Description

Technical Field

[0001] This utility model relates to the field of milk frother technology, specifically a planar electromagnetic heating milk frother. Background Technology

[0002] As consumers demand higher quality beverages, the market has placed greater demands on the heating efficiency, temperature control accuracy, and operational stability of milk frothers. Most existing milk frothers use electromagnetic heating to heat and foam milk in order to meet the need for rapid milk frothing.

[0003] Chinese patent document CN209269388U discloses a milk beverage heating and stirring machine, including a cup body, a stirrer, a base, a heating plate, a temperature measuring component, and a first lever assembly. The base has a receiving cavity at its upper end to accommodate the cup body, and the cavity wall has a first radial opening and a second radial opening. The heating plate is disposed at the bottom of the receiving cavity to heat the bottom of the cup body. The first lever assembly is rotatably disposed outside the receiving cavity, and a protrusion on its first end extends into the receiving cavity through the first radial opening. The first lever assembly is configured such that when the cup body is placed in the receiving cavity, the side wall of the cup body presses against the protrusion, and the second end of the first lever assembly pushes the temperature measuring component to contact the side wall of the cup body through the edge of the second radial opening into the receiving cavity for temperature measurement. The milk beverage heating and stirring machine provided by this invention can reduce the impact of the heating plate's heat on the temperature measuring component during continuous heating, improve the temperature measurement accuracy of the temperature measuring component during multiple consecutive heating cycles, and enhance the amount of foam and the taste of the milk.

[0004] In the above and existing technologies, many devices lack planar heating coils. If a bottom planar heating design is adopted, the electromagnetic waves generated by the electromagnetic coil may act on the motor, causing the motor to be accidentally heated. Overheating of the motor may affect its operating efficiency and service life.

[0005] Therefore, this utility model proposes a planar electromagnetic heating milk foam mixer to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a planar electromagnetic heating milk frother to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a planar electromagnetic heating milk frother, comprising a top support platform and a heating coil, wherein the heating coil is installed inside the top support platform; The bottom of the top support platform is provided with a rotating shaft assembly, a protective assembly, and a heat dissipation assembly. The rotating shaft assembly is located inside the heating coil, the protective assembly is located below the heating coil, and the heat dissipation assembly is located at the bottom of the protective assembly.

[0008] Preferably, a magnet is mounted on the magnet shaft in the rotating shaft assembly, and the magnet shaft is adapted to be snapped into the mounting head in the middle of the top support platform.

[0009] Preferably, the heating coil is fitted and snapped onto the top support platform, and a ferrite high-permeability magnetic core is provided at the bottom of the heating coil. A double-layer motor isolation copper ring is provided at the bottom of the ferrite high-permeability magnetic core, and the double-layer motor isolation copper ring is snapped onto the magnet shaft.

[0010] Preferably, the motor bracket in the protection assembly is located at the bottom of the double-layer motor isolation copper ring, and the sleeve in the middle of the motor bracket is sleeved and mounted on the magnet shaft.

[0011] Preferably, the bottom of the protection plate in the protection assembly is provided with a power board, the power board is provided with a snap-fit ​​protrusion, the top of the snap-fit ​​protrusion is snapped with a magnet shaft, and the bottom of the snap-fit ​​protrusion is snapped with a motor.

[0012] Preferably, a motor is placed inside the heat sink of the heat dissipation assembly, and a cooling fan is installed on the side of the heat sink.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By placing the motor at the bottom of the protective assembly and using an extended shaft structure, the motor is kept away from the heating coil area. At the same time, the ferrite high-permeability magnetic core at the bottom of the heating coil and the double-layer motor isolation copper ring provide double protection against electromagnetic waves, preventing the motor from being accidentally heated. This ensures the motor's operating efficiency and service life, eliminates the need for additional heat insulation steps, reduces costs, and improves equipment safety. The motor frame and protective plate in the protective assembly provide stable support for the internal structure, while the heat sink and cooling fan in the heat dissipation assembly can promptly remove excess heat generated during motor operation and heating, further ensuring the overall operational stability of the equipment, extending its service life, and meeting the market's high demands for heating efficiency, temperature control accuracy, and safety in milk frothers.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example 1: Please refer to Figures 1-2 A planar electromagnetic heating milk frother includes a top support platform 1 and a heating coil 2. The heating coil 2 is installed inside the top support platform 1. A rotating shaft assembly 3, a protective assembly 4, and a heat dissipation assembly 5 are installed at the bottom of the top support platform 1. The rotating shaft assembly 3 is located inside the heating coil 2, the protective assembly 4 is located below the heating coil 2, and the heat dissipation assembly 5 is located at the bottom of the protective assembly 4.

