Though, utilize this filter cover to reach the purpose of draining water and filtering hair, vegetable dregs... and other sundries. However, after a period of use, soap scum and scale mixed with hair, sundries, etc. may cause a drain hole inside the main body to be blocked. And once the drain hole is blocked, the maintenance personnel must use a tool (screwdriver) to remove the lock bolt and the filter cover in sequence, and then use a spring-like flexible tool to open the gap between the fixing ring and the bracket. In order to carry out the cleaning operation.

But in fact this sinking head has the following deficiencies:

1. In order to cover and fix the fixed ring piece of the base to the outside of the shoulder, a special processing machine must be used, the processing is relatively complicated and the manufacturing cost is high.

Two, the size of the flexible tool used for dredging the blockage cannot be too large, otherwise it cannot pass smoothly through the gap between the fixed ring sheet and the support, but the size of the flexible tool is too small and may affect the cleaning effect.

3. When clearing the silt, the locking bolt must be removed first, and then the filter cover can be detached from the base. The locking bolt is small in size, and it is easy to fall into the drain hole during operation, or even lost, so Care must be taken during operation.
