[0002] When tasting coffee, people like to add foamed milk, which will make the coffee taste more delicate and silky. At the same time, the milk with milk foam can also pull out beautiful milk flowers, which is highly ornamental. The thickness of the milk foam required for cappuccino and latte, which people often drink, adopts different ratios, and the taste of milk foam of different thicknesses is also different. Milk foam is formed by mixing air or water vapor into milk. Common frothing methods on the market include steam injection and stirring. Stirring and frothing refers to the rapid mixing of air into milk to form milk foam through the impact force brought by the high-speed rotating stirring rod. The existing stirring device is relatively simple in design, and a single stirring shaft is often used for rotation operation. The stirring efficiency is low, the fluidity of milk in the stirring chamber is insufficient, and the liquid milk cannot be fully stirred. The mixing process takes a long time to achieve the desired effect, which not only affects the efficiency of the milk foam machine, but also may cause the temperature of the milk to rise during the stirring and rotating process, which ultimately affects the quality of the milk foam.

[0003] At the same time, the stirring device is often designed as an integrated unit with the cup body, which is not easy to disassemble and increases the difficulty of cleaning. The driving mechanism of the stirring device is arranged on the top of the cup body, which has a complex structure and high cost, occupies a large amount of internal space, and has low space utilization. Therefore, in order to solve the above drawbacks, a milk frothing machine is urgently needed. Summary of the invention

[0030] The present invention is further described in detail below with reference to the accompanying drawings. A milk frothing machine comprises a cup body 1 and a base below the cup body 1, wherein the cup body 1 is hollow and open to form a stirring chamber, a cup cover 2 is installed to cover the end of the stirring chamber, a stirring component 3 is detachably inserted into the bottom of the cup cover 2 through a mounting seat 21, and a driving mechanism 4 drives the stirring component 3 to rotate in the stirring chamber; The stirring assembly 3 includes a stirring shaft 31 connected to the cup cover 2, a rotating seat 32 is provided at the bottom of the stirring shaft 31, a stirring head 33 is rotatably mounted outside the rotating seat 32, and the stirring head 33 is suspended and installed at the bottom of the cup cover 2, and an upper magnetic material 38 is installed at the bottom of the stirring head 33 through a fixed seat 37; The driving mechanism 4 includes a driving motor 41 installed at the outer bottom of the cup body 1, and a lower magnetic material 42 connected to the main shaft 411 of the driving motor 41. The lower magnetic material 42 and the upper magnetic material 38 attract each other. When the driving motor 41 rotates, the upper magnetic material 38 is driven to rotate through the lower magnetic material 42, thereby driving the stirring head 33 to rotate. The stirring shaft 31 is also provided with a mesh ring 34, and the mesh ring 34 is provided with flow guide holes 341 through its upper and lower end surfaces, and the flow guide holes 341 are covered with a dividing net 6, and the mesh ring 34 is coaxially connected with the stirring head 33 and rotates; A plurality of flow-pushing tables 343 are also provided at the bottom of the separation net ring 34. When the stirring head 33 and the separation net ring 34 rotate, the flow-pushing tables 343 are driven to rotate, thereby disturbing the movement of the milk.

[0031] The upper end surface of the isolation net ring 34 is provided with a sunken installation ring 342 , the guide hole 341 passes through the bottom of the installation ring 342 , and the partition net 6 is installed in the installation ring 342 .

[0032] A fixing ring 7 is also installed in the installation ring 342 , and the dividing net 6 is clamped and installed between the fixing ring 7 and the installation ring 342 .

[0033] The flow pushing platform 343 is arranged at the bottom of the isolation mesh ring 34 in the shape of an arc platform and extends downward and outward.

[0034] The guide holes 341 and the flow pushing platform 343 are both provided with three, which are distributed on the isolation mesh ring 34 in a circular array, and the guide holes 341 are provided through the interior of the flow pushing platform 343 .

