[0039] The utility model discloses first sealing piece 50 sealed along the axial direction of sleeve 101, and second sealing piece 60 sealed along the radial direction of sleeve 101, so that host computer subassembly 40 and sleeve 101 are sealed well, and first sealing structure cooperates pumping unit to make liquid flow from second chamber 30 to first chamber 102 through brewing pocket, or liquid flows from first chamber 102 to second chamber 30 through brewing pocket, and food material extraction efficiency is higher, and the effect is better.

[0040] In the utility model embodiment, host computer subassembly 40 includes main body 401, and main body 401 is provided with downwardly extending extension 402, and the bottom of main body 401 and extension 402 form mounting recess for detachable connection with sleeve 101, and the end of sleeve 101 is inserted into the mounting recess.

[0041] In the utility model embodiment, the end of sleeve 101 inserted into the mounting recess is provided with first mounting step, first sealing piece 50 is set in the outside of sleeve 101, and first sealing piece 50 is installed at first mounting step position, the axial section of first sealing piece 50 is in zigzag type, and the bottom wall of extension 402 and the inner side wall of extension 402 all abut against first sealing piece 50, and second sealing piece 60 is arranged at the bottom of main body 401, and the top wall of sleeve 101 abuts against second sealing piece 60.

[0042] Thus, the first sealing member 50 is arranged to realize the zigzag type sealing, the zigzag type sealing increases the contact area between the main body 401 and the sleeve 101, and the first sealing member 50 and the second sealing member 60 are arranged to realize the secondary sealing in the axial direction and the radial direction between the main body 401 and the sleeve 101, so that the sealing is good, and the first sealing structure can avoid that the liquid directly flows 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.

[0043] In the embodiment of the utility model, the brewing pocket is arranged close to the connection end of the first chamber 102 and the second chamber 30; the brewing pocket comprises a first filter 103 and a second filter 104, and the first filter 103 and the second filter 104 are arranged inside the sleeve 101; the space surrounded by the first filter 103, the second filter 104 and the sleeve 101 is a brewing space 105 of the brewing pocket.

[0044] Specifically, the first filter 103 and the second filter 104 can both be filter screens, and the mesh number of the filter screens used is determined according to the requirement of minimizing the passing of coffee powder, and of course the liquid can pass through the first filter 103 and the second filter 104.

[0045] In the embodiment of the utility model, the sleeve 101 comprises a first pipe 1011, a second pipe 1012 and a second sealing structure, the first pipe 1011 and the second pipe 1012 are detachably connected, the first filter 103 is arranged between the first pipe 1011 and the second pipe 1012, the second filter 104 is arranged on the second pipe 1012, and the second sealing structure is arranged between the first pipe 1011 and the second pipe 1012.

[0046] In the embodiment of the utility model, the second sealing structure comprises a third sealing member 1013, the first pipe 1011 is arranged close to the end of the second pipe 1012 and is provided with a second mounting step, the third sealing member 1013 is arranged outside the first pipe 1011 and is mounted on the second mounting step, and the axial cross section of the third sealing member 1013 is in a zigzag shape, and the top wall of the second pipe 1012 and the inner side wall of the second pipe 1012 are in abutment with the third sealing member 1013.

[0047] Thus, the third sealing member 1013 is arranged to realize the zigzag type sealing, the zigzag type sealing increases the contact area between the first pipe 1011 and the second pipe 1012, so that the sealing is good, and the second sealing structure can avoid that the liquid directly flows between the first chamber 102 and the second chamber 30 through the connection between the first pipe 1011 and the second pipe 1012 without passing through the brewing pocket.

[0048] Due to the first sealing structure and the second sealing structure, the liquid in the first chamber 102 can only enter the second chamber 30 through the brewing pocket, and the liquid in the second chamber 30 can only enter the first chamber 102 through the brewing pocket, thereby realizing directional reciprocating flow of the liquid and ensuring the extraction effect of the food material.

[0049] Specifically, the first pipe 1011 and the second pipe 1012 are detachably connected by threads, clamping or magnetic attraction, so that the first pipe 1011 and the second pipe 1012 can be separated from each other, and the first pipe 1011 and the second pipe 1012 can be cleaned respectively.

[0050] Specifically, the first filter 103 is clamped between the first pipe 1011 and the second pipe 1012, and the first filter 103 can be separated from the first pipe 1011 and the second pipe 1012, and the first filter 103 can be removed for cleaning.

[0051] It should be noted that the brewing assembly 10 is connected with the main machine assembly 40, and when the brewing assembly 10 and the main machine assembly 40 are integrated, the air suction pump 403 and the air charging pump 404 are in communication with one end of the first chamber 102, and the cup body is only used to provide the second chamber 30, that is, the integrated structure of the brewing assembly 10 and the main machine assembly 40 can be placed in cup bodies of different sizes and can be used, and the extraction of food material can be realized.

