Close, realize the transmission of the power of the internal bucket 100 of impeller external member 230.
Pass through the attachment structure between above-mentioned each part so that the drive shaft 310 is realized to impeller 210 and interior bucket 100
Synchronous driving, so, the interior bucket 100 by screw without that can be fixed on impeller 210 so that realize envelope in the bucket bottom of interior bucket
Structure is closed, the interior bucket fully can isolate with outer barrel so that the inside of interior bucket 100 is mutually isolated with impeller 210, it is to avoid connect
Sheltering evil people and countenance evil practices in structure, and the transmission of the rotational power of bucket 100 in 210 pairs of impeller is realized, effectively reduce the dirt on interior bucket 100
Dirt, and interior bucket 100 is easily installed and is dismantled.
In order that it is higher to the power transmission efficiency of impeller 210 to obtain the inserts 220, in one embodiment, such as Fig. 3 institutes
Show, the inserts 220 is arranged in the through hole 213, for example, the through hole 213 has the polymorphic structure phase with the inserts 220
The odd-shaped cross section of matching, specifically, in each embodiment, matches to be identical, or, match and combine or match somebody with somebody for mutually correspondence
Close.For example, the odd-shaped cross section includes square-section, for example, the odd-shaped cross section includes polygonal cross-section, for example, the odd-shaped cross section
Including irregular polygon section, it is worth mentioning, because the inserts 220 and through hole 213 are respectively provided with odd-shaped cross section, inserts 220
The hole wall of outer surface and the through hole 213 be brought into close contact so that both do not allow to be also easy to produce rotation between the two when rotating
Circumferencial direction top offset, and then make it that power transmission efficiency between inserts 220 and impeller 210 is higher, and increase both it
Between interaction force area, and then reduce the stress of screw.
In order that the connection for obtaining the inserts 220 and impeller 210 and impeller external member 230 is more firm, in one embodiment
In, with reference to Fig. 2, Fig. 3 and Fig. 4, the inserts 220 includes connecting portion 222 and the abnormity portion 223, the connecting portion of integrally connected
222 are connected to the impeller 210, and the connecting portion 222 is provided with some first screws 224 and some second screws 225, institute
State inserts 220 to be spirally connected with the impeller 210 by first screw 224, the inserts 220 passes through second screw 225
It is spirally connected with the impeller external member 230, the special-shaped portion 223 has odd-shaped cross section, and the special-shaped portion 223 is arranged in the through hole
In 213, the special-shaped slot 231 is sheathed on the outside in the special-shaped portion 223.
For example, incorporated by reference to Fig. 1 and Fig. 3, the special-shaped portion 223 is the column with odd-shaped cross section, for example, connecting hole 221 is passed through
The connecting portion 222 and the special-shaped portion 223 are worn, for example, the connecting portion 222 has the first face and second being disposed opposite to each other
Face, the special-shaped portion 223 is connected to first face, for example, the special-shaped portion 223 is by the dorsad impeller external member 230 of impeller 210
Simultaneously pass through the through hole 213, and the first face of the connecting portion 222 is connected to the one side of the dorsad impeller external member 230 of impeller 210,

For example, refer to Fig. 8, second spline 121 include some 3rd key portions 122 for being matched with the first key portion 234 with
And some 4th key portions 123 matched with second keyed 236, width and the 4th key portion 123 in the 3rd key portion 122
Width is different to be set, for example, the 3rd key portion 122 is engaged with the first key portion 234, the 4th key portion 123 and described second
Key portion 236 is engaged, for example, rat of the first key portion 234 along the impeller external member 230 is set, the second keyed
236 thickness is less than the thickness in the first key portion 234, for example, table of the second keyed 236 along the impeller external member 230
Face depression is set, for example, inner surface depression of the 3rd key portion 122 along the interior casing part 120 is set, for example, described
Inner surface projection of the 4th key portion 123 along the interior casing part 120 is set, and passes through above-mentioned impeller external member 230 and interior casing part
120 depression and raised cooperation, realize the engagement of the first spline 232 and the second spline 121.
Because the first spline 232 has the first key portion 234 and second keyed 236 that width is different and shape is different, with
And second spline 121 have the 3rd key portion 122 and the 4th key portion 123, on the one hand, so that casing part 120 in 230 pairs of impeller external member
Transmission efficiency it is higher, on the other hand the interior casing part 120 of the interior bucket 100 is quickly set in impeller external member 230,
And the goodness of fit in causing between casing part 120 and impeller external member 230 is higher so that connection between the two is more close, makes
Bucket 100 can be firmly secured on impeller 210 without screw in obtaining.In installing during bucket 100, it is only necessary to by interior casing part 120
On the second spline 121 alignd with the first spline 232 of impeller external member 230, you can so that bucket bottom 111 fits in impeller completely
210 shape so that the installation of interior bucket 100 is more efficient and convenient, and then effectively increase peace of the interior bucket 100 on impeller 210
Fill efficiency.
In order that obtaining the interior casing part 120 can quickly be enclosed in impeller external member 230, for example, referring again to Fig. 8, often
Second keyed 236 described in one is set between two adjacent the first key portions 234, for example, the first key portion 234 and described
Second keyed 236 is arranged at intervals successively, and the center of circle of the circular cross-section around the impeller external member 230 is set, for example, each described the
One key portion 234 is placed equidistant, for example, each second keyed 236 is placed equidistant, so, on the one hand causes the interior casing part 120
More uniformly spread with the Interaction Force of impeller external member 230, on the other hand, be conducive to interior casing part 120 to be quickly enclosed on ripple
Take turns in external member 230, and then effectively improve the installation effectiveness of interior bucket 100.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope of this specification record is all considered to be.
Embodiment described above only expresses several embodiments of the present utility model, and it describes more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that for the common skill of this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
Protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
