Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly to a grinding assembly and a food processing device. Background Art

[0002] For food crushers on the market, taking a wall breaker as an example, generally, the form of blade crushing is mostly used to crush food. However, there are at least the following problems with the form of blade crushing: 1. The rotation speed of the blade is high and the noise is large; 2. The thickness of the blade edge can usually only reach 0.05 mm, which limits the fineness of food crushing; 3. The blade edge is easy to become blunt after multiple uses, affecting the fineness of crushing; 4. The cyclic crushing effect of blade crushing is poor, and there is a problem of incomplete crushing for large particle foods. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the related art. For this purpose, the present invention provides a grinding assembly, which can improve the fineness of food crushing.

[0004] An embodiment of the present invention further provides a food processing device.

[0005] In a first aspect embodiment of the present invention, a grinding assembly is provided, including a crushing device. The crushing device includes a first static grinding disc and a dynamic grinding disc group. The dynamic grinding disc group is rotatably arranged in the first static grinding disc. A first grinding part is formed on the outer side wall of the dynamic grinding disc group, and a second grinding part is formed on the inner side wall of the first static grinding disc.

When the dynamic grinding disc group rotates relative to the first static grinding disc, a comprehensive effect such as strong and reciprocating hydraulic shear, friction, centrifugal extrusion, liquid flow collision, and cavitation effect of instantaneous bubble collapse can be formed between the first grinding part and the second grinding part on the food material, so as to realize the crushing of the food material. At the same time, since the crushing of the food material mainly relies on the first grinding part and the second grinding part, the disadvantages brought by mainly crushing the food material by a crushing knife in the related art can be avoided. For example, through the cooperation of the first grinding part and the second grinding part, the problem of large noise caused by the rotation of the blade can be solved, and the use frequency of the blade can be reduced, thereby reducing the possibility of blade passivation. When the food material is thrown out, due to the continuous high-speed rotation of the dynamic grinding disc group, a certain negative pressure will be formed inside the dynamic grinding disc group, and the thrown-out food material can be sucked into the dynamic grinding disc group again. After being crushed and extruded twice by the first grinding part and the second grinding part, it is thrown out of the dynamic grinding disc group and the first static grinding disc again. In this way, a cycle can be formed in the food processing equipment, ensuring that the food material can be crushed and ground multiple times, thereby realizing the complete crushing of the food material and ensuring the fineness of the crushing of the food material.

At the same time, since the crushing of the food material mainly relies on the first grinding part and the second grinding part, the disadvantages brought by mainly crushing the food material by a crushing knife in the related art can be avoided.

In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0075] Please refer to Figures 1 to 17 , the embodiments of the present invention provide a grinding assembly. The grinding assembly mainly includes a crushing device for crushing food ingredients. Taking the application of this grinding assembly in a wall breaker as an example, the wall breaker includes a cup body 10. Among them, the crushing device extends into the cup body 10 to complete the crushing of the food ingredients in the cup body 10.

[0076] Please continue to refer to Figures 1 to 17 , in the embodiments of the present invention, the crushing device includes a stationary first static grinding disc 100 and a dynamic grinding disc group 102 that can rotate relative to the first static grinding disc 100.

[0077] The moving grinding disc group 102 is rotatably arranged in the first stationary grinding disc 100 relative to the first stationary grinding disc 100. Among them, the cross-sectional shape of the first stationary grinding disc 100 is generally circular. Correspondingly, the overall cross-sectional shape of the moving grinding disc group 102 is also circular. The reason for such a setting is that since the moving grinding disc group 102 needs to rotate relative to the first stationary grinding disc 100, the moving grinding disc group 102 with a circular cross-sectional shape has stronger rotational balance and more stable rotation.

[0078] Of course, in some other embodiments, according to actual usage requirements, the cross-sections of the moving grinding disc group 102 and the first stationary grinding disc 100 can also be set into other shapes.

[0079] It can be understood that in the embodiment of the present invention, by rotating the moving grinding disc group 102 relative to the first stationary grinding disc 100, actions such as shearing, extrusion, impact, and relative friction can occur between the moving grinding disc group 102 and the first stationary grinding disc 100, thereby realizing the crushing of food ingredients.

[0080] As described above, in the embodiment of the present invention, in order to achieve the above-mentioned purpose of crushing food ingredients, a first grinding part 104 extending along the height direction of the moving grinding disc group 102 is arranged on the outer side wall of the moving grinding disc group 102. Among them, there are multiple first grinding parts 104, and the multiple first grinding parts 104 are circumferentially spaced along the outer side wall of the moving grinding disc group 102.

[0081] A second grinding part 106 extending along the height direction of the first stationary grinding disc 100 is arranged on the inner side wall of the first stationary grinding disc 100. Among them, there are multiple second grinding parts 106, and the multiple second grinding parts 106 are circumferentially spaced along the inner side wall of the first stationary grinding disc 100.

[0082] In this way, when the moving grinding disc group 102 rotates relative to the first stationary grinding disc 100, a strong and reciprocating comprehensive effect such as hydraulic shear, friction, centrifugal extrusion, liquid flow collision, and cavitation effect of instantaneous bubble collapse can be formed between the first grinding part 104 and the second grinding part 106, realizing the crushing of food ingredients.

[0083] At the same time, since in the embodiment of the present invention, the crushing of food ingredients mainly relies on the first grinding part 104 and the second grinding part 106, the disadvantages brought about by mainly crushing food ingredients by a crushing knife in the related art can be avoided. For example, through the cooperation of the first grinding part 104 and the second grinding part 106, the problem of large noise generated by the rotation of the blade can be solved, and the usage frequency of the blade can be reduced, thereby reducing the possibility of blade passivation.

[0084] According to an embodiment of the present invention, the rotational speed of the moving grinding disc group 102 ranges from 500 revolutions per second to 1600 revolutions per second. Of course, the rotational speed of the moving grinding disc group 102 can also be flexibly set according to different food ingredients.

[0085] Refer to Figure 1 , in the embodiment of the present invention, the first stationary grinding disc 100 is spaced from the cup body 10, that is, a fifth gap is formed between the first stationary grinding disc 100 and the cup body 10. In this way, when the moving grinding disc group 102 rotates relative to the first stationary grinding disc 100, the food ingredients between the moving grinding disc group 102 and the first stationary grinding disc 100 are crushed and extruded by the first grinding part 104 and the second grinding part 106, and under the action of the centrifugal force provided when the moving grinding disc group 102 rotates, can be thrown out of the moving grinding disc group 102 and the first stationary grinding disc 100, and the thrown-out food ingredients can enter the cup body 10 through the fifth gap.

