Description

Technical Field

[0001] This utility model relates to the field of juicer technology, and in particular to a slow juicer. Background Technology

[0002] Currently, the most common juicers on the market are mainly divided into centrifugal juicers and screw extruder juicers (also known as slow juicers). Centrifugal juicers use high-speed rotating blades to break down the ingredients, and then use centrifugal force to throw the pulp and fiber against the inner wall of a filter to extract the juice. The juice then flows through the holes in the filter into the juice chamber. However, under the action of centrifugal force, the juice will generate violent friction with oxygen in the air, causing the nutrients in the juice to oxidize and affecting the taste of the juice.

[0003] The core component of a juicer is a spiral-shaped pressing screw. When ingredients are fed into the juicer, the screw slowly rotates, gradually squeezing the ingredients to extract the juice. This squeezing process is relatively gentle and better preserves the nutrients in the ingredients, making it more popular with consumers.

[0004] Currently, most juicers on the market use a "screw rotates while the filter remains stationary" method for juicing. However, during the screw rotation, fruits and vegetables are pushed along with the screw. Due to the spiral shape and rotational motion of the screw, the distribution of fruits and vegetables between the screw and the filter is often uneven, resulting in insufficient juicing and affecting the juicing effect and juice yield.

[0030] This utility model provides a juicer 100, which aims to solve the problem of insufficient juicing caused by uneven distribution of fruits and vegetables during the juicing process in traditional juicers, thus affecting the juicing effect and juice yield.

[0031] like Figures 1 to 5 As shown, the juicer 100 provided by this utility model includes a body 70, a filter screen 10, a juicing assembly 20, and a drive mechanism 30. The body 70 includes a feeding chamber 40 and a juice chamber 50 disposed below the feeding chamber 40. A feeding port 43 is provided at the bottom of the feeding chamber 40, and a receiving port 51 is provided at the top of the juice chamber 50 opposite to the feeding port 43. The filter screen 10 is disposed inside the juice chamber 50 and located below the receiving port 51. The juicing assembly 20 includes a juicing head 21, which is at least partially disposed within the juice chamber 50. The juicing head 21 can be completely located inside the filter screen 10, or partially located inside and partially located outside the filter screen 10. The drive mechanism 30 includes a rotating shaft 31 and a transmission structure 33. The rotating shaft 31 is located at the axis of the juicing head 21 and connected to the juicing head 21. The transmission structure 33 is located at the bottom of the feed hopper 40 and is connected to the rotating shaft 31 and the filter screen 10 for transmitting the rotation of the rotating shaft 31 to the filter screen 10 so that the filter screen 10 and the juicing head 21 rotate relative to each other.

[0032] In this juicer 100, the body 70 includes a feeding chamber 40 and a juice chamber 50 located below the feeding chamber 40. The bottom of the feeding chamber 40 has a feeding port 43. Figure 3As shown, the top of the juice container 50 has a receiving port 51 positioned opposite the feeding port 43. For example, the top of the juice container can be fully open to form the receiving port 51, such as... Figure 1 As shown, or, the top of the juice chamber is equipped with a cover plate, and a receiving port 51 is opened on the cover plate. The filter screen 10 is set inside the juice chamber 50 and below the receiving port 51, so as to ensure that the fruits and vegetables falling from the receiving port 51 can fall into the filter screen 10. The filter screen 10, the juice chamber 50 and the feeding chamber 40 can be arranged coaxially. The top of the feeding chamber 40 is provided with a feeding port (not shown), and the feeding port is covered with a top cover. The top cover is configured to open and close the feeding port. For example, the top cover is a flip-top design, so that the feeding port can be opened and closed by flipping the top cover; or, the top cover is a press-top design, so that the feeding port can be opened and closed by removing and placing the top cover, so that the user can easily open the top cover and put the fruits and vegetables into the feeding chamber 40. Subsequently, the fruits and vegetables in the feeding chamber 40 will fall into the filter screen 10 through the feeding port 43 and the receiving port 51.

[0033] In this technical solution, the juicing head 21 can be a spiral juicing head. Traditional juicers typically use a "juicing head rotates while the filter screen remains stationary" method. However, during the screw's rotation, fruits and vegetables are propelled along with it. Due to the spiral shape and rotational motion of the screw, the distribution of fruits and vegetables between the screw and the filter screen 10 is often uneven, resulting in insufficient juicing and affecting the juicing effect and yield. Unlike traditional juicers, the juicer 100 of this invention connects the drive mechanism 30 to the filter screen 10 via a transmission connection. The drive mechanism 30 drives the filter screen 10 to rotate relative to the juicing head 21 for compression juicing.

