Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of building drainage, and particularly relates to an intelligent drainage system. BACKGROUND

[0002] The same-floor drainage technology is a novel technology in the building drainage system, drainage pipes are laid on the same floor of a building, and a common water seal pipe fitting is used to replace many P-bends and S-bends, the overall structure is reasonably designed, and is not prone to blockage, and is easy to clean and dredge. The same-floor drainage system mainly comprises a main pipe, a multi-channel joint, a branch pipe, a toilet inlet, a multifunctional floor drain, a multifunctional water-following tee joint and the like.

[0003] Generally, in the same-floor drainage pipe network of a building, drainage fittings such as floor drains and water traps are connected to a collector, and the collector is connected to a discharge riser of the building to complete the centralized discharge of indoor sewage. However, the water trap may cause odor to be emitted from the water trap due to insufficient water, and the floor drain or the collector may be blocked, resulting in failure of the drainage function and inability to normally drain water, thereby causing the problem of water backflow in the drainage system. When at least one drainage fitting of the drainage system fails, people need to carefully check one by one, which takes a long time and has high labor intensity, and is not conducive to improving the maintenance efficiency of the drainage system. SUMMARY

[0004] The present application aims to provide an intelligent drainage system with high intelligence, which can monitor the conditions of each drainage fitting in the drainage system in real time, and timely inform people of the failure of the drainage system, thereby saving the time for troubleshooting and improving the maintenance efficiency.

[0005] To solve the above technical problems, the technical scheme adopted by the present application is as follows:

[0006] The present application discloses an intelligent drainage system, comprising:

[0007] a collector having a water collecting cavity, the collector being provided with a first water level probe for detecting the water level of the water collecting cavity;

[0008] a floor drain having a drainage cavity, the outlet of the drainage cavity being communicated with the water collecting cavity, the floor drain being provided with a second water level probe for detecting the water level of the drainage cavity;

[0009] a water trap having a water storage cavity, the outlet of the water storage cavity being communicated with the water collecting cavity, the water trap being provided with a third water level probe for detecting the water level of the water storage cavity;

[0010] a water replenishing pipe being provided with an electric valve, the outlet of the water replenishing pipe being communicated with the water storage cavity;

[0011] an alarm;

[0012] a controller, the third water level probe and the electric valve are electrically connected with the controller respectively, the first water level probe and the alarm are electrically connected with the controller respectively, and the second water level probe and the alarm are electrically connected with the controller respectively.

[0013] The intelligent drainage system has at least the following beneficial effects: in the intelligent drainage system, sewage of floor drains and traps is all drained to the collector, so that the collector can be used for centralized drainage; if the trap has too little water, the third water level probe is triggered, the controller controls the electric valve to open, the replenishment pipeline supplies sufficient water to the water storage cavity, and the odor is prevented from overflowing from the trap; if the floor drain is blocked, the second water level probe is triggered, the controller controls the corresponding alarm to work, and the user is timely informed; if the collector is blocked, the first water level probe is triggered, the alarm is started under the action of the controller, and the user is timely informed; the intelligent drainage system is thus arranged, the conditions of various drainage accessories can be monitored in real time, the problem of insufficient water seal of the trap can be timely handled, and the fault drainage accessory in the drainage system can be informed, so that the maintenance efficiency is prevented from being reduced due to one-by-one troubleshooting.

[0014] As a further improvement of the above technical solution, the outlet of the water replenishment pipeline is connected with the inlet of the trap. Thus, the water replenishment pipeline can be prevented from being polluted by sewage in the water storage cavity, and the service life of the electric valve is prolonged.

[0015] As a further improvement of the above technical solution, the third water level probe is located at one end of the water storage cavity away from the inlet of the trap. Thus, when the trap is replenished with water, the third water level probe can be prevented from being triggered by mistake due to contact with flowing water.

