Description

Technical Field

[0001] This utility model relates to the field of meat grinders, and in particular to a wireless meat grinder structure. Background Technology

[0002] Meat grinders, as important food processing equipment, play a key role in the food industry. Their history can be traced back to ancient times, initially stemming from the basic human need for food processing. In the early days, they were mostly driven by human or animal power, with simple structures and low efficiency. With the arrival of the Industrial Revolution, meat grinders gradually became mechanized, and their production efficiency was greatly improved. They began to be widely used in homes and small food processing plants.

[0003] In existing meat grinder technology, the vast majority of meat grinders rely on corded power supply. The power cord becomes an inescapable constraint during use, confining users to the vicinity of the socket. The limited length of the power cord severely restricts the range of movement, making it difficult to flexibly adjust the placement of the meat grinder when the socket is poorly located in the kitchen. In outdoor camping or other scenarios without sockets, traditional meat grinders are completely useless, severely limiting their application scenarios. Furthermore, even when equipped with rechargeable batteries, traditional meat grinders often lack power indicators, making it impossible for users to intuitively know the remaining battery level. During the grinding process, it is common for the battery to run out, causing work interruptions, which not only wastes time but may also significantly shorten battery life due to over-discharge. In addition, traditional designs often use a motor to directly drive the meat grinding component. The motor's output characteristics are usually high speed and low torque. When dealing with meats with a lot of tendons or hard ingredients such as small bones, it often struggles to handle them, easily causing jamming. This disrupts the meat grinding process, severely impacting efficiency. Furthermore, due to the excessively high speed, it is difficult to finely process the ingredients, resulting in unevenly ground meat that greatly affects the subsequent cooking results and taste. At the same time, the auger and the bottom of the grinding cup in traditional meat grinders are often rigidly connected. Precise alignment is required during installation; even slight deviations can cause jamming. The installation process is time-consuming and laborious, and the forceful plugging and pulling during disassembly and maintenance can easily damage the components, increasing maintenance costs and usage risks. Utility Model Content

[0004] This invention provides a wireless meat grinder structure that can solve the problems of limited power supply and low power indication in existing meat grinders.

[0005] A wireless meat grinder structure includes a meat grinding cup and a wireless charging base. The top of the meat grinding cup is provided with a grinding head, which is aligned with the charging port of the wireless charging base. A motor is provided inside the grinding head, and the output end of the motor is aligned with the inside of the meat grinding cup. A wireless charging assembly and a reduction gear assembly are provided inside the grinding head. The wireless charging assembly includes a rechargeable lithium battery and a wireless charging module. The rechargeable lithium battery is electrically connected to the motor, and the wireless charging module is electrically connected to the rechargeable lithium battery and is compatible with the wireless charging base. The output end of the motor is connected to the reduction gear set.

[0006] Preferably, the reduction gear set includes a first gear and a second gear; The first gear is fixedly connected to the output end of the motor and is coaxial; The first gear meshes with the second gear, and an auger is fixedly connected to the center of the side of the second gear away from the motor.

[0007] Preferably, the diameter of the first gear is smaller than that of the second gear, and both the first gear and the second gear are rotatably connected in the machine head.

[0008] Preferably, the other end of the auger that is connected to the second gear is rotatably connected to the bottom of the meat grinder cup. The end of the auger is hollow inside and has a groove in its inner wall, and a spring is provided in the groove.

[0009] Preferably, the spring element includes a locking block and a spring; The card block is placed horizontally in the groove. The upper surface of one end is flat, and the lower surface is arc-shaped and can be inserted into the hollow part of the auger. The other end is fixedly connected to the spring. The other end of the spring, away from the locking block, is fixedly connected to the auger.

[0010] Preferably, the bottom of the auger is provided with a latching assembly; The buckle assembly includes a column, a base, a first stop, and a second stop; The bottom of the column is fixedly installed at the center of the base, and its top is aligned with the center of the auger. The first stop block is fixedly installed on the top of the column; The second stop is located below the first stop and is fitted onto the outer wall of the column. The second stop can move up and down along the vertical direction of the column.

[0011] Preferably, the first stop is semi-circular, with a diameter equal to the hollow diameter of the auger, and the flat surface of the first stop abuts against the flat surface of the locking block.

[0012] Preferably, the second stop is a symmetrical frustum, with its symmetrical surface being the base of the frustum, and the arcuate surface of the second stop can abut against the arcuate surface of the locking block.

[0013] Preferably, a switch is provided on the top of the machine head, and the switch is electrically connected to the motor.

