Because the connecting head contact engagement transmission, the noise and vibration noise of motor as power source are directly transmitted to the cup body, and the rubbing noise in the cup body is superimposed. With the increase of the disassembly times of cup body and main machine, the installation positioning and wear between connecting heads aggravate, which leads to the decrease of the coaxiality of connecting head relative to motor shaft and cutter shaft, and further generates transmission abnormal sound, and the rubbing performance of food processing machine is also affected due to the decrease of coaxiality and rubbing crusher disturbance.

DETAILED DESCRIPTION

[0034] The utility model will be further explained in detail below in combination with the drawings and specific embodiments.

[0035] As Figures 1 to 9 shown, the utility model provides a kind of magnetic drive food processor, including host computer 100, host computer 100 is equipped with by motor 101 driven lower transmission disk 102, the lower transmission disk is connected with motor output shaft transmission, motor 101 directly drives lower transmission disk rotation;Cup assembly 200, including cup 201 and cup cover, cup cover is covered in the upper end of cup, cup lower end is equipped with cup bottom 202, cup bottom is equipped with heating element, as preferred, the cup bottom is equivalent to heating disc, heating element is preferably heating tube embedded in heating disc, for heating the material in cup.The cup bottom is completely closed surface, and the cup bottom center has no through-hole structure, so it is not necessary to set any shaft seal and other sealing structure, compared with the conventional food processor with shaft seal, the utility model provides a kind of cup food processor without shaft seal, can completely avoid the situation of cup bottom water leakage damage motor.

[0036] The cup body is detachably installed on the main unit 100, and the pulverizing device 300 is detachably disposed within the cup body. The pulverizing device includes a pulverizing blade 301, a blade holder housing 302, and an upper permanent magnet 305 disposed within the blade holder housing. A recess 307 is formed on the bottom surface of the blade holder housing 302, and the upper permanent magnet 305 is disposed above the recess 307. The concave surface of the recess is higher than the lowest point of the pulverizing device, causing the upper permanent magnet to be axially away from the plane where the lowest point of the pulverizing device is located. When the pulverizing device is separated from the bottom of the cup and removed from the cup body, and placed on a metal countertop in the kitchen environment such as a sink or kitchen knife that can be attracted by a magnet, the upper permanent magnet is separated from the countertop by the recess. As the magnetic force between the permanent magnet and the attracted object increases with the distance between them, the magnetic attraction force decreases exponentially. Therefore, the isolation provided by the recess 307 can significantly weaken the adsorption force between the upper permanent magnet and the metal tabletop, allowing the user to easily remove the pulverizing device from the metal tabletop without the need for additional prying tools, making the operation effortless and convenient. When the pulverizing device 300 is installed at the bottom of the cup, the recess 307 extends the contact area between the pulverizing device and the bottom of the cup in terms of height. In particular, the side of the recess can form an air gap between the pulverizing device and the cup body. Due to its own gravity, the liquid is distributed on the bottom surface, thus preventing water from accumulating in the air gap and effectively preventing the pulverizing device from being difficult to separate from the bottom of the cup after pulverization.

[0037] This embodiment provides a specific implementation method one, such as... Figures 1 to 5 As shown, a magnetically driven food processor includes a main unit with a lower drive disk 102 driven by a motor inside the main unit. The lower drive disk includes a lower disk body 103 and a lower permanent magnet 104 disposed on the lower disk body. A cup assembly includes a cup body and a cup lid, with a cup bottom at the lower end of the cup body. The cup body is detachably installed in the main unit. A pulverizing device is detachably disposed in the cup body. The pulverizing device includes a pulverizing blade 301, a blade holder housing 302, and an upper permanent magnet 305 disposed in the blade holder housing. A recess 307 is formed on the bottom surface of the blade holder housing. The upper permanent magnet is disposed above the recess, and the concave surface of the recess is higher than the lowest point of the pulverizing device. The bottom of the cup protrudes upward to form a boss 203 that matches the recess. After the cup body is installed on the main unit and the crushing device is installed at the bottom of the cup, the upper end of the lower drive disk 102 is located inside the boss. The boss 203 extends into the recess so that the upper permanent magnet and the lower drive disk are close together. This arrangement maximizes the magnetic attraction between the upper permanent magnet 305 and the lower drive disk 102, ensuring that the torque driven by the motor can be reliably transmitted to the crushing device 300, thereby efficiently crushing and processing the material inside the cup.

