Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a fruit puree maker. Background Technology

[0002] A fruit puree maker is a household appliance used to prepare frozen desserts or fruit products. It uses a mixing blade to cut and blend food to obtain a puree with a paste-like texture. It can provide users with desserts such as ice cream, frozen yogurt, or smoothies, and provide users with fruit puree products with a smooth and delicate taste.

[0003] Existing fruit puree machines include a rotating lifting seat for holding the material cylinder. This seat rotates and lifts the cylinder, allowing it to be rotatably assembled into the machine housing. The cutting tools inside the cylinder are then coupled to the output shaft within the housing. The user then releases the clamping lever in the cylinder cover by rotating it, unlocking the cutting tools and allowing the output shaft to guide them into the cylinder for cutting and mixing the food, thus completing the preparation of the fruit puree.

[0004] However, since the rotation and upward movement of the material cylinder and the unlocking movement of the cutter are independent of each other and have a strict sequence of actions, human factors can easily lead to misoperation during actual use, affecting the safety and working efficiency of the fruit puree machine. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a fruit puree machine that can effectively simplify the assembly of the material cylinder, thereby reducing the possibility of misoperation caused by human factors.

[0006] To solve the above-mentioned technical problems, the present invention provides a fruit puree maker, comprising: The machine body has an internally installed output shaft that can be raised, lowered, and rotated relative to each other, and the machine body is provided with a connecting seat, and the output shaft extends a predetermined length from the bottom of the connecting seat; A connecting turntable is provided, wherein the connecting seat has a spiral guide portion, the connecting turntable is rotatably connected to the spiral guide portion, the spiral guide portion has an assembly position and a fixing position, and the connecting turntable moves between the assembly position and the fixing position to move closer to or further away from the connecting seat. A material cylinder is suspended on the connecting turntable. A knife locking assembly is provided on the top of the material cylinder. A knife is connected to the knife locking assembly. A connecting hole is formed on the top of the material cylinder. The distance between the knife and the connecting hole is the same as the preset length. The knife locking assembly is used to separate the knife when the connecting turntable is in the fixed position.

[0007] As an improvement to the above solution, the assembly position is located below the fixed position, and a first height is formed between the assembly position and the fixed position. When the connecting turntable is located at the assembly position, a second height is formed between the locking knife assembly and the connecting seat, and the first height is greater than the second height.

[0008] As an improvement to the above solution, the locking knife assembly includes a pressing seat and at least two locking knife seats. The pressing seat protrudes outward from the material cylinder and is vertically slidably connected to the top of the material cylinder, while the locking knife seats are horizontally slidably connected to the top of the material cylinder. The bottom surface of the pressing seat facing the locking knife seat has a first abutting slope, and the top surface of the locking knife seat facing the pressing seat has a second abutting slope. The first abutting slope and the second abutting slope abut against each other and can slide relative to each other. The locking knife seats are symmetrically arranged on the material cylinder, and a first elastic element is provided between the two locking knife seats.

[0009] As an improvement to the above solution, a tool-holding protrusion is formed at the top of the barrel, and the tool is inserted into the tool-holding protrusion via a connector shaft, and the height of the tool-holding protrusion is greater than or equal to the height of the connector shaft; The side wall of the tool locking ring is provided with a locking hole. When the connecting turntable is in the assembly position, the tool locking seat is inserted into the locking hole and abuts against the tool.

[0010] As an improvement to the above solution, a locking post is formed on the side of the locking knife seat facing the locking knife protrusion ring. The cross-sectional area of ​​the locking post is smaller than the cross-sectional area of ​​the locking hole. A locking knife concave ring is formed on the insertion shaft. The height of the locking knife concave ring is greater than or equal to the height of the locking hole. The inner wall surface of the locking pin concave ring and the outer wall surface of the locking pin convex ring form a locking pin gap, and the horizontal length of the locking pin is greater than the locking pin gap.

