[0031] Embodiment 1.

[0032] Embodiment 1 discloses a folding handle. In this embodiment, the folding handle can be used for a hair dryer. Of course, the folding handle can also be applied to other electrical appliances or other daily necessities that need to be folded and stored, such as electric fans or flashlights. When in the open state, it is in use, and when in the folded state, the volume is reduced, which is convenient for storage.

[0033] Figure 1 Schematic diagram of the installation position of the rotating structure in the folding handle in the embodiment of the utility model. Figure 1 As shown, the folding handle includes a main body component 1, a handle component 2 and a rotating structure 3. The handle component 2 includes a first inclined surface 201. The rotating structure 3 is fixedly connected to the main body component 1 and includes a second inclined surface 301. The second inclined surface 301 has the same area as the first inclined surface 201, and they are in contact, attached and connected to each other.

[0034] Figure 2 FIG. 1 is a schematic diagram of a foldable handle in an embodiment of the present utility model. Figure 2 As shown, the second inclined surface 301 can rotate around the rotation axis 4 relative to the first inclined surface 201 , and the rotation axis 4 is perpendicular to the first inclined surface 201 and the second inclined surface 301 .

[0035] Specifically, the handle assembly 2 can be regarded as cylindrical or truncated cone, and the angle between the rotation axis 4 and the axis of the handle assembly 2 can be in the range of 40° to 50°. The specific value of the angle between the rotation axis 4 and the central axis of the handle assembly 2 is affected by the inclination angles of the first inclined surface 201 and the second inclined surface 301. It is necessary to ensure that there is no volume interference between the handle assembly 2 and the main body assembly 1 during rotation to affect the rotation process. It is also affected by factors such as the outer surface shape of the cylindrical handle assembly 2. For example, if the handle assembly 2 is a standard cylinder or a truncated cone with a thick top and a thin bottom, the angle will be different, but it will not affect the rotation of the handle assembly 2 and the main body assembly 1 to an unfolded state or a folded state.

[0036] When the angle between the rotation axis 4 and the central axis of the handle assembly 2 is 45°, when the second inclined surface 301 rotates to the first state relative to the first inclined surface 201, the handle assembly 2 and the main body assembly 1 are perpendicular to each other. When the second inclined surface 301 rotates to the second state relative to the first inclined surface 201, the handle assembly 2 and the main body assembly 1 are parallel to each other. Figure 2 Shown is a schematic diagram of a first state of the folded handle. Figure 3 FIG. 2 is a schematic diagram of another state of the folding handle in the embodiment of the utility model. Figure 3 In the first state, the main body component 1 and the handle component 2 are in an open state, and in the second state, the main body component 1 and the handle component 2 are in a folded state, the volume is reduced, and can be used for storage.

[0037] The rotating structure 3 is fixed to the main assembly 1. Figure 1 As shown, in this embodiment, the main body assembly 1 includes a main body outer cylinder 101, and the side wall of the main body outer cylinder 101 is provided with an outer cylinder side wall extension cylinder 105 perpendicular to the section of the side wall of the main body outer cylinder 101. The side of the rotating structure 3 is fixed in the outer cylinder side wall extension cylinder 105.

[0038] Figure 4 It is a schematic diagram of the rotating structure in the embodiment of the utility model. Figure 5 FIG. 1 is a schematic diagram of a handle assembly in an embodiment of the present utility model. Figure 4 and Figure 5 As shown, the folding handle further includes a positioning structure; the positioning structure includes an elastic arm 204, the first end of the elastic arm 204 is fixed to the handle assembly 2, and the second end of the elastic arm 204 protrudes from the plane where the first inclined surface 201 is located. The positioning structure also includes at least two notches 304, which are opened on the rotating structure 3. When the second inclined surface 301 rotates relative to the first inclined surface 201 to the positioning state, the second end of the elastic arm 204 is embedded in the notch 304. In this embodiment, there are two notches 304, and the positioning state refers to Figure 2 The first state shown and Figure 3The second state shown. The opening position of the notch 304 corresponds to the relative position of the handle assembly 2 and the main body assembly 1 in the positioning state. Specifically, when the main body assembly 1 together with the rotating structure 3 rotates to the first state relative to the handle assembly 2, the second end of the elastic arm 204 is stuck in a notch 304, and when the main body assembly 1 together with the rotating structure 3 rotates to the second state relative to the handle assembly 2, the second end of the elastic arm 204 is stuck in another notch 304. During the rotation process between the first state and the second state, the elastic arm 204 elastically contracts and is stuck by the second inclined surface 301 below the plane where the first inclined surface 201 is located. After the handle assembly 2 is rotated to the positioning structure, there will be a corresponding feeling of the elastic arm 204 popping out after rotating into place.

[0039] like Figure 4 , Figure 5 As shown, further, the first inclined surface 201 and the second inclined surface 301 are connected together by an annular fixing structure. The annular fixing structure includes a connecting hole 202 and a connecting column 302 respectively fixed to the first inclined surface 201 and the second inclined surface 301. In this embodiment, the connecting hole 202 is opened on the first inclined surface 201, and the connecting column 302 is arranged on the second inclined surface 301. It is easy to understand that the connecting hole 202 can also be arranged on the second inclined surface 301, and the connecting column 302 can also be arranged on the first inclined surface 201.

