It is provided in this embodiment to have except above-mentioned bearing 152 is in bearing holder (housing, cover) 151 in addition to the setting difference of limit method
The integrated motor other structures setting principle of impeller 21 is identical with embodiment one, and this will not be detailed here.
Embodiment three：
As shown in Figure 15 and Figure 16, the integrated motor provided in this embodiment with impeller 21, with embodiment one, implementation
The main distinction of example two is that the set-up mode of 11210 madial wall of 151 lateral wall of bearing holder (housing, cover) and/or hollow endoporus is different, specifically
Ground, in the present embodiment, be additionally provided with the lateral wall of bearing holder (housing, cover) 151 several circumferentially spaced settings for glue accumulate first
Groove 1512, the madial wall of hollow endoporus 11210 are additionally provided with the second ditch that several circumferentially spaced settings are accumulated for glue
Groove 11211.The setting of first groove 1512 and second groove 11211, beneficial to the product between bearing holder (housing, cover) 151 and rack body 1121
More glue is deposited, so that beneficial to the lasting bonding force of glue between enhancing bearing holder (housing, cover) 151 and rack body 1121, and then greatly
Improve to degree the solid and reliable property that bearing holder (housing, cover) 151 is installed in rack body 1121.Herein, while in bearing holder (housing, cover) 151
First groove 1512 is set on lateral wall and second groove 11211 is set in the madial wall of hollow endoporus 11210；Of course, have
In body application, first groove 1512 also can be only set on the lateral wall of bearing holder (housing, cover) 151, alternatively, only in hollow endoporus 11210
Madial wall sets second groove 11211.
In addition to the set-up mode difference of 11210 madial wall of above-mentioned 151 lateral wall of bearing holder (housing, cover) and/or hollow endoporus, this
The integrated motor other structures setting principle with impeller 21 that embodiment provides is identical with embodiment one or embodiment two
(limit method of the present embodiment middle (center) bearing 152 in bearing holder (housing, cover) 151 can use the set-up mode in embodiment one, can also use
Set-up mode in embodiment two), this will not be detailed here.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modification, equivalent substitution or improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
