[0039] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0040] In related technologies, small household meat grinders typically cut ingredients directly with rotating blades to produce particles such as meat, vegetables, or garlic. During the cutting process, food often splatters onto the inner walls and bottom of the container, and this residue is often incompletely processed, leading to waste. Furthermore, directly cutting with rotating blades cannot guarantee that the food is cut to a uniform size throughout the container, resulting in poor grinding performance and a negative user experience.

[0041] like Figure 1 As shown, the meat grinder provided in this application embodiment includes: a first body 100, a second body 200, a controller 110, a switch 120 and a drive assembly 130 disposed on the first body 100, a transmission assembly 210 disposed on the second body 200, a first blade assembly 220, a spiral blade 230 and a second blade assembly 240.

[0042] 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 and a drive assembly 130. A switch 120 is mounted on the surface of the first body 100. The second body 200 houses a detachable transmission assembly 210, a first blade assembly 220, a spiral blade 230, and a second blade assembly 240. It should be noted that the controller 110 and drive assembly 130 inside the first body 100, as well as the switch 120 on the surface of the first body 100, are all fixedly installed; disassembly of the first body 100 is required for movement. The transmission assembly 210, the first blade assembly 220, the spiral blade 230, and the second blade assembly 240 installed inside the second body 200 can all be disassembled individually to facilitate cleaning of the transmission assembly 210, the first blade assembly 220, the spiral blade 230, and the second blade assembly 240.

[0043] 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.

[0044] In this embodiment, the controller 110 is connected to the switch 120 and the drive assembly 130. The controller 110 is used to transmit data and commands to the switch 120 and the drive assembly 130, respectively. After the meat grinder is powered on, when the user operates the switch 120, the controller 110 controls the meat grinder to perform cutting processing according to a preset drive signal based on the pressed state of the switch 120. The controller 110 sends a corresponding drive signal, such as a voltage signal, a current signal, or a PWM signal, to the drive assembly 130 so that the drive assembly 130 outputs a corresponding power signal, driving the transmission assembly 210 to rotate.

[0045] 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 located on the transmission assembly 210 at a preset distance from the bottom of the second body 200. The second blade assembly 240 is located at the end of the transmission assembly 210 away from the drive assembly 130. The spiral blade 230 surrounds the area on the transmission assembly 210 between the first blade assembly 220 and the second blade assembly 240.

[0046] In this embodiment, the transmission assembly 210 includes at least a rotating shaft and a fixed structure, with the fixed structure 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 fixed structure.

[0047] In this embodiment, the first blade assembly 220 includes a reamer blade, which is disposed on the rotating shaft of the transmission assembly 210 and directly connected to the rotating shaft, rotating with the shaft. In practical applications, the reamer blade can be crescent-shaped. It should be noted that the number and specific shape of the reamer blades can be configured according to the needs of the actual application scenario, and are not specifically limited here. In this embodiment, the reamer blade can be directly fitted onto the rotating shaft of the transmission assembly 210, that is, a hole corresponding to the shape of the rotating shaft is opened in the connecting part (middle area or end area) of the blade, and the rotating shaft passes through the hole and is fixed on both sides of the blade using a fixing structure to fix the blade's position. In this embodiment, the first blade assembly 220 is disposed at a preset distance from the bottom of the second body 200. This preset distance can be determined according to the actual dimensions of the rotating blade and the second blade assembly 240, and the first blade assembly 220 is disposed above the rotating blade and the second blade assembly 240. In practical applications, the first blade assembly 220 and the drive assembly 130 are spaced a certain distance apart to form a certain accommodating space for temporarily storing food particles after the first blade assembly 220 has cut the food.

[0048] The second blade assembly 240 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.

[0049] In this embodiment, the spiral blade 230 is disposed between the first blade assembly 220 and the second blade assembly 240. The spiral blade 230 is mounted on a fixed structure in front of the first blade assembly 220 and the second blade assembly 240. This fixed structure can be a blade holder or other embeddable structure. The spiral blade 230 and the rotating shaft are at a certain angle. When the spiral blade 230 rotates, it can be used to gradually convey the food from the bottom of the internal cavity of the second body 200 to the cutting and processing area of ​​the first blade above.

