Smart urinal with multi sensing electric fields

Abstract

A smart urinal with multi sensing fields comprises a urinal body, two or more proximity capacitive sensing electric field means and a flushing control unit. A urinal body, a urinal facade which forms a basin, and a cavity arranged inside the urinal body. The two or more proximity capacitive sensing electric field means, which are arranged in the cavity; an proximity capacitive sensing electric field is formed around the proximity capacitive sensing electric field means; said proximity capacitive sensing electric field means individually generate proximity capacitive Sensing information according to a change of the electric field energy caused by the proximity capacitive sensing electric field corresponding to a sensed object. The flushing control unit, which receives the proximity capacitive sensing information, and controls the bowl area flushing according to one or more logic operation results in the received proximity capacitive sensing information,

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to a urinal, and more particularly to a smart urinal with mufti sensing electric fields.[0003]2. Description of Related Art[0004]In order to improve environmental sanitation and life quality, people continuously improve urinals, comprising wall-mounted urinal, manual-operated urinal and modern smart urinal. Besides flushing function, the smart urinal can provide various convenient and friendly functions for users. Especially, the urinal has automatic flushing without any touch, and can reduce chance of contacting diseases.[0005]In order to make the invented urinal, achieve the above functions, infrared ray sensors should be equipped to sense action of humans. In sensing by the infrared ray sensors, any obstacle is not allowed between the transmitting terminal and the sensing terminal, and thus, the transmitting terminal must be installed on the exposed urinal. The common installat...

Benefits of technology

The patent text describes an improvement to a urinal that uses proximity capacitive sensing to detect when a person's hands are near the urinal. This improvement allows the sensing electric field to be positioned in a way that it doesn't need to be exposed in a wet environment, which increases the lifespan of the sensing means and reduces installation space. The sensing accuracy is not affected by objects blocking the sensing area. Additionally, by using multiple sensing means, the urinal can make more complex decisions and automatically flush the urinal based on the amount of water needed, improving sanitation and convenience.

Problems solved by technology

Due to exposure to damp environment of the toilet, it may be affected with damp.

In addition, it occupies space and affects ventilation.