[0011] As an improvement to the above solution, the bottom of the connecting turntable is formed with a connecting suspension groove and an installation notch, and the side of the material cylinder is formed with an installation boss. When the connecting turntable is in the assembly position, the installation boss is aligned with the installation notch. When the connecting turntable is in the fixed position, the installation boss rotates and embeds itself into the suspension groove.

[0012] As an improvement to the above solution, the connecting turntable is provided with a stop pin, the material cylinder is formed with an anti-rotation boss, the anti-rotation boss is formed with an anti-rotation surface facing a preset direction, the preset direction being the direction of the suspension groove towards the mounting notch; When the connecting turntable is in the assembly position, the stop pin is located above the anti-rotation boss; when the connecting turntable is in the fixed position, the stop pin abuts against the anti-rotation boss.

[0013] As an improvement to the above solution, the suspension groove forms a preset groove width, and when the connecting turntable is in the assembly position, a preset distance is formed between the stop pin and the anti-rotation surface, and the preset groove width is greater than or equal to the preset distance.

[0014] As an improvement to the above solution, the spiral guide portion is an inclined guide groove formed on the side of the connecting seat, the connecting turntable is connected to the connecting seat through the inclined guide groove, and the stop pin is slidably connected to the inclined guide groove. A second elastic element is provided between the stop pin and the connecting turntable, and an unlocking groove is formed in the fixed position. The unlocking groove is connected to the inclined guide groove, and the groove width of the unlocking groove is greater than the groove width of the inclined guide groove. When the connecting turntable is located in the fixed position, the stop pin is located in the unlocking groove.

[0015] As an improvement to the above solution, the connecting turntable is slidably connected to a limit switch, and when the connecting turntable is in the fixed position, the anti-rotation boss abuts against the limit switch.

[0016] Implementing this invention has the following beneficial effects: The fruit puree machine of this embodiment utilizes the cooperation between the connecting turntable and the spiral guide of the connecting seat to complete the assembly of the material cylinder from bottom to top. Simultaneously, during the assembly process, the inner top surface of the connecting seat engages with the locking blade assembly at the top of the material cylinder, unlocking the blade. This allows the assembly of the material cylinder and the unlocking of the blade to be performed in tandem. When assembling the material cylinder into the machine body, the user only needs to ensure that the output shaft is extended from the connecting seat and that the locking blade assembly at the top of the material cylinder is in the locked state, and then push the material cylinder and the connecting turntable to rotate relative to the connecting seat. This effectively simplifies the assembly process of the material cylinder, reducing errors caused by human factors and ensuring the safety and efficiency of the fruit puree machine.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0019] This invention provides a fruit puree maker, as shown in Figures 1 to 6. The fruit puree maker includes a machine body 1, a connecting turntable 2, and a material cylinder 3. The machine body 1 has an output shaft 11 that can be raised, lowered, and rotated relative to the material cylinder. The machine body 1 also has a connecting seat 12. The output shaft 11 extends a predetermined length from the bottom of the connecting seat 12 so that after the material cylinder 3 is assembled, the output shaft 11 can extend into the material cylinder 3 and connect with the cutter 32 of the material cylinder 3. The connecting seat 12 has a spiral guide portion 21. The connecting turntable 2 is rotatably connected to the spiral guide portion 21. The spiral guide portion 21 has an assembly position 22 and a fixed position 23. The connecting turntable 2 moves between the assembly position 22 and the fixed position 23 to move closer to or further away from the connecting seat 12.

[0020] The material cylinder 3 is suspended from the connecting turntable 2. A knife locking assembly 31 is provided on the top of the material cylinder 3, and a knife 32 is connected to the knife locking assembly 31. A connecting hole 33 is formed on the top of the material cylinder 3. The distance between the knife 32 and the connecting hole 33 is the same as the preset length, so that after the output shaft 11 is inserted into the connecting hole 33 of the material cylinder 3, it is convenient for the knife 32 to be connected to the output shaft 11. The knife locking assembly 31 is used to separate the knife 32 when the connecting turntable 2 is in the fixed position 23.