[0038] When the crushing device 300 is separated from the cup body 201, the recess can weaken the magnetic attraction between the upper permanent magnet in the crushing device and the kitchen metal countertop, making it easier for the user to remove the crushing device. When the crushing device 300 is installed on the cup bottom and mounted on the main machine together with the cup body, the upper end of the lower transmission disk can just pass through the cup bottom and extend into the boss 203, and the boss extends into the recess, so that the upper permanent magnet 305 and the lower permanent magnet 104 on the lower transmission disk 102 are as close as possible, thereby meeting the strong magnetic attraction and strong transmission torque, solving the problem that the crushing device is easily attracted to the kitchen metal countertop and is difficult to remove due to excessive magnetic attraction of the permanent magnet, and the double problems of large transmission torque loss and low transmission efficiency caused by the excessive distance between the crushing device placed on the cup bottom and the lower transmission disk, resulting in exponential reduction of magnetic attraction. In addition, when the crushing device reaches a speed of 9000 rpm or above, it can still run smoothly, the bottom surface of the knife seat shell can be firmly matched with the cup body and form a stable suction force between the lower transmission disk, ensuring torque transmission and smooth operation of the crushing knife, especially when the material is stuck, the knife seat shell can still maintain stable adsorption to enable the stuck part to be cut into small pieces and then crushed into fine particles. Figure 3 and Figure 5 As shown in the figures, the inner recess depth of the recess 307 is H1, H1≥1mm, the height of the boss 203 protruding upward is H2, H2≥1mm, the distance between the top surface of the recess and the bottom surface of the knife seat shell is H3, H3≥2mm, in this embodiment, H1 is 2mm, H2 is 2.5mm, and H3 is 2.4mm. The distance between the upper permanent magnet above the recess and the horizontal metal countertop is obviously greater than 2mm, which can effectively avoid strong adsorption and difficult removal of the crushing device, while ensuring that the boss has sufficient height to effectively extend into the recess, so that the lower transmission disk is close enough to the upper permanent magnet, ensuring strong magnetic attraction between the crushing device installed on the cup bottom and the lower transmission disk.

[0039] The projection of the upper permanent magnet 305 on the horizontal plane at least partially overlaps with the projection of the recess 307 on the horizontal plane, which means that the upper permanent magnet and the recess at least partially overlap in the vertical direction, so that the recess can effectively isolate the distance between the upper permanent magnet and the horizontal plane. When the projection of the upper permanent magnet 305 on the horizontal plane is greater than the projection of the recess 307 on the horizontal plane or they partially intersect, the upper permanent magnet is at least partially located outside the recess. At this time, the upper permanent magnet whose projection is located within the recess can be effectively isolated by the recess, and the upper permanent magnet outside the recess can partially strengthen the transmission of torque. In addition, it also expands the form structure of the upper permanent magnet, which can be completely above the recess, can be above the recess within the range covered by the recess, and the upper permanent magnet outside the uncovered recess, which is equivalent to the upper permanent magnet 305 above the recess, can be partially arranged downward, thereby being closer to the lower transmission disk on the outer periphery of the recess. The magnetic attraction of the downwardly extending part of the upper permanent magnet is limited, and since most of the upper permanent magnet has been isolated by the recess, the user can still easily remove the crushing device when it is placed on the kitchen metal table. It can be understood that the downwardly extending part of the upper permanent magnet can also cooperate with the lower attracting magnet arranged in the cup to adsorb the crushing device, preventing the crushing device from falling from the bottom of the cup when pouring.

[0040] As a preferred, the projection of the recess on the horizontal plane completely covers the projection of the upper permanent magnet on the horizontal plane, and the upper permanent magnet is preferably located directly above the recess. When the crushing device is in a separated state from the cup, the recess can completely separate the upper permanent magnet from the metal table in the kitchen environment. The diameter of the lower transmission disk is smaller than the diameter of the boss, and when the crushing device is placed on the bottom of the cup, the upper end of the lower transmission disk completely extends into the boss and the boss extends into the recess, which can make the lower permanent magnet of the lower transmission disk and the upper permanent magnet be arranged in close contact, and does not waste the magnetic attraction area that can be matched by the upper permanent magnet and the lower transmission disk. The space between the upper permanent magnet and the lower transmission disk is maximized, which does not weaken the strong torque transmission in the working state, and ensures that the upper end surface of the lower transmission disk can completely extend into the recess and be in close contact with the upper permanent magnet to form a strong magnetic attraction when the crushing device is in an assembled state with the cup.

