Technical Field

[0001] This utility model relates to the technical field of floor drain equipment, specifically a floor drain device. Background Technology

[0002] In building drainage systems, floor drains are crucial components connecting indoor floors to drainage pipes, primarily used for draining domestic wastewater (such as water accumulation in bathrooms and kitchens). Traditional floor drains typically consist of a cover and a drainage channel, but in practice, the following problems still exist: positive or negative pressure may form inside the drainage pipe due to rapid water flow or changes in external air pressure (such as backflow from sewers or siphon effects), leading to poor drainage and even problems like odors and sewage backflow. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a floor drain device that achieves rapid venting through a mechanical built-in structure and automatically resets after the venting pressure is exhausted.

[0012] Example 1: like Figures 1-4As shown, a floor drain device includes a floor drain cover 2 with a drainage groove 202 and a drainage channel assembly 4 at the bottom. During normal use, water on the floor flows onto the floor drain cover 2 and through the drainage groove 202 into the drainage channel assembly 4, from where it is discharged into a sewage pipe. If the internal air pressure of the sewage pipe increases, the water cannot flow smoothly through the drainage channel assembly, requiring depressurization of the sewage pipe to drain the water. Therefore, the floor drain cover... A second mounting hole 203 is provided on the drain cover 2, and a pressure relief assembly 3 is installed in the second mounting hole 203. The pressure relief assembly 3 can release the air pressure inside the drain pipe. The pressure relief assembly 3 includes a top plate 33, an elastic element 32, a pressure plate 31, and an exhaust hole 204. The top plate 33 is fixed to the bottom of the second mounting hole 203, the elastic element 32 is installed on the top plate 33, the pressure plate 31 is slidably connected in the second mounting hole 203, and the exhaust hole 204 is opened inside the drain cover 2. The opening path of the exhaust hole 204 is L-shaped, and the air intake of the exhaust hole 204 is L-shaped. The drain cover 2 is connected to the internal air pressure of the drain pipe. The exhaust end of the exhaust hole 204 is located on the side wall of the second mounting hole 203. The drain cover 2 is connected to the positioning ring 8 by the first fastener. When in use, it is necessary to release the internal air pressure of the drain pipe. Then, the pressure plate 31 is manually pressed down. The pressure plate 31 slides down along the inner wall of the second mounting hole 203, so that the elastic element 32 is in a compressed state. The pressure plate 31 slides down to below the exhaust end of the exhaust hole 204. The air in the drain pipe is discharged through the exhaust hole 204. After releasing the internal air pressure of the drain pipe, the accumulated water flows through the drain. The drainage channel of the cover plate 2 flows into the drainage pipe. At the same time, the downward force applied to the pressure plate 31 is removed. The elastic element 32 pushes the pressure plate 31 to move upward along the inner wall of the second mounting hole 203 until the top surface of the pressure plate 31 abuts against the bottom surface of the positioning ring 8, so that the pressure plate 31 and the positioning ring 8 form an end face seal. A rubber gasket can be placed between the two to further eliminate the gap between them. The pressure plate 31 slides to the top of the exhaust end of the exhaust hole 204, which can disconnect the air communication between the exhaust hole 204 and the external environment. The elastic element 32 can be a compression spring or a tower spring.

[0013] like Figure 4 As shown, during the venting process, as the air pressure in the sewage pipe decreases, the accumulated liquid will seep into the internal space below through the second mounting hole 203. A guide hole 331 for draining liquid is provided on the top plate 33, and the sewage in the space is subsequently discharged through the guide hole 331.

[0014] like Figure 3As shown, the drainage channel assembly 4 includes an arc-shaped plate 5, a guide pipe 7, and a baffle 6. The top of the arc-shaped plate 5 is connected to the bottom of the drain cover 2, and the bottom of the arc-shaped plate 5 is connected to the guide pipe 7. There is a first gap between the guide pipe 7 and the drain cover 2. The arc-shaped plate 5 and the guide pipe 7 cooperate to form a first receiving groove. The baffle 6 is located between the arc-shaped plate 5 and the guide pipe 7. The bottom of the baffle 6 is inserted into the first receiving groove. After the first receiving groove is filled with liquid, the bottom end of the baffle 6 is immersed in the liquid. The arc-shaped plate 5, the baffle 6, and the guide pipe 7 are staggered. The cloth forms an S-shaped drainage channel. The arc plate 5, the guide pipe 7 and the partition 6 together form an S-shaped drainage channel. In the S-shaped drainage channel, the bottom of the partition (6) is immersed in the liquid in the first receiving tank, forming a water seal height of ≥50mm (national standard requires ≥30mm). Even if the air pressure fluctuates, it can still block harmful gases. When not in use, the arc plate 5 and the guide pipe 7 form a chamber that can store a part of the liquid. The bottom of the partition 6 extends into the liquid, which can prevent irritating gases or insects in the sewage pipe from entering the internal environment.

[0015] like Figure 1 and Figure 2 As shown, the drain cover 2 is connected to the floor by a second fastener. The drain cover 2 has a first mounting hole 201 for the second fastener to pass through. This design prevents the drain cover 2 from being blown off due to excessive air pressure inside the sewage pipe. The second fastener can be an expansion bolt. During installation, holes are pre-drilled in the floor, and then the drain cover 2 is fixed to the drilled holes in the floor using expansion bolts.

[0016] The working principle is as follows: Normal drainage: Surface water flows sequentially through the S-shaped channel formed by drainage trough 202 and drainage channel component 4, and finally flows into the sewage pipe.

[0017] Pressure balancing (pressure relief): When the pressure in the sewage pipe rises, causing drainage obstruction, manually operate the pressure relief component 3: Press down the pressure plate 31 → compress the elastic element 32 → the pressure plate 31 moves down to expose the vent hole 204 → the gas in the pipe is released and pressure is relieved → release the pressure plate 31 → the elastic element 32 resets → the pressure plate 31 moves up and seals with the positioning ring 8 → close the vent hole 204. After pressure relief, the accumulated water can be discharged normally.

[0018] Odor and insect prevention: The liquid stored at the bottom of the S-shaped drainage channel forms a liquid seal, effectively preventing harmful gases and insects from the sewage pipes from entering the indoor environment.
