[0026] The present invention will be further described in detail below in conjunction with specific embodiments, but the implementation methods of the present invention are not limited thereto.

[0027] Example 1

[0028] like Figure 1 As shown, the touch-type electronic cigarette-lighting system in this embodiment includes a control processor MCU, a cigarette-lighting component, a switch amplifier circuit, a trigger switch, and a power supply circuit. Specifically, the control processor MCU in this embodiment is preferably implemented by a JL091D single-chip microcomputer, which is used to realize the power-on and power-off of the cigarette-lighting component by controlling the on and off of the switch amplifier circuit, so that the cigarette-lighting component can obtain a larger current and voltage from the power supply circuit to realize the function of lighting a cigarette or igniting other external combustible items. When connected, the input end of the switch amplifier circuit is connected to the output end of the power supply circuit, the control end of the switch amplifier circuit is connected to the signal control end of the control processor MCU, the output end of the switch amplifier circuit is connected to the input end of the cigarette-lighting component, and the output end of the cigarette-lighting component is grounded, so that an electrical loop is formed between the power supply circuit, the switch amplifier circuit, and the cigarette-lighting component.

[0029] The trigger switch is connected to the control processor MCU and is used to provide the control processor MCU with a trigger signal or a control signal to enable it to work. The trigger switch can be implemented by one mechanical push switch or a touch switch, or by more than two mechanical push switches or touch switches, or even by a combination of multiple mechanical push switches and touch switches.

[0030] To facilitate a more convenient description and understanding of the present invention, the control processor MCU described in this embodiment is illustrated using the JL091D single-chip microcomputer as an example. Other single-chip microcomputers or control chips with similar pins or functions can be used as the control processor MCU. For example, the control processor MCU can also use an FM7011H single-chip microcomputer, H091D or S091D integrated chip, etc. There is no special fixed limitation in this embodiment.

[0031] According to actual needs, in order to conveniently display the working status of the entire circuit and / or put the control processor MCU in a standby state, the utility model can also be specially provided with a mechanical push switch to provide a working status prompt, that is, as long as the mechanical push switch is turned on, the utility model can prompt that it has entered the standby state by means of light, etc. Figure 2 and Figure 3As shown, the trigger switch of the utility model is composed of a touch switch S1 and a push switch S2. Among them, the touch switch S1 is a touch-type patch capacitor switch. When connected, the touch switch S1 is connected to the control end (pin 4) of the control processor MCU. One end of the push switch S2 is connected to pin 5 of the control processor MCU, and the other end is grounded. When in use, the touch switch S1 is used to provide a switch control signal to the control processor MCU, and the push switch S2 is used to control the disconnection and conduction of the ground terminal of the internal circuit of the processor MCU, so that the control processor MCU enters a standby state.

[0032] At the same time, in order to facilitate prompting or displaying that the power supply of the utility model has been turned on or the control processor MCU is in a standby state that can be controlled by touch, therefore, this embodiment can also set a working display circuit between the push switch S2 and the power supply circuit. The working display circuit is composed of a light-emitting diode LED2 and a resistor R1. When connected, the P pole of the light-emitting diode LED2 is connected to the positive pole of the power supply circuit through the resistor R1, and its N pole is connected to the connection point between the push switch S2 and the control processor MCU. At this time, the role of the resistor R1 is to limit the current flowing through the light-emitting diode LED2 to prevent the light-emitting diode LED2 from being damaged.

[0033] During specific installation, the push switch S2 can be installed at the upper end of the lighter body, so that the push switch S2 can be pressed by opening and closing the cover of the lighter, thereby controlling the power supply state of the power supply circuit and the standby state of the control processor MCU. Similarly, the push switch S2 can be set at any other position of the lighter body, as long as the user can directly press the switch S2 to achieve the above functions.

[0034] The power supply circuit is connected to the control processor MCU and the switch amplifier circuit respectively to ensure that the power supply circuit can provide the operating voltage and current for the control processor MCU. The power supply circuit in this embodiment is preferably implemented by a conventional rechargeable lithium-ion rechargeable battery. When connected, the positive terminal of the lithium-ion rechargeable battery is connected to the power input pin of the control chip MCU. In order to facilitate charging the lithium-ion rechargeable battery, a USB charging interface is also required in this embodiment as the connection terminal between the rechargeable battery and the external power supply.

