As shown in FIGS. 7 and 8, the suction nozzle 100 is also provided with a guide post 120 for sealing the liquid injection hole 214.

As shown in FIGS. 9 and 10, in one or more embodiments, the suction nozzle 100 and the atomization assembly 200 are connected by a snap connection. In a specific embodiment, a first groove 130 is provided on the side wall of the suction nozzle 100, and a first protrusion 215 is provided on the side wall of the atomization assembly 200. The first groove 130 and the first card The protrusions 215 cooperate, so that the suction nozzle 100 and the atomizing assembly 200 are connected in a snap-fit manner. It can be understood that, in other embodiments, the first protrusion 215 may be provided on the side wall of the suction nozzle 100 and the first groove 130 may be provided on the side wall of the atomization assembly 200.

The assembly process of the atomization assembly 200 and the suction nozzle 100 is briefly described below. Firstly, the heating component 220 is installed in the accommodating cavity 212 of the atomizing body 210 so that the heating component 220 is located at the first position as shown in FIG. 5. When the heating component 220 is in the first position, the base 225 of the heating component 220 is flush with the bottom of the atomizing body 210, and the sealing element 224 is located at the liquid outlet 217 between the containing cavity 212 and the liquid storage cavity 211, thereby blocking The communication between the containing cavity 212 and the liquid storage cavity 211 prevents the smoke liquid from flowing into the liquid guiding element 221 from the liquid storage cavity 211. At this time, the atomizing body 210 forms a semi-sealed structure, and only the liquid injection hole 214 is directly connected to the outside atmospheric pressure. Then, liquid such as smoke liquid can be injected from the liquid injection hole 214 at the upper end of the atomizing body 210. When the liquid storage cavity 211 is filled with liquid, the liquid in the liquid storage cavity 211 will not flow out of the liquid injection hole 214 under the action of the external atmospheric pressure, thereby avoiding the liquid leakage of the atomization assembly 200 during the production process problem. Then, the suction nozzle 100 is covered on the atomizing assembly 200 filled with liquid, as shown in FIG. 8. At this time, the guide post 120 in the mouthpiece 100 seals the liquid injection hole 214 of the atomization assembly 200, so that the atomization assembly 200 forms a completely sealed device, which can achieve long-term storage of the smoke liquid and prevent liquid leakage.

It can be understood that the atomization device of this embodiment is in the factory state, the atomization assembly 200 and the suction nozzle 100 are assembled together and separated from the power supply assembly 300, and the liquid storage cavity 211 of the atomization assembly 200 is completely sealed, which can achieve Long-term storage of smoke liquid and prevent liquid leakage. When in use, as shown in FIG. 2, the user inserts the atomizing assembly 200 containing liquid into the power supply assembly 300 that provides electrical energy to the atomizing assembly 200. At this time, the pushing structure 310 in the power supply assembly 300 is in contact with the base 225 of the heating assembly 220, and the heating assembly 220 is pushed to move relative to the atomizing body 210 toward the suction nozzle 100, so that the heating assembly 220 moves from within the receiving cavity 212 The first position moves to the second position. When the heating component 220 is in the second position, the liquid guiding element 221 is located at the liquid outlet 217, so as to communicate with the liquid storage cavity 211, and the liquid can flow from the liquid storage cavity 211 into the liquid guiding element 221. After the liquid guiding element 221 is energized The atomization of liquid can be realized. Since the liquid guiding element 221 cannot touch the liquid in the liquid storage cavity 211 during the storage process of the atomization assembly 200, it can only be contacted during use, which reduces the time that the liquid guiding element 221 contacts the liquid, and thus can avoid liquid leakage. leak. In addition, as shown in FIG. 2, when the liquid guiding element 221 is pushed to communicate with the liquid storage cavity 211 of the atomization body 210, the liquid guiding element 221 extends into the liquid storage cavity 211 through the liquid outlet 217, and is The volume of the liquid in the liquid cavity 211 is compressed to a certain extent, so that the liquid in the liquid storage cavity 211 can quickly penetrate into the liquid guiding element 221, which shortens the time for the liquid to penetrate the liquid guiding element 211.
