[0001] The present application relates to the technical field of coffee machine equipment, and in particular to an aerating device and coffee machine. BACKGROUND

[0002] With the improvement of people's living standards, the taste of drinks is also high, and the addition of nitrogen and cold extraction in liquid at the same time can improve the taste of ice-bubble water. At present, there is a lack of small household appliances that can simultaneously cool and add nitrogen on the market, and most of the existing devices need to use a refrigeration box for cooling, which takes a long time to cool, and then high-pressure nitrogen is filled in. In the process of injecting high-pressure nitrogen, heat is easily absorbed, which affects the cold extraction effect, and the effect of dissolving nitrogen in liquid at low temperature is good.

[0003] For example, the extraction equipment for nitrogen-containing beverages disclosed in the Chinese utility model patent with the announcement number CN207804057U includes a pressure barrel, a first pipeline, a second pipeline, a discharger and a refrigeration unit. An additional refrigeration unit is needed for cooling, and the original material filter bag needs to be taken out after extraction for secondary pressure compensation, which is complicated and dangerous to operate. The pressure barrel also needs to be placed in the refrigeration unit, which is complicated to operate and takes a long time to cool.

[0032] The above and other aspects, features and advantages of the present application will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:

[0033] Specific embodiments of the present application are described hereinafter, by way of non-limiting example; however, it is to be understood that the application is not limited to the particular embodiments described, as such can be carried out in various ways. Well-known and / or redundant functions and structures are not described in detail to avoid obscuring the present application unnecessarily.

[0034] The specification can use phrases such as "in one embodiment", "in another embodiment", "in yet another embodiment", or "in other embodiments", which can refer to one or more of the same or different embodiments of the application.

[0035] The present application provides an aerator, as shown in FIG. 1 and FIG. 2, which comprises a water tank 5, an evaporation pipe 7, a water pump 8, a water outlet valve 4 and a gas tank 2.

[0036] As shown in FIG. 3, the water tank 5 comprises a first cavity 51 and a second cavity 52 surrounding the first cavity 51. Specifically, a partition plate 53 is arranged in the water tank 5, which divides the water tank 5 into the first cavity 51 and the second cavity 52.

[0037] As shown in FIG. 1 and FIG. 3, the first cavity 51 is provided with a first water inlet 54 connected with the water outlet 56 of the water pump 8, an air inlet 55 connected with the air tank 2, and a water outlet 56 connected with the water inlet of the water outlet valve 4. The second cavity 52 is provided with a second water inlet 57 and a water inlet 58 connected with the water inlet of the water pump 8, and water is added into the second cavity 52 through the second water inlet 57. The second water inlet 57 is a port (not shown in the drawings) communicating with the second cavity 52.

[0038] The partition plate 53 arranged in the water tank 5 can be in a cylindrical shape, the first cavity 51 is formed in the cylinder, and the second cavity 52 is formed outside the cylinder. The tank body of the water tank 5 can also be in a cylindrical shape, and the axis of the tank body and the axis of the partition plate 53 are collinear, so that the first cavity 51 is located in the middle of the water tank 5, and the second cavity 52 is formed.

[0039] The partition plate 53 arranged in the water tank 5 not only clearly divides the first cavity 51 and the second cavity 52, but also realizes the orderly flow and distribution of the liquid in the water tank 5 through reasonable pipeline design, thereby improving the working efficiency of the device and the liquid treatment effect.

[0040] As shown in FIG. 1 and FIG. 3, one end of the evaporation pipe 7 is connected with the compressor assembly 6, and the other end extends into the second cavity 52 for absorbing the heat of the liquid in the second cavity 52, so as to reduce the temperature of the liquid in the second cavity 52.

[0041] Specifically, the end of the evaporation pipe 7 extending into the second cavity 52 surrounds the outer wall of the first cavity 51. The end of the evaporation pipe 7 in the second cavity 52 surrounds the outer wall of the first cavity 51, which can more effectively utilize the heat absorption area of the evaporation pipe 7, accelerate the cooling process of the liquid, and improve the cooling efficiency.

[0042] Further, the evaporation pipe 7 is in a spiral structure to prolong the length of the evaporation pipe 7 in the second cavity 52. In addition, the evaporation pipe 7 can be arranged in contact with the outer wall of the first cavity 51. The evaporation pipe 7 in the spiral structure is in contact with the outer wall of the first cavity 51, which increases the heat exchange area and improves the heat exchange efficiency, and can simultaneously ensure the temperature of the liquid in the first cavity 51 and the second cavity 52.

[0043] The compressor assembly 6 is combined with the evaporation pipe 7 in the present application, so that the evaporation pipe 7 is directly immersed in the liquid in the second cavity 52 to quickly cool. The water tank 5 is provided with the first cavity 51, and the liquid ready for drinking can be transported from the second cavity 52 to the first cavity 51 by the water pump 8. The outer wall of the first cavity 51 is contacted by the evaporation pipe 7, so that the liquid ready for drinking can be subjected to secondary heat preservation, and the loss of cold energy is reduced.

