DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The technical solutions in the embodiments of the present disclosure are clearly and completely described below. Apparently, the described embodiments are merely some embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of present disclosure without making creative efforts shall fall within the protection scope of present disclosure.

[0033] Referring to FIG. 1 to FIG. 6, in the embodiments of the present disclosure, a high-efficiency heating module applied to a hair dryer includes a shell body 10 with two run-through ends, an insulation bracket 20 mounted in the shell body 10, and a heating main body 30 fixedly mounted on the insulation bracket 20, wherein the heating main body 30 includes a heat conduction portion and a heating portion; the heat conduction portion includes a heat radiation inner cylinder 31, at least one layer of honeycomb-shaped heat radiation plate 40 enclosed on an outer side of the heat radiation inner cylinder 31, and an outer heat radiation plate 32 enclosed outside the outermost layer of honeycomb-shaped heat radiation plate 40; the heating portion includes a first heating film 33 and a second heating film 34; the first heating film 33 is sandwiched between the heat radiation inner cylinder 31 and the honeycomb-shaped heat radiation plate 40, and the second heating film 34 is sandwiched between the outer heat radiation plate 32 and the honeycomb-shaped heat radiation plate 40; first heat radiation fins 35 are uniformly arranged on an inner side of the heat radiation inner cylinder 31 and an outer side of the outer heat radiation plate 32; two enclosed portions of the outer heat radiation plate 32 have locking edges 36; the outer heat radiation plate 32 is enclosed and locked by the two locking edges 36; the honeycomb-shaped heat radiation plate 40 is limited between the outer heat radiation plate 32 and the heat radiation inner cylinder 31;

[0034] each honeycomb-shaped heat radiation plate 40 includes a first heat radiation plate 41 and a second heat radiation plate 42 that are spaced apart from each other; second heat radiation fins 43 are uniformly arranged between the first heat radiation plate 41 and the second heat radiation plate 42; coupling edges 44 are arranged on two enclosed portions of the first heat radiation plate 41 and the second heat radiation plate 42; and after being enclosed, the first heat radiation plate 41 and the second heat radiation plate 42 resist against and are coupled with each other through the coupling edges 44.

[0035] In the above technical solution, by the structural cooperation between the heat radiation inner cylinder 31 and the outer heat radiation plate 32, an annular space can be formed between the heat radiation inner cylinder 31 and the outer heat radiation plate 32 to accommodate the at least one layer of honeycomb-shaped heat radiation plate 40. The honeycomb-shaped heat radiation plate 40 uses a two-plate structural setting provided with the second heat radiation fins 43 on one surface. By enclosing the two plates, namely by enclosing the first heat radiation plate 41 and the second heat radiation plate 42, the second heat radiation fins 43 are arranged between the first heat radiation plate 41 and the second heat radiation plate 42. Furthermore, the first heat radiation plate 41 and the second heat radiation plate 42 are mutually restrained after being enclosed, and the heat conduction portion of the heating main body 30 can form a multilayer finned heat radiation structure. This structure is mainly formed by assembling simple plates. The heat radiation inner cylinder 31, the honeycomb-shaped heat radiation plate 40, and the outer heat radiation plate 32 can all be manufactured through the aluminum extrusion process. Meanwhile, design purposes of small diameter, large length, and a large number of fins can be achieved; and the surface area can be greatly enlarged, thus fully radiating heat. Furthermore, the first heat radiation fins 35 and the second heat radiation fins 43 are preferably of air guide structures in structural design. As shown in FIG. 5, FIG. 7, and FIG. 8, the heat radiation fins may be of strip structures, or a plurality of arrayed bulge structures. The bulge structures may be cambered structures that can guide and generate a spiral effect. The heat radiation fins are set according to an actual situation.

[0036] By the full use of the structural cooperation between the honeycomb-shaped heat radiation plate 40 and the heat radiation inner cylinder 31, as well as the outer heat radiation plate 32, the heating portion is sandwiched. The heating portion uses a heating film structure, which is sandwiched between the honeycomb-shaped heat radiation plate 40 and the outer heat radiation plate 32, as well as between the honeycomb-shaped heat radiation plate 40 and the heat radiation inner cylinder 31. If there are a plurality of layers of the honeycomb-shaped heat radiation plates 40, a heating film can also be arranged between two adjacent layers of honeycomb-shaped heat radiation plates 40. The plate structure and the heating film are in full contact, so as to achieve a design mode of sufficient heat conduction and multilayer heat conduction, ensuring uniformity of fluid heating.

