The present invention is further described in detail below with reference to the accompanying drawings and the embodiments.
Specifically, the power supply identifying circuit includes: a first control chip 111, a first switch M1, a second switch M2, and a first resistor R1. The first control chip 111 includes a first drive end P1, a second drive end P2, and a feedback end ADC. The first switch M1 includes a control end, a first channel end, and a second channel end. The control end of the first switch M1 is connected to the first drive end P1 of the first control chip 111 to receive a first drive signal, the first channel end of the first switch M1 is connected to a power supply voltage VCC, and the second channel end of the first switch M1 is connected to the power supply voltage connection end n1 of the battery rod 11. The second switch M2 includes a control end, a first channel end, and a second channel end. The control end of the second switch M2 is connected to the second drive end P2 to receive a second drive signal, the first channel end of the second switch M2 is connected to the power supply voltage VCC, and the second channel end of the second switch M2 is connected to the power supply voltage connection end n1 of the battery rod 11 through the first resistor R1. Specifically, the first resistor R1 includes a first channel end and a second channel end, the first channel end of the first resistor R1 is connected to the power supply voltage connection end n1 of the battery rod 11, and the second channel end of the first resistor R1 is connected to the second channel end of the second switch M2. The feedback end ADC of the first control chip 111 is connected to the power supply voltage connection end n1 of the battery rod 11, and the ground voltage connection end n2 of the battery rod 11 is connected to a ground voltage GND.
In an embodiment, if the vaporizer inserted into the battery rod 11 does not include an identification circuit, the second drive end P2 of the first control chip 111 outputs the second drive signal, and the second drive signal is used to turn on the second switch M2. The first resistor R1 and a heating element in the vaporizer are connected in series between the power supply voltage VCC and the ground voltage GND. The feedback end ADC receives a feedback voltage on the power supply voltage connection end n1 of the battery rod 11 between the first resistor R1 and the heating element to determine performance parameters of a heating wire. The first control chip 111 adjusts the first drive signal outputted by the first drive end P1 according to the feedback voltage, so that the battery rod 11 uses the corresponding power to drive the heating element in the vaporizer, and further heats a vaporization substrate in the vaporizer.
In the embodiments of the present invention, to realize mutual identification of the battery rod 11 and the vaporizer, the vaporizer inserted into the battery rod 11 includes an identification circuit. Specifically, when the vaporizer inserted into the battery rod 11 includes the identification circuit, the first control chip 111 controls the first switch M1 by using the first drive signal to supply power to the vaporizer, and controls the second switch M2 by using the second drive signal to communicate with the identification circuit of the vaporizer, to obtain the identification information of the vaporizer, and adjust the first drive signal according to the identification information fed back to use the corresponding power to drive the vaporizer. That is, when the vaporizer inserted into the battery rod 11 includes the identification circuit, the first switch M1 and the second switch M2 further have the function of obtaining the identification information of the vaporizer in addition to the function of driving the heating element to heat.
Specifically, with reference to
Specifically, when the vaporizer with the identification circuit is inserted into the battery rod 11, the battery rod 11 supplies power to the vaporizer, that is, the power-on period L1 is performed. During the power-on period L1, the first drive end P1 of the first control chip 111 outputs the first drive signal. Specifically, the first drive signal drives the first switch M1 with a pulse signal formed by a first logic level of a first duration and a second logic level of a second duration, so that the vaporizer is powered on to work. Specifically, in a specific embodiment, the first logic level is a high-level signal, the second logic level is a low-level signal, the first logic level of the first duration is a high-level signal of 50 us, and the second logic level of the second duration is a low-level signal of 500 us. Specifically, the first drive end P1 of the first control chip 111 of the battery rod 11 applies a pulse signal formed by the high-level signal of 50 us and the low-level signal of 500 us to the first switch M1, to drive the first switch M1 to be turned on. After the first switch M1 is turned on, the power supply voltage VCC charges the vaporizer through the first switch M1, thereby providing electric energy for the vaporizer. In an embodiment, it generally takes 6 ms to power on the vaporizer. Therefore, before the vaporizer is woken up, the first drive end P1 outputs a plurality of pulse signals
During the data sending period L2, the first drive signal drives the first switch M1 by using a pulse signal formed by a first logic level of an eighth duration, and a second logic level of a ninth duration or a second logic level of a tenth duration, to generate a sending voltage of the ninth duration or a sending voltage of the tenth duration at the power supply voltage connection end n1 of the battery rod 11 as a corresponding sending digital signal, to form sending data to be sent to the vaporizer. Specifically, the first logic level of the eighth duration is a high-level signal of 200 us, the second logic level of the ninth duration is a low-level signal of 500 us, and the second logic level of the tenth duration is a low-level signal of 250 us. In a specific embodiment, the first drive signal may drive the first switch M1 by using a pulse signal formed by the high-level signal of 200 us and the low-level signal of 500 us, to generate a sending voltage of the low-level signal of 500 us at the power supply voltage connection end n1 of the battery rod 11, and send the sending voltage to the vaporizer. Alternatively, the first drive signal may alternatively drive the first switch M1 by using a pulse signal formed by the high-level signal of 200 us and the low-level signal of 250 us, to generate a sending voltage of the low-level signal of 250 us at the power supply voltage connection end n1 of the battery rod 11, and send the sending voltage to the vaporizer. Specifically, when the sending voltage is a low-level signal of 500 us, data “1” can be sent; and when the sending voltage is a low-level signal of 250 us, data “0” can be sent.
