Abstract

The invention provides a suction device with a real-time gas pressure detection function. The device comprises a suction loop part and a singlechip control part and structurally comprises a urine/stool treating cavity, a recycling barrel, a solenoid valve, an energy storage tank, a pressure sensor, a filter, a gas pump, a muffler and the singlechip control part of an intelligent urine/stool treating device, wherein the urine/stool treating cavity is connected with the recycling barrel by virtue of a water pipe; the recycling barrel, the solenoid valve, the energy storage tank, the filter, the gas pump and the muffler are connected by virtue of gas pipes according to a gas inlet/outlet mode; the pressure sensor is connected with the internal thread of the energy storage tank by virtue of an external thread; and the pressure sensor is connected with the singlechip control part by virtue of a lead. The device has a concise structure and higher degree of automation, is convenient to use, can be used for realizing the suction of the flushing water in the water pipe between the urine/stool treating cavity and the recycling barrel in the intelligent urine/stool treating device, has a better suction effect and has a certain fault self-rescue function.

Description

technical field [0001] The invention relates to a suction device with a real-time gas pressure detection function, which is used to solve the problem of flushing water suction in a water pipe between a urine and stool processing cavity and a recovery bucket in an intelligent urine and stool processing device. Background technique [0002] In the prior art, the flushing water suction method in the water pipe between the urine and feces treatment chamber and the recovery bucket in the intelligent urine and stool treatment device is to add a solenoid valve between the recovery bucket and the air pump, and the energy storage tank and the air pipe form an air path , first close the solenoid valve to prevent outside air from entering, start the air pump to start pumping air from the air pipe and energy storage pump, and after a period of suction, the entire air circuit will form a certain negative pressure. Then open the electromagnetic valve, due to the effect of negative pressur...
