Detailed Implementation

[0044] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the 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 scope of protection of this utility model.

[0045] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0046] like Figures 1 to 4 As shown, the hair styling tool of this utility model includes a housing 1, a heating component 3, a cover fastener 113, and an electronic control device 8.

[0047] The outer casing 1 of the hair styling tool includes a front casing 11 and a back casing 12. It should be noted that the side of the heating assembly 3 of the outer casing 1 containing the heat insulation element 34 (described later) is the front of the outer casing 1, corresponding to the front casing 11; the side of the outer casing 1 facing away from the heat insulation element 34 (described later) is the back of the outer casing 1, corresponding to the back casing 12. The end of the outer casing 1 containing the heat insulation element 34 (described later) is the front end, corresponding to the "front" of the front inner mounting bracket 23 of the inner mounting bracket 2 (described later); the end of the outer casing 1 furthest from the heat insulation element 34 (described later) is the rear end, corresponding to the "rear" of the rear inner mounting bracket 24 of the inner mounting bracket 2 (described later).

[0048] The heating component 3 of the hair styling tool includes a heating element 31, a heat insulation element 34, and a heat transfer element 32 that is in direct or indirect contact with the heating element 31. The heat transfer element 32 is provided with a heat transfer comb 328, and the heat insulation element 34 is provided with a heat insulation comb 348 that is inserted into the heat transfer comb 328. The heat insulation comb 348 has a portion located outside the outer casing 1. The heat transfer element 32 and the heating element 31 are in direct contact without any other object, or the heat transfer element 32 is in indirect contact with the heat transfer element 31 through the heat insulation element 34 (described later), allowing the heating element 31 to transfer heat to the heat transfer element 32. Typically, there are multiple heat transfer combs 328 and heat insulation combs 348 arranged in a staggered manner; the periphery of the heat insulation element 34 is provided with columnar bodies 349.

[0049] The hair styling tool's electronic control device 8 is connected to a power supply 89 and is electrically connected to the heating element 31. This electronic control device 8 is located inside the housing 1 and is fixedly connected to the front housing 11. The electronic control device 8 is a PCB circuit board or similar device equipped with an MCU, capable of controlling the activation and other states of the heating element 31. The power supply 89 is a rechargeable battery, such as a lithium battery. Alternatively, the power supply 89 can be a device that provides electrical energy, such as a rectifier connected to AC mains power. The power supply 89 is electrically connected to a power connector 891 with a Type-C interface to supply power to the electronic control device 8 and to the rechargeable battery power supply 89, etc.

[0050] like Figure 13 As shown, the front housing 11 is provided with a cover-closing through hole 112, and the back housing 12 is provided with a back housing mounting hole 122. The cover-closing fastener 113 passes through the cover-closing through hole 112 and connects to the back housing mounting hole 122, so that the front housing 11 and the back housing 12 are fixedly connected. When viewed from above (along the heat insulation comb 348, from the front housing 11 to the back housing 12), the cover-closing through hole 112 is completely located inside the heat insulation member 34. Generally, for the rear part of the housing 1, the connection strength requirement between the front housing 11 and the back housing 12 in this part is not high, and the front housing 11 can be provided with a cover-closing buckle 114 to engage with the back housing 12. The cover fastener 113 can be a screw, clip, or other plug-in structure that can achieve locking and fixing, or it can be a structure that is connected by adhesive. For example, the cover fastener 113 and the front shell 11 are an integral structure. After applying adhesive to one end of the cover fastener 113, it is bonded to the mounting hole 122 of the back shell. It should also be understood that the cover fastener 113 passes through the cover through hole 112 and connects to the mounting hole 122 of the back shell.

[0051] The working principle is as follows: Before assembly, the front shell 11 and the back shell 12 are in a state of separation. After the heat transfer component 32 and the electronic control device 8 are fixed on the front shell 11, the cover fastener 113 is passed through the cover through hole 112 and connected to the back shell mounting hole 122, so that the front shell 11 and the back shell 12 surround and are fixedly connected. Finally, the heat insulation comb 348 and the heat transfer comb 328 are inserted and fixed (the fixing method can be glue bonding or the method listed in the following embodiments), so that when viewed from above, the cover through hole 112 is completely located inside the heat insulation component 34. At this time, the cover fastener 113 is blocked by the heat insulation component 34 and cannot be observed. The cover through hole 112 and the cover fastener 113 are not exposed, so they have better waterproof and dustproof properties and tactile feel. As can be seen from the above, the hair styling tool of this utility model, while ensuring strength by connecting the front shell 11 and the back shell 12 through the cover fastener 113, has better waterproof and dustproof properties and a better tactile feel because the cover through hole 112 and the cover fastener 113 are not exposed.

