5 away from the connection point of the second resistor R7, and a bypass filter capacitor C4 is provided between the first control terminal and the first output terminal of the switching transistor Q1.

[0047] When the push-button switch 21 connects the control terminal of the switching circuit 22 to the first power supply, the switching transistor Q1 is turned on and used to control the connection between the first input terminal and the first output terminal. When the push-button switch 21 disconnects the control terminal of the switching circuit 22 from the first power supply, the switching transistor Q1 is turned off and used to control the disconnection between the first input terminal and the first output terminal.

[0048] In this embodiment, when the switch Q1 is turned on, the first input terminal is connected to the first output terminal. The electrical connection point between the second resistor R7 and the first input terminal is at the same potential as the first output terminal. Since the first output terminal is to ground, the electrical connection point between the second resistor R7 and the first input terminal is also to ground and is at a low level. At this time, the other end of the first coupling resistor R8 is also at a low level. When the switch Q1 is turned off, the first input terminal is disconnected from the first output terminal. The electrical connection point between the second resistor R7 and the first input terminal is pulled up and set to a high level. In other words, the electrical connection point between the second resistor R7 and the first input terminal is at a high level. At this time, the other end of the first coupling resistor R8 is also at a high level.

[0049] In this embodiment, the push-button switch 21 includes one of the following: a membrane push-button switch, a tactile push-button switch, or a toggle switch.

[0050] When the first input terminal is connected to the first output terminal, the switching circuit 22 outputs a preset low-level first switching signal along its output terminal; when the first input terminal is disconnected from the first output terminal, the switching circuit 22 outputs a preset high-level first switching signal along its output terminal.

[0051] It should be noted that the switching transistor Q1 in the embodiments of this application includes, but is not limited to, transistors, MOSFETs, and field-effect transistors. Furthermore, based on the disclosure of this application, those skilled in the art can easily conceive of modifying the switching transistor disclosed in this application into a switching circuit 22 that is adapted to the specific selection of the switching transistor. Therefore, this application can be implemented regardless of whether the switching transistor is an NPN or PNP transistor, an N-channel or P-channel switching MOSFET, or an N-type or P-type field-effect transistor. This application is not limited in the embodiments of this application. For example, in the embodiments of this application, the switching transistor can be a BC846C type transistor.

The power setting port MPP-SET of the SPV1040 solar charging chip U1 is electrically connected to the input terminal 301 of the solar boost module 300. The inductor connection port LX of the SPV1040 solar charging chip U1 is electrically connected to the input terminal 301 of the solar boost module 300 via a series first inductor L1. The start / stop control port XSHUT of the SPV1040 solar charging chip U1 is connected to the control terminal 302 of the solar boost module 300. The output terminal VOUT of the SPV1040 solar charging chip U1 is electrically connected to the output terminal 303 of the solar boost module 300 via a series sensing resistor R5. The current detection control port of the SPV1040 solar charging chip U1 (see reference)... Figure 3 The PLUS and MINUS ports of U2 are electrically connected to the first and second terminals of the sensing resistor R5 via the first sampling resistor R1 and the second sampling resistor R2 in series. The voltage detection and control port UCTRL of the SPV1040 solar charging chip U1 is electrically connected to the third resistor R3 and the fourth resistor R4. The other end of the third resistor R3 is electrically connected to the output terminal 303 of the solar boost module 300. The other end of the fourth resistor R4 is grounded. The third resistor R3 and the fourth resistor R4 form a corresponding voltage divider sampling circuit.

[0053] In this embodiment, the SPV1040 solar charging chip U1 is a low-power, low-voltage fully integrated boost converter with an input voltage range of 0.3 V to 5.5 V. It maximizes the utilization of energy generated by the perovskite thin film 100. The SPV1040 solar charging chip U1 can extract energy from the perovskite thin film 100 and transfer it to the output terminal even under constantly changing environmental conditions, achieving the highest efficiency conversion. Simultaneously, the SPV1040 solar charging chip U1 employs a voltage regulation loop composed of resistors R1, R2, R3, R4, and R5, using resistor voltage division (reference...). Figure 3 The SPV1040 solar charging chip U1 uses R3 and R4 to fix the rechargeable battery voltage; it provides controlled output voltage and current by sensing the VCTRL feedback signal generated by the voltage division of R3 and R4 respectively and the voltage drop across the sensing resistor R5.

[0054] It should be noted that the working process and principle of the solar boost module 300 built based on the SPV1040 solar charging chip U1 in this application embodiment are clear and known to those skilled in the art, and do not constitute a limitation that this application embodiment cannot be implemented or is unclear.
