Description

Technical Field

[0001] This utility model relates to the field of catering equipment technology, specifically to a pushing device in a dispensing device. Background Technology

[0002] With the improvement of living standards, the intelligentization of catering equipment, whether for commercial or household use, is attracting increasing attention. Among them, automatic sauce machines are food processing equipment that uses automated control to precisely, hygienically, and efficiently extrude viscous, semi-fluid, or particulate sauces, pastes, fillings, etc., to designated locations.

[0003] For example, Chinese patent document CN217792712U discloses a sauce dispensing device, a sauce machine, and a stir-fry machine. The sauce dispensing device includes a container holding sauce, a pressing head connected to the container to extrude the sauce, and a driving device for moving the pressing head. The pressing head includes a connecting part and a dispensing pipe. The driving device includes a pressing rod for pressing connection, an adjusting rod extending vertically, a rotating rod connected to the connecting part, and a pivot shaft disposed in the middle of the rotating rod. The adjusting rod abuts against the end of the rotating rod away from the connecting part. The pressing head has a first state of being inclined, and a second state of being rotated vertically by the adjusting rod. When the pressing head is in the second state, the pressing rod presses against the dispensing pipe to extrude the sauce. This prior art uses pump technology, which utilizes negative pressure to pump upwards and deliver the sauce, but it cannot precisely control the amount of sauce output by the pump.

[0004] For example, Chinese patent document CN110775543B discloses a sauce making machine, including: a main unit and a sauce cup connected to the main unit. The main unit includes: a frame, a screw mounted on the frame, a driver connected to the screw, and a baffle plate mounted on the frame. The frame is provided with a receiving pipe; the screw is housed in the receiving pipe; the baffle plate is located at the outlet end of the receiving pipe. The sauce cup includes: a cup body and a stirring blade installed in the cup body. The cup body has a discharge port, which connects to the outlet end of the receiving pipe, and the stirring blade is connected to the driver. The above-mentioned sauce making machine can achieve closed storage of sauce using the sauce cup, and uses the driver to drive the stirring blade and screw to rotate to drive the sauce to be discharged evenly. This prior art uses a screw to scrape out the sauce and mainly relies on the gravity of the sauce for discharge, which still cannot achieve a relatively accurate quantitative discharge.

[0005] To achieve quantitative dispensing, existing technologies utilize peristaltic pumps. For example, utility model patent CN212213443U discloses an assembly structure for a drum-type stir-fry machine, which includes a stir-frying mechanism; a main ingredient feeding mechanism for supplying main ingredients to the stir-frying mechanism; a sauce feeding mechanism for supplying sauces to the stir-frying mechanism; a bowl and plate feeding mechanism for transferring cooked food to bowls; a rinsing mechanism for rinsing the food after stir-frying; and a control mechanism for controlling the main ingredient feeding mechanism. The machine features fully automated operation of its ingredient feeding mechanism, sauce feeding mechanism, stir-frying mechanism, dish feeding mechanism, and rinsing mechanism. The stir-frying mechanism includes at least two cooking stations, each equipped with a roller and a heating element. The roller rotates around its own axis via a first rotating mechanism to provide uniform heating and stirring. The roller also rotates up and down around its axis via a second rotating mechanism to add main ingredients, sauces, and vegetables, and to rinse the food. This allows for the step-by-step addition of main ingredients and sauces, as well as batch and fully automated stir-frying. The sauce feeding mechanism uses a peristaltic pump for quantitative addition; the control mechanism calculates when the sauce is about to run out after a certain number of additions.

[0006] However, long-term use will cause corrosion, adsorption, and aging of the peristaltic pump hose, leading to changes in the hose diameter and thus inaccurate metering; if used as a disposable pump, it will greatly increase costs. Utility Model Content

[0007] The purpose of this utility model is to provide a pushing device in a discharging device, which partially solves or alleviates the above-mentioned deficiencies in the prior art. By designing a multi-level nested and easily disassembled telescopic mechanism, quantitative discharging of sauce is achieved.

[0008] To solve the aforementioned technical problems, the present invention specifically adopts the following technical solution: A pushing device in a discharge device, the discharge device comprising: a storage hopper, the pushing device being disposed on top of the storage hopper, and the pushing device comprising: a multi-stage telescopic mechanism coaxially nested therein, wherein... The primary telescopic mechanism connected to an external drive device includes: a first rotating rod connected to the drive device, a first housing threadedly connected to the first rotating rod, and the first housing having a thread at a first end near the drive device; The final telescopic mechanism for pushing materials includes: a second housing, the inner wall of which is provided with an internal thread extending from the top to the bottom, a second rotating rod that is threadedly connected to the internal thread inside the second housing; and a pushing rod at the bottom of the second housing. The second housing is fitted inside the first housing and can slide along the axial direction of the first housing; the first rotating rod is fitted inside the second rotating rod and the second rotating rod can slide along the axial direction of the first rotating rod. When the external drive device drives the first rotating rod to rotate, the first rotating rod drives the second rotating rod to rotate synchronously, so that the first housing slides along the axial direction of the first rotating rod, and at the same time the second housing slides along the axial direction of the second rotating rod.

[0009] Furthermore, the pushing device also includes: an extrusion member that can slide axially along the inner wall of the storage barrel; the extrusion member includes a first outer wall that can fit against the inner wall of the storage barrel, a first protrusion connected to the inner wall of the first outer wall is provided in the space enclosed by the first outer wall, a second protrusion is formed by extending the end of the first protrusion away from the first outer wall in a direction away from the pushing device, a first cavity is formed between the second protrusion and the first outer wall, and the middle part of the second protrusion is recessed in a direction close to the pushing device to form a frustum-shaped second cavity, a first limiting groove is provided on the side of the second cavity close to the pushing device, and a pushing rod fitted in the first limiting groove is provided at the bottom of the second housing.

