[0051] In related technologies, small household meat grinders typically use a button on the top to control a drive that rotates the blades, cutting food into particles such as meat, vegetables, or garlic. These grinders require users to continuously press the button and estimate the cutting effect by adjusting the cutting time, or by opening the lid to check the results. If the cutting effect is unsatisfactory, the only solution is to increase the button pressing time, i.e., increase the cutting time, to improve the cutting effect. This control scheme not only requires users to spend a significant amount of time operating the grinder but also cannot guarantee that the final food particles will meet their actual needs.

[0052] In one embodiment, such as Figure 1 As shown, a meat grinder is provided, including: a first body 100, a second body 200, a controller 110, an interaction component 120, a drive component 130 and an image acquisition component 140 disposed on the first body 100, and a transmission component 210, a first blade assembly 220 and a second blade assembly 230 disposed on the second body 200.

[0053] In this embodiment, the meat grinder is divided into two parts: a first body 100 and a second body 200, which are detachably connected. In practical application, the first body 100 houses a controller 110, a drive assembly 130, and an image acquisition assembly 140. An interaction assembly 120 is located on the surface of the first body 100. The second body 200 houses a detachable transmission assembly 210, a first blade assembly 220, and a second blade assembly 230. It should be noted that the controller 110, drive assembly 130, and image acquisition assembly 140 inside the first body 100, and the interaction assembly 120 on the surface of the second body 200, are all standard configurations, requiring disassembly of the first body 100 for movement. The transmission assembly 210, the first blade assembly 220, and the second blade assembly 230 inside the second body 200 can all be individually disassembled for cleaning.

[0054] In this embodiment, the second body 200 includes a receiving cavity for placing the food to be cut and processed. It should be noted that this embodiment does not limit the specific type of food; the food to be cut and processed can be meat, vegetables, or other foods suitable for cutting and processing by a small meat grinder.

[0055] In this embodiment, the controller 110 is connected to the interaction component 120, the drive component 130, and the image acquisition component 140. The controller 110 can transmit data and commands to the interaction component 120, the drive component 130, and the image acquisition component 140 respectively. After the meat grinder is powered on, the controller 110 generates corresponding control parameters based on the operation commands of the interaction component 120, and controls the meat grinder to start cutting and processing according to the control parameters. The controller 110 sends corresponding drive signals, such as voltage signals, current signals, or PWM signals, to the drive component 130 to output corresponding power signals, driving the transmission component 210 to rotate. After receiving the operation commands from the interaction component 120, the controller 110 sends corresponding image acquisition signals to the image acquisition component 140, so that the image acquisition component 140 continuously acquires the status images of the food in the accommodating cavity of the second body 200 at a certain time period, and receives the status images sent by the image acquisition component 140 and performs corresponding recognition processing.

[0056] In this embodiment, as Figure 2 As shown, the drive assembly 130 and the transmission assembly 210 are detachably connected. The first blade assembly 220 is disposed on the side of the transmission assembly 210, and the second blade assembly 230 is disposed at the end of the transmission assembly 210 away from the drive assembly 130.

[0057] In this embodiment, the transmission assembly 210 includes at least a rotating shaft and a tool holder, with the tool holder arranged around the rotating shaft. The rotating shaft of the transmission assembly 210 is connected to the drive assembly 130, which drives the rotating shaft to rotate and thus rotates the tool holder.

[0058] In this embodiment, the first blade assembly 220 includes a predetermined number of cutting blades. For example... Figure 3 As shown, the first blade assembly 220 includes multiple sets of crescent-shaped cutting blades. It should be noted that the number and specific shape of the cutting blades can be configured according to the needs of the actual application scenario, and are not specifically limited here. In practical applications, the cutting blades of the first blade assembly 220 can be directly fitted onto the rotating shaft of the transmission assembly 210. That is, a hole corresponding to the shape of the shaft is opened in the connecting part (middle area or end area) of the blade, and the rotating shaft passes through the hole and the blade is fixed on both sides of the blade using a tool holder or other fixing components to fix the blade's position. The first blade assembly 220 can also be directly embedded in the tool holder of the transmission assembly 210, with the connecting part of the blade directly inserted into the pre-reserved embedding hole of the tool holder. The first blade assembly 220 can also be an integral structure with the tool holder. It should be noted that the first blade assembly 220 can be mounted on the transmission assembly 210 using any assembly and setting method in related technologies. The first blade assembly 220 is disposed on the side of the transmission assembly 210. When the transmission assembly 210 drives the first blade assembly 220 to rotate, the first blade assembly 220 is used to cut the food placed in the internal cavity of the second body 200.

