[0035] Please see Figures 1 to 5 One embodiment of this application provides a hair dryer 100, which includes a housing 10, wherein the housing 10 has an air guide cavity 11, wherein the air guide cavity 11 is capable of accommodating user hair, and the housing 10 has an inner wall forming the air guide cavity 11; at least a portion of the inner wall forms a heating part 111, which is used to heat the user hair in contact with the heating part 111.

[0036] In this embodiment, the housing 10 has an air guide cavity 11 that can dry the user's hair. At the same time, the user can insert the hair into the air guide cavity 11 so that the hair can directly contact the heating part 111, and the heating part 111 can heat and style the user's hair.

[0037] Specifically, the design of the air guide cavity 11 not only guides airflow but also directly accommodates the user's hair for drying and styling. The inner wall of the housing 10 forms the boundary of the air guide cavity 11, and at least a portion of the inner wall area is designed as a heating element 111, which can directly contact and heat the user's hair.

[0038] In this embodiment, the hair dryer 100 integrates multiple functions, including drying hair and heating and styling hair. In one example, when a user needs to dry their hair after washing it, the hair dryer 100 of this embodiment can be aimed directly at the user's hair, and the air guide cavity 11 can concentrate the airflow, improving drying efficiency. In another example, when a user needs to heat and style their hair, the user can place the desired styled section directly into the air guide cavity 11, allowing it to contact the heating element 111 for precise heating and styling.

[0039] Furthermore, in this embodiment, the temperature of the heating element 111 of the hair dryer 100 can be intelligently adjusted to avoid overheating and damaging the hair. Users can also adjust the temperature of the heating element 111 themselves to achieve rapid heating and shaping.

[0040] In this embodiment, the specific form of the heating element 111 is not limited to meet different needs. In one example, the heating element 111 can be a smooth inner wall of the housing 10. The design of the air duct allows hair inserted into the air guide cavity 11 to adhere to the heating element 111, thereby performing the function of heating and styling. In another example, the surface of the heating element 111 has an auxiliary comb structure. After the user inserts hair into the air guide cavity 11, the hair can be attached to the auxiliary comb structure while combing, making it easier to guide the hair into the air guide cavity 11 and distribute it evenly. The auxiliary comb structure can simultaneously contact and heat the user's hair, thereby performing the function of heating and styling.

[0041] In some embodiments, the heating element 111 can heat the airflow entering the air guide cavity 11, allowing the user to use the warm air heated by the heating element 111 for drying. Thus, the hair dryer 100 of this embodiment achieves multi-functional integration, enabling simultaneous completion of both drying and styling steps, improving efficiency.

[0042] Furthermore, anti-scalding design can be made in the remaining parts of the housing 10 excluding the heating part 111, and heat insulation material can be used in the areas where the heating part 111 is not heated.

[0043] In the hair dryer 100 of this application embodiment, the heating part 111 can achieve professional styling effects that are difficult to achieve with traditional hair dryers by direct contact heating, while reducing hair damage caused by direct hot air blowing.

[0044] In some embodiments, the hair dryer 100 includes a first heating element 20, which is disposed on the inner wall and forms a heating section 111. Thus, the first heating element 20 is disposed on the inner wall of the housing 10, and the first heating element 20 can realize the function of heating and styling the user's hair.

[0045] In some embodiments, the first heating element 20 is a thin-film heating element, wherein the curvature of the side of the thin-film heating element away from the housing 10 is consistent with the curvature of the air guide cavity 11. In this way, the thin-film heating element maintains the same curvature as the inner wall of the housing 10, preventing the user from being caught on the sharp corners after inserting hair into the air guide cavity 11, and making the inner wall curvature of the hair dryer 100 more uniform and aesthetically pleasing.

[0046] For example, the first heating element 20 can be a thin-film heating element, which has the characteristics of being able to adhere to the inner wall of the housing 10 and bend and deform. Therefore, by placing the thin-film heating element inside the air guide cavity 11 and changing its shape with the structure of the air guide cavity 11, the thin-film heating element can fit more closely to the user's hair.

[0047] In the embodiments of this application, the specific material of the thin-film heating element is not limited, in order to meet different needs. For example, the thin-film heating element can be a graphene heating film, etc.

[0048] Furthermore, in this embodiment, a heat-insulating protective layer (such as a ceramic coating, mica sheet, etc.) can be provided between the first heating element 20 and the housing 10 to ensure heat conduction efficiency and prevent burns caused by direct contact between other parts of the user and the high-temperature metal. In this way, the user can directly attach the hair that needs to be styled (such as bangs, hair ends, etc.) to the heating part 111, and achieve a more lasting styling effect by using contact heating, which is more precise than traditional hot air styling.

[0049] In some embodiments, the first heating element 20 is a replaceable heating module. Users can replace it with heating elements of different shapes (such as straight plate type, wave type) or different powers according to design requirements.