[0010] Furthermore, the pushing device also includes: at least one intermediate telescopic mechanism, the intermediate telescopic mechanism including: a third housing, the first end of the third housing being threadedly connected to a third rotating rod; The third housing is sleeved between the first housing and the second housing, and the third rotating rod is sleeved between the first rotating rod and the second rotating rod; When the driving device drives the first rotating rod to rotate, the first rotating rod drives the second rotating rod and the third rotating rod to rotate synchronously, so that the first housing slides along the axial direction of the first rotating rod, and at the same time, the third housing slides along the axial direction of the first housing, and the third rotating rod slides along the axial direction of the first rotating rod. Simultaneously, the second rotating rod slides along the axial direction of the third rotating rod, and the second housing slides along the axial direction of the third housing, so that the push rod at the bottom of the second housing pushes the extruder.

[0011] Furthermore, the pushing device also includes: an outer shell sleeved outside the first housing, the outer shell being disposed on the top of the storage hopper, the outer surface of the first housing having a protrusion along the axial direction of the first housing, and the inner wall of the outer shell having a groove along the axial direction of the outer shell.

[0012] Furthermore, the outer surface and inner wall of the third housing and the third rotating rod are respectively protrusions and grooves along the axial direction of the third housing, and the third rotating rod is snap-fitted to the first rotating rod and the second rotating rod respectively; The outer surface of the first rotating rod is provided with a protrusion along the axial direction of the first rotating rod, and the inner wall of the second rotating rod is provided with a groove along the axial direction of the second rotating rod, and the protrusion and the groove are snap-fitted together.

[0013] Furthermore, a rotating component is coaxially disposed at the top of the first rotating rod, and an elastic component is disposed between the rotating component and the first rotating rod.

[0014] Furthermore, a plurality of reinforcing ribs are provided on the side of the boss wall between the first cavity and the second cavity near the third housing.

[0015] Furthermore, the top of the first rotating rod is provided with a limiting mechanism for restricting the unidirectional rotation of the first rotating rod. The limiting mechanism includes: a ratchet provided on the top of the first rotating rod, and at least one limiting pawl provided on the top of the housing and engaging with the ratchet.

[0016] Furthermore, the outer shell is detachably connected to the storage tank.

[0017] Furthermore, the outer shell is provided with a limiting protrusion.

[0018] Beneficial effects: Existing technologies employ pump-assisted negative pressure feeding or utilize the sauce's own gravity for dispensing, which cannot achieve precise micro-volume dispensing. To achieve precise quantitative dispensing, peristaltic pumps are also used. However, with prolonged use, the hoses of peristaltic pumps are prone to corrosion and aging, leading to inaccurate dispensing. Furthermore, using them as disposable items significantly increases costs. Therefore, the dispensing device in this application utilizes multiple coaxially nested multi-stage telescopic mechanisms made of plastic, along with a corresponding storage tank and extruder. Based on the threaded transmission between the multi-stage telescopic mechanisms, the length of the pushing device extends progressively. The pushing rod at the bottom of the third housing of the final telescopic mechanism pushes the extruder to move within the storage tank, causing the paste-like sauce to be ejected from the dispensing nozzle in a micro-volume. Moreover, because the storage tank and pushing device are made of plastic, the manufacturing cost is greatly reduced, allowing the entire dispensing device to be replaced as a single unit as a disposable consumable without complex cleaning or component maintenance, thus avoiding sauce contamination due to inadequate cleaning.

[0019] As the sauce in this application is a concentrated sauce, the control of the output (micro-volume) needs to be very precise. It is also necessary to ensure that the micro-volume output is accurate even when the amount of sauce remaining in the storage tank is small. In other words, the entire output process needs to ensure a stable micro-volume output. Therefore, the discharging device of this application sets up a storage tank and a sealing film at the discharging end of the storage tank. At the same time, a slightly deformable extruder is set up inside the storage tank. The extruder and the film form a sealed storage space. Multiple coaxially nested multi-stage telescopic mechanisms are set up to drive the extruder to move and undergo slight deformation, thereby achieving micro-discharging. For example, based on the threaded transmission between the multi-stage telescopic mechanisms, the length of the pushing device extends step by step. The pushing rod at the bottom of the third housing of the last telescopic mechanism pushes the extruder to move in the storage tank. The extruder causes the paste sauce to be sprayed out from the opening gap of the film at the discharging nozzle with a micro-volume or weight (the specific amount can be determined by controlling the rotation angle or number of revolutions of the motor to determine the extension length of the multi-stage telescopic mechanism, thereby achieving quantitative discharging). When the extruder slightly deforms and resets, the negative pressure formed causes the opening gap of the film to close again, and can prevent sauce residue or excess dripping at the nozzle, thereby ensuring accurate micro-discharging. Furthermore, the use of a multi-stage telescopic mechanism is more conducive to the miniaturization of the sauce machine and the full utilization of its internal space.

