Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, specifically to a meat grinder. Background Technology

[0002] Chopping meat by hand is labor-intensive and time-consuming, which is why household meat grinders were developed. A household meat grinder is an electric kitchen tool mainly used for grinding meat and other ingredients such as onions, garlic, and spices. Small household meat grinders have become an essential kitchen appliance for many families, reducing manual labor in the kitchen and providing convenience.

[0003] However, meat grinders still have many drawbacks when in use. For example, when users need to process multiple ingredients, they need to process them in multiple steps, resulting in low processing efficiency. Utility Model Content

[0004] In view of this, the present invention provides a meat grinder to solve the problem that multiple ingredients need to be processed multiple times, and the effect is not good when processing small quantities of ingredients.

[0005] This utility model provides a meat grinder, comprising:

[0006] The control unit includes a motor.

[0007] A meat grinder is connected to one end of the control unit. The meat grinder includes at least two meat grinder structures. Each meat grinder structure includes a meat grinder container and a knife. The knife is disposed inside the meat grinder container and includes a cutting shaft and a blade disposed on the cutting shaft. The cutting shaft of each meat grinder structure is detachably connected to the output shaft of the motor and / or the adjacent cutting shaft. The meat grinder containers of adjacent meat grinder structures are detachably connected to each other and / or the meat grinder containers are detachably connected to the control unit.

[0008] Beneficial effects: By setting the meat grinding unit to include at least two grinding structures, when users have multiple food grinding needs, different foods can be distributed in multiple grinding structures simultaneously, such as vegetables, meat, and seasonings needed for making dumplings. This allows for simultaneous processing of multiple foods at once, resulting in high processing efficiency. Each grinding structure includes a grinding container and blades, enabling each grinding structure to work independently after assembly with the motor. By detachably connecting the blade shaft to the motor's output shaft and / or adjacent blade shafts, and detachably connecting the grinding containers of adjacent grinding structures and / or the grinding containers to the control unit, detachable connections can be achieved between grinding structures and / or between grinding structures and the control unit. Users can freely set the number of working grinding structures according to the amount of food, and freely combine and assemble the grinding structures, resulting in a better user experience.

[0009] In one optional embodiment, one end of the cutter shaft is provided with a first assembly structure and the other end is provided with a second assembly structure, and adjacent cutter shafts are assembled and connected through the first assembly structure and the second assembly structure; the output shaft of the motor is provided with a third assembly structure, and the first assembly structure or the second assembly structure of the cutter shaft is assembled and connected with the third assembly structure on the output shaft.

[0010] In one optional embodiment, the first assembly structure is an assembly hole, the second assembly structure is an assembly shaft; the third assembly structure is an assembly hole, and the second assembly structure connected to it is an assembly shaft; or, the third assembly structure is an assembly shaft, and the first assembly structure connected to it is an assembly hole.

[0011] In one alternative embodiment, the meat grinder container includes:

[0012] The surrounding walls form a receiving cavity with openings at both ends, and the receiving cavity is used to place food ingredients;

[0013] A barrier wall, connected to one end of the peripheral wall, is used to block an opening of the accommodating cavity. The barrier wall has a through hole through which the cutter shaft passes.

[0014] In one optional embodiment, the size of the control unit at the end near the meat grinder is greater than or equal to the size of the other opening of the adjacent meat grinder container, for sealing the other opening of the adjacent meat grinder container;

[0015] And / or, the size of the barrier wall of the meat grinder container is greater than or equal to the size of another opening of the adjacent meat grinder container, for sealing the other opening of the meat grinder container located adjacent to it.

[0016] Beneficial effects: By setting the size of one end of the control unit to be greater than or equal to the size of the other opening of the adjacent meat grinder container, and / or, the size of the barrier wall of the meat grinder container to be greater than or equal to the size of the other opening of the adjacent meat grinder container, the opening of the meat grinder container can be sealed when the control unit is assembled with the meat grinder unit, and / or when adjacent meat grinder structures are assembled, eliminating the need to set a separate sealing wall for the meat grinder container, thus simplifying the overall structure.

[0017] In one alternative embodiment, the outer edge of the barrier wall extends away from the peripheral wall to form a retaining edge, the retaining edge forming a retaining cavity, the retaining cavity being used to enclose the peripheral wall of the adjacent meat grinder container.

