Description

Technical Field

[0001] The utility model relates to the technical field of bathrooms, in particular to an intelligent toilet laser foot sensor. Background Art

[0002] The smart toilet laser foot sensor is a device that uses a laser sensor to achieve automatic sensing. When the user approaches the toilet and triggers the sensor, the laser sensor will send out a laser beam and detect the signal reflected back. By analyzing these signals, the sensor can determine the user's actions, such as approaching, leaving, or kicking. According to the user's actions, the sensor can automatically control the toilet lid opening and closing, flushing and other functions, thereby providing a more convenient and hygienic user experience.

[0003] At present, the circuit board in the existing laser foot sensor is installed in the shell, and is usually sealed with a sealing ring. The effect of sealing depends largely on the quality and installation accuracy of the sealing ring. If the quality of the sealing ring is poor or it is improperly installed, assembly gaps may appear, causing the circuit board to be damaged by external factors such as moisture and dust. With a single sealing method, once there is a problem with the sealing ring, the entire sealing system will fail and cannot provide effective protection, which not only affects the sealing effect but may also shorten the service life of the sensor.
