[0050] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0051] Currently, most intelligent cooking devices guide users to manually add salt, MSG, and other seasonings to the pot via images, text, or videos. This makes the cooking process less intelligent, requiring users to expend considerable time and effort. Furthermore, manual addition of seasonings can lead to inaccurate results and poor flavor. While some existing technologies offer automatic seasoning addition, these suffer from cumbersome process and potential flavor mixing issues between different seasonings.

[0052] To address the aforementioned problems, embodiments of this application provide a control method, a feeding method, a feeding device, and a cooking apparatus including a feeding device. Utilizing the technical solutions provided by the embodiments of this application, automatic seasoning addition can be achieved while allowing for the separate addition of different types of seasonings, ensuring that different seasonings do not cross-contaminate in flavor. To enable those skilled in the art to better understand the solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Before introducing the method embodiments provided by this application, a brief description will be given of the hardware devices required to implement the methods provided by this application.

[0053] The hardware device required to implement the method provided in this application is a specially designed hardware device serving a specific field, such as the feeding device or cooking equipment including a feeding device provided in this application. For details, please refer to [link to relevant documentation]. Figures 1a to 3 As shown:

[0054] In some embodiments of this application, a cooking device is provided, including a main body 2000 and a feeding device 1000, the feeding device 1000 including a feeding unit 100. The main body 2000 has a cooking container 201 for holding ingredients and, in conjunction with other functional components on the main body, for cooking the ingredients. The feeding device 1000 is used to hold seasonings, and the feeding unit 100 is used to deliver seasonings into the cooking container to flavor the ingredients in the cooking container 201.

[0055] In some embodiments of this application, the cooking equipment includes, but is not limited to, cooking appliances such as stir-fry machines, food processors, and stand mixers. Figure 1aThe illustration shows a cooking device that is a stir-fry machine. Accordingly, the main body 2000 may also include an operating platform 202, on which the cooking container 201 is mounted, providing support for the cooking container. Furthermore, other functional components may be provided on the main body, such as a heating element on the main body 2000 to provide a heat source for the cooking container 201, heating the food inside. Support legs may also be provided at the bottom of the main body 2000 to support its bottom surface, creating a gap between it and the tabletop for heat dissipation. In addition, a display area may be provided on the main body 2000 for users to operate and control the cooking device, displaying operating steps, cooking process parameters, etc. Furthermore, the main body 2000 may also include an operating area, which may be integrated with the display area, allowing users to operate and control the cooking device, such as inputting human-machine interface control commands. Figure 1a The above examples do not specifically show or indicate other functional components that can be set in the host unit.

[0056] In some embodiments, the main unit 2000 is electrically connected to the feeding device 1000 so that the main unit 2000 can supply power to the feeding device 1000. The main unit 2000 may have a built-in power supply, or the main unit 2000 may have a power cord for connection to an external power source. In a specific implementation, in one particular example, the main unit 2000 may be provided with a first electrical interface 2021. The first electrical interface 2021 and the second electrical interface 117 on the feeding device 1000 are wiredly connected via a power cord P, so that power is supplied to the feeding device 1000 through the second electrical interface 117, thereby enabling the main unit 2000 to provide power to the feeding device 1000. In some embodiments, the feeding device 1000 and the main unit 2000 may also be wirelessly connected, as long as the feeding device 1000 can be powered through the main unit 2000. Of course, in some other embodiments, power can be supplied to the feeding device 1000 without the main body 2000. For example, a power plug adapted to the feeding device 1000 can be connected to an external power source to supply power to the feeding device 1000; wherein, one end of the power plug is electrically connected to an external power source (such as AC mains) to supply power, and the other end is electrically connected to the second electrical interface 117 of the feeding device 1000 to supply power to the feeding device 1000. This embodiment is not limited to the specific implementation of supplying power to the feeding device 1000. Figure 1a The diagram shows the power supply to the feeding device 1000 via the main body 2000.

[0057] The feeding device 1000 and the main unit 2000 can be communicatively connected to enable data transmission between them. Specifically, the communication between the main unit 2000 and the feeding device 1000 is wireless communication. This wireless communication method can be, but is not limited to, short-range communication methods such as Bluetooth, ZigBee, infrared, and WiFi (Wireless Fidelity), as well as long-range wireless communication methods such as LoRa, and mobile network-based wireless communication methods. When communicating via a mobile network, the network standard can be, but is not limited to, any one of 2G (GSM), 2.5G (GPRS), 3G (WCDMA, TD-SCDMA, UTMS), 4G (LTE), 4G+ (LTE+), 5G, and WiMax. In this embodiment, Bluetooth is selected as the preferred communication method between the main unit 2000 and the feeding device 1000. Therefore, in some application scenarios, users can select or set the current operation step by operating the display area on the main unit 2000, and this operation step includes the ingredient addition step. The main unit 2000 transmits the ingredient addition step selected by the user to the ingredient addition device 1000, which can then perform the ingredient addition operation according to the step. This enables automatic ingredient addition and improves the automation level of the cooking equipment.

[0058] In some embodiments, the main body 2000 includes an operation module (i.e., the aforementioned operation area), and the feeding device 1000 includes a controller. When the main body 2000 and the feeding device 1000 establish a communication connection, the controller of the feeding device 1000 can obtain relevant information about the target seasoning to be added, input by the operation module, and control the feeding device 1000 to perform relevant operations based on the relevant information. The cooking device in this embodiment also includes a conveying assembly 80, which connects the main body 2000 and the feeding device 1000, enabling the feeding device 1000 to convey seasoning to the cooking container 201 of the main body 2000 via the conveying assembly 80. Figure 1c and Figure 1d As shown, in order to facilitate the assembly and storage of the cooking equipment, the feeding assembly 80 can be detachably connected to the main body 2000 and the feeding device 1000 respectively, so that the feeding assembly 80, the main body 2000 and the feeding device 1000 can be stored separately.

[0059] In some embodiments, see Figure 1eAs shown, the material conveying assembly 80 is connected to the main body 2000 and / or the feeding device 1000 via a locking assembly 90; wherein the locking assembly 90 includes a locking part 91 and a force-applying part 92. The locking part 91 is movable between a locking position and a releasing position. In the locking position, the main body 2000 and / or the feeding device 1000 are connected to the material conveying assembly 80; in the releasing position, the material conveying assembly 80 is separated from the main body 2000 and / or the feeding device 1000. The material conveying assembly 80 and the main body 2000, as well as the material conveying assembly 80 and the feeding device 1000, can be connected via the locking assembly 90 to achieve a detachable connection between the material conveying assembly 80 and the main body 2000, and between the material conveying assembly 80 and the feeding device 1000.

[0060] The force-applying part 92 is connected to the locking part 91 and is used to receive external force to drive the locking part 91 from the locking position to the release position. For example, the force-applying part 92 can be used to receive pressure applied by the user, causing the locking part 91 to disengage from the locking position, thereby allowing the material conveying assembly 80 to separate from the main body 2000 or the feeding device 1000 connected to it, achieving disassembly. In other embodiments, the force applied by the force-applying part 92 can also be rotational torque, push-pull force, etc. Through reasonable structural design, the locking part 91 can disengage from the locking position under a preset force. This application does not limit the specific driving method.

[0061] In some embodiments, the locking assembly 90 further includes an elastic portion 93. The elastic portion 93 is connected to the latching portion 91. The force-applying portion 92 can receive an external force to cause the elastic portion 93 to elastically deform, and the latching portion 91 moves from the latching position to the released position. When the external force is removed, the elastic portion 93 returns to its original deformation, and the latching portion 91 returns from the released position to the latching position. For example, the elastic portion 93 can be a compression spring, and the two ends of the compression spring can be connected to the force-applying portion 92 and the latching portion 91, respectively. Thus, the force applied to the force-applying portion 92 can act on the elastic portion 93, causing the elastic portion 93 to deform. When the force-applying portion 92 is not subjected to external force, the elastic portion 93 can be in a natural state or a state of small deformation. During the process of removing the external force, the elastic portion 93 gradually returns to its original deformation, causing the force-applying portion 92 and the latching portion 91 to return to their initial state, and the latching portion 91 returns to the latching position.

[0062] In a specific application scenario, when it is necessary to connect the feeding assembly 80 to the main body 2000, the user presses the force-applying part 92, the locking part 91 moves to the preset release position, and then inserts the feeding assembly 80 into the preset connection position on the main body 2000. Releasing the force-applying part 92, the locking part 91 moves to the locking position with the main body 2000 under the restoring force of the elastic part 93, thus reliably connecting and locking the feeding assembly 80 to the main body 2000. Therefore, during the entire use of the cooking equipment, the feeding assembly 80 is less likely to be accidentally touched, causing the connection between it and the main body 2000 to loosen.

[0063] Of course, the connection method between the material conveying component 80 and the feeding device 1000 can refer to the connection method between the material conveying component 80 and the main body 2000, and will not be elaborated here.

[0064] The material conveying assembly 80 includes a material conveying pipe 81 and a connecting joint 82. The connecting joint 82 is located at the end of the material conveying pipe 81, and a locking component 90 is disposed on the connecting joint 82. The main body 2000 and / or the feeding device 1000 are provided with an insertion portion (not shown in the figures) for at least a portion of the connecting joint 82 to be inserted. Specifically, the insertion portion can be a recess or a groove. The connecting joint 82 can be fixedly connected to the material conveying pipe 81. By inserting the connecting joint 82 into the insertion portion of the main body 2000 or the feeding device 1000, the contact area at the connection between the material conveying assembly 80 and the main body 2000 or the feeding device 1000 is larger, making the connection more stable and reliable. Specifically, the connecting joint 82 includes a first connector portion 82a and a second connector portion 82b. The first connector portion 82a is connected to the material conveying pipe 81. The second connector 82b is partially inserted into and fixed within the first connector 82a, and the other part is used to connect with the feeding device 1000 and / or the main body 2000 via the locking component 90. The locking component 90 is located between the first connector 82a and the second connector 82b, and the snap-fit ​​portion 91 of the locking component 90 is used to extend from the second connector 82b to snap-fit ​​with the feeding device 1000 and / or the main body 2000.

[0065] The connector 82 is designed as a split structure, with the locking component 90 housed within the split connector 82. This facilitates the molding of the connector 82 and the installation of the locking component 90. More specifically, the first connector portion 82a may have a through hole 82a1 for the force-applying portion 92 to protrude. After the first connector portion 82a and the second connector portion 82b are molded separately, the locking component 90 can be connected to the first connector portion 82a, and then the locking component 90 and the entire first connector portion can be inserted into the second connector portion 82b to form a single unit. This makes the molding and assembly of the connector 82 more convenient.

[0066] Some embodiments of this application also provide another cooking device, including: a main body 2000 and a feeding device 1000. The feeding device 1000 is used to hold seasonings; the feeding device 1000 is communicatively connected to the main body 2000 to enable data transmission between the feeding device 1000 and the main body 2000. A conveying assembly 80 connects the main body 2000 and the feeding device 1000, and the conveying assembly 80 is used to convey the seasonings in the feeding device 1000 to the cooking container of the main body 2000. This embodiment is basically the same as the above embodiments, except that this embodiment does not limit the electrical connection between the feeding device 1000 and the main body 2000. They can be connected to different power sources, as long as the feeding device 1000 and the main body 2000 are communicatively connected and the seasonings are conveyed through the conveying assembly 80, thereby facilitating the autonomous feeding of the cooking device.

[0067] Please refer to the reference. Figure 2 , Figure 6 and Figure 8a and Figure 8b In some embodiments, the feeding unit 100 includes a bottle assembly 10, which includes a plurality of bottles 11, each of which has a discharge port 111 (see discharge port 111 for details). Figure 6 ),by Figure 2 Taking the direction of the container as an example, the outlet 111 is located at the bottom of the container 11, allowing the seasonings inside the container 11 to be drawn into the cooking container. Different containers 11 can hold different seasonings, including liquid mixed seasonings, oil, water, etc. The mixed seasonings include at least one liquid mixture such as salt, ginger, garlic, light soy sauce, dark soy sauce, and chili. Multiple containers 11 can be used to separate various seasonings to meet different needs.

[0068] Because some seasonings are used frequently or in large quantities at a time, while others are used infrequently or in small quantities, in order to make more efficient use of the seasoning bottles 11, in one embodiment, at least two types of seasoning bottles 11 have different capacities. Specifically, among the multiple seasoning bottles 11, at least one seasoning bottle 11 has a first capacity, and at least one seasoning bottle 11 has a second capacity, wherein the first capacity is greater than the second capacity. Figure 2 and Figure 8aTaking the five containers 11 shown as an example, three of them are the same size and have a third capacity, while the other two are of different sizes, having a first capacity and a second capacity respectively, with the third capacity being smaller than the second capacity. In other words, the five containers 11 are divided into three sizes: large, medium, and small, with three small containers 11. Typically, the large first-capacity container 11 is used to hold frequently used and large-volume seasonings, such as water, for self-cleaning of cooking equipment, as the equipment needs cleaning almost every time you cook. The small third-capacity container 11 is used to hold infrequently used and small-volume seasonings, such as salt, ginger, garlic, light soy sauce, dark soy sauce, chili peppers, sugar, etc., in combination. The medium-sized second-capacity container 11 holds cooking oil. In one embodiment, the three small containers 11 hold the combination of seasonings. Furthermore, for ease of addition, solid seasonings such as ginger, garlic, and chili peppers can be ground into powder, mixed with water to form a combination, and then placed in the small containers 11. Three small seasoning bottles 11 can hold different proportions of mixed seasonings to create different flavors, such as original, spicy, and sweet. For easier assembly, each seasoning bottle 11 has a similar shape and the same height, ranging from 100mm to 350mm, preferably 216mm. This ensures that the entire assembly can be joined into a single structure with a uniform height. "Similar shape" here refers to the identical cross-sectional shape of each seasoning bottle 11.

[0069] In some embodiments, each bottle 11 has a fan-shaped cross-section so that multiple bottles 11 can be assembled into a bottle assembly 10 with a circular cross-section. The turntable 20 has multiple partitioned cavities 21 (e.g., Figure 3 and Figure 9 Each partition cavity 21 is used to accommodate one material bottle 11, and the cross-sectional shape of each partition cavity 21 matches the cross-sectional shape of the corresponding material bottle 11 so that multiple partition cavities 21 are assembled into a circle.

[0070] Each bottle 11 has a fan-shaped cross-section with a different central angle, thus achieving different capacities. For example, such as... Figure 2 , Figure 3 and Figure 8aAs shown, the central angle of the first-capacity bottle 11 is larger than that of the second-capacity bottle 11, and the central angle of the second-capacity bottle 11 is larger than that of the third-capacity bottle 11. In some embodiments, the central angle of the first-capacity bottle 11 ranges from 90 degrees to 180 degrees, the central angle of the second-capacity bottle 11 ranges from 60 degrees to 120 degrees, and the central angle of the third-capacity bottle 11 ranges from 30 degrees to 60 degrees. As a preferred embodiment, the central angle of the first-capacity bottle 11 is 135 degrees, the central angle of the second-capacity bottle is 90 degrees, and the central angle of the third-capacity bottle 11 ranges from 45 degrees, with the central angles of the five bottles forming 360 degrees. In other embodiments, the shapes of some of the bottles 11 may also be different. Designing the bottle assembly 10 as circular and cooperating with the circular turntable 20 can result in a smaller overall volume, more efficient use of space, less kitchen area occupied, and a better user experience.

