Description

Technical Field

[0001] This utility model relates to the field of hair styling tools, specifically to a hair curler with dual-sided air outlets. Background Technology

[0002] In the hair styling industry, hair curlers are a commonly used tool that helps people create various fashionable hairstyles by heating and styling the hair. Traditional hair curlers usually use a single-sided airflow design, meaning that hot air can only be blown out from one side of the curler to heat and style the hair.

[0003] However, this type of single-sided airflow hair curler has several drawbacks. Firstly, because hot air can only blow from one side, the relative position of the curler and the hair needs constant adjustment to ensure even heating of all parts of the hair. This is cumbersome and prone to uneven heating, affecting the curling results. Secondly, single-sided airflow concentrates heat in one area, which can lead to localized overheating and damage, reduce curling efficiency, and increase the user's waiting time.

[0004] To address the aforementioned issues, those skilled in the art have conducted relevant research and improvements. However, current improvements still have certain shortcomings in terms of structural design, airflow distribution, and ease of use. Therefore, developing a hair curler that can achieve dual-sided airflow, uniform heating, and convenient operation is of significant practical importance. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a hair curler with dual-sided air outlet, which aims to solve the problems of uneven heating, cumbersome operation, low hair curling efficiency and potential hair damage caused by single-sided air outlet of existing hair curlers.

[0006] The technical solution of this utility model to solve its technical problem is: a hair curler with double-sided air outlet, comprising:

[0007] The main support has an inner cavity, and the main support is provided with a main air inlet and a main air outlet communicating with the inner cavity;

[0008] The upper clamping plate assembly is rotatably connected to the main support, and the upper clamping plate assembly has an upper air inlet and an upper air outlet;

[0009] The lower clamping plate assembly is rotatably or fixedly connected to the main support, and the lower clamping plate assembly has a lower air inlet and a lower air outlet;

[0010] A PCB board is disposed within the aforementioned cavity;

[0011] A control switch is disposed on the upper clamping plate assembly and / or the lower clamping plate assembly, and the control switch forms a control connection with the PCB board;

[0012] A fan blade motor is disposed in the inner cavity and electrically connected to the PCB board.

[0013] It also includes:

[0014] The flexible diversion hood has one hood inlet and two hood outlets. The hood inlet is connected to the two hood outlets through air guide branches. The hood inlet is connected to and communicates with the main body outlet. One hood outlet is connected to and communicates with the upper air inlet, and the other hood outlet is connected to and communicates with the lower air inlet.

[0015] In some preferred embodiments of this invention, there are two air guide branches, each corresponding to one of the two air outlets of the cover, and a branch gap space is formed between the two air guide branches. This design allows the two air guide branches to be relatively independent, reducing mutual interference and ensuring the stability of wind force distribution.

[0016] In some preferred embodiments of this invention, the main support has a support portion that extends into the branch gap space. The support portion supports the flexible diverter shroud, preventing it from deforming under wind force and ensuring its structural stability and air guiding performance.

[0017] In some preferred embodiments of this invention, the flexible air-diverting shroud has arc-shaped diverting ribs located at the junction of two air-guiding branches, and the air-guiding branches also have inwardly protruding guide ribs. The arc-shaped diverting ribs can guide the air to flow smoothly into the two air-guiding branches, reducing airflow resistance; the guide ribs can further optimize the airflow path in the air-guiding branches, improving air-guiding efficiency.

[0018] In some preferred embodiments of this utility model, the flexible diversion shroud is fitted with a first fixed bracket and several second fixed brackets;

[0019] The first fixed bracket is fixedly connected to the main bracket by the first fastener; the edge of the air inlet of the cover extends outward to form a first limiting edge, and the first fixed bracket can abut against the first limiting edge to form a limiting and anti-detachment fit;

[0020] The second fixed bracket is fixedly connected to the upper clamping plate assembly / lower clamping plate assembly by the second fastener; the edge of the air outlet of the cover extends outward to form a second limiting stop edge, and the second fixed bracket can abut against the second limiting stop edge to form a limiting and anti-detachment engagement.

[0021] In the above configuration, the first and second fixed supports effectively prevent the flexible diversion shroud from falling off during use.

