Description

Drainage hole anti-plug device

The invention relates to a drainage hole anti-plug device, in particular to a drainage device capable of preventing foreign matter such as dust, earth and stone, leaves and the like from blocking water accumulation.

Drainage holes are an indispensable equipment for every building. No need to have drainage lines on the roof, balcony, inside or outside the house to drain excess water through the drainage line.

However, although the drainage hole is a standard configuration of a general building, there are often cases where the drainage is unsmooth or the drainage is not smooth. The main reason for the recovery is that the drainage hole cover is blocked by foreign matter, and the accumulated water cannot be discharged through the drainage line. If this situation occurs in the front and rear balconies of the top floor, it will cause water to accumulate on the roof. If the water is not treated for a long time, it will seep into the house and even seep into the downstairs, forming a leak.

Therefore, whether it is necessary to clean the drain hole cover regularly or indoors, the drainage is smooth, but the modern people are busy. The indoor drainage hole cover is cleaned up because of the high chance of use. The chance of blockage is not high, but the drainage hole is located outside. Cover, it is quite easy to forget to clean up, and a considerable proportion of the home will plant potted plants on their balcony. When it rains, it will accumulate in the drainage hole. At the same time, the outdoor is covered with dust, earth and stone, fallen leaves and other debris. Opportunities are also high. If there are idle buildings, it is necessary to regularly maintain the smooth opening of the drain hole cover.

Referring to FIG. 1 , it is a generally common drain hole cover structure. The drain hole cover 10 is a water drop cover 12 and a water guide 11 having a plurality of drain holes 111 and 121 and lock holes 112 and 122 and a lock body 13 . The joint locking holes 112, 122 are interlocked and formed.

However, the end surface of the falling water cover 12 is set to be a flat surface, so that dust, earth and stone, fallen leaves and the like are easily caught in the edge gap of the water-falling cover 12 and the water-conducting water tank 11, and a small amount of foreign matter and dirt are easily accumulated in the drainage. In the flow holes 111 and 121, not only the appearance is unattractive, but also the water is likely to accumulate, and the dirt and debris are stagnant, thereby causing the drainage effect to be deteriorated and the water pipe to generate foul odor. At the same time, the barrier must be removed by hand to clear the barrier. Therefore, the user is unsatisfactory in use and is uncomfortable and inconvenient to clean up.

The above-mentioned outdoor or idle buildings are prone to blockage of the drainage hole cover during the typhoon and heavy rain season. However, if the typhoon is raging, it is very dangerous to go out and clean the drainage hole cover. It is quite difficult to cause water accumulation in the home environment and even lead to water leakage.

In view of this, how to effectively avoid the blockage of the drain hole cover, prevent water accumulation on the roof and balcony, and greatly reduce the chance of cleaning the drain hole cover, and it is an important issue for the present invention to actively improve the drainage of the building.

Accordingly, it is an object of the present invention to provide a drain opening preventing device which can prevent foreign matter from clogging and thereby cause water to accumulate.