[0020] The final telescopic mechanism of the discharge device in this application, namely the second housing, adopts an assembly method of internal full thread and rotating rod, and a limiting groove is set on the extruder to limit the push rod of the second housing, thereby ensuring the stability between the housing and the extruder, thus ensuring the stability of micro-discharge, and preventing the inability to accurately discharge micro-volume due to the flexibility of the connection between the multi-stage telescopic mechanisms, or when the remaining amount of sauce in the storage tank is small, giving each component a large space for movement; at the same time, the first outer wall and the second protrusion of the extruder form a first cavity, and the middle part of the second protrusion is recessed to form a second cavity (in the initial state, that is, before the start of discharge, the two cavities are not filled with sauce, so there is a certain amount of gas in the two cavities). When the extruder is about to be squeezed, due to the action of the first protrusion and the reinforcing rib, the second protrusion can undergo slight deformation, thereby discharging micro-volume under the action of the two cavities, and the extruded sauce is retracted due to the cooperation of the second cavity and the first cavity, preventing residual sauce or excess dripping from the nozzle. Furthermore, the use of a multi-stage telescopic mechanism is more conducive to the miniaturization of the sauce machine and the full utilization of its internal space. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] In this document, suffixes such as "module," "part," or "unit" used to denote elements are used only for the purpose of illustrative purposes and have no specific meaning in themselves. Therefore, "module," "part," or "unit" can be used interchangeably.

[0026] In this document, the terms "upper," "lower," "inner," "outer," "front," "rear," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In this document, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this document, "and / or" includes any and all combinations of one or more of the listed related items.

[0029] In this article, "multiple" means two or more, that is, it includes two, three, four, five, etc.

[0030] As used in this specification, the term "about" typically means + / -5% of the value, more typically + / -4% of the value, more typically + / -3% of the value, more typically + / -2% of the value, even more typically + / -1% of the value, and even more typically + / -0.5% of the value.

[0031] In this specification, certain embodiments may be disclosed in a range-bound format. It should be understood that this "range-bound" description is merely for convenience and brevity and should not be construed as a rigid limitation on the disclosed range. Therefore, the description of a range should be considered as having specifically disclosed all possible subranges and the individual numerical values ​​within those ranges. For example, a description of the range 1-6 should be considered as having specifically disclosed subranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., and the individual numbers within those ranges, such as 1, 2, 3, 4, 5, and 6. This rule applies regardless of the breadth of the range.

[0032] Existing sauce machines use a motor-driven push rod to extrude sauces. This method is difficult to achieve micro-extrusion, such as extruding at least 1g per batch, or requiring a high-precision, high-performance motor, resulting in high costs. Furthermore, existing sauce machines are designed for sauces that can be directly added to food, such as soy sauce and vinegar. This application, however, targets specially formulated concentrated sauces. Because only biological preservatives are added, the shelf life is short, and being a concentrated sauce, the amount needed for each cooking session is even smaller, for example, at least 1g per batch (the exact amount varies depending on the amount of food cooked). Additionally, the sauce needs to be diluted after extrusion (and mixed if multiple sauces are needed simultaneously). However, existing sauce machines only extrude the sauce without considering long-term preservation or dilution and / or mixing. In view of this, this application proposes a method that can achieve long-term preservation, stable micro-quantitative dispensing, and dilute and / or mix the dispensed sauce, so that users can directly add the diluted and / or mixed sauce to food without manual dilution and / or mixing. Furthermore, to ensure the long-term preservation of the sauce in the dispensing device, a sealed dispensing space is formed by the sealing film at the extruder and the dispensing nozzle. To ensure stable dispensing throughout the entire process from a full tank to a small amount remaining, a nested multi-stage telescopic mechanism is used in conjunction with a specific extruder and a nozzle with a sealing film. This converts the rotation of the drive mechanism into linear motion, thereby pushing the extruder while causing a slight deformation to spray the sauce. Upon resetting, the interaction with the film creates a slight negative pressure, which reverses the adsorption of sauce at the nozzle, preventing sauce residue or dripping. In addition, by incorporating a full thread in the final stage of the multi-stage telescopic mechanism in conjunction with the upper limit structure of the extruder and the limiting structure on the machine frame, the highly flexible multi-stage telescopic mechanism is prevented from shifting or falling off, especially when the amount of sauce remaining is very small.

[0033] Furthermore, since concentrated sauce is used, the sauce in each storage tank is sufficient to support daily life for several months for families who cook frequently, and even a year for families who cook less. Therefore, to save costs and to avoid contamination of the sauce due to inadequate cleaning during reuse, the dispensing device in this application is made entirely of plastic, and the dispensing device is detachable (e.g., it can be quickly installed and removed using elastic elements), allowing the dispensing device to be quickly removed and used as a disposable consumable.

[0034] In this article, concentrated sauces refer to paste-like substances obtained by condiments commonly used in home cooking (including sour, sweet, and spicy seasonings) through a specific concentration process. For example, concentrated sweet sauces are sweeter or have a more intense sweetness than existing homemade sweet sauces. Therefore, to achieve the same level of sweetness, less concentrated sauce is needed compared to existing sweet sauces. Similarly, concentrated chili sauces are spicier or have a stronger spiciness than existing homemade chili sauces.

[0035] Example 1: This example proposes a pushing device in a discharge device. The discharge device includes a storage bin 102, the top of which is connected to a pushing device 101. The pushing device 101 includes a multi-stage telescopic mechanism coaxially nested together. (See [link to previous example]) Figure 3 .

[0036] In some embodiments, the primary telescopic mechanism connected to an external drive device includes: a first rotating rod 1015 connected to the drive device, and a first housing 1011 threadedly connected to the first rotating rod 1015. The first housing 1011 has a threaded connection at its first end near the drive device. (See also...) Figure 2 .

[0037] Specifically, the first rotating rod in this embodiment, as well as the second and third rotating rods in the following embodiments, are all screws.

[0038] In some embodiments, the final-stage telescopic mechanism for pushing materials includes: a second housing 1014, the inner wall of which is provided with an internal thread extending from the top to the bottom; a second rotating rod 1017 threadedly connected to the internal thread is provided inside the second housing 1014; and a pushing rod 1018 is provided at the bottom of the second housing 1014. (See also...) Figure 1 .