[0016] As a further improvement of the above technical solution, the floor drain is provided with a first drainage pipe and a second drainage pipe, the bottom surface of the drainage cavity is provided with a first outlet, the side wall surface of the drainage cavity is provided with a second outlet, one end of the first drainage pipe is connected with the first outlet, the other end of the first drainage pipe is communicated with the water collecting cavity, one end of the second drainage pipe is connected with the second outlet, the other end of the second drainage pipe is communicated with the water collecting cavity, and the second drainage pipe is provided with a one-way valve, and the flow direction of the one-way valve is from the drainage cavity to the water collecting cavity.

[0017] When the floor drain is normally drained, the water in the drainage cavity is drained through the first outlet and the first drainage pipe; if the first outlet of the floor drain is blocked, the water in the drainage cavity is discharged through the second outlet and the second drainage pipe, avoiding the accumulation of too much water in the drainage cavity and the occurrence of water backflow; the one-way valve is opened when the second drainage pipe discharges water due to the impact of water; the one-way valve is closed when the first drainage pipe normally drains water, effectively isolating the odor of the second drainage pipe and preventing insects from crawling out of the second drainage pipe.

[0018] As a further improvement of the above technical solution, the other end of the second drainage pipe is connected to the other end of the first drainage pipe. By setting up in this way, the length of the second drainage pipe can be reduced, saving materials and costs, and the first drainage pipe and the second drainage pipe of the floor drain will only occupy one discharge inlet of the collector, enabling the collector to be connected to more drainage accessories.

[0019] As a further improvement of the above technical solution, the one-way valve comprises a housing and a valve plate; the housing is provided with a drainage hole, and the valve plate is located at the outlet of the drainage hole; the upper end of the valve plate is hinged to the housing, and the valve plate can block the outlet of the drainage hole.

[0020] By setting up in this way, when the second drainage pipe discharges water in the drainage cavity, the valve plate will swing upward under the impact of water, opening the outlet of the drainage hole, and water can flow into the second drainage pipe; after the second drainage pipe finishes discharging water, the valve plate will automatically swing downward due to its own gravity, blocking the outlet of the drainage hole, and preventing the odor in the second drainage pipe from being emitted from the drainage hole.

[0021] As a further improvement of the above technical solution, the one-way valve further comprises a first magnet and a second magnet; the first magnet is arranged at the upper part of the housing; the second magnet is located above the valve plate and connected to the upper end of the valve plate, and the same magnetic poles of the first magnet and the second magnet are close to each other. By setting up in this way, a certain magnetic repulsion occurs between the first magnet and the second magnet, allowing the valve plate to swing downward quickly and automatically under the dual action of magnetic force and gravity, and enabling the valve plate to tightly adhere to the housing, ensuring that the outlet of the drainage hole is completely closed to prevent backflow, thereby ensuring the cleanliness of the indoor space.

[0022] As a further improvement of the above technical solution, the bottom surface of the drainage cavity is inclined downward from top to bottom to the first outlet. By setting up in this way, the water in the drainage cavity can automatically flow downward to the first outlet due to gravity, so as to completely drain the water in the drainage cavity.

[0023] As a further improvement of the above technical solution, the floor drain comprises a floor drain cover and a floor drain shell, the floor drain cover is arranged on the floor drain shell, and the floor drain cover and the floor drain shell jointly form the drainage cavity. In this way, when the floor drain is blocked, the floor drain cover can be quickly disassembled to dredge the floor drain shell.

[0024] As a further improvement of the above technical solution, the second water level probe is detachably connected with the floor drain cover. In this way, when the second water level probe needs to be maintained and replaced due to failure, the second water level probe can be easily detached from the floor drain cover without affecting the use of the floor drain cover.

[0037] Reference Figures 1 to 5 , the intelligent drainage system of the present application will be described in several embodiments.

