Description

Technical Field

[0001] The present invention relates to the technical field of hair styling equipment, and in particular to an air guide structure and a hair styling equipment comprising the same. Background Art

[0002] A hair dryer comb is a popular hair styling tool in recent years. In the prior art, a hair dryer comb generally has an air guide structure, and the air guide structure includes a shell, a plurality of air outlet holes arranged on the circumference of the shell and arranged in sequence along the axial direction of the shell, and an air guide member arranged in the shell and suitable for guiding airflow to the air outlet holes.

[0003] However, due to the unreasonable setting of the air guide, in actual use, the air outlet temperatures of the various air outlet holes arranged along the axial direction of the shell of the air guide structure will vary greatly. For example, in some hair dryers, the air supply system is located at the rear end of the air guide structure, and the airflow needs to reach the front end of the air guide structure along the axial direction of the shell before flowing to the air outlet holes on the peripheral side of the air guide structure. As a result, the air outlet temperature at the rear end along the axial direction of the shell is the highest, the air outlet temperature at the front end along the axial direction of the shell is the second highest, and the air outlet temperature at the middle air outlet hole along the axial direction of the shell is the lowest, which results in uneven air outlet temperatures of the various air outlet holes arranged along the axial direction of the shell, thereby affecting the blowing and styling effects. Summary of the invention

[0004] An embodiment of the present invention provides an air guide structure and a hair styling device comprising the same. By sequentially arranging a plurality of air guide members, the airflow from the air inlet can be sequentially guided to each air outlet along the air inlet direction, thereby shortening the path and time of the airflow guiding the front air outlets (the second to fourth air outlets), especially the path and time of the airflow guiding the air outlets (the second and third air outlets) located in the middle of the air outlet path, thereby reducing or eliminating the difference in air outlet temperature at each air outlet, so that the distribution of the air outlet temperature of each air outlet is more uniform.

[0036] An embodiment of the present invention provides a wind guide structure.

[0038] Reference Figures 1 to 6 The air guide structure 10 includes a shell 11, an air flow cavity 12, an air inlet 13, M air outlet holes 141, 142, 143, 144, and N air guide members 151, 161, 152, 153, 162, 154, 163.

[0039] Specifically, the housing 11 is suitable for forming an airflow cavity 12 therein. An air inlet 13 is provided at the housing 11 and communicated with the airflow cavity 12 to allow airflow outside the housing 11 to enter the airflow cavity 12. M air outlet holes 141, 142, 143, 144 are provided at the housing 11 and communicated with the airflow cavity 12 to allow airflow to leave the airflow cavity 12. N air guides 151, 161, 152, 153, 162, 154, 163 are provided in the airflow cavity 12 to guide the airflow in the airflow cavity 12 to the M air outlet holes 141, 142, 143, 144.

[0040] In a specific implementation, M and N are respectively positive integers greater than or equal to 3. Furthermore, the M air outlets 141, 142, 143, 144 are sequentially arranged along the air inlet direction, and the N air guides 151, 161, 152, 153, 162, 154, 163 are also sequentially arranged along the air inlet direction.

[0041] The inner sides of the 1st to (N-1)th air guide members 151, 161, 152, 153, 162 among the N air guide members 151, 161, 152, 153, 162, 154, 163 are suitable for allowing airflow to pass through along the air inlet direction, and the outer sides thereof are suitable for stripping the airflow in sequence to guide the airflow to the M air outlet holes 141, 142, 143, 144 in sequence along the air inlet direction.

[0042] The Nth air guide member 154, 163 among the N air guide members 151, 161, 152, 153, 162, 154, 163 is suitable for reflecting the airflow to guide the airflow to at least one air outlet hole 141, 142, 143, 144 among the M air outlet holes 141, 142, 143, 144.

[0043] In the embodiment of the present invention, the plane where the orthographic projection of each of the M air outlet holes 141 , 142 , 143 , 144 lies has a certain angle with the plane where the orthographic projection of the air inlet 13 lies.

