Description

Technical Field

[0001] This utility model relates to a juicer component, and more specifically, to a juicer screw sealing structure. Background Technology

[0002] The screw is the core component of a juicer. Currently, there are two main types of screws: solid and hollow. In practical use, it has been found that when a hollow screw is juicing, food particles easily enter the annular, sealed space inside the screw through the gap between the screw and the cup. With continued operation, the amount of particle material increases, and the particles inside are compressed and piled up, making subsequent cleaning and rinsing difficult. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the prior art by providing a juicer screw sealing structure that is compact, easy to clean, and performs well.

[0004] The technical solution of this utility model is implemented as follows: a juicer screw sealing structure includes a screw, and a connecting post with a built-in drive shaft is provided axially at the bottom of the screw. An annular sealing cover is provided between the lower end of the connecting post and the inner wall of the screw.

[0005] In the aforementioned juicer screw sealing structure, several reinforcing ribs are distributed circumferentially in the environmental space between the connecting column and the inner wall of the screw, and the annular sealing cover plate is fixedly connected to the reinforcing ribs by screws.

[0006] In the aforementioned juicer screw sealing structure, the outer edge of the lower end face of the annular sealing cover plate is interference-fitted with the inner wall of the screw, and the inner edge is interference-fitted with the outer wall of the connecting column.

[0007] In the above-mentioned juicer screw sealing structure, the lower end face of the reinforcing rib is provided with a boss, and a connecting hole is provided at the center of each boss. The upper end face of the annular sealing cover is provided with a connecting groove corresponding to each boss. A clearance hole corresponding to the connecting hole is provided at the center of the connecting groove. The screw passes through the clearance hole and is threadedly connected to the connecting hole.

[0008] In the aforementioned juicer screw sealing structure, the screw is a countersunk screw, and a countersunk hole that mates with the countersunk screw is formed on the lower end face of the annular sealing cover plate. A sealing ring is provided between the countersunk hole and the countersunk screw.

[0009] By adopting the above structure, this utility model provides an annular sealing cover between the lower end of the connecting ring and the inside of the screw. The annular sealing cover completely seals the annular space inside the screw, making it completely sealed. This effectively prevents residue from entering the annular space during juicing, thus avoiding the problem of subsequent cleaning difficulties. Attached Figure Description

[0016] See Figures 1 to 4 As shown, this utility model discloses a juicer screw sealing structure, including a screw 1, with a connecting post 2 having an internal drive shaft arranged axially at the bottom of the screw 1. The connecting post is preferably integrally injection molded with the screw, and the drive shaft is preferably a metal shaft fixed inside the connecting post. This can be achieved by screws or by fixing the screw inside during injection molding, which is common knowledge in the art and will not be elaborated further. When the screw is large, this hollow structure is primarily used to save materials and reduce costs. An annular sealing cover 3 is provided between the lower end of the connecting post 2 and the inner wall of the screw 1. The annular sealing cover completely seals the annular space surrounding the connecting post, making it a completely sealed annular space and effectively preventing debris from entering.

[0017] Preferably, a plurality of reinforcing ribs 4 are distributed circumferentially at intervals within the environmental space between the connecting post 2 and the inner wall of the screw 1, and the annular sealing cover 3 is fixedly connected to the reinforcing ribs 4 by screws 5. Of course, based on the above concept, the annular sealing cover can also be fixed to the screw and connecting post using other methods conventional in the art, such as ultrasonic welding or bonding. These are equivalent alternatives that are easily conceived by those skilled in the art.

[0018] More preferably, the outer edge of the lower end face of the annular sealing cover 3 is interference-fitted with the inner wall of the screw 1, and the inner edge is interference-fitted with the outer wall of the connecting post 2. With this structure, there is no gap at the contact points between the annular sealing cover, the screw, and the connecting post, which avoids the problem of debris remaining in the tiny gaps and causing difficulty in cleaning.

[0019] More preferably, the lower end face of the reinforcing rib 4 is provided with a boss 4a, and a connecting hole 4b is provided at the center of each boss 4a. The upper end face of the annular sealing cover plate 3 is provided with a connecting groove 3a corresponding to each boss 4a, and a clearance hole 3b corresponding to the connecting hole 4b is provided at the center of the connecting groove 3a. The screw 5 passes through the clearance hole 3b and is threadedly connected to the connecting hole 4b. This structure facilitates the alignment and connection of the annular sealing cover plate and the reinforcing rib, and the screw position can be sealed by the cooperation of the boss and the connecting groove, thereby improving the sealing performance.

[0020] More preferably, the screw 5 is a countersunk screw, and a countersunk hole 3c is formed on the lower end face of the annular sealing cover plate 3 to mate with the countersunk screw 5. A sealing ring 6 is provided between the countersunk hole 3c and the countersunk screw 5. The sealing ring further improves the sealing performance of the screw mounting position.

[0021] By using the aforementioned interference fit and sealing ring, it is possible to effectively prevent residue, extracted juice, and water from entering the space between the screw inner wall and the annular sealing cover 3, thus preventing the occurrence of odors due to prolonged lack of effective cleaning.

[0022] The screw of this invention is used in the same way as a conventional screw.

[0023] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
