Description

Technical Field

[0001] The present application relates to the technical field of juicers, and in particular to a linkage feeding mechanism of a juicer. 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] In order to realize the supply and feeding of fruits, reference can be made to the above-mentioned patent. Figure 3 As shown, a feeder with a fruit detection system is also provided, which allows the juicer to start automatically and prevent clogging.

[0004] However, although the automatic fruit supply method in the prior art realizes the functions of automatic start-up and blocking prevention, this design that relies on signal detection and circuit control increases production costs and may lead to a relatively high failure rate. Summary of the invention

[0005] Based on this, the present application provides a linkage feeding mechanism for a juicer, which improves the above-mentioned shortcomings.

[0006] The technical solution adopted by the present application to solve the technical problem is: a linkage feeding mechanism of a juicer, comprising: a body; a conveying channel, arranged on the body, for storing and conveying fruits to be squeezed; a conveying port, communicating with the conveying channel; a concave rotating member and a convex rotating member cooperating with each other, the concave rotating member is provided with a plurality of concave parts, the convex rotating member is provided with a plurality of convex parts, the concave rotating member and the convex rotating member rotate synchronously, so that one of the convex parts is temporarily accommodated in one of the concave parts, squeezing the fruits and squeezing the juice; a first driving gear, connected to the concave rotating member, for driving the concave rotating member; a second driving gear, connected to the convex rotating member and meshing with the first driving gear, for driving the convex rotating member;

[0007] It also includes: a third driving gear meshing with the second driving gear; a movable baffle movably disposed on the machine body, used to block or open the delivery port;

[0008] Wherein, the third driving gear is provided with a linkage mechanism for actively or indirectly driving the movable baffle to move;

[0009] During operation, the rotation of the first driving gear can drive the third driving gear to rotate, thereby driving the linkage mechanism to control the movable baffle to intermittently block or open the conveying port, so that the fruit can enter one of the recesses of the concave rotating member.

[0010] In some embodiments, the linkage mechanism comprises:

[0011] an outer cam structure formed on the third driving gear, a linkage rod formed at the end of the movable baffle, and a spring for applying the linkage rod to the movable baffle to always resist the outer cam structure;

[0012] The outer cam structure is controlled by the rotation of the third driving gear to resist the longitudinal movement of the linkage rod together with the movable baffle.

[0013] In some embodiments, the linkage mechanism comprises:

[0014] an inner cam structure formed on the third driving gear, a linkage rod formed at the end of the movable baffle, and a spring or tension spring for applying the linkage rod to the movable baffle to always connect the inner cam structure;

[0015] Wherein, the linkage rod comprises a limiting column, and the limiting column hooks and pulls the inner wall of the inner cam structure, and controls the inner cam structure through the rotation of the third driving gear to drive the linkage rod together with the movable baffle to move longitudinally.

[0016] In some embodiments, the linkage mechanism comprises:

[0017] A crank connecting rod connected to the third driving gear, a linkage rod formed at the end of the movable baffle, and a limit block for limiting the movable baffle to only maintain longitudinal movement;

[0018] The end of the linkage rod is connected to the crank connecting rod, and the crank connecting rod is controlled by the rotation of the third driving gear to drive the linkage rod and the movable baffle to move longitudinally.

[0019] In some embodiments, limiting columns are provided on both sides of the movable baffle, and the lower end of the spring is sleeved on the limiting columns.

[0020] In some embodiments, the external cam structure includes a group of symmetrical protrusions and a group of symmetrical concave portions.

[0021] In some embodiments, the inner cam structure includes a group of symmetrical protrusions and a group of symmetrical concave portions.

[0022] In some embodiments, the concave parts are evenly distributed in a ring shape at 4 locations, and the convex parts are evenly distributed in a ring shape at 3 locations; the gear ratio between the first drive gear and the third drive gear is 1:1, and the gear ratio between the first drive gear and the second drive gear is 4:3; so that when the concave rotating part rotates half a circle, the movable baffle opens the conveying port.

[0023] The beneficial effect of the present application is that the transmission between multiple gears cooperates with a linkage mechanism to drive the movable baffle to block or open the conveying port at a specific position, thereby realizing automatic feeding of fruits. The purely mechanical mechanism only requires one power source, and its structure is more stable and reliable, with a low failure rate, and is conducive to reducing production costs.

