[0002] As people pursue the concept of healthy life, the popularity of sparkling water as a healthy drink is increasing. As a device that can produce carbonated beverages at home, the emergence of sparkling water machines allows consumers to easily make their favorite sparkling water. The principle of the sparkling water machine is to press the carbon dioxide in the gas supply body into the bottle filled with water, so that the water in the bottle becomes sparkling water. At present, many sparkling water machines on the market are connected to the water bottle and the gas injection nozzle by tightening the thread, which is troublesome and time-consuming to operate. In addition, once the assembly angle is incorrect or over-tightened, it is easy for the thread to not align correctly, the thread to slip, and it cannot be quickly connected, which reduces the user experience.

[0004] A limiting mechanism comprises: a mounting seat, the mounting seat being provided with a cavity and an opening communicating with the cavity; a limiting assembly, the limiting assembly comprising at least two limiting units, the limiting unit comprising an operating part and an abutting part, one end of the operating part passing through a side wall of the mounting seat, extending into the cavity and being arranged opposite to the opening, the other end of the operating part being connected to the abutting part extending downward, the abutting part being elastic, the limiting unit having at least a locked state and an unlocked state, and when the limiting unit is in the locked state, the abutting parts of at least two of the limiting units are configured to cooperate to clamp the outer peripheral wall of a water bottle, and the operating part is configured to be pressable so that the limiting unit switches to the unlocked state, so that the abutting part flips outward to release the outer peripheral wall of the water bottle.

[0005] The present application provides a limiting mechanism, wherein a limiting assembly including at least two limiting units is provided on a mounting seat, and the abutment portion of each limiting unit is configured to cooperate to clamp or release the outer peripheral wall of a water bottle. Since the abutment portion can undergo elastic deformation, when a user installs the water bottle and inserts the top of the water bottle between the abutment portions, the water bottle will abut against the abutment portions and drive the abutment portions to be broken apart, and ensure that the abutment portions always clamp the outer peripheral wall of the water bottle. In addition, the limiting unit is also provided with an operating portion for pressing, and the user can drive the operating portion to drive the abutment portion to flip outward by pressing the operating portion through the opening, thereby releasing the locking of the water bottle by the limiting unit, and the user can quickly and easily take out the water bottle, which is simple and convenient to operate.

[0006] In one embodiment, the side wall of the mounting seat is provided with an axial hole arranged in the horizontal direction, the number of the axial holes is consistent with the number of the limiting units, the end of the operating portion away from the cavity is formed with a rotating shaft, the rotating shaft is connected to the abutting portion, the rotating shafts of at least two limiting units are rotatably inserted in the axial hole in a one-to-one correspondence, and the operating portion is configured to be able to rotate around the rotating shaft when pressed downward, so as to drive the abutting portion to rotate outward around the rotating shaft and release the outer peripheral wall of the water bottle. By adopting the above structure, when the user needs to take out the water bottle, the limiting unit can be rotated around the rotating shaft by pressing the operating portion, so that the abutting portion flips outward around the rotating shaft and separates from the outer peripheral wall of the water bottle, thereby realizing automatic unlocking, and the operation is simple.

[0007] In one embodiment, the mounting seat includes a cover body and a base, the cover body is detachably arranged on the base, the cover body is provided with the opening, the cover body and the base are enclosed to form the cavity, the bottom of the cover body and the top of the base are matched to form the shaft hole, and the two sides of the rotating shaft are respectively against the cover body and the base. By providing a detachably connected cover body and base, the limit assembly is first positioned and installed on the base through the shaft hole, and then connected to the base through the cover body so that the rotating shaft of the operating part is stably clamped between the cover body and the base, thereby making the limit assembly easy to install.

[0008] In one embodiment, the cover is provided with a first connection hole, the base is provided with a second connection hole, and the first connection hole and the second connection hole are connected to the cover and the base by a fastener.
