[0001] This utility model belongs to the field of hair straightener technology, specifically a multi-functional hot air hair straightener. Background Technology

[0002] Hair straighteners are one of the most common tools for styling hair in modern life. There are many hair styling tools available now, with a wide range of functions, such as infrared care and negative ion care. However, these functions are not integrated into hair straighteners. In other words, if users want to use infrared care or negative ion care, they need to purchase other products separately, which is inconvenient. Utility Model Content

At least one of the heat dissipation holes is provided with a negative ion generating end. The air outlets and heat dissipation holes are both located on the same side of the first heating plate assembly.

[0009] In a further technical solution, the control module independently controls the first heating plate assembly, the second heating plate assembly, and the airflow generating assembly. The illumination assembly can emit light including visible red light and invisible infrared light. The visible light is always on. Preferably, the wavelength of the visible red light is 650nm and the wavelength of the invisible infrared light is 850nm.

[0010] In a further technical solution, a Hall sensor is provided in the first clamping arm, which is electrically connected to the control module. A second magnet is provided in the second clamping arm to cooperate with the Hall sensor, thereby sensing and determining the opening and closing state of the first and second clamping arms and controlling the wind speed of the airflow generating component.

[0011] In a further technical solution, the airflow generating component is installed inside the first clamping arm and outputs airflow to the air outlet;

[0012] The light-emitting component is mounted on the second clamping arm, extends along the length of the second heating plate component, and is positioned vertically opposite to the positions of several air outlets.

[0013] A further technical solution is that the width of the portion of the first heating plate assembly exposed above the first clamping arm is B, the surface width of the first clamping arm used to install the first heating plate assembly is C, and the width from the air outlet to the edge of the first clamping arm is A, satisfying C>B>A, and preferably, A≤B / 2.

[0014] In a further technical solution, the first clamping arm includes an inner shell and an outer shell, with two wiring channels respectively located between the two. The two wiring channels are located on both sides and are used for wiring of the ion generating end and the first hot plate assembly, respectively. The wiring channel end corresponding to the ion generating end is provided with a forward-inclined ramp.

[0015] In a further technical solution, the illumination component includes a circuit fixing plate, the circuit fixing plate is provided with a plurality of red light infrared modules, and a transparent sealing colloid is fitted on the circuit fixing plate and the plurality of red light infrared modules.

[0016] A further technical solution is provided in the transparent sealing colloid, which has several mounting positions, each mounting position corresponding to two or one red infrared modules, and a clearance position is provided between two mounting positions. The second clamping arm has several holes that correspond one-to-one with the mounting positions, and a reinforcing rib is provided between the holes. The reinforcing rib corresponds to the clearance position.

[0017] In a further technical solution, springs and locking structures are installed on the first and second clamping arms near the rotating connection.

[0018] The locking structure includes a locking block disposed on the first clamping arm and a lever block movably disposed on the second clamping arm. The lever block has a locking hook at its bottom, which can extend into the first clamping arm and engage with the locking block.

[0019] The lever has spring arms on both sides, and the ends of the spring arms have locking points. The second clamping arm has a fixing strip for each spring arm, and the fixing strip has several locking positions that cooperate with the locking points on the side near the spring arm.

[0020] A further technical solution is provided with an air inlet at the end of the first clamping arm and a fixing frame. The outer periphery of the air inlet is covered with an inner filter screen, and an outer mesh cover is fitted around the outer periphery of the inner filter screen.

The outer periphery of the limiting ring platform is provided with a limiting groove and a first magnet, which cooperate with the limiting block and the nail, respectively. The fixing frame limits the outer mesh cover to the end of the first clamping arm.

[0021] The beneficial effects of this utility model are:

[0022] When this utility model is in use, the airflow blows out from the side of the hair straightener and acts on the hair. At the same time, the light-emitting component and the negative ion generator are also activated. The hair straightener slides on the hair, and the emitted infrared light also moves with the hair and acts on the hair. Although the negative ion generator is on the outside, the negative ions are drawn into the airflow and act on the hair because the airflow on the exhaust side is larger, thus achieving a dual care effect.

