Description

Technical Field

[0001] This utility model relates to the field of snow melting equipment technology, and in particular to a snow melting machine suitable for home use and for making snow melting products. Background Technology

[0002] Existing snow melting machines typically include a base and a material cylinder mounted on the base. The base contains a power unit and a refrigeration unit. Inside the material cylinder is an evaporator and a stirring paddle fitted outside the evaporator. The beverage is placed in the material cylinder, cooled by the evaporator, and stirred by the stirring paddle to achieve uniform processing.

[0003] In existing slush machines, liquid beverages are first fed into the feed tank through the inlet. After being cooled by the evaporator, the beverage is discharged from the outlet. During processing, the outlet must remain sealed to prevent leakage. After processing, the user must guide the processed beverage out of the outlet. However, because the beverage undergoes a phase change during cooling within the slush machine, transforming from a liquid to a flowable ice crystal structure, the sealing requirements for the feed tank differ before and after processing.

[0004] Existing slush machines typically have a dispensing nozzle assembly at the outlet of the material cylinder for controlling the opening or closing of the outlet. This dispensing nozzle assembly is hinged to the material cylinder and includes a handle for user operation and a sealing part for closing the outlet. The user operates the handle to control the sealing part to open or close the outlet. During operation, the handle and the material cylinder abut against each other to form a pivot point for rotation, and the handle both rotates and moves relative to the material cylinder. Furthermore, due to changes in shape during processing, existing slush machines still have the following shortcomings: when the beverage is liquid, sufficient pre-tightening force is required between the sealing part and the outlet to ensure a seal; after processing, the user usually operates the dispensing nozzle assembly multiple times to dispense ingredients as needed, requiring a smaller squeezing force for user convenience. This contradiction means that existing dispensing nozzle assemblies cannot simultaneously satisfy both optional sealing and convenient user operation. Furthermore, the existing product's discharge nozzle assembly acts directly on the material cylinder, requiring high strength from the cylinder's sidewalls. The material cylinder must withstand the combined effects of various forces, including the force from the internal food ingredients, the impact of temperature changes during processing, the strength requirements of the discharge nozzle assembly installation, and the force exerted during operation. This significantly reduces the normal service life of the material cylinder, thereby affecting the long-term use of the snow melting machine. Utility Model Content

[0005] In view of the technical defects and deficiencies of the prior art, the purpose of this utility model is to provide a snow melting machine that is easy to operate, so as to solve the technical problems of poor sealing structure reliability, complicated operation, laborious and inconvenient operation, and insufficient strength of the material cylinder in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides a snow melting machine that is easy to operate, including a base, a refrigeration component and a power component disposed within the base, and a processing module disposed on the upper part of the base. The processing module includes a material cylinder and an evaporator and a stirring paddle disposed within the material cylinder. The stirring paddle is sleeved around the evaporator. The refrigeration component includes a compressor and a condenser in fluid communication with the evaporator. The power component passes through the evaporator to drive the stirring paddle. The bottom of the side wall of the material cylinder is provided with a discharge port and a discharge component for controlling the opening and closing of the discharge port. The material cylinder is provided with a rotating base for mounting the discharge component. The discharge component includes a sealing rod hinged to the material cylinder, a sealing element connected to the sealing rod and capable of closing the discharge port, and a handle hinged to the sealing rod to push the sealing rod. The handle pushes the sealing rod to switch between a closed position (closing the discharge port) and a discharge position (opening the discharge port). The side wall of the material cylinder is also provided with a support seat that abuts against the handle.

