Description

Technical Field

[0001] This utility model belongs to the field of hair straighteners, specifically relating to a hair straightener with double-sided four-way surrounding convection airflow. Background Technology

[0002] A hair straightener, also called an electric hair straightener, works by heating the heating element or heating wire with an electric current, which then conducts the heat to an aluminum or ceramic plate, causing the hair to heat up and soften. The hair is then cooled to achieve the purpose of straightening the hair.

[0003] However, in most hair straighteners on the market, the heating element or heating wire is usually directly fixed to the handle. When the hair straightener is working, the heat from the heating element is transferred to the handle. Continuous use can easily cause the handle to overheat, which can easily cause burns when consumers hold the hair straightener to style their hair. At the same time, most existing hair straighteners fix the heating element to the handle with clips or screws. This assembly process is cumbersome and disassembly is difficult during maintenance. Therefore, there is an urgent need for a hair straightener that is easy to assemble and can better insulate the heat from the heating element. Utility Model Content

Detailed Implementation

[0034] 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.

[0035] like Figure 1-5 As shown, this utility model provides a hair straightener with double-sided four-way surrounding convection airflow, including an inner support assembly 1 and two clamping plates 2 and 3 arranged vertically and vertically. The inner support assembly 1 is provided with an air inlet 11 and an air outlet 12, which are located at the front and rear ends of the inner support assembly 1, respectively. In use, the airflow enters the inner support assembly 1 through the air inlet 11 and exits through the air outlet 12. One end of the clamping plate 2 and the clamping plate 3 are respectively hinged to the inner support assembly 1, and the hinge point is located on the side of the inner support assembly 1 near the air inlet 11. Air guide assemblies 4 are provided on the end face of the clamping plate 2 near the clamping plate 3 and on the end face of the clamping plate 3 near the clamping plate 2. The two air guide assemblies 4 are arranged vertically and vertically, and the rear ends of the two air guide assemblies 4 are connected to the air outlet 12.

[0036] The air guide assembly 4 includes an aluminum plate 41 and an air guide box 42. The air guide box 42 has an installation cavity 421 with an opening facing the other air guide box 42. The aluminum plate 41 is disposed in the installation cavity 421, so that the aluminum plates 41 in the two air guide assemblies 4 are arranged opposite to each other.

[0037] It should be noted that the aluminum plate 41 is provided with a heating element (not shown) that has a heating function. When in use, the hair is placed between the two aluminum plates 41 arranged above and below, and the hair straightener is pulled in the direction of the hair. Through the pressing effect between the aluminum plates 41 and the heating effect, the hair is softened, straightened and styled.

[0038] During installation, the aluminum plate 41 is first installed in the mounting cavity 421 of the air guide box 42 to form an integrated air guide assembly 4, and then the air guide assembly 4 is installed on the first clamp 2 or the second clamp 3. When the consumer holds and uses the hair straightener, since the air guide box 42 is set between the aluminum plate 41 and the first clamp 2 or the second clamp 3, the air guide box 42 can better absorb the heat emitted by the aluminum plate 41 towards the first clamp 2 or the second clamp 3, thereby achieving the purpose of heat insulation to prevent the consumer from being burned by the first clamp 2 or the second clamp 3.

[0039] Meanwhile, during mass production and assembly, the aluminum plate 41 can be installed in the mounting cavity 421 of the air guide box 42 in batches and assembled into the air guide assembly 4. Then, the air guide assembly 4 can be installed on the clamping plate 2 or the clamping plate 3 in batches, thereby effectively improving the assembly convenience and efficiency of the hair straightener. This solves the problems in the prior art, such as low assembly efficiency of hair straighteners and unreasonable design of hair straighteners that can easily lead to accidental burns to consumers, thus affecting the user experience.

[0040] Specifically, along the length direction (front-back direction) of the inner support component 1, the front end peripheral wall of the air guide box 42 is provided with an outwardly protruding snap-fit ​​block 422, the snap-fit ​​block 422 is provided with an insertion hole 4221 communicating with the mounting cavity 421, and the front end of the aluminum plate 41 is provided with an insertion block 411 corresponding to the insertion hole 4221.

[0041] During installation, the aluminum plate 41 is located in the mounting cavity 421 and moves forward toward the insertion hole 4221, so that the front wall of the aluminum plate 41 abuts against the inner wall of the snap-fit ​​block 422 of the air guide box 42, thereby restricting the further forward movement of the aluminum plate 41. At this time, the insertion block 411 is fixedly inserted into the insertion hole 4221, and at the same time, the peripheral wall of the insertion block 411 abuts against the inner wall of the insertion hole 4221, thereby effectively preventing the front end of the aluminum plate 41 from shaking, and also effectively preventing the aluminum plate 41 from falling out of the mounting cavity 421.

