Description

Technical Field

[0001] This invention relates to the field of food preparation technology, and in particular to an evaporator and a cold drink preparation machine. Background Technology

[0002] In daily life, people often want to drink cold drinks to cool off in the hot summer. They often use cold drink makers to make cold drinks. Liquid drinks such as water, juice or sugar water are placed into the container of the cold drink maker. The cooling element in the evaporator absorbs heat and lowers the temperature of the liquid drink, causing it to solidify into ice or snow. Then, a stirrer is used to stir the mixture, breaking the ice into sand or melting the snow into slush, thus making the liquid drink into slush or slush.

[0003] In existing technology, the evaporator is located inside the container to allow the cooling components in the evaporator to absorb heat and lower the temperature of the liquid beverage inside the container. However, when cleaning the container after making cold drinks, it needs to be removed. Cold drinks adhering to the evaporator drip or flow into the cleaning dead corners between the evaporator and the machine body, making it difficult to thoroughly clean the cold drink maker. Moreover, the evaporator is at a low temperature when it has just stopped running. If the user forcibly puts their hand into the cleaning dead corners, their skin is likely to come into contact with the low-temperature evaporator surface, which can easily cause skin irritation or peeling. At the same time, the skin will be covered with sticky cold drinks, reducing the user experience.

[0004] Therefore, there is an urgent need for an evaporator and a cold drink preparation machine to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an evaporator and a cold drink preparation machine that can prevent cold drinks adhering to the evaporator from dripping or flowing into the cleaning dead corner between the evaporator and the body of the cold drink preparation machine.

[0024] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or 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.

[0026] In the description of this invention, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] A cold drink preparation machine is a refrigeration and stirring device used to turn liquid beverages into semi-solid slushies or slushies. A cold drink preparation machine typically consists of a compressor refrigeration system, a stirring motor, an evaporator, a mixing drum, a stirrer, and a temperature control device. The mixing drum holds the liquid beverage, the compressor compresses and refrigerates it so that the evaporator can absorb the temperature of the liquid beverage contained in the mixing drum and solidify it into ice or snow, the stirrer breaks up the ice into slushies or melts the snow into slushies, and the temperature control device regulates the temperature inside the mixing chamber.

[0028] The evaporator of a cold drink preparation machine is located inside the container to allow the cooling components in the evaporator to absorb heat and lower the temperature of the liquid beverage inside the container. When making cold drinks and cleaning the container is required, the container needs to be removed. Cold drinks adhering to the evaporator drip or flow into the cleaning dead corner between the evaporator and the machine body, making it difficult to thoroughly clean the cold drink preparation machine. The evaporator provided by this invention can directly serve as a container to hold liquid beverages. When the container is removed from the machine body, the residual cold drinks adhering to the evaporator can collect inside the evaporator chamber, preventing cold drinks from dripping or flowing into the cleaning dead corner between the evaporator and the machine body.

[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0030] Figure 1 A schematic diagram of the evaporator provided in Embodiment 1 is shown. Figure 4 A schematic diagram of the evaporator provided in Embodiment 2 is shown. Figure 7 A schematic diagram of the evaporator provided in Embodiment 3 is shown. Figure 10 A schematic diagram of the cold drink preparation machine provided in Embodiment 4 is shown; Figure 13 A schematic diagram of the cold drink preparation machine provided in Embodiment 5 is shown.

[0031] like Figure 1 , Figure 4 , Figure 7 , Figure 10 and Figure 13 As shown, the present invention provides an evaporator connected to the feed cover 200 of a cold drink preparation machine. The evaporator includes a cylinder 1 and a cooling component 2. A first chamber 11 is provided inside the cylinder 1, and a first opening 12 for communicating with the outside world and the first chamber 11 is provided on the peripheral side wall of the cylinder 1. The cooling component 2 is installed on the cylinder 1. The first opening 12 is horizontally upward.

[0032] When the evaporator provided by this invention is installed on the body 100 of the cold drink maker, the user can put liquid beverages into the first chamber 11 through the first opening 12. The refrigeration component 2 refrigerates and exchanges heat with the liquid beverages in the first chamber 11, thereby causing the liquid beverages to solidify into ice or snow. After the cold drink maker prepares the cold drink, even if the cold drink in the first chamber 11 melts, it will collect at the bottom of the first chamber 11 and will not drip or flow between the evaporator and the body 100. There will be no cleaning dead corners that are difficult for users to clean, reducing the cleaning difficulty of the cold drink maker and improving the user experience.

