[0023] like Figures 1 to 3 As shown, a multi-functional fan that integrates heating and cooling includes a housing 1, in which a fan assembly 2 and a heating assembly 3 are integrated; an oscillating head assembly 4 is rotatably connected to the bottom of the housing 1, and a foot assembly 5 is provided at the bottom of the oscillating head assembly 4.

[0024] like Figure 3As shown, the oscillating assembly 4 includes a rotating component, a stepper motor 44, and a base 46. The base 46 is fixed to the top of the stand assembly 5, and the stepper motor 44 is fixed to the top of the base 46. The stepper motor 44 drives the rotating component to rotate, and the rotating component is fixedly connected to the outer shell 1. The rotating component includes a damping shaft 41, a rotating base 42, a rotating cover 43, and a gear 45. The output shaft of the stepper motor 44 drives the rotating cover 43 through the gear pair 45. The rotating cover 43 is rigidly connected to the rotating base 42, and the top of the rotating base 42 is coupled to the outer shell 1 via the damping shaft 41. In this embodiment, the rotational motion of the motor is converted into the reciprocating oscillation of the outer shell 1 through the above-described transmission system, thus realizing the fan oscillation function.

[0025] The tripod assembly 5 includes a fixed connector 51, three fixed rods 52, and a support frame. The fixed connector 51 is located at the bottom of the oscillating head assembly 4 and is fixedly connected to the oscillating head assembly 4. The fixed rods 52 are fixed to the bottom of the fixed connector 51, and the support frame is fixed inside the three fixed rods 52. The bottom of the fixed rods 52 is provided with a foot 54, and the foot 54 has anti-slip stripes on its outer periphery and is snapped into the bottom of the fixed rod 52. Optionally, the foot 54 can be made of silicone, rubber, or engineering plastic.

[0026] In addition, the fixing rods 52 in this embodiment are not limited to three, but can also be four or more. However, in order to save costs and improve the stability of the tripod assembly 5, the fixing rods 52 in this embodiment are preferably three.

[0027] The fan assembly 2 includes an air duct 23, a blower 21, a motor 22, and a motor bracket 25. The air duct 23 is screwed into the housing 1. The motor bracket 25 is embedded in the inner cavity of the air duct 23 by mechanical locking or threaded fastening. The motor 22 is typically fixed to the motor bracket 25 by screws or clips. The bracket 53 and the motor 22 are shaped to match each other. Figure 2 As shown, the output shaft of the motor 22 is fixedly connected to the blower 21, and a rear cover 26 is fixedly connected to the side of the housing 1 near the blower 21. In this embodiment, the motor bracket 25 is also provided with a protective cover 24, and the air duct 23 is provided with an air duct cover 27 on the side near the rear cover 26. Optionally, the bracket 53 can be equipped with rubber pads or shock-absorbing rings to reduce the transmission of motor 22 vibration to other components.

[0028] The cleaning steps for the blower 21 in this embodiment are as follows: Remove the fixing screws of the rear cover 26, then hold the anti-slip textured part of the air duct cover 27, rotate it counterclockwise to remove it, and finally use a socket wrench to remove the nut of the blower 21 to take out the blower 21 for cleaning. The above design makes it easy for users to clean the dust accumulated on the blower 21, ensuring clean air output and preventing the air duct 23 from being blocked, which could cause motor overload.

[0029] A heating assembly 3 is disposed on one side of the fan assembly 2 and includes a heating element, an air duct 34, and a cooling fan 32. A front cover 35 is screwed to the side of the outer casing 1 near the heating assembly 3, and the heating element is fixed inside the front cover 35. The heating element includes a PTC heating element 31 and a PTC housing 33. The PTC heating element 31 is embedded inside the PTC housing 33, and the PTC housing 33 is screwed to the inside of the outer casing 1. An air duct 34 is fixed to the side of the PTC housing 33 away from the front cover 35, and the cooling fan 32 is fixed between the air duct 34 and the motor bracket 25. In this embodiment, the cooling fan 32 includes fan blades and a drive component.

[0030] When the weather is hot, users can turn off the PTC heating element 31 and use the cooling fan 32 and blower 21 to blow air and dissipate heat, increasing the fan volume and enhancing the airflow effect. When the weather is cold, users can turn on the PTC heating element 31 and use the cooling fan 32 to achieve a heating effect. By turning on the fan assembly at a low speed, it assists the PTC heating element 31 in dissipating heat, accelerates the circulation of hot air in the room, and thus achieves the purpose of rapid heating.

[0031] In addition, the circuit of this embodiment is also provided with a circuit protector 36, which includes a circuit breaker and a fuse.

[0032] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model.