During the response waiting period L3, the first drive signal drives the first switch M1 by using a pulse signal formed by a first logic level of an eleventh duration and a second logic level of a twelfth duration; and when the first drive signal is at the second logic level, the second drive signal drives the second switch M2 by using a pulse signal formed by a first logic level of a thirteenth duration and a second logic level of a fourteenth duration. When the identification circuit of the vaporizer sends a response to perform a discharge operation on the power supply voltage connection end n1 of the battery rod 11, a waiting voltage of the thirteenth duration of the power supply voltage connection end n1 of the battery rod 11 is switched to a response voltage of a fifteenth duration, which is then fed back to the feedback end of the first control chip 111, thereby informing the first control chip 111 to wait to receive the identification information fed back. Specifically, the first logic level of the eleventh duration may be a high-level signal of 200 us, and the second logic level of the twelfth duration may be a low-level signal of 700 us; and the first drive signal drives the first switch M1 by using a pulse signal formed by the high-level signal of 200 us and the low-level signal of 700 us. The first logic level of the thirteenth duration is a high-level signal of 300 us, and the second logic of the fourteenth duration is a low-level signal of 400 us. Specifically, when the first drive signal is at the low-level signal of 700 us, the second drive signal drives the second switch M2 by using a pulse signal formed by the high-level signal of 300 us and the low-level signal of 400 us. Specifically, when the vaporizer receives the sending voltage, the identification circuit of the vaporizer sends a response to perform a discharge operation on the power supply voltage connection end n1 of the battery rod 11. In this case, the second high-level signal of 300 us of the power supply voltage connection end n1 of the battery rod 11 is switched to a second high-level signal of 150 us to form a response voltage, which is then fed back to the feedback end ADC of the first control chip 111, thereby informing the first control chip 111 to wait to receive the identification information fed back.
During the feedback data receiving period L4, the first drive signal drives the first switch M1 by using a pulse signal formed by a first logic level of a third duration and a second logic level of a fourth duration, to supply power to the vaporizer. When the first drive signal is at the second logic level, the second drive signal drives the second switch M2 by using a pulse signal formed by a first logic level of a fifth duration and a second logic level of a sixth duration. When the second drive signal is at the first logic level, the identification circuit of the vaporizer determines to perform the discharge operation on the power supply voltage connection end n1 of the battery rod 11 according to the identification information, to generate a feedback voltage of the fifth duration or a feedback voltage of a seventh duration at the power supply voltage connection end n1 of the battery rod 11 as a corresponding feedback digital signal, to form identification information to be fed back to the feedback end ADC of the first control chip 111. Specifically, the first logic level of the third duration is a high-level signal of 200 us, and the second logic level of the fourth duration is a low-level signal of 700 us. The first drive signal drives the first switch M1 by using the high-level signal of 200 us and the low-level signal of 700 us to supply power to the vaporizer. The first logic level of the fifth duration is a high-level signal of 300 us, and the second logic level of the sixth duration is a low-level signal of 400 us. In a specific embodiment, when the first drive signal is at the low-level signal of 700 us, the second drive signal drives the second switch M2 by using the pulse signal formed by the high-level signal of 300 us and the low-level signal of 400 us. In addition, when the second drive signal is at the high-level signal of 300 us, the identification circuit of the vaporizer performs the discharge operation on the power supply voltage connection end n1 of the battery rod 11, to generate a high-level signal of 300 us or a high-level signal of 150 us at the power supply voltage connection end n1 of the battery rod 11 as a corresponding feedback digital signal, to form identification information to be fed back to the feedback end ADC of the first control chip 111. The high-level signal of 150 us is the feedback voltage of the seventh duration. Specifically, in an embodiment, if the feedback voltage received by the feedback end ADC of the first control chip 111 is the high-level signal of 300 us, it indicates that the data “1” returned by the vaporizer is received. If the feedback voltage received by the feedback end ADC of the first control chip 111 is the high-level signal of 150 us, it indicates that the data “0” returned by the vaporizer is received. It may be understood that, as shown in
In a specific embodiment, the first switch M1 and the second switch M2 may be NMOS transistors and PMOS transistors, or may be PNP transistors and NPN transistors. The first control chip 111 may be a general-purpose programmable control chip, or a customized non-programmable control chip, which is not specifically limited.
