[0032] The present invention will be described in further detail below based on the accompanying drawings and implementation examples.

[0033] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0034] Implementation Case 1:

[0035] A feeding unit, refer to Figure 1-8 as well as Figure 9 , which is arranged on the pot cover 9 and is used to put seasoning into the pot, and includes a box body 1, a shell 2, a feeding push rod 3, and a driving mechanism. The box body 1 is a hollow structure, and the box body 1 serves as a container. The shell 2 and the driving mechanism are both arranged inside the box body 1. The shell 2 is a hollow structure, and the cavity inside it is used to accommodate seasoning. It has a feed port 2a on the top and a discharge port 2b on the bottom. The top of the box body 1 is provided with a feeding port 1a at the position corresponding to the feeding port 2a. The bottom of the box body 1 and the bottom of the shell 2 are integrally connected, that is, the discharge cavity is formed at the bottom of the box body 1. The user can add seasoning to the box body 1 through the feeding port 1a, and the seasoning then enters the cavity of the shell 2 from the feeding port 2a, and is then put into the pot from the discharge port 2b.

[0036] In this embodiment, the feeding push rod 3 is vertically slidably arranged in the shell 2 and is driven by a driving mechanism, so that the feeding push rod 3 can slide in both directions vertically. A blocking structure 4 is provided at the bottom end of the feeding push rod 3. The blocking structure 4 has two states. One state is a first state in which the discharge port 2b is blocked. When the blocking structure 4 is in the first state, the seasoning is confined in the cavity of the shell 2; the other state is a second state in which the discharge port 2b is opened. When the blocking structure 4 is in the second state, the seasoning in the shell 2 can be put into the pot through the discharge port 2b. The vertical sliding of the feeding push rod 3 can switch the blocking structure 4 between the first state and the second state, that is, the feeding push rod 3 is driven to move vertically by the driving mechanism, so that the feeding unit completes the feeding of seasonings into the pot.

[0037] In this embodiment, by setting two states of the sealing structure 4, in the first state, blocking the feed port 2a can prevent the seasoning from leaking into the pot, and can also prevent the steam in the pot from entering the shell 2 and causing the seasoning to get damp, while in the second state, the seasoning can be put into the pot through the feed port 2a; by adjusting the state of the sealing structure 4 between the first state and the second state through the vertical sliding of the feeding push rod 3, the seasoning can be quickly put into the pot, completing automatic feeding, which is more convenient for users to use.

[0038] In this embodiment, the sealing structure 4 includes a first sealing head 41 and a second sealing head 42 spaced apart from each other from bottom to top. When the first sealing head 41 and the second sealing head 42 are located at the feed port 2a, they can block the feed port 2a, which corresponds to the first state of the sealing structure 4. When the first sealing head 41 is located below the discharge port 2b and the second sealing head 42 is located above the feed port 2a, the discharge port 2b is opened, which corresponds to the second state of the sealing structure 4.

[0039] In this embodiment, the feeding push rod 3 is limited to a movement stroke, which has a highest position and a lowest position. When the feeding push rod 3 is in the highest position, the first blocking head 41 blocks the discharge port 2b, that is, the blocking structure 4 is in the first state; when the feeding push rod 3 is in the lowest position, the second blocking head 42 blocks the discharge port 2b, that is, the blocking structure 4 is in the first state; when the feeding push rod 3 slides downward from the highest position to the lowest position, the blocking structure 4 gradually switches from the first state to the second state, that is, the discharge port 2b is opened, and then gradually switches to the first state. During this process, the seasoning is fed into the pot from the discharge port 2b. When the feeding push rod 3 slides upward from the lowest position to the highest position, the blocking structure 4 switches from the first state to the second state and then to the first state. The entire process of the feeding push rod 3 sliding downward from the highest position to the lowest position and then sliding upward to the highest position completes a feeding action of the seasoning.

[0040] In this embodiment, the diameter of the feeding push rod 3 is smaller than the diameter of the discharge port 2b, and the first plugging head 41 is connected to the bottom end of the feeding push rod 3. The first plugging head 41 can also be connected to the rod body of the feeding push rod 3, and the second plugging head 42 is connected to the rod body of the feeding push rod 3. When the feeding push rod 3 slides downward from the highest position, and the first plugging head 41 is located below the feeding port 2a and the second plugging head 42 is located above the feeding port 2a, the feeding push rod 3 is exactly located at the feeding port 2a. Since the diameter of the feeding push rod 3 is smaller than the discharge port 2b, a gap is formed between the discharge port 2b and the discharge port 2b, allowing the seasoning to fall, thereby allowing the seasoning to be dropped into the pot.

