[0002] In daily life, as a common electrical appliance, the fan is widely used in scenarios such as indoor cooling and ventilation. Traditional fans usually have two main forms: floor fans and wall-mounted fans. The floor fan has a stable support structure and can be conveniently placed on the ground, suitable for large spaces such as living rooms and bedrooms. However, it occupies a large space and is inconvenient to use in some environments with limited space. The wall-mounted fan saves space by being installed on the wall and is especially suitable for small areas such as kitchens and bathrooms. However, the installation and disassembly of the wall-mounted fan are relatively complex, and once installed, the position is fixed, resulting in poor flexibility. In some less developed overseas regions, users may only be able to purchase single-function fans. When space savings are needed, users may hope to convert a floor fan into a wall-mounted fan for use, but currently, there is a lack of fan products on the market that can easily achieve such a conversion.

[0058] Referring to Figure 8 As shown, a soft rubber 111 for buffering is provided between the outer edge of the display touch module 200 and the fan cover 110. The soft rubber 111 can effectively absorb the vibration generated during the operation of the fan blades and the driving motor, reduce noise, and at the same time protect the display touch module 200 from mechanical impact and extend its service life.

[0059] Referring to Figure 11As shown, the drive motor 120 includes a mounting shaft 121, a stator structure 122 sleeved on the mounting shaft 121, and a rotor structure 140 sleeved outside the stator structure 122, and the fan blades 130 are sleeved on the periphery of the rotor structure 140. The fixed bracket 210 is fixedly connected to the end of the mounting shaft 121. The drive motor 120 is the core power component of the fan, which realizes power output through the mounting shaft 121, the stator structure 122 and the rotor structure 140, drives the fan blades 130 to rotate, thereby generating airflow. As can be seen from the figure, the drive motor can adopt a DC brushless motor, and its fan blades are not connected to the transmission shaft of the motor center through the motor shaft like a traditional fan, but the rotor part of the drive motor is located at the outer ring part of the stator, and the fan blades are located at the outermost ring of the rotor part, which is thinner than the existing fan head, and the thickness of the stacked assembly combined with the display touch module is not increased relative to the existing fan, and does not affect the use of the fan as a whole.

[0060] Continue to refer to Figure 12 As shown, the rotor structure 140 includes a rotor 141 and a motor housing 142 installed outside the rotor 141. The fan blades 130 are threadedly connected to the mounting shaft 121 through a fixing block 139, which is convenient for users to disassemble the fixing block to clean the fan blades or perform maintenance.

[0061] In some embodiments, a gasket is provided between the fixing block 131 and the fan blade 130 to make the threaded connection between the fixing block and the fan blade more secure.

[0062] Reference Figure 8 As shown, the motor housing 142 is arranged corresponding to one side of the fixed bracket 210, and a heat dissipation gap 149 is provided between the motor housing 142 and the fixed bracket 210.

[0066] Continue to refer to Figures 13 to 14 As shown, the rechargeable battery 800 provides power support for the fan, enabling the fan to operate normally without mains power. The rechargeable battery 800 can be a lithium battery or a lead-acid battery. Lithium batteries have the advantages of small size, light weight, fast charging speed, etc., and are suitable for users with higher requirements for portability; lead-acid batteries have the characteristics of lower cost and higher reliability, and are suitable for users who are more sensitive to cost. The rechargeable battery 800 is electrically connected to the mains plug 810 through the power supply line 900. When mains power is available, the rechargeable battery 800 can be charged through the mains plug 810, which is convenient and fast.

[0067] The power supply line 900 transmits the power of the rechargeable battery 800 to the fan body, enabling the fan to operate normally. A first electrical connection head 310 is provided at the end of the power supply line 900, and the first electrical connection head 310 is detachably connected to the power supply interface 180, so that the user can conveniently replace the rechargeable battery 800 according to needs, improving the flexibility of use of the fan.