[0034] Specifically, refer to Figure 2 The drive mechanism 30 includes a rotating shaft 31 and a drive component 32 for driving the rotating shaft 31 to rotate. The drive component 32 can be a stepper motor or a DC motor. The rotating shaft 31 is located at the axis of the juicing head 21 and connected to the juicing head 21, thereby driving the juicing head 21 to rotate. The drive mechanism 30 also includes a transmission structure 33, which is located at the bottom of the feeding chamber 40 and is connected to the rotating shaft 31 and the filter screen 10 for transmitting the rotation of the rotating shaft 31 to the filter screen 10, so that the filter screen 10 rotates relative to the juicing head 21. The rotation of the filter screen 10 continuously changes the contact position between the fruits and vegetables and the inner wall of the filter screen 10, thereby dispersing the accumulated fruits and vegetables and distributing them evenly within the filter screen 10, thus ensuring that the fruits and vegetables are evenly squeezed during the juicing process, improving the juicing effect and juice yield.

[0035] When the juicing head 21 and the filter screen 10 rotate simultaneously, the fruits and vegetables are squeezed from both directions within the filter screen 10, which more effectively extracts the juice, thereby improving juicing efficiency and yield. At the same time, the relative rotation between the filter screen 10 and the juicing head 21 causes the fruits and vegetables to continuously tumble and move within the filter screen 10, further promoting a uniform distribution of the fruits and vegetables within the filter screen 10.

[0036] It's easy to understand that if the juicing head 21 and the filter 10 rotate in the same direction and at the same speed, the fruits and vegetables will not be subjected to effective shearing force between the filter 10 and the juicing head 21. Therefore, in this technical solution, when the filter 10 and the juicing head 21 rotate in the same direction, there must be a difference between the speed of the filter 10 and the speed of the juicing head 21; that is, the speed of the filter 10 must be greater than or less than the speed of the juicing head 21. Alternatively, the rotation direction of the filter 10 can be opposite to that of the juicing head 21. For example, if the filter 10 rotates clockwise, the juicing head 21 rotates counterclockwise, or vice versa. In this case, the speed of the filter 10 and the speed of the juicing head 21 can be equal or unequal.

[0037] It is worth mentioning that in traditional juicers, the rotation speed of the juicing head is usually low, resulting in low juicing efficiency and long juicing time. In this technical solution, when the rotation direction of the filter 10 is opposite to that of the juicing head 21, the relative speed between them increases significantly. This higher relative speed can more effectively squeeze fruits and vegetables, making the juicing process faster, thereby significantly improving juicing efficiency and shortening juicing time.

[0038] In one embodiment, the filter 10 includes an integrally connected filter body 11 and a toothed ring 12 disposed at the end of the filter body 11, the inner peripheral wall of the toothed ring 12 being provided with gear teeth. (Refer to...) Figure 5 The transmission structure 33 includes a drive gear 331, which is connected to the rotating shaft 31 and rotates under the drive of the rotating shaft 31. The drive gear 331 meshes directly or indirectly with the gear ring 12, thereby transmitting the rotation of the rotating shaft 31 to the filter screen 10.

[0039] Direct meshing means that the driving gear 331 can directly mesh with the gear ring 12 as an internal gear. In this case, the number of teeth of the driving gear 331 is greater than or less than the number of teeth of the gear ring 12, thereby ensuring that there is a difference between the rotational speed of the filter screen 10 and the rotational speed of the juicing head 21. The direct meshing of the driving gear 331 and the gear ring 12 can ensure the high efficiency of power transmission and reduce energy loss.

[0040] Indirect meshing means that a driven gear 332 can be provided between the driving gear 331 and the gear ring 12, with both the driving gear 331 and the gear ring 12 meshing with the driven gear 332. Figure 5In the illustrated embodiment, the driven gear 332 externally meshes with the driving gear 331 and internally meshes with the gear ring 12. At this time, the driven gear 332 rotates under the drive of the driving gear 331, thereby driving the gear ring 12 to rotate, and thus driving the filter screen 10 to rotate. The driving gear 331 and the gear ring 12, through the meshing of the driven gear 332, form a multi-stage transmission structure. Different speed ratios can be achieved by increasing the number of driven gears 332 or adjusting the number of teeth on the driven gears 332. Furthermore, by changing the meshing method of the driving gear 331 and the driven gear 332, the forward and reverse rotation of the filter screen 10 can be easily adjusted, providing more juicing modes for the juicer 100. Gear transmission is a mature mechanical transmission method with high reliability and durability.

