The upper end of the deflector 311 is connected with a limit plate 312 extending downward. The limit plate 312 is arranged vertically. The inner peripheral wall surface is in contact, and a sliding block 314 matched with the sliding groove 62 is provided on the side of the spiral deflector 311 away from the floating sleeve 31 .

The rotating sleeve 41 is rotatably connected to the lower end of the sewer pipe 21, and a plurality of overflow structures are evenly distributed on the outer peripheral wall of the rotating sleeve 41. The overflow structure includes an overflow plate 413 and a rotating side plate 412 arranged in turn in a clockwise direction, and a connection overflow plate. 413 and the water seal bottom plate 411 at the lower end of the rotating side plate 412 to form a water seal groove, the height of the rotating side plate 412 is higher than the height of the overflow plate 413, and the rotating side plate 412, the overflow plate 413 and the water seal bottom plate 411 One end of the rotating sleeve 41 is in contact with the inner peripheral wall surface of the floor drain outer cylinder 6 .

The lower end surface of the floating sleeve 31 is in contact with the upper end surface of the rotating sleeve 41, the outer diameter of the floating sleeve 31 is larger than the outer diameter of the rotating sleeve 41, and each spiral deflector 311 is located between the two rotating side plates 412, And the upper end of the rotating side plate 412 on the counterclockwise side of the spiral deflector 311 is located between the spiral deflector 311 and the limiting plate 312 connected to the spiral deflector 311 . The lower end of the spiral deflector 311 is inserted into the water seal groove between the two rotating side plates 412, and there is a gap between the lower end of the spiral deflector 311 and the upper surface of the water seal bottom plate 411, and the lower spiral surface of the spiral deflector 311 and the overflow plate. There are gaps between 413.

The unlocking sleeve 71 is inserted into the interior of the sewer pipe 21 and rotates along the rotating sleeve 41 . The unlocking sleeve 71 includes a twist ring 711 and a connecting column 712 . The connecting column 712 is connected to the lower end of the twist ring 711 and is evenly distributed along the circumferential direction of the twist ring 711 . , the twist ring 712 protrudes from the upper end surface of the water pipe 21 , the lower end of the connecting column 712 is connected to the rotating sleeve 41 , and the lower end of the chute 62 is below the water seal bottom plate 411 .

In this embodiment, as shown in FIG. 4 , when the ground drain does not work or a small flow of ground water passes between the drain pipe 21 and the ground drain outer cylinder 6 , the water flows through the spiral deflector 311 to the water seal groove, and From the gap between the spiral deflector 311 and the water seal bottom plate 411, it flows over the upper end of the overflow plate 413 into the lower end of the floor drain outer cylinder 6, and the water flow closes the gap between the spiral deflector 311 and the water seal bottom plate 411 to form a water seal to seal the floor drain. Isolate odors. Due to the functions of the water sealing bottom plate 411, the overflow plate 413 and the rotating side plate 412, the water in the water sealing groove will not be sucked away by the indoor drainage pipe due to the siphon effect, which improves the sealing reliability of the overflow structure.

As shown in FIG. 6 , when a large flow of ground water passes between the downpipe 21 and the outer pipe of the floor drain, the overflow plate 413 does not drain well enough that the water flow will gather between the spiral deflector 311 and the rotating side plate 412. When the water flow gathers After a certain degree, the force of the water on the lower surface of the floating sleeve 31 increases, and the floating sleeve 31 moves upward along the floor drain outer cylinder 6 under the action of the water, and drives the spiral deflector 311 to move upward, while the water flows along the spiral guide. The flow plate 311 flows against the rotating side plate 412, and the rotating side plate 412 rotates counterclockwise along the downpipe 21 through the rotating sleeve 41 under the impact of the water flow. When the flow plate 311 rises and exits the water seal groove, and the spiral baffle 311 and the rotating side plate 412 are separated from each other, the water outlet on the lower side of the spiral baffle 311 will be enlarged to speed up the drainage speed.

In this embodiment, when the floor drain inner core 1 needs to be disassembled, the twist ring 711 is first rotated clockwise. The twist ring 711 drives the connecting column 712 and then drives the rotating sleeve 41 to rotate counterclockwise. During the counterclockwise rotation of the rotating sleeve 41, The rotating side plate 412 pushes the spiral deflector 311 to rise, and at the same time, the water seal groove passes through the chute 62 so that the accumulated water in the water seal groove flows out along the chute 62 . Lift up the twist ring 71 to disassemble the floor drain inner core 1. Since the accumulated water in the water seal groove has been discharged from the chute 62, it can be avoided that when the floor drain inner core 1 is pulled upwards, the sewage in the water seal groove will be taken out, which will affect the building ground. cleanliness of the environment.

