After the installation is completed, the cover plate 5 is removed for use. When it is used for drainage, the water on the floor enters from the waterproof and odor-proof component, and then flows into the secondary drainage regulating pipe 3 through the waterproof and odor-proof component. At this time, the water that penetrates into the floor will fall on the secondary drainage guide plate 4, and flow into the secondary drainage regulating pipe 3 through the secondary drainage guide plate 4. The water entering the secondary drainage regulating pipe 3 enters the floor drain body 1 through the floor drain filter element, and then flows out from the floor drain body 1, and the floor drain body 1 is connected to the sewer pipe.

[0020] In this embodiment, by Figure 1-2As shown, the deodorizing and waterproofing assembly includes a placement tube 6 placed on the secondary drainage guide plate 4, the placement tube 6 is located in the secondary drainage regulating tube 3, the outer ring diameter of the placement tube 6 is smaller than the inner ring diameter of the secondary drainage regulating tube 3, a gap is provided between the placement tube 6 and the secondary drainage regulating tube 3, a circular ring is fixed on the placement tube 6, and the outer ring diameter of the placement tube 6 is also smaller than the inner ring diameter of the secondary drainage guide plate 4, the diameter of the circular ring is larger than the inner ring diameter of the secondary drainage guide plate 4, the placement tube 6 is placed on the secondary drainage guide plate 4 through the circular ring, a floor drain plate 8 is fixed on the placement tube 6, a floor drain shell 7 is placed inside the placement tube 6, and a floor drain shell 7 is fixed on the placement tube 6 A floor drain plate 8 is provided, a floor drain shell 7 is placed inside the placement tube 6, the floor drain shell 7 is provided with a flow cavity 18, a baffle 9 rotatably connected to the floor drain shell 7 is provided at the flow cavity 18, the lower end surface of the baffle is in contact with the floor drain shell, and the angle between the floor drain shell and the lower end of the baffle is an acute angle, so that the baffle and the floor drain shell form a unidirectional conductive structure capable of draining water downward, a V-shaped hair filter net 10 is placed on the floor drain shell 7, a V-shaped hair filter net 10 is placed on the floor drain shell 7, the edge of the V-shaped hair filter net 10 is a circle, and the V-shaped hair filter net 10 is placed on the upper side wall of the floor drain shell 7 through the circle, thereby filtering the water flow and debris falling from the top of the floor drain shell 7.

[0021] In this embodiment, by Figure 1-2 As shown, a lower arc plate 16 is fixed on the floor drain shell 7, an inclined plate 17 is fixed on the floor drain shell 7, the baffle 9 is rotatably mounted on the floor drain shell 7 through the inclined plate 17, the baffle 9 is rotatably mounted on the inclined plate 17 through a bearing, the flow chamber 18 is located between the lower arc plate 16 and the inclined plate 17, and the angles between the baffle 9 and the lower arc plate 16 and the inclined plate 17 are all acute angles;

[0022] The floor drain plate 8 is flush with the floor, the water flows into the floor drain plate 8, then passes through the V-shaped hair filter 10 to filter out hair and debris, and then enters the floor drain shell 7, the water falls from above, and the water pushes the baffle plate 9 to rotate around the central axis of the connection position with the inclined plate 17 by gravity, so that the water flows out from the flow cavity 18 between the lower arc plate 16 and the inclined plate 17, and then flows out from the floor drain shell 7 into the secondary drainage regulating pipe 3. The baffle plate 9 cooperates with the design of the inclined plate 17 and the lower arc plate 16, so that the water in the flow cavity 18 can push the baffle plate 9 to rotate and then flow out, and the baffle plate 9 can be used to prevent the water from flowing out of the secondary drainage regulating pipe 3. Plate 9 is tilted and buckled on the inclined surface of the lower arc plate 16. Due to the influence of gravity, the baffle 9 fits with the inclined surface of the lower arc plate 16. When the water flow and gas in the secondary drainage regulating pipe 3 flow from bottom to top, the water flow and gas will press the baffle 9 to rotate in the direction of the lower arc plate 16, causing the baffle 9 to fit tightly with the lower arc plate 16. Therefore, the water and gas in the secondary drainage regulating pipe 3 cannot push the baffle 9 to rotate, thereby preventing the sewage odor from flowing back from the secondary drainage regulating pipe 3 to the floor. This is secondary waterproofing and odor prevention. The V-shaped hair filter 10 and the floor drain shell 7 can be taken out for easy cleaning.