[0071] In some embodiments, the first-capacity container 11 is filled with water. During the operation of the cooking equipment, the amount of water used is relatively large. To ensure that the container assembly 10 has a sufficient volume of water without affecting the overall diameter and height of the container assembly, and to achieve a reasonable and balanced overall layout of the container assembly 10 and the multiple containers 11, the volume of the first-capacity container 11 is at least greater than or equal to 1 liter. To enable the addition of seasonings into the container 11, in some embodiments, such as... Figures 8a to 8c As shown, the container 11 includes a container body 114 and a cap 115. The container body 114 can be open, and the cap 115 covers the open end of the container body 114. The cap 115 and the container body 114 are separable. The cap 115 detachably seals the open end of the container body 114, allowing the cap 115 to be opened and the condiment to be added to the container body 114 when the condiment is insufficient. Furthermore, as... Figure 8bAs shown, a vent 1151 is provided on the cap 115, which communicates with the interior of the bottle 114. This ensures that the air pressure inside and outside the bottle 11 can be balanced when the outlet 111 and the inlet 22 are connected for material intake. Furthermore, a check valve 1152 is provided at the vent 1151. The check valve 1152 allows external air to enter the bottle 114 while preventing liquid from flowing out of the bottle 114. Specifically, the check valve 1152 can be a duckbill type check valve, which allows air to pass through but prevents liquid from flowing out. Therefore, even if the bottle 11 is inverted, the liquid seasoning inside the bottle 114 will not leak out. In some embodiments, the vent 1151 is normally open, and the check valve 1152 is normally closed. When some of the seasoning in the bottle 11 flows to the main body 2000, the air pressure inside the bottle 11 decreases. Under atmospheric pressure, the check valve 1152 opens in one direction, allowing outside air to enter the bottle 11 through the vent 1151 and the check valve 1152 to maintain air pressure balance inside and outside the bottle 11. The check valve 1152 is a flexible one-way valve to ensure that the seasoning in the bottle 11 flows smoothly into the main body 2000.

[0072] In some embodiments, such as Figure 8b The cap 115 may include a first part 115a and a second part 115b that interlock with each other. The second part 115b covers the bottle body 114, and the first part 115a covers the second part 115b. The first part 115a and the second part 115b, when interlocked, form a receiving cavity. A check valve 1152 may be disposed on the second part 115b, specifically embedded therein. The check valve 1152 may be located within the receiving cavity. One end of the check valve 1152 communicates with a vent 1151, and the other end extends through the second part 115b into the interior of the bottle body 114. In some embodiments, at least a portion of the check valve 1152 is located between the first part 115a and the second part 115b, and at least a portion of the check valve 1152 is located inside the bottle body 114. A vent 1151 and a check valve 1152 are provided to facilitate the disassembly and assembly of the cap 115 and to ensure the smooth flow of the seasoning in the bottle 11 into the main body. In some embodiments, both the cap 115 and the bottle 114 have a fan-shaped cross-section, with the vent 1151 and check valve 1152 positioned at the center of the fan-shaped area. It is understood that, to facilitate the replacement of the check valve 1152, the first part 115a and the second part 115b can be detachably connected, for example, by snap-fit ​​or by interference fit with a sealing ring. When the external force exceeds the snap-fit ​​force or interference fit force, the first part 115a and the second part 115b can be separated. Preferably, the first part 115a and the second part 115b can be detachably and sealingly connected so that, in the assembled state, air in the bottle 114 can only be discharged through the check valve 1152.

[0073] Please refer to the reference. Figure 2 , Figure 3 and Figure 9 To better accommodate multiple bottles 11 into a single unit, in some embodiments, the feeding unit 100 further includes a turntable 20. The bottle assembly 10 is mounted to the turntable 20, forming a single unit with it, thereby preventing the multiple bottles 11 from scattering. One possible installation method for the bottle assembly 10 and the turntable 20 is that the turntable 20 has multiple partitioned cavities 21, and each partitioned cavity 21 has a feeding port 22 on its bottom wall. That is, if... Figure 10a The shown from Figure 9 The diagram shows a three-dimensional view of the turntable 20 from another angle (i.e., the angle of the bottom surface of the turntable), and... Figure 10b The simplified top view of the turntable 20 shown is from another angle. The turntable 20 has multiple feeding ports 22, for example, Figure 10b The filling ports 222, 221b, 221c, 221d, and 221e are shown in the diagram. Each of the aforementioned partition chambers 21 can accommodate a container of seasoning 11. When a container of seasoning 11 is inserted into a corresponding partition chamber 21, the outlet 111 at the bottom of the container 11 will align with the filling port 22 of the partition chamber 21 to dispense seasoning into the cooking container. For a description of the alignment, please refer to the relevant content below; it will not be repeated here.

[0074] Figure 9 , Figure 10a and Figure 10b This shows a turntable 20 with 5 feeding ports. Figure 10b The document also shows the positional relationship of each feeding port; this relationship is determined based on a reference position, which can be found in the following description. Additionally, Figure 9 , Figure 10a and Figure 10b The number of feeding ports and their positional relationships shown are merely illustrative and do not limit the number of feeding ports or their positional relationships. In this embodiment, by dividing the turntable 20 into multiple partitioned cavities 21, each bottle 11 can be inserted into a corresponding partitioned cavity 21, allowing the user to remove any bottle 11 as needed. Simultaneously, since each bottle 11 is in contact with a partitioned cavity 21 on all four sides, the limiting effect on a single bottle 11 is better, effectively preventing the bottle 11 from becoming detached from the partitioned cavity 21. Compared to inserting all bottle assemblies 10 into a single cavity, the partitioning method of the turntable 20 in this embodiment offers greater flexibility.

[0075] The insertion method includes a tight fit, i.e., an interference fit or a transition fit between the bottle 11 and the partition cavity 21, where the side of the bottle 11 is in close contact with the cavity wall of the partition cavity 21 to prevent them from separating. The insertion method also includes a clearance fit to facilitate the removal of the bottle 11. In a clearance fit, to prevent the bottle 11 from loosening from the turntable 20, one possible method is to use a snap-fit ​​structure between the bottle 11 and the turntable 20 for engagement. The insertion method facilitates the installation and separation of the bottle 11 and the turntable 20, making it easy to remove the bottle 11. The insertion method includes, but is not limited to, partially inserting the bottle 11 into the partition cavity 21; for example, the bottom of the bottle 11 is inserted into the partition cavity 21, while the middle and top are exposed outside the partition cavity 21. Of course, in other embodiments, the bottle 11 can also be entirely located within the partition cavity 21. To improve the structural strength of the turntable 20, in some embodiments, such as... Figure 9 As shown, the cavity wall of the partition cavity 21 is provided with at least one reinforcing rib 23. The reinforcing rib 23 extends from the bottom wall of the partition cavity 21 toward the opening of the partition cavity 21. In this way, when the bottle 11 is inserted, the reinforcing rib 23 can prevent the bottle 11 from squeezing and deforming the partition cavity 21. For example, one possible way for the bottle 11 and the reinforcing rib 23 to cooperate is that the side wall of the bottle 11 contacts the reinforcing rib 23. When multiple reinforcing ribs 23 are provided around the same partition cavity 21, the reinforcing ribs 23 separate the side wall of the bottle 11 from the cavity wall of the partition cavity 21, while the side wall of the bottle 11 abuts against the reinforcing rib 23. This reduces the contact area between the bottle 11 and the cavity wall of the partition cavity 21, reducing the friction and resistance between them, and facilitating the quick insertion or removal of the bottle 11. In addition, the reinforcing rib 23 can also restrict the rotation of the bottle 11 relative to the turntable 20.

[0076] In some embodiments, another possible way to cooperate between the bottle 11 and the reinforcing rib 23 is that a slot is provided on the side wall of the bottle 11, and the reinforcing rib 23 is inserted into the slot. In this way, the reinforcing rib 23 has the effect of positioning the bottle 11, preventing the bottle 11 from deviating from its position, and the reinforcing rib 23 also restricts the rotation of the bottle 11 relative to the turntable 20. Another possible way to install the bottle assembly 10 and the turntable 20 is that a buckle is provided on the turntable 20, and the bottle assembly 10 is provided with a slot to engage with the buckle. Of course, in other embodiments, the bottle assembly 10 and the turntable 20 can also be fixed by magnetic attraction. In order to output the seasoning to the cooking container, in this embodiment, the turntable 20 is provided with a feeding port 22, and the dispensing port 111 of the bottle 11 is aligned with the feeding port 22 to output the seasoning to the cooking container. In this embodiment, the alignment of the discharge port 111 and the feeding port 22 means that, along the discharge direction of the discharge port 111, the feeding port 22 and the discharge port 111 are completely overlapped or at least partially overlapped, so that the feeding port 22 can receive the seasoning flowing out from the discharge port 111. Taking the up-down direction as an example, the turntable 20 is set below the material bottle 11, the bottom of the material bottle 11 is inserted into the turntable 20, and the feeding port 22 is located directly below the discharge port 111.

[0077] Please refer to the reference. Figure 6 and Figure 8b To prevent the seasoning in the bottle 11 from flowing out during non-preset feeding states, in some embodiments, a one-way valve 112 is provided at the outlet 111 of the bottle 11. This valve is used to open or seal the outlet 111, thereby controlling the outflow of seasoning from the bottle 11 and preventing arbitrary spillage. The cooking device also includes a feed pump, which provides the power to supply the seasoning to the cooking container. When seasoning needs to be added to the cooking container, the feed pump starts, generating negative pressure and opening the one-way valve 112, allowing the seasoning to flow out. For a detailed description of the feed pump, please refer to the following related content. Specifically, please refer to the appendix. Figure 6 and attached Figure 8cThe valve body 1121 of the one-way valve 112 is sealed and fixed to the connecting ring rib 113. In the stationary state, the valve core 1122 of the one-way valve 112 is in a sealed closed position relative to the valve body 1121, thus separating the discharge port 111 from the feed port 22. Under the action of a preset suction force (the negative pressure provided by the feed pump), the valve core 1122 of the one-way valve 112 moves to the open position relative to the valve body 1121, thus connecting the discharge port 111 and the feed port 22. The one-way valve 112 being in a stationary state means that, without suction force, the valve core 1122 is in its initial state. The valve core 1122 includes a plunger 1122a and a spring 1122b connected to the plunger 1122a. The spring 1122b is connected to both the plunger 1122a and the valve body 1121. Under the action of suction force, valve core 1122 can descend and be in the open position, so that the discharge port 111 and the feed port 22 are connected; when valve core 1122 is not under the action of suction force, spring 1122b resets plunger 1122a and rises, and valve core 1122 is in the sealed closed position relative to valve body 1121, so that discharge port 111 and feed port 22 are separated and the flow is cut off.

[0078] In some embodiments, such as Figure 1a , Figure 1b and Figure 4 The feeding unit 100 is rotatable around a rotation axis. Specifically, the turntable 20 of the feeding unit 100 is rotatable around a rotation axis, and multiple partitioned chambers 21 are sequentially distributed around the rotation axis. In this embodiment, the bottle assembly 10 is installed inside the turntable 20, so the bottle assembly 10 and the turntable 20 rotate synchronously. Please refer to the reference again. Figure 8a and Figure 9In some embodiments, the projections of the partition chambers 21 and the containers 11 on the plane are both fan-shaped. Multiple partition chambers 21 are spliced ​​to form a circle, and multiple containers 11 are spliced ​​to form a circle. The multiple partition chambers 21 and multiple containers 11 correspond one-to-one, and the multiple partition chambers 21 and multiple containers 11 are distributed in a circumferential direction with the rotation axis as the center. Multiple feeding ports 22 are also distributed in a circumferential direction with the rotation axis as the center. Each partition chamber 21 is provided with a feeding port 22, and each feeding port 22 is located on the central axis of the bottom wall of the partition chamber 21. The containers 11 and the turntable 20 are made into circles. The use of rotation to switch the types of seasonings can effectively reduce the volume and allow more types of seasonings to be placed in a limited kitchen space. In this embodiment, the rotation axis passes through the center of the turntable 20. Similarly, the rotation axis passes through the center of the spliced ​​circular container assembly 10. In some embodiments, the height of the circular turntable 20 ranges from 10 mm to 60 mm, preferably 35 mm, and the diameter of the circular turntable 20 ranges from 100 mm to 300 mm, preferably 156 mm. To ensure that the bottle 11 is stably inserted into the turntable 20, the height of the turntable is greater than or equal to one-tenth of the height of the bottle.

[0079] In some embodiments, multiple partition cavities 21 are arranged in multiple zones. Each partition cavity 21 includes a first partition cavity 21a, a second partition cavity 21b, and a third partition cavity 21c. The first partition cavity 21a corresponds to a first-capacity bottle 11, the second partition cavity 21b corresponds to a second-capacity bottle 11, and the third partition cavity 21c corresponds to a third-capacity bottle 11. The volume of the first partition cavity 21a is greater than the volume of the second partition cavity 21b, the volume of the second partition cavity 21b is greater than the volume of the third partition cavity 21c, and the three third partition cavities 21c have the same volume. The multiple partition cavities 21 are distributed in a circumferential direction centered on the rotation axis, and the cross-sections of the multiple partition cavities 21 are arranged in a fan shape, forming a circular turntable 20. The central angle of the sector of the first partition cavity 21a ranges from 90 degrees to 180 degrees, preferably 135 degrees; the central angle of the sector of the second partition cavity 21b ranges from 60 degrees to 120 degrees, preferably 90 degrees; the central angle of the sector of the third partition cavity 21c ranges from 30 degrees to 60 degrees, preferably 45 degrees; the central angle of the sector of the first partition cavity 21a is larger than the central angle of the sector of the second partition cavity 21b, the central angle of the sector of the second partition cavity 21b is larger than the central angle of the sector of the third partition cavity 21c, and the central angle of the sector of the three third partition cavities 21c is the same.

[0080] For the bottle assembly 10, at least two bottles 11 have different central angles in their cross-sections, so that at least two bottles 11 have different capacities. The volume of the bottle 11 corresponding to commonly used condiments (such as water, cooking oil, etc.) can be larger than the volume of the bottle 11 corresponding to less commonly used condiments (such as vinegar, cooking wine, light soy sauce, etc.), thereby reducing the number of times the user needs to add condiments. To facilitate the processing and molding of the turntable 20, in one embodiment, the turntable 20 includes a body 24 and a plurality of partitions 25 integrally injection molded with the body 24. The body 24 has an inner cavity, and the plurality of partitions 25 are located in the inner cavity and arranged radially. The space formed by two adjacent partitions 25 and the cavity wall of the inner cavity between two adjacent partitions 25 constitutes a partition cavity 21. In this embodiment, the turntable 20 can be integrally injection molded from plastic material, which can form a relatively complex structure, is simple to process, and is also convenient for mass production. Furthermore, the integral injection molding of the partition 25 and the main body 24 eliminates the need for subsequent assembly processes, saving costs. Simultaneously, the lightweight plastic turntable 20 experiences less load during rotation, facilitating smooth operation. Of course, in other embodiments, the turntable 20 can also be made of other materials, such as metal. Additionally, the partition 25 and the main body 24 can be separate components. For example, a large cavity can be formed within the main body 24, with mounting posts within the cavity. Slots can be provided on the mounting posts and the cavity walls, allowing the two sides of the partition 25 to be inserted into the slots on the mounting posts and the cavity walls, respectively.

