Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a sealing structure, a smoothie preparation component, and a smoothie machine. Background Technology

[0002] In the modern catering industry, smoothies are a popular refreshing drink, and smoothie machines are common equipment in many beverage shops and restaurant kitchens. The working principle of a smoothie machine is to continuously scrape the frozen liquid from the evaporator using a stirring device, thereby producing a smooth and delicious smoothie. However, in the actual smoothie-making process, smoothie machines generally suffer from a rather troublesome problem: the mixing drum is prone to leakage, allowing material to enter the machine and cause damage. Utility Model Content

[0003] Therefore, it is necessary to provide a sealing structure, a smoothie preparation component, and a smoothie machine to address the problem of material leakage from the material cylinder into the machine.

[0004] A sealing structure, comprising:

[0005] Rear housing assembly, wherein the rear housing assembly is provided with mounting holes;

[0006] A sealing assembly having a sealing hole is provided on the rear housing assembly. The sealing assembly is arranged circumferentially along the mounting hole. A portion of the sealing assembly is located on a first side of the rear housing assembly, and another portion of the sealing assembly extends through the mounting hole to a second side of the mounting hole. The second side is arranged opposite to the first side.

[0007] A refrigeration tank, wherein the refrigeration tank extends through the sealing hole from the first side of the rear shell assembly and then exits from the second side of the rear shell assembly, and a portion of the sealing assembly is sandwiched between the refrigeration tank and the second side of the rear shell assembly;

[0008] A front housing assembly disposed on and located on a first side of the rear housing assembly, wherein a portion of the sealing assembly is sandwiched between the first side of the rear housing assembly and the front housing assembly.

[0009] The first aspect of this application discloses a sealing structure in which a sealing component is arranged circumferentially along the mounting hole, with a portion located on the first side of the rear housing assembly and another portion extending to the second side, thus forming a circumferential seal around the mounting hole. This design effectively seals the hole. When the refrigeration tank passes through the sealing hole, the sealing component tightly wraps around the refrigeration tank, with a portion sandwiched between the refrigeration tank and the second side of the rear housing assembly, and another portion sandwiched between the first side of the rear housing assembly and the front housing assembly. This tight fit minimizes gaps, achieving a highly efficient seal. Even when the equipment is subjected to vibration or slight deformation, the elasticity of the sealing component maintains a good seal, ensuring the stability of the internal environment of the equipment. The sealing component typically has a certain degree of elasticity, which acts as a buffer when the equipment is subjected to external impacts, absorbing part of the impact force and protecting the rear housing assembly, refrigeration tank, and front housing assembly from damage. For example, during equipment handling or installation, accidental collisions may occur, and the sealing component can effectively mitigate the damage to the internal components of the equipment. The design of this sealing structure makes the installation of each component more convenient. During installation, simply install the sealing assembly precisely around the mounting holes of the rear housing assembly, then pass the refrigeration tank through the sealing holes, and finally install the front housing assembly. This modular installation method reduces installation complexity and improves production efficiency. When equipment maintenance or repair is required, the connections between components are relatively independent due to the presence of the sealing assembly. The front housing assembly can be easily disassembled for inspection and replacement of the refrigeration tank and sealing assembly. If the sealing assembly is damaged, it can be replaced individually without large-scale disassembly of the entire equipment, reducing maintenance costs and time.

[0010] In one embodiment, the sealing assembly has a first sealing groove surrounding the sealing hole, and a portion of the rear housing assembly extends into the first sealing groove. This design, with the first sealing groove surrounding the sealing hole and a portion of the rear housing assembly extending into it, creates an additional sealing barrier. The first sealing groove further enhances the sealing effect on top of the existing seals between the sealing assembly and the rear housing assembly, the refrigeration tank, and the front housing assembly. The presence of the first sealing groove increases the contact area between the rear housing assembly and the sealing assembly, allowing for a tighter fit. The extension of the rear housing assembly into the first sealing groove not only provides a seal but also strengthens the mechanical connection between them. This connection method is similar to a mortise and tenon joint, increasing the friction and interlocking force between the components. When the equipment is subjected to external impact or vibration, relative displacement between the rear housing assembly and the sealing assembly is less likely to occur.

