[0039] The present invention is further described in detail below based on the accompanying drawings and implementation examples.

[0040] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0041] Implementation Case 1:

[0042] A feeding unit, refer to Figure 1-9 as well as Fig.10 , 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 in 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 inlet 2a on the top and a discharge port 2b on the bottom. The top of the box body 1 is provided with a feed inlet 1a at a position corresponding to the feed inlet 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 into the box body 1 through the feed inlet 1a, and the seasoning then enters the cavity of the shell 2 from the feed inlet 2a, and is then put into the pot from the discharge port 2b.

[0043] In this embodiment, the feeding push rod 3 is vertically slidably arranged in the shell 2, and is driven by the driving mechanism, so that the feeding push rod 3 can slide in both directions vertically. A blocking structure 4 is arranged at the bottom end of the feeding push rod 3, and the blocking structure 4 has two states, one state is a first state of blocking the discharge port 2b, 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 of opening the discharge port 2b, 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 make the blocking structure 4 switch 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 seasoning into the pot.

[0044] In this embodiment, by setting two states of the blocking 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; the state of the blocking structure 4 is adjusted by the vertical sliding of the feeding push rod 3 to switch between the first state and the second state, so that the seasoning can be quickly put into the pot to complete the automatic feeding, making it more convenient for users to use.

[0045] In this embodiment, the sealing structure 4 includes a first sealing head 41 and a second sealing head 42 which are 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, the feed port 2a can be sealed, 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.

[0046] In this embodiment, the feeding push rod 3 is limited to a moving stroke, and the moving stroke has a highest position and a lowest position. When the feeding push rod 3 is at the highest position, the first plugging head 41 blocks the discharge port 2b, that is, the plugging structure 4 is in the first state; when the feeding push rod 3 is at the lowest position, the second plugging head 42 blocks the discharge port 2b, that is, the plugging structure 4 is in the first state; when the feeding push rod 3 slides downward from the highest position to the lowest position, the plugging 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. In this process, the seasoning is put into the pot from the discharge port 2b, and the feeding push rod 3 slides upward from the lowest position to the highest position. The plugging structure 4 switches from the first state to the second state and then to the first state. The feeding push rod 3 slides downward from the highest position to the lowest position, and then slides upward to the highest position. This whole process completes a feeding action of the seasoning.

[0047] In this embodiment, the diameter of the feeding push rod 3 is smaller than the diameter of the discharge port 2b, the first plugging head 41 is connected to the bottom end of the feeding push rod 3, and 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, the discharge port 2b and the discharge port 2b form a gap that allows the seasoning to fall, so that the seasoning can be put into the pot.

[0048] 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 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 a very short time, basically no seasoning will fall from the discharge port 2b. Therefore, the amount put in by one seasoning putting action is fixed, so that the precise putting of seasoning can be achieved. The user can perform several putting actions through the driving mechanism according to the required amount of seasoning.

[0049] In this embodiment, the discharge port 2b is defined by the upper hole wall h1 and the lower hole wall h2, and 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 added in each feeding action is quantitative, that is, basically the amount between the first plugging head 41 and the second plugging head 42, and the time when the discharge port 2b is opened in the process of sliding from the highest position to the lowest position is very short, but a very small amount of steam will still enter the shell 2 through the discharge port 2b, which will inevitably cause the seasoning in the shell 2 to become damp after long-term use. Since only a very small amount of steam will enter the shell 2 during each feeding process, it can only affect the seasoning near the discharge port 2b in the shell 2. 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 plugging head 42 and fall out of the discharge port 2b, thereby preventing this part of the seasoning affected by moisture and affecting the dry environment inside the shell 2.

[0050] 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 small amount of damp seasoning can quickly slide down along the upper hole wall h1 and fall out of the discharge port 2b.

[0051] 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.

[0052] In this embodiment, the axis of the feeding push rod 3 corresponds to the center of the discharge port 2b, and the first plugging head 41 and the second plugging head 42 are formed by expanding outward around the feeding push rod 3, and the first plugging head 41 and the second plugging head 42 form a disc-shaped structure. Since the axis of the feeding push rod 3 corresponds to the center of the discharge port 2b, the seasonings put in are evenly distributed in the circumferential direction, so that the seasonings put in the pot are more dispersed and uniform, thereby avoiding the situation that the taste of some parts of the dish is too strong and other parts are too light, which affects the quality of the dish.

[0053] In this embodiment, the bottom surface of the second plugging head 42 is set to a plane, so that during the feeding process, the second plugging head 42 pushes the seasoning downward vertically downward, 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 in the pot. The top surface of the first plugging head 41 is 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 in 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, so that the amount of seasoning fed is more accurate.

