Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic atomizer protection technology, specifically a protective shell for an easily replaceable electronic atomizer. Background Technology
[0002] In the field of electronic atomizers, protective shells play a crucial role as an important component. Electronic atomizers, especially those used in products such as e-cigarettes, face a variety of potential risks in daily use. Their internal structure is delicate, containing key components such as atomizing devices, e-liquid reservoirs, and electrical components. These components need to be effectively protected to maintain the normal operation of the atomizer and extend its service life. Therefore, an easily replaceable protective shell for electronic atomizers is required.
[0003] When the protective shell is damaged due to daily wear and tear, collisions, or other reasons, it needs to be replaced. However, some protective shells are integrated with the main body of the e-vaporizer, or the connection is relatively tight, requiring professional tools and complicated disassembly steps to complete the replacement. This not only consumes a lot of time and energy for users, but also may cause damage to other parts of the e-vaporizer due to improper operation by non-professionals, further increasing the repair cost. Utility Model Content
[0004] The purpose of this utility model is to provide a replaceable protective shell for electronic atomizers, solving the problem mentioned in the background art that most existing electronic atomizer protective shells are either integrated or cumbersome to disassemble, making replacement inconvenient. To achieve the above objective, this utility model provides the following technical solution: a replaceable protective shell for electronic atomizers, comprising an electronic atomizer body;
[0005] The outer shell assembly includes a protective shell disposed on the outside of the electronic atomizer body. The protective shell has a wrapping compartment inside and an installation port on one side. A limiting soft band is fixedly connected to one side of the protective shell, and a Velcro female side is fixedly connected inside the limiting soft band. A Velcro female side is fixedly connected to the other side of the protective shell.
[0006] A top cover assembly, the top cover assembly including an extension block, the extension block having a connecting rope inside, and a rubber cap fixedly connected to the other end of the connecting rope.
[0007] More preferably, the outer shell assembly is disposed on the outside of the electronic atomizer body, and the top cover assembly is disposed on top of the electronic atomizer body. By installing the outer shell assembly, the protective shell can be fitted onto the outside of the electronic atomizer body through the installation port. After the limiting soft band is wrapped around it, the female side of the Velcro and the male side of the Velcro are glued and fixed, thereby firmly wrapping the electronic atomizer body in the enclosure, effectively preventing it from being subjected to external impact and friction, and playing a good protective role. At the same time, this installation method is simple and convenient, and it is easy to quickly install or remove the protective shell to clean and inspect the electronic atomizer body, thereby improving convenience.
