Description

[Technical field]

[0001] The present invention relates to the technical field of hair dryers, and in particular to a highly efficient heat generating module used in a hair dryer. [Background technology]

[0002] A hair dryer is a small personal care appliance that can dry hair quickly. It mainly has a guide fluid passage with an outlet and a heat generating module built into the guide fluid passage, so that the air flowing through the heat generating module is heated and then blown out of the outlet to hit the hair. Far infrared rays have strong permeability and radiation ability, and have a remarkable temperature control effect and resonance effect, so that they are easily absorbed by objects and converted into the internal energy of the object. When far infrared rays are absorbed into the human body, they resonate with the water molecules in the body, activate the activity of the water molecules, and strengthen the binding force between the water molecules, thereby activating biopolymers such as proteins and bringing the biological cells to the highest vibration energy level. Since the biological cells generate a resonance effect, the thermal energy generated by the far infrared rays is transmitted deep into the skin of the body, raising the deep temperature of the skin, and the generated heat is dissipated from the inside to the outside. Such a strong action expands the capillaries, promotes blood circulation, strengthens the metabolism between tissues, enhances the regenerative ability of tissues and the immunity of the living body, and adjusts abnormal mental excitement, thereby functioning for treatment and health care. If negative ions could be released during a haircut, they could neutralize static electricity, smooth out the scaly surface, and repair and condition the hair, providing hair care.

[0003] A ceramic heating element is disposed between the heating device and the air outlet of the hair dryer so that negative ions and far-infrared waves can be generated by the air blown out of the hair dryer, thereby providing physiotherapy and beauty effects to the hair. The ceramic heating element has an emissivity of typically more than 85% at room temperature (25°C to 150°C), has high light-to-thermal energy conversion efficiency, and can generate negative ions. In response to this, the inventors have proposed a new type of far-infrared hair dryer described in a Chinese invention patent with application publication number CN116114988A. A heating mechanism (heating module) is assembled by arranging an annular heat dissipation assembly, an annular heating element, a far-infrared ceramic coating, and a fixing bracket. The annular heating element generates heat by applying electricity to generate thermal energy, and the heat is transferred by the annular heat dissipation assembly. A far-infrared ceramic coating is applied to the outer surface of the annular heat dissipation assembly. The far-infrared ceramic coating is made by mixing far-infrared ceramic powder and high-temperature resistant adhesive, and is applied to the annular heat dissipation assembly. When the heating element is heated, the heat energy is dissipated by the annular heat dissipation assembly, so that the hair can be dried. In addition, by fully utilizing the dissipation of heat energy by the annular heat dissipation assembly, the temperature of the far-infrared ceramic coating can be set to a range of 25°C to 150°C, and negative ions and far-infrared rays can be generated. Furthermore, by providing a fixing bracket, the annular heat dissipation assembly can be wrapped around the annular chamber so that it floats in the air, and the compactness of the entire structure can be maximized, ensuring smooth air blowing, reducing noise by reducing air resistance, and providing users with a more compact and comfortable usability.

[0004] In such a heating module, the heating module is limited to a single tubular structure mainly due to the guide part installed in the hair dryer. When the guide part is removed, the space vacant after the guide part is removed needs to be filled with a heating module in order to achieve the purpose of uniform heat reception. The usual way is to increase the number of tubular structures and fit multiple tubular structures of different diameters together to achieve a uniform coverage. However, when multiple tubular structures of different diameters are fitted together, a certain dimensional deviation may occur, making it difficult to fit two adjacent tubular structures together or causing wobbling after fitting. For example, in the graphene heating core and hair dryer described in the Chinese invention patent with application publication number CN112890401, such a heating module mainly includes multiple tubular structures assembled and fitted together. When it is necessary to ensure the effect of heat conduction, the metal sheet, the outer heat dissipation device, the outer insulating layer, the graphene heating layer, the inner insulating layer, the substrate tube and the inner heat dissipation device need to be closely combined, so the difficulty of assembly is greatly increased. In addition, the outer heat dissipation device and the inner heat dissipation device are both surrounded by multiple continuous U-shaped curved plates, so the heat dissipation device has a complex structure and is difficult to process. Therefore, it is necessary to propose a new technical means to solve the above problems. Summary of the Invention [Problem to be solved by the invention]

[0019] The following clearly and completely describes the technical solutions in the embodiments of the present invention. It is clear that the described embodiments are only some of the embodiments of the present invention, not all of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments that a person skilled in the art can obtain without performing creative work fall within the scope of protection of the present invention.

