[0030] Please refer to Figures 1-4An electronic atomizer according to an embodiment of the present invention includes a mouthpiece assembly and a housing. The mouthpiece assembly includes a mouthpiece body 10 and a fixing shaft 12. The mouthpiece body 10 is provided with a vapor outlet channel 11. A buckle 13 is provided at one end of the fixing shaft 12 away from the mouthpiece body 10. A first atomizing core 25 and a second atomizing core 26 are provided inside the housing. The first atomizing core 25 and the second atomizing core 26 are independent of each other and store different e-liquids respectively. A first through hole 44 is provided in the housing corresponding to the position of the first atomizing core 25, and a second through hole 45 is provided in the housing corresponding to the position of the second atomizing core 26. A slot 43 is also provided in the housing. Two first elastic pieces 40 are provided above the slot 43. When the mouthpiece assembly is assembled into the housing, the buckle 13 and the slot 43 form a snap-fit ​​engagement. The two first elastic pieces 40 elastically press against the fixing shaft 12, so that the vapor outlet channel 11 can selectively connect with the first through hole 44 or the second through hole 45.

[0031] When the mouthpiece assembly is assembled onto the housing, the fixing shaft 12 is confined between the two first elastic plates 40. At this time, the first elastic plates 40 will undergo elastic deformation, thereby tightly abutting against the fixing shaft 12 and ensuring a stable connection of the mouthpiece assembly in the initial state. Simultaneously, the buckle 13 connected below the fixing shaft 12 is confined in the slot 43, further enhancing the connection stability between the mouthpiece assembly and the housing. The housing contains independent first atomizing cores 25 and 26, which store different e-liquids respectively, and correspondingly have first through holes 44 and second through holes 45. The mist outlet channel 11 of the mouthpiece assembly can be selectively connected to any of the through holes through a rotational operation, enabling switching between multiple flavors.

[0032] Specifically, the two first elastic plates 40 are arranged opposite each other, and the nozzle assembly also includes a fixing block 14. The two fixing blocks 14 are respectively located on the outside of the fixing shaft 12 and are arranged opposite each other. Each fixing block 14 has a groove 15 on its opposite side. The outer side of the first elastic plate 40 is connected to a protrusion 42. When the nozzle assembly is rotated to make the mist outlet channel 11 connect with the first through hole 44 or the second through hole 45, the protrusion 42 is inserted into the groove 15 to achieve a limiting position.

[0033] When the user rotates the nozzle body 10, it drives the fixed shaft 12 and the fixed block 14 to rotate synchronously. When the mist outlet channel 11 rotates to align with the first through hole 44 or the second through hole 45, the protrusion 42 is engaged in the groove 15 under the elastic action of the first elastic piece 40, forming a mechanical limit. The user can confirm the switch to the correct position by touch (the tactile sensation when engaged) or hearing (the "click" sound when engaged).

[0034] Specifically, a second elastic sheet 41 is provided between the two first elastic sheets 40. When the nozzle assembly is assembled into the housing, the first elastic sheet 40 and the second elastic sheet 41 elastically press against the fixing shaft 12. When the fixing shaft 12 of the nozzle assembly is inserted into the housing, the first elastic sheet 40 and the second elastic sheet 41 undergo elastic deformation synchronously, jointly applying a pressure against the fixing shaft 12, thereby enhancing the reliability of the connection between the nozzle assembly and the housing.

[0035] Specifically, the housing includes a first outer shell 20, a second outer shell 21, and a third outer shell 22. The second outer shell 21 abuts against the first outer shell 20 and forms a receiving space. The third outer shell 22 is located within the receiving space and has a first receiving cavity 27 and a second receiving cavity 28 that are isolated from each other. The first receiving cavity 27 is used to receive the first atomizing core 25, and the second receiving cavity 28 is used to receive the second atomizing core 26. The outer wall of the third outer shell 22 is provided with a first protrusion 23 and a second protrusion 24. The inner wall of the first outer shell 20 is provided with a first groove 15, and the inner wall of the second outer shell 21 is provided with a second groove 15. When the housing is assembled, the first protrusion 23 engages with the first groove 15, and the second protrusion 24 engages with the second groove 15.

[0036] During assembly, the third outer shell 22 is snapped into the first outer shell 20, and the third outer shell 22 is snapped into the second outer shell 21 to complete the assembly of the shell. The first atomizing core 25 is installed into the first receiving cavity 27 of the third outer shell 22, and the second atomizing core 26 is installed into the second receiving cavity 28. The isolation structure of the two receiving cavities prevents cross-contamination of e-liquid.