[0007] In this application, to ensure reliable sealing while making operation easier for the user, the discharge assembly includes a sealing rod with a seal and a handle. The sealing rod is hinged to the material cylinder and drives the seal to close and open the discharge port. When the discharge port needs to be sealed, the sealing rod drives the seal to close the discharge port. The leverage effect of the seal, sealing rod, and handle ensures a stable and reliable seal. When the discharge port needs to be opened, the handle acts as a first-level lever, and the handle drives the sealing rod to act as a second-level lever, greatly reducing the force required to operate the handle and significantly improving the user experience and satisfaction. Furthermore, in this application, the handle does not directly limit the fulcrum position of the lever during pushing; that is, the handle slides relative to the material cylinder, so that the support point between the handle and the material cylinder is in a changing state. This reduces the length of the handle while reducing the operating force. Furthermore, the sliding support point prevents the material cylinder from being subjected to excessively high force at a single point, avoiding excessive compression, deformation, or even breakage. Furthermore, the side wall of the material cylinder is also provided with a support seat that abuts against the handle. The support seat bears the force of the handle and distributes the force of the handle to multiple areas of the material cylinder. This effectively avoids stress concentration, alleviates the force on the material cylinder, extends the service life of the material cylinder, and ultimately ensures the reliable use of the snow melting machine.

[0008] As an optional solution, the handle includes a gripping portion and a supporting portion respectively disposed on both sides of the hinge center of the handle, the supporting portion abutting against the supporting base, and the supporting base having a boss protruding toward the supporting portion.

[0009] The handle is further provided with a gripping part and a supporting part, which are located on both sides of the hinge center. It should be noted that since the handle needs to be hinged to the sealing rod to achieve mutual rotation, the handle has a hinge center that mates with the sealing rod. However, since the sealing rod needs to be hinged to both the handle and the material cylinder, it has two different hinge centers. The gripping part allows the user to use the dispensing assembly. The supporting part abuts against the support seat, and the support seat also has a boss protruding towards the supporting part. Thus, when the user operates the gripping part at one end, the support seat at the other end can directly act on the boss, rather than directly on the side wall of the material cylinder, thereby ensuring the structural stability and reliability of the material cylinder and preventing damage. The gripping part and supporting part, located on both sides of the hinge center, further amplify the lever effect of the handle, allowing operation of the dispensing assembly with less force while simultaneously ensuring reliable sealing.

[0010] As an optional solution, the handle also includes a fitting portion adjacent to the hinge center and in contact with the side wall of the material cylinder. The distance from the end of the support portion to the hinge center is greater than the distance from the fitting portion to the hinge center. By operating the grip portion, the end of the support portion abuts against the boss to drive the hinge center away from the side wall of the material cylinder and push the sealing rod from the closed position to the discharge position.

[0011] The fitting part is further provided, and this fitting part is closer to the hinge center than the gripping part and the support part. In this way, in the non-operating state, that is, when the discharge assembly needs to be kept sealed, the fitting part is close to the side wall of the material cylinder, so that the hinge center of the handle is also close to the side wall of the material cylinder. At this time, the sealing rod can drive the sealing element to be stably and reliably kept in the closed position of closing the discharge port. When the user pushes the gripping part, the support part abuts against the boss, so that the sealing rod is disengaged from the discharge port and the discharge port is opened. At this time, the point of action is the matching position of the end of the support point and the boss. By changing the position of the lever fulcrum, the magnitude of the force is changed. Thus, when sealing is required, the fulcrum is close to the center to ensure a large enough force for sealing, while when operation is required, the fulcrum is far from the center to facilitate user operation, thus achieving both reliable sealing and convenient operation.

[0012] As an optional embodiment, the handle includes a contact surface extending from the end of the support portion toward the grip portion and passing through the contact portion, the contact surface being in contact with the side wall of the material cylinder.

[0013] The design includes a contact surface extending from the end of the support portion to the grip portion, which allows the handle to fit more stably against the side wall of the material cylinder when it is in the contact state, i.e. when the material discharge assembly is in the closed state. This ensures that the handle and the corresponding sealing rod are more stable and reliable, and prevents structural shaking of the material discharge assembly during non-operational processes from affecting the sealing effect.

[0014] As an optional solution, a notch is formed between the fitting portion and the supporting portion to accommodate the boss.

