Description

Technical Field

[0001] This application relates to the field of beverage preparation apparatus, and in particular to a cold drink container with temperature detection function. Background Technology

[0002] Cold drink equipment refers to devices specifically designed for cooling, storing, or preparing low-temperature beverages.

[0003] In related technologies, a cold drink device includes a housing and a cold drink container detachably installed in the housing. The cold drink container contains a refrigeration mechanism and a stirring mechanism. The refrigeration mechanism typically includes an evaporator coil disposed within the cavity of the cold drink container and a temperature detector for measuring the temperature of the evaporator coil. The stirring mechanism has a stirring scraper that is rotated and installed inside the cold drink container. When using the above-mentioned cold drink device, the refrigeration mechanism circulates, causing the evaporator coil to reach an extremely low temperature. Upon contact with the ultra-cold surface of the evaporator coil, the beverage instantly freezes. The high-speed rotating stirring scraper continuously scrapes off the ice layer formed on the evaporator coil, breaking it into fine ice crystals. When the temperature detector detects that the temperature of the evaporator coil has dropped to a set value, it transmits an electrical signal to the refrigeration system, causing the refrigeration mechanism to stop refrigeration.

[0004] Regarding the aforementioned technologies, the inventors believe that when using the above-mentioned cold drink device to prepare cold drinks, the temperature monitor only detects the temperature of the refrigeration mechanism, making it difficult to accurately detect the temperature of the cold drink. Utility Model Content

[0005] To improve the accuracy of temperature detectors in detecting the temperature of cold drinks, this application provides a cold drink container with temperature detection function.

[0006] The cold drink container with temperature detection function provided in this application adopts the following technical solution:

[0007] A cold drink container with temperature detection function includes a container shell with openings at the top and bottom, an evaporator arranged at the lower opening of the container shell, a stirring assembly rotatably arranged inside the container shell, and a container top cover for closing the upper opening of the container shell; the evaporator has a cooling shell, the inner side wall of the cooling shell has an evaporation coil arranged in close contact, and the lower end of the cooling shell has a mounting base that mates with the lower opening of the container shell; the container shell, the mounting base, and the container top cover cooperate to form a stirring chamber for the stirring assembly to rotate; the container shell has a temperature detector connected to the evaporator in the stirring chamber for detecting the temperature of the cold drink.

[0008] By adopting the above technical solution, when making cold drinks using a cold drink container, the operator first pours the beverage into the stirring chamber and seals the top of the container. The refrigeration mechanism circulates, making the temperature of the evaporator coil extremely low. The beverage freezes instantly upon contact with the surface of the cooling shell. The high-speed rotating stirring component continuously scrapes off the ice layer formed on the outer surface of the cooling shell and mixes it evenly with the liquid. When the temperature detector detects that the temperature of the cold drink has dropped to the set value, it transmits an electrical signal to the refrigeration mechanism. The refrigeration mechanism stops refrigeration, preventing the temperature of the evaporator coil from decreasing further, while the stirring component continues to rotate. By using a temperature detector to monitor the temperature of the cold drink in real time, and in conjunction with the evaporator, the effective control of the cold drink temperature is achieved, which helps to improve the accuracy of the temperature detector in detecting the temperature of the cold drink.

[0009] Optionally, the temperature detector is disposed at the bottom of the stirring chamber, and the mounting base has a mounting hole for arranging the temperature detector.

[0010] By adopting the above technical solution, the temperature detector is placed in the mounting base hole at the bottom of the stirring chamber, which enables the temperature detector to more accurately detect the temperature of the cold drink located at the bottom of the stirring chamber, and at the same time facilitates the installation and placement of the temperature detector.

[0011] Optionally, the temperature detector is provided with a first seal on one side of the top surface of the mounting base.

[0012] By adopting the above technical solution, a first sealing element is set on one side of the top surface of the mounting base, making it difficult for cold drinks to leak from the arrangement hole to the bottom of the mounting base. This helps to enhance the overall sealing of the cold drink container and further ensure the accuracy of the temperature detector in detecting the temperature of the cold drink.

[0013] Optionally, the lower end of the side wall of the container shell is provided with a discharge port and a discharge valve is provided at the discharge port for controlling the opening and closing of the discharge port. The temperature detector is arranged on the side of the mounting base away from the discharge port.

