Description

Technical Field

[0001] This utility model relates to the technical field of refrigeration equipment, and in particular to a slush-making device for a slush machine. Background Technology

[0002] A slush machine, also known as a slush maker, is a cold beverage appliance that freezes liquid sugary drinks such as cola, wine, coffee, soda water, juice, chocolate, and milk into a refreshing, melted beverage. The refrigeration components of a slush machine include a compressor, condenser, and evaporator. The compressor and condenser are standard parts and only need to be matched according to the required cooling efficiency. The direct factor affecting the cooling effect is the design of the evaporator, which determines the heat exchange area and the amount of cold air conduction loss, thus directly affecting the overall cooling efficiency of the refrigeration system. Currently, both commercial and household slush machines immerse the evaporator in the beverage solution, exchanging heat between the evaporator's outer wall and the beverage solution inside the tank. However, the drawbacks of this cooling method are obvious, as follows:

[0003] Traditional evaporators have a small heat exchange area, resulting in low refrigeration efficiency: Traditional evaporators rely on the cylindrical outer wall for unilateral refrigeration and heat exchange, which limits the contact conduction area between the outer wall of the evaporator and the beverage solution. The small refrigeration and heat exchange area directly limits the refrigeration efficiency of the refrigeration components.

[0004] Traditional evaporators suffer from significant heat transfer losses: the refrigerant enters the copper tube windings through the inlet pipe, undergoing a heat exchange process where it changes from a liquid to a gaseous state, causing the copper tube windings to release heat. The copper tube windings then transfer the heat to the stainless steel tube wall of the evaporator, and finally, the stainless steel tube wall transfers the heat to the beverage solution. Therefore, the heat transfer from refrigerant evaporation to the beverage solution involves two different media. The more media layers there are, the greater the heat loss. Furthermore, only a portion of the copper tubes are in contact with the stainless steel tube wall. In addition, the copper tube windings and the stainless steel tube wall of the evaporator cannot fit perfectly together, resulting in a small contact area that greatly reduces the heat transfer effect. Less than 30% of the actual heat transfer reaches the beverage solution.

[0005] Traditional slush machines work by completely immersing the evaporator in the beverage solution. In addition, the cylindrical evaporator cools only one side, resulting in wasted cold energy in the middle of the evaporator. Furthermore, the excessive number of cold energy transfer medium layers and the small contact area lead to significant cold energy loss. Therefore, traditional slush machines often take 45 minutes or even more than an hour to make 2 liters of slushies. This technology, which has been used for more than ten years, is both time-consuming and energy-intensive, and cannot meet the needs of various sudden, impromptu cold drinks.

[0006] To address the inefficiency of traditional evaporators, this invention proposes a dual-cylinder coaxial refrigeration and dual-spiral synchronous propulsion ice-making device. By expanding the heat exchange area, optimizing the cold energy conduction path and ice-sand delivery efficiency, the ice-sand production speed and energy efficiency ratio are significantly improved. Utility Model Content

[0007] In order to solve the above-mentioned problems in the prior art, the present invention provides a slush-making device for a slush machine.

[0008] The above-mentioned problems of the present invention are solved by the following technical solutions:

[0009] An ice-making device for a slush machine, used to be inserted into the beverage container of the slush machine for ice making, comprising,

[0010] An evaporator installed inside a beverage container includes an inner cylinder and an outer cylinder arranged coaxially. The outer cylinder is spaced outside the inner cylinder so that the interlayer between the inner and outer cylinders forms an annular condensation chamber, which simultaneously cools both the inner and outer cylinders.

[0011] It also includes,

[0012] An outer screw frame is provided outside the outer cylinder, and the outer screw frame forms a first ice outlet channel on the outer wall of the outer cylinder for pushing ice sand on the outer wall of the outer cylinder.

[0013] An inner screw is located inside the inner cylinder, and a second ice outlet channel is formed on the inner screw for propelling the ice sand in the inner cylinder;

[0014] The inner screw and the outer screw are driven to the same power component to form synchronous motion.

