Through setting up piece 305 that resets, when cigarette holder subassembly 300 assembles in place, can reduce the vibrations between cigarette holder subassembly 300 and the stock solution subassembly 400 to make the connection more firm.

When the cigarette holder component 300 and the liquid storage component 400 need to be moved relatively, when liquid is injected into the liquid storage cavity 110 through the liquid injection hole 143, the liquid injection cover 301 can be pulled upwards along the axial direction of the upper cover 15, so that the inner wall of the liquid injection cover 301 is separated from the assembling surface 155, during the upward sliding process of the liquid injection cover 301, the liquid injection cover 301 drives the limiting ring 304 to slide upwards along the axial direction relative to the cigarette holder 302, at this time, the reset piece 305 is further compressed during the upward moving process of the limiting ring 304, when the upper end surface of the limiting ring 304 is abutted against the lower end surface of the fixing body 3031, the lower end surface of the liquid injection cover 301 and the upper end surface of the upper cover 15 are located on the same horizontal plane or above the upper end surface of the upper cover 15, at this time, the liquid injection cover 301 can be pushed along the radial direction of the upper cover 15, when the liquid injection cover 301 slides radially relative to the upper cover 15, the liquid injection cover 301 drives the liquid injection seat body 3021 to slide, the pouring hole 143 of the lid 15 can be exposed. Further, the liquid injection hole 143 is a through hole penetrating through the upper surface and the lower surface of the upper lid 15, optionally, the liquid injection hole 143 is disposed on one side of the upper lid 15 deviating from the central axis of the upper lid 15, the two limiting protrusions 152 are disposed on the other side of the upper lid 15 deviating from the central axis relative to the liquid injection hole 143, the two limiting protrusions 152 are disposed in parallel, when the two opposite side walls of the mouthpiece holder body 3021 are embedded in the sliding groove 154, the mouthpiece holder body 3021 can shield the liquid injection hole 143, and when the mouthpiece holder body 3021 slides in the sliding groove 154 in a direction away from the liquid injection hole 143, the liquid injection hole 143 can be exposed, so that liquid injection can be performed through the liquid. Through setting up piece 305 that resets, when finishing annotating the liquid, and push cigarette holder 302 back to the original position, because the elastic restoring force of piece 305 that resets, automatic spacing ring 304 of pushing down, spacing ring 304 drives annotates liquid lid 301 and moves down, makes the inner wall of annotating liquid lid 301 support and holds on the assembly surface 155 of upper cover 15 at last, prevents to annotate the radial movement of liquid lid 15. At this point the mouthpiece component 300 is again locked and cannot be filled.

The mouthpiece 306 is inserted into the mounting portion 3011, and a smoking hole 3061 for communicating the outside with the smoking port 112 is formed in the mouthpiece 306. In order to prevent the side wall of the mouthpiece 306 from being in rigid contact with the inner wall of the mounting portion 3011 and causing abrasion between the side wall of the mouthpiece 306 and the inner wall of the mounting portion 3011, or to seal a gap between the side wall of the mouthpiece 306 and the inner wall of the mounting portion 3011, a sealing ring 3062 is interposed between the mouthpiece 306 and the mounting portion 3011, and the sealing ring 3062 is made of an elastic material with good sealing performance, such as silica gel or rubber.
