[0033] The present invention will be further described in detail below with reference to specific embodiments.

[0034] Example 1

[0035] The beverage cup structure in this embodiment is as follows: Figure 1 , Figure 2 As shown, the beverage cup includes a lid 5, a cup body 1 forming a cup cavity, and a pressure device 2 that descends along the side wall of the cup cavity for pressure application. The pressure device 2 includes an upper part 21 and a lower part 22 that are detachably connected by threads. The lower part 22 of the pressure device 2 is a placement part for placing solid raw materials, with an open top and a drip filter 221 at the bottom. The upper part 21 of the pressure device 2 is an operating part, which has a cylindrical structure. The cylindrical cavity serves as a water storage chamber 212, and the bottom of the cylinder is equipped with a pressure filter 222. The top of the cylinder has an opening 213, and the edge of the opening 213 forms an outwardly flange 211 for operation. This beverage cup is equipped with a detachable elastic sealing sleeve 4 and a sealing ring 3 for the pressure device 2. Figure 2 Starting from the initial state, coffee powder is placed into the placement section through the opening. Then, the lower part 22 containing the coffee powder is attached to the bottom of the upper part 21. The sealing ring 3 is clamped between the upper end face of the lower part 22 and the French press filter element 222. The placement section and the upper part 21 together form a receiving cavity 223 to retain the coffee powder (see...). Figure 3 , Figure 4 The receiving cavity 223 is located between the drip filter element 221 and the pressure filter element 222, and the sealing ring 3 seals the connection between the upper part 21 and the lower part 22 (see...). Figure 4 To prevent coffee powder from leaking out of the receiving cavity 223 from the connection point, the water storage cavity 212 is connected to the receiving cavity 223 via the French press filter element 222. After assembly, an elastic sealing sleeve 4 is fitted onto the outer wall of the French press device 2 to obtain the French press device 2 containing coffee powder.

[0036] When the beverage cup is used as a pressure brewing device, the accommodating cavity 223 serves as a pressure space. When in use, water is first added into the cup cavity, and then the pressure brewing device 2 with coffee powder is placed into the cup cavity. The upper part 21 drives the lower part 22 to descend along the side wall of the cup cavity until the water surface is above the accommodating cavity, and then the operation is paused. At this time, the elastic sealing sleeve 5 is clamped between the pressure brewing device 2 and the inner side wall of the cup cavity, and the pressure brewing device 2 is thereby fixed on the cup body 1. Water soaks the coffee powder in the accommodating cavity 223 to realize extraction. After several minutes of extraction, coffee liquid is prepared, and then the operation of the upper part 21 driving the lower part 22 to descend is continued. The coffee liquid is lifted from the accommodating cavity 223 to the water storage cavity 212 above the pressure filter 222, and the coffee residue left after the coffee powder is extracted is retained in the accommodating cavity 223 because it cannot pass through the pressure filter 222 and the drip filter 221. The pressure brewing device 2 is lowered until the lower part 22 reaches the bottom wall of the cup cavity, and the pressure brewing is completed. In this state, the outer turning edge 211 of the upper part 21 is supported on the cup mouth edge higher than the cup mouth (for example, the cup body 1 is higher than the cup mouth 2, and the outer turning edge 211 of the upper part 21 is supported on the cup mouth edge higher than the cup mouth 2). Figure 3 After the pressure brewing is completed, the pressure brewing device 2 does not need to be taken out of the cup cavity. The coffee liquid in the water storage cavity 212 can be directly poured out through the barrel mouth 213 of the upper part 21 for drinking, or the pressure brewing device 2 can be taken out by holding the outer turning edge 211. At this time, the coffee liquid in the water storage cavity 212 flows back to the cup cavity through the accommodating cavity 223, and the drinker drinks the coffee liquid in the cup cavity.

[0037] When the beverage cup is used as a drip filter brewing device, the pressure brewing device 2 serves as a drip filter device, and the accommodating cavity 223 serves as a drip filter space. When in use, the pressure brewing device 2 with coffee powder is placed into the cup cavity. The upper part 21 drives the lower part 22 to descend along the side wall of the cup cavity to an appropriate height, and then the operation is paused. At this time, the elastic sealing sleeve 5 is clamped between the drip filter device and the inner side wall of the cup cavity, and the drip filter device is thereby fixed on the cup body (for example, the cup body 1 is higher than the cup mouth 2, and the outer turning edge 211 of the upper part 21 is supported on the cup mouth edge higher than the cup mouth 2). Figure 5 Then, the operator adds water into the water storage cavity 212 through the barrel mouth 213 of the upper part 21. The water storage cavity 212 supplies water to the accommodating cavity 223 through the pressure filter 222. The water soaks the coffee powder in the accommodating cavity 223 to prepare coffee liquid, and the coffee liquid drips through the drip filter 221 of the lower part 22 to the cup cavity.

