That is, the distance between the adjacent limiting walls 121 is not enough to allow the floating member 3 to pass through, so that the floating member 3 is prevented from being excessively displaced relative to the reed pipe 2 in the horizontal direction, and the accuracy of detecting the washing liquid is prevented from being influenced. Meanwhile, the spacing walls 121 arranged at intervals enable the spacing area where the floating piece 3 is located to be better communicated with the chamber, so that the floating piece 3 can more accurately reflect the liquid level height of the washing liquid in the washing agent box 1, and the detection is more accurate. It is to be construed that the minimum distance between two opposite faces on the outline of the floating member is, if the floating member is a polyhedron, the minimum distance between two opposite faces on the floating member is the distance between the nearest opposite planes on the polyhedron. If the floating piece is a cylinder, the diameter of the cylinder is smaller than the height of the cylinder, and the minimum distance between two opposite surfaces on the floating piece is the diameter of the cylinder; if the diameter of the cylinder is greater than the height of the cylinder, the minimum distance between two opposite faces on the float is the height of the cylinder. If the float member is a sphere, the minimum distance between two opposite surfaces on the float member is the diameter of the sphere. If the floating member is a hemisphere, the minimum distance between two opposite surfaces on the floating member is the radius on the hemisphere.

It is to be construed here that the maximum distance between two opposite faces on the contour of the floating member is, if the floating member is a polyhedron, the maximum distance between two opposite faces on the floating member is the distance between the opposite planes on the polyhedron that are most distant from each other. If the floating piece is a cylinder, the diameter of the cylinder is smaller than the height of the cylinder, and the maximum distance between two opposite surfaces on the floating piece is the height of the cylinder; if the diameter of the cylinder is greater than the height of the cylinder, the maximum distance between two opposite faces on the float is the diameter of the cylinder.
