[0020] This invention discloses a lifting electric mixer for food processing to solve the problems mentioned above.

[0021] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0022] Please see Figure 1-6 A lifting electric mixer for food processing includes: a body 1, a stirring rod 2, a scraper 3, a collar 4, a pull-back assembly, a lifting assembly, and a connecting assembly; The machine body 1 is used to assemble a mixer. The machine body 1 has an electric lifting structure. The stirring rod 2 is connected to the machine body 1. The scraper 3 is arranged around the outside of the stirring rod 2. Multiple scraper 3 form a complete scraper ring. There are two collars 4, which are slidably sleeved on the outside of the stirring rod 2. The pull-back assembly connects the collar 4 to the scraper 3 and is used to pull the scraper 3 back towards the stirring rod 2. The lifting assembly is located on the upper part of the stirring rod 2 and is used to drive the collar 4 to move along the stirring rod 2. The connecting assembly is used to connect the two collars 4.

[0023] In use, the stirring rod 2 is driven to rotate by the body 1 to stir the material in the barrel. The lifting component drives the collar 4, pull-back component, and scraper 3 to descend, causing the scraper ring composed of multiple scrapers 3 to move down and scrape the material attached to the inner wall of the barrel above the liquid surface. As the scraper ring is immersed below the liquid surface, the material above the liquid surface is brought into the liquid surface, so that it can be fully mixed. After the scraper ring is immersed below the liquid surface, the connection component to the two collars 4 is disconnected. The lifting component pulls the upper collar 4 and its connected pull-back component and scraper 3 to rise, so that it is separated from the lower collar 4 and its connected pull-back component and scraper 3. The adjacent scrapers 3 are staggered and distributed vertically. Then, the pull-back component pulls the scraper 3 away from the barrel wall. At this time, the pull-back component and scraper 3 form stirring blades, which can improve the stirring effect of the stirring rod 2. If the scraper ring is in close contact with the barrel wall, firstly, the friction with the barrel wall will cause the resistance of the stirring rod 2 to be large, affecting the stirring effect; secondly, some material will be stuck between the bottom of the scraper ring and the barrel wall, forming a stirring dead zone. This part of the area will not be fully stirred, affecting the stirring effect. Therefore, by pulling the scraper 3 back, it is removed from the barrel wall, thus preventing the above-mentioned problems, ensuring the mixing effect, and finally bringing the suspended material attached to the barrel wall into the liquid, so as to achieve thorough mixing.

[0024] In one specific implementation, refer to Figure 2-6 The pull-back assembly includes: housing 6, connecting rod 7, sliding plate 8, spring 9, and locking assembly; The housing 6 is fixedly connected to the outside of the collar 4. One end of the connecting rod 7 is slidably disposed inside the housing 6, and the other end is connected to the scraper 3. A sealing ring is provided at the junction of the connecting rod 7 and the housing 6 to prevent material from entering the housing 6. The slide plate 8 is fixedly connected to the end of the connecting rod 7 located inside the housing 6. The slide plate 8 is rectangular. The spring 9 is sleeved on the outside of the connecting rod 7. The two ends of the spring 9 are fixedly connected to the slide plate 8 and the inner wall of the housing 6, respectively. The locking component is disposed on the housing 6 to lock the position of the slide plate 8.

[0025] The locking component is released from locking the slide plate 8. At this time, the compressed spring 9 moves the slide plate 8, connecting rod 7, and scraper 3, causing the scraper 3 to move towards the stirring rod 2 and away from the barrel wall.

[0026] In one specific implementation, refer to Figure 5 The locking assembly includes: housing 10, connecting plate 11, locking block 12, and first electromagnet 13; The housing 10 is fixedly connected to the outside of the sleeve 6. The connecting plate 11 is slidably disposed inside the housing 10. The locking block 12 is fixedly connected to the bottom of the connecting plate 11. The sliding plate 8 has a locking groove corresponding to the locking block 12. The locking block 12 extends into the locking groove. The first electromagnet 13 is fixedly connected to the top wall of the housing 10. It can attract the connecting plate 11 when energized. The connecting plate 11 is made of magnetic stainless steel and can be magnetically attracted. The size of the connecting plate 11 is adapted to the inner cavity size of the housing 10.

