[0025] like Figures 1 to 7As shown, the utility model discloses an anti-leakage electronic cigarette with an airway switch, comprising a shell 1, a mouthpiece 2 arranged at the upper end of the shell 1, a cigarette cartridge assembly 3, a battery 4 and a PCBA assembly 5 arranged in the shell 1, the cigarette cartridge assembly 3 comprising an oil cup 31, a heating core 32 arranged in the oil cup 31 and an oil cup sealing silicone 33 covering the upper end of the oil cup 31, an air outlet 35 is arranged in the middle of the oil cup sealing silicone 33, an air inlet 36 is arranged at the bottom of the oil cup 31, the heating core 32 is a hollow structure and is connected to the air inlet 36 and the air outlet 35, the battery 4 is arranged on one side of the cigarette cartridge assembly 3, and the PCBA assembly 5 is arranged at the bottom of the cigarette cartridge assembly 3. The elastic component 3 is below and includes a support plate 51, a PCBA board 52 arranged on the upper end of the support plate 51, an airway switch 53 slidably connected to the lower end of the support plate 51, and an airway sealing silicone 54 arranged on the upper end of the airway switch 53 and capable of sealing the air inlet 36 at the bottom of the oil cup 31 when the airway switch 53 slides to one end. The PCBA board 52 is provided with a microphone 58 and a dial switch 55 that slides synchronously with the airway switch 53. The battery 4 and the heating core 32 are electrically connected to the PCBA board 52. The lower end of the cigarette holder 2 is connected to the air outlet 35, and the upper end of the cigarette holder 2 is provided with a detachable cigarette holder sealing plug 21.

[0026] During use, when the airway switch 53 is toggled to one side, the airway sealing silicone 54 and the air inlet 36 of the oil cup 31 form a sealed state. At this time, the airflow cannot pass through the inside of the electronic cigarette cartridge assembly 3, so that the electronic cigarette cannot form an airflow, the microphone 58 cannot be triggered, and the electronic cigarette does not work; when the airway switch 53 is toggled to the other side, the airway sealing silicone 54 and the air inlet 36 of the oil cup 31 are in an open state. At this time, the airflow can pass through the inside of the electronic cigarette cartridge assembly 3, so that the electronic cigarette forms an airflow, the microphone 58 is triggered, and the electronic cigarette can work; when the airway switch 53 continues to be toggled to the other side, it will drive the dial switch 55 to move one gear, so that the power of the PCBA can be switched, giving users more taste choices and improving consumer experience.

[0027] In the present invention, after the airway sealing silica gel 54 seals the air inlet 36 of the oil cup 31, the cigarette holder sealing plug 21 is installed on the upper end of the suction nozzle, so that the upper and lower ends of the cigarette cartridge assembly 3 are both in a closed state, so that oil leakage will not occur during transportation.

[0028] In the utility model, a heating core lower end accommodating groove is provided inside the lower end of the oil cup 31, the air inlet 36 is provided at the bottom of the heating core lower end accommodating groove, a heating core upper end accommodating groove is provided in the middle of the lower end of the oil cup sealing silicone 33, the air outlet 35 is provided at the top of the heating core upper end accommodating groove, the upper and lower ends of the heating core are respectively installed in the heating core upper end accommodating groove and the heating core lower end accommodating groove to fix the heating core 32, and an annular oil absorbing cotton 34 is provided in the heating core lower end accommodating groove and between the heating core lower end, the annular oil absorbing cotton 34 can absorb oil from the oil cup 31 and then atomize it through the heating core 32.

[0029] In the present invention, a USB interface 59 is further provided on the PCBA board 52, and the PCBA assembly 5 also includes a microphone silicone 56, which covers the USB interface 59 and the microphone 58.

[0030] In the present invention, the PCBA assembly 5 further includes a switch sealing silicone 57, which is disposed between the airway switch 53 and the housing 1. The switch sealing silicone 57 seals the gap between the housing 1 and the airway switch 53.

[0031] In the utility model, a main air inlet hole and a microphone trigger air inlet hole are provided at the bottom of the shell 1. When the air inlet 36 at the bottom of the oil cup 31 is opened, air can be inhaled through the main air inlet hole and the microphone trigger air inlet hole to achieve the triggering of the microphone 58 and the entry of air.

[0032] In the present invention, a connection contact pin 37 is provided on the outer side of the lower end of the oil cup 31, and the lower end of the connection contact pin 37 is electrically connected to the PCBA board 52, and the upper end of the connection contact pin 37 is electrically connected to the heating core 32. The connection contact pin 37 can facilitate the electrical connection between the PCBA board 52 and the heating core 32, and facilitate assembly.

[0033] In the present invention, a slide groove is provided at the lower end of the support plate 51, and the airway switch 53 is placed in the slide groove. The airway switch 53 can achieve sliding limit and guidance to ensure stable sliding in the slide groove.

[0034] In the present invention, the dip switch 55 is a three-gear dip switch, which can adjust the power when the air inlet 36 is in the open state. When the air inlet 36 is opened, it can continue to adjust one gear, so that the power switching can be controlled to meet the different taste requirements of users.

[0035] In the utility model, the housing 1 comprises an upper housing 11 and a lower housing 12 sealedly connected to the lower end of the upper housing 11, which is convenient for production and assembly.

[0036] The utility model sets an airway switch 53 at the air inlet 36 at the bottom of the oil cup 31, which can realize the switch switching of the electronic cigarette. In this way, the switch can be turned on during production and turned off after testing. Then, the oil cup 31 can be completely closed in cooperation with the cigarette holder sealing plug 21, ensuring that the electronic cigarette does not leak oil during transportation.

[0037] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