[0018] Beneficial effects: By setting a barrier edge on the outer edge of the barrier wall, the barrier edge forms a barrier cavity. When multiple meat grinding structures are connected, the barrier cavity of one meat grinding container can surround the peripheral wall of the adjacent meat grinding containers, preventing multiple meat grinding structures from shaking during the operation of the meat grinder, which would further increase the noise of the meat grinder and affect its normal operation.

[0019] In one alternative embodiment, the meat grinder includes:

[0020] The mounting part is connected to the end of the meat grinder away from the control part. The mounting part is provided with a fixed shaft corresponding to the position of the cutter shaft. The fixed shaft is connected to the mounting hole of the cutter shaft and is perpendicular to the axis of the fixed shaft. The size of the fixed shaft is slightly smaller than the size of the mounting hole.

[0021] Beneficial effects: By setting an installation part at the end of the meat grinder that is away from the control part, and setting a fixed shaft on the installation part, it can be assembled with the mounting hole of the cutter shaft to limit the cutter shaft. At the same time, since the size of the fixed shaft is slightly smaller than the size of the mounting hole along the axial direction perpendicular to the fixed shaft, the fixed shaft can only limit the cutter shaft without affecting the rotation of the cutter shaft, thus ensuring the normal operation of the meat grinder.

[0022] In one alternative embodiment, the meat grinder includes:

[0023] A soundproof part is sleeved on the outside of the meat grinder, and the two ends of the soundproof part are respectively connected to the control part and the mounting part.

[0024] Beneficial effects: Since meat grinders generate noise during operation, by installing a sound insulation part on the outside of the meat grinder, a sound insulation layer can be formed when the meat grinder is working, reducing the noise generated during operation. The two ends of the sound insulation part are respectively assembled and connected to the control part and the installation part, making the sound insulation part more stable. While playing a sound insulation role, it will not shake, ensuring the sound insulation effect.

[0025] In one alternative embodiment, the sound insulation part is a retractable structure adapted to fit the meat grinder part.

[0026] Beneficial effects: Since users can freely set the number of meat grinding structures according to actual needs, the overall size of the meat grinding section will change. By setting the sound insulation section as a retractable structure, the sound insulation section can be adjusted to match the size of the meat grinding section no matter how the size changes, so as to ensure the sound insulation effect.

[0027] In one optional embodiment, the sound insulation part includes at least two sound insulation sections with different volumes, and adjacent sound insulation sections are slidably connected to achieve the expandability of the sound insulation part.

[0028] Beneficial effects: By setting the sound insulation section to include at least two sound insulation subsections with different volumes, and allowing adjacent sound insulation subsections to slide and connect, the smaller sound insulation subsection can be housed in the larger sound insulation subsection or stretched out from the larger sound insulation subsection when it shrinks, thereby achieving the stretchability of the sound insulation section and making the structure relatively simple.

[0029] In one optional embodiment, one end of the sound insulation section is provided with a first limiting structure and the other end is provided with a second limiting structure. The first limiting structure and the second limiting structure of adjacent sound insulation sections are connected in cooperation to fix the adjacent sound insulation sections after the sound insulation section is extended and retracted into place.

[0030] Beneficial effects: By setting a first limiting structure and a second limiting structure at both ends of the sound insulation section, adjacent sound insulation sections can be connected by the cooperation of the first limiting structure and the second limiting structure, so that when the sound insulation section is stretched to the required size, it can maintain the corresponding position, ensuring the stability of the sound insulation section, and thus ensuring the sound insulation effect.

[0031] In one alternative embodiment, the meat grinder structure is provided in three parts;

[0032] And / or, at least two of the meat grinder structures are arranged vertically;

[0033] And / or, the meat grinding containers of at least two of the meat grinding structures have different volumes.

[0034] Beneficial effects: Meat grinders have limited capacity requirements for ingredients. If too much or too little food is placed in the fixed-volume grinding container, it will affect the grinding effect of the meat grinder. Therefore, by setting different volumes of the grinding structure, users can choose the appropriate size grinding structure according to the amount and volume of the ingredients, so that the grinding structure can better match the ingredients and achieve the best grinding effect of the blades, thus improving the user experience.

[0035] In one alternative implementation, the motor is a permanent magnet DC motor.