[0037] Specifically, the second outer shell 21 is provided with an air inlet, and the bottom of the third outer shell 22 is provided with an opening. A sealing silicone 35 is provided at the opening. The sealing silicone 35 has a first air hole at the position corresponding to the first atomizing core 25 and a second air hole at the position corresponding to the second atomizing core 26.

[0038] Specifically, the electronic atomizer also includes a first microphone 31 and a second microphone 32. The sealing silicone 35 is provided with a first limiting cavity and a second limiting cavity for fixing the first microphone 31 and the second microphone 32, respectively. The sealing silicone 35 is also provided with a first microphone airway 33 and a second microphone airway 34. The first microphone airway 33 is connected to the first air hole and the first limiting cavity, and the second microphone airway 34 is connected to the second air hole and the second limiting cavity.

[0039] Specifically, the electronic atomizer also includes a circuit board 30, and the first microphone 31 and the second microphone 32 are both electrically connected to the circuit board 30.

[0040] When a user inhales into the e-cigarette, external air enters the e-cigarette through the air inlet on the second outer shell 21. The sealing silicone 35 has a first limiting cavity and a second limiting cavity, which are used to fix the first microphone 31 and the second microphone 32, respectively. Simultaneously, the sealing silicone 35 also has a first microphone airway 33 and a second microphone airway 34. The first microphone airway 33 is connected to the first air hole and the first limiting cavity, and the second microphone airway 34 is connected to the second air hole and the second limiting cavity. When the mouthpiece assembly is connected to the first air hole, air passes through the first air hole, and some of the airflow enters the first microphone airway 33. The airflow within the first microphone airway 33 creates a pressure change, triggering the first microphone 31. The first microphone 31 acts as an airflow sensing switch; when triggered, it sends a signal to the circuit board 30, informing it that an inhalation action has occurred, thereby activating the atomization operation of the first atomizing coil 25. When the mouthpiece assembly is connected to the second air hole, air will pass through the second air hole, and some of the airflow will enter the second microphone airway 34. The airflow flows in the second microphone airway 34, generating air pressure changes, which triggers the second microphone 32. The second microphone 32 acts as an airflow sensing switch. After it is triggered, it will send a signal to the circuit board 30 to inform the circuit board 30 that a suction action has occurred, thereby starting the atomization work of the second atomizing core 26.

[0041] Specifically, the electronic atomizer also includes a power supply 37, which is electrically connected to a circuit board 30.

[0042] Specifically, the electronic atomizer also includes a charging port 36 and an indicator light 38. The second housing 21 has a first clearance opening corresponding to the position of the charging port 36 and a second clearance opening corresponding to the position of the indicator light 38. The charging port 36 and the indicator light 38 are both electrically connected to the circuit board 30.

[0043] When the e-cigarette's battery is low, the user inserts the charging cable into charging port 36. Charging port 36 is electrically connected to circuit board 30, and the charging cable draws power from external power source 37 into circuit board 30 and then into power source 37 via charging port 36. Circuit board 30 has a built-in charging management module that comprehensively manages the charging process. First, circuit board 30 detects the current battery status of power source 37 and adjusts the charging current and voltage based on the detection results to ensure efficient and safe charging. During charging, circuit board 30 continuously monitors the battery level of power source 37. When the battery reaches full charge, it automatically cuts off the charging circuit to prevent overcharging from damaging power source 37. Indicator light 38 is electrically connected to circuit board 30, and circuit board 30 generates corresponding control signals based on different operating states of the e-cigarette. For example, under normal operating conditions, indicator light 38 displays red; during charging, indicator light 38 displays yellow; and when the battery is low, indicator light 38 flashes rapidly to remind the user to charge it in time.

[0044] Specifically, the third housing 22 is provided with a positioning notch 29, and the end of the circuit board 30 is embedded in the positioning notch 29 and forms a limiting fit with the side wall of the positioning notch 29.

[0045] The positioning notch 29 of the third housing 22 is precisely designed to match the end of the circuit board 30. Its dimensions (length, width, depth) and shape (such as rectangle, trapezoid) are perfectly matched to the end of the circuit board 30, ensuring that the circuit board 30 can be accurately embedded during assembly.

[0046] 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.