[0041] Specifically, the tool seat shell 302 comprises an upper shell 303 and a lower shell 304, the upper shell and the lower shell form an inner cavity, the upper permanent magnet is arranged in the inner cavity, and the recess is arranged in the lower shell. Preferably, the upper shell comprises an integral top wall and side wall, the lower shell constitutes the bottom surface of the tool seat shell, and the lower shell is sealingly connected to the lower end of the upper shell by welding. The upper end of the upper shell is sealingly and drivingly connected to the cutter shaft by a shaft seal, so that a closed and sealed inner cavity is formed in the tool seat shell. The cup bottom is further provided with a sunken platform 204, the sunken platform comprises a sunken platform bottom surface 206 and a sunken platform side surface 205, the boss 203 is arranged on the sunken platform bottom surface, and the tool seat shell is at least partially located in the sunken platform to limit the installation of the crushing device. When the cutter rotates at high speed to crush the material and encounters large pieces of material, the tool seat shell is prone to radial swing due to uneven circumferential stress. The sunken platform can limit the side wall of the tool seat shell to prevent the tool seat shell from swinging or tilting radially. The cutter further rotates to crush the large pieces of material into small pieces of material and then into granular material, and the circumferential stress of the cutter is basically restored. The sunken platform 204 cooperates with the tool seat shell 302 to prevent the crushing device from being separated from the cup bottom, thereby maintaining the distance between the upper permanent magnet and the lower driving magnetic disk and the strong attractive magnetic force, thereby ensuring the strong driving torque. Preferably, more than two-thirds of the side wall of the tool seat shell is located in the sunken platform 205. Preferably, the depth of the sunken platform is H, H≥8mm, and in the embodiment, H is 11.3mm, which effectively limits the tool seat shell and has good cup bottom strength, and the crushing device is not prone to tilting. Preferably, the tool seat shell is provided with an anti-rotation structure to prevent the tool seat shell from rotating with the upper permanent magnet and the cutter. Specifically, the anti-rotation structure can be a flat position, a groove or a protrusion arranged on the tool seat shell, and the anti-rotation structure cooperates with the sunken platform of the cup bottom.

[0042] The diameter of the sunken platform bottom surface 206 is greater than the diameter of the boss 203, so that an annular groove 207 is formed between the sunken platform side surface and the boss. The bottom surface of the tool seat shell is provided with a limiting structure 308 around the recess, and the limiting structure cooperates with the annular groove 207. Specifically, the recess is formed on the bottom surface of the tool seat shell, and a ring platform is formed on the outer periphery of the recess which is not recessed, that is, the limiting structure. When the crushing device is installed in the cup bottom, the ring platform extends into the annular groove, so that the crushing device can stably cooperate with the boss of the cup bottom without deviation when the cutter is crushing at high speed.

[0043] The pulverizing device further comprises a cutter shaft, i.e. a transmission shaft 334, which is connected with the pulverizing cutter and the upper permanent magnet respectively. Specifically, the pulverizing device comprises a disc body 306, and the upper permanent magnet is mounted on the disc body 306. Specifically, the disc body is in the shape of a cover, and the lower end of the disc body is provided with a mounting position for mounting the upper permanent magnet. The upper end of the disc body is fixedly connected with the lower end of the cutter shaft in an integral manner. A gap is provided between the upper permanent magnet 305 and the upper surface of the recess 307 to prevent scraping and abrasion between the upper permanent magnet and the upper surface of the recess and to prevent abnormal noise. The bottom center of the disc body is provided with a mounting groove 309, and a bearing 310 is arranged in the mounting groove. The center of the recess is protruded upward to form a protrusion 311, and the top end of the protrusion is preferably abutted against the bearing to form a point contact support for the lower end of the upper permanent magnet, which can optimize the dynamic balance of the upper permanent magnet without increasing noise.