[0011] In one embodiment, the sealing assembly includes a sealing ring, a first sealing plate, a connecting portion, an extension portion, and a second sealing plate. The sealing ring has the sealing hole. The first sealing plate and the connecting portion are disposed on the sealing ring and located on both sides of the sealing ring. One side of the extension portion is connected to the side of the connecting portion away from the sealing ring. The second sealing plate is disposed on the extension portion and located on the side of the extension portion away from the connecting portion. The sealing ring, the connecting portion, and the extension portion cooperate to form a first sealing groove. Composed of multiple components including the sealing ring, the first sealing plate, the connecting portion, the extension portion, and the second sealing plate, these components work together to form a multi-layered sealing structure. The sealing ring surrounds the refrigeration tank, directly sealing the gap between the refrigeration tank and the rear shell assembly, preventing external substances from entering the equipment through this gap. The first and second sealing plates are located in different positions, further enhancing the sealing effect and preventing dust, moisture, and other impurities from entering from different directions. The first sealing groove formed by the sealing ring, the connecting portion, and the extension portion extends into the rear shell assembly. This structure increases the length and complexity of the sealing path, requiring substances to bypass the first sealing groove, thereby greatly improving the reliability of the seal. The first sealing plate and the connecting part are located on both sides of the sealing ring, the extension is connected to the connecting part, and the second sealing plate is located on the extension. This tight connection makes the sealing assembly a whole.

[0012] In one embodiment, the rear housing assembly has a second sealing groove surrounding the first sealing groove, and a second sealing plate extends to the second sealing groove, sandwiched between the front housing assembly and the rear housing assembly. The second sealing groove surrounding the first sealing groove, and the second sealing plate extending to the second sealing groove and sandwiched between the front and rear housing assemblies, forms an additional sealing barrier. This significantly increases the difficulty for external dust, moisture, humidity, and harmful gases to enter the equipment. The second sealing groove and the second sealing plate extend the sealing path. External substances must bypass the second sealing groove and then pass through the first sealing groove to enter the equipment, making the seal more reliable. This extended sealing path, like a maze, increases the resistance to material penetration, further improving sealing performance. The second sealing plate sandwiched between the front and rear housing assemblies strengthens the connection between them. This allows the two components to work together better during operation, reducing relative displacement caused by external forces such as vibration and impact. For example, during equipment transportation, it may be subject to bumps and collisions. The presence of the second sealing plate can effectively buffer these external forces, ensuring that the front shell assembly and the rear shell assembly will not loosen or separate, thus guaranteeing the stability of the entire equipment structure.

[0013] In one embodiment, the first sealing piece is located on the second side, the sealing ring is located at the mounting hole, and the connecting portion, the extension portion, and the second sealing piece are located on the first side;

[0014] In one embodiment, the second sealing groove is located on the first side.

[0015] In one embodiment, the sealing assembly further includes multiple connectors, which are disposed on the second sealing sheet and spaced apart circumferentially along the second sealing sheet. The rear housing assembly has multiple limiting holes, each corresponding to one of the connectors. Each connector passes through one of the limiting holes and extends to the second side of the rear housing assembly. By having multiple connectors spaced circumferentially along the second sealing sheet and extending through the corresponding limiting holes to the second side of the rear housing assembly, the second sealing sheet can fit more tightly against the rear housing assembly. During equipment operation, even under the influence of vibration, temperature changes, etc., the cooperation between the connectors and the limiting holes prevents the second sealing sheet from shifting or deforming, thus maintaining a good sealing condition. The one-to-one correspondence between the multiple connectors and the limiting holes forms a continuous sealing barrier at the connection between the second sealing sheet and the rear housing assembly. This continuous sealing structure effectively prevents external substances from entering through the gaps between the connectors and the limiting holes, further improving the reliability of the seal. Compared to using a single connector, using multiple connectors spaced circumferentially can better distribute stress, resulting in a more uniform sealing effect.

