Abstract

The invention discloses a combined fan device which comprises a fan unit and a driving unit. The fan unit comprises a first shell and an impeller located in the first shell, and an air inlet and an air outlet are formed in the first shell. The driving unit comprises a second shell, a motor and a driving shaft; the front end of the driving shaft extends out of the second shell to form a driving head, and the driving head penetrates into the first shell to be connected with the impeller. The motor drives the impeller to rotate through the driving shaft; a driving shaft of the driving unit drives an impeller in the fan unit to rotate, so that the fan unit has an air blowing effect; the fan unit is powered by the driving unit, so that electronic components such as a motor and a switch can be omitted, and the fan unit can be directly cleaned with water; a motor and the like are omitted in the fan unit, so that the overall manufacturing cost of the fan unit and the fan unit is reduced; meanwhile, the driving unit is inserted into the fan unit, the entertainment effect of an assembling tool is achieved, and the fan can be loved and welcomed by students or office workers.

Description

technical field [0001] The present invention relates to a fan, in particular to a combined fan device. Background technique [0002] The electric eraser is driven by a motor to rotate the eraser for erasing pencil words. [0003] Handheld fan, easy to be small and portable, can be used at home or when traveling in hot summer. It includes a handle and a fan body at one end of the handle. The fan body includes a casing and a fan blade in the casing, and a motor for driving the fan blade to rotate is usually arranged in the handle. [0004] The multi-purpose electric eraser with the publication number of CN2169555Y discloses that a micro-motor is arranged in the casing, a transmission wheel is arranged on the outlet shaft of the micro-motor, a passive wheel is arranged corresponding to the traditional wheel, and the eraser head is arranged on the passive wheel . [0005] There is no combination of the two in the market and related literature. SUMMARY OF THE INVENTION [0...
