Description

Technical Field

[0001] The present application belongs to the technical field of household appliances, and in particular, relates to a household meat grinder. Background Art

[0002] When people cook, they often need to cut meat into minced meat. It is very laborious to cut with a knife, and it is not convenient to mince more meat. Usually, a meat grinder is used to mince the meat. The existing meat grinders are bulky, have high production costs, are inconvenient to move, and are not easy to be popularized by ordinary families.

[0003] An existing foreign patent with publication number ES2718197T3 discloses a household appliance for cooking preparation, including a driver rotatably driven by a motor and a working tool, the working tool including a bushing detachably engaged on the driver, including a portion of the driver having at least one drive ramp, which cooperates with a complementary drive ramp carried by the bushing to handle the tool workpiece, the drive ramp having a certain inclination so that the rotation of the driver in the direction of rotation of the motor generates a force on the bushing, thereby keeping it in a crimped state on the driver, and also including at least one retaining surface of the driver in contact with a stop member, the stop member being carried by the working tool in the driver.

[0004] Although the above-mentioned chopper can realize the function of mincing meat, a general meat grinder will cut the meat into minced meat through repeated cutting for many times. However, different mincing speeds need to be selected according to the different states of the meat. Some meat pieces may be hard due to being frozen and not completely thawed, and are suitable for low-speed mincing of the blade. As the meat is minced, the meat will become soft and have a certain viscosity, and the resistance will be greater, which is suitable for high-speed mincing of the blade. However, the existing meat grinders often have a constant blade speed for mincing meat, and the adaptive adjustment of the blade speed cannot be achieved. Improvements are needed in this regard. Summary of the invention

[0005] The purpose of the present application is to provide a household meat grinder in order to solve the above-mentioned technical problems. The meat grinder can grind frozen meat before it is completely thawed. The meat is slowly ground at an initial low speed. As the state of the ground meat changes, the rotation speed of the meat grinder blade is gradually increased to improve the stability of the meat grind and ensure the uniformity of the size of the meat froth after the meat is ground.

[0006] The present application provides a household meat grinder, comprising:

[0007] The container body is provided with a cover body;

[0008] A blade assembly, comprising a blade body and a rotating shaft, wherein the blade assembly cuts meat when rotating;

[0009] A driving device, used for driving the blade assembly to rotate, the driving device comprising a driving housing and a driving motor;

[0010] An adjusting transmission mechanism is installed in the driving housing, and the adjusting transmission mechanism is used to control the rotation speed of the blade assembly;

[0011] Among them, the cover body is provided with a through hole, the end of the rotating shaft passes through the through hole, the driving device is provided with a rotating seat, the rotating seat is movably connected to the driving shell, the rotating seat corresponds to the rotating shaft, the rotating seat is connected to the adjusting transmission mechanism, and the rotating seat is provided with a detection mechanism.

[0012] The container is used to hold meat chunks. The installation steps before mincing meat are as follows: fit the blade assembly into the container, then put the meat chunks in, cover the cover, pass the rotating shaft through the through hole of the cover, install the driving device on the cover and ensure that the rotating shaft of the blade assembly is connected to the rotating seat, drive the rotating seat and the rotating shaft to rotate through the driving motor, and the blade rotates to chop the meat chunks. The rotating speed of the rotating seat and the rotating shaft is changed by adjusting the transmission mechanism. As the meat chunks are continuously chopped, the contact area between the meat chunks increases, and the contact area between the meat chunks and the blade body increases, resulting in an increase in resistance when the blade body rotates. To ensure the chopping effect of the blade body on the meat chunks, when the detection mechanism detects an increase in resistance, the transmission mechanism is controlled to change the rotating speed of the rotating seat and the rotating shaft to improve the chopping effect of the blade body. The frozen meat chunks are minced when they are not completely thawed. The initial low-speed rotation of the blade assembly can appropriately reduce the vibration during the initial mincing, making the mincing process more stable.

[0013] Furthermore, the adjusting transmission mechanism comprises:

[0014] An active roller connected to the driving device, wherein the active roller comprises an active fixed cone disk and an active movable cone disk;

[0015] A driven roller connected to the rotating seat, wherein the driven roller comprises a driven fixed cone disc and a driven movable cone disc;

[0016] The transmission belt is placed between the driving roller and the driven roller;

[0017] A movable frame is movably connected with the active movable cone disc and the driven movable cone disc;

[0018] A first transmission shaft connected between the driven roller and the rotating seat;

[0019] Wherein, the movable frame is provided with a pushing part.

