[0007] A handle, connected to the wind tube. A controller is provided in the handle, and the controller is connected to the driving device. By adjusting the controller, the driving device is started / stopped, so that the fan blade starts / stops rotating;

[0008] An extension part, rotatably connected to a groove opened on the bottom surface of the handle. Under the action of an external force, the extension part is rotated out of the groove, so that the extension part forms an auxiliary support for the handle, and further enables the fan to be stably placed on a placement surface.

[0009] Preferably, a rotating base is provided in the groove. The extension part is erected on the rotating base and rotatably connected to the rotating base. Under the action of an external force, the extension part rotates around the rotating base.

[0010] Preferably, the wind tube is a cylindrical structure with openings at both ends, including an air inlet and an air outlet. When the extension part is rotated into place, the orientation of the extension part is consistent with the orientation of the air outlet of the wind tube, so that after the user places the mobile phone on the extension part, the user can watch the mobile phone content while blowing air.

[0011] Preferably, the extension part includes:

[0012] A body, rotatably connected to the groove;

[0013] The accessory is rotatably connected to the main body. When the main body rotates to the in-place position, the accessory can be rotated to a position parallel to the handle to limit the mobile phone placed by the user on the extension part.

[0028] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0030] As Figure 1 shown, a fan provided by an embodiment of the present utility model includes:

[0031] An air duct 1, in which a driving device and a fan blade connected to the output end of the driving device are provided;

[0032] A handle 2, connected to the air duct 1, and a controller is provided inside the handle 2. The controller is connected to the driving device, and by adjusting the controller, the driving device can be started / stopped, so that the fan blade starts / stops rotating;

[0033] An extension part 3, rotatably connected to a groove 23 opened on the bottom surface of the handle 2. Under the action of an external force, the extension part 3 is rotated out of the groove 23, so that the extension part 3 forms an auxiliary support for the handle 2, and thus the fan can be stably placed on a placement surface.

[0034] In this embodiment, the driving device is a driving motor, and the controller includes a control circuit, buttons, etc. A through hole is provided on the side surface of the handle 2, and the buttons of the controller arranged inside the handle 2 can protrude from the through hole for the user to operate the buttons to start / stop the fan or adjust the fan speed; the shape of the groove 23 is adapted to the shape of the extension part 3. When the user does not need to place the fan on a placement table such as a desktop, the extension part 3 can be rotated back into the groove 23 so that the groove 23 can accommodate the extension part 3.

[0035] In this application, by providing the extension part, the contact area between the fan handle 2 and the placement tabletop can be increased, and the extension part 3 can provide lateral auxiliary support for the handle 2, thereby improving the stability of the fan placed on the placement table and meeting the user's need to place the fan on the desktop for blowing.

[0036] As a preferred embodiment, a rotating base 24 is provided in the groove 23. The extension part 3 is mounted on the rotating base 24 and is rotatably connected to the rotating base 24. Under the action of an external force, the extension part 3 rotates around the rotating base 24.

[0037] In this embodiment, a partial groove 23 notch is provided on the groove 23 wall at the edge of the groove 23, and the rotating base 24 is arranged in the groove 23 notch, thereby avoiding occupying the main space of the groove 23 to ensure that the groove 23 can accommodate the extension part 3 for storage.

[0038] As a preferred embodiment, the air duct 1 is a cylindrical structure with openings at both ends, including an air inlet 11 and an air outlet 12. When the extension part 3 is rotated into place, the orientation of the extension part 3 is the same as the orientation of the air outlet 12 of the air duct 1, so that after the user places the mobile phone on the extension part 3, the user can watch the mobile phone content while blowing.

[0039] In this embodiment, the air duct 1 is a cylindrical barrel, and the fan blades are installed in the air duct 1 along the cross-section of the air duct 1. When the fan blades rotate, external air enters the air duct 1 from the air inlet 11 and blows out from the air outlet 12; when the extension part 3 is rotated into place, the user can place the fan on the tabletop, and the user can also place the mobile phone on the extension part 3 (one side of the mobile phone is placed on the extension part 3 and the other side leans against the handle 2 of the fan). Since the orientation of the extension part 3 is the same as the orientation of the air outlet 12 of the air duct 1 at this time, the screen of the mobile phone and the air outlet 12 of the fan both face the user, enabling the user to watch the mobile phone content while blowing the fan.

