以下结合附图对本发明的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
如图1－图3所示，本发明提供一种滚筒海绵实施例。
该滚筒海绵包括滚筒本体和安装于滚筒本体B2圆周表面的滚筒海绵B1，所述滚筒海绵B1表面沿滚筒本体B2径向方设有凹槽B11，所述滚筒海绵B1厚度的为滚筒海绵外径与内径之差的一半。
具本地说，所述滚筒海绵B1的外径为分度圆直径加上齿顶高系数*模数之积，其中模数为齿间距与齿数之比，分度圆直径为M与齿数之积。
所述滚筒海绵B1的内径为分度圆直径和齿底间隙系数与模数之积的差，其中齿底间隙系数为0.75-1，内类齿轮型内部的齿轮啮合的时候，为了在啮合齿廓之间形成运动膜，避免因轮齿摩擦发热膨胀而卡死，齿底之间必须留有间隙，此间隙称为齿底间隙。
所述滚筒海绵B1的内径为齿间距*齿数/Π-RX1*齿间距/齿数，其中Π表示齿数，RX表示R半径对齿底间隙系数，其中R 为齿底部半径 。所述滚筒海绵的外径为齿间距*齿数/Π-RX2*齿间距/齿数，其中Π表示齿数，RX2表示R半径对齿底间隙系数 ，X2为齿顶的系数，其中R 为齿底部半径。所述齿数量为 40.4 - 11.66 *R角半径- 0.05 *滚筒内径+ 0.68 *滚筒外径。
由于所述滚筒海绵B1厚度的为滚筒海绵B1外径R1与内径R2之差的一半，其很好兼容了清洁时形变时摩擦力与余留水分时滚筒海绵增加的摩擦阻力导致的功率和阻力增大。
所述滚筒海绵包括滚筒本体B2，该滚筒本体B2由筒状塑胶管或金属管B21，该滚筒本体B2一端设有驱动滚筒海绵转动的驱动电机(附图未标示)，另一端设有与驱动电机转轴在轴向上活动连接的滚筒轴芯B3，该滚筒轴芯B3上设有轴芯盖(附图未标示)和设于滚筒轴芯B3与滚筒本体B2之间的轴承(附图未标示),以及固定轴承的卡簧(附图未标示)和保护轴承(附图未标示)和卡簧的固定盖(附图未标示)。所述滚筒轴芯B3一端套有弹簧(附图未标示),可以保证在滚筒轴芯B3在轴向有一定活动余量，从而便于安装的拆卸。所述滚筒轴芯B3一端设有传动槽(附图未标示)，该传动槽与驱动电机转轴配合实现在长度方向上可伸缩，而且能传递转动力矩。所述滚筒轴芯B3还设有对其伸缩长度进行限制的限位结构(附图未标示),该限位结构可以采用与滚筒轴芯B3一体或分体的限位环。
所述凹槽B11沿滚筒海绵B1表面长度方向均匀分布,其数量根据需进行设置，如设若干个。由于所述凹槽B11两个侧面可以设置为垂直或近似垂直，这样可以在滚筒海绵B1表面B12与侧面B111之交接面形成清理刮刀B13。由于滚筒海绵B1在成型时与模具接触面形成比较密实结构，这样在清理时，该清理刮刀B13与清洁面上的顽固垃圾形成很好的切割作用，当滚筒海绵B1向F方向转动时，该清理刮刀B13能与清洁面之前形成刮割作用，从实能将顽固垃圾清理，即使不能清理，也可以将较大的顽固垃圾进行切割方式进行清理，从而提高清理顽固垃圾效果。
同时由于该凹槽B11内部有空腔，可以将清洁面上的液体刮走，在较大速度转动时该凹槽B11也能将带动清洗区域，能适应清洁面液体较多时清洁场景。此外，可以将颗粒状固体通过凹槽B11进行收集，避免有颗粒状和粉状垃圾等混合场所时，由于颗粒状垃圾存在使得滚筒海绵表面无法与清洁面接触或接触面较小，从而无法一次性将颗粒状和其他粉状垃圾一起清理，从而提高清洁效率。