[0081] In some embodiments, a foolproof structure is provided between at least one bottle 11 and at least one partition cavity 21. Specifically, at least one bottle 11 has a first foolproof part, and the cavity wall of at least one partition cavity 21 is provided with a second foolproof part that cooperates with the first foolproof part. When the turntable 20 has only two partition cavities 21 and corresponding to only two bottles 11, at least one partition cavity 21 and the corresponding bottle 11 have a foolproof structure, while the other partition cavity 21 and the corresponding bottle 11 do not have a foolproof structure, or have different foolproof structures. By designing a foolproof structure, incorrect installation of the bottle 11 can be avoided. Furthermore, at least two bottles 11 have a first foolproof part, and the cavity walls of at least two partition cavities 21 are provided with a second foolproof part; the positions of each second foolproof part on the fan-shaped shape formed by the cross-section of the partition cavity 21 are different, and / or the shapes of each second foolproof part are different. By designing different positions and / or shapes for the second anti-mistake parts corresponding to each partition cavity 21, the accuracy of assembly of the bottle assembly 10 is improved so that each bottle 11 with an anti-mistake structure uniquely corresponds to one partition cavity 21 with an anti-mistake structure. The anti-mistake structure includes an anti-mistake protrusion 271 and an anti-mistake groove 116. For example, the first anti-mistake part includes an anti-mistake groove, and the second anti-mistake part includes an anti-mistake protrusion; or, the first anti-mistake part includes an anti-mistake protrusion, and the second anti-mistake part includes an anti-mistake groove. For example, as... Figure 8a and Figure 9 As shown, for bottles 11 of the same shape and volume, and for the corresponding partition cavities 21 of these bottles 11, the cavity wall of each partition cavity 21 is also provided with at least one anti-mistake protrusion 271 (e.g., Figure 9 As shown), a foolproof groove 116 is correspondingly provided on the bottom side wall of the material bottle 11 (as shown). Figure 8a As shown, the anti-mistake groove 116 cooperates with the anti-mistake protrusion 271 to achieve relative positioning between the bottle 11 and the partition cavity 21. Of course, it can also be reversed, for example, an anti-mistake groove is provided on the cavity wall of the partition cavity 21, and an anti-mistake protrusion is provided on the bottom side wall of the bottle 11.

[0082] The cavity wall of the partition cavity 21 includes a cavity sidewall and a cavity bottom wall. The cavity sidewall includes: two adjacent partitions 25 surrounding the partition cavity 21, and an inner cavity sidewall of the body 24 located between the two adjacent partitions 25. The cavity sidewall surrounds the cavity bottom wall to form the partition cavity 21. For example, as shown... Figure 9 As shown, the anti-mistake protrusion 271 can be provided on the side wall of the partition cavity 21. At least one anti-mistake protrusion 271 is provided on the partition 25, or at least one anti-mistake protrusion 271 is provided on the inner cavity side wall of the body 24 between two adjacent partitions 25, or at least one anti-mistake protrusion 271 is provided on each of the partition 25 and the inner cavity side wall of the body 24 between two adjacent partitions 25. In this embodiment, the provision and cooperation of the anti-mistake protrusion 271 and the anti-mistake groove 116 can, on the one hand, guide the insertion of the bottle 11 into the partition cavity 21, ensuring that the bottle 11 is placed in the correct position.

[0083] Furthermore, the position of each anti-mistake protrusion 271 on the sidewall of different partition cavities 21 can be different. Each bottle 11 has at least one anti-mistake groove 116 on its bottom sidewall, which corresponds to the anti-mistake protrusion 271. Thus, the positions of the anti-mistake protrusions 271 in each partition cavity 21 are different, and the positions of the anti-mistake grooves 116 on each bottle 11 are also different, thereby ensuring a one-to-one correspondence between multiple bottles 11 and multiple partition cavities 21, effectively preventing users from placing the bottles 11 in the wrong partition cavity 21. In a specific embodiment, in the region of the third partition cavity 21 corresponding to three small bottles 11, the anti-mistake protrusion 271 protrudes from different sidewalls of the partition cavity 21, to... Figure 9 As shown in the clockwise direction, for the first small partition cavity 21, a foolproof protrusion 271 is provided on its left partition 25; for the second small partition cavity 21, a foolproof protrusion 271 is provided on the inner wall of its body 24; and for the third small partition cavity 21, a foolproof protrusion 271 is provided on its right partition 25.

[0084] In some embodiments, at least one reinforcing rib 23 constitutes a foolproof protrusion 271, meaning the reinforcing rib 23 and the foolproof protrusion 271 can have the same structure. In other embodiments, the reinforcing rib 23 and the foolproof protrusion 271 described above have different structures, with at least one foolproof protrusion 271 located between two reinforcing ribs 23 in the cavity sidewall direction. Of course, the foolproof protrusion 271 is also a reinforcing rib, providing both foolproof protection and structural reinforcement to the turntable 20. In embodiments where the reinforcing rib 23 and the foolproof protrusion 271 have different structures, the protrusion height of the foolproof protrusion 271 on the cavity sidewall can also be greater than the protrusion height of the reinforcing rib 23 on the sidewall. Please refer to the references. Figure 3 Furthermore, as shown in Figure 12, the cooking device may also include a base 30, on which a discharge port 31 may be provided. A turntable 20 is rotatably connected to the base 30, allowing the turntable 20 to rotate relative to the base 30 until its feeding port 22 aligns with the discharge port 31 of the base 30. This allows the seasoning in the bottle 11 to be discharged into the cooking container through the discharge port 31. When the turntable 20 rotates, different feeding ports 22 can sequentially pass through the discharge port 31. During the addition of seasoning, the corresponding bottle 11 can be rotated to align with the discharge port 31, opening the one-way valve 112 and allowing the corresponding seasoning to be added. It is worth noting that, to ensure the discharge port 111 of the bottle 11 is closed in non-preset feeding states, in addition to closure via the one-way valve 112, other structures can be used for closure, such as the base 30 which rotates in conjunction with the turntable 20. Those skilled in the art can design such structures according to actual conditions; this application does not impose any particular limitations.

[0085] Please refer to the reference again. Figure 6To prevent seasoning from leaking out from the connection between the feeding port 22 and the dispensing port 111, thus causing the feeding device to become messy, in some embodiments, the cooking device may further include a sealing structure 71 for sealing the connection between the feeding port 22 and the dispensing port 111. In some embodiments, the sealing structure 71 includes, but is not limited to, a sealing ring, a sealing coating, a sealant, or an elastic soft rubber. Further, to prevent the sealing structure 71 from clogging the feeding port 22 and the dispensing port 111, the sealing structure 71 may be annular, with a diameter ranging from 5 mm to 50 mm, preferably 23 mm. In some embodiments, the sealing structure 71 is elastic, improving the sealing effect and reducing the pressure of the bottle 11 on the turntable. In some embodiments, within the turntable, at least a portion of the sealing structure 71 extends from the bottom wall of each partition cavity 21 into the cavity, with an extension height ranging from 4 mm to 20 mm, preferably 10 mm, and its extension height is less than the height of the side wall of the partition cavity 21. Specifically, the sealing structure 71 can be disposed on the turntable 20 and located at the feeding port 22. To prevent the sealing structure 71 from detaching from the turntable 20, in one embodiment, a sealing ring groove (not shown in the figure) is provided on the outer peripheral surface of the sealing structure 71, and a sealing ring rib 26 is provided on the hole wall of the feeding port 22 to seal and cooperate with the sealing ring groove. In this embodiment, after the sealing ring rib 26 and the sealing ring groove cooperate, the sealing structure 71 can be prevented from detaching from the vertical direction of the turntable 20. At the same time, it ensures that the sealing structure 71 is tightly fitted with the hole wall of the feeding port 22 on the turntable 20, and prevents the seasoning from seeping out from the connection between the sealing structure 71 and the turntable 20. In addition, the sealing ring groove refers to an annular groove, and the sealing ring rib 26 is a ring-shaped protrusion along the circumference of the feeding port 22. Of course, in some other embodiments, the sealing ring groove can also directly seal and cooperate with the entire hole wall of the feeding port 22 of the turntable 20, that is, the entire hole edge of the feeding port 22 is wrapped by the sealing ring groove.

[0086] like Figure 6 As shown, in one embodiment, a connecting ring rib 113 is provided on the bottom side of the material bottle 11 facing the turntable 20, and the connecting ring rib 113 surrounds the discharge port 111; when the material bottle 11 is installed on the turntable 20, the connecting ring rib 113 is inserted into the feeding port 22. The design of the connecting ring rib 113 at the bottom of the material bottle 11 to engage with the feeding port 22 can effectively improve the alignment accuracy between the discharge port 111 on the material bottle 11 and the feeding port 22 on the turntable 20. Specifically, the connecting ring rib 113 is inserted into the sealing structure 71, that is, the sealing structure 71 is sealed and fitted onto the outer circumferential surface of the connecting ring rib 113 to align the feeding port 22 with the discharge port 111, thereby preventing the material from leaking out from the connection between the connecting ring rib 113 and the sealing structure 71, and ensuring the sealed alignment between the discharge port 111 and the feeding port 22.

[0087] Furthermore, to improve the sealing effect between the sealing structure 71 and the connecting ring rib 113, in one embodiment, the inner circumferential surface of the sealing structure 71 is provided with at least one sealing lip 711, and the sealing structure 71 seals against the connecting ring rib 113 through the sealing lip 711. The sealing lip 711 protrudes from the inner circumferential surface of the sealing structure 71 and is inclined at a predetermined angle along the inner circumferential surface of the sealing structure 711. The angle between its inclination direction and the rotation axis is in the range of 60 degrees to 90 degrees, preferably 80 degrees; specifically, it extends towards the feeding port 22, which improves the sealing performance between the sealing structure 71 and the connecting ring rib 113 without affecting the smoothness of inserting the bottle 11 into the turntable 20; in a preferred embodiment, there are two sealing lips 711, and the two sealing lips 711 have the same inclination angle, preferably in the range of 30 degrees to 60 degrees with the rotation axis. By providing at least one sealing lip 711 on the inner circumferential surface of the sealing structure 71, the sealing lip 711, due to its more flexible deformation, can better adapt to the structure of the connecting ring rib 113 itself when in contact with it, making corresponding deformations and better fitting onto the connecting ring rib 113, thus achieving a better sealing effect. Optionally, the cross-section of the sealing lip 711 gradually decreases in its convex direction, equivalent to the end of the sealing lip 711 in contact with the connecting ring rib 113 being the small end, and the end of the sealing lip 711 connected to the inner circumferential surface of the sealing structure 71 being the large end. When compressed by the connecting ring rib 113, the small end of the sealing lip 711 can deform more flexibly to better adapt to this compression, thereby tightly fitting onto the connecting ring rib 113. Optionally, multiple sealing lips 711 are provided on the inner circumferential surface of the sealing structure 71, with each sealing lip 711 sealingly abutting against the connecting ring rib 113, achieving multiple seals.

[0088] Further details can be found in the appendix. Figure 4 and Figure 6 The end of the sealing structure 71 connected to the bottle 11 can be funnel-shaped. Along the direction of the base 30, the opening of the sealing structure 71 gradually becomes smaller to form a funnel shape, so that the end of the sealing structure 71 into which the bottle 11 is inserted forms a flared opening. When the connecting ring rib 113 of the bottle 11 is inserted into the sealing structure 71, the connecting ring rib 113 is inserted into the sealing structure 71 along the flared opening. The inclined inner wall of the flared opening guides and seals the connecting ring rib 113, making it convenient for the bottle 71 to be inserted and removed.

[0089] In this embodiment, the upper end of the sealing structure 71 is fitted onto the outlet 111 of the material bottle 11, and the lower end of the sealing structure 71 is fitted onto the wall of the feed port 22 of the turntable 20, thereby achieving a sealed connection between the outlet 111 and the feed port 22 and preventing the seasoning from leaking out from the connection between the outlet 111 and the feed port 22. Please refer to the reference. Figure 3 , Figure 4 , Figure 5 , Figure 9 and Figure 11 When the seasoning flows out from the feeding port 22 on the feeding unit 100 (in some embodiments, the feeding port 22 of the feeding unit 100 refers to the feeding port 22 of the turntable 20), it needs to be transported to the cooking container through the conveying pipe 81. During this process, to prevent the seasoning from accumulating below the feeding port 22 and adhering to the bottom surface of the turntable 20, thereby causing mixing and cross-contamination of flavors, in some embodiments, the cooking device may also include a buffer structure 60, which has a buffer cavity 63 with an opening, and the bottom wall of the buffer cavity 63 has a communication port 64 for adding seasonings into the cooking container. The feeding unit 100 includes a bottle assembly 10 and a turntable 20. The bottle assembly 10 is inserted into the turntable 20, and the bottle assembly 10 and the turntable 20 can move relative to the buffer structure 60 so that the feeding port 22 is aligned or misaligned with the opening of the buffer cavity 63. When aligned, the seasoning in the feeding unit 100 can flow through the feeding port 22 to the buffer chamber 63, and then through the buffer chamber 63 to the cooking container. When misaligned, the feeding port 22 is closed, and the seasoning cannot flow out.

[0090] In this embodiment, the seasoning flowing out of the bottle assembly 10 first flows into the buffer chamber 63 and then into the cooking container. The buffer chamber 63 provides a temporary storage place for the seasoning after it flows out of the bottle assembly 10, preventing the seasoning from filling the pipe and sticking to the bottom surface of the bottle assembly 10 or the turntable 20, thus causing mixing and affecting the taste of the food in the cooking container.

[0091] The bottle assembly 10 and the turntable 20 can move relative to the buffer structure 60. One possible implementation is that the bottle assembly 10 and the turntable 20 move while the buffer structure 60 remains stationary. Another possible implementation is that the bottle assembly 10 and the turntable 20 remain stationary while the buffer structure 60 moves. Yet another possible implementation is that the bottle assembly 10 and the turntable 20 move, and the buffer structure 60 moves, with the two moving relative to each other. Furthermore, the movement can include, but is not limited to, rotation about a rotation axis and linear motion. Since the turntable 20 has multiple feeding ports 22, which can be unevenly distributed along the circumference centered on the axis of rotation, and each feeding port 22 independently provides different seasonings, the turntable 20 can provide multiple seasonings. To further avoid mixing, such as preventing oil and water from mixing, in one embodiment, the buffer structure 60 includes two buffer cavities 63. Among the multiple feeding ports 22 of the turntable 20, there is a first feeding port 221 and a second feeding port 222. The turntable 20 can move relative to the buffer structure 60 to switch between multiple feeding positions, such as... Figure 15 As shown, at at least one of the feeding positions, the first feeding port 221 is aligned with the opening of one of the buffer chambers 63, as... Figure 17 As shown, at at least one other feeding position, the second feeding port 222 is aligned with the opening of another buffer chamber 63.

[0092] In practical applications, seasonings tend to adhere to the bottom wall of the buffer chamber 63. For example, liquid seasonings such as soy sauce and cooking oil will leave residues in the buffer chamber 63 to varying degrees. When another seasoning is added to the cooking container, this residue will mix with it. For some seasonings, mixing can be dangerous. For example, if oil and water in soy sauce are mixed, it can cause splattering or splattering when added to a heated cooking container. Therefore, in this embodiment, the two buffer chambers 63 are designed so that the first feeding port 221 and the second feeding port 222 output seasonings to the cooking container through different buffer chambers 63. In this way, the seasonings flowing out of the first feeding port 221 and the seasonings flowing out of the second feeding port 222 are completely independent, preventing them from mixing together. Taking seasonings, including oil, as an example, for edible oil, the second feeding port 222 can be used to discharge the oil, which is then fed into the cooking container through one of the buffer chambers 63; for other seasonings, including soy sauce, mixed seasonings, water, etc., the first feeding port 221 can be used to discharge the oil, which is then fed into the cooking container through another buffer chamber 63, thereby avoiding the mixing of oil and water.