[0052] For example, the integrated structure of the brewing assembly 10 and the main machine assembly 40 can be placed in cup bodies of different diameters and can be used, and for cup bodies of different diameters, the user only needs to hold the integrated structure of the brewing assembly 10 and the main machine assembly 40 to form the second chamber 30 between the integrated structure and the cup body, or a simple support can be used to support the integrated structure of the brewing assembly 10 and the main machine assembly 40 on the cup body to form the second chamber 30, which is relatively simple to operate.

[0053] For example, the integrated structure of the brewing assembly 10 and the main machine assembly 40 can be placed in cup bodies of different heights and can be used, and for cup bodies of different heights, only the outer diameter of the integrated structure of the brewing assembly 10 and the main machine assembly 40 needs to be adapted to the diameter of the cup body, and when the integrated structure of the brewing assembly 10 and the main machine assembly 40 is placed in the cup body, the integrated structure of the brewing assembly 10 and the main machine assembly 40 can be supported on the cup body to form the second chamber 30.

[0054] Compared with the relatively complex structure in which the air suction pump 403 and / or the air charging pump 404 are integrated on the cup body, the portable cold brewing cup has a reasonable structure design and higher flexibility, and 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 when going out.

[0055] In some other application scenarios, the portable cold-brewing cup can provide a matched cup body 20, the cup body 20 is detachably connected with the main body 401, a third sealing structure is arranged between the cup body 20 and the main body 401, the third sealing structure comprises a fourth sealing piece 70, a third mounting step is arranged at the middle part of the main body 401, the fourth sealing piece 70 is sleeved outside the middle part of the main body 401, and the fourth sealing piece 70 is mounted at the third mounting step position; the top wall of the cup body 20 and / or the inner side wall of the cup body 20 abut against the fourth sealing piece 70.

[0056] Specifically, the cup body 20 is detachably connected with the main body 401 in a threaded, clamped or magnetically attracted manner, so that the cup body 20 and the main body 401 can be separated from each other, the liquid in the cup body 20 can be poured out by separating the cup body 20 and the main body 401 from each other, and the cup body 20 can be detached for cleaning.

[0057] Referring to the accompanying drawings Figures 1-7 The sleeve 101 is detachably connected with the main body 401 in a threaded manner; the first pipe 1011 and the second pipe 1012 are detachably connected in a threaded manner; the cup body 20 is clamped with the main body 401, that is, when the opening of the cup body 20 faces upward, the main body 401 is pressed on the cup body 20 under the action of gravity, and the user can pull out the integrated main machine assembly 40 and brewing assembly 10 upward, so that the user can take out the integrated main machine assembly 40 and brewing assembly 10 to add liquid or pour out the extracted liquid, or the user can not take out the integrated main machine assembly 40 and brewing assembly 10, but directly add liquid or pour out the extracted liquid by using the water nozzle 201.

[0058] In the embodiment of the utility model, the pumping unit includes a suction pump 403 and an air pump 404, the suction pump 403 and the air pump 404 are communicated with one end of the first chamber 102, and the other end of the first chamber 102 is communicated with the second chamber 30.

[0059] In the embodiment of the utility model, the main machine assembly 40 further includes a connecting pipeline (not shown in the drawings) and an air nozzle 405, the suction pump 403 and the air pump 404 are arranged inside the main body 401; the connecting pipeline is in the shape of "T" as a whole, the first end of the connecting pipeline is communicated with the suction pump 403, the second end of the connecting pipeline is communicated with the air pump 404, the third end of the connecting pipeline is communicated with the air nozzle 405, and the air nozzle 405 extends into the first chamber 102.

[0060] Specifically, the above-mentioned connecting pipeline is a flexible pipeline or a rigid pipeline, and the flexible pipeline can be a silica gel hose or a plastic hose.

[0061] In other embodiments, the air suction pump 403 and the air charging pump 404 are correspondingly provided with a connecting pipe and an air nozzle 405, that is, two connecting pipes and two air nozzles 405 are provided, and the two air nozzles 405 extend to the inside of the first chamber 102; compared with the two air nozzles 405, the one air nozzle 405 simplifies the overall structure and is more portable.

[0062] It should be noted that in use, food materials such as coffee powder are placed in the brewing bag, and an appropriate amount of normal-temperature or low-temperature liquid such as warm water or ice water is filled in the cup body 20; the brewing assembly 10 is inserted into the inside of the cup body 20 to form the second chamber 30; first, the air suction pump 403 is controlled to perform air suction on the first chamber 102, and the liquid in the second chamber 30 flows to the first chamber 102 through the brewing bag, and the liquid soaks the food materials; then, the air charging pump 404 is controlled to charge air to the first chamber 102, and the liquid in the first chamber 102 flows to the second chamber 30 through the brewing bag; in this way, the liquid can reciprocally flow between the first chamber 102, the brewing bag and the second chamber 30 to achieve extraction of the food materials; in order to increase the taste of the extracted liquid, the extracted liquid can also be placed in other refrigeration equipment for refrigeration treatment.

