Abstract
Description
Technical Field
[0001] This utility model relates to a smoothie machine, and more particularly to a snowflake smoothie machine. Background Technology
[0002] A smoothie maker is a device used to make smoothies. It works by having an evaporator come into contact with liquids such as fruit juice, absorbing heat from the liquid and causing it to freeze quickly to form a smoothie. Currently, the evaporator in existing smoothie makers is located inside the device. Disassembly requires removing most of the casing and parts that obstruct the evaporator's removal, making disassembly and assembly cumbersome and inconvenient for maintenance.
[0003] Furthermore, existing smoothie machines use a liquid immersion evaporator to cool the liquid as a whole. However, the evaporator needs to cool the entire liquid, resulting in low smoothie production efficiency and making it difficult for users to visually monitor the smoothie production progress. If continuous smoothie production were achieved by controlling the liquid flow through the evaporator, only a liquid pump or similar equipment would be needed for metered liquid delivery. This method is complex, difficult to control, and has high manufacturing costs. Utility Model Content

[0026] Implementing the embodiments of this utility model has the following beneficial effects:
[0027] The solution describes a water passage chamber with an overflow outlet at its bottom and an opening at its top that is a predetermined distance above the lowest point of the evaporator. A water storage tank is also provided within the evaporator housing. The water passage chamber is located below the evaporator housing, and an outlet is located at the bottom of the water storage tank, lower than the overflow outlet. During normal operation, the water storage tank discharges water into the water passage chamber through the outlet. As the water level at the bottom of the water passage chamber rises, the water storage tank stops discharging water when it overflows the outlet, thus maintaining a stable water level within the water passage chamber. If the water level in the water passage chamber is too high, excess water can flow out through the overflow outlet, further ensuring a safe water level in the passage chamber and maintaining the water level in contact with the evaporator. This ensures continuous and stable ice production by the evaporator, resulting in low component cost and reliable operation.
[0028] This solution introduces refrigerant into the evaporator through a first refrigerant pipe. The refrigerant evaporates and absorbs heat inside the evaporator, generating a low temperature that causes the liquid to condense on the evaporator surface. Finally, the liquid separates from the evaporator under the action of a scraper and falls into a container below the scraper, continuously generating snowflake-like ice slush. It has high ice-making efficiency and the ice-making process is quite visually appealing, making it suitable for commercial and household promotion.
[0029] The evaporator housing cavity has an installation port on one side, with an installation plate provided therein, allowing the evaporator to be easily installed and removed. The end face of the evaporator has an external sealing structure to seal the end face of the evaporator to the evaporator housing cavity. The rotating shaft on one side has a first refrigerant pipe and a second refrigerant pipe extending into the evaporator, as well as an internal sealing structure to seal the second refrigerant pipe to the evaporator. This ensures continuous cooling of the evaporator and guarantees the sealing of the evaporator housing cavity and the pipes leading into the evaporator, resulting in stable and reliable operation and a long service life.

[0038] 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.
[0039] like Figures 1-5As shown in the figure, a specific embodiment of this utility model provides a snowflake smoothie machine, including a housing 1 and an evaporator 2. The housing 1 is provided with an evaporator receiving cavity 11 and a water passage cavity 12. The evaporator receiving cavity 11 is provided with an installation port 13 on one side, and the installation port 13 is provided with an installation plate 14. The evaporator 2 includes a cylinder 21 and a rotating shaft 22 provided on both sides of the cylinder 21. The installation plate 14 is provided with a bearing hole 23 for connecting the rotating shaft 22. The bearing hole 23 is provided with a bearing 24 for mounting the rotating shaft 22. The evaporator 2 is disposed within the evaporator housing cavity 11, and a scraper 3 is provided on one side of the evaporator 2; an external sealing structure 4 is provided on the end face of the evaporator 2, which is used to seal the end face of the evaporator 2 with the evaporator housing cavity 11; a first refrigerant pipe 5 and a second refrigerant pipe 6 extending into the interior of the evaporator 2 are provided on one side of the rotating shaft portion 22, and an internal sealing structure 8 is provided to seal the second refrigerant pipe 6 with the evaporator 2; the evaporator 2 can be driven by the rotating drive mechanism 7 to rotate relative to the housing 1, the first refrigerant pipe 5 and the second refrigerant pipe 6.
