As a preferred scheme of the utility model, the connecting bolts 100 have six roots, and the size of the connecting bolts 100 is adapted to the channel cover plate 200, the connecting bolts 100 are located outside the channel three 210 and the channel four 220, so that the channel six 350 can have space to connect the channel five 370 and the side wall of the head 400.
[0046] The multiple groups of channels can increase the flow of cleaning agent, which can better flush and soften the sludge, and also increase the liquid pressure, which facilitates the flow of the cleaning agent when it flows out. As a preferred scheme of the utility model, the channel five 370 and the channel six 350 have four groups, the channel five 370 is adapted to the size of the main body 300, and the channel six 350 is adapted to the size of the head 400.