[0044] As shown in FIG. 1, the water pump 8 is connected with the water tank 5 for conveying the liquid in the second cavity 52 into the first cavity 51. The water outlet valve 4 is communicated with the first cavity 51.

[0045] The gas outlet 21 of the gas tank 2 is connected with the first cavity 51 for sending the nitrogen in the gas tank 2 into the first cavity 51, so that the liquid in the first cavity 51 is conveyed to the water outlet valve 4 under the action of the nitrogen. The gas outlet 21 is also connected with the water outlet valve 4 for mixing the nitrogen with the liquid in the water outlet valve 4. The liquid is mixed with the nitrogen at high pressure in the present application, and the temperature in the water tank 5 is reduced through the evaporation pipe 7, so that the finally output liquid has better taste and temperature, and the compressed nitrogen is output as kinetic energy, which greatly reduces the residual liquid in the pipeline through which the liquid flows, and is beneficial to keeping the pipeline clean.

[0046] As shown in FIG. 1, the gas outlet 21 of the gas tank 2 is connected with the gas inlet 55 of the first cavity 51 through the first gas path 91, and is also connected with the gas inlet 55 of the water outlet valve 4 through the second gas path 92. By arranging the first gas path 91 and the second gas path 92, the flow direction and distribution of the nitrogen can be more flexibly controlled, the mixing of the nitrogen and the liquid in the first cavity 51 and the water outlet valve 4 is ensured, and the mixing effect and the use performance of the device are improved.

[0047] In addition, as shown in FIG. 1, the gas filling device can also include a main gas path 90 and an electromagnetic valve assembly 3. One end of the main gas path 90 is connected with the gas outlet 21 of the gas tank 2, and the electromagnetic valve assembly 3 includes an inlet end 31 and two outlet ends 32.

[0048] The inlet end 31 is connected with the other end of the main gas path 90, and the two outlet ends 32 are respectively connected with the first gas path 91 and the second gas path 92. The addition of the main gas path 90 and the electromagnetic valve assembly 3 provides a more precise and controllable nitrogen supply system for the gas filling device. The precise control of the nitrogen flow can be realized through the adjustment of the electromagnetic valve assembly 3, and the working efficiency and stability of the device are further improved.

[0049] As shown in FIG. 1, the gas filling device also includes a gas pump 1 connected with the gas tank 2 for compressing the nitrogen and conveying it into the gas tank 2. The arrangement of the gas pump 1 enables the gas filling device to autonomously compress the nitrogen and convey it into the gas tank 2, reduces the dependence on external nitrogen source, and improves the self-sufficiency and use convenience of the device.

[0050] The water path and the gas path are connected through the gas pump 1, the compressor, the water tank 5, the water pump 8 and the electromagnetic valve assembly 3, so that one-key simple operation for brewing and cleaning the pipeline can be realized. The gas pump 1 and the gas tank 2 can freely adjust the pressure, so that the extraction flavor under different pressures can be realized.

[0051] In use, the evaporating pipe 7 is welded with the compressor assembly 6 to become a refrigeration module, and the other end of the evaporating pipe 7 is coiled into the inside of the liquid tank 5 filled with liquid water, and the evaporating pipe 7 absorbs heat through the operation of the compressor assembly 6 to reduce the temperature of the liquid in the second cavity 52 to the required temperature, and the liquid in the second cavity 52 is transported to the first cavity 51 for storage and heat preservation by the water pump 8.

[0052] The compressed nitrogen in the gas tank 2 is released to the gas inlet 55 of the first cavity 51 and the gas inlet 55 of the water outlet valve 4 through the opening of the two outlet ends 32 of the electromagnetic valve assembly 3 when the compressed nitrogen in the gas tank 2 reaches the required pressure, and the kinetic energy of the compressed nitrogen transports the liquid in the first cavity 51 to the water inlet of the water outlet valve 4, and the liquid in the water outlet valve 4 is mixed with the nitrogen transported by one of the outlet ends 32 to produce a rolling and mixing effect, and the finally output liquid has abundant rolling and mixing ice-slush bubble effect.

[0053] At the same time, because the compressed nitrogen (or the gas pump 1) is used as the kinetic energy output, unlike the liquid output by the water pump 8, the residual liquid in the pipeline can be greatly reduced, which is beneficial to reduce the pipeline blockage and avoid the influence of the residual liquid on the quality of the second cup of beverage.

[0054] The embodiment of the application also provides a coffee machine, which comprises a coffee machine body and the gas filling device as described above. The gas filling device is integrated into the coffee machine, which can provide an innovative nitrogen and liquid mixing technology for the coffee machine and increase the functional diversity of the coffee machine.

[0055] The above embodiments are only exemplary embodiments of the application and are not used to limit the application, and the protection scope of the application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the application within the spirit and protection scope of the application, and the modification or equivalent replacement is also regarded as falling within the protection scope of the application.
