[0036] Example 1

[0037] A specific embodiment of the present invention is as follows Figures 1 to 8 As shown, a deodorizing floor drain is disclosed, comprising:

[0038] The first baffle system 4 and the second baffle system 5 are arranged on the drain pipe 9; wherein the first baffle system 4 is fixedly arranged on the drain pipe 9 and is provided with an upper water inlet 406 and a lower drain outlet 407. A water passage is provided between the upper water inlet 406 and the lower drain outlet 407. The upper water inlet 406 and the lower drain outlet 407 are both connected to the drain pipe 9, so that the water passage can form a part of the drain pipe 9; an inlet and outlet 408 are provided on the lateral side wall of the first baffle system 4;

[0039] The second baffle system 5 has a fixed part and a movable part. The fixed part of the second baffle system 5 is fixedly connected to the outer wall of the drain pipe 9. The movable part of the second baffle system 5 is sealingly slidably installed on the inlet and outlet 408 of the first baffle system 4. The side end face of the movable part can be sealedly contacted and separated from the side end face of the inner wall of the first baffle system 4 to achieve the connected and closed state of the water channel, and then achieve the connected and closed state of the drain pipe 9.

[0040] The bypass system 8 is configured to connect the first baffle system 4 with the drain pipe 9 above the upper water inlet 406 .

[0041] In this embodiment, the first baffle system 4 includes a first shell 405 and a first baffle assembly arranged in the first shell 405, the upper water inlet 406 is arranged on the top end surface of the first shell 405, and the lower drain outlet 407 is arranged on the bottom end surface of the first shell 405; the first baffle assembly includes a first movable plate 402 and a first fixed plate 403, the first fixed plate 403 is fixedly connected to the inner wall of the first shell 405, the first movable plate 402 is movably arranged in the first shell 405 and contacts the first fixed plate 403, the first movable plate 402 and the first fixed plate 403 can move relative to each other along the contact surface, the first movable plate 402 is provided with a first opening 4021, the first fixed plate 403 is provided with a second opening 4031 corresponding to the first opening 4021, the first movable plate 402 can move up and down so that the first opening 4021 and the second opening 4031 can be connected and staggered; the first fixed plate 403 constitutes part or all of the channel wall of the water channel. The first partition system has a connected state and a closed state. The connected state refers to the state when the first opening 4021 is connected to the second opening 4031. At this time, the first movable plate 402 and the first fixed plate 403 form a combined water leakage plate; the closed state refers to the state when the first opening 4021 and the second opening 4031 are completely staggered. At this time, the first movable plate 402 and the first fixed plate 403 form a first combined water barrier.

[0042] Optionally, the first movable plate 402 can move up and down. At this time, the height of the first movable plate 402 is less than the height of the first fixed plate 403. The height difference between the two can meet the longitudinal movement range of the first movable plate 402, while ensuring that the first opening 4021 and the second opening 4031 are directly connected and staggered.

[0043] The first partition system 4 further includes a first control unit 401 configured to control the movement of the first movable plate 402 to switch the first partition system between a connected state and a closed state.

[0044] A pressure sensor 404 is further provided inside the first baffle system 4 for monitoring the water pressure inside the first baffle system 4 and reflecting the amount of water by measuring the water pressure.

[0045] The first baffle system 4 is connected to the drain pipe 9 above via a bypass system 8. Specifically, the bypass system 8 includes a bypass pipe 804, a fourth control unit 801, a second telescopic rod 802, and a plug 803. A water inlet 4051 is provided on the top surface of the first housing 405. The interior of the first housing 405 contains a water storage space 4052, which is arranged around the first movable plate 402 and the first fixed plate 403. The water outlet of the bypass pipe 804 is connected to the water inlet 4051, which is in communication with the water storage space 4052 of the first housing 405.

[0046] When sewage passes through, the fourth control unit 801 controls the second telescopic rod 802 to rise, so that the plug 803 is separated from the water inlet of the bypass pipe 804, so that the sewage enters the first baffle system 4 through the bypass pipe 804; when no sewage passes through, the fourth control unit 801 controls the second telescopic rod to descend, so as to push the plug 803 to seal the water inlet of the bypass pipe 804, thereby preventing the evaporation of water in the first baffle system 4.

