Description

Technical Field

[0001] This utility model relates to the field of hair curling iron technology, and in particular to a dual-heating hot air hair curling iron. Background Technology

[0002] A hair curling iron is a handheld electronic product used to curl hair, and it is very popular among women who love beauty. It is easy to operate and inexpensive, making it widely used. As people's living standards improve, hair curling irons, as everyday items, are hair styling tools for simple curling and styling, allowing for easy curling and styling. Currently, automatic hair curling irons are becoming increasingly popular. An automatic hair curling iron is an electronic product that automatically winds hair around a heating element.

[0003] Existing hot air curlers generate hot air through a heating element. This hot air is delivered into the hollow structure inside the hair shaft and then output through gaps in the shaft to curl the hair. Since the heating element is typically located inside the curler's handle, the hot air must pass through a hot air channel before reaching the hollow structure. To prevent the handle from becoming too hot and burning the user, or to avoid damaging the components within the channel with excessively hot air, the heating element cannot generate excessively hot air. Therefore, the temperature of the hot air directly output from the heating element to the hollow structure is relatively low, resulting in a less effective curl when the user's hair is stiff.

[0069] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0070] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the present invention.

[0071] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0072] See Figures 1 to 9This utility model provides a dual-heating hot air curling iron, including: a curling iron housing 10 and a curling iron main unit 20. The curling iron housing 10 is disposed outside the curling iron main unit 20. The curling iron main unit 20 includes a hair shaft 201 and a hot air device 202. The hair shaft 201 has a hollow structure and is provided with an air outlet 2011 communicating with the hollow structure. The hot air device 202 is used to generate hot air and deliver the hot air into the hollow structure of the hair shaft 201. A heater 2012 is also provided inside the hair shaft 201 for heating the hair shaft 201 and / or the hot air. The hot air is output through the air outlet 2011 and / or the hot air outlet 2011 to heat and shape the hair on the upper surface of the hair shaft 201. Specifically, as shown... Figure 2 As shown, during use, hair is rolled into the upper surface of the hair curler 201. The hot air device 202 generates hot air, which is delivered into the hollow structure inside the hair curler 201. Since the hot air device 202 is located away from the hair curler 201, and is typically located inside the handle of the curling iron, the hot air generated by the hot air device 202 needs to pass through a hot air channel before reaching the hollow structure of the hair curler 201. To avoid the handle of the curling iron becoming too hot and scalding, or to prevent excessively hot air from damaging the channels, the hot air device 202 cannot generate excessively hot air. Therefore, the temperature of the hot air output directly from the hot air device 202 into the hollow structure of the hair curler 201 will not be too high. When the user's hair is stiff, the styling effect is relatively poor. Therefore, this embodiment of the invention adds a heater 2012 inside the hair curler 201. The heater 2012 of the hair curler 201 can further heat the hot air output by the hot air device 202, achieving dual heating of the hot air. In this way, hot air can be heated to a higher temperature, thus outputting through the air outlet 2011 and / or the air outlet 2011. Simultaneously, the heater 2012 can also heat the air outlet 201, causing the surface temperature to rise rapidly. This allows the hair rolled into the surface of the air outlet 201 to be heated, thereby better curling and styling the hair. During use, the user can select different heating levels according to the softness or hardness of the hair to heat and style it. For example, as... Figure 2 As shown in the illustration, in one embodiment of this invention, four heating levels can be provided, and the curling iron housing 10 can be equipped with corresponding level buttons 1021, which can be used to select the heating level. Two of the heating levels are achieved by the hot air output generated by the hot air device 202 to heat and shape the hair. The other two heating levels can be achieved by the hot air device 202 and the heating element 2012 working together. In this way, four levels of hot air output at different temperatures can be generated to meet different application needs.

