Description

Technical Field

[0001] This utility model belongs to the technical field of hair styling tools, specifically relating to the ionic structure of a hair styling tool. Background Technology

[0002] Hair styling tools, as common hair-styling equipment, are widely used in various hairstyle creation scenarios. However, as people's demands for hair styling results and hair care continue to increase, traditional hair styling tools are gradually becoming unable to meet these needs in terms of functionality and user experience. Among these challenges, heat dissipation has consistently been one of the key factors restricting the improvement of hair styling tool performance.

[0003] During the operation of hair styling tools, components such as ion generators generate a lot of heat. If heat cannot be dissipated in a timely and effective manner, it will not only affect the normal operation of the ion generator, leading to unstable water ion generation and affecting the hair styling effect, but may also damage the hair due to excessive temperature, reducing the user experience. Moreover, some existing hair styling tools have design flaws in their heat dissipation structure, and airflow can easily enter the installation cavity during the heat dissipation process, disrupting the environment for condensation of water droplets in the ion generator and further affecting the generation of water ions.

[0004] Therefore, developing a heat dissipation structure for hair styling appliances that can effectively solve the heat dissipation problem while ensuring the stability of water ion generation is of great practical significance. Utility Model Content

[0012] Furthermore, the connection between the second heat sink and the heat dissipation port is made by a sealing material.

[0013] Furthermore, the air duct and the mounting cavity are isolated by the second heat sink.

[0014] Furthermore, both the first heat sink and the second heat sink are provided with a heat dissipation surface that communicates with the air duct.

[0015] Furthermore, the first heat sink divides the mounting cavity into chamber one and chamber two. Chamber one and the air duct are separated by the second heat sink. The ion generator is disposed in chamber one, and chamber two is connected to the air duct.

[0016] Furthermore, the first heat sink is connected to the bottom end of the condenser plate, and the central axis L1 of the first heat sink is arranged parallel to the central axis L2 of the ion needle.

[0017] Furthermore, the first heat sink is connected to the sidewall of the condenser plate, and the central axis L1 of the first heat sink is perpendicular to the central axis L2 of the ion needle.

[0018] Furthermore, the mounting cavity is also provided with a bracket for fixing the ion generator, and the bracket is provided with a pressure plate, which abuts against the first heat sink.

Detailed Implementation

[0043] 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.

[0044] like Figure 1-7As shown, this utility model provides an ion structure for a hair styling tool, including a housing 1 and a heating element 5. The housing 1 has an air duct 11, and a motor 3 is housed within the air duct 11. A mounting cavity 12 is located beside the air duct 11 between the heating element 5 and the motor 3. The mounting cavity 12 has an ion generator 2 and an emission port 151 corresponding to the ion generator 2. At least a portion of the ion generator 2 can communicate with the air duct 11 through a heat dissipation surface 233 for heat exchange. The ion generator 2 includes an ion needle 21, which is not connected to the air duct 11. In this embodiment, by placing the mounting cavity 12 between the heating component 5 and the motor 3, it can ensure that when the motor 3 drives external cold air into the air duct 11, the cold air acts on the heat dissipation surface 233 of the ion generator 2 to the maximum extent. This allows the cold air in the air duct 11 to directly and quickly remove the heat from the ion generator 2, thereby ensuring that the ion needle 21 has a stable and good low-temperature working environment and further improving the ion generation effect. On the other hand, it can not only prevent the cold air from contacting the ion needle 21 of the ion generator 2, ensuring the ion generation environment in the ion generator 2 and thus improving the stability of ion generation, but also ensure that the ions generated by the ion generator 2 can act more fully and effectively on the hair through the emission hole 151, making the hair styling effect more significant and the hair quality better protected.

[0045] It should be noted that the ion generator 2 can be a water ion generator or a positive / negative ion generator, etc. In this embodiment, the ion generator 2 can preferably be a water ion generator.

[0046] Preferably, the housing 1 is provided with an arc-shaped protrusion 15, the inner wall of which forms the inner wall of the mounting cavity 12. This provides a larger accommodating space for the assembly of the ion generator 2, preventing the mounting cavity 12 from occupying too much space in the air duct 11, thereby affecting the wind speed and air volume. The emission hole 151 is located on the arc-shaped protrusion 15, which allows for better control of the emission direction and range of ions. This facilitates the timely and smooth discharge of ions generated by the ion needle 21 through the emission hole 151, providing sufficient and stable ion resources for hair care.