[0022] In some preferred embodiments of this utility model, the upper clamping plate assembly includes an upper clamping plate housing, an upper heating plate mechanism and an upper air guiding mechanism disposed in the upper clamping plate housing, and the upper air inlet is connected to the upper air outlet through the upper air guiding mechanism.

[0023] The lower clamping plate assembly includes a lower clamping plate housing, a lower heating plate mechanism and a lower air guide mechanism disposed within the lower clamping plate housing, and the lower air inlet is connected to the lower air outlet through the lower air guide mechanism.

[0024] The upper hot plate mechanism is located directly above the lower hot plate mechanism, and both the upper and lower hot plate mechanisms are electrically connected to the PCB board.

[0025] Using the above scheme, the upper and lower hot ironing plate mechanisms generate heat under the control of the PCB board, and work together with the hot air blown out from the air outlet to heat and style the hair held between them. The upper and lower air guiding mechanisms guide air from the upper air inlet to the middle air outlet and from the lower air inlet to the lower air outlet, respectively.

[0026] In some preferred embodiments of this invention, a negative ion generator is further provided in the upper clamping plate assembly and / or the upper air guide mechanism. An exhaust port is provided in the upper clamping plate housing and / or the lower clamping plate housing. The negative ion generator is located at the exhaust port, and the exhaust port faces the upper air outlet and / or the lower air outlet. The negative ions generated by the negative ion generator can be discharged from the air outlet with the airflow, adhering to the hair and moisturizing it while reducing static electricity.

[0027] In some preferred embodiments of this utility model, the main support is provided with a slider, the slider is slidably disposed on the main support, and the slider has at least an unlock position and a locking position;

[0028] Both the upper clamping plate assembly and the lower clamping plate assembly are provided with locking hooks, and the slider is provided with a locking part;

[0029] The upper clamping plate assembly has at least an unfolded state and a closed state relative to the lower clamping plate assembly;

[0030] When the slider is in the locked position, the locking part and the locking hook part abut against each other and form a limiting locking engagement to restrict the movement of the upper clamping plate assembly relative to the lower clamping plate, thereby keeping the upper clamping plate assembly in a closed state relative to the lower clamping plate assembly.

[0031] When the slider is in the unlocked position, the locking part and the locking hook part are offset from each other and the limiting locking engagement is eliminated. The upper clamping plate assembly can move relative to the lower clamping plate, so that the upper clamping plate assembly can switch between the closed state and the open state relative to the lower clamping plate assembly.

[0032] In some preferred embodiments of this utility model, the upper clamping plate assembly is rotatably connected to the main support via a first rotating shaft, and the lower clamping plate assembly is rotatably connected to the main support via a second rotating shaft. The rotating shaft structure enables rotation, and this rotatable connection method makes the rotation of the upper and lower clamping plate assemblies more flexible and smooth.

[0033] In some preferred embodiments of this invention, the upper clamping plate assembly is further provided with a display component, which is electrically connected to the PCB board. For example, the display component can display the working status of the hair curler, such as temperature, air speed, and working mode, allowing users to easily monitor the status of the hair curler in real time.

[0034] The beneficial effects of this utility model are as follows:

[0035] 1. Dual-sided airflow: By setting up a flexible split air hood, air is directed to the upper and lower clamping plate components respectively, achieving dual-sided airflow. This allows the hair to be heated from both sides simultaneously, resulting in more even heating and improved perming effect.

[0036] 2. Convenient operation: The upper and lower clamping plate assemblies can rotate relative to each other, and a slider locking mechanism is provided, which makes it convenient for users to adjust the clamping plate angle and store the clamps, making operation more convenient.

[0038] IV. Stable Structure: The design of the first fixed bracket, the second fixed bracket, and the support section ensures the stability of the connection between the flexible air distribution shroud and other components, thus improving the service life of the hair curler.

