Sewage overflow warning device

The invention relates to an inductive automatic flushing container (for example: a urinal, a washbasin), in particular to a sewage overflow warning device.

Generally, there are inductive automatic flushing containers (for example, urinals and washbasins). For example, the urinal flushing operation mode is nothing more than manual and automatic sensing. Referring to FIG. 1 , a schematic diagram of a urinal showing an inductive automatic flushing is mainly composed of a urinal body 11 , a solenoid valve 12 , and an infrared sensor 13 for performing small flushing. The rinsing body 11 is connected to the water source 15 through the pipe body 14 and has a sump 111 and a bottom surface of the sump groove 111 and the outside. The electromagnetic discharge valve 112 is a pipe body 14 disposed between the water source 15 and the urinal body 11 to close or open the water source 15. In a normal state, the electromagnetic valve 12 closes the water source 15, and The infrared sensor 13 is electrically connected to the electromagnetic valve 12 to control the actuation of the electromagnetic valve 12. When the infrared sensor 13 senses an object, the electromagnetic valve 12 is controlled to be turned on to perform a flushing operation. However, the conventional inductive automatic flushing urinal still has the following defects requiring immediate improvement in actual use cases.

When the liquid discharge hole 112 of the urinal body 11 is plugged by a foreign object, once the uninformed user comes forward, although the blockage is found and then leaves, the infrared sensor 13 still senses the object (user) ) the solenoid valve 12 is opened The action of the flushing causes the sump 111 of the urinal body 11 to accumulate sewage and overflow.

Accordingly, how to develop a sewage overflow warning device that can solve the above-mentioned drawbacks, that is, the motivation of the present invention.

The object of the present invention is to provide a sewage overflow warning device, which mainly stops the sensing function when the liquid discharge hole of the container (for example, a urinal or a washbasin) is blocked, and cannot perform the flushing action to avoid the sewage. Accumulate and overflow the container (for example: urinal, washbasin).

In order to achieve the foregoing objective, a sewage overflow warning device according to the present invention includes: a liquid level sensor disposed in a liquid collection tank of the container body, when the liquid storage tank accumulates water, The liquid level sensor outputs a liquid level sensing signal; when the liquid storage tank is drained, the liquid level sensor stops outputting the liquid level sensing signal; and a control unit electrically connects the liquid surface feeling Between the detector and the infrared sensor of the container, and having a control circuit and a relay, the control circuit is electrically connected to the liquid level sensor, and when the control circuit receives the liquid level sensing signal, the output is controlled. a signal, the relay is electrically connected between the control circuit and the infrared sensor, and when the relay receives the control signal, the infrared sensor is controlled to stop; when the liquid level sensor stops outputting the control signal, The infrared sensor resumes operation.

Preferably, the control circuit further outputs a warning signal after receiving the liquid level sensing signal, and the sewage overflow prevention device further comprises an electrical connection to the control circuit. The warning device performs an alerting action when the alerter receives the warning signal, and stops when the liquid level sensor stops outputting the control signal.

Preferably, the alerter is a warning light or a buzzer.

Preferably, the container is a urinal.

The present invention has been described in connection with the preferred embodiments of the present invention in accordance with the accompanying drawings.

Referring to Figures 2 and 3, a sewage overflow warning device according to an embodiment of the present invention is applicable to a container for inductive automatic flushing (for example, a urinal, a washbasin), and the embodiment is a urinal For example, the urinal is mainly composed of a urinal body 21, a solenoid valve 22, and an infrared sensor 23, since the urinal body 21, the electromagnetic valve 22, and the infrared sensor 23 are known. The components, and the manner of operation thereof are the same as those of the prior art, and are not the focus of the invention. Therefore, the detailed structure and operation mode of the components are not described in detail; and the sewage overflow prevention device is mainly composed of a liquid level sensing. The device 30, a control unit 40, and a warning device 50, wherein:

The liquid level sensor 30 is disposed in the liquid collection tank 211 of the urinal body 21, and when the liquid collection tank 211 accumulates water, the liquid level sensor 30 outputs a liquid level sensing signal; The liquid level sensor 30 is in the form of a sensing rod, and the position of the liquid level in the liquid collecting tank 211 can be determined according to the liquid level required to be alerted.

