[0002] With the increasing popularity of wireless charging for mobile phones, the demand for wireless chargers is becoming more and more widespread, especially in cars. Wireless charging is a way of charging through wireless power transmission. It converts electrical energy into other forms of relay energy (such as electromagnetic field energy, laser, microwave and mechanical waves, etc.) through a transmitter, transmits it over a certain distance, and then converts the relay energy into electrical energy through a receiver, and then transmits the electrical energy to the battery to achieve wireless charging. The wireless charger is equipped with a transmitter, and the device to be charged is equipped with a receiver. Wireless charging can be achieved for the device to be charged through the wireless charger. In order to dissipate heat, the wireless charger is generally also equipped with a fan assembly to dissipate heat for the device to be charged.

When the device to be charged needs to be charged, the user places the device to be charged on the top of the wireless charger, and the device to be charged will block the air outlet. The gas enters the fan assembly from the air inlet, flows through the fan blades, and then blows toward the device to be charged from the air outlet, dissipating heat and cooling the device to be charged. However, when the device to be charged does not need to be charged and leaves the wireless charger, the air outlet is not blocked by the device to be charged, and tiny foreign objects from the outside will fall into the air outlet and thus enter the inside of the fan assembly. When the fan assembly is running, the foreign objects in the fan assembly will be drawn into the fan blades, thereby affecting the normal operation of the fan assembly and causing abnormal noise.

[0027] Wireless charging is a way of charging through wireless power transmission. It converts electrical energy into other forms of relay energy (such as electromagnetic field energy, laser, microwave and mechanical wave, etc.) through a transmitter, transmits it over a certain distance, and then converts the relay energy into electrical energy through a receiver, and then transmits the electrical energy to the battery to achieve wireless charging. The wireless charger is equipped with a transmitter, and the device to be charged is equipped with a receiver. The wireless charger can realize wireless charging of the device to be charged.
