[0017] In order to allow those skilled in the art to better understand the aspects of the present application, the following clearly and completely describes the technical aspects of the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all embodiments. Based on the embodiments of the present application, other embodiments obtained by those skilled in the art without paying creative labor shall all fall within the protection scope of the present application.

[0018] Hereinafter, the technical aspects of the embodiments of the present application will be clearly and completely described with reference to the drawings of the embodiments of the present application.

[0019] The hair styling device of the related art usually has a multi-layer housing, and a heat insulating material or an air layer is provided between the multi-layer housings, so as to reduce the temperature of the inner housing from being conducted to the outer housing. However, in this manner, the overall size of the hair styling device becomes too thick, which affects the user's experience. Some hair styling devices try to avoid the overall size of the hair styling device from becoming too thick by reducing the thickness of the multi-layer housing. In this case, the heat insulating material or the air layer provided between the multi-layer housings must also be thin accordingly, but the thin heat insulating material or the air layer will result in poor heat insulating effect, and will not be able to effectively reduce the temperature of the inner housing from being conducted to the outer housing.

[0020] The present invention provides a hair styling device 100, which can blow air onto a user's hair, straighten the hair, etc., so as to meet the usage needs of users in various situations.

[0021] 1 to 5, in some embodiments, the hair styling device 100 includes a housing 11, an air blowing passage 12, a heat dissipation passage 13, a driving member 14, and a heating member 15, and the housing 11 is provided with a handle portion 111 and an actuating portion 112 connected to each other, and the housing 11 includes an outer shell 113 and an inner shell 114, and the outer shell 113 is surrounded by the outer periphery of the inner shell 114. Here, the actuating portion 112 refers to a portion that can accommodate hair and can blow hot air to dry and straighten the hair, and the handle portion 111 may refer to a portion other than the actuating portion 112, and both the outer shell 113 and the inner shell 114 include the handle portion 111 and the actuating portion 112.

[0022] Among them, the housing 11 may be a long cylindrical housing 11, and with a long cylindrical housing 11, the air blowing passage 12 and the heat dissipation passage 13 are relatively straight, and under a certain power, a large air volume and wind force can be achieved, and the heat dissipation of the heat dissipation passage 13 can also be improved.

[0023] In some embodiments, the operating part 112 may include a first operating part 1121 and a second operating part 1122 arranged opposite each other, and the first operating part 1121 and the second operating part 1122 define and form a wind-blowing space 1123, and the wind-blowing port 122 is connected to the wind-blowing passage 12 and the wind-blowing space 1123. The air blowing passage 12 is located within the inner shell 114 and has an air inlet 121 and an air outlet 122. The air inlet 121 is located in the handle 111 and the air outlet 122 is located in the operating part 112. The heat dissipation passage 13 is located between the outer shell 113 and the inner shell 114 and has a heat dissipation inlet 131 and a heat dissipation outlet 132. The heat dissipation inlet 131 is located in the handle 111 and communicates with the air blowing passage 12, and the heat dissipation outlet 132 is located in the operating part 112. The driving member 14 and the heating member 15 are both mounted within the inner shell 114. The driving member 14 is connected to the heating member 15 and both the driving member 14 and the heating member 15 are located in the handle 111. The dashed line with an arrow in Figure 3 indicates the direction of airflow.

[0024] In this way, the hair styling device 100 heats with the heating element 15 and rotates the heating element 14 with the driving element 14, thereby forming a hot air current in the air-blowing passage 12, and the hot air current in the air-blowing passage 12 is blown into the air-blowing space 1123 through the air-blowing port 122, which helps to dry the hair. In addition, the first operating part 1121 and the second operating part 1122 are arranged opposite to each other to form the air-blowing space 1123, so that the air-blowing space 1123 becomes semi-open, which helps to concentrate the heat and speed of the air current, and the hot air current in the air-blowing space 1123 makes it easier to soften the hair. The high-speed air current enters the air-blowing space 1123, creating a wind pressure difference on different sides of the air-blowing space 1123, which further creates a tensile force, which also helps to straighten the softened hair, thereby meeting the usage needs of users in various situations. The air inside the inner shell 114 absorbs the heat generated by the operation of the heating element 15, and as a result, heat accumulates in the inner shell 114, causing it to heat up. However, the heat dissipation passage 13 allows the air to circulate, and can remove the heat from the inner shell 114, which helps to lower the temperature of the inner shell 114 and also helps to prevent the temperature of the outer shell 113 from becoming too high due to the heat from the inner shell 114 being conducted to the outer shell 113, thereby improving the user's experience.