[0023] In addition, users can turn on the airflow generating component and the heating plate component separately or simultaneously according to their preferences, and combine them with infrared care and negative ion care to achieve multi-functionality, heating plate mode and mixed mode for users to choose from. When the heating plate mode is used, the airflow generating component will not work. At this time, the hair straightener will not produce wind noise. Users may mistakenly think that the hair straightener is not working and are prone to burns. Therefore, this embodiment uses visible infrared light to keep it in a constantly on state to remind users that the hair straightener is in working state, so as to prevent accidental contact with the heating plate area and injury.

Detailed Implementation

[0036] 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.

[0037] Please refer to Figure 1-10 ;

[0038] The hair straightener described in this utility model integrates multiple functions for user convenience. Specifically, it includes a first clamping arm 1, a second clamping arm 2, an airflow generating component 3, and a control module 4 that are rotatably connected. Currently, hair straighteners on the market have single-arm or double-arm airflow methods. In this embodiment, the airflow method is not limited. Therefore, the airflow generating component 3 outputs airflow to at least one of the first clamping arm 1 and the second clamping arm 2. In addition, the airflow generating component 3 consists of a fan and a heating component. The fan draws in air from the outside, and the heating component heats the air before outputting it.

[0039] Furthermore, a first heating plate assembly 51 and a second heating plate assembly 52 are respectively provided at opposite positions on the first clamping arm 1 and the second clamping arm 2, and at least one of the first clamping arm 1 and the second clamping arm 2 is also provided with a light-illuminating component 6. Both the first heating plate assembly 51 and the second heating plate assembly 52 can be composed of a heating element, a floating element, and a heat-conducting plate. The heat-conducting plate can be an aluminum plate or a ceramic plate. The first heating plate assembly 51 and the second heating plate assembly 52 can be relatively close and clamped together. In the clamped state, the surface of the light-illuminating component 6 maintains a certain gap with the opposite first clamping arm 1 or second clamping arm 2. The first heating plate assembly 51, the second heating plate assembly 52, and the light-illuminating component 6 are used to clamp the product. In the clamping state, the components are parallel to each other and extend in a narrow shape along the longitudinal direction of the product. The first clamping arm 1 has a row of narrow air outlets 15 extending in the longitudinal direction of the product on the side near the first hot plate assembly 51, and a row of narrow heat dissipation holes 16 extending in the longitudinal direction of the product is located on the same side of the air outlets 15 on the outer surface of the first clamping arm 1. When the first clamping arm 1 and the second clamping arm 2 are closed, they together form a narrow exhaust position on one side of the two, and the heat dissipation holes 16 are as close as possible to the exhaust position. The heat dissipation holes 16 are provided with negative ion generating ends 7. The light-emitting assembly 6, the air outlets 15 and the heat dissipation holes 16 are all located on the same side, and when the product is clamped, the three are parallel to each other.

[0040] When in use, the first clamp arm 1 and the second clamp arm 2 are closed, and the first and second ironing plate assemblies 51 and 52 clamp the hair. The airflow generating assembly 3 draws in external airflow for heating, and the airflow blows out from the air outlet 15 of the hair straightener and acts on the hair. At the same time, the light irradiation assembly 6 and the negative ion generating end 7 are also activated. The first and second ironing plate assemblies 51 and 52 clamp and heat the hair and slide. At the same time, the infrared light emitted by the light irradiation assembly 6 will also follow the displacement and act on the hair. Although the negative ion generating end 7 is on the outside, the negative ions will be drawn into the airflow and act on the hair because the airflow on the exhaust side is larger. At the same time, the hair straightener, hot air, light, and ion are used to achieve a four-fold care effect.

[0041] In addition, the control module 4 in this embodiment can control the airflow generating component 3 and the heating plate component separately. When both the first heating plate component 51 and the second heating plate component 52 have heating elements, the control module 4 controls them synchronously. In addition, the light irradiation component 6 can emit two wavelengths, namely 650nm visible light and 850nm invisible light. The 650nm visible light mode and the negative ion generating end 7 are normally open, while the 850nm invisible light mode is activated according to the usage status.

