Description

Drain filter structure

The invention relates to a drainage filter structure, in particular to an automatic cleaning function for removing fallen leaves, dead branches or garbage and the like attached to the surface of the drainage filter, thereby avoiding 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 silt of the hole prevents the accumulated water from being discharged, but the water head causes the water to flow to the lower row to cause water accumulation on the ground. The falling head loses its drainage function, so 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 research 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 "drainage filter structure" to improve the above-mentioned defects, In order to meet the needs of the public.

The main object of the present invention is to provide a drainage filter structure, which has an automatic cleaning function, which can remove the fallen leaves, dead branches or garbage attached to the surface of the drainage filter, and can avoid the blockage of debris and affect the drainage. The function can prevent garbage, leaves and other debris from falling into the drainage hole, avoiding the drainage hole blocking and providing better drainage effect.

Therefore, in order to achieve the above object and effect, the drain filter structure of the present invention is configured to be disposed on a drain hole of a floor or a balcony, and includes: a filter fixed on the drain hole, the filter The utility model is characterized in that: a high-cage-shaped cover body is oppositely protruded from the drainage hole, the filter is provided with a perforation at the center, a plurality of through holes are arranged at the periphery, and a plurality of through holes are communicated with the drainage hole; a self-brushing mechanism includes a driving spindle, an impeller and a cleaning brush; the cleaning brush is in the shape of a crank, one end is provided with a cross-shaped pivot hole, and the other end has a plurality of bristles, the plurality of bristles can be in contact with the outer periphery of the filter; the transmission spindle A threaded portion, a pivoting portion and a through portion are sequentially disposed from the top to the bottom, and the through portion can pass through the through hole of the filter, and the pivoting portion is disposed in a cross shape to pass through the pivot of the cleaning brush After the hole is connected, a bearing is additionally sleeved, and a nut is screwed to the threaded portion. Locking; the impeller having a plurality of turbine blades coupled to the end of the drive spindle; thereby providing impact to the plurality of turbine blades by the flow of water through the plurality of through holes downwardly toward the drain hole Rotating, and interlocking the driving spindle to rotate the cleaning brush around the filter, that is, the plurality of bristles can sweep away the fallen leaves, dead branches or garbage, etc., which are blocked and attached to the outer peripheral surface of the filter, so that the plural The through hole is kept clear, and the drainage hole is prevented from being blocked to ensure the drainage effect of the drainage system.

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.

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.