[0044] In some embodiments, the angle between the plane where the orthographic projection of each of the M air outlet holes 141 , 142 , 143 , 144 is located and the plane where the orthographic projection of the air inlet 13 is located includes 90 degrees.

[0045] In the embodiment of the present invention, the air inlet direction may be the direction in which the airflow outside the housing 11 enters the airflow cavity 12 along the air inlet 13 .

[0046] In some embodiments, the air inlet direction may be perpendicular to the plane where the orthographic projection of the air inlet 13 is located. In this case, the air outlet direction may be perpendicular to the air inlet direction.

[0047] It is understandable that the air inlet direction can be controlled or determined by an air supply system outside the air guide structure 10 .

[0048] In some embodiments, the airflow cavity 12 is adapted to extend along the air inlet direction. The air inlet 13 is disposed at one end of the airflow cavity 12. M air outlet holes 141, 142, 143, 144 are sequentially disposed around the airflow cavity 12 along the air inlet direction. The side of the airflow cavity 12 may be defined by the side wall of the housing 11.

[0049] In a specific implementation, the housing 11 may include a hollow cylindrical structure extending along the air inlet direction. The hollow portion of the cylindrical structure may extend along the air inlet direction and is suitable for forming an airflow cavity 12, and one end of the cylindrical structure is open to form an air inlet 13 connected to the airflow cavity 12. M air outlet holes 141, 142, 143, 144 are provided on the side wall of the cylindrical structure and penetrate the side wall.

[0050] In the embodiment of the present invention, the extension of the airflow cavity 12 along the air inlet direction may include a situation where the axial direction of the airflow cavity 12 is parallel to the air inlet direction, or a situation where the axial direction of the airflow cavity 12 forms an acute angle with the air inlet direction.

[0051] In some embodiments, at least two groups of the M air outlet holes 141, 142, 143, 144 are provided. Moreover, each group of the at least two groups of the M air outlet holes 141, 142, 143, 144 is respectively distributed along the circumference of the side wall of the housing 11, and the M air outlet holes 141, 142, 143, 144 in each group are sequentially arranged along the air inlet direction.

[0052] In some embodiments, each group of the at least two groups of M air outlet holes 141 , 142 , 143 , 144 is evenly distributed along the circumference of the housing 11 .

[0053] In some embodiments, each group of M air outlet holes 141, 142, 143, 144 can be sequentially referred to as the first air outlet hole 141, the second air outlet hole 142, ..., the Mth air outlet hole 144 along the air inlet direction.

[0054] In some embodiments, the N air guides 151, 161, 152, 153, 162, 154, 163 may be respectively referred to as the first air guide 151, 161, the second air guide 152, 153, 162, ..., the Nth air guide 154, 163 along the air inlet direction.

[0055] In a specific implementation, the inner sides of the 1st to (N-1)th air guide members 151, 161, 152, 153, 162 among the N air guide members 151, 161, 152, 153, 162, 154, 163 are suitable for allowing airflow to pass through along the air inlet direction, and the outer sides thereof are suitable for stripping off the airflow in sequence to guide the airflow to the M air outlet holes 141, 142, 143, 144 in sequence along the air inlet direction.

[0056] In some embodiments, the 1st to (N-1)th air guides 151, 161, 152, 153, 162 all extend along the air inlet direction from the inside of the air flow cavity 12 toward the peripheral side of the air flow cavity 12, that is, toward the inner side of the side wall of the shell 11.

[0057] In some embodiments, at least one of the 1st to (N-1)th air guides 151 , 161 , 152 , 153 , 162 extends from the inside of the air flow cavity 12 along the air inlet direction and is connected to the side wall of the shell 11 .

[0058] In some embodiments, the connection position between the air guide members extending from the 1st to the (N-1)th air guide members 151, 161, 152, 153, 162 and connected to the side wall of the shell 11 and the side wall can be located between two adjacent air outlets.

