Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 6, the detachable pulsator device of the present invention includes a pulsator shaft 10 and a pulsator 20.

The peripheral wall of the impeller shaft 10 is provided with a spline 12 and a clamping groove 11, the impeller shaft 10 is connected with a driving device 30, and the driving device 30 is used for driving the impeller shaft 10 to rotate.

The impeller 20 install in the washtub 40, can wash the clothing when the impeller 20 rotates, the impeller 20 on be provided with a shaft hole 21, at least one joint spare 22 and at least one retaining member 23, joint spare 22 and retaining member 23 one-to-one set up, impeller shaft 10 detachable pegs graft in shaft hole 21, retaining member 23 is used for applying force to joint spare 22 so that joint spare 22 chucking is in the draw-in groove 11, like this, make joint spare 22 chucking in the draw-in groove 11 of impeller shaft 10 through retaining member 23, thereby make impeller 20 and impeller shaft 10 firm in connection, can avoid impeller 20 at high-speed rotation in-process axial float on impeller shaft 10.

The draw-in groove 11 be ring groove, ring groove sets up around the axis of impeller shaft 10, joint spare 22 and retaining member 23 all have two, install back on impeller shaft 10 when impeller 20, two joint spare 22 are located the both sides of impeller shaft 10 respectively, two retaining members 23 are used for making the equal chucking of two joint spare 22 in draw-in groove 11 to two joint spare 22 application of force respectively, two joint spare 22 relative direction sets up, like this, two joint spare 22 press from both sides tight fixed with impeller shaft 10 to it is more firm to make to be connected between impeller 20 and the impeller shaft 10.