[0073] In some embodiments of this utility model, the upper surface of the heater 2012 is provided with an air duct recessed structure 2013 to guide hot air outward. The air duct recessed structure 2013 extends along the length direction of the hair shaft 201. This forms an air duct between the heater and the interior of the hair shaft 201, guiding the hot air to the air outlet 2011 or an air outlet gap. The air outlet 2011 can be of various shapes and sizes. To better heat and style the hair, the air outlets 2011 can be evenly distributed on the hair shaft 201. Similarly, the air outlet 2011 can be arranged along the length of the hair shaft 201, and multiple air outlets 2011 are provided. The air outlets 2011 are also relatively evenly arranged on the hair shaft 201. Like the air outlets 2011, the even arrangement allows for more uniform airflow after heating, thus enabling uniform heating of the hair curled on the surface of the hair shaft 201, thereby achieving a better curling and styling effect. The curling iron housing 10 is located outside the curling iron main unit 20, which surrounds and protects the outer surface of the hair shaft 201, preventing the hot air from burning the user's hands or other parts. The dual-heating hot air curler provided in this embodiment is disposed on the outside of the curling main unit 20 via a curler housing 10. The curling main unit 20 includes a hair shaft 201 and a hot air device 202. The hair shaft 201 has a hollow structure and is provided with an air outlet 2011 communicating with the hollow structure. The hot air device 202 generates hot air and delivers it into the hollow structure of the hair shaft 201, outputting it through the air outlet 2011 to heat and shape the hair on the upper surface of the hair shaft 201. Because the hot air is generated by the hot air device 202 and blown out from the evenly spaced gaps in the hair shaft 201 or the air outlet 2011, the hair on the surface of the hair shaft 201 can be heated. During the curling process, the hair is heated more evenly, thereby achieving a better styling effect.

[0074] See Figures 3 to 6 The hair curling machine 20 further includes: a curling pin 205 and a curling drive assembly 207. The curling pin 205 is located on the outer side of the hair shaft 201; the curling drive assembly 207 is used to drive the curling pin 205 to rotate, so as to curl the hair into the upper surface of the hair shaft 201. Figure 3As shown, the hair curler housing 10 has hair inlet slits 1011 on both sides. Hair can be placed from the root into the slit opening of the hair curler housing 10 through the hair inlet slits 1011. By controlling the hair curling drive assembly 207 to drive the hair curling cylinder 205 to rotate, the hair can be rolled into the upper surface of the hair tube 201. At the same time, hot air is output through the air outlet 2011 on the hair tube 201 to heat the hair rolled in the hair tube 201, thereby shaping the hair.

[0075] See Figure 7 and Figure 8 The hot air device 202 includes a heating wire 2021 and an air outlet 2022. The heating wire 2021 generates heat; the air outlet 2022 generates flowing air to transport the heat generated by the heating wire 2021 into the hollow structure of the hot air outlet 201. Figure 8 As shown, the heating wire 2021 can generate heat. Specifically, the heating wire 2021 can have multiple turns of heating wire, which can generate heat when energized. The heating wire 2021 can be arranged in a channel connected to the hollow structure of the hair shaft 201, with the hair shaft 201 located near one end of the heating wire 2021 and the air outlet 2022 located at the other end of the heating wire 2021. The air outlet 2022 generates flowing air and delivers it to the heating wire 2021, which heats the flowing air to generate hot air. The hot air is output through the air duct into the hollow structure of the hair shaft 201 and then output from the air outlet 2011 or the air outlet 2011.

[0076] See Figures 3 to 5 The hair curling machine 20 also includes a connector 203. The hair shaft 201 is connected to the hot air device 202 through the connector 203. The connector 203 has a hot air channel, and the hot air device 202 is interconnected with the hollow structure of the hair shaft 201 through the hot air channel. Thus, the hot air output by the hot air device 202 can be transmitted through the hot air channel in the connector 203 to the hollow structure of the hair shaft 201, and then output to the outside through a through hole or gap in the hair shaft 201. One end of the hair shaft 201 can be fixedly connected to the connector 203.

[0077] Among them, such as Figure 8As shown, the hot air device 202 further includes a heat-insulating air guide duct 2023 and a hot air device housing 2025. The heating wire 2021 is disposed inside the heat-insulating air guide duct 2023, the heat-insulating air guide duct 2023 is disposed inside the hot air device housing 2025, and the air outlet device 2022 is installed at one end of the hot air device housing 2025 and is fixedly connected to the other end of the connector 203 through the hot air device housing 2025.