[0014] By adopting the above technical solution, placing the temperature detector on the side of the mounting base away from the discharge port can reduce the impact of the discharge operation on the temperature detection results, thereby helping to ensure the accuracy of temperature detection.

[0015] Optionally, the stirring assembly includes a rotating shaft and stirring blades mounted on the rotating shaft; the rotating shaft is arranged through the middle of the evaporator along an axis parallel to the container shell, and a second seal is provided on the top of the cooling shell.

[0016] By adopting the above technical solution, a stirring assembly consisting of a rotating shaft and stirring blades is used to stir cold drinks. The rotating shaft is arranged in a direction parallel to the axis of the container shell and passes through the middle of the evaporator to ensure uniform stirring. The second sealing element set on the top of the cooling shell of the rotating shaft helps to enhance the sealing of the stirring chamber and reduce the risk of cold drinks entering the evaporator.

[0017] Optionally, the stirring blade includes a mounting part sleeved on the top of the rotating shaft, three first scrapers with their upper ends connected to the mounting part and circumferentially spaced on the outside of the cooling shell, and three second scrapers connecting two adjacent first scrapers; one end of the second scraper is connected to the lower end of one of the first scrapers, and the other end of the second scraper is connected to the middle of another first scraper.

[0018] By adopting the above technical solution, the specific structure of the stirring blade is disclosed. The stirring blade is composed of the mounting part, the first scraper and the second scraper, which realizes multi-directional stirring of cold drinks, so that the cold drinks are fully mixed, which helps to improve the stirring efficiency. At the same time, it helps to scrape off the frost on the surface of the cooling shell, which helps to enhance the cooling effect of the evaporator on the cold drinks.

[0019] Optionally, the first scraper has a clearance groove at one end near the mounting base for accommodating a temperature detector.

[0020] By adopting the above technical solution, the setting of the clearance groove reduces the risk of interference between the first scraper and the temperature detector during rotation, ensuring the normal operation of the stirring assembly and the temperature detector.

[0021] Optionally, the first scraper has a first contact surface that conforms to the cooling housing arrangement, and the second scraper has a second contact surface that conforms to the cooling housing arrangement.

[0022] By adopting the above technical solution, the arrangement of the first and second bonding surfaces allows the first and second scrapers to better contact the cooling shell, thereby more effectively scraping off the frost or ice on the surface of the cooling shell, which helps to improve the heat exchange efficiency in the cold drink making process.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. A cold drink container with temperature detection function, comprising a container shell, an evaporator, a stirring assembly, and a container top cover; when making cold drinks using the cold drink container, the operator first pours the beverage into the stirring chamber and seals the container top cover. The refrigeration mechanism circulates, making the evaporator coil extremely cold. The beverage freezes instantly upon contact with the surface of the cooling shell. The high-speed rotating stirring assembly continuously scrapes off the ice layer formed on the outer surface of the cooling shell and mixes it evenly with the liquid. When the temperature detector detects that the temperature of the cold drink has dropped to a set value, it transmits an electrical signal to the refrigeration mechanism, which stops refrigeration, preventing the temperature of the evaporator coil from decreasing further, while the stirring assembly continues to rotate; by arranging the temperature detector on the mounting base, the temperature of the cold drink located at the bottom of the stirring chamber is detected, which helps to improve the accuracy of the temperature detector in detecting the temperature of the cold drink;

[0026] 3. The clearance groove reduces the risk of interference between the first scraper and the temperature detector during rotation, ensuring the normal operation of the stirring assembly and the temperature detector. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a cold drink container with temperature detection function. (See also...) Figure 1 and Figure 2 The cold drink container with temperature detection function includes a container shell 1 with openings at the top and bottom, an evaporator 2 arranged at the lower opening of the container shell 1, a stirring assembly 3 rotatably arranged inside the container shell 1, and a container top cover 4 for closing the upper opening of the container shell 1. A first sealing ring 41 is provided at the lower end of the container top cover 4 to seal against the upper opening of the container shell 1. A discharge port 11 is provided at the lower end of the side wall of the container shell 1. A discharge valve 12 for controlling the opening and closing of the discharge port 11 is provided on the outside of the container shell 1 and the discharge port 11.

