Description

Technical Field

[0001] This utility model relates to the field of curling iron components and curling irons, and more particularly to a curling iron component and curling iron with uniform airflow. Background Technology

[0002] A curling iron is a common hair styling tool primarily used to create curls by heating the hair. Its core components typically include a heating element, a temperature controller, a casing, and a power cord. The working principle of a curling iron is to heat the hair to a certain temperature using the heating element, temporarily changing the hair's shape; after cooling, a permanent curl is achieved.

[0003] While curling irons excel at curling hair, they lack the function of drying hair. Here are the main reasons why existing curling iron components cannot achieve this function: the core function of a curling iron is to change the shape of hair through heat, so its design focuses on temperature control and even heating of the heating element. Existing curling iron components do not have built-in fans or airflow generation devices, failing to generate sufficient airflow to dry hair; furthermore, the structure of curling irons is typically a slender cylinder, focused on heating, with limited internal space to accommodate the fan and motor components required for a hair dryer.

[0004] While the idea of ​​combining a curling iron and a hair dryer is appealing, practical applications face challenges related to size, functional coordination, safety, and cost. These drawbacks could result in a bulky, expensive, and difficult-to-use device, ultimately impacting the user experience. For example, in terms of functional coordination, a curling iron needs to heat the hair evenly, while a hair dryer needs to dry the hair quickly with airflow. Combining the two could lead to issues in coordinating heating and airflow.

[0005] Chinese Patent Publication No. CN221265456U relates to the field of household appliance technology, and in particular to a hair dryer curling comb assembly with uniform airflow from both the upper and lower ends. This utility model adopts the following technical solution: a hair dryer curling comb assembly with uniform airflow from both the upper and lower ends, comprising a curling comb housing and air outlets and comb teeth disposed on the curling comb housing. An air guide column is disposed within the curling comb housing, and several air guide plates are disposed on the air guide column, with the space between adjacent air guide plates aligned with the air outlets on the curling comb housing. The beneficial effect of this utility model is that by setting an air guide column within the curling comb housing and utilizing the air guide plates on the air guide column to disperse and guide the air blown out from the hair dryer, the uniformity of the airflow from the air outlets on the upper and lower sides of the curling comb housing is improved, thus improving the hair drying and styling effect. Although the curling comb assembly of this patent can also achieve side airflow, the airflow is perpendicular to the curling comb, and the airflow strength is uncontrollable, which cannot adequately meet the needs of drying and curling hair during use. Utility Model Content

[0006] The technical problem this invention aims to solve is that the clamping mechanism of traditional curling irons and hair dryers cannot achieve coordinated heating and airflow, resulting in unsatisfactory drying and curling effects. To address the aforementioned deficiencies of the prior art, this invention provides a curling iron assembly and curling iron with uniform airflow.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A curling iron assembly with uniform airflow is constructed, including an airflow equalization component. The upper end of the airflow equalization component is connected to a top cover, and the lower end is connected to a connecting shaft. The curling iron assembly is connected to a hair dryer through the connecting shaft. An air inlet is provided in the middle of the connecting shaft. An air duct is provided in the airflow equalization component corresponding to the air inlet. An air outlet is provided on the side of the airflow equalization component. Air enters the air duct from the air inlet and is blown out from the air outlet, acting on the hair. The airflow equalization component is formed by splicing multiple sets of airflow equalization components, and the air outlet is located at the splicing point of the airflow equalization components.

[0009] Preferably, the flow equalization component has a retaining tooth on one side and an air outlet on the other side. The air outlet has an air outlet rib, which divides the air outlet into multiple groups of air outlet holes. The air in the air duct is discharged through the air outlet and acts on the hair.

[0010] Preferably, the air outlet ribs are connected by an air outlet support column, and the locking teeth engage with the air outlet ribs to make the two sets of fluid connections, and the connection is located at the air outlet, with the connected air outlet positioned above the air outlet support column.