[0093] To accommodate more seasonings, in one embodiment, the turntable 20 has multiple first feeding ports 221, such as... Figure 10b The feed ports 221b, 221c, 221d, and 221e are shown. Of course, the turntable 20 may also have multiple second feed ports 222. Figure 10b The diagram illustrates a turntable 20 with a second feeding port 222 (i.e., the feeding port 222 shown in the figure). It should be noted that each first feeding port 221 and each second feeding port 222 is connected to an independent buffer chamber 63. In one specific embodiment, the outlets of some bottles 11 are aligned with the first feeding port 221, and the outlets of some bottles 11 are aligned with the second feeding ports 222. When multiple first feeding ports 221 are provided, one of the multiple first feeding ports 221 is aligned with one buffer chamber 63. That is, each time seasoning needs to be added to the cooking container from the first feeding port 221, i.e., when the first feeding port 221 is in the feeding position, one and only one first feeding port 221 is aligned with one buffer chamber 63, rather than multiple first feeding ports 221 being aligned with the same buffer chamber 63. Similarly, when multiple second feeding ports 221 are provided, one of the multiple second feeding ports 222 is aligned with one buffer chamber 63. In some embodiments, the buffer chamber 63 includes a first buffer chamber 631 and a second buffer chamber 632. Four first feeding ports 221 add seasonings to the cooking container through the first buffer chamber 631, and second feeding ports 222 add seasonings to the cooking container through the second buffer chamber 632. The seasonings flowing through the first feeding ports 221 include liquid seasonings such as water, mixed seasonings, and soy sauce, and the seasonings flowing through the second feeding ports 222 include edible oil.

[0094] like Figure 5 and Figure 11 As shown, to facilitate better flow of seasonings into the buffer cavity 63 and concentrate their flow out of the buffer cavity 63, in one embodiment, the connecting opening 64 of the buffer cavity 63 can be opened directly opposite the open end of the buffer cavity 63, and the buffer cavity 63 gradually expands in the direction from the connecting opening 64 to the open end. Taking the up-down direction as an example, the open end of the buffer cavity 63 faces upward, and the connecting opening 64 is located at the bottom of the buffer cavity 63. The buffer cavity 63 is set in the shape of a cone, with the inner diameter gradually decreasing from the direction of seasoning flow, so that the upper end can easily receive the seasonings flowing out from the first feeding port 221 or the second feeding port 222, while the lower end facilitates the concentrated flow of seasonings from the connecting opening 64 into the cooking container.

[0095] To facilitate the overall installation of the buffer structure 60, in some embodiments, the buffer structure 60 may have a connecting plate 61 and two buffer parts 62 connected thereto. Each buffer part 62 has a buffer cavity 63 and a connecting port 64. The two buffer cavities 63 are distributed in a circumferential direction with the rotation axis as the center, and the two buffer cavities 63 are spaced apart by a predetermined circumferential angle, which ranges from 30 degrees to 60 degrees, preferably 45 degrees. By connecting the two buffer parts 62 together on a connecting plate 61, it is not necessary to position and install each buffer part 62 individually during installation. It is only necessary to accurately align one buffer part 62 or the connecting plate 61 to achieve the alignment of the other buffer part 62. At the same time, during transportation, the two buffer parts 62 form a whole, which also reduces the risk of scattering due to the small size of the parts.

[0096] In some embodiments, the buffer structure 60 can be made of plastic, including but not limited to polyethylene, polypropylene, and polyvinyl chloride. The connecting plate 61 and the two buffer portions 62 can be integrally injection molded. Integral injection molding eliminates the need for assembly steps between the three components, preventing gaps between the buffer portions 62 and the connecting plate 61 that could lead to material spillage; it also enables mass production of the parts. Please refer to the reference again. Figure 5 and Figure 11 To prevent the seasoning from leaking out between the buffer structure 60 and the turntable 20, in one embodiment, the buffer structure 60 also has a sealing element 65. The sealing element 65 can surround the edge of the opening. When the turntable 20 rotates to the feeding position, the sealing element 65 seals against the edge of the first feeding port 221 or the second feeding port 222, thereby achieving the sealing alignment of the first feeding port 221 and the buffer cavity 63 during feeding, or achieving the sealing alignment of the second feeding port 222 and the buffer cavity 63, thus preventing the seasoning from leaking out during the feeding process.

[0097] It should be noted that when the turntable 20 is in the feeding position, the sealing member 65 sealingly abutting against the edge of the first feeding port 221 or the second feeding port 222 means that when the first feeding port 221 is aligned with the buffer cavity 63, the sealing member 65 on the buffer cavity 63 sealingly abuts against the edge of the first feeding port 221; and when the second feeding port 222 is aligned with the buffer cavity 63, the sealing member 65 on the buffer cavity 63 sealingly abuts against the edge of the second feeding port 222. The sealing member 65 can generally be annular, and its diameter is greater than or equal to the opening diameter of the buffer cavity 63. In some embodiments, the opening diameter of the buffer cavity ranges from 10 mm to 40 mm, preferably 21 mm. When at least two buffer cavities 63 are provided, a sealing member 65 can be provided around the opening of each buffer cavity 63, and the sealing member 65 surrounds the buffer cavity 63. Alternatively, at least two buffer cavities 63 can share a single sealing member 65, that is, the sealing member 65 surrounds both buffer cavities 63. The sealing element 65 can be made of rubber, silicone, or other materials to provide elasticity and achieve elastic contact sealing. To improve the contact effect between the sealing element 65 and the bottom surface of the turntable 20, in some embodiments, the sealing element 65 can be pleated, extending from the opening of the buffer cavity 63 towards the feeding unit 100 (i.e., towards the turntable 20), with multiple recesses and protrusions alternately distributed in its axial extension direction. The recesses and protrusions are all annular, thereby increasing the deformation space of the sealing element 65 and enabling better sealing contact with the bottom surface of the turntable 20.

[0098] To achieve the installation of the seal 65 and the buffer structure 60, one possible approach is to provide a mounting annular groove (not shown) on the buffer structure 60, with the seal 65 partially embedded within the mounting annular groove. Another possible approach is to provide a raised rib on the buffer structure 60 at the opening, with the rib surrounding the opening, and a groove on the seal 65 matching the raised rib, so that the seal 65 is fixed to the raised rib. In some embodiments, the seal 65 and the buffer cavity 63 are integrally formed.

[0099] Please refer to the reference. Figures 11 to 13 In some embodiments, the buffer structure 60 is mounted on the base 30. One possible installation method is that the upper surface of the base 30 has a mounting cavity 32, and the buffer structure 60 can fit into the mounting cavity 32. Specifically, the mounting cavity 32 includes a recess 321 and a clearance opening 322 opened at the bottom of the recess 321. The connecting plate 61 of the buffer structure 60 can fit into the recess 321, and the buffer portion 62 of the buffer structure 60 can extend into the clearance opening 322. When two buffer portions 62 are provided, two clearance openings 322 are correspondingly provided on the base 30. In this embodiment, the buffer structure 60 and the mounting cavity 32 are fitted together, which facilitates the positioning and installation of the buffer structure 60, and also avoids the buffer structure 60 protruding outside the base 30 and colliding with and being damaged by other components.

[0100] It should be noted that when the buffer structure 60 is provided, the buffer cavity 63 constitutes the material discharge port 31 of the base 30. When the buffer structure 60 is not provided, the material discharge port 31 can be directly formed by opening a hole in the base 30. Figure 12b for Figure 12a The corresponding simplified top view shows a case where the base 30 has two discharge ports 31 (i.e., discharge port 311 and discharge port 312); in a specific example, see [reference needed]. Figure 11 As shown, the discharge port 311 can be composed of a buffer cavity 632, and the discharge port 312 can be composed of a buffer cavity 631.

[0101] Please refer to the reference. Figure 3 and Figure 5 In the above description, the bottle assembly 10 and the turntable 20 are movable relative to the buffer structure 60, including the bottle assembly 10 and the turntable 20 themselves moving while the buffer structure 60 is fixed in position, or the bottle assembly 10 and the turntable 20 being fixed while the buffer structure 60 is movable. The movement includes, but is not limited to, rotation and linear movement. Specifically, in one embodiment, the bottle assembly 10 and the turntable 20 are rotatably connected to the base 30 so as to move at multiple feeding positions through circumferential rotation. Figure 15 and Figure 17 The rotary table 20 of the feeding unit 100 is switched between the feeding position and the feeding position.

[0102] Furthermore, the cooking equipment also includes a conveying pipe 81. The discharge port 31 of the base 30 is used to communicate with the cooking container through the conveying pipe 81, which is used to transport the seasonings flowing out of the discharge port 31 to the cooking container. Since the conveying pipe 81 can be used to transport at least two different seasonings, in order to further improve the mixing phenomenon that occurs during the two conveying processes, some embodiments of this application also include an emptying position 122 (e.g., ...). Figure 10b As shown, the bottle assembly 10 and the turntable 20 can switch between a feeding position and an emptying position relative to the base 30. To enable this switching, in some possible embodiments, the turntable 20 is rotatably mounted on the base 30. During rotation of the turntable 20 relative to the base 30, the feeding port 22 and the discharge port 31 can switch between aligned and misaligned states. Specifically, when the turntable 20 is in the feeding position, the feeding port 22 and the discharge port 31 are aligned. When the turntable 20 is in the emptying position, the feeding port 22 and the discharge port 31 are misaligned. In some embodiments, the diameter of the conveying pipe 81 ranges from 2 mm to 10 mm, preferably 7.5 mm, to ensure smooth flow of various liquid mixtures to the cooking container.

[0103] When the feeding unit 100 is in the assembled state, the bottle 11 is inserted into the turntable 20. The turntable 20, which holds the bottle 11, is rotatably connected to the base 30. There is a preset gap between the base 30 and the turntable 20 (or the feeding unit 100). When the feeding port 22 and the discharge port 31 are misaligned, the discharge port 31 can communicate with the preset gap to form a cleaning channel. The so-called communication between the discharge port 31 and the preset gap means that the auxiliary cleaning medium in the preset gap can be transported to the discharge port 31. Under the action of the cleaning medium, the residual seasoning in the discharge port 31 and the conveying pipe 81 connected to the discharge port 31 is guided into the cooking container, avoiding the seasoning residue from the previous feeding remaining in the conveying pipe 81 and mixing with the seasoning of the next feeding, thus preventing mixing. Furthermore, purging the discharge port 31 and conveying pipe 81 after adding ingredients reduces the probability of bacteria growth or even mold due to prolonged retention of seasonings in the discharge port 31 and / or conveying pipe 81. Moreover, purging after each addition allows for secondary seasoning discharge, ensuring the predetermined amount of seasoning is accurately dispensed into the cooking container. Taking air as the cleaning medium as an example, one method for removing residual seasoning is as follows: when the turntable 20 is in the purging position, the cleaning channel is connected to both external air and the discharge port 31. External air enters the discharge port 31 through the cleaning channel, and under the influence of the airflow, residual seasonings in the discharge port 31 and conveying pipe 81 can flow into the cooking container.

[0104] It should be noted that in some other embodiments, the cleaning medium may also be water or a mixture of water and detergent. For information on how to use water or a mixture of water and a washing machine to empty residual seasoning from the discharge port 31 and the conveying pipe, please refer to the above or the following related content.

[0105] Compared to using through holes in the turntable 20 as a cleaning channel, which compromises the integrity of the turntable 20 and makes cleaning difficult, a pre-set gap between the base 30 and the turntable 20 creates a cleaning channel. This eliminates the need for holes in the turntable 20, simplifying the process and reducing the difficulty of use and maintenance. A conveying pipe 80 connects the main body 2000 and the feeding device 1000, allowing seasonings to be transported to the cooking container. The cleaning channel is connected to the conveying pipe 80. Therefore, during evacuation, residual seasonings in the conveying pipe 80 can be completely drained, ensuring reliable feeding each time and preventing residual seasonings from causing inaccurate feeding. To achieve the pre-set gap between the turntable 20 and the base 30, see [details omitted]. Figure 10aAs shown, a protrusion 22a may be provided on the side of the turntable 20 facing the base 30 and surrounding the feeding port 22. The protrusion 22a surrounds the feeding port 22. Since the protrusion height of the protrusion 22a relative to the turntable 20 is h, a preset gap exists between the base 30 and the turntable 20. In some embodiments, the height h ranges from 0.5 mm to 10 mm, preferably 3 mm. A sealing member 65 is provided on the side of the discharge port 31 facing the feeding unit 100. The sealing member 65 surrounds the discharge port 31 and is used to press against the protrusion 22a to ensure a sealed connection between the feeding port 22 and the discharge port 31. When the feeding port 22 and the discharge port 31 are aligned, the protrusion 22a and the sealing element 65 can form a seal, and the two can be tightly squeezed together, preventing external air and other media from entering the feeding port 22 and the discharge port 31. In this state, the discharge port 111 can be opened, and the feeding port 22 and the discharge port 31 are connected to form a channel for conveying seasoning. When the feeding is completed, the control system can control the turntable 20 to rotate relative to the base 30 to a preset angle. After rotating to the preset angle, the feeding port 22 and the discharge port 31 are misaligned, and the discharge port 31 is opposite to the surface of the turntable 20 facing the base 30. There is a preset gap between the discharge port 31 and the surface of the turntable 20 facing the base 30, so that the cleaning medium in the preset gap can enter the discharge port 31. It should be noted that the protrusion 22a mentioned above may include a hard protrusion or an elastic protrusion. This application embodiment does not make any special limitation. When the protrusion 22a includes an elastic protrusion, the protrusion 22a can be elastically aligned with the discharge port 31 to improve the sealing performance when the feeding port 22 and the discharge port 31 are aligned, and prevent the material from leaking out from the alignment surface of the feeding port 22 and the discharge port 31 during the feeding process.

[0106] like Figure 10aAs shown, exemplarily, the feeding port 22 may include multiple feeding ports, each feeding port 22 corresponding to a protrusion 22a. These protrusions 22a are unevenly distributed in a circumferential direction centered on the rotation axis of the turntable 20. Exemplarily, the protrusions 22a corresponding to each feeding port 22 may have the same shape, or some of the protrusions 22a may have the same shape while others have different shapes. Protrusions 22a of the same shape are used to align with one discharge port 31, while protrusions 22a of different shapes are used to align with another discharge port 31. Specifically, the shape of the protrusion 22a corresponding to the feeding port 22 for edible oil output may differ from the shapes of the protrusions 22a corresponding to other feeding ports 22. For example, the diameter of the protrusion 22a corresponding to the feeding port 22 for edible oil output may be larger than the diameter of the protrusions 22a corresponding to other feeding ports 22. Multiple protrusions 22a are distributed in a circumferential direction centered on the rotation axis of the turntable 20, so that during the rotation of the turntable 20 relative to the base 30, the material discharge port 31 can sequentially engage and align with the protrusions 22a.

