[0054] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0055] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0056] The following is in conjunction with the appendix Figure 1-6 This application describes a food processing apparatus 100 according to some embodiments.

[0057] Please refer to Figure 1 The food processing equipment 100 includes: a housing 10 and a stirring component 20.

[0058] It is understood that the food processing equipment 100 of this application can be a meat grinder, a mixer, a high-speed blender or other device that can crush or mix ingredients, and is not limited herein.

[0059] Please refer to Figure 1 The outer casing 10 has a stirring chamber 14. The bottom wall 141 of the stirring chamber 14 is provided with a first positioning engagement part 15. The stirring element 20 is rotatably installed in the stirring chamber 14 and is provided with a second positioning engagement part 21 that positions and engages with the first positioning engagement part 15. In this way, the stirring element 20 is positioned relative to the bottom wall 141 of the stirring chamber 14 through the positioning engagement of the first positioning engagement part 15 and the second positioning engagement part 21, thereby preventing the stirring element 20 from disengaging from the stirring chamber 14 when rotating.

[0060] It is understood that the positioning and fitting method of the first positioning and fitting part 15 and the second positioning and fitting part 21 can be the positioning and fitting of the protrusion and the groove, or the positioning and fitting of the assembly shaft and the positioning hole, or other positioning and fitting methods, which are not limited here.

[0061] Please refer to Figure 1 and Figure 2 One of the first positioning mating part 15 and the second positioning mating part 21 is provided with a first magnetic attraction mating part 31 and the other is provided with a second magnetic attraction mating part 32, and the first magnetic attraction mating part 31 and the second magnetic attraction mating part 32 are magnetically engaged.

[0062] For example Figure 2 As shown, the first positioning engagement part 15 is provided with a second magnetic engagement member 32, and the second positioning engagement part 21 is provided with a first magnetic engagement member 31. In this way, when the first positioning engagement part 15 and the second positioning engagement part 21 are positioned and engaged, the magnetic engagement of the first magnetic engagement member 31 and the second magnetic engagement member 32 can enhance the positioning engagement strength, thereby reducing the risk of separation between the first positioning engagement part 15 and the second positioning engagement part 21, and thus reducing the risk of the stirring member 20 detaching. Moreover, even if the food causes the first positioning engagement part 15 and the second positioning engagement part 21 to separate when the user places food, quick positioning can still be achieved, thereby improving the user experience.

[0063] According to the food processing device 100 of the present application embodiment, when the first positioning mating part 15 and the second positioning mating part 21 are positioned and mated, the positioning and mating strength can be enhanced by the magnetic attraction of the first magnetic attraction member 31 and the second magnetic attraction member 32, so as to reduce the risk of separation between the first positioning mating part 15 and the second positioning mating part 21, thereby reducing the risk of the stirring member 20 detaching. Moreover, when the user places food, even if the food causes the first positioning mating part 15 and the second positioning mating part 21 to separate, quick positioning can be achieved, thereby improving the user experience.

[0064] In some embodiments, the first magnetic engagement member 31 and the second magnetic engagement member 32 are magnetically engaged in the direction extending along the rotation axis of the stirring member 20. This allows for the positioning engagement of the first positioning engagement part 15 and the second positioning engagement part 21 in the direction extending along the rotation axis of the stirring member 20, thereby enhancing the rotational stability of the stirring member 20.

[0065] It is understood that when the stirring member 20 rotates, it rotates clockwise or counterclockwise around the rotation axis, that is, the force direction of the stirring member 20 is clockwise or counterclockwise. Therefore, this application sets the first magnetic attraction component 31 and the second magnetic attraction component 32 to magnetically engage in the direction of extension of the rotation axis of the stirring member 20, so that the magnetic attraction direction of the first magnetic attraction component 31 and the second magnetic attraction component 32 will not interfere with the rotation direction of the stirring member 20, thereby reducing the influence of the magnetic attraction of the first magnetic attraction component 31 and the second magnetic attraction component 32 on the rotation of the stirring member 20.

