Description

Technical Field

[0001] This application belongs to the field of meat grinder technology, and particularly relates to a meat grinder. Background Technology

[0002] A food processor, such as a meat grinder, includes a main unit, a grinding bowl, a lid covering the grinding bowl, and a blade assembly placed inside the grinding bowl. The main unit, located on the lid, includes a motor. The motor drives the blade assembly to rotate inside the grinding bowl, thereby grinding the meat into minced meat.

[0003] However, traditional household meat grinders have a limited capacity for grinding meat. If the amount of meat to be ground is increased slightly, it usually needs to be ground in several batches. In some special cases, such as when using frozen meat directly for grinding, it is even more necessary to reduce the amount of meat to be ground in a single batch. However, the motor of a general meat grinder does not have heat dissipation capabilities, and prolonged operation can lead to motor damage. Summary of the Invention

[0004] The purpose of this application is to address the aforementioned technical problems by providing a meat grinder that improves the heat dissipation of the main unit and enables stable operation over extended periods.

[0005] This application provides a meat grinder, including a meat grinding bowl, a bowl lid, a meat grinding blade, and a main unit, wherein the main unit includes: The housing includes a bottom cover and a top cover, which are located at both ends of the housing; Dual-head motor, installed inside the housing; The fan is installed inside the housing and on one of the output shafts of the dual-head motor; The clutch assembly is located between the dual-head motor and the fan; The housing is provided with a movable cover, which includes two openings. The housing is provided with an air inlet and an air outlet corresponding to the two openings, respectively. The air inlet and air outlet are provided with protective nets. The housing is provided with an air inlet channel connected to the air inlet, which leads to the end of the dual-head motor near the bottom cover.

[0006] The meat grinder bowl is used to hold meat chunks. The meat grinder blade engages with the positioning structure at the bottom of the bowl. The bowl lid is then placed on top of the bowl, and the main unit is placed on the lid, connecting to the meat grinder blade. The main unit drives the meat grinder blade to grind the meat. The main unit uses a dual-head motor installed inside as its power source. The bottom cover, top cover, and housing are fixed together with screws and other connectors. After the main unit and bowl lid are engaged, the bottom cover and bowl lid abut against each other. The fan is installed inside the housing, and a clutch assembly is located between the dual-head motor and the fan. The clutch assembly controls the fan's operation when cooling is needed. If the dual-head motor overheats due to repeated grinding or grinding of frozen meat, and if the number of consecutive grinding cycles does not exceed two, and each grinding session involves non-frozen, soft meat, the clutch assembly can be used to control the fan's operation. The fan is kept stationary to reduce energy consumption. When the clutch assembly engages with the fan, it drives the fan to rotate, allowing air to enter through the air inlet and be guided through the air intake channel to the end of the dual-head motor near the bottom cover. The air then flows through the outer wall of the dual-head motor and is discharged through the air outlet. The airflow within the housing accelerates the heat dissipation of the dual-head motor. The movable cover, air inlet, and air outlet are located on the housing near the top cover. The movable cover is movably fitted onto the housing. When the two openings correspond to the air inlet and air outlet respectively, airflow within the housing is achieved. When heat dissipation is not required, the openings are staggered from the air inlet and air outlet to reduce dust entering the housing. The protective mesh enhances the protection of the housing at the air inlet and air outlet, preventing fingers, objects, etc., from entering the housing, protecting the fan, and improving safety performance.

[0007] Furthermore, the host also includes: Mounting base, installed inside the housing and used to mount a dual-head motor, the mounting base is provided with guide holes, the guide holes being evenly distributed around the axis of the dual-head motor; Heat sink, connected between the dual-head motor and the mounting base; A bracket is placed between the fan and the housing, and the bracket is movably connected to the fan.

[0009] Furthermore, the host also includes: A spiral tube is wound around the outside of the heat sink; Pump body, mounted on a bracket; The guide plate is hollow, and the guide plate, spiral tube, and pump body are connected. The pump body and the fan are connected and driven by two gears.

