[0058] Further, the fixed assembly 23 is a fixed seat, and the third connecting arm is movably connected with the fixed seat.

[0059] In the specific implementation process of the embodiment 1, as shown in the figure, Figure 5 The extraction mechanism 3 includes a pressure piece, and the pressure piece is connected with the powder bin 4.

[0060] More specifically, the extraction mechanism 3 includes a pressure piece, and the pressure piece is arranged on the shell assembly 1, and the pressure piece is connected with the powder bin 4 through a line. The pressure piece can exert pressure on the liquid in the powder bin 4.

[0061] In the specific implementation process of the embodiment 1, as shown in the figure, Figure 5 The extraction mechanism 3 further includes an ultrasonic piece, and the ultrasonic piece is connected with the powder bin 4.

[0062] More specifically, the ultrasonic component is connected to the coffee powder container 4 and sonicates the liquid inside, enabling better extraction of the coffee powder. Ultrasonic cavitation effect: When ultrasound propagates in a liquid, due to the periodic changes in pressure waves, tiny bubbles (cavitation nuclei) in the liquid undergo vibration, growth, and energy accumulation. When the energy inside these bubbles reaches a certain threshold, they collapse and close abruptly. The instantaneous collapse of these bubbles can generate temperatures as high as 5000K and pressures as high as 1800 atm, which can accelerate the contact area between cold water and coffee powder, improving cold extraction efficiency.

[0063] In the specific implementation process of this embodiment 1, such as Figure 5 As shown, the housing assembly 1 includes a housing 11 and a refrigeration module 12 disposed within the housing 11, the cold end of the refrigeration module 12 being connected to the powder hopper 4.

[0064] More specifically, the housing assembly 1 includes a housing 11, with a refrigeration module 12 on one side and a water tank 13 on the other side. A heat dissipation plate 15 is also provided on one side of the refrigeration module 12, with heat dissipation holes that can be square, circular, diamond-shaped, or other shapes. The water tank 13 is connected to the refrigeration module 12 via pipes. Pipes also exist within the refrigeration module 12. Water from the water tank 13 enters the refrigeration module 12 through these pipes, is cooled by the refrigeration module 12, and then connects to the powder hopper 4. A water inlet hole is provided on the hopper cover 42, through which cooled water can enter the hopper body 41.

[0065] The top of the housing 11 is provided with a cover 14, and the cover 14 is provided with a slide at the corresponding position of the pull rod assembly 21.

[0066] Furthermore, after the user turns on the cold brew coffee machine, the cooling module 12 begins cooling. The user selects the desired coffee output and adds the required amount of coffee powder to the powder container 4. The locking mechanism 2 locks the powder container 4 in place. At this time, the pressure component is activated, and the extraction time is set. Initially, the pressure component ensures the pressure in the powder container 4 is below 5 bar for pre-infusion. Later in the set time, the pressure rises to 8 bar, opening the water tank 13 to add water. Simultaneously, the ultrasonic component is activated until the set extraction time is reached. After extraction, the switch at the bottom opening of the container 41 is opened, and the external cup is used to hold the extracted coffee. The resulting coffee is a classic cold brew. This cold brew coffee machine reduces the traditional 14 hours of extraction time to just a few minutes. Due to the shorter extraction time, less aroma molecules evaporate, thus preserving the original flavor and aroma of the coffee beans. From the perspective of the coffee liquid's compound composition, compared to traditional cold brew coffee, under the same conditions, it can achieve a similar aroma and extract more organic compounds in a shorter extraction time.

[0067] In the specific implementation process of this embodiment 1, as shown in Figure 6 and Figure 7 The cold brew coffee machine further comprises a jet assembly 5 connected with the open end of the powder bin 4.

[0068] More specifically, different users have different tastes, and the jet assembly 5 can provide users with diversified coffee tastes. The use of the jet assembly 5 can inject gas into the coffee liquid to produce a dense taste and make the coffee have a certain thickness.

[0069] Further, the open end of the powder bin 4 is connected with the jet assembly 5, and the connection is a threaded connection or other buckle and slot connection and other detachable connection modes.

[0070] In the specific implementation process of this embodiment 1, as shown in Figure 8 and Figure 9 The jet assembly 5 comprises a nozzle 51, a suction chamber 52, a mixing pipe 53 and a diffusion pipe 54. One end of the suction chamber 52 is connected with the open end of the powder bin 4, and the other end is connected with the mixing pipe 53. The mixing pipe 53 is connected with the diffusion pipe 54 and the nozzle 51 in turn.

[0071] More specifically, the jet assembly 5 sprays high-pressure and high-flow water flow at high speed through the nozzle 51 of the diffusion pipe 54, and the air in the suction chamber 52 is continuously taken away to form a local vacuum. Under the action of atmospheric pressure, the well-extracted coffee enters the suction chamber 52 and is mixed with the gas at high speed, disperses the original arrangement state of the coffee liquid molecules, mixes a certain amount of gas in the coffee liquid, and then flows out from the diffusion pipe 52, so that the coffee liquid has a certain dense taste. At this time, it is a cold brew coffee with cream.

[0072] In the specific implementation process of this embodiment 1, as shown in Figure 10 The cold brew coffee machine further comprises a quick release assembly 6, and the jet assembly 5 is connected with the open end of the powder bin 4 through the quick release assembly 6.

[0073] More specifically, the quick release assembly 1 comprises a first quick release part 61 and a second quick release part 62, which are detachably connected. The detachable connection includes a slot, a buckle, a sliding rail or a thread and other detachable connection modes. The first quick release part 61 is detachably connected with the open end of the powder bin 4. When the user needs to prepare a cold brew coffee with cream, the jet assembly 5 can be assembled through the quick release assembly 6.

[0074] Further, the cold brew coffee machine further comprises a water receiving tray, which is detachably connected with the shell 11. The detachable connection includes a slot, a buckle, a sliding rail or magnetic attraction and other detachable connection modes, so that the user can easily take and place the water receiving tray.

[0075] Further, the cold extraction coffee machine is also provided with a damping assembly, which reduces the noise of vibration during extraction.

[0076] Further, the cold extraction coffee machine is also provided with a sterilization assembly, which can adopt any combination of ultraviolet lamp and ozone module, of course, other sterilization methods can also be adopted. The sterilization assembly is used to sterilize the water quality, so as to ensure the safety of coffee use. At the same time, if damaged, it is convenient and simple to replace.

[0077] In the specific implementation process of this embodiment 1, the cold extraction coffee machine is connected with a terminal device, and the terminal device is a mobile phone, a computer or a tablet or other device with a display screen. The user can set the state of the cold extraction coffee machine on the terminal device, such as selecting the liquid output, the liquid temperature, the adaptive extraction scheme of coffee beans, the ultrasonic power, the gas flow rate of the jet assembly, etc., so that the use of the cold extraction coffee machine is more convenient and intelligent.