[0107] A protrusion 22a is provided on the bottom surface of the turntable 20 facing the base 30. The protrusion 22a extends from the outer surface of the bottom of the turntable 20 toward the base 30 to a predetermined height, ranging from 0.5 mm to 10 mm, preferably 3 mm. Therefore, a predetermined gap is formed between any two protrusions 22a between the turntable 20 and the base 30. A preset gap is formed between the area between two adjacent protrusions 22a and the base 30. Figure 10aAs shown, taking five feeding ports 22 corresponding to five protrusions 22a as an example, three of the feeding ports 22 are close together, while the other two are far apart. The gaps between the protrusions 22a corresponding to the three closer feeding ports 22 are slightly smaller. Therefore, when controlling the feeding device to perform the emptying operation, the system can accurately sense the angle rotated by the turntable 20. When the turntable 20 rotates to the point where one of the discharge ports 31 is directly opposite the gap between the two closer protrusions 22a, the feeding device is controlled to perform the emptying operation. The area between the protrusions 22a corresponding to the two farther feeding ports 22 is larger. When the area between the two farther protrusions 22a is opposite to a discharge port 31, the system can control the feeding device to perform the emptying operation. Alternatively, the system can control the feeding device to perform the emptying operation only when the discharge port 31 is located at a preset position in the area between the two farther protrusions 22a, thus making the control more precise. More specifically, the protrusion height of each protrusion 22a is equal. The protrusion height of a protrusion 22a refers to the height of the protrusion 22a protruding from the surface of the turntable 20 facing the base 30. Because the protrusion height of each protrusion 22a is equal, the fit between each protrusion 22a and the material outlet 31 is essentially the same during the rotation of the turntable 20 relative to the base 30. This prevents large variations in resistance experienced by the turntable 20 during rotation due to differences in the protrusion height of individual protrusions, thus avoiding any situation where the rotation of the turntable 20 relative to the base 30 is not smooth.

[0108] In some specific embodiments, the protrusion 22a may include an elastic sealing ring, which may be annular and embedded in the inner wall of the feeding port 22 for elastic compression contact with the discharge port 31, so that the feeding port 22 and the discharge port 31 can be sealed and aligned. The protrusion 22a may be formed solely by the elastic sealing ring, or the protrusion 22a may include a rigid protrusion and an elastic sealing ring embedded in the rigid protrusion. By providing the elastic sealing ring, the feeding port 22 and the discharge port 31 can be elastically and sealingly contacted, thereby further reducing the risk of external media entering the conveying channel through the gap between the feeding port 22 and the discharge port 31, and also reducing the risk of the seasoning leaking out from the gap between the feeding port 22 and the discharge port 31.

[0109] For details, please see Figure 11A sealing element 65 is provided on the side of the discharge port 31 facing the turntable 20. The sealing element 65 surrounds the discharge port 31 and is used to press against the elastic sealing ring of the protrusion 22a to ensure that the feeding port 22 and the discharge port 31 are sealed and aligned. In the installed state, the sealing element 65 can protrude from the surface of the base 30 facing the turntable 20. In some embodiments, the sealing element 65 can be the sealing element 65 described in the above embodiments, that is, a buffer structure 60 is provided at the discharge port 31, and the sealing element 65 is fixed to the buffer structure 60. For specific implementation, please refer to the description of the buffer structure 60 and the sealing element 65 in the above embodiments. In other embodiments, the sealing element 65 can be directly fixed to the surface of the base 30 facing the turntable 20. For example, an annular groove is provided at the edge of the discharge port 31 of the base 30, and the sealing element 65 is inserted into the annular groove, or the sealing element 65 is directly bonded to the periphery of the discharge port 31. The elastic sealing ring at the protrusion 22a and the sealing element 65 at the discharge port 31 are aligned to make the seal between the feeding port 22 and the discharge port 31 more reliable.

[0110] The technical solution provided in the above embodiments, due to the existence of a preset gap, ensures that the feeding port 22 and the discharge port 31 only make tight contact when aligned. In the misaligned state, the turntable 20 and the base 30 are in a clearance fit. This prevents the elastic sealing ring of the feeding port 22 and the sealing element 65 of the discharge port 31 from being under prolonged compression and deformation, thus significantly shortening their service life. Furthermore, the gap creates a cleaning channel, avoiding the need for additional openings on the turntable 20, simplifying manufacturing and making the structural design more rational. The protrusion 22a includes a top surface 22a1 that contacts the sealing element 65. When the feeding port 22 and the discharge port 31 are aligned, the sealing element 65 is in compression contact with the top surface 22a1. This top surface 22a1 can be parallel to the surface of the turntable 20 facing the base 30. By designing a top surface 22a1 and a sealing element 65, the sealing element 65 can be accurately and reliably aligned with the protrusion 22a. Furthermore, as the turntable 20 rotates relative to the base 30, the seal 65 slides laterally across the top plane 22a1, resulting in low frictional resistance between the top plane 22a1 and the seal 65. This ensures that the seal 65 and the protrusion 22a are properly aligned and sealed, without affecting the relative rotation between the turntable 20 and the base 30.

[0111] For more details, please refer to the appendix. Figure 10aThe protrusion 22a may be trumpet-shaped, and the trumpet-shaped protrusion 22a may include an annular inner hole S1 and an annular outward expansion S2 surrounding the inner hole S1. The inner hole S1 is located inside the top plane 22a1, and the outward expansion S2 is located outside the top plane 22a1. The inner hole S1 extends into the inside of the feeding port 22 and connects with the inner wall of the feeding port 22. The outward expansion S2 extends from the top plane 22a1 to fit against the surface of the turntable 20 facing the base 30, and the protrusion height of the outward expansion S2 gradually decreases along the radial outward direction of the feeding port 22. In some embodiments, the inner hole S1 is configured as an elastic sealing ring for the protrusion 22a, which can be adhered to the inner wall of the feeding port 22 or inserted into the feeding port 22. The protrusion height of the outwardly expanding portion S2 gradually decreases, meaning that the highest protrusion is at the end of the outwardly expanding portion S2 closest to the top plane 22a1, forming the highest protrusion point. The end of the outwardly expanding portion S2 away from the inner hole portion S2 is in contact with the surface of the turntable 20 facing the base 30, and the protrusion height at the contact point is zero. The protrusion 22a is funnel-shaped, meaning that the outwardly expanding portion S2 extends from the top plane 22a1 towards the bottom outer surface of the turntable 20, and the radius of its annular cross-section gradually increases. The entire protrusion 22a can be a smooth funnel shape, thus, during the relative rotation of the turntable 20 and the base 30, the protrusion 22a smoothly transitions with the seal 65 on the base 30, and the rotational resistance of the protrusion 22a to the base 30 is small.

[0112] In some embodiments, such as Figure 10a As shown, the outward expansion portion S2 may include multiple coaxially arranged annular connecting portions S21. The multiple annular connecting portions S21 are connected and arranged in a stepped manner radially outward along the feed port 22. The multiple annular connecting portions S21 are connected in a pleated manner. When the protrusion 22a is aligned with the seal 65, because the outward expansion portion S2 is pleated, the outward expansion portion S2 can compress the seal 65 axially according to the deformation direction defined by the pleats, and it is not easy for the seal 65 to tilt or deflect in the radial direction, thereby ensuring reliable alignment of the protrusion 22a and the seal 65 at the predetermined position.

[0113] This application embodiment also provides a feeding device, including: a base 30, a seasoning bottle assembly 10, and a turntable 20. The base 30 has a discharge port 31, which is connected to a cooking container through a conveying pipe 81. The seasoning bottle assembly 10 is used to hold seasonings. The turntable 20 is used to support the seasoning bottle assembly 10 and is rotatably mounted on the base 30. The turntable 20 includes a feeding port 22 for seasoning output. During the rotation of the turntable 20 relative to the base 30, the feeding port 22 and the discharge port 31 can switch between an aligned state and a misaligned state. There is a preset gap between the base 30 and the turntable 20, which ranges from 1 mm to 10 mm, preferably 4.5 mm. When the feeding port 22 and the discharge port 31 are in the aligned state, their positions are aligned. When the feeding port 22 and the discharge port 31 are in the misaligned state, the discharge port 31 can communicate with the preset gap to form a cleaning channel.

[0114] To visually demonstrate the switching process of the feeding port 22 between aligned and misaligned states as the turntable 20 rotates relative to the base 30, please refer to [link to documentation]. Figures 19a to 19e As shown, in Figure 10b Based on the top view of the bottom surface of the turntable 20, the multiple material discharge ports 31 provided on the base 30 are also schematically shown. Specifically, any one of the multiple first curves "---" drawn in the figure to visually represent the positional relationship of the multiple feeding ports 22 (or the positional relationship of the emptying positions 122) on the turntable 20, and any one of the multiple second curves drawn to represent the positional relationship of the multiple material discharge ports 31, are considered as different from the first curves. When any of the second curves in the graph coincides, it indicates that the feed port 22 (or discharge position 122) indicated by the first curve in the graph is aligned with the discharge port 31 indicated by the second curve, that is, the feed port 22 and the discharge port 31 are in a aligned (or misaligned) state. For example, see Figure 19b As shown in the figure, the overlap of the first curve l1 and the second curve l2 indicates that the feeding port 222 on the turntable and the discharging port 312 on the base are aligned; wherein, Figure 19b The first curve l1 and the second curve l2 are shown slightly offset to facilitate their identification. For more information on the venting position, please refer to the following related content.

[0115] exist Figures 19a to 19e middle, Figure 19b and Figure 19d The diagram shows a turntable with multiple insertable bottles 11 in the feeding position, wherein... Figure 19b This shows that the feeding port 222 and the discharge port 312 are aligned, that is, the feeding port 222 and the discharge port 312 are in a state of alignment. Figure 19dThis shows the alignment of the feed port 221c with the discharge port 311. Figure 19c and Figure 19e This shows the turntable with multiple insertable bottles 11 in the empty position, specifically, that is... Figure 19c This illustrates a situation where the feed port 222 and the discharge port 312 are misaligned. Figure 19e This shows a situation where the feed port 221c and the discharge port 311 are misaligned.

[0116] for Figure 19a This illustrates the state where the turntable 20 is positioned at a reference position. In this embodiment, the turntable 20 is positioned at a reference position to facilitate subsequent control of its rotation relative to the base 30, enabling switching between aligned and misaligned states between the feeding port 22 and the discharge port 31, thereby achieving automatic feeding. In specific implementation, the reference position may refer to the origin position of the turntable 20 and the base 30. Figure 12b The positional relationship of the multiple material discharge ports 31 shown, and Figure 10b The positions of the multiple feeding ports 22 on the turntable shown are all based on the origin position. Each time the feeding device 10 is activated to achieve automatic feeding for a dish to be cooked, the turntable 20 is first positioned to the reference position. After the turntable 20 is positioned to the reference position, the turntable 20 is controlled to rotate in the supported rotation direction, rotating at least one feeding port connected to the material bottle 11 to the corresponding dispensing port 31 position in sequence to achieve the automatic feeding function.

[0117] Here, considering that the turntable 20 is often randomly installed at different angles when the user assembles the feeding device, there may be situations where the turntable is in a position other than the set reference position. This would prevent the implementation of the automatic feeding function; or, if a program error occurs during the execution of the automatic feeding task, it may need to be reset to the reference position, etc. All of these require the feeding device to have the function of automatically positioning the turntable to the reference position. Based on this, in order to achieve the function of positioning the turntable 20 to the reference position, in some embodiments, see... Figure 10b and Figure 12bAs shown, a trigger element 123 may also be provided on the turntable 20, and correspondingly, a sensor element 39 may also be provided on the base 30. The trigger element 123 and the sensor element 39 are components capable of triggering each other or cooperating to generate a sensing signal, and the sensing signal varies depending on the relative position between the trigger element 123 and the sensor element 39. The trigger element 123 is disposed on the turntable 20, which rotates relative to the base 30. Therefore, the change in the relative position between the trigger element 123 and the sensor element 39 is mainly caused by the rotation of the trigger element 123 with the turntable 20. Of course, in some other embodiments, when the base 30 can rotate relative to the turntable 20, the change in the relative position between the trigger element 123 and the sensor element 39 may also be caused by the rotation of the sensor element with the base, etc., which is not limited here.

[0118] In specific settings, the positions of the sensor 39 on the base 30 and the trigger 123 on the turntable 20 are both related to a reference position. For example, the sensor 39 can be positioned at the reference position or at a certain angle from the reference position; this positional relationship is predefined. Similarly, the trigger 123 can also be positioned at the reference position or at a certain angle or distance from the reference position; this positional relationship is also predefined. Thus, based on the predefined positional relationship between the sensor and the trigger relative to the reference position, the turntable can be positioned at the reference position using the sensing signal between the sensor 39 and the trigger 123. For example, suppose... Figure 10b and Figure 12b The sensor 39 and trigger 123 shown are positioned at reference positions. During the process of controlling the turntable 20 to rotate relative to the base 30 to position the turntable 20 at the reference position, the turntable 20 can be stopped rotating when the sensing signal between the sensor 39 and the trigger 123 reaches its strongest value, thereby positioning the turntable 20 at the reference position. Specifically, the sensing signal between the trigger 123 and the sensor 112 reaches its strongest value when the trigger 123 is rotated to align with the position of the sensor 112, that is, when the trigger 123 is rotated to align with the position of the first discharge port 311. Figure 19a This diagram illustrates the turntable 20 when it is positioned at a reference position. For details on the specific implementation process of positioning the turntable at the reference position, please refer to the relevant content in the embodiments below.

[0119] It should be noted that, in addition to the methods described above, in other embodiments, the sensor and trigger can also be mounted on the turntable 20 and the trigger on the base 30, as long as there is a change in position signal between them. This embodiment does not limit the specific location and form of the sensor and trigger. Specifically, the sensor and trigger can be implemented as follows: For example, the sensor can be a microswitch and the trigger can be a protrusion. The microswitch is connected to the controller. When the turntable 20 rotates relative to the base 30, the protrusion also rotates with the turntable 20. When the protrusion rotates to the position corresponding to the microswitch, it can trigger the microswitch. At this time, the microswitch sends a sensing signal, such as a current signal, to the controller. The controller positions the turntable to a reference position based on the detected sensing signal. Another example is that the sensor can be a Hall element and the trigger can be a magnetic sensor. When the turntable 20 rotates relative to the base 30, the sensing signal between the magnetic sensor and the Hall element changes continuously. At this time, the Hall element sends a sensing signal, such as a current signal, to the controller. The controller positions the turntable to a reference position based on the detected sensing signal. In addition to the forms shown above, the sensing element and triggering element may also include different specific embodiments such as photoelectric switches and reflectors, infrared sensors and protrusions, which will not be described in detail here. Those skilled in the art can choose flexibly, as long as the triggering element and sensing element can generate a sensing signal when the turntable 20 rotates. In this embodiment, a Hall element is preferably selected as the sensing element and a magnetic induction element as the triggering element.

[0120] Furthermore, after positioning the turntable 20 at the reference position, before using the feeding device to achieve the automatic feeding function, it is generally necessary to obtain the seasoning information stored in each bottle connected to the multiple feeding ports on the turntable 20, in order to provide data support for the subsequent automatic feeding function. In specific implementation, this can be achieved by setting different partitioned chambers on the turntable 20, with each partitioned chamber fitting into a fixed bottle, thus enabling the acquisition of the seasoning information stored in each of the multiple bottles. For example, see... Figure 9 , Figure 10b and Figures 19a to 19e As shown, the turntable 20 has five different partitioned chambers 21. Using partition chamber 21a as a base point, the seasonings stored in the bottles fixedly inserted into each of the five different partitioned chambers 21 in a clockwise direction can be cooking oil, salt, light soy sauce, dark soy sauce, and water. Similarly, using the feeding port 222 as a base point, the seasonings stored in the bottles fixedly inserted into each of the five different feeding ports 121 in a clockwise direction are cooking oil, salt, light soy sauce, dark soy sauce, and water. This fixed insertion relationship between the feeding ports and the seasoning bottles, along with the seasoning information stored in the corresponding bottles, is pre-stored in a memory for retrieval when needed, thus enabling the retrieval of the seasoning information stored in the multiple bottles 11 on the turntable 20.

