Description

Technical Field

[0001] This utility model relates to the field of tea selection technology, specifically to a tea selection machine. Background Technology

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea plant. Other names include tea, jia, ming, and chuan. Tea contains catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid, all of which are beneficial to health. Tea beverages are one of the world's three major beverages.

[0003] Utility model patent CN217940885U discloses a tea selection device, belonging to the field of tea screening machines. It includes a screening machine support frame, with a tea sieve mounted on the upper end of the frame. A tea baffle is mounted on the tea sieve, and the baffle includes a connecting rod and a baffle body. The baffle body is mounted on the lower end of the connecting rod, and two angle adjustment structures are symmetrically installed on the connecting rod. These angle adjustment structures can slide inwards and outwards on the connecting rod. Each angle adjustment structure includes a mounting base, a fixing pin, a telescopic connecting pin, and an anti-detachment pressure plate. By setting the tea baffle, it can block piled-up tea leaves, thus flattening and separating them, allowing for effective selection and grading of the tea. The angle adjustment structures and the push spring allow for easy adjustment of the distance between the tea baffle and the bottom of the tea sieve, thereby adjusting the thickness of the piled-up tea leaves spread on the tea sieve.

[0004] However, the aforementioned devices still have some drawbacks in practical use. The most obvious is the lack of a dust removal structure. During the pouring process of unselected tea leaves, a large amount of dust is generated. If this dust is not cleaned up promptly, it will quickly spread into the surrounding environment, causing significant harm to the personnel selecting the tea leaves over time. Furthermore, the dust will eventually settle on the selected tea leaves, reducing their quality. Therefore, to solve these problems, we propose a tea selection machine. Utility Model Content