[0086] Refer to Figure 17 , after the food ingredients are thrown out, due to the continuous high-speed rotation of the moving grinding disc group 102, a certain negative pressure will be formed inside the moving grinding disc group 102, and the thrown-out food ingredients can be sucked into the moving grinding disc group 102 again, and after being secondarily crushed and extruded by the first grinding part 104 and the second grinding part 106, are thrown out of the moving grinding disc group 102 and the first stationary grinding disc 100 again. In this way, a cycle of food ingredients can be formed in the grinding assembly, ensuring that the food ingredients can be crushed and ground multiple times, and thus achieving complete crushing of the food ingredients and ensuring the fineness of the crushing of the food ingredients.

[0087] According to an embodiment of the present invention, refer to Figure 13 , in the embodiment of the present invention, the first stationary grinding disc 100 includes two parts of structures, namely a bottom plate 150 located at the bottom and a side plate 152 arranged on the circumferential side of the bottom plate 150. As described above, since the cross-sectional shape of the first stationary grinding disc 100 is generally circular, correspondingly, in the embodiment of the present invention, the bottom plate 150 is circular. Along the circumferential direction of the bottom plate 150, a side plate 152 is arranged at the edge of the bottom plate 150, and correspondingly, the side plate 152 is arc-shaped.

[0088] The above-mentioned second grinding part 106 is formed on the side wall of the side plate 152 facing the bottom plate 150. Please continue to refer to Figure 13 , in the embodiment of the present invention, the second grinding part 106 extends along the height direction of the side plate 152 and is spaced at intervals along the circumferential direction of the inner side wall of the side plate 152.

[0089] A second opening 154 for throwing out the food ingredients is also formed on the side plate 152. As described above, when the moving grinding disc group 102 rotates, the food ingredients will be thrown out, and the thrown-out food ingredients can enter the cup body 10 through the second opening 154 on the side plate 152.

[0090] In an embodiment of the present invention, the first stationary grinding disc 100 can be made of a material with relatively high strength. For example, the first stationary grinding disc 100 can be made of stainless steel material. Thus, by using a material with relatively high strength to make the first stationary grinding disc 100, the structural strength of the first stationary grinding disc 100 can be effectively ensured, the deformation of the second grinding part 106 can be effectively prevented, and the service life of the first stationary grinding disc 100 is guaranteed.

[0091] The side plate 152 and the chassis 150 can be made by an integral molding method, which can further improve the structural strength of the side plate 152 and the chassis 150.

[0092] With reference to Figure 1 and Figure 5 , according to an embodiment of the present invention, the grinding assembly further includes a base (not shown in the figure) and a cutter disc 158.

[0093] The base is used to support components such as the crushing device and the cup body 10.

[0094] An accommodation space is formed in the base, and a driving member 156 is installed in the accommodation space. The driving member 156 can be an element such as a motor or a motor that can achieve power output.

[0095] The cutter disc 158 is seated in the base. In an embodiment of the present invention, the shape of the cutter disc 158 is similar to a bowl shape. A first mounting hole 162 is formed at the bottom of the cutter disc 158, and the first mounting hole 162 is a through hole. There is a certain spatial structure in the cutter disc 158, and this spatial structure is used to install the crushing device. It can be understood that the moving grinding disc group 102 and the first stationary grinding disc 100 are installed in the spatial structure in the cutter disc 158.

[0096] The moving grinding disc group 102 in the crushing device and the driving shaft 160 of the driving member 156 can be connected through a connection structure, and the connection structure can be installed in the first mounting hole 162 on the cutter disc 158.

[0097] The connection structure provided by the embodiment of the present invention will be specifically described below:

[0098] In an embodiment of the present invention, the connection structure mainly includes three parts, namely a buckle disc 164, a coupling 168, and a sealing ring 170.

[0099] The buckle disc 164 is buckled on the cutter disc 158. A second connecting shaft 166 is passed through the buckle disc 164. The buckle disc 164 is stationary, and the second connecting shaft 166 can rotate relative to the buckle disc 164.

[0100] The second connecting shaft 166 can use a hexagonal shaft. The second connecting shaft 166 is passed through the first mounting hole 162. The first end of the second connecting shaft 166 is connected to the moving grinding disc group 102, that is, asFigure 5 The top end of the second connecting shaft 166 shown is connected to the moving grinding disc group 102 to drive the moving grinding disc group 102 to rotate.

[0101] In addition, in order to fix the second connecting shaft 166 and prevent the second connecting shaft 166 from disengaging from the first mounting hole 162, a threaded section is provided on the section of the second connecting shaft 166 passing through the first mounting hole 162, and a fastening member 172 such as a nut is threadedly connected to the threaded section. In this way, by the threaded connection between the nut and the threaded section, the second connecting shaft 166 can be locked on the cutter disc 158.

[0102] The coupling 168 is used to connect the second end of the second connecting shaft 166 and the first end of the drive shaft 160. That is, the second end of the second connecting shaft 166 refers to the bottom end of the second connecting shaft 166 as shown in Figure 5 and the first end of the drive shaft 160 refers to the top end of the drive shaft 160 as shown in Figure 1 .

[0103] The sealing ring 170 can be made of materials such as rubber and silica gel. The sealing ring 170 mainly has the following two functions:

[0104] The first function of the sealing ring 170 is that it can isolate the second connecting shaft 166 from the hole side wall of the first mounting hole 162, thereby preventing the second connecting shaft 166 from colliding with the hole side wall of the first mounting hole 162 when rotating, and further reducing the noise when the second connecting shaft 166 rotates;

[0105] The second function of the sealing ring 170 is to prevent food ingredients from entering the driving member 156 on the base through the first mounting hole 162, avoiding the driving member 156 being affected by external impurities.

[0106] In addition, as shown in Figure 5 , a sealing flange is provided at the top of the sealing ring 170, and the sealing flange can play the sealing role described above for the butting disc 164 and the bottom of the cutter disc 158.

[0107] In order to prevent the sealing ring 170 from rotating synchronously with the second connecting shaft 166, a clamping protrusion is provided on the hole side wall of the first mounting hole 162. Correspondingly, a clamping groove that is clamped and adapted to the clamping protrusion is provided on the side wall of the sealing ring 170, thereby effectively restricting the synchronous rotation of the sealing ring 170 and the second connecting shaft 166, and further ensuring the vibration reduction and sealing effects of the sealing ring 170.

[0108] Please refer to Figure 1 , Figure 2 and Figure 14, as described above, the moving grinding disc group 102 and the first stationary grinding disc 100 are installed in the spatial structure in the cutter head 158. Thus, according to an embodiment of the present invention, a second mounting hole 174 penetrating through the chassis 150 is formed in the chassis 150.

