[0022] In related technologies, coffee is a beverage made from roasted and ground coffee beans. To improve the taste, milk foam is usually added to the coffee. Existing coffee machines are generally equipped with a milk dispenser to make milk foam, but the existing milk dispenser is usually separate from the main body of the coffee machine, which is not only inconvenient for daily use, but also increases the space occupied.

[0023] Reference Figures 1 to 7According to one embodiment of the present invention, a coffee machine with a detachable milk tank includes a coffee machine body 100, a milk tank 200, a locking hook 300, and an adjustment assembly. The coffee machine body 100 is provided with a mounting groove 110, and a locking pin 120 is provided on the wall of the mounting groove 110. The milk tank 200 is provided with a mounting block 201, which is inserted into the mounting groove 110. At least a portion of the locking pin 120 is inserted into the mounting block 201. The locking hook 300 is rotatably disposed on the milk tank 200 so that the locking hook 300 has a release function. In either the locked or locked state, one end of the locking hook 300 is provided with a hook portion 310. When the locking hook 300 is in the locked state, the hook portion 310 abuts against the locking pin 120. When the locking hook 300 is in the unlocked state, the hook portion 310 separates from the locking pin 120. The adjusting component abuts against the locking hook 300. The adjusting component is movably provided in the milk tank 200 so that the locking hook 300 can switch between the unlocked and locked states. In this way, the milk tank 200 can be quickly disassembled and assembled, which can reduce the overall space occupied by the coffee machine.

[0024] For example, when disassembling the milk tank 200, the adjustment component is moved so that the locking hook 300 switches from the locked state to the unlocked state, allowing the mounting block 201 to exit the mounting slot 110, and the milk tank 200 can be removed. When installing the milk tank 200, the mounting block 201 is inserted into the mounting slot 110, and the adjustment component is moved in the opposite direction so that the hook 310 abuts against the locking pin 120, and the locking pin 120 switches from the unlocked state to the locked state, thus fixing the coffee machine body 100 and the milk tank 200. The operation is simple, convenient and quick, and can achieve quick disassembly and assembly of the milk tank 200, which can reduce the overall space occupied by the coffee machine.

[0025] Reference Figure 7 In this embodiment, the adjustment component includes an adjustment member 410 and an elastic member 420. The adjustment member 410 abuts against the end of the locking hook 300 away from the hook portion 310, so that the locking hook 300 switches from the locked state to the unlocked state. The elastic member 420 is disposed between the milk box 200 and the locking hook 300. The elastic member 420 is used to switch the locking hook 300 from the unlocked state to the locked state. The coordinated cooperation of the adjustment member 410 and the elastic member 420 can realize the function of "one-click unlocking and automatic locking", making the disassembly and installation of the milk box 200 smoother and less labor-intensive, and improving the user experience.

[0026] For example, the elastic element 420 is a linear spring. One end of the elastic element 420 abuts against the locking hook 300, and the other end abuts against the lid assembly 220. When the adjusting element 410 pushes the locking hook 300 from the locked state to the unlocked state, the elastic element 420 is compressed and gains elastic potential energy. When the user releases the adjusting element 410, the locking hook 300 rotates in the opposite direction under the action of the elastic element 420, so that the locking hook 300 can automatically spring back. The coordinated cooperation between the adjusting element 410 and the elastic element 420 can realize the function of "one-click unlocking and automatic locking", making the disassembly and installation of the milk box 200 smoother and less strenuous, and improving the user experience.

[0027] In another embodiment, the elastic element 420 is a torsion spring, and the locking hook 300 is provided with a pivot at the middle position. The pivot is rotatably inserted through the box cover assembly 220. The torsion spring is sleeved on the outer periphery of the pivot. The two ends of the torsion spring are respectively connected to the box cover assembly 220 and the locking hook 300, which can also realize the automatic rebound of the locking hook 300. This is not limited here.

