Technical Field

[0001] The utility model relates to a field, in particular to a shunt water seal trap device. Background Technique

[0002] The drainage system can play a role in draining in life, so it is an essential part of people's domestic water. In the prior art, a water seal trap is usually designed in the drainage system, and its main purpose is to prevent the sewer from emitting odors, flying insects, and virus transmission, and a water seal structure is formed through the water seal trap.

[0003] For example, the publication number "CN210421338U" discloses "a drain pipe with a water seal trap". The drain pipe includes a first connecting pipe connected to the water outlet of the drainage source. A water seal trap pipe is arranged at the end of the first connecting pipe. The other end of the water seal trap pipe is connected to a second connecting pipe. The water outlet of the second connecting pipe is connected to the sewage main pipe, and the first connecting pipe, the water seal trap pipe, and the second connecting pipe are integrally formed. However, in actual application, the setting of this type of water seal trap has a slow drainage volume, cannot achieve rapid drainage, and has a low error tolerance. After being blocked, it cannot drain water and requires immediate repair. Summary of the Invention

[0004] Aiming at the problems of slow drainage volume and low error tolerance existing in the prior art mentioned in the background technique, the utility model provides a shunt water seal trap device, which has more drainage channels, can achieve rapid drainage, improve drainage efficiency, and at the same time sets multiple drainage paths. The redundant setting can ensure smooth drainage in the case of a single-channel blockage and improve the error tolerance.

[0005] To achieve the above object, the utility model adopts the following technical solutions.

[0006] A shunt water seal trap device includes a water seal trap box body. A drainage pipe is arranged in the water seal trap box body. The drainage pipe includes a water inlet, and the water inlet is communicated with a water inlet cavity. A plurality of shunt channels are communicated on the side of the water inlet cavity far from the water inlet. A bending part is formed at the junction of each shunt channel and the water inlet cavity. In this application, a drainage pipe is arranged in the water seal trap box body. The drainage pipe includes a water inlet cavity and shunt channels. The water inlet cavity is communicated with each shunt channel. Through the shunt channels, the water entering the water inlet cavity can be divided into multiple paths for transportation, so as to improve the drainage efficiency. At the same time, when one of the shunt channels is blocked, the user can still drain water through the remaining shunt channels, so as to ensure the basic drainage effect in the case of internal blockage. At the same time, because one or more of the shunt channels are blocked and the drainage effect slows down, the user can know through the feedback during use, so as to carry out maintenance and cleaning in time. And during this process, the basic drainage effect can still be ensured, and the water seal effect is ensured through the bending part.

[0007] Preferably, each of the diversion channels is symmetrically arranged around the water inlet chamber. By arranging the diversion channels symmetrically, the uniformity of drainage can be ensured. Due to the symmetrical arrangement of the diversion channels, the entire device is symmetrically arranged, which can facilitate processing and production, improve the assembly and transportation efficiency, and enhance stability.

[0008] Preferably, the diversion channel includes a return bend area, the drainage pipe includes a water outlet pipe, and each of the diversion channels is connected to the water outlet pipe. The diversion channel realizes the water flow back through the return bend area, enters the water outlet pipe after passing through the return bend area, and the water outlet pipe is connected to each diversion channel, and each diversion channel converges at the water outlet pipe.

[0009] Preferably, the trap box body includes a central outer plate and a side outer plate, the side outer plate is arranged on the side of the central outer plate, an installation plate is arranged between the central outer plate and the side outer plate, and installation holes are arranged on the installation plate. The trap box body is provided with a central outer plate and a side outer plate, and the side outer plate is adjacent to the central outer plate. An installation plate is designed between the central outer plate and the side outer plate, and installation holes are arranged on the installation plate. The installation holes can fix the trap box body inside the wall through connecting pieces, so as to ensure the stable fixing effect of the trap.

[0010] Preferably, the water inlet chamber has a narrowed structure along the side of the water inlet towards the bending part. Designing the water inlet chamber into a narrowed structure can enable the position of the water inlet chamber close to the water inlet to be connected to the existing large-size water pipe, while the position of the water inlet chamber far from the water inlet is narrowed, so as to control the overall size.

[0011] Preferably, the center of the water inlet and the center of the bending part are vertically aligned along the gravity direction. Vertically aligning the center of the water inlet and the center of the bending part can ensure the assembly accuracy.

