Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a device for detecting alcohol content. Background Art

[0002] Liquor is a liquid made from grains through fermentation. Its main chemical component is ethanol, which generally contains trace amounts of fusel alcohols. It is a drink with national cultural characteristics. When producing liquor, it is necessary to test the alcohol content of the liquor. During the testing process, the liquor sample is usually placed in a test bottle, and the alcohol concentration and temperature of the liquor are tested using an alcohol tester and a thermometer. Data is collected and the results are calculated according to the formula.

[0003] For example, a Chinese patent with publication number CN219496343U discloses a liquor alcohol concentration detection device based on food detection, including a box, an alcohol detector and two temperature sensors. Two supporting feet are provided on the left and right sides of the bottom of the box, and a feed pipe with one end extending to the inside is provided on the left and right sides of the box. The liquor alcohol concentration detection device based on food detection starts the first servo motor to drive the alcohol detector and the temperature sensor to move downward, so as to detect liquor of different depths. Secondly, the alcohol detector and the temperature sensor are driven to move left and right by starting the second servo motor. Furthermore, the alcohol detector and the temperature sensor can be driven to move forward and backward by starting the third servo motor to further expand the detection range, and finally achieve the purpose of a wide detection range, so as to improve the accuracy of the detection results.

[0004] The technical solution recorded in this scheme is to rotate the threaded sleeve to move the first threaded rod inside it and the alcohol detector and temperature sensor at the bottom of the threaded rod downward, and rotate the second threaded rod to realize the left and right movement of the alcohol detector and the temperature sensor, and rotate the third threaded rod to set the alcohol detector and the temperature sensor to move forward and backward to expand the detection range. However, in actual use, the sample wine directly enters the interior of the box through the feed pipe. When the test is completed, the sample wine is discharged from the discharge pipe, but at this time, wine will remain on the inner wall of the box, and the inner wall of the box needs to be cleaned. After cleaning, water droplets will remain on the inner wall. When the next sample wine to be tested is poured in again, the wine will be mixed with the water droplets remaining on the inner wall of the box, thereby affecting the wine content detection.
