Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically to a double-blade ice smoothie maker. Background Technology

[0002] The smoothie machine is mainly used to make smoothies. The structure of the smoothie machine includes a refrigeration system, a control system and corresponding support structure. The refrigeration system includes a compressor, condenser and evaporator. When making smoothies, only the outside of the evaporator is in contact with the liquid, resulting in low ice-making efficiency. Moreover, the same smoothie machine can only produce smoothies of one particle size at a time. Summary of the Invention

[0003] To overcome the shortcomings of the existing technology, the purpose of this invention is to invent a dual-blade ice-making device that has high ice-making efficiency and can simultaneously produce ice slush of two different particle sizes.

[0004] The present invention adopts the following technical solution:

[0005] A dual-blade slush-making device, comprising,

[0006] The outer casing has a slush cartridge mounting position on its surface.

[0007] A slush tube is installed in the slush tube mounting position. The top of the slush tube has a liquid inlet, the bottom side of the slush tube has a first slush outlet, and the middle side of the slush tube has a second slush outlet.

[0008] The stirring assembly includes a drive unit, a speed adjustment unit, and a stirring blade holder disposed within the housing. The stirring blade holder includes an inner blade holder and an outer blade holder disposed outside the inner blade holder. The top end of the main shaft of the drive unit extends through the housing and is fixedly connected to the outer blade holder. The inner blade holder is sleeved on the outside of the main shaft, and the bottom end of the inner blade holder is placed inside the housing. It is drivenly connected to the main shaft of the drive unit through the speed adjustment unit, which is adapted to adjust the speed of the inner blade holder.

[0009] A refrigeration assembly includes a refrigerant supply unit and an annular evaporator disposed between an inner blade holder and an outer blade holder. The refrigerant supply unit is connected to the annular evaporator via a condensing pipe, and the annular evaporator is wrapped around the outside of the inner blade holder.

[0010] The separating assembly includes a first partition and a second partition. The second partition is installed on the outer side of the top of the annular evaporator. The first partition is sleeved on the outer side of the second partition, and a gap is formed between them. The outer side of the first partition is fixed to the inner wall of the slush cylinder. The lower edge of the second slush outlet is on the same plane as the annular connector, the first partition, and the upper end face of the second partition. The outer blade holder includes a fixed seat fixed to the main shaft, an outer blade body sleeved on the outer side of the annular evaporator, and an annular connector connecting the fixed seat and the outer blade body. The annular connector is slidably installed in the gap.

[0011] Furthermore, the speed adjustment unit includes a first input gear, a second input gear, a first linkage gear, a second linkage gear, a transmission shaft, an output gear, a driven gear, a first switching element, and a drive cylinder. The first input gear and the second input gear are mounted on the outside of the inner tool holder and arranged sequentially from bottom to top along the axial direction of the inner tool holder. One end of the transmission shaft is rotatably connected to the housing, and the other end is rotatably connected to a mounting plate. The outer side of the mounting plate is fixedly connected to the inner wall of the housing. The first linkage gear and the second linkage gear are sleeved on the transmission shaft and arranged sequentially from bottom to top along the axial direction of the transmission shaft. The first linkage gear meshes with the first input gear, and the second input gear meshes with the second linkage gear. The output gear is fixedly connected to the main shaft. The driven gear is fixedly connected to the transmission shaft and meshes with the output gear. The first switching member is disposed between the first linkage gear and the second linkage gear and is slidably connected to the transmission shaft. The first linkage gear and the second linkage gear have protrusions on opposite sides. The first switching member has grooves on both sides that are adapted to the protrusions. The driving cylinder is adapted to drive the first switching member to move toward the first linkage gear or the second linkage gear so that the grooves engage with the protrusions on the first linkage gear or the second linkage gear. The first switching member is adapted to rotate the first linkage gear or the second linkage gear when the grooves engage with the protrusions on the first linkage gear or the second linkage gear.

[0012] Furthermore, the first switching component includes a switching ring sleeved on the transmission shaft and a first connecting rod with one end rotatably connected to the switching ring and the other end connected to the drive cylinder. The groove is formed on both sides of the switching ring, and the switching ring is adapted to move toward the first linkage gear or the second linkage gear under the drive of the drive cylinder.

