Description

Technical Field

[0001] This application relates to the technical field of automatic batching of multi-component raw materials, and particularly to a feeding device. Background Technology

[0002] In the hair dyeing process, various dyes are typically mixed manually in specific proportions to obtain a dyeing composition, which is then applied to the hair to achieve the desired color. This process relies heavily on the hairstylist's experience, resulting in inconsistent color matching. Existing technologies include dye mixing devices that can automatically dispense dye according to the target color, thereby improving color matching accuracy and efficiency.

[0003] However, due to the viscosity of dyes, residual dye remains in the conveying pipeline after the dye mixing device in the existing technology has finished discharging. This residual dye will oxidize and deteriorate upon contact with air, resulting in problems such as color shift and changes in viscosity. During the next batching process, the residual dye will be expelled and mixed into the new dyeing composition. The color, viscosity, and volume of the residual dye are difficult to predict, inevitably causing color deviations in the dyeing composition. This is a technical bottleneck that dye mixing devices cannot avoid. Summary of the Invention

[0004] This application provides a feeding device designed to solve the problem of color deviation that easily occurs in existing dye mixing devices.

[0005] This application provides a feeding device for dispensing a specified amount of raw materials according to a formula, including a shell, a lifting device, one or more first storage units, and a first discharging device; wherein, the lifting device is movably mounted on the shell and can move between a first position and a second position, wherein the height of the second position is higher than the first position, and when the lifting device is in the second position, a discharging area is formed below it for a container to be placed; each first storage unit has a first discharge port, and one or more first storage units are mounted on the lifting device, and when the lifting device is in the second position, each first discharge port can dispense the raw materials into the discharging area; the first discharging device is used to control the discharging and stopping of each first storage unit.

[0006] In the feeding device provided in this application, when the lifting device is raised to the second position, a discharge area is formed below the lifting device for containers to be placed in. One or more first storage units installed on the lifting device directly feed raw materials into the containers in the discharge area through their respective first discharge ports. The material conveying path is short, and it is not easy for raw material residue to appear after discharge, thereby avoiding color deviation problems caused by residual material mixing into the dyeing composition. When the lifting device is lowered to the first position, the feeding device as a whole presents a more compact size and a lower center of gravity, which facilitates storage and transportation.

To simplify the disclosure, specific examples of components and arrangements are described herein. Of course, these are merely examples and are not intended to limit the scope of this application.

[0014] like Figure 1a and Figure 2a As shown, various embodiments of this application provide a feeding device 10 for dispensing a specified amount of raw materials according to a formula. The formula in this application can be understood as a raw material combination scheme designed for a specific purpose, including not only the types of required raw materials but also the dosage of each raw material. The formula can be obtained in various ways; for example, a user can directly input the required types of raw materials and their corresponding dosages through an input interface; the feeding device 10 can download a pre-established or customized formula from a remote server via network communication; the feeding device 10 can also pre-store several standard formulas for direct use by the user as needed.

[0015] Formulas can be quantitative or proportional. Quantitative formulas directly specify the exact amount of each ingredient to be added, for example, specifying ingredient A as 1g, ingredient B as 5g, and ingredient C as 2g. Proportional formulas express the relative proportions of each ingredient as a percentage or ratio, for example, ingredient A as 30%, ingredient B as 50%, and ingredient C as 20%. When the user sets the total weight of the feed (e.g., 100g), the corresponding actual amounts (e.g., 30g, 50g, and 20g) are automatically calculated based on the proportions of each ingredient in the proportional formula. Regardless of whether a quantitative or proportional formula is used, the feeding device 10 converts each ingredient into a defined amount during execution; that is, each ingredient corresponds to a specific target amount. The feeding accuracy of the feeding device 10 is evaluated based on the difference between the actual amount and the target amount. The smaller the difference, the higher the feeding accuracy.

[0016] The following embodiments of this application use the preparation of hair dye as an example to illustrate the specific application process of the feeding device 10. A typical preparation process for hair dye involves adding multiple color dyes into a container as needed, then adding relevant auxiliary materials and mixing thoroughly to obtain a dyeing composition. The color of the dyeing composition is determined by the type and amount of color dye added. The auxiliary materials mainly play a supporting role in adjusting viscosity, hair care, and oxidation color development. The feeding device 10 can also be applied to various scenarios such as skincare products, beverages, inks, and coatings where different raw materials need to be mixed in a set ratio. Raw materials are not limited to liquids or pastes; they can also include other materials with a certain degree of fluidity that can be quantitatively fed through pumping, extrusion, or gravity flow, such as fine particulate suspensions, fluid powders, or gels. The technical solution of this application focuses on controlling the amount of multiple raw materials added according to the formula to achieve automatic and accurate raw material combination. The physical state, specific type, and application of the raw materials do not constitute the technical features of this application, nor should they be used as a basis for limiting the scope of protection.

[0017] like Figure 1a , Figure 2a , Figure 3 , Figure 4 In the embodiment shown, the feeding device 10 specifically includes a housing 11, a lifting device 12, one or more first storage units 121 and a first discharge device 123.

[0018] The lifting device 12 is movably mounted on the housing 11 and can move between a first position and a second position.

[0019] The first storage unit 121 is used to store raw materials of a corresponding type, and its quantity is related to the type of raw material. Each first storage unit 121 has a first discharge port 1211, and the first discharge device 123 can control the discharge and stop of each first discharge port 1211. Each first storage unit 121 is installed on the lifting device 12 and can move together with the lifting device 12.

[0020] In some specific embodiments, the first storage unit 121 is fixedly installed on the lifting device 12, and it can be made easy for the user to introduce raw materials into its interior through reserved holes, openings and other structures.

[0021] exist Figure 6 In some specific embodiments shown, the first storage unit 121 is designed as a detachable structure for easy replacement during use. When the raw materials in the first storage unit 121 are depleted, the user can disassemble the entire first storage unit 121 and replace it with a new first storage unit 121 of the same type, achieving quick plug-and-play functionality. Furthermore, the detachable structure also allows for flexible replacement of raw material types. The user can disassemble the current first storage unit 121 and replace it with a first storage unit 121 containing new types of raw materials, according to the formula requirements of the current task, to support the switching of raw material types between different formulas. The detachable first storage unit 121 may also have pre-drilled holes, openings, or other structures to allow the user to manually introduce raw materials into it. Unless otherwise specified in the following description, the first storage unit 121 is always shown in its installed state.

[0022] The second position of the lifting device 12 during its travel is higher than the first position. The process of the lifting device 12 moving from the first position to the second position can be called rising, and the process of moving from the second position to the first position can be called falling. In this application, "up" and "down" should be understood as relative directions with reference to the direction of gravity when the feeding device 10 is in normal installation and use, used to describe the vertical arrangement of related structures or movement along that direction, rather than the absolute direction of gravity. It should be noted that the rising and falling described in this application for the lifting device 12 are not applicable to abnormal working conditions such as when the feeding device 10 is in a transport state, tilted state, side-mounted state, or even when it is upside down during handling.