[0039] V. Rich in features: A display component is set up to show the working status of the hair curler in real time, which makes it convenient for users to adjust according to their needs and improves the user experience. Attached Figure Description

[0057] Example 1

[0058] Reference Figures 1 to 13A dual-sided air-exit hair curler includes: a main support 1 having an inner cavity 11, and the main support 1 having a main air inlet 12 and a main air outlet 13 communicating with the inner cavity 11; an upper clamping plate assembly 2 rotatably connected to the main support 1, and the upper clamping plate assembly 2 having an upper air inlet 21 and an upper air outlet 22; a lower clamping plate assembly 3 rotatably or fixedly connected to the main support 1, and the lower clamping plate assembly 3 having a lower air inlet 31 and a lower air outlet 32; a PCB board 42 (preferably electrically connected to an external power source via a cable 8 to obtain electrical energy), which is disposed in the inner cavity 11; and a control switch 41 disposed on the upper clamping plate assembly 2 or the upper clamping plate assembly 3. The control switch 41 is connected to the PCB board 42 and the lower clamping plate assembly 3; the fan motor 43 is disposed in the inner cavity 11 and electrically connected to the PCB board 42; it also includes: a flexible diversion hood 5 (preferably made of high temperature resistant silicone, soft plastic or other materials), which has one hood air inlet 51 and two hood air outlets 52. The hood air inlet 51 is connected to the two hood air outlets 52 respectively through the air guide branch 53, and the hood air inlet 51 is connected to and connected to the main body air outlet 13. One hood air outlet 52 is connected to and connected to the upper air inlet 21, and the other hood air outlet 52 is connected to and connected to the lower air inlet 31.

[0059] It should be noted that the lower clamping plate assembly 3 and the main support 1 can be rotatably connected, so that both the upper clamping plate assembly 2 and the lower clamping plate assembly 3 can open relative to the main support 1 when unfolded; or, the lower clamping plate assembly 3 and the main support 1 can be fixedly connected, so that the upper clamping plate assembly 2 opens relative to the main support 1 (lower clamping plate assembly 3) when unfolded. The specific connection relationship is not limited here.

[0060] The above content is the basic structural scheme of this application. Its working principle is as follows: First, after the motor is started, air is drawn in through the main air inlet 12. The airflow is guided through the inner cavity 11 of the main support 1 to the main air outlet 13. Then, the airflow enters the flexible split fan cover 5 and is divided into two streams through the internal air guide branch 53, which are respectively delivered to the air inlets of the upper and lower clamping plates. Finally, the airflow is ejected from the air outlets of the upper and lower clamping plates (upper clamping plate assembly 2 and lower clamping plate assembly 3). With the heating function of the clamping plates (usually the clamping plates have built-in heating elements, which are not mentioned in the description but are a standard configuration), the hair is heated / blown on both sides simultaneously to complete the perming and shaping.

[0061] The advantages of the basic solution in this application are at least as follows: First, it achieves dual-sided airflow, which, compared to single-sided airflow curlers, improves shaping efficiency and uniformity, avoiding differences in results caused by uneven heating of the hair. Second, the flexible fan shroud solves the airflow problem when the upper clamping plate assembly 2 rotates, ensuring both structural flexibility (for easy hair clamping) and stable airflow delivery, reducing airflow blockage caused by mechanical movement. Third, it achieves an integrated design, using a single fan blade motor 43 in conjunction with the flexible split-flow fan shroud 5 to achieve dual-sided air supply, simplifying the internal structure, reducing the size and weight of the device, and improving portability.

[0062] Reference Figures 4-9 In some preferred embodiments of this utility model, there are two air guide branches 53, each corresponding to one of the two air outlets 52 of the cover, and a branch gap space 54 is formed between the two air guide branches 53. This design allows the two air guide branches 53 to be relatively independent, reducing mutual interference and ensuring the stability of wind force distribution.

[0063] Optionally, refer to Figure 4 The main support 1 has a support portion 14 that extends into the branch gap space 54. The support portion 14 is a structural component extending from the main support 1 (therefore made of a relatively rigid material), typically possessing a certain degree of rigidity, and its function is to provide physical support or limitation. Although the flexible diverter hood 5 can deform with the rotation of the clamping plate, its own material is relatively soft, and it may undergo excessive deformation under airflow pressure or external force, leading to blockage of the air guide branch 53 or uneven airflow distribution. The support portion 14 enhances the structural stability of the flexible diverter hood 5, ensuring that the internal air guide branch 53 remains unobstructed during operation (especially under high wind speed and large opening / closing angles), maintaining a stable airflow distribution ratio.

