The user can operate the nebulizer 120 and the power supply device 110 to configure the nebulizer 120 in the operation state and the extraction state in response to a need for suction or a need for replacing the nebulizer 120.
Further in accordance with the alternative implementation shown in fig. 1, the power supply apparatus 110 further comprises: first and second electrical contacts a, b at least partially exposed within the receiving cavity 112; wherein the first electrical contact a and the second electrical contact b are configured to make an electrical connection with the atomizer 120 to supply power to the atomizer 120 when the atomizer 120 is received and accommodated within the receiving chamber 112. In particular, the method comprises the steps of,
when the atomizer 120 is coupled to the power supply unit 110, the first electrical contact a may be connected to a first end of the resistive heating element R2 and the second electrical contact b may be connected to a second end of the resistive heating element R2.
The first electrical contact a may form a connection between the first end of the resistive heating element R2 and the second end of the voltage divider resistor R by connecting to the second end of the voltage divider resistor R. The second electrical contact b is connected to the second electrode of the cell 111, thereby forming a connection between the second end of the resistance heating element R2 and the second electrode.
The atomizer 120 has a liquid substrate stored therein and includes a resistive heating element R2 for heating the atomized liquid substrate; when the atomizer 120 is received and accommodated in the receiving cavity 112, the two ends of the resistance heating element R2 are respectively connected with the first electrical contact a and the second electrical contact b and are conducted, so that electric power can be supplied to heat the battery cell 111.
Further in the alternative embodiment shown in fig. 1, the power supply apparatus 110 further includes:
a circuit 113 for conducting electrical current between the cell 111 and the first and second electrical contacts a, b; at the same time, the circuit 113 is also capable of detecting the resistance value of the resistive heating element R2 of the atomizer 120 incorporated in the power supply unit 110 in the operating state, and of adjusting the power output from the electric core 111 in accordance with the detected resistance value, so that the resistive heating element R2 heats the atomized liquid matrix at a suitable temperature.
Further in alternative implementations, the resistive heating element R2 may be configured as a spiral resistive heating wire, a planar heating sheet, or a coiled resistive heating web, or a printed or printed resistive heating trace, or the like.
In a further more preferred implementation, the circuit 113 may be configured as shown in fig. 2, including:
a switch tube Q1, a first resistor R1, a voltage dividing resistor R and a controller 114.
And a voltage dividing resistor R having a first end connected to the first electrode through a switching tube Q1, wherein when the atomizer 120 is coupled to the power supply unit 110, the resistive heating element R2 has a first end connected to a second end of the voltage dividing resistor R and a second end connected to the second electrode.
The first resistor R1 may have a first terminal connected to the first electrode and a second terminal connected to the control terminal of the switching transistor Q1.
The voltage dividing resistor R is used to make series conduction with the resistive heating element R2 when both ends of the resistive heating element R2 are connected to the first electrical contact a and the second electrical contact b to make conduction. In the embodiment shown in fig. 2, the first end of the voltage dividing resistor R is connected to the first electrical contact a, and the second electrical contact b is grounded, so that the resistance value of the resistive heating element R2 can be calculated by sampling the voltage value at the point between the voltage dividing resistor R and the first electrical contact a by using the function of the ADC voltage sampling pin of the controller 114. In particular, the method comprises the steps of,
since the second electrical contact b is grounded, the potential is 0; the voltage value collected by the controller 114 is the voltage value Vx across the resistive heating element R2, and the resistance value of the resistive heating element R2 is calculated based on the voltage value Vx across the voltage dividing resistor R. The formula for the resistive heating element R2 is: (Vbat-Vx)/R-Vx/R2. Where Vbat is the supply voltage of the electric core 111, and Vx is the voltage across the resistance heating element R2.
