Description

Technical Field

[0001] The utility model relates to the technical field of sewer assemblies, in particular to an anti-overflow and anti-odor sewer assembly. Background Art

[0002] The anti-overflow and anti-odor sewer assembly for a sink (kitchen sink) and a washbasin (washbowl) is a fitting specially designed to connect a sink or a washbasin to a sewage system.

[0003] Currently, the patent with the publication number CN218374221U discloses a sink sewer pipe for preventing foam overflow, which includes a sewage pipe, a sewage main body, and an overflow pipe. The sewage main body is detachably installed at the water outlet end of the sewage pipe, and the overflow pipe is detachably installed on the sewage main body. An interface for connecting with the overflow pipe is provided on the side of the sewage main body. The diameter of the position around the interface in the sewage main body decreases along the water flow direction. Specifically, an anti-overflow structure is adopted. An anti-overflow structure is provided in the sewage main body. A through hole communicating with the interface is provided on the side of the anti-overflow structure, and the diameter around the through hole decreases along the water flow direction. A water curtain is formed when the water flow passes through this through hole, which can effectively prevent foam from overflowing from the overflow pipe. And it also includes a water seal main body, a water seal cover, and a drainage pipe. The water seal main body is connected with the water seal cover, and a water seal is formed at the bottom of the water seal cover, which can effectively prevent odor and form a water path communicating with the drainage pipe to enable the water flow to be discharged smoothly, providing user comfort.

[0004] However, there are still the following problems in the current anti-overflow and anti-odor sewer assembly:

[0005] Most of the current anti-overflow and anti-odor sewer assemblies are a whole. The two ends of the pipe are respectively connected to the bottom of the sink or the washbasin, and the other end is connected to the sewer pipe, so that the water discharged from the sink or the washbasin can accurately enter the sewage pipe.

[0006] Currently, in order to prevent the odor in the sewage pipe from flowing back into the sink or the washbasin, a bent pipe section is often reserved during installation, and the water retained in the bent pipe section is used to prevent the gas from passing through. However, for the same bent pipe section, the impurities in the sewage discharged from the upper sink or washbasin are very likely to accumulate here, resulting in pipeline blockage over time. The current method is to remove the entire pipeline assembly to dredge the inside of the pipeline, but the pipeline is relatively long and it is very troublesome to clean, time-consuming and laborious. Utility Model Content

[0007] Aiming at the deficiencies of the prior art, the utility model provides an anti-overflow and anti-odor sewer assembly to achieve the purpose of quickly cleaning the blocked area.

[0008] The utility model provides the following technical solution: An anti-overflow and anti-odor sewer pipe assembly, which includes a water inlet pipe. The lower end of the water inlet pipe is fixedly connected and communicated with a spherical pipe. The other end of the spherical pipe is communicated with a bent pipe. The other end of the bent pipe is communicated with another spherical pipe. The other end of the other spherical pipe is fixedly connected and communicated with a water outlet pipe. Inner spheres are slidably connected to the inner walls of the two spherical pipes. A telescopic assembly is connected between the two inner spheres, and one end of the telescopic assembly is connected with two symmetrically arranged limiting assemblies.

[0009] Further, the telescopic assembly includes an outer rod and an inner rod. One end of the outer rod penetrates through the outer wall of one of the spherical pipes and is fixedly connected to the inner sphere inside this spherical pipe. A receiving cavity is opened at the other end of the outer rod. One end of the inner rod is located in the receiving cavity. The other end of the inner rod penetrates through the outer wall of the other spherical pipe and is fixedly connected to the inner sphere inside this spherical pipe. And the outer wall of the inner rod is slidably connected to the inner wall of the receiving cavity. Both limiting assemblies are connected to the outer rod and the inner rod.

[0010] Further, a plurality of sliding grooves are opened on the inner wall of the receiving cavity. A plurality of sliding blocks are fixedly connected to the outer wall of the end of the inner rod located in the receiving cavity. The outer walls of the plurality of sliding blocks are respectively slidably connected to the inner walls of the plurality of sliding grooves.

[0011] Further, a plurality of jacks are penetrated and opened on the outer wall of the inner rod. Both limiting assemblies are connected to the jacks.

[0012] Further, the limiting assembly includes a limiting tube and a plug rod. One end of the limiting tube is fixedly connected to one end of the outer rod close to the opening of the receiving cavity. One end of the plug rod penetrates through the limiting tube and the outer rod and is slidably connected to the inner wall of the jack.

[0013] Further, a spring cavity is opened inside the limiting tube. A top plate is sleeved and fixedly connected to the outer wall of the plug rod. The outer wall of the top plate is slidably connected to the inner wall of the spring cavity. The diameter of the top plate is larger than the diameter of the plug rod.

