Description

Technical Field

[0001] The invention relates to the technical field of food processors, and in particular to a micro-fruit puree machine. Background Art

[0002] Prior art, such as Chinese utility model patent document, publication number CN222265103U, discloses a micro-puree machine and extrusion assembly, which uses a plunger connected to a master and slave shaft to push the processed ingredients out of a nozzle connected to a bowl. The plunger includes a seal around its periphery to ensure maximum contact with the wall of the bowl, thereby allowing maximum extrusion output.

[0003] In the prior art, there are two ways to combine the plunger and the driven shaft;

[0004] The first combination method is to install the tool and the plunger on the same bowl cover. In the normal state, the driven shaft is combined with the tool, and in the extrusion state, the driven shaft is combined with the plunger. The problem with this structure is that the driven shaft cannot be combined with the plunger, affecting the operation of the entire machine. Manual shutdown is required to reset the plunger and tool, which seriously affects normal use.

[0005] The second combination method is that the tool and the plunger are respectively arranged on the first cover and the second cover. After the tool completes the spinning and mixing, the bowl is removed and the bowl cover is replaced to replace the tool with the plunger. Although this method does not have the problem of combining the driven shaft and the plunger, it requires manual removal of the bowl and replacement of the bowl cover on the way. The process is too complicated and not practical, and needs further improvement. Summary of the invention

[0006] The present invention aims to solve at least one of the technical problems in the prior art. To this end, the present invention proposes a micro-fruit puree machine.

[0007] A micro-fruit puree machine designed for this purpose, the micro-fruit puree machine includes a fixed platform;

[0008] A bowl, the bowl is mounted on a fixed platform, the bowl is provided with a cavity for accommodating food, and the bowl is provided with an extrusion port communicated with the cavity;

[0009] An extrusion element is movably disposed in the cavity to force the food in the cavity to be extruded from the extrusion port;

[0010] The bowl is provided with an air passage interconnected with the cavity; the air inlet end of the air passage is connected to an air source, the air source supplies air to the air passage, and the air flow enters the cavity to push the extrusion element to move from the first position to the second position, so as to force the food in the cavity to be extruded from the extrusion port;

[0011] When the extrusion element is located at the first position, the extrusion element and the bowl member are coupled to each other to restrict the relative rotation of the two;

[0012] Mobile platform, the mobile platform is set to move relative to the fixed platform;

[0013] A cutting tool is rotatably connected to the moving platform, and the cutting tool extends into the cavity;

[0014] A mobile module, wherein the mobile module is configured to drive the mobile platform to move along a straight line relative to the fixed platform;

[0015] The driving module is arranged on the mobile platform and is transmission-connected with the mobile module and the tool.

[0016] Preferably, the mobile module comprises a screw rod rotatably arranged on the fixed platform, the mobile platform is rotatably provided with a screw nut, and the screw nut is threadedly connected to the screw rod;

[0017] The driving module is drivingly connected to the screw nut;

[0018] A brake module is arranged on the fixed platform, and the brake module is configured to apply rotation resistance to the screw rod to constrain the screw rod from rotating relative to the fixed platform.

[0019] Compared with the prior art, the pneumatically driven extrusion element adopted in the present invention not only does not need to consider the problem of the combination of the knife shaft and the extrusion element, but also does not need to disassemble the bowl during the food making process. While ensuring the normal operation of the machine, it can effectively reduce manual operation, improve the fluency of production, and meet the needs of users.

[0020] Compared with the prior art, the present invention has a brake module, when the brake module does not generate resistance to the screw rod, the screw rod and the screw nut rotate synchronously, so that the mobile platform remains suspended in one position, and at the same time, the tool, the screw rod and the screw nut rotate synchronously to achieve spinning and mixing. When the brake module generates resistance to the screw rod, the screw rod is constrained by the resistance, and the screw nut can move upward or downward relative to the screw rod as it rotates, so that the mobile platform drives the tool to move. In this solution, when the screw rod nut maintains the same rotation speed, as the screw rod is constrained by the resistance, the moving speed of the screw nut relative to the screw rod becomes faster, so as to change the displacement speed of the tool.