[0039] In some embodiments, the second housing 1014 is sleeved inside the first housing 1011 and can slide along the axial direction of the first housing 1011, the first rotating rod 1015 is sleeved inside the second rotating rod 1017, and the second rotating rod 1017 can slide along the axial direction of the first rotating rod 1011.

[0040] In this application, the final-stage telescopic mechanism is sleeved within the first-stage telescopic mechanism, and the two telescopic mechanisms are assembled by a sleeve connection. This structure and the flexible assembly method facilitate the replacement, maintenance, and assembly of the device. Furthermore, the interlocking design between the housings and between the rotating rods enables the miniaturization of the pushing device, facilitating its reasonable placement within limited spaces (such as within the mounting frame in the embodiments below).

[0041] The working principle of this embodiment is as follows: When the driving device 2 drives the first rotating rod 1015 to rotate, the first rotating rod 1015 drives the second rotating rod 1017 to rotate synchronously, so that the first housing 1011 slides along the axial direction of the first rotating rod 1015, and at the same time the second housing 1014 slides along the axial direction of the second rotating rod 1017.

[0042] In other embodiments, the discharge device further includes: an extrusion member that can slide axially along the inner wall of the storage bin; the extrusion member includes a first outer wall 1031 that can conform to the inner wall of the storage bin 102, a first protrusion 1034 connected to the inner wall of the first outer wall 1031 is provided in the space enclosed by the first outer wall 1031, the end of the first protrusion away from the first outer wall 1031 extends in a direction away from the pushing device 101 to form a second protrusion 1032, a first cavity is formed between the second protrusion 1032 and the first outer wall, and the middle part of the second protrusion is recessed in a direction close to the pushing device to form a frustum-shaped second cavity, a first limiting groove 1033 is provided on the side of the second cavity close to the pushing device 101, and a pushing rod 1018 fitted into the first limiting groove 1033 is provided at the bottom of the second housing 1014. See also Figure 9 .

[0043] In some embodiments, a plurality of reinforcing ribs are provided on the side of the boss wall between the first cavity and the second cavity near the third housing 1013.

[0044] In this embodiment, a first boss is provided, and a second boss connected to the first boss is provided. At the same time, multiple reinforcing ribs are provided so that the extruder can be displaced under the extrusion action of the push rod and generate a slight deformation. This deformation, along with the film on the discharge nozzle, works together to achieve spray discharge while preventing sauce residue or excess sauce from dripping from the nozzle.

[0045] In some embodiments, the pushing device 101 further includes: a housing 1012 sleeved outside the first housing 1011, the housing 1012 being disposed on the top of the storage tank 102, and the housing 1012 being detachably connected to the storage tank 102.

[0046] Specifically, a first housing and a second housing are fitted inside the outer casing 1012, and one end of the first rotating rod extends out of the outer casing 1012. A telescopic mechanism (the first-stage telescopic mechanism and the last-stage telescopic mechanism in this application, and the intermediate-stage telescopic mechanism in the following embodiments) is provided inside the outer casing, so that the telescopic mechanism extends along the axial direction of the outer casing, and the outer casing serves as an external protective shell to prevent displacement and damage to the telescopic mechanism.

[0047] Specifically, the housing is provided with a limiting protrusion. This limiting protrusion cooperates with the groove on the sauce machine where the dispensing device is installed (such as the groove on the mounting frame where the pushing device is installed in the embodiment below), ensuring that the pushing device 101 does not rotate with the rotation of the drive device.

[0048] In this embodiment, the first end of the first housing refers to the end position near the driving device. Preferably, the first housing, the second housing, and the third housing in the following embodiments are all hollow cylinders, wherein the first end of the first housing serves as the threaded connection portion with the first rotating rod. Specifically, the first end of the first housing is provided with a top cover, which has a through hole. The edge of the through hole extends downward to form an annular connecting surface, and the radius of the through hole is smaller than the radius of the first housing. Threads are provided on the connecting surface to achieve a threaded connection with the first rotating rod. The length of the thread on the connecting surface is much smaller than the length of the thread on the first rotating rod, so that the first rotating rod can be axially engaged with the second or third rotating rod. In addition, the second end of the first housing is an opening for fitting other housings and their corresponding rotating rods. The first rotating rod is threadedly connected to the connecting surface, causing the first housing to rotate axially along the first rotating rod.

[0049] The first outer shell serves as the primary telescopic mechanism, with its shell fitted onto the outermost shell. Therefore, a receiving space needs to be formed between the first shell and the first rotating rod. This receiving space can accommodate other shells (in this embodiment, the second shell of the final telescopic mechanism or the third shell of the intermediate telescopic mechanism in the following embodiments).

[0050] The third housing serves as the sleeve housing of the intermediate telescopic mechanism (in particular, the third housing and the third rotating rod of the intermediate telescopic mechanism mentioned in this embodiment refer to the third housing and the third rotating rod in the following embodiments). The connection structure between the housing and the rotating rod is the same as that of the first housing. The first end of the third housing refers to the end where the third housing sleeves the first housing and contacts the first end of the first housing.

[0051] The second housing, serving as the final stage of the telescopic mechanism, is fitted inside the outermost layer. The first end of the second housing is open, and a bottom cover is located at the bottom of the second end. A push rod with a raised structure extends from the middle of the bottom cover. The second end of the second housing can contact the extruding component. The internal threads of the second housing extend from its top to its bottom. The threaded connection between the housing and the rotating rod differs from that of the first and third housings. Since the push rod at the second end of the second housing pushes the extruding component, the interior of the housing is filled with internal threads, enhancing the stability between the rotating rod and the housing.

