[0052] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings.

At the same time, the term "and / or" used in this specification includes any and all combinations of the related listed items.

[0058] In related technologies, a household small meat grinder usually controls a driver to drive a blade to rotate by pressing a button at the top, so as to cut and process food materials to obtain food material particles such as meat particles, vegetable particles or garlic particles. Such a household small meat grinder requires the user to continuously press the button and estimate the cutting and processing effect of the food materials through the cutting time, or directly open the bowl cover to check the cutting and processing effect of the food materials. When the cutting and processing effect does not meet the requirements, only by increasing the pressing time of the button, that is, by increasing the cutting time, can the cutting and processing effect be improved. Such a control scheme not only requires the user to spend a lot of time operating the meat grinder, but also cannot ensure that the finally cut and processed food material particles meet the actual requirements.

[0059] In one embodiment, as Figure 1 shown, a meat grinder is provided, including: a first body 100, a second body 200, a controller 110, an interaction component 120, a driving component 130 and an image acquisition component 140 arranged on the first body 100, and a transmission component 210, a first blade assembly 220 and a second blade assembly 230 arranged on the second body 200.

[0060] In this embodiment, the body of the meat grinder is divided into two parts, namely a first body 100 and a second body 200, wherein the first body 100 and the second body 200 are detachably connected. In the actual application process, the controller 110, the driving component 130 and the image acquisition component 140 are arranged inside the first body 100. The interaction component 120 is arranged on the surface of the first body 100. The transmission component 210, the first blade assembly 220 and the second blade assembly 230 which are detachably arranged are arranged inside the second body 200. It should be known that the controller 110, the driving component 130 and the image acquisition component 140 arranged inside the first body 100 and the interaction component 120 arranged on the surface of the second body 200 are all arranged as specified and need to disassemble the first body 100 when moving. The transmission component 210, the first blade assembly 220 and the second blade assembly 230 arranged inside the second body 200 can all be separately disassembled to facilitate cleaning of the transmission component 210, the first blade assembly 220 and the second blade assembly 230.

[0061] In this embodiment, the second body 200 includes an accommodating cavity for placing food materials to be cut and processed. It should be noted that in this embodiment, the specific type of the food materials is not limited, and the food materials to be cut and processed can be meats, vegetables or other food materials suitable for cutting and processing by a small household meat grinder.

[0062] In this embodiment, the controller 110 is respectively connected to the interaction component 120, the driving component 130, and the image acquisition component 140. The controller 110 can be used to perform data transmission and instruction transmission with the interaction component 120, the driving component 130, and the image acquisition component 140 respectively. After the power of the meat grinder is started, the controller 110 generates corresponding control parameters based on the operation instructions 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 driving signals, such as voltage signals, current signals, or PWM signals, to the driving component 130, so that the driving component 130 outputs corresponding power signals to drive the transmission component 210 to rotate. After receiving the operation instructions of 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 state images of the food ingredients in the accommodating cavity of the second body 200 at a certain time period, and receives the state images sent by the image acquisition component 140 to perform corresponding recognition processing.

[0063] In this embodiment, as Figure 2 shown, the driving component 130 is detachably connected to the transmission component 210. The first blade assembly 220 is disposed on the side of the transmission component 210, and the second blade assembly 230 is disposed at the end of the transmission component 210 away from the driving component 130.

[0064] In this embodiment, the transmission component 210 at least includes a rotating shaft and a tool rest, and the tool rest is disposed around the rotating shaft. The rotating shaft of the transmission component 210 is in transmission connection with the driving component 130, and the driving component 130 is used to drive the rotating shaft to rotate and drive the tool rest to rotate.

[0065] In this embodiment, the first blade assembly 220 includes a preset number of cutting blades. As Figure 3As shown, the first blade assembly 220 includes multiple groups 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 no specific limitation is made here. During actual application, the cutting blades of the first blade assembly 220 can be directly sleeved on the rotating shaft of the transmission assembly 210, that is, a hole corresponding to the shaft shape of the rotating shaft is opened at the connecting part (middle area or end area) of the blade, and then the rotating shaft passes through the blade through the opening, and is arranged on both sides of the blade by using a tool rest or other fixing parts to fix the setting position of the blade. The first blade assembly 220 can also be directly embedded in the tool rest of the transmission assembly 210, and the connecting part of the blade is directly inserted into the embedding hole reserved in the tool rest. The first blade assembly 220 can also be an integral structure with the tool rest. It should be noted that the first blade assembly 220 can be arranged on the transmission assembly 210 by any assembly and setting method in the related art. The first blade assembly 220 is arranged 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 inner cavity of the second body 200.

