Description

Technical Field

[0001] The utility model relates to the technical field of high-speed hair dryers, and more specifically, to a heating component and a hair dryer. Background Art

[0002] Compared with ordinary hair dryers, high-speed hair dryers have significantly improved air speed and drying efficiency. The key difference lies in the use of a more powerful motor and more precisely designed fan blades, which greatly increase the wind speed and thus achieve a faster drying effect.

[0003] However, in most existing high-speed hair dryers, a technical challenge is the assembly efficiency of the thermal cut-off and thermal fuse. These key components are usually fixedly installed on the PCBA bracket, and the assembly process requires installing the support piece first and then connecting the thermal cut-off and thermal fuse, which leads to a reduction in assembly efficiency. Summary of the Invention

[0004] The utility model aims to solve one of the technical problems in the related technologies to a certain extent. For this purpose, the utility model provides a heating component, which pre-installs the thermal cut-off and thermal fuse on the support piece and connects them to the PCBA bracket, avoiding the situation of assembling these key components in a limited space. This setting simplifies the assembly process of the high-speed hair dryer and improves the efficiency.

This avoids the installation scenario of assembling the thermal cut-off and thermal fuse in the limited space of the PCBA bracket. Through the above settings, the assembly process of the key components in the high-speed hair dryer is simplified, the assembly efficiency is improved, and it also helps to maintain the overall performance and stability of the high-speed hair dryer.