[0059] The second blade assembly 230 includes an L-shaped blade structure. The distance between the bottom surface of the L-shaped blade structure and the bottom of the internal cavity of the second body 200 is less than a preset distance, so as to agitate food scraps at the bottom of the internal cavity of the second body 200 through the bottom surface of the L-shaped blade structure. The distance between the vertical surface of the L-shaped blade structure and the side surface of the internal cavity of the second body 200 is less than a preset distance, so as to scrape off food scraps from the side surface of the internal cavity of the second body 200 through the vertical surface of the L-shaped blade structure. In one embodiment, the L-shaped blade structure can be made of rubber or elastic plastic. It should be noted that using rubber or elastic plastic for the second blade structure allows the bottom surface and vertical surface of the L-shaped blade structure to directly contact the inner wall of the internal cavity of the second body 200, avoiding scratching or damaging the second body 200. In practical applications, the second body 200 can be a glass bowl. It should be noted that the material of the second body 200 can be configured according to the needs of the actual application scenario, and is not specifically limited here.

[0060] In practical applications, the first body 100 and the second body 200 are detachably connected. When the first body 100 and the second body 200 are connected, the drive assembly 130 and the transmission assembly 210 are also connected. When the first body 100 and the second body 200 are separated, the drive assembly 130 and the transmission assembly 210 are also separated. In this embodiment, when the first body 100 and the second body 200 are connected, the bodies of the first body 100 and the second body 200 form a sealed space, thereby preventing food from splashing out of the internal cavity of the second body 200 during food cutting and processing.

[0061] In this embodiment, the meat grinder can perform the food cutting and processing process according to the following device interaction logic:

[0062] First, the user operates the interaction component 120, causing the interaction component 120 to generate corresponding operation instructions and send the operation instructions to the controller 110. The controller 110 generates target control parameters based on the operation instructions from the interaction component 120, wherein the target control parameters include target granularity and target current.

[0063] Then, the controller 110 controls the drive assembly 130 to drive the transmission assembly 210 to rotate according to the target current. The transmission assembly 210 drives the first blade assembly 220 and the second blade assembly 230 to rotate. When the first blade assembly 220 rotates, it is used to cut the food in the internal cavity of the second body 200. When the second blade assembly 230 rotates, it is used to stir the food at the bottom of the internal cavity of the second body 200.

[0064] While the controller 110 controls the drive assembly 130 to drive the transmission assembly 210 to rotate according to the target current, the image acquisition assembly 140 is used to capture the status image of the food in the internal cavity of the second body 200 and send the status image to the controller 110.

[0065] Finally, the controller 110 obtains the actual granularity based on the status image and compares the target granularity with the actual granularity. If the actual granularity equals the target granularity, the control drive component 130 stops.

[0066] In this embodiment, the controller 110 has a built-in image analysis and recognition algorithm, which is used to analyze and identify the type and particle size of the food placed in the internal cavity of the second body 200 based on the state image. It should be noted that the image analysis and recognition algorithm can use algorithms from related technologies, which will not be elaborated here.

[0067] In summary, this embodiment provides a meat grinder. After the user sets the control parameters of the meat grinder through the interaction component 120, the interaction component 120 sends the operation command to the controller 110. The controller 110 obtains the target control parameters according to the operation command and controls the drive component 130 to drive the transmission component 210 to rotate according to the target control parameters. The controller also controls the image acquisition component 140 to acquire the state image of the food inside the internal cavity of the second body 200. When the transmission component 210 rotates, the first blade assembly 220 completes the cutting and processing of the food, and the second blade assembly 230 at least stirs up the food at the bottom of the internal cavity to ensure that the first blade assembly 220 can fully cut the food, thus ensuring the cutting and processing effect of the meat grinder. When the actual particle size obtained by the controller 110 through the state image is equal to the target particle size, the controller controls the drive component 130 to stop, thus completing the cutting and processing of the food. The meat grinder provided in this embodiment can automatically start, cut, ensure cutting effect, and stop according to operation instructions, thus realizing fully automatic processing of meat grinding and cutting, greatly improving the ease of use and processing reliability of the meat grinder.

