Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to a screw-in squeezing juice extraction mechanism and a juicer using the mechanism. Background Art

[0002] Juicers, developed based on conventional juicers, primarily work by converting fruit pulp into juice for a more palatable and convenient drinking experience. Juicers utilize low-speed spiral extrusion technology, with the lowest possible speed, typically operating at around 75 revolutions per minute. This squeezes juice out slowly, like squeezing a towel, without damaging the fruit's cellular structure and preserving its nutrients. Existing juicers typically feature a cutter, which is placed within a mixing chamber for cutting. However, the chamber's dimensions are fixed, leaving a gap between the chamber wall and the cutter. This allows some fruit pulp to cling to the chamber wall, resulting in a low juice yield. Using a push rod to remove the clinging pulp can easily cause the cutter to hit the push rod, making it unsafe to use. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a screw-in squeeze juice extraction mechanism with high safety, high juice yield, portability and convenience of use, and a juicer using the mechanism.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A rotary precession squeeze juice extraction mechanism includes a drive motor, a squeeze turntable and a squeeze barrel. The output end of the drive motor is dynamically connected to the squeeze turntable for driving the squeeze turntable to rotate. The squeeze turntable is movably arranged in the squeeze barrel through a rotary precession mechanism and can move the squeeze barrel closer to or away from the squeeze turntable by rotation. A liquid outlet hole is provided at the bottom of the squeeze barrel.

[0006] As a further improvement of the above technical solution:

[0007] A plurality of groups of first extrusion ribs are formed on a side of the extrusion turntable opposite to the extrusion cylinder, and a plurality of groups of second extrusion ribs are formed on a side of the bottom of the extrusion cylinder opposite to the extrusion turntable.

[0008] The rotational precession mechanism includes a convex shaft arranged on the outer periphery of the extrusion turntable and an internal thread sliding groove arranged on the inner wall of the extrusion cylinder, and the convex shaft is slidably connected in the internal thread sliding groove.

[0009] The extrusion turntable includes an upper cover and a chassis. Several groups of mounting slots are provided in the chassis. Elastic return parts are provided in the mounting slots. The convex shaft is provided in the mounting slots. One end of the convex shaft abuts against the elastic return part, and the other end passes through the chassis.

[0010] An anti-slip mechanism is further provided between the convex shaft and the chassis. The anti-slip mechanism comprises an anti-slip convex portion provided on the convex shaft and an anti-slip abutting portion provided in the chassis.

[0011] The top of the extrusion cylinder is provided with an introduction groove for allowing the convex shaft to enter the internal thread sliding groove.

[0012] A juicer comprises a cup body and a cup cover, wherein the cup body is provided with the above-mentioned screw-in squeezing and juicing mechanism.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 6As shown, the rotary precession squeeze juice extraction mechanism of this embodiment includes a drive motor 1, a squeeze turntable 2, and a squeeze barrel 3. The output end of the drive motor 1 is connected to the squeeze turntable 2 for driving the squeeze turntable 2 to rotate. The squeeze turntable 2 is movably arranged in the squeeze barrel 3 by a rotary precession mechanism 4, and can move the squeeze barrel 3 closer to or away from the squeeze turntable 2 by rotation. A liquid outlet hole 301 is provided at the bottom of the squeeze barrel 3. The rotary precession squeeze juice extraction mechanism includes a drive motor 1, a squeeze turntable 2, and a squeeze barrel 3. The squeeze turntable 2 and the squeeze barrel 3 are connected by a rotary precession mechanism 4. As the squeeze turntable 2 rotates, the squeeze barrel 3 is driven to move closer to or away from the squeeze turntable 2, thereby changing the size of the stirring chamber. During the rotation, the pulp hanging on the wall can be pushed down for concentrated squeezing and stirring, replacing the technical solution of cutting by a cutter in the prior art. It has the advantages of simple structure, good convenience, high safety, and high juice yield.

[0033] Preferably, a plurality of groups of first extrusion ribs 5 are formed on the side of the extrusion turntable 2 opposite the extrusion barrel 3, and a plurality of groups of second extrusion ribs 6 are formed on the bottom side of the extrusion barrel 3 opposite the extrusion turntable 2. In this embodiment, as the extrusion turntable 2 rotates, the extrusion barrel 3 moves toward the extrusion turntable 2, and the space between the extrusion turntable 2 and the extrusion barrel 3 is gradually compressed. At the same time, the first extrusion ribs 5 on the extrusion turntable 2 stir the fruit pulp as it rotates, and the second extrusion ribs 6 at the bottom of the extrusion barrel 3 anchor the fruit pulp, preventing the fruit pulp from rotating with the rotation of the extrusion turntable 2, thereby improving stirring efficiency.

[0034] Preferably, the rotary precession mechanism 4 includes a protruding shaft 401 provided on the outer periphery of the extrusion turntable 2 and an internally threaded groove 402 provided on the inner wall of the extrusion cylinder 3, and the protruding shaft 401 is slidably connected to the internally threaded groove 402. In this embodiment, the protruding shaft 401 and the extrusion turntable 2 are separated, that is, the protruding shaft 401 can be extended and retracted relative to the extrusion turntable 2. In other embodiments, the protruding shaft 401 and the extrusion turntable 2 can also be formed in an integral manner, and the present invention is not limited to this embodiment.

[0035] Preferably, the extrusion turntable 2 includes an upper cover 201 and a chassis 202, and several groups of mounting slots 203 are provided in the chassis 202. Elastic return members 204 are provided in the mounting slots 203, and the convex shaft 401 is provided in the mounting slots 203. One end of the convex shaft 401 abuts against the elastic return member 204, and the other end passes through the chassis 202, so that the convex shaft 401 can elastically expand and contract within a certain range, which can reduce the impact and vibration during the extrusion process and reduce the risk of structural damage and failure. The extension length can be adjusted during use, and it is suitable for internal threaded slide grooves 402 with different groove depths, and has high flexibility in use.