[0036] Beneficial effects: By setting the motor to a permanent magnet DC motor, the motor can automatically adjust the output torque according to the amount of food, so as to achieve the required churning effect. The structure is relatively simple. Attached Figure Description

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0048] Chopping meat by hand is labor-intensive and time-consuming, which is why household meat grinders were developed. A household meat grinder is an electric kitchen tool mainly used for grinding meat and other ingredients such as onions, garlic, and spices. Small household meat grinders have become an essential kitchen appliance for many families, reducing manual labor in the kitchen and providing convenience.

[0049] However, meat grinders still have many drawbacks when in use. For example, when users need to process multiple ingredients, they need to process them in multiple steps, resulting in low processing efficiency.

[0050] To address this, a meat grinder has been disclosed, comprising multiple nested bowls arranged in a nested doll-like configuration. During use, ingredients can be placed into the bowls for separate processing. However, this meat grinder requires the upper ends of the bowls to be fastened into the sockets at the bottom of the machine head housing during operation. The support blade extends downwards into the corresponding bowls, allowing the bottom fixing blocks to be stably fitted onto the outer sides of the positioning shafts of the different bowls. When the control button is pressed, the main motor rotates under the control of the main control board, which in turn drives the cutting blades to rotate inside the bowls to perform the cutting operation. Therefore, this meat grinder can only operate multiple bowls simultaneously and cannot be freely adjusted according to actual needs, resulting in a poor user experience.

[0051] The following is combined with Figures 1 to 4 The following describes embodiments of the present invention.

[0052] According to an embodiment of the present invention, a meat grinder is provided, comprising:

[0053] Control unit 1, which contains motor 103;

[0054] The meat grinding unit 2 is connected to one end of the control unit 1. The meat grinding unit 2 includes at least two meat grinding structures 201. Each meat grinding structure 201 includes a meat grinding container 2011 and a blade 2012. The blade 2012 is disposed inside the meat grinding container 2011. The blade 2012 includes a blade shaft 20121 and a blade 20122 disposed on the blade shaft 20121. The blade shaft 20121 of each meat grinding structure 201 is detachably connected to the output shaft of the motor 103 and / or the adjacent blade shaft 20121. The meat grinding containers 2011 of adjacent meat grinding structures 201 are detachably connected to each other and / or the meat grinding containers 2011 are detachably connected to the control unit 1.

[0055] By configuring the meat grinder 2 to include at least two meat grinder structures 201, when a user has multiple food grinding needs, different food ingredients can be distributed in multiple meat grinder structures 201 simultaneously, such as vegetables, meat, and seasonings needed for making dumplings. This allows for simultaneous processing of multiple food ingredients at one time, resulting in high processing efficiency. Each meat grinder structure 201 includes a meat grinder container 2011 and a blade 2012, allowing each meat grinder structure 201 to work independently after being assembled with the motor 103. By detachably connecting the blade shaft 20121 to the output shaft of the motor 103 and / or adjacent blade shafts 20121, and detachably connecting the meat grinder containers 2011 of adjacent meat grinder structures 201 to each other and / or between the meat grinder containers 2011 and the control unit 1, detachable connections can be achieved between the meat grinder structures 201 and / or between the meat grinder structures 201 and the control unit 1. Users can freely set the number of working meat grinder structures 201 according to the amount of food ingredients and freely combine and assemble the meat grinder structures 201, resulting in a better user experience.

[0056] like Figure 1 As shown, the meat grinding structure 201 in this embodiment has three parts. As an alternative implementation, the meat grinding structure 201 may also have two, four, or more parts; no further restrictions are imposed here.

[0057] In this embodiment, the three meat grinding structures 201 are arranged vertically. As an alternative implementation, the three meat grinding structures 201 may also be arranged horizontally. In this embodiment, the control unit 1 of the meat grinder is also preferably arranged horizontally.

[0058] The uppermost meat grinding structure 201 is detachably connected to the control unit 1, and the other meat grinding structures 201 are detachably connected to each other. The blade shaft 20121 of the uppermost meat grinding structure 201 is detachably connected to the output shaft of the motor 103, and the blade shaft 20121 of the other meat grinding structures 201 is detachably connected to the adjacent blade shaft 20121.

[0059] In this embodiment, the three meat-grinding structures 201 have different volumes. As an alternative implementation, multiple meat-grinding structures 201 may have the same volume. In this case, the volume of the meat-grinding structure 201 can be set appropriately to better accommodate ingredients of different sizes.