[0109] After the fastening disc 164 is locked on the cutter head 158 through the second connecting shaft 166, a part of the second connecting shaft 166 passes through the second mounting hole 174, and the connection between the fastening disc 164 and the second mounting hole 174 is realized through the second clamping structure. Thus, the purpose of locking the fastening disc 164 and the cutter head 158 on the chassis 150 can be achieved.

[0110] In the embodiment of the present invention, the second clamping structure can be formed in at least the following several ways:

[0111] Forming method one:

[0112] With reference to Figure 5 and Figure 13 , in this forming method, the second clamping structure includes a second buckle 176 and a second clamping groove 178 that are clamped and adapted to each other. The second buckle 176 is arranged on the fastening disc 164, and the second clamping groove 178 is arranged on the hole side wall of the second mounting hole 174.

[0113] The second clamping grooves 178 are arranged at intervals along the hole side wall of the second mounting hole 174, and the second buckles 176 are arranged at intervals along the edge of the side wall of the fastening disc 164. When the fastening disc 164 is installed on the cutter head 158 and the second connecting shaft 166 passes through the second mounting hole 174 on the chassis 150, by rotating the fastening disc 164 to a certain extent, the second buckles 176 on the fastening disc 164 can be clamped into the second clamping grooves 178 on the hole side wall of the second mounting hole 174, thereby locking the fastening disc 164 and the cutter head 158 on the chassis 150.

[0114] Forming method two:

[0115] In this forming method, the second clamping structure includes a second buckle 176 and a second clamping groove 178 that are clamped and adapted to each other. The second buckle 176 is arranged on the hole side wall of the second mounting hole 174, and the second clamping groove 178 is arranged on the fastening disc 164.

[0116] The second buckles 176 are arranged at intervals along the hole side wall of the second mounting hole 174, and the second clamping grooves 178 are arranged at intervals along the edge of the side wall of the fastening disc 164. When the fastening disc 164 is installed on the cutter head 158 and the second connecting shaft 166 passes through the second mounting hole 174 on the chassis 150, by rotating the fastening disc 164 to a certain extent, the second clamping grooves 178 on the fastening disc 164 can be clamped with the second buckles 176 on the hole side wall of the second mounting hole 174, thereby locking the fastening disc 164 and the cutter head 158 on the chassis 150.

[0117] Forming method three:

[0118] In this forming method, the second clamping structure includes a clamping adapter ring and a clamping groove. The clamping ring is arranged on the buckle plate 164, and the clamping groove is arranged on the hole side wall of the second mounting hole 174.

[0119] The clamping groove is arranged along the hole side wall of the second mounting hole 174 on the hole side wall of the second mounting hole 174, and the clamping ring is arranged along the edge of the side wall of the buckle plate 164. When the buckle plate 164 is installed on the cutter disc 158 and the second connecting shaft 166 passes through the second mounting hole 174 on the chassis 150, the clamping ring on the buckle plate 164 can be clamped in the clamping groove on the hole side wall of the second mounting hole 174, so that the buckle plate 164 and the cutter disc 158 can be locked on the chassis 150.

[0120] Forming method four:

[0121] In this forming method, the second clamping structure includes a clamping adapter ring and a clamping groove. The clamping ring is arranged on the buckle plate 164, and the clamping groove is arranged on the hole side wall of the second mounting hole 174.

[0122] The clamping ring is arranged along the hole side wall of the second mounting hole 174 on the hole side wall of the second mounting hole 174, and the clamping groove is arranged along the edge of the side wall of the buckle plate 164. When the buckle plate 164 is installed on the cutter disc 158 and the second connecting shaft 166 passes through the second mounting hole 174 on the chassis 150, the clamping groove on the buckle plate 164 can be clamped with the clamping ring on the hole side wall of the second mounting hole 174, so that the buckle plate 164 and the cutter disc 158 can be locked on the chassis 150.

[0123] Of course, the second clamping structure can also be in other forms, as long as it can achieve the purpose of locking the buckle plate 164, the cutter disc 158 on the chassis 150.

[0124] In this way, by setting the buckle plate 164, the cutter disc 158 and the first static grinding disc 100 in a mutually clamped form, the buckle plate 164, the cutter disc 158 and the first static grinding disc 100 can be installed as a whole. When disassembling, the buckle plate 164, the cutter disc 158 and the first static grinding disc 100 can also be disassembled separately, ensuring the convenience of user cleaning.

[0125] According to an embodiment of the present invention, see Figures 10 to 12 , in the embodiment of the present invention, the moving grinding disc group 102 mainly includes two parts of structures, namely the first moving grinding disc 108 and the second moving grinding disc 116. Among them, the second moving grinding disc 116 is inserted into the first moving grinding disc 108, that is to say, it can be understood that the first moving grinding disc 108 is provided with an insertion space for inserting the second moving grinding disc 116.

[0126] As described above, since the cross-sectional shape of the first static grinding disc 100 is approximately circular, for the convenience of installation, the cross-sectional shapes of the first dynamic grinding disc 108 and the second dynamic grinding disc 116 are also circular. Similarly, the first dynamic grinding disc 108 and the second dynamic grinding disc 116 can also be made of materials with higher strength. For example, stainless steel materials can be used to make the first dynamic grinding disc 108 and the second dynamic grinding disc 116.

[0127] It should be noted that after the second dynamic grinding disc 116 is inserted into the first dynamic grinding disc 108, the second dynamic grinding disc 116 and the first dynamic grinding disc 108 can rotate synchronously. Among them, a positioning structure can be adopted between the second dynamic grinding disc 116 and the first dynamic grinding disc 108 to achieve the above purpose. For example, the positioning structure can be a cooperation mode of a positioning hole and a positioning shaft. Specifically, a hexagonal positioning hole can be provided at the middle position of the second dynamic grinding disc 116 facing the first dynamic grinding disc 108, and a hexagonal positioning shaft can be provided at the middle position of the first dynamic grinding disc 108 facing the second dynamic grinding disc 116. A through hole adapted to the shape of the hexagonal positioning hole is provided in the middle of the positioning shaft. After the second dynamic grinding disc 116 is inserted into the first dynamic grinding disc 108, the positioning shaft on the first dynamic grinding disc 108 can be inserted into the positioning hole on the second dynamic grinding disc 116, and thus the synchronous rotation of the two can be achieved.

