Description

Technical Field

[0001] This utility model relates to the field of shredder technology, and in particular to a shredder that can toughen meat. Background Technology

[0002] In the food processing industry, especially in home kitchens and small catering establishments, chopping and grinding meat are common operational needs. Traditional meat chopping equipment typically only has a single chopping function, using a motor to drive blades to rotate at high speed to cut meat into small pieces or mince.

[0003] However, this traditional equipment has problems in practical use. Relying solely on chopping cannot meet certain cooking needs. For example, when making meatballs or meat patties, the chopped meat needs to be stirred and mixed to increase its elasticity and improve the texture and quality of the dish. Traditional equipment cannot perform this function; users must transfer the chopped meat to other containers and use additional tools to stir and mix it, which is cumbersome and inefficient. Utility Model Content

[0004] The purpose of this invention is to disclose a meat chopper that can be used to toughen meat.

[0005] To achieve the above objectives, this utility model discloses a meat chopper capable of firming meat, comprising: a mixing cup having a mixing chamber with an open top; a main unit cover covering the opening of the mixing chamber; a circuit board assembly mounted in the main unit cover; a motor assembly mounted in the main unit cover and electrically connected to the circuit board assembly; and a mixing blade assembly, one end of which is drivenly connected to the motor assembly, and the other end extending into the mixing chamber. The mixing blade assembly extending into the mixing chamber includes a mixing blade having a cutting edge and a backing edge. The cutting edge is configured to cut food, and the backing edge is configured to stir food. The circuit board assembly controls the motor assembly to rotate forward or backward to drive the mixing blade assembly to cut or stir food.

[0006] By adopting the above solution, a circuit board assembly and a motor assembly are installed inside the main unit's cover. The assembly features a mixing blade with one side having an open blade and the other side having an unsharpened back. When food chopping begins, the circuit board assembly controls the motor assembly to rotate forward, driving the mixing blade assembly to chop the meat. After a certain period of chopping detection, the circuit board assembly determines the food type based on stable current information from a current sensor and controls a timer to set the clockwise rotation time of the blades. After the clockwise rotation is completed within the specified time, the circuit board assembly controls the motor assembly to rotate in reverse, causing the back of the blades to stir the meat without chopping, thus achieving a firming effect on the meat. This design integrates meat chopping and firming functions into one unit, eliminating the need for users to transfer chopped meat to other containers for secondary processing. This greatly simplifies the operation process, improves processing efficiency, meets specific cooking needs, and enhances the taste and quality of the dishes.

[0007] Furthermore, the main unit cover includes: a top cover; a main unit body, the main unit body having an assembly cavity, the circuit board assembly and the motor assembly being assembled in the assembly cavity, the top cover being disposed on the top of the assembly cavity; a body cover, the body cover being connected to the bottom of the assembly cavity; and a cup cover, the cup cover being sealed to the stirring chamber, the body cover being snapped into the cup cover.

[0008] By adopting the above solution, the main body cover is disassembled into multiple independent components. During production, the top cover, main body, main body cover, and cup lid can be manufactured and processed separately. The production process for each component can be more focused and precise, improving production efficiency and product quality. The layered design provides precise positioning for the internal components. The various components are fixed together using specific connection methods, such as snap-fit ​​connections and threaded connections, ensuring the stability and robustness of the overall structure of the main body cover and reducing the possibility of components loosening or falling off during use due to vibration or external forces.

[0009] Furthermore, the stirring cup is a reverse-sloping stirring cup, which includes a side wall section, a chamfered section and a bottom wall section from the opening to the bottom. The side wall section is inclined from top to bottom away from the central axis of the cup body, and the bottom wall section has a concave rotating groove in the center for rotatably connecting with the other end of the stirring blade assembly.

[0010] By adopting the above design, the sidewall section is inclined from top to bottom away from the central axis of the cup. This reverse inclination design ensures that during the mixing process, when the ingredients are moved outward by the centrifugal force of the mixing blades, they will move upward along the inclined sidewall section. The downward suction generated by the rotation of the mixing blades will cause some ingredients to move downward, thus creating a circulating mixing flow within the mixing cup. This circulating flow allows the ingredients to come into more thorough contact with the mixing blades, improving the uniformity of mixing and preventing areas of insufficient mixing. Because the ingredients can form an effective circulating flow within the mixing cup, the mixing blades can cut and mix the ingredients more quickly, thereby shortening the mixing time and improving mixing efficiency. At the same time, the uniform mixing effect also helps to improve the quality of the final food product, such as a more delicate and even texture.