[0066] In some embodiments, such as Figure 1 and Figure 2As shown, the first magnetic attraction component 31 is disposed at one end of the stirring component 20 facing the bottom wall 141 of the stirring chamber 14, and the second magnetic attraction component 32 is disposed at the bottom wall 141 of the stirring chamber 14.

[0067] For example, in some implementations, the first magnetic attraction component 31 is disposed on the second positioning engagement part 21, and the second magnetic attraction component 32 is disposed on the first positioning engagement part 15. Therefore, the second positioning engagement part 21 is disposed at one end of the stirring member 20 facing the bottom wall 141 of the stirring chamber 14, and the first positioning engagement part 15 is disposed on the bottom wall 141 of the stirring chamber 14. This makes it easier to reduce the difficulty of setting the first magnetic attraction component 31 and the second magnetic attraction component 32, and also facilitates the setting of the first magnetic attraction component 31 and the second magnetic attraction component 32 in the extension direction of the rotation axis of the stirring member 20 for magnetic attraction engagement.

[0068] In some embodiments, the first magnetic engagement member 31 and the second magnetic engagement member 32 are magnetically engaged in the radial direction of the stirring member 20. This enables the first positioning engagement portion 15 and the second positioning engagement portion 21 to be positioned in the radial direction of the stirring member 20, thereby enhancing the rotational stability of the stirring member 20.

[0069] In some embodiments, such as Figure 3 and Figure 4 As shown, the first magnetic attraction component 31 is disposed on the stirring component 20, and the second magnetic attraction component 32 is disposed around the first magnetic attraction component 31 on the radial outer side.

[0070] For example, the second positioning fitting part 21 is disposed at one end of the stirring member 20 facing the bottom wall 141 of the stirring chamber 14. The first magnetic attraction fitting part 31 is fixedly sleeved on the second positioning fitting part 21. The first positioning fitting part 15 is disposed on the bottom wall 141 of the stirring chamber 14. The second magnetic attraction fitting part 32 is fixedly sleeved on the first positioning fitting part 15. That is, both the first magnetic attraction fitting part 31 and the second magnetic attraction fitting part 32 are constructed as annular parts. When the first positioning fitting part 15 and the second positioning fitting part 21 are positioned and engaged, the second magnetic attraction fitting part 32 surrounds the first magnetic attraction fitting part 31 radially outside the first magnetic attraction fitting part 31. In this way, the first positioning fitting part 15 and the second positioning fitting part 21 can be positioned and engaged radially in the stirring member 20, thereby enhancing the rotational stability of the stirring member 20.

[0071] In some embodiments, one of the first positioning mating part 15 and the second positioning mating part 21 is configured as a positioning protrusion 41 and the other is configured as a positioning groove 42, with the positioning protrusion 41 inserted into the positioning groove 42.

[0072] Therefore, by inserting the positioning protrusion 41 into the positioning groove 42, the positioning protrusion 41 and the positioning groove 42 can be positioned and engaged, thereby achieving the positioning engagement between the stirring component 20 and the bottom wall 141 of the stirring chamber 14. This enhances the rotational stability of the stirring component 20 and reduces the risk of the stirring component 20 detaching from the stirring chamber 14. This approach simplifies the positioning engagement between the stirring component 20 and the bottom wall 141 of the stirring chamber 14, and the arrangement of the positioning protrusion 41 and the positioning groove 42 is relatively simple, reducing design complexity and production costs.

[0073] For example Figure 2 and Figure 4 As shown, the positioning groove 42 can be set on the bottom wall 141 of the stirring chamber 14, and the positioning groove 42 is open towards the stirring member 20 in the direction of the rotation axis of the stirring member 20. The positioning protrusion 41 is set on one end of the stirring member 20 facing the bottom wall 141 of the stirring chamber 14. In this way, when the stirring member 20 is positioned and engaged with the bottom wall 141 of the stirring chamber 14, the positioning protrusion 41 can be directly inserted into the positioning groove 42 to realize the positioning and engagement of the stirring member 20 with the bottom wall 141 of the stirring chamber 14, thereby enhancing the rotational stability of the stirring member 20 and reducing the risk of the stirring member 20 detaching from the stirring chamber 14.

