Description

Technical Field

[0001] This utility model relates to the field of floor drain technology, and in particular to a floor drain for building drainage that prevents backflow of odors. Background Technology

[0002] A floor drain is an important sanitary fixture that connects the drainage system to the indoor floor. It is usually installed in areas that require drainage, such as bathrooms, kitchens, or balconies. Its main function is to quickly direct water on the floor into the drainage pipes, preventing problems such as dampness, slipping, and bacterial growth caused by water accumulation. Floor drains come in a variety of designs and materials to suit different usage environments and decorating styles. Common types of floor drains include U-shaped floor drains, T-shaped floor drains, and flap floor drains. The main materials are stainless steel, copper, and cast iron. When choosing a floor drain, you should consider its drainage efficiency, odor prevention function, durability, and whether it matches the interior decorating style.

[0003] The following problems exist: Common floor drains are mainly used to filter out some debris during the drainage process, thereby effectively preventing the drainage pipes from becoming blocked. However, these ordinary floor drains often lack an important anti-backflow structure. When water flows into the bottom of the floor drain, due to the lack of an effective anti-backflow mechanism, the water may return to the surface of the floor drain. This not only causes water accumulation on the floor, but also fills the room with an unpleasant odor. This odor is often emitted by sewage and impurities in the sewer, which not only affects the comfort of the living environment, but may also pose certain health hazards. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A building drainage anti-odor floor drain includes a drain pipe, a limiting ring fixedly connected to the top of the drain pipe, an insert pipe sleeved at the bottom of the inner wall of the limiting ring, an inlet pipe sleeved at the top of the inner wall of the insert pipe, side plates fixedly connected to the bottom two ends of the inlet pipe, a crossbar fixedly connected to the bottom of the opposite surfaces of the two sets of side plates, a sealing plate rotatably connected to the outer wall of the crossbar, and a U-shaped baffle fixedly connected to the top end of the sealing plate.

[0007] As a further description of the above technical solution:

[0008] The top of the inner wall of the limiting ring is threadedly connected to a top ring, and the inner wall of the top ring is fixedly connected to a perforated plate.

[0009] As a further description of the above technical solution:

[0010] The top ring has grooves at both ends, and a pinch block is fixedly connected to one end of the inner wall of each groove. A rubber ring is fixedly connected to the outer edge of the bottom of the top ring.

[0011] As a further description of the above technical solution:

[0012] A guide inclined block is fixedly connected to one end of the inner wall of the water inlet pipe, and a filter screen is fixedly connected to the bottom end of the inner wall of the water inlet pipe.

[0013] As a further description of the above technical solution:

[0014] A sliding groove plate is installed symmetrically at the bottom of the inner wall of the cannula, and the outer wall of each side plate is sleeved with the inner wall of the sliding groove plate.

[0015] As a further description of the above technical solution:

[0016] Baffles are fixedly connected to the bottom ends of the opposite surfaces of the two sets of sliding plates.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1) The water flowing through the filter screen will fall directly onto the other end of the top of the sealing plate. At this time, the sealing plate will rotate clockwise by a certain angle when pressed. Then the water will flow out from the bottom of the inclined surface of the sealing plate. By setting a U-shaped baffle, a small amount of water can be intercepted. By setting a baffle, not only can the rotation direction of the sealing plate be limited, but the water below can also be intercepted. When the sealing plate is limited, the bottom end of the sealing plate is right next to the top surface of the baffle. At this time, the top surface of the sealing plate is horizontal. At the same time, the sealing plate can block the entire tube. The water below can only flow upward from the other end of the bottom of the sealing plate. However, the sealing plate is blocked by the baffle. The horizontal sealing plate cannot rotate counterclockwise, which can block the water below and thus prevent backflow.

[0019] (2) By setting a groove, it is convenient for the user to insert two fingers into it. By setting a pinch block, it is convenient for the user to press two fingers tightly against its surface. Then, by rotating the fingers, the top ring can be disassembled or fixed. After the top ring is fixed, the rubber ring is pressed on the top of the water inlet pipe, which can fix the water inlet pipe and the insertion pipe. Attached Figure Description

[0028] A rubber ring 8 is fixedly connected to the bottom outer edge of the top ring 4. A water inlet pipe 9 is sleeved on the top of the inner wall of the insertion tube 3. After the top ring 4 is fixed, the rubber ring 8 presses against the top of the water inlet pipe 9, which can fix the water inlet pipe 9 and the insertion tube 3. A guide inclined block 10 is fixedly connected to one end of the inner wall of the water inlet pipe 9. By setting the guide inclined block 10, the water flow can be guided. A filter screen 11 is fixedly connected to the bottom of the inner wall of the water inlet pipe 9. By setting the filter screen 11, impurities in the water flow can be filtered. The guide inclined block 10, the filter screen 11, and the water inlet pipe 9 are all connected together. The bottom surfaces of all are set on the same horizontal plane. Side plates 12 are fixedly connected to both ends of the bottom of the water inlet pipe 9. Horizontal bars 13 are fixedly connected to the bottom of the opposite surfaces of the two sets of side plates 12. A sealing plate 14 is rotatably connected to the outer wall of the horizontal bar 13. A U-shaped baffle 15 is fixedly connected to one end of the top of the sealing plate 14. Water flowing through the filter screen 11 will fall directly onto the other end of the top of the sealing plate 14.
