[0041] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0042] The cold drink machine of this invention can effectively improve the ease of operation of the cold drink machine, reduce the user's operation actions and steps, and enhance the user's experience of using the cold drink machine.

[0043] In one specific embodiment of this utility model, such as Figures 1 to 4 As shown, the cold drink machine includes a casing 1. Inside the casing 1, a cooling system 2 and a feeding system 3 are arranged. The cooling system 2 is connected to the feeding system 3 to provide cooling for the feeding system 3. The casing 1 has a feeding trough 11, and the outlet of the feeding trough 11 is sealed to the inlet of the feeding system 3.

[0044] The top plate of the housing 1 is provided with a feed cover 12, which rotates to close onto the feed chute 11. A mounting base 13 is provided on the top and / or front of the housing 1. The top surface of the mounting base 13 slopes downwards towards the front side plate of the housing 1. A mounting groove 131 is formed on the top surface of the mounting base 13, and a control panel 14 is disposed in the mounting groove 131. The control panel 14 is electrically connected to the material preparation system 3 and the cooling system 2. The feed cover 12 is located on the side of the mounting base 13 opposite to the front side plate of the housing 1.

[0045] According to this embodiment of the cold drink machine, by rotating the feed cover 12 to cover the feed trough 11, the opening and closing operations of the cold drink machine are more convenient. When the user needs to open the cold drink machine, he / she only needs to pry the feed cover 12 upwards, without having to perform any additional actions to place the feed cover 12.

[0046] The user can then operate the various function buttons on the control panel 14 to control the cooling system 2 and the ingredient preparation system 3 inside the beverage machine. Since the top surface of the mounting base 13 is tilted downwards towards the front panel of the casing 1, the control panel 14 can be tilted and installed on the top panel of the casing 1, allowing the user to maintain a natural posture and comfort when operating the control panel 14 without having to bend over excessively. Furthermore, since the feed cover 12 is located on the side of the mounting base 13 away from the front panel of the casing 1, that is, the control panel 14 is located in front of the feed position of the beverage machine, the user can directly add ice-making ingredients to the feed trough 11 and the ingredient preparation system 3 in front of the beverage machine, and then directly switch to the control panel 14 to select the corresponding function of the beverage machine.

[0047] Therefore, the beverage cooler provided in this embodiment, by rotating the feed cover 12 to cover the feed trough 11 and tilting the control panel 14 to install it on the top plate of the beverage cooler, and setting the feed cover 12 on the side of the mounting base 13 away from the front side plate of the casing 1, can effectively improve the ease of operation of the beverage cooler. When using the beverage cooler, the user only needs to rotate the feed cover 12 in front of the beverage cooler to open it and feed the slurry into the feed trough 11. Then, the user can operate the function buttons of the control panel 14 in a natural and comfortable posture to control the operation of the beverage cooler. This effectively reduces the user's operation actions and steps for the beverage cooler and enhances the user's experience of using the beverage cooler.

[0048] It should be noted that the housing 1 includes a front panel, a left panel, a rear panel, and a right panel that are detachably connected in sequence. A top panel is detachably connected to the top of each side panel, and a bottom panel is detachably connected to the bottom of each side panel. This simplifies the installation structure of the housing 1 and improves the assembly and maintenance efficiency of the housing 1. The left, right, and rear panels are all equipped with ventilation holes, while the front panel has a flat surface. This ensures that the distribution of ventilation holes meets the actual heat dissipation needs of the beverage dispensing system 3 and the cooling system 2 within the beverage machine, while avoiding any impact on users located in front of the beverage machine during heat dissipation, further guaranteeing the user's experience with the beverage machine.

[0049] Preferably, the mounting base 13 is disposed on the top plate, and the front side plate has a cover surface that covers the top of the mounting base to fix the control panel to the cold drink machine housing.

[0050] Specifically, to facilitate users in opening the feed cover 12 of the cold drink machine, such as Figures 4 to 6 As shown, the top plate of the housing 1 has a connecting seat 121, which surrounds the feeding groove 11. One edge of the feeding cover 12 has a flip shaft 122, which is rotatably connected to the connecting seat 121. The flip shaft 122 makes it easier to open or close the feeding cover 12 and ensures that the feeding cover 12 has a stable installation position on the top plate, preventing the feeding cover 12 from accidentally falling into the beverage machine during opening.