[0068] In one embodiment, such as Figure 3 and Figure 5 As shown, the second blade assembly 230 includes a bottom blade and a side blade. The bottom blade has a corresponding opening at its connecting portion, allowing the second blade assembly 230 to be fitted into the end of the transmission assembly 210. When the transmission assembly 210 rotates, it drives the bottom blade and the side blade to rotate as well.

[0069] The second blade assembly 230 is used to stir the food at the bottom of the internal chamber of the second body 200 by the bottom blade and to scrape the food off the sides of the internal chamber of the second body 200 by the side blade.

[0070] In this embodiment, the bottom blade and the side blade can be an integral structure. Alternatively, one end of the bottom blade and one end of the side blade can be welded together. It should be noted that the connection method of the bottom blade and the side blade can be configured according to the needs of the actual application scenario. When the second blade assembly 230 rotates, the bottom blade and the side blade rotate synchronously, that is, the bottom blade and the side blade rotate simultaneously in the same direction and at the same speed according to the force provided by the transmission assembly 210.

[0071] In this embodiment, the bottom blade agitates the food at the bottom of the internal cavity of the second body 200 during rotation, preventing food debris from adhering to the bottom of the internal cavity. The side blades scrape off food from the sides of the internal cavity of the second body 200 during rotation, also preventing food debris from adhering to the sides of the internal cavity. The arrangement of the bottom and side blades effectively ensures that food debris does not adhere to the inner wall of the second body 200, allowing the meat grinder to fully cut and process the food.

[0072] It should be noted that the second blade assembly 230 at least tumbles the food at the bottom of the internal cavity of the second body 200 because no matter how the first blade assembly 220 cuts and processes the food, the food will first fall to the bottom of the internal cavity of the second body 200. Therefore, in this embodiment, the second blade assembly 230 must at least ensure that the food at the bottom of the internal cavity is tumbled to the cutting and processing area of ​​the first blade assembly 220.

[0073] In one embodiment, such as Figure 4 As shown, the bottom blade includes multiple protruding structures.

[0074] In this embodiment, by setting a preset number of protrusions on the bottom blade, the bottom blade is made into a serrated shape, which can ensure that the food scraps at the bottom of the internal chamber are thoroughly mixed, thereby improving the cutting and processing effect of the meat grinder.

[0075] In one embodiment, the shape of the protrusion structure can be a triangular protrusion, a trapezoidal protrusion, an elliptical protrusion, or an irregular protrusion, and the shape of the protrusion structure can be configured according to the needs of the actual application scenario.

[0076] In one embodiment, the side blade includes multiple protrusions.

[0077] In this embodiment, by providing a protruding structure on the side blade, the food scraps adhering to the side of the internal cavity of the second body 200 can be effectively removed by the side blade.

[0078] Optionally, the distance between the protruding structure on the side blade and the bottom of the internal cavity of the second body 200 is less than a preset distance threshold. In this embodiment, by providing a protruding structure on the side blade near the bottom of the internal cavity, it can work in conjunction with the protruding structure on the bottom blade to further improve the mixing effect of food scraps at the bottom of the internal cavity, thereby improving the cutting and processing effect of the meat grinder.

[0079] In one embodiment, the second blade assembly 230 is made of an elastic material, including rubber or soft plastic. In this embodiment, by using an elastic material to make the second blade assembly 230, it can directly contact the inner wall of the internal cavity of the second body 200, thereby maximizing the tumbling and scraping effects of the second blade assembly 230.

[0080] In one embodiment, such as Figure 5 As shown, the meat grinder also includes a reduction gear set disposed on the second body 200, which is located at the end of the transmission assembly 210 away from the drive assembly 130. The second blade assembly 230 is connected to the transmission assembly 210 via the reduction gear set. The reduction gear set is used to reduce the rotational speed of the second blade assembly 230 according to a preset reduction ratio, wherein the rotational speed of the second blade assembly 230 is less than the rotational speed of the first blade assembly 220.

[0081] In this embodiment, the reduction gear set consists of multiple gears that transmit power through meshing. When one gear rotates, it drives another gear meshing with it to rotate. The core function of the reduction gear set is to reduce the rotational speed and increase the torque by using gears of different sizes. In practical applications, a smaller gear (driving gear) can drive a larger gear (driven gear) to achieve the speed reduction effect.

