Due to the surface tension, the atomized liquid will not enter the vent pipe 177 from the buffer cavity 110 .

Specifically, in this embodiment, a certain interval is formed between the lower end surface of the support tube 15 and the upper end surface of the liquid supply tube 25 , and the inner diameter of the support tube 15 may be larger than the outer diameter of the liquid supply tube 25 .

The atomizer 1 may also include at least one second electrode post 16 embedded on the base assembly 13 along the longitudinal direction. The upper end of the second electrode column 16 can communicate with the heating cavity 1710 and be close to the electrode lead 173 . Usually, there are two second electrode columns 16 , and the two second electrode columns 16 are electrically connected to two electrode leads 173 respectively. When the atomizer 1 is inserted into the host machine 2, the lower ends of the two second electrode posts 16 (the ends facing the battery 22 ) are respectively in contact with the upper ends of the two first electrode posts 26 (the ends facing the nozzle cover 12 ). Pass. Each second electrode column 16 and the corresponding conductive first electrode column 26 form an electrode assembly 60 , and the electrode assembly 60 is preferably an elastic electrode assembly.

Further, the electronic atomization device may also include a liquid level detection system to detect whether the atomized liquid in the buffer cavity 110 is sufficient, and the liquid transmission component 23 may start or stop the liquid supply according to the detection result of the liquid level detection system, for example, The liquid supply is turned on when the test result is lack of liquid, and the liquid supply is stopped when the test result is liquid. The liquid level detection method of the liquid level detection system is not limited, and various methods such as capacitance and resistance are acceptable, as long as the free atomized liquid can be detected.

In this embodiment, the liquid supply pipe 25 is conductive, and it can be made of conductive materials such as metal. The upper end of the liquid supply pipe 25 communicates with the buffer cavity 110 , and the lower end communicates with the liquid transmission assembly 23 . One end of the liquid supply pipe 25 communicating with the liquid transmission component 23 can be electrically connected with the controller 24 .

If the liquid supply pipe 25 and the heating element 172 contact the atomized liquid at the same time and form a path through the atomized liquid, the atomized liquid in the controller 24, the liquid supply pipe 25, the buffer chamber 110, the heating element 172, and the electrode The component 60 and the controller 24 are sequentially connected to form a liquid level detection circuit loop, which means that the atomized liquid in the buffer cavity 110 is sufficient, and the liquid transmission component 23 can stop supplying liquid to the buffer cavity 110 to avoid atomization in the buffer cavity 110 Too much liquid leads to liquid leakage; the atomized liquid is gradually consumed with suction and heating, and the free atomized liquid in the buffer cavity 110 will immediately replenish the liquid accumulation part 178, the liquid guide part 176 and the liquid suction part 171 until broken circuit. When there is an open circuit between the liquid supply pipe 25 and the heating element 172, it means that the atomized liquid in the buffer chamber 110 is insufficient, and the liquid transmission assembly 23 can be opened to supply liquid to the buffer chamber 110, and the supplied atomized liquid is first filled with liquid Part 178, liquid guiding part 176 and liquid absorbing part 171, when a certain amount of free atomized liquid appears in the buffer cavity 110, there will be a passage between the liquid supply pipe 25 and the heating part 172, and the liquid transmission assembly 23 will stop the supply. liquid.

In this embodiment, whether there is atomized liquid in the buffer cavity 110 is judged by the on-off of the circuit between the liquid supply pipe 25 and the electrode assembly 60. The structure is simple, the result is reliable, and the response of automatic liquid injection is fast, which can avoid dry burning and liquid leakage . Specifically, the controller 24 can be used to determine whether a passage is formed between the liquid supply pipe 25 and the electrode assembly 60, and if so, output a closing signal to the liquid transmission assembly 23 to allow the liquid transmission assembly 23 to stop supplying liquid; The liquid transmission component 23 outputs an opening signal for enabling the liquid transmission component 23 to start supplying liquid. The closing signal and/or opening signal can be transmitted to the liquid transmission component 23 immediately, so that the liquid transmission component 23 immediately stops the liquid supply and/or starts the liquid supply. In other embodiments, the controller 24 may also include a delay module, which is used for delaying the start or stop of the liquid transmission component 23 .

In another embodiment, the liquid level detection system can also be used to control the liquid transmission assembly 23 to start the liquid supply when the circuit between the liquid supply pipe 25 and the electrode assembly 60 is detected, and the liquid transmission assembly 23 stops pumping after a certain period of time. liquid. Most of the atomized liquid pumped by the liquid transmission component 23 can be stored by the liquid accumulation part 178 , the liquid guide part 176 and the liquid suction part 171 , and can be heated and atomized by the heating part 172 . When the atomized liquid is consumed, the system will detect the disconnection between the liquid supply pipe 25 and the electrode assembly 60 again, and then turn on the liquid transmission assembly 23 to continue pumping liquid. The pumping time and the pumping volume can be determined according to the parameters such as the liquid supply speed, the atomization speed, and the capacity of the buffer chamber 110. For example, the pumping time can be 1~5s, and the pumping volume can be 15~50mg.