[0051] The other edges of the feed cover 12 are formed with handles 123. The handles 123 protrude outward from the feed cover 12, and a gripping gap is formed between the bottom of the handles 123 and the top plate of the housing 1. The gripping gap between the handles 123 and the top plate of the housing 1 provides a point of leverage for the user. When opening the feed cover 12, the user only needs to hold the handles 123 from the gripping gap and pry the feed cover 12 upward to open the feed cover 12, thereby further improving the ease of operation of the cold drink machine.

[0052] It should be noted that, in order to further ensure the stability of the feed cover 12 during the flipping process, the two ends of the flipping shaft 122 are provided with outwardly extending convex dots, and two connecting seats 121 are formed on the top plate of the housing 1. The two connecting seats 121 are respectively provided with rotating holes corresponding to the convex dots. The convex dots are adapted to the rotating holes to reduce the sliding of the feed cover 12 during the flipping process and improve the stability and durability of the feed cover 12 flipping structure.

[0053] An avoidance concave arc is formed on the top plate of the housing 1. The avoidance concave arc is located below the flip shaft 122 to avoid obstruction when the flip shaft 122 rotates.

[0054] Furthermore, such as Figures 4 to 6 As shown, the top plate of the housing 1 is provided with a feeding platform, and a connecting seat 121 is formed on the feeding platform. A groove is formed along the edge of the feeding platform, and two edges of the feeding cover 12 are provided with engaging portions 124, which engage with the groove. Through the cooperation of the engaging portions 124 and the groove, the feeding cover 12 can maintain a stable connection when closed on the top plate of the housing 1, preventing the feeding cover 12 from loosening and opening, thus avoiding slurry splashing, and preventing foreign objects from falling into the feeding trough 11, affecting hygiene and safety.

[0055] In this embodiment, as Figure 4 , Figure 5 and Figure 7 As shown, a feeding hopper 16 is arranged inside the feeding trough 11. The outlet end of the feeding hopper 16 is inserted into the inlet of the material preparation system 3. The outlet of the feeding trough 11 is surrounded outside the inlet of the material preparation system 3. The outlet of the feeding trough 11 and the outside of the inlet of the material preparation system 3 are tightly abutted by a connecting seal 161, thereby ensuring the sealing of the connection between the feeding trough 11, the feeding hopper 16 and the material preparation system 3. This ensures that when the slurry is fed into the material preparation system 3 from the feeding hopper 16, it will not leak from the feeding hopper 16 or the connection between the feeding trough 11 and the material preparation system 3, thus ensuring the operational safety of the internal system of the cold drink machine.

[0056] It should be noted that the feed hopper 16 is detachably connected to the feed trough 11, which makes it easy to remove the feed hopper 16 from the feed trough 11 so as to clean the parts of the feed trough 11 that come into contact with the slurry regularly, and to prevent the slurry from remaining in the feed trough 11 and causing bacterial contamination.

[0057] To ensure the installation stability of the connecting seal 161, the outer wall of the feed inlet of the material preparation system 3 has an outwardly extending insertion part, which is embedded in the connecting seal 161 and abuts tightly against it. The discharge outlet of the feed trough 11 forms an abutment surface 111, which abuts tightly against the side of the connecting seal 161 away from the insertion part. At the same time, the side of the connecting seal 161 forms a threaded contact surface 165, which abuts tightly against the inner wall of the discharge outlet section of the feed trough 11, thereby ensuring the sealing performance between the feed trough 11 and the feed inlet of the material preparation system 3.

[0058] The connecting seal 161 is preferably made of elastic sealing material such as rubber or silicone.

[0059] It should be noted that, in order to ensure that the feed hopper 16 is stably installed in the feed trough 11, the top edge of the feed trough 11 forms an overlapping surface, and the outer wall surface of the feed hopper 16 forms a receiving surface that matches the overlapping surface, so that the feed hopper 16 can be overlapped and placed in the feed trough 11 by using the cooperation of the receiving surface and the overlapping surface.

[0060] A handle protrusion 164 is formed on the inner edge of the top of the feed hopper 16. The handle protrusion 164 extends into the feed hopper 16. In actual use, the user can grab the handle protrusion 164 to remove the feed hopper 16 from the feed trough 11 for cleaning.