[0020] The adjusting transmission mechanism adjusts the rotation speed of the rotating seat by changing the transmission radius ratio between the active roller and the driven roller. The transmission belt is wound between the active roller and the driven roller. The movable frame and the active movable cone disk and the driven movable cone disk are movably connected through bearings or bearing shells. When the movable frame moves by pushing the pushing part, the active movable cone disk and the driven movable cone disk move along the axial direction of the first transmission shaft, the radius ratio between the active roller and the driven roller is changed to achieve speed adjustment. The first transmission shaft is installed and connected with the driven roller to ensure that the first transmission shaft and the driven roller rotate at the same time.

[0021] Furthermore, the driving device further comprises:

[0022] A driving gear, mounted and connected to a driving motor;

[0023] A transmission gear, corresponding to the driving gear;

[0024] The second transmission shaft is connected between the transmission gear and the driving roller.

[0025] The driving gear is installed on the output shaft of the driving motor, the driving gear is meshed with the transmission gear, the transmission gear is connected to the active roller through the second transmission shaft, and the driving motor is used to drive the active roller to rotate.

[0026] Furthermore, the detection mechanism includes:

[0027] A clamping block is placed on a rotating seat;

[0028] A telescopic column mounted on the clamping block;

[0029] Telescopic slot, corresponding to the telescopic column;

[0030] The electrical connectors are respectively disposed at the end of the telescopic column and the bottom of the telescopic slot and correspond to each other;

[0031] A micro motor is installed in the rotating seat, and the micro motor is provided with a first threaded rod;

[0032] An internal thread seat connected to the first threaded rod, wherein the internal thread seat is provided with a push plate;

[0033] Among them, the rotating shaft is provided with a limiting part, the rotating seat is provided with a limiting groove corresponding to the limiting part, guide inclined surfaces are provided on both sides of the limiting groove, the clamping block is movably installed on the side wall of the limiting groove, the clamping block is provided with a pushing groove, the push plate is placed in the pushing groove and extends outward to be connected with the internal threaded seat, and first springs are provided on both sides of the push plate to resist the pushing groove.

[0034] When the rotating shaft is installed and connected with the rotating seat, the limiting part is placed in the limiting groove, and the guiding inclined surface is used to guide the limiting part into the limiting groove when the rotating shaft and the rotating seat are matched. The first spring acts on the pushing groove, and the pushing groove and the clamping block are installed into an integrated structure. The limiting part is clamped in the limiting groove by the clamping block to improve the stability between the rotating shaft and the rotating seat. With the resistance received during the rotation of the blade assembly, the clamping block is acted on the clamping block through the limiting part to make the clamping block retract and move inward. The telescopic column is installed and connected with the clamping block. When the clamping block moves, the telescopic column and the clamping block are retracted. The column is placed in the telescopic slot and moves. When the telescopic column abuts against the bottom of the telescopic slot, the two corresponding electrical connectors abut against each other, thereby enabling the micro-motor to be energized. The first threaded rod is driven to rotate by the micro-motor, and the threaded pair connection between the first threaded rod and the internal threaded seat is used to push the internal threaded seat and the push plate to move. The first spring abuts against the push plate and the push slot. When the push plate moves, the force of the first spring on the clamping block is changed, so that the detection threshold of the detection mechanism rises simultaneously with the increase of the resistance received by the rotation of the blade assembly, and the clamping effect of the low limit part is guaranteed by the first spring.

[0035] Furthermore, the rotating seat comprises:

[0036] An adjusting block is installed and connected with the internal thread seat, and the adjusting block is provided with a first sliding groove;

[0037] A movable seat, movably connected to the first transmission shaft;

[0038] An abutment plate, movably connected to the movable seat;

[0039] Among them, the movable seat is provided with a sliding column corresponding to the first sliding groove, and the rotating seat is provided with a second sliding groove corresponding to the sliding column. The moving direction of the second sliding groove limiting the sliding column is the same as the axis of the first transmission shaft. The angle between the first sliding groove and the second sliding groove is 20°-80°, and the abutment plate and the pushing part are connected by a plurality of groups of folding parts.

