Description

Technical Field

[0001] This utility model relates to a feeding unit and feeding device, belonging to the technical field of kitchen appliances. Background Technology

[0002] Traditional cooking relies on the operator's skill and experience, especially the seasonings, which affect the taste. This is particularly true for Chinese dishes, where many inexperienced cooks struggle to control the amount of seasonings and the precision of adding them, resulting in unsatisfactory food quality. Alternatively, cooks may become flustered and overwhelmed by the need to add multiple different seasonings, further hindering the control of food quality. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a feeding unit and feeding device, which has a simple structural design for transmitting the feeding action, is easy to disassemble and maintain, and the feeding action is smooth and will not jam.

[0004] This utility model is achieved through the following technical solution.

[0005] A feeding unit, comprising:

[0006] The housing has an inlet at the top and an outlet at the bottom, and the cavity inside the housing is used to hold seasonings.

[0007] The feeding push rod is vertically slidably disposed inside the housing, and its bottom end is provided with a sealing structure for sealing or opening the discharge port; the feeding push rod has two limiting parts spaced apart along its axial direction;

[0008] The swing arm has a pivot point and is driven by an external force. One end of the swing arm near the feeding push rod has a transmission arm, which is confined between the two limiting parts.

[0009] As a further improvement of this utility model, the surface of the feeding push rod has a recessed groove that is penetrated by the transmission arm; the groove has two groove wall surfaces spaced apart along the axial direction of the feeding push rod, and the two groove wall surfaces respectively form two corresponding limiting parts.

[0010] As a further improvement of this utility model, the two sides of the transmission arm respectively abut against the corresponding limiting part.

[0011] As a further improvement of this utility model, the width of the transmission arm is less than the distance between the two limiting parts, and two abutting parts protruding towards the two sides of the transmission arm are formed on both sides of the transmission arm, and the two abutting parts abut against the corresponding limiting parts respectively.

[0012] As a further improvement of this utility model, the abutting part has an arc-shaped structure.

[0013] As a further improvement of this utility model, the end of the swing arm near the feeding push rod has two transmission arms, and the two transmission arms are spaced apart from each other; the surface of the feeding push rod has two oppositely arranged slots, and the two transmission arms pass through the corresponding slots respectively.

[0014] As a further improvement of this utility model, a vertically extending guide sleeve is provided inside the housing, and the guide sleeve is slidably sleeved on the feeding push rod.

[0015] As a further improvement of this utility model, it also includes a driver and a driving member that is driven to move vertically by the driver; the driving member has two limiting portions spaced apart along its axial direction, and the swing arm has the transmission arm at one end near the driving member and is limited between the two limiting portions.

[0016] As a further improvement of this utility model, the driver drives the driving member to move vertically upward, so that the feeding push rod moves vertically from the highest position to the lowest position. The feeding push rod is provided with an elastic reset member, which is used to drive the feeding push rod to vertically reset from the lowest position to the highest position.

[0017] A feeding device includes a mounting base with a hollowed-out portion at the bottom and a plurality of feeding units disposed on the mounting base; the discharge port of the feeding unit is located within the range of the hollowed-out portion; the mounting base is disposed on a pot lid, and the hollowed-out portion is connected to the feeding window on the pot lid.

[0018] The beneficial effects of this utility model are:

[0019] By setting two spaced limiting parts on the feeding push rod and then restricting the transmission arm of the swing rod between the two limiting parts, the feeding push rod and the swing rod can be movably connected, thereby driving the unloading push rod to slide vertically. This movable connection structure is simple and easy to disassemble and maintain.

[0020] The relationship between the width of the transmission arm and the distance between the two limiting parts is designed so that the swing arm and the feeding push rod will not get stuck or jammed during relative movement. The frictional resistance between the arc-shaped contact part and the limiting part is small, which makes the feeding push rod slide more smoothly in the vertical direction.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0036] Implementation Case 1:

[0037] A feeding unit, as per regulations Figure 1-9 as well as Figure 10A container is installed on the lid 9 of a pot and is used to add seasonings into the pot. It includes a box body 1, a shell 2, a feeding pusher 3, and a driving mechanism. The box body 1 is hollow and serves as a container. The shell 2 and the driving mechanism are both located inside the box body 1. The shell 2 is also hollow, and its internal cavity is used to hold the seasonings. It has a feeding port 2a at the top and a discharging port 2b at the bottom. The top of the box body 1 has 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 discharging port is formed at the bottom of the box body 1. The user can add seasonings into the box body 1 through the feeding port 1a. The seasonings then enter the cavity of the shell 2 through the feeding port 2a and are then added into the pot through the discharging port 2b.

