Liquid level detection mechanism for beverage filling

The utility model belongs to the technical field of beverage filling, and particularly discloses a liquid level detection mechanism for beverage filling, which comprises a beverage can, the top of the beverage can is movably connected with a can cover through a spinning mechanism, and the outer surface of the beverage can is fixedly connected with a fixing frame. An intelligent warning mechanism used for automatically prompting the liquid level in the beverage can is arranged on the outer surface of the fixing frame. According to the liquid level detection mechanism for beverage filling, in the process that beverage in a beverage can is gradually reduced due to filling, the liquid level in the beverage can gradually descends, in the process, the height of a floating ball can be reduced along with descending of the liquid level, and at the moment, when an adaptive connecting piece makes contact with liquid level sensors of different heights, the liquid level sensors are in contact with the floating ball; throu
