Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a feeding device for a juicer. Background Technology

[0002] Currently, juicer products use a step-by-step feeding method when juicing. After each feeding, a pusher is used to push the fruit and vegetable chunks into the juicing cup so that they can enter the pressing system for juicing. The structure described above cannot achieve one-time feeding and requires the user to push the material with the pusher, making the operation cumbersome and resulting in a poor user experience.

[0003] Chinese patent document CN202311209198.X disclosed a fruit and vegetable juice extraction device in 2023. Specifically, it discloses a base, a juicing assembly, and a feeding assembly. The juicing assembly includes a juicing shell with a juicing screw inside, and a filter assembly surrounding the screw. The drive mechanism includes a motor assembly and a reducer assembly driven by the motor assembly. The reducer assembly has an inner output shaft and an outer output shaft coaxially arranged at its output end, rotating simultaneously in opposite directions. The juicing screw is coupled to the inner output shaft, and the filter assembly is coupled to the outer output shaft. A cutting blade is rotatably mounted inside the feeding cylinder. In the aforementioned patent document, the cutting blade rotates synchronously with the juicing screw, allowing the fruits and vegetables inside the feeding cylinder to be chopped before entering the juicing assembly through the feeding port. Although this allows for one-time feeding without the need for a pusher, it still results in uneven cutting of the ingredients, leading to uneven sizes of ingredients entering the juicing assembly and potential accumulation of material inside the feeding cylinder.

[0004] Therefore, further improvements are needed. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a feeding device for a juicer to overcome the shortcomings of the prior art, so as to be able to directly cut the ingredients into small pieces, reduce the amount of material stuck in the food, and further improve the juice yield and juicing efficiency.

[0006] A feeding device for a juicer designed for this purpose includes a feeding cylinder and a cutting blade rotating inside the feeding cylinder. The inner wall of the feeding cylinder is provided with a guide structure that guides the food from top to bottom in the direction of centrifugal force toward the cutting blade. The guide structure includes an upper blocking part and a lower blocking part, which are transitionally connected. The cutting blade cooperates with the upper blocking part and the lower blocking part to perform pre-shearing treatment on the food in the feeding cylinder.

[0007] The upper blocking part and the lower blocking part are curved and smoothly connected; The upper blocking part and the lower blocking part form an angle α with the inner wall of the opposite feed cylinder, and the angle α is an obtuse angle.

[0008] The upper blocking portion extends toward the central axis of the cutting tool.

[0009] The upper blocking part and the lower blocking part are staggered vertically on the inner sidewall of the feed cylinder.

[0010] The upper blocking part is inclined inward from top to bottom towards the lower blocking part; the lower blocking part is inclined forward from top to bottom.

[0011] The upper blocking part is provided with guide ribs facing the lower blocking part. There are multiple guide ribs, and the multiple guide ribs are evenly spaced on the end faces of the upper blocking part and the lower blocking part.

[0012] The cutting blade includes an upper cutting blade, the blade of which cooperates with the lower blocking part to cut the food.

[0013] The feed cylinder is provided with a first inclined surface, which is arranged along the inner edge of the circumference of the feed cylinder, and a cutting edge is provided on the first inclined surface; The cutting blade also includes a lower cutting blade that cooperates with the blade edge. The lower cutting blade extends horizontally along the radial direction of the feed cylinder. The outer diameter of the lower cutting blade is close to the inner wall of the feed cylinder. An opening is formed between the bottom of the feed cylinder and the guide structure for the lower cutting blade to pass through. When the lower cutting blade passes through the opening, the lower cutting blade and the blade edge can cut the food again.

[0014] The feed cylinder is provided with a discharge port, and the guide structure is provided corresponding to the discharge port; the guide structure and the feed cylinder are integrally formed or separately formed.

[0015] The feeding device also includes a screw for processing the cut ingredients. The bottom of the feeding cylinder is provided with a second inclined surface. The second inclined surface extends inclinedly outward from the central axis of the feeding cylinder. The screw is provided with a cutting surface corresponding to the second inclined surface. The cutting surface is close to the second inclined surface. The second inclined surface forms an inclination angle b with the central axis of the feed cylinder, where 45°≤b≤85°.