[0021] Compared with the prior art, the present invention has the advantages of preventing motor overload and stalling due to the rotation setting of the screw rod and the cooperation of the brake module. Since the motor needs to synchronously drive the tool to rotate and move during operation, when the tool is blocked and cannot move, that is, when the movement resistance of the tool is greater than the resistance applied by the brake module, the screw nut and the screw rod rotate synchronously, and the mobile platform does not move relative to the fixed platform, thereby achieving a state in which the tool only rotates but does not move, thereby ensuring the normal operation of the motor and avoiding damage to the motor and the transmission structure.

[0048] like Figures 1 to 18 As shown, the micro-fruit puree machine includes a fixed platform 10; a bowl 20, which is installed on the fixed platform 10, and the bowl 20 is provided with a cavity 201 for accommodating food, and the bowl 20 is provided with an extrusion port 240 interconnected with the cavity 201; an extrusion element 50, which is movably arranged in the cavity 201 to force the food in the cavity 201 to be extruded from the extrusion port 240; the bowl 20 is provided with an air channel 210 interconnected with the cavity 201; the air inlet end of the air channel 210 is connected to an air source, and the air source supplies air to the air channel 210, and the air flow enters the cavity 201 to push the extrusion element 50 to move from the first position 202 to the second position The device is provided with a housing 203 to force the food in the cavity 201 to be squeezed out from the extrusion port 240; when the extrusion element 50 is in the first position, the extrusion element 50 and the bowl 20 are coupled to each other to restrict the relative rotation of the two; the mobile platform 30, the mobile platform 30 is movably arranged relative to the fixed platform 10; the tool 60, the tool 60 is rotatably connected to the mobile platform 30, and the tool 60 extends into the cavity 201; the mobile module 70, the mobile module 70 is configured to drive the mobile platform 30 to move in a straight line relative to the fixed platform 10; the driving module 40, the driving module 40 is arranged on the mobile platform 30 and is transmission-connected to the mobile module 70 and the tool 60.

[0049] When in use, the user installs the bowl 20 containing food on the fixed platform 10. The micro-fruit puree machine can perform a spinning mode and an extrusion mode in the working mode;

[0050] In the whirling mode, the driving module synchronously drives the cutter 60 and the moving module 70, and the moving module 70 drives the moving platform 30 to move in a straight line relative to the fixed platform 10, and the moving direction is from the second position 203 to the first position 202, and then resets from the first position 202 to the second position 203, and drives the cutter 60 to rotate. In this mode, the cutter 60 can rotate and move synchronously to whirl and mix the food in the bowl 20.

[0051] In the extrusion mode, under the action of the air source, the airflow drives the extrusion element 50 to move from the first position 202 to the second position 203 to force the food in the cavity 201 to be extruded from the extrusion port 240 .

[0052] During use, the airflow drives the extrusion element 50 to move from the first position 202 to the second position 203 to complete the extrusion of food. Regarding the reset of the extrusion element 50, the extrusion element 50 is reset manually, that is, after the extrusion of food is completed, the bowl 20 is removed from the fixed platform 10, and the bowl 20 and the extrusion element 50 are cleaned, and then the extrusion element 50 is installed in the cavity 201 and driven to move to the first position 202, that is, the reset is completed.

[0053] In the spinning mode, when the cutter 60 moves to the second position 203, the cutter 60 will be pressed against the surface of the extrusion element 50 as it moves. This step is to prevent the entire bowl 20 from freezing along with the food and preventing the extrusion element 50 from being unable to loosen. The cutter 60 presses against the extrusion element 50 to slightly displace the extrusion element 50 relative to the bowl 20, so that the frost between the extrusion element 50 and the bowl 20 breaks, ensuring that the extrusion element 50 can move relative to the bowl 20, thereby achieving the extrusion of food from the extrusion port 240.

[0054] like Figure 4 As shown, in this figure, the micro-fruit puree machine is in use, and the extrusion port 240 is set downward to enable the extrusion element to force the food located in the cavity 201 to be squeezed out from the extrusion port 240, and the food is squeezed downward to facilitate the user to collect it below the extrusion port 240.

