1) The flange design of the top cover of the water tank is formed with the waterproof layer of the bathroom to form a lap joint mechanism that folds downwards, so that the waterproof layer can effectively cover the installation gap between the water tank and the floor installation hole, without using concrete filling At the same time, the end of the waterproof layer is located on the top cover of the water tank, which forms a height difference with the waterproof layer at the ground, so that the ground water can be guided to the top of the water tank and discharged into the water tank, and The water can not be reversed from the waterproof layer and the joint cover of the water tank top cover, thereby completely solving the problem of water leakage in the pipeline passing through the floor in the prior art;

2) The design of the drain hole of the top cover of the water tank can make the water of the area flow along the waterproof layer to the top cover of the water tank, and then flow into the water tank through the drain hole, which facilitates timely discharge of the ground area water and avoids the floor decoration layer. Leakage caused by the accumulation of water between the waterproof layer and the waterproof layer;

3) Wastewater from floor drains, bathtubs, wash basins, mop pools, etc. can be directly transferred into the waste water drain pipe. Since the waste water drain pipe is directly connected with the water seal box in the water transfer tank, a centralized water seal and deodorization is formed. The structure replaces the multiple water seal designs in the prior art and avoids the problem of indoor back odor caused by failure of a certain water seal;

4) All waste water discharged from the waste water discharge point in the toilet is discharged through the water seal mechanism, so that the water in the water seal mechanism increases the replacement frequency, so that the probability of water evaporation in the water seal mechanism is greatly reduced, and the bathroom is prevented from returning. The odor and the secondary pollution caused by avoiding the evaporation of the water seal have significant technical contributions;

The horizontal pipe occupies the indoor space, and even the side drainage connector is conveniently installed directly in the partition wall, and the horizontal pipe installed on the ground by the wall drainage toilet is reduced to zero occupancy of the bathroom interior space, thereby saving indoor space. Easy to decorate and use. The toilet drain is directly or indirectly connected to the eccentric jack of the rotary plug of the sewage tank, and when the rotary insert is matched with the sewage inlet of the sewage tank, the eccentric joint can be rotated as needed to adjust the corresponding position of the jack and the sewage inlet, and reserve The variation of the installation space is convenient for installation;

6) Integrating the drainage riser and the vent pipe (ie, the riser connection pipe and the upper and lower vent pipe), not only saves the installation space in the toilet, but also realizes the liquid water, solid and gas confluence sewage flow in the drainage riser. The separation of liquid and solids and gas is completed in the integrated drainage device on each floor. The gas in the drainage riser directly enters the vent pipe through the water tank, which realizes separation of water and gas layer by layer, and reduces the drainage riser and the water collection tank. The fluctuation of air pressure inside is beneficial to prevent the water seal mechanism from being damaged by air pressure shock, and to ensure that the indoor air environment is protected from the fouling of the drainage system;

7) The modular same-layer drainage device for building has the advantages of simple structure, scientific design, convenient use, reliable performance, reliable water seal and anti-back odor, and the modular same-layer drainage device for construction is produced according to the design size of the building toilet. The product quality and installation effect are guaranteed to the utmost extent; and in the assembly building, there is no wet work such as grouting of fine stone concrete, and the waterproof layer construction is simple and reliable.
