[0056] Therefore, the first sealing structure 50 can avoid the liquid flowing between the first chamber 102 and the second chamber 30 through the connection between the main body 401 and the sleeve 101 without passing through the brewing pocket.

[0057] Specifically, the sleeve 101 and the main body 401 are detachably connected through threads, clamping or magnetic attraction, so that the sleeve 101 and the main body 401 can be separated from each other, and the sleeve 101 can be detached from the main body 401 for cleaning.

[0064] It should be noted that, since the brewing assembly 10 and the main machine assembly 40 are integrally arranged in cups of different sizes, the extraction of food materials can be realized, in some application scenarios, the user can only carry the brewing assembly 10 and the main machine assembly 40 of the portable cold brewing cup for travel; in some other application scenarios, the portable cold brewing cup can provide a matched cup 20, at this time, the cup 20 and the main body 401 are detachably connected, and the third sealing structure 60 is arranged between the cup 20 and the main body 401.

[0065] Specifically, the third sealing structure 60 is a rubber ring or a silica gel ring.

[0067] Referring to the accompanying drawings Figures 1-5 The sleeve 101 and the main body 401 are detachably connected through threads, the first pipe 1011 and the second pipe 1012 are detachably connected through threads, and the cup 20 and the main body 401 are clamped, that is, when the opening of the cup 20 faces upward, the main body 401 is pressed on the cup 20 under the action of gravity, and the user can pull out the main machine assembly 40 and the brewing assembly 10 which are integrally connected upward.

[0068] In the embodiment of the utility model, for the portable cold brewing cup, the matched cup 20 is provided, the opening position of the cup 20 is provided with a water nozzle 201, the water nozzle 201 is outwardly inclined, the main body 401 is large at the bottom and small at the top as a whole, the upper part of the main body 401 supports on the opening of the cup 20, the lower part of the main body 401 is inserted in the inside of the cup 20, the middle part of the main body 401 has an arc guide part 409, the arc guide part 409 and the water nozzle 201 form an outwardly inclined guide channel 70, and the guide channel 70 communicates with the second cavity 30.

[0069] Further, since the air nozzle 404 is arranged in the first chamber 102 and the guide channel 70 and the water nozzle 201 are arranged, the user can pour out the extracted liquid by pouring the portable cold brewing cup in the direction of the water nozzle 201 without taking out the main machine assembly 40 and the brewing assembly 10, while keeping the first chamber 102 in a negative pressure state relative to the second chamber 30, that is, the liquid in the first chamber 102 flows to the second chamber 30 as much as possible; in this process, the inflation pump 403 can be kept in a working state to drive the liquid in the first chamber 102 to flow to the second chamber 30, and the liquid in the first chamber 102 is in a small state, so the liquid in the first chamber 102 will not enter the air nozzle 404 due to the pouring of the portable cold brewing cup; and the user does not need to take down and find a place to place the main machine assembly 40 and the brewing assembly 10 when pouring out the liquid, thereby avoiding the pollution of the food material residues in the main machine assembly 40 and the brewing assembly 10 to the outside, such as the pollution of coffee residues to the outside, and facilitating the maintenance of a clean environment.

[0070] Specifically, the third sealing structure 60 seals between the main body 401 and the cup body 20, so that when the portable cold brewing cup is poured, the liquid can only be poured out from the position of the water nozzle 201, avoiding the liquid from being poured out from other positions of the opening of the cup body 20 to pollute the clothes of the user, etc., so that directional liquid outflow can be realized.

[0071] In the embodiment of the utility model, the main machine assembly 40 further includes a safety valve 80, which is arranged close to the position of the air nozzle 404.

[0073] When the suction pump 402 sucks air, the suction force of the suction pump 402 is smaller than the gravity of the float ball, and the float ball is close to the third channel under the action of its gravity; when the suction pump 402 pumps air to the first chamber 102, the gas in the first chamber 102 is discharged outward through the second channel of the safety valve 80, the first channel of the safety valve 80 and the air nozzle 404, so that a negative pressure is formed in the first chamber 102 relative to the second chamber 30, and the liquid in the second chamber 30 flows to the first chamber 102 through the brewing pocket.

[0074] When the inflator 403 inflates the first chamber 102, the ball floats close to the third passage under the action of its gravity, the inflator 403 inflates the first chamber 102 through the air nozzle 404, the first passage of the safety valve 80 and the second passage of the safety valve 80, so that the first chamber 102 forms a positive pressure relative to the second chamber 30, and the liquid in the first chamber 102 flows to the second chamber 30 through the brewing pocket.

[0075] The buoyancy of the ball is greater than its gravity, when the first liquid level detection member 405 fails, the first chamber 102 may have a too high liquid level, since the safety valve 80 is arranged, when the liquid in the first chamber 102 enters the safety valve 80 through the third passage of the safety valve 80, the buoyancy of the ball is greater than its gravity, the ball can float up to block the first passage, avoiding the liquid entering the main machine assembly 40 through the air nozzle 404.