[0027] When the first electromagnet 13 is energized to make it magnetic, the attraction plate 11 carries the card block 12 away from the card slot, thus releasing the fixation of the slide plate 8.

[0028] In one specific implementation, refer to Figure 5 The bottom of the card block 12 is provided with a slope, which faces the stirring rod 2.

[0029] When the first electromagnet 13 is de-energized, the connecting plate 11 and the locking block 12 descend under the action of gravity, pulling the scraper 3 to reset the connecting rod 7 and the slide plate 8. When the slide plate 8 contacts the inclined plane, the locking block 12 and the connecting plate 11 are pushed up by the inclined plane. When the locking block 12 is aligned with the slot, the locking block 12 and the connecting plate 11 descend under the action of gravity, and the locking block 12 enters the slot, thus locking the slide plate 8.

[0030] In one specific implementation, refer to Figure 6 The connecting components include: a second electromagnet 17 and a pull rope 18; The second electromagnet 17 is located inside the upper collar 4, and the lower collar 4 is made of stainless steel. When the second electromagnet 17 is energized, it can attract the lower collar 4. The pull rope 18 connects the upper and lower collars 4.

[0031] When the second electromagnet 17 is de-energized and loses its magnetism, the upper and lower collars 4 can separate. When the upper collar 4 rises to its reset position, it can move along with the lower collar 4 by relying on the pull rope 18.

[0032] In one specific implementation, refer to Figure 2-3 The connecting rod 7 is rotatably connected to the scraper 3. A stop block 14 is fixedly connected to the inner side of the scraper 3. A baffle 15 is fixedly connected to the outer side of the connecting rod 7. A positioning rod 16 is threadedly connected to the connecting rod 7. One end of the positioning rod 16 is threadedly connected to the stop block 14. The weight of the scraper 3 on the side closer to the baffle 15 is greater than the weight on the side farther away from the baffle 15.

[0033] By restricting the stop 14 with the positioning rod 16, the scraper 3 is kept in a horizontal state when the upper and lower collars 4 are reassembled and reset, which facilitates the reassembly of the scraper 3 into a scraper ring. The positioning rod 16 is rotated to move away from the stop 14. When the scraper 3 leaves the barrel wall, it deflects and rotates to the heavier side under the action of gravity. The scraper 3, along with the stop 14, comes into contact with the baffle 15, making the scraper 3 tilted. Then, as the scraper 3 rotates with the stirring rod 2, its bottom slope faces the liquid, which pushes the material downward, thereby improving the mixing effect of the material.

[0034] In one specific implementation, refer to Figure 4-6 The lifting assembly includes: a motor 20, a winding reel, and a winding rope 19; The motor 20 is symmetrically fixed to the outside of the stirring rod 2, the winding reel is fixedly connected to the output shaft of the motor 20, and the winding rope 19 fixes the winding reel to the upper collar 4. The weight of the collar 4 is sufficient to carry the scraper 3 into the material when it falls.

[0035] The output shaft of motor 20 drives the take-up reel to rotate in the forward direction, releasing the take-up rope 19. Under the action of gravity, the collar 4 descends. The output shaft of motor 20 drives the take-up reel to rotate in the reverse direction, causing the take-up rope 19 to pull the collar 4 upward.

[0036] The stirring rod 2 and the collar 4 are both equipped with built-in batteries (not shown in the figure) to power the motor 20, the first electromagnet 13, and the second electromagnet 17.

[0037] In one specific implementation, refer to Figure 2-4 The stirring rod 2 has symmetrically opened limit grooves on its outside, and the inner side of the collar 4 is connected to the limit block 5, which is slidably set in the limit groove.

[0038] This allows the stirring rod 2 to rotate in conjunction with the limiting groove, causing the limiting block 5 and the collar 4 to rotate as well.

[0039] In one specific implementation, refer to Figure 2-3 The scraper 3 connected to the upper connecting rod 7 and the scraper 3 connected to the lower connecting rod 7 are arranged adjacent to each other. When the two collars 4 are separated, the adjacent scrapers 3 are staggered.

[0040] In one specific implementation, refer to Figure 6 The bottom of the upper limiting block 5 is provided with a storage groove. One end of the pull rope 18 is connected to the top wall of the storage groove, and the other end is connected to the lower limiting block 5. The pull rope 18 is located in the storage groove, and the size of the storage groove is sufficient to accommodate the pull rope 18.