[0063] Further, the air charging pump 404 can be controlled to start working after a period of time after the air suction pump 403 stops working, so that the food materials in the brewing bag can be fully soaked by the liquid, and the extraction effect of the food materials is better.

[0064] In the embodiment of the utility model, the host assembly 40 further includes a first liquid level detection member 406 and a second liquid level detection member 407, the first liquid level detection member 406 is arranged at the bottom of the host assembly 40 and extends to the first chamber 102, and the second liquid level detection member 407 is arranged at the side of the host assembly 40 and extends to the second chamber 30.

[0065] Specifically, the first liquid level detection member 406 and the second liquid level detection member 407 can both adopt an existing liquid level sensor.

[0066] The first liquid level detection member 406 detects the liquid level height in the first chamber 102, and the second liquid level detection member 407 detects the liquid level height in the second chamber 30.

[0067] When the air suction pump 403 performs air suction on the first chamber 102 through the connecting pipe and the air nozzle 405, a negative pressure is formed in the inside of the first chamber 102 relative to the second chamber 30, and in the process that the liquid in the second chamber 30 flows to the first chamber 102, the liquid level in the first chamber 102 rises and the liquid level in the second chamber 30 drops; when the liquid level in the first chamber 102 rises to the detection position of the first liquid level detection member 406, the air suction pump 403 stops working.

[0068] When the inflator pump 404 inflates the first chamber 102 through the connecting pipe and the air nozzle 405, the interior of the first chamber 102 forms a positive pressure relative to the second chamber 30, and the liquid level in the first chamber 102 drops while the liquid in the first chamber 102 flows to the second chamber 30, and the liquid level in the second chamber 30 rises, and when the liquid level in the second chamber 30 rises to the detection position of the second liquid level detection member 407, the inflator pump 404 stops working.

[0069] Specifically, the setting height of the detection position of the first liquid level detection member 406 and the setting height of the detection position of the second liquid level detection member 407 are determined according to the actual application scene and are not limited.

[0070] Therefore, the first liquid level detection member 406 can be used to detect and determine the highest liquid level in the first chamber 102, so as to avoid that the liquid in the first chamber 102 enters the interior of the host assembly 40 through the air nozzle 405 when the portable cold brewing cup is used for cold brewing; and the second liquid level detection member 407 can be used to detect and determine the highest liquid level in the second chamber 30, so as to avoid that the liquid in the second chamber 30 spills out from the water nozzle 201 position of the cup body 20 when the portable cold brewing cup is used for cold brewing.

[0071] In the embodiment of the utility model, the host assembly 40 further includes an electronic control unit 408 and a charging battery 409, and the inflator pump 404, the air suction pump 403, the first liquid level detection member 406, the second liquid level detection member 407, the electronic control unit 408 and the charging battery 409 are electrically connected.

[0072] In this way, the detection results of the first liquid level detection member 406 and the second liquid level detection member 407 can be transmitted to the electronic control unit 408, and the electronic control unit 408 controls the inflator pump 404 or the air suction pump 403 to work according to the detection results; how the inflator pump 404, the air suction pump 403, the first liquid level detection member 406, the second liquid level detection member 407, the electronic control unit 408 and the charging battery 409 are electrically connected can be realized by using the existing technology, and details are not described herein.

[0073] In the embodiment of the utility model, the host assembly 40 further includes a safety valve 80, and the safety valve 80 is arranged near the air nozzle 405.

[0074] Specifically, the safety valve 80 includes a float ball and a valve body, the float ball is arranged in the inner cavity of the valve body 80, the upper portion of the valve body 80 is provided with a first channel communicating with the inner cavity and the air nozzle 405, the side of the valve body is provided with a second channel communicating with the inner cavity and the first chamber 102, the bottom of the valve body is provided with a third channel communicating with the inner cavity and the first chamber 102, and the second channel is arranged above the third channel.

[0075] When the suction pump 403 sucks, the suction force of the suction pump 403 is less than the gravity of the floating ball, and the floating ball is close to the third channel under the action of its gravity; when the suction pump 403 sucks 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 405, so that the first chamber 102 forms a negative pressure relative to the second chamber 30, and the liquid in the second chamber 30 flows to the first chamber 102 through the brewing cover.

[0076] When the inflation pump 404 inflates the first chamber 102, the floating ball is close to the third channel under the action of its gravity, and the inflation pump 404 inflates the first chamber 102 through the air nozzle 405, the first channel of the safety valve 80 and the second channel 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 cover.

[0077] The buoyancy of the floating ball is greater than its gravity; when the first liquid level detection member 406 fails, the first chamber 102 may have a high liquid level, and since the safety valve 80 is provided, when the liquid in the first chamber 102 enters the safety valve 80 through the third channel of the safety valve 80, the buoyancy of the floating ball is greater than its gravity, and the floating ball can float to block the first channel, preventing the liquid from entering the main machine assembly 40 through the air nozzle 405.
