Abstract

A shoe washing machine, including a housing, a washing tub provided in the housing, a pulsator, and a driving part. The shoe washing machine also includes a brush provided on the top center of the pulsator, and the brush is configured to be in a shape that projects upward from the top of the pulsator. When the pulsator rotates, the pulsator can drive the brush to rotate at the same time, so that bristles of the brush can move relative to shoes to rub and brush the shoes, so that by improving the linear smoothness of the brushing surface of the brush, an effect of brushing without damaging the shoes can be achieved, and the probability of the shoes getting stuck by the brush can be reduced.

First claim

What is claimed is:

1. A shoe washing machine, comprising:
a washing tub,
a pulsator rotatably arranged at an inner bottom portion of the washing tub, and
a brush arranged at a center of a top portion of the pulsator, wherein the brush is arranged in a shape that bulges upward from the top portion of the pulsator and is detachably connected with the pulsator,
wherein a bottom portion of the brush is provided with a snap-fit seat, and the snap-fit seat has a side wall provided with a plurality of snap-fit grooves in a circumferential direction;
wherein the side wall includes a side wall segment formed between every pair of adjacent snap-fit grooves in the circumferential direction, and the side wall segments have an elastically deforming ability,
wherein the side wall segments located at two opposite sides of each of the snap-fit grooves and close to an opening of the snap-fit groove are respectively provided with a convex structure in a direction of approaching each other; and
wherein the top portion of the pulsator is provided with snap-fit protrusions matching with the snap-fit grooves, and the snap-fit protrusion is provided with accommodation grooves matching with the convex structures so that the brush is able to be detached from the pulsator by slightly pushing a bottom of the side wall segment outward to move the convex structures from the accommodation grooves.

2. The shoe washing machine according to claim 1 , wherein the brush is arranged to have a radial size that gradually increases or stepwise increases from a top portion to a bottom portion.

3. The shoe washing machine according to claim 2 , wherein the brush is a bowl-shaped brush, a conical brush, a spherical brush or a dome-shaped brush.

4. The shoe washing machine according to claim 1 , wherein the brush comprises a lower section and an upper section; the lower section is arranged in a columnar shape, and the upper section is arranged in a shape that bulges upward from a top portion of the lower section.

5. The shoe washing machine according to claim 4 , wherein the upper section is bowl-shaped, conical, spherical or dome-shaped.

6. The shoe washing machine according to claim 1 , wherein a bottom portion of the brush is arranged to abut against the top portion of the pulsator.

7. The shoe washing machine according to claim 1 , wherein the snap-fit protrusions are water-stirring ribs of the pulsator, and a snap-fit column matching with the snap-fit seat by insertion is provided at a center intersection position of the water-stirring ribs.

8. The shoe washing machine according to claim 7 , wherein the snap-fit seat is gradually expanded outward from top to bottom.

9. The shoe washing machine according to claim 1 , wherein the bottom portion of the brush is provided with a threaded structure, and the pulsator is further provided with a fastener through hole aligned with the threaded structure.