[0014] Preferably, the head unit is provided with a power indicator light that is electrically connected to a rechargeable lithium battery.

[0015] The beneficial effects of this utility model are as follows: Through the electromagnetic induction adaptation between the wireless charging module inside the head and the wireless charging base, and in conjunction with a rechargeable lithium battery, the motor is powered, eliminating the need for power cords and sockets. Users can freely use it in power-free scenarios such as kitchen countertops and outdoor camping, completely freeing themselves from the constraints of wires. Furthermore, the power indicator light is electrically connected to the rechargeable lithium battery, providing feedback on charging progress and remaining power through light color or flashing frequency. A short press of the switch during standby can also trigger the power display, solving the problem of blindly judging the power level in traditional wireless devices. This avoids interrupting meat grinding due to insufficient power or damaging the battery due to over-discharge, significantly improving the flexibility and convenience of use. Simultaneously, through the transmission cooperation between the motor output end and the reduction gear set, where the first gear is coaxially fixed with the motor and the second gear meshes with the first gear and has a larger diameter, gear transmission is utilized. The principle of this design converts the high-speed, low-torque output of the motor into low-speed, high-torque output from the second gear. This second gear then drives the auger to rotate, ensuring that the auger receives sufficient torque to grind meat with a lot of tendons or a small amount of bone, avoiding the jamming caused by insufficient torque in traditional direct drives. In addition, through the rotating connection between the bottom of the auger and the meat grinder cup, and the coordinated operation of the latch assembly and spring components, the column provides vertical support for the auger through the base. The flat surfaces of the first stop and the latch block abut against each other to form a circumferential limit, preventing axial movement or circumferential slippage when the auger rotates at high speed. When disassembling, pressing the auger causes the arc surface of the second stop to press against the arc surface of the latch block, pushing the latch block to compress the spring and retract into the groove, thus releasing the limit and easily removing the auger. This solves the problems of jamming during disassembly and assembly and easily damaged parts in traditional rigid connections, balancing the stability of auger operation and ease of maintenance.

[0018] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0019] like Figures 1 to 3 As shown in the figure, the present invention provides a wireless meat grinder structure, including a meat grinder cup 1 and a wireless charging base 2. The top of the meat grinder cup 1 is provided with a head 3, which is aligned with the charging port of the wireless charging base 2. The head 3 is provided with a motor 4, the output end of which is aligned with the inside of the meat grinder cup 1. The head 3 is provided with a wireless charging group 5 and a reduction gear group 6. The wireless charging group 5 includes a rechargeable lithium battery 51 and a wireless charging module 52. The rechargeable lithium battery 51 is electrically connected to the motor 4, and the wireless charging module 52 is electrically connected to the rechargeable lithium battery 51 and is adapted to the wireless charging base 2. The output end of the motor 4 is connected to the reduction gear set 6.

[0020] Traditional meat grinders mostly rely on wired power, which is limited by the location of the socket and the length of the power cord, resulting in fixed usage scenarios and poor flexibility. In addition, if the motor 4 directly drives the meat grinding component, the meat is often not ground completely or the machine jams due to excessive speed and insufficient torque. By setting up a rechargeable lithium battery 51 and a wireless charging module 52, the power cord is completely eliminated. Users can use it freely in scenarios without sockets, such as kitchen countertops or outdoor camping, solving the space limitation problem of traditional wired designs. The wireless charging module 52 is compatible with the wireless charging base 2, and charging can be achieved without plugging and unplugging the power cord, reducing the risk of interface wear and improving the ease of operation. In addition, the output end of the motor 4 is connected to the reduction gear set 6, which can convert the high-speed, low-torque output of the motor 4 into the low-speed, high-torque output required for meat grinding, ensuring stable grinding even when dealing with tough meats or large amounts of ingredients, avoiding jamming, and improving meat grinding efficiency and stability.

[0021] In the initial state, the meat grinder cup 1 and the head 3 are assembled as one unit. The rechargeable lithium battery 51 inside the head 3 establishes a pairing relationship with the wireless charging base 2 through the wireless charging module 52. When the head 3 is placed with the charging port of the wireless charging base 2 aligned, the wireless charging module 52 receives the electrical energy transmitted by the wireless charging base 2 through electromagnetic induction to charge the rechargeable lithium battery 51. After charging is completed, the rechargeable lithium battery 51 serves as a power source to supply power to the motor 4 inside the head 3. When the motor 4 starts, its output end transmits power to the reduction gear set 6. Through the speed adjustment and torque conversion of the reduction gear set 6, the power is directed to the meat grinding execution component inside the meat grinder cup 1, ultimately realizing the meat grinding operation in the wireless power supply state.

