Description

Technical Field

[0001] This utility model relates to the field of milk frother technology, and in particular to a novel milk frother. Background Technology

[0002] Existing milk frothers are generally divided into steam-type and mechanical-type. Steam-type milk frothers typically use a steam pipe to deliver steam to a container of milk, thereby creating milk foam. Mechanical-type milk frothers use a stirrer that rotates at an appropriate speed in the container of milk, quickly incorporating and mixing air into the milk to form milk foam.

[0003] Existing mechanical milk frothers typically use magnetic agitation for stirring. The milk frother includes a main unit, a cup body mounted on the main unit, and a stirring head mounted inside the cup body. The main unit contains a motor with a rotor on its output shaft and a driving magnet on the rotor. The bottom wall of the cup body has a positioning post, and the stirring head is fitted onto the positioning post to form a rotational engagement. A driven magnet is located at the bottom of the stirring head. The motor drives the rotor to rotate, and the rotor, through magnetic attraction, drives the stirring head to rotate, thereby causing the milk contained in the cup body to rotate, thus achieving the function of frothing milk.

[0004] When the stirring head is fitted onto the positioning post, the two are in direct contact, which can easily cause wear and tear over time, reducing the service life of the parts. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, the present invention provides a novel milk frother. By setting a first magnet and a second magnet with the same magnetic pole on the mounting column and the stirring bracket respectively, the principle of magnetic repulsion between like magnets is utilized to minimize the contact area between the two, thereby reducing the friction between them, reducing wear and tear, and extending the service life of the parts.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A new type of milk frother includes:

[0008] The main unit contains a drive magnet.

[0009] The cup body is mounted on the main unit; a rotatable stirring bracket is placed inside the cup body, and the stirring bracket is provided with a driven magnet opposite to the magnetic pole of the driving magnet and a stirring spring for frothing milk.

[0010] The cup body has a protruding mounting post on its inner bottom wall, and the stirring bracket has a fitting groove for fitting onto the mounting post to form a rotational fit. The top of the mounting post is provided with a first magnet, and the stirring bracket is also provided with a second magnet with the same magnetic pole as the first magnet at the position corresponding to the first magnet.

[0011] Furthermore, the stirring support includes a first support column and a support platform disposed at the bottom of the first support column, wherein:

[0013] The driven magnet is installed inside the support platform;

[0014] The stirring spring is installed on the outer peripheral surface of the support platform;

[0015] The second magnet is installed inside the first support column.

[0016] Furthermore, it also includes a cover plate, and the support platform has a first mounting groove for placing the driven magnet inside, and the cover plate is placed on the bottom of the support platform to fix the driven magnet in the first mounting groove.

[0017] Furthermore, it also includes a clamping ring that passes through the stirring spring, and the outer peripheral surface of the support platform is provided with a second mounting groove that extends circumferentially, and the clamping ring clamps and fixes the stirring spring in the second mounting groove.

[0018] Furthermore, it also includes a first cap, and the top of the first support column is provided with a third mounting groove for placing the second magnet. The first cap is placed on the top of the first support column to fix the second magnet in the third mounting groove.

[0019] Furthermore, it also includes a second cap, on which a first magnet is placed at the top of the mounting post, and the second cap covers the top of the mounting post and limits and fixes the first magnet.

[0020] Furthermore, a flow-dispersing support is placed inside the cup body, located at the upper end of the stirring support, and the flow-dispersing support is surrounded by several metal meshes for cutting milk foam.

[0022] Furthermore, limiting strips are provided on both sides of the end of the support bar away from the second support column, extending circumferentially. 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 limiting strips and the arc surface can be used to achieve limiting and fixing.

[0023] Furthermore, the second support column, the plurality of support bars, and the plurality of limiting bars are all integrally formed.

[0024] In summary, the novel milk frother provided by this utility model has the following beneficial effects:

[0034] 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.

[0035] 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.

[0036] 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.

[0037] See Figure 1-5 This utility model provides a novel milk frother, including a main unit (not shown in the figure) and a cup body 1 disposed on the main unit. The main unit is provided with a driving magnet and a driving motor for driving the driving magnet to rotate. The cup body 1 is provided with a rotatable stirring bracket 2. The stirring bracket 2 is provided with a driven magnet 3 opposite to the magnetic pole of the driving magnet and a stirring spring 5 for frothing milk.

[0038] Therefore, 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 5 on the stirring bracket 2 to rotate to stir the milk. When stirring the milk, the milk is in full contact with the stirring spring 5 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.

[0039] The cup body 1 has a protruding mounting post 102 on its inner bottom wall, and the stirring bracket 2 has a sleeve groove for fitting onto the mounting post 102 to form a rotational fit. The top of the mounting post 102 is provided with a first magnet 9, and the stirring bracket 2 is also provided with a second magnet 7 with the same magnetic pole as the first magnet 9 at the position corresponding to the first magnet 9.

[0040] Therefore, by setting a first magnet 9 and a second magnet 7 with the same magnetic poles on the mounting column 102 and the stirring bracket 2 respectively, the principle of magnetic repulsion between like magnets can be utilized to minimize the contact area between the two, thereby reducing the friction between them, reducing wear and extending the service life of the parts.

