Description

Technical Field

[0001] This utility model relates to the technical field of juicing equipment, and more particularly to a juicer. Background Technology

[0002] Juicers, capable of processing fruits and vegetables into delicious beverages, have always been popular. With the improvement of living standards, juicers have moved from beverage shops into the kitchens of countless households, becoming an essential helper for enhancing people's quality of life.

[0003] Juicers typically require users to assemble them before use and disassemble them afterward for easy cleaning. Each time a juicer is cleaned, the juicing parts need to be disassembled and thoroughly cleaned to prevent juice residue from causing mold growth and contaminating the juicer, affecting its next use. However, disassembling multiple parts increases the number of steps required for cleaning, making it inconvenient to use. Therefore, how to make juicers easier to clean has always been a problem that researchers in the industry have been considering. Utility Model Content

[0004] The purpose of this invention is to provide a juicer that solves the technical problem of easy cleaning of juicers.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a juicer is provided, comprising: a base, a pressing cup, and a pressing barrel. The pressing cup is installed on the base, the pressing barrel is installed on the pressing cup, a pressing component is provided inside the pressing cup, a power mechanism is provided inside the base, the power mechanism drives the pressing component to rotate, and a fixing device is provided on the upper part of the pressing component, the fixing device fixing the pressing component to the lower part of the pressing barrel.

[0006] This juicer utilizes a fixing device to secure the pressing component to the lower part of the pressing barrel. During disassembly and cleaning, the pressing barrel removes the pressing component along with the juicer, allowing for simultaneous rinsing. Simultaneously, the elimination of the pressing component reduces the number of cleaning components inside the pressing cup from three to two, simplifying the cleaning process and facilitating the use of brushes and other cleaning tools, significantly improving the juicer's cleaning efficiency. Finally, because the pressing component is fixed to the lower part of the pressing barrel, components above it, such as the pre-cutting blade (if present), do not need to be disassembled from the pressing barrel for cleaning. Therefore, the diameter of the pre-cutting blade can be larger than the bottom diameter of the pressing barrel, increasing the pre-cutting diameter and enabling the direct pre-cutting of materials exceeding the radius of the pressing barrel.

[0007] Preferably, a pressing shaft is provided on the top of the pressing component, and the fixing device fixes the pressing shaft to the lower part of the pressing barrel. The pressing shaft transmits the power provided by the power mechanism to the pressing component, and the pressing shaft and the power mechanism are connected by a shaft. The pressing component is driven by the pressing shaft, which makes power transmission simple and fast, and the pressing shaft part is also easy to clean.

[0008] More preferably, a pre-cutting blade is provided inside the pressing barrel, and a fixing device is provided on the top of the pre-cutting blade. This fixing device secures the pressing shaft, the pre-cutting blade, and the pressing components together to the pressing barrel. This fixing device facilitates the assembly of the pre-cutting blade and the pressing components, and also facilitates the cleaning of the pressing components.

[0009] Preferably, the pressing component has a fixing rib extending outward from its top, and the fixing device is a slot located around the bottom of the pressing barrel for fixing the fixing rib to the bottom of the pressing barrel. This peripheral fixing device helps stabilize the pressing component during rotation, ensuring uniformity and efficiency of juicing.

[0010] More preferably, the fixing ribs are at least two that are broken circumferentially. The discontinuous fixing ribs reduce the contact area between the fixing ribs and the fixing device, i.e., the slot, which helps to reduce the friction between the pressing parts and the fixing device, reduce power loss, and improve pressing efficiency.

[0011] More preferably, the aforementioned fixing ribs are evenly distributed circumferentially. This even distribution of fixing ribs helps to balance the forces on the pressing component, preventing it from shaking or shifting during rotation and cleaning, thus affecting its service life.

[0012] More preferably, the portion of the fixing rib that contacts the fixing device is at least partially made of wear-resistant material. Since the fixing rib and the fixing device move relative to each other over a long period, making the contact portion of the fixing rib wear-resistant material helps to extend the service life of the pressing parts and the pressing barrel, while also reducing the coefficient of friction.

[0013] More preferably, the portion of the fixing rib that contacts the fixing device is at least partially made of metal. This design reduces the coefficient of friction between the fixing rib and the fixing device, while increasing the service life of the pressing components and the pressing barrel.

[0014] More preferably, the contact area between the fixing rib and the fixing device is greater than or equal to 5 square millimeters. If the contact area is less than 5 square millimeters, the coefficient of friction between the two will be greatly increased, and the fixing rib will be prone to breakage due to its small size and thinness.

