Benefits of technology
The present invention aims to provide a diffuser module that can be coupled with a housing without compromising air flow. The design is also smaller and lighter, allowing for a more portable and efficient electric blower. Additionally, a rotation module is provided with assembly guide parts to enhance coupling force. Overall, the invention improves assembly and performance of the diffuser module and the electric blower.
Problems solved by technology
The conventional electric blower as disclosed in the Patent Document below, for example, has problems in coupling the impeller cover with the housing, in that air flow in the diffuser may be disturbed due to the reduction in size, it is difficult to align the front and the impeller cover on the same axis, it is difficult to make the blower smaller and lighter due to the coupling structure of the impeller cover and the housing, and durability and robustness are deteriorated.
