Description

Technical Field

[0001] This utility model relates to the field of air quality detection equipment technology, and more specifically to the field of a system for detecting compressed air quality. Background Technology

[0002] In various stages of the liquor production process, multiple processes require stirring the liquor, and compressed air, as the power source for stirring, comes into close contact with the liquor. Existing patents disclose the following technologies: Patent publication number CN118112083A, entitled "Air Quality Detection Method and Air Quality Detection Device," discloses the following: An air quality detection method and air quality detection device in the field of vehicles. The detection device proposed in this application includes an AC excitation source, a first electrode, a second electrode, and a detection module. The AC excitation source outputs a first AC signal to the first electrode. Upon receiving the first AC signal, the first electrode transmits the first AC signal through the air to the second electrode. The second electrode receives a second AC signal from the first AC signal transmitted through the air and transmits it to the detection module. The detection module can detect the air quality between the first and second electrodes based on the first and second AC signals. The technical solution of this application can also control the vehicle's ventilation system based on the air quality detected by the detection module, thereby improving the air quality inside the vehicle and thus enhancing the user's riding experience.

[0003] Patent publication number CN102721789A, entitled "Air Quality Detection Ball," discloses the following: An air quality detection ball. The detection ball comprises a hollow glass sphere with a hollow conduit at its bottom. One end of the conduit is located inside the hollow glass sphere, and the other end is connected to the outlet of a miniature air pump. The inlet of the miniature air pump is connected to a smoke-generating device, which is connected to a control circuit. The control circuit is connected to a carbon dioxide sensor. When in use, if the carbon dioxide content is too high, the control circuit controls the smoke-generating device to emit smoke. The transparency and turbidity within the hollow glass sphere provide a visually intuitive representation of the current carbon dioxide content in the air. This transparency and turbidity facilitates understanding and helps convey information about whether the carbon dioxide content is too high, thus reminding and assisting users in maintaining a healthy and comfortable living environment.

[0004] The aforementioned patents are not applicable to the evaluation of baijiu (Chinese liquor). Currently, the commonly used detection method involves releasing compressed gas into the air and relying on human senses to determine the presence of any off-odors. However, this method suffers from instability in the evaluation criteria, strong subjectivity among the evaluators, and limited evaluation dimensions, necessitating improvements in the comprehensiveness, reliability, and accuracy of the evaluation.
