Description

Technical Field

[0001] This application relates to the field of material supply, and in particular to a material supply structure for a smoothie machine. Background Technology

[0002] In the field of liquid feeding and discharging technology, especially in the automatic feeding and discharging of closed liquid containers, its development is crucial for many devices that use liquid raw materials in production or processing. For example, in equipment such as smoothie machines, the efficiency and safety of feeding and discharging directly affect the quality of the product and the user experience. With the increasing market demand for smoothies and other cold drinks, the performance requirements for smoothie machines are also rising, making efficient and safe liquid supply and replacement devices a key direction for industry development.

[0003] In traditional shaved ice machines, the following methods are typically used to address the issues of liquid supply and discharge. For the liquid storage device, to ensure a continuous supply of liquid to the machine, after adding beverage liquid to the storage device, it is usually reversed and inserted into the machine. The discharge port of the storage device typically uses a steel ball sealing structure, relying on gravity for sealing. Regarding the machine's discharge, a liquid supply tray is located below the drum evaporator. During normal operation, the liquid is stored and supplied through this tray, and after the machine stops working, the tray is usually full of beverage liquid.

[0004] However, existing technology has significant drawbacks. During the process of changing the liquid storage device from upright to inverted, a small amount of beverage liquid may leak due to the liquid flow and the inertia of the steel ball's movement, affecting the user experience. Furthermore, if the liquid tray is removed for cleaning after the machine stops working, the beverage liquid inside the tray may accidentally spill into the machine, making cleaning very tedious, time-consuming, and laborious, thus impacting the user experience. Utility Model Content

[0005] The purpose of this application is to provide a feeding structure for a smoothie machine.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a feeding structure for a smoothie machine, comprising a feeding tray and a storage tank; a top column is provided on the feeding tray; the storage tank is provided with a liquid outlet, and an installation component is fixed inside the storage tank; a feeding rod is provided on the installation component, and the feeding rod is slidably inserted through the installation component along the axial direction; a first sealing element is provided on the feeding rod, which can seal and cooperate with the edge of the liquid outlet to close the liquid outlet; a first reset element is provided between the first sealing element and the installation component; when the storage tank is placed above the feeding tray, the top column abuts against the feeding rod, pushing the first sealing element and the installation component to squeeze the first reset element to open the liquid outlet; when the storage tank is separated from the feeding tray, the top column disengages from the feeding rod, and the first reset element releases its elastic force to push the first sealing element to reset and re-seal and cooperate with the edge of the liquid outlet to close the liquid outlet.

[0007] By adopting the above technical solution, efficient cooperation and sealing control between the liquid storage tank and the feeding tray are achieved: when the liquid storage tank is placed above the feeding tray, the top column abuts against the feeding rod and pushes the first sealing element to squeeze the first reset element, so that the liquid outlet of the liquid storage tank opens to supply liquid to the feeding tray, ensuring the automatic start of the feeding process; when the liquid storage tank is separated from the feeding tray, the first reset element releases its elastic force to push the first sealing element to reset, and re-seals with the edge of the liquid outlet to close the liquid outlet, effectively avoiding leakage problems caused by liquid flow or component inertia during the handling of the liquid storage tank, improving the cleanliness and convenience of the use process, and at the same time, the structural design realizes the automatic switching of liquid supply and sealing, reducing the cumbersome manual operation and improving the user experience.

[0008] Optionally, a limiting edge is provided at the liquid outlet. When the liquid level in the feeding tray rises to the limiting edge, the liquid surface can seal the liquid outlet to prevent external air from entering the liquid storage tank.

[0009] By adopting the above technical solution, when the liquid level in the feeding tray rises to the limit edge, the liquid surface can seal the outlet to prevent external air from entering the storage tank. This design utilizes the principle of liquid level difference and air pressure balance to realize the automatic start and stop of liquid supply. It can accurately control the amount of liquid in the feeding tray without additional control components, avoiding the problem of liquid overflow caused by excessive liquid supply. This not only ensures the stability and continuity of the feeding process, but also reduces liquid waste, further improving the automation level and reliability of the device.

[0010] Optionally, the first reset element is a spring, and the first reset element is fitted onto the feed rod.