[0022] The reduction gear set 6 includes a first gear 61 and a second gear 62; The first gear 61 is fixedly connected to the output end of the motor 4 and is coaxial; The first gear 61 meshes with the second gear 62, and the auger 7 is fixedly connected to the center of the side of the second gear 62 away from the motor 4.

[0023] If motor 4 directly drives auger 7, excessive speed can easily cause food to splatter, or unstable power transmission can cause auger 7 to shake and produce excessive noise. By using the meshing structure of the first gear 61 and the second gear 62 in the reduction gear set 6, the first gear 61 is coaxially fixed to the output end of motor 4, ensuring no deviation in power transmission; the second gear 62 is directly connected to auger 7, achieving stable power transmission through gear meshing. This avoids the shaking problem of traditional direct drive methods. This structure is simple and has high transmission efficiency, accurately transmitting the power of motor 4 to auger 7, ensuring uniform auger 7 speed, resulting in finer and more even food grinding, while reducing noise caused by power fluctuations and improving the user experience.

[0024] After the motor 4 starts, its output end drives the first gear 61, which is fixed on the same axis, to rotate synchronously. Since the first gear 61 and the second gear 62 mesh with each other, the rotation of the first gear 61 is transmitted to the second gear 62 through the meshing of the tooth surfaces, driving the second gear 62 to rotate in the opposite direction. At this time, the auger 7, which is fixedly connected to the center of the second gear 62, rotates synchronously with the second gear 62, directly converting the power converted by the reduction gear set 6 into the rotational kinetic energy of the auger 7, so that the auger 7 rotates at high speed in the meat grinder cup 1 to cut and grind the ingredients in the cup.

[0025] The diameter of the first gear 61 is smaller than that of the second gear 62. Both the first gear 61 and the second gear 62 are rotatably connected in the machine head 3.

[0026] Meat grinding requires a large torque to cut the meat fibers, but the motor 4 typically outputs high speed and low torque. If the first gear 61 and the second gear 62 have the same diameter, it is impossible to reduce speed and increase torque, which may result in insufficient torque for the auger 7, making it difficult to process harder ingredients. By limiting the diameter of the first gear 61 to be smaller than that of the second gear 62, and utilizing the principle of gear transmission ratio, when the motor 4 drives the smaller diameter first gear 61 to rotate, the speed of the second gear 62 decreases, and the torque increases proportionally. This ensures that the auger 7 can easily grind meat with a lot of tendons or a small amount of bone, thereby improving the load capacity and applicability of the equipment.

[0027] When the motor 4 drives the small-diameter first gear 61 to rotate at high speed, the first gear 61 drives the large-diameter second gear 62 to rotate through tooth surface meshing. Since the gear transmission ratio is proportional to the diameter, the speed of the second gear 62 is lower than that of the first gear 61, and the torque increases proportionally. In addition, the two gears are rotatably connected in the machine head 3 through bearings and other structures to ensure that the gear axis does not deviate during rotation, and to avoid power loss or jamming caused by tooth surface meshing deviation.

[0028] The other end of the auger 7, which is rotatably connected to the second gear 62, is rotatably connected to the bottom of the meat grinder cup 1. Its end is hollow inside and has a groove in its inner wall. A spring 8 is installed in the groove.

[0029] The spring component 8 includes a locking block 81 and a spring 82; The card block 81 is placed horizontally in the groove. The upper surface of one end is flat, the lower surface is arc-shaped and can be inserted into the hollow part of the auger 7, and the other end is fixedly connected to the spring 82. The other end of the spring 82, away from the locking block 81, is fixedly connected to the auger 7.

[0030] If the auger 7 is rigidly connected to the bottom fixed structure, it is prone to jamming during installation due to misalignment. Disassembly requires forceful insertion and removal, which can easily damage components. The solution utilizes a locking block 81 and a spring 82 in the spring component 8. The locking block 81 has one straight end and one curved end connected to the spring 82. The elastic potential energy of the spring 82 enables the automatic extension and retraction of the locking block 81. When the auger 7 is installed, the curved surface of the locking block 81 is pressed by the latching assembly 9, compressing the spring 82 and retracting into the groove, facilitating the alignment of the auger 7. After installation, the spring 82 resets, pushing the locking block 81 out, with the straight end abutting against the latching assembly 9, achieving circumferential positioning and preventing slippage during rotation of the auger 7. During disassembly, applying force in the opposite direction allows the locking block 81 to compress the spring 82 again, easily separating the auger 7 from the latching assembly 9. This design ensures the stability of the auger 7 during operation, simplifies the installation and disassembly process, and improves maintenance convenience.