[0074] Or such as Figure 5 and Figure 6 As shown, the positioning groove 42 can be disposed at one end of the stirring member 20 facing the bottom wall 141 of the stirring chamber 14, and the positioning groove 42 is open towards the bottom wall 141 of the stirring chamber 14 in the direction of the rotation axis of the stirring member 20. The positioning protrusion 41 is disposed on the bottom wall 141 of the stirring chamber 14, and the positioning protrusion 41 protrudes towards the stirring member 20 in the direction of the rotation axis of the stirring member 20. In this way, when the stirring member 20 is positioned and engaged with the bottom wall 141 of the stirring chamber 14, the positioning protrusion 41 can be directly inserted into the positioning groove 42 to achieve the positioning and engagement of the stirring member 20 with the bottom wall 141 of the stirring chamber 14, thereby enhancing the rotational stability of the stirring member 20 and reducing the risk of the stirring member 20 dislodging from the stirring chamber 14.

[0075] In some embodiments, a first magnetic attraction member 31 is disposed on a positioning protrusion 41, a second magnetic attraction member 32 is located in a positioning groove 42, and at least a portion of the first magnetic attraction member 31 is inserted into the positioning groove 42.

[0076] Therefore, when the positioning protrusion 41 is inserted into the positioning groove 42, at least a portion of the first magnetic attraction member 31 is inserted into the positioning groove 42 to magnetically engage with the second magnetic attraction member 32, thereby enhancing the magnetic attraction effect of the first magnetic attraction member 31 and the second magnetic attraction member 32.

[0077] In some embodiments, the first magnetic attraction member 31 is disposed at one end of the positioning protrusion 41 facing the bottom wall of the positioning groove 42, and the second magnetic attraction member 32 is disposed on the bottom wall of the positioning groove 42.

[0078] It is understandable that when the positioning protrusion 41 is inserted into the positioning groove 42, the end of the positioning protrusion 41 facing the bottom wall of the positioning groove 42 is opposite to the bottom wall of the positioning groove 42. This facilitates the magnetic attraction between the first magnetic attraction component 31 and the second magnetic attraction component 32 in the axial direction of the stirring component 20, and also facilitates reducing the distance between the first magnetic attraction component 31 and the second magnetic attraction component 32, thereby enhancing the magnetic attraction effect of the first magnetic attraction component 31 and the second magnetic attraction component 32.

[0079] For example Figure 1 and Figure 2 As shown, the positioning groove 42 can be disposed on the bottom wall 141 of the stirring chamber 14, and the positioning groove 42 is open toward the stirring member 20 in the direction of the rotation axis of the stirring member 20. The second magnetic attraction fitting member 32 is disposed on the bottom wall of the positioning groove 42, the positioning protrusion 41 is disposed on one end of the stirring member 20 toward the bottom wall 141 of the stirring chamber 14, and the first magnetic attraction fitting member 31 is disposed on one end of the positioning protrusion 41 toward the bottom wall of the positioning groove 42.

[0080] In this way, when the stirring component 20 is positioned and engaged with the bottom wall 141 of the stirring chamber 14, the positioning protrusion 41 can be directly inserted into the positioning groove 42 to achieve the positioning engagement between the stirring component 20 and the bottom wall 141 of the stirring chamber 14, thereby enhancing the rotational stability of the stirring component 20 and reducing the risk of the stirring component 20 detaching from the stirring chamber 14. At the same time, during the process of the positioning protrusion 41 being inserted into the positioning groove 42, the first magnetic attraction component 31 and the second magnetic attraction component 32 gradually approach each other, that is, the magnetic attraction between the first magnetic attraction component 31 and the second magnetic attraction component 32 gradually increases, thereby playing a role in assisting the insertion of the positioning protrusion 41 into the positioning groove 42. In particular, after the positioning protrusion 41 is inserted into the positioning groove 42, the magnetic attraction between the first magnetic attraction component 31 and the second magnetic attraction component 32 can be used to enhance the insertion stability of the positioning protrusion 41 into the positioning groove 42.