[0128] In addition, the second connecting shaft 166 (i.e., the hexagonal shaft) described above can also pass through the through holes on the first dynamic grinding disc 108 and the hexagonal positioning holes on the second dynamic grinding disc 116 respectively. Thus, when the driving member 156 acts, the driving shaft 160 rotates, and the rotation of the driving shaft 160 can drive the coupling 168 to act. The coupling 168 can achieve the synchronous rotation of the second connecting shaft 166 and the driving shaft 160. At the same time, through the cooperation of the second connecting shaft 166 with the through holes on the first dynamic grinding disc 108 and the hexagonal positioning holes on the second dynamic grinding disc 116, the purpose of driving the first dynamic grinding disc 108 and the second dynamic grinding disc 116 to rotate can be achieved.

[0129] Of course, the positioning structure can also be a cooperation mode of a positioning groove and a positioning protrusion. Specifically, a plurality of positioning grooves can be provided on the surface of the second dynamic grinding disc 116 facing the first dynamic grinding disc 108, and a plurality of positioning protrusions corresponding to the positioning grooves can be provided on the surface of the first dynamic grinding disc 108 facing the second dynamic grinding disc 116. After the second dynamic grinding disc 116 is inserted into the first dynamic grinding disc 108, the positioning protrusions can be clamped into the corresponding positioning grooves, and thus the synchronous rotation of the two can be achieved.

[0130] Of course, the positioning structure between the first dynamic grinding disc 108 and the second dynamic grinding disc 116 can also be other structures that can achieve the positioning function, and will not be enumerated one by one here.

[0131] SeeFigure 11 and Figure 12 Along the circumferential direction of the first rotating grinding disc 108, a plurality of first main grinding teeth 110 and a plurality of first secondary grinding teeth 112 are provided at the edge of the first rotating grinding disc 108. Among them, the plurality of first main grinding teeth 110 are spaced apart and arranged at a position close to the edge on the first rotating grinding disc 108, and the plurality of first secondary grinding teeth 112 are spaced apart and arranged at a relatively inner position on the first rotating grinding disc 108. That is, the first secondary grinding teeth 112 are arranged on the first rotating grinding disc 108 and are located within the annular circle formed by the surrounding of the first main grinding teeth 110. That is, the first secondary grinding teeth 112 are located within the inner circle of the first main grinding teeth 110. The inner circle mentioned here refers to the side of the first main grinding teeth 110 facing the rotation center of the first rotating grinding disc 108.

[0132] The distance between two adjacent first main grinding teeth 110 is equal. Similarly, the distance between two adjacent first secondary grinding teeth 112 is equal. The number of the first main grinding teeth 110 and the number of the first secondary grinding teeth 112 can be flexibly set according to specific situations. It should be noted that the number of the first main grinding teeth 110 corresponds to the number of the first secondary grinding teeth 112 one by one.

[0133] On the outer side wall of the first main grinding teeth 110, a first crushing groove 114 extending along the height direction of the first main grinding teeth 110 is formed. The depth of the first crushing groove 114 should not be set too deep to avoid food ingredients getting stuck in it.

[0134] See Figure 10 Along the circumferential direction of the second rotating grinding disc 116, a plurality of second main grinding teeth 118 and a plurality of second secondary grinding teeth 120 are provided at the edge of the second rotating grinding disc 116. Among them, the plurality of second main grinding teeth 118 are spaced apart and arranged at a position close to the edge on the second rotating grinding disc 116, and the plurality of second secondary grinding teeth 120 are spaced apart and arranged at a relatively inner position on the second rotating grinding disc 116. That is, the second secondary grinding teeth 120 are arranged on the second rotating grinding disc 116 and are located within the annular circle formed by the surrounding of the second main grinding teeth 118. That is, the second secondary grinding teeth 120 are located within the inner circle of the second main grinding teeth 118. The inner circle mentioned here refers to the side of the second main grinding teeth 118 facing the rotation center of the second rotating grinding disc 116.

[0135] The distance between two adjacent second main grinding teeth 118 is equal. Similarly, the distance between two adjacent second secondary grinding teeth 120 is equal. The number of the second main grinding teeth 118 and the number of the second secondary grinding teeth 120 can be flexibly set according to specific situations. It should be noted that the number of the second main grinding teeth 118 corresponds to the number of the second secondary grinding teeth 120 one by one.

[0136] On the outer side wall of the second main grinding teeth 118, a second crushing groove 122 extending along the height direction of the second main grinding teeth 118 is formed. The depth of the second crushing groove 122 should not be set too deep to avoid food ingredients getting stuck in it.

[0137] When the second moving grinding disc 116 is inserted into the first moving grinding disc 108, align the second main grinding teeth 118 on the second moving grinding disc 116 with the gap between two adjacent first main grinding teeth 110 on the first moving grinding disc 108, and align the second secondary grinding teeth 120 on the second moving grinding disc 116 with the gap between two adjacent first secondary grinding teeth 112 on the first moving grinding disc 108. In this way, the insertion connection between the second moving grinding disc 116 and the first moving grinding disc 108 can be achieved.

[0138] In this way, the second main grinding teeth 118 on the second moving grinding disc 116 and the first main grinding teeth 110 on the first moving grinding disc 108 are aligned with each other to form a main grinding tooth ring 124; correspondingly, the second secondary grinding teeth 120 on the second moving grinding disc 116 and the first secondary grinding teeth 112 on the first moving grinding disc 108 are aligned with each other to form a secondary grinding tooth ring 126.

[0139] It should be noted that the main grinding tooth ring 124 and the secondary grinding tooth ring 126 mentioned here are not complete and continuous tooth rings. There is a certain gap between two adjacent first main grinding teeth 110 and the second main grinding teeth 118 in the main grinding tooth ring 124. Similarly, there is also a certain gap between two adjacent first secondary grinding teeth 112 and the second secondary grinding teeth 120 in the secondary grinding tooth ring 126.

[0140] Of course, in some other embodiments, the second main grinding teeth 118 on the second moving grinding disc 116 and the first main grinding teeth 110 on the first moving grinding disc 108 can also be arranged in an alternating form. Similarly, the second secondary grinding teeth 120 on the second moving grinding disc 116 and the first secondary grinding teeth 112 on the first moving grinding disc 108 can also be arranged in an alternating form.

[0141] See Figure 16 , in the embodiment of the present invention, the value range of the distance W2 between the first main grinding teeth 110 and the second main grinding teeth 118 is 0.3 mm to 3 mm. The distance between the first main grinding teeth 110 and the second main grinding teeth 118 is mainly used for filtering food materials, and the cavitation effect is secondary; the value range of the distance W1 between the first secondary grinding teeth 112 and the second secondary grinding teeth 120 is 2 mm to 5 mm; the distance between the first secondary grinding teeth 112 and the second secondary grinding teeth 120 is mainly used for generating the cavitation effect, and filtering food materials is secondary.