[0059] In some embodiments, the first air guide 151, 161 extends from the inside of the air flow cavity 12 along the air inlet direction and is connected to the side wall, and each air guide 152, 153, 162 from the second to the (N-1)th air guide 152, 153, 162 is connected to the previous air guide in sequence.

[0060] It is understandable that the direction referred to by "upper" in "previous air guide member" is different from the air inlet direction. For example, along the air inlet direction, the first air guide members 151, 161, the second air guide members 152, 162, and the third air guide members 153, 163 are arranged in sequence, and the previous air guide member of the second air guide members 152, 162 is the first air guide member 151, 161, not the third air guide member 153, 163.

[0061] In the embodiments of the present invention, the "front" and "rear" mentioned are all based on the air inlet direction, that is, "front" refers to the front along the air inlet direction, and "rear" refers to the rear along the air inlet direction.

[0062] In some embodiments, a connector may be provided between two adjacent air guides to connect the two adjacent air guides. For example, a strip-shaped connector may be used, and the two ends of the connector are respectively connected to the two adjacent air guides to achieve connection of the two adjacent air guides.

[0063] In other embodiments, any connection method known in the prior art may be used to connect two adjacent air guide members.

[0064] In some embodiments, the 1st to (N-1)th air guides 151, 161, 152, 153, 162 have a curved surface that is recessed away from the side wall on one side of each side wall facing the shell 11, so as to guide the stripped airflow to the corresponding air outlet.

[0065] In some embodiments, the first to (N-1)th air guides 151, 161, 152, 153, 162 of the N air guides 151, 161, 152, 153, 162, 154, 163 may include a trumpet-shaped structure that is through from front to back, and the inner diameter of the trumpet-shaped structure may gradually increase along the air inlet direction. In this way, the inner side thereof may be adapted to allow the airflow to flow forward along the air inlet direction.

[0066] In some embodiments, the trumpet-shaped structures of the 1st to (N-1st)th air guides 151 , 161 , 152 , 153 , 162 may have the same shape and size.

[0067] In other embodiments, the size and shape of the trumpet-shaped structures of the 1st to (N-1)th air guides 151, 161, 152, 153, 162 can be different. In this case, the rear end outer diameter of the next air guide 152, 162 along the air inlet direction is less than the front end inner diameter of the previous air guide 151, 161, so that the previous air guide 151, 161 strips the airflow and guides the corresponding air outlet.

[0068] When the airflow outside the shell 11 enters the airflow cavity 12 through the air inlet 13, the inner sides (inner sides of the trumpet-shaped structure) of the 1st to (N-1)th air guides 151, 161, 152, 153, 162 can allow the airflow to pass through along the air inlet direction, while the outer sides (outer sides of the trumpet-shaped structure) thereof are suitable for stripping off the airflow in sequence to guide the airflow in sequence along the air inlet direction to the M air outlet holes 141, 142, 143, 144 located on the side wall of the shell 11.

[0069] It is understandable that the inner side of the air guide member refers to the side of the air guide member close to the central axis of the airflow cavity 12, while the outer side of the air guide member refers to the side of the air guide member close to the air outlet. For example, for an air guide member having a trumpet-shaped structure that is through-through, the inner through-through portion is suitable for allowing the airflow to pass along the air inlet direction, while the outer side is suitable for stripping the airflow and directing the stripped airflow along the outer side wall of the air guide member to the corresponding air outlet.

[0070] In some embodiments, the number of air guides may be the same as the number of each group of air outlets, wherein the positions of the 1st to (N-1st) air guides 151, 161, 152, 153, 162 in the airflow cavity 12 may correspond to each of the 1st to (M-1st) air outlets 141, 142, 143. For example, the front end of the air guide may be located at the side of the corresponding air outlet, or aligned with the front end of the corresponding air outlet; and the rear end of the air guide may be located at the side of the air outlet, or aligned with the rear end of the corresponding air outlet.