[0036] Preferably, an anti-slip mechanism 7 is further provided between the cam 401 and the chassis 202. The anti-slip mechanism 7 includes an anti-slip protrusion 701 provided on the cam 401 and an anti-slip abutment 702 provided in the chassis 202. When the anti-slip protrusion 701 abuts against the anti-slip abutment 702, the cam 401 can be prevented from moving further outward, thereby preventing the cam 401 from falling out of the chassis 202 and being lost.

[0037] Preferably, the top of the extrusion cylinder 3 is provided with an introduction groove 8 for connecting the convex shaft 401 to the internal threaded groove 402. In this embodiment, the introduction groove 8 is arranged in the vertical direction, so that the assembly between the extrusion turntable 2 and the extrusion cylinder 3 is simple and convenient.

[0038] like Figure 7 and Figure 8 As shown, the juicer of this embodiment includes a cup body 100 and a cup lid 200. The cup body 100 is provided with the aforementioned screw-in squeezing and juicing mechanism. During the juicing process, as the squeezing cylinder 3 moves toward the squeezing turntable 2, the liquid storage space within the cup body 100 gradually increases. Therefore, the height of the drive motor 1 and the squeezing turntable 2 within the cup body 100 can be set relatively low. This results in a relatively low overall height of the juicer, a small footprint, and the advantages of being compact, portable, and convenient to use.

[0039] Preferably, the cup cover 200 is fixedly connected to the drive motor 1, and a guide mechanism 9 is provided between the extrusion cylinder 3 and the cup body 100. The guide mechanism 9 includes a guide rail 901 provided on the inner wall of the cup body 100 and a guide groove 902 provided on the outer wall of the extrusion cylinder 3. In this embodiment, a control button electrically connected to the drive motor 1 is provided on the cup cover 200. The control button can be used to drive the drive motor 1 to realize conventional functions such as starting, forward rotation, reverse rotation, and stopping. The operation is simple and convenient. When the extrusion cylinder 3 is installed in the cup body 100, the guide groove 902 on the extrusion cylinder 3 is slidably connected to the guide rail 901 in the cup body 100, so that the extrusion cylinder 3 can only move back and forth in the axial direction, and will not be driven to rotate with the rotation of the extrusion turntable 2, which is conducive to improving the working efficiency of the screw-in extrusion and juicing mechanism.

[0040] Preferably, a limiting mechanism 10 is provided between the extrusion cylinder 3 and the cup body 100. The limiting mechanism 10 includes a limiting abutment 1001 provided on the inner wall of the cup body 100 and a limiting convex portion 1002 provided on the outer wall of the extrusion cylinder 3. In this embodiment, the limiting abutment 1001 is formed in the cup body 100, and the limiting convex portion 1002 is formed on the outer wall of the extrusion cylinder 3. When the extrusion cylinder 3 is placed in the cup body 100, the limiting convex portion 1002 abuts against the limiting abutment 1001, so that a liquid storage space is formed between the bottom of the extrusion cylinder 3 and the bottom of the cup body 100, facilitating the juice to fall into the cup body 100 through the liquid outlet through-hole 301. It should be noted that in this embodiment, the guide groove 902 is provided on the limiting convex portion 1002.

[0041] During actual use, the user first places the extrusion cylinder 3 in the cup body 100. At this time, the guide groove 902 on the extrusion cylinder 3 is slidably connected with the guide rail 901 in the cup body 100, so that the extrusion cylinder 3 can only move back and forth along the axial direction. The limiting protrusion 1002 on the extrusion cylinder 3 is in contact with the limiting abutment 1001 in the cup body 100, so that a liquid storage space is formed between the bottom of the extrusion cylinder 3 and the bottom of the cup body 100. The user places the pulp of fruits such as watermelon, orange, and grape into the extrusion cylinder 3, and then the user installs the cup cover 200 and the drive motor 1 and the extrusion turntable 2 thereon on the cup body 100. At this time, the convex shaft 401 on the extrusion turntable 2 is connected to the internal thread slide groove 4 along the guide groove 8 on the extrusion cylinder 3. 02, and then the user drives the squeezing turntable 2 to rotate forward through the control button, and the convex shaft 401 slides along the internal threaded groove 402, thereby driving the squeezing cylinder 3 to move toward the squeezing turntable 2, and then squeezing the pulp in the squeezing cylinder 3. At the same time, the first squeezing rib 5 on the squeezing turntable 2 and the second squeezing rib 6 in the squeezing cylinder 3 cooperate to stir the pulp, effectively improving the juice yield of the pulp, and the juice falls into the cup body 100 through the liquid outlet hole 301; after the juicing is completed, the squeezing turntable 2 is driven to reverse, thereby driving the squeezing cylinder 3 to move away from the squeezing turntable 2, and finally the squeezing cylinder 3 is separated from the squeezing turntable 2, and the pomace in the squeezing cylinder 3 is taken out. The above is a complete juicing process of the utility model.

[0042] Preferably, the cup cover 200 and the cup body 100 are detachably connected via a threaded connection mechanism 11, which can effectively improve the connection stability between the cup cover 200 and the cup body 100, making them difficult to separate and fall off, and the installation and disassembly process is convenient and quick.

[0043] The above is only a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited to the above embodiment. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of the present invention should also be considered as the scope of protection of the present invention.
