The first water level probe 110 is located higher than the discharge inlet 101.

As shown in fig. 2, when the header 100 is normally drained, the water level in the water collection chamber is generally maintained at a normal water line 103. When the water in the water collecting cavity cannot normally flow into the discharge vertical pipe, the water level in the water collecting cavity can continuously rise, and when the first water level probe 110 is immersed by the water, the two electrodes of the first water level probe 110 are mutually conducted, so that the first water level probe 110 generates a detection electric signal.

The floor drain 400 is hollow and provided with a drainage cavity 402, and the outlet of the drainage cavity 402 is communicated with a water collecting cavity. Specifically, the floor drain 400 includes a floor drain housing and a floor drain 400 cover. The floor drain shell is provided with a groove, the opening of the groove is upwards arranged, the floor drain 400 cover is covered with the floor drain shell, and can cover the opening of the groove, so that the floor drain shell and the floor drain 400 cover jointly enclose a drain cavity 402.

The floor drain 400 cover is provided with water inlet holes 401, and the water inlet holes 401 respectively penetrate through the upper surface and the lower surface of the floor drain 400 cover and are communicated with the water discharge cavity 402, so that water on the ground can flow into the water discharge cavity 402 through the water inlet holes 401. It is understood that the water inlet 401 may be a circular hole or an elongated hole. The number of the water inlets 401 is a plurality, and the water inlets are arranged in an array mode.

In some embodiments, the floor drain 400 cover may be secured to the floor drain housing by screws. In other embodiments, the floor drain 400 cover can be directly embedded into the floor drain shell from top to bottom, so that when the floor drain 400 is blocked, the floor drain 400 cover can be lifted upwards, and the floor drain 400 cover can be quickly detached so as to dredge the floor drain shell.

The upper surface of the floor drain 400 cover is flush with the upper surface of the floor drain housing. The shape of the floor drain 400 is not limited, and may be a cylindrical shape, a rectangular parallelepiped shape, or the like.

The floor drain 400 is provided with a first outlet 403 and a first drain pipe 410. Specifically, the bottom surface of the drainage cavity 402 is provided with a first outlet 403, and the first outlet 403 may be circular. The first outlet 403 may be located at a central position of the bottom surface of the drainage cavity 402.

In some embodiments, the bottom surface of the drainage cavity 402 is planar. In other embodiments, the bottom surface of the drainage cavity 402 is inclined, and in particular, the bottom surface of the drainage cavity 402 is inclined from top to bottom to the first outlet 403, so that water in the drainage cavity 402 automatically flows down due to the gravity of the water and flows to the first outlet 403, so that water in the drainage cavity 402 is drained away, and accumulated water in the drainage cavity 402 can be avoided.

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 communicated with the water collecting cavity. Specifically, the first drain pipe 410 has two ends, one of which is an inlet end and the other of which is an outlet end, and in this embodiment, the opening of the inlet end is upward, and the inlet end may be connected to the first outlet 403 by welding or screwing, and the opening of the outlet end is horizontally disposed, and may be connected to one of the discharge inlets 101 of the header 100, so that water in the drain cavity 402 may be discharged to the water collecting cavity through the first drain pipe 410.

The first drain pipe 410 may be disposed horizontally, or may be disposed obliquely, and specifically, the first drain pipe 410 is inclined from top to bottom toward the header 100.

The floor drain 400 is provided with a second water level probe 430, the second water level probe 430 being used to detect the water level of the drainage cavity 402. The second water level probe 430 and the alarm are respectively and electrically connected to the controller through cables, so that the second water level probe 430 can transmit the detection electric signals generated by the second water level probe to the controller, and the controller generates control instructions and sends the control instructions to the alarm to enable the alarm to work.

It is understood that alarms may be provided for the first and second water level probes 110 and 430, respectively; of course, it is also possible to share an alarm for the first water level probe 110 and the second water level probe 430, which has two indicator lamps corresponding to the first water level probe 110 and the second water level probe 430, respectively, to clearly indicate which of the collector 100 and the floor drain 400 is clogged.

In this embodiment, the second water level probe 430 is provided to extend up and down and is mounted on the floor drain 400 cover. The second water level probe 430 can extend downward to the drain cavity 402, and a certain height distance is provided between the detection end of the second water level probe 430 (i.e., the electrode of the second water level probe 430) and the bottom surface of the drain cavity 402, and the height distance can be set according to practical situations.

