[0042] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] Referring to Figures 1 and 2, an embodiment of the present invention provides a cold drink machine, including a chassis 1, a partition plate 2 disposed within the chassis 1, a cold drink device for forming cold drinks, and a compressor 3 for cooling the cold drink device. The partition plate 2 divides the chassis 1 into an upper device space and a lower device space, and the cold drink device and the compressor 3 are respectively disposed in the upper device space and the lower device space.

[0044] The cold drink device includes an evaporator 4, a cold drink tank 5 disposed in the evaporator 4, a stirring element 51 disposed in the cold drink tank 5, and a driving device 6 for driving the stirring element 51.

[0045] The front or top of the chassis 1 is provided with a display area, and the top of the chassis is provided with a feeding area;

[0046] In the display area, the front or top of the chassis 1 is inclined upward to form a display space 1a for installing display screen devices inside the chassis 1, and a display port 11a for installing a display panel is provided in the display area; this arrangement allows the display panel installed in the display port 11a to face the user's field of vision during operation, thereby facilitating operation and viewing of the display panel.

[0047] At the feeding area, the top of the casing 1 is recessed to form a feeding groove 1b, and a detachable feeding hopper 1c is provided in the feeding groove 1b. The feeding hopper 1c is connected to the cold drink tank 5.

[0048] Specifically, the upper equipment space is divided into a cooling space 1d and a driving heat dissipation space 1e on the left and right, and the evaporator 4 and the driving device 6 are respectively placed in the cooling space 1d and the driving heat dissipation space 1e.

[0049] On the casing 1, a discharge port 11 adapted to the cold drink tank 5 and an upper heat dissipation vent 12 for heat dissipation are respectively opened at the left and right ends of the upper equipment space. Preferably, the upper heat dissipation vent 12 is equipped with a heat dissipation plate 13, and the heat dissipation plate 13 has multiple heat dissipation channels.

[0050] In order to improve the structural compactness of the chassis 1 while ensuring a certain heat dissipation performance, the partition plate 2 is provided with a connecting area for connecting the upper device space and the lower device space, and the connecting area is provided with multiple connecting holes 21; the connecting area is correspondingly provided with the drive heat dissipation space 1e.

[0051] Furthermore, the lower equipment space is provided with a bracket 14 for auxiliary support of the partition substrate 2 and a heat exchange shell 15 for installing the heat exchanger on both sides; the bracket 14 and the heat exchange shell 15 together assist in supporting the partition substrate 2.

[0052] The compressor 3 is equipped with a heat exchanger 31 located inside the heat exchange housing 15. The heat exchange housing 15 is also equipped with a cooling fan 151 on its inner side, which is located below the communicating area. Correspondingly, the chassis 1 has a lower heat dissipation vent corresponding to the heat exchange housing 15, and the lower heat dissipation vent is also equipped with the heat dissipation plate 13.

[0053] Based on the configuration of the connecting hole 21, the cooling fan 151 located below the connecting area, during the process of exhausting heat to the lower heat dissipation port, causes air from the upper device space to flow into the lower device space and be discharged from the lower heat dissipation port. Therefore, the heat generated in the lower device space is difficult to flow into the upper device space, and due to the negative pressure, external air will flow into the drive heat dissipation space 1e from the upper heat dissipation port 12, thereby cooling the equipment installed in the drive heat dissipation space 1e. Therefore, the electronic control components can be installed in the drive heat dissipation space 1e. Thus, only a single and small-sized cooling fan 151 needs to be installed in the chassis 1 to dissipate heat from the upper and lower device spaces, thereby providing feasible conditions for the compact structural design and installation within the chassis 1.

[0054] To facilitate the disassembly of the feeding hopper 1c, the bottom of the feeding trough 1b is provided with a connecting pipe 11b that communicates with the cold drink can 5; the shape of the feeding hopper 1c is adapted to the feeding trough 1b to cover the surface of the feeding trough 1b.