[0042] Furthermore, in order to more effectively fix the aluminum plate 41 to the air guide box 42, two symmetrically arranged "L"-shaped guide grooves 423 are provided on the inner walls of the rear two sides of the air guide box 42, and "L"-shaped guide blocks 412 corresponding to the guide grooves 423 are provided on the rear two sides of the aluminum plate 41, and the guide blocks 412 are slidably connected in the guide grooves 423.

[0043] The guide groove 423 and the guide block 412 provide guidance for the forward insertion of the aluminum plate 41 into the air guide box 42. At the same time, the "L" shaped structure design effectively prevents the aluminum plate 41 from shaking, thereby giving the aluminum plate 41 a better overall fixation effect and improving the user experience.

[0044] Specifically, within the mounting cavity 421 of the second clamping plate 3, and on either side of the aluminum plate 41 in the left-right direction, comb teeth 5 are arranged in an array along the front-back direction. When the first clamping plate 2 and the second clamping plate 3 clamp the hair, the length direction of the hair is nearly perpendicular to the length direction (front-back direction) of the hair straightener and the comb teeth 5. Therefore, the hair slides through the comb teeth 5. During the process of pulling the hair straightener, the comb teeth 5 can straighten the hair, thereby improving the straightening effect for consumers.

[0045] Furthermore, the comb teeth 5 are arranged in an array along the front-back direction with a length slightly less than or equal to the length of the aluminum plate 41, so that the comb teeth 5 can work with the aluminum plate 41 to straighten and heat the hair clamped between the two aluminum plates 41 evenly, thereby improving the straightening effect.

[0046] Preferably, the comb teeth 5 can be fixedly connected to the air guide box 42 by screws or by snap-fit ​​structure, thereby ensuring the stability of the comb teeth 5 in use;

[0047] It should be noted that the comb teeth 5 can be positioned on the clamping plate 2 and / or the clamping plate 3, both of which can achieve the straightening effect of the comb teeth 5.

[0048] Specifically, the air guide assembly 4 also includes a fixing cover 43; the fixing cover 43 is disposed on the end face of the air guide box 42 facing away from the aluminum plate 41, and the fixing cover 43 is fixedly connected to the air guide box 42 by screws. By providing a two-layer structure of the air guide box 42 and the fixing cover 43 between the aluminum plate 41 and the clamping plate 1 or the clamping plate 2, the heat insulation effect on the aluminum plate 41 is improved, further enhancing the user's comfort; at the same time, the fixing of the fixing cover 43 makes the air guide assembly 4 more compact and its overall rigidity stronger, thereby improving the service life and product quality of the hair straightener.

[0049] Furthermore, such as Figure 5-6 As shown, an air guide cavity 44 is provided between the fixed cover 43 and the air guide box 42. The air guide cavity 44 is connected to the air outlet 12. Air outlets 6 are provided on both the left and right sides of the air guide assembly 4. The air outlets 6 are connected to the air guide cavity 44. The air outlets 6 are directed towards the hair in the clamped state. In use, the airflow enters the air guide cavity 44 from the air outlet 12 and then exits from the air outlet 6 and blows towards the hair. By allowing the airflow to flow between the aluminum plate 41 and the air guide box 42, the heat emitted by the aluminum plate 41 is carried away, thereby achieving better heat insulation and heat dissipation. At the same time, the air outlets 6 ensure that the airflow continuously blows towards the hair during the straightening process, thereby drying and cooling the hair quickly and preventing damage to the hair caused by excessively high temperature of the aluminum plate 41 or excessively long straightening time.

[0050] Furthermore, such as Figure 7-10 As shown, in order to achieve better blow-drying effect for the hair in the clamped state, the air outlets 6 at both ends of the air guide component 4 in the first clamp 2 are arranged in a one-to-one correspondence with the air outlets 6 at both ends of the air guide component 4 in the second clamp 3. That is to say, the airflow blown out by the air outlets 6 in the first clamp 2 and the second clamp 3 respectively acts on the upper and lower ends of the same hair, further increasing the drying area of ​​the hair, thereby achieving the effect of fast hair drying.

[0051] Preferably, the air outlet 6 is elongated and extends along the front-to-back direction. Multiple air outlets 6 can be provided and arranged in an array along the front-to-back direction. The overall length of the air outlet 6 on either side of the air guide component 4 is close to or the same as the length of the comb teeth 5, so that the air outlet 6 can cooperate with the comb teeth 5, thereby increasing the air drying area of ​​the hair straightener and improving the straightening effect of the hair straightener.