[0010] Furthermore, the host also includes: The output base is movably mounted on the bottom cover and connected to the output shaft of the dual-head motor. The output base is provided with a mating hole corresponding to the meat grinder. The connector is movable and can be easily mounted on the output socket. A control valve assembly, mounted on a movable joint, is used to control the flow of coolant. The first valve body has two parts and is installed on the output seat; The meat grinder has a connector at its end, which is connected to a second valve body corresponding to the first valve body. The meat grinder has a water passage connecting the two second valve bodies. The connector has a seal corresponding to the mating hole. The movable joint has two inner ring grooves, and the output seat has two outer ring grooves. The inner and outer ring grooves are respectively sealed and fitted. The inner ring grooves are connected to the guide plate and the spiral tube, respectively, and the outer ring grooves are connected to the first valve body.

[0011] Furthermore, the first valve body and the second valve body include: The valve stem is equipped with a piston; The second spring abuts against the valve stem; The abutting portion is aligned with the axis of the valve stem, and the abutting portion extends outward along the axis from the valve stem and has a radially outward taper; The abutting portions of the first valve body and the second valve body correspond to each other.

[0012] Furthermore, the control valve assembly includes: The movable core is movably installed on the movable connector; Electromagnets are respectively placed between the two ends of the movable core and the movable joint; The movable core is provided with a groove and a connecting hole.

[0013] Furthermore, the host also includes: The handle is located on the top cover; A control switch, mounted on the handle, is used to control the movement of the control valve assembly.

[0021] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0022] Example 1:

[0023] like Figure 1 , Figure 2 As shown, this application embodiment provides a meat grinder, including a meat grinding bowl 001, a bowl lid 002, a meat grinding blade 200, and a main unit 100, wherein the main unit 100 includes: The housing 110 includes a bottom cover 112 and a top cover 111, wherein the bottom cover 112 and the top cover 111 are located at both ends of the housing 110; A dual-head motor 120 is installed inside the housing 110; Fan 130 is installed inside housing 110 and on one of the output shafts of dual-head motor 120; The clutch assembly 300 is positioned between the dual-head motor 120 and the fan 130; The housing 110 is provided with a movable cover 140, which includes two openings 141. The housing 110 is provided with an air inlet 113 and an air outlet 114 corresponding to the two openings 141 respectively. The air inlet 113 and the air outlet 114 are provided with protective nets 150. The housing 110 is provided with an air inlet channel 115 connected to the air inlet 113. The air inlet channel 115 leads to the end of the dual-head motor 120 near the bottom cover 112.

[0024] The meat grinding bowl 001 is used to hold meat chunks. The meat grinding blade 200 engages with the positioning structure at the bottom of the meat grinding bowl 001. Then, the bowl lid 002 is placed on the meat grinding bowl 001, and the main unit 100 is placed on the bowl lid 002, connecting the main unit 100 with the meat grinding blade 200. The main unit 100 drives the meat grinding blade 200 to rotate and grind the meat. The main unit 100 uses a dual-head motor 120 installed inside as its driving power source. The bottom cover 112, top cover 111, and housing 110 are fixedly connected by screws and other connectors. After the bottom cover 112 and the bowl cover 002 are engaged, the bottom cover 112 abuts against the bowl cover 002. The fan 130 is installed inside the housing 110. The clutch assembly 300 is located between the dual-head motor 120 and the fan 130. The clutch assembly 300 can control the fan 130 to work when heat dissipation is needed. For example, if meat needs to be ground repeatedly or frozen meat needs to be minced, causing the dual-head motor 120 to overheat, if the number of consecutive meat grinding times does not exceed 2, and each time the meat is ground in a non-frozen soft state, the fan 130 can be controlled by the clutch assembly 300. The 300 motor operates without rotation, reducing energy consumption. When the clutch assembly 300 engages with the fan 130, it drives the fan 130 to rotate, causing air to enter through the air inlet 113, be guided through the air intake channel 115 to the end of the dual-head motor 120 near the bottom cover 112, and then flow through the outer wall of the dual-head motor 120 and be discharged from the air outlet 114. The airflow within the housing 110 accelerates the heat dissipation of the dual-head motor 120. The movable cover 140, air inlet 113, and air outlet 114 are distributed on the housing 110 near the top cover 111. The movable cover 140 is movably fitted onto the housing 110. When the two openings 141 correspond to the air inlet 113 and the air outlet 114 respectively, air circulation can be achieved inside the housing 110. When the heat dissipation function is not required, the openings 141 are staggered from the air inlet 113 and the air outlet 114 to reduce dust from entering the housing 110. The protective net 150 improves the protection of the housing 110 at the air inlet 113 and the air outlet 114, preventing fingers, objects, etc. from entering the housing 110, protecting the fan 130, and improving safety performance.