[0081] For example Figure 5 and Figure 6 As shown, the positioning groove 42 can be disposed at one end of the stirring member 20 facing the bottom wall 141 of the stirring chamber 14. The first magnetic attraction fitting member 31 is disposed on the bottom wall of the positioning groove 42, and the positioning groove 42 is open towards the bottom wall 141 of the stirring chamber 14 in the direction of the rotation axis of the stirring member 20. The positioning protrusion 41 is disposed on the bottom wall 141 of the stirring chamber 14, and the positioning protrusion 41 protrudes towards the stirring member 20 in the direction of the rotation axis of the stirring member 20. The second magnetic attraction fitting member 32 is disposed at one end of the positioning protrusion 41 facing the positioning groove 42.

[0082] In this way, when the stirring component 20 is positioned and engaged with the bottom wall 141 of the stirring chamber 14, the positioning protrusion 41 can be directly inserted into the positioning groove 42 to achieve the positioning engagement between the stirring component 20 and the bottom wall 141 of the stirring chamber 14, thereby enhancing the rotational stability of the stirring component 20 and reducing the risk of the stirring component 20 detaching from the stirring chamber 14. At the same time, during the process of the positioning protrusion 41 being inserted into the positioning groove 42, the first magnetic attraction component 31 and the second magnetic attraction component 32 gradually approach each other, that is, the magnetic attraction between the first magnetic attraction component 31 and the second magnetic attraction component 32 gradually increases, thereby playing a role in assisting the insertion of the positioning protrusion 41 into the positioning groove 42. In particular, after the positioning protrusion 41 is inserted into the positioning groove 42, the magnetic attraction between the first magnetic attraction component 31 and the second magnetic attraction component 32 can be used to enhance the insertion stability of the positioning protrusion 41 into the positioning groove 42.

[0083] In some embodiments, the food processing device further includes a spacer 44, which is connected to the inner wall of the positioning protrusion 41 and / or the positioning groove 42, and at least a portion of the spacer 44 is located between the first magnetic engagement member 31 and the second magnetic engagement member 32.

[0084] Therefore, the first magnetic attraction component 31 and the second magnetic attraction component 32 will not directly attract each other, that is, the first magnetic attraction component 31 and the second magnetic attraction component 32 are indirectly attracted. In this way, the influence of the magnetic attraction force between the first magnetic attraction component 31 and the second magnetic attraction component 32 on the rotation of the stirring component 20 can be reduced.

[0085] In some embodiments, a first mounting cavity 411 is provided in the positioning protrusion 41, a first magnetic attraction member 31 is located in the first mounting cavity 411, the bottom wall of the first mounting cavity 411 is formed as a spacer 44, and a second magnetic attraction member 32 is located in the positioning groove 42.

[0086] Therefore, the first magnetic attraction component 31 can be installed in the first mounting cavity 411 to reduce the installation difficulty of the first magnetic attraction component 31. The bottom wall of the first mounting cavity 411 is formed as a spacer 44 so that the first magnetic attraction component 31 and the second magnetic attraction component 32 can be separated by the bottom wall of the first mounting cavity 411, so that the first magnetic attraction component 31 and the second magnetic attraction component 32 are indirectly attracted. In this way, the influence of the magnetic attraction force between the first magnetic attraction component 31 and the second magnetic attraction component 32 on the rotation of the stirring component 20 can be reduced.

[0087] In some embodiments, the positioning protrusion 41 is provided with a second magnetic attraction member 32, the positioning groove 42 is provided with a spacer 44, the first magnetic attraction member 31 is installed on the spacer 44, and at least a portion of the spacer 44 is located between the first magnetic attraction member 31 and the second magnetic attraction member 32.

[0088] Therefore, when the positioning protrusion 41 is inserted into the positioning groove 42, the first magnetic attraction component 31 and the second magnetic attraction component 32 will not directly attract each other, that is, the first magnetic attraction component 31 and the second magnetic attraction component 32 are indirectly attracted. In this way, the influence of the magnetic attraction force between the first magnetic attraction component 31 and the second magnetic attraction component 32 on the rotation of the stirring component 20 can be reduced.

[0089] In some embodiments, the spacer 44 has a mating protrusion 43 at one end facing the second magnetic mating member 32, and the mating protrusion 43 is used to abut against the positioning protrusion 41.