[0041] In this embodiment, the first plugging head 41 and the second plugging head 42 can block the discharge port 2b. The diameter of the first plugging head 41 and the second plugging head 42 is larger than the feeding push rod 3. When the feeding push rod 3 slides downward from the highest position to the lowest position, the second plugging head 42 pushes down the seasoning located between the first plugging head 41 and the second plugging head 42, thereby pushing the seasoning between the first plugging head 41 and the second plugging head 42 downward out of the discharge port 2b. The seasoning put into the pot is basically the seasoning between the first plugging head 41 and the second plugging head 42, that is, the amount put in is a fixed amount. When the feeding push rod 3 slides upward from the lowest position to the highest position, since the discharge port 2b is opened for an extremely short time, basically no seasoning will fall from the discharge port 2b. Therefore, the amount of seasoning put in by one feeding action is fixed, thereby enabling accurate feeding of the seasoning. The user can perform several feeding actions through the driving mechanism according to the required amount of seasoning.

[0042] In this embodiment, the discharge port 2b is defined by the upper hole wall h1 and the lower hole wall h2. There is a gap between the upper hole wall h1 and the outer peripheral surface of the second plugging head 42, and there is no gap between the lower hole wall h2 and the outer peripheral surface of the second plugging head 42. The amount of seasoning released in each feeding action is fixed, that is, basically the amount between the first plugging head 41 and the second plugging head 42. In addition, the time when the discharge port 2b is opened in the process of sliding from the highest position to the lowest position is extremely short, but a very small amount of steam will still enter the shell 2 through the discharge port 2b. After long-term use, it is bound to cause the seasoning in the shell 2 to become damp. Since only a very small amount of steam will enter the shell 2 during each feeding process, it can only affect the seasoning in the shell 2 near the discharge port 2b. When the feeding push rod 3 slides upward from the lowest position to the highest position, a very small amount of seasoning affected by steam can pass through the gap between the upper hole wall h1 and the outer peripheral surface of the second sealing head 42 and fall out of the discharge port 2b, thereby preventing this part from being affected by moisture and affecting the dry environment inside the shell 2.

[0043] In this embodiment, the upper hole wall h1 gradually retracts from top to bottom until it reaches the bottom edge of the upper hole wall h1, so that the upper hole wall h1 forms a slope structure, so that a very small amount of damp seasoning can quickly slide down along the upper hole wall h1 and fall out of the discharge port 2b.

[0044] In this embodiment, when the feeding push rod 3 is in the highest position, the top edge of the outer peripheral surface of the second plugging head 42 is higher than the bottom edge of the lower hole wall h2, so that the outer peripheral surface of the second plugging head 42 and the upper hole wall h1 form a collecting groove c, and a very small amount of damp seasoning can be temporarily collected in the collecting groove c. When the feeding push rod 3 slides upward from the lowest position, the very small amount of damp seasoning collected in the collecting groove c can fall quickly.

[0045] In this embodiment, the axis of the feeding push rod 3 corresponds to the center of the discharge port 2b. The first and second plugging heads 41, 42 extend outward around the feeding push rod 3, forming a disc-shaped structure. Because the axis of the feeding push rod 3 corresponds to the center of the discharge port 2b, the seasonings added are evenly distributed around the circumference, ensuring a more dispersed and even distribution of the seasonings into the pot. This prevents the dish from having a strong flavor in some parts while being too bland in others, which can affect the quality of the dish.

[0046] In this embodiment, the bottom surface of the second plugging head 42 is set to be a plane, so that during the feeding process, the second plugging head 42 pushes the seasoning downward in a vertical downward direction, so that the seasoning between the first plugging head 41 and the second plugging head 42 can be quickly pushed down to the discharge port 2b, which is conducive to the feeding of the seasoning into the pot. The top surface of the first plugging head 41 is set to be tilted downward from the connection to the feeding push rod 3 to its outer periphery, so that the top surface of the first plugging head 41 presents a slope structure. During the feeding process, the seasoning can quickly spread outward along the top surface of the first plugging head 41, which can expand the feeding range of the seasoning into the pot and make the distribution of the seasoning more uniform, further improving the cooking quality of the dish; in addition, it can also prevent the seasoning from accumulating on the top surface of the first plugging head 41, making the feeding amount of the seasoning more accurate.