The control unit 40 is electrically connected between the liquid level sensor 30 and the infrared sensor 23 of the urinal, and has a control circuit 41 and a relay 42. The control circuit 41 is electrically connected to the liquid level sensor 30. When the control circuit 41 receives the liquid level sensing signal, it outputs a control signal and a warning signal. The relay 42 is electrically connected to the control circuit 41 and Between the infrared sensors 23, when the relay 42 receives the control signal, the infrared sensor 23 is controlled to stop. In this embodiment, the power contact of the infrared sensor 23 can be electrically connected. At the normally closed contact of the relay 42, in a normal state, the normally closed contact of the relay 42 remains in a conductive state, and the infrared sensor 23 is activated, and when the relay 42 receives the control signal, an excitation is generated. When the connection state of the normally closed contact is changed, the power is turned off. At this time, the power of the infrared sensor 23 is turned off, and the infrared sensor 23 stops the sensing operation.

The warning device 50 is a warning light that emits strong light, and may also be a buzzer that emits a sound. The warning device 50 is electrically connected to the control circuit 41. When the warning device 50 receives the warning signal, the warning device 50 performs an alerting action. When the water accumulated in the liquid collection tank 211 subsides, the liquid level sensor 30 outputs a signal to stop the excitation of the relay 42 and restore the connection state of the normally closed contact. At this time, the power of the infrared sensor 23 is restored, and the power is restored. The infrared sensor 23 restores the original sensing action and also stops the actuation of the alerter 50.

The above description is the structure and configuration description of each main component of the embodiment of the present invention. The mode of operation of the present invention and its efficacy are explained below.

Referring to Figures 2 to 4, when the user uses the urinal, the infrared sensor 23 senses the user (object), and then controls the solenoid valve 22 to open the water source 24 for the first flush. After the user leaves, the second time At this time, the liquid level sensor 30 detects whether the liquid discharge hole 212 of the urinal body 21 is blocked and causes the liquid collection tank 211 to accumulate sewage. When the sump 211 does not accumulate sewage, the liquid level sensor 30 does not output a liquid level sensing signal, and the urinal can be used normally. When the sump 211 accumulates the sewage, the liquid level sensor 30 senses the sewage water level and outputs a liquid level sensing signal to the control circuit 41 of the control unit 40, and the control circuit 41 outputs a warning. The signal is sent to the warning device 50, and the warning device 50 is activated to notify others to perform the clogging elimination operation. At the same time, the control circuit 41 outputs a control signal to the relay 42 to generate excitation and cut the infrared ray sensor 23. The power supply makes the urinal unable to perform the flushing action, so as to avoid the accumulation of sewage and out of the urinal, and save water.

Immediately, when the clogging condition has not been eliminated, the relay 42 remains in the excited state, and the power of the infrared ray sensor 23 is continuously turned off, and the state of flushing cannot be performed, and when the clogging condition is excluded, the set The sewage in the liquid tank 211 is discharged outside. At this time, the liquid level sensor 30 senses the liquid level of the sewage and stops outputting the liquid level sensing signal to the control unit 40. The relay of the control unit 40 42, the excitation is stopped, and the infrared sensor 23 is restored to a state in which sensing can be performed, so that the urinal can be used again.

Accordingly, according to the present invention, when the drain hole 212 of the urinal is blocked, the sensing function is stopped, and the flushing operation cannot be performed to prevent the sewage from accumulating and overflowing the urinal.

The invention can at least achieve the following effects:

First, when the sump 211 of the urinal body 21 accumulates sewage, the control unit 40 outputs a warning signal to the warning device 50, so that the warning device 50 simultaneously informs others by sound or light or sound and light. The clogging elimination action, therefore, the clogging is eliminated early, and the sanitary equipment is effectively monitored and monitored. In addition, when a plurality of urinals are provided with the sewage overflow prevention device of the present invention, the warning output by the control unit 40 can be further The signal is transmitted to the monitoring room. Once the urinal is blocked, the monitor can immediately identify the blocked urinal, and immediately eliminate the clogging state, so that the sanitary equipment can be monitored and managed more effectively.

Secondly, since the sewage overflow prevention device of the present invention is mainly composed of a liquid level sensor 30, a control unit 40, and a warning device 50, and the sewage overflow prevention device can be compatible with the old system. The utility model is provided on the old inductive automatic flushing urinal, and the original design is not required to be changed.
