[0033] Next, refer to Figures 1-4 , and describe the air outlet component 10 according to the embodiment of the present utility model.

[0034] As Figure 1 and Figure 4 shown, the air outlet component 10 of the embodiment of the present utility model includes a skeleton 11 and blades 12. A first air duct 101 is provided inside the skeleton 11, and a through hole 11a communicating with the first air duct 101 is provided on the side wall of the skeleton 11; there are a plurality of blades 12, and they are sequentially arranged on the skeleton 11 along the circumferential direction of the skeleton 11. The projections of any two adjacent blades 12 on the outer peripheral side surface of the skeleton 11 do not intersect. Each blade 12 corresponds to at least one through hole 11a, and a second air duct 102 is defined between each blade 12 and the skeleton 11. The second air duct 102 communicates the through hole 11a with the outside of the air outlet component 10, and the air outlet direction of the second air duct 102 is inclined with respect to the outer peripheral side surface of the skeleton 11.

[0035] The first air duct 101 may refer to a channel formed inside the skeleton 11 for the flow of air.

[0036] It can be understood that since a plurality of blades 12 are sequentially arranged along the circumferential direction of the framework 11, and each blade 12 corresponds to at least one through hole 11a, therefore, the through holes 11a are also arranged in plurality along at least the circumferential side of the framework 11 (see Figure 1 ), whereby the air flow in the first air duct 101 can evenly flow to the position where each blade 12 is located.

[0037] "A second air duct 102 is defined between each blade 12 and the framework 11" can be understood as that the gap between the surface of the blade 12 close to the framework 11 and the outer surface of the framework 11 forms the second air duct 102.

[0038] The outer peripheral side surface of the framework 11 may refer to the side surface formed by the framework 11 around the extending direction of the first air duct 101.

[0039] Since each blade 12 corresponds to at least one through hole 11a, and the through hole 11a communicates with the first air duct 101 and the second air duct 102 formed between the blade 12 and the framework 11, the air flow in the first air duct 101 can flow to the second air duct 102 through the through hole 11a. Moreover, since the air outlet direction of the second air duct 102 is inclined with respect to the outer peripheral side surface of the framework 11, after the air flow blows out from the second air duct 102, it can form a certain included angle with respect to the outer peripheral side surface of the air outlet component 10. Since there are a plurality of blades 12, a plurality of second air ducts 102 are also formed, so that the air can be blown along the clockwise or counterclockwise direction on the outer peripheral side of the air outlet component 10.

[0040] According to the air outlet component 10 of the embodiment of the present invention, the air outlet component 10 is a split structure. Thus, after the framework 11 and the blades 12 are respectively manufactured, they can be spliced to form the air outlet component 10, thereby reducing the mold opening difficulty or the manufacturing process difficulty and reducing the manufacturing cost. Moreover, since a plurality of blades 12 are sequentially arranged along the circumferential direction of the framework 11 on the framework 11, and the projections of any two adjacent blades 12 on the outer peripheral side surface of the framework 11 do not intersect, therefore, the size of each blade 12 can be made relatively small, which can save materials and further reduce the manufacturing cost. During the later use process, when one of the framework 11 and the blades 12 is damaged, only the damaged component needs to be replaced, thereby reducing the use cost.

[0041] Optionally, as Figure 1 shown, a plurality of blades 12 are sequentially connected end to end and surround the framework 11. Optionally, a plurality of blades 12 can also be arranged at intervals along the circumferential direction of the framework 11.

[0042] Optionally, as Figure 2As shown, the blade 12 can be a strip-shaped blade, that is, the blade 12 can extend along the axial direction of the framework 11. At the position of the framework 11 corresponding to each blade 12, a plurality of through holes 11a can be provided, and the plurality of through holes 11a are arranged at intervals along the axial direction of the framework 11. The blade 12 can also be a short blade. For example, in the axial direction of the framework 11, a plurality of blades 12 can also be provided. At the position of the framework 11 corresponding to each blade 12, a plurality of through holes 11a can be provided, and the plurality of through holes 11a are arranged at intervals along the axial direction of the framework 11.

[0043] In some embodiments of the present invention, as Figure 2 shown, a plurality of groups of through holes 11a are provided along the circumferential direction of the framework 11. Each group of through holes 11a has a plurality along the axial direction of the framework 11. The blade 12 is provided with a hook 121, and the hook 121 cooperates with at least one of each group of through holes 11a and can pass through the through hole 11a and abut against the inner wall of the framework 12.