[0015] By adopting the above technical solutions, the inner wall of the inner cylinder and the outer wall of the outer cylinder are cooled simultaneously, expanding the heat exchange area and improving the cooling efficiency. Furthermore, the use of a double spiral synchronous propulsion enhances the fineness of the shaved ice, better meeting consumers' quality demands for "smooth and creamy shaved ice" and improving ice dispensing efficiency, perfectly adapting to the demand for instant cold drinks.

[0016] A further provision of the above technical solution is that the inner screw includes a drive shaft and inner spiral blades formed on the outer circumferential surface of the drive shaft, and the inner spiral blades are continuously arranged to form a continuous spiral second ice outlet channel.

[0017] A further provision of the above technical solution is that the outer screw frame includes a transmission sleeve, a rotating frame integrally formed with the transmission sleeve, and an outer helical blade formed on the rotating frame;

[0018] The transmission sleeve and the drive shaft are connected in a limiting connection and are connected to the output shaft of the power assembly so that the inner cylinder and the outer cylinder rotate synchronously.

[0019] A further configuration of the above technical solution is as follows: the output end of the first ice outlet channel is formed with an ice receiving area, and the ice slush output from the first ice outlet channel and the second ice outlet channel enter the ice receiving area together, and after being guided by the ice receiving area, it is output to the outlet of the beverage container.

[0020] A further configuration of the above technical solution is that the output end of the second ice outlet channel and the input end of the ice receiving area are infinitely close to being in the same axial position.

[0021] By adopting the above technical solution, when the output end of the second ice outlet channel pushes out ice sand, the ice sand falls and directly enters the ice receiving area, where it is completely received.

[0022] A further provision of the above technical solution is that the ice-receiving area is a guide blade formed spirally on the outer screw frame, and the surface of the guide blade forms a guide surface.

[0023] A further provision of the above technical solution is that the guide vane is formed at the tail of the outer helical blade; the output end of the guide vane is configured as a radially extending surface.

[0024] By adopting the above technical solution and setting a vertical outlet surface, the smoothie is output with a vertical downward speed, which can directly connect with the outlet, thus preventing the smoothie from falling into other parts of the beverage container and reducing the smoothie output rate.

[0025] A further provision of the above technical solution is that the tail end of the inner helical blade is formed with a radial output cross-section, and the starting end of the guide blade is formed with an input cross-section that is infinitely close to the output cross-section and is in the same vertical plane.

[0026] By adopting the above technical solution, the ice shavings output from the second ice outlet channel, after reaching the end of the inner spiral blade, can fall vertically downward along the output scissor due to the setting of the output scissor, and continue to enter the guide surface vertically downward along the output scissor of the guide blade in the ice receiving area.

[0027] A further provision of the above technical solution is that: a partition is provided circumferentially in the condensing chamber, the partition axially separating the condensing chamber into an input chamber and at least one sub-chamber, and the partition has a notch connecting two adjacent chambers.

[0028] A further provision of the above technical solution is that when there are two or more partitions, the gaps on adjacent partitions are staggered.

[0029] By adopting the above technical solution, the gaps on the partition are staggered, so that the cold medium needs to go through two turns during the movement, forming an S-shaped movement path, which further increases the movement path of the cold medium. The purpose is to avoid the cold medium being directly transported from one gap to the next during the movement, which would shorten the transport path and prevent it from playing a role in rapid cooling.

[0030] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0031] 1. This utility model adopts double-wall synchronous cooling of the inner cylinder inner wall and the outer cylinder outer wall to expand the heat exchange area. At the same time, it adopts a double-spiral synchronous propulsion and precise connection design of the ice receiving area to improve the fineness of the shaved ice, which better meets consumers' quality demand for "fine shaved ice" and improves the ice dispensing efficiency, perfectly adapting to the demand for instant cold drinks.

[0032] 2. With the "partitioned staggered + S-shaped refrigerant path" design in the condensing chamber, the refrigerant can fully absorb the cooling capacity. Furthermore, the special refrigerant inlet and outlet structure ensures the continuity of the refrigerant during the input and output process. This ensures that the movement of the refrigerant within the refrigeration chamber is also continuous. The refrigerant circulates directly in the condensing chamber between the two cylinders, and the cooling capacity is directly transferred to the beverage solution through the inner and outer cylinder walls. This ensures the stability and uniformity of the cooling effect, eliminates the intermediate loss layer, greatly improves the utilization rate of cooling capacity, and significantly reduces operating costs.