[0071] In this way, the airflow can be stripped in sequence through the 1st to (N-1)th air guides 151, 161, 152, 153, 162, so that the stripped airflow is smoothly guided to the 1st to (M-1)th air outlets 141, 142, 143 in sequence.

[0072] It can be understood that when the air guide is not extended and connected to the side wall of the shell 11, there is a gap between it and the side wall of the shell 11, and the gap can also continue to guide the airflow to the front.

[0073] In a specific implementation, the Nth air guide 154, 163 among the N air guides 151, 161, 152, 153, 162, 154, 163 is suitable for reflecting airflow and directing the reflected airflow to at least one air outlet hole 141, 142, 143, 144 among the M air outlet holes 141, 142, 143, 144.

[0074] In a specific implementation, the airflow cavity 12 is closed at the other end thereof opposite to the air inlet 13 .

[0075] In some embodiments, the Nth air guide 154, 163 is disposed at the other end of the air flow cavity 12 (the end away from the air inlet 13) and closes the air flow cavity 12 at this end.

[0076] In a specific implementation, the Nth air guide members 154 , 163 extend from the side wall of the housing 11 toward the interior of the airflow cavity 12 along a direction away from the incoming air.

[0077] In some embodiments, the Nth air guide 154, 163 includes a conical structure 1541, 1631. The top of the conical structure 1541, 1631 faces the (N-1)th air guide 153, 162, and the bottom of the conical structure 1541, 1631 faces the other end of the air flow cavity 12 to guide the air flow to at least one of the M air outlet holes 141, 142, 143, 144.

[0078] In some embodiments, the conical structure 1541, 1631 has a curved surface that is recessed away from the side wall on the side facing the shell 11, so as to reflect the airflow and guide the airflow to at least at least one of the M air outlet holes 141, 142, 143, 144.

[0079] Reference Figures 4 to 6 In some embodiments, the Nth air guide 163 further includes an extension portion 1632 connected to the conical structure 1631. The extension portion 1632 may extend from the outer side wall of the conical structure 1631 to the side wall of the housing 11 and include an arc surface that is concave along the air inlet direction. In this way, the airflow can be better reflected and the reflected airflow can be directed to at least one of the M air outlet holes 141, 142, 143, 144.

[0080] In some embodiments, the top of the conical structure 1631 may be located on the side of the Mth air outlet 144, and the bottom of the conical structure 1631 may extend to the outside of the front end of the Mth air outlet 144 to better reflect the airflow.

[0081] When the airflow travels to the closed end of the airflow cavity 12 , the airflow can be reflected by the Nth air guide 154 , 163 , and the reflected airflow can be directed to at least one of the M air outlet holes 141 , 142 , 143 , 144 .

[0082] Reference Figures 1 to 3 In some embodiments, M may be 4; N may be 4. In this case, the air guide structure 10 may include four air outlet holes, namely, a first air outlet hole 141, a second air outlet hole 142, a third air outlet hole 143, and a fourth air outlet hole 144, which are sequentially arranged along the air inlet direction, and four air guide members, namely, a first air guide member 151, a second air guide member 152, a third air guide member 153, and a fourth air guide member 154, which are sequentially arranged along the air inlet direction.

[0083] In a specific implementation, the first to third air guides 151, 152, 153 are suitable for stripping off the airflow in sequence and directing the airflow to the first to third air outlets 141, 142, 143, respectively; the fourth air guide 154 is suitable for reflecting the airflow and directing the airflow to at least at least one of the first to fourth air outlets 141, 142, 143, 144.

[0084] Specifically, the first air guide 151 is suitable for stripping the airflow and directing the airflow to the first air outlet 141. The second air guide 152 is suitable for stripping the airflow and directing the airflow to the second air outlet 142. The third air guide 153 is suitable for stripping the airflow and directing the airflow to the third air outlet 143. The fourth air guide 154 is suitable for reflecting the airflow and directing the reflected airflow to at least one of the first to fourth air outlets 141, 142, 143, 144.

