As optimization, the external diameter of described annular sidewall is more than the diameter of described stepped hole, and can be inserted to described step
In the hole.
So so that forming sealing between annular sidewall and the hole wall of stepped hole, raising acoustic filter is conducive to be tightly connected
Structurally overall sealing.
As optimization, the outside of described annular sidewall is in truncated cone-shaped towards one end of described electromotor, and the diameter of end
Diameter less than described stepped hole.
So, by the truncated cone-shaped structure of annular sidewall end, more easily annular sidewall can be inserted stepped hole
Interior, be conducive to improving efficiency of assembling.
As optimization, the inner side of described annular sidewall has the internal coiling lobe in female thread shape, described acoustic filter
The outer surface of installation end has the external spiral lobe that can match, the interior spiral shell of described sealing gasket with described internal coiling lobe
Rotation lobe is closely screwed in the external spiral lobe of described acoustic filter.
Using said structure, sealing gasket is closely joined together with acoustic filter by the way of screw thread-like cooperation, has
Beneficial to the sealing improving therebetween, improve soundproof effect.
In sum, this utility model has structure simply, easy for installation, is conducive to improving efficiency of assembling, strengthens sealing
Performance, improves soundproof effect；Effect of heat insulation preferably, is conducive to service life of raising ternary catalyzing unit and oxygen sensor etc. excellent
Point.
