Description

Technical Field

[0001] The utility model belongs to the technical field of hair care tools, in particular to a hair straightener with a wind outlet function. Background Art

[0002] A hair straightener is one of the common hair care tools. Currently, the hair straighteners on the market are not limited to the hair straightening function, but also have the function of blowing air to meet the different needs of customers. For example, in the public technical document "CN112754128A, air-cooled hair straightener structure", in its technical solution, a first cavity 101 is provided in the lower clamping plate 100, and the two ends of the top of the lower clamping plate 100 are respectively provided with a first air outlet 102 and a first installation position, the lower heating plate assembly 110 is provided in the first installation position, and the fan 120 is provided at one end of the first cavity 101 close to the first air outlet 102; for details, please refer to the relevant description in paragraph 0042 of the specification;

[0003] Based on the above technical solution, the hair straightening operation can be achieved while also blowing the hair to achieve the effect of drying and straightening the hair. However, for a product, not only its function but also the user experience should be considered. The opening angle of the hair straightener based on the above solution is very limited, so how to make the hair more convenient to enter the two clamping arms is an issue that needs to be focused on.

[0004] In addition, for example, in the Chinese patent document "CN117958540A, a hair straightener", in the specific working process, the fan blades are driven by the motor to rotate and the heating element generates heat to blow out hot air from the first strip-shaped air outlet. When the hair is clamped by the clamping strip through the opposite movement of the hair clamp plates, the hair can be heated; because the blown airflow needs to pass through the hair straightening heating component, the airway is relatively narrow, and the airflow is subject to greater resistance, resulting in unsmooth air flow, or greater internal air pressure and noise. In addition, relying on the heating element in the hair clamp plate for heating has the following problems;

[0005] 1. The temperature of the airflow is unstable and cannot be adjusted.

[0006] 2. Due to the absorption of the temperature of the heating element, the heat generated by the hair clip plate will be moved over a large range, which will affect the straightening effect;

[0007] When the blown air flow needs to be heated, the heating element must be turned on and cannot be operated independently, resulting in energy waste. Utility Model Content

DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0048] Please refer to Figure 1-16 ;

[0049] The hair straightener of the utility model has an air outlet function, which can achieve the effect of quickly drying the hair 7, and specifically includes an airflow generating part 2, and the airflow generating part 2 has two output ends, which are respectively connected to the clamp arm 1 11 and the clamp arm 2 12. The main body to be protected by the utility model is a hair straightener. According to the prior art, the use of the hair straightener should be to clamp the hair 7 by the clamp arm 1 11 and the clamp arm 2 12, and heat the hair 7 at the same time to achieve the purpose of shaping the hair 7. Therefore, one or both of the clamp arm 1 11 and the clamp arm 2 12 in this embodiment have a heating function, which can achieve the effect of heating the hair 7, and in this embodiment, The hair straightening heating component 41 disposed in the clamp arm has not been improved, so the structure in the prior art can be used therein. In addition, an elastic member 42 can be disposed between the hair straightening heating component 41 and the clamp arm to achieve the floating of the hair straightening heating component 41 and avoid clamping the hair 7. In this embodiment, the clamp arm 1 11 and the clamp arm 2 12 have and only have one side provided with at least one air outlet 13. It should be noted that an air passage is formed between the air outlet 13 and the airflow generating part 2, and the airflow generating part 2 will output from the air outlet 13. When performing the hair straightening operation, the airflow can be blown out at the same time to perform double drying and softening shaping on the hair 7.