[0040] As the resistance to the rotation of the blade assembly increases, the detection threshold of the detection mechanism rises, and the rotation speed of the blade assembly is increased. The adjustment block is installed and connected to the internal thread seat and moves at the same time. The movable seat is connected to the first slide groove on the adjustment block and the second slide groove on the rotating seat through a slide column. The second slide groove limits the movable seat to move along the axial direction of the first transmission shaft. The first slide groove and the second slide groove form an angle of 20°-80°. When the adjustment block moves, the movable seat is pushed to move along the axial direction of the first transmission shaft through the first slide groove. The smaller the angle between the first slide groove and the second slide groove, the faster the moving speed of the movable seat is, and the faster the adjustment speed is. The larger the angle, the slower the moving speed of the movable seat is, and the slower the adjustment speed is. The abutment plate and the movable seat are connected by connecting members such as bearings or bearing shells. The first transmission shaft, the rotating seat, and the movable seat rotate simultaneously. The abutment plate and the pushing part are connected by a folding member to improve the stability of the abutment plate and the movable seat when they move. When the abutment plate pushes the pushing part to move, the change of the transmission radius ratio between the active roller and the driven roller is realized, and the rotation speed of the rotating seat is adjusted.

[0041] Furthermore, the movable frame comprises:

[0042] A limit plate is movably mounted in the driving housing, the limit plate is placed below the movable frame, and the limit plate is used to control the initial rotation speed of the blade assembly;

[0043] A control frame connected to the abutment plate;

[0044] A second spring is placed between the control frame and the movable frame;

[0045] Wherein, the movable frame is movably connected to the control frame.

[0046] Before the meat grinder grinds meat, the movable frame is moved by adjusting the position of the limit plate to control the initial rotation speed of the blade assembly. The control frame is installed and connected with the abutment plate. When the control frame moves toward the movable frame, the second spring is used to stabilize the structure between the pushing part of the movable frame and the control frame.

[0047] Furthermore, the driving device further comprises:

[0048] An adjustment button is movably mounted on the drive housing;

[0049] A worm screw, mounted and connected with the adjusting button;

[0050] Worm wheel, corresponding to the worm;

[0051] The second threaded rod is installed and connected with the worm gear, and the second threaded rod is connected with the limiting plate.

[0052] The worm is controlled to rotate by turning the adjustment button. The worm cooperates with the worm wheel. When the worm rotates, the worm wheel rotates. The second threaded rod is connected to the worm wheel. The rotation of the second threaded rod is controlled by the worm wheel. The second threaded rod is connected to the limiting part by a threaded pair to realize the position adjustment of the limiting plate.

[0053] Furthermore, the specific control method includes:

[0054] S1, placing the meat in the container, covering the cover, installing the driving device, turning the adjustment button to the required initial adjustment speed, and starting the driving device;

[0055] S2, the blade assembly rotates at a low speed. Before the abutment plate abuts against the movable frame, the blade assembly rotates at the initial speed V0 set by the adjustment button. As the blade assembly chops the meat, the abutment plate abuts against the movable frame through the movement of the adjustment block. As the adjustment block continues to move, the abutment plate pushes the movable frame to move, and the speed of the blade assembly is increased;

[0056] S3, when the mincing is completed, the driving device is turned off, and the micro motor drives the internal thread seat to reset.

[0057] When the blade assembly is started, it first rotates at a low speed. Then the resistance received by the blade when it rotates increases, and this is fed back to the detection mechanism. The transmission mechanism is adjusted to adaptively adjust the resistance received, thereby reducing the energy consumption of the drive motor when starting. At the same time, the vibration in the initial state of minced meat is reduced, making the meat grinder more stable when mincing meat. As the speed of the blade assembly increases, the final effect of the blade assembly on minced meat is guaranteed.

[0058] The beneficial effects of this application are:

[0059] 1. When the frozen meat is minced before it is completely thawed, the initial low-speed rotation of the blade assembly can appropriately reduce the vibration during the initial mincing, making the mincing process more stable. The rotation speed of the rotating seat and the rotating shaft is changed by adjusting the transmission mechanism. As the meat is continuously minced, the contact area between the meat pieces increases, and the contact area between the meat pieces and the blade body increases, resulting in an increase in the resistance of the blade body when it rotates, in order to ensure the mincing effect of the blade body on the meat pieces.

[0060] 2. When the detection mechanism detects that the resistance increases, the transmission mechanism is controlled and adjusted to change the rotation speed of the rotating seat and the rotating shaft to improve the chopping effect of the blade body.

[0061] 3. The transmission mechanism is adjusted by changing the transmission radius ratio between the active roller and the driven roller to adjust the rotation speed of the rotating seat. The transmission belt is wound between the active roller and the driven roller, and the stability of the transmission belt during transmission is improved by the limit wheel.

