Detailed Description

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, the terms "upper", "lower", "front", and "rear", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention but do not require that the present invention must be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

The following further describes embodiments of the present invention with reference to the drawings.

Example 1:

referring to fig. 1 to 14, the present embodiment provides a toilet drain collection system which is inscribed between sewage main drain lines and is in up-and-down communication with the main drain lines when actually installed. The drainage pipe comprises a drainage pipe component 1, a horizontal pipe drainage component 2 communicated with the drainage pipe component 1, and a water seal component 3 communicated with the horizontal pipe drainage component 2. In the present embodiment, the sewage refers to water discharged from a toilet, and the waste water refers to water discharged from a shower, a sink, or the like.

The drain pipe assembly 1 described with reference to fig. 1-8 comprises a first inlet pipe 11, a second inlet pipe 12, a first riser pipe 13 and a second riser pipe 14; the first water inlet pipe 11 is connected with the second water inlet pipe 12 and communicated with the inside of the first water inlet pipe, and the inner edge of the second water inlet pipe 12 is tangent to the inner edge of the first water inlet pipe 11, so that sewage can flow into the first water inlet pipe 11 along the inner wall of the second water inlet pipe 12; the first water inlet pipe 11 is connected with the first vertical pipe 13 and is communicated with the interior of the first vertical pipe, the second water inlet pipe 12 can be communicated with a toilet sewage draining exit and is used for receiving sewage of the toilet sewage draining exit, and the sewage enters the first water inlet pipe 11 along the second water inlet pipe 12. In this embodiment, the first water inlet pipe 11 and the second water inlet pipe 12 are an integrally formed structure, and the first water inlet pipe 11 and the first vertical pipe are sleeved and adhered together. In addition, an included angle of 80-100 degrees is formed between the second water inlet pipe 12 and the first water inlet pipe 11, and the second vertical pipe 14 is communicated with the main sewage discharge pipeline to discharge all the sewage collected by the collecting system of the embodiment into the main sewage discharge pipeline.

Further, the pipe wall cavity 15 that second inlet tube 12 and first inlet tube 11 intercommunication department are the volume inflation, when sewage along second inlet tube 12 entering first inlet tube 11, the curvature radius that sewage pasted the pipe wall whirl can be increased in setting up of pipe wall cavity 15, when sewage discharge capacity is big, effectively reduce sewage discharge rate, ensure that sewage can hug closely the pipe wall whirl, avoid because of pipeline curvature radius undersize, sewage when sewage discharge capacity is big directly from the pipeline during direct current discharges and cause the drainage big noise, reduce pipeline life scheduling problem.

Further, the shape of the first water inlet pipe 11 is a funnel-shaped structure with an expanded upper end opening and a reduced lower end opening from top to bottom, the inner diameter of the upper end opening of the first water inlet pipe 11 is larger than the inner diameter of the first vertical pipe 13, and the inner diameter of the lower end opening is close to the inner diameter of the first vertical pipe 13 and can be sleeved with the first vertical pipe 13. The inner diameter of the opening at the upper end of the first water inlet pipe 11 is larger than the inner diameter of the first vertical pipe 13, and the inner diameter is also used for increasing the curvature radius of the sewage when the sewage adheres to the wall of the pipe in a swirling mode, and due to the structure, the swirling radius is gradually reduced when the sewage adheres to the wall of the pipe in a swirling mode, and finally the sewage enters the first vertical pipe 13 and the second vertical pipe 14 in a swirling mode and is discharged into a main sewage discharge pipeline.

Further, a pipe cover 111 is further arranged at an opening at the upper end of the first water inlet pipe 11, a pipe interface 112 is arranged on the pipe cover 111, and the pipe interface 112 is communicated with the first water inlet pipe 11 and is used for being connected with a main drainage pipeline.

Therefore, the internal connection of the toilet drainage collection system to the sewage main drainage pipeline is realized in a specific manner that the pipe connector 112 of the drainage pipe assembly 1 is communicated with the upper main drainage pipeline at the upper end of the collection system, and the second vertical pipe 14 is communicated with the lower main drainage pipeline at the lower end of the collection system, so that the drainage collection system is communicated with the main drainage pipeline up and down. In this embodiment, the upper main drainage pipeline refers to a part of the main drainage pipeline located on the upper side of the drainage pipe assembly 1 with respect to the three-dimensional space of the building, and the lower main drainage pipeline refers to a part of the main drainage pipeline located on the lower side of the drainage pipe assembly 1.

