[0002] Most of the existing food processors on the market have a reservation function, which can make food according to user needs. The existing production method is: water and corresponding food materials are placed in the cup body of the food processor in advance. When the set reservation time arrives, the control system on the food processor controls the heating module to heat to produce the corresponding food. Because this operation needs to soak the food materials in water for a long time, it will result in poor taste of the food, especially in summer, when the outside temperature is high, the food materials soaked in water for a long time will cause the food to have an odor, which will affect the taste and even the health of the user.
[0003] At present, some automatic feeding mechanisms appear on the market, which use the impact force generated by the vortex in the stirring cup to open the feeding mechanism, and in order to obtain sufficient impact force, the feeding pusher needs to extend to the bottom of the stirring cup, resulting in a bulky overall mechanism. At the same time, since the opening and closing of the feeding mechanism is easily affected by the water flow, the feeding mechanism cannot effectively maintain the open state, and problems such as food materials not falling normally or food materials falling being interrupted are prone to occur.

[0006] In the magnetic pneumatic material dropping mechanism, the air pressure change generated by the heating cavity during heating drives the push rod assembly to move the second magnet away from the discharge channel, changes the distance between the first magnet and the second magnet, and makes the first magnet and the second magnet repel each other, thereby driving the push rod assembly to move away from the discharge channel to open the discharge channel.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application.
[0030] Referring to Figure 1 , Figure 2 and Figure 3The application discloses a magnetic pneumatic material dropping mechanism. The magnetic pneumatic material dropping mechanism comprises a cup cover 1, a material bin 2, a push rod assembly 3 and a magnetic assembly 4. Preferably, the cup cover 1 is provided with a heating cavity 11. Optionally, the cup cover 1 can be a cup cover 1 of a heatable container. Optionally, the cup cover 1 can be a cup cover 1 of a cup body of a blender, a soybean milk machine and a food processor. In this way, the heating cavity 11 can be the inner cavity of the cup body of the blender, the soybean milk machine and the food processor. Optionally, the cup cover 1 can also be the cover of a pot body of an electric rice cooker, an electric rice boiler, an electric boiling pot, a soup pot and a stew pot. In this way, the heating cavity 11 can be the inner cavity of the pot body of the electric rice cooker, the electric rice boiler, the electric boiling pot, the soup pot and the stew pot. Preferably, the material bin 2 is arranged on the cup cover 1. An internal part of the material bin 2 is provided with a storage cavity 21. A discharge channel 22 is arranged between the storage cavity 21 and the heating cavity 11. That is, when the discharge channel 22 is in an open state, the storage cavity 21 and the heating cavity 11 can be communicated. When the discharge channel 22 is in a closed state, the storage cavity 21 and the heating cavity 11 can be cut off. The push rod assembly 3 is connected to the discharge channel 22 in cooperation and can move relative to the discharge channel 22. Optionally, the push rod assembly 3 is connected to the discharge channel 22 in cooperation so that the push rod assembly 3 blocks the discharge channel 22 and drives the discharge channel 22 to be in the closed state. When it is needed to open the discharge channel 22, the push rod assembly 3 is driven to move relative to the material bin 2 so as to open the discharge channel 22, thereby connecting the storage cavity 21 and the heating cavity 11. The magnetic assembly 4 comprises a first magnet 41 and a second magnet 42. The first magnet 41 is arranged on the material bin 2. The second magnet 42 is arranged on the push rod assembly 3. When the air pressure of the heating cavity 11 is greater than a threshold value, the push rod assembly 3 drives the second magnet 42 to move away from the discharge channel 22 under the action of the air pressure of the heating cavity 11. The first magnet 41 and the second magnet 42 can be repelled from each other, thereby opening the discharge channel 22. That is, when the second magnet 42 moves away from the discharge channel 22 relative to the first magnet 41, the first magnet 41 and the second magnet 42 can be repelled from each other, thereby driving the push rod assembly 3 to move away from the discharge channel 22, so as to open the discharge channel 22.Preferably, the air pressure change generated by the heating cavity 11 during heating drives the push rod assembly 3 to move the second magnet 42 away from the discharge channel 22, changes the distance between the first magnet 41 and the second magnet 42, and makes the first magnet 41 and the second magnet 42 repel each other, thereby driving the push rod assembly 3 away from the discharge channel 22 to open the discharge channel 22. The repulsion between the first magnet 41 and the second magnet 42 can effectively keep the discharge channel 22 open, ensuring that the food stored in the hopper 2 can smoothly pass through the discharge channel 22 into the heating cavity 11.