[0090] Therefore, by setting the protrusion 43, the contact area between the positioning protrusion 41 and the spacer 44 can be reduced, thereby reducing the friction between the positioning protrusion 41 and the mating protrusion 43 when the positioning protrusion 41 and the positioning groove 42 rotate relative to each other.

[0091] In some embodiments, such as Figure 2 As shown, the positioning groove 42 includes a first chamber and a second chamber spaced apart axially in the stirring member 20. The positioning protrusion 41 is inserted into the first chamber, and the second magnetic engagement member 32 is located in the second chamber.

[0092] It is understandable that the positioning protrusion 41 is positioned and engaged with the first chamber, and the second magnetic engaging component 32 is located in the second chamber, so that the second magnetic engaging component 32 is spaced apart from the positioning protrusion 41. In this way, the first magnetic engaging component 31 and the second magnetic engaging component 32 will not directly engage, that is, the first magnetic engaging component 31 and the second magnetic engaging component 32 are indirectly engaged. This can reduce the influence of the magnetic attraction between the first magnetic engaging component 31 and the second magnetic engaging component 32 on the rotation of the stirring component 20.

[0093] In some embodiments, such as Figure 1 As shown, the side wall of the second chamber near the first chamber is provided with a mating protrusion 43 that protrudes toward the first chamber, and the second magnetic mating member 32 is disposed opposite to the mating protrusion 43.

[0094] Therefore, by setting the matching protrusion 43, the contact area between the positioning protrusion 41 and the side wall of the second chamber near the first chamber can be reduced, thereby reducing the friction between the positioning protrusion 41 and the matching protrusion 43 when the positioning protrusion 41 and the positioning groove 42 rotate relative to each other.

[0095] In some embodiments, the second magnetic coupling member 32 is mounted on the bottom wall of the first chamber.

[0096] Therefore, when the positioning protrusion 41 is inserted into the first chamber, the second magnetic coupling member 32 magnetically attracts the first magnetic coupling member 31, and the second magnetic coupling member 32 is installed on the bottom wall of the first chamber, which makes it easier to reduce the difficulty of setting the second magnetic coupling member 32.

[0097] In some embodiments, such as Figure 2 and Figure 4 As shown, at least a portion of the positioning protrusion 41 is located on the agitator 30 along the axial direction of the agitator 20. This reduces the impact of the positioning protrusion 41 on the axial dimension of the agitator 20.

[0098] In some embodiments, such as Figure 2 and Figure 4 As shown, the stirring element 20 is sleeved on one end of the positioning protrusion 41, and the other end of the positioning protrusion 41 protrudes out of the stirring element 20 in the axial direction. The spacer 44 is located inside the positioning protrusion 41.

[0099] Therefore, it is convenient to reduce the impact of the positioning protrusion 41 on the radial and axial dimensions of the stirring component 20, and the spacer 44 can be arranged and installed using the space inside the positioning protrusion 41, which helps to reduce the space occupied by the spacer 44 on the outside of the positioning protrusion 41.

[0100] In some embodiments, such as Figure 3 and Figure 4 As shown, the first magnetic attraction component 31 is mounted on the positioning protrusion 41, and the second magnetic attraction component 32 is disposed within the positioning groove 42 and surrounds the first magnetic attraction component 31. Thus, magnetic attraction between the first magnetic attraction component 31 and the second magnetic attraction component 32 can be achieved radially within the stirring component 20.

[0101] In some embodiments, such as Figure 3 and Figure 4 As shown, the first magnetic attraction component 31 is arranged around the center line of the positioning protrusion 41, and the second magnetic attraction component 32 is arranged on the side wall of the positioning groove 42 and around the first magnetic attraction component 31.

[0102] For example Figure 3 and Figure 4 As shown, the positioning groove 42 can be set on the bottom wall 141 of the stirring chamber 14, and the positioning groove 42 is open towards the stirring member 20 in the direction of the rotation axis of the stirring member 20. The second magnetic attraction fitting member 32 is set on the side wall of the positioning groove 42, and the positioning protrusion 41 is set on one end of the stirring member 20 facing the bottom wall 141 of the stirring chamber 14. The first magnetic attraction fitting member 31 is circumferentially arranged around the positioning protrusion 41.

