Abstract
Description
Technical Field
[0001] This utility model relates to the field of milk frother technology, and in particular to a milk frother with good foaming effect. Background Technology
[0002] A milk frother works by adding a stirring device to a container to continuously agitate the milk, while a heating element simultaneously creates bubbles. Currently, most milk frothers on the market only have a single spring agitator, which produces milk foam that is not fine enough. When making latte art, the foam lacks fluidity, resulting in poor latte art effects.
[0003] To address the aforementioned issues, patent application number 201820504345.4 discloses a milk frother, which includes a main unit, a cup body, and a cup lid. The cup body is equipped with a stirring device, which includes a support frame, a stirrer, a stirring spring, and a baffle. The baffle can turbulent the milk being stirred by the stirrer, resulting in a more thorough milk frothing effect and finer milk foam.
[0004] However, in actual use, it was found that because the swivel holes on the spoiler are elongated and have a large area, they cannot cut large milk foam into smaller milk foam, and the fluidity is still poor, which still cannot meet the needs of latte art. Utility Model Content
[0005] In order to overcome at least one of the defects mentioned above in the prior art, the present invention provides a milk frother with good foaming effect. By setting a metal mesh on the turbulence support, when the milk undergoes centrifugal motion and impacts the metal mesh, the mesh holes on the metal mesh can cut large milk foam into small milk foam, thereby improving the fluidity of the milk and making it easier to create latte art.
[0006] The technical solution adopted by this utility model to solve its problem is:
[0007] A milk frother with good foaming effect includes a main unit and a cup body disposed on the main unit, wherein:
[0008] The main unit is equipped with a driving magnet inside, and a rotatable stirring bracket is placed inside the cup. The stirring bracket is equipped with a driven magnet with the opposite magnetic pole to that of the driving magnet. The stirring bracket is also equipped with a stirring spring for frothing milk.
[0009] The cup body also contains a baffle support that covers the upper end of the stirring support, and the baffle support is provided with at least two metal meshes for cutting milk foam.
[0010] Further, the spoiler bracket includes a first support rod extending in the vertical direction, a support ring surrounding the outer periphery of the first support rod, and a support strip with one end connected to the outer peripheral surface of the first support rod and the other end connected to the inner peripheral surface of the support ring, wherein:
[0011] The support bars are provided in multiple forms, and the multiple support bars are arranged at intervals along the circumferential direction;
[0012] The two adjacent support bars, the first support rod, and the support ring together form an installation space for installing the metal mesh.
[0013] Furthermore, the support bars are inclined relative to the axis of the first support rod, and the inclination direction of multiple support bars relative to the axis of the first support rod is the same.
[0014] The two sides of the metal mesh are respectively connected to the opposite sides of the two adjacent support bars, and the two ends of the metal mesh are respectively connected to the outer peripheral surface of the first support rod and the inner peripheral surface of the support ring so that the metal mesh is set in a horizontally inclined position.
[0015] Furthermore, the outer circumferential surface of the support ring is also provided with a protrusion, and the inner circumferential surface of the cup body forms an inwardly contracting arc surface. When the turbulence bracket is placed inside the cup body, the protrusion and the arc surface can be engaged to achieve limiting and fixing.
[0016] Furthermore, the inner bottom of the cup body is provided with a mounting post, and the stirring bracket includes a second support rod extending in the vertical direction. The interior of the second support rod is provided with a sleeve groove for fitting onto the mounting post to form a rotational fit.
[0017] Furthermore, the stirring bracket also includes a support platform disposed at the bottom of the second support rod, and the support platform has a through groove that connects to the sleeve groove and allows the mounting column to pass through.
[0018] Furthermore, multiple driven magnets are provided, and the bottom of the support platform is provided with multiple first mounting slots corresponding to the number of the multiple driven magnets. The multiple first mounting slots are arranged around the outer periphery of the through slot and spaced apart in the circumferential direction.
[0019] Furthermore, it also includes a cover plate disposed on the bottom of the support platform, the cover plate being used to seal the plurality of first mounting slots to achieve the restraint and fixation of the driven magnet.
[0020] Furthermore, the stirring bracket also includes at least two support blocks arranged around the outer circumference of the second support rod and spaced apart from each other. The outer circumference of the support block is provided with a second mounting groove for installing the stirring spring, and the second mounting groove extends circumferentially.
[0021] Furthermore, it also includes an elastic retaining ring inserted inside the stirring spring, the elastic retaining ring being used to press and fix the stirring spring in the second mounting groove.