[0038] As Figures 1 to 5 shown, the embodiment one of the present application provides an intelligent drainage system, the structure of the intelligent drainage system includes a collector 100, a floor drain 400, a water trap 200, a water replenishment pipeline 310, an alarm and a controller, which has high intelligence, can monitor the condition of each drainage accessory in the drainage system in real time, and timely inform people of the fault of the drainage system, save the time of troubleshooting, and thus improve the maintenance efficiency. The intelligent drainage system can be used as a same-floor drainage system.

[0039] Among them, the alarm can be a sound alarm, a sound and light alarm, etc., which is not limited here. The controller can be a single-chip microcomputer, a PLC controller, an integrated circuit board, etc., which is not limited here.

[0040] The collector 100 has a water collection chamber formed in its central part. The collector 100 is provided with a discharge inlet 101 and a discharge outlet 102, both of which are connected to the water collection chamber. In this embodiment, both ends of the collector 100 extend vertically. There are three discharge inlets 101 located on the outer periphery of the collector 100 for connection to drainage fittings such as floor drains 400 and water traps 200. There is one discharge outlet 102 located below the discharge inlets 101 on the outer periphery of the collector 100, and it can be connected to the building's drainage riser via a pipe. However, the number of discharge inlets 101 is not limited to three.

[0041] The collector 100 is equipped with a first water level probe 110, which is used to detect the water level in the collection chamber. The first water level probe 110 and the alarm are electrically connected to the controller, so that the controller can intelligently control the alarm to work after receiving the detection electrical signal from the first water level probe 110.

[0042] In this embodiment, the first water level probe 110 extends horizontally and is installed on the outer peripheral surface of the collector 100. Specifically, the outer peripheral wall of the collector 100 is provided with a mounting hole, and the first water level probe 110 can be located at the mounting hole of the collector 100. The position of the first water level probe 110 is higher than the position of the discharge inlet 101.

[0043] like Figure 2 As shown, when the collector 100 is draining normally, the water level in the collection chamber is generally maintained at the normal water level line 103. When the water in the collection chamber cannot flow into the discharge riser normally, the water level in the collection chamber will continue to rise. When the first water level probe 110 is submerged in water, the two electrodes of the first water level probe 110 are made to conduct to each other, so that the first water level probe 110 generates a detection electrical signal.

[0044] The floor drain 400 has a hollow interior forming a drainage chamber 402, and the outlet of the drainage chamber 402 is connected to the water collection chamber. Specifically, the structure of the floor drain 400 includes a floor drain shell and a floor drain 400 cover. The floor drain shell has a groove with the opening of the groove facing upwards. The floor drain 400 cover fits onto the floor drain shell and can cover the opening of the groove, so that the floor drain shell and the floor drain 400 cover together form a drainage chamber 402.

[0045] The drain cover 400 has water inlet holes 401 that penetrate both the upper and lower surfaces of the drain cover and connect to the drainage chamber 402, allowing water from the floor to flow into the drainage chamber 402. The water inlet holes 401 can be round or elongated. Multiple water inlet holes 401 are arranged in an array.

[0046] In some embodiments, the floor drain 400 cover can be fixed on the floor drain shell by screws. In other embodiments, the floor drain 400 cover can be directly embedded into the floor drain shell from top to bottom. In this way, when the floor drain 400 is blocked, the floor drain 400 cover can be lifted upwards, allowing the floor drain 400 cover to be quickly disassembled to dredge the floor drain shell.

[0047] The upper surface of the floor drain 400 cover is flush with the upper surface of the floor drain shell. The shape of the floor drain 400 is not limited and can be cylindrical or cuboid.

[0048] The floor drain 400 is provided with a first outlet 403 and a first drain pipe 410. Specifically, the bottom surface of the drain cavity 402 is provided with a first outlet 403, which can be circular. The first outlet 403 can be located at the center of the bottom surface of the drain cavity 402.

[0049] In some embodiments, the bottom surface of the drain cavity 402 is planar. In other embodiments, the bottom surface of the drain cavity 402 is inclined, specifically, the bottom surface of the drain cavity 402 is inclined downward from top to bottom towards the first outlet 403. In this way, water in the drain cavity 402 will automatically flow downward due to its own gravity and flow towards the first outlet 403, so as to completely drain the water in the drain cavity 402, thereby avoiding the accumulation of water in the drain cavity 402.