[0031] The bottom of the auger 7 is provided with a buckle assembly 9; The buckle assembly 9 includes a column 91, a base 92, a first stop 93, and a second stop 94; The bottom of the column 91 is fixedly installed at the center of the base 92, and its top is aligned with the center of the auger 7. The first stop block 93 is fixedly installed on the top of the column 91; The second stop 94 is located below the first stop 93 and is fitted onto the outer wall of the column 91. The second stop 94 can move up and down along the vertical direction of the column 91.

[0032] If the bottom of the auger 7 lacks stable support, axial movement may occur during high-speed rotation, affecting the meat grinding accuracy. Vertical support is provided by the column 91 and the base 92. The top of the column 91 is aligned with the center of the auger 7 to ensure coaxiality during operation. The first stop 93 is fixed to the top of the column 91 to limit the axial displacement of the auger 7. The second stop 94 is fitted on the outer wall of the column 91 and can move up and down. It works with the spring 8 inside the auger 7 to achieve unlockable fixation. This structure not only provides stable bottom support for the auger 7 and reduces axial movement, but also allows for quick assembly and disassembly of the auger 7 by moving the second stop 94. During installation, pressing down the second stop 94 unlocks the locking block 81, and lifting the second stop 94 releases the locking block 81 during disassembly.

[0033] The first stop block 93 is semi-circular, and its diameter is equal to the hollow diameter of the auger 7. The flat surface of the first stop block 93 abuts against the flat surface of the locking block 81.

[0034] If the shape of the first stop 93 does not match the hollow part of the auger 7, or cannot be precisely aligned with the locking block 81, it will cause circumferential slippage when the auger 7 rotates, affecting the meat grinding efficiency. By limiting the first stop 93 to a semi-circular arc shape with a diameter equal to the hollow diameter of the auger 7, it is ensured that the first stop 93 can be precisely embedded in the end of the auger 7. At the same time, its flat surface abuts against the flat surface of the locking block 81, forming a circumferential positioning with surface contact. By utilizing the friction and limiting effect between the planes, it prevents the auger 7 from slipping relative to the locking assembly 9 when rotating. This design ensures the synchronous rotation of the auger 7 and the locking assembly 9, avoids power loss caused by slippage, ensures a continuous and stable meat grinding process, and improves energy utilization efficiency.

[0035] The second stop 94 is a symmetrical frustum, with its symmetrical surface being the bottom surface of the frustum. The arc surface of the second stop 94 can abut against the arc surface of the locking block 81.

[0036] If the contact surface between the second stop 94 and the locking block 81 is flat, it is easy to cause jamming when pushing the locking block 81 to extend or retract, affecting the smoothness of disassembly and assembly. By designing the second stop 94 as a symmetrical frustum shape, its arc surface matches the arc surface of the locking block 81. Utilizing the smooth transition characteristics of the arc surface, when the second stop 94 moves up and down, the rolling contact between the arc surface and the arc surface of the locking block 81 can convert the vertical force into a horizontal force that pushes the locking block 81 to extend or retract, reducing frictional resistance. This design makes the pressing-down unlocking action during installation and the lifting-up release action during disassembly of the auger 7 smoother, avoiding jamming, improving the user's operating feel, and reducing component wear and extending service life.

[0037] Screw 7 installation stage: When screw 7 is installed downwards, its hollow bottom part is aligned with the column 91 of the buckle assembly 9. The top part of the column 91 presses the arc-shaped lower surface of the buckle block 81. After being pressed, the buckle block 81 compresses the spring 82 along the transverse groove and retracts into the groove to avoid interference with the column 91, ensuring that the screw 7 is smoothly installed downwards to the designated position. During the operation of auger 7: After installation, spring 82 releases elastic potential energy, pushing the locking block 81 out of the groove. Its flat upper surface abuts against the first stop 93 of the buckle assembly 9, forming a circumferential limit. When auger 7 rotates with the second gear 62, the contact between the locking block 81 and the first stop 93 restricts the auger 7 from slipping circumferentially relative to the column 91, ensuring that auger 7 and buckle assembly 9 are positioned synchronously and avoiding rotational deviation. Screw 7 disassembly stage: When screw 7 needs to be disassembled, press down on screw 7. The arc surface of the locking block 81 is squeezed by the second stop 94, and the compression spring 82 retracts into the groove. At this time, the second stop 94 moves up to the bottom of the first stop 93. Then pull screw 7 up to release the limit of the buckle assembly 9 and realize the quick disassembly of screw 7.