[0021] Specifically, as shown in Figures 3 to 6, when the connecting turntable 2 is in the assembly position 22, the locking tool assembly 31 is located below the connecting seat 12, and the locking tool assembly 31 locks the tool 32; when the connecting turntable 2 is in the fixed position 23, the inner top surface of the connecting seat 12 presses the locking tool assembly 31 to separate the locking tool assembly 31 from the tool 32.

[0022] In the fruit puree machine provided in this embodiment, when assembling the material cylinder 3 onto the machine body 1, the connecting turntable 2 can be moved to the assembly position 22, and then the material cylinder 3 is suspended in the connecting turntable 2. Subsequently, the connecting turntable 2 drives the material cylinder 3 from the assembly position 22 to the fixed position 23, so that the material cylinder 3 moves from bottom to top toward the connecting seat 12 of the machine body 1, and when the connecting turntable 2 moves to the fixed position 23, the assembly of the material cylinder 3 onto the machine body 1 is completed.

[0023] During the assembly of the material cylinder 3 from bottom to top, the locking blade assembly 31 at the top of the material cylinder 3 gradually approaches the inner top surface of the connecting shell, and when the connecting turntable 2 is about to move to the fixed position 23, the locking blade assembly 31 abuts against the inner top surface of the connecting shell. Subsequently, as the connecting turntable 2 continues to move towards the fixed position 23, the inner top surface of the connecting shell presses down on the locking blade assembly 31, causing relative movement between the locking blade assembly 31 and the material cylinder 3. Thus, under the linkage of the inner top surface of the connecting shell and the locking blade assembly 31, the locking blade assembly 31 separates from the blade 32, completing the unlocking action of the blade 32. The blade 32 can then be linked with the output shaft 11 extending into the material cylinder 3 to correspondingly complete the food preparation work inside the material cylinder 3.

[0024] Therefore, in this embodiment of the fruit puree machine, the connecting turntable 2 cooperates with the spiral guide part 21 of the connecting seat 12 to complete the assembly of the material cylinder 3 from bottom to top. Simultaneously, during the assembly of the material cylinder 3 from bottom to top, the inner top surface of the connecting seat 12 can cooperate with the locking blade assembly 31 at the top of the material cylinder 3 to complete the unlocking action of the blade 32. This allows the assembly of the material cylinder 3 and the unlocking of the blade 32 to be carried out in a coordinated manner. When assembling the material cylinder 3 into the machine body 1, the user only needs to confirm that the output shaft 11 is extended at the position of the connecting seat 12, and that the locking blade assembly 31 at the top of the material cylinder 3 is in the locked state, and then push the material cylinder 3 and the connecting turntable 2 to rotate relative to the connecting seat 12. This effectively simplifies the assembly action of the material cylinder 3, thereby reducing the possibility of misoperation due to human factors and ensuring the safety and working efficiency of the fruit puree machine.

[0025] It should be noted that the connecting hole 33 at the top of the barrel 3 is coaxially arranged with the cutter 32 and the output shaft 11 in the machine body 1, so that when the barrel 3 moves upward, the output shaft 11 extending from the connecting seat 12 can extend into the barrel 3 and connect with the cutter 32.

[0026] Specifically, the assembly position 22 is located below the fixed position 23, forming a first height between the assembly position 22 and the fixed position 23. When the connecting turntable 2 is located at the assembly position 22, a second height is formed between the locking blade assembly 31 and the connecting seat 12. The first height is greater than the second height. Therefore, when the connecting turntable 2 moves the material cylinder 3 from the assembly position 22 to the fixed position 23, the contact action between the locking blade assembly 31 at the top of the material cylinder 3 and the inner top surface of the connecting seat 12 can move to the fixed position 23 before the connecting turntable 2 does. Thus, the subsequent assembly process of the material cylinder 3 moving to the fixed seat can be synchronized with the action of pressing the locking blade assembly 31 against the inner top surface of the connecting seat 12. Furthermore, the assembly driving force of the material cylinder 3 and the unlocking driving force of the blade 32 are both provided by the driving force of the user pushing the material cylinder 3 and the connecting turntable 2 to rotate, ensuring a simplified assembly action of the material cylinder 3.

