Abstract
Description
Technical Field
[0001] This utility model relates to the field of ice maker technology, and in particular to a connection mechanism between the evaporator and the refrigeration pipe of a snow ice machine. Background Technology
[0002] The evaporator of a shaved ice machine is used to create shaved ice flakes. During operation, liquid beverages or water are poured into the shaved ice machine and then directed onto the evaporator body. The evaporator instantly cools the water or liquid on its outer surface, thus forming edible shaved ice flakes.
[0003] Existing evaporators for shaved ice machines mainly consist of an evaporator cylinder that holds the refrigerant and detachable refrigeration pipes installed at one end of the evaporator cylinder. This design employs a sealed cylinder structure, with the refrigerant directly injected onto the inner wall of the evaporator cylinder, filling the entire cylinder cavity with refrigerant. This method effectively increases the refrigerant's contact area, resulting in a more efficient and direct cooling effect. Furthermore, the entire refrigeration and recovery cycle system requires only one cylinder structure and one shaft structure, simplifying the overall structure and making the manufacturing process easier.
[0004] However, the sealing structure at the connection between the evaporator and the refrigerant pipes in slush ice machines typically uses a conventional annular seal. In this structure, only a single annular contact surface is formed between the shaft and the seal. Since the evaporator cylinder of a slush ice machine rotates during operation, relying solely on a single annular contact surface for rotational sealing leads to accelerated wear of the seal. Simultaneously, poor contact at localized points can cause a decrease in overall sealing performance. Furthermore, if the seal is made of a hard material, wear will be further accelerated. With prolonged use, the seal will age, further reducing its sealing performance and increasing the risk of refrigerant leakage. Utility Model Content

[0006] This application provides a connection mechanism between the evaporator and the refrigeration pipe of a snow ice machine, which adopts the following technical solution:
[0007] A connection mechanism between an evaporator and a refrigeration pipe for a slush ice machine includes an evaporator connector and a refrigeration pipe connector rotatably installed within the evaporator connector. The evaporator connector has an installation channel for installing the refrigeration pipe connector. The refrigeration pipe connector is mounted on the evaporator connector by means of a mounting seat. A first sealing ring is provided between the evaporator connector and the mounting seat. A sealing assembly is installed within the installation channel. The circumferential surface of the refrigeration pipe connector is provided with an annular protrusion, which abuts against the end of the mounting seat.
[0008] By adopting the above technical solution, the refrigeration pipe connector is mounted on the evaporator connector by a mounting base, and a first sealing ring is provided between the evaporator connector and the mounting base, which can initially enhance the sealing performance of the connection. Specifically, the annular convex ring on the circumference of the refrigeration pipe connector abuts against the end of the mounting base, achieving axial positioning of the refrigeration pipe connector. Furthermore, a sealing component is installed within the mounting channel of the evaporator connector. Through the double sealing design of the first sealing ring and the sealing component within the mounting channel, the sealing performance between the evaporator and the refrigeration pipe of the slush ice machine is significantly improved.
[0009] Optionally, the sealing assembly includes a second sealing ring, a planar bearing sleeved on the refrigeration pipe joint, and sealing springs at both ends abutting against the planar bearing and the evaporator joint, respectively.

The plane bearing is sleeved on the refrigeration pipe joint and is always driven by the sealing spring to abut against the annular convex ring. It can ensure the sealing effect on both sides of the annular convex ring when the evaporator joint rotates. When the second sealing ring wears, the sealing spring will drive the plane bearing to continuously push the annular convex ring of the refrigeration pipe joint to abut tightly against the end of the mounting base, thereby continuing to maintain a good sealing effect at the connection.