[0050] When the unfolding rotation angle of the clamp arm 11 and the clamp arm 2 12 is not large enough, it will cause the problem of difficulty in entering the hair. Therefore, the utility model forms a "V"-shaped groove 14 at the end of the clamp arm 11 and the clamp arm 2 12. When the user uses it, the hair 7 enters from the end surface. The "V"-shaped groove 14 can play a guiding role and guide the hair 7 to the middle position between the clamp arm 11 and the clamp arm 2 12; and when the hair 7 enters the straight hair area between the clamp arm 11 and the clamp arm 2 12, the edge position of the clamp arm 11 and the clamp arm 2 12 may cause the hair 7 to enter the straight hair area between the clamp arm 11 and the clamp arm 2 The hair 7 causes obstruction, so that the hair 7 is piled up and difficult to arrange in the process of entering the hair straightening area. Therefore, in this embodiment, the clamp arm 11 and the clamp arm 2 12 are combined on at least the same side to form a groove 2 15. By providing the groove 2 15, a clearance position is formed on the sides of the clamp arm 11 and the clamp arm 2 12, which will not hinder the entry of the hair 7. The utility model forms an "L"-shaped hair entry position by smoothly transitioning the groove 14 and the groove 2 15 to each other, so that the hair 7 can enter the hair straightener more smoothly, so as to improve the user experience.

[0051] There is another way of using the device, in which the user can directly put the hair 7 into the second groove 15 and pass the hair 7 out from the other side of the second groove 15, thereby providing the customer with more usage options.

[0052] In addition, the groove 2 15 is only arranged on one side of the clamp arm 1 and the clamp arm 2, and the other side of the clamp arm 1 11 and the clamp arm 2 12 is a hair styling curved surface 19; this product is a tool for hair 7 care and styling, which can provide a curling function in addition to straight hair. After the hair 7 is clamped by the clamp arm 1 1 and the clamp arm 2 12, the hair straightener can also be rotated to make the hair 7 contact with the hair styling curved surface 19 formed by the clamp arm 1 1 and the clamp arm 2 12, thereby achieving the purpose of curling the hair.

[0053] Furthermore, the groove 1 14 and the groove 2 15 are connected, that is, they have a smooth transition. When in use, the hair 7 will enter the straight hair area toward the groove 1 14, and will also enter the straight hair area toward the bend where the groove 1 14 and the groove 2 15 are smoothly connected.

[0054] Preferably, the edge positions of the clamp arm 1 11 and the clamp arm 2 12 are designed as an arc surface b. The arc design position here is specifically the position corresponding to the hair straightening area. Since the hair straightener is often not in a straight line with the hair 7 during the hair straightening operation, the hair 7 will conflict with the edge position of the clamp arm 1 11 or the clamp arm 2 12. When the edge position is set in a straight line, the contact area with the hair 7 is very small, and the relative movement will cause damage to the hair 7. Therefore, the use of the arc surface design can not only increase the contact area, but also reduce the resistance during relative movement and make the movement smoother.

[0055] Regarding the specific structure of the air cavity 33, for example, reference can be made to the relevant description of "CN117958540A-A hair straightener", where the airflow passes through the heating component 41 and then blows out from the air outlet; in this embodiment, the air cavity 33 and the heating component 41 are independent of each other, for example, an independent box body 3 is provided in the clamp arm to form an independent air cavity 33, refer to Figure 4 The box body 3 is provided with a second air outlet 34 connected to the first air outlet 13 to avoid noise and unsmooth air flow caused by gas leakage. In addition, the airflow generating part 2 has a heating function, that is, it is independent of the heating components 41 in the clamping arm 11 and the second clamping arm 12. The airflow can increase the temperature without passing through the hair straightening heating component 41 to dry the hair 7;

[0056] In addition, the air duct for air flow output in the utility model is separated from the hair straightening heating component 41, so that the heat of the hair straightening heating component 41 will not be lost in the process of air flow output to the outside, so that the heating temperature of the hair straightener is more stable in the process of heating and caring for the hair 7, and the air flow temperature is more stable by adopting the method of independently heating the air flow;

[0057] Furthermore, a controller should be provided in the hair straightener. For example, a plurality of adjustment gears can be set in the controller to control the airflow temperature of the airflow generating part 2. The user can select the corresponding gear according to preference, that is, the temperature of the hot air blown out is controlled without affecting the heating component 41, so that the temperature is adjustable. Alternatively, the heating component 41 can be turned off, and the user can choose to use a separate blowing function. At this time, hot air can still be generated to meet the different needs of the user.