[0044] The cutter seat shell is further provided with an upper suction magnet 312, and the cup body is provided below with a lower suction magnet 210 which is in suction cooperation with the upper suction magnet. The upper suction magnet 312 is arranged on the outer circumferential side of the recess, and the lower suction magnet 210 is arranged in the cup body. When the pulverizing device is mounted on the cup bottom, the lower suction magnet is in suction cooperation with the cup body. When the cup body is separated from the main machine, the upper permanent magnet and the lower transmission disk are separated at any time. The pulverizing device can be adsorbed on the cup bottom by the upper and lower suction magnets to prevent the pulverizing device from falling out of the cup body when liquid is poured. When the cup body and the pulverizing device are mounted in place, the upper and lower suction magnets are in mutual suction to assist the effective suction between the upper permanent magnet and the lower transmission disk, thereby preventing the pulverizing device from being lifted by food during processing. Specifically, the disc body is in the shape of a cover with an open lower end, and the disc body top wall is integrally formed with the lower end of the cutter shaft. The disc body top wall extends downwardly and is provided with a plurality of partitions which are arranged at intervals and form mounting positions for mounting the upper permanent magnet in the interval spaces. The outer periphery of the disc body is provided with an iron ring 328 which comprises a longitudinal ring wall and a transverse ring wall connected with the bottom end of the longitudinal ring wall to form a mounting position for mounting the upper suction magnet between the longitudinal ring wall and the transverse ring wall. The upper suction magnet is in the shape of a ring and is arranged around the disc body periphery of the upper permanent magnet with the iron ring. Preferably, the iron ring and the upper suction magnet are fixedly arranged and are arranged separately from the upper permanent magnet and the disc body to avoid being driven to rotate by the upper permanent magnet.

[0045] It can be understood that the embodiment provides another cup bottom structure of the cup body and a cooperation scheme of the pulverizing device and the cup bottom. Specifically, the cup bottom comprises a cup bottom bottom surface 208 and a cup bottom side surface 209 which is connected with the side wall of the cup body, as shown in the cup bottom side surface and the side wall of the cup body in Figure 6 The protrusion is arranged on the cup bottom bottom surface in the embodiment, and the cup bottom side surface is cooperated with the side surface of the cutter seat shell to limit the mounting of the pulverizing device. Such arrangement further simplifies the structure of the cup bottom, and cleaning is more convenient, complete and without cleaning dead angle.

[0046] The embodiment also provides a structure-optimized crushing device 300 and a food processor using the crushing device, the food processor comprising a cup assembly 200 and the crushing device 300, the crushing device being detachably arranged at the cup bottom 202, the crushing device comprising a crushing blade 301, a blade seat housing 302, and a permanent magnet arranged in the blade seat housing, i.e. the upper permanent magnet 305 in the drawing, the permanent magnet driving the crushing blade 301 to rotate through a transmission shaft, i.e. the blade shaft of the crushing device. The blade seat housing 302 integrally forms a mounting cavity 313 for mounting a shaft seal and a bearing, the mounting cavity being provided with a through hole surrounded by a flange 327 at the upper end of the mounting cavity, so that the transmission shaft passes through the mounting cavity 313 from bottom to top and is connected with the shaft seal and the bearing respectively, without the need to arrange an additional blade holder to mount and fix the crushing blade, and the transmission, mounting, sealing, and positioning of the crushing blade are realized through the integral structure of the blade seat housing. Since the food processor is driven by a magnet, the cup bottom does not need to be provided with a transmission hole, so that the food processor cup is realized without a shaft seal and without water leakage. Since the blade seat housing does not rotate with the crushing blade, the mounting cavity integrally arranged on the blade seat housing is arranged to realize the magnetic drive transmission of the crushing blade. The blade seat housing 302 comprises a side wall and a bottom wall, the lower end of the side wall of the blade seat housing being fixed to the bottom wall by welding, so that a closed cavity is formed in the blade seat housing, and the processed material in the cup will not enter the crushing device. The mounting cavity comprises a shaft seal mounting cavity 314 and a bearing mounting cavity 315, and the shaft seal mounting cavity and the bearing mounting cavity are provided with an annular step 318 at the communication position, and the bearing is abutted on the step face of the annular step to be axially limited. As a preferred embodiment, a gasket 319 is arranged between the bearing and the annular step, the upper end of the bearing is abutted on the annular step through the gasket, and the lower end of the bearing is provided with a limiting snap spring 320 to limit the lower end of the bearing, and two bearings are preferably arranged in the mounting cavity to sufficiently ensure the coaxiality and transmission stability of the transmission shaft.