[0025] The driving member 14 may be a driving structure such as a blower, an electric motor, a motor, or a driving plate, and the heating member 15 may be a heating structure such as a heating wire or a heat generating sheet, which can be specifically set according to actual conditions. The first operating portion 1121 and the second operating portion 1122 may have the same structure, or the first operating portion 1121 and the second operating portion 1122 may have different structures, or the first operating portion 1121 and the second operating portion 1122 may be arranged symmetrically, or the first operating portion 1121 and the second operating portion 1122 may be arranged asymmetrically, which can be specifically set according to actual conditions. The first operating portion 1121 and the second operating portion 1122 may be arranged separately and connected to the handle portion 111, so that the end of the operating portion 112 far from the handle portion 111 is generally U-shaped.

[0026] In use, a user can place their hair in the air-blowing space 1123, and when the driving member 14 and the heating member 15 are controlled and activated by the circuit board of the hair styling device 100, air enters the air-blowing passage 12 from the air inlet 121, is heated by the heating member 15, and then blows into the air-blowing space 1123 from the air-blowing port 122 to further dry the user's hair, or the hair styling device 100 creates an air pressure difference with the high-temperature, high-velocity airflow to further create tensile force and straighten the softened hair. In this way, the hair is located in the air-blowing space 1123, reducing the possibility of it becoming messy or tangled, and the airflow is blown from the air-blowing port 122 into the air-blowing space 1123 to directly act on the hair, reducing the airflow speed and heat loss.

[0027] The end of the airflow space 1123 may have an opening that widens outward, making it easier for the user to place hair through the opening into the airflow space 1123. The airflow passage 12 at the airflow outlet 122 may be a curved passage, and the airflow flows through the airflow passage 12 and the airflow outlet 122 in sequence before entering the airflow space 1123. Since the airflow is blown into the air-blowing space 1123 through the curved air-blowing passage 12, the air blown out from the curved air-blowing passage 12 enters the air-blowing space 1123 at a small angle compared to direct blowing into the air-blowing space 1123, and the high-speed airflow better creates a wind pressure difference on different sides of the air-blowing space 1123, which further generates tensile force and makes it easier to ensure the hair straightening function of the hair styling device 100. Furthermore, since the air blown out from the curved air-blowing passage 12 is blown onto the hair at a small angle, it also helps to reduce the occurrence of hair flying off when blown onto the hair. Furthermore, water droplets and moisture on the hair are also blown away from the hair, improving the efficiency of hair drying.

[0028] 2 to 4, in some embodiments, the first operating part 1121 and the second operating part 1122 each have an air blowing port 122. In this way, the airflow in the air blowing passage 12 can be blown out from the air blowing ports 122 of the first operating part 1121 and the second operating part 1122, respectively, which helps to increase the amount of blown air and improve the air blowing efficiency of the hair styling device 100.

[0029] Among them, the air blowing port 122 may be elongated, which helps to increase the air blowing area of ​​the air blowing port 122, thereby increasing the amount of air blown out of the hair styling device 100 and also helping to improve the air blowing efficiency of the hair styling device 100.

[0030] In some embodiments, both the first operating part 1121 and the second operating part 1122 have the heat dissipation outlet 132. In this way, the airflow in the heat dissipation passage 13 can be blown out from the heat dissipation outlet 132 of the first operating part 1121 and the second operating part 1122, which helps to increase the amount of air that is blown out and improves the heat dissipation efficiency of the hair styling device 100.

[0031] Wherein, the heat dissipation outlet 132 may be elongated, which helps to increase the air blowing area of ​​the heat dissipation outlet 132, thereby increasing the airflow volume of the hair styling device 100 and improving the air blowing efficiency of the hair styling device 100. In other embodiments, the heat dissipation outlet 132 may be in other shapes such as a circular hole or a triangular hole, which can be specifically set according to actual circumstances.

[0032] 2 and 5, in some embodiments, the heat dissipation inlet 131 is located in the inner shell 114 and the heat dissipation outlet 132 is located in the outer shell 113.