[0066] 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 inner cavity of the second body 200 is less than a preset distance, so as to stir the food debris at the bottom of the inner 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 inner cavity of the second body 200 is less than a preset distance, so as to scrape off the food debris on the side surface of the inner 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 when the second blade structure is made of rubber or elastic plastic, the bottom surface and the vertical surface of the L-shaped blade structure can directly contact the inner wall of the inner cavity of the second body 200, avoiding scratching and damaging the second body 200. In the actual application scenario, 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 no specific limitation is made here.

[0067] In actual application, the first body 100 and the second body 200 are detachably connected. When the first body 100 and the second body 200 are in the connected state, the drive assembly 130 and the transmission assembly 210 are in the connected state. When the first body 100 and the second body 200 are in the separated state, the drive assembly 130 and the transmission assembly 210 are in the separated state. In this embodiment, when the first body 100 and the second body 200 are in the connected state, the body of the first body 100 and the body of the second body 200 form a closed space, thereby preventing the food from splashing out of the inner cavity of the second body 200 during the cutting and processing of the food.

[0068] In this embodiment, the processing process of the meat grinder for cutting food ingredients can be carried out according to the following device interaction logic:

[0069] First, the user operates the interaction component 120 to cause the interaction component 120 to generate a corresponding operation instruction and send the operation instruction to the controller 110. The controller 110 generates target control parameters according to the operation instruction of the interaction component 120, where the target control parameters include a target particle size and a target current.

[0070] Then, the controller 110 controls the drive component 130 to drive the transmission component 210 to rotate according to the target current. The transmission component 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 ingredients in the inner cavity of the second body 200. When the second blade assembly 230 rotates, it is at least used to stir the food ingredients at the bottom of the inner cavity of the second body 200.

[0071] While the controller 110 controls the drive component 130 to drive the transmission component 210 to rotate according to the target current, the image acquisition component 140 is used to capture a state image of the food ingredients in the inner cavity of the second body 200 and send the state image to the controller 110.

[0072] Finally, the controller 110 obtains the actual particle size according to the state image and compares the target particle size with the actual particle size. When the actual particle size is equal to the target particle size, the drive component 130 is controlled to stop.

[0073] In this embodiment, a corresponding image analysis and recognition algorithm is built in the controller 110, which is used to analyze and recognize food ingredient-related parameters such as the type of food ingredients placed in the inner cavity of the second body 200 and the food ingredient particle size according to the state image. It should be noted that the image analysis and recognition algorithm can use the algorithms in related technologies and will not be elaborated here.

[0074] In summary, this embodiment provides a meat grinder. After the user operates and sets the control parameters of the meat grinder through the interaction component 120, the interaction component 120 sends an operation instruction to the controller 110. The controller 110 obtains the target control parameters according to the operation instruction, and respectively controls the driving component 130 to drive the transmission component 210 to rotate, and controls the image acquisition component 140 to acquire the state image of the food ingredients in the inner cavity of the second body 200. When the transmission component 210 rotates, the first blade assembly 220 completes the cutting process of the food ingredients, and the second blade assembly 230 at least stirs up the food ingredients at the bottom of the inner cavity to ensure that the first blade assembly 220 can fully cut the food ingredients and guarantee the cutting 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 driving component 130 is controlled to stop, so as to complete the cutting process of the food ingredients. The meat grinder provided by this embodiment can complete automatic startup, automatic cutting, cutting effect guarantee and automatic shutdown according to the operation instruction, that is, it realizes the full-automatic processing of the cutting of the meat grinder, greatly improves the convenience of use of the meat grinder, and improves the processing reliability of the meat grinder.

[0075] In one embodiment, as Figure 3 and Figure 5 shown, the second blade assembly 230 includes a bottom blade and a side blade. Among them, the connecting part of the bottom blade is provided with corresponding openings so that the second blade assembly 230 can be sleeved on the end of the transmission component 210. When the transmission component 210 rotates, it drives the bottom blade and the side blade to rotate.