[0055] like Figure 1 As shown, the fixed platform 10 is provided with a plurality of guide pillars 100 , and the mobile platform 30 is slidably connected to the guide pillars 100 to ensure the stability of the mobile platform 30 moving relative to the fixed platform 10 .

[0056] The cavity 201 is a chamber with a columnar structure, and the extrusion element 50 is a disc structure, and the two cooperate with each other to enable the extrusion element 50 to move in the cavity 201 .

[0057] like Figures 2 to 4As shown in the figure, the moving module 70 includes a lead screw 710 rotatably arranged on the fixed platform 10. A lead screw nut 720 is rotatably arranged on the moving platform 30, and the lead screw nut 720 is in threaded connection with the lead screw 710. The driving module 40 is in transmission connection with the lead screw nut 720. A braking module 80 is arranged on the fixed platform 10, and the braking module 80 is configured to apply a rotational resistance to the lead screw 710 to restrict the rotation of the lead screw 710 relative to the fixed platform 10. In this embodiment, the lead screw 710 is different from the lead screw in the existing linear transmission of the lead screw. Here, the lead screw 710 is rotatably arranged. When the braking module does not generate resistance to the lead screw, the lead screw and the lead screw nut rotate synchronously to keep the moving platform hovering at any position. At the same time, the tool rotates, so that the tool hovers at any position for rotary beating. However, when the braking module generates resistance to the lead screw, the lead screw is restricted by the resistance, and the lead screw nut can move up or down relative to the lead screw as it rotates, so that the moving platform drives the tool to displace. In this solution, when the lead screw nut maintains the same rotational speed, the greater the resistance to which the lead screw is subjected, the faster the moving speed of the lead screw nut relative to the lead screw, so as to change the displacement speed of the tool. Thus, under the action of the braking module 80, this micro puree machine can, under the action of a single driving module, while the tool 60 rotates continuously, control whether the tool 60 moves and the speed of its movement, so as to adjust the movement of the tool 60 according to specific foods, thereby making food with a better taste to meet the needs of users.

[0058] As Figures 2 to 4 shown in the figure, the driving module 40 includes a driving motor 410 arranged on the moving platform 30. A first gear 420 is connected to the motor shaft of the driving motor 410. A second gear 430 is connected to the lead screw nut 720, and the second gear 430 is in transmission connection with the tool 60. The first gear 420 and the second gear 430 are meshed with each other.

[0059] The lead screw nut 720 and the second gear 430 are of an integral structure.

[0060] As Figure 2 shown in the figure, the tool 60 includes a tool shaft 610. One end of the tool shaft 610 is rotatably connected to the moving platform 30, and the other end is provided with a tool disc 620. The tool disc 620 is provided with first cutting teeth 630 for rotary beating food. The driving module 40 is rotatably connected to the tool shaft 610. During the rotation of the tool disc 620, the first cutting teeth 630 come into contact with the food located in the cavity 201 to achieve rotary beating and mixing. As the moving platform 30 displaces, it drives the tool disc 620 to move, thereby changing the position to achieve rotary beating and mixing at different positions.

[0061] As Figures 2 to 4As shown, a coupling 450 is rotatably provided on the mobile platform 30 , the knife shaft 610 is connected to the coupling 450 , and the coupling 450 is provided with a third gear 440 , and the third gear 440 and the second gear 430 are meshed with each other.

[0062] The knife shaft 610 is connected to the coupling 450, and the two can be connected using existing connection structures, such as a screw connection, a threaded connection, or other existing connection structures.

[0063] like Figure 3 and Figure 5 As shown, the peripheral wall of the blade disc 620 is provided with second blade teeth 640, and the second blade teeth 640 are extended along the radial direction of the blade disc 620; the first blade teeth 630 are extended along the axial direction of the blade shaft 610. The function of the second blade teeth 640 is to clean the food adhering to the peripheral wall of the cavity 201, and prevent the food from freezing on the peripheral wall of the cavity 201 and affecting the movement of the extrusion element 50. During the movement and spinning process of the blade disc 620, the second blade teeth 640 extending along the radial direction of the blade disc 620 can crush the food located on the peripheral wall of the cavity 201, thereby ensuring that the extrusion element 50 can move in close contact with the peripheral wall of the cavity 201.