[0055] The inner wall of the feed hopper 1c is provided with a lifting edge 11c for manual lifting, so as to remove the feed hopper 1c from the feed trough 1b.

[0056] Referring to Figures 3-8, the driving device 6 includes a rotating shaft 61 for driving the stirring element 51 to rotate and a first sealing connection seat 62.

[0057] The evaporator 4 is equipped with an insulating outer shell 41. The side wall of the insulating outer shell 41 has a first mounting hole 411. A cold drink can 5 is installed inside the insulating outer shell 41, and the cold drink can 5 has a second mounting hole 52. The rotating shaft 61 rotatably passes through the second mounting hole 52 and the first mounting hole 411. A first sealing connector 62 connects the insulating outer shell 41 and the cold drink can 5. The first sealing connector 62 is connected to a limiting member 621, which is inserted into the second mounting hole 52 and is sealed to the second mounting hole 52. The rotating shaft 61 passes through the limiting member 621. A first sealing member 63 is provided between the rotating shaft 61 and the limiting member 621. The inner ring of the first sealing member 63 is sealed to the rotating shaft 61, and the outer ring of the first sealing member 63 forms a clearance fit with the limiting member 621.

[0058] Since the outer ring of the first seal 63 and the limiting member 621 form a clearance fit, when the rotating shaft 61 rotates, the rotating shaft 61 can form a dynamic sealing connection between the first seal 63, the first sealing connection seat 62, and the limiting member 621. This reduces the amount of wear on the first seal 63 caused by the wear of the rotating shaft 61, extends the service life of the first seal 63, and ensures the sealing performance between the rotating shaft 61 and the first sealing connection seat 62. This effectively reduces the risk of liquid water leakage from the cold drink tank 5 and ensures the ice-making rate of the cold drink machine.

[0059] It should be noted that the first seal 63 is preferably made of wear-resistant and corrosion-resistant materials such as PTFE or rubber to ensure that the first seal 63 will not wear or corrode during long-term use.

[0060] In this embodiment, the first sealing connection seat 62 can be limited and assembled in the second mounting hole 52 of the cold drink can 5 by the limiting member 621, and the sealing performance between the first sealing connection seat 62 and the cold drink can 5 is guaranteed by the sealing connection between the limiting member 621 and the side wall of the second mounting hole 52.

[0061] To ensure a sealed fit between the limiting member 621 and the second mounting hole 52, as shown in Figures 3 to 5, an extended boss 622 is formed at one end of the limiting member 621 that is inserted into the second mounting hole 52. The outer ring of the extended boss 622 is sealed against the inner wall of the cold drink can 5 by a sealing gasket 623. The inner ring of the extended boss 622 is connected to the outer ring of the first sealing member 63, ensuring that the limiting member 621 limits and assembles the first sealing member 63 onto the rotating shaft 61. The sealing gasket 623 can deform under pressure, adaptively filling the gap between the connecting surfaces. This allows the sealing gasket 623 to adapt to the abutment gap between the extended boss 622 of the limiting member 621 and the inner wall of the cold drink can 5, achieving a sealed contact between the limiting member 621 and the inner wall of the cold drink can 5. This prevents liquid from leaking from the abutment position between the limiting member 621 and the inner wall of the cold drink can 5, further reducing the risk of liquid water leakage from the cold drink can 5.

[0062] Optionally, the limiting member 621 is made of elastic material such as rubber. When the limiting member 621 is inserted into the second mounting hole 52, the side wall of the limiting member 621 rebounds and tightly abuts against the side wall surface of the second mounting hole 52 to further enhance the sealing performance between the limiting member 621 and the cold drink can 5.

[0063] Of course, the limiting member 621 is not limited to elastic materials such as rubber, and can also be made of rigid materials. When the limiting member 621 is made of rigid material, the limiting member 621 and the first sealing connection seat 62 can be detachably connected to ensure the ease of assembly between the limiting member 621 and the first sealing connection seat 62.