[0015] The fitting part is used to ensure the stability and reliability of the discharge assembly, and the cooperation between the support part and the boss is used to ensure the stability and reliability of the operation of the discharge assembly. Both of them act on the side wall of the material cylinder. In order to better cooperate with the boss, a notch is formed between the fitting part and the support part to accommodate the boss. This ensures that the fitting part directly fits against the side wall of the material cylinder, while the support part acts on the boss, thus realizing the corresponding functions.

[0016] As an optional feature, the end of the support portion is provided with a rounded corner.

[0017] The end of the support is rounded, which facilitates the abutment of the support with the boss when it abuts, and also facilitates the mutual displacement between the support and the boss, thereby reducing the force on the handle and shortening the displacement path of the handle.

[0018] As an optional solution, the support portion includes a first support portion and a second support portion located on both sides of the sealing rod. The first support portion and the second support portion are respectively provided with a first hinge center and a second hinge center that are hinged to the sealing rod. The boss includes a first boss that cooperates with the first support portion and a second boss that cooperates with the second support portion.

[0019] A first support portion and a second support portion are provided on both sides of the sealing rod, which can more evenly push the sealing rod and ensure that the sealing rod can stably switch between the closed position and the discharge position. Correspondingly, a first boss and a second boss are provided, which can not only meet the abutment cooperation with the support portion, but also further distribute the force borne by the boss, ensuring the structural safety and reliability of the material cylinder.

[0020] As an optional solution, the handle is also provided with a clearance groove located between the first support and the second support, and the sealing rod located at the discharge position is accommodated in the clearance groove.

[0021] The handle is further provided with a clearance groove between the first support part and the second support part. On the one hand, when the sealing rod moves from the closed position to the discharge position, the clearance groove can accommodate the sealing rod to ensure that the sealing rod opens the discharge port more fully. On the other hand, the clearance groove can also block the sealing rod to prevent the sealing rod from being pushed too much and affecting its return to the closed position.

[0022] As an optional solution, the rotating base includes a hinge platform located on the side wall of the material cylinder, and the material cylinder also includes a discharge pipe located at the discharge port and extending outward. The side wall of the material cylinder is provided with reinforcing ribs connecting the hinge platform, the discharge pipe and the support base.

[0023] The material cylinder is directly equipped with a hinge platform above the outlet, allowing the sealing rod to be mounted on the hinge platform via the hinge center at the upper end. The sealing element is positioned at the lower end of the sealing rod. Under their own weight, the sealing rod and the sealing element can fit against the outlet to seal it. Further, a discharge pipe is provided, which not only reliably directs the beverage from the material cylinder to the receiving container but also facilitates the insertion of the sealing element into the discharge pipe for more reliable sealing of the outlet.

[0024] As an optional solution, the discharge assembly further includes a torsion spring disposed on the rotating base, the torsion spring abutting against the material cylinder and the sealing rod respectively and pushing the sealing rod to the closed position.

[0025] A torsion spring is further added to push the sealing rod to more reliably ensure that the sealing rod seals the discharge port under normal conditions, thus ensuring the stable and reliable operation of the snow melting machine. Attached Figure Description

[0038] To more clearly illustrate the overall concept of this application, a detailed description is provided below with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant application and not intended to limit the application. Furthermore, it should be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present application will now be described in detail with reference to the accompanying drawings and embodiments. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0040] A typical slush machine usually includes a base and a container mounted on the base. The machine typically includes a compressor, condenser, and evaporator connected by pipes, as well as a stirring paddle and a drive motor to drive the paddle. The evaporator and the stirring paddle are usually located inside the container. The compressor forces refrigerant to circulate within the condenser and evaporator, cooling the food placed in the container through the evaporator. The stirring paddle, driven by the drive motor, rotates and moves the beverage along with it, ensuring even cooling. The user places the beverage into the container, where it is processed by the evaporator and the stirring paddle, and then discharged through a discharge port on the front side of the container. This discharge port is usually located at the bottom of the container, ensuring complete drainage of the beverage without residue, and also allowing for thorough removal of cleaning water during container cleaning.