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.

[0030] Reference Figure 1 As shown, a linkage feeding mechanism of a juicer is provided, which mainly includes components such as a body 1, a conveying channel 2, a conveying port 3, a concave rotating member 4, a convex rotating member 5, a first driving gear 6, a second driving gear 7 and a movable baffle 9. The conveying channel 2 is arranged in the upper area of ​​the body 1, and is used for temporarily storing and transmitting the fruit to be squeezed; the conveying port 3 is connected with the conveying channel 2; the concave rotating member 4 and the convex rotating member 5 cooperate with each other, and a plurality of concave parts 41 are distributed on the concave rotating member 4, and a plurality of convex parts 51 are arranged on the convex rotating member 5. When the two rotate synchronously, a convex part 51 will be embedded in a certain concave part 41 to squeeze the fruit and extract juice. The first driving gear 6 is connected to the concave rotating member 4, driven by a motor gear, and is responsible for driving the concave rotating member 4; the second driving gear 7 is connected to the convex rotating member 5, and meshes with the first driving gear 6 to drive the convex rotating member 5.

[0031] In addition, it also includes a third driving gear 8, which is meshed with the second driving gear 7 and is equipped with a linkage mechanism 10, which can actively or indirectly drive the movable baffle 9 to move on the body 1. The function of the movable baffle 9 is to intermittently open or block the delivery port 3 to control the fruit to enter the concave portion 41 of the concave rotating member 4 for juicing.

[0032] Regarding the specific form of the linkage mechanism 10 , there are many possible implementation schemes.

[0033] For example, in one embodiment, referring to Figure 1 The linkage mechanism 10 includes: an outer cam structure 11 arranged on the third driving gear 8, a linkage rod 91 arranged at the end of the movable baffle 9, and a spring (not shown in the figure) that ensures that the linkage rod 91 always contacts the outer cam structure 11. When the third driving gear 8 rotates, the linkage rod 91 and the movable baffle 9 are pushed to move longitudinally by the outer cam structure 11. Among them, the outer cam structure 11 is designed as a symmetrical combination of a convex portion 51 and a concave portion 41, shaped like an 8-shaped structure. In order to keep the movable baffle 9 always in a downwardly abutting state, limit columns 92 can be set on both sides of the baffle, the lower end of the spring is sleeved on the limit columns 92, and the upper end is pressed against a specific part of the body 1. Thereby, the movable baffle 9 is always pressed downward by the spring, for example, the outer cam structure 11 is rotated to different positions to control the longitudinal height of the movable baffle 9.

[0034] In another embodiment, referring to Figure 2 The linkage mechanism 10 adopts the design of the inner cam structure 12, the linkage rod 91 and the spring (or tension spring). The end of the linkage rod 91 hooks the inner wall of the inner cam structure 12 through the limit column 92. When the third driving gear 8 rotates, the linkage rod 91 and the movable baffle 9 are driven to move longitudinally through the inner cam structure 12. The inner cam structure 12 also has symmetrical convex parts 51 and concave parts 41, forming an 8-shaped structure.

[0035] In another optional embodiment, referring to Figure 3 The linkage mechanism 10 is composed of a crank connecting rod 13 connected to the third driving gear 8, a linkage rod 91 at the end of the movable baffle 9, and a limit block that limits the movable baffle 9 to only move longitudinally. The end of the linkage rod 91 is connected to the crank connecting rod 13. When the third driving gear 8 rotates, the crank connecting rod 13 drives the linkage rod 91 and the movable baffle 9 to move longitudinally.

[0036] Preferably, the concave portions 41 on the concave rotating member 4 are distributed in 4 locations evenly distributed in a ring shape, and the convex portions 51 on the convex rotating member 5 are distributed in 3 locations evenly distributed in a ring shape; the gear ratio between the first drive gear 6 and the third drive gear 8 is set to 1:1, and the gear ratio between the first drive gear 6 and the second drive gear 7 is 4:3. This configuration allows the movable baffle 9 to open the delivery port 3 once every half turn of the concave rotating member 4.

In order to avoid obscuring the concept of the present application, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed herein.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present application, and the aforementioned embodiments are only used to illustrate the technical solution of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein.
