Description

Technical Field

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

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

[0003] Juice extractors usually have two moving parts, one for pre-cutting and the other for juice extraction. Due to the unreasonable design of the two moving parts in existing juice extractors, the cutting effect is poor, and how to improve the working efficiency of the two moving parts has always been a problem for R & D personnel in this industry to think about. Summary of the Invention

[0004] The purpose of the present invention is to provide a juice extractor to solve the technical problem of the juice extraction efficiency of the juice extractor.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: to provide a juice extractor, including: a main body, a material bin, and a pressing bin. The material bin is communicated with the pressing bin. A cutting knife is arranged in the material bin, a screw is arranged in the pressing bin, a power unit is arranged on the main body, the power unit provides power for the cutting knife and the screw, the power unit is connected to the cutting knife and the screw through a first output shaft and a second output shaft respectively. The first output shaft and the second output shaft are both horizontally arranged, the first output shaft is located above the second output shaft, and at least part of the cutting knife is arranged with clearance at the position of the extension line of the first output shaft.

[0006] In the juice extractor of the present invention, by horizontally arranging the first output shaft and the second output shaft, and at the same time, there is clearance on the extension line of the first output shaft for the cutting knife, that is, there is a part of the middle of the cutting knife that is empty, so that materials larger than the radius of the material bin can also be quickly cut when entering, and since the falling direction of the material is not the axial direction of the first output shaft, it is basically not blocked by the first output shaft, thus improving the cutting efficiency and the overall pressing efficiency.

[0007] Preferably, the included angle formed by the first output shaft and the second output shaft is greater than or equal to 0 degrees and less than 90 degrees. That is, the first output shaft and the second output shaft can be parallel, or there can be a non-90-degree included angle, which is convenient for the cutting knife to cut the falling material in various postures and is beneficial to improving the cutting efficiency.

[0008] Preferably, the axial length of the clearance is greater than or equal to 10 mm. When the distance vacated in the middle of the cutting knife is less than 10 mm, that is, half of the first output shaft protrudes in the middle of the cutting knife, which is not conducive to the falling of large-sized materials and is easily blocked by the protruding first output shaft.

[0009] Preferably, the above-mentioned cutting knife includes at least one cutter body. The cutter body is mainly used for cutting operations. One or more cutter bodies cut the falling materials through rotational cycles, and the more the number of cutter bodies, the faster the cutting efficiency.

[0010] More preferably, the maximum overall rotation diameter of the above-mentioned cutter body is 10 mm - 500 mm. Since the cutter body rotates in the material bin, the maximum rotation diameter of the cutter body means the minimum inner diameter of the material bin. When the maximum rotation diameter of the cutter body is less than 10 mm, if the inner diameter of the material bin is also small, it will be very difficult to put the materials in; if the inner diameter of the material bin is much larger than 10 mm, then when the materials enter, a part of them will not be cut by the cutting knife and will directly fall into the pressing bin, and the cutting knife will lose its original function. When the maximum diameter of the cutter body exceeds 500 mm, it causes the material bin to be too large and makes the whole juicer too large.

[0011] More preferably, the above-mentioned cutter body is arranged in a curve. The cutter body is a curved line. When the materials fall, the cutter body will cut the materials from various angles, which is conducive to fully chopping the materials.

[0012] More preferably, the above-mentioned cutting knife includes at least two cutter bodies, and two or more cutter bodies are arranged at symmetrical positions on the extension line of the first output shaft. When the symmetrically arranged cutter bodies are cutting, it is easy to achieve force balance, making the force on the first output shaft relatively uniform, reducing the wear and power loss of the first output shaft.

[0013] More preferably, the material of the above-mentioned cutter body is plastic, metal or composite material. The material of the above-mentioned cutter body needs to be easy to clean and have certain strength requirements, so the above materials can meet the requirements of the cutter body of the cutting knife.

[0014] More preferably, the average cross-sectional area of the above-mentioned cutter body is greater than or equal to 3 square millimeters. When the average cross-sectional area of the cutter body is less than 3 square millimeters, the cutter body is too thin and is easily broken when cutting materials.

[0015] Preferably, the first output shaft and the second output shaft are connected by a transmission mechanism, and the transmission ratio of the transmission mechanism between the first output shaft and the second output shaft is 0.1 to 10. The transmission mechanism can make the first output shaft 10 times slower or 10 times faster than the second output shaft, but exceeding this ratio range will make the slower output shaft rotate too slowly, resulting in too low overall juicing efficiency.

