[0037] Furthermore, the snow melter is used to make ice cubes, slush or keep specific foods at low temperatures. By setting up a temperature sensing component 5, the temperature inside the refrigeration system or the surrounding environment can be monitored in real time, which helps to ensure that the system can accurately control the temperature within a preset range.

[0038] Furthermore, the third sealing member 6 effectively isolates the gap between the temperature sensing component 5 and the refrigeration barrel shell 1 , thereby preventing external liquid from entering the interior of the refrigeration barrel shell 1 through the gap between the temperature sensing component 5 and the refrigeration barrel shell 1 .

[0042] Furthermore, the third sealing member 6 is a silicone sealing ring.

[0043] like Figures 1 to 8 The first connecting mechanism 4 shown includes a mounting base 41 located on one side of the inner wall of the refrigeration barrel shell 1 and a mounting cover 42 located on one side of the outer wall of the refrigeration barrel shell 1. The mounting base 41 and the mounting cover 42 are connected so that the first seal 31 and the second seal 32 are fixed between the mounting base 41 and the mounting cover 42.

[0044] Optionally, in some embodiments, the mounting base 41 and the mounting cover 42 may be connected by a snap-fit connection.

[0045] Optionally, in some embodiments, the mounting base 41 and the mounting cover 42 may be connected by a lock connection.

[0046] Optionally, in some embodiments, the mounting base 41 and the mounting cover 42 may be connected by a slot connection.

[0047] Optionally, in some embodiments, the mounting base 41 and the mounting cover 42 are integrally formed.

[0048] Furthermore, as a preferred embodiment of the present invention but not a limitation thereof, the mounting base 41 and the mounting cover 42 are threadedly connected.

[0049] Furthermore, by combining the mounting base 41 and the mounting cover 42 , the first sealing member 31 and the second sealing member 32 can be securely disposed between the rotating shaft 2 and the refrigeration barrel shell 1 , thereby ensuring a good sealing effect.

[0050] Furthermore, through the cooperation of the mounting base 41 and the mounting cover 42, a more reliable sealing effect can be achieved, and a multi-level fixing arrangement is provided to further enhance the sealing performance between the first seal 31 and the second seal 32.

[0051] Optionally, in some embodiments, the mounting base 41 and the mounting cover 42 are made of stainless steel.

[0052] Optionally, in some embodiments, the mounting base 41 and the mounting cover 42 are made of aluminum alloy.

[0053] Furthermore, as a preferred embodiment of the present invention rather than a limitation, the mounting base 41 and the mounting cover 42 are made of plastic.

[0054] Optionally, in some embodiments, the rotating shaft 2 penetrates through the refrigeration barrel housing 1. The cross-section of the first seal 31 is in the shape of a "king" character. The first seal 31 is provided with a first seal groove and a second seal groove. The first seal groove is engaged with the boss 421, and the second seal groove is engaged with the refrigeration barrel housing 1. The cross-section of the second seal 32 is in the shape of a "worker" character, and the second seal 32 is engaged with the refrigeration barrel housing 1.

[0055] Optionally, in some embodiments, both the first seal 31 and the second seal 32 are located near the outer wall of the refrigeration barrel housing 1. The cross-section of the first seal 31 is in the shape of a "worker" character, and the cross-section of the second seal 32 is circular.

[0056] As Figures 1 to 8 shown, a boss 421 extending in the direction of the mounting base 41 is provided on the side of the mounting cover 42 away from the mounting base 41. A first groove 311 engaged with the boss 421 is provided on the first seal 31, so that the first seal 31 and the mounting cover 42 are detachably connected;

[0057] Furthermore, the engagement setting of the boss 421 and the first groove 311 can ensure a stable connection between the first seal 31 and the mounting cover 42, thus maintaining a good sealing effect. Secondly, the engagement setting is beneficial to reducing the possibility of the first seal 31 moving due to vibration or pressure change during operation, and effectively maintaining a stable sealing performance.

[0058] Furthermore, the detachably connected setting makes the installation and replacement of the first seal 31 simple and fast. When the user needs to maintain or replace the first seal 31, the first seal 31 can be easily removed and a new seal can be installed by simply releasing the engagement, which is beneficial to reducing the maintenance cost and difficulty.

[0059] Furthermore, the first seal 31 and the mounting cover 42 are interference fit, and the interference fit causes the first seal 31 to be compressed during the installation process, thereby forming a tight fit between the first seal 31 and the mounting cover 42, which helps to reduce or eliminate leakage channels, thereby significantly improving the sealing performance.

[0060] Furthermore, the cross section of the first sealing member 31 is in the shape of an I.