[0012] Preferably, a maintenance pipe is connected to the side of the bending part close to the wall surface, and a cover is detachably connected to one end of the maintenance pipe far from the bending part. A maintenance pipe is connected to the bending part, and a cover is connected to the maintenance pipe. By detachably connecting the cover to the maintenance pipe, the rapid cleaning effect of the impurities inside the bending part can be realized, avoiding the problem of inability to clean the internal impurities caused by the concealed drainage pipe, and the maintenance pipe is arranged towards the wall surface side, enabling the staff to better observe the situation inside the bending part.

[0013] Preferably, the cover includes a rotating outer ring, and a plurality of anti-slip protrusions are arranged on the rotating outer ring, and concave grooves are formed between the anti-slip protrusions. The anti-slip protrusions and concave grooves arranged on the cover can reduce the risk of slipping during the process of rotating and disassembling and installing the cover, and improve the assembly efficiency.

[0014] Preferably, a plugging rod is connected to one side of the cover close to the bending part. A sealing member is arranged on one side of the plugging rod close to the bending part, and the sealing member abuts against the inside of the maintenance pipeline. The plugging rod can block the channel from the bending part to the maintenance pipeline, so as to ensure that the water flow here can flow through the bending part and then along the diversion channel to the water outlet pipe, avoiding the chaotic flow direction at the bending part and reducing the risk of impurity accumulation.

[0015] Preferably, the water seal trap box body has a flat box body structure, and the water seal trap box body includes a bottom box, and a cover body is connected to the bottom box. The flat box body structure can reduce the grooving depth to the greatest extent, facilitate transportation, and the water seal trap box body is set as a split bottom box and cover body structure, which is convenient for processing.

[0029] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Embodiment 1:

[0031] As Figure 1 , 2 shown, a shunt trap device includes a trap box body 1, a drainage pipeline 2 is arranged in the trap box body 1, the drainage pipeline 2 includes a water inlet 21, the water inlet 21 is communicated with a water inlet cavity 22, a plurality of shunt channels 23 are communicated with the side of the water inlet cavity 22 far away from the water inlet 21, and a bending part 24 is formed at the junction of each shunt channel 23 and the water inlet cavity 22. In this application, the drainage pipeline 2 is arranged in the trap box body 1, the drainage pipeline 2 includes a water inlet cavity 22 and shunt channels 23, wherein the water inlet cavity 22 is communicated with each shunt channel 23, and the water entering the water inlet cavity 22 can be divided into multiple paths for transportation through the shunt channels 23, so as to improve the drainage efficiency. At the same time, when one of the shunt channels 23 is blocked, the user can still drain water through the remaining shunt channels 23, so as to ensure the basic drainage effect in the case of internal blockage. At the same time, because one or more of the shunt channels 23 are blocked, the drainage effect slows down, and the user can know through the feedback during use, so as to carry out maintenance and cleaning in time, and still ensure the basic drainage effect during this process, and ensure the water seal effect through the bending part 24.

[0032] As Figure 1 shown, each shunt channel 23 is symmetrically arranged with the water inlet cavity 22 as the center. The shunt channels 23 are symmetrically arranged, so as to ensure the drainage uniformity. Due to the symmetrical arrangement of the shunt channels 23, the whole device is symmetrically arranged, which can facilitate processing and production, improve the assembly and transportation efficiency, and improve the stability.

[0033] As Figure 1 shown, the shunt channel 23 includes a return bend area 25, the drainage pipeline 2 includes a water outlet pipe 26, and each shunt channel 23 is communicated with the water outlet pipe 26. The shunt channel 23 realizes the water flow return through the return bend area 25, enters the water outlet pipe 26 after passing through the return bend area 25, and the water outlet pipe 26 is communicated with each shunt channel 23, and each shunt channel 23 converges at the water outlet pipe 26.

[0034] As Figure 1As shown, the trap box body 1 includes a central outer plate 11 and side outer plates 12. The side outer plates are arranged on the sides of the central outer plate 11. An installation plate 13 is provided between the central outer plate 11 and the side outer plates 12, and installation holes 14 are provided on the installation plate 13. The trap box body 1 is provided with a central outer plate 11 and side outer plates 12, where the side outer plates 12 are adjacent to the central outer plate 11. An installation plate 13 is designed between the central outer plate 11 and the side outer plates 12, and installation holes 14 are provided on the installation plate 13. The installation holes 14 can fix the trap box body 1 inside the wall through connecting pieces, thus ensuring the stable fixing effect of the trap.