[0020] 1 to 6, in an embodiment of the present invention, a high-efficiency heat generating module used in a hair dryer includes a housing 10, an insulating bracket 20 provided in the housing 10, and a heat generating element 30 fixedly attached to the insulating bracket 20, the heat generating element 30 includes a heat conductive portion and a heat generating portion, the heat conductive portion includes a heat dissipating inner cylinder 31, at least one layer of honeycomb-shaped heat dissipation plate 40 provided outside the heat dissipating inner cylinder 31 so as to surround the heat dissipating inner cylinder 31, and an outer heat dissipation plate 32 provided outside the outermost honeycomb-shaped heat dissipation plate 40 so as to surround the outermost honeycomb-shaped heat dissipation plate 40, and the heat generating portion includes a first heat generating film 33 provided so as to be sandwiched between the heat dissipating inner cylinder 31 and the honeycomb-shaped heat dissipation plate 40, and a second heat generating film 34 provided so as to be sandwiched between the outer heat dissipation plate 32 and the honeycomb-shaped heat dissipation plate 40, The first heat dissipation fins 35 are evenly arranged on both the inside of the heat dissipation inner cylinder 31 and the outside of the outer heat dissipation plate 32. Both joints of the outer heat dissipation plate 32 have locking edges 36. The outer heat dissipation plate 32 is closed and locked by the two locking edges 36, restricting the honeycomb-shaped heat dissipation plate 40 between the outer heat dissipation plate 32 and the heat dissipation inner cylinder 31. The honeycomb-shaped heat sink 40 includes a first heat sink 41 and a second heat sink 42 arranged at a distance from each other, and a second heat sink fin 43 is evenly arranged between the first heat sink 41 and the second heat sink 42. Both joints of the first heat sink 41 and the second heat sink 42 have a joining edge 44, and the first heat sink 41 and the second heat sink 42 are abutted and joined to each other by the joining edge 44 when closed.

[0021] In the above technical proposal, the combination of the heat dissipating inner cylinder 31 and the outer heat dissipating plate 32 structures allows an annular space to be formed between the heat dissipating inner cylinder 31 and the outer heat dissipating plate 32, which accommodates at least one layer of honeycomb-shaped heat dissipating plate 40. The honeycomb-shaped heat dissipating plate 40 is in the shape of two plates and has a second heat dissipating fin 43 on one surface. By providing two plates, i.e., the first heat dissipating plate 41 and the second heat dissipating plate 42 in a surrounding manner, the second heat dissipating fin 43 is provided between the first heat dissipating plate 41 and the second heat dissipating plate 42. In addition, the first heat dissipating plate 41 and the second heat dissipating plate 42 are restricted to each other in a closed state by abutting and joining, so that a multi-layer fin heat dissipating structure can be formed by the heat conducting part of the heating element 30. This structure is mainly made by assembling simple plate materials. The inner heat-dissipating cylinder 31, the honeycomb-shaped heat-dissipating plate 40, and the outer heat-dissipating plate 32 can all be manufactured by an aluminum extrusion process, and can achieve the design objectives of small diameter, long length, and large number of fins, and can significantly increase the surface area to dissipate heat sufficiently. In addition, the first heat-dissipating fin 35 and the second heat-dissipating fin are preferably air guide structures in their structural design, and as shown in Figures 5, 7, and 8, the heat-dissipating fins can be strip-shaped structures or multiple convex structures arranged in an array, and the convex structures can be arc-shaped structures that can generate a spiral effect, and can be configured according to actual circumstances.

[0022] The honeycomb-shaped heat sink 40 is sandwiched between the heat-generating inner tube 31 and the outer heat sink 32 by fully utilizing the combination of the structures of the honeycomb-shaped heat sink 40 and the heat-generating inner tube 31 and the outer heat sink 32, so that the heat-generating part having the heat-generating film structure is sandwiched between the honeycomb-shaped heat sink 40 and the outer heat sink 32, and between the honeycomb-shaped heat sink 40 and the heat-generating inner tube 31. When multiple layers of honeycomb-shaped heat sinks 40 are provided, a heat-generating film may be provided between two adjacent layers of honeycomb-shaped heat sinks 40. The honeycomb-shaped heat sink 40 utilizes a plate-like structure to fully contact with the heat-generating film, thereby realizing a design scheme of sufficient heat conduction and multi-layer heat conduction, and ensuring that the fluid receives heat uniformly.