[0103] In this way, when the stirring component 20 is positioned and engaged with the bottom wall 141 of the stirring chamber 14, the positioning protrusion 41 can be directly inserted into the positioning groove 42 to achieve the positioning engagement between the stirring component 20 and the bottom wall 141 of the stirring chamber 14, thereby enhancing the rotational stability of the stirring component 20 and reducing the risk of the stirring component 20 detaching from the stirring chamber 14. At the same time, after the positioning protrusion 41 is inserted into the positioning groove 42, the magnetic attraction of the first magnetic attraction component 31 and the second magnetic attraction component 32 can be used to enhance the insertion stability of the positioning protrusion 41 and the positioning groove 42 in the radial direction of the stirring component 20.

[0104] In some embodiments, such as Figure 4 As shown, the second magnetic coupling member 32 defines a positioning guide groove, and the positioning protrusion 41 is inserted into the positioning guide groove. Therefore, when the positioning protrusion 41 is inserted into the positioning groove 42, it can simultaneously be inserted into the positioning guide groove defined by the second magnetic coupling member 32. This allows for simultaneous positioning engagement between the second magnetic coupling member 32 and the positioning protrusion 41, and also enables magnetic engagement between the second magnetic coupling member 32 and the first magnetic coupling member.

[0105] In some embodiments, the second magnetic coupling member 32 is mounted on the side wall of the positioning groove 42. This reduces the difficulty of setting the second magnetic coupling member 32 and facilitates the arrangement of the second magnetic coupling member 32 around the first magnetic coupling member 31.

[0106] In some embodiments, the positioning groove 42 includes a first chamber and a second chamber that are radially spaced apart from each other in the stirring member 20, the positioning protrusion 41 is inserted into the first chamber, and the second magnetic engagement member 32 is located in the second chamber.

[0107] It is understandable that the positioning protrusion 41 is positioned and engaged with the first chamber, and the second magnetic engaging component 32 is located in the second chamber, so that the second magnetic engaging component 32 is spaced apart from the positioning protrusion 41. In this way, the first magnetic engaging component 31 and the second magnetic engaging component 32 will not directly engage, that is, the first magnetic engaging component 31 and the second magnetic engaging component 32 are indirectly engaged. This can reduce the influence of the magnetic attraction between the first magnetic engaging component 31 and the second magnetic engaging component 32 on the rotation of the stirring component 20.

[0108] In some embodiments, such as Figure 2 , Figure 4 and Figure 6 As shown, a first mounting cavity 411 is formed inside the positioning protrusion 41, and the first magnetic attraction component 31 is located inside the first mounting cavity 411.

[0109] Therefore, the first magnetic attraction component 31 can be installed in the first mounting cavity 411, thereby reducing the difficulty of setting the first magnetic attraction component 31. The first magnetic attraction component 31 can be bonded to the first mounting cavity 411. For example, the first magnetic attraction component 31 can be installed and fixed by injecting glue into the first mounting cavity 411, thereby enhancing the structural stability of the first magnetic attraction component 31.

[0110] In some embodiments, such as Figure 4 As shown, the first mounting cavity 411 is constructed as an annular cavity surrounding the center line of the positioning protrusion 41. The first magnetic coupling member 31 is located in the annular cavity, and when the positioning protrusion 41 is inserted into the positioning groove 42, at least a portion of the annular cavity is located in the positioning groove 42 so that the first magnetic coupling member 31 and the second magnetic coupling member 32 magnetically engage.

[0111] Therefore, when the positioning protrusion 41 is inserted into the positioning groove 42, at least a portion of the annular cavity is located within the positioning groove 42 so that the first magnetic attraction member 31 and the second magnetic attraction member 32 magnetically engage, thereby enhancing the magnetic attraction stability of the first magnetic attraction member 31 and the second magnetic attraction member 32.

