Description

Technical Field

[0001] This utility model relates to electric heating hair styling equipment, specifically to a hot air comb. Background Technology

[0002] A hot air comb is a hair styling device that uses hot airflow to comb and style hair. Most existing hot air combs have the heating element that generates heat and the fan that generates airflow installed inside the handle. Because the heating element and the fan require a long and wide space, the handle is bulky, making it not only difficult to hold but also inconvenient to operate.

[0003] Although some hot air combs have moved the heating element and fan forward to the comb head, most existing hot air combs have front-end airflow that bounces back after touching the outer wall of the comb head. This results in uneven airflow throughout the comb, making the actual styling effect less than ideal. Utility Model Content

[0004] The purpose of this invention is to provide a hot air comb that solves the problems of existing hot air combs, such as large handles, uneven airflow, which lead to difficult operation and poor styling results.

[0005] To achieve the purpose of this utility model, a hot air comb is provided, including a comb head and a handle. The comb head is connected to the handle. The comb head is densely covered with comb teeth and air outlet holes along its circumference. An electric heating component and a fan are installed inside the comb head. The electric heating component includes a heating element and an air guide shroud. The air guide shroud has a structure with one end open and the other end closed. The air guide shroud is fitted over the heating element. The air guide shroud is provided with air dissipation holes and an air guide section. The air dissipation holes are arranged circumferentially on the air guide shroud. The air guide section is formed by the closed end of the air guide shroud being recessed inward. The open end of the air guide shroud is the air inlet. The air inlet of the air guide shroud is connected to the air outlet of the fan.

[0006] As can be seen from the above scheme, the heating element and fan of this utility model are both located inside the comb head. Only the connecting wires are housed inside the handle; there is no limitation on the outer diameter of the handle, allowing for a more user-friendly grip and more diverse design options. Simultaneously, the heating element is very close to the comb teeth, resulting in stronger air pressure and faster heating from the air outlet, leading to better hair drying. Furthermore, this utility model's hot air comb features an air guide shroud outside the heating element. The air guide shroud contains an air guide section. Air blown from the fan directs room temperature air to the heating element, where it becomes hot air. The upper end of the air guide section is not open; air is transmitted through the diffuser holes on the side of the air guide shroud. Air hitting the air guide section is bounced back and also transmitted through the diffuser holes on the side. Because the hot air is redistributed within the air guide section, and the diffuser holes are close to the air outlet, the redistributed hot air does not need to bounce back and is directly blown out of the air outlet, resulting in more even airflow.

[0007] A further design includes a heating element comprising a wire frame and a heating wire, with the heating wire wound around the wire frame. The wire frame has a notch at one end near the air guide and a fixing part at the other end for connecting and fixing a fan.

[0008] As can be seen from the above scheme, the hot wire is tightly wound on the wire frame, resulting in a simple structure while ensuring uniform heat distribution and efficient heat transfer. The notch design at one end of the wire frame provides space for the air guide, enhancing the airflow and making the overall structure more compact. The fixing part at the other end securely connects to the fan, providing stable airflow support for the hot air comb.

[0009] A further option is to use a cross-shaped sawtooth wire frame.

[0010] As can be seen from the above scheme, the serrated structure facilitates the winding of the heating wire, the cross structure is stable, and the fixed fan is secure.

[0011] A further option is to install a diffuser in the middle of the wire rack along its length, with the diffuser extending circumferentially along the wire rack and a gap between the edge of the diffuser and the air guide shroud.

[0012] As can be seen from the above scheme, the setting of the air diffuser further redistributes the hot air. The air diffuser is located in the middle of the wire frame, which can cause the air in the lower half to bounce off the lower air diffuser holes and the air diffuser holes in the circumference. There is a gap between the edge of the air diffuser and the air guide hood so that the air can enter the upper half. The hot air in the upper half is bounced off and distributed by the air guide, making the air distribution more uniform, thereby ensuring more uniform air output.

[0013] A further design includes an inner shell that is fitted over the air guide cover. A sealing baffle is provided at one end of the inner shell near the air guide section, and the inner shell is densely covered with air outlet grilles.

[0014] A further design includes an outer shell for the comb, which is fitted over the inner shell. The comb teeth and air vents are located on the outer shell, and the air vent grille holes are correspondingly set with the air vents.

[0015] As can be seen from the above design, the inner shell supports the outer shell and better secures the comb teeth. Simultaneously, the inner shell, especially the sealing baffle, provides excellent heat insulation, preventing hot air from damaging the outer shell and reducing the lifespan of the hot air comb. The air outlet grille holes correspond to the air outlet holes, ensuring stable airflow.

[0016] A further design includes an end cap, which is fixed to the side of the inner shell where a sealing baffle is located, and the end cap is connected to the outer shell.

[0017] As can be seen from the above scheme, the end cap makes the hot air comb look more beautiful, and the end cap is fixed to the inner shell and the outer shell, making the fixation more stable.

[0018] A further design is to have a cylindrical air guide shroud with an arc-shaped surface for the air guide section.

[0019] As can be seen from the above scheme, the cylindrical air guide and the arc-shaped air guide are conducive to more uniform air distribution.

[0020] A further solution is to have an air inlet on the handle, located at the end of the handle furthest from the comb.

[0021] As can be seen from the above scheme, an air duct is formed inside the handle to ensure the air intake.

[0022] A further design involves installing a power cord at the end of the handle furthest from the comb, and setting control buttons on the side wall of the handle.

[0023] As can be seen from the above scheme, the electrical connection between the power cord, control key, heating element and fan ensures the stable operation of the hot air comb. Attached Figure Description

The process for forming the cross shape of the wire frame 111 is a process well known to those skilled in the art, such as insertion.

[0034] Preferably, a heat insulation sheet (not shown in the figure) can be fitted over the heating element. The heat insulation sheet is located inside the air guide shroud 114 and will not affect the propagation of the air. The purpose of setting the heat insulation sheet is to prevent the air guide shroud from being damaged due to excessively high temperature of the heating element, thereby improving the service life of the hot air comb.

[0035] The fan 12 includes a fan blade section 121 and a motor. The fan blade section 121 is located on the side away from the air guide section 1142, and the fan blade section 121 is connected to the air guide cover 113. Preferably, the motor in this embodiment is a DC motor.

The air that hits the air guide section 1142 is bounced off the air guide section 1142 and is also transmitted out through the air diffuser 1141 on the side. Since the hot air is first redistributed within the air guide section 1142, and the air diffuser 1141 is close to the air outlet 142, the redistributed hot air does not need to bounce off and is directly blown out from the air outlet 142, making the blown air more uniform. The diffuser 113 further redistributes the hot air. Located in the middle of the wire frame 111, the diffuser 113 allows the air in the lower half to be rebounded and dispersed through the lower and circumferential diffuser holes 1141. A gap exists between the edge of the diffuser 11 and the air guide shroud 114, allowing air to enter the upper half. The hot air in the upper half is rebounded and distributed by the air guide 1142, making the air distribution more uniform and ensuring more even airflow. The inner shell 13 supports the outer shell 14 and better secures the comb teeth 141. Simultaneously, the inner shell 13, especially the sealing baffle 134, provides good heat insulation, preventing hot air from damaging the outer shell 14 and reducing the lifespan of the hot air comb. The air outlet grid holes 131 correspond to the air outlet holes 142, ensuring stable airflow. The end cap 15 enhances the appearance of the hot air comb and is securely fixed to the inner shell 13 and the outer shell 14.

[0041] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
