[0029] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described in detail with reference to the embodiments.

[0030] Example 1

[0031] Cold brew coffee cup with straw, including:

[0032] Cup body 1,

[0033] The mechanism 2 has one end inserted into the cup body 1, and the other end is closed at the port of the cup body 1. The mechanism 2 is sealed to the cup body 1. A sealing ring is installed on the mechanism 2, and the mechanism 2 is sealed to the cup body 1 through the sealing ring. The sealing ring is not marked in the attached drawing. A liquid chamber 100 is formed between the mechanism 2 and the cup body 1. When there is no extraction, the liquid chamber 100 is filled with pure water. After cold extraction, the liquid chamber 100 contains coffee liquid.

[0034] The mechanism 2 includes a mechanism housing 21 and an end cap 22. In this embodiment, the end cap 22 is fastened to the mechanism housing 21 with screws. In other embodiments, the end cap 22 can also be snapped onto the mechanism housing 21. The end cap 22 covers the mechanism housing 21 and also covers the port of the cup body 1. A sealing groove is installed on the outer circumferential side wall of the mechanism housing 21, and a sealing ring is installed in the sealing groove. The side of the mechanism housing 21 is provided with a pipe 20 for installing a straw. One end of the pipe 20 passes through the end cap 22, and the other end connects to the liquid chamber 100. During cold brewing, the pipe 20 is blocked. After cold brewing, the part blocking the pipe 20 is removed, the straw is inserted into the pipe 20 and extends into the liquid chamber 100, and people can drink the coffee liquid in the liquid chamber 100.

[0035] The tube 20 on the side of the core housing 21 connects to the end cap 22 at one end and to the liquid chamber 100 at the other end. After cold brewing, you can drink it simply by inserting a straw. The tube design is reasonable, making it easy to insert and use the straw. It is ergonomic and improves the convenience of drinking.

[0036] The cold brew coffee cup also includes a straw. After cold brewing, the straw is inserted into the liquid reservoir 100 through the tube 20. After cold brewing, the user can directly drink the coffee liquid in the liquid reservoir 100 using the straw, without needing any other auxiliary tools or complicated operations such as pouring coffee. Especially in scenarios such as when out and about or exercising, people can operate it with one hand and easily enjoy cold brew coffee, greatly improving the convenience of drinking.

[0037] A cold brew chamber 24 is detachably installed at the lower end of the mechanism housing 21. The cold brew chamber 24 is threadedly connected to the mechanism housing 21; in other embodiments, they can also be snap-fit ​​connected. The cold brew chamber 24 is used to store ice cubes. A coffee powder chamber 25 is detachably installed at the lower end of the cold brew chamber 24. The coffee powder chamber 25 is threadedly connected to the cold brew chamber 24; in other embodiments, they can also be snap-fit ​​connected. The coffee powder chamber 25 is used to hold coffee powder. A first filter 26 is installed between the cold brew chamber 24 and the coffee powder chamber 25. The first filter 26 is used to prevent coffee powder from entering the cold brew chamber 24 and also to support the ice cubes inside the cold brew chamber 24. A second filter is installed at the bottom of the coffee powder chamber 25. The second filter prevents the coffee powder in the coffee powder chamber 25 from directly entering the liquid chamber 100 without cold brewing. The cold brew chamber 24 and the mechanism housing 21, as well as the coffee powder chamber 25 and the cold brew chamber 24, are all detachably connected. Whether threaded or snap-fit ​​connected, this facilitates assembly and disassembly by the user before and after use. After making cold brew coffee, it is easy to thoroughly clean each compartment, keep the inside of the cup hygienic, and prevent coffee residue from affecting the taste during subsequent use.

