Abstract
Description
Technical Field
[0001] This utility model relates to the field of urinal technology, and in particular to a urinal drain pipe assembly, a urinal drain pipe mechanism, and a urinal device. Background Technology
[0002] The urinal is installed on the wall, and the bottom of the urinal trough has a urinal drain outlet. Below the urinal drain outlet is a drain bend, which is connected to the building's sewage pipe. The sewage in the urinal is discharged into the building's sewage pipe through the drain bend.
[0003] Chinese utility model patent CN218643472U discloses a sensor-operated flushing device with anti-siphon function and a sensor-operated urinal. The urinal has a drain pipe connected below its drain outlet. The inlet end of the drain bend is sealed and fixedly connected to the drain pipe outlet, and the drain port of the drain bend passes through a mounting plate to connect to an external sewage pipe. The mounting plate is fixed to the wall, for example, by screws or other fasteners.
[0004] The existing connection method described above has the following drawbacks:
[0005] The drain bend is fixed relative to the drain pipe opening and cannot be adjusted vertically. During on-site installation, in order to ensure that the bottom of the drain bend does not touch the ground when connecting the inlet end of the drain bend to the drain pipe opening, the length of the inlet end of the drain bend needs to be cut on-site according to the height of the drain opening from the ground, which makes installation inconvenient.
[0006] The inlet end of the drain bend is fixed to the drain pipe opening by a cylindrical sealing gasket. After being compressed for a long time, the cylindrical sealing gasket will become thinner, which will affect its fixing effect. Especially in winter, the rubber hardens, the fixing effect becomes weaker, and the drain bend is at risk of falling off. Utility Model Content
[0007] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a urinal drain pipe assembly, a urinal drain pipe mechanism, and a urinal device. The elastic sealing plate of the upper end cover is annular and is used to squeeze the first connecting pipe that passes through the central hole of the elastic sealing plate. The elastic sealing plate gradually slopes downward from the periphery to the center, which acts as a barb and prevents the drain pipe from falling off the upper end cover from the first connecting pipe. During on-site installation, the first connecting pipe can automatically insert into the inlet end of the drain pipe to a certain depth as the urinal falls, so as to adapt to the height of the urinal's drain outlet from the ground. Therefore, there is no need to cut the drain pipe on-site, which facilitates on-site installation.
[0008] This utility model provides a urinal drain pipe assembly, including a drain pipe with a U-shaped bend and a first connecting pipe that extends vertically to connect with the drain outlet of the urinal.
[0009] The inlet end of the sewage bend is equipped with an upper end cover, which includes an end cover sidewall connected to the inlet end and an elastic sealing sheet that is connected to the end cover sidewall and is in the shape of an annulus.
[0010] When the elastic sealing sheet is in its initial state, the radius of the central hole of the elastic sealing sheet is smaller than the radius of the first connecting pipe, and the elastic sealing sheet gradually tilts downward along the direction from the side wall of the end cap to the central hole;
[0011] The lower end of the first connecting tube passes through the central hole and is adjustablely inserted into the inlet end, and the elastic sealing sheet is squeezed and fitted with the first connecting tube.
[0012] In one of the alternative technical solutions, the elastic sealing sheet is connected to the upper end of the end cap sidewall and is integrally formed with the end cap sidewall.
[0013] In one of the alternative technical solutions, the inlet end of the pipe wall is provided with an upward-opening pipe wall slot, and the end cap sidewall is inserted into the pipe wall slot.
[0014] In one of the alternative technical solutions, the surface of the end cap sidewall is provided with a raised lip, which is squeezed into the groove wall of the tube wall slot.
[0015] In one of the alternative technical solutions, the drain bend includes a vertically extending second connecting pipe, the inlet end is located at the upper end of the second connecting pipe, one end of the U-shaped bend is connected to the lower end of the second connecting pipe, and the other end of the U-shaped bend is located on one side of the second connecting pipe.
[0016] In one of the alternative technical solutions, the second connecting pipe is integrally formed with the U-shaped bend.