[0033] 3. When the refrigerant is introduced into the refrigeration chamber through the refrigerant inlet, the rapid input speed and the vaporization of the refrigerant upon entering the refrigeration chamber due to temperature changes, which generates a small amount of gas, result in a jet-like input pattern at the refrigerant inlet. This leads to unstable refrigerant input. In this embodiment, a stop member is provided in the jet direction to receive most of the jetted refrigerant, ensuring a stable and continuous input.

[0054] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0055] like Figure 1-11As shown in the figure, this embodiment provides a slush-making device for a slush machine.

[0056] A slush machine's slush-making device includes,

[0057] An evaporator is installed inside a beverage container 700. The evaporator includes an inner cylinder 200 and an outer cylinder 100 arranged coaxially. A closed condensing chamber a is formed between the inner cylinder 200 and the outer cylinder 100 for the circulation of the refrigerant medium only. The condensing chamber a cools both the inner cylinder 200 and the outer cylinder 100 simultaneously.

[0058] It also includes,

[0059] An inner screw 500 is provided inside the inner cylinder 200, and a second ice outlet channel 501 is formed on the inner screw 500 for propelling the ice sand in the inner cylinder 200;

[0060] An outer screw frame 600 is provided outside the outer cylinder 100, and the outer screw frame 600 forms a first ice outlet channel 601 on the outer wall of the outer cylinder 100 for pushing ice sand on the outer wall of the outer cylinder 100.

[0061] The inner screw 500 and the outer screw frame 600 are driven to the same power component to form synchronous motion;

[0062] The output end of the first ice outlet channel 601 is formed with an ice receiving area. The ice slush output from the first ice outlet channel 601 and the second ice outlet channel 501 enters the ice receiving area together, and is then guided by the ice receiving area and output to the discharge port 701 of the beverage container 700.

[0063] The above is the basic scheme of this embodiment.

[0064] Specific reference Figure 1 and Figure 2 As shown, the slush-making device of this embodiment is used to make ice inside the beverage cylinder 700 of a snow melting machine. It includes an inner cylinder 200 and an outer cylinder 100 arranged coaxially. The outer cylinder 100 is spaced outside the inner cylinder 200 so that the inner cylinder 200 and the outer cylinder 100 are in a concentric circle shape. The interlayer between the inner cylinder 200 and the outer cylinder 100 forms an annular and uniform condensing chamber a. A cold medium is introduced into the condensing chamber a to absorb heat and cool the two side walls of the condensing chamber a, so that the walls of the inner cylinder 200 and the outer cylinder 100 are both at low temperatures. The liquid raw materials that come into contact with the inner cylinder 200 and the outer cylinder 100 are rapidly cooled and solidified on the surface. The slush on the outer cylinder 100 is solidified on the outer wall of the outer cylinder 100, and the slush in the inner cylinder 200 is solidified on the inner wall of the inner cylinder 200.

[0065] The inner screw 500 is located inside the inner cylinder 200 and is very close to the inner wall of the inner cylinder 200. When the inner screw 500 rotates relative to the inner cylinder 200, it scrapes off the ice that has condensed on the inner wall of the inner cylinder 200 and drops it into the inner cavity of the inner cylinder 200. Due to the second ice outlet channel 501 on the inner screw 500, the scraped ice is received. During the rotation of the inner screw 500, the ice is pushed forward along the second ice outlet channel 501 and pushed from the tail of the second ice outlet channel 501 to the output end (front end).

[0066] Meanwhile, the outer screw frame 600 is fitted onto the outer wall of the outer cylinder 100 and is very close to the outer wall of the outer cylinder 100. When the outer screw frame 600 rotates relative to the outer cylinder 100, it scrapes off the ice that has condensed on the outer wall of the outer cylinder 100 and drops it into the first ice outlet channel 601 formed between the outer screw frame 600 and the outer cylinder 100. The ice then moves forward along the first ice outlet channel 601 and from the tail of the first ice outlet channel 601 to the output end (front end).