[0048] As Figure 7As shown, as one of the embodiments of the crushing device, the top wall and the side wall of the cutter seat housing 302 are integrally arranged, the top wall of the cutter seat housing extends upward and downward to form an upper surrounding edge 316 and a lower surrounding edge 317, respectively, the flange 327 is arranged at the top end of the upper surrounding edge, and the upper surrounding edge and the lower surrounding edge are arranged in communication and form the mounting cavity 313 with the flange, thereby avoiding the separate arrangement of the cutter holder for mounting the transmission shaft and the crushing knife, greatly simplifying the structure of the crushing device, and effectively improving the coaxiality of the crushing knife, the upper permanent magnet, and the lower transmission magnetic disk, without abnormal sound in the processing process, lower crushing noise, small disturbance of the crushing knife, and higher crushing efficiency.

[0049] As shown in FIG. 1, Figure 3 As shown, as another embodiment of the crushing device, the structure of the cutter seat housing 302 is further simplified and miniaturized, the side wall of the cutter seat housing is arranged upwardly inclined, and the upper end of the side wall of the cutter seat housing is directly connected with the flange 327, without the top wall of the cutter seat housing, thereby miniaturizing the whole crushing device, and the cavity enclosed in the cutter seat housing has better sealing performance and is not easily affected by thermal expansion and cold contraction, thereby further prolonging the service life of the shaft seal.

[0050] The optimized crushing device can be applied to the food processor in the embodiment, which includes a main machine and a cup body. The main machine and the cup body are arranged in a detachable manner. The main machine is provided with a motor and a lower transmission magnetic disk directly connected with the motor shaft. After the cup body and the crushing device are installed in place, the upper permanent magnet in the crushing knife seat is attracted to the lower transmission magnetic disk and drives the crushing knife to rotate through the motor.

[0051] It can be understood that the crushing device can also be adapted to other forms of food processors. Specifically, the food processor includes a main machine and a cup body. The main machine and the cup body are arranged in an integral and non-detachable manner. The main machine is provided with a lower transmission magnetic disk for driving the upper permanent magnet.

[0052] It can be understood that the optimized crushing device can also be adapted to other forms of food processors. Specifically, the food processor includes a main machine and a cup body detachably connected to the main machine. The cup body is provided with the crushing device. The cup seat of the cup body is provided with a motor and a lower transmission magnetic disk.

[0053] It can be understood that the optimized crushing device drives the crushing knife to rotate as the motor rotor itself cooperates with the stator assembly in the cup seat of the cup body or the main machine.

[0054] The embodiment also provides a second embodiment, as shown in FIG. 2, Figures 6 to 9As shown, the embodiment provides a magnetic transmission food processor easy to clean, including a host 100, cup assembly 200 and crushing device 300, the host is provided with a lower transmission disk 102 driven by a motor, the cup assembly includes a cup 201 and a cup cover, the lower end of the cup is provided with a cup bottom 202, the cup is detachably mounted on the host, the crushing device 300 is separably arranged in the cup 201, the crushing device 300 includes a crushing knife 301, a knife seat shell 302 and an upper permanent magnet 305 arranged in the knife seat shell, the bottom surface of the knife seat shell is concave to form a downward protruding annular support platform around the recess, preventing the knife seat shell from being deformed upward due to heat, causing friction noise with the upper permanent magnet. The upper permanent magnet 305 is arranged above the recess, the cup bottom 202 is provided with a continuous cup bottom plane, the bottom surface of the knife seat shell 302 is in contact with the cup bottom plane to make the cup bottom plane and the recess 307 fit clearance, when the crushing device and the cup are in a separated state, placed on the kitchen metal countertop, the recess can form an isolation space to avoid the upper permanent magnet from being adsorbed too tightly with the metal countertop, the recess 307 weakens the adsorption force of the upper permanent magnet 305 to the metal countertop, the user can easily remove the crushing device from the metal countertop, and the adsorption of the lower permanent magnet of the lower transmission disk 102 and the upper permanent magnet requires magnetic force according to the design margin of the processing condition, so as to meet the transmission torque while avoiding the crushing device 300 from being adsorbed on the kitchen metal countertop, and simplifying the bottom surface structure of the cup. At the same time, the cup is a continuous plane, the bottom surface of the crushing device can be better arranged with the bottom surface plane of the cup bottom, and the recess 307 can effectively form an air gap, solving the problem that the bottom surface of the crushing device 300 and the cup bottom plane are filled with residual slurry after the food processor is processed and the slurry is poured out, causing the crushing device to be adsorbed on the cup bottom plane and difficult to remove.