[0060] The meat grinder has limited capacity requirements for the amount of food it can hold. If too much or too little food is placed in the fixed-volume meat grinder container 2011, it will affect the grinding effect of the meat grinder. Therefore, by setting different volumes of the meat grinder structure 201, users can select the appropriate size meat grinder structure 201 according to the amount and volume of food, so that the meat grinder structure 201 can better match the food and achieve the best grinding effect of the blade 2012, thus improving the user experience.

[0061] The meat grinding structure 201 has a meat grinding container 2011 and a blade 2012 arranged in a one-to-one correspondence. As an alternative implementation, a meat grinding container 2011 may contain multiple blades 2012.

[0062] Specifically, the volume of the meat grinding container 2011 of different meat grinding structures 201 is different, and the size of the blade 2012 of different meat grinding structures 201 is different.

[0063] From top to bottom, the volume of the meat grinding structure 201 increases, and the blades 2012 of the meat grinding structure 201 also increase in size. This ensures the stability of the meat grinding structure 201 assembly and simplifies the overall structure of the meat grinder. Alternatively, from top to bottom, the volume of the meat grinding structure 201 decreases, and the blades 2012 of the meat grinding structure 201 decrease in size. In this case, additional structures are required to ensure the overall stability of the meat grinder.

[0064] In one embodiment, one end of the cutter shaft 20121 is provided with a first assembly structure and the other end is provided with a second assembly structure. Adjacent cutter shafts 20121 are connected by the first assembly structure and the second assembly structure. The output shaft of the motor 103 is provided with a third assembly structure. The first assembly structure or the second assembly structure of the cutter shaft 20121 is connected by the third assembly structure on the output shaft.

[0065] Specifically, the first assembly structure is an assembly hole, and the second assembly structure is an assembly shaft; the third assembly structure is an assembly hole, and the second assembly structure connected to it is an assembly shaft; or, the third assembly structure is an assembly shaft, and the first assembly structure connected to it is an assembly hole. As a possible implementation, the first assembly structure may be an assembly shaft, the second assembly structure may be an assembly hole, and the third assembly structure may be either an assembly shaft or an assembly hole.

[0066] like Figure 2 As shown, in this embodiment, the meat grinding container 2011 of each meat grinding structure 201 includes:

[0067] The surrounding wall 20111 forms a accommodating cavity with openings at both ends, and the accommodating cavity is used to place food ingredients;

[0068] The barrier wall 20112 is connected to one end of the peripheral wall 20111 and is used to block an opening of the accommodating cavity. The barrier wall 20112 is provided with a through hole 201121, and the cutter shaft 20121 passes through the through hole 201121.

[0069] By setting the meat grinder container 2011 to include a peripheral wall 20111 and a barrier wall 20112, the structure of the meat grinder container 2011 is relatively simple.

[0070] In one embodiment, the size of the end of the control unit 1 near the meat grinder 2 is greater than or equal to the size of another opening of the adjacent meat grinder container 2011, for blocking the other opening of the meat grinder container 2011 disposed adjacent to it;

[0071] The size of the barrier wall 20112 of the meat grinder container 2011 is greater than or equal to the size of another opening of the adjacent meat grinder container 2011, and is used to block the other opening of the meat grinder container 2011 that is located next to it.

[0072] By setting the size of one end of the control unit 1 to be greater than or equal to the size of the other opening of the adjacent meat grinder container 2011, and / or setting the size of the barrier wall 20112 of the meat grinder container 2011 to be greater than or equal to the size of the other opening of the adjacent meat grinder container 2011, the opening of the meat grinder container 2011 can be sealed when the control unit 1 is assembled with the meat grinder 2, and / or when adjacent meat grinder structures 201 are assembled, eliminating the need to set a separate sealing wall for the meat grinder container 2011, thus simplifying the overall structure.

[0073] Of course, in other embodiments, it is also possible to limit the size of the end of the control unit 1 near the meat grinder 2 to be greater than or equal to the size of the other opening of the adjacent meat grinder container 2011, for sealing the other opening of the adjacent meat grinder container 2011, such as when only one meat grinder structure 201 adjacent to the control unit 1 is provided; or, it is possible to limit the size of the barrier wall 20112 of the meat grinder container 2011 to be greater than or equal to the size of the other opening of the adjacent meat grinder container 2011, for sealing the other opening of the adjacent meat grinder container 2011, which can be used as a way to connect multiple meat grinder structures 201; or, it is possible not to limit the size of the end of the control unit 1 near the meat grinder 2, not to limit the size of the barrier wall 20112 of the meat grinder container 2011, but to use a separate structure to seal the other opening of the meat grinder container 2011.