[0023] like Figure 1a and Figure 1bAs shown, when the lifting device 12 rises to the second position, a discharge area A is formed below it, allowing the container 20 to be placed inside. Each first discharge port 1211 can feed raw materials into the discharge area A. After the container 20 is placed into the discharge area A, the first discharge device 123 controls each first discharge port 1211 to discharge material. After leaving the first discharge port 1211, the raw material enters the container 20 under the influence of gravity. The state where the lifting device 12 is in the second position will be referred to as the working state of the feeding equipment.

[0024] like Figure 2a and Figure 2b As shown, when the lifting device 12 descends to the first position, its main body or part of its main body occupies the discharge area A, so that the discharge area A no longer has the function of allowing the container 20 to be placed in. This state will be referred to as the non-working state of the feeding device below.

[0025] A specific working process of the aforementioned feeding equipment 10 may include the following steps: a. The feeding equipment 10 obtains the formula and determines the types of raw materials required and the target amount of each raw material.

[0026] b. The lifting device 12 rises to the second position, forming a discharge area A below it that can accommodate the container 20.

[0027] c. Place container 20 into discharge area A.

[0028] d. The first discharge device 123 controls each first discharge port 1211 to discharge materials into the container 20.

[0029] e. After the target amount is completed, the first discharge device 123 controls each first discharge port 1211 to stop discharging.

[0030] f. Remove container 20 from discharge area A.

[0031] e. The lifting device 12 descends to the first position.

[0032] The above-described working process is only one specific implementation method and does not limit the specific working steps of the feeding device. In other implementation methods, the order of steps b and a can be interchanged or performed simultaneously; after removing container 20 in step f, a new container 20 can be directly placed in to start the next round of material discharge process of the feeding device 10.

[0033] As can be seen from the above working process, when the lifting device 12 is in the second position, the first storage unit 121 can directly feed raw materials into the container 20 below through its first discharge port 1211 without needing to go through additional conveying pipelines. This design minimizes the conveying path of raw materials, significantly reduces the residue of raw materials during the conveying process, reduces the risk of pollution and waste caused by raw material residue, and effectively improves the accuracy and consistency of raw material feeding.

[0034] In addition, when the feeding device 10 is not in operation, the lifting device 12 is in the first position, and its structure occupies at least part of the discharge area A, making the feeding device 10 more compact and with a lower center of gravity, which is convenient for storage and transportation.

[0035] In summary, the feeding device 10 in this application eliminates the need for traditional conveying pipelines by setting up a lifting device 12 that can move up and down, thereby improving the discharge accuracy. In addition, it has the characteristics of simple and compact structure and easy storage when not in operation.

[0036] like Figure 1a , Figure 1b , Figure 2a , Figure 2b As shown, in some embodiments, the feeding device 10 further includes a metering device 13 for detecting the container 20 located in the discharge area A to obtain the actual amount of raw material fed into the container 20, thereby establishing closed-loop control. During any of the aforementioned raw material discharge processes, the first discharge device 123 can adjust the discharge status according to the actual amount of raw material fed into the container 20 fed back by the metering device 13, and immediately stop discharging when the actual amount fed into the container reaches or is about to reach the target amount set in the formula, thereby ensuring the feeding accuracy requirements.

[0037] In some embodiments, the feeding device 10 further includes a limiting component (not shown) for locking the position of the lifting device 12. The limiting state of the limiting component includes locking and unlocking. When it is locked, the lifting device 12 cannot move relative to the housing 11. When it is unlocked, the lifting device 12 can move relative to the housing 11. The limiting component can lock the lifting device 12 at least in a first position and a second position.

[0038] The specific implementation of the limiting component is not the focus of this application. It can be implemented by various structures such as elastic buckles, sliding pins, spring locks, ball bearing limiting mechanisms, actuating structures, and magnetic adsorption. Its core principle is that when the lifting device 12 moves to a specific position (such as the aforementioned first position and second position), a mechanical interference or position-holding relationship is established between the lifting device 12 and the side wall of the housing 11, thereby preventing it from moving further. The limiting component can also be released under the action of external force, allowing the lifting device 12 to continue moving.

[0039] The limiting component enables the lifting device 12 to have positioning capabilities during movement. On the one hand, when the feeding device 10 is in working condition, the limiting component can prevent the lifting device 12 from accidentally falling from the second position; when transporting or moving the feeding device 10 in a non-working state, the limiting component can prevent the lifting device 12 from sliding out of the first position and colliding with the outside, thereby ensuring the stability of the feeding device 10. On the other hand, the limiting component can provide position feedback to the user, allowing the user to confirm whether the lifting device 12 has reached either the first or second position during the movement process.

[0040] like Figures 3 to 5 As shown, in some specific embodiments, the housing 11 of the feeding device 10 has a first mounting cavity 111, and the lifting device 12 is slidably mounted in the first mounting cavity 111. A limiting component is disposed between the side wall of the first mounting cavity 111 and the lifting device 12.

[0041] In some embodiments, the limiting component can at least lock the sidewall of the first mounting cavity 111 to the lifting device 12 in a third position, the height of which is between the first position and the second position.

[0042] When the lifting device 12 is in the second position and the limit is released, it will move downward under the action of gravity. If left uncontrolled, it may fall freely to the first position. In some cases, such as when the lifting device 12 itself is heavy (e.g., multiple first storage units 121 are installed, or the total weight of the raw materials it contains is large), or when the distance between the second and first positions is long (resulting in a longer free fall time), the lifting device 12 may experience a large impact when falling to the first position, thereby affecting the structural strength and component life of the feeding equipment 10.

[0043] To alleviate the aforementioned problems, in the embodiments described above, a lockable third position is added between the first and second positions, allowing the lifting device 12 to be temporarily stopped at the third position during descent, thus achieving segmented descent. This effectively reduces the speed of the lifting device 12 when it reaches the first position, minimizing the risk of impact. Simultaneously, this third position also facilitates user operations such as adjustment, observation, and insertion / replacement of the first storage unit 121 when the lifting device 12 is at an intermediate height, improving the practicality and human-machine interface of the feeding equipment 10.

[0044] In other specific embodiments, more limiting positions can be set between the first position and the second position, such as the fourth position, the fifth position, the sixth position, etc., so that the lifting device 12 has a more flexible multi-segment positioning capability to meet the differentiated needs under different operating scenarios or structural dimensions.

[0045] like Figure 1aAs shown, in some specific embodiments, the lifting device 12 is provided with a handle 125, which the user can grasp to apply force to the lifting device 12, and manually pull it from the first position to the second position, or make it return from the second position to the first position.

