As shown in FIG. 3, it is a schematic circuit diagram of the electronic cigarette in FIG. In this embodiment, the touch sensing switch 101 is preferably capacitive sensing, that is, the The touch sensing switch 101 is a capacitor C that connects the conductive surface of the electronic cigarette, and the sensing signal processing module 102 is preferably implemented in the present embodiment as a T T P224 chip. Specifically, one end of the capacitor C is connected to the electronic cigarette The conductive surface, the other end of the capacitor C is connected to the '1' pin of the inductive signal processing module 102. The pin is an input pin, and the sensing signal is received, and the signal processing module 102 is '10'.

2 and FIG. 3, the working principle of the first preferred embodiment of the electronic cigarette of the present invention will be described in detail as follows: when the user touches the hand Or when the oral contact with the touch-sensitive area corresponding to the conductive surface of the electronic cigarette when smoking, the value of the sensing capacitor C changes, that is, the sensing signal is generated, and the sensing signal is transmitted to the first part of the sensing signal processing module. 1 ' pin, the input port, the sensing signal processing module processes the sensing signal after receiving the sensing signal, and at the '16' The pin outputs a low level signal (ie, control signal) to the button switch K1; at the same time, the button switch K1 is pressed, and the low level signal outputted by the sensing signal processing module is transmitted to the input of the control module via the button switch. Pin, this pin is active low, that is, after the input pin receives a low level signal, the control module is at the second output. The pin outputs voltage to the electric heating wire in the atomizer, and the heating wire is a nebulizer heating device, which is used for heating the soot oil to make the atomizing component emit smoke, and the electronic cigarette works normally.

In the above process, if the user does not use the electronic cigarette, it will not touch the conductive surface of the electronic cigarette. At this time, the sensing signal processing module is '1' The pin does not receive the sensing signal, and its '16' pin level is high. At this time, even if the button switch is pressed, the input pin level of the control module is high, and the pin is high. for The low level is valid, so the control module cannot be triggered, that is, the output pin does not output voltage to supply power to the heating wire, and the electronic cigarette does not work. Therefore, the electronic cigarette needs to work normally, and two conditions must be met: the user Contact with the conductive surface of the electronic cigarette And press the button switch, only the electric heating wire can satisfy the two conditions to heat, so as to heat the smoke oil to make the atomizer emit smoke, and the electronic cigarette works normally. In the life, it is easy to squeezing or colliding the electronic cigarette due to the frequent eruption of the electronic cigarette. It is easy to cause the key switch to be triggered by mistake. By using the electronic cigarette provided by the embodiment, even if the button switch is triggered by mistake, as long as the user Without using electronic cigarettes, it will not When the battery rod is touched, the control module will not output voltage to supply power to the heating wire, and the electronic cigarette will not work normally, and there is no safety hazard.

As shown in FIG. 5, it is a schematic structural view of an electronic cigarette according to the present invention, and the electronic cigarette body includes an atomizer 1 and a battery rod 2, The atomizer 1 includes a heating wire 30. Referring to Figures 5 and 6, In this embodiment, the touch switch unit 10 includes a resistor R2, a resistor R3, a resistor R4, and a switch transistor Q1. In this embodiment, the switch transistor Q1 is preferably an NPN transistor, and the positive terminal B+ of the battery 40 is connected to the battery pole. of Conductive surface, one end of the resistor R4 is connected to the conductive surface of the battery rod On the top metal cap J1 of the upper button switch K1, the other end of the resistor R4 is connected to the base of the switch tube Q1, and one end of the resistor R3 and one end of the resistor R2 are connected to the positive terminal B+ of the battery, and the other end of the resistor R3 Connected to the base of the switch Q1, the other end of the resistor R2 is connected to the collector of the switch Q1 and one end of the push switch K1, and the emitter of the switch Q1 is grounded. In addition, the other end of the push button switch K1 is connected to the control module 20, and the control module 20 is connected to the heating wire 30. In the present embodiment, the connection relationship between the key switch K1, the control module 20, the heating wire 30, and some components such as light-emitting diodes is the same as that of FIG. 4, and details are not described herein again.

See Figure 5 and Figure 6 The working principle of the second preferred embodiment of the electronic cigarette of the present invention is as follows: when the user holds the battery rod (the touch area of the hand covers the battery rod conductive surface connecting the positive terminal B+ of the battery) And the metal cap of the top of the button switch, due to the conductive surface of the battery rod Connected to the positive terminal B+ of the battery, at which time the battery voltage is transmitted through the skin to the top metal cap J1 of the push button switch (it is understandable that the top metal cap of the push button switch is placed on the conductive surface of the battery rod) Therefore, the voltage on the top metal cap J1 of the push button switch is the battery voltage, which is applied to the base of the transistor Q1 via the resistor R4. At this time, the base level of the transistor Q1 is at a high level, and the emitter of the transistor Q1 is grounded. At this time, the voltage between the base and the emitter of the transistor Q1 is greater than the turn-on voltage, the transistor Q1 is in a saturated conduction state, and the collector and the emitter of the transistor Q1 are directly connected, so the collector level of the transistor Q1 is a low level. .