[0033] This contributes to a rational layout of the positions of the heat dissipation inlet 131 and the heat dissipation outlet 132, so that airflow can enter the heat dissipation passage 13 from the inner shell 114 and be discharged from the heat dissipation outlet 132 in the outer shell 113, thereby improving the heat dissipation of the inner shell 114.

[0034] In some embodiments, the heat dissipation outlet 132 is located on the outer shell 113 outside the airflow space 1123. This helps to reduce the communication between the heat dissipation outlet 132 and the airflow space 1123, helps to reduce the interference between the airflows of the airflow space 1123 and the heat dissipation outlet 132, and helps to ensure the normal operation of the airflow space 1123 and the heat dissipation passage 13.

[0035] For example, the heat dissipation air inlet 131 may be located on a side of the outer shell 113 that is closer to the wind-blowing space 1123, or the heat dissipation air inlet 131 may be located on a side of the outer shell 113 that is farther away from the wind-blowing space 1123, and this can be set specifically according to the actual situation. Below, an example will be described in which the heat dissipation air inlet 131 is located on a side of the outer shell 113 that is closer to the wind-blowing space 1123.

[0036] In some embodiments, the first operating part 1121 and the second operating part 1122 each have an opposing first side 1126 and a second side 1127, both of which are connected to the outside world, the air outlet 122 is located on the first side 1126, the heat dissipation outlet 132 is located close to the second side 1127 relative to the air outlet 122, and the driving member 14 drives the airflow in the air outlet passage 12 to flow through the air outlet 122 in a direction from the first side 1126 to the second side 1127.

[0037] In this way, the air outlet 122 and the heat dissipation outlet 132 are located on opposite sides of the operating part 112, which helps to better reduce the interference between the airflow at the air outlet 122 and the airflow at the heat dissipation outlet 132, and helps to better ensure the normal operation of the air outlet space 1123 and the heat dissipation passage 13.

[0038] In some embodiments, the actuating part 112 includes a top end 1124 and a middle end 1125, the top end 1124, the middle end 1125 and the handle part 111 being sequentially distributed along the length direction X of the housing 11, the middle end 1125 being located halfway along the length direction X of the actuating part 112, and the heat dissipation outlet 132 being located between the top end 1124 and the middle end 1125. The middle end 1125 may be located at the middle of the actuating part 112 in the length direction X of the housing 11.

[0039] In this way, it is useful for rationally arranging the position of the heat dissipation outlet 132, so that the heat dissipation outlet 132 can be positioned at a position farther from the handle portion 111 in the operating portion 112, which is useful for increasing the area of ​​the heat dissipation passage 13 in the operating portion 112, which is useful for better heat dissipation of the operating portion 112 through the heat dissipation passage 13, and which is useful for better reducing the situation in which the temperature of the outer shell 113 becomes too high due to the heat of the inner shell 114 at the position of the operating portion 112 being conducted to the outer shell 113.

[0040] 5 and 6, in some embodiments, the air intake 121 is located on the outer shell 113 and communicates with the air blowing passage 12, the heat dissipation air inlet 131 is located between the heating element 15 and the driving element 14, and the driving element 14 is located between the heat dissipation air inlet 131 and the air intake 121.

[0041] In this way, a portion of the air entering through the air intake 121 enters the heat dissipation air inlet 131 before the heating element 15, and is discharged from the heat dissipation air outlet 132 after passing through the heat dissipation passage 13, thereby reducing the temperature of the inner shell 114 and helping to reduce the occurrence of heat generated when the heating element 15 is operating entering the heat dissipation passage 13 from the heat dissipation air inlet 131, thereby helping to reduce the loss of heat generated by the heating element 15 and improving the efficiency of heating the air in the air blowing passage 12 by the heating element 15.

[0042] Furthermore, since the driving member 14 is located between the heat dissipation air inlet 131 and the air inlet 121, this helps to reduce the temperature of the driving member 14 and helps to reduce the situation where the temperature of the driving member 14 becomes too high. Furthermore, part of the air that enters through the air inlet 121 enters the air blowing passage 12 and can be discharged from the air blowing outlet 122 after passing through the driving member 14 and the heating member 15, thereby realizing the output of hot air by the hair styling device 100.

