Abstract

The invention discloses a small fan with a novel waterproof and dustproof structure and a brushless motor with an outer rotor. The small fan comprises fan blades, wherein a shaft core is arranged in the fan blades; a motor shell is arranged inside the fan blades, and a magnetic strip is arranged inside the motor shell; a front ball bearing is connected to the shaft core in a sleeving manner, and the magnetic strip is connected to the inside of an outer frame in a sleeving manner; a snap ring and a gasket are connected to the shaft core in a sleeving manner, and a rear ball bearing and the front ball bearing are arranged on the shaft core; a copper middle pipe is connected to the rear ball bearing and the front ball bearing in a sleeving manner; and a cylindrical spring is connected to theshaft core in a sleeving manner. The designed fan with the novel waterproof and dustproof fan structure has excellent waterproof effect, can be used in wet places for a long time, can also be used ina water spraying environment, can further be wholly placed into water when used without affecting properties, also has excellent dustproof effect, and can meet IP68 standard requirements.

Description

technical field [0001] The invention relates to the technical field of cooling fans, in particular to a small fan with a novel waterproof and dustproof structure and an outer rotor brushless motor. Background technique [0002] In the existing waterproof and dustproof design of domestic cooling fans, two methods are mainly used for waterproof and dustproof treatment. The first is to use a thinner protective layer to protect the stator and isolate water and dust, such as vacuum coating , dipping varnish process, etc.; the second is to use a thicker curing glue to wrap the stator to isolate the stator from water and dust, such as potting glue process, low-temperature injection molding process, etc., but the new waterproof and waterproof in the prior art The small fan with dust structure and the brushless motor with outer rotor also have the following deficiencies. [0003] The first type of protective layer is relatively thin, for example, the thickness of the vacuum coating ...