At the same time, press the button switch K1 to control the input pin level of the module 20 (the '4' pin in the figure) Low level (active low), at this time, the output pin of control module 20 (the '8' pin in the figure) The output voltage is supplied to the heating wire 30 to heat the smoke oil to generate smoke, and the electronic cigarette works normally.

In the above process, if the user does not need to use the electronic cigarette, the electronic cigarette is separated by a side, the user does not intentionally touch or hold the conductive surface of the battery rod. At this time, the battery voltage will not be transmitted to the top metal cap J1 through the positive terminal B+, J1 is suspended, the base level of the transistor Q1 is low level, which is insufficient to conduct, and the collector of the transistor Q1 passes through the resistor R2 and The positive terminal B+ of the battery is connected, so the collector level of the transistor Q1 is at a high level. At this time, even if the button switch K1 is pressed, the potential of the button switch K1 is the same, and the input pin of the control module 20 is also high. And the pin is active low for the input, at this time the control module 20 Output The pin does not output a voltage to the heating wire 30, that is, the heating wire 30 cannot be controlled to generate heat, that is, the electronic cigarette does not work. Therefore, this embodiment is also very good as long as the user does not need to use the electronic cigarette, and will not hold the battery rod, even if the button switch K1 is triggered by mistake, the heating wire will not heat, the electronic cigarette does not work, and thus does not There are security risks.

Figure 7 Shown is a schematic circuit diagram of a third preferred embodiment of the electronic cigarette of the present invention. 2, in this embodiment, the touch switch unit 10 includes an operational amplifier U1 and a resistor R5, and an inverting input terminal of the operational amplifier U1 is connected to the battery rod. On the top metal cap of the push button switch on the conductive surface, the positive terminal B+ of the battery 40 is connected to the conductive surface of the battery rod The non-inverting input terminal of the operational amplifier U1 is connected to the negative terminal B- of the battery, and the output end of the operational amplifier U1 is respectively connected with one end of the resistor R5 and one end of the key switch K1, and the positive terminal B+ of the other end of the resistor R5 is connected. The other end of the button switch K1 is connected to the control module 20. In the present embodiment, the connection relationship between the key switch K1, the control module 20, the heating wire 30, and some components such as light-emitting diodes is the same as that of FIG. 4, and details are not described herein again.

See Figure 5 and Figure 7 The working principle of the third preferred embodiment of the present invention will now be described in detail as follows: when the user holds the battery rod (the finger touch area covers the conductive surface of the battery rod connecting the positive terminal B+ of the battery) And the conductive metal surface of the battery rod when the button top metal cap) Connected to the positive terminal B+ of the battery. At this time, the battery voltage is transmitted to the top metal cap J1 of the button switch through the skin. Therefore, the voltage on the top metal cap J1 of the button switch is the battery voltage, because it has the inverse of the operational amplifier U1. The phase input terminal, and the non-inverting input terminal of the operational amplifier U1 is grounded, that is, the voltage of the inverting input terminal of the operational amplifier is higher than the voltage of the non-inverting input terminal, so the output terminal of the operational amplifier outputs a low level.

Simultaneously pressing the button switch K1, the input pin of the control module 20 is low level (the pin is active low), and the output of the control module 20 is output at this time. The pin will output a voltage to supply power to the heating wire 30, heat the smoke oil to generate smoke, and the electronic cigarette can work normally.

In the above process, when the user does not use the electronic cigarette, the electronic cigarette is separated by a side, the user does not intentionally touch or hold the battery rod, and the battery voltage is not transmitted to the top metal cap J1 through the positive terminal B+. J1 is left floating, and the inverting input terminal of the operational amplifier U1 is at a low level, because the output terminal of the operational amplifier U1 is connected to the positive terminal B+ of the battery via the resistor R5, that is, the output level of the operational amplifier is high. At this time, even if the button switch K1 is pressed, the potential of the button switch K1 is the same, and the input pin of the control module 20 is also high level (the pin is active low), so the control module 20 does not output voltage to the electric heater. The wire 30 is powered, that is, the heating wire 30 does not generate heat, and the electronic cigarette does not work. Therefore, this embodiment also realizes that even if the button switch K1 is erroneously triggered, as long as the user does not touch the metal casing of the battery rod, the heating wire will not generate heat, and there is no safety hazard.