[0014] Further, an extrusion spring is fixedly connected to the side of the top plate away from the outer rod. The other end of the extrusion spring is fixedly connected to the inner wall of the other side of the spring cavity.

[0015] Further, a pull handle is fixedly connected to the end of the plug rod penetrating through the limiting tube.

[0016] Further, threaded pipes are fixedly connected and communicated to the ends of the two spherical pipes away from the water inlet pipe and the water outlet pipe. The inner walls of both ends of the bent pipe are respectively threadedly connected to the outer walls of the two threaded pipes.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] This kind of anti-overflow and anti-odor sewer pipe assembly is provided with a water inlet pipe, a bent pipe and a water outlet pipe, and two spherical pipes are arranged at the joints of the water inlet pipe and the water outlet pipe with the bent pipe. Then, a telescopic assembly is used for sealing. When the user uses the sewer pipe assembly, if an accident occurs at the bent pipe, the limiting assembly can drive the two inner spheres to partition and seal the inside of the spherical pipe, and then the bent pipe can be disassembled separately, so as to achieve the purpose of rapid cleaning.

Detailed Embodiment

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0026] Please refer to Figures 1-5 , a kind of anti-overflow and anti-odor sewer pipe assembly, including a water inlet pipe 1. The lower end of the water inlet pipe 1 is fixedly connected and communicated with a spherical pipe 4. The other end of the spherical pipe 4 is communicated with a bent pipe 2. The other end of the bent pipe 2 is communicated with another spherical pipe 4. The other end of the other spherical pipe 4 is fixedly connected and communicated with a water outlet pipe 3. The inner walls of the two spherical pipes 4 are both slidably connected with inner spheres 10. A telescopic assembly is connected between the two inner spheres 10, and one end of the telescopic assembly is connected with two symmetrically arranged limiting assemblies.

[0027] A kind of anti-overflow and anti-odor sewer pipe assembly in the present utility model is similar in structure to the existing anti-overflow and anti-odor sewer pipe assembly, such as a sink sewer pipe for preventing foam overflow disclosed in the patent with the publication number CN218374221U. As Figures 1 to 5 shown, when the anti-overflow and anti-odor sewer pipe assembly in the present utility model is in use, first, the upper end of the water inlet pipe 1 is fixed to the drain pipe of the vegetable basin or washbasin (this is the prior art, and currently, most methods are by screwing tightly with threads), and then the lower end of the water outlet pipe 3 is connected to the pipe opening of the sewer (this is also the prior art). During use, if the sewage discharged from the inside of the vegetable basin or washbasin contains sundries (such as vegetable leaves, rice grains, etc.), when flowing from the drain pipe of the vegetable basin or washbasin into the water inlet pipe 1, because there is a bent pipe 2 between the water inlet pipe 1 and the water outlet pipe 3, when the water flow is small or the sundries are too large, these sundries are very likely to stay in the bent pipe 2, and over time, the inside of the bent pipe 2 will be blocked. When a blockage occurs, just manually rotate the telescopic assembly. After the telescopic assembly rotates, it can drive the two inner balls 10 located at both ends inside the ball pipe 4 to rotate. After the two inner balls 10 rotate, the water flow ports on the inner balls 10 can be separated and sealed from the water inlet pipe 1 and the water outlet pipe 3. Therefore, at this time, the bent pipe 2 is in a state where it is not internally connected to the water inlet pipe 1 and the water outlet pipe 3. Then, the bent pipe 2 is removed from the water inlet pipe 1 and the water outlet pipe 3, and the sundries originally blocked inside the bent pipe 2 will be removed together. After that, only the blocked sundries inside the bent pipe 2 need to be cleaned separately, which is convenient and time-saving.

[0028] It should be particularly noted here that:

[0029] 1. The water inlet pipe 1, the bent pipe 2, and the water outlet pipe 3 are all universal hoses.

[0030] 2. Because the distances between the vegetable basins or washbasins and the sewer pipes in each family are different, sometimes it is necessary to adjust the angle and extension length of the bent pipe 2. At this time, in order not to affect the normal adjustment of the bent pipe 2, the two limit components can be removed, and the telescopic assembly can be moved to increase the distance between the two ball pipes 4, so as to achieve the purpose of length adjustment.

[0031] 3. The rotation of the inner ball 10 inside the ball pipe 4 can be limited to only rotate 90°. In this way, when rotating the telescopic assembly, the water inlet pipe 1 and the water outlet pipe 3 can be accurately opened and closed through the inner ball 10; and rotating 90° is the prior art, such as the common way of a slider sliding in a slot that can only rotate 90°. Of course, other methods can also be used, and specific details are not limited.

