[0034] Reference Figure 1 , 3Up to 5, a compact coffee machine, including a base 100, a cup body 200, a quick-connect assembly 300, a cup lid 400, and an extraction module 500; the base 100 is equipped with a power supply assembly 110; a heater 210 is installed at the bottom of the inner liner of the cup body 200, and the heater 210 is electrically connected to a power connection assembly 220. When the cup body 200 is placed on the base 100, the power connection assembly 220 is connected to the power supply assembly 110; the quick-connect assembly 300 is detachably inserted into the cup body 200. Inside the cup, the quick-connect assembly 300 is provided with a water suction pipe 310, the lower section of which is inserted into the inner cavity of the cup body 200; the cup body 200 is detachably installed at one end of the cup lid 400, and a water pump 410 is installed inside the cup lid 400. The inlet of the water pump 410 is connected to the water suction pipe 310, and the water pump 410 draws water out of the cup body 200 through the water suction pipe 310; the extraction module 500 is detachably installed at the other end of the cup lid 400.

[0035] During operation, add an appropriate amount of water to the cup body 200. After adding water, place the cup body 200 on the bottom of one end of the cup lid 400, and then place the cup body 200 on the base 100. Connect the power supply component 110 to the power connection component 220 to supply power to the heater 210. Then, put the coffee capsule, coffee powder, or tea you want to extract into the extraction module 500, and place the extraction module 500 on the bottom of the other end of the cup lid 400. Once ready, heat the water in the cup body 200. After heating, the water pump 410 draws the hot water from the cup body 200 through the water pipe 310, and then pressurizes it before inputting it into the extraction module 500 to achieve high-temperature and high-pressure extraction. If you prefer cold drinks, you can replace the purified water with ice water or add ice cubes to the water tank. Then, without selecting heating, directly select cold extraction on the extraction module 500 on the cup lid. This will give you a cup of high-pressure extracted cold drink with excellent taste and flavor.

[0036] This allows the coffee machine to replace the water tank of existing coffee machines with a cup body of 200, effectively controlling the overall space size of the machine, reducing the overall size of the machine, and making the structure small and compact.

[0037] After use, the base 100, cup body 200, quick-connect assembly 300, cup lid 400, and extraction module 500 can be disassembled for easy storage and carrying.

[0038] In this embodiment, the cup body 200 is a double-walled vacuum stainless steel container with heat preservation effect. After heating, the hot water will not cool down so quickly. Similarly, adding ice water can also delay the heating process, allowing for the simultaneous preparation of several cups without affecting the taste and flavor of the extraction due to temperature.

[0039] Reference Figures 1 to 3The cup lid body 400 includes a bottom shell 420 and a top cover plate 430. The top cover plate 430 is installed over the top opening of the bottom shell 420. One end of the bottom shell 420 is provided with a recessed interface seat 421.

[0040] The quick-connect assembly 300 includes a quick connector 320 and a connector block 330. The quick connector 320 is threaded into the mouth of the cup body 200, and the connector block 330 is detachably installed into the inner cavity of the quick connector 320. The split structure makes the quick connector 320 and the connector block 330 independent of each other. When filling water, there is no need to remove the quick-connect assembly 300 as a whole. You only need to pull out the connector block 330 to carry out the water filling operation, which simplifies the water filling operation and improves convenience.

[0041] Reference Figure 1 , 6 8. The quick connector 320 is provided with a plug 321, and the interface seat 421 has a socket 422. When the cup mouth of the cup body 200 is inserted into the interface seat 421, the plug 321 is inserted into the inner cavity of the cup lid body 400 through the socket 422, and at the same time the plug 321 is locked and fixed by the safety lock assembly 600.

[0042] If the hot water inside the cup body 200 splashes out, it will scald the user. Therefore, the cup body 200 and the cup lid 400 are locked and fixed by the safety lock component 600 to prevent the cup body 200 and the cup lid 400 from separating due to accidents such as falling or collision, and the hot water inside the cup body 200 from splashing out.

[0043] Specifically, the safety lock assembly 600 includes a locking block 610, a locking seat 620, and a button 630. The locking seat 620 is fixed to the top of the interface seat 421 and is located on one side of the socket 422. The locking block 610 is movably mounted on the locking seat 620. An elastic element is installed between the locking block 610 and the locking seat 620. The button 630 is movably mounted on the top plate of the cup lid body 400.

[0044] The button 630 has a first inclined surface, the width of which increases from the lowest end to the highest end of the first inclined surface. The locking block 610 has a second inclined surface, the width of which decreases from the lowest end to the highest end of the second inclined surface. This allows the first and second inclined surfaces to fit together, keeping the locking block 610 in contact with the button 630. At the same time, when the button 630 is pressed down, the highest end of the first inclined surface moves towards the lowest end of the second inclined surface, thereby causing the button 630 to push the locking block 610.

[0045] When locked, when the insert 321 is inserted into the socket 422, the insert 321 pushes the locking block 610, causing the locking block 610 to move and squeeze the elastic element, compressing the elastic element. The elastic force generated by the elastic element causes the locking block 610 to press against the insert 321, making the insert 321 locked and unable to move. At this time, the locking block 610 is in the locked state and working position one. At the same time, the locking block 610 in working position one pushes up the button 630, causing the button 630 to protrude from the top cover plate 430.