[0035] As Figure 1 shown, the water inlet cavity 22 is of a narrowing structure along the side of the water inlet 21 towards the bending part 24. Designing the water inlet cavity 22 into a narrowing structure enables the position of the water inlet cavity 22 near the water inlet 21 to be connected to an existing large-diameter water pipe, while the position of the water inlet cavity 22 far from the water inlet 21 is narrowed, thereby controlling the overall size.

[0036] As Figure 1 shown, the center of the water inlet 21 and the center of the bending part 24 are vertically aligned along the gravity direction. Vertically aligning the center of the water inlet 21 and the center of the bending part 24 can ensure the assembly accuracy.

[0037] The assembly and working process of a flow-dividing trap device in this embodiment are as follows: In this embodiment, a drainage pipe 2 is arranged inside the trap box body 1. The drainage pipe 2 is of a symmetrical structure as a whole. The drainage pipe 2 includes a water inlet cavity 22 connected to the water inlet 21. The water inlet cavity 22 extends vertically downward. Further, in this embodiment, the size of the water inlet cavity 22 near the water inlet 21 is larger, while the size of the water inlet cavity 22 far from the water inlet 21 is smaller. Therefore, during use, the area near the upper part of the water inlet cavity 22 connected to the water inlet 21 can be adaptively connected to the original pipe, and the narrowing of the area where the water inlet cavity 22 extends downward can ensure that the overall size will not be too large, improving the compactness. Further, the water inlet cavity 22 extends downward to the bottom position and is connected to a plurality of flow-dividing channels 23. In this embodiment, there are two flow-dividing channels 23, which are respectively arranged on the left and right sides of the water inlet cavity 22. The two flow-dividing channels 23 are respectively connected to the water inlet cavity 22. Therefore, in this embodiment, two bending parts 24 are formed at the bottom of the water inlet cavity 22, and a water seal will be formed when the water drains here, thus avoiding problems such as odor backflow and flying insects. Further, the water flowing into the water inlet cavity 22 from the water inlet 21 will be divided here and discharged to the outlet pipe 26 along the flow-dividing channels 23 on the left and right sides respectively, and each flow-dividing channel 23 converges at the outlet pipe 26.

[0038] In this embodiment, since there are multiple diversion channels 23 provided, the water entering the water inlet chamber 22 can be discharged into the water outlet pipe 26 through different diversion channels 23. When the cross-sectional areas of the water inlet 21 and the water outlet pipe 26 are the same, setting multiple diversion channels 23 can improve the drainage efficiency of the water flow here, thus ensuring the drainage efficiency. Further, in daily domestic water use, since impurities may flow in with the water flow, due to the presence of the bending part 24, the impurities are likely to accumulate at the bending part 24. If only a single channel is provided between the water inlet chamber 22 and the water outlet pipe 26, if a blockage occurs, it will cause poor drainage of the entire drainage pipe. In this embodiment, the diversion channels 23 provide multiple water outlet paths and bending parts. On the basis of ensuring that a water seal can be formed, since the water flow can flow to the water outlet pipe 26 through different diversion channels 23, even if there is a foreign object blockage in a certain diversion channel 23, the water entering the water inlet chamber 22 can still be conveyed through the remaining diversion channels 23. The main change is that the drainage speed is affected, rather than directly resulting in no drainage. Therefore, since the drainage speed is affected, the user can notice it during use and can make preparations for maintenance earlier. At the same time, it can also ensure the normal use requirements of the user to a certain extent, avoiding the situation where when using a single-channel drainage, it is directly blocked and the user cannot use it before preparing for maintenance. Through this setting method, the redundancy of drainage can be improved, providing a certain basic guarantee effect for the normal domestic water use of the user.

[0039] In this embodiment, the water seal trap box body 1 includes a central outer plate 11. An inlet chamber 22 is formed inside the central outer plate 11. Side outer plates 12 are respectively designed on both sides of the central outer plate 11. A diversion channel 23 is formed inside the side outer plate 12. In this embodiment, a mounting plate 13 is provided between the central outer plate 11 and the side outer plates 12. Mounting holes 14 are provided on the mounting plate 13. The mounting holes 14 can fix this device inside the wall through fixing parts such as connecting expansion screws. And mounting plates 13 are provided between the central outer plate 11 and the left and right side outer plates 12 respectively, so as to ensure the uniform fixation of this device. Further, since the drainage pipes 2 of this device are also symmetrically arranged, under normal circumstances, the water flow is also evenly flowing, ensuring stability during the working process. At the same time, the symmetrical setting is more convenient for installation and transportation, more beautiful, and has a better connection effect. And for the water seal trap box body 1 with multiple diversion channels 23, the required grooving length during the grooving process is less than that of the single-channel water seal trap box body 1, so the workload is reduced and the installation efficiency is improved.