[0013] Furthermore, the speed adjustment unit also includes a third input gear, a third linkage gear, and a second switching component. The third input gear is mounted on the outside of the inner tool holder and located above the second input gear. The third linkage gear is sleeved on the transmission shaft and located above the second linkage gear. The third linkage gear meshes with the third input gear. The second switching component includes a transmission ring sleeved on the outside of the transmission shaft and a second connecting rod with one end rotatably connected to the transmission ring and the other end connected to the drive cylinder. A sliding rod is provided radially on the side of the third linkage gear facing the second linkage gear. The ends of several sliding rods are slidably connected to the transmission ring. A locking block is provided on the outside of the transmission shaft. A notch adapted to the locking block is opened on the inside of the transmission ring. The transmission ring is adapted to be driven by the drive cylinder to slide along the axial direction of the transmission shaft, so that the locking block is inserted into or passes through the notch. When the locking block is inserted into the notch, the transmission shaft rotates through the locking block and the transmission ring, which in turn rotates the third linkage gear through the sliding rod.

[0014] Furthermore, the inner tool holder includes an inner tool shaft sleeved on the outside of the main shaft and an inner tool body installed on the outside of the inner tool shaft, the inner tool body being arranged in a spiral shape.

[0015] Furthermore, the inner blade body has a plurality of drainage holes evenly distributed on its surface, and the diameter of the drainage holes is 0.5 to 1 mm.

[0016] Furthermore, a first scraper is provided at the bottom end of the outer blade body, and a second scraper is provided at the top end of the outer blade body. The top part of the second scraper is fixedly connected to the annular connector, and the remaining part abuts against the lower end surfaces of the first partition and the second partition, respectively.

[0017] Furthermore, it also includes a liquid inlet pipe. The first partition has an opening near the inner wall of the slush cylinder. One end of the liquid inlet pipe is connected to the opening, and the other end is fitted with a funnel. The funnel is installed at the liquid inlet.

[0018] Furthermore, the annular connector includes a ring body slidably installed in the gap and a plurality of rods evenly arranged on the upper end face of the ring body. A plurality of mounting holes are evenly opened on the ring body. One end of the rod is threaded to the mounting hole, and the other end is fixed to the fixing seat by a bolt. The fixing seat is fixed to the main shaft by a lock nut. A guide plate is provided on the side of the rod.

[0019] Furthermore, the outer side of the slush cartridge mounting position is provided with a slush cartridge mounting groove for cooperating with the outer shell. The bottom of the outer shell is detachably fixed in the slush cartridge mounting groove. The slush cartridge mounting groove includes an annular groove, and the annular groove has a plurality of engagement slots distributed radially. The engagement slot includes a cavity and a limiting top plate located above the cavity.

[0020] The bottom of the slush tube has a slush tube foot, which is adapted to be slidably disposed in the annular groove; the slush tube foot is provided with a plurality of rotating buckles protruding outward, which are adapted to be accommodated in the groove cavity of the screw-on buckle.

[0021] When the rotating buckle is placed in the engaging slot, the top of the rotating buckle is limited by the limiting top plate.

[0022] Beneficial effects:

[0023] This invention improves the efficiency of slush preparation by using an inner and outer blade holder in conjunction with an annular evaporator to simultaneously produce ice from both the inner and outer sides of the evaporator. Furthermore, the inclusion of a first and second partition and a second slush outlet allows the prepared slush to be discharged directly through the second outlet without waiting for all the liquid in the slush cylinder to solidify, enabling rapid discharge from the slush machine. In addition, a speed adjustment unit regulates the rotational speed of the inner and outer blade holders, creating a speed difference that allows for the simultaneous production of slush with two different particle sizes to meet customer taste preferences.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0046] like Figure 1-16 As shown, a dual-blade slush-making device includes,

[0047] The outer casing 10 has a mounting position for the slush tube 20 on its surface;

[0048] A slush tube 20 is installed at the slush tube 20 mounting position. The top of the slush tube 20 has a liquid inlet 201, the bottom side of the slush tube 20 has a first slush outlet 202, and the middle side of the slush tube 20 has a second slush outlet 203.