[0011] Preferably, the outer surface of the flow equalization element is teardrop-shaped, and the air discharged from the air outlet flows along the outer surface of the flow equalization element to form a rotating air outlet.

[0012] Preferably, the flow equalization component has a guide rib position corresponding to the air outlet rib position, and the guide rib position is connected to the air outlet rib position.

[0013] Preferably, the air guide ribs are inclined or arc-shaped.

[0014] Preferably, the width of the air guide ribs increases sequentially, with the width of the air guide ribs closest to the air inlet being the smallest.

[0015] Preferably, the upper cover and the connecting shaft are provided with screw holes, the flow equalization component is provided with screw posts on both sides corresponding to the screw holes, the upper cover is provided with protruding posts on the outer side, and the connecting shaft is provided with a groove corresponding to the flow equalization component, and the flow equalization component is placed in the groove.

[0016] Preferably, the connecting shaft has a mounting position on its side, and the flow equalization component is cylindrical or frustum-shaped.

[0017] A curling iron is constructed, comprising a curling iron body, wherein a curling iron assembly with uniform airflow as described above is connected to the curling iron body.

[0018] The beneficial effects of this utility model are as follows: by setting multiple sets of air outlets on the axial side of the flow equalization component, the air is discharged through the side air outlets and acts on the hair, resulting in better curling and blow-drying effects. At the same time, each set of air outlets corresponds to the air guide ribs to guide the air to the air outlets, and the width of the air guide ribs increases sequentially to ensure that the air volume and air speed blown out by each set of air outlets are basically the same, so that all parts of the hair can be heated simultaneously, enhancing the curling effect and speed.

[0019] By cutting the air duct with guide ribs and directing the airflow through them, combined with the curved guide ribs, even and gentle hot air can be continuously blown out during the curling process. The synergistic effect with the heat of the curling barrel allows the hot air to penetrate between every strand of hair, ensuring that the hair wrapped inside and outside the curling barrel is heated evenly, avoiding hair damage caused by localized overheating. At the same time, it makes the curls more uniform and natural, improving the overall styling effect. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] A preferred embodiment of this utility model provides a curling iron assembly with uniform airflow; such as... Figures 1-2 and Figure 12 As shown, it includes a flow equalization component 20. The flow equalization component 20 has through holes on both the upper and lower sides, forming an air duct inside. The upper end of the flow equalization component 20 is provided with a top cover 10, and the lower end is provided with a connecting shaft 30. The top cover seals the through holes at the upper end of the flow equalization component. An air inlet is provided in the middle of the connecting shaft. Multiple sets of air outlets are provided around the flow equalization component. The air outlets are connected to the equipment through the connecting shaft. The equipment is used to change the airflow speed and enter the air duct through the air inlet, and then blow it out through the air outlet for operation. The equipment can be a hair dryer, hair dryer, curling iron, or other equipment that can form a fluid.

[0036] Specifically, such as Figure 2 and Figures 4-9As shown, the flow equalization component 20 is formed by interconnecting six sets of flow equalization plates 200. Each flow equalization plate has multiple sets of retaining teeth 204 on one side and air outlets 207 on the other side corresponding to these retaining teeth. Each air outlet has an air outlet rib 206 corresponding to each set of retaining teeth, dividing the air outlet into multiple independent air outlet holes 207. The retaining teeth of each set of flow equalization plates 200 can be inserted into the air outlet of another set of flow equalization components to achieve splicing of the two sets of flow equalization components. The splicing of the six sets of flow equalization components forms a cylindrical flow equalization component. Simultaneously, some of the air outlet holes are connected to the outer surface of the flow equalization component 203 after splicing. When air enters the air duct through the air inlet 304, it is blown out through the air outlet holes 207 and then flows along the outer surface under the action of the outer surface. The outer surface 203 can be designed in a teardrop streamline shape, and the air exiting through the air outlet holes 207 can form a rotating airflow. It should be noted that the flow equalization component is not limited to six groups; multiple groups can be set. Multiple groups of flow equalization components can be spliced ​​together to form a flow equalization assembly. The flow equalization assembly is not limited to a cylindrical shape; it can also be set to a frustum shape. However, when it is frustum shaped, the area on the side closer to the top cover should be smaller than the area on the side closer to the connecting shaft.