[0047] When the monitored pressure value is lower than the set risk threshold, it indicates that the partition system may not be able to meet normal needs, and the alarm and exhaust system will be activated. The alarm is used to remind people that the floor drain is broken and to repair it as soon as possible. At the same time, the activation of the exhaust system can also prevent the room from being filled with toxic and harmful gases, which will damage people's health.

[0048] In this embodiment, the second partition system 5 includes a second shell 513 and a second partition assembly disposed within the second shell 513. The second shell 513 has a retractable portion 512. The second partition assembly is connected to the retractable portion 512 of the second shell 513. The movable portion of the second partition system 5 includes the second partition assembly and the retractable portion 512 of the second shell 513.

[0049] The second partition assembly includes a second movable plate 502 and a second fixed plate 503. The second fixed plate 503 and the second movable plate 502 are in contact and can move relative to each other along the contact surface. The second movable plate 502 is provided with a third opening 5021, and the second fixed plate 503 is provided with a fourth opening 5031 corresponding to the third opening 5021. The second movable plate 502 can move up and down so that the third opening 5021 and the fourth opening 5031 can be connected and staggered. The second partition system has a connected state and a closed state. The connected state refers to the state when the third opening 5021 is connected to the fourth opening 5031, and the second movable plate 502 and the second fixed plate 503 form a combined water leakage plate; the closed state refers to the state when the third opening 5021 is completely staggered with the fourth opening 5031, and the second movable plate 502 and the second fixed plate 503 form a second combined water baffle; and the second combined water baffle can move laterally in the inlet and outlet 408 of the first partition system 4 as the retractable part 512 of the second shell 513 extends and shortens, so as to approach and move away from the first combined water baffle, thereby realizing the contact and separation of the second combined water baffle and the first combined water baffle.

[0050] Optionally, the second movable plate 502 can move up and down. At this time, the height of the second movable plate 502 is less than the height of the second fixed plate 503. The height difference between the two can meet the longitudinal movement range of the second movable plate 502, while ensuring that the third opening 5021 and the fourth opening 5031 are directly connected and staggered.

[0051] The second partition system 5 also includes a second control unit 501 and a fifth control unit 505. The second control unit 501 is configured to control the movement of the second movable plate 502 so that the second partition system switches between a connected state and a closed state. The fifth control unit 505 is configured to control the lateral movement of the first telescopic device 504 to achieve extrusion contact and separation of the second combined baffle of the second partition system 5 and the first combined baffle of the first partition system 4. The fifth control unit 505 is capable of controlling the contraction and expansion of the first telescopic device 504. Specifically, the first telescopic device 504 includes a telescopic rod, which is connected to the telescopic part 512 of the second shell 513. When the telescopic rod is contracted, the telescopic part 512 of the second shell 513 is changed to a contracted state. When the telescopic rod is extended, the telescopic part 512 of the second shell 513 is changed to an expanded state.

[0052] The second baffle system 5 further includes a ventilation system 511 , which is configured to adjust the air pressure in the second baffle system 5 .

[0053] Specifically, the ventilation system 511 includes a partition 506, a third control unit 507, a first telescopic rod 508, and a piston 509. The partition 506 is vertically arranged in the second shell 513 and forms a cavity with the inner wall of the second shell 513 for mounting the piston 509 and the first telescopic rod 508. The upper end of the first telescopic rod 508 is fixed to the top wall of the second shell 513. The piston 509 is arranged at the lower end of the first telescopic rod 508 and is in sealed sliding contact with the inner wall of the cavity. The cavity is connected to the space on the other side of the partition 506 to enable gas exchange. Optionally, there is a gap between the lower end of the partition 506 and the bottom wall of the second shell 513. This gap connects the space on both sides of the partition 506, enabling gas exchange between the gas in the cavity and the space on the other side of the partition. The third control unit 507 is configured to control the first telescopic rod 508 to drive the piston 509 to move up and down in the cavity to adjust the air pressure in the second partition system 5.

[0054] In one optional embodiment, the contact portion between the first separator system 4 and the second separator system 5 is made of rubber material.