[0017] A magnet 302 is mounted on the magnet shaft 301 in the rotating shaft assembly 3, and the magnet shaft 301 is adapted to be snapped into the mounting head 303 in the middle of the top support platform 1.

[0018] The heating coil 2 is fitted onto the top support platform 1. A ferrite high-permeability magnetic core 304 is provided at the bottom of the heating coil 2. A double-layer motor isolation copper ring 305 is provided at the bottom of the ferrite high-permeability magnetic core 304. The double-layer motor isolation copper ring 305 is fitted onto the magnet shaft 301.

[0019] When in use, the device is started. The picture shows the details of the device's internal structure. First, the power board 404 supplies power to the heating coil 2. The heating coil 2 generates an alternating magnetic field under the control of the power board 404. This alternating magnetic field acts on the container that needs to be heated. At this time, the ferrite high-permeability magnetic core 304 at the bottom of the heating coil 2 plays a guiding role, optimizing the distribution of the alternating magnetic field, improving heating efficiency, and preventing excessive diffusion of the magnetic field. The double-layer motor isolation copper ring 305 is snapped onto the magnet shaft 301, which can effectively block the electromagnetic waves generated by the heating coil 2 from being transmitted downward, providing protection for the components in the lower protection component 4 and heat dissipation component 5. The magnet shaft 301 in the rotating shaft assembly 3 is snapped into the mounting head 303 in the middle of the top support platform 1. Throughout the process, the top support platform 1 provides stable support for the heating coil 2 and the rotating shaft assembly 3, ensuring that the heating process proceeds in an orderly manner.

[0020] Example 2: Based on Example 1, please refer to... Figures 2-3 The motor bracket 401 in the protection component 4 is located at the bottom of the double-layer motor isolation copper ring 305, and the sleeve 402 in the middle of the motor bracket 401 is sleeved and installed on the magnet shaft 301.

[0021] The bottom of the protection plate 403 in the protection component 4 is provided with a power board 404, and the power board 404 is provided with a snap-fit ​​protrusion 405. The top of the snap-fit ​​protrusion 405 is snapped with a magnet shaft 301, and the bottom of the snap-fit ​​protrusion 405 is snapped with a motor 406.

[0022] In use, based on Embodiment 1, the protection component 4 begins to play a core role. The motor bracket 401 at the bottom of the double-layer motor isolation copper ring 305 is sleeved onto the magnet shaft 301 through the middle sleeve 402. This not only limits and fixes the lower end of the magnet shaft 301 to prevent it from shifting during operation, but also provides a mounting base for the entire protection component 4. The protection plate 403 below the motor bracket 401 provides heat insulation to prevent it from affecting the operation of the power board 404 and the motor 406. The power board 404 is fixed to the bottom of the protection plate 403, and the top of the snap-fit ​​protrusion 405 on it snaps into the magnet shaft 301, further... The installation stability of the magnet shaft 301 is reinforced to ensure that the magnet shaft 301 will not shift due to vibration. The bottom of the snap-fit ​​protrusion 405 snaps into the motor 406, achieving precise positioning and installation of the motor 406. At this time, the motor 406 is at the bottom of the protective component 4, away from the area where the heating coil 2 is located. At the same time, with the blocking effect of the double-layer motor isolation copper ring 305, the electromagnetic waves generated by the heating coil 2 are effectively prevented from acting on the motor 406, preventing the motor 406 from being accidentally heated and ensuring that the motor 406 can output power stably. At the same time, the coordinated support of the protective plate 403 and the motor frame 401 also makes the internal structure of the equipment more stable.

[0023] Example 3: Based on Example 2, please refer to... Figures 3-4The heat sink 501 in the heat sink assembly 5 contains a motor 406, and a cooling fan 502 is installed on the side of the heat sink 501.

[0024] In use, based on Embodiment 2, the heat dissipation component 5 starts operating, and the motor 406 is placed inside the heat dissipation block 501 in the heat dissipation component 5. The heat dissipation block 501 can quickly absorb the heat generated during the operation of the motor 406, preventing heat from accumulating around the motor 406. As the equipment runs for longer, when the heat absorbed by the heat dissipation block 501 reaches a certain level, the cooling fan 502 installed on the side of the heat dissipation block 501 starts, and the heat on the heat dissipation block 501 is quickly discharged to the outside of the equipment through active ventilation, achieving efficient cooling of the motor 406. At the same time, the airflow generated during the operation of the cooling fan 502 can also provide auxiliary cooling for the surrounding power board 404 and protection board 403, preventing the power board 404 from experiencing circuit failure due to overheating, and ensuring a stable power supply to the heating coil 2 and the motor 406. During this process, under the protection of the heat dissipation component 5, the motor 406 always maintains a suitable operating temperature and will not be affected by overheating, thus preventing its operating efficiency or service life from being affected. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
