DETAILED DESCRIPTION

[0043] In order to make the technical problem solved by the present invention, the technical solution adopted and the technical effect achieved more clearly, the technical solution of the present invention is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0044] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0046] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0047] In the description of this embodiment, unless otherwise specified, the term "plurality" refers to a quantity of two or more than two.

[0048] like Figure 1-Figure 12 As shown, this embodiment provides a stirring and spoiling device, which can prevent the stirring and spoiling device from falling and injuring the user when the user pours milk foam, thereby reducing safety hazards; at the same time, the stirring and spoiling device can be disassembled for easy cleaning, thereby improving user experience.

[0049] like Figure 5-Figure 8As shown, this embodiment provides a stirring and turbulent device, which is arranged at the bottom of the milk frother body 100 and is used to stir and turbulent the milk in the milk frother body 100. The stirring and turbulent device mainly includes an ejector assembly 300, a paddle assembly 400 and a turbulent assembly 500. Among them, the ejector assembly 300 is arranged in the milk frother body 100 and is fixedly connected to the bottom wall of the milk frother body 100. The paddle assembly 400 is sleeved on the ejector assembly 300, and the paddle assembly 400 can rotate around the ejector assembly 300. The spoiler assembly 500 is magnetically connected to the ejector pin assembly 300, and the spoiler assembly 500 is located above the paddle assembly 400. The magnetic attraction between the spoiler assembly 500 and the ejector pin assembly 300 is greater than the sum of the gravity of the spoiler assembly 500 and the gravity of the paddle assembly 400. The magnetic attraction between the spoiler assembly 500 and the ejector pin assembly 300 is greater than the centrifugal force of the rotation of the paddle assembly 400, so that the spoiler assembly 500 can remain stationary when the paddle assembly 400 stirs the milk.

[0050] Based on the above design, in this embodiment, the ejector assembly 300 is welded or integrally formed with the bottom wall of the milk foam machine body 100. The paddle assembly 400 is sleeved on the ejector assembly 300 and can rotate relative to the ejector assembly 300, thereby achieving the stirring effect on the milk in the milk foam machine body 100. The spoiler assembly 500 is magnetically connected to the ejector assembly 300 and is located above the paddle assembly 400. At the same time, the magnetic attraction between the spoiler assembly 500 and the ejector assembly 300 is greater than the centrifugal force of the paddle assembly 400. In this way, when the paddle assembly 400 stirs the milk, the milk is stirred and rotated by the centrifugal force of the paddle assembly 400. In other words, the centrifugal force of the stirring assembly on the milk is less than the magnetic attraction between the spoiler assembly 500 and the ejector assembly 300. Therefore, when the stirring assembly stirs the milk, the spoiler assembly 500 can remain relatively stationary with the ejector assembly 300, thereby achieving the effect of "the paddle assembly 400 rotates and the spoiler assembly 500 does not move". It can be understood that when the paddle assembly 400 rotates and drives the milk to rotate, the spoiler assembly 500 does not move, so that the spoiler assembly 500 can achieve a spoiler effect on the rotating milk, thereby minimizing or avoiding the occurrence of vortices inside the milk, so that the milk foam produced by the milk frother is denser and more delicate, which is convenient for latte art.

[0051] Compared with the prior art, the stirring and spoiling device in this embodiment has a simple structure, the spoiler assembly 500 is magnetically connected to the ejector assembly 300, and the magnetic attraction between the spoiler assembly 500 and the ejector assembly 300 is greater than the sum of the gravity of the spoiler assembly 500 and the gravity of the paddle assembly 400. In this way, when the user pours out the milk foam, the spoiler assembly 500 and the ejector assembly 300 can still be stably magnetically connected, avoiding the phenomenon that the spoiler assembly 500 and the paddle assembly 400 fall and injure the user, thereby reducing safety hazards. At the same time, the magnetic attraction between the spoiler assembly 500 and the ejector assembly 300 is greater than the centrifugal force of the paddle assembly 400, so that when the paddle assembly 400 stirs the milk, the spoiler assembly 500 can remain stationary, so that the spoiler assembly 500 can achieve the effect of spoiling the rotating milk, making the produced milk foam more delicate and dense.