The battery rod provided in the present invention includes the power supply identifying circuit. When the vaporizer is inserted into the battery rod, the power supply identifying circuit receives the identification information fed back by the vaporizer, and uses, according to the identification information fed back, the corresponding power to drive the vaporizer, so that the problem of poor user experience caused by mixing a battery rod and a vaporizer of different models can be avoided, and the vaporizer can be driven with the power matching the vaporizer. Further, a vaporization substrate in the vaporizer can still obtain the expected effect after vaporization, which improves the user experience.
The vaporizer 12 further includes an identification circuit. The identification circuit is connected in parallel with the heating element H and connected to the power supply voltage connection end m1 and the ground voltage connection end m2 of the vaporizer 12, and is configured to communicate with the power supply identifying circuit of the battery rod 11, to feed back identification information to the battery rod 11, for the battery rod 11 to use, according to the identification information fed back, a corresponding power to drive the heating element H of the vaporizer 12, thereby vaporizing a vaporization substrate in the vaporizer 12.
In a specific embodiment, the vaporizer 12 further includes a liquid storage chamber, and the heating element H may be placed in the liquid storage chamber. The liquid storage chamber stores a vaporization substrate, for example, e-liquid. When the battery rod 11 uses the corresponding power to drive the heating element H, the heating element H generates heat and vaporizes the e-liquid stored in the liquid storage chamber.
Specifically, the identification circuit includes: a second control chip 121, a switch module Q3, and a storage capacitor C1. The second control chip 121 includes a power supply end VCC, a signal acquisition end P4, and a drive end P3. The storage capacitor C1 includes the first end and the second end. The first end of the storage capacitor C1 is connected to the power supply voltage connection end m1 of the vaporizer 12, the second end of the storage capacitor C1 is connected to the ground voltage connection end m2 of the vaporizer 12, and the first end of the storage capacitor C1 is connected to the power supply end of the second control chip 121. The switch module Q3 includes a first channel end, a second channel end, and a control end, where the control end of the switch module Q3 is connected to the drive end P3 of the second control chip 121, the first channel end of the switch module Q3 is connected to the power supply voltage connection end m1 of the vaporizer 12, and the second channel end of the switch module Q3 is connected to the ground voltage connection end m2 of the vaporizer 12. The signal acquisition end P4 of the second control chip 121 is connected to the power supply voltage connection end m1 of the vaporizer 12.
In an embodiment, when the vaporizer 12 is inserted into the battery rod 11, referring to
When the battery rod 11 operates in the data sending period L2, the signal acquisition end P4 of the second control chip 121 acquires a sending voltage of a ninth duration or a sending voltage of a tenth duration at the power supply voltage connection end m1 of the vaporizer 12 as a correspondingly sending digital signal, thereby acquiring and generating corresponding sending data. Specifically, when the battery rod 11 operates in the data sending period L2, a low-level signal of 500 us or a sending voltage of a low-level signal of 250 us is generated at the power supply voltage connection end n1 of the battery rod 11. Specifically, if the power supply voltage connection end n1 of the battery rod 11 generates the low-level signal of 500 us, it indicates that the battery rod 11 sends data “1”; and if the power supply voltage connection end n1 of the battery rod 11 generates the low-level signal of 250 us, it indicates that the battery rod 11 sends data “0”.
