In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0041] Combine the following Figures 1 to 6 The embodiment shown describes the technical solution of the utility model: wherein, Figures 1 to 4 As shown:

[0042] The embodiment of the utility model provides a hair straightener, comprising: a main body 1, a first detection module 3 and a clamping arm 2, wherein there are at least two clamping arms 2 connected to the main body 1, wherein at least one clamping arm 2 has an air duct 201, and an air outlet end of the air duct 201 is connected to a blowing cavity 202 located on the inner surface of the clamping arm 2, so that the airflow blown out along the blowing cavity 202 can act on the hair between the two clamping arms 2, achieving the effect of hot air drying hair or cold air setting hair, and a heating component is also provided on the clamping arm 2, so that the user can achieve the effects of drying hair and straightening hair through a high-temperature clamping plate.

[0043] A heater for heating air and a fan for sucking outside air into the air duct 201 of the clamping arm 2 are arranged in the main body 1. Naturally, an air inlet 101 is opened on the main body 1, and the air inlet 101 is connected with the air duct 201, and the air outlet 203 of the air duct 201 is connected with the blowing cavity 202, so that the air flow is blown out through the blowing cavity 202 and acts on the hair.

[0044] The first detection module 3 is arranged on the clamp arm 2 with the air duct 201, and is used at least to detect the humidity of the hair. Of course, the first detection module 3 can also be used to detect other parameters of the hair, such as the temperature of the hair, and control the hot air temperature and / or the temperature of the heating component of the hair straightener through the detected temperature value, so as to avoid the hair being damaged by the hair straightener being too hot. The shell 301 of the first detection module 3 is a square box body, which is installed in the middle of the clamp arm 2, and there is a partition inside the shell 301, and a vent is provided on the partition, and the partition divides the inner cavity of the square box body into a detection cavity 302 and an air intake cavity, and the air intake cavity is connected to the blowing cavity 202 through the air duct 303, that is, the detection cavity 302 is connected to the blowing cavity 202; the detection unit 304 is arranged in the detection cavity 302, and an air inlet hole 305 is provided on the cavity wall of the detection cavity 302; the setting direction of the air duct 303 is the same as that of the air duct The air outlet direction of the air outlet end 201 is consistent; thus, the Venturi effect can be realized. When high-speed wind blown out by the air duct 201 appears in the blowing chamber 202, negative pressure is formed around the shell 301, and the hair clamped by the clamp arm 2 is close to the first detection module 3, which can drive the air around the hair to enter the detection chamber 302 through the air inlet 305, so that the humidity of the hair can be measured, avoiding the influence of the heating component on the detection unit 304 due to high heat, and also avoiding direct contact humidity measurement of the hair. The air duct 303 is independent of the air duct 201 and is only connected to the blowing chamber 202, which can avoid the hot air in the air duct 201 from being directly blown into the detection chamber 302 to affect the detection result, which is conducive to ensuring the accuracy of humidity detection.

[0045] The hair straightener provided by the utility model further includes: a second detection module and a processing module, wherein the second detection module is at least used to detect the ambient humidity and is arranged on the main body 1; the processing module is electrically connected to the first detection module 3, the second detection module and the heating component respectively, and the processing module can at least control the operation of the heating component. It can be understood that the second detection module can be arranged at any part of the main body 1, as long as it can avoid the measurement range of the first detection module 3.

[0046] In this embodiment, the second detection module is arranged inside the air inlet 101 of the main body 1, so it is not shown in the drawing; the purpose of such arrangement is to accurately detect the ambient humidity, because if only a first detection module 3 for detecting hair humidity is arranged on the clamp arm 2, although its purpose is to detect the humidity of the hair, not all users will put the hair straightener on their hair as soon as the machine is turned on. At this time, the data detected by the first detection module 3 may only be the ambient humidity. Therefore, by arranging the above two detection modules, one of which is arranged in the working area to detect the hair humidity, and the other is arranged at the air inlet 101 to detect the ambient humidity, and the hair humidity is subtracted from the ambient humidity to obtain the detected humidity, the detection accuracy of the hair humidity can be improved, which is conducive to the processing module to more accurately control the hair straightener according to the detected humidity.

