Abstract

The invention discloses a fan blade-free lifting fan. The fan blade-free lifting fan comprises a cross-shaped base, wherein threaded holes are formed in the surface of the cross-shaped base, and boltsare connected in the threaded holes in a threaded mode; a supporting rod is fixedly connected to the lower surface of the cross-shaped base, the surface of the supporting rod is fixedly connected with a sleeve through a connecting rod, and the bottom end of the supporting rod is fixedly connected with a servo motor; the output shaft of the servo motor is fixedly connected with a rotating shaft, and the surface of the rotating shaft is sleeved with turbine fan blades; and the bottom part of the surface of the sleeve is fixedly connected with fan frames through through pipes, and a whole circleof ventilation grooves are formed in the inner walls of the fan frames. According to the fan blade-free lifting fan, the turbine fan blades, the through pipes, the fan frames and the ventilation grooves are arranged, so that the turbine fan blades rotate for stirring airflow, and the stirred airflow enter the ventilation grooves in the fan frames through the through pipes and is jetted out by theventilation grooves to form an air flow so that the effect that the fan blades of the lifting fan can also be used for supplying air can be achieved.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a bladeless ceiling fan. Background technique [0002] Ceiling fan is a kind of household electrical appliance commonly used in family life. It is generally installed on the ceiling. When the ceiling fan is working, it drives the fan blades to rotate, generating air flow and bringing a cool feeling to people; this kind of ceiling fan is generally installed on the In the room with a ceiling height of more than 2.8 meters, when the ceiling fan is installed in a room with a height of less than 2.8 meters, the fan blades will be too low. If you touch it, because the exposed fan blades are running at high speed, it will be harmful if people touch it. Contents of the invention [0003] The purpose of the present invention is to provide a bladeless ceiling fan, which has the advantage of built-in blades and solves the problem that the blades of ordinary ceilin...