[0082] The reduction ratio of a reduction gear set refers to the ratio of the input gear speed to the output gear speed. It can also be calculated using the number of teeth on the gears, i.e., reduction ratio = number of teeth on the input gear / number of teeth on the output gear.

[0083] In this embodiment, the second blade assembly 230 is connected to the transmission assembly 210 via a reduction gear set, which ensures that the rotational speed of the second blade assembly 230 is lower than that of the first blade assembly 220 throughout the meat grinder process, and ensures that the rotational speed of the second blade assembly 230 is always in a low-speed rotational state, so as to ensure the scraping and tumbling effect of the second blade assembly 230.

[0084] In this embodiment, the rotational speed output by the motor directly acts on the shaft of the transmission assembly 210, driving the first blade assembly 220 to cut and process the food. Simultaneously, the rotational speed is transmitted to the second blade assembly 230, which operates on the same shaft, via a reduction gear set. Figure 5 As shown, the second blade assembly 230 rotates along the inner wall of the second body 200, which can scrape off the food inside the second body 200.

[0085] In one embodiment, the meat grinder further includes a current detection component disposed on the first body 100, which is connected to both the drive component 130 and the controller 110. The current detection component detects the actual current of the drive component 130 and sends the actual current to the controller 110. The controller 110 adjusts the output power of the drive component 130 based on the difference between the actual current and the target current, so that the actual current equals the target current.

[0086] In this embodiment, the current detection component can use devices, chips, or integrated circuits that can detect real-time current, such as current sensors or current detection circuits.

[0087] This embodiment is based on a PID control algorithm. By comparing the actual current and the target current, the difference between the actual current and the target current is calculated. The drive voltage of the drive component 130 is adjusted according to this difference. The controller 110 sends a drive control signal corresponding to this drive voltage to the motor driver, adjusting the output power of the motor driver as needed to keep the actual current equal to the target current. Based on these steps, when the meat grinder is mixing ingredients, it adaptively adjusts the output power of the motor driver according to the quantity and size of the ingredients to ensure effective cutting and processing.

[0088] In one embodiment, the drive assembly 130 includes a motor driver and a permanent magnet DC motor. The motor driver is connected to both the controller 110 and the permanent magnet DC motor, and the permanent magnet DC motor is detachably connected to the transmission assembly 210. A current detection assembly is connected to the permanent magnet DC motor and is used to detect the actual current of the permanent magnet DC motor. The controller 110 adjusts the output power of the motor driver based on the difference between the actual current and the target current.

[0089] In this embodiment, the meat grinder uses a permanent magnet DC motor, which can automatically adjust the output torque of the permanent magnet DC motor according to the amount of food, so that the meat grinder can achieve the grinding effect required by the actual application scenario.

[0090] In this embodiment, adjusting the motor's output power based on the difference between the actual current and the target current can effectively enhance the processing efficiency of the meat grinder and avoid the need for the meat grinder to continuously increase the cutting and processing time to improve the cutting effect.

[0091] In one embodiment, the interaction component 120 includes multiple switch buttons corresponding to the granularity of the food ingredient and / or multiple switch buttons corresponding to the type of food ingredient. Each switch button is associated with a corresponding control parameter, which includes a target granularity and a target current. When any switch button is pressed, the interaction component 120 sends an operation command corresponding to the pressed switch button to the controller 110, wherein the operation command includes the control parameter associated with the pressed switch button.

[0092] In this embodiment, the interaction component 120 can be a display screen or a physical switch button. The interaction component 120 includes a preset number of switch buttons, which can be physical buttons or virtual buttons on the display screen. No specific limitation is made here, and the settings can be adaptively configured according to the needs of the actual application scenario.

[0093] In this embodiment, multiple switch buttons correspond to different food particle sizes. Each button is associated with a specific particle size value and current value. For example, there are buttons for 5 mm, 6 mm, 7 mm, and 8 mm particle sizes. It should be noted that the specific particle size values ​​can be defined according to the needs of the actual application.

[0094] Multiple switch buttons correspond to different food types, each associated with a specific particle size and current value. Examples include buttons for meat, leafy vegetables, and root vegetables. Each switch button for a different food type includes a recommended particle size value for processing that food type.

[0095] In one embodiment, when the interactive component 120 is a display screen, the user can also customize the target current and target granularity through the custom processing size function within the display screen.