When the silk fabric such as hair accumulates for a long time and blocks the first outlet 403 of the floor drain 400, the first drain pipe 410 cannot drain normally, so that the water in the drain cavity 402 is continuously accumulated, the water level in the drain cavity 402 is continuously increased, and the two electrodes of the second water level probe 430 are further caused to be conducted, and at this time, the second water level probe 430 generates a detection electric signal.

The second water level probe 430 is detachably connected to the floor drain 400 cover. Specifically, the floor drain 400 cover is provided with a mounting stepped hole, and the second water level probe 430 can be inserted downward into the mounting stepped hole, so that the second water level probe 430 can be stably fixed on the floor drain 400 cover. When the second water level probe 430 fails and needs maintenance and replacement, people can quickly detach the second water level probe 430 from the floor drain 400 cover without affecting the use of the floor drain 400 cover and without replacing the floor drain 400 cover.

Of course, the second water level probe 430 may be fixed to the floor drain 400 cover by screws.

The trap 200 is hollow to form a water storage cavity, and the outlet of the water storage cavity is communicated with the water collection cavity. It is understood that the trap 200 may be a P-type trap or an S-type trap. As shown in fig. 1 and 3, in this embodiment, the trap 200 is S-shaped, the trap 200 has a water inlet 201 and a water outlet 202, the water inlet 201 and the water outlet 202 are both connected to the water storage cavity, the opening of the water inlet 201 is upward, the opening of the water outlet 202 is downward, the water 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 trap 200 may be connected to a drain pipe of a sink, a basin, etc. through a pipe, a pipe joint, etc. to achieve drainage of the sink, basin, etc. The drain opening 202 of the trap 200 is connected to one of the drain inlets 101 of the header 100 by a connecting pipe 220.

It will be appreciated that the number of traps 200 and the number of floor drains 400 is not limited to one, and that the collector 100 may be connected to a plurality of traps 200, a plurality of floor drains 400.

The trap 200 is provided with a third water level probe 210, and the third water level probe 210 is used to detect the water level of the water storage chamber. In the present embodiment, the trap 200 is provided with a mounting hole, and the third water level probe 210 extends in a horizontal direction and is provided at the mounting hole of the trap 200.

When the water level in the water storage cavity is too low, the third water level probe 210 is not immersed, so that the detection electric signal of the third water level probe 210 is prompted to disappear, and at this time, the water shortage of the water storage cavity can be indicated, 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 is immersed, the two electrodes of the third water level probe 210 are communicated, the third water level probe 210 generates a detection electric signal, and water supplementing is not needed at this time.

The water replenishing pipe 310 is provided with an electric valve 320, and the electric valve 320 may be an electric ball valve, which is not limited herein. By controlling the operation of the electric valve 320, the on/off of the water replenishment pipe 310 can be controlled. The electric valve 320 and the third water level probe 210 are respectively electrically connected with the controller through cables, so that the controller can receive the detection electric signal of the third water level probe 210 to control the opening and closing actions of the electric valve 320.

The water supplementing pipeline 310 is provided with an inlet and an outlet, the inlet of the water supplementing pipeline 310 can be connected with a water tank, a basin and other discharge pipes in parallel through a pipe joint, or connected with an indoor water supply pipe, and the outlet of the water supplementing pipeline 310 is connected with the water storage bend 200 through a pipe joint, so that the outlet of the water supplementing pipeline 310 is communicated with the water storage cavity, water in the water supplementing pipeline 310 flows to the water storage cavity to supplement water for the water storage bend 200, and the problem that the water sealing performance of the water storage bend 200 is insufficient due to too little water storage capacity, and odor diffuses from the water storage bend 200 is avoided.

In this embodiment, the outlet of the water replenishing pipe 310 is vertically connected to the inlet of the water trap 200, so that the position of the outlet of the water replenishing pipe 310 is higher than that of the water storing cavity, which can prevent the water replenishing pipe 310 from being polluted by the waste water 500 in the water storing cavity, thereby being beneficial to prolonging the service life of the electric valve 320, and reducing the resistance of the outlet of the water replenishing pipe 310, so that the water in the water replenishing pipe 310 can flow into the water storing cavity due to the action of gravity, and the waste water 500 in the water storing cavity is prevented from flowing back to the water replenishing pipe 310.

