Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of floor drains, in particular to a floor drain. Background Art
[0002] Current floor drains typically have overflow prevention features. One such mechanism uses a flap to seal one side of the flow channel. When water flows through the flap in one direction, it pushes it open. When water flows in the opposite direction, the flap abuts against the flow channel, sealing it and preventing overflow. However, this flap design is not ideal because when the water flow is low, the flap is not sufficiently powerful to open, leading to water accumulation inside the drain. Utility Model Content

[0004] The utility model discloses a floor drain, comprising a floor drain main body, an opening being provided at the top of the floor drain main body, a cover body being installed at the top of the floor drain main body, the cover body closing the opening at the top of the floor drain main body, a partition being installed on the inner bottom surface of the floor drain main body, the floor drain main body comprising cavity one and cavity two, cavity one and cavity two being respectively located on both sides of the partition, the floor drain main body being provided with an interface, cavity one being communicated with the interface, the partition being provided with through hole one, one axial end of through hole one being communicated with cavity two, and the other axial end of through hole one being capable of being communicated with cavity one, the partition being rotatably connected with a flap, the flap being located at a side of the partition close to cavity two, when the flap is fitted against the partition, the flap blocks through hole one, so that cavity one is separated from through hole one, the floor drain main body being installed with a floating pressure plate, the floating pressure plate being located in cavity two, the floating pressure plate being capable of floating up and down in the water environment of cavity two, the floating pressure plate comprising an extension rod, the extension rod being inserted into through hole one, and in an initial state, the extension rod and the end face of the partition close to cavity one are flush.
[0005] Furthermore, the partition is provided with a second groove body, which is located on the side of the partition close to the first cavity, and the flap includes extension platforms located on both sides, which are inserted into the second groove body.
[0006] Furthermore, the partition includes an inclined surface close to one side of the cavity, and the through hole passes through the inclined surface at one axial end. In the initial state, the flap fits the inclined surface to close one end of the through hole.
[0007] Furthermore, the water flow in the floor drain body can flow from cavity 2 along through hole 1 to cavity 1, and the water flow in cavity 2 flows through the flap, which flips upward to open through hole 1.
[0008] Furthermore, the floor drain body is provided with a bottom surface, which is located at the bottom of the second cavity, and the bottom surface gradually slopes downward in a direction close to the through hole.

DETAILED DESCRIPTION
[0018] The following will clearly and completely describe the technical solutions in this embodiment with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] like Figure 1 、 Figure 2 As shown, a floor drain includes a floor drain body 1, which is an elliptical three-dimensional structure. The floor drain body 1 is provided with an interface 11, through which the water in the floor drain body 1 is discharged. The top of the floor drain body 1 is provided with an opening and a cover body 5 is installed at the opening. The cover body 5 closes the top opening of the floor drain body 1.
[0020] like Figure 2As shown, a partition 2 is installed on the inner bottom surface of the floor drain body 1, and the partition 2 extends upward along the inner bottom surface of the floor drain body 1. The partition 2 is assembled or integrally formed with the inner bottom surface of the floor drain body 1, and the partition 2 divides the floor drain body 1 into two cavities, cavity 12 and cavity 2 13. Among them, the cavity 12 on the left is connected to the interface 11, and the cavity 1 12 on the left is connected to the interface 11. Figure 1 The floor drain body 1 is provided with a groove body 14 on the periphery thereof. The groove body 14 passes through the circumferential outer wall of the floor drain body 1. There are multiple groove bodies 14 distributed along the periphery of the floor drain body 1. The groove body 14 is only distributed on one side of the cavity 2 13 of the floor drain body 1. The groove body 14 is connected to the cavity 2 13. Water from the outside flows into the cavity 2 13 through the groove body 14 of the floor drain body 1.
[0021] like Figure 2 As shown, the partition 2 is provided with a through hole 1 21, which passes through the partition 2 from left to right. One axial end of the through hole 1 21 is connected to the cavity 2 13, and the other axial end of the through hole 1 21 can be connected to the cavity 1 12. Specifically, the right axial end of the through hole 1 21 is directly connected to the cavity 2 13. Figure 3 The partition 2 is provided with a second groove 23 on either side, and a flap 4 is mounted on each side of the second groove 23. The flap 4 is located on the side of the partition 2 near the second cavity 13. The flap 4 includes two extension platforms 41 on each side. The extension platforms 41 are round rod structures and are inserted into the second groove 23. The extension platforms 41 can rotate along their own axis to achieve the flipping of the partition 2. The partition 2 includes an inclined surface 22 near the side of the first cavity 12. The through hole 1 21 axially extends through the inclined surface 22 at one end. In the initial state, no water flows into the second cavity 13. The flap 4 is in contact with the inclined surface 22 to close one end of the through hole 1 21, thereby separating the first cavity 12 from the through hole 1 21. When water flows into cavity 12, it flows from cavity 2 13 along through hole 1 to cavity 1 12. The water in cavity 2 13 flows through flap 4, which drives flap 4 to flip upward, opening through hole 1 21, allowing water to flow out from interface 11 along cavity 1 12.
[0022] like Figure 2 As shown, the floor drain body 1 includes a bottom surface 15, the bottom surface 15 is located at the bottom of the cavity 2 13, and the bottom surface 15 gradually tilts downward along the direction close to the through hole 1 21, combined with Figure 3 , through hole 1 21 is a circular hole, Figure 2 In the figure, the connection point P between the bottom surface 15 and the through hole 1 21 is a low-lying area of the bottom surface 15 to facilitate drainage.
[0023] like Figure 2 As shown, the floor drain body 1 is equipped with a floating pressure plate 3, combined with Figure 4 The cross section of the floating pressure plate 3 is the same as that of the second cavity 13. The floating pressure plate 3 is located in the second cavity 13. The floating pressure plate 3 is provided with a plurality of second through holes 31. The second through holes 31 pass through the floating pressure plate 3 up and down. After water enters the second cavity 13, the floating pressure plate 3 can float up and down in the water environment of the second cavity 13.
[0024] like Figure 2 As shown, the floating pressure plate 3 includes an extension rod 32, combined with Figure 3 , the extension rod 32 is a round rod, and the extension rod 32 is inserted into the through hole 12. In the initial state, the extension rod 32 is flush with the end face of the partition 2 close to the cavity 12. At this time, the flap 4 fits the inclined surface 22, and the extension rod 32 just abuts the flap 4. When the floating pressure plate 3 floats up, the extension rod 32 moves upward to push the flap 4 to flip upward. When there is less water flow in the cavity 2 13, the flap 4 cannot be flipped upward to open the through hole 1 21 by the action of the water flow alone, which causes water accumulation. The pressure of the water in the cavity 2 13 by the floating pressure plate 3 increases the pressure of the water on the flap 4 to the left horizontally. At the same time, the floating pressure plate 3 floats upward, and the extension rod 32 pushes the flap 4 upward. The two forces combine to produce an oblique force in the upper left direction on the flap 4, and cooperate with Figure 2 The position of the middle flap 4 in the initial state makes it easier for the flap 4 to be flipped, thereby opening the first through hole 21 and preventing water from accumulating in the second cavity 13 .
[0025] When the water in the water pipe overflows, the water flows into cavity 12. Under the action of the water pressure in cavity 12, the flap 4 presses the inclined surface 22 to prevent the water from flowing into through hole 1 21 and cavity 2 13, thereby preventing the water from overflowing from trough 14 to the floor drain body 1, solving the problem of odor after overflow.
[0026] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