In this case, if the signal acquisition end P4 of the second control chip 121 acquires the low-level signal with the sending voltage of 500 us at the power supply voltage connection end m1 of the vaporizer 12, it indicates that the vaporizer 12 receives the data “1”; and if the signal acquisition end P4 of the second control chip 121 acquires the low-level signal with the sending voltage of 250 us at the power supply voltage connection end m1 of the vaporizer 12, it indicates that the vaporizer 12 receives the data “0”.
Specifically, in an embodiment, the second control chip 121 further includes a timer 122, and the timer 122 cooperates with the signal acquisition end P4 to identify the sending voltage of the ninth duration or the sending voltage of the tenth duration at the power supply voltage connection end m1 of the vaporizer 12. Specifically, when the signal acquisition end of the second control chip 121 of the vaporizer 12 receives a low-level signal, the timer 122 is started to work. If the timer 122 displays a time of 500 us, it indicates that the vaporizer 12 receives the data “1”; and if the timer 122 displays a time of 250 us, it indicates that the vaporizer 12 receives the data “0”. Alternatively, in another embodiment, the second control chip further includes an analog-to-digital conversion module 123. For details, reference may be made to
When the battery rod 11 operates in the response waiting period L3, the second control chip 121 controls the switch module Q3 to perform the discharge operation on the power supply voltage connection end m1 of the vaporizer 12, so that the waiting voltage of the thirteenth duration at the power supply voltage connection end m1 of the vaporizer 12 is switched to the response voltage of the fifteenth duration, and a response signal is generated at the power supply voltage connection end m1 of the vaporizer 12 to notify the first control chip 111 to wait to receive the identification information fed back. Specifically, when the battery rod 11 operates in the response waiting period L3, a second drive signal outputted by the second drive end P2 of the first control chip 111 of the battery rod 11 is a high-level signal of 300 us. If the vaporizer 12 is still in a process of processing data, the drive end P3 of the second control chip 121 of the vaporizer 12 does not output any signal, that is, in a low-level state. In this case, the level of the power supply voltage connection end m1 of the vaporizer 12 continues to be a high-level signal of 300 us. If the vaporizer 12 has received sending data and returns a corresponding voltage, the drive end P3 of the second control chip 121 of the vaporizer 12 outputs a high-level signal of 150 us, so that level of the power supply voltage connection end m1 of the vaporizer 12 is switched from the high-level signal of 300 us to the high-level signal of 150 us. In this case, the feedback end ADC of the first control chip 111 of the battery rod 11 acquires a response voltage of the power supply voltage connection end m1 of the vaporizer 12. If a duration of the response voltage is not 300 us but 150 us, it indicates that the vaporizer has responded. When the battery rod 11 operates in the feedback data receiving period L4, the second control chip 121 controls the switch module Q3 to determine the discharge operation on the power supply voltage connection end m1 of the vaporizer 12, so that the power supply voltage connection end m1 of the vaporizer 12 generates the feedback voltage of the fifth duration or the feedback voltage of the seventh duration as a corresponding feedback digital signal to form the identification information fed back. Specifically, when the battery rod 11 operates in the feedback data receiving period L4, the second drive end P2 of the first control chip 111 of the battery rod 11 applies the high-level signal of 300 us to the second switch M2. If the drive end P3 of the second control chip 121 of the vaporizer 12 outputs a low-level signal, that is, the switch module Q3 is turned off or outputs the data “1”, the voltage of the power supply voltage connection end m1 of the vaporizer 12 in this case continues to be the high-level signal of 300 us; and if the drive end P3 of the second control chip 121 of the vaporizer 12 outputs a high-level signal, that is, the switch module Q3 is turned on or outputs the data “0”, the voltage of the power supply voltage connection end m1 of the vaporizer 12 continues to be the high-level signal of 150 us. In this case, if the feedback end ADC of the first control chip 111 of the battery rod 11 acquires that the voltage of the power supply voltage connection end m1 of the vaporizer 12 continues to be the high-level signal of 300 us, it indicates that the data “1” returned by the vaporizer 12 is received; and if the feedback end ADC of the first control chip 111 of the battery rod 11 acquires that the voltage of the power supply voltage connection end m1 of the vaporizer 12 continues to be the high-level signal of 150 us, the data “0” returned by the vaporizer 12 is received.
