This creation is about the structure of the drainage filter, especially an automatic cleaning function to remove the fallen leaves, dead branches or garbage attached to the surface of the drainage filter to avoid the blockage of the drainage hole to ensure the drainage effect of the drainage system.

According to the generally known drainage filter (commonly known as the falling head), the function is to discharge the accumulated water inside and outside, and can effectively block the larger foreign matter during the discharge of the accumulated water, so as to prevent the foreign matter from blocking the drainage channel. The conventional falling head is divided into a flat type and a high cage type. The high cage type falling head usually comprises: a base and a filter, the base has a water hole for water supply and drainage, and the filter protrudes from the ground and is provided with a plurality of The boring hole can communicate with the water sluice hole; the filter blocks the debris such as fallen leaves, dead branches or garbage, so that the fallen leaves, dead branches or garbage can pass through the boring holes and the water holes and fall into the drainage holes. It can prevent the drainage hole from being fouled and hinder the drainage. However, the filter originally used to block debris, dead branches or garbage from falling into the drain hole is often blocked by the excessively attached leaves on the surface of the filter, or the small debris is stuck. The pupils are such that because the pupils are shielded, there is no channel through which the water can be drained. The accumulated water accumulates on the ground and cannot be drained. Once the water reaches a certain height, it will even be recharged into the house, and the result is not drainage. The hole is blocked, so that the water cannot be drained. However, it is because the falling head blocks the flow of water to the lower row and causes water to accumulate on the ground, so that the falling head loses the drainage effect. Therefore, the structure of the drain filter (falling head) is necessary to be improved.

In view of the above situation, the creator invested a lot of time to study relevant knowledge, and compared various advantages and disadvantages, research and development of related products, and after many experiments and tests, finally launched the "drain filter structure" to improve the above-mentioned defects, In order to meet the needs of the public.