[0041] Please continue to refer to Figure 5 In some embodiments of this invention, the transmission structure 33 further includes a planetary carrier 333, on which the driven gear 332 is rotatably mounted. The planetary carrier 333 provides support for the driven gear 332, ensuring that the driven gear 332 can rotate in the correct position. The planetary carrier 333 can be fixedly mounted at the bottom of the feed hopper 40, meaning it does not rotate with the shaft 31; in this case, the driven gear 332 only rotates around its own axis. Alternatively, the planetary carrier 333 can be rotatably mounted at the bottom of the feed hopper 40, in which case the driven gear 332 can not only rotate around its own axis but also revolve around the shaft 31. This configuration provides greater flexibility to the transmission system, allowing for dynamic adjustment of the speed and direction of the filter 10 to adapt to different juicing needs.

[0042] In summary, the transmission structure 33 in this embodiment adopts a planetary gear transmission structure. Planetary gear transmission is a highly efficient mechanical transmission structure that ensures high efficiency in power transmission. Furthermore, the planetary gear transmission structure provides the juicer 100 with greater flexibility and efficiency, enabling it to better meet the juicing needs of different fruits and vegetables. In the embodiment shown in the figure, three driven gears 332 are provided. Of course, in actual applications, the number of driven gears 332 can be flexibly adjusted. The more driven gears 332 there are, the more the force on each individual gear can be distributed, thereby reducing the risk of gear wear and damage, and improving the stability and reliability of the entire transmission structure 33.

[0043] Reference Figure 2In this juicer 100, the juicing assembly 20 also includes a blade 22, which is connected to the rotating shaft 31 so that the rotating shaft 31 can drive the blade 22 to rotate together. Specifically, the blade 22 is located at the bottom of the feeding chamber 40 and is connected to the rotating shaft 31. The rotation of the rotating shaft 31 will drive the juicing head 21, the filter screen 10, and the blade 22 to rotate together. The function of the blade 22 is to perform preliminary cutting on the fruits and vegetables entering the feeding chamber 40. During the rotation, the blade 22 cuts large pieces of fruits and vegetables into smaller pieces, ensuring that the fruits and vegetables can pass smoothly through the feeding port 43 and the receiving port 51 and fall into the gap between the filter screen 10 and the juicing head 21. The blade 22 can be designed in a blade shape. The blade-shaped blade 22 is sharp and can cut fruits and vegetables well. Its material can be, but is not limited to, stainless steel, ceramic, and titanium alloy. These materials have high strength, good corrosion resistance and wear resistance, and are not easy to rust, which can ensure the service life of the blade 22.

[0044] It should be noted that the juice chamber 50 is equipped with a handle for easy gripping and an outlet for easy juice flow, making it convenient for users to pour juice into cups or other containers. In this technical solution, the feeding chamber 40 and the juice chamber 50 can be detachably connected, such as by threaded connection or snap-fit ​​connection, so that the feeding chamber 40 and the juice chamber 50 can be separated from each other. After juicing is complete, the user can easily remove the feeding chamber 40, allowing the juice chamber 50 to be used independently. This avoids making the entire juicer 100 too heavy and reduces the burden on the user when pouring juice.

[0045] Reference Figure 4 The feeding hopper 40 includes a chassis 41 and a surrounding barrel 42 protruding from the chassis 41. The chassis 41 has a feeding port 43. The drive gear 331 includes a wheel 3311 and a central shaft 3312 protruding from the center of the wheel 3311. The central shaft 3312 is rotatably inserted through the chassis 41. The cutter 22 is located at the bottom of the feeding hopper 40 and is fixedly connected to the central shaft 3312. The central shaft 3312 is connected to the juicing head 21 for transmission, thereby realizing the transmission between the cutter 22, the drive gear 331 and the juicing head 21.

[0046] Regarding the connection between the drive gear 331 and the juicing head 21, please refer to... Figure 2 and Figure 4The top of the juicing head 21 has a protruding adapter shaft 211, which is located on the axis of the juicing head 21. The end of the central shaft 3312 facing the juice chamber 50 has an adapter interface 3313 for inserting the adapter shaft 211. When the feed chamber 40 is placed on top of the juice chamber 50, the adapter shaft 211 is inserted into the adapter interface 3313, thus achieving a transmission connection between the rotating shaft 31, the drive gear 331, and the cutter 22. Therefore, the rotation of the rotating shaft 31 will drive the juicing head 21 to rotate, which in turn will drive the drive gear 331 to rotate, which will in turn drive the cutter 22 to rotate, and simultaneously drive the driven gear 332 and the filter screen 10 to rotate.

