The airflow generation part (2) has two output ends which are respectively communicated with a first clamping arm (11) and a second clamping arm (12). The first clamping arm (11) and the second clamping arm (12) are each provided with a hair straightening heating component (41). At least one first air outlet hole (13) is formed at the same side of each of the first clamping arm (11) and the second clamping arm (12). A second groove (15) is formed at the position close to first air outlet holes (13). The first air outlet holes (13) are horizontally or obliquely arranged, so that an air-gathering region is formed at the second groove (15).

DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0047] Please refer to FIG. 1-15;

[0048] The hair straightener has an air outlet function, which can quickly dry the hair 7, and specifically includes an air flow generating part 2, which has two output ends and is communicated with the clip arm one 11 and the clip arm two 12. The main body to be protected in the present application is a hair straightener. According to the use mode of the prior art hair straightener, the hair 7 is clamped by the clip arm one 11 and the clip arm two 12, and the hair 7 is heated at the same time, so as to soften the hair 7 and achieve the purpose of styling. Therefore, one or both of the clip arm one 11 and the clip arm two 12 in the present embodiment have a heating function, which can heat the hair 7. In the present embodiment, the straightening heating assembly 41 in the clip arm is not improved, so the structure in the prior art can be used. In addition, an elastic part 42 can be arranged between the straightening heating assembly 41 and the clip arm to realize the floating of the straightening heating assembly 41 and avoid clamping the hair 7;

[0049] In the embodiment of the present application, referring to Figs. 13-15, the air outlet hole 13 is horizontally or obliquely arranged, so that the recess 15 forms a wind gathering area. Preferably, the recess 15 is in the shape of a "V", and the air outlet hole 13 is arranged on the inclined surface. Regardless of which arrangement is adopted for the air outlet hole 13, the two air flows generated have a relatively high speed, so that the recess 15 is in a low pressure state. The following will be described by taking the oblique arrangement of the air outlet hole 13 as an example.

[0050] When the air outlet hole 13 outputs the air flow, the two air flows intersect. Since the two air flows have a relatively high speed, the air pressure at the inner side of the two air flows is relatively low. At this time, air is sucked from the outside. Preferably, part of the air passes through the heating assembly 41 before entering the inner side of the two air flows, i.e. the outside air is heated by the heating assembly 41 first, so that the temperature at the inner side is increased.

[0051] In the first embodiment, if the air flow is not heated, the temperature of the blown air flow is normal. Under the action of the wind gathering area, the temperature of the mixed air flow is increased. On the premise of saving energy, the effect of drying the hair 7 by hot air is achieved.

[0052] In the second embodiment, if the air flow is heated, the blown air flow is hot air. However, the heating assembly 23 usually adopts a heating wire to heat. Therefore, the temperature of the air flow usually reaches 90-135℃. Energy loss may occur during the flow. Therefore, the temperature of the blown air flow is slightly lower. The temperature of the heating assembly 41 reaches 140-230℃ when it works. Under the action of the wind gathering area, the outside air is heated by the heating assembly 41, and is superimposed with the blown two air flows. The maximum temperature of the wind gathering area reaches 180℃, so that the temperature is greatly increased, thereby achieving the effect of rapid drying.

[0053] Of course, when the hair 7 clamped by the clamping arm 11 and the clamping arm 12 has a uniform thickness, and the pressure applied to the hair 7 is relatively large, the outside air passing through the heating assembly 41 is very small or even none. However, the heating assembly 41 usually adopts PTC or MCH heating to conduct heat. The heat source is radiative. Since one side of the heating assembly 41 is exposed to the bottom of the recess 15 and extends in parallel along the bottom, and the air outlet hole 13 is arranged on the inclined surface, the distance M from the air outlet hole 13 to the side of the heating assembly 41 located at the bottom of the recess 15 is ≤15mm. The distance M can absorb the heat source radiated from this side of the heating assembly 41 to the vicinity of the air outlet hole 13 to continue to act on the hair, so that the originally lost heat is fully utilized.