[0050] In this embodiment, the meat grinder processes the food ingredients as follows:

[0051] When the user operates the switch 120 to close, the controller 110 controls the drive assembly 130 to drive the transmission assembly 210 to rotate according to a preset drive signal. The transmission assembly 210 drives the first blade assembly 220, the spiral blade 230, and the second blade assembly 240 to rotate, thereby processing the food. Specifically, the first blade assembly 220 is used to cut the food, the spiral blade 230 is used to push the food towards the processing area of ​​the first blade assembly 220, and the second blade assembly 240 is used to at least tumble the food at the bottom of the internal chamber of the second body 200.

[0052] In this embodiment, the preset drive signal includes at least a drive current. The drive component 130 drives the transmission component 210 to rotate according to the preset drive current, ensuring that the meat grinder can operate under a stable load, thereby ensuring that the first blade assembly 220 can effectively cut the food. In one embodiment, the preset drive signal in this embodiment can be configured in advance so that the meat grinder can be specifically used to process a specific type of food. For example, by configuring the preset drive signal to correspond to meat, the drive component can drive the transmission component to rotate according to the corresponding power, so that the meat grinder is specifically used to cut and process meat. Alternatively, by configuring the preset drive signal to correspond to vegetable food, the drive component can drive the transmission component to rotate according to the corresponding power, so that the meat grinder is specifically used to cut and process vegetable food.

[0053] In this embodiment, the second blade assembly 240 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 240 needs to at least ensure that the food at the bottom of the internal cavity is tumbled in the transport area of ​​the spiral blade 230, and then the spiral blade 230 transports the food to the cutting and processing area of ​​the first blade assembly 220.

[0054] In summary, this embodiment provides a meat grinder. By configuring a first blade assembly 220, a spiral blade 230, and a second blade assembly 240 within the second body 200, it can ensure that the ingredients placed within the second body 200 are fully cut and processed. The second blade assembly 240 continuously stirs the ingredients at the bottom of the container to prevent them from sticking or becoming stagnant. The spiral blade 230 continuously transports the ingredients to the cutting and processing area of ​​the first blade assembly 220, thereby ensuring that all ingredients placed within the second body 200 are effectively cut and processed.

[0055] In one embodiment, such as Figure 3 As shown, the second blade assembly 240 includes a bottom blade and a side blade. The bottom blade has a corresponding opening at its connecting portion, allowing the second blade assembly 240 to be fitted into the end of the transmission assembly 210. When the transmission assembly 210 rotates, it simultaneously drives the bottom blade and the side blade to rotate.

[0056] When the bottom blade and the side blade rotate, the bottom blade is used to stir the food at the bottom of the internal chamber of the second body 200, and the side blade is used to scrape off the food on the side of the internal chamber of the second body 200.

[0057] 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 240 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.

[0058] 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.

[0059] In one embodiment, such as Figure 3 As shown, the bottom blade includes multiple protruding structures.

[0060] 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.

[0061] 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.

[0062] In one embodiment, the side blade includes multiple protrusions.

[0063] 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.

[0064] 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.

[0065] In one embodiment, the second blade assembly 240 is composed of an elastic material, wherein the elastic material includes rubber or soft plastic.

[0066] In this embodiment, the second blade assembly 240 is made of an elastic material, which allows the second blade assembly 240 to directly contact the inner wall of the internal cavity of the second body 200, thereby maximizing the stirring and scraping effects of the second blade assembly 240.

[0067] In one embodiment, such as Figure 2 As shown, it also includes a reduction gear set 250 disposed on the second body 200. The reduction gear set 250 is disposed on the transmission assembly 210 between the first blade assembly 220 and the helical blade 230.

[0068] The reduction gear set 250 is used to reduce the rotational speed of the helical blade 230 and the second blade assembly 240 according to a preset reduction ratio, wherein the rotational speed of the helical blade 230 and the rotational speed of the second blade assembly 240 are both less than the rotational speed of the first blade assembly 220.

[0069] In this embodiment, the reduction gear set 250 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 250 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.

[0070] The reduction ratio of the 250 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.

[0071] In this embodiment, the reduction gear set 250 is positioned below the first blade assembly 220 and above the spiral blade 230 to ensure that the rotational speed of the spiral blade 230 and the rotational speed of the second blade assembly 240 are both lower than the rotational speed of the first blade assembly 220 throughout the meat grinder processing, thereby improving the conveying force of the spiral blade 230 and the scraping effect of the second blade assembly 240.

