Sewage received by the upper vertical pipe 1 enters the turbulence part 31 of the lower vertical pipe 3 from top to bottom through the sewage channel 101, the turbulence part 31 guides water flow to rotate and flow downwards, so that gas or downwards compressed gas contained in the water flow falling quickly in the upper vertical pipe 1 is released, enters the air pressure balancing cavity 203 through the lower vent hole 204, and is communicated upwards to the sewage channel 101 at the upper section through the upper vent hole 204 of the air pressure balancing cavity 203, and differential pressure balance at different positions of the upper part and the lower part of the sewage channel 101 is realized; the sewage received by the branch pipe connector 51 enters the flow disturbing part 31 of the lower stand pipe 3 through the water outlet hole 230 and the lower vent hole 204 of the collecting cavity 202, the water flow is guided by the flow disturbing part 31 to rotate to flow downwards, so that the gas or the gas compressed downwards in the water flow falling quickly in the collecting cavity 202 is released, and enters the air pressure balancing cavity 203 through the lower vent hole 204, and is communicated upwards to the sewage channel 101 at the upper section through the upper vent hole 204 of the air pressure balancing cavity 203, so that the air pressures in the upper section and the lower section of the sewage channel 101 and the collecting cavity 202 are communicated and balanced through the water outlet hole 230, the lower vent hole 204 and the upper vent hole 210 which are communicated with each other, and the problem that the sewage in the sewage channel 101 is flushed into the collecting cavity 202 due to air pressure difference to cause sewage backflushing into a user room, or the water-sealed liquid in the collecting cavity 202 is sucked out to cause water sealing function failure is avoided.
As can be seen from the above description of the specific embodiments, the collector of the assembled same-layer drainage collector provided by the invention is assembled by a plurality of split pipe fittings, and a relatively complex structure can be formed inside the collector, so that the collector can be integrated with multiple functions, and the collector is convenient to produce and improve the production yield; a collecting cavity 202 is formed in the collector, and a water seal cavity is formed in the collecting cavity 202, so that odor in the sewer can be prevented from overflowing into a room through the collecting cavity 202; the collector is provided with an air pressure balance cavity 203, the air pressure balance cavity 203 is used for balancing the pressure difference between the upper section and the lower section of the sewage channel 101 and the collection cavity 202, and the phenomenon that sewage in the sewage channel 101 is flushed into the collection cavity 202 due to the air pressure difference to cause the sewage to backflush into a user room until or water seal liquid in the collection cavity 202 is sucked out to cause water seal function failure is avoided.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