[0064] Specifically, as shown in Figures 3 and 5, the limiting member 621 has a connecting post 611, and the connecting post 611 has multiple threaded holes arranged at intervals. The first sealing connecting seat 62 has multiple connecting holes. When the first sealing connecting seat 62 and the limiting member 621 are assembled into the cold drink can 5, the connecting post 611 of the limiting member 621 can be passed through the second mounting hole 52, and the first sealing connecting seat 62 and the limiting member 621 can be connected by bolts or studs, thereby ensuring the ease of assembly between the limiting member 621 and the first sealing connecting seat 62.

[0065] Furthermore, a second seal 64 is provided on the side of the first seal 63 away from the cold drink can 5. The inner ring of the second seal 64 is sealed to the rotating shaft 61, and the outer ring of the second seal 64 abuts against the limiting member 621. The second seal 64 is used to further reduce the connection gap between the limiting member 621 and the rotating shaft 61, thereby further enhancing the sealing performance between the rotating shaft 61 and the limiting member 621.

[0066] Specifically, the inner ring of the second seal 64 has a sealing lip surface with a beveled cross section, so that an oil seal is formed between the rotating shaft 61, the limiting member 621, and the first sealing connection seat 62 through the second seal 64, thereby using the second seal 64 in conjunction with the first seal 63 to provide stable and reliable sealing performance for the rotating shaft 61, the limiting member 621, and the first sealing connection seat 62.

[0067] In this embodiment, to ensure the installation stability of the first sealing connector 62, the first sealing connector 62 is formed at a preset height, and the distance between the inner side of the insulation shell 41 and the outer side of the cold drink can 5 is equal to the preset height. Therefore, when assembling the first sealing connector 62 between the insulation shell 41 and the cold drink can 5, the inner side of the insulation shell 41 and the outer wall of the cold drink can 5 can be used to clamp and fix the first sealing connector 62, and the limiting member 621 passing through the second mounting hole 52 can be used to connect the first sealing connector 62, ensuring the assembly stability of the first sealing connector 62 between the insulation shell 41 and the cold drink can 5, and preventing the first sealing connector 62 from shaking and affecting the sealing performance of the first sealing member 63.

[0068] In this embodiment, as shown in Figures 2 to 5, the driving device 6 further includes a second sealing connector 65. The second sealing connector 65 is disposed on the outer wall of the insulation shell 41. The second sealing connector 65 is detachably connected to the first sealing connector 62. The size of the second sealing connector 65 is larger than the size of the first mounting hole 411. Therefore, when the second sealing connector 65 is connected to the outer wall of the insulation shell 41, the second sealing connector 65 can block the first mounting hole 411, preventing the internal components of the insulation shell 41 from being exposed, thus achieving dust protection for the insulation shell 41.

[0069] It should be noted that, in order to detachably connect the first sealing connector 62 and the second sealing connector 65, the first sealing connector 62 and the second sealing connector 65 are connected to form an integral sealing device. The first sealing connector 62 has a connecting boss 625 on the side away from the cold drink can 5, and the second sealing connector 65 has a connecting hole. When assembling the first sealing connector 62 and the second sealing connector 65, the connecting boss 625 of the first sealing connector 62 passes through the mounting hole on the side wall of the heat preservation shell 41, and the first sealing connector 62 and the second sealing connector 65 are threaded together using bolts or studs.

[0070] Furthermore, as shown in Figures 3 to 5, a sealing boss 651 is formed on the side of the second sealing connector 65 facing the first sealing connector 62, and an insertion hole 624 is formed on the first sealing connector 62. The sealing boss 651 is inserted into the insertion hole 624, and the inner side of the sealing boss 651 abuts against the second sealing member 64. The sealing boss 651 and the second sealing member 64 are in sealing contact, thereby forming a sealing connection at the connection position of the first sealing connector 623 and the second sealing connector 65, and axially limiting the second sealing member 64, further ensuring the sealing performance of the second sealing member 64 on the first sealing connector 62 and the second sealing connector 65.