[0028] In another embodiment, the adjustment assembly includes an adjustment member 410, and a cover assembly 220 is slidably provided on the locking hook 300. The adjustment member 410 has a first inclined surface and a second inclined surface on opposite sides, and the locking hook 300 has a third inclined surface and a fourth inclined surface on opposite sides. The first inclined surface abuts against the third inclined surface, and the second inclined surface abuts against the fourth inclined surface. When the adjustment member 410 moves, the locking hook 300 can switch between a locked state and an unlocked state by the cooperation of the first and third inclined surfaces and the second and fourth inclined surfaces. This will not be described in detail here.

[0029] Reference Figure 5 , Figure 6 and combined Figure 8 In this embodiment, the milk box 200 includes a box body 210 and a box cover assembly 220. The box body 210 is provided with a receiving cavity for containing milk. The box cover assembly 220 includes a bottom cover 221, a sealing member 222, and a top cover 223. The bottom cover 221 covers the receiving cavity and is provided with a milk foam generating channel. The milk foam generating channel has a steam inlet 230, a milk inlet 240, an air inlet 250, and a milk foam outlet 260. The milk inlet 240 communicates with the receiving cavity. The sealing member 222 covers the milk foam generating channel. The top cover 223 is connected to the bottom cover 221, and the sealing member 222 is located between the bottom cover 221 and the top cover 223. The mounting block 201 is provided on the bottom cover 221. An mounting cavity 202 is formed inside the bottom cover 221. The adjusting member 410 and the elastic member 420 are both accommodated in the mounting cavity 202, which can optimize the internal layout of the milk box 200 and make the structure of the milk box 200 more compact.

[0030] For example, when milk foam is generated, high-temperature steam output from the steam output device inside the coffee machine body 100 flows into the milk foam generation channel through the steam inlet 230, external air flows into the milk foam generation channel through the air inlet 250, and milk in the receiving cavity flows into the milk foam generation channel through the milk inlet 240. After the milk, steam and air are mixed in the milk foam generation channel, milk foam is formed. By integrating the adjusting component 410, the mounting block 201, the elastic component 420 and the locking hook 300 on the lid assembly 220, the internal layout of the milk tank 200 can be optimized, making the structure of the milk tank 200 more compact.

[0031] Reference Figure 7 In this embodiment, a guide structure is provided between the adjusting member 410 and the bottom cover 221, which can guide the adjusting member 410 so that the adjusting member 410 moves in a preset direction, thereby improving the movement stability of the adjusting member 410.

[0032] In this embodiment, the guide structure includes a first waist-shaped hole 411 provided in the adjusting member 410 and a guide protrusion 2211 provided in the bottom cover 221. The guide protrusion 2211 passes through the first waist-shaped hole 411 and abuts against the side wall of the first waist-shaped hole 411, which can guide the adjusting member 410 so that the adjusting member 410 moves in a preset direction, thereby improving the movement stability of the adjusting member 410.

[0033] For example, the first waist-shaped hole 411 is a strip structure, and the guide protrusions 2211 abut against the opposite sidewalls of the first waist-shaped hole 411, which can guide the adjusting member 410 so that the adjusting member 410 moves in a preset direction, thereby improving the moving stability of the adjusting member 410.

[0034] It should be noted that the positions of the first waist-shaped hole 411 and the guide protrusion 2211 can be interchanged. That is, the first waist-shaped hole 411 is located on the bottom cover 221, and the guide protrusion 2211 is located on the adjusting member 410, which can also guide the adjusting member 410. No limitation is made here.

[0035] As another implementation, the guide structure can also be a structure in which a guide shaft and a guide groove cooperate, and there is no limitation here.

[0036] In this embodiment, a limiting structure is provided between the locking hook 300 and the bottom cover 221. The limiting structure is used to limit the rotation angle of the locking hook 300, which can ensure that the locking hook 300 can reliably hook the locking pin 120 in the locked state and fully disengage in the unlocked state to avoid interference.

[0037] In this embodiment, the limiting structure includes a second oblong hole 320 provided in the lock hook 300 and a limiting protrusion 2212 provided in the bottom cover 221. The limiting protrusion 2212 passes through the second oblong hole 320 and abuts against the side wall of the second oblong hole 320, which can ensure that the lock hook 300 can reliably hook the lock pin 120 in the locked state and fully disengage in the unlocked state to avoid interference.

