Description

Technical Field

[0001] This utility model relates to the field of hair dryer nozzle design, and in particular to a two-way airflow curling iron. Background Technology

[0002] With the improvement of people's living standards and the further pursuit of beauty, hair styling tools such as curling irons and straighteners are increasingly widely used, becoming common hair styling aids in daily life. A curling iron is a handheld electronic product used to curl hair; its main components are a handle and a heated curling iron. Similarly, we also use hair dryers daily, which are mainly used for drying and styling hair to meet daily hair care needs. Most existing curling irons are unidirectional, requiring two curling irons to curl the left and right sides of the hair, making them very inconvenient to use.

[0003] To address this, the prior art (Announcement No.: CN219813416U, Announcement Date: 2023.10.13) discloses an adjustable bidirectional airflow automatic hair curling nozzle for hair dryers, which uses the swing of blades to switch the blowing direction. However, the structure of the swing blades is relatively complex, resulting in inconvenient assembly, high production costs, and the possibility of air leakage after multiple swings, leading to a short service life.

[0004] In the prior art (Announcement No.: CN117084491A, Announcement Date: 20232.11.21), an improved bidirectional air-blowing hair curling device is also disclosed. The air outlet is set on the outer cylinder. The air volume is blocked and guided by the rotation of the inner core and the partition plate and the guide plate, so that the air blows in a clockwise or counterclockwise direction. However, the outer cylinder of this design is a one-piece structure, which requires the internal rotating core to block the air outlet on one side. When the seal is damaged, it is difficult to replace, which leads to air leakage in the hair curler. Once air leakage occurs, it is difficult to repair. Generally, the entire hair curler needs to be replaced, which is costly. Utility Model Content

After the inner core is rotated, the first protrusions are installed in the first grooves in a corresponding gap fit.

[0014] Furthermore: the inner side of the baffle is formed with a second groove on the side of the first protrusion, and the side of the second groove of the air outlet is formed with a second protrusion. After the inner core is rotated, the second protrusions are installed in the second groove with a corresponding gap fit.

[0015] Furthermore, multiple first and second air vents are provided, and the diameters of the first and second air vents gradually decrease from front to back.

[0016] Furthermore, the inner diameter of the inner core is set to gradually decrease from front to back.

[0017] Furthermore: the inner side of the outer cylinder is formed with multiple snap-fit ​​edges, which are arranged one-to-one between the two air outlets of the coil. The outer side of the inner core is formed with multiple snap-fit ​​double grooves, which are arranged between the two baffles. After the inner core is rotated, the snap-fit ​​edges snap into one of the slots of the snap-fit ​​double grooves.

[0018] Furthermore, both sides of the snap-fit ​​edge and the outer cylinder are formed with rounded corners, and the cross-section of the snap-fit ​​double groove has a wavy structure. The snap-fit ​​edge is installed in one of the grooves of the wavy structure of the snap-fit ​​double groove by snap-fitting with the rounded corners.

[0019] Furthermore: the rear end of the outer cylinder is equipped with a toggle cover, the front side of the toggle cover is formed with at least two insertion posts, the rear end of the outer cylinder is formed with at least two insertion slots, and the insertion posts are installed in the insertion slots with a gap fit in a one-to-one correspondence.

[0038] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0039] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0040] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0041] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] like Figure 1-11 As shown, the bidirectional air-out curling iron of this utility model includes an outer cylinder 1 and an inner core 2. The inner core 2 is formed with a plurality of first air vents 3 and second air vents 4 arranged in a circular array. The outer cylinder 1 is sleeved and installed on the outside of the inner core 2. The outer cylinder 1 is formed with a plurality of curling air vents 5 arranged in a circular array.

[0044] A baffle 6 is provided inside the air outlet 5 of the coil. The inner side of the baffle 6 is detachably installed on the inner core 2. The baffle 6 is located between the first air outlet 3 and the second air outlet 4. After the inner core 2 is rotated, the baffle 6 blocks the first air outlet 3 or the second air outlet 4.

[0045] The principle is as follows: the external baffle 6 is used to block the first air vent 3 or the second air vent 4 on the inner core 2. When air leakage occurs, the corresponding baffle 6 can be removed and replaced or adjusted without replacing the entire curling iron. The outer tube 1 rotates relative to the inner core 2 to switch between blocking the first air vent 3 or the second air vent 4, realizing the method of switching between blocking and blowing air on one side. This allows the curling iron to blow air in both directions, eliminating the need for curling irons in two directions, making it more convenient to use.