[0078] like Figure 7 As shown, the connector 203 has a screw mounting hole near the end of the hot air device housing 2025, and the hot air device housing 2025 can be fixedly connected to the connector 203 by screws. The air outlet device 2022 may include a fan, which can be fixed to one end of the hot air device housing 2025 by screws. The airflow generated by the air outlet device 2022 can pass through the heat-insulating air guide 2023, be heated by the heating wire 2021 inside the heat-insulating air guide 2023, and then be output to the hollow structure of the hair shaft 201 through the connector 203. The heat-insulating air guide 2023 can achieve a certain heat insulation purpose, preventing the heat generated by the heating wire 2021 from being dissipated to the outside through the connector 203, thereby avoiding heat loss, and also preventing the curling iron housing 10 from getting hot near the connector.

[0079] See Figure 4 , Figure 5 and Figure 9 The hair curling drive assembly 207 includes a transmission assembly 2071 and a dial connector 2072. The transmission assembly 2071 includes a motor 20711 and a gear 20712. The motor 20711 drives the gear 20712 to rotate. The dial connector 2072 is disposed inside the connector 203. The inner side of the dial connector 2072 is provided with a transmission tooth 20721. The transmission tooth 20721 meshes with the gear 20712 to rotate under the drive of the gear 20712. The dial connector 2072 drives the hair curling dial 205 to rotate.

[0080] See Figures 7 to 9The hot air device 202 further includes: a motor heat insulation housing 2024. The heating wire 2021 has a ring-shaped structure, and the motor heat insulation housing 2024 is disposed within the heating wire 2021. The motor 20711 is installed within the motor heat insulation housing 2024. This allows for a tighter installation of the motor 20711, reducing the volume of the curling iron's handle. Additionally, the motor heat insulation housing 2024 provides some heat insulation, reducing the damage to the motor 20711 caused by the heat generated by the heating wire 2021, while also making the motor installation more compact and reducing the overall size of the curling iron. Figure 8 As shown, the gear 20712 may include a first gear 20712 and a second gear 20712. The first gear 20712 is mounted on the shaft of the motor 20711 and rotates with the second gear 20712. The second gear 20712 does not extend outward from the section of the motor heat insulation housing 2024. The dial connector 2072 is disposed inside the connector 203. Since the inner side of the dial connector 2072 is provided with a transmission tooth 20721, the transmission tooth 20721 can mesh with the second gear 20712. The motor 20711 can drive the gear 20712 to rotate. Through the meshing of the gear 20712 with the transmission tooth 20721 on the inner side of the dial connector 2072, the dial connector 2072 can be driven to rotate. The curling dial 205 is fixedly connected to the dial connector 2072. In this way, the curling pin 205 can be driven to rotate synchronously. The curling pin 205 is located on the upper surface of the hair shaft 201. After the hair is placed into the curling iron housing through the gap in the head section, the rotation of the curling pin 205 causes the hair to rotate, thus winding the hair around the upper surface of the hair shaft 201. The hot air output from the hair shaft 201 heats and styles the hair. The end of the hair shaft 201 can be fixed to the middle connecting end 2031 of the connector 203 with screws. A rotating connector 204 can be provided between the middle connecting end 2031 of the connector 203 and the pin connector 2072. This rotating connector 204 acts as a bearing between the rotating pin connector 2072 and the middle connecting end 2031 of the connector 203, reducing resistance to the rotation of the pin connector 2072 and allowing it to rotate more smoothly under the drive of the motor 20711. The generator 201 can also be connected to the dial connector 2072 via the generator connector 206.

[0081] Furthermore, according to one embodiment of this utility model, a heat insulation bracket 20241 is also provided on the outer side of the motor heat insulation housing 2024. The heating wire 2021 is installed on the heat insulation bracket 20241, and an air outlet channel is formed between the heat insulation bracket 20241 and the heat insulation air guide duct 2023. The air outlet channel is interconnected with the air outlet device 2022. In this way, by supporting the heating wire 2021 with the heat insulation bracket 20241, the contact area between the heating wire 2021 and the motor heat insulation housing 2024 can be reduced, and the heat of the heating wire 2021 can be reduced from being directly conducted to the heat insulation bracket 20241. At the same time, through the air outlet channel formed between the heat insulation bracket 20241 and the heat insulation air guide duct 2023, the room temperature air output from the air outlet channel is heated into hot air and then output to the hollow structure of the air outlet 201.