[0050] In some embodiments, the hair dryer 100 includes a second heating element 30, which is disposed inside the housing 10 and can supply heat to the heating section 111. The second heating element 30 is also used to heat the airflow flowing through it. Thus, the second heating element 30 is disposed inside the housing 10 and protected by the housing 10, while the second heating element 30 can heat the airflow flowing through it, thereby realizing the function of the hair dryer 100 blowing hot air.

[0051] In some embodiments, the second heating element 30 includes a heating wire and a heating frame (not shown in the figure), with the heating wire wound in a wavy shape around the heating frame. This wavy shape increases the contact area between the heating wire and the airflow for better heating. The heating frame supports the heating wire, preventing direct contact between the heating wire and the housing 10 and thus preventing damage to other components.

[0052] In this embodiment, the first heating element 20 and the second heating element 30 can be activated simultaneously to improve the drying effect on the hair, which helps to distribute the hot airflow more evenly and thus effectively avoids the problem of excessively high local temperatures.

[0053] In one embodiment, the hair dryer 100 has only a second heating element 30, which is disposed within the housing 10 and can supply heat to the heating section 111. The second heating element 30 also heats the airflow passing through it. In this embodiment, the second heating element 30 can simultaneously provide hot air drying and contact heating for hair styling.

[0054] In another embodiment, the hair dryer 100 may include a first heating element 20 and a second heating element 30. This design enables the hair dryer 100 to have a dual heating system, which can achieve precise styling through the first heating element 20 (contact heating) and provide traditional hot air function through the second heating element 30 (airflow heating), thus meeting different hair care and styling needs.

[0055] In some embodiments, the first heating element 20 and the second heating element 30 can complement each other's insufficient heat. Specifically, the second heating element 30 can heat the flowing air to achieve the function of blowing out hot air for drying, at which time the first heating element 20 can assist in heating the air; the first heating element 20 can supply heat to the heating part 111 to achieve the function of heat contact molding, at which time the second heating element 30 can assist in supplying heat to the heating part 111.

[0056] In this embodiment, the specific material of the second heating element 30 is not limited to meet different needs. For example, the second heating element 30 can be a heating module such as an electric heating wire or a ceramic heating element, installed inside the air duct to directly heat the passing air and provide stable hot air.

[0057] In some embodiments, the housing 10 forms a first air duct, and the second heating element 30 is disposed within the first air duct. Thus, the second heating element 30 can heat the airflow passing through the first air duct, allowing the user to dry their hair with warm air.

[0058] In some embodiments, the thickness of the heating element 111 is less than the thickness of the housing 10, and / or the thermal conductivity of the heating element 111 is higher than that of the housing 10. Thus, the second heating element 30, disposed within the housing 10, can heat the user's hair through the heating element 111.

[0059] In this embodiment, the hair dryer 100 may include only the second heating element 30. In this case, the second heating element 30 can both heat the airflow and heat the user's hair upon contact.

[0060] Specifically, the thickness of the heating part 111 is less than the thickness of the shell 10, or the thermal conductivity of the heating part 111 is higher than that of the shell 10. In this way, the heat from the second heating element 30 can be more easily conducted to the user's hair through the heating part 111, so that the heating part 111 has enough heat to heat and style the user's hair.

[0061] In one embodiment, the thickness of the heating element 111 is less than the thickness of the housing 10, while the materials of the heating element 111 and the housing 10 remain unchanged. In another embodiment, the thermal conductivity of the heating element 111 is higher than that of the housing 10, and the thickness of the heating element 111 is the same as that of the housing 10. In yet another embodiment, the thickness of the heating element 111 is less than the thickness of the housing 10, and the thermal conductivity of the heating element 111 is higher than that of the housing 10. This ensures that the heat from the second heating element 30 inside the housing 10 is better transferred to the heating element 111.

[0062] Furthermore, the hair dryer 100 may also include a heating frame outer frame 31, wherein the heating frame outer frame 31 and the housing 10 are fixed together by snaps to form an installation space for a second heating element 30 and an air outlet duct.

[0063] In some embodiments, the housing 10 includes a head 12, which includes an inner ring wall 121 and an outer ring wall 122. The inner ring wall 121 and the outer ring wall 122 are concentrically arranged and cylindrical. The inner ring wall 121 defines an air guide cavity 11, and a heating element 111 is disposed on the inner ring wall 121. Thus, the head 12 is cylindrical, and the inner ring wall 121 can define the air guide cavity 11, allowing the user to insert hair into the air guide cavity 11.

[0064] In some embodiments, the head 12 includes an opening 123, an inner ring wall 121 and an outer ring wall 122 are connected through the opening 123, and the opening 123 is positioned directly opposite the heating element 111. Thus, with the opening 123 directly opposite the heating element 111, the airflow generated by the hair dryer 100 can achieve a wall adhesion effect in the air guide cavity 11, thereby attracting the user's hair to the heating element 111 for better heating of the hair.

