Description

Technical Field

[0001] This utility model relates to the field of cold drink equipment technology, and in particular to a sealing device for cold drink equipment and cold drink equipment. Background Technology

[0002] With the upgrading of consumption and the development of food processing technology, the popularity of cold drink equipment in homes, restaurants, and commercial settings is increasing. This type of equipment completes the process of making cold drinks such as slushies and slushies through an ice-making chamber. The ice-making chamber of existing cold drink equipment generally adopts a composite structure of "outer shell + evaporator". That is, the evaporator, as the core refrigeration component, is set inside the ice-making chamber surrounded by the outer shell. Through the contact between the evaporator and liquids such as juice and milk, it absorbs the heat from the liquid, causing the liquid to freeze quickly and form slushies.

[0003] In refrigerated beverage equipment, the evaporator cylinder is rotatably mounted on both sides of the ice-making chamber. A drive motor located outside the ice-making chamber rotates the evaporator cylinder to prepare slushies. During the slushy-making process, to prevent leakage of water from the raw materials or slushies from the gap between the evaporator cylinder and the ice-making chamber, sealing rings are installed at both ends of the evaporator cylinder. These sealing rings are located at the end pivot of the evaporator cylinder and on the inner wall of the outer casing, forming a pivot seal. This sealing structure design effectively prevents water from the raw materials or slushies from leaking to the outside of the ice-making chamber.

[0004] However, currently used sealing rings are generally one-piece structures. Because these rings wear down over time, their sealing effect decreases or they fail, requiring periodic replacement. This design makes replacement extremely cumbersome. The sealing ring is fitted onto the outside of the end shaft of the evaporator cylinder, which is rotatably mounted on both sides of the ice-making chamber and connected to the drive motor. To replace the sealing ring, the entire evaporator cylinder must be removed from the ice-making chamber before the old sealing ring can be removed, the new one fitted, and the cylinder reinstalled. This process not only consumes a significant amount of time and manpower but also risks unnecessary damage to the evaporator cylinder, the inner wall of the ice-making chamber, or other related components during disassembly and reinstallation, further increasing maintenance costs and the risk of equipment failure.

Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0049] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0050] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] like Figures 1 to 6As shown, this embodiment provides a sealing device for a cold drink equipment, including an inner liner 1, a feeding mechanism 2, and a sealing assembly 3. The inner liner 1 and the feeding mechanism 2 are detachably installed on the housing of the cold drink equipment (not shown in the figure). The inner liner 1 and the feeding mechanism 2 enclose a chamber 4. An evaporator 5 is rotatably installed in the chamber 4, and the rotating shaft on one side of the evaporator 5 passes through the chamber 4 and is connected to an external drive motor. The evaporator 5 rotates in the chamber 4 to prepare smoothies or ice cream.

[0052] The sealing assembly 3 includes a first sealing element 31 and a second sealing element 32. The first sealing element 31 is detached and installed on the inner liner 1, and the second sealing element 32 is detached and installed on the feeding mechanism 2. The first sealing element 31 and the second sealing element 32 form a sealing structure, which is used to seal the gap between the chamber 4 and the evaporator 5.

[0053] This embodiment of the sealing device for a cold drink equipment completely changes the traditional integrated sealing ring structure where the sealing assembly 3 is fitted onto the end shaft of the evaporator cylinder, by splitting the sealing component 3 into a first sealing element 31 and a second sealing element 32, which are respectively installed on the detachable inner liner 1 and the feeding mechanism 2. This significantly simplifies the replacement process of the sealing elements. In this embodiment, both ends of the evaporator are rotatably mounted on the inner shell of the cold drink equipment through the chamber 4, and one end of the evaporator is connected to the drive motor. When the sealing assembly 3 needs to be replaced, it is not necessary to remove the entire evaporator cylinder from the chamber 4. Only the inner liner 1 and the feeding mechanism 2 need to be removed, and the first sealing element 31 and the second sealing element 32 can be removed from the evaporator at the same time. This allows for the observation of the wear condition of the first sealing element 31 and the second sealing element 32 while cleaning the inner liner 1 and the feeding mechanism 2, and the replacement of the first sealing element 31 or the second sealing element 32 with severe wear. This design significantly saves the time and labor costs required for replacement. Meanwhile, this split structure also facilitates the cleaning of the first seal 31 or the second seal 32. During use, the first seal 31 can be removed with the inner liner 1, and the second seal 32 can be removed with the feeding mechanism 2. While cleaning the inner liner 1 and the feeding mechanism 2, it is convenient to thoroughly clean the two seals, avoiding the impact of raw material residue on the sealing effect and equipment hygiene.