[0050] One end of the first drain pipe 410 is connected to the first outlet 403 of the floor drain 400, and the other end of the first drain pipe 410 is connected to the water collecting cavity. Specifically, the first drain pipe 410 has two ends, one end is an inlet end, and the other end is an outlet end. In this embodiment, the opening of the inlet end is upwardly arranged, and the inlet end can be connected to the first outlet 403 by fusion or threaded connection. The opening of the outlet end is horizontally arranged and can be connected to one of the discharge inlets 101 of the collector 100, so as to enable the water in the drain cavity 402 to be discharged to the water collecting cavity through the first drain pipe 410.

[0051] The first drain pipe 410 can be arranged horizontally or inclined, specifically, the first drain pipe 410 is inclined downward from top to bottom towards the collector 100.

[0052] The floor drain 400 is provided with a second water level probe 430 for detecting the water level of the drain cavity 402. The second water level probe 430 and the alarm are respectively electrically connected to the controller by cables, so that the second water level probe 430 can transmit the detection electrical signal generated thereby to the controller, and the controller generates a control instruction and sends it to the alarm to make the alarm work.

[0053] It can be understood that the alarm can be arranged for the first water level probe 110 and the second water level probe 430 respectively; of course, the alarm can be shared by the first water level probe 110 and the second water level probe 430, and the alarm has two indicator lights corresponding to the first water level probe 110 and the second water level probe 430 respectively, so as to clearly indicate which of the collector 100 and the floor drain 400 is blocked.

[0054] In the embodiment, the second water level probe 430 is arranged along the up and down directions and is installed on the cover of the floor drain 400. The second water level probe 430 can extend downward to the drainage cavity 402, and the detection end of the second water level probe 430 (i.e. the electrode of the second water level probe 430) has a certain height distance from the bottom surface of the drainage cavity 402, which can be set according to actual conditions.

[0055] When the hair and other silk fabrics are accumulated for a long time and block the first outlet 403 of the floor drain 400, the first drain pipe 410 cannot normally drain water, and the water in the drainage cavity 402 continuously accumulates, so that the water level of the drainage cavity 402 continuously rises, thereby promoting the two electrodes of the second water level probe 430 to be mutually conducted. At this time, the second water level probe 430 generates a detection electric signal.

[0056] The second water level probe 430 can be detachably connected to the cover of the floor drain 400. Specifically, the cover of the floor drain 400 is provided with a mounting step hole, and the second water level probe 430 can be inserted downward into the mounting step hole, so that the second water level probe 430 can be stably fixed on the cover of the floor drain 400. When the second water level probe 430 needs to be maintained and replaced due to failure, the second water level probe 430 can be quickly removed from the cover of the floor drain 400, without affecting the use of the cover of the floor drain 400 and without replacing the cover of the floor drain 400.

[0057] Of course, the second water level probe 430 can also be fixed on the cover of the floor drain 400 by screws.

[0058] The water storage bend 200 is internally hollow to form a water storage cavity, and the outlet of the water storage cavity is communicated with the water collecting cavity. It can be understood that the water storage bend 200 can be a P-shaped water storage bend or an S-shaped water storage bend. For example, Figure 1 and Figure 3As shown, in the present embodiment, the water trap 200 is S-shaped, and has a water inlet 201 and a drain outlet 202, both of which are communicated with the water storage cavity. The opening of the water inlet 201 is upwardly arranged, and the opening of the drain outlet 202 is downwardly arranged. The drain outlet 202 is the outlet of the water storage cavity, and the water inlet 201 is the inlet of the water storage cavity. The water inlet 201 of the water trap 200 can be connected to the drain pipe of the sink, basin, etc. through a pipeline, a pipe joint, etc. to realize the drainage of the sink, basin, etc. The drain outlet 202 of the water trap 200 is connected to one of the drain inlets 101 of the collector 100 through a connecting pipeline 220.