[0058] Preferably, the box body 3 includes an upper shell 31 and a lower shell 32. The edges of the upper shell 31 and the lower shell 32 are provided with a concave-convex structure 38 for fitting connection, which can effectively achieve a sealing effect. Of course, a sealing gasket can be arranged at the right position to increase its sealing performance.

[0059] In actual production, the position of the air outlet 13 will be adjusted, and the box body 3 is fixedly installed in the shell. In order to connect the air outlet 13 with the air outlet 2 34, in this embodiment, the air outlet 2 34 arranged on one side of the box body 3 is moved down to keep the same height with the air outlet 13 to achieve installation, and the bottom surface of the lower shell 32 near the air outlet 2 34 is an inclined arc transition a to make the air flow smooth; refer to Fig.13 and Fig.15 At the same time, the bottom surface of the lower shell 32 near the air outlet 34 is an inclined arc surface a, which matches the shape of the heating component 41 that is high in the middle and low on both sides. The space is compact and reasonable, which is conducive to reducing the size of the overall hair straightener.

[0060] In the present utility model embodiment, refer to Fig.16 The length L of the box body 3 is ≤ three times the width W, the thickness D is equal to or less than half of the width W, the thickness H of the heating component 41 is approximately equal to the thickness D of the box body 3, the thickness of the clamp arm can be reduced, and the area of ​​the heating zone of the heating component 41 can be ensured. At the same time, the thickness of the hair straightener is ensured to facilitate the flipping or curling of the hair straightener during use, that is, the increase in the length and width directions is equivalent to increasing the working surface, while the increase in the thickness direction does not increase the working surface and has no beneficial effect, and the length is greater than the width, which is conducive to clamping a wider strand of flat hair 7 at a time.

[0061] At least one arc-shaped guide plate 35 is provided in the air cavity 33, which divides the interior of the air cavity 33 into at least one air duct. Usually, the air cavity 33 is rectangular, and the entire space needs to be filled when the airflow is output. At this time, the airflow will encounter greater resistance, which will not only cause unsmooth air output but also cause greater noise. Therefore, the arc-shaped guide plate 35 is provided to enable the airflow to smoothly change angles and reduce its resistance, so as to solve the problems of noise and unsmooth air output.

[0062] There are three implementation methods based on the curved air guide plate;

[0063] Implementation method 1, refer to Figure 5 When there is only one arc-shaped air guide plate, the corresponding second air outlet hole 34 also has one, and an air duct is formed between the arc-shaped air guide plate and one side wall of the air cavity 33, and the entrance of the air duct completely covers the entrance of the air cavity 33;

[0064] Implementation method 2, refer to Figure 6 When there is only one arc-shaped air guide plate, there are also two corresponding air outlet holes 34 . One end of the arc-shaped air guide plate is located in the middle of the wind cavity 33 , so that the two sides of the arc-shaped air guide plate form two air ducts with the two sides of the wind cavity 33 , and the two air ducts correspond to the two air outlet holes 34 .

[0065] Implementation method three, refer to Figure 7 , n arc-shaped guide plates 35 are arranged in the air cavity 33, dividing the interior of the air cavity 33 into n+1 air ducts, and the end of each guide plate corresponds to the entrance of the air cavity 33. For example, there are three arc-shaped guide plates 35, and two air ducts are formed between the three arc-shaped guide plates 35. The first arc-shaped guide plate 35 and the third arc-shaped guide plate 35 respectively form air ducts with the two sides of the air cavity 33, that is, a total of four air ducts are formed, and each air duct corresponds to an air outlet 2 34.

[0066] Further, refer to Figure 4 A convex edge 37 is provided along the circumference direction of the second air outlet hole 34, and an embedding groove 16 is provided along the circumference direction of the first air outlet hole 13. The convex edge 37 fits with the embedding groove 16 to avoid air leakage.

[0067] In addition, the air outlet 13 gradually expands from the inside to the outside, and the high-speed airflow transitions from the narrow opening to the wide opening, which makes the airflow diffuse and covers a wider range.