[0054] By avoiding the complete disassembly and reinstallation of the evaporator, the possibility of unnecessary damage to the evaporator, the inner wall of chamber 4, and other related components during operation is reduced, thereby lowering equipment maintenance costs and the risk of failure due to component damage. Furthermore, the annular sealing structure formed by the first seal 31 and the second seal 32 can reliably seal the gap between chamber 4 and the evaporator, effectively preventing water leakage after the raw materials or ice melt during long-term use. The modular design allows for individual seal replacement after wear, eliminating the need to replace the entire sealing assembly 3, further improving the convenience and economy of seal maintenance and ensuring the sealing performance of the equipment during long-term use.

[0055] In one embodiment, the first seal 31 includes a first seal body 311 and a first seal portion 312, wherein one end of the first seal body 311 is radially recessed to form a first recess 315 for wrapping the upper part of the evaporator;

[0056] The first sealing portion 312 is a flange formed by the first sealing element body 311 extending outward along the circumferential contour of the first recess 315. The first sealing portion 312 allows the first sealing element 31 to make sealing contact with the upper surface of the evaporator. The two sides of the first sealing portion 312 protrude from the two sides of the first sealing element body 311, which can expand the sealing coverage area, reduce gaps caused by assembly errors between the evaporator and the chamber 4 or slight axial movement during operation, and improve sealing redundancy.

[0057] In one embodiment, the second seal 32 includes a second seal body 321 and a second seal portion 322; one side of the second seal body 321 is radially recessed to form a second recess 325 for wrapping the lower part of the evaporator;

[0058] The second sealing part 322 is a flange formed by the second sealing body 321 extending outward along the circumferential contour of the second recess 325. Since the two sides of the second sealing part 322 protrude from the two sides of the second sealing body 321 respectively, the sealing coverage can be expanded, the gaps caused by assembly errors between the evaporator and the chamber 4 or slight axial movement during operation can be reduced, and the sealing redundancy can be improved.

[0059] The first recess 315 and the second recess 325 enclose a sealed mounting cavity 33. The rotating shaft of the evaporator 5 is rotatably mounted in the sealed mounting cavity 33, and the first sealing part 312 and the second sealing part 322 respectively contact the rotating shaft surface of the evaporator, thereby achieving the function of sealing the gap between the chamber 4 and the evaporator.

[0060] In one embodiment, the end faces of the first sealing member 31 located at both ends of the first recess 315 are the first contact surfaces 316, and the first contact surfaces 316 are used to contact the second sealing member 32.

[0061] The end faces of the second sealing member 32 located at both ends of the second recess 325 are the second contact surfaces 326, which are used to contact the first sealing member 31.

[0062] Both the first contact surface 316 and the second contact surface 326 are planar.

[0063] By making both the first contact surface 316 and the second contact surface 326 flat, it is beneficial to make the connection between the first seal 31 and the second seal 32 fit more tightly, thereby further improving the sealing effect.

[0064] In one embodiment, the cross-sectional shape of the first sealing part 312 and the second sealing part 322 is arc-shaped, which enables the first sealing part and the second sealing part to fit more closely to the surface of the evaporator and form a good sealing contact.

[0065] In one embodiment, both the first recess 315 and the second recess 325 are semi-circular. Since the evaporator's shaft is typically cylindrical, the semi-circular shape of the first and second recesses allows them to enclose a circular, sealed mounting cavity that matches the evaporator's shaft.

[0066] In one embodiment, the inner liner 1 has a first mounting portion 11 on both sides for mounting the first sealing member 31;

[0067] The first mounting portion 11 is provided with a first mounting groove 111 with an opening facing the evaporator. The shape and size of the first mounting groove 111 are adapted to the first sealing element body 311, and the first sealing element body 311 is detachably installed inside the first mounting groove 111. The shape and size of the first mounting groove 111 match the shape and size of the first sealing element body 311, so that the first sealing element body 311 can be installed precisely inside the first mounting groove 111.

