They do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure, and should not be understood as a limitation of the present invention.

[0054] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0055] The utility model provides a rotary hair dryer which is suitable for application scenarios of drying or combing hair, and can effectively solve the problem that the existing hair dryers cannot have both the functions of drying and combing hair.

[0056] See also Figure 1 and Figure 2 In this embodiment, the rotary hair dryer includes a rotating member 1, an air outlet assembly 2, a plurality of comb teeth 3, and a hair dryer body 6.

[0057] See also Figure 5 The rotating member 1 is rotatably connected to the hair dryer body 6, and an air supply cavity 101 is provided inside the rotating member 1. The hair dryer body 6 is also provided with a receiving cavity 601 connected to the air supply cavity 101, and an air inlet hole 602 connected to the receiving cavity 601 is provided at one end of the hair dryer body 6 away from the air outlet assembly 2.

[0058] A fan assembly 4 for supplying air to the air supply cavity 101 is disposed in the accommodating cavity 601 , and an inlet of the air supply assembly is disposed close to the air inlet hole 602 , and an outlet of the air supply assembly is disposed close to the air outlet assembly 2 .

[0059] The circumferential surface of the rotating member 1 is provided with a connecting window 102 connecting the air supply cavity 101 to the external space of the rotating member 1. The air outlet assembly 2 is tightly connected to the hair dryer body 6 and is rotatably mounted on the outside of the rotating member 1; the circumferential surface of the air outlet assembly 2 is provided with a centralized air outlet 2013a and a plurality of dispersed air outlet holes 2012a. Each of the comb teeth 3 is mounted on the air outlet assembly 2 and distributed in the gaps between each of the dispersed air outlet holes 2012a.

[0060] Among them, the rotating part 1 has a centralized air supply state in which, after being driven, it rotates relative to the air outlet component 2 until the centralized air outlet 2013a is connected with the air supply chamber 101 through the connecting window 102; and has a decentralized air supply state in which, after being driven, it rotates relative to the air outlet component 2 until each decentralized air outlet hole 2012a is connected with the air supply chamber 101 through the connecting window 102.

[0061] Furthermore, a knob portion 7 is rotatably connected to the air outlet assembly 2 at one side away from the rotating member 1, and the knob portion passes through the air outlet assembly 2 and is tightly connected to the rotating member 1. By holding the hair dryer body 6 and twisting the knob portion 7, the rotating member 1 can be rotated relative to the air outlet assembly 2.

[0062] In the rotary hair dryer provided in this embodiment, the rotating part 1 can rotate relative to the air outlet component 2. When it is necessary to blow the hair, the rotating part 1 is rotated to the concentrated air supply state, and then the concentrated air outlet 2013a is directed toward the hair to blow air; when it is necessary to comb the hair, the rotating part 1 is rotated to the dispersed air supply state, and then the hair can be combed directly with the comb teeth 3. During the combing process, the wind will be blown out from each dispersed air outlet 2012a, thereby achieving the effect of combing and blowing the hair at the same time.

[0063] Therefore, the rotary hair dryer provided in this embodiment can effectively solve the problem that the existing hair dryers cannot have both the functions of blowing and combing hair.

[0064] Optionally, the size of the dispersed air outlet 2012a is smaller than that of the concentrated air outlet 2013a, so the air outlet of the concentrated air outlet 2013a is larger, which is suitable for drying hair, and the air outlet of the dispersed air outlet 2012a is small but dispersed, which is suitable for combing hair.

[0065] Furthermore, the size of the centralized air outlet 2013a gradually decreases in the direction away from the axis of the air outlet assembly 2, so as to increase the blowing speed of the centralized air outlet 2013a.

[0066] In this embodiment, the air outlet assembly 2 includes an air shield bracket 201 and a C-shaped air shield 202. Further, the air shield bracket 201 includes an annular bracket 2011 for mounting and fixing the C-shaped air shield 202, a five-piece set 2012 fixed to the outside of the annular bracket 2011, and an air collection nozzle 2013 detachably mounted on the annular bracket 2011.

[0067] Each of the dispersed air outlet holes 2012a is located on the five-piece set 2012, and the concentrated air outlet 2013a is located on the air collecting nozzle 2013. The C-shaped wind shield 202 is installed on the inner circle of the wind shield bracket 201 and is provided with a plurality of air holes 2021. Figure 3 and Figure 4 The annular bracket 2011 is provided with a small hollow groove 2011a connecting each of the dispersed air outlet holes 2012a and each of the air holes 2021, and a plurality of large hollow grooves 2011b connecting the concentrated air outlet 2013a and the notch portion 2022 of the C-shaped wind shield plate 202.

