The impeller 3 includes a cylindrical mounting portion and a plurality of blades uniformly arranged on an outer peripheral surface of the mounting portion, and a second annular groove 31 fitted with the first annular boss 12 and a second annular boss 32 fitted with the first annular groove 13 are provided on an end surface of the mounting portion near the main body 1.
Specifically, the main body 1 is cylindrical, and the first annular boss 12 is annular. The first annular bosses 12 are integrally formed with the main body 1. The plurality of first annular bosses 12 are arranged at intervals of a collar, and the shaft hole 11 is arranged in line with the axial direction of the plurality of first annular bosses 12. It is easy to understand that in order to prevent the rotation of the output shaft 22 from being blocked by applying friction to the output shaft 22 due to the contact of the inner peripheral surface of the shaft hole 11 with the output shaft 22, the diameter of the shaft hole 11 is larger than that of the output shaft 22, and the shaft hole 11 is disposed so as not to contact with the output shaft 22. In the present embodiment, the number of the first annular bosses 12 is four, and in other embodiments, the number of the first annular bosses 12 may be set to two, three, or more.

In the present embodiment, the first annular boss 12 and the first annular groove 13 have rectangular cross-sectional shapes. In other embodiments, the cross-sectional shapes of the first annular boss 12 and the first annular groove 13 may be set to be triangular or trapezoidal, or the cross-sectional shape edges of the first annular boss 12 and/or the first annular groove 13 may be set to be arc-shaped.
Because the first annular boss 12 located at the outermost side surrounds the mounting portion of the impeller 3, as a preferred embodiment, the height of the first annular boss 12 can be set larger than that of other first annular bosses 12, so that the difficulty of external foreign matters entering the impeller 3 and the anti-winding protective sleeve can be effectively increased, and the depth of the second annular groove 31 on the mounting portion of the impeller 3 does not need to be increased.
It is easy to understand that the anti-winding protective sleeve may shake during use to rub against the impeller 3, so that the anti-winding protective sleeve is preferably made of self-lubricating and wear-resistant plastics, such as teflon, steel, nylon, and the like. It should be appreciated that other self-lubricating and wear resistant materials may be used to make the present anti-wind protective sleeve.
In summary, the anti-winding protective sleeve provided by the utility model can be sleeved outside the output shaft of the drainage pump, so that external foreign matters are prevented from approaching the output shaft of the drainage pump, and are prevented from winding on the output shaft and sliding down to the oil seal along the output shaft. The first annular boss and the first annular groove on the anti-winding protective sleeve can be embedded with the impeller, so that the difficulty that external foreign matters pass through the assembly gap between the impeller and the anti-winding protective sleeve and are close to the output shaft can be effectively increased, and the situation that the external foreign matters are blocked between the anti-winding protective sleeve and the impeller to cause the impeller to be blocked or even blocked is avoided.
