[0061] like Figure 5 As shown, in some embodiments, a hook 330 is provided on the outer wall of the enclosing portion 33 , a hook groove 14 is opened on the side wall of the suction nozzle 10 , and the hook 330 is locked in the hook groove 14 .

[0062] Specifically, the circumferential dimension of the enclosure 33 is slightly smaller than the circumferential dimension of the cup body 32 , so that after the oil cup 30 is inserted into the shell 20 , there is a gap between the enclosure 33 and the shell 20 to facilitate the snap-fitting of the suction nozzle 10 with the enclosure 33 .

[0063] There can be multiple hooks 330 and slots 71 respectively corresponding to each other. When assembling the suction nozzle 10, the suction nozzle 10 is pushed to gradually move toward the oil cup 30 until the hook 330 on the enclosure 33 is engaged with the hook slot 14 on the suction nozzle 10 to complete the assembly.

When the assembly is completed, the slot 360 has a limiting effect on the buckle part 921, ensuring that the circuit board 92 is not loose or shaken, ensuring the stability of the installation of the circuit board 92, and reducing the control system failure caused by the looseness of the circuit board 92.

[0081] In some embodiments, the inner wall of the slide groove 36 includes a guide surface 361, which extends from the bottom end of the oil cup 30 to the slot 360. Along the insertion direction of the circuit board 92, the guide surface 361 gradually tilts toward the inner side of the slide groove 36. The guide surface 361 can serve as an assembly guide to facilitate the circuit board 92 to be snapped into the slide groove 36.

[0082] Optionally, guide surfaces 361 are provided on the inner walls of the opposite sides of the slide groove 36 to ensure uniform force during the process of pushing the circuit board 92. During the assembly process of the circuit board 92, the circuit board 92 is pushed in along the length direction of the slide groove 36. As the circuit board 92 gradually slides into the slide groove 36, the two buckling parts 921 of the circuit board 92 contact the two guide surfaces 361 respectively, and then under the guidance of the guide surfaces 361, the buckling parts 921 slide along the guide surfaces 361 into the slot 360 to complete the assembly.

[0083] See also Figure 3 and Fig.10 In some embodiments, a sensing channel 370 is provided on the barrier portion 37; a first air hole 66 is provided on the first sealing member 60, and the upper end of the sensing channel 370 is communicated with the suction port 11 through the first air hole 66; a third sealing column 73 is provided on the side of the second sealing member 70 facing the barrier portion 37, and the third sealing column 73 is inserted into the lower end of the sensing channel 370; a second air hole 730 is provided on the third sealing column 73, and the lower end of the sensing channel 370 is communicated with the card slot 71 through the second air hole 730.

[0084] The upper end of the sensing channel 370 is connected to the suction port 11 through the first air hole 66, and the lower end of the sensing channel 370 is connected to the card slot 71 through the second air hole 730. In this way, when the user sucks through the suction nozzle 10, it will cause the air flow in the card slot 71. The microphone 80 in the card slot 71 senses the flow of the air flow and then sends a trigger signal to the circuit board 92, so that the circuit board 92 controls the battery 91 to heat the ceramic heating element.

[0085] In this embodiment, the microphone 80 is triggered by providing an independent sensing channel 370 on the blocking portion 37, which can effectively isolate the smoke oil from the microphone 80, reduce the risk of oil leakage from the microphone 80, and improve the sensing sensitivity and accuracy of the microphone 80. In addition, the distances between the two ends of the sensing channel 370 and the nozzle 10 and the microphone 80 are relatively short, that is, the air path of the microphone 80 is relatively short, which can effectively speed up the response time of the microphone 80.