[0011] By adopting the above technical solution, the first reset component is set as a spring and fitted onto the feeding rod. This not only utilizes the stable elastic restoring force of the spring to achieve precise reset of the first sealing component, ensuring reliable sealing of the outlet when the liquid storage tank is separated from the feeding tray, but also allows the spring force to be stably transmitted along the axial direction of the feeding rod through the fitted structure, avoiding offset or jamming during the reset process. At the same time, it simplifies the overall structural layout, makes the component connections more compact, and makes installation and maintenance more convenient, effectively ensuring the smoothness and stability of the feeding and sealing switching process.

[0012] Optionally, the liquid storage tank is provided with a filter grid inside, and the filter grid is located between the feed rod and the liquid storage tank cavity.

[0013] By adopting the above technical solution, a filter grid is installed inside the liquid storage tank and between the feeding rod and the liquid storage tank cavity. This effectively intercepts large solid particles in the liquid, preventing them from entering the mating area between the feeding rod and the liquid outlet. This avoids the failure of the first sealing element due to particle blockage. At the same time, it also prevents large particles from entering the feeding tray to participate in ice making, ensuring the smooth texture of the shaved ice. This reduces equipment failures caused by impurities and improves the operational stability of the device and the quality of the product.

[0014] Optionally, the feeding tray is provided with a drain port, and the feeding tray is provided with a drain assembly corresponding to the drain port.

[0015] By adopting the above technical solution, a drain port is set on the feeding tray and a corresponding drain component is configured, so that the remaining liquid in the feeding tray can be discharged in a concentrated manner through the drain port. This avoids the problem of liquid accidentally spilling into the machine body when disassembling the feeding tray for cleaning in the traditional structure, which greatly simplifies the cleaning process and reduces the amount of cleaning work. At the same time, it is convenient to drain the residual liquid when changing different liquid raw materials, prevent the mixing of different flavor liquids, improve the convenience and hygiene of the equipment, and expand the applicable scenarios of the device.

[0016] Optionally, the drain assembly includes a drain body that is movable relative to the feed tray; the feed tray has a drain button connected to a drive block that is slidable relative to the drain body; the drain body has a protruding mounting block with a guide slope adapted to the drive block, and the drive block forms a wedge-shaped fit with the mounting block through the guide slope; the drain body has a draining hydraulic block corresponding to the drain port, and the draining hydraulic block has a second sealing element adapted to seal the drain port. A second reset member is elastically supported between the feed tray and the feed plate. When the drain button is pressed, causing the drive block to slide relative to the drain body, the drive block pushes the mounting block through the guide slope, causing the drain body to overcome the elastic force of the second reset member and move away from the drain port, so that the second seal is disengaged from the drain port to open the drain port. When the drain button is released, after the drive block is reset, the second reset member drives the drain body to move closer to the drain port through elastic force until the second seal fits against the drain port to achieve a seal.

[0017] By adopting the above technical solution, the drainage assembly achieves precise control of the drainage port through a wedge-shaped fit and elastic reset structure: when the drainage button is pressed, the drive block pushes the mounting block through the guide slope, causing the drainage body to move against the elastic force of the second reset element and disengage the second seal from the drainage port, quickly opening the drainage port; after releasing the button, the elastic force of the second reset element drives the drainage body to reset, causing the second seal to tightly fit the drainage port to complete the seal. This mechanical linkage structure is not only easy to operate, enabling reliable switching between drainage and sealing through a simple pressing action, but also avoids the dripping problem that may occur in traditional drainage structures. At the same time, the wedge-shaped fit design ensures stable transmission of driving force, reduces component wear, improves the service life and working stability of the drainage assembly, and further optimizes the user's operating experience.

[0018] Optionally, the first seal and / or the second seal may be made of a food-grade elastic material.

[0019] By adopting the above technical solution, the first and / or second sealing components are made of food-grade elastic material. This ensures a tight fit between the sealing surfaces through the elastic deformation of the material, improving sealing reliability and preventing liquid leakage. It also meets the hygiene and safety requirements of food contact scenarios, preventing the material from reacting chemically with the liquid or releasing harmful substances. At the same time, the food-grade elastic material has good temperature resistance and corrosion resistance, which can adapt to temperature changes and liquid erosion during the use of the smoothie machine, extending the service life of the sealing components. This approach balances sealing performance, safety, and durability.

[0020] Optionally, the feeding tray is provided with an overflow edge, the feeding tray is provided with an overflow groove, and the overflow groove is provided with an overflow port.