[0033] Preferably, the first opening 12 is located at the junction of the evaporator and the material cover 200, so that the first chamber 11 of the cylinder 1 and the internal space of the material cover 200 can be spliced ​​together to form a container space for accommodating liquid beverages, thereby accommodating more liquid beverages.

[0034] Preferably, the width of the projection of the first opening 12 in the vertical direction is the same as the width of the cylinder 1, and the length of the projection of the first opening 12 in the vertical direction is the same as the length of the cylinder 1, so as to maximize the area of ​​the first opening 12 so that the liquid beverage can enter the first chamber 11.

[0035] It should be noted that the specific type of the refrigeration component 2 in this invention is not limited here. The refrigeration component 2 can be a heat exchange channel, a heat exchange tube, or a semiconductor refrigeration chip. Those skilled in the art can reasonably set it according to actual needs.

[0036] The specific shape of the evaporator cylinder 1 in this invention is not limited here. It can be U-shaped, semi-circular, arc-shaped, or even cylindrical. As long as the cylinder 1 has a first chamber 11, after the liquid beverage is put into the first chamber 11, the liquid beverage can be cooled down, and the melted cold beverage can be collected at the bottom of the first chamber 11 without flowing out of the first chamber 11.

[0037] Continue as Figure 1 , Figure 4 , Figure 7 , Figure 10 and Figure 13As shown, the present invention also provides a cold drink preparation machine, including a body 100 and an evaporator. The evaporator is installed on the body 100, thereby eliminating cleaning dead corners in the cold drink preparation machine, reducing the difficulty of cleaning the cold drink preparation machine, and improving the user experience.

[0038] Figure 11 A cross-sectional schematic diagram of the cold drink preparation machine provided in Embodiment 4 is shown. Figure 12 An exploded view of the cold drink preparation machine provided in Embodiment 4 is shown. Figure 14 A cross-sectional schematic diagram of the cold drink preparation machine provided in Embodiment 5 is shown. Figure 15 An exploded view of the cold drink preparation machine provided in Embodiment 5 is shown. Figure 1 , Figure 4 , Figure 7 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, the cold drink preparation machine also includes a material cover 200, which is detachably connected to the machine body 100. A second chamber 201 is provided inside the material cover 200. The material cover 200 has a feeding port 202 for connecting the second chamber 201 to the outside. The feeding port 202 faces upward. When the material cover 200 is connected to the machine body 100, the first chamber 11 and the second chamber 201 form a material cavity. Thus, when using the cold drink preparation machine, the liquid beverage in the material cavity can be observed through the feeding port 202, preventing the stirrer 300 from being frozen by ice and stuck for a long time, which could lead to the stirrer 300 breaking or the motor becoming blocked. When the first chamber 11 and the second chamber 201 form a material cavity, the material cavity replaces the first chamber 11 as the container for holding the liquid beverage. The evaporator's cooling element 2 can directly absorb heat and lower the temperature of the liquid beverage in the material cavity.

[0039] Preferably, the first chamber 11 is located below the second chamber 201, so that the entire refrigeration unit 2 can be located below the liquid surface of the liquid beverage in the material chamber, thereby improving the refrigeration efficiency of the refrigeration unit 2.

[0040] It should be noted that the evaporator is also equipped with a stirrer inlet / outlet 16. After the evaporator is installed into the body 100 of the cold drink preparation machine, the stirrer 300 needs to extend into the first chamber 11 to stir the liquid beverage in the first chamber 11 or the material chamber. It should also be noted that after the evaporator is installed into the body 100 of the cold drink preparation machine, the evaporator is enclosed as a semi-closed container with only the first opening 12 to prevent the liquid beverage from flowing out of the first chamber 11 through the stirrer inlet / outlet 16.