[0055] The cooperation between the bottom of the pulverizing device 300 and the bottom of the cup is optimized, the structure of the cup bottom is simplified, and the cup bottom is less likely to retain slurry and food residues, and is easier to clean. As a preferred, the projection of the upper permanent magnet on the horizontal plane at least partially overlaps the projection of the recess on the horizontal plane, so that the recess 307 can effectively isolate the distance between the upper permanent magnet 305 and the horizontal plane. When the projection of the upper permanent magnet 305 on the horizontal plane is greater than the projection of the recess 307 on the horizontal plane or they partially intersect, the upper permanent magnet 305 is at least partially located outside the recess. At this time, the upper permanent magnet located in the recess can effectively isolate the magnetic force through the recess, and the upper permanent magnet located outside the recess can partially strengthen the transmission of torque. In addition, the shape and structure of the upper permanent magnet 305 are also expanded. It can be completely above the recess, it can be above the recess within the range covered by the recess, and the upper permanent magnet outside the recess can be partially extended downward. Of course, the projection of the upper permanent magnet on the horizontal plane can completely cover the projection of the recess on the horizontal plane. At this time, the surface of the upper permanent magnet close to the lower transmission disk is large enough, and the area space cooperating with the lower transmission disk is large. Through the surface magnetic design margin adjustment of the lower transmission disk, it can not only prevent the user from easily removing the pulverizing device on the kitchen metal table, but also ensure strong magnetic attraction and strong torque transmission, and the cup is easy to clean.

[0056] Specifically, in the embodiment, the recesses include a first recess 321 arranged in the middle of the bottom surface of the tool holder shell, the diameter of the upper permanent magnet is greater than the diameter of the first recess 321, and a first gap 323 is arranged between the first recess and the cup bottom plane. The recesses also include a second recess 322 arranged on the bottom surface of the tool holder shell and away from the middle. The first recess and the second recess form a downwardly protruding annular support platform 326. The heating element is arranged at the bottom of the cup body. The annular support platform can effectively reduce the contact heating area of the tool holder shell and the cup bottom. Since the bottom surface of the tool holder shell is preferably arranged to cover the entire cup bottom, the arrangement of the annular boss can strengthen the heat resistance of the bottom surface of the tool holder shell and avoid friction noise caused by contact with the permanent magnet. The second recess and the cup bottom plane are provided with a second gap 324. The cup body is provided with a cup body side wall connected with the cup body and matched with the side surface of the tool holder shell. The third gap 325 is arranged between the cup body side wall and the side surface of the tool holder shell. The first gap 323 and the second gap 324 are not connected with each other. The second gap 324 and the third gap 325 are arranged in communication. The third gap can effectively form an air gap to avoid the pulverizing device being adsorbed on the cup bottom plane and being difficult to remove. The communication between the second gap and the third gap can allow external air to quickly pass through the gap and enter between the cup bottom and the bottom surface of the tool holder shell, thereby further facilitating the user to quickly remove the pulverizing device from the cup body. The upper isolation gap is arranged between the upper permanent magnet and the bottom surface of the tool holder shell. The lower transmission disk is arranged below the cup bottom plane. The isolation gap is arranged between the lower transmission disk and the cup bottom plane. The upper permanent magnet, the lower transmission disk, the bottom surface of the tool holder shell, the first gap and / or the second gap, the cup bottom plane and the isolation gap are sequentially arranged. As much as possible, the structure in the axial space can be intensive based on the recess space, and the disassembly between the pulverizing device and the cup body is simplified. It should be noted that when the pulverizing device is placed on the cup bottom, the second gap and the third gap are arranged in communication to facilitate extraction, preventing the bottom surface of the tool holder shell from being too full of slurry between the cup bottom to be adsorbed on the cup bottom and difficult to remove. When the pulverizing device is placed on the kitchen horizontal metal table, the first recess and the second recess both play a role in isolating the axial space, avoiding the tool holder shell being adsorbed on the metal table and being difficult to remove, and the user does not need to use external force or additional tools to separate the pulverizing device.