[0052] In this embodiment, the housings are assembled by a sleeve connection. This flexible assembly method has some impact on the accurate output of this pushing device. Therefore, the second housing and the second rotating rod (which is the part that directly contacts the extruder) are set to be internally threaded to ensure the stability of the discharge device.

[0053] In some embodiments, the inner wall of the first housing is provided with a protrusion along the axial direction, and the outer wall of the third housing is provided with a groove that can cooperate with the protrusion; or, the inner wall of the first housing is provided with a groove along the axial direction, and the outer wall of the third housing is provided with a protrusion that can cooperate with the groove; and / or, the inner wall of the outer shell is provided with a protrusion extending along the axial direction, and the outer wall of the first housing is provided with a groove.

[0054] In some embodiments, the outer surface of the first rotating rod 1015 is provided with a protrusion along the axial direction of the first rotating rod 1015, and the inner wall of the second rotating rod 1017 is provided with a groove along the axial direction of the second rotating rod 1017.

[0055] In this embodiment, the first rotating rod is sleeved inside the second rotating rod, and a snap-fit ​​method of protrusion and groove is provided to realize that the first rotating rod drives the second rotating rod to rotate.

[0056] Specifically, protrusions and grooves are provided on the housing to prevent relative rotation of the housing and to facilitate alignment and positioning during the installation of the housing.

[0057] Preferably, given that the pushing device in this application needs to be constantly replaced, and considering cost issues and reducing processing difficulty, the pushing device is made of plastic material, which is easier to injection mold.

[0058] In some embodiments, a limiting mechanism for restricting unidirectional rotation of the first rotating rod 1015 is provided at the top of the first rotating rod 1015. The limiting mechanism includes: a ratchet tooth disposed at the top of the first rotating rod 1015, and at least one limiting pawl disposed at the top of the housing 1012 and engaging with the ratchet tooth. See [link to relevant documentation]. Figure 2 .

[0059] In some embodiments, a rotating member 10152 is coaxially sleeved on the connecting end of the top of the first rotating rod 1015. The rotating member 10152 is rotatably connected to the driving device, and an elastic member is provided between the rotating member 10152 and the first rotating rod 1015. See [link to previous document]. Figure 2 .

[0060] Preferably, the top of the rotating member 10152 is connected to the transmission member 10151. The transmission member 10151 and the rotating member 10152 are engaged by a protrusion and a groove. The end of the transmission member 10151 away from the rotating member 10151 is provided with a groove that connects to the output end of the driving device. The driving device causes the transmission member 10151, the rotating member 10152 and the first rotating rod 1015 to rotate synchronously.

[0061] In particular, the middle part of the rotating part 10152 has an upward convex shape with a flat perimeter, which facilitates the pressure point of the fingers on the surrounding flat surface and makes it easy to disassemble and assemble the pushing device.

[0062] In this embodiment, a rotating component and a transmission component are provided, and the multiple components are connected in a nested manner to achieve a split structure between the pushing devices. When the rotating component is pressed, the rotating component separates from the transmission component under the action of the elastic component (a spring in this embodiment) provided between the first rotating rod and the rotating component, thereby realizing the removal, replacement, and installation of the discharge device.

[0063] In some embodiments, the height of the paste / sauce in the storage tank 102 is equal to or less than the sum of the lengths of the threads on the first rotating rod 1011, the second rotating rod 1017, and the third rotating member 1016.

[0064] In some embodiments, a limiting member is provided at the top of the first rotating rod 1015; and / or, a limiting member is provided at the top of the second rotating rod 1017; and / or, a limiting member is provided at the bottom of the third rotating rod 1016.

[0065] A limiting component is provided at the top of the rotating rod. This limiting component prevents the first and second rotating rods from rotating further when they reach the first ends of the first and second housings, respectively. This is to avoid the housing and rotating rods becoming too loose and affecting the minute amount of sauce output.

[0066] In this embodiment, the pushing device has a separate mating relationship between each stage's housing and rotating rod, and the mating is completed to a final limit position during assembly. Furthermore, the housings can be assembled separately from each other, and the housings can be assembled separately from the rotating rod, ensuring stable transmission while facilitating maintenance or replacement of the pushing device.

[0067] The pushing device in this embodiment does not use steel balls, does not require stringent working conditions (sealed and dust-free environment, regular maintenance and lubrication, etc.), has fewer parts, and is easier to assemble.

[0068] Example 2: This example 2 provides another pushing device in the discharge device, which includes all the components of the pushing device in Example 1 above. In addition, the pushing device in this example also includes: at least one intermediate telescopic mechanism, which includes: a third housing 1013, and a third rotating rod 1016 is threadedly connected to the first end of the third housing 1013.

[0069] In particular, in this embodiment, the thread length of the third housing 1013 is less than the length of the third rotating rod 1016.

[0070] In some embodiments, the third housing 1016 is sleeved between the first housing 1011 and the second housing 1014, and the third rotating rod 1016 is sleeved between the first rotating rod 1015 and the second rotating rod 1017.

[0071] In this embodiment, the inner and outer walls of the third rotating rod are respectively provided with grooves and protrusions, and the third housing is also provided with protrusions or grooves.

[0072] As a third rotating rod fitted between the first and second rotating rods, it engages with the protrusions on the inner wall of the first rotating rod and the grooves in the second rotating rod, enabling the third rotating rod to rotate synchronously with the first and second rotating rods. The third housing, due to the engagement of the protrusions and grooves, will not rotate relative to the first and second housings.

