The floor drain is an important interface for connecting a drainage pipeline system and the indoor ground, is an important part of a residential drainage system, and has the performance that the quality of indoor air and the property safety are directly influenced, and even the life health of people in a residential building is greatly influenced. The water seal floor drain adopts the principle that the floor drain is provided with a trap, so that odor in a pipeline can not come out through a floor drain opening; a standard floor drain product must have a water seal of 50 mm. In order to meet the water seal height, the qualified floor drain products have higher product height (not less than 73mm), so that the building ground is thicker; in order to solve the problem, patent CN 210151888U discloses a structural assembly for preventing water seal splash loss and a drainage floor drain, specifically, a flow guide channel, i.e. an independent inner flow channel 8 in fig. 1, is arranged between an inner cavity and an outer cavity forming a water seal, a water inlet end of the flow guide channel is located at the lower end of the outer cavity and is communicated with the outer cavity, and a water inlet end of the flow guide channel is lower than a water return cover and higher than a communication position of the inner cavity and the outer cavity. This structure has been solved when reducing drainage product mounting height, avoids the water seal loss problem of splashing.

However, in the process of practical use, the water seal floor drain is still found to have a problem that: when negative pressure is generated in the sewer pipe, the water seal in the independent inner flow passage 8 can splash out from the opening of the upper flow passage, so that the water seal is sucked away by the negative pressure of the pipeline, the water seal effect is weakened, and the deodorization function of the floor drain is reduced.

Furthermore, the drainage structure is arranged in the main shell and the water seal cover, the main shell is a shell with an opening at the upper part, a tubular drainage cavity is arranged in the main shell, the opening of the water seal cover is downwards buckled above the drainage cavity, so that an outer cavity is formed between the water seal cover and the main shell, an inner cavity is formed between the water seal cover and the drainage cavity, and the independent inner flow passage is detachably connected to the water seal cover; the water retaining weir is fixedly connected to the top wall of the inner side of the water sealing cover.

Furthermore, the independent inner runner is clamped on the water seal cover through a connecting piece.

Furthermore, the independent inner flow passage is in any one of a U shape, a V shape and an arc shape.

Furthermore, a plurality of independent inner flow channels are arranged between the inner cavity and the outer cavity.

Furthermore, the length of the arc is matched with the length of the top outlet of the independent inner flow passage.

The utility model provides a floor drain with manger plate structure drainage subassembly, includes main casing body and water seal cover, be equipped with the structure subassembly that can prevent that the water seal from splashing in main casing body and the water seal cover.

The working principle of the water retaining weir is as follows:

when the pipeline generates negative pressure, water in the outer cavity enters the independent inner flow channel, when the water in the independent inner flow channel is pumped out at a high speed, the water is beaten on the water retaining weir, the water blocked by the water retaining weir falls back into the inner cavity, the inner cavity is communicated with the outer cavity, and the water in the inner cavity flows back to the outer cavity. Thus, the internal circulation of the floor drain is formed, and the loss of water in the floor drain is avoided.

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

the utility model aims at the improvement of parts and structure of the water seal floor drain with an independent inner flow passage design. The floor drain is provided with the independent flow channel and the water retaining weir structure, so that water loss in the floor drain is effectively prevented, and the water sealing and deodorizing functions of the floor drain are more effectively guaranteed. The structure has the advantages that: after the water retaining weir structure is used, water in the floor drain can form effective internal circulation under the action of negative pressure of the pipeline, so that the water in the floor drain is not lost.
