[0045] The side wall of the base body 161 is further provided with a latching protrusion 165 , and correspondingly, the oil cup 11 is provided with a corresponding latching groove or latching hole, and the latching protrusion 165 is latched in the latching groove or latching hole, so that the base 16 is fixedly connected to the lower end opening 110 of the oil cup 11 .

[0046] For further information, please refer again to Figure 3 The oil cup 11 comprises: an oil cup shell 111, a suction nozzle 1111 is provided at the top of the oil cup shell 111, a vent pipe 112 is extended inward from the edge of the suction nozzle 1111, the lower end of the vent pipe 112 is plugged into the connecting pipe 123 of the sealing seat 12, and the vent pipe 112 and the connecting pipe 123 together form a mist outlet channel.

[0047] Please refer again Figure 2 and Figure 3 The battery rod assembly 20 includes: a housing 21, a battery holder 22 disposed in the housing 21, a battery 23 connected to the battery holder 22, a microphone 25 and two spring pins 24. A charging interface 29 is also connected to the bottom of the housing 21, and the charging interface 29 is used to connect an external power cord to charge the battery.

[0048] Please refer again Figures 8 to 12 The battery support 22 includes: a support body 221, a connecting portion 222 connected to the support body 221, and at least two air inlet channels 228 and 229 are provided on the connecting portion 222. The air inlet ends of the air inlet channels 228 and 229 extend to the side walls of the connecting portion 222, and the air outlet ends extend to the top of the connecting portion 222. The top of the connecting portion 222 abuts against the bottom of the base 16, so that the gas entering through the air inlet channels 228 and 229 enters through two independent channels and is transported to the surface of the heating element 15 through the air inlet holes 163 on the base 16. It can be understood that in this embodiment, only two air inlet channels 228 and 229 are used as examples for structural description. In other embodiments, a plurality of other air inlet channels extending like the air inlet channels 228 or 229 can also be provided on the connecting portion 222. Through the design of the above-mentioned independent air inlet ducts 228 and 229, the independent air inlet prevents airflow collision, the airflow is smoother, there is no need to go through a complex airway, the path is shorter, the atomizer core is prevented from being burned, the smoke is fuller, and the user experience is better.

[0049] The connecting portion 222 is also provided with a microphone mounting groove 226, and the microphone 25 is arranged in the microphone mounting groove 226. The connecting portion 222 is also provided with a microphone hole 223, and the microphone hole 223 is connected to the mounting groove 226, so that when the user inhales, the external gas enters the heating element 15 through the air inlet channels 228 and 229, and at the same time, the gas in the mounting groove 226 is extracted through the microphone hole 223 to form a negative pressure. The negative pressure formed in the mounting groove 226 can drive the microphone 25 to open, thereby controlling the battery 23 to supply power to the heating element 15 and start the atomization work. Among them, the periphery of the microphone 25 needs to form a seal with the mounting groove 226, so a microphone seat 26 is also provided in the mounting groove 226, and the microphone 25 is sealed and connected to the microphone seat 26.

[0050] Further, such as Fig. 9 As shown, the side wall of the connecting portion 222 is further provided with an annular air channel 227, and the air inlet ends of the air inlet channels 228 and 229 extend to the bottom of the annular air channel 227. Similarly, the microphone hole 223 is also provided at the bottom of the annular air channel 227.

[0051] A first mounting groove 224 is also provided on the upper side of the annular air duct 227, and a second mounting groove 225 is also provided on the lower side of the annular air duct 227. A first sealing ring 27 is provided in the first mounting groove 224, and a second sealing ring 28 is provided in the second mounting groove 225. When the battery holder 22 is assembled in the outer shell 21, the first sealing ring 27 and the second sealing ring 28 enable a sealed connection between the connecting portion 222 and the outer shell 21.

[0052] Please combine Figure 2 The housing 21 is also provided with one or more air inlets 211, which are connected to the annular air passage 227. Moreover, the size of the air inlet 211 should meet the suction resistance requirements. The diameter of the air inlet 211 ranges from 0.5 to 0.8 mm, such as 0.6 and 0.7 mm.

[0053] Please refer again Fig.13 , the airflow direction in the battery rod assembly 20 of this embodiment is as follows:

[0054] When the user inhales from the suction nozzle 1111 of the oil cup 11, external air enters the annular air channel 227 from the air inlet 211 of the shell 21, and then enters the air inlet hole 163 on the base 16 through the air inlet channels 228 and 229 arranged at the bottom of the annular air channel 227. At the same time, the gas in the mounting groove 226 will be sucked out through the microphone hole 223, and negative pressure will be formed in the mounting groove 226, triggering the microphone 25, and the battery 23 starts to supply power to the heating element 15. The external air is then transported to the heating element 15 through the air inlet 163, carrying the atomized gas and output from the ventilation pipe part 112 to the suction nozzle 1111 for user use.

[0055] In this embodiment, a spring pin 24 is further provided in the air inlet passages 228 and 229 . An air passage is provided in the spring pin 24 . One end of the air passage is connected to the annular air passage 227 , and the other end is connected to the air inlet hole 163 on the base 16 .

[0056] For details, please refer to Figures 10 to 12 The elastic needle 24 includes: an elastic needle body 241, an end cap 242 connected to the upper end of the elastic needle body 241, and a connection portion 243 connected to the lower end of the elastic needle body 241. The elastic needle body 241 is also provided with a plurality of transverse air holes 2411 extending transversely and vertical air holes 2412 extending longitudinally, and the transverse air holes 2411 are all connected to the vertical air holes 2412. The vertical air holes 2412 extend through the end cap to the surface of the end cap 242.

[0057] The end cap 242 is also provided with a slot 2421 that runs horizontally through, and the gas outlet end of the vertical air hole 2412 extends to the bottom of the slot 2421. The spring pin 24 abuts against the electrode 17 after the battery rod assembly 20 is connected to the atomizer assembly 10, and the slot 2421 is provided on the end cap 242 so that the gas flows through the vertical air hole 2412 and is output from the openings on both sides of the slot 2421. The spring pin 24 has both the power supply function and the ventilation function, which saves internal space, has lower costs, smoother airflow, and fuller smoke.

[0058] Please refer again Fig.13 The ventilation process of the spring needle 24 in this embodiment is as follows:

[0059] When the user inhales, the external gas first enters the annular airway 227 from the air inlet 211, then enters the horizontal air hole 2411 of the spring pin 24 from the connected air inlet channels 228 and 229 at the bottom of the annular airway 227, and then is output to the air inlet 163 on the base 16 from the vertical air hole 2412, and then is transported to the heating element 15 from the air inlet 163, and after being mixed with the atomized gas, it flows through the groove 1311 and the mist outlet hole 134 to the ventilation tube part 112, and finally is output to the user from the mouthpiece 1111. At the same time as the external gas enters the annular airway 227, the gas in the mounting groove 226 where the microphone 25 is located is sucked out from the microphone hole 223, thereby triggering the microphone 25 to open, controlling the battery 23 to conduct the circuit that supplies power to the heating element 15, and starting the atomization work.

[0060] The atomizer device of this embodiment realizes the dual functions of conductivity and air conduction by adding an air channel in the bullet needle, thereby saving space, reducing costs, and providing smoother ventilation. At the same time, the air intake channel in the battery rod assembly is designed as two or more independent air intake channels, which reduces airflow collision, shortens the air path, avoids burning of the atomizer core, makes the atomized gas fuller, and provides a better user experience.

[0061] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this.
