DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0033] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0034] like Figure 1As shown, the stirring assembly of this embodiment includes: a base 10, a stirring blade 20 and a magnetic assembly 30. The base 10 has an inner cavity 11, and the stirring blade 20 is arranged on the base 10. The magnetic assembly 30 is arranged in the inner cavity 11, and the magnetic assembly 30 has a first state capable of generating magnetism and a second state without generating magnetism.

[0035] By applying the technical solution of this embodiment, the magnetic component 30 can switch between the first state in which magnetism is generated and the second state in which magnetism is not generated, so that the stirring component can generate magnetism or not. When the stirring component needs to cooperate with the driving member to perform stirring work, the stirring component is placed in the first state; when the stirring component needs to be stored, the stirring component is placed in the second state, in which magnetism is not generated, thereby effectively avoiding the adsorption of metal tableware, such as table knives and forks.

[0036] The stirring blade 20 can be a separate structure connected to the base 10, or can be an integral structure with the base 10. In other embodiments not shown in the figures, the stirring assembly may not include the stirring blade 20, and the stirring function is only achieved by the base 10, and the base 10 can be set to a shape that can achieve the stirring function.

[0037] like Figures 1 to 3 As shown, in this embodiment, the magnetic assembly 30 is preferably a permanent magnetic chuck, which includes a first magnetic member 31 and a second magnetic member 32. The first magnetic member 31 is fixedly arranged, and the second magnetic member 32 is rotatably arranged, that is, the two can generate relative motion. Figure 2 As shown, when the N pole of the first magnetic part 31 and the N pole of the second magnetic part 32 are located on the same side and the S pole of the first magnetic part and the S pole of the second magnetic part are located on the same side, the magnetic assembly 30 is in the first state, and at this time, the magnetic assembly 30 can generate magnetism. Specifically, the magnetic lines of force come out from the N poles of the first magnetic part 31 and the second magnetic part 32, pass through the yoke, pass through the ferromagnetic workpiece, and then return to the yoke to enter the S poles of the first magnetic part 31 and the second magnetic part 32. In this way, the stirring assembly can be firmly sucked onto the bottom surface of the inner pot by cooperating with the magnetic suction sheet of the driving part 3 located under the inner pot. When the motor of the driving part 3 drives the magnetic suction sheet to rotate, the stirring blades of the stirring assembly will also rotate with the rotation of the magnetic suction sheet, thereby achieving the purpose of stirring the food in the pot.

[0038] like Figure 3 As shown, when the N pole of the first magnetic member 31 and the S pole of the second magnetic member 32 are located on the same side and the S pole of the first magnetic member 31 and the N pole of the second magnetic member 32 are located on the same side, the magnetic assembly 30 is in the second state, at which time the magnetic assembly 30 does not generate magnetism. The magnetic lines of force do not reach the working pole surface of the magnetic assembly 30 ( Figure 3The bottom surface in the middle) forms a closed loop of the magnetic circuit inside the magnetic assembly 30, and almost no magnetic lines of force come out from the working pole surface of the magnetic assembly 30, so no suction is generated on the workpiece. At this time, unloading can be smoothly achieved, that is, taken out from the cooking cavity of the pot body 1.

[0039] In this embodiment, the first magnetic member 31 is arranged above the second magnetic member 32. Of course, the relative positions between the two can also be interchanged. The arrangement positions of the first magnetic member and the second magnetic member 32 are not limited to the above manner, as long as they can generate relative movement to switch the magnetic state of the magnetic assembly 30.

[0040] In order to facilitate switching of the magnetic state of the magnetic assembly 30, in this embodiment, Figures 1 to 3 As shown, the magnetic assembly 30 also includes a knob structure 321 disposed on the second magnetic member 32, and the second magnetic member 32 is rotated by the knob structure 321. Of course, the knob structure 321 can be an independent structure connected to the second magnetic member 32, or the two can be an integrally formed structure. In this embodiment, the second magnetic member 32 is disc-shaped. During actual operation, the knob structure 321 needs to be rotated 180° to complete the adjustment of the position of the second magnetic member 32, so that the N pole and S pole of the first magnetic member 31 and the second magnetic member 32 are located on the same side and become on the opposite side.

[0041] It should be noted that any magnetic assembly 30 that can switch between a magnetic state and a non-magnetic state can be used and is also within the protection scope of the present application. For example, in an embodiment not shown in the figure, the magnetic assembly includes an electromagnet, a power supply for powering the electromagnet, and a switch. When the switch is closed, the power supply powers the electromagnet, and the magnetic assembly is in a first state. When the switch is disconnected, the power supply does not power the electromagnet, and the magnetic assembly is in a second state.

[0042] In this embodiment, if Figure 1 As shown, the base 10 includes a shell 12 and a seat 13. The bottom of the shell 12 is provided with an opening, and the seat 13 blocks the opening. The inner cavity 11 is formed between the shell 12 and the seat 13. The above structure is easy to process and easy to implement. The shell 12 and the seat 13 can be connected together in various ways, such as by fasteners such as screws, or by bonding, ultrasonic welding, etc.