[0112] In some embodiments, such as Figure 2 and Figure 6 As shown, a second mounting cavity 421 is formed in the bottom wall of the positioning groove 42, and the second magnetic attraction component 32 is located in the second mounting cavity 421.

[0113] This allows the second magnetic accommodating component 32 to be installed on the bottom wall of the positioning groove 42, and also reduces the difficulty of setting the second magnetic accommodating component 32. The second magnetic accommodating component 32 can be bonded to the second mounting cavity 421. For example, the second magnetic accommodating component 32 can be installed and fixed by injecting glue into the second mounting cavity 421, thereby enhancing the structural stability of the second magnetic accommodating component 32.

[0114] In some embodiments, such as Figure 4 As shown, a second mounting cavity 421 is formed in the side wall of the positioning groove 42, and the second magnetic attraction component 32 is located in the second mounting cavity 421.

[0115] This allows the second magnetic accommodating component 32 to be installed on the side wall of the positioning groove 42, and also reduces the difficulty of setting the second magnetic accommodating component 32. The second magnetic accommodating component 32 can be bonded to the second mounting cavity 421. For example, the second magnetic accommodating component 32 can be installed and fixed by injecting glue into the second mounting cavity 421, thereby enhancing the structural stability of the second magnetic accommodating component 32.

[0116] In some embodiments, such as Figure 5As shown, the bottom wall 141 of the stirring chamber 14 is provided with a guide support portion 16, which is arranged around the first positioning and fitting portion 15, as shown. Figure 6 As shown, the guide support portion 16 has a guide slope 161 formed on the side near the first positioning and mating portion 15 for guiding and mating with the second positioning and mating portion 21.

[0117] Therefore, during the process of the second positioning and mating part 21 moving along the bottom wall 141 of the stirring chamber 14 to position and mate with the first positioning and mating part 15, the guide slope 161 of the guide support part 16 can guide the second positioning and mating part 21, thereby enabling the second positioning and mating part 21 to more easily achieve positioning and mating with the first positioning and mating part 15.

[0118] In some embodiments, a groove is defined between the first positioning mating part 15 and the guide support part 16, and one end of the stirring member 20 facing the bottom wall 141 of the stirring chamber 14 is positioned and mated with the groove.

[0119] For example Figure 6 As shown, the first positioning mating part 15 is constructed as a positioning protrusion 41, and the guide support part 16 is arranged around the positioning protrusion 41 and defines a groove with the positioning protrusion 41. The second positioning mating part 21 is constructed as a positioning groove 42. When the positioning protrusion 41 is inserted into the positioning groove 42, the outer peripheral wall of the positioning groove 42 is inserted into the groove. Thus, the end of the stirring member 20 facing the bottom wall 141 of the stirring chamber 14 can be further positioned and mated with the groove defined between the first positioning mating part 15 and the guide support part 16.

[0120] In some embodiments, the stirring component 20 includes a stirring shaft 22 and a plurality of stirring blades 23. A second positioning and fitting part 21 is disposed on the stirring shaft 22. The plurality of stirring blades 23 are connected to the outer peripheral wall of the stirring shaft 22 and are spaced apart in the axial direction of the stirring shaft 22. The minimum distance from the stirring blade 23 with the smallest distance from the bottom wall 141 of the stirring chamber 14 to the guide support part 16 is the first distance, which is greater than 0.3 mm and less than 2 mm.

[0121] For example Figure 4 As shown, the minimum distance from the stirring blade 23 with the smallest distance from the bottom wall 141 of the stirring chamber 14 to the guide support part 16 is the first distance, which is represented by H1. That is, H1 satisfies: 0.3mm < H1 < 2mm.

[0122] For example, the value of H1 can be 0.31mm, 0.35mm, 0.85mm or 1.5mm. That is, when the minimum distance between the stirring blade 23 with the smallest distance from the bottom wall 141 of the stirring chamber 14 and the guide support 16 is within the above range, interference between the stirring blade 23 with the smallest distance from the bottom wall 141 of the stirring chamber 14 and the guide support 16 can be avoided, thereby protecting the stirring blade 23.