[0041] like Figures 10 to 15As shown, the cold drink preparation machine also includes a sealing element 400, which is disposed between the evaporator and the material cover 200 to prevent liquid beverage from flowing out of the material chamber from the joint between the evaporator and the material cover 200 during the preparation of cold drinks. Specifically, the sealing element 400 is a sealing ring or a sealing strip. Those skilled in the art can reasonably set the sealing element 400 according to the actual sealing requirements of the cold drink preparation machine, which will not be elaborated here.

[0042] Continue as Figures 10 to 15 As shown, the material cover 200 includes a first material shell 203 and a second material shell 204 that are nested together with inner and outer seals. A heat insulation structure is provided between the first material shell 203 and the second material shell 204. In the process of making cold drinks using the cold drink making machine, the heat insulation structure can prevent the heat from the external environment from being conducted to the material cavity through the material cover 200, thereby improving the efficiency of the cold drink making machine in making cold drinks.

[0043] Specifically, the insulation structure is an insulation cavity 205, which is filled with insulation material. It should be noted that the specific type of insulation material is not limited here. It can be PP (polypropylene) foam board, mineral wool or glass wool. Those skilled in the art can make reasonable selections according to actual needs and fill the insulation material into the insulation cavity 205 set between the first shell 203 and the second shell 204. As long as the insulation material is non-toxic and has insulation function, it is acceptable. Further details will not be elaborated here.

[0044] It should be noted that the cold drink preparation machine provided by the present invention can not only add liquid beverages such as water, fruit juice or sugar water into the material chamber when preparing cold drinks, but also add fillings such as fruits, grains or biscuits into the material chamber at the same time to enhance the flavor of the cold drinks prepared by the cold drink preparation machine. The stirrer 300 can not only break ice into sand or melt snow into mud, but also crush the fillings so that the fillings can be mixed with the liquid beverages.

[0045] Example 1 Figure 2 A cross-sectional schematic diagram of the evaporator provided in this embodiment is shown. Figure 3 An exploded view of the evaporator provided in this embodiment is shown. Figures 1 to 3 As shown, the evaporator is connected to the material cover 200 of the cold drink preparation machine. The evaporator includes a cylinder 1 and a refrigeration component 2. A first chamber 11 is provided inside the cylinder 1, and a first opening 12 is provided on the peripheral wall of the cylinder 1 to connect the outside to the first chamber 11. The refrigeration component 2 is installed on the cylinder 1. Several heat exchange channels 21 are provided inside the cylinder 1, and a first refrigerant inlet 22 and a first refrigerant outlet 23 are provided on the cylinder 1, respectively communicating with the heat exchange channels 21.

[0046] Preferably, several heat exchange channels 21 are connected end to end in sequence, the first refrigerant inlet 22 is connected to the first heat exchange channel 21, and the first refrigerant outlet 23 is connected to the last heat exchange channel 21, thereby extending the flow path of the refrigerant in the heat exchange channel 21 and thus improving the heat exchange efficiency of the refrigeration component 2.

[0047] In some embodiments, a heat exchange channel 21 is provided inside the cylinder 1, and the first refrigerant inlet 22 and the first refrigerant outlet 23 are respectively connected to the heat exchange channel 21, thereby forming a single-path heat exchange channel 21 and simplifying the structure of the heat exchange channel 21. It should be noted that the specific structure of the heat exchange channel 21 is not limited here, and those skilled in the art can reasonably set it according to actual needs, which will not be described in detail here.

[0048] When the evaporator provided in this embodiment is installed on the body 100 of the cold drink maker, the user can put liquid beverages into the first chamber 11 through the first opening 12, and then introduce refrigerant into the heat exchange channel 21 through the first refrigerant inlet 22. After the refrigerant exchanges heat with the liquid beverage in the first chamber 11, it flows out from the first refrigerant outlet 23. The liquid beverage in the first chamber 11 freezes into ice or snow. After the cold drink maker prepares the cold drink, even if the cold drink in the first chamber 11 melts, it will gather at the bottom of the first chamber 11 and will not drip or flow between the evaporator and the body 100, thus eliminating cleaning dead corners that are difficult for users to clean, reducing the cleaning difficulty of the cold drink maker, improving the user experience, simplifying the structure of the refrigeration component 2, making the evaporator more compact, and allowing the refrigerant charged into the heat exchange channel 21 to be as close as possible to the first chamber 11, thereby improving the heat exchange efficiency and thus improving the cooling efficiency of the heat exchange channel 21.