Further, in practical use, the temperature of the sewage discharged into the first vertical pipe 13 varies according to the source, and the temperature of the sewage varies, for example, the temperature of the waste water generated by showering is higher than the temperature of normal domestic water by approximately 30 ℃, and the temperature difference of the sewage causes thermal expansion and cold contraction of the first vertical pipe 13, so that the first vertical pipe 13 is extended or shortened, thereby affecting the sealing property of the connection between the upper-layer main drainage pipeline and the pipe joint 112, and therefore, in order to reduce the influence of the thermal expansion and cold contraction on the overall sealing property of the drainage pipe assembly 1 and compensate the deformation of the first vertical pipe 13 when the temperature of the sewage varies, the drainage pipe assembly 1 further comprises an expansion joint 16, and the expansion joint 16 is inserted into the pipe joint 112; the telescopic joint 16 comprises an outer layer circular pipe 161 and an inner layer circular pipe 162 which are sleeved with each other, the outer layer circular pipe 161 is communicated with an upper layer main drainage pipeline (see fig. 16), the outer layer circular pipe 161 and an upper layer sewage discharge pipe can slide relatively, and the telescopic range of the telescopic joint 16 can reach 102mm at most. In order to improve the sealing performance of the connection between the telescopic joint 16 and the upper-layer main drainage pipeline, a sealing ring 163 is arranged on the inner wall of the upper end of the telescopic joint 16.

Further, in order to avoid the upper drainage pipe sewage rotational flow to enter the first water inlet pipe 11, or when sewage enters the first water inlet pipe 11 from the rotational flow of the second water inlet pipe 12, sewage can rush out of the second water inlet pipe 12 along the junction of the first water inlet pipe 11 and the second water inlet pipe 12, resulting in sewage convection, the drainage pipe assembly 1 in this embodiment further comprises a baffle 113, the baffle 113 is arranged between the internal connection of the first water inlet pipe 11 and the second water inlet pipe 12. After the baffle 113 is arranged at the joint of the second water inlet pipe 12 and the first water inlet pipe 11, sewage in the second water inlet pipe 12 can enter the first vertical pipe 13 according to a set direction, the sewage in the first water inlet pipe 11 is prevented from reversely entering the second water inlet pipe 12, and the cyclone direction of the sewage entering the first vertical pipe 13 is the same as the cyclone direction of the sewage in the first vertical pipe 13.

Further, when the drainage pressure (the drainage pressure is, when sewage flows along the wall) of the upper-layer main drainage channel into the first water inlet pipe 11 is greater than the drainage pressure of the second water inlet pipe 12 into the first water inlet pipe, the water flow of the first water inlet pipe 11 may flow reversely into the second water inlet pipe 12. In order to avoid the above situation, the drain pipe assembly 1 in this embodiment further includes a pressure stabilizing film 114 disposed at the connection portion of the second water inlet pipe 12 and the first water inlet pipe 11, where the material of the pressure stabilizing film 114 is not particularly limited, and the pressure stabilizing film 114 in this embodiment is made of a flexible material. When the sewage in the second water inlet pipe 12 enters the first water inlet pipe 11, the pressure stabilizing film 114 does not influence the sewage to enter the first water inlet pipe 11 along the pipe wall cavity 15. When the drainage pressure of the first water inlet pipe 11 is greater than that of the second water inlet pipe, sewage in the first water inlet pipe 11 impacts the pressure stabilizing film 114, and the pressure stabilizing film 114 prevents the sewage in the first water inlet pipe 11 from entering the second water inlet pipe 12 due to pressure difference, so that the sewage can be stably discharged from the first vertical pipe 13 in a wall-attached rotational flow manner; when the drainage pressure in the first water inlet pipe 11 is equal to the drainage pressure of the second water inlet pipe, the pressure stabilizing membrane 114 is in a normal assembly state, and the drainage of pipeline sewage is not influenced; when the drainage pressure in the first water inlet pipe 11 is less than the drainage pressure of the second water inlet pipe, the pressure stabilizing membrane 114 is impacted by the sewage discharged by the second water inlet pipe 12 and is sunken inwards along the radial direction of the first water inlet pipe 11, so that the discharge space of the second water inlet pipe 12 is enlarged, and the final wall-adhering rotational flow of the sewage is ensured to be stably discharged from the first vertical pipe 13. In addition, when the discharge amount of sewage in the first water inlet pipe 11 attached to the inner wall of the first water inlet pipe 11 and the spiral flow velocity are large, the air flow is disturbed to form negative pressure suction force, and meanwhile, the sewage discharge pressure of the pipe wall formed by the large discharge amount to the sewage is large, when the pressure stabilizing film 114 is not arranged, because the negative pressure suction force and the drainage pressure are dispersed on the contact surface of the negative pressure airflow, the pipe wall and the sewage and cannot be mutually offset, the toilet water seal is easily sucked by the negative pressure to cause the failure of the toilet water seal, the arrangement of the pressure stabilizing film 114 causes the negative pressure suction force and the drainage pressure to jointly act on the pressure stabilizing film 114, and the three rigidity forces of the pressure stabilizing film 114 are mutually offset, so that the effect of reducing the fluctuation of the air pressure in the second water inlet pipe 12 is achieved, the system damping is increased, and the risk of the failure of the toilet water seal caused by the negative pressure suction is reduced. When being the malleation in the first inlet tube 11, the steady voltage membrane 114 radially outwards expands along first inlet tube 11 to reach and alleviate the undulant mesh of pressure in the second inlet tube 12, increase system damping, reduce the closestool water seal and lead to the risk of inefficacy because of the malleation splash.

Further, the first vertical pipe 13 and the second vertical pipe 14 in this embodiment both adopt a single vertical pipe, and thus, the functions of drainage and exhaust can be simultaneously realized, and the building space is remarkably saved.