[0047] Specifically, such as Figure 5As shown, the ion generator 2 further includes a condenser plate 22 and a heat sink 23. The heat sink 23 includes a first heat sink 231 and a second heat sink 232 connected to each other. The condenser plate 22 is thermally connected to the ion needle 21 and the first heat sink 231, respectively. The first heat sink 231 and the second heat sink 232, or the second heat sink 232, are provided with a heat dissipation surface 233 that communicates with the air duct 11. This allows the heat on the condenser plate 22 to be transferred to the first heat sink 231 and / or the second heat sink 232, and then transferred to the cold air in the air duct 11 through the heat dissipation surface 233. Finally, the cold air in the air duct 11 contacts the heat dissipation surface 233 and carries away the heat when it flows. By setting the first heat sink 231 and the second heat sink 232, not only is the heat dissipation area increased, but the cold air in the air duct 11 can also directly act on the heat sink 23, improving the heat dissipation efficiency and effectively solving the problem of poor heat dissipation caused by the isolation between the installation position of the ion generator 2 and the air duct 11 in the traditional technology. In practical applications, the condenser 22 and the heat sink 23 can be an integral structure, or the condenser 22 can replace the whole structure. Therefore, by setting at least a part of the integral structure or the condenser 22 on the heat dissipation surface 233 and exposing it directly in the air duct 11, the purpose of heat dissipation can also be achieved.

[0048] Specifically, such as Figure 6-12 As shown, in some embodiments, the heat dissipation surface 233 may be disposed on the second heat sink 232, as detailed below: In one embodiment, such as Figure 6-8 As shown, the air duct 11 and the mounting cavity 12 are separated by a partition 13: A partition 13 separates the air duct 11 from the mounting cavity 12. The partition 13 and the inner wall of the housing 1 enclose the mounting cavity 12, which is isolated from the air duct 11. The partition 13 has a heat dissipation vent 131, and the second heat sink 232 is fitted into the heat dissipation vent 131, so that the heat dissipation surface 233 is connected to the air duct 11. This structure allows the second heat sink 232 to be connected to the air duct 11, so that the cold air in the air duct 11 can directly act on the second heat sink 232, carrying away the heat generated by the ion generator 2 and improving the heat dissipation efficiency. On the other hand, this fitted connection can effectively prevent airflow from entering the mounting cavity 12, avoiding damage to the environment where water droplets condense in the ion generator 2 and ensuring the stability of water ion generation. At the same time, the setting of the heat dissipation vent 131 also makes the heat dissipation structure more compact, saving space and facilitating the miniaturization and portability of hair styling tools.

[0049] Preferably, the second heat sink 232 and the heat dissipation port 131 can be tightly connected, that is, the outer diameter of the second heat sink 232 is slightly larger than the inner diameter of the heat dissipation port 131. During assembly, the second heat sink 232 is pressed into the heat dissipation port 131 by external force, and the friction between the two is used to achieve a stable connection. This interference fit not only ensures the tight fit between the second heat sink 232 and the partition 13, preventing airflow from entering the mounting cavity 12 from the connection, but also reduces the obstruction of heat transfer, allowing the heat on the heat sink 23 to dissipate more quickly, and improving the overall stability and reliability of the heat dissipation structure. Meanwhile, considering the convenience of installing and disassembling the heat sink 23, the connection between the second heat sink 232 and the heat dissipation port 131 can also be connected by a sealing material, such as glue or sealing ring. This ensures the stability of the connection between the heat sink 23 and the partition 13, while also facilitating subsequent maintenance and replacement.

[0050] It should be noted that the heat dissipation surface 233 can be arranged at an angle on the second heat sink 232 (e.g., Figure 6-7 As shown), the heat dissipation surface 233 forms an angle with the air outlet direction of the air duct 11, thereby further increasing the contact area between the cold air and the second heat sink 232, thus improving the heat dissipation effect; at the same time, the surface of the heat dissipation surface 233 is a smooth and flat plane, which facilitates the reduction of resistance and noise when cold air flows; in some embodiments (such as... Figure 11 and 12 The heat dissipation surface 233 can also be configured to be parallel to the air outlet direction of the air duct 11.

