Description

Technical Field

[0001] The utility model relates to the technical field of PVC drainage pipes, in particular to an indoor PVC drainage pipe with a noise reduction structure. Background Art

[0002] Indoor drainage pipes are mostly made of PVC. PVC drainage pipes are made of sanitary polyvinyl chloride (PVC) resin as the main raw material, with appropriate amounts of stabilizers, lubricants, fillers, color enhancers, etc., and are extruded by plastic extruders and injection molded by injection molding machines. Because they are not easy to clog and have good anti-aging effects, they are widely used and can be seen everywhere in every household.

[0003] However, in the existing PVC drain pipe, water flow will hit the inner wall of the PVC drain pipe during drainage, thereby generating a large noise. When the drainage volume is too much, the drain pipe will shake due to the impact of the water flow, causing the PVC drain pipe to fall off the wall, resulting in poor use effect. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technical solutions, the utility model provides an indoor PVC drain pipe with a noise reduction structure, which can effectively solve the technical problems of the existing PVC drain pipe in which the water flow will hit the inner wall of the PVC drain pipe during the drainage process, thereby generating a large noise; when the drainage volume is too much, the drain pipe will shake due to the impact of the water flow, causing the PVC drain pipe to fall off the wall, resulting in poor use effect.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an indoor PVC drainage pipe with a noise reduction structure, comprising a guide pipe and a diversion pipe, the diversion pipe is hollow inside and is provided with a first drainage part, an inner pipe is provided in the middle of the diversion pipe, the middle of the inner pipe is hollow to form a drainage channel, the first drainage part is spirally coiled around the outer wall of the inner pipe, a first diversion channel is formed between the first drainage part and the outer wall of the inner pipe, the guide pipe is hollow inside and is provided with a second drainage part, the inner pipe is arranged inside the guide pipe, the second drainage part is spirally coiled around the outer wall of the inner pipe, a second diversion channel is formed between the second drainage part and the outer wall of the inner pipe, and the first diversion channel and the second diversion channel are connected to each other.

[0006] Preferably, the first drainage portion and the shunt tube are an integrated structure, and one end of the inner tube close to the shunt tube is connected to the first drainage portion.

[0007] Preferably, the second drainage portion and the drainage tube are an integral structure, and the second drainage portion is in contact with the outer wall of the inner tube but not connected.

[0008] Preferably, the shunt pipe is disposed at one end of the flow guiding pipe and is interconnected therewith, and the outer diameter of the shunt pipe is consistent with the outer diameter of the flow guiding pipe.

[0009] Preferably, the width of the first drainage portion is consistent with the width of the second drainage portion.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] By arranging the guide pipe and the diversion pipe, when the drainage volume is large, a part of the water flows along the drainage channel for drainage, and the other part of the water flows into the second drainage part along the first diversion channel under the guidance of the first drainage part, and then is discharged from the bottom end of the guide pipe along the second diversion channel. Under the effect of diversion, the drainage volume can be effectively shared, and the phenomenon of water hitting the inner wall of the PVC drainage pipe to generate noise during the drainage process can be reduced. On the other hand, the second drainage part can fix the inner pipe so that the inner pipe will not shake due to the impact of the water flow, thereby further improving the overall noise reduction effect of the PVC drainage pipe.
