Abstract

The invention provides a novel fan with reinforcing ribs. The novel fan comprises a panel, an air-guiding cylinder, fan blades and a protection cover. A blade cavity is arranged on the panel and internally provided with the fan blades. The position, located on one side of the panel, of the fan blades is provided with the protection cover. The position, located on the other side of the panel, of the fan blades is provided with the air-guiding cylinder. The surfaces of the fan blades are provided with the protruding reinforcing ribs. The protection cover is formed by multiple annular steel strips connected via fixing parts. The fixing parts are arranged on the protection cover which is fixed onto the panel via the fixing parts. The technical scheme of the novel fan with reinforcing ribs is advantaged by being simple in structure, safe in application and high in air-breaking capability.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a novel fan with reinforcing ribs. Background technique [0002] A fan refers to an electric fan used to generate wind to keep cool in hot weather. It is a device driven by electricity to generate air flow. Classification by use can be divided into: household electric fans and industrial exhaust fans. Household electric fans: ceiling fans, desk fans, floor fans, wall fans, ceiling fans, ventilation fans, rotary fans, air conditioning fans (cooling fans), etc.; industrial exhaust fans are mainly used for forced air convection. Existing fan blades are smooth and arc-shaped, but the blades of this structure are not strong enough and are easily damaged during use, which affects the service life of the fan. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a new type of fan with reinforcing ribs, which ...