[0052] As one specific implementation, the hair styling tool also includes an inner mounting frame 2 and a front housing fastener 221. The heating element 31 and / or the electronic control device 8 are located between the inner mounting frame 2 and the front housing 11 and are fixed relative to the inner mounting frame 2. For example, the heating element 31 is fixed relative to the inner mounting frame 2 via a heat transfer element 32. The inner mounting frame 2 and the front housing 11 clamp the electronic control device 8, thus fixing the electronic control device 8 relative to the inner mounting frame 2. The inner mounting frame 2 is provided with a front housing connection hole 22, and the front housing 11 is provided with a front housing fastener hole 111. The front housing fastener 221 passes through the front housing connection hole 22 and connects to the front housing fastener hole 111. Figure 12 As shown, it is easy to understand that the front housing fastener 221 is connected to the front housing fastener hole 111 from the back of the housing 1 towards its front. Therefore, after the front housing 11 and the back housing 12 are closed, the front housing fastener 221 is completely located inside the housing 1. Before the back housing 12 and the front housing 11 are closed, the front housing fastener 221 is exposed from the opening of the front housing 11. After placing the heating element 31 and / or the electronic control device 8 into the front housing 11 and then placing the inner mounting bracket 2, the front housing fastener 221 can be easily operated with tools such as screwdrivers. In summary, while ensuring the installation strength of the heating element 31 and / or the electronic control device 8, the assembly of the heating element 31 and / or the electronic control device 8 is facilitated.

[0053] As one specific implementation, the heat transfer element 32 is provided with a clamped body 321; the inner mounting frame 2 is provided with a clamping platform 231. The inner wall of the outer shell 1 and the clamping platform 231 clamp the clamped body 321, thereby fixing the heating component 3 relative to the outer shell 1 and the inner mounting frame 2. Typically, the clamping platform 231 has an L-shaped cross-section, and its horizontally protruding part is clamped by the outer shell 1 and the clamping platform 231. During assembly, the heating component 3 is first moved so that the clamped body 321 fits against the inner wall of the outer shell 1. Then, the inner mounting frame 2 is installed, and the inner wall of the outer shell 1 and the clamping platform 231 clamp the clamped body 321 to complete the assembly of the front outer shell 11, the inner mounting frame 2, and the heating component 3, which is relatively convenient.

[0054] As one specific implementation, one of the heat insulation component 34 and the inner mounting bracket 2 is provided with a mounting clip groove 341, and the other is provided with a mounting clip 21 that abuts against the inner wall of the mounting clip groove 341. The mounting clip 21 moves along the direction of insertion of the heat transfer comb 328 and the heat insulation comb 348 and engages with the mounting clip groove 341. It is easy to understand that the mounting clip 21 is elastic and can engage with the mounting clip groove 341 through elastic deformation. In the final step of assembly, the heat insulation component 34 is moved toward the back shell 12, so that the heat transfer comb 328 and the heat insulation comb 348 are inserted at the same time, and the mounting clip 21 engages with the mounting clip groove 341. This simplifies the assembly steps and ensures the installation strength of the heat insulation component 34, making it less likely to fall off. The heat transfer comb 328 is misaligned (e.g. Figure 7 As shown, referring to the aforementioned front-back direction, the direction perpendicular to the front-back direction on the horizontal plane is the transverse direction. This misalignment means that the positions of two adjacent heat transfer combs 328 in the transverse direction have a gap in the aforementioned front-back direction and are not on the same transverse reference line.

[0055] As one of the specific implementation methods, such as Figure 8 , 9 As shown, one of the heat transfer comb 328 and the heat insulation comb 348 is provided with a comb groove 327, and the other is provided with a comb protrusion 347 embedded in the comb groove 327. The heat transfer comb 328 has a portion exposed from the side (front or rear side) of the heat insulation comb 348. This increases the exposed heating area of ​​the heat transfer comb 328. The bottom of the heat insulation component 34 is completely open or has a strip-shaped limiting strip (the limiting strip is not shown in the attached drawing, but may be indicated by other means). Figure 6 As shown, the limiting strip is in Figure 6 As shown in the figure, it is arranged along the aforementioned front-back direction; the limiting strip is used to contact and position itself with the heat transfer substrate 322 of the heat transfer element 32; thus, when using hair styling tools, the contact area between hair (not shown in the figure) and the heat transfer substrate 322 of the heat transfer element 32 can be increased.

[0056] As one of the specific implementation methods, such as Figure 8 , 9 As shown, the top of the heat transfer comb 328 and / or the top of the inner wall of the heat insulation comb 348 are provided with comb end grooves 326. The heat insulation comb 348 can directly contact the human body, and the comb end grooves 326 can further improve the heat insulation effect.