[0040] As a preferred embodiment, the extension part 3 includes:

[0041] A main body 31 rotatably connected in the groove 23;

[0042] The attached body is rotatably connected to the main body 31. When the main body 31 rotates to the in-place position, the attached body can be rotated to a position parallel to the handle 2 to limit the mobile phone placed by the user on the extension part 3.

[0043] Both the main body 31 and the auxiliary body are annular structures. The auxiliary body is embedded in the inner annular wall of the main body 31 and is rotatably connected to the inner annular wall.

[0044] In this embodiment, the attached body is in the same plane as the main body 31 before rotation, so as to facilitate the common storage of the two in the groove 23; the attached body can be rotated to a position with an angle of 0 to 90 degrees with respect to the plane where the main body 31 is located to limit the mobile phone placed on the extension part 3 at different inclinations to prevent the mobile phone from slipping.

[0045] As a preferred embodiment, the handle 2 includes:

[0046] A holding member 21, which is a cylindrical structure, is connected to the air duct 1 at one end. The holding member 21 is used for the user to hold the fan.

[0047] An embedding member 22, including a substrate 221 and an embedding body 222. The groove 23 is opened on the bottom surface of the substrate 221; the shape of the embedding body 222 is adapted to the inner space shape of the holding member 21. The embedding member 22 is embedded through the embedding body 222 from the opening at the other end of the holding member 21. The area of the substrate 221 is larger than the area of the opening at the other end of the holding member 21. When the embedding body 222 is embedded in place, the substrate 221 just abuts against the opening wall of the holding member 21.

[0048] In this embodiment, when the embedding body 222 is embedded in place, the substrate 221 just abuts against the opening wall of the holding member 21, that is, even after the embedding member 22 is embedded in the holding member 21, only the substrate 221 of the embedding member 22 is just exposed as the bottom panel of the handle 2. In this embodiment, through the nested design of the holding member 21 and the embedding member 22, the replacement of the embedding member 22 can be facilitated to change the bottom surface shape of the handle 2.

[0049] As a preferred embodiment, the cross-section of the holding member 21 is a symmetry plane, so that the embedding member 22 can be taken out from the holding member 21 along the axis of the holding member 21 and rotated by a set angle and then embedded in the holding member 21 along the axis.

[0050] In this embodiment, the cross-section of the holding member 21 can be circular, square, or oval; the set angle is set according to the shape of the cross-section. For example, when the shape of the cross-section is oval, the set angle is 180 degrees, and when the shape of the cross-section is square, the set angles are 90 degrees, 180 degrees, and 270 degrees. In this embodiment, the embedding member 22 can be embedded in the holding member 21 at different relative angles (axial center angles), and thus the relative orientation of the extension part 3 at the bottom of the embedding member 22 and the air duct 1 when rotated to the in-place position can be changed.

[0051] As a preferred embodiment, the hair dryer 1 is rotatably connected to the holding member 21. When the orientation of the extension part 3 after the embedding member 22 is embedded in the holding member 21 and rotated into place is the same as the orientation of the air suction port 11 of the hair dryer 1, under the action of an external force, the hair dryer 1 rotates to make the air suction port 11 face the extension part 3, and the driving device is started so that the air suction port 11 absorbs heat from the mobile phone placed on the extension part 3.

[0052] In this embodiment, an inner groove 23 is also formed at the top of the handle 2, and the hair dryer 1 is rotatably connected to the inner concave wall; when the orientation of the extension part 3 after the embedding member 22 is embedded in the holding member 21 and rotated into place is the same as the orientation of the air suction port 11 of the hair dryer 1, that is, when the embedding member 22 is taken out of the holding member 21, rotated 180 degrees around the axis and then reinstalled into the holding member 21, the user can place the mobile phone on the extension part 3 and apply force to the hair dryer 1 at the same time to make the hair dryer 1 rotate, so that the air suction port 11 is directly opposite to the mobile phone placed on the extension part 3 to absorb heat from the mobile phone.

[0053] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