[0067] Regarding the connection method between the inner screw 500 and the outer screw frame 600, the specific configuration in this embodiment is as follows: a drive shaft 510 is axially arranged on the inner screw 500, and the front end of the drive shaft 510 is connected to the output shaft 4 of the power component; while a transmission sleeve 610 is provided on the outer screw frame 600 near the output end, and the transmission sleeve 610 is limitedly connected to the output end of the drive shaft 510, that is, the end opposite to the output shaft 4; when the output shaft 4 of the power component rotates, it drives the drive shaft 510 (inner screw 500), which in turn drives the transmission sleeve 610 (outer screw frame 600), thereby causing the inner screw 500 and the outer screw frame 600 to rotate synchronously at the same time.

[0068] To ensure that the ice slush output from the first ice outlet channel 601 and the second ice outlet channel 501 has the same speed, in this embodiment, the inner screw 500 and the outer screw frame 600 are driven to the same power component to form synchronous motion, thereby ensuring that the output ice slush has consistency.

[0069] In this embodiment, the inner screw 500 includes a drive shaft 510 and an inner spiral blade 520 formed on the outer peripheral surface of the drive shaft 510. The inner spiral blade 520 is continuously arranged to form a continuous spiral second ice outlet channel 501.

[0070] Specific reference Figure 5As shown, the drive shaft 510 is located at the center of the entire device. The inner spiral blade 520 is formed on the outer periphery of the drive shaft 510 and is set in a spiral shape. The outer end of the inner spiral blade 520 is infinitely close to the inner wall of the inner cylinder 200. Thus, the inner spiral blade 520 cleverly divides the inner cavity of the inner cylinder 200 into a spiral closed channel. The scraped ice can only enter the second ice outlet channel 501 and smoothly advance along the ice outlet channel.

[0071] In this embodiment, the specific implementation of the outer screw frame 600 is as follows: the outer screw frame 600 includes a transmission sleeve 610, a rotating frame 640 integrally formed with the transmission sleeve 610, and an outer helical blade 650 formed on the rotating frame 640, wherein the guide blade 620 is formed at the tail of the outer helical blade 650.

[0072] The transmission sleeve 610 and the drive shaft 510 are connected in a limiting manner and are connected to the output shaft 4 of the power assembly so that the inner cylinder 200 and the outer cylinder 100 rotate synchronously.

[0073] In this embodiment, the limiting method between the transmission sleeve 610 and the drive rod is set as follows: the output end of the drive shaft 510 is set as a limiting head 611, that is, a non-circular output head, and the transmission sleeve 610 is provided with a limiting hole that cooperates with the limiting head 611, so as to make a limiting connection with the limiting head 611.

[0074] A typical slush machine only has one outlet 701. Therefore, the output ends of the first ice outlet channel 601 and the second ice outlet channel 501 need to be located at the same output position, and the slush output from the first ice outlet channel 601 and the second ice outlet channel 501 should have the same output direction. At the same time, to avoid mutual obstruction, the slush output from the first ice outlet channel 601 and the second ice outlet channel 501 should not interfere with or block each other. Therefore, in this embodiment, an ice-receiving area is formed at the output end of the first ice outlet channel 601. The output ends of the first ice outlet channel 601 and the second ice outlet channel 501 are both connected to the ice outlet area, so that the slush pushed out by the two ice outlet channels can enter the ice outlet area. Under the action of gravity, the slush falls along a preset path and directly enters the specially designed ice-receiving area, where it is fully received and output along the ice outlet area to the outlet 701, ensuring that the slush does not scatter to other parts.

[0075] The outer helical blade 650 is a strip structure arranged in a helical shape. In this embodiment, two outer helical blades 650 are arranged in a centrally symmetrical manner.

[0076] To ensure that the ice slush output from the second ice outlet channel 501 and the ice slush output from the first ice outlet channel 601 can enter the ice receiving area together, the output end of the second ice outlet channel 501 and the input end of the ice receiving area are infinitely close to being in the same axial position.