[0073] When a third housing with a sleeve is provided, the working principle of the pushing device in this embodiment 2 is as follows: When the driving device 2 drives the first rotating rod 1015 to rotate, the first rotating rod 1015 drives the third rotating rod 1016 and the second rotating rod 1017 to rotate synchronously. At the same time, the first housing 1011 slides along the axial direction of the first rotating rod 1015, and the third housing 1013 slides along the axial direction of the first housing 1011. The third rotating rod 1017 slides along the axial direction of the first rotating rod 1015. At the same time, the second rotating rod 1017 slides along the axial direction of the third rotating rod 1017, and the second housing 1014 slides along the axial direction of the third housing 1013, so that the pushing rod 1018 at the bottom of the second housing 1014 pushes the extruder 103.

[0074] In particular, the pushing device described in this embodiment can be superimposed with multiple intermediate telescopic mechanisms (multiple third shells can be nested together) according to the volume / height of the sauce in the storage tank. The structure and connection method of its shell and rotating rod are the same as the first shell mentioned above. Only the specifications (diameter) of the third shell to be nested need to be adjusted so that it can be nested into the nested shells.

[0075] In this embodiment, except for the intermediate telescopic mechanism (third housing and third rotating rod) in the pushing device, the rest of the structure is the same as the pushing device in Embodiment 1.

[0076] Example 3: This example 3 proposes a discharge device, including a pushing device 101 as described in Example 1 or Example 2 above, and a storage tank 102.

[0077] The top of the storage hopper 102 is connected to the pushing device 101 (detachable or fixed connection). The pushing device 101 is used to push the paste-like sauce in the storage hopper 102. The top of the pushing device 101 is connected to the driving device 2.

[0078] The storage hopper 102 includes a discharge nozzle at one end away from the pushing device 101, and the discharge nozzle is provided with a sealing film with a slit. Preferably, the slit can be cross-shaped or straight, and the film can be soft silicone that meets food quality requirements, or other soft materials that meet food quality requirements.

[0079] In this embodiment, a sealing membrane is provided at the discharge nozzle of the storage tank, and a slightly deformable extruder is provided inside the storage passage. The extruder and the membrane together form a sealed storage space. The paste-like sauce is only sprayed out from the gaps in the sealing membrane when the extruder is squeezed. When the squeezing stops, the paste-like sauce will not flow out from the gaps.

[0080] The working principle of this discharge device can be referred to in Embodiment 1 or 2 above, and will not be repeated here.

[0081] In this embodiment, the discharge device is equipped with multiple coaxially nested multi-stage telescopic mechanisms and a storage tank and extruder that cooperate with them. Based on the threaded transmission between the multi-stage telescopic mechanisms, the length of the pushing device extends step by step. The pushing rod at the bottom of the second housing of the last telescopic mechanism pushes the extruder to move in the storage tank. The first cavity and the second cavity formed by the extruder are in a squeezing state, which makes the extruder form a momentary rapid movement state. The paste-like sauce in this squeezing state is rapidly sprayed out from the discharge nozzle.

[0082] In some embodiments, the storage tank 102 is cylindrical, and correspondingly, the housing in the multi-stage telescopic mechanism is also cylindrical.

[0083] Example 4: This example 4 provides an intelligent sauce machine, including: a machine frame and a discharging device. The structure of the discharging device in this example is the same as that in Example 3.

[0084] The machine frame includes: at least two discharge devices 1 arranged side by side along the width direction; a drive device 2 is rotatably connected to the top of each discharge device 1; a receiving tray 4 is provided below the discharge nozzle of each discharge device 1; and a rinsing device 3 is provided on one side of each discharge device 1. (See also...) Figure 5 .

[0085] The flushing device 3 includes: a liquid storage chamber 301, a power mechanism connected to the liquid storage chamber 301, and a spray nozzle 304 connected to the power mechanism.

[0086] The rinsing device in this application is provided because the concentrated sauce needs to be fully diluted (by water or other liquids), and to ensure that the paste-like sauce does not stick to the receiving tray 4, water is sprayed into the receiving tray 4 before the sauce falls into it. The diluted sauce then flows into the receiving box. Furthermore, this application offers various sauces with different flavors (multiple dispensing devices), thus requiring a rinsing device to dilute the mixed sauces.

[0087] In some embodiments, the receiving tray 4 includes an inclined surface 303, which is inclined and the angle between the inclined surface and the horizontal plane is 2°-5° when the sauce machine is placed on a plane parallel to the horizontal plane.

[0088] Preferably, the spray nozzle 304 is disposed on the higher side of the inclined surface of the receiving tray 4, with the spray nozzle 304 facing the inclined surface of the receiving tray 4, and a receiving box 9 is disposed on the lower side of the inclined surface of the receiving tray 4.

[0089] Preferably, the position of the intersection of the nozzle's axis and the inclined surface does not exceed the position of the discharge nozzle of the leftmost discharge device. That is, the straight-line distance between the intersection of the nozzle's axis and the inclined surface and the water tank is less than the straight-line distance between the discharge nozzle of the discharge device closest to the water tank and the water tank. Furthermore, the angle between the nozzle's axis and the inclined surface is 5°-10°, and the spray direction of the liquid is substantially along the nozzle's axis. See [reference needed]. Figure 11 .

[0090] The machine frame is equipped with a mounting bracket 6. The bottom of the mounting bracket 6 has a second limiting groove for mounting the discharge device 1. The discharge nozzle of the discharge device 1 extends out from the bottom of the second limiting groove and faces the receiving tray 4. The top of the mounting bracket 6 has a mounting groove for mounting the drive device 2. Each mounting groove has a limiting part below it for cooperating with the second limiting groove to limit the position of the storage bin. (See also...) Figure 6 By setting the limiting groove and limiting part, the stability of the detachable discharge device is ensured, thereby ensuring the stability of the entire discharge process and avoiding the discharge device from shifting due to collisions or other reasons, which would affect the discharge.