[0064] When airflow enters the flexible split-flow hood 5 from the air inlet 51, if it directly enters the junction of the two air guide branches 53, the different directions of the two airflows can easily cause them to collide, resulting in energy loss or uneven distribution (e.g., strong airflow on one side and weak airflow on the other). Preferably, refer to Figure 9 The flexible air hood 5 has an arc-shaped diversion rib 55 located at the junction of the two air guide branches 53. The arc-shaped diversion rib 55 smoothly diverts the airflow through its curved surface, naturally guiding the airflow to the two branches, reducing turbulence caused by opposing forces, and ensuring a more balanced airflow between the two streams, thereby guaranteeing consistent airflow / heat at the upper and lower clamp outlets. Furthermore, the air guide branches 53 also have inwardly protruding guide ribs 56. The guide ribs 56 function to streamline the airflow, reduce turbulence within the branches, and optimize airflow speed and pressure.

[0065] In the preferred installation structure embodiment of the flexible diversion shroud 5, refer to Figures 5-6 The flexible air hood 5 is fitted with a first fixed bracket 57 and several second fixed brackets 58. The first fixed bracket 57 is fixedly connected to the main support 1 via a first fastener. The edge of the air inlet 51 of the hood extends outward to form a first limiting baffle 511, and the first fixed bracket 57 can abut against the first limiting baffle 511 to form a limiting and anti-detachment engagement. The second fixed brackets 58 are fixedly connected to the upper clamping plate assembly 2 / lower clamping plate assembly 3 via second fasteners. The edge of the air outlet 52 of the hood extends outward to form a second limiting baffle 521, and the second fixed bracket 58 can abut against the second limiting baffle 521 to form a limiting and anti-detachment engagement. The advantages of the above installation structure are: First, the flexible air hood 5 needs to deform with the rotation of the clamping plate, but its connection with the main support 1 and the clamping plate assembly needs to be stable and reliable. The fixed brackets (first fixed bracket 57 and second fixed bracket 58) are rigidly connected by fasteners (the first and second fasteners are preferably common components such as screws), while the limiting baffles replace rigid clamping by abutting and limiting, which prevents the flexible diverter shroud 5 from slipping off without restricting its flexible deformation capability. Secondly, the first and second fixed brackets 58, through the combined action of the fasteners and the first and second limiting baffles 521, firmly lock the air inlet and outlet of the flexible diverter shroud 5 at the docking position, minimizing airflow leakage and ensuring that all the diverted airflow can enter the corresponding upper and lower clamping plate assemblies 3. Thirdly, the first and second fixed brackets 58 and the first and second limiting baffles 521 can disperse the force on the flexible diverter shroud 5, reduce local stress concentration, delay aging or tearing, and improve overall durability.

[0066] The specific structure of each clamping plate assembly is as follows: (Refer to...) Figures 10-11 The upper clamping plate assembly 2 includes an upper clamping plate housing 23, an upper heating plate mechanism 24 disposed within the upper clamping plate housing 23, and an upper air guide mechanism 25. The upper air inlet 21 is connected to the upper air outlet 22 through the upper air guide mechanism 25. (Refer to...) Figures 12-13The lower clamping plate assembly 3 includes a lower clamping plate housing 33, a lower heating plate mechanism 34 and a lower air guide mechanism 35 disposed within the lower clamping plate housing 33. The lower air inlet 31 is connected to the lower air outlet 32 ​​through the lower air guide mechanism 35. The upper heating plate mechanism 24 is located directly above the lower heating plate mechanism 34, and both the upper and lower heating plate mechanisms 24 are electrically connected to the PCB board 42. Using this scheme, the upper and lower heating plate mechanisms 24 generate heat under the control of the PCB board, and work together with the hot air blown from the air outlet to heat and style the hair clamped between them. The upper and lower air guide mechanisms 25 guide air from the upper air inlet 21 to the middle air outlet and from the lower air inlet 31 to the lower air outlet 32, respectively.

[0067] Optionally, refer to Figure 13 The upper clamping plate assembly 2 and / or the upper air guide mechanism 25 are also equipped with a negative ion generator 6. When the negative ions generated by the negative ion generator 6 act on the hair, they can neutralize the positive charge on the hair surface (when hair is dry or damaged, it is easy to accumulate positive charge, which leads to frizz and tangles), and at the same time, they have a certain moisturizing and smoothing effect.