[0016] A feeding device for a juicer according to the above embodiment includes a feeding cylinder and a cutting blade rotating inside the feeding cylinder. The inner wall of the feeding cylinder is provided with a guide structure that guides the food from top to bottom towards the cutting blade in the direction of centrifugal force. The guide structure includes an upper blocking part and a lower blocking part. The end faces of the upper blocking part and the lower blocking part are curved and smoothly connected. The cutting blade cooperates with the upper blocking part and the lower blocking part to perform pre-shearing treatment on the food in the feeding cylinder. Specifically, the guide structure allows the food to be subjected to centrifugal force inside the feeding cylinder, thereby guiding it from top to bottom towards the cutting blade. This helps to evenly feed the food into the cutting blade for pre-cutting treatment. The curved end faces of the upper blocking part and the smooth transition ensure that the food does not encounter unnecessary resistance during the guiding process, thus allowing it to be evenly fed into the cutting blade for pre-cutting treatment. This enables the food to be directly cut into small pieces, reducing the possibility of food accumulation and improving the juice yield and efficiency. It also reduces the stagnation and blockage of food in the feeding cylinder, thereby ensuring smooth juicing. Attached Figure Description

[0027] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0028] First embodiment: as follows Figures 1-6 As shown, a feeding device for a juicer is provided, including a feeding cylinder 1 and a cutting blade 2 rotating inside the feeding cylinder 1. The inner side wall of the feeding cylinder 1 is provided with a guide structure 3 that guides the food from top to bottom towards the cutting blade 2 in the direction of centrifugal force. The guide structure 3 includes an upper blocking part 301 and a lower blocking part 302, which are connected by a transition. The cutting blade 2 cooperates with the upper blocking part 301 and the lower blocking part 302 to perform pre-shearing treatment on the food in the feeding cylinder 1.

[0029] Specifically, the guide structure 3 allows the food to be subjected to centrifugal force within the feed cylinder 1, guiding it from top to bottom towards the cutting blade 2. This helps to evenly feed the food into the cutting blade 2 for pre-cutting. The upper blocking part 301 and the lower blocking part 302 are connected to ensure that the food is not subjected to unnecessary resistance during the guiding process, thus allowing it to be evenly fed into the cutting blade 2 for pre-cutting. This enables the food to be directly cut into small pieces, reducing the possibility of food accumulation and improving the juice yield and efficiency. It also reduces the stagnation and blockage of food within the feed cylinder 1, ensuring smooth juicing.

[0030] Furthermore, such as Figure 1 As shown, the upper blocking part 301 and the lower blocking part 302 are curved and smoothly connected, which ensures that the food will not be subjected to unnecessary resistance during the guiding process, so that it can be evenly fed into the cutting blade 2 for cutting pretreatment.

[0031] Furthermore, such as Figure 1As shown, the upper blocking part 301 and the lower blocking part 302 form an angle α with the inner wall of the opposite feed cylinder 1, and the angle α is an obtuse angle.

[0032] Specifically, the obtuse angle α ensures that the food passes smoothly during the guiding process and prevents the food from getting stuck or squeezed between the guide structure 3 and the inner wall of the feed cylinder 1. At the same time, the obtuse angle α allows the guide structure 3 to more effectively guide the food into the area of ​​the cutting blade 2, thereby improving the accuracy and efficiency of cutting.

[0033] Furthermore, such as Figure 3 As shown, the upper blocking part 301 extends toward the central axis of the cutting tool 2.

[0034] Specifically, from a top-down view, the upper blocking part 301 of the guide structure 3 extends toward the central axis of the cutting blade 2, which can better guide the food toward the cutting area of ​​the cutting blade 2, thereby enabling more effective cutting and efficient food pretreatment.

[0035] Furthermore, such as Figure 3 As shown, the upper blocking part 301 and the lower blocking part 302 are staggered in the vertical direction on the inner side wall of the feed cylinder 1.

[0036] Specifically, the upper blocking part 301 is responsible for pushing the food towards the cutting blade 2, while the lower blocking part 302 can prevent the food from excessively accumulating or gathering inside the feed cylinder 1, thereby ensuring that the food can be uniformly guided towards the cutting blade 2 under the action of the guide structure 3. This staggered arrangement can improve the efficiency of food cutting and reduce the problem of uneven cutting or clogging caused by food accumulation, thereby improving the juicing efficiency and juice yield.

[0037] Furthermore, such as Figure 2 and Figure 4 As shown, the upper blocking part 301 is gradually inclined inward from top to bottom towards the lower blocking part 302; the lower blocking part 302 is gradually inclined forward from top to bottom.

[0038] Specifically, the upper blocking part 301 is gradually inclined inward from top to bottom towards the lower blocking part 302, so that the food is pushed and gradually approaches the cutting blade 2, which is conducive to smoothly entering the cutting area of ​​the cutting blade; while the lower blocking part 302 is gradually inclined forward from top to bottom, ensuring that after the food passes through the lower blocking part 302, the lower blocking part 302 and the cutting blade 2 can perform shearing pretreatment on the food, thereby improving the efficiency and quality of juicing.

[0039] Furthermore, such as Figure 1 As shown, the cutting blade 2 includes an upper cutting blade 201, the blade of which cooperates with the lower blocking part 302 to cut the food.