[0011] Furthermore, the angle between the sidewall segment and the bottom wall segment is 87°.

[0012] By employing the above method, during the mixing process, the high-speed rotation of the mixing blades generates centrifugal force, causing the ingredients to move upwards along the sidewall. This specific angle guides the ingredients, after reaching a certain height, to flow back downwards more smoothly along the interface between the sidewall and the bottom wall, forming a good circulation flow.

[0013] Furthermore, the circuit board assembly includes interconnected circuit boards, a current detection device, and a timing device. The current detection device is used to determine the ingredients by observing the stable flow of the stirring blade rotating within a specified time. The timing device is used to control the duration of the motor assembly rotating forward or backward.

[0014] By employing the above solution, different ingredients exert varying resistance on the mixing blades during the mixing process, thus affecting the motor's operating current. A current detection device monitors the stable current flow during the mixing blade rotation over a specified time, precisely sensing subtle changes in current to accurately determine the type, hardness, density, and other characteristics of the ingredients. A timing device can then precisely control the forward or reverse rotation duration of the motor assembly based on the ingredient characteristics determined by the current detection device. For harder ingredients, the forward and reverse rotation time is appropriately extended to ensure thorough mixing and chopping; for softer ingredients, the mixing time is shortened to avoid over-mixing and a deterioration in texture. This intelligent mixing control improves mixing efficiency and quality, resulting in more delicious food.

[0015] Furthermore, a base is provided outside the stirring cup, and a first fixing member is hinged to at least two sides of the base. A second fixing part is provided on the main body cover. The first fixing member and the second fixing part are detachably connected. A suction cup structure is provided at the bottom of the base.

[0016] By adopting the above solution, the high-speed rotation of the mixing blade assembly during the mixing process generates significant centrifugal force, which can easily cause the mixing cup to shake or even shift. The base, in conjunction with the first and second fixing parts, firmly secures the mixing cup, effectively resisting this centrifugal force and ensuring its stability during mixing. This prevents shaking from affecting the mixing effect or even causing food spillage or equipment damage. The detachable connection method allows for separate cleaning of the main body cover, mixing cup, and base. This component can be replaced individually without replacing the entire mixing cup assembly, and the suction cup structure enhances the stability of the base.

[0017] Furthermore, the circuit board is fixed to the top of the main body, and an elastic element is provided between the top cover and the circuit board. The elastic element is used to provide a pre-pressure for the circuit board to displace towards the main body.

[0018] By adopting the above solution, when the top cover is subjected to external force, the elastic element will deform, absorbing and dispersing some of the impact energy, thereby reducing the impact force transmitted to the circuit board, protecting the electronic components on the circuit board from damage, and extending the service life of the circuit board. The elastic element can also isolate vibration, consuming vibration energy through its own elastic deformation, greatly reducing the impact of vibration on the circuit board and ensuring the stable operation of the circuit board.

[0019] Further, the motor assembly includes: a drive motor, one end of which is connected to a first drive shaft, and the other end of which is connected to a second drive shaft disposed on the central axis of the first drive shaft, the first drive shaft being drivenly connected to one end of the stirring blade assembly; a cooling fan, the cooling fan being drivenly connected to the second drive shaft; and a motor mounting bracket, the motor mounting bracket being connected between the first drive shaft and the drive motor, and between the second drive shaft and the drive motor.

[0020] By adopting the above solution, the cooling fan rotates simultaneously with the drive motor. This design allows the cooling fan to dissipate heat from the drive motor in real time, eliminating the need for an additional power source to drive the fan, thus improving energy efficiency. It also ensures that the drive motor will not be damaged by overheating during prolonged operation, extending its lifespan. Compared to using a separate motor to drive the cooling fan, this design better coordinates the fan's speed and noise, achieving lower noise operation.

[0021] Furthermore, a gearbox assembly is provided between the first drive shaft and the stirring blade assembly.

[0022] By adopting the above scheme, the gearbox assembly contains combinations of gears of different sizes and numbers of teeth. Through the meshing transmission of these gears, the torque and speed transmitted from the first drive shaft can be flexibly adjusted according to the working requirements of the agitator assembly. Compared with direct drive, the gearbox assembly can more effectively transmit the power from the first drive shaft to the agitator assembly, reducing power loss caused by friction, slippage, and other factors, thereby reducing energy consumption and improving the overall performance of the equipment.

