When the locking lever (220) is raised, the ends of the opening guide part (226) and the ring part (227) come into close contact with or come into contact with the outer surface of the locking part (208). When the hopper (150) continues to rotate in the locking direction, the ends of the opening guide part (226) and the ring part (227) pass through the outer surface of the locking part (208) and move to the ends of the locking part (208).

[0123] Additionally, when the locking guide (224) comes into contact with and is pressed against one side of the catch (208) during the step where the hopper is secured (lowering of the fixing part), the side of the locking guide (224) and the side of the catch (208) are aligned parallel to each other, and the locking lever (220) is rotated around the pivot axis (223) so that the locking lever (220) moves toward the catch (208).

[0124] Next, in the hopper locking step, when the locking lever (220) moves toward the catch portion (208), the catch portion (208) is received in the fixing groove (228), and the hopper (150) is locked while the hook portion (227) and the locking guide portion (224) support one side of the catch portion.

[0125] Additionally, the locking lever (220) may be moved to the end of the locking part (208) so as to be spaced apart from the outer surface of the locking part (208) and the juice drum (100) to enable locking.

[0126] Referring to FIGS. 14 and 15 when unlocking, the locking lever (220) is unlocked by operating the gripping portion (225) of the locking lever (220) or the gripping portion (255) of the release lever (250), causing the locking lever (220) to move apart.

[0127] That is, unlocking via the locking lever (220) is achieved when the user presses the gripping part (225), causing the locking lever (220) to move outward from the locking part (208) relative to the rotation axis (223), and unlocking via the release lever (250) is achieved when the user rotates the gripping part (255), causing the release guide part (256) to slide the release support part (229), thereby causing the locking lever (220) to move outward from the locking part (208).

[0128] Additionally, the gripping portion (255) formed on the release lever (250) allows the user to unlock the handle (170) of the hopper (150) by pressing the gripping portion (255) with their fingertip while gripping the handle, thereby enabling the unlocking of the hopper (150) and the gripping of the hopper (150) to occur sequentially.

[0129] FIGS. 16 to 19 are drawings showing a third embodiment of a locking part of a juicer according to the present invention.

[0130] The locking part (200) of this embodiment is composed of a locking lever (230) and a locking part (208).

[0131] The locking lever (230) includes an opening guide (236), a ring portion (237), a fixing groove (238), a locking guide (234), a groove portion (233a), a pivot shaft (233), an extension portion (235a), and a gripping portion (235).

[0132] The locking lever (230) is rotatably supported by a pivot shaft (233) inserted into a fastening part (233b) formed in the hopper (150).

[0133] The opening guide (236) is formed as an inclined surface having a certain angle.

[0134] The inclined surface is formed so that when the locking part (208) enters, the locking lever (230) slides and rises.

[0135] The inclined surface can be formed in various shapes, such as a straight inclined surface, a curved surface, or an arc shape.

[0136] The loop portion (237) is formed on one side of the fixing groove (238) and can be formed as a vertical or inclined surface to support the side of the catch portion (208).

[0137] The loop portion (237) can be formed in a shape corresponding to the hook portion (208).

[0138] The fixing groove (238) is formed in a corresponding shape so that the locking part (208) can be received.

[0139] The fixed groove (238) can be formed through or in a shape that is only carved out on one side.

[0140] The locking guide (234) is formed on one side of the fixing groove (238).

[0141] The locking guide (234) is formed in a shape corresponding to the side of the locking part (208), and when pressed by the locking part (208), the locking lever (230) rotates about the pivot axis (233) so that the fixing groove (238) is caught on the locking part (208).

[0142] The extension portion (235a) is formed to extend from one side of the locking lever (230) to the gripping portion (235).

[0143] The extension part (235a) may be formed integrally with the locking lever (230) or extended by being combined with a fastening structure.

[0144] The gripping portion (235) is formed to extend upward and to one side of the extension portion (235a).

[0145] It is configured so that when the user grips the handle of the hopper, the fingertip or the outer side of the hand comes into contact with the gripping part (235), and the locking lever (230) is naturally pressed and unlocked.

[0146] The gripping portion (235) can be inclined at a certain angle or formed in various shapes such as curved, arc-shaped, or circular.

[0147] The catch portion (208) may be formed protruding from one side of the juice drum and may be formed in a shape corresponding to the fixing groove (238), the ring portion (237), and the locking guide portion (234).

[0148] The locking portion (208) may include a locking support portion (209) protruding downward, and the locking support portion (209) is configured to support an external force by contacting the locking guide portion (234).

[0149] Referring to FIGS. 17 to 19, the operation process can be observed, and in this embodiment, the locking structure can be implemented as follows.

[0150] FIG. 17(a) is a step in which the hopper is seated on the juice drum. When the hopper (150) is seated on the juice drum (100), the locking lever (230) may be positioned so as to be close to the outer wall of the hopper (150) or spaced apart from the outer surface of the juice drum (100), or may be maintained in a close and spaced state.

[0151] FIG. 17(b) is the step of the hopper being secured (locking lever rising). When the hopper (150) is rotated in the locking direction to secure the hopper (150), the opening guide (236) formed on the locking lever (230) comes into contact with the locking support (209) formed on the catch (208), and the locking lever (230) is lifted by sliding movement due to the inclined surface formed on the opening guide (236).

[0152] FIG. 17(c) is the step in which the hopper is secured (fixing part transfer). When the locking lever (230) is raised, the ends of the opening guide part (236) and the ring part (237) come close to or come into contact with the outer surface of the locking part (208). When the hopper (150) continues to rotate in the locking direction, the ends of the opening guide part (236) and the ring part (237) move to the ends of the locking part (208) while passing through the outer surface of the locking part (208).

[0153] In addition, in another embodiment, the locking lever (230) may be moved toward the locking part (208) while spaced apart from the outer surface of the juice drum (100).

[0154] Next, in the step of the hopper being secured (lowering of the fixed part), as shown in FIG. 17, when the locking guide part (234) is pressed against one side of the locking part (208), the side of the locking guide part (234) and the side of the locking part (208) are aligned parallel to each other, and the locking lever (230) is rotated about the pivot axis (223), thereby moving the locking lever (230) toward the locking part (208).

[0155] Next, in the hopper locking step, when the locking lever (230) moves toward the catch portion (208), the catch portion (208) is received in the fixing groove (238), and the hopper (150) is locked while the hook portion (237) and the locking guide portion (234) support one side of the catch portion (208).

[0156] FIGS. 18 and 19 show the hopper unlocking step (grip part operation step), in which when the grip part (235) is pressed, the locking lever (230) connected to the grip part (235) is separated to the outside of the locking part (208) and the lock is released.

[0157] The unlocking is characterized by the user being able to unlock the gripper (235) by pressing it directly, or by the user pressing the gripper (235) with their fingertips or the outer side of their hand while gripping the handle of the hopper (150), thereby naturally unlocking the hopper and allowing it to be separated.

[0158] Therefore, according to the present invention, it has the effect of preventing the hopper from detaching due to the reverse torque generated during juicing.

[0159] In addition, according to the present invention, the fixed part has the effect of enabling intuitive operation through a sliding structure linked to it.

[0160] Although specific embodiments of the juicer according to the present invention have been described so far, it is obvious that various modifications are possible within the scope of the present invention.

[0161] Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.

[0162] That is, the aforementioned embodiments should be understood as exemplary in all respects and not limiting, and the scope of the invention is defined by the claims set forth below rather than by the detailed description, and all modifications or variations derived from the meaning and scope of the claims and their equivalents should be interpreted as being included within the scope of the invention.