[0052] In addition, when the user needs to clean the stirring spoiler device, the user only needs to lift the spoiler assembly 500 to release the magnetic connection between the spoiler assembly 500 and the ejector assembly 300, thereby facilitating the removal of the spoiler assembly 500 and the paddle assembly 400 for cleaning. It should be noted that the upward lifting force of the spoiler assembly 500 by the user is greater than the magnetic attraction between the spoiler assembly 500 and the ejector assembly 300, which facilitates the disassembly and cleaning of the spoiler assembly 500 and the paddle assembly 400 and improves the user experience.

[0053] like Figure 7-Figure 8 As shown, in this embodiment, the ejector assembly 300 includes an ejector fixing member 310 and an ejector sleeve 320. The ejector fixing member 310 is fixedly connected to the bottom wall of the milk frother body 100. The ejector sleeve 320 is set on the ejector fixing member 310 and has an interference fit with the ejector fixing member 310. The spoiler assembly 500 is connected to the ejector sleeve 320.

[0054] Specifically, the ejector fixing member 310 in this embodiment can be fixed to the bottom wall of the milk frother body 100 by welding or riveting. The ejector fixing member 310 is cylindrical, which is convenient for the rotation of the paddle assembly 400, and is made of metal material to improve strength and extend service life. The ejector sleeve 320 is set on the ejector fixing member 310 and has an interference fit with the ejector fixing member 310, thereby preventing milk from entering the gap between the ejector fixing member 310 and the ejector sleeve 320, thereby extending service life.

[0055] For further information, please refer to Figure 9-11 The outer peripheral side of the ejector sleeve 320 is polygonal, and the spoiler assembly 500 includes a spoiler blade 510 and a first connecting column 520. The spoiler blade 510 is arranged on the outer peripheral side of the first connecting column 520. The first connecting column 520 is provided with a first countersunk hole 530. The inner wall of the first countersunk hole 530 is polygonal, and the first countersunk hole 530 is sleeved on the outer peripheral side of the ejector sleeve 320.

[0056] Optionally, the outer peripheral side of the ejector sleeve 320 in this embodiment is an outer hexagon, the inner wall of the first counterbore 530 is an inner hexagon, and the spoiler assembly 500 is sleeved with the ejector sleeve 320 through the first counterbore 530, thereby preventing the spoiler assembly 500 from rotating relative to the ejector sleeve 320. Of course, the operator can also set the outer peripheral side of the ejector sleeve 320 and the inner peripheral side of the first counterbore 530 to other non-circular structures, so as to achieve the effect of preventing the spoiler assembly 500 from rotating.

[0057] Please continue to refer to Figure 7-Figure 8 In this embodiment, the first connecting column 520 is further provided with a second counterbore 540, and a first adsorption block 550 is provided in the second counterbore 540; a second adsorption block 330 is provided in the ejector sleeve 320, and the first adsorption block 550 is magnetically connected to the second adsorption block 330. Exemplarily, the first adsorption block 550 and the second adsorption block 330 can both be configured as magnets, and the magnetism of the two can be opposite, or one of the first adsorption block 550 and the second adsorption block 330 can be configured as a magnet, and the other can be configured as an iron block.

[0058] Optionally, the first adsorption block 550 and the second adsorption block 330 in this embodiment are arranged opposite to each other, thereby improving the magnetic attraction between the spoiler assembly 500 and the ejector sleeve 320 and ensuring the stability and reliability of the magnetic attraction between the two.

[0059] Optionally, the magnetic flux density between the first adsorption block 550 and the second adsorption block 330 in this embodiment is not less than 100 mT, ensuring that the paddle assembly 400 and the spoiler assembly 500 will not fall off when the user pours milk foam.

[0060] Optionally, both the first adsorption block 550 and the second adsorption block 330 in the present embodiment can be provided in plurality, and the plurality of first adsorption blocks 550 and the plurality of second adsorption blocks 330 are provided in one-to-one correspondence.

[0061] Optionally, the number of spoiler blades 510 in this embodiment is multiple, and the multiple spoiler blades 510 are evenly arranged about the axis of the first connecting column 520, thereby improving the spoiler effect of the spoiler blades 510 and reducing or avoiding the phenomenon of vortex generation in the rotating milk.

[0062] For example, the spoiler blades 510 in this embodiment can be set to three, four or five pieces. The inclination angle of each spoiler blade 510 is set between 35° and 55°, the height of the spoiler blade 510 is set between 12mm and 16mm, the curvature of the spoiler blade 510 is set between 0° and 8°, and the gap between the spoiler blade 510 and the inner wall of the milk frother body 100 is set between 1mm and 3mm. Of course, the operator can also set the spoiler blades 510 to other quantities and sizes according to actual needs, which will not be repeated here.