[0040] In this embodiment, an annular fixing groove 203 is provided on the inner wall of the connection hole 202; a fixing ring 303 for embedding in the fixing groove 203 is provided on the outer wall of the connection column 302. When installing, the connection column 302 is inserted into the connection hole 202, and the fixing ring 303 is embedded in the fixing groove 203, so that the first inclined surface 201 and the second inclined surface 301 are connected together, and the first inclined surface 201 can rotate relative to the second inclined surface 301. Similarly, an annular fixing groove 203 can also be provided on the outer wall of the connection column 302, and a fixing ring 303 for embedding in the fixing groove 203 can be provided on the inner wall of the connection hole 202.

[0041] Embodiment 2.

[0042] The second embodiment discloses a hair dryer. The hair dryer of the second embodiment uses the folding handle disclosed in the first embodiment. In this embodiment, the hair dryer is an electric hair dryer.

[0043] Figure 6 It is a cross-sectional view of the blowing device in the embodiment of the utility model. Figure 7 FIG. 2 is a cross-sectional view of another state of the blowing device in the embodiment of the utility model. Figure 6 , Figure 7As shown, in the hair dryer, the main body assembly 1 includes an air outlet channel 103. The handle assembly 2 is provided with an air inlet channel 207, and the air outlet of the air inlet channel 207 is provided on the second inclined surface 301. The rotating structure 3 includes an intermediate channel 305, and the air inlet of the intermediate channel 305 is provided on the first inclined surface 201. The air inlet channel 207, the intermediate channel 305 and the air outlet channel 103 are all connected to each other. Figure 6 and Figure 7 As shown, after the rotating structure 3 is set, when the blowing device is in Figure 6 In the unfolded state shown, the air outlet of the blowing device is not affected. The rotation axis 4 is located at the center of the air inlet of the middle channel 305 of the first inclined surface 201, and is also located at the center of the air outlet of the air inlet channel 207 of the second inclined surface 301. During the rotation process, the air duct space in which the air inlet channel 207, the middle channel 305 and the air outlet channel 103 are interconnected also remains sealed and does not leak air. Further, a motor assembly 206 is installed in the handle assembly 2. The motor assembly 206 includes a motor and an impeller, and is installed at the air inlet end of the air inlet channel 207. The wind generated by the motor assembly 206 can be blown out through the air inlet channel 207, the middle channel 305 and the air outlet channel 103 in sequence.

[0044] Furthermore, a heating module 102 is installed in the main component 1, and the heating module 102 is arranged around the air outlet channel 103, so that the air blown out can be controlled to be hot air.

[0045] Figure 8 This is an exploded view of the blowing device in the embodiment of the utility model. Figure 6 to Figure 8 The heating module 102 is installed in the main body outer cylinder 101, and the main control board 104 and the main body movement assembly are also installed in the main body outer cylinder 101. The handle assembly 2 also includes two handle frames 209 installed in the handle outer cylinder 205, and the two handle frames 209 are combined to form the main supporting structure of the handle assembly 2. The first end of the elastic arm 204 is fixed to the side of one of the handle frames 209, close to the position 201 of the first inclined surface, to ensure that the second end of the elastic arm 204 protrudes from the plane where the first inclined surface 201 is located. An air inlet net 208 is also installed at the lower end of the handle outer cylinder 205. An air inlet assembly 210 is installed at the lower end of the motor assembly 206.

[0046] In this embodiment, when the blowing device is in Figure 6In the state shown, the elastic arm 204 is in a positioned state after being inserted into one of the notches 304. When the motor assembly 206 starts to work, the motor rotates to drive the impeller to rotate, sucking the flowing air from the air inlet net 208, entering the air inlet channel 207 through the air inlet assembly 210 and the motor assembly 206, and then passing through the middle channel 305 in the rotating structure 3, and finally entering the cavity in the main assembly 1, passing through the heating module 102 and then being blown out through the air outlet channel 103. After use, the main assembly 1 is rotated to rotate relative to the handle assembly 2 to become Figure 7 In the state shown, during the rotation process, the elastic arm 204 is pressed into the plane below the first inclined surface 201 by the second inclined surface 301 until the elastic arm 204 pops out and snaps into another notch 304 after the rotation, and the hair dryer becomes a folded state suitable for storage.

[0047] Furthermore, in order to ensure that the rotating part of the rotating structure 3 does not leak air, Figure 8 As shown, the annular fixing structure further includes an annular sealing member 306 , which is sleeved on the connecting column 302 and is interference fit with the inner wall of the connecting hole 202 . Fig. 9 for Figure 8 The enlarged schematic diagram of part A in FIG. Fig. 9 As shown, a sealing platform 211 is provided on the inner wall of the connecting hole 202, and a sealing member 306 can be placed on the sealing platform 211. When the connecting column 302 is assembled in the connecting hole 202, the sealing member 306 can seal the installation position of the connecting column 302 and the connecting hole 202 to prevent air leakage, and can further prevent air leakage in the air duct, so that the rotation between the handle assembly 2 and the main body assembly 1 does not affect the sealing of the entire air duct.

[0048] exist Fig. 9 The position of the fixing groove 203 is also shown in FIG. Figure 4 It can be seen that when the connecting column 302 is assembled in the connecting hole 202 , the fixing ring 303 is embedded in the fixing groove 203 .

[0049] In the hair dryer disclosed in this embodiment, the motor assembly 206 is arranged in the handle assembly 2, the length of the wind tube portion of the main assembly 1 is reduced, and the handle assembly 2 can also be rotated and folded relative to the main assembly 1, further reducing the volume of the entire hair dryer for easy storage.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