[0054] In this embodiment, the driving mechanism is arranged in the box body 1 and is located outside the shell 2. The driving mechanism includes a driver 51, a driving member 52, and a swing rod 53, wherein the driving rod is driven by the driver 51 to slide vertically, the swing rod 53 has a rotation fulcrum so that the swing rod 53 can swing around its rotation fulcrum, and the two ends of the swing rod 53 are respectively movably connected to the feeding push rod 3 and the driving member 52. Therefore, when the driver 51 drives the driving member 52 to slide vertically, the feeding push rod 3 can be driven to slide vertically through the transmission action of the swing rod 53, so that the blocking structure 4 blocks the feed port 2a or opens the discharge port 2b, thereby executing the feeding of the seasoning.

[0055] In this embodiment, since the seasoning put into the pot is basically the seasoning between the first plugging head 41 and the second plugging head 42, that is to say, the feeding amount of the feeding push rod 3 for each reciprocating sliding of the feeding unit in this embodiment is a, and the feeding amount required by the user is b. The feeding number n of the feeding unit is determined according to the required feeding amount b, n=b / a, and the feeding can be completed by controlling the driving mechanism to drive the feeding push rod to slide back and forth n times, thereby achieving the purpose of accurately controlling the feeding amount.

[0056] In this embodiment, the driving mechanism is provided with a rocker arm 53, and the lever principle can be used to easily and efficiently realize the vertical sliding of the feeding push rod 3, so that the seasoning can be accurately added; in addition, it should be noted that since the feeding unit of this embodiment needs to be set on the pot cover 9, the feeding unit should not be set too high, and the vertical space occupied by the driving mechanism is relatively small, so that the height of the feeding unit can be better limited.

[0057] In this embodiment, for the specific driving mode of the driving mechanism for the feeding push rod 3, the driver 51 drives the driving member 52 to move vertically upward, so that the feeding push rod 3 slides vertically downward and moves from the highest position to the lowest position. The feeding push rod 3 is provided with an elastic reset member 31, and the function of the elastic reset member 31 is to drive the feeding push rod 3 to reset, that is, to slide vertically upward from the lowest position to the highest position.

[0058] In this embodiment, based on the fact that the downward stroke of the feeding push rod 3 is controlled by the driving mechanism, and the upward stroke is controlled by the elastic reset member 31, the driver 51 can be specifically set as an electromagnetic device, and correspondingly, the driving member 52 is set as an electromagnetic push rod. The principle of the electromagnetic device and the electromagnetic push rod is to use the electromagnetic principle to perform linear motion, that is, the driver 51 drives the driving member 52 to move vertically upward through electromagnetic action. The configuration of the electromagnetic device and the electromagnetic push rod has a characteristic, that is, the thrust of the electromagnetic push rod is relatively large, corresponding to the vertical upward movement of the driving member 52, which can drive the feeding push rod 3 to slide rapidly from the highest position to the lowest position, while the pulling force of the electromagnetic push rod is relatively small, which is not conducive to the feeding push rod 3 sliding upward from the lowest position to the highest position, and this process is implemented by the elastic reset member 31, thereby avoiding the shortcomings of the electromagnetic push rod. In addition, it can also reduce the consumption of the electromagnetic push rod, avoid the situation where the equipment is fatigued after long-term use and the movement is not accurate, and then affect the driving accuracy.

[0059] In this embodiment, a vertically extending guide sleeve 21 is provided in the housing 2, the guide sleeve 21 is connected to the top of the housing 2, and the guide sleeve 21 is slidably sleeved on the feeding push rod 3. The guide sleeve 21 guides the feeding push rod 3, and can prevent the feeding push rod 3 from radially offsetting or misaligning, thereby ensuring that during its vertical sliding process, the blocking structure 4 can be aligned with the discharge port 2b to block or open the discharge port 2b.

[0060] In this embodiment, the guide sleeve 21 has a concave annular groove 211 on its inner wall, and there is a gap 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 in the annular groove 211, and the positioning member 32 can be integrally connected to the feeding push rod 3, or can be fixedly connected to the feeding push rod 3, and the positioning member 32 can be set as a clamping ring fixedly sleeved on the feeding push rod 3. The elastic reset member 31 can be specifically set as a compression spring, and is located in the annular groove 211 and sleeved on the feeding push rod 3, and its top and bottom ends are supported on 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 51, 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, the driver 51 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.

[0061] In this embodiment, most of the feeding push rod 3 is located in the shell 2, and a part of it passes through the top of the shell 2. The end of the swing rod 53 close to the feeding push rod 3 is movably connected to the top of the feeding push rod 3. This arrangement can prevent the swing rod 53 from contacting the seasoning.