[0021] By adopting the above technical solution, an overflow edge, an overflow trough, and an overflow port are set on the feeding tray. The overflow edge is a structural edge that is lower than the other edges of the feeding tray. When the liquid in the feeding tray exceeds the overflow edge, the liquid can flow into the overflow trough along the overflow edge and be discharged through the overflow port. This effectively prevents the liquid from overflowing from the other outer edges of the feeding tray and polluting the internal or external environment of the machine, reducing the cleaning burden. At the same time, this structured overflow design ensures the directional discharge of excess liquid, improves the safety and cleanliness during equipment use, and further optimizes the user experience.

[0022] In summary, this application has at least the following beneficial effect:

[0023] 1. Achieves efficient coordination and sealing control between the liquid storage tank and the feeding tray: When the liquid storage tank is placed above the feeding tray, the top column abuts against the feeding rod and pushes the first sealing element to squeeze the first reset element, opening the liquid outlet of the liquid storage tank to supply liquid to the feeding tray, ensuring the automatic start of the feeding process; when the liquid storage tank is separated from the feeding tray, the first reset element releases its elastic force to push the first sealing element to reset, re-sealing with the edge of the liquid outlet to close the liquid outlet, effectively avoiding leakage problems caused by liquid flow or component inertia during the handling of the liquid storage tank, improving the cleanliness and convenience of use, and at the same time, the structural design realizes the automatic switching of liquid supply and sealing, reducing the cumbersome manual operation and improving the user experience.

[0024] 2. When the liquid level in the feeding tray rises to the limit edge, the liquid surface can seal the outlet to prevent external air from entering the storage tank. This design utilizes the principle of liquid level difference and air pressure balance to achieve automatic start and stop of liquid supply. It can accurately control the amount of liquid in the feeding tray without additional control components, avoiding liquid overflow caused by excessive liquid supply. This not only ensures the stability and continuity of the feeding process, but also reduces liquid waste, further improving the automation level and reliability of the device.

[0025] 3. The drainage assembly achieves precise control of the drainage port through a wedge-shaped fit and elastic reset structure: When the drainage button is pressed, the drive block pushes the mounting block through the guide ramp, causing the drainage body to move against the elastic force of the second reset element and disengage the second seal from the drainage port, quickly opening the drainage port; after releasing the button, the elastic force of the second reset element drives the drainage body to reset, causing the second seal to tightly fit the drainage port to complete the seal. This mechanical linkage structure is not only easy to operate, enabling reliable switching between drainage and sealing through a simple pressing action, but also avoids the dripping problem that may occur in traditional drainage structures. At the same time, the wedge-shaped fit design ensures stable transmission of driving force, reduces component wear, improves the service life and working stability of the drainage assembly, and further optimizes the user's operating experience.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] In this embodiment, refer to Figures 1-5This application provides a feeding structure for a smoothie machine, including a feeding tray 1 and a liquid storage tank 2. The liquid storage tank 2 is placed above the feeding tray 1, and the two work together to achieve liquid supply and discharge, achieving beneficial effects such as automatic, continuous, and stable liquid supply, prevention of liquid leakage, convenient cleaning and management, and support for rapid changes in ice-making liquid. These beneficial effects are due to the special structural design between the feeding tray 1 and the liquid storage tank 2, which makes liquid supply and discharge more efficient, safe, and convenient.

[0035] Specifically, the feeding tray 1 is equipped with a top column 3. The top column 3 is usually a columnar structure, and its material can be stainless steel or other metal materials, which have a certain strength and corrosion resistance. The top column 3 can be cylindrical or square, etc. It is installed on the feeding tray 1, and can be an integral structure with the feeding tray 1, or it can be fixed by welding, threaded connection, etc. The function of the top column 3 is to abut against the feeding rod 6 inside the liquid storage tank 2 when the liquid storage tank 2 is placed above the feeding tray 1, thus pushing the feeding rod 6 to move.

[0036] The liquid storage tank 2 is equipped with a liquid outlet 4, and a mounting component 5 is fixed inside the liquid storage tank 2. The liquid outlet 4 is the channel for the liquid to flow out of the liquid storage tank 2, and its shape is generally circular. The mounting component 5 can be a plate-like structure with mounting holes, and its material can be plastic or metal. It is fixed inside the liquid storage tank 2 by means of threads, clips, etc. The mounting component 5 is equipped with a feeding rod 6, which is slidably inserted into the mounting component 5 along the axial direction. The feeding rod 6 is generally a rod-like structure, and its material can be stainless steel or plastic. Its surface should be smooth to reduce friction with the mounting component 5. The fit between the feeding rod 6 and the mounting component 5 can be a clearance fit, allowing the feeding rod 6 to slide smoothly within the mounting holes of the mounting component 5.