[0063] Please continue to refer to Figure 7-Figure 8 In this embodiment, the spoiler assembly 500 further includes a lifting member 560, which is connected to an end of the first connecting column 520 away from the blade assembly 400. The provision of the lifting member 560 can facilitate the user to take and place the spoiler assembly 500, and facilitate operation.

[0064] Please continue to refer to Figure 7-Figure 8 In this embodiment, a first clamping rib 570 is convexly disposed on the outer wall of the first connecting column 520, and the blade assembly 400 includes a second connecting column 410 and a second clamping rib 420. The second connecting column 410 is sleeved on the ejector assembly 300, and the second clamping rib 420 is disposed on the inner wall of the second connecting column 410. In the height direction of the ejector assembly 300, the projection area of ​​the first clamping rib 570 is larger than the projection area of ​​the second clamping rib 420, and the first clamping rib 570 passes through the second clamping rib 420 and is located below the second clamping rib 420. By disposing the first clamping rib 570 and the second clamping rib 420, the blade assembly 400 and the spoiler assembly 500 are buckled and connected, so that when the user lifts the spoiler assembly 500, the first clamping rib 570 and the second clamping rib 420 can limit each other, so that the blade assembly 400 can also be lifted and taken out together. The first clamping rib 570 and the second clamping rib 420 are made of silicone material. When the user needs to separate the spoiler assembly 500 and the blade assembly 400, the user only needs to apply force in opposite directions to the two to pull the first clamping rib 570 out of the second connecting column 410, which is easy to operate.

[0065] Further, in this embodiment, a plurality of first clamping ribs 570 are provided, and the plurality of first clamping ribs 570 are evenly arranged about the axis of the first connecting column 520. For example, the first clamping ribs 570 can be provided in three, four, five, etc. The second clamping rib 420 is annular, the second clamping rib 420 is coaxially arranged with the second connecting column 410, and the first connecting column 520 and the second connecting column 410 are coaxially arranged, so as to improve the coaxiality of the spoiler assembly 500 and the blade assembly 400 and avoid tilting.

[0066] Furthermore, if Fig.12As shown, in this embodiment, a preset distance a is maintained between the first clamping rib 570 and the inner wall of the second connecting column 410, and a preset distance b is maintained between the first clamping rib 570 and the second clamping rib 420; the blade assembly 400 includes a third connecting column 430, which is sleeved on the ejector assembly 300, and the third connecting column 430 is connected to the second connecting column 410 and is located below the second connecting column 410, and a preset distance c is maintained between the first connecting column 520 and the third connecting column 430. In addition, when the first clamping rib 570 is inserted into the second connecting column 410 and the first clamping rib 570 is located below the second clamping rib 420, a gap is also maintained between the outer peripheral side of the first connecting column 520 and the second clamping rib 420. By setting the above-mentioned gaps, a certain gap can be maintained between the spoiler assembly 500 and the blade assembly 400 in both the height direction and the circumferential direction (it can be understood that the spoiler assembly 500 is supported by the top of the ejector sleeve 320), that is, the spoiler assembly 500 and the blade assembly 400 do not contact each other, thereby preventing the non-rotating spoiler assembly 500 from interfering with the rotating blade assembly 400, and also avoiding the generation of noise.

[0067] Exemplarily, the preset distance a in this embodiment can be set to 0.2 mm and above, the preset distance b can be set to 0.6 mm and above, the preset distance c can be set to 0.5 mm and above, and so on.

[0068] Optionally, the diameter of the stirring and turbulent device in this embodiment is between 1 / 3 and 1 / 2 of the diameter of the bottom of the milk frother body 100 .

[0069] The present embodiment further provides a milk frother, which includes a milk frother body 100 and the stirring and disturbing device, wherein the stirring and disturbing device is disposed at the bottom of the milk frother body 100 and is used to stir and disturb the milk in the milk frother body 100. When a user uses the milk frother to pour out milk foam, the stirring and disturbing device can be prevented from being poured out and injuring the user, thereby improving safety; meanwhile, the stirring and disturbing device is easy to disassemble, thereby improving user experience and saving costs.