[0085] In some embodiments, the first to fourth air guides 151 , 152 , 153 , 154 are all suitable for extending from the inside of the air flow cavity 12 toward the inner side of the side wall of the shell 11 along the air inlet direction, and are connected to the inner side of the side wall of the shell 11 .

[0086] In some embodiments, the connection position between the first air guide 151 and the inner side of the side wall of the housing 11 (corresponding to the front peripheral side of the first air guide 151) can be located at the front end of the first air outlet 141, or between the first air outlet 141 and the second air outlet 142. The connection position between the second air guide 152 and the inner side of the side wall of the housing 11 (corresponding to the front peripheral side of the second air guide 152) can be located at the front end of the second air outlet 142, or between the second air outlet 142 and the third air outlet 143. The connection position between the third air guide 153 and the inner side of the side wall of the housing 11 (corresponding to the front peripheral side of the third air guide 153) can be located at the front end of the third air outlet 143, or between the third air outlet 143 and the fourth air outlet 144. The connection position between the 4th air guide member 154 and the inner side of the side wall of the shell 11 (corresponding to the front end peripheral side of the 4th air guide member 154) can be located at the front end of the airflow cavity 12, and the front end of the 4th air guide member 154 can be aligned with the front end of the airflow cavity 12.

[0087] In some embodiments, the first to third air guide members 151 to 153 may each include a trumpet-shaped structure that passes through from front to back, and the inner diameter of the trumpet-shaped structure increases sequentially along the air inlet direction.

[0088] In some embodiments, the inner side of the first air guide 151, i.e., the front-to-back through portion of the first air guide 151, is suitable for allowing the airflow from the air inlet 13 to pass through in the air inlet direction; the outer side of the first air guide 151, i.e., the outer side wall of the first air guide 151, is suitable for stripping the airflow and directing the stripped airflow to the first air outlet 141. The inner side of the second air guide 152, i.e., the front-to-back through portion of the second air guide 152, is suitable for allowing the airflow from the air inlet 13 to pass through in the air inlet direction; the outer side of the second air guide 152, i.e., the outer side wall of the second air guide 152, is suitable for stripping the airflow and directing the stripped airflow to the second air outlet 142. The inner side of the third air guide member 153, that is, the front-to-back penetrating portion of the third air guide member 153, is suitable for allowing the airflow from the air inlet 13 to pass through along the air inlet direction; the outer side of the third air guide member 153, that is, the outer side wall of the third air guide member 153, is suitable for stripping the airflow and guiding the stripped airflow to the third air outlet 143.

[0089] In some embodiments, the fourth air guide 154 is disposed at the other end of the air flow cavity 12 (the end away from the air inlet 13 ), and closes the air flow cavity 12 at this end.

[0090] In a specific implementation, the fourth air guide 154 is suitable for extending from the side wall of the shell 11 toward the interior of the air flow cavity 12 along a direction away from the incoming air.

[0091] In some embodiments, the fourth air guide 154 is suitable for reflecting airflow and directing the reflected airflow to at least the fourth air outlet 144 among the first to fourth air outlets 141 , 142 , 143 , 144 .

[0092] In some embodiments, the 4th air guide 154 also has a curved surface that is recessed away from the side wall on the side facing the shell 11, so as to reflect the airflow and guide the reflected airflow to at least the 4th air outlet 144 among the 1st to 4th air outlets 141, 142, 143, 144.

[0093] When the front end of the third air guide 153 is located at the side of the third air outlet 143 , the fourth air guide 154 can also guide the reflected airflow to the third air outlet 143 .

[0094] When there are gaps between the first to third air guides 151 , 152 , 153 and the side walls of the shell 11 , respectively, the airflow reflected by the fourth air guide 154 can also flow to the first to third air outlets 141 , 142 , 143 through these gaps.

[0095] In some embodiments, the fourth air guide 154 includes a conical structure 1541. The top of the conical structure 1541 faces the third air guide 153, and the bottom of the conical structure 1541 faces the other end of the air flow cavity 12 to guide the air flow to at least one of the four air outlet holes 141, 142, 143, 144.