It may be understood that the waveforms shown in
The vaporizer provided in the present invention includes an identification circuit. The identification circuit is connected in parallel with the heating element and connected to the power supply voltage connection end m1 and the ground voltage connection end m2 of the vaporizer, and is configured to communicate with the power supply identifying circuit of the battery rod, to feed back identification information to the battery rod. Therefore, the battery rod uses, according to the identification information fed back, the corresponding power to drive the heating element of the vaporizer, so that the problem of poor user experience caused by mixing a battery rod and a vaporizer of different models can be avoided, and the vaporizer can be driven with the power matching the vaporizer. Further, a vaporization substrate in the vaporizer can still obtain the expected effect after vaporization, which improves the user experience.
In this embodiment, a switch module 124, also the switch module Q3 in
In another embodiment, the switch module 124 further includes a second resistor R2, and the second resistor R2 includes the first end and the second end, where the first end of the second resistor R2 is connected to the control ends of the third switch M3 and the fourth switch M4, and the second end of the second resistor R2 is connected to the ground voltage output end GND.
In a specific embodiment, the third switch M3 and the fourth switch M4 are NMOSFETs. In this embodiment, drains of the third switch M3 and the fourth switch M4 are connected to implement the turn-on and turn-off of the circuit. It can prevent the voltage from being clamped to the ground voltage through body diodes of the third switch M3 and the fourth switch M4 when the vaporizer 12 is inserted into the battery rod 11 rightly or reversely.
Specifically, when the battery rod 11 operates in the data sending period L2, if the vaporizer 12 is inserted into the battery rod 11 rightly, that is, the power supply voltage connection end m1 of the vaporizer 12 is connected to the power supply voltage connection end n1 of the battery rod 11 and the ground voltage connection end m2 of the vaporizer 12 is connected to the ground voltage connection end n2 of the battery rod, voltages of the control ends (gates) of the third switch M3 and the fourth switch M4 are at a low level. In this case, both the third switch M3 and the fourth switch M4 are turned off, and the voltage reaches the first channel end (source) of the fourth switch M4 first. Since the fourth switch M4 has a body diode, the voltage may reach a cathode from an anode of the body diode, and reach the third switch M3. However, since the body diode of the third switch M3 is opposite to that of the fourth switch M4, the voltage cannot pass through the third switch M3, so that the switch module 124 can be turned off. If the vaporizer 12 is inserted into the battery rod 11 reversely, that is, the power supply voltage connection end m1 of the vaporizer 12 is connected to the ground voltage connection end n2 of the battery rod 11 and the ground voltage connection end m2 of the vaporizer 12 is connected to the power supply voltage connection end n1 of the battery rod 11, voltages of the control ends (gates) of the third switch M3 and the fourth switch M4 are at a low level. In this case, both the third switch M3 and the fourth switch M4 are turned off, and the voltage reaches the first channel end (source) of the third switch M3 first. Since the third switch M3 has a body diode, the voltage may reach a cathode from an anode of the body diode, and reach the fourth switch M4. However, since the body diode of the third switch M3 is opposite to that of the fourth switch M4, the voltage cannot pass through the fourth switch M4, so that the switch module 124 can be turned off.
Specifically, when the battery rod 11 operates in the feedback data receiving period L4, if the vaporizer 12 is inserted into the battery rod 11 rightly, that is, the power supply voltage connection end m1 of the vaporizer 12 is connected to the power supply voltage connection end n1 of the battery rod 11 and the ground voltage connection end m2 of the vaporizer 12 is connected to the ground voltage connection end n2 of the battery rod, voltages of the control ends (gates) of the third switch M3 and the fourth switch M4 are at a high level. A voltage difference Vgs between the control end (gate) and the first channel end (source) of the third switch M3 is greater than a threshold voltage. In this case, the third switch M3 is turned on first, and the drain of the fourth switch M4 is turned on, and then connected to the ground voltage output end GND. The voltage of the first channel end (source) of the fourth switch M4 is clamped to Vsd by the body diode. When a voltage difference Vgs between the gate and the source of the fourth switch M4 is greater than the threshold voltage, the fourth switch M4 is also turned on, so that the switch module 124 is turned on. If the vaporizer 12 is inserted into the battery rod 11 reversely, that is, the power supply voltage connection end m1 of the vaporizer 12 is connected to the ground voltage connection end n2 of the battery rod 11 and the ground voltage connection end m2 of the vaporizer 12 is connected to the power supply voltage connection end n1 of the battery rod 11, voltages of the control ends (gates) of the third switch M3 and the fourth switch M4 are at a high level. A voltage difference Vgs between the control end (gate) and the first channel end (source) of the fourth switch M4 is greater than the threshold voltage. In this case, the fourth switch M4 is turned on first, and the drain of the third switch M3 is turned on, and then connected to the ground voltage output end GND. The voltage of the first channel end (source) of the third switch M3 is clamped to Vsd by the body diode. When a voltage difference Vgs between the gate and the source of the third switch M3 is greater than the threshold voltage, the third switch M3 is also turned on, so that the switch module 124 is turned on.