[0022] In summary, the milk frother with good foaming effect provided by this utility model has the following beneficial effects:
[0023] (1) The milk frother of this utility model sets several metal meshes on the turbulence support. When the stirring spring rotates and drives the milk to rotate, the milk undergoes centrifugal motion. Then, when the milk hits the metal meshes, the mesh holes on the metal meshes can cut the large milk bubbles on the milk into small milk bubbles, thereby making the milk frothing effect more complete, the milk bubbles more delicate, and the milk flow better, which makes it easier to make latte art.
[0024] (2) In the milk frother of this utility model, when the milk hits the horizontally inclined metal mesh, the metal mesh can change the flow direction of the milk to multiple angles to form a spiral or vortex path. This asymmetrical flow can generate more complex shearing force, thereby cutting the large air bubbles in the milk foam multiple times. In addition, the horizontally inclined metal mesh can not only prolong the contact time between the milk and the metal mesh, but also cut the air bubbles more evenly through the shearing force in multiple directions, making the milk foam more delicate and dense.

[0032] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.
[0033] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0035] See Figure 1-5 This utility model provides a milk frother with good foaming effect, including a main unit (not shown in the figure) and a cup body 1 set on the main unit. The main unit is provided with a driving magnet and a driving motor for driving the driving magnet to rotate. A rotatable stirring bracket 2 is placed inside the cup body 1. The stirring bracket 2 is provided with a driven magnet 3 with the opposite magnetic pole to the driving magnet. The stirring bracket 2 is also provided with a stirring spring 4 for frothing milk.
[0036] Based on the above structure, when the cup body 1 is placed on the main unit, the magnetic attraction between the driven magnet 3 in the stirring bracket 2 and the driving magnet in the main unit ensures that the driven magnet 3 and the driving magnet are vertically aligned. Then, when the main unit is started, the drive motor will drive the driving magnet to rotate, and through its magnetic attraction with the driven magnet 3, it will drive the stirring bracket 2 to rotate, which in turn will drive the stirring spring 4 on the stirring bracket 2 to rotate to stir the milk in the cup body 1. When stirring the milk, the milk is in full contact with the stirring spring 4 in the cup body 1, and the resulting vortex air pressure will continuously inject air into the milk to form rich foam, so that the milk can be fully foamed and the milk frothing effect is more complete.
[0037] However, the milk foam produced by the stirring spring 4 alone is not fine enough. When making latte art, the milk foam does not flow well enough, resulting in poor latte art effect. To address this, this application also places a baffle support 6 inside the cup body 1. The baffle support 6 covers the upper end of the stirring support 2, and the baffle support 6 is provided with at least two metal meshes 64 for cutting the milk foam.
[0038] Therefore, by setting several metal meshes 64 on the baffle support 6, when the stirring spring 4 is rotated to drive the milk to rotate, the milk undergoes centrifugal motion. Subsequently, when the milk hits the metal meshes 64, the mesh holes on the metal meshes 64 can cut the large milk bubbles on the milk into small milk bubbles, thereby making the milk frothing effect more thorough, the milk bubbles more delicate, and the milk flow better, which in turn makes it easier to create latte art.
[0039] For details, please refer to Figure 1-2 The spoiler bracket 6 includes a first support rod 61 extending in the vertical direction, a support ring 62 surrounding the first support rod 61 in a circular shape, and a support strip 63 with one end connected to the outer circumferential surface of the first support rod 61 and the other end connected to the inner circumferential surface of the support ring 62. Multiple support strips 63 are provided and are spaced apart in the circumferential direction. An installation space for installing a metal mesh 64 is formed between two adjacent support strips 63, the first support rod 61, and the support ring 62.
[0040] In this embodiment, four support bars 63 are arranged at circumferential intervals to form four installation spaces; two metal mesh sheets 64 are provided and are respectively arranged in two opposite installation spaces.
[0041] The support bar 63 is inclined relative to the axis of the first support rod 61, and the inclination direction of the multiple support bars 63 relative to the axis of the first support rod 61 is the same; the two sides of the metal mesh 64 are respectively connected to the opposite sides of the two adjacent support bars 63, and the two ends of the metal mesh 64 are respectively connected to the outer peripheral surface of the first support rod 61 and the inner peripheral surface of the support ring 62 so that the metal mesh 64 is arranged in a horizontally inclined position.
