Toilet down-exhausting stinking-proof plumbing installation

Abstract

The invention provides an under-exhaust deodorization pipe device for a toilet. The pipe device mainly adopts and comprises a hard PVC drainage pipe that is commonly used in construction field, and the fittings such as a tee joint and an elbow, etc. that are matched with the drainage pipe; wherein, one end of an air intake of the pipe device is communicated with a squat ware, and one end of an air outtake is communicated with a ventilator. When people use the toilet, the ventilator is opened, negative pressure is formed in an air drainage pipe, and the bad smelly in the ware can be discharged outside the room via the air drainage pipe. The invention has the advantages of simple structure, convinient installation, low cost, beautiful appearance, and timely and complete deodorization, and is applicable for being popularized and used.

Description

technical field [0001] The invention relates to a building deodorizing exhaust duct, and more specifically relates to a duct device installed in a toilet to completely eliminate odor through a set of exhaust pipes and pipe fittings connecting a toilet and a ventilation fan. Background technique [0002] For a long time, the bathroom odor problem that plagues people has not been universally, effectively and thoroughly solved. The better solution to this problem in the currently known technology is to use the lower exhaust method, casually search the patent documents published by the State Patent Office, and find that there are at least 500 patent documents related to the lower exhaust air deodorization pipeline and toilet. There are so many kinds, but people rarely see the application of this kind of patented technology in real life. From the above data, we can see people's great desire to solve this problem from one aspect, and on the other hand, it also reflects the current...

[0002] For a long time, the toilet odor problem that plagues people has not been universally, effectively and thoroughly solved

The better solution to this problem in the currently known technology is to use the lower exhaust method, casually search the patent documents published by the State Patent Office, and find that there are at least 500 patent documents related to the lower exhaust air deodorization pipeline and toilet. There are so many kinds, but people rarely see the application of this kind of patented technology in real life. From the above data, we can see people's great desire to solve this problem from one aspect, and on the other hand, it also reflects the current solution. The existing patented technology for this problem has some defects in practical application. If you analyze the reasons carefully, you can find that there are mainly deficiencies in the treatment of the exhaust pipe, which leads to the existence of other problems. One is the exhaust pipe. If it is set smaller, due to the limitation of its own structure, the diameter of the exhaust pipe is relatively small in such patent documents, so generally only high-speed fans can be used, but the overall exhaust air volume is still small, the exhaust effect is not ideal, and the high-speed Fans are generally suitable for industrial use. As daily use, there are many defects in safety, life, cost, installation, noise, maintenance, etc. The other is that the diameter of the exhaust pipe can be set larger. Such patent documents are mainly in There are major deficiencies in installation, appearance treatment, cost, etc., or the unsatisfactory effect is caused by the fact that the air inlet of the exhaust pipe is far away from the urinal, which also makes it difficult to be widely used.