[0035] Furthermore, the cigarette lighting component in this embodiment is composed of a resistance heating wire L1. Specifically, one end of the resistance heating wire L1 is connected to the switch amplifier circuit, and the other end is grounded. In order to facilitate the display of the working status of the cigarette lighting component, this embodiment can also be specially provided with a light-emitting diode LED1 for cigarette lighting display. When connected, the P pole of the light-emitting diode LED1 is connected to the connection point between the cigarette lighting component and the switch amplifier circuit, and the other end is grounded. Similarly, in order to prevent the voltage or current of the switch amplifier circuit from being too large to damage the light-emitting diode LED1, a current-limiting resistor can also be connected in series on the circuit of the light-emitting diode LED1.

[0036] In order to ensure the actual operation effect of the utility model, the switch amplifier circuit is preferably implemented by an amplifier circuit composed of field effect tubes, which not only has a switch function, but also has a current and voltage amplification function. According to the needs of actual operation, the switch amplifier circuit can also be directly hidden or built into the control processor MCU to achieve the purpose of simplifying the circuit.

[0037] like Figure 2 As shown, the switch amplifier circuit is composed of a field effect tube Q1 and a resistor R2. Specifically, the field effect tube Q1 is preferably implemented by a SI2301 field effect tube in this embodiment, and other field effect tubes with the same pins or functions can be used as the field effect tube Q1 in the utility model. When connected, the control end (gate) of the field effect tube Q1 is connected to the No. 6 pin of the control processor MCU, the output end (drain) of the field effect tube Q1 is connected to the input end of the resistance heating wire L1, and the input end (source) of the field effect tube Q1 is connected to the positive pole of the power supply circuit. Resistor R2 is connected in series between the control end (gate) and the input end (source) of the field effect tube Q1 to ensure that when the touch switch S1 is not touched, the field effect tube Q1 is in a cut-off state.

[0038] The working principle of this embodiment is: by controlling the pressing switch S2 (opening the cover of the electronic lighter), the control processor MCU is powered and the light-emitting diode LED2 is lit. At this time, by touching the touch switch S1, the control processor MCU obtains the touch pulse signal, which makes the internal circuits of the 6th and 5th pins of the control processor MCU conductive, and the gate of the field effect tube Q1 is in a low level state. At this time, the field effect tube Q1 is in a conductive amplification state. The current provided by the power supply circuit passes through the field effect tube Q1 and then through the resistance heating wire L1, so that the resistance heating wire L1 heats up to realize the ignition function, and the light-emitting diode LED1 is lit. When the cigarette is lit or ignited, the touch switch S1 is touched again, and the control processor MCU obtains the touch pulse signal again, and the internal circuits of the 6th and 5th pins of the control processor MCU are disconnected, and the gate of the field effect tube Q1 is in a high level state, and the field effect tube Q1 is cut off. When the switch S2 is pressed again (closing the cover of the electronic lighter), the control processor MCU is no longer grounded and is in a power-off state, the light-emitting diode LED2 is turned off, and the light-emitting diode LED1 is turned off.

[0039] Example 2

[0040] The only difference between this embodiment and the first embodiment is that the switch amplifier circuit is not implemented by a field effect transistor, but is implemented by an amplifier circuit composed of a transistor and its bias resistor.

[0041] like Figure 4 As shown, the switch amplifier circuit is composed of a transistor Q2, a bias resistor R3 and a bias resistor R4. When connected, the control end (base) of the transistor Q2 is connected to the control processor MCU (pin 6) through the bias resistor R3, its input end (collector) is connected to the positive electrode of the power supply circuit, and its output end (emitter) is connected to the input end of the resistance heating wire L1. One end of the bias resistor R4 is connected to the output end (emitter) of the transistor Q2, and the other end is grounded.

[0042] In the specific implementation, the transistor Q2 is preferably implemented by a 2N6277 transistor in this embodiment. To ensure the normal operation of the transistor Q2, the resistance of the bias resistor R4 is greater than the resistance of the bias resistor R3. For example, the resistance of the bias resistor R4 in this embodiment is 100K, and the resistance of the bias resistor R3 is 10K. Similarly, the resistance of the bias resistor can be reset according to actual needs, as long as the heating wire L1 can be heated.