[0049] Specifically, the cylinder 1 includes an inner shell 13 and an outer shell 14. One or more first heat exchange grooves 131 are formed on the side wall of the inner shell 13 near the outer shell 14, and / or one or more second heat exchange grooves 141 are formed on the side wall of the outer shell 14 near the inner shell 13. The first heat exchange grooves 131 and / or the second heat exchange grooves 141 form one or more heat exchange channels 21, thereby enabling the cylinder 1 with heat exchange channels 21 to be processed separately, reducing the molding difficulty of the cylinder 1.

[0050] It should be noted that when only one or more first heat exchange grooves 131 are provided on the side wall of the inner shell 13 near the outer shell 14, and no second heat exchange grooves 141 are provided on the side wall of the outer shell 14 near the inner shell 13, the first heat exchange grooves 131 and the side wall of the outer shell 14 near the inner shell 13 form a heat exchange channel 21; when only one first heat exchange groove 131 is not provided on the side wall of the inner shell 13 near the outer shell 14, and one or more second heat exchange grooves 141 are provided on the side wall of the outer shell 14 near the inner shell 13, the second heat exchange grooves 141 and the side wall of the inner shell 13 near the outer shell 14 form a heat exchange channel 21.

[0051] It should be noted that the connection between the inner shell 13 and the outer shell 14 is not limited here. They can be fixedly connected by welding, bonding or using fasteners (such as bolts). Those skilled in the art can set it reasonably according to the actual needs of the evaporator, and it will not be described in detail here.

[0052] It should be noted that in this embodiment, the heat exchange channel 21 acts as a cooling component 2, which can absorb the heat of the liquid beverage in the first chamber 11 and reduce the temperature of the liquid beverage. That is, the cooling component 2 is integrally formed with the cylinder 1.

[0053] It should be noted that the specific type of refrigerant provided in this embodiment is not limited here. It can be refrigerant such as dichlorofluoromethane, tetrafluoroethane or difluoromethane. Those skilled in the art can set it reasonably according to actual needs, and it will not be described in detail here.

[0054] It should be noted that the cylinder 1 in this embodiment is U-shaped, thus having a larger volume first chamber 11. In some embodiments, the cylinder 1 may also be cylindrical, semi-circular, or arc-shaped. Those skilled in the art can reasonably select the shape of the cylinder 1 according to the cooling method of the cooling component 2 in this embodiment.

[0055] Example 2 This embodiment provides an evaporator whose specific structure of the cylinder 1 is basically the same as that of Embodiment 1, the only difference being the installation principle of the refrigeration component 2.

[0056] Figure 5 A cross-sectional schematic diagram of the evaporator provided in this embodiment is shown. Figure 6 An exploded view of the evaporator provided in this embodiment is shown. Figures 4 to 6As shown, this embodiment provides an evaporator connected to the material cover 200 of a cold drink preparation machine. The evaporator includes a cylinder 1 and a refrigeration component 2. The cylinder 1 has a first chamber 11, and its peripheral sidewall has a first opening 12 for connecting the outside to the first chamber 11. The refrigeration component 2 is installed on the cylinder 1. The refrigeration component 2 has a heat exchange chamber 24 inside, and a second refrigerant inlet 25 and a second refrigerant outlet 26 for connecting the heat exchange chamber 24 to the outside.

[0057] When the evaporator provided in this embodiment is installed on the body 100 of the cold drink maker, the user can put liquid beverages into the first chamber 11 through the first opening 12, and then introduce refrigerant into the heat exchange chamber 24 through the second refrigerant inlet 25. After the refrigerant exchanges heat with the liquid beverage in the first chamber 11 in the heat exchange chamber 24, it flows out from the second refrigerant outlet 26. The liquid beverage in the first chamber 11 solidifies into ice or snow. After the cold drink maker prepares the cold drink, even if the cold drink in the first chamber 11 melts, it will collect at the bottom of the first chamber 11 and will not drip or flow between the evaporator and the body 100, thus eliminating the cleaning dead corners that are difficult for users to clean, reducing the cleaning difficulty of the cold drink maker, improving the user experience, and at the same time, it can make the refrigeration component 2 set independently of the cylinder 1. When the refrigeration component 2 fails, only the refrigeration component 2 can be replaced without replacing the entire evaporator, reducing the maintenance cost of the evaporator.