[0040] Embodiment 2:

[0041] As Figure 3As shown, different from Embodiment 1, in this embodiment, a maintenance pipeline 3 is connected to the side of the bending part 24 close to the wall surface, and a cover 31 is detachably connected to one end of the maintenance pipeline 3 away from the bending part 24. A maintenance pipeline 3 is communicated with the bending part 24, and a cover 31 is connected to the maintenance pipeline 3. The cover 31 is detachably connected to the maintenance pipeline 3, so as to achieve the effect of quickly cleaning the impurities inside the bending part 24, avoiding the problem that the internal impurities cannot be cleaned due to the concealed drainage pipeline, and the maintenance pipeline 3 is arranged towards the wall surface side, enabling the staff to better observe the situation inside the bending part 24.

[0042] As Figure 4 shown, the cover 31 includes a rotating outer ring, and a plurality of anti-slip protrusions 32 are arranged on the rotating outer ring, and a concave groove 33 is formed between the anti-slip protrusions 32. The anti-slip protrusions 32 and the concave grooves 33 arranged on the cover 31 can reduce the risk of slipping during the process of rotating and disassembling and installing the cover 31, and improve the assembly efficiency.

[0043] As Figure 3 shown, a plugging rod 34 is connected to the side of the cover 31 close to the bending part, and a sealing member 35 is arranged on the side of the plugging rod 34 close to the bending part, and the sealing member 35 abuts against the inside of the maintenance pipeline 3. The channel from the bending part 24 to the maintenance pipeline 3 can be blocked by the plugging rod 34, so as to ensure that the water flow here can flow through the bending part 24 and then flow into the water outlet pipe 26 along the diversion channel 23, avoiding the chaotic flow direction at the bending part 24 and reducing the risk of impurity accumulation.

[0044] As Figure 3 shown, the water seal trap box body 1 has a flat box body structure, and the water seal trap box body 1 includes a bottom box 15, and a cover body 16 is connected to the bottom box 15. The flat box body structure can reduce the grooving depth to the greatest extent, and is convenient for transportation. And the water seal trap box body 1 is set as a split structure of the bottom box 15 and the cover body 16, which is convenient for processing.

[0045] In this embodiment, the assembly and working process of a shunt trap device are as follows: In this embodiment, the trap box body 1 is divided into a bottom box 15 and a cover body 16, where the bottom box 15 and the cover body 16 are separately arranged. Various plate components are provided on the bottom box 15, so that a drainage pipeline 2 is formed after the bottom box 15 and the cover body 16 are connected. An inspection pipeline 3 is also connected to the cover body 16. The inspection pipeline 3 is arranged on the side of the cover body 16 away from the bottom box 15 and is disposed opposite to the bending part 24. Therefore, the impurities inside the bending part 24 can be cleaned through the inspection pipeline 3. When the inspection pipeline 3 is installed, it needs to penetrate the wall and extend to the outside, and the inspection pipeline 3 is connected with a sealing cover 31. The staff can remove the sealing cover 31 from the inspection pipeline 3 on the outside of the wall, so that tools can be used through the inspection pipeline 3 to clean the impurities on the bending part 24. Since the inspection pipeline 3 is arranged in the forward position of the cover body 16, the staff can directly visually observe the impurities on the bending part 24 through the inspection pipeline 3, which is convenient for cleaning. At the same time, in this embodiment, a plugging rod 34 is connected to the sealing cover 31. The plugging rod 34 is arranged on the side of the sealing cover 31 close to the bending part 24, and the plugging rod 34 can block the water flow from the bending part 24 to the inspection pipeline 3. A sealing member 35 is arranged on the plugging rod 34 to increase the sealing effect through the sealing member 35.