[0121] Alternatively, a data reader / writer can be installed on the base 30, and a corresponding electronic tag can be set on each bottle 11. The data reader / writer reads the electronic tags on the bottles 11 to obtain the seasoning information stored in multiple bottles. In specific implementation, the data reader / writer can be, but is not limited to, a barcode reader (such as an NFC reader), an RFID reader / writer, etc. The data reader / writer can be set at a reference position, such as the inner wall of the dispensing port 222, or at other positions, which are not limited here. Correspondingly, the electronic tag can be an NFC tag, and the electronic tag can be set on, but is not limited to, the inner wall of the dispensing port of the bottle. This embodiment does not specifically limit the specific setting position of the data reader / writer and the electronic tag, as long as it can ensure that the data reader / writer can read the corresponding electronic tag. The specific setting position of the data reader / writer and the electronic tag is not shown in the attached drawings.

[0122] like Figure 19a As shown, after the turntable 20 is positioned at the reference position, based on the pre-stored positional relationship of the feeding ports of each compartment on the turntable 20 and the relative positional relationship of the deployed data readers relative to the reference setting, the turntable can be controlled to rotate in a certain direction (such as counterclockwise or clockwise) to sequentially rotate multiple bottles inserted on the turntable to the position of the data readers. The data readers then sequentially read the electronic tags of each bottle, thereby obtaining the seasoning information stored in each of the multiple bottles. For example, see... Figure 19a As shown, assuming the data reader is set at the dispensing port 312, rotating the turntable 20 counterclockwise by 95° (56.25° + 56.25° + 32.5° - 50°) aligns the feeding port 222 with the dispensing port 312. The data reader reads the electronic tag on the bottle connected to the feeding port 222. Upon completion of the reading, the reader associates the read data with the feeding port 222 and stores it in the corresponding memory, while simultaneously sending a feedback notification to the controller indicating completion. Based on the received feedback notification, the controller can again rotate the turntable 20 counterclockwise by 62.5° (31.25° + 31.25°) to align the feeding port 121b with the dispensing port 312, thereby reading the electronic tag on the bottle 11 connected to the feeding port 121b. This process is repeated until all the seasoning information stored in the bottles connected to the feeding ports on the turntable is read.

[0123] This embodiment also does not specifically limit the method of obtaining the seasoning information stored in multiple bottles. In this preferred embodiment, the first method mentioned above is preferred, that is, the method of each partition cavity being adapted and inserted into a fixed bottle to obtain the seasoning information stored in each of the multiple bottles.

[0124] As can be seen from the above, when using a feeding device to achieve automatic feeding, it is generally necessary to first position the turntable at a reference position and obtain the seasoning information stored in the bottles connected to each feeding port on the turntable, so as to provide data support for the subsequent automatic feeding function. It should be noted that, to facilitate the addition of seasonings to the cooking container using the feeding device, the seasonings in each of the multiple bottles 11 mentioned above are all in liquid form. For non-liquid seasonings, they can be diluted with water to form a liquid and then placed in the corresponding bottle. For example, edible salt can be diluted with water to form brine and then placed in the corresponding bottle; solid seasonings such as ginger, garlic, and chili can be ground into powder, diluted with water to form a mixed seasoning, and then placed in the corresponding bottle, etc.

[0125] In addition to the components described above, the feeding device may also include other basic components, such as a controller for controlling the rotation of the turntable and the dispensing of materials from the bottles. Detailed information about the controller can be found in the relevant sections below. Another example is a memory, used to store one or more computer instructions for the controller to access, and also to store data such as the positional relationships between the multiple feeding ports 22 and multiple evacuation positions 122 on the turntable 20, the positional relationships between the multiple discharge ports 31 on the base 30, the seasoning information stored in the bottles connected to each feeding port 22, and the correspondence between the discharge ports 31 and the seasoning types. The data stored in the memory can provide data support for the controller to implement the control methods, feeding methods, and other logical functions provided in the various embodiments of this application.

[0126] It should be noted that the positional relationship between the multiple venting positions 122 does not necessarily need to be stored in the memory. When a venting position 122 is needed, the corresponding venting position 122 can be determined directly based on the positional relationship between the multiple feeding ports 22. For example, see... Figure 19c As shown, a corresponding venting position is set at the midpoint between every two adjacent feeding ports. Therefore, after a target seasoning is fed through the corresponding target feeding port, the corresponding venting position can be directly determined based on the positional relationship between the target seasoning bottle and its adjacent bottles, and the venting position can be rotated to align with the target feeding port. Specifically, for example, as... Figure 19b As shown, after the seasoning in the bottle connected to the feeding port 222 is fed through the discharge port 312, the position of the emptying position between the two can be determined directly based on the positional relationship between the feeding port 222 and the adjacent feeding port 221b. The emptying position between the two can then be rotated to align with the position of the discharge port 312, so that the feeding port 222 and the discharge port 311 are misaligned to achieve the emptying operation. For the specific implementation process, please refer to the relevant content in the embodiments below.

[0127] It should also be noted that the feeding device provided in this embodiment has the same structure and function as the feeding device in the cooking equipment of the above embodiments. For details, please refer to the description of the above embodiments, which will not be repeated here.

[0128] One embodiment of this application also provides another cooking device, including: a main body and a feeding device; wherein, the main body has a cooking container; the feeding device includes: a base 30 and a feeding unit 100. The base 30 has a discharge port 31; the feeding unit 100 is movably disposed on the base 30 and can move relative to the base 30, the feeding unit 100 includes a feeding port 22; during the movement of the feeding unit 100 relative to the base 30, the feeding port 22 and the discharge port 31 can switch between an aligned state and a misaligned state; there is a preset gap between the base 30 and the feeding unit 100, and when the feeding port 22 and the discharge port 31 are in a misaligned state, the discharge port 31 can communicate with the preset gap to form a cleaning channel. The feeding unit 100 is used to provide the seasonings required for cooking, and the seasonings can be conveyed to the base 30 through the feeding port 22. In some embodiments, the feeding unit 100 may include a bottle assembly 10 for containing seasonings and a turntable 20 for receiving the bottle assembly 10. The bottle assembly 10 and the turntable 20 may be detachably connected or fixedly connected. The feeding unit 100 is movably disposed on the base 30 and may be movably disposed on the base 30 by means of rotation, sliding, or other movements. Therefore, the relative movement between the feeding port 22 and the discharging port 31 includes, but is not limited to, relative rotation and relative movement, as long as the feeding port 22 and the discharging port 31 can be aligned or misaligned.

[0129] It should be noted that the main body described above may include other components besides the cooking container, such as an operating platform, heating element, memory, and controller, as detailed above. In some embodiments, the controller may be located inside the operating platform (not shown in the accompanying drawings). Specifically, the controller can be a microcontroller unit (MCU), central processing unit (CPU), microcontroller, graphics processing unit (GPU), a processing chip implemented using a field-programmable gate array (FPGA) or complex programmable logic device (CPLD), etc., and this embodiment does not limit this. The controller can be pre-programmed with corresponding programs to control and implement the control methods, feeding methods, and other logic provided in the embodiments of this application. Besides being located on the main body, the controller can also be located on the feeding device; regardless of its location, the controller can control and implement the control methods, feeding methods, and other logic provided in the embodiments of this application. For details on how to control and implement the control methods, feeding methods, and other logic provided in this application, please refer to the relevant content of the embodiments below, which will not be elaborated here.

[0130] This application embodiment also provides a feeding device, including: a base 30 and a feeding unit 100. The base 30 has a discharge port 31; the feeding unit 100 is movably disposed on the base 30 and can move relative to the base 30, and the feeding unit 100 includes a feeding port 22; during the movement of the feeding unit 100 relative to the base 30, the feeding port 22 and the discharge port 31 can switch between an aligned state and a misaligned state; there is a preset gap between the base 30 and the feeding unit 100, and when the feeding port 22 and the discharge port 31 are in a misaligned state, the discharge port 31 can communicate with the preset gap to form a cleaning channel.

[0131] It should be noted that the feeding device provided in this embodiment has the same structure and function as the feeding device in the cooking equipment of the above embodiments. For details, please refer to the description of the above embodiments, which will not be repeated here.

[0132] In some alternative embodiments, a recess can be provided on the side of the base 30 facing the turntable 20. The surface of this recess is lower than the surface of the material inlet 31 and the feeding port 22 that contact each other. The recess forms a preset gap with the turntable 20. Therefore, when the turntable 20 rotates relative to the base 30, when the feeding port 22 rotates to a position where it is misaligned with the material inlet 31 and is located above the recess of the base 30, cleaning media such as air in the preset gap can be delivered to the material inlet 31 to vent the material inlet 31 and the subsequent conveying pipe 81, so as to deliver the remaining seasonings in the material inlet 31 and the conveying pipe 81 to the cooking container. It is worth noting that when the material inlet 31 has a buffer structure 60, the feeding port 21 is specifically used to be opposite to the buffer cavity 63 of the buffer structure 60, and is in the above-mentioned alignment state. Please refer to the reference again. Figure 4 , Figure 7a , Figure 7b and Figure 11 Furthermore, the cooking equipment also includes a feed pump 84. One end of the feed pipe 81 is connected to the connection port 64. The feed pump 84 is connected to the feed pipe 81 to pump the seasonings in the feed pipe 81 into the cooking container. During operation, the drive unit 83 receives a control command to rotate. A controller can be electrically connected to the drive unit 83 and can be used to control the action of the drive unit 83 according to relevant information. The rotation command is issued by the controller, which can specifically control the rotation angle and direction of the drive unit 83.

[0133] The turntable 20 and the seasoning bottle 11 rotate to the desired seasoning position and align with the feeding port 22. The delivery pump 84 receives a control command and starts, drawing seasoning from the bottle 11 under negative pressure. When the delivery pump 84 draws negative pressure, the valve core of the one-way valve 112 at the outlet 111 of the bottle 11 moves downward, opening the outlet 111. The seasoning in the bottle 11 flows into the buffer chamber 63 through the outlet 111 and is then pumped into the cooking container via the delivery pipe 81. The delivery pump 84 can be a peristaltic pump. Furthermore, the cooking equipment includes a controller electrically connected to the delivery pump 84. The controller controls the delivery pump 84 to pump the seasoning from the delivery pipe 81 into the cooking container. By controlling the operating time of the delivery pump 84, the controller can control the flow rate of the seasoning in the bottle 11, thereby achieving accurate measurement.

[0134] Through creative work, the inventors also discovered that in related technologies, the feeding device is connected to the cooking container via a conveying pipe. When cooking, cooking oil and other seasonings need to be added. In some embodiments, these seasonings are typically liquid, such as salt water, soy sauce, light soy sauce, white vinegar, and aged vinegar. When all seasonings are conveyed through a single pipe, it is very easy for the oil and water to mix, resulting in splattering. To solve the aforementioned specific technical problems, some embodiments of this application provide a cooking device including: a main body 2000 and a feeding device 1000.

[0135] The main body 2000 has a cooking container; the feeding device 1000 includes a seasoning bottle assembly 10 for containing seasonings and a first dispensing port 311 for dispensing seasonings (e.g., Figure 7a , Figure 7b and Figure 12a The material discharge port 311 shown) and the second material discharge port 312 (as shown) Figure 7a , Figure 7b and Figure 12a The material discharge port 312 is shown, along with the first conveying channel and the second conveying channel. Among them, in Figure 7a and Figure 7b From this perspective, the annotations, such as annotations 311(62) and 312(62), refer to the first discharge port 311 and the second discharge port 312 being blocked by the corresponding buffer part 62, respectively. In fact, the first discharge port 311 and the second discharge port 312 are located at the buffer part 62. Among them, the seasonings include at least edible oil and at least one liquid seasoning. It is worth noting that the liquid seasonings described in this embodiment refer to liquid seasonings, such as light soy sauce, dark soy sauce, aged vinegar, salt water, etc., as well as liquid seasonings containing water, such as liquid seasonings made by grinding peppercorns, chili peppers, etc. into powder and mixing them with water.

[0136] The first conveying channel is connected to the first discharge port 311 and the main body 2000, and the second conveying channel is connected to the second discharge port 311 and the main body 2000. Both the first and second conveying channels can convey the aforementioned seasonings to the cooking container. Specifically, the first conveying channel is used to convey liquid seasonings, and the second conveying channel is used to convey edible oil. In this embodiment, the first and second conveying channels are isolated from each other and not connected, allowing edible oil to be conveyed separately from other liquid seasonings.

[0137] In some embodiments, the feeding device 1000 further includes a first feed pump 841 and a second feed pump 842. For example... Figure 7a and Figure 7bAs shown, the first conveying channel includes: a first inlet pipe M1, a first outlet pipe N1, and a first conveying pipe 811. One end of the first inlet pipe M1 is connected to the first discharge port 311, and the other end of the first inlet pipe M1 is connected to the first conveying pump 841. One end of the first outlet pipe N1 is connected to the first conveying pump 841, and the other end of the first outlet pipe N1 is connected to the first conveying pipe M1. The first conveying pipe M1 is connected to the main body 2000. The second conveying channel includes a second inlet pipe M2, a second outlet pipe N2, and a second conveying pipe 812. One end of the second inlet pipe M2 is connected to the second discharge port 312, and the other end of the second inlet pipe M2 is connected to the second conveying pump 842. One end of the second outlet pipe N2 is connected to the second conveying pump 842, and the other end of the second outlet pipe N2 is connected to the second conveying pipe 812. The second conveying pipe 812 is connected to the main body 2000.

[0138] The first conveying pipe 811 and the second conveying pipe 812 are together enclosed within the conveying pipe protective sleeve 813. A preset gap can exist between the first conveying pipe 811 and the second conveying pipe 812, ranging from 5mm to 30mm, preferably 18mm, to ensure a reasonable distance between the two conveying pipes without mutual interference. The first conveying pipe 811, the second conveying pipe 812, and the conveying pipe protective sleeve 813 constitute a connecting pipe for connecting the main body 2000 and the feeding device 1000. Both ends of the connecting pipe are detachably connected to the main body 2000 and the feeding device 1000, respectively. Enclosing the first conveying pipe 811 and the second conveying pipe 812 together with the conveying pipe protective sleeve 813 prevents the piping from becoming messy. Detachably connecting both ends of the connecting pipe to the main body and the feeding device allows for easy replacement of the connecting pipe when it ages or is damaged, and also facilitates disassembly and separate cleaning of the connecting pipe.

[0139] In some embodiments, the first conveying pipe 811 is a flexible pipe. The second conveying pipe 812 is a flexible pipe. The conveying pipe protective sleeve 813 can also be a flexible sleeve. This allows for bending, thereby flexibly arranging the positions of the feeding device 1000 and the main body 2000 within a limited kitchen space. It should be noted that the feeding device includes multiple bottles, which constitute a bottle assembly 10. Specifically, the bottle assembly 10 includes: a first bottle and a second bottle. The second bottle is used to hold cooking oil and can communicate with a second conveying channel so that the seasoning in the second bottle can be conveyed to the cooking container through the second conveying channel. There are multiple first bottles, each used to hold one type of seasoning. For example, there are four second bottles, and the seasoning in each second bottle is different. For example, they may contain a salt and MSG mixed liquid seasoning, a soy sauce and vinegar mixed liquid seasoning, a scallion, ginger and chili mixed liquid seasoning, and water, respectively. Each first bottle can communicate with a first conveying channel so that the seasonings from multiple first bottles can be conveyed through the first conveying channel. It is worth noting that each of the first containers of seasonings is selectively transported, but all are transported through the first conveying channel. In this embodiment, edible oil is transported through one conveying pipe, while other liquid seasonings besides edible oil are transported through another conveying channel. This effectively avoids or improves the phenomenon of oil and water mixing, while also avoiding the problem of a cluttered and complicated layout of the feeding device caused by setting too many conveying pipes, and can also effectively save costs.