[0017] The present invention also provides a urinal drain pipe mechanism, including a wall sleeve, a third connecting pipe that can be adjusted to pass through the wall sleeve and is used to connect to the building drain pipe, and the urinal drain pipe assembly described in any of the foregoing technical solutions.
[0018] One end of the third connecting pipe is connected to the outlet end of the sewage bend, and the third connecting pipe is locked to the wall sleeve by a locking element.
[0019] In one of the alternative technical solutions, the third connecting pipe includes a laterally extending main connecting pipe and a connecting pipe elbow integrally disposed at one end of the main connecting pipe and extending downward;
[0020] The connecting pipe elbow is connected to the outlet end, the connecting pipe main tube passes through the wall sleeve, and is locked to the wall sleeve by the locking element.
[0021] In one of the alternative technical solutions, the top surface of the pipe wall at the outlet end is provided with an annular first welding boss, and the bottom surface of the pipe wall of the connecting pipe elbow is provided with an annular second welding boss.
[0022] The second welding boss is welded to the first welding boss.
[0023] The present invention also provides a urinal device, including a wall panel with a mounting hole, a urinal detachably mounted on the wall panel, and a urinal drain pipe mechanism as described in any of the preceding technical solutions;
[0024] One end of the wall-mounting sleeve is installed in the mounting through hole, and the other end of the wall-mounting sleeve is located in the groove on the back side of the urinal;
[0025] The upper end of the first connecting pipe is connected to the drain outlet of the urinal, and the third connecting pipe passes through the wall sleeve and the mounting through hole.
[0026] The above technical solution has the following beneficial effects:
[0027] This utility model provides a urinal drain pipe assembly, a urinal drain pipe mechanism, and a urinal device. The urinal drain pipe assembly includes a drain bend and a first connecting pipe. The inlet end of the drain bend is fitted with an upper end cap. The upper end of the first connecting pipe is used to connect to the drain outlet of the urinal, and the lower end of the first connecting pipe passes through the upper end cap to be inserted into the inlet end of the drain bend. An annular elastic sealing plate is connected to the inner side of the end cap sidewall of the upper end cap. Under normal conditions, the central hole of the elastic sealing plate is smaller than that of the first connecting pipe, and the elastic sealing plate is inclined downward along the direction from the periphery to the center to provide a barb effect.
[0028] When the lower end of the first connecting pipe passes through the central hole of the elastic sealing plate, the central hole can be opened, allowing the elastic sealing plate to press against the first connecting pipe, improving the fixing effect and the sealing and odor-proof effect. In addition, because the elastic sealing plate gradually slopes downwards from the outside to the inside, the first connecting pipe can be smoothly inserted into the inlet end, but is difficult to pull out upwards, thus preventing the drain bend and its upper cap from falling off the first connecting pipe. During on-site installation, the first connecting pipe automatically inserts into the inlet end of the drain bend to a certain depth as the urinal falls, thus adapting to the height of the urinal's drain outlet from the ground. Therefore, there is no need to cut the drain bend on-site, facilitating on-site installation. Attached Figure Description

[0046] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0047] like Figure 1-8 and Figure 16 As shown, an embodiment of the present invention provides a urinal drain pipe assembly, including a drain pipe 1 with a U-shaped bend 11 and a first connecting pipe 2 for connecting to the drain outlet 82 of the urinal 8 and extending vertically.
[0048] The inlet end 13 of the sewage bend 1 is equipped with an upper end cover 3. The upper end cover 3 includes an end cover side wall 31 connected to the inlet end 13 and an elastic sealing sheet 32 connected to the end cover side wall 31 and in an annular shape.
[0049] When the elastic sealing sheet 32 is in its initial state, the radius of the central hole 33 of the elastic sealing sheet 32 is smaller than the radius of the first connecting pipe 2, and the elastic sealing sheet 32 gradually tilts downward along the direction from the end cap sidewall 31 to the central hole 33.
[0050] The lower end of the first connecting tube 2 passes through the central hole 33 and is adjustablely inserted into the inlet end 13, and the elastic sealing sheet 32 is squeezed and fitted with the first connecting tube 2.