[0041] The snow melting machine described in this utility model is easy to operate, such as... Figures 1-10 As shown, the snow melting machine includes a base 1, a refrigeration component and a power component disposed within the base 1, and a processing module disposed on the upper part of the base 1. The refrigeration component includes a compressor and a condenser. The processing module includes a material cylinder 21, an evaporator 23, and a stirring paddle 24. The material cylinder 21 is mounted on the base 1 and forms a processing chamber with the base 1. The evaporator 23 is fixed to the base 1 and is in fluid communication with the compressor and the condenser. The refrigerant flows between the compressor, the condenser, and the evaporator to achieve the refrigeration processing of the evaporator. The stirring paddle 24 is sleeved on the outside of the evaporator 23. The stirring paddle 24 and the evaporator 23 are simultaneously housed within the material cylinder 21. The evaporator 23 is used to cool and process the food placed in the material cylinder 21. The power component passes through the evaporator to drive the stirring paddle 24, causing the stirring paddle 24 to tumble the food to make the food processing more uniform.

[0042] A discharge port 212 and a discharge assembly are provided at the bottom of the material cylinder 21. The discharge assembly can open or close the discharge port 212 to meet the normal operation and discharge requirements of the snow melting machine. A rotating base for mounting the discharge assembly is provided on one side of the material cylinder 21. The discharge assembly includes a handle 3, a sealing rod 4, and a sealing element 5. The sealing rod 4 is hinged to the rotating base to be rotatably connected to the material cylinder 21. The sealing element 5 is disposed on the sealing rod 4 and opens or closes the discharge port 212 under the action of the sealing rod 4. The handle 3 is hinged to the sealing rod 4, and pushing the handle 3 to rotate opens or closes the discharge port 212. Here, since the handle 3 is not directly connected to the material cylinder 21, the handle 3 is not in a fixed rotating position when it is in motion, but will slide relative to the material cylinder. The side wall of the material cylinder 21 is also provided with a support seat that abuts against the handle. When the user operates the handle 3, the handle 3 slides against the support seat, so that the handle 3 does not directly act on the side wall of the material cylinder 21.

[0043] The snow melting machine described in this application uses a discharge assembly to control the opening and closing of the discharge port. Compared with the prior art, this application provides a sealing rod hinged to the material cylinder and a handle hinged to the sealing rod. Pushing the sealing rod with the handle ensures reliable sealing of the discharge port and utilizes a two-stage lever effect, allowing the user to easily operate the discharge assembly. Furthermore, a support seat is provided on the side wall of the material cylinder, abutting against the handle. This support seat strengthens the support for the handle, preventing the force of the handle from concentrating on a localized area of ​​the material cylinder, ensuring the strength of the material cylinder, and extending its service life.

[0044] Specifically, as one embodiment of the easy-to-operate snow melting machine described in this utility model, such as... Figures 1-10As shown, the snow melting machine includes a base 1, a refrigeration component and a power component disposed within the base 1. Preferably, a mounting platform 11 is provided at the top of the rear section of the base 1. The refrigeration component includes a compressor and a condenser located within the base 1. The processing module includes a material cylinder 21, a cylinder cover 22, an evaporator 23, and a stirring paddle 24. The material cylinder 21 is horizontally mounted on the top of the base 1, and its rear end is sealed against the mounting platform 11. The rear end of the evaporator 23 is fixedly connected to the mounting platform 11, and the evaporator 23 is in fluid communication with the compressor and the condenser. The stirring paddle 24 is sleeved on the outside of the evaporator 23, and the power component passes through the evaporator 23 to drive the stirring paddle 24. Preferably, the rear end of the feed cylinder 21 is provided with a mounting hole for the evaporator 23 and the agitator 24 to pass through, so that the evaporator 23 and the agitator 24 are accommodated within the feed cylinder 21. The top of the feed cylinder 21 is provided with an opening, and a cylinder cover 22 is provided at the opening to cover the opening of the feed cylinder 21. It is understood that the evaporator and the agitator can also be vertically mounted on the top of the machine base, and the feed cylinder 21 is vertically fitted over the evaporator and the agitator. Alternatively, the feed cylinder can also be directly fixed to the machine base, with only an opening on the front side of the feed cylinder for loading and unloading the agitator.