[0049] The stirring assembly 30 includes a drive unit 301 and a speed adjustment unit 302 disposed within the housing 10, and a stirring blade holder disposed within the smoothie container 20. The stirring blade holder includes an inner blade holder 303 and an outer blade holder 304 disposed outside the inner blade holder 303. The top end of the main shaft of the drive unit 301 extends through the housing 10 and is fixedly connected to the outer blade holder 304. The inner blade holder 303 is sleeved on the outside of the main shaft, and a bearing is provided between the inner blade holder 303 and the main shaft for holding the inner blade holder 303 in place. The inner tool holder 303 is separated from the main spindle to reduce the contact area between the inner tool holder 303 and the main spindle, thus preventing the main spindle from rotating and causing the inner tool holder 303 to rotate. The bottom end of the inner tool holder 303 is placed inside the housing 10 and is connected to the main spindle of the drive unit 301 via the speed adjustment unit 302. The speed adjustment unit 302 is adapted to adjust the speed of the inner tool holder 303. Rotary seals are provided at the connection between the main spindle and the housing 10, as well as at the connection between the inner tool holder 303 and the housing 10, to prevent liquid from seeping in.

[0050] The refrigeration assembly 40 includes a refrigerant supply unit and an annular evaporator 401 disposed between the inner blade holder 303 and the outer blade holder 304. The refrigerant supply unit is connected to the annular evaporator 401 through a condensing pipe. The annular evaporator 401 is wrapped around the outside of the inner blade holder 303. Specifically, the refrigerant supply unit includes a compressor 402, a condenser 403, and an expansion valve, which are the four core components of compression refrigeration. The refrigerant circulates between the compressor 402, the condenser 403, the expansion valve, and the evaporator. The refrigerant inside the evaporator evaporates and absorbs heat, which in turn absorbs heat from the liquid around the evaporator, causing the liquid to cool and gradually transform into a slushy state. This core refrigeration principle is known to those skilled in the art and is not within the scope of the improvement of this invention, so it will not be described in detail here.

[0051] The separating assembly 50 includes a first partition 501 and a second partition 502. The second partition 502 is installed on the outer side of the top of the annular evaporator 401. The first partition 501 is sleeved on the outer side of the second partition 502, forming a gap between them. The outer side of the first partition 501 is fixedly connected to the inner wall of the slush cylinder 20. The lower edge of the second slush outlet 203 is on the same plane as the annular connector 3043, the upper end faces of the first partition 501 and the second partition 502. The outer blade holder 304 includes a fixed base 3041 fixedly connected to the main shaft, an outer blade body 3042 sleeved on the outer side of the annular evaporator 401, and an annular connector 3043 connecting the fixed base 3041 and the outer blade body 3042. The annular connector 3043 is slidably installed on the... Specifically, in this embodiment, the inner side of the first partition 501 and the outer side of the second partition 502 are not in direct contact with the annular connector 3043. There is still a certain gap between the annular connector 3043 and the two partitions to reduce the frictional force on the annular connector 3043 when it rotates. Some of the ice sand can penetrate into the gap and melt under the friction between the annular connector 3043 and the first partition 501 and the second partition 502, forming a water film filling the gap. This water film can lubricate the annular connector 3043, thereby further reducing the frictional force between the annular connector 3043 and the first partition 501 and the second partition 502. At the same time, the water film can prevent the ice sand from continuing to enter the gap, so that the scraped ice sand can move along the second partition 502, the annular connector 3043 and the first partition 501 to the second ice sand outlet 203 for discharge.