[0051] Furthermore, such as Figure 9 As shown, in some embodiments, the first heat sink 231 and the second heat sink 232 are generally L-shaped, or the left end of the second heat sink 232 extends to form an inverted T-shape (not shown). The first heat sink 231 is connected to the bottom end (right side wall) of the condenser 22. In this case, the central axis L1 of the first heat sink 231 is parallel to or coincides with the central axis L2 of the ion needle 21. This arrangement makes the heat transfer path more reasonable, and the heat on the condenser 22 can be transferred more smoothly to the first heat sink 231, and then dissipated through the second heat sink 232. Moreover, it is more compact in spatial layout, which is conducive to the optimization of the overall structure, reduces unnecessary space occupation, and makes the internal structure of the hairdressing tool more compact and reasonable, making it easy to carry and use. It should be noted that in practical applications, the first heat sink 231 can also be connected to the side wall of the condenser 22 ( Figure 9The first heat sink 231 is connected to the lower wall of the condenser 22. In this case, the first heat sink 231 can be adapted to the shape of the side wall of the condenser 22, effectively transferring heat from the condenser 22 to the first heat sink 231. This connection method not only meets heat dissipation requirements but also provides more flexibility in the overall structural design. The connection position between the first heat sink 231 and the condenser 22 can be flexibly adjusted according to the layout of other components inside the hair styling tool to achieve optimal space utilization and heat dissipation. In this embodiment, the first heat sink 231 is preferably connected to the bottom end of the condenser 22, which increases the contact area between the condenser 22 and the first heat sink 231, improving the heat dissipation effect.

[0052] like Figure 10 As shown, in one embodiment, the first heat sink 231 and the second heat sink 232 can also be arranged parallel to each other. In this case, the first heat sink 231 is connected to the side wall (lower wall) of the condenser 22, and the central axis L1 of the first heat sink 231 is perpendicular to the central axis L2 of the ion needle 21. This not only does not affect heat dissipation but also makes the heat sink 23 easier to manufacture and process, thus reducing production costs. The first heat sink 231 and the second heat sink 232 can be attached to each other or connected by connecting pieces, so that the first heat sink 231 and the second heat sink 232 form an "I"-shaped structure. In practical applications, with the first heat sink 231 and the second heat sink 232 arranged parallel to each other, the first heat sink 231 can also be connected to the bottom end of the condenser 22 (e.g., Figure 10 The connection to the right wall of the condenser 22 can be adapted according to the shape of the condenser 22 and the shape of the first heat sink 231, and is not limited here.

[0053] In one embodiment, such as Figure 11-12 As shown, the air duct 11 and the mounting cavity 12 are isolated by the second heat sink 232: The air duct 11 and the mounting cavity 12 are separated by the second heat sink 232, and the heat dissipation surface 233 is connected to the air duct 11. That is, the second heat sink 232 serves both as a heat dissipation component and as an isolation structure between the air duct 11 and the mounting cavity 12. This fully utilizes the position and function of the second heat sink 232, achieving a dual function of heat dissipation and isolation. This avoids the need for an additional partition 13, reduces the number of components used, lowers production costs, and simplifies the internal structure of the hair styling appliance, improving overall space utilization. Furthermore, the second heat sink 232 acting as an isolation component not only increases the contact area between the air duct 11 and the heat sink 23, further enhancing heat dissipation efficiency, but also ensures the stability of water ion generation, resulting in a significant performance improvement for the hair styling appliance. It should be noted that in this embodiment, the first heat sink 231 and the second heat sink 232 can also be L-shaped, inverted T-shaped, or arranged parallel to each other. The specific connection structure between the heat sink 23 and the condenser fin 22 has been fully explained above and will not be repeated here.

[0054] Specifically, such as Figure 13-14 As shown, in some embodiments, the heat dissipation surface 233 can also be simultaneously disposed on the first heat sink 231 and the second heat sink 232, as detailed below: The first heat sink 231 divides the mounting cavity 12 into a first chamber 126 and a second chamber 127. The first chamber 126 and the air duct 11 are separated by the second heat sink 232, making the first chamber 126 a sealed space. The ion generator 2 is disposed in the first chamber 126, while at least a portion of the second chamber 127 is connected to the air duct 11. At this time, the heat dissipation surface 233 is disposed on both the first heat sink 231 and the second heat sink 232 and is connected to the air duct 11. This reduces the installation space of the ion generator 2, making the ion generator 2 more compact in the first chamber 126. On the one hand, it allows for more direct and efficient heat transfer, and on the other hand, it reduces the area of ​​the second heat sink 232, thus reducing production costs. In addition, since the second chamber 127 is connected to the air duct 11, the first heat sink 231 is also connected to the air duct 11, further increasing the contact area between the cold air in the air duct 11 and the heat sink 23, thereby improving heat dissipation efficiency.

