Description

Technical Field

[0001] The utility model relates to the technical field of juicers, in particular to a centrifugal fruit juicer. Background Art

[0002] As people pursue a healthier lifestyle, fruit juicers, as an important appliance in the home kitchen, have become the focus of consumers for their performance and convenience. However, the fruit juicers currently on the market still have certain limitations in design and function, which affects the user experience.

[0003] Traditional fruit juicers often require users to manually press the juicer barrel to ensure a tight seal and stability during the juicing process. This operation is not only cumbersome but can also cause hand fatigue and affect juicing efficiency. Furthermore, traditional juicers typically require users to pre-load the juicer barrel with fruit, making it impossible to continuously add fruit during the juicing process, limiting the flexibility and continuity of juicing.

[0004] On the other hand, traditional juicers often have difficulty effectively separating juice and pomace during juicing, resulting in juice containing a lot of pomace and impurities, affecting the taste and quality of the juice. This not only reduces user satisfaction but also has potential health risks. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a centrifugal fruit juicer, which has the advantages of fast juice extraction and solid-liquid separation of the centrifugal design, and solves the problem that ordinary juicers cannot add large-sized fruits to juice.

[0006] The utility model provides the following technical solution: a centrifugal fruit juicer, comprising a frame and a conical juicing barrel, the conical juicing barrel being detachably mounted on the lower end of the frame, a brushless DC motor being arranged inside the upper end of the frame, an output shaft being arranged at the output end of the brushless DC motor, the outer side of the output shaft being fixedly sleeved with evenly distributed connecting plates near the lower end, a detachable separation barrel being slidably mounted on the inner wall of the lower end of the conical juicing barrel, the inner wall of the separation barrel being fixedly connected with evenly distributed clips near the upper side, the clips being adapted to the connecting plates, a juice collecting barrel being mounted on the lower end of the conical juicing barrel, and splints being rotatably mounted on the left and right ends of the frame near the middle, the splints being resting against the lower end of the inclined surface of the conical juicing barrel.

[0007] Furthermore, the output shaft extends through the frame to the middle of the interior of the conical juicing barrel, and the outer side of the output shaft is fixedly sleeved with three groups of upper blade discs arranged in a circular array at the lower side near the conical juicing barrel, and the outer side of the output shaft is fixedly sleeved with three groups of lower blade discs arranged in a circular array at the lower side of the upper blade disc, and the ends of the lower blade disc and the upper blade disc away from the output shaft are close to the inner wall of the conical juicing barrel, and the lower blade disc and the upper blade disc are staggered, which ensures that the fruit is fully crushed and the juice yield is improved.

[0008] Furthermore, J-shaped slots are provided on both ends of the conical juicing barrel near the lower end, and the left and right inner walls of the juice collecting barrel are fixedly connected with blocks near the upper side, and the blocks are adapted to the J-shaped slots. The juice collecting barrel is connected to the conical juicing barrel through the engagement of the blocks with the J-shaped slots, which is used for the installation and fixation of the juice collecting barrel, which is not only simple and convenient, but also avoids splashing of juice.

[0009] Furthermore, the lower end of the splint is fixedly connected to a fixing cylinder near the front side, and the upper end of the base of the frame is fixedly connected to positioning rods on both sides near the front end. The upper end of the positioning rod is located inside the lower end of the fixing cylinder, and the adjacent ends of the fixing cylinders are provided with through grooves near the lower ends. The positioning rods and the through grooves are adapted to clamp and fix the conical juice barrel without manual support.

[0010] Furthermore, the outer side of the fixed cylinder is rotatably sleeved with a limit plate on the upper side of the positioning rod, and the limit pin rods are passed through the intersections between the limit plates. That is, through this limiting relationship, the conical juice barrel can be fixed while being easy to operate.

[0011] Furthermore, a feeding port is provided at the front end of the conical juicing barrel near the upper side, and a cover is provided at the upper end of the feeding port. The rear end of the cover is rotatably installed between the conical juicing barrel for adding materials, and the cover is used to prevent the juice and pomace inside from splashing out. It is worth mentioning that the conical juicing barrel and other structures of the device are made of transparent materials that can be seen through, and are non-toxic and harmless.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This juicer adopts a centrifugal design. The output shaft drives the upper and lower blade discs and the separation barrel to rotate, achieving rapid cutting and crushing of fruits and effective separation of juice and pomace. Under the action of centrifugal force, the juice quickly passes through the filter and enters the juice collection barrel to be collected, while the pomace is retained in the separation barrel, thereby greatly improving the taste and quality of the juice. In addition, the juicer also allows users to continuously add fruits during the juicing process without having to wait for the current batch to be squeezed before adding. This continuous juicing function greatly improves the efficiency and flexibility of juicing and meets the diverse needs of users.