In the drainage pipe assembly 1 of the embodiment, when drainage and exhaust are performed, in order to avoid formation of a water plug (sewage and wastewater are discharged in a swirling manner close to the pipe wall under a normal condition, and when swirling is discharged, a hollow air column is formed to discharge waste gas, but if sewage/wastewater is not discharged in a swirling manner close to the side wall of the first vertical pipe 13 or the second vertical pipe 14, and is directly discharged from the hollow part of the first vertical pipe 13 or the second vertical pipe 14, the sewage/wastewater occupies a channel for discharging gas from the first vertical pipe 13 or the second vertical pipe 14, and when waste gas cannot be discharged, the phenomenon that the first vertical pipe 13 or the second vertical pipe 14 is blocked is caused), the pipe wall cavity 15 is provided, so that sewage in the first vertical pipe 13 and the second vertical pipe 14 can be discharged in a swirling manner close to the wall under a high flow condition, formation of the water plug is avoided, the drainage amount is increased, and the generation of drainage noise is reduced.

Referring to fig. 2 and fig. 9-12, the inside of the horizontal pipe drainage assembly 2 in this embodiment is a flat cavity body for collecting the sewage drained by the drainage pipe assembly 1 and the wastewater drained by the water seal assembly 3 into the second vertical pipe 14 of the drainage pipe assembly 1 and draining into the main drainage pipe, one end of the horizontal pipe drainage assembly 2 is communicated with the drainage pipe assembly 1, and the other end is communicated with the water seal assembly; the bottom surface of the cavity of the horizontal pipe drainage component 2 is obliquely arranged, and the height of one end connected with the water seal component 3 is higher than that of one end connected with the drainage pipe component 1. The inclined arrangement of the bottom surface of the horizontal pipe drainage assembly 2 is to reduce the sewage/wastewater temporarily retained in the horizontal pipe drainage assembly 2, so that the wastewater introduced by the water seal assembly 3 flows under the action of self gravity and can smoothly enter the second vertical pipe 14. Moreover, when the sewage discharge amount in the water discharge pipe assembly 1 is large and the water pressure is larger than the water pressure of the wastewater drained by the water seal assembly 3, the sewage can also flow back to the second vertical pipe due to the influence of gravity and is discharged, and the sewage is prevented from being reversely discharged to the water seal assembly 3.

Further, the horizontal pipe drainage assembly 2 comprises a drainage pipe assembly 21 and a water seal assembly 22, wherein the drainage pipe assembly 21 and the water seal assembly 22 are connected together through a connecting piece 27; the drain pipe assembly 21, the water seal assembly 22 and the connecting piece 27 are enclosed together to form a flat hollow cavity structure. In this embodiment, the drain fitting 21 and the water seal fitting 22 are glued to the connecting member 27.

Further, the connecting member 27 is a length-expandable structure. The installer can determine the overall length of the cross tube drain assembly 2 to determine where the water seal assembly 3 is installed by adjusting the length of the connector 27 when installing the collection system.

Further, the bottom surface of the horizontal pipe drainage assembly 2 in this embodiment is obliquely disposed at an angle such that water entering the horizontal pipe drainage assembly 2 can enter the second riser pipe 14 in a tangential direction of the second riser pipe 14, thereby reducing the possibility of water plug formation in the second riser pipe 14.

Further, the drain pipe assembly 21 comprises a first riser interface 211 and a second riser interface 212, and the water seal assembly 22 comprises a waste pipe interface 221; the first vertical pipe 13 of the drainage pipe assembly 1 is communicated with the horizontal pipe drainage assembly 2 through a first vertical pipe connector 211, the first vertical pipe connector 211 can be detached from the drainage pipe assembly 1, and the second vertical pipe connector 212 is communicated with the second vertical pipe 14 and is integrally formed, so that the influence of resistance on flowability of sewage/wastewater at a joint due to a non-one structure is reduced, the sewage/wastewater can be better discharged in a swirling manner along the wall of the pipe and attached to the wall of the pipe, and the possibility of leakage is reduced.

Further, in order to discharge the wastewater deposited on the floor surface into the second vertical pipe 14, the horizontal pipe drainage assembly 2 further comprises an anti-overflow mechanism which is arranged in the cavity and is positioned at the interface (212) of the second vertical pipe, wherein the anti-overflow mechanism comprises an anti-overflow ball seat 23 and an anti-overflow ball 24; the overflow-preventing ball seat 23 is provided with a water accumulation discharge hole 231 communicated with the second vertical pipe 14, and the overflow-preventing ball 24 is placed on the water accumulation discharge hole 231; a water accumulation inflow hole 232 is further formed in the position, corresponding to the water accumulation discharge hole 231, of the drain pipe assembly 21, and the diameter of the water accumulation inflow hole 232 is smaller than that of the anti-overflow ball 24.

Specifically, the anti-spill ball seat 23 is arranged on the inner wall of the second riser 14 communicated with the drain pipe assembly 21; the centers of the water inflow hole 232 and the water discharge hole 231 are located on the same axis.
