Background
The split type ceramic toilet bowl refers to a toilet bowl with a water tank and a base separated. At present, after a base of a split type ceramic toilet is manufactured and molded, the tightness of the split type ceramic toilet needs to be subjected to leakage test so as to eliminate the situations that although the situation is difficult to observe by naked eyes, fine cracks and pinholes exist to cause water leakage and peculiar smell of a finished product. At present, vacuum leak detection is adopted in the most common method at home and abroad. The vacuum leak detection is to seal the toilet seat, the water inlet and the sewage outlet by adopting a sealing pressure plate, then connect a vacuum pump, pump the interior of the ceramic toilet to a preset vacuum value, and then close a pipeline channel between the vacuum pump and the interior of the ceramic toilet so as to enable the interior of the ceramic toilet to be in a pressure maintaining state; and detecting by adopting a pressure sensor communicated with the ceramic closestool, and observing whether the pressure value of the pressure sensor changes after a period of time interval, thereby judging whether the leakage detection result of the ceramic closestool meets the requirement.

After the toilet seat, the water inlet and the sewage outlet are tightly sealed by the sealing pressure plate A, B, C, the evacuation inspection link is always in a Y-shaped connection form, namely, a three-way pipe 12 is arranged on one side of an evacuation pipeline 11 connected with a vacuum pump, which is close to the toilet seat sealing pressure plate A, and a first electromagnetic valve 111 is arranged on the evacuation pipeline 11; one end pipeline 121 of the three-way pipe 12 is used for installing the pressure transmitter 13, and the end pipeline 121 is further provided with a branch, the branch is used for connecting a joint D of an exhaust pipe (the exhaust pipe is used for emptying after vacuum leak detection is completed), and the pipeline 121 is provided with a second electromagnetic valve 112 which is used for closing or conducting the exhaust pipe. The other end of the tee 12 is connected to the pipe joint of the sealing pressure plate a of the toilet seat by a pipe 122. The pipelines are connected with each other through embedded joints and PU pipes. When the vacuum leakage is detected, the first electromagnetic valve 111 and the second electromagnetic valve 112 need to be closed for pressure maintaining, so that the pipe joint of the sealing pressing plate A is communicated with the pressure transmitter 13, and the ceramic toilet bowl is subjected to leakage detection through the pressure transmitter 13.
Among the above-mentioned whole vacuum leak hunting system, each solenoid valve is far away from the vacuum cavity body distance of waiting to detect the product, and middle pipeline component is more, for example including embedded joint, three-way pipe, PU pipe, solenoid valve etc. uses a period of back, very easily causes the problem of gas leakage because of the rubber in the pipeline or the ageing problem that causes of plastic element to the pressure loss that can't accurately measure through pressure transmitter judges to be on the end that the product detected has defects such as crackle, still pipeline and pipeline component have the problem of gas leakage.