[0016] More preferably, the transmission mechanism is fixed in the main machine. The transmission mechanism is fixed in the main machine and fixed together with the main machine, and the first output shaft and / or the second output shaft are docked and installed with the transmission mechanism on the main machine, so as to facilitate the cleaning of the material bin and the pressing bin.

[0017] More preferably, the transmission mechanism is fixed outside the material bin and / or the pressing bin, so that the axial reaction force of the first output shaft and the second output shaft will not act on the host, which is conducive to the fixation of the material bin and the pressing bin to the host.

[0041] Embodiment 1:

[0042] As Figure 1 , Figure 2 shown, Figure 1 is a schematic cross-sectional structure diagram of the juicer 1000 according to Embodiment 1 of the present invention, Figure 2It is a schematic diagram of the three-dimensional structure of the cutting blade 1210 and the screw 1310 of the juice extractor 1000 according to the first embodiment of the present invention.

[0043] This embodiment discloses a juice extractor 1000, including a main unit 1100, a material bin 1200, and a pressing bin 1300. A power unit 1110 is provided on the main unit 1100. A cutting blade 1210 is provided in the material bin 1200, and a screw 1310 is provided in the pressing bin 1300. The power unit 1110 provides power for the cutting blade 1210 and the screw 1310. The material bin 1200 is connected to the pressing bin 1300 up and down.

[0044] The power unit 1110 is connected to the transmission mechanism 1120 through transmission mechanism 1120, and the power unit 1110 transmits power to the cutter 1210 and the screw 1310. The cutter 1210 is provided with a first output shaft 1111, and the screw 1310 is provided with a second output shaft 1112. The transmission mechanism 1120 is connected to the first output shaft 1111 and the second output shaft 1112. The first output shaft 1111 and the second output shaft 1112 are both arranged horizontally and are parallel to each other. The first output shaft 1111 is located above the second output shaft 1112. The extension line of the first output shaft 1111 in the direction of the cutter 1210 is the avoidance 1211, that is, this piece has no shaft. In this way, it can prevent the material from being blocked by the first output shaft 1111 when it falls from the material bin 1200 into the pressing bin 1300. The length of the avoidance 1211 on the first output shaft 1111 is 148 mm. The transmission mechanism 1120 makes the transmission ratio of the first output shaft 1111 and the second output shaft 1112 3.

[0045] The cutting blade 1210 includes a blade body 1212. The maximum rotation diameter of the blade body 1212 is 150 mm. The blade body 1212 is arranged in a curved curve so as to cut through a larger range as possible, while at the same time being able to contact the material with a smaller area during cutting to ensure cutting strength. The blade body 1212 is made of stainless steel. The average cross-sectional area of the blade body 1212 is 3 square millimeters.

[0046] The transmission mechanism 1120 is fixed on the material bin 1200 and the pressing bin 1300. The second output shaft 1112 passes through the transmission mechanism 1120 and is connected to the power mechanism 1110. The second output shaft 1112 is a hexagonal shaft.

[0047] The juicer 1000 of this embodiment is provided with a horizontal first output shaft 1111 and a second output shaft 1112. At the same time, the first output shaft 1111 is provided with a clearance 1211 in the direction of the cutting knife 1210, so that the material can fall into the pressing chamber 1300 without obstruction after being cut from the material bin 1200, improving the squeezable size of the material and the pressing efficiency of the juicer 1000. At the same time, when assembling the material bin 1200 and the pressing chamber 1300 onto the main body 1100, since only the second output shaft 1112 needs to be connected, the installation is simple and convenient.

When assembled, the first output shaft 2111 and the second output shaft 2112 are respectively connected to the transmission mechanism 2120 on the main machine 2100. The first output shaft 2111 is a hexagonal shaft, and the second output shaft 2112 is an octagonal shaft. The second output shaft 2112 is designed to be octagonal to facilitate the simultaneous connection of the first output shaft 2111 and the second output shaft 2112.

[0054] The juice extractor (not shown) of this embodiment has substantially the same effect as the juice extractor 1000 of the first embodiment. In addition, the transmission mechanism 2120 of this embodiment is arranged inside the main machine 2100, which can avoid contaminating components such as gears inside the transmission mechanism 2120 when cleaning the material bin and the pressing bin.
