DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-4A hair dryer heating element that facilitates heat conduction is shown, including a main wheel 2, a plurality of fixed plates 3 are arranged on the outer circumference of the main wheel 2, the middle parts of the plurality of fixed plates 3 are staggered and wrapped with staggered heating wires 1, the staggered heating wires 1 increase the heat transfer area by staggered arrangement, the outer walls of the plurality of fixed plates 3 and wrapping the staggered heating wires 1 are provided with heat insulation plates 4, and the back of the fixed plates 3 is provided with a fuse structure 6.

[0023] It should be noted that the electric heating wire of this design uses a staggered electric heating wire 1. The design of the upper and lower staggered positions can make the heat of the air blown evenly during use, and the hot blowing area is wider, which is not easy to cause the electric heating wire to be overheated and damaged. The heat insulation board 4 uses heat-resistant materials to provide heat insulation protection and prevent heat from being transferred to the shell to burn the hands.

[0024] Specifically, the middle part of the fixing plate 3 is set as a deeply staggered concave structure, and the offset heating wire 1 is continuously wound in the concave structure. The concave structure and both sides of the top of the fixing plate 3 are provided with serrated grooves, which are used to fix the offset heating wire 1.

[0025] It should be noted that the fixed plate 3 is designed to use heat-resistant material, and the concave design in the middle is an important design to help the staggered installation of the misplaced heating wire 1. A serrated notch is opened on the top of the fixed plate 3, and the serrated notch is more suitable for snapping. By utilizing the elastic nature of the heating wire, the heating wire is snapped between each fixed plate 3 to form an annular structure, which makes the blowing heating contact more uniform.

[0026] Specifically, the dislocated heating wire 1 includes: an outer ring heating wire 101, which is wound in a concave structure at the top of multiple fixed plates 3, an inner ring heating wire 102, which is wound in a concave structure in the middle of the fixed plates 3, and the insulation plate 4 is currently cylindrical, and the insulation plate 4 is used to surround and protect the dislocated heating wire 1.

[0027] It should be noted that the staggered heating wire 1 is divided into an outer ring heating wire 101 and an inner ring heating wire 102. The two heating wires are staggered to make the heating area wider. The staggered heating wire 1 is annularly wound, and multiple electric heating wires are wound to form a barrel shape. In order to protect the hair dryer for safe use, a heat insulation board 4 is designed to protect the hair dryer shell. The designed heat insulation board 4 uses high temperature and heat resistance to fully wrap the staggered heating wire 1 to protect the overall high temperature resistance.

[0028] Specifically, a plurality of honeycomb hole structures 501 are provided on the surface of the filter sleeve 5, and the honeycomb hole structures 501 are used for ventilation. The fuse structure 6 includes: a first fuse point 601 and a second fuse point 602, and the top of the first fuse point 601 is fixedly connected to the bottom of the second fuse point 602. The first fuse point 601 is arranged in the middle of one end of the back side of the fixing plate 3, and the second fuse point 602 is arranged on the side of one end of the back side of the fixing plate 3.

[0029] It should be noted that the designed hair dryer sleeve adopts honeycomb ceramics, and a plurality of honeycomb-shaped holes are presented on the surface. The offset heating wire 1 will generate electromagnetic wave radiation and other impurities that are harmful to the human body when it is energized and heated. The installed hair dryer sleeve can effectively isolate these impurities and radiation that are harmful to the human body, thereby protecting the human body, hair and scalp. The designed fuse point is connected to the vicinity of the heating wire and is interconnected with the circuit. When the current exceeds the specified value, the heat generated by itself will cause the fuse to melt, disconnecting the circuit to play a protective role. The setting of the first fuse point 601 and the second fuse point 602 as double fuse points is adopted to achieve the effect of double protection.

[0030] Working principle of this utility model:

[0031] The middle part of the designed fixing plate 3 is a concave structure, so that the electric heating wire can present a staggered structure after being wound around the fixing plate 3. The heating area of ​​the staggered electric heating wire is wider than that of the traditional electric heating type. The staggered heating will not cause heat accumulation and concentrated heating in one area, which can protect the hair and scalp when used. The heat insulation plate 4 blocks the heat on the surface of the staggered electric heating wire, so that the protective shell is not affected by high temperature. When the current exceeds the specified value, the fuse structure 6 uses the heat generated by itself to melt the fuse and disconnect the circuit to play a protective role. The first fuse point 601 and the second fuse point 602 are used for double protection. When the electric heating wire is heated, electromagnetic wave radiation will be generated, which will affect the human body. The front filter sleeve 5 uses honeycomb ceramics to effectively isolate various effects of the electric heating wire on the human body and block radiation.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