[0027] In this embodiment, to ensure that the locking tool assembly 31 can perform the unlocking action of the tool 32 in conjunction with the assembly process of the barrel 3, as shown in Figures 5 to 8, the locking tool assembly 31 includes a pressing seat 311 and at least two locking tool seats 312. The pressing seat 311 protrudes outward from the barrel 3 and is vertically slidably connected to the top of the barrel 3. The locking tool seats 312 are horizontally slidably connected to the top of the barrel 3. A first abutting inclined surface 3111 is formed on the bottom surface of the pressing seat 311 facing the locking tool seat 312, and a second abutting inclined surface 3121 is formed on the top surface of the locking tool seat 312 facing the pressing seat 311. The first abutting inclined surface 3111 and the second abutting inclined surface 3121 abut against each other and can slide relative to each other. The locking tool seats 312 are symmetrically arranged on the barrel 3.

[0028] Understandably, when the locking assembly 31 abuts against the inner top surface of the connecting shell, it abuts against the inner top surface of the connecting shell through the pressing seat 311. The inner top surface of the connecting shell applies downward pressure to the pressing seat 311, causing vertical relative sliding between the pressing seat 311 and the top of the material cylinder 3. At this time, with the cooperation of the second abutting inclined surface 3121 and the first abutting inclined surface 3111, the pressing seat 311 applies a lateral force to the locking seat 312, thereby pushing the symmetrically arranged locking seat 312 to slide horizontally relative to the top surface of the material cylinder 3 and away from the cutter 32, completing the unlocking action of the cutter 32, facilitating the connection of the cutter 32 with the output shaft 11, and allowing it to enter the material cylinder 3 under the drive of the output shaft 11.

[0029] The inclination angle of the first abutting inclined surface 3111 is equal to the inclination angle of the second abutting inclined surface 3121, and preferably 45°, to ensure that the first and second inclined surfaces cooperate to realize the equivalent conversion of the vertical pressure of the pressing seat 311 into the horizontal thrust of the locking knife seat 312. This corresponds to the equivalent conversion between the vertical displacement of the pressing seat 311 and the horizontal position of the locking knife seat 312, making it convenient for the user to complete the action of unlocking the knife 32 by controlling the displacement of the connecting turntable 2 and the material cylinder 3.

[0030] Furthermore, after the blade 32 completes its processing of the food, the output shaft 11 drives the blade 32 to return to the top of the barrel 3. To ensure that the locking blade seat 312 can re-lock the blade 32 after the barrel 3 is removed from the machine body 1, as shown in Figure 8, a first elastic element 3123 is provided between the two locking blade seats 312. The first elastic element 3123 is preferably a tension spring. When the pressing seat 311 pushes the symmetrical locking blade seats 312 away from each other, the symmetrical locking blade seats 312 can stretch the first elastic element 3123, so that the first elastic element 3123 is stretched and stores energy. After the barrel 3 is removed from the machine body 1, the pressing seat 311 is no longer under the pressure of the connecting shell, that is, the locking blade is no longer under the thrust. At this time, the elastic tension of the first elastic element 3123 can be used to pull the symmetrical locking blade seats 312 closer to each other and re-lock the locking blade seat 312 against the blade 32, thereby re-locking the blade 32 inside the barrel 3.

[0031] Furthermore, during the process of the locking seat 312 re-clamping the cutter 32, the second abutting inclined surface 3121 and the first abutting inclined surface 3111 cooperate, and the locking seat 312 can reset the pressing part to the top of the material cylinder 3 so that the tool 32 can be unlocked in conjunction when the material cylinder 3 is reassembled into the machine body 1.