[0046] Furthermore, the inspection pipeline 3 and the sealing cover 31 in this embodiment are threadedly connected. The threaded connection ensures the connection sealing performance of the sealing cover 31 and can form an effective extrusion sealing effect on the sealing member 35. Therefore, for subsequent maintenance, it is convenient for disassembly and assembly. Therefore, anti-slip protrusions 32 and corresponding concave grooves 33 are provided on the sealing cover 31. The anti-slip protrusions 32 and the concave grooves 33 are arranged in a staggered manner, and a plurality of anti-slip protrusions 32 and concave grooves 33 are provided. This can avoid the phenomenon of slipping during the process of rotating the sealing cover 31.

[0047] In this embodiment, a drain pipe 2 is provided inside the trap box body 1. The drain pipe 2 is of a symmetrical structure as a whole. The drain pipe 2 includes an inlet chamber 22 connected to the water inlet 21. The inlet chamber 22 extends vertically downward. Further, in this embodiment, the dimension of the inlet chamber 22 near the water inlet 21 is larger, while the dimension of the inlet chamber 22 far from the water inlet 21 is smaller. Therefore, in the process of use, the area near the upper part of the inlet chamber 22 connected to the water inlet 21 can be adapted to connect the original pipe, and the narrowing of the area where the inlet chamber 22 extends downward can ensure that the overall dimension will not be too large, improving the compactness. Further, the inlet chamber 22 extends downward to the bottom position and communicates with a plurality of diversion channels 23. In this embodiment, two diversion channels 23 are provided, which are respectively arranged on the left and right sides of the inlet chamber 22. The two diversion channels 23 are respectively communicated with the inlet chamber 22. Therefore, in this embodiment, two bending parts 24 are formed at the bottom of the inlet chamber 22, and a water seal will be formed when the water drains here, thus avoiding problems such as odor backflow and flying insects. Further, the water flowing into the inlet chamber 22 from the water inlet 21 will be diverted here and discharged to the outlet pipe 26 along the diversion channels 23 on the left and right sides respectively. Each diversion channel 23 converges at the outlet pipe 26.

[0048] In this embodiment, due to the provision of multiple diversion channels 23, the water flowing into the inlet chamber 22 can be discharged into the outlet pipe 26 through different diversion channels 23. When the cross-sectional areas of the water inlet 21 and the outlet pipe 26 are the same, setting multiple diversion channels 23 can improve the drainage efficiency of the water flow here, thus ensuring the drainage efficiency. Further, in daily domestic water use, since impurities may flow in with the water flow, due to the existence of the bending part 24, the impurities are likely to accumulate at the bending part 24. If only a single channel is provided between the inlet chamber 22 and the outlet pipe 26, if a blockage occurs, it will cause poor drainage of the entire drain pipe. However, in this embodiment, the diversion channels 23 provide multiple water discharge paths and bending parts. On the basis of ensuring that a water seal can be formed, since the water flow can flow to the outlet pipe 26 through different diversion channels 23, even if a foreign object blocks one of the diversion channels 23, the water flowing into the inlet chamber 22 can still be conveyed through the remaining diversion channels 23. The main change is that the drainage speed is affected, rather than directly resulting in no drainage. Therefore, since the drainage speed is affected, the user can detect it during the use process and can make preparations for maintenance earlier. At the same time, it can also ensure the normal use requirements of the user to a certain extent, avoiding the situation where when using a single-channel drainage, it is directly blocked and the user cannot use it until after preparing for maintenance. Through this setting method, the redundancy of drainage can be improved, providing a certain basic guarantee effect for the normal domestic water use of the user.

[0049] In this embodiment, the water seal box body 1 includes a central outer plate 11. An inlet cavity 22 is formed inside the central outer plate 11. Side outer plates 12 are respectively designed on both sides of the central outer plate 11. A diversion channel 23 is formed inside the side outer plates 12. In this embodiment, a mounting plate 13 is arranged between the central outer plate 11 and the side outer plates 12. Mounting holes 14 are arranged on the mounting plate 13. The mounting holes 14 can fix the device inside the wall through fixing parts such as connecting expansion screws. And mounting plates 13 are arranged between the central outer plate 11 and the side outer plates 12 on the left and right sides respectively, so as to ensure the uniform fixation of the device. Further, since the drain pipe 2 of the device is also symmetrically arranged, under normal circumstances, the water flow is also uniform, ensuring the stability during the working process. At the same time, the symmetrical setting is more convenient for installation and transportation, more beautiful, and has a better connection effect. And for the water seal box body 1 provided with multiple diversion channels 23, the required grooving length during the grooving process is less than that of the single-channel water seal box body 1, so the workload is reduced and the installation efficiency is improved.