[0071] It should be noted that in this embodiment, the insertion hole 624 is coaxial with the first mounting hole 411 and the second mounting hole 52, the sealing boss 651 has a hollow hole, and the rotating shaft 61 is rotatably connected to the hollow hole so that the sealing boss 651 of the second sealing connection seat 65 can limit and protect the rotating shaft 61, thereby further ensuring the rotational stability of the rotating shaft 61.

[0072] As shown in Figure 6, the outer wall of the thermal insulation shell 41 has a first mounting groove 412, and the second sealing connector 65 is embedded in the first mounting groove 412. The first mounting groove 412 limits and fixes the outer wall of the second sealing connector 65, thereby further ensuring the stability of the second sealing connector 65 in the thermal insulation shell 41.

[0073] In an embodiment of the present invention, as shown in Figures 1 and 2, the driving device 6 further includes a driving connecting seat 66. One side of the driving connecting seat 66 is connected to a second sealing connecting seat 65, and the other side of the driving connecting seat 66 is connected to a driving member 7. A transmission assembly (not shown in the figures) is provided inside the driving connecting seat 66. The output shaft of the driving member 7 is rotatably connected to the driving end of the transmission assembly, and the driven end of the transmission assembly is rotatably connected to a rotating shaft 61. Thus, the driving member 7 can drive the driving end of the transmission assembly to rotate, thereby driving the driven end of the transmission assembly and the rotating shaft 61 to rotate. This allows the rotating shaft 61 to drive the stirring structure inside the cold drink can 5 to rotate, realizing the transfer of ice cubes inside the cold drink can 5.

[0074] By using the drive connector 66 to provide dust protection for the transmission assembly and the connection between the transmission assembly and the drive component 7 and the rotating shaft 61, the drive component 7, the transmission assembly and the rotating shaft 61 can be prevented from being directly exposed to the external environment, ensuring effective transmission between the drive component 7, the transmission assembly and the rotating shaft 61, and ensuring the energy utilization rate of the drive component 7.

[0075] It should be noted that the drive connector 66 may include a detachably connected first connector and a second connector to facilitate maintenance and repair of the transmission assembly inside the drive connector 66. The first connector is connected to the housing of the drive motor, and the second connector is connected to the second sealed connector 65. The front end of the rotating shaft 61 is rotatably connected to the second connector via a bearing to further ensure the rotational stability of the rotating shaft 61.

[0076] It should also be noted that the transmission group preferably uses a gear set to drive the drive component 7 and the rotating shaft 61, in order to reduce the space occupied by the drive connecting seat 66 and improve the space utilization rate of the sealing connection components of the material housing. Of course, the specific structure of the transmission group is not limited to a gear set, and can also be other transmission structures such as chain drive or belt drive. The specific transmission structure of the transmission group can be set according to the actual situation.

[0077] As shown in Figure 2, a second mounting groove 652 is formed on the side of the second sealing connector 65 away from the heat insulation shell 41. One side of the drive connector 66 is embedded in the second mounting groove 652 to limit and fix the side of the second sealing connector 65 through the second mounting groove 652, so as to ensure the connection stability between the second sealing connector 65 and the drive connector 66.

[0078] It should be noted that, in order to further ensure the connection stability between the drive connector 66 and the second sealing connector 65, multiple threaded countersunk holes are formed in the second mounting groove 651, and multiple threaded holes are formed in the drive connector 66. When one side of the drive connector 66 is fitted into the second mounting groove 652, it is spirally connected to the corresponding threaded holes and threaded countersunk holes by bolts or studs, so as to further improve the connection stability between the drive connector 66 and the second sealing connector 65.

[0079] Furthermore, in order to increase the material buffer capacity of the feed trough 1b, the opening of the feed trough 1b extends upward by a predetermined length to form a guide channel housing communicating with the feed trough 1b. The guide channel housing has a tubular structure. The guide channel housing is provided with a cover to cover the upper port of the guide channel housing.

[0080] The cold drink machine is an ice cream machine, a smoothie machine, or a multi-functional ice cream and smoothie maker, which can be used to make ice cream and smoothies.

[0081] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