[0032] As an optional embodiment, to facilitate the assembly of the first elastic member 3123 between symmetrical locking knife seats 312, as shown in FIG8, a connecting arm 3124 is formed in the locking knife seat 312, and a hanging hole is formed in the connecting arm 3124 for hooking the first elastic member 3123.

[0033] As an optional embodiment, as shown in Figures 8 and 9, in order to facilitate the horizontal sliding of the locking knife holder 312 relative to the material cylinder 3, a horizontal slide rail 3126 is formed on the top surface of the material cylinder 3, and a sliding groove 3125 is formed on the bottom surface of the locking knife holder 312. The cooperation between the horizontal slide rail 3126 and the sliding groove 3125 facilitates the pressing seat 311 to push the locking knife holder 312 to slide relative to the top surface of the material cylinder 3.

[0034] To facilitate vertical relative displacement between the pressure seat 311 and the barrel 3, as shown in Figure 9, a guide cover 37 is detachably connected to the top surface of the barrel 3. The pressure seat 311 is disposed inside the guide cover 37 and protrudes outward from the guide cover 37. The guide cover 37 has a vertical guide hole 371 coaxial with the cutter 32. The pressure seat 311 is slidably connected to the vertical guide hole 371 to provide vertical guidance for the pressure seat 311, facilitating vertical relative displacement between the pressure seat 311 and the barrel 3.

[0035] Furthermore, as shown in Figures 9 and 10, a tool-holding protrusion 34 is formed on the top of the barrel 3. The tool 32 is inserted into the tool-holding protrusion 34 through the insertion shaft 321, and the height of the tool-holding protrusion 34 is greater than or equal to the height of the insertion shaft 321. The tool-holding protrusion 34 limits the insertion shaft 321 of the tool 32, ensuring the stability of the tool 32 when it is inserted into the barrel 3. This prevents the tool 32 from accidentally falling off the top of the barrel 3 due to external force when the barrel 3 is not assembled into the housing, thus affecting the subsequent connection between the tool 32 and the output shaft 11.

[0036] The side wall of the cutter protrusion ring 34 is provided with a locking hole 341. When the connecting turntable 2 is in the assembly position 22, the cutter lock seat 312 is inserted into the locking hole 341 and abuts against the cutter 32. When the cutter 32 is re-locked, the locking element can be inserted into the cutter protrusion ring 34 through the locking hole 341 and re-lock the cutter 32, further ensuring the connection stability between the cutter 32 and the material cylinder 3.

[0037] Furthermore, as shown in Figures 8 and 9, a locking post 3122 is formed on the side of the locking knife seat 312 facing the locking knife protrusion ring 34. The cross-sectional area of ​​the locking post 3122 is smaller than the cross-sectional area of ​​the locking hole 341. A locking knife concave ring 322 is formed on the insertion shaft 321. The height of the locking knife concave ring 322 is greater than or equal to the height of the locking hole 341. A locking knife gap is formed between the inner wall surface of the locking knife concave ring 322 and the outer wall surface of the locking knife protrusion ring 34. The horizontal length of the locking post 3122 is greater than the locking knife gap. When the locking base 312 is reset, the locking base 312 can insert the locking pin 3122 into the locking hole 341 and move the locking pin 3122 toward the tool 32. Since the horizontal length of the locking pin 3122 is greater than the tool clamping distance, it can be ensured that when the locking pin 3122 clamps the tool 32, the wall surface of the locking base 312 forming the locking pin 3122 is located outside the outer wall surface of the tool clamping protrusion ring 34, thereby ensuring the clamping tightness and stability of the locking base 312 when clamping the tool 32 with the locking pin 3122.