[0058] Specifically, the refrigeration component 2 includes several refrigeration pipes 27 connected end to end, thereby extending the flow path of the refrigerant within the receiving cavity 15 to improve the heat exchange efficiency of the refrigerant and thus enhance the refrigeration efficiency of the refrigeration component 2. It should be noted that the heat exchange cavity 24 is the internal channel of the refrigeration pipes 27.

[0059] Preferably, the inlet of the first refrigerant pipe 27 is the second refrigerant inlet 25, and the outlet of the last refrigerant pipe 27 is the second refrigerant outlet 26. This allows the refrigerant pipe 27 to be set up completely independently from the cylinder 1. If the refrigerant pipe 27 leaks and is damaged, only the refrigerant pipe 27 can be replaced without replacing the entire evaporator, thus reducing the maintenance cost of the evaporator.

[0060] In some embodiments, the refrigeration component 2 includes a refrigeration pipe 27, the inlet of which is a second refrigerant inlet 25, and the outlet of which is a second refrigerant outlet 26.

[0061] Continue as Figures 4 to 6 As shown, several refrigeration pipes 27 extend in parallel directions and are arranged continuously or at intervals along the length of the cylinder 1, so as to arrange as many refrigeration pipes 27 as possible in the heat exchange chamber 24, and to extend the flow path of the refrigerant in the receiving chamber 15 as much as possible, so as to improve the heat exchange efficiency of the refrigerant and thus improve the refrigeration efficiency of the refrigeration component 2.

[0062] Continue as Figures 4 to 6 As shown, the cylinder 1 includes an inner shell 13 and an outer shell 14. A receiving cavity 15 is provided between the inner shell 13 and the outer shell 14. A first chamber 11 is opened on the side of the inner shell 13 away from the outer shell 14. The refrigeration component 2 is disposed in the receiving cavity 15. On the one hand, this allows the refrigeration component 2 to directly contact the inner shell 13, thereby improving the heat exchange efficiency with the liquid beverage in the first chamber 11 and improving the refrigeration efficiency. On the other hand, this allows the refrigeration component 2 to be housed in the receiving cavity 15, preventing the refrigeration component 2 from being exposed and preventing users from being frostbitten when their limbs come into contact with the refrigeration component 2 while cleaning the evaporator. It also improves the aesthetics of the evaporator and enhances the user experience of using the cold drink maker to prepare cold drinks.

[0063] Preferably, the evaporator further includes a heat-conducting element that fills the receiving cavity 15, allowing the heat from the liquid beverage in the first chamber 11 to be quickly transferred to the cooling element 2. The cooling element 2 absorbs the heat and rapidly lowers the temperature of the liquid beverage in the first chamber 11, thereby improving the cooling efficiency of the cooling element 2. It should be noted that the specific type of heat-conducting element is not limited here; it can be heat-conducting oil or heat-conducting silicone grease. When the heat-conducting element is heat-conducting oil, it is liquid and fills the receiving cavity 15; when the heat-conducting element is heat-conducting silicone grease, it is solid and fills the receiving cavity 15.

[0064] Preferably, the inner shell 13 is further provided with several third heat exchange grooves on the side wall near the receiving cavity 15, thereby increasing the heat dissipation area of ​​the liquid beverage in the first chamber 11 and improving the cooling efficiency of the refrigeration unit 2. It should be noted that the extension direction of the third heat exchange grooves is not limited here. They can extend along the length direction of the cylinder 1, along the width direction of the cylinder 1, or at an angle to the length direction of the cylinder 1, as long as they can increase the heat dissipation area of ​​the liquid beverage in the first chamber 11.

[0065] It should be noted that the cylinder 1 in this embodiment is U-shaped, thus having a larger volume first chamber 11. In some embodiments, the cylinder 1 may also be cylindrical, semi-circular, or arc-shaped. Those skilled in the art can reasonably select the shape of the cylinder 1 according to the cooling method of the cooling component 2 in this embodiment.

