[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] Reference Figures 1 to 4According to the first embodiment of the utility model, the juice extraction mechanism includes a cup body assembly 100, a juice extraction assembly 200, a limiting structure and an adjusting assembly 300. The cup body assembly 100 is provided with a juice extraction chamber 110. The juice extraction assembly 200 includes a connecting shaft 210 and a screw body 220 connected to one end of the connecting shaft 210. The screw body 220 is accommodated in the juice extraction chamber 110. The other end of the connecting shaft 210 is passed through the cup body assembly 100. The limiting structure is arranged between the other end of the connecting shaft 210 and the cup body assembly 100. The limiting structure is used to limit the axial movement of the connecting shaft 210. The adjusting component 300 can be movably arranged on the cup body component 100. The adjusting component 300 is used to connect or disconnect the limiting structure. In this way, by setting the limiting structure, the axial movement of the screw body 220 along the connecting shaft 210 can be limited to avoid the situation where the screw body 220 is lifted by the fruit during juicing, resulting in the screw body 220 being unable to squeeze juice. The traditional technical solution of using the cover body to abut the upper end of the screw body 220 can be abandoned to improve the taste of food.

[0037] Specifically, when juicing, the connecting shaft 210 drives the screw body 220 to rotate in the juicing chamber 110 under the action of the driving motor 700, so that the screw body 220 can drive the fruit to move downward, and the fruit abuts against the screw body 220 and the side wall of the juicing chamber 110 respectively, thereby achieving juicing. During the juicing process, the fruit can exert an upward reaction force on the screw body 220, so that the screw body 220 has a tendency to move upward. The user can move the adjustment component 300 to connect the limiting structure, which can limit the axial movement of the screw body 220 along the connecting shaft 210, so as to avoid the situation where the screw body 220 is lifted by the fruit during juicing, resulting in the inability to squeeze juice. The traditional technical solution of using the cover body to abut the upper end of the screw body 220 can be abandoned to improve the taste of food.

[0038] It should be noted that when cleaning the juice extraction component 200, the user can move the adjustment component 300 in the reverse direction to disconnect the limiting structure. The user can remove the screw body 220 and the connecting shaft 210 from the juice extraction chamber 110 to clean the cup body component 100 and the juice extraction component 200 respectively, which can enhance the user experience and is not described in detail here.

[0039] It should be noted that the screw body 220 and the connecting shaft 210 can be integrally formed by a mold to increase the connection strength between the screw body 220 and the connecting shaft 210, which can improve the reliability of the juicer, which will not be described in detail here.

The limiting member 400 can abut against the side wall of the limiting groove 211, thereby limiting the axial movement of the screw body 220 along the connecting shaft 210. When disassembling the juice extraction component 200, the user can move the adjusting component 300 in the reverse direction so that one end of the limiting member 400 exits the limiting groove 211, thereby disconnecting the limiting member 400 from the connecting shaft 210, and the user can separate the juice extraction component 200 from the cup body component 100. The operation is simple, convenient and fast, and the juice extraction component 200 can be easily installed and disassembled.

The two limit members 400 are symmetrically arranged along the circumference of the connecting shaft 210. When the limit structure is connected, one end of the two limit members 400 is inserted into the limit groove 211, which can prevent the screw body 220 from shaking left and right, thereby improving the juicing efficiency of the juicer. It will not be described in detail here.

[0051] Specifically, the second transmission part 311 is arranged along the circumference of the adjusting member 310. When the adjusting member 310 rotates, the second transmission part 311 can abut against the first transmission part 410 to push the first transmission part 410 to move in a direction away from the limiting groove 211, which can facilitate the disconnection of the limiting structure, thereby making it convenient for users to disassemble the juice extraction assembly 200 and clean the cup body assembly 100 and the juice extraction assembly 200.

[0052] It should be noted that the transmission structure can also be a gear rack transmission structure, the gear is arranged on the adjusting member 310, the rack is arranged on the limiting member 400, the gear and the rack are meshed, and can also drive the limiting member 400 to move in a direction away from the limiting groove 211, which is not limited here.

By setting a pulling member 330, the user can rotate the pulling member 330 to drive the adjusting member 310 to rotate, so as to connect or disconnect the limiting structure, which can facilitate the installation and disassembly of the juicing assembly 200.

[0058] It should be noted that the seat body 102 is detachably connected to the cup body 101 by bolting or clamping, so as to facilitate the assembly of the adjustment component 300 and the limiter 400, which will not be described in detail here.

[0059] It should be noted that the adjusting member 310 and the pulling member 330 are an integrated structure, which can reduce the number of molds, thereby reducing the production cost of the molds, thereby reducing the production cost of the juicer, which will not be described in detail here.