[0015] More preferably, the wall thickness of the aforementioned fixing device is greater than or equal to 2mm. Since the fixing device is subject to wear over a long period of time, when the wall thickness is less than 2mm, the fixing device of the pressing barrel is easily worn through, reducing its service life; at the same time, this wall thickness also improves the strength at this location, preventing breakage during disassembly due to the slot being too thin.

[0016] More preferably, the axial clearance between the fixing device and the fixing rib is 0.2mm to 10mm. When the axial clearance is less than 0.2mm, the slot and the fixing rib are too tight, which will greatly increase the friction between them and increase the power loss of the pressing component. When the axial clearance is greater than 10mm, the pressing component will easily shake, resulting in uneven juicing and increased wear on the drive shaft.

[0017] More preferably, the fixing device and the fixing rib exhibit rolling friction. The installation of rollers or balls between the fixing device and the fixing rib effectively reduces friction and power loss.

[0018] More preferably, a planar bearing is provided between the fixing device and the fixing rib. The installation of the planar bearing greatly reduces the friction between the fixing device and the fixing rib, thereby reducing power loss.

[0019] Preferably, the pressing component is a first pressing mesh, the inner wall of which is provided with pressing ribs. The first pressing mesh performs pressing from the inside, forcing the juice through the mesh to the outside. The pressing ribs effectively improve the pressing efficiency of the first pressing mesh and increase its structural strength.

[0020] More preferably, a pressing rod is provided inside the first pressing mesh, and the pressing rod is fixed to the base. The pressing rod can work with the first pressing mesh to control the pressing gap, effectively improving the pressing efficiency.

[0021] More preferably, the press rod is provided with ribs. The ribs can effectively improve the pressing efficiency of the press element and the press rod.

[0022] More preferably, the top of the first pressing screen is provided with a first discharge hole. This first discharge hole can easily allow the material to fall into the interior of the first pressing screen, facilitating pressing.

[0023] Preferably, the pressing component is a screw, and a second pressing screen is provided on the outside of the screw, which is fixed inside the pressing cup. The pressing component, the screw, presses the material from the outside, and in conjunction with the second pressing screen, squeezes out the juice from the material.

[0024] More preferably, a second discharge hole is provided around the upper part of the screw. This second discharge hole can conveniently allow material to fall between the screw and the second pressing screen. Attached Figure Description

[0054] Example 1:

[0055] like Figure 1 , Figure 2 As shown, Figure 1 This is a cross-sectional view of the juicer 1000 according to Embodiment 1 of this utility model. Figure 2 This is a cross-sectional view of the pressing barrel 1300 and the first pressing screen 1210 of the juicer 1000 according to Embodiment 1 of this utility model.

[0056] This embodiment discloses a juicer 1000, including a pressing barrel 1300, a pressing cup 1200, and a base 1100. The pressing cup 1200 is mounted on the base 1100, and the pressing barrel 1300 is mounted on the pressing cup 1200.

[0057] A pressing element, namely a first pressing screen 1210, is installed inside the pressing cup 1200. A power mechanism 1110 is installed inside the base 1100, which drives the first pressing screen 1210 to rotate. A pressing shaft 1212 is installed on the first pressing screen 1210, and the pressing shaft 1212 is connected to a shaft extending from the power mechanism 1110. A pressing rod 1120 is installed above the base 1100, and the pressing rod 1120 cooperates with the first pressing screen 1210 to perform pressing. The pressing rod 1120 is fixed to the base 1100 and will not rotate. The pressing rod 1120 is provided with longitudinal ribs (not shown). The first pressing screen is fixed at the lower part of the pressing shaft 1212, passes through the bottom of the pressing barrel 1300 in the middle, and a pre-cutting blade 1310 is installed at the upper part. The pre-cutting blade 1310 is disposed inside the pressing barrel 1300. The pre-cutting blade 1310 is fixed to the pressing shaft 1212 by a fixing device 1211 above it. At the same time, the fixing device 1211 fixes the pressing shaft 1212 and the first pressing screen 1210 to the pressing barrel 1300.

[0058] The first pressing screen 1210 has a first discharge hole 1215 at its top, which is used to discharge material from the pressing barrel 1300 into the space between the first pressing screen 1210 and the pressing rod 1120. The first pressing screen 1210 has fixing feet 1213 around its top perimeter, which are supported on the inner wall of the pressing barrel 1300 or the pressing cup 1200 to stabilize the rotation of the first pressing screen 1210.

[0059] The inner wall of the pressing barrel 1300 is also equipped with a pre-cutting baffle 1320, which is used to work with the pre-cutting blade 1310 to shear the material and improve the pressing efficiency.