[0068] In the present utility model embodiment, refer to Figure 13-Figure 15 , the air outlet 13 is horizontally or inclinedly arranged, so that the groove 2 15 forms a wind gathering area. Preferably, the groove 2 15 is in a "V" shape, and the air outlet 13 is arranged on an inclined surface. Regardless of which of the above-mentioned arrangements of the air outlet 13 is adopted, the two air flows generated have a faster flow rate, so that the groove 2 15 is in a low-pressure state; the following description will be made by taking the air outlet 13 as an example of being inclinedly arranged;

[0069] When the air outlet 13 outputs airflow, the two airflows will intersect. Since the two airflows have a relatively fast flow rate, the air pressure at the inner side of the two airflows is relatively low. At this time, air will be sucked in from the outside. Preferably, a part of the air will pass through the heating component 41 before entering the inner side of the two airflows, that is, the external air will first pass through the heating component 41 to be heated, thereby increasing the temperature of the inner side.

[0070] In the first embodiment, if the airflow is not heated, the temperature of the airflow blown out is at room temperature. Under the action of the wind gathering area, the temperature of the mixed airflow is increased, and the effect of drying the hair 7 with hot air is achieved while saving energy.

[0071] In the second embodiment, after several air flows are heated, the air flows blown out are not hot air, but the heating component 23 is usually heated by a heating wire, so the temperature of the air flow can usually reach 90°C-135°C, and energy loss may occur during the flow, so the temperature blown out will be slightly lower, and the temperature of the heating component 41 reaches 140°C-230°C when working. Under the action of the wind gathering zone, the external air is heated by the heating component 41 and then superimposed with the two air flows blown out, so that the maximum temperature of the wind gathering zone reaches 180°C, which greatly increases the temperature, thereby achieving a rapid drying effect.

[0072] Regardless of which of the above methods is used, when the external air enters the wind gathering area, it is attracted by the two airflows and moves in the direction of the two airflows, so that the hair 7 originally stacked together floats in the direction of the airflow, thereby separating the stacked hair 7 and straightening it along the direction of the airflow; preferably, if the airflow is sprayed out at an angle, it will eventually converge at an intersection and then flow in the vertical direction of the hair 7, that is, the direction of the airflow is the same as the vertical direction of the hair 7, further improving the hair straightening effect.

[0073] Preferably, the distance M between the outermost end of the heating component 41 and the air outlet 13 is ≤15mm. Of course, when the thickness of the hair 7 clamped by the clamping arm 11 and the clamping arm 2 12 is uniform and the pressure applied to the hair 7 is relatively large, there will be little or no external air passing through the heating component 41. However, the interior of the heating component 41 usually adopts PTC or MCH heating to conduct heat through the conductor, and its heat source is radiant. At the same time, since a part of the surface of one side of the heating component 41 is exposed at the bottom of the groove 2 15 and extends parallel to the bottom of the groove, and the air outlet 13 is arranged on the inclined surface of the groove 2 15, the distance M from the air outlet 13 to one side of the heating component 41 located at the bottom of the groove 2 15 is ≤15mm. The setting of this distance M can adsorb the heat source radiated from this side of the heating component 41 to the vicinity of the air outlet 13 to continue to act on the hair, thereby making full use of the heat that would otherwise be dissipated.

[0074] In the present utility model embodiment, refer to Figure 3 The clamp arm 11 and the clamp arm 2 12 have the same structure. The clamp arm 2 12 includes a shell 17. A heat insulation groove 18 is provided in the shell 17 at a position corresponding to the air outlet 13. The heat insulation groove 18 can reduce the heat transferred to the shell 17 and the outer shell of the clamp arm, and at the same time reduce the temperature of the outer surface of the clamp arm 11 and the clamp arm 2 12 to prevent excessive temperature from scalding people or causing discomfort to people.

