[0020] By adopting the foregoing technical scheme, the utility model has the advantages of:
[0021] 1. The floor drain is provided with a rubber sheet opening and closing element. When water flows from the floor drain cover to the floor drain core, the water exerts force on the rubber sheet, causing the rubber sheet to elastically deform downward, thereby realizing the drainage function of the drainage seat. When water stops flowing, the rubber sheet rebounds and tightly adheres to the drainage seat, blocking the drainage hole on the drainage seat and preventing odors or pests in the drainage pipe from entering through the drainage hole.
[0022] 2. The inner core pipe is provided with an intercepting ring. During water flow, hair is entangled on the intercepting block on the intercepting ring, thereby intercepting hair in the water flow and effectively preventing hair from entering the drainage pipe and causing blockage.
[0023] 3. The floor drain cover is provided with a plurality of mounting shells, which can be installed on different floor drain mounting openings. When different shapes of mounting shells are needed, only the connecting block between the mounting shells needs to be cut, and the appropriate mounting shell can be selected. At the same time, the intercepting ring can also be cut to match floor drain mounting openings or drainage pipes of different sizes.
[0024] 4. The mounting block at the lower end of the floor drain is equipped with a protrusion for pulling up the inner core tube. By engaging the protrusion with the drain groove, the entire inner core tube can be easily pulled up for convenient replacement.
[0025] 5. This floor drain is made of plastic material. When facing different installation ports, you only need to break the connecting block between the installation shells, which is simple and convenient. Attached Figure Description

[0032] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0033] refer to Figures 1 to 6 The present invention discloses a floor drain, including a floor drain cover 1 and an inner core tube 2 for drainage. The floor drain cover 1 is disposed at the upper end of the inner core tube 2 and has a plurality of drainage holes. The inner core tube 2 is provided with a conical drainage seat 3 and has a plurality of drainage holes. The lower end of the conical drainage seat 3 is provided with an opening and closing member 4 and a locking connection device is provided between the opening and closing member 4 and the inner core tube 2.
[0034] The engaging connection device includes a connector 5 on the opening / closing member 4 and a connecting hole 6 on the conical drainage seat 3, wherein the connector 5 engages with the connecting hole 6.
[0035] The opening and closing component 4 is made of rubber.
[0036] The lower end of the connecting hole 6 is provided with a rounded corner 15 to facilitate the insertion of the connector 5.
[0037] The inner core tube 2 is provided with a drainage grid 8, and a connecting device is provided between the drain cover 1 and the inner core tube 2.
[0038] The connecting device comprises a drainage groove 9 arranged on the drainage fence 8, a mounting block 10 arranged at the lower end of the floor drain cover 1, and a protrusion 11 arranged on the mounting block 10, the mounting block 10 is inserted and mounted into the drainage fence 8, and the protrusion 11 is clamped and connected with the drainage groove 9.
[0039] The inner core pipe 2 is provided with an intercepting ring 12, and the intercepting ring 12 is provided with an intercepting block 13 for intercepting hair in the water flow.
[0040] The floor drain cover 1 is provided with a plurality of mounting shells, and the mounting shells are provided with drainage holes. In this embodiment, the mounting shells include a square mounting shell 15, an inner circular mounting shell 16, and an outer circular mounting shell 17. The square mounting shell 15 and the outer circular mounting shell 17 are provided with a connecting block 18, and the inner circular mounting shell 16 and the outer circular mounting shell 17 are provided with a connecting block 18.
[0041] The deodorizing effervescent tablets 7 are placed between the conical drainage seat 3 and the floor drain cover 1.
[0042] The floor drain cover 1 and the inner core pipe 2 are both composed of plastic material.
[0043] Working principle:
[0044] In use, the user cuts the floor drain cover 1 according to the floor drain mounting port, selects a suitable mounting shell, then mounts the floor drain cover 1 on the inner core pipe 2, inserts the mounting block 10 into the drainage fence 8, and clamps and inserts the protrusion 11 into the drainage groove 9. When the floor drain is replaced, the inner core pipe 2 is pulled up, and finally the entire floor drain is mounted on the floor drain mounting port or the drainage pipe.
[0045] In the initial state, the opening and closing piece 4 tightly fits the inner side of the drainage seat, and the peculiar smell and pests in the drainage pipe are isolated. When the water flow flows in, first, the water flow flows from the drainage port on the floor drain cover 1 into the inner core pipe 2, and the intercepting block 13 on the intercepting ring 12 blocks the hair in the water flow to prevent the hair from entering the drainage pipe and causing blockage. At the same time, the drainage fence 8 also intercepts part of the debris on the intercepting ring 5. Then, the water flow flows into the conical drainage seat 3, passes through the drainage holes on the conical drainage seat 3, and flows onto the opening and closing piece 4. Under the continuous impact of the water flow, the opening and closing piece 4 elastically deforms downward and gradually moves away from the conical drainage seat 3, and a gap is formed between the opening and closing piece 4 and the conical drainage seat 3. The water flow flows into the drainage pipe through the gap. When flowing into the drainage pipe, the water will impact the deodorizing effervescent tablets 7 to deodorize. After the water flow ends, the opening and closing piece 4 rebounds and reattaches to the conical drainage seat 3, isolating the peculiar smell and pests in the drainage pipe.
[0046] The above-described embodiments are merely illustrative for the application and any modification, change, or improvement made by any person skilled in the art with the application shall fall within the scope of the patent claimed by the application, and are not limited to the embodiments disclosed.