[0057] As one specific embodiment, the inner mounting bracket 2 includes a front inner mounting bracket 23 and a rear inner mounting bracket 24; the heating element 31 is located between the front inner mounting bracket 23 and the front outer shell 11, and the electronic control device 8 is located between the rear inner mounting bracket 24 and the front outer shell 11; the rear inner mounting bracket 24 is provided with an extension slot 242, and the front inner mounting bracket 23 is provided with an extension 232; the extension 232 is inserted into the extension slot 242. The rear inner mounting bracket 24 can slide back and forth relative to the front inner mounting bracket 23, and vice versa. During assembly, the rear inner mounting bracket 24 and the front inner mounting bracket 23 can be finely adjusted in position to facilitate the assembly of the electronic control device 8 and the heating component 3.

[0058] As one specific implementation, the electronic control device 8 is electrically connected to an operation input device 88, which includes a toggle switch 881 and / or a push-button switch 882 mounted on the housing 1. The operation input device 88 is used to send electrical signals to the electronic control device 8, such as disconnecting the electronic control device 8 from the power supply 89. The push-button switch 882 sends an electrical signal by pressing the button and changes the electrical signal by resetting the button. The toggle switch 881 (commonly known as a toggle switch) sends an electrical signal by toggling the toggle switch. This prevents accidental activation of the push-button switch 882, improving electrical safety (e.g., accidentally activating the heating element 31 during baggage handling due to accidental activation of the push-button switch 882).

[0059] As one specific implementation, the electronic control device 8 is provided with an output device 87. The output device 87 is a device for outputting electrical signals of the electronic control device 8, such as a digital tube, for displaying electrical signals transmitting temperature information of the heating element 31, etc., output by the electronic control device 8. The outer casing 1 also includes a light-transmitting element 871 embedded in the front outer casing 11. It is easy to understand that the light-transmitting element 871 has light transmittance, such as acrylic glass. Figure 10 As shown, when viewed from above, the output device 87 is completely located within the light-transmitting element 871, and there is a portion inserted into the light-transmitting element 871. For hair styling tools, displaying the temperature of the heating element 31, etc., is necessary, therefore the output device 87 must be provided. However, the outer shell 1 is usually not light-transmitting, so the light-transmitting element 871 is required; but with the output device 87 and the light-transmitting element 871 in place, the operation of inserting the output device 87 into the light-transmitting element 871 is difficult in the conventional structure. During assembly, when assembling the hair styling tool of this utility model, it is relatively easy to first embed the light-transmitting element 871 into the front outer shell 11, and then move the electronic control device 8 to insert the output device 87 into the light-transmitting element 871. With the extension slot 242 provided in the rear inner mounting bracket 24 and the extension 232 provided in the front inner mounting bracket 23, it is also easy to fine-tune the position of the electronic control device 8 to insert the output device 87 into the light-transmitting element 871, and then the remaining assembly can be completed according to the aforementioned process. In summary, it is convenient to assemble the alignment of the light-transmitting element 871 and the output device 87.

[0060] As one specific implementation, the front casing 11 has a negative ion output port 119; a negative ion generator (not shown in the attached figure) is fixedly installed inside the casing 1, facing the negative ion output port 119, and the negative ion generator is electrically connected to the electronic control device 8. The negative ion generator is a device for generating negative ions in the prior art, such as the negative ion generator in CN220511905U, etc., and its working principle and model will not be described here. The electronic control device 8 controls the negative ion generator to start working, ionizing air molecules into negative ions. The negative ions enter the external environment through the negative ion output port 119. The grounding strip of the negative ion generator is used to contact the human body to achieve charge balance and prevent frizzy hair.

[0061] like Figures 6 to 10 As shown, the heating component for hair styling tools in an embodiment of the present invention includes a heating component 3; the heating component 3 includes a heating element 31, a heat transfer element 32, and a mounting element 33; the heating component 3 also includes at least one of a temperature sensor 81 and a fuse 82.

[0062] The heating element 31 of the heating assembly 3 is sheet-shaped and capable of generating heat when energized. For example, the heating element 31 consists of two parallel MCH heaters that generate heat when energized.

[0063] The heat transfer element 32 of the heating component 3 is provided with a heat transfer comb 328.

[0064] The temperature sensor 81 of the heating component 3 is used to detect the temperature of the heating element 31, such as an NTC component. When in use, the temperature sensor 81 is electrically connected to the electronic control device 8. It detects the temperature of the heating element 31 and feeds the temperature signal back to the electronic control device 8. Combined with the operation input device 88 or the built-in program control of the electronic control device 8, the heating element 31 is controlled, thereby realizing the control of the temperature of the heating element 31.

[0065] The fuse 82 of the heating component 3 can melt and cut off the power to the heating element 31 when its temperature reaches the set value. That is, the fuse 82 is an overheat fuse, which will melt when its temperature is too high.