[0038] Both ends of the cold brew chamber 24 are through-type. The lower end of the core housing 21 has a downwardly extending, annular connector 211. The upper end of the cold brew chamber 24 is sealed and installed on the connector 211. The cold brew chamber 24 and the connector 211 are connected in a sealed, detachable manner, making it convenient for users to remove the cold brew chamber 24 for cleaning and replacement after cold brewing. If the cold brew chamber 24 is damaged or needs to be replaced with a different size cold brew chamber 24 to meet different cold brew needs, the operation is relatively simple, extending the service life of the cold brew coffee cup and improving the practicality of the product.

[0039] The core housing 21 is equipped with a first air pump 27 and a second air pump 28. Both the first air pump 27 and the second air pump 28 are driven by motors. Both the first air pump 27 and the second air pump 28 are connected to the cold extraction chamber 24. The first air pump 27 is used to extract gas from the cold extraction chamber 24, and the second air pump 28 is used to deliver gas to the cold extraction chamber 24.

[0040] During the operation of the cold brew coffee cup, the first air pump 27 and the second air pump 28 work together. When the first air pump 27 is activated, the second air pump 28 is in the off state. The first air pump 27 begins to draw gas from the cold brew chamber 24. As gas is continuously drawn out, a negative pressure environment gradually forms inside the cold brew chamber 24. At this time, a pressure difference is generated between the liquid chamber 100 and the cold brew chamber 24. Under the action of atmospheric pressure, the purified water in the liquid chamber 100 passes through the coffee powder chamber 25 and is forced into the cold brew chamber 24. In this process, the purified water and the coffee powder in the coffee powder chamber 25 come into full contact, and the cold brew reaction begins.

[0041] When it is necessary to recirculate the cold-brewed coffee liquid, the first air pump 27 is turned off and the second air pump 28 is started. The second air pump 28 supplies gas into the cold brew chamber 24, causing the air pressure inside the cold brew chamber 24 to gradually increase. Under the action of positive pressure, the cold-brewed liquid in the cold brew chamber 24 is forced back into the liquid chamber 100 through the coffee powder chamber 25. In this process, the coffee powder chamber 25 acts as a filter device, further filtering impurities in the coffee liquid.

[0042] Thus, by alternately starting the first air pump 27 and the second air pump 28, the liquid repeatedly circulates between the liquid chamber 100 and the cold brew chamber 24, constantly contacting and reacting with the coffee powder to achieve a highly efficient cold brew process. As the number of cycles increases, the effective components of the coffee continuously dissolve into the water, and the concentration and flavor of the coffee liquid gradually reach an ideal state, thereby producing a cold brew coffee with a rich taste and unique flavor for the user.

[0043] A control panel is also installed inside the movement housing 21. The control panel has a display module 29, which displays the working mode of the movement 2 and the cold extraction time. The display module 29, the first air pump 27, and the second air pump 28 are all connected to the control panel. The control panel, display module 29, first air pump 27, and second air pump 28 form an intelligent interactive system. Users can conveniently adjust the air pump operating status through the control panel based on the displayed information, achieving precise control of the cold extraction process and enhancing the product's intelligence and user autonomy.

[0044] Example 2

[0045] Example 2 is basically the same as Example 1, except that a plug 23 is installed on the end cap 22. When the straw is not installed, the plug 23 seals the end of the pipe 20. The plug 23 is installed on the end cap 22. When the straw is needed, the plug 23 can be easily removed to insert the straw. The operation is simple and convenient, and the plug 23 is not easy to lose, making it convenient for the next use.

[0046] Example 3

[0047] Example 3 is essentially the same as Example 1, except that a vertical tube 200 is integrally formed and protrudes upwards inside the core housing 21. A plug 23 seals the vertical tube 200, and a channel 201 is provided on the vertical tube 200. The outer wall of the core housing 21 is recessed inward to form a groove 202, and the channel 201 communicates with the groove 202 to form a pipe 20. By forming a groove 202 by recessing the outer wall of the core housing 21 and communicating with the channel 201 on the vertical tube 200 to form a pipe 20, the internal and external spaces of the core housing 21 are fully utilized. This ingenious design achieves the pipe function without increasing the overall volume of the cup, making the cup structure more compact and the spatial layout more reasonable.
