Detailed Description

As shown in fig. 1, the present invention provides a vacuum juicer including a base 17 for placing a juicing cup 20 (i.e., a raw material container) and a vacuum cap 14 capable of forming a sealed cavity with the juicing cup 20. The sealing ring 144 is arranged at the cover opening of the vacuum cover 14, and the vacuum cover 14 is driven by the closing driving device to move downwards until the sealing ring covers the opening of the juice extracting cup 20. The vacuum cover 14 is provided with a vacuum port 16 at the top, and the vacuum pump can pump air out of the cavity formed by the communication between the vacuum cover 14 and the juice extracting cup 20 through the vacuum port 16. A cutter extending inlet is formed in the center of the top of the vacuum cover 14, a juicing cutter 22 extends into the vacuum cover 14 through the cutter extending inlet and is connected with the cutter extending inlet in a sealing mode, after the vacuum pump extracts air in a cavity formed by the communication between the vacuum cover 14 and the juicing cup 20, the juicing cutter 22 extends into the juicing cup 20 to carry out juicing, and the juicing cutter retracts after juicing is completed. The extension and retraction of the juicing cutter 22 are driven by a closing driving device, the closing driving device comprises a first motor and a first screw 61 driven by the first motor, and further comprises a second motor 72 and a second screw 62 driven by the second motor 72, as shown in fig. 2, a first guide rod 51, a second guide rod 52, a third guide rod 53, the first screw 61 and the second screw 62 are respectively installed between a first installation plate 101 and a second installation plate 102 of the installation frame 1, the first motor is connected with the first screw 61 through a gear (the first motor is shielded by the second motor 72 beside the first motor in fig. 2), and the second motor 72 is connected with the second screw 62 through a gear, so that the first motor and the second motor 72 can respectively drive the first screw 61 and the second screw 62 to rotate. The top end of the vacuum cover 14 has three extending pieces, three

holes

141, 142, 143 are respectively opened on the three extending pieces, and the

holes

141, 142, 143 are respectively passed by the first guide rod 51, the second guide rod 52, and the first screw 61. The inner wall of the hole 143 has a screw thread which is engaged with the first screw 61 so that the vacuum housing 14 in which the extension piece is fitted over the first screw 61 can move up and down along the first screw 61 when the first motor drives the first screw 61 to rotate. The juicing cutter 22 is mounted on the cutter mounting plate 9, three holes 91, 92 and 93 are formed in the cutter mounting plate 9, and the holes 91, 92 and 93 are respectively used for the first guide rod 51, the second screw rod 62 and the third guide rod 53 to pass through. The inner wall of the hole 92 has a thread which is engaged with the second screw 62 so that the cutter mounting plate 9 fitted over the second screw 62 can move up and down along the second screw 62 when the second motor 72 drives the second screw 62 to rotate through the gear. In this embodiment, the relative movement between the juice extracting cutter 22 and the juice extracting cup 20 may be realized by fixing the juice extracting cutter 22 and driving the juice extracting cup 20 to move toward the juice extracting cutter 22 by other driving devices, or the relative movement between the vacuum cover 14 and the juice extracting cup 20 may be realized by fixing the vacuum cover 14 and driving the juice extracting cup 20 to move toward the juice extracting cutter 22 by other driving devices.

As shown in fig. 2, the first mounting plate 101 is provided with a hole 8, the hole 8 is penetrated by a third motor 73 for driving the juice extracting knife 22 to rotate, the third motor 73 is mounted on the knife mounting plate 9, and when the knife mounting plate 9 moves to the top end of the second screw 62, the third motor 73 moves to the upper side of the first mounting plate 101 of the mounting frame 1 through the hole 8. The hole 8 is also used for passing through a vacuum port 16 and a spiral nozzle 15 which are arranged on the top of the vacuum juicer, and when the top of the vacuum cover 14 moves to the top end of the first screw rod 61, the spiral nozzle 15 and the vacuum port 16 simultaneously move to the upper part of the first mounting plate 101 of the mounting frame 1 through the hole 8. When the top of the vacuum cap 14 is moved to the bottom end of the first screw 61, the vacuum cap 14 is moved to a position where the packing ring covers the opening of the juice extracting cup 20 (i.e., the ingredient container).