[0076] The second blade assembly 230 is used to stir up the food ingredients at the bottom of the inner cavity of the second body 200 through the bottom blade and scrape off the food ingredients on the side of the inner cavity of the second body 200 through the side blade.

[0077] In this embodiment, the bottom blade and the side blade can be an integral structure. Or 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 simultaneously rotate in the same direction and at the same speed according to the acting force provided by the transmission component 210.

[0078] In this embodiment, the bottom blade stirs the food materials at the bottom of the inner chamber of the second body 200 during rotation to prevent food material debris from sticking to the bottom of the inner chamber of the second body 200. The side blade scrapes off the food materials on the side of the inner chamber of the second body 200 during rotation to prevent food material debris from sticking to the side of the inner chamber of the second body 200. By providing the bottom blade and the side blade, it can effectively ensure that food material debris does not stick to the inner wall of the second body 200, and the meat grinder can fully cut and process food materials.

[0079] It should be noted that the second blade assembly 230 at least stirs the food materials at the bottom of the inner chamber of the second body 200 because no matter how the first blade assembly 220 cuts and processes the food materials, the food materials will first fall to the bottom of the inner chamber of the second body 200. Therefore, the second blade assembly 230 in this embodiment at least needs to ensure that the food materials at the bottom of the inner chamber are stirred to the cutting and processing area of the first blade assembly 220.

[0080] In one embodiment, as Figure 4 shown, the bottom blade includes a plurality of convex structures.

[0081] In this embodiment, by providing a preset number of convex structures on the bottom blade, the bottom blade as a whole has a serrated shape, which can ensure sufficient stirring of the food material debris at the bottom of the inner chamber and improve the cutting and processing effect of the meat grinder.

[0082] In one embodiment, the shape of the convex structure can be a triangular protrusion, a trapezoidal protrusion, an oval protrusion or an irregular protrusion, and the shape of the convex structure can be configured according to the needs of the actual application scenario.

[0083] In one embodiment, the side blade includes a plurality of convex structures.

[0084] In this embodiment, by providing convex structures on the side blade, it can effectively improve the scraping of the food material debris sticking to the side of the inner chamber of the second body 200 by the side blade.

[0085] Optionally, the distance between the convex structures provided on the side blade and the bottom of the inner chamber of the second body 200 is less than a preset distance threshold. In this embodiment, by providing convex structures in the area where the side blade is close to the bottom of the inner chamber, it can cooperate with the convex structures on the bottom blade to further improve the stirring effect on the food material debris at the bottom of the inner chamber, so as to improve the cutting and processing effect of the meat grinder.

[0086] In one embodiment, the constituent material of the second blade assembly 230 includes an elastic material, where the elastic material includes rubber or soft plastic. In this embodiment, by making the second blade assembly 230 from the elastic material, the second blade assembly 230 can directly contact the inner wall of the inner chamber of the second fuselage 200 to maximize the stirring and scraping effects of the second blade assembly 230.

[0087] In one embodiment, as Figure 5 shown, the meat grinder further includes a reduction gear set disposed on the second fuselage 200, and the reduction gear set is disposed at the end of the transmission assembly 210 away from the drive assembly 130. The second blade assembly 230 is in transmission connection with the transmission assembly 210 through 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, where the rotational speed of the second blade assembly 230 is less than the rotational speed of the first blade assembly 220.

[0088] In this embodiment, the reduction gear set is composed of multiple gears, and these gears transmit power through meshing with each other. 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 through gears of different sizes. In actual application scenarios, a small gear (driving gear) can drive a large gear (driven gear) to achieve the deceleration effect.

[0089] The reduction ratio of the reduction gear set refers to the ratio of the rotational speed of the input gear to the rotational speed of the output gear, and it can also be calculated through the number of teeth of the gears, that is, reduction ratio = number of teeth of the input gear / number of teeth of the output gear.

[0090] In this embodiment, the second blade assembly 230 is in transmission connection with the transmission assembly 210 through the reduction gear set, which can ensure that the rotational speed of the second blade assembly 230 is lower than that of the first blade assembly 220 throughout the processing of the meat grinder, and ensure that the rotational speed of the second blade assembly 230 is always in a low-speed rotation state to ensure the scraping and stirring effects of the second blade assembly 230.

