Description

Technical Field

[0001] This utility model relates to the field of water drainage technology, and in particular to a riser water drainage device. Background Technology

[0002] Over time, bathrooms may experience water leakage into the drainage system's sump due to factors such as leaky drain pipe connections, damaged drain pipes, or surface water seeping through weak points like corners. This water can accumulate in the sump and eventually overflow, overflowing the threshold and seeping into other rooms. This can cause mold and blistering on adjacent walls, and even damage wooden floors. Therefore, a drain drainer is needed to remove the accumulated water.

[0003] Current riser drain systems, while not affecting normal drainage of the riser connection, also have a connecting hole for draining accumulated water. When there is water in the sump, the water will enter the riser through the connecting hole for drainage. However, the connecting hole cannot isolate odors from the drain pipe, causing odors to enter the sump through the connecting hole. These odors also contain various germs that can cause respiratory or intestinal diseases. Over time, the odors will spread into the bathroom, affecting the health of the users. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a riser water drainer. The riser has an odor-proof and sealing function, achieving the technical effect of preventing the spread of odors without affecting the drainage of accumulated water.

[0005] To solve the above-mentioned technical problems and achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution:

[0006] The technical solution of this utility model is: a riser water drainer, including a support cylinder, a drainage chamber is opened through the inside of the support cylinder, an upper connecting pipe is fixedly installed at the top of the drainage chamber, a lower connecting pipe is fixedly installed at the bottom of the drainage chamber, an upper flow hole inside the upper connecting pipe is connected to a lower flow hole inside the lower connecting pipe, and the drainage chamber is connected to the lower flow hole through the upper flow hole; a connecting ring is fixedly installed at the top of the outer wall of the upper connecting pipe, which contacts the inner wall of the support cylinder, and a drainage hole for draining accumulated water is opened at the top of the connecting ring, and the drainage hole is connected to the top of the drainage chamber; mounting seats are provided on both sides of the bottom of the outer wall of the support cylinder; the drainage chamber, the upper flow hole and the lower flow hole form a water seal structure;

[0007] When the water seal structure drains water, the accumulated water enters the drainage chamber through the drainage hole, and then flows through the bottom of the drainage chamber along the outer wall of the lower connecting pipe into the upper flow hole, and finally exits through the lower flow hole by gravity.

[0008] Furthermore, the diameter of the upper connecting pipe is larger than the diameter of the lower connecting pipe, and the bottom end of the upper connecting pipe extends downward to the outside of the lower connecting pipe.

[0009] Furthermore, a gap is left between the outer wall of the lower connecting pipe and the inner wall of the upper flow hole, and the drainage cavity is connected to the upper flow hole and the lower flow hole in sequence through the gap.

[0010] Furthermore, the inner wall of the upper connecting pipe is provided with a sealing ring to increase friction, and the interior of the sealing ring is provided with an air cavity for buffering deformation.

[0011] Furthermore, both ends of the two mounting bases are provided with threaded holes that can be used with screws.

[0012] Furthermore, a protective sleeve is fitted over the outer wall of the support cylinder, and a fixing plate is fixedly installed on the top of the outer wall of the protective sleeve.

[0013] Furthermore, multiple drainage holes are arranged around the upper connecting pipe.

[0014] Furthermore, a flow guide ring is fixedly installed on the inner wall of the upper connecting pipe and at the bottom of the sealing ring, and the diameter of the bottom of the flow guide ring is smaller than the diameter of the lower flow hole.

[0015] Furthermore, the outer wall of the connecting ring is provided with a connecting groove, and the inner wall of the support cylinder is fixedly installed with a locking block that matches the connecting groove. The connecting groove consists of an entry section, a translation section and an end section from bottom to top.

[0016] When installing the connecting ring, align the entry section at the bottom of the connecting groove with the locking block, then press the connecting ring down so that the locking block moves through the entry section to the translation section. At this time, rotate the connecting ring so that the locking block moves through the translation section into the end section. Finally, continue to move the connecting ring down so that the locking block enters the top of the end section.

[0017] The beneficial technical effects of this utility model are as follows: When the device is installed, when the water in the sump overflows the drain hole, it will flow into the interior of the drain chamber through the drain hole and enter the interior of the upper flow hole through the gap between the upper and lower connecting pipes. When the water overflows the lower connecting pipe, it will be discharged through the lower flow hole. The water below the bottom of the drain chamber will form a water seal at the bottom of the drain chamber, preventing odors in the drain pipe from entering the sump through the drain chamber and drain hole. This avoids the problem that odors can spread into the bathroom through the connecting hole because the connecting hole cannot isolate the odors in the drain pipe. Attached Figure Description

[0025] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0026] See appendix Figures 1-5As shown, a riser water drain includes a support cylinder 2, with a drainage chamber 3 extending through the inside of the support cylinder 2. An upper connecting pipe 1 is fixedly installed at the top of the drainage chamber 3, and a lower connecting pipe 7 is fixedly installed at the bottom of the drainage chamber 3. The lower connecting pipe 7 is connected to the drainage pipe in the caisson, and the surface of the upper connecting pipe 1 is parallel to the bottom of the caisson. Then, the upper drainage pipe is installed in the upper connecting pipe 1 to facilitate normal drainage.