[0047] In this embodiment, the drive mechanism is disposed within the box body 1 and located outside the housing 2. The drive mechanism includes a driver 51, a transverse push rod 52, and a transmission assembly. The transverse push rod 52 is driven by the driver 51 to move back and forth laterally. The transmission assembly drives the transverse push rod 52 and the feeding push rod 3, converting the transverse movement of the transverse push rod 52 into vertical movement of the feeding push rod 3. Therefore, when the driver 51 drives the transverse push rod 52 to move, the transmission assembly drives the feeding push rod 3 to slide vertically, causing the blocking structure 4 to block the feed port 2a or open the discharge port 2b, thereby allowing the seasoning to be fed.

[0048] In this embodiment, the seasoning added to the pot is primarily contained between the first and second sealing heads 41, 42. This means that the feeding amount per reciprocating movement of the feeding push rod 3 in each feeding unit is a constant. The feeding amount per feeding unit is a, and the user's desired feeding amount is b. Based on the desired feeding amount b, the number of feedings per unit is determined as n, where n = b / a. The driving mechanism controls the feeding push rod to slide back and forth n times to complete the feeding process, achieving precise control of the feeding amount.

[0049] In this embodiment, by setting a horizontal push rod 52 and a transmission assembly, the horizontal movement of the horizontal push rod 52 can be converted into the vertical movement of the feeding push rod 33. On the one hand, the vertical sliding of the feeding push rod 3 can be easily and efficiently realized, so that the seasoning can be accurately fed; on the other hand, the movement direction of the horizontal push rod 52 of the driving mechanism is horizontal, so that the space occupied by the driving mechanism in the vertical space is relatively small, and the height of the feeding unit can be compressed; since the feeding unit is placed on the pot cover when in use, it can avoid the feeding unit from shaking or even falling during use.

[0050] In this embodiment, the driving mechanism drives the feeding push rod 3 in such a way that the driver 51 drives the horizontal push rod 52 to move horizontally, thereby causing the feeding push rod 3 to slide vertically downward and move from the highest position to the lowest position. The feeding push rod 3 is provided with an elastic return member 31, which is used to drive the feeding push rod 3 to reset, that is, to slide vertically upward from the lowest position to the highest position.

[0051] For the specific structure of the driving mechanism, refer to Figure 3 In the first embodiment, the transmission assembly includes a first transmission block 531 arranged at one end of the horizontal push rod 52; the first transmission block 531 has a first mating surface inclined to the horizontal direction and the vertical direction, and the top end of the feeding push rod 3 can slide on the first mating surface of the first transmission block 531.

[0052] Reference Figure 4 In the second embodiment, the transmission assembly includes a second transmission block 532 arranged at the top of the feeding push rod 3; the second transmission block 532 has a second mating surface inclined to the horizontal direction and the vertical direction, and one end of the transverse push rod 52 can slide on the second mating surface of the second transmission block 532.

[0053] Reference Figure 5 In the third embodiment, the transmission assembly includes a first transmission block 531 arranged at one end of the horizontal push rod 52 and a second transmission block 532 arranged at the top of the feeding push rod 3; the first transmission block 531 has a first mating surface inclined to the horizontal direction and the vertical direction, and the second transmission block 532 has a second mating surface inclined to the horizontal direction and the vertical direction. The first mating surface can be in contact with the second mating surface and slide relative to each other.

[0054] The above three embodiments are all capable of converting the lateral movement of the transverse push rod 52 into the vertical movement of the feeding push rod 3, and the structural design suggests that the required layout space is small.

[0055] In this embodiment, a vertically extending guide sleeve 21 is provided within the housing 2. The guide sleeve 21 is connected to the top of the housing 2 and is slidably sleeved on the feeding push rod 3. The guide sleeve 21 guides the feeding push rod 3, preventing the feeding push rod 3 from radially deflecting or misaligning, thereby ensuring that the blocking structure 4 can align with the discharge port 2b during its vertical sliding process to block or open the discharge port 2b.

[0056] In this embodiment, the guide sleeve 21 has an inwardly concave annular groove 211 on its inner wall. A gap exists between the bottom of the annular groove 211 and the surface of the feeding push rod 3. The feeding push rod 3 is provided with a positioning member 32 located within the annular groove 211. The positioning member 32 can be integrally connected to the feeding push rod 3 or fixedly connected thereto. The positioning member 32 can be configured as a retaining ring fixedly sleeved on the feeding push rod 3. The elastic return member 31 can be configured as a compression spring, located within the annular groove 211 and sleeved on the feeding push rod 3. Its top and bottom ends are supported by the positioning member 32 and the bottom wall of the annular groove 211, respectively. When the feeding push rod 3 slides downward from the highest position to the lowest position under the driving action of the driver 5151, the elastic reset member 31 is gradually compressed and reaches the maximum compression when the feeding push rod 3 is at the lowest position, that is, the elastic potential energy of the elastic reset member 31 reaches the maximum, and the driver 5151 releases the control, and under the action of the elastic force of the elastic reset member 31, the feeding push rod 3 can be driven to slide upward, and finally slide upward to the original position of the highest position.

