Description

A curling iron Technical Field

[0001] This invention relates to the technical field of hair treatment equipment, and in particular to a curling iron. Background Technology

[0002] With the development of technology, various curling irons have appeared on the market, such as air curling irons. These use the Coanda effect, created by airflow passing over a curved surface, to attract and curl the hair. However, these curling irons use hot airflow to curl the hair, resulting in less than ideal curls at the roots. To address this shortcoming, air curling irons incorporate heating elements to improve the curling effect. These heated air curling irons are divided into two parts: the upper part is the heating element, which heats and curls the hair, while the lower part is the air element, which uses hot airflow to attract and curl the hair. However, this solution results in higher temperatures at the top, requiring the use of heat-resistant materials. Otherwise, using ordinary materials may cause phenomena such as slagging, shortening the product's lifespan, or necessitating the use of specific materials, thus increasing costs. Summary of the Invention

[0003] To address the aforementioned issues, this application provides a curling iron that connects the air assembly and heating assembly of the curling iron via a connector. The airflow from the air assembly dissipates heat from the connector, thereby reducing the heat of the heating assembly and resolving problems such as excessively high top temperature, increased costs due to temperature resistance requirements, and melting of plastic parts caused by the use of ordinary materials.

[0004] A curling iron includes a styling section and a hair dryer body connected to the styling section, wherein the styling section includes:

[0005] An air assembly is provided with an air inlet at its lower end and a first air outlet on its periphery. Airflow is discharged from the first air outlet in a tangential direction along the outer surface of the air assembly, so that the airflow discharged from the first air outlet will attract and wrap the hair near the air assembly around the outer surface of the curling iron.

[0006] A heating element is connected to the upper end of the air assembly and is used to assist the air assembly in heating and styling the hair it adsorbs at the upper end of the heating element.

[0007] A connector for connecting the heating element to the air assembly, the connector extending through the entire length of the heating element.

[0008] The advantages are that the air assembly and the heating assembly are connected by a connector that runs through the heating assembly and connects to the air assembly. This facilitates the dissipation of heat from the heating assembly to the air assembly, promoting heat dissipation, reducing the heat generated by the heating assembly, and evenly distributing heat across the molding section. This also means that even with ordinary materials, the product will virtually not experience glue melting, thus reducing costs, minimizing glue melting, preventing safety issues, improving user experience, and extending product lifespan. Furthermore, the connector's length-through-the-heat-assembly structure facilitates heat conduction, further enhancing the uniformity of heat distribution within the product.

[0009] Preferably, the connector is made of metal, and the length of the connector is greater than the length of the heating element.

[0010] The advantage is that the thermal conductivity and heat dissipation performance of metal materials are better than those of traditional injection molded parts, which can absorb the heat inside the heating component. In addition, the length of the connector is greater than the length of the heating component, which can reliably connect and fix the two while conducting the absorbed heat to the air component.

[0011] Preferably, the connector is a screw, and the outer surface of the connector includes a threaded portion and a non-threaded portion, wherein the height of the threaded portion is higher than the height of the non-threaded portion.

[0012] The advantage is that the height of the threaded part is higher than that of the unthreaded part, and more threads can increase the overall contact area, which is beneficial for heat conduction.

[0013] Preferably, the heating component includes:

[0014] A coiled rod, wherein the coiled rod has a cylindrical structure and a heating element mounting cavity is formed inside the coiled rod, and the connecting parts are symmetrically arranged on both radial sides of the heating element mounting cavity;

[0015] A heating element is disposed within the heating element mounting cavity and is used to heat the curling iron to heat and style the hair through the outer periphery of the curling iron.

[0016] A bottom cover is disposed at the first end of the coil rod for connection to the upper end of the air assembly. The bottom cover is provided with a first receiving cavity through which the connector passes.

[0017] Preferably, the air assembly includes a main support frame, the upper end of which is provided with a connecting post. The connecting post extends into the first receiving cavity and is interference-fitted therewith. The end of the connecting post near the heating component is provided with a second receiving hole. The connecting post and the second receiving hole cooperate to realize the connection between the main support frame and the heating component.

[0018] The advantage is that the connector passes through the first receiving cavity on the bottom cover and the second receiving hole on the connecting post, which helps to transfer the heat of the heating component to the air component and achieve a heat dissipation effect.