[0052] In use, the operator pours liquid into the ice slush cylinder 20 through the liquid inlet 201, immersing both the outer and inner sides of the annular condenser 403 in the liquid. The refrigeration unit 40 then starts working, delivering refrigerant to the annular evaporator 401. The liquid near the outer and inner sides of the annular condenser 403 gradually condenses into ice under the action of the refrigerant in the annular evaporator 401. During rotation, the inner and outer blade holders 304 scrape off the ice adhering to the outer and inner sides of the annular condenser 403. As the ice is scraped off, it is affected by the shearing force of the inner and outer blade holders 304, forming ice slush. The ice slush on the outside of the evaporator is transported to the end of the outer blade holder 304 and then... The ice falls back into the slush cylinder 20. The ice slush inside the evaporator is transported to the top of the annular evaporator 401 by the inner blade holder 303, and then guided to the second ice slush outlet 203. At this time, the operator can open the second ice slush outlet 203 to obtain ice slush. Most of the liquid and the ice slush that is not fully stirred will remain in the lower part of the annular evaporator 401 due to their higher density, which is beneficial to improving the efficiency of ice slush output. Only after all the liquid outside the annular evaporator 401 has solidified into ice slush can the operator open the first ice slush outlet to obtain ice slush. During this process, the outer blade holder 304 will continuously stir the ice-water mixture outside the annular evaporator 401 to prevent the ice slush from solidifying into lumps.

[0053] Furthermore, to meet different taste preferences—for example, some people prefer chewy smoothies (larger particles) while others prefer smoothies with a creamy texture (smaller particles)—we can adjust the rotation speed of the inner blade holder 303 using the speed adjustment unit 302. This allows the inner blade holder 303 and the outer blade holder 304 to rotate at different speeds, enabling the simultaneous production of smoothies with different particle sizes. Specifically, the operator lowers the rotation speed of the inner blade holder 303 using the speed adjustment unit 302 to prolong the time required for condensation on the annular condenser. The contact time between the ice inside the annular condenser 403 and the annular condenser 403 increases the thickness of the ice. The lower the rotation speed of the inner blade holder 303, the longer the contact time between the ice and the annular condenser 403, and the thicker the ice becomes. After being scraped off by the inner blade holder 303, it can form ice crystals with larger particle size. On the other hand, the rotation speed of the outer blade holder 304 is higher than that of the inner blade holder 303. Its scraping speed on the outer side of the annular condenser 403 is faster. The contact time between the ice condensed on the outer side of the annular condenser 403 and the annular condenser 403 is shorter. After being scraped off, it will form ice crystals with smaller particle size.

[0054] This invention, through the coordination of the inner blade holder 303, the outer blade holder 304, and the annular evaporator 401, enables simultaneous ice production on both the inner and outer sides of the evaporator, thereby improving the efficiency of slush preparation. Simultaneously, the inclusion of a first partition 501, a second partition 502, and a second slush outlet 203 allows the prepared slush to be directly discharged through the second slush outlet 203 without waiting for all the liquid in the slush cylinder 20 to solidify, achieving rapid discharge from the slush machine. Furthermore, the included speed adjustment unit 302 can adjust the speed of the inner blade holder 303, creating a speed difference between the inner blade holder 303 and the outer blade holder 304, enabling the simultaneous production of slush with two different particle sizes to meet customer taste preferences.

