[0036] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Combine the following Figure 1-Figure 7The hair straightening device 100 of the utility model is described. It should be noted that the hair straightening device 100 can help the user create an ideal hairstyle and achieve a straight hair effect, and the hair straightening device 100 can provide corresponding functions and assistance. When using the hair straightening device 100, the hair straightening device 100 can generate a high-speed hot air flow, and the hot air flow can evenly heat the hair to soften the hair. At the same time, the wind pressure difference formed by the high-speed wind can form a pulling force on the softened hair, and then the hair is straightened when the hair is heated and dried. When the user uses the hair straightening device 100, he only needs to place the hair in the working channel 121 to achieve the shaping and straightening of the hair. During the whole process of straightening the hair, the machine does not have substantial contact with the hair. The hair is wrapped by the air flow and provides pulling force, and finally presents a smooth and straight state. In addition, the hair straightening device 100 often has a variety of temperature settings to meet the needs of different hair qualities, provide hot air flows with different wind speeds, and reduce damage to the hair 160.

[0038] See also Figure 1 and Figure 4 As shown, the hair straightening device 100 may include a hand-held portion 110 , a first working portion 120 , and a second working portion 130 .

[0039] Specifically, the handheld portion 110 can be held by the user. The handheld portion 110 can be a part specially designed for the user to hold, and its shape, size and material are carefully designed to ensure that the user can feel comfortable when using it. When designing the handheld portion 110, ergonomic principles can be used to ensure that the user's hand can naturally adapt to the way the device is held, reduce hand fatigue, and improve the efficiency and accuracy of the operation. For example, the handheld portion 110 may include some raised or recessed designs to provide a better grip and anti-slip effect, or use soft materials to increase the comfort when holding.

[0040] In addition, if Figure 1 As shown, a control button 150 may be provided on the handheld portion 110 to facilitate the user to control the operation of the hair straightening device 100. The control button 150 may be a mechanical button or a touch button.

[0041] The first working part 120 and the second working part 130 can process the hair 160 so that the processed hair 160 can be straightened. Figure 1 and Figure 2 As shown, one end of the first working part 120 and one end of the second working part 130 are connected to the hand-held part 110, and a working channel 121 is defined between the second working part 130 and the first working part 120, and the hair 160 can be placed in the working channel 121. Figure 1As shown, the first working part 120 and the second working part 130 are fixedly connected via the hand-held part 110 , and the first working part 120 and the second working part 130 are arranged in parallel.

[0042] Combination Figure 3 and Figure 5 As shown, the channel wall of the working channel 121 includes at least one guiding slope 122, and at least one of the first working part 120 and the second working part 130 is provided with a working chamber 123 and an air outlet 124 connected to the working chamber 123. Under the guiding action of the guiding slope 122, the airflow in the working chamber 123 is suitable for flowing to the working channel 121 through the air outlet 124.

[0043] See also Figure 1 As shown, the working channel 121 is a semi-open structure, and the air outlet 124 extends along the length direction of the first working part 120, that is, the air outlet 120 is open to the semi-open space, which can concentrate on utilizing the speed and heat of the air flow to efficiently dry the hair.

[0044] Understandably, see Figure 6 As shown, when the airflow a in the working chamber 123 flows out through the air outlet 124, the airflow a flows in the working channel 121 under the guidance of the guide slope 122; and due to the flow of the airflow in the working channel 121, a negative pressure is generated on the outside of the working channel 121. Under the action of the negative pressure, the air outside the working channel 121 forms an airflow c and flows toward the working channel 121; the airflow a and the airflow c are mixed in the working channel 121 to form an airflow b, and the airflow b circulates in the working channel 121, which has a shaping effect on the hair 160.

[0045] It should also be noted that under the action of negative pressure, a large wind pressure difference is formed in the working channel 121, that is, the airflow b has a large pulling force, and the hair 160 is limited by the working channel 121 and blow-molded by the airflow b, so that the hair straightening device 100 has a straightening effect, thereby achieving the effect of straightening the hair 160.

[0046] See also Figure 1-Figure 4 As shown, the first working part 120 and the second working part 130 are arranged opposite to each other and form a U-shaped structure. The working channel 121 in the U-shaped structure can be used to place the hair 160, and the airflow flowing out of the air outlet 124 can be concentrated on the hair 160. By utilizing the speed and heat of the airflow, the more concentrated the wind force is, the greater the wind pressure difference formed thereby is, that is, the greater the pulling force is, thereby achieving the effect of straightening the hair 160.

[0047] In addition, when the first working part 120 and the second working part 130 both have a working chamber 123, an air inlet 111 can be provided on the handheld part 110, and the airflow enters the handheld part 110 through the air inlet 111, and is divided into two and enters the working chambers 123 in the first working part 120 and the second working part 130 respectively. The pressure of the airflow is enhanced in the working chamber 123, and the airflow is blown out through the air outlet 124. Since the airflow will flow into the working channel 121 through the air outlet 124, the speed and heat of the airflow can be concentrated at this time. The smaller the distance between the U-shaped structures, that is, the smaller the spacing of the working channels 121, the more concentrated the wind force, and the greater the wind pressure difference between the upper and lower parts of the wind nozzle formed thereby, that is, the greater the pulling force. However, in order to facilitate the placement of hair in the working channel, the distance between the U-shaped structures needs to be within a suitable range to meet the pulling force and facilitate the placement of hair, thereby achieving the effect of straightening hair 160. It should be noted that the airflow can heat the hair evenly, and at the same time, the high-speed airflow can form a pulling force on the hair, so that the hair can be straightened while being heated and dried, and the hair can be shaped. During the whole process of straightening the hair, the machine does not have substantial contact with the hair, and the hair is wrapped and provided with pulling force by the airflow, thereby protecting the hair. When the hair straightening device 100 is used as a hair dryer, the air outlet 124 can be aimed at the hair 160, and the high-speed and high-temperature air can quickly dry the hair 160.