[0060] In this embodiment, the juicer 1000 uses a fixing device 1211 to fix the first pressing screen 1210 to the bottom of the pressing barrel 1300. When the pressing barrel 1300 is disassembled for cleaning, the first pressing screen 1210 will be removed together, which facilitates the cleaning of the first pressing screen 1210 and the inside of the pressing cup 1200, thus improving the cleaning and disassembly efficiency of the juicer 1000.

[0061] Example 2:

[0062] like Figure 3 The diagram shown is a partial structural schematic of the juicer according to Embodiment 2 of this utility model.

[0063] This embodiment discloses a juicer (not shown), which has a structure that is basically the same as the juicer 1000 in Embodiment 1 of this utility model, except that the differences are as follows.

[0064] The juicer (not shown) of this embodiment includes a pressing barrel 2300 and a pressing cup 2200. The pressing barrel 2300 is mounted on the pressing cup 2200. A pressing component, namely a screw 2210, is provided inside the pressing cup 2200. A second pressing screen 2220 is provided outside the screw 2210 and is disposed on the inner wall of the pressing cup 2200. The upper part of the screw 2210 is fixed to the lower part of the pressing barrel 2300 by a pressing shaft 2212, and the power provided by the power mechanism (not shown) is transmitted to the screw 2210 through the pressing shaft 2212 to make the screw 2210 rotate. A pre-cutting blade 2310 is provided inside the pressing barrel 2300, and the pre-cutting blade 2310 is fixed inside the pressing shaft 2212 by a fixing device 2211. Meanwhile, the fixing device 2211 fixes the pressing shaft 2212 and the screw 2210 together below the pressing barrel 2300.

[0065] The juicer of this embodiment (not shown) has essentially the same effect as the juicer 1000 of Embodiment 1. In addition, the screw 2210 of this embodiment is capable of pressing harder materials.

[0066] Example 3:

[0067] like Figure 4 The diagram shown is a partial structural schematic of the juicer (not shown) according to Embodiment 3 of this utility model.

[0068] This embodiment discloses a juicer (not shown), which has a structure that is basically the same as the juicer 1000 in Embodiment 1 of this utility model, except that the differences include the following:

[0069] The juicer (not shown) of this embodiment includes a pressing barrel 3300 and a pressing cup (not shown). A first pressing screen 3210 is provided inside the pressing cup (not shown). A fixing rib 3213 extends outward from the upper part of the first pressing screen 3210. The fixing rib 3213 is continuous in the circumferential direction. A fixing member 3216 is provided below the pressing barrel 3300. The fixing member 3216 cooperates with the bottom of the pressing barrel 3300 to form a fixing device, namely a groove 3211. The groove 3211 is annular and fixes the fixing rib 3213 to the bottom of the pressing barrel 3300. A plane bearing 3217 is provided inside the groove 3211 to greatly reduce the friction between the fixing rib 3213 and the groove 3211. The wall thickness of the groove 3211 is 2mm. The longitudinal gap between the groove 3211 and the fixing rib 3213 is 10mm.

[0070] The first pressing screen 3210 is equipped with a pre-cutting blade 3310 on its upper part, and a gate-shaped pre-cutting stop 3320 is provided below the pressing barrel 3300, so that the pre-cutting blade 3310 can extend into the pressing barrel 3300 and cooperate with the pre-cutting blade 3310 to shear the material.

[0071] The juicer of this embodiment (not shown) has essentially the same effect as the juicer 1000 of Embodiment 1. In addition, the first pressing screen 3210 is more stable because it is fixed in a peripheral manner.

[0072] Example 4:

[0073] like Figure 5 The diagram shown is a partial structural schematic of the juicer (not shown) according to Embodiment 4 of this utility model.

[0074] This embodiment discloses a juicer (not shown), which has a structure that is basically the same as the juicer in Embodiment 3 of this utility model, except that the differences include the following.

[0075] The juicer (not shown) of this embodiment includes a pressing barrel 4300 and a pressing cup (not shown). A screw 4210 is provided inside the pressing cup (not shown). Three fixing ribs 4213 extend outward from the upper part of the screw. In other embodiments, the number of fixing ribs may be two or more. The three fixing ribs 4213 are evenly distributed circumferentially. A fixing member 4216 is provided below the pressing barrel 4300. The fixing member 4216 cooperates with the bottom of the pressing barrel 4300 to form a fixing device, namely a groove 4211. The groove 4211 is annular and fixes the fixing ribs 4213 to the bottom of the pressing barrel 4300. The part of the groove 4211 that contacts the fixing ribs 4213 is provided with a wear-resistant metal material. The wall thickness of the groove 4211 is 3mm. The axial gap between the groove 4211 and the fixing ribs 4213 is 0.2mm. In other embodiments, this gap may also be 1mm.

[0076] The juicer in this embodiment (not shown) has essentially the same effect as the juicer in Embodiment 3.

[0077] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