[0062] 4. The adjusting block is installed and connected to the internal thread seat and moves simultaneously. The movable seat is connected to the first sliding groove on the adjusting block and the second sliding groove on the rotating seat through the sliding column. The second sliding groove limits the movable seat from moving along the axial direction of the first transmission shaft. BRIEF DESCRIPTION OF THE DRAWINGS

For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0073] The following provides a detailed description of the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0074] Embodiment 1:

[0075] like Figure 1-Figure 6 As shown, the embodiment of the present application provides a household meat grinder, comprising:

[0076] The container 100 is provided with a cover 110;

[0077] The blade assembly 200 includes a blade body 210 and a rotating shaft 220, and the blade assembly 200 chops meat when rotating;

[0078] A driving device 300 is used to drive the blade assembly 200 to rotate, and the driving device 300 includes a driving housing 310 and a driving motor 320;

[0079] An adjusting transmission mechanism 400 is installed in the driving housing 310, and the adjusting transmission mechanism 400 is used to control the rotation speed of the blade assembly 200;

[0080] Among them, the cover body 110 is provided with a through hole 111, the end of the rotating shaft 220 passes through the through hole 111, the driving device 300 is provided with a rotating seat 330, the rotating seat 330 is movably connected with the driving shell 310, the rotating seat 330 corresponds to the rotating shaft 220, the rotating seat 330 is connected with the adjusting transmission mechanism 400, and the rotating seat 330 is provided with a detection mechanism 500.

[0081] The container 100 is used to contain meat chunks. The installation steps before mincing meat are as follows: fit the blade assembly 200 into the container 100, then put the meat chunks in, cover the cover 110, make the rotating shaft 220 pass through the through hole 111 of the cover 110, install the driving device 300 on the cover 110 and ensure that the rotating shaft 220 of the blade assembly 200 is connected to the rotating seat 330, drive the rotating seat 330 and the rotating shaft 220 to rotate by the driving motor 320, and the blades rotate to chop the meat chunks. The rotating speed of the rotating seat 330 and the rotating shaft 220 is changed by adjusting the transmission mechanism 400, and the meat chunks are chopped. The continuous chopping of meat blocks increases the contact area between the meat blocks and the contact area between the meat blocks and the blade body 210, resulting in an increase in the resistance when the blade body 210 rotates. In order to ensure the chopping effect of the blade body 210 on the meat blocks, when the detection mechanism 500 detects an increase in resistance, the control and adjustment transmission mechanism 400 changes the rotation speed of the rotating seat 330 and the rotating shaft 220 to improve the chopping effect of the blade body 210. The frozen meat blocks are minced when they are not completely thawed. The initial low-speed rotation of the blade assembly 200 can appropriately reduce the vibration during the initial mincing, making the mincing process more stable.

[0082] Embodiment 2:

[0083] like Figure 4 , Figure 5 As shown, the embodiment of the present application provides a household meat grinder. In addition to the above technical features, the adjustment transmission mechanism 400 further includes:

[0084] The active roller 410 is connected to the driving device 300, and the active roller 410 includes an active fixed cone disk 411 and an active movable cone disk 412;

[0085] A driven roller 420 connected to the rotating seat 330, wherein the driven roller 420 includes a driven fixed cone disc 421 and a driven movable cone disc 422;

[0086] The transmission belt 430 is placed between the driving roller 410 and the driven roller 420;

[0087] The movable frame 440 is movably connected to the active movable cone disc 412 and the driven movable cone disc 422;

[0088] The first transmission shaft 450 is connected between the driven roller 420 and the rotating seat 330;

[0089] The movable frame 440 is provided with a pushing portion 441 .

[0090] The adjustment transmission mechanism 400 adjusts the rotation speed of the rotating seat 330 by changing the transmission radius ratio between the active roller 410 and the driven roller 420. The transmission belt 430 is wound between the active roller 410 and the driven roller 420. The movable frame 440 and the active movable cone disk 412 and the driven movable cone disk 422 are movably connected through bearings or bearing shells. When the movable frame 440 moves by pushing the pushing part 441, the active movable cone disk 412 and the driven movable cone disk 422 are moved along the axial direction of the first transmission shaft 450, the radius ratio between the active roller 410 and the driven roller 420 is changed to achieve speed adjustment. The first transmission shaft 450 and the driven roller 420 are installed and connected to ensure that the first transmission shaft 450 and the driven roller 420 rotate at the same time.

[0091] Embodiment 3:

[0092] like Figure 2 As shown, the embodiment of the present application provides a household meat grinder. In addition to the above technical features, the driving device 300 further includes:

[0093] A driving gear 340 is installed and connected to the driving motor 320;

[0094] A transmission gear 350 corresponding to the driving gear 340;

[0095] The second transmission shaft 360 is connected between the transmission gear 350 and the driving roller 410 .

[0096] The driving gear 340 is mounted on the output shaft of the driving motor 320 . The driving gear 340 meshes with the transmission gear 350 . The transmission gear 350 is connected to the active roller 410 via the second transmission shaft 360 . The driving motor 320 drives the active roller 410 to rotate.