[0044] It can be understood that the multiple groups of through holes 11a in the circumferential direction of the framework 11 correspond to a plurality of blades 12, that is, each blade 12 corresponds to a group of through holes 11a. Since each group of through holes 11a has a plurality along the axial direction of the framework 11, the flow rate of the air flow flowing outwards in the first air duct 101 can be increased, and the air outlet efficiency of the second air duct 102 can be improved.

[0045] In the above technical solution, the blade 12 is fixed to the framework 11 by the cooperation of the hook 121 and the through hole 11a. Thus, the installation or disassembly of the blade 12 and the framework 11 can be realized, and the connection method is relatively simple and easy to operate, which is beneficial to the subsequent repair and disassembly. The hook 121 is adaptively clamped with a plurality of through holes 11a, which can effectively utilize the through holes 11a for air flow, and there is no need to provide separate clamping holes on the framework 11, which can reduce the mold opening difficulty or manufacturing process, thereby being beneficial to reducing the manufacturing cost. In addition, the hook 121 can pass through the through hole 11a, so that a part of the hook 121 is located in the first air duct 101, which is easy to observe and operate and convenient for the disassembly of the blade 12 and the framework 11.

[0046] In some embodiments of the present invention, as Figure 2 and Figure 3 shown, the framework 11 is provided with an embedding groove 11b, and the blade 12 is provided with a protruding portion 12a, and the protruding portion 12a is embedded in the embedding groove 11b.

[0047] The shapes of the embedding groove 11b and the protruding portion 12a can be adapted to each other, and can include but are not limited to circular, square, etc. Since the blade 12 is clamped on the skeleton 11 through the hook 121, on this basis, through the nested cooperation of the protruding portion 12a and the embedding groove 11b, the connection reliability between the blade 12 and the skeleton 11 can be further improved, the probability of the blade 12 loosening during the air outlet of the second air duct 102 can be reduced, which is beneficial to improving the stability of the air flow in the second air duct 102.

[0048] In some embodiments of the present invention, such as Figure 2 and Figure 3 shown, the embedding groove 11b and the protruding portion 12a extend along the axial direction of the skeleton 11. It can be understood that the embedding groove 11b can refer to a strip-shaped groove, and the protruding portion 12a can be a strip-shaped rib. Thus, the protruding portion 12a and the embedding groove 11b have a larger contact surface, and the binding effect after the two cooperate is stronger, so as to further improve the connection reliability between the blade 12 and the skeleton 11.

[0049] In some embodiments of the present invention, such as Figure 2 and Figure 3 shown, the skeleton 11 can include a cylindrical portion 111, a connecting rod 112, and a partition plate 113. There are two cylindrical portions 111, and they are arranged at intervals; the connecting rod 112 is arranged between the two cylindrical portions 111 and connects the two cylindrical portions 111. There are multiple connecting rods 112, and they are arranged at intervals along the circumferential direction of the cylindrical portion 111; a plurality of partition plates 113 are arranged between any adjacent two connecting rods 112. The plurality of partition plates 113 are arranged at intervals along the length direction of the connecting rod 112, and a through hole 11a is formed between any adjacent two partition plates 113.

[0050] In the above technical solution, in the skeleton 11 composed of the cylindrical portion 111, the connecting rod 112, and the partition plate 113, since adjacent two connecting rods 112 are connected by a plurality of partition plates 113, thus while having more through holes 11a and higher ventilation efficiency, the structural strength and stiffness of the entire skeleton 11 can also be improved, which is beneficial to reducing the probability of the skeleton 11 being damaged when it falls, so as to extend the service life of the skeleton 11.

[0051] In some embodiments of the present invention, such as Figure 1 and Figure 2 shown, the blade 12 has a bent portion 12b, and the bent portion 12b and the connecting rod 112 jointly define a second air duct 102. Since the blade 12 is connected to the skeleton 11, through the above solution, a relatively narrow second air duct 102 can be formed between the bent portion 12b and the outer side surface of the connecting rod 112, which is beneficial to enhancing the air outlet speed and air outlet effect of the second air duct 102.

[0052] In some embodiments of the present utility model, such as Figure 1 and Figure 2 shown, the blade 12 is provided with a hook 121. At least one of the multiple through holes 11a between any two adjacent connecting rods 112 can form a clamping hole that cooperates with the hook 121. A limiting plate 114 is arranged in the clamping hole. The limiting plate 114 is connected to two adjacent partition plates 113. The hook 121 can pass through the clamping hole and abut against the limiting plate 114.

[0053] The limiting plate 114 can abut against the hook 121 to fix the hook 121, thereby improving the connection reliability between the blade 12 and the framework 11. With this solution, the structure of the clamping hole is relatively simple and easy to manufacture.