[0055] In this structure, the first heat sink 231 and the second heat sink 232 can be L-shaped as a whole, or a portion of the second heat sink 232 can extend towards the second chamber 127, making the overall structure of the first heat sink 231 and the second heat sink 232 in an inverted T-shape. At the same time, the second chamber 127 is still connected to the air duct 11, thereby increasing the contact area between the second heat sink 232 and the air duct 11 and improving the heat dissipation efficiency. The specific connection structure between the heat sink 23 and the condenser fin 22 has been fully explained above and will not be repeated here. Furthermore, dividing the mounting cavity 12 into two chambers via the first heat sink 231 enhances the stability of the overall structure, allowing the heat dissipation structure to better maintain its shape and function under external forces, thus extending the service life of the hair styling appliance. Simultaneously, it facilitates individual maintenance and replacement of the ion generator 2, reducing repair costs and improving product maintainability.

[0056] Specifically, such as Figure 3 , Figure 7 As shown, the housing 1 is also equipped with a high voltage generator 24, which is electrically connected to the ion needle 21 to provide the required high voltage to the ion needle 21, so that the ion needle 21 can generate a corona discharge phenomenon, thereby ionizing water molecules into water ions. In this embodiment, the high-voltage generator 24 is disposed within the mounting cavity 12, and the ion generator 2 is disposed downstream of the high-voltage generator 24 along the air outlet direction of the air duct 11. This ensures that the electric field generated by the high-voltage generator 24 stably acts on the ion needle 21, thereby guaranteeing the efficiency and stability of water ion generation. Furthermore, placing the high-voltage generator 24 within the mounting cavity 12 avoids interference from the external environment, such as dust and moisture, improving the operational reliability and service life of the high-voltage generator 24. Simultaneously, since the ion generator 2 is disposed downstream of the high-voltage generator 24 along the air outlet direction of the air duct 11, the cold air within the air duct 11, while carrying away heat from the heat sink 23, will not affect the electrical connection between the high-voltage generator 24 and the ion generator 2, ensuring the stable operation of the entire hair styling appliance's heat dissipation structure.

[0057] In some embodiments, since the first heat sink 231 divides the mounting cavity 12 into a first chamber 126 and a second chamber 127, the high-voltage generator 24 can be disposed in the second chamber 127. This results in a more rational spatial layout, making full use of the internal space of the mounting cavity 12 and making the overall structure more compact. When the second chamber 127 is connected to the air duct 11, it can dissipate heat to a certain extent with the help of the cold air in the air duct 11, ensuring good air circulation around the high-voltage generator 24. This helps to reduce its operating temperature, avoids direct heat interference between the high-voltage generator 24 and the ion generator 2, ensures the stability of the water ion generated by the ion generator 2, extends its service life, and thus improves the reliability and stability of the entire hair styling appliance's heat dissipation structure.

[0058] Furthermore, in this embodiment, the first heat sink 231 and the second heat sink 232 are integrally formed, which not only enhances the overall structural strength of the heat sink 23 and reduces the thermal resistance that may be generated at the connection points, but also facilitates the uniform distribution and rapid conduction of heat. In addition, it simplifies the production process, reduces manufacturing costs, and improves assembly efficiency.

[0059] Specifically, such as Figure 7 , Figure 15 As shown, the mounting cavity 12 is also provided with a bracket 121 for fixing the ion generator 2. The bracket 121 is provided with a pressure plate 122. The pressure plate 122 is arranged parallel to the first heat sink 231. When the heat sink 23 is installed into the housing 1, the side of the first heat sink 231 away from the condenser 22 abuts against the pressure plate 122, thereby limiting and fixing the heat sink 23 between the condenser 22 and the pressure plate 122. This can prevent the heat sink 23 from shifting due to unbalanced force during installation, improve assembly efficiency, and make the overall structure simpler, more stable and reliable.