[0061] In this embodiment, as Figure 1 , Figure 2 and Figure 8 As shown, a cover portion 17 is formed on the top of the front panel of the housing 1. The cover portion 17 is engaged with the mounting groove 131, and the tilt angle of the cover portion 17 is the same as the tilt angle of the top surface of the mounting base 13. The tilt angles of the cover portion 17 and the top surface of the mounting base 13 can be determined according to actual conditions to ensure that the tilt angle of the control panel 14 conforms to the user's observation habits and that the user can maintain a natural posture and comfort when observing and operating the control panel 14.

[0062] To ensure the stability of the control panel 14 installation, such as Figure 8 As shown, the cover portion 17 forms a mounting frame 171, and the inner wall of the mounting frame 171 is provided with a plurality of spaced-apart stop protrusions 172. The edge of the control panel 14 is formed with a snap-fit ​​hole 141 that matches the stop protrusion 172, so that the control panel 14 can be installed on the mounting frame 171 by snap-fit, ensuring the installation stability of the control panel 14, while reducing the difficulty of disassembling and assembling the control panel 14 and improving the maintenance and replacement efficiency of the control panel 14.

[0063] In embodiments of this utility model, such as Figure 3 , Figures 9 to 13As shown, the feeding system 3 includes a drive unit 31, an insulation shell 32, a feeding cylinder 33, a stirring element 34, and an evaporator pipe 35. The feeding cylinder 33 is installed inside the insulation shell 32. The stirring element 34 is rotatably arranged inside the feeding cylinder 33. The output shaft of the drive unit 31 is connected to the stirring element 34. The evaporator pipe 35 is wound around the outer wall of the feeding cylinder 33 and is connected to the cooling system 2. A feed pipe 36 is formed on the side wall of the feeding cylinder 33. The feed pipe 36 extends out of the insulation shell 32, and the outer wall of the inlet section of the feed pipe 36 is sealed to the inner wall of the outlet end of the feed trough 11. The discharge port of the feeding cylinder 33 is located on the front side plate of the casing 1.

[0064] Understandably, when the ice-making slurry is fed into the ice-making cylinder 33 through the feed trough 11 and feed pipe 36, the user can control the cooling system 2 to start via the control panel 14. This allows the cooling system 2 to operate and deliver the condensed refrigerant to the evaporator pipe 35, enabling the ice-making slurry in the ice-making cylinder 33 to exchange heat with the refrigerant in the evaporator pipe 35, thus forming ice cubes or an ice-water mixture. Subsequently, the drive unit 31 drives the stirring unit 34 to rotate, ensuring sufficient heat exchange between the ice-making slurry and the refrigerant. Simultaneously, the stirring unit 34 delivers the ice cubes or ice-water mixture to the outlet of the ice-making cylinder 33, providing the user with prepared ice cubes or an ice-water mixture to meet their needs.

[0065] It should be noted here that, as Figure 3 As shown, the stirring component 34 includes a blade shaft 341 and stirring blades 342. The stirring blades 342 are fitted onto one end of the blade shaft 341, and the other end of the blade shaft 341 is connected to the shaft 37. By driving the blade shaft 341 and the stirring blades 342 to rotate through the driving component 31, the ingredients in the cold drink can be mixed more evenly, and the cold drink can be conveyed to the outlet of the mixing cylinder 33.

[0066] Among them, Figure 11 As shown, the side wall of the insulation shell 32 has a first mounting hole 321, and the side wall of the material preparation cylinder 33 has a second mounting hole 331. A rotating shaft 37 is rotatably inserted through the first mounting hole 321 and the second mounting hole 331. The output shaft is connected to the stirring member 34 through the rotating shaft 37, so as to connect the stirring member 34 to the driving member 31 located outside the insulation shell 32. In order to prevent the slurry in the material preparation cylinder 33 from leaking from the connection position between the rotating shaft 37 and the material preparation cylinder 33, a sealing device is provided between the rotating shaft 37 and the material preparation cylinder 33.