[0046] In conjunction with the aforementioned embodiments, the handle 125 is also provided with a button 1251, which is coupled to the aforementioned limiting component. The button 1251 responds to the pressing operation to change the limiting state of the limiting component.

[0047] When a user grips the handle 125 to raise or lower the lifting device 12, the user can simultaneously perform limit or release operations via the button 1251 on the handle 125. This combines the lifting operation with the limit control in the same action, allowing the user to complete the entire process with just one hand, thus achieving a better human-computer interaction experience.

[0048] In some specific embodiments, button 1251 can be an electrically controlled structure, generating an electrical signal when the user presses button 1251 and sending it to the limit component. Correspondingly, the limit component can be constructed using an electrically driven method, for example, by incorporating components such as electromagnets, electric push rods, or micro motors. Upon receiving the electrical signal, it drives the corresponding mechanism to unlock, thereby allowing the lifting device 12 to move. If no unlock signal is received, the limit component maintains its original locked state.

[0049] In some specific implementations, button 1251 can adopt a mechanical structure and cooperate with elastic elements such as springs to realize its pressing and rebound functions. Button 1251 is coupled to the limiting component through a mechanical linkage structure, which can specifically adopt a connecting hook, lever, cable, etc. When the user presses button 1251, the pressing force acts on the limiting component through the linkage structure, thereby releasing the lock and allowing the lifting device 12 to move smoothly. When the user releases the button, button 1251 automatically resets, and the limiting component returns to the locked state.

[0050] In other embodiments not shown, the lifting device 12 can also be automatically raised and lowered by a motor drive, eliminating the need for manual lifting or lowering by the user. In this case, the handle 125 is no longer needed; the user simply triggers a control command via a button or touch panel on the housing 11 to control the motor to drive the lifting device 12 from the first position to the second position, or vice versa. Correspondingly, the function of the limit component can be implemented by the motor and its associated control system, using program control to determine and stop the lifting position, thus replacing the mechanical limit component. More specifically, the motor can be a stepper motor, a servo motor, or a DC motor equipped with an encoder, working with the control circuit to detect the current position in real time. When the lifting device 12 reaches the set first or second position, a signal is obtained through a position sensor (such as a photoelectric switch, Hall element, magnetic induction switch, encoder counting, etc.), and the motor action is stopped in time, allowing the lifting device 12 to stably remain at the target position.

[0051] like Figure 1a , Figure 2a , Figure 3 As shown, in some embodiments, the housing 11 of the feeding device 10 has a front face facing the user, and the front face is provided with a cutout portion 114. The front face refers to the face facing the user when the feeding device 10 is placed in a preset normal use state. The cutout portion 114 can perform at least one of the following functions: like Figure 2a As shown, when the lifting device 12 is in the first position, at least part of it is exposed through the cutout 114, allowing the user to directly observe the lifting device 12 through the cutout 114, or further observe the multiple first storage units 121. In this way, the position of the lifting device 12 can be confirmed, and the remaining material status of the first storage units 121 can be observed or it can be determined whether replacement is needed.

[0052] like Figure 1a , Figure 1b As shown, when the lifting device 12 is in the second position, the perforated portion 114 connects to the discharge area A and forms a channel through which the container 20 can pass. The user can insert the container 20 into the discharge area A through the perforated portion 114, or remove the container 20 from the discharge area A through the perforated portion 114.

[0053] When the lifting device 12 moves between the first position and the second position, the user can observe the displacement of the lifting device 12 through the hollow part 114, thereby obtaining clear visual feedback on its position.

[0054] Combination Figure 3 As shown, in some more specific embodiments, the cutout portion 114 extends through the aforementioned first mounting cavity 111.

[0055] like Figure 1a, Figure 2a , Figure 3 In some embodiments shown, the housing 11 is provided with an operation panel 112. When the lifting device 12 is in the second position, the operation panel 112 is responsive to operation. When the lifting device 12 is not in the second position, the operation panel 112 is not responsive to operation.

[0056] The operation panel 112 can be a physical button structure, such as consisting of mechanical buttons, capacitive buttons, or tactile switches; the operation panel 112 can also be a touch structure, such as a capacitive touch panel, a resistive touch screen, or a touch interface integrated with a display screen. When the operation panel 112 is in an responsive state, the user can use the operation panel 112 to perform conventional functions such as power on / off, material discharge control, recipe input, and wireless connection. When the operation panel 112 is in an unresponsive state, any input operation to the operation panel 112 is invalid.

[0057] The control panel 112 is designed to be operable when the lifting device 12 is in the second position and to be in a non-responsive state when the lifting device 12 is not in the second position, thereby effectively preventing users from accidentally operating the feeding device 10 to discharge material when the lifting device 12 has not fully reached the second position or when the lifting device 12 is in the first position or other unsuitable conditions for discharging material.

[0058] The position detection of the lifting device 12 can be achieved in various ways. For example, a Hall sensor can be set at a second position, sending an on-position signal only when the lifting device 12 is detected to be in that second position; the actual position of the lifting device 12 can also be determined by visual recognition, multi-point laser detection, etc. Figure 1a , Figure 2a and Figure 4 In some embodiments shown, the lifting device 12 includes a base 122 and a first cover 126. The base 122 is movably mounted to the housing 11 and has one or more mounting positions for vertically mounting the first storage unit 121. The first cover 126 is movably mounted to the base 122 and is configured to change position in response to user operation, either obscuring or exposing the mounting positions for replacement of the first storage unit 121. Figure 1a , Figure 2a As shown, when the first cover 126 is closed, it covers the first storage unit 121, thereby preventing foreign objects from entering, protecting and restricting the longitudinal position of the first storage unit 121, and enhancing the appearance integrity of the feeding device 10; Figure 4 As shown, when the first cover 126 is opened, the user can easily disassemble, replace or reinstall the first storage unit 121.

[0059] The first storage unit 121 is installed vertically in the mounting position of the base 122, which can assist the discharge process with gravity and reduce the problem of raw material residue. In addition, the vertical installation is also conducive to the side-by-side arrangement of multiple sets of first storage units 121, and at the same time, it can be replaced or maintained without the need for complete disassembly, thus improving maintainability.

[0060] Figure 6 Figure 7 In such Figure 5 , Figure 6 In some embodiments shown, the first storage unit 121 includes a first tank 1212 and a rotating member 1214. The first tank 1212 has an internal cavity for storing raw materials. The rotating member 1214 is rotatably mounted on the first tank 1212 and has a first discharge port 1211. The rotating member 1214 is configured to switch the discharge and stop of the first discharge port 1211 by rotating an angle and / or rotating direction. The first discharge device 123 includes a drive motor 1231 for driving the rotating member 1214 to rotate.