[0054] No matter which way is adopted, in the process of the air entering the wind gathering area, the air is attracted by the two air flows and moves to the direction of the two air flows, so that the hair 7 originally stacked together is blown along the direction of the air flow, so that the hair 7 stacked together is separated and straight along the direction of the air flow; preferably, if the air flow is inclined to be sprayed, the air flow will finally flow along the vertical direction of the hair 7 after converging at a cross point, that is, the direction of the air flow is the same as the vertical direction of the hair 7, further improving the straightening effect.

[0055] Preferably, the distance between the outermost end of the heating assembly 41 and the air outlet hole one 13 is ≤15mm, when the hair 7 clamped by the clamping arm one 11 and the clamping arm two 12 is uniform in thickness, and the pressure applied to the hair 7 is larger, the external air passing through the heating assembly 41 will be very little or even none, but the internal part of the heating assembly 41 is usually heated by PTC or MCH to conduct heat, and the heat source is radiative, the groove bottom of the groove two 15 is composed of the surface of the heating assembly 41 side exposed in the groove two, and the surface constituting the groove bottom extends longitudinally in a straight line, and the air outlet hole one 13 is arranged on the inclined surface of the groove two 15, and the distance M from the air outlet hole one 13 to the side of the heating assembly 41 located at the groove bottom of the groove two 15 is ≤15mm, the setting of the distance M can absorb the heat source radiated from this side of the heating assembly 41 to the vicinity of the air outlet hole one 13 to continue to act on the hair, and fully utilize the heat originally lost.

[0056] In the embodiment of the application, referring to FIG. 3, the clamping arm one 11 and the clamping arm two 12 are the same in structure, the clamping arm two 12 comprises a shell 17, and the shell 17 is provided with a heat insulation groove 18 corresponding to the position of the air outlet hole one 13, so that the heat is less transmitted into the shell 17 and the outer shell of the clamping arm, and the temperature of the outer surface of the clamping arm one 11 and the clamping arm two 12 is reduced to prevent scalding or discomfort of people caused by too high temperature.

[0057] When the unfolding rotation angle of the first clamping arm 11 and the second clamping arm 12 is not large enough, it will cause the problem of difficult hair entering, therefore, the present application is combined at the end of the first clamping arm 11 and the second clamping arm 12 to form a "V"-shaped groove 14, when the user uses, the hair 7 enters from the end face, the "V"-shaped groove 14 can play a guiding role to guide the hair 7 to the middle position of the first clamping arm 11 and the second clamping arm 12; and in the process of the hair 7 entering the straightening area between the first clamping arm 11 and the second clamping arm 12, the edge position of the first clamping arm 11 and the second clamping arm 12 may cause obstruction to the hair 7, so that the hair 7 appears stacking and difficult to arrange in the process of entering the straightening area, therefore, at least the same side of the first clamping arm 11 and the second clamping arm 12 is combined to form a groove 15 in the embodiment, the groove 15 is opened to form an empty position on the side of the first clamping arm 11 and the second clamping arm 12, which will not hinder the entering of the hair 7, the present application is combined with the groove 14 and the groove 15 to form an "L"-shaped hair entering position in smooth transition, so that the hair 7 can enter the hair straightener more smoothly, to improve the user experience.

[0058] It should be noted that the groove 14 and the groove 15 are connected, that is, smooth transition, when used, the hair 7 will enter the straightening area towards the groove 14, and also towards the smooth transition of the groove 14 and the groove 15.

[0059] There is another way of using, the user can also directly put the hair 7 into the groove 15, the other side of the groove 15 is worn out, which provides more use options for the customer.

[0060] In addition, the groove 15 is only arranged on one side of the first clamping arm and the second clamping arm, and the other side of the first clamping arm 11 and the second clamping arm 12 is a hair styling curved surface 19, the product is a hair care and styling tool, in addition to straightening, it can also provide curling function, after the hair 7 is clamped by the first clamping arm 11 and the second clamping arm 12, the hair straightener is turned over, the hair will be bent along the hair styling curved surface 19, so as to achieve the purpose of curling.