[0061] Optionally, in some embodiments, the user can utilize the elastic properties of the first sealing member 31 to install the first sealing member 31 from the outer side wall of the installation cover 42 toward the inner side wall of the installation cover 42 .

[0062] Optionally, in some embodiments, the user can utilize the elastic properties of the first sealing member 31 to install the first sealing member 31 from the inner side wall of the installation cover 42 toward the outer side wall of the installation cover 42 .

[0063] like Figures 1 to 8 The mounting cover 42 shown is provided with a second groove 422 for accommodating the second sealing member 32 on a side close to the refrigeration barrel housing 1, and a first connecting cylinder 423 extending through the second sealing member 32 and toward the mounting base 41. The mounting base 41 is provided with a first connecting groove 411 that is threadedly connected to the first connecting cylinder 423, so that the second sealing member 32 is fixed to the outer wall of the refrigeration barrel housing 1;

[0064] Furthermore, the second seal 32 is placed in the second groove 422 and is threadedly connected to the first connecting groove 411 through the first connecting cylinder 423, thereby effectively fixing the second seal 32, which is conducive to ensuring that the second seal 32 fits tightly on the outer wall of the refrigeration barrel shell 1, effectively preventing external liquid from entering the interior of the refrigeration barrel shell 1, and helping to maintain the sealing of the equipment.

[0065] Furthermore, threaded connection is a very stable connection method. Through the close fit between the first connecting cylinder 423 and the first connecting groove 411, it is helpful to enhance the connection strength between the mounting cover 42 and the mounting base 41, help to resist external pressure and vibration, and effectively ensure the stable operation of the entire assembly.

[0066] Furthermore, the second groove 422 provides a stable accommodation space for the second sealing member 32 , effectively preventing the second sealing member 32 from moving or misaligning during the installation process, thereby ensuring the durability and stability of the sealing effect.

[0067] like Figures 1 to 8The mounting base 41 is provided with a third groove 412 and an oil seal ring 413 located in the third groove 412 and sleeved on the outer wall of the rotating shaft 2. The third groove 412 is provided with a supporting portion 414 for supporting the oil seal ring 413.

[0068] Furthermore, the supporting portion 414 on the third groove 412 provides stable support and positioning for the oil seal ring 413, so that the oil seal ring 413 can be easily aligned and fixed in place during the installation process, which is conducive to simplifying the installation process and effectively improving the installation efficiency; secondly, when the oil seal ring 413 is worn or fails, the user can easily replace the oil seal ring 413 with a new one by removing the oil seal ring 413 on the mounting base 41, thereby ensuring the stable operation of the system.

[0069] Optionally, in some embodiments, the supporting portion 414 is a supporting boss.

[0070] Furthermore, as a preferred embodiment of the present invention but not a limitation, the supporting portion 414 is provided with a plurality of supporting pillars spaced apart along the circumferential direction of the third groove 412. The plurality of supporting pillars can evenly disperse the pressure on the oil seal ring 413, which is beneficial to avoid concentrated stress and effectively reduce the burden on each supporting pillar.

[0071] Furthermore, the oil seal ring 413 is sleeved on the outer wall of the rotating shaft 2 and is located in the third groove 412, which can effectively prevent lubricating oil or other working media from leaking from the gap between the rotating shaft 2 and the mounting base 41. The oil seal ring 413 can fit tightly to the surface of the rotating shaft 2 to form a reliable sealing barrier; secondly, the oil seal ring 413 not only prevents leakage of the medium, but also reduces direct contact and friction between the rotating shaft 2 and the mounting base 41, thereby reducing the degree of wear, which is conducive to extending the service life of the rotating shaft 2 and the mounting base 41.

[0072] Furthermore, the oil seal ring 413 is interference fit with the rotating shaft 2 .

[0073] like Figures 1 to 8 The oil seal ring 413 is provided with a sealing flap 4131, and the sealing flap 4131 is extended obliquely from the outside to the inside toward the mounting cover 42;

[0074] Furthermore, the obliquely arranged sealing petals 4131 can better fit the surface of the rotating shaft 2, thereby improving the sealing performance.

[0075] Furthermore, the inclined sealing petal 4131 can reduce the friction between the contact surface of the sealing ring 413 and the rotating shaft 2, which is beneficial to reducing wear, helps to evenly distribute the contact pressure, and effectively reduces the degradation of sealing performance caused by wear.

[0076] Furthermore, the tilted sealing flap 4131 can effectively prevent oil from escaping from the sealing contact surface, thereby providing more reliable sealing performance.