[0038] See Figure 2 and Figure 3, the lower part 22 of the press device 2 comprises a support frame 224 and a drip filter 221 mounted on the support frame 224, the drip filter 221 is arched downward to form an inverted cone shape, and the support frame 224 is made of hard material. When brewing drip coffee, the downward arched shape of the drip filter 221 is close to the existing drip brewing device, and can brew pure-taste drip coffee. When brewing press coffee, the lower part 22 of the press device 2 is lowered, and the downward arched shape of the drip filter 221 allows the water in the cup cavity to impact the coffee powder in the containing cavity 223 from multiple directions through the drip filter 221, thereby playing a role of stirring the coffee powder. Without the need for an additional stirring rod, the coffee powder can be fully extracted. Since the drip filter 221 is mounted on the support frame 224, it can still maintain the downward arched shape under the impact of water. When the lower part 22 of the press device 2 is lowered to the bottom of the cup cavity, the support frame 224 is supported on the bottom wall of the cup cavity to prevent the drip filter 221 from being deformed under pressure.

[0039] Embodiment Two

[0040] The structure of the beverage cup of the present embodiment is shown in Figure 6 , which comprises a cup cover 5, a cup body 1 forming a cup cavity, and a press device 2 that can be lowered along the side wall of the cup cavity for press brewing. The press device 2 comprises an upper part 21 and a lower part 22 that are detachably connected by threads. The lower part 22 of the press device 2 comprises a support frame 224 made of hard material and a drip filter 221 mounted on the support frame 224 (see Figure 6 and Figure 7 ). The upper part 21 of the press device 2 is an operating part, which is a cylindrical structure. The cylindrical cavity serves as a water storage cavity 212. A cylinder port 213 is opened at the top of the cylinder. The edge of the cylinder port 213 forms an outer flange 211 for operation. The bottom of the cylinder is a placement part for placing solid raw materials. The press device 2 is provided with a press filter 222 as the top wall of the placement part, and the lower end of the placement part is open. The beverage cup is provided with a detachable elastic sealing sleeve 4 for the press device 2. Starting from the state shown in Figure 6 , turn the upper part 21 over so that the bottom is upward, put coffee powder into the placement part through the opening of the placement part, and then splice the lower part 22 to the upper part 21 to cover the opening. Then, the placement part and the lower part 22 together enclose a containing cavity 223 (see Figure 7 and Figure 8 ) to hold the coffee powder. The containing cavity 223 is located between the drip filter 221 and the press filter 222, and the water storage cavity 212 is connected to the containing cavity 223 through the press filter 222. After splicing, the elastic sealing sleeve 4 is sleeved on the outer wall of the press device 2 to obtain the press device 2 containing coffee powder.

[0041] The beverage cup is used as a pressure brewing device. The accommodating cavity 223 is used as a pressure space. When used, water is first added into the cup cavity, and then the pressure brewing device 2 with coffee powder is placed into the cup cavity with the accommodating cavity facing downwards. The upper part 21 drives the lower part 22 to descend along the side wall of the cup cavity until the water surface is higher than the accommodating cavity 223. Then the operation is paused. At this time, the elastic sealing sleeve 5 is clamped between the pressure brewing device 2 and the inner side wall of the cup cavity. The pressure brewing device 2 is thereby fixed on the cup body 1. Water soaks the coffee powder in the accommodating cavity 223 to realize extraction. After several minutes of extraction, coffee liquid is prepared. Then the operation is continued to drive the lower part 22 to descend, so that the coffee liquid rises from the accommodating cavity 223 to the water storage cavity 212 above the pressure filter 222, while the coffee residue left after the coffee powder is extracted is retained in the accommodating cavity 223 because it cannot pass through the pressure filter 222. The pressure brewing device 2 is lowered until the lower part 22 reaches the bottom wall of the cup cavity, and the pressure brewing is completed. In this state, the outer flange 211 of the upper part 21 is supported on the rim of the cup mouth which is higher than the cup mouth (for example, the rim of the cup mouth is higher than the cup mouth by 5mm). Figure 7 After the pressure brewing is completed, the pressure brewing device 2 does not need to be taken out of the cup cavity. The coffee liquid in the water storage cavity 212 can be directly poured out through the barrel mouth 213 of the upper part 21 for drinking. The pressure brewing device 2 can also be taken out by holding the outer flange 211. At this time, the coffee liquid in the water storage cavity 212 flows downwards through the accommodating cavity 223 into the cup cavity, and the drinker drinks the coffee liquid in the cup cavity.