In the foregoing, the gear protection cover 2, the screw protection cover 3 and the motor protection cover 4 are respectively arranged on the peripheries of the screw, the gear and the motor, and the vacuum juicer provided with the gear protection cover 2, the screw protection cover 3 and the motor protection cover 4 is shown in fig. 3.

As shown in fig. 4, the juice extracting tool 22 includes a tool bar 10, a blade 11, a guard cylinder 12, and a guard cover 13 serving as a stopper. Specifically, the third motor 73 is connected to the cutter bar 10 through a coupling, the bottom of the cutter bar 10 is connected to the blade 11, and the exterior of the cutter bar 10 is sleeved with the protective cylinder 12. The bottom end of the guard cylinder 12 has a guard 13 that can shield the blade 11 inside. As shown in fig. 5, the protective cover 13 includes a mounting plate 131 and four anti-touch posts 132, the four anti-touch posts 132 are circumferentially distributed on the circular mounting plate 131, and the lower ends of the anti-touch posts 132 are lower than the lower ends of the blades 11 (see fig. 4), so as to prevent the blades 11 from scratching the bottom of the juice extracting cup 20. Because there is a gap between two adjacent anti-touch posts 132, fruit can pass through the gap and enter the inside of the protective cover 13, so that the use of the protective cover 13 does not affect the rotation of the blade 11 to cut fruit.

As shown in figure 2, the top of the vacuum cover 14 is provided with a spiral spray head 15, the spiral spray head 15 is used for spraying water downwards from the top to wash the juicing cutter, in order to prevent water flow splashing when washing the cutter, the edge of the vacuum cover 14 extends to form an extension part 21 (see figure 1) which can be contacted with the base, the vacuum cover 14 and the extension part 21 together cover the juicing cutter 22, and the two parts together form an anti-sputtering cover 23.

The working process of the vacuum juicer is as follows: the juicing cup 20 containing fruits is placed on the base 17, the first motor drives the anti-sputtering cover 23 to move downwards to a position covered with the base 17, and the sealing ring 144 abuts against the cup opening of the juicing cup 20, so that the juicing cup 20 and the upper part (namely the vacuum cover 14) of the anti-sputtering cover 23 form a closed cavity together. Because the sealing ring 144 is located at the opening of the vacuum cover 14 (the part below the sealing ring 144 is the extending part 21 of the anti-sputtering cover 23), and a space for accommodating the blade 11 is formed between the cup opening and the top of the vacuum cover 14, the blade 11 located inside the vacuum cover 14 does not enter the juicing cup 20 but stays above the cup opening, and the situation that the juicing taste is poor due to the fact that the blade 11 contacts with fruits in a non-vacuum state is avoided. In order to reserve a space above the cup opening for accommodating the blade 11, a certain distance is reserved between the cup opening of the juicing cup 20 and the bottom of the mounting frame 1, and if the juicing cup 20 is taken by a manipulator, the distance provides a movement space for the automatic operation of the manipulator, so that the vacuum juicer can be suitable for full-automatic equipment. After the juice extracting cup 20 and the vacuum cover 14 form a closed cavity, the vacuum pump uses the vacuum port 16 installed on the top of the vacuum cover 14 to draw air in the closed cavity to form a vacuum environment. The second motor 72 then drives the juicing cutter 22 to move downwards, and the third motor 73 drives the blade 11 to rotate, so as to realize juicing in a vacuum environment. Because the lower end of the anti-touch column 132 is lower than the lower end of the blade 11, when the juicing cutter 22 moves down to the bottom of the juicing cup 20, the blade 11 can not scratch the bottom of the cup, so that the disposable paper cup can be used as the juicing cup 20, and the use in occasions of automatically selling fruit juice is convenient. Moreover, tests show that the protective cover 13 can prevent fruits from moving above the blade 11 without cutting, so that all fruits are cut by the blade 11, and the fruit juice with finer taste is obtained. After the juice extraction is completed, the electromagnetic valve is used for deflating the sealed cavity through the vacuumizing interface 16 to recover the air pressure environment in the sealed cavity, then the first motor and the second motor 72 respectively drive the anti-sputtering cover 23 and the juice extracting cutter 22 to move upwards, so that the spiral nozzle 15, the vacuumizing interface 16 and the third motor 73 all pass through the hole 8 to move to the position above the first mounting plate 101 of the mounting frame 1, and a user can take the juice extracting cup 20 placed on the base 17. After the juice extracting cup 20 is taken away, the first motor and the second motor 72 respectively drive the anti-sputtering cover 23 and the juice extracting cutter 22 to move downwards, the anti-sputtering cover 23 returns to the position covered with the base 17, the juice extracting cutter 22 also resets to the position capable of extending into the bottom of the juice extracting cup 20, then the third motor 73 drives the juice extracting cutter 22 to rotate, and the spiral nozzle 15 arranged at the top of the vacuum cover 14 simultaneously sprays water to wash the juice extracting cutter 22. Compared with the existing vacuum juice extractor, the vacuum juice extractor realizes the automatic flushing function, and the anti-sputtering cover 23 comprises the vacuum cover 14 and the extension part 21, so that the anti-sputtering cover 23 can form a closed cavity with the juice extracting cup 20 for vacuum juice extraction and also prevent water flow from splashing during flushing. After the washing is completed, the first motor and the second motor 72 respectively drive the anti-sputtering cover 23 and the juicing cutter 22 to move upwards, so that the spiral nozzle 15, the vacuumizing interface 16 and the third motor 73 all move to the position above the first mounting plate 101 of the mounting frame 1 through the hole 8 to wait for the next juicing operation.