[0142] In addition, after the second moving grinding disc 116 is inserted into the first moving grinding disc 108, the main grinding tooth ring 124 and the secondary grinding tooth ring 126 are also arranged at intervals, that is, there is a first gap between them. At the same time, there is also a gap between the outer side wall of the main grinding tooth ring 124 and the inner side wall of the side plate 152 in the first static grinding disc 100.

[0143] After the second moving grinding disc 116 is inserted into the first moving grinding disc 108, the first grinding groove 114 on the outer sidewall of the first main grinding tooth 110 and the second grinding groove 122 on the outer sidewall of the second main grinding tooth 118 together form the first grinding part 104. Among them, the width and height of the first grinding groove 114 can be set to be the same as those of the second grinding groove 122, so as to ensure that the first grinding part 104 formed after the combination of the two cooperates with the second grinding part 106 in the first static grinding disc 100, and the crushed food particles are more uniform.

[0144] It should be noted that in the embodiment of the present invention, the first grinding part 104 is jointly composed of the first grinding groove 114 and the second grinding groove 122. In some other embodiments, the first grinding part 104 can also be composed of protrusions provided on the outer sidewall of the first main grinding tooth 110 and on the outer sidewall of the second main grinding tooth 118. Correspondingly, the second grinding part 106 can also be set in a protruding structure.

[0145] In this way, when the food is put into the cup body 10, the food can enter the first moving grinding disc 108 and the second moving grinding disc 116. As the first moving grinding disc 108 and the second moving grinding disc 116 rotate, the food can enter the first gap described above through the gap between the first secondary grinding tooth 112 and the second secondary grinding tooth 120 in the secondary grinding tooth ring 126. As the first moving grinding disc 108 and the second moving grinding disc 116 continue to rotate, the food in the first gap is thrown out through the gap between the first main grinding tooth 110 and the second main grinding tooth 118 in the main grinding tooth ring 124 to the gap between the outer sidewall of the main grinding tooth ring 124 and the inner sidewall of the first static grinding disc 100. The food entering this gap can be thrown out of the moving grinding disc group 102 and the first static grinding disc 100 under the action of the centrifugal force provided when the moving grinding disc group 102 rotates after being crushed and extruded by the first grinding part 104 and the second grinding part 106. The thrown-out food can enter the cup body 10 through the fifth gap.

[0146] When the food is thrown out into the cup body 10, due to a certain negative pressure formed inside the first moving grinding disc 108 and the second moving grinding disc 116, the food in the cup body 10 can be sucked into the first moving grinding disc 108 and the second moving grinding disc 116 again, and then the above steps are repeated, so as to form a cyclic crushing and grinding of the food. Thus, the complete crushing of the food can be realized, ensuring the fineness of the food crushing.

[0147] According to an embodiment of the present invention, refer to Figure 8 and Figure 9, the crushing device provided by the embodiment of the present invention further includes a second static grinding disc 128. The second static grinding disc 128 is used to be clamped with the first static grinding disc 100 to form a certain grinding space between the first static grinding disc 100 and the second static grinding disc 128, and this grinding space is used to install the first dynamic grinding disc 108 and the second dynamic grinding disc 116.

[0148] The shape of the cross-section of the second static grinding disc 128 is the same as that of the cross-section of the first static grinding disc 100, that is, the shape of the cross-section of the second static grinding disc 128 is also circular. The second static grinding disc 128 can be made of a material with relatively high strength, such as stainless steel. Thus, the second static grinding disc 128 made of this material can effectively ensure the structural strength of the second static grinding disc 128.

[0149] In the embodiment of the present invention, the second static grinding disc 128 and the first static grinding disc 100 are connected through a first clamping structure.

[0150] In the embodiment of the present invention, the first clamping structure can be formed in at least the following several ways:

[0151] Forming method one:

[0152] The first clamping structure includes a first buckle 144 and a first clamping groove 146 that are clamped and adapted. The first buckle 144 is arranged on the first static grinding disc 100, and the first clamping groove 146 is arranged on the second static grinding disc 128.

[0153] Combined with reference to Figures 7 to 9 and Figure 13 , in this forming method, the first buckle 144 is arranged on the outer side wall of the side plate 152 of the first static grinding disc 100, and the first clamping groove 146 is formed on the surface of the second static grinding disc 128 facing the first static grinding disc 100. Among them, the first clamping groove 146 can be formed by two relatively arranged L-shaped plates. When the first buckle 144 is clamped between the two relatively arranged L-shaped plates, by rotating the second static grinding disc 128, the purpose of clamping the first buckle 144 in the first clamping groove 146 can be achieved. Thus, the second static grinding disc 128 can be clamped to the first static grinding disc 100.

[0154] Forming method two:

[0155] The first clamping structure includes a first buckle 144 and a first clamping groove 146 that are clamped and adapted. The first buckle 144 is arranged on the first static grinding disc 100, and the first clamping groove 146 is arranged on the second static grinding disc 128.

[0156] In this forming method, the first card slot 146 is arranged on the outer side wall of the side plate 152 of the first static grinding disc 100, and the first snap 144 is formed on the surface of the second static grinding disc 128 on the side facing the first static grinding disc 100. Among them, the first card slot 146 can be formed by two oppositely arranged L-shaped plates. After the first snap 144 is snapped between the two oppositely arranged L-shaped plates, by rotating the first static grinding disc 100, the purpose of snapping the first snap 144 into the first card slot 146 can be achieved. Thus, the second static grinding disc 128 can be snapped onto the first static grinding disc 100.

[0157] Forming method three:

[0158] The first snap connection structure includes a snap projection and a snap hole that are snap-fitted. The snap projection is arranged on the first static grinding disc 100, and the snap hole is arranged on the second static grinding disc 128.

[0159] In this forming method, the snap hole is arranged on the outer side wall of the side plate 152 of the first static grinding disc 100, and a columnar structural member is arranged on the second static grinding disc 128. The snap projection is formed on the columnar structural member on the second static grinding disc 128. When the second static grinding disc 128 is aligned with the first static grinding disc 100, the snap projection on the columnar structural member can be snapped into the snap hole on the first static grinding disc 100. Thus, the second static grinding disc 128 can be snapped onto the first static grinding disc 100.

[0160] Forming method four:

[0161] The first snap connection structure includes a snap projection and a snap hole that are snap-fitted. The snap hole is arranged on the first static grinding disc 100, and the snap projection is arranged on the second static grinding disc 128.

[0162] In this forming method, the snap projection is arranged on the outer side wall of the side plate 152 of the first static grinding disc 100, and the snap hole is formed on the surface of the second static grinding disc 128 on the side facing the first static grinding disc 100. When the second static grinding disc 128 is aligned with the first static grinding disc 100, the snap hole on the second static grinding disc 128 can be snapped into the snap projection on the first static grinding disc 100. Thus, the second static grinding disc 128 can be snapped onto the first static grinding disc 100.