[0042] The beverage cup is used as a pressure brewing device. The accommodating cavity 223 is used as a pressure space. When used, water is first added into the cup cavity, and then the pressure brewing device 2 with coffee powder is placed into the cup cavity with the accommodating cavity facing downwards. The upper part 21 drives the lower part 22 to descend along the side wall of the cup cavity until the water surface is higher than the accommodating cavity 223. Then the operation is paused. At this time, the elastic sealing sleeve 5 is clamped between the pressure brewing device 2 and the inner side wall of the cup cavity. The pressure brewing device 2 is thereby fixed on the cup body 1. Water soaks the coffee powder in the accommodating cavity 223 to realize extraction. After several minutes of extraction, coffee liquid is prepared. Then the operation is continued to drive the lower part 22 to descend, so that the coffee liquid rises from the accommodating cavity 223 to the water storage cavity 212 above the pressure filter 222, while the coffee residue left after the coffee powder is extracted is retained in the accommodating cavity 223 because it cannot pass through the pressure filter 222. The pressure brewing device 2 is lowered until the lower part 22 reaches the bottom wall of the cup cavity, and the pressure brewing is completed. In this state, the outer flange 211 of the upper part 21 is supported on the rim of the cup mouth which is higher than the cup mouth (for example, the rim of the cup mouth is higher than the cup mouth by 5mm). Figure 8 After the pressure brewing is completed, the pressure brewing device 2 does not need to be taken out of the cup cavity. The coffee liquid in the water storage cavity 212 can be directly poured out through the barrel mouth 213 of the upper part 21 for drinking. The pressure brewing device 2 can also be taken out by holding the outer flange 211. At this time, the coffee liquid in the water storage cavity 212 flows downwards through the accommodating cavity 223 into the cup cavity, and the drinker drinks the coffee liquid in the cup cavity.

[0043] See Figure 6-8 The pressure filter 222 is arched upwards to form a taper as the top wall of the placement portion. In this way, a larger placement space is formed, and the surface area is also larger compared with the filter screen of the existing pressure brewing kettle. When brewing pressure coffee, more coffee liquid can pass through the pressure filter 222 to rise above the pressure filter 222 in unit time, and the speed of filtering coffee residue is faster.

[0044] Example Three

[0045] The beverage cup structure of the example is shown in Figure 9As shown, the device includes a cup lid 5, a cup body 1 forming a cup cavity, and a pressure device 2 that can descend along the side wall of the cup cavity for pressure application. The pressure device 2 includes an upper part 24 and a lower part 25 that are detachably connected by threads. The lower part 25 of the pressure device 2 is a placement part for placing solid raw materials. The top of the placement part is open and the bottom wall is a drip filter element 253. The side wall of the lower part 25 is provided with a hanging ear 251 and a receiving groove 252 for accommodating the hanging ear. The upper end of the hanging ear 251 is hinged to receive the groove wall of the receiving groove 252, and the lower end is a movable end that can be rotated and opened around the upper end. The lower end of the hanging ear 251 is normally recessed into the receiving groove 252. The upper part 24 of the pressure device 2 is an operating part. The operating part has a cylindrical structure, and the cylindrical cavity serves as a water storage cavity 243. The top of the cylinder has a cylinder opening 242, and the edge of the cylinder opening 242 forms an outward flange 241 for operation.