[0061] During discharge, the drive motor 1231 outputs torque to drive the rotating component 1214 to rotate in a preset manner, switching the first discharge port 1211 to the discharge state, allowing the raw material in the first tank 1212 to be discharged from the first discharge port 1211. Similarly, the drive motor 1231 can also output torque to drive the rotating component 1214 to rotate, stopping the discharge from the first discharge port 1211. Thus, by controlling the drive motor 1231, the discharge and stop of the first storage unit 121 can be controlled.

[0062] The rotating component 1214 can be implemented using various structures. In some embodiments, the rotating component 1214 is a rotatable valve body with a built-in flow channel. Its working position is switched by circumferential rotation. When rotated to a first preset angle (e.g., 0°), its built-in flow channel is open, allowing raw materials to be discharged from the first outlet 1211. When rotated to a second preset angle (e.g., 90°), the built-in flow channel is blocked, stopping the discharge. In some embodiments, the rotating component 1214 is a disc gate embedded in the bottom of the first tank 1212. The fan-shaped notch at its edge overlaps with the outlet of the first tank 1212, and the effective opening area of ​​the overlapping area continuously changes with the rotation angle of the rotating component 1214. For example, it is completely misaligned (fully closed) at 0° and completely overlapped (fully open) at 90°. The flow rate can be precisely adjusted by controlling the rotating component 1214 to stop at any angle between 0° and 90° using the drive motor 1231. In some embodiments, the outer wall of the rotating component 1214 is provided with external threads and is threadedly engaged with the piston inside the first tank 1212. When the rotating component 1214 rotates, it drives the piston to move axially, pushing the raw material out of the first discharge port 1211 to achieve quantitative discharge. Figure 6, Figure 7 , Figure 8 In some embodiments shown, the first discharge device 123 is mounted on the lifting device 12. The first discharge device 123 includes one or more clutch structures 1232, each clutch structure 1232 corresponding to each first storage unit 121.

[0063] In embodiments not shown, the first discharge device 123 may also be installed on the housing 11 and not move with the lifting device 12, thereby reducing the overall weight of the lifting device 12. In some more specific embodiments, the first discharge device 123 includes one or more transmission interfaces capable of outputting torque. When the lifting device 12 is in the second position, the rotating parts 1214 of each first storage unit 121 can be inserted into the corresponding transmission interface and form a mechanical coupling, so that the first discharge device 123 can drive the rotating parts 1214 to rotate through the transmission interface, thereby switching the discharge and stop of the first discharge port 1211. In some more specific embodiments, the first discharge device 123 includes one or more longitudinally arranged rotating shafts. An axial sliding fit structure (such as a spline shaft and spline sleeve) is provided between the rotating shaft and the corresponding rotating part 1214. During the longitudinal movement of the lifting device 12, the rotating part 1214 can slide axially along the rotating shaft and continuously maintain power transmission, thereby realizing controlled discharge of the first storage unit 121 at any height.

[0064] The clutch structure 1232 includes an input terminal 12322, an output terminal 12321, and a clutch part. The input terminals 12322 of all clutch structures 1232 are directly or indirectly coupled to the output shaft of the drive motor 1231. The output terminals 12321 of each clutch structure 1232 are coupled to the rotating component 1214 of the corresponding first storage unit 121. The clutch part can respond to the input control signal to establish or disconnect power transmission between the input terminals 12322 and the output terminals 12321.

[0065] The first discharge device 123 can rise and fall together with the lifting device 12, thereby maintaining its relative position to each first storage unit 121 and establishing a direct power transmission path. By setting a clutch structure 1232 coupled between the drive motor 1231 and the rotating component 1214, selective discharge from multiple first storage units 121 can be achieved in an electronically controlled manner. Furthermore, it is also possible to simultaneously control the discharge of multiple first storage units 121 with a single drive motor 1231, effectively reducing the number of drive devices and lowering the overall complexity and manufacturing cost of the machine.

[0066] In other embodiments not shown, each first storage unit 121 may be equipped with an independent drive motor 1231, so that each drive motor 1231 directly establishes a power coupling relationship with the corresponding first storage unit 121. By controlling the start and stop of the corresponding drive motor 1231, a specific first storage unit 121 can be selectively started to perform material discharge. This scheme allows multiple first storage units 121 to work independently under mutual control, supporting not only individual material discharge on demand, but also simultaneous material discharge from multiple first storage units 121 without interference between them.

[0067] In such Figure 7 and Figure 8 In some more specific embodiments shown, the output shaft of the drive motor 1231 is provided with a first gear 12311, the input end of each clutch structure 1232 includes a second gear 12322, and multiple second gears 12322 mesh with the first gear 12311 simultaneously.

[0068] Since multiple second gears 12322 are always engaged with the first gear 12311, switching of power transmission does not require changing the mechanical connection. The material discharge process of each first storage unit 121 can be selectively controlled simply by controlling the engagement or disengagement of the clutch via electronic control. This method eliminates the complex structure of multiple motors and multiple shafts, which helps to simplify the wiring and size of the device.

[0069] Furthermore, the above implementation also supports simultaneous discharge from multiple first storage units 121. In some formulations, the target quantities of different raw materials overlap; for example, first storage units A, B, and C require discharges of 30, 40, and 50 units, respectively. During the discharge process, all three are first discharged in parallel to 30 units. Then, the power transmission of the clutch structure 1232 of first storage unit A is disconnected. First storage units B and C continue to discharge in parallel to 40 units. The power transmission of the clutch structure 1232 of first storage unit B is then disconnected. First storage unit C continues to discharge to 50 units. The power transmission of the clutch structure 1232 of first storage unit C is then disconnected, completing the discharge process. This parallel discharge mode significantly reduces the total discharge time, improves efficiency while ensuring accuracy, and is particularly suitable for applications with many types of raw materials, complex formulations, and large discharge volumes.

[0070] In some specific embodiments, the feeding device 10 is used to prepare the dye to obtain a dyeing composition for the user to use for hair dyeing. There are three first storage units 121, each containing raw materials corresponding to three primary color dyes. Primary color dyes refer to the three color dyes corresponding to the three primary colors. According to the principle of primary colors, any color can be represented as a proportional combination of the three primary colors. Therefore, by precisely controlling the output amount of each primary color dye, any color desired by the user can be prepared.

[0071] The feeding device 10 in various embodiments of this application has high discharge accuracy, thus using only three base color dyes to mix and blend any target color, meeting personalized hair dyeing needs. In the prior art, to obtain a target color, it is often necessary to combine more than ten or even dozens of color dyes. The solution of this application significantly reduces the types of color dyes required, requiring only three first storage units 121 to meet the requirements. On the one hand, it reduces cost and structural complexity; on the other hand, it only requires three first storage units 121 to be set on the lifting device 12, thereby avoiding the problem of overloading the lifting device 12 due to loading too much raw material, ensuring the practicality of the feeding device 10.