[0035] Reference Figure 2 The evaporator 2 has a cooling shell 21, and the inner wall of the cooling shell 21 has evaporation coils 22 arranged in close fit. The lower end of the cooling shell 21 has a mounting base 23 that mates with the lower opening of the container shell 1. The cooling shell 21 can be made of a metal shell with good thermal conductivity, which can achieve efficient heat exchange. The mounting base 23 is integrally formed with the cooling shell 21, which is convenient for the operator to clean its surface after use. The outer edge of the mounting base 23 is provided with a second sealing ring 24 that seals with the lower opening of the container shell 1. The container shell 1, the mounting base 23 and the container top cover 4 cooperate to form a stirring chamber 5 for the stirring assembly 3 to be rotated.

[0036] Reference Figure 2 and Figure 3The container shell 1 and the stirring chamber 5 contain a temperature detector 6 connected to the evaporator 2 for detecting the temperature of the cold drink. The mounting base 23 has an arrangement hole 231 on the side away from the outlet 11 for accommodating the temperature detector 6. A first sealing element 61 is provided on the top surface of the temperature detector 6 to prevent the cold drink from leaking through the arrangement hole 231 to the bottom of the mounting base 23, thereby enhancing the overall sealing of the cold drink container. In this embodiment, the first sealing element 61 has a regular hexagonal cross-section along the length direction perpendicular to the temperature detector 6. A locking nut 62 is provided on the bottom surface of the temperature detector 6, and the locking nut 62 cooperates with the first sealing element 61 to achieve a sealed connection between the temperature detector 6 and the mounting base 23.

[0037] Reference Figure 2 and Figure 4 The stirring assembly 3 includes a rotating shaft 31 and stirring blades 32 mounted on the rotating shaft 31. The rotating shaft 31 is arranged through the middle of the evaporator 2 along an axis parallel to the container shell 1. A second seal 311 is provided between the rotating shaft 31 and the top of the cooling shell 21. In this embodiment, the lower end of the rotating shaft 31 is connected to the output end of the drive motor, enabling the drive motor to drive the stirring blades 32 to rotate at high speed within the stirring chamber 5. The second seal 311 can be a rubber sealing ring, making it difficult for beverages to enter the evaporator 2 from the top of the cooling shell 21.

[0038] Reference Figure 4 and Figure 5 The stirring blade 32 includes a mounting portion 321 sleeved on the top of the rotating shaft 31, a first scraper 322 whose upper end is connected to the mounting portion 321 and is circumferentially spaced on the outer side of the cooling shell 21, and a second scraper 323 connecting two adjacent first scrapers 322. One end of the second scraper 323 is connected to the lower end of the first scraper 322, and the other end is connected to the middle of the first scraper 322. The first scraper 322 has a first contact surface 3221 that conforms to the cooling shell 21. The second scraper 323 has a second contact surface 3231 that conforms to the cooling shell 21. A clearance groove 3222 for accommodating the temperature detector 6 is formed on the bottom end of one side of the first scraper 322, reducing the risk of interference between the first scraper 322 and the temperature detector 6 when the stirring blade 32 rotates at high speed. In this embodiment, the second scraper 323 is an arc-shaped scraper.

[0039] The implementation principle of a cold drink container with temperature detection function in this application embodiment is as follows: When making cold drinks using the cold drink container, the operator first pours the beverage into the stirring chamber 5 and seals the container top cover 4. The refrigeration mechanism located outside the cold drink container circulates, making the temperature of the evaporation coil 22 of the evaporator 2 extremely low. When the beverage comes into contact with the surface of the cooling shell 21, it will freeze instantly. The high-speed rotating stirring component 3 can continuously scrape off the ice layer formed on the outer surface of the cooling shell 21 and mix it evenly with the liquid. When the temperature detector 6 detects that the temperature of the cold drink has dropped to the set value, it will transmit an electrical signal to the refrigeration mechanism. The refrigeration mechanism stops refrigeration, so that the temperature of the evaporation coil 22 no longer drops, while the stirring component 3 continues to rotate. Placing the temperature monitor on the side of the mounting base 23 away from the outlet 11 helps to improve the accuracy of the temperature detector 6 in detecting the temperature of the cold drink.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