[0067] Specifically, such as Figure 10 , Figure 12 and Figure 13As shown, a first sealing connection seat 332 is provided between the heat insulation shell 32 and the material preparation cylinder 33. A limiting member 333 is connected to the first sealing connection seat 332. The limiting member 333 is inserted into the second mounting hole 331, and the limiting member 333 is sealed to the second mounting hole 331. The output shaft passes through the limiting member 333, and a first sealing member 334 is provided between the limiting member 333 and the output shaft. The inner ring of the first sealing member 334 is sealed to the output shaft, and the outer ring of the first sealing member 334 is clearance-fitted to the limiting member 333. A second sealing member 335 is provided on the side of the first sealing member 334 facing away from the material preparation cylinder 33, and the inner ring of the second sealing member 335 is sealed to the output shaft.

[0068] It is understandable that by using the first sealing connection seat 332, the limiting member 333, the first sealing member 334 and the second sealing member 335 to assemble between the rotating shaft 37 and the material making cylinder 33, the connection gap between the rotating shaft 37 and the first sealing connection seat 332 and the limiting member 333 can be effectively reduced, and the sealing performance between the rotating shaft 37 and the material making cylinder 33 can be enhanced.

[0069] Since the outer ring of the first seal 334 and the limiting member 333 form a clearance fit, when the rotating shaft 37 rotates, the rotating shaft 37 can form a dynamic sealing connection between the first seal 334, the first sealing connection seat 332, and the limiting member 333. This reduces the wear on the first seal 334 caused by the wear of the rotating shaft 37, extends the service life of the first seal 334, and ensures the sealing performance between the rotating shaft 37 and the first sealing connection seat 332. This effectively reduces the risk of slurry leakage from the material preparation cylinder 33 and ensures the ice-making rate of the beverage machine.

[0070] The first seal 334 and the second seal 335 are preferably made of wear-resistant and corrosion-resistant materials such as PTFE or rubber to ensure that the first seal 334 and the second seal 335 do not wear or corrosion during long-term use.

[0071] Specifically, to ensure a sealing fit between the limiting member 333 and the second mounting hole 331, such as Figures 12 to 14 As shown, the end of the limiting member 333 that is inserted into the second mounting hole 331 has an extended boss 337. The outer ring of the extended boss 337 is sealed and abutted against the inner wall of the material preparation cylinder 33 by a sealing gasket 338. The inner ring of the extended boss 337 is connected to the outer ring of the first sealing member 334 to ensure that the limiting member 333 limits and assembles the first sealing member 334 on the rotating shaft 37. The sealing gasket 338 is used to adapt to the abutment gap between the limiting member 333 and the inner wall of the material preparation cylinder 33, so as to achieve a sealed contact between the limiting member 333 and the inner wall surface of the material preparation cylinder 33, thereby further reducing the risk of slurry leakage from the material preparation cylinder 33.

[0072] It should also be noted that the limiting member 333 has a connecting post, and the connecting post has multiple threaded holes arranged at intervals. The first sealing connecting seat 332 has multiple connecting holes. The first sealing connecting seat 332 is connected to the limiting member 333 by bolts or studs, so as to ensure the ease of assembly between the limiting member 333 and the first sealing connecting seat 332.

[0073] Furthermore, such as Figure 10 , Figure 12 and Figure 13 As shown, a second sealing connector 322 is provided on the outer wall of the heat insulation shell 32. The second sealing connector 322 is detachably connected to the first sealing connector 332 so that the first sealing connector 332 and the second sealing connector 322 form an integral sealing device. The second sealing connector 322 is used to cover the first sealing connector 332 to prevent the first sealing connector 332 from being exposed and affecting the aesthetics of the material preparation system 3.

[0074] The second sealing connector 322 has a sealing boss 323 on the side facing the insulation shell 32, and the first sealing connector 332 has an insertion hole 336. The sealing boss 323 is inserted into the insertion hole 336, and the inner side of the sealing boss 323 abuts against the second sealing member 335. The sealing boss 323 and the second sealing member 335 make a sealing contact, thereby forming a sealing connection at the connection position of the first sealing connector 332 and the second sealing connector 322, and axially limiting the second sealing member 335, further ensuring the sealing performance of the second sealing member 335 on the first sealing connector 332 and the second sealing connector 322.

[0075] It should be noted that in this embodiment, the insertion hole 336 is coaxial with the first mounting hole 321 and the second mounting hole 331, the sealing boss 323 is formed with a hollow hole, and the rotating shaft 37 is rotatably connected to the hollow hole so as to limit and protect the rotating shaft 37 by using the sealing boss 323 of the second sealing connection seat 322, and further ensure the rotational stability of the rotating shaft 37.