[0072] like Figure 1a , Figure 9 , Figure 10 In some embodiments shown, the feeding device 10 further includes a second storage unit 14, a second discharge device 144, a second discharge port 1216, and a flexible pipeline 143. The second storage unit 14 is mounted on the housing 11, and the second discharge port 1216 is mounted on the lifting device 12. When the lifting device 12 is in the second position, the second discharge port 1216 can deliver raw materials into the discharge area A. The flexible pipeline 143 connects the second discharge device 144 and the second discharge port 1216 to transport the raw materials.

[0073] The second discharge device 144 is directly or indirectly connected to the second storage unit 14 and is used to control the discharge and stop of the second storage unit 14. When the second storage unit 14 discharges, the raw material is output from the second storage unit 14 and moves along the flexible pipeline 143 to the second discharge port 1216. After leaving the second discharge port 1216, it falls into the container 20 in the discharge area A below. The specific structure of the second discharge device 144 is not the focus of this application, and it can be implemented using a peristaltic pump, centrifugal pump, gear pump, vacuum pump, etc.

[0074] The difference between the first storage unit 121 in the aforementioned embodiments and the second storage unit 14 is that it is designed to be fixedly installed on the housing 11 and connected to the second discharge port 1216 located on the lifting device 12 via a flexible pipe 143. When the lifting device 12 moves between the first position and the second position, the second storage unit 14 does not move with it.

[0075] In practical applications, the formula executed by the feeding device 10 may contain multiple raw materials, and the requirements for the discharge accuracy of different raw materials vary significantly. Among them, the accuracy of the dosage of some key raw materials is directly related to the functional performance of the composition, and even a slight error may affect the final result; while the dosage of other raw materials, even if there is a certain deviation, will not have a significant impact on the composition.

[0076] Taking hair dye as an example, the actual amount of each color dye added directly affects the color of the dyeing composition, thus requiring high precision in the dispensing process. However, non-coloring auxiliary materials are often added to the dyeing composition, typically including hydrogen peroxide, matrix, and conditioning agents. Hydrogen peroxide, primarily composed of hydrogen peroxide (H2O2), triggers the oxidation of precursors in the color dye to achieve color development, and bleaches (decolorizes) the hair's natural pigments, providing a better foundation for dyeing. The matrix aims to provide a suitable texture so that the components can be evenly dispersed; its main components are water, emulsifiers, thickeners, alcohols, propylene glycol, and other organic solvents. Conditioning agents protect the hair and reduce damage during the dyeing process. These non-coloring auxiliary materials do not directly affect the color of the dyeing composition; fluctuations in their dosage within a reasonable range have limited impact on the dyeing effect, and the precision requirements for their dispensing are relatively low.

[0077] The second storage unit 14 is used to accommodate the raw materials with relatively low requirements for feeding accuracy. It does not move with the lifting device 12, which can reduce the load on the lifting device 12. At the same time, since the second storage unit 14 is fixedly installed in the housing 11, it can be designed with a larger volume, which is suitable for long-term use, reduces the frequency of feeding or replacement, and improves the continuous working capability of the feeding equipment 10 and the user experience.

[0078] In some embodiments, there are multiple second storage units 14, each used to hold a variety of raw materials. In other embodiments, for multiple raw materials with lower requirements for discharge accuracy, they can be pre-mixed into a combined raw material according to a set ratio, and stored and discharged uniformly through a single second storage unit 14, thereby effectively reducing the types and number of second storage units 14, simplifying the system, and reducing usage and maintenance costs.

[0079] It should be noted that the type of raw material does not constitute a structural limitation on the first storage unit 121 or the second storage unit 14, nor does it serve as a criterion for distinguishing between the two. For example, for raw materials with relatively low discharge accuracy requirements, discharge can still be carried out through the first storage unit 121. The design distinction between the first storage unit 121 and the second storage unit 14 does not depend on the properties of the raw material, but is the result of functional optimization based on comprehensive considerations such as accuracy control, the load on the lifting device 12, and maintenance frequency in actual use.

[0080] In some embodiments, the second storage unit 14 may be fixed to the housing 11 or formed directly as a part of the housing 11. The user directly adds raw materials to the second storage unit 14. In other embodiments, the second storage unit 14 is detachably mounted to the housing 11 for easy replacement during use. When the raw materials in the storage unit are depleted, the user can disassemble the entire storage unit and replace it with a new unit of the same type, achieving quick plug-and-play functionality.

[0081] In such Figure 2a and Figure 9 , Figure 10 In some more specific embodiments shown, the second storage unit 14 includes a second tank 141 and a seal 1421. The second tank 141 may have a second receiving cavity 145 and a tank opening 142, and the seal 1421 is located at the tank opening 142 for sealing the tank opening 142.

[0082] The housing 11 is provided with a trigger structure 115, which is configured such that when the second storage unit 14 is installed in place with the can opening 142 facing downward, the trigger structure 115 triggers the seal 1421 to release the seal on the can opening 142.

[0083] The second storage unit 14 adopts a bottom discharge type, which allows the raw materials to flow out smoothly under the action of gravity, effectively reducing the residue of raw materials on the inner wall of the second tank 141 and related conveying paths. The seal 1421 can prevent raw material leakage during the installation of the second storage unit 14.

[0084] When the second storage unit 14 is installed in place with the housing 11, the triggering structure 115 on the housing 11 acts on the seal 1421, releasing it from the seal on the tank opening 142, allowing the second storage unit 14 to discharge material as needed. The triggering structure 115 ensures that the second storage unit 14 can only discharge material after it is correctly installed in place, avoiding material leakage caused by human error or equipment malfunction.

[0085] In some specific embodiments, the seal 1421 can be a disposable sealing film or a destructible cover. The trigger structure 115 can be a component with a pointed tip. During the installation of the second storage unit 14, the pointed tip of the trigger structure 115 pierces the seal 1421, thereby releasing the seal.

[0086] In such Figure 10 and Figure 11 In some more specific embodiments shown, the seal 1421 is movably mounted on the can opening 142 and is movable between a sealed position and a discharge position. When the seal 1421 is in the sealed position, it seals the can opening 142; when the seal 1421 is in the discharge position, it releases the seal on the can opening 142. Figure 11 The diagram shows a seal 1421 located at the discharge position. The second storage unit 14 also includes a return structure (not shown) for maintaining the seal 1421 in the sealed position when not subjected to other external forces. The return structure may specifically be a spring, a spring sheet, or a similar structure.

[0087] The trigger structure 115 protrudes upward. When the second storage unit 14 is installed into the housing 11, the trigger structure 115 inserts into the can opening 142 and pushes the seal 1421 upward from the sealed position to the discharge position, thereby releasing the seal of the can opening 142. Figure 11 The state is shown in the diagram. The above triggering process does not depend on user operation and is completed synchronously with the installation process of the second storage unit 14, making it convenient to operate.

