Description

Circulating pipe opening automatic closing device

The present invention relates to an automatic closing device for a circulation pipe mouth, and particularly relates to an automatic closing device for a circulation pipe mouth which is applied to a drain or exhaust pipe mouth to prevent helium, odor, and mosquitoes from entering.

According to the drainage system of every household, it is common to use a water hole cover to block a large amount of foreign matter, so as to effectively reduce the blockage of the drain pipe. However, because the hole in the water hole cover is large, it is unable to effectively prevent foreign matter, hair, etc. from flowing into the drain pipe. Therefore, it often causes blockage; therefore, as shown in the sixth figure, a thin mesh (41) is laid over the water hole cover (4), and the mesh does effectively block the large flow into the drain pipe, but When the water is not drained, the hole of the water hole cover (4) and the mesh (41) is still open, and it is easy to catch pests such as vector mosquitoes and cockroaches for a long time, and it also produces a foul smell due to long-term accumulation of cockroaches. It is easy for the odor, biogas and fumes in the drainage pipe to invade the room. The room is full of disgusting smells, which makes people feel sleepy and even make any disturbing creatures such as cockroaches, mosquitoes, cockroaches, hoppers, snakes, etc. They all have the opportunity to enter the room from here, and these pests will spread diseases such as dengue fever, seriously affecting the cleanliness of the home environment, which is really a big hidden in home security. . Furthermore, in the event of typhoon or heavy rain, sewers and drains may overflow into the room due to insufficient flow velocity, which may seriously affect the indoor sanitation.

Therefore, there is a water hole cover that counteracts the anti-smoke, insect, and deodorization of the Taiwan Patent Publication No. M489890, which includes a top cover and an elastic septum: the top cover is provided with a plurality of holes; the elastic septum is disposed on the The inside of the top cover is a slit having a portion corresponding to each of the holes, so that the elastic spacer at the slit forms a valve.

Because of this, there is an insect-proof and filtering structure of a falling head cover as disclosed in Taiwan Patent Publication No. M514483, which is a water-falling hole that is coupled to the body of the falling head, and includes: a cover having a coupling hole located at the center and located a plurality of drainage holes arranged in a ring shape around the outer periphery of the hole; and a filter mesh disposed on either side of the cover and shielding each of the drainage holes; wherein the cover is provided by the coupling hole to be integrated into the inside of the water hole of the drop head body Fixed, the filter mesh is used to block the reptile from entering the room by the water hole and blocking the blockage caused by the garbage. However, the filter mesh of the above structure can only prevent large mosquitoes from flying into the room, and can also fly into the room through the mesh for a small volume of aphids, so the effect is not good.