As shown in fig. 6, the base 17 has a bottom plate 171, a drain hole 172 having the same shape as the bottom surface of the vacuum chamber 14 is formed in the bottom plate 171, and a ring 173 and a ring 174 are provided in the drain hole 172. The inner diameter of the ring 173 is smaller than the diameter of the bottom surface of the juice extracting cup 20, and the outer diameter of the ring 173 is larger than the diameter of the bottom surface of the juice extracting cup 20, so that the ring 173 can carry the juice extracting cup 20. The inner diameter of the ring 174 is larger than the outer diameter of the bottom nozzle 18, so that the ring 174 does not obstruct the water flow from the bottom nozzle 18, and the outer diameter of the ring 174 is smaller than the inner diameter of the ring 173. The circular ring 174, the circular ring 173 and the water discharge hole 172 are concentric, and the circular ring 174, the circular ring 173 and the bottom plate 171 are sequentially welded together by the connecting rod 175 to form a water discharge structure, which can receive the juice extracting cup 20 and help to discharge water. The base 17 also has a fence 176 with an inner diameter slightly larger than the diameter of the bottom surface of the juice extracting cup 20, the fence 176 is welded to the ring 173 to form an anti-tilting structure, so that the fence 176 prevents the juice extracting cup 20 from tilting when the juice extracting cup 20 is placed on the base 17. As shown in fig. 7, the base 17 further includes an umbrella-shaped drain guide 177, the center of the drain guide 177 is positioned on the same vertical line as the center of the circular ring 174, and the drain guide 177 is welded to the connecting rod 175 by a connecting rod 178 so as to guide the water flowing out of the drain hole 172 to a drain position. The drain guide 177 is further provided with a passage 179 for the bottom nozzle 18 to pass through, so as to install the bottom nozzle 18 at the central position of the drain guide 177, the bottom nozzle 18 is above the drain guide 177, but the top of the bottom nozzle 18 is not higher than the circular ring 174, the elbow 19 is below the drain guide 177, the bottom nozzle 18 and the elbow 19 are respectively provided with matching screw threads, the direct butt joint of the bottom nozzle 18 and the elbow 19 is realized through the screw threads, and the drain guide 177 is clamped at the butt joint of the bottom nozzle 18 and the elbow 19, so as to realize the installation of the bottom nozzle 18 on the base 17. The bottom spray head 18 sprays water upwards from the bottom to wash the juicing cutter 22, the spiral spray head 15 sprays water downwards from the top to wash the juicing cutter 22, and the matching of the spiral spray head 15 and the bottom spray head 18 can clean the upper surface and the lower surface of the blade 11. The components of the base 17 are connected by welding, but if a die casting process is used, the structure of the base 17 can be integrally formed without welding.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