[0032] Please mainly refer to Figures 1-5The telescopic assembly includes an outer rod 5 and an inner rod 6, one end of the outer rod 5 penetrates the outer wall of one of the ball tubes 4 and is fixedly connected to the inner ball 10 inside the ball tube 4, the other end of the outer rod 5 is provided with a storage cavity 501, one end of the inner rod 6 is located in the storage cavity 501, the other end of the inner rod 6 penetrates the outer wall of the other ball tube 4 and is fixedly connected to the inner ball 10 inside the ball tube 4, and the outer wall of the inner rod 6 is slidably connected to the inner wall of the storage cavity 501, and two limit assemblies are connected to the outer rod 5 and the inner rod 6.

[0033] More specifically, when it is necessary to cut off the water inlet pipe 1 and the water outlet pipe 3, it is only necessary to rotate the outer rod 5. After the outer rod 5 is rotated, the inner rod 6 can be driven to rotate. When the outer rod 5 and the inner rod 6 rotate, the two inner balls 10 inside the two ball tubes 4 will be driven to rotate at the same time, thereby completing the effect of cutting off the water inlet pipe 1 and the water outlet pipe 3.

[0034] When the distance between the two ball tubes 4 needs to be adjusted, it is only necessary to loosen the limit assembly. At this time, the inner rod 6 can be moved in the storage cavity 501 of the outer rod 5. When it is moved to a suitable distance, the inner rod 6 can be limited and fixed by the limit assembly. It is simple and easy to operate.

[0035] Please refer to Figure 5 The inner wall of the storage chamber 501 is provided with a plurality of slide grooves 502 , and the outer wall of one end of the inner rod 6 located in the storage chamber 501 is fixedly connected with a plurality of sliders 11 , and the outer walls of the plurality of sliders 11 are slidably connected with the inner walls of the plurality of slide grooves 502 .

[0036] More specifically, by providing the slide groove 502 and the slider 11 , firstly, it can be ensured that the inner rod 6 can only move in a specific direction when sliding; secondly, it can prevent the inner rod 6 from falling from the storage cavity 501 of the outer rod 5 .

[0037] Please refer to Figures 3-5 A plurality of insertion holes 601 are formed through the outer wall of the inner rod 6 , and both the two limit assemblies are connected to the insertion holes 601 .

[0038] More specifically, by providing the insertion hole 601, the connectivity between the limit assembly and the inner rod 6 can be increased, and due to the action of the slider 11 and the slide groove 502, the limit assembly and the insertion hole 601 can always be kept on the same horizontal line.

[0039] Please refer to Figures 3-5 The limiting assembly includes a limiting tube 7 and an insertion rod 13. One end of the limiting tube 7 is fixedly connected to one end of the outer rod 5 near the opening of the storage cavity 501. One end of the insertion rod 13 passes through the limiting tube 7 and the outer rod 5, and is slidably connected to the inner wall of the insertion hole 601.

[0040] More specifically, when it is necessary to limit the inner rod 6, only need to pull out the insertion rod 13 from the limiting tube 7 and the insertion hole 601. When the inner rod 6 moves to an appropriate length, then insert the insertion rod 13 into the insertion hole 601, which is convenient and fast.

[0041] Please mainly refer to Figures 3-5 , a spring cavity 701 is provided inside the limiting tube 7. The outer wall of the insertion rod 13 is sleeved and fixedly connected with a top plate 14. The outer wall of the top plate 14 is slidably connected with the inner wall of the spring cavity 701. The diameter of the top plate 14 is larger than that of the insertion rod 13.

[0042] More specifically, by providing the spring cavity 701 and the top plate 14, it is possible to prevent the insertion rod 13 from falling out of the inside of the limiting tube 7.

[0043] Please mainly refer to Figures 3-5 , a compression spring 12 is fixedly connected to the side of the top plate 14 away from the outer rod 5. The other end of the compression spring 12 is fixedly connected to the inner wall of the other side of the spring cavity 701.

[0044] More specifically, by providing the compression spring 12, after the insertion rod 13 is pulled out, when the insertion rod 13 is aligned with the insertion hole 601, just let go, and the insertion rod 13 can be automatically inserted into the insertion hole 601.

[0045] Please mainly refer to Figures 1-5 , a pull handle 8 is fixedly connected to the end of the insertion rod 13 passing through the limiting tube 7.

[0046] More specifically, by providing the pull handle 8, it is more convenient to grip when pulling the insertion rod 13.

[0047] Please mainly refer to Figure 2 and Figure 3 , both ends of the two spherical tubes 4 away from the water inlet pipe 1 and the water outlet pipe 3 are fixedly connected and communicated with a threaded pipe 9. The inner walls of both ends of the elbow pipe 2 are respectively threadedly connected with the outer walls of the two threaded pipes 9.

[0048] More specifically, by providing the threaded pipe 9, it is more convenient and labor-saving when it is necessary to disassemble the elbow pipe 2; it should be particularly noted here that: a sealing ring is provided at the connection between the threaded pipe 9 and the elbow pipe 2.