[0042] Therefore, when the milk undergoes centrifugal motion and rises, it can impact the horizontally inclined metal mesh 64. This metal mesh 64 can change the flow direction of the milk to multiple angles to form a spiral or vortex path. This asymmetrical flow can generate more complex shearing forces, thereby cutting the large air bubbles in the milk foam multiple times. In addition, the horizontally inclined metal mesh 64 can not only prolong the contact time between the milk and the metal mesh 64, but also cut the air bubbles more evenly through shearing forces in multiple directions, making the milk foam finer and denser.
[0043] See Figure 2 and Figure 4 The outer circumferential surface of the support ring 62 is also provided with a protrusion 621, and the inner circumferential surface of the cup body 1 forms an inwardly contracting arc surface 11. When the turbulence bracket 6 is placed inside the cup body 1, the protrusion 621 and the arc surface 11 can be abutted and engaged to achieve limiting and fixing.
[0044] With this setup, when milk frothing is needed, simply place the spoiler bracket 6 into the cup body 1 and press it down firmly so that the protrusion 621 abuts against the arc surface 11 to limit and fix the spoiler bracket 6. When it needs to be disassembled, the user only needs to grab the first support rod 61 and pull it upward to remove it. The assembly and disassembly are very convenient, which also makes cleaning easier.
[0045] See Figure 3 and Figure 5 The cup body 1 has a mounting post 12 protruding from its inner bottom. The stirring bracket 2 includes a second support rod 21 extending in the vertical direction and a support platform 22 at the bottom of the second support rod 21. The second support rod 21 has a sleeve groove inside, and the support platform 22 has a through groove 221 communicating with the sleeve groove.
[0046] Therefore, by fitting the sleeve groove and the through groove 221 onto the mounting post 12, the stirring bracket 2 can be rotatably mounted inside the cup body 1. In addition, the first support rod 61 of the turbulence bracket 6 also has an avoidance groove 611 inside. When the turbulence bracket 6 is placed into the cup body 1, the second support rod 21 extends into the avoidance groove 611 to prevent interference between the two.
[0047] The support platform 22 has multiple driven magnets 3 and multiple first mounting slots 222 corresponding to the number of driven magnets 3. The multiple first mounting slots 222 are arranged around the outer periphery of the through slot 221 and are spaced apart in the circumferential direction. In addition, a cover plate 7 is provided on the bottom of the support platform 22. The cover plate 7 is used to seal the multiple first mounting slots 222 to restrict and fix the driven magnets 3.
[0048] In this embodiment, four driven magnets 3 are provided, and they are spaced apart in a ring at the bottom of the support platform 22; the number of the first mounting groove 222 and the number of the driving magnets are the same as the number of driven magnets 3.
[0049] Furthermore, the stirring bracket 2 also includes a support block 23 that is arranged around the outer circumference of the second support rod 21 and above the support platform 22. There are two support blocks 23 arranged at intervals along the circumference. A second mounting groove 231 for mounting the stirring spring 4 is opened on the outer circumference of the support block 23. The second mounting groove 231 extends along the circumference.
[0050] In addition, it also includes an elastic retaining ring 5 that passes through the stirring spring 4. Under the elastic force of the elastic retaining ring 5, the stirring spring 4 can be pressed and fixed in the second mounting groove 231, thereby realizing the assembly and fixing of the stirring spring 4.
[0051] In summary, the milk frother with good foaming effect provided by this utility model has the following beneficial effects:
[0052] (I) The milk frother of this utility model has several metal meshes 64 set on the turbulence support 6. When the stirring spring 4 rotates and drives the milk to rotate, the milk undergoes centrifugal motion. When the milk hits the metal meshes 64, the mesh holes on the metal meshes 64 can cut the large milk bubbles on the milk into small milk bubbles, thereby making the milk frothing effect more complete, the milk foam more delicate, and the milk flow better, which makes it easier to make latte art.
[0053] (II) In the milk frother of this utility model, when the milk impacts the horizontally inclined metal mesh 64, the metal mesh 64 can change the flow direction of the milk to multiple angles to form a spiral or vortex path. This asymmetrical flow can generate more complex shearing forces, thereby cutting the large air bubbles in the milk foam multiple times. In addition, the horizontally inclined metal mesh 64 can not only prolong the contact time between the milk and the metal mesh 64, but also cut the air bubbles more evenly through shearing forces in multiple directions, making the milk foam more delicate and dense.
[0054] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