[0064] A plurality of second blade teeth are arranged on the blade disc along a circumference.

[0065] like Figure 3 and Figure 6 As shown, the bowl 20 is connected to the bowl cover 220 , and the extrusion port 240 is arranged on the bowl cover 220 .

[0066] like Figure 6 and Figure 7 As shown, the bowl 20 is opened on the upper side, and the bowl cover 220 is arranged on the upper side of the bowl 20. Under the action of the airflow, the extrusion element 50 moves from the first position 202 to the second position 203, that is, moves from bottom to top, so as to drive the food to move from bottom to top until it is extruded from the extrusion port 240.

[0067] like Figure 3 and Figure 6 As shown, the bowl cover 220 is installed on the fixed platform 10, and the bowl member 20 and the bowl cover 220 are detachably connected, and the two can be connected by a threaded structure or a screw-on structure.

[0068] The bowl cover 220 is provided with an axial hole 222 , and the knife shaft 610 passes through the axial hole 222 and extends into the cavity 201 inside the bowl 20 . The knife shaft 610 can be movably arranged relative to the axial hole 222 .

[0069] The bowl cover 220 is provided with a screw-on structure 221 , which is screw-on connected to the fixed platform 10 .

[0070] like Figure 8As shown, the bowl cover 220 is provided with an air inlet 230, and the air inlet 230 is interconnected with the air passage 210. The advantage of setting the air inlet 230 on the bowl cover 220 is that since the air source needs to be set on the fixed platform 10, each time the bowl 20 is disassembled, the connection of the air source does not affect the disassembly of the bowl 20, which is convenient for operation.

[0071] like Figure 7 and Fig.10 As shown, the bowl 20 is provided with an air inlet 280, and a connecting air cavity 270 is provided between the bowl cover 220 and the bowl 20; the air inlet hole 230, the connecting air cavity 270, the air inlet 280 and the air passage 210 are connected in sequence.

[0072] like Figure 6 As shown, the outer wall of the bowl 20 is provided with a boss 204, and a sealing rubber ring 290 is provided on the boss 204. When the bowl cover 220 and the bowl 20 are connected, the convex ring 223 of the bowl cover 220 abuts against the sealing rubber ring 290, and the bowl cover 220, the sealing rubber ring 290 and the bowl 20 are surrounded to form a communicating air cavity 270. That is, when the bowl cover 220 and the bowl 20 are connected, the communicating air cavity 270 is automatically formed.

[0073] When the extrusion element 50 is assembled to the first position 202, there is an air gap between the extrusion element 50 and the bottom wall of the cavity 201, and the airflow enters the air gap through the air channel 210. The airflow in the air gap pushes the entire extrusion element 50 to move relative to the bowl 20. The air gap can make the airflow entering evenly distributed to ensure the stability of pushing the extrusion element.

[0074] An air source is provided on the fixed platform 10, and the air source is connected to the air inlet 230 by a pipe. The air source adopts an air pump, and the specifications of the air pump are selected according to the required thrust, so that the airflow pushes the extrusion element 50 to move. The air pump outputs airflow, and the airflow is connected in sequence through the pipe, the air inlet 230, the connecting air cavity 270, the air inlet 280 and the air channel 210.

[0075] See also Figure 6 The bowl cover 220 is provided with a material port 250 which is interconnected with the cavity 201. The function of the material port 250 is that after the food is swirled and mixed, the material port 250 can add fluid material into the cavity 201 under the action of the material pump, so that the newly added material can be mixed with the swirled and mixed food.

