Distance warning device for urinal and its warning method

The invention relates to a warning device, in particular to a urinal distance warning device capable of issuing a warning signal to remind a user to approach a urinal when urinating, to completely put urine into the urinal and a warning method thereof.

In the average family, the toilet is used to provide people with instant excretion. In the toilet space where many people can use together in schools, companies, stores, etc., toilets and urinals are often designed at the same time to provide people with different needs.

However, due to the different public health habits of each person, some users often inadvertently urinate at a distance from the urinal, so that the urination is not fully invested in the urinal, causing the urine to drop around. In this way, not only will the floor of the bathroom be wet and pollute, but it will affect the sanitation and increase the workload of the cleaning staff.

In view of this, in order to improve the above-mentioned shortcomings, the urinal distance warning device can promptly prompt the user to approach the urinal to completely discharge the urine into the urinal, thereby maintaining environmental sanitation and reducing the burden on the cleaning personnel, inventing The experience of the people and the continuous research and development improvements have not produced the invention.

The main object of the present invention is to provide a distance warning device for a urinal and a warning method thereof, which provide a warning signal when the user approaches the urinal but cannot push the urine into the urinal. The method and method can prevent the urine from dripping around when the user urinates, in order to maintain environmental sanitation and reduce the manpower of the cleaning work.

A secondary object of the present invention is to provide a distance warning device for a urinal and a warning method thereof, which is issued immediately when a user approaches a urinal but cannot put urine into the urinal and stays at the position for a predetermined time. The structure and method of the warning signal can ensure the correctness of the human body detection to control the operation of the warning signal and the flusher.

Please refer to FIG. 1 and FIG. 2 , which is a first embodiment of the urinal distance warning device 1 of the present invention, comprising a casing 2, a detector 3, a comparison circuit 4 and a control circuit 5.

The outer casing 2 is a rectangular casing whose front end is roughly inclined, and the outer casing 2 may be another three-dimensional casing selected as needed. The inside of the outer casing 2 forms an accommodating space, and the rear end of the outer casing 2 is coupled to the wall surface. In practice, the outer casing 2 can also be directly embedded in the wall or embedded above the front end of the urinal.

The detector 3 is a photoelectric sensor, and the detector 3 is disposed at the front end of the casing 2 for detecting the position of the human body, and the detector 3 can also adopt the human body according to the environmental requirement (heat Interpretation) Sensors, ultrasonic sensors or microwave sensors also have the ability to detect the position of the human body.

The comparison circuit 4 includes a first comparator 41 and a second comparator 42. The first and second comparators (41, 42) are respectively electrically connected to the detector 3 for comparing and outputting the human body 9 and The urinal 91 is a signal located at a first distance H1 or a second distance H2 (as shown in Fig. 3). In implementation, when the signal strength of the detector 3 is insufficient, the detector 3 and the comparison circuit 4 are electrically connected in series.