[0059] It can be understood that the number of water traps 200 and the number of floor drains 400 are not limited to one, and the collector 100 can be connected to multiple water traps 200 and multiple floor drains 400.

[0060] The water trap 200 is provided with a third water level probe 210 for detecting the water level of the water storage cavity. In the present embodiment, the water trap 200 is provided with a mounting hole, and the third water level probe 210 extends in the horizontal direction and is arranged in the mounting hole of the water trap 200.

[0061] When the water level in the water storage cavity is too low, the third water level probe 210 is not submerged, causing the detection electrical signal of the third water level probe 210 to disappear. At this time, it can be indicated that the water amount of the water storage cavity is insufficient, and water needs to be replenished. When the water level in the water storage cavity reaches a certain height, the third water level probe 210 will be submerged, the two electrodes of the third water level probe 210 are in conduction, and the third water level probe 210 generates a detection electrical signal. At this time, water replenishment is not required.

[0062] The water replenishment pipeline 310 is provided with an electric valve 320, which can be an electric ball valve, without limitation. By controlling the action of the electric valve 320, the on-off of the water replenishment pipeline 310 can be controlled. The electric valve 320 and the third water level probe 210 are respectively electrically connected to the controller through cables, so that the controller can receive the detection electrical signal of the third water level probe 210 to control the opening and closing action of the electric valve 320.

[0063] The water replenishment pipeline 310 has an inlet and an outlet. The inlet of the water replenishment pipeline 310 can be connected in parallel to the drain pipe of the sink, basin, etc. through a pipe joint, or connected to the indoor water supply pipe. The outlet of the water replenishment pipeline 310 is connected to the water trap 200 through a pipe joint, so that the outlet of the water replenishment pipeline 310 is communicated with the water storage cavity, and the water in the water replenishment pipeline 310 flows to the water storage cavity to replenish the water trap 200, avoiding the problem that the water seal performance of the water trap 200 is insufficient due to insufficient water storage, causing the odor to spread from the water trap 200.

[0064] In the embodiment, the outlet of the water replenishing pipeline 310 is connected to the inlet of the water trap 200 vertically, so that the position of the outlet of the water replenishing pipeline 310 is higher than the position of the water trap, which can avoid the water replenishing pipeline 310 from being polluted by the waste water 500 in the water trap, prolong the service life of the electric valve 320, and reduce the resistance at the outlet of the water replenishing pipeline 310, so that the water in the water replenishing pipeline 310 can flow into the water trap due to gravity, and prevent the waste water 500 in the water trap from flowing back to the water replenishing pipeline 310.

[0065] In some embodiments, the third water level probe 210 is arranged at one end of the water trap close to the inlet of the water trap. In other embodiments, the third water level probe 210 is arranged at one end of the water trap away from the inlet of the water trap, so as to avoid the third water level probe 210 from being triggered by the flowing water and causing the intelligent drainage system to mistakenly believe that there is no need to replenish water.

[0066] In some embodiments, a lowest water level line 204 and a highest water level line 203 are arranged in the water trap. The mounting hole of the water trap 200 is arranged between the lowest water level line 204 and the highest water level line 203. The third water level probe 210 can be provided with two, which are arranged separately in the up-down direction. The upper third water level probe 210 is used to detect whether the water level in the water trap reaches the highest water level line 203, and the lower third water level probe 210 is used to detect whether the water level in the water trap reaches the lowest water level line 204.

[0067] When the water level in the water trap reaches the lowest water level line 204, the two electrodes of the lower third water level probe 210 are disconnected due to the lack of water conduction, the detection electric signal generated by the lower third water level probe 210 disappears, and then the controller controls the electric valve 320 to open, so that the water in the water replenishing pipeline 310 flows into the water trap. During the water replenishing process, when the water level in the water trap reaches the highest water level line 203, the two electrodes of the upper third water level probe 210 are connected due to the water conduction, the detection electric signal generated by the upper third water level probe 210 disappears, and then the controller controls the electric valve 320 to close and stops the water replenishing.