[0043] Referring to Figure 7, in some embodiments, the inner shell 114 is provided with a first flow guide section 1141 and a second flow guide section 1142, and the first flow guide section 1141 and the second flow guide section 1142 are opposed to each other so as to form a heat dissipation air inlet 131, and the first flow guide section 1141 is provided at an angle from the handle section 111 towards the actuating section 112 to the outside of the air blowing passage 12, and the second flow guide section 1142 is provided at an angle from the actuating section 112 towards the handle section 111 to the inside of the air blowing passage 12.

[0044] In this way, the first flow guide section 1141 and the second flow guide section 1142 restrict the running direction of the heat dissipation inlet 131, which helps the airflow to enter the heat dissipation passage 13 along a predetermined direction, which helps optimize the flow path of the airflow, and also helps to concentrate the airflow more and prevent it from dispersing, which helps to improve the heat dissipation effect of the inner shell 114 due to the airflow in the heat dissipation passage 13, which helps to reduce the resistance to the airflow by the housing 11 and other devices, and further helps to reduce collision friction between the airflow and the housing 11 and other devices, which helps to reduce noise.

[0045] 5 and 8, in some embodiments, the housing 11 may include an air guide wall 115, which is located within the heat dissipation passage 13 and between the heat dissipation inlet 131 and the heat dissipation outlet 132, and which is adapted to guide the airflow from the heat dissipation inlet 131 to the heat dissipation outlet 132.

[0046] In this way, the air guide wall 115 restricts the running direction of the heat dissipation passage 13, which helps the airflow to flow in a predetermined direction, optimizes the flow path of the airflow, and also helps to concentrate the airflow more and reduce the loss of the airflow as it enters the heat dissipation passage 13, thereby improving the heat dissipation effect of the inner shell 114 due to the airflow in the heat dissipation passage 13, and further helps to reduce collision friction between the airflow and the housing 11 and other devices, thereby helping to reduce noise.

[0047] For example, the air guide wall 115 may be partially inclined, for example, the heat dissipation air inlet 131 and the heat dissipation air outlet 132 are not positioned in a straight line, and a portion of the wall surface of the air guide wall 115 is a straight wall surface extending along the longitudinal direction X of the housing 11, and another portion of the wall surface of the air guide wall 115 is an inclined wall surface inclined from the heat dissipation air inlet 131 toward the heat dissipation air outlet 132, and the straight wall surface is connected to the inclined wall surface and is positioned close to the heat dissipation air inlet 131. As another example, the air guide wall 115 may be inclined, for example, the heat dissipation air inlet 131 and the heat dissipation air outlet 132 are not positioned in a straight line, and the air guide wall 115 may be inclined from the heat dissipation air inlet 131 toward the heat dissipation air outlet 132. As yet another example, the air guide wall 115 may be an arc-shaped wall surface, which can be specifically set according to actual conditions.

[0048] In some embodiments, the wind guide wall 115 includes a first sub-wall 1151 and a second sub-wall 1152, the housing 11 further includes a wind shielding wall 116, the wind shielding wall 116 is connected to the first sub-wall 1151 and the second sub-wall 1152, and the heat dissipation air inlet 131 is located within a space surrounded by the wind shielding wall 116, the first sub-wall 1151, and the second sub-wall 1152.

[0049] In this way, by surrounding the heat dissipation air inlet 131 with the windshield wall 116, the first sub-wall 1151, and the second sub-wall 1152, the airflow entering from the heat dissipation air inlet 131 can flow along the first sub-wall 1151 and the second sub-wall 1152 to the heat dissipation air outlet 132, reducing the loss of the airflow as it enters the heat dissipation passage 13, and the windshield wall 116 helps to block the flow of airflow in a direction away from the heat dissipation air outlet 132, which also helps to reduce the loss of the airflow, helps to ensure that there is sufficient airflow in the heat dissipation passage 13, and helps to ensure the heat dissipation effect on the inner shell 114.

[0050] 2 and 9, in some embodiments, a plurality of flow guide plates 1221 are provided in the air outlet 122, and the plurality of flow guide plates 1221 are spaced apart and distributed along the longitudinal direction X of the housing 11. In this way, the plurality of flow guide plates 1221 divide the air outlet 122 into a plurality of independent sub-air outlets, improving the uniformity with which the airflow in the air outlet passage 12 is blown into the air outlet space 1123.