[0096] In a specific implementation, the axis of the conical structure 1541 may be parallel to the axis of the airflow cavity 12 .

[0097] In some embodiments, the conical structure 1541 has a curved surface that is recessed away from the side wall on the side of the side wall facing the shell 11 (i.e., the outer wall of the conical structure 1541) to facilitate reflecting the airflow and directing the reflected airflow to at least at least one of the first to fourth air outlets 141, 142, 143, 144.

[0098] In this way, when the airflow reaches the closed end of the airflow cavity 12 , the airflow can be reflected by the fourth air guide 154 to guide the airflow to at least one of the first to fourth air outlets 141 , 142 , 143 , 144 .

[0099] Reference Figures 4 to 6 In some embodiments, M may be 4, and N may be 3. In this case, the air guide structure 10 may include four air outlet holes, namely, a first air outlet hole 141, a second air outlet hole 142, a third air outlet hole 143, and a fourth air outlet hole 144, which are sequentially arranged along the air inlet direction, and three air guide members, namely, a first air guide member 161, a second air guide member 162, and a third air guide member 163, which are sequentially arranged along the air inlet direction.

[0100] In a specific implementation, the first air guide 161 is suitable for stripping off the airflow and directing the airflow to the first air outlet 141. The second air guide 162 is suitable for stripping off the airflow and directing the airflow to at least the second and third air outlets 142 and 143.

[0101] In some embodiments, the first air guide 161 is adapted to extend from the inside of the airflow cavity 12 toward the inner side of the side wall of the housing 11 along the air inlet direction, and is connected to the inner side of the side wall of the housing 11. Furthermore, the connection position between the first air guide 161 and the inner side of the side wall of the housing 11 (corresponding to the front peripheral side of the first air guide 161) can be located at the front end of the first air outlet 141, or between the first air outlet 141 and the second air outlet 142.

[0102] In some embodiments, the first air guide 161 may include a trumpet-shaped structure that passes through from front to back, and the inner diameter of the trumpet-shaped structure increases sequentially along the air inlet direction.

[0103] In a specific implementation, the inner side of the first air guide 161, i.e., the front-to-back through portion of the first air guide 161, is suitable for allowing the airflow from the air inlet 13 to pass through along the air inlet direction. The outer side of the first air guide 161, i.e., the outer side wall of the first air guide 161, is suitable for stripping the airflow and directing the stripped airflow to the first air outlet 141.

[0104] In some embodiments, the second air guide 162 may extend at least from the second air outlet 142 to the third air outlet 143 along the air inlet direction. For example, the second air guide 162 may extend from the rear end of the second air outlet 142 to the side of the third air outlet 143 along the air inlet direction. In this way, the airflow may be stripped by the second air guide 162 and directed to the second air outlet 142 and the third air outlet 143.

[0105] In some embodiments, the second air guide 162 is also adapted to extend from the inside of the airflow cavity 12 toward the inside of the side wall of the housing 11 along the air inlet direction, and is connected to the inside of the side wall of the housing 11. Furthermore, the connection position between the second air guide 162 and the inside of the side wall of the housing 11 (corresponding to the front peripheral side of the second air guide 162) can be located at the side of the third air outlet 143, or between the third air outlet 143 and the fourth air outlet 144.

[0106] In the case where the second air guide member 162 is not extended and connected to the side wall of the shell 11 or the second air guide member 162 and the side wall of the shell 11 are not completely seamlessly connected (i.e., the second air guide member 162 and the side wall of the shell 11 are only partially connected along the circumferential direction), there may be a gap between it and the side wall of the shell 11, and the gap can also continue to guide the airflow to the fourth air outlet 144 in the front.

[0107] In some embodiments, the third air guide 163 is disposed at the other end of the air flow cavity 12 (the end away from the air inlet 13 ), and closes the air flow cavity 12 at this end.