[0038] In this embodiment, to facilitate suspending the material cylinder 3 in the connecting turntable 2, as shown in Figure 13, the bottom of the connecting turntable 2 has a connecting suspension groove 24 and an installation notch 25, and the side of the material cylinder 3 has an installation boss 35. When the connecting turntable 2 is in the assembly position 22, the installation boss 35 is aligned with the installation notch 25. When the connecting turntable 2 is in the fixed position 23, the installation boss 35 rotates and embeds into the suspension groove 24. Therefore, when connecting the material cylinder 3 and the connecting turntable 2, it is only necessary to align the installation boss 35 with the installation notch 25 of the connecting turntable 2, push the installation notch 25 of the material cylinder 3 upward into the installation notch 25, and then rotate the installation boss 35 toward the suspension groove 24 to complete the assembly action of the material cylinder 3 on the suspension turntable.

[0039] When the barrel 3 is suspended on the connecting turntable 2, the barrel 3 may reverse or move under the rotation of the output shaft 11 and the cutter 32. To prevent the barrel 3 from reversing and detaching from the connecting turntable 2, as an optional embodiment, as shown in Figures 3, 4 and 14, the connecting turntable 2 is provided with a stop pin 26, and the barrel 3 is formed with an anti-rotation boss 36. The anti-rotation boss 36 is formed with an anti-rotation surface 361 facing a preset direction, which is the direction of the suspension groove 24 facing the mounting notch 25. When the connecting turntable 2 is in the assembly position 22, the stop pin 26 is located above the anti-rotation boss 36. When the connecting turntable 2 is in the fixed position 23, the stop pin 26 abuts against the anti-rotation boss 36.

[0040] Understandably, when the cylinder 3 is suspended on the connecting turntable 2, the stop pin 26 is moved by force to the top of the anti-rotation boss 36 to prevent the stop pin 26 from obstructing the suspension action of the cylinder 3 on the connecting turntable 2. During the process of the mounting boss 35 moving to the suspension groove 24 and the connecting turntable 2 driving the cylinder 3 to move towards the fixed position 23, the stop pin 26 can move downwards relative to the anti-rotation surface 361 of the anti-rotation boss 36 and abut against the anti-rotation surface 361. Thus, the stop pin 26 can restrict the rotational freedom of the cylinder 3 in a preset direction, preventing the cylinder 3 from rotating back. This effectively prevents the cylinder 3 from reversing its direction or moving when the output shaft 11 and the cutter 32 drive the food inside the cylinder to rotate, preventing the cylinder 3 from detaching from the connecting turntable 2 and effectively ensuring the suspension stability of the cylinder 3 suspended on the connecting turntable 2.

[0041] Specifically, to ensure that the stop pin 26 can fall to the side of the anti-return surface after the cylinder 3 is suspended in the suspension groove 24, the suspension groove 24 has a preset groove width. When the connecting turntable 2 is located in the assembly position 22, a preset distance is formed between the stop pin 26 and the anti-rotation surface 361, and the preset groove width is greater than or equal to the preset distance. Therefore, during the process of the cylinder 3 rotating and being suspended in the suspension groove 24, the moving distance of the anti-rotation surface 361 is greater than the initial distance between the stop pin 26 and the anti-rotation surface 361. This ensures that during the process of the connecting turntable 2 moving towards the fixed position 23, the stop pin 26 can move downward relative to the anti-rotation surface 361 and fall to the side of the anti-rotation surface 361. This achieves the restriction of the rotational freedom of the cylinder 3 by the stop pin 26, correspondingly preventing the cylinder 3 from rotating back and ensuring the suspension stability of the cylinder 3.

[0042] In this embodiment, as shown in Figures 3, 4 and 11, the spiral guide portion 21 is an inclined guide groove 211 formed on the side of the connecting seat 12. The connecting turntable 2 is connected to the connecting seat 12 through the inclined guide groove 211, and the stop pin 26 is slidably connected to the inclined guide groove 211 to ensure that the stop pin 26 can slide with the connecting turntable 2 relative to the inclined guide groove 211, thereby realizing movement between the assembly position 22 and the fixed position 23.

