As shown in fig. 3, in yet another possible embodiment, the shape of the brush 5 rising upward from the top of the pulsator 3 is specifically the shape of the brush 5 rising directly upward from the top of the pulsator 3, in which case the body 51 rises directly upward with the bottom as a starting point, and the radial dimension of the body 51 becomes gradually larger from the top to the bottom. The body 51 of the brush 5 shown in fig. 3 includes three brush segments, the radial dimension of each brush segment is gradually increased from top to bottom, but the radial dimension of the connecting position of the three brush segments is not uniformly changed, and there is a position where the radial dimension is suddenly changed at the connecting position of the brush segments, but the three brush segments have a tendency of rising upward from the top to the bottom as a whole. Of course, in addition to the brush segments having the arc-shaped side portions shown in fig. 3, in the case where the brush 5 has a gradually larger radial dimension from the top to the bottom, at least one of the brush segments included therein may be a cylindrical brush segment having a fixed radial dimension, in which case the brush 5 includes a plurality of cylindrical brush segments, and the radial dimensions of the cylindrical brush segments increase sequentially from the top to the bottom.

Referring to fig. 4 and 5 with continued reference to fig. 1, fig. 4 is a front view illustrating a dome-shaped brush of the shoe washing machine of the present invention, and fig. 5 is a bottom view illustrating the dome-shaped brush of the shoe washing machine of the present invention. As shown in fig. 1, 4 and 5, in a preferred embodiment, the shape of the brush 5 rising upward from the top of the pulsator 3 is specifically the shape of the brush 5 rising directly upward from the top of the pulsator 3, in which case the body 51 rises directly upward with the bottom as a starting point, the radial dimension of the body 51 becomes gradually larger from the top to the bottom, and the body 51 as a whole expands and extends in a gradual manner from top to bottom. As an example, the brush 5 may be a bowl-shaped brush with a flat top and a side portion enclosing an arc-shaped surface protruding outward, or may be a tapered brush with a pointed top and a straight side portion, or may be a truncated cone-shaped brush with a flat top and a straight side portion, or may be an upward-protruding dome-shaped brush, as shown in fig. 4, the upward-protruding dome-shaped brush is the one shown in fig. 4, and as shown in the orientation of fig. 4, the body 51 of the dome-shaped brush is a rotating body obtained by rotating a section of an upward-protruding arc segment and a straight line segment extending from the bottom end of the arc segment to a direction close to the vertical rotating shaft along the vertical rotating shaft. The curved surface part of the rotating body and the joint position between the curved surface part and the horizontal plane at the bottom are fully distributed with the brush hair 52 to form a dome-shaped brush, and the tail ends of the brush hair 52 form a dome-shaped brush face. Wherein, the curvature of the curved surface of the dome-shaped brush and the radial size of the horizontal plane at the bottom can be set according to the washing requirements.

It will be appreciated by those skilled in the art that, although the brush 5 of the above embodiment is described in connection with the preferred case of progressively larger radial dimensions from top to bottom, however, the shape of the brush 5 is not limited to this case, for example, the brush 5 of the present invention may be configured such that a portion of the radial dimension becomes larger gradually and another portion of the radial dimension becomes smaller gradually from the position of the maximum radial dimension in the direction from the top to the bottom, as long as the height of the portion where the radial dimension becomes smaller is almost negligible as the most portion of the radial dimension of the body 51 of the brush 5 becomes larger gradually from the top to the bottom, if the shape of the body 51 is a three-quarter sphere, the height of the part of the body 51 with the smaller radial dimension does not negatively affect the soft and efficient brushing effect of the brush 5 and the effect of reducing the clamping frequency of the shoes.

Preferably, the bottom of the brush 5 is attached to the center of the top of the impeller 3, so as to prevent the brush 5 and the impeller 3 from having a significant gap and causing shoes to be clamped between the brush 5 and the impeller 3.

With continued reference to fig. 1, 4 and 5, in a specific embodiment, the horizontal plane at the bottom of the dome-shaped brush is disposed to be flush with the highest position at the top center of the pulsator 3, so as to prevent a gap with a large radial depth and a large vertical height from being formed between the bottom of the dome-shaped brush and the pulsator 3, and prevent shoes from being stuck between the bottom of the dome-shaped brush and the pulsator 3 when being shifted by the pulsator 3 or the brush 5. Specifically, when the top of the pulsator 3 is provided with a plurality of water-repellent ribs 31 along the radial direction and the plurality of water-repellent ribs 31 intersect at the top center position of the pulsator 3, the horizontal plane at the bottom of the dome-shaped brush is attached to the top side of the water-repellent ribs 31 at the center position of the pulsator 3.

Referring to fig. 6 and 7, fig. 6 is a schematic view illustrating a forward structure of a bowl-shaped brush of the shoe washing machine of the present invention, and fig. 7 is a schematic view illustrating an installation of the bowl-shaped brush of the shoe washing machine of the present invention. As shown in fig. 6 and 7, in another preferred embodiment, the brush 5 is a bowl-shaped brush, the top of the body 51 of the bowl-shaped brush is flat and approximately planar, the side part is enclosed by an arc-shaped curved surface which protrudes outwards and has a gradually increased radial dimension, the bottom edge of the bowl-shaped brush is directly attached to the top center of the impeller 3, the intersection positions of a plurality of water stirring ribs 31 at the top center of the impeller 3 are directly buckled inside the bowl-shaped brush 5, no gap exists between the brush 5 and the water stirring ribs 31 and the top surface of the impeller 3, and shoes are prevented from being clamped at the bottom of the brush 5.