[0031] Optionally, the hopper 2 and the cup cover 1 can be two independent components, and the hopper 2 is assembled on the cup cover 1. Optionally, the upper end of the cup cover 1 is provided with an assembly opening, and the hopper 2 is connected with the assembly opening in a matching manner, so that the storage cavity 21 and the heating cavity 11 are in communication when the discharge channel 22 is in an open state. Optionally, the hopper 2 and the cup cover 1 are integrally formed, which can improve the connection strength of the hopper 2 and the cup cover 1 and simplify the assembly between components.
[0032] Optionally, the first magnet 41 and the second magnet 42 can both be permanent magnets. When the air pressure of the heating cavity 11 drives the push rod assembly 3 to move the second magnet 42 away from the discharge channel 22 to change the distance between the first magnet 41 and the second magnet 42, the first magnet 41 and the second magnet 42 repel each other under the mutual influence of the magnetic field of the first magnet 41 and the magnetic field of the second magnet 42.
[0033] Optionally, one or both of the first magnet 41 and the second magnet 42 is an electromagnet. When the displacement of the second magnet 42 and / or the push rod assembly 3 meets a preset value, a switch can be triggered to start energizing the electromagnet, so that the first magnet 41 and the second magnet 42 repel each other.
[0034] Optionally, one or both of the first magnet 41 and the second magnet 42 is an electromagnet. When the displacement of the second magnet 42 and / or the push rod assembly 3 meets a preset value, a switch can be triggered to change the current direction of at least one electromagnet, so that the first magnet 41 and the second magnet 42 repel each other.
[0035] Referring to Figure 3 , Figure 4 , Figure 5 and Figure 6In some embodiments, the second magnet 42 is assembled at the end of the push rod assembly 3 or the middle of the push rod assembly 3. When the push rod assembly 3 is driven to move by the air pressure change generated by the heating cavity 11 during heating, the magnetic field of the first magnet 41 and the magnetic field of the second magnet 42 interact with each other, so that the first magnet 41 and the second magnet 42 repel each other. Preferably, the push rod assembly 3 comprises a push rod body 31, and the second magnet 42 is assembled at the lower end of the push rod body 31. The lower end of the push rod body 31 is connected to the discharge channel 22. In this way, when the discharge channel 22 is opened, the repulsive force between the first magnet 41 and the second magnet 42 can be effectively reduced, and the stroke of the push rod body 31 driven by the second magnet 42 is ensured. The repulsive force between the first magnet 41 and the second magnet 42 can effectively drive the push rod assembly 3 to move away from the discharge channel 22 to achieve the opening of the discharge. Optionally, the push rod assembly 3 further comprises a push rod sealing sleeve 32, and the push rod body 31 is arranged in the push rod sealing sleeve 32. The second magnet 42 is assembled between the lower end of the push rod body 31 and the push rod sealing sleeve 32. In this way, the second magnet 42 can be wrapped at the lower end of the push rod body 31 by the push rod sealing sleeve 32 to prevent external liquid from corroding the second magnet 42. Further, the push rod sealing sleeve 32 can be further sleeved with a sealing sleeve to improve the sealing performance of the push rod assembly 3 used in the discharge channel 22. At the same time, the sealing sleeve can avoid the mutual friction between the push rod sealing sleeve 32 and the discharge channel 22.