[0068] The C-shaped windshield plate 202 is rotatably mounted on the rotating member 1, and a gap space 203 is provided between the C-shaped windshield plate 202 and the windshield plate bracket 201;

[0069] See also Figure 6 When the rotating member 1 is in the centralized air supply state, the notch portion 2022 of the C-shaped wind shield 202 rotates to be arranged opposite to the connecting window 102, so that the centralized air outlet 2013a is connected to the air supply cavity 101 through the notch portion 2022 of the C-shaped wind shield 202 and the connecting window 102 in sequence;

[0070] See also Figure 7 When the rotating member 1 is in the dispersed air supply state, the notch portion 2022 of the C-shaped wind shield 202 rotates to be offset from the connecting window 102, so that each of the dispersed air outlet holes 2012a is connected to the air supply cavity 101 through each of the air holes 2021, the gap space 203, and the connecting window 102 in sequence.

[0071] Specifically, the inner wall of the windshield bracket 201 is provided with two limiting slots 2011c for axial plugging and unplugging connection with the C-shaped windshield 202; and each of the large hollow grooves 2011b is located between the two limiting slots 2011c.

[0072] The rotary hair dryer provided in this embodiment rotates the rotating member 1 to the centralized air supply state when hair needs to be blown. At this time, the connecting window 102, the notch portion 2022 of the C-shaped windshield, the large hollow grooves 2011b, and the centralized air outlet 2013a are aligned. The notch portion 2022, the large hollow grooves 2011b, and the centralized air outlet 2013a are relatively large in size. The pressure drop of the air in the air supply cavity 101 when passing through the notch portion 2022, the large hollow grooves 2011b, and the centralized air outlet 2013a is relatively small, and the air outlet is centralized, so the hair can be blown dry.

[0073] When it is necessary to comb the hair, the rotating part 1 is rotated 180° to the dispersed air supply state. At this time, the notch portion 2022, the large hollow grooves 2011b, and the concentrated air outlet 2013a are all rotated to a position away from the connecting window 102. The connecting window 102 is directly connected to the gap space 203. The wind in the air supply cavity 101 passes through the connecting window 102, the gap space 203, the ventilation holes 2021, the small hollow grooves 2011a, and the dispersed air outlet holes 2012a, and is dispersedly blown out in all directions to cooperate with the comb teeth 3 to comb the hair.

[0074] In this embodiment, a plurality of reinforcing ribs 103 arranged at intervals along the axial direction are provided at the connecting window 102 to improve the structural strength of the connecting window 102 . At this time, an air outlet window is formed between two adjacent reinforcing ribs 103 .

[0075] The fan assembly 4 is provided with an air guide 5 on one side close to the air supply cavity 101. The air guide 5 includes a plurality of arc-shaped partitions 501 arranged at intervals, and a lateral air guide channel 502 connecting the accommodating cavity 601 to the corresponding air outlet window is formed between two adjacent arc-shaped partitions 501. The air guide 5 can change the blowing direction from axial blowing to radial blowing, and the arc-shaped structural design is conducive to reducing the pressure drop.

[0076] Optionally, two spring steel ball assemblies 104 are symmetrically arranged about the axis of the rotating member 1 at the end surface of the rotating member 1; and a positioning groove 2011d for the spring steel ball assembly 104 to be inserted into is provided at the position of the air outlet assembly 2 corresponding to each of the spring steel ball assemblies 104. When rotating to the concentrated air supply state or the dispersed air supply state, the two spring steel ball assemblies 104 will be inserted into the corresponding positioning groove 2011d to limit the relative rotation between the air outlet assembly 2 and the rotating member 1.

[0077] Optionally, the air collecting nozzle 2013 is magnetically connected to the annular bracket 2011, and the air collecting nozzle 2013 is removed. At this time, the large hollow groove 2011b can be used as an air collecting outlet to blow air directly to the hair.

[0078] The rotary hair dryer provided in this embodiment has the following advantages:

[0079] ① The rotating member 1 can rotate relative to the air outlet assembly 2. When the rotating member 1 is rotated to the concentrated air supply state, the hair can be blown; when the rotating member 1 is rotated to the dispersed air supply state, the hair can be combed and blown at the same time;

[0080] ② The C-shaped windshield plate 202 is plugged and connected to the two limit slots 2011c along the axial direction, which is convenient for assembly and disassembly;

[0081] ③ The air guide 5 can change the blowing direction from axial blowing to radial blowing, and the arc-shaped structural design is conducive to reducing the pressure drop;

[0082] ④ The spring steel ball assembly 104 and the positioning groove 2011d are arranged to relatively position the rotating member 1 to ensure the stability of the rotating member 1 after switching positions.

[0083] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0084] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