[0023] In this embodiment, by Figure 1-2 As shown, the secondary drainage guide plate 4 is provided with a plurality of guide grooves 11, and the plurality of guide grooves 11 are evenly distributed around the secondary drainage guide plate 4. The plurality of guide grooves 11 are separated by a plurality of radial plates on the secondary drainage guide plate 4. A ferrule is fixed on the placement tube 6, and the placement tube 6 is placed on the radial plate of the secondary drainage guide plate 4 through the ferrule. The outer ring diameter of the placement tube 6 is smaller than the inner ring diameter of the secondary drainage regulating tube 3, so that a gap is formed between the placement tube 6 and the secondary drainage regulating tube 3, and the outer ring diameter of the ferrule on the placement tube 6 is larger than the inner ring diameter of the secondary drainage regulating tube 3, so that the water seeping under the floor will fall on the secondary drainage guide plate 4, and then flow from the guide groove 11 into the gap between the placement tube 6 and the secondary drainage regulating tube 3, and then flow into the secondary drainage regulating tube 3, so as to prevent water from seeping under the floor and then staying on the waterproof layer to cause mold.

[0024] In this embodiment, by Figure 1-2 As shown, a support frame 12 is fixed on the floor drain body 1 , and the floor drain core 2 is placed in the floor drain body 1 through the support frame 12 .

[0025] In this embodiment, by Figure 1-2 As shown, a plurality of clamping rings 14 are fixed on the secondary drainage regulating pipe 3, and a clamping ring 13 which is sleeved on the secondary drainage regulating pipe 3 is arranged between the two lowest clamping rings 14, and the clamping ring 13 is made of elastic material, and the clamping ring 14 is made of elastic material. When the secondary drainage regulating pipe 3 is inserted into the support frame 12, the clamping ring 13 cooperates with the support frame 12 to make the secondary drainage regulating pipe 3 plugged into the support frame 12, and the secondary drainage regulating pipe 3 is installed on the floor drain body 1 through the support frame 12.

[0026] In this embodiment, by Figure 1-2 As shown, a retaining ring 15 is fixed inside the floor drain body 1, the diameter of the floor drain inner core 2 is smaller than the inner ring diameter of the retaining ring 15, and the lower side wall of the floor drain inner core 2 is lower than the upper side wall of the retaining ring 15. Each time water is drained, a portion of water will remain in the floor drain body 1, and the water level is higher than the lower side wall of the floor drain inner core 2 and lower than the upper side wall of the retaining ring 15. When the odor in the sewer pipe flows back through the floor drain body 1, it will be blocked by the water between the retaining ring 15 and the floor drain inner core 2 in the floor drain body 1, so that the odor cannot flow back into the secondary drainage regulating pipe 3, and thus cannot flow out of the floor drain. This is a primary deodorization.

[0027] When the floor drain body 1 is blocked, the floor drain shell 7, the V-shaped hair filter 10 and the floor drain inner core 2 can be taken out, and then the floor drain body 1 can be unblocked by using tools or manually.

[0028] When the utility model is used, the floor drain plate 8 of the floor drain is flush with the floor, and the secondary drainage guide plate 4 is installed flush with the waterproof layer under the floor. Each time water is drained, a portion of water will remain in the floor drain body 1. When the odor in the sewer pipe flows back through the floor drain body 1, it will be blocked by the water between the retaining ring 15 and the floor drain inner core 2 in the floor drain body 1, so that the odor cannot flow back into the secondary drainage regulating pipe 3, and thus cannot flow out from the floor drain. This is a primary odor prevention. If there is no water in the floor drain body 1, the odor and sewage will flow back from the secondary drainage regulating pipe 3 and will be blocked by the floor drain shell 7 and the baffle plate 9. This is a secondary odor prevention and waterproofing at the same time, which prevents the odor from flowing out of the floor. The water will flow out of the drain, causing adverse effects. At the same time, when draining, the water flows through the deodorizing and waterproofing components, the secondary drainage guide plate 4, the secondary drainage regulating pipe 3, the floor drain inner core 2 and the floor drain body 1 in sequence, and is thus discharged. This is drainage in sequence. When the water does not enter the waterproofing and deodorizing components, but penetrates under the floor, the water falls in the secondary drainage guide plate 4 and is introduced into the secondary drainage regulating pipe 3 and is discharged again. This is secondary drainage to ensure the discharge of the water. When the floor drain body 1 is blocked, the floor drain shell 7, the V-shaped hair filter net 10 and the floor drain inner core 2 can be taken out, and then the floor drain body 1 can be dredged with tools or manually to facilitate cleaning and dredging.