[0038] In this embodiment, the feeding push rod 3 is vertically slidable within the housing 2 and is driven by a drive mechanism, enabling it to slide vertically in both directions. A sealing structure 4 is located at the bottom of the feeding push rod 3. The sealing structure 4 has two states: a first state where it seals the outlet 2b, confining the seasoning within the cavity of the housing 2; and a second state where it opens the outlet 2b, allowing the seasoning within the housing 2 to be fed into the pot through the outlet 2b. The vertical sliding of the feeding push rod 3 allows the sealing structure 4 to switch between the first and second states, i.e., the drive mechanism drives the feeding push rod 3 vertically, thus enabling the feeding unit to dispense the seasoning into the pot.

[0039] In this embodiment, by setting two states of the sealing structure 4, in the first state, sealing the feed inlet 2a can prevent the seasoning from leaking into the pot and also prevent steam from the pot from entering the shell 2 and causing the seasoning to become damp. In the second state, the seasoning can be added into the pot through the feed inlet 2a. The state of the sealing structure 4 can be switched between the first and second states by sliding the feeding push rod 3 vertically, which can quickly add the seasoning into the pot and complete the automatic feeding, making it more convenient for users.

[0040] In this embodiment, the sealing structure 4 includes a first sealing head 41 and a second sealing head 42 arranged at intervals from bottom to top. When the first sealing head 41 and the second sealing head 42 are located at the feed inlet 2a, the feed inlet 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 outlet 2b and the second sealing head 42 is located above the feed inlet 2a, the discharge outlet 2b is opened, which corresponds to the second state of the sealing structure 4.

[0041] In this embodiment, the feeding pusher 3 has a defined travel distance, which includes a highest position and a lowest position. When the feeding pusher 3 is at its highest position, the first sealing head 41 seals the outlet 2b, i.e., the sealing structure 4 is in the first state. When the feeding pusher 3 is at its lowest position, the second sealing head 42 seals the outlet 2b, i.e., the sealing structure 4 is in the first state. As the feeding pusher 3 slides down from the highest position to the lowest position, the sealing structure 4 gradually switches from the first state to the second state, i.e., the outlet 2b is opened, and then gradually switches back to the first state. During this process, the seasoning is fed into the pot from the outlet 2b. As the feeding pusher 3 slides up from the lowest position to the highest position, the sealing structure 4 switches from the first state to the second state and then back to the first state. This entire process of the feeding pusher 3 sliding down from the highest position to the lowest position and then up to the highest position completes one feeding action of the seasoning.

[0042] In this embodiment, the diameter of the feeding push rod 3 is smaller than the diameter of the outlet 2b. The first sealing head 41 is connected to the bottom end of the feeding push rod 3, or it can be connected to the rod body of the feeding push rod 3, while the second sealing head 42 is connected to the rod body of the feeding push rod 3. When the feeding push rod 3 slides down from its highest position, and the first sealing head 41 is below the inlet 2a and the second sealing head 42 is above the inlet 2a, the feeding push rod 3 is exactly at the inlet 2a. Since the diameter of the feeding push rod 3 is smaller than the outlet 2b, the outlet 2b and the outlet 2b form a gap that allows the seasoning to fall, thus enabling the seasoning to be added into the pot.

[0043] In this embodiment, the first sealing head 41 and the second sealing head 42 can block the discharge port 2b. The diameters of the first sealing head 41 and the second sealing head 42 are larger than the feeding push rod 3. When the feeding push rod 3 slides down from the highest position to the lowest position, the second sealing head 42 pushes the seasoning between the first sealing head 41 and the second sealing head 42 downward, thus pushing the seasoning between the first sealing head 41 and the second sealing head 42 downward out of the discharge port 2b. The seasoning added to the pot is basically the seasoning between the first sealing head 41 and the second sealing head 42, that is, the amount added is fixed. When the feeding push rod 3 slides up from the lowest position to the highest position, since the discharge port 2b is opened for a very short time, there is basically no seasoning falling from the discharge port 2b. Therefore, the amount of seasoning added in one feeding action is fixed, thus achieving precise seasoning addition. The user can perform several feeding actions through the drive mechanism according to the required amount of seasoning.