[0072] In one embodiment, the number of reduction gear sets 250 can be multiple sets. For example, two different reduction gear sets 250 can be respectively arranged between the first blade assembly 220 and the helical blade 230 on the transmission assembly 210, and between the helical blade 230 and the second blade assembly 240 on the transmission assembly 210.

[0073] The reduction gear set 250 is used to reduce the rotational speed of the helical blade 230 and the second blade assembly 240 according to a preset reduction ratio, wherein the rotational speed of the helical blade 230 is less than the rotational speed of the first blade assembly 220, and the rotational speed of the second blade assembly 240 is less than the rotational speed of the helical blade 230.

[0074] In this embodiment, by respectively arranging two sets of reduction gears on the rotating shaft of the transmission assembly 210, the rotational speeds of the helical blade 230 and the second blade assembly 240 are reduced, thereby enabling the first blade assembly 220, the helical blade 230, and the second blade assembly 240 to rotate at different speeds. It should be noted that the preset reduction ratios of the reduction gear set between the first blade assembly 220 and the helical blade 230 and the reduction gear set between the helical blade 230 and the second blade assembly 240 can be the same or different. Appropriate reduction gear sets can be selected to reduce the rotational speeds of the helical blade 230 and the second blade assembly 240 according to the needs of the actual application scenario.

[0075] In this embodiment, by setting the rotation speeds of the first blade assembly 220, the spiral blade 230, and the second blade assembly 240 in stages, the food cutting and processing effect of the first blade assembly 220 can be guaranteed while improving the food transport efficiency of the spiral blade 230. This allows the spiral blade 230 to push the food from the bottom of the internal chamber to the food cutting and processing area more quickly, and ensures that the second blade assembly 240 can stably tumble the food at the bottom of the internal chamber and catch the food on the side wall of the internal chamber.

[0076] In one embodiment, a current detection component is also provided on the first body 100; the current detection component is connected to the drive component 130 and the controller 110 respectively; 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.

[0077] 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.

[0078] 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 130130 is adjusted according to this difference. The controller 110110 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.

[0079] In one embodiment, the drive assembly 130 includes a motor driver and a motor; the motor driver is connected to the controller 110 and the motor respectively, and the motor is detachably connected to the transmission assembly 210; the current detection assembly is connected to the motor and is used to detect the actual current of the motor; the controller 110 adjusts the output power of the motor driver according to the difference between the actual current and the target current.

[0080] In this embodiment, the motor used in the meat grinder can be 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.

[0081] 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.

[0082] In one embodiment, the controller 110 determines that food processing is complete when the real-time load of the drive component 130 is maintained at a fixed value for a time greater than or equal to a preset time threshold.

[0083] In this embodiment, since the drive control parameters of the drive component 130 are preset drive signals, the drive current of the drive component 130, i.e., the real-time load of the drive component 130, will eventually be fixed at a constant value, which corresponds to the preset drive signal. When the real-time load of the drive component 130 is maintained at the constant value for a time greater than or equal to a preset time threshold, the controller 110 can determine that the food processing is complete.

[0084] In one embodiment, when the switch 120 is an automatic pop-up switch, the controller 110 can control the closed switch 120 to pop up when the real-time load of the drive component 130 is maintained at a set value for a time greater than or equal to a preset time threshold, so that the controller 110 controls the drive component 130 to stop.

[0085] In one embodiment, when the switch 120 is a switch button that requires continuous pressing by the user, the meat grinder also includes a prompting component. The prompting component is connected to the controller 110. The prompting component may be a buzzer, alarm, or other device capable of providing an audible alarm.

[0086] If the controller 110 maintains the real-time load of the drive component 130 at a set value for a time greater than or equal to a preset time threshold, the control prompt component will issue an alarm.

[0087] In this embodiment, the controller 110 controls the alarm of the prompting component, which can remind the user to release the switch button so that the drive component 130 can stop. This can control the meat grinder to stop processing in time, ensuring the processing effect while avoiding prolonged use that could affect the product's lifespan.

[0088] In summary, this embodiment provides a meat grinder that can achieve adaptive grinding control through current PID control. Combined with the first blade assembly 220, the second blade assembly 240, and the spiral blade 230, it maximizes the processing performance of the meat grinder, ensuring that the ingredients placed inside are thoroughly cut and processed. Preferably, when processing meat, this meat grinder can effectively prevent meat from piling up and achieve comprehensive cutting and processing of the meat, resulting in a finer grinding effect.