[0019] Preferably, the internal space of the main support is connected to the air inlet to receive airflow, and the second receiving hole penetrates the connecting column to connect it to the internal space, thereby enabling the connector to contact the airflow.

[0020] The advantage is that the second receiving hole penetrates the connecting post, allowing the connector to come into contact with the airflow, thereby accelerating heat dissipation at the bottom of the connector.

[0021] Preferably, the internal space of the main support is connected to the air inlet to receive airflow, and a through hole is provided on the connecting column, the through hole is connected to the internal space, and the through hole is connected to the second receiving hole, thereby realizing the contact between the connector and the airflow.

[0022] The advantage is that one end of the connecting post has a through hole, through which the airflow in the air assembly enters the second receiving hole, thereby accelerating the heat dissipation efficiency of the side of the connector.

[0023] Preferably, the main support also includes a cylindrical body with a hollowed-out periphery, the cylindrical body is provided with a plurality of second air outlets, the cylindrical body is located below the connecting column, the airflow is blown out from the second air outlets, and the first air outlet is connected to the second air outlets.

[0024] Preferably, the heating component further includes:

[0025] A top cover assembly is detachably disposed at the second end of the winding rod for sealing the winding rod; the second end is located away from the air assembly.

[0026] A heat insulation element is disposed between the upper cover assembly and the heating element mounting cavity. The heat insulation element has a third receiving hole, and the connector passes through the third receiving hole from top to bottom.

[0027] The advantage is that by placing a heat insulation sheet between the top cover assembly and the heating element mounting cavity, heat can be prevented from being transferred to the top cover assembly, causing it to overheat and resulting in discomfort.

[0028] Preferably, the number of connectors N ≥ 2.

[0029] The advantage is that it can further enhance heat dissipation efficiency and better secure the heat-generating components and air components. Attached Figure Description

[0042] As shown in Figures 1-8, a curling iron includes a styling section 100 and a hair dryer body connected to the styling section 100, wherein the styling section 100 includes:

[0043] Air assembly 1, the lower end of the air assembly 1 is provided with an air inlet 101, and the air assembly 1 is provided with a first air outlet 102 on the periphery of the air assembly 1. The airflow is discharged from the first air outlet 102 in a tangential direction along the outer surface of the air assembly 1, so that the airflow discharged from the first air outlet 102 will attract the hair near the air assembly 1 and wrap it around the outer surface of the curling iron.

[0044] Heating component 2 is connected to the upper end of air component 1 and is used to assist air component 1 in heating and styling the hair it adsorbs.

[0045] Connector 3 is used to connect the heating element 2 to the air element 1, and the connector 3 extends through the entire length of the heating element 2.

[0046] In this configuration, the air assembly 1 and the heating assembly 2 are connected by a connector 3. The connector 3 passes through the heating assembly 2 and connects to the air assembly 1, thereby dispersing the heat generated by the heating assembly 2 into the air assembly 1, achieving a heat dissipation effect, reducing the heat generated by the heating assembly, and evenly distributing the heat in the molding section. This ensures that even when using ordinary materials, the product will not experience melting or glue formation. This reduces costs while minimizing melting and preventing safety issues, improving user experience, and extending product lifespan. The connector extends through the entire length of the heating assembly, facilitating heat conduction and further enhancing the uniformity of heat distribution within the product.

[0047] Furthermore, as shown in Figure 2, the heating component 2 includes: a coil 5, the coil 5 having a cylindrical structure and a heating element mounting cavity 6 formed inside the coil 5, and the connecting member 3 being symmetrically arranged on both radial sides of the heating element mounting cavity 6;

[0048] A heating element (not shown in the figure) is disposed in the heating element mounting cavity 6 and is used to heat the curling iron 5 to heat and style the hair through the outer periphery of the curling iron 5.

[0049] The bottom cover 8 is disposed at the first end of the coil 5 and is used to connect to the upper end of the air assembly 1. The bottom cover 8 is provided with a first receiving cavity 801, through which the connecting member 3 passes.

[0050] Furthermore, as shown in Figures 2, 3, 6, 7, and 8, the bottom cover 8 and the heating element mounting cavity 6 are integrally formed. This arrangement simplifies the production process and reduces production costs.