[0068] It can be understood that in the intelligent drainage system provided in the embodiment, if the water trap 200 has too little water, the third water level probe 210 will be triggered, the controller will control the electric valve 320 to open, and the water replenishing pipeline will replenish enough water to the water trap to prevent odor from overflowing from the water trap 200; if the floor drain 400 is blocked, the second water level probe 430 will be triggered, the controller will control the corresponding alarm to work to timely inform the user; if the collector 100 is blocked, the first water level probe 110 will be triggered, the alarm will be started under the action of the controller and will timely inform the user.

[0069] The intelligent drainage system is thus arranged to monitor the conditions of each drainage fitting in real time, and to timely handle the problem of insufficient water seal of the water trap 200 and to inform the faulty drainage fitting in the drainage system, thereby avoiding the decrease of maintenance efficiency caused by checking the faults one by one.

[0070] In some embodiments, the floor drain 400 is provided with a second drainage pipe 420, which is provided with a one-way valve 440.

[0071] When the floor drain 400 is blocked, the second water level probe 430 is triggered to control the alarm to work, and the wastewater 500 in the drainage cavity 402 can be discharged through the second drainage pipe 420 to avoid the backflow of the wastewater 500 due to the high water level in the drainage cavity 402.

[0072] The side wall of the drainage cavity 402 is provided with a second outlet, which can be higher than the first outlet 403, so that the water in the drainage cavity 402 can flow out from the second outlet when the water level reaches a certain height. The second outlet can be circular. One end of the second drainage pipe 420 is connected to the second outlet, and the other end of the second drainage pipe 420 is connected to the water collecting cavity, so that the water in the drainage cavity 402 can flow into the water collecting cavity through the second drainage pipe 420.

[0073] In some embodiments, the second drainage pipe 420 and the first drainage pipe 410 are independently arranged and connected to the discharge inlet 101 of the collector 100, respectively.

[0074] In other embodiments, the other end of the second drainage pipe 420 is connected to the other end of the first drainage pipe 410, which can reduce the length of the second drainage pipe 420, save materials and costs, and only one discharge inlet 101 of the collector 100 is occupied by the first drainage pipe 410 and the second drainage pipe 420 of the floor drain 400, which facilitates the connection of the collector 100 with more drainage fittings. In some embodiments, the discharge port 411 of the first drainage pipe 410 is vertically connected to the discharge inlet 101 of the collector 100.

[0075] The flow direction of the one-way valve 440 is from the drainage cavity 402 to the water collecting cavity, so that the water in the water collecting cavity cannot flow back to the second drainage pipe 420.

[0076] In some embodiments, the one-way valve 440 can be an existing one-way valve, and the water in the drainage cavity 402 can overcome the spring action of the one-way valve to open the one-way valve, so that the water in the drainage cavity 402 can flow into the second drainage pipe 420.

[0077] In other embodiments, the one-way valve 440 can be a check valve, and the water in the drainage cavity 402 can overcome the spring action of the check valve to open the check valve, so that the water in the drainage cavity 402 can flow into the second drainage pipe 420. Figure 4 and Figure 5As shown, the one-way valve 440 includes a valve plate 443 and a housing 441.

[0078] The housing 441 is provided with a drain hole 442, the axis of which extends horizontally. In this embodiment, a one-way valve 440 is located at the second outlet and connected to the second drain. The axial direction of the drain hole 442 is aligned with the axial direction of the second outlet. The opening of the drain hole 442 near the drain chamber 402 is the inlet, and the opening away from the drain chamber 402 is the outlet. A valve plate 443 is located at the outlet of the drain hole 442. The upper end of the valve plate 443 is hinged to the housing 441 via a hinge shaft, allowing the valve plate 443 to block the outlet of the drain hole 442.