[0074] Since the three meat-grinding structures 201 in this embodiment can be stacked in the vertical direction, the other opening of the meat-grinding container 2011 is the top opening. The barrier wall 20112 of the meat-grinding container 2011 refers to the bottom wall of the meat-grinding container 2011. When multiple meat-grinding structures 201 are used in combination, the bottom wall of the upper meat-grinding structure 201 serves as the cover plate for the top opening of the lower meat-grinding structure 201.

[0075] It should be noted that in other embodiments, the meat grinder container 2011 may also include a peripheral wall 20111, a barrier wall 20112, and a top wall, wherein the top wall is a separately provided cover plate that seals the top opening.

[0076] like Figure 2As shown, the outer edge of the barrier wall 20112 extends away from the peripheral wall 20111 and has a retaining edge 201122. The retaining edge 201122 forms a retaining cavity, and the peripheral wall 20111 of the adjacent meat grinder container 2011 is used to enclose the cavity.

[0077] By setting a retaining edge 201122 on the outer edge of the barrier wall 20112, the retaining edge 201122 forms a retaining cavity. When multiple meat grinding structures 201 are connected, the retaining cavity of one meat grinding container 2011 can surround the peripheral wall 20111 of the adjacent meat grinding container 2011, preventing multiple meat grinding structures 201 from shaking when the meat grinder is working, which would further increase the noise of the meat grinder and affect the normal operation of the meat grinder.

[0078] Specifically, a fence edge 201122 is provided, arranged in a ring shape, and can be integrally formed with the barrier wall 20112. As an alternative implementation, the fence edge 201122 and the barrier wall 20112 can also be separately provided and then fixedly connected in other ways; no further restrictions are placed here. As an alternative implementation, multiple fence edges 201122 can also be provided at intervals along the circumference, and multiple fence edges 201122 together form a ring structure, forming a fence cavity.

[0079] As an alternative implementation, the outer edge of the barrier wall 20112 may not be provided with a retaining edge 201122.

[0080] When a meat grinder uses multiple meat grinding structures 201 to grind meat simultaneously, in order to further stabilize adjacent meat grinding structures 201 and prevent them from shaking, a fixing structure can be set between adjacent meat grinding structures 201. For example, a buckle can be set on the peripheral wall 20111 of one meat grinding container 2011, and a locking hole can be set on the perimeter 201122 of another meat grinding container 2011. Alternatively, a buckle can be set on the peripheral wall 20111 of one meat grinding container 2011, and a locking hole can be set on the peripheral wall 20111 of another meat grinding container 2011, etc. Specifically, in order to prevent the food inside the meat grinding container 2011 from falling out of the locking hole, a small bracket can be set on the outer side of the peripheral wall 20111 of the meat grinding container 2011, and a locking hole can be set on the small bracket to fix the adjacent meat grinding structures 201 together.

[0081] When a meat grinder uses a meat grinding structure 201 for grinding, in order to ensure that the meat grinding container 2011 does not shake, a fixing structure can be set between the meat grinding structure 201 and the control unit 1. For example, a buckle can be set on the peripheral wall 20111 of one meat grinding container 2011, and a locking hole can be set on the perimeter edge 201122 of the other meat grinding container 2011, or a buckle can be set on the peripheral wall 20111 of one meat grinding container 2011, and a locking hole can be set on the peripheral wall 20111 of the other meat grinding container 2011, etc., so as to fix the meat grinding structure 201 and the control unit 1.

[0082] Of course, in other embodiments, a fixed structure may not be required.

[0083] like Figure 1 As shown, the meat grinder includes:

[0084] Mounting part 3 is connected to the end of meat grinder 2 away from control part 1. Mounting part 3 is provided with fixed shaft 301 at the position corresponding to cutter shaft 20121. Fixed shaft 301 is connected to the mounting hole of cutter shaft 20121 and is arranged in an axial direction perpendicular to fixed shaft 301. The size of fixed shaft 301 is slightly smaller than the size of mounting hole.