[0091] In this embodiment, the rotational speed output by the motor directly acts on the rotating shaft of the transmission assembly 210 to drive the first blade assembly 220 to cut and process the food ingredients. At the same time, through the speed reduction of the reduction gear set, the rotational speed is output to the second blade assembly 230 with the same rotating shaft. As Figure 5 shown, the second blade assembly 230 rotates against the inner wall of the second fuselage 200, and can scrape off the food ingredients inside the second fuselage 200.

[0092] In one embodiment, the meat grinder further includes a current detection component disposed on the first body 100. The current detection component is respectively connected to the drive component 130 and the controller 110. The current detection component is used to detect the actual current of the drive component 130 and send the actual current to the controller 110. The controller 110 adjusts the output power of the drive component 130 according to the difference between the actual current and the target current so that the actual current is equal to the target current.

[0093] In this embodiment, the current detection component can use a current sensor, a current detection circuit, or other devices, chips, or integrated circuits capable of detecting real-time current.

[0094] This embodiment is based on the PID control algorithm. By comparing the actual current and the target current, the difference between the actual current and the target current is calculated, and the drive voltage of the drive component 130 is adjusted according to the difference. The controller 110 sends a drive control signal corresponding to the drive voltage to the motor driver, and timely adjusts the output power of the motor driver to keep the actual current always equal to the target current. Based on the above steps, when the meat grinder stirs the ingredients, it will adaptively adjust the output power of the motor driver according to the amount and size of the ingredients to ensure the cutting and processing effect of the ingredients.

[0095] In one embodiment, the drive component 130 includes a motor driver and a permanent magnet DC motor. The motor driver is respectively connected to the controller 110 and the permanent magnet DC motor, and the permanent magnet DC motor is detachably connected to the transmission component 210. The current detection component is connected to the permanent magnet DC motor for detecting the actual current of the permanent magnet DC motor. The controller 110 adjusts the output power of the motor driver according to the difference between the actual current and the target current.

[0096] In this embodiment, the motor used in the meat grinder is a permanent magnet DC motor, and thus the output torque of the permanent magnet DC motor can be automatically adjusted according to the amount of ingredients, so that the meat grinder achieves the grinding effect required by the actual application scenario.

[0097] In this embodiment, by adjusting the output power of the motor based on the difference between the actual current and the target current, the processing efficiency of the meat grinder can be effectively enhanced, and it is avoided that the meat grinder needs to continuously increase the time to improve the cutting and processing effect.

[0098] In one embodiment, the interaction component 120 includes a plurality of switch buttons corresponding to the ingredient particle size and / or a plurality of switch buttons corresponding to the ingredient type. Each switch button is associated with a corresponding control parameter, and the control parameter includes a target particle size and a target current. When any switch button is pressed, the interaction component 120 sends an operation instruction corresponding to the pressed switch button to the controller 110, and the operation instruction includes the control parameter associated with the pressed switch button.

[0099] 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, and the switch button can be a physical button or a virtual button on the display screen. There is no specific limitation here, and it can be adaptively set according to the needs of the actual application scenario.

[0100] In this embodiment, for multiple switch buttons corresponding to the food material granularity, each button is associated with a corresponding granularity value and current value. For example, a button for a granularity size of 5 millimeters (mm), buttons for granularity sizes of 6 mm, 7 mm, and 8 mm, etc. It should be noted that the specific values of the food material granularity can be defined according to the needs of the actual application.

[0101] For multiple switch buttons corresponding to the food material types, each button is also associated with a corresponding granularity value and current value. For example, a meat button, a leafy vegetable button, and a root vegetable button, etc. Among them, the switch buttons for different food material types all include the recommended values of the granularity sizes of the processing effects corresponding to the food material types.

[0102] In one embodiment, when the interaction component 120 is a display screen, the user can also customize the target current and target granularity through the custom processing size function in the display screen.

[0103] In this embodiment, when any switch button is pressed, the interaction component 120 sends an operation instruction corresponding to the pressed switch button to the controller 110. Among them, the operation instruction includes the control parameters associated with the pressed switch button. The controller 110 determines the target control parameters according to the control parameters included in the operation instruction.

