Description

[Technical field]

[0001] The present invention relates to the technical field of hair repair, especially to a new type of far infrared hair dryer. [Background technology]

[0002] A hair dryer is a small personal care appliance that can dry hair quickly. It can warm the exhaust air by heating it with a heating wire, so that hair can be dried more quickly, shortening the time to dry hair and making it more convenient for people's lives. Far-infrared rays have strong penetration and radiation power, so they have a remarkable temperature control effect and resonance effect, and are easily absorbed by objects and converted into the internal energy of objects. After being absorbed by the human body, the far-infrared rays resonate with the water molecules in the human body, activating the water molecules and strengthening the binding force between molecules, thereby activating biopolymers such as proteins, and making the living cells reach the highest vibration level. Because the living cells generate a resonance effect, the thermal energy of the far-infrared rays can be transmitted to the deep subcutaneous part of the human body, so that the deep subcutaneous temperature rises and the generated heat is released from the inside to the outside. Such an action strength can expand the capillaries, promote blood circulation, strengthen the metabolism between each tissue, improve the regeneration ability of tissues, improve the immune ability of the body, and adjust the abnormal excitement state of the mind, thereby fulfilling the role of medical and health care. During the hair repair process, if negative ions can be released, it can neutralize static electricity, flatten the expanded scaly surface layer, repair the hair and make it docile, thereby playing a role in protecting the hair.

[0003] In order to generate negative ions and far infrared rays from the exhaust of the dryer and bring physiotherapy and aesthetic effects to hair, a ceramic heating element is often installed between the heating mechanism and the exhaust port in the dryer. The ceramic heating element has an emissivity of generally more than 85% at room temperature (25°C to 150°C), has an efficient light-to-heat conversion efficiency, and can generate negative ions. However, conventional ceramic heating elements are mainly installed in front of the heating mechanism with a honeycomb structure, and the combination of the ceramic heating element and the heating mechanism makes the structure not compact, increasing the overall volume of the dryer, and the combination of the ceramic heating element and the heating mechanism makes the internal fluid passages complicated, which greatly hinders the exhaust and makes the dryer produce a large noise when used. In response to this, it is necessary to provide a new technical means to solve the above-mentioned existing problems. Summary of the Invention [Problem to be solved by the invention]