[0065] In some embodiments, the housing 10 includes a handle 13 formed on the outer annular wall 122, and a fan is formed inside the handle 13 to provide airflow to the head 12. Thus, the handle 13 and the head 12 together constitute the main structure of the hair dryer 100, making it convenient for users to hold the hair dryer 100 to dry and heat-shape their hair.

[0066] In some embodiments, the head unit 12 includes a first air outlet 124 and a second air outlet 125. The first air outlet 124 is disposed at the end of the head unit 12, and the second air outlet 125 is disposed on the inner ring wall 121. The heating element 111 is disposed between the first air outlet 124 and the second air outlet 125. Thus, the first air outlet 124 can correspond to the first air duct, that is, the fan exits from the first air outlet 124 after passing through the air guide and the second heating element 30; the second air outlet 125 can correspond to the second air duct, that is, the fan exits directly from the second air outlet 125 after passing through the air guide.

[0067] In some embodiments, the second air outlet 125 extends toward the inner annular wall 121 in the airflow direction of the air guide cavity 11. This causes the airflow from the second air outlet 125 to be angled relative to the inner wall of the air guide cavity 11. The airflow discharged from the second air outlet 125 can be synchronized with the airflow from the air guide cavity 11 to dry the user's hair.

[0068] In some embodiments, the inner annular wall 121 protrudes towards the airflow direction of the air guide cavity 11. Thus, the side of the airflow exiting from the second air outlet 125 that contacts the protruding curved surface of the inner annular wall 121 slows down due to viscosity, forming a localized low-pressure area; the other side of the protruding curved surface of the inner annular wall 121 maintains high speed, generating a pressure difference that forces the airflow to deflect towards the low-pressure side and "attach" to the surface. In this way, the second air outlet 125, in conjunction with the protruding area of ​​the inner annular wall 121, can generate an adhesion effect, allowing the user's hair to directly adhere to the heating element 111 to achieve a hair straightening effect.

[0069] In some embodiments, the blower 100 includes an air guide assembly 40 disposed within the housing 10, which guides the airflow generated by the blower to a first air outlet 124 and / or a second air outlet 125. Thus, the air guide assembly 40 can assist in changing the direction of the airflow, ensuring that the airflow generated by the blower can be blown out through the first air outlet 124 and the second air outlet 125.

[0070] In some embodiments, the housing 10 includes a duct outer shell and a rear cover connected together by snap-fit. The duct outer shell includes a groove limiting structure, and the rear cover is fixedly connected to the groove limiting structure by snap-fit. The rear cover, together with the air guide assembly 40, forms a second air duct, and a second air outlet 125 of the second air duct is formed on the duct outer shell. In this way, the duct outer shell and the rear cover can form a relatively sealed state for the head 12, ensuring that the airflow of the second air duct can be discharged through the second air outlet 125.

[0071] In some embodiments, the dual-airflow design of the first and second airflow channels allows some airflow to be heated by the second heating element 30 and then blown out, while the other part of the airflow bypasses the heating element to form cold air, thereby achieving the function of alternating hot and cold air and enhancing the durability of the shape.

[0072] Specifically, since the second air outlet 125 is located on the inner ring wall 121, the airflow discharged from the second air outlet 125 can be discharged through the air outlet of the air guide cavity 11. At this time, the airflow discharged from the second air outlet 125 can generate negative pressure in the air guide cavity 11, allowing the air inlet of the air guide cavity 11 to flow in and be controlled. In this way, the air inlet and air outlet of the air guide cavity 11 can form a third air duct, which, together with the first and second air ducts, can dry the user's hair.

[0073] In some embodiments, the air guide assembly 40 includes a first air guide 41 and a second air guide 42, wherein the first air guide 41 is fixed together with the outer frame 31 of the heating frame by a snap fastener. The second air guide 42 is placed in the outer frame of the air duct of the housing 10, and the outer frame of the air duct has a groove limiting structure, which can also achieve a better sealing effect.

[0074] In addition, the hair dryer 100 also includes a printed circuit board 50, which is fixed to the first air guide 41 by screws. The back cover of the housing 10 is fixed to the outer shell of the hair dryer by a snap fastener. At the same time, there is a groove limiting structure in the outer frame of the hair dryer, which can achieve a better sealing effect.

[0075] In this embodiment, the wall-attaching effect can be achieved through the reasonable design of the air outlet angle, gap, and outer dimensions of the rear cover and the second air guide 42 at this position. Then, the airflow discharged from the second air outlet 125 passes through the heating unit 111 to achieve heating. The user's hair adheres tightly to the heating unit 111 due to the wall-attaching effect of the airflow, and achieves a shaping effect due to the high temperature.

[0076] In addition, in this embodiment, the bottom of the handle 13 is provided with a handle air inlet 131, and an air duct is formed inside the handle 13 to connect the handle air inlet 131 and the air inlet of the head 12.