[0108] In a specific implementation, the third air guide 163 is suitable for reflecting airflow and directing the reflected airflow to at least one of the first to fourth air outlet holes 141 , 142 , 143 , 144 .

[0109] In a specific implementation, the third air guide 163 extends from the side wall of the housing 11 toward the interior of the airflow cavity 12 along a direction away from the incoming air.

[0110] In some embodiments, the third air guide 163 includes a conical structure 1631. The top of the conical structure 1631 faces the second air guide 162, and the bottom of the conical structure 1631 faces the other end of the air flow cavity 12, so as to guide the air flow to at least the fourth air outlet 144 among the first to fourth air outlets 141, 142, 143, 144.

[0111] When the front end of the second air guide 162 is located at the side of the third air outlet 143 , the third air guide 163 can also guide the reflected airflow to the second air outlet 142 .

[0112] When there are gaps between the first air guide 161 and the second air guide 162 and the side walls of the housing 11 , respectively, the airflow reflected by the third air guide 163 can also flow toward the first to third air outlets 141 , 142 , 143 through these gaps.

[0113] In some embodiments, the conical structure 1631 has a curved surface that is recessed away from the side wall on the side of the side wall facing the shell 11, so as to facilitate reflecting the airflow and directing the reflected airflow to at least at least one of the first to fourth air outlets 141, 142, 143, 144.

[0114] In some embodiments, the third air guide 163 further includes an extension portion 1632 connected to the conical structure 1631. The extension portion 1632 may extend from the outer side wall of the conical structure 1631 to the side wall of the housing 11 and include an arc surface that is concave along the air inlet direction. In this way, the airflow can be better reflected and directed to at least one of the first to fourth air outlets 141, 142, 143, 144.

[0115] In some embodiments, the top of the conical structure 1631 may be located on the side of the fourth air outlet 144, and the bottom of the conical structure 1631 may extend to the outside of the front end of the fourth air outlet 144 to better reflect the airflow.

[0116] In this way, when the airflow travels to the closed end of the airflow cavity 12, the airflow can be reflected by the third air guide 163 and the reflected airflow can be directed to at least one of the first to fourth air outlets 141, 142, 143, 144.

[0117] In the embodiment of the present invention, the above-mentioned technical scheme is adopted, so that the airflow from the air inlet 13 can be guided to each air outlet in sequence along the air inlet direction, thereby shortening the path and time of the airflow guiding to the front air outlets (the 2nd to the 4th air outlets), especially the path and time of the airflow guiding to the middle air outlets (the 2nd and the 3rd air outlets), thereby reducing or eliminating the difference in the air outlet temperature at each air outlet, so that the distribution of the air outlet temperature of each air outlet is more uniform.

[0118] The embodiment of the present invention also provides a hair styling device.

[0119] Figure 7 Schematic diagram of a hair styling device according to an embodiment of the present invention.

The air supply system 20 is connected to the air inlet 13 of the air guide structure 10 to provide air flow to the air flow cavity 12 thereof.

[0121] In some embodiments, the air supply system 20 may include a handle 21 and an aerodynamic part 22 connected to each other. The handle 21 is a hollow structure, one end of which is connected to the air inlet 13 of the air guide structure 10, and the other end is connected to the aerodynamic part 22. The aerodynamic part 22 is suitable for providing a heated airflow to the air guide structure 10 through the handle 21.

[0122] In a specific implementation, the handle 21 and the pneumatic part 22 can be implemented by any known existing technical means in the art, which is not limited here.

[0123] In some embodiments, the hair styling device 1 further includes bristles disposed on the outside of the housing 11 of the air guide structure 10 .

[0124] In a specific implementation, the bristles may be distributed along the M air outlet holes 141 , 142 , 143 , and 144 .

[0125] In some embodiments, the M air outlet holes 141 , 142 , 143 , 144 and the bristles can be arranged in at least two groups. Moreover, the groups of air outlet holes and the groups of bristles are arranged at intervals from each other along the circumference of the housing 11 .