[0088] When the second storage unit 14 is disassembled, as the user removes the second storage unit 14 from the housing 11, the trigger structure disengages from the can opening 142, and the seal 1421 returns to the sealing position under the action of the return structure and reseals the can opening 142. If there is still raw material remaining inside the second storage cavity 145, the automatic reset of the seal 1421 can prevent raw material from leaking into the housing 11 during the disassembly of the second storage unit 14, improving cleanliness and facilitating the overall maintenance of the feeding equipment 10.

[0089] In such Figure 11 In the more specific embodiment shown, the diameter of the second tank 141 at the opening 142 is significantly smaller than that of the other parts. The seal 1421 has a through-channel 1411 inside, with one end of the through-channel 1411 connected to the outside as a discharge end and the other end as a feed end. When the seal 1421 is in the sealed position, the feed end of the through-channel 1411 is in contact with the inner wall of the opening 142, preventing raw materials from entering the feed end, thus achieving a seal. When the seal 1421 moves to the discharge position, i.e. Figure 11 As shown, the feed end moves into the interior of the second tank 141 and separates from the inner wall of the tank opening 142. At this time, the raw material can enter the feed end and flow out of the second storage cavity 145 from the discharge end along the through channel 1411, thereby realizing the discharge process of the second storage unit 14.

[0090] like Figure 9 , Figure 10 , Figure 11 In some embodiments shown, the housing 11 is provided with a vertically extending guide tube 115. One end of the guide tube 115 protrudes upward and forms the aforementioned trigger structure, while the other end of the guide tube 115 is connected to the second discharge device 144. The second discharge device 144 is connected to the second discharge port 1216 via a flexible conduit 143. When the second storage unit 14 is installed in place, the guide tube 115 is inserted into the tank opening 142, triggering the seal 1421 to release the seal. The raw material output from the second storage cavity 145 can then enter the second discharge device 144 along the guide tube 115. Therefore, the guide tube 115 simultaneously performs the dual functions of releasing the seal and conveying the raw material, effectively simplifying the structure and improving assembly efficiency.

[0091] In some implementations, such as Figure 3 , Figure 9 , Figure 10 As shown, the housing 11 has a second mounting cavity 113, which is cylindrical and has a through hole at its bottom. A trigger structure is located below the through hole. The second can 141 is cylindrical and can be inserted into the second mounting cavity 113, with the can opening 142 passing through the through hole. A second cover 116 is mounted on the housing 11 and can be opened and closed. The second cover 116 changes state in response to user operation; when closed, it seals the second mounting cavity 113, and when opened, it exposes the second mounting cavity 113 to facilitate user replacement of the second storage unit 14. The cylindrical fit allows for natural radial positioning and guidance, ensuring that the second storage unit 14 is always vertically aligned with the guide tube 115 during insertion, thus accurately aligning the can opening 142 with the guide tube 115 when inserted into place.

[0092] In such Figure 12a , Figure 12b , Figure 13a , Figure 13b In some embodiments shown, the feeding device 10 includes a sealing structure 131 mounted on the housing 11. The sealing structure 131 is configured to seal one or more discharge ports 1211 when the lifting device 12 is in the first position. It should be noted that in the following description of various embodiments of the sealing structure 131, discharge port 1211 may refer to either the first discharge port 1211 mentioned above or the second discharge port 1216. There is no essential difference between the two in their cooperation with the sealing structure 131; both can perform the functions of sealing and releasing the seal. For simplicity, the first discharge port 1211 and the second discharge port 1216 will no longer be distinguished in the description and will be collectively referred to as discharge port 1211.

[0093] like Figure 12b , Figure 13a , Figure 13b As shown, when the lifting device 12 is in the first position, the sealing structure 131 seals each discharge port 1211, preventing foreign matter such as air, moisture, and dust from entering the discharge port 1211 and contaminating the raw materials when the feeding equipment 10 is not in operation. This helps extend the usable time of the raw materials and improves the overall sealing and storage safety of the equipment. Figure 12a , Figure 12b As shown, when the lifting device 12 rises to the second position, each discharge port 1211 is disengaged from the sealing structure 131 and exposed above the discharge area A, enabling the aforementioned discharge process to be carried out.

[0094] The sealing and unsealing process of each discharge port 1211 is synchronized with the working and non-working states of the feeding device 10. Specifically, when the feeding device 10 is in a non-working state, the lifting device 12 is in the first position, at which time the sealing structure 131 automatically closes one or more discharge ports 1211 without additional user operation. When the device enters the working state, the lifting device 12 rises to the second position, and each discharge port 1211 disengages from the sealing structure 131, ensuring that the raw materials can be fed smoothly.

[0095] In some more specific embodiments, each discharge port 1211 is located on the lower end face of the lifting device 12, and the sealing structure 131 is located below the lifting device 12; during the process of the lifting device 12 descending to the first position, the discharge port 1211 abuts against the sealing structure 131 to achieve sealing, thereby blocking the conveying path and achieving the closure of the discharge port 1211.

[0096] In some embodiments not shown, the discharge port 1211 is disposed on the side wall of the lifting device 12 and faces horizontally (e.g., horizontally outward). Correspondingly, the sealing structure 131 is disposed on the side of the lifting device 12 in the first position, and when the lifting device 12 is in the first position, the end face of the discharge port 1211 is tightly fitted with the sealing structure 131 to seal.

[0097] There are multiple ways to implement the sealing structure 131. For example... Figure 12b , Figure 15 As shown, in some specific embodiments, the sealing structure 131 includes a flexible component 1311, and the outlet 1211 abuts against the flexible component 1311 to achieve a seal. The flexible component 1311 refers to a component with a certain degree of elasticity and deformability, which can be formed from materials such as rubber, silicone, TPU (Thermoplastic Polyurethane), TPE (Thermoplastic Elastomer), and foam. When subjected to external force (such as the pressure of the outlet 1211), it can undergo localized deformation, conforming to the contact surface, thereby playing a sealing role in preventing the entry of external media such as gas, liquid, and dust, or the leakage of internal media. The flexible component 1311 can be an independently molded part, for example, processed by injection molding, die casting, extrusion, etc., and installed on other rigid structures by mechanical snaps, screws, adhesives, etc. The flexible component 1311 can also be a flexible layer formed directly on the surface of other rigid structures through processes such as injection molding, hot melting, and spraying.

[0098] like Figure 12b , Figure 15As shown, in some specific embodiments, the sealing structure 131 is provided with one or more sealing grooves 1313 corresponding to the positions of each discharge port 1211. When the lifting device 12 is in the first position, the discharge port 1211 is inserted into the corresponding sealing groove 1313. The sealing groove 1313 can spatially surround the discharge port 1211 and achieve a seal.