[0027] The diameter of the upper connecting pipe 1 is larger than the diameter of the lower connecting pipe 7. The bottom end of the upper connecting pipe 1 extends downward to the outside of the lower connecting pipe 7. The upper flow hole 11 inside the upper connecting pipe 1 is connected to the lower flow hole 71 inside the lower connecting pipe 7. A gap is left between the outer wall of the lower connecting pipe 7 and the inner wall of the upper flow hole 11. The drainage chamber 3 is connected to the upper flow hole 11 and the lower flow hole 71 in sequence through the gap. The drainage chamber 3 is connected to the lower flow hole 71 through the upper flow hole 11. The top of the outer wall of the upper connecting pipe 1 is fixedly installed with the support cylinder 2. The connecting ring 4 is in contact with the wall. The top of the connecting ring 4 is provided with a drain hole 41 for draining accumulated water. The drain hole 41 is connected to the top of the drain cavity 3. Mounting seats 8 are provided on both sides of the bottom of the outer wall of the support cylinder 2. The drain cavity 3, the upper flow hole 11 and the lower flow hole 71 form a water seal structure. When the water seal structure drains, the accumulated water enters the interior of the drain cavity 3 through the drain hole 41, and then enters the upper flow hole 11 along the outer wall of the lower connecting pipe 7 through the bottom of the drain cavity 3. Finally, it is discharged into the lower flow hole 71 by gravity.

[0028] During the process of draining water from the sump, when the water enters the drainage chamber 3 through the drain hole 41 and then overflows the lower connecting pipe 7, it will be discharged through the lower flow hole 71. After discharge, some water will remain at the bottom of the drainage chamber 3, forming a water seal between the lower connecting pipe 7 and the upper connecting pipe 1 to prevent odors. When new water enters the drainage chamber 3 through the drain hole 41, the new water will push the old water into the lower flow hole 71 for discharge. The water below the bottom of the drainage chamber 3 will form a water seal at the bottom of the drainage chamber 3 to prevent odors from the drain pipe from entering the sump through the drainage chamber 3 and the drain hole 41, thus preventing odors from spreading into the bathroom through the connecting hole.

[0029] Furthermore, the inner wall of the upper connecting pipe 1 is provided with a sealing ring 6 to increase friction, and the inside of the sealing ring 6 is provided with an air cavity 61 for buffering deformation. The outer wall of the support cylinder 2 is fitted with a protective sleeve 5, and a fixing plate 51 is fixedly installed on the top of the outer wall of the protective sleeve 5. By setting the fixing plate 51, when the drainer is backfilled in the bathroom sump after installation, the fixing plate 51 makes it easy for the staff to level it, so as to prevent the drainage hole 41 from being too high due to the plane being too low during the backfilling process, which would affect the drainage of water accumulation in the sump.

[0030] By setting a sealing ring 6, when the upper drain pipe is inserted into the upper connecting pipe 1, the sealing ring 6 inside the upper connecting pipe 1 will contact the upper drain pipe to seal it. As the upper drain pipe continues to enter, when the sealing ring 6 is squeezed, the space of the air cavity 61 causes the sealing ring 6 to undergo slight deformation, so that the sealing ring 6 fits better against the surface of the upper drain pipe and seals the space between the upper connecting pipe 1 and the upper drain pipe.

[0031] Furthermore, both ends of the two mounting bases 8 are provided with threaded holes 81 that can be used with screws.

[0032] By setting the threaded hole 81, when the lower connecting pipe 7 is connected to the drainage pipe at the bottom of the caisson, the drainage pipe at the bottom of the caisson is sealed to the lower connecting pipe 7, and then bolts are used to fix it to the bottom of the caisson through the threaded hole 81.

[0033] Furthermore, multiple drainage holes 41 are arranged around the connecting pipe 1 above the drainage hole 41. The arrangement of multiple drainage holes 41 allows water to be discharged through diversion, while the drainage holes 41 can only allow objects that are the same size as their own holes to enter, thus preventing larger foreign objects from entering the drainage chamber 3 and causing blockage inside the drainage chamber 3.

[0034] Furthermore, a guide ring 12 is fixedly installed on the inner wall of the upper connecting pipe 1 and at the bottom of the sealing ring 6. The diameter of the bottom of the guide ring 12 is smaller than the diameter of the lower flow hole 71. With the setting of the guide ring 12, when the upper drain pipe is draining normally, after the water flows into the upper flow hole 11, the guide ring 12 will guide the water flow. The bottom diameter of the guide ring 12 is smaller than the diameter of the lower flow hole 71, which can just gather the water flow and make it flow into the lower flow hole 71, reducing the problem of water overflowing through the drain cavity 3 when the water flow is too large.

[0035] Furthermore, the outer wall of the connecting ring 4 is provided with a connecting groove 42, and the inner wall of the support cylinder 2 is fixedly installed with a locking block 21 that is compatible with the connecting groove 42. The connecting groove 42 consists of an entry section, a translation section and an end section from bottom to top.

[0036] When installing the connecting ring 4, align the entry section at the bottom of the connecting groove 42 with the locking block 21, then press the connecting ring 4 down so that the locking block 21 moves through the entry section to the translation section. At this time, rotate the connecting ring 4 so that the locking block 21 moves through the translation section into the end section. Finally, continue to move the connecting ring 4 down so that the locking block 21 enters the top of the end section. In actual use, the user can select a suitable hole diameter for the drain hole 41 according to the on-site environment and fix the connecting ring 4 on the upper connecting pipe 1. Then, the upper connecting pipe 1 is fixed to the top inside by the connecting ring 4.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