[0037] The feeding rod 6 is equipped with a first sealing element 7, which can seal the edge of the liquid outlet 4 to close it. The first sealing element 7 can be a food-grade elastic sealing ring, such as silicone, which is safe, non-toxic, and meets food hygiene requirements. It is fixed to the feeding rod 6 by sleeve or adhesive. When the first sealing element 7 is tightly fitted to the edge of the liquid outlet 4, it can effectively prevent liquid leakage. A first reset element 8 is provided between the first sealing element 7 and the mounting part 5. The first reset element 8 is a spring, which is fitted onto the feeding rod 6. The spring stores elastic potential energy when compressed and releases elastic force when the external force is removed. Its material can be stainless steel, and the elastic coefficient can be adapted as needed to ensure sufficient elastic force for the reset of the first sealing element 7.

[0038] When the storage tank 2 is placed above the feeding tray 1, the top column 3 abuts against the feeding rod 6, pushing the first sealing element 7 and the mounting element 5 to squeeze the first reset element 8, thus opening the outlet 4. At this time, the liquid in the storage tank 2 can flow into the feeding tray 1 through the outlet 4. When the storage tank 2 separates from the feeding tray 1, the top column 3 disengages from the feeding rod 6, and the first reset element 8 releases its elastic force to push the first sealing element 7 to reset and re-seal the edge of the outlet 4, thus closing the outlet 4 and preventing liquid leakage. The combination logic of the feeding rod 6, the first sealing element 7, the mounting element 5, and the first reset element 8 is as follows: the top column 3 pushes the feeding rod 6 to move, the feeding rod 6 drives the first sealing element 7 to move, squeezing the first reset element 8, causing the first sealing element 7 to separate from the outlet 4, allowing the liquid to flow out; when the top column 3 disengages from the feeding rod 6, the elastic force of the first reset element 8 resets the first sealing element 7, closing the outlet 4. This combination ensures that the outlet 4 can be accurately opened and closed when the storage tank 2 is placed and separated, preventing liquid leakage.

[0039] Specifically, a limiting edge 9 is provided at the liquid outlet 4. The limiting edge 9 can be a raised structure surrounding the edge of the liquid outlet 4, and its material can be the same as that of the storage tank 2. When the liquid level in the supply tray 1 rises to the limiting edge 9, the liquid surface can seal the liquid outlet 4 to prevent external air from entering the storage tank 2. This is because when the liquid surface seals the liquid outlet 4, the liquid in the storage tank 2 cannot continue to flow out, thus achieving self-stopping of liquid supply based on the liquid level difference and avoiding overflow. The setting of the limiting edge 9 makes the liquid supply process safer and prevents liquid overflow from causing waste and pollution.

[0040] Specifically, the liquid storage tank 2 is equipped with a filter grid 10, located between the feeding rod 6 and the cavity of the liquid storage tank 2. The filter grid 10 is integrally injection molded, forming a mesh structure through mold casting. The mesh size is designed according to actual needs to effectively block large particles. The filter grid 10 is fixed to the inside of the liquid storage tank 2 by snap-fit ​​or welding. When the user adds liquid containing solids to the liquid storage tank 2, the filter grid 10 can effectively intercept large particles, preventing them from getting stuck at the seal and causing seal failure, while also preventing large particles from participating in ice making and affecting the taste. The filter grid 10 improves the quality and taste of ice making and ensures the reliability and stability of the feeding structure.

[0041] Specifically, the feeding tray 1 is provided with a drain port 11, and a drain assembly 12 is provided at the position corresponding to the drain port 11. The drain port 11 is the channel for liquid to be discharged from the feeding tray 1. The drain assembly 12 is used to control the opening and closing of the drain port 11 to realize the discharge of liquid.

[0042] The drain assembly 12 includes a drain body 121, which is movable relative to the feed tray 1. The drain body 121 can be a block structure made of plastic or metal. The feed tray 1 has a drain button 122 connected to a drive block 123, which is slidable relative to the drain body 121. The drain button 122 is generally a circular or square block structure made of plastic and connected to the drive block 123 via injection molding or other methods. The drive block 123 can be a block structure with an inclined surface, made of the same material as the drain body 121, and slides relative to the drain body 121 via guide rails, grooves, or other means. The drain body 121 has a protruding mounting block 124 with a guide inclined surface adapted to the drive block 123, forming a wedge-shaped fit between the drive block 123 and the mounting block 124 via the guide inclined surface. The mounting block 124 and the drain body 121 can be integrally formed. The angle of its guide slope should be designed according to actual needs to ensure that the drive block 123 can smoothly push the mounting block 124.