[0057] The lower transmission disk comprises a lower disk body 103 and a lower permanent magnet 104 arranged on the lower disk body, the lower disk body is provided with an upper opening mounting groove 309, and the lower permanent magnet 104 is fixedly arranged in the mounting groove and exposed on the upper end surface of the lower permanent magnet, so that the loss of surface magnetic field is minimized. The tool seat shell 302 comprises an upper shell 303 and a lower shell 304, the lower shell constitutes the bottom surface of the tool seat shell 302, the middle part of the top wall of the upper shell 303 is provided with a through hole, the edge of the through hole extends upward and downward respectively to form a mounting cavity 313, the mounting cavity 313 is provided with a shaft seal and a bearing for the tool shaft to pass through, the upper part of the tool shaft is exposed outside the tool seat shell and connected with the crushing knife, and the lower part of the tool shaft is closed in the tool seat shell and connected with the upper permanent magnet, so that the crushing knife can be reliably driven by the permanent magnet, and the transmission noise is low.

[0058] The embodiment also provides a third implementation manner, and the food processor comprises a main machine 100, a cup assembly 200 and a crushing device 300, the main machine is provided with a lower transmission disk driven by a motor, the cup assembly comprises a cup and a cup cover, the lower end of the cup is provided with a cup bottom, the cup is detachably installed on the main machine, the crushing device is detachably arranged in the cup, the crushing device comprises a crushing knife 301, a tool seat shell 302 and an upper permanent magnet 305 arranged in the tool seat shell, Figure 8 and Figure 9 As shown in the figure, the bottom surface of the tool seat shell is downwardly protruded to form an annular support table, the upper permanent magnet is arranged above the support table, the bottom end of the support table 326 is the lowest point of the bottom surface of the tool seat shell, and the upper permanent magnet is arranged to be separated from the kitchen table top by the support table 326, so that the kitchen metal table top is prevented from being adsorbed. In addition, the support table is actually a structure formed by the protrusion of the bottom surface of the tool seat shell, and a heating device is arranged at the lower end of the cup or the cup bottom. When the heating device is heated at a high power, the bottom surface of the tool seat shell is easily deformed due to heat, which causes interference with the upper permanent magnet. The annular support table can enhance the heat deformation resistance of the bottom surface of the tool seat shell, so that the tool seat shell is prevented from being deformed to interfere with the upper permanent magnet and produce friction noise due to contact.

[0059] The bottom surface of the cutter seat housing of the food processor is protruded downward to form an annular support platform, the upper permanent magnet is arranged above the annular support platform, and the upper permanent magnet is axially away from the plane where the lowest point of the crushing device is located, that is, the lowest point of the annular support platform. When the crushing device is separated from the cup bottom and taken out from the cup body and placed on a metal platform in the kitchen environment which can be magnetically attracted, such as a sink, a kitchen knife, etc., the upper permanent magnet is isolated from the platform by the support platform. Since the magnetic force between the permanent magnet and the attracted object decreases exponentially as the distance between them increases, the isolation of the support platform can greatly weaken the attraction force between the upper permanent magnet and the metal platform, and the user can easily remove the crushing device from the metal platform without the need for additional lifting tools. The operation is labor-saving and convenient. When the crushing device is installed on the cup bottom in the cup body, the support platform can extend the fitting area of the crushing device and the cup bottom in height, and in particular, the side surface of the support platform can form a local small air gap between the cup body, so that the liquid is distributed on the bottom surface due to its own gravity, thereby avoiding water storage in the air gap and effectively avoiding the local attraction between the crushing device and the cup bottom after the completion of the pulp making.