[0048] According to the hair straightening device 100 of the embodiment of the utility model, by providing the guiding slope 122 in the working channel 121, when the airflow a in the working chamber 123 flows out through the air outlet 124, the airflow a flows in the working channel 121 under the guidance of the guiding slope 122; and due to the flow of the airflow in the working channel 121, a negative pressure is generated outside the working channel 121. Under the effect of the negative pressure, the air outside the working channel 121 forms an airflow c and flows toward the working channel 121. The airflow b circulates in the working channel 121, which has a shaping effect on the hair 160.

[0049] like Figure 1 As shown, according to some embodiments of the utility model, a plurality of guide plates 125 are provided in the air outlet 124, and the plurality of guide plates 125 are spaced apart along the length direction of the first working part 120. It should be noted that the guide plates 125 can not only make the airflow in the working chamber 123 flow out from the air outlet 124 evenly, but also the plurality of guide plates 125 divide the air outlet 124 into a plurality of sub-outlets, and the structure of the sub-outlets can construct a nozzle structure. When the airflow passes through the sub-outlets, the pressure of the airflow in the working chamber 123 is enhanced, and it can be sprayed into the working channel 121. The more concentrated the wind force is, the greater the wind pressure difference between the upper and lower wind nozzles formed thereby is, that is, the greater the pulling force is, so as to achieve the effect of straightening the hair 160. When used as a hair dryer, the air outlet 124 is aimed at the hair 160, and the high-speed and high-temperature wind can quickly dry the hair 160.

[0050] Further, the distance between any two adjacent guide plates 125 is L, and the value range of L is 2mm-10mm. In this way, the airflow can flow out evenly. In some preferred embodiments, the distance between the guide plates 125 can be 2mm, 4mm or 10mm, that is, L=2mm, or L=4mm, or L=10mm.

[0051] like Figure 1 As shown, according to some embodiments of the present invention, the direction of the airflow in the working channel 121 is perpendicular to the length direction of the first working part 120; the air outlet 124 is located at the upstream end of the airflow in the working channel 121. In this way, the airflow a flowing out of the air outlet 124 can flow more smoothly to the downstream end of the working channel 121, extending the contact length between the airflow a and the hair 160; in addition, by setting the air outlet 124 at the upstream end of the working channel 121, a negative pressure can be formed on the outside of the upstream end of the working channel 121, so that the airflow outside the working channel 121 can also enter the working channel 121, thereby making the wind force more concentrated, and the greater the wind pressure difference between the upper and lower wind nozzles, that is, the greater the pulling force, thereby achieving the effect of straightening the hair 160.

[0052] According to some embodiments of the present invention, see Figure 5 and Figure 7 As shown, at the upstream end of the airflow in the working channel 121, the width of the working channel 121 is L1, wherein the value range of L1 is 2mm-5mm. Preferably, L1 can be 2mm, 4mm or 5mm, that is, L1 = 2mm, or L1 = 4mm, or L1 = 5mm. According to some embodiments of the present invention, see Figure 6 and Figure 7 As shown, at the downstream end of the airflow in the working channel 121, the width of the working channel 121 is L2, wherein the value range of L2 is 5mm-10mm. Preferably, L2 can be 5mm, 8mm or 10mm, that is, L2 = 5mm, or L2 = 8mm, or L2 = 10mm. According to some embodiments of the present invention, see Figure 5 and Figure 7 As shown, the included angle θ between the guiding inclined surface 122 and the direction of the airflow in the working channel 121 is less than or equal to 25°, preferably, θ=30° or θ=35°.

[0053] In order to simplify the structure of the hair straightening device 100, according to some embodiments of the present invention, the housing of the first working part 120 or / and the housing of the second working part 130 are integrally formed with the housing of the handheld part 110. In other words, in some optional examples, the housing of the first working part 120 is integrally formed with the housing of the first working part 120; in some optional examples, the housing of the second working part 130 is integrally formed with the housing of the handheld part 110; in some optional examples, the housing of the first working part 120, the housing of the second working part 130 and the housing of the handheld part 110 are integrally formed. Further, the first working part 120 and the second working part 130 have the same structure.

[0054] In order to make the hair straightening device 100 have a heating function, in some embodiments of the present invention, see Figure 8 As shown, a mounting cavity and an air inlet 111 connected to the mounting cavity are provided in the handheld part 110, the mounting cavity is connected to the working cavity 123, and a heating element 140 is installed in at least one of the working cavity 123 and the mounting cavity. The heat released by the heating element 140 exchanges heat with the airflow, so that the airflow blown out from the air outlet 124 can be a high-temperature airflow, which can heat the hair 160, thereby achieving the purpose of drying the hair 160.

[0055] Combination Figure 8 As shown, there can be multiple air inlets 111, and the multiple air inlets 111 are arranged in an array, that is, the air inlets 111 are distributed in multiple rows and columns. Of course, the air inlets 111 can also be distributed in a mesh shape; or, the air inlets 111 are evenly distributed.

[0056] In some examples, hair straightening device 100 may be a hair straightening iron.