[0099] In such Figure 15 In some embodiments shown, the sealing structure 131 has both a flexible element 1311 and a sealing groove 1313, thus combining the advantages of both. Specifically, the sealing structure 131 includes a substrate 1312 and a flexible element 1311. One or more sealing grooves 1313 are provided on the upper surface of the substrate 1312, and the flexible element 1311 is mounted on the substrate 1312 and covers the upper surface of the substrate 1312.

[0100] Please refer to the above. Figure 13b As shown, when the lifting device 12 is in the first position, each discharge port 1211 squeezes the flexible member 1311 to deform it locally and enters the sealing groove 1313. The flexible member 1311 is compressed and produces controllable elastic deformation, filling the gap between the inner wall of the groove and the outer wall of the discharge port 1211, and wrapping the discharge port 1211 to achieve sealing.

[0101] By rationally designing the initial thickness, elastic modulus, and geometric dimensions of the sealing groove 1313 of the flexible component 1311, the flexible component 1311 can be installed without being difficult to insert due to excessive deformation or without causing poor sealing due to insufficient clamping force.

[0102] In some embodiments not shown, the flexible element 1311 is disposed within each sealing groove 1313, covering its sidewalls and bottom wall. Thus, after the discharge port 1211 is inserted into the sealing groove 1313, it can tightly seal against the flexible element 1311, and the discharge port 1211 does not undergo the process of "squeezing the flexible element 1311 to cause partial deformation and enter the sealing groove 1313," thereby reducing the damping when the lifting device 12 returns to the first position.

[0103] In some specific embodiments, the sealing structure 131 is detachably installed on the housing 11, facilitating its removal and cleaning by the user during daily use. When the sealing structure 131 is in contact with the discharge port 1211, raw materials can easily adhere to it; when the sealing structure 131 is not sealing the discharge port 1211, dust, moisture, and other impurities may settle on its surface, leading to a decrease in sealing performance or contamination of the discharge port 1211. The detachable design allows the user to easily remove the sealing structure 131 for thorough cleaning, ensuring that its sealing surface remains clean and effectively maintaining a long-term stable sealing effect.

[0104] In some specific embodiments, the sealing structure 131 is designed as a structure for placing the container 20, with its upper surface used to support the bottom of the container 20, thereby enabling the sealing structure 131 to perform multiple functions: like Figure 13a , Figure 13b As shown, when the lifting device 12 is in the first position, the discharge port 1211 moves down and abuts against the upper surface of the sealing structure 131 to form a sealed state.

[0105] like Figure 12a , Figure 12b As shown, when the lifting device 12 rises to the second position, the discharge port 1211 leaves the sealing structure 131, forming a discharge area A below the lifting device 12 and above the sealing structure 131. The sealing structure 131 serves as a support platform for the container 20, maintaining the stability of the container 20 throughout the discharge process. In conjunction with some of the aforementioned embodiments, the sealing structure 131 includes a flexible element 1311, which typically also possesses significant friction. When the container 20 is placed on the sealing structure 131, its bottom contacts the flexible element 1311. The friction generated by the flexible element 1311 prevents the container 20 from sliding or shaking during the discharge process, ensuring the stability of the container 20.

[0106] like Figure 14 , Figure 16 As shown, in some more specific embodiments, the sealing structure 131 is provided with guide protrusions 1314. When the container 20 is placed on the sealing structure 131, it is positioned by the guide protrusions 1314 such that the opening of the container 20 is located below one or more discharge ports 1211.

[0107] Since the discharge port 1211 is located below the lifting device 12, it may not be directly visible to the user under normal use. If the user fails to align the container 20 correctly when placing it, the raw material output from the discharge port 1211 may spill out instead of entering the container 20. The guide protrusion 1314 provided on the sealing structure 131 provides a clear positioning reference for the container 20, guiding the user to accurately place the container 20 in the preset position.

[0108] like Figure 13a , Figure 14 , Figure 18As shown, in some embodiments, the sealing structure 131 has a rectangular cross-section and can be installed on the housing 11 in either a first direction or a second direction, wherein the first direction is rotated 180° relative to the second direction. Furthermore, multiple sealing grooves 1313 are configured such that, when the sealing structure 131 is installed in either the first or second direction, it can align with the discharge port 1211 and achieve a seal. Thus, the sealing structure 131 can simultaneously accommodate two mutually rotating installation methods, ensuring the sealing grooves 1313 seal the discharge port 1211, thereby reducing the installation difficulty of the sealing structure 131.

[0109] like Figure 18 As shown, in some specific embodiments, multiple sealing grooves 1313a are arranged symmetrically, so that when the sealing structure 131 is installed in the first direction or the second direction, the outlet 1211 can be inserted into one of the corresponding symmetrical sealing grooves 1313a to achieve a seal. This method is suitable for situations where the distance between the outlet 1211 and the axis of symmetry m of the sealing structure 131 is relatively large, and the paired sealing grooves 1313a can accurately match the position of the outlet 1211, ensuring the reliability of the seal.

[0110] like Figure 18 As shown, in some specific embodiments, at least one sealing groove 1313b extends to cover the symmetrical first target position and second target position, such that when the sealing structure 131 is installed in the first direction or the second direction, the discharge port 1211 can be inserted into either the first target position or the second target position to achieve a seal with the sealing groove 1313b. This method is suitable for situations where the discharge port 1211 is close to the axis of symmetry m, saving space and simplifying the structure by covering two symmetrical positions with the extended sealing groove 1313b.

[0111] like Figure 18 In the actual embodiment shown, the above-mentioned sealing groove 1313a and sealing groove 1313b are both present, corresponding to the discharge port 1211 which is relatively far from the center and the discharge port 1211 which is close to the center, respectively.

[0112] like Figure 1a , Figure 1b , Figure 2a , Figure 2b , Figure 14 In some embodiments shown, the feeding device 10 includes a weighing device 13 that detects weight by gravity. The weighing device 13 includes a weighing pan 131 and a gravity detection component 132. The weighing pan 131 is located below the discharge area A. When the user places the container 20 into the discharge area A during the operation of the feeding device 10, the container 20 is positioned precisely on the weighing pan 131. The gravity detection component 132 is coupled to the weighing pan 131 and is capable of measuring the weight of the container 20.

[0113] The gravity detection component 132 measures the weight of container 20 before and after each discharge. The weight change corresponds to the actual amount of raw material fed into the current discharge cycle. By comparing this weight with the preset target amount, it can be determined whether the discharge meets the target. If the target is not met, feeding can continue; if the target is met, discharge stops, thus achieving closed-loop control of the discharge process for each type of raw material. This method eliminates the need for complex flow sensors in the conveying path, relying solely on the overall weight change of container 20 for judgment. It features a simple structure, timely response, and high accuracy, making it particularly suitable for scenarios involving the continuous feeding of multiple raw materials, effectively improving the consistency and accuracy of the discharge.