[0044] 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 sealing head 42, and there is no gap between the lower hole wall h2 and the outer peripheral surface of the second sealing head 42. The amount of seasoning dispensed in each feeding action is fixed, that is, basically the amount between the first sealing head 41 and the second sealing head 42. During the process of sliding from the highest position to the lowest position, the discharge port 2b is opened for a very short time, but a very small amount of steam will still enter the shell 2 through the discharge port 2b. After long-term use, this will inevitably cause the seasoning inside the shell 2 to become damp. Since only a very small amount of steam enters the shell 2 during each feeding process, it can only affect the seasoning inside the shell 2 near the discharge port 2b. As the feeding pusher 3 slides 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 avoiding the influence of moisture and the very small amount of seasoning on the dry environment inside the shell 2.

[0045] In this embodiment, the upper hole wall h1 gradually tapers inward from top to bottom until the bottom edge of the upper hole wall h1, thus forming a sloping structure, which allows a very small amount of damp seasoning to slide down quickly along the upper hole wall h1 and fall out of the discharge port 2b.

[0046] In this embodiment, when the feeding pusher 3 is at its highest position, the top edge of the outer peripheral surface of the second sealing head 42 is higher than the bottom edge of the lower hole wall h2, so that the outer peripheral surface of the second sealing head 42 and the upper hole wall h1 form a collection groove c, and a very small amount of damp seasoning can be temporarily collected in the collection groove c. When the feeding pusher 3 slides upward from the lowest position, the very small amount of damp seasoning collected in the collection groove c can be quickly dropped.

[0047] In this embodiment, the axis of the feeding push rod 3 corresponds to the center of the discharge port 2b. The first sealing head 41 and the second sealing head 42 both 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 added seasonings are evenly distributed in the circumferential direction, ensuring that the seasonings added to the pot are relatively dispersed and uniform. This avoids situations where some parts of the dish are too strong in flavor while others are too bland, thus affecting the quality of the dish.

[0048] In this embodiment, the bottom surface of the second sealing head 42 is set as a plane, so that during the feeding process, the downward pushing direction of the second sealing head 42 on the seasoning is vertically downward, allowing the seasoning between the first sealing head 41 and the second sealing head 42 to be quickly pushed out of the discharge port 2b, which is beneficial for the addition of seasoning to the pot. The top surface of the first sealing head 41 is inclined downward from the connection point to the feeding push rod 3 to its outer periphery, so that the top surface of the first sealing head 41 presents a sloping structure. During the feeding process, the seasoning can quickly spread outward along the top surface of the first sealing 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 sealing head 41, making the amount of seasoning added more accurate.

[0049] In this embodiment, the drive mechanism is located inside the housing 1 and on the outside of the shell 2. The drive mechanism includes a driver 51, a drive member 52, and a swing rod 53. The drive rod is driven by the driver 51 and can slide vertically. The swing rod 53 has a pivot point, allowing it to swing around this pivot point. The two ends of the swing rod 53 are movably connected to the feeding push rod 3 and the drive member 52, respectively. Therefore, when the driver 51 drives the drive member 52 to slide vertically, the swing rod 53, through its transmission action, can drive the feeding push rod 3 to slide vertically, causing the sealing structure 4 to block the inlet 2a or open the outlet 2b, thereby dispensing the seasoning.

[0050] In this embodiment, since the seasonings added to the pot are primarily those between the first sealing head 41 and the second sealing head 42, the amount of seasoning added by the feeding unit's feeding push rod 3 with each reciprocating slide is a fixed value. The amount of seasoning added by the feeding unit each time is 'a', and the amount of seasoning required by the user is 'b'. Based on the required amount of seasoning 'b', the number of feeding cycles 'n' is determined, where 'n' = 'b / a'. By controlling the drive mechanism to drive the feeding push rod to reciprocate 'n' times, the feeding is completed, achieving precise control of the amount of seasoning added.

