Abstract:
A desktop fan is provided. The desktop fan comprises a base (1), a U-shaped support (2), a housing (3), blades (4), and a battery mounting bracket (5). A bottom end of the U-shaped support (2) is fitted on and rotatably connected to a top surface of the base (1). A lower half of the housing (3) fits within and connects to a U-shaped groove of the U-shaped support (2). Two sides of the housing (3) are hinge-connected to inner side surfaces of two side rods of the U-shaped support (2). The battery mounting bracket (5) is fixedly mounted on a back surface of the housing (3). A back surface of the battery mounting bracket (5) is provided with a battery mounting slot (51). A shaft of the blades (4) is fitted into and connected to the battery mounting bracket (5) by means of a PWM control system. The blades (4) are fitted and mounted in the housing (3). The fan can be powered by a battery, and can use the PWM control system to enable the blades to maintain a substantially constant rotational speed at different input voltages.