[0016] In one embodiment, the sealing ring includes a sealing ring body and a first sealing rib. The sealing ring body is sandwiched between the wall of the mounting hole and the outer wall of the refrigeration tank. The first sealing rib is disposed on the sealing ring body and located between the sealing ring body and the outer wall of the refrigeration tank. The sealing ring body, sandwiched between the wall of the mounting hole and the outer wall of the refrigeration tank, forms a first line of defense, effectively preventing external dust, water vapor, moisture, and other impurities from entering the equipment and avoiding damage to the refrigeration tank and other components inside the equipment. The first sealing rib, disposed on the sealing ring body and located between the sealing ring body and the outer wall of the refrigeration tank, further enhances the sealing effect, forming a second line of defense. This double-sealing structure greatly increases the difficulty for external substances to enter the equipment and improves the reliability of the seal. For example, in a humid outdoor environment, it can effectively prevent water vapor from penetrating into the refrigeration tank, ensuring the stability of the refrigeration effect. The first sealing rib has a certain degree of elasticity; during installation, it deforms under the pressure of the outer wall of the refrigeration tank, thus fitting more tightly against the outer wall of the refrigeration tank. This tight fit fills any tiny gaps that may exist between the sealing ring body and the refrigeration tank, reducing the possibility of leakage. Even if the refrigeration tank changes size due to thermal expansion and contraction during equipment operation, the first sealing rib can maintain a good seal through its own elastic deformation.

[0017] In one embodiment, the extension includes an extension body and a second sealing rib. The extension body is sandwiched between the rear housing assembly and the front housing assembly, and the second sealing rib is disposed on the extension body, located between the extension body and the front housing assembly. The extension body, sandwiched between the rear and front housing assemblies, forms a basic sealing layer, effectively preventing external dust, moisture, and humidity from entering the equipment and protecting internal components from environmental influences. The second sealing rib, positioned between the extension body and the front housing assembly, acts as an additional sealing barrier, further enhancing the sealing effect. This double-sealing structure significantly improves sealing reliability, effectively preventing dust and moisture from intruding into the equipment, especially in dusty or humid outdoor environments, ensuring normal equipment operation. The second sealing rib typically has a certain degree of elasticity; during installation of the front housing assembly, it deforms under pressure, thus tightly fitting the surface of the front housing assembly. This tight fit fills any small gaps that may exist between the extension body and the front housing assembly, reducing the possibility of leakage. Even when the relative positions of the rear and front housing components change slightly due to prolonged use or exposure to factors such as vibration and temperature variations, the second sealing rib can maintain a good seal through its own elastic deformation.

[0018] In one embodiment, the rear shell assembly includes a rear shell body, a sealing ring, and a limiting rib. The rear shell body has the mounting hole, with one side being the first side and the other side being the second side. The sealing ring is disposed on the rear shell body and located on the first side, surrounding the mounting hole. The limiting rib is disposed on the rear shell body and located outside the sealing ring, forming a second sealing groove between the sealing ring and the limiting rib. The sealing assembly is sleeved on the sealing ring and partially extends into the second sealing groove. By having the sealing ring surround the mounting hole and the sealing assembly sleeved on it, the sealing assembly and the sealing ring fit tightly together, forming an effective seal against the mounting hole. This prevents external dust, moisture, and other impurities from entering the equipment through the mounting hole, protecting critical components such as the refrigeration tank. Simultaneously, the second sealing groove formed between the sealing ring and the limiting rib, with the sealing assembly partially extending into the second sealing groove, further enhances the sealing effect. For external substances to enter the equipment, they must first overcome the seal between the sealing component and the sealing ring, and then pass through the barrier of the second sealing groove, greatly increasing the difficulty of intrusion and achieving multiple layers of sealing protection. The design of the sealing ring allows for more precise positioning and installation of the sealing component, ensuring a tighter fit between the sealing component and the rear housing body. Furthermore, the annular structure of the sealing ring can apply pressure evenly to the sealing component, maintaining a good seal throughout its entire circumference and preventing leakage problems caused by poor local sealing. For example, when the equipment is subjected to vibration or temperature changes, the sealing ring can better maintain the position and shape of the sealing component, ensuring the stability of the sealing performance.

[0019] In one embodiment, the refrigeration tank includes a refrigeration tank body and a sealing plate. A portion of the refrigeration tank body extends through the sealing hole from a first side of the rear shell assembly and then protrudes from a second side of the rear shell assembly. The sealing plate is disposed on the refrigeration tank body, located at the end of the refrigeration tank body extending to the second side and surrounding the refrigeration tank body. A portion of the sealing assembly is sandwiched between the sealing plate and the second side of the rear shell assembly. The refrigeration tank body passing through the sealing hole of the sealing assembly, with the sealing plate surrounding the refrigeration tank body at its end extending to the second side of the rear shell assembly and a portion of the sealing assembly sandwiched between the sealing plate and the second side of the rear shell assembly, forms a sealing barrier. The cooperation between the sealing plate, the sealing assembly, and the rear shell assembly effectively fixes the position of the refrigeration tank. It restricts the axial and radial displacement of the refrigeration tank, making the refrigeration tank more stable during operation. During operation, the refrigeration tank may vibrate due to pressure changes and refrigerant flow in the refrigeration cycle. The connection between the sealing plate and the sealing assembly can disperse these vibrations onto the rear shell assembly, reducing the impact on the refrigeration tank's own structure and other related components, and extending the service life of the refrigeration tank.

