[0024] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0025] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0026] like Figs. 1-3 As shown, a hair dryer with temperature control and distance measurement includes a main unit, which includes a main unit housing 2 and a handle 1 for easy grip and operation. A PCBA board 6 is installed within the main unit housing 2 and connected to other internal components, controlling the hair dryer's temperature and distance measurement functions. The PCBA board 6 automatically adjusts the hair dryer's power based on distance measurement data, achieving intelligent temperature control and protection for the hair and scalp.

[0027] A heating wire bracket 8 is located outside the PCBA 6. This bracket supports and secures the heating wire 7. The heating wire 7's heating effect ensures that the hair dryer quickly generates hot air when turned on, for drying and styling hair. The bracket 8 is assembled in a ring shape on one side of the PCBA 6, ensuring that the heating wire 7 is evenly distributed around the outside of the PCBA 6 to optimize airflow distribution and heat dissipation. Furthermore, to reduce heat transfer to the distance measuring components, the bracket 8 is designed as an independent insulation structure, ensuring efficient heat insulation.

[0028] A distance measuring lens 4 is installed in the host housing 2 away from the side of the PCBA board 6, and is located at the front end of the air outlet to help the normal operation of the distance measuring function. The distance measuring lens 4 is a certain distance away from the PCBA board 6 to form a heat insulation cavity 11 to avoid the adverse effects of high temperature on the distance measuring induction IC 10. The distance measuring induction IC 10 is installed at the inner side end of the distance measuring lens 4, accurately senses the distance from the user's scalp, and ensures that the temperature is moderate when the user uses the hair dryer. The distance measuring plate 9 is tightly attached to the inner side end of the distance measuring induction IC 10, and together with the distance measuring induction IC 10 forms a distance measuring assembly. The distance measuring induction IC 10 and the distance measuring plate 9 are both electrically connected to the PCBA board 6, and the PCBA board 6 receives the data feedback from the distance measuring assembly to dynamically control the temperature by adjusting the power output of the heating wire 7.

[0029] The PCBA board 6, the heating wire support 8, the distance measuring plate 9, and the fixing support, including the air outlet on the fixing support, together form an independent heat insulation cavity 11 around the air outlet, which isolates the distance measuring induction IC 10 from the heat source, ensuring that the distance measuring system is not directly affected by the heat source, and ensuring the distance measuring accuracy and long-term stability. The design of the heat insulation cavity 11 effectively reduces the interference of heat on the distance measuring assembly, thereby ensuring the efficiency of the distance measuring and temperature adjusting function.

[0030] In the preferred technical solution of the structure, it also contains a fixing support 5 installed between the PCBA board 6 and the distance measuring lens 4, and used to support the distance measuring lens 4, the distance measuring induction IC 10 and the distance measuring plate 9, so as to facilitate the stable installation and accurate positioning of the distance measuring assembly. The design of the fixing support 5 not only strengthens the support stability of the distance measuring assembly, but also further enhances the heat insulation effect in the heat insulation cavity 11, avoiding the impact of high temperature on the distance measuring system.

[0031] A mica cylinder is also provided at the inner end of the fixing support 5. The mica cylinder is in butt joint with the fixing support 5 and is installed outside the heating wire support 8, further enhancing the heat insulation protection and avoiding the high temperature conduction of the heating wire 7 to the distance measuring assembly. As a good insulating material, the installation of the mica cylinder makes the distance measuring system immune to the heat radiation interference from the heating components, ensuring the stability and reliability of the hair dryer distance measuring and temperature adjusting function.

[0032] In addition, a plurality of air outlets 3 are provided around the outer periphery of the fixing support 5, ensuring that the airflow can flow uniformly along the outside of the heat insulation cavity 11, thereby guiding and discharging the heat generated by the heating wire 7. The uniform distribution of the air outlets 3 enables the airflow to effectively cool the heating wire support 8, thereby controlling the overall temperature of the hair dryer and further improving the user's experience and safety.

[0033] The utility model discloses an intelligent temperature-regulating hair dryer structure with an independent heat-insulating cavity 11, which is formed by the surrounding arrangement of the heating wire support 8, the PCBA board 6 and the distance measuring plate 9, effectively isolates the distance measuring component from the heat source, prevents the high temperature from interfering with the normal operation of the distance measuring inductive IC 10, and simplifies the combination mode of the components, so that the hair dryer is more compact and portable as a whole, thereby improving the user experience and realizing the effect of accurate and constant temperature hair care.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any change or replacement without creative labor should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be limited by the protection scope defined in the claims.