[0068] The first sealing element body 311 is installed inside the first mounting groove 111, providing a stable mounting base for the first sealing element 31. This effectively limits its displacement during equipment operation, preventing positional shifts caused by evaporator rotation and other actions that could affect the sealing effect and enhance the stability of the sealing structure. Furthermore, since the first sealing element 31 protrudes from both sides of the first mounting portion 11, and the first sealing portion 312 is located outside the first mounting groove 111, it can better fit the evaporator cylinder, further preventing leakage from the gap between the chamber 4 and the evaporator. Moreover, during evaporator rotation, it first contacts the elastic first sealing element 31 rather than directly impacting the rigid first mounting portion 11, reducing impact wear during evaporator rotation, lowering equipment operating noise, and preventing damage to the first mounting portion 11 from direct impact, thus extending the equipment's service life and ensuring smooth evaporator rotation.

[0069] Furthermore, this structural design makes the disassembly and installation of the first seal 31 more targeted. The fit between the main body 311 of the first seal and the first mounting groove 111 facilitates quick positioning and operation. When replacing or cleaning the first seal 31, disassembly and assembly can be completed more easily, further reducing maintenance time and labor costs. At the same time, the first sealing part 312, protruding from the first mounting groove 111, has a better contact area and fit when forming a seal with the second seal 32. It can adapt to slight vibrations or displacements during equipment operation, ensuring sealing reliability during long-term use and reducing the risk of equipment failure due to sealing problems.

[0070] In one embodiment, the feeding mechanism 2 is provided with second mounting portions 21 on both sides for mounting the second sealing member 32;

[0071] The second mounting portion 21 is provided with a second mounting groove 211 with an opening facing the evaporator. The shape and size of the second mounting groove 211 are adapted to the second sealing element body 321, and the second sealing element body 321 is detachably installed inside the second mounting groove 211. The effect of this structural design is the same as that of the first sealing element 31 described above, so it will not be repeated here.

[0072] It is worth noting that after the feeding mechanism 2 and the inner liner 1 are both assembled into the shell of the cold drink equipment, the position of the second mounting part 21 corresponds to the position of the first mounting part 11, and the first mounting part and the second mounting part are in contact with each other so that the first sealing member 31 and the second sealing member 32 abut against each other; or the gap between the first mounting part 11 and the second mounting part 21 is very small, the first contact surface of the first sealing member 31 protrudes from the first mounting part 11, the second contact surface of the second sealing member 32 protrudes from the second mounting part 21, and the first contact surface 316 and the second contact surface 326 abut against each other, so that the first sealing member 31 and the second sealing member 32 are in close contact and form an annular sealing structure.

[0073] Preferably, the first contact surface 316 can protrude from the first mounting part 11, and the second contact surface 326 can also protrude from the second mounting part 21. After the feeding mechanism 2 and the inner liner 1 are both assembled into the shell of the cold drink equipment, by controlling the installation position of the feeding mechanism 2 and the inner liner 1, the first seal and the second seal can press against each other to form a tighter connection and a better sealing effect.

[0074] Specifically, a fixing groove (not shown in the figure) for installing the inner liner 1 can be provided inside the shell of the cold drink equipment. The inner liner 1 is inserted into the fixing groove, and a limiting rib or other structure can be provided on the outside of the inner liner 1 to ensure that the inner liner 1 can be firmly fixed in the fixing groove. The feeding mechanism 2 is installed below the evaporator and is installed in conjunction with the inner liner 1. By limiting the installation position of the feeding mechanism 2, the first mounting part 11 and the second mounting part 21 can be arranged opposite each other and the cooperation relationship between them can be controlled (such as contact or leaving a small gap).

[0075] Furthermore, one end of the feeding mechanism 2 is detachably installed on the inner liner 1, and the other end is detachably installed on the housing of the cold drink equipment. By controlling the installation position of the feeding mechanism 2, the first mounting part 11 and the second mounting part 21 can be brought into contact, and the first sealing member and the second sealing member can abut against each other.

[0076] In one embodiment, the first sealing member 31 further includes a plurality of first connecting members 313, one end of each of the plurality of first connecting members 313 being fixedly connected to the side of the first sealing member body 311 away from the first sealing part 312, and the other end being detachably connected to the first mounting part 11. The first sealing member 31 and the first mounting part 11 can be detachably connected through the first connecting members 313.