[0023] Furthermore, the gearbox assembly includes: a first drive tooth, which drives coaxially with the first drive shaft; a second transmission gear disk assembly, which includes an internal gear disk and a plurality of intermediate teeth distributed circumferentially along the internal gear of the internal gear disk, the intermediate teeth meshing with both the first drive tooth and the internal gear disk, and the internal gear disk having a meshing groove in the center; and a third drive tooth, one end of which meshes with the meshing groove of the internal gear disk, and the other end of which is drivenly connected to the stirring blade assembly.

[0024] By adopting the above scheme, the multi-stage gear meshing transmission method reduces unnecessary energy conversion and transmission links compared to some complex transmission structures. This gearbox assembly design allows for different transmission ratios. When the resistance of the food being mixed is low, a higher transmission ratio can be selected, allowing the mixing blades to operate at a higher speed and quickly complete the mixing task. When mixing harder food or encountering greater resistance, the transmission ratio can be automatically adjusted to a lower ratio to increase torque output and ensure the mixing blades function properly.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This product integrates chopping and mixing functions into one unit, eliminating the need for transfer or secondary processing. Users simply place the meat into the mixing chamber, and the circuit board assembly controls the motor assembly to rotate forward and backward, sequentially completing the chopping and mixing process. This significantly simplifies the operation, saving time and effort. By reducing intermediate transfer and secondary processing steps, the entire meat processing process is more seamless and efficient. Users can complete meat preparation faster, allowing more time for subsequent cooking, thus improving overall cooking efficiency. This is particularly suitable for use in time-sensitive scenarios such as home kitchens and small restaurants. 2. Breaking through the limitations of traditional meat chopping equipment that only has a single chopping function, this machine integrates both chopping and mixing / strengthening functions. This multi-functional integrated design meets the diverse needs of different cooking scenarios. Whether making dumplings or buns that require chopped meat filling, or meatballs or meat patties that require mixing and strengthening, this machine can complete the task, improving its practicality and cost-effectiveness. By using the back of the blade to mix and strengthen the chopped meat, it can better simulate the effect of hand mixing, allowing the meat to fully develop its elasticity, thereby significantly improving the taste and quality of the dish. This allows users to create more delicious, professional-grade dishes. The design of the blade back allows the meat to roll and mix thoroughly in the mixing chamber, ensuring that every part of the meat is evenly mixed and strengthened. Compared to the traditional method of using additional tools for mixing, this avoids the problem of some meats being under-stirred or over-mixed due to uneven mixing, ensuring the quality and consistency of the processed ingredients. 3. The design of the mixing cup allows ingredients within the mixing chamber to more easily concentrate near the mixing blades during mixing, improving mixing efficiency and promoting thorough mixing and elasticity. The main unit cover houses the circuit board assembly and motor assembly, resulting in a more compact and rational overall structure, saving space and facilitating storage and portability. The main unit cover, positioned over the opening of the mixing chamber, effectively prevents food from splashing out during operation, avoiding burns to the user or soiling the surrounding environment. Simultaneously, the circuit board assembly provides precise and reliable forward and reverse control of the motor assembly, reducing equipment malfunctions and unexpected situations, and ensuring user safety.

[0034] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0035] Please refer to Embodiment 1 of this utility model. Figures 1 to 7 As shown, a meat chopper that can be gluten-refining is provided, including a mixing cup 1, a main unit cover 2, a circuit board assembly 3, a motor assembly 4, and a mixing blade assembly 5. The various parts work together to realize the integrated operation of meat chopping and gluten-refining, meeting the diverse needs of home kitchens and small catering establishments for meat processing.

[0036] The mixing cup 1 is a reverse-sloping mixing cup with a mixing chamber 11 having a top opening 12. From the opening 12 downwards, it includes a side wall section 13, a chamfered section 14, and a bottom wall section 15. Preferably, the side wall section 13 is inclined from top to bottom away from the central axis of the cup body. In this embodiment 1, the angle between the side wall section 13 and the bottom wall section 15 is 87°. In other embodiments, it can be between 75° and 89°. A concave groove 151 is provided in the center of the bottom wall section 15. During the mixing process, meat ingredients are placed into the mixing chamber 11. When the mixing blade assembly 5 rotates, the ingredients are subjected to centrifugal force and move outwards, moving upwards along the inclined side wall section 13. At the same time, the downward suction generated by the rotation of the mixing blade assembly 5 causes some ingredients to move downwards. Guided by the 87° angle, after reaching a certain height, the ingredients flow back downwards more smoothly along the junction area of ​​the side wall and the bottom wall, forming a good circulating mixing flow in the mixing cup. This circulating flow ensures that the ingredients fully contact the mixing blade assembly 5, improving mixing uniformity, shortening mixing time, and enhancing the final food quality, such as making the minced meat more delicate and uniform in texture. Finally, under the action of the downward-sloping upper blade in the mixing blade assembly 5, the food is pushed away from the center and onto the lower blade, achieving a circular tumbling and chopping motion within the mixing chamber 11, thus improving chopping efficiency. Furthermore, the mixing chamber 11, with its side wall section 13, chamfered section 14, and bottom wall section 15, has a near-triangular cross-section, ensuring the stability of the chamber, reducing vibration, and thus lowering chopping noise.