[0051] This utility model provides a urinal drain pipe assembly for draining wastewater from the urinal trough 81 of a urinal 8. The bottom of the urinal trough 81 has a drain outlet 82, and the urinal drain pipe assembly is connected to the drain outlet 82 to drain the wastewater from the urinal trough 81.
[0052] The urinal drain pipe assembly includes a drain bend 1 and a first connecting pipe 2. The drain bend 1 can be made of plastic and has a U-shaped bend 11. The U-shaped bend 11 bends upwards, and its bend can hold water, providing a water seal to prevent odors. One end of the drain bend 1 is the inlet end 13, which is installed upwards. The other end of the drain bend 1 is the outlet end 14, which can be installed upwards or horizontally. The outlet end 14 is connected to the building's sewage pipe via the connecting pipe, used to discharge sewage into the building's sewage pipe.
[0053] The first connecting pipe 2 can be made of plastic. The first connecting pipe 2 is a vertical pipe, with its upper end connected to the drain outlet 82 and its lower end inserted into the drain bend 1. Therefore, the first connecting pipe 2 can also be called a sewer pipe.
[0054] Specifically, the first connecting pipe 2 includes a funnel portion 21 and a straight pipe 22 connected below the funnel portion 21. The funnel portion 21 is sealed in the drain outlet 82, and the straight pipe 22 is located at the bottom of the urinal groove 81 and extends downward. The upper end of the straight pipe 22 is provided with a first external thread 23, and a first nut 24 is fitted onto the straight pipe 22 and engages with the first external thread 23. A washer is provided between the first nut 24 and the bottom of the urinal groove 81. After tightening the first nut 24, the first connecting pipe 2 is assembled with the urinal 81.
[0055] The inlet end 13 of the drain bend 1 is fitted with an upper end cap 3. The upper end cap 3 can be made of plastic or rubber. The upper end cap 3 includes a cylindrical end cap sidewall 31 and an annular elastic sealing sheet 32. The elastic sealing sheet 32 can be made of plastic or rubber. The elastic sealing sheet 32 is connected to the inner side of the end cap sidewall 31, and the central hole 33 of the elastic sealing sheet 32 is used for the first connecting pipe 2 to pass downward. When the elastic sealing sheet 32 is in its initial state, that is, when the elastic sealing sheet 32 is not subjected to external force, the radius of the central hole 33 of the elastic sealing sheet 32 is smaller than the radius of the first connecting pipe 2, and the central hole 33 of the elastic sealing sheet 32 is thinner than the first connecting pipe 2. When the elastic sealing sheet 32 is in its initial state, along the direction from the end cap sidewall 31 to the central hole 33, that is, along the direction from the periphery to the center, the elastic sealing sheet 32 gradually tilts downward to provide a barbed effect.
[0056] When the lower end of the first connecting pipe 2 passes through the central hole 33 of the elastic sealing sheet 32, the central hole 33 can be opened, causing the inner edge of the elastic sealing sheet 32 to deform and squeeze the first connecting pipe 2, thus improving the fixing effect and the sealing and odor prevention effect. In addition, since the elastic sealing sheet 32 gradually slopes downward from the outside to the inside, the first connecting pipe 2 can be smoothly inserted into the inlet end 13, but it is difficult to pull it out upward, thereby preventing the drain bend 1 carrying the upper end cap 3 from falling off the first connecting pipe 2.
[0057] During on-site installation, the first connecting pipe 2 automatically inserts into the inlet end 13 of the drain bend 1 to a certain depth as the urinal 8 falls, thus adapting to the height of the drain outlet 82 of the urinal 8 from the ground. Therefore, there is no need to cut the drain bend 1 on-site, facilitating on-site installation. Specifically, during installation, the first connecting pipe 2 is pre-connected to the drain outlet 82. Before installing the urinal 8 onto the wall panel 7, the urinal 8 is first lifted so that the inlet end 13 is aligned with the lower end of the first connecting pipe 2. Then, the urinal 8 is lowered and fixed to the wall panel 7, and the lower end of the first connecting pipe 2 automatically inserts into the inlet end 13, adapting to the height of the drain outlet 82 of the urinal 8 from the ground.
