Problems solved by technology

This method requires a heating device, which is complicated to operate and has potential safety hazards
In addition, the traditional edible oil gas detection method, because the density of oil and gas is higher than that of air, will settle at the bottom before the oil and gas reach the detection device, resulting in low oil and gas content in the air, which will lead to detection failure and low detection sensitivity

Abstract

The invention discloses a novel electronic nose air inlet system. An air storage device comprises a closed container, an air inlet pipe and an air guide pipe, the closed container is provided with twobottle openings, the two bottle openings are each provided with a bottle plug with a hole, one bottle plug stretches into an air inlet pipe, the other bottle plug stretches into the air guide pipe, and the length of the part, stretching into the closed container, of the air inlet pipe is more than half. The air guide pipe only extends into the bottle plug not more than 2cm; an air blowing devicecomprises a three-way pipe, two air blowers and two air blowing outlet pipes; an air chamber comprises a chamber body, two N-way pipes and 2(N-1) gas sensors, one ends of the two N-way pipes are connected with two blast air outlet pipes respectively, the other N-1 ends of the two N-way pipes are each internally provided with one gas sensor, and the number of the gas sensors is 2(N-1). Different gas sensors are arranged to detect the variety of edible oil, the air storage device does not need to be heated, and safety and reliability are achieved.

Description

technical field [0001] The invention belongs to the technical field of food detection and relates to a novel electronic nose air intake system. Background technique [0002] The traditional way to obtain gas from liquid oil is to heat the liquid oil to promote the volatilization of edible oil. This method requires a heating device, the operation is complicated and there are potential safety hazards. In addition, in the traditional cooking oil gas detection method, since oil and gas are denser than air, before the oil and gas reach the detection device, they will settle at the bottom, resulting in low oil and gas content in the air, which will lead to detection failure and low detection sensitivity. Contents of the invention [0003] In order to solve the above-mentioned problems, the technical solution of the present invention is: a novel electronic nose air intake system, including an air storage device, an air blowing device and an air chamber connected in sequence, whe...