Specifically, if only the third switch M3 exists in the switch module 124, when the vaporizer 12 is inserted into the battery rod 11, the third switch M3 can be normally turned off or turned on. However, when the vaporizer is inserted into the battery rod 11 reversely, the body diode of the third switch M3 directly conducts the ground voltage connection end m2 of the vaporizer 12 to the ground. If only the fourth switch M4 exists in the switch module 124, when the vaporizer 12 is inserted into the battery rod 11, the fourth switch M4 can be normally turned off or turned on. However, when the vaporizer is inserted into the battery rod 11 reversely, the body diode of the fourth switch M4 directly conducts the power supply voltage connection end m1 of the vaporizer 12 to the ground. As a result, there is a problem that the body diode is clamped to the ground voltage output end GND, resulting in the failure of the circuit.

Specifically, in an embodiment, the second control chip 121 in the vaporizer 12 further includes a ground voltage output end GND, and the ground voltage output end GND in the rectifying circuit 126 is connected to the ground voltage output end GND of the second control chip 121. Specifically, the power supply voltage output end VCC in the rectifying circuit 126 is connected to the power supply end VCC of the second control chip 121.
Specifically, when the vaporizer 12 is inserted into the battery rod 11 rightly, the power supply voltage connection end m1 of the vaporizer 12 is connected to the power supply voltage connection end n1 of the battery rod 11 and receives the power supply voltage output end VCC; and the ground voltage connection end m2 of the vaporizer 12 is connected to the ground voltage connection end n2 of the battery rod 11 and receives the ground voltage output end GND. In this case, since the ground voltage connection end m2 of the vaporizer 12 is connected to the ground voltage connection end n2 of the battery rod 11, the second control unit 127 controls the fifth switch M5 in the second path to be turned on and the sixth switch M6 to be turned off, and the ground voltage connection end m2 is connected to the ground voltage output end GND through the fifth switch M5. Since the power supply voltage connection end m1 of the vaporizer 12 is connected to the power supply voltage connection end n1 of the battery rod 11, the first control unit 128 controls the seventh switch M7 in the first path to be turned on and the eighth switch M8 to be turned off, and the power supply voltage connection end m1 is connected to the power supply voltage output end VCC through the seventh switch M7.
When the vaporizer 12 is reversely inserted into the battery rod 11, the power supply voltage connection end m1 of the vaporizer 12 is connected to the ground voltage connection end n2 of the battery rod 11 and receives the ground voltage output end GND; and the ground voltage connection end m2 of the vaporizer 12 is connected to the power supply voltage connection end n1 of the battery rod 11 and receives the power supply voltage VDD. In this case, since the ground voltage connection end m2 of the vaporizer 12 is connected to the power supply voltage connection end n1 of the battery rod 11, the second control unit 127 controls the sixth switch M6 in the second path to be turned on and the fifth switch M6 to be turned off, and the ground voltage connection end m2 is connected to the power supply voltage output end VCC through the sixth switch M6. Since the power supply voltage connection end m1 of the vaporizer 12 is connected to the ground voltage connection end n2 of the battery rod 11, the first control unit 128 controls the eighth switch M8 in the first path to be turned on and the seventh switch M7 to be turned off, and the power supply voltage connection end m1 is connected to the ground voltage output end GND through the eighth switch M8.
