OVER-TEMPERATURE PROTECTION STRUCTURE AND HAIR DRYING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/087710
Kind Code:
A1
Abstract:
Disclosed are an over-temperature protection structure and a hair drying device (10), relating to the technical field of handheld appliances. The over-temperature protection structure comprises a body portion (200), a heater (400) and a first over-temperature protection piece (500); the heater (400) comprises an inner layer (410) and a heating element (430); the inner layer (410) is located at the inner side of the heating element (430) and is used for supporting the heating element (430); and the first over-temperature protection piece (500) is arranged at the inner side of the heating element (430). When the temperature of the heater (400) is high, the heater (400) is disconnected with the power supply and stops working, thereby avoiding damage caused by overheat to the heater (400) and surrounding parts, and further protecting the whole hair drying device (10). In comparison to an over-temperature protection piece arranged at the exterior of the heater (400), the first over-temperature protection piece of the hair drying device (10) is arranged in the heater (400); in this way, the temperature standard of power cut for the over-temperature protection piece (500) is a temperature inside the heater (400), thereby intuitively reflecting the temperature of the heater (400) so as to improve the safety performance and usability of the hair drying device (10).