[0061] Further, the groove 14 and the groove 15 are connected, that is, smooth transition, when used, the hair 7 will enter the straightening area towards the groove 14, and also towards the smooth transition of the groove 14 and the groove 15.

[0062] Preferably, the edge position of the first clamp arm 11 and the second clamp arm 12 is arc design b, where the arc design position specifically refers to the position corresponding to the straightening area, because during the straightening operation, the straightener is often not in line with the hair 7, so the hair 7 will interfere with the edge position of the first clamp arm 11 or the second clamp arm 12, when the edge position is set in a straight line, the contact area with the hair 7 is small, and relative movement can cause damage to the hair 7, so the arc design not only increases the contact area, but also makes the movement smoother with less resistance.

[0063] Regarding the specific structure of the air cavity 33, for example, refer to the relevant description of "CN117958540A - a hair dryer", the airflow passes through the heating assembly 41 and then blows out from the air outlet; in this embodiment, the air cavity 33 and the heating assembly 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, as shown in FIG. 4, the box body 3 is provided with an air outlet two 34 connected with the air outlet one 13, which can avoid the problem of gas leakage causing noise and air outlet not smooth, in addition, the airflow generating part 2 has a heating function, that is, the heating assembly 41 in the first clamp arm 11 and the second clamp arm 12 are independent of each other, and the airflow can also be heated to a higher temperature without passing through the straightening heating assembly 41 to dry the hair 7;

[0064] In addition, the air outlet of the air duct and the straightening heating assembly 41 in the present application are separated, so that the heat of the straight heating assembly 41 is not lost during the air output to the outside, so that the heating temperature of the straightener is more stable during the heating and care of the hair 7, and the independent heating of the airflow makes the temperature of the airflow more stable;

[0065] Further, the straightener should be provided with a controller, for example, a plurality of adjustment gears can be provided in the controller for controlling the airflow temperature of the airflow generating part 2, the user can select the corresponding gear according to the preference, that is, the temperature of the hot air blown out is controlled, without affecting the heating assembly 41, realizing temperature adjustment, or the heating assembly 41 can be turned off, the user can choose to use the blowing function alone, at this time the hair still can produce hot air, meet the different needs of the user.

[0066] Preferably, the box body 3 includes an upper shell 31 and a lower shell 32, and the upper shell 31 and the lower shell 32 are provided with concave-convex structures 38 at the edges for fitting connection, which can effectively play a sealing effect, of course, sealing gaskets or the like can be provided in position to increase the sealing property.

[0067] In actual production, the position of the air outlet hole 13 can be adjusted, and the box body 3 is fixedly installed in the shell. In order to connect the air outlet hole 13 and the air outlet hole 34, in the embodiment, the air outlet hole 34 arranged on one side of the box body 3 is lowered to be consistent with the height of the air outlet hole 13 to realize installation, and the position close to the air outlet hole 34 on the bottom surface of the lower shell 32 is a transition inclined arc surface a, so that the airflow flows smoothly, as shown in FIGS. 13-15. At the same time, the position close to the air outlet hole 34 on the bottom surface of the lower shell 32 is a transition inclined arc surface a, which cooperates with the form of the middle high and the two sides low of the heating assembly 41, the space is borrowed compactly and reasonably, which is beneficial to reduce the size of the whole straightening iron.

[0068] In the embodiment of the present application, the length of the box body 3 is equal to or greater than three times the width, the height is equal to or less than half the width, and the thickness of the heating assembly 41 is approximately equal to the thickness of the box body 3. The overall volume of the clamp arm can be reduced, and the area of the heating area of the heating assembly 41 can be ensured. The heat-conducting profile of the outer surface of the heating assembly 41 is usually cut from aluminum, and the overall shape is a rectangular sheet cube. The overall cooperation of the box body 3 is also a rectangular sheet cube, and the two are stacked one on top of the other. Therefore, the rectangular sheet cube shape of the two can reduce the overall thickness of the clamp arm, and the area of the heating area of the heating assembly 41 can be ensured. If the thickness of the clamp arm is too large, it will affect the appearance and cause the overall impression of the straightening iron to be heavy, and it will also affect the curling styling function of the straightening iron.

