Abstract
Description
Technical Field
[0001] The utility model belongs to the field of product processing, and specifically relates to a control structure for the opening and closing angle of a direct-heating hair comb. Background Art
[0002] A hair straightener is one of the commonly used hair styling tools. Specifically, it heats and softens the hair through a heating element and then cools it to achieve the purpose of straightening the hair. When in use, the two clamping arms need to be opened, then the hair is placed between the two clamping arms, and finally the two clamping arms clamp the hair and slide along the extending direction of the hair; for the convenience of use, most hair straighteners are provided with springs so that the hair straightener is in a state where the two clamping arms are open under normal conditions without external force, and corresponding limiting structures are also provided to prevent the two clamping arms from freely rotating and the opening angle from being too large; for example, in the technical solution of the publicly disclosed technical literature "CN213720417U, a hair straightener convenient to use": under normal conditions, under the elastic force of the hinge spring 29, it opens at a certain angle, and after use, it will automatically return to the normal state under the elastic restoring force of the hinge spring 29;
[0003] In the above structure, the automatic expansion of the two clamping arms can be realized, and the expansion angle can be limited. However, each manufacturer has different understandings of the expansion angle and the limiting method, so a limiting scheme different from the above structure is proposed. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a control structure for the opening and closing angle of a direct-heating hair comb to solve the problems raised in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A control structure for the opening and closing angle of a direct-heating hair comb includes a first clamping arm and a second clamping arm that are rotatably connected. An air flow generating component is installed in the first clamping arm, and the air flow generating component is connected to a wind guiding component located on the first clamping arm or / and the second clamping arm. A cover plate is fixedly provided between the two sides of the first clamping arm and the second clamping arm;
[0007] A limiting structure is provided at the cover plate. The limiting structure is respectively connected to the first clamping arm and the second clamping arm for limiting the opening angle between the two.
[0008] As a further technical solution, the limiting structure includes a strip hole provided on the cover plate. An active part is provided at the strip hole. The active part is respectively rotatably connected to a first connecting rod and a second connecting rod. The other ends of the first connecting rod and the second connecting rod are respectively rotatably connected to a first fixing part and a second fixing part. The first fixing part and the second fixing part are respectively connected to the first clamping arm and the second clamping arm.
[0009] Further technical solution: The structures of the first fixing part and the second fixing part are the same. The first fixing part includes a fixing plate, on which there is a convex block. An activity groove extending to the bottom of the fixing plate is provided on the convex block, and the first connecting rod extends into the activity groove and is rotatably connected to the convex block.
[0010] Further technical solution: The limiting structure includes a first limiting block and a second limiting block provided at the end of the cover plate. The first limiting block and the second limiting block respectively correspond to the first clamping arm and the second clamping arm. A first buckling position and a second buckling position are respectively provided on both sides of the first clamping arm and the second clamping arm, and the first limiting block and the second limiting opening can be placed in the first buckling position and the second buckling position.
[0011] Further technical solution: The air flow generating component includes a flexible three-way air duct. One end of the three-way air duct forms an air inlet part, and the other two ends form air outlet parts, which are symmetrically arranged at intervals and extend in the opposite direction relative to the air inlet part;
[0012] The air outlet part includes a first connecting section and a second connecting section. The first connecting section is connected to the air inlet part, and the second connecting section is connected to the air guiding component.

[0014] Further technical solution: A noise reduction net is provided at the air inlet end of the blower, and the noise reduction net is connected to the installation seat.
[0015] The beneficial effects of the present utility model:
[0016] First, during the continuous opening process of the first clamping arm and the second clamping arm, as the angle gradually becomes larger, the first connecting rod and the second connecting rod will be pulled, causing the movable part to slide from one end to the other along the strip hole. Moreover, the opening angle of the first connecting rod and the second connecting rod will be larger. Eventually, due to the length limitation of the first connecting rod and the second connecting rod, the first clamping arm and the second clamping arm cannot be further opened, thus limiting the opening angle of the first clamping arm and the second clamping arm;
[0017] Second, during the opening process of the first clamping arm and the second clamping arm, the first buckling position and the second buckling position move along an arc trajectory, causing the first limiting block and the second limiting block to respectively enter the first buckling position and the second buckling position, thereby restricting the further rotation of the first clamping arm and the second clamping arm;
[0018] The limiting structure in the present utility model is provided on the cover plates on both sides and provides two different ways to limit the opening angle of the first clamping arm and the second clamping arm from the prior art; it provides more solutions for different types of products in actual production to meet the production needs.

