Description

TECHNICAL FIELD

[0001] The utility model relates to intelligent closestool technical field, concretely relates to a kind of intelligent closestool based on single infrared sensor. BACKGROUND

[0002] The automatic cover function of intelligent closestool usually uses two or more sensors to control the automatic cover of closestool seat ring and closestool cover and the automatic flushing of closestool. Although this design improves the convenience and hygiene of use, it also increases the manufacturing cost of closestool. The signals of multiple sensors work alternately, which not only increases the technical complexity, but also may cause malfunction or user experience decline due to signal interference or asynchronization between sensors. For example, if the sensitivity of the sensor is not properly set, it may cause the closestool cover to accidentally open when it is not needed, or not to open when it is needed, which is inconvenient for users. In addition, the increase of sensors also means an increase in user cost. Therefore, intelligent closestool manufacturers need to find a balance between improving product intelligence and controlling cost to ensure the cost performance and market competitiveness of the product.