[0055] Specifically, in this embodiment, the speed adjustment unit 302 includes a first input gear 3021, a second input gear 3022, a first linkage gear 3024, a second linkage gear 3025, a transmission shaft 3027, an output gear 3028, a driven gear 3029, a first switching element 3030, and a drive cylinder 3031. The first input gear 3021 and the second input gear 3022 are mounted on the outside of the inner tool holder 303 and can rotate together with the inner tool holder 303. The first input gear 3021 and the second input gear 3022 are arranged sequentially from bottom to top along the axial direction of the inner tool holder 303. One end of the transmission shaft 3027 is rotatably connected to the outer casing 10, and the other end is rotatably connected to a mounting plate 3032. The outer side of the mounting plate 3032 is fixedly connected to the inner wall of the outer casing 10. The first linkage gear 3024 and the second linkage gear 3025 are sleeved on the transmission shaft 3027 and can rotate relative to the transmission shaft 3027. The first linkage gear 3024 and the second linkage gear 3025 are arranged sequentially from bottom to top along the axial direction of the transmission shaft 3027. The first linkage gear 3024 meshes with the first input gear 3021, and the second input gear 3022 meshes with the second linkage gear 3025. The output gear 3028 is fixedly connected to the main shaft, and the driven gear 3029 is fixedly connected to the transmission shaft 3027. The driven gear 3029 meshes with the output gear 3028. This arrangement... This configuration allows the drive unit 301 to rotate the transmission shaft 3027 via the driven gear 3029 when it is working. However, since the first linkage gear 3024 and the second linkage gear 3025 are rotatably mounted on the transmission shaft 3027, the rotation of the transmission shaft 3027 will not drive the first linkage gear 3024 and the second linkage gear 3025 to rotate, and therefore will not drive the inner tool holder 303 to rotate. Therefore, the first switching member 3030 needs to be used to connect the first linkage gear 3024 or the second linkage gear 3025 to the transmission shaft 3027, so that the transmission shaft 3027 can drive the first linkage gear 3024 or the second linkage gear 3025 to rotate, and thus drive the inner tool holder 303 to rotate. The first input gear 3021 or the second input gear 3022, which meshes with the first input gear 3025, drives the inner tool holder 303 to rotate. In this embodiment, the transmission ratio between the first linkage gear 3024 and the first input gear 3021 is different from the transmission ratio between the second linkage gear 3025 and the second input gear 3022, thereby adjusting the different rotational speeds of the inner tool holder 303. The first switching member 3030 is disposed between the first linkage gear 3024 and the second linkage gear 3025 and is slidably connected to the transmission shaft 3027. The first linkage gear 3024 and the second linkage gear 3025 have protrusions 3033 on opposite sides, and the first switching member 3030 has grooves 30303 on both sides that are adapted to the protrusions 3033.The drive cylinder 3031 is adapted to drive the first switching member 3030 to move toward the first linkage gear 3024 or the second linkage gear 3025, so that the groove 30303 engages with the protrusion 3033 on the first linkage gear 3024 or the second linkage gear 3025. When the groove 30303 engages with the protrusion 3033 on the first linkage gear 3024 or the second linkage gear 3025, the first switching member 3030 is adapted to rotate the first linkage gear 3024 or the second linkage gear 3025. During switching, the drive cylinder 3031 drives the first switching member 3030 toward the first linkage gear. The first switching member 3030 moves in the direction of the first switching member 3024 or the second linkage gear 3025, causing the first switching member 3030 to press against the first linkage gear 3024 or the second linkage gear 3025. The protrusion 3033 will contact the surface of the first switching member 3030 and drive the first linkage gear 3024 or the second linkage gear 3025 to rotate under the action of friction, thereby driving the inner tool holder 303 to rotate. During this process, the first linkage gear 3024 or the second linkage gear 3025 that is in contact with the first switching member 3030 will be affected by the reaction force given by the inner tool holder 303, so that the rotational speed of the first linkage gear 3024 or the second linkage gear 3025 is lower than that of the first switching member 3024 or the second linkage gear 3025. At a rotational speed of 30, the first linkage gear 3024 or the second linkage gear 3025 rotates relative to the first switching member 3030 until it rotates to the position where the groove 30303 corresponds to the protrusion 3033. At this point, the protrusion 3033 embeds into the groove 30303, completing the transmission connection between the first switching member 3030 and the first linkage gear 3024 or the second linkage gear 3025. At this time, the drive unit 301 can fully transmit power to the first linkage gear 3024 or the second linkage gear 3025. However, if switching is performed during use, the drive unit 301 must be turned off first, and the drive cylinder 3031 drives the first switching member 3030 to engage with the first linkage gear 3024 or the second linkage gear 3025. The moving gear 3024 or the second linkage gear 3025 separates and moves towards another linkage gear, referred to here as linkage gear A, causing the protrusion 3033 to engage with the surface of linkage gear A. During this process, linkage gear A will rotate under the drive of the input gear within it, while the first switching member 3030 will continue to rotate due to inertia. At this time, there is a speed difference between linkage gear A and the first switching member 3030. After the first switching member 3030 engages with linkage gear A, relative rotation will occur, allowing the protrusion 3033 to rotate to the engagement position of the groove 30303 and embed itself therein, completing the transmission connection between the first switching member 3030 and linkage gear A.

[0056] Specifically, in this embodiment, the first switching member 3030 includes a switching ring 30301 sleeved on the transmission shaft 3027 and a first connecting rod 30302 with one end rotatably connected to the switching ring 30301 and the other end connected to the drive cylinder 3031. The groove 30303 is formed on both sides of the switching ring 30301. The switching ring 30301 is adapted to move toward the first linkage gear 3024 or the second linkage gear 3025 under the drive of the drive cylinder 3031.