[0043] To ensure that the stop pin 26 can move up and down relative to the anti-rotation surface 361 of the anti-rotation boss 36, a second elastic element (not shown in the figure) is provided between the stop pin 26 and the connecting turntable 2, and the fixed position 23 forms an unlocking groove 221. The side wall of the unlocking groove 221 is connected to the side wall of the inclined guide groove 211 by an arc, and the groove width of the unlocking groove 221 is greater than the groove width of the inclined guide groove 211. When the connecting turntable 2 is located at the fixed position 23, the stop pin 26 is located in the unlocking groove 221. The second elastic element is preferably a compression spring.

[0044] Understandably, during the process of the material cylinder 3 being suspended from the connecting turntable 2 and the connecting turntable 2 being moved from the assembly position 22 to the fixed position 23, the stop pin 26 can move from the unlocking groove 221 to the inclined guide groove 211. Since the width of the unlocking groove 221 is greater than the width of the inclined guide groove 211, the second elastic element compresses and stores energy under the pressing action of the inclined guide groove 211 on the stop pin 26. When the connecting turntable 2 moves from the fixed position 23 to the assembly position 22 and the stop pin 26 moves back to the unlocking groove 221, the stop pin 26 is no longer pressed by the inclined guide groove 211. At this time, under the reset action of the second elastic element, the stop pin 26 moves upward relative to the connecting turntable 2, thereby causing the stop pin 26 to move back above the anti-rotation surface 361 of the material cylinder 3, releasing the anti-rotation effect of the stop pin 26 on the material cylinder 3, thus facilitating the release of the assembly action between the material cylinder 3 and the machine body 1.

[0045] As an optional embodiment, as shown in Figures 3, 4 and 14, a limit switch 27 is slidably connected to the connecting turntable 2. When the connecting turntable 2 is in the fixed position 23, the anti-rotation boss 36 abuts against the limit switch 27. That is, when the material cylinder 3 is assembled and unlocked, the limit switch 27 is triggered. The limit switch 27 can be electrically connected to the drive structure (such as a drive motor) that drives the output shaft 11 in the machine body 1 to lift and rotate. Thus, the limit switch 27 can be triggered after the connecting turntable 2 drives the material cylinder 3 to move into place, thereby controlling the movement of the drive structure in the machine body 1, realizing the movement of the lifting shaft in the machine body 1, and completing the stirring and cutting action of the fruit puree machine on the food in the material cylinder 3.

[0046] Specifically, as shown in Figures 11 and 12, the connecting turntable 2 is formed with a vertical limiting groove 271, the limit switch 27 is slidably connected to the vertical limiting groove 271, a third elastic element (not shown in the figure) is arranged between the limit switch 27 and the vertical limiting groove 271, and the limit switch 27 is slidably connected to the inclined guide part. The fixed position 23 is formed with a trigger groove 231, and the groove width of the trigger groove 231 is smaller than the groove width of the inclined guide part.

[0047] Understandably, when the connecting turntable 2 moves the material cylinder 3 from the assembly position to the fixed position, the limit switch 27 can move synchronously to the fixed position along with the connecting turntable 2. Since the width of the trigger groove 231 in the fixed position 23 is smaller than the width of the inclined guide section, when the limit switch 27 moves to the fixed position 23, the trigger groove 231 can push the limit switch 27 downwards relative to the vertical limit groove 271, thereby bringing the limit switch 27 into contact with the limit boss and triggering the limit switch 27. Furthermore, by utilizing the cooperation between the trigger groove 231 and the limit switch 27, the synchronicity of movement between the limit switch 27 and the suspended turntable can be ensured, while also ensuring that the limit switch 27 is triggered only after the material cylinder 3 has moved into position. This further guarantees the operating sequence of the fruit pulp machine and avoids the problem of the drive structure starting before the material cylinder 3 is assembled.

[0048] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