[0140] Because a large amount of cooking oil is used when cooking a dish, the volume of the container holding the oil can be large. Other liquid seasonings may include, but are not limited to, at least one of the following: a mixture of salt and MSG, a mixture of soy sauce and vinegar, a mixture of scallions, ginger, and chili peppers, and water. In this embodiment, the cooking oil seasoning is conveyed to the cooking container through the second conveying channel, while other seasonings are conveyed to the cooking container through the first conveying channel. This separates the delivery of cooking oil from other liquid seasonings, preventing the oil from adhering to the sidewalls of the pipes conveying other seasonings and causing oil-water mixing. This effectively avoids or mitigates the splattering phenomenon caused by oil-water mixing. Furthermore, when one of the first containers contains water, the first conveying pump 841 can pump water into the first conveying pipe 811. This allows the pipes and cooking container to be cleaned by pumping water during the addition of other seasonings, thereby improving food safety.

[0141] In this embodiment, the first feed pump 841 and the second feed pump 842 are used to provide the power to suck and transport the seasoning. By controlling the working time of the first feed pump 841 and the second feed pump 842, the output amount of the seasoning can be effectively controlled, and the quantitative dispensing of the seasoning can be achieved.

[0142] In some embodiments, the first feed pump 841 is a stepper pump, and the second feed pump 842 is a DC pump. The DC pump is a conventional pump capable of pumping large quantities of edible oil at a time, thus achieving rapid oil delivery. The stepper pump, on the other hand, can be a high-precision pump, capable of pumping small quantities of seasonings at a time, thus achieving precise seasoning delivery.

[0143] In some embodiments, such as Figure 7a As shown, the feeding device may further include: a base 30, a first feeding pump 841, a second feeding pump 842, a first discharge port 311, and a second discharge port 312 disposed on the base 30; the feeding unit 100 has at least one first feeding port 221 and a second feeding port 222, and the material bottle 11 and the turntable 20 are movably connected to the base 30 and can move relative to each other. The relative movement of the material bottle 11 and the turntable 20 with respect to the base 30 includes, but is not limited to, rotation and linear movement. Figure 10a and Figure 10b The figure shows a feeding unit 100 having four first feeding ports 221, specifically including feeding ports 221b, 221c, 221d, and 221e, and a second feeding port 222 (i.e., the feeding port 222 shown in the figure).

[0144] Please see Figure 7a , Figure 19b and 19d As shown, when the first feeding port 221 is aligned with the first discharge port 311, the first feeding pump 841 starts; when the second feeding port 222 is aligned with the second discharge port 312, the second feeding pump 842 starts. The first feeding port 221 is used to communicate with the first material bottle, and the second feeding port 222 is used to communicate with the second material bottle. The connection between the feeding port and the material bottle means that the seasoning in the material bottle can flow out through the feeding port.

[0145] A first check valve is provided at the first feeding port 221. When the first feed pump 841 starts, it can open the first check valve to connect the first feeding port with the first discharge port 311. A second check valve is provided at the second feeding port 212. When the second feed pump 842 starts, it can open the second check valve to connect the second feeding port with the second discharge port 312. In this embodiment, the first check valve and the second check valve can have the same structure, such as... Figure 6 As shown, the one-way valve has an elastic plunger. Under normal circumstances, the elastic plunger is pressed against the feed port by the spring force, thus closing the feed port. When the feed pump starts, the suction force generated by the feed pump will pull the spring plunger open, thereby connecting the feed port and the discharge port. The way the first feed pump 841 pulls open the first one-way valve can be the same as the way the second feed pump 842 pulls open the second one-way valve.

[0146] Furthermore, the base 30 is also equipped with a drive component 83 (such as...). Figure 7aAs shown, the drive unit 83 is driven by the feeding unit 100 to drive the feeding unit 100 to rotate relative to the base 30. Specifically, the feeding unit 100 includes a bottle assembly 10 and a turntable 20. The drive unit 83 is driven by the turntable 20 to drive the turntable 20 and the bottle assembly 10 mounted on the turntable 20 to rotate, thereby switching the alignment or misalignment of the outlet 111 on the bottle assembly 10 with the discharge port 31 on the base 30. When multiple bottles 11 are provided, the drive unit 83 is used to drive the turntable 20 and the bottle assembly 10 to rotate, thereby switching the alignment of different feeding ports 22 and discharge ports 31. The drive unit 83 may include a motor, and the output shaft of the motor is rotatably connected to the turntable 20. Please refer to the reference. Figure 9 , Figure 10a and Figure 12a The turntable 20 is located above the drive member 83. One connection between the drive member 83 and the turntable 20 is that the drive member 83 includes an output shaft (not shown in the figure), on which a gear 831 is mounted, and the turntable 20 has serrated teeth that mesh with the gear 831. Specifically, the turntable 20 has a receiving groove 272 on the side facing the output shaft. The groove wall of the receiving groove 272 is serrated and meshes with the gear 831. The turntable 20 meshes with the drive member 83 through the receiving groove 272. Alternatively, a separate internal gear is installed in the receiving groove 272 to mesh with the gear 831 on the output shaft.

[0147] Furthermore, the outer surface of the receiving groove 272 forms at least a portion of the partition cavity 21. The outer surface of the receiving groove 272 is provided with a foolproof structure 273, which includes a protrusion 274 and a recess 275. Optionally, the protrusion 274 and the recess 275 are distributed in two different partition cavities 21. In one specific embodiment, the protrusion 274 is distributed in the first partition cavity 21, and the recess 275 is distributed in the second partition cavity 21. The cavity volume of the first partition cavity 21 is larger than that of the second partition cavity 21. The protrusion 274 protrudes inward, reducing the space of the partition cavity 21. Correspondingly, the recess 275 is recessed outward, increasing the space of the partition cavity 21. In addition, the center of the receiving groove 272 is located on the rotation axis of the turntable 20. Furthermore, the center of the receiving groove 272 is also located on the overall central axis of the turntable 20. Thus, the output shaft of the drive component 83 is connected to the center of the turntable 20, ensuring even force distribution and smoother rotation. Another connection method between the drive component 83 and the turntable 20 is to have a socket on the turntable 20, with the output shaft of the drive component 83 engaging with this socket. Pins are also provided to pass through both the turntable 20 and the output shaft to prevent disengagement. Yet another connection method involves the output shaft of the drive component 83 being splined, with corresponding mating holes on the turntable 20 for engagement with the spline.

[0148] Please refer to the reference. Figure 4 and Figure 7a In one embodiment, the drive element 83 is mounted on the base 30. To avoid the drive element 83 being exposed, it is installed inside the base 30. Optionally, the drive element 83 is located at the center of the base 30, and the output shaft of the drive element 83 is driven and connected to the middle of the turntable 20, that is, the rotation axis of the turntable 20 passes through the central axis of the base 30. Figure 7a and Figure 7b As shown, the first feed pump 841, the drive unit 83, and the second feed pump 842 can be arranged along the radial direction of the base 30. Specifically, the included angle between the first feed pump 841, the drive unit 83, and the second feed pump 842 in the plane can be approximately 180°, or the angle between the three can be 180°±5°. Since the three are arranged along the radial direction of the base 30, the space occupied in the vertical direction is reduced, and the height of the base 30 is lowered. Furthermore, the first feed pump 841 and the second feed pump 842 can be symmetrically arranged on both sides of the drive unit 83, so that the weight on both sides of the base 30 is as equal as possible, and the force is as balanced as possible. In this way, during the rotation of the turntable 20 driven by the drive unit 83, the phenomenon of vibration and abnormal noise caused by uneven weight distribution on both sides of the base 30 is avoided or improved.

[0149] This application embodiment also provides a feeding device for cooperating with a main body having a cooking container, comprising: a feeding device 1000 for containing seasonings, including a seasoning bottle assembly 10 for containing seasonings, a first discharge port 311, a second discharge port 312, a first conveying channel, and a second conveying channel for discharging seasonings; wherein the seasonings include at least edible oil and at least one liquid seasoning; the first conveying channel is connected to the first discharge port 311, and the second conveying channel is connected to the second discharge port 312, and the first and second conveying channels are capable of conveying seasonings to the cooking container; wherein the first conveying channel is used to convey liquid seasonings, and the second conveying channel is used to convey edible oil. It is worth noting that when the discharge port 31 has a buffer structure 60, the buffer cavity 63 of the buffer structure 60 constitutes the discharge port 31, and when the feeding port 21 is aligned with the buffer cavity 63 of the buffer structure 60, the conveying pump 84 is activated. It should be noted that the structure and function of the feeding device provided in this application embodiment are the same as those of the feeding device in the cooking equipment of the above embodiment. For details, please refer to the description of the above embodiment, which will not be repeated here.

[0150] This application embodiment also provides another cooking device, including: a main body 2000 with a cooking container 201; a feeding device 1000 for containing seasonings, and the feeding device 1000 includes a first conveying channel and a second conveying channel; wherein the seasonings include at least edible oil and at least one liquid seasoning. The first conveying channel connects the feeding device 1000 and the main body 2000, and the second conveying channel connects the feeding device and the main body 2000, so that the seasonings can be conveyed to the cooking container through the first and second conveying channels; wherein the first conveying channel is used to convey liquid seasonings, and the second conveying channel is used to convey edible oil. The cooking device in this embodiment is basically the same as the cooking device with two conveying channels described above, except that this embodiment does not limit the specific structure of the feeding device 1000, as long as it has two conveying channels to convey edible oil and other liquid seasonings respectively.

[0151] This application embodiment also provides a feeding device 1000 for cooperating with a main body 2000 having a cooking container. The feeding device 1000 is used to hold seasonings and includes a first conveying channel and a second conveying channel. The seasonings include at least edible oil and at least one liquid seasoning, and the seasonings can be conveyed to the cooking container through the first and second conveying channels. The first conveying channel is used to convey liquid seasonings, and the second conveying channel is used to convey edible oil. It should be noted that the structure and function of the feeding device provided in this embodiment are the same as those in the cooking equipment of the above embodiments. For details, please refer to the description of the above embodiments, which will not be repeated here.

[0152] Other embodiments of this application also provide a material conveying assembly 80 for connecting a first body and a second body. The first and second bodies can be any device that needs to convey gaseous, liquid, or even solid media. The material conveying assembly 80 includes: a first material conveying pipe 811, a second material conveying pipe 812, and a material conveying pipe protective sleeve 813; the second material conveying pipe 812 can be arranged parallel to the first material conveying pipe 811; the material conveying pipe protective sleeve 813 encloses both the first material conveying pipe 811 and the second material conveying pipe 812.

[0153] In addition, for the cooking equipment provided in this application embodiment, in order to facilitate the overall storage of the ingredient feeding unit 100, such as Figure 2 As shown, the cooking device further includes a housing 400 (e.g., Figure 1bAs shown, the housing 400 is connected to the base 30, together forming an inner cavity, in which the feeding unit 100 is at least partially located. Specifically, one end of the housing 400 is open, and the base 30 covers the opening of the housing 400. In this embodiment, the housing 400 can be formed by combining multiple structures, for example, by combining multiple structures arranged along the height direction, or by splicing multiple structures arranged along the width direction. Of course, the housing 400 can be a complete outer shell structure to reduce assembly steps. The shape of the housing 400 includes, but is not limited to, cylindrical, square, or hemispherical. In a preferred embodiment, the housing 400 is cylindrical to facilitate the rotation of the internal feeding unit 400 relative to it.

[0154] In some embodiments of this application, the housing 400 includes an outer barrel 40 and a middle barrel 50, which are connected to form an inner cavity, and the feeding unit 100 is at least partially located in the inner cavity. In some specific embodiments, the outer barrel 40, the middle barrel 50, and the base 30 are stacked sequentially along the height direction to jointly form the inner cavity, and the base 30 closes one end of the middle barrel 50. The turntable 20 of the feeding unit 100 is located in the inner cavity, and the turntable 20 is located on the side of the bottle assembly 10 facing the base 30. The bottle assembly 10 is at least partially located in the inner cavity and is mounted on the turntable 20. "The bottle assembly 10 is at least partially located in the inner cavity" means that the bottle assembly 10 can be partially exposed outside the inner cavity; for example, the top of the bottle assembly 10 can extend from the outer barrel 40. Of course, the bottle assembly 10 can also be entirely located in the inner cavity.

[0155] In this embodiment, the outer barrel 40 and the middle barrel 50 together surround the turntable 20 and the bottle assembly 10. When the drive component 83 drives the turntable 20 and the bottle assembly 10 to rotate, the turntable 20 and the bottle assembly 10 rotate relative to the outer barrel 40 and the middle barrel 50. The outer barrel 40 and the middle barrel 50 can enclose multiple bottle assemblies 10 and the turntable 20, preventing interference between external objects and the rotating parts. Simultaneously, the space enclosed by the outer barrel 40 and the middle barrel 50 protects the rotating parts. The entire structure is equivalent to forming an inner and outer layer structure. Both the inner and outer layers are distributed vertically. The inner layer consists of the vertically distributed bottle assembly 10, turntable 20, and drive component 83, while the outer layer consists of the vertically distributed outer barrel 40, middle barrel 50, and base 30. The overall structure is compact and rationally laid out. This avoids the situation where a completely inner-outer distribution would result in excessive width, or a completely vertical distribution would result in excessive height.

[0156] In one embodiment, the outer barrel 40 is closed at one end and open at the other. The two ends of the middle barrel 50 are open, with one end of the middle barrel 50 connected to the open end of the outer barrel 40 and covering the top of the turntable 20. The turntable 20 is located inside the middle barrel 50, and the other end of the middle barrel 50 also covers the base 30. In this embodiment, the bottle assembly 10 and the turntable 20 are all located within the space formed by the outer barrel 40 and the middle barrel 50, avoiding collisions with external objects. Simultaneously, the outer barrel 40 has a closed end, enclosing the bottle assembly 10 inside, preventing it from being exposed and also preventing foreign objects from falling into the bottle assembly 10. For example, it prevents dust accumulation and oil fumes from adhering to the bottle assembly 10, ensuring its cleanliness. Please refer to the references. Figure 6 In this embodiment, the outer tub 40 and the middle tub 50 are interconnected. One possible connection method is that the outer tub 40 is equipped with a first magnetic chuck 41, and the middle tub 50 is equipped with a second magnetic chuck 51. The outer tub 40 and the middle tub 50 are magnetically connected through the first magnetic chuck 41 and the second magnetic chuck 51. One of the first magnetic chuck 41 and the second magnetic chuck 51 can be a magnet, and the other can be a metal block; of course, both the first magnetic chuck 41 and the second magnetic chuck 51 can be magnets. This magnetic connection allows for quick assembly and disassembly of the outer tub 40 and the middle tub 50, making the process simple and efficient. Furthermore, the magnetic connection is detachable, facilitating the separation of the outer tub 40 and the middle tub 50. Please refer to the references. Figure 6 and Figure 14 Furthermore, to facilitate the installation of the second magnetic component 51, a mounting groove 54 is formed on the end face of the middle barrel 50, and the second magnetic component 51 is accommodated in the mounting groove 54. The mounting groove 54 provides a positioning effect for the second magnetic component 51, and reduces or even eliminates the possibility of the second magnetic component 51 protruding from the end face of the middle barrel 50, preventing external structures from colliding with the second magnetic component 51 and affecting the connection stability between the second magnetic component 51 and the middle barrel 50. One way to fix the second magnetic component 51 to the middle barrel 50 is that the middle barrel 50 is a plastic part, and the second magnetic component 51 is integrally injection molded with the middle barrel 50 as an insert, effectively preventing them from detaching. Another possible fixing method is that the second magnetic component 51 is embedded in the mounting groove 54 on the middle barrel 50 for a tight fit. Similarly, a groove can also be provided at the bottom of the outer barrel 40 for the first magnetic component 41 to be installed. The first magnetic attractor 41 can extend in a ring around the circumference of the outer tub 40. Alternatively, the first magnetic attractor 41 can be in a block shape. To improve the magnetic attraction effect, the outer tub 40 can be provided with multiple first magnetic attractors 41, which are spaced apart along the circumference of the outer tub 40. Similarly, the second magnetic attractor 51 can extend in a ring around the circumference of the middle tub 50. Alternatively, the second magnetic attractor 51 can be in a block shape. To improve the magnetic attraction effect, the middle tub 50 can be provided with multiple second magnetic attractors 51, which are spaced apart along the circumference of the outer tub 40.