[0077] The first sealing element body 311 has a first positioning part 314 on each side, and the first mounting groove 111 has a first positioning groove 113 on each side that is adapted to the first positioning part 314. The first positioning part 314 is installed in the first positioning groove 113. The first positioning part 314 and the first positioning groove 113 are adapted to each other and are installed together, which makes the first sealing element 31 more securely installed, which is conducive to improving the sealing reliability and optimizing the performance of the sealing device in conjunction with other structures.

[0078] In one embodiment, the first connector 313 includes a first snap-fit ​​portion 3131, a first limiting portion 3132, and a first guide portion 3133 connected in sequence; the first snap-fit ​​portion 3131 and the first sealing body 311 are fixedly connected.

[0079] The first mounting part 11 is provided with a plurality of first snap-fit ​​holes 112, and the first snap-fit ​​holes 112 are connected to the first mounting groove 111;

[0080] The diameter and length of the first snap-fit ​​portion 3131 are adapted to the diameter and depth of the first snap-fit ​​hole 112, respectively. The diameter of the first limiting portion 3132 is larger than the diameter of the first snap-fit ​​hole 112, and the diameter of the first guide portion 3133 is smaller than the diameter of the first snap-fit ​​hole 112. The first limiting portion 3132 and the first guide portion 3133 pass through the first snap-fit ​​hole 112 and snap onto the outside of the first mounting portion 11. The diameter and length of the first snap-fit ​​portion 3131 are adapted to the first snap-fit ​​hole 112 to ensure a tight connection after insertion and prevent loosening. The small diameter of the first guide portion 3133 facilitates guiding the entire assembly through the first snap-fit ​​hole 112, improving installation smoothness. The large diameter of the first limiting portion 3132, after passing through the first snap-fit ​​hole 112, snaps onto the outside of the first mounting portion 11, providing a firm external limit to prevent the first seal 31 from falling off and enhancing installation stability. Because of the overall structural design of the first seal 31, the first seal 31 can be disassembled and installed without tools, which further simplifies the maintenance process and makes the disassembly and installation of the first seal 31 time-saving and labor-saving, while taking into account both the installation firmness and the ease of operation.

[0081] In one embodiment, the second sealing member 32 further includes a plurality of second connecting members 323, one end of each of the plurality of second connecting members 323 being fixedly connected to the side of the second sealing member body 321 away from the second sealing portion 322, and the other end being detachably connected to the second mounting portion 21. The second sealing member 322 and the second mounting portion 21 can be detachably connected through the second connecting members 323.

[0082] The second sealing element body 321 has second positioning posts 324 on both sides, and the second mounting groove 211 has second positioning grooves 213 on both sides that are adapted to the second positioning posts 324. The second positioning posts 324 are installed in the second positioning grooves 213. The cooperation between the second positioning posts 324 and the second positioning grooves 213 further defines the installation position of the second sealing element body 32, making the installation of the second sealing element body 32 more stable, which is conducive to improving the sealing reliability and optimizing the performance of the sealing device in conjunction with other structures.

[0083] In one embodiment, the second connector 323 includes a second snap-fit ​​portion 3231, a second limiting portion 3232, and a second guide portion 3233 connected in sequence; the second snap-fit ​​portion 3231 and the second sealing body 321 are fixedly connected.

[0084] The second mounting part 21 is provided with a plurality of second snap-fit ​​holes 212, and the second snap-fit ​​holes 212 are connected to the second mounting groove 211;

[0085] The diameter and length of the second snap-fit ​​portion 3231 are adapted to the diameter and depth of the second snap-fit ​​hole 212, respectively. The diameter of the second limiting portion 3232 is larger than the diameter of the second snap-fit ​​hole 212, and the diameter of the second guide portion 3223 is smaller than the diameter of the second snap-fit ​​hole 212. The second limiting portion 3232 and the second guide portion 3233 pass through the second snap-fit ​​hole 212 and snap onto the outside of the second mounting portion 21.

[0086] The diameter and length of the second snap-fit ​​portion 3231 are adapted to the second snap-fit ​​hole 212 to ensure a tight connection after insertion and prevent loosening. The small diameter of the second guide portion 3233 facilitates guiding the entire assembly through the second snap-fit ​​hole 212, improving installation smoothness.