[0066] The mounting member 33 of the heating assembly 3 has two ends extending away from the heating element 31 to form elastic protrusions 331. These elastic protrusions 331 are fixedly connected to the heat transfer element 32 (for example, the heating assembly 3 also includes mounting screws 339, which pass through the elastic protrusions 331 and screw into the heat transfer element screw holes 329 of the heat transfer element 32, thus fixing the elastic protrusions 331 to the heat transfer element 32). This allows the mounting member 33 to directly or indirectly abut against the heating element 31 (i.e., the heat transfer element 32 and the mounting member 33 directly clamp the heating element 31, or clamp the heating element 31 through the heat-insulating member 35 described later). The mounting member 33 is provided with an elastic support body 332, which clamps the temperature sensor 81 and / or the fuse 82. It is easy to understand that the mounting member 33 has a through hole (not shown in the attached figure) to avoid obstructing the temperature sensor 81 and the fuse 82. For the embodiments described later that include a heat-insulating element 35, the heat-insulating element 35 is provided with a through hole (not shown in the attached figure) to avoid the temperature sensor 81 and the fuse 82.

[0067] The working principle is as follows: when assembling the heating component 3, the temperature sensor 81 and / or fuse 82 are placed into their corresponding elastic support body 332. Then, the mounting part 33 is brought close to the heating element 31 and the elastic protrusion 331 is fixedly connected to the heat transfer element 32 respectively. This allows the heat transfer element 32 and the mounting part 33 to clamp the heating element 31, which can conveniently complete the assembly of the heating component 3. At the same time, the elastic force provided by the elastic support body 332 makes the heating element 31 closely adhere to the heat transfer element 32, and the temperature sensor 81 and / or fuse 82 are closely adhered to the heating element 31. This can ensure the heat transfer effect of the heating element 31 to the heat transfer element 32 and the accuracy of the temperature of the heating element 31 and / or the reliability of overheat protection.

[0068] As one specific implementation, the mounting member 33 is elongated, with elastic protrusions 331 located at both ends along its length. Multiple elastic support bodies 332 correspond to the fuse 82. These multiple elastic support bodies 332 are all perpendicular to the mounting member 33 (i.e., perpendicular to its length) and arranged opposite each other. "Against each other" means that one elastic support body 332 points towards the root of an adjacent elastic support body 332. Because the fuse 82 has a larger diameter and longer length than the temperature sensor 81, the supporting force exerted on it by the elastic support bodies 332 should be evenly distributed. The multiple elastic support bodies 332 are all perpendicular to the mounting member 33 and arranged opposite each other, ensuring that the elastic support bodies 332 are positioned along the fuse 82, thus guaranteeing a uniform distribution of the supporting force on the fuse 82.

[0069] As one specific implementation, the elastic support 332 corresponding to the temperature sensor 81 is arranged along the elongated mounting member 33.

[0070] As one specific implementation, the heat transfer element 32 is provided with a clamping body 321 with an L-shaped cross-section. As mentioned above, the assembly of the front outer shell 11, the inner mounting bracket 2, and the heating assembly 3 is relatively convenient.

[0071] As one specific implementation, the heating assembly 3 also includes a heat-insulating element 35. The heat transfer element 32 is made of metal, such as a flexible steel sheet, which has higher strength and thermal conductivity than plastic. The heat-insulating element 35 abuts against the mounting element 33 and the heating element 31. The heat-insulating element 35 can prevent the heat from the heating element 31 from being transferred to the mounting element 33, preventing the heat-insulating element 35 from overheating and burning the outer shell 1 and inner mounting bracket 2 made of plastic or the like.

[0072] As one specific implementation, the heat transfer element 32 is provided with a positioning protrusion 325, the heating elements 31 are multiple in parallel, and the heat insulation element 35 is provided with a positioning opening 351; the positioning protrusion 325 passes through the space between two adjacent heating elements 31 and fits snugly into the positioning opening 351. This ensures accurate alignment between the heat transfer element 32 and the heat insulation element 35, preventing misalignment of the heat transfer element 32 and the heat insulation element 35, which could cause the heating element 31 to be exposed from the heat insulation element 35, scalding the plastic outer shell 1 and the inner mounting bracket 2, etc.

[0073] As one specific implementation, as mentioned above, the heating assembly 3 also includes a heat insulation member 34, which is provided with a heat insulation comb 348 that is inserted into the heat transfer comb 328.

[0074] As one specific implementation, the heat transfer comb 328 has a comb groove 327 or a comb protrusion 347 on its side (one or both sides). This ensures the strength of the connection between the heat transfer comb 328 and the heat insulation comb 348.

[0075] As one specific implementation method, as mentioned above, the top end of the heat transfer comb 328 is provided with a comb end groove 326.

[0076] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
