Description

A respirator that maintains stable air pressure in the pipeline

technical field

The present invention relates to a stool treatment technology.

Background technique

Existing buildings, the septic tanks are equipped with exhaust gas discharge pipes directly to the roof, so as to discharge the foul gas generated in the septic tanks into the sky, so as to avoid these foul gases polluting the living environment of the residents, and the exhaust gas will contain viruses . To this end, a gas purifier that can kill viruses has been invented. By heating, the viruses in the foul gas flowing through are killed at a set temperature for a period of time. Due to the need to stay at high temperature for a sufficient time to fully kill the virus in the dirty gas, a device for controlling the flow rate of the dirty gas is required. Under normal circumstances, the device will not affect the flushing of the toilet in the building. However, in some special occasions, such as the rainstorm causes the water in the septic tank to overflow the defecation pipe, because the flow rate of the gas controlled by the device is very low, the phenomenon of gas blockage occurs, which leads to the occurrence of gas blockage in the urinal. Excrement cannot be flushed into the defecation pipe smoothly; for another example, when there are flushing toilets in multiple buildings in the same building at the same time, the excrement that flushes into the defecation pipe and moves down will cause the defecation pipe to form negative pressure. When the flow rate of the gas controlled by the device is very low, the negative pressure in a short period of time is relatively large, and it is easy for the excrement to stay in the pipe, and the accumulated excrement will cause the blockage of the defecation pipe. To this end, a control mechanism that can automatically control the air pressure in the drainage pipeline to maintain stability has been invented. The control mechanism includes an electric valve, a control device, and an air pressure sensor. Although the control mechanism can solve the above problems, it has a complex structure, and is difficult to manufacture and use. high cost.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a respirator that can automatically adjust the air pressure in the defecation pipe to ensure that the excrement in the toilet of the building is smoothly flushed into the defecation pipe, with a simple structure and low cost to keep the air pressure stable in the pipe .

The present invention is realized by including a main trachea, an expiratory respirator and an inspiratory respirator arranged on the main trachea. An outer annular groove, an outer bracket arranged on the outer side wall of the main trachea, an outer cap buckled in the outer annular groove, a spring arranged between the outer cap and the outer bracket, the inhalation respirator includes an inhalation port arranged on the main trachea side wall An inner annular groove filled with sealing liquid on the inner side wall, an inner bracket arranged on the inner side wall of the main trachea, and an inner cap fastened in the inner annular groove.

A spring is arranged between the outer cap and the outer bracket.

A spring is arranged between the inner cap and the inner bracket.

When in use, connect the inlet and outlet of both ends of the main air pipe to the outlet of the exhaust gas discharge pipe and the inlet of the gas purifier respectively. At the same time, the toilet in the building is flushing the excrement), the air pressure in the exhaust pipe overcomes the gravity of the outer cap (when setting the spring, the elastic force of the spring is also required), and pushes the outer cap away from the outer annular groove. The exhalation port is opened to avoid the formation of air lock due to the high air pressure in the exhaust pipe, so that the excrement cannot be flushed into the exhaust pipe; when the air pressure in the exhaust pipe is lower than the set value (in the same building At the same time, the toilets are flushed in multiple buildings, and the excrement that flushes into the defecation pipe and moves down will cause excessive negative pressure in the defecation pipe), and the air pressure in the exhaust gas discharge pipe overcomes the gravity of the inner cap (when setting the spring, at the same time The elastic force of the spring is required), push the inner cap away from the inner annular groove, so that the suction port is opened, so as to avoid the negative pressure in the exhaust gas discharge pipe, which can prevent the excrement from falling into the septic tank smoothly and stay in the exhaust gas discharge pipe. .

Compared with the prior art, the present invention can automatically adjust the air pressure in the defecation pipeline because it does not need electric valves, sensors and corresponding control devices, so as to ensure that the excrement in the toilet of the building is smoothly flushed into the defecation pipeline Therefore, it has the advantages of being able to automatically adjust the air pressure in the defecation pipe to ensure that the excrement in the urinal of the building is smoothly flushed into the defecation pipe, and has the advantages of simple structure and low cost.
