Casing on body is divided into left shell, central enclosure, right shell, and the upper end of left shell and the upper end of right shell are all higher than
Central enclosure upper end, and protective cover is arranged between left shell and right shell, the overall structure of the present invention can be made more
It is compact, it can avoid because setting protective cover to cause vavuum pump integrally excessive, the hook-shaped fastener in protective cover lower end can be right from central enclosure
Hook-shaped neck is slipped into side, when hook-shaped fastener is embedded in hook-shaped neck, the right flank of left shell and the left side of right shell
Face is respectively held against the left and right sides of protective cover, is so quite convenient to the installing/dismounting of protective cover, and overall structure is more
It is compact, be conducive to saving space.In order to save space, so protective cover inner space is limited, and the hook of protective cover lower end both sides
Shape fastener is to bending on the inside of protective cover, so the remaining width in the position that protective cover can be caused to be located between two hook-shaped fasteners is too small,
And be used to be integrated with more electric elements on the drive circuit board of driving stream brushless electric machine, this may result in drive circuit board
Must have these integrated electric elements of enough areas, thus can cause the remaining short of width in position between two hook-shaped fasteners with
Drive circuit board is installed, and the drive circuit board of the present invention is installed on the supporting plate by support column, support column is by drive circuit
Plate is lifted, and drive circuit board is avoided hook and is arranged on higher place, so that can have enough width in protective cover
For installing drive circuit board.