In some embodiments, the third water level probe 210 is disposed at an end of the water storage chamber near the inlet of the water storage chamber. In other embodiments, the third water level probe 210 is disposed at an end of the water storage chamber away from the inlet of the trap 200, so as to avoid the situation that the third water level probe 210 is triggered by contact with the flowing water, which results in that the intelligent drainage system erroneously considers that no water replenishment is needed.

In some embodiments, in the water storage chamber, a lowest water line 204 and a highest water line 203 are provided. The mounting hole of the trap 200 is provided between the lowest water line 204 and the highest water line 203. The third water level probes 210 may be provided with two water level probes, and are spaced apart from each other in the vertical direction, the third water level probe 210 located above is used for detecting whether the water level in the water storage cavity reaches the highest water level line 203, and the third water level probe 210 located below is used for detecting whether the water level in the water storage cavity reaches the lowest water level line 204.

When the water level in the water storage chamber reaches the lowest water level line 204, the two electrodes of the third water level probe 210 positioned below are disconnected due to the lack of the conduction effect of water, and the detection electric signal generated by the third water level probe 210 positioned below disappears, so that the controller controls the electric valve 320 to open, and the water in the water supplementing pipeline 310 flows into the water storage chamber. In the water replenishing process, when the water level in the water storage cavity reaches the highest water level line 203, the two electrodes of the third water level probe 210 located above are turned on due to the conduction of water, and the third water level probe 210 located above generates a detection electric signal, so that the controller can control the electric valve 320 to be closed to stop replenishing water.

It can be understood that in the intelligent drainage system provided in this embodiment, if the trap 200 has too little water storage, the third water level probe 210 will be triggered, and the controller will control the electric valve 320 to open, so that the supplementing pipeline supplements the water storage cavity with enough water to prevent the odor from overflowing from the trap 200; if the floor drain 400 is blocked, the second water level probe 430 is triggered, and the controller controls the corresponding alarm to work to inform the user in time; if the collector 100 is blocked, the first water level probe 110 is triggered, and the alarm is activated under the action of the controller to inform the user in time.

The intelligent drainage system is arranged in such a way, the condition of each drainage fitting can be monitored in real time, the problem of insufficient water seal of the water trap 200 can be timely processed, and the fault drainage fittings in the drainage system can be informed, so that the problem that people check faults one by one to cause the reduction of maintenance efficiency is avoided.

In some embodiments, the floor drain 400 is provided with a second drain pipe 420, the second drain pipe 420 being provided with a one-way valve 440.

When the floor drain 400 is blocked, the second water level probe 430 is triggered to enable the controller to control the alarm to work, and meanwhile, the waste water 500 in the drainage cavity 402 can be discharged through the second drain pipe 420, so that the waste water 500 is prevented from flowing backwards due to the fact that the water level in the drainage cavity 402 is too high.

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

In some embodiments, the second drain pipe 420 and the first drain pipe 410 are provided independently of each other and are connected to the drain inlet 101 of the header 100, respectively.

In other embodiments, the other end of the second drain pipe 420 is connected to the other end of the first drain pipe 410, so that the length of the second drain pipe 420 can be reduced, and materials and costs can be saved, and the first drain pipe 410 and the second drain pipe 420 of the floor drain 400 occupy only one drain inlet 101 of the collector 100, so that the collector 100 can be connected with more drain fittings. The discharge opening 411 of the first drain pipe 410 is vertically connected to the discharge inlet 101 of the header 100.

The flow direction of the check valve 440 is from the drainage chamber 402 to the water collecting chamber, so that the water in the water collecting chamber does not flow back to the second drainage pipe 420.

In some embodiments, the check valve 440 may be an existing check valve, and the water in the drain cavity 402 overcomes the spring action of the check valve to open the check valve, allowing the water in the drain cavity 402 to flow into the second drain pipe 420.

In other embodiments, as shown in fig. 4 and 5, the structure of the check valve 440 includes a valve plate 443 and a housing 441.