[0047] Continue to refer to Figure 4 In one embodiment of this utility model, the chassis 41 includes a first chassis 411 and a second chassis 412 spaced above the first chassis 411. A mounting interlayer is formed between the first chassis 411 and the second chassis 412. The central shaft 3312 of the driving gear 331 rotatably passes through the first chassis 411 and the second chassis 412. The wheel 3311 is disposed within the mounting interlayer. The cutter 22 is disposed on the second chassis 412 and fixedly connected to the central shaft 3312. Feed ports 43 are provided on the first chassis 411 and the second chassis 412, respectively, and are disposed opposite to each other. The driven gear 332 is rotatably mounted on the second chassis 412 and located within the mounting interlayer. In this case, the second chassis 412 is equivalent to the planetary carrier 333 mentioned above.

[0048] In this embodiment, the chassis 41 of the feeding hopper 40 is set as a double-layer chassis - a first chassis 411 and a second chassis 412, and an installation interlayer is formed between the first chassis 411 and the second chassis 412. The transmission mechanism is then hidden in the installation interlayer, avoiding the exposure of the transmission mechanism, making the appearance of the feeding hopper 40 more concise and beautiful.

[0049] Reference Figure 1 and Figure 2 In some embodiments of the juicer 100, the body 70 further includes a base 60, which is disposed below the juice chamber 50. The drive component 32 is disposed within the base 60, and the rotating shaft 31 passes through the top wall of the base 60 to connect with the juicing head 21. The base 60 serves to provide stable support for the entire juicer 100, ensuring that the machine does not shake or tip over during juicing. Simultaneously, by housing the drive component 32 within the base 60, the drive component 32 avoids occupying space in the juice chamber 50, thereby maximizing the capacity of the juice chamber 50.

[0050] Similarly, the base 60 and the juice container 50 can be detachably connected, such as by a threaded connection or a snap-fit ​​connection, so that the juice container 50 and the base 60 can be separated from each other, making it convenient for users to remove the juice container 50 from the base 60 and clean it separately, removing any remaining fruit pulp and juice, and preventing odors and bacterial growth.

[0051] Reference Figure 6 In some embodiments of this utility model, the filter screen 10 includes a first filter screen 10a and a second filter screen 10b. The second filter screen 10b is sleeved on the first filter screen 10a and coaxially arranged with the first filter screen 10a. The juicing head 21 is disposed inside the first filter screen 10a. The driving mechanism 30 is at least connected to the first filter screen 10a for driving the first filter screen 10a to rotate relative to the juicing head 21 and the second filter screen 10b.

[0052] The drive mechanism 30 can be connected only to the first filter screen 10a. The drive mechanism 30 drives the first filter screen 10a to rotate relative to the juicing head 21 and the second filter screen 10b, while the second filter screen 10b remains stationary. At this time, the first filter screen 10a includes an integrally connected filter screen body 11 and a toothed ring 12 disposed at the end of the filter screen body 11. The drive gear 331 directly or indirectly meshes with the toothed ring 12 of the first filter screen 10a, thereby driving the first filter screen 10a to rotate relative to the juicing head 21 and the second filter screen 10b.

[0053] Alternatively, both the first filter screen 10a and the second filter screen 10b are connected to the drive mechanism 30, which drives the first filter screen 10a and the second filter screen 10b to rotate simultaneously. In this case, the ends of the first filter screen 10a and the second filter screen 10b are provided with toothed rings 12, which mesh directly or indirectly with the drive gear 331.

[0054] The first filter screen 10a and the second filter screen 10b can be made of stainless steel to ensure good corrosion resistance and wear resistance. In this embodiment, the filter screen 10 is set as a double-layer filter screen 10, which can realize dual filtration. That is, the first filter screen 10a is responsible for the initial filtration of the extracted juice, and the second filter screen 10b further filters the juice flowing out from the mesh of the first filter screen 10a, thereby improving the purity of the juice. At the same time, the rotational movement of the first filter screen 10a relative to the juicing head 21 and the second filter screen 10b can realize dual juicing. The shearing force generated by the relative rotation between the first filter screen 10a and the juicing head 21 can perform an initial squeeze on the fruits and vegetables. The initially extracted juice flows into the space between the first filter screen 10a and the second filter screen 10b through the mesh of the first filter screen 10a. Subsequently, the shearing force generated by the relative rotation between the first filter screen 10a and the second filter screen 10b will perform a second squeeze on the fruits and vegetables, so that the juice in the fruits and vegetables can be extracted more fully and the juicing efficiency can be improved.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