[0023] 2 and 4, in the case where a honeycomb-shaped heat sink 40 is provided between the heat sink inner cylinder 31 and the outer heat sink 32, a gap is formed between the first heat sink 41 and the heat sink inner cylinder 31, the first heat generating film 33 is provided between the first heat sink 41 and the heat sink inner cylinder 31, a gap is formed between the second heat sink 42 and the outer heat sink 32, and the second heat generating film 34 is provided between the second heat sink 42 and the outer heat sink 32. In the combination based on the second heat sink fin 43, the second heat sink fin 43 is formed on both the first heat sink 41 and the second heat sink 42, and the second heat sink fins 43 of the first heat sink 41 and the second heat sink 42 are arranged alternately. By allowing the first heat sink 41 and the second heat sink 42 to be restricted from each other, relative movement is prevented. In addition, the structure of the second heat dissipating fins 43 is fully utilized, and the second heat dissipating fins located at the joints of both the first heat dissipating plate 41 and the second heat dissipating plate 42 form a joint edge 44. The first heat dissipating plate 41 is provided with two adjacent second heat dissipating fins 43, and the two second heat dissipating fins 43 form an arc-shaped wrapping structure 45 that wraps around the temperature sensor, making the overall structure compact without adding any other fixing parts.

[0024] 2 and 5, the two locking edges 36 are parallel to each other, and the two locking edges 36 are formed with locking holes 37, and the two locking edges 36 are connected to the screw members 38 through the locking holes 37, and the outer heat sink 32 is closed and locked by screwing the screw members 38 with the two locking edges 36. In design, the two locking edges 36 may be spaced apart, and the compactness of the structural combination of the heat sink inner cylinder 31, the outer heat sink 32, and the honeycomb-shaped heat sink 40 can be ensured by tightening the screw members 38.

[0025] A far-infrared coating (not shown) is provided on the surfaces of the heat-dissipating inner cylinder 31, the honeycomb-shaped heat-dissipating plate 40, and the outer heat-dissipating plate 32. This far-infrared coating generates far-infrared rays with strong transparency and radiation ability, which expand capillaries, promote blood circulation, strengthen the metabolism between tissues, enhance the regenerative ability of tissues and the immune system of the living body, and adjust abnormal mental excitement, thereby serving the purpose of treatment and health care. If negative ions can be released during haircutting, static electricity can be neutralized, the scaly surface layer can be flattened, and hair can be repaired and shaped, thereby achieving hair care.

[0026] The first heating film 33 and the second heating film 34 are both manufactured using a graphene material or a heating wire material. Among them, the heat generated by graphene is due to heat generated by friction between carbon atoms. Such frictional motion is an irregular motion also called Brownian motion. The method of generating heat by far infrared rays like graphene is a method of emitting light with a wavelength of 8 to 15 micrometers, which is essential for the survival of living things. This light, like sunlight, resonates when it hits the human body and is absorbed and converted by the body. Therefore, the far infrared rays emitted during the heat generation process of graphene are light that can be used for physical therapy that is beneficial to the human body. Therefore, in this embodiment, by suitably manufacturing the first heating film 33 and the second heating film 34 with a graphene material, a better haircut effect can be achieved.

[0027] Referring to FIG. 6, the insulating bracket 20 includes a fixed plate and two first support plates 21, the fixed plate includes an insertion plate 22 and two second support plates 23 arranged at intervals on both sides of the insertion plate 22, a transition portion 24 is formed between the lower ends of the insertion plate 22 and the second support plate 23, the insertion plate 22 and the second support plate 23 are integrally connected by the transition portion 24, the insertion plate 22 is inserted into the heat dissipating inner tube 31, the first support plate 21 and the second support plate 23 are all abutted between the outer heat dissipation plate 32 and the housing 10 and are perpendicular to each other, and the insertion plate 22, the first support plate 21 and the second support plate 23 are all inserted through the gaps formed between two adjacent first heat dissipating fins 35. By arranging the insertion plate 22, the first support plate 21 and the second support plate 23, the entire heating element 30 is restricted between the insertion plate 22 and the support plate, thereby ensuring the stability of the fixation of the heating element 30 and insulating and separating it from the housing 10.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the illustrative embodiments described above, and that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, in all respects, the embodiments are to be considered as illustrative and not limiting, and the scope of the present invention is limited not by the above description but by the appended claims, and all changes that come within the meaning and range of equivalents of the claims are intended to be embraced therein.
