[0002] A hair straightener with a blow-drying function is one of the more mainstream hair care tools at present. In a hair straightener with a hot air function, the airflow usually needs to pass through a heating plate, and the heat of the heating plate is used to heat the airflow. For example, in the Chinese patent document "CN117958540A, a hair straightener with a blower", in a specific working process, the fan blades are driven by a motor to rotate and the heating element generates heat to blow hot air out from the first strip-shaped air outlet. When the hair is clamped by the clamping strip through the opposite movement of the hair clamping plates, the hair can be heated;

[0003] There are the following problems in relying on the heating element in the hairpin plate for heating:

[0004] 1. The temperature of the airflow is unstable and cannot be adjusted.

[0005] 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;

[0006] 3. When the blown airflow needs to be heated, the heating element must be turned on and cannot be operated alone, resulting in energy waste.

[0007] Based on the above problems, an integrated hot air supply component independent of the hair clamping plate is proposed. Utility Model Content

DETAILED DESCRIPTION

[0030] 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.

[0031] Please refer to Figure 1-5 ;

[0032] The hot air supply structure of the utility model is applied to a hair straightener, and has an independent hot air forming function, and does not need to be heated by the heating element in the clamp arm, so as to achieve the effect of independent use; specifically, it comprises a flexible three-way air duct 1, in this embodiment, the flexible three-way air duct 1 is formed in one piece by a soft and high temperature resistant material, one end of the flexible three-way air duct 1 forms an air inlet 11, and the other two ends form air outlets 12, which are arranged symmetrically at intervals and extend in the opposite direction relative to the air inlet 11; the two air outlets 12 are respectively connected to the air cavities of the two clamp arms; a mounting seat 2 is fixedly provided at the periphery of the air inlet 11, and a heating component 3 and a fan 4 are provided on the mounting seat 2, and the relative positions of the air inlet 11, the heating component 3 and the fan 4 are fixed by the limitation of the mounting seat 2, preferably, the air outlet 12 forms a rectangular flat air outlet, and the three-way air duct 1 is made of high temperature resistant material, and the rectangular flat air outlet is conducive to reducing the thickness of the clamp arm, and the smaller thickness of the clamp arm is conducive to the clamp arm flipping or performing a curling styling action while clamping the hair.

[0033] When working, the fan 4 inhales external airflow and transports the external airflow to the heating component 3. The heating component 3 heats the airflow to increase the temperature of the airflow. After that, the airflow is input from the air inlet 11 of the flexible three-way air duct 1 after the temperature rises, and is divided into two airflows and output from the two air outlets 12 respectively. In this embodiment, the air inlet 11, the heating component 3 and the fan 4 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 1 more directly, and reduce the generation of noise.

[0034] When the hot air supply described in the utility model is applied to a hair straightener, the air duct for air flow output is separated from the hair straightener heating element, that is, the air flow does not contact the hair straightener heating element, so that the heat of the hair straightener heating element 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 hair, and at the same time, an independent heating component 3 is used to heat the air flow, so that the temperature of the air flow is more stable;

[0035] 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 temperature of the heating component 3. When in use, the user can select the corresponding gear according to preference, thereby controlling the temperature of the heating component 3, that is, the temperature of the hot air blown out is controlled without affecting the hair straightening heating element, thereby achieving temperature adjustment. Alternatively, the hair straightening heating element can be turned off, and the user can choose to use a separate blowing function. At this time, the heating component 3 can still operate to achieve the blowing of hot air to meet the different needs of users.

[0036] The utility model is provided with an independent heating component 3 between the flexible three-way air duct 1 and the fan 4, 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, a standard installation module is formed by the mounting base 2, the flexible three-way air duct 1, the heating component 3 and the fan 4, making assembly and application more convenient.

[0037] One embodiment of the mounting base 2 of the present invention is shown in FIG. Figure 2 and Figure 5, specifically comprising a fixing ring 21 and an arc-shaped mounting plate 22. The fixing ring 21 is adapted to the inlet shape of the air inlet portion 11 and is fixedly arranged on the inner wall thereof. The inlet shape of the air inlet portion 11 can be fixed by the setting of the fixing ring 21, 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 23 are arranged on the outer periphery of the fixing ring 21. The extending part of the positioning posts 23 is connected to the arc-shaped mounting plate 22. Of course, a hole 14 corresponding to the positioning posts 23 is arranged on the flexible three-way air duct 1 for the positioning posts 23 to pass through. The two cooperate with each other to also play a positioning role. Preferably, when there is only one arc-shaped mounting plate 22, There are two positioning columns 23, which extend out from one side close to one of the air outlets 12. When there are two arc-shaped mounting plates 22, the two arc-shaped mounting plates 22 can enclose the heating component 3 and the fan 4. In addition, there are four positioning columns 23, which extend out from the two sides of the two air outlets 12 respectively; the inner side of the arc-shaped mounting plate 22 is fitted with the outer side of the air inlet 11, and the arc-shaped mounting plate 22 is in a straight line extending shape, forming a clamping state with the fixing ring 21 on the outer wall of the air inlet 11, so that the arc-shaped mounting portion 281 remains in a straight line with the entrance of the air inlet 11, providing a basis for the coaxial arrangement of the air inlet 11, the heating component 3 and the fan 4.