[0163] Of course, the first snap connection structure can also be other structures that can achieve the snap connection function, and they will not be enumerated one by one here.

[0164] In this way, by arranging the first static grinding disc 100 and the second static grinding disc 128 in a snap-connected form, the first static grinding disc 100 and the second static grinding disc 128 can be used as a whole for crushing and grinding. When disassembling, the first static grinding disc 100 and the second static grinding disc 128 can also be removed separately, ensuring the convenience of user cleaning.

[0165] SeeFigures 6 to 8 To facilitate the disassembly by the user, according to an embodiment of the present invention, a handle 148 is further provided on the side of the second static grinding disc 128 facing away from the first static grinding disc 100, that is, on the side of the second static grinding disc 128 away from the grinding space formed with the first static grinding disc 100.

[0166] The handle 148 can be folded and retracted or erected vertically. After the handle 148 is folded and retracted, the user can use the grinding assembly to crush the food ingredients. After the handle 148 is erected vertically, the user can hold the handle 148 to lift the second static grinding disc 128, the first static grinding disc 100, and the first dynamic grinding disc 108 and the second dynamic grinding disc 116 installed in the grinding space.

[0167] Please refer to Figure 10 and Figure 12 According to an embodiment of the present invention, a first crushing knife 130 is provided between the second secondary grinding teeth 120 on the second dynamic grinding disc 116 for preliminarily crushing the food ingredients entering the second dynamic grinding disc 116.

[0168] After the second dynamic grinding disc 116 is inserted into the first dynamic grinding disc 108, the first crushing knife 130 can act synchronously with the rotation of the first dynamic grinding disc 108 and the second dynamic grinding disc 116. That is, when the food ingredients enter the dynamic grinding disc group 102, the food ingredients are first preliminarily crushed by the first crushing knife 130, and then enter the first dynamic grinding disc 108 and the second dynamic grinding disc 116 to achieve further crushing and grinding of the food ingredients.

[0169] Please refer to Figure 8 A plurality of first openings 132 are formed on the second static grinding disc 128, wherein the first openings 132 communicate with the cup 10 and the grinding space formed by the first static grinding disc 100 and the second static grinding disc 128 described above. When the food ingredients are put into the cup 10, the food ingredients can enter the grinding space formed by the first static grinding disc 100 and the second static grinding disc 128 through the first openings 132, that is, the food ingredients can enter the first dynamic grinding disc 108 and the second dynamic grinding disc 116 through the first openings 132. Along the radial direction of the first openings 132, the projection of the outer edge of the first openings 132 is located within the annular circle formed by the outer diameter of the secondary grinding tooth ring 126. In this way, when the food ingredients are put into the cup 10, the food ingredients can completely fall into the first dynamic grinding disc 108 and the second dynamic grinding disc 116 through the first openings 132, and then the food ingredients can be crushed and ground through the grinding of the first dynamic grinding disc 108 and the second dynamic grinding disc 116.

[0170] To achieve the preliminary crushing of the food ingredients placed in the cup 10, a first connecting shaft 134 is installed at the middle position of the second static grinding disc 128, wherein the first connecting shaft 134 can rotate relative to the second static grinding disc 128.

[0171] At one end of the first connecting shaft 134 facing away from the first static grinding disc 100, that is, at the top end of the first connecting shaft 134 as shown in Figure 8 Figure, a second crushing knife 136 is installed. At one end of the first connecting shaft 134 facing the first static grinding disc 100, that is, at the bottom end of the first connecting shaft 134 as shown in Figure 12 Figure, it is connected to the first crushing knife 130 in the second moving grinding disc 116. Thus, when the first crushing knife 130 rotates driven by the first moving grinding disc 108 and the second moving grinding disc 116, the second crushing knife 136 can rotate synchronously with the first crushing knife 130.

[0172] Specifically, in the embodiment of the present invention, as described above, the second connecting shaft 166 (that is, the hexagonal shaft) passes through the through holes on the first moving grinding disc 108 and the hexagonal positioning holes on the second moving grinding disc 116 respectively. Correspondingly, an opening adapted to the shape of the second connecting shaft 166 can also be provided at the end of the first connecting shaft 134 facing the first static grinding disc 100, and then the second connecting shaft 166 is inserted into the opening at the end position of the first connecting shaft 134. Thus, when the driving member 156 acts, the driving shaft 160 acts, and the driving shaft 160 drives the second connecting shaft 166 to rotate synchronously through the coupling 168. The second connecting shaft 166 drives the first moving grinding disc 108, the second moving grinding disc 116, the first crushing knife 130, and the first connecting shaft 134 to rotate synchronously. Correspondingly, the second crushing knife 136 on the first connecting shaft 134 also rotates synchronously.

[0173] In this way, when the user puts the food ingredients into the cup body 10, the food ingredients are first preliminarily crushed by the second crushing knife 136, enter the grinding space through the first opening 132 on the second static grinding disc 128, and the first crushing knife 130 further crushes the food ingredients entering the grinding space. Then the food ingredients enter the first moving grinding disc 108 and the second moving grinding disc 116, and are crushed and ground multiple times in the way of crushing, grinding, and circulating as described above.

[0174] According to an embodiment of the present invention, referring to Figure 8 and Figure 9 , since the cross-sectional shape of the second static grinding disc 128 is also circular, thus, along the circumferential direction of the second static grinding disc 128, a plurality of third grinding teeth 138 are arranged at intervals on the edge of the second static grinding disc 128. In the embodiment of the present invention, the distance between two adjacent third grinding teeth 138 is equal.

[0175] It should be noted that when the second static grinding disc 128 is clamped to the first static grinding disc 100, the third grinding teeth 138 on the second static grinding disc 128 are located in the first gap formed between the main grinding tooth ring 124 and the sub-grinding tooth ring 126.

[0176] After the second static grinding disc 128 is clamped in the first static grinding disc 100, it also means that at this time, the third grinding teeth 138 are located in the first gap formed between the main grinding tooth ring 124 and the secondary grinding tooth ring 126. At this time, there is a space between the outer side wall of the third grinding teeth 138 and the inner side wall of the main grinding tooth ring 124, and a second gap is formed therebetween; there is a space between the inner side wall of the third grinding teeth 138 and the outer side wall of the secondary grinding tooth ring 126, and a third gap is formed therebetween; there is a sixth gap between the outer side wall of the main grinding tooth ring 124 and the inner side wall of the first static grinding disc 100.