[0025] Example 2:

[0026] like Figure 2 As shown, this application embodiment provides a meat grinder, which, in addition to including the above-mentioned technical features, further includes the following in the main unit 100: Mounting base 160 is installed inside housing 110 and used to mount dual-head motor 120. Mounting base 160 is provided with guide holes 161, which are evenly distributed around the axis of dual-head motor 120. Heat sink 162 is connected between dual-head motor 120 and mounting base 160; A bracket 170 is placed between the fan 130 and the housing 110, and the bracket 170 is movably connected to the fan 130.

[0027] Mounting base 160 is installed inside housing 110 using screws and other fasteners. Dual-head motor 120 is installed on mounting base 160 using screws and other fasteners. Airflow entering through air inlet channel 115 is diverted and guided to the outer wall of dual-head motor 120 after a 180° turn through guide hole 161. Heat sink 162 increases the contact area with air. Heat sink 162 abuts against dual-head motor 120, allowing heat from dual-head motor 120 to be transferred to heat sink 162. Bracket 170 is connected to housing 110 using screws and other fasteners. Fan 130 is connected to bracket 170 via bearing mounting. Bracket 170 improves the stability of fan 130's mounting structure.

[0028] Example 3:

[0029] like Figure 2 , Figure 3 As shown, this application embodiment provides a meat grinder, which, in addition to including the above-mentioned technical features, further includes the clutch assembly 300 comprising: The clutch seat 310 is provided with a first limiting member 311, and the clutch seat 310 is provided with a first clutch pawl 312; The second clutch pawl 131 is installed on the fan 130; Mounting bracket 171 is connected to bracket 170; The rotating base 320 is movably connected to the mounting bracket 171; Connecting seat 330 is connected between clutch seat 310 and rotary seat 320; Connector 340 is connected between the rotating base 320 and the movable cover 140; The output shaft of the dual-head motor 120 is provided with a first limiting groove 121 corresponding to the first limiting member 311. A sleeve seat 350 is provided between the clutch seat 310 and the connecting seat 330 for movable connection. The sleeve seat 350 includes a sleeve plate 351, which is sleeved on the connecting seat 330. The connecting seat 330 is provided with a first spring 352 placed on both sides of the sleeve plate 351. The connecting seat 330 is provided with a second limiting member 331. The mounting bracket 171 is provided with a second limiting groove 172 corresponding to the second limiting member 331. The rotating seat 320 is provided with a first sliding column 321. The connecting seat 330 is provided with a first sliding groove 332 corresponding to the first sliding column 321.