[0057] During operation, the drive cylinder 3031 drives the switching ring 30301 to move toward the first linkage gear 3024 or the second linkage gear 3025 via the first connecting rod 30302 until the switching ring 30301 is in contact with the protrusion 3033 on the first linkage gear 3024 or the second linkage gear 3025.

[0058] Furthermore, to avoid excessive pressure on the surface of the first linkage gear 3024 or the second linkage gear 3025 when the drive cylinder 3031 drives the switching ring 30301 to contact the first linkage gear 3024 or the second linkage gear 3025, in this embodiment, the first connecting member can be slidably connected to the drive cylinder 3031, that is, the first connecting member can slide along the axial direction of the drive cylinder 3031. Then, two springs 30344 are respectively set on both sides of the first connecting member, and the two springs 30344 are... A limiting plate 30445 is provided at the end away from the first connecting member. Both limiting plates 30445 are fixedly connected to the side of the drive cylinder 3031. Two springs 30344 are sleeved on the drive cylinder 3031. At this time, the first connecting member will be relatively fixed to the drive cylinder 3031 under the combined action of the two springs 30344. With this setting, when switching, if the drive cylinder 3031 drives the switching ring 30301 toward the first linkage gear 3024 through the first connecting rod 30302, The drive cylinder 3031 drives the two limiting plates 30445 downward, causing the first connecting rod 30302, which is held by the two springs 30344, to move downward until the switching ring 30301 contacts the first linkage gear 3024. The drive cylinder 3031 continues to move downward, and the spring 30344 above the first connecting rod 30302 will deform due to the resistance of the first connecting rod 30302. At this time, the switching ring 30301 acts on the first linkage gear 3024. The pressure is equal to the elastic force generated when the spring 30344 deforms. It is much smaller than the pressure of the switching ring 30301 pressing against the first linkage gear 3024 when the drive cylinder 3031 is fixed to the first connecting rod 30302. This can prevent the switching ring 30301 from applying too much pressure to the first linkage gear 3024, which could lead to damage to the first linkage gear 3024, the switching ring 30301, or the first connecting rod 30302. It can also provide sufficient pressure for the groove 30303 and the protrusion 3033 to fit together.

[0059] Furthermore, in this embodiment, the speed adjustment unit 302 further includes a third input gear 3023, a third linkage gear 3026, and a second switching member 3034. The third input gear 3023 is mounted on the outside of the inner tool holder 303 and located above the second input gear 3022. The third linkage gear 3026 is sleeved on the transmission shaft 3027 and located above the second linkage gear 3025. The third linkage gear 3026 can rotate relative to the transmission shaft 3027 and meshes with the third input gear 3023. The second switching member 3034 includes a transmission ring 303 sleeved on the outside of the transmission shaft 3027. 41 and a second connecting rod 30343, one end of which is rotatably connected to the transmission ring 30341 and the other end of which is connected to the drive cylinder 3031. The transmission ring 30341 is disposed between the third linkage gear 3026 and the second linkage gear 3025. The third linkage gear 3026 has a sliding rod 30261 arranged radially on the side facing the second linkage gear 3025. The ends of several sliding rods 30261 are slidably connected to the transmission ring 30341. This arrangement allows the transmission ring 30341 to slide axially along the transmission shaft 3027 and also drive the third linkage gear 3026 to move together. The several sliding rods 30261 can distribute the load. The driving force transmitted from the transmission ring 30341 to the third linkage gear 3026 is prevented from breaking. To facilitate the transmission of power from the transmission shaft 3027 to the third linkage gear 3026 via the transmission ring 30341, a locking block 30271 is provided on the outer edge of the transmission shaft 3027. A notch 30342 adapted to the locking block 30271 is provided on the inner side of the transmission ring 30341. Multiple locking blocks 30271 and notches 30342 can be provided, depending on the actual situation. This arrangement ensures that when the locking block 30271 is inserted into the notch 30342, the transmission shaft 3027 is connected to the transmission gear 3026 via the locking block 30271. The ring 30341 rotates, which in turn drives the third linkage gear 3026 to rotate via the slide rod 30261. When it is necessary to switch the second linkage gear 3025, the drive cylinder 3031 drives the switching ring 30301 to move upward via the first connecting rod 30302. The second connecting rod 30343 will drive the transmission ring 30341 to move upward until the switching ring 30301 abuts against the second linkage gear 3025. At this time, the locking block 30271 located on the outside of the transmission shaft 3027 will pass through the notch 30342, thereby preventing the locking block 30271 and the notch 30342 from maintaining a transmission connection when the switching ring 30301 is engaged with the second linkage gear 3025.