[0037] Referring to FIG. 2 and FIG. 4, one layer of honeycomb-shaped heat radiation plate 40 arranged between the heat radiation inner cylinder 31 and the outer heat radiation plate 32 is taken as an example. The first heat radiation plate 41 and the heat radiation inner cylinder 31 are in clearance fit; the first heating film 33 is arranged between the first heat radiation plate 41 and the heat radiation inner cylinder 31; the second heat radiation plate 42 and the outer heat radiation plate 32 are in clearance fit; and the second heating film 34 is arranged between the second heat radiation plate 42 and the outer heat radiation plate 32. Based on the cooperation of the second heat dissipation fins 43, the second heat radiation fins 43 are formed on both the first heat radiation plate 41 and the second heat radiation plate 42, and the heat dissipation fins on the first heat radiation plate 41 and the second heat radiation plate 42 are staggered from each other, so that the first heat radiation plate 41 and the second heat radiation plate 42 can be restrained each other to prevent sliding. In addition, by the full use of the structure of the second heat dissipation fins 43, the heat dissipation fins, located at the two enclosed portions, on the first heat radiation plate 41 and the second heat radiation plate 42 form the coupling edges 44. Two adjacent cooperative second heat radiation fins 43 are arranged on the first heat radiation plate 41, and the two second heat radiation fins 43 form an arc-shaped hoop structure 45 configured to wrap a temperature sensor, so that the overall structure is compact, and no parts for fixing will be added.

[0038] Referring to FIG. 2 and FIG. 5, the two locking edges 36 are parallel to each other; locking holes 37 are formed in the two locking edges 36; the two locking edges 36 are connected with bolt pieces 38 through the locking holes 37; and the outer heat radiation plate 32 is enclosed and locked by cooperation between the bolt pieces 38 and the two locking edges 36. According to the design, the two locking edges 36 can be spaced apart from each other. As the bolt pieces 38 are screwed up, the compactness of structural cooperation between the heat dissipation inner cylinder 31, the outer heat dissipation plate 32, and the honeycomb-shaped heat dissipation plate 40 can be ensured.

[0039] A layer of far infrared coating layer (not shown in the figure) is arranged on a surface of each of the heat radiation inner cylinder 31, the honeycomb-shaped heat radiation plate 40, and the outer heat radiation plate 32, is configured to generate far infrared rays, and has high penetrability and radiation power. Capillaries expand; the blood circulation is promoted; metabolism between tissues is enhanced; the regeneration ability of tissues is improved; body's immunity is improved; and the abnormal mental states are adjusted, thus playing a role in health care. If negative ions can be released in a hair cutting process, static electricity can be neutralized to flatten the open hair cuticles, and repair and smooth the hairs, thus playing a hair care role.

[0040] The first heating film 33 and the second heating film 34 are both made of a graphene material or a heating wire material. Graphene generates heat through friction between carbon atoms. This frictional motion is an irregular motion, also referred to as Brownian motion. The graphene, as a far infrared heating mode, releases a life light of 8 to 15 microns. This light is the same as the sun. After being in contact with the human body, the light can resonate and be absorbed and converted by the human body. Therefore, the far infrared rays released during the heating of the graphene is therapeutic light that is beneficial for the human body. Therefore, in this embodiment, the graphene material is preferably used to make the first heating film 33 and the second heating film 34, which can achieve a more efficient hair cutting effect.

[0041] Referring to FIG. 6, the insulation bracket 20 includes a fixed plate and two first supporting plates 21; the fixed plate includes an insertion plate 22 and two second supporting plates 23 spaced apart on two sides of the insertion plate 22; a transition portion 24 is formed between the insertion plate 22 and a lower end of the second supporting plate 23; the insertion plate 22 and the second supporting plate 23 are integrally connected through the transition portion 24; the insertion plate 22 is inserted into a center of the heat radiation inner cylinder 31; the first supporting plate 21 and the second supporting plate 23 both resist between the outer heat radiation plate 32 and the shell body 10; the first supporting plate 21 and the second supporting plate 23 correspond vertically to each other; and the insertion plate 22, the first supporting plate 21, and the second supporting plate 23 are all inserted through gaps reserved between two adjacent first heat radiation fins 35. By the arrangement of the insertion plate 22, the first supporting plate 21, and the second supporting plate 23, the entire heating main body 30 is restrained between the insertion plate 22 and the supporting plates, thereby ensuring the firmness of fixing of the heating main body 30 and insulating the heating main body from the shell body 10.

[0042] For those skilled in the art, it is apparent that the present disclosure is not limited to the details of the exemplary embodiments mentioned above, and can be implemented in other specific forms without departing from the spirit or basic features of the present disclosure. Therefore, in any perspective, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present disclosure is limited by the accompanying claims rather than the above description. Therefore, all changes within the meaning and scope of the equivalent conditions of the claims within the present disclosure.