[0177] In this way, by providing the third grinding teeth 138, after the second static grinding disc 128 is clamped in the first static grinding disc 100, the food ingredients can enter the second gap between the outer side wall of the third grinding teeth 138 and the inner side wall of the main grinding tooth ring 124 and the third gap W3 between the inner side wall of the third grinding teeth 138 and the outer side wall of the secondary grinding tooth ring 126. Furthermore, through the action of the outer side wall of the third grinding teeth 138 and the inner side wall of the main grinding tooth ring 124, the inner side wall of the third grinding teeth 138 and the outer side wall of the secondary grinding tooth ring 126, and the first grinding part 104 on the main grinding tooth ring 124 and the second grinding part 106 on the first static grinding disc 100, a comprehensive effect such as strong and reciprocating hydraulic shear, friction, centrifugal extrusion, liquid flow collision, and cavitation effect of instantaneous bubble collapse on the food ingredients is realized, and the crushing of the food ingredients is achieved.

[0178] In the embodiment of the present invention, the main function of the third gap is for shear crushing. At the same time, considering the problems of processing accuracy and assembly accuracy, the value range of the third gap is 0.3 mm to 1 mm.

[0179] Please refer to Figure 9 , according to an embodiment of the present invention, a cutting-in tooth 140 is further provided inside the third grinding teeth 138 on the second static grinding disc 128. The purpose of providing the cutting-in tooth 140 is to introduce the food ingredients in the secondary grinding tooth ring 126 into the second gap between the outer side wall of the third grinding teeth 138 and the inner side wall of the main grinding tooth ring 124 and / or the third gap between the inner side wall of the third grinding teeth 138 and the outer side wall of the secondary grinding tooth ring 126.

[0180] When the second static grinding disc 128 is clamped in the first static grinding disc 100, there is a space between the cutting-in tooth 140 and the inner side wall of the secondary grinding tooth ring 126, and a fourth gap is formed therebetween.

[0181] In the embodiment of the present invention, the sixth gap is smaller than the second gap, and the second gap is smaller than the third gap; and / or the sixth gap is smaller than the second gap, the second gap is smaller than or equal to the third gap, and the third gap is smaller than or equal to the fourth gap.

[0182] That is, the gap between the outer wall of the main grinding gear ring 124 and the inner wall of the first stationary grinding disc 100 is smaller than the gap between the outer wall of the third grinding tooth 138 and the inner wall of the main grinding gear ring 124, and the gap between the outer wall of the third grinding tooth 138 and the inner wall of the main grinding gear ring 124 is smaller than the gap between the inner wall of the third grinding tooth 138 and the outer wall of the auxiliary grinding gear ring 126.

[0183] On this basis, the gap between the inner wall of the third grinding tooth 138 and the outer wall of the auxiliary grinding gear ring 126 is smaller than the gap between the cutting-in tooth 140 and the inner wall of the auxiliary grinding gear ring 126.

[0184] It can be understood that when the first moving grinding disc 108 and the second moving grinding disc 116 rotate relative to the first stationary grinding disc 100 and the second stationary grinding disc 128, the food materials can be swirled into the second gap between the outer wall of the third grinding tooth 138 and the inner wall of the main grinding gear ring 124 and / or the third gap between the inner wall of the third grinding tooth 138 and the outer wall of the auxiliary grinding gear ring 126 under the guidance of the cutting-in tooth 140, and then the food materials are crushed through the crushing and grinding between the third grinding tooth 138 and the main grinding gear ring 124, and between the third grinding tooth 138 and the auxiliary grinding gear ring 126.

[0185] See Figure 16 , according to an embodiment of the present invention, a guiding surface 142 is provided on the cutting-in tooth 140. The function of the guiding surface 142 is to guide the food materials so as to introduce the food materials in the second stationary grinding disc 128 into the second gap and / or the third gap. The guiding surface 142 can be an inclined plane or an inclined curved surface. In the embodiment of the present invention, the guiding surface 142 is an inclined plane.

[0186] See Figure 16 , there is an included angle γ between the guiding surface 142 and the circumferential tangent plane of the moving grinding disc group 102 at the corresponding position of the cutting-in tooth 140. Here, this included angle is defined as the cutting-in angle. The size of the cutting-in angle determines the pressure when the food materials are squeezed in. The larger the angle of the cutting-in angle, the greater the squeezing pressure. The greater the squeezing pressure, the greater the resistance generated when the auxiliary grinding gear ring 126 rotates. Therefore, in the embodiment of the present invention, the value range of this cutting-in angle is from 10 degrees to 50 degrees.

[0187] According to an embodiment of the present invention, the gap between two adjacent cutting teeth 140 is greater than the gap between two adjacent third grinding teeth 138; and / or the number of cutting teeth 140 is less than the number of third grinding teeth 138. That is, the cutting teeth 140 can introduce the food ingredients in the secondary grinding tooth ring 126 into the second gap between the outer side wall of the third grinding teeth 138 and the inner side wall of the main grinding tooth ring 124 and / or the third gap between the inner side wall of the third grinding teeth 138 and the outer side wall of the secondary grinding tooth ring 126; through the gap between two adjacent third grinding teeth 138, after the second stationary grinding disc 128 is clamped to the first stationary grinding disc 100, the food ingredients can enter the second gap between the outer side wall of the third grinding teeth 138 and the inner side wall of the main grinding tooth ring 124 and the third gap W3 between the inner side wall of the third grinding teeth 138 and the outer side wall of the secondary grinding tooth ring 126.

[0188] In addition, the distance between the first main grinding tooth 110 and the second main grinding tooth 118 is less than the gap between the first secondary grinding tooth 112 and the second secondary grinding tooth 120, and the gap between the first secondary grinding tooth 112 and the second secondary grinding tooth 120 is less than the gap between two adjacent cutting teeth 140.

[0189] It can be understood that the food ingredients preliminarily crushed by the second crushing knife 136 enter the grinding space. At this time, the particle size of the food ingredients is relatively large. At this time, the cutting teeth 140 introduce the food ingredients in the secondary grinding tooth ring 126 into the third gap between the inner side wall of the third grinding teeth 138 and the outer side wall of the secondary grinding tooth ring 126 through the gap between the first secondary grinding tooth 112 and the second secondary grinding tooth 120. At this time, the particle size of the food ingredients is relatively finer; then the food ingredients in the third gap pass through the gap between the third grinding teeth 138 and enter the second gap between the outer side wall of the third grinding teeth 138 and the inner side wall of the main grinding tooth ring 124. At this time, the particle size of the food ingredients is further refined.