[0075] The structure of the airflow generating unit 2 is described below. Figure 8-12 ;

[0076] Specifically, it includes a flexible three-way air duct 21. In this embodiment, the flexible three-way air duct 21 is integrally formed of a soft and high-temperature resistant (at least able to withstand a temperature of more than 230 degrees Celsius) material. One end of the flexible three-way air duct 21 forms an air inlet 211, and the other two ends form air outlets 212, which are symmetrically arranged at intervals and extend in the opposite direction to the air inlet 211; the two air outlets 212 are respectively connected to the wind cavities 33 of the two clamping arms; a mounting seat 22 is fixedly provided on the outer periphery of the air inlet 211, and a heating component 23 and a fan 24 are provided on the mounting seat 22. The relative positions of the air inlet 211, the heating component 23 and the fan 24 are fixed by the limitation of the mounting seat 22. Preferably, the air outlet 212 forms a rectangular flat air outlet, which is conducive to reducing the thickness of the clamping arm. A smaller thickness of the clamping arm is conducive to the clamping arm flipping or performing curling styling actions while clamping the hair 7.

[0077] When working, the fan 24 inhales external airflow and transports the external airflow to the heating component 23. The heating component 23 heats the airflow to increase the temperature of the airflow. After that, the airflow is input from the air inlet 211 of the flexible three-way air duct 21 after the temperature rises, and is divided into two air flows and output from the two air outlets 212 respectively. In this embodiment, the air inlet 211, the heating component 23 and the fan 24 are distributed in sequence and are coaxially arranged, which can reduce the resistance of the airflow as much as possible, reach the flexible three-way air duct 21 more directly, and reduce the generation of noise.

[0078] The utility model is provided with an independent heating component 23 between the flexible three-way air duct 21 and the fan 24, which can heat the airflow independently without being affected by other factors, making the use of the hair straightener more diverse. At the same time, the flexible three-way air duct 21, the heating component 23 and the fan 24 are formed into a standard installation module through the mounting seat 22, making assembly and application more convenient.

[0079] One embodiment of the mounting seat 22 of the utility model specifically includes a fixing ring 2211 and an arc-shaped mounting plate 2221. The fixing ring 2211 is adapted to the inlet shape of the air inlet portion 211 and is fixedly arranged on the inner wall thereof. The inlet shape of the air inlet portion 211 can be fixed by the setting of the fixing ring 2211, and will not be affected by the opening and closing of the hair straightener, so that the maximum air intake volume can be maintained. A plurality of positioning posts 2214 are arranged on the outer periphery of the fixing ring 2211. The extending portion of the positioning posts 2214 is connected to the arc-shaped mounting plate 2221. Of course, a second hole 214 corresponding to the positioning posts 2214 is arranged on the flexible three-way air duct 21 for the positioning posts 2214 to pass through. The two cooperate with each other to also play a positioning role. Preferably, when the arc-shaped mounting plate 2 When there is only one piece of 221, there are two positioning columns 2214, which are extended on the side close to one of the air outlets 212. When there are two arc-shaped mounting plates 2221, the two arc-shaped mounting plates 2221 can enclose the heating component 23 and the fan 24. In addition, there are four positioning columns 2214, which are extended on both sides of the two air outlets 212 respectively; the inner side of the arc-shaped mounting plate 2221 is fitted with the outer side of the air inlet 211, and the arc-shaped mounting plate 2221 is in a straight line extending shape, and forms a clamping state with the fixing ring 2211 on the outer wall of the air inlet 211, so that the arc-shaped mounting portion 2224 remains in a straight line with the entrance of the air inlet 211, providing a basis for the coaxial arrangement of the air inlet 211, the heating component 23 and the fan 24.

[0080] Furthermore, a flange 2215 is provided along the circumference direction of the fixing ring 2211, and a groove three 213 is provided on the inner side of the air inlet portion 211 for use therewith. The size of the inner cavity of the air inlet portion 211 should be slightly smaller than the outer diameter of the fixing ring 2211. During installation, the fixing ring 2211 is inserted into the air inlet portion 211 from the entrance by interference fit, and then the flange 2215 of the fixing ring 2211 is engaged with the groove three 213, so that the fixing ring 2211 and the air inlet portion 211 are firmly fixed to prevent falling off.

