Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a sample detection filter for food detection. Background Art

[0002] Food safety is a hot topic in research in the world today. Food directly affects people's health and even life. Food needs to pass experimental testing by relevant departments before use to ensure its safety when consumed.

[0003] For example, a sample detection filter for food testing with publication number CN220802254U drives a brush set on the filter screen to move back and forth on the filter screen through a series of transmission structures, thereby achieving the purpose of cleaning the filter screen and preventing the filter screen from being blocked. The turntable is driven to rotate by a motor, and the slope block on the turntable cooperates with the pulley column to push the upper structure to perform reciprocating vertical displacement, thereby achieving the purpose of filtering in vibration and improving the filtering efficiency. However, when the brush moves back and forth on the filter screen, the samples blocked by the filter screen will be pushed to both sides and not cleaned. After long-term use, they will accumulate on the filter screen, and then become moldy and rotten, affecting subsequent use. The rotation of the turntable drives the upper structure to vibrate through the slope block, and most parts of the device are vibrating, which consumes a lot of energy and affects the stability of the device. For this reason, a sample detection filter for food testing is proposed for improvement. Utility Model Content