[0096] In this embodiment, when any switch button is pressed, the interaction component 120 sends an operation command corresponding to the pressed switch button to the controller 110. The operation command includes control parameters associated with the pressed switch button. The controller 110 determines the target control parameters based on the control parameters included in the operation command.

[0097] In one embodiment, the image acquisition component 140 includes a high-speed camera. In this embodiment, the high-speed camera is capable of capturing images at a rate of 1000 frames per second or higher.

[0098] If the actual particle size of the food ingredients in multiple consecutive frames of state images is equal to the target particle size, the controller 110 will control the drive component 130 to stop.

[0099] In this embodiment, the high-speed camera transmits the captured images of the food ingredients back to the controller 110 for processing. The controller 110 identifies the food particles in the images using a preset image recognition algorithm, obtains the actual particle size, and compares it with the target particle size. When the actual particle size of the food ingredients equals the target particle size for the first time, the controller 110 initiates a re-judgment process. When the actual particle size equals the target particle size for N consecutive times (N is an adjustable setting value), the controller 110 controls the motor to stop and determines that the cutting and processing is complete.

[0100] In this embodiment, during the process of repeatedly determining whether the actual particle size equals the target particle size, the actual particle size of the food corresponding to multiple consecutive frames of state images is acquired to perform multiple sets of parameter determination processes. It should be noted that this embodiment, through the recognition and determination of multiple consecutive frames of state images, can ensure that the cutting and processing effect of the meat grinder meets user needs through feedback determination from the image acquisition component 140.

[0101] In one embodiment, a prompting component is also included. In this embodiment, the prompting component may be a buzzer, an alarm, or other device capable of providing an audible alarm. The prompting component is connected to the controller 110, and after the controller 110 controls the drive component 130 to stop, the controller 110 controls the prompting component to sound an alarm.

[0102] In this embodiment, when the controller 110 determines that the meat grinder has completed the cutting process—that is, after the recognition and judgment process of multiple consecutive frames of status images—and the control drive component 130 stops, an audible alarm is triggered by the control prompt component. This promptly reminds the user that the cutting and processing of the food has been completed, allowing the user to easily remove the processed food and achieving intelligent processing.

[0103] In one embodiment, such as Figure 6 As shown, a meat grinder control method is provided, which is applied to... Figure 1 Taking a meat grinder as an example, the explanation includes the following steps:

[0104] S601 generates target control parameters based on the operation instructions of the interactive component, wherein the target control parameters include target granularity and target current.

[0105] S602, the control drive component drives the transmission component to rotate according to the target current, so as to drive the first blade assembly and the second blade assembly to rotate through the transmission component; the first blade assembly is used to cut the food in the internal cavity of the second body, and the second blade assembly is used to stir the food at the bottom of the internal cavity of the second body.

[0106] S603: Obtain a state image of the food in the internal chamber of the second body, and analyze the state image to obtain the actual particle size.

[0107] S604 controls the drive component to stop when the actual granularity equals the target granularity.

[0108] It should be noted that the specific implementation method of the meat grinder control method in this embodiment can be referred to the specific implementation method of the meat grinder in the foregoing equipment embodiment, which will not be repeated here.

[0109] In one embodiment, controlling the drive component to stop when the actual granularity equals the target granularity further includes:

[0110] If the actual granularity of the food ingredients in multiple consecutive frames of state images is equal to the target granularity, the control drive component will stop.

[0111] In summary, this embodiment provides a meat grinder control method. After the user sets the control parameters of the meat grinder through an interactive component, the interactive component sends operation instructions to the controller. The controller obtains the target control parameters according to the operation instructions and controls the drive component to drive the transmission component to rotate according to the target control parameters. The image acquisition component is controlled to acquire the state image of the food inside the internal cavity of the second body. When the transmission component rotates, the first blade component completes the cutting and processing of the food, and the second blade component at least stirs up the food at the bottom of the internal cavity to ensure that the first blade component can fully cut the food, ensuring the cutting and processing effect of the meat grinder. When the actual particle size obtained by the controller through the state image equals the target particle size, the drive component is controlled to stop to complete the cutting and processing of the food. The meat grinder provided in this embodiment can automatically start, automatically cut, ensure cutting effect, and automatically stop according to operation instructions, thus realizing fully automatic processing of meat grinder cutting and processing, greatly improving the ease of use and processing reliability of the meat grinder.