[0066] Example 3 This embodiment provides an evaporator whose specific structure of the cylinder 1 is basically the same as that of Embodiment 1 and Embodiment 2, and whose installation principle of the refrigeration component 2 is basically the same as that of Embodiment 2. The only difference is that the arrangement direction of the refrigeration pipe 27 is different.

Figures 7 to 9As shown, this embodiment provides an evaporator in which several refrigeration pipes 27 extend in parallel directions and are continuously or spaced along the width direction of the cylinder 1, thereby arranging as many refrigeration pipes 27 as possible in the heat exchange chamber 24 and extending the flow path of the refrigerant in the receiving chamber 15 as much as possible, so as to improve the heat exchange efficiency of the refrigerant and thus improve the refrigeration efficiency of the refrigeration component 2.

[0068] It should be noted that the cylinder 1 in this embodiment is U-shaped, thus having a larger volume first chamber 11. In some embodiments, the cylinder 1 may also be cylindrical, semi-circular, or arc-shaped. Those skilled in the art can reasonably select the shape of the cylinder 1 according to the cooling method of the cooling component 2 in this embodiment.

[0069] Example 4 like Figure 1 , Figure 4 , Figure 7 , Figure 10 , Figure 11 and Figure 12 As shown, the cold drink preparation machine also includes a material cover 200, which is detachably connected to the machine body 100. A second chamber 201 is provided inside the material cover 200. The material cover 200 has a feeding port 202 for connecting the second chamber 201 to the outside. The feeding port 202 faces upward. When the material cover 200 is connected to the machine body 100, the evaporator is at least partially located outside the second chamber 201. The first chamber 11 and the second chamber 201 surround to form a material cavity. Thus, when using the cold drink preparation machine, the liquid beverage in the material cavity can be observed through the feeding port 202, preventing the stirrer 300 from being frozen by ice and stuck for a long time, which could lead to the stirrer 300 breaking or the motor becoming blocked. When the first chamber 11 and the second chamber 201 surround to form a material cavity, the material cavity replaces the first chamber 11 as the container for holding the liquid beverage. The cooling element 2 of the evaporator can directly absorb heat and reduce the temperature of the liquid beverage in the material cavity.

[0070] In the cold drink preparation machine provided in this embodiment, the evaporator is at least partially located outside the second chamber 201, so that the evaporator and the material cover 200 are assembled together as two separate parts to form the material chamber, thereby reducing the volume of the cold drink preparation machine.

[0071] Example 5 This embodiment provides a cold drink preparation machine, whose cold drink preparation principle is basically the same as that of the cold drink preparation machine provided in Embodiment 4. The difference lies in the principle of the evaporator and the cover 200 being spliced ​​together to form the material cavity.

[0072] like Figure 1 , Figure 4 , Figure 7 , Figure 13 , Figure 14 and Figure 15As shown, the cold drink preparation machine also includes a material cover 200, which is detachably connected to the machine body 100. A second chamber 201 is provided inside the material cover 200. The material cover 200 has a feeding port 202 for connecting the second chamber 201 to the outside. The feeding port 202 faces upward. When the material cover 200 is connected to the machine body 100, the evaporator is located in the second chamber 201. The first chamber 11 and the second chamber 201 surround to form a material cavity. Thus, when using the cold drink preparation machine, the liquid beverage in the material cavity can be observed through the feeding port 202, preventing the stirrer 300 from being frozen by ice and stuck for a long time, which could lead to the stirrer 300 breaking or the motor becoming blocked. When the first chamber 11 and the second chamber 201 surround to form a material cavity, the material cavity replaces the first chamber 11 as the container for holding the liquid beverage. The cooling element 2 of the evaporator can directly absorb heat and reduce the temperature of the liquid beverage in the material cavity.

[0073] The evaporator provided in this embodiment is located in the second chamber 201 and serves as part of the material cover 200. It is spliced ​​with the space inside the material cover 200 to form a material cavity, preventing poor sealing at the joint between the evaporator and the material cover 200, which would cause liquid beverages to flow out of the material cover 200 through the joint between the evaporator and the material cover 200.