[0076] It should also be noted that, in order to facilitate the detachable connection between the first sealing connector 332 and the second sealing connector 322, a connecting boss is formed on the side of the first sealing connector 332 away from the material cylinder 33, and a connecting hole is formed on the second sealing connector 322, so that the first sealing connector 332 and the second sealing connector 322 can be threadedly connected by bolts or studs.

[0077] Furthermore, such as Figure 9 , Figure 10 and Figure 13As shown, the second sealing connection seat 322 is connected to the housing of the driving component 31 via the driving connection seat 311. The driving connection seat 311 contains a transmission assembly, with the output shaft rotatably connected to the active end of the transmission assembly, and the driven end of the transmission assembly rotatably connected to the rotating shaft 37. Thus, the driving component 31 can drive the active end of the transmission assembly to rotate, thereby driving the driven end of the transmission assembly and the rotating shaft 37 to rotate. This allows the rotating shaft 37 to drive the stirring structure inside the material preparation cylinder 33 to rotate, achieving the transfer of ice blocks within the material preparation cylinder 33. Furthermore, the driving connection seat 311 provides dust protection for the transmission assembly and the connection points between the transmission assembly and the driving component 31 and the rotating shaft 37, preventing the driving component 31, the transmission assembly, and the rotating shaft 37 from being directly exposed to the external environment. This ensures effective transmission between the driving component 31, the transmission assembly, and the rotating shaft 37, and guarantees the energy utilization rate of the driving component 31.

[0078] It should be noted that the transmission group preferably uses a gear set to drive the drive component 31 and the rotating shaft 37, in order to reduce the space occupied by the drive connecting seat 311 and improve the space utilization rate of the sealing connection components of the material preparation device. 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.

[0079] It should also be noted that, in order to ensure the connection stability between the second sealing connector 322 and the drive connector 311, a second mounting groove 324 is formed on the side of the second sealing connector 322 away from the thermal insulation shell 32. One side of the drive connector 311 is embedded in the second mounting groove 324 so that the second mounting groove 324 limits and fixes the side of the second sealing connector 322.

[0080] In embodiments of this utility model, such as Figure 15 As shown, the cooling system 2 includes a compressor 21, a throttling device 22, and a condenser 23, all detachably installed inside the casing 1. The compressor 21, condenser 23, and throttling device 22 are sequentially connected via a refrigeration pipeline 24. The outlet of the throttling device 22 is connected to the feed system 3, and the inlet of the compressor 21 is connected to the feed system 3. Furthermore, by sequentially connecting the compressor 21, throttling device 22, condenser 23, and feed system 3 via the refrigeration pipeline 24, the cooling system 2 forms a refrigeration cycle, thereby providing the feed system 3 with condensed refrigerant.

[0081] Specifically, the outlet of compressor 21 is connected to the inlet of the condenser tube of condenser 23, the outlet of the condenser tube of condenser 23 is connected to the inlet of throttling device 22, the outlet of throttling device 22 is connected to the inlet of evaporator pipe 35, and the outlet of evaporator pipe 35 is connected to the inlet of compressor 21. The refrigerant input into compressor 21 is compressed into a high-temperature, high-pressure refrigerant gas by compressor 21, and then input into condenser 23 for condensation to form liquid refrigerant. The liquid refrigerant is input into throttling device 22 for pressure reduction and then input into evaporator pipe 35 so that the low-temperature, low-pressure liquid refrigerant can exchange heat with the slurry in the feed cylinder 33 to realize the ice-making operation of the slurry in feed cylinder 33. After the heat exchange is completed, the liquid refrigerant is converted into a low-temperature, low-pressure gaseous refrigerant and input into compressor 21 for recompression to form the refrigeration cycle of cooling system 2.

[0082] It should be noted that the compressor 21 and the condenser 23 can be installed inside the housing 1 by means of brackets or supports, and the specific connection method is the existing technology; and the installation structure between the condenser tube and the cooling fan in the condenser 23 can also be set by means of brackets, which will not be described in detail here.

[0083] In this embodiment, the cold drink machine is a smoothie maker, an ice cream maker, or a multi-functional smoothie / ice cream maker, and the corresponding functions can be set for the cold drink machine according to actual needs.

[0084] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