[0068] Furthermore, referring to Figure 13 The upper clamping plate housing 23 and / or the lower clamping plate housing 33 are provided with an exhaust port 36. The negative ion generator 6 is located at the exhaust port 36, and the exhaust port 36 is oriented towards the upper air outlet 22 and / or the lower air outlet. Thus, the airflow emitted from the air outlet forms a directional airflow field, allowing the released negative ions to be directly carried by the airflow and diffuse more efficiently to the surface of the clamped hair, avoiding the low efficiency caused by irregular diffusion of negative ions.

[0069] To enhance security, this embodiment provides a locking scheme, specifically as follows: (Refer to...) Figures 1-2 , Figure 7The main support 1 is provided with a slider 15, which is slidably mounted on the main support 1, and the slider 15 has at least an unlocked position and a locked position; both the upper clamping plate assembly 2 and the lower clamping plate assembly 3 are provided with locking hook portions 151, and the slider 15 is provided with a locking portion 152; the upper clamping plate assembly 2 has at least an unfolded state and a closed state relative to the lower clamping plate assembly 3. The working principle of the locking scheme is as follows: Locked state: When the slider 15 is in the locked position, the locking portion 152 abuts against the locking hook portion 151 and forms a limiting locking engagement to restrict the movement of the upper clamping plate assembly 2 relative to the lower clamping plate, thereby keeping the upper clamping plate assembly 2 in a closed state relative to the lower clamping plate assembly 3. Unlocked State: When slider 15 is in the unlocked position, the locking part 152 and the locking hook part 151 are offset from each other and the limiting locking cooperation is eliminated. The upper clamping plate assembly 2 can move relative to the lower clamping plate, so that the upper clamping plate assembly 2 can switch between the closed state and the open state relative to the lower clamping plate assembly 3. The core value of the locking scheme is that: first, it prevents the clamping plate assembly from accidentally opening due to shaking when stored, reducing the space occupied, and protecting the surface of the clamping plate from collision damage; second, if it is necessary to temporarily fix the clamping force during operation (such as the hair setting stage), it can prevent the clamping plate assembly from accidentally opening due to external force (such as the reaction force of hair), ensuring the stability of the shaping effect; third, it improves safety, especially for clamping plate assemblies with heating function, the closed locking can reduce the risk of accidentally touching high-temperature components when idle.

[0070] Preferably, refer to Figure 2 , Figure 11 , Figure 13 The upper clamping plate assembly 2 is rotatably connected to the main support 1 via a first rotating shaft 26, and the lower clamping plate assembly 3 is rotatably connected to the main support 1 via a second rotating shaft 37. The rotating shaft structure enables rotation, making the rotation of the upper clamping plate assembly 2 and the lower clamping plate assembly 3 more flexible and smooth.

[0071] Reference Figures 1-2 In some preferred embodiments of this utility model, the upper clamping plate assembly 2 is further provided with a display component 7, which is electrically connected to the PCB board 42. For example, the display component 7 can display the working status of the hair curler, such as temperature, air speed, working mode, etc., so that users can understand the status of the hair curler in real time.

[0072] It is worth noting that the other technical solutions of this utility model are all existing technologies, and therefore will not be described in detail.

[0073] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the concept of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.

The dual-sided air outlet hair iron of claim 1, wherein: The main body support (1) is provided with a sliding block (15), the sliding block (15) is slidingly arranged on the main body support (1), and the sliding block (15) has at least an unlocking position and a locking position. The upper clamping plate assembly (2) and the lower clamping plate assembly (3) are provided with a locking hook portion (151), and the sliding block (15) is provided with a locking portion (152). The upper clamping plate assembly (2) has at least an unfolded state and a closed state relative to the lower clamping plate assembly (3). When the sliding block (15) is in the locking position, the locking portion (152) abuts against the locking hook portion (151) and forms a limiting locking cooperation, so as to limit the movement of the upper clamping plate assembly (2) relative to the lower clamping plate, thereby keeping the upper clamping plate assembly (2) in the closed state relative to the lower clamping plate assembly (3). When the sliding block (15) is in the unlocking position, the locking portion (152) and the locking hook portion (151) are staggered and the limiting locking cooperation is eliminated, so that the upper clamping plate assembly (2) can move relative to the lower clamping plate, thereby enabling the upper clamping plate assembly (2) to switch between the closed state and the unfolded state relative to the lower clamping plate assembly (3).