[0042] One embodiment of the present invention relates to the lighting component 6, see below. Figure 9Specifically, it includes a circuit fixing plate 61, on which several red infrared modules 62 are provided. Each red infrared module 62 is designed with a 650nm red light lamp bead and an 850nm infrared lamp bead. A transparent sealing colloid 63 is fitted on the circuit fixing plate 61 and the several red infrared modules 62. The transparent sealing colloid 63 is provided with several mounting positions 64. Each mounting position 64 corresponds to one or two red infrared modules 62. A clearance position 65 is provided between two mounting positions 64. The second clamping arm 2 is provided with several holes 21 corresponding to the mounting positions 64. A reinforcing rib 22 is provided between the holes 21. The reinforcing rib 22 corresponds to the clearance position 65, which can make the mounting positions 64 embedded in the mounting positions 64 to improve sealing and waterproofing. When clamping hair, when the hair is wet, it is easy to squeeze out water. Therefore, the transparent sealing colloid 63 is a flexible colloid, which is more conducive to sealing and waterproofing.

[0043] Users can turn on the airflow generating component 3 and the heating plate component individually or simultaneously according to their preferences, and combine them with infrared care and negative ion care to achieve multi-functionality, heating plate mode, and mixed mode for users to choose from. In addition, when the heating plate mode is used, the airflow generating component 3 will not work. At this time, the hair straightener will not produce wind noise. Users may mistakenly think that the hair straightener is not working and are prone to burns. Therefore, this embodiment uses visible infrared light to keep it in a constantly on state to remind users that the hair straightener is in working state, so as to prevent accidental contact with the heating plate area and injury.

[0044] When the hair straightener is in use, with the first clamp arm 1 and the second clamp arm 2 in the closed state, it has multiple speed settings. When the airflow generating component 3 is turned on, it will not be turned off under normal use. Therefore, when the first clamp arm 1 and the second clamp arm 2 are opened and hair is put in again, the airflow generating component 3 will still work normally, generating a large airflow that will disturb the hair and cause inconvenience to the user. To address this, in this embodiment, a Hall sensor 81 is provided in the first clamp arm 1, which is electrically connected to the controller. A second magnet 82, which cooperates with the Hall sensor 81, is located in the second clamp arm 2. When the first clamp arm 1 and the second clamp arm 2 are in the open state, the second magnet 82 is separated from the Hall sensor 81. At this time, the airflow generating component 3 is in a low-speed state, reducing environmental noise and power consumption, making it easier for the user to use. After the first clamp arm 1 and the second clamp arm 2 are closed, the second magnet 82 approaches the Hall sensor 81, and the airflow generating component 3 resumes high-speed airflow drive for normal operation.

[0045] In this embodiment of the utility model, only the first clamping arm 1 can vent air, while the second clamping arm 2 only has an auxiliary clamping function. Therefore, the airflow generating component 3 is installed inside the first clamping arm 1 and outputs airflow to the air outlet 15 of the first clamping arm 1. In addition, the light irradiation component 6 is installed on the second clamping arm 2, extending along the length direction of the second heating plate component 52, and is arranged vertically opposite to the positions of several air outlets 15. The red light and infrared light emitted by the light irradiation component 6 correspond vertically to the air outlets 15, and the negative ion generating end 7 is also close to the air outlet side. This allows multiple functions to converge in a limited space, enhancing hair care.

[0046] In this embodiment of the utility model, reference is made to Figure 6 The first heating plate assembly 51 and the second heating plate assembly 52 are arranged vertically and vertically. Taking the first heating plate assembly 51 as an example, one side of the first heating plate assembly 51 is close to the side of the first clamping arm 1, and the other side is provided with an air outlet 15. The width of the part of the first heating plate assembly 51 exposed to the first clamping arm 1 is B, the surface width of the first clamping arm 1 is C, and the width from the air outlet 15 to the edge of the first clamping arm 1 is A, satisfying C>B>A. Preferably, A≤B / 2. When the heating plate assembly is started alone, the effective heating area of ​​the heating plate assembly can be guaranteed, avoiding affecting the effect.