[0052] Specifically, such as Figure 6As shown, the air guide cavity 44 is also provided with a plurality of air guide ribs 441, which are fixedly connected to or integrally formed with the air guide box 42; wherein, the plurality of air guide ribs 441 form two groups, left and right, and the left and right groups of air guide ribs 441 correspond one-to-one with the left and right air outlets 6 respectively, and the plurality of air guide ribs 441 in each group are spaced apart along the front-back direction; an air guide channel 442 is formed between adjacent air guide ribs 441 in the front-back direction, one end of the plurality of air guide channels 442 is connected to the air supply port 12, and the other end is connected to the corresponding air outlet 6;

[0053] By setting the air guide ribs 441, the airflow in the air guide cavity 44 can flow evenly to the multiple air outlets 6, so that the multiple air outlets 6 can achieve uniform airflow, thereby improving the air drying effect of the hair straightener and the heat dissipation effect of the aluminum plate 41.

[0054] Furthermore, such as Figure 8 As shown in Figure 9, the air outlet 6 includes a left air outlet 61 disposed on the left side of the air guide assembly 4 and a right air outlet 62 disposed on the right side of the air guide assembly 4; the left air outlet 61 includes an upper left air outlet 611 disposed in the clamping plate 1 2 and a lower left air outlet 612 disposed in the clamping plate 2 3, and the right air outlet 62 includes an upper right air outlet 621 disposed in the clamping plate 1 2 and a lower right air outlet 622 disposed in the clamping plate 2 3;

[0055] To more clearly describe the technical solution of the air outlet 6 of this utility model, the following two embodiments are provided;

[0056] In Example 1, as Figure 7-8 As shown, the left air outlet 61 and the right air outlet 62 are both disposed on the end face of the air guide component 4 facing the other air guide component 4 disposed opposite to it; thereby reducing the distance between the air outlet 6 and the hair in the clamped state, and thus enhancing the airflow.

[0057] Specifically, in terms of the air outlet direction, the inner wall of the left air outlet 61 is parallel to the vertical axis L, so that the airflow directions from the upper left air outlet 611 and the lower left air outlet 612 coincide. That is, the airflow from the upper left air outlet 611 and the lower left air outlet 612 is blown out vertically, thereby effectively shortening the distance between the left air outlet 61 and the hair to increase the air volume.

[0058] The inner wall of the right air vent 62 is arranged in an alternating direction with the vertical direction, so that the airflow from the right air vent 62 is blown out at an angle. At this time, the flow direction of the airflow forms an angle A with the vertical direction. Compared with the vertical exhaust airflow of the left air vent 61, the angled exhaust airflow of the right air vent 62 can increase the contact area between the airflow and the hair, which can also achieve the effect of drying hair quickly, thereby improving the drying efficiency.

[0059] Preferably, the included angle A is set between 5-45° for optimal hair straightening effect.

[0060] In Example 2, as Figure 9-10 As shown, the left air outlet 61 is disposed on the end face of the air guide assembly 4 facing the other air guide assembly 4 disposed opposite it, while the right air outlet 62 is disposed on the side wall of the air guide assembly 4 near the end face; wherein, the clamping plate 1 2 and the clamping plate 2 3 are provided with side air outlets 63 on the side wall of the same side as the right air outlet 62, and the side air outlets 63 are aligned with the right air outlet 62; during operation, part of the airflow in the air guide cavity 44 is discharged vertically from the left air outlet 61, while the other part of the airflow passes through the right air outlet 62 and the side air outlet 63 in sequence and is discharged.

[0061] Furthermore, when the clamping plates 1 and 2 are driven close together and closed, a contact surface 7 is formed between the clamping plates 1 and 2. In the air outlet direction, the inner wall of the left air outlet 61 is perpendicular to the contact surface 7, so that the airflow directions blown from the upper left air outlet 611 and the lower left air outlet 612 are the same. That is, the airflow blown from the upper left air outlet 611 and the lower left air outlet 612 is blown out vertically, which can also effectively shorten the distance between the left air outlet 61 and the hair to increase the air volume.

[0062] The inner walls of the right air vent 62 and the side air vent 63 are arranged in an alternating direction with the contact surface 7, so that the airflow from the side air vent 63 is blown out at an angle. At this time, the flow direction of the airflow forms an angle B with the contact surface 7. Compared with the vertical exhaust airflow of the left air vent 61, the angled exhaust airflow of the right air vent 62 and the side air vent 63 can increase the contact area between the airflow and the hair, which can also achieve the effect of drying hair quickly, thereby improving the drying efficiency.

[0063] Preferably, the included angle B is set between 5-30° for optimal hair straightening effect.

[0064] Furthermore, the air outlet area of ​​the right air outlet 62 is smaller than that of the side air outlet 63, thereby preventing the airflow from the right air outlet 62 from being obstructed due to the side air outlet 63 being too small, thus preventing convection and reducing the air outlet effect.