[0040] In this design, refrigerant is introduced into the evaporator 2 through the first refrigerant pipe 5. The refrigerant evaporates and absorbs heat within the evaporator, causing the evaporator 2 to reach a low temperature. This causes the liquid to condense on the surface of the evaporator 2, and finally, under the action of the scraper 3, it separates from the evaporator 2 and falls into a container below the scraper 3. This process continuously generates snowflake-like ice slush, resulting in high ice-making efficiency and a visually appealing process, making it suitable for commercial and residential applications. The evaporator cavity 11 has an installation port 13 on one side, with an installation plate 14 attached to it. The evaporator 2 can be easily installed and removed through the installation port 13. The evaporator 2 has an external sealing structure 4 on its end face, which is used to seal the end face of the evaporator 2 with the evaporator housing cavity 11. The rotating shaft 22 on one side has a first refrigerant pipe 5 and a second refrigerant pipe 6 extending into the evaporator 2, as well as an internal sealing structure 8 for sealing the second refrigerant pipe 6 with the evaporator 2. This ensures continuous cooling of the evaporator 2 and ensures that the rotating evaporator 2 can seal the evaporator housing cavity 11 and the pipes entering the evaporator 2. The operation is stable and reliable, and the service life is long.
[0041] To improve the ease of installation and removal of the mounting plate 14 and to ensure that the evaporator 2 can be installed into the evaporator receiving cavity 11 through the mounting port 13, the mounting port 13 is provided with a limiting screw hole 131 on its edge, and the mounting plate 14 is fixed to the surface of the mounting port 13 through the limiting screw hole 131; the outline of the mounting port 13 is larger than the cross-sectional outline of the evaporator 2.
[0042] Combination Figure 6As shown, in order to enhance the seal between the end face of the evaporator 2 and the evaporator housing cavity 11, this embodiment uses a dedicated external sealing structure 4. The external sealing structure 4 includes an external sealing element 41 and a limiting ring 42 that protrudes axially from the end face of the evaporator 2. The external sealing element 41 includes a first sealing part 411 located outside the limiting ring 42, a sealing clearance part 412 located between the limiting ring 42 and the corresponding rotating shaft part 22, a second sealing part 413 that abuts against the inner wall of the evaporator housing cavity 11, and a third sealing part 414 that abuts against the rotating shaft part 22.
[0043] Preferably, the limiting ring 42 has a limiting skirt 421 extending radially outward, and the first sealing part 411 has an outer sealing positioning part 415 embedded between the limiting skirt 421 and the end face of the evaporator 2, and a sealing protrusion 416 provided on the opposite side of the outer sealing positioning part 415, the sealing protrusion 416 abutting against the inner wall of the evaporator receiving cavity 11.
[0044] The evaporator housing 11 is directly provided with a bearing hole 23 and / or is provided with the bearing hole 23 through the mounting plate 14. A clearance space 416 is provided between the limiting ring 42 and the rotating shaft 22, and the sealing clearance part 412 is provided in the clearance space. The second sealing part 413 extends from the front of the sealing clearance part 412 and abuts against the inner wall of the bearing hole 23. A sealing groove 221 is provided on the surface of the rotating shaft 22, and the third sealing part 414 is embedded in the sealing groove 221.
[0045] With the aforementioned external sealing structure 4, the first sealing part 411 can be fixed on the limiting skirt 421, ensuring that the first sealing part 411 can seal the inner wall of the evaporator receiving cavity 11 using the sealing flange 416. The clearance space and the sealing clearance part 412 form an air chamber between the sealing flange 416 and the second sealing part 413, improving the sealing performance of the moving parts through graded sealing. The rotating shaft part 22 has a sealing groove 221 on its surface, and the third sealing part 414 is embedded in the sealing groove 221, which can fix the external sealing structure 4 as a whole on the evaporator 2, ensuring its sealing reliability when rotating with the evaporator 2.
[0046] In some specific embodiments, the rotating shaft portion 22 on one side is provided with a hollow cavity 222, through which the first refrigerant pipe 5 and the second refrigerant pipe 6 extend into the interior of the evaporator 2; the hollow cavity 222 and the first refrigerant pipe 5, and the hollow cavity 222 and the second refrigerant pipe 6 are both provided with the inner sealing structure 8. The inner sealing structure 8 includes a first sealing ring 81 and a first Glyd ring 82, which are arranged sequentially from the direction away from the interior of the evaporator 2. The first sealing ring 81 serves as the first layer of seal, and the first Glyd ring 82 is composed of a rubber O-ring 821 and a polytetrafluoroethylene (PTFE) ring 822. When the rubber O-ring is compressed, it will compress the PTFE ring, maintaining a stable seal of the rotating part for a long time.