[0020] In one embodiment, the front shell assembly includes a front shell body and a feed shell. The front shell body has an adapter port and is disposed on the rear shell assembly. The sealing assembly is sandwiched between the front shell body and the rear shell assembly. The refrigeration tank passes through the adapter port. The feed shell is disposed on the front shell body and has a feed buffer groove. The feed buffer groove has feed inlets on its side and bottom. By having the front shell body disposed on the rear shell assembly and the sealing assembly sandwiched between them, the overall sealing performance of the equipment is further enhanced. The sealing assembly can effectively prevent substances from entering the equipment, protecting the refrigeration tank and other precision components inside the equipment from the influence of the external environment. The feed buffer groove on the feed shell buffers the feed. The feed inlets on the side and bottom of the feed buffer groove allow material to enter the equipment evenly from multiple directions and contact the refrigeration tank.

[0021] A smoothie preparation component, comprising:

[0022] The aforementioned sealing structure;

[0023] An outer sleeve assembly is disposed on the front shell assembly, and the outer sleeve assembly and the front shell assembly enclose a working space, with the portion of the refrigeration tank located on the first side situated within the working space. The outer sleeve assembly has a discharge port.

[0024] A stirring assembly, which is sleeved on the refrigeration tank and located within the working space;

[0025] A valve body assembly is disposed on the outer sleeve assembly, and the valve body assembly is capable of opening or closing the discharge port.

[0026] The second aspect of this application discloses a slush preparation assembly. Utilizing a sealed structure, the refrigeration chamber can efficiently cool the slush in a stable environment. An outer sleeve assembly and a front shell assembly enclose a working space, enclosing the portion of the refrigeration chamber located on the first side, providing a relatively enclosed and temperature-controlled environment for slush preparation. A stirring assembly is fitted onto the refrigeration chamber and located within the working space, allowing for thorough stirring of the materials surrounding the refrigeration chamber. The low temperature of the refrigeration chamber rapidly cools the materials, while the continuous stirring of the stirring assembly ensures uniform cooling. The combined effect of these two elements significantly improves the efficiency of slush preparation. A valve assembly is mounted on the outer sleeve assembly and can precisely open or close the discharge port. After slush preparation is complete, the operator can easily operate the valve assembly to allow the slush to flow smoothly from the discharge port as needed. This convenient discharge control avoids slush waste and facilitates the loading of slush into different containers, improving the overall smoothness of the slush preparation process.

[0027] A smoothie maker, comprising:

[0028] The above-mentioned components for preparing smoothies.

[0029] The third aspect of this application discloses a smoothie machine that provides good sealing performance through the use of smoothie preparation components, which can prevent the smoothie from being contaminated during the preparation process. Moreover, the good sealing performance provides a reliable working environment and prevents internal components from being affected by the penetrating liquid, thus avoiding a reduction in lifespan.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0052] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0053] The sealing structure, smoothie preparation components, and smoothie machine of some embodiments of the present invention are described below with reference to the accompanying drawings.

[0054] Example 1

[0055] like Figures 1 to 12 As shown, this embodiment discloses a sealing structure, including:

[0056] Rear housing assembly 1, the rear housing assembly 1 is provided with mounting holes 101;

[0057] The sealing component 2 has a sealing hole 201. The sealing component 2 is disposed on the rear housing component 1. The sealing component 2 is arranged around the mounting hole 101. A portion of the sealing component 2 is located on the first side of the rear housing component 1. Another portion of the sealing component 2 passes through the mounting hole 101 and extends to the second side of the mounting hole 101. The second side is disposed opposite to the first side.

[0058] The refrigeration tank 3 passes through the sealing hole 201 from the first side of the rear shell assembly 1 and then exits from the second side of the rear shell assembly 1. A portion of the sealing assembly 2 is sandwiched between the refrigeration tank 3 and the second side of the rear shell assembly 1.