[0041] For details, please refer to Figure 1-2 The stirring bracket 2 includes a first support column 201 and a support platform 202 disposed at the bottom of the first support column 201. A first through groove 2021 is formed in the middle of the support platform 202. A second groove 2011 is formed inside the first support column 201. The first groove 2021 and the second groove 2011 are interconnected and form the aforementioned socket groove. The driven magnet 3 is installed inside the support platform 202. The stirring spring 5 is installed on the outer circumferential surface of the support platform 202. The second magnet 7 is installed inside the first support column 201.

[0042] More specifically, it also includes a cover plate 4. The support platform 202 has a first mounting groove 2022 for placing the driven magnet 3 inside. The cover plate 4 covers the bottom of the support platform 202 to fix the driven magnet 3 in the first mounting groove 2022. Preferably, there are multiple driven magnets 3, which are arranged around the outer periphery of the first groove 2021 at intervals.

[0043] In this embodiment, four driven magnets 3 are provided, and the number of the first mounting slot 2022 and the number of the driving magnet are the same as the number of driven magnets 3.

[0044] More specifically, it also includes a clamping ring 6 passing through the stirring spring 5. The outer circumferential surface of the support platform 202 has a second mounting groove 2023 extending circumferentially, and the clamping ring 6 clamps and fixes the stirring spring 5 in the second mounting groove 2023. Preferably, the clamping ring 6 is an elastic clamping ring.

[0045] More specifically, it also includes a first cap 8, the top of which has a third mounting groove 2012 for placing the second magnet 7, and the first cap 8 covers the top of the first support column 201 to fix the second magnet 7 in the third mounting groove 2012.

[0046] More specifically, it also includes a second cap 10, on which a first magnet 9 is placed at the top of the mounting post 102, and the second cap 10 covers the top of the mounting post 102 and limits and fixes the first magnet 9.

[0047] Therefore, when the product needs to be assembled, the first magnet 9 can be placed on the top of the mounting column 102 and fixed by covering it with the second cap 10; then the second magnet 7 can be placed in the third mounting groove 2012 on the top of the first support column 201 and fixed by covering it with the first cap 8; finally, the stirring bracket 2 can be sleeved on the mounting column 102 to achieve a rotatable connection in the cup body 1. At this time, the first magnet 9 and the second magnet 7 are opposite to each other and repel each other, thereby reducing the contact area between the two, thus reducing the wear between them and extending the service life of the parts.

[0048] See Figure 3 and Figure 5 The cup body 1 also contains a baffle 11 located at the upper end of the stirring support 2, and the baffle 11 is provided with several metal meshes 12 for cutting milk foam.

[0049] Therefore, by setting several metal meshes 12 on the baffle bracket 11, when the stirring spring 5 is rotated to drive the milk to rotate, the milk undergoes centrifugal motion. Subsequently, when the milk hits the metal meshes 12, the mesh holes on the metal meshes 12 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.

[0050] Specifically, the spoiler bracket 11 includes a second support column 1101 and a plurality of support bars 1102 spaced around the outer periphery of the second support column 1101. The support bars 1102 are provided with a fourth mounting groove 11021 for mounting the metal mesh 12, which is arranged vertically.

[0051] Therefore, when the milk impacts the vertically arranged metal mesh 12, the metal mesh 12 can more directly intercept the flowing milk and generate concentrated and unidirectional shearing force to cut the milk foam, thereby quickly cutting large milk foam into small milk foam. Moreover, the vertically arranged metal mesh 12 has a simpler structure and lower processing cost.

[0052] In this embodiment, three support bars 1102 are arranged at circumferential intervals, and three metal mesh sheets 12 are also provided and respectively installed on the fourth mounting grooves 11021 of the three support bars 1102.

[0053] Additionally, see Figure 4 Limiting strips 1103 are provided on both sides of the end of the support strip 1102 away from the second support column 1101 in a circumferential direction. The inner circumferential surface of the cup body 1 forms an inwardly contracting arc surface 101. When the turbulence bracket 11 is placed inside the cup body 1, the limiting strip 1103 and the arc surface 101 can be abutted and engaged to achieve limiting and fixing.

[0054] In this embodiment, the second support column 1101, several support bars 1102, and several limiting bars 1103 are all integrally formed.

[0055] In summary, the novel milk frother provided by this utility model has the following beneficial effects:

[0056] (I) The milk frother of this utility model sets a first magnet 9 and a second magnet 7 with the same magnetic pole on the mounting column 102 and the stirring bracket 2 respectively. By utilizing the principle of mutual repulsion between magnets of the same pole, the contact area between the two can be reduced to the greatest extent, thereby reducing the friction between the two, thus reducing the wear between the two and extending the service life of the parts.

[0057] (II) In the milk frother of this utility model, when the milk hits the vertically arranged metal mesh 12, the metal mesh 12 can more directly intercept the flowing milk and generate a concentrated and unidirectional shearing force to cut the milk foam, thereby quickly cutting the large milk foam into small milk foam. The vertically arranged metal mesh 12 has a simpler structure and lower processing cost.

[0058] 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.