[0030] The clutch seat 310 is movably mounted on one of the output shafts of the dual-head motor 120. The first limiting member 311 corresponds to the first limiting groove 121, allowing the clutch seat 310 and the corresponding output shaft of the dual-head motor 120 to move relative to each other only along the axial direction. The clutch seat 310 is adapted to the second clutch claw 131 of the fan 130 via the first clutch claw 312. The first clutch claw 312 and the clutch seat 310 are connected by fasteners such as screws or integrally connected. The second clutch claw 131 is connected by fasteners such as screws. When the first clutch claw 312 and the second clutch claw 131 are engaged, the dual-head motor 120 drives the fan 130 to rotate, thereby controlling the airflow within the housing 110 during the operation of the main unit 100. The flow path cools the dual-head motor 120. The mounting bracket 171 and the support bracket 170 are connected by screws or other fasteners. The output shaft of the dual-head motor 120 is connected to the support bracket 170 via bearings to improve stability. The rotating seat 320 is hinged to the mounting bracket 171, with the hinge axis aligned with the axis of the clutch seat 310. The connecting piece 340 is integrally connected to the rotating seat 320 and the movable cover 140, or connected by screws or other fasteners, enabling synchronous rotation of the movable cover 140 and the rotating seat 320. The connecting seat 330 is movably connected to the rotating seat 320. The second limiting piece 331 is integrally connected to the connecting seat 330, with the second limiting piece 331 and the second limiting groove 172 working together. This allows the connecting seat 330 and the mounting bracket 171 to move relative to each other only along the axial direction. The first sliding column 321 is interference-fitted onto the rotating seat 320. Through the cooperation of the first sliding column 321 and the first sliding groove 332, the first sliding column 321 can slide and move within the first sliding groove 332. When the movable cover 140 is manually rotated, the rotating seat 320 is controlled to rotate. Through the structure between the rotating seat 320, the mounting bracket 171, and the connecting seat 330, the connecting seat 330 is pushed to move along the axial direction of the dual-head motor 120, moving the clutch seat 310 and realizing the clutch control between the first clutch pawl 312 and the second clutch pawl 131. The socket plate 351 is connected to the socket seat 350. 50 is hinged to the clutch seat 310. The first spring 352 acts on the sleeve plate 351. When the first clutch pawl 312 and the second clutch pawl 131 are engaged, the first spring 352 increases the locking force between the first clutch pawl 312 and the second clutch pawl 131. When the first clutch pawl 312 and the second clutch pawl 131 are separated, the clutch seat 310 abuts against the mounting bracket 171. The first spring 352 improves the structural stability of the clutch seat 310. The first sliding groove 332 is spirally distributed on the side wall of the connecting seat 330, so that the two ends of the stroke of the first sliding column 321 correspond to the fully closed and fully open states between the opening 141 of the movable sleeve and the air inlet 113 and the air outlet 114, respectively.

[0031] Example 4:

[0032] like Figure 2 As shown, this application embodiment provides a meat grinder, which, in addition to including the above-mentioned technical features, further includes the following in the main unit 100: The spiral tube 180 is wound around the outside of the heat sink 162; Pump body 181, mounted on bracket 170; The guide plate 182 is hollow, and the guide plate 182, the spiral tube 180, and the pump body 181 are connected. The pump body 181 and the fan 130 are connected and driven by two gears.

[0033] The pump body 181 operates to drive the flow of cooling water within the spiral tube 180. The cooling water is pure, non-toxic, and harmless. The guide plate 182 is installed at the air inlet channel 115 and near the guide hole 161. The guide plate 182 guides the airflow through a bend, making the airflow smoother. One or two guide plates 182 are provided. The guide plates are connected to the spiral tube 180 and the pump body 181. The hollow structure of the guide plate 182 allows water to circulate. When air flows over the guide plate 182, it cools the cooling water in the water circulation. The spiral tube 180 is wound around the outside of the heat sink 162, improving the cooling effect of the heat sink 162. The above structure further improves the heat dissipation efficiency of the dual-head motor 120.

[0034] Example 5:

[0035] like Figure 2 , Figures 4-7 As shown, this application embodiment provides a meat grinder, which, in addition to including the above-mentioned technical features, further includes the following in the main unit 100: The output base 400 is movably mounted on the bottom cover 112 and connected to the output shaft of the dual-head motor 120. The output base 400 is provided with a mating hole 410 corresponding to the meat grinder 200. The movable connector 420 is movably mounted on the output socket 400; Control valve assembly 430, mounted on movable joint 420, is used to control the flow state of coolant; Two first valve bodies 440 are provided and installed on the output seat 400; The meat grinder 200 has a connector 210 at its end, and the connector 210 is connected to a second valve body 230 corresponding to the first valve body 440. The meat grinder 200 has a water passage 240 connecting the two second valve bodies 230. The connector 210 has a sealing element 250 corresponding to the mating hole 410. The movable joint 420 has two inner ring grooves 421, and the output seat 400 has two outer ring grooves 401. The inner ring grooves 421 and the outer ring grooves 401 are respectively sealed and fitted. The inner ring grooves 421 are respectively connected to the guide plate 182 and the spiral tube 180, and the outer ring grooves 401 are respectively connected to the first valve body 440.