In this embodiment, the lower end of the outer peripheral wall of the downpipe 21 is provided with guide holes 215 extending along the circumferential direction of the downpipe 21 . The floor drain inner core 1 also includes several arc-shaped wedges 714 and several flaps 51 .

The arc-shaped wedges 714 are fixedly connected to the lower end of the connecting column 712 and are evenly distributed along the circumferential direction of the unlocking sleeve 71, and the distance from the arc wedge surface of the arc-shaped wedges 714 to the center of the unlocking sleeve 71 gradually decreases in the clockwise direction; The wedge block 714 is located inside the sewer pipe 21 and is connected with the rotating sleeve 41 by connecting bolts (not shown in the figure), the connecting bolts pass through the guide holes 215 and slide in the guide holes 215, so that the curved wedge blocks 714 is rotatably connected to the sewer pipe 21 .

The inner end of the flap 51 is hinged to the lower end of the downpipe 21 and is evenly distributed along the circumferential direction of the downpipe 21. The flap 51 is located below the rotating sleeve 41, and the inner end of the flap 51 is provided with an arc-shaped wedge 714 extending to the The elongated column 511 at the bottom, so that when the water flow hits the flap 51, the flap 51 is turned downward, so that the inner end of the elongated column 511 presses the lower edge of the arc wedge surface upward, and promotes the arc wedge 714 Rotate clockwise, thereby driving the rotating sleeve 41 to rotate.

The elongated column 511 is vertically connected to the middle of the inner end surface of the flap 51 . In two adjacent overflow structures, the opening between the overflow plate 413 of one overflow structure and the rotating side plate 412 of the other overflow structure is a communication port, and each flap 51 is located on the lower side of one communication port. Specifically, the flap 51 includes an upper surface, a lower surface and a peripheral wall surface, the peripheral wall surface includes a circular arc surface, two first vertical planes and a second vertical plane, the outer ends of the two first vertical planes are respectively Connected with both ends of the arc surface, the inner ends of the two first vertical planes are close to each other and are respectively connected with both ends of the second vertical plane, the arc surface and the floor drain outer cylinder 6 are coaxially arranged and the arc The diameter of the surface is the same as the inner diameter of the floor drain outer cylinder 6 . The inner end surface of the flap 51 (ie, the second vertical plane) is a vertical plane, which can prevent the flap 51 from interfering with the sewer pipe 21 when the flap 51 is turned downward.

In this embodiment, when the floor drain is not working or a small flow of ground water passes between the drain pipe 21 and the floor drain outer cylinder 6 , the flap 51 is in a downwardly inclined posture under the blocking of the arc-shaped wedge 714 . When the ground water flow increases, causing the spiral deflector 311 to exit the water seal groove, the water flowing down the spiral deflector 311 will impact the flap 51, and the flap 51 will turn downward under the impact force of the water flow, thereby making the extension The inner end of the long column 511 is lifted up to press the lower edge of the arc wedge surface, and the lower edge of the arc wedge surface is pressed to cause the arc wedge block 714 to rotate clockwise along the water pipe 21 through the cooperation of the connecting bolt and the guide hole 215, In turn, the rotating sleeve 41 is driven to rotate. The impact of the rotating sleeve 41 on the water flow and the pressing effect of the flap 51 on the arc-shaped wedge 714 make it rotate rapidly under the double action, so that the spiral deflector 311 quickly moves to the upper limit position, and the water outlet is increased to the maximum. , the large flow of water flows quickly through the sewer. After the water flow decreases to a certain extent or after the water is discharged, the floating sleeve 31 drives the spiral deflector 311 to descend, and the spiral deflector 311 descends and presses the rotating side plate 412 , and the rotating side plate 412 passes the rotating sleeve 41 along the downward direction The water pipe 21 is rotated counterclockwise to return to its original position, and at the same time, the flap 51 returns to its original position under the pressure of the arc-shaped wedge 714 .

The outer end of the flap 51 is turned downward. When the arc-shaped wedge block 714 moves until the extension column 511 is in contact with the limit block 715, the limit block 51 guides the extension column 511 to move downward suddenly, and the extension column 511 moves toward the limit block 511. The downward movement causes the outer end of the flap 51 to be turned upward. When the elongated column 511 moves downward until its upper surface is in contact with the lower surface of the limit block 715, the flap 51 is turned to the horizontal position, and the rotating sleeve 41 is rotated at the same time. Until the water seal groove is located directly above the flap 51, the debris blocked on the flap is squeezed between the flap 51 and the water seal bottom plate 411, so that when the floor drain inner core 1 is pulled upward, the flap 51 The sundries are brought out smoothly, so as to avoid sundries falling into the room caused by dismantling the floor drain inner core 1 when the flap 51 is turned downward, which will affect the indoor floor environment.