[0047] In this embodiment of the present invention, the first clamping arm 1 includes an inner shell 11 and an outer shell 12, with two wiring grooves 13 respectively located between them. The two wiring grooves 13 are located on both sides and are used for wiring between the ion generating end and the first heating plate assembly 51. Since the heating plate assembly contains a heating element, and traditional wiring methods require the wiring to pass through the heating element, which would affect the lifespan of the wires, this new structure avoids passing through the inside of the heating element, protecting the wires. The two wires are separated and routed on both sides, reducing interference to the negative ion generating end 7 and ensuring the amount of negative ions generated. Further, referring to… Figure 3 , Figure 4 and Figure 10 The end of the wiring channel corresponding to the ion generating end is provided with a forward-sloping ramp 14, which not only ensures the length of the end hair bundle or needle tip of the negative ion generating end 7, but also avoids bending the hair bundle or needle tip. Compared with the vertical end channel, the ramp 14 reduces the overall outer diameter width of the product.

[0048] In addition, the structure of the second clamping arm 2 can refer to the specific implementation of the first clamping arm 1, and it is also provided with independent wiring for the second hot plate assembly 52.

[0049] In this embodiment of the utility model, reference is made to Figure 4 and Figure 5The first clamping arm 1 has an air inlet (not shown) at its end and a fixing bracket 1711. The air inlet is covered with an inner filter screen 172. The fixing bracket 1711 limits and fixes the inner filter screen 172 to the end of the first clamping arm 1. An outer mesh cover 1731 is fitted around the inner filter screen 172. The outer mesh cover 1731 has a limiting hole 1732, a nail 1733 and a limiting block 1734. The fixing bracket 1711 has a limiting ring platform 1712 that cooperates with the limiting hole 1732 for the power supply line to pass through. The limiting ring platform 1712 has a limiting groove 1713 and a first magnet 1714 on its outer periphery, which cooperate with the limiting block 1734 and the nail 1733 respectively. The magnetic fixing method makes disassembly more convenient. The design of the limiting groove 1713 and the limiting block 1734 can make the outer mesh cover 1731 quick to install and prevent loosening.

[0050] Among them, the iron nail 1733 is a threaded nail. The outer mesh cover 1731 has several threaded holes for connecting with the threaded nail. In order to strengthen the strength of the threaded hole, a reinforcing strip 1735 at a 90° angle is provided on the outer periphery of the threaded hole. It is screwed and fixed to the mounting hole on the mounting post 1736 on the outer mesh cover 1731 by thread. The mounting post 1736 extends outward away from the limiting hole 1732 and has two mutually perpendicular reinforcing strips 1735. This structure not only strengthens the structural strength of the outer mesh cover 1731, but also increases the versatility, low cost and quick and stable installation of the iron nail 1733.

[0051] In this embodiment of the utility model, reference is made to Figure 7 and Figure 8 A spring 23 and a locking structure are installed near the rotating connection of the first clamping arm 1 and the second clamping arm 2. A groove 838 for limiting the spring 23 is provided at the first clamping arm 1 and the second clamping arm 2. A guide groove 8392 is provided on the first clamping wall and a guide block 8391 is provided on the second clamping arm 2. When in the unlocked state, the first clamping arm 1 and the second clamping arm 2 are separated by the spring 23. When in the closed state, the first clamping arm 1 and the second clamping arm 2 are kept closed by the locking structure, which is convenient for tidying.

[0052] More specifically, the locking structure includes a locking block 831 mounted on the first clamping arm 1 and a lever block 832 movably mounted on the second clamping arm 2. The lever block 832 has a locking hook 833 at its bottom, which can extend into the first clamping arm 1 and engage with the locking block 831. The lever block 832 has spring arms 834 on both sides, and the ends of the spring arms 834 have locking points 835. The second clamping arm 2 has a fixing strip 836 corresponding to each spring arm 834. The fixing strip 836 has several locking positions 837 on the side near the spring arm 834 that cooperate with the locking points 835. The locking points 835 and locking positions 837 limit the position of the lever block 832 and provide locking force to prevent the lever block 832 from shifting and unlocking.

[0053] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