The two ends of the liquid supply pipe 25 can conduct electricity, and the liquid supply pipe 25 can be connected to the atomized liquid in the buffer chamber 110 and the controller 24 through the two ends of the pipe. The two end surfaces of the first electrode column 26 and the second electrode column 16 can conduct electricity, the lower end surface of the first electrode column 26 is connected with the controller 24, and the upper end surface of the first electrode column 26 can be connected with the lower end of the second electrode column 16. The end surfaces are in contact with each other, and the upper end surfaces of the second electrode pillars 16 are in conduction with the heating element 172 . Specifically, the outer circumference of the liquid supply pipe 25, the first electrode column 26, and the second electrode column 16 are insulated, for example, the outer wall surface of the liquid supply pipe 25 and/or the first electrode column 26 and/or the second electrode column 16 can be insulated. Wrapping the insulating layer (such as insulating sleeve, insulating coating, silicone flange, etc.) The tube 25 and the electrode assembly 60 are misjudged as a passage, thereby preventing the heating element 172 from burning dry. Specifically, the upper end of the liquid supply pipe 25 communicates with the buffer cavity 110 and the area other than the controller 24 at the lower end, and the electrode assembly 60 communicates with the heating cavity 1710 at the upper end and the area other than the controller 24 at the lower end. Absolute insulation between the surface and the outer peripheral surface of the electrode assembly 60 . In this embodiment, the outer wall of the liquid supply pipe 25 is wrapped by the insulating sealing seat 132 and the sealing sleeve 27 , so that the liquid supply pipe 25 and the electrode assembly 60 are insulated from each other in a predetermined area.

Further, in order to further improve the reliability of the circuit between the liquid supply pipe 25 and the electrode assembly 60 , an open circuit detection module can also be set to detect the open circuit of the liquid supply pipe 25 and/or the electrode assembly 60 . By detecting the open circuit of the liquid supply pipe 25 itself, the problem of continuous liquid supply and serious liquid leakage caused by the open circuit caused by the failure of the liquid supply pipe 25 itself can be prevented. By detecting the open circuit of the electrode assembly 60, if the electrode assembly 60 fails and causes an open circuit, it is determined that the second electrode column 16 and the first electrode column 26 are not conducting, and it is determined that the atomizer 1 is not connected to the host machine 2, and the system does not work. In some embodiments, the open circuit detection can be realized by redundant design. For example, at least two parallel wires can be drawn from the controller 24 to connect to the liquid supply pipe 25. If the open circuit is caused by the failure of the liquid supply pipe 25, the controller 24 outputs a closing signal to stop liquid supply to the liquid delivery assembly 23 .

Furthermore, each liquid supply pipe 25 and the electrode assembly 60 on the corresponding side constitute a liquid level detection circuit, so as to realize the double-sided liquid level detection of the buffer chambers 110 on both sides, so as to take into account the scene where the electronic atomization device is used at an angle . During detection, if the liquid level detection on both sides is open, the liquid transmission assembly 23 stops supplying liquid; if one side of the passage is open, the liquid transmission assembly 23 stops supplying liquid; , then the liquid delivery assembly 23 turns on the liquid supply. Understandably, in other embodiments, the liquid level detection circuit may also be provided on only one side.

It can be understood that in other embodiments, the liquid level detection of the nebulizer 1 can also be performed through other liquid level detection structures, for example, a liquid level detection member can also be additionally provided in the buffer chamber 110 for liquid level detection.

The voltage value is measured in real time through the AD_T pin of the MCU. Since the atomized liquid usually has a high resistance value, when the atomized liquid in the atomizer 1 is sufficient, the atomized liquid is passed between the liquid supply pipe 25 and the heating element 172 connected to form a circuit, and the detected resistance Rs is equal to a low resistance value; when the atomized liquid in the atomizer 1 is insufficient, the liquid supply pipe 25 and the heating element 172 cannot be connected to form a circuit through the atomized liquid, and the detected The resistance value Rs is equal to the high resistance value.

The circuit of this embodiment is simple and low in cost, and the capacity state of the atomized liquid in the atomizer 1 can be deduced without complicated calculation methods; when the capacity state of the atomized liquid in the atomizer 1 does not need to be detected, The detection output voltage is turned on, which has good safety; in addition, the circuit does not need a sensor, and the detection terminal can be used as a detection terminal through a wire, which is simple to implement.