[0060] Specifically, when it is necessary to connect the third linkage gear 3026 to the drive shaft 3027, the drive unit 301 must first be shut down. The drive cylinder 3031 drives the drive ring 30341 to move up or down via the second connecting rod 30343. If the drive shaft 3027 was originally connected to the first linkage gear 3024, the drive cylinder 3031 drives the drive ring 30341 to move up. If the drive shaft 3027 was originally connected to the second linkage gear 3025, the drive cylinder 3031 drives the drive ring 30341 to move up. 41. Move downwards until the transmission ring 30341 contacts the locking block 30271. At this point, both the transmission shaft 3027 and the transmission ring 30341 continue to rotate due to inertia. However, due to the different transmission ratios of the third linkage gear 3026 and the third input gear 3023, there is a speed difference between the transmission shaft 3027 and the transmission ring 30341. This causes the transmission ring 30341 to rotate relative to the locking block 30271 after contact. When the rotational speed decreases to a certain level, the locking block 30271 can align with and embed itself into the notch 30342, thereby completing the transmission connection between the drive shaft 3027 and the third linkage gear 3026. Furthermore, to prevent excessive output force from causing the drive ring 30341 or locking block 30271 to break when the drive cylinder 3031 drives the drive ring 30341 to abut against the locking block 30271, in this embodiment, the second connecting rod 30343 can also be slidably connected to the drive cylinder 3031, and the second connecting rod 30343... Two springs 30344 are provided at both ends of the connection with the drive cylinder 3031. A fixing seat 3041 is provided at the end of the two springs 30344. The two springs 30344 clamp the second connecting plate. During switching, the elastic force generated by the springs 30344 presses the transmission ring 30341 onto the locking block 30271. The force is much less than the pressure exerted on the locking block 30271 when the second connecting rod 30343 is fixed to the drive cylinder 3031, thus effectively preventing damage to the locking block 30271 or the transmission components during switching.

[0061] Furthermore, to facilitate the scraping of ice shavings by the inner blade holder 303 and their transport to the top of the annular evaporator, the inner blade holder 303 in this embodiment includes an inner blade shaft 3031 sleeved on the outside of the main shaft and an inner blade body 3032 installed on the outside of the inner blade shaft 3031. The inner blade body 3032 is spirally arranged, and the spiral inner blade body 3032 can simultaneously transport the ice shavings upward while scraping them. In order to avoid leaving too much liquid in the ice shavings transported by the inner blade body 3032, multiple drainage holes are evenly opened on the surface of the inner blade body 3032 to drain the liquid remaining in the ice shavings. The diameter of the drainage holes is 0.5 to 1 mm, which can prevent too much ice shavings from being discharged from the drainage holes when draining liquid.

[0062] Furthermore, since the ice scraped off by the outer blade 3042 is transported upwards, and the outer blade 3042 is located below the first partition 501 and the second partition 502, some of the ice will contact and remain on the lower surfaces of the first partition 501 and the second partition 502 during the upward transport of the ice. This ice will then be continuously compressed and form ice blocks, affecting the rotation of the annular connector 3043. To avoid this problem, a second scraper 3045 is provided at the top of the outer blade 3042. The top part of the second scraper 3045 is connected to... The annular connector 3043 is fixedly connected, and the remaining parts abut against the lower end surfaces of the first partition 501 and the second partition 502 respectively. This arrangement can scrape away the ice sand remaining on the lower end surfaces of the first partition 501 and the second partition 502, preventing it from accumulating over a long period of time and forming ice blocks that hinder the rotation of the annular connector. It can also guide the ice sand transmitted to the top of the outer blade 3042 to the outside of the outer blade 3042, so as to cooperate with the first scraper 3044 provided at the bottom of the outer blade 3042, allowing the ice sand to move to the first ice sand outlet 202 and be discharged.