[0045] The top opening allows the user to add beverages into the mixing tank 21. After processing, the fluid beverage still needs to flow out, so a discharge port 212 is provided at the bottom front side of the mixing tank 21. Simultaneously, the processing material is discharged from the discharge port 212 by the pushing action of the stirring paddle 24. To control the opening and closing of the discharge port 212, a discharge assembly is provided at the discharge port 212. Preferably, the discharge assembly includes a sealing rod 4 hinged to the mixing tank 21 and a handle 3 hinged to the sealing rod 4.

[0046] like Figures 2-4 As shown, a rotating base is provided on the front side of the material cylinder 21. Preferably, the rotating base includes a hinge platform disposed on the side wall of the material cylinder. In this embodiment, the hinge platform includes a first hinge platform 26 and a second hinge platform 27 above the discharge port 212. The first hinge platform 26 and the second hinge platform 27 are provided with a first hinge center 91. The first hinge platform 26 and the second hinge platform 27 are symmetrically arranged. The front side wall of the first hinge platform 26 is provided with a front support rib 261, and the outer side wall is provided with an outer support rib 262. The front support rib 261 and the outer support rib 262 can increase the strength of the first hinge platform 26 and ensure the stability and reliability of the discharge assembly. Correspondingly, the second hinge platform 27 is provided with corresponding front support ribs and outer support ribs.

[0047] The sealing rod 4 is provided with a first hinge post 41, the center of which forms a second hinge center 92. The discharge assembly also includes a rotating fixing post 9 passing through the first hinge post 41, the first hinge platform 26, and the second hinge platform 27, such that the first hinge center 91 and the second hinge center 92 coincide, so that the sealing rod 4 is hinged to the rotating base, and the sealing rod 4 can rotate relative to the material cylinder 21. A sealing cover 43 is provided at the lower end of the sealing rod 4, and a mounting countersunk 44 is provided on the inner side of the sealing cover 43, with a mounting post 45 at the mounting countersunk 44. The sealing element 5 includes a sealing body 51, with a fixing hole 52 on the front side of the sealing body 51, which can be sleeved on the mounting post 45 to fix the sealing element 5 to the sealing rod 4, and an inner protrusion 53 on the rear side of the sealing element 5. The material cylinder 21 has a discharge pipe 211 at the bottom, located at the discharge port 212. The sealing member 5 extends into the discharge pipe 211 through the inner protrusion 53, enhancing the sealing effect on the discharge port 212. The sealing rod 4 is hinged to the material cylinder 21, and the sealing member 5 is provided to close the discharge port. The discharge port can be easily opened or closed by rotating the sealing rod 4, making operation simple and convenient. The discharge assembly also includes a torsion spring 8 located on the rotating base. The torsion spring 8 is sleeved on the outside of the rotating fixed column 9, and abuts against the material cylinder 21 and the sealing rod 4 respectively. In its normal state, the torsion spring 8 pushes the sealing rod 4 to the closed position, closing the discharge port 212. The torsion spring further enhances the sealing effect, ensuring that the discharge assembly stably and reliably seals the discharge port.

[0048] Furthermore, the sealing rod 4 is also provided with a second hinge post 42, which forms a third hinge center 93. The sealing rod 4 is also provided with an inner connecting rib 46 and an outer connecting rib 47 for reinforcing the sealing rod 4. The inner connecting rib 46 and the outer connecting rib 47 are respectively connected to the inner wall and the outer wall of the sealing rod 4 to enhance the strength of the sealing rod 4.