[0060] The cup bottom is provided with a continuous and smooth plane, and the plane is supported and matched with the support platform 326 to form a lower isolation gap 339 between the bottom surface of the cutter seat housing and the plane. The arrangement of the support platform can keep the bottom surface of the cutter seat housing undeformed, thereby keeping the gap value of the lower isolation gap stable and consistent, and the upper permanent magnet is less likely to deform between the cutter seat housing under high-temperature working conditions, thereby fully avoiding abnormal noise. An upper isolation gap 338 is provided between the upper permanent magnet 305 and the bottom surface of the cutter seat housing 302, and the projection of the upper permanent magnet on the horizontal plane at least partially covers the projection of the support platform on the horizontal plane. The downward protrusion of the support platform can further increase the space of the upper isolation gap, thereby avoiding the axial micro-movement of the upper permanent magnet in the crushing device under high-speed working conditions, which can cause wear between the bottom surface of the cutter seat housing and the upper permanent magnet and generate abnormal noise. The projection of the upper permanent magnet on the horizontal plane at least partially covers the projection of the support platform on the horizontal plane, and preferably covers the projection of the support platform on the horizontal plane. This arrangement can fully maintain the stability of the upper isolation gap. It can be understood that the projection of the support platform and the upper permanent magnet on the horizontal plane at least partially overlaps, and preferably the projection of the upper permanent magnet on the horizontal plane partially covers the projection of the support platform on the horizontal plane. Further increasing the coverage area of the upper permanent magnet can ensure smooth and reliable torque transmission.

[0061] As an embodiment of the cup bottom, the cup bottom is provided with a groove matched with the support platform 326. The groove is formed by partially recessing the cup bottom downward, and the support platform is arranged in the groove from top to bottom, so that the upper permanent magnet is arranged close to the lower transmission magnetic disk, and the crushing device is radially limited.

[0062] As another embodiment of the cup bottom, preferably the cup bottom is upwardly convex to form a convex platform 203, and the support platform is arranged in correspondence with or offset from the convex platform in the up-down direction. This arrangement can further ensure the stability of the lower isolation gap space while ensuring the upper isolation gap, and can effectively avoid the upper surface of the lower transmission magnetic disk from being abraded and generating abnormal noise with the lower surface of the cup bottom when the lower transmission magnetic disk has a slight axial excursion. Preferably, the support platform is offset from the convex platform. As shown in Figure 8 The cup bottom is further provided with a sunken platform 204, which includes a sunken platform bottom surface and a sunken platform side surface. The cutter seat shell is at least partially located in the sunken platform to limit the installation of the crushing device.

[0063] As can be understood, as shown in Figure 6 The cup bottom can also be structured as follows: the cup bottom includes a cup bottom bottom surface and a cup bottom side surface, the cup bottom side surface is connected with the side wall of the cup body, and the cup bottom side surface cooperates with the side surface of the cutter seat shell to limit the installation of the crushing device, so that the area of the cup bottom is larger and the anti-thermal deformation effect of the annular support platform of the cutter seat shell is more significant. The crushing device includes a disc body 306, a cutter shaft, and an upper permanent magnet 305 fixedly arranged on the disc body. The cutter shaft is integrally formed with the disc body. The disc body is provided with a permanent magnet mounting groove for mounting the upper permanent magnet, so that the upper permanent magnet is driven to rotate together with the disc body and drives the crushing knife to rotate. The crushing device includes a disc body, a cutter shaft, and an upper permanent magnet 305 fixedly arranged on the disc body. The cutter shaft is integrally formed with the disc body. The disc body is provided with a mounting groove for mounting the permanent magnet. The cutter shaft of the crushing knife is a transmission shaft 335 integrally formed with the disc body, as shown in Figure 4 The transmission shaft includes a first shaft shoulder 335 and a second shaft shoulder 336 from the bottom to the top. The first shaft shoulder 335 is arranged in the cutter seat shell and abuts against the lower end surface of the bearing for supporting the transmission shaft. The second shaft shoulder 336 abuts against the lower end surface of the crushing knife to axially limit the crushing knife, preventing the crushing knife from being axially displaced under the action of the material during high-speed rotation. The bottom center of the magnetic disk body is provided with a mounting groove 309, and the mounting groove is provided with a bearing 310. The center of the bottom surface of the cutter seat shell 302 is upwardly convex to form a convexity, which abuts against the bearing, further maintaining the dynamic balance of the lower end of the permanent magnet, and further optimizing the sound quality of the food processor.