In order to match the connection design of the circuit 113, the positive electrode of the battery cell 111 is used as a voltage output, and the negative electrode of the battery cell and the second electrical contact b form a closed loop through grounding. In other variable implementations, the second electrical contact b may also be directly connected to the negative pole of the battery cell 111 to form a closed loop.
In other variable implementations, it may be changed that the first electrical contact a is directly or indirectly connected to the negative electrode of the battery cell 111, and the second electrical contact b is connected to the positive electrode of the battery cell 111 through the above switching tube Q1, so that the voltage value obtained by sampling by the controller 114 is the voltage of the voltage dividing resistor R, and the resistance value of the resistance heating element R2 can be calculated according to the same principle. And then the electric core 111 is controlled to output corresponding power according to the resistance value, so that the electric resistance heating element R2 heats the atomized liquid matrix at a proper temperature.
The control end of the switching tube Q1 may be connected to the controller 114, the first end of the switching tube Q1 may be connected to the electric core 111, the control end of the switching tube Q1 may be connected to the electric core 111 through the first resistor R1, and the second end of the switching tube Q1 may be connected to the first end of the voltage dividing resistor R.

The open-drain output is one of the output modes of the chip, and in this embodiment, the controller 114 may be integrated on one chip, so that the chip implements the open-drain output through circuit design and programming. The chip can work in an N-channel open drain mode, namely, the chip does not output voltage: controlling the pin to be grounded when the low level is output; the first resistor R1 acts as a pull-up resistor to control the supply voltage of the pull-up resistor to which the pin voltage is pulled when the pin outputs a high level.
In this embodiment, signal control can be realized only by one switching tube Q1, and an external switching tube is not required, so that circuit devices can be saved, circuit wiring can be simplified, and production cost can be reduced.
A first terminal of the voltage dividing resistor R may be connected to a second terminal of the switching tube Q1, and when the atomizer 120 is coupled to the power supply device 110, the voltage dividing resistor R may be configured to be connected in series with the resistive heating element R2 in the atomizer 120.
The controller 114 may be respectively connected to the second terminal of the voltage dividing resistor R and the control terminal of the switching tube Q1. The controller 114 may be configured to acquire a voltage value Vx across the resistance heating element R2, calculate a resistance value of the resistance heating element R2 based on the voltage value Vx across the voltage-dividing resistor R, and send a high-low level to the switching tube Q1 according to the resistance value of the resistance heating element R2, so as to control the electric core 111 to output power to the electronic atomizer 120.
In a typical alternative embodiment, Vbat can be set to 3.7V, and the voltage dividing resistor R can be set to 1-10 Ω, preferably 1.2-1.8 Ω.
When the atomizer 120 is coupled to the power supply device 110, when the control terminal of the switching tube Q1 is at a low level, the switching tube Q1 may be turned on, and the battery cell 111 may output power to the atomizer 120; when the control terminal of the switch Q1 is at a high level, the switch Q1 is turned off, and the atomizer 120 stops operating.
The controller 114 may control the electrical core 111 to output power to the nebulizer 120 to be substantially constant according to the resistance value of the nebulizer 120. Specifically, the duty ratio of the high level decreases as the resistance value of the nebulizer 120 increases, that is, as the resistance value of the nebulizer 120 increases, the on time of the switching tube Q1 increases. When the resistance value of the atomizer 120 is higher than the preset resistance value, the duty ratio of the high level can be reduced to prolong the conducting time of the switching tube Q1; when the resistance of the atomizer 120 is lower than the preset resistance, the duty ratio of the high level may be increased to shorten the on-time of the switching tube Q1.
It should be noted that, as shown in fig. 2, the power supply device may further include a first electrical contact a and a second electrical contact b, where the first electrical contact a is connected to the second end of the voltage-dividing resistor R, and the second electrical contact b is grounded. When the atomizer 120 is coupled to the power supply device 110, it may be understood that the atomizer 120 is connected between the first electrical contact a and the second electrical contact b. The sampling end of the controller 114 may be connected between the second end of the sampling resistor R and the first electrical contact a. When the atomizer 120 is coupled to the power supply device 110, the voltage dividing resistor R and the resistive heating element R2 are connected in series, and one end of the resistive heating element R2 is grounded (the potential is 0) and the other end is connected to the sampling terminal of the controller 114, so that the controller 114 can collect the voltage value across the resistive heating element R2.
