A method is described for producing a fastening arrangement of a column-shaped fixing dome of synthetic material on a thin-walled component of synthetic material, for example, a housing. The fixing dome and the thin-walled component are produced separately from each other. Here, a fastening element is integrated in the fixing dome, and an end of the fixing dome is formed as a joining section. In addition, on the inner side of the component, a joining section is built that is matched to the joining section of the fixing dome, in order to build a join connection with said join section for positioning the fixing dome on the component. The join section of the component and/or the join section of the fixing dome are now wetted with an non-curing adhesive. Subsequently, the component and the fixing dome are joined for producing the join connection and through light curing of the adhesive are fixedly connected together.

The invention discloses an electronic cigarette atomizer and a liquid injection method thereof. The electronic cigarette atomizer comprises a shell, an air guide pipe, an atomization assembly and an elastic plug. The first end of the shell is open, and an end plate is arranged in the opposite second end. The atomization assembly is arranged at the first end of the shell in a matched mode. One end of the gas guide pipe is inserted into the atomization assembly, and the other end of the gas guide pipe penetrates out of the end plate. A liquid storage bin surrounding the periphery of the gas guide pipe is formed between the gas guide pipe and the inner wall of the shell. A liquid injection hole communicated with the liquid storage bin is formed in the end plate. The elastic plug is arranged on the end plate in a matched mode to cover and seal the liquid injection hole. According to the electronic cigarette atomizer, the liquid storage bin is closed. When liquid is injected, the elastic plug is punctured by the liquid injection needle to enter the liquid storage bin.
