[0044] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly specified in the context, it should be understood as "one or more".

[0045] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0046] A foldable hair dryer includes a first part 1 and a second part 2.

[0047] The first part 1 includes a motor 51, a fan blade 52 driven by the motor 51, and a first housing 3 for mounting the motor 51 and the fan blade 52. The second part 2 includes a second housing 4 which has a ventilation duct 21. One end of the second housing 4 is rotatably connected to one end of the first housing 3 and can be folded to fit or tend to fit with the first part 1. Specifically, the maximum rotation angle of the second housing 4 is 160 - 180 degrees, and in this embodiment, it is 180 degrees. During the rotation of the second housing 4 relative to the first housing 3, one end of the ventilation duct 21 is always in communication with the area of the first housing 3 where the fan blade 52 is installed.

[0048] Specifically, the first housing 3 includes a handle portion 31 and mounting end plates 32 fixed relative to the handle portion 31. The handle portion 31 is a triangular structure with a hollow middle. Two mounting end plates 32 are symmetrically arranged, and there are air inlets 321 on the mounting end plates 32. The connection between the mounting end plates 32 and the handle portion 31 can be integrally formed or connected together by an assembly method, such as through snap - fits. Finally, the mounting end plates 32 and the handle portion 31 can be understood as a fixed structure and do not move relative to each other. The second housing 4 includes an annular cylinder 41 and an air outlet cylinder 42. An opening is provided on the side wall of the annular cylinder 41. One end of the air outlet cylinder 42 is connected to the opening of the annular cylinder 41. The two ends of the annular cylinder 41 are in a through state and are respectively rotatably connected to the two mounting end plates 32. External air enters the annular cylinder 41 from the air inlets 321 on the mounting end plates 32 and then is ejected from the opening through the air outlet cylinder 42. The motor 51 is an outer - rotor motor 51, the fan blade 52 is mounted on the outer rotor, the motor 51 is located inside the annular cylinder 41, and the inner stator of the motor 51 is fixed to the mounting end plate 32.

[0049] To ensure that external air enters the annular cylinder 41 as evenly as possible through the air inlets 321 of the mounting end plates 32, a sealing structure is provided between the mounting end plates 32 and the annular cylinder 41. The sealing structure is generally an O - ring, and one or more O - rings can be provided according to the situation. Since the sealing of this product in this application does not require absolute sealing, the clearance between the two can also be controlled. Both ends of the annular cylinder 41 form guide rings 411, and the guide rings 411 extend towards the inside of the annular cylinder 41 and the diameter gradually decreases. In this way, the air directly enters the annular cylinder 41 and then is discharged from the opening, and air leakage from the gap between the annular cylinder 41 and the mounting end plates 32 is avoided as much as possible. This can be achieved only by controlling the clearance and the guide rings 411 without setting O - rings.

[0050] The air outlet cylinder 42 includes at least two cylinder segments 421, and adjacent cylinder segments 421 are spliced through a connection structure. In this example, three cylinder segments 421 are provided. There are many forms of the connection structure, and the main purpose is to change the length of the air outlet cylinder 42 and replace the air outlet with different shapes (such as a flat outlet, a square outlet, etc.) to adapt to different working conditions.

[0051] This embodiment mainly introduces two connection structures. The connection structure includes a buckle 61 located on one of the barrel segments 421 and a hook portion 64 located on the other barrel segment 421. The buckle 61 always has a tendency to move towards the hook portion 64 and hooks on the hook portion 64 when no external force is applied.

[0052] The tendency of the buckle 61 can be formed in two ways. One way is that the buckle 61 itself is made of an elastically deformable material, such as elastic plastic. In this case, the buckle 61 is integrally formed with the barrel segment 421. Another way is to install an elastic member 63 on the buckle 61. The elastic member 63 can be a torsion spring or a spring. When the elastic member 63 is installed, the buckle 61 is rotatably connected to the barrel segment 421 through a rotating shaft 62. In this embodiment, a spring is taken as an example. One end of the spring is connected to the buckle 61, and the other end is connected to the barrel segment 421. The spring can be a compression spring or a tension spring, and the type selected depends on which side of the rotating shaft 62 the spring is located. In this embodiment, the spring is a compression spring and is located on the side of the rotating shaft 62 away from the hook portion.

[0053] The first barrel segment 421 and the second barrel segment 421 are connected in the above manner.