[0046] In this embodiment, the French press device 2 is equipped with a removable elastic sealing sleeve 4. When this beverage cup is used as a French press brewing device, from... Figure 9 Starting from the indicated state, connect the lower part 25 to the bottom of the upper part 24, and use the elastic sealing sleeve 26 to cover the outside of the lower part 25's receiving groove 252. Then, put coffee powder into the cup cavity and add an appropriate amount of water. Stir and mix well with a stirring rod. Then, put the French press device 2 into the cup cavity. At this time, the drip filter 253 acts as the French press filter. A French press space is formed between the filter 253 and the bottom wall of the cup cavity. In the French press space, water extracts coffee powder. After a few minutes of extraction, coffee liquid is made. Then, operate the... Part 24 lowers the lower part 25, causing the coffee liquid to rise from the French press space through the French press filter 253 to the water storage chamber 243 above the French press filter 253. Coffee grounds remaining after extraction cannot pass through the French press filter 253 and remain in the French press space. The elastic sealing sleeve 26 clamps between the French press device 2 and the inner wall of the cup cavity, preventing coffee grounds from flowing from the gap between the French press device 2 and the cup cavity to the upper part of the French press space, and also acting as a stop to prevent the hanging handle 251 from opening outwards. French pressing is complete when the lower part 25 descends to the bottom wall of the cup cavity. In this state, the outward-flared edge 241 of the upper part 24 supports the rim of the cup, higher than the rim (e.g., ...). Figure 10 After the French press is completed, there is no need to remove the French press device 2 from the cup cavity. The coffee liquid in the water storage chamber 243 can be poured directly out through the cylinder opening 242 of the upper part 24 for drinking. Alternatively, the French press device 2 can be removed by hand by the outward-folding edge 241. At this time, the coffee liquid in the water storage chamber 243 will flow down through the French press space into the cup cavity, and the drinker can then drink the coffee liquid in the cup cavity.

[0047] When this beverage cup is used as a drip brewing device, the French press 2 serves as the drip filter. The operator removes the lower part 25, i.e., the placement part, of this device. The cavity formed in the placement part 25 for placing solid ingredients serves as the drip space. The operator then adds coffee powder into the drip space and opens the hanging ear 251 that is recessed into the storage slot 252, so that the lower part 25 is fixed to the edge of the cup by the hanging ear 251 (e.g., ...). Figure 11) and then water is added to the drip space through the opening of the lower portion 25, the water extracts the coffee powder in the drip space to form an extract, the extract drips through the drip filter 253 of the lower portion 25 into the cup cavity, and the coffee residue left after the extraction of the coffee powder remains in the drip space because it cannot pass through the drip filter 253.

[0048] See Figure 9-11 The lower portion 25 includes a support frame 254 and a drip filter 253 mounted on the support frame 254, the drip filter 253 is arched downward to form an inverted cone shape, and the support frame is made of a hard material. When brewing drip coffee, the arched shape of the drip filter 253 is closer to the existing drip brewing device, and can brew pure-tasting drip coffee. When brewing espresso, the drip filter 253 also serves as an espresso filter. Compared with the filter screen of the existing espresso pot, the filter has a larger surface area, and more coffee liquid can pass through the espresso filter to rise above the espresso filter in a unit of time, and the speed of filtering the coffee residue is faster. When the espresso device 2 is operated until the lower portion 22 reaches the bottom of the cup cavity, the support frame 254 supports the drip filter 253 to prevent it from being deformed by pressure. The drip filter 253 is mounted on the support frame 254 and can maintain its arched shape under water impact. When the lower portion 25 of the espresso device 2 descends to the bottom of the cup cavity, the support frame 254 is supported on the bottom wall of the cup cavity to prevent the drip filter 253 from being deformed by pressure.

[0049] Example Four

[0050] The structure of this embodiment is basically the same as that of Example Three, except that the lower portion of this embodiment does not have a hanging ear and a receiving slot for accommodating the hanging ear, and the elastic sealing sleeve of this embodiment also serves as a fixing member that is clamped between the outer wall of the drip device and the side wall of the cup cavity to fix the drip device to the cup body.

[0051] In other embodiments, the upper portion and the lower portion of the espresso device can be replaced by a non-detachable connection, and the espresso device can also not include an upper portion and a lower portion, but be an integrally formed cylindrical structure, the cylindrical cavity serving as a water storage cavity and a drip space, the top of the cylinder being open and the bottom being provided with a drip filter and an espresso filter.

[0052] As described above, only the embodiments of the present invention are limited to the scope of patent protection. Those skilled in the art can make non-essential changes or substitutions based on the present invention, which still falls within the scope of patent protection.