[0046] When unlocking, press down on button 630. Button 630 pushes the locking block 610, causing the locking block 610 to move and squeeze the elastic element, causing the locking block 610 to disengage from the insert block 321, releasing the state in which the locking block 610 is pressed against the insert block 321. At this time, the locking block 610 is in the unlocked state and working position two.

[0047] Reference Figure 10 The top of the interface seat 421 is provided with a connecting pipe seat 423. The connecting pipe seat 423 is connected to the water inlet of the water pump 410 through a pipe. When the cup mouth of the cup body 200 is inserted into the interface seat 421, the water pumping pipe 310 is inserted into the inner cavity of the connecting pipe seat 423 to realize the connection of the water inlet channel.

[0048] Reference Figure 3 , 7 12. Specifically, the water pipe 310 includes a connector pipe 311 and a water pipe 312. The connector pipe 311 passes vertically through the connector block 330, and both the top and bottom ends of the connector pipe 311 protrude from the connector block 330. The top end of the connector pipe 311 is used to insert into the inner cavity of the connector seat 423. The water pipe 312 is inserted into the bottom end of the connector pipe 311, and the lower section of the water pipe 312 is inserted into the inner cavity of the cup body 200. The water pipe 312 is usually made of silicone material. After long-term use, it will age and deform. It can be replaced by pulling the damaged or long-used water pipe 312 out of the bottom end of the connector pipe 311.

[0049] Reference Figure 3 , 7 From 10 to 12, because the cup body 200 is equipped with a quick connector 320 at the mouth of the cup body 200, the cup body 200 is in a sealed state. The steam generated during heating will accumulate in the cup body 200, which may lead to danger. Therefore, it is necessary to release the steam from the cup body 200.

[0050] Therefore, an air outlet 431 is provided on the top cover plate 430, and an air guide pipe 424 is provided on the top of the interface seat 421. The top opening of the air guide pipe 424 is located below the air outlet 431. An exhaust channel 331 is provided in the connector block 330. An exhaust hole 332 is opened at the bottom of the exhaust channel 331. The exhaust hole 332 is located above the inner cavity of the cup body 200, and the top channel opening of the exhaust channel 331 is located below the bottom opening of the air guide pipe 424.

[0051] The steam inside the cup body 200 will enter the exhaust channel 331 through the exhaust port 332, then enter the air guide pipe 424, and finally be discharged outside the machine through the air outlet 431, thus avoiding accidents.

[0052] Reference Figure 1 The cup lid 400 also includes a second battery 440, which is used to power the water pump 410.

[0053] Reference Figure 1 , 3 5. The extraction module 500 includes an upper extraction chamber 510 and a lower extraction chamber 520. During operation, coffee powder, coffee capsules, or tea leaves to be extracted are placed into the lower extraction chamber 520 and then screwed into the upper extraction chamber 510 to achieve a seal. The screwed-in extraction module 500 is then connected to the cup lid 400 by a snap fastener on the top of the upper extraction chamber 510. The specific structure of the extraction module 500 can adopt an existing structure.

[0054] Reference Figure 5 The bottom of the cup body 200 is equipped with a temperature sensor 230. The temperature sensor 230 feeds back the water temperature information in the cup to the control board. The control board controls the heater 210 to heat the water to the preset temperature. The preset temperature corresponds to different varieties of coffee beans to meet the extraction needs of different varieties of coffee beans.

[0055] Reference Figure 1 , 5 9. The power supply component 110 adopts the following implementation method:

[0056] Method 1: The power supply component 110 includes an AC power supply module 111 and a lower AC coupler 114. The power connection component 220 includes an upper AC coupler 222. The lower AC coupler 114 is coupled to the upper AC coupler 222 and is connected to the AC power supply module 111.

[0057] Method 1 allows this coffee machine to operate by connecting to mains power.

[0058] Method 2: The power supply component 110 includes a first battery 112 and a lower DC coupler 113. The power connection component 220 includes an upper DC coupler 221. The lower DC coupler 113 is coupled to the upper DC coupler 221 and is connected to the first battery 112. The first battery 112 is a rechargeable battery.

[0059] In method two, this coffee machine can be powered by the first battery 112 to operate, making it convenient to use in outdoor environments or other environments where mains power cannot be accessed.

[0060] Method 3: The power supply component 110 includes an AC power supply module 111, a first battery 112, a lower DC coupler 113, and a lower AC coupler 114; the power connection component 220 includes an upper DC coupler 221 and an upper AC coupler 222.

[0061] The lower DC coupler 113 is coupled to the upper DC coupler 221, and the upper DC coupler 221 is connected to the first battery 112.

[0062] The lower AC coupler 114 is coupled to the upper AC coupler 222, and the lower AC coupler 114 is connected to the AC power supply module 111.

[0063] With method three, this coffee machine can not only make coffee and hot water indoors by connecting to mains power, but also make coffee and hot water using batteries when camping outdoors.