[0069] At least one arc-shaped flow guide plate 35 is arranged in the air cavity 33 to divide the air cavity 33 into at least one air duct. In order to cooperate with the heating assembly 41, the air cavity 33 is designed in a rectangular shape. When outputting airflow, the entire space needs to be filled, at which time the airflow will be subjected to a large resistance, which will not only cause the air outlet to be not smooth, but also cause a large noise. Therefore, the arc-shaped flow guide plate 35 is arranged to enable the airflow to smoothly change the angle and reduce the resistance, so as to solve the problems of noise and air outlet not smooth.

[0070] There are three embodiments based on the arc-shaped air guide plate;

[0071] In the first embodiment, referring to FIG. 5, when there is only one arc-shaped air guide plate, the corresponding air outlet hole 34 also has one. The arc-shaped air guide plate and one side wall of the air cavity 33 form an air duct, and the inlet of the air duct fully covers the inlet of the air cavity 33.

[0072] In the second embodiment, referring to FIG. 6, when there is only one arc-shaped air guide plate, the corresponding air outlet hole 34 also has two. One end of the arc-shaped air guide plate is located at the middle position of the air cavity 33, so that the two sides of the arc-shaped air guide plate form two air ducts with the two sides of the air cavity 33, respectively, and the two air ducts correspond to the two air outlet holes 34, respectively.

[0073] In the third embodiment, referring to FIG. 7, the wind cavity 33 is provided with n arc-shaped flow guides 35, which divide the wind cavity 33 into n+1 wind channels. The end of each flow guide corresponds to the inlet of the wind cavity 33. For example, the wind cavity 33 is provided with three arc-shaped flow guides 35, which form two wind channels. The first and third arc-shaped flow guides 35 form wind channels on both sides of the wind cavity 33, i.e., a total of four wind channels are formed, and each wind channel corresponds to an air outlet hole 34.

[0074] Further, referring to FIG. 4, the air outlet hole 34 is provided with a convex edge 37 along the circumferential direction, and the air outlet hole 13 is provided with an embedded groove 16 along the circumferential direction. The convex edge 37 is fitted with the embedded groove 16 to avoid air leakage.

[0075] In addition, the air outlet hole 13 gradually expands from the inside to the outside, and the high-speed airflow transitions between the narrow opening and the wide opening, which makes the airflow spread out and covers a wider range.

[0076] Next, the structure of the airflow generating part 2 will be described with reference to FIGS. 8-12.

[0077] Specifically, the flexible three-way air duct 21 is integrally formed of a soft material. One end of the flexible three-way air duct 21 forms an air inlet part 211, and the other two ends form air outlet parts 212, which are symmetrically arranged and extend in opposite directions relative to the air inlet part 211. The two air outlet parts 212 are connected to the wind cavities 33 of the two clamping arms, respectively. An installation seat 22 is fixedly arranged on the outer periphery of the air inlet part 211. A heating assembly 23 and a fan 24 are arranged on the installation seat 22. The relative positions of the air inlet part 211, the heating assembly 23, and the fan 24 are fixed by the installation seat 22. Preferably, the air outlet parts 212 form rectangular flat air outlet holes, which are beneficial to reducing the thickness of the clamping arms. A smaller thickness of the clamping arms is beneficial to the clamping arms to clamp the hair 7 while performing a hair flipping or curling action.

[0078] In operation, the fan 24 inhales external airflow and delivers the external airflow to the heating assembly 23. The heating assembly 23 heats the airflow to increase the temperature of the airflow. After the temperature of the airflow is increased, the airflow is input from the air inlet part 211 of the flexible three-way air duct 21 and is divided into two airflows which are output from the two air outlet parts 212, respectively.