[0058] In one embodiment, such as Figure 6-7 As shown, the elastic sealing sheet 32 is connected to the upper end of the end cap side wall 31 and serves as the top plate of the upper end cap 3. The elastic sealing sheet 32 and the end cap side wall 31 are integrally formed, which can be integral injection molding or integral vulcanization molding, and the connection structure is stable.
[0059] In one embodiment, such as Figure 4-8 As shown, the inlet end 13 has an upward-opening pipe wall slot 131, and the end cap side wall 31 is inserted into the pipe wall slot 131.
[0060] In this embodiment, an annular pipe wall slot 131 is provided on the pipe wall of the inlet end 13, with the opening of the pipe wall slot 131 facing upward. During assembly, the cylindrical end cap sidewall 31 is inserted into the pipe wall slot 131, which facilitates the assembly of the upper end cap 3 onto the inlet end 13 of the sewage bend 1.
[0061] Preferably, the outer diameter of the inlet end 13 is larger than the outer diameter of the main body of the drain bend 1. The inlet end 13 is thicker and the pipe wall is thicker to form a pipe wall slot 131. At the same time, the two sides of the slot wall 131 have a certain thickness to improve the clamping force of the slot wall clamping end cap side wall 31.
[0062] In one embodiment, such as Figure 4-8 As shown, the surface of the end cap sidewall 31 is provided with a raised lip 311, which is squeezed and fitted with the groove wall of the tube wall slot 131.
[0063] In this embodiment, a raised lip 311 is integrally formed on the inner or outer surface of the end cap sidewall 31, and the raised lip 311 is annular. In the radial direction, the sum of the length of the raised lip 311 and the thickness of the end cap sidewall 31 is greater than the width of the tube wall slot 131. After the end cap sidewall 31 is inserted into the tube wall slot 131, the end of the raised lip 311 deforms to press against the wall of the tube wall slot 131, improving the stability of the end cap sidewall 31 assembled in the tube wall slot 131.
[0064] Preferably, multiple raised lips 311 are provided at intervals on the surface of the end cap sidewall 31 to further improve the stability of the end cap sidewall 31 when assembled in the tube wall slot 131.
[0065] In one embodiment, such as Figure 1-5 As shown, the sewage bend 1 includes a vertically extending second connecting pipe 12, an inlet end 13 located at the upper end of the second connecting pipe 12, one end of a U-shaped bend 11 connected to the lower end of the second connecting pipe 12, and the other end of the U-shaped bend 11 located on one side of the second connecting pipe 12.
[0066] In this embodiment, the drain bend 1 consists of a U-shaped bend 11 and a second connecting pipe 12. The second connecting pipe 12 is a vertical pipe. The second connecting pipe 12 is connected to one end (the first end) of the U-shaped bend 11 and extends upward. The inlet end 13 is located at the upper end of the second connecting pipe 12 to cooperate with the first connecting pipe 2. The other end (the second end) of the U-shaped bend 11 is slightly higher than one end (the first end) of the U-shaped bend 11 and is located on one side of the second connecting pipe 12. The other end (the second end) of the U-shaped bend 11 can be the outlet end 14 of the drain bend 1, or it can be used to connect with an intermediate transition pipe. Since the other end (the second end) of the U-shaped bend 11 is higher than one end (the first end) of the U-shaped bend 11, and one end (the first end) of the U-shaped bend 11 is the inlet end and the other end (the second end) of the U-shaped bend 11 is the outlet end, the water seal liquid level in the drain bend 1 can reach the second connecting pipe 12, thus improving the water seal effect.
[0067] In one embodiment, the second connecting pipe 12 and the U-shaped bend 11 are integrally formed. The two can be integrally injection molded, which has high structural strength, reduces the number of parts, and facilitates assembly.
[0068] like Figure 9-11 As shown, an embodiment of the present invention provides a urinal drain pipe mechanism, including a wall sleeve 4, a third connecting pipe 5 that is adjustablely passed through the wall sleeve 4 and is used to connect to the building's drain pipe, and the urinal drain pipe assembly described in any of the preceding embodiments.
[0069] One end of the third connecting pipe 5 is connected to the outlet end 14 of the sewage bend 1, and the third connecting pipe 5 is locked to the wall sleeve 4 by the locking element 6.