[0085] By providing a mounting part 3 at the end of the meat grinder 2 away from the control part 1, and providing a fixed shaft 301 on the mounting part 3, it can be assembled with the mounting hole of the cutter shaft 20121 to limit the movement of the cutter shaft 20121. At the same time, since the size of the fixed shaft 301 is slightly smaller than the size of the mounting hole along the axial direction perpendicular to the fixed shaft 301, the fixed shaft 301 can only limit the movement of the cutter shaft 20121 without affecting the rotation of the cutter shaft 20121, thus ensuring the normal operation of the meat grinder.

[0086] like Figure 1 As shown, mounting part 3 is the bottom wall of the meat grinder.

[0087] As an alternative implementation, the meat grinder may not include the mounting part 3. Instead, the barrier wall 20112 of the lowest meat grinding structure 201 may be used as the bottom wall of the entire meat grinder. In this case, a plug may be installed at the through hole 201121 of the barrier wall 20112 to block the through hole 201121 and prevent food from falling out.

[0088] like Figure 1 and Figure 3 As shown, the meat grinder includes:

[0089] The sound insulation part 4 is sleeved on the outside of the meat grinder part 2, and the two ends of the sound insulation part 4 are respectively connected to the control part 1 and the mounting part 3.

[0090] Since the meat grinder generates noise during operation, a sound insulation part 4 is installed on the outside of the meat grinding part 2 to form a sound insulation layer when the meat grinder is working, thereby reducing the noise generated during operation. The two ends of the sound insulation part 4 are respectively assembled and connected to the control part 1 and the mounting part 3, making the sound insulation part 4 more stable. While playing a sound insulation role, it will not shake, thus ensuring the sound insulation effect.

[0091] As an alternative implementation, the meat grinder may not include the sound insulation part 4.

[0092] In one embodiment, the sound insulation part 4 is a retractable structure adapted to fit the meat grinder part 2.

[0093] Since users can freely set the number of meat grinding structures 201 according to actual needs, the overall size of the meat grinding section 2 will change. By setting the sound insulation section 4 as a retractable structure, the sound insulation section 4 can be adjusted to match the size of the meat grinding section 2 no matter how the size changes, so as to ensure the sound insulation effect.

[0094] As an alternative implementation, the sound insulation part 4 may be a non-stretchable structure. Since the number of meat grinding structures 201 may vary in actual use, a sound insulation part 4 with the same number of meat grinding structures 201 may be provided to adapt to the size of different combinations of meat grinding structures 201 in order to match the size of the meat grinding part 2. Alternatively, the sound insulation part 4 may include multiple detachably connected sound insulation structures, with each sound insulation structure corresponding to a meat grinding structure 201.

[0095] In this embodiment, the sound insulation section 4 includes three sound insulation subsections 401 with different volumes. Adjacent sound insulation subsections 401 can be slidably connected to each other to achieve the expandability of the sound insulation section 4.

[0096] By configuring the sound insulation section 4 to include three sound insulation subsections 401 with different volumes, and allowing adjacent sound insulation subsections 401 to slide together, the smaller sound insulation subsection 401 can be housed in the larger sound insulation subsection 401 or stretched out from the larger sound insulation subsection 401 when it is contracted, thereby achieving the stretchability of the sound insulation section 4, which has a relatively simple structure.

[0097] As an alternative implementation, the sound insulation section 4 may include other numbers of sound insulation subsections 401. The number of sound insulation subsections 401 may correspond one-to-one with the number of meat grinder structures 201, or they may not correspond one-to-one, as long as the size of the extended sound insulation section 4 is adapted to the size of the meat grinder section 2.

[0098] In order to maintain a fixed connection between adjacent sound insulation sections 401, one end of the sound insulation section 401 is provided with a first limiting structure 4011 and the other end is provided with a second limiting structure 4012. The first limiting structure 4011 and the second limiting structure 4012 of adjacent sound insulation sections 401 are connected in cooperation to fix the adjacent sound insulation sections 401 after the sound insulation section 4 is extended and retracted into place.

[0099] By setting a first limiting structure 4011 and a second limiting structure 4012 at both ends of the sound insulation section 401, adjacent sound insulation sections 401 can be connected by the first limiting structure 4011 and the second limiting structure 4012, so that the sound insulation section 4 can maintain the corresponding position when it is stretched to the required size, ensuring the stability of the sound insulation section 4 and thus ensuring the sound insulation effect.