[0077] Specific reference Figure 2 and Figure 3 As shown, the output end of the second ice outlet channel 501 is located inside the ice receiving area. That is, when the device is in a lying position, the ice receiving area will rotate to below the output end of the second ice outlet channel 501 as the outer screw frame 600 rotates. At this time, when ice sand falls from the output end of the second ice outlet channel 501, it falls directly into the ice receiving area. In order to avoid ice sand falling into the gap between the second ice outlet channel 501 and the ice receiving area, in this embodiment, the output end of the second ice outlet channel 501 and the ice receiving area are almost seamlessly connected. That is, in the axial direction, the output end of the second ice outlet channel 501 and the input end of the ice receiving area are located on the same vertical line or close to the same vertical line. In this way, when the output end of the second ice outlet channel 501 pushes out ice sand, the ice sand falls and directly enters the ice receiving area, where it is completely received.

[0078] In other embodiments, the output end of the second ice outlet channel 501 can also be flexibly positioned directly above the ice receiving area so that the ice sand can enter the ice receiving area more smoothly.

[0079] Specifically, the ice-receiving area is a guide vane 620 formed spirally on the outer screw frame 600, and the surface of the guide vane 620 forms a guide surface.

[0080] Furthermore, the output end of the guide vane 620 is provided with a radial outgoing surface 621 to optimize the flow direction of the slush.

[0081] In other words, refer to the specific Figure 4 As shown, the guide surface 621 is a vertical plane and is located above the discharge port 701. When the ice slush is smoothly pushed along the guide surface to the position of the guide surface 621, it will fall vertically along the guide surface 621 and fall into the discharge port 701.

[0082] Compared to other types of guide vanes 620, this embodiment cleverly sets a vertical outlet surface 621 so that the slush has a vertical downward speed when it is output, and can directly connect with the discharge port 701, avoiding the slush from falling into other positions inside the beverage container 700, thereby significantly improving the slush output rate.

[0083] Due to the unique design of the spiral shape, the end face of the inner spiral blade 520 is designed as an inclined surface. In order to ensure the perfect connection between the second ice outlet channel 501 and the ice receiving area, in this embodiment, the tail of the inner spiral blade 520 is specially formed with a radial output cut surface 521, and the starting end of the guide blade 620 is also correspondingly formed with an input cut surface 622 that is infinitely close to the output cut surface 521 and is in the same vertical plane.

[0084] Based on the above ingenious design, the ice slush output from the second ice outlet channel 501, after reaching the end of the inner spiral blade 520, can fall vertically downward along the output cut surface 521 due to the clever design of the output cut surface 521, and continue to smoothly enter the guide surface in a vertically downward direction along the output cut surface 521 of the guide blade 620 in the ice receiving area.

[0085] Preferably, to avoid unnecessary shaking of the guide vane 620 during rotation, in this embodiment, a connecting plate 630 is specially provided at the center of the outer screw frame 600. The connecting plate 630 and the inner end of the guide vane 620 are integrally formed, and two guide vanes 620 are symmetrically connected at the center. At the same time, the transmission sleeve 610 is also formed at the center of the connecting plate 630. In this way, the stability of the guide vane 620 is achieved. When the drive shaft 510 drives the transmission sleeve 610, the guide vane 620 is smoothly driven through the connecting plate 630.

[0086] The guide vane 620 is formed at the tail of the outer helical blade 650, and the blade width is greater than that of the outer helical blade 650, so that it can carry more slush.

[0087] In addition, in this embodiment, a partition 300 is provided circumferentially inside the condensing chamber a. The partition 300 isolates the condensing chamber a into an input chamber a' and at least one sub-chamber a'' along the axial direction, and the partition 300 is provided with a notch 301 to connect two adjacent chambers.

[0088] The cold medium is introduced into the condensing chamber a and transported from the first end to the second end along the axial direction of the condensing chamber a; after the cold medium is introduced into the first end of the condensing chamber a, it fills the interlayer space at the first end along the annular structure, and is transported towards the second end, thereby filling the entire annular condensing chamber a.