[0051] Furthermore, as shown in Figures 2, 3, and 7, the connector 3 passes through the first receiving cavity 801 on the bottom cover 8, and the heating element mounting cavity 6 is provided with a heating element (not shown in the figure). The heating element mounting cavity 6 is open at one end connected to the bottom cover 8. This arrangement allows the heat of the heating element to be dispersed towards the end closer to the bottom cover 8.

[0052] As shown in Figures 2, 3, 4, and 8, the air assembly 1 includes a main support 9. The upper end of the main support 9 is provided with a connecting post 901. The connecting post 901 extends into the first receiving cavity 801 and is interference-fitted therewith. The end of the connecting post 901 near the heating component 2 is provided with a second receiving hole 9011. The connecting post 901 and the second receiving hole 9011 cooperate to realize the connection between the main support 9 and the heating component 2.

[0053] Furthermore, as shown in Figures 2-5, the internal space of the main support 9 is connected to the air inlet 101 to receive airflow, and the second receiving hole 9011 penetrates the connecting post 901 to connect it to the internal space 903, thereby enabling the connector 3 to contact the airflow.

[0054] In another embodiment, the internal space 903 of the main support 9 is connected to the air inlet 101 to receive airflow. A through hole 9012 is provided on the connecting column 901, which is connected to the internal space 903 and the second receiving hole 9011, thereby enabling the connector 3 to contact the airflow.

[0055] In another embodiment, the second receiving hole 9011 penetrates the connecting post 901, and the connecting post 901 is provided with a through hole 9012 penetrating the connecting post 901. The through hole 9012 communicates with the internal space 903 and the second receiving hole 9011.

[0056] With this configuration, the connecting post 901 is penetrated through the second receiving hole 9011 and / or communicated with the second receiving hole 9011 through the through hole 9012, allowing the connecting member 3 to come into contact with the airflow, thereby quickly removing heat and improving heat dissipation efficiency.

[0057] Furthermore, as shown in Figures 2-3, the number of connecting posts 901 is the same as the number of connecting members 3. The connecting member 3 passes through the first receiving cavity 801 of the bottom cover 8 and enters the second receiving hole 9011 on the connecting post 901, so that at least a part of the connecting member 3 is disposed in the connecting post 901.

[0058] Furthermore, as shown in Figures 2, 3, 4, and 8, the main support 9 also includes a cylindrical body 902 with a hollowed-out periphery. The cylindrical body 902 is provided with a plurality of second air outlets 9021. The cylindrical body 902 is located below the connecting column 901. The airflow is blown out from the second air outlets 9021. The first air outlet 102 is connected to the second air outlets 9021.

[0059] As shown in Figures 2 and 3, the connector 3 is made of metal, and the length of the connector is greater than the length of the heating component.

[0060] With this design, the thermal conductivity and heat dissipation performance of the metal material are better than those of traditional injection molded parts. It can absorb the heat inside the heating component, and the length of the connector is greater than the length of the heating component, so that the absorbed heat can be conducted to the air component.

[0061] Furthermore, the connector 3 is a screw, and the outer surface of the connector 3 includes a threaded portion 301 and a non-threaded portion 302. The height of the threaded portion 301 is higher than the height of the non-threaded portion 302. More threads make it easier to increase the overall contact area, which is beneficial for heat conduction. In this embodiment, the height of the threaded portion is 50mm, which is conducive to heat conduction.

[0062] As shown in Figures 1-3, the heating component 2 further includes:

[0063] The top cover assembly 10 is detachably disposed at the second end of the winding rod 5 for sealing the winding rod 5; the second end of the winding rod 5 is away from the air assembly.

[0064] A heat insulation component 11 is disposed between the upper cover assembly 10 and the heating element mounting cavity 6. The heat insulation component is provided with a third receiving hole 1101, and the connecting component 3 passes through the third receiving hole 1101 from top to bottom.

[0065] As shown in Figures 2-3, the number of connectors 3, N≥2, is arranged in this way to increase heat dissipation efficiency and better secure the two components. In this embodiment, the number of connectors is 2.

[0066] The present application has been described above with reference to preferred embodiments; however, these embodiments are merely exemplary and illustrative. Various substitutions and modifications can be made to the present application based on these embodiments, all of which fall within the protection scope of the present application.