[0041] The presence of the storage slot prevents the pull cord 18 from obstructing the merging of the two collars 4 when they are joined together.

[0042] Working principle: During use, the stirring rod 2 is driven by the machine body 1 to rotate and stir the material in the barrel. The motor 20 is started, and its output shaft rotates the winding reel in the forward direction, releasing the winding rope 19. Under the action of gravity, the collar 4, the housing 6, the connecting rod 7, and the scraper 3 descend, causing the scraper ring composed of multiple scrapers 3 to move downward and scrape the material attached to the inner wall of the barrel above the liquid surface. As the scraper ring is immersed below the liquid surface, this part of the material above the liquid surface is brought into the liquid surface, so that it can be fully mixed. After the scraper ring is immersed below the liquid surface, the second electromagnet 17 is de-energized and demagnetized. At this time, the upper and lower collars 4 can be separated. At this time, the limiting block 5 on the lower collar 4 is in contact with the bottom wall of the limiting groove and cannot move down. The motor is started. The machine 20 causes its output shaft to rotate in the opposite direction with the winding reel, causing the winding rope 19 to pull the upper collar 4 upward, which in turn causes the connected housing 6, connecting rod 7, and scraper 3 to rise, causing adjacent scrapers 3 to separate and stagger. Finally, the adjacent scrapers 3 are staggered and distributed vertically. The first electromagnet 13 is energized to make it magnetic, causing the attraction connecting plate 11 to take the locking block 12 away from the slot, thus releasing the fixation of the slide plate 8. At this time, the compressed spring 9 moves the slide plate 8, connecting rod 7, and scraper 3, causing the scraper 3 to move towards the stirring rod 2 and away from the barrel wall. Then the first electromagnet 13 is de-energized, and the locking block 12 descends under the action of gravity. At this time, the housing 6, connecting rod 7, and scraper 3 form stirring blades, which can improve the stirring effect of the stirring rod 2. If the scraper ring is in close contact with the barrel wall, firstly, the friction with the barrel wall will cause the resistance of the stirring rod 2 to be large, affecting the stirring effect; secondly, some material will be stuck between the bottom of the scraper ring and the barrel wall, forming a stirring dead zone. This part of the area will not be fully stirred, affecting the stirring effect. Therefore, by pulling the scraper 3 back, it is removed from the barrel wall, thus preventing the above-mentioned problems, ensuring the mixing effect, and finally bringing the suspended material attached to the barrel wall into the liquid, so as to achieve thorough mixing. Before separating the positioning rod 16 from the stop block 14, when the scraper 3 leaves the barrel wall, under the action of gravity, the scraper 3 deflects and rotates to the heavier side. The scraper 3, along with the stop block 14, comes into contact with the stop plate 15, causing the scraper 3 to be in an inclined state. Then, as the scraper 3 rotates with the stirring rod 2, its bottom slope faces the liquid, causing the material to be squeezed downwards, thereby improving the mixing and stirring effect of the material. After mixing, the output shaft of motor 20 rotates in the opposite direction, causing the winding reel to rotate. This causes the winding rope 19 to pull the upper collar 4 upward, which in turn causes the pull rope 18 to pull the lower collar 4 upward, thus lifting the scraper 3 out of the barrel. After cleaning the above structure, the scraper 3 is pulled to reset the connecting rod 7 and the slide plate 8. When the slide plate 8 contacts the inclined plane, the clamping block 12 and the connecting plate 11 rise. When the clamping block 12 aligns with the slot, the clamping block 12 and the connecting plate 11 descend under the action of gravity. The locking block 12 enters the slot, locking the slide plate 8. At this time, the spring 9 is compressed, and then the scraper 3 is rotated to a horizontal state. The positioning rod 16 is rotated back to its original position, so that it engages with the stop block 14. This ensures that the scraper 3 is in a horizontal state when the upper and lower collars 4 are merged and reset. Then, the lower collar 4 is pushed to rise and abut against the upper collar 4. The second electromagnet 17 is energized to make it magnetic, so that it is fixed with the lower collar 4. At this time, the scraper 3 is reset, forming a complete scraper ring.
