[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a sealing connection component for a material preparation device and a cold drink machine. Background Technology
[0002] As a highly efficient, convenient, and multifunctional beverage making device, cold drink machines are widely used in various catering establishments and home kitchens. Existing cold drink machines mainly consist of a refrigeration system and a stirring system. When the machine is operating, the refrigeration system delivers cooled refrigerant to the evaporator in the mixing cylinder of the stirring system. The refrigerant exchanges heat with the liquid water inside the mixing cylinder, turning the liquid water into ice cubes or iced beverages. The stirring system then transports the ice cubes outside the mixing cylinder for the user to enjoy.
[0003] To prevent liquid water leakage, a sealing device is required between the stirring system's shaft and the mixing cylinder. However, during actual operation of the beverage cooler, the sealing device gradually wears down due to the continuous rotation and friction of the shaft, leading to a decrease in sealing performance. This results in a risk of liquid water leakage from the mixing cylinder, affecting the ice-making rate of the beverage cooler.

[0005] To address the shortcomings of existing technologies, this invention provides a sealing connection component for a material preparation device and a beverage cooler, which can improve the service life of the sealing device, effectively reduce the risk of liquid water leakage from the material preparation cylinder, and ensure the ice-making rate of liquid water in the beverage cooler.
[0006] To solve the above-mentioned technical problems, this utility model provides a sealing connection component for a material preparation device, comprising:
[0007] The thermal insulation outer shell has a first mounting hole formed on its side wall;
[0008] A material preparation cylinder is installed inside the heat insulation shell. The material preparation cylinder has a second mounting hole, and a rotating shaft is rotatably inserted through the second mounting hole and the first mounting hole.
[0009] A first sealing connection seat is connected between the heat insulation shell and the material preparation cylinder. The first sealing connection seat is connected to a limiting member, which is inserted into the second mounting hole and is sealed to the second mounting hole.

The inner ring of the first sealing member is sealed to the rotating shaft, and the outer ring of the first sealing member forms a clearance fit with the limiting member.
[0011] As an improvement to the above solution, one end of the limiting member inserted into the second mounting hole is formed with an extended boss. The outer ring of the extended boss is sealed and abutted against the inner wall of the material cylinder by a sealing gasket. The inner ring of the extended boss is connected to the outer ring of the first sealing member.
[0012] As an improvement to the above solution, a second sealing element is provided on the side of the first sealing element away from the material preparation cylinder, and the inner ring of the second sealing element is sealed to the rotating shaft.
[0013] As an improvement to the above solution, the first sealing connection seat is formed at a preset height, and the distance between the inner side of the heat insulation shell and the outer side of the material preparation cylinder is equal to the preset height.
[0014] As an improvement to the above solution, it also includes:
[0015] The second sealing connector is disposed on the outer side wall of the insulation shell. The second sealing connector is detachably connected to the first sealing connector, and the size of the second sealing connector is larger than the size of the first mounting hole.
[0016] As an improvement to the above solution, a sealing boss is formed on the side of the second sealing connector facing the first sealing connector, and the first sealing connector is formed with a insertion hole.

[0022] Implementing this utility model has the following beneficial effects:
[0023] According to this embodiment, the sealing connection component of the material preparation device includes a first sealing connection seat, a limiting member, and a first sealing element. The sealing device is assembled between the rotating shaft and the material preparation cylinder, effectively ensuring the assembly stability of the sealing device. Because the outer ring of the first sealing element and the limiting member form a clearance fit, when the rotating shaft rotates, the rotating shaft can form a dynamic sealing connection between the first sealing element, the first sealing connection seat, and the limiting member. This reduces the wear on the first sealing element caused by shaft wear, extends the service life of the first sealing element, and ensures the sealing performance between the rotating shaft and the first sealing connection seat.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0031] The sealing connection component of the material preparation device of this utility model can improve the service life of the sealing device, effectively reduce the risk of liquid water leakage from the material preparation cylinder 2, and ensure the ice-making rate of liquid water in the cold drink machine.