[0043] When the transistor Q2 is used as a switching amplifier circuit, the current output pin of the control processor MCU (ie, the control pin connected to the base of the transistor Q2) needs to output current or a high level so that the transistor Q2 can be turned on and off normally.

[0044] The working principle of this embodiment is: by controlling the pressing switch S2 (opening the cover of the electronic lighter), the control processor MCU is powered and the light-emitting diode LED2 is lit. At this time, by touching the touch switch S1, the control processor MCU obtains the touch pulse signal, and the No. 6 pin of the control processor MCU outputs current or high level, and the transistor Q2 is in the on-amplification state. The current provided by the power supply circuit passes through the transistor Q2 and then passes through the resistor heating wire L1, so that the resistor heating wire L1 heats up to realize the ignition function, and the light-emitting diode LED1 is lit. When the cigarette is lit or ignited, the touch switch S1 is touched again, and the control processor MCU obtains the touch pulse signal again, and the No. 6 pin of the control processor MCU stops outputting current or high level, and the transistor Q2 is cut off. When the switch S2 is pressed again (closing the cover of the electronic lighter), the control processor MCU is no longer grounded, and it is in a power-off state, and the light-emitting diode LED2 is extinguished, and the light-emitting diode LED1 is extinguished.

[0045] Example 3

[0046] The difference between this embodiment and embodiment 1 is that the cigarette lighting component of this embodiment is an arc generator. Figure 3 As shown, one end of the arc generator is connected to the output end of the switch circuit amplifier circuit as the input end of the cigarette lighter component, and the other end is grounded as the output end of the cigarette lighter component. The arc generator is composed of a micro transformer T and an arc pair, and the arc pair is the lead pin with a leather led out of the secondary coil of the micro transformer T.

[0047] Specifically, the input end of the primary coil of the micro-transformer T is the input end of the cigarette lighter component, the output end of the primary coil is the output end of the cigarette lighter component, the input end of the cigarette lighter component is connected to the output end of the switch amplifier circuit, the output end of the cigarette lighter component is grounded, and the arc pair is connected to the secondary coil of the micro-transformer T. According to actual needs, as one of the preferred methods, multiple pairs of arc pairs can be set on the secondary coil of a micro-transformer T. Similarly, as a second preferred method, this embodiment can also be provided with multiple micro-transformers T and multiple pairs of arc pairs, and the number of the micro-transformers T must correspond to the number of arc pairs.

[0048] When connecting, no matter one or more micro-transformers T are used, the input ends of the primary coils of all micro-transformers T need to be connected to the output ends of the field effect transistor Q1, and the output ends of the primary coils of the micro-transformers T are grounded, so that an electrical circuit is formed between the power supply battery, the field effect transistor Q1 and the micro-transformer T.

[0049] The working principle of this embodiment is: by controlling the pressing switch S2 (opening the cover of the electronic lighter), the control processor MCU is powered and the light-emitting diode LED2 is lit. At this time, by touching the touch switch S1, the control processor MCU obtains the touch pulse signal, which makes the internal circuits of pins 6 and 5 of the control processor MCU conductive, and the gate of the field effect transistor Q1 is in a low level state. At this time, the field effect transistor Q1 is in a conductive amplification state. The current provided by the power supply circuit is sequentially connected to the ground through the field effect transistor Q1 and the primary coil of the micro transformer T, and the arc pair coupled with the primary coil of the micro transformer T generates a high-voltage arc after coupling transformation, realizing the ignition or cigarette lighting function, and the light-emitting diode LED1 is lit. After lighting a cigarette or igniting the fire, if the touch switch S1 is touched again, the control processor MCU will receive the touch pulse signal again, and the internal circuits of the 6th and 5th pins of the control processor MCU will be disconnected, the gate of the field effect transistor Q1 will be in a high level state, and the field effect transistor Q1 will be cut off. At this time, there is no current and voltage passing through the primary coil of the WeChat transformer T, and the arc pair will not generate an arc. When the switch S2 is pressed again (closing the cover of the electronic lighter), the control processor MCU is no longer grounded, and it is in a power-off state, and the light-emitting diode LED2 is off, and the light-emitting diode LED1 is off.