[0062] In this embodiment, for the setting of the rocker arm 53, a connecting seat 11 is provided in the box body 1, and the connecting seat 11 is located outside the shell body 2, and can be connected to the shell body 2 or the box body 1. The connecting seat 11 has two connecting holes, and the rocker arm 53 is respectively provided with rotating shafts 531 on both sides of the middle thereof, and the rotating shaft 531 constitutes the rotation fulcrum of the rocker arm 53. The rotating shaft 531 can be rotatably inserted into the corresponding connecting hole on the connecting seat 11, so that the rocker arm 53 can rotate around the rotating shaft 531, that is, the rotation fulcrum.

[0063] In this embodiment, for the movable connection between the swing rod 53 and the feeding push rod 3, the swing rod 53 has a transmission arm 6 at one end thereof close to the stripping push rod, and the transmission arm 6 extends along the length direction of the swing rod 53, that is, it is equivalent to the extension section of the swing rod 53. The feeding push rod 3 has two limit parts 33 at its top end, and the two limit parts 33 are spaced apart along the axial direction of the feeding push rod 3, and the transmission arm 6 of the swing rod 53 is limited between the two limit parts 33. Under the action of the driver 51, the swing rod 53 rotates around its rotation fulcrum, and the transmission arm 6 of the swing rod 53 pushes the limit part 33 located below downward to drive the feeding push rod 3 to slide downward, or pushes the limit part 33 located above upward to drive the feeding push rod 3 to slide upward.

[0064] In this embodiment, by setting two spaced limit portions 33 on the feeding push rod 3 and then limiting the transmission arm 6 of the rocker arm 53 between the two limit portions 33, the feeding push rod 3 and the rocker arm 53 can be flexibly connected, thereby driving the stripping push rod to slide vertically. This movable connection has a simple structure and is easy to disassemble and maintain.

[0065] In this embodiment, the surface of the feeding push rod 3 has a recessed slot 34 penetrated by the transmission arm 6 , and the slot 34 has two slot walls spaced apart along the axial direction of the feeding push rod 3 , and the two slot walls respectively form two corresponding limit portions 33 .

[0066] In this embodiment, the two side edges of the transmission arm 6 are respectively abutted against the corresponding limit parts 33, so that there will be no looseness between the transmission arm 6 and the stripping push rod, so that the bidirectional sliding of the feeding push rod 3 in the vertical direction remains stable, and it can also ensure that the feeding and sealing structure 4 will not be loose when sealing the discharge port 2b, resulting in gaps and causing seasoning leakage.

[0067] In this embodiment, the width of the transmission arm 6 is smaller than the spacing between the two limit portions 33, and two abutment portions 61 protruding toward the two sides of the transmission arm 6 are formed on both sides of the transmission arm 6, and the two abutment portions 61 abut against the corresponding limit portions 33. The relationship between the width of the transmission arm 6 and the spacing between the two limit portions 33 can ensure that the swing arm 53 and the feeding push rod 3 will not get stuck or even jammed during the relative movement.

[0068] In this embodiment, the abutment portion 61 has an arc-shaped structure, so that when the rocker arm 53 rotates and drives the feeding push rod 3 to slide vertically, the friction resistance generated between the abutment portion 61 and the limiting portion 33 is small, thereby making the feeding push rod 3 slide vertically more smoothly.

[0069] In this embodiment, the end of the swing rod 53 close to the feeding push rod 3 has two transmission arms 6, and the two transmission arms 6 are spaced apart from each other. The surface of the feeding push rod 3 has two oppositely arranged slots 34, and the two transmission arms 6 respectively pass through the corresponding slots 34. By providing two slots 34 and two transmission arms 6 matching therewith, and the symmetrical position relationship, the mutual force between the feeding push rod 3 and the swing rod 53 is more stable and reliable, which is conducive to improving the stability of the vertical sliding of the feeding push rod 3.

[0070] In this embodiment, a blocking structure 7 is provided on the rocker rod 53, which blocks the feeding push rod 3 from sliding upward when the feeding push rod 3 is in the highest position, blocks the feeding push rod 3 from sliding downward when the feeding push rod 3 is in the lowest position, and releases the blocking of the feeding push rod 3 when the feeding push rod 3 transitions between the highest position and the lowest position.