[0070] The urinal drain pipe mechanism provided by this utility model includes the aforementioned urinal drain pipe assembly, as well as a wall sleeve 4, a third connecting pipe 5, and a locking element 6.
[0071] Wall sleeve 4 is used for installation Figure 14-15 and Figure 16The wall panel 7 shown has an installation through hole 71. The third connecting pipe 5 can be a straight pipe or a bent pipe with an elbow at one end. One end of the third connecting pipe 5 is connected to the outlet end 14 of the drain bend 1, and the other end of the third connecting pipe 5 passes through the wall sleeve 4 to connect to the building's sewage pipe inside the wall. During on-site assembly, the depth or size of the third connecting pipe 5 passing through the wall sleeve 4 can be adjusted to accommodate the horizontal distance between the drain bend 1, the drain outlet 82, and the wall panel 7, facilitating on-site assembly. After adjustment, the third connecting pipe 5 is locked to the wall sleeve 4 using the locking element 6.
[0072] The locking element 6 can be a clamp, a lock nut, or the like.
[0073] In one embodiment, the end of the wall-mounted sleeve 4 facing the urinal 8 has a second external thread 41. The locking element 6 includes a second nut 61 and a conical washer 62 disposed in the second nut 61. The second nut 61 is fitted onto the end of the wall-mounted sleeve 4 and engages with the second external thread 41. The conical washer 62 is fitted onto the third connecting pipe 5. When the second nut 61 is tightened, the conical washer 62 is forced between the wall-mounted sleeve 4 and the third connecting pipe 5, providing a seal.
[0074] In one embodiment, such as Figure 9-11 As shown, the third connecting pipe 5 includes a horizontally extending connecting pipe main 51 and a connecting pipe elbow 52 integrally disposed at one end of the connecting pipe main 51 and extending downward.
[0075] The connecting pipe elbow 52 is connected to the outlet end 14, and the connecting pipe main pipe 51 passes through the wall sleeve 4 and is locked to the wall sleeve 4 by the locking element 6.
[0076] In this embodiment, one end of the third connecting pipe 5 is equipped with an elbow for connecting to the upward-facing outlet end 14. Specifically, the third connecting pipe 5 consists of a main connecting pipe 51 and a connecting pipe elbow 52. The main connecting pipe 51 is a straight pipe that extends horizontally, and the connecting pipe elbow 52 is integrally formed on the end of the main connecting pipe 51 facing the urinal 8. The connecting pipe elbow 52 bends downward and extends to connect to the outlet end 14. The connecting pipe elbow 52 and the outlet end 14 can be connected by insertion, welding, or other methods.
[0077] The main connecting pipe 51 passes through the wall sleeve 4 and is then locked to the wall sleeve 4 by the locking element 6. The main connecting pipe 51 is inserted into one end of the back side of the wall panel 7 for connection with the building's sewage pipe.
[0078] In this embodiment, the connecting pipe elbow 52 and the connecting pipe main pipe 51 can be integrally injection molded, which has high structural strength, reduces the number of parts, and facilitates assembly.
[0079] In one embodiment, such as Figure 5 and Figure 12-13 As shown, the top surface of the pipe wall at the outlet end 14 is provided with an annular first welding boss 141, and the bottom surface of the pipe wall at the connecting pipe elbow 52 is provided with an annular second welding boss 521.
[0080] The second welding boss 521 is welded to the first welding boss 141.
[0081] In this embodiment, to enable welding of the connecting pipe elbow 52 to the outlet end 14, a first welding boss 141, which is annular, is provided on the top surface of the outlet end 14. Before welding, the first welding boss 141 protrudes from the top surface of the outlet end 14. A second welding boss 521, which is annular, is provided on the bottom surface of the connecting pipe elbow 52. Before welding, the second welding boss 521 protrudes from the bottom surface of the connecting pipe elbow 52.