[0051] For example, the flow guide plate 1221 may be an arc-shaped plate to better fit the inner wall of the inner shell 114. The distance between any two adjacent flow guide plates 1221 may be set to 2 mm or more and 8 mm or less, and can be set according to specific actual conditions.

[0052] Referring again to FIG. 5, in some embodiments, the housing 11 may include a plurality of support members 16, which are spaced apart within the heat dissipation passage 13, with one side of each of the support members 16 abutting the inner shell 114 and the other side of each of the support members 16 abutting the outer shell 113.

[0053] In this way, the multiple support members 16 can respectively support the inner shell 114 and the outer shell 113, which helps to reduce the situation where the inner shell 114 and the outer shell 113 come close to each other and are stuck together, helps to ensure that there is sufficient space between the inner shell 114 and the outer shell 113, and helps to ensure that there is sufficient space in the heat dissipation passage 13, so that the airflow can better flow through the heat dissipation passage 13 and lower the temperature of the inner shell 114.

[0054] In some embodiments, the gap between the inner shell 114 and the outer shell 113 is 0.2 mm to 2.0 mm. This helps to ensure that there is a sufficient gap between the inner shell 114 and the outer shell 113, helps to ensure that there is sufficient space in the heat dissipation path 13, helps to reduce the situation where there is insufficient space in the heat dissipation path 13 due to an insufficient gap between the inner shell 114 and the outer shell 113, making it impossible to dissipate heat, and helps to reduce the situation where the dimensional volume of the hair styling device 100 becomes too large due to an excessively large gap between the inner shell 114 and the outer shell 113.

[0055] For example, the gap between the inner shell 114 and the outer shell 113 may be 0.2 mm, 0.4 mm, 0.6 mm, 0.9 mm, 1.2 mm, 1.5 mm, 1.7 mm, 1.9 mm, 2.0 mm, or any value between two adjacent values ​​above, and can be specifically set according to actual conditions.

[0056] To summarize the above, in the hair styling device 100 according to an embodiment of the present invention, the housing 11 of the hair styling device 100 is provided with a handle portion 111 and an actuation portion 112 that are connected to each other, and the housing 11 includes an outer shell 113 and an inner shell 114, and the outer shell 113 is surrounded by the outer periphery of the inner shell 114. The air blowing passage 12 is located within the inner shell 114, and has an air inlet 121 and an air outlet 122, the air inlet 121 being located in the handle portion 111 and the air outlet 122 being located in the operating portion 112, the heat dissipation passage 13 being located between the outer shell 113 and the inner shell 114, and has a heat dissipation inlet 131 and a heat dissipation outlet 132, the heat dissipation inlet 131 being located in the handle portion 111 and communicating with the air blowing passage 12, the heat dissipation outlet 132 being located in the operating portion 112. The driving member 14 and the heating member 15 are both located within the heat dissipation passage 13, the driving member 14 being connected to the heating member 15, and the driving member 14 and the heating member 15 being located in the handle portion 111. In this way, the hair styling device 100 heats with the heating element 15 and rotates the heating element 14 with the driving element 15, thereby forming a hot air current in the air-blowing passage 12, and the hot air current in the air-blowing passage 12 is blown into the air-blowing space 1123 through the air-blowing port 122, which helps to dry the hair. In addition, the first operating part 1121 and the second operating part 1122 are arranged opposite to each other to form the air-blowing space 1123, so that the air-blowing space 1123 becomes semi-open, which helps to concentrate the heat and speed of the air current, and the hot air current in the air-blowing space 1123 makes it easier to soften the hair. The high-speed air current enters the air-blowing space 1123, creating a wind pressure difference on different sides of the air-blowing space 1123, which further creates tensile force and helps to straighten the softened hair, thereby meeting the usage needs of users in various situations. The air inside the inner shell 114 absorbs the heat generated by the operation of the heating element 15, and as a result, heat accumulates in the inner shell 114, causing it to heat up. However, the heat dissipation passage 13 allows the air to circulate, and can remove the heat from the inner shell 114, which helps to lower the temperature of the inner shell 114 and also helps to prevent the temperature of the outer shell 113 from becoming too high due to the heat from the inner shell 114 being conducted to the outer shell 113, thereby improving the user's experience.