[0036] The movable joint 420 is connected to the guide plate 182 and the spiral tube. The output seat 400 is connected to the bottom cover 112 via a bearing. The output seat 400 is connected to the output shaft of the dual-head motor 120. The mating hole 410 of the output seat 400 is adapted to the meat grinder 200. The rotation of the output seat 400 drives the meat grinder 200 to rotate. The movable joint 420 is hinged to the output seat 400, and its hinge axis is the same as the axis of the dual-head motor 120. The movable joint 420 is connected to the bottom cover 112 via screws or other fasteners. The flow of coolant to the meat grinder 200 is controlled by the control valve assembly 430. The first valve body 440 controls the flow of water to the output seat 400, and the second valve body 230 controls the flow of water to the meat grinder 200. The connector 210 is connected to the meat grinder 200 by thread or welding. The water passage 240 is formed by drilling directly into the meat grinder 200 or by using a thin hose installed inside the meat grinder 200, ensuring the hose is tightly fitted to the inner wall of the meat grinder 200 to prevent wobbling. The first valve body 440 and the second valve body 230 are connected in a corresponding manner. When the control valve assembly 430 introduces cooling water from the water circulation plate into the meat grinder 200, the temperature of the cooling water is higher than that of the frozen meat. This provides a heating temperature of 10-20 degrees Celsius for the frozen meat, improving its grinding efficiency. Furthermore, when grinding frozen meat, the motor load increases significantly, and the heat generation rate of the dual-head motor 120 also increases. The cooling water circulating through the meat grinder 200 has a lower temperature. The heat exchange between the spiral tube 180 and the heat sink 162 can improve the heat dissipation effect of the dual-head motor 120. After the output seat 400 and the movable joint 420 are installed and matched, the inner ring groove 421 and the outer ring groove 401 are matched accordingly, allowing water circulation in and out of the movable joint 420 respectively. The output seat 400 and the movable joint 420 are sealed by a sealing ring. The structure of the inner ring groove 421 and the outer ring groove 401 enables the cooling water to circulate in a relatively active state between the output seat 400 and the movable joint 420.

[0037] Furthermore, the first valve body 440 and the second valve body 230 include: Valve stem 500, equipped with piston 520; The second spring 510 abuts against the valve stem 500; The abutment portion 530 is on the same axis as the valve stem 500, and the abutment portion 530 extends outward along the axis from the valve stem 500 and has a radially outward taper. The abutting portions 530 of the first valve body 440 and the second valve body 230 correspond to each other.

[0038] The valve stem 500 and piston 520 are rigidly connected by welding or threading. The second spring 510 abuts against the valve stem 500 and acts outward on the valve stem 500. The abutting part 530 is integrally connected to the valve stem 500. When the meat grinder 200 mates with the mating hole 410 on the output seat 400, the first valve body 440 and the second valve body 230 correspond to each other, so that the abutting parts 530 of the first valve body 440 and the second valve body 230 abut against each other. Under their interaction, the valve stem 500 is pushed, so that the first valve body 440 and the second valve body 230 are opened, realizing communication.

[0039] Furthermore, the control valve assembly 430 includes: The movable core 431 is movably mounted on the movable connector 420; Electromagnets 432 are respectively placed between the two ends of the movable core 431 and the movable connector 420; The movable core 431 is provided with a groove 433 and a connecting hole 434.

[0040] When the electromagnet 432 is energized, it generates an interaction force. The electromagnet 432 controls the movement of the movable core 431. The groove 433 and the connecting hole 434 are respectively placed at both ends of the movable core 431. When the connection port of the guide plate and the spiral tube connected to the movable joint 420 corresponds to the groove 433, the water flow is controlled to not enter the meat grinder 200 and circulate.
