[0026] Detailed Implementation

[0027] To better understand the technical solution of this utility model, the embodiments provided by this utility model are described in detail below with reference to the accompanying drawings.

[0028] The above provides a detailed description of a fan provided by the embodiments of this utility model. For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.

[0029] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "middle", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] The present invention aims to provide a fan with a more compact structure and smaller size. Compared with the prior art, the fan provided by the present invention does not have a fan body, making it more convenient to carry.

[0032] like Figures 1 to 8 As shown, this utility model embodiment provides a fan, such as... Figure 1-2 As shown, it includes a shell 1, which is a hollow cylindrical structure. In a preferred embodiment, the shell 1 is the handle that the user holds when in use. In the prior art, most handheld fans are composed of a fan body and a handle, which is inconvenient to carry. However, the fan of this utility model has a cylindrical structure, which is more compact and more convenient for the user to carry.

[0033] The outer casing 1 is divided into a front end and a rear end. The rear end of the outer casing 1 is constructed with an integrated mesh cover 11, on which an air inlet 12 is provided. A support 2 is installed at the bottom of the outer casing 1, and a first air outlet 21 for ventilation is opened on the support 2. An air supply assembly 3 is installed inside the support 2. The air supply assembly consists of a fan blade 31 and a motor 32. When the air supply assembly 3 is in operation, it draws outside air into the inside of the outer casing 1 along the air inlet 12 and the first air outlet 21.

[0034] like Figure 3 The inner side of the bracket 2 is provided with a first power fixing position 22 for fixing the power supply 51. The first power fixing position 22 is provided with an annular mounting groove, and the power supply 51 is embedded in the mounting groove during installation.

[0035] like Figure 4-5 The outer casing 1 has a fan cover 4 at its front end. A second air outlet 41 is provided on the outer side of the fan cover 4, allowing air drawn in by the air supply assembly 3 to be blown out to the outside through the second air outlet 41. A second power supply fixing position 42 is provided on the inner side of the fan cover 4, corresponding to a first power supply fixing position 22. During assembly, the power supply 51 is fixed to both the second power supply fixing position 42 and the first power supply fixing position 22, which together secure the power supply 51. Furthermore, since the second power supply fixing position 42 and the first power supply fixing position 22 are located in the central part of the outer casing 1, after the power supply 51 is fixed to these positions, it will be located in the center of the outer casing 1, between the outer side of the power supply 51 and the inner side of the outer casing 1. This means that a ventilation duct 13 is constructed on the outer side of the power supply 51. The air duct 13 is connected to the air inlet 12. When the air supply assembly 3 is working, outside air enters from the air inlet 12 and flows along the first air outlet 21 and the air duct 13, and is finally blown out to the outside from the second air outlet 41. The fan is cylindrical in shape, making it more compact and easier to carry.

[0036] like Figure 6-8 In the second embodiment, a mounting position 43 is provided on the outer side of the fan cover 4, and a light-emitting device 6 is mounted on the mounting position 43. A lampshade 61 is fastened to the outer side of the light-emitting device 6. The light-emitting device 6 is electrically connected to the internal power supply 51. In the third embodiment, a semiconductor cooling element 7 is mounted on the mounting position 43 of the fan cover 4, and a heat sink 71 is mounted on the inner side of the fan cover 4. The heat sink 71 is used to dissipate heat from the semiconductor cooling element 7. A face mask cover 72 is also mounted on the outer side of the semiconductor cooling element 7. When the semiconductor cooling element 7 is working, it lowers the temperature of the face mask cover 72, making the face mask cover 72 feel cool. The user can put the face mask cover 72 on the skin to make the body cooler. In yet another embodiment, a button and a charging port are provided on the fan cover 4. Therefore, in multiple embodiments of this utility model, the button 52, charging port 53, semiconductor cooling element 7, and other components can be selectively mounted on the panel 5 or the fan cover 4.

[0037] like Figure 1-2The outer casing 1 has a panel mounting position 14, a panel 5 is mounted on the panel mounting position 14, a button 52 and a charging port 53 are mounted on the panel 5, and a control motherboard 54 is fixed on the panel 5, and the various electronic components are electrically connected to each other.

[0038] A rotatable support leg 8 is provided at one end of the panel 5. The support leg 8 is fixed to the outside of the panel 5 by a pivot. When the user needs to place the fan on the table, the support leg 8 can be rotated to support the placement of the fan. Figure 1 ,and Figure 6 A semiconductor cooling element 7 is mounted on the other end of the panel 5, and a face mask cover 72 is mounted on the outer side of the semiconductor cooling element 7. When the semiconductor cooling element 7 is working, it lowers the temperature of the face mask cover 72, which the user can place on the skin to cool down and improve the user experience. The electronic components are electrically connected to the power supply 51, and the user can control the relevant components through the button 52. In another optional embodiment, only the semiconductor cooling element 7 can be provided on the panel 5. In yet another embodiment, the panel 5 can only have the button 52 and the charging port 53.

[0039] The description of various embodiments of this utility model is for illustrative purposes only and is not intended to limit the scope of the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used in the embodiments is intended to best explain the principles of the embodiments, their practical application, or to enable others skilled in the art to understand the disclosed embodiments, and should not be construed as limiting the utility model.