[0055] In this embodiment, a bell mouth 6 is provided in the drain pipe 9, and the bell mouth 6 is located above the first baffle system 4 and the second baffle system 5, so that water flows into the drain pipe 9 through the bell mouth 6, avoiding the formation of wall flow and affecting the normal use of the first baffle system 4 and the second baffle system 5.

[0056] In this embodiment, a floor drain grille 3 is arranged in the drainage pipe 9, and a floor drain cover 2 is arranged above the floor drain grille 3. The floor drain cover 2 is flush with the ground 1. The floor drain grille 3 is located above the bell mouth 6. The center line of the floor drain grille 3 is biased towards the bypass pipe 804 compared to the center line of the bell mouth 6 to ensure that sewage can smoothly enter the first partition system 4 through the bypass pipe 804.

[0057] In this embodiment, the ventilation system 511 of the second partition system 5 is connected to the drain pipe 9 through the ventilation pipe 510. A ventilation hole 5131 is provided on the top surface of the second shell 513 of the second partition system 5. One end of the ventilation pipe 510 is connected to the ventilation hole 5131, and the other end is connected to the drain pipe 9; the upper port of the ventilation pipe 510 is connected to the bottom of the bell mouth 6, so that the air pressure balance inside the second partition system 5 can be maintained, and sewage can be ensured not to enter the ventilation pipe 510.

[0058] In this embodiment, a micro flow meter 7 is further provided within the drain pipe 9 and is located above the bell mouth 6. The micro flow meter 7 is configured to detect whether water is flowing through the drain pipe and transmit a signal indicating whether water is flowing through the drain pipe to a control system. The control system controls the operation of the floor drain structure based on the signal indicating whether water is flowing through the drain pipe. The control system includes a first control unit 401, a second control unit 501, a third control unit 507, a fourth control unit 801, and a fifth control unit 505.

[0059] In one optional embodiment, the end of the first partition system 4 facing the second partition system 5 is configured as a concave shape, and the second partition system 5 is configured as a convex shape to ensure sealing of the contact portion. For example, the first movable plate 402 and the first fixed plate 403 of the first partition system 4 are integrally U-shaped, and the second movable plate 502 and the second fixed plate 503 of the second partition system 5 are also integrally U-shaped.

[0060] In one of the optional embodiments, the connection between the lower drain outlet 407 of the first partition system 4 and the drain pipe 9 is arranged to be sloped, that is, the interior of the first shell 405 has a bearing plane 409, and the bearing plane 409 extends to the lower drain outlet 407 of the first partition system 4 through a slope surface 410. When the movable part of the second partition system 5 is installed into the inlet and outlet 408 of the first partition system 4, the lower surface of the movable part is in surface contact with the bearing plane 409, and the slope surface 410 is located obliquely below the movable part, which can prevent water from flowing into the installation place of the second partition system 5.

[0061] In one optional embodiment, the first fixing plate 403 and the second fixing plate 503 are made of rubber.

[0062] In one optional embodiment, the odor-proof floor drain can be provided with a power storage unit. In an emergency, when the original power supply is insufficient, the power storage unit continuously supplies power to the odor-proof floor drain to ensure stable operation of the floor drain system.

[0063] Case 1: When the odor-proof floor drain is used for the first time and there is no water flowing through it

[0064] In the initial state, the odor-proof floor drain is in a closed state. At this time, the micro flowmeter 7 detects that there is no water flowing through. The movable part of the second partition system 5 is located inside the first partition system 4. The first partition system 4 and the second partition system 5 are tightly connected. The movable part of the second partition system 5 blocks the water passage of the first partition system 4, thereby putting the odor-proof floor drain in a closed state.

[0065] The first baffle system 4 is in a connected state, while the second baffle system 5 is in a closed state. Specifically, the first opening 4021 on the first movable plate 402 is connected to the second opening 4031 on the first fixed plate 403, and the third opening 5021 on the second movable plate 502 is completely offset from the fourth opening 5031 on the second fixed plate 503.

[0066] By setting the holes on the two partition systems in different states, it can be achieved that when the two systems are in close contact and some water is located between them, the contact force between the two can be enhanced, making them more closely connected, so that the odor-proof floor drain is in a closed state.

