Abstract

The utility model relates to a full-automatic odor blocking device used on the hole of a squatting urinal in a toilet, which can effectively prevent blocking, deodorization and rodent prevention. It is from the inlet hole to the anti-blocking outlet hole and then to the deodorizing outlet hole. The size of the inlet hole depends on the size of the pool hole. The outer circle of the inlet hole should be slightly larger than the urinal hole. To hang or block things, the deodorant outlet hole uses the principle of lever balance, and the plastic disc automatically opens and closes the bottom outlet hole. The anti-blocking outlet hole can effectively prevent the toilet from being blocked, and the anti-odor outlet hole can effectively cover the odor from the sewer pipe, and can also prevent mice from entering the house from the sewer pipe.

Description

Automatic odor blocking device

Technical field

The utility model is a full-automatic odor blocking device used on the hole of a squatting urinal in a toilet. It can effectively prevent blockage, deodorization and rodent prevention.

Background technique

At present, the odor blocking device used by everyone is made of plastic. There are two types of it. One is a ball odor blocking device. It is a plastic odor blocking device installed on the urinal hole. A small exit hole, and then put a small ball to block the small hole. When the water and stool are flushed down, due to the impact of the water, the small ball will automatically leave the round hole, and the stool and water will flow into the downpipe through the small round hole. When there is no water, the ball will automatically return to the small round hole , Block the odor and achieve the deodorizing effect. However, in real life, when the stool is flushed, the stool is easy to stick to the small ball. When the small ball returns to the small hole, there will be stool on the small ball, so it looks disgusting and smelly . Another point is that it is not anti-blocking. When water and cloth strips and other things fall together, due to the impact of the water, the ball will leave automatically, and the cloth strips and other things will fall into the downpipe together with the water and block the water. Downpipe, so it's not clogproof. Another kind of odor blocking device, which looks similar to a bowl, is characterized in that a spring is connected with a circular plastic plate by a pin and fixed on one end outside the outlet hole at the bottom of the device. The circular plastic plate The board seals the outlet hole at the bottom. When something falls, the circular plastic board will automatically open under the influence of the force of the falling thing. When it opens, one end of it will compress the spring. When there is no more thing, The circular plastic plate will be automatically returned to its original position by the rebound force of the spring, and the outlet hole will be covered to achieve the anti-odor effect. However, because the bottom outlet hole is to be sealed, the elastic force of the spring must be large. When the force of the falling thing is not large, it is easy to be stuck, and it must be washed away with a large amount of water, so it is a waste of water. Trouble again. And because the spring is metal, it is easy to rust when it contacts with water and humid air for a long time, and the elastic force of the rusty spring will weaken, and the outlet hole cannot be completely sealed when the elastic force weakens, so the odor blocking effect of this odor blocking device is not very good. ideal. The most important thing is that it is not anti-blocking, when water and cloth and other things fall together, the circular plastic plate will be opened automatically by the impact of water, so the cloth and other things will fall into the downpipe , to block the drain pipe.

Contents of the invention

In order to overcome the shortcomings of the above two kinds of odor blocking devices, the utility model provides a fully automatic odor blocking device, which can not only prevent blockage and deodorization, but also prevent mice from entering the house from the sewer pipe.

The technical solution adopted by the utility model to solve its technical problems is: the odor blocking device is also made of plastic, and it is composed of a hollow plastic shell connected with a circular plastic board, and its upper hole is for entering The outer circle of the inlet hole is slightly larger than the urinal hole, and it is flush with the edge of the urinal hole, so that the odor blocking device will not fall into the sewer pipe, and will not prevent stool and water from falling into the sewer pipe . The middle part of the hole is an anti-blocking exit hole, its diameter is designed to be 5.2 cm, and its length is 3 mm. A total of 6 needle-like plastic needle points are evenly placed around the hole wall at 3 mm. The needle points rise obliquely and are flush with the exit hole. The distance between the needle tip and the hole wall is 2 mm. Because the hole is 5.2 cm large, things that are slightly larger will not fall, and things that are slightly smaller and cloth strips will be caught or blocked by the plastic needle point, and because the needle point is sharp and the distance from the hole wall is 2 mm , so when the stool and water are flushed down, it will not affect the falling of the stool. In order to prevent the odor from entering the house from the downpipe, it is necessary to seal the outlet hole at the bottom. The outlet hole at the bottom of this odor blocking device is designed as a semicircle, and it is sealed with a circular plastic plate. The circular plastic plate Use a pin to hang and fix one end outside the bottom outlet hole. The circular plastic board is slightly larger than the bottom outlet hole and is designed to be slightly heavier at one end than the other. Using the principle of lever balance, when nothing falls from above , the heavy end will lift the light end, and the bottom outlet hole will be automatically sealed. When something falls from above, the falling force is greater than that of the other end, and it will automatically open, so it realizes fully automatic opening and closing. It also solves the problem of odor transmission from the bottom to the top, and truly achieves the anti-odor effect.

The beneficial effect of the utility model is that it can effectively prevent blockage, deodorize and prevent rats, and it is fully automatic.