[0114] In addition, in conjunction with some of the aforementioned implementation methods, such as Figure 5 and Figure 6 As shown, the rotating component 1214 of the first storage unit 121 is driven to rotate by the drive motor 1231, correspondingly switching the discharge and stop of the first discharge port 1211. The discharge time of the first discharge port 1211 can be precisely controlled by controlling the rotation angle and running time of the drive motor 1231, thereby corresponding to the discharge amount of raw materials. This control process can cooperate with the weight measurement results of the metering device 13. The initial quantitative discharge of raw materials is achieved by controlling the drive motor 1231, and then real-time feedback and correction are performed based on the weight measurement results of the metering device 13, forming a discharge control scheme that is both fast and highly accurate. The two work together and compensate for each other, ensuring timely discharge response and ensuring that the final discharge amount is consistent with the target value, effectively improving discharge accuracy, mixing consistency and system stability.

[0115] In other embodiments not shown, the metering device 13 may also use a flow sensor to detect the instantaneous flow rate of the raw material in the conveying path and integrate it over the discharge time to calculate the actual amount dispensed; or it may use optical detection, visual recognition or other methods to identify the change in liquid volume or level in the container 20 to obtain the actual amount dispensed.

[0116] like Figures 14 to 17 In some more specific embodiments shown, the sealing structure 131 constitutes the aforementioned weighing pan 131. Specifically, the gravity detection assembly 132 includes a gravity sensor 1321 and a tray 1322. A connecting block 1323 is provided below the tray 1322, and the connecting block 1323 is mounted on the detection end of the gravity sensor 1321. The sealing structure 131 is detachably mounted on the upper surface of the tray 1322.

[0117] The tray 1322 has a certain supporting area, which can stably support the sealing structure 131 and the container 20 placed on it, ensuring accurate and reliable force transmission during the weighing process.

[0118] There are various ways to install the sealing structure 131 and the tray 1322. In some embodiments not shown, they can be installed by magnetic attraction or by means of clips, bolts, or other structures. Figure 16 and Figure 17 In some specific embodiments shown, a rectangular cavity 1315 is formed below the sealing structure 131, which allows the tray 1322 to be inserted and is positioned. The tray 1322 also has a rectangular cross-section. During installation, the sealing structure 131 is placed on top of the tray 1322, and the tray 1322 is placed into the rectangular cavity 1315 to complete the installation process.

[0119] In combination with the aforementioned implementation methods, the mutual installation of the rectangular cavity 1315 and the tray 1322 can realize two installation directions of the sealing structure 131. It is only necessary to confirm the long and short sides of the tray 1322 and the long and short sides of the rectangular cavity 1315, and determine the installation angle through geometric feature matching, making the installation process relatively easy.

[0120] like Figure 1a , Figure 1b , Figure 2a , Figure 2b , Figure 9 The illustrated embodiment provides a compact, high-precision, and easy-to-operate and maintain feeding device 10. This embodiment serves as an integrated description of the foregoing specific embodiments (including those described in "in some embodiments," "some embodiments," and "specific embodiments"), aiming to demonstrate the overall concept and composability of the features of the present invention. The overall structure, component functions, workflow, and technical advantages mentioned in this embodiment, as well as their specific implementation methods and technical details, have been detailed in the preceding related embodiments. It is particularly noteworthy that, to meet different application scenarios, without creating technical contradictions, any technical feature disclosed in any of the foregoing embodiments can be selectively combined and applied to other embodiments or to form new implementation methods, or to constitute a more specific implementation scheme or variant scheme of this embodiment.

[0121] The feeding device 10 in this embodiment includes a housing 11, a lifting device 12 installed on the housing 11, a plurality of first storage units 121, a first discharge device 123, a second storage unit 14, a second discharge device 144, and a metering device 13.

[0122] The housing 11 has a first mounting cavity 111 and a second mounting cavity 113 arranged vertically inside, and a hollow portion 114 connected to the first mounting cavity 111 is also provided on the housing 11.

[0123] The lifting device 12 is slidably installed in the first mounting cavity 111 and can move or stay at least between a first position, a second position, and a third position in between. The lifting device 12 is provided with a handle 125 on the top for the user to manually pull to change its position, and is provided with multiple first discharge ports 1211 and second discharge ports 1216 on the bottom.

[0124] The feeding device 10 has two structures for storing raw materials: a first storage unit 121 and a second storage unit 14. The former is detachably installed on the lifting device 12 and rises and falls with the lifting device 12, discharging directly downwards from the first discharge port 1211. The latter is detachably installed in the second mounting cavity 113 and does not rise and fall with the lifting device 12, but is connected to the second discharge port 1216 via a flexible pipe 143. The first storage unit 121 has a shorter conveying path, less raw material residue, and higher discharge accuracy, but it increases the weight of the lifting device 12 and is suitable for raw materials requiring high discharge accuracy. The second storage unit 14 has a longer conveying path and lower discharge accuracy compared to the first storage unit 121, but it does not increase the weight of the lifting device 12 and can be designed to have a larger storage capacity, making it suitable for raw materials requiring relatively lower discharge accuracy.

[0125] The measuring device 13 is located below the lifting device 12 and includes a gravity detection component 132 and a weighing pan 131. The weighing pan 131 includes a flexible element 1311. The weighing pan 131 serves to seal the first discharge port 1211 and the second discharge port 1216, and also provides a place for the container 20 to be placed. The gravity detection component 132 is coupled to the weighing pan 131 and is capable of measuring the weight of the container 20.

[0126] like Figure 2a , Figure 2b As shown, when the lifting device 12 is in the first position, the feeding device 10 is in a non-operating state. In this state, the multiple first discharge ports 1211 and the second discharge port 1216 are tightly attached to the weighing pan 131 and sealed, preventing foreign objects from entering the first discharge ports 1211 and the second discharge ports 1216, and also reducing the risk of the raw materials in the first discharge ports 1211 and the second discharge ports 1216 drying out and deteriorating due to contact with air. Furthermore, the lifting device 12 and the multiple first storage units 121 are all located in the first position with the lowest height, which makes the feeding device 10 have a low center of gravity and small size, making it easy to store and transport.

[0127] When the lifting device 12 rises to the second position, the feeding device 10 enters the working state. In this state, the multiple first discharge ports 1211 and second discharge ports 1216 are detached from the weighing pan 131 and are no longer sealed. A discharge area A is formed below the lifting device 12. Since the perforated part 114 connects to the first mounting cavity 111, the discharge area A is exposed. The user holds the container 20 through the perforated part 114 into the discharge area A and places it on the weighing pan 131. The raw materials fed out by the first discharge ports 1211 and second discharge ports 1216 fall into the container 20. After each feeding, the metering device 13 can know the actual amount of raw materials fed in that feeding based on the weight change of the container 20, thereby realizing closed-loop control of the discharge process. After all raw materials have been discharged, the user removes the container 20 from the discharge area A, completing the entire discharge process.