[0097] Embodiment 4:

[0098] like Figure 2-Figure 7 As shown, the embodiment of the present application provides a household meat grinder. In addition to the above technical features, the detection mechanism 500 further includes:

[0099] The clamping block 510 is placed on the rotating seat 330;

[0100] Telescopic column 520, mounted on clamping block 510;

[0101] The telescopic slot 331 corresponds to the telescopic column 520;

[0102] The electrical connector 530 is respectively disposed at the end of the telescopic column 520 and the bottom of the telescopic slot 331 and corresponds to each other;

[0103] A micro motor 540 is installed in the rotating seat 330 , and the micro motor 540 is provided with a first threaded rod 541 ;

[0104] An internal thread seat 550 connected to the first threaded rod 541, wherein the internal thread seat 550 is provided with a push plate 551;

[0105] Among them, the rotating shaft 220 is provided with a limiting portion 230, the rotating seat 330 is provided with a limiting groove 332 corresponding to the limiting portion 230, and guide inclined surfaces 333 are provided on both sides of the limiting groove 332. The clamping block 510 is movably installed on the side wall of the limiting groove 332, and the clamping block 510 is provided with a pushing groove 511. The push plate 551 is placed in the pushing groove 511 and extends outward to be connected with the internal threaded seat 550, and first springs 512 that resist the pushing groove 511 are provided on both sides of the push plate 551.

[0106] When the rotating shaft 220 is installed and connected with the rotating seat 330, the limiting part 230 is placed in the limiting groove 332. The guiding inclined surface 333 facilitates the limiting part 230 to enter the limiting groove 332 when the rotating shaft 220 and the rotating seat 330 cooperate. The first spring 512 acts on the pushing groove 511, and the pushing groove 511 and the clamping block 510 are installed into an integrated structure. The limiting part 230 is clamped in the limiting groove 332 by the clamping block 510 to improve the stability between the rotating shaft 220 and the rotating seat 330. As the blade assembly 200 receives resistance during rotation, the limiting part 230 acts on the clamping block 510 to make the clamping block 510 shrink and move inward. The telescopic column 520 is installed and connected with the clamping block 510. During movement, the telescopic column 520 is placed in the telescopic slot 331 and moves. When the telescopic column 520 abuts against the bottom of the telescopic slot 331, the two corresponding electrical connectors 530 abut against each other, thereby enabling the micro-motor to be energized, and the first threaded rod 541 is driven to rotate through the micro-motor 540. The threaded pair connection between the first threaded rod 541 and the internal threaded seat 550 pushes the internal threaded seat 550 and the push plate 551 to move. The first spring 512 abuts against the push plate 551 and the push slot 511. When the push plate 551 moves, the force of the first spring 512 on the clamping block 510 is changed, so that the detection threshold of the detection mechanism 500 increases as the resistance to the rotation of the blade assembly 200 increases, and the clamping effect of the low limit portion 230 is guaranteed by the first spring 512.

[0107] Furthermore, the rotating seat 330 includes:

[0108] The adjusting block 600 is installed and connected with the internal thread seat 550, and the adjusting block 600 is provided with a first sliding groove 601;

[0109] The movable seat 610 is movably connected to the first transmission shaft 450;

[0110] The abutment plate 620 is movably connected to the movable seat 610;

[0111] Among them, the movable seat 610 is provided with a sliding column 611 corresponding to the first sliding groove 601, and the rotating seat 330 is provided with a second sliding groove 630 corresponding to the sliding column 611. The second sliding groove 630 limits the moving direction of the sliding column 611 to be the same as the axis of the first transmission shaft 450. The first sliding groove 601 and the second sliding groove 630 form an angle of 20°-80°, and the abutment plate 620 and the pushing part 441 are connected by a plurality of groups of folding parts 640.

[0112] As the resistance to the rotation of the blade assembly 200 increases, the detection threshold of the detection mechanism 500 rises, and the rotation speed of the blade assembly 200 increases. The adjustment block 600 is installed and connected to the internal thread seat 550 and moves at the same time. The movable seat 610 is connected to the first slide groove 601 on the adjustment block 600 and the second slide groove 630 on the rotating seat 330 through the slide column 611. The second slide groove 630 limits the movable seat 610 to move along the axial direction of the first transmission shaft 450. The first slide groove 601 and the second slide groove 630 form an angle of 20°-80°. When the adjustment block 600 moves, the movable seat 610 is pushed to move along the axial direction of the first transmission shaft 450 through the first slide groove 601.