[0065] It should be noted that the air outlet 6 in the above two embodiments adopts an air outlet scheme that combines vertical air outlets and inclined air outlets set on the left and right sides, thereby improving the air drying effect of the air outlet 6 of the hair straightener, so that consumers can quickly dry and cool their hair when straightening it.

[0066] Meanwhile, the vertical air outlet of the left air outlet 61 and the inclined air outlet of the right air outlet 62 are only one embodiment of this technical solution. In actual production, the positions of the left air outlet 61 and the right air outlet 62 can be interchanged without affecting the actual user experience.

[0067] Specifically, such as Figure 11-12 As shown, the clamping plate 2 and the clamping plate 3 are provided with a receiving cavity 8 for installing the air guide assembly 4. The front end of the receiving cavity 8 is provided with a limiting step 81 corresponding to the snap-fit ​​block 422 of the air guide box 42. The snap-fit ​​block 422 is provided with a limiting step 4222 corresponding to the limiting step 81. During assembly, the air guide assembly 4 is placed in the receiving cavity 8, and the limiting step 81 and the limiting step 4222 are correspondingly abutted and fixed, so that the air guide assembly 4 is fixedly connected to the clamping plate 2 or the clamping plate 3.

[0068] Furthermore, a limiting block 82 is provided on the inner wall of the receiving cavity 8, and a limiting groove 431 corresponding to the limiting block 82 is provided on the peripheral wall of the fixing cover 43. Both the limiting block 82 and the limiting groove 431 are "L" shaped structures. By setting the limiting block 82 and the limiting groove 431, the connection stability between the air guide assembly 4 and the clamping plate 2 or the clamping plate 3 is further improved.

[0069] Furthermore, the rear end of the air guide box 42 is provided with a fixing block 424 extending toward the inner support component 1. The receiving cavity 8 is provided with a fixing post 83 corresponding to the fixing block 424. During installation, the air guide component 4 is installed in the receiving cavity 8. The first limiting step 81 and the second limiting step 4222 are correspondingly abutted and fixed. The fixing block 424 is also synchronously abutted and fixed with the fixing post 83. At this time, the fixing block 424 and the fixing post 83 are fixedly connected by screws, thereby realizing the assembly and fixation of the air guide component 4 with the first clamp 2 or the second clamp 3.

[0070] Specifically, such as Figure 13As shown, the inner support assembly 1 is also equipped with a circuit board 13, a button 14, a fan 15, and a heating frame 16. The circuit board 13 is electrically connected to the button 14, the fan 15, the heating frame 16, and the aluminum plate 41. In use, the consumer can start and stop the fan 15, the heating frame 16, and the aluminum plate 41 through the button 14, thereby facilitating the consumer's quick and easy direct hair washing operation.

[0071] The following is a detailed explanation of the working principle of this utility model;

[0072] During assembly, the aluminum plate 41 is first installed in the air guide box 42 to form an integrated air guide assembly 4. Then, the air guide assembly 4 is installed on the clamping plate 2 or the clamping plate 3. Next, the clamping plate 2 and the clamping plate 3 are respectively hinged to the inner support assembly 1. At the same time, the rear end of the air guide assembly 4 in the clamping plate 2 and the clamping plate 3 is connected to the front end of the inner support assembly 1, so that the air guide cavity 44 in the air guide assembly 4 is connected to the air outlet 12 in the inner support assembly 1.

[0073] In use, place the hair between the first clamp 2 and the second clamp 3, and press the hair straightener with your fingers so that the first clamp 2 and the second clamp 3 clamp the hair. At this time, the upper and lower aluminum plates 41 clamp the hair respectively and the hair passes through the comb teeth 5. After the hair straightener is turned on, the aluminum plates 41 emit heat to heat and straighten the hair. The left air outlet 61 and the right air outlet 62 simultaneously blow air vertically and obliquely onto the hair respectively. At this time, pull the hair straightener along the length of the hair to achieve simultaneous straightening, combing and quick drying of the hair.

[0074] The innovation of this utility model lies in setting an air guide box between the aluminum plate and the clamping plate, which allows the air guide box to quickly absorb the heat emitted by the aluminum plate, thereby isolating the heat transfer between the aluminum plate and the clamping plate to prevent consumers from being burned by the clamping plate; at the same time, by first installing the aluminum plate on the air guide box to assemble it into an integrated air guide assembly, and then installing the air guide assembly on the clamping plate, the assembly convenience and assembly efficiency of the hair straightener are effectively improved.

[0075] By using comb teeth, a vertical left air vent, and a tilted right air vent, the system allows consumers to further comb their hair while drying and cooling it for styling during the straightening process, thus improving the user experience.

[0076] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0077] 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. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