[0059] The front shell assembly 4 is disposed on the rear shell assembly 1 and located on the first side of the rear shell assembly 1, and a portion of the sealing assembly 2 is sandwiched between the first side of the rear shell assembly 1 and the front shell assembly 4.

[0060] The first aspect of this application discloses a sealing structure in which a sealing component 2 is arranged circumferentially along the mounting hole 101, with a portion located on the first side of the rear housing assembly 1 and the other portion extending to the second side, thus forming a circumferential seal around the mounting hole 101. This design effectively seals the device. When the refrigeration tank 3 passes through the sealing hole 201, the sealing component 2 tightly wraps around the refrigeration tank 3, with a portion sandwiched between the refrigeration tank 3 and the second side of the rear housing assembly 1, and the other portion sandwiched between the first side of the rear housing assembly 1 and the front housing assembly 4. This tight fit minimizes gaps, thereby achieving a highly efficient seal. Even when the equipment is subjected to vibration or slight deformation, the elasticity of the sealing component 2 maintains a good seal, ensuring the stability of the internal environment of the equipment. The sealing component 2 typically has a certain degree of elasticity, which acts as a buffer when the equipment is subjected to external impact, absorbing part of the impact force and protecting the rear housing assembly 1, the refrigeration tank 3, and the front housing assembly 4 from damage. For example, during equipment handling or installation, accidental collisions may occur, and the sealing component 2 can effectively mitigate the damage to the internal components of the equipment. The design of this sealing structure makes the installation of each component more convenient. During installation, simply install the sealing component 2 precisely around the mounting holes 101 of the rear housing component 1, then pass the refrigeration tank 3 through the sealing holes 201, and finally install the front housing component 4. This modular installation method reduces installation complexity and improves production efficiency. When maintenance or repair is required, the connections between components are relatively independent due to the presence of the sealing component 2. The front housing component 4 can be easily disassembled for inspection and replacement of the refrigeration tank 3 and the sealing component 2. If the sealing component 2 is damaged, it can be replaced individually without large-scale disassembly of the entire equipment, reducing maintenance costs and time.

[0061] like Figure 8 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the sealing assembly 2 is provided with a first sealing groove 202, the first sealing groove 202 surrounds the sealing hole 201, and a portion of the rear shell assembly 1 extends into the first sealing groove 202. By having the first sealing groove 202 surround the sealing hole 202, and the portion of the rear shell assembly 1 extending into the first sealing groove 202, this design forms an additional sealing barrier. Based on the original sealing between the sealing assembly 2 and the rear shell assembly 1, the refrigeration tank 3, and the front shell assembly 4, the first sealing groove 202 further enhances the sealing effect. The presence of the first sealing groove 202 increases the contact area between the rear shell assembly 1 and the sealing assembly 2, allowing them to fit more tightly. The portion of the rear shell assembly 1 extending into the first sealing groove 202 not only provides a sealing effect but also enhances the mechanical connection between the rear shell assembly 1 and the sealing assembly 2. This connection method is similar to a mortise and tenon structure, increasing the friction and interlocking force between the components. When the equipment is subjected to external impact or vibration, relative displacement between the rear shell assembly 1 and the sealing assembly 2 is less likely to occur.

[0062] like Figure 8 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further defines: the sealing assembly 2 includes a sealing ring 21, a first sealing plate 22, a connecting portion 23, an extension portion 24, and a second sealing plate 25. The sealing ring 21 has a sealing hole 201. The first sealing plate 22 and the connecting portion 23 are disposed on the sealing ring 21 and located on both sides of the sealing ring 21. One side of the extension portion 24 is connected to the side of the connecting portion 23 away from the sealing ring 21. The second sealing plate 25 is disposed on the extension portion 24 and located on the side of the extension portion 24 away from the connecting portion 23. The sealing ring 21, the connecting portion 23, and the extension portion 24 cooperate to form a first sealing groove 202. Composed of multiple components including the sealing ring 21, the first sealing plate 22, the connecting portion 23, the extension portion 24, and the second sealing plate 25, the components work together to form a multi-layered sealing structure. The sealing ring 21 surrounds the refrigeration tank 3 and directly seals the gap between the refrigeration tank 3 and the rear shell assembly 1, preventing external substances from entering the equipment through this gap. The first sealing plate 22 and the second sealing plate 25 are located at different positions, further enhancing the sealing effect and preventing dust, moisture, and other impurities from entering from different directions. The sealing ring 21, the connecting portion 23, and the extension portion 24 cooperate to form a first sealing groove 202, into which a portion of the rear housing assembly 1 extends. This structure increases the length and complexity of the sealing path, requiring materials to bypass the first sealing groove 202, thereby greatly improving the reliability of the seal. The first sealing plate 22 and the connecting portion 23 are located on both sides of the sealing ring 21, the extension portion 24 connects to the connecting portion 23, and the second sealing plate 25 is located on the extension portion 24. This tight connection makes the sealing assembly 2 a single unit.