[0037] Furthermore, such as Figure 4 and Figures 7-8 As shown, the flow equalization component 200 also includes multiple sets of air guide ribs 205, which are arranged longitudinally along the flow equalization component. Each set of air guide ribs is connected to an air outlet rib 206, so that each set of air guide ribs 205 corresponds to a set of air outlets 207. To ensure that the airflow of each set of air outlets 207 is the same, the width of the air guide rib 205 closer to the air inlet is smaller, and the width of the air guide rib 205 farther from the air inlet is larger. That is, the width of the air guide rib 205 increases sequentially from the air inlet to the top cover. Since the spacing between each set of air guide ribs is the same, the width of the air guide ribs can be distributed in an arithmetic sequence, or the width of adjacent air guide ribs can be set according to the different distances between two sets of air guide ribs, which can also ensure that the airflow to each set of air outlets 207 is the same. This will not be explained in detail here. Since the airflow is greater closer to the air inlet, the air guide ribs further away from the air inlet need to be designed to be wider to accommodate the greater airflow. This can be achieved by increasing the width of the air guide ribs along the connecting shaft to the top cover.

[0038] Furthermore, such as Figure 8 As shown, to further improve the performance of the air inlet / outlet 207 in the air duct, the air guide ribs are inclined, meaning the distance between the end of the air guide rib near the retaining tooth and the air inlet is smaller than that near the air outlet 207. The air guide ribs are also inclined in a streamlined arc shape, which provides better air guiding effect. Meanwhile, the air distribution element can be set in a straight line or a twisted arc shape; the arc shape provides better air outlet effect than the straight line.

[0039] Furthermore, such as Figures 2-11As shown, to facilitate the installation of the air distribution component, the outlet rib 206 is connected via the outlet support column 208. The outlet support column contacts the retaining teeth to achieve the final embedding of the air distribution component 200. The air distribution component has an upper screw post 201 and a lower screw post 202 at both ends. The upper cover has an upper cover screw hole 101 corresponding to the upper screw post, and the connecting shaft 30 has a connecting shaft screw hole 302 corresponding to the lower screw post. The connecting shaft also has a groove corresponding to each set of air distribution components 200. After assembling the air distribution components, they are placed in the grooves and the housing is fixed with screws to complete the assembly of the air distribution component. The air distribution component is then connected to the equipment via the mounting position 301 for operation, and also facilitates disassembly. A cylindrical protrusion 101 is provided at the end of the upper cover for easy removal of the air distribution component and to improve its aesthetics.

[0040] When using, such as Figures 12-13 As shown, after the six flow equalization components 200 are inlaid end to end, the upper end is connected to the upper cover 10 with screws, and the lower end is snapped into the groove and connected to the connecting shaft with screws to complete the assembly of the air outlet component. It is connected to devices such as a hair dryer through the mounting position 301. The air blown by the hair dryer enters the air duct along the B1 direction through the air inlet 304. During its upward movement along the B2 direction within the air duct, it is evenly dispersed by the air guide ribs 205 on the flow equalization component 200, and guided along the arc direction of the air guide ribs to the air outlet 207 for discharge. Guided by the teardrop-shaped outer surface 203, it achieves rotating airflow. Because the air guide ribs 205 are arc-shaped, they can better guide the air in the air duct to move along the arc direction of the air guide ribs to the air outlet 207. Combined with the width of the air guide ribs, this ensures that the airflow volume and velocity of each air outlet 207 are approximately the same.

[0041] It should be understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