[0190] The following is a simple description of the use process of the grinding assembly provided by the embodiment of the present invention:

[0191] Combined with Figures 1 to 17 , first, put the food ingredients into the cup body 10;

[0192] Secondly, the user can turn on the driving member 156 to make the driving shaft 160 act. The driving shaft 160 can drive the coupling 168 to act. The coupling 168 can realize the synchronous rotation of the second connecting shaft 166 and the driving shaft 160. At the same time, through the cooperation of the second connecting shaft 166 with the through holes on the first moving grinding disc 108 and the hexagonal positioning holes on the second moving grinding disc 116, the purpose of driving the first moving grinding disc 108 and the second moving grinding disc 116 to rotate can be achieved;

[0193] Again, the ingredients in the cup body 10 can be preliminarily crushed by the second crushing knives 136 on the second static grinding disc 128, and then enter the grinding space through the first opening 132;

[0194] Again, the ingredients that enter the grinding space are secondarily crushed by the first crushing knives 130, and then finely crushed by the crushing and extrusion of the moving grinding disc group 102 and the first static grinding disc 100. When the moving grinding disc group 102 rotates, the ingredients in the grinding space are affected by the centrifugal force and are thrown out through the second opening 154 on the first static grinding disc 100. The thrown-out ingredients can enter the cup body 10 through the fifth gap;

[0195] Again, after the ingredients are thrown out into the cup body 10, due to the continuous high-speed rotation of the moving grinding disc group 102, a certain negative pressure will be formed inside the moving grinding disc group 102. The ingredients in the cup body 10 can be sucked into the grinding space again through the first opening 132 on the second static grinding disc 128, and after being crushed by the first crushing knives 130 and secondarily crushed and extruded by the first grinding part 104 and the second grinding part 106, they are thrown out of the moving grinding disc group 102 and the first static grinding disc 100 again.

[0196] In this way, a cycle can be formed in the grinding assembly, ensuring that the ingredients can be crushed and ground multiple times, thereby achieving the complete crushing of the ingredients and ensuring the fineness of the crushing of the ingredients.

[0197] In summary, for the grinding assembly provided in the embodiment of the present invention, a dynamic grinding disc group 102 is rotatably arranged in the first static grinding disc 100, a first grinding part 104 is arranged on the outer side wall of the dynamic grinding disc group 102, and a second grinding part 106 is arranged on the inner side wall of the first static grinding disc 100. When the dynamic grinding disc group 102 rotates relative to the first static grinding disc 100, a comprehensive effect such as strong and reciprocating hydraulic shear, friction, centrifugal extrusion, liquid flow collision, and cavitation effect of instantaneous bubble collapse can be formed between the first grinding part 104 and the second grinding part 106 on the food material, so as to realize the crushing of the food material. At the same time, since the crushing of the food material mainly depends on the first grinding part 104 and the second grinding part 106, the disadvantages brought about by mainly crushing the food material by a crushing knife in the related art can be avoided. For example, through the cooperation of the first grinding part 104 and the second grinding part 106, the problem of high noise caused by the rotation of the blade can be solved, and the use frequency of the blade can be reduced, thereby reducing the possibility of blade passivation. When the food material is thrown out, due to the continuous high-speed rotation of the dynamic grinding disc group 102, a certain negative pressure will be formed inside the dynamic grinding disc group 102, and the thrown-out food material can be sucked into the dynamic grinding disc group 102 again. After being secondary crushed and extruded by the first grinding part 104 and the second grinding part 106, it is thrown out of the dynamic grinding disc group 102 and the first static grinding disc 100 again. In this way, a cycle can be formed in the grinding assembly, ensuring that the food material can be crushed and ground multiple times, thereby realizing the complete crushing of the food material and ensuring the fineness of the crushing of the food material.

[0198] Secondly, for the grinding assembly provided in the embodiment of the present invention, through the precise cooperation of the dynamic grinding disc group 102 with the first static grinding disc 100 and the second static grinding disc 128, the dynamic grinding disc group 102 rotates at a high speed to generate a strong centrifugal force, and a very strong negative pressure area is formed in the center of the dynamic grinding disc group 102. The food material is sucked in from the second static grinding disc 128. Under the action of the centrifugal force, the food material diffuses from the center to the periphery. During the process of diffusing to the periphery, the food material is first subjected to the primary crushing action of the first crushing knife 130, and is subjected to extrusion and shear force in the narrow gap between the dynamic grinding disc group 102 and the cutting teeth 140, and then enters the narrow gap between the dynamic grinding disc group 102, the first static grinding disc 100 and the second static grinding disc 128. Under the action of mechanical force and hydrodynamics effect, great shear, friction, impact and mutual collision and friction between the food materials are generated, so that the dispersed phase particles or droplets are broken.

[0199] As the linear velocity of the dynamic grinding disc group 102 gradually increases from the inside to the outside, the crushing environment is continuously improved. During the process of the food material moving towards the outer circle, it is subjected to stronger and stronger shear, friction, impact and collision and other actions, and is crushed finer and finer, so as to achieve the purpose of homogeneous emulsification.

[0200] Meanwhile, in the central negative pressure area of the moving grinding disc group 102, when the pressure is lower than the saturated vapor pressure of the liquid, a large number of bubbles are generated. When the bubbles flow with the liquid to the narrow gap between the moving grinding disc group 102 and the basket fixed crushing teeth and are shredded, or collapse as the pressure increases. At the moment of collapse, a micro-jet is formed in the center of the bubble. The jet velocity can reach 100 m / s or even 300 m / s, and the impact force generated can be close to 200 MPa. This is the cavitation effect. The powerful pressure wave of the cavitation effect can crush soft ingredients and disperse fine particles of hard ingredients, playing a role in homogenization and emulsification, thereby improving the absorption and taste of the ingredients.

[0201] The embodiment of the present invention also provides a food processing device, including a cup body 10 and a grinding assembly as provided in the embodiment of the first aspect of the present invention.

[0202] In the embodiment of the present invention, the cup body 10 can be detachably connected to the base through forms such as threaded connection. For example, an internal thread section can be provided on the inner side wall of the bottom of the cup body 10, and an external thread section can be provided on the outer side wall of the top of the base. The detachable connection between the cup body 10 and the base can be achieved through the threaded connection between the internal thread section and the external thread section.

[0203] The food processing device provided by the embodiment of the present invention can improve the grinding accuracy of the food processing device for ingredients by setting the grinding assembly provided by the embodiment of the first aspect of the present invention. At the same time, since the crushing of the ingredients mainly relies on the first grinding part 104 and the second grinding part 106, the disadvantages brought by mainly crushing the ingredients by a crushing knife in the related art can be avoided. For example, it can solve the problem of loud noise caused by the rotation of the blade, and can also reduce the use frequency of the blade, thereby reducing the possibility of blade passivation.