[0014] 2. The juicer designed by the utility model realizes convenient disassembly and assembly functions in structure. Through simple operation, users can easily disassemble and install components such as the separation barrel, conical juice barrel and juice collection barrel without complicated tools or steps. This design not only facilitates the user's daily use, but more importantly, makes the cleaning of the juicer simple and quick. After juicing, users can quickly separate the various components and clean them thoroughly, effectively avoiding juice residue and bacterial growth, and ensuring the hygiene of the juicer and the health of the user.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 3 A centrifugal fruit juicer comprises a frame 1 and a conical juice extracting barrel 2. The conical juice extracting barrel 2 is detachably mounted on the lower end of the frame 1. A brushless DC motor is provided inside the upper end of the frame 1. The output end of the brushless DC motor is provided with an output shaft 3. The outer side of the output shaft 3 is fixedly sleeved with a uniformly distributed connecting plate 6 near the lower end. A detachable separation barrel 7 is slidably mounted on the inner wall of the lower end of the conical juice extracting barrel 2. The inner wall of the separation barrel 7 is fixedly connected with a uniformly distributed clamp 8 near the upper side. The clamp 8 is adapted to the connecting plate 6. The lower end of the conical juice extracting barrel 2 is fixedly sleeved with a uniformly distributed connecting plate 6. A juice collecting barrel 9 is installed at the end, and a clamping plate 12 is rotatably installed at both ends of the frame 1 near the middle. The clamping plate 12 is against the lower end of the inclined surface of the conical juice extracting barrel 2. When in use, the clamping piece 8 on the separation barrel 7 is staggered with the connecting plate 6 and then extended into the interior of the conical juice extracting barrel 2. Then, after rotating a certain angle, the lower end of the clamping piece 8 can be aligned with the connecting plate 6. Then, the separation barrel 7 can be loosened to engage the connecting plate 6 with the clamping piece 8 under the action of gravity, so that the output shaft 3 can be driven to rotate together. When squeezing juice, the juice is extracted through the feeding port 1. 8 can throw fruits of various sizes into the interior of the conical juice extraction barrel 2. After entering the interior of the conical juice extraction barrel 2, the fruits will always fall downward due to the action of gravity. After turning on the switch of the juicer, the output shaft 3 can be rotated to drive the upper blade disc 4 and the lower blade disc 5 to rotate, thereby quickly cutting and crushing the input fruits to release the juice. Similarly, the juice and crushed fruit pieces will fall into the interior of the separation barrel 7, and the separation barrel 7 will be driven by the output shaft 3 to rotate together due to the clamping effect of the connecting plate 6 and the clamping member 8, so that the pomace and juice in the separation barrel 7 are separated. Under the action of centrifugal force, the juice is quickly separated, that is, the juice will eventually enter the juice collecting barrel 9 and be collected, while the pomace will still remain in the separation barrel 7. Compared with some current fruit juicers, this device does not require the user to press the juice barrel with his hands to keep it stable and sealed when juicing. At the same time, by flipping open the cover 19, the fruit can be continuously put in for juicing, and there is no need to put the fruit into the juice barrel first. It is more flexible and convenient to use. The design of the separation barrel 7 not only improves the efficiency of juicing, but also improves the taste of the juice, greatly improving the user experience.

[0022] See also Figure 2The outer side of the output shaft 3 is fixedly sleeved with three groups of upper blade discs 4 arranged in a circular array near the lower side of the conical juice extracting barrel 2. The outer side of the output shaft 3 is fixedly sleeved with three groups of lower blade discs 5 arranged in a circular array at the lower side of the upper blade disc 4. The lower blade disc 5 and the upper blade disc 4 away from the output shaft 3 are close to the inner wall of the conical juice extracting barrel 2. The lower blade disc 5 and the upper blade disc 4 are staggered. After turning on the switch of the juice extractor, the brushless DC motor arranged inside the upper end can be operated and drive the output shaft 3 to rotate, thereby driving the upper blade disc 4 and the lower blade disc 5 to rotate through the rotation of the output shaft 3. That is, through the staggered arrangement and the design close to the inner wall of the conical juice extracting barrel 2, the input fruit can be crushed quickly and efficiently, while preventing the larger-sized fruit pulp that has not been thoroughly crushed from falling into the interior of the separation barrel 7.

[0023] See also Figure 3-Figure 4 The left and right ends of the conical juicing barrel 2 are both provided with J-shaped slots 11 near the lower end, and the left and right inner walls of the juice collecting barrel 9 are fixedly connected with a clamping block 10 near the upper side. The clamping block 10 is adapted to the J-shaped slot 11, and the juice collecting barrel 9 is connected to the conical juicing barrel 2 through the clamping block 10 and the J-shaped slot 11. After aligning the clamping block 10 on the juice collecting barrel 9 with the J-shaped slot 11, push it upward and then rotate it a certain angle, and then release the juice collecting barrel 9 to complete the connection and fixation between it and the conical juicing barrel 2. The above operation and disassembly are similar. The operation is simple and quick, convenient for users to use, and convenient for cleaning the interior.

[0024] See also Figure 1-Figure 2 The lower end of the splint 12 is fixedly connected to a fixed cylinder 13 near the front side, and the upper end of the base of the frame 1 is fixedly connected to a positioning rod 14 on both sides near the front end. The upper end of the positioning rod 14 is located inside the lower end of the fixed cylinder 13, and the end close to the fixed cylinder 13 is provided with a through groove 15 near the lower end. The positioning rod 14 is adapted to the through groove 15. The outer side of the fixed cylinder 13 is rotatably sleeved on the upper side of the positioning rod 14. The limiting pin rod 17 is passed through the intersection between the limiting plates 16. The front end of the conical juice extracting barrel 2 is provided with a feeding port 18 near the upper side. The feeding port 18 is A cover plate 19 is provided at the upper end, and the rear end of the cover plate 19 is rotatably installed between the conical juicing barrel 2. By putting the conical juicing barrel 2 on the lower end of the frame 1, the rotating splint 12 is pressed against the conical juicing barrel 2. During this process, the positioning rod 14 will be stuck into the interior of the fixed cylinder 13 through the through groove 15, thereby providing support to the fixed cylinder 13 and the splint 12 through the positioning rod 14, and at the same time playing a limiting role, that is, after rotating the limiting plate 16 to be parallel, the limiting pin rod 17 is inserted into the intersection between the limiting plates 16 in sequence, thereby completing the limiting fixation of the splint 12, and then realizing the fixation of the conical juicing barrel 2.