[0076] The material port 250 and the extrusion port 240 are respectively provided with valve bodies. The valve body is a one-way valve body. When the valve body is applied to the material port 250, the valve body is opened in one direction to allow the external material to enter the cavity 201 through the material port 250. At the same time, when the valve body is applied to the extrusion port 240, the valve body is opened in one direction to allow the food in the cavity 201 to be output to the outside through the extrusion port 240 under the action of the extrusion element.

[0077] like Figure 3 and Figure 5 As shown, the extrusion element 50 is provided with a first coupling portion 510, and the bottom wall of the cavity 201 is provided with a second coupling portion 260; the first coupling portion 510 and the second coupling portion 260 are plugged and matched with each other to constrain the extrusion element 50 and the bowl 20 to rotate relative to each other. When making food, it is necessary to first install the extrusion element 50 into the cavity 201 and fit it with the bottom wall of the cavity 201, and make the first coupling portion 510 and the second coupling portion 260 plug and match with each other. After the matching is completed, the extrusion element 50 and the bowl 20 can be constrained, and the extrusion element 50 is constrained so that when it is located at the first position 202, it cannot rotate relative to the bowl 20. This prevents the food frozen on the extrusion element 50 from rotating due to the rotation of the extrusion element 50 when the cutter 60 is spinning. It can ensure that the cutter 60 is spinning normally, and prevent the food from rotating with the cutter 60 and being unable to be spun.

[0078] like Figure 7 As shown, the bottom wall of the cavity 201 is provided with a connecting hole 200, which is connected with the cavity 201 and the airway 210. The connecting hole 200 serves as a connecting function, allowing the airflow inside the airway 210 to smoothly enter the cavity 201.

[0079] The communicating hole 200 is a non-circular hole, and the extruding element 50 is provided with a third coupling portion 500, the shape of the third coupling portion 500 is consistent with the shape of the communicating hole 200, and the third coupling portion 500 is movably plugged into the communicating hole 200. The non-circular hole is provided so that after the third coupling portion 500 and the communicating hole 200 are plugged and matched, the extruding element 50 can be constrained to rotate relative to the bowl 20.

[0080] The extrusion element 50 is in close contact with the peripheral wall of the cavity 201 . The purpose of the close contact is to ensure the sealing property so that the airflow input from the airway acts on the extrusion element 50 to push the extrusion element 50 to move.

[0081] like Figure 2 and Figure 3 As shown, a sealing ring 520 is provided on the wall surface where the extrusion element 50 and the peripheral wall of the cavity 201 are in contact, and the sealing ring 520 is in contact with the peripheral wall of the cavity 201. The function of the sealing ring 520 is to strengthen the sealing performance between the extrusion element 50 and the peripheral wall of the cavity 201 to prevent air leakage from affecting the thrust of the airflow pushing the extrusion element 50.

[0082] like Fig.12As shown, the extrusion element 50 is provided with an annular cutter 530, which is in contact with the peripheral wall of the cavity 201, and the annular cutter 530 is extended from the first position 202 to the second position 203. The purpose of the annular cutter 530 is to clean the food on the peripheral wall of the cavity 201, especially some smoothie particles remaining on the peripheral wall, so as to prevent them from affecting the movement of the extrusion element 50.

[0083] like Fig.16 As shown, the first embodiment of the brake module 80 includes a brake rotor 810 fixedly arranged on the screw 710, and a friction element 820 is movably arranged on the fixed platform 10; when the friction element 820 contacts the brake rotor 810, the rotational resistance to the screw 710 is increased by generating friction force, so as to constrain the screw 710 to rotate relative to the fixed platform 10. In this embodiment, the effect achieved is that under the action of contact friction, the rotational resistance to the screw 710 is increased, and the greater the friction force, the greater the rotational resistance to the screw, and when the driving motor 410 is maintained at the same speed, the linear movement speed of the screw nut 720 relative to the screw 710 is faster. On the contrary, when the friction force is smaller, the rotational resistance to the screw 710 is smaller, and the linear movement speed of the screw nut 720 relative to the screw 710 is slower.

