Description

Technical Field

[0001] This utility model relates to the field of urinal technology, and in particular to an automatic flushing sensor-operated urinal. Background Technology

[0002] With the continuous improvement of public health standards and the popularization of water conservation concepts, automatic flushing sensor urinals, with their contactless operation and intelligent water-saving functions, are gradually becoming the mainstream configuration in public restrooms. However, traditional manual flushing urinals still have many problems that urgently need to be solved: users need to manually press the flush button, which not only increases the risk of cross-infection of bacteria, but also easily leads to malfunctions such as button damage and leakage; at the same time, manual flushing lacks precise water volume control, which easily leads to water waste and does not conform to the current development trend of energy conservation and emission reduction.

[0003] A sensor-operated automatic flushing urinal disclosed in publication number CN204081014U includes a flushing channel for flushing water, a flushing activation component placed on the flushing channel to control the flow of flushing water, a sensor component for detecting human body signals, a controller, a power supply component, and an opening for housing the sensor component and the power supply component, located on an inclined surface below the urinal's receiving interface. In this invention, the opening for housing the sensor component and the power supply component is placed in a relatively concealed position within the urinal, making the urinal more aesthetically pleasing. Furthermore, the sensor component and the power supply component can be directly removed from the opening for maintenance, offering advantages such as convenient assembly and disassembly, and low maintenance costs.

[0004] While the aforementioned patent achieves the goal of placing the sensor and power components in a relatively hidden position within the urinal, making the urinal aesthetically pleasing, and allowing the sensor and power components to be directly removed from the opening for maintenance, thus offering convenient assembly and disassembly and low maintenance costs, the device lacks a function for quantitative control of flushing volume, failing to meet the diverse needs of different locations for water-saving efficiency and cleaning effectiveness.

[0015] (III) Beneficial Effects

[0016] This utility model provides an automatic flushing sensor-operated urinal, which has the following beneficial effects:

[0017] 1. This automatic flushing sensor-operated urinal, through the setting of a quantitative control mechanism, has a flow meter installed near the water inlet during use. The flow meter can detect the water flow at the inlet in real time. If the flow exceeds the preset value, the flow meter transmits a signal to the PLC controller on one side, and the PLC controller then controls the opening and closing of the electric control valve, thereby achieving the effect of quantitative control of the flushing volume. This can meet the differentiated needs of different places for water-saving efficiency and cleaning effect, and avoid excessive water use and waste of water resources.

[0018] 2. This automatic flushing sensor-operated urinal, through the setting of the adjustment mechanism, first uses a photoresistor to detect the intensity of external light during use. If the intensity is too high, the power is turned on, and the electric push rod drives the telescopic baffle below the end fixing block to slide inside the fixing plate, thereby adjusting the position of the telescopic baffle. This achieves the effect of blocking external sunlight, preventing the infrared sensor below from being affected by external sunlight and causing false judgments or false triggers.