[0032] In a specific embodiment of this utility model, as shown in Figures 1 to 6, the sealing connection component of the material preparation device includes an insulating shell 1, a material preparation cylinder 2, and a first sealing connection seat 3. A first mounting hole 11 is formed on the side wall of the insulating shell 1. The material preparation cylinder 2 is installed inside the insulating shell 1, and a second mounting hole 21 is formed in the material preparation cylinder 2. A rotating shaft 7 rotatably passes through the second mounting hole 21 and the first mounting hole 11. The first sealing connection seat 3 connects the insulating shell 1 and the material preparation cylinder 2. A limiting member 31 is connected to the first sealing connection seat 3. The limiting member 31 is inserted into the second mounting hole 21, and the limiting member 31 is sealed to the second mounting hole 21. The rotating shaft 7 passes through the limiting member 31. A first sealing member 32 is provided between the rotating shaft 7 and the limiting member 31. The inner ring of the first sealing member 32 is sealed to the rotating shaft 7, and the outer ring of the first sealing member 32 forms a clearance fit with the limiting member 31.
[0033] According to this embodiment, the sealing connection component of the material preparation device includes a sealing device consisting of a first sealing connection seat 3, a limiting member 31, and a first sealing member 32, which is assembled between the rotating shaft 7 and the material preparation cylinder 2, effectively ensuring the assembly stability of the sealing device. Since the outer ring of the first sealing member 32 forms a clearance fit with the limiting member 31, when the rotating shaft 7 rotates, the rotating shaft 7 can form a dynamic sealing connection with the first sealing member 32, the first sealing connection seat 3, and the limiting member 31. This reduces the wear on the first sealing member 32 caused by the wear of the rotating shaft 7, extends the service life of the first sealing member 32, and ensures the sealing performance between the rotating shaft 7 and the first sealing connection seat 3, thereby effectively reducing the risk of liquid water leakage from the material preparation cylinder 2 and ensuring the liquid water ice-making rate of the beverage machine.
[0034] It should be noted that the first seal 32 is preferably made of wear-resistant and corrosion-resistant materials such as PTFE or rubber to ensure that the first seal 32 will not wear or corrode during long-term use.
[0035] In this embodiment, the first sealing connection seat 3 can be limited and assembled in the second mounting hole 21 of the material preparation cylinder 2 by the limiting member 31, and the sealing performance between the first sealing connection seat 3 and the material preparation cylinder 2 is guaranteed by the sealing connection between the limiting member 31 and the side wall of the second mounting hole 21.
[0036] Specifically, to ensure a sealed fit between the limiting member 31 and the second mounting hole 21, as shown in Figures 3 to 5, an extended boss 311 is formed at one end of the limiting member 31 that is inserted into the second mounting hole 21. The outer ring of the extended boss 311 is sealed against the inner wall of the material preparation cylinder 2 by a sealing gasket 312. The inner ring of the extended boss 311 is connected to the outer ring of the first sealing member 32 to ensure that the limiting member 31 limits and assembles the first sealing member 32 onto the rotating shaft 7. The sealing gasket 312 can deform under pressure to adaptively fill the gap between the connecting surfaces. Thus, the sealing gasket 312 adapts to the abutment gap between the extended boss 311 of the limiting member 31 and the inner wall of the material preparation cylinder 2, achieving a sealed contact between the limiting member 31 and the inner wall of the material preparation cylinder 2. This prevents liquid in the material preparation cylinder 2 from leaking from the abutment position between the limiting member 31 and the inner wall of the material preparation cylinder 2, further reducing the risk of liquid water leakage from the material preparation cylinder 2.
[0037] Optionally, the limiting member 31 is made of elastic material such as rubber. When the limiting member 31 is inserted into the second mounting hole 21, the side wall of the limiting member 31 rebounds and tightly abuts against the side wall surface of the second mounting hole 21 to further enhance the sealing performance between the limiting member 31 and the material cylinder 2.
[0038] Of course, the limiting member 31 is not limited to elastic materials such as rubber, and can also be made of rigid materials. When the limiting member 31 is made of rigid materials, the limiting member 31 and the first sealing connection seat 3 can be detachably connected to ensure the ease of assembly between the limiting member 31 and the first sealing connection seat 3.