[0054] The second way of the connection structure is: The connection structure includes a clamping portion 71 located on one of the barrel segments 421 and a clamping groove 72 located on the other barrel segment 421. The clamping groove 72 is an annular groove and is located on the second barrel segment 421; the clamping portion 71 is a clamping hook and is evenly distributed in four along the circumferential direction and is located on the third barrel segment 421. Quick connection or disassembly is achieved through clamping. This method requires a certain amount of force when disassembling. The second barrel segment 421 and the third barrel segment 421 are connected in the above manner.

[0055] In order to facilitate the installation of the second housing 4, both the air outlet barrel 42 and the annular barrel 41 can be spliced into a structure of two halves, or a local splicing and local integral method can be adopted.

[0056] In order to accelerate the air outlet speed, an air supplement port 422 is provided on the side wall of the air outlet barrel 42. The air supplement port 422 is specifically located at the connection between the second barrel segment 421 and the third barrel segment 421. The air inlet 321 is communicated with the ventilation duct 21. When the air is discharged from the ventilation duct 21, a negative pressure will be formed, and the external air will enter from the air supplement port 422. At this time, the externally supplemented air and the air in the ventilation duct 21 will converge and be discharged from the end of the air outlet barrel 42, and the air outlet volume is larger.

[0057] The foldable hair dryer further includes a locking structure for locking the second housing 4 after it rotates relative to the first housing 3.

[0058] The lock structure includes a first limiting portion 83 located on the first housing 3, a second limiting portion 84 located on the second housing 4, and a control member for controlling the separation or cooperation and limitation of the first limiting portion 83 and the second limiting portion 84. The control member includes a control button 81 located on the first housing 3 or the second housing 4, and an elastic reset member 82 connected to the control button 81. The first limiting portion 83 or the second limiting portion 84 is connected or integral with the control button 81.

[0059] In this embodiment, the control button 81 is rotatably mounted on the handle portion 31 through a mounting shaft 85. The elastic reset member 82 is a compression spring. One end of the compression spring is connected to the control button 81, and the other end is connected to the handle portion 31. Wherein the elastic reset member 82 can also be a torsion spring. The first limiting portion 83 is a convex structure integrally formed with the control button 81. The second limiting portion 84 is a limiting groove 842 located on the annular cylinder 41. Specifically, the limiting groove 842 is formed by arranging a plurality of protruding portions 841 at intervals on the outer wall of the annular cylinder 41. A limiting groove 842 is formed between two adjacent protruding portions 841. When the control button 81 is not stressed, due to the reset action of the compression spring, the first limiting portion 83 is snapped into the second limiting portion 84, and the annular cylinder 41 cannot rotate relative to the handle portion 31, that is, the second housing 4 and the first housing 3 are in a locked state. When the control button 81 is pressed, the control button 81 rotates so that the first limiting portion 83 moves away from the second limiting portion 84. At this time, the compression spring is compressed, and the second housing 4 can be rotated.

[0060] Wherein, a battery 9 and a control button 81 are also mounted on the handle portion 31. The control button 81, the battery 9, and the motor 51 are connected in series electrically. When the second housing 4 rotates 180 degrees, it abuts against the battery 9.

[0061] Embodiment 2: The difference from Embodiment 1 is that the lock structure is different. The lock structure in this embodiment includes a first limiting portion 83 located on the first housing 3 and a second limiting portion 84 located on the second housing 4. The first limiting portion 83 and the second limiting portion 84 are at least mutually limited when locked, and the first limiting portion 83 and the second limiting portion 84 at least include an elastic structure. This method relies on the friction force between the first limiting portion 83 and the second limiting portion 84 to achieve rotation and positioning, and the second housing 4 needs to overcome the friction force during the rotation process relative to the first housing 3. Specifically, as Figure 10 , the first limiting portion 83 can be an elastic structure, which is a rubber block, and three can be provided; the second limiting portion 84 of the annular cylinder 41 is an annular strip structure, and the second limiting portion 84 and the annular cylinder 41 can be integrally formed. However, in order for the second limiting portion 84 to be more wear-resistant, it can be a stainless steel ring, adhesively bonded to the annular cylinder 41. The first limiting portion 83 is always in contact with the second limiting portion 84. Since the first limiting portion 83 will be worn, therefore, the first limiting portion 83 is preferably installed in a snap-fit manner so as to replace the first limiting portion 83.

[0062] Embodiment 3: Regarding the positions of the first limiting portion 83 and the second limiting portion 84 in Embodiment 1 and Embodiment 2, the second limiting portion 84 can also be arranged at the end of the annular cylinder 41, for example, arranged on the air guide ring 411. The corresponding first limiting portion 83 can be installed on the installation end plate 32.

[0063] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above utility model concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) having similar functions disclosed in the embodiments of the present disclosure.