[0123] In some embodiments, the maximum distance from the stirring blade 23, which is closest to the bottom wall 141 of the stirring chamber 14, to the guide support 16 is the second distance, which is greater than 3.3 mm and less than 14 mm.

[0124] For example Figure 4 As shown, the maximum distance from the stirring blade 23, which is closest to the bottom wall 141 of the stirring chamber 14, to the guide support 16 is the second distance, which is represented by H2. That is, H1 satisfies: 3.3mm < H2 < 14mm.

[0125] For example, the value of H2 can be 3.5mm, 4.5mm, 6.85mm or 10mm. That is, when the maximum distance from the stirring blade 23 with the smallest distance from the bottom wall 141 of the stirring chamber 14 to the guide support part 16 is within the above range, the guide support part 16 can guide the second positioning and fitting part 21, thus avoiding the guide support part 16 from being too large in the axial direction of the stirring member 20, thereby reducing the encroachment on the space inside the stirring chamber 14.

[0126] In some embodiments, the ratio of the first distance to the second distance is greater than 0.02 and less than 0.8. That is, H1 / H2 satisfies: 0.02 < H1 / H2 < 0.8.

[0127] For example, the value of H1 / H2 can be 0.03, 0.08, 0.2 or 0.5. That is, when the ratio of the first distance and the second distance meets the above value range, it can avoid the interference between the stirring blade 23 with the smallest distance from the bottom wall 141 of the stirring chamber 14 and the guide support part 16. Moreover, when the guide support part 16 guides the second positioning and fitting part 21, it can avoid the size of the guide support part 16 in the axial direction of the stirring member 20 being too large, thereby reducing the encroachment on the space inside the stirring chamber 14.

[0128] In some embodiments, such as Figure 1 , Figure 3 and Figure 5As shown, the outer casing 10 includes a coaster 12, a cup body 11, and a cup lid 13. The coaster 12 and the cup body 11 are connected to define a stirring chamber 14 with an open upper end. The cup lid 13 is movably mounted on the cup body 11 to open or close the stirring chamber 14. The side of the coaster 12 facing the cup lid 13 forms the bottom wall 141 of the stirring chamber 14.

[0129] In some embodiments, the food processing device 100 further includes a main unit 50, which can be a drive device, such as a drive motor, and the main unit 50 is poweredly connected to the stirring element 20. This facilitates the use of the main unit 50 to drive the stirring element 20 to rotate within the stirring chamber 14, thereby achieving the crushing or stirring of ingredients.

[0130] In some embodiments, one of the first magnetic attraction component 31 and the second magnetic attraction component 32 is a magnet and the other is a metal component.

[0131] For example, the first magnetic attraction component 31 is a magnet, and the second magnetic attraction component 32 is a metal component. This allows the first magnetic attraction component 31 and the second magnetic attraction component 32 to magnetically engage. In particular, the metal component has a lower cost and is simpler to set up, which helps to reduce design costs and assembly difficulty.

[0132] Alternatively, the second magnetic attraction component 32 can be a magnet and the first magnetic attraction component 31 can be a metal part, which can also achieve the same technical effect as described above, and will not be elaborated here.

[0133] It is understood that metal parts refer to metal structures that are not magnetic themselves but can be magnetically attracted to magnets. For example, the material of metal parts can be: iron, cobalt, nickel, manganese or a compound containing any two of the above materials, without limitation.

[0134] In some embodiments, both the first magnetic attraction component 31 and the second magnetic attraction component 32 are magnets.

[0135] It is understandable that the first magnetic attraction component 31 and the second magnetic attraction component 32 can be magnets with opposite polarities attracting each other. This allows the first magnetic attraction component 31 and the second magnetic attraction component 32 to magnetically engage. Since both the first magnetic attraction component 31 and the second magnetic attraction component 32 are magnets, it is easier to enhance the stability of the magnetic engagement of the first magnetic attraction component 31 and the second magnetic attraction component 32, thereby enhancing the positioning engagement strength of the first positioning engagement part 15 and the second positioning engagement part 21, and further enhancing the connection strength between the stirring component 20 and the bottom wall 141 of the stirring chamber 14, so as to reduce the risk of the stirring component 20 detaching and thus improve the user experience.
