A water gap is left between the flexible attachment and the inner wall of the sewage cavity. A sewage outlet connected to the sewage cavity is opened at the lower end of the end cover, and a sewage cover for opening and closing the sewage outlet is arranged on the sewage outlet. A sewage discharge structure is arranged between the sewage cavity and the end cover, which can vibrate the dirt off the flexible attachment without opening the end cover and discharge the dirt along the sewage outlet.

[0007] Further improvements are: the sewage discharge structure includes an extrusion block and a rapping rod, the extrusion block is movably arranged at the left end of the sewage discharge chamber, the extrusion block is evenly provided with water-permeable holes for water to pass through, the rapping rod is inserted into the flexible attachment, the left end of the rapping rod is detachably arranged on the extrusion block, the end cover is provided with a rapping channel for the right end of the rapping rod to pass through, the rapping channel is provided with a sealing structure to prevent water from seeping out, and the right end of the rapping rod is detachably provided with a driving block that is convenient for driving the rapping rod to drive the extrusion block to extrude the flexible attachment.

[0008] A further improvement is that: a water inlet space is opened inwardly on the left end surface of the extrusion block for the water supply body to evenly pass through the water permeable holes.

[0009] A further improvement is that the movable sleeve on the rapping rod is provided with at least one extrusion sheet for increasing the rapping effect on the flexible attachments, the extrusion sheet is arranged between adjacent flexible attachments, and water holes are evenly opened on the extrusion sheet.

[0010] A further improvement is that the sealing structure is a rubber sealing sleeve, and the rubber sealing sleeve is fixedly arranged on the inner wall of the rapping channel.

[0011] A further improvement is that a driving handle which is convenient for hand gripping is provided on the driving block.

[0012] A further improvement is that the flexible attachment is a sponge block.

[0013] A further improvement is that the end cover is detachably and hermetically connected to the right end of the shell via threads.

[0014] A further improvement is that the drain cover and the drain port are detachably and hermetically connected via threads.

[0015] By adopting the above technical solution, the beneficial effects of the utility model are:

[0016] In this solution, the pores on the sponge block can block impurities in the water body for attachment, so as to collect impurities in a centralized manner, reduce scale adhesion to the inner wall of the pipe in the chiller, and improve the cooling efficiency of the chiller. After the impurities have been attached for a period of time, without disassembling the device, the vibrating rod is driven to reciprocate left and right to squeeze the vibrating sponge block, so that the impurities on the sponge fall off into the water body as much as possible, and then the sewage cover is opened to continue squeezing the sponge block to discharge the sewage from the sewage outlet. The sewage discharge process does not require the disassembly of parts, which greatly simplifies the sewage discharge operation and improves the sewage discharge efficiency.

[0017] A further beneficial effect is that the squeezing sheet movably mounted on the rapping rod between the sponge blocks can improve the sewage discharge efficiency, allowing the middle sponge section to be deformed as a whole under the mutual squeezing of the sponges, thereby improving the sewage discharge efficiency.

[0018] Further beneficial effects: the rapping rod and the extrusion block and the middle of the extrusion sheet are all detachably arranged, so that the sponge block can be easily replaced. BRIEF DESCRIPTION OF THE DRAWINGS