[0047] Preferably, a second Glyd ring 83 is also provided on the outer side of the first Glyd ring 82. The use of two sets of Glyd rings improves sealing reliability and extends the service life of the evaporator 2.
[0048] Combination Figure 7 As shown, in one embodiment, the inner end face of the evaporator 2 is provided with an oil return guide groove 9, and the side wall where the second refrigerant pipe 6 extends into the interior of the evaporator 2 is provided with an oil return hole 61, and the oil return guide groove 9 and the oil return hole 61 are correspondingly arranged.
[0049] The oil return guide groove 9 includes an oil return guide section 91 radially arranged along the inner wall of the end face of the evaporator 2 and a gripping section 92 located at the junction of the end face and the front face of the evaporator 2. The end of the oil return guide section 91 is directly opposite the oil return hole 61. When the evaporator 2 rotates, the sleeve oil return guide groove 9 rotates accordingly, guiding the cooling oil in the evaporator 2 through the gripping section 92 to the oil return guide section 91, and finally into the oil return hole 61. The gripping section 92 has a guide arc surface.
[0050] To facilitate the disassembly and assembly of the evaporator 2 and improve the ease of equipment maintenance, a limiting groove 62 is provided on the outer side of the second refrigerant pipe 6. The housing 1 is provided with a retaining plate 63 for fixing the second refrigerant pipe 6. The retaining plate 63 has a bayonet 631, which extends into the limiting groove 62 to fix the second refrigerant pipe 6. When it is necessary to disassemble the evaporator 2, the screws fixing the retaining plate 63 can be loosened, and then the retaining plate 63 can be removed from the limiting groove 62.
[0051] The rotary drive mechanism 7 includes a motor 71, a reduction mechanism 72, a first pulley, a second pulley 74, and a transmission belt 73. The motor 71 is connected to the reduction mechanism 72. The reduction mechanism 72 is provided with the first pulley. The rotating shaft 22 is provided with the second pulley 74. The transmission belt 73 connects the first pulley and the second pulley 74.
[0052] In other embodiments, the drive belt 73 and pulley can be replaced by a gear drive mechanism, a chain drive mechanism, or a worm gear mechanism. Furthermore, the power source for the rotary drive mechanism 7 can be replaced by a hydraulic drive mechanism or a pneumatic drive mechanism.
[0053] Combination Figure 8 As shown, the casing 1 also houses a compressor 10 and a condenser 101. The first refrigerant pipe 5, evaporator 2, second refrigerant pipe 6, compressor 10, and condenser 101 are connected in sequence. The first refrigerant pipe 5 connects the condenser 101 and the evaporator 2. Refrigerant flowing from the condenser 101 enters the evaporator 2 through the first refrigerant pipe 5. The second refrigerant pipe 6 connects the evaporator 2 and the compressor 10. In the evaporator 2, some refrigerant evaporates and absorbs heat. The gaseous refrigerant and the remaining liquid refrigerant are sent to the compressor 10 through the second refrigerant pipe 6. After being pressurized by the compressor 10, they are sent to the condenser 101 for the next heat transfer. The bottom of the water passage 12 is provided with an overflow port 121, and the top of the overflow port 121 has an rim 122 that is a predetermined distance above the lowest point of the evaporator 2. The evaporator housing cavity 11 is also provided with a water storage tank 15. The water passage cavity 12 is provided below the evaporator housing cavity 11. The bottom of the water storage tank 15 is provided with a water outlet 151, which is lower than the overflow outlet 121.
[0054] It should be noted that during normal operation, the water storage tank 15 discharges water into the water passage chamber 12 through the outlet 151. As the water level at the bottom of the water passage chamber 12 rises, the water storage tank 15 stops discharging water when the water overflows the outlet 151, thus maintaining the water level in the water passage chamber 12. When the water level in the water passage chamber 12 is too high, excess water can flow out from the overflow outlet 121, further ensuring the water level in the water passage chamber 12 and maintaining the water level in contact with the evaporator 2, thereby ensuring that the evaporator 2 can continuously and stably produce ice.
[0055] 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 utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