[0036] Specifically, in the initial state, the push rod body 31 is connected to the discharge channel 22, and specifically, the push rod sealing sleeve 32 abuts between the push rod body 31 and the inner wall of the discharge channel 22, so that the push rod assembly 3 blocks the discharge channel 22. Further, the push rod sealing sleeve 32 is provided with a sealing sleeve, so that the push rod sealing sleeve 32 abuts with the discharge channel 22 through the sealing sleeve, drives the push rod assembly 3 and the discharge channel 22 to form a good sealing connection, and improves the sealing effect between the push rod assembly 3 and the discharge channel 22. In this way, when the heating cavity 11 is heated, the internal pressure of the heating cavity 11 can be increased to drive the push rod body 31 to move away from the discharge channel 22, and at the same time, the second magnet 42 is driven by the push rod body 31 to move away from the discharge channel 22, so as to change the distance between the first magnet 41 and the second magnet 42, so that the first magnet 41 and the second magnet 42 repel each other, thereby driving the push rod assembly 3 to move away from the discharge channel 22, so as to open the discharge channel 22, and the repulsive force between the first magnet 41 and the second magnet 42 can effectively keep the discharge channel 22 open, ensuring that the food stored in the hopper 2 can smoothly pass through the discharge channel 22 into the heating cavity 11.
[0037] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , in some embodiments, the storage cavity 21 is located above the heating cavity 11, and when the internal pressure of the heating cavity 11 changes, the internal pressure of the heating cavity 11 can drive the push rod body 31 to move upward. Optionally, the inner diameter of the storage cavity 21 is arranged to increase away from the heating cavity 11, so that the inner wall of the storage cavity 21 is arranged in an arc shape or an inclined manner, which can effectively guide the food stored in the storage cavity 21, and guide the food to automatically fall into the discharge channel 22 under the influence of gravity when the discharge channel 22 is in the open state, and enter the heating cavity 11 through the discharge channel 22.
[0038] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6In some embodiments, the upper end of the hopper 2 is provided with an opening which is in communication with the storage cavity 21, and a top cover 5 is arranged on the opening. In this way, food materials can be loaded into the storage cavity 21 through the opening. After the device is completed, the top cover 5 is closed on the opening to seal the storage cavity 21, so as to prevent the food materials stored in the storage cavity 21 from being disturbed or contaminated by the outside. Further, the top cover 5 is provided with a movable channel 51, and the upper end of the push rod assembly 3 is movably arranged in the movable channel 51. Optionally, the movable channel 51 extends in a direction away from the discharge channel 22. In this embodiment, the movable channel 51 extends in the height direction, and the upper end of the push rod body 31 is movably arranged in the movable channel 51. When the internal air pressure of the heating cavity 11 changes, the internal air pressure of the heating cavity 11 pushes the push rod body 31 to move upward. At the same time, the movable channel 51 can guide the push rod body 31 to move in the height direction, so as to ensure that the internal air pressure of the heating cavity 11 can push the push rod body 31 to move upward, so as to change the distance between the first magnet 41 and the second magnet 42, and further trigger the mutual repulsion between the first magnet 41 and the second magnet 42.
[0039] Referring to Figure 3 , Figure 4 , Figure 5 and 6 In some embodiments, the first magnet 41 is sleeved on the outer periphery of the discharge channel 22, that is, the first magnet 41 has a ring structure. Optionally, the hopper 2 is provided with an assembly groove which surrounds the outer periphery of the discharge channel 22, and the first magnet 41 is assembled in the assembly groove. Optionally, a pressing piece can also be assembled in the assembly groove, and the pressing piece is located above the first magnet 41. In this way, the first magnet 41 can be fixed in the assembly groove by using the pressing piece. Optionally, the outer periphery of the push rod body 31 is provided with a protruding portion. When the push rod body 31 is connected to the discharge channel 22, the protruding portion abuts against the upper end of the pressing piece, so as to further fix the first magnet 41 and prevent the first magnet 41 from moving.