[0049] Preferably, the handle 3 is provided with a first hinge hole 331 and a second hinge hole 332, which form a fourth hinge center 94. The two ends of the second hinge post 42 of the sealing rod 4 are respectively disposed in the first hinge hole 331 and the second hinge hole 332, so that the third hinge center 93 and the fourth hinge center 94 coincide, allowing the handle 3 and the sealing rod 4 to be hinged and rotate relative to each other. The handle 3 includes a gripping part 31 and a supporting part, which are located on both sides of the hinge center of the handle 3. Thus, when the user operates the gripping part 31, it drives the sealing rod 4 to rotate relative to each other, thereby opening or closing the discharge port. Preferably, the support portion includes a first support portion 321 and a second support portion 322 located on both sides of the sealing rod 4, and a clearance groove 36 is formed between the first support portion 321 and the second support portion 322. When the handle 3 rotates the sealing rod 4 to open the discharge port 212, the sealing rod 4 is recessed into the clearance groove 36. This prevents the sealing rod 4 and the sealing element 5 from being directly exposed to the outside, which would make the sealing element 5 susceptible to contamination and affect the hygiene of the final food product.

[0050] The handle 3 also includes a contact portion 34, which is located between the grip portion 31 and the support portion, and is closer to the third hinge center 93 than the grip portion 31 and the support portion. The contact portion 34 further includes a contact surface 341 extending from the end of the support portion towards the grip portion 31. When the handle 3 and the sealing rod 4 are assembled together on the material cylinder 21, the contact surface 341 is in contact with the side wall of the material cylinder 21. The contact surface 341 ensures a stable and reliable fit between the handle 3 and the material cylinder 21 when the handle 3 is in the operating state, i.e., when the discharge assembly is in the closed state with the discharge port closed. The contact portion 34 is located near the third hinge center 93 so that, in the non-operating state, the third hinge center of the handle 3 is as close as possible to the side wall of the material cylinder, thereby ensuring reliable fit and sealing between the sealing rod and the discharge port. Because the contact portion is closer to the hinge center of the handle, when the reaction force of the food inside the cylinder acts on the sealing rod, a lever fulcrum is formed between the sealing rod and the handle at the contact portion. This amplifies the force that pushes the handle away from the closed position, preventing it from being pushed away by the food, thus ensuring the stable and reliable sealing of the dispensing assembly. Furthermore, a handle reinforcing rib 38 is provided on the inner top of the contact surface 341, further increasing the strength of the handle 3.

[0051] Using the handle 3, sealing rod 4, and sealing element 5, the sealing rod and sealing element reliably seal the outlet when sealing is required. When the user operates the discharge assembly to open the outlet, the user operates the gripping part of the handle 3. Since the gripping part and the support part are located at opposite ends, a lever effect is formed between the gripping part and the support part, reducing the force required for the user to operate the gripping part. The support part abuts against the side wall of the material cylinder, and the support part slides relative to the material cylinder, forming a second-level lever effect between the handle and the sealing rod, further reducing the force required for the user to operate the handle to open the outlet. Thus, the discharge assembly reduces the user's opening force while ensuring a sealing effect, making it convenient for the user to operate.

[0052] Based on achieving reliable sealing and convenient operation, this application further provides a support seat on the side wall of the material cylinder 21 that abuts against the handle 3. Preferably, the support seat includes a boss 25 located on the upper side of the discharge pipe 211. In this embodiment, the boss 25 includes a first boss 251 corresponding to the first support part 321 and a second boss 252 corresponding to the second support part 322. When the user operates the handle 3, the first support part 321 abuts against the first boss 251, and the second support part 322 abuts against the second boss 252. At this time, the fitting part 34 separates from the material cylinder 21. By providing the support seat, the force of the support seat does not directly act on the side wall of the material cylinder, avoiding the problem of deformation or even breakage when the material cylinder is subjected to the force of the handle for a long time. This ensures the safe and reliable operation of the material cylinder and extends the service life of the main material cylinder and the snow melting machine.