[0039] Specifically, as shown in Figures 3 and 5, the limiting member 31 has a connecting post 313, and the connecting post 313 has multiple threaded holes arranged at intervals. The first sealing connecting seat 3 has multiple connecting holes. When the first sealing connecting seat 3 and the limiting member 31 are assembled into the material cylinder 2, the connecting post 313 of the limiting member 31 can be passed through the second mounting hole 21, and the first sealing connecting seat 3 and the limiting member 31 can be connected by bolts or studs, thereby ensuring the ease of assembly between the limiting member 31 and the first sealing connecting seat 3.
[0040] Furthermore, a second seal 33 is provided on the side of the first seal 32 away from the material cylinder 2. The inner ring of the second seal 33 is sealed to the rotating shaft 7, and the outer ring of the second seal 33 abuts against the limiting member 31. The second seal 33 is used to further reduce the connection gap between the limiting member 31 and the rotating shaft 7, thereby further enhancing the sealing performance between the rotating shaft 7 and the limiting member 31.
[0041] Specifically, the inner ring of the second seal 33 is formed with a sealing lip, and the cross section of the sealing lip is a bevel, so that an oil seal is formed between the rotating shaft 7, the limiting member 31, and the first sealing connection seat 3 through the second seal 33, thereby using the second seal 33 in conjunction with the first seal 32 to provide stable and reliable sealing performance for the rotating shaft 7, the limiting member 31, and the first sealing connection seat 3.
[0042] In this embodiment, to ensure the installation stability of the first sealing connector 3, the first sealing connector 3 is formed at a preset height, and the distance between the inner side of the insulation shell 1 and the outer side of the material preparation cylinder 2 is equal to the preset height. Therefore, when the first sealing connector 3 is assembled between the insulation shell 1 and the material preparation cylinder 2, the inner side of the insulation shell 1 and the outer wall of the material preparation cylinder 2 can be used to clamp and fix the first sealing connector 3, and the limiting member 31 passing through the second mounting hole 21 can be used to connect the first sealing connector 3, ensuring the assembly stability of the first sealing connector 3 between the insulation shell 1 and the material preparation cylinder 2, and preventing the first sealing connector 3 from shaking and affecting the sealing performance of the first sealing element 32.
[0043] In this embodiment, as shown in Figures 2 to 5, the sealing connection component of the material preparation device further includes a second sealing connection seat 4. The second sealing connection seat 4 is disposed on the outer side wall of the insulation shell 1. The second sealing connection seat 4 is detachably connected to the first sealing connection seat 3, and the size of the second sealing connection seat 4 is larger than the size of the first mounting hole 11. Therefore, when the second sealing connection seat 4 is connected to the outer side wall of the insulation shell 1, the second sealing connection seat 4 can block the first mounting hole 11, preventing the internal components of the insulation shell 1 from being exposed, thus achieving dust protection for the insulation shell 1.
[0044] It should be noted that, in order to detachably connect the first sealing connector 3 and the second sealing connector 4, the first sealing connector 3 and the second sealing connector 4 are connected to form an integral sealing device. The first sealing connector 3 has a connecting boss 35 on the side away from the material cylinder 2, and the second sealing connector 4 has a connecting hole. When assembling the first sealing connector 3 and the second sealing connector 4, the connecting boss 35 of the first sealing connector 3 passes through the mounting hole on the side wall of the insulation shell 1, and the first sealing connector 3 and the second sealing connector 4 are threaded together using bolts or studs.
[0045] Furthermore, as shown in Figures 3 to 5, a sealing boss 41 is formed on the side of the second sealing connector 4 facing the first sealing connector 3, and an insertion hole 34 is formed on the first sealing connector 3. The sealing boss 41 is inserted into the insertion hole 34, and the inner side of the sealing boss 41 abuts against the second sealing member 33. The sealing boss 41 and the second sealing member 33 are in sealing contact, thereby forming a sealing connection at the connection position of the first sealing connector 3 and the second sealing connector 4, and axially limiting the second sealing member 33, further ensuring the sealing performance of the second sealing member 33 on the first sealing connector 3 and the second sealing connector 4.