[0077] like Figures 1 to 8 The temperature sensing assembly 5 shown includes a temperature sensing probe 51 and a connecting portion 52 connected to the temperature sensing probe 51. The third sealing member 6 is sleeved on the outer wall of the connecting portion 52. The second connecting mechanism 7 includes a heat-insulating nut 71. The heat-insulating nut 71 is threadedly engaged with the connecting portion 52 to fix the third sealing member 6 between the temperature sensing assembly 5 and the refrigeration barrel shell 1.

[0078] Furthermore, by sleeved on the outer wall of the connecting portion 52, the third sealing member 6 can effectively prevent external liquid from entering the interior of the refrigeration barrel shell 1 from the gap between the temperature sensing component 5 and the refrigeration barrel shell 1, thereby effectively ensuring the airtightness of the system and improving the overall working efficiency and safety of the device.

[0079] Furthermore, the threaded cooperation between the heat-insulating nut 71 and the connecting portion 52 not only achieves a stable installation of the temperature sensing component 5 , but also enhances the sealing effect between the temperature sensing component 5 and the refrigeration barrel shell 1 by compressing the third sealing member 6 .

[0080] Furthermore, the temperature sensor 51 can accurately monitor the temperature around the evaporator, provide reliable data support for the temperature control of the system, help ensure that the refrigeration system always operates in the best condition, and help improve the stability and reliability of the refrigeration system.

[0081] Furthermore, as a preferred embodiment of the present invention but not a limitation thereof, the heat-insulating nut 71 is made of plastic material.

[0082] Specifically, the third sealing member 6 is made of silicone material, which can effectively prevent external liquid from entering the interior of the refrigeration barrel shell 1 from the gap between the temperature sensing component 5 and the refrigeration barrel shell 1. At the same time, the heat-insulating nut 71 is made of plastic material, which further improves the airtightness between the refrigeration barrel shell 1 and the temperature sensing component 5. The sealing cooperation between the third sealing member 6 and the temperature sensing component 5 is conducive to achieving a double sealing effect, effectively improving the overall working efficiency and safety of the device; secondly, silicone material and plastic material are both heat-insulating materials, the temperature sensing component 5 includes a temperature sensing probe 51 and a connecting part 52, and the third sealing member 6 includes a first sealing part 61 and a second sealing part 62. The first sealing part 61 is located at the temperature sensing probe 51 and the connecting part 52. The probe 51 is effectively isolated from the outer wall of the refrigeration barrel shell 1 by the temperature sensing probe 51. The second sealing portion 62 is located on the outer side wall of the connecting portion 52, effectively isolating the connecting portion 52 from the inner wall of the refrigeration barrel shell 1. The heat-insulating nut 71 is threadedly engaged with the connecting portion 52 so that the third sealing member 6 is fixed between the temperature sensing component 5 and the refrigeration barrel shell 1. At the same time, the third sealing member 6 and the heat-insulating nut 71 cooperate to prevent the temperature sensing component 5 from contacting the refrigeration barrel shell 1. The heat-insulating performance of the third sealing member 6 and the heat-insulating nut 71 effectively prevents the heat on the refrigeration barrel shell 1 from being directly transferred to the temperature sensing component 5, thereby improving the accuracy of temperature measurement of the temperature sensing component 5.

[0083] like Figures 1 to 8 The third sealing member 6 shown includes a first sealing portion 61 and a second sealing portion 62 connected to the first sealing portion 61 . The outer walls of the first sealing portion 61 and the second sealing portion 62 are both provided with sealing threads.

[0084] Furthermore, the first sealing portion 61 and the second sealing portion 62 are vertically connected, and the cross-section of the third sealing member 6 is T-shaped. The temperature of the refrigeration barrel shell 1 is relatively low. When the temperature sensing component 5 contacts the refrigeration barrel shell 1, the lower temperature of the refrigeration barrel shell 1 is transmitted to the temperature sensing component 5, so that the temperature detected by the temperature sensing component 5 is inaccurate. The first sealing portion 61 is located between the temperature sensing probe 51 and the outer wall of the refrigeration barrel shell 1, effectively isolating the contact between the temperature sensing probe 51 and the outer wall of the refrigeration barrel shell 1. The second sealing portion 62 is located on the outer side wall of the connecting portion 52, effectively isolating the contact between the connecting portion 52 and the inner wall of the refrigeration barrel shell 1. The third sealing member 6 effectively isolates the contact between the temperature sensing component 5 and the refrigeration barrel shell 1, thereby preventing the temperature sensing component 5 from being affected by the lower temperature of the refrigeration barrel shell 1, resulting in inaccurate temperature detection.

[0085] Furthermore, the setting of the sealing thread enables the third seal 6 to fit more tightly between the temperature sensing component 5 and the refrigeration barrel shell 1 during the assembly process, thereby effectively preventing external liquid from entering the interior of the refrigeration barrel shell 1. The setting of the sealing thread is conducive to increasing the contact area and the tightness of the seal.