[0051] In this embodiment, the drive mechanism is equipped with a swing arm 53, which can easily and efficiently realize the vertical sliding of the feeding push rod 3 by using the lever principle, thereby accurately feeding the seasonings. In addition, it should be noted that since the feeding unit in this embodiment needs to be set on the pot lid 9, the feeding unit should not be set too high. The vertical space occupied by the drive mechanism is small, so the height of the feeding unit can be well limited.

[0052] In this embodiment, regarding the specific driving method of the drive mechanism for the feeding push rod 3, the driver 51 drives the drive component 52 to move vertically upward, 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 reset component 31, the function of which is to drive the feeding push rod 3 to reset, that is, to slide vertically upward from the lowest position to the highest position.

[0053] In this embodiment, the downward stroke of the feeding push rod 3 is controlled by the drive mechanism, while the upward stroke is controlled by the elastic reset member 31. The driver 51 can be specifically configured as an electromagnet, and correspondingly, the drive member 52 is configured as an electromagnetic push rod. The principle of the electromagnet and the electromagnetic push rod is to use electromagnetic principles to achieve linear motion; that is, the driver 51 drives the drive member 52 to move vertically upward through electromagnetic action. A characteristic of the configuration of the electromagnet and the electromagnetic push rod is that the electromagnetic push rod has a relatively large thrust, corresponding to the vertical upward movement of the drive member 52, enabling the feeding push rod 3 to quickly slide from the highest position to the lowest position. The electromagnetic push rod, on the other hand, has a smaller pulling force, which is less conducive to the feeding push rod 3 sliding from the lowest position to the highest position. This process is implemented by the elastic reset member 31, thus avoiding the disadvantages of the electromagnetic push rod. Furthermore, it can reduce the wear and tear on the electromagnetic push rod, preventing fatigue after long-term use that could lead to inaccurate movements and affect the accuracy of the drive.

[0054] In this embodiment, a vertically extending guide sleeve 21 is provided inside 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 radial offset or misalignment, thereby ensuring that the sealing structure 4 can be aligned with the discharge port 2b during its vertical sliding process, so as to block or open the discharge port 2b.

[0055] In this embodiment, the guide sleeve 21 has an inwardly recessed annular groove 211 on its inner wall, with gaps between the bottom of the groove 211 and the surface of the feeding push rod 3. The feeding push rod 3 is provided with a positioning element 32 located within the annular groove 211. The positioning element 32 can be integrally connected to the feeding push rod 3 or fixedly connected to the feeding push rod 3. The positioning element 32 can be configured as a retaining ring fixedly sleeved on the feeding push rod 3. The elastic reset element 31 can be specifically configured as a compression spring, located within the annular groove 211 and sleeved on the feeding push rod 3, with its top and bottom ends supported on the positioning element 32 and the bottom wall of the annular groove 211, respectively. When the feeding push rod 3 slides down 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 in 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 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.

[0056] In this embodiment, the feeding push rod 3 is mostly located inside the housing 2, with a portion extending out of the top of the housing 2. The end of the swing rod 53 near 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 coming into contact with the seasoning.

[0057] In this embodiment, for the setting of the swing arm 53, a connecting seat 11 is provided inside the housing 1. The connecting seat 11 is located outside the housing 2 and can be connected to the housing 2 or the housing 1. The connecting seat 11 has two connecting holes. The swing arm 53 has a rotating shaft 531 on both sides of its middle part. The rotating shaft 531 constitutes the rotation fulcrum of the swing arm 53. The rotating shaft 531 can be rotatably inserted into the corresponding connecting hole on the connecting seat 11, so that the swing arm 53 can rotate around the rotating shaft 531, i.e., the rotation fulcrum.

[0058] In this embodiment, regarding the movable connection between the swing arm 53 and the feeding push rod 3, the swing arm 53 has a transmission arm 6 at its end near the unloading push rod. The transmission arm 6 extends along the length of the swing arm 53, essentially acting as an extension of the swing arm 53. The feeding push rod 3 has two limiting portions 33 at its top, spaced apart axially along the feeding push rod 3. The transmission arm 6 of the swing arm 53 is confined between the two limiting portions 33. Under the action of the driver 51, the swing arm 53 rotates around its pivot point. The transmission arm 6 of the swing arm 53 then pushes downwards towards the lower limiting portion 33, thereby causing the feeding push rod 3 to slide downwards, or pushes upwards towards the upper limiting portion 33, thereby causing the feeding push rod 3 to slide upwards.