[0057] Implementation Case 2:

[0058] A feeding device, referring to Figure 10-11 and combined Figure 1-9 , including a mounting base 8 and a plurality of feeding units d, wherein the feeding units d are as shown in Example 1. The mounting base 8 is arranged on the pot cover 9, and a hollow portion 8a is formed at the bottom thereof. The plurality of feeding units d are arranged on the mounting base 8, and the discharge port 2b at the bottom of the feeding unit d is located within the range of the hollow portion 8a. The mounting base 8 has a positioning structure 81. The positioning structure 81 is positioned on the pot cover 9 so that the mounting base 8 can be positioned on the pot cover 9, thereby connecting the hollow portion 8a and the feeding window 9a on the pot cover 9. The seasonings fed from the feeding unit d through the discharge port 2b can be fed into the pot.

[0059] In this embodiment, multiple feeding units d are uniformly set on the mounting base 8, and the mounting base 8 is positioned on the pot cover 9 through the positioning structure 81, so that multiple feeding units d can be used to add seasonings to the pot. Users can add different seasonings to different feeding units d, and add them according to the different seasonings and amounts required for cooking, making it more convenient for users to use.

[0060] In this embodiment, the pot cover 9 has a sunken platform structure 91 arranged around the edge of the feeding window 9a and recessed inward relative to the top surface of the pot cover 9. The positioning structure 81 is a linearly extending and closed structure, the shape of which matches the feeding window 9a and is formed by the protrusion of the bottom surface of the mounting seat 8. The bottom of the positioning structure 81 is supported on the bottom wall of the sunken platform structure 91, so that the mounting seat 8 and the multiple feeding units d arranged on the mounting seat 8 can be stably positioned on the pot cover 9.

[0061] In this embodiment, more specifically, the bottom surface of the mounting base 8 is supported on the top surface of the pot cover 9, and the positioning structure 81 on the mounting base 8 is supported on the sink structure 91 of the pot cover 9, so that the overall area of ​​the mounting base 8 supported on the pot cover 9 is increased, thereby making the state of the mounting base 8 positioned on the pot cover 9 more stable and reliable.

[0062] In this embodiment, the outer edge of the positioning structure 81 is attached to the side wall of the sink structure 91, so that the mounting seat 8 will not shake when positioned on the pot cover 9, further improving the stability of its position on the pot cover 9.

[0063] In this embodiment, the inner side of the positioning structure 81 defines the edge of the hollow portion 8a, so that the area of ​​the hollow portion 8a is maximized, and the area of ​​the hollow portion 8a is basically equal to the area of ​​the feeding window 9a, which means that more feeding units d can be configured on the mounting seat 8.

[0064] In this embodiment, the feeding units d are arranged on the mounting base 8. The top surface of the positioning base is provided with a receiving groove 82, and a plurality of feeding units d are snap-fitted into the receiving groove 82. The snap-fitting installation of the feeding units d facilitates the user to install the feeding units d on the mounting base 8. The feeding units d are also easy to remove, making it convenient for the user to replace or maintain and clean the feeding units d.

[0065] In this embodiment, more specifically, multiple feeding units d are embedded side by side in the receiving groove 82. The side-by-side arrangement can minimize the area occupied by the feeding units d, thereby maximizing the utilization of the receiving groove 82 and maximizing the number of feeding units d.

[0066] In this embodiment, the bottom of the feeding unit d, i.e., the bottom of the box body 1, has a downwardly protruding discharge spout 12 that extends downwardly through the hollow portion 8a. The discharge port 2b is located on the discharge spout 12. When the mounting base 8 is positioned on the pot lid 9, the discharge port 2b on the discharge spout 12 is lower than the bottom surface of the pot lid 9. This allows the discharge port 2b to be closer to the pot bottom, facilitating the feeding of seasonings. The specific structural shape of the discharge spout 12 can be set to be hemispherical, or it can be set to other shapes such as a cone.

[0067] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