The housing 441 is provided with a drain through hole 442, and an axis of the drain through hole 442 extends in a horizontal direction. In this embodiment, the check valve 440 is disposed at the second outlet and connected to the second drain, and the axial direction of the drain through hole 442 coincides with the axial direction of the second outlet. The opening of the drainage through hole 442, which is close to the drainage cavity 402, is an inlet, the opening of the drainage through hole 442, which is far away from the drainage cavity 402, is an outlet, the valve plate 443 is arranged at the outlet of the drainage through hole 442, and the upper end of the valve plate 443 is hinged to the shell 441 through a hinge shaft, so that the valve plate 443 can shield the outlet of the drainage through hole 442.

When the valve plate 443 swings upward with respect to the housing 441, the outlet of the drain through hole 442 is opened, so that water in the drain chamber 402 flows to the second drain pipe 420 through the drain through hole 442. When the valve plate 443 swings downward relative to the housing 441 and abuts against the housing 441, the outlet of the drain through hole 442 is closed, so that the odor, insects and wastewater 500 in the second drain pipe 420 cannot enter the drain cavity 402 of the floor drain 400.

It can be appreciated that the one-way valve 440 is configured as described above, when the second drain pipe 420 discharges the water in the drain cavity 402, the valve plate 443 swings upward under the impact of the water, so that the outlet of the drain through hole 442 is opened, and the water can flow into the second drain pipe 420; after the second drain pipe 420 is drained, the valve plate 443 automatically swings downward due to the gravity of the valve plate 443, and the outlet of the drain through hole 442 is blocked, at this time, the valve plate 443 is in a vertical state, so that the odor in the second drain pipe 420 can be prevented from being emitted from the drain through hole 442.

In addition, the center of gravity of the valve plate 443 is lower than the lowest position of the housing 441, so that water at the lowest position of the housing 441 can easily push the valve plate 443 according to the lever principle and flow into the second drain pipe 420 through the drain through hole 442, and meanwhile, the problem that the existing check valve is easy to rust and age due to the spring can be avoided.

Further, as shown in fig. 5, the structure of the check valve 440 further includes a first magnet 444 and a second magnet 445.

The first magnet 444 is disposed at an upper portion of the housing 441. Specifically, the upper surface of the housing 441 is concavely formed with an accommodating groove having an opening facing upward, and the first magnet 444 may be fixed in the accommodating groove by glue.

The second magnet 445 is disposed above the valve plate 443, and the second magnet 445 is fixedly coupled to the upper end of the valve plate 443. Specifically, the upper end of the valve plate 443 is provided with a connection housing 446, and the connection housing 446 and the valve plate 443 may be integrally formed. The connection housing 446 is provided with a receiving groove in which the second magnet 445 may be fixed by glue, screws, or the like.

The ends of the first magnet 444 and the second magnet 445 that are close to each other are magnetic poles of the same magnetism.

When the valve plate 443 swings upward to a horizontal state, the opening of the accommodating groove is opposite to the opening of the accommodating groove, at this time, the second magnet 445 is located directly above the first magnet 444, 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 an S-pole, the upper end of the first magnet 444 is an S-pole.

It can be appreciated that a certain magnetic repulsive force is generated between the first magnet 444 and the second magnet 445, so that the valve plate 443 can swing downward rapidly and automatically under the dual action of magnetic force and gravity, and the valve plate 443 can be tightly attached to the casing 441, so that the outlet of the drainage through hole 442 is completely closed, backflow is prevented, and the sanitation of the indoor space is ensured. The first magnet 444 and the second magnet 445 are permanent magnets.

Further, the housing 441 may be provided with a rubber ring at an outlet of the drain through hole 442. Specifically, the casing 441 is provided with an annular groove, the rubber ring is embedded into the annular groove, the rubber ring surrounds the outlet of the drainage through hole 442, when the valve plate 443 is abutted with the casing 441 and shields the outlet of the drainage through hole 442, the valve plate 443 is abutted with the rubber ring, so that the rubber ring is deformed and effectively fills the tiny gap between the valve plate 443 and the casing 441, thereby enhancing the sealing effect and avoiding odor from being emitted to the floor drain 400 from the tiny gap.

It will be appreciated that the collector 100, the trap 200, the floor drain 400 and the associated piping may be made of plastic. The first, second and third water level probes 110, 430 and 210 are made of a corrosion-resistant conductive material.

While the preferred embodiments of the present invention have been illustrated and described, the present invention is not limited to the embodiments, and various equivalent modifications and substitutions can be made by one skilled in the art without departing from the spirit of the present invention, and these are intended to be included in the scope of the present invention as defined in the appended claims.