[0059] In this embodiment, by setting two spaced limiting parts 33 on the feeding push rod 3 and then restricting the transmission arm 6 of the swing rod 53 between the two limiting parts 33, the feeding push rod 3 and the swing rod 53 can be movably connected, thereby driving the unloading push rod to slide vertically. This movable connection structure is simple and easy to disassemble and maintain.

[0060] In this embodiment, the surface of the feeding push rod 3 has a recessed groove 34 that is penetrated by the transmission arm 6. The groove 34 has two groove walls spaced apart along the axial direction of the feeding push rod 3, and the two groove walls respectively form two corresponding limiting parts 33.

[0061] In this embodiment, the two sides of the transmission arm 6 abut against the corresponding limiting part 33, so that there will be no loosening between the transmission arm 6 and the unloading push rod, so that the feeding push rod 3 can slide smoothly in both directions in the vertical direction. It can also ensure that the sealing structure 4 will not loosen when sealing the discharge port 2b, so as not to cause gaps and leakage of seasoning.

[0062] In this embodiment, the width of the transmission arm 6 is less than the distance between the two limiting parts 33. Two abutment parts 61 protrude from both sides of the transmission arm 6, and each abuts against the corresponding limiting part 33. This relationship between the width of the transmission arm 6 and the distance between the two limiting parts 33 ensures that the swing arm 53 and the feeding push rod 3 will not jam or become stuck during their relative movement.

[0063] In this embodiment, the abutment part 61 has an arc-shaped structure, which makes the frictional resistance between the abutment part 61 and the limiting part 33 smaller during the process of the swing rod 53 rotating and driving the feeding push rod 3 to slide vertically, thus making the feeding push rod 3 slide more smoothly along the vertical direction.

[0064] In this embodiment, the end of the swing arm 53 near the feeding push rod 3 has two transmission arms 6, which are spaced apart from each other. The surface of the feeding push rod 3 has two oppositely arranged slots 34, through which the two transmission arms 6 pass respectively. By setting two slots 34 and matching them with two transmission arms 6, and by maintaining a symmetrical position, the interaction force between the feeding push rod 3 and the swing arm 53 is made more stable and reliable, which helps to improve the stability of the vertical sliding of the feeding push rod 3.

[0065] In this embodiment, the swing arm 53 is provided with a blocking structure 7. The blocking structure 7 blocks the feeding push rod 3 from sliding upward when it is at the highest position, blocks the feeding push rod 3 from sliding downward when it is at the lowest position, and releases the blocking of the feeding push rod 3 when it transitions between the highest and lowest positions.

[0066] In this embodiment, the vertical travel of the feeding pusher 3 is limited by the drive mechanism. The feeding structure is used to block or open the feed inlet 2a. Therefore, the accuracy of the feeding pusher 3's travel directly affects the feeding process and whether the seasoning will leak. The accuracy of the drive mechanism, especially its ability to maintain accuracy after long-term use, directly determines the accuracy of the feeding pusher 3's travel. By setting a limit structure, the highest and lowest positions of the feeding pusher 3 can be locked, ensuring the accuracy of the feeding pusher 3's travel even when the accuracy of the drive mechanism decreases. This guarantees accurate feeding and prevents seasoning leakage.

[0067] 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 disposed on the swing rod 53. During the process of the feeding push rod 3 descending from its highest position to its lowest position, or rising from its lowest position to its highest position, the lateral distance between the two blocking units 71 gradually increases and then gradually decreases. Furthermore, when the feeding push rod 3 is in its highest or lowest position, the two blocking units 71 clamp the feeding push rod 3.

[0068] In this embodiment, by setting the blocking structure 7 into two blocking units 71, the change in the lateral distance between the two blocking units 71 during the swing of the swing rod 53 is utilized. When the feeding push rod 3 is in the highest or lowest position, the two blocking units 71 can clamp the feeding push rod 3, thereby locking the highest and lowest positions of the feeding push rod 3 and improving the accuracy of the movement stroke of the feeding push rod 3.