[0053] To ensure the fit between the support and the boss, and between the mating part and the side wall of the material cylinder, the handle 3 further includes a notch 37 between the mating part 34 and the support. Preferably, the notch 37 is formed at the connection between the first support 321 and the mating surface 341, and between the second support 322 and the mating surface 341. When the handle is installed on the rotating base, the mating surface 341 abuts against the side wall of the material cylinder, the first support 321 with a step abuts against the corresponding first boss 251, and the second support 322 abuts against the corresponding second boss 252. Here, the mating surface 341 only serves to enhance the sealing effect of the sealing rod and has little force on the material cylinder itself. The force of the support is borne by the boss, thus solving the technical problem of excessive and relatively concentrated force on the side wall of the material cylinder.

[0054] Preferably, the boss 25 is further provided with an upper reinforcing rib 253 and a lower reinforcing rib 254 respectively connected to the rotating base and the discharge pipe 211. The upper reinforcing rib 253 and the lower reinforcing rib 254 further distribute the force of the handle more evenly across the various parts of the material cylinder, preventing the material cylinder from bearing excessive force at a single point. This achieves a stable and reliable material cylinder structure without increasing the overall thickness of the material cylinder.

[0055] Specifically, such as Figures 5-10 The image shows the operation of a specific embodiment of the easy-to-operate snow melting machine described in this application.

[0056] like Figure 5 , Figure 7 , Figure 9 The diagram illustrates the interaction between the discharge assembly and the discharge port when the snow melting machine is in a closed state. At this time, the sealing rod 4 drives the sealing element 5 to the closed position, sealing the discharge port 212. Preferably, a portion of the sealing element 5 extends into the discharge pipe 211 to better seal the discharge port 212. The torsion spring 8 pushes the sealing rod 4, ensuring that the sealing rod 4 remains in a sealing state against the sealing pipe. The sealing rod 4 reacts to the handle 3, causing the contact surface 341 to abut against the side wall of the material cylinder 21. Simultaneously, the support portion abuts against the boss 25, or the support portion is close to the boss 25 but not abutting against it. In this state, the torsion spring drives the sealing rod and sealing element to maintain a reliable sealing state, ensuring the reliable sealing of the snow melting machine; while the sealing rod reacts to the handle, and the contact part of the handle is in contact with the side wall of the material cylinder. Since the contact part is close to the first hinge center of the handle, the lever arm of the leverage effect between the contact part and the grip part is extremely short, so it is impossible to push the handle away from the closed position, thereby ultimately maintaining a stable and reliable seal.

[0057] like Figure 6 , Figure 8 , Figure 10As shown, the discharge assembly and discharge port of the snow melting machine are in the engaged state when the user operates to open the discharge port. When the user operates the handle 3, the user pushes the gripping part 31 outward, the fitting part 34 separates from the side wall of the material cylinder 21, the support part abuts against the boss 25, and forms a lever support point. This reduces the force required for the user to operate the gripping part, making it easier for the user to operate. Furthermore, since the support part directly abuts against the boss, it does not exert excessive force on the side wall of the material cylinder, preventing the material cylinder from being excessively squeezed, deformed, or broken. Thus, it not only facilitates user operation but also ensures the structural stability and reliability of the material cylinder and the food processing machine. The handle is hinged to the sealing rod, but not directly to the material cylinder. Therefore, as the handle rotates the sealing rod, the support part slides relative to the boss, thus maintaining a better support point position and reducing the user's operating force. The handle and the sealing rod form a first-level lever effect through their hinge center, which ensures that the sealing rod drives the sealing element quickly and away from the discharge pipe, ensuring that the discharge port can be in the open state to the maximum extent and ensuring the discharge effect.

[0058] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0059] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if a device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures, but this does not imply that the actual device is inverted. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other orientations, rotated 90 degrees, or in other orientations, and the spatial relative descriptions used herein will be interpreted accordingly.

[0060] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special definition and therefore should not be construed as limiting the scope of protection of this application.

[0061] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or equivalent features without departing from the application's concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application will not be listed here.