[0038] For example, the second oblong hole 320 has an arc-shaped structure. When the locking hook 300 is in the locked state, the limiting protrusion 2212 abuts against one end of the second oblong hole 320. When the locking hook 300 is in the unlocked state, the limiting protrusion 2212 abuts against the other end of the second oblong hole 320. This ensures that the locking hook 300 can reliably hook the locking pin 120 in the locked state and fully disengage in the unlocked state to avoid interference.

[0039] It should be noted that the positions of the second waist-shaped hole 320 and the limiting protrusion 2212 can be interchanged, that is, the second waist-shaped hole 320 is located on the bottom cover 221, and the limiting protrusion 2212 is located on the adjusting member 410. This is not restricted here.

[0040] As another implementation, the limiting protrusion 2212 can also have a structure in which the limiting groove and the limiting pin cooperate, which will not be described in detail here.

[0041] In this embodiment, a sealing structure is provided between the seal 222 and the bottom cover 221. The sealing structure is used to seal the milk foam generation channel, which can prevent high-pressure steam and milk from leaking from the milk foam generation channel. On the one hand, it can ensure the working pressure and suction force required for the milk foam generation process, and on the other hand, it can maintain the cleanliness and hygiene of the inside of the coffee machine.

[0042] Reference Figures 8 to 10 In this embodiment, the sealing structure includes a sealing groove 290 provided on the bottom cover 221 and a sealing protrusion 2221 provided on the sealing member 222. The sealing groove 290 extends circumferentially along the milk foam generation channel, and the sealing protrusion 2221 is accommodated in the sealing groove 290 and abuts against the side wall of the sealing groove 290. This can prevent high-pressure steam and milk from leaking from the milk foam generation channel. On the one hand, it can ensure the working pressure and suction force required for the milk foam generation process. On the other hand, it can maintain the cleanliness and hygiene of the inside of the coffee machine.

[0043] For example, by adopting a sealing structure in which the sealing groove 290 and the sealing protrusion 2221 interlock, the sealing contact area between the bottom cover 221 and the seal 222 can be increased to provide better radial sealing force. This can withstand the high steam pressure inside the milk foam generation channel and prevent high-pressure steam and milk from leaking from the milk foam generation channel. On the one hand, it can ensure the working pressure and suction force required for the milk foam generation process, and on the other hand, it can maintain the cleanliness and hygiene inside the coffee machine.

[0044] It should be noted that the positions of the sealing groove 290 and the sealing protrusion 2221 can be interchanged, that is, the sealing groove 290 is located on the sealing element 222, and the sealing protrusion 2221 is located on the bottom cover 221. No restrictions are imposed here.

[0045] As another implementation, the sealing structure is a sealing ring, which is sleeved on the outer periphery of the milk foam generating channel and sandwiched between the bottom cover 221 and the sealing element 222. It can also seal the milk foam generating channel, which will not be described in detail here.

[0046] In this embodiment, the milk foam generating channel includes a first channel 270 and a second channel 280 connected to the first channel 270. The steam inlet 230, the milk foam outlet 260, and the milk inlet 240 are all located in the first channel 270. The second channel 280 is provided with an air inlet 250. The air outlet of the second channel 280 is located between the steam inlet 230 and the milk inlet 240. High-speed steam enters the first channel 270 from the steam inlet 230. When it flows through the air outlet of the second channel 280, it will draw air from the air inlet 250 using the Venturi effect. The steam and air mix first to form a gas-liquid two-phase flow. Then, this mixed airflow impacts the milk drawn in from the milk inlet 240, which can better cut and disperse the air in the milk, thereby generating finer and denser milk foam.

[0047] For example, by setting up an independent second flow channel 280 and arranging the air outlet of the second flow channel 280 between the steam inlet 230 and the milk inlet 240, the high-temperature steam mixes with the air first and then acts on the milk. The steam kinetic energy can be used to entice the air, which improves the air mixing efficiency and makes the mixing of milk, steam and air more thorough and uniform, thereby helping to generate milk foam with a finer texture and denser consistency.

[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
