The rotating part may not rotate, and the reminder effect cannot be effectively exerted.

In view of the above shortcomings, the inventor believes that it is necessary to correct it. Based on his many years of experience in related technologies and product design and manufacturing, and adhering to the excellent design concept, he researched and created the above shortcomings. After continuous efforts, he finally achieved Launched the pipeline liquid leakage detection device of the present invention, hoping to correct the product structure and improve the product's excellent efficacy.

The main purpose of the pipeline liquid leakage detection device of the present invention is to provide a leak detection device structure with relatively sensitive rotating parts.

In order to achieve the purpose disclosed above, the pipeline liquid leakage detection device of the present invention includes:

A circulation seat has a seat body, one side of the seat body is recessed with a chamber, the center of the seat chamber protrudes to form a shaft column, the shaft post has a tip, and the outer side of the seat body is extended to form two connecting parts. The connection part runs through a passage communicating with the seat chamber, and the two passages are staggered on the shaft column, and the seat body is also recessed with an annular groove surrounding the seat chamber, and the annular groove is equipped with a leak-proof ring;

A rotating part located in the seat has a base, a plurality of blades are formed on the outside of the base, and a shaft chamber and an air chamber are recessed at one end of the base, and the air chamber surrounds the shaft chamber;

a closed ring installed in the air chamber;

A shaft sleeve has a sleeve body with a circular cross-section, the sleeve body defines a set of chambers, the sleeve is installed in the shaft chamber, and the sleeve is also sleeved in the shaft column with the sleeve chamber;

A cover plate is fixedly arranged on the seat body and abuts against the leak-proof ring, so that the cover plate covers the seat chamber.

The flow seat is used to be installed in the liquid pipeline between the toilet tank and the water source, so when the toilet is flushed, the water can flow from the water source to the water tank through the flow seat, and the rotating part will be driven by the water flow to rotate;

And if the water tank leaks, water will continue to flow from the water source through the circulation seat, causing the rotating part to rotate continuously. Therefore, personnel can know whether there is water leakage and need to be repaired by observing the rotating part.

Compared with the previous "water tank leakage detection device", the rotating part of this device has an air chamber to reduce the weight and reduce the friction between the shaft sleeve and the shaft column, so that the rotating part is easier to be detected. The water flow promotes and has high sensitivity, so even if the water tank has only a small amount of water leakage, the rotating part will still rotate to reliably achieve the prompting effect. It can be seen that the present invention is a progressive creation.