[0081] Furthermore, the fixing ring 2211 extends from the inlet of the air inlet portion 211 to the outside, and a boss 2227 is provided on the inner side of the arc-shaped mounting plate 2221 , and one side of the boss 2227 abuts against the edge of the fixing ring 2211 .

[0082] The utility model further explains the fixing ring 2211. A dividing strip 2212 is provided in the middle of the fixing ring 2211. The position of the dividing strip 2212 is integrated with the middle position of the two air outlets 212. The dividing strip 2212 divides the interior of the fixing ring 2211 into two hole positions 2213. The two hole positions 2213 respectively correspond to the air passages of the two air outlets 212. Before the airflow enters the air outlet 212, it is first cut by the dividing strip 2212 so as to be divided into two airflows which can directly enter the corresponding air passages, thereby reducing the generation of vortices in the air inlet 211 and improving the air outlet efficiency. Preferably, a curved surface design is adopted on the side of the dividing strip 2212 close to the heating component 23 so as to reduce the resistance of the airflow when it is divided, thereby making the airflow flow smoother.

[0083] In the embodiment of the utility model, a plurality of convex strips 2222 are provided on the outer side of the arc-shaped mounting plate 2221, and a card slot 2223 is formed between adjacent convex strips 2222. The card slot 2223 is engaged with a card block 1 (not shown) on an external shell 1 (not shown) to facilitate positioning during installation.

[0084] In one embodiment of the heating component 23 of the utility model, a bracket 231 is specifically included. The bracket 231 in this embodiment is composed of a plurality of high temperature resistant heat insulating mica sheets, which are connected together on one side and then spaced apart in a ring array. A heating wire (not shown) and a fixing member 232 are respectively wound around the bracket 231. The bracket 231 is provided with a plurality of fixing grooves (not shown) for fixing the winding of the heating wire. After the winding of the heating wire is completed, the space enclosed by the heating wire is smaller than the outer diameter of the bracket 231, that is, even if the bracket 231 is in contact with the arc-shaped mounting plate 2221, the heating wire will not contact with the arc-shaped mounting plate 2221, and will not cause damage to it; therefore, when the heating component 23 is installed, the bracket 231 is installed so that the outer periphery of the bracket 231 abuts against the inner side of the arc-shaped mounting plate 2221, thereby limiting its position;

[0085] The fixing member 232 is provided with a plurality of second "L"-shaped slots 233, which are engaged with the second block 234 on the second external shell body. A limiting slot 2226 engaged with the bracket 231 is provided on the inner side of the mounting seat 22. During installation, the position of the bracket 231 is limited by the limiting slot 2226. When it needs to be installed after the hair straightener is installed, the bracket 231 is fixed by the second block 234 in the second external shell body and the second slot 233 to complete the installation.

[0086] Furthermore, when there are two fixing members 232 , they are symmetrically mounted on both sides of the bracket 231 . At this time, a corresponding hole (not shown) is opened on the arc-shaped mounting plate 2221 for one of the fixing members 232 to pass through the second external shell for connection.

[0087] Furthermore, a limit block 235 is laterally extended from one side of the fixing member 232 close to the fan 24, and the limit block 235 can be inserted into the outer shell three;

[0088] It should be noted that the outer shell 1, outer shell 2 and outer shell 3 mentioned above can be a whole or separate components, but they are all parts of the hair straightener and are not limited here.

[0089] In the present invention, the arc-shaped mounting plate 2221 is formed with a mounting portion 2224 for fixing the fan 24 , and near the air inlet 36 of the fan 24 , the arc-shaped mounting plate 2221 is integrally formed with a honeycomb-shaped noise reduction net 2225 .

[0090] like Figure 13-Figure 15 As shown, a hair shaping curved surface 19 is formed on the other side of the outer surface of the clamp arm relative to the second groove 15, which is beneficial to the close-to-face curling of hair.