[0035] A spoiler blade 35 is further arranged above the isolation mesh ring 34 .

[0036] At least three spoiler blades 35 are provided and arranged in an array outside the mounting seat 21. The mounting seat 21 is sleeved on the top of the stirring shaft 31 and is located at the upper end of the isolation net.

[0037] A positioning frame 36 is further disposed at the bottom of the stirring shaft 31 , and a plurality of supporting legs 361 extend outward from the outer periphery of the positioning frame 36 .

[0038] The lower magnetic material 42 and the upper magnetic material 38 are permanent magnets.

[0039] A connecting hole 22 extends downward from the bottom of the cup cover 2 , and the mounting seat 21 is inserted into the connecting hole 22 . The stirring shaft 31 is detachably mounted on the cup cover 2 .

[0040] Working principle: The driving mechanism in this case uses magnetic material as the power drive, which is different from the traditional electric drive method. Among them, the driving mechanism includes a driving motor installed at the bottom of the outer body of the cup, and a lower magnetic material connected to the main shaft of the driving motor. Corresponding to the position of the lower magnetic material, an upper magnetic material is installed at the bottom of the stirring head of the stirring assembly through a fixed seat. The upper magnetic material and the lower magnetic material attract each other. The driving motor is started and the lower magnetic material is driven to rotate through the main shaft. Under the action of magnetic force, the stirring head is driven to rotate through the upper magnetic material, thereby realizing the frothing operation of the milk. The magnetic drive design not only reduces noise and avoids wear caused by traditional mechanical connections, but also simplifies the structure of the driving mechanism, with low cost and high cost performance.

[0041] In the above-mentioned stirring assembly, the stirring head is suspended at the bottom of the cup cover and has no direct contact with the cup body, thereby reducing wear on the cup body and other parts, while also reducing rotational friction, making the magnetic mechanism drive operation lighter and more stable.

[0042] In addition, when the stirring head rotates and stirs, it produces a greater mixing effect on the milk. The foamed milk and the unfoamed milk at the bottom of the cup are repeatedly mixed, thereby achieving uniform mixing of gas and liquid, avoiding the stratification phenomenon caused by uneven stirring in traditional frothers, and forming a more stable milk foam.

[0043] In addition, a mesh ring is installed above the stirring head. The upper and lower end surfaces of the mesh ring are provided with flow guide holes. A dividing net is installed to cover the flow guide holes. The mesh ring is coaxially connected to the stirring head and rotates synchronously. When the milk and air are cut through the dividing net, the larger bubbles are cut into smaller bubbles, thus forming a denser and more uniform milk foam, which can significantly reduce the coarse bubbles in the milk foam, improve the fineness and stability of the milk foam, and meet users' higher demands for beverage quality.

[0044] Furthermore, a plurality of flow-pushing tables are provided at the bottom of the mesh separation ring, and the flow-pushing tables rotate synchronously with the stirring head and the mesh separation ring, bringing complex disturbances to the milk, further enhancing the mixing effect of air and milk, and accelerating the flow of milk foam, prompting the milk foam to pass through the dividing net for multiple cuttings, thereby forming more delicate milk foam, avoiding the phenomenon of gas-liquid stratification, and ensuring the uniformity of the milk foam. A flow-turbulating blade is also provided above the mesh separation ring to guide the milk above the mesh separation ring, so that the upper layer of milk can flow in an orderly manner and continuously and stably enter the dividing net for cutting, ensuring that all liquid milk is fully mixed, further improving the efficiency of bubble cutting, and enhancing the uniformity of milk foam.

[0045] The stirring component in this case is inserted into the bottom of the cup cover through a mounting base. The stirring component can be detachably assembled and disassembled from the cup cover. The user can easily disassemble and clean the stirring component, avoiding the accumulation of milk foam residue in the stirring component, solving the problem of difficulty in cleaning the stirring component, and ensuring the cleanliness of the frother.

[0046] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