[0040] Preferably, when the distance between the first magnet 41 and the second magnet 42 is L1, the first magnet 41 and the second magnet 42 attract each other, which hinders the movement of the push rod assembly 3, so as to block the discharge channel 22.
[0041] Optionally, when the displacement of the second magnet 42 and / or the push rod assembly 3 meets the preset value L1, the energization of the first magnet 41 and / or the second magnet 42 is started to make the first magnet 41 and the second magnet 42 attract each other. Optionally, when the displacement of the second magnet 42 and / or the push rod assembly 3 meets the preset value L1, the current direction of the first magnet 41 and / or the second magnet 42 is changed to make the first magnet 41 and the second magnet 42 attract each other. In the embodiment, the magnetic field direction of the first magnet 41 is opposite to that of the second magnet 42, and the first magnet 41 is in a ring structure. Therefore, when the distance between the first magnet 41 and the second magnet 42 is L1, the magnetic field of the first magnet 41 and the magnetic field of the second magnet 42 attract each other, that is, the first magnet 41 and the second magnet 42 attract each other, effectively preventing the movement of the push rod assembly 3, ensuring that the push rod body 31 blocks the discharge channel 22, preventing the food materials in the storage bin 2 from leaking into the heating cavity 11. Optionally, the L1 can be a specific value, and optionally, the L1 can be a certain value range. Further, when the heating cavity 11 is heated, the internal pressure in the heating cavity 11 increases, and when F 气 >(F 吸 +F 杆 +F 摩 ), the internal pressure in the heating cavity 11 can drive the push rod assembly 3 to move the second magnet 42 away from the discharge channel 22, changing the distance between the first magnet 41 and the second magnet 42, wherein F 气 is the force formed by the pressure in the heating cavity 11, F 吸 is the attractive force between the first magnet 41 and the second magnet 42, F 杆 is the gravity of the push rod assembly 3, and F 摩 is the friction between the push rod assembly 3 and the discharge channel 22. Preferably, L1 preferably meets: 4mm≦L1≦8mm;
[0042] Preferably, when the distance between the first magnet 41 and the second magnet 42 is L2, the first magnet 41 and the second magnet 42 repel each other, driving the push rod assembly 3 away from the discharge channel 22 to open the discharge channel 22. Optionally, the L2 can be a specific value, and optionally, the L2 can be a certain value range.
[0043] Optionally, when the displacement of the second magnet 42 and / or the push rod assembly 3 meets the preset value L2, the energization of the first magnet 41 and / or the second magnet 42 is started to make the first magnet 41 and the second magnet 42 repel each other, which can be determined by a position sensor or the like. Figure 7 In the embodiment, when the distance between the first magnet 41 and the second magnet 42 is L2, the magnetic field of the first magnet 41 and the magnetic field of the second magnet 42 repel each other because the magnetic field direction of the first magnet 41 is opposite to the magnetic field direction of the second magnet 42, that is, the first magnet 41 and the second magnet 42 repel each other, and the overall force condition at this time is: (F 气 +F 斥 )>(F 杆 +F 摩 ), wherein F 斥 is the repulsion between the first magnet 41 and the second magnet 42, that is, the force formed by the gas pressure in the heating cavity 11 and the repulsion between the first magnet 41 and the second magnet 42 jointly drive the push rod assembly 3 to move the second magnet 42 away from the discharge channel 22, when the push rod assembly 3 leaves the discharge channel 22, the gas pressure in the heating cavity 11 is relieved, at this time F 斥 >F 杆 , or F 斥 >(F 杆 +F 摩2 ), wherein F 摩2 is the friction between the movable channel 51 and the push rod assembly 3, that is, the repulsion between the first magnet 41 and the second magnet 42 can continue to drive the push rod assembly 3 to move the second magnet 42 away from the discharge channel 22, and can effectively keep the discharge channel 22 open, ensuring that the food stored in the hopper 2 can smoothly pass through the discharge channel 22 into the heating cavity 11. Preferably, L2 preferably satisfies: 6mm≦L2≦10mm.