[0071] In this embodiment, the vertical movement stroke of the feeding push rod 3 is limited by the driving mechanism, and the feeding structure is used to block or open the feeding port 2a, so the accuracy of the movement stroke of the feeding push rod 3 directly affects the implementation of feeding and whether the seasoning will leak, and the accuracy of the driving mechanism, especially the maintenance of its accuracy after long-term use, directly determines the accuracy of the movement stroke of the feeding push rod 3. By setting a limit structure, the highest and lowest positions of the feeding push rod 3 can be locked, so that the accuracy of the movement stroke of the feeding push rod 3 can still be guaranteed when the accuracy of the driving mechanism decreases, thereby ensuring the accurate implementation of feeding and avoiding the leakage of seasoning.

[0072] In this embodiment, the blocking structure 7 includes two blocking units 71, which are spaced apart from each other along the axial direction of the swing rod 53 and are arranged on the swing rod 53. When the feeding push rod 3 descends from the highest position to the lowest position, or rises from the lowest position to the highest position, the lateral spacing between the two blocking units 71 gradually increases and then gradually decreases, and when the feeding push rod 3 is at the highest position or the lowest position, the two blocking units 71 clamp the feeding push rod 3.

[0073] In this embodiment, by configuring the blocking structure 7 to be two blocking units 71, the change in the lateral spacing between the two blocking units 71 during the swinging of the rocker arm 53 is utilized. When the feeding push rod 3 is in the highest position or the lowest position, the two blocking units 71 can cleverly clamp the feeding push rod 3, thereby locking the feeding push rod 3 in the highest position and the lowest position, thereby improving the accuracy of the moving stroke of the feeding push rod 3.

[0074] In this embodiment, more specifically, the two blocking units 71 are both located on the transmission arm 6. The blocking unit 71 can be an integral structure with the transmission arm 6, or the blocking unit 71 can be fixedly connected to the transmission arm 6. In addition, the two transmission arms 6 at one end of the swing rod 53 are each provided with two blocking units 71, so that the clamping effect of the two groups of blocking units 71 on the feeding push rod 3 is more secure.

[0075] In this embodiment, the movable connection mode between the driving member 52 and the rocker arm 53, and the movable connection mode between the feeding push rod 3 and the rocker arm 53 are the same, which will not be repeated here.

[0076] Implementation Case 2:

[0077] A feeding device, referring to Figure 10-12 Combined with Figure 1-9 , including a mounting seat 8 and a plurality of feeding units d, wherein the feeding units d are as shown in Example 1. The mounting seat 8 is arranged on the pot cover 9, and a hollow portion 8a is provided at the bottom thereof, and a plurality of feeding units d are arranged on the mounting seat 8, and a discharge port 2b at the bottom of the feeding unit d is located within the range of the hollow portion 8a, and the mounting seat 8 has a positioning structure 81, and the positioning structure 81 is positioned on the pot cover 9, that is, the mounting seat 8 can be positioned on the pot cover 9, so that the hollow portion 8a and the feeding window 9a on the pot cover 9 are connected, and the seasonings fed by the feeding unit d through the discharge port 2b can be fed into the pot.

[0078] In this embodiment, multiple feeding units d are uniformly arranged on the mounting seat 8, and the mounting seat 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 into the pot. Users can add different seasonings to different feeding units d respectively, and add different seasonings and amounts required for cooking, making it more convenient for users to use.

[0079] In this embodiment, the pot cover 9 has a sunken platform structure 91 which is arranged around the edge of the feeding window 9a and is recessed inward relative to the top surface of the pot cover 9. The positioning structure 81 is a linearly extending and closed structure, whose shape 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.

[0080] 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 supporting area of ​​the mounting base 8 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.

[0081] 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.

[0082] 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.

[0083] In this embodiment, for the arrangement of the feeding unit d on the mounting seat 8, the top surface of the positioning seat is provided with a receiving groove 82, and a plurality of feeding units d are embedded in the receiving groove 82. The feeding units d are installed and arranged by the embedding method, which is convenient for the user to install and arrange the feeding units d on the mounting seat 8, and the feeding units d are also easy to disassemble, which is convenient for the user to replace or maintain and clean the feeding units d.

[0084] In this embodiment, more specifically, a plurality of feeding units d are embedded in the receiving groove 82 side by side. 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.

[0085] In this embodiment, the bottom of the feeding unit d, i.e., the bottom of the box body 1, has a discharge nozzle 12 which is convex downward and passes through the hollow portion 8a downward. The discharge port 2b is located on the discharge nozzle 12. When the mounting base 8 is positioned on the pot cover 9, the level of the discharge port 2b on the discharge nozzle 12 is lower than the bottom surface of the pot cover 9, so that the distance between the discharge port 2b and the pot bottom can be closer, which is conducive to the feeding of seasoning. The specific structural shape of the discharge nozzle 12 can be set to be hemispherical, or it can be set to other shapes such as a cone.
