Solution Overview

Problem

Conventional detecting devices for substances in containers require large spaces for installation due to the need for opposite placement of transmitting and receiving modules, leading to potential false detections from weak signal strength, and are costly and energy-intensive when using laser technology.

Innovation Solution

A detecting device with a light-emitting element and a light-receiving element positioned at non-parallel points on the container, allowing for a compact installation and eliminating the need for precise calibration, using a substrate body with intersecting planes to define a V-shaped indentation for the container, enabling direct attachment and reduced assembly time.

AI summary

A detecting apparatus includes a container, and a detecting device including a transmitting module and a receiving module. The transmitting module includes a light-emitting element provided at a first point of the container and operable to transmit a photo signal to propagate toward the container along an optical path. The receiving module includes a light-receiving element provided at a second point of the container and configured to receive the photo signal transmitted through the container. The receiving module is operable to determine whether a substance is present within the container based on receipt of the photo signal. An imaginary tangent plane tangent to the first point is not parallel to an imaginary tangent plane tangent to the second point.