[0063] Furthermore, for ease of disassembly and installation, in this embodiment, the annular connector 3043 includes a ring 30431 slidably installed within the gap and several rods 30432 evenly arranged on the upper surface of the ring 30431. The ring 30431 has several evenly spaced mounting holes. One end of each rod 30432 is threaded into one of the mounting holes, and the other end is bolted to the fixing seat 3041. The fixing seat 3041 is fixed to the main shaft via a locking nut. During disassembly, the locking nut is separated from the main shaft, and then the bolt is separated from the fixing seat 3041, allowing the fixing seat 3041 to be removed. Then, the rods 30432 can be rotated. 32. Remove the rod 30432. At this time, the operator can remove the slush cylinder 20 from the outer shell 10 to clean the outer blade holder 304 and the inner blade holder 303. In order to facilitate the movement of the slush conveyed by the inner blade holder 303 to the annular evaporator 401 to the second slush outlet 203, a guide plate 30433 is provided on the side of the rod 30432 in this embodiment. The guide plate 30433 can rotate together with the annular body 30431, thereby discharging the slush conveyed to the top of the annular evaporator 401 outward, so that the slush can move outward along the upper surface of the second partition 502, the annular body 30431 and the first partition 501 to the second slush outlet 203.

[0064] Specifically, the outer side of the slush tube 20 mounting position is provided with a slush tube 20 mounting groove for cooperating with the outer shell 10. The bottom of the outer shell 10 is detachably fixed in the slush tube 20 mounting groove. The slush tube 20 mounting groove includes an annular groove 101. The annular groove 101 has a plurality of screw-fit grooves 102 distributed radially. The screw-fit groove 102 includes a cavity 1021 and a limiting top plate 1022 located above the cavity 1021.

[0065] The bottom of the slush tube 20 has a slush tube foot 204, which is adapted to be slidably disposed in the annular groove 101; the slush tube foot 204 is provided with a plurality of rotating buckles 205 protruding in the outer direction, which are adapted to be accommodated in the groove 1021 of the screw-fit groove 102.

[0066] When the rotating buckle 205 is placed in the engagement slot 102, the top of the rotating buckle 205 is limited by the limiting top plate 1022.

[0067] The connection between the smoothie bucket and the 20-position smoothie tube is as follows:

[0068] The outer side of the slush tube 20 mounting position is provided with a slush tube 20 mounting groove for cooperating with the outer shell 10. The bottom of the outer shell 10 is detachably fixed in the slush tube 20 mounting groove. The slush tube 20 mounting groove includes a ring groove 101. The ring groove 101 has a plurality of screw-fit grooves 102 distributed radially. The screw-fit groove 102 includes a hollow cavity 1021 and a limiting top plate 1022 located above the cavity 1021. Correspondingly, the bottom of the smoothie bucket has a ring of smoothie bucket feet 204, which are adapted to slide within the annular groove 101. Simultaneously, several rotating latches 205 protrude along the outer direction of the smoothie bucket feet 204. When the operator places the smoothie bucket feet 204 into the annular groove 101 and rotates them, the rotating latches 205 can enter the engagement slot 102. At this time, because the rotating latches 205 are restricted by the upper limiting plate 1022, the smoothie bucket cannot be directly separated from the smoothie bucket 20 mounting position, thus establishing a connection between the smoothie bucket and the smoothie bucket at the smoothie bucket 20 mounting position. To disassemble the smoothie bucket, rotate it in the opposite direction to disengage the rotating latches 205 from the engagement slot 102, at which point the smoothie bucket can be lifted upwards to separate it from the smoothie bucket 20 mounting position.

[0069] In addition, to facilitate the operator to inject liquid into the outside of the annular evaporator 401, this embodiment also includes a liquid inlet pipe. The first partition 501 has an opening 503 near the inner wall of the ice slush cylinder 20. One end of the liquid inlet pipe is connected to the opening 503, and the other end is equipped with a funnel. The funnel is installed at the liquid inlet 201.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted herein.
