s2, the blocking sensing sheet 203 is further sunken inwards to enable the linkage rotating shaft 206 to drive the strip-shaped cleaning brush 212 to rotate, so that the strip-shaped cleaning brush 212 cleans the filter screen 201;
s3, the blockage sensing sheet 203 further sinks inwards and simultaneously touches the warning switch 213, so that the warning lamp 215 is lightened to warn, and further, the staff is reminded that the filter screen 201 is blocked;
s4, if the warning lamp 215 is turned on, the warning lamp is automatically turned off, which indicates that the filter screen 201 is cleaned by the strip-shaped cleaning brush 212, the blockage of the filter screen 201 is eliminated, and the pump body 101 can be continuously used;
s5, if the warning light 215 is not turned off automatically after being turned on, the pump body 101 is closed and the filter screen 201 is manually cleaned.
The invention is provided with a specially-made blockage sensing sheet 203, the blockage sensing sheet 203 can sense the blockage of the filter screen 201, when the filter screen 201 is blocked, the blockage sensing sheet 203 is further sunken inwards, the blockage sensing sheet 203 is further sunken, not only can the strip-shaped cleaning brush 212 brush along the surface of the filter screen 201, and further automatically clean the filter screen 201, but also can automatically light the warning lamp 215 to warn so as to inform workers in time that the blockage of the filter screen 201 occurs, so that the negative effect caused by the blockage of the filter screen 201 can be obviously reduced, and whether the warning lamp 215 is automatically extinguished can be observed to judge that the filter screen 201 is cleaned by the strip-shaped cleaning brush 212, whether the blockage of the filter screen 201 is solved, and through the arrangement of the impurity removing component 003, the impurities filtered by the filter screen 201 can be taken out under the condition that the pump body 101 is not closed, so that the impurities are convenient to take out, the pollution discharge efficiency can be improved, the blocking phenomenon of the filter screen 201 can be effectively reduced, and the practicability is greatly improved.
The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
