Abstract

The present invention discloses an anti-salt-fog DC fan with potting structures at two sides. The DC fan is formed by a shell, a rotor assembly, a circuit board, a lower end piece, a winding, a stator punching sheet group, a bearing and an upper end piece. The stator punching sheet group is pressed in the shell. The lower end piece, the upper end piece, the winding and the circuit board are fixed in the shell through the stator punching sheet group. Both the lower end piece and the upper end piece are respectively fixed to the upper end and lower end of the stator punching sheet group through the winding of the winding. The circuit board is fixed through a jaw on the lower end piece and the groove of the shell. The anti-salt-fog DC fan with potting structures at two sides belongs to a single-phase permanent magnet brushless DC fan, the structure is simple, with the use of electronic circuit commutation, the anti-salt-fog ability of the fan is improved, the stator assembly of the fan is subjected to double-sided potting, and thus the circuit board assembly and the winding are completely isolated from the air.

Description

technical field [0001] The invention relates to the technical field of structural design and application of a DC fan, and in particular provides a DC fan with a double-sided potting structure to prevent salt spray. Background technique [0002] The existing plastic shell is mainly used in supporting equipment of DC fans for civilian products, and has poor environmental resistance and cannot be used in harsh environments. People are eager to obtain a double-sided potting structure anti-salt spray with excellent technical effects DC fan. Contents of the invention [0003] The purpose of the present invention is to provide a double-sided potting structure anti-salt fog DC fan with excellent technical effect. [0004] The direct current blower with double-sided potting structure anti-salt spray is composed as follows: housing 1, rotor assembly 2, circuit board 3, lower end piece 4, winding 5, stator punching set 6, bearing 7 and upper end piece 8; stator punching The sheet g...