[0060] In this embodiment, the pressure plate 122 can also be configured such that, after the heat sink 23 is installed, the side of the pressure plate 122 closest to the second heat sink 232 abuts against the second heat sink 232. This allows the pressure plate 122 to limit the heat sink 23 both axially and radially, further enhancing the stability of the heat sink 23 installation. This effectively prevents problems such as loosening or displacement that may occur during long-term use or when subjected to external impacts, ensuring the stable performance of the heat dissipation structure. Simultaneously, this configuration provides precise positioning during assembly, making the installation of the heat sink 23 faster and more accurate.

[0061] Preferably, the pressure plate 122 is provided with a hook 123. When the heat sink 23 is inserted into the housing 1 from top to bottom, the hook 123 will engage with the upper end face of the first heat sink 231 of the heat sink 23, thereby further fixing the heat sink 23 and preventing it from shifting in the installation direction. This double fixing method greatly improves the stability and reliability of the heat sink 23 installation. Even in harsh environments such as high temperature, high humidity or vibration, it can ensure that the heat sink 23 can operate stably for a long time without loosening or falling off.

[0062] Preferably, since the high-voltage generator 24 is disposed in the mounting cavity 12, the bracket 121 is also provided with a limiting plate 124 and a limiting plate 125, so that the limiting plate 124, the limiting plate 125, the pressure plate 122, the partition plate 13 or the second heat sink 232 form a cavity adapted to the high-voltage generator 24, and the high-voltage generator 24 can be placed in this cavity to play a good role in fixing and protecting the high-voltage generator 24.

[0063] Specifically, such as Figure 16-18 As shown, the housing 1 of this utility model includes a detachably connected upper housing 16 and a lower housing 17. The heating component 5 includes a first heating plate 51 and a second heating plate 52 respectively disposed on the upper housing 16 and the lower housing 17. Both the first heating plate 51 and the second heating plate 52 are provided with heating elements 53. The first heating plate 51 and the second heating plate 52 are arranged opposite to each other and can move closer or further away from each other to clamp or loosen the hair, so as to achieve styling effects such as straightening or perming. A fixing frame 18 is provided between the second heating plate 52 and the lower shell 17. The fixing frame 18 is adapted to the lower shell 17 and surrounds the lower shell 17 to form part of the air duct 11. The fixing frame 18 has air outlets 181 on both sides that communicate with the air duct 11. The second heating plate 52 is fixed between the two air outlets 181 on both sides. The other end of the shell 1 has an air inlet 14. The air inlet 14 communicates with the air duct 11 and the air outlets 181 to form an effective air convection path to ensure that external cold air can smoothly enter the air duct 11.

[0064] Furthermore, the fixing bracket 18 has an integrally formed fixing cover 182 at one end near the motor 3. When the fixing bracket 18 is installed, the fixing cover 182 covers the motor 3, thereby pressing the motor 3 firmly into the air duct 11, ensuring the stability and reliability of the motor 3 in the air duct 11, effectively preventing loosening or displacement caused by vibration or external impact during operation, and thus reducing noise.

[0065] Furthermore, a circuit board assembly 4 is also provided inside the upper shell 16 and the lower shell 17. The circuit board assembly 4 is electrically connected to the ion generator 2, the high voltage generator 24, the motor 3, and the heating element 53, and is used to control the operation of the entire hair styling appliance. The circuit board assembly 4 is located between the air inlet 14 and the ion generator 2. On the one hand, it can make full use of the cold air entering through the air inlet 14 to dissipate heat from the circuit board assembly 4, avoiding the circuit board assembly 4 from overheating due to long-term operation, or being affected by the heat generated by the heating element 53, so as to reduce its performance and service life. On the other hand, this layout makes the internal structure of the entire hair styling appliance more compact and orderly, and the connection and wiring between the components are more convenient and reasonable, reducing electromagnetic interference and other problems.

[0066] The innovation of this utility model lies in the provision of a heat dissipation component that is heat-transferringly connected to the condenser plate. At least a portion of the heat dissipation component is connected to the air duct, allowing the cold air in the air duct to directly act on the heat dissipation component when it flows, and quickly remove the heat from the heat dissipation component. This ensures that the ion needle has a stable and good low-temperature working environment, further improving the ion generation effect. At the same time, by preventing the ion needle from being connected to the air duct, the cold air is effectively prevented from entering the installation cavity and damaging the environment for condensation of water droplets on the ion needle, thereby ensuring the stability of water ion generation.
