Description

Urinal automatic flushing system

This creation is about a urinal automatic flushing system, especially a system that detects the presence of urine flow on the surface of the urinal. It can identify the current frequency in the urinal through the resonant frequency generated by the surface of the urinal. The state of no liquid flow, clean liquid flow or urine flow, so that the system determines whether it is necessary to provide a cleaning liquid, such as clean water to clean the urinal.

Press, the urinal is a kind of urinal facility installed on the wall, which has a urinal space for the user to be small and convenient. Compared with the toilet, the urinal occupies less space and consumes less water, so Toilets located in public places usually see the setting of the urinal; in general, the flushing mode of the urinal is divided into manual and automatic, and the manual system is provided with a push-type or knob-type flush valve, which is connected. To the water inlet hole of the urinal, when the user ends the urination, press the flush valve, the water can flow into the water inlet hole to clean the urine attached to the surface of the toilet bowl, and take the urine out of the water outlet hole; The user needs to manually open and close the flush valve. When multiple people are in contact, the health problem is often criticized. If the user does not flush after use, it is easy to produce an unpleasant smell of urine. If it is closed, it will cause waste of water flow, so the manual flush valve is no longer used in public places.

The automatic flushing technology of the urinal mainly detects whether there is a human body in front of the urinal. More practice is to connect an infrared sensor above the toilet bowl space. When the user is in the toilet, the infrared sensor is used. The emitted infrared rays will be blocked and reflected by the human body. At this time, when the infrared sensor receives the reflected infrared rays, it can be judged that some people are currently using the urinal, so that the flush valve starts the first flush. Water, after the user leaves, the infrared rays emitted by the infrared sensor are no longer blocked, and then the flush valve starts the second flushing. This method does not require the user to control the flushing. The valve, therefore, will not have the problem of forgetting to flush, so that the urinal can also be kept clean.

The Republic of China New Patent Bulletin No. TW M517763 "Smart urinal device" is provided with an infrared sensor in front of the upper edge of the urinal body. The red line sensor is used to sense whether a user is close to the urinal and is detected. When there is a user, the control unit controls the valve to open, and starts cleaning the urinal with clear water. Moreover, the Republic of China invention patent number TW I547622 "Multi-induction field smart urinal" is used to set up multiple proximity induction electric field components in the urinal. In order to establish a proximity sensing electric field region, when an object enters the region, proximity sensing information can be generated, thereby detecting whether a human body is approaching, and the proximity sensing electric field component must be separately set at different positions to increase the sense. The accuracy of the measurement.

However, such a method for sensing the approach of the human body has a great chance of causing a false positive judgment of the sensing device. In the case of an infrared sensor, it may be misjudged due to the light of the light or even the color of the user's clothes. The water that flushes the urinal is continuously flowing out or cannot flow out; and if the sensing distance of the sensor is not grasped, the object that is too far will be sensed, for example, the person passing through may be sensed, and there may be a feeling Some non-human objects are detected, so that the water washes the urinal continuously, resulting in waste of water resources; if the number of sensors is increased, multiple sensors are compared to determine whether a user is actually using a urinal, but Such a design requires a large accommodating space in the urinal or surrounding to accommodate a plurality of sensors, which results in a complicated system structure.

Therefore, how to improve the above-mentioned device for sensing the proximity of the human body, reduce the probability of misjudgment, and accurately judge that the urinal is being used, and clean the urinal in a timely manner, which becomes the direction that the creator thinks.

Nowadays, the creator is still in the spirit of tirelessness in view of the above-mentioned existing urinal automatic flushing sensing device, which is a tireless spirit, and with its rich professional knowledge and years of practical experience.

The resonant frequency recognizes that the current flowing in the bowl is a clean liquid or urine, and it can also recognize that the current urinal is in a state of no use when there is no liquid flow.

In order to achieve the above-mentioned implementation, an automatic urinal flushing system is provided, which comprises a urinal body having a urinal surface and a back surface of a urinal surface, the urinal back having an accommodating space; at least one The resonant sensor is disposed in the accommodating space to detect the flowing liquid on the urinal surface; a power supply module is disposed in the accommodating space; a buzzer is disposed in the accommodating space; and a micro control The device is electrically connected to at least one resonant sensor, the power supply module, and a valve controller.
