Abstract
The utility model relates to a dustproof structure of an external-rotor electronic fan, which has high dustproof effect. The dustproof structure of the external-rotor electronic fan comprises an external rotor fan. A stator aluminum bracket and a rotor bracket matching end surface in the external rotor fan in the external rotor fan are designed to an annular groove structure. An inner oblique surface of the end surface of the rotor bracket is inserted into the groove of the end surface of the stator aluminum bracket. A dustproof ring is fixed on the surface of a magnet; the dustproof ring and the rotor bracket form an annular groove; and furthermore the dustproof ring is matched with the inner ring wall of the groove of the stator aluminum bracket through insertion matching; after an O-shaped ring is placed between the stator aluminum bracket and the dustproof bracket, the O-shaped ring is fixed through screws; a rubber pad is arranged between the dustproof bracket and a lead wire waterproof cover and is fixed through screws; and the lead wire sheath and the lead wire waterproof cover are matched through interference fit. The dustproof structure of the external-rotor electronic fan has the following advantages: realizing high dustproof performance between the stator aluminum bracket and the end surface of a rotating end, realizing reliable dustproof performance between the stator aluminum bracket and the dustproof bracket, and realizing dustproof sealing between the lead wire sheath and the lead wire waterproof cover.
Description
Technical field
The utility model relates to a kind of dustproof construction with a kind of external rotor electronics blower fan of good dust-proof effect, belongs to the external rotor electric machine dustproof construction and makes field.
Background technique
CN102155422A, title " the low-noise outer rotor motor shaft flow fan of rain-proof dust-proof ", comprise casing (6), described casing (6) is fixed by three-support bar (7) and the stator end cap of external rotor electric machine (1), and the external rotor of described external rotor electric machine (1) matches with the wheel hub of impeller (2); Air intake one side at casing (6) is fixed with rainhat (3), in the inboard of rainhat (3), is provided with one deck silencing cotton (9).Its deficiency: the one, volume is large, affects using effect; The 2nd, dust-proof effect is not good.
Summary of the invention
Purpose of design: avoid the deficiency in background technique, design a kind of dustproof construction with a kind of external rotor electronics blower fan of good dust-proof effect.
Design proposal: in order to realize above-mentioned purpose of design.The utility model is on structural design, 1, the stator aluminum frame is designed to the matrix structure, pegging graft to coordinate with the rotor field spider end face forms the first protection, and dust ring is fixed on behind the magnetite surface in the stator aluminum frame ring boss and forms to peg graft to coordinate and form that second is dustproof to be protected; 2, after between stator aluminum frame and dust-proof frame boss face, placement O type circle is fixed by screw, form dustproof protection; 3, put between dust-proof frame and lead-in wire waterproof cover after rubber cushion and fix and form dustproof protection by screw; 4, lead wire sheath and lead-in wire waterproof cover form dustproof protection after adopting interference fit.
Technological scheme: a kind of dustproof construction of external rotor electronics blower fan, comprise outer rotor blower fan, stator aluminum frame in described outer rotor blower fan and rotor field spider coupling end face are designed to circular groove structure, the interior inclined-plane of rotor field spider end face inserts in the groove of stator aluminum frame end face, and dust ring is fixed on the magnetite surface and with rotor field spider looping groove and with stator aluminum frame groove internal ring wall, forms to peg graft and coordinates; Fix by screw after placing O type circle between stator aluminum frame and dust-proof frame; Be equipped with rubber cushion and by screw, fix between dust-proof frame and lead-in wire waterproof cover; Lead wire sheath and lead-in wire waterproof cover interference fit.
The utility model is compared with background technique, has both realized the stator aluminum frame and has turned good the preventing dust of holding between end face, has realized again the reliable dustproof while between stator aluminum frame and dust-proof frame, has realized the dust sealing between lead wire sheath and lead-in wire waterproof cover.