[0044] In some embodiments, the second magnet 42 can be of any shape, preferably, the second magnet 42 is ring-shaped or circular, preferably, the inner diameter of the first magnet 41 is greater than the diameter of the second magnet 42. Preferably, 60% D1≦D2≦80% D1, wherein D1 is the inner diameter of the first magnet 41, and D2 is the diameter of the second magnet 42. In the present embodiment, the relationship between the inner diameter of the first magnet 41 and the diameter of the second magnet 42 satisfies: 60% D1≦D2≦80% D1, the magnetic field direction of the first magnet 41 is opposite to that of the second magnet 42, and the first magnet 41 is ring-shaped, so when the distance between the first magnet 41 and the second magnet 42 is L1, the magnetic field of the first magnet 41 and the magnetic field of the second magnet 42 attract each other, when the distance between the first magnet 41 and the second magnet 42 is L2, because the magnetic field direction of the first magnet 41 is opposite to that of the second magnet 42, at this time the magnetic field of the first magnet 41 and the magnetic field of the second magnet 42 repel each other, that is, the mutual attraction or repulsion between the first magnet 41 and the second magnet 42 can be changed by changing the distance between the first magnet 41 and the second magnet 42.

Optionally, the cooking device includes, but is not limited to, a blender, a soybean milk machine, a food processor, an electric rice cooker, an electric rice cooker, an electric boiling pot, a soup pot, and a stew pot.
[0046] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , in some embodiments, in the initial state, the push rod body 31 is connected to the discharge channel 22 to block the discharge channel 22, driving the discharge channel 22 to be in a closed state, at this time the distance between the first magnet 41 and the second magnet 42 is L1, because the magnetic field direction of the first magnet 41 is opposite to that of the second magnet 42, the first magnet 41 is ring-shaped, and the inner diameter of the first magnet 41 is greater than the diameter of the second magnet 42, at this time the magnetic field of the first magnet 41 and the magnetic field of the second magnet 42 attract each other, that is, the first magnet 41 and the second magnet 42 attract each other, effectively preventing the movement of the push rod assembly 3, ensuring that the push rod body 31 blocks the discharge channel 22, preventing the food materials in the storage bin 2 from leaking into the heating cavity 11, further, when the heating cavity 11 is heated, the air pressure in the heating cavity 11 increases, when F 气 > (F 吸 +F 杆 +F摩 ) the internal air pressure in the heating cavity 11 can drive the push rod assembly 3 to move the second magnet 42 away from the discharge channel 22, changing the distance between the first magnet 41 and the second magnet 42, and at the same time F 吸 As the distance between the first magnet 41 and the second magnet 42 increases, the magnetic field of the first magnet 41 and the magnetic field of the second magnet 42 repel each other, that is, the first magnet 41 and the second magnet 42 repel each other, so at this time the overall force condition is: (F 气 +F 斥 ) > (F 杆 +F 摩 ), where F 斥 is the repulsive force between the first magnet 41 and the second magnet 42, that is, the force formed by the air pressure in the heating cavity 11 and the repulsive force between the first magnet 41 and the second magnet 42 together drive the push rod assembly 3 to move the second magnet 42 away from the discharge channel 22, and F 斥 As the distance between the first magnet 41 and the second magnet 42 increases, the air pressure in the heating cavity 11 is released after the push rod assembly 3 leaves the discharge channel 22, at this time F 斥 > F 杆 , or F 斥 > (F 杆 +F 摩2 ), where F 摩2 is the friction between the movable channel 51 and the push rod assembly 3, that is, the repulsive force between the first magnet 41 and the second magnet 42 can continue to drive the push rod assembly 3 to move the second magnet 42 away from the discharge channel 22, and can effectively keep the discharge channel 22 open, ensuring that the food stored in the hopper 2 can smoothly pass through the discharge channel 22 into the heating cavity 11.
