The invention relates to an innovative structure of a drainage filter, in particular to an automatic cleaning function for removing fallen leaves, dead branches or garbage attached to the surface of the drainage filter, thereby avoiding the obstruction 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 siltation of the hole prevents the accumulated water from being discharged. On the contrary, 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 inventors invested a lot of time to study relevant knowledge, and compared various advantages and disadvantages, carried out research and development of related products, and after many experiments and tests, finally launched the "innovation structure of drainage filter" to improve the above-mentioned defects.

A further technical feature of the present invention is that the filter is provided with a cover having an outer diameter that is small and has a tapered shape.

A further technical feature of the invention is that the impeller is of a four-blade turbine blade arranged in an equidistant manner.

In combination with the above technical features described in the present invention, the advantage is that a self-brushing mechanism is disposed on the drain filter, and an impeller that impacts the self-brushing mechanism is provided through a flow of water to be discharged downwardly toward the drain hole. When the impeller is rotated, a cleaning brush is driven around the periphery of the drainage filter to remove debris, dead branches or garbage, which are blocked and attached to the outer peripheral surface of the filter, so that the plurality of through holes are kept open. Therefore, the use of the high-cage type falling head is often caused by the attachment of leaves and the presence of fine debris on the surface, thereby hindering the flow of water to the lower row and causing water accumulation on the ground, resulting in the drainage system losing the drainage function. Therefore, the present invention can be said to be a practical and progressive creation, which is quite worthy of promotion by the industry and is publicized to the public.