[0050] Example 4

[0051] like Figure 5 As shown, the difference between this embodiment and embodiment 1 is that a charging circuit connected to the control processor MCU and the power supply circuit is also specially provided in this embodiment. The charging circuit in this embodiment is a unidirectional charging circuit, and the unidirectional charging circuit is preferably implemented by a unidirectional charging circuit composed of an LTC4054 integrated chip U1. Similarly, this embodiment can also be implemented by other types of chips with the same functions as the LTC4054 integrated chip, such as: BL4054, LP4054, TP4054 and other integrated chips.

[0052] In this embodiment, the VCC pin of the integrated chip U1 is grounded through the capacitor C1 and connected to the USB interface, the CHRG pin is connected to a charging indication circuit, the BAT pin is connected to the positive electrode of the lithium-ion rechargeable battery, and the PROG pin is connected to a resistor R5. One end of the resistor R5 is connected to the PROG pin, and the other end is grounded.

[0053] The charging indication circuit is composed of a resistor R6 and a light emitting diode LED3. Specifically, one end of the light emitting diode LED3 is connected to the CHRG pin of the integrated chip U1 through the resistor R6, and the other end is connected to the positive electrode (VCC) of the rechargeable battery.

[0054] Example 5

[0055] like Figure 6 As shown, this embodiment adds a bidirectional charging circuit based on the circuits of embodiments 1 to 3. The so-called bidirectional charging circuit means that this embodiment can charge the power supply circuit of the utility model through an external power supply device, and at the same time, it can also charge other external electrical devices through the power supply circuit of the utility model.

[0056] That is, the bidirectional charging circuit in this embodiment is formed by the TP4333 integrated chip U2, the USB interface, the TYPE-C interface and the charging switch circuit. Similarly, the bidirectional charging circuit described in this embodiment can also be implemented by other types of chips with the same functions as the TP4333 integrated chip U2, such as: SM5401, TP4213, MAX8731, etc.

[0057] In order to ensure the actual operation effect of the utility model, the charging switch circuit is composed of a field effect tube Q3, and the field effect tube Q3 is preferably implemented by an AO3401 field effect tube. Of course, other types of field effect tubes can also be used to replace it according to actual needs.

[0058] The specific structure of the bidirectional charging circuit is as follows: Figure 6 As shown, inductor L2, capacitor C2, capacitor C3, capacitor C4 and capacitor C5 are the expansion circuit of TP4333 integrated chip U2. When connected, the output end (drain) of field effect tube Q3 is connected to the positive electrode of lithium-ion rechargeable battery, and its input end (source) is connected to pin 2 (BAT end) of integrated chip U2. Inductor L2 is connected in series between pin 3 (SW end) of integrated chip U2 and input end (source) of field effect tube Q3. One end of capacitor C2 and one end of capacitor C5 are respectively connected to pin 1 (OUT end) of integrated chip U2, and the other end of capacitor C2 and the other end of capacitor C5 are both grounded. One end of capacitor C3 is connected to the input end (source) of field effect tube Q3, and the other end is grounded. One end of capacitor C4 is connected to pin 6 (VDD end) of integrated chip U2, and the other end is grounded. The No. 1 pin (OUT terminal) of the integrated chip U2 is connected to the USB interface, and the No. 6 pin (VDD terminal) of the integrated chip U2 is connected to the TYPE-C interface. The No. 4 pin (GND terminal) of the integrated chip U2 is grounded.

[0059] During implementation, when the lithium-ion rechargeable battery of the utility model needs to be charged, the TYPE-C interface can be connected to the external power supply through the data line. At this time, the external power supply is connected to the positive electrode of the lithium-ion rechargeable battery through the TYPE-C interface, the integrated chip U2 and the field effect transistor Q3 in sequence to charge the lithium-ion rechargeable battery. When the utility model needs to be used to reversely charge an external power-consuming device, it is only necessary to plug the external power-consuming device into the USB interface. At this time, the current of the lithium-ion rechargeable battery can flow to the external power-consuming device through the field effect transistor Q3, the integrated chip U2 and the USB interface in sequence to charge the external power-consuming device.

[0060] As described above, the utility model can be well implemented.
