Description

Air supply device and electronic equipment Technical Field The present application relates to the field of electronic device heat dissipation technologies, and in particular, to an air supply device and an electronic device. Background The electric fan is used as an electric device for driving the fan blades to rotate by utilizing a motor so as to circulate air, and is mainly applied to heat dissipation and ventilation. In electronic devices, such as notebook computers, an electric fan is used as a main heat dissipation element, and is intended to cool down devices inside the electronic device, so as to ensure normal operation and prolong the service life of the electronic device. However, most fans today have fixed blades and cannot be adjusted in angle, which limits their application in certain situations. For example, in some environments with more dust, dust and dirt are easily accumulated on the fan blades, which not only affects the working efficiency of the electric fan, but also may cause poor heat dissipation, thereby affecting the performance of the electronic device. Because the fan blade can not adjust the angle, the user can not clean the fan blade through a simple mode, and can only rely on manual cleaning. This not only increases the difficulty and effort of maintenance, but may also affect the use experience of the device.