根据需要，所述凹槽B11可以设置为截面呈梯字形或一个侧为斜面结构，这样可以改善清理刮刀B13清理效果，同时在清洁过程中也能具有更好搬运液体或颗粒状固体能力。所述凹槽B11的深度为1-2mm，该凹槽B11的宽度大于0.5mm。而且在两邻的凹槽B11之间宽度大于0.5mm，通过试验这样设置具有更好清洁效果，兼顾清洁效率和滚筒海绵B1的使用寿命面。而将两邻的凹槽B11之间距离与凹槽B11的宽度相同，同样也具有较好清理效果和耐磨性。
根据需要，所述凹槽B11面积占滚筒海绵圆周表面1/4-1/2。所述凹槽沿滚筒海绵长度方向呈螺旋、弧形或条形，其中螺旋、弧形通过试验螺旋、弧形具有更好的效果。所述凹槽B11至少一个侧面为斜面，该斜面与滚筒海绵表面形成小于90度的夹角。
根据需要，为了保证所述滚筒海绵具有适当的摩擦力和清洁效率，在该滚筒海绵表面分布有露出滚筒海绵内层的内层区域（附图未标示），该内层区域间隔分布。
所述滚筒海绵表面设置的凹槽B11及凹槽B11之间平滑连接，这样也可以实现清洁效果，通过试验比较，该实施例的效果稍差于上述实施例。
如图4所示，所述凹槽B11沿滚筒海绵表面沿轴向呈V字形结构，这样可以清洁时，可以使凹槽B11的清理刮刀B13在与清洁面接触时只能局部接触，可以避免在与清洁面同一位置接触时与清理刮刀B13有较大的接触面，从而增加接触阻力。同时由于该凹槽B11在滚筒海绵表面呈V字形分布，使得凹槽B11上形成的清理刮刀B13在清理污渍时从污渍侧面渐进式进行切割，既能提高清理效果，又可以减少清理时的阻力。根据需要，沿滚筒海绵轴向垂直正投影时凹槽B11为斜面或弧形结构。
为了进一步提高清洁固体污渍效果，所述清理刮刀B13分布的多个豁口B4,如图5所示,这样在斜面结构的清理刮刀B13转动时在豁口 B4作用下形成锯齿运动，从而更好清理固体污渍。
根据需要，所述滚筒本体B2与滚筒海绵B2之间交接面设有使两者结合更紧固的螺旋结构，且该螺旋方向在滚筒海绵工作时转动方向相反。该螺旋结构包括如螺纹相同或类似结构，在滚筒海绵时，滚筒本体B2与滚筒海绵B2之间向紧固方向动运趋势。
本发明提供一种滚筒海绵制造方法实施例。
该滚筒海绵制造方法包括在滚筒本体B2表面形成滚筒海绵B2得到滚筒海绵，在该滚筒海绵B2表面形成厚度的为滚筒海绵外径与内径之差的一半所述滚筒海绵B1表面沿滚筒本体B2径向方设有凹槽B11，所述滚筒海绵B1厚度的为滚筒海绵外径与内径之差的一半。
具本地说，所述滚筒海绵B1的外径为分度圆直径加上齿顶高系数*模数之积，其中模数为齿间距与齿数之比，分度圆直径为M与齿数之积。
所述滚筒海绵B1的内径为分度圆直径和齿底间隙系数与模数之积的差，其中齿底间隙系数为0.75-1，内类齿轮型内部的齿轮啮合的时候，为了在啮合齿廓之间形成运动膜，避免因轮齿摩擦发热膨胀而卡死，齿底之间必须留有间隙，此间隙称为齿底间隙。
所述滚筒海绵B1的内径为齿间距*齿数/Π-RX1*齿间距/齿数，其中Π表示齿数，RX表示R半径对齿底间隙系数，其中R 为齿底部半径 。所述滚筒海绵的外径为齿间距*齿数/Π-RX2*齿间距/齿数，其中Π表示齿数，RX2表示R半径对齿底间隙系数 ，X2为齿顶的系数，其中R 为齿底部半径。所述齿数量为 40.4 - 11.66 *R角半径- 0.05 *滚筒内径+ 0.68 *滚筒外径。
由于所述滚筒海绵B1厚度的为滚筒海绵B1外径R1与内径R2之差的一半，其很好兼容了清洁时形变时摩擦力与余留水分时滚筒海绵增加的摩擦阻力导致的功率和阻力增大。