[0157] In this embodiment, the middle bucket 50 is connected to the base 30, that is, the upper end of the middle bucket 50 is connected to the outer bucket 40, and the lower end of the middle bucket 50 is connected to the base 30. For ease of assembly and disassembly, the middle bucket 50 and the base 30 are detachably connected. There are several ways to connect the middle bucket 50 and the base 30. One possible method is that the side of the base 30 is provided with a limiting groove 36, the inner wall of the middle bucket 50 has a limiting rib 55, the middle bucket 50 is fitted onto the outer side of the base 30, and the limiting rib 55 is slid into the limiting groove 36 and secured by rotating it at a preset angle. The limiting groove 36 has a sliding entrance for the limiting rib 55 to slide into, and the opening direction of this sliding entrance is along the circumference of the base 30. Please refer to Figure 12 and... Figure 14 Specifically, a first baffle 33 is provided on the side of the base 30, extending circumferentially along the base 30. A limiting rib 55 abuts against the side of the first baffle 33 opposite to the outer tub 40, thereby preventing the middle tub 50 from detaching from the base 30 in the direction of the outer tub 40. Optionally, the first baffle 33 is provided with a positioning protrusion 35, and the limiting rib 55 is provided with a positioning groove 56 that cooperates with the positioning protrusion 35, thereby restricting the rotation of the middle tub 50 relative to the base 30. Furthermore, a second baffle 34 is also provided on the side of the base 30, connected to one end of the first baffle 33 and protruding from the side of the first baffle 33 opposite to the outer tub 40. The limiting rib 55 can abut against the second baffle 34 to restrict the middle tub 50 from continuing to rotate relative to the base 30. Optionally, the base 30 has a small end 37 and a large end 38 connected to each other, a first baffle 33 and a second baffle 34 are disposed at the small end 37, and a limiting groove 36 is formed between the end faces of the first baffle 33 and the large end 38. During installation, first, place the middle barrel 50 on the outside of the base 30, with the limiting rib 55 misaligned with the first stop rib 33. Then, rotate the middle barrel 50 so that the limiting rib 55 slides into the limiting groove 36 until the end of the limiting rib 55 abuts against the second stop rib 34. Simultaneously, the positioning protrusion 35 engages with the positioning groove 56, thus stopping the rotation of the middle barrel 50. At this point, the upper end of the limiting rib 55 abuts against the lower end of the first stop rib 33, restricting the middle barrel 50 from moving upwards, while the lower end of the limiting rib 55 abuts against the end face of the large end 38 of the base 30, restricting the middle barrel 50 from moving downwards. The end of the limiting rib 55 abuts against the second stop rib 34, restricting the middle barrel 50 from continuing to rotate. The positioning groove 56 on the limiting rib 55 engages with the positioning protrusion 35 on the first stop rib 33, simultaneously restricting the middle barrel 50 from rotating clockwise or counterclockwise. Please refer to the reference again. Figure 6To prevent the turntable 20 from detaching from the middle drum 50 and entering the outer drum 40, a further abutment rib 52 is provided on the inner peripheral wall of the middle drum 50. The abutment rib 52 abuts against the end of the turntable 20 facing the outer drum 40, thereby preventing vertical movement of the turntable 20 during rotation. In one embodiment, a protrusion 53 is provided at the end of the abutment rib 52, which protrudes towards the side where the outer drum 40 is located. Thus, the abutment rib 52, the protrusion 53, and the inner wall of the middle drum 50 together form the mounting groove 54. Of course, in other embodiments, the mounting groove 54 can also be directly formed on the end face of the middle drum 50. Since the turntable 20 needs to rotate relative to the middle drum 50, in order to reduce the friction between the turntable 20 and the middle drum 50 and ensure that the turntable 20 can rotate smoothly, in one embodiment, a plurality of elastic support columns 28 are provided on the end face of the turntable 20 facing the outer drum 40. The plurality of elastic support columns 28 are circumferentially spaced along the rotation direction of the turntable 20; the abutment rib 52 abuts against the elastic support columns 28. In this embodiment, the turntable 20 abuts against the abutment rib 52 on the middle drum 50 through the elastic support columns 28. On the one hand, the elastic support columns 28 adapt to the compression during the rotation of the turntable 20 through elastic deformation, preventing the turntable 20 from jamming or interfering with the middle drum 50; on the other hand, the elastic support columns 28 change the contact between the turntable 20 and the abutment rib 52 from surface contact to point contact, reducing the contact area and the frictional resistance, thus facilitating the flexible rotation of the turntable 20 relative to the middle drum 50.

[0158] In another embodiment, the end face of the turntable 20 facing the outer barrel 40 is provided with a plurality of circumferentially distributed small rollers. These small rollers assist the turntable 20 in rotating relative to the middle barrel 50, reducing friction. Please refer to the reference again. Figure 5 Furthermore, to ensure smoother rotation of the turntable 20, a rolling element 29 is provided between the turntable 20 and the base 30, allowing the turntable 20 to be rotatably connected to the base 30 via the rolling element 29. The rolling element 29 includes, but is not limited to, balls, rollers, and cylinders. The rolling element 29 can be provided on one of the turntable 20 and the base 30, or on both the turntable 20 and the base 30. The rolling element 29 reduces friction between the turntable 20 and the base 30, resulting in smoother rotation of the turntable 20, reduced wear on both the turntable 20 and the base 30, and extended service life.

[0159] In one embodiment, the drive unit 83 is located at the center of the base 30, the output shaft of the drive unit 83 is driven and connected to the middle of the turntable 20, the feed pump 84 is located on the side of the drive unit 83, and the feed pipe 81 passes through the side of the base 30. In this embodiment, the drive unit 83, the feed pump 84, and the feed pipe 81 are all concentrated in the base 30 and arranged laterally, thereby reducing the space occupied in the vertical direction and lowering the height of the base 30. In addition, the bottle assembly 10 and the turntable 20 are located inside the middle barrel 50 and the outer barrel 40, and the drive unit 83 is located inside the base 30, which is equivalent to forming an inner and outer two-layer structure. The outer barrel 40, the middle barrel 50, and the base 30 are arranged vertically, while the inner bottle assembly 10, the turntable 20, and the drive unit 83 are also arranged vertically. This avoids the problem of excessive overall height caused by the entire structure being arranged vertically, and also avoids the problem of excessive lateral size caused by the entire structure being set up inside and outside. In addition, the arrangement of the seasoning bottle 11, the turntable 20 and the base 30 vertically makes it easier for the seasoning in the seasoning bottle 11 to flow out of the seasoning bottle 11, making the discharge from the seasoning bottle 11 cleaner and preventing the seasoning from flowing back, thus reducing the occurrence of cross-contamination of flavors.

[0160] This application also proposes a feeding device, which includes a feeding unit 100. The specific structure of the feeding unit 100 is described in the above embodiments and will not be repeated here. Furthermore, the feeding device also includes a buffer structure 60. The specific structure of the buffer structure 60 is also described in the above embodiments and will not be repeated here.

[0161] The following describes the method embodiments provided in this application. The methods provided in the following embodiments of this application can be applied to, for example... Figure 1a The illustrated cooking application scenario includes a main unit 2000 and a feeding device 1000 communicatively connected to the main unit 2000. For details regarding the main unit 2000 and the feeding device 1000, please refer to the relevant content of the above embodiments; further details will not be provided here.

[0162] In specific implementation, the method execution entity provided in each embodiment of this application is the controller described above. This controller can be located on the feeding device 1000 or the main body 2000; or it can be combined on both the feeding device 1000 and the main body 2000. Specifically, a main controller can be located on the main body 2000, and a slave controller can be located on the feeding device 1000. The two cooperate to complete the method logic provided in each embodiment of this application. Based on Figure 1aIn the illustrated application scenarios, when the controller executing the methods provided in the embodiments of this application is located in the main unit 2000, the controller can determine the corresponding data information of the required seasonings based on the digital recipe selected by the user, and control the turntable on the feeding device to rotate according to the required seasoning data information to execute the seasoning addition task corresponding to the recipe; simultaneously, it can also control the spatula assembly to stir the ingredients to execute the cooking task corresponding to the digital recipe. When the controller executing the methods provided in the embodiments of this application is located in the feeding device 1000, the controller controls the turntable on the feeding device to rotate according to the required seasoning data received from the main unit 2000 to execute the automatic seasoning addition task corresponding to the recipe.

[0163] Figure 20 shows a schematic flowchart of a control method provided in an embodiment of this application. This control method can be applied to, for example... Figure 1a The cooking equipment is shown. (See Figures 20 to 20) Figure 24 As shown, the control method includes the following steps:

[0164] 101. Control the first drive unit to rotate so as to align the outlet of the target seasoning bottle with the target discharge port;

[0165] 102. Control the second drive unit corresponding to the target discharge port to operate, so that the target seasoning is added into the cooking container through the target discharge port and the conveying pipe corresponding to the target discharge port;

[0166] 103. Control the first drive unit to continue operating, so that the outlet of the target seasoning corresponding to the bottle is misaligned with the target discharge port, and external air enters the target discharge port;

[0167] 104. Control the second drive unit to continue operating, so as to purge the residual target seasoning in the conveying pipe with the external air.

[0168] For specific implementation details, please refer to [link / reference]. Figure 1a , Figure 2 and Figures 7a to 7bAs shown, the first driving unit mentioned in 101 to 104 above may refer to the driving component 83 installed in the cooking device. Specifically, the driving component 83 may be installed inside the base 30 of the feeding device 1000. The base 30 is rotatably connected to the turntable 20 through the driving component 83. The base 30 is provided with multiple discharge ports 31. When the driving component 83 is rotated, it can drive the turntable 20 to rotate, thereby driving the material bottle 11 inserted on the turntable 20 to move, so that the discharge port of the material bottle 11 is aligned with the corresponding discharge port 31. The second drive unit refers to the feed pump 84 installed in the cooking equipment, with one feed pump 84 corresponding to one discharge port 31. When the discharge port of a container 11 is aligned with the corresponding discharge port 31, the feed pump 84 is activated. The operation of the feed pump 84 creates a negative pressure in the space corresponding to the discharge port 31. Due to the negative pressure, the one-way valve at the discharge port of the container 11 can be opened, allowing the seasoning in the container 11 to be added to the cooking container through the discharge port 31 and the corresponding feed pipe. When the discharge port of a container 11 is misaligned with the corresponding discharge port 31, because there is a gap between the discharge port 31 and the bottom of the turntable 20, external air can enter the discharge port 31 through this gap. In this state, the operation of the feed pump 84 can drive the circulation of external air. Driven by the external airflow, the remaining seasoning in the discharge port 31 and the feed pipe can be emptied. For a detailed description of the drive unit 83 and the feed pump 84, please refer to the relevant content in the above embodiments, which will not be repeated here.

[0169] In one feasible technical solution, the aforementioned 101 "controlling the first driving unit to rotate, so as to drive the outlet of the target seasoning corresponding to the bottle to align with the target discharge port" can specifically include:

[0170] 1011. Obtain relevant information about the target seasoning;

[0171] 1012. Based on the aforementioned information, control the first driving unit to rotate so as to align the outlet of the target seasoning corresponding to the bottle with the target discharge port.

[0172] In practical applications, in a specific application scenario, such as Figure 1a In the cooking application scenarios shown, the main unit 2000 or terminal devices (such as smartphones, tablets, personal computers, etc., not shown in the figure) that are communicatively connected to the main unit 2000 generally have pre-installed digital recipes for users to select the digital recipes of the dishes they wish to cook. For example, Figure 1aThe main unit 2000 shown has pre-installed digital recipes. Users can trigger corresponding operations on the digital recipes through the interactive interface provided by the main unit 2000 to select the digital recipe for the dish they wish to cook. The interactive interface can be located on the base 22 of the cooking device; alternatively, if the user's terminal device has an app corresponding to the cooking device installed, and this app is connected to the main unit 2000, the user can also select the digital recipe for the dish they wish to cook from the digital recipes through the interactive interface provided by the corresponding app. The digital recipes contain information on the required ingredients, seasonings, and other ingredients for the dish. In response to the user's selection, the main unit 2000 not only obtains the digital recipe for the dish the user wishes to cook, but also acquires data such as the steps required for cooking and the information on added seasonings. The main unit 2000 can determine the relevant information of the target seasoning to be added based on the acquired data content corresponding to the dish being cooked, and can send the relevant information of the target seasoning to the adding device 1000 via wireless communication (such as Bluetooth), so that the controller in the adding device 1000 can execute the adding control logic in steps 101 to 104 above based on the received relevant information of the target seasoning. Based on the above description, that is, the relevant information of the target seasoning in step 1011 can be obtained by the controller from the main unit 20. Specifically, the main unit 2000 can obtain the relevant information of the target seasoning in the following way: in response to a selection operation triggered by the user through the interactive interface, it obtains the data content corresponding to the dish the user wants to cook based on the selection operation; and determines the relevant information of the target seasoning based on the data content.

[0173] The relevant information of the aforementioned target seasoning may include, but is not limited to: seasoning label, seasoning category, required amount of seasoning, and seasoning dispensing time. The seasoning label includes at least one of the following: seasoning name, bottle name; the seasoning category includes at least one of the following: mixed liquid seasoning, oil-based seasoning, water, etc.; the required amount of seasoning includes at least one of the following: weight, volume; the seasoning dispensing time includes at least one of the following: start time of dispensing, end time of dispensing, and duration of the dispensing process, etc. Furthermore, when there are multiple target seasonings, the relevant information may also include the priority order of adding the multiple target seasonings, so that the dispensing control logic provided in this embodiment can be executed sequentially for each of the multiple target seasonings according to their priority order. After obtaining the relevant information of the target seasoning, it is then possible to determine the target dispensing port and the bottle containing the target seasoning based on pre-stored data in the memory. For example, based on the obtained category of the target seasoning, the target seasoning can be selected from multiple dispensing ports on the turntable by combining the pre-stored correspondence between the dispensing ports and seasoning categories. Alternatively, based on the obtained identifier of the target seasoning, the corresponding bottle can be determined by combining the stored seasoning information of multiple bottles. Based on the determined bottle and target dispensing port corresponding to the target seasoning, and combined with pre-stored data (such as the correspondence between bottles and dispensing ports, the relative positions of multiple dispensing ports, etc.), it is possible to control the rotation of the turntable to move the bottle corresponding to the target seasoning, aligning the dispensing port of the bottle with the target dispensing port, thereby enabling the target seasoning to be dispensed through the target dispensing port.