[0079] When the valve plate 443 swings upward relative to the housing 441, the outlet of the drain hole 442 is open, allowing water in the drain chamber 402 to flow through the drain hole 442 to the second drain pipe 420. When the valve plate 443 swings downward relative to the housing 441 and comes into contact with the housing 441, the outlet of the drain hole 442 is closed, preventing odors, insects, and wastewater 500 from entering the drain chamber 402 of the floor drain 400.

[0080] Understandably, with the above-described structure, when the second drain pipe 420 discharges water from the drain chamber 402, the valve plate 443 will swing upward due to the impact of the water, opening the outlet of the drain hole 442 and allowing water to flow into the second drain pipe 420. After the second drain pipe 420 has finished draining, the valve plate 443 will automatically swing downward due to its own weight, blocking the outlet of the drain hole 442. At this time, the valve plate 443 is in a vertical state, thus preventing odors from the second drain pipe 420 from escaping from the drain hole 442.

[0081] Moreover, the center of gravity of the valve plate 443 is lower than the lowest point of the housing 441. According to the lever principle, the water located at the lowest point of the housing 441 can easily push the valve plate 443 and flow into the second drain pipe 420 through the drain hole 442. At the same time, it can avoid the problem of spring rusting and aging that is common in existing one-way valves.

[0082] Furthermore, such as Figure 5 As shown, the one-way valve 440 also includes a first magnet 444 and a second magnet 445.

[0083] The first magnet 444 is disposed on the upper part of the housing 441. Specifically, the upper surface of the housing 441 has a recessed receiving groove with an upward opening, and the first magnet 444 can be fixed in the receiving groove with glue.

[0084] The second magnet 445 is arranged above the valve plate 443, and the second magnet 445 is fixedly connected with the upper end of the valve plate 443. Specifically, the upper end of the valve plate 443 is provided with a connecting shell 446, and the connecting shell 446 can be integrally formed with the valve plate 443. The connecting shell 446 is provided with a receiving groove, and the second magnet 445 can be fixed in the receiving groove by glue, screws or the like.

[0085] The first magnet 444 and the second magnet 445 have the same magnetic poles at the ends close to each other.

[0086] When the valve plate 443 swings upward to the horizontal state, the opening of the receiving groove is opposite to the opening of the receiving groove, at this time, the second magnet 445 is located directly above the first magnet 444, and the lower end of the second magnet 445 is N pole, and the upper end of the first magnet 444 is N pole; if the lower end of the second magnet 445 is S pole, then the upper end of the first magnet 444 is S pole.

[0087] It can be understood that a certain magnetic repulsion action is generated between the first magnet 444 and the second magnet 445, so that the valve plate 443 can quickly and automatically swing downward under the dual action of magnetic force and gravity, and the valve plate 443 can be tightly attached to the shell 441, so as to ensure that the outlet of the drainage hole 442 is completely closed, to prevent backflow, thereby ensuring the hygiene of the indoor space. The first magnet 444 and the second magnet 445 are permanent magnets.

[0088] Further, the shell 441 can be provided with a rubber ring located at the outlet of the drainage hole 442. Specifically, the shell 441 is provided with an annular groove, and the rubber ring is embedded in the annular groove. The rubber ring surrounds the outlet of the drainage hole 442. When the valve plate 443 abuts against the shell 441 and blocks the outlet of the drainage hole 442, the valve plate 443 will abut against the rubber ring, causing the rubber ring to deform and effectively filling the small gap between the valve plate 443 and the shell 441, thereby enhancing the sealing effect and preventing the odor from being emitted to the floor drain 400 through the small gap.

[0089] It can be understood that the collector 100, the water trap 200, the floor drain 400 and the related pipelines can be made of plastic. The first water level probe 110, the second water level probe 430 and the third water level probe 210 are made of corrosion-resistant conductive materials.

[0090] The preferred embodiments of the application are specifically described above, but the application is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the application, and these equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