[0046] It should be noted that in this embodiment, the insertion hole 34 is coaxial with the first mounting hole 11 and the second mounting hole 21, the sealing boss 41 is formed with a hollow hole, and the rotating shaft 7 is rotatably connected to the hollow hole so as to limit and protect the rotating shaft 7 by using the sealing boss 41 of the second sealing connection seat 4, and further ensure the rotational stability of the rotating shaft 7.
[0047] As shown in Figure 6, the outer wall of the thermal insulation shell 1 has a first mounting groove 12, and the second sealing connector 4 is embedded in the first mounting groove 12. The first mounting groove 12 limits and fixes the outer wall of the second sealing connector 4, thereby further ensuring the stability of the second sealing connector 4 in the thermal insulation shell 1.
[0048] In embodiments of this utility model, as shown in Figures 1 and 2, the sealing connection component of the material preparation device further includes a drive connection seat 5. One side of the drive connection seat 5 is connected to the second sealing connection seat 4, and the other side of the drive connection seat 5 is connected to a drive member 6. A transmission assembly (not shown in the figures) is provided inside the drive connection seat 5. The output shaft of the drive member 6 is rotatably connected to the active end of the transmission assembly, and the driven end of the transmission assembly is rotatably connected to the rotating shaft 7. Thus, the drive member 6 can drive the active end of the transmission assembly to rotate, thereby driving the driven end of the transmission assembly and the rotating shaft 7 to rotate. This allows the rotating shaft 7 to drive the stirring structure inside the material preparation cylinder 2 to rotate, realizing the transfer of ice blocks within the material preparation cylinder 2.
[0049] By using the drive connector 5 to provide dust protection for the transmission assembly and the connection between the transmission assembly and the drive component 6 and the rotating shaft 7, the drive component 6, the transmission assembly and the rotating shaft 7 can be prevented from being directly exposed to the external environment, ensuring effective transmission between the drive component 6, the transmission assembly and the rotating shaft 7, and ensuring the energy utilization rate of the drive component 6.
[0050] It should be noted that the drive connector 5 may include a detachably connected first connector and a second connector to facilitate maintenance and repair of the transmission assembly inside the drive connector 5. The first connector is connected to the housing of the drive motor, and the second connector is connected to the second sealed connector 4. The front end of the rotating shaft 7 is rotatably connected to the second connector via a bearing to further ensure the rotational stability of the rotating shaft 7.
[0051] It should also be noted that the transmission group preferably uses a gear set to drive the drive component 6 and the rotating shaft 7, in order to reduce the space occupied by the drive connecting seat 5 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.
[0052] As shown in Figure 2, the second sealing connector 4 has a second mounting groove 42 formed on the side opposite to the heat insulation shell 1. One side of the drive connector 5 is embedded in the second mounting groove 42 to limit and fix the side of the second sealing connector 4, thereby ensuring the connection stability between the second sealing connector 4 and the drive connector 5.
[0053] It should be noted that, in order to further ensure the connection stability between the drive connecting seat 5 and the second sealing connecting seat 4, multiple threaded countersunk holes are formed in the second mounting groove 42, and multiple threaded holes are formed in the drive connecting seat 5. When one side of the drive connecting seat 5 is fitted into the second mounting groove 42, 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 connecting seat 5 and the second sealing connecting seat 4.
[0054] Accordingly, this utility model also provides a cold drink machine, which includes the sealing connection component of the mixing device described in any of the above embodiments, wherein the cold drink machine is a smoothie machine, an ice cream machine, or a multi-functional machine for making smoothies and ice cream. Using the cold drink machine of this embodiment can improve the service life of the sealing device, effectively reduce the risk of liquid water leakage from the mixing cylinder 2, and ensure the ice-making rate of liquid water in the cold drink machine. At the same time, the cold drink machine possesses all the beneficial effects of the aforementioned sealing connection component of the mixing device, which will not be elaborated further here.
[0055] It should be noted that a support plate is formed inside the cold drink machine, and the heat preservation shell 1 and the drive component 6 are assembled in the support plate to realize the installation and fixation of the sealing connection component of the material preparation device in the cold drink machine.
[0056] 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.
