[0027] In this embodiment, the weighing sensor 603 adopts a spoke-type weighing sensor, but it is not limited to this. Other types of sensors can also be used as long as they can achieve the weighing of the carbon dioxide cylinder.

[0028] The diameter of the sensor placement groove 6011 is smaller than the diameter of the base plate 601. The upper end of the weighing sensor 603 extends radially outward to form a limiting boss. The weighing sensor 603 is placed in the sensor placement groove 601. The lower surface of the limiting boss rests on the base plate 601 and is connected to the base plate 601.