[0100] like Figure 4 As shown, the first limiting structure 4011 is a buckle, and the second limiting structure 4012 is a locking hole. As an alternative implementation, the first limiting structure 4011 may be a locking hole, the second limiting structure 4012 may be a buckle, or the first limiting structure 4011 and the second limiting structure 4012 may be other compatible forms, such as protrusions and grooves.

[0101] As an alternative implementation, the sound insulation sections 401 may not have a limiting structure between them. Instead, the position of two adjacent sound insulation sections 401 may be limited by friction. Alternatively, the sound insulation sections 401 may be limited by their own material at different positions.

[0102] In this embodiment, the sound insulation part 4 is specifically a sound insulation cover, which is a retractable structure. When using a meat grinder, it can be directly covered on the outside of the meat grinder 2. Its upper edge contacts and cooperates with the bottom wall of the control part 1, and its lower edge contacts and cooperates with the mounting part 3.

[0103] like Figure 3 As shown, the shape of the sound insulation part 4 matches the shape of the meat grinder part 2, specifically a frustum shape with one end smaller than the other. As an alternative implementation, the specific shape of the sound insulation part 4 may not be limited; it may be a cylindrical structure or other shapes.

[0104] Of course, in other embodiments, the connection relationship between the sound insulation part 4 and the control part 1 and the mounting part 3 may not be specifically limited. The upper and lower ends of the sound insulation part 4 may be snapped into the control part 1 and the mounting part 3, or other limiting connections may be made, etc. No further restrictions are imposed here.

[0105] In one embodiment, to further enhance the sound insulation effect, a sound-absorbing coating may also be provided on the inner wall of the sound insulation part 4. As an alternative implementation, the sound insulation part 4 may not have a sound-absorbing coating provided inside.

[0106] In one embodiment, motor 103 is a permanent magnet DC motor.

[0107] By setting the motor 103 as a permanent magnet DC motor, the motor 103 can automatically adjust the output torque according to the amount of food to achieve the required churning effect, and the structure is relatively simple.

[0108] The permanent magnet DC motor incorporates a current sensor and a microcontroller. The current sensor detects the current in the motor 103, while the microcontroller reads the data from the current sensor and uses a PID control algorithm to calculate the error by comparing the actual current with the set current. It then adjusts the voltage of the motor 103 accordingly and sends the calculated control signal to the driver of the motor 103 to adjust the output power in a timely manner to maintain the desired current. In this way, when the load increases (e.g., when handling tough meat or processing a large amount of food), the current loop detects the increase and adjusts the voltage of the motor 103 accordingly to provide more torque. The permanent magnet DC motor can automatically adjust its power to adapt to load changes. This method not only improves the stability and reliability of the system but also enhances its overall performance.

[0109] When the food processing in the meat grinder is finished, because the food has adhered to the wall, the load on the grinder blades is almost negligible, and the current at this time is the no-load current. When the no-load current is detected for a preset judgment time, such as 5 seconds, the system determines that processing is complete and automatically cuts off the power, stopping motor 103 to avoid no-load operation affecting product lifespan. As an alternative implementation, the preset judgment time could be 10 seconds, or other values; no further restrictions are imposed here.

[0110] In other embodiments, motor 103 may also be a series-wound DC motor, but the speed regulation of a series-wound DC motor is not precise enough. In this case, additional circuitry and controllers are required to achieve precise speed and power control.

[0111] like Figure 1 As shown, the control unit 1 includes, from top to bottom, a control button 101, a push-button switch 102, and a motor 103. In use, the user can press the control button 101 to turn the push-button switch 102 on or off, thereby turning the meat grinder on, off, or paused as needed.

[0112] The meat grinder in this embodiment, on the one hand, features a multi-layer design that allows for the simultaneous processing of multiple ingredients through the combination of different grinding structures 201, achieving different chopping effects for different ingredients, thereby reducing processing time while improving chopping efficiency. Simultaneously, through a wide-range adjustable power permanent magnet DC motor and an automatic control system, the meat grinder can automatically adjust the power of the motor 103 according to the load of the ingredients, further enhancing the intelligence of the meat grinder and reducing the learning curve for users in cooking.

[0113] In this embodiment, the meat grinder can also reduce the negative impact of noise on the user by using the outermost sound insulation part 4 when the user is using the meat grinder.

[0114] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the appended claims.
