And, as shown in FIG9 and FIG10, the part 112 of the main shell 10 is provided with an ultrasonic overflow groove 115 surrounding the part 112, which is used to collect the overflow glue generated by melting during ultrasonic welding to prevent the sol from overflowing to the surface of the main shell 10 during ultrasonic welding.

For example, FIG. 11 shows a schematic diagram of an identification element 13a riveted to a portion 112a of the main housing 10 in another embodiment; specifically, a slot 115a is provided on the surface of the portion 112a of the main housing 10; and at least one protrusion 132a is provided on the inner surface of the identification element 13a. During assembly, the identification element 13a is riveted to the outside of the portion 112a of the main housing 10, and the protrusion 132a is inserted into the slot 115a, so that the identification element 13a is stably combined with the main housing 10. In the above embodiment, the identification element 13/13a is rigid.

For example, FIGS. 12 to 14 show schematic diagrams of another embodiment of an identification element 13b formed by molding directly around the main housing 10 from a moldable material; a portion 112b of the main housing 10 is provided with an injection molding groove 115b surrounding the portion 112b in a circumferential direction; the identification element 13b is formed by injection molding a moldable material such as silicone or thermoplastic elastomer (TPE) in the injection molding groove 115b and then curing it, for example, by so-called two-color injection molding to prepare the identification element 13b. And in the implementation shown in FIGS. 12 to 14, a groove 116b adjacent to the portion 112b is provided on the portion 111b of the main housing 10; the groove 116b is used for positioning or sealing the mold in the groove 116b to prevent the moldable material from overflowing the injection molding groove 115b. And after the preparation is completed and the mold is removed, the groove 116b is exposed or opened.

And further according to FIG. 14, the width direction of the portion 112b of the main housing 10 is at least A two-color injection molding groove is provided on one side; during the injection molding process, a material feeding channel is provided, and after the injection molding is completed, the material in the injection molding groove is solidified with the identification element 13b to form an extension portion 133b. The extension portion 133b extends on the portion 112b along the longitudinal direction of the main housing 10.

In this embodiment, when the portion 112b of the main housing 10 of the atomizer 100 is housed or received in the receiving cavity 270 of the power mechanism 200, the flexible identification element 13b molded by double-color injection molding abuts against the open end of the receiving cavity 270 and is also used to provide an airtight seal for the gap between the atomizer 100 and the receiving cavity 270. Alternatively, the flexible identification element 13b is also used to provide a seal between the main housing 10 and the receiving cavity 270 of the power mechanism 200.

And in some implementations, the above identification elements 13/13a/13b can be further doped or include fluorescent materials or luminous materials in addition to the basic polymer plastic and silicone materials, which is more beneficial for improving the color recognition of the identification elements 13/13a/13b.

It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application, but are not limited to the embodiments described in the specification. Furthermore, it is possible for a person of ordinary skill in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to the present application.
