Description

Technical Field

[0001] The present invention relates to the technical field of juicing equipment, and particularly relates to a juicer. Background Art

[0002] Juicers can process fruits, vegetables, etc. into delicious drinks and have always been popular among people. With the improvement of people's living standards, juicers have moved from beverage stores to the kitchens of thousands of households and have become essential helpers for people to enhance their quality of life.

[0003] Generally, users need to perform simple assembly before using a juicer and simple disassembly after use for easy cleaning and other operations. Each time the juicer is cleaned, the components in the juicing part need to be disassembled and then cleaned thoroughly to prevent juice residue from mildewing and contaminating the juicer, which affects the next use. However, the disassembly of multiple components increases the operation steps during cleaning by users, which is not conducive to use. Therefore, how to make the juicer easy to clean has always been a problem that R & D personnel in this industry have been thinking about. Summary of the Invention

[0004] The purpose of the present invention is to provide a juicer to solve the technical problem of easy cleaning of the juicer.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: to provide a juicer, including: 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 member is arranged inside the pressing cup, a power mechanism is arranged inside the base, the power mechanism drives the pressing member to rotate, a fixing device is arranged on the upper part of the pressing member, and the fixing device fixes the pressing member at the lower part of the pressing barrel.

[0006] In the juicer of the present invention, by setting a fixing device to fix the pressing member at the lower part of the pressing barrel, when disassembling and cleaning, the pressing barrel will remove the pressing member together and wash them together; at the same time, since there is one less pressing member inside the pressing cup, the number of cleaning parts changes from three to two, which simplifies the cleaning process and also facilitates the brushing action of cleaning objects such as brushes, greatly improving the cleaning efficiency of the juicer. Finally, since the pressing member is fixed at the lower part of the pressing barrel, the components above the pressing member, such as the pre-cutting knife, if any, do not need to be disassembled from the pressing barrel for cleaning. Therefore, the diameter of the pre-cutting knife can be larger than the bottom diameter of the pressing barrel, increasing the pre-cutting diameter and enabling direct pre-cutting of materials that exceed the radius of the pressing barrel.

[0007] Preferably, a pressing shaft is arranged at the top of the pressing member, and the fixing device fixes the pressing shaft at the lower part of the pressing barrel. The pressing shaft transmits the power provided by the power mechanism to the pressing member, and the pressing shaft is docked with the power mechanism by a shaft. Driving the pressing member through the pressing shaft, the power transmission is simple and fast, and the part of the pressing shaft is also convenient for cleaning.

[0008] More preferably, a pre-cutting knife is provided inside the above-mentioned pressing barrel, and a fixing device is arranged at the top of the pre-cutting knife. The fixing device fixes the pressing shaft, the pre-cutting knife and the pressing member together on the pressing barrel. Through the arrangement of the fixing device, the pre-cutting knife and the pressing member can be conveniently assembled, and at the same time, the cleaning of the pressing member is facilitated.

[0009] Preferably, fixing ribs extend outward from the top of the above-mentioned pressing member to the periphery, and the above-mentioned fixing device is a clamping groove, which is located around the bottom of the pressing barrel and is used to fix the fixing ribs to the bottom of the pressing barrel. The fixing device around the periphery is beneficial to the stability of the pressing member during rotation, ensuring the juice extraction uniformity and juice extraction efficiency.

[0010] More preferably, the fixing ribs are at least two that are circumferentially disconnected. The discontinuity of the fixing ribs reduces the contact area between the fixing ribs and the fixing device, that is, the clamping groove, which is beneficial to reducing the friction force between the pressing member and the fixing device, reducing power loss, and improving the pressing efficiency.

[0011] More preferably, the above-mentioned fixing ribs are evenly distributed circumferentially. The uniform arrangement of the fixing ribs is beneficial to the force balance of the pressing member, preventing the pressing member from shaking or deviating during rotation and cleaning, which affects the service life of the pressing member.

[0012] More preferably, at least part of the part of the fixing rib in contact with the fixing device is made of wear-resistant material. Since the fixing rib and the fixing device move relative to each other for a long time, the contact part is made of wear-resistant material, which is beneficial to improving the service life of the pressing member and the pressing barrel, and at the same time reducing the friction coefficient.

[0013] More preferably, at least part of the part of the fixing rib in contact with the fixing device is made of metal material. The above design can reduce the friction coefficient between the fixing rib and the fixing device, and at the same time increase the service life of the pressing member 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 friction coefficient between the two will be greatly increased, and at the same time, since the fixing rib is too small and too thin, it is easy to break.

[0015] More preferably, the wall thickness of the above-mentioned fixing device is greater than or equal to 2 mm. Since the fixing device is worn for a long time, when the wall thickness is less than 2 mm, the position of the fixing device of the pressing barrel is easily worn through, reducing the service life; at the same time, the setting of the wall thickness also improves the strength at this place, preventing the clamping groove from breaking due to being too thin during the disassembly process.

[0016] More preferably, the axial gap between the fixing device and the fixing rib is 0.2 mm to 10 mm. When the axial gap between the two is less than 0.2 mm, the gap between the clamping groove and the fixing rib is too small, which will greatly increase the friction between the two, resulting in an increase in the power loss of the squeezing part; when the axial gap between the two is greater than 10 mm, the squeezing part is likely to shake, resulting in uneven juice extraction and increased wear on the transmission shaft.

[0017] More preferably, the rolling friction exists between the fixing device and the fixing rib. By providing rollers or balls between the fixing device and the fixing rib, the friction between the two can be effectively reduced, and the power loss can be decreased.

[0018] More preferably, a plain bearing is provided between the fixing device and the fixing rib. The provision of the plain bearing greatly reduces the friction between the fixing device and the fixing rib, and decreases the power loss.

[0019] Preferably, the squeezing part is the first squeezing net, and squeezing ribs are arranged on the inner wall of the first squeezing net. The first squeezing net squeezes through the inside, and presses the juice out through the first squeezing net to the outside. The arrangement of the squeezing ribs effectively improves the squeezing efficiency of the first squeezing net and increases the structural strength of the first squeezing net.

[0020] More preferably, squeezing rods are arranged inside the first squeezing net, and the squeezing rods are fixed on the base. The arrangement of the squeezing rods can cooperate with the first squeezing net to control the squeezing gap, and effectively improves the squeezing efficiency.

[0021] More preferably, rib strips are arranged on the squeezing rods. The arrangement of the rib strips can effectively improve the squeezing efficiency of the squeezing part and the squeezing rods.

[0022] More preferably, a first feeding hole is arranged at the top of the first squeezing net. The first feeding hole can conveniently let the material fall into the inside of the first squeezing net for convenient squeezing.

[0023] Preferably, the squeezing part is a screw, and a second squeezing net is arranged outside the screw, and the second squeezing net is fixed in the squeezing cup. The squeezing part is a screw, which squeezes the material from the outside of the screw, and cooperates with the second squeezing net to squeeze out the juice in the material.

[0024] More preferably, a second feeding hole is arranged around the upper part of the screw. The second feeding hole can conveniently let the material fall between the screw and the second squeezing net. Description of the Drawings
