[0029] Please refer to Figures 1-2An electronic atomizer according to an embodiment of the present invention includes a housing and a circuit board 38. The housing has an atomizing chamber 20 and a first fixing frame 35 connected to the atomizing chamber 20. The outer wall of the atomizing chamber 20 is connected to a limiting part 21. The limiting part 21 has a first limiting groove on the side facing the first fixing frame 35, and the first fixing frame 35 has a second limiting groove on the side facing the limiting part 21. The two ends of the circuit board 38 are respectively embedded in the first limiting groove and the second limiting groove, and the first fixing frame 35 and the limiting part 21 are both in contact with the circuit board 38 to limit the displacement of the circuit board 38.

[0030] The two ends of the circuit board 38 are respectively inserted into the first limiting groove of the limiting part 21 of the atomizing chamber 20 and the second limiting groove of the first fixing frame 35, forming a stable clamping structure. The first fixing frame 35 and the limiting part 21 are in close contact with the circuit board 38 to prevent it from shifting or loosening under vibration or external force, and to ensure reliable electrical connection.

[0031] According to some embodiments of this utility model, the top of the atomizing chamber 20 is provided with a protrusion 22, which cooperates with the limiting part 21 to form a limiting groove; the top of the atomizing chamber 20 is also provided with an oil filling hole, and a first sealing silicone 23 is provided in the limiting groove. The first sealing silicone 23 is integrally formed with a sealing plug 33, and the sealing plug 33 is interference-fitted with the oil filling hole to achieve a seal. When filling oil, the user pulls out or lifts the sealing plug 33 to expose the oil filling hole and injects e-liquid. After filling the oil, the sealing plug 33 is pressed back into the oil filling hole, and the elastic deformation of the silicone achieves self-sealing to prevent e-liquid leakage or external dust from entering.

[0032] According to some embodiments of the present invention, the outer wall of the atomizing chamber 20 is recessed inward to form a recess, and a display screen is embedded in the recess, with the outer surface of the display screen flush with the outer wall of the atomizing chamber 20.

[0033] The display screen is electrically connected to the circuit board 38 via wires to display the atomizer status in real time. The display screen is embedded in the recess and fixed with adhesive to ensure that the outer surface is flush with the outer wall of the atomizing chamber 20, without adding extra space and achieving a compact layout.

[0034] According to some embodiments of the present invention, the atomizing chamber 20 further includes an oil-storing cotton 24 and a second sealing silicone 28. The oil-storing cotton 24 has a through first mist outlet channel 25 inside, and a bracket 26 is embedded in the first mist outlet channel 25. The oil inlet end of the bracket 26 is provided with an oil-absorbing cotton 27 and a heating wire. The oil-absorbing cotton 27 is in contact with the oil-storing area of ​​the oil-storing cotton 24, and the heating wire atomizes the e-liquid in the oil-absorbing cotton 27. The second sealing silicone 28 is located at the bottom of the atomizing chamber 20, and an air inlet channel 29 protrudes from the side facing the oil-storing cotton 24. The air inlet channel 29 is inserted into the bracket 26 and is connected to the first mist outlet channel 25.

[0035] According to some embodiments of the present invention, the atomizing chamber 20 further includes a second fixing frame 30, which is inserted into a second sealing silicone 28 to form a cavity and a slot 34. A microphone 31 is provided in the cavity. The second fixing frame 30 is provided with a first air inlet and a through hole 32. The first air inlet is connected to the air inlet channel 29 and is connected to the cavity through the through hole 32. The first fixing frame 35 is provided with a locking block, which is limited to the slot 34.

[0036] When the user inhales, the airflow passes through the first air inlet. Part of the airflow enters the cavity through the through hole 32, triggering the microphone 31 to work. The microphone 31 converts the airflow signal into an electrical signal to control the heating wire to start / stop the atomization function. Another part of the airflow flows into the air intake channel 29. The heating wire heats the e-liquid absorbed by the oil-absorbing cotton 27 to produce atomized vapor. The air in the air intake channel 29 pushes the atomized vapor out along the first mist outlet channel 25.

[0037] According to some embodiments of the present invention, the housing includes a first outer shell 10 and a second outer shell 14. The first outer shell 10 is provided with a first protrusion 11 and a sliding groove 12. The second outer shell 14 is provided with a first groove corresponding to the first protrusion 11. The first protrusion 11 is limited to the first groove. A slidable slider 18 is provided in the sliding groove 12. The slider 18 is connected to an air regulating plate 17. The air regulating plate 17 is provided with a plurality of second air inlets. The slider 18 is driven and moves along the sliding groove 12 under the drive of external force to drive the air regulating plate 17 to adjust the air intake.

[0038] The first outer shell 10 and the second outer shell 14 are positioned and fixed by the engagement of the first protrusion 11 and the first groove, ensuring the stability of the shell structure. The slider 18 is pre-positioned in the slide groove 12 and connected to the air regulating plate 17. The second air inlet on the air regulating plate 17 is aligned with the first air inlet, forming the initial air intake setting. An external force (such as manual sliding by the user) acts on the slider 18, causing it to move along the slide groove 12. The movement of the slider 18 displaces the air regulating plate 17, changing the overlap area between the second and first air inlets, thereby adjusting the air intake.

[0039] According to some embodiments of the present invention, the first outer shell 10 has an opening at one end away from the gas regulating plate 17, and a mouthpiece 15 is provided at the opening. The mouthpiece 15 has a second groove on the side facing the first outer shell 10, and a second protrusion 13 is provided at the corresponding position on the first outer shell 10. The second protrusion 13 is engaged with the second groove. The mouthpiece 15 has a second mist outlet channel 16 on the side facing the atomizing chamber 20, which is connected to the first mist outlet channel 25.

[0040] The mouthpiece 15 is fixed to the opening of the first outer shell 10 by the snap-fit ​​between the second groove and the second protrusion 13, ensuring structural stability. The second mist outlet channel 16 is connected to the first mist outlet channel 25. The atomized vapor enters the second mist outlet channel 16 from the first mist outlet channel 25 of the atomization chamber 20 and is finally discharged through the mouthpiece 15 for the user to inhale, forming a complete atomized vapor delivery path.

[0041] According to some embodiments of the present invention, the electronic atomizer further includes a liquid-absorbing cotton 36, which is wrapped around the outer periphery of the second mist outlet channel 16 and abuts against the mouthpiece 15 and the first sealing silicone 23. The liquid-absorbing cotton 36 absorbs the liquid formed by the condensation of atomized vapor at the mouthpiece 15 to prevent leakage.

[0042] According to some embodiments of the present invention, the electronic atomizer also includes a power supply 37, which is electrically connected to the circuit board 38 and the heating wire via wires to provide power for atomization.

[0043] According to some embodiments of this utility model, the circuit board 38 is provided with a voltage regulating module 39, and the second housing 14 is provided with a button 19 at the position corresponding to the voltage regulating module 39. The button 19 is used to press the voltage regulating module 39 to adjust the output voltage. When the user presses the button 19, it triggers the voltage regulating module 39 to adjust the output voltage, thereby controlling the power of the heating wire and realizing the adjustment of the atomization intensity.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