[0063] like Figure 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the rear shell assembly 1 is provided with a second sealing groove 102, the second sealing groove 102 surrounds the first sealing groove 202, and a second sealing plate 25 extends to the second sealing groove 102, sandwiched between the front shell assembly 4 and the rear shell assembly 1. By having the second sealing groove 102 surround the first sealing groove 202, and the second sealing plate 25 extend to the second sealing groove 102 and sandwiched between the front shell assembly 4 and the rear shell assembly 1, an additional sealing barrier is formed. This greatly increases the difficulty for external dust, water vapor, moisture, and harmful gases to enter the equipment. The arrangement of the second sealing groove 102 and the second sealing plate 25 extends the sealing path. External substances need to bypass the second sealing groove 102 and then pass through the first sealing groove 202 to enter the equipment, making the seal more reliable. This extended sealing path, like a maze, increases the resistance to material penetration and further improves the sealing performance. The second sealing plate 25 is sandwiched between the front housing assembly 4 and the rear housing assembly 1, strengthening the connection between them. This allows the two components to work together more effectively during operation, reducing relative displacement caused by external forces such as vibration and impact. For example, during equipment transportation, it may be subjected to bumps and collisions; the presence of the second sealing plate 25 can effectively buffer these external forces, ensuring that the front housing assembly 4 and the rear housing assembly 1 do not loosen or separate, thus guaranteeing the stability of the entire equipment structure.

[0064] In addition to the features of the above embodiments, this embodiment further specifies that: the first sealing plate 22 is located on the second side, the sealing ring 21 is located at the mounting hole 101, and the connecting part 23, the extension part 24 and the second sealing plate 25 are located on the first side;

[0065] In addition to the features of the above embodiments, this embodiment further specifies that the second sealing groove 102 is located on the first side.

[0066] like Figure 8 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the sealing assembly 2 also includes multiple connectors 26, which are disposed on the second sealing sheet 25 and spaced apart circumferentially along the second sealing sheet 25. The rear shell assembly 1 is provided with multiple limiting holes 103, which are correspondingly disposed one-to-one with the multiple connectors 26. The multiple connectors 26 extend to the second side of the rear shell assembly 1 after passing through the multiple limiting holes 103. By having multiple connectors 26 spaced apart circumferentially along the second sealing sheet 25 and extending to the second side of the rear shell assembly 1 through the corresponding limiting holes 103, the second sealing sheet 25 can fit more tightly onto the rear shell assembly 1. During equipment operation, even under the influence of factors such as vibration and temperature changes, the cooperation between the connector 26 and the limiting hole 103 prevents the second sealing plate 25 from shifting or deforming, thus maintaining a good sealing state. The one-to-one correspondence between multiple connectors 26 and the limiting hole 103 forms a continuous sealing barrier at the connection between the second sealing plate 25 and the rear housing assembly 1. This continuous sealing structure effectively prevents external substances from entering through the gap between the connector 26 and the limiting hole 103, further improving the reliability of the seal. Compared to the arrangement of a single connector, the circumferentially spaced arrangement of multiple connectors 26 better disperses stress, resulting in a more uniform sealing effect.