In another preferred embodiment, the brush 5 is a spherical brush, the bottom of the lower hemisphere of the spherical brush is a curved surface gathered at the bottom center, and the bottom of the spherical brush is embedded and attached to the top center of the pulsator 3, so that the width of the gap between the bottom of the lower hemisphere of the spherical brush and the pulsator 3 is very small (almost nonexistent), and shoes are not substantially clamped between the bottom of the spherical brush and the pulsator 3.

Preferably, the height of the middle part of the spherical brush, the bowl-shaped brush or the dome-shaped brush or the brush with gradually increased radial size from the top to the bottom is not more than 15 cm. Wherein, the "middle height specifically means: the vertical distance between the highest position of the top of the bulge shape of the brush 5 and the center position of the top of the pulsator 3 (the distance that the brush 5 extends into the body of the pulsator 3 when connected is not counted in the height). Can prevent 5 focus height of brush through the aforesaid setting from being too high, guaranteed the installation stability of brush 5 for 5 can not rock when rubbing shoes of brush, brush 5 is high to the tolerance of shoes collision.

The preferred connection between the brush 5 and the impeller 3 will be described with continued reference to the accompanying drawings and the bowl-shaped and dome-shaped brushes:

preferably, the brush 5 is detachably connected to the pulsator 3 so that the brush 5 mounted and fixed can be detached when there is a problem in that the brush 5 is worn by the bristles 52, etc. Wherein, a person skilled in the art can selectively set a mounting base at the bottom of the body 51 according to the specific shape of the body 51 of the brush 5 and the specific shape of the top of the pulsator 3.

Still referring to fig. 4 and 5, in a specific embodiment, a cylindrical clamping seat 53 (i.e. the above-mentioned mounting base) is disposed at the center of the bottom horizontal plane of the dome-shaped brush, the cylindrical clamping seat 53 is disposed vertically with the cylinder opening facing downward, a plurality of clamping grooves 54 are disposed on the sidewall of the cylindrical clamping seat 53 along the circumferential direction, and a clamping protrusion matched with the clamping groove 54 is disposed on the top of the pulsator 3, so that the dome-shaped brush 5 can be connected with the raised clamping fit through the clamping groove 54. In the mounted state, the bottom side of the cylindrical holder 53 is closely attached to the top surface of the center of the pulsator 3.

Further, the dome-shaped brush is mounted to the pulsator 3 mainly by a snap-fit manner. For example, the side wall of the cylindrical clamping seat 53 located between the clamping grooves 54 has a certain elastic deformation capability, two side groove walls of the clamping grooves 54 close to the notch are respectively provided with a protruding structure along the direction close to each other, and the clamping protrusion is provided with a receiving groove matched with the two protruding structures. When the dome-shaped brush is mounted, the catch 54 is captured on the catch projection and the projection slides along the surface of the catch projection and then enters and is captured in the receiving groove. When the dome-shaped hairbrush needs to be detached, the protruding structure can be moved out of the accommodating groove only by slightly snapping the bottom of the side wall of the cylindrical structure outwards, so that the dome-shaped hairbrush is detached.

Further, the dome-shaped brush is additionally mounted to the pulsator 3 in a screw manner. Specifically, in addition to the cylindrical holder 53 and the locking groove 54, a thread structure 55 is provided at the bottom center of the dome-shaped brush 5, and a fastener through hole aligned with the thread structure 55 is provided through the top center of the pulsator 3.

In addition, the central intersection position of the water stirring rib 31 is convexly provided with a clamping column which is in splicing fit with the cylindrical clamping seat 53, so that the installation reliability of the dome-shaped brush is further improved, and the anti-collision performance of the dome-shaped brush is improved. Under the condition of good clamping, the cylindrical clamping seat 53 is clamped on the clamping column, and the clamping groove 54 is clamped on the water-repellent rib 31 of the impeller 3, so that the bottom of the dome-shaped brush body (namely the body 51) is tightly attached to the top surface of one side of the water-repellent rib 31 close to the center of the impeller 3.

Further, the cylindrical clamping seat 53 is gradually expanded from top to bottom, the radial dimension is gradually increased, and the clamping column at the top of the impeller 3 is set to be a circular truncated cone-shaped column matched with the cylindrical clamping seat 53, so that the clamping contact area between the circular-arc-shaped brush and the impeller 3 is further increased, and the reliable installation effect of the circular-arc-shaped brush is further improved.

Alternatively, the vertical height of the cylindrical clamping seat 53 arranged at the bottom of the dome-shaped brush is not greater than the height of the clamping column arranged at the top of the impeller 3, so that the bottom end of the cylindrical clamping column is positioned above the water stirring rib 31 when the cylindrical clamping seat 53 is clamped on the clamping column. At this time, the cylindrical card seat 53 is not provided with the card slot 54, but is provided with a plurality of bolts at the top of the inner side thereof, the top of the card column is provided with a jack matched with the bolts, and the threaded hole is arranged at the center of the plurality of bolts and surrounded by the plurality of bolts. In the state that the dome-shaped brush is mounted, the cylindrical holder 53 is caught on the catching column to restrict the horizontal movement of the dome-shaped brush, the catching pin is inserted into the insertion hole to restrict the rotation of the dome-shaped brush, and the fastening member restricts the axial movement of the dome-shaped brush. Wherein, the arrangement positions of the bolt and the jack can be interchanged.