[0091] A cooling mechanism 5 is provided on one side of the mounting frame 6. A conduction plate 7 connected to the cooling mechanism 5 is disposed inside the mounting frame 6. The conduction plate 7 is provided with a slot that contacts and clamps and limits the outer surface of the storage bin. See [reference needed] Figure 4 Preferably, the slot has a semi-circular cross-section, perfectly fitting the cylindrical storage bin. Preferably, the length of the slot is almost equal to the length of the storage bin. This ensures the stability of the discharging device and avoids affecting the discharging process.

[0092] The working principle of this sauce machine is as follows: When the multi-stage telescopic mechanism in the driving device 2 drives the pushing device 101 to extend, the pushing rod drives the extruder to move axially along the storage tank, causing the sauce contained in the storage tank 102 to be sprayed from the discharge nozzle into the receiving tray below. Under the action of the power mechanism, the rinsing device 3 delivers the rinsing liquid in the storage chamber 301 to the spray nozzle 304 and sprays the rinsing liquid into the receiving tray 4 to rinse and mix the sauce on the receiving tray 4. The mixture after mixing with the rinsing liquid flows into the receiving box 9 along the inclined surface of the receiving tray 4.

[0093] In some embodiments, a weighing device 8 is also provided below the receiving tray 4. The weighing device 8 includes a weighing box for placing food and a weighing pan 801 for weighing the weighing box. The area below the receiving tray 4 inside the machine frame forms a weighing chamber for setting the weighing device 8.

[0094] Specifically, the weighing pan 801 is disposed on the housing between the two arc-shaped slide rails 802 on both sides. The arc-shaped slide rails include: a first arc-shaped slide rail connected to the weighing chamber, and a second arc-shaped slide rail that slides within the first arc-shaped slide rail. The second arc-shaped slide rail moves within the first arc-shaped slide rail via a sliding member. See [reference needed]. Figure 7 .

[0095] In this embodiment, the weighing pan is set up to facilitate the weighing of the actual items in the symmetrical ingredient box. When the user knows the weight of the food and the types of ingredients, he / she can directly find the amount of the required sauce according to the pre-stored or downloaded ingredient list (the ingredient list includes the names of various dishes, the types and quantities of the required ingredients, and the types and quantities of the required sauces). Thus, the output of each sauce can be controlled by the rotation process of each drive device to achieve the precise output of concentrated sauce in this application.

[0096] In some embodiments, a sterilization element 10 is provided between the receiving tray 4 and the discharge nozzle of the discharge device. Preferably, the sterilization element 10 is an ultraviolet lamp.

[0097] In some embodiments, the housing is provided with a plurality of reinforcing members.

[0098] In some embodiments, the power mechanism includes a liquid pump 302, which is connected to the nozzle 304 and the liquid storage chamber 301 via connecting pipes.

[0099] In some embodiments, the length and number of the slots are the same as those of the storage bin 102.

[0100] In some embodiments, the sauce maker also includes a housing, on which a magnetic element 11 is provided. The magnetic element can be used to magnetically attach a mobile phone, so that when the user needs to use the mobile phone to find sauce recipes or video tutorials, there is no need to set up a separate mobile phone stand or hold the mobile phone.

[0101] In some embodiments, the conductive plate 7 is provided with a slot that contacts the outer surface of the storage tank 102 and clamps and limits its movement.

[0102] Existing sauce dispensers are typically designed for sauces that can be directly added to food and contain chemical preservatives for easy preservation. They require users to manually mix multiple sauces themselves. They are not designed for concentrated sauces that contain biological preservatives, have a relatively short shelf life, and require dilution and mixing. Furthermore, existing sauce dispensers usually use peristaltic pumps for precise sauce dispensing. Due to their high manufacturing cost, they are typically designed for long-term use. This not only increases the user's maintenance costs but also poses a risk of contaminating new sauces due to inadequate cleaning during repeated use. This application targets concentrated sauces with short shelf lives. The amount of sauce pre-filled in each storage tank is sufficient to meet a family's daily needs for a long period (e.g., several months). Therefore, this application proposes a new sauce dispenser that achieves refrigeration by setting up a refrigeration mechanism and using a conduction plate. It also achieves sealed refrigeration by using a sealing film at the extrusion part and the dispensing nozzle of the storage tank. During both the extrusion and dispensing processes, almost no air or other foreign matter enters the sealed dispensing space, thus enabling the concentrated sauce to be stored for a longer period of time. (Furthermore, a sterilization part is set up to sterilize the dispensing nozzle, which further assists in achieving long-term storage without spoilage.) Through the internal structural design of the pushing device and the synergistic limiting effect with other components, stable dispensing can be achieved throughout the dispensing process of the storage tank. At the same time, it can also dilute and mix multiple sauces output from multiple dispensing devices to obtain a mixed liquid, which is finally output into a receiving box. This allows users to directly pour the mixed liquid from the receiving box into food for use, and then manually mix the sauces together. Furthermore, in order to save costs and reduce the complexity of the process, the dispensing device is made of plastic and is designed to be detachable as a whole, so that the entire dispensing device can be replaced after one use. This not only reduces costs but also avoids the risk of contaminating new sauces due to inadequate cleaning.