[0067] In addition to the features of the above embodiments, this embodiment further specifies that: the sealing ring 21 includes a sealing ring body and a first sealing rib. The sealing ring body is sandwiched between the wall of the mounting hole 101 and the outer wall of the refrigeration tank 3. The first sealing rib is disposed on the sealing ring body and located between the sealing ring body and the outer wall of the refrigeration tank 3. By sandwiching the sealing ring body between the wall of the mounting hole 101 and the outer wall of the refrigeration tank 3, a first sealing barrier is formed, which can effectively prevent external dust, water vapor, moisture and other impurities from entering the equipment and avoid damage to the refrigeration tank 3 and other components inside the equipment. The first sealing rib is disposed on the sealing ring body and located between the sealing ring body and the outer wall of the refrigeration tank 3, which further enhances the sealing effect and constitutes a second sealing barrier. This double sealing structure greatly increases the difficulty for external substances to enter the equipment and improves the reliability of the seal. For example, in a humid outdoor environment, it can effectively prevent water vapor from penetrating into the interior of the refrigeration tank 3 and ensure the stability of the refrigeration effect. The first sealing rib has a certain degree of elasticity. During installation, it deforms under the pressure of the outer wall of the refrigeration tank 3, thus fitting more tightly against the outer wall of the refrigeration tank 3. This tight fit can fill any tiny gaps that may exist between the sealing ring body and the refrigeration tank 3, reducing the possibility of leakage. Even if the refrigeration tank 3 changes size due to thermal expansion and contraction during equipment operation, the first sealing rib can maintain a good seal through its own elastic deformation.

[0068] In addition to the features of the above embodiments, this embodiment further defines: the extension 24 includes an extension body and a second sealing rib. The extension body is sandwiched between the rear shell assembly 1 and the front shell assembly 4, and the second sealing rib is disposed on the extension body and located between the extension body and the front shell assembly 4. The extension body sandwiched between the rear shell assembly 1 and the front shell assembly 4 forms a basic sealing layer, effectively preventing external dust, water vapor, and moisture from entering the equipment and protecting the internal components from external environmental influences. The second sealing rib, located between the extension body and the front shell assembly 4, acts as an additional sealing barrier, further enhancing the sealing effect. This double-sealing structure greatly improves the reliability of the seal. For example, in dusty or humid outdoor environments, it can more effectively prevent dust and water vapor from intruding into the equipment, ensuring the normal operation of the equipment. The second sealing rib typically has a certain degree of elasticity. When the front shell assembly 4 is installed, it is compressed and deformed, thus tightly fitting the surface of the front shell assembly 4. This tight fit can fill any small gaps that may exist between the extension body and the front shell assembly 4, reducing the possibility of leakage. Even when the relative positions of the rear shell assembly 1 and the front shell assembly 4 change slightly due to prolonged use of the equipment or the influence of factors such as vibration and temperature changes, the second sealing rib can continue to maintain a good sealing state through its own elastic deformation.

[0069] like Figure 7As shown, in addition to the features of the above embodiments, this embodiment further defines: the rear shell assembly 1 includes a rear shell body 11, a sealing ring 12, and a limiting rib 13. The rear shell body 11 is provided with a mounting hole 101. One side of the rear shell body 11 is a first side, and the other side of the rear shell body 11 is a second side. The sealing ring 12 is disposed on the rear shell body 11 and located on the first side, surrounding the mounting hole 101. The limiting rib 13 is disposed on the rear shell body 11 and located outside the sealing ring 12. A second sealing groove 102 is formed between the sealing ring 12 and the limiting rib 13. The sealing component 2 is sleeved on the sealing ring 12 and partially extends to the second sealing groove 102. By the sealing ring 12 surrounding the mounting hole 101 and the sealing component 2 being sleeved on the sealing ring 12, the sealing component 2 and the sealing ring 12 are tightly fitted, forming an effective seal against the mounting hole 101. This prevents external dust, moisture, and other impurities from entering the equipment through the mounting hole 101, protecting key components such as the refrigeration tank 3. Meanwhile, the second sealing groove 102 formed between the sealing ring 12 and the limiting rib 13, with the sealing component 2 extending to the second sealing groove 102, further enhances the sealing effect. For external substances to enter the equipment, they must first overcome the seal between the sealing component 2 and the sealing ring 12, and then pass through the barrier of the second sealing groove 102, greatly increasing the difficulty of intrusion and achieving multiple layers of sealing protection. The design of the sealing ring 12 allows for more precise positioning and installation of the sealing component 2, ensuring a tighter fit between the sealing component 2 and the rear housing body 11. Furthermore, the annular structure of the sealing ring 12 can evenly apply pressure to the sealing component 2, ensuring a good seal throughout the entire circumference and preventing leakage problems caused by poor local sealing. For example, when the equipment is subjected to vibration or temperature changes, the sealing ring 12 can better maintain the position and shape of the sealing component 2, ensuring the stability of the sealing performance.

