Description

Technical Field

[0001] The utility model relates to the field of juicers, in particular to a juicer that prevents juice from leaking. Background Art

[0002] The juicing attachment that comes with the current screw-type multi-functional meat grinder is prone to leaking juice when it is reversed. The specific reason is that when the screw reverses, it pushes the ingredients in the opposite direction, which will push the juice in the juicer in the opposite direction. The liquid will easily flow into the body, causing the juice to overflow and leak into the body connector, causing liquid to accumulate in the body. These accumulated liquids are difficult to clean, and over time, problems such as odor will occur, and may even cause damage to electronic components such as motors.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0018] Please see attached Figure 1-3 The present application provides a leakage-proof juicer, comprising a body 1, a juicing screw 2 and a transmission mechanism. The juicing screw 2 is arranged inside the body 1, and the transmission mechanism is used to drive the juicing screw 2 to rotate. The transmission mechanism includes a wear-resistant part 3, a transmission sleeve 4 and a sealing ring 5. The wear-resistant part 3 is fixed inside the body 1 and abuts against the juicing screw 2. The wear-resistant part 3 has an axial connection part 6 that passes through the body 1 and communicates with the outside world. The transmission sleeve 4 is arranged inside the body 1 and is connected for transmission with the juicing screw 2. The transmission sleeve 4 is rotatably connected to the axial connection part 6 and has a connecting end 7 that extends out of the axial connection part 6. Specifically, the outer wall of the transmission sleeve 4 contacts and rotates with the inner wall of the axial connection part 6. The transmission sleeve 4 has an annular pressure edge 8, which presses the sealing ring 5 on the wear-resistant part 3. This solution reduces the direct wear of the juicing screw 2 on the body 1 by setting a wear-resistant part 3 to abut against the juicing screw 2, thereby extending the service life. The transmission sleeve 4 is rotatably connected to the axial connection part 6 of the wear-resistant part, and cooperates with the annular pressure edge 8 to compress the sealing ring 5 to form a double seal, namely axial compression and radial rotation seal, which effectively prevents juice from leaking from the transmission mechanism.

[0019] The wear-resistant part 3 is provided with an annular recess 9, and the sealing ring 5 is placed on the annular recess 9. The annular recess 9 provides a precise positioning space for the sealing ring 5, ensuring that the sealing ring fails evenly under pressure, while reducing the wear of the sealing ring, improving the durability of the seal, and avoiding local sealing caused by installation deviation.

[0020] The transmission sleeve 4 is connected to the juicing screw 2 through the transmission shaft 10. The juicing screw 2 and the transmission sleeve 4 are provided with a shaft connection hole 11 for the transmission shaft 10 to cooperate with the connection. The cross-section of the transmission shaft 10 is non-circular. Specifically, the cross-section of the transmission shaft 10 is one of a triangle, a rectangle, a pentagon, a hexagon, and an ellipse, so that the user can disassemble and clean the juicing screw and the transmission shaft later.

[0021] The connecting end 7 is fixed with a coupling device 13 by a screw 12. The coupling device 13 and the connecting end are connected with screws, which has the advantage of easy disassembly and assembly, and is convenient for later disassembly and maintenance. In addition, the coupling device 13 can prevent the connecting end 7 from being directly connected to the drive source. The coupling device will wear during use. When the coupling device 13 is worn to the point that it can no longer provide normal transmission function, it can be replaced by removing the screws.

[0022] The juicing screw 2 is provided with an annular abutment cavity, and the wear-resistant part 3 has an annular protrusion 14 abutting against the abutment cavity, ensuring the stability of the juicing screw during rotation and avoiding excessive friction caused by full contact between the juicing screw and the wear-resistant part.

[0023] The other end of the body 1 relative to the transmission mechanism is provided with a cover 15, which is detachably connected to the body 1. The cover 15 is provided with a slag outlet 16, so that the user can disassemble and clean the internal components of the body after each use of the juicer.

[0024] A juice outlet 17 is provided at the bottom of the body 1 corresponding to the front end of the juicing screw 2, and a feed port 18 is provided at the top of the body 1 corresponding to the rear end of the juicing screw 2. The feed port 18 and the juice outlet 17 are respectively arranged at both ends of the juice screw to optimize the juice flow path and avoid juice backflow. A filter 19 is provided inside the body 1, and a recess is provided on the filter 19. A convex portion is provided inside the body 1 to cooperate with the recess. With the cooperation of the convex portion and the recess, the filter 19 can be fixed inside the body 1, so that the filter 19 cannot move relative to the body 1. An opening is provided at the front end of the filter 19 corresponding to the residue outlet. The juicing screw is provided on the inner side of the filter 19, and a juicing area is formed between the outer surface of the juicing screw and the filter 19. When the juice is squeezed out of the fruits and vegetables placed in the body, the juice passes through the filter under the action of gravity and is discharged from the juice outlet, while the fruit and vegetable residues are squeezed by the juicing screw and continue to move forward along the juicing area and through the opening at the front end, and are finally discharged from the residue outlet 16.

[0025] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