[0084] like Fig.16 As shown, the friction element 820 is in a semicircular structure, one end of the friction element 820 is rotatably arranged on the fixed platform 10, the other end of the friction element 820 is rotatably connected to a first pull rod 824, a first speed regulating knob 823 is rotatably arranged on the fixed platform 10, and the first pull rod 824 is rotatably connected to the first speed regulating knob 823. Under the rotation of the first speed regulating knob 823, the first pull rod 824 drives the friction element 820 to rotate around the first main axis 822, so that as the first speed regulating knob 823 rotates forward or reversely, the friction element 820 gradually approaches the brake rotor 810 or gradually moves away from the brake rotor 810.

[0085] The first speed regulating knob 823 can be rotatably arranged on the fixed platform 10 by using a rotary damper, so as to prevent the first speed regulating knob 823 from rotating under other external forces, thereby changing the friction coefficient between the friction element 820 and the brake rotor 810 and affecting the moving speed of the screw nut 720 .

[0086] like Fig.16 As shown, a friction plate 821 is arranged on the wall surface of the friction element 820 facing the brake rotor 810. The arrangement of the friction plate 821 can improve the wear resistance so that it will not be easily damaged during long-term contact friction.

[0087] like Fig.17As shown, the second embodiment of the brake module 80 includes a brake rotor 810, a fixed magnetic ring frame 831 and a movable magnetic ring frame 832, wherein the fixed magnetic ring frame 831 and the movable magnetic ring frame 832 are provided with permanent magnets; the fixed magnetic ring frame 831 and the movable magnetic ring frame 832 are combined to form a magnetic ring, and the brake rotor 810 is arranged in the magnetic ring and is fixedly connected to the screw 710; the fixed magnetic ring frame 831 is fixedly arranged on the fixed platform 10, and the movable magnetic ring frame 832 is movable relative to the fixed platform 10; when the movable magnetic ring frame 832 approaches or moves away from the brake rotor 810, the magnetic field strength is changed, thereby changing the rotation resistance of the screw 710. As the movable magnetic ring frame 832 moves relative to the fixed platform 10, when it gradually moves away from the brake rotor 810, the magnetic field strength is gradually weakened, and the rotation resistance to the screw 710 is gradually reduced, thereby reducing the moving speed of the screw nut 720. On the contrary, when the movable magnetic ring frame 832 gradually approaches the brake rotor 810 , the magnetic field strength gradually increases, and the rotational resistance to the screw rod 710 gradually increases, thereby increasing the moving speed of the screw rod nut 720 .

[0088] like Fig.17 As shown, one end of the movable magnetic ring frame 832 is rotatably connected to the fixed platform 10, and the other end of the movable magnetic ring frame 832 is provided with a second pull rod 835. A second speed regulating knob 834 is rotatably provided on the fixed platform 10, and the second pull rod 835 is rotatably connected to the second speed regulating knob 834. Under the rotation of the second speed regulating knob 834, the second pull rod 835 drives the movable magnetic ring frame 832 to rotate around the second main axis 833, so that as the second speed regulating knob 834 rotates forward or reversely, the movable magnetic ring frame 832 gradually approaches the brake rotor 810 or gradually moves away from the brake rotor 810.

[0089] The second speed regulating knob 834 can be rotatably arranged on the fixed platform 10 by using a rotary damper, so as to avoid the second speed regulating knob 834 rotating under other external forces, thereby preventing the distance between the moving magnetic ring frame 832 and the brake rotor 810 from changing and affecting the moving speed of the screw nut 720 .

[0090] like Fig.18 As shown, the third embodiment of the brake module 80 includes a stator pole 860, the stator pole 860 is connected to a fixed ring 850, a coil 840 is arranged in the fixed ring 850, a brake rotor 810 is arranged between the fixed ring 850 and the stator pole 860, and the brake rotor 810 is fixedly connected to the screw rod 710. In this embodiment, the principle of the brake module 80 is the same as that of the existing hysteresis brake, which is to change the excitation current of the coil 840 by energizing the coil 840, thereby adjusting the magnetic field strength to control the torque of the brake rotor 810, so as to change the rotation resistance of the screw rod 710, thereby constraining the screw rod 710 to rotate.
