Description

This invention relates to an electronic nose, and more particularly to an electronic nose equipped with a gas exchange system and suitable for mounting on a robot. Robots are widely used in modern society in various application fields, including factory automation, home care, environmental exploration, disaster relief, security patrols, and gas detection. Robots are typically equipped with various sensing devices to detect their surroundings and take appropriate action. These sensing devices include electronic noses that can distinguish and quantify simple and complex odors, and gas sensors that detect, compare, and analyze gases in the environment, enabling numerous functions such as detection and warning of harmful gases, monitoring air quality, monitoring dangerous situations like fires or gas leaks, applications in disease and public health, and food analysis.

In this specification, please understand that the terminology used in the descriptions of various embodiments is for the purpose of describing specific examples, not to impose limitations. Unless otherwise explicitly indicated in the context or specifically limited to a number of elements, the singular forms “one” and “the relevant” used herein also include the plural forms. Furthermore, please understand that, as used herein, the terms “include” and/or “contain” mean that the described features, elements, and/or components exist and do not exclude the addition or existence of one or more other features, elements, components, and/or groups thereof. The indefinite and definite articles include both singular and plural forms unless it is clearly indicated in the context that one refers to the other. This invention discloses an electronic nose equipped with a gas exchange system, which, in one example, is suitable for mounting on a robot, which may be an autonomous mobile robot, an automated guided vehicle, an articulated robot, a humanoid robot, a collaborative robot, or a hybrid robot, or a mechanical robot or a bionic robot. Non-limiting specific examples include, for example, security robots, exploration robots, and home care robots. While these examples are given, the invention is not limited to these, and the robots used herein should be interpreted broadly. Figure 1 shows a robot 10 according to one embodiment of the present invention. The robot 10 is a wheeled robot equipped with an electronic nose 20. The robot 10 comprises a robot body 11, and the electronic nose 20 is mounted on the robot body 11. The electronic nose 20 performs real-time gas detection by exposing at least a portion of it from the housing of the robot 10 and contacting the external gas. The electronic nose 20 allows the robot 10 to continuously monitor changes in the gas in the surrounding environment and take necessary actions based on the detection results. The external gas refers to the environmental gas in the space where the robot 10 or the electronic nose 20 is located. For example, in factory or home environments, harmful gases such as carbon monoxide, carbon dioxide, ozone, sulfur dioxide, nitrogen dioxide, volatile organic compounds, and formaldehyde may be present in excess. The robot 10, using its electronic nose 20, can replace manual work by detecting the presence of these harmful gases, determining whether their concentrations exceed safety standards, and then generating corresponding warnings or activating ventilation systems to improve gas flow to the outside. Alternatively, in unknown or extreme environments such as the deep sea, caves, or outer space, a mobile robot 10 can be employed to analyze the gases in the environment in real time using its electronic nose 20, thereby providing information on the gas composition of that environment. Referring to Figure 2A, according to one example of the present invention, the electronic nose 20 includes an air supply unit 21, a detection unit 22, an air extraction unit 23, and a processing unit 24. The air intake port of the air supply unit 21 communicates with the outside, and in one example, the air intake port is provided in the housing of the robot 10 so as to come into contact with the external gas and enter the electronic nose 20. The detection unit 22 includes a chamber 220 and a detection module, the detection module may, but is not limited to, be located inside the chamber 220, and may be located in another posit