[0054] In some embodiments of the present utility model, such as Figure 2 shown, there are multiple hooks 121, which are arranged at intervals along the length direction of the blade 12. The length direction of the blade 12 can refer to Figure 6 the front-back direction. By arranging multiple hooks 121 on the blade 12, multiple positions of the blade 12 can be fixed to the framework 11, thereby improving the connection reliability between the blade 12 and the framework 11.

[0055] In some embodiments of the present utility model, such as Figures 1 to 3 shown, the connecting rod 112 is provided with an embedding groove 11b, which extends along the length direction of the connecting rod 112. The blade 12 is provided with a protruding portion 12a, which extends along the length direction of the blade 12. The protruding portion 12a is embedded in the embedding groove 11b.

[0056] The length direction of the connecting rod 112 can refer to Figure 2 the front-back direction. In the above solution, the embedding groove 11b is a long strip-shaped groove. By arranging the embedding groove 11b on the connecting rod 112, the space on the connecting rod 112 can be fully utilized, which is convenient for arranging the embedding groove 11b. The length direction of the blade 12 can also refer to Figure 2 the front-back direction. The protruding portion 12a is a long strip-shaped protrusion. By cooperating with the embedding groove 11b, it has stronger connection reliability, thereby improving the connection reliability between the blade 12 and the framework 11.

[0057] Such as Figure 5 shown, the hair care device 1000 according to the embodiment of the present utility model includes a main body 200 and a hair care accessory 100. The main body 200 has an air outlet end 201; the hair care accessory 100 includes the air outlet component 10 described above. The hair care accessory 100 is connected to the air outlet end 201 so that the first air duct 101 of the air outlet component 10 is used for circulating the air flow from the air outlet end 201.

[0058] The main body 200 may refer to the main body structure of the hair care device 1000, and the main body 200 may be configured to output hot air, cold air or normal temperature air. In addition, the main body 200 may further include a handle, a control board, a battery, a heating element, etc., and the other components and operations of the main body 200 may refer to the main body structure of the hair curling device in the related art. Since these are known to those of ordinary skill in the art, they will not be described in detail here.

[0059] In the above hair care device 1000, the main body 200 can send out air flow to the air outlet component 10 through the air outlet end 201, and can form a clockwise or counterclockwise air flow outside the air outlet component 10, so as to curl the user's hair and achieve hair care.

[0060] According to the hair care device 1000 of the embodiment of the present invention, by adopting the above hair care accessory 100, since the structure of the air outlet component 10 is relatively simple and the manufacturing cost is relatively low, the production cost of the hair care device 1000 can be reduced accordingly.

[0061] In some embodiments of the present invention, as Figure 5 shown, the hair care accessory 100 further includes an adapter 20 and a plug 30. Both the adapter 20 and the plug 30 can be adaptively connected to both ends of the air outlet component 10, so that the installation positions of the adapter 20 and the plug 30 on the air outlet component 10 can be interchanged with each other, and the air outlet direction of the second air duct 102 can be switched between two opposite directions.

[0062] The adapter 20 is used to connect the main body 200 of the hair care device 1000, and the plug 30 is used to close one end of the air outlet component 10. When the air flow blown out by the main body 200 enters the first air duct 101, since one end of the air outlet component 10 is closed by the plug 30, the air flow can be blown out from the second air duct 102. The second air duct 102 can blow air in the clockwise direction or the counterclockwise direction. When the user is caring for the hair, the main body 200 blowing hot air can blow the hair in one direction to curl it.

[0063] Since both the adapter 20 and the plug 30 can be adaptively connected to both ends of the air outlet component 10, during the process of hair care, the user can remove the adapter 20 and the plug 30 from the air outlet component 10 and interchange their installation positions on the air outlet component 10. At this time, the second air duct 102 can blow air in the opposite direction to the previous one. For example, before the adapter 20 and the plug 30 are replaced and installed, the second air duct 102 blows air clockwise (see Figure 1 ), after the positions are replaced, the second air duct 102 can blow air counterclockwise (see Figure 6 ), and the air outlet component 10 blows the hair in the other direction to curl it, making the hair wavy.

[0064] In the above technical solution, both the adapter 20 and the plugging member 30 can be adaptively connected to both ends of the air outlet member 10. Thus, the installation positions of the adapter 20 and the plugging member 30 at both ends of the air outlet member 10 can be interchanged with each other, so that the air outlet direction of the second air duct 102 can be switched between two opposite directions. The structure of the hair care accessory 100 adopting this is relatively simple, which is beneficial to reducing the number of components and lowering the manufacturing cost. Moreover, when the hair care accessory 100 switches the air direction, it is easy to operate, which can reduce the usage difficulty and improve the user experience.

[0065] The other constitutions and operations of the hair care device 1000 according to the embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail here.