Specifically, when the vaporizer 12 is inserted into the battery rod 11 rightly, the power supply voltage connection end m1 is connected to a positive voltage, the third capacitor C3 in the second control unit 127 is charged, the fifth switch M5 is turned on, and the sixth switch M6 is turned off. At a moment when the level of the power supply voltage connection end m1 changes from high to low, the third capacitor C3 cannot discharge through the second diode D2, and can only discharge slowly through the third resistor R3. The gates of the sixth switch M6 and the fifth switch M5 are maintained at a high level, the fifth switch M5 is kept in an on state, and the sixth switch M6 is kept in an off state, until the fifth switch M5 is turned off when the gate voltage thereof is lower than the threshold voltage. The second diode D2, the third resistor R3, and the third capacitor C3 are grounded, and thus are always in a low level state. In addition, when the vaporizer 12 is inserted into the battery rod 11 rightly, the level of the power supply voltage connection end m1 is instantaneously high, and the seventh switch M7 in the first path is turned on. The eighth switch M8 is turned off instantaneously. Moreover, at a moment when the level of the power supply voltage connection end m1 changes from high to low, the seventh switch M7 and the eighth switch M8 are turned off simultaneously. In this embodiment, the first control unit 128 and the second control unit 127 can always keep the fifth switch M5 in an on state for a required time (for example, about 30 ms, where the required time is determined by the values of the third resistor R3 and the third capacitor C3) when the vaporizer 12 is inserted rightly. Without the first control unit 128 and the second control unit 127, when the power supply voltage connection end m1 is switched from a high level to a low level, the fifth switch M5, the sixth switch M6, the seventh switch M7, and the eighth switch M8 are turned off simultaneously. As a result, there is a voltage difference between the gate and the source of the third switch M3 and the fourth switch M4 of the switch module 124, and then the third switch M3 and the fourth switch M4 are turned on. Consequently, the communication between the vaporizer 12 and the battery rod 11 is interrupted.
Specifically, when the vaporizer 12 is inserted into the battery rod 11 reversely, the ground voltage connection end m2 is connected to a positive voltage, the second capacitor C2 in the first control unit 128 is charged, the eighth switch M8 is turned on, and the seventh switch M7 is turned off. At a moment when the level of the ground voltage connection end m2 changes from high to low, the second capacitor C2 cannot discharge through the third diode D3, and can only discharge slowly through the fourth resistor R4. The gates of the seventh switch M7 and the eighth switch M8 are maintained at a high level, the eighth switch M8 is kept in an on state, and the seventh switch M7 is kept in an off state, until the eighth switch M8 is turned off when the gate voltage thereof is lower than the threshold voltage. The third diode D3, the fourth resistor R4, and the second capacitor C2 are grounded, and thus are always in a low level state. In addition, when the vaporizer 12 is inserted into the battery rod 11 reversely, the level of the ground voltage connection end m2 is instantaneously high, and the sixth switch M6 in the second path is turned on. The fifth switch M5 is turned off instantaneously. Moreover, at a moment when the level of the ground voltage connection end m2 changes from high to low, the fifth switch M5 and the sixth switch M6 are turned off simultaneously. In this embodiment, the first control unit 128 and the second control unit 127 can always keep the sixth switch M6 in an on state for a required time (for example, about 30 ms, where the required time is determined by the values of the fourth resistor R4 and the second capacitor C2) when the vaporizer 12 is inserted reversely. Without the first control unit 128 and the second control unit 127, when the power supply voltage connection end m1 is switched from a high level to a low level, the fifth switch M5, the sixth switch M6, the seventh switch M7, and the eighth switch M8 are turned off simultaneously. As a result, there is a voltage difference between the gate and the source of the third switch M3 and the fourth switch M4 of the switch module 124, and then the third switch M3 and the fourth switch M4 are turned on. Consequently, the communication between the vaporizer 12 and the battery rod 11 is interrupted.
Specifically, the battery rod 11 in this embodiment includes the battery rod shown in
In the electronic vaporization device shown in this embodiment, the vaporizer 12 is inserted into the battery rod 11, and the battery rod 11 supplies power to the vaporizer 12 and sends data to the vaporizer 12. After receiving the sending data sent by the battery rod 11, the vaporizer 12 feeds back identification information to the battery rod 11, for the battery rod 11 to use, according to the identification information, a corresponding power to drive the vaporizer 12, to avoid the mixing of the battery rod 11 and the vaporizer 12. Specifically, if the battery rod 11 and the vaporizer 12 are mixed, a difference in driving powers causes the odor of smoke or the amount of smoke to be too small or too large. In another example, a difference in resistance values of the heating wire leads to cases such as overcurrent protection and no smoke generation. Through the method of the present invention, the battery rod 11 and the vaporizer 12 can be identified with each other, and the battery rod 11 can use the power matching the vaporizer 12 to drive the vaporizer 12, thereby improving the user experience.
