Description

Technical Field

[0001] The present application relates to the technical field of juicers, and in particular to a juicer head structure. Background Art

[0002] As a rapid fruit and vegetable juice extraction device widely used in households and commercial fields, juicers have developed a variety of styles and working principles. Among them, patent CN1874694A discloses a small juicer design specifically for small citrus fruits, especially suitable for orange juicing. The core of the juicer lies in its juicing system based on a concave-convex drum, including key components such as a gravity supply ramp, a housing with a protective front cover, a cutting blade, a concave-convex drum, a filter, a juice and peel collection base, and a peel extraction assembly. Its operating mechanism is to cut the fruit into two parts by a cutting blade, and position and squeeze the cut fruit in different cavities of the concave drum to extract the juice, and finally achieve effective separation of the peel to ensure that the squeezed juice does not have the bitter taste of the peel, thereby improving the taste.

[0003] The above-mentioned juicer still has the following two problems:

[0004] First, since juice will remain after juicing, it needs to be cleaned and washed regularly to maintain hygiene. When the juicer is disassembled and washed, the concave-convex drum is locked on the support plate by a fastening shaft, and the fastener needs to be removed with tools before the concave-convex drum can be removed for washing. This is quite inconvenient.

[0005] How to improve the portability of disassembly is a technical problem that needs to be solved urgently. Based on this, the applicant filed a patent application with application number 2023228925277 on October 27, 2023, entitled "A quick-release structure for a juice extracting mechanism", which provides a convenient disassembly and quick-release structure for the juice extractor for easy maintenance and cleaning. At the same time, during the working process, since the rotation direction is opposite to the locking direction, it can be ensured that the two will not separate.

[0006] Secondly, since the convex drum and the concave drum cooperate to squeeze the fruit, both are unidirectional, the degree of squeezing the fruit is not enough, which affects the juice yield. It can also be understood that the squeezed fruit has not been completely squeezed before the squeezing action is ended. In order to improve the juice yield, the applicant also filed an application number 202322892384X on 2023-10-27, entitled A patent application for a connection structure of a juicer head

[0007] However, the integrity of the juice extraction head of this structure is relatively poor, especially the second annular wall of the juice extraction unit is open, which makes it easy for dirt to enter and is not conducive to cleaning.

[0008] In order to achieve the self-rotation of each convex part while improving the structural integrity, which is the purpose proposed by this application, to further improve the above technology. Summary of the invention

[0009] Based on this, the present application provides a juice extraction head structure to improve the above-mentioned defects.

[0011] During operation, the rotation of the rotating support seat drives the connecting seat to rotate synchronously, the main gear remains fixed relative to the connecting seat, and the convex portion rotates synchronously around the rotating shaft under the action of the planetary gear.

[0012] In some embodiments, the main gear is fixed on a secondary support shaft, and the inner end of the secondary support shaft is detachably engaged with the main support shaft via an intermediate connecting piece.

[0013] In some embodiments, a movable sleeve is provided on the connecting seat, and the auxiliary support shaft is fastened to the sleeve.

[0014] In some embodiments, a fastener for fixing the main gear is disposed at an outer end of the secondary support shaft.

[0015] In some embodiments, an outer gear ring is formed on the rotating support seat, and the driving and transmission mechanism includes a motor, a gear or a gear set, and the gear or gear set is meshed with the outer gear ring.

[0016] In some embodiments, the rotating support seat rotates in a first direction, the rotating support seat has a first annular wall, and the connecting seat has a second annular wall;

[0017] The first annular wall is provided with a plurality of position limiting slots, and the second annular wall is provided with a plurality of position limiting strips;

[0018] The limit slot includes an entrance section and a locking section, the entrance section is communicated with the outer edge of the first annular wall, and the locking section is blocked from the outer edge of the first annular wall;

[0019] Wherein, the locking section is the entrance section extending in a second direction, and the second direction is opposite to the first direction;

[0020] The limiting clamping strip enters from the entrance section in a second direction and is locked at the locking section.

[0021] In some embodiments, the protrusions are provided at three locations evenly distributed in an annular shape, and the axial direction of the rotating shaft is kept substantially perpendicular to the axial direction of the main support shaft.

[0022] In some embodiments, the connecting seat covers the main gear and the planetary gears.

[0023] The beneficial effect of the present application is that compared with the prior application, the present application realizes the flexible rotation and effective positioning of the juice extraction head through the design of the main support shaft, the rotating support seat and the connecting seat, and ensures the stability and high efficiency during the juice extraction operation. The overall structure is compact and reasonable, and the consistency is good. BRIEF DESCRIPTION OF THE DRAWINGS