[0038] The top of the machine head 3 is provided with a switch 10, which is electrically connected to the motor 4.

[0039] After the user prepares the ingredients and assembles the meat grinder, press the switch 10 on the top of the machine head 3. The motor 4 is powered on and starts, completing the power transmission and meat grinding operation. When the ingredients are ground, press the switch 10 again to disconnect the circuit, stop the motor 4, and the auger 7 will stop rotating. If it is necessary to pause in the middle, it can also be done by pressing the switch 10.

[0040] The head unit 3 is equipped with a power indicator light that is electrically connected to the rechargeable lithium battery 51.

[0041] If a wireless device lacks a power indicator, users will have difficulty judging the remaining power and may be forced to stop the process due to depletion of power during meat grinding, affecting the user experience. At the same time, over-discharge will shorten the life of the lithium battery. By setting a power indicator light connected to the rechargeable lithium battery 51 on the head unit 3, the power status can be displayed intuitively through the color of the light or the flashing frequency. Users can check the power level in advance before use to avoid power interruption. During charging, the indicator light can be used to judge the charging progress, prevent overcharging, extend battery life, improve the reliability of the device and the user's sense of control.

[0042] Charging phase: Place the head unit 3 on the wireless charging base 2. The wireless charging module 52 charges the rechargeable lithium battery 51. The power indicator light reflects the charging progress through different colors or flashing frequencies. Users can intuitively judge the charging status and avoid overcharging or undercharging. Usage phase: When the rechargeable lithium battery 51 powers the motor 4, the power indicator light displays the remaining power in real time. If the power is lower than the threshold, the indicator light flashes to remind the user and prevent the user from being forced to stop the machine due to the power running out during the meat grinding process. Standby phase: When the device is not started, a short press of the switch 10 will trigger the power indicator light to light up briefly. Users can check the power level without starting the motor 4, which makes it easier to plan charging or use in advance.

[0043] In summary, the wireless meat grinder structure provided by this utility model embodiment allows for charging during use. The integrated meat grinder cup 1 and head 3 are placed on the wireless charging base 2, ensuring precise alignment between the head 3 and the charging port of the wireless charging base 2. At this time, the wireless charging module 52 of the wireless charging group 5 inside the head 3 receives electrical energy transmitted from the wireless charging base 2 through electromagnetic induction, replenishing the rechargeable lithium battery 51. During charging, the power indicator light on the head 3 reflects the charging progress through different colors or flashing frequencies. If the device is in standby mode, a short press of the switch 10 on the top of the head 3 will also trigger the power indicator light to illuminate briefly, allowing for convenient viewing of the remaining power and advance planning of usage. After the rechargeable lithium battery 51 is fully charged, the meat grinding preparation stage begins: the ingredients to be ground are placed into the meat grinding cup 1, and then the meat grinding cup 1 is ensured to be tightly assembled with the machine head 3. At this time, the hollow part at the bottom of the auger 7 is aligned with the column 91 of the buckle assembly 9, and the first stop 93 at the top of the column 91 is embedded in the hollow part of the auger 7. The spring 81 in the groove of the inner wall of the auger 7 extends out under the elastic potential energy of the spring 82, and its flat upper surface abuts against the flat surface of the first stop 93 to form a circumferential limit. Press the switch 10 on the top of the machine head 3 to start the equipment. The output end of the motor 4 drives the first gear 61, which is fixed on the same axis, to rotate synchronously at high speed. The first gear 61 drives the second gear 62 to rotate through the meshing of the tooth surfaces. Utilizing the principle of gear transmission ratio, the speed of the second gear 62 decreases while the torque increases proportionally. As the second gear 62 rotates, the auger 7, which is fixedly connected to it, rotates synchronously to cut and grind the ingredients in the cup. After the ingredients are ground, press the switch 10 again to disconnect the circuit, stop the motor 4, and stop the auger 7. If it is necessary to clean or change the ingredients, disassemble the auger 7, then clean the meat grinder cup 1 and the auger 7. After cleaning, reset them according to the above installation steps and wait for the next use.

[0044] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