[0038] Further, refer to Figure 5 A flange 24 is provided along the circumference direction of the fixing ring 21, and a groove 13 is provided on the inner side of the air inlet portion 11 for use therewith. The inner cavity size of the air inlet portion 11 should be slightly smaller than the outer diameter of the fixing ring 21. During installation, the fixing ring 21 is inserted into the air inlet portion 11 from the entrance by interference fit, and then the flange 24 of the fixing ring 21 is engaged with the groove 13, so that the fixing ring 21 and the air inlet portion 11 are firmly fixed to prevent falling off.

[0039] Further, refer to Figure 1 The fixing ring 21 extends from the entrance of the air inlet 11 to the outside, and a step 25 is provided on the inner side of the arc-shaped mounting plate 22 , and one side of the step 25 abuts against the edge of the fixing ring 21 .

[0040] The utility model further explains the fixing ring 21. A dividing strip 261 is provided in the middle of the fixing ring 21. The position of the dividing strip 261 is integrated with the middle position of the two air outlets 12. The dividing strip 261 divides the interior of the fixing ring 21 into two hole positions 262. The two hole positions 262 respectively correspond to the air passages of the two air outlets 12. Before the airflow enters the air outlet 12, it is first cut by the dividing strip 261 to be divided into two airflows, which can directly enter the corresponding air passages, reduce the generation of vortices in the air inlet 11, and improve the air outlet efficiency. Preferably, the side of the dividing strip 261 close to the heating component 3 adopts an arc surface design to reduce the resistance of the airflow when it is divided, so that the airflow flows more smoothly.

[0041] In the present utility model embodiment, refer to Figure 3 A plurality of convex strips 271 are provided on the outer side of the arc-shaped mounting plate 22, and a card slot 272 is formed between adjacent convex strips 271. The card slot 272 is engaged with a card block 1 (not shown) on an external shell 1 (not shown) to facilitate positioning during installation.

[0042] In one embodiment of the present invention regarding the heating component 3, refer to Figure 2 and Figure 4 , specifically including a bracket 31. The bracket 31 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 32 are respectively wound around the bracket 31. The bracket 31 is provided with a plurality of fixing grooves (not shown) for fixing the winding of the heating wire. After the heating wire is wound, the space enclosed by the heating wire is smaller than the outer diameter of the bracket 31. That is to say, even if the bracket 31 is in contact with the arc-shaped mounting plate 22, the heating wire will not contact with the arc-shaped mounting plate 22 and will not cause damage to it. Therefore, when the heating component 3 is installed, the bracket 31 is installed so that the outer periphery of the bracket 31 abuts against the inner side of the arc-shaped mounting plate 22, thereby limiting its position.

[0043] Reference Figure 4 The fixing member 32 is provided with a plurality of "L"-shaped card slots 33, which are engaged with the card blocks 342 on the external shell 341. A limiting slot 29 engaged with the bracket 31 is provided on the inner side of the mounting seat 2. During installation, the position of the bracket 31 is limited by the limiting slot 29. When it needs to be installed after the hair straightener is installed, the card blocks 342 in the external shell 341 and the card slots 33 are fixed to complete the installation.

[0044] Furthermore, when there are two fixing members 32 , they are symmetrically mounted on both sides of the bracket 31 . At this time, corresponding holes (not shown) are opened on the arc-shaped mounting plate 22 for one of the fixing members 32 to pass through the second external shell 341 for connection.

[0045] Furthermore, a limit block 35 is laterally extended from one side of the fixing member 32 close to the fan 4, and the limit block 35 can be inserted into the outer shell 3 36;

[0046] It should be noted that the outer shell 1, the outer shell 2 341 and the outer shell 3 36 mentioned above can be a whole or separate components, but they are all parts of the hair straightener and are not limited here.

[0047] In the present utility model, reference Figure 2 The arc-shaped mounting plate 22 is formed with a mounting portion 281 for fixing the fan 4. Near the air inlet of the fan 4, the arc-shaped mounting plate 22 is integrally formed with a honeycomb-shaped noise reduction net 282.