[0104] In one of the embodiments, the image acquisition component 140 includes a high-speed camera. In this embodiment, the high-speed camera can perform shooting at a standard of 1000 frames per second or more.

[0105] When the actual granularity of the food material in the consecutive multi-frame status images is equal to the target granularity, the controller 110 controls the driving component 130 to stop.

[0106] In this embodiment, the high-speed camera transmits the captured status image of the food material back to the controller 110 for processing. The controller 110 identifies the food material particles in the status image through a preset image recognition algorithm to obtain the actual granularity, and compares it with the target granularity. When the actual granularity of the food material particles is equal to the target granularity for the first time, the controller 110 starts a rejudgment process. When it is determined that the actual granularity is equal to the target granularity for N consecutive times (N is an adjustable set value), the controller 110 controls the motor to stop and determines that the cutting and processing are completed.

[0107] In this embodiment, during the process of continuously determining whether the actual particle size is equal to the target particle size for multiple times, the actual particle size of the food material corresponding to multiple consecutive frames of status images is obtained to perform multiple groups of parameter determination processes. It should be noted that in this embodiment, through the recognition and determination of multiple consecutive frames of status images, and through the feedback determination of the image acquisition component 140, it can be ensured that the cutting and processing effect of the meat grinder meets the user's requirements.

[0108] In one embodiment, it further includes a prompting component. In this embodiment, the prompting component can be a buzzer, an alarm or other devices capable of making a sound alarm. The prompting component is connected to the controller 110, and after the controller 110 controls the driving component 130 to stop, the controller 110 controls the prompting component to give an alarm.

[0109] In this embodiment, when the controller 110 determines that the meat grinder has completed the cutting and processing, that is, after the recognition and determination process of multiple consecutive frames of status images, when controlling the driving component 130 to stop, by controlling the prompting component to give a sound alarm, the user can be timely reminded that the cutting and processing of the food material has been completed. It is convenient for the user to timely take out the processed food material, realizing intelligent processing.

[0110] In one embodiment, as Figure 6 shown, a meat grinder control method is provided. Taking the meat grinder in Figure 1 as an example for illustration, it includes the following steps:

[0111] S601, generate target control parameters according to the operation instruction of the interaction component, where the target control parameters include a target particle size and a target current.

[0112] S602, control the driving component to drive the transmission component to rotate according to the target current, so as to drive the first blade component and the second blade component to rotate through the transmission component; the first blade component is used to cut the food material in the inner cavity of the second body, and the second blade component is at least used to stir the food material at the bottom of the inner cavity of the second body.

[0113] S603, obtain the status image of the food material in the inner cavity of the second body, and analyze the actual particle size according to the status image.

[0114] S604, when the actual particle size is equal to the target particle size, control the driving component to stop.

[0115] It should be noted that the specific implementation manner of the meat grinder control method in this embodiment can refer to the specific implementation manner of the meat grinder in the foregoing device embodiment, and will not be elaborated here one by one.

[0116] In one embodiment, when the actual particle size is equal to the target particle size and the driving component is controlled to stop, it further includes:

[0117] When the actual granularity of the food ingredients corresponding to consecutive multi-frame state images is equal to the target granularity, control the driving component to stop.

[0118] In summary, this embodiment provides a meat grinder control method. After the user operates through the interaction component to set the control parameters of the meat grinder, the interaction component sends an operation instruction to the controller. The controller obtains the target control parameters according to the operation instruction, and respectively controls the driving component to drive the transmission component to rotate according to the target control parameters, and controls the image acquisition component to acquire the state image of the food ingredients in the internal cavity of the second body. When the transmission component rotates, the first blade component completes the cutting process of the food ingredients, and the second blade component at least stirs up the food ingredients at the bottom of the internal cavity to ensure that the first blade component can fully cut the food ingredients and guarantee the cutting effect of the meat grinder. When the actual granularity obtained by the controller through the state image is equal to the target granularity, control the driving component to stop to complete the cutting process of the food ingredients. The meat grinder provided in this embodiment can complete automatic startup, automatic cutting, cutting effect guarantee, and automatic shutdown according to the operation instruction, that is, it realizes the full-automatic processing of the cutting of the meat grinder, greatly improves the convenience of use of the meat grinder, and improves the processing reliability of the meat grinder.