[0069] In this embodiment, more specifically, both blocking units 71 are located on the transmission arm 6. The blocking unit 71 can be an integral structure with the transmission arm 6, or it can be fixedly connected to the transmission arm 6. In addition, each of the two transmission arms 6 at one end of the swing rod 53 is provided with two blocking units 71, thereby making the clamping effect of the two sets of blocking units 71 on the feeding push rod 3 more secure.

[0070] In this embodiment, the movable connection method between the drive component 52 and the swing arm 53, and the movable connection method between the feeding push rod 3 and the swing arm 53 are the same, and will not be described again here.

[0071] Implementation Case 2:

[0072] A feeding device, as described above Figure 10-12 and combined Figure 1-9The system includes a mounting base 8 and multiple feeding units d, as shown in Embodiment 1. The mounting base 8 is mounted on the pot lid 9, and has a hollowed-out portion 8a at its bottom. Multiple feeding units d are mounted on the mounting base 8, and the discharge port 2b at the bottom of the feeding unit d is located within the hollowed-out portion 8a. The mounting base 8 has a positioning structure 81, which is positioned on the pot lid 9, so that the mounting base 8 can be positioned on the pot lid 9, thereby connecting the hollowed-out portion 8a and the feeding window 9a on the pot lid 9. The seasonings fed by the feeding unit d through the discharge port 2b can be fed into the pot.

[0073] In this implementation case, multiple feeding units d are uniformly set on the mounting base 8. The mounting base 8 is positioned on the pot lid 9 through the positioning structure 81, which enables multiple feeding units d to feed seasonings into the pot. Users can add different seasonings to different feeding units d respectively, according to the different seasonings and quantities required for cooking, making it more convenient for users.

[0074] In this embodiment, the pot lid 9 has a recessed platform structure 91 that is set around the edge of the feeding window 9a and recessed inward relative to the top surface of the pot lid 9. The positioning structure 81 is a linearly extended and closed structure whose shape matches the feeding window 9a and is formed by the bottom surface of the mounting base 8. The bottom of the positioning structure 81 is supported on the bottom wall of the recessed platform structure 91, so that the mounting base 8 and the multiple feeding units d set on the mounting base 8 can be stably positioned on the pot lid 9.

[0075] In this embodiment, more specifically, the bottom surface of the mounting base 8 is supported on the top surface of the pot lid 9, and the positioning structure 81 on the mounting base 8 is supported on the sinking structure 91 of the pot lid 9, which increases the overall area of ​​the mounting base 8 supported on the pot lid 9, thereby making the positioning of the mounting base 8 on the pot lid 9 more stable and reliable.

[0076] In this embodiment, the outer edge of the positioning structure 81 is attached to the side wall of the recessed platform structure 91, so that the mounting seat 8 will not wobble when it is positioned on the pot lid 9, further improving the stability of its position on the pot lid 9.

[0077] In this embodiment, the inner side of the positioning structure 81 defines the edge of the hollow part 8a, thereby maximizing the area of ​​the hollow part 8a. Furthermore, the area of ​​the hollow part 8a is approximately equal to the area of ​​the feeding window 9a, which allows for the configuration of more feeding units d on the mounting base 8.

[0078] In this embodiment, regarding the installation method of the feeding unit d on the mounting base 8, the top surface of the positioning base is provided with a receiving groove 82, and multiple feeding units d are snapped into the receiving groove 82. Installing the feeding unit d by snapping it in place makes it convenient for the user to install the feeding unit d on the mounting base 8, and the feeding unit d is also easy to disassemble, facilitating replacement or maintenance and cleaning by the user.

[0079] In this embodiment, more specifically, multiple feeding units d are embedded side by side in the receiving slot 82. The side-by-side arrangement minimizes the area occupied by the feeding units d, thereby maximizing the utilization of the receiving slot 82 and maximizing the number of feeding units d.

[0080] In this embodiment, the bottom of the feeding unit d, i.e., the bottom of the box 1, has a downwardly protruding spout 12 that extends through a hollow section 8a. The outlet 2b is located on the spout 12. When the mounting base 8 is positioned on the pot lid 9, the horizontal height of the outlet 2b on the spout 12 is lower than the bottom surface of the pot lid 9. This allows the outlet 2b to be closer to the bottom of the pot, facilitating the dispensing of seasonings. The specific structural shape of the spout 12 can be hemispherical or, for example, conical or other shapes.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