[0070] like Figure 2 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further defines: the refrigeration tank 3 includes a refrigeration tank body 31 and a sealing plate 32. A portion of the refrigeration tank body 31 passes through the sealing hole 201 from the first side of the rear shell assembly 1 and then extends out from the second side of the rear shell assembly 1. The sealing plate 32 is disposed on the refrigeration tank body 31, located on the end of the refrigeration tank body 31 extending to the second side and surrounding the refrigeration tank body 31. A portion of the sealing assembly 2 is sandwiched between the sealing plate 32 and the second side of the rear shell assembly 1. The refrigeration tank body 31 passes through the sealing hole 201 of the sealing assembly 2, and the sealing plate 32 surrounds the refrigeration tank body 31 at the end extending to the second side of the rear shell assembly 1, with a portion of the sealing assembly 2 sandwiched between the sealing plate 32 and the second side of the rear shell assembly 1, forming a sealing barrier. The cooperation between the sealing plate 32, the sealing assembly 2, and the rear shell assembly 1 effectively fixes the position of the refrigeration tank 3. It restricts the axial and radial displacement of the refrigeration tank 3, making the refrigeration tank 3 more stable during operation. When the refrigeration tank 3 is working, it may vibrate due to pressure changes and refrigerant flow in the refrigeration cycle. The connection between the sealing plate 32 and the sealing component 2 can disperse these vibrations onto the rear shell component 1, reducing the impact on the structure of the refrigeration tank 3 and other related components, and extending the service life of the refrigeration tank 3.

[0071] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines: the front shell assembly 4 includes a front shell body 41 and a feed shell 42. The front shell body 41 is provided with an adapter port 401 and is disposed on the rear shell assembly 1. The sealing assembly 2 is sandwiched between the front shell body 41 and the rear shell assembly 1. The refrigeration tank 3 passes through the adapter port 401. The feed shell 42 is disposed on the front shell body 41 and is provided with a feed buffer groove 402. The feed buffer groove 402 has feed ports 403 on its side and bottom. By having the front shell body 41 disposed on the rear shell assembly 1 and the sealing assembly 2 sandwiched between the two, the overall sealing performance of the equipment is further enhanced. The sealing assembly 2 can effectively prevent substances from entering the equipment and protect the refrigeration tank 3 and other precision components inside the equipment from the influence of the external environment. The feed buffer groove 402 provided on the feed shell 42 plays a role in buffering the feed. The feed inlets 403 on the side and bottom of the feed buffer tank 402 allow the material to enter the equipment and contact the refrigeration tank 3 evenly from multiple directions.

[0074] The aforementioned sealing structure 100;

[0075] An outer sleeve assembly 200 is mounted on the front shell assembly 4. The outer sleeve assembly 200 and the front shell assembly 4 enclose a working space, and the portion of the refrigeration tank 3 located on the first side is situated within this working space. The outer sleeve assembly 200 is provided with a discharge port 2001.

[0076] A stirring assembly 300 is mounted on the refrigeration tank 3 and located within the working space.

[0077] Valve body assembly 400 is disposed on outer sleeve assembly 200 and is capable of opening or closing discharge port 2001.

[0078] The second aspect of this application discloses a slush preparation assembly. Utilizing a sealed structure 100, the refrigeration chamber 3 can efficiently cool in a stable environment. An outer sleeve assembly 200 and a front shell assembly 4 enclose a working space, enclosing the portion of the refrigeration chamber 3 located on its first side, providing a relatively enclosed and temperature-controlled environment for slush preparation. A stirring assembly 300 is fitted onto the refrigeration chamber 3 and located within the working space, allowing for thorough stirring of the materials surrounding the refrigeration chamber 3. The low temperature of the refrigeration chamber 3 rapidly cools the materials, while the continuous stirring of the stirring assembly 300 ensures uniform cooling. The combined effect of these two elements significantly improves the efficiency of slush preparation. A valve assembly 400 is mounted on the outer sleeve assembly 200 and can precisely open or close the discharge port 2001. After slush preparation is complete, the operator can easily operate the valve assembly 400 according to actual needs, allowing the slush to flow smoothly from the discharge port 2001. This convenient discharge control avoids slush waste and facilitates the loading of slush into different containers, improving the overall smoothness of the slush preparation process.
