Description

Technical Field

[0001] The invention relates to the technical field of blowing equipment, and in particular to a long honeycomb heating and blowing device. Background Art

[0002] Most existing hair dryers use heating wires for heating. The heating wires are usually relatively large and occupy a large volume of the hair dryer. When the heating wire heats the flowing air, a large amount of heated air will be emitted from around the heating wire, resulting in low heating efficiency; and the temperature of the outer shell near the heating wire of the hair dryer is too high, causing the problem of being hot to the touch.

[0003] In order to solve the above problem in the future, the existing technology also adopts PTC honeycomb heating element for heating. The low-speed motor drives the fan blades to rotate to generate flowing air.

[0058] In order to make those skilled in the art better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0059] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0060] See also Figures 1 to 4 The present invention provides a long honeycomb heating and blowing device, comprising: a shell 10, a honeycomb ceramic heater 20 and a digital fan 40, wherein the shell 10 is provided with a first air outlet 101H; the honeycomb ceramic heater 20 is a long strip structure, the honeycomb ceramic heater 20 is installed in the shell 10, and is located at the position of the first air outlet 101H; the digital fan 40 is installed in the shell 10, and the air outlet duct of the digital fan 40 is connected with the honeycomb ceramic heater 20, and the honeycomb ceramic heater 20 is used to heat the normal temperature air output by the digital fan 40 and output it to the outside through the first air outlet 101H.

[0061] like Figure 1 and Figure 2 As shown in FIG. 1 , the housing 10 is provided with a first long air outlet 101H, through which the hot air heated by the honeycomb ceramic heater 20 can be output to the outside.

[0062] The honeycomb ceramic heater 20 is a highly efficient heater with uniform heat distribution. The metal alloy with excellent thermal conductivity ensures uniform temperature of the hot surface and eliminates hot spots and cold spots of the equipment. In addition, the honeycomb ceramic heater 20 is relatively small in size. The normal temperature wind output by the digital fan 40 is heated by the honeycomb ceramic heater 20 and then output, which can greatly reduce the loss of heat energy and improve the efficiency of heat energy use, thereby saving electricity. And through the relative heat insulation characteristics of the honeycomb ceramic heater 20, the air outlet part of the shell 10 will not be too hot and cause hot hands.

[0063] The honeycomb ceramic heater 20 is a long strip structure. After the normal temperature wind output by the digital fan 40 is heated, it can be evenly output through the long strip air outlet to achieve a better air outlet effect. In one embodiment of the present invention, the first air outlet 101H can also be connected to accessories such as an air comb and an air nozzle. Among them, the hair can be combed with the air comb. With the flat air nozzle, the output wind force can be more concentrated, achieving a stronger air blowing effect.

[0064] See also Figure 2 and Figure 5 The long honeycomb heating and blowing device further includes: an air guide structure 30, which is arranged at the air outlet duct of the digital fan 40. The air guide structure 30 is provided with a plurality of air ducts to evenly distribute the normal temperature air output by the digital fan 40 through each air duct and then output it to the honeycomb ceramic heater 20. Figure 2 and Figure 5 As shown in , the honeycomb ceramic heater 20 is located on 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 evenly act on the honeycomb ceramic heater 20. If the air 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; it is impossible to achieve a uniform heating effect, and the heating efficiency is low. Therefore, in the embodiment of the present invention, through the multiple air ducts on the air guide structure 30, the normal temperature output by the digital fan 40 can be distributed relatively evenly, and then output to the honeycomb ceramic heater 20, so that the normal temperature wind can pass through the honeycomb ceramic heater 20 relatively evenly, so that all heating surfaces of the honeycomb ceramic heater 20 can heat the normal temperature wind, the heating efficiency is high, and the air outlet is more uniform.

[0065] See also Figures 3 to 5 The wind guide structure 30 includes: a first wind guide housing 301 and a second wind guide housing 302, wherein the first wind guide housing 301 is provided with one or more first wind guide blocks 3011;

[0066] The second air guide housing 302 is connected to the first air guide housing 301, and the second air guide housing 302 is provided with one or more second air guide blocks 3021; ​​two or more air ducts are formed between the first air guide housing 301, the second air guide housing 302, the first air guide block 3011 and the second air guide block 3021.

[0067] like Figures 3 to 5In the embodiment, the air guide structure 30 introduces the normal temperature air output by the digital fan 40 through the bottom opening, and evenly distributes it through each air duct before outputting it from one side of the air guide structure 30. A plurality of air guide blocks are arranged in the air guide housing 10 at set intervals, and each air guide block is a bending structure, so that the normal temperature air introduced from the bottom of the air guide block is converted in direction and then outputted from the side. Figure 5 As shown in the figure, three air outlet channels are formed between the first air guide housing 301, the second air guide housing 302, the first air guide block 3011 and the second air guide block 3021. The normal temperature air output by the digital fan 40 is evenly distributed through the bottom of the three air outlet channels, and then changes direction through the three air outlet channels respectively, and finally output from the air outlets of the air outlet channels respectively. The air outlet of the air outlet channel faces the honeycomb ceramic heater 20. In this way, relatively uniform normal temperature air can be output to the honeycomb ceramic heater 20 for heating.

[0068] See also Figures 2 to 5 The second air outlets of two or more air ducts are arranged in sequence; the air outlet surface formed by the second air outlets of two or more air ducts is adapted to the ventilation surface of the honeycomb ceramic heater 20. Figure 2 and Figure 5 As shown in the figure, the air outlets of the multiple air outlet channels are arranged in an up-down arrangement to form an integral second air outlet. Since the size of the second air outlet is the same as the wind receiving surface size of the honeycomb ceramic heater 20, relatively uniform normal temperature air can be output to the entire honeycomb ceramic heater 20 for heating, thereby improving the heating efficiency.
