[0039] The filter ring is disposed between the outer support column 111 and the inner support column 112, and the filter ring is coaxially disposed with the drainage cylinder 115;

[0040] The bottom cover 140 is as Figure 4 As shown, it includes a cylinder body 144 sleeved on the outside of the drainage cylinder 115 and a lower bottom ring 143 sleeved on the outside of the cylinder body 144, the lower bottom ring 143 is abutted against the lower end of the filter ring, the cylinder body 144 is provided with a second straight groove edge 142 at a position corresponding to the drainage guide groove 114, and the cylinder body 144 is provided with a second straight groove 141 at a position corresponding to the first groove edge 113.

[0041] The secondary drainer 100 in this embodiment can drain the water accumulated in the mortar filling layer 302 to avoid the indoor decoration being affected by underground water accumulation, such as ground warping, water seepage, mildew, etc.;

[0042] The main drainage floor drain 201 flow channel and the mortar filling layer 302 flow channel can share a drainage pipe, two in one, avoiding the need for additional pipelines, and the main body diameter and depth of the secondary drainer 100 can be adapted to most floor drains 201 on the market, effectively reducing the height of the mortar filling layer 302, saving decoration costs, and enhancing the market competitiveness of this product.

[0043] The secondary drainer 100 in this embodiment has a reasonable and simple structural design, low manufacturing cost, is easy to mass produce and convenient to assemble and construct. During construction, the product bottom cover 140 can play a role in positioning the drainage pipe and assisting in leveling the waterproof layer 303, providing convenience for construction.

[0044] It should be noted that, in this embodiment, the material of the main body 110 and the bottom cover 140 can be selected as needed, and can withstand the pressure of 30 cm deep mortar filling without deformation, and can be used in conjunction with the PVC-U drainage system.

[0045] In an optional embodiment, the filter ring includes a multi-pleated filter mesh 120 and a porous metal outer ring 130 sleeved on the outside of the multi-pleated filter mesh 120 .

[0046] The porous metal outer ring 130 can block the passage of solid fillers with large particles (such as expanded clay, gravel, etc.) in the mortar filling layer 302, which can effectively block the fillers to avoid clogging the pipeline, and is beneficial to protecting the multi-pleated filter screen 120 from deformation due to local external forces, thereby improving the overall mechanical properties of the product.

[0047] The pleated structure of the multi-pleated filter screen 120 can increase the surface area of ​​the filter screen and the filtering area, so that the water in the mortar filling can penetrate and filter while avoiding clogging of the main pipe in the middle of the drainage tube 115.

[0048] The secondary drainer 100 can be assembled before use. The specific assembly method can be: the porous metal outer ring 130 is sleeved on the multi-pleated filter screen 120, installed between the outer ring support column 111 and the inner ring support column 112 of the main body 110, and pressed tightly. Finally, the first groove rib 113 on the main body 110 is matched with the second straight groove 141 on the bottom cover 140, and the drainage guide groove 114 on the main body 110 is matched with the second straight groove rib 142 on the bottom cover 140, and they are installed and pressed tightly.

[0049] It should be noted that the materials of the porous metal outer ring 130 and the multi-pleated filter screen 120 can be selected as needed, as long as they can withstand the pressure of the mortar filler under installation conditions without deformation.

[0050] In an optional embodiment, the holes on the porous metal outer ring 130 are larger than the mesh holes of the multi-pleated filter screen 120 .

[0051] The porous metal outer ring 130 blocks larger particles, while the multi-pleated filter mesh 120 further blocks smaller particles from entering the main pipeline in the middle of the drainage tube 115, thereby achieving graded filtration, which is more conducive to the penetration and filtration of water in the mortar filling and avoids clogging the main pipeline in the middle of the drainage tube 115.

[0052] In an optional embodiment, the multi-pleated filter screen 120 includes an inner ring 121 and a multi-pleated ring 122 fixed outside the inner ring 121 .

[0053] The multi-pleated filter screen 120 is a structure of a multi-pleated ring 122 + an inner ring 121. The multi-pleated structure increases the blocking area, but it also makes its structural stability poor and prone to deformation. The inner ring 121 and the multi-pleated ring 122 are fixed to form multiple relatively stable semi-cylindrical structures between the two, which is beneficial to improving the stability of the multi-pleated filter screen 120.

[0054] In an optional embodiment, a bent portion 131 that bends inward is provided at the bottom of the porous metal outer ring 130 , and the bent portion 131 covers the gap between the inner ring 121 and the multi-fold ring 122 .

[0055] The curved portion 131 covers the bottom of the gap between the inner ring 121 and the multi-fold ring 122, which can prevent particles from entering between the inner ring 121 and the multi-fold ring 122 from the bottom of the gap between the inner ring 121 and the multi-fold ring 122, blocking the multi-fold filter screen 120 and reducing the filtering efficiency.

[0056] In an optional embodiment, the inner ring support column 112 and / or the outer ring support column 111 are surrounded by two or more pillars, and a gap is provided between two adjacent pillars.

[0057] The gaps between adjacent pillars corresponding to the inner circle support pillars 112 or the adjacent pillars corresponding to the outer circle support pillars 111 can initially block large particles. At the same time, the support pillars have a certain strength, which is conducive to improving the stability of the structure.

[0058] In an optional embodiment, the distance between the outer ring support column 111 and the inner ring support column 112 is adapted to the radial width of the filter ring. The outer ring support column 111 and the inner ring support column 112 clamp the filter ring in the middle, which can protect the filter ring.

[0059] In an optional embodiment, a stepped tapered structure is provided at the bottom of the drainage tube 115, which, while ensuring the diversion function of the drainage diversion groove 114, expands the diameter and deepens the insertion port to fully utilize the space. It can be directly used with a variety of floor drains 201 on the market, effectively reducing the required height of the mortar filling layer 302, saving materials for mortar filling, and saving installation costs.

When in use, the hidden secondary drainer 100 of the present application is installed under the floor tile layer 301 on the ground, embedded in the mortar filling layer 302, and above the waterproof layer 303. Its upper end is connected to the floor drain 201 through the first drain pipe 202, and its lower end is inserted into the second drain pipe 203. The top end of the second drain pipe 203 is flush with or slightly higher than the waterproof layer 303, and the top end of the second drain pipe 203 is connected to the mortar filling layer 302.

[0065] During use, the main water flow will pass through the floor drain 201, flow through the main drainage channel composed of the floor drain 201, the first drain pipe 202, the hidden secondary drain 100 body 110, and the second drain pipe 203, and naturally enter the main drainage system under the action of gravity. A small amount of water will penetrate into the water in the mortar filling layer 302 along the gaps in the floor tile layer 301, and under the action of the waterproof layer 303, it will continue to accumulate in the mortar filling layer 302. When there is water accumulation in the mortar filling layer 302, the water will pass through the porous metal outer ring 130 and the multi-pleated filter 120, along the drainage guide groove 114 of the hidden secondary drain 100 body 110, flow into the second drain pipe 203, and merge into the main drainage system.

[0066] There are a plurality of drainage guide grooves 114 on the main body 110 of the hidden secondary drain 100 , which allow the accumulated water in the mortar filling layer 302 to be collected from multiple directions and enter the second drainage pipe 203 .