[0040] Specifically, as the ingredients fall from the upper blocking part 301 to the lower blocking part 302, the lower blocking part 302 cooperates with the blade of the upper cutting blade 201 to gradually cut the ingredients into small pieces, ensuring that the ingredients are further refined to better meet the requirements of juicing. This staged cutting design helps to ensure that the ingredients are processed evenly and further improves the efficiency and quality of juicing.

[0041] Furthermore, such as Figure 1 , Figure 4 and Figure 5 As shown, the feed cylinder 1 is provided with a first inclined surface 101, which is arranged along the inner edge of the circumference of the feed cylinder 1, and a cutting edge 4 is provided on the first inclined surface 101.

[0042] Specifically, before the food enters the screw 6, the food comes into contact with the blade 4 under the action of centrifugation, which further cuts the food. This helps to reduce the accumulation and jamming of the food during the feeding process, and improves the stability and reliability of the juicer.

[0043] Furthermore, such as Figure 2 and Figure 5 As shown, the cutting blade 2 also includes a lower cutting blade 202 that cooperates with the cutting edge 4. The lower cutting blade 202 extends horizontally along the radial direction of the feed cylinder 1. The outer diameter of the lower cutting blade 202 is close to the inner wall of the feed cylinder 1. An opening 5 is formed between the bottom of the feed cylinder 1 and the guide structure 3 for the lower cutting blade 202 to pass through. When the lower cutting blade 202 passes through the opening 5, the lower cutting blade 202 and the cutting edge 4 can cut the food again.

[0044] Specifically, when the lower cutting blade 202 passes through the opening 5, the lower cutting blade 202 and the blade 4 will cut the food again; this design ensures that the food is fully cut during the feeding process, improving juicing efficiency and juice yield.

[0045] Furthermore, such as Figure 1 As shown, the feed cylinder 1 is provided with a discharge port 102, and the guide structure 3 is provided corresponding to the discharge port 102; the guide structure 3 and the feed cylinder 1 are integrally formed or separately formed.

[0046] Specifically, the guide structure 3 is positioned corresponding to the discharge port 102, ensuring that the chopped ingredients can be smoothly discharged from the discharge port 102, further improving the ease of operation and juice extraction efficiency of the juicer. When the guide structure 3 and the feeding cylinder 1 are integrally formed, the guide structure 3 and the feeding cylinder 1 are processed simultaneously. In this case, the guide structure 3 is part of the feeding cylinder 1, and there is no need to connect the guide structure 3 and the feeding cylinder 1 during assembly, thereby simplifying the assembly steps and effectively improving the assembly efficiency. When the guide structure 3 and the feeding cylinder 1 are separate formed structures, the guide structure 3 and the feeding cylinder 1 are manufactured separately, and then connected and fixed by riveting, welding or screw connection, which facilitates manufacturing and installation and solves the problem of difficult demolding of the feeding cylinder 1 and the guide structure 3.

[0047] Furthermore, such as Figure 6 As shown, the feeding device also includes a screw 6 for processing the cut ingredients. The bottom of the feeding cylinder 1 is provided with a second inclined surface 103. The second inclined surface 103 extends inclinedly outward from the central axis of the feeding cylinder 1. The screw 6 is provided with a blade 601 corresponding to the second inclined surface 103. The blade 601 is close to the second inclined surface 103.

[0048] Specifically, the close proximity of the blade 601 to the second inclined surface 103 prevents material buildup; it ensures that the cut ingredients will not remain at the bottom of the feeding cylinder during the feeding process, but will be promptly carried away by the screw 6, thereby avoiding material accumulation and jamming, and improving the stability and reliability of the juicer.

[0049] Furthermore, such as Figure 6 As shown, the second inclined surface 103 forms an inclined angle b with the central axis of the feed cylinder 1, where 45°≤b≤85°.

[0050] Preferably, the range of tilt angle b may include 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, or 85°.

[0051] Second embodiment: as follows Figure 7 and Figure 8 As shown, the feeding device used in this juicer differs from the first embodiment in that: Furthermore, both the upper blocking part 301 and the lower blocking part 302 are provided with guide ribs 303. There are multiple guide ribs 303, and the multiple guide ribs 303 are evenly spaced on the end faces of the upper blocking part 301 and the lower blocking part 302.

[0052] Specifically, multiple guide ribs 303 are provided, and the multiple guide ribs 303 are arranged vertically at intervals, or horizontally at intervals, or staggered at intervals. The guide rib 303 serves two purposes: firstly, it improves the connection reliability between the upper blocking part 301 and the lower blocking part 302; secondly, it guides the food along the correct path to prevent the food from getting blocked or stuck.

[0053] Other undescribed parts are the same as in the first embodiment.
