[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] A tea drinking machine according to the prior art is characterized in that it is equipped with a plurality of conveniently replaceable material bags. These material bags are detachably mounted on the tea drinking machine through a special bag hanging rack, and the material bags are used to store liquid materials. One of the material bags is designed with a hanging part, which is not only a fixing point for the material bag, but also used as a filling port for the material bag. After the filling operation is completed, this part will be sealed to ensure the freshness and safety of the material. A valve is also provided on the material bag, which is usually a ball valve structure with a built-in elastomer. When the valve is lifted upward, the valve will open and the liquid will flow out of the material bag. When the valve moves downward under the action of the elastic member, the valve will close and the liquid cannot flow out of the material bag.

[0004] In the invention patent application with application number CN 2024105867191, a turntable structure for a beverage machine is provided, wherein the turntable assembly includes an upper turntable and a lower turntable, wherein the upper turntable is provided with a plurality of slots, and the upper end of the bag hanging rack can be inserted into the slot from the side of the upper turntable. However, in this application, the slot on the upper turntable is deep, and when removing the bag hanging rack, the operator needs to lift the bag hanging rack with one hand and move a distance along the slot, which is not only inconvenient to operate, but also the upper end of the bag hanging rack is prone to collide with the side of the slot. In addition, in the process of installing the bag hanging rack on the turntable, the operator must align the locker at the lower end of the bag hanging rack with the locking sleeve, and then move downward. At this time, a material bag filled with materials is hung on the bag hanging rack, and the operator's one-handed operation process is relatively laborious, and the locking sleeve is located inside the beverage machine and is difficult to observe. Therefore, in this process, multiple alignments are often required to correctly install the bag hanging rack on the turntable, which greatly reduces the speed of changing materials. In addition, when the hanging material bag is rotating or operating, its lower corners may collide with other objects or equipment, causing safety hazards. It may also cause operators to need additional steps when installing or removing, reducing work efficiency. In response to this, the technicians have made further improvements to the structure of the bag hanging rack to address the problems that arise during use.
