DETAILED DESCRIPTION

[0029] 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.

[0030] Please refer to Figure 1-9 ;

[0031] The hot air deflector box described in the utility model is arranged in the clamp arm of the hair straightener to form an independent wind chamber, and has a sealing and fixed direction deflection function for the airflow. At the same time, when there is hot air in it, it can reduce the heat diffusion to the shell of the hair straightener, avoid the risk of high temperature burns of the user or improve the comfort of the user. It specifically includes a box body 11. The box body 11 in this embodiment has an air inlet 14. Except for the air inlet 14 and the second air outlet 12, the other positions are all closed, and its inner cavity forms a wind chamber. The air inlet 14 is connected to the airflow generating component in the hair straightener. At least one second air outlet 12 is provided on one side of the box body 11. At least one arc-shaped air guide plate 13 is provided in the box body 11. One end of the arc-shaped air guide plate 13 corresponds to the air inlet 14, and the other end extends or is connected to one side of the box body 11, so as to divide the box body 11 into at least one air duct 15;

[0032] The shape of the wind chamber enclosed in the prior art is not fixed, 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, an arc-shaped air guide plate 13 is provided to enable the airflow to smoothly change angles and reduce its resistance, thereby solving the problems of noise and unsmooth air output.

[0033] There are three implementation methods based on the arc-shaped air guide plate 13;

[0034] Implementation method 1, refer to Figure 3When there is only one arc-shaped air guide plate 13, the corresponding air outlet hole 2 12 also has one, and an air duct 15 is formed between the arc-shaped air guide plate 13 and one side wall of the air cavity, and the entrance of the air duct 15 completely covers the air inlet 14 of the air cavity;

[0035] Implementation method 2, refer to Figure 4 When there is only one arc-shaped air guide plate 13, there are two corresponding air outlet holes 12. One end of the arc-shaped air guide plate 13 is located in the middle of the wind cavity, so that the two sides of the arc-shaped air guide plate 13 form two air ducts 15 with the two sides of the wind cavity respectively, and the two air ducts 15 correspond to the two air outlet holes 12 respectively.

[0036] Implementation method three, refer to Figure 5 , n arc-shaped air guide plates 13 are arranged in the air cavity, dividing the interior of the air cavity into n+1 air ducts 15, and the end of each air guide plate corresponds to the entrance of the air cavity. For example, there are three arc-shaped air guide plates 13, and two air ducts 15 are formed between the three arc-shaped air guide plates 13. The first arc-shaped air guide plate 13 and the third arc-shaped air guide plate 13 respectively form air ducts 15 with the two sides of the air cavity, that is, a total of four air ducts 15 are formed, and each air duct 15 corresponds to an air outlet 12.

[0037] Further, refer to Figure 6 and Figure 7 The box body 11 is installed in the clamp arm shell 31, and an air outlet hole 1 32 corresponding to the air outlet hole 2 12 is provided on one side of the clamp arm shell 31, and a groove 33 is provided at the position of the air outlet hole 1 32. A convex edge 16 is provided along the circumference direction of the air outlet hole 2 12 on the outside of the box body 11, and the convex edge 16 is embedded in the groove 33 to avoid air leakage; the air outlet hole 2 12 can also directly pass through the air outlet hole 1 32 to directly transport the airflow to the outside.

[0038] In addition, the air outlet 1 32 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.

[0039] In the embodiment of the utility model, the box body 11 is in the shape of a rectangular sheet, and a ironing plate 2 having a shape adapted thereto is disposed below the box body 11. The ironing plate 2 is usually punched out of an aluminum profile and is generally in the shape of a rectangular sheet. Therefore, it can be understood that the box body 11 is in the shape of a rectangular sheet in order to match the ironing plate 2 which is also in the shape of a rectangular sheet. At the same time, the second air outlet 12 is evenly distributed along the length direction of the box body 11, that is, extends along the length direction of the ironing plate 2, so that the hair clamped and subjected to the straightening treatment can be covered by the blown airflow, thereby improving the effect of smoothing or drying the hair.

[0040] Moreover, the box body 11 is in the shape of a rectangular sheet, which can avoid increasing the thickness of the hair straightener, so that the hair straightener can improve the wind output effect while ensuring the thickness of the hair straightener to facilitate turning over or curling the hair during use.

[0041] In this embodiment, the ironing board 2 is movably mounted on the bottom surface of the clamping arm housing 31, and an elastic member 4 is provided between the box body 11 and the ironing board 2. The elastic member 4 can be provided to allow the ironing board 2 to float, thereby preventing the hair from being clamped when clamped, thereby causing discomfort to the user.

[0042] In the present utility model, reference Figure 2 The box body 11 includes an upper shell 111 and a lower shell 112. The edges of the upper shell 111 and the lower shell 112 are provided with concave and convex steps 113 for fitting connection, which can effectively achieve a sealing effect. Of course, a sealing gasket can be provided at the right position to increase its sealing performance.

[0043] In actual production, the position of the air outlet 1 32 will be adjusted, and the box body 11 is fixedly installed in the shell. In order to connect the air outlet 1 32 with the air outlet 2 12, in this embodiment, the air outlet 2 12 arranged on one side of the box body 11 is moved down to keep the same height with the air outlet 1 32 to achieve installation, and the bottom surface of the lower shell 112 near the air outlet 2 12 is an inclined arc transition a, so that the air flow is smooth. At the same time, the bottom surface of the lower shell 112 near the air outlet 2 12 is an inclined arc surface a, which is matched with the shape of the ironing board 2 that is high in the middle and low on both sides. The space is borrowed compactly and reasonably, which is conducive to reducing the size of the overall straightener.

[0044] In the embodiment of the utility model, the length L of the box body 11 is ≥ three times the width W, the thickness D is ≤ one half of the width W, the thickness H of the ironing plate 2 is approximately equal to the thickness D of the box body 11, the thickness of the clamping arm can be reduced, and the area of ​​the heating zone of the ironing plate 2 can be ensured. At the same time, the thickness of the hair straightener is ensured to facilitate the flipping or curling function 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 at a time.