[0046] Furthermore, the outer side of the baffle 6 is covered with a rubber-coated component 7. After the inner core 2 is rotated, the rubber-coated component 7 of the baffle 6 blocks one side of the curling air outlet 5. The rubber-coated component 7 can be used to cover the outer side of the baffle 6, which can provide a better sealing effect for the baffle 6, allowing the baffle 6 to effectively block one side of the curling air outlet 5, thereby blocking the airflow from the first air outlet 3 or the second air outlet 4, achieving an effective wind-blocking effect. There will be no air leakage after switching the airflow direction. If air leakage occurs, the corresponding baffle 6 can be removed separately for repair or replacement.

[0047] Furthermore, the rubber-coated component 7 is made of rubber material; it has a certain degree of elasticity, a longer service life, and a better sealing effect, making it less prone to air leakage.

[0048] Furthermore, the inner side of the baffle 6 has a raised edge 8 formed in the middle, and the inner core 2 has a transverse groove 9 formed between the first air vent 3 and the second air vent 4. The raised edge 8 is fitted into the transverse groove 9 with a clearance fit, which makes the installation and positioning of the baffle 6 more accurate.

[0049] Furthermore: the two ends of the transverse groove 9 are respectively formed with snap grooves 10, and the two ends of the protruding edge 8 are respectively formed with buckles 11. The buckles 11 are fastened and installed in the snap grooves 10; the snap-fit ​​installation method can realize the rapid assembly of the baffle 6 on the inner core 2, thereby speeding up the production efficiency.

[0050] Furthermore: the inner side of the protruding edge 8 is formed with multiple positioning posts 12, and the transverse groove 9 of the inner core 2 is formed with multiple positioning holes 13. The positioning posts 12 are inserted into the positioning holes 13 in a one-to-one gap fit; this can ensure the stable assembly of the baffle 6 on the inner core 2.

[0051] Furthermore, multiple first protrusions 14 are integrally formed between the inner side of the baffle 6 and the convex edge 8, and multiple first grooves 15 are formed on both sides of the curling air outlet 5. After the inner core 2 is rotated, the first protrusions 14 are installed in the first grooves 15 with corresponding gaps. The structure of inserting the first protrusions 14 into the first grooves 15 can be used to prevent air leakage. Even without the rubber-coated part 7, it can effectively prevent leakage and ensure the service life of the curling iron.

[0052] Furthermore, the inner side of the baffle 6 has a second groove 16 formed on the side of the first protrusion 14, and the side of the second groove 16 of the curling air outlet 5 has a second protrusion 17 formed on the side. After the inner core 2 is rotated, the second protrusion 17 is installed in the second groove 16 with a corresponding gap fit. By using the structure of the first protrusion 14 inserted into the first groove 15 and the second protrusion 17 inserted into the second groove 16, the air leakage phenomenon of the curling iron after reversing can be effectively avoided, thus ensuring its service life.

[0053] Furthermore, multiple first air vents 3 and second air vents 4 are provided, and the apertures of the first air vents 3 and second air vents 4 gradually decrease from front to back; the inner diameter of the inner core 2 also gradually decreases from front to back; this can effectively control the airflow, allowing the air blown by the hair dryer to be controlled in the middle position between the entire inner core 2 and the outer tube 1, thereby achieving an effective curling effect.

[0054] Furthermore, the inner side of the outer cylinder 1 is formed with multiple snap-fit ​​edges 18, which are arranged one-to-one between the two air outlets 5. The outer side of the inner core 2 is formed with multiple snap-fit ​​double grooves 19, which are arranged between the two baffles 6. After the inner core 2 is rotated, the snap-fit ​​edges 18 snap into one of the grooves of the snap-fit ​​double grooves 19. This can achieve snap-fit ​​positioning after reversal, ensuring that it will not loosen on its own after reversal, and the air leakage prevention effect is better.

[0055] Furthermore: Both sides of the snap-fit ​​edge 18 and the outer cylinder 1 are formed with rounded corners 20, and the cross-section of the snap-fit ​​double groove 19 is a wave-shaped structure. The snap-fit ​​edge 18 is installed in one of the grooves of the wave-shaped structure of the snap-fit ​​double groove 19 by snap-fitting with the rounded corners 20; this allows the inner core 2 to rotate more smoothly and is convenient for reversing.

[0056] Furthermore: the rear end of the outer cylinder 1 is equipped with a toggle cover 21, the front side of the toggle cover 21 is formed with at least two insertion posts 22, the rear end of the outer cylinder 1 is formed with at least two insertion slots 23, and the insertion posts 22 are installed in the insertion slots 23 with a gap fit in a one-to-one correspondence; the toggle cover 21 can be used to drive the outer cylinder 1 to change direction, thereby facilitating actual use.

[0057] Furthermore, a toggle handle 24 is formed in the middle of the rear end of the toggle cover 21, which facilitates the rotation and reversal of the toggle cover 21 by twisting it.

[0058] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