[0082] During welding, the second welding boss 521 is welded and fused together with the first welding boss 141. The distance between the second welding boss 521 and the first welding boss 141 gradually shortens, and the bottom surface of the connecting pipe elbow 52 falls on the top surface of the outlet end 14, so that there are no openings or gaps around the weld. In this way, the connecting pipe elbow 52 and the outlet end 14 are welded together.
[0083] The annular second welding boss 521 is welded to the annular first welding boss 141, resulting in a large welding connection area, which can improve the stability of the welding connection.
[0084] The urinal drain pipe mechanism provided by this utility model has a main body consisting of a drain pipe 1 including a U-shaped bend 11 and a second connecting pipe 12, and a third connecting pipe 5 including a main connecting pipe 51 and a connecting pipe elbow 52. The U-shaped bend 11 and the second connecting pipe 12 are integrally set, and the main connecting pipe 51 and the connecting pipe elbow 52 are integrally set, which greatly reduces the number of parts.
[0085] like Figure 14-16 As shown, an embodiment of the present invention provides a urinal device, including a wall panel 7 having a mounting through hole 71, a urinal 8 detachably mounted on the wall panel 7, and a urinal drain pipe mechanism as described in any of the preceding embodiments.
[0086] One end of the wall sleeve 4 is installed in the mounting through hole 71, and the other end of the wall sleeve 4 is located in the groove 83 on the back side of the urinal 8. The upper end of the first connecting pipe 2 is connected to the drain outlet 82 of the urinal 8, and the third connecting pipe 5 passes through the wall sleeve 4 and the mounting through hole 71.
[0087] The urinal device provided by this utility model includes the aforementioned urinal drain pipe mechanism, wall panel 7, and urinal 8.
[0088] The wall panel 7 is part of the wall, and it has an installation through hole 71 at the interface position of the building's sewage pipe for installing the wall sleeve 4 and for the third connecting pipe 5 to pass through and connect to the interface of the building's sewage pipe.
[0089] The urinal 8 is generally made of ceramic, with a urinal trough 81 on the front side and a drain outlet 82 at the bottom of the urinal trough 81. The back side of the urinal 8 has a back groove 83, which serves to reduce weight and also to house the fixtures.
[0090] The back of the urinal 8 is detachably connected to the wall panel 7. The two can be connected by pins, by a support structure, or by a hanging structure.
[0091] During assembly, one end of the wall sleeve 4 is fixedly installed in the mounting through hole 71, and the other end is located in the back groove 83. The upper end of the first connecting pipe 2 is connected to the drain outlet 82 of the urinal 8, and the third connecting pipe 5 passes through the wall sleeve 4 and the mounting through hole 71 to connect to the interface of the building's sewage pipe.
[0092] The urinal device provided by this utility model has a drain pipe 1 that is adjustable vertically. The lower end of the first connecting pipe 2 can be automatically inserted into the inlet end 13 of the drain pipe 1 to a certain depth as the urinal 8 falls, so as to adapt to the height of the drain outlet 82 from the ground, thus eliminating the need to cut the drain pipe 1 on site. The third connecting pipe 5 is adjustable horizontally to adapt to the distance between the urinal 8 and the wall panel 7, which is convenient for on-site assembly.
[0093] In one embodiment, such as Figure 15-16 As shown, the wall panel 7 is provided with a hook 72, and the back side groove 83 is provided with a corresponding hanging protrusion 84. When the back side of the urinal 8 is attached to the wall panel 7, the end of the hook 72 is hooked into the bottom groove of the hanging protrusion 84 to install the urinal 8 onto the wall panel 7.
[0094] The installation sequence for urinal 8 is as follows:
[0095] Step 1: Connect the wall sleeve 4 to the mounting through hole 71 of the wall panel 7.
[0096] Step 2: Pass one end of the third connecting pipe 5 through the wall sleeve 4 and the installation through hole 71, and connect it to the interface of the building's sewage pipe. Depending on the site conditions, the excess portion of the third connecting pipe 5 can be cut off.
[0097] Step 3: Axially adjust the third connecting pipe 5 to adjust the distance between the inlet end 13 of the drain bend 1 and the wall panel 7, thereby adapting to the distance between the drain outlet 82 and the wall panel 7. Then, lock the third connecting pipe 5 using the locking element 6.