[0043] like Figure 1 , Figure 4 and Figure 6As shown, a mounting hole 14 is provided on the housing 12, the magnetic assembly 30 has a connecting shaft 322 connected to the second magnetic member 32, and the knob structure 321 has a connecting sleeve 323, and the connecting sleeve 323 extends into the inner cavity 11 through the mounting hole 14 and is sleeved on the connecting shaft 322. In this way, the mounting hole 14 can avoid the connecting shaft 322 and the connecting sleeve 323, thereby facilitating the connection between the two. In this embodiment, the connecting shaft 322 is a flat shaft with a transmission section, and the inner wall of the connecting sleeve 323 is adapted to the side of the connecting shaft 322 and also has a transmission section. Furthermore, when the knob structure 321 rotates, the connecting shaft 322 rotates with the knob structure 321, thereby driving the second magnetic member 32 to rotate.

[0044] like Figure 4 and Figure 6 As shown, the mounting hole 14 is a stepped hole, the stepped hole forms a first stepped surface 141, and a second stepped surface 324 is formed on the circumferential side wall of the knob structure 321. In this way, it is convenient to set a sealing structure 34 between the mounting hole and the knob structure 321. In this embodiment, the magnetic assembly 30 also includes a sealing structure 34 arranged between the first stepped surface 141 and the second stepped surface 324. The sealing structure 34 ensures the sealing effect between the mounting hole 14 and the knob structure 321.

[0045] In order to facilitate the positioning of the magnetic assembly 30 in the housing 12, as shown in FIG. Figure 1 As shown, a positioning member 121 is disposed in the housing 12 , for example, the positioning member 121 is integrally formed, and the magnetic assembly 30 is fixed in the inner cavity 11 through the positioning member 121 and the seat body 13 .

[0046] Considering that the entire base 10 will rotate, in order to reduce the friction between the base 13 and other components, a rib structure is provided on the surface of the base 13 away from the inner cavity 11 , and the rib structure is preferably integrally formed on the base 13 .

[0047] In this embodiment, if Figure 1 and Figure 4 As shown, the stirring assembly also includes a wear-resistant base 40, the base 10 is rotatably connected to the wear-resistant base 40, and the wear-resistant base 40 is arranged on the side of the base 13 away from the inner cavity. The wear-resistant base 40 is clamped between the base 10 and the inner pot, so that the stirring blade 20 will not directly rub the inner surface of the inner pot when working. When the base 10 is taken out of the inner pot, the wear-resistant base 40 can be taken out together with the base 10, which will not affect the removal of cooked food, such as serving rice or making soup.

[0048] like Figure 1As shown, a through hole 131 is provided on the seat body 13, and the wear-resistant base 40 includes a plate body 41 and a connecting column 42 provided on the plate body 41. The connecting column 42 passes through the through hole 131, and a clamping portion 421 is provided at the end of the connecting column 42. The wear-resistant base 40 is rotatably connected to the seat body 13 through the clamping portion 421. The setting of the clamping portion 421 prevents the wear-resistant base 40 from being separated from the seat body 13. Preferably, a sealing member is also provided in the through hole 131 to seal the gap between the through hole 131 and the connecting column 42. The plate body 41 and the connecting column 42 can be connected to each other or integrally formed.

[0049] like Figure 1 , Figure 4 and Figure 6 As shown, in this embodiment, the stirring assembly further includes an elastic seal 50, which is sleeved outside the connecting column 42 and seals the gap between the through hole 131 and the connecting column 42. The sealing effect between the connecting column 42 and the through hole 131 is ensured. Figure 1 As shown, a positioning groove 33 is provided on the surface of the magnetic assembly 30 facing the base 13, and the clamping portion 421 extends into the positioning groove 33. The positioning groove 33 can relatively determine the position between the magnetic assembly 30 and the connecting column 42, thereby ensuring smooth rotation between the base 10 and the wear-resistant base 40.

[0050] The present application also provides a cooking utensil, such as Figure 4 and Figure 5 As shown, the cooking utensil of this embodiment includes a pot body 1, a stirring assembly 2 arranged in the cooking cavity of the pot body 1, and a driving member 3 for driving the stirring assembly 2 to rotate, and the stirring assembly is the above-mentioned stirring assembly. The driving member 3 includes a motor and a magnetic sheet arranged on the output shaft of the motor. The above-mentioned stirring assembly can effectively avoid the adsorption of metal tableware, such as table knives and forks. In this embodiment, the cooking utensil is an electric pressure cooker. Of course, in other embodiments not shown, the cooking utensil can also be an electric rice cooker, a low-pressure rice cooker, a soymilk maker, a food processor, an electric stew pot and other products.

[0051] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0052] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used herein are interpreted accordingly.

[0053] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