[0012] By adopting the above technical solution, a first sealing ring is provided between the evaporator connector and the mounting base, and a first sealing ring groove is provided between one end of the mounting base and the mounting protrusion for the first sealing ring to be installed, which can limit the installation of the first sealing ring and improve the sealing performance of the connection between the evaporator connector and the mounting base.
[0013] Optionally, the inner wall of one end of the evaporator connector is provided with an internal thread, and the outer wall of the mounting base near the evaporator connector is provided with an external thread that mates with the internal thread.
[0014] By adopting the above technical solution, the evaporator connector and the mounting base are installed through the mating of internal and external threads, so that the refrigeration pipe connector can be more securely installed on the evaporator connector.
[0015] Optionally, the refrigeration pipe connector has a guide surface on the outer side wall of the installation channel for the planar bearing to be fitted.
[0016] By adopting the above technical solution, a guide surface is provided on the outer wall of the refrigeration pipe joint for the mounting of the planar bearing, which makes the installation of the planar bearing more stable, ensures the stable operation of the sealing assembly, and further guarantees the sealing performance.
[0017] Optionally, the mounting base has a first rotating groove on the outer periphery of the refrigeration pipe on the side opposite to the evaporator connector, and a first ball bearing is installed in the first rotating groove.
[0018] By adopting the above technical solution, a first rotating groove is opened on the outer periphery of the refrigeration pipe on the side of the mounting base away from the evaporator joint, and a first ball bearing is installed, which can reduce the friction force when the refrigeration pipe rotates and make the refrigeration pipe rotate more smoothly.
[0019] Optionally, a second rotating groove is provided on the outer side wall of the evaporator connector near the mounting base, and a second ball bearing is installed in the second rotating groove.
[0020] By adopting the above technical solution, a second rotating groove is opened on the outer side wall of the evaporator connector near the mounting base and a second ball bearing is installed, which can reduce the friction when the evaporator connector rotates and make the evaporator connector rotate more smoothly.
[0021] Optionally, the refrigeration pipe connector passes through the evaporator connector and extends into the evaporator cylinder.
[0022] By adopting the above technical solution, the refrigeration pipe connector passes through the evaporator connector and extends into the evaporator cylinder, further improving the sealing effect.
[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail below.
[0032] This application discloses a connection mechanism between the evaporator and the refrigeration pipe of a shaved ice machine. (Refer to...) Figure 1 and Figure 2 A connection mechanism between the evaporator and refrigeration pipe of a slush ice machine includes an evaporator connector 1 and a refrigeration pipe connector 2 rotatably installed within the evaporator connector 1. The evaporator connector 1 has an installation channel 11 for installing the refrigeration pipe connector 2, which passes through the evaporator connector 1 and extends into the evaporator cylinder. The refrigeration pipe connector 2 is positioned on the evaporator connector 1 by a mounting base 21. A first sealing ring 3 is provided between the evaporator connector 1 and the mounting base 21. One end of the mounting base 21 has a mounting protrusion 211, and a first sealing ring groove 22 for installing the first sealing ring 3 is provided between the end of the evaporator connector 1 near the mounting protrusion 211 and the mounting protrusion 211. The first sealing ring 3 initially enhances the sealing performance of the connection.
[0033] Reference Figure 2The annular protruding ring 23 on the circumference of the refrigeration pipe connector 2 abuts against the end of the mounting base 21, thereby limiting the axial movement of the refrigeration pipe connector 2. A sealing component 4 is installed within the mounting channel 11 of the evaporator connector 1. This dual sealing design of the first sealing ring 3 and the sealing component 4 within the mounting channel 11 significantly improves the sealing performance between the evaporator and the refrigeration pipe of the slush ice machine.
[0034] Reference Figure 2 and Figure 3 The sealing assembly 4 includes a second sealing ring 41, a planar bearing 42 fitted onto the refrigerant pipe connector 2, and sealing springs 43 whose two ends respectively abut against the planar bearing 42 and the evaporator connector 1. The second sealing ring 41 and the planar bearing 42 are located on opposite sides of the annular convex ring 23, and the sealing springs 43 drive the planar bearing 42 to always abut against the annular convex ring 23. The refrigerant pipe connector 2 has a guide surface 24 on its outer side wall within the mounting channel 11 for the planar bearing 42 to be fitted onto. The second sealing ring 41 further provides a sealing function. The planar bearing 42, fitted onto the refrigerant pipe connector 2 via the guide surface 24 and driven by the sealing springs 43 to always abut against the annular convex ring 23, ensures a sealing effect on both sides of the annular convex ring 23 when the evaporator connector 1 rotates. When the second sealing ring 41 wears, the sealing springs 43 drive the planar bearing 42, continuously pushing the annular convex ring 23 of the refrigerant pipe connector 2 tightly against the end of the mounting base 21, thereby maintaining a good sealing effect at the connection point.
[0035] Reference Figure 2 To facilitate the installation of the mounting base 21 on one end of the evaporator connector 1, the inner side wall of one end of the evaporator connector 1 is provided with an internal thread 12, and the outer side wall of the end of the mounting base 21 near the evaporator connector 1 is provided with an external thread 212 that mates with the internal thread 12. Through the engagement of the internal and external threads 212, the refrigerant pipe connector 2 can be more securely and firmly installed on the evaporator connector 1.
[0036] Reference Figure 2 The mounting base 21 has a first rotating groove 213 on the outer periphery of the refrigerant pipe on the side opposite to the evaporator connector 1, and a first ball bearing 2131 is installed in the first rotating groove 213. By opening the first rotating groove 213 on the outer periphery of the refrigerant pipe on the side of the mounting base 21 opposite to the evaporator connector 1 and installing the first ball bearing 2131, the friction force when the refrigerant pipe rotates can be reduced, making the refrigerant pipe rotate more smoothly.
[0037] Reference Figure 2A second rotating groove 13 is provided on the outer wall of the end of the evaporator connector 1 near the mounting base 21, and a second ball bearing 131 is installed in the second rotating groove 13. By providing a second rotating groove 13 and installing a second ball bearing 131 on the outer wall of the end of the evaporator connector 1 near the mounting base 21, the friction force when the evaporator connector 1 rotates can be reduced, making the rotation of the evaporator connector 1 smoother.
[0038] The implementation principle of the evaporator of the slush ice machine in this application embodiment is as follows: A connection mechanism between the evaporator and the refrigeration pipe of the slush ice machine includes an evaporator connector 1 and a refrigeration pipe connector 2 rotatably installed in the evaporator connector 1; the refrigeration pipe connector 2 is limited and installed on the evaporator connector 1 by a mounting base 21, and a first sealing ring 3 is provided between the evaporator connector 1 and the mounting base 21, which can initially enhance the sealing performance of the connection; the annular convex ring 23 on the circumference of the refrigeration pipe connector 2 abuts against the end of the mounting base 21, which can realize the axial limitation of the refrigeration pipe connector 2, and a sealing component 4 is installed in the installation channel 11 of the evaporator connector 1. Through the double sealing design of the first sealing ring 3 and the sealing component 4 in the installation channel 11, the sealing performance of the connection between the evaporator and the refrigeration pipe of the slush ice machine is significantly improved.
[0039] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application.