[0047] Furthermore, this embodiment also provides a control logic for automatically controlling the working mode of the heating component according to the detected humidity value:

[0048] 1. If the detected humidity is greater than 5%, that is, the difference between the hair humidity and the ambient humidity is greater than 5%, the hair humidity is high, and the hair straightener only dries the hair in dry mode. In order to speed up the hair drying efficiency, the heating component can start the low-temperature mode at this time. For example, heat the heating component for 15 seconds, so that the temperature of the heating component quickly rises to about 90°C. Through the relatively low heating temperature, the heating component can both assist the hot air in drying the hair and avoid the high-temperature heating component heating the over-wet hair, which will cause a squeak like a barbecue when used, or cause a lot of smoke from wet hair. It can also avoid the problem of too high a heating temperature damaging the hair. After the heating component is heated, it will continue to detect the hair humidity. The following three situations may occur in the subsequent detection:

[0049] ① If the detected humidity is still greater than 5%, heat the heating component for another 15 seconds, and restart the detection of hair humidity after heating is completed;

[0050] ② If the detected humidity is less than 5% and greater than -10%, and the hair humidity is close to the ambient humidity, the heating component will not be started, and the hair humidity will be detected again; at this time, the hair is relatively dry, and only hot air can be used to dry the hair;

[0051] ③If the detected humidity is less than or equal to -10%, when the humidity of the hair is low, the hair straightener enters the styling mode, and the heating component starts the corresponding high-temperature mode. At this time, the heating component can continuously heat to about 180°C, using high temperature to heat the hair to achieve styling effects such as straightening the hair.

[0052] 2. If the detected humidity is less than 5%, that is, the difference between the hair humidity and the ambient humidity is less than 5%, the heating component will not be started, and the hair humidity will be detected again. The following situations may occur in the subsequent detection:

[0053] ① If the detected humidity is greater than 5%, the increase in humidity means that the user had not put the hair into the machine during the last detection, but the hair has been put into the machine at this time, and the operation will be carried out according to the logic of point 1 above.

[0054] ② If the detected humidity is less than 5%, the heating component will not be started and the hair humidity will be detected again. This can avoid the situation where the heating component is turned on without putting the hair on the machine.

[0055] It can be understood that in other embodiments, the set value of the detected humidity that affects the control logic is not limited to 5% and -10%, and the set value can be adjusted according to different working conditions; and the control logic of the working mode of the hair straightener is not limited to the one described above. In other embodiments, the hair straightener can also control whether the high temperature mode of the heating component can be turned on or provide the humidity information of the hair to the user only by detecting the humidity value, and the user can choose to turn on the high temperature mode of the heating component.

[0056] According to the hair straightener provided by the utility model, Figure 3 As shown, there is a first distance between the detection cavity 302 and the clamp arm 2. The distance is flexibly adjusted according to the heat of the heating component or the size of the clamp arm 2, so that the detection cavity 302 is not affected by the heat of the heating component as much as possible. The first distance is usually greater than 15mm. In this embodiment, Figure 3 The example shows that the distance from the bottom end of the detection cavity 302 to the upper end surface of the clamp arm 2 is 16 mm, so that the detection unit 304 in the detection cavity 302 is away from the heating area of ​​the clamp arm 2, reducing the impact of the high temperature of the clamp arm 2 when working on the first detection unit 304, making the detection of the first detection unit 304 more accurate.

[0057] According to the hair straightener provided by the utility model, Figure 1 , Figure 5 and Figure 6 As shown, the heating assembly includes: a heat conductive sheet 5 and a heating unit 4, wherein the heat conductive sheet 5 is arranged on the inner surface of the clamp arm 2 having the blowing cavity 202, and the air passage 303 is hidden on the back of the heat conductive sheet 5, which is beneficial to improving the aesthetics of the clamp arm 2 and making full use of the installation space on the clamp arm 2; the heating unit 4 is arranged on the inner surface of the clamp arm 2 on the opposite side. At this time, the heating unit 4 is far away from the first detection module 3, and the heat generated will not be directly transferred to the first detection module 3.

[0058] In some embodiments, the thermal conductive sheet 5 can be an aluminum sheet or other metal material with good thermal conductivity, or a ceramic sheet, etc. The heating unit 4 can be a high-temperature co-fired ceramic heating sheet (HTCC), a positive temperature coefficient thermistor (PTC), etc., and PTC is preferred here.

[0059] According to the hair straightener provided by the utility model, Figure 3 and Figure 4As shown, the outlet end of the air duct 201 includes a plurality of air outlets 203 arranged side by side, and the air outlets 203 are all connected to the blowing chamber 202. A plurality of air guide plates are arranged below the air outlets 203, and two adjacent air guide plates correspond to one air outlet, so that the wind in the air duct 201 can be guided out along the direction of the air guide plates; but except for the air guide plate in the middle which is arranged in a vertical direction, the air guide plates on both sides thereof have an inwardly gathered slope, so that the extension lines of the air outlet directions of the plurality of air outlets 203 are inclined toward the middle, and the two opposite side walls of the blowing chamber 202 are arranged obliquely inward, thereby having a gathering effect on the blowing direction, so that the airflow can gather the hair to the middle when in use, making it more convenient for customers to stably clamp the hair through the clamp arm 2, and the operation is simple. It is also conducive to concentrating the wind force, which can better dry and smooth the hair.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