The atomizer 120 may include a resistance heating element R2 and a flag resistor R3, and the resistance value of the atomizer 120 is constituted by the resistance value of the resistance heating element R2 and the resistance value of the flag resistor R3. The flag resistor R3 and the resistive heating element R2 are connected in series, and the flag resistor R3 may be marked with product information of the atomizer 120. The resistance value of the marking resistor R3 may be larger than that of the resistance heating element R2, thereby eliminating the problem of insufficient accuracy of detection of the resistance heating element R2 as a marker.
The product information for the nebulizer 120 may include, among other things, at least one of a flavor of the liquid substrate stored within the nebulizer 120, a viscosity of the liquid substrate, a composition of the liquid substrate, a date of manufacture, an amount of aerosol, an operating temperature, an operating efficiency, or a heating element parameter. In this embodiment, the product information for the atomizer 120 is primarily described as the application of the viscosity of the liquid matrix.
The resistance of the marking resistor R3 can be 5-20 Ω, for example, the marking resistor R3 of the low viscosity liquid matrix is 5 Ω, and the marking resistor R3 of the high viscosity liquid matrix is 10 Ω. The resistance value of the resistance heating element R2 can be 0.8-1 omega. It should be noted that the low and high viscosities of the liquid matrix described in this example are relative terms.
The following description will be made by taking as an example two atomizers 120 each containing a liquid base having high and low viscosities which are different from each other in the amount of smoke emitted:
when the atomizer 120 is combined with the power supply device 110, the controller 114 outputs a high level and a low level to the control end of the switching tube Q1, the switching tube Q1 is turned on when the control end of the switching tube Q1 is at the low level, and the controller 114 further collects the voltage values at the two ends of the resistance heating element R2 and calculates the resistance value of the atomizer 120 based on the voltage values. In this case, the formula is (Vbat-Vx)/R ═ Vx/(R2+ R3).
When the resistance value of the atomizer 120 is calculated to be 6 Ω, it may be determined that the type of the liquid substrate stored in the atomizer 120 is a low-viscosity liquid substrate, and the controller 114 may display the low-viscosity information of the liquid substrate on the display unit of the electronic cigarette 100 product, so that the user of the electronic cigarette 100 can know the low-viscosity liquid substrate. Meanwhile, the controller 114 may also shorten the on-time of the switching tube Q1 to enable the battery cell 111 to supply power to the resistance heating element R2, so that the liquid medium with low viscosity can be sufficiently atomized.
When the resistance value of the atomizer 120 is calculated to be 11 Ω, it may be determined that the type of the liquid substrate stored in the atomizer 120 is a high-viscosity liquid substrate, and the controller 114 may display the high-viscosity information of the liquid substrate on the display unit of the electronic cigarette 100, so that the user of the electronic cigarette 100 can know the information. Meanwhile, the controller 114 may also extend the on-time of the switching tube Q1 to enable the battery cell 111 to supply power to the resistance heating element R2, so that the liquid medium with low viscosity can be sufficiently atomized.
As shown in fig. 3, in order to facilitate resistance detection, product information acquisition and operation process control of the atomizer 120, the atomizer 120 may be structurally provided with three connecting portions in an electrical connection manner between the resistance heating element R2 and the marking resistor R3, respectively:

In the detection circuit, the first connection portion 121 and the third connection portion 123 may be respectively used as detection connection ends for resistance detection, and respectively form a loop with the positive electrode of the battery cell 111 and the voltage dividing resistor R, so as to be used for detecting the resistance of the atomizer 120.