[0103] As the sauce in this application is a concentrated sauce, the control of the discharge volume (micro-volume) needs to be extremely precise. Furthermore, it is crucial to ensure a certain degree of accuracy in the micro-discharge even when the remaining sauce in the storage tank is low; that is, the entire discharging process needs to guarantee a stable micro-discharge. Therefore, the discharging device of this application uses a storage tank with a sealing membrane at the discharge end. A slightly deformable extruder is placed inside the storage tank. The extruder and membrane form a sealed storage space. Multiple coaxially nested multi-stage telescopic mechanisms drive the extruder to move while undergoing slight deformation, thereby achieving micro-discharge. For example, based on the threaded transmission between the multi-stage telescopic mechanisms, the length of the pushing device extends progressively, and the pushing rod at the bottom of the third housing of the final telescopic mechanism pushes the extruder to move within the storage tank. The extruder forces the paste-like sauce into a tiny volume (the exact output can be determined by controlling the motor's rotation angle or number of revolutions to extend the multi-stage telescopic mechanism, thus achieving quantitative dispensing) from the opening of the film at the discharge nozzle. When the extruder slightly deforms and returns to its original position, the resulting negative pressure closes the film opening again, preventing sauce residue or dripping from the nozzle and further ensuring precise micro-dispensing. Furthermore, the multi-stage telescopic mechanism facilitates the miniaturization of the sauce machine and maximizes the use of internal space.

[0104] The final telescopic mechanism of the discharging device in this application, namely the second housing, adopts an assembly method of internal full thread and rotating rod, and a limiting groove is set on the extruder to limit the push rod of the second housing, thereby ensuring the stability between the housing and the extruder, thus ensuring the stability of micro-discharge, and preventing the inability to accurately discharge micro-volumes due to the flexibility of the connection between the multi-stage telescopic mechanisms, or when the remaining amount of sauce in the storage tank is small, giving each component a large space for movement. At the same time, the first outer wall and the second protrusion of the extruder form a first cavity, and the middle part of the second protrusion is recessed to form a second cavity (in the initial state, that is, before the start of discharging, the two cavities are not filled with sauce, so there is a certain amount of gas in the two cavities). When the extruder is squeezed, due to the action of the first protrusion and the reinforcing rib, the second protrusion can undergo slight deformation, thereby discharging micro-volumes under the action of the two cavities, and the squeezed sauce is retracted due to the cooperation of the second cavity and the first cavity, preventing residual sauce or excess dripping from the nozzle. The discharge device of this application, based on manufacturing cost considerations, not only allows for one-time replacement of the discharge device, but also meets the requirement of precise discharge.

[0105] The machine frame of this application is equipped with a rinsing device and a receiving tray. The receiving tray, located below the dispensing device, includes an inclined surface. A spray nozzle connected to the rinsing device dilutes and mixes various sauces falling into the receiving tray while simultaneously rinsing the tray (for example, rinsing liquid is sprayed before the sauce is sprayed and continues to be sprayed throughout the dispensing process, diluting the sauces and reducing the adhesion between the sauces and the receiving tray), thus eliminating the need for separate cleaning of the receiving tray. Meanwhile, the diluted sauces flow into a receiving box on the lower side of the receiving tray. In this application, to ensure both the ability to mix and dilute various sauces and a certain flushing capacity, the acute angle between the nozzle axis and the 2°-5° inclined plane is set to 5°-10°. Furthermore, the intersection of the nozzle axis and the inclined plane is located a distance to the left of the nearest landing point of the sauce on the inclined plane (i.e., the intersection of the sauce's landing direction and the inclined plane) among the multiple dispensing devices. (That is, the position of the intersection of the nozzle axis and the inclined plane does not exceed the position of the dispensing nozzle of the leftmost dispensing device; and the straight-line distance between the intersection of the nozzle axis and the inclined plane and the water tank is less than the straight-line distance between the dispensing nozzle of the dispensing device closest to the water tank and the water tank.) The location is chosen such that the intersection point and the landing points of various sauces on the inclined surface are on the same straight line. Through this specific structural design and their coordinated operation, the kinetic energy of the liquid is mainly decomposed along the inclined surface of the receiving tray, generating a strong shear force. This not only guides the flow well but also forms a liquid "film" on the inclined surface, effectively "scraping" away the sauces. In addition, the liquid flows "along" the surface rather than "smashing" or splashing onto it, thus reducing liquid splashing. Furthermore, since the intersection point is located to the left of the nearest landing point (not overlapping), the dilution and mixing process begins before the sauces contact the tray surface, achieving pre-mixing and dilution, greatly improving mixing efficiency and uniformity, and preventing the sauces from directly adhering to the tray surface. If the angle between the nozzle and the inclined surface is too large, for example, if the liquid is set vertically and impacts the inclined surface vertically, the kinetic energy will mainly be converted into splashing, resulting in low mixing efficiency, wasted resources, and safety hazards.

[0106] The frame of this application is also equipped with a refrigeration mechanism. The conduction plate connected to the refrigeration mechanism is in contact with the storage tank containing the concentrated sauce, so that the storage environment of the sauce is at a low temperature, ensuring that the sauce can be stored for a long time without spoiling.

[0107] Example 5: This example provides a sauce machine. The structure of this sauce machine is the same as that of the intelligent sauce machine in Example 4. The difference is that the pushing device of this sauce machine may not be the above-mentioned pushing device as a disposable consumable, but other structures may be used to achieve quantitative dispensing of sauce.

[0108] In this embodiment, the telescopic mechanism in the sauce-pushing device can be another multi-stage nested telescopic mechanism, wherein the primary telescopic mechanism is connected to the output shaft of the drive device 2; and the final telescopic mechanism has an extruder for pushing the sauce at the end near the discharge nozzle. Alternatively, the pushing device can be a hydraulic cylinder, a pneumatic cylinder, or a peristaltic pump.

[0109] In some embodiments, the sterilization element 10 is an ultraviolet lamp.

[0110] In some embodiments, the receiving box 9 and the receiving tray 4 are drawer-type structures with handles.

[0111] In some embodiments, the liquid storage chamber 301 is a drawer-type structure within the frame.
