The atomizer 200 includes a liquid storage tank 210, an atomization base 220, an atomization core 230, a base 240 and two power-connected electrodes 250. The liquid storage tank 210 is provided with a liquid storage chamber 212. The atomization base 220 is connected from the liquid storage tank 210. The open end is disposed in the liquid storage bin 210 and is blocked at one end of the liquid storage chamber 212.

After the atomizer 200 is connected to the host 100, the first electrode 101 and the second electrode 102 are respectively in contact with the corresponding power electrodes 250, so that the host 100 supplies power to the atomizer 200.

The host 100 includes a control element 110, a first electrode 101, a second electrode 102 and a detection electrode 103.

The control element 110 may be a circuit board or a microcontroller unit (MCU), etc., and the first electrode 101, the second electrode 102 and the detection electrode 103 may be a spring pin, a spring piece or a conductive contact, etc.

As shown in Figure 3, in the first embodiment, after the atomizer 200 is connected to the host 100, the detection electrode 103 of the host 100 contacts the surface of the base 240 and is spaced apart from the power-connecting electrode 250; in other words, the detection electrode 103 103 is not electrically connected to the atomizer 200.

The control element 110 of the host 100 obtains the first signal, thereby confirming the atomizer connected to it. The atomizer 200 is a first type atomizer.

For example, if the atomizer 200 is a constant-power atomizer, after it is connected to the host 100, the detection electrode 103 is not electrically connected to the electrical components on the atomizer 200, but is relatively floating, then the control element 110 detects the first The signal, for example, the first signal is a high-level signal, the controllable element 110 can confirm that the atomizer is an ordinary atomizer with constant power, and the host 100 controls the atomizer 200 to perform atomization with constant power.

Referring to FIG. 4 , FIG. 4 is an enlarged structural diagram of the second embodiment of area B of the electronic atomization device shown in FIG. 2 .

In the second embodiment, after the atomizer 200 is connected to the host 100, the detection electrode 103 is in contact with one of the two power-connected electrodes 250, and then the detection electrode 103 is in contact with the first electrode 101 and the second electrode 102. One of them forms a path, and the control element 110 of the host computer 100 obtains the second signal, thereby confirming that the atomizer 200 connected thereto is a second type atomizer.

Among them, the pin electrically connected to the detection electrode 103 of the control element 110 is set to a high resistance mode, that is, the resistance of the pin is set to a relatively large value, for example, the resistance value can be 8k, 10k or 12k, etc.; while the control element 110 The pin electrically connected to the first electrode 101 and the second electrode 102 is set to a low resistance mode. The resistance of the pin can be 8, 10 or 12, etc., then after the detection electrode 103 forms a path, the current flowing through it Extremely small, thus not affecting the internal circuit of the control element 110 .

For example, if the atomizer 200 is a variable power atomizer, after it is connected to the host 100, the detection electrode 103 forms a path with one of the first electrode 101 and the second electrode 102 through one of the power-connecting electrodes 250, then The control element 110 detects the second signal. For example, the second signal is a low-level signal, that is, after the detection electrode 103 is turned on, the high-level signal on it changes to a low-level signal, thereby confirming that the atomizer 200 is variable. power atomizer, and the host 100 can control the atomizer 200 to perform variable power atomization.

For example, if the host 100 recognizes that the atomizer 200 is a variable power atomizer, it can count the number of electrical connections of the atomizer 200 with respect to the host 100 and output to the atomizer 200 atomization matching the corresponding number of times. power.

For example, the atomizer 200 is a variable power atomizer. The atomizer 200 is electrically connected to the host 100 once, and the host 100 supplies the atomizer 200 with an atomization power of 30 watts; the atomizer 200 is electrically connected to the host 100 twice. If the atomizer 200 is electrically connected to the host 100 three times, the host 100 will supply the atomizer 200 with an atomization power of 50 watts; A reset button can be provided, and the count can be cleared to zero by touching the reset button. Among them, the primary electrical connection, the secondary electrical connection and the third electrical connection are the number of electrical connections of the atomizer 200 with respect to the host 100 recorded by the control element 110 .

Optionally, the atomizer 200 is electrically connected to the host 100 once, and the first program stored on the host 100 is used to drive the atomization process of the atomizer 200; The stored second program drives the atomization process of the atomizer 200 and so on; wherein the first program and the second program drive the atomizer 200 to work according to different power curves.

Optionally, the host 100 recognizes that the atomizer 200 is a variable power atomizer, then the indicator mark on the atomizer lights up, the corresponding control button is activated, and the atomization of the atomizer 200 can also be adjusted by pressing the control button. power.

Further, when the detection electrode 103 forms a path with one of the first electrode 101 and the second electrode 102, the control element 110 is also used to obtain the voltage signal of the detection electrode 103, and regulate the atomization of the atomizer 200 according to the voltage signal. power.

The control element 110 can obtain the pin P1, The terminal pressure at P2 and P3, and supplies a constant current value to the atomizer core 230, and due to the high resistance mode at the detection electrode 103, the current value shunted by the detection electrode 103 is negligible, it can be considered that the detection electrode 103 does not Affects the current value flowing through the pin P1, the first electrode 101, the heating wire or heating film of the atomization core 230, the second electrode 102 and the pin P3.

The resistance values of the first electrode 101, the second electrode 102 and the atomizing core 230 will change during the long-term atomization process, while the current value flowing through the atomizing core 230 remains unchanged, that is, the value of the atomizing core 230 The atomization power will change, and the atomization temperature it provides will also change, which will in turn affect the taste of the aerosol generated. Therefore, in order to keep the atomization core 230 working at constant power or provide a constant atomization temperature, it needs to be adjusted. The size of the current value.

Specifically, as shown in Figure 5, when the voltage change at pin P2 is detected, the contact resistance of the second electrode 102 can be obtained based on the ratio of the voltage difference and current between pin P2 and pin P3, where the first electrode The volt-ampere characteristic curves of 101 and the second electrode 102 are the same, and the original resistances of the first electrode 101 and the second electrode 102 can be obtained in advance, and then the contact resistance of the first electrode 101 can also be obtained. According to the pin P2 and the pin The ratio of the voltage difference and the current at the P3 terminal can be used to obtain the total resistance value. After removing the contact resistance of the first electrode 101 and the second electrode 102 from the total resistance value, the accurate resistance value of the atomizing core 230 can be obtained. The constant power of the core 230 can obtain the current value that should pass through the atomization core 230 at this time, so that the atomization core 230 can be kept working at constant power to provide a stable constant temperature.

The first electrode 101 , the second electrode 102 and the detection electrode 103 can be abutted or welded on the control element 110 . For example, the first electrode 101 and the second electrode 102 are welded to the control element 110, and the detection electrode 103 can be in contact with the control element 110; or, the first electrode 101, the second electrode 102, and the detection electrode 103 are all in contact with the control element. 110 on.

The first electrode 101, the second electrode 102 and the detection electrode 103 may be electrically connected to the control element 110 directly or indirectly.

In this embodiment, the first electrode 101, the second electrode 102 and the detection electrode 103 are all spring needles. The length of the detection electrode 103 is smaller than the length of the first electrode 101 and the second electrode 102.