[0037] The main unit cover 2 includes a top cover 21, a main unit body 22, a main body cover 23, and a cup cover 24. The main unit body 22 has an assembly cavity 221, within which the circuit board assembly 3 and the motor assembly 4 are assembled. The top cover 21 covers the top of the assembly cavity 221. The main body cover 23 is connected to the bottom of the assembly cavity 221. The cup cover 24 is sealed to the stirring chamber 11, and the main body cover 23 and the cup cover 24 are fastened together. During production, the top cover 21, the main unit body 22, the main body cover 23, and the cup cover 24 are manufactured and processed separately. Each component employs a production process suitable for its structure and function; for example, the top cover 21 can be produced using injection molding to ensure a smooth surface and dimensional accuracy. The assembly cavity 221 of the main unit body 22 is precisely designed according to the dimensions of the circuit board assembly 3 and the motor assembly 4, providing precise positioning for the internal components. The various components are fixed together by specific connection methods such as snap-fit ​​connections and threaded connections to ensure the stability and firmness of the overall structure of the main unit cover 2, and reduce the loosening or falling off of components due to vibration or external force during use.

[0038] In this embodiment 1, the circuit board assembly 3 includes an interconnected circuit board 31, a current detection device 32, and a timing device 33. During the operation of the chopper, the current detection device 32 monitors the stable flow of the rotating blade 51 within a specified time. Different ingredients exert different resistances on the stirring blade 51 during the stirring process, which affects the operating current of the motor. By sensing subtle changes in the current, the current detection device 32 accurately determines the type, hardness, density, and other characteristics of the ingredients. Based on the characteristics of the ingredients determined by the current detection device 32, the timing device 33 precisely controls the duration of forward or reverse rotation of the motor assembly 4. For example, when a relatively hard meat is detected, the timing device 33 appropriately extends the forward and reverse rotation time to ensure that the ingredients are fully stirred and chopped; when a relatively soft ingredient is detected, the stirring time is shortened to avoid over-stirring and resulting in a deterioration in the texture of the ingredients.

[0039] In some embodiments, to simultaneously achieve self-heating, the motor assembly 4 includes a drive motor 41, a first drive shaft 411, a second drive shaft 412, a cooling fan 42, and a motor mounting bracket 43. One end of the drive motor 41 is connected to the first drive shaft 411, and the other end is connected to the second drive shaft 412, which is axially aligned with the first drive shaft 411. The first drive shaft 411 is driven to one end of the stirring blade assembly 5. The cooling fan 42 is driven to the second drive shaft 412. The motor mounting bracket 43 is connected between the first drive shaft 411 and the drive motor 41, and between the second drive shaft 412 and the drive motor 41. After the drive motor 41 starts, it simultaneously drives the first drive shaft 411 and the second drive shaft 412 to rotate. The first drive shaft 411 transmits power to the stirring blade assembly 5, driving it to perform chopping or stirring operations. The second drive shaft 412 drives the cooling fan 42 to rotate, which in turn cools the drive motor 41 in real time. This eliminates the need for an external power source, improving energy efficiency and ensuring the drive motor 41 will not be damaged by overheating during prolonged operation, thus extending its lifespan. The motor mounting bracket 43 provides stable support, reducing vibration and noise during motor operation and ensuring stable operation. The motor mounting bracket 43 is rotatably connected to both the first drive shaft 411 and the second drive shaft 412, for example, by means of bearings.