[0086] like Figures 1 to 8 The snow melt machine shown includes a body 8, which includes the evaporator as described above;

[0087] Specifically, as the core component of the snow melt machine refrigeration system, the evaporator needs to have high cooling and sealing properties. The front end of the refrigeration barrel shell 1 is provided with a rotating shaft 2 that passes through the refrigeration barrel shell 1. The first connecting mechanism 4 is provided to fix the first seal 31 and the second seal 32 between the refrigeration barrel shell 1 and the rotating shaft 2, effectively preventing external liquid from entering the interior of the refrigeration barrel shell 1; secondly, the refrigeration barrel shell 1 is provided with a temperature sensing component 5 that passes through the refrigeration barrel shell 1 and is used to detect the temperature. The setting of the temperature sensing component 5 is conducive to ensuring that the device operates within a suitable temperature range. When the temperature of the refrigeration barrel shell 1 is low, When the temperature sensing component 5 contacts the refrigeration barrel shell 1, the lower temperature of the refrigeration barrel shell 1 is transferred to the temperature sensing component 5, so that the temperature detected by the temperature sensing component 5 is inaccurate. By providing the third seal 6 and the insulation nut 71, it is possible to effectively prevent external liquid from entering the interior of the refrigeration barrel shell 1 from the gap between the temperature sensing component 5 and the refrigeration barrel shell 1. At the same time, the temperature sensing component 5 will not contact the refrigeration barrel shell 1. The thermal insulation performance of the third seal 6 and the insulation nut 71 effectively prevents the heat on the refrigeration barrel shell 1 from being directly transferred to the temperature sensing component 5, thereby improving the accuracy of temperature measurement of the temperature sensing component 5.

[0088] The implementation of this embodiment is as follows:

[0089] A sealing structure for an evaporator includes a refrigeration barrel shell 1, a rotating shaft 2 passing through the refrigeration barrel shell 1, and a temperature sensing component 5 passing through the refrigeration barrel shell 1. A first seal 31, a second seal 32, and a first connecting mechanism 4 are provided between the rotating shaft 2 and the refrigeration barrel shell 1. A third seal 6 and a second connecting mechanism 7 are provided between the temperature sensing component 5 and the refrigeration barrel shell 1. The first connecting mechanism 4 includes a mounting base 41 located on one side of the inner wall of the refrigeration barrel shell 1 and a mounting cover 42 located on one side of the outer wall of the refrigeration barrel shell 1. The mounting cover 42 is provided with a boss 421. The first seal 31 is provided with a first groove 311 that is engaged with the boss 421, so that the first seal 31 and the mounting cover 42 are detachable. The second sealing member 32 is fixed to the outer wall of the refrigeration barrel shell 1. The combination of the first sealing member 31 and the second sealing member 32 provides double protection. Even if one layer of the sealing member fails for some reason, such as wear, aging or improper installation, the other layer of sealing member can still maintain the sealing effect, significantly reducing the risk of external liquid penetrating into the evaporator. It effectively solves the problem that the evaporator in the existing snow melting machine often adopts a single-layer sealing structure. When the sealing ring is not installed in place or the sealing ring is damaged, the external liquid will penetrate into the evaporator and affect the normal operation of the device. The temperature sensing component 5 includes a temperature sensing probe 51 and a connecting portion 52 connected to the temperature sensing probe 51. The third sealing member 6 is sleeved on the outer wall of the connecting portion 52. The second connecting mechanism 7 includes an insulating nut 71. The insulating nut 71 is threadedly engaged with the connecting portion 52 so that the third sealing member 6 is fixed between the temperature sensing component 5 and the refrigeration barrel shell 1. The temperature of the refrigeration barrel shell 1 is relatively low. When the temperature sensing component 5 contacts the refrigeration barrel shell 1, the lower temperature of the refrigeration barrel shell 1 is transferred to the temperature sensing component 5, so that the temperature detected by the temperature sensing component 5 is inaccurate. By providing the third sealing member 6 and the insulating nut 71, it is possible to effectively prevent external liquid from entering the interior of the refrigeration barrel shell 1 through the gap between the temperature sensing component 5 and the refrigeration barrel shell 1. At the same time, the temperature sensing component 5 will not contact the refrigeration barrel shell 1. The thermal insulation performance of the third sealing member 6 and the insulating nut 71 effectively prevents the heat on the refrigeration barrel shell 1 from being directly transferred to the temperature sensing component 5, thereby improving the accuracy of temperature measurement of the temperature sensing component 5.
