[0058] For the person skilled in the art to better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the technical field to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0059] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive or alternative embodiments. It is expressly understood that the embodiments described herein are combinable with each other.

[0060] Referring to Figures 1 to 4 The present application provides a strip-shaped honeycomb heating hair dryer, comprising: a shell 10, a honeycomb ceramic heater 20 and a digital fan 40, the shell 10 is provided with a first air outlet 101H; the honeycomb ceramic heater 20 is a strip-shaped structure, the honeycomb ceramic heater 20 is installed and arranged in the shell 10, and is located at the position of the first air outlet 101H; the digital fan 40 is installed and arranged in the shell 10, the air outlet air duct of the digital fan 40 communicates with the honeycomb ceramic heater 20, and the honeycomb ceramic heater 20 is used for heating the normal temperature air output by the digital fan 40 and outputting externally through the first air outlet 101H.

[0061] As Figure 1 and Figure 2 shown, the shell 10 is provided with a strip-shaped first air outlet 101H, and the hot air heated by the honeycomb ceramic heater 20 can be output externally through the first air outlet 101H.

[0062] Among them, the honeycomb ceramic heater 20 is a kind of high-efficiency, heat distribution uniform heater, through the metal alloy with excellent thermal conductivity, ensure that the hot surface temperature is uniform, eliminate the hot spot and cold spot of the equipment. In addition, the volume of the honeycomb ceramic heater 20 is relatively small, and the normal temperature air output by the digital fan 40 is heated and output after passing through the honeycomb ceramic heater 20, which can greatly reduce the loss of heat energy and improve the use efficiency of heat energy, thereby saving electric energy. And through the relative heat insulation characteristics of the honeycomb ceramic heater 20, the hand-burning problem caused by the temperature of the air outlet head part of the shell 10 being too high will not appear.

[0063] The honeycomb ceramic heater 20 is in a long strip structure, and the normal temperature wind output by the digital fan 40 can be uniformly output through the long strip-shaped air outlet after being heated, so that a better air outlet effect is achieved.

[0064] Referring to Figure 2 and Figure 5 , the long strip honeycomb heating hair dryer further comprises a wind guide structure 30, the wind guide structure 30 is arranged at an air outlet air duct of the digital fan 40, and a plurality of air ducts are arranged in the wind guide structure 30, so that the normal temperature wind output by the digital fan 40 is uniformly distributed through the air ducts and then output to the honeycomb ceramic heater 20. Figure 2 and Figure 5 , the honeycomb ceramic heater 20 is located at one side of the air outlet direction of the digital fan 40. The normal temperature wind output by the digital fan 40 cannot directly and uniformly act on the honeycomb ceramic heater 20. If the wind guide structure 30 is not added, the normal temperature wind output by the digital fan 40 is directly output to the top position of the shell 10, and then the normal temperature wind is guided to the honeycomb ceramic heater 20 through the top position of the shell 10. In this way, the normal temperature wind is only concentrated at the upper part of the honeycomb ceramic heater 20; the uniform heating effect cannot be achieved, and the heating efficiency is low. Therefore, in the embodiment of the utility model, the normal temperature wind output by the digital fan 40 can be relatively uniformly distributed through the plurality of air ducts on the wind guide structure 30 and then output to the honeycomb ceramic heater 20, so that the normal temperature wind can pass through the honeycomb ceramic heater 20 relatively uniformly, and the entire heating surface of the honeycomb ceramic heater 20 can heat the normal temperature wind, the heating efficiency is high, and the air outlet is also more uniform.