[0070] Specifically, if Figure 1-Figure 4 , Fig.12As shown, the milk frothing machine comprises a base 200, a milk frothing machine body 100 and the above-mentioned stirring and turbulent device. A driving assembly 210 is arranged inside the base 200, and the output shaft of the driving assembly 210 is connected to a driving turntable 220, and a first magnet 230 is arranged on the driving turntable 220. The milk frothing machine body 100 is detachably connected to the base 200, and an ejector assembly 300 is arranged inside the milk frothing machine body 100, and the ejector assembly 300 is fixedly connected to the bottom wall of the milk frothing machine body 100. The stirring and turbulent device comprises a paddle assembly 400, and the paddle assembly 400 is sleeved on the ejector assembly 300, and the paddle assembly 400 maintains a preset distance m from the bottom wall of the milk frothing machine body 100; a second magnet 440 is arranged inside the paddle assembly 400, and the second magnet 440 is used to be magnetically connected to the first magnet 230.

[0071] Based on the above design, in this embodiment, through the magnetic attraction of the first magnet 230 and the second magnet 440, when the driving assembly 210 drives the driving turntable 220 to rotate, the paddle assembly 400 can rotate synchronously, thereby achieving the function of the driving assembly 210 indirectly driving the paddle assembly 400 to rotate. Among them, the paddle assembly 400 maintains a preset distance m from the bottom wall of the milk frother body 100, which is conducive to the smooth rotation of the paddle assembly 400 and avoids interference between the paddle assembly 400 and the bottom wall of the milk frother body 100.

[0072] Compared with the prior art, the milk frother in this embodiment has a simple structure. Through the arrangement of the base 200, the milk frother body 100 and the paddle assembly 400, the base 200 is detachably connected to the milk frother body 100. The driving assembly 210 is arranged in the base 200. The driving assembly 210 drives the driving turntable 220 to rotate. The first magnet 230 arranged in the driving turntable 220 and the paddle assembly 400 in the milk frother body 100 are provided with a second magnet 440. Through the magnetic attraction of the first magnet 230 and the second magnet 440, when the driving assembly 210 drives the driving turntable 220 to rotate, the paddle assembly 400 can rotate synchronously, thereby realizing the effect of the driving assembly 210 indirectly driving the paddle assembly 400 to rotate. The milk in the milk frother body 100 will not enter the driving assembly 210 in the base 200, thereby playing a certain protective role on the driving assembly 210, extending the service life of the driving assembly 210, and improving the safety performance. In addition, the driving assembly 210 in this embodiment does not occupy the space in the milk frother body 100, so the user can prepare more milk froth, thereby improving the user experience.

[0073] The milk frother body 100 and the base 200 in this embodiment are detachably connected, so that after the user has made the milk froth, the milk frother body 100 can be removed from the base 200, thereby improving the flexibility of use.

[0074] Optionally, the driving component 210 in this embodiment can be configured as a motor.

[0075] Optionally, the first magnet 230 and the second magnet 440 in this embodiment are both set to be multiple. For example, the first magnet 230 and the second magnet 440 are both set to be four, five, six, etc. The first magnet 230 and the second magnet 440 correspond to each other one by one, and the first magnet 230 and the second magnet 440 have opposite magnetic properties.

[0076] Optionally, the spacing between the first magnet 230 and the second magnet 440 in this embodiment is set to be between 3 mm and 6 mm. When the spacing between the first magnet 230 and the second magnet 440 is less than 3 mm, the starting torque of the driving assembly 210 required by the paddle assembly 400 will increase; and when the spacing between the first magnet 230 and the second magnet 440 is greater than 6 mm, the speed of the driving assembly 210 required by the paddle assembly 400 will increase, and the increase in the torque and speed of the driving assembly 210 will reduce its service life. Therefore, considering comprehensively that the spacing between the first magnet 230 and the second magnet 440 is set to be between 3 mm and 6 mm, it is possible to produce milk foam that meets the requirements while extending the service life of the driving assembly 210.

[0077] like Figure 2-Figure 4 As shown, a heating plate 240 is also provided in the base 200 in this embodiment, and the heating plate 240 is used to heat the milk in the milk frother body 100, so as to prepare milk froth drinks of different temperatures. Optionally, the heating temperature range of the heating plate 240 can be set between 50°C and 80°C. The heating plate 240 is electrically connected to the central control screen on the base 200, and the user can selectively decide whether to enable the heating plate 240.