[0082] The motor heat insulation housing 2024 is also provided with a ventilation opening near the air outlet device 2022, and the ventilation opening is connected to the air outlet device 2022. The airflow introduced by the air outlet device 2022 through the ventilation opening can dissipate heat from the motor 20711 inside the motor heat insulation housing 2024, thus preventing the motor 20711 from overheating.

[0083] like Figure 8 and Figure 9 As shown, the heat insulation bracket 20241 may include multiple heat insulation sheets. Each heat insulation sheet can be fixed to the upper surface of the motor heat insulation housing 2024 by a fixing member. Each heat insulation sheet may be provided with serrations. The heating wire 2021 may be composed of multiple turns of metal wire, and each turn of metal wire may be fixed in a serrated groove, thus fixing the heating wire 2021. At the same time, multiple air outlet channels can be formed between the multiple heat insulation sheets and the heat insulation air duct 2023. The flowing air output by the air outlet device 2022 can pass through the air outlet channels and be heated by the heating wire to form hot air. The hot air reaches the hollow structure outlet of the generator 201 through the hot air channel provided in the connector 203, and is output through the through hole and / or gap to the outer surface of the generator 201.

[0084] Meanwhile, since the ventilation opening of the motor heat insulation housing 2024 is connected to the air outlet device 2022, the air outlet device 2022 can output to the motor heat insulation housing 2024 through the ventilation opening to dissipate heat from the motor 20711 inside the motor heat insulation housing 2024, thereby preventing the motor 20711 from overheating.

[0085] See Figure 2 and Figure 3The hair curling main unit 20 further includes: a control circuit board 208, on which control buttons 2081 are provided; the hot air device 202 and / or the heating element 2012 may also have a temperature sensor; the control circuit board 208 is electrically connected to the heating wire 2021, the temperature sensor, the motor 20711, and the air outlet device 2022 respectively, so as to control the heating wire 2021, the motor 20711, and the air outlet device 2022 according to the temperature detected by the temperature sensor. Figure 2 As shown, the control circuit board 208 may be equipped with multiple control buttons 2081 to adjust and control the working status of the heating wire 2021, the motor 20711, and the air outlet device 2022. The main housing may also be equipped with a gear selector button 1021, which controls the control buttons 2081 to switch gears. Furthermore, the hot air device 202 and / or the heater 2012 may also have temperature sensors to detect the temperature of the hot air generated by the hot air device 202 or the hot air output to the hollow structure of the air outlet 201. The control circuit board 208 can control the heating temperature of the heating wire 2021 or the heater 2012 via the control buttons 2081 to ensure that the output hot air temperature is within the set temperature range.

[0086] See Figure 2 and Figure 3 The curling iron housing 10 includes: a main unit housing 102 and a curling head housing 101. The hot air device 202, the transmission assembly 2071, and the control circuit board 208 are respectively located within the main unit housing 102. The curling head housing 101 is connected to the main unit housing 102, and the hair guide 201 and the curling pin 205 are respectively located within the curling head housing 101. Figure 2 and Figure 3 As shown, the dual-heating hot air curling iron may include a main unit and a curling head unit. The main unit may include a main unit housing 102 and a curling head housing 101, and includes a hot air device 202, a transmission assembly 2071, and a control circuit board 208, all of which are located within the main unit housing 102. The curling head unit may include a hair shaft 201 and a curling pin 205, both located within the curling head housing 101. A connector 203 serves as an intermediate connecting structure, connecting parts of the main unit and the curling head unit to form a single integrated structure.

[0087] See Figure 2 and Figure 3In one embodiment of this utility model, the end of the hair inlet 201 away from the hot air device 202 is also provided with a heat-insulating hair inlet nozzle 209, which is made of a non-thermal-conducting material. Since the heat-insulating hair inlet nozzle 209 is located at the hair inlet opening of the curling iron housing 10, it can prevent the heat from the hair inlet 201 from burning the hands or other parts during hair insertion.