[0067] Case 2: When water flows through

[0068] When the micro flowmeter 7 detects water flowing through, the fifth control unit 505 controls the movable part of the second partition system 5 to move away from the first partition system 4, and the movable part of the second partition system 5 is separated from the first partition system 4, and the water flow channel of the first partition system 4 is opened, so that the odor-proof floor drain is in an open state.

[0069] During this process, the second control unit 501 controls the movement of the second movable plate 502, causing the second baffle system 5 to transition from a closed state to an open state. The third control unit 507 controls the first telescopic rod 508 to drive the piston 509 downward, gradually increasing the air pressure in the ventilation system 511 of the second baffle system 5. The piston 509 then pushes air through the connected third opening 5021 and fourth opening 5031, into the space between the first baffle system 4 and the second baffle system 5. Simultaneously, the first control unit 401 controls the movement of the first movable plate 402, causing the first baffle system 4 to transition from an open state to a closed state, preventing water from entering the space between the first and second baffle systems 4, 5. The fifth control unit 505 controls the movement of the first telescopic device 504, separating the first and second baffle systems 4, 5 and opening the water passage of the first baffle system 4. Sewage generated indoors flows through the open water passage after the separation of the first and second baffle systems 4, 5, and into the drain pipe 9 below. After the two partition systems are separated, the piston 509 behind the second partition system 5 remains in the status quo to be restored.

[0070] Case 3: When the water flow stops

[0071] When the water flow stops, the micro flow meter 7 on the top of the first baffle system 4 cannot detect the passing of water, and the fifth control unit 505 controls the movable part of the second baffle system 5 to move toward the interior of the first baffle system 4. The movable part of the second baffle system 5 and the first baffle system 4 are squeezed to block the water flow channel of the first baffle system 4, so that the odor-proof floor drain is in a closed state.

[0072] During this process, the fifth control unit 505 controls the movement of the first telescopic device 504 so that the moving part of the second partition system 5 gradually approaches the interior of the first partition system 4 and generates extrusion. At the same time, the first control unit 401 controls the first movable plate 402 to move, so that the first partition system 4 changes from a closed state to a connected state. The third control unit 507 controls the first telescopic rod 508 to drive the piston 509 to move upward so that the piston 509 gradually returns to its initial state, and the second control unit 501 controls the second movable plate 502 to move, so that the second partition system 5 changes from a connected state to a closed state. In this way, a negative pressure state can be formed between the first partition system 4 and the second partition system 5, and the odor-proof floor drain can be sealed under the action of atmospheric pressure and the extrusion between the first partition system 4 and the second partition system 5, thereby preventing toxic and harmful gases and mosquitoes in the sewer from entering the room.

[0073] Case 4: When the odor-proof floor drain fails

[0074] During operation, the odor-resistant floor drain uses pressure sensor 404 to monitor the internal water pressure of the first baffle system 4, specifically the water pressure within the water storage space 4052. When the pressure detected by the pressure sensor falls below a set risk threshold, an alarm and ventilation system are activated. The alarm alerts the user to a faulty floor drain, prompting prompt repairs. Simultaneously, the ventilation system operates to promptly extract toxic and harmful gases from the room, preventing them from filling up and potentially harming human health.

[0075] Compared with the prior art, the deodorizing floor drain provided by the present embodiment forms a powerful floor drain sealing device through the combination of the first baffle system and the second baffle system, effectively preventing gas and mosquitoes in the sewer from entering the room, and is reliable in operation and has better safety and security. Since the contact parts of the first baffle system and the second baffle system have both been exposed to water, the principle that the contact between the two rubber materials that have been exposed to water is difficult to separate is utilized, and a powerful floor drain sealing device is formed by mechanized means, which changes the original arrangement of forming a water seal using an S-tube. The water in the water seal formed by the original S-bend pipe is easily destroyed by evaporation, and the water seal is easily destroyed when encountering emergencies such as earthquakes. In the present embodiment, the water in the first baffle system is not easily lost through mechanical control and the sealing control of the baffle system, thereby extending the service life of the floor drain. At the same time, the mechanical control makes the sealing and anti-interference performance of the device stronger. At the same time, gas, mosquitoes, mice, etc. in the sewer can also be prevented from entering the room.