Detailed Description of the Preferred Embodiments
[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
[0026] Please refer to Figures 1-4 ;
[0027] The control structure of the present utility model is used to limit the opening range of the two clamping arms in the direct-heating hair comb. First, the structure of the direct-heating hair comb will be described. Specifically, it includes a first clamping arm 1 and a second clamping arm 2 that are rotatably connected. An air flow generating component 3 is installed in the first clamping arm 1. In this embodiment, an air guiding component 4 is provided in the first clamping arm 1 or the second clamping arm 2, or both are provided with an air guiding component 4, which is not limited herein. In addition, the structure of the air guiding component 4 is not limited either. Specifically, reference can be made to the relevant structures in the prior art. A cover plate 5 is fixedly provided between the two sides of the first clamping arm 1 and the second clamping arm 2 for covering the electronic components and other parts installed inside; a limiting structure is provided at the cover plate 5. The limiting structure is respectively connected to the first clamping arm 1 and the second clamping arm 2 for limiting the opening angle between the two.
[0028] There are two implementation manners for the limiting structure in the present utility model;
[0029] Embodiment 1, referring to Figure 2 , specifically including a strip hole 61 provided on the cover plate 5, where a movable member 62 is provided at the strip hole 61. The movable member 62 is respectively rotatably connected to a first connecting rod 63 and a second connecting rod 64. More specifically, the first connecting rod 63 and the second connecting rod 64 are rotatably connected with the movable member 62 as an intermediate member, so that the first connecting rod 63 and the second connecting rod 64 are in a "V" shape. The other ends of the first connecting rod 63 and the second connecting rod 64 are respectively rotatably connected to a first fixing part 65 and a second fixing part 66. The first fixing part 65 and the second fixing part 66 are respectively connected to the first clamping arm 1 and the second clamping arm 2. Preferably, the first fixing part 65 and the second fixing part 66 are installed at positions close to the working area;
[0030] When the first clamping arm 1 and the second clamping arm 2 rotate and open, they synchronously drive the first connecting rod 63 and the second connecting rod 64 to rotate and open around the movable member 62. During the continuous opening process of the first clamping arm 1 and the second clamping arm 2, as the angle gradually increases, the first connecting rod 63 and the second connecting rod 64 will be pulled, causing the movable member 62 to slide from one end to the other end along the strip hole 61. And the opening angle of the first connecting rod 63 and the second connecting rod 64 will be larger. Eventually, due to the length limitation of the first connecting rod 63 and the second connecting rod 64, the first clamping arm 1 and the second clamping arm 2 cannot be further opened, thus forming a limitation on the opening angle of the first clamping arm 1 and the second clamping arm 2.
[0031] In this embodiment, the structures of the first fixing part 65 and the second fixing part 66 are the same. In one of the structures of the first fixing part 65 and the second fixing part 66, it can specifically be a block fixedly arranged on the first clamping arm 1 and the second clamping arm 2, and then respectively rotatably connected to the first connecting rod 63 and the second connecting rod 64. In another structure, taking the first fixing part 65 as an example for illustration, the first fixing part 65 includes a fixing plate 651. The fixing plate 651 is horizontally arranged, and its two sides respectively correspond to the two sides of the first clamping arm 1. A convex block 652 is provided on the fixing plate 651, and a movable groove 653 extending to the bottom of the fixing plate 651 is provided on the convex block 652. The first connecting rod 63 extends into the movable groove 653 and is rotatably connected to the convex block 652.