[0040] In this embodiment 1, one end of the mixing blade assembly 5 is driven and connected to the first drive shaft 411 of the motor assembly 4, and the other end extends into the mixing chamber 11. The mixing blade assembly 5 extending into the mixing chamber 11 includes a mixing blade 51, one side of which has an open blade 511, and the other end has an unsharpened blade back 512. When food chopping begins, the circuit board assembly 3 controls the motor assembly 4 to rotate forward, driving the blade 511 of the mixing blade assembly 5 to chop the meat. After a certain period of chopping detection, the circuit board assembly 3 determines the type of food based on the stable current information fed back by the current detection device 32, and controls the timer to set the clockwise rotation time of the blade 511. After the clockwise rotation is completed within the specified time, the circuit board assembly 3 then controls the motor assembly 4 to rotate in reverse, so that the blade back 512 stirs the meat without chopping it. The design of the blade back 512 allows the meat to tumble and mix thoroughly in the mixing chamber 11, ensuring that each part of the meat is evenly stirred and strengthened, simulating the effect of hand stirring, and improving the taste and quality of the dish.

[0041] The gearbox assembly 8 is disposed between the first drive shaft 411 and the stirring blade assembly 5. In this embodiment 1, the gearbox assembly 8 includes a first drive tooth 81, a second transmission gear disk assembly 82, and a third drive tooth 83. The first drive tooth 81 is coaxially driven with the first drive shaft 411. The second transmission gear disk assembly 82 includes an internal gear disk 821 and a plurality of intermediate teeth 822 distributed circumferentially along the internal gear of the internal gear disk 821. The intermediate teeth 822 mesh with both the first drive tooth 81 and the internal gear disk 821. The internal gear disk 821 also has a meshing groove 823 in the center. One end of the third drive tooth 83 meshes with the meshing groove 823 of the internal gear disk 821, and the other end is drivenly connected to the stirring blade assembly 5. When the first drive shaft 411 rotates, it drives the first drive tooth 81 to rotate synchronously. The first drive tooth 81 transmits power to the intermediate teeth 822 through meshing with them. The intermediate teeth 822 then mesh with the internal gear disk 821, driving the internal gear disk 821 to rotate. The internal gear disc 821 meshes with the third drive gear 83 through the meshing groove 823, transmitting power to the third drive gear 83, which ultimately drives the stirring blade assembly 5. This multi-stage gear meshing transmission method reduces unnecessary energy conversion and transmission links, and can flexibly adjust the torque and speed transmitted from the first drive shaft 411 according to the working requirements of the stirring blade assembly 5. When the resistance of the food being stirred is small, a larger transmission ratio is selected, allowing the stirring blade assembly 5 to operate at a higher speed and quickly complete the stirring task; when stirring harder food or encountering greater resistance, the transmission ratio is automatically adjusted to a smaller one, increasing torque output, ensuring that the stirring blade assembly 5 can work normally, reducing energy consumption, and improving the overall performance of the equipment.

[0042] In some embodiments, a base 6 is provided outside the anti-sloping stirring cup 1. The base 6 has at least two hinged edges with first fixing members 61. The main body cover 2 is provided with a second fixing part 231. The first fixing member 61 and the second fixing part 231 are detachably connected. A suction cup structure is provided at the bottom of the base 6. The first and second fixing members can be snap-fit ​​structures or magnetic structures. The suction cup structure can be made of silicone. This embodiment is not specifically limited. Specifically, in this embodiment 1, the second fixing part 231 is disposed on the main body cover 23 of the main body cover 2.

[0043] The following are the operating steps for grinding and firming meat using this meat chopper: The user places the meat to be processed into the mixing chamber 11 of the mixing cup 1, closes the lid 24, and assembles the main unit cover 2 with the mixing cup. The power is then turned on, and the chopper is started. The circuit board assembly 3 controls the motor assembly 4 to rotate forward, driving the blades 511 of the mixing blade assembly 5 to chop the meat. During the chopping process, the current detection device 32 monitors the stability of the rotating blades 51 in real time and feeds the information back to the circuit board assembly 3. The circuit board assembly 3 determines the type of meat based on the feedback information. After a certain chopping time, the timing device 33 sets the clockwise rotation time of the blades 511 based on the characteristics of the meat determined by the current detection device 32. Within the specified time, the blades 511 continue to chop the meat. After the specified time is reached, the circuit board assembly 3 controls the motor assembly 4 to rotate in reverse, causing the back of the blades 512 of the mixing blade assembly 5 to stir and strengthen the chopped meat. After stirring and strengthening is complete, the user turns off the chopper, opens the lid 24, and removes the processed meat, completing the entire meat processing process. It should be noted that the above forward and reverse functions can be reversed.

[0044] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