[0089] Specific reference Figure 6 and Figure 7 As shown, the inner cylinder 200 has two axially oriented ends with connecting bent flanges 210. After the flanges 210 are bent toward the outer cylinder 100, they are fixed to the inner wall of the outer cylinder 100, so that the condensation chamber a forms a sealed structure.

[0090] The refrigerant is introduced from the first end of the condensing chamber a to cool the condensing chamber a. Due to the blocking effect of the partition 300, the refrigerant diffuses radially and circumferentially and is initially located within the input chamber a'. When the input chamber a' is filled, due to the continuous introduction of refrigerant from the first end, the refrigerant in the input chamber a' overflows from the opening 301 of the partition 300 and enters the sub-chamber a'', continuing to fill the sub-chamber a'' until the entire condensing chamber a is filled, thereby cooling the inner and outer walls of the condensing chamber a.

[0091] Based on the above settings, in this embodiment, due to the setting of the partition 300, the movement path of the cold medium in the condensing chamber a has at least one bend, thereby extending the movement path of the cold medium and enabling the cold medium to fully vaporize during its movement in the condensing chamber a, so that it is completely in a gaseous state when it moves to the second end.

[0092] The vaporization process of the cold medium in the condensing chamber a is an endothermic process. Due to the long path, the cold medium is fully vaporized during the movement. In other words, when the cold medium is transported from the first end to the second end, it can absorb a large amount of heat, thereby rapidly cooling the cooling surface and greatly improving the cooling efficiency.

[0093] Preferably, in this embodiment, the partition 300 is configured as an annular structure with a notch, which holds the inner cylinder 200 circumferentially.

[0094] Specific reference Figure 8 As shown, in this embodiment, the inner and outer rings of the partition 300 abut against the outer wall of the inner cylinder 200 and the inner wall of the outer cylinder 100, respectively, so that each separated chamber is sealed except for the notch 301, which allows communication. In other words, the cold medium can only be transported from the notch 301, ensuring the transport path of the cold medium.

[0095] Preferably, in this embodiment, the partition 300 is an annular ring or annular piece with a notch.

[0096] Preferably, in this embodiment, when the number of partitions 300 is set to two or more, the gaps 301 between two adjacent partitions 300 are staggered.

[0097] Specific reference Figure 9As shown, in this embodiment, two partitions 300 are arranged axially in the condensing chamber a, dividing the condensing chamber a into an input chamber a' and two sub-chambers a''. When the cold medium passes through the input chamber a' and the two sub-chambers a'' in sequence, it needs to go through two turns, forming an S-shaped movement path, which further increases the movement path of the cold medium. The notches 301 on the two adjacent partitions 300 are staggered to avoid the cold medium being directly transported from one notch 301 to the next notch 301 during the movement, thereby eliminating the looping path of the intermediate sub-chambers a'', shortening the transport path, and failing to achieve the effect of rapid cooling.

[0098] In this embodiment, the inner cylinder 200 is provided with a refrigerant inlet 201 and a return gas inlet for the refrigerant to enter and exit, and the refrigerant inlet 201 and the return gas inlet are respectively connected to the first end and the second end of the condensing chamber a.

[0099] The condensing chamber a is divided into multiple chambers. The input chamber a' is located at the first end, and the last sub-chamber a'' is the second end. The refrigerant inlet 201 is located in the input chamber a', and the return gas outlet is located in the last sub-chamber a''. The refrigerant is input from the refrigerant inlet 201 into the input chamber a', and moves sequentially along the input chamber a' and multiple sub-chambers a'' to the return gas outlet, forming a gas output.

[0100] Specific reference Figure 8 As shown, in this embodiment, the refrigerant inlet 201 is provided with a capillary tube 1 for inputting the refrigerant, and the return gas inlet is provided with an outlet pipe 2 for outputting the vaporized gas.

[0101] Preferably, the inner diameter of the capillary tube 1 is smaller than the inner diameter of the outlet tube 2. The purpose of this is to reduce the unit input amount of the refrigerant so that the refrigerant can fully absorb heat and vaporize in the refrigeration chamber, thereby increasing the output amount of gas, accelerating the movement speed of the refrigerant in the refrigeration chamber, and improving the refrigeration efficiency.