[0032] Embodiment 2, referring to Figure 3 , specifically including a first limiting block 71 and a second limiting block 72 provided at the end of the cover plate 5. The first limiting block 71 and the second limiting block 72 respectively correspond to the first clamping arm 1 and the second clamping arm 2. Clamping positions 73 and 74 are respectively provided on both sides of the first clamping arm 1 and the second clamping arm 2; when the first clamping arm 1 and the second clamping arm 2 are in a closed state, the clamping positions 73 and 74 are respectively in a separated state from the first limiting block 71 and the second limiting block 72; during the opening process of the first clamping arm 1 and the second clamping arm 2, the clamping positions 73 and 74 move along an arc trajectory, so that the first limiting block 71 and the second limiting block 72 respectively enter the clamping positions 73 and 74, thereby restricting the further rotation of the first clamping arm 1 and the second clamping arm 2;
[0033] It should be noted that when the limiting block 1 71 and the limiting block 2 72 enter and exit the buckle position 1 73 and the buckle position 2 74, the buckle position 1 73 and the buckle position will be slightly deformed to make room for the limiting block 1 71 and the limiting block 2 72 to enter and exit smoothly;
[0034] In addition, the limit block 1 71 and the limit block 2 72 are not completely engaged with the buckle position 1 73 and the buckle position 2 74, otherwise the limit block 1 71 and the limit block 2 72 cannot be separated from the buckle position 1 73 and the buckle position 2 74. An interference portion 75 extends from the lower edge of the buckle position, and the interference portion 75 can interfere with the inner side surface of the limit block, thereby also having a limiting effect.
[0035] Preferably, according to the structure in the first embodiment, a fixing plate 6511 and a fixing plate 6512 respectively connected to the clamping arm 1 and the clamping arm 2 2 may also be provided, and the buckle position 1 73 and the buckle position 2 74 are provided on the fixing plate 6511 and the fixing plate 6512.
[0036] Reference Figure 4 The airflow generating assembly 3 in the present invention has a heating function, so that the temperature of the blown air flow is more stable, and specifically comprises a flexible three-way air duct 31. In the present embodiment, the flexible three-way air duct 31 is integrally formed by a soft material, one end of the flexible three-way air duct 31 forms an air inlet 311, and the other two ends form air outlets 312, which are symmetrically arranged at intervals and extend in the opposite direction relative to the air inlet 311; a mounting seat 32 is fixedly arranged at the periphery of the air inlet 311, and a heating assembly 33 and a fan 34 are arranged on the mounting seat 32, and the air inlet 311, the heating assembly 33 and the fan 34 are distributed in sequence and coaxially arranged; the two air outlets 312 are respectively connected to the air guide assemblies 4 of the two clamp arms; a mounting seat 32 is fixedly arranged at the periphery of the air inlet 311, and a heating assembly 33 and a fan 34 are arranged on the mounting seat 32, and the relative positions of the air inlet 311, the heating assembly 33 and the fan 34 are fixed by the limitation of the mounting seat 32.
[0037] The utility model is provided with an independent heating component 33 between the soft three-way air duct and the fan 34, which can independently heat the airflow without being affected by other factors. At the same time, the soft three-way air duct, the heating component 33 and the fan 34 are formed into a standard installation module through the mounting seat 32, making assembly and application more convenient.
[0038] During operation, the fan 34 sucks in external air flow and conveys it to the heating component 33. The heating component 33 heats the air flow, causing its temperature to rise. Then, the heated air flow enters from the air inlet part 311 of the flexible tee duct and is divided into two air flows that are output from the two air outlet parts 312 respectively. In this embodiment, the air inlet part 311, the heating component 33, and the fan 34 are arranged coaxially in sequence, which can minimize the resistance of the air flow as much as possible, reach the tee duct more directly, and reduce the generation of noise.
[0039] Furthermore, a controller should be provided. For example, multiple adjustment gears can be set in the controller to control the temperature of the heating component 33. When in use, the user can select the corresponding gear according to their preference, thereby controlling the temperature of the heating component 33, that is, controlling the temperature of the hot air blown out to meet different needs of the user.
[0040] In addition, a noise reduction net 35 is provided at the air inlet end of the fan 34. The noise reduction net 35 is connected to the mounting seat 32 to further reduce the air inlet noise.
[0041] One embodiment of the present utility model regarding the air outlet part 312 includes a connecting section one 3121 and a connecting section two 3122. The connecting section one 3121 is connected to the air inlet part 311, and the connecting section two 3122 is connected to the air guiding component 4. A telescopic section 3123 is provided between the connecting section one 3121 and the connecting section two 3122; during the opening or closing process of the clamping arm one 1 and the clamping arm two 2, the telescopic section 3123 will be stretched or compressed simultaneously. Adopting such a design can reduce the tensile force on the air outlet part 312 compared with the traditional structure, greatly relieve the fatigue of the air outlet part 312, and improve the service life.
[0042] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
[0043] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard 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.