[0043] A drainage block 125 is provided on the drainage body 121 corresponding to the drainage port 11. The drainage block 125 has a second sealing element 126 that can adapt to seal the drainage port 11. A second reset element 127 provides elastic support between the drainage body 121 and the feeding tray 1. The drainage block 125 is generally a block structure, made of the same material as the drainage body 121, and is fixed to the drainage body 121 by threaded connection, snap-fit, or integral injection molding. The second sealing element 126 is also made of food-grade elastic material, such as silicone, and is fixed to the drainage block 125 by sleeve or adhesive. The second reset element 127 can be a spring, with a material and elastic coefficient similar to the first reset element 8, and provides elastic support by connecting its two ends to the drainage body 121 and the feeding tray 1 respectively.

[0044] When the drain button 122 is pressed, causing the drive block 123 to slide relative to the drain body 121, the drive block 123 pushes the mounting block 124 through the guide ramp, causing the drain body 121 to overcome the elastic force of the second reset member 127 and move away from the drain port 11, so that the second seal 126 disengages from the drain port 11 to open the drain port 11. At this time, the liquid in the feed tray 1 is discharged through the drain port 11 under the action of gravity. When the drain button 122 is released, after the drive block 123 resets, the second reset member 127 drives the drain body 121 to move closer to the drain port 11 through elastic force until the second seal 126 fits against the drain port 11 to achieve a seal. This structural design of the drain assembly 12 makes the draining process more convenient and reliable. The user only needs to press the drain button 122 to discharge the liquid, and the drain port 11 automatically seals after the button is released to prevent liquid leakage.

[0045] Specifically, the feeding tray 1 is provided with an overflow edge 13, an overflow groove 14, and an overflow port 15. The overflow edge 13 is a structural edge at the edge of the feeding tray 1 that is lower than other outer edges, and its material is the same as that of the feeding tray 1. When the liquid in the feeding tray 1 exceeds the overflow edge 13, the liquid can flow along the overflow edge 13 to the overflow groove 14. The overflow groove 14 is a recessed structure on the feeding tray 1 that extends along the overflow edge 13 and is used to collect the overflowing liquid. The overflow port 15 is located in the overflow groove 14 and is the channel for the overflowing liquid to be discharged. The arrangement of the overflow edge 13, the overflow groove 14, and the overflow port 15 further improves the safety of the feeding structure by limiting the overflow path to the range from the overflow edge 13 to the overflow groove 14, preventing liquid leakage from other outer edges of the feeding tray 1 and causing damage to the smoothie machine. When cleaning the feed tray 1, the injected cleaning water can flow naturally along the overflow edge 13 to the corresponding overflow trough 14 during the rinsing process, and then be discharged from the overflow trough 14 through the overflow port 15. This not only prevents the cleaning water from accumulating in the feed tray 1, but also achieves self-cleaning by rinsing the overflow trough 14 itself through the water flow. This structural design is specially adapted to cleaning scenarios, ensuring that sewage is discharged in an orderly manner during the cleaning process, preventing cleaning water from seeping into the machine body and causing damage to components, while simplifying the cleaning operation process and improving the convenience of daily maintenance of the feed tray 1.

[0046] The implementation principle of this embodiment is as follows: The slush machine's feeding structure in this embodiment achieves automatic liquid supply and discharge through the cooperation of the feeding tray 1 and the storage tank 2. During the liquid supply process, automatic liquid supply is achieved by utilizing the liquid level difference. When the liquid level in the feeding tray 1 rises to the limiting edge 9 at the liquid outlet 4, the atmospheric pressure difference blocks external air from entering the storage tank 2, and the supply is automatically stopped by utilizing air pressure balance to avoid overflow. During the removal and placement of the storage tank 2, liquid leakage is prevented by the action of the first sealing element 7 and the first reset element 8. The overflow edge 13, overflow groove 14, and overflow port 15 further enhance safety. These designs improve upon the problems of liquid leakage and cumbersome cleaning in the prior art, improve the performance and user experience of the slush machine, and meet the higher demands of commercial and household ice-making equipment.

[0047] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