[0102] In this embodiment, to ensure the continuity of refrigerant input and output, both the refrigerant inlet 201 and the return gas inlet are provided with arc-shaped grooves 220 protruding toward the center of the inner cylinder 200.

[0103] Specific reference Figure 10 As shown, the refrigerant inlet 201 and the return gas inlet are both small holes set on the inner cylinder 200, and the cylinder wall near the small hole is set as an arc-shaped groove with the protruding direction facing the center of the inner cylinder 200.

[0104] Based on the above configuration, when refrigerant is input, it accumulates in the groove before being input through refrigerant inlet 201. Because the inner diameter of refrigerant inlet 201 is small, the externally input refrigerant completely fills the arc-shaped groove 220 before entering refrigerant inlet 201, ensuring a continuous flow of refrigerant input without any discontinuity. Similarly, refrigerant gas input from the return gas port first accumulates in the arc-shaped groove 220 before being output from the return gas port, thus ensuring the continuity of the output gas as well.

[0105] The special refrigerant inlet 201 and return port structure ensures the continuity of the refrigerant during the input and output process, thereby ensuring that the movement of the refrigerant in the condensing chamber a is also continuous, thus guaranteeing the stability and uniformity of the cooling effect.

[0106] In this embodiment, a stop member 400 is also provided in the condensing chamber a. The stop member 400 is arranged in the input direction of the refrigerant inlet 201 to receive most of the refrigerant input from the refrigerant inlet 201.

[0107] When the refrigerant is introduced into the condensing chamber a through the refrigerant inlet 201, the rapid input speed and the vaporization of the refrigerant upon entering the condensing chamber a due to temperature changes, which generates a small amount of gas, result in a jet-like input pattern at the refrigerant inlet 201. This instability in the refrigerant input leads to the following: In this embodiment, a stop member 400 is provided in the jet direction to receive most of the jetted refrigerant, ensuring a stable and continuous input.

[0108] Preferably, in this embodiment, the stop member 400 is fixed to the inner cylinder 200 or the outer cylinder 100, and forms a liquid-blocking gap b between it and the outer wall of the inner cylinder 200.

[0109] Based on the above configuration, the stop member 400 can only receive the refrigerant from the injection section, but will not stop the refrigerant input from the refrigerant inlet 201, thus ensuring the input of the refrigerant.

[0110] In this embodiment, to ensure the connection between the liquid-blocking gap b and the condensation chamber a, so that the cold medium can be transported in the circumferential direction within the liquid-blocking gap b, the liquid-blocking space is open on both sides in the circumferential direction to accommodate the overflow of the cold medium.

[0111] Specific reference Figure 11As shown, the liquid-blocking component has fixed parts bent at both ends. These fixed parts are fixed to the outer wall of the inner cylinder 200 along the axial direction of the inner cylinder 200. The liquid-blocking component forms openings at both ends along the circumferential direction of the inner cylinder 200, thereby enabling the refrigerant to be output circumferentially and transported according to the set path.

[0112] In addition, in order to monitor the temperature inside the beverage container 700, a temperature controller is provided in this embodiment, and the temperature probe of the temperature controller extends into the ice-receiving area.

[0113] Specific reference Figure 2 As shown, in this embodiment, the thermostat 3 is installed on the outer cylinder 100 and fixed to the wall on the output side of the outer cylinder 100, so that the monitoring probe can monitor the temperature of the ice-collecting area; the tail of the thermostat 3 passes through the condensation area, and an installation sleeve can be set in the condensation area to pass the wire through the installation sleeve so that the thermostat 3 can be electrically connected to the circuit board on the side of the power component.

[0114] In this embodiment, by using the temperature probe of the temperature controller 3 to monitor the temperature of the ice-receiving area, the output efficiency of the power component can be changed by detecting the temperature. For example, when the temperature is higher than the threshold, the power component accelerates its rotation to increase the amount of ice shavings scraped; when it is lower than the threshold, the rotation speed is reduced to ensure the smoothness of the ice shavings remains stable.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
